Exhibit 10.2

INDEMNIFICATION AGREEMENT

          This AGREEMENT, dated as of                      , 2010, is made by and between PostRock Energy Corporation, a
Delaware corporation (the “Company”), and                      (the “Indemnitee”).

          WHEREAS, it is essential to the Company and its mission to retain and attract as officers and
directors the most capable persons available;

          WHEREAS, Indemnitee is a director of the Company;

          WHEREAS, both the Company and Indemnitee recognize the omnipresent risk of litigation and
other claims that are routinely asserted against officers and directors of companies operating in
the public arena in today’s environment, and the attendant costs of defending even wholly frivolous
claims;

          WHEREAS, it has become increasingly difficult to obtain insurance against the risk of personal
liability of officers and directors on terms providing reasonable protection to the individual at
reasonable cost to the companies;

          WHEREAS, the Bylaws of the Company provide certain indemnification rights to officers and
directors of the Company, as provided by Delaware law;

          WHEREAS, in recognition of Indemnitee’s need for substantial protection against personal
liability in order to enhance Indemnitee’s continued service to the Company in an effective manner,
the increasing difficulty in obtaining and maintaining satisfactory insurance coverage, and
Indemnitee’s reliance on assurance of indemnification, the Company wishes to provide in this
Agreement for the indemnification of and the advancing of expenses to Indemnitee to the fullest
extent permitted by law (whether partial or complete) and as set forth in this Agreement and, to
the extent insurance is maintained, for the continued coverage of Indemnitee under the Company’s
directors’ and officers’ liability insurance policies;

          NOW, THEREFORE, in consideration of the premises, the mutual covenants and agreements
contained herein and Indemnitee’s continuing service as a director of the Company, the parties
hereto agree as follows:

          1. Certain Definitions:

          (a) Change in Control: shall be deemed to have occurred if (i) there shall
have occurred an event that is or would be required to be reported with respect to the
Company in response to Item 6(e) of Schedule 14A of Regulation 14A (or in response to any
similar item on any similar schedule or form) promulgated under the Securities Exchange Act
of 1934, as amended (the “Exchange Act”), if the Company is or were subject to such
reporting requirement; (ii) any “person” (as such term is used in Sections 13(d) and 14(d)
of the Exchange Act) shall have become the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the

 

 

Company representing 40% or more of the combined voting power of the Company’s then
outstanding voting securities without prior approval of at least two-thirds of the members
of the Board of Directors in office immediately prior to such person’s attaining such
percentage interest; (iii) the Company is a party to a merger, consolidation, sale of assets
or other reorganization, or a proxy contest, as a consequence of which members of the Board
of Directors in office immediately prior to such transaction or event constitute less than a
majority of the Board of Directors thereafter; or (iv) during any period of two consecutive
years, individuals who at the beginning of such period constituted the Board of Directors
(including, for this purpose, any new director whose election or nomination for election by
the Company’s stockholders was approved by a vote of at least two-thirds of the directors
then still in office who were directors at the beginning of such period) cease for any
reason to constitute at least a majority of the Board of Directors.

          (b) Claim: any threatened, pending or completed action, suit or proceeding
(including any mediation, arbitration or other alternative dispute resolution proceeding),
whether instituted by or in the right of the Company or by any other party, or any inquiry
or investigation that Indemnitee in good faith believes might lead to the institution of any
such action, suit or proceeding, whether civil (including intentional and unintentional tort
claims), criminal, administrative, investigative or other.

          (c) Expenses: include attorneys’ fees and all other costs, expenses and
obligations paid or incurred in connection with investigating, defending, being a witness in
or participating in (including on appeal), or preparing to defend, be a witness in or
participate in any Claim relating to any Indemnifiable Event.

          (d) Indemnifiable Event: any event or occurrence related to the fact that
Indemnitee is or was a director, officer, employee, agent or fiduciary of the Company, or is
or was serving at the request of the Company as a director, officer, employee, trustee,
agent, fiduciary or other legal representative of another corporation, partnership, joint
venture, employee benefit plan, trust or other enterprise, or by reason of anything done or
not done by Indemnitee in any such capacity.

          (e) Independent Legal Counsel: an attorney or firm of attorneys, selected in
accordance with the provisions of Section 3, who shall not have otherwise performed services
for the Company or Indemnitee within the last five years (other than with respect to matters
concerning the rights of Indemnitee under this Agreement, or of other indemnitees under
similar indemnification agreements).

          (f) Reviewing Party: any appropriate person or body consisting of a member or
members of the Company’s Board of Directors or any other person or body appointed by the
Company’s Board of Directors who is not a party to the particular Claim for which Indemnitee
is seeking indemnification, or Independent Legal Counsel.

          2. Basic Indemnification Arrangement.

          (a) In the event Indemnitee was, is or becomes a party to or witness or

-2-

 

other participant in, or is threatened to be made a party to or witness or other
participant in, a Claim by reason of (or arising in part out of) an Indemnifiable Event, the
Company shall indemnify Indemnitee to the fullest extent permitted by law as soon as
practicable but in any event no later than 30 days after written demand is presented to the
Company, against any and all Expenses, judgments, fines, penalties and amounts paid in
settlement (including all interest, assessments and other charges paid or payable in
connection with or in respect of such Expenses, judgments, fines, penalties or amounts paid
in settlement) of such Claim. If so requested by Indemnitee, the Company shall advance
(within 30 days of such request) any and all Expenses to Indemnitee (an “Expense Advance”).

          (b) Notwithstanding the foregoing, (i) the obligations of the Company under Section
2(a) shall be subject to the condition that the Reviewing Party shall not have determined
(in a written opinion, in any case in which the Independent Legal Counsel referred to in
Section 3 hereof is involved) that Indemnitee would not be permitted to be indemnified under
applicable law, and (ii) the obligation of the Company to make an Expense Advance pursuant
to Section 2(a) shall be subject to the condition that, if, when and to the extent that the
Reviewing Party determines that Indemnitee would not be permitted to be so indemnified under
applicable law, the Company shall be entitled to be reimbursed by Indemnitee (who hereby
agrees to reimburse the Company) for all such amounts theretofore paid; provided, however,
that if Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be indemnified under
applicable law, any determination made by the Reviewing Party that Indemnitee would not be
permitted to be indemnified under applicable law shall not be binding and Indemnitee shall
not be required to reimburse the Company for any Expense Advance until a final judicial
determination is made with respect thereto (as to which all rights of appeal therefrom have
been exhausted or lapsed). If there has not been a Change in Control, the Reviewing Party
shall be selected by the Board of Directors, and if there has been such a Change in Control
(other than a Change in Control which has been approved by a majority of the Company’s Board
of Directors who were directors immediately prior to such Change in Control), the Reviewing
Party shall be the Independent Legal Counsel referred to in Section 3 hereof. If there has
been no determination by the Reviewing Party or if the Reviewing Party determines that
Indemnitee substantively would not be permitted to be indemnified in whole or in part under
applicable law, Indemnitee shall have the right to commence litigation in any court in the
State of Delaware having subject matter jurisdiction thereof and in which venue is proper
seeking an initial determination by the court or challenging any such determination by the
Reviewing Party or any aspect thereof, including the legal or factual bases therefor, and
the Company hereby consents to service of process and agrees to appear in any such
proceeding. Any determination by the Reviewing Party otherwise shall be conclusive and
binding on the Company and Indemnitee.

          3. Change in Control. The Company agrees that if there is a Change in Control of the
Company (other than a Change in Control which has been approved by a majority of the Company’s
Board of Directors who were directors immediately prior to such Change in

-3-

 

Control) then with respect to all matters thereafter arising concerning the rights of
Indemnitee to indemnity payments and Expense Advances under this Agreement or any other agreement
or Company Bylaw now or hereafter in effect relating to Claims for Indemnifiable Events, the
Company shall seek legal advice only from Independent Legal Counsel selected by Indemnitee and
approved by the Company (which approval shall not be unreasonably withheld). Such counsel, among
other things, shall render its written opinion to the Company and Indemnitee as to whether and to
what extent Indemnitee would be permitted to be indemnified under applicable law. The Company
agrees to pay the reasonable fees and expenses of the Independent Legal Counsel referred to above
and to fully indemnify such counsel against any and all expenses (including attorneys’ fees),
claims, liabilities and damages arising out of or relating to this Agreement or its engagement
pursuant hereto.

          4. Indemnification for Additional Expenses. The Company shall indemnify Indemnitee
against any and all expenses (including attorneys’ fees) and, if requested by Indemnitee, shall
(within 30 days of such request) advance such expenses to Indemnitee, which are incurred by
Indemnitee in connection with any action brought by Indemnitee (whether pursuant to Section 17 of
this Agreement or otherwise) for (i) indemnification or advance payment of Expenses by the Company
under this Agreement or any other agreement or Company Bylaw now or hereafter in effect relating to
Claims for Indemnifiable Events or (ii) recovery under any directors’ and officers’ liability
insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is
determined to be entitled to such indemnification, advance expense payment or insurance recovery,
as the case may be.

          5. Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement
to indemnification by the Company for some or a portion of the Expenses, judgments, fines,
penalties and amounts paid in settlement of a Claim but not, however, for all of the total amount
thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled. Moreover, notwithstanding any other provision of this Agreement, to the
extent that Indemnitee has been successful on the merits or otherwise in defense of any or all
Claims relating in whole or in part to an Indemnifiable Event or in defense of any issue or matter
therein, including dismissal without prejudice, Indemnitee shall be indemnified against all
Expenses incurred in connection therewith.

          6. Burden of Proof. In connection with any determination by the Reviewing Party or
otherwise as to whether Indemnitee is entitled to be indemnified hereunder, the burden of proof
shall be on the Company to establish that Indemnitee is not so entitled.

          7. No Presumptions. For purposes of this Agreement, the termination of any claim,
action, suit or proceeding, by judgment, order, settlement (whether with or without court approval)
or conviction, or upon a plea of nolo contendere, or its equivalent, shall not create a presumption
that Indemnitee did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable law. In addition,
neither the failure of the Reviewing Party to have made a determination as to whether Indemnitee
has met any particular standard of conduct or had any particular belief, nor an actual
determination by the Reviewing Party that Indemnitee has not met such standard of

-4-

 

conduct or did not have such belief, prior to the commencement of legal proceedings by
Indemnitee to secure a judicial determination that Indemnitee should be indemnified under
applicable law shall be a defense to Indemnitee’s claim or create a presumption that Indemnitee has
not met any particular standard of conduct or did not have any particular belief.

          8. Nonexclusivity; Subsequent Change in Law. The rights of the Indemnitee hereunder
shall be in addition to any other rights Indemnitee may have under the Company’s Bylaws or under
Delaware law, or otherwise. To the extent that a change in Delaware law (whether by statute or
judicial decision) permits greater indemnification by agreement than would be afforded currently
under the Company’s Bylaws and this Agreement, it is the intent of the parties hereto that
Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change.

          9. Liability Insurance. To the extent the Company maintains an insurance policy or
policies providing directors’ and officers’ liability insurance, Indemnitee shall be covered by
such policy or policies, in accordance with its or their terms, to the maximum extent of the
coverage available for any Company director or officer.

          10. Amendments; Waiver. No supplement, modification or amendment of this Agreement
shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

          11. Subrogation. In the event of payment under this Agreement, the Company shall be
subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall
execute all papers required and shall do everything that may be necessary to secure such rights,
including the execution of such documents necessary to enable the Company effectively to bring suit
to enforce such rights.

          12. No Duplication of Payments. The Company shall not be liable under this Agreement
to make any payment in connection with any Claim made against Indemnitee to the extent Indemnitee
has otherwise actually received payment (under any insurance policy, Bylaw or otherwise) of the
amounts otherwise indemnifiable hereunder.

          13. Binding Effect. This Agreement shall be binding upon and inure to the benefit of
and be enforceable by the parties hereto and their respective successors (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of
the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal
representatives. This Agreement shall continue in effect regardless of whether Indemnitee
continues to serve as a director of the Company or as a legal representative of any other
enterprise at the Company’s request.

          14. Severability. The provisions of this Agreement shall be severable in the event
that any of the provisions hereof (including any provision within a single section, paragraph or
sentence) is held by a court of competent jurisdiction to be invalid, void or

-5-

 

otherwise unenforceable in any respect, and the validity and enforceability of any such
provision in every other respect and of the remaining provisions hereof shall not be in any way
impaired and shall remain enforceable to the fullest extent permitted by law.

          15. Effective Date. This Agreement shall be effective as of the date hereof and shall
apply to any claim for indemnification by the Indemnitee on or after such date.

          16. Governing Law. This Agreement shall be governed by and construed and enforced in
accordance with the laws of the State of Delaware applicable to contracts made and to be performed
in such state without giving effect to the principles of conflicts of laws that would require the
application of the laws of another jurisdiction.

          17. Injunctive Relief. The parties hereto agree that Indemnitee may enforce this
Agreement by seeking specific performance hereof, without any necessity of showing irreparable harm
or posting a bond, which requirements are hereby waived, and that by seeking specific performance,
Indemnitee shall not be precluded from seeking or obtaining any other relief to which he may be
entitled.

ARTICLE II.

THE REVOLVING COMMITMENTS AND BORROWINGS

     2.01. Revolving Loans. Subject to and in reliance upon the terms, conditions, representations, and
warranties in the Loan Documents, each Lender severally, but not jointly, agrees to make revolving
loans (each such revolving loan a “Revolving Loan”) to Borrowers from time to time on any Business
Day during the period from the Closing Date to the Maturity Date, in an aggregate amount not to
exceed at any time outstanding the amount of such Lender’s Revolving Commitment as set forth on
Schedule 2.01; provided that, that after giving effect to any Borrowing, (a) the Total Outstandings
shall not exceed the lesser of (i) Aggregate
Revolving Commitments and (ii) the Borrowing Base, and (b) the aggregate Outstanding Amount of the
Revolving Loans of any Lender, plus such Lender’s Pro Rata Share of the Outstanding Amount of all
L/C Obligations shall not exceed such Lender’s Revolving Commitment; provided further that on and
after the date of this Agreement, all outstanding Revolving Loans, which had previously been
converted to term loans, shall automatically be converted to revolving loans and each Lender’s
Revolving Commitment shall be revived, renewed, and amended, in accordance with the terms of this
Agreement, as Lender’s Revolving Commitment hereunder and the Aggregate Revolving Commitment shall
be revived, renewed, and amended, in accordance with the terms of this

Borrowing Base
Credit Agreement

28

 

Agreement, as the Aggregate
Revolving Commitment hereunder. Within the limits of each Lender’s Revolving Commitment, and
subject to the other terms and conditions hereof, Borrowers may borrow under this Section 2.01,
prepay under Section 2.04, and reborrow under this Section 2.01. Revolving Loans may be Base Rate
Loans or Eurodollar Rate Loans, as further provided herein.

     2.02. Borrowing Base.

     (a) The Borrowing Base in effect as of the date of this Agreement is $225,000,000 and without
the consent of all Lenders shall not exceed such amount and each Lender may exercise its sole and
absolute discretion in determining whether to agree to any increase above $225,000,000. Upon a
sale of the Marcellus Assets, the Borrowing Base will be automatically reduced by $17,000,000
pursuant to Section 2.02(l). The Borrowing Base in existence at any time may not be increased
without the consent of one hundred percent (100%) of the Lenders.

     (b) Borrower shall deliver to Administrative Agent on or before March 31, 2011 for
distribution to each Lender the Reserve Report relating to the Proved Reserves attributable to the
Borrowing Base Oil and Gas Properties as of December 31, 2010 which shall be prepared by Cawley
Gillespie & Associates, Inc. or other independent reservoir engineers reasonably acceptable to
Administrative Agent. This Reserve Report will not be used for purposes of redetermining the
Borrowing Base pursuant to Section 2.02(c) except to the extent the March 31, 2011 Reserve Report
will be prepared on a roll forward basis using the December 31, 2010 Reserve Report,

     (c) The first redetermined Borrowing Base will be based upon a Reserve Report dated effective
as of March 31, 2011 which shall set out the Proved Reserves attributable to the Borrowing Base Oil
and Gas Properties. This Reserve Report may be prepared by one of the Borrower’s own internal
petroleum engineers, shall be certified by the President or other Responsible Officer of such
Borrower, and shall be prepared on a roll forward basis from the December 31, 2010 Reserve Report
prepared by Cawley & Gillespie & Associates, Inc. or other independent reservoir engineers
reasonably acceptable to Administrative Agent and shall include a reconciliation from the December
31, 2010 Reserve Report. This Reserve Report shall be delivered to the Administrative Agent on or
before June 30, 2011. The Administrative Agent shall make a determination of the first
redetermined Borrowing Base and submit the first redetermined Borrowing Base to the Lenders for
approval, with such first redetermined Borrowing Base to become effective on July 31, 2011, and, in
the case of an increase in the Borrowing Base, upon approval of all Lenders and the L/C Issuer, and
in the case of maintaining or decreasing the Borrowing Base, upon approval of the Administrative
Agent and the Required Lenders and in any case with the subsequent written notification from the
Administrative Agent to the Borrowers. Administrative Agent shall announce the first redetermined
Borrowing Base on or about July 31, 2011 (but no later than August 15, 2011). Such redetermined
Borrowing Base, subject to the other provisions of this Agreement, shall be the Borrowing Base
until the effective date of the next redetermination of the Borrowing Base as set out in Section
2.02(d), subject to being automatically reduced by $17,000,000 upon the sale of the
Marcellus Assets pursuant to Section 2.02(l) (if not previously reduced in accordance with
Section 2.02(l)).

