ARTICLE II .

THE CREDIT

     2.01 Amounts and Terms of the Commitments.

          (a) Each Lender severally agrees, on the terms and conditions set forth herein, to make loans
to the Company (each such loan, a “Loan”) from time to time on any Business Day during the period
from the Effective Date to the Termination Date, so long as (a) with respect to any Lender, such
Loans then requested to be made by such Lender do not exceed such Lender’s Pro Rata Share of the
aggregate amount of all Loans then requested from the Lenders, and (b) the aggregate amount of all
the Lenders’ Loans and the LC Obligation outstanding at any time does not exceed the Borrowing Base
in effect at such time. The obligation of the Company to repay to each Lender the aggregate amount
of all Loans made by such Lender, together with interest accruing in connection therewith, shall be
evidenced by a promissory note from the Company payable to the order of such Lender (herein called
such Lender’s “Note” and collectively, the “Notes”). The amount of principal owing on any Lender’s
Note at any given time shall be the aggregate amount of all Loans theretofore made by such Lender
minus all payments of principal theretofore received by such Lender on such Note. Interest
on each Note shall accrue and be due and payable as provided herein and therein. Subject to the
terms and conditions hereof, until the Termination Date, Company may borrow, repay, and reborrow
hereunder.

          (b) Subject to the terms and conditions of Section 2.10 below and relying upon the
representations and warranties herein set forth, the Issuing Lender for the account of the Lenders
agrees to issue Letters of Credit as support for payment obligations incurred by the Company in the
ordinary course of business upon the request of the Company at any time and from time to time on

Credit Agreement

17

 

and after the Effective Date and up to, but excluding, the Termination Date (the “Availability
Period”). No Letter of Credit will be issued in a face amount which, after giving effect to the
issuance of such Letter of Credit, would cause either the LC Obligation to exceed $500,000 or the
Effective Amount to exceed the Borrowing Base then in effect. If any Letter of Credit has been
drawn upon and the amount so drawn has not been reimbursed to the Issuing Lender, the Commitment of
each Lender shall be deemed to be utilized for all purposes hereof in an amount equal to such
Lender’s Pro Rata Share of the LC Obligations.

          (c) Upon not less than five (5) Business Days’ notice, the Company may (i) terminate the Loan
Documents and the Commitment of each Lender, provided that all Obligations are paid and discharged
in full concurrently with such termination or (ii) permanently reduce the unused portion of the
Maximum Loan Amount in an amount equal to $250,000 or any integral multiple of $250,000 in excess
thereof.

     2.02 Procedure for Borrowings.

          (a) Each Borrowing of Loans shall be made upon the Company’s irrevocable written notice
delivered to the Administrative Agent in the form of a Notice of Borrowing duly completed; which
notice must be received by the Administrative Agent prior to 11:00 a.m. (Chicago, Illinois time)
(i) three (3) Business Days prior to the requested Borrowing Date, in the case of LIBOR Loans; and
(ii) on the requested Borrowing Date, in the case of Base Rate Loans.

          (b) Each Notice of Borrowing shall specify (i) the amount of the Borrowing, which shall be in
an aggregate minimum amount (A) for Base Rate Loans equal to the lesser of (y) $250,000 or any
multiple integrals of $250,000 in excess thereof or (z) the unadvanced portion of the Available
Borrowing Base and (B) for LIBOR Loans $250,000 or any multiple integrals of $250,000 in excess
thereof (if the Available Borrowing Base as of such Borrowing Date will be less than $250,000, then
the Company may not request a LIBOR Loan); (ii) the requested Borrowing Date, which shall be a
Business Day; (iii) the Interest Rate Type of Loans comprising the Borrowing; and (iv) for LIBOR
Loans the duration of the Interest Period applicable to such Loans. If the Notice of Borrowing
fails to specify the duration of the Interest Period for any Borrowing comprised of LIBOR Loans,
such Interest Period shall be three months.

          (c) The number of tranches outstanding of Base Rate Loans and LIBOR Loans, whether under a
Borrowing, conversion or continuation, shall not exceed five (5) at any one time.

