losses, cash flows, and the elements thereof), except as set forth in clause (a) of the definition
of Consolidated Net Income.  

ARTICLE 2

The Credits

     Section 2.01   Commitments.  Subject to the terms and conditions set forth herein, each
Lender agrees to make Loans to the Borrower during the Availability Period in an aggregate
principal amount that will not result in (i) such Lender’s Revolving Credit Exposure exceeding such
Lender’s Commitment or (ii) the total Revolving 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.  

     (b)     Types of Loans.  Subject to Section 3.03, each Borrowing shall be comprised
entirely of Canadian Prime Loans, CDOR Loans, U.S.  Prime Loans or Eurodollar Loans as the Borrower
may request in accordance herewith.  Each Lender at its option may make any CDOR Loan or 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.  No such designation or transfer shall
result in any liability on the part of the Borrower for increased costs or expenses resulting
solely from such designation or transfer (except any such transfer which is made by a Lender
pursuant to Section 5.04 or Section 5.05, or otherwise for the purpose of complying with any
Governmental Requirement).  Increased costs for expenses resulting from
a Change in Law occurring subsequent to any such designation or transfer shall be deemed not
to result solely from such designation or transfer.  

30

 

     (c)     Minimum Amounts; Limitation on Number of Borrowings.  Each Canadian Prime
Borrowing shall be in an aggregate amount that is an integral multiple of C$100,000 and not less
than C$500,000; provided that a Canadian Prime 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 2.08(e).  Each CDOR Borrowing shall
be in an aggregate amount that is an integral multiple of C$1,000,000 and not less than
C$3,000,000.  Each U.S.  Prime Borrowing shall be in an aggregate amount that is an integral
multiple of $100,000 and not less than $500,000; provided that a U.S.  Prime 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 2.08(e).  Each Eurodollar Borrowing shall be in an aggregate amount that is an integral multiple of
$1,000,000 and not less than $3,000,000.  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 10 CDOR Borrowings
or 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.  If requested by a Lender, the Loans made 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 Effective Date, and
(ii) any other Lender, as of the date such Lender becomes a party hereto, payable to such Lender in
a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly
completed.  In the event that any Lender’s Maximum Credit Amount increases or decreases for any
reason (whether pursuant to Section 2.06, Section 2.09, Section 12.04(b) or otherwise), the
Borrower shall deliver or cause to be delivered, to the extent such Lender is then holding a Note
and upon the written request of such Lender, on the effective date of such increase or decrease, a
new Note payable to such Lender in a principal amount equal to its Maximum Credit Amount after
giving effect to such increase or decrease, and otherwise duly completed.  Upon receipt of such
replacement Note, such Lender shall return the replaced Note to the Borrower.  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 Canadian Prime Borrowing, a CDOR
Borrowing, a U.S.  Prime Borrowing or a Eurodollar Borrowing, the Borrower shall notify the
Administrative Agent of such request by telephone (a) in the case of a CDOR Borrowing or a
Eurodollar Borrowing, not later than 1:00 p.m., Toronto time, three Business Days before the date
of the proposed Borrowing or (b) in the case of a Canadian Prime Borrowing or a U.S.  Prime
Borrowing, not later than 12:00 p.m.  noon, Toronto time, on the date of the proposed Borrowing;
provided that no such notice shall be required for any deemed request of a Canadian Prime Borrowing
or a U.S.  Prime Borrowing, as applicable, to finance the reimbursement of an LC Disbursement as
provided in Section 2.08(e).  Each such telephonic Borrowing Request shall be irrevocable and shall
be confirmed promptly by hand delivery, electronic mail or telecopy to the Administrative Agent of
a written Borrowing Request substantially in 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:

     (i)     the aggregate amount of the requested Borrowing (which amount will be in the
appropriate Currency as required pursuant to the third to last sentence of this Section
2.03);

31

 

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

     (iii)     whether such Borrowing is to be a Canadian Prime Borrowing, a CDOR Borrowing, a
U.S.  Prime Borrowing or a Eurodollar Borrowing;

     (iv)     in the case of a CDOR Borrowing or 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 location and number of the Borrower’s account to which funds are to be
disbursed, which shall comply with the requirements of Section 2.05.  

     If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be
a Canadian Prime Borrowing.  If no Interest Period is specified with respect to any requested CDOR
Borrowing or Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest
Period of one month’s duration.  Notwithstanding anything herein to the contrary, (x) Canadian Prime
Loans and CDOR Loans may only be denominated in Canadian Dollars and (y) U.S.  Prime Loans and
Eurodollar Loans may only be denominated in Dollars.  Each Borrowing Request shall be deemed to
constitute a representation and warranty by the Borrower that the matters specified in Section
6.02(a) through (d) will be satisfied on the date of Borrowing specified in such Borrowing Request.  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   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 CDOR Borrowing or 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 CDOR Borrowing or a
Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.04.  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 among the Lenders holding the
Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a
separate Borrowing.  No such conversion or continuation shall be deemed the making of a new
Borrowing for purposes of this Agreement, including without limitation Article 6.  

     (b)     Interest Election Requests.  To make an election pursuant to this Section 2.04,
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, electronic mail or telecopy 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 2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing);

32

 

     (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 a Canadian Prime Borrowing, a CDOR
Borrowing, a U.S.  Prime Borrowing or a Eurodollar Borrowing; and

     (iv)     if the resulting Borrowing is a CDOR Borrowing or a Eurodollar Borrowing, the
Interest Period to be applicable thereto after giving effect to such election, which, subject
to Section 2.04(e)(ii), shall be a period contemplated by the definition of the term
“Interest Period”.  

     If any such Interest Election Request requests a CDOR Borrowing or a Eurodollar Borrowing but
does not specify an Interest Period or the Interest Period specified in such Interest Election
Request is not available to all Lenders, then the Borrower shall be deemed to have selected an
Interest Period of one 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
and Borrowing Base Deficiencies on Interest Election.  If the Borrower fails to deliver a
timely Interest Election Request with respect to a CDOR Borrowing or 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 a Canadian
Prime Borrowing or U.S.  Prime Borrowing, as applicable.  Notwithstanding any contrary provision
hereof, if (i) an Event of Default has occurred and is continuing and the Administrative Agent, at
the request of the Majority Lenders, so notifies the Borrower: (A) no outstanding Borrowing may be
converted to or continued as a CDOR Borrowing or a Eurodollar Borrowing (and any Interest Election
Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a
CDOR Borrowing or a Eurodollar Borrowing shall be ineffective) and (B) unless repaid, each CDOR
Borrowing and Eurodollar Borrowing shall be converted to a Canadian Prime Borrowing or a U.S.  Prime
Borrowing, as applicable, at the end of the Interest Period applicable thereto and (ii) a Borrowing
Base Deficiency exists and the Administrative Agent, at the request of the Majority Lenders, so
notifies the Borrower, no outstanding Borrowing may be converted to or continued as a CDOR
Borrowing or a Eurodollar Borrowing with an Interest Period longer than one month.  

     Section 2.05   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 (in the appropriate
Currency based on the relevant Borrowing Request) by 2:00 p.m., Toronto time, to the account of the
Administrative Agent most recently designated by it for such purpose by notice to the Lenders.  The
Administrative Agent will make such Loans available to the Borrower by promptly crediting the
amounts so received, in like funds, to an account of the Borrower maintained with the
Administrative Agent and designated by the Borrower in the applicable Borrowing Request; provided
that Canadian Prime Loans or U.S.  Prime Loans, as applicable, made to finance the reimbursement of
an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to
the Issuing Bank that made such LC Disbursement.  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.  

33

 

     (b)     Presumption of Funding by the Lenders.  Unless the Administrative Agent shall have
received notice from a Lender prior to the proposed date (or with respect to a Canadian Prime
Borrowing or a U.S.  Prime Borrowing, prior to the proposed time) of any 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 2.05(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 and the
Borrower severally agree 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 (i)
in the case of such Lender, the greater of the costs incurred by the Administrative Agent for
making such Lender’s share of such Borrowing and a rate determined by the Administrative Agent in
accordance with banking industry rules on interbank compensation or (ii) in the case of the
Borrower, the interest rate applicable to Canadian Prime Loans.  If such Lender pays such amount to
the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such
Borrowing.  

     (c)     Borrowings, conversion or continuations of Loans, and prepayments of Loans of different
Currencies at the same time hereunder shall be deemed to be separate Borrowings, continuations,
conversions and prepayments, respectively, one for each Currency.  

     Section 2.06   Termination and Reduction of Aggregate Maximum Credit Amounts.  (a)
Scheduled Termination of Commitments.  Unless previously terminated, the Commitments shall
terminate on the Maturity Date.  If at any time the Aggregate Maximum Credit Amounts are terminated
or reduced to zero, then the Commitments shall terminate on the effective date of such termination
or reduction.  

     (b)     Optional Termination and Reduction of Aggregate Credit Amounts.  (i) The Borrower
may at any time terminate, or from time to time reduce, the Aggregate Maximum Credit Amounts;
provided that (A) each reduction of the Aggregate Maximum Credit Amounts shall be in an amount that
is an integral multiple of C$1,000,000 and not less than C$3,000,000 and (B) the Borrower shall not
terminate or reduce the Aggregate Maximum Credit Amounts if, after giving effect to any concurrent
prepayment of the Loans in accordance with Section 3.04(c), the total Revolving Credit Exposures
would exceed the total Commitments.  

     (ii)     The Borrower shall notify the Administrative Agent of any election to terminate or
reduce the Aggregate Maximum Credit Amounts under Section 2.06(b)(i) at least three 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 2.06(b)(ii) shall be irrevocable; provided that a notice of
termination of the Aggregate Maximum Credit Amounts 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.  Any termination or
reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be
reinstated.  Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably
among the Lenders in accordance with each Lender’s Applicable Percentage.  

34

 

     Section 2.07   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 C$225,000,000.  Notwithstanding the foregoing, the Borrowing Base may be
subject to further adjustments from time to time, whether before or after such Redetermination
Date, pursuant to Section 9.02(n) or Section 9.10.  

     (b)     Scheduled and Interim Redeterminations.  Subject to Section 2.07(d), the Borrowing
Base shall be redetermined semi-annually (a “Scheduled Redetermination”) on or about the
date that is 45 days following the Borrower’s delivery of a Reserve Report in accordance with
Section 8.11(a).  In addition, (i) the Borrower may, by notifying the Administrative Agent thereof,
and (ii) the Administrative Agent may, at the direction of the Required Lenders, by notifying the
Borrower thereof, each elect to cause the Borrowing Base to be redetermined one time between
Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section
2.07.  

     (c)     Scheduled and Interim Redetermination Procedure.  (i) Each Scheduled
Redetermination and each Interim 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 8.11(a) and (c), and, in the case of an Interim Redetermination, pursuant to Section
8.11(b) and (c), and (B) such other reports, data and supplemental information including, without
limitation, the information provided pursuant to Section 8.11(c) as may, from time to time, be
reasonably requested by the Required 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
propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information
and such other information that is deemed appropriate by the Administrative Agent in its sole
discretion in good faith and consistent with its normal oil and gas lending criteria as it exists
at the particular time (including, without limitation, the status of title information with
respect to the Oil and Gas Properties as described in the Engineering Reports, if applicable, and
the existence of any other Debt, the Borrower’s other assets, liabilities, fixed charges, cash
flow, business, properties, prospects, management and ownership, hedged and unhedged exposure to
price, price and production scenarios, interest rate and operating cost changes).  In no event
shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amounts.  

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

     (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 8.11(a) in a timely and complete manner, then on or before 30
days after the receipt of such Engineering Reports (or as promptly thereafter as may
be reasonably practicable) or (2) if the Administrative Agent shall not have
received the Engineering Reports required to be delivered by the Borrower pursuant
to Section 8.11(a) 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 2.07(c)(i); and

     (B)     in the case of an Interim Redetermination, promptly, and in any event,
within 30 days after the Administrative Agent has received the required Engineering
Reports (or as promptly thereafter as may be reasonably practicable).  

35

 

     (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 2.07(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 2.07(c)(iii).  Upon receipt of the Proposed
Borrowing Base Notice, each Lender shall have 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 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 2.07(d).  If, however, at the end of such 15-day period, the
Required Lenders, in the case of a decrease or reaffirmation of the Borrowing Base, or all
Lenders, in the case of an increase to the Borrowing Base, 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 all Lenders, in the case of an
increase to the Borrowing Base, or to a number of Lenders sufficient to constitute the
Required Lenders, in the case of a decrease or reaffirmation of the Borrowing Base, and such
amount shall become the new Borrowing Base, effective on the date specified in Section
2.07(d).  The consent of the Borrower, in its sole discretion, shall be required for any
increase in the Borrowing Base.  

     (d)     Effectiveness of a Redetermined Borrowing Base.  After a redetermined Borrowing
Base is approved or is deemed to have been approved by the Required Lenders or all Lenders, as
applicable, pursuant to Section 2.07(c)(iii) (and, in the case of an increase, the Borrower), 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 amounts shall become the new
Borrowing Base, effective and applicable to the Borrower, the Agents, each Issuing Bank and the
Lenders:

     (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 8.11(a) and (c) in a timely and complete manner, then on the date of such New
Borrowing Base Notice, or (B) if the Administrative Agent shall not have received the
Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and
(c) in a timely and complete manner, then on the Business Day next succeeding the date of
such New Borrowing Base Notice; and

     (ii)     in the case of an Interim Redetermination, on the Business Day next succeeding the
date of such New Borrowing Base 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 9.02(n) or Section 9.10, whichever occurs first.  Notwithstanding the foregoing, no
Scheduled Redetermination or Interim Redetermination shall become effective until the New Borrowing
Base Notice related thereto is received by the Borrower.  

     Section 2.08   Letters of Credit.  

36

 

     (a)     General.  Subject to the terms and conditions set forth herein, the Borrower may
request any Issuing Bank to issue Canadian Dollar or 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 such Issuing Bank, at any time and from time to time
during the Availability Period; provided, however, that no Letter of Credit shall be issued if,
after such issuance, the LC Exposure would exceed the lesser of (A) the LC Commitment and (B) an
amount equal to the aggregate Commitments minus the aggregate Loans then outstanding.  In the event
of any inconsistency between the terms and conditions of this Agreement and the terms and
conditions of any form of letter of credit application or other agreement submitted by the Borrower
to, or entered into by the Borrower with, an Issuing Bank relating to any Letter of Credit, 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 telecopy (or transmit by electronic communication,
if arrangements for doing so have been approved by the applicable Issuing Bank) to any Issuing Bank
and the Administrative Agent (not less than three 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
issued by such Issuing Bank to be amended, renewed or extended;

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

     (iii)     specifying the date on which such Letter of Credit is to expire (which shall
comply with Section 2.08(c));

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

     (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.  

Each such notice shall be deemed to constitute a representation and warranty by the Borrower that
the matters specified in Section 6.02(a) through (d) will be satisfied on the date specified in
clause (ii) of the immediately preceding sentence and that the LC Exposure will not exceed the LC
Commitment on such date.  No letter of credit issued by an Issuing Bank (if the Issuing Bank is
not the Administrative Agent) shall be deemed to be a “Letter of Credit” issued under this
Agreement unless such Issuing Bank has confirmed with the Administrative Agent that the condition
set forth in Section 6.02(d) hereof is satisfied and that the LC Exposure does not exceed the LC
Commitment (after giving effect to the issuance of such letter of credit).  If requested by any
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 year after the date of the issuance of such Letter of
Credit (or, in the case of any renewal or extension thereof, one year after such renewal or
extension) and (ii) the date that is five Business Days prior to the Maturity Date; provided,
however, that any Letter of Credit with a one-year tenor may provide for the renewal thereof for
additional one-year periods (which shall in no event extend beyond the date referred to in clause
(ii) above).  