     (d) After the first redetermination of the Borrowing Base to become effective July 31, 2011,
the Borrowing Base shall thereafter be redetermined from time to time pursuant to the provisions of
this Section 2.02(d) relative to the Proved Reserves attributable to the Borrowing Base Oil and Gas
Properties. On or before each March 31 and September 30 thereafter until the Maturity Date,
commencing March 31, 2012, the Borrowers shall furnish to the Administrative Agent a Reserve
Report, which shall set out, as of each preceding December 31 or June 30, as applicable, the Proved
Reserves attributable to the Borrowing Base Oil and Gas Properties. Each June 30 Reserve Report
may be prepared by one of the Borrower’s own internal petroleum engineers, shall be certified by
the President or other Responsible

Borrowing Base
Credit Agreement

29

 

Officer of such Borrower, and shall be internally generated and
prepared on a roll forward basis from the prior Reserve Report. Each Reserve Report relating to
the Proved Reserves attributable to the Borrowing Base Oil and Gas Properties as of December 31
shall be prepared by Cawley Gillespie & Associates, Inc. or other independent reservoir engineers
acceptable to Administrative Agent. Each Reserve Report as of June 30 shall include a
reconciliation from the prior December 31 Reserve Report. Upon receipt of each such Reserve Report
commencing with the Reserve Report as of December 31, 2011 delivered on or before March 31, 2012,
the Administrative Agent shall make a determination of the Borrowing Base which shall become
effective on or about April 30 or October 31 of each year, and, in the case of an increase in the
Borrowing Base, upon approval of all Lenders and the L/C Issuer, and in the case of maintaining or
decreasing the Borrowing Base, upon approval of the Administrative Agent and the Required Lenders
and in any case with the subsequent written notification from the Administrative Agent to the
Borrowers. Administrative Agent shall announce the redetermined Borrowing Base on or about October
31 (but no later than November 15) with respect to the June 30 Reserve Report (delivered in
September) and on or about April 30 of each year (but no later than May 15 of each year) with
respect to the December 31 Reserve Report (delivered in March). Such redetermined Borrowing Base,
subject to the other provisions of this Agreement, shall be the Borrowing Base until the effective
date of the next redetermination of the Borrowing Base as set out in this Section 2.02.

     (e) After the second redetermination of the Borrowing Base effective on April 30, 2012, during
each successive period between scheduled redeterminations of the Borrowing Base, the Administrative
Agent shall have the right to initiate, and shall initiate at the request of Required Lenders, one
(1) unscheduled redetermination of the Borrowing Base by requesting in writing that the Borrowers
provide an unscheduled internally generated Reserve Report regarding the Proved Reserves
attributable to the Borrowing Base Oil and Gas Properties with an effective date not more than
sixty (60) days prior to the Borrower’s delivery of such Reserve Report to the Administrative
Agent, and such Reserve Report shall be delivered to the Administrative Agent within thirty (30)
days after the Borrower’s receipt of such written request; provided, however, that there shall not
be any more than two (2) unscheduled redeterminations of the Borrowing Base under this Section
2.02(e) during any twelve (12) month period.

     (f) In addition to the redetermination provided for in Section 2.02(e), upon a Material
Disposition or any material (in the judgment of the Administrative Agent or the Required Lenders)
defect in title, or failure of title to, five percent (5%) or more of the PV-10 of the Borrowing
Base Oil and Gas Properties, the Administrative Agent may, and upon the request of the Required
Lenders shall, redetermine the Borrowing Base by requesting in writing that the Borrowers provide
an unscheduled internally generated Reserve Report regarding the Proved Reserves attributable to
the Borrowing Base Oil and Gas Properties with an effective date not more than sixty (60) days
prior to the Borrowers’ delivery of such Reserve Report to the Administrative Agent, and such
Reserve Report shall be delivered to the Administrative Agent within thirty days after the
Borrowers’ receipt of such written request.

     (g) If prior to December 31, 2011 any Swap Contracts are amended, modified, terminated or
unwound and after taking into account the effect of any such amendment or modification and the
effect of any new Swap Contracts entered into, the Borrowing Base would be reduced by more than
$11,250,000, then the Borrowing Base will be automatically reduced by an amount equal to the excess
of such reduction in the Borrowing Base over $11,250,000.

     (h) During each period between scheduled redeterminations of the Borrowing Base, the Borrowers
shall have the right to request, by written notice to the Administrative Agent, one (1) unscheduled
redetermination of the Borrowing Base, subject to contemporaneously providing to the Administrative
Agent a Reserve Report with an effective date not more than sixty days prior to the date of such
notice; provided, however, that there shall not be any more than two (2) unscheduled
redeterminations of the Borrowing Base under this Section 2.02(h) during any twelve (12) month
period.

     (i) In addition to the redetermination provided for in Section 2.02(f), upon a Material
Acquisition, the Borrowers may, from time to time upon written notice to the Administrative Agent,
propose to add Oil and Gas Properties to the Borrowing Base Oil and Gas Properties and other
Collateral to the Borrowing Base. Any such proposal to add Oil and Gas Properties to the Borrowing
Base Oil and Gas Properties shall be accompanied by a Reserve Report applicable to such properties
that conforms to the requirements of Section 2.02, and evidence sufficient to establish that the
Borrowers or the other applicable Loan Party has Marketable Title to such Oil and Gas Properties or
other Collateral, and any such addition shall become effective at such time as: (a) the
Administrative Agent, with the approval of all the Lenders, has made a determination of the amount
by which the Borrowing Base would be increased as the result of such addition and (b) the
conditions set out in Article IV hereof, to the extent they are applicable to such additional Oil
and Gas Properties or other Collateral of the Borrowers, have been satisfied. In determining the
increase in the Borrowing Base pursuant to this Section, the Administrative Agent and the Lenders
shall apply the parameters and other credit factors set out in this Section 2.02.

     (j) If in connection with a redetermination of the Borrowing Base maintaining or decreasing
the Borrowing Base, the Required Lenders cannot otherwise agree on the new Borrowing Base, then the
Borrowing Base shall be the Administrative Agent’s calculation of the “weighted arithmetic average”
(as hereinafter calculated) of the Borrowing Base, as determined by each individual Lender and
communicated to the Administrative Agent in writing. However, the amount of the Borrowing Base
shall never be increased at any time without the unanimous consent of all the Lenders,
notwithstanding anything else herein to the contrary. For purposes of this paragraph, the
“weighted arithmetic average” of the Borrowing Base shall be determined by first multiplying the
Borrowing Base proposed in writing to Administrative Agent by each Lender by such Lender’s Pro Rata
Share, and then adding the results of each such calculation, with the resultant sum being the
Borrowing Base.

     (k) The Borrowing Base shall represent the Required Lenders’ approval (except where unanimous
consent is required) of the Administrative Agent’s determination, in accordance with their
customary oil and gas lending practices, of the maximum Credit Extensions that may be supported by
the Borrowing Base Oil and Gas Properties and the Borrowers acknowledge, for purposes of this
Agreement, such determination by the Administrative Agent as being the maximum Credit Extensions
that may be supported by the Borrowing Base Oil and Gas Properties. In making any redetermination
of the Borrowing Base, the Administrative Agent and the Lenders shall apply the parameters and
other credit factors consistently applied then generally being utilized by the Administrative Agent
and each such Lender, respectively, for Borrowing Base redeterminations for other similarly
situated borrowers. The Borrowers, Lenders and the Administrative Agent acknowledge that (i) due
to the uncertainties of the oil and gas extraction process, the Borrowing Base Oil and Gas
Properties are not subject to evaluation with a high degree of accuracy and are subject to
potential rapid deterioration in value, (ii) for this reason and
the difficulties and expenses involved in liquidating and collecting against the Borrowing
Base Oil and Gas Properties, the Administrative Agent’s determination of the maximum Credit
Extensions with respect to the Borrowing Base Oil and Gas Properties contains an equity cushion,
which equity cushion is acknowledged by the Borrowers as essential for the adequate protection of
the Lenders, and (iii) decisions regarding the Borrowing Base shall be made by the Lenders in their
sole discretion.

     (l) Upon the sale of the Marcellus Assets, and contemporaneously therewith, the Borrowing Base
will be reduced by $17,000,000.

     (m) Upon Borrowers’ failure to make the minimum Capital Expenditures required by the dates
specified in Section 6.22, the Borrowing Base will be reduced by an amount equal to such shortfall
as provided in Section 6.22.

     2.03. Borrowings, Conversions and Continuations of Loans.

     (a) Each Borrowing, each conversion of Revolving Loans from one Type to the other, and each
continuation of Revolving Loans as the same Type shall be made upon a Borrower’s irrevocable notice
to the Administrative Agent, which may be given by telephone. Each such notice must be received by
the Administrative Agent not later than noon, New York time, (i) three Business Days prior to the
requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans, and
(ii) one Business Day prior to the conversion of Eurodollar Rate Loans to Base Rate Loans, or the
requested date of any Borrowing of Base Rate Loans. Each such telephonic notice must be confirmed
promptly by delivery to the Administrative Agent of a written Borrowing Notice, appropriately
completed and signed by a Responsible Officer of a Borrower. Each Borrowing of, conversion to or
continuation of Eurodollar Rate Loans shall be in a principal amount of $1,000,000 or a whole
multiple of $1,000,000 in excess thereof. Each Borrowing of or conversion to Base Rate Loans shall
be in a principal amount of $500,000 or a whole multiple of $500,000 in excess thereof; provided
that any Base Rate Loan may be in an aggregate amount that is equal to the entire unused balance of
the Aggregate Revolving Commitment or that is required to finance the Unreimbursed Amount as
provided in Section 2.14(c)(i). Each Borrowing Notice (whether telephonic or written) shall
specify (i) whether a Borrower is requesting a Borrowing, a conversion of Revolving Loans from one
Type to the other, or a continuation of Revolving Loans as the same Type, (ii) the requested date
of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day),
(iii) the principal amount of Revolving Loans to be borrowed, converted or continued, (iv) the Type
of Loans to be borrowed or to which existing Revolving Loans are to be converted, and (v) if
applicable, the duration of the Interest Period with respect thereto. If a Borrower fails to
specify a Type of Revolving Loan in a Borrowing Notice or if a Borrower fails to give a timely
notice requesting a conversion or continuation, then the applicable Revolving Loans shall be made
or continued as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate
Loans shall be effective as of the last day of the Interest Period then in effect with respect to
the applicable Eurodollar Rate Loans. If a Borrower requests a Borrowing of, conversion to, or
continuation of Eurodollar Rate Loans in any such Borrowing Notice, but fails to specify an
Interest Period, it will be deemed to have specified an Interest Period of one month.

     (b) Following receipt of a Borrowing Notice, the Administrative Agent shall promptly notify
each Lender of its Pro Rata Share of the applicable Borrowing, and if no timely notice of a
conversion or continuation is provided by such Borrower, the Administrative Agent shall notify each
Lender of the details of any automatic conversion to Base Rate Loans described in the preceding
subsection. In the case of a Borrowing, each Lender shall make the amount of its Revolving Loan
available to the Administrative Agent in immediately available funds at the Administrative Agent’s
Office not later than noon, New York
time, on the Business Day specified in the applicable Borrowing Notice. Upon satisfaction of
the applicable conditions set forth in Sections 4.01 and 4.02, as applicable, the Administrative
Agent shall make all funds so received available to such Borrower in like funds as received by the
Administrative Agent either by (i) crediting the account of such Borrower on the books of the
Administrative Agent with the amount of such funds or (ii) wire transfer of such funds, in each
case in accordance with instructions provided to the Administrative Agent by such Borrower;
provided, however, that if, on the date of the Borrowing there are L/C Borrowings outstanding, then
the proceeds of such Borrowing shall be applied, first, to the payment in full of any such L/C
Borrowings, and second, to such Borrower as provided above.

     (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be continued or converted
only on the last day of the Interest Period for such Eurodollar Rate Loan. During the existence of
an Event of Default, no Revolving Loans may be requested as, converted to or continued as
Eurodollar Rate Loans without the consent of the Required Lenders, and the Required Lenders may
demand that any or all of the then outstanding Eurodollar Rate Loans be converted immediately to
Base Rate Loans. The

Borrowing Base
Credit Agreement

32

 

Administrative Agent shall promptly notify the Borrowers and the Lenders of
the interest rate applicable to any Eurodollar Rate Loan upon determination of such interest rate.
The determination of the Eurodollar Rate by the Administrative Agent shall be conclusive in the
absence of manifest error.

     (d) After giving effect to all Borrowings, all conversions of Revolving Loans from one Type to
the other, and all continuations of Revolving Loans as the same Type, there shall not be more than
six (6) Interest Periods in effect at any given time with respect to Revolving Loans.

     2.04. Prepayments.

     (a) Optional Prepayments. The Borrowers (or one or more of them) may, upon delivery
of a Repayment Notice to the Administrative Agent, at any time or from time to time voluntarily
prepay in whole or in part Revolving Loans outstanding under the Facility without premium or
penalty; provided that (i) such notice must be received by the Administrative Agent not later than
noon, New York time, (A) three Business Days prior to any date of prepayment of Eurodollar Rate
Loans, and (B) the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate
Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess
thereof; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $1,000,000
or a whole multiple of $1,000,000 in excess thereof. Each such notice shall specify the date and
amount of such prepayment and the Type(s) of Revolving Loans to be prepaid. The Administrative
Agent will promptly notify each Lender of its receipt of each such notice, and of such Lender’s Pro
Rata Share of such prepayment. If such notice is given by a Borrower, such Borrower shall make
such prepayment and the payment amount specified in such notice shall be due and payable on the
date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all
accrued interest thereon, together with any additional amounts required pursuant to Section 3.05.
Each such prepayment shall be applied to the Revolving Loans of the Lenders in accordance with
their respective Pro Rata Shares.

     Unless a Default or Event of Default has occurred and is continuing or would arise as a result
thereof, any payment or prepayment of the Revolving Loans may be reborrowed by Borrowers, subject
to the terms and conditions hereof.

     (b) Mandatory Prepayments. If for any reason (including a redetermination of the
Borrowing Base) a Borrowing Base Deficiency exists (other than (x) as a result of a Credit
Extension having been mistakenly or impermissibly made which causes the Total Outstandings to
exceed the lesser of (A)
Aggregate Revolving Commitments and (B) the Borrowing Base and (y) as a result of a sale of
the Marcellus Assets, in both of which cases any Borrowing Base Deficiency is required to be cured
by prepayment, in the case of clause (x), on the Business Day after the Borrower is advised of the
Borrowing Base Deficiency, and in the case of clause (y), on the date of the sale of the Marcellus
Assets), the Borrowers shall within thirty (30) days after being notified of such Borrowing Base
Deficiency by the Administrative Agent indicate in writing the Borrowers’ election to do one or
more of the following to eliminate such Borrowing Base Deficiency:

     (i) prepay Revolving Loans and/or Cash Collateralize the L/C Obligations in an
aggregate amount equal to such Borrowing Base Deficiency within thirty (30) days of such
election,

     (ii) prepay Revolving Loans and/or Cash Collateralize the L/C Obligations in an
aggregate amount equal to such Borrowing Base Deficiency in six (6) equal monthly
installments beginning on or before the thirtieth (30th) day after being notified of the
Borrowing Base Deficiency; and

Borrowing Base
Credit Agreement

33

 

     (iii) add to the Borrowing Base Oil and Gas Properties additional Oil and Gas
Properties of the Borrowers or another Loan Party sufficient in value, as determined
pursuant to Section 2.02, or add other Collateral to increase the Borrowing Base to equal
or exceed the Total Outstandings.

     (c) Mandatory Prepayments of Borrowing Base Value from Net Available Cash. An amount
equal to Borrowing Base Value of any Collateral sold in a Material Disposition (other than a
disposition of the Marcellus Assets which shall be governed by subsection (d)) shall be prepaid by
the selling Borrower or any of its Subsidiaries (other than the Excluded Subsidiaries) out of the
Net Available Cash received by such Borrower or such Subsidiary. On any date on which a Borrower
or another Loan Party makes a Material Disposition of any of the Borrowing Base Oil and Gas
Properties, the Borrowing Base shall be automatically reduced by the Borrowing Base Value of the
properties so Disposed. Net Available Cash received by the Borrower or such Subsidiary shall be
used to prepay outstanding Revolving Loans in an amount at least equal to the excess of Total
Outstandings over the reduced Borrowing Base (or to Cash Collateralize Letters of Credit, if no
Revolving Loans are outstanding). Following any such prepayment and reduction of the Borrowing
Base, any Borrower shall have the right to request a Borrowing Base redetermination (which right
shall be in addition to any Borrower’s right to request a redetermination of the Borrowing Base
pursuant to Section 2.02(h)). (For clarification, a prepayment of the Revolving Loans may be
reborrowed, if, after a Borrowing Base redetermination, there is sufficient Borrowing Base to
permit such reborrowing.)

     (d) Mandatory Prepayments from Sale of Marcellus Assets. Net Available Cash received
by MidContinent from the Disposition of the Marcellus Assets shall be prepaid contemporaneously
with the closing of any such Disposition. On the date MidContinent Disposes of the Marcellus
Assets, the Borrowing Base shall be automatically reduced by $17,000,000 pursuant to Section
2.02(l). Net Available Cash received by MidContinent from the Disposition of the Marcellus Assets
shall be used to prepay outstanding Revolving Loans in an amount at least equal to the excess of
Total Outstandings over the reduced Borrowing Base (or to Cash Collateralize Letters of Credit, if
no Revolving Loans are outstanding). For the avoidance of doubt, any prepayment resulting in Total
Outstandings being less than the reduced Borrowing Base may be reborrowed.

     (e) Closing Date Prepayment Amount and Outstandings. On the Closing Date,
MidContinent or PESC shall make a prepayment of the Indebtedness outstanding (i) under the Prior
First Lien Credit Agreement in an amount equal to the Closing Date Prepayment Amount relating
thereto; and
under the Prior Midstream Agreement in an amount equal to the Closing Date Prepayment Amount
relating thereto.

     (f) Change of Control. Upon a Change of Control, the Borrowers shall repay to the
Lenders the aggregate principal amount of Revolving Loans outstanding, together with all accrued
and unpaid interest and fees and Cash Collateralize the L/C Obligations contemporaneously with such
Change of Control.