          (d) The Administrative Agent will promptly notify each Lender of its receipt of any Notice of
Borrowing and of the amount of such Lender’s Pro Rata Share of that Borrowing.

          (e) Provided the applicable conditions in Article V are met, each Lender will make the amount
of its Pro Rata Share of each Borrowing available to the Administrative Agent for the account of
the Company at the Administrative Agent’s Payment Office by 1:00 p.m. (Chicago, Illinois time) on
the Borrowing Date requested by the Company in funds immediately available to the Administrative
Agent. The proceeds of all such Loans will then be made available to the Company by the
Administrative Agent to the Company’s operating account with the Administrative Agent or by wire
transfer in accordance with written instructions provided to the Administrative Agent by the
Company of like funds as received by the Administrative Agent.

     2.03 Conversion and Continuation Elections.

          (a) During the period from the Effective Date to the Final Maturity Date, the Company may,
upon irrevocable written notice to the Administrative Agent in accordance with Subsection 2.03(b):
(i) elect, as of any Business Day, in the case of Base Rate Loans, or as of the last day of the
applicable Interest Period, in the case of LIBOR Loans, to convert any such Loans into Loans of any
other Interest Rate Type; or

Credit Agreement

18

 

(ii) elect as of the last day of the applicable Interest Period, to
continue any Loans having Interest Periods expiring on such day; provided, that if at any
time a LIBOR Loan in respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to less than $250,000, such LIBOR Loan shall automatically convert into a Base Rate
Loan.

          (b) The Company shall deliver a Notice of Conversion/Continuation to be received by the
Administrative Agent not later than 11:00 a.m. (Chicago, Illinois time) at least (i) three (3)
Business Days in advance of the Conversion/Continuation Date, if the Loans are to be converted into
or continued as LIBOR Loans; and (ii) on the Conversion/Continuation Date, if the Loans are to be
converted into Base Rate Loans, specifying: (A) the proposed Conversion/Continuation Date; (B) the
aggregate amount of Loans to be converted or continued; (C) the Interest Rate Type of Loans
resulting from the proposed conversion or continuation; and (D) other than in the case of
conversions into Base Rate Loans, the duration of the requested Interest Period.

          (c) If upon the expiration of any Interest Period applicable to LIBOR Loans, the Company has
failed to select timely a new Interest Period to be applicable to LIBOR Loans, or if any Default or
Event of Default then exists, the Company shall be deemed to have elected to convert such LIBOR
Loans into Base Rate Loans effective as of the expiration date of such Interest Period.

          (d) The Administrative Agent will promptly notify each Lender of its receipt of a Notice of
Conversion/Continuation, or, if no timely notice is provided by the Company, the Administrative
Agent will promptly notify each Lender of the details of any automatic conversion. All conversions
and continuations shall be made ratably according to the respective Lender’s Pro Rata Share of
outstanding principal amounts of the Loans with respect to which the notice was given.

     2.04 Optional Prepayments. Subject to Section 3.04, the Company may, at any time or from time
to time,

          (a) prepay Base Rate Loans, without premium or penalty, upon irrevocable notice to the
Administrative Agent of not less than one (1) Business Day, ratably as to each Lender, in whole or
in part, in aggregate minimum principal amounts of $250,000 or multiple integrals thereof (unless
the outstanding principal amount of all Base Rate Loans is less than $250,000, then such
prepayments shall be equal to such outstanding principal amount) and

          (b) prepay LIBOR Loans, without premium or penalty (but subject to Section 3.04) upon
irrevocable notice to the Administrative Agent of not less than three (3) Business Days, ratably as
to each Lender, in whole or in part, in aggregate minimum principal amounts of $250,000 or multiple
integrals thereof. Each such notice of prepayment shall specify the date and amount of such
prepayment and the Interest Rate Type(s) of Loans to be prepaid. The Administrative Agent will
promptly notify each Lender of its receipt of any such notice, and of such Lender’s Pro Rata Share
of such prepayment. The payment amount specified in such notice shall be due and payable on the
date specified therein.

