The Credits

     Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make revolving loans
to the Borrower during the Availability Period in an aggregate principal amount that will not
result in (a) such Lender’s Credit Exposure exceeding such Lender’s Commitment or (b) the total
Credit Exposures exceeding the total Commitments. Within the foregoing limits and subject to the
terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans.

     Section 2.02 Loans and Borrowings.

          (a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing
consisting of Loans made by the Lenders ratably in accordance with their respective Commitments.
The failure of any Lender to make any Loan required to be made by it shall not relieve any other
Lender of its obligations hereunder; provided that the Commitments are several and no
Lender shall be responsible for any other Lender’s failure to make Loans as required.

29

 

          (b) Types of Loans. Subject to Section 3.03, each Borrowing shall be
comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance
herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of
such option shall not affect the obligation of the Borrower to repay such Loan in accordance with
the terms of this Agreement.

          (c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each
Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that
is an integral multiple of $1,000,000 and not less than $1,000,000. At the time that each ABR
Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of
$1,000,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an
aggregate amount that is equal to the entire unused balance of the total Commitments or that is
required to finance the reimbursement of an LC Disbursement as contemplated by Section
2.09(e). Borrowings of more than one Type may be outstanding at the same time,
provided that there shall not at any time be more than a total of ten (10) Eurodollar
Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall
not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest
Period requested with respect thereto would end after the Maturity Date.

          (d) Notes. The Loans made by each Lender, if requested by such Lender, shall be
evidenced by a single promissory note of the Borrower in substantially the form of Exhibit
A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of
the date of this Agreement, (ii) any Lender that becomes a party hereto pursuant to an Assignment
and Assumption, as of the effective date of the Assignment and Assumption, or (iii) any Lender that
becomes a party hereto in connection with an increase in the total Commitments pursuant to
Section 2.07(d), as of the effective date of such increase, in each case, payable to the
order of such Lender in a principal amount equal to its Commitment as in effect on such date, and
otherwise duly completed. In the event that any Lender’s Commitment increases or decreases for any
reason (whether pursuant to Section 2.07, Section 12.04(b) or otherwise), if
requested by such Lender, the Borrower shall deliver or cause to be delivered on the effective date
of such increase or decrease, a new Note payable to the order of such Lender in a principal amount
equal to its Commitment after giving effect to such increase or decrease, and otherwise duly
completed. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan
made by each Lender, and all payments made on account of the principal thereof, shall be recorded
by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such
Lender on a schedule attached to such Note or any continuation thereof or on any separate record
maintained by such Lender. Failure to make any such notation or to attach a schedule
shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans
or affect the validity of such transfer by any Lender of its Note.

     Section 2.03 Requests for Borrowings To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by
telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, Eastern time, three
(3) Business Days before the date of the proposed Borrowing, or (b) in the case of an ABR
Borrowing, not later than 12:00 noon, Eastern time, on the date of the proposed Borrowing;
provided that no such notice shall be required for any deemed request of an ABR Borrowing
to finance the reimbursement of an LC

30

 

Disbursement as provided in Section 2.09(e). Each
such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand
delivery, facsimile or e-mail to the Administrative Agent of a written Borrowing Request in
substantially the form of Exhibit B and signed by the Borrower. Each such telephonic and
written Borrowing Request shall specify the following information in compliance with Section
2.02:

               (ii) the date of such Borrowing, which shall be a Business Day;

               (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

               (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable
thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and

               (v) the current total Credit Exposures (without regard to the requested Borrowing) and the pro
forma total Credit Exposures (giving effect to the requested Borrowing).

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an
ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar
Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one (1) month’s
duration. Each Borrowing Request shall constitute a representation that the amount of the
requested Borrowing shall not cause the total Credit Exposures to exceed the total Commitments.

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the
Administrative Agent shall advise each Lender of the details thereof and of the amount of such
Lender’s Loan to be made as part of the requested Borrowing.

     Section 2.04 Swingline Loans.

          (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make
Swingline Loans to the Borrower from time to time during the Availability Period, in an aggregate
principal amount at any time outstanding that will not result in (i) the aggregate principal amount
of outstanding Swingline Loans exceeding $25,000,000 or (ii) the
sum of the total Credit Exposures exceeding the total Commitments; provided that the
Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding
Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth
herein, the Borrower may borrow, prepay and reborrow Swingline Loans.

          (b) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such
request by telephone (confirmed by hand delivery, facsimile or e-mail), not later than 2:00 p.m.,
Eastern time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and
shall specify the requested date (which shall be a Business Day) and amount of the requested
Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such
notice received from the Borrower. The Swingline Lender shall make each

31

 

Swingline Loan available
to the Borrower by means of a credit to the general deposit account of the Borrower with the
Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC
Disbursement as provided in Section 2.09(e), by remittance to the applicable Issuing Bank)
by 4:00 p.m., Eastern time, on the requested date of such Swingline Loan.

          (c) The Swingline Lender may by written notice, given to the Administrative Agent not later
than 10:00 a.m., Eastern time, on any Business Day, require the Lenders to acquire participations
on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall
specify the aggregate amount of Swingline Loans in which Lenders will participate. Promptly upon
receipt of such notice, the Administrative Agent will give notice thereof to each Lender,
specifying in such notice such Lender’s Applicable Percentage of such Swingline Loan or Loans.
Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above,
to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s
Applicable Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that
its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute
and unconditional and shall not be affected by any circumstance whatsoever, including the
occurrence and continuance of a Default or reduction or termination of the Commitments, and that
each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.
Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately
available funds, in the same manner as provided in Section 2.06 with respect to Loans made
by such Lender (and Section 2.06 shall apply, mutatis mutandis, to the
payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the
Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall
notify the Borrower of any participations in any Swingline Loan acquired pursuant to this
paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the
Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender
from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after
receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be
promptly remitted to the Administrative Agent; any such amounts received by the Administrative
Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made
their payments pursuant to this paragraph and to the Swingline Lender, as their interests may
appear; provided that any such payment so remitted shall be repaid to the Swingline Lender
or to the Administrative Agent, as applicable, if and to the extent such payment is required to be
refunded to the Borrower for any
reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall
not relieve the Borrower of any default in the payment thereof.

     Section 2.05 Interest Elections.

          (a) Conversion and Continuance. Each Borrowing initially shall be of the Type
specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall
have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower
may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the
case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this
Section 2.05. The Borrower may elect different options with respect to different portions
of the affected Borrowing, in which case each such portion shall be allocated ratably

32

 

among the
Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion
shall be considered a separate Borrowing. This Section shall not apply to Swingline Borrowings,
which may not be converted or continued.

          (b) Interest Election Requests. To make an election pursuant to this Section
2.05, the Borrower shall notify the Administrative Agent of such election by telephone by the
time that a Borrowing Request would be required under Section 2.03 if the Borrower were
requesting a Borrowing of the Type resulting from such election to be made on the effective date of
such election. Each such telephonic Interest Election Request shall be irrevocable and shall be
confirmed promptly by hand delivery or facsimile to the Administrative Agent of a written Interest
Election Request in substantially the form of Exhibit C and signed by the Borrower.

          (c) Information in Interest Election Requests. Each telephonic and written Interest
Election Request shall specify the following information in compliance with Section 2.02:

               (i) the Borrowing to which such Interest Election Request applies and, if different options
are being elected with respect to different portions thereof, the portions thereof to be allocated
to each resulting Borrowing (in which case the information to be specified pursuant to Section
2.05(c)(iii) and (iv) shall be specified for each resulting Borrowing);

               (ii) the effective date of the election made pursuant to such Interest Election Request, which
shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period contemplated by
the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an
Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one (1)
month’s duration.

          (d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an
Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof
and of such Lender’s portion of each resulting Borrowing.

          (e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default on
Interest Election. If the Borrower fails to deliver a timely Interest Election Request with
respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then,
unless such Borrowing is repaid as provided herein, at the end of such Interest Period such
Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof,
if an Event of Default has occurred and is continuing: (i) no outstanding Borrowing may be
converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that
requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar

33

 

Borrowing shall be ineffective) and (ii) unless repaid, each Eurodollar Borrowing shall be
converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

     Section 2.06 Funding of Borrowings.

          (a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder
on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m., Eastern
time, to the account of the Administrative Agent most recently designated by it for such purpose by
notice to the Lenders; provided that Swingline Loans shall be made as provided in
Section 2.04. The Administrative Agent will make such Loans available to the Borrower by
promptly crediting the amounts so received, in like funds, to the account of the Borrower
designated by the Borrower in the Notice of Account Designation delivered to the Administrative
Agent on or prior to the Effective Date or to such other account designated by the Borrower in
writing to the Administrative Agent, or applicable Borrowing Request; provided that ABR
Loans made to finance the reimbursement of an LC Disbursement as provided in Section
2.09(e) shall be remitted by the Administrative Agent to the relevant Issuing Bank. Nothing
herein shall be deemed to obligate any Lender to obtain the funds for its 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 its Loan in any particular place or manner.

          (b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have
received notice from a Lender prior to the proposed time of any Borrowing (or prior to the proposed
time of any same day ABR Borrowing) that such Lender will not make available to the Administrative
Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender
has made such share available on such date in accordance with Section 2.06(a) and may, in
reliance upon such assumption, make available to the Borrower a corresponding amount. In such
event, if a Lender has not in fact made its share of the applicable Borrowing available to the
Administrative Agent, then the applicable Lender agrees to pay to the Administrative Agent
forthwith on demand such corresponding amount with interest thereon, for each day from and
including the date such amount is made available to the Borrower to but excluding the date of
payment to the Administrative Agent at the greater of the Federal Funds Effective Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules on interbank
compensation. If such Lender does not pay such corresponding
amount to the Administrative Agent within three (3) Business Days after demand, the Borrower
agrees to pay to the Administrative Agent forthwith on demand such corresponding amount with
interest thereon for each day from and including the date such amount is made available to the
Borrower to but excluding the date of payment to the Administrative Agent at the interest rate
applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such
amount shall constitute such Lender’s Loan included in such Borrowing.

     Section 2.07 Termination, Reduction and Increase of Commitments.

          (a) Mandatory Termination and Reduction of Commitments.

               (i) Unless previously terminated, all Commitments shall terminate on the earlier to occur of
(A) the Maturity Date and (B) any date specified pursuant to Section 10.02.

34

 

               (ii) The total Commitments shall automatically reduce by the amount of any mandatory
prepayments required pursuant to Sections 3.04(c)(ii) and (iii) on the date of each
such mandatory prepayment.

          (b) Optional Termination and Reduction of Commitments.

               (i) The Borrower may at any time terminate, or from time to time reduce, the total
Commitments; provided that (A) each reduction of the total Commitments shall be in an
amount that is an integral multiple of $1,000,000 and not less than $10,000,000 and (B) the
Borrower shall not terminate or reduce the total Commitments if, after giving effect to any
concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Credit
Exposures would exceed the total Commitments.

               (ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce
the total Commitments under Section 2.07(b)(i) at least three (3) Business Days prior to
the effective date of such termination or reduction, specifying such election and the effective
date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this
Section 2.07(b)(ii) shall be irrevocable; provided that a notice of termination of
the Commitments delivered by the Borrower may state that such notice is conditioned upon the
effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower
(by notice to the Administrative Agent on or prior to the specified effective date) if such
condition is not satisfied.

          (c) Terminations and Reductions of Commitments. Any termination or reduction of the
Commitments shall be permanent and may not be reinstated except pursuant to Section
2.07(d). Each reduction of the Commitments shall be made ratably among the Lenders in
accordance with each Lender’s Applicable Percentage.

          (d) Optional Increase in Commitments.

          (i) Subject to the conditions set forth in Section 2.07(d)(ii), the Borrower
may increase the total Commitments then in effect with the prior written consent of the
Administrative Agent by increasing the Commitment of a Lender or by causing a Person that at
such time is not a Lender to become a Lender (an “Additional Lender”).

          (ii) Any increase in the Commitments shall be subject to the following additional
conditions:

          (A) such increase shall not be less than $50,000,000 unless the Administrative
Agent otherwise consents; provided, that all such increases pursuant to this
Section 2.07(d) shall not exceed $200,000,000 in the aggregate;

          (B)
such increase shall occur prior to December 13, 2011;

          (C) no Default shall have occurred and be continuing at the effective date of
such increase;

35

 

          (D) the Borrower shall have paid all compensation required by Section
5.02 (if any);

          (E) no Lender’s Commitment may be increased without the consent of such Lender;

          (F) if the Borrower elects to increase the total Commitments by increasing the
Commitment of a Lender, the Borrower and such Lender shall execute and deliver to
the Administrative Agent a certificate substantially in the form of Exhibit
G-1 (a “Commitment Increase Certificate”), and if requested by such
Lender, the Borrower shall deliver a new Note payable to the order of such Lender in
a principal amount equal to its Commitment after giving effect to such increase, and
otherwise duly completed;

          (G) if the Borrower elects to increase the total Commitments by causing an
Additional Lender to become a party to this Agreement, then the Borrower and such
Additional Lender shall execute and deliver to the Administrative Agent a
certificate substantially in the form of Exhibit G-2 (an “Additional
Lender Certificate”), together with an Administrative Questionnaire, and if
requested by such Additional Lender, the Borrower shall deliver a Note payable to
the order of such Additional Lender in a principal amount equal to its Commitment,
and otherwise duly completed; and

          (H) the Borrower and its Restricted Subsidiaries shall have delivered to the
Administrative Agent such legal opinions, resolutions, amendment to Security
Instruments and other documents as the Administrative Agent may reasonably request.

          (iii) Subject to acceptance and recording thereof pursuant to Section
2.07(d)(iv), from and after the effective date specified in the Commitment Increase
Certificate or the Additional Lender Certificate: (A) the amount of the total
Commitments shall be increased as set forth therein, and (B) in the case of an Additional
Lender Certificate, any Additional Lender party thereto shall be a party to this Agreement
and the other Loan Documents and have the rights and obligations of a Lender under this
Agreement and the other Loan Documents. In addition, the Lender or the Additional Lender,
as applicable, shall purchase a pro rata portion of the outstanding Loans (and participation
interests in Letters of Credit) of each of the other Lenders (and such Lenders hereby agree
to sell and to take all such further action to effectuate such sale) such that each Lender
(including any Additional Lender, if applicable) shall hold its Applicable Percentage of the
outstanding Loans (and participation interests) after giving effect to the increase in the
total Commitments.

          (iv) Upon its receipt of a duly completed Commitment Increase Certificate or an
Additional Lender Certificate, executed by the Borrower and the Lender or the Borrower and
the Additional Lender party thereto, as applicable, the Administrative Questionnaire
referred to in Section 2.07(d)(ii), if applicable, the written consent of the
Administrative Agent to such increase required by Section 2.07(d)(i), and

36

 

all other
documents and payments required by this Section 2.07(d), the Administrative Agent
shall accept such Commitment Increase Certificate or Additional Lender Certificate and
record the information contained therein in the Register required to be maintained by the
Administrative Agent pursuant to Section 12.04(b)(iv).

     Section 2.08 Borrowing Base.

          (a) Initial Borrowing Base. For the period from and including the Effective Date to
but excluding the first Redetermination Date, the amount of the Borrowing Base shall be
$140,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further
adjustments from time to time pursuant to Section 8.13(c), Section 9.11(a) or
Section 9.12.

          (b) Borrowing Base Redeterminations. The Borrowing Base shall be redetermined
semi-annually in accordance with this Section 2.08 (a “Scheduled Redetermination”),
and subject to Section 2.08(d), such redetermined Borrowing Base shall become effective and
applicable to the Borrower, the Agents, any Issuing Bank and the Lenders on April 1st and October
1st of each year, commencing April 1, 2008. In addition, (a) the Borrowing Base shall be
redetermined as required by Section 9.02(h) and Section 9.02(m) and (b) the
Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at
the direction of the Required Lenders, by notifying the Borrower thereof, elect to cause the
Borrowing Base to be redetermined one time each between Scheduled Redeterminations, in the case of
clauses (a) and (b), in accordance with this Section 2.08 (each such redetermination, an
“Interim Redetermination”).

          (c) Borrowing Base Redetermination Procedure.

          (i) Each Borrowing Base Redetermination shall be effectuated as follows: Upon receipt
by the Administrative Agent of (A) the Reserve Report and the
certificate required to be delivered by the Borrower to the Administrative Agent, in
the case of a Scheduled Redetermination, pursuant to Section 8.12(a) and
(c), and, in the case of an Interim Redetermination, pursuant to Section
8.12(b) and (c), and (B) such other reports, data and supplemental information,
including, without limitation, the information provided pursuant to Section
8.12(c), as may, from time to time, be reasonably requested by the Majority Lenders
(the Reserve Report, such certificate and such other reports, data and supplemental
information being the “Engineering Reports”), the Administrative Agent shall
evaluate the information contained in the Engineering Reports and shall, in good faith,
propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such
information and such other information (including, without limitation, the status of title
information with respect to the Borrowing Base Properties as described in the Engineering
Reports and the existence of any other Indebtedness) as the Administrative Agent deems
appropriate in its sole discretion and consistent with its normal oil and gas lending
criteria as it exists at the particular time. In no event shall the Proposed Borrowing
Base exceed the total Commitments.

          (ii) The Administrative Agent shall notify the Borrower and the Lenders of the
Proposed Borrowing Base (the “Proposed Borrowing Base Notice”):

37

 

          (A) in the case of a Scheduled Redetermination (1) if the Administrative Agent
shall have received the Engineering Reports required to be delivered by the Borrower
pursuant to Section 8.12(a) and (c) in a timely and complete manner,
then on or before the March 15th and September 15th of such year following the date
of delivery, or (2) if the Administrative Agent shall not have received the
Engineering Reports required to be delivered by the Borrower pursuant to Section
8.12(a) and (c) in a timely and complete manner, then promptly after the
Administrative Agent has received complete Engineering Reports from the Borrower and
has had a reasonable opportunity to determine the Proposed Borrowing Base in
accordance with Section 2.08(c)(i); and

          (B) in the case of an Interim Redetermination, promptly, and in any event,
within fifteen (15) days after the Administrative Agent has received the required
Engineering Reports.

          (iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in
effect must be approved or deemed to have been approved by all of the Lenders as provided
in this Section 2.08(c)(iii); and any Proposed Borrowing Base that would decrease
or maintain the Borrowing Base then in effect must be approved or be deemed to have been
approved by the Required Lenders as provided in this Section 2.08(c)(iii). Upon
receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days to
agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by
proposing an alternate Borrowing Base. If at the end of such fifteen (15) days, any Lender
has not communicated its approval or disapproval in writing to the Administrative Agent,
such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the
end of such 15-day period, all of the Lenders, in the case of a Proposed Borrowing Base
that would increase the Borrowing Base then in effect, or the Required Lenders, in the case
of a Proposed Borrowing Base that would
decrease or maintain the Borrowing Base then in effect, have approved or deemed to
have approved, as aforesaid, then the Proposed Borrowing Base shall become the new
Borrowing Base, effective on the date specified in Section 2.08(d). If, however,
at the end of such 15-day period, all of the Lenders or the Required Lenders, as
applicable, have not approved or deemed to have approved, as aforesaid, then the
Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base then
acceptable to a number of Lenders sufficient to constitute the Required Lenders for
purposes of this Section 2.08 and, so long as such amount does not increase the
Borrowing Base then in effect, such amount shall become the new Borrowing Base, effective
on the date specified in Section 2.08(d).