     (g) Prepayments: Interest/Consequential Loss. All prepayments under this Section 2.04
shall be made together with accrued interest to the date of such prepayment on the principal amount
prepaid and any amounts due under Section 3.05.

     2.05. Reduction or Termination of Revolving Commitments. The Borrowers may, upon notice to the
Administrative Agent, terminate the Aggregate Revolving Commitment or permanently reduce the
Aggregate Revolving Commitment to an amount not less than the sum of the Outstanding Amount of the
then existing (i) unpaid principal balance of the Revolving Loans and (ii) L/C Obligations;
provided that (i) any such notice shall be received by the Administrative Agent not later than
noon, three

Borrowing Base
Credit Agreement

34

 

Business Days prior to (or if all the outstanding Borrowings are Base Rate Loans, no
later than noon on) the date of termination or reduction, and (ii) any such partial reduction shall
be in an aggregate amount of $1,000,000 or any whole multiple of $1,000,000 in excess thereof. The
Administrative Agent shall promptly notify the Lenders of any such notice of reduction or
termination. Once reduced in accordance with this Section, the Aggregate Revolving Commitment may
not be increased. Any reduction of the Aggregate Revolving Commitment shall be applied to the
Revolving Commitment of each Lender according to its Pro Rata Share. Except in connection with a
termination or reduction of the entire Aggregate Revolving Commitment, all commitment fees on the
portion of the Aggregate Revolving Commitment so terminated which have accrued to the effective
date of any termination of the Aggregate Revolving Commitment shall at Administrative Agent’s
option either be paid on the effective date of such termination or on the date when such commitment
fee would otherwise be due.

     2.06. Repayment of Revolving Loans. The Borrowers shall repay to the Lenders on the Maturity Date
the aggregate principal amount of Revolving Loans outstanding on such date, together with all
accrued and unpaid interest and fees.

     2.07. Interest. (a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate
Loan shall bear interest on the outstanding principal amount thereof for each Interest Period at a
rate per annum equal to the Eurodollar Rate for such Interest Period plus the Applicable Rate and
(ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof from the
applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate.

     (b) If any amount payable by the Borrowers under any Loan Document is not paid when due (after
the expiration of any applicable grace periods), whether at stated maturity by acceleration or
otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at
all times equal to the Default Rate to the fullest extent permitted by applicable Laws.
Furthermore, while any Event of Default exists or after acceleration (i) the Borrowers shall pay
interest on the principal amount of all outstanding Obligations at a fluctuating interest rate per
annum at all times equal to the Default Rate to the fullest extent permitted by applicable Law, and
(ii) accrued and unpaid interest on past due amounts
(including interest on past due interest, to the extent allowed by Law) shall be due and
payable upon demand.

     (c) Interest on each Revolving Loan shall be due and payable in arrears on each Interest
Payment Date applicable thereto and at such other times as may be specified herein. Interest
hereunder shall be due and payable in accordance with the terms hereof before and after judgment,
and before and after the commencement of any proceeding under any Debtor Relief Law.

     (d) If the designated rate applicable to any Borrowing exceeds the Maximum Rate, the rate of
interest on such Borrowing shall be limited to the Maximum Rate, but any subsequent reductions in
such designated rate shall not reduce the rate of interest thereon below the Maximum Rate until the
total amount of interest accrued thereon equals the amount of interest which would have accrued
thereon if such designated rate had at all times been in effect. In the event that at maturity
(stated or by acceleration), or at final payment of the Outstanding Amount of any Revolving Loans
or L/C Obligations, the total amount of interest paid or accrued is less than the amount of
interest which would have accrued if such designated rates had at all times been in effect, then,
at such time and to the extent permitted by Law, the Borrowers shall pay an amount equal to the
difference between (a) the lesser of the amount of interest which would have accrued if such
designated rates had at all times been in effect and the amount of interest which would have
accrued if the Maximum Rate had at all times been in effect, and (b) the amount of interest
actually paid or accrued on such Outstanding Amount.

     2.08. Fees. (a) Commitment Fee. The Borrowers shall pay to the Administrative Agent for
the account of each Lender (other than a Defaulting Lender) in accordance with its Pro Rata Share,
a commitment fee equal to the Applicable Rate times the actual daily amount by which the lesser of
(i) the Aggregate Revolving Commitment (subject to reduction pursuant to Sections 2.04 and 2.05)
and (ii) the Borrowing Base exceeds the sum of (1) the Outstanding Amount of Revolving Loans plus
(2) the Outstanding Amount of L/C Obligations. The commitment fee shall accrue at all times from
the Closing Date until the Maturity Date (except as to any Defaulting Lender, during any period in
which a Lender is a Defaulting Lender) and shall be due and payable quarterly in arrears on the
last Business Day of each March, June, September and December, commencing with the first such date
to occur after the Closing Date, and on the Maturity Date. The commitment fee shall accrue at all
times (except as respects a Defaulting Lender), including at any time during which one or more of
the conditions in Article IV is not met.

     (b) Amendment Fees. On the Closing Date, the Borrowers irrevocably agree to pay the
amendment fees previously incurred under the Prior First Lien Credit Agreement and the Prior Second
Lien Credit Agreement in cash. Such previously incurred amendment fees equal $725,000 to be paid
to the lenders party to the Prior First Lien Credit Agreement and $157,000 to be paid to the
lenders party to the Prior Second Lien Credit Agreement. No new or additional amendment fees shall
accrue by reason of the amendment and restatement of the Prior First Lien Credit Agreement and the
Prior Second Lien Credit Agreement evidenced by this Agreement.

     (c) Processing Fee. No Section 10.07(b)(iii) processing and recordation fee shall be
due with reference to any assignment of any indebtedness and liens under the Prior Credit
Agreements effective on the Closing Date.

     2.09. Computation of Interest and Fees. Computation of interest on Base Rate Loans shall be
calculated on the basis of a year of 365 or 366 days, as the case may be, and the actual number of
days elapsed. Computation of all other types of
interest (including interest on Eurodollar Rate Loans) and all fees shall be calculated on the
basis of a year of 360 days and the actual number of days elapsed, which results in a higher yield
to the payee thereof than a method based on a year of 365 or 366 days. Interest shall accrue on
each Revolving Loan for the day on which the Revolving Loan is made, and shall not accrue on a
Revolving Loan, or any portion thereof, for the day on which the Revolving Loan or such portion is
paid; provided that any Revolving Loan that is repaid on the same day on which it is made shall
bear interest for one day.

     2.10. Evidence of Debt. (a) The Credit Extensions made by each Lender shall be evidenced by one
or more accounts or records maintained by such Lender and by the Administrative Agent in the
ordinary course of business. The accounts or records maintained by the Administrative Agent and
each Lender shall be conclusive absent manifest error of the amount of the Revolving Loans made by
the Lenders to the Borrowers and the interest and payments thereon. Any failure so to record or
any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers
hereunder to pay any amount owing with respect to the Revolving Loans or the L/C Obligations. In
the event of any conflict between the accounts and records maintained by any Lender and the
accounts and records of the Administrative Agent in respect of such matters, the accounts and
records of such Lender shall control absent manifest error. Upon the request of any Lender made
through the Administrative Agent, such Lender’s Revolving Loans may be evidenced by one or more
Revolving Notes. Each Lender may attach schedules to its Revolving Note(s) and endorse thereon the
date, Type (if applicable), amount and maturity of the applicable Revolving Loans and payments with
respect thereto.

     (b) In addition to the accounts and records referred to in subsection (a), each Lender and the
Administrative Agent shall maintain in accordance with its usual practice accounts or records
evidencing

Borrowing Base
Credit Agreement

36

 

the purchases and sales by such Lender of participations in Letters of Credit. In the
event of any conflict between the accounts and records maintained by the Administrative Agent and
the accounts and records of any Lender in respect of such matters, the accounts and records of the
Administrative Agent shall control.

     2.11. Payments Generally.

     (a) All payments to be made by the Borrowers shall be made without condition or deduction for
any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein,
all payments by the Borrowers hereunder shall be made to the Administrative Agent, for the account
of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office in
Dollars and in immediately available funds not later than noon, New York time, on the date
specified herein. The Administrative Agent will promptly distribute to each Lender its Pro Rata
Share (or other applicable share as provided herein) of such payment in like funds as received by
wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent
after noon, New York time, shall be deemed received on the next succeeding Business Day and any
applicable interest or fee shall continue to accrue.

     (b) Subject to the definition of “Interest Period,” if any payment to be made by the Borrowers
shall come due on a day other than a Business Day, payment shall be made on the next following
Business Day, and such extension of time shall be reflected in computing interest or fees, as the
case may be.

     (c) If no Event of Default exists and if no order of application is otherwise specified in the
Loan Documents, payments and prepayments of the Obligations shall be applied first to fees, second
to accrued interest then due and payable on the Outstanding Amount of Revolving Loans and L/C
Obligations, and then to the remaining Obligations in the order and manner as Borrowers may direct.

     (d) If at any time insufficient funds are received by and available to the Administrative
Agent to pay fully the Obligations, or if an Event of Default exists, any payment or prepayment
shall be applied in the following order: (i) to the payment of enforcement expenses incurred by the
Administrative Agent, including Attorney Costs; (ii) to the ratable payment of all fees, expenses
and indemnities (including amounts payable under Article III) for which the Administrative Agent,
Lenders or Approved Hedge Counterparty have not been paid or reimbursed in accordance with the Loan
Documents or Approved Hedge Counterparty Swap Contract (as used in this Section 2.11(d)(ii), a
"ratable payment” for any Lender, the Administrative Agent or Approved Hedge Counterparty shall be,
on any date of determination, that proportion which the portion of the total fees, expenses and
indemnities owed to such Lender, the Administrative Agent or Approved Hedge Counterparty bears to
the total aggregate fees, expenses and indemnities owed to all Lenders, the Administrative Agent
and Approved Hedge Counterparty on such date of determination); (iii) to the ratable payment of
accrued and unpaid Letter of Credit fees, the Outstanding Amount of L/C Borrowings, accrued and
unpaid interest on, and principal of, the Outstanding Amount of Revolving Loans and the Outstanding
Amount of Obligations under Lender Hedging Agreements; (it being understood that for purposes of
this clause (iii) the Outstanding Amount of Obligations under Lender Hedging Agreements refers to
payments owing in connection with an Early Termination Date as defined in the 2002 Master Agreement
form promulgated by the ISDA (or equivalent type payment obligation if some other form of Swap
Contract is in effect)(as used in this Section 2.11(d)(iii), “ratable payment” means for any Lender
(or Lender Affiliate, in the case of Lender Hedging Agreements or the Approved Hedge Counterparty,
in the case of an Approved Hedge Counterparty Swap Contract), on any date of determination, that
proportion which the accrued and unpaid Letter of Credit fees, the Outstanding Amount of L/C
Borrowings, accrued and unpaid interest on, and principal of, the Outstanding Amount of Revolving
Loans and the Outstanding Amount of Obligations under Lender Hedging Agreements owed to such Lender
(or Lender Affiliate, in the case of Lender Hedging

Borrowing Base
Credit Agreement

37

 

Agreements or the Approved Hedge Counterparty,
in the case of an Approved Hedge Counterparty Swap Contract) bears to the accrued and unpaid Letter
of Credit fees, the Outstanding Amount of L/C Borrowings, accrued and unpaid interest on, and
principal of, the Outstanding Amount of Revolving Loans and the Outstanding Amount of Obligations
under Lender Hedging Agreements owed to all Lenders) (and Affiliates, in the case of Lender Hedging
Agreements or the Approved Hedge Counterparty, in the case of an Approved Hedge Counterparty Swap
Contract)); (iv) to Cash Collateralize the Letters of Credit; and (v) to the payment of the
remaining Obligations, if any, in the order and manner the Required Lenders deem appropriate.
Subject to Section 2.14(g), amounts used to Cash Collateralize the aggregate undrawn amount of
Letters of Credit pursuant to clause (iv) above shall be applied to satisfy drawings under such
Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral after all
Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied
to the other Obligations, if any, in the order set forth above.

     (e) Unless any Borrower or any Lender has notified the Administrative Agent prior to the date
any payment is required to be made by it to the Administrative Agent hereunder, that such Borrower
or such Lender, as the case may be, will not make such payment, the Administrative Agent may assume
that such Borrower or such Lender, as the case may be, has timely made such payment and may (but
shall not be so required to), in reliance thereon, make available a corresponding amount to the
Person entitled thereto. If and to the extent that such payment was not in fact made to the
Administrative Agent in immediately available funds, then:

     (i) if a Borrower failed to make such payment, each Lender shall forthwith on demand
repay to the Administrative Agent the portion of such assumed payment that was made
available to such Lender in immediately available funds, together with interest thereon in
respect of each day from and including the date such amount was made available by the
Administrative Agent to such Lender to the date such amount is repaid to the
Administrative Agent in immediately available funds, at the Federal Funds Rate from time
to time in effect; and

     (ii) if any Lender failed to make such payment, such Lender shall forthwith on demand
pay to the Administrative Agent the amount thereof in immediately available funds,
together with interest thereon for the period from the date such amount was made available
by the Administrative Agent to the Borrowers to the date such amount is recovered by the
Administrative Agent (the “Compensation Period”) at a rate per annum equal to the Federal
Funds Rate from time to time in effect. If such Lender pays such amount to the
Administrative Agent, then such amount shall constitute such Lender’s Revolving Loan,
included in the applicable Borrowing. If such Lender does not pay such amount forthwith
upon the Administrative Agent’s demand therefor, the Administrative Agent may make a
demand therefor upon the Borrowers, and the Borrowers shall pay such amount to the
Administrative Agent, together with interest thereon for the Compensation Period at a rate
per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing
herein shall be deemed to relieve any Lender from its obligation to fulfill its Revolving
Commitment or to prejudice any rights which the Administrative Agent or the Borrowers may
have against any Lender as a result of any default by such Lender hereunder.

     A notice of the Administrative Agent to any Lender with respect to any amount owing under this
subsection (e) shall be conclusive, absent manifest error.

     (f) If any Lender makes available to the Administrative Agent funds for any Revolving Loan to
be made by such Lender as provided in the foregoing provisions of this Article II, and the
conditions to the applicable Borrowing set forth in Article IV are not satisfied or waived in
accordance with the terms

Borrowing Base
Credit Agreement

38

 

hereof, the Administrative Agent shall return such funds (in like funds
as received from such Lender) to such Lender, without interest.

     (g) The obligations of the Lenders hereunder to make Revolving Loans are several and not
joint. The failure of any Lender to make any Revolving Loan on any date required hereunder shall
not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender
shall be responsible for the failure of any other Lender to so make its Revolving Loan or purchase
its participation.

     (h) Nothing herein shall be deemed to obligate any Lender to obtain the funds for any
Revolving Loan in any particular place or manner or to constitute a representation by any Lender
that it has obtained or will obtain the funds for any Revolving Loan in any particular place or
manner.

     2.12. Sharing of Payments. If, other than as expressly provided elsewhere herein, any Lender shall
obtain on account of the Revolving Loans made by it, or the participations in the L/C Obligations,
any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) in excess of its ratable share (or other share contemplated hereunder) thereof, such
Lender shall immediately (a) notify the Administrative Agent, of such fact, and (b) purchase from
the other Lenders such participations in the Revolving Loans made by them, and/or such
subparticipations in the participations in L/C Obligations held by them, as shall be necessary to
cause such purchasing Lender to share the excess payment in respect of such Revolving Loan or such
participations, as the case may be, pro rata with each of them; provided, however, that if all or
any portion of such excess payment is thereafter recovered from the
purchasing Lender, such purchase shall to that extent be rescinded and each other Lender shall
repay to the purchasing Lender the purchase price paid therefor, together with an amount equal to
such paying Lender’s ratable share (according to the proportion of (i) the amount of such paying
Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrowers agree that any Lender so purchasing a participation from
another Lender may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off, but subject to Section 10.09) with respect to such participation
as fully as if such Lender were the direct creditor of the Borrowers in the amount of such
participation. The Administrative Agent will keep records (which shall be conclusive and binding
in the absence of manifest error) of participations purchased under this Section and will in each
case notify the Lenders following any such purchases or repayments. Each Lender that purchases a
participation pursuant to this Section shall from and after such purchase have the right to give
all notices, requests, demands, directions and other communications under this Agreement with
respect to the portion of the Obligations purchased to the same extent as though the purchasing
Lender were the original owner of the Obligations purchased.

     2.13. Pari Passu Lien Securing Lender Hedging Obligations. All Obligations arising under the Loan
Documents, including, without limitation, Obligations under this Agreement and Obligations under
any Lender Hedging Agreement (but not Indebtedness of any Borrower or Borrower Affiliate owing to
any non-Lender, non-Lender Affiliate or any Person other than the Approved Hedge Counterparty which
enters into a Swap Contract with any Borrower or any Borrower Affiliate), shall be secured pari
passu by the Collateral. No Lender, any Affiliate of a Lender or the Approved Hedge Counterparty
shall have any voting rights under any Loan Document as a result of the existence of obligations
owed to it under any such Lender Hedging Agreement.

     2.14. Letters of Credit. (a) The Letter of Credit Commitment.

     (i) Subject to the terms and conditions set forth herein, (A) the L/C Issuer agrees,
in reliance upon the agreements of the other Lenders set forth in this Section 2.14, (1)
from time

Borrowing Base
Credit Agreement

39

 

to time on any Business Day during the period from the Closing Date until the
Letter of Credit Expiration Date, to issue Letters of Credit for the account of any
Borrower (and such Letters of Credit may be issued for the benefit of any Borrower, or any
of its Subsidiaries (other than the Excluded Subsidiaries)), and to amend or renew Letters
of Credit previously issued by it, in accordance with subsection (b) below, and (2) to
honor drafts under the Letters of Credit; and (B) the Lenders severally agree to
participate in Letters of Credit issued for the account of the any Borrower; provided that
the L/C Issuer shall not be obligated to make any L/C Credit Extension with respect to any
Letter of Credit, and no Lender shall be obligated to participate in any Letter of Credit,
if as of the date of such L/C Credit Extension, (x) the Total Outstandings would exceed
the Aggregate Revolving Commitment, (y) the aggregate Outstanding Amount of the Revolving
Loans of any Lender, plus such Lender’s Pro Rata Share of the Outstanding Amount of all
L/C Obligations would exceed such Lender’s Revolving Commitment, or (z) the Outstanding
Amount of the L/C Obligations would exceed the Letter of Credit Sublimit. Within the
foregoing limits, and subject to the terms and conditions hereof, any Borrower’s ability
to obtain Letters of Credit shall be fully revolving, and accordingly any Borrower may,
during the foregoing period, obtain Letters of Credit to replace Letters of Credit that
have expired or that have been drawn upon and reimbursed. The Existing Letter of Credit
shall be deemed to have been issued pursuant hereto, and from and after the Closing Date
shall be subject to and governed by the terms and conditions hereof.