     2.05 Borrowing Base Determinations, Mandatory Prepayments of Loans.

          (a) Scheduled Borrowing Base Determinations. At all times prior to the Final
Maturity Date, the Effective Amount shall not exceed the Borrowing Base then in effect. From and
after the Effective
Date, the initial Borrowing Base hereunder shall be $8,000,000, and the initial Borrowing Base
Reduction Amount shall be $250,000, in each case until redetermined pursuant to the terms of this
Section 2.05. Upon notice to the Company, the Borrowing Base and the Borrowing Base Reduction
Amount shall be redetermined for each Borrowing Base Period on each Scheduled Borrowing Base
Determination Date, and each such redetermination shall be effective as of the date set forth in
such notice of redetermination. The

Credit Agreement

19

 

Borrowing Base and the Borrowing Base Reduction Amount shall
be determined based upon the loan collateral value assigned to the Mortgaged Properties and such
other credit factors (including without limitation the assets, liabilities, cash flow, business,
properties, prospects, management and ownership of the Company and the Guarantors) which the
Lenders deem significant. The Lenders’ determination of the Borrowing Base and the Borrowing Base
Reduction Amount shall be in their sole discretion and shall not be subject to review or challenge
under Sections 11.18 and 11.19 hereof. Upon each redetermination of the Borrowing Base and the
Borrowing Base Reduction Amount, the Administrative Agent shall recommend to the Lenders a new
Borrowing Base and a new Borrowing Base Reduction Amount and the Lenders in accordance with their
customary policies and procedures for extending credit to Oil and Gas reserve-based customers shall
(by unanimous agreement in the case of Borrowing Base increases or Borrowing Base Reduction Amount
decreases and by agreement of the Super-Majority Lenders in the case of Borrowing Base decreases or
affirmations or Borrowing Base Reduction Amount increases or affirmations) establish the
redetermined Borrowing Base and Borrowing Base Reduction Amount. If the Company does not furnish
the Reserve Reports or all such other information and data by the date required, the Lenders may
nonetheless determine a new Borrowing Base and Borrowing Base Reduction Amount. It is expressly
understood that the Lenders shall have no obligation to determine the Borrowing Base or the
Borrowing Base Reduction Amount at any particular amount, either in relation to the Maximum Loan
Amount or otherwise.

          (b) Special Borrowing Base Determinations. In addition to Scheduled Borrowing Base
Determinations pursuant to Subsection 2.05(a), the Company and the Lenders may each request one (1)
additional redetermination of the Borrowing Base and Borrowing Base Reduction Amount during each
Borrowing Base Period (“Special Borrowing Base Determination”). In the event the Company requests a
Special Borrowing Base Determination pursuant to this Subsection 2.05(b), the Company shall deliver
written notice of such request to the Lenders which shall include: (i) Reserve Report(s) prepared
as of a date not more than thirty (30) calendar days prior to the date of such request, for the
benefit of the Lenders, and (ii) such other information as the Lenders shall request prepared as of
a date not more than thirty (30) calendar days prior to the date of such request. Likewise, in
the event the Lenders exercise their option for a Special Borrowing Base Determination, the
Administrative Agent shall give the Company notice of the redetermined Borrowing Base and Borrowing
Base Reduction Amount.

          (c) Interim Borrowing Base Reductions. On the last day of each month after each
Schedule Borrowing Base Determination Date or the date of each Special Borrowing Base
Determination, the Borrowing Base shall, automatically and without notice or further action, reduce
by the Borrowing Base Reduction Amount most recently determined or redetermined.

          (d) Mandatory Prepayment of Loans. If on any date a Borrowing Base Deficiency shall
exist as a result of a Borrowing Base redetermination or the application of a Borrowing Base
Reduction Amount, then the Company shall exercise any one or combination of the following (subject
to the proviso below): (i) make a mandatory principal prepayment in an amount equal to the amount
of the Borrowing Base Deficiency, either (x) in a lump sum payment within thirty (30) days after
such Borrowing Base redetermination or (y) in three (3) equal consecutive monthly installments
commencing on the last day of the month following the date of such Borrowing Base redetermination;
or (ii) within thirty (30) days after such Borrowing Base redetermination, pledge, or cause any
Guarantor to pledge, additional unencumbered collateral of sufficient value and character (as
determined by the Lenders in their sole discretion) that when added to the existing Collateral
shall cause the Borrowing Base to equal or exceed the Effective Amount; provided that if the
Borrowing Base Deficiency shall exist as the result of the application of any Borrowing
Base Reduction Amount or occurs after the Termination Date, the Borrower shall eliminate the
Borrowing Base Deficiency by making a lump sum payment within three (3) days after the Borrowing
Base Deficiency occurs.