          (d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing
Base is approved or is deemed to have been approved by all of the Lenders or the Required Lenders,
as applicable, pursuant to Section 2.08(c)(iii), the Administrative Agent shall notify the
Borrower and the Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing
Base Notice”), and such amount shall become the new Borrowing Base, effective and applicable to
the Borrower, the Agents, any Issuing Bank and the Lenders:

38

 

          (i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall
have received the Engineering Reports required to be delivered by the Borrower pursuant to
Section 8.12(a) and (c) in a timely and complete manner, then on the April
1st or October 1st, as applicable, following such notice, or (B) if the Administrative
Agent shall not have received the Engineering Reports required to be delivered by the
Borrower pursuant to Section 8.12(a) and (c) in a timely and complete
manner, then on the Business Day next succeeding delivery of such notice; and

          (ii) in the case of an Interim Redetermination or an adjustment to the Borrowing Base
under Section 8.13(c), Section 9.11(a) or Section 9.12, on the
Business Day next succeeding delivery of such notice.

Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the
next Interim Redetermination Date or the next adjustment to the Borrowing Base under Section
8.13(c), Section 9.11(a) or Section 9.12, whichever occurs first.
Notwithstanding the foregoing, no Borrowing Base Redetermination shall become effective until the
New Borrowing Base Notice related thereto is received by the Borrower.

     Section 2.09 Letters of Credit.

          (a) General. The Borrower, the Administrative Agent, the Issuing Bank, and Lenders
hereby agree that all Existing Letters of Credit shall be deemed to be issued under this Agreement
as of the Effective Date and shall constitute Letters of Credit hereunder for all purposes (except
that no Issuing Bank’s standard issuance fee shall be payable on such deemed issuance). Subject to
the terms and conditions set forth herein, the Borrower may request the issuance of dollar
denominated Letters of Credit for its own account or for the account of any of its Restricted
Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the
applicable Issuing Bank, at any time and from time to time during the Availability Period. In
the event of any inconsistency between the terms and conditions of this Agreement and the terms and
conditions of any Letter of Credit Agreement, the terms and conditions of this Agreement shall
control.

          (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request
the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter
of Credit), the Borrower shall hand deliver or facsimile (or transmit by electronic communication,
if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable
Issuing Bank and the Administrative Agent (not less than three (3) Business Days in advance of the
requested date of issuance, amendment, renewal or extension) a notice:

               (i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be
amended, renewed or extended;

               (ii) specifying the date of issuance, amendment, renewal or extension (which shall be a
Business Day);

39

 

               (iii) specifying the date on which such Letter of Credit is to expire (which shall comply with
Section 2.09(c));

               (iv) specifying the amount of such Letter of Credit;

               (v) specifying the name and address of the beneficiary thereof and such other information as
shall be necessary to prepare, amend, renew or extend such Letter of Credit; and

               (vi) specifying the current total Credit Exposures (without regard to the requested Letter of
Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the
pro forma total Credit Exposures (giving effect to the requested Letter of Credit or the requested
amendment, renewal or extension of an outstanding Letter of Credit).

Each notice shall constitute a representation that after giving effect to the requested issuance,
amendment, renewal or extension, as applicable, (i) the LC Exposure shall not exceed the LC
Commitment, and (ii) the total Credit Exposures shall not exceed the total Commitments.

If requested by an Issuing Bank, the Borrower also shall submit a letter of credit application on
such Issuing Bank’s standard form in connection with any request for a Letter of Credit.

          (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of
business on the earlier of (i) the date one (1) year after the date of the issuance of such Letter
of Credit, provided that such Letter of Credit may provide for automatic extensions of such
expiration date (such Letter of Credit, an “Auto-Extension Letter of Credit”) for
additional periods of 365 days thereafter, and (ii) the date that is five (5) Business Days prior
to the Maturity Date. The Borrower shall be required to make a specific request to the applicable
Issuing Bank for any extension of an Auto-Extension Letter of Credit. Once an Auto-Extension
Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not
require) the applicable Issuing Bank to permit the extension of such Letter of Credit at any
time to an expiry date not later than five (5) Business Days prior to the Maturity Date;
provided, however, that such Issuing Bank shall not permit any such extension if
(A) such Issuing Bank has determined that it would not be permitted at such time to issue such
Letter of Credit in its revised form (as extended) under the terms hereof, or (B) it has received
notice (which may be by telephone or in writing) from the Administrative Agent, on or before the
day that is five (5) Business Days before the last day in which notice of non-extension for such
Letter of Credit may be given, that one or more of the applicable conditions specified in
Section 6.02 is not then satisfied, and directing such Issuing Bank not to permit such
extension.

          (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of any
Issuing Bank or the Lenders, the applicable Issuing Bank hereby grants to each Lender, and each
Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to
such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter
of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the applicable
Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement

40

 

made by such Issuing Bank
and not reimbursed by the Borrower on the date due as provided in Section 2.09(e), or of
any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender
acknowledges and agrees that its obligation to acquire participations pursuant to this Section
2.09(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected
by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default, the existence of a Borrowing Base Deficiency
or reduction or termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

          (e) Reimbursement. If any Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative
Agent an amount equal to such LC Disbursement not later than 12:00 noon, Eastern time, on the date
that such LC Disbursement is made, if the Borrower shall have received notice of such LC
Disbursement prior to 10:00 a.m., Eastern time, on such date, or, if such notice has not been
received by the Borrower prior to such time on such date, then not later than 12:00 noon, Eastern
time, on (i) the Business Day that the Borrower receives such notice, if such notice is received
prior to 10:00 a.m., Eastern time, on the day of receipt, or (ii) the Business Day immediately
following the day that the Borrower receives such notice, if such notice is not received prior to
such time on the day of receipt; provided that the Borrower shall, subject to the
conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby
request under such circumstances, that such payment be financed with an ABR Borrowing (or, if such
LC Disbursement is less than $1,000,000, a Swingline Loan) in an equivalent amount and, to the
extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced
by the resulting ABR Borrowing (or Swingline Loan). If the Borrower fails to make such payment
when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the
payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage
thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative
Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as
provided in Section 2.05(a) with
respect to Loans made by such Lender (and Section 2.05(a) shall apply, mutatis
mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly
pay to such Issuing Bank the amounts so received by it from the Lenders. Promptly following
receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section
2.09(e), the Administrative Agent shall distribute such payment to such Issuing Bank or, to the
extent that Lenders have made payments pursuant to this Section 2.09(e) to reimburse such
Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any
payment made by a Lender pursuant to this Section 2.09(e) to reimburse such Issuing Bank
for any LC Disbursement (other than the funding of ABR Loans or a Swingline Loan as contemplated
above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to
reimburse such LC Disbursement.

          (f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as
provided in Section 2.09(e) shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit,
any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft
or other document presented under a Letter of Credit proving to be forged,

41

 

fraudulent or invalid in
any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by
any Issuing Bank under a Letter of Credit against presentation of a draft or other document that
does not substantially comply with the terms of such Letter of Credit or any Letter of Credit
Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the
foregoing, that might, but for the provisions of this Section 2.09(f), constitute a legal
or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations
hereunder, absent such Issuing Bank’s gross negligence or willful misconduct. Neither the
Administrative Agent, the Lenders nor any Issuing Bank, nor any of their Related Parties shall have
any liability or responsibility by reason of or in connection with the issuance or transfer of any
Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of
the circumstances referred to in the preceding sentence), or any error, omission, interruption,
loss or delay in transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a drawing thereunder),
any error in interpretation of technical terms or any consequence arising from causes beyond the
control of any Issuing Bank; provided that the foregoing shall not be construed to excuse
such Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the Borrower to the extent
permitted by applicable law) suffered by the Borrower that are caused by such Issuing Bank’s
failure to exercise care when determining whether drafts and other documents presented under a
Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the
absence of gross negligence or willful misconduct on the part of any Issuing Bank (as finally
determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have
exercised all requisite care in each such determination. In furtherance of the foregoing and
without limiting the generality thereof, the parties agree that, with respect to documents
presented which appear on their face to be in substantial compliance with the terms of a Letter of
Credit, such Issuing Bank may, in its sole discretion, either accept and make payment upon such
documents without responsibility for further investigation, regardless of any notice or information
to the contrary, or refuse to accept and make payment
upon such documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

          (g) Disbursement Procedures. The applicable Issuing Bank shall, promptly following
its receipt thereof, examine all documents purporting to represent a demand for payment under a
Letter of Credit. Such Issuing Bank shall promptly notify the Administrative Agent and the
Borrower by telephone (confirmed by facsimile) of such demand for payment and whether such Issuing
Bank has made or will make an LC Disbursement thereunder; provided that any failure to give
or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such
Issuing Bank and the Lenders with respect to any such LC Disbursement.

          (h) Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, until
the Borrower shall have reimbursed such Issuing Bank for such LC Disbursement (either with its own
funds or a Borrowing under Section 2.09(e)), the unpaid amount thereof shall bear interest,
for each day from and including the date such LC Disbursement is made to but excluding the date
that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR
Loans. Interest accrued pursuant to this Section 2.09(h) shall be for the account of the
applicable Issuing Bank, except that interest accrued on and after the date

42

 

of payment by any
Lender pursuant to Section 2.09(e) to reimburse such Issuing Bank shall be for the account
of such Lender to the extent of such payment.

          (i) Replacement of an Issuing Bank. Any Issuing Bank may be replaced at any time by
written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the
successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement
of the replaced Issuing Bank. At the time any such replacement shall become effective, the
Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to
Section 3.05(b). From and after the effective date of any such replacement, (i) the
successor Issuing Bank shall have all the rights and obligations of an Issuing Bank under this
Agreement with respect to Letters of Credit to be issued by it thereafter and (ii) references
herein to the term “Issuing Bank” shall be deemed to refer to such successor and any other existing
Issuing Banks or to any previous Issuing Bank, or to such successor and all other existing Issuing
Banks and previous Issuing Banks, as the context shall require. After the replacement of an
Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to
have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters
of Credit issued by it prior to such replacement, but shall not be required to issue additional
Letters of Credit.

          (j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing
and the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding
the deposit of cash collateral pursuant to this Section 2.09(j), or (ii) the Borrower is
required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection
with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an
account with the Administrative Agent, in the name of the Administrative Agent and for the benefit
of the Lenders, an amount in cash equal to, in the case of an Event of Default, the LC Exposure,
and in the case of a payment required by Section 3.04(c), the amount of such excess as
provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon;
provided that the obligation to deposit such cash collateral shall become
effective immediately, and such deposit shall become immediately due and payable, without
demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the
Borrower or any Restricted Subsidiary described in Section 10.01(i) or Section
10.01(j). The Borrower hereby grants to the Administrative Agent, for the benefit of the
Issuing Banks and the Lenders, an exclusive first priority and continuing perfected security
interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if
any, from time to time deposited or held in such account, all deposits or wire transfers made
thereto, any and all investments purchased with funds deposited in such account, all interest,
dividends, cash, instruments, financial assets and other Property from time to time received,
receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and
all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any
substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to
this Section 2.09(j) 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 Borrower or any of its Subsidiaries may now or hereafter have against any such
beneficiary, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any
reason whatsoever.

43

 

Such deposit shall be held as collateral securing the payment and performance
of the Borrower’s and the Guarantor’s obligations under this Agreement and the other Loan
Documents. The Administrative Agent shall have exclusive dominion and control, including the
exclusive right of withdrawal, over such account. Other than any interest earned on the investment
of such deposits, which investments shall be made at the option and sole discretion of the
Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest.
Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such
account shall be applied by the Administrative Agent to reimburse the Issuing Banks for LC
Disbursements for which they have not been reimbursed and, to the extent not so applied, shall be
held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at
such time, and if such moneys shall exceed the LC Exposure at any time, such excess shall be
reimbursed to the Borrower. If the Borrower is required to provide an amount of cash collateral
hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise
required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection
with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not
applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all
Events of Default have been cured or waived.

ARTICLE III

Payments of Principal and Interest; Prepayments; Fees

     Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account
of each Lender the then unpaid principal amount of each Loan on the Termination Date.

     Section 3.02 Interest.

          (a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the
Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear
interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (c) Swingline Loans. Each Swingline Loan shall bear interest at the LIBOR Reference
Rate plus the Applicable Margin for a Eurodollar Borrowing, but in no event to exceed the Highest
Lawful Rate.

          (d) Post-Default Rate. Notwithstanding the foregoing, if an Event of Default has
occurred and is continuing, or if any principal of or interest on any Loan or any fee or other
amount payable by the Borrower or any Guarantor hereunder or under any other Loan Document is not
paid when due, whether at stated maturity, upon acceleration or otherwise, then all Loans
outstanding, in the case of an Event of Default, and such overdue amount, in the case of a failure
to pay amounts when due, shall bear interest, after as well as before judgment, at a rate per annum
equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section
3.02(a), but in no event to exceed the Highest Lawful Rate, all Loans outstanding at such time

44

 

shall bear interest, after as well as before judgment, at the rate then applicable to such Loans,
plus the Applicable Margin, if any, plus an additional two percent (2%), but in no event to exceed
the Highest Lawful Rate.

          (e) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and on the Termination Date; provided that (i)
interest accrued pursuant to Section 3.02(d) shall be payable on demand, (ii) in the event
of any repayment or prepayment of any Loan (other than an optional prepayment of an ABR Loan prior
to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be
payable on the date of such repayment or prepayment, and (iii) in the event of any conversion of
any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on
such Loan shall be payable on the effective date of such conversion.

          (f) Interest Rate Computations. All interest hereunder shall be computed on the basis
of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case
interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except
that interest computed by reference to the Alternate Base Rate at times when the Alternate Base
Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days
in a leap year), and in each case shall be payable for the actual number of days elapsed (including
the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate
or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error, and be binding upon the parties hereto.

     Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO
Rate or the LIBO Rate for such Interest Period; or

          (b) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or
LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost
to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest
Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or facsimile as promptly as practicable thereafter and, until the Administrative Agent
notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer
exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any
Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR
Borrowing.

     Section 3.04 Prepayments.

          (a) Optional Prepayments. The Borrower shall have the right at any time and from time
to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with
Section 3.04(b).

45

 

          (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the
Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by
telephone (confirmed by facsimile or other electronic transmission) of any prepayment hereunder not
later than 12:00 noon, Eastern time, on the date of prepayment. Each such notice shall be
irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or
portion thereof to be prepaid; provided that, if a notice of prepayment is given in
connection with a conditional notice of termination of the Commitments as contemplated by
Section 2.07(b), then such notice of prepayment may be revoked if such notice of
termination is revoked in accordance with Section 2.07(b). Promptly following receipt of
any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the
contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be
permitted in the case of an advance of a Borrowing of the same Type as provided in Section
2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the
prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by
Section 3.02.

          (c) Mandatory Prepayments.

               (i) If, after giving effect to any termination or reduction of the total Commitments pursuant
to Section 2.07(b), the total Credit Exposures exceeds the total Commitments, then the
Borrower shall make a prepayment in accordance with Section 3.04(c)(vi) on the date of such
termination or reduction in an aggregate principal amount equal to such excess.

               (ii) On each date on or after the Effective Date upon which the Borrower or any Restricted
Subsidiary receives any cash proceeds from any Asset Sale made pursuant to Section 9.12(k),
an amount equal to 100% of the Net Sale Proceeds therefrom shall be applied on such date as a
mandatory repayment and/or commitment reduction in accordance with Section 3.04(c)(vi);
provided, however, that such Net Sale Proceeds shall not be required to be so
applied on such date so long as no Event of Default then exists and such Net Sale Proceeds shall be
used to purchase Property (other than inventory and working capital) used or to be used in the
businesses permitted pursuant to Section 9.07 within 270 days following the date of such
Asset Sale, and provided further, that if all or any portion of such Net Sale
Proceeds not required to be so applied as provided above in this Section 3.04(c)(ii) are
not so reinvested within such 270 day period (or such earlier date, if any, as the Borrower or
relevant Restricted Subsidiary determines not to reinvest the Net Sale Proceeds from such Asset
Sale as set forth above), such remaining portion shall be applied on the last day of such period
(or such earlier date, as the case may be) as provided above in this Section 3.04(c)(ii)
without regard to the preceding proviso.

               (iii) On each date on or after the Effective Date upon which the Borrower or any Restricted
Subsidiary receives any cash proceeds from any Recovery Event (other than Recovery Events where the
Net Cash Proceeds therefrom do not exceed five percent (5%) of Consolidated Net Tangible Assets),
an amount equal to 100% of the Net Cash Proceeds from such Recovery Event shall be applied on such
date as a mandatory repayment in accordance with the requirements of Section 3.04(c)(vi);
provided, however, that so long as no Event of Default then exists, such Net Cash
Proceeds shall not be required to be so applied on such date to the extent that such Net Cash
Proceeds shall be used to replace or restore any

46

 

Property in respect of which such Net Cash
Proceeds were paid within 270 days following the date of the receipt of such Net Cash Proceeds, and
provided further, that if all or any portion of such Net Cash Proceeds are not so
used within 270 days after the date of the receipt of such Net Cash Proceeds (or such earlier date,
if any, as the Borrower or relevant Restricted Subsidiary determines not to reinvest the Net Cash
Proceeds relating to such Recovery Event as set forth above), such remaining portion shall be
applied on the last day of such period (or such earlier date, as the case may be) as provided above
in this Section 3.04(c)(iii) without regard to the proviso or the immediately preceding
proviso.

               (iv) On each date on or after the Effective Date upon which (A) the Borrower or any Restricted
Subsidiary receives any cash proceeds from a sale or other disposition of any interest in any
Borrowing Base Properties or a Restricted Subsidiary owning any Borrowing Base Properties pursuant
to Section 9.12(f), and (B) a Borrowing Base Deficiency exists or results therefrom, an
amount equal to 100% of the Net Sale Proceeds therefrom (up to the amount of the Borrowing Base
Deficiency) shall be applied on such date as a mandatory repayment in accordance with the
requirements of Section 3.04(c)(vi); provided, that if a Borrowing Base Deficiency
continues to exist after such mandatory repayment, (1) the Borrower shall, subject to the
conditions in Section 6.02, be deemed to have requested, and the Borrower does hereby
request under such circumstances, that an amount equal to such remaining Deficiency Amount (or such
lesser amount equal to the amount of the Commitments then available for Non-Borrowing Base
Indebtedness) be transferred from Borrowing Base Indebtedness to Non-Borrowing Base Indebtedness
and that the Deficiency Amount be reduced by an amount equal to the amount of Borrowing Base
Indebtedness transferred to Non-
Borrowing Base Indebtedness, and (2) the Borrower shall make a mandatory prepayment in an
amount equal to the balance of such Deficiency Amount in accordance with Section
3.04(c)(vi).

               (v) If a Borrowing Base Deficiency results from or exists immediately after any adjustment to
the Borrowing Base pursuant to Section 2.08, Section 8.13(c) or Section
9.11(a) (but not in connection with an adjustment as a result of Section 9.12(f)), the
Borrower shall, subject to the conditions in Section 6.02, be deemed to have requested, and
the Borrower does hereby request under such circumstances, that an amount equal to such Deficiency
Amount (or such lesser amount equal to the amount of the Commitments then available for
Non-Borrowing Base Indebtedness) be transferred from Borrowing Base Indebtedness to Non-Borrowing
Base Indebtedness and that the Deficiency Amount be reduced by an amount equal to the amount of
Borrowing Base Indebtedness transferred to Non-Borrowing Base Indebtedness. The Borrower shall (A)
make mandatory prepayments within six (6) months of such Borrowing Base adjustment (in six (6)
equal monthly installments) in an aggregate amount equal to the balance of such Deficiency Amount
in accordance with Section 3.04(c)(vi), or (B) grant Liens to the Administrative Agent in
accordance with Section 8.14(a) on additional Oil and Gas Properties of the Loan Parties
that are not Royalty Properties that (1) are not Borrowing Base Properties, and (2) are
satisfactory to the Administrative Agent and are deemed by the Administrative Agent to have a value
equal to or in excess of such balance of the Deficiency Amount.