37

 

     (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 the
Issuing Bank that issues such Letter of Credit or the Lenders, each Issuing Bank that issues a
Letter of Credit hereunder 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, in the Currency in which such Letter of Credit is denominated, for the
account of any Issuing Bank that issues a Letter of Credit hereunder, such Lender’s Applicable
Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on
the date due as provided in Section 2.08(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 2.08(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 issued by such Issuing Bank, the Borrower shall reimburse such LC Disbursement by
paying to the Administrative Agent an amount (in the Currency in which the applicable Letter of
Credit is denominated) equal to such LC Disbursement not later than 2:00 p.m., Toronto time, on the
date that such LC Disbursement is made, if the Borrower shall have received notice of such LC
Disbursement prior to 11:00 a.m., Toronto 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 2:00 p.m., Toronto
time, on (i) the Business Day that the Borrower receives such notice, if such notice is received
prior to 11:00 a.m., Toronto 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 may request that such payment be
financed with a Canadian Prime Borrowing (with respect to Letters of Credit denominated in Canadian
Dollars) or a U.S.  Prime Borrowing (with respect to Letters of Credit denominated in Dollars) 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 Canadian Prime Borrowing or U.S.  Prime Borrowing,
as applicable.  For purposes of the first sentence of Section 2.01, the amount of such Canadian
Prime Borrowing or U.S.  Prime Borrowing, as applicable, shall be considered, but the amount of the
LC Disbursement to be concurrently reimbursed shall not be considered.  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 with respect to Loans made by such Lender (and Section
2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the
Administrative Agent shall promptly pay to the Issuing Bank that issued such Letter of Credit 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 2.08(e), the Administrative Agent shall
distribute such payment to the Issuing Bank that issued such Letter of Credit or, to the extent
that Lenders have made payments pursuant to this Section 2.08(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 2.08(e) to reimburse an Issuing Bank for any LC Disbursement (other
than the funding of Canadian Prime Loans or U.S.  Prime Loans as contemplated above) shall not
constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC
Disbursement.  

38

 

     (f)     Obligations Absolute.  The Borrower’s obligation to reimburse LC Disbursements as
provided in Section 2.08(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, 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 issued by such Issuing Bank against presentation of a
draft or other document that does not 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 2.08(f), constitute a
legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations
hereunder.  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 any 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, the Issuing Bank that issued such Letter of Credit 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.  Each Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment under a Letter of
Credit issued by such Issuing Bank.  Such Issuing Bank shall promptly notify the Administrative
Agent and the Borrower by telephone (confirmed by electronic mail or telecopy) 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 2.08(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 (x) Canadian
Prime Loans (if the related Letter of Credit was denominated in Canadian Dollars) or (y) U.S.  Prime
Loans (if the related Letter of Credit was denominated in Dollars).  Interest accrued pursuant to
this Section 2.08(h) shall be for the account of such Issuing Bank, except that interest accrued on
and after the date of payment by any

39

 

Lender pursuant to Section 2.08(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 or resign at any
time by written agreement among the Borrower, the Administrative Agent, such retiring or replaced
Issuing Bank and, in the case of a replacement, the successor Issuing Bank.  The Administrative
Agent shall notify the Lenders of any such resignation or replacement of an Issuing Bank.  At the
time any such resignation or replacement shall become effective, the Borrower shall pay all unpaid
fees accrued for the account of the retiring or replaced Issuing Bank pursuant to Section 3.05(b).  In the case of the replacement of an Issuing Bank, from and after the effective date of such
replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the
replaced Issuing Bank under this Agreement with respect to Letters of Credit to be issued
thereafter and (ii) references herein to “Issuing Bank” shall be deemed to refer to such successor
or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the
context shall require.  After the resignation or replacement of an Issuing Bank hereunder, the
retiring or 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 resignation or 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 2.08(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 (in the applicable Currency) 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 Guarantor described in
Section 10.01(h) or Section 10.01(i).  The Borrower hereby grants to the Administrative Agent, for
the benefit of each Issuing Bank 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 2.08(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 any Credit Party 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.  Such deposit shall be held as collateral securing the payment and performance of the Credit
Parties’ 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 Credit
Parties’ risk and expense, such deposits shall not bear interest.  Interest or profits, if any, on
such investments shall accumulate in such

40

 

account.  Moneys in such account shall be applied by the Administrative Agent to reimburse, on
a pro rata basis, each Issuing Bank for LC Disbursements for which it has not been reimbursed and,
to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations
of the Credit Parties for the LC Exposure at such time or, if the maturity of the Loans has been
accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors under this
Agreement or the other Loan Documents.  In the event of any such payment by the Borrower of amounts
contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or
other demands for payment complying with the terms of such Letters of Credit are not made on or
prior to the respective expiration dates thereof, the Administrative Agent agrees, if no Default is
then continuing and the Borrower does not have any obligation at such time to provide cash
collateral under Section 2.10 hereof, or if no other amounts are then outstanding under this
Agreement, the Notes or the Loan Documents, to remit to the Borrower amounts for which the
contingent obligations evidenced by the Letters of Credit have ceased (but only to the extent of
the amount of cash collateral then on deposit with the Administrative Agent in respect of such
Letters of Credit).  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 Business Days after all Events of Default have been
cured or waived.  

     Section 2.09   Increase in the Maximum Credit Amounts.  (a) The Borrower may, with the
consent of the Administrative Agent (such consent not to be unreasonably withheld, conditioned or
delayed), on no more than five occasions during the period beginning on the Effective Date to and
including the date that is six months prior to the Maturity Date, by written notice to the
Administrative Agent executed by the Borrower and one or more financial institutions (any such
financial institution executing such notice being called an “Increasing Lender”), which may
include any Lender, cause the Maximum Credit Amounts to be extended by the Increasing Lenders if
such Increasing Lender is not already a Lender (or cause the Maximum Credit Amounts of the
Increasing Lenders that are already Lenders to be increased, as the case may be) in an amount for
each Increasing Lender set forth in such notice; provided, that (i) each extension of new Maximum
Credit Amounts or increase in existing Maximum Credit Amounts pursuant to this paragraph shall
result in the aggregate Maximum Credit Amounts being increased by no less than C$13,000,000, (ii)
the sum of all new Maximum Credit Amounts and increases in existing Maximum Credit Amounts pursuant
to this paragraph shall not exceed C$250,000,000 without the approval of all Lenders, (iii) each
Increasing Lender, if not already a Lender, shall be subject to the approval of the Administrative
Agent, and each Issuing Bank (which approval shall not be unreasonably withheld, conditioned or
delayed), (iv) each Increasing Lender, if not already a Lender hereunder, shall become a party to
this Agreement by completing and delivering to the Administrative Agent a duly executed joinder
agreement in a form reasonably satisfactory to the Administrative Agent and the Borrower (a
“Joinder Agreement”), (v) any Lender requested by the Borrower to become an Increasing
Lender may elect, or decline, such request in its sole discretion and (vi) no Default has occurred
and is continuing.  

     (b)     Upon the effectiveness of any Joinder Agreement to which any Increasing Lender is a party,
(i) such Increasing Lender shall thereafter be deemed to be a party to this Agreement and shall be
entitled to all rights, benefits and privileges accorded a Lender hereunder and subject to all
obligations of a Lender hereunder and (ii) Annex I shall be deemed to have been amended to reflect
the Maximum Credit Amount of such Increasing Lender as provided in such Joinder Agreement.  Upon
the effectiveness of any increase pursuant to this Section 2.09 in the Maximum Credit Amount of a
Lender already a party hereto, Annex I shall be deemed to have been amended to reflect the
increased Maximum Credit Amount of such Lender.  Notwithstanding the foregoing, no increase in the
Aggregate Maximum Credit Amounts (or in the Maximum Credit Amount of any Lender) shall become
effective under this Section unless, on the date of

41

 

such increase, the Administrative Agent shall have received (i) a certificate, dated as of the
effective date of such increase and executed by a Financial Officer of the Borrower, to the effect
that the conditions set forth in paragraphs (a) and (c) of Section 6.02 shall be satisfied (with
all references in such paragraphs to a Borrowing being deemed to be references to such increase and
attaching resolutions of the Borrower approving such increase) and (ii) if requested by the
Administrative Agent, a legal opinion in form and substance reasonably satisfactory to the
Administrative Agent.  The Administrative Agent shall provide notice to the Borrower and the
Lenders of the effectiveness of any such Joinder Agreement and/or any increase in the Aggregate
Maximum Credit Amounts (or in the Maximum Credit Amount of any Lender) and the foregoing shall be
effective as of the date of such notice.  

     (c)     The Borrower shall prepay any Loans outstanding prior to the effectiveness of such
increase or extension, together with any amounts due pursuant to Section 5.02, with new Loans made
pursuant to Section 2.01 ratably in accordance with the Maximum Credit Amounts in effect following
such extension or increase.  

     Section 2.10   Defaulting Lenders.  Notwithstanding any provision of this Agreement to
the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply
for so long as such Lender is a Defaulting Lender:

     (a)     Commitment fees will cease to accrue on the unfunded portion of the Commitment of the
Defaulting Lender pursuant to Section 3.05(a) and such Defaulting Lender shall not be entitled to
receive any commitment fee pursuant to Section 3.05(a);

     (b)     If any LC Exposure exists at the time a Lender is a Defaulting Lender then solely for
purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire,
refinance or fund participations in Letters of Credit pursuant to Section 2.08:

     (i)     all or any part of the LC Exposure of such Defaulting Lender shall be reallocated
among the non-Defaulting Lenders in accordance with their respective Applicable Percentages
but only to the extent that (x) the sum of all non-Defaulting Lenders’ Revolving Credit
Exposures does not exceed the total of all non-Defaulting Lenders’ Commitments, (y) each
non-Defaulting Lender’s total Revolving Credit Exposure may not in any event exceed the
Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and
(z) the conditions set forth in Section 6.02 are satisfied at such time;

     (ii)     if the reallocation described in clause (i) above cannot, or can only partially, be
effected, the Borrower shall within three Business Days following notice by the
Administrative Agent given no later than 1:00 p.m., Toronto time cash collateralize such
Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to
clause (i) above) in accordance with the procedures set forth in Section 2.08(j) for so long
as such LC Exposure is outstanding;

     (iii)     if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC
Exposure pursuant to this Section 2.10(b), the Borrower shall not be required to pay any fees
to such Defaulting Lender pursuant to Section 3.05(b) with respect to such Defaulting
Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash
collateralized; if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to
this Section 2.10, then the fees payable to the Lenders pursuant to Section 3.05(a) and
Section 3.05(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable
Percentages with the balance of such fee, if any, being retained by the Borrower for its own
account or, to the extent any LC Exposure

42

 

shall then be outstanding, being payable to each
applicable Issuing Bank for its own account to the extent such fee relates to the amount of
such LC Exposure; or

     (iv)     if any Defaulting Lender’s LC Exposure is neither cash collateralized nor
reallocated pursuant to this Section 2.10, then, without prejudice to any rights or remedies
of any Issuing Bank or any Lender hereunder, all commitment fees that otherwise would have
been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting
Lender’s Commitment that was utilized by such LC Exposure) and Letter of Credit fees payable
under Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure shall be payable
to each applicable Issuing Bank until such LC Exposure is cash collateralized and/or
reallocated.  

     (c)     Notwithstanding any provision of this Agreement to the contrary, so long as any Lender is
a Defaulting Lender, no Issuing Bank shall be required to issue, amend or increase any Letter of
Credit unless it is satisfied that the related exposure will be 100% covered by the Commitments of
the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance
with Section 2.08(j), and participating interests in any such newly issued or increased Letter of
Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section
2.10(b)(i) (and Defaulting Lenders shall not participate therein).  

     (d)     Any amount payable to such Defaulting Lender hereunder (whether on account of principal,
interest, fees or otherwise and including any amount that would otherwise be payable to such
Defaulting Lender pursuant to Section 4.01(c) or Section 10.02(c), but excluding Section 5.04(b))
will, in lieu of being distributed to such Defaulting Lender, be retained by the Administrative
Agent in a segregated account and, subject to any applicable requirements of law, be applied at
such time or times as may be determined by the Administrative Agent (i) first, to the payment of
any amounts owing by such Defaulting Lender to the Administrative Agent hereunder, (ii) second, pro
rata, to the payment of any amounts owing by such Defaulting Lender to each Issuing Bank hereunder,
(iii) third, to cash collateralize such Defaulting Lender’s LC Exposure in accordance with Section
2.08(j), (iv) fourth, as the Borrower may request (so long as no Default exists), to the funding of
any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as
required by this Agreement, as determined by the Administrative Agent, (v) fifth, if so determined
by the Administrative Agent and the Borrower, held in an interest bearing account and released pro
rata in order to (A) satisfy such Defaulting Lender’s potential future funding obligations with
respect to Loans under this Agreement and (B) cash collateralize such Defaulting Lender’s future LC
Exposure in accordance with Section 2.08(j), (vi) sixth, to the payment of any amounts then owing
to the Lenders or any Issuing Bank as a result of any final and non-appealable judgment of a court
of competent jurisdiction obtained by any Lender or Issuing Bank against such Defaulting Lender as
a result of such Defaulting Lender’s breach of its obligations under this Agreement, (vii) seventh,
to the payment of any amounts then owing to the Borrower as a result of any final and
non-appealable judgment of a court of competent jurisdiction obtained by the Borrower against such
Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this
Agreement and (viii) eighth, to such Defaulting Lender or as otherwise directed by a court of
competent jurisdiction; provided that if such payment is (x) a prepayment of the principal amount
of any Loans or reimbursement obligations in respect of LC Disbursement that a Defaulting Lender
has not fully funded its participation obligations and (y) in the case of such Loans which were
made at a time when the conditions set forth in Section 6.02 were satisfied or waived, such payment
will be applied solely to prepay the Loans of, and reimbursement obligations owed to, all
non-Defaulting Lenders pro rata prior to being applied to the prepayment of any Loans, or
reimbursement obligations owed to, any Defaulting Lender.  Any payments, prepayments or other
amounts paid or payable to any Defaulting Lender that are applied (or held) to pay amounts owed by
such Defaulting Lender or to post cash collateral pursuant to Section 2.10 shall be

43

 

deemed paid to
and redirected by such Defaulting Lender, and each Lender irrevocably consents to the foregoing.  

     (e)     If any Lender is a Defaulting Lender, then the Borrower may, at its sole expense and
effort, upon notice to such Lender and the Administrative Agent, require such Lender to be replaced
in accordance with Section 5.04(b).  

     (f)     In the event that the Administrative Agent, the Borrower and the Issuing Banks each agrees
that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a
Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion
of such Defaulting Lender’s Commitment and on such date such Defaulting Lender shall purchase at
par such of the Loans of the other Lenders as the Administrative Agent shall determine may be
necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage;
provided, that no adjustments will be made retroactively with respect to fees accrued or payments
made by or on behalf of the Borrower while such Lender was a Defaulting Lender; and provided,
further, that except to the extent otherwise expressly agreed by the affected parties, no change
hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim that
the Borrower, the Administrative Agent, the Issuing Banks, or any other Lender may have against
such Defaulting Lender or cause such Defaulting Lender to be a non-Defaulting Lender except as
expressly set forth above.  

     Section 2.11   Currency Conversion and Currency Indemnity.  

     (a)     Payments in Agreed Currency.  The Borrower shall, and shall cause the other Credit
Parties to, make payment relative to any Secured Indebtedness in the currency (the “Agreed
Currency”) in which such Secured Indebtedness was effected.  If any payment is received on
account of any Secured Indebtedness in any currency (the “Other Currency”) other than the
Agreed Currency (whether voluntarily or pursuant to an order or judgment or the enforcement thereof
or the realization of any collateral under the Security Instruments or the liquidation of the
Borrower or otherwise howsoever), such payment shall constitute a discharge of the liability of the
Credit Parties hereunder and under the other Loan Documents in respect of such obligation only to
the extent of the amount of the Agreed Currency which the relevant Lender or Agent, as the case may
be, is able to purchase with the amount of the Other Currency received by it on the Business Day
next following such receipt in accordance with its normal procedures and after deducting any
premium and costs of exchange.  

     (b)     Conversion of Agreed Currency into Judgment Currency.  If, for the purpose of
obtaining or enforcing judgment in any court in any jurisdiction, it becomes necessary to convert
into a particular currency (the “Judgment Currency”) any amount due in the Agreed Currency
then the conversion shall be made on the basis of the rate of exchange prevailing on the next
Business Day following the date such judgment is given and in any event any Credit Party shall be
obligated to pay the Agents and the Lenders any deficiency in accordance with Section 2.11(c).  For
the foregoing purposes “rate of exchange” means the lowest rate at which the relevant Lender or
Agent, as applicable, in accordance with its normal banking procedures is able on the relevant date
to purchase the Agreed Currency with the Judgment Currency after deducting any premium and costs of
exchange.  