     (ii) The L/C Issuer shall be under no obligation to issue any Letter of Credit if:

     (A) any order, judgment or decree of any Governmental Authority or arbitrator
shall by its terms purport to enjoin or restrain the L/C Issuer from issuing such
Letter of Credit, or any Law applicable to the L/C Issuer or any request or
directive (whether or not having the force of law) from any Governmental Authority
with jurisdiction over the L/C Issuer shall prohibit, or request that the L/C Issuer
refrain from, the issuance of letters of credit generally or such Letter of Credit
in particular or shall impose upon the L/C Issuer with respect to such Letter of
Credit any restriction, reserve or capital requirement (for which the L/C Issuer is
not otherwise compensated hereunder) not in effect on the Closing Date, or shall
impose upon the L/C Issuer any unreimbursed loss, cost or expense which was not
applicable on the Closing Date and which the L/C Issuer in good faith deems material
to it; provided, however, if any of the forgoing occur, then the Borrowers may, at
their sole expense and effort, upon notice to L/C Issuer and Administrative Agent,
require the L/C Issuer to resign as L/C Issuer and a new replacement L/C Issuer be
appointed, which new replacement L/C Issuer shall be reasonably acceptable to the
Administrative Agent;

     (B) subject to Section 2.14(b)(iii), the expiry date of such requested Letter
of Credit would occur more than twelve months after the date of issuance or last
renewal, unless the Required Lenders have approved such expiry date;

     (C) the expiry date of such requested Letter of Credit would occur after the
Letter of Credit Expiration Date, unless all the Lenders have approved such expiry
date;

     (D) the issuance of such Letter of Credit would violate one or more policies of
the L/C Issuer generally applicable to all borrowers; or

     (E) such Letter of Credit is in a face amount less than $100,000 (unless upon a
Borrower’s request the L/C Issuer agrees to issue a Letter of Credit for a lesser

Borrowing Base
Credit Agreement

40

 

amount), or is to be used for a purpose other than as described in Section 6.12 or
is denominated in a currency other than Dollars.

     (iii) The L/C Issuer shall be under no obligation to amend any Letter of Credit if
(A) the L/C Issuer would have no obligation at such time to issue such Letter of Credit in
its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit
does not accept the proposed amendment to such Letter of Credit.

     (iv) The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of
Credit issued by it and the documents associated therewith, and the L/C Issuer shall have
all of the benefits and immunities (A) provided to the Administrative Agent in Article IX
with respect to any acts taken or omissions suffered by the L/C Issuer in connection with
Letters of Credit issued by it or proposed to be issued by it and L/C Issuer documents
pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as
used in Article IX included the L/C Issuer with respect to such acts or omissions, and (B)
as additionally provided herein with respect to the L/C Issuer.

     (b) Procedures for Issuance and Amendment of Letters of Credit; Evergreen Letters of Credit.

     (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the
request of any Borrower delivered to the L/C Issuer (with a copy to the Administrative
Agent) in the form of a Letter of Credit Application, appropriately completed and signed
by a Responsible Officer of such Borrower. Such Letter of Credit Application must be
received by the L/C Issuer and the Administrative Agent not later than noon, New York
time, at least two Business Days (or such later date and time as the L/C Issuer may agree
in a particular instance in its sole discretion) prior to the proposed issuance date or
date of amendment, as the case may be. In the case of a request for an initial issuance
of a Letter of Credit, such Letter of Credit Application shall specify in form and detail
satisfactory to the L/C Issuer: (A) the proposed issuance date of the requested Letter of
Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date
thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be
presented by such beneficiary in case of any drawing thereunder; (F) the full text of any
certificate to be presented by such beneficiary in case of any drawing thereunder; and (G)
such other matters as the L/C Issuer may require. In the case of a request for an
amendment of any outstanding Letter of Credit, such Letter of Credit Application shall
specify in form and detail satisfactory to the L/C Issuer (A) the Letter of Credit to be
amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C)
the nature of the proposed amendment; and (D) such other matters as the L/C Issuer may
require.

     (ii) Promptly after receipt of any Letter of Credit Application, the L/C Issuer will
confirm with the Administrative Agent (by telephone or in writing) that the Administrative
Agent has received a copy of such Letter of Credit Application from a Borrower and, if
not, the L/C Issuer will provide the Administrative Agent with a copy thereof. Upon
receipt by the L/C Issuer of confirmation from the Administrative Agent that the requested
issuance or amendment is permitted in accordance with the terms hereof, then, subject to
the terms and conditions hereof, the L/C Issuer shall, on the requested date, issue a
Letter of Credit for the account of such Borrower or enter into the applicable amendment,
as the case may be, in each case in accordance with the L/C Issuer’s usual and customary
business practices. Immediately upon the issuance of each Letter of Credit, each Lender
shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from
the L/C Issuer a participation in such Letter of

Borrowing Base
Credit Agreement

41

 

Credit in an amount equal to the product
of such Lender’s Pro Rata Share times the amount of such Letter of Credit.

     (iii) If a Borrower so requests in any applicable Letter of Credit Application, the
L/C Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit
that has automatic renewal provisions (each, an “Evergreen Letter of Credit”); provided
that any such Evergreen Letter of Credit must permit the L/C Issuer to prevent any such
renewal at least once in each twelve-month period (commencing with the date of issuance of
such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a
day (the “Nonrenewal Notice Date”) in each such twelve-month period to be agreed upon at
the time such Letter of Credit is issued. Unless otherwise directed by the L/C Issuer,
the Borrowers shall not be required to make a specific request to the L/C Issuer for any
such renewal. Once an Evergreen Letter of Credit has been issued, the L/C Issuer shall
permit the renewal of such Letter of Credit unless the L/C Issuer has received notice on
or before the Business Day immediately preceding the Nonrenewal Notice Date from any
Lender stating that one or more of the applicable conditions specified in Section 4.02 is
not then satisfied or the L/C Issuer would not then be required to issue a replacement
Letter of Credit pursuant to this Section 2.14.

     (iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter
of Credit to an advising bank with respect thereto or to the beneficiary thereof, the L/C
Issuer
will also deliver to the Borrowers and the Administrative Agent a true and complete
copy of such Letter of Credit or amendment.

     (c) Drawings and Reimbursements; Funding of Participations.

     (i) Upon any drawing under any Letter of Credit, the L/C Issuer shall notify the
Borrowers and the Administrative Agent thereof. Not later than noon, New York time, on
the date of any payment by the L/C Issuer under a Letter of Credit (each such date, an
“Honor Date”), the Borrowers shall reimburse the L/C Issuer through the Administrative
Agent in an amount equal to the amount of such drawing. If the Borrowers fails to so
reimburse the L/C Issuer by such time, the Administrative Agent shall promptly notify each
Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed
Amount”), and such Lender’s Pro Rata Share thereof. In such event, the Borrowers shall be
deemed to have requested a Borrowing of Base Rate Loans to be disbursed on the Honor Date
in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples
specified in Section 2.03 for the principal amount of Base Rate Loans, but subject to the
amount of the unutilized portion of the Aggregate Revolving Commitment and the conditions
set forth in Section 4.02 (other than the delivery of a Borrowing Notice) and the failure
of the Borrowers to so reimburse the Administrative Agent shall not be deemed a Default or
an Event of Default. Any notice given by the L/C Issuer or the Administrative Agent
pursuant to this Section 2.14(c)(i) may be given by telephone if immediately confirmed in
writing; provided that the lack of such an immediate confirmation shall not affect the
conclusiveness or binding effect of such notice.

     (ii) Each Lender (including the Lender acting as L/C Issuer) shall upon any notice
pursuant to Section 2.14(c)(i) make funds available to the Administrative Agent for the
account of the L/C Issuer at the Administrative Agent’s Office in an amount equal to its
Pro Rata Share of the Unreimbursed Amount not later than 11:00 a.m., New York time, on the
Business Day specified in such notice by the Administrative Agent, whereupon, subject to
the provisions of Section 2.14(c)(iii), each Lender that so makes funds available shall be
deemed to have made a

Borrowing Base
Credit Agreement

42

 

Base Rate Loan to the Borrowers in such amount. The Administrative
Agent shall remit the funds so received to the L/C Issuer.

     (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a
Borrowing of Base Rate Loans because the conditions set forth in Section 4.02 cannot be
satisfied or for any other reason, the Borrowers shall be deemed to have incurred from the
L/C Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that is not so
refinanced, which L/C Borrowing shall be due and payable on demand (together with
interest) and shall bear interest at the Default Rate. In such event, each Lender’s
payment to the Administrative Agent for the account of the L/C Issuer pursuant to Section
2.14(c)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing
and shall constitute an L/C Advance from such Lender in satisfaction of its participation
obligation under this Section 2.14.

     (iv) Until each Lender funds its Revolving Loan or L/C Advance pursuant to this
Section 2.14(c) to reimburse the L/C Issuer for any amount drawn under any Letter of
Credit, interest in respect of such Lender’s Pro Rata Share of such amount shall be solely
for the account of the L/C Issuer.

     (v) Each Lender’s obligation to make Revolving Loans or L/C Advances to reimburse the
L/C Issuer for amounts drawn under Letters of Credit, as contemplated by this Section
2.14(c), shall be absolute and unconditional and shall not be affected by any
circumstance, including (A) any set-off, counterclaim, recoupment, defense or other
right which such Lender may have against the L/C Issuer, the Borrowers or any other Person
for any reason whatsoever; (B) the occurrence or continuance of a Default or Event of
Default, or (C) any other occurrence, event or condition, whether or not similar to any of
the foregoing. Any such reimbursement shall not relieve or otherwise impair the
obligation of the Borrowers to reimburse the L/C Issuer for the amount of any payment made
by the L/C Issuer under any Letter of Credit, together with interest as provided herein.

     (vi) If any Lender fails to make available to the Administrative Agent for the
account of the L/C Issuer any amount required to be paid by such Lender pursuant to the
foregoing provisions of this Section 2.14(c) by the time specified in Section 2.14(c)(ii),
the L/C Issuer shall be entitled to recover from such Lender (acting through the
Administrative Agent), on demand, such amount with interest thereon for the period from
the date such payment is required to the date on which such payment is immediately
available to the L/C Issuer at a rate per annum equal to the Federal Funds Rate from time
to time in effect. A certificate of the L/C Issuer submitted to any Lender (through the
Administrative Agent) with respect to any amounts owing under this clause (vi) shall be
conclusive absent manifest error.

     (d) Repayment of Participations.

     (i) At any time after the L/C Issuer has made a payment under any Letter of Credit
and has received from any Lender such Lender’s L/C Advance in respect of such payment in
accordance with Section 2.14(c), if the Administrative Agent receives for the account of
the L/C Issuer any payment related to such Letter of Credit (whether directly from the
Borrowers or otherwise, including proceeds of cash Collateral applied thereto by the
Administrative Agent), or any payment of interest thereon, the Administrative Agent will
distribute to such Lender its Pro Rata Share thereof in the same funds as those received
by the Administrative Agent.

Borrowing Base
Credit Agreement

43

 

     (ii) If any payment received by the Administrative Agent for the account of the L/C
Issuer pursuant to Section 2.14(c)(i) is required to be returned, each Lender shall pay to
the Administrative Agent for the account of the L/C Issuer its Pro Rata Share thereof on
demand of the Administrative Agent, plus interest thereon from the date of such demand to
the date such amount is returned by such Lender, at a rate per annum equal to the Federal
Funds Rate from time to time in effect.

     (e) Obligations Absolute. The obligation of the Borrowers to reimburse the L/C Issuer
for each drawing under each Letter of Credit, and to repay each L/C Borrowing and each drawing
under a Letter of Credit that is refinanced by a Borrowing of Revolving Loans, shall be absolute,
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including the following:

     (i) any lack of validity or enforceability of such Letter of Credit, this Agreement,
or any other agreement or instrument relating thereto;

     (ii) the existence of any claim, counterclaim, set-off, defense or other right that
the Borrowers may have at any time against any beneficiary or any transferee of such
Letter of Credit (or any Person for whom any such beneficiary or any such transferee may
be acting), the L/C Issuer or any other Person, whether in connection with this Agreement,
the transactions contemplated hereby or by such Letter of Credit or any agreement or
instrument relating thereto, or any unrelated transaction;

     (iii) any draft, demand, certificate or other document presented under such Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any
statement therein being untrue or inaccurate in any respect; or any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under such
Letter of Credit;

     (iv) any payment by the L/C Issuer under such Letter of Credit against presentation
of a draft or certificate that does not strictly comply with the terms of such Letter of
Credit; or any payment made by the L/C Issuer under such Letter of Credit to any Person
purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit
of creditors, liquidator, receiver or other representative of or successor to any
beneficiary or any transferee of such Letter of Credit, including any arising in
connection with any proceeding under any Debtor Relief Law; or

     (v) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, that might otherwise constitute a defense available to, or a discharge of,
the Borrowers.

     The relevant Borrower requesting a Letter of Credit shall promptly examine a copy of each
Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim
of noncompliance with such Borrowers’ instructions or other irregularity, such Borrower will
immediately notify the L/C Issuer. The Borrowers shall be conclusively deemed to have waived any
such claim against the L/C Issuer and its correspondents unless such notice is given as aforesaid.

     (f) Role of L/C Issuer. Each Lender and the Borrowers agree that, in paying any
drawing under a Letter of Credit, the L/C Issuer shall not have any responsibility to obtain any
document (other than any sight draft, certificates and documents expressly required by the Letter
of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the
authority of the Person executing or delivering any such document. No Agent-Related Person nor any
of the respective correspondents,

Credit Agreement

44

 

Participants or assignees of the L/C Issuer shall be liable to
any Lender for (i) any action taken or omitted in connection herewith at the request or with the
approval of the Lenders or the Required Lenders, as applicable, (ii) any action taken or omitted in
the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness,
validity or enforceability of any document or instrument related to any Letter of Credit or Letter
of Credit Application. The Borrowers hereby assume all risks of the acts or omissions of any
beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that
this assumption is not intended to, and shall not, preclude the Borrowers’ pursuing such rights and
remedies as it may have against the beneficiary or transferee at law or under any other agreement.
No Agent-Related Person, nor any of the respective correspondents, Participants or assignees of the
L/C Issuer, shall be liable or responsible for any of the matters described in clauses (i) through
(v) of Section 2.14(e); provided, however, that anything in such clauses to the contrary
notwithstanding, the Borrowers may have a claim against the L/C Issuer, and the L/C Issuer may be
liable to the Borrowers, to the extent, but only to the extent, of any direct, as opposed to
consequential or exemplary, damages suffered by the Borrowers which the Borrowers prove were caused
by the L/C Issuer’s willful misconduct or gross negligence or the L/C Issuer’s willful failure to
pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and
certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In
furtherance and not in limitation of the foregoing, the L/C Issuer may accept documents that appear
on their face to be in order, without responsibility for further investigation, regardless of any
notice or information to the contrary, and the L/C Issuer shall not be responsible for the validity
or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part,
which may prove to be invalid or ineffective for any reason.

     (g) Cash Collateral. Upon the request of the Administrative Agent, (i) if the L/C
Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing
has resulted in an L/C Borrowing, or (ii) if, as of the Letter of Credit Expiration Date, any
Letter of Credit may for any reason remain outstanding and partially or wholly undrawn, the
Borrowers shall immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations
(in an amount equal to such Outstanding Amount). The Borrowers hereby grant the Administrative
Agent, for the benefit of the L/C Issuer and the Lenders, a Lien on all such cash and deposit
accounts at any Lender.

     (h) Applicability of ISP98. Unless otherwise expressly agreed by the L/C Issuer and
the relevant Borrower requesting a Letter of Credit when a Letter of Credit is issued, the rules of
the “International Standby Practices 1998” published by the Institute of International Banking Law
& Practice (or such later version thereof as may be in effect at the time of issuance) shall apply
to each Letter of Credit.

     (i) Letter of Credit Fees. The Borrowers shall pay to the Administrative Agent for
the account of each Lender in accordance with its Pro Rata Share a Letter of Credit fee for each
Letter of Credit issued equal to the Applicable Rate times the actual daily undrawn amount under
each Letter of Credit. Such fee for each Letter of Credit shall be due and payable on the last
Business Day of each March, June, September and December, commencing with the first such date to
occur after the issuance of such Letter of Credit, and on the Letter of Credit Expiration Date. If
there is any change in the Applicable Rate during any quarter, the actual amount of each Letter of
Credit shall be computed and multiplied by the Applicable Rate separately for each period during
such quarter that such Applicable Rate was in effect.

     (j) Fronting Fee and Documentary and Processing Charges Payable to L/C Issuer. The
Borrowers shall pay directly to the L/C Issuer for its own account a fronting fee in an amount with
respect to each Letter of Credit issued equal to the greater of (i) $500 and (ii) 1/4 of 1% (25 Basis
Points) calculated on the face amount thereof. In addition, the Borrowers shall pay directly to
the L/C Issuer for

Credit Agreement

45

 

its own account the customary issuance, presentation, amendment and other
processing fees, and other standard costs and charges, of the L/C Issuer relating to letters of
credit as from time to time in effect. Such fees and charges are due and payable on demand and are
nonrefundable.