               (vi) Each payment made pursuant to this Section 3.04(c) shall be used to prepay the
Borrowings, and if any excess remains after prepaying all of the Borrowings as a result of an LC
Exposure, such excess shall be paid to the Administrative Agent on behalf of the

47

 

Lenders to be held
as cash collateral as provided in Section 2.09(j). Each prepayment of Borrowings pursuant
to this Section 3.04(c) shall be applied, first, to any Swingline Loans then outstanding,
second, ratably to any ABR Borrowings then outstanding, and, third, to any Eurodollar Borrowings
then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such
Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least
number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar
Borrowing with the most number of days remaining in the Interest Period applicable thereto.

     (vii) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied
ratably to the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section
3.04(c) shall be accompanied by accrued interest to the extent required by Section
3.02.

          (d) No Premium or Penalty. Prepayments permitted or required under this Section
3.04 shall be without premium or penalty, except as required under Section 5.02.

     Section 3.05 Fees.

          (a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the
account of each Lender a commitment fee, which shall accrue at the applicable
Commitment Fee Rate on the average daily amount of the unused amount of the Commitment of such
Lender during the period from and including the date of this Agreement to but excluding the
Termination Date; provided that for purposes of calculating commitment fees pursuant to
this Section 3.05(a), Swingline Loans shall not be deemed to be a utilization of
Commitments. Accrued commitment fees shall be payable in arrears on the last day of March, June,
September and December of each year and on the Termination Date, commencing on the first such date
to occur after the date hereof. All commitment fees shall be computed on the basis of a year of
360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest
shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be
payable for the actual number of days elapsed (including the first day but excluding the last day).

          (b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent
for the account of each Lender a participation fee with respect to its participations in Letters of
Credit, which shall accrue at the same Applicable Margin used to determine the interest rate
applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding
any portion thereof attributable to unreimbursed LC Disbursements) during the period from and
including the date of this Agreement to but excluding the later of the date on which such Lender’s
Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to the
applicable Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the
average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed
LC Disbursements) during the period from and including the date of this Agreement to but excluding
the later of the date of termination of the Commitments and the date on which there ceases to be
any LC Exposure, provided that in no event shall such fee be less than $500 during any
quarter, and (iii) to the applicable Issuing Bank, for its own account, its standard fees with
respect to the amendment, renewal or extension of any Letter of Credit or processing of drawings
thereunder. Participation

48

 

fees and fronting fees accrued through and including the last day of
March, June, September and December of each year shall be payable on the third (3rd)
Business Day following such last day, commencing on the first such date to occur after the date of
this Agreement; provided that all such fees shall be payable on the Termination Date and
any such fees accruing after the Termination Date shall be payable on demand. Any other fees
payable to any Issuing Bank pursuant to this Section 3.05(b) shall be payable within ten
(10) days after demand. All participation fees and fronting fees shall be computed on the basis of
a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case
interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and
shall be payable for the actual number of days elapsed (including the first day but excluding the
last day).

          (c) Administrative Agent Fees. The Borrower agrees to pay to the Administrative
Agent, for its own account, fees payable in the amounts and at the times separately agreed upon
between the Borrower and the Administrative Agent.

ARTICLE IV

Payments; Pro Rata Treatment; Sharing of Set-offs.

     Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

          (a) Payments by the Borrower. The Borrower shall make each payment required to be
made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or
of amounts payable under Section 5.01, Section 5.02, Section 5.03 or
otherwise) prior to 12:00 noon, Eastern time, on the date when due, in immediately available funds,
without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully
earned and shall not be refundable under any circumstances. Any amounts received after such time
on any date may, in the discretion of the Administrative Agent, be deemed to have been received on
the next succeeding Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices specified in Section 12.01, except
payments to be made directly to any Issuing Bank as expressly provided herein and except that
payments pursuant to Section 5.01, Section 5.02, Section 5.03 and
Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative
Agent shall distribute any such payments received by it for the account of any other Person to the
appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on
a day that is not a Business Day, the date for payment shall be extended to the next succeeding
Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable
for the period of such extension. All payments hereunder shall be made in dollars.

          (b) Application of Insufficient Payments. If at any time insufficient funds are
received by and available to the Administrative Agent to pay fully all amounts of principal,
unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, towards payment of interest and fees then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to such parties, and
(ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of principal and
unreimbursed LC Disbursements then due to such parties.

49

 

          (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of
set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on
any of its Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender
receiving payment of a greater proportion of the aggregate amount of its Loans and participations
in LC Disbursements or Swingline Loans and accrued interest thereon than the proportion received by
any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at
face value) participations in the Loans and participations in LC Disbursements of other Lenders to
the extent necessary so that the benefit of all such payments shall be shared by the Lenders
ratably in accordance with the aggregate amount of principal of and accrued interest on their
respective Loans and participations in LC Disbursements and Swingline Loans; provided that
(i) if any such participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase price restored to the
extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c)
shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance
with the express terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loans or participations in LC
Disbursements and Swingline Loans to any assignee or participant, other than to the Borrower or any
Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall
apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Lender acquiring a participation pursuant to
the foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were a direct creditor
of the Borrower in the amount of such participation.

     Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date
on which any payment is due to the Administrative Agent for the account of the Lenders or any
Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that
the Borrower has made such payment on such date in accordance herewith and may, in reliance upon
such assumption, distribute to the Lenders or the applicable Issuing Bank, as the case may be, the
amount due. In such event, if the Borrower has not in fact made such payment, then each of the
Lenders or the applicable Issuing Bank, as the case may be, severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing
Bank with interest thereon, for each day from and including the date such amount is distributed to
it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal
Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation.

     Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section
2.06(b), Section 2.09(d), Section 2.09(e) or Section 4.02 then the
Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply
any amounts thereafter received by the Administrative Agent for the account of such Lender to
satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are
fully paid.

     Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower and/or the Guarantors unto and in
favor of the Administrative Agent for the

50

 

benefit of the Lenders of all of the Borrower’s or each
Guarantor’s interest in and to production and all proceeds attributable thereto which may be
produced from or allocated to the Borrowing Base Properties. The Security Instruments further
provide in general for the application of such proceeds to the satisfaction of the Secured
Obligations and other obligations described therein and secured thereby. Notwithstanding the
assignment contained in such Security Instruments, until the occurrence of an Event of Default, (a)
the Administrative Agent and the Lenders agree that they will neither notify the purchaser or
purchasers of such production nor take any other action to cause such proceeds to be remitted to
the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be
paid to the Borrower and its Restricted Subsidiaries and (b) the Lenders hereby authorize the
Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to
the Borrower and/or such Restricted Subsidiaries.

ARTICLE V

Increased Costs; Break Funding Payments; Taxes; Illegality

     Section 5.01 Increased Costs.

          (a) Eurodollar Changes in Law. If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special deposit or similar requirement
against assets of, deposits with or for the account of, or credit extended by, any Lender (except
any such reserve requirement reflected in the Adjusted LIBO Rate); or

               (ii) impose on any Lender or the London interbank market any other condition affecting this
Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to
reduce the amount of any sum received or receivable by such Lender (whether of principal, interest
or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered; provided
that the Borrower shall have no obligation to pay any such costs incurred or suffered more than six
(6) months prior to the demand therefor; provided further that, if the Change in
Law giving rise to such increased costs or reductions is retroactive, then the six-month period
referred to above shall be extended to include the period of retroactive effect thereof.

          (b) Capital Requirements. If any Lender or any Issuing Bank determines that any
Change in Law regarding capital requirements has or would have the effect of reducing the rate of
return on such Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or such
Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or
participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by such
Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such
Issuing Bank’s holding company could have achieved but for such Change in Law (taking into
consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or
such Issuing Bank’s holding company with respect to capital adequacy), then from time to time the
Borrower will pay to such Lender or such Issuing Bank, as

51

 

the case may be, such additional amount
or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing
Bank’s holding company for any such reduction suffered; provided that the Borrower shall
have no obligation to pay any such costs incurred or suffered more than six (6) months prior to the
demand therefor; provided further that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the six-month period referred to above shall be
extended to include the period of retroactive effect thereof.

          (c) Certificates. A certificate of a Lender or an Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company,
as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to
the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or
such Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten
(10) days after receipt thereof.

          (d) Effect of Failure or Delay in Requesting Compensation. Except as provided above,
failure or delay on the part of any Lender or any Issuing Bank to demand
compensation pursuant to this Section 5.01 shall not constitute a waiver of such
Lender’s or such Issuing Bank’s right to demand such compensation.

     Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last
day of an Interest Period applicable thereto (including as a result of an Event of Default), (b)
the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest
Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar
Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any
Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of
a request by the Borrower pursuant to Section 5.04(b), then, in any such event, the
Borrower shall compensate each Lender for the loss, cost and expense attributable to such event.
In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to
include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest
which would have accrued on the principal amount of such Loan had such event not occurred, at the
Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of
such event to the last day of the then current Interest Period therefor (or, in the case of a
failure to borrow, convert or continue, for the period that would have been the Interest Period for
such Loan), over (ii) the amount of interest which would accrue on such principal amount for such
period at the interest rate which such Lender would bid were it to bid, at the commencement of such
period, for dollar deposits of a comparable amount and period from other banks in the eurodollar
market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section 5.02 shall be delivered to the Borrower and shall be
conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on
any such certificate within ten (10) days after receipt thereof.

     Section 5.03 Taxes.

          (a) Payments Free of Taxes. Any and all payments by or on account of any obligation
of the Borrower or any Guarantor under any Loan Document shall be made free and

52

 

clear of and
without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower
or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such
payments, then (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 5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be)
receives an amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower or such Guarantor shall make such deductions and (iii) the Borrower or such
Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance
with applicable law.

          (b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law.

          (c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative
Agent, each Lender and each Issuing Bank, within ten (10) days after written demand therefor, for
the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such
Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account
of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section 5.03) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate of the Administrative Agent, a Lender or an Issuing Bank as
to the amount of such payment or liability under this Section 5.03 shall be delivered to
the Borrower and shall be conclusive absent manifest error.

          (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority, the Borrower 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.

          (e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or
any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or
any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and executed documentation
prescribed by applicable law or reasonably requested by the Borrower as will permit such payments
to be made without withholding or at a reduced rate.

          (f) Tax Refunds. If the Administrative Agent or a Lender 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 Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this Section 5.03, it shall pay over such refund to the Borrower (but only to
the extent of indemnity payments made, or additional amounts paid, by the Borrower under this
Section 5.03 with respect to the Taxes or Other Taxes giving rise to such refund), net of
all out-of-pocket

53

 

expenses of the Administrative Agent or such Lender and without interest (other
than any interest paid by the relevant Governmental Authority with respect to such refund);
provided, that the Borrower, upon the request of the Administrative Agent or such Lender,
agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the
event the Administrative Agent or such Lender is required to repay such refund to such Governmental
Authority. This Section 5.03 shall not be construed to require the Administrative Agent or
any Lender to make available its tax returns (or any other information relating to its taxes which
it deems confidential) to the Borrower or any other Person.

     Section 5.04 Mitigation Obligations; Replacement of Lenders.

          (a) Designation of Different Lending Office. If any Lender requests compensation
under Section 5.01, or if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to Section
5.03, then such Lender shall use reasonable efforts to designate a different lending office for
funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another
of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or
Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to
any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The
Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

          (b) Replacement of Lenders. If (i) any Lender requests compensation under Section
5.01, (ii) the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 5.03, (iii) any
Lender defaults in its obligation to fund Loans hereunder, (iv) any Lender declines to make a
Eurodollar Loan under Section 5.05 or (v) any Lender declines to enter into any amendment
hereto executed and delivered by the Required Lenders, then the Borrower may, at its 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
Section 12.04(b)), all its interests, rights and obligations under this Agreement to an
assignee that shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (i) the Borrower shall have received the prior
written consent of the Administrative Agent, which consent shall not unreasonably be withheld, and
(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its
Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other
amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts).

     Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for
any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar
Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall
promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to
make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as
such Lender may again make and

54

 

maintain such Eurodollar Loans and (b) all Affected Loans which
would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so
requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender
then outstanding shall be automatically converted into ABR Loans on the date specified by such
Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into)
ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected
Loans shall be applied instead to its ABR Loans.

ARTICLE VII

Representations and Warranties

     The Borrower (on behalf of itself and its Subsidiaries), and each Guarantor by its execution
of a Guaranty and Collateral Agreement, represents and warrants to the Administrative Agent, the
Issuing Banks and the Lenders that:

     Section 7.01 Organization; Powers. Each of the Borrower and the Restricted Subsidiaries is a legal entity duly organized, validly
existing and in good standing under the laws of the jurisdiction of its organization, has all
requisite power and authority, and has all material governmental licenses, authorizations, consents
and approvals necessary, to own its assets and to carry on its business as now conducted, and is
qualified to do business in, and is in good standing in, every jurisdiction where such
qualification is required, except where failure to have such power, authority, licenses,
authorizations, consents, approvals and qualifications could not reasonably be expected to have a
Material Adverse Effect.

     Section 7.02 Authority; Enforceability. The Transactions are within each Loan Party’s corporate powers and have been duly authorized by
all necessary corporate and, if required, stockholder action (including, without limitation, any
action required to be taken by any class of directors of the Borrower or any other Person, whether
interested or disinterested, in order to ensure the due authorization of the Transactions). Each
Loan Document to which a Loan Party is a party has been duly executed and delivered by such Loan
Party and constitutes a legal, valid and binding obligation of such Loan Party, enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium
or other laws affecting creditors’ rights generally and subject to general principles of equity,
regardless of whether considered in a proceeding in equity or at law.

     Section 7.03 Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or
any other action by, any Governmental Authority or any other third Person (including shareholders
or any class of directors, whether interested or disinterested, of the Borrower or any other
Person), nor is any such consent, approval, registration, filing or other action necessary for the
validity or enforceability of any Loan Document or the consummation of the transactions
contemplated thereby, except such as have been obtained or made and are in full force and effect
other than (i) the recording and filing of the Security Instruments as required by this Agreement
and (ii) those third party approvals or consents which, if not made or obtained, would not cause a
Default hereunder, could not

58

 

reasonably be expected to have a Material Adverse Effect or do not
have an adverse effect on the enforceability of the Loan Documents, (b) will not violate any
applicable law or regulation or any Organization Document of the Borrower or any Restricted
Subsidiary or any order of any Governmental Authority, (c) will not violate or result in a default
under any indenture, agreement or other instrument binding upon the Borrower or any Restricted
Subsidiary or its Properties, or give rise to a right thereunder to require any payment to be made
by the Borrower or such Restricted Subsidiary and (d) will not result in the creation or imposition
of any Lien on any Property of the Borrower or any Restricted Subsidiary (other than the Liens
created by the Loan Documents).

     Section 7.04 Financial Condition; No Material Adverse Change.

          (a) The Borrower has heretofore furnished to the Lenders its consolidated balance sheet and
statements of income, stockholders equity and cash flows (i) contained in its Form 10-K as of and
for the fiscal year ended 2006 filed with the SEC, with a report by Deloitte & Touche LLP,
independent public accountants, and (ii) as contained in its Form 10-Q as of and for each fiscal
quarter and the portion of such fiscal year ended March 31, 2007, June 30, 2007 and September 30,
2007 filed with the SEC. Such Financial Statements present fairly, in all material respects, the
financial position and results of operations and cash flows of the Borrower and its Consolidated
Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year-end
audit adjustments and the absence of footnotes in the case of the unaudited quarterly Financial
Statements.

          (b) Since December 31, 2006, (i) there has been no event, development or circumstance that has
had or could reasonably be expected to have a Material Adverse Effect and (ii) the business of the
Borrower and its Restricted Subsidiaries has been conducted only in the ordinary course consistent
with past business practices.

          (c) Neither the Borrower nor any Restricted Subsidiary has on the date hereof any material
Indebtedness (including Disqualified Capital Stock) or any contingent liabilities, off-balance
sheet liabilities or partnerships, liabilities for taxes, unusual forward or long-term commitments
or unrealized or anticipated losses from any unfavorable commitments, except as referred to or
reflected or provided for in the Financial Statements.

          (d) The projections regarding the financial performance of the Borrower and its Consolidated
Subsidiaries furnished to the Lenders have been prepared in good faith by the Borrower and based
upon assumptions believed by the Borrower to be reasonable at the time such projections were
provided (and on the Effective Date in the case of forecasts provided prior to the Effective Date)
(it being recognized by the Lenders, however, that projections as to future events are not to be
viewed as facts and that actual results during the period(s) covered by such projections may differ
from the projected results and that such differences may be material and that the Loan Parties make
no representation that such projections will be realized).

     Section 7.05 Litigation.

          (a) Except as set forth on Schedule 7.05, there are no actions, suits, investigations
or proceedings by or before any arbitrator or Governmental Authority pending

59

 

against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or
any Restricted Subsidiary or any of their Properties (i) as to which there is a reasonable
possibility of an adverse determination that, if adversely determined, could reasonably be
expected, individually or in the aggregate, to result in a Material Adverse Effect, or (ii) that
involve any Loan Document or the Transactions.

          (b) Since the date of this Agreement, there has been no change in the status of the matters
disclosed in Schedule 7.05 that, individually or in the aggregate, has resulted in, or
materially increased the likelihood of, a Material Adverse Effect.

     Section 7.06 Environmental Matters.
Except for such matters as set forth on Schedule 7.06 or that, individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect:

          (a) the Borrower and the Restricted Subsidiaries and each of their respective Properties and
operations thereon are, and within all applicable statute of limitation periods have been, in
compliance with all applicable Environmental Laws;

          (b) the Borrower and the Restricted Subsidiaries have obtained all Environmental Permits
required for their respective operations and each of their Properties, with all such Environmental
Permits being currently in full force and effect, and none of Borrower or the Restricted
Subsidiaries has received any written notice or otherwise has knowledge that any such existing
Environmental Permit will be revoked or that any application for any new Environmental Permit or
renewal of any existing Environmental Permit will be protested or denied;

          (c) there are no claims, demands, suits, orders, inquiries, investigations, requests for
information or proceedings concerning any violation of, or any liability (including as a
potentially responsible party) under, any applicable Environmental Law that is pending or, to the
Borrower’s knowledge, threatened against the Borrower or any Restricted Subsidiary or any of their
respective Properties or as a result of any operations at such Properties;

          (d) none of the Properties of the Borrower or any Restricted Subsidiary contain or have
contained any: (i) underground storage tanks; (ii) asbestos-containing materials; (iii) landfills
or dumps; (iv) hazardous waste management units as defined pursuant to RCRA or any comparable state
law; or (v) sites on or nominated for the National Priority List promulgated pursuant to CERCLA or
any state remedial priority list promulgated or published pursuant to any comparable state law;

          (e) there has been no Release or, to the Borrower’s knowledge, threatened Release, of
Hazardous Materials at, on, under or from the Borrower’s or any Restricted Subsidiary’s Properties,
there are no investigations, remediations, abatements, removals, or monitorings of Hazardous
Materials required under applicable Environmental Laws at such Properties and, to the knowledge of
the Borrower, none of such Properties are adversely affected by any Release or threatened Release
of a Hazardous Material originating or emanating from any other real property;

60

 

          (f) neither the Borrower nor any Restricted Subsidiary has received any written notice
asserting an alleged liability or obligation under any applicable Environmental Laws with respect
to the investigation, remediation, abatement, removal, or monitoring of any Hazardous Materials at,
under, or Released or threatened to be Released from any real properties offsite the Borrower’s or
any Restricted Subsidiary’s Properties and, to the Borrower’s knowledge, there are no conditions or
circumstances that would reasonably be expected to result in the receipt of such written notice;

          (g) there has been no exposure of any Person or property to any Hazardous Materials as a
result of or in connection with the operations and businesses of any of the Borrower’s or the
Restricted Subsidiaries’ Properties that would reasonably be expected to form the basis for a claim
for damages or compensation and, to the Borrower’s knowledge, there are no conditions or
circumstances that would reasonably be expected to result in the receipt of notice regarding such
exposure;

          (h) the Borrower and the Restricted Subsidiaries have provided to the Lenders complete and
correct copies of all environmental site assessment reports, investigations, studies, analyses, and
correspondence on environmental matters (including matters relating to any alleged non-compliance
with or liability under Environmental Laws) that are in any of the Borrower’s or the Restricted
Subsidiaries’ possession or control and relating to their respective Properties or operations
thereon.