     (c)     Circumstances Giving Rise to Indemnity.  To the fullest extent permitted by
applicable law, if (i) any Lender or any Agent receives any payment or payments on account of the
liability of the Borrower hereunder pursuant to any judgment or order in any Other Currency, and
(ii) the amount of the Agreed Currency which the relevant Lender or Agent, as applicable, is able
to purchase on the Business Day next following such receipt with the proceeds of such payment or
payments in accordance with its normal procedures and after deducting any premiums and costs of
exchange is less than the amount of the

44

 

Agreed Currency due in respect of such liability
immediately prior to such judgment or order, then the Borrower on demand shall, and the Borrower
hereby agrees to, indemnify the Lenders and the Agents from and against any loss, cost or expense
arising out of or in connection with such deficiency; provided
that if the amount of the Agreed Currency so purchased is greater than the amount of the
Agreed Currency due in respect of such liability immediately prior to such judgment or order, then
the Agents or the Lenders, as the case may be, agree to return the amount of any excess to the
Borrower (or to any other Person who may be entitled thereto under applicable law).  

     (d)     Indemnity Separate Obligation.  To the fullest extent permitted by applicable law,
the agreement of indemnity provided for in Section 2.11(c) shall constitute an obligation separate
and independent from all other obligations contained in this Agreement, shall give rise to a
separate and independent cause of action, shall apply irrespective of any indulgence granted by the
Lenders or Agents or any of them from time to time, and shall continue in full force and effect
notwithstanding any judgment or order for a liquidated sum in respect of an amount due hereunder or
under any judgment or order.  

     (e)     Other Currency Conversion.  Any amount of money to be used in determining
compliance with this Agreement may be denominated in either $ or C$ and, in accordance with such
determination, may be converted from $ to C$ or vice-versa, as applicable, at the then-current rate
of exchange on the date thereof.  For the foregoing purposes “rate of exchange” means the rate at
which the Borrower or any other Credit Party, as applicable, in accordance with its normal business
procedures is able on the relevant date to purchase the relevant currency after deducting any
premium and costs of exchange.  

ARTICLE 3

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)     Canadian Prime Loans.  The Loans comprising each Canadian Prime Borrowing shall
bear interest at the Canadian Base Rate plus the Applicable Margin for Canadian Prime Loans, but in
no event to exceed the Highest Lawful Rate.  

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

     (c)     U.S.  Prime Loans.  The Loans comprising each U.S.  Prime Borrowing shall bear
interest at the U.S.  Base Rate plus the Applicable Margin for U.S.  Prime Loans, but in no event to
exceed the Highest Lawful Rate.  

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

     (e)     Default Rate.  Notwithstanding the foregoing, but subject to Sections 3.02(h), (i)
and (j), if any principal of or interest on any Loan or any fee or other amount payable by the
Borrower or any

45

 

Guarantor hereunder or under any other Loan Document is not paid when due, whether
at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after
as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of
any Loan, the lesser of (A) the rate otherwise applicable to such Loan as provided in the preceding
paragraphs of this Section plus 2% or (B)
the Highest Lawful Rate or (ii) in the case of any other amount, the lesser of (A) the Default
Rate or (B) the Highest Lawful Rate.  

     (f)     Interest Payment Dates.  Subject to Sections 3.02(h), (i) and (j), 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(e) shall be
payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than an
optional prepayment of a Canadian Prime Loan or a U.S.  Prime 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 CDOR Loan or 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 (but only to the extent so converted).  

     (g)     Interest Rate Computations.  Subject to Sections 3.02(h), (i) and (j), 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 (i) interest computed by reference to
the U.S.  Base Rate at times when the U.S.  Base Rate is based on the U.S.  Prime Rate and (ii)
interest computed by reference to the Canadian Base Rate or the CDOR 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
Canadian Base Rate, CDOR Rate, U.S.  Base 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.  

     (h)     To the extent permitted by applicable law, any provision of the Interest Act (Canada) or
the Judgment Interest Act (Alberta) which restricts any rate of interest set forth herein shall be
inapplicable to this Agreement and is hereby waived by the Borrower.  

     (i)     The theory of deemed reinvestment shall not apply to the calculation of interest or
payment of fees or other amounts hereunder, notwithstanding anything contained in this Agreement,
acceptance or other evidence of indebtedness or in any other Loan Document now or hereafter taken
by any Agent or any Lender for the obligations of the Borrower under this Agreement, or any other
instrument referred to herein, and all interest and fees payable by the Borrower to the Lenders,
shall accrue from day to day, computed as described herein in accordance with the “nominal rate”
method of interest calculation.  

     (j)     Where, in this Agreement, a rate of interest or fees is to be calculated on the basis of a
365/366-day year, such rate is, for the purpose of the Interest Act (Canada), equivalent to the
said rate (i) multiplied by the actual number of days in the one year period beginning on the first
day of the period of calculation and (ii) divided by 365 or 366, as applicable.  

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

46

 

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

     (b)     the Administrative Agent is advised by the Majority Lenders that the CDOR Rate or the 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, electronic mail or telecopy 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 CDOR Borrowing or a Eurodollar Borrowing, as
applicable, shall be ineffective, and (ii) if any Borrowing Request requests a CDOR Borrowing or a
Eurodollar Borrowing, as applicable, such Borrowing shall be made as a Canadian Prime 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).  

     (b)     Notice and Terms of Optional Prepayment.  The Borrower shall notify the
Administrative Agent by telephone (confirmed by electronic mail or telecopy) of any prepayment
hereunder (i) in the case of prepayment of a CDOR Borrowing or a Eurodollar Borrowing, not later
than 1:00 p.m., Toronto time, three Business Days before the date of prepayment, or (ii) in the
case of prepayment of a Canadian Prime Borrowing or a U.S.  Prime Borrowing, not later than 1:00
p.m., Toronto time, one Business Day before the date of prepayment.  Each such notice shall be
irrevocable and shall specify the Borrowing to be prepaid, 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 2.06(b), then such notice of prepayment may be revoked if such notice of termination is
revoked in accordance with Section 2.06(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.  The Administrative Agent
shall apply each prepayment of a Borrowing ratably to the Loans included in the Borrowing specified
in the Borrower’s notice of prepayment.  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 Aggregate Maximum
Credit Amounts pursuant to Section 2.06(b), the total Revolving Credit Exposures exceeds the
total Commitments, then the Borrower shall (A) prepay the Borrowings on the date of such
termination or reduction in an aggregate principal amount equal to such excess, and (B) if
any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay
to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be
held as cash collateral as provided in Section 2.08(j).  

47

 

     (ii)     Upon any redetermination of or adjustment to the amount of the Borrowing Base in
accordance with Section 2.07 or Section 9.10 (solely as a result of a Casualty Event), if the
total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then
the Borrower shall, at its option, either (A) make (or cause to be made) a single payment of
principal in an amount equal to such Borrowing Base Deficiency and, if any Borrowing Base
Deficiency remains after prepaying all of the Borrowings as a result of an LC Exposure, pay
to the Administrative Agent on behalf of the Lenders an amount equal to such remaining excess
to be held as cash collateral as provided in Section 2.08(j), in each case, within thirty
(30) days following its receipt of the New Borrowing Base Notice in accordance with Section
2.07(d) or the date the adjustment occurs (the “Deficiency Notification Date”), (B)
make (or cause to be made) six payments of principal each of which shall be in an amount
equal to one-sixth (1/6th) of such Borrowing Base Deficiency commencing on the 15th day of a
calendar month that is at least thirty (30) days following the Deficiency Notification Date
and on the 15th day of each of the five calendar months thereafter, (C) within forty-five
(45) days following the Deficiency Notification Date, submit (and pledge as Collateral)
additional Oil and Gas Properties owned by a Credit Party which is or shall become a
Guarantor contemporaneously with such submission pursuant to Section 8.13, which Oil and Gas
Properties (x)(1) are located in British Columbia, Alberta or in another province in Canada
that at such time allows for a secured lender to receive the benefit of a floating charge
over real property located in such province and (2) were not previously subject to a floating
charge in favor of the Administrative Agent, or (y) are located in any other province in
Canada, the United States or any other country or jurisdiction reasonably acceptable to the
Administrative Agent; provided that with respect to Oil and Gas Properties submitted and
pledged pursuant to this clause (y), (1) the Administrative Agent shall be reasonably
satisfied that fixed charges, collateral agreements or other Security Instruments create
first priority, perfected Liens (subject only to Permitted Liens) on at least 80% of the
total value of the Proved Hydrocarbon Interests relating to such Oil and Gas Properties
(including any such Oil and Gas Properties subject to floating charges) and (2) the
Administrative Agent shall have received title information as the Administrative Agent may
reasonably require satisfactory to the Administrative Agent setting forth the status of title
to at least 75% of the total value of such Oil and Gas Properties, in either case, for
consideration in connection with the determination of the Borrowing Base which the
Administrative Agent and the Required Lenders deem satisfactory, in their sole discretion, to
eliminate such Borrowing Base Deficiency or (D) within thirty (30) or forty-five (45) days
following the Deficiency Notification Date, as applicable, eliminate such Borrowing Base
Deficiency through a combination of a payment and submission of additional Oil and Gas
Properties as set forth in clauses (A) and (C) above; provided that all payments required to
be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination
Date.  Not later than 15 days following the Deficiency Notification Date, the Borrower shall
provide written notice to the Administrative Agent setting forth its election pursuant to the
immediately preceding sentence.  

     (iii)     Upon any adjustments to the Borrowing Base pursuant to Section 9.02(n) or Section
9.10 (other than adjustments resulting directly from Casualty Events), if the total Revolving
Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay
the Borrowings in an aggregate principal amount equal to such Borrowing Base Deficiency, and
(B) if any excess remains after prepaying all of the Borrowings as a result of an LC
Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such
excess to be held as cash collateral as provided in Section 2.08(j).  The Borrower shall be
obligated to make such prepayment and/or deposit of cash collateral (x) within thirty (30)
days following the effective date of any such adjustment to the Borrowing Base under Section
9.02(n) or (y) prior to or contemporaneously with such adjustment to the Borrowing Base under
Section 9.10 (other than

48

 

adjustments resulting directly from Casualty Events); provided that
all payments required to be made pursuant to this Section 3.04(c)(iii) must be made on or
prior to the Termination Date.  

     (iv)     If, as a result of any currency fluctuation, the total Revolving Credit Exposures
exceeds 105% of the Borrowing Base at any time, then the Borrower shall (A) prepay the
Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess
remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the
Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as
cash collateral as provided in Section 2.08(j).  

     (v)     Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied,
first, ratably to any Canadian Prime Borrowings and U.S.  Prime Borrowings then outstanding,
and, second, to any CDOR Borrowings and Eurodollar Borrowings then outstanding, and if more
than one CDOR Borrowing or Eurodollar Borrowing is then outstanding, to each such CDOR
Borrowing or Eurodollar Borrowing in order of priority beginning with the CDOR Borrowing or
Eurodollar Borrowing with the highest interest rate applicable thereto and ending with the
CDOR Borrowing or Eurodollar Borrowing with the lowest interest rate applicable thereto.  

     (vi)     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 (other than a Defaulting Lender to the extent set forth in Section 2.10) a
commitment fee, which shall accrue at the applicable Commitment Fee Rate on the average daily
amount of the unused Commitment of such Lender during the period from and including the Effective
Date to but excluding the Termination Date.  Accrued commitment fees shall be payable in arrears on
the third Business Day following 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 Effective Date.  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 (other than a Defaulting Lender to the extent set forth in Section
2.10) 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 which has been funded by such Lender) during the
period from and including the Effective Date 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 each Issuing Bank a fronting fee, which shall accrue at the rate per annum agreed to with
such Issuing Bank on the average daily amount of that portion of the LC Exposure attributable to
such Issuing Bank (excluding any portion thereof attributable to unreimbursed LC Disbursements)
during the period from and including the Effective Date to but

49

 

excluding the later of the date of
termination of the Commitments and the date on which there ceases to be any LC Exposure
attributable to such Issuing Bank, provided that (x) if the expiration date of the Letter of Credit
is less than one year after its date of issuance and the aggregate fronting fee otherwise payable
through its expiration would be less than C$500, then the Borrower shall pay to such Issuing Bank
C$500 upon the issuance of such Letter of Credit in lieu of the fronting fee otherwise payable and
(y) no fronting fee shall be payable with respect to any Grandfathered Letters of Credit on the
Effective Date or thereafter, until and unless such Grandfathered Letter of Credit is extended,
renewed or reissued hereunder, and (iii) to each Issuing Bank, for its own account, its standard
fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or
processing of drawings thereunder.  Participation fees and fronting fees accrued through and
including the last day of March, June, September and December of each year shall be payable in
arrears on the third Business Day following such last day,
commencing on the first such date to occur after the Effective Date; 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 an Issuing Bank pursuant to this Section
3.05(b) shall be payable within 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 4

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 3:00 p.m.,
Toronto time, on the date when due (for purposes of computing interest and fees, each such payment
made after such time on such due date to be deemed to have been made on the next succeeding
Business Day), 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, absent manifest error.  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 an 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 the Agreed Currency.  

     (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

50

 

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.  

     (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 resulting in such Lender receiving payment
of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements
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; 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 to any assignee or Participant, other than to any
Credit Party 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 such 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 such 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 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 hereunder, pursuant to Section 2.05(a), Section
2.08(d), Section 2.08(e) or Section 4.02 or otherwise, 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 other Guarantors unto and in favor of the Administrative Agent for the
benefit of the Secured Parties of all of the Borrower’s or each other Guarantor’s interest in and
to production and all proceeds attributable thereto which may be produced from or allocated to the
Mortgaged Property.  The Security Instruments further provide in general for the application of
such proceeds to the satisfaction of

51

 

the Secured Indebtedness and other obligations described
therein and secured thereby.  Notwithstanding
anything to the contrary contained in the 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 production from or allocated to the Mortgaged Property nor take any
other action to cause the proceeds thereof to be remitted to the Administrative Agent or the
Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower or such other
Credit Party 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 other Credit Party.  

ARTICLE 5

Increased Costs; Break Funding Payments; Payments; Taxes; Illegality

     Section 5.01   Increased Costs.  

     (a)     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; or

     (ii)     impose on any Lender or the London interbank market any other condition affecting
this Agreement, CDOR Loans made by such Lender 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 CDOR Loan or 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, but not including Excluded Taxes), 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.  

     (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 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.  

     (c)     Certificates.  A certificate of a Lender or any 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 30 days after
receipt thereof.  

52

 

     (d)     Effect of Failure or Delay in Requesting Compensation.  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;
provided that the
Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to this
Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date
that such Lender or such Issuing Bank, as the case may be, notifies the Borrower of the Change in
Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s
intention to claim compensation therefor; provided further that, if the Change in Law giving rise
to such increased costs or reductions is retroactive, then the 180-day period referred to above
shall be extended to include the period of retroactive effect thereof.  

     Section 5.02   Break Funding Payments.  In the event of (a) the payment (including
prepayment) of any principal of any CDOR Loan or 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 CDOR Loan or any Eurodollar Loan into a Canadian Prime Loan or a U.S.  Prime Loan
other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow as
a result of a failure to satisfy the conditions set forth in Section 6.02, any CDOR Loan or any
Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the
assignment of any CDOR Loan or 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(a),
then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event (exclusive of any lost profits or opportunity costs or processing or
other related fees).  In the case of a CDOR 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 (A) the amount
of interest which would have accrued on the principal amount of such Loan had such event not
occurred, at the CDOR 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 (B) 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 Canadian Dollar deposits of a comparable amount and period from other banks in the
CDOR market.  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 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 10 Business 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 any Credit Party under any Loan Document shall be made free and clear of and without deduction
for any Indemnified Taxes or Other Taxes; provided that if any Credit Party shall be required to
deduct any

53

 

Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be
increased, as a payment of additional interest, 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) such Credit Party shall make such deductions and (iii)
such Credit Party 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 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; provided that the Borrower shall not be required to indemnify the Administrative Agent,
any Lender or any Issuing Bank for any amounts under this Section 5.03(c) to the extent that such
Person fails to notify the Borrower of its intent to make a claim for indemnification under this
Section 5.03(c) within 180 days after a claim is asserted against such Person 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, together with, to the extent
available, reasonable supporting documentation relating to such payment or liability, 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 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)     Each Lender shall severally indemnify the Administrative Agent, within 10 days after
demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent
that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes
and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such
Lender’s failure to comply with the provisions of Section 12.04(c) relating to the maintenance of a
Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that
are payable or paid by the Administrative Agent in connection with any Loan Document, and any
reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were
correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate as
to the amount of such payment or liability delivered to any Lender by the Administrative Agent
shall be conclusive absent manifest error.  Each Lender hereby authorizes the Administrative Agent
to set off and apply any and all amounts at any time owing to such Lender under any Loan Document
or otherwise payable by the Administrative Agent to the Lender from any other source against any
amount due to the Administrative Agent under this paragraph (e).  