Event of Default, interest shall be paid on demand of the Administrative Agent.

be from time to time modified or amended, the “Fee Letter”) between the Company and the
Administrative Agent of even date herewith, relating hereto.

     2.08 Computation of Fees and Interest.

          (a) All computations of interest for Base Rate Loans shall be made on the basis of a year of
365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and
interest shall be made on the basis of a 360-day year and actual days elapsed (which results in
more interest being paid than if computed on the basis of a 365-day year). Interest and fees shall
accrue during each period during which interest or such fees are computed from the first day
thereof to the last day thereof.

          (b) Each determination of an interest rate by the Administrative Agent shall be conclusive and
binding on the Company and the Lenders in the absence of manifest error.

     2.09 Payments by the Company; Borrowings Pro Rata.

          (a) All payments to be made by the Company shall be made without set-off, recoupment or
counterclaim. All payments by the Company shall be made in immediately available funds to the
Administrative Agent by credit to the Company’s operating account at the Administrative Agent’s
Payment Office for the account of the Administrative Agent or the Lender to whom such payment is
owed, and shall be made in dollars and in immediately available funds, no later than 11:00 a.m.
(Chicago, Illinois time) on the date specified herein. Except to the extent otherwise provided
herein, (i) each payment by the Company of fees shall be made pro rata for the account of the
Lenders in accordance with their respective Pro Rata Shares, (ii) each payment of principal of
Loans shall be made for the pro rata account of the Lenders in accordance with their respective
outstanding principal amount of Loans, and (iii) each payment of interest on Loans shall be made
for the account of the Lenders pro rata in accordance with their respective shares of the aggregate
amount of interest due and payable to the Lenders. Notwithstanding the foregoing, to the extent
money is received by the Administrative Agent pursuant to the exercise of remedies under the
Security Documents such money shall be applied to the pro rata payment of Obligations secured by
such Security Document.

          (b) The Administrative Agent will promptly distribute to each Lender its applicable share of
such payment in like funds as received. Any payment received by the Administrative Agent later
than 11:00 a.m. (Chicago, Illinois time) shall be deemed to have been received on the following
Business Day and any applicable interest or fee shall continue to accrue. When the Administrative
Agent collects or receives
money on account of the Obligations or otherwise pursuant to the Security Documents if such money
is insufficient to pay all such Obligations, such money shall be applied first to any
reimbursements due Administrative Agent under Section 11.05 or 11.06.

          (c) Subject to the provisions set forth in the definition of “Interest Period” herein,
whenever any payment is due on a day other than a Business Day, such payment shall be made on the
following Business Day, and such extension of time shall in such case be included in the
computation of interest or fees, as the case may be.

Credit Agreement

22

 

          (d) Unless the Administrative Agent receives notice from the Company prior to the date on
which any payment is due to the Lenders that the Company will not make such payment in full as and
when required, the Administrative Agent may assume that the Company has made such payment in full
to the Administrative Agent on such date in immediately available funds and the Administrative
Agent may (but shall not be so required), in reliance upon such assumption, distribute to each
Lender on such due date an amount equal to the amount then due such Lender. If and to the extent
the Company has not made such payment in full to the Administrative Agent, each Lender shall repay
to the Administrative Agent on demand such amount distributed to such Lender, together with
interest thereon for each day from the date such amount is distributed to such Lender until two
days following demand by the Administrative Agent at the Federal Funds Rate and for each day
thereafter until the date repaid at the Base Rate.

          (e) Except to the extent otherwise expressly provided herein, each borrowing hereunder shall
be from the Lenders pro rata in accordance with their respective Pro Rata Shares.