     Section 7.07 Compliance with the Laws and Agreements; No Defaults.

          (a) Each of the Borrower and each Restricted Subsidiary is in compliance with all Governmental
Requirements applicable to it or its Property and all agreements and other instruments binding upon
it or its Property, and possesses all licenses, permits, franchises, exemptions, approvals and
other governmental authorizations necessary for the ownership of its Property and the conduct of
its business, except where the failure to do so, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

          (b) Neither the Borrower nor any Restricted Subsidiary is in default nor has any event or
circumstance occurred which, but for the expiration of any applicable grace period or the giving of
notice, or both, would constitute a default or would require the Borrower or a Restricted
Subsidiary to Redeem or make any offer to Redeem under any indenture, note, credit agreement or
instrument pursuant to which any Material Indebtedness is outstanding or by which the Borrower or
any Restricted Subsidiary or any of their Properties is bound.

          (c) No Default has occurred and is continuing.

     Section 7.08 Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” or a company “controlled” by
an “investment company,” within the meaning of, or subject to regulation under, the Investment
Company Act of 1940, as amended.

     Section 7.09 Taxes. Each of the Borrower and its Subsidiaries has timely filed or caused to be filed all Tax returns
and reports required to have been filed and has paid or caused to be paid all Taxes required to
have been paid by it, except (a) Taxes that are being contested in good faith by appropriate
proceedings and for which the Borrower or such Subsidiary, as

61

 

applicable, has set aside on its
books adequate reserves in accordance with GAAP or (b) to the extent that the failure to do so
could not reasonably be expected to result in a Material Adverse Effect. The charges, accruals and
reserves on the books of the Borrower and its Subsidiaries in respect of Taxes and other
governmental charges are, in the reasonable opinion of the Borrower, adequate.

     Section 7.10 ERISA.

          (a) The Borrower, the Subsidiaries and each ERISA Affiliate have complied in all material
respects with ERISA and, where applicable, the Code regarding each Plan.

          (b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where
applicable, the Code.

          (c) No act, omission or transaction has occurred which could result in imposition on the
Borrower, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) either a
civil penalty assessed pursuant to subsections (c), (i) or (l) of section 502 of ERISA or a tax
imposed pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary duty liability
damages under section 409 of ERISA.

          (d) No Plan (other than a defined contribution plan) or any trust created under any such Plan
has been terminated since September 2, 1974. No liability to the PBGC (other than for the payment
of current premiums which are not past due) by the Borrower, any Subsidiary or any ERISA Affiliate
has been or is expected by the Borrower, any Subsidiary or any ERISA Affiliate to be incurred with
respect to any Plan. No ERISA Event with respect to any Plan has occurred.

          (e) Full payment when due has been made of all amounts which the Borrower, the Subsidiaries or
any ERISA Affiliate is required under the terms of each Plan or applicable law to have paid as
contributions to such Plan as of the date hereof, and no accumulated funding deficiency (as defined
in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect to
any Plan.

          (f) The actuarial present value of the benefit liabilities under each Plan which is subject to
Title IV of ERISA does not, as of the end of the Borrower’s most recently ended fiscal year, exceed
the current value of the assets (computed on a plan termination basis in accordance with Title IV
of ERISA) of such Plan allocable to such benefit liabilities. The term “actuarial present value of
the benefit liabilities” shall have the meaning specified in section 4041 of ERISA.

          (g) Neither the Borrower, the Subsidiaries nor any ERISA Affiliate sponsors, maintains, or
contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including,
without limitation, any such plan maintained to provide benefits to former employees of such
entities, that may not be terminated by the Borrower, a Subsidiary or any ERISA Affiliate in its
sole discretion at any time without any material liability.

62

 

          (h) Neither the Borrower, the Subsidiaries nor any ERISA Affiliate sponsors, maintains or
contributes to, or has at any time in the six-year period preceding the date hereof sponsored,
maintained or contributed to, any Multiemployer Plan.

          (i) Neither the Borrower, the Subsidiaries nor any ERISA Affiliate is required to provide
security under section 401(a)(29) of the Code due to a Plan amendment that results in an increase
in current liability for the Plan.

     Section 7.11 Disclosure; No Material Misstatements. The Borrower has disclosed to the Administrative Agent and the Lenders all agreements,
instruments and corporate or other restrictions to which it or any of its Restricted Subsidiaries
is subject, and all other matters known to it, that, individually or in the aggregate, could
reasonably be expected to result in a Material Adverse Effect. None of the reports, financial
statements, certificates or other information furnished by or on behalf of the Borrower or any
Restricted Subsidiary to the Administrative Agent or any Lender or any of their Affiliates in
connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder
or under any other Loan Document (as modified or supplemented by other information so furnished)
contains any material misstatement of fact or omits to state any material fact necessary to make
the statements therein, in the light of the circumstances under which they were made, not
misleading; provided that, with respect to projected financial information, the Borrower
represents only that such information was prepared in good faith based upon assumptions believed to
be reasonable at the time. There is no fact peculiar to the Borrower or any Restricted Subsidiary
which could reasonably be expected to have a Material Adverse Effect or in the future is reasonably
likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the
Loan Documents or the other documents, certificates and statements furnished to the Administrative
Agent or the Lenders by or on behalf of the Borrower or any Restricted Subsidiary prior to, or on,
the date hereof in connection with the transactions contemplated hereby. There are no statements
or conclusions in any Reserve Report which are based upon or include misleading information or fail
to take into account material information regarding the matters reported therein, it being
understood that projections concerning volumes attributable to the Borrowing Base Properties and
related production and cost estimates contained in each Reserve Report are necessarily based upon
professional opinions, estimates and projections and that the Borrower and the Restricted
Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to
have been accurate.

     Section 7.12 Insurance. The Borrower has, and has caused all of its Restricted Subsidiaries to have, (a) all insurance
policies sufficient for the compliance by each of them with all material Governmental Requirements
and all material agreements and (b) insurance coverage in at least amounts and
against such risk (including, without limitation, public liability) that are usually insured
against by companies similarly situated and engaged in the same or a similar business for the
assets and operations of the Borrower and its Restricted Subsidiaries. The Administrative Agent
and the Lenders have been named as additional insureds in respect of such liability insurance
policies, and the Administrative Agent has been named as loss payee with respect to Property loss
insurance.

     Section 7.13 Restriction on Liens. Neither the Borrower nor any of the Restricted Subsidiaries is a party to any material agreement
or arrangement (other than (a) Capital Leases

63

 

creating Liens and Purchase Money Indebtedness
permitted by Section 9.03(c), but then only on the Property subject of such Capital Lease
or Purchase Money Indebtedness, (b) customary provisions restricting subletting or assignment of
leases or rights thereunder, (c) restrictions with respect to Property securing Indebtedness
permitted under Section 9.02 pursuant to Liens permitted under Section 9.03, and
(d) temporary restrictions with respect to an Asset Sale otherwise permitted hereunder pending the
consummation of such sale), or subject to any order, judgment, writ or decree, which either
restricts or purports to restrict its ability to grant Liens to the Administrative Agent and the
Lenders on or in respect of their Properties to secure the Secured Obligations and the Loan
Documents.

     Section 7.14 Subsidiaries. Except as set forth on Schedule 7.14 or as disclosed in writing to the Administrative
Agent (which shall promptly furnish a copy to the Lenders), which shall be a supplement to
Schedule 7.14, the Borrower has no Subsidiaries and the Borrower has no Foreign
Subsidiaries. Schedule 7.14 identifies each Subsidiary as either Restricted or
Unrestricted, and each Restricted Subsidiary on such schedule is a Wholly-Owned Subsidiary.

specified as the owner of the Borrowing Base Properties owns the net interests in Hydrocarbon
production attributable to the Borrowing Base Properties as reflected in the most recently
delivered Reserve Report, and the ownership of such Borrowing Base Properties shall not in any
material respect obligate the Borrower or such Restricted Subsidiary to bear the costs and expenses
relating to the maintenance, development and operations of each such Borrowing Base Property in an
amount in excess of the working interest of each Borrowing Base Property set forth in the most
recently delivered Reserve Report that is not offset by a

64

 

corresponding proportionate increase in
the Borrower’s or such Restricted Subsidiary’s net revenue interest in such Borrowing Base
Property.

          (c) All leases and agreements necessary for the conduct of the business of the Borrower and
the Restricted Subsidiaries are valid and subsisting, in full force and effect, and there exists no

Restricted Subsidiaries including, without limitation, all easements and rights of way, include all
rights and Properties necessary to permit the Borrower and the Subsidiaries to conduct their

reasonably be expected to result in a Material Adverse Effect. The Borrower and its Restricted
Subsidiaries either own or have valid licenses or other rights to use all databases, geological
data, geophysical data, engineering data, seismic data, maps, interpretations and other technical
information used in their businesses as presently conducted, subject to the limitations contained
in the agreements governing the use of the same, which limitations are customary for companies
engaged in the business of the exploration and production of Hydrocarbons, with such exceptions as
could not reasonably be expected to have a Material Adverse Effect.

          (a) Except for such acts or failures to act as could not be reasonably expected to have a
Material Adverse Effect, the Oil and Gas Properties (and Properties unitized therewith) of the
Borrower and its Restricted Subsidiaries have been maintained, operated and developed in a good and
workmanlike manner and in conformity with all Governmental Requirements and in conformity with the

for those as could not be reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas
Property (other than Royalty Interests) of the Borrower or any Restricted Subsidiary is subject to
having allowable production reduced below the full and regular allowable (including the maximum
permissible tolerance) because of any overproduction (whether or not the same was permissible at
the time) and (ii) none of the wells comprising a part of the Oil and Gas Properties (or Properties
unitized therewith) (other than Royalty Interests) of

65

 

the Borrower or any Restricted Subsidiary is
deviated from the vertical more than the maximum permitted by Governmental Requirements, and such
wells are, in fact, bottomed under and are producing from, and the well bores are wholly within,

          (b) Except for such acts or failures to act as could not be reasonably expected to have a
Material Adverse Effect, the offices, plants, wells, gas processing plants, platforms,
improvements, fixtures, equipment, and other Property (other than Oil and Gas Properties) owned,
leased or used by the Borrower and its Restricted Subsidiaries in the conduct of their businesses
are (i) structurally sound with no known defects, (ii) in good operating condition and repair,
subject to ordinary wear and tear, (iii) not in need of maintenance or repair except for ordinary,
routine maintenance and repair the cost of which is immaterial, (iv) sufficient for the operation
of the businesses of the Borrower and its Restricted Subsidiaries as currently conducted, and (v)
in conformity with all Governmental Requirements relating thereto.

Subsidiary at some future time without then or thereafter receiving full payment therefor exceeding
one-half bcf of gas (on an mcf equivalent basis) in the aggregate.

     Section 7.19 Marketing of Production. Except for contracts listed and in effect on the date hereof on Schedule 7.19, and
thereafter either disclosed in writing to the Administrative Agent or included in the most recently
delivered Reserve Report (with respect to all of which contracts the Borrower represents that it or
its Restricted Subsidiaries are receiving a price for all Hydrocarbon production attributable to
the Borrowing Base Properties sold thereunder which is computed substantially in accordance with
the terms of the relevant contract and are not having deliveries curtailed substantially below the
subject Property’s delivery capacity), no material agreements exist which are not cancelable on
sixty (60) days notice or less without penalty or detriment for the sale of Hydrocarbon production
attributable to the Borrowing Base Properties (including, without limitation, calls on or other
rights to purchase, production, whether or not the same are currently being exercised) that (a)
pertain to the sale of such production at a fixed price and (b) have a maturity or expiry date of
longer than six (6) months from the date hereof.

     Section 7.20 Security Instruments.

Agreement are effective to create, in favor of the Administrative Agent for the benefit of the
Secured Parties, a legal, valid and enforceable Lien on, and security interest in, all of the
Collateral, and (i) when financing statements and other filings in appropriate form are filed in
the offices specified in the Guaranty and Collateral Agreement and (ii) upon the taking of
possession or control by the Administrative Agent of the Collateral with respect to which a
security interest may be perfected only by possession or control (which possession or control shall
be given to the Administrative Agent to the extent possession or control by the Administrative

Collateral Agreement shall constitute fully perfected first priority Liens on, and security

Agent (or such other trustee as may be required or desired under local law) for the benefit of the
Secured Parties, legal, valid and enforceable Liens on, and security interests in, all of the
Mortgaged Property thereunder and the proceeds thereof, subject only to Excepted Liens, and when
the Mortgages are filed in the offices specified on Schedule 7.20 (or, in the case of any
Mortgage executed and delivered after the date thereof in accordance with the provisions of
Section 8.11 and Section 8.14, when such Mortgage is filed in the appropriate
offices), the Mortgages shall constitute fully perfected first priority Liens on, and security
interests in, all right, title and interest of the Loan Parties in the Mortgaged Property and the
proceeds thereof, in each case prior and superior in right to any other person, other than Liens
permitted by such Mortgage.

          (c) Valid Liens. Each Security Instrument delivered pursuant to Section 8.11
or Section 8.14, upon execution and delivery thereof, is effective to create in favor of
the Administrative Agent, for the benefit of the Secured Parties, legal, valid and enforceable
Liens on, and security interests in, all of the Collateral thereunder, and when all appropriate
filings or recordings are made in the appropriate offices as may be required under applicable
Governmental Requirements, such Security Instrument will constitute fully perfected first priority
Liens on, and security interests in, all right, title and interest of the Loan Parties in such
Collateral, in each case with no other Liens except for applicable Excepted Liens.

to refinance the Existing Credit Agreement and pay fees and expenses incurred therewith, (b) for
Capital Expenditures and Permitted Acquisitions, and (c) for general corporate purposes, including

engaged principally, or as one of its or their important activities, in the business of extending
credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin

     Section 8.08 Books and Records; Inspection Rights. The Borrower will, and will cause each Restricted Subsidiary to, keep proper books of record and
account in which full, true and correct entries are made of all dealings and transactions in
relation to its business and activities. The Borrower will, and will cause each Restricted
Subsidiary to, permit any representatives designated by the Administrative Agent or any Lender,
upon reasonable prior notice, to visit and inspect its Properties, to examine and make extracts
from its books and records, and to discuss its affairs, finances and condition with its officers
and independent accountants, all at such reasonable times and as often as reasonably requested.

     Section 8.09 Compliance with Laws. The Borrower will, and will cause each Restricted Subsidiary to, comply with all laws, rules,
regulations and orders of any Governmental Authority applicable to it or its Property, except where
the failure to do so, individually or in the aggregate, could not reasonably be expected to result
in a Material Adverse Effect.

     Section 8.10 Environmental Matters.

          (a) The Borrower shall at its sole expense: (i) comply, and shall cause its Properties and
operations and each Subsidiary and each Subsidiary’s Properties and operations to comply, with all
applicable Environmental Laws, the breach of which could be reasonably expected to have a Material
Adverse Effect; (ii) not dispose of or otherwise release, and shall cause each Subsidiary not to
dispose of or otherwise release, any Hazardous Material on, under, about or from any of the
Borrower’s or its Subsidiaries’ Properties or any other Property to the extent caused by the
Borrower’s or any of its Subsidiaries’ operations except in compliance with applicable
Environmental Laws, the disposal or release of which could reasonably be expected to have a
Material Adverse Effect; (iii) timely obtain or file, and shall cause each Subsidiary to timely
obtain or file, all notices, permits, licenses, exemptions, approvals, registrations or other
authorizations, if any, required under applicable Environmental Laws to be obtained or filed in
connection with the operation or use of the Borrower’s or its Subsidiaries’ Properties, which
failure to obtain or file could reasonably be expected to have a Material Adverse Effect; (iv)
promptly commence and diligently prosecute to completion, and shall cause each Subsidiary to

74

 

promptly commence and diligently prosecute to completion, any assessment, evaluation,
investigation, monitoring, containment, cleanup, removal, repair, restoration, remediation or other
remedial obligations (collectively, the “Remedial Work”) in the event any Remedial Work is
required or reasonably necessary under applicable Environmental Laws because of or in connection
with the actual or suspected past, present or future disposal or other actual or threatened release
of any Hazardous Material on, under, about or from any of the Borrower’s or its Subsidiaries’
Properties, which failure to commence and diligently prosecute to completion could reasonably be
expected to have a Material Adverse Effect; and (v) establish and implement, and shall cause each
Subsidiary to establish and implement, such procedures as may be necessary to continuously
determine and assure that the Borrower’s and its Subsidiaries’ obligations under this Section
8.10(a) are timely and fully satisfied, which failure to establish and implement could
reasonably be expected to have a Material Adverse Effect.

          (b) The Borrower will promptly, but in no event later than five (5) days of the occurrence of
a triggering event, notify the Administrative Agent and the Lenders in writing of any threatened
action, investigation or inquiry by any Governmental Authority or any threatened demand or lawsuit
by any landowner or other third party against the Borrower or its Subsidiaries or their Properties
of which the Borrower has knowledge in connection with any Environmental Laws (excluding routine
testing and corrective action) if the Borrower reasonably anticipates that such action will result
in liability (whether individually or in the aggregate) in excess of $10,000,000, not fully covered
by insurance, subject to normal deductibles.

          (c) The Borrower will, and will cause each Subsidiary to, provide environmental audits and
tests in accordance with American Society of Testing Materials standards upon request by the
Administrative Agent and the Lenders and no more than once per year in the absence of any Event of
Default (or as otherwise required to be obtained by the Administrative Agent or the Lenders by any
Governmental Authority), in connection with any future acquisitions of Oil and Gas Properties
(other than Royalty Interests).

     Section 8.11 Further Assurances.

          (a) The Borrower at its sole expense will, and will cause each Restricted Subsidiary to,
promptly execute and deliver to the Administrative Agent all such other documents, agreements and
instruments reasonably requested by the Administrative Agent to comply with, cure any defects or
accomplish the conditions precedent, covenants and agreements of the Borrower or any Restricted
Subsidiary, as the case may be, in the Loan Documents, including the Notes, or to further evidence
and more fully describe the Collateral intended as security for the Secured Obligations, or to
correct any material omissions in the Security Instruments, or to state more fully the obligations
secured therein, or to perfect, protect or preserve any Liens created pursuant to this Agreement or
any of the Security Instruments or the priority thereof, or to make any recordings, file any
notices or obtain any consents, all as may be reasonably necessary or appropriate, in the sole
discretion of the Administrative Agent, in connection therewith.