     (k) Conflict with Letter of Credit Application. In the event of any conflict between
the terms hereof and the terms of any Letter of Credit Application, the terms hereof shall control.

     (l) Letters of Credit Issued for the Borrowers. Notwithstanding that a Letter of
Credit issued or outstanding hereunder is in support of any obligations of, or is for the account
of, a Borrower or any of its Subsidiaries (other than the Excluded Subsidiaries), the Borrowers
shall be jointly and severally obligated to reimburse the L/C Issuer hereunder for any and all
drawings under such Letter of Credit. Each Borrower hereby acknowledges that the issuance of
Letters of Credit in support of any obligation of, or for the account of the other Borrower or any
of such other Borrower’s Subsidiaries (other than the Excluded Subsidiaries) inures to the benefit
of both Borrowers, and that each other Borrower’s business derives substantial benefits from the
businesses of the other Borrower and its Subsidiaries (other than the Excluded Subsidiaries).

ARTICLE III. TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01. Taxes.

     (a) Any and all payments by the Borrowers to or for the account of the Administrative Agent or
any Lender under any Loan Document shall be made free and clear of and without deduction for any
and all present or future taxes, duties, levies, imposts, deductions, assessments, fees,
withholdings or similar charges, and all liabilities with respect thereto; excluding, in the case
of the Administrative Agent and each Lender, taxes imposed on or measured by its net income
(including any franchise taxes imposed on or measured by its net income), by the jurisdiction (or
any political subdivision thereof) under the Laws of which the Administrative Agent or such Lender,
as the case may be, is organized or maintains its Lending Office (all such non-excluded taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar charges, and
liabilities being hereinafter referred to as “Taxes”). If the Borrowers shall be required by any
Laws to deduct any Taxes from or in respect of any sum payable under any Loan Document to the
Administrative Agent or any Lender, (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), each of the Administrative Agent and such Lender receives an amount equal to
the sum it would have received had no such deductions been made, (ii) the Borrowers shall make such
deductions and (iii) the Borrowers shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable Laws.

     (b) In addition, the Borrowers agree to pay any and all present or future stamp, mortgage,
court or documentary taxes and any other excise or property taxes or charges or similar levies
which arise from any payment made under any Loan Document or from the execution, delivery,
performance, enforcement or registration of, or otherwise with respect to, any Loan Document
(hereinafter referred to as “Other Taxes”).

     (c) If the Borrowers shall be required to deduct or pay any Taxes or Other Taxes from or in
respect of any sum payable under any Loan Document to the Administrative Agent or any Lender, the
Borrowers shall also pay to the Administrative Agent (for the account of such Lender) or to such
Lender, at the time interest is paid, such additional amount that such Lender specifies as
necessary to preserve the after-tax yield (after factoring in all taxes, including taxes imposed on
or measured by net income) such Lender would have received if such Taxes or Other Taxes had not
been imposed.

Credit Agreement

46

 

     (d) The Borrowers agree to indemnify the Administrative Agent and each Lender for (i) the full
amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed or asserted by any
jurisdiction on amounts payable under this Section) paid by the Administrative Agent and such
Lender, and (ii) amounts payable under Section 3.01(c) and (iii) any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto, except to the extent
such sums are determined by a court of competent jurisdiction by final and non-appealable judgment
to have resulted from the gross negligence or willful misconduct of the Administrative Agent, the
L/C Issuer or such Lender, as applicable. Neither the Administrative Agent, the L/C Issuer nor any
Lender shall be entitled to receive any payment with respect to any indemnity claim under this
Section 3.01 with respect to Taxes or Other Taxes that are incurred or accrued more than 180 days
prior to the date such party gives notice and demand with respect thereto to the Borrowers.
Payment under this subsection (d) shall be made within 30 days after the date the Lender or the
Administrative Agent makes a demand therefor.

     (e) As soon as practicable after any payment of indemnified Taxes or Other Taxes by the
Borrowers to a Governmental Authority, the Borrowers shall deliver to the Administrative Agent the
original or a certified copy of a receipt issued by such Governmental Authority evidencing
such payment, a copy of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Administrative Agent.

     (f) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax
under the Law of the jurisdiction in which any Borrower is resident for tax purposes, or any treaty
to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan
Document shall deliver to the Borrowers (with a copy to the Administrative Agent), at the time or
times prescribed by applicable Law or reasonably requested by the Borrowers or the Administrative
Agent, such properly completed and executed documentation prescribed by applicable Law, or
reasonably requested by Borrowers, as will permit such payments to be made without withholding or
at a reduced rate of withholding. In addition, any Lender, if requested by the Borrowers or the
Administrative Agent, shall deliver such other documentation prescribed by applicable Law or
reasonably requested by the Borrowers or the Administrative Agent as will enable the Borrowers or
the Administrative Agent to determine whether or not such Lender is subject to backup withholding
or information reporting requirements.

     Without limiting the generality of the foregoing, in the event that any Borrower is resident
for tax purposes in the United States, any Foreign Lender shall deliver to the Borrowers and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior
to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to
time thereafter upon the request of the Borrowers or the Administrative Agent, but only if such
Foreign Lender is legally entitled to do so), whichever of the following is applicable:

     (i) duly completed copies of Internal Revenue Service Form W-8BEN claiming
eligibility for benefits of an income tax treaty to which the United States is a party;

     (ii) duly completed copies of Internal Revenue Service Form W-8ECI;

     (iii) in the case of a Foreign Lender claiming the benefits of the exemption for
portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that
such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the
Code, (B) a “10 percent shareholder” of any Borrower within the meaning of section
881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section
881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form
W-8BEN; or

Credit Agreement

47

 

     (iv) any other form prescribed by applicable Law as a basis for claiming exemption
from or a reduction in United States Federal withholding tax duly completed together with
such supplementary documentation as may be prescribed by applicable Law to permit the
Borrowers to determine the withholding or deduction required to be made.

     (g) If the Administrative Agent, any Lender or the L/C Issuer determines, in its sole
discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been
indemnified by the Borrowers or with respect to which the Borrowers have paid additional amounts
pursuant to this Section, it shall pay to the Borrowers an amount equal to such refund (but only to
the extent of indemnity payments made, or additional amounts paid, by the Borrowers under this
Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of the Administrative Agent, such Lender or the L/C Issuer, as the case may
be, and without interest (other than any interest paid by the relevant Governmental Authority with
respect to such refund); provided that the Borrowers, upon the request of the Administrative Agent,
such Lender or the L/C Issuer, agrees to repay the amount paid over to the Borrowers (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority) to the
Administrative Agent, such Lender or the L/C Issuer in the event the
Administrative Agent, such Lender or the L/C Issuer is required to repay such refund to such
Governmental Authority. This subsection shall not be construed to require the Administrative
Agent, any Lender or the L/C Issuer to make available its tax returns (or any other information
relating to its taxes that it deems confidential) to the Borrowers or any other Person.

     3.02. Illegality. If any Lender determines that any Change in Law has made it unlawful for any
Lender or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans, or
materially restricts the authority of such Lender to purchase or sell, or to take deposits of,
Dollars in the applicable offshore Dollar market, or to determine or charge interest rates based
upon the Eurodollar Rate, then, on notice thereof by such Lender to the Borrowers through the
Administrative Agent, any obligation of such Lender to make or continue Eurodollar Rate Loans or to
convert Base Rate Loans to Eurodollar Rate Loans shall be suspended until such Lender notifies the
Administrative Agent and the Borrowers that the circumstances giving rise to such determination no
longer exist. Upon receipt of such notice, the Borrowers shall, upon demand from such Lender (with
a copy to the Administrative Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of
such Lender to Base Rate Loans, either on the last day of the Interest Period thereof, if such
Lender may lawfully continue to maintain such Eurodollar Rate Loans to such day, or immediately, if
such Lender may not lawfully continue to maintain such Eurodollar Rate Loans. Upon any such
prepayment or conversion, the Borrowers shall also pay interest on the amount so prepaid or
converted and all amounts due under Section 3.05 in accordance with the terms thereof due to such
prepayment or conversion. Each Lender agrees to designate a different Lending Office if such
designation will avoid the need for such notice and will not, in the reasonable judgment of such
Lender, otherwise be materially disadvantageous to such Lender.

     3.03. Inability to Determine Rates. If (a) the Administrative Agent (or any Lender) determines in
connection with any request for a Eurodollar Rate Loan or a conversion to or continuation thereof
that Dollar deposits are not being offered to banks (or such Lender) in the applicable offshore
Dollar market for the applicable amount and Interest Period of such Eurodollar Rate Loan, or
adequate and reasonable means do not exist for determining the Eurodollar Rate for such Eurodollar
Rate Loan, or (b) the Required Lenders (or any Lender) determine and notify the Administrative
Agent that the Eurodollar Rate for such Eurodollar Rate Loan does not adequately and fairly reflect
the cost to the Lenders (or such Lender) of funding such Eurodollar Rate Loan, then the
Administrative Agent will promptly notify the Borrowers and all Lenders. Thereafter, the
obligation of the Lenders to make or maintain Eurodollar Rate Loans shall be suspended until all of
the Lenders agree the conditions specified in clauses (a) or (b) above no longer exist, whereupon
the Administrative Agent shall revoke such notice. Upon receipt of such notice, the Borrowers may
revoke any pending request for a Borrowing, conversion

Borrowing Base
Credit Agreement

48

 

or continuation of Eurodollar Rate Loans or,
failing that, will be deemed to have converted such request into a request for a Borrowing of Base
Rate Loans in the amount specified therein.

     3.04. Increased Cost and Reduced Return; Capital Adequacy; Reserves on Eurodollar Rate Loans.

     (a) If any Lender or the L/C Issuer determines that as a result of a Change in Law, or such
Lender’s or L/C Issuer’s compliance therewith, there shall be any increase in the cost to such
Lender or L/C Issuer of agreeing to make or making, funding or maintaining Eurodollar Rate Loans or
to increase the cost to such Lender or the L/C Issuer of participating in, issuing or maintaining
any Letter of Credit,
or a reduction in the amount received or receivable by such Lender or L/C Issuer in connection
with any of the foregoing (excluding for purposes of this subsection (a) any such increased costs
or reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section 3.01 shall
govern), (ii) changes in the basis of taxation of overall net income or overall gross income by the
United States or any foreign jurisdiction or any political subdivision of either thereof under the
Laws of which such Lender or L/C Issuer is organized or has its Lending Office, and (iii) reserve
requirements contemplated by Section 3.04(c) utilized, as to Eurodollar Rate Loans, in the
determination of the Eurodollar Rate), then from time to time upon demand of such Lender or L/C
Issuer (with a copy of such demand to the Administrative Agent), the Borrowers shall pay to such
Lender or L/C Issuer, as the case may be, such additional amounts as will compensate such Lender or
L/C Issuer for such increased cost or reduction.

     (b) If any Lender determines a Change in Law has the effect of reducing the rate of return on
the capital of such Lender or any corporation controlling such Lender as a consequence of such
Lender’s obligations hereunder (taking into consideration its policies with respect to capital
adequacy and such Lender’s desired return on capital), then from time to time upon demand of such
Lender (with a copy of such demand to the Administrative Agent), the Borrowers shall pay to such
Lender such additional amounts as will compensate such Lender for such reduction.

     (c) The Borrowers shall pay to each Lender, as long as such Lender shall be required under
regulations of the Board to maintain reserves with respect to liabilities or assets consisting of
or including Eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”),
additional costs on the unpaid principal amount of each Eurodollar Rate Loan equal to the actual
costs of such reserves allocated to such Revolving Loan by such Lender (as determined by such
Lender in good faith, which determination shall be conclusive), which shall be due and payable on
each date on which interest is payable on such Revolving Loan; provided the Borrowers shall have
received at least 15 days’ prior notice (with a copy to the Administrative Agent) of such
additional interest from such Lender. If a Lender fails to give notice 15 days prior to the
relevant Interest Payment Date, such additional interest shall be due and payable 15 days from
receipt of such notice.

     (d) Failure or delay on the part of any Lender or the L/C Issuer to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender’s or the L/C Issuer’s right
to demand such compensation; provided that the Borrowers shall not be required to compensate a
Lender or the L/C Issuer pursuant to this Section for any increased costs or reductions incurred
more than 180 days prior to the date that such Lender or the L/C Issuer, as the case may be,
notifies the Borrowers of the Change in Law giving rise to such increased costs or reductions and
of such Lender’s or the L/C Issuer’s intention to claim compensation therefor; provided further
that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then
the 180-day period referred to above shall be extended to include the period of retroactive effect
thereof.

Credit Agreement

     3.05. Compensation for Losses. Upon demand of any Lender (with a copy to the Administrative Agent)
from time to time, the Borrowers shall promptly compensate such Lender for and hold such Lender
harmless from any loss, cost or expense incurred by it as a result of:

     (a) any assignment pursuant to Section 10.15 (except pursuant to clause (iii) and clause (iv)
of the second sentence in Section 10.15, to the extent clause (iv) includes clause (iii)) or any
continuation, conversion, payment, prepayment of any Revolving Loan other than a Base Rate Loan on
a day other than the last day of the Interest Period for such Revolving Loan (whether voluntary,
mandatory, automatic, by reason of acceleration, or otherwise); or

     (b) any failure by the Borrowers (for a reason other than the failure of such Lender to make a
Revolving Loan) to prepay, borrow, continue or convert any Revolving Loan other than a Base Rate
Loan on the date or in the amount notified by the Borrowers; including any loss of anticipated
profits and any loss or expense arising from the liquidation or reemployment of funds obtained by
it to maintain such Revolving Loan or from fees payable to terminate the deposits from which such
funds were obtained. The Borrowers shall also pay any customary administrative fees charged by
such Lender in connection with the foregoing.

     For purposes of calculating amounts payable by the Borrowers to the Lenders under this Section
3.05, each Lender shall be deemed to have funded each Eurodollar Rate Loan made by it at the
Eurodollar Rate for such Revolving Loan by a matching deposit or other borrowing in the applicable
offshore Dollar interbank market for a comparable amount and for a comparable period, whether or
not such Eurodollar Rate Loan was in fact so funded.

     3.06. Matters Applicable to all Requests for Compensation. A certificate of the Administrative
Agent or any Lender claiming compensation under this Article III and setting forth the additional
amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error.
In determining such amount, the Administrative Agent or such Lender may use any reasonable
averaging and attribution methods.

     3.07. Survival. All of the Borrowers’ obligations under this Article III shall survive termination
of the Aggregate Revolving Commitment and payment in full of all the other Obligations.

     3.08. Mitigation Obligations. If any Lender or L/C Issuer requests compensation under Section
3.04, or if the Borrowers are required to pay any additional amount to any Lender, L/C Issuer or
any Governmental Authority for the account of any Lender or L/C Issuer, as applicable, pursuant to
Section 3.01, then such Lender or L/C Issuer shall use reasonable efforts to designate a different
lending office for funding or booking its Revolving Loans or issuing Letters of Credit hereunder or
to assign its rights and obligations hereunder to another of its offices, branches or affiliates,
if, in the judgment of such Lender or L/C Issuer, such designation or assignment (i) would
eliminate or reduce amounts payable pursuant to Section 3.01 or Section 3.04, as the case may be,
in the future and (ii) would not subject such Lender or L/C Issuer to any un-reimbursed cost or
expense and would not otherwise be disadvantageous to such Lender or L/C Issuer. The Borrowers
hereby agree to pay all reasonable costs and expenses incurred by any Lender or L/C Issuer in
connection with any such designation or assignment.

excessive in relation to the value of the security to be afforded thereby; provided, that with
respect to rights of way, easements, leases or other similar property interests acquired by any
Loan Party after the date hereof relating to the Bluestem Gathering System now owned by

authorization, opinions of counsel, current valuations, evidence of title, and other documents, and
shall use commercially reasonable efforts to obtain third party consents, as shall be reasonably
requested by the Administrative Agent, in each case in form and substance reasonably satisfactory
to the Administrative Agent.

     (c) Except for the second priority Liens in favor of the Administrative or Collateral Agent
for the benefit of the Lenders on the KPC Pipeline, the Liens required by this Section 6.15 shall
be first priority Liens in favor of the Administrative Agent or Collateral Agent for the benefit of
the Secured Parties, subject to no other Liens except Permitted Liens of the type described in
Section 7.01. The Liens required by this Section 6.15 shall be perfected Liens in favor of the
Administrative Agent or Collateral Agent for the benefit of the Secured Parties in all collateral

statement in the relevant jurisdiction, (ii) filing or recording a mortgage in real property

form and substance reasonably satisfactory to the
Administrative Agent) such that the Administrative Agent shall have received currently
effective duly executed and perfected Collateral Documents encumbering substantially all of the
assets of the Borrowers and their respective Subsidiaries (other than the Excluded Subsidiaries)
as required by Section 6.15(a).

     (d) If an Event of Default exists and is continuing, the Borrowers agree to deliver and to
cause each other Loan Party to deliver, whenever requested by Administrative Agent, in its sole and
absolute discretion, transfer orders or letters in lieu thereof with respect to the production and
proceeds of production from the Borrowing Base Oil and Gas Properties, in form and substance
satisfactory to Administrative Agent.

     6.16. Title Defects. Cure any title defects to the Borrowing Base Oil and Gas Properties material
in value, in the reasonable opinion of the Administrative Agent, within ninety days after receipt
of written notice thereof from Administrative Agent and, in the event any title defects are not
cured in a timely manner, pay all related costs and fees reasonably incurred by the Administrative
Agent for the account of the Lenders to do so; provided the Borrowers may remove any of its Oil and
Gas Properties from the Borrowing Base Oil and Gas Properties so long as the Indebtedness evidenced
by the Revolving Notes is less than or equal to the Borrowing Base (determined by the Lenders in
accordance with Section 2.02 exclusive of such Oil and Gas Properties). In the event that the
Borrowers are unable to cure a title defect, the Borrowers shall have the ability to substitute
additional collateral; provided that the Borrowers’ ability to substitute such collateral is
subject to the full satisfaction of the Administrative Agent, including, without limitation in full
compliance with the requirements described in Section 2.02. Furthermore, after identification and
prior to the cure of any such title defect, the Administrative Agent may, subject to approval of
the Required Lenders, and must, upon the request of the Required Lenders, redetermine the Borrowing
Base to reflect the amount of such title defect.