     (f)     Tax Refunds.  If the Administrative Agent or a Lender determines, in its sole
discretion, that it has received a refund of any Indemnified Taxes or Other Taxes as to which it
has been indemnified

54

 

by the Borrower or with respect to which the Borrower has paid additional
amounts pursuant to 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 Section 5.03
with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket 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(f) 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.  

     (g)     Tax Certifications.  The Administrative Agent, each Lender and each Issuing Bank
agrees to provide, upon reasonable request, the Administrative Agent and any Credit Party with (i)
any forms or certifications reasonably necessary for the Administrative Agent or such Credit Party
to determine the applicable rate of any withholding tax, including, if applicable, the availability
of a reduced rate pursuant to an applicable tax treaty and (ii) any other information or documents
reasonably requested in connection with such Lender’s or such Issuing Bank’s status as a Foreign
Lender (or as a Lender that is not a Foreign Lender).  

     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 solely as a result of such designation or
assignment.  

     (b)     Replacement of Lenders.  If (i) any Lender requests compensation under Section
5.01, or (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, or (iii) any Lender
is a Defaulting Lender, or (iv) any Lender has asserted that any adoption or change of the type
described in Section 5.05 has occurred, or (v) any Lender fails to approve an amendment, waiver or
other modification to this Agreement and at least the Required Lenders have approved such
amendment, waiver or other modification, or (vi) any Lender fails to approve an increase of the
Borrowing Base and at least the Required Lenders have approved such increase, 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 (A) assume such obligations and (B) in the case of clauses (v)
and (vi), consent to such amendment, waiver, modification, increase, decrease or reaffirmation
(which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) if
such assignee is not a Lender, the Borrower shall have received the prior written consent of the
Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans and participations in
LC Disbursements, accrued

55

 

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) and (iii) in the case of any such
assignment resulting from a claim for compensation under Section 5.01 or payments required to be
made pursuant to Section 5.03, such assignment will result in a reduction in such compensation or
payments.  A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease
to apply.  

     Section 5.05   Illegality.  Notwithstanding any other provision of this Agreement:

     (a)     In the event that it becomes unlawful for any Lender or its applicable lending office to
honor its obligation to make or maintain CDOR Loans or Eurodollar Loans either generally or having
a particular Interest Period hereunder, then (i) such Lender shall promptly notify the Borrower and
the Administrative Agent thereof and such Lender’s obligation to make such CDOR Loans or Eurodollar
Loans, as applicable, shall be suspended (the “Affected Loans”) until such time as such
Lender may again make and maintain such CDOR Loans or Eurodollar Loans, as applicable, and (ii) all
Affected Loans which would otherwise be made by such Lender shall be made instead as Canadian Prime
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 Canadian Prime
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) Canadian Prime Loans, all payments of principal which would
otherwise be applied to such Lender’s Affected Loans shall be applied instead to its Canadian Prime
Loans; and

     (b)     If it becomes unlawful for any Lender or its applicable lending office to honor its
obligation to make any Loans to the Borrower, then such Lender shall promptly notify the Borrower
and the Administrative Agent thereof and such Lender’s obligation to make Loans shall be suspended
until such time as such Lender may again make and maintain Loans to the Borrower.  The Borrower
shall have no obligation to pay to such Lender the commitment fee described in Section 3.05(a) that
would otherwise accrue during such period of suspension.

and is qualified to do business in, and is in good standing in, every jurisdiction where such

Party’s corporate, partnership or limited liability company powers and have been duly authorized by
all necessary corporate, partnership or limited liability company and, if required, stockholder,

executed and delivered by such Credit Party and constitutes a legal, valid and binding obligation
of such Credit Party, as

59

 

applicable, enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, fraudulent transfer or conveyance, moratorium or
other laws affecting creditors’ rights generally and subject to general principles of equity,

have a Material Adverse Effect:

     (a)     neither any Oil and Gas Property of any Credit Party nor the operations conducted by any

environment; and

     (f)     to the Borrower’s knowledge, no Credit Party has any contingent liability under

(including, to the extent applicable to them, FCPA and OFAC) and all agreements and other
instruments binding upon it or its Oil and Gas Properties, and possesses all licenses, permits,
franchises, exemptions, approvals and other governmental authorizations necessary for the ownership
of its Oil and Gas Properties and the conduct of its business, except where the failure to do so,
individually or in the aggregate, would not reasonably be expected to result in a Material Adverse
Effect.

all Tax returns and reports required to have been filed (or obtained extensions with respect
thereto) and has paid or caused to be paid all Taxes and all remittances required to have been paid

which the applicable Credit Party has set aside on its books adequate reserves in accordance with
GAAP or (b) to the extent that the failure to do so would not reasonably be expected to result in a
Material Adverse Effect.  No action to enforce any Tax Lien has been commenced.  

61

 

     Section 7.09   Disclosure; No Material Misstatements.  Taken as a whole, none of the
reports, financial statements, certificates or other written information (other than projections)
furnished by or on behalf of any Credit Party 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

information so furnished), when
furnished (and, with respect to any such information delivered to the Administrative Agent or
any Lender or any of their Affiliates prior to the Effective Date, on the Effective Date), contains
any material misstatement of fact or omits to state any material fact necessary to make the

provided that, with respect to projected financial information, prospect information, geological
and geophysical data and engineering projections, the Borrower represents only that such
information was prepared in good faith based upon assumptions believed to be reasonable at the
time, recognizing that (a) there are industry-wide risks normally associated with the types of
business conducted by the Credit Parties and (b) projections concerning volumes attributable to the
Oil and Gas Properties of the Credit Parties and production and cost estimates contained in each

the Credit Parties do not warrant that such opinions, estimates and projections will ultimately
prove to have been accurate.

Effect and provided that no representation or warranty is made with respect to any Oil and Gas
Property or interest to which no proved oil or gas reserves are properly attributed:

     (a)     Each of the Credit Parties has good and defensible title to the material Oil and Gas
Properties evaluated in the Reserve Report used in the most recent determination of the Borrowing
Base and good title to all its personal Properties that are necessary to permit the Credit Parties
to conduct their business in all material respects in the same manner as its business has been
conducted prior to the date hereof, in each case, subject to Immaterial Title Deficiencies and free
and clear of all Liens except Liens permitted by Section 9.03 (subject to the penultimate

62

 

sentence
thereof).  Subject to Immaterial Title Deficiencies and after giving full effect to Liens permitted
by Section 9.03 (subject to the penultimate sentence thereof), the Credit Party specified as the
owner owns the net interests in production attributable to the Hydrocarbon Interests as reflected
in the most recently delivered Reserve Report.  The ownership of such Oil and Gas Properties shall
not obligate such Credit Party to bear the costs and expenses relating to the maintenance,
development and operations of each such Oil and Gas Property in an amount materially in excess of
the working interest of each Oil and Gas Property set forth in the most recently delivered Reserve
Report that is not offset by a corresponding proportionate increase in such Credit Party’s net
revenue interest in such Oil and Gas Property; provided that any applicable Credit Party shall
have the right or obligation to bear costs disproportionate to such Credit Party’s working interest
with respect to any Hydrocarbon Interest for a period of time in order to earn, or in connection
with the acquisition of, an interest in such Hydrocarbon Interest as evidenced by written
agreement.  

     (b)     All material leases and agreements necessary for the conduct of the business of the Credit
Parties are valid and subsisting, in full force and effect, and there exists no default or event or
circumstance which with the giving of notice or the passage of time or both would give rise to a
default under any such lease or leases.  

     (c)     The rights and Properties presently owned, leased or licensed by the Credit Parties,
including, without limitation, all easements and rights of way, include all rights and Properties
necessary to permit the Credit Parties to conduct their business in the same manner as its business
has been conducted prior to the date hereof.  

     (d)     Each Credit Party owns, or is licensed to use, (i) all trademarks, tradenames, copyrights,
patents and other intellectual Property material to its business, and the use thereof by each such
Credit Party does not infringe upon the rights of any other Person and (ii) all databases,
geological data, geophysical data, engineering data, seismic data, maps, interpretations and other
technical information the use of which is material to 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.  

     Section 7.14   Compliance with Benefit Plans; ERISA.  Except as could not reasonably be
expected to have a Material Adverse Effect, (a) the Canadian Pension Plans, if any, are duly
registered under the Income Tax Act (Canada) and all applicable provincial or federal pension
benefits standards legislation and no event has occurred which is reasonably likely to cause the
loss of such registered status; (b) all obligations of the Credit Parties (including any applicable
fiduciary, funding, investment and administration obligations) required to be performed in
connection with the Canadian Pension Plans, if any, have been performed in accordance with
applicable laws and regulations; (c) no promises of benefit improvements under the Canadian Pension
Plans, if any, or the Canadian Benefit Plans have been made; (d) all reports and disclosures
relating to the Canadian Pension Plans and Canadian Benefit Plans required by any applicable laws
or regulations have been filed or distributed in accordance with applicable laws and regulations;
(e) no Credit Party has made any improper withdrawals prohibited by applicable law, or applications
of, the assets of any of the Canadian Pension Plans; (f) no Canadian Pension Plan Termination Event
has occurred; (g) no Credit Party has any knowledge that the Canadian Pension Plans, if any, are
the subject of an investigation, any other proceeding, an action or a claim other than a routine
claim for benefits; (h) all contributions or premiums required to be made by any Credit Party to
the Canadian Pension Plans and the Canadian Benefit Plans have been made within the time limits
required by, and in accordance with, the terms of such plans and applicable laws and regulations;
and (i) all employee contributions to the Canadian Pension Plans, if any, required to be made by
way of authorized payroll deduction have been properly withheld and fully paid into such plans
within the time limits required by, and in accordance with, the terms of such plans and applicable
laws and regulations.  No Credit Party contributes or has made contributions on behalf of its
employees to a multi-employer pension

63

 

plan, as such term is defined under applicable Canadian
provincial or federal pension benefits standards legislation.  No Canadian Pension Plan has an
Unfunded Current Liability that would, individually or when taken together with any other
liabilities referenced in this Section 7.14, reasonably be anticipated to have a Material Adverse
Effect.  There has been no failure to administer or operate the Foreign Plans in accordance with
the terms thereof except for any failure to so administer or operate the Foreign Plans as could not
reasonably be expected to have a Material Adverse Effect.  As of the date hereof, neither the
Borrower nor any Subsidiary nor any ERISA Affiliate of the Borrower or any Subsidiary maintains
sponsors, or contributes to (or has at any time in the six-year period preceding the date
hereof, maintained, sponsored, or contributed to) any Pension Plan or Multiemployer Plan.  Except
in such instances where an action, omission or failure would not reasonably be expected to have a
Material Adverse Effect, each Plan maintained by any Credit Party or any ERISA Affiliate of any
Credit Party is in compliance with the terms of such Plan and the applicable provisions of ERISA
and the Code with respect to each Plan.  No ERISA Event has occurred or is reasonably expected to
occur that, when taken together with all other such ERISA Events for which liability is reasonably
expected to occur, would reasonably be expected to result in a Material Adverse Effect.  Except in
such instances where an action, omission or failure would not reasonably be expected to have a
Material Adverse Effect, (i) each Plan that is intended to be “qualified” within the meaning of
Section 401(a) of the Code is, and has been during the period from its adoption to date, so
qualified, both as to form and operation, and all necessary governmental approvals, including a
favorable determination as to the qualification under the Code of such Plan and each amendment
thereto, have been or will be timely obtained, and (ii) the actuarial present value of the benefit
liabilities (within the meaning of section 4041 of ERISA) under each Plan which is subject to Title
IV of ERISA does not, as of the end of the 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.  Neither any Credit Party nor any ERISA Affiliate
of any Credit Party maintains or contributes to any Plan that provides a post-employment health
benefit, other than a benefit required under Section 601 of ERISA, or maintains or contributes to a
Plan that provides health benefits that is not fully funded except where the failure to fully fund
such Plan would not reasonably be expected to have a Material Adverse Effect.  As of the date
hereof, neither the Borrower nor any Restricted Subsidiary nor any ERISA Affiliate of the Borrower
or any Restricted Subsidiary maintains a multiple employer welfare benefit arrangement within the
meaning of Section 3(40)(A) of ERISA.  

     Section 7.15   Solvency.  After giving effect to the transactions contemplated hereby,
(a) the aggregate assets (after giving effect to amounts that could reasonably be received by
reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the
Credit Parties, taken as a whole, will exceed the aggregate Debt of the Credit Parties on a
consolidated basis, as the Debt becomes absolute and matures, (b) each of the Credit Parties will
not have incurred Debt beyond its ability to pay such Debt (after taking into account the timing
and amounts of cash to be received by each of the Credit Parties and the amounts to be payable on
or in respect of its liabilities, and giving effect to amounts that could reasonably be received by
reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute
and matures and (c) each of the Credit Parties will not have unreasonably small capital for the
conduct of its business.  

     Section 7.16   Priority; Security Matters.  The Secured Indebtedness is and shall be at
all times secured by valid, perfected first priority Liens (taken by way of a floating charge over
real property or otherwise) in favor of the Administrative Agent, covering and encumbering the
Mortgaged Properties and other Properties pledged pursuant to the Security Instruments, to the
extent perfection has occurred or will occur, by the recording of a debenture or mortgage, the
filing of a PPSA or UCC financing statement or by possession (in each case, to the extent available
in the applicable jurisdiction); provided, that the priority of the Liens in favor of the
Administrative Agent may be subject to Permitted Liens.

previously disclosed to the Lenders) that, in either case, if adversely determined, would
reasonably be expected to result in a Material Adverse Effect; and

     (c)     the filing or commencement of any action, suit, proceeding, investigation or arbitration
by or before any arbitrator or Governmental Authority involving or relating to the Loan Documents.

franchises material to the conduct of its business and maintain, if necessary, its qualification to
do business in each other jurisdiction in which its Oil and Gas Properties are located or the
ownership of such Properties requires such qualification, except where the failure to so qualify
would not reasonably be expected to have a Material Adverse Effect; provided that the foregoing
shall not prohibit any merger, consolidation, liquidation or dissolution permitted under Section
9.09.  

     Section 8.04   Payment of Obligations.  The Borrower will, and will cause each other
Credit Party to, pay its obligations, including Tax liabilities and remittance liabilities of the
Credit Parties, before the same shall become delinquent or in default, except where (i) (A) the
validity or amount thereof is being contested in good faith by appropriate proceedings, and (B)
such Credit Party has set aside on its books adequate reserves with respect thereto in accordance
with GAAP or (ii) the failure to make payment would not reasonably be expected to result in a
Material Adverse Effect or result in the seizure or levy of any Oil and Gas Property of any Credit
Party that was evaluated in the Reserve Report used in the most recent determination of the
Borrowing Base.  

     Section 8.05   Operation and Maintenance of Properties.  The Borrower will and will
cause each other Credit Party to, in all material respects: (a) promptly pay and discharge, or make
reasonable efforts to cause to be paid and discharged, when due all delay rentals, royalties and
expenses accruing under the leases or other agreements affecting or pertaining to its material Oil
and Gas Properties evaluated in the Reserve Report used in the most recent determination of the
Borrowing Base, provided that, in the case of delay rentals, the Borrower and/or the applicable
Credit Party shall only be required to pay and discharge, or make reasonable efforts to pay and
discharge, delay rentals as and to the extent the Borrower or such other Credit Party determines in
good faith that payment and discharge thereof is in the Borrower’s or such other Credit Party’s, as
applicable, best interest, (b) perform, or make reasonable and customary efforts to cause to be
performed, the obligations of the Borrower or any such other Credit Party required by each and all
of the assignments, deeds, leases, subleases, contracts and agreements affecting its interests in
its material Oil and Gas Properties evaluated in the Reserve Report used in the most recent
determination of the Borrowing Base, (c) do all other things necessary to keep unimpaired, except
for Liens permitted by the Loan Documents, its rights with respect to its material Oil and Gas
Properties evaluated in the Reserve Report used in the most recent determination of the Borrowing
Base and prevent any forfeiture thereof or a default thereunder, (d) keep and maintain all Oil and
Gas Property material to the conduct of its business in good working order and condition, ordinary
wear and tear excepted and (e) to the extent the Borrower is not the operator of any Property, the
Borrower shall use reasonable efforts to cause the operator to comply with this Section 8.05,
except (x) to the extent a portion of such Oil and Gas Properties is no longer capable of producing
Hydrocarbons in economically reasonable amounts, (y) for dispositions permitted by this Agreement
or (z) when the failure to do so would not, in the aggregate, reasonably be expected to have a
Material Adverse Effect.  