          (b) The Borrower hereby authorizes the Administrative Agent to file one or more financing or
continuation statements, and amendments thereto, relative to all or any part of the Collateral
without the signature of the Borrower or any other Guarantor where permitted by

75

 

law. A carbon,
photographic or other reproduction of the Security Instruments or any financing statement covering
such Collateral or any part thereof shall be sufficient as a financing statement where permitted by
law.

     Section 8.12 Reserve Reports.

          (a) On or before March 1st and September 1st of each year, commencing March 1, 2008, the
Borrower shall furnish to the Administrative Agent and the Lenders a Reserve Report evaluating the
Borrowing Base Properties of the Borrower and its Subsidiaries as of the immediately preceding
January 1st and July 1st. The Reserve Report as of January 1 of each year shall be prepared by one
or more Approved Petroleum Engineers, and the July 1 Reserve Report of each year shall be prepared
by or under the supervision of the chief engineer of the Borrower who shall certify such Reserve
Report to be true and accurate (provided, that projections concerning volumes attributable
to the Borrowing Base Properties and related production and cost estimates contained in such
Reserve Report are necessarily based upon professional opinions, estimates and projections and such
opinions, estimates and projections may not ultimately prove accurate) and to have been prepared in
accordance with the procedures used in the immediately preceding January 1 Reserve Report.

          (b) In the event of an Interim Redetermination, the Borrower shall furnish to the
Administrative Agent and the Lenders a Reserve Report prepared by or under the supervision of the
chief engineer of the Borrower who shall certify such Reserve Report to be true and accurate
(provided, that projections concerning volumes attributable to the Borrowing Base
Properties and related production and cost estimates contained in such Reserve Report are
necessarily based upon professional opinions, estimates and projections and such opinions,
estimates and projections may not ultimately prove accurate) and to have been prepared in
accordance with the procedures used in the immediately preceding January 1 Reserve Report. For any
Interim Redetermination requested by the Administrative Agent or the Borrower pursuant to
Section 2.08(b), the Borrower shall provide such Reserve Report with an “as of” date as
required by the Administrative Agent as soon as possible, but in any event no later than thirty
(30) days following the receipt of such request.

          (c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative
Agent and the Lenders a certificate from a Responsible Officer certifying that in all material
respects: (i) the information contained in the Reserve Report and any other information delivered
in connection therewith is true and correct (provided, that projections concerning volumes
attributable to the Borrowing Base Properties and related production and cost estimates contained
in such Reserve Report are necessarily based upon professional opinions, estimates and projections
and such opinions, estimates and projections may not ultimately prove accurate), (ii) the Borrower
or its Restricted Subsidiaries own good and defensible title to the Borrowing Base Properties and
such Properties are free of all Liens except for Liens permitted by Section 9.03, (iii)
except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances,
take or pay or other prepayments in excess of the volume specified in Section 7.18 with
respect to its Borrowing Base Properties which would require the Borrower or any Restricted
Subsidiary to deliver Hydrocarbons either generally or produced from such Borrowing Base Properties
at some future time without then or thereafter receiving full payment therefor, (iv) none of their
Borrowing Base Properties have been sold since the date

76

 

of the last Borrowing Base determination
except as set forth on an exhibit to the certificate, which certificate shall list all of its
Borrowing Base Properties sold and in such detail as
reasonably required by the Administrative Agent, (v) attached to the certificate is a list of
all marketing agreements entered into subsequent to the later of the date hereof or the most
recently delivered Reserve Report which the Borrower could reasonably be expected to have been
obligated to list on Schedule 7.19 had such agreement been in effect on the date hereof and
(vi) attached thereto is a schedule of the Borrowing Base Properties that are Mortgaged Properties
and demonstrating the percentage of the total value of the Borrowing Base Properties that the value
of such Mortgaged Properties represent in compliance with Section 8.14(a).

          (d) Concurrently with the delivery of the Reserve Reports in connection with Sections
8.12(a) and (b), the Borrower shall furnish to the Administrative Agent and the Lenders
a report setting forth, for the period since the last delivery of such information, the volume of
production and sales attributable to production (and the prices at which such sales were made and
the revenues derived from such sales ) during such period from the Oil and Gas Properties, and
setting forth the related ad valorem, severance and production taxes and lease operating expenses
attributable thereto and incurred during such period.

     Section 8.13 Title Information.

          (a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve
Report required by Section 8.12(a), the Borrower will deliver title information in form and
substance acceptable to the Administrative Agent covering enough of the Borrowing Base Properties
that were not included in the immediately preceding Reserve Report, so that the Administrative
Agent shall have received together with title information previously delivered to the
Administrative Agent, satisfactory title information on at least 80% of the total value of the
Borrowing Base Properties as set forth in such Reserve Report.

          (b) If the Borrower has provided title information for additional Properties under Section
8.13(a), the Borrower shall, within sixty (60) days of notice from the Administrative Agent
that title defects or exceptions exist with respect to such additional Properties, either (i) cure
any such title defects or exceptions (including defects or exceptions as to priority) which are not
permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged
Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens
described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii)
deliver title information in form and substance acceptable to the Administrative Agent so that the
Administrative Agent shall have received, together with title information previously delivered to
the Administrative Agent, satisfactory title information on at least 80% of the value of the
Borrowing Base Properties as set forth in the most recent Reserve Report.

          (c) If the Borrower is unable to cure any title defect requested by the Administrative Agent
or the Lenders to be cured within the 60-day period or the Borrower does not comply with the
requirements to provide acceptable title information covering 80% of the value of the Borrowing
Base Properties as set forth in the most recent Reserve Report, such default shall not be a
Default, but instead the Administrative Agent and/or the Majority Lenders shall have the right to
exercise the following remedy in their sole discretion from time to time,

77

 

and any failure to so exercise this remedy at any time shall not be a waiver as to future
exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the
Administrative Agent or the Majority Lenders are not satisfied with title to any Mortgaged Property
after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards
the 80% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders
that the then outstanding Borrowing Base shall be reduced by an amount as determined by the
Required Lenders to cause the Borrower to be in compliance with the requirement to provide
acceptable title information on 80% of the value of the Borrowing Base Properties as set forth in
the most recent Reserve Report. This new Borrowing Base shall become effective immediately after
receipt of such notice.

     Section 8.14 Additional Collateral; Additional Guarantors.

          (a) In connection with each Borrowing Base Redetermination, the Borrower shall review the
Reserve Report and the list of current Mortgaged Properties (as described in Section
8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 80% of the total
value of the Borrowing Base Properties as set forth in such Reserve Report after giving effect to
exploration and production activities, acquisitions, dispositions and production. In the event
that the Mortgaged Properties do not represent at least 80% of such total value, then the Borrower
shall, and shall cause its Restricted Subsidiaries to, grant, within thirty (30) days of delivery
of the certificate required under Section 8.12(c), to the Administrative Agent as security
for the Secured Obligations a first-priority Lien interest (provided that Excepted Liens of
the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject
to the provisos at the end of such definition) on additional Borrowing Base Properties not already
subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged
Properties will represent at least 80% of such total value. All such Liens will be created and
perfected by and in accordance with the provisions of deeds of trust, security agreements and
financing statements or other Security Instruments, all in form and substance reasonably
satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where
necessary or appropriate) counterparts for recording purposes. In order to comply with the
foregoing, if any Restricted Subsidiary places a Lien on its Oil and Gas Properties and such
Restricted Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with
Section 8.14(b).

          (b) In the event that (i) the Borrower or any Restricted Subsidiary acquires any Material
Domestic Subsidiary, (ii) the Borrower determines that any Restricted Subsidiary is a Material
Domestic Subsidiary or (iii) any Domestic Subsidiary incurs or guarantees any Indebtedness, the
Borrower shall promptly (and in any event within thirty (30) days of such acquisition,
determination, incurrence or guaranty) cause such Restricted Subsidiary to guarantee the Secured
Obligations pursuant to the Guaranty and Collateral Agreement. In connection with any guaranty,
the Borrower shall, or shall cause such Domestic Subsidiary to, (i) execute and deliver a
supplement to the Guaranty and Collateral Agreement executed by such Domestic Subsidiary, (ii)
cause the owner of the Equity Interests in such Domestic Subsidiary to pledge such Equity Interests
(including, without limitation, to the extent certificated, delivery of original stock certificates
evidencing the Equity Interests of such Domestic Subsidiary, together with an
appropriate undated stock powers for each certificate duly executed in blank by the registered

78

 

owner thereof) and (iii) execute and deliver such other additional closing documents, certificates
and legal opinions as shall reasonably be requested by the Administrative Agent.

          (c) In the event that the Borrower or any Domestic Subsidiary becomes the owner of a Foreign
Subsidiary, then the Borrower shall promptly, or shall cause such Domestic Subsidiary to promptly
(and in any event within thirty (30) days after such acquisition or formation) (i) execute and
deliver a supplement to the Guaranty and Collateral Agreement, (ii) pledge 66% of all the Equity
Interests of such Foreign Subsidiary (including, without limitation, to the extent certificated,
delivery of original stock certificates evidencing such Equity Interests of such Foreign
Subsidiary, together with appropriate stock powers for each certificate duly executed in blank by
the registered owner thereof), so long as such pledge does not result in adverse tax consequences
to the Borrower or such Domestic Subsidiary, and (iii) execute and deliver such other additional
closing documents, certificates and legal opinions as shall reasonably be requested by the
Administrative Agent.

          (d) The Borrower will at all times cause the other material tangible and intangible Property
of the Borrower and each Restricted Subsidiary not covered by clauses (a) through (c) above (other
than the Royalty Interests) to be subject to a Lien pursuant to the Security Instruments;
provided, that in the case of a Permitted Acquisition, the Borrower and the applicable
Restricted Subsidiaries shall have thirty (30) days (subject to extension in the sole discretion of
the Administrative Agent) in which to satisfy this Section 8.14(d); provided
further, that if the Administrative Agent determines, in its sole discretion, that the cost
of obtaining a Lien on any such other material tangible or intangible Property is excessive in
relation to the value afforded thereby, the Administrative Agent may waive the requirements of this
Section 8.14(d) with respect to such Property.

     Section 8.15 ERISA Compliance. The Borrower will promptly furnish and will cause the Subsidiaries and any ERISA Affiliate to
promptly furnish to the Administrative Agent (i) promptly after the filing thereof with the United
States Secretary of Labor, the Internal Revenue Service or the PBGC, copies of each annual and
other report with respect to each Plan or any trust created thereunder, (ii) immediately upon
becoming aware of the occurrence of any ERISA Event or of any “prohibited transaction,” as
described in section 406 of ERISA or in section 4975 of the Code, in connection with any Plan or
any trust created thereunder, a written notice signed by the President or the principal Financial
Officer, the Subsidiary or the ERISA Affiliate, as the case may be, specifying the nature thereof,
what action the Borrower, the Subsidiary or the ERISA Affiliate is taking or proposes to take with
respect thereto, and, when known, any action taken or proposed by the Internal Revenue Service, the
Department of Labor or the PBGC with respect thereto, and (iii) immediately upon receipt thereof,
copies of any notice of the PBGC’s intention to terminate or to have a trustee appointed to
administer any Plan. With respect to each Plan (other than a Multiemployer Plan), the Borrower
will, and will cause each Subsidiary and ERISA Affiliate to, (i) satisfy in full and in a timely
manner, without incurring any late payment or underpayment charge or penalty and without giving
rise to any lien, all of the contribution and funding requirements of section 412 of the Code
(determined without regard to subsections (d), (e), (f) and (k) thereof) and of section 302 of
ERISA (determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay,
or cause to be paid, to the PBGC in a timely manner, without incurring any late payment or
underpayment charge or penalty, all premiums required pursuant to sections 4006 and 4007 of ERISA.

79

 

     Section 8.16 Unrestricted Subsidiaries. The Borrower:

          (a) will cause the management, business and affairs of each of the Borrower and its Restricted
Subsidiaries to be conducted in such a manner (including, without limitation, by keeping separate
books of account, furnishing separate financial statements of Unrestricted Subsidiaries to
creditors and potential creditors thereof and by not permitting Properties of the Borrower and its
Restricted Subsidiaries to be commingled) so that each Unrestricted Subsidiary that is a
corporation will be treated as a corporate entity separate and distinct from Borrower and the
Restricted Subsidiaries;

          (b) will not, and will not permit any of the Restricted Subsidiaries to, incur, assume,
guarantee or be or become liable for any Indebtedness of any of the Unrestricted Subsidiaries; and

          (c) will not permit any Unrestricted Subsidiary to hold any Equity Interest in, or any
Indebtedness of, the Borrower or any Restricted Subsidiary.

ARTICLE IX

Negative Covenants

     Until the Commitments have expired or terminated and the principal of and interest on each
Loan and all fees payable hereunder and all other amounts payable under the Loan Documents have
been paid in full and all Letters of Credit have expired or terminated and all LC Disbursements
shall have been reimbursed, the Borrower (on behalf of itself and its Subsidiaries) and each
Guarantor by its execution of the Guaranty and Collateral Agreement covenants and agrees with the
Lenders, the Administrative Agent and the Issuing Banks that:

     Section 9.01 Financial Covenants.

          (a) Interest Coverage Ratio. The Borrower will not, as of the last day of any fiscal
quarter, permit the ratio of Consolidated EBITDA for the period of four (4) fiscal quarters then
ending to Consolidated Interest Expense for such period to be less than 2.50 to 1.00.

          (b) Total Leverage Ratio.

               (i) If the Borrower has no Indebtedness of the type described in Section 9.02(h), the
Borrower will not, at any time, permit the Total Leverage Ratio to be greater
than 5.00 to 1.00; provided that during a Specified Acquisition Period, the Total
Leverage Ratio shall not exceed 5.25 to 1.00.

               (ii) If the Borrower has Indebtedness of the type described in Section 9.02(h), the
Borrower will not, at any time, permit the Total Leverage Ratio to be greater than 5.25 to 1.00;
provided that during a Specified Acquisition Period, the Total Leverage Ratio shall not
exceed 5.75 to 1.00.

80

 

          (c) Senior Secured Leverage Ratio. If the Borrower has Indebtedness of the type
described in Section 9.02(h), then the Borrower will not permit the Senior Secured Leverage
Ratio to exceed 4.25 to 1.00; provided that during a Specified Acquisition Period, the
Senior Secured Leverage Ratio shall not exceed 4.75 to 1.00.

          (d) Certain Calculations. With respect to any period during which a Permitted
Acquisition has occurred (a “Subject Transaction”), for purposes of determining compliance
with the financial covenants set forth in this Section 9.01, Adjusted Consolidated EBITDA
shall be calculated with respect to such period on a pro forma basis (including pro forma
adjustments arising out of events which are directly attributable to a specific transaction, are
factually supportable and are expected to have a continuing impact, in each case, determined on a
basis consistent with Article 11 of Regulation S-X promulgated under the Securities Act of 1933 and
as interpreted by the staff of the SEC, which would include cost savings resulting from head count
reduction, closure of facilities and similar restructuring charges, which pro forma adjustments
shall be certified by the chief financial officer of the General Partner) using the historical
audited financial statements of any business so acquired or to be acquired and the consolidated
financial statements of the Borrower and its Subsidiaries which shall be reformulated as if such
Subject Transaction, and any Indebtedness incurred or repaid in connection therewith, had been
consummated or incurred or repaid at the beginning of such period (and assuming that such
Indebtedness bears interest during any portion of the applicable measurement period prior to the
relevant acquisition at the weighted average of the interest rates applicable to outstanding Loans
incurred during such period).

          (e) Material Projects.

               (i) With respect to any Material Project, the following adjustments (the “Material Project
EBITDA Adjustments”) may be made, at the Borrower’s discretion, to Adjusted Consolidated
EBITDA:

          (A) prior to the Commercial Operation Date of such Material Project (but
including the fiscal quarter in which such Commercial Operation Date occurs), a
percentage (based on the then-current completion percentage of such Material Project
as of the date of determination) of an amount to be approved by the Administrative
Agent as the projected Adjusted Consolidated EBITDA attributable to such Material
Project for the first 12-month period following the scheduled Commercial Operation
Date of such Material Project (such amount to be determined based upon projected
revenues from customer contracts, projected revenues that are determined by the
Administrative Agent, in its discretion, to otherwise be highly probable, the
creditworthiness and applicable
projected production of the prospective customers, capital and other costs,
operating and administrative expenses, scheduled Commercial Operation Date,
commodity price assumptions and other factors deemed appropriate by the
Administrative Agent), may be added, at the Borrower’s option, to actual Adjusted
Consolidated EBITDA for the fiscal quarter in which construction or expansion of
such Material Project commences and for each fiscal quarter thereafter until the
Commercial Operation Date of such Material Project (including the fiscal quarter in
which such Commercial Operation Date occurs,

81

 

but net of any actual Adjusted
Consolidated EBITDA attributable to such Material Project following such Commercial
Operation Date); provided that if the actual Commercial Operation Date does
not occur by the scheduled Commercial Operation Date, then the foregoing amount
shall be reduced for quarters ending after the scheduled Commercial Operation Date
to (but excluding) the first full quarter after the actual Commercial Operation
Date, by the following percentage amounts depending on the period of delay (based on
the period of actual delay or then-estimated delay, whichever is longer): (i) 90
days or less, 0%, (ii) longer than 90 days, but not more than 180 days, 50%, and
(iii) longer than 180 days, 100%; and

          (B) beginning with the first full fiscal quarter following the Commercial
Operation Date of such Material Project and for the two (2) immediately succeeding
fiscal quarters, an amount equal to the projected Adjusted Consolidated EBITDA
attributable to such Material Project for the balance of the four (4) full fiscal
quarter period following such Commercial Operation Date, may be added, at the
Borrower’s option, to actual Adjusted Consolidated EBITDA for such fiscal quarters.

     (ii) Notwithstanding anything else contained in this Section 9.01(e),:

          (A) no Material Project EBITDA Adjustment shall be allowed with respect to any
Material Project unless at least thirty (30) days prior to the last day of the
fiscal quarter for which the Borrower desires to commence inclusion of such Material
Project EBITDA Adjustment in Adjusted Consolidated EBITDA with respect to a Material
Project (the “Initial Quarter”), the Borrower shall have delivered to the
Administrative Agent written pro forma projections of Adjusted Consolidated EBITDA
attributable to such Material Project and such other documentation as the
Administrative Agent may reasonably request, all in form and substance satisfactory
to the Administrative Agent,

          (B) no Material Project EBITDA Adjustment shall be allowed with respect to any
Material Project unless prior to the last day of the Initial Quarter, the
Administrative Agent shall have approved (such approval not to be unreasonably
withheld) such projections and shall have received such other information and
documentation as the Administrative Agent may reasonably request, all in form and
substance satisfactory to the Administrative Agent,

          (C) the aggregate amount of all Material Project EBITDA Adjustments with
respect to a particular Material Project shall not exceed twenty percent (20%) of
the capital cost of such Material Project, and

          (D) the aggregate amount of all Material Project EBITDA Adjustments during any
period shall be limited to fifteen percent (15%) of the total actual Adjusted
Consolidated EBITDA for such period (which total actual Adjusted Consolidated EBITDA
shall be determined without including any Material Project EBITDA Adjustments).