     2.10 Issuing the Letters of Credit.

          (a) Subject to the terms and conditions set forth herein, the Company may request the Issuing
Lender to issue Letters of Credit for its own account, in a form reasonably acceptable to the
Administrative Agent and the Issuing Lender, at any time and from time to time during the
Availability Period; provided that the Company may not request the issuance, amendment,
renewal or extension of Letters of Credit hereunder if the Effective Amount exceeds the Borrowing
Base at such time or would exceed the Borrowing Base as a result thereof.

          (b) In order to effect the issuance of a Letter of Credit, the Company shall submit a Notice
of Borrowing and a LC Application in writing by telecopy to the Administrative Agent (who shall
promptly notify the Issuing Lender) not later than 1:00 p.m., Chicago, Illinois time, three (3)
Business Days before the requested date of issuance of such Letter of Credit. Each such Notice of
Borrowing and LC Application shall (i) be signed by the Company, (ii) specify the Business Day on
which such Letter of Credit is to be issued, (iii) specify the purpose for the requested Letter of
Credit, (iv) specify the availability for Letters of Credit under (A) the Borrowing Base and (B)
the $500,000 aggregate LC Obligation limitation, as of the date of issuance of such Letter of
Credit, and (v) specify the expiry date thereof, which shall not be later than the earlier of (A)
twelve (12) months from the date of issuance of such Letter of Credit and (B) five (5) Business
Days prior to the Final Maturity Date.

          (c) Upon satisfaction of the applicable terms and conditions set forth in Article V, the
Issuing Lender shall issue such Letter of Credit to the specified beneficiary not later than the
close of business, Chicago, Illinois time, on the date so specified. The Administrative Agent shall
provide the Company and each Lender with a copy of each Letter of Credit so issued. Each such
Letter of Credit shall (i) provide for the payment of drafts, presented for honor thereunder by the
beneficiary in accordance with the terms thereon, at sight when accompanied by the documents
described therein and (ii) unless otherwise expressly agreed by the Issuing Lender and the Company
at the time such Letter of Credit is issued, be subject to the rules of the “International Standby
Practices 1998” or such later version as may be published by the
Institute of International Banking Law and Practice (the “ISP 1998”), or any successor entity, and
shall, as to matters not governed by the ISP 1998, be governed by, and construed and interpreted in
accordance with, the laws of the State of New York.

          (d) Upon the issuance date of each Letter of Credit, the Issuing Lender shall be deemed,
without further action by any party hereto, to have sold to each other Lender, and each other
Lender shall be deemed, without further action by any party hereto, to have purchased from the
Issuing Lender, a participation, to the extent of such Lender’s Pro Rata Share, in such Letter of
Credit, the obligations

Credit Agreement

23

 

thereunder and in the reimbursement obligations of the Company due in
respect of drawings made under such Letter of Credit. If requested by the Issuing Lender, the
other Lenders will execute any other documents reasonably requested by the Issuing Lender to
evidence the purchase of such participation.

          (e) Upon the presentment of any draft for honor under any Letter of Credit by the beneficiary
thereof which the Issuing Lender determines is in compliance with the conditions for payment
thereunder, the Issuing Lender shall promptly notify the Company, the Administrative Agent and each
Lender of the intended date of honor of such draft and the Company hereby promises and agrees, at
the Company’s option, to either (i) pay to the Administrative Agent for the account of the Issuing
Lender, by 11:00 a.m., Chicago, Illinois time, on the date payment is due as specified in such
notice, the full amount of such draft in immediately available funds or (ii) request a Loan
pursuant to the provisions of Subsection 2.01(a) and Section 2.02 of this Agreement in the full
amount of such draft, which request shall specify that the Borrowing Date is to be the date payment
is due under the Letter of Credit as specified in the Issuing Lender’s notice. If the Company
fails timely to make such payment because a Loan cannot be made pursuant to Subsection 2.01(a)
and/or Section 5.02, each Lender shall, notwithstanding any other provision of this Agreement
(including the occurrence and continuance of a Default or an Event of Default), make available to
the Administrative Agent for the benefit of the Issuing Lender an amount equal to its Pro Rata
Share of the presented draft on the day the Issuing Lender is required to honor such draft. If
such amount is not in fact made available to the Administrative Agent by such Lender on such date,
such Lender shall pay to the Administrative Agent for the account of the Issuing Lender, on demand
made by the Issuing Lender, in addition to such amount, interest thereon at the Federal Funds Rate
for the first two days following demand and thereafter until paid at the Base Rate. Upon receipt
by the Administrative Agent from the Lenders of the full amount of such draft, notwithstanding any
other provision of this Agreement (including the occurrence and continuance of a Default or an
Event of Default) the full amount of such draft shall automatically and without any action by the
Company, be deemed to have been a Base Rate Loan as of the date of payment of such draft. Nothing
in this Subsection 2.10(e) or elsewhere in this Agreement shall diminish the Company’s obligation
under this Agreement to provide the funds for the payment of, or on demand to reimburse the Issuing
Lender for payment of, any draft presented to, and duly honored by, the Issuing Lender under any
Letter of Credit, and the automatic funding of a Loan as in this subsection provided shall not
constitute a cure or waiver of the Event of Default for failure to provide timely such funds as in
this subsection agreed.