     Section 8.06   Insurance.  The Borrower will, and will cause each other Credit Party to,
maintain, with financially sound and reputable insurance companies, insurance in such amounts and
against such risks as are customarily maintained by companies engaged in the same or similar
businesses operating in the same or similar locations.  The loss payable clauses or provisions in
said insurance policy or policies insuring any of the collateral for the Loans shall be endorsed in
favor of the Administrative

68

 

Agent as its interests in the collateral may appear and such policies
shall name the Administrative Agent and the Lenders as “additional insureds” and provide that the
insurer will endeavor to give at least 30 days prior notice of any cancellation to the
Administrative Agent.  

     Section 8.07   Books and Records; Inspection Rights.  The Borrower will, and will cause
each other Credit Party 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 other Credit Party to, permit any representatives designated by
the Administrative Agent or any Lender (coordinated through and together with the Administrative
Agent), upon reasonable prior notice, to visit and inspect its Oil and Gas 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 during the Borrower’s
or such other Credit Party’s normal business hours (and in a manner so as to the extent
practicable, not to unreasonably interfere with the normal business operations
of the Borrower or such other Credit Party) not more than one (1) time per fiscal year;
provided, that to the extent an Event of Default then exists, as often as reasonably requested.  The Lenders shall bear the cost of such inspections and examinations unless an Event of Default
then exists, in which event the Borrower shall bear such cost.  

     Section 8.08   Compliance with Laws.  The Borrower will, and will cause each other
Credit Party to, comply with all Governmental Requirements applicable to it or its Oil and Gas
Properties, except where the failure to do so, individually or in the aggregate, would not
reasonably be expected to result in a Material Adverse Effect.  

     Section 8.09   Environmental Matters.  (a) Except to the extent that the failure to do
so would not reasonably be expected to have a Material Adverse Effect, (i) the Borrower shall, and
shall cause each other Credit Party to, comply with all applicable Environmental Laws, including,
without limitation, (x) all licensing, permitting, notification, and similar requirements of
Environmental Laws, and (y) all provisions of Environmental Laws regarding storage, discharge,
release, transportation, treatment and disposal of Hazardous Materials and (ii) the Borrower shall,
and shall cause each other Credit Party to, promptly pay and discharge when due all claims,
liabilities and obligations with respect to any clean-up or remediation measures necessary to
comply with applicable Environmental Laws, provided that such payment or discharge shall not be
required to the extent that (A) the amount, applicability or validity thereof is being contested in
good faith by appropriate proceedings promptly initiated and diligently conducted and (B) Borrower
or such other Credit Party, as and to the extent required in accordance with GAAP, shall have set
aside on its books reserves (segregated to the extent required by GAAP) deemed by them to be
adequate with respect thereto.  

     (b)     To the extent the Borrower or another Credit Party is not the operator of any Property,
none of the Credit Parties shall be obligated to directly perform any undertakings contemplated by
the covenants and agreements contained in this Section 8.09 which are performable only by such
operators or are beyond the control of the Credit Parties.  Notwithstanding the above and except to
the extent that the failure to do so would not reasonably be expected to have a Material Adverse
Effect, the Borrower shall be obligated to enforce such operators’ contractual obligations to
maintain, develop and operate the Oil and Gas Properties subject to such operating agreements, and
the Borrower shall, and shall cause the other Credit Parties to, use commercially reasonable
efforts to cause the operator to comply with this Section 8.09.  

     (c)     To the extent reasonably requested by the Administrative Agent, the Borrower will, and
will cause each other Credit Party to, provide environmental assessment, audit or test reports of
any Oil and Gas Properties of the Borrower or any other Credit Party, provided an Event of Default
then exists or

69

 

the Administrative Agent has a reasonable suspicion that either an Event of Default
or a breach of any representation or warranty set forth in Section 7.06 hereof then exists.  

     (d)     In connection with any acquisition by Borrower or any other Credit Party of any Oil and
Gas Property for consideration of at least C$17,500,000, other than an acquisition of additional
interests in Oil and Gas Properties in which any Credit Party previously held an interest, to the
extent Borrower or such other Credit Party obtains or is provided with the same, the Borrower
shall, promptly following Borrower’s or such other Credit Party’s obtaining or being provided with
the same, deliver to the Administrative Agent such final and non-privileged material environmental
reports of such Oil and Gas Properties as are reasonably requested by the Administrative Agent.  

     Section 8.10   Further Assurances.  (a) The Borrower at its sole expense will, and will
cause each other Credit Party 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 other Credit Party, 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
Indebtedness, or to correct any omissions in this Agreement or 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, or any equivalent thereto in Canada or any
province thereof relative to all or any part of the Mortgaged Property without the signature of the
Borrower or any other Guarantor where permitted by law.  A carbon, photographic or other
reproduction of the Security Instruments or any financing statement covering the Mortgaged Property
or any part thereof shall be sufficient as a financing statement where permitted by law.  

     Section 8.11   Reserve Reports.  (a) On or before May 1, 2012 and April 1st of each year
thereafter, the Borrower shall furnish to the Administrative Agent a Reserve Report prepared by one
or more Approved Petroleum Engineers (the “Prepared Reserve Report”) as of January
1st of such year.  On or before October 1st of each year, commencing October 1, 2012,
the Borrower shall furnish to the Administrative Agent and the Lenders a Reserve Report as of July
1st of such year prepared by or under the supervision of the chief engineer of the
Borrower in accordance with the procedures used in the most recent Prepared Reserve Report.  It is
understood that projections concerning volumes attributable to the Oil and Gas Properties and
production and cost estimates contained in each Reserve Report are necessarily based upon
professional opinions, estimates and projections and that the Credit Parties do not warrant that
such opinions, estimates and projections will ultimately prove to have been accurate.  

     (b)     In the event of an Interim Redetermination requested by the Administrative Agent or the
Borrower pursuant to Section 2.07(b), the Borrower shall, upon the request of the Administrative
Agent, furnish to the Administrative Agent and the Lenders a Reserve Report (i) prepared by or
under the supervision of the chief engineer of the Borrower and in accordance with the procedures
used in the immediately preceding Prepared Reserve Report delivered pursuant to Section 8.11(a),
and (ii) which shall have an “as of” date as required by the Administrative Agent, no later than a
date mutually agreed to by the Borrower and the Administrative Agent.  If the Administrative Agent
does not request an updated Reserve Report pursuant to the immediately preceding sentence, the
Administrative Agent and the

Lenders may base such Interim Redetermination on the Reserve Report
most recently delivered by the Borrower hereunder.  

     (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, (ii) subject to Immaterial Title Deficiencies, the
Borrower or a Guarantor owns good and defensible title to the Oil and Gas Properties evaluated in
such Reserve Report and such Properties are free of all Liens except for Permitted Liens and Liens
securing the Secured Indebtedness, (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 one half bcf
of gas in the aggregate with respect to its Oil and Gas Properties evaluated in such Reserve Report
which would require the Borrower or any Guarantor to deliver Hydrocarbons either generally or
produced from such Oil and Gas Properties at some future time without then or thereafter receiving
full payment therefor, (iv) 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 pertain to the sale of production at a fixed price and have a
maturity date of longer than six (6) months from the date of such certificate and (v) a true and
complete list of all Oil and Gas Swap Agreements of the Borrower and each other Credit Party is
included, which list contains the material terms thereof (including the type, remaining term,
counterparty, mark-to-market value as of the end of the second month immediately preceding the date
of such certificate and notional amounts or volumes), any credit support agreements relating
thereto, any margin required or supplied under any credit support document, and the counterparty to
each such agreement.  

     (d)     The Reserve Reports may only include Oil and Gas Properties that are (x) located in
British Columbia, Canada, Alberta, Canada, or another province in Canada that at such time allows
for a secured lender to receive the benefit of a floating charge over real property located in such
province, and for which such floating charge is created by a debenture or other Security Instrument
and is of record (as necessary) as contemplated under Section 6.01(f)(i) or (y) located in any
other province in Canada, the United States or any other country or jurisdiction reasonably
acceptable to the Administrative Agent; provided that with respect to Oil and Gas Properties set
forth in this clause (y), (i) the Administrative Agent shall be reasonably satisfied that fixed
charges, collateral agreements or other Security Instruments create first priority, perfected Liens
(subject only to Permitted Liens) on at least 80% of the total value of the Proved Hydrocarbon
Interests relating to such Oil and Gas Properties (including any such Oil and Gas Properties
subject to floating charges) and (ii) the Administrative Agent shall have received title
information as the Administrative Agent may reasonably require satisfactory to the Administrative
Agent setting forth the status of title to at least 75% of the total value of such Oil and Gas
Properties; provided, that with respect to such Oil and Gas Properties referred to in the foregoing
clauses (x) and (y), the Administrative Agent shall have received such other closing documents,

reasonably satisfactory to, the Administrative Agent.

left blank].

     Section 8.13   Additional
Collateral; Additional Guarantors.  (a) [Reserved].  

     (b)     If the Borrower or any other Credit Party becomes the owner of a Restricted Subsidiary,
then the Borrower shall, or shall cause such other Credit Party to, promptly, but in any event no
later than 30 days after the date of becoming an owner thereof (or such longer period as the
Administrative Agent may agree in its discretion), (i) pledge 100% of the Equity Interests of such
new Restricted Subsidiary (including, without limitation, delivery of original stock certificates
evidencing the Equity Interests of

71

 

such new Restricted Subsidiary, together with appropriate
undated stock powers for each certificate duly executed in blank by the registered owner thereof)
and (ii) execute and deliver such other additional closing documents, certificates and legal
opinions as shall reasonably be requested by the Administrative Agent.  If any Person other than
QRI (or, from and after the New Parent Joinder, New Parent) at any time acquires or otherwise
possesses any of the Equity Interests issued by the Borrower (including an Intermediate HoldCo),
the Borrower shall cause each such Person to promptly, but in any event no later than 30 days after
the date of becoming an owner thereof (or such longer period as the Administrative Agent may agree
in its discretion), (i) pledge 100% of the Equity Interests in the Borrower owned by such person
pursuant to a Pledge Agreement (including, without limitation, delivery of original stock
certificates evidencing the Equity Interests of the Borrower, together with an appropriate undated
stock power for each certificate duly executed in blank by the registered owner thereof) and (ii)
execute and deliver such other additional closing documents, certificates, and legal opinions as
shall reasonably be requested by the Administrative Agent.  

     (c)     The Borrower shall cause the following Persons to guarantee the Secured Indebtedness
pursuant to the Guaranty Agreement:

     (i)     each Material Restricted Subsidiary;

     (ii)     any Person required to guarantee the Secured Indebtedness in order for the Borrower
to be in compliance with Section 9.05(b);

     (iii)     any Person that guarantees any Permitted Additional Debt;

     (iv)     any Restricted Subsidiary that places a Lien on its Oil and Gas Properties to
secure the Secured Indebtedness;

     (v)     one or more additional Restricted Subsidiaries to the extent necessary to cause (A)
the total assets of the Restricted Subsidiaries that are not Guarantors to be less than 15%
of the combined assets of the Credit Parties and (B) the combined EBITDAX of such Restricted
Subsidiaries to be less than 15% of the combined EBITDAX of the Credit Parties; and

     (vi)     each Intermediate HoldCo, New Parent and, following the occurrence of a Qualified
IPO, any subsequent direct owner of Equity Interests in the Borrower.  

     (d)     In connection with any guaranty required by Section 8.13(c), the Borrower shall, or shall
cause such Subsidiary or other Person to promptly, but in any event no later than 30 days (or such
longer period as the Administrative Agent may agree in its discretion) after the event requiring
such guaranty, execute and deliver (i) a supplement to the Guaranty Agreement and (ii) such other
additional closing documents, certificates and legal opinions as shall reasonably be requested by
the Administrative Agent.  If at any time any Person is not otherwise required to guarantee the
Secured Indebtedness hereunder (whether pursuant to the other provisions of this Section 8.13 or
otherwise) or under any other Loan Document, then upon receipt by the Administrative Agent of
evidence satisfactory to it that such Person has been fully and finally released from its guarantee
obligations in respect of any Permitted Additional Debt, such Person shall be released from its
guarantee obligations with respect to the Secured Indebtedness and the Administrative Agent shall,
at the sole cost and expense of the Borrower, execute such further documents and do all such
further acts so as to reasonably evidence such release.  

     (e)     If a Default or Event of Default has occurred and is continuing and the Majority Lenders
consider it necessary for their adequate protection, the Borrower, at the request of the
Administrative

72

 

Agent, will forthwith grant or cause to be granted to the Administrative Agent for
the benefit of the Secured Parties, a fixed Lien (subject only to Permitted Liens) in such of the
applicable Credit Party’s property as the Administrative Agent, in its sole discretion, determines
as security for all then present and future Secured Indebtedness of the Credit Parties to the
Secured Parties.  In this connection, the Borrower will, and will cause each other Credit Party to:

     (i)     provide the Administrative Agent with such information as is reasonably required by
the Administrative Agent to identify the property to be charged pursuant to this Section
8.13(e);

     (ii)     do all such things as are reasonably required to grant, or cause such Credit Party
to grant, in favor of the Agent, the Secured Parties, a fixed Lien (subject only to Permitted
Liens) in respect of such property to be so charged pursuant to this Section 8.13(e);

     (iii)     provide the Administrative Agent with all corporate or partnership resolutions and
other action, as reasonably required, for any Credit Party to grant the fixed Lien (subject
only to Permitted Liens) in the property identified by the Administrative Agent to be so
charged;

     (iv)     provide the Administrative Agent with such security instruments and other documents
which the Administrative Agent, acting reasonably, deems are necessary to give full force and
effect to the provisions of this Section 8.13(e);

and instruments in such public registry offices in Canada or any province thereof or any
other jurisdiction as the Administrative Agent, acting reasonably, deems necessary to give

     (vi)     pay all reasonable costs and expenses incurred by the Administrative Agent in
connection with the preparation, execution and registration of all agreements, documents and
instruments made in connection with this Section 8.13(e).

the Administrative Agent immediately upon becoming aware of the occurrence of any ERISA Event or
Canadian Pension Plan Termination Event that alone or together with any other ERISA Events or
Canadian Pension Plan Termination Events that have occurred, would reasonably be expected to result
in liability of any Credit Party or any ERISA Affiliates in an aggregate amount which would
reasonably be expected to have a Material Adverse Effect, a written notice signed by a Responsible
Officer, specifying the nature thereof, what action the applicable Credit Party or any 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, the PBGC or any equivalent
agency or authority with jurisdiction over Canadian Pension Plans with respect thereto.  With
respect to each Pension Plan, the Borrower will, and will cause each other Credit Party and ERISA
Affiliate to, (a) satisfy in full and in a timely manner, without incurring any late payment or
underpayment charge or penalty that would reasonably be expected to have a Material Adverse Effect
and without giving rise to any Lien securing an amount in excess of C$15,000,000, 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 (b) pay, or cause to be paid, to the PBGC in a timely
manner, without incurring any late payment or underpayment charge or penalty that would reasonably
be expected to have a Material Adverse Effect, all premiums required pursuant to sections 4006 and

permit any other Credit Party to terminate, any Canadian Pension Plan in a manner, or take

73

 

any
other action with respect to any Canadian Pension Plan, which would reasonably be expected to have
a Material Adverse Effect, (ii) fail to make, or permit any other Credit Party to fail to make,
full payment when due of all amounts which, under the provisions of any Canadian Pension Plan,
agreement relating thereto or applicable law, the Borrower or any other Credit Party is required to
pay as contributions thereto, except where the failure to make such payments could not reasonably
be expected to have a Material Adverse Effect, or (iii) permit to exist, or allow any other Credit
Party to permit to exist, any Unfunded Current Liability, whether or not waived, with respect to
any Canadian Pension Plan in an amount which would reasonably be expected to cause a Material
Adverse Effect.  

     Section 8.15   Unrestricted Subsidiaries.  The Borrower (or, from and after the New
Parent Joinder, New Parent):

     (a)     will cause the management, business and affairs of each of the Borrower (or, from and
after the New Parent Joinder, New Parent) 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 (or, from and after the New Parent Joinder, New
Parent) and its respective 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 the Borrower (or, from and after
the New Parent Joinder, New Parent) 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 Debt of any of the Unrestricted Subsidiaries; and

     (c)     will not permit any Unrestricted Subsidiary to hold any Equity Interest in, or any Debt
of, the Borrower or any other Credit Party.  