     6.17. Leases. Keep and continue all material Leases comprising the Borrowing Base Oil and Gas
Properties and related contracts and agreements relating thereto in full force and effect in
accordance with the terms thereof and not permit the same to lapse or otherwise become impaired for
failure to comply with the obligations thereof, whether express or implied; provided, however, that
this provision shall not prevent the Borrowers or any other Loan Party from abandoning and
releasing any such Leases upon their termination as the result of cessation of production in paying
quantities that did not result from any Borrower’s’ or any other Loan Party’s failure to maintain
such production as a reasonably prudent operator. Subject to approval by the Administrative Agent,
the Borrowers and each Loan Party shall have the right to replace Leases that lapse or become
impaired.

     6.18. Operation of Borrowing Base Oil and Gas Properties. Operate or, to the extent that the right
of operation is vested in others, exercise all reasonable efforts to require the operator to
operate the Borrowing Base Oil and Gas Properties and all wells drilled thereon and that may
hereafter be drilled thereon, continuously and in a prudent and workmanlike manner and in
accordance with all Laws of the state in which the Borrowing Base Oil and Gas Properties are
situated and the United States, as well as all rules, regulations, and Laws of any Governmental
Authority having jurisdiction to regulate the manner in which the operation of the Borrowing Base
Oil and Gas Properties shall be carried on, and comply with all terms and conditions of the Leases
it now holds, and any assignment or contract obligating any Borrower or any other Loan Party in any
way with respect to the Borrowing Base Oil and Gas Properties, except for any such non-compliance
that would not have a Material Adverse Effect; but nothing herein shall be construed to empower any
Borrower to bind the
Administrative Agent or any Lender to any contract obligation, or render the Administrative Agent
or any Lender in any way responsible or liable for bills or obligations incurred by any Borrower or
any other Loan Party.

     6.19. Change of Purchasers of Production. Concurrently with the delivery of (and as part of) the
annual Compliance Certificate, and at any other time that the Administrative Agent may reasonably
request in writing, the Borrowers shall notify the Administrative Agent in writing of the identity
and address of each Person who: (a) has purchased any of any Borrower’s or any other Loan Party’s
interests in oil and gas produced from the Borrowing Base Oil and Gas Properties during the six
calendar months preceding such anniversary of the Closing, and (b) are considered by Borrowers or
another Loan Party to

Borrowing Base
Credit Agreement

66

 

be potential future purchasers of any Borrower’s or any other Loan Party’s
interest in oil and gas produced from the Borrowing Base Oil and Gas Properties.

     6.20. Fiscal Year. The Borrowers shall maintain its December 31 fiscal year end.

     6.21. Liens on Oil and Gas Properties; Title Information. (a) At all times have granted in favor
of the Administrative Agent for the benefit of the Lenders as security for the Obligations first
priority perfected Liens on no less than ninety percent (90%) of PV10 of the Proved Reserves that
are attributable to the Borrowing Base Oil and Gas Properties.

     (b) On or before the delivery to the Administrative Agent of each Reserve Report required by
Sections 2.02(c) and (d), the Borrowers will deliver (or have previously delivered to the
Administrative Agent) title information in form and substance acceptable to the Administrative
Agent comprising a minimum of eighty percent (80%) of the PV10 (based on the most recent Borrowing
Base evaluation by the Administrative Agent) of the Proved Reserves that are attributable to those
Borrowing Base Oil and Gas Properties evaluated by such Reserve Report (it being acknowledged that
landman title reports on proved but undeveloped Oil and Gas Properties shall be satisfactory to the
Administrative Agent and Lenders for the purpose of demonstrating the status of title to such Oil
and Gas Properties).

     6.22. Capital Expenditures. The Borrowers shall make minimum Capital Expenditures in the
cumulative aggregate amount of (i) $5.0 million for the six-month period ending December 31, 2010,
(ii) $10.0 million for the nine-month period ending March 31, 2011, (iii) $17.5 million for the
twelve-month period ending June 30, 2011, and (iv) $25.0 million for the fifteen-month period
ending September 30, 2011; provided however that if, in the time period described in clause (i),
the Borrowers (or any one or more of them) have not expended the minimum aggregate Capital
Expenditure amount required to be expended by December 31, 2010, the Borrowers shall be entitled to
an additional quarter to expend such amount, as long as by the end of the quarter ended March 31,
2011, $10.0 million in aggregate minimum Capital Expenditures has been expended. In the event the
Borrowers have not expended the minimum aggregate Capital Expenditure amount required to be
expended by March 31, 2011, June 30, 2011 or September 30, 2011, the sole result shall be a
reduction in the Borrowing Base by an amount equal to the shortfall, and Borrowers’ failure to
expend the required minimum Capital Expenditures amount shall not constitute a Default or an Event
of Default under this Agreement.

after the first day of such Reference Period any Borrower or its consolidated Subsidiary (other
than the Excluded Subsidiaries) shall have made any Material Disposition, the Adjusted Consolidated
EBITDA for such Reference Period shall be reduced by an amount equal to the Adjusted Consolidated
EBITDA (if positive) attributable to the Oil and Gas Property or other Collateral that is the
subject of such Material Disposition for such Reference Period. Except as otherwise indicated, the
ratios set out above shall be calculated at the end of each reporting period for which this
Agreement requires Borrowers to deliver financial statements pursuant to Sections 6.01(a) and (b),
using the results of the twelve-month period ending with that reporting period.

forma basis (in a manner reasonably acceptable to the Administrative Agent) for the four
consecutive fiscal quarters most recently completed, to any Permitted Acquisition or
Material Acquisition occurring during such period, as if such Permitted Acquisition or
Material Acquisition occurred on the first day of such period.

     (ii) If, in connection with a Permitted Acquisition or a Material Acquisition, any
Indebtedness is incurred or assumed by a Company, then Consolidated Interest Charges shall
be calculated, on a pro forma basis (in a manner reasonably acceptable to the
Administrative Agent) for the four quarters most recently completed, as if such
Indebtedness had been incurred on the first day of such period.

of the L/C Issuer to make L/C Credit Extensions to be terminated, whereupon such Revolving
Commitments and obligations shall be terminated;

     (b) declare the unpaid principal amount of all outstanding Revolving Loans, all interest
accrued and unpaid thereon, and all other amounts owing or payable hereunder or under any other
Loan Document to be immediately due and payable, without presentment, demand, protest, notice of
intent to accelerate, notice of acceleration or other notice of any kind, all of which are hereby
expressly waived by the Borrowers;

     (c) declare that an amount equal to the then Outstanding Amount of all L/C Obligations be
immediately due and payable by the Borrowers, without presentment, demand, protest, notice of
intent to accelerate, notice of acceleration or other notice of any kind, all of which are hereby

the Lenders under the Loan Documents or applicable Law;

provided, however, that upon the occurrence of any event specified in subsection (f) of Section

make L/C Credit Extensions shall automatically terminate, the unpaid principal amount of all
outstanding Revolving Loans and all interest and other amounts as aforesaid shall automatically
become due and payable, and an amount equal to the then Outstanding Amount of all L/C Obligations
shall be deemed to be forthwith due and owing by the Borrowers to the L/C Issuer and the Lenders as
of the date of such occurrence and the Borrowers’ obligation to pay such amounts shall be absolute
and unconditional, without regard to whether any beneficiary of any such Letter of Credit has
attempted to draw down all or a portion of such amount under the terms of a Letter of Credit and,
to the fullest extent permitted by applicable Law, shall not be subject to any defense or be
affected by a right of set-off, counterclaim or recoupment which the Borrowers may now or hereafter
have against any such beneficiary, the L/C Issuer, the Administrative Agent, the Lenders or any
other Person for any reason whatsoever. Such payments shall be delivered to and held by the
Administrative Agent as cash collateral securing the L/C Obligations.

     8.03. Application of Funds. After the exercise of remedies provided for in Section 8.02 (or after
the Revolving Loans have automatically become immediately due and payable and the L/C Obligations

8.02), any amounts received on account of the Obligations shall be applied by the Administrative
Agent as set forth in Section 2.11(d).

ARTICLE IX.

ADMINISTRATIVE AGENT

     9.01. Appointment and Authorization of Agents; Lender Hedging Agreements. (a) Each Lender hereby
irrevocably (subject to Section 9.10) appoints, designates and authorizes the Administrative Agent
to take such action on its behalf under the provisions of this Agreement and each other Loan
Document and to exercise such powers and perform such duties as are expressly delegated to it by
the terms of this Agreement or any other Loan Document, together with such powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in
any other Loan Document, the Administrative Agent shall not have any duties or responsibilities,
except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to
have any fiduciary relationship with any Lender or Participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement
or any other Loan Document or otherwise exist against the Administrative Agent. Without limiting
the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan
Documents with reference to the Administrative Agent or Collateral Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency doctrine of any
applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to
create or reflect only an administrative relationship between independent contracting parties.

     (b) The L/C Issuer shall act on behalf of the Lenders with respect to any Letters of Credit
issued by it and the documents associated therewith until such time (and except for so long) as the
Administrative Agent may agree at the request of the Required Lenders to act for the L/C Issuer
with respect thereto; provided, however, that the L/C Issuer shall have all of the benefits and
immunities (i) provided to the Administrative Agent in this Article IX with respect to any acts
taken or omissions suffered by the L/C Issuer in connection with Letters of Credit issued by it or
proposed to be issued by it and the application and agreements for letters of credit pertaining to
the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article IX
included the L/C Issuer with respect to such acts or omissions, and (ii) as additionally provided
herein with respect to the L/C Issuer.

     (c) To the extent any Lender or any Affiliate of a Lender is a party to a Lender Hedging
Agreement and accepts the benefits of the Liens in the Collateral arising pursuant to the
Collateral Documents, such Lender (for itself and on behalf of any such Affiliates) shall be deemed
(i) to appoint the Administrative Agent and Collateral Agent, as its nominee and agent, to act for
and on behalf of such Lender or Affiliate thereof in connection with the Collateral Documents and
(ii) to be bound by the terms of this Article IX.

     9.02. Delegation of Duties. The Administrative Agent may execute any of its duties under this
Agreement or any other Loan Document by or through agents (including the Collateral Agent),
employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or
experts concerning all matters pertaining to such duties. Neither the Administrative Agent nor
Collateral Agent shall be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects in the absence of gross negligence or willful misconduct.

     9.03. Default; Collateral. (a) Upon the occurrence and continuance of a Default or Event of
Default, the Lenders agree to promptly confer in order that Required Lenders or the Lenders, as the
case may be, may agree upon a
course of action for the enforcement of the rights of the Lenders; and the Administrative Agent
shall be entitled to refrain from taking any action (without incurring any liability to any Person
for so refraining) unless and until the Administrative Agent shall have received instructions from
Required Lenders. All rights of action under the Loan Documents and all right to the Collateral,
if any, hereunder may be enforced by the Administrative Agent (or Collateral Agent) and any suit or

Borrowing Base
Credit Agreement

82

 

proceeding instituted by the Administrative Agent (or Collateral Agent) in furtherance of such
enforcement shall be brought in its name as the Administrative Agent (or Collateral Agent) without
the necessity of joining as plaintiffs or defendants any other Lender, and the recovery of any
judgment shall be for the benefit of the Lenders (and, with respect to Lender Hedging Agreements,
Affiliates, if applicable) subject to the expenses of the Administrative Agent and Collateral
Agent. In actions with respect to any property of the Borrowers or any other Obligor, the
Administrative Agent (and the Collateral Agent) is acting for the ratable benefit of each Lender
(and, with respect to Lender Hedging Agreement, Affiliates, if applicable). Any and all agreements
to subordinate (whether made heretofore or hereafter) other indebtedness or obligations of
Borrowers to the Obligations shall be construed as being for the ratable benefit of each Lender
(and, with respect to Lender Hedging Agreement, Affiliates, if applicable).

     (b) Each Lender authorizes and directs the Administrative Agent and the Collateral Agent to
enter into the Collateral Documents on behalf of and for the benefit of the Lenders (and, with
respect to Lender Hedging Agreements, Affiliates, if applicable)(or if previously entered into,
hereby ratifies the Administrative Agent’s and Collateral Agent’s previously entering into such
agreements and Collateral Documents).

     (c) Except to the extent unanimity (or other percentage set forth in Section 10.01) is
required hereunder, each Lender agrees that any action taken by the Required Lenders in accordance
with the provisions of the Loan Documents, and the exercise by the Required Lenders of the power
set forth herein or therein, together with such other powers as are reasonably incidental thereto,
shall be authorized and binding upon all of the Lenders.

     (d) The Administrative Agent and Collateral Agent are each hereby authorized on behalf of the
Lenders, without the necessity of any notice to or further consent from any Lender, from time to
time to take any action with respect to any Collateral or Collateral Documents which may be
necessary to perfect and maintain perfected the Liens upon the Collateral granted pursuant to the
Collateral Documents.

     (e) Neither the Administrative Agent nor the Collateral Agent shall have any obligation
whatsoever to any Lender or to any other Person to assure that the Collateral exists or is owned by
any Obligor or is cared for, protected, or insured or has been encumbered or that the Liens granted
to the Administrative Agent and/or Collateral Agent herein or pursuant thereto have been properly
or sufficiently or lawfully created, perfected, protected, or enforced, or are entitled to any
particular priority, or to exercise at all or in any particular manner or under any duty of care,
disclosure, or fidelity, or to continue exercising, any of the Rights granted or available to the
Administrative Agent or Collateral Agent in this Section 9.03 or in any of the Collateral
Documents; it being understood and agreed that in respect of the Collateral, or any act, omission,
or event related thereto, the Administrative Agent may act in any manner it may deem appropriate,
in its sole discretion, given the Administrative Agent’s own interest in the Collateral as one of
the Lenders and that the Administrative Agent shall have no duty or liability whatsoever to any
Lender, other than to act without gross negligence or willful misconduct and the same shall apply
to the Collateral Agent so long as the Administrative Agent is also the Collateral Agent.

     (f) The Lenders hereby irrevocably authorize the Administrative Agent and/or Collateral Agent,
at its option and in its discretion, to release any Lien granted to or held by the Administrative
Agent or Collateral Agent upon any Collateral: (i) constituting property in which no Obligor
owned an interest at the time the Lien was granted or at any time thereafter; (ii) constituting
property leased or granted to an Obligor under a lease, easement or right-of-way which has expired
or been terminated in a transaction permitted under the Loan Documents or is about to expire and
which has not been, and is not

Borrowing Base
Credit Agreement

83

 

intended by such Obligor to be, renewed; and (iii) consisting of an
instrument evidencing Indebtedness pledged to the Administrative Agent or Collateral Agent (for the
benefit of the Lenders), if the Indebtedness evidenced thereby has been paid in full. In addition,
the Lenders irrevocably authorize the Administrative Agent and Collateral Agent to release Liens
upon Collateral as contemplated in Section 10.01(c) or (d), or if approved, authorized, or ratified
in writing by the requisite Lenders. Upon request by the Administrative Agent (or Collateral
Agent) at any time, the Lenders will confirm in writing the Administrative Agent’s (or Collateral
Agent’s) authority to release particular types or items of Collateral pursuant to this Section
9.03.

     (g) In furtherance of the authorizations set forth in this Section 9.03, each Lender hereby
irrevocably appoints the Administrative Agent and Collateral Agent its attorney-in-fact, with full
power of substitution, for and on behalf of and in the name of each such Lender (i) to enter into
Collateral Documents (including, without limitation, any appointments of substitute trustees under
any Collateral Documents and any appointment of a collateral agent under the Intercreditor
Agreement), (ii) to take action with respect to the Collateral and Collateral Documents to perfect,
maintain, and preserve Lenders’ Liens, and (iii) to execute instruments of release or to take other
action necessary to release Liens upon any Collateral to the extent authorized in paragraph (f)
hereof. This power of attorney shall be liberally, not restrictively, construed so as to give the
greatest latitude to the Administrative Agent’s and the Collateral Agent’s power, as attorney,
relative to the Collateral matters described in this Section 9.03. The powers and authorities
herein conferred on the Administrative Agent and Collateral Agent may be exercised by the
Administrative Agent or Collateral Agent through any Person who, at the time of the execution of a
particular instrument, is an officer of the Administrative Agent or Collateral Agent (or any Person
acting on behalf of the Administrative Agent or Collateral Agent pursuant to a valid power of
attorney). The power of attorney conferred by this Section 9.03(g) to the Administrative Agent and
Collateral Agent is granted for valuable consideration and is coupled with an interest and is
irrevocable so long as the Obligations, or any part thereof, shall remain unpaid or the Lenders
have any Revolving Commitment hereunder.

     9.04. Liability of Agents. No Agent-Related Person shall (a) be liable for any action taken or
omitted to be taken by any of them under or in connection with this Agreement or any other Loan
Document or the transactions contemplated hereby (except for its own gross negligence or willful
misconduct in connection with its duties expressly set forth herein), or (b) be responsible in any
manner to any Lender or Participant for any recital, statement, representation or warranty made by
any Loan Party or any officer thereof, contained herein or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in, or received by
Administrative Agent or Collateral Agent under or in connection with, this Agreement or any other
Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Document, or for the creation, perfection or priority of any Liens
purported to be created by any of the Loan Documents, or the validity, genuineness, enforceability,
existence, value or sufficiency of any collateral security, or to make any inquiry respecting the
performance by the Borrowers of their obligations hereunder or under any other Loan Document, or
for any failure of any Loan Party or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any obligation to any
Lender or Participant to ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect
the properties, books or records of any Loan Party or any Affiliate thereof.