          (f) In order to induce the issuance of Letters of Credit by the Issuing Lender and the
purchase of participations therein by the other Lenders, the Company agrees with Administrative
Agent, Issuing Lender and the other Lenders that neither Administrative Agent nor any Lender
(including the Issuing Lender) shall be responsible or liable (except as provided in the following
sentence) for amounts paid by the Issuing Lender, as provided in Subsection 2.10(e), on account of
drafts so honored under the Letters of Credit, and the Company’s unconditional obligation to
reimburse the Issuing Lender through the Administrative Agent for such amounts shall not be
affected by, any circumstance, act or omission whatsoever (whether or not known to the
Administrative Agent or any Lender (including the Issuing Lender) other than a circumstance, act or
omission resulting from the gross negligence or willful misconduct of the Administrative Agent or
any Lender, including the Issuing Lender. The Company agrees that any action taken or omitted to be
taken by the Administrative Agent or any Lender (including the Issuing Lender) under or in
connection with any Letter of Credit or any related draft, document or Property shall be binding on
the Company and
shall not put the Administrative Agent or any Lender (including the Issuing Lender) under any
resulting liability to the Company, unless such action or omission is the result of the gross
negligence or willful misconduct of the Administrative Agent or any such Lender (including the
Issuing Lender). The Company hereby waives presentment for payment (except the presentment
required by the terms of any Letter of Credit) and notice of dishonor, protest and notice of
protest with respect to drafts honored under the Letters of Credit. The Issuing Lender agrees
promptly to notify the Company whenever a draft is presented under any Letter of Credit, but
failure to so notify the Company shall not in any way affect the Company’s obligations hereunder.
Subject to Section 3.07, if while any Letter of Credit is outstanding, any law, executive order or
regulation is

Credit Agreement

24

 

enforced, adopted or interpreted by any public body, governmental agency or court of
competent jurisdiction so as to affect any of the Company’s obligations or the compensation to any
Lender in respect of the Letters of Credit or the cost to such Lender of establishing and/or
maintaining the Letters of Credit (or any participation therein), such Lender shall promptly notify
the Company thereof in writing and within ten (10) Business Days after receipt by the Company of
such Lender’s request (through the Administrative Agent) for reimbursement or indemnification or
within thirty (30) days after receipt of a notice in respect of Taxes or Other Taxes, the Company
shall reimburse or indemnify such Lender, as the case may be, with respect thereto so that such
Lender shall be in the same position as if there had been no such enforcement, adoption or
interpretation, unless the Company notifies the Administrative Agent of its good faith contest to,
and dispute of, the requested amount. The foregoing agreement of the Company to reimburse or
indemnify the Lenders shall apply in (but shall not be limited to) the following situations: an
imposition of or change in reserve, capital maintenance or other similar requirements or in excise
or similar taxes or monetary restraints, except a change in franchise taxes imposed on such Lender
or in tax on the net income of such Lender.

          (g) In the event that any provision of a LC Application is inconsistent with, or in conflict
of, any provision of this Agreement, including provisions for the rate of interest applicable to
drawings thereunder or rights of setoff or any representations, warranties, covenants or any events
of default set forth therein, the provisions of this Agreement shall govern.