     Section 8.16   Section 1031 Exchange.  If the Borrower elects to participate in a
Section 1031 Exchange with respect to any Oil and Gas Properties, then on or before 180 days
following the acquisition by the Section 1031 Counterparty of such Oil and Gas Properties from the
Borrower, the Borrower shall receive from the Section 1031 Counterparty (a) Oil and Gas Properties
having a substantially equivalent value to the Oil and Gas Properties that the Section 1031
Counterparty acquired from the Borrower, (b) payment in full in cash of the note given by the
Section 1031 Counterparty to the Borrower or (c) any combination of Oil and Gas Properties and a
partial cash prepayment of such note, such that the Oil and Gas Properties received and such
partial cash prepayment have an aggregate value not less than the value of the Oil and Gas
Properties that the Section 1031 Counterparty acquired from the Borrower.  

     Section 8.17   Use of Proceeds.  The Borrower will use the proceeds of the Loans and
will use Letters of Credit for general corporate purposes, including acquisitions, Investments,
working capital, repayment of Debt and the making of Restricted Payments, in each case to the
extent not otherwise prohibited hereunder; provided that the aggregate amount of LC Exposure under
all Letters of Credit used as credit support for any Credit Party’s obligations under any Swap
Agreement shall not exceed an amount equal to (a) C$7,500,000 minus (b) the amount of cash or
treasury securities subject to Liens permitted by Section 9.03(k).  

     Section 8.18   Fiscal Year.  The Borrower’s fiscal year shall end on December 31.  

     Section 8.19   New Parent Joinder.  Promptly, and in any event prior to the earlier to
occur of (a) the date on which 100% of the Equity Interests in the Borrower is transferred from QRI
to New Parent and (b) the date of a Qualified IPO, the Borrower will cause New Parent to execute

additional closing documents, certificates, and legal opinions as shall reasonably be requested by
the Administrative Agent.  New Parent’s execution and delivery of the foregoing agreements and
other documentation is herein referred to collectively as the “New Parent Joinder”.  In
order to facilitate the transfer of the Equity Interests in the Borrower from QRI to New Parent,
the Administrative Agent undertakes and agrees that it will promptly redeliver to the Borrower, on
or prior to the date on which such transfer is scheduled to occur but subject to customary escrow
arrangements, the share certificates in the Borrower together with undated, blank stock powers for
each such certificate, in each case previously delivered to the Administrative Agent by QRI.

(which may be zero) approved by the Required Lenders, and the Borrowing Base as so reduced shall
become the new Borrowing Base immediately upon the date of such issuance or assumption, effective
and applicable to the Borrower, the Agents, each Issuing Bank and the Lenders on

76

 

such date until
the next redetermination or modification thereof hereunder.  For purposes of this Section 9.02(n),
the “stated principal amount” shall mean the stated face amount of such Debt without giving
effect to any original issue discount;

     (o)     Any renewals, refinancings or extensions of (but, except to the extent permitted herein,
not increases in (except to cover premiums or penalties)) any Debt described in clauses (d), (e),
(j) or (n) of this Section 9.02 (other than Permitted Intercompany Debt); provided, however, that

     (t)     Debt incurred, created or suffered to exist by the Borrower to or in favor of (i) QRI
prior to the transfer by QRI to New Parent, directly or indirectly through a Parent HoldCo, of 100%

Debt does not exceed the value of the Equity Interests in the Borrower immediately prior to the
first incurrence or creation of such Debt (the “Qualified IPO Related Debt”), (ii) New
Parent (and, as applicable, a Parent HoldCo) upon the transfer of the Qualified IPO Related Debt

Equity Interests in the Borrower; provided that (x) at all times such Debt is subordinated in right
of payment to the Secured Indebtedness on terms satisfactory to the Administrative Agent, acting
reasonably, and (y) such Debt is settled and cancelled promptly after the completion of the
transfer of 100% of the Equity Interests of the Borrower to New Parent.  For greater certainty, the
foregoing proviso will not restrict the Borrower from settling the Qualified IPO Related Debt by
the issuance of Equity Interests in the Borrower.  

     For the avoidance of doubt, to the extent any Debt could be attributable to more than one
subsection of this Section 9.02, the Credit Parties may categorize all or any portion of such Debt
to any one or more subsections of this Section 9.02 as it elects and unless as otherwise expressly
provided, in no event shall (x) the same portion of any Debt be deemed to utilize or be
attributable to more than one subsection of this Section 9.02 or (y) any Credit Party utilize
Section 9.02(k) for the purposes of issuing unsecured senior notes or unsecured subordinated notes
in the capital markets.

such acquisition or such Person becoming a Restricted Subsidiary, as applicable, (ii) such Lien

shall secure only those obligations which it secures on the date of such acquisition or the date
such Person becomes a Restricted Subsidiary, as applicable, and extensions, renewals and
replacements of such obligations that are not in excess of the outstanding principal amount of such
obligations as of such acquisition date or date such Person becomes a Restricted Subsidiary
(provided, that such obligations and such extensions, renewals, and replacements thereof so secured
by such Lien, together with the Debt secured by Liens described in clause (h) below,
shall at no time exceed in the aggregate the greater of (x) C$10,000,000 and (y) 5% of the

construction or improvement, (iii) the Debt secured thereby does not exceed 100% of the cost of
acquiring, constructing or improving such fixed or capital assets, (iv) such Liens shall not apply

     (i)     Liens arising pursuant to Section 9.343 of the Texas Uniform Commercial Code or other
similar statutory provisions of other states or provinces with respect to production purchased from
others.  

     (j)     Liens on real property and improvements thereon (other than on Oil and Gas Properties).  

     (k)     Liens relating to any cash or treasury securities used as credit support for any Swap
Agreement in an aggregate amount not to exceed the difference of (i) C$7,500,000 minus (ii)
the aggregate amount of LC Exposure under all Letters of Credit used as credit support for any
Credit Party’s obligations under any Swap Agreement.  

     (l)     Liens not otherwise included in this Section 9.03 so long as the sum of (i) the lesser of
(A) the aggregate outstanding principal amount of the obligations of the Credit Parties secured
thereby and (B) the aggregate fair market value (determined as of the date such Lien is incurred)
of the assets subject thereto (as to the Credit Parties) plus (ii) the amount of cash that
is subject to Liens permitted by Section

78

 

9.03(k) at such time plus (iii) the aggregate

time the greater of (x) C$10,000,000 and (y) 6.25% of the Borrowing Base then in effect.  

     Notwithstanding the foregoing, (i) no Liens may at any time attach to (A) any Oil and Gas
Properties of the Credit Parties of the types described in clauses (a), (b), (c), (e) and (f) of
the definition of Oil and Gas Properties evaluated in the Reserve Report used in the most recent
determination of the Borrowing Base, or (B) any Equity Interests issued by the Borrower to QRI, New
Parent or to any other Person, or by any Restricted Subsidiary to any other Credit Party other
than, in the case of clause (A) or (B) above, Permitted Liens, and (ii) in no event may any Liens
on any Property of a Credit Party secure any obligation of any Credit Party under any Swap
Agreement other than Liens created pursuant to the Security Instruments and Liens permitted under
Section 9.03(k).  For the avoidance of doubt, to the extent any Lien could be attributable to more
than one subsection of this Section 9.03, the Credit Parties may categorize all or any portion of
such Lien to any one or more subsections of this Section 9.03 as it elects and unless as otherwise
expressly provided, in no event shall the same portion of any Lien be deemed to utilize or be
attributable to more than one subsection of this Section 9.03.

any of the other Credit Parties to, declare or make, or agree to pay or make, directly or
indirectly, any Restricted Payment, return any capital to its stockholders or make any distribution

Interests payable solely in additional shares of its Equity Interests or any other non-cash form
(other than Disqualified Capital Stock);

     (b)     the Borrower (but only from and after the New Parent Joinder) and Restricted Subsidiaries

     (c)     the Borrower and New Parent may make Restricted Payments pursuant to and in accordance
with stock option plans, equity plans or other benefit or compensation plans providing for payments

including Restricted Payments made under the foregoing clause (i)) up to an aggregate amount equal
to (1) the greater of (x) C$10,000,000 and (y) 6.25% of the Borrowing Base then in effect
plus (2) an amount equal to fifty percent (50%) of the net proceeds received by New Parent
from the sale or issuance of Equity Interests of New Parent (other than the Qualified IPO) if, in
the case of Restricted Payments made under this clause (ii), (A) no Default has occurred and is
continuing at the time such Restricted Payment is made or would result from the making of such
Restricted Payment, (B) the Borrower’s Minimum Liquidity after giving effect to such Restricted

Borrower to QRI so as to increase the stated capital of the Borrower to the fair market value of
the Equity Interests immediately prior to such dividend, and (ii) distribute to QRI any Debt
permitted by Section 9.02(t) as a return of capital in respect of the Equity Interests of the
Borrower then held by QRI.  

     For the avoidance of doubt, to the extent any Restricted Payment could be attributable to more
than one subsection of this Section 9.04, the Credit Parties may categorize all or any portion of
such Restricted Payment to any one or more subsections of this Section 9.04 as it elects and unless
as otherwise expressly provided, in no event shall the same portion of any Restricted Payment be
deemed to utilize or be attributable to more than one subsection of this Section 9.04.  

     Section 9.05   Repayment of Debt; Amendment of Indentures.  The Borrower will not, and
will not permit any other Credit Party to:

Permitted Additional Debt, provided, however, that the Credit Parties may (i) Redeem Permitted
Additional Debt up to an aggregate amount of C$7,500,000, (ii) Redeem additional Permitted

and (iii) Redeem Permitted Additional Debt in connection with any refinancing thereof permitted
pursuant to Section 9.02(o); provided further that the Borrower shall have the right to (x) prior
to the conversion referred to in clause (y) below, pay current interest on the Permitted
Intercompany Debt at the rate specified therein and (y) convert the Permitted Intercompany Debt
into Equity Interests of the Borrower at any time, which Equity Interests shall not have any
mandatory right or right at the option of the holder thereof to receive cash dividends or other
cash distributions.  

     (b)     amend, modify, waive or otherwise change, consent or agree to any amendment, modification,
waiver or other change to, any of the terms of the Permitted Additional Debt if (i) the effect
thereof would be to shorten its maturity to be less than 91 days after the Maturity Date or average
life or increase the amount of any payment of principal thereof or increase the rate or shorten any
period for payment of interest thereon, (ii) such action requires the payment of a consent fee that
has not been approved by the Administrative Agent (such approval not to be unreasonably withheld),
or (iii) the effect thereof would be to add any guarantor or surety, unless such guarantor or
surety also guarantees the Secured Indebtedness pursuant to the Guaranty Agreement and each of the
Borrower and such guarantor or surety otherwise complies with Section 8.13(c); or

80

 

     (c)     if the Borrower or any other Credit Party issues any Debt that is subordinated in
right of payment to the Secured Indebtedness, designate any other Debt (other than the Secured
Indebtedness, and any Permitted Additional Debt) as “designated senior indebtedness” or “designated
guarantor senior indebtedness” or give any such other Debt any other similar designation for the
purposes of any instrument under which that subordinated Debt is issued.

Investment to any one or more subsections of this Section 9.06 as it elects and unless as otherwise
expressly provided, in no event shall the same portion of any Investment be deemed to utilize or be

(o) and (p), the aggregate Investments thereunder shall be determined net of the cost of any such
Investment (x) that is subsequently sold, redeemed or repaid or (y) in an Unrestricted Subsidiary
that is subsequently designated as a Restricted Subsidiary.  

     Section 9.07   Designation and Conversion of Restricted and Unrestricted Subsidiaries.  (a) Unless designated as an Unrestricted Subsidiary on Schedule 7.10 as of the Effective Date or

Subsidiary and such Investment would be permitted to be made at the time of such designation under
Section 9.06(j), (p) or (q).

Parties from holding and developing the Properties or engaging in any business or activity
described on Schedule 9.08.  From and after the date hereof, the Credit Parties will not acquire or

jurisdiction reasonably acceptable to the Administrative Agent.  

     Section 9.09   Mergers, Etc.  The Borrower will not, and will not permit any other
Credit Party to, merge into or with or consolidate with any other Person, or sell, lease or
otherwise dispose of (whether in one transaction or in a series of transactions) all or
substantially all of its Property to any other Person (whether now owned or hereafter acquired) any
such transaction, a “consolidation”), or liquidate or dissolve; provided that

     (a)     any Restricted Subsidiary may (i) participate in a consolidation with (A) the Borrower
(provided that the Borrower shall be the continuing or surviving corporation), (B) any other
Restricted Subsidiary (provided that if a Guarantor is a party to such transaction, the survivor is
a Guarantor or becomes a party to the Guaranty Agreement as a Guarantor) or (C) any other
Subsidiary (provided that either (x) a Restricted Subsidiary shall be the continuing or surviving
Person or (y) if an Unrestricted Subsidiary is the continuing or surviving Person, (1) the
representations and warranties of the Credit Parties contained in each of the Loan Documents are
true and correct on and as of such date as if made on and as of the date of such consolidation (or,

     (b)     Any Credit Party may participate in a consolidation (other than as described in clause (a)
above) if, at the time thereof and immediately after giving effect thereto, no Default shall occur
and be

84

 

continuing and no Borrowing Base Deficiency would result therefrom and, such Credit Party is
the surviving entity or the recipient of any such sale, lease or other disposition of Property,
provided that no such consolidation shall have the effect of releasing the Borrower or any
Guarantor from any of its obligations under this Agreement or any other Loan Document;

     (c)     any sale of all or substantially all of the assets of any Restricted Subsidiary provided
that such sale is permitted by Section 9.10; and

     (d)     any Restricted Subsidiary may liquidate or dissolve if (i) the continued existence and
operation of such Restricted Subsidiary is no longer in the best interests of the Credit Parties
taken as a whole (as reasonably determined by a Responsible Officer of the Borrower), (ii) such
liquidation and dissolution is not disadvantageous in any material respect to the Lenders, and
(iii) at the time thereof and immediately after giving effect thereto, no Default shall occur and
be continuing and no Borrowing Base Deficiency would result therefrom.  

     Section 9.10   Sale of Properties and Termination of Oil and Gas Swap Agreements.  The
Borrower will not, and will not permit any other Credit Party to, sell, assign, farm-out, convey or
otherwise transfer (including by way of a Reclassification) any Oil and Gas Property evaluated in
the Reserve Report used in the most recent determination of the Borrowing Base or any interest
therein or any Restricted Subsidiary owning any such Oil and Gas Property or terminate, unwind,
cancel or otherwise dispose of any Oil and Gas Swap Agreement except for:

     (a)     the sale of Hydrocarbons in the ordinary course of business;

     (b)     farmouts of undeveloped acreage and assignments in connection with such farmouts or the
abandonment, farm-out, exchange, lease, sublease or other disposition of Oil and Gas Properties not
containing Proved Hydrocarbon Interests which were not evaluated in the Reserve Report used in the
most recent determination of the Borrowing Base in the ordinary cause of business;

     (c)     the sale or transfer of equipment or other assets that are no longer necessary or useful
or are obsolete for the business of the Credit Parties or are replaced by equipment or other assets
usable in the ordinary course of business, of at least comparable value;

     (d)     the sale or other disposition (including Casualty Events and Reclassifications) of such
Oil and Gas Property or any interest therein or any Restricted Subsidiary owning such Oil and Gas
Property or the termination, unwinding, cancelation or other disposition of Oil and Gas Swap
Agreements; provided that:

     (i)     except in the case of a Reclassification, the consideration received in respect of
such sale or other disposition shall be equal to or greater than the fair market value of
the Oil and Gas Property (other than in the case of a Casualty Event), interest therein or
Restricted Subsidiary subject of such sale or other disposition (as reasonably determined by
any Responsible Officer of the Borrower);

     (ii)     no Event of Default or Borrowing Base Deficiency exists or results from such
termination, unwind, cancellation, sale or disposition (including any Casualty Event or
Reclassification);

     (iii)     if during any period between two successive Redetermination Dates the aggregate
amount of (A) the net cash proceeds received by the Borrower from the termination,

85

 

unwind,
cancelation or other disposition of such Oil and Gas Swap Agreements plus (B) the Recognized
Value of such Oil and Gas Properties sold or disposed of (including by way of Casualty
Events and Reclassifications) exceeds five percent (5%) of the Borrowing Base in effect
during such period, then the Borrowing Base shall be automatically reduced, effective
immediately upon such termination, unwind, cancellation, sale or disposition (including any
Casualty Event or Reclassification) by the amount that (x) aggregate value that the
Administrative Agent attributed to such Oil and Gas Swap Agreements and Oil and Gas
Properties in connection with the most recent determination of the Borrowing Base exceeds
(y) five percent (5%) of the Borrowing Base in effect immediately prior to such
redetermination, and the Borrowing Base as so reduced shall become the new Borrowing Base
immediately upon the date of such termination, unwind, cancellation, sale or disposition
(including Casualty Events and Reclassifications), effective and applicable to the Borrower,
the Agents, each Issuing Bank and the Lenders on such date until the next redetermination or
modification thereof hereunder;

     (iv)     if such termination, unwind, cancellation, sale or disposition (including
Reclassifications, but excluding Casualty Events) would result in an automatic
redetermination of the Borrowing Base pursuant to this Section 9.10, the Borrower shall have
delivered reasonable prior written notice thereof to the Administrative Agent;

     (v)     if a Borrowing Base Deficiency would result from such termination, unwind,
cancellation, sale or disposition (including Reclassifications but excluding Casualty
Events) as a result of an automatic redetermination of the Borrowing Base pursuant to this
Section 9.10, the Borrower prepays Borrowings, prior to or contemporaneously with the
consummation of such termination, unwind, cancellation, sale or disposition (including
Reclassifications but excluding Casualty Events), to the extent that such prepayment would
have been required under Section 3.04(c)(iii) (without giving effect to any 30-day period
for payment contained therein) after giving effect to such automatic redetermination of the
Borrowing Base; and

     (vi)     if a Borrowing Base Deficiency would directly result from a Casualty Event as a
result of an automatic redetermination of the Borrowing Base pursuant to this Section 9.10,
Section 3.04(c)(ii) shall apply.  