     9.05. Reliance by Administrative Agent. (a) The Administrative Agent shall be entitled to rely,
and shall be fully protected in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate, affidavit, letter, facsimile, electronic mail message
or telephone message, statement or other document or conversation believed by it to be genuine and
correct

Borrowing Base
Credit Agreement

84

 

and to have been signed, sent or made by the proper Person or Persons, and upon advice and
statements of legal counsel (including counsel to any Loan Party), independent accountants and
other experts selected by the Administrative Agent. The Administrative Agent shall be fully
justified in failing or refusing to take any action under any Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders as it deems appropriate and, if it so
requests, it shall first be indemnified to its satisfaction by the Lenders against any and all
liability and expense which may be incurred by it by reason of taking or continuing to take any
such action. The Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or any other Loan Document in accordance with a
request or consent of the Required Lenders or all the Lenders, if required hereunder, and such
request and any action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and Participants. Where this Agreement expressly permits or prohibits an action unless the
Required Lenders otherwise determine, the Administrative Agent shall, and in all other instances,
the Administrative Agent may, but shall not be required to, initiate any solicitation for the
consent or a vote of the Lenders.

     (b) For purposes of determining compliance with the conditions specified in Section 4.01, each
Lender that has funded its Pro Rata Share of the Borrowing on the Closing Date shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document or other matter
either sent by the Administrative Agent to such Lender (or otherwise made available for such Lender
on Intralinks or any similar website) for consent, approval, acceptance or satisfaction, or
required hereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

     9.06. Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice
of the occurrence of any Default or Event of Default, except with respect to defaults in the
payment of principal, interest and fees required to be paid to the Administrative Agent for the
account of the Lenders, unless the Administrative Agent shall have received written notice from a
Lender or the Borrowers referring to this Agreement, describing such Default or Event of Default
and stating that such notice is a “notice of default.” The Administrative Agent will notify the
Lenders of its receipt of any such notice. The Administrative Agent shall take such action with
respect to such Default or Event of Default as may be directed by the Required Lenders in
accordance with Article VIII; provided, however, that unless and until the Administrative Agent has
received any such direction, the Administrative Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default or Event of Default as it
shall deem advisable or in the best interest of the Lenders.

     9.07. Credit Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges
that no Agent-Related Person has made any representation or warranty to it, and that no act by the
Administrative Agent hereinafter taken, including any consent to and acceptance of any assignment
or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to constitute
any representation or warranty by any Agent-Related Person to any Lender as to any matter,
including whether Agent-Related Persons have disclosed material information in their possession.
Each Lender represents to the Administrative Agent that it has, independently and without reliance
upon any Agent-Related Person and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business, prospects, operations,
property, financial and
other condition and creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made
its own decision to enter into this Agreement and to extend credit to the Borrowers hereunder.
Each Lender also represents that it will, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such investigations as it deems
necessary to inform itself as to the business, prospects, operations, property, financial and other
condition and creditworthiness of the

Borrowing Base
Credit Agreement

85

 

Borrowers and the other Loan Parties. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by the Administrative
Agent herein, the Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, prospects, operations,
property, financial and other condition or creditworthiness of any of the Loan Parties or any of
their respective Affiliates which may come into the possession of any Agent Related Person.

     9.08. Indemnification of Agents. Whether or not the transactions contemplated hereby are
consummated, the Lenders shall indemnify upon demand each Agent-Related Person (to the extent not
reimbursed by or on behalf of any Loan Party and without limiting the obligation of any Loan Party
to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all
Indemnified Liabilities incurred by it; provided, however, that no Lender shall be liable for the
payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent
determined in a final, nonappealable judgment by a court of competent jurisdiction to have been
caused primarily by such Agent-Related Person’s own gross negligence or willful misconduct;
provided, however, it being agreed by all Lenders that no action taken in accordance with the
directions of the Required Lenders shall be deemed to constitute gross negligence or willful
misconduct for purposes of this Section. Without limitation of the foregoing, each Lender shall
reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket
expenses (including Attorney Costs, costs and expenses in connection with the use of Intralinks,
Inc. or other similar information transmission systems in connection with this Agreement and FA
Costs) incurred by the Administrative Agent in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether through negotiations,
legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to
the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the
Borrowers. The undertaking in this Section shall survive termination of the Revolving Commitments,
the payment of all Obligations hereunder and the resignation or replacement of the Administrative
Agent.

     9.09. Administrative Agent in its Individual Capacity. RBC and its Affiliates may make loans to,
accept deposits from, acquire equity interests in and generally engage in any kind of banking,
trust, financial advisory, underwriting or other business with each of the Loan Parties and their
respective Affiliates as though RBC were not the Administrative Agent, Collateral Agent or the L/C
Issuer hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that,
pursuant to such activities, RBC or its Affiliates may receive information regarding any Loan Party
or its Affiliates (including information that may be subject to confidentiality obligations in
favor of such Loan Party or such Affiliate) and acknowledge that the Administrative Agent shall be
under no obligation to provide such information to them. With respect to its Revolving Loans, RBC
shall have the same rights and powers under this Agreement as any other Lender and may exercise
such rights and powers as though it were not the Administrative Agent, Collateral Agent or the L/C
Issuer, and the terms “Lender” and “Lenders” include RBC in its individual capacity.

     9.10. Successor Administrative Agent and Collateral Agent.

     (a) The Administrative Agent may resign as Administrative Agent and Collateral Agent upon 30
days’ notice to the Lenders with a copy of such notice to the Borrowers. If the Administrative
Agent resigns under this Agreement, the Required Lenders shall appoint from among the Lenders a
successor administrative agent and collateral agent for the Lenders which successor administrative
agent shall be consented to by the Borrowers at all times other than during the existence of an
Event of Default (which consent of the Borrowers shall not be unreasonably withheld, conditioned or
delayed). If no successor administrative agent is appointed prior to the effective date of the
resignation of the

Borrowing Base
Credit Agreement

86

 

Administrative Agent, the Administrative Agent may appoint, after consulting
with the Lenders and the Borrowers, a successor administrative agent from among the Lenders who
shall also succeed to the role of successor collateral agent. Upon the acceptance of its
appointment as successor administrative agent hereunder, such successor administrative agent shall
succeed to all the rights, powers and duties of the retiring Administrative Agent and the term
"Administrative Agent” shall mean such successor administrative agent and the retiring
Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated.
After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the
provisions of this Article IX and Sections 10.04 and 10.13 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.
If no successor administrative agent has accepted appointment as Administrative Agent by the date
which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring
Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders
shall perform all of the duties of the Administrative Agent and Collateral Agent hereunder until
such time, if any, as the Required Lenders appoint a successor agent as provided for above.

     (b) The Collateral Agent may resign as Collateral Agent upon 30 days’ notice to the
Administrative Agent with a copy of such notice to the Borrowers. If the Collateral Agent resigns
under this Agreement, the Administrative Agent shall designate a successor collateral agent. Upon
the acceptance of its appointment as successor collateral agent hereunder, such successor
collateral agent shall succeed to all the rights, powers and duties of the retiring Collateral

advances of the Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.08, 10.04 and 10.05.

authorized by the Lenders to) execute such documents as may be necessary to evidence the release of
Liens granted to the Administrative Agent and/or Collateral Agent for the benefit of the Secured
Parties pursuant hereto in such Collateral. Neither the Administrative Agent nor the Collateral
Agent shall be required to execute any release instruments on terms which, in the Administrative
Agent’s (or Collateral Agent’s) opinion, would expose the Administrative Agent or Collateral Agent
to liability or create any obligation or entail any consequence other than the release of Liens
without recourse or warranty. No such release shall impair the Administrative Agent’s and/or
Collateral Agent’s Lien on the proceeds of sale of such Collateral.

     (d) If all outstanding Revolving Loans and other Obligations (other than contingent indemnity
obligations) have been indefeasibly paid in full (or, with respect to L/C Obligations, Cash

subject to Section 10.01(e) all Lender Hedging Agreement have terminated, the Administrative Agent
agrees to, and the Lenders hereby instruct the Administrative Agent and Collateral Agent to, at the
Borrowers’ expense, execute and authorize such releases of the Collateral Documents as the
Borrowers shall reasonably request and this Agreement shall be deemed terminated except that such
termination shall not relieve the Borrowers of any obligation to make any payments to the
Administrative Agent or any Lender required by any Loan Document to the extent accruing, or
relating to an event occurring, prior to such termination.

     (e) Notwithstanding any provision herein to the contrary, if the Revolving Commitments have
been terminated, and the only outstanding Obligations (other than contingent indemnity obligations
and L/C Obligations that are Cash Collateralized) are amounts owed pursuant to one or more Lender
Hedging Agreements, the Administrative Agent and/or Collateral Agent will, and is hereby authorized
to, (A) release the Liens created under the Loan Documents and (B) release all Guaranties of the
Guarantors; provided, that contemporaneously with such release, (i) the Borrowers (and, if
applicable, any Borrower Affiliate that is a party to such Lender Hedging Agreements) (A) execute a
margin agreement in form and substance acceptable to such Lender(s) (or its Affiliates) that are
parties to such Lender Hedging Agreements (the “Lender Counterparties”) and (B), if required,
provide collateral in the form of cash or a letter of credit having an aggregate value acceptable
to such Lender Counterparties, and (ii) if such Lender Hedging Agreement is executed by a
Subsidiary of the Borrowers and the Borrowers are not parties thereto, the Borrowers execute a

voicemail message shall in no event be effective as a notice, communication or confirmation

     (b) Effectiveness of Facsimile Documents and Signatures. Loan Documents may be
transmitted and/or signed by facsimile or other electronic means. The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force and effect as
manually-signed originals and shall be binding on all Loan Parties, the Administrative Agent and
the Lenders. The Administrative Agent may also require that any such documents and signatures be
confirmed by a manually-signed original thereof; provided, however, that the failure to request or
deliver the same shall not limit the effectiveness of any facsimile document or signature.

     (c) Limited Use of Electronic Mail. Electronic mail and internet and intranet
websites may be used only to distribute routine communications, such as financial statements and
other information, and to distribute Loan Documents for execution by the parties thereto, and shall
not be recognized hereunder for any other purpose.

     (d) Reliance by Administrative Agent and Lenders. The Administrative Agent and the
Lenders shall be entitled to rely and act upon any notices (including telephonic Borrowing Notices)
purportedly given by or on behalf of the Borrowers even if (i) such notices were not made in a
manner specified herein, were incomplete or were not preceded or followed by any other form of
notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any
confirmation thereof. The Borrowers shall indemnify each Agent-Related Person and each Lender from
all losses, costs, expenses and liabilities resulting from the reliance by such Person on each
notice purportedly given by or on behalf of the Borrowers. All telephonic notices to and other
communications with the Administrative Agent may be recorded by the Administrative Agent, and each
of the parties hereto hereby consents to such recording.

     10.03. No Waiver; Cumulative Remedies. No failure by any Lender or the Administrative Agent to
exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege
hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right,
remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise
of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein
or therein provided are cumulative and not exclusive of any rights, remedies, powers and privileges
provided by law.

thereof and any and all other documents or instruments of further assurance required to be filed or
recorded or refiled or rerecorded by the terms hereof or of any mortgage, any pledge agreement or
any security agreement, and any amendment, waiver, consent or other modification of the provisions

     10.05. Indemnification. Whether or not the transactions contemplated hereby are consummated, each of the Borrowers and
each other Guarantor (by execution of a Guaranty), jointly and severally, agrees to indemnify, save
and hold harmless each Agent-Related Person, the Administrative Agent, the Collateral Agent, each
Lender, the L/C Issuer and their respective Affiliates, directors, officers, employees, counsel,
agents and attorneys-in-fact (collectively the “Indemnitees”) from and against: (a) any and all
claims, demands, actions or causes of action that are asserted against any Indemnitee by any Person

the Loan Documents, the Revolving Commitments, the use or contemplated use of the proceeds of any
Revolving Loans, or the relationship of any Loan Party, the Administrative Agent, the Collateral

settlement entered into by the Administrative Agent or such Lender in its discretion) to be repaid
to a trustee, receiver or any other party, in connection with any proceeding under any Debtor
Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such setoff had not occurred, and (b) each Lender severally
agrees to pay to the Administrative Agent upon demand its applicable share of any amount so
recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such
demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from
time to time in effect.

Commitment and the Revolving Loans (including for purposes of this subsection (b), participations
in L/C Obligations) at the time owing to it); provided that:

except in the case of an assignment of the entire remaining amount of the assigning Lender’s
Revolving Commitment and the Revolving Loans at the time owing to it or in the case of an
assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender,
the aggregate amount of the Revolving Commitment (which for this purpose includes Revolving Loans
outstanding thereunder) or, if the applicable Revolving Commitment is not then in effect, the
outstanding principal balance of the Revolving Loan of the assigning Lender subject to each such
assignment (determined as of the date the Assignment and Assumption with respect to such assignment
is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and
Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the
Administrative Agent and, so long as no Event of Default has occurred and is continuing, the
Borrowers otherwise consent (neither the Administrative Agent’s nor Borrowers’ consent to be
unreasonably withheld, conditioned or delayed);

     (i) each partial assignment shall be made as an assignment of a proportionate part of
all the assigning Lender’s rights and obligations under this Agreement with respect to the
Revolving Loan or the Revolving Commitment assigned;

     (ii) any assignment of a Revolving Commitment must be approved by the Administrative
Agent and L/C Issuer unless the Person that is the proposed assignee is itself a Lender

Agent an Assignment and Assumption, together with a processing and recordation fee of
$3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the

Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled
to the benefits of Sections 3.07, 10.04 and 10.05 with respect to facts and circumstances
occurring prior to the effective date of such assignment. Any assignment or transfer by a

participation in such rights and obligations in accordance with paragraph (d) of this
Section.

     (c) The Administrative Agent, acting solely for this purpose as an agent of the Borrowers,
shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the Revolving

Register shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent and
the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms
hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register shall be available for inspection by the Borrowers and any Lender, at any
reasonable time and from time to time upon reasonable prior notice.

     (d) Any Lender may at any time, without the consent of, or notice to, the Borrowers or the
Administrative Agent, sell participations to any Person (other than a natural person or the
Borrowers or any of the Borrowers’ Affiliates or Subsidiaries) (each, a “Participant”) in all or a
portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion

hereto for the performance of such obligations and (iii) the Borrowers, the Administrative Agent
and the other Lenders shall continue to deal solely and directly with such Lender in connection
with such Lender’s rights and obligations under this Agreement. Any agreement or instrument
pursuant to which a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver that would (i) postpone any date upon
which any payment of money is scheduled to be paid to such Participant, (ii) reduce the principal,
interest, fees or other amounts payable to such Participant, or (iii) release Parent from its
Guaranty. Subject to subsection (e) of this Section, the Borrowers agree that each Participant
shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were
a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section;
provided said Participant agrees to be subject to Sections 3.08 and 10.15 as though it were a
Lender. To the extent permitted by Law, each Participant also shall be entitled to the benefits of
Section 10.09 as though it were a Lender; provided such Participant agrees to be subject to Section
2.12 as though it were a Lender.

     (e) A Participant shall not be entitled to receive any greater payment under Section 3.01 or
3.04 than the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to such Participant is
made with the Borrowers’ prior written consent. A Participant that would be a Foreign Lender if it
were a Lender shall not be entitled to the benefits of Section 3.01 unless the Borrowers are
notified of the participation sold to such Participant and such Participant agrees, for the benefit
of the Borrowers, to comply with Section 3.01 as though it were a Lender.

     (f) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement (including under its Revolving Notes, if any) to secure obligations
of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank;
provided that no such pledge or assignment shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     (g) If the consent of the Borrowers to an assignment or to an Eligible Assignee is required
hereunder (including a consent to an assignment which does not meet the minimum assignment
threshold specified in clause (i) of the proviso to the first sentence of Section 10.07(b)), the
Borrowers shall be

95

 

deemed to have given their consent five Business Days after the date notice
thereof has been delivered by the assigning Lender (through the Administrative Agent) unless such
consent is expressly refused by the Borrowers prior to such fifth Business Day.

     (h) Notwithstanding anything to the contrary contained herein, if at any time RBC assigns all
of its Revolving Commitment and Revolving Loans pursuant to subsection (b) above, RBC may, upon 30
days’ notice to the Borrowers and the Lenders, resign as L/C Issuer. In the event of any such
resignation as L/C Issuer, the Borrowers shall be entitled to appoint from among the Lenders a
successor L/C Issuer hereunder; provided, however, that any such successor L/C Issuer have accepted
such appointment; provided further, however, that no failure by the Borrowers to appoint any such
successor shall affect the resignation of RBC as L/C Issuer. RBC shall retain all the rights and
obligations of the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of the
effective date of its resignation as L/C Issuer and all L/C Obligations with respect thereto
(including the right to require the Lenders to make Base Rate Loans or fund participations in
Unreimbursed Amounts pursuant to Section 2.14(c)).

     10.08. Confidentiality. Each Lender agrees that it will not disclose without the prior consent of
the Borrowers (other than to directors, officers, employees, auditors, accountants, counsel or
other professional advisors of the Administrative Agent or any Lender) any information with respect
to the Borrowers or any of their respective Subsidiaries, which is furnished pursuant to this
Agreement; provided that any Lender may disclose any such information (a) as has become generally
available to the public, (b) as may be required
or appropriate in any report, statement or testimony submitted to or required by any municipal,
state or federal regulatory body having or claiming to have jurisdiction over such Lender or
submitted to or required by the Board or the Federal Deposit Insurance Corporation or similar
organizations (whether in the United States or elsewhere) or their successors, (c) as may be
required or appropriate in response to any summons or subpoena in connection with any litigation,
(d) in order to comply with any law, order, regulation or ruling applicable to such Lender, (e) to
any Eligible Assignee of or Participant in, or any prospective Eligible Assignee of or Participant
in, any of its rights or obligations under this Agreement; provided that such Eligible Assignee or
Participant or prospective Eligible Assignee or Participant executes an agreement containing
provisions substantially similar to those contained in this Section 10.08, (f) in connection with
the exercise of any remedy by such Lender if an Event of Default pertaining to the Loan Documents
has occurred and is continuing, (g) in connection with any litigation involving such Lender
pertaining to the Loan Documents, (h) to any Lender or the Administrative Agent, or (i) to any
Affiliate of any Lender (it being understood that the Persons to whom such disclosure is made will
be informed of the confidential nature of such information and obligated to keep such information
confidential).