          (h) If the Obligations, or any part thereof, are declared or otherwise become immediately due
and payable pursuant to Article IX of this Agreement (for the purposes of this subsection, the
“Matured Obligations”), then all LC Obligations shall become immediately due and payable without
regard for actual drawings or payments on the Letters of Credit, and the Company shall be obligated
to pay to the Administrative Agent immediately an amount equal to the LC Obligations. All amounts
made due and payable by the Company under this Subsection 2.10(h) may be applied as the Issuing
Lender and the Lenders elect to any of the various LC Obligations; provided,
however, that such amounts applied by the Issuing Lender and the Lenders to the LC
Obligations shall be (i) first applied to the Matured LC Obligations, and (ii) second held by the
Administrative Agent for the benefit of the Issuing Lender and the Lenders as LC Collateral in the
LC Collateral Account until all remaining Matured Obligations have been satisfied. This
Subsection 2.10(h) shall not limit or impair any rights which the Administrative Agent, the Issuing
Lender or any of the Lenders may have under any other document or agreement relating to any Letter
of Credit or LC Obligation, including without limitation, any LC Application. The Company hereby
grants a security interest in and lien on the LC Collateral Account to the Administrative Agent for
and on behalf of the Lenders as security for the Obligations. The Company agrees to execute and
deliver from time to time such documentation as the Administrative Agent may reasonably request to
further assure such security interest.

     2.11 Payments by the Lenders to the Administrative Agent.

          (a) Unless the Administrative Agent receives notice from a Lender on or prior to the Effective
Date or, with respect to any Borrowing after the Effective Date, at least one (1) Business Day
prior to the date of such Borrowing, that such Lender will not make available as and when required
hereunder to the Administrative Agent for the account of the Company the amount of that Lender’s
Pro Rata Share of the
Borrowing, the Administrative Agent may assume that each Lender has made such amount available to
the Administrative Agent in immediately available funds on the Borrowing Date and the
Administrative Agent may (but shall not be so required), in reliance upon such assumption, make
available to the Company on such date a corresponding amount. If and to the extent any Lender
shall not have made its full amount available to the Administrative Agent in immediately available
funds and the Administrative Agent in such circumstances has made available to the Company such
amount, that Lender shall on the Business Day following such Borrowing Date make such amount
available to the Administrative Agent, together with interest at the Federal Funds Rate for the
first two days during such period and thereafter at the Base Rate. A notice of the Administrative
Agent submitted to any Lender with respect to amounts owing under this Subsection 2.11(a)

Credit Agreement

25

 

shall be
conclusive, absent manifest error. If such amount is so made available, such payment to the
Administrative Agent shall constitute such Lender’s Loan on the date of Borrowing for all purposes
of this Agreement. If such amount is not made available to the Administrative Agent on the
Business Day following the Borrowing Date, the Administrative Agent will notify the Company of such
failure to fund and, upon demand by the Administrative Agent, the Company shall pay such amount to
the Administrative Agent for the Administrative Agent’s account, together with interest thereon for
each day elapsed since the date of such Borrowing, at a rate per annum equal to the interest rate
applicable at the time to the Loans comprising such Borrowing.

          (b) The failure of any Lender to make any Loan on any Borrowing Date shall not relieve any
other Lender of any obligation hereunder to make a Loan on such Borrowing Date, but no Lender shall
be responsible for the failure of any other Lender to make the Loan to be made by such other Lender
on any Borrowing Date.

     2.12 Sharing of Payments, Etc. If any Lender shall obtain on account of the Obligations made
by it any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) or receive any collateral in respect thereof in excess of the amount such Lender was
entitled to receive pursuant to the terms hereof, such Lender shall immediately (a) notify the
Administrative Agent of such fact, and (b) purchase from the other Lenders such participations in
the Loans made by them as shall be necessary to cause such purchasing Lender to share the excess
payment according to the terms hereof; provided, however, that if all or any
portion of such excess payment is thereafter recovered from the purchasing Lender, such purchase
shall to that extent be rescinded and each other Lender shall repay to the purchasing Lender the
purchase price paid therefor, together with an amount equal to such paying Lender’s ratable share
(according to the proportion of (i) the amount of such paying Lender’s required repayment to (ii)
the total amount so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered. The Company agrees
that any Lender so purchasing a participation from another Lender may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of set-off, but subject
to Section 11.09) with respect to such participation as fully as if such Lender were the direct
creditor of the Company in the amount of such participation. The Administrative Agent will keep
records (which shall be conclusive and binding in the absence of manifest error) of participations
purchased under this Section and will in each case notify the Lenders following any such purchases
or repayments.