For purposes of this clause (d), such five percent (5%) shall be determined without giving effect
to any asset swaps of Oil and Gas Properties evaluated in the Reserve Report used in the most
recent determination of the Borrowing Base for other Oil and Gas Properties of equal or greater
Recognized Value;

     (e)     the sale of Oil and Gas Properties in connection with tax credit transactions complying
with §29 of the Code or any other analogous provision of the Code or of Canadian tax law whether
now existing or hereafter enacted, which sale does not result in a reduction in the right of any
Credit Party to receive the cash flow from such Oil and Gas Properties and which sale is on terms
reasonably acceptable to the Administrative Agent;

     (f)     transfers and other dispositions among the Borrower and the other Credit Parties subject
to compliance with Section 8.13;

     (g)     transfers permitted by Section 9.09; and

     (h)     transfer or assignment of the Existing Midstream Assets by the Borrower to an Unrestricted
Subsidiary in connection with the consummation of the Midstream Joint Venture.  

86

 

     Section 9.11   Transactions with Affiliates.  The Borrower will not, and will not permit
any other Credit Party to, enter into any transaction, including, without limitation, any purchase,
sale, lease or exchange of Property or the rendering of any service, with any Affiliate (other than
the Guarantors), unless such transactions are not otherwise prohibited under this Agreement and are
upon fair and reasonable terms no less favorable to it than it would obtain in a comparable arm’s
length transaction with
a Person not an Affiliate and provided that the Midstream Joint Venture (including the ongoing
transactions contemplated thereunder) and the IPO Tax Payments shall be permitted.  

     Section 9.12   Negative Pledge Agreements; Dividend Restrictions.  The Borrower will
not, and will not permit any other Credit Party to, create, incur, assume or suffer to exist any
contract, agreement or understanding which in any way prohibits or restricts the granting,
conveying, creation or imposition of any Lien on any of its Oil and Gas Property or its Equity
Interests in Restricted Subsidiaries in favor of the Administrative Agent and the Secured Parties
or restricts any Restricted Subsidiary from paying dividends or making distributions to the
Borrower or any Guarantor, or which requires the consent of or notice to other Persons in
connection therewith; provided, however, that the preceding restrictions will not apply to
encumbrances or restrictions arising under or by reason of (a) this Agreement or the Security
Instruments, (b) Debt permitted by Section 9.02 secured by Liens permitted by Section 9.03 (subject
to the penultimate sentence thereof and only to the extent related to the Property on which such
Liens were created), or any contract, agreement or understanding creating Liens permitted by
Section 9.03 (subject to the penultimate sentence thereof and only to the extent related to the
Property on which such Liens were created), (c) any leases or licenses or similar contracts as they
affect any Oil and Gas Property or Lien subject to a lease or license, (d) any restriction with
respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the direct or
indirect sale or disposition of all or substantially all the equity or Oil and Gas Property of such
Restricted Subsidiary (or the Oil and Gas Property that is subject to such restriction) pending the
closing of such sale or disposition, or (e) customary provisions with respect to the distribution
of Oil and Gas Property in joint venture agreements.  

     Section 9.13   Swap Agreements.  The Borrower will not, nor will the Borrower permit any
other Credit Party to, enter into any new Oil and Gas Swap Agreements which would cause the volume
of Hydrocarbons with respect to which a settlement payment is calculated under all Oil and Gas Swap
Agreements (including such new transactions) to which the Borrower and/or any other Credit Party is
a party as of the date such Oil and Gas Swap Agreements are entered into to exceed (a) (i) for the
calendar year in which such new Oil and Gas Swap Agreements are entered into (the “Initial
Measurement Period”), eighty-five percent (85%) of the aggregate of the Credit Parties’
anticipated production from Proved Hydrocarbon Interests for each of oil and gas (including natural
gas liquids), calculated separately, (ii) for the calendar year immediately following the end of
the Initial Measurement Period (the “Second Measurement Period”), eighty percent (80%) of
the aggregate of the Credit Parties’ anticipated production from Proved Hydrocarbon Interests for
each of oil and gas (including natural gas liquids), calculated separately, (iii) for the calendar
year immediately following the end of the Second Measurement Period (the “Third Measurement

     Section 10.01   Events of Default.  One or more of the following events shall constitute
an “Event of Default”:

     (a)     the Borrower shall fail to pay any principal of any Loan, or any reimbursement obligation

due date thereof or at a date fixed for prepayment thereof, by acceleration or otherwise.  

     (b)     the Borrower shall fail to pay any interest on any Loan, or any fee or any other amount
(other than an amount referred to in Section 10.01(a)) payable under any Loan Document, when and as

waiver under such Loan Document, or in any report, certificate, financial statement or other
document furnished pursuant to the provisions hereof or any Loan Document or any amendment or
modification thereof or waiver thereunder, shall prove to have been incorrect in any material
respect when made or deemed made (or, to the extent that any such representation and warranty is

such Sections prior to acceleration or the exercise of any remedy by the Lenders, then such Event
of Default shall be deemed to have been cured and/or waived without any further action by the
Administrative Agent or Lenders.  

     (f)     the Borrower or any other Credit Party shall fail to make any payment of principal in
respect of any Material Debt, when and as the same shall become due and payable, beyond any
applicable grace period provided with respect thereto and which failure shall continue uncured or
unremedied.  

     (g)     any event or condition occurs that results in any Material Debt becoming due prior to its
scheduled maturity or that enables or permits (with or without the giving of notice, but after the
expiration of any applicable grace period provided with respect thereto) the holder or holders of
any Material Debt or any trustee or agent on its or their behalf to cause any Material Debt to
become due, or to require the Redemption thereof, prior to its scheduled maturity or require any

secured Debt that becomes due as a result of the voluntary sale or transfer of the property or
assets securing such Debt or to the obligations of the Borrower, any Credit Party or any Guarantor
in respect of any Swap Agreement unless such Person is the defaulting party under such Swap
Agreement and as a result thereof such Swap Agreement has been terminated.  

     (h)     an involuntary proceeding shall be commenced or an involuntary petition shall be filed
seeking (i) liquidation, reorganization or other relief in respect of any Credit Party or its
debts, or of a substantial part of its assets, under any Federal, state or foreign bankruptcy,
insolvency, receivership or similar law now or hereafter in effect, including, without limitation,
under the Bankruptcy and Insolvency Act (Canada), the Companies Creditors Arrangement Act (Canada)
or the Winding-up and Restructuring Act (Canada), or (ii) the appointment of a receiver, trustee,
custodian, sequestrator, conservator or similar official for any Credit Party or for a substantial
part of its assets, and, in any such case, such proceeding or petition shall continue undismissed
for 60 consecutive days or an order or decree approving or ordering any of the foregoing shall be
entered.  

     (i)     any Credit Party shall (i) voluntarily commence any proceeding or file any petition
seeking liquidation, reorganization or other relief under any Federal, state or foreign bankruptcy,
insolvency, receivership or similar law now or hereafter in effect, including, without limitation,
under the Bankruptcy and Insolvency Act (Canada), the Companies Creditors Arrangement Act (Canada)
or the Winding-up and Restructuring Act (Canada), (ii) consent to the institution of, or fail to
contest in a timely and appropriate manner, any proceeding or petition described in Section
10.01(h), (iii) apply for or consent to the appointment of a receiver, trustee, custodian,

thereof and the same shall remain undischarged for a period of 60 consecutive days during which
execution shall not be effectively stayed, bonded or satisfied.  

     (l)     any of the Loan Documents after delivery thereof shall for any reason, except to the
extent permitted by the terms thereof, cease to be in full force and effect and valid, binding and
enforceable in accordance with their terms against the Borrower or a Guarantor party thereto or
shall be repudiated by any of them in writing, or any of the Security Instruments cease to create a
valid and perfected Lien of the priority required thereby on any of the collateral purported to be
covered thereby, except to the extent permitted by the terms of this Agreement, or any Credit Party
or any of their Affiliates shall so state in writing.  

     (m)     an ERISA Event or Canadian Pension Plan Termination Event shall have occurred that, in the
opinion of the Majority Lenders, when taken together with all other ERISA Events or Canadian
Pension Plan Termination Events that have occurred, would reasonably be expected to result in a
Material Adverse Effect.  

     (n)     a Change in Control shall occur.  

     Section 10.02   Remedies.  (a) In the case of an Event of Default other than one
described in Section 10.01(h), Section 10.01(i) or Section 10.01(j), at any time thereafter during
the continuance of such Event of Default, the Administrative Agent may, and at the request of the
Majority Lenders, shall, by notice to the Borrower, take either or both of the following actions,
at the same or different times: (i) terminate the Commitments, and thereupon the Commitments shall
terminate immediately, and (ii) declare the Notes and the Loans then outstanding to be due and
payable in whole (or in part, in which case any principal not so declared to be due and payable may
thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared
to be due and payable, together with accrued interest thereon and all fees and other obligations of
the Borrower and the Guarantors accrued hereunder and under the Notes and the other Loan Documents
(including, without limitation, the payment of cash collateral to secure the LC Exposure as
provided in Section 2.08(j)), shall become due and payable immediately, without presentment,
demand, protest, notice of intent to accelerate, notice of acceleration or other notice of any
kind, all of which are hereby waived by the Borrower and each Guarantor; and in case of an Event of
Default described in Section 10.01(h), Section 10.01(i) or Section 10.01(j), the Commitments shall
automatically terminate and the Notes and the principal of 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 Notes and the other Loan Documents (including, without
limitation, the payment of cash collateral to secure the LC Exposure as provided in Section
2.08(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.  

     (b)     In the case of the occurrence of an Event of Default, the Administrative Agent and the
Lenders will have all other rights and remedies available at law and equity.  

     (c)     All proceeds realized from the liquidation or other disposition of collateral or otherwise
received after maturity of the Notes, whether by acceleration or otherwise, shall be applied:

     (iii)     third, pro rata to payment of accrued interest on the Loans;

     (vi)     sixth, to serve as cash collateral to be held by the Administrative Agent to secure
the LC Exposure; and

     (vii)     seventh, any excess, after all of the Secured Indebtedness shall have been
indefeasibly paid in full in cash or cash collateralized, shall be paid to the Borrower or as
otherwise required by any Governmental Requirement.  

ARTICLE 11

The Agents

     Section 11.01   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 not have any 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 have no
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 not
have any duty to disclose, and shall not be liable for the failure to disclose, any information
relating to the Borrower, New Parent or any of their respective 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 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

91

 

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 6 or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to the Administrative Agent or 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, New Parent and their respective 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 6, 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, the
Required 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) 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,
the Required 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 the Co-Documentation Agents 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
provided in Section 12.02), and otherwise the Administrative Agent shall not be liable for any
action taken or not taken by it in its capacity as the Administrative Agent 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

92

 

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
each Issuing Bank 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 of 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 of
its duties and exercise its rights and powers through their respective Related Parties.  The
exculpatory provisions of the preceding Sections of this Article 11 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 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, each Issuing Bank and the
Borrower.  Upon any such resignation, 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 Agent gives notice of its resignation, then the retiring Agent may, on behalf of the
Lenders and each Issuing Bank, appoint a successor Agent which shall be a bank with an office in
Canada or the United States, or an Affiliate of any such bank.  Upon the acceptance of its
appointment as Agent hereunder by a successor, such successor shall succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent
shall be discharged from its duties and obligations hereunder.  The fees payable by the Borrower to
a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor.  After the Agent’s resignation hereunder, the provisions
of this Article 11 and Section 12.03 shall continue in effect for the benefit of such retiring
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 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, New Parent 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 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 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

93

 

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, New Parent or any of their respective
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, New Parent or their respective
Subsidiaries.  Except for notices, reports and other documents and information expressly required
to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or Arranger 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 any of its Affiliates.  In this
regard, each Lender acknowledges that Vinson & Elkins L.L.P.  and Blake, Cassels & Graydon LLP
are 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, New Parent or any of their
respective 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 Indebtedness that are owing and unpaid and to
file such other documents as may be necessary or advisable in order to have the 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 Indebtedness 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 or subordinate
any Oil and Gas Property (other than, in the case of any such subordination, any Oil and Gas
Property of the type described in clauses (a), (b), (c), (e) and (f) of the definition thereof
evaluated in the Reserve Report

94

 

used in the most recent determination of the Borrowing Base) or
other collateral that is permitted to be sold, Reclassified or released or be subject to a Lien
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, Reclassification or other
disposition of Oil or Gas Property to the extent such sale, Reclassification or other disposition
is permitted by the terms of Section 9.10 or is otherwise authorized by the terms of the Loan
Documents.  

     Section 11.11   The Arrangers, Syndication Agent and 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.

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, any other Agent, each Issuing Bank 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 other 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 or the Maximum Credit Amount of any Lender without the
written consent of such Lender;

     (ii)     increase the Borrowing Base without the written consent of all of the Lenders,
decrease or maintain the Borrowing Base without the consent of Required Lenders or modify
Section 2.07 or 2.09 without the written consent of all of the Lenders (other than any
Defaulting Lender); provided that a Scheduled Redetermination may be postponed by the
Required Lenders;

     (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
Indebtedness 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 (which, for the avoidance of doubt, shall not include any mandatory
prepayment pursuant to Section 3.04(c)), or any interest thereon, or any fees payable
hereunder, or any other Secured Indebtedness 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;

96

 

     (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, or change Section 10.02(c), in each case, without the
written consent of each Lender;

     (vi)     waive or amend Section 3.04(c), Section 6.01, or Section 12.14, without the written
consent of each Lender (other than any Defaulting Lender);

     (vii)     release any Guarantor (except as set forth in the Guaranty Agreement, Section
8.13(d), Section 9.10(d) or Section 12.16) or release all or substantially all of the
collateral (other than as provided in Section 11.10), without the written consent of each
Lender (other than any Defaulting Lender);

     (viii)     change any of the provisions of this Section 12.02(b) or any other provision
hereof specifying the number or percentage of Lenders required to waive, amend or modify any
rights hereunder or under any other Loan Documents or make any determination or grant any
consent hereunder or any other Loan Documents, in each case to the extent that such provision
specifies that all Lenders (including Defaulting Lenders) must make any determination or
grant any consent hereunder or under any other Loan Documents, without the written consent of
each Lender; or

     (ix)     change the definitions of “Required Lenders” or “Majority Lenders” or any other
provisions hereof specifying the number or percentage of Lenders required to waive, amend or
modify any rights hereunder or under any other Loan Documents or make any determination or
grant any consent hereunder or any other Loan Documents to the extent that such provision
does not require the approval or consent of a Defaulting Lender, in each case without the
written consent of each Lender (other than any Defaulting Lender);

     provided, further, that no such agreement shall amend, modify or otherwise affect the rights
or duties of the Administrative Agent, any other Agent, or any Issuing Bank hereunder or under any
other Loan Document without the prior written consent of the Administrative Agent, such other
Agent, or such Issuing Bank, as the case may be.  Notwithstanding the foregoing, any supplement to
Schedule 7.10 (Subsidiaries) shall be effective, after compliance with the requirements of Section
12.17, 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.  