82

 

     Section 9.02 Indebtedness. The Borrower will not, and will not permit any Restricted Subsidiary to, incur, create, assume
or suffer to exist any Indebtedness, except:

          (a) the Secured Obligations arising under the Loan Documents or any guaranty of or suretyship
arrangement for the Secured Obligations arising under the Loan Documents;

          (b) Indebtedness of the Borrower and its Restricted Subsidiaries existing on the date hereof
that is set forth on Schedule 9.02, and any Permitted Refinancing Indebtedness in respect

deferred purchase price of Property or services, from time to time incurred in the ordinary course
of business which are not greater than ninety (90) days past the date of invoice or delinquent or
which are being contested in good faith by appropriate action and for which adequate reserves have
been maintained in accordance with GAAP;

          (d) Indebtedness (i) under Capital Leases and (ii) that constitutes Purchase Money
Indebtedness; provided that the aggregate amount of all Indebtedness described in this
Section 9.02(d) at any one time outstanding shall not exceed an amount equal to two and
half percent (2.5%) of Consolidated Tangible Net Worth;

          (e) Indebtedness associated with bonds or surety obligations required by Governmental
Requirements in connection with the operation of the Oil and Gas Properties;

          (f) unsecured intercompany Indebtedness between the Borrower and any Restricted Subsidiary or
between Restricted Subsidiaries to the extent permitted by Section 9.05(g);
provided that such Indebtedness is not held, assigned, transferred, negotiated or pledged
to any Person other than the Borrower or one of its Wholly-Owned Subsidiaries, and,
provided further, that any such Indebtedness owed by a Loan Party shall be
subordinated to the Secured Obligations on terms set forth in the Guaranty and Collateral
Agreement;

          (g) endorsements of negotiable instruments for collection in the ordinary course of business;

          (h) unsecured Indebtedness in respect of a private placement or public sale of unsecured
senior or subordinated notes by the Borrower and unsecured guarantees of such notes by one or more
of the Guarantors; provided that (i) no Event of Default has occurred and is continuing or
would occur after giving effect to such incurrence, (ii) after giving effect to the incurrence of
such Indebtedness on a pro forma basis, the Borrower shall be in compliance with all covenants set
forth in Section 9.01, (iii) the latest maturity date of such Indebtedness shall not be
prior to the ninety-first (91st) day after the Maturity Date and shall not have a
weighted average life to maturity that is shorter than that of the existing Loans, and (iv) such
Indebtedness does not have the benefit of, directly or indirectly, any covenants or definitions
that are more restrictive than those set forth herein; provided further that upon
the incurrence of such Indebtedness, the Borrowing Base will be redetermined using the procedures
for an Interim Redetermination in accordance with Section 2.08

83

 

          (i) Indebtedness arising from agreements providing for indemnification or from guaranties or
letters of credit, surety bonds or performance bonds securing the performance of (but not the
payment of the purchase price by) the Borrower or any Restricted Subsidiary pursuant to such
agreements, in connection with Permitted Acquisitions or Asset Sales by the Borrower or any of its
Restricted Subsidiaries;

          (j) Indebtedness which may be deemed to exist pursuant to any guaranty, performance, surety,
statutory, appeal or similar obligations (but not obligations for borrowed money) incurred in the
ordinary course of business;

          (k) Indebtedness under Treasury Management Agreements not to exceed $5,000,000 in the

Loans then outstanding, together with accrued interest thereon and all fees and the other
obligations of the Borrower and the Guarantors accrued hereunder and under the other Loan Documents
(including, without limitation, the payment of cash collateral to secure the LC Exposure as
provided in Section 2.09(j)), shall automatically become due and payable, without
presentment, demand, protest or other notice of any kind, all of which are hereby waived by the
Borrower and each Guarantor.

ARTICLE XI

The Agents

          (a) Appointment; Powers. Each of the Lenders and each Issuing Bank hereby irrevocably appoints
the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions
on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms
hereof and the other Loan Documents, together with such actions and powers as are reasonably
incidental thereto.

     Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall have no
duties or obligations except those expressly set forth in the Loan Documents. Without limiting the
generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or
other implied duties, regardless of whether a Default has occurred and is continuing (the use of
the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent
is not intended to connote any fiduciary or other implied (or express) obligations arising under
agency doctrine of any applicable law; rather, 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 Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except as provided in Section
11.03, and (c) except as expressly set forth herein, the Administrative Agent shall have no
duty to disclose, and shall not be liable for the failure to disclose, any information relating to
the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as
Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be
deemed not to have knowledge of any Default unless and until written notice thereof is given to the
Administrative Agent by the Borrower or a Lender, and shall not be responsible for or have any duty
to ascertain or inquire

97

 

into (i) any statement, warranty or representation made in or in connection
with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or
other document delivered hereunder or under any other Loan Document or in connection herewith or
therewith, (iii) the performance or observance of any of the covenants, agreements or other terms
or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability,
effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement,
instrument or document, (v) the satisfaction of any condition set forth in ARTICLE VI or
elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the
Administrative Agent or as to those
conditions precedent expressly required to be to the Administrative Agent’s satisfaction, (vi) the
existence, value, perfection or priority of any collateral security or the financial or other
condition of the Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any
failure by the Borrower or any other Person (other than itself) to perform any of its obligations
hereunder or under any other Loan Document or the performance or observance of any covenants,
agreements or other terms or conditions set forth herein or therein. For purposes of determining
compliance with the conditions specified in ARTICLE VI, each Lender shall be deemed to have
consented to, approved or accepted or to be satisfied with, each document or other matter required
thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the
Administrative Agent shall have received written notice from such Lender prior to the proposed
closing date specifying its objection thereto.

     Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no duty to take any
discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is
required to exercise in writing as directed by the Majority Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as provided in Section
12.02) and in all cases the Administrative Agent shall be fully justified in failing or
refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written
instructions from the Majority Lenders or the Lenders, as applicable, (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section
12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the
Lenders against any and all liability and expenses which may be incurred by it by reason of taking
or continuing to take any such action. The instructions as aforesaid and any action taken or
failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders.
If a Default has occurred and is continuing, then the Administrative Agent shall take such action
with respect to such Default as shall be directed by the requisite Lenders in the written
instructions (with indemnities) described in this Section 11.03, provided that,
unless and until the Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from taking such action,
with respect to such Default as it shall deem advisable in the best interests of the Lenders. In
no event, however, shall the Administrative Agent be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this Agreement, the Loan
Documents or applicable law. If a Default has occurred and is continuing, neither the Syndication
Agent nor any Co-Documentation Agent shall have any obligation to perform any act in respect
thereof. The Administrative Agent shall not be liable for any action taken or not taken by it with
the consent or at the request of the Majority Lenders or the Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as

98

 

provided in Section
12.02), and otherwise the Administrative Agent shall not be liable for any action taken or not
taken by it hereunder or under any other Loan Document or under any other document or instrument
referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS
OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct.

     Section 11.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon,
and shall not incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine and to have been
signed or sent by the proper Person. The Administrative Agent also may rely upon any statement
made to it orally or by telephone and believed by it to be made by the proper Person, and shall not
incur any liability for relying thereon and each of the Borrower, the Lenders and the Issuing Banks
hereby waives the right to dispute the Administrative Agent’s record of such statement, except in
the case of gross negligence or willful misconduct by the Administrative Agent. The Administrative
Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants
and other experts selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts. The Administrative
Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless
and until a written notice of the assignment or transfer thereof permitted hereunder shall have
been filed with the Administrative Agent.

     Section 11.05 Subagents. The Administrative Agent may perform any and all its duties and exercise its
rights and powers by or through any one or more sub-agents appointed by the Administrative Agent.
The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its
rights and powers through their respective Related Parties. The exculpatory provisions of the
preceding Sections of this ARTICLE XI shall apply to any such sub-agent and to the Related
Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided for herein as well
as activities as Administrative Agent.

     Section 11.06 Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance
of a successor Administrative Agent as provided in this Section 11.06, the Administrative
Agent may resign at any time by notifying the Lenders, the Issuing Banks and the Borrower, and the
Administrative Agent may be removed at any time with or without cause by the Majority Lenders.
Upon any such resignation or removal, the Majority Lenders shall have the right, in consultation
with the Borrower, to appoint a successor. If no successor shall have been so appointed by the
Majority Lenders and shall have accepted such appointment within thirty (30) days after the
retiring Administrative Agent gives notice of its resignation or removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders and the
Issuing Banks, appoint a successor Administrative Agent which shall be a bank with an office in New
York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as
Administrative Agent hereunder by a successor, such successor shall succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The
fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable
to its predecessor unless

99

 

otherwise agreed between the Borrower and such successor. After the
Administrative Agent’s resignation hereunder, the provisions of this ARTICLE XI and
Section 12.03 shall continue in effect for the benefit of such retiring Administrative
Agent, its sub-agents and their respective Related Parties in respect of any actions taken or
omitted to be taken by any of them while it was acting as Administrative Agent.

     Section 11.07 Agents as Lenders. Each bank serving as an Agent hereunder shall have the same rights and
powers in its capacity as a Lender as any other Lender and may exercise the same as though it were
not an Agent, and such bank and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if it were not an Agent hereunder.

     Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon
the Administrative Agent, any other Agent, any Issuing Bank or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit analysis and decision
to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also
acknowledges that it will, independently and without reliance upon the Administrative Agent, any
other Agent, any Issuing Bank or any other Lender and based on such documents and information as it
shall from time to time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any other Loan Document, any related agreement or
any document furnished hereunder or thereunder. The Agents shall not be required to keep
themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries
of this Agreement, the Loan Documents or any other document referred to or provided for herein or
to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices,
reports and other documents and information expressly required to be furnished to the Lenders by
the Administrative Agent hereunder, neither the Agents nor the Arrangers shall have any duty or
responsibility to provide any Lender with any credit or other information concerning the affairs,
financial condition or business of the Borrower (or any of its Affiliates) which may come into the
possession of such Agent or Arranger or any of its Affiliates. In this regard, each Lender
acknowledges that Vinson & Elkins L.L.P. is acting in this transaction as special counsel to the
Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or
any Loan Document. Each other party hereto will consult with its own legal counsel to the extent
that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

     Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the
Administrative Agent (irrespective of whether the principal of any Loan shall then be due and
payable as herein expressed or by declaration or otherwise and irrespective of whether the
Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered,
by intervention in such proceeding or otherwise:

          (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans and all other Secured Obligations that are owing and unpaid and to
file such other documents as may be necessary or advisable in order to have the

100

 

claims of the
Lenders and the Administrative Agent (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Lenders and the Administrative Agent and their
respective agents and counsel and all other amounts due the Lenders and the Administrative Agent
under Section 12.03) allowed in such judicial proceeding; and

          (b) to collect and receive any monies or other property payable or deliverable on any such
claims and to distribute the same; and

any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in
any such judicial proceeding is hereby authorized by each Lender to make such payments to the
Administrative Agent and, in the event that the Administrative Agent shall consent to the making of
such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the
reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its
agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement,
adjustment or composition affecting the Secured Obligations or the rights of any Lender or to
authorize the Administrative Agent to vote in respect of the claim of any Lender in any such
proceeding.

     Section 11.10 Authority of Administrative Agent to Release Collateral and Liens. Each Lender and each
Issuing Bank hereby authorizes the Administrative Agent to release any Collateral that is permitted
to be sold or released pursuant to the terms of the Loan Documents. Each Lender and each Issuing
Bank hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the
Borrower’s sole cost and expense, any and all releases of Liens, termination statements,
assignments or other documents reasonably requested by the Borrower in connection with any sale or
other disposition of Property to the extent such sale or other disposition is permitted by the
terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents.

     Section 11.11 The Arrangers, the Syndication Agent and the Co-Documentation Agents. The Arrangers, the
Syndication Agent and the Co-Documentation Agents shall have no duties, responsibilities or
liabilities under this Agreement and the other Loan Documents other than their duties,
responsibilities and liabilities in their capacity as Lenders hereunder.

          (a) No failure on the part of the Administrative Agent, any Issuing Bank or any Lender to
exercise and no delay in exercising, and no course of dealing with respect to, any
right, power or privilege, or any abandonment or discontinuance of steps to enforce such
right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor
shall any single or partial exercise of any right, power or privilege under any of the Loan
Documents preclude any other or further exercise thereof or the exercise of any other right, power
or privilege. The rights and remedies of the Administrative Agent, the Issuing Banks and the
Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any
rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or
any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by Section 12.02(b), and then such waiver or
consent shall be effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of
Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative
Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Default at the time.

          (b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any
provision thereof may be waived, amended or modified except pursuant to an agreement or agreements
in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the
Administrative Agent with the consent of the Majority Lenders; provided that no such
agreement shall (i) increase the Commitment of any Lender without the written consent of such
Lender, (ii) increase the Borrowing Base without the written consent (or deemed consent pursuant to
Section 2.08(c)(iii)) of each Lender, decrease or maintain the Borrowing Base without the
consent (or deemed consent pursuant to Section 2.08(c)(iii)) of the Required Lenders, or
modify in any manner Section 2.08 without the consent of each Lender, (iii) reduce the
principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce
any fees payable hereunder, or reduce any other Secured Obligations hereunder or under any other
Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the
scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or
any interest thereon, or any fees payable hereunder, or any other Secured Obligations hereunder or
under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or
postpone or extend the Termination Date without the written consent of each Lender affected
thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter
the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi)
waive or amend Section 8.14 or change the definition of the terms “Domestic Subsidiary”,
“Foreign Subsidiary”, “Material Domestic Subsidiary” or “Subsidiary”, without the written consent
of each Lender, (vii) release any Guarantor (except as set forth in the Guaranty and Collateral
Agreement), release all or substantially all of the Collateral (other than as provided in

rights or duties of the Administrative Agent, any Issuing Bank or the Swingline Lender hereunder or
under any other Loan Document without the prior written consent of the Administrative Agent, such
Issuing Bank or the Swingline Lender as the case may be.
Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be
effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked
as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the
Lenders.

          (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the

WARRANTY OR COVENANT OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY
INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR LETTER
OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, (A) ANY REFUSAL BY

RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND
REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH
INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER,
WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION,
ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF
TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT
ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY
INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED
EXPENSES (i) ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE

BREACH IN BAD FAITH OF SUCH INDEMNITEE’S OBLIGATIONS UNDER THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT OR (ii) ARISE SOLELY BY REASON OF CLAIMS BETWEEN THE ADMINISTRATIVE AGENT AND LENDERS OR
BY THEIR SHAREHOLDERS AGAINST SUCH PERSONS.

          (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the
Agents, the Arrangers, any Issuing Bank or the Swingline Lender under Section 12.03(a) or
(b), but without affecting such payment obligations of the Borrower, each Lender severally
agrees to pay to such Agents, Arranger, Issuing Bank, Swingline Lender, as the case may be, such
Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense
or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed
expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was
incurred by or asserted against such Agent, Arranger, Issuing Bank or Swingline Lender in its
capacity as such.

          (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby
waives, any claim against any Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the
use of the proceeds thereof.

          (e) All amounts due under this Section 12.03 shall be payable upon written demand
therefor.

     Section 12.04 Assignments and Participations.

          (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the

106

 

Borrower may
not assign or otherwise transfer any of its rights or obligations hereunder without the prior
written consent of each Lender (and any attempted assignment or transfer by the Borrower without
such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights
or obligations hereunder except in accordance with this Section 12.04. Nothing in this
Agreement, expressed or implied, shall be construed to confer upon any Person (other than the
parties hereto, their respective successors and assigns permitted hereby (including any Affiliate
of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in
Section 12.04(c)) and, to the extent expressly contemplated hereby, the
Related Parties of each of the Administrative Agent, the Issuing Banks and the Lenders) any
legal or equitable right, remedy or claim under or by reason of this Agreement.

          (b) (i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may
assign to one or more assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans at the time owing to it) with the prior
written consent (such consent not to be unreasonably withheld or delayed) of:

          (A) the Borrower, provided that no consent of the Borrower shall be
required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund
or, if an Event of Default has occurred and is continuing, any other assignee; and

          (B) the Administrative Agent, provided that no consent of the
Administrative Agent shall be required for an assignment to an assignee that is a
Lender immediately prior to giving effect to such assignment.

               (ii) Assignments shall be subject to the following additional conditions:

          (A) except in the case of an assignment to a Lender or an Affiliate of a Lender
or an assignment of the entire remaining amount of the assigning Lender’s
Commitment, the amount of the Commitment 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) shall not be
less than $5,000,000 unless each of the Borrower and the Administrative Agent
otherwise consent, provided that no such consent of the Borrower shall be
required if an Event of Default has occurred and is continuing;

          (B) 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;

          (C) the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Assumption, together with a processing and
recordation fee of $3,500; and

          (D) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire.

107

 

               (iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from
and after the effective date specified in each Assignment and Assumption the assignee thereunder
shall be a party hereto and, to the extent of the interest assigned by such Assignment and
Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption,
be released from its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender’s rights and
obligations under this Agreement, such Lender shall cease to be a party hereto but shall
continue to be entitled to the benefits of Section 5.01, Section 5.02, Section
5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this Section 12.04 shall be
treated for purposes of this Agreement as a sale by such Lender of a participation in such rights
and obligations in accordance with Section 12.04(c).

               (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, 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 Commitment of, and
principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms
hereof from time to time (the “Register”). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent, the Issuing Banks 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 Borrower, any Issuing Bank and any Lender, at any
reasonable time and from time to time upon reasonable prior notice.

               (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning
Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee
shall already be a Lender hereunder), the processing and recordation fee referred to in Section
12.04(b)(ii)(C) and any written consent to such assignment required by Section
12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the
information contained therein in the Register. No assignment shall be effective for purposes of
this Agreement unless it has been recorded in the Register as provided in this Section
12.04(b).

          (c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or any
Issuing Bank, sell participations to one or more banks or other entities (a “Participant”)
in all or a portion of such Lender’s rights and obligations under this Agreement (including all or
a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s
obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations and (C) the
Borrower, the Administrative Agent, the Issuing Banks 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 described in the proviso to Section
12.02 that affects such Participant. In addition, such

108

 

agreement must provide that the
Participant be bound by the provisions of Section 12.03. Subject to Section
12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of
Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it
were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To
the extent permitted by law, each Participant also shall be entitled to the benefits of Section
12.08 as though it were a Lender, provided that such Participant agrees to be subject
to Section 4.01(c) as though it were a Lender.

     (ii) A Participant shall not be entitled to receive any greater payment under
Section 5.01 or Section 5.03 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 Borrower’s 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 5.03 unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 5.03(e) as though it were a Lender.

          (d) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including, without
limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank, and this
Section 12.04(d) shall not apply to any such pledge or assignment of a security interest;
provided that no such pledge or assignment of a security interest shall release a Lender
from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as
a party hereto.

          (e) Notwithstanding any other provisions of this Section 12.04, no transfer or
assignment of the interests or obligations of any Lender or any grant of participations therein
shall be permitted if such transfer, assignment or grant would require the Borrower and the
Guarantors to file a registration statement with the SEC or to qualify the Loans under the “Blue
Sky” laws of any state.

     Section 12.05 Survival; Revival; Reinstatement.