     10.09. Set-off. In addition to any rights and remedies of the Lenders provided by Law, upon the
occurrence and during the continuance of any Event of Default, each Lender is authorized at any
time and from time to time, without prior notice to the Borrowers or any other Guarantor, any such
notice being waived by the Borrowers (each on its own behalf and on behalf of each Guarantor) 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 by, and other indebtedness at any time owing
by, such Lender to or for the credit or the account of the respective Borrowers or Guarantor, as
applicable, against any and all Obligations owing to the Administrative Agent and the Lenders, now
or hereafter existing, irrespective of whether or not the Administrative Agent or such Lender shall
have made demand under this Agreement or any other Loan Document and although such Obligations may
be contingent or unmatured. Each Lender agrees promptly to notify the Borrowers and the
Administrative Agent after any such set-off and application made by such Lender; provided, however,
that the failure to give such notice shall not affect the validity of such set-off and application.

Credit Agreement

     10.10. Interest Rate Limitation. Regardless of any provision contained in any Loan Document,
neither the Administrative Agent nor any Lender shall ever be entitled to contract for, charge,
take, reserve, receive, or apply, as interest on all or any part of the Obligations, any amount in
excess of the Maximum Rate, and, if any Lender ever does so, then such excess shall be deemed a
partial prepayment of principal and treated hereunder as such and any remaining excess shall be
refunded to the Borrowers. In determining if the interest paid or payable exceeds the Maximum
Rate, the Borrowers and the Lenders shall, to the maximum extent permitted under applicable Law,
(a) treat all Borrowings as but a single extension of credit (and the Lenders and the Borrowers
agree that such is the case and that provision herein for multiple Borrowings is for convenience
only), (b) characterize any nonprincipal payment as an expense, fee, or premium rather than as
interest, (c) exclude voluntary prepayments and the effects thereof, and (d) amortize, prorate,
allocate, and spread the total amount of interest throughout the entire contemplated term of the
Obligations. However, if the Obligations are 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 Amount, the Lenders shall refund such excess, and, in such event, the
Lenders shall not, to the extent permitted by Law, be subject to any penalties provided by any Laws
for contracting for, charging, taking, reserving or receiving interest in excess of the Maximum
Amount.

     10.11. Counterparts. This Agreement may be executed in one or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and the same agreement.
Delivery of an executed counterpart of a signature page of this Agreement by telecopy, facsimile,
photocopy or by sending a scanned copy by electronic mail shall be effective as delivery of a
manually executed counterpart of this Agreement. Any signature page of a counterpart may be
detached therefrom without impairing the legal effect of the signatures thereon and attached to
another counterpart identical in form thereto but having attached to it one or more additional
signature pages signed by other parties.

     10.12. Integration. This Agreement, together with the other Loan Documents, comprises the complete
and integrated agreement of the parties on the subject matter hereof and thereof and supersedes all
prior agreements, written or oral, on such subject matter. In the event of any conflict between
the provisions of this Agreement and those of any other Loan Document, the provisions of this
Agreement shall control; provided that the inclusion of supplemental rights or remedies in favor of
the Administrative Agent or the Lenders in any other Loan Document shall not be deemed a conflict
with this Agreement. Each Loan Document was drafted with the joint participation of the respective
parties thereto and shall be construed neither against nor in favor of any party, but rather in
accordance with the fair meaning thereof.

     10.13. Survival of Representations and Warranties. All representations and warranties made
hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or
in connection herewith or therewith shall survive the execution and delivery hereof and thereof.
Such representations and warranties have been or will be relied upon by the Administrative Agent
and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or
on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice
or knowledge of any Default or Event of Default at the time of any Borrowing, and shall continue in
full force and effect as long as any Revolving Loan or any other Obligation shall remain unpaid or
unsatisfied.

     10.14. Severability. Any provision of this Agreement and the other Loan Documents to which any
Borrower is a party that is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without
invalidating the

Borrowing Base
Credit Agreement

97

 

remaining provisions thereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

     10.15. Replacement of Lenders. If Required Lenders and the Administrative Agent have approved an
identical increase of the Borrowing Base, the Borrowers shall have the right to replace any Lenders
that have failed to approve such Borrowing Base increase pursuant to the provisions of the
following sentence. If (i) any Lender fails or refuses to consent to any requested amendment or
waiver pursuant to Section 10.01, (ii) any Lender requests compensation under Section 3.04, or if
the Borrowers are required to pay any additional amount to any Lender or any Governmental Authority
for the account of any Lender pursuant to Section 3.01, (iii) any Lender is in breach of any of its
obligations under this Agreement or is otherwise a Defaulting Lender, or (iv) any other
circumstance exists hereunder that gives the Borrowers the right to replace a
Lender as a party hereto, then the Borrowers may, at their sole expense and effort, upon notice to
such Lender and the Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in, and consents required
by, Section 10.07), all of its interests, rights and obligations under this Agreement and the
related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee
may be another Lender, if a Lender accepts such assignment); provided that:

     (a) the Borrowers shall have paid to the Administrative Agent the assignment fee specified in
Section 10.07(b)(iii);

     (b) such Lender shall have received payment of an amount equal to the outstanding principal of
its Revolving Loans, L/C Advances, L/C Borrowings, accrued interest thereon, accrued fees and all
other amounts payable to it hereunder and under the other Loan Documents (including any amounts
under Section 3.05) from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Borrowers (in the case of all other amounts) such payment being at par,
with no premium or discount;

     (c) in the case of any such assignment resulting from a claim for compensation under Section
3.04 or payments required to be made pursuant to Section 3.01, such assignment will result in a
reduction in such compensation or payments thereafter; and

     (d) such assignment does not conflict with applicable Laws.

     A Lender shall not be required to make any such assignment or delegation if, prior thereto, as
a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to
require such assignment and delegation cease to apply.

     10.16. Defaulting Lender.

     (a) Notwithstanding anything to the contrary contained in this Agreement, if any Lender
becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender,
to the extent permitted by applicable law:

     (i) That Defaulting Lender’s right to approve or disapprove any amendment, waiver or
consent with respect to this Agreement shall be restricted.

     (ii) Any payment of principal, interest, fees or other amounts received by the
Administrative Agent for the account of that Defaulting Lender (whether voluntary or
mandatory, at maturity, pursuant to Section 2.04 (Prepayments) or otherwise, and including
any amounts made available to the Administrative Agent by the Defaulting Lender pursuant
to a

Borrowing Base
Credit Agreement

98

 

right of set-off, shall be applied at such time or times as may be determined by the
Administrative Agent as follows:

first, to the payment of any amounts owing by that Defaulting Lender to the Administrative
Agent hereunder;

second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to
an L/C Issuer hereunder;

third, if so determined by the Administrative Agent or requested by the L/C Issuer, to be
held as cash collateral for future funding obligations of that Defaulting Lender of any
participation in any Letter of Credit;

fourth, as the Borrowers may request (so long as no Default or Event of Default exists), to
the funding of any Loan in respect of which that Defaulting Lender has failed to fund its
portion thereof as required by this Agreement, as determined by the Administrative Agent;

fifth, if so determined by the Administrative Agent and the Borrowers, to be held in a
deposit account and released in order to satisfy obligations of that Defaulting Lender to
fund Loans under this Agreement;

sixth, to the payment of any amounts owing to the Lenders, the L/C Issuer as a result of any
judgment of a court of competent jurisdiction obtained by any Lender, the L/C Issuer against
that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations
under this Agreement;

seventh, so long as no Default or Event of Default exists, to the payment of any amounts
owing to the Borrowers as a result of any judgment of a court of competent jurisdiction
obtained by the Borrowers against that Defaulting Lender as a result of that Defaulting
Lender’s breach of its obligations under this Agreement; and

eighth, to that Defaulting Lender or as otherwise directed by a court of competent
jurisdiction; provided that if (x) such payment is a payment of the principal amount of any
Loans or reimbursement obligations in respect of which that Defaulting Lender has not fully
funded its appropriate share and (y) such Loans or reimbursement obligations were made at a
time when the conditions set forth in Section 4.02 were satisfied or waived, such payment
shall be applied solely to pay the Loans of, and reimbursement obligations owed to, all
non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any
Loans of, or reimbursement obligations owed to, that Defaulting Lender.

Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied
(or held) to pay amounts owed by a Defaulting Lender or to post cash collateral pursuant to this
Section 10.16 shall be deemed paid to and redirected by that Defaulting Lender, and each Lender
irrevocably consents hereto.

     (iii) That Defaulting Lender (x) shall not be entitled to receive any commitment fee
for any period during which that Lender is a Defaulting Lender (and the Borrowers shall
not be required to pay any such fee that otherwise would have been required to have been
paid to that Defaulting Lender) and (y) shall be limited in its right to receive fees in
respect of Letter of Credit (if any).

     (iv) During any period in which there is a Defaulting Lender, for purposes of
computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance
or fund participations in Letters of Credit the ratable portion of each non-Defaulting
Lender shall be computed without giving effect to the Revolving Commitments of that
Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only
if, at the date the Lender becomes a Defaulting Lender, no Default or Event of Default
exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire,
refinance or fund participations in Letters of Credit shall not exceed the positive
difference, if any, of (1) the Revolving Commitments of that non-Defaulting Lender minus
(2) the aggregate Outstandings of that Lender.

     (b) If the Borrowers, the Administrative Agent, and the L/C Issuer agree in writing in their
sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the
Administrative Agent will so notify the parties hereto, whereupon as of the effective date
specified in such notice and subject to any conditions set forth therein (which may include
arrangements with respect to any cash collateral), that Lender will, to the extent applicable,
purchase that portion of outstanding Loans of the other Lenders or take such other actions as the
Administrative Agent may determine to be necessary to cause the Loans and participations in Letters
of Credit to be held on a pro rata basis by the Lenders in accordance with their ratable portions
(without giving effect to clause (a)(iv) above), whereupon that Lender will cease to be a
Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees
accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting
Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected
parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release
of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

     (c) If any Lender is a Defaulting Lender, then the Borrowers may, at their sole expense and
effort, upon notice to such Lender and the Administrative Agent, require such Lender to be replaced
in accordance with Section 10.15.

     10.17. Governing Law.

and discharge, from any lien securing the Indebtedness under this Agreement, the KPC Pipeline and
the KPC Pipeline LLC equity contemporaneously with the release of the first lien held by RBC as
collateral agent (or its successor) for the benefit of the KPC Lenders.

     10.22. Amendment and Restatement. Pursuant to (i) the Assignment of First Lien Notes, on the

Credit Agreement

102

 

of any obligation of any Borrower
thereunder. Only to the extent of an increase in the Aggregate Revolving Commitment over that
amount shall there be deemed to be a new advance by the Lenders to the Borrowers under this
Agreement. The Indebtedness owing under the Prior Credit Agreements is renewed, rearranged,
extended and carried forward by this Agreement (to the extent aforesaid) and all of the liens and
security interests securing the “Obligations” as defined in the Prior Credit Agreements are carried
forward and secure, without interruption or loss or priority, the Obligations under this Agreement.

     10.25. Joint and Several Liability. (a) Each of the Borrowers acknowledges and agrees that it is
the intent of the parties that each such Borrower be primarily liable for the Obligations as a
joint and several obligor. It is the intention of the parties that with respect to liability of any
Borrower hereunder arising solely by reason of its being jointly and severally liable for Credit
Extensions, the obligations of such Borrower shall be absolute, unconditional and irrevocable
irrespective of:

     (i) any lack of validity, legality or enforceability of this Agreement, any Revolving
Note, or any other Loan Document as to any Borrower, as the case may be;

     (ii) the failure of the Administrative Agent, Collateral Agent or any Lender or any
holder of any Revolving Note;

     (a) to enforce any right or remedy against any Borrower, as the case may be, or
any other Person (including any Guarantor) under the provisions of this Agreement,
such Revolving Note, any other Loan Document or otherwise; or

     (b) to exercise any right or remedy against any Guarantor of, or Collateral
securing, the Obligations;

     (iii) any change in the time, manner or place of payment of, or in any other term of,
all or any of the Obligations, or any other extension, compromise or renewal of any
Obligations;

     (iv) any reduction, limitation, impairment or termination of any Obligations with
respect to any Borrower, as the case may be, for any reason, including any claim of
waiver, release, surrender, alteration or compromise, and shall not be subject to (and
each of the Borrowers hereby waives any right to or claim of) any defense (other than the
defense of payment in full of the Obligations) or setoff, counterclaim, recoupment or
termination whatsoever by reason of the invalidity, illegality, nongenuineness,
irregularity, compromise, unenforceability of, or any other event or occurrence affecting,
any Obligations with respect to any Borrower, as the case may be;

     (v) any addition, exchange, release, surrender or nonperfection of any Collateral, or
any amendment to or waiver or release or addition of, or consent to departure from, any
Guaranty, held by any Lender or any holder of the Revolving Notes or any security interest
or Lien securing any of the Obligations; or

     (vi) any other circumstance which might otherwise constitute a defense (other than
the defense of payment in full of the Obligations) available to, or a legal or equitable
discharge of, any Borrower, as the case may be, or any Guarantor.

     (b) Each of the Borrowers agrees that its joint and several liability hereunder shall continue
to be effective or be reinstated, as the case may be, if at any time any payment (in whole or in
part) of any of the Obligations is rescinded or must be restored by any Lender or any holder of any
Revolving Note,

Borrowing Base
Credit Agreement

103

 

upon the insolvency, bankruptcy or reorganization of any Borrower, as the case may
be, as though such payment had not been made;

     (c) Each of the Borrowers hereby expressly waives: (i) notice of the Lenders’ acceptance of
this Agreement; (ii) notice of the existence or creation or non-payment of all or any of the
Obligations other than notices expressly provided for in this Agreement; (iii) presentment, demand,
notice of dishonor, protest, and all other notices whatsoever other than notices expressly provided
for in this Agreement; (iv) any claim or defense based on an election of remedies; and (v) all
diligence in collection or protection of or realization upon the Obligations or any part thereof,
any obligation hereunder, or any security for or guaranty of any of the foregoing.

     (d) No delay on any of the Administrative Agent’s, Collateral Agent’s or any Secured Party’s
part in the exercise of any right or remedy shall operate as a waiver thereof, and no single or
partial exercise by any of the foregoing of any right or remedy shall preclude other or further
exercise thereof or the exercise of any other right or remedy. No action of any of the
Administrative Agent, Collateral Agent or Secured Parties permitted hereunder shall in any way
affect or impair any such party’s rights or any Obligations under this Agreement.

     (e) Each of the Borrowers hereby represents and warrants to each of the Administrative Agent
and Lenders that it now has and will continue to have independent means of obtaining information
concerning the other Borrower’s affairs, financial condition and business. Neither the
Administrative Agent nor any Lender shall have any duty or responsibility to provide any Borrower
with any credit or other information concerning such other Borrower’s affairs, financial condition
or business which may come into the Administrative Agent’s or Lender’s possession.

     (f) Each of the Borrowers represents and warrants (i) that the business operations of the
Borrowers are interrelated and that the business operations of the Borrowers complement one
another, and such entities have a common business purpose, and (ii) that, to permit their
uninterrupted and continuous operations, such entities now require and will from time to time
hereafter require funds and credit accommodations for general business purposes and (iii) that the
proceeds of Credit Extensions hereunder will directly or indirectly benefit the Borrowers
hereunder, severally and jointly, regardless of which Borrower receives part or all of the proceeds
of such Credit Extension.

     (g) Notwithstanding anything to the contrary contained herein, it is the intention of the
Borrowers, the Administrative Agent and the Lenders that the amount of the respective Borrower’s
obligations hereunder shall be in, but not in excess of, the maximum amount thereof not subject to
avoidance or recovery by operation of any applicable Debtor Relief Law. To that end, but only in
the event and to the extent that the Borrowers’ respective obligations hereunder or any payment
made pursuant thereto would, but for the operation of the foregoing proviso, be subject to
avoidance or recovery under any applicable Debtor Relief Law, the amount of the Borrowers’
respective obligations hereunder shall be limited to the largest amount which, after giving effect
thereto, would not, under applicable Debtor Relief Laws, render the Borrower’s respective
obligations hereunder unenforceable or avoidable or subject to recovery under applicable Debtor
Relief Laws. To the extent any payment actually made hereunder exceeds the limitation contained in
this Section 10.25(g), then the amount of such excess shall, from and after the time of payment by
the Borrowers (or any of them), be reimbursed by the Lenders upon demand by such Borrowers. The
foregoing proviso is intended solely to preserve the rights of the Administrative Agent and the
Lenders hereunder against the Borrowers to the maximum extent permitted by applicable Debtor Relief
Laws and neither any Borrower nor any Guarantor nor any other Person shall
have any right or claim under this Section 10.25(g) that would not otherwise be available
under applicable Debtor Relief Laws.

or such lesser principal amount of Revolving Loans made by Lender under the Facility (both as
defined in such Credit Agreement) due and payable by the Borrowers to the Lender on the Maturity

shall become, or may be declared to be, immediately due and payable all as provided in the Credit
Agreement. Revolving Loans made by the Lender shall be evidenced by one or more loan accounts or
records maintained by the Lender in the ordinary course of business. The Lender may also attach
schedules to this Revolving Note and endorse thereon the date, amount and maturity of its Revolving
Loans and payments with respect thereto.

     This Revolving Note is a Loan Document and is subject to Section 10.10 of the Credit
Agreement, which is incorporated herein by reference the same as if set forth herein verbatim.

     Each Borrower, for itself, its successors and assigns, hereby waives diligence, presentment,