     Section 12.03   Expenses, Indemnity; Damage Waiver.  (a) The Borrower shall pay (i) all
reasonable and substantiated out-of-pocket expenses incurred by the Administrative Agent and its
Affiliates, including, without limitation, the reasonable and substantiated fees, charges and
disbursements of one (1) outside U.S.  counsel, one (1) outside Canadian counsel (on a solicitor and
his own client full indemnity basis), applicable local counsel and other outside consultants for
the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and other
similar expenses, and the cost of environmental audits and surveys and appraisals, in connection
with the syndication of the credit facilities provided for herein, the preparation, negotiation,
execution, delivery and administration (both before and after the execution hereof and including
advice of counsel to the Administrative Agent as to the rights and duties of the Administrative
Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any
amendments, modifications or waivers of or consents related to the provisions hereof or thereof
(whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all
reasonable and substantiated out-of-pocket costs, expenses, Taxes, assessments and other charges
incurred by any Agent or any Lender in connection with any filing, registration, recording or
perfection of any security interest contemplated by this Agreement or any Security Instrument or
any other document

97

 

referred to therein, (iii) all reasonable and substantiated out-of-pocket expenses
incurred by each Issuing Bank in connection with the issuance, amendment, renewal or extension of
any Letter of Credit issued by such Issuing Bank or any demand for payment thereunder, (iv) all
out-of-pocket expenses incurred by any Agent, any Issuing Bank or any Lender, including the fees,
charges and disbursements of any counsel for any Agent, any Issuing Bank or any Lender (on a
solicitor and his own client full indemnity basis), in connection with the enforcement or
protection of its rights in connection with this Agreement or any other Loan Document, including
its rights under this Section 12.03, or in connection with the Loans made or Letters of Credit
issued hereunder, including, without limitation, all such out-of-pocket expenses incurred during
any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.  

     (b)     THE BORROWER SHALL INDEMNIFY EACH AGENT, EACH ARRANGER, EACH ISSUING BANK AND EACH LENDER,
AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN
“INDEMNITEE”) AGAINST, AND DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL
LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE FEES, CHARGES
AND DISBURSEMENTS OF ANY COUNSEL (ON A SOLICITOR AND HIS OWN CLIENT FULL INDEMNITY BASIS) FOR ANY
INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR
AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY
AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR
THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR
THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE
FAILURE OF ANY CREDIT PARTY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS
AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY
BREACH OF ANY 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 ANY ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE
DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH
LETTER OF CREDIT, OR (b) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE
NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN
CONNECTION THEREWITH, (v) ANY OTHER ASPECT OF THE LOAN DOCUMENTS, (vi) THE OPERATIONS OF THE
BUSINESS OF THE BORROWER, NEW PARENT AND THEIR RESPECTIVE SUBSIDIARIES, (vii) ANY ASSERTION THAT
THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY
INSTRUMENTS, (viii) ANY ENVIRONMENTAL LAW APPLICABLE TO ANY CREDIT PARTY OR ANY OF THEIR PROPERTIES
OR OPERATIONS, INCLUDING, THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE,
TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT OF HAZARDOUS MATERIALS ON OR AT ANY OF
THEIR PROPERTIES, (ix) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE CREDIT PARTIES, OR (x)
ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING 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

98

 

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 (X) ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL
AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH
INDEMNITEE, (Y) RELATE TO CLAIMS BETWEEN OR AMONG ANY OF THE LENDERS, THE ADMINISTRATIVE AGENT, THE
ARRANGERS OR ANY OF THEIR AFFILIATES, SHAREHOLDERS, PARTNERS OR MEMBERS OR (Z) ARE IN RESPECT OF
ANY PROPERTY FOR ANY OCCURRENCE ARISING FROM THE ACTS OR OMISSIONS OF THE ADMINISTRATIVE AGENT OR
ANY LENDER DURING THE PERIOD AFTER WHICH SUCH PERSON, ITS SUCCESSORS OR ASSIGNS HAVE OBTAINED
POSSESSION OF SUCH PROPERTY (WHETHER BY FORECLOSURE OR DEED IN LIEU OF FORECLOSURE, AS
MORTGAGEE-IN-POSSESSION OR OTHERWISE).  

     (c)     To the extent that the Borrower fails to pay any amount required to be paid by it to any
Agent, any Arranger, or any Issuing Bank under Section 12.03(a) or (b), each Lender severally
agrees to pay to such Agent, such Arranger, or such Issuing Bank, 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, such Arranger, or such Issuing Bank 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 not later than 30 days after
written demand therefor.  

     Section 12.04   Successors and Assigns.  (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 any Issuing Bank that issues any Letter of
Credit), except that (i) the 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 any 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, each Issuing Bank, and the
Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.  

     (b)     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

99

 

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) of:

     (A)     the Borrower, provided that no consent of the Borrower shall be required if
such assignment is to a Lender, an Affiliate of a Lender, an Approved Fund or, if an
Event of Default has occurred and is continuing, is to 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, Affiliate
of a Lender or an Approved Fund of a Lender immediately prior to giving effect to
such assignment.  

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

     (A)     except for an assignment of the entire remaining amount of the assigning
Lender’s Commitment or Loans, (1) in the case of an assignment to a Lender or an
Affiliate of a Lender, the amount of the unused Commitment and Loans 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 C$2,500,000 and the amount of the
Commitment or Loans of the assigning Lender after such assignment shall not be less
than C$2,500,000 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 and (2) in the case of an assignment to an
assignee other than a Lender or an Affiliate of a Lender, the amount of the
Commitment or Loans 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
C$5,000,000 and the amount of the unused Commitment and Loans of the assigning
Lender after such assignment shall not be less than C$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 C$3,500;

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

     (E)     in no event may any Lender assign all or a portion of its rights and
obligations under this Agreement to the Borrower or any Affiliate of the Borrower or
to any other Person that does not deal at arm’s length, within the meaning of the
Income Tax Act (Canada), with the Borrower; and

     (F)     the assignee must not be a Defaulting Lender.  

100

 

     (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 Maximum
Credit Amount 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 absent manifest error, and the Borrower, the
Administrative Agent, each Issuing Bank 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.  In connection with any changes to the
Register, if necessary, the Administrative Agent will reflect the revisions on Annex I and
forward a copy of such revised Annex I to the Borrower, each Issuing Bank and each Lender.  

     (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) 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) no such Participant shall
be a Person with whom the Borrower does not deal at arm’s length, within the meaning of the Income
Tax Act (Canada), (B) such Lender’s obligations under this Agreement shall remain unchanged, (C)
such Lender shall remain solely responsible to the other parties hereto for the performance of such
obligations and (D) the Borrower, the Administrative Agent, each Issuing Bank 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 agreement must provide that the
Participant be bound by the provisions of Section 12.03.  

101

 

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), provided that such Participant’s entitlements shall be no greater than the entitlements
of the Lender which sold such participation.  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 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.  

     (iii)     Each Lender that sells a participation shall, acting solely for this purpose as a
non-fiduciary agent of the Borrower, maintain a register on which it enters the name and
address of each participant and the principal amounts (and related interest amounts) of each
participant’s interest in the Loans or other obligations under this Agreement (the
“Participant Register”).  The entries in the Participant Register shall be
conclusive, absent manifest error, and such Lender shall treat each person whose name is
recorded in the Participant Register as the owner of such participation for all purposes of
this Agreement notwithstanding any notice to the contrary.  No Lender shall have any
obligation to disclose all or any portion of the Participant Register to the Borrower or any
other Person (including the identity of any participant or any information relating to a
participant’s interest in any obligations under any Loan Document) except to the extent that
such disclosure is necessary to establish that such commitment, loan, letter of credit or
other obligation is in registered form under Section 5f.103-1(c) of the United States
Treasury Regulations (or the Canadian equivalent).  For the avoidance of doubt, the
Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility
for maintaining a Participant Register.  

     (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 (or the
Canadian equivalent) or central 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 the Canadian equivalent) or to qualify the Loans
under the “Blue Sky” laws of any state or province.  

     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 other Agent, any Issuing Bank or any Lender may
have had notice or knowledge of any Default or any 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

102

 

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 11 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 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 Indebtedness 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 Indebtedness 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 Agents and other matters 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 telecopy or electronic mail 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.  If it becomes illegal for any Lender to hold
or benefit from a Lien over real property pursuant to any law, such Lender shall notify the
Administrative Agent and disclaim any benefit of such security interest to the extent of such
illegality, but such illegality shall not invalidate or render unenforceable such Lien for the
benefit of each of the other Lenders.  

     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
to time, to the fullest

103

 

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 limitation, obligations under Swap Agreements) at any time owing by such Lender or Affiliate
to or for the credit or the account of any Credit Party against any of and all the obligations of
any Credit Party 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.  (a) THIS AGREEMENT, THE NOTES AND ALL
CLAIMS OR CAUSES OF ACTION (WHETHER IN CONTRACT, TORT OR OTHERWISE) THAT MAY BE BASED UPON, ARISE
OUT OF OR RELATE IN ANY WAY TO THIS AGREEMENT OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE PROVINCE OF ALBERTA AND OF THE FEDERAL LAWS OF CANADA APPLICABLE THEREIN.  

     (b)     ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE
COURTS OF THE PROVINCE OF ALBERTA, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY
HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY,
GENERALLY AND UNCONDITIONALLY, THE 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

     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, each Issuing Bank
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 (provided that such Person agrees in writing to be bound by the provisions of
this Section 12.11) or (ii) any actual or prospective counterparty (or its advisors) to any
securitization or Swap Agreement relating to the Borrower and its obligations (provided that such
Person agrees in writing to be bound by the provisions of this Section 12.11), (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
any Credit Party relating to any Credit Party 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 a Credit Party; provided that, in the case of information received
from any Credit Party 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 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 Canada, the United States of America and the State of Texas 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
Notes, 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

105

 

such Lender on the principal amount of the Secured Indebtedness (or, to the extent that the principal amount of
the Secured Indebtedness 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 Indebtedness (or, to the extent that the principal amount of the Secured Indebtedness
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 actual full 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 (A) 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 (B) 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 been payable to such Lender if the total amount of interest had been computed without
giving effect to this Section 12.12.  To the extent that Chapter 303 of the Texas Finance Code is
relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender
elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time
to time in effect.  Chapter 346 of the Texas Finance Code does not apply to the Borrower’s
obligations hereunder.  

     Notwithstanding any provision herein to the contrary, in no event will the aggregate
“interest” (as defined in section 347 of the Criminal Code (Canada)) payable under this Agreement
exceed the maximum effective annual rate of interest on the “credit advanced” (as defined in that
section) permitted under that section and, if any payment, collection or demand pursuant to this
Agreement in respect of “interest” (as defined in that section) is determined to be contrary to the
provisions of that section, such payment, collection or demand will be deemed to have been made by
mutual mistake of the Borrower, any Guarantor, the Lenders, any Issuing Bank and any Agent, as the
case may be, and the amount of such excess payment or collection will be refunded to the Borrower
or such Guarantor, as the case may be.  For purposes of this Agreement, the effective annual rate
of interest will be determined in accordance with generally accepted actuarial practices and
principles over the term of the Loans on the basis of annual compounding of the lawfully permitted
rate of interest and, in the event of dispute, a certificate of a Fellow of the Canadian Institute
of Actuaries appointed by the Administrative Agent will be prima facie evidence, for the purposes
of such determination.  

     Section 12.13   EXCULPATION PROVISIONS.  EACH OF THE PARTIES HERETO SPECIFICALLY AGREES
THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS
CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT
IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE
TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL
COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS

106

 

AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS
RESPONSIBILITY FOR SUCH LIABILITY.  EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST
THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE
PROVISION IS NOT “CONSPICUOUS.”

     Section 12.14   Collateral Matters; Swap Agreements.  The benefit of the Security
Instruments and of the provisions of this Agreement relating to any collateral securing the Secured
Indebtedness shall also extend to and be available to the Secured Swap Providers (on a pro rata
basis in respect of any such obligations of any Credit Party to them) with respect to any Swap
Agreement, but excluding any additional transactions or confirmations entered into (a) after such
Secured Swap Provider ceases to be a Lender or an Affiliate of a Lender or (b) after assignment by
a Secured Swap Provider to a Person that is not a Lender or an Affiliate of a Lender at the time of
such assignment.  No Lender or any Affiliate of a Lender shall have any voting rights under any
Loan Document as a result of the existence of obligations owed to it under any such Swap
Agreements.  

     Section 12.15   No Third Party Beneficiaries.  This Agreement, the other Loan Documents,
and the agreement of the Lenders to make Loans and the Issuing Banks to issue, amend, renew or
extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person
(including, without limitation, any Subsidiary of the Borrower, any obligor, contractor,
subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges
hereunder or under any other Loan Document against the Administrative Agent, any other Agent, any
Issuing Bank, or any Lender for any reason whatsoever.  There are no third party beneficiaries.  

     Section 12.16   USA Patriot Act Notice.  Each Lender hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub.  L.  107-56 (signed into law
October 26, 2001)) (the “Act”), it is required to obtain, verify and record information
that identifies the Borrower, which information includes the name and address of the Borrower and
other information that will allow such Lender to identify the Borrower in accordance with the Act.  

     Section 12.17   Anti-Money Laundering Legislation.  (a) The Borrower acknowledges that,
pursuant to the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (Canada) and other
applicable anti-money laundering, anti-terrorist financing, government sanction and “know your
client” Laws, whether within Canada or elsewhere (collectively, including any guidelines or orders
thereunder, “AML Legislation”), the Lenders and the Administrative Agent may be required to
obtain, verify and record information regarding each Credit Party, its directors, authorized
signing officers, direct or indirect shareholders or other Persons in control of the applicable
Credit Party, and the transactions contemplated hereby.  Borrower shall promptly provide all such
information, including supporting documentation and other evidence, as may be reasonably requested
by any Lender or the Administrative Agent, or any prospective assign or participant of a Lender or
the Administrative Agent, in order to comply with any applicable AML Legislation, whether now or
hereafter in existence.  

(b)     If the Administrative Agent has ascertained the identity of any Credit Party or any authorized
signatories of the applicable Credit Party for the purposes of applicable AML Legislation, then the
Administrative Agent:

107

 

     (i)     shall be deemed to have done so as an agent for each Lender, and this Agreement
shall constitute a “written agreement” in such regard between each Lender and the
Administrative Agent within the meaning of applicable AML Legislation; and

     (ii)     shall provide to each Lender copies of all information obtained in such regard
without any representation or warranty as to its accuracy or completeness.  

Notwithstanding the preceding sentence and except as may otherwise be agreed in writing, each of
the Lenders agrees that the Administrative Agent has no obligation to ascertain the identity of any
Credit Party or any authorized signatories of the applicable Credit Party on behalf of any Lender,
or to confirm the completeness or accuracy of any information it obtains from the applicable Credit
Party or any such authorized signatory in doing so.  

     Section 12.18   No Fiduciary Duty.  Each Agent, Lender and their respective Affiliates
(collectively, solely for purposes of this paragraph, the “Banks”), may have economic
interests that conflict with those of the Borrower and the other Credit Parties, their stockholders
and/or their Affiliates (collectively, solely for purposes of this paragraph, the
“Obligors”).  The Borrower agrees that nothing in the Agreement or the Loan Documents or
otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or
other implied duty between any Bank, on the one hand, and any Obligor, on the other.  The Borrower
acknowledges and agrees that (a) the transactions contemplated by the Loan Documents (including the
exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions
between the Banks, on the one hand, and the Obligors, on the other, and (ii) in connection
therewith and with the process leading thereto, (x) no Bank has assumed an advisory or fiduciary
responsibility in favor of any Obligor with respect to the transactions contemplated hereby (or the
exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective
of whether any Bank has advised, is currently advising or will advise any Obligor on other matters)
or any other obligation to any Obligor except the obligations expressly set forth in the Loan
Documents and (y) each Bank is acting solely as principal and not as the agent or fiduciary of any
Obligor, its management, stockholders, creditors or any other Person.  The Borrower acknowledges
and agrees that it has consulted its own legal and financial advisors to the extent it deemed
appropriate and that it is responsible for making its own independent judgment with respect to such
transactions and the process leading thereto.  The Borrower agrees that it will not claim that any
Bank has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty
to any Obligor, in connection with such transaction or the process leading thereto.