          (a) All covenants, agreements, representations and warranties made by the Borrower herein and
in the certificates or other instruments delivered in connection with or pursuant to this Agreement
or any other Loan Document shall be considered to have been relied upon by the other parties hereto
and shall survive the execution and delivery of this Agreement and the making of any Loans and
issuance of any Letters of Credit, regardless of any investigation made by any such other party or
on its behalf and notwithstanding that the Administrative Agent, any Issuing Bank or any Lender may
have had notice or knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as long as the principal
of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement
is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments
have not expired or terminated. The provisions of Section 5.01, Section 5.02,
Section 5.03 and Section 12.03 and ARTICLE XI shall survive and remain in
full force and effect regardless of the consummation of the transactions contemplated hereby, the
repayment of the Loans, the expiration or termination

109

 

of the Letters of Credit and the Commitments
or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

          (b) To the extent that any payments on the Secured Obligations or proceeds of any Collateral
are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to
be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law,
common law or equitable cause, then to such extent, the Secured Obligations so satisfied shall be
revived and continue as if such payment or proceeds had not been received and
the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and
remedies under this Agreement and each Loan Document shall continue in full force and effect. In
such event, each Loan Document shall be automatically reinstated and the Borrower shall take such
action as may be reasonably requested by the Administrative Agent and the Lenders to effect such
reinstatement.

     Section 12.06 Counterparts; Integration; Effectiveness.

          (a) This Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of which when taken
together shall constitute a single contract.

          (b) This Agreement, the other Loan Documents and any separate letter agreements with respect
to fees payable to the Administrative Agent constitute the entire contract among the parties
relating to the subject matter hereof and thereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof and thereof. THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND
MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

          (c) Except as provided in Section 6.01, this Agreement shall become effective when it
shall have been executed by the Administrative Agent and when the Administrative Agent shall have
received counterparts hereof which, when taken together, bear the signatures of each of the other
parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart of a signature
page of this Agreement by facsimile or other electronic transmission shall be effective as delivery
of a manually executed counterpart of this Agreement.

     Section 12.07 Severability. Any provision of this Agreement or any other Loan Document held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability without affecting the
validity, legality and enforceability of the remaining provisions hereof or thereof; and the
invalidity of a particular provision in a particular jurisdiction shall not invalidate such
provision in any other jurisdiction.

     Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender
and each of its Affiliates is hereby authorized at any time and from time

110

 

to time, to the fullest
extent permitted by law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations (of whatsoever kind,
including, without limitations obligations under Hedging Agreements) at any time owing by such
Lender or Affiliate to or for the credit or the account of the Borrower or any Restricted
Subsidiary against any of and all the obligations of the Borrower or any Restricted Subsidiary owed
to such Lender now or hereafter existing under this Agreement or any other Loan Document,
irrespective of whether or not such Lender shall have made any demand under this Agreement or any
other Loan Document and although such obligations may be unmatured. The
rights of each Lender under this Section 12.08 are in addition to other rights and remedies
(including other rights of setoff) which such Lender or its Affiliates may have.

     Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

          (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL
LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE
ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE
COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW
YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND

JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF
FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR
PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND
DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE
HAVING JURISDICTION.

          (c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED
COURTS IN ANY ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED
MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER
ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH
SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE
RIGHT OF A PARTY OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR
TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION.

111

 

          (d) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM

ACTUAL DAMAGES;
(iii) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OF COUNSEL FOR ANY PARTY

INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY
AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS
SECTION 12.09.

     Section 12.10 Headings. Article and Section headings and the Table of Contents used herein are for
convenience of reference only, are not part of this Agreement and shall not affect the construction
of, or be taken into consideration in interpreting, this Agreement.

     Section 12.11 Confidentiality. Each of the Administrative Agent, the Issuing Banks and the Lenders agrees
to maintain the confidentiality of the Information (as defined below), except that Information may
be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including
accountants, legal counsel and other advisors (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such Information and instructed
to keep such Information confidential), (b) to the extent requested by any regulatory authority,
(c) to the extent required by applicable laws or regulations or by any subpoena or similar legal
process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection
with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or
proceeding relating to this Agreement or any other Loan Document or the enforcement of rights
hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same
as those of this Section 12.11, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations under this Agreement or
(ii) any actual or prospective counterparty (or its advisors) to any Hedging Agreement relating to
the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of this Section
12.11 or (ii) becomes available to the Administrative Agent, any Issuing Bank or any Lender on
a nonconfidential basis from a source other than the Borrower. For the purposes of this
Section 12.11, “Information” means all information received from the Borrower or
any Restricted Subsidiary relating to the Borrower or any Restricted Subsidiary and their
businesses, other than any such information that is available to the Administrative Agent, any
Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Borrower or a
Restricted Subsidiary; provided that, in the case of information received from the Borrower
or any Restricted Subsidiary after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section 12.11 shall be considered to have complied with its
obligation to do

112

 

so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own confidential
information.

     Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall
conform strictly to usury laws applicable to it. Accordingly, if the Transactions contemplated
hereby would be usurious as to any Lender under laws applicable to it (including the laws of the
United States of America or any other jurisdiction whose laws may be mandatorily applicable to such
Lender notwithstanding the other provisions of this Agreement), then, in that event,
notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into
in connection with or as security for the Secured Obligations, it is agreed as follows: (i) the
aggregate of all consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by such Lender under any of the Loan
Documents or agreements or otherwise in connection with the Loans shall under no circumstances
exceed the maximum amount allowed by such applicable law, and any excess shall be canceled
automatically and if theretofore paid shall be credited by such Lender on the principal amount of
the Secured Obligations (or, to the extent that the principal amount of the Secured Obligations
shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and
(ii) in the event that the maturity of the Loans is accelerated by reason of an election of the
holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the
event of any required or permitted prepayment, then such consideration that constitutes interest
under law applicable to any Lender may never include more than the maximum amount allowed by such
applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be
canceled automatically by such Lender as of the date of such acceleration or prepayment and, if
theretofore paid, shall be credited by such Lender on the principal amount of the Secured
Obligations (or, to the extent that the principal amount of the Secured Obligations shall have been
or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or
agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall,
to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and
spread throughout the stated term of the Loans until payment in full so that the rate or amount of
interest on account of any Loans hereunder does not exceed the maximum amount allowed by such
applicable law. If at any time and from time to time (i) the amount of interest payable to any
Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant
to this Section 12.12 and (ii) in respect of any subsequent interest computation period the
amount of interest otherwise payable to such Lender would be less than the amount of interest
payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the
amount of interest payable to such Lender in respect of such subsequent interest computation period
shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total
amount of interest payable to such Lender shall equal the total amount of interest which would have

Plan), the aggregate number of shares of Stock that may be sold pursuant to Options granted under
the Plan shall be 5,000,000 shares of Stock, provided, that, effective as of January 1, 2004, and
as of each subsequent January 1 during the Plan Term (as defined in Section 16), the aggregate

     Grant of Options.

          Option Grants. The Company shall grant Options under the Plan to all Eligible
Employees until the earlier of: (i) the date on which the number of shares of Stock available

Employee who is an Eligible Employee on the Enrollment Date of an Offering Period, and on the first
Trading Day of such Offering Period, shall be granted an Option with respect to such Offering
Period on the Date of Grant, and such Eligible Employee shall, to the extent such Eligible Employee
elects to participate in the Plan in accordance with Section 3(b), be a Participant. Each Option
with respect to an Offering Period shall expire on the last Date of Exercise occurring during that
Offering Period with respect to which such Option was granted, unless such Option terminates
earlier in accordance with Section 6, 7, 10 or 12 (pursuant to Section 10(b)(i) the last Date of
Exercise for any Option that is outstanding on December 1, 2005, shall be the last Trading Day
prior to December 31, 2005, and all Offering Periods that are ongoing as of December 1, 2005, shall
terminate on December 31, 2005). Subject to Section 5, the number of shares of Stock subject to an
Option held by a Participant that may be purchased on any Date of Exercise shall equal the balance
then in the Participant’s Account (or portion thereof to be applied to the exercise of such
Option), determined as of such Date of Exercise, divided by the Option Price of such Option;
provided, however, that, on any Date of Exercise, a Participant

3

 

may not purchase an aggregate of more than 5,000 shares of Stock under the Option or Options
granted to and held by such Participant on such Date of Exercise; and, provided, further, that the
number of shares of Stock for which an Option shall become exercisable on any Date of Exercise
shall not exceed the number determined in accordance with subsection (c). The Company shall not
grant an Option with respect to an Offering Period to any Participant who is not an Eligible
Employee on the Enrollment Date of such Offering Period, and the first Trading Day of such Offering
Period.

          Election to Participate; Payroll Deduction Authorization.

          An Eligible Employee who is granted an Option shall become a Participant in the Plan only by
means of authorizing payroll deductions. Each such Eligible Employee who elects to participate in
the Plan with respect to an Offering Period shall, not later than the Enrollment Date of the
Offering Period, deliver to the Company a completed written payroll deduction authorization in a
form prepared by the Committee; provided, however, that, for the first Offering Period under the
Plan, such written payroll authorization shall be delivered or transmitted to the Company no later
than July 10, 2003 (or such later date as the Committee shall designate prior to the grant of such
Options). An Eligible Employee’s written payroll deduction authorization is referred to herein as
the “Authorization.” Each Participant’s Authorization shall give notice of such Participant’s
election to participate in the Plan for the Offering Period (and subsequent Offering Periods) and
shall designate a whole percentage of such Participant’s Compensation to be withheld by the Company
or the Designated Subsidiary Corporation employing such Participant on each Payday during the
Offering Period (and subsequent Offering Periods); provided, however, that, for the first Offering
Period under the Plan, each Participant’s Authorization shall designate a whole percentage of such
Participant’s Compensation to be withheld on the Payday occurring on July 18, 2003 (or the first
Payday occurring on or after the Date of Grant of the first Offering Period) and each Payday
thereafter. A Participant may designate any whole percentage of Compensation which is not less
than one percent (1%) and not more than twenty percent (20%).

          A Participant’s Compensation payable during an Offering Period shall be withheld each Payday
through payroll deduction in an amount equal to the percentage specified in the Authorization, and
such amount shall be credited to such Participant’s Account under the Plan. A Participant may
increase or decrease the percentage of Compensation designated in the Authorization, subject to the
limits of this subsection (b), or may suspend the Authorization, provided, that any such change or
suspension must be made no later than five (5) business days before the end of a payroll period for
such change or suspension to apply with respect to the Payday for such payroll period.

          An Eligible Employee who is granted an Option prior to January 1, 2006, and who does not elect
to participate in the Plan by delivering to the Company an Authorization not later than the date
prescribed in paragraph (i) may subsequently become a Participant in such Offering Period effective
as of the first Trading Day following any Date of Exercise during such Offering Period by
delivering an Authorization to the Company prior to such Trading Day.

          Any Authorization shall remain in effect for each subsequent Offering Period, unless the
Participant submits a new Authorization pursuant to this subsection (b), withdraws from the Plan
pursuant to Section 6, or terminates employment as provided in Section 7. Notwithstanding the
foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code or Sections 3(a),
(c) or (d) of the Plan, the Company may reduce a Participant’s rate of payroll deductions to zero
at such time during any Offering Period. Payroll deductions shall recommence at the rate provided
by the Participant in his or her Authorization to the extent such payroll deductions may be applied
to purchase shares of Stock in accordance with Section 423(b)(8) of the Code and Sections 3(a), (c)
and (d) of the Plan, unless such Participant submits a new Authorization pursuant to this
subsection (b), withdraws from the Plan pursuant to Section 6, or terminates employment as provided
in Section 7 of the Plan.

          $25,000 Limitation.

          No Eligible Employee shall be granted an Option under the Plan which permits his or her rights
to purchase shares of Stock under the Plan, together with other Options or options to purchase
shares of Stock or other stock under all other employee stock purchase plans of the Company, any
Parent Corporation or any Subsidiary Corporation subject to the Section 423 of the Code, to accrue
at a rate which exceeds $25,000 of fair market value of such shares of Stock or other stock
(determined at the time the Option or other option is granted) for each calendar year in which the
Option or other option is outstanding. For purpose of the limitation imposed by this subsection
(c), (A) the right to purchase shares of Stock or other stock under an Option or other option
accrues when the Option or other option (or any portion thereof) first becomes exercisable during
the calendar year, (B) the right to purchase shares of

4

 

Stock or other stock under an Option or other option accrues at the rate provided in the
Option or other option, but in no case may such rate exceed $25,000 of the fair market value of
such Stock or other stock (determined at the time such Option or other option is granted) for any
one calendar year, and (C) a right to purchase Stock or other stock which has accrued under an
Option or other option may not be carried over to any other Option or other option. The limitation
under this subsection (c) shall be applied in accordance with Section 423(b)(8) of the Code and the
Treasury Regulations thereunder.

          For purposes of paragraph (i) (and subject to paragraph (iii)), for a Date of Exercise, (A) a
Participant’s Option (if such Participant then holds only one Option), or, (B) if a Participant has
been granted and then holds more than one Option, the Option designated by such Participant (or
deemed to have been designated by such Participant) to be exercised on a Date of Exercise, shall
become exercisable on such Date of Exercise only to the extent permitted by the limitation under
paragraph (i).

          For purposes of paragraph (i), for a Date of Exercise, if a Participant has been granted and
holds more than one Option, and has designated more than one Option to be exercised on a Date of
Exercise in accordance with Section 5(b)(i), then with respect to such Date of Exercise, the
Options designated by such Participant shall become exercisable only to the extent permitted under
paragraph (i), determined as follows:

          The limitation under paragraph (i) first shall be applied to the Option
designated by such Participant that has the least Option Price. If more than one
outstanding Option so designated by such Participant has the least Option Price,
then the limitation under paragraph (i) first shall be applied to the Option
designated by such Participant that had the least Fair Market Value of a share of
Stock on its Date of Grant. If more than one such outstanding Option so designated
by such Participant has the least Fair Market Value of a share of Stock on its Date
of Grant, then the $25,000 limitation under paragraph (i) first shall be applied to
the Option that has the earliest Date of Grant.

          The limitation under paragraph (i) shall be applied to the other Options
designated to be exercised by such Participant on such Date of Exercise in
sequential order in accordance with subparagraph (A).

          Each Option so designated by such Participant shall become exercisable in
accordance with subparagraphs (A) and (B) on such Date of Exercise only to the
extent of the least of the following: (1) the number of shares determined under
limitation under paragraph (i) and taking into account other Options that have
already become exercisable on such Date of Exercise, (2) the limits set forth in
Section 3(a) and taking into account other Options that have already become
exercisable on such Date of Exercise, and (3) the number of shares of Stock
purchasable under such Option based on the percentage of the balance then credited
to the Participant’s Account designated by the Participant with respect to such
Option in accordance with Section 5(b)(ii).

          For purposes of paragraph (i), the rights to purchase shares of Stock under the
outstanding Options granted to and held by such Participant which are not designated
to be exercised by such Participant on such Date of Exercise shall not become
exercisable on such Date of Exercise.

          Five Percent Holders. No Employee will be granted an Option under the Plan if
immediately after the grant, such Employee (or any other person whose stock would be attributed to
such Employee pursuant to Section 424(d) of the Code) would own shares of Stock or other stock
and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or of any Subsidiary
Corporation or Parent Corporation.

        Exercise of Options; Option Price.

          Option Exercise. Subject to Sections 3 and 5, each Participant’s Option or Options
shall become exercisable, on each Date of Exercise occurring during the Offering Period of such
Option to the extent that the balance then in the Participant’s Account is sufficient to purchase,
at the Option Price, shares of the Stock subject to the Option and, on such Date of Exercise, such
Participant, automatically and without any act on such Participant’s part, shall be deemed to have
exercised such Option on such Date of Exercise to the extent of the balance of the

5

 

Account to be so applied, provided, however, that any balance that is insufficient to purchase
a full share of Stock shall be carried over and remain credited to such Participant’s Account; and,
provided, further, that any additional balance in such Participant’s Account shall not be carried
over and shall be promptly refunded to such Participant without interest thereon.

          Option Price Defined. The option price per share of Stock (the “Option Price”) to be
paid by a Participant upon the exercise of the Participant’s Option on a Date of Exercise shall be
equal to 85% of the lesser of: (i) the Fair Market Value of a share of Stock on such Date of
Exercise, and (ii) the Fair Market Value of a share of Stock on the Date of Grant for such Option;
provided, however, that in no event may the Option Price be less than par value of a share of
Stock. The Fair Market Value of a share of Stock as of a given date shall be: (A) the closing
price of a share of Stock on the principal exchange on which the Stock is then trading, if any, on
such date (or, if shares of Stock were not traded on such date, then on the next preceding trading
day during which a sale occurred); (B) if the Stock is not traded on an exchange, but is quoted on
Nasdaq or a successor quotation system, (I) the last sales price (if the Stock is then listed as a
National Market Issue under the NASD National Market System), or (II) the mean between the closing
representative bid and asked prices (in all other cases) for a share of Stock on such date (or, if
shares of Stock were not traded on such date, then on the next preceding trading day during which a
sale occurred) as reported by Nasdaq or such successor quotation system; (III) if the Stock is not
publicly traded on an exchange and not quoted on Nasdaq or a successor quotation system, the mean
between the closing bid and asked prices for a share of Stock on such date (or, if shares of Stock
were not traded on such date, then on the next preceding trading day during which a sale occurred),
as determined in good faith by the Committee; or (IV) if the Stock is not publicly traded, the fair
market value of a share of Stock established by the Committee acting in good faith.

          Book Entry/Share Certificates. As soon as practicable after the purchase of shares of
Stock upon the exercise of an Option by a Participant, the Company shall issue the shares of Stock
to such Participant and such shares shall be held in the custody of the Company, or if applicable,
the Agent, for the benefit of the Participant. The Company or the Agent shall make an entry on its
books and records indicating that the shares of Stock purchased in connection with such exercise
(including any partial share) have been duly issued as of that date to such Participant. A
Participant shall have the right at any time to request in writing a certificate or certificates
for all or a portion of the whole shares of Stock purchased hereunder. Upon receipt of a
Participant’s written request for any such certificate, the Company shall (or shall cause the Agent
to), within ten (10) days after the date of such receipt, deliver any such certificate to the
Participant; provided, however, that Committee, in its sole discretion, may place restrictions on
the issuance of certificates with respect to Stock purchased hereunder in accordance with
applicable law. Nothing in this subsection (c) shall prohibit the sale or other disposition by a
Participant of shares of Stock purchased hereunder. In the event the Company is required to obtain
authority from any commission or agency to issue any certificate or certificates for all or a
portion of the whole shares of Stock purchased hereunder, the Company shall seek to obtain such
authority as soon as reasonably practicable.

          Pro Rata Allocations. If the total number of shares of Stock for which Options are to
be exercised on any date exceeds the number of shares of Stock remaining unsold under the Plan
(after deduction for all shares of Stock for which Options have theretofore been exercised), the
Committee shall make a pro rata allocation of the available remaining shares of Stock in as nearly
a uniform manner as shall be practicable and the balance of the amount credited to the Account of
each Participant which has not been applied to the purchase of shares of Stock shall be paid to
such Employee in one lump sum in cash within thirty (30) days after the Date of Exercise, without
any interest thereon.

          Information Statement. The Company shall provide each Participant whose Option is
exercised with an information statement in accordance with Section 6039(a) of the Code and the
Treasury Regulations thereunder. The Company shall maintain a procedure for identifying
certificates of shares of Stock sold upon the exercise of Options in accordance with Section
6039(b) of the Code.

     Multiple Options.

          An Eligible Employee shall be granted an Option for an Offering Period in accordance with
Section 3(a), irrespective of whether such Eligible Employee was granted one or more Options for
prior Offering Periods, and, accordingly, an Eligible Employee may hold Options with respect to
more than one Offering Period.

6

 

          Subject to Section 3, if a Participant has been granted and holds Options with respect to more
than one Offering Period as of a Date of Exercise, such Option or Options shall be exercisable on
such Date of Exercise as follows:

          Such Participant may designate in writing one or more of the outstanding Options to be
exercised on the Date of Exercise, on a form prepared by the Committee. Such written designation
must be made and delivered to the Company not later than five (5) days prior to such Date of
Exercise. The outstanding Options not designated by the Participant will not become exercisable
and will not be exercised on such Date of Exercise. A separate written designation shall be
required for each Date of Exercise on which a Participant has more than one outstanding Option.

          If such Participant designates more than one Option to be exercised in accordance with
paragraph (i), the written designation also shall include the percentage of the balance then
credited to such Participant’s Account to be applied to each Option to be so exercised on the Date
of Exercise. The Participant may designate 10% increments (or any multiple thereof) of the balance
in such Participant’s Account to be applied to each Option to be so exercised, and totaling 100% of
the balance credited to the Participant’s Account for the Options to be exercised. On the Date of
Exercise, to the extent each Option designated by the Participant becomes exercisable, the
Participant shall automatically exercise each such Option, in accordance with percentage designated
by the Participant of the balance then credited to the Participant’s Account in accordance with
Section 4(a) and subject to the limitations of Section 3(c)(iii).

          If such Participant fails to make a timely written designation in accordance with paragraph
(i) with respect to a Date of Exercise, such Participant shall be deemed to have designated the
outstanding Option with the least Option Price (as determined under Section 4(b)) for such Date of
Exercise to be exercised, and to have applied 100% of the balance then credited to the
Participant’s Account in accordance with Section 4(a) of such Option and subject to the limitations
of Section 3(c)(ii). For purposes of the foregoing sentence, if more than one outstanding Option
held by such Participant has the least Option Price, then the Participant shall be deemed to have
designated the outstanding Option with the earliest Date of Grant to be exercised.

     Withdrawal from the Plan.

          Withdrawal Election. A Participant may withdraw from participation under the Plan at
any time, except that a Participant may not withdraw from an Offering Period on or after the
Trading Day next preceding the last Date of Exercise of such Offering Period. Subject to the
foregoing, a Participant electing to withdraw from the Plan must deliver to the Company a notice of
withdrawal in a form prepared by the Committee (the “Withdrawal Election”), not later than the last
Trading Day preceding a Date of Exercise for such Offering Period. Upon receipt of a Participant’s
Withdrawal Election, the Company or Subsidiary Corporation employing the Participant shall pay to
the Participant the amount credited to the Participant’s Account in one lump sum payment in cash,
without any interest thereon, and subject to Section 4(c), the Company shall (or shall cause the
Agent to) deliver to the Participant certificates for any whole shares of Stock previously
purchased by the Participant, in either case within thirty (30) days of receipt of the
Participant’s Withdrawal Election. Upon receipt of a Participant’s Withdrawal Election by the
Company, the Participant shall cease to participate in the Plan and the Participant’s Option for
such Offering Period shall terminate.

          Eligibility following Withdrawal. A Participant who withdraws from the Plan preceding
a Date of Exercise with respect to an Offering Period and who is still an Eligible Employee may
elect to participate in any subsequent Offering Period by delivering to the Company an
Authorization pursuant to Section 3(b).

     Termination of Employment. If the employment of a Participant with the Company or a
Designated Subsidiary Corporation terminates for any reason, the Participant’s participation in the
Plan automatically and without any act on the Participant’s part shall terminate as of the date of
the termination of the Participant’s employment. As soon as practicable after such a termination
of employment, the Company or Designated Subsidiary Corporation employing the Participant shall pay
to the Participant (or, in the event of the Participant’s death, the legal representative of the
Participant’s estate) the amount credited to the Participant’s Account in one lump sum payment in
cash, without any interest thereon, and subject to Section 4(c), the Company shall (or shall cause
the Agent to) deliver to the Participant (or, in the event of the Participant’s death, the legal
representative of the Participant’s estate) certificates for any whole shares of Stock previously
purchased by the Participant. Upon a Participant’s termination of employment covered by this
Section, the Participant’s Authorization and Options under the Plan shall terminate.

7

 

     Restriction upon Assignment. An Option granted under the Plan shall not be
transferable and is exercisable during the Participant’s lifetime only by the Participant. An
Option granted under the Plan shall not be exercisable after the death of the Participant. The
Company shall not recognize and shall be under no duty to recognize any assignment or alienation of
the Participant’s interest in the Plan, the Participant’s Option or any rights under the
Participant’s Option.

     No Rights of Stockholders until Shares Issued. With respect to shares of Stock
subject to an Option, a Participant shall not be deemed to be a stockholder of the Company, and the
Participant shall not have any of the rights or privileges of a stockholder, until such shares have
been issued to the Participant following exercise of the Participant’s Option. No adjustments
shall be made for dividends (ordinary or extraordinary, whether in cash securities, or other
property) or distribution or other rights for which the record date occurs prior to the date of
such issuance, except as otherwise expressly provided herein.

     Changes in the Stock and Corporate Events; Adjustment of Options.

          Subject to Section 10(c), in the event that the Committee, in its sole discretion, determines
that any dividend or other distribution (whether in the form of cash, Stock, other securities, or
other property), recapitalization, reclassification, stock split, reverse stock split,
reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, liquidation,
dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the
assets of the Company, or exchange of Stock or other securities of the Company, issuance of
warrants or other rights to purchase Stock or other securities of the Company, or other similar
corporate transaction or event, affects the Stock such that an adjustment is appropriate in order
to prevent dilution or enlargement of the benefits or potential benefits intended to be made
available under the Plan or with respect to an Option, then the Committee shall, in such manner as
it may deem equitable, proportionately adjust any or all of:

          the number and kind of shares of Stock (or other securities or property) with respect to which
Options may be granted (including, but not limited to, adjustments of the limitation in Section
3(a) on the maximum number of shares of Stock which may be purchased),

          the number and kind of shares of Stock (or other securities or property) subject to
outstanding Options, and

          the exercise price with respect to any Option.

          Subject to Section 10(c), in the event of any transaction or event described in Section 10(a)
or any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the
Company, or the financial statements of the Company or any affiliate, or of changes in applicable
laws, regulations, or accounting principles, the Committee, in its sole discretion, and on such
terms and conditions as it deems appropriate, either by the terms of the Option or by action taken
prior to the occurrence of such transaction or event and either automatically or upon the
Participant’s request, is hereby authorized to take any one or more of the following actions
whenever the Committee determines that such action is appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available under the Plan or
with respect to any Option under the Plan, to facilitate such transactions or events or to give
effect to such changes in laws, regulations or principles:

          To provide that all Options outstanding shall terminate without being exercised on such date
as the Committee determines in its sole discretion;

          To provide that all Options outstanding shall be exercised prior to the Date of Exercise of
such Options on such date as the Committee determines in its sole discretion and such Options shall
terminate immediately after such exercises.

          To provide for either the purchase of any Option outstanding for an amount of cash equal to
the amount that could have been obtained upon the exercise of such Option had such Option been
currently exercisable, or the replacement of such Option with other rights or property selected by
the Committee in its sole discretion;

          To provide that such Option be assumed by the successor or survivor corporation, or a parent
or subsidiary thereof, or shall be substituted for by similar options, covering the stock of the
successor or survivor

8

 

corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number
and kind of shares and prices; and

          To make adjustments in the number and type of shares of Stock (or other securities or
property) subject to outstanding Options, or in the terms and conditions of outstanding Options, or
Options which may be granted in the future.

          No adjustment or action described in this Section 10 or in any other provision of the Plan
shall be authorized to the extent that such adjustment or action would cause the Plan to fail to
satisfy the requirements of Section 423 of the Code. Furthermore, no such adjustment or action
shall be authorized to the extent such adjustment or action would result in short-swing profits
liability under Section 16 of the Exchange Act, or violate the exemptive conditions of Rule 16b-3
unless the Committee determines that the Option is not to comply with such exemptive conditions.
The number of shares of Common Stock subject to any Option shall always be rounded to the next
whole number.

          The existence of the Plan and the Options granted hereunder shall not affect or restrict in
any way the right or power of the Company or the stockholders of the Company to make or authorize
any adjustment, recapitalization, reorganization or other change in the Company’s capital structure
or its business, any merger or consolidation of the Company, any issue of stock or of options,
warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks
whose rights are superior to or affect the Stock or the rights thereof of which are convertible
into or exchangeable for Stock, or the dissolution or liquidation of the Company, or any sale or
transfer of all or any part of its assets or business, or any other corporate act or proceeding,
whether of a similar character or otherwise.

     Use of Funds; No Interest Paid. All funds received or held by the Company under the
Plan shall be included in the general funds of the Company free of any trust or other restriction
and may be used for any corporate purpose. No interest will be paid to any Participant or credited
to any Participant’s Account with respect to such funds.

     Amendment, Suspension or Termination of the Plan. The Board or the Committee may
amend, suspend, or terminate the Plan at any time and from time to time, provided, however, that
only the Board may amend the Plan: (a) to increase the number of shares of Stock that may be sold
pursuant to Options under the Plan, as provided in Section 2, (b) to change the corporations or
class of corporations whose employees will be offered Options under the Plan, or (c) in any manner
that would cause the Plan to no longer be an “employee stock purchase plan,” within the meaning of
Section 423(b) of the Code. No such amendment, suspension or termination shall adversely affect
the rights of any Participant in any Option previously granted; provided, however, that the Board
or the Committee may amend Section 2 at any time and from time to time to decrease the number of
shares of Stock that may be sold pursuant to Options under the Plan; provided, further, that the
Board or the Committee may at any time and from time to time terminate all outstanding Options, or
the outstanding Options with respect to one or more Offering Period or amend all outstanding
Options, or the outstanding Options with respect to one or more Offering Periods, to suspend
payroll deductions otherwise to be applied to the exercise of such Options. In the event all of a
Participant’s outstanding Options are terminated, the balance then in such Participant’s Account
shall be refunded to such Participant without interest thereon. To the extent necessary to comply
with Rule 16b-3 under the Exchange Act, or under Section 423 of the Code (or any successor rule or
provision or any applicable law or regulation), the Company will obtain stockholder approval for
any amendment in such a manner and to such a degree as so required.

     Administration by Committee; Rules and Regulations.

          Appointment of Committee. The Plan shall be administered by the Committee, which
shall be composed of not less than two members of the Board, each of whom shall be a “non-employee
director” within the meaning of Rule 16b-3 which has been adopted by the Securities and Exchange
Commission under the Exchange Act. Each member of the Committee shall serve for a term commencing
on a date specified by the Board and continuing until the member dies, resigns or is removed from
office by the Board. The Committee at its option may utilize the services of an agent to assist in
the administration of the Plan, including establishing and maintaining an individual securities
account under the Plan for each Participant.

          Duties and Powers of Committee. It shall be the duty of the Committee to conduct the
general administration of the Plan in accordance with the provisions of the Plan. The Committee
shall have the power to

9

 

interpret the Plan and the terms of the Options and to adopt such rules for the
administration, interpretation, and application of the Plan as are consistent therewith and to
interpret, amend or revoke any such rules. In its absolute discretion, the Board may at any time
and from time to time exercise any and all rights and duties of the Committee under the Plan.

          Majority Rule. The Committee shall act by a majority of its members in office. The
Committee may act either by vote at a meeting or by a memorandum or other written instrument signed
by a majority of the Committee.

          Compensation; Professional Assistance; Good Faith Actions. All expenses and
liabilities incurred by members of the Committee in connection with the administration of the Plan
shall be borne by the Company. The Committee may, with the approval of the Board, employ
attorneys, consultants, accountants, appraisers, brokers or other persons. The Committee, the
Company and its officers and directors shall be entitled to rely upon the advice, opinions or
valuations of any such persons. All actions taken and all interpretations and determinations made
by the Committee in good faith shall be final and binding upon all Participants, the Company and
all other interested persons. No member of the Committee shall be personally liable for any
action, determination or interpretation made in good faith with respect to the Plan or the Options,
and all members of the Committee shall be fully protected by the Company in respect to any such
action, determination, or interpretation.

          Delegation of Authority. The Committee at its option may delegate its authority
hereunder to a committee of one or more officers of the Company, except to the extent necessary to
comply with the requirements of Rule 16b-3 of the Exchange Act. Any delegation hereunder shall be
subject to the restrictions and limits that the Committee specifies at the time of such delegation
of authority and may be rescinded at any time by the Committee. At all times, any committee
appointed under this Section 13(e) shall serve in such capacity at the pleasure of the Committee.

     Designation of Subsidiary Corporations. The Board shall designate from among the
Subsidiary Corporations, as determined from time to time, the Subsidiary Corporation or Subsidiary
Corporations whose Employees shall be eligible to be granted Options under the Plan. The Board may
designate a Designated Subsidiary Corporation, or terminate the designation of a Subsidiary
Corporation, without the approval of the stockholders of the Company.

     No Rights as an Employee. Nothing in the Plan shall be construed to give any person
(including any Participant) the right to remain in the employ of the Company, a Parent Corporation
or a Subsidiary Corporation or to affect the right of the Company, any Parent Corporation or any
Subsidiary Corporation to terminate the employment of any person (including any Participant) at any
time, with or without cause.

     Plan Term; Approval by Stockholders. Subject to approval by the stockholders of the
Company in accordance with this Section, the Plan shall be in effect from the Effective Date until
June 30, 2013 (the “Plan Term”), unless sooner terminated in accordance with Section 12. No Option
may be granted during any period of suspension of the Plan or after termination of the Plan. The
Plan shall be submitted for the approval of the Company’s stockholders within twelve (12) months
after the date of the adoption of the Plan by the Board. Options may be granted prior to such
stockholder approval; provided, however, that such Options shall not be exercisable prior to the
time when the Plan is approved by the Company’s stockholders; and, provided, further, that if such
approval has not been obtained by the end of said 12-month period, all Options previously granted
under the Plan shall thereupon terminate without being exercised.

     Effect upon Other Plans. The adoption of the Plan shall not affect any other
compensation or incentive plans in effect for the Company, any Parent Corporation or any Subsidiary
Corporation. Nothing in this Plan shall be construed to limit the right of the Company, any Parent
Corporation or any Subsidiary Corporation to: (a) establish any other forms of incentives or
compensation for employees of the Company, any Parent Corporation or any Subsidiary Corporation or
(b) grant or assume options otherwise than under the Plan in connection with any proper corporate
purpose, including, but not by way of limitation, the grant or assumption of options in connection
with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business,
stock or assets of any corporation, firm or association.

     Conditions to Issuance of Stock Certificates. The Company shall not be required to
issue or deliver any certificate or certificates for shares of Stock purchased upon the exercise of
Options prior to fulfillment of all the following conditions:

          The admission of such shares to listing on all stock exchanges, if any, on which is then
listed; and

          The completion of any registration or other qualification of such shares under any state or
federal law or under the rulings or regulations of the Securities and Exchange Commission or any
other governmental regulatory body, which the Committee shall, in its absolute discretion, deem
necessary or advisable; and

          The obtaining of any approval or other clearance from any state or federal governmental agency
which the Committee shall, in its absolute discretion, determine to be necessary or advisable; and

          The payment to the Company of all amounts which it is required to withhold under federal,
state or local law upon exercise of the Option; and

          The lapse of such reasonable period of time following the exercise of the Option as the
Committee may from time to time establish for reasons of administrative convenience.

     Notification of Disposition. Each Participant shall give prompt notice to the Company
of any disposition or other transfer of any shares of Stock purchased upon exercise of an Option if
such disposition or transfer is made: (a) within two (2) years from the Date of Grant of the
Option, or (b) within one (1) year after the transfer of such shares of Stock to such Participant
upon exercise of such Option. Such notice shall specify the date of such disposition or other
transfer and the amount realized, in cash, other property, assumption of indebtedness or other
consideration, by the Participant in such disposition or other transfer.

     Notices. Any notice to be given under the terms of the Plan to the Company shall be
addressed to the Company in care of its Secretary and any notice to be given to any Participant
shall be addressed to such Participant at such Participant’s last address as reflected in the
Company’s records. By a notice given pursuant to this Section, either party may designate a
different address for notices to be given to it, him or her. Any notice which is required to be
given to a Participant shall, if the Participant is then deceased, be given to the Participant’s
personal representative if such representative has previously informed the Company of his status
and address by written notice under this Section. Any notice shall have been deemed duly given if
enclosed in a properly sealed envelope or wrapper addressed as aforesaid at the time it is
deposited (with postage prepaid) in a post office or branch post office regularly maintained by the

          Additional Restrictions. The terms and conditions of Options granted under the Plan
to, and the purchase of shares of Stock by, persons subject to Section 16 of the Exchange Act shall
comply with the applicable provisions of Rule 16b-3 of the Exchange Act. This Plan shall be deemed
to contain, and such Options shall contain, and the shares of Stock issued upon exercise thereof
will be subject to, such additional conditions and restrictions as may be required by Rule 16b-3 of
the Exchange Act to qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

          Equal Rights and Privileges. All Eligible Employees of the Company (or of any
Designated Subsidiary Corporation) will have equal rights and privileges under this Plan so that
this Plan qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the
Code or applicable Treasury regulations thereunder. Any provision of this Plan that is
inconsistent with Section 423 or applicable Treasury regulations will, without further act or
amendment by the Company or the Board, be reformed to comply with the equal rights and privileges
requirement of Section 423 or applicable Treasury regulations.

          Information to Participants. To the extent required by Section 260.140.46 of Title 10
of the California Code of Regulations, the Company shall provide to each Participant, not less
frequently than annually during the period such Participant has one or more Options outstanding,
and, in the case of an individual who acquires Stock pursuant to the Plan, during the period such
individual owns such Stock, copies of annual financial statements. Notwithstanding the preceding
sentence, the Company shall not be required to provide such statements to key employees whose
duties in connection with the Company assure their access to equivalent information.

          Compliance with Laws. The Plan, the granting and vesting of Options under the Plan
and the issuance and delivery of shares of Stock and the payment of money under the Plan or under
Options granted or

awarded hereunder are subject to compliance with all applicable federal and state laws, rules
and regulations (including but not limited to state and federal securities law and federal margin
requirements) and to such approvals by any listing, regulatory or governmental authority as may, in
the opinion of counsel for the Company, be necessary or advisable in connection therewith. Any
securities delivered under the Plan shall be subject to such restrictions, and the person acquiring
such securities shall, if requested by the Company, provide such assurances and representations to
the Company as the Company may deem necessary or desirable to assure compliance with all applicable
legal requirements. To the extent permitted by applicable law, the Plan and Options granted or
awarded hereunder shall be deemed amended to the extent necessary to conform to such laws, rules
and regulations.

Eligible Employee may submit (i) an Authorization in accordance with Section 3(b) or Section 6(b),
(ii) an election to increase, decrease or suspend payroll deductions in accordance with Section
3(b), (iii) a Withdrawal Election in accordance with Section 6(a), or (iv) a designation as to

prepared by the Committee (“Electronic Form”). Prior to the commencement of an Offering Period,
the Committee shall prescribe the time limits within which any Electronic Form shall be submitted
to the Committee with respect to such Offering Period in order to be a valid election.

          With respect to an Authorization by means of Electronic Form in accordance with Section 3(b)
or Section 6(b), the Committee shall provide an Eligible Employee who transmits an Electronic Form
with written notice of such Electronic Form and shall request that such Eligible Employee provide
written confirmation of such Electronic Form. If such Eligible Employee fails to provide written
confirmation of such Electronic Form as required by the Committee, the Electronic Form shall
terminate and shall be null and void and such Eligible Employee’s cumulative payroll deductions
shall be refunded to such Eligible Employee without any interest thereon.