ARTICLE III .

TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01 Taxes.

          (a) Any and all payments by the Company to each Lender or the Administrative Agent under this
Agreement and any other Loan Document shall be made free and clear of, and without deduction or
withholding for any Taxes. In addition, the Company shall pay all Other Taxes.

          (b) The Company agrees to indemnify and hold harmless each Lender and the Administrative Agent
for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section) paid by the Lender or the Administrative Agent
and any liability (including penalties, interest, additions to tax and expenses) arising therefrom
or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted. Payment under this indemnification shall be made within thirty (30) days after the date
the Lender or the Administrative Agent makes written demand therefor.

Credit Agreement

26

 

          (c) If the Company shall be required by law to deduct or withhold any Taxes or Other Taxes
from or in respect of any sum payable hereunder to any Lender or the Administrative Agent, then:
(i) the sum payable shall be increased as necessary so that after making all required deductions
and withholdings (including deductions and withholdings applicable to additional sums payable under
this Section) such Lender or the Administrative Agent, as the case may be, receives an amount equal
to the sum it would have received had no such deductions or withholdings been made; (ii) the
Company shall make such deductions and withholdings; and (iii) the Company shall pay the full
amount deducted or withheld to the relevant taxing authority or other authority in accordance with
applicable law.

          (d) Upon request of the Administrative Agent, the Company shall furnish the Administrative
Agent the original or a certified copy of a receipt evidencing payment by the Company of Taxes or
Other Taxes under Subsection 3.01(c), or other evidence of payment satisfactory to the
Administrative Agent.

          (e) If the Company is required to pay additional amounts to any Lender or the Administrative
Agent pursuant to this Section 3.01, then upon written request of the Company such Lender shall use
reasonable efforts (consistent with legal and regulatory restrictions) to change the jurisdiction
of its Lending Office and take such other steps, in each case, so as to eliminate any such
additional payment by the Company which may thereafter accrue, if such change or step, as
applicable, in the judgment of such Lender is not otherwise disadvantageous to such Lender.

          (f) If the Company pays any additional amounts under this Section 3.01 to a Lender and such
Lender determines that it has actually received or realized in connection therewith any refund or
reduction of, or credit against, its tax liability in or with respect to the taxable year in which
the additional amount is paid (a “Tax Benefit”), such Lender shall pay to the Company an amount
that such Lender shall determine is equal to the net benefit after tax, which was obtained by such
Lender in such year as a consequences of such Tax Benefit. If the Company determines in good faith
that a reasonable basis exists for contesting any Taxes or Other Taxes with respect to which the
Company has paid any additional amounts under this Section 3.01 or for which indemnification has
been demanded hereunder, the relevant Lender or Administrative Agent, as applicable, may, in its
discretion, not to be unreasonably withheld, cooperate with the Company in challenging such Taxes
or Other Taxes at the Company’s expense if so requested by the Company in writing.

     3.02 Illegality.

          (a) If any Lender determines that the introduction of any Requirement of Law, or any change in
any Requirement of Law, or in the interpretation or administration of any Requirement of Law, has,
since the Effective Date, made it unlawful, or that, since the Effective Date, any central bank or
other Governmental Authority has asserted that it is unlawful, for any Lender or its applicable
Lending Office to
make LIBOR Loans, then, on notice thereof by the Lender to the Company through the Administrative
Agent, any obligation of that Lender to make LIBOR Loans shall be suspended until the Lender
notifies the Administrative Agent and the Company that the circumstances giving rise to such
determination no longer exist; such notice to be promptly given upon the determination that such
circumstances no longer exist.

          (b) If a Lender determines that it is unlawful to maintain any LIBOR Loan, the Company shall,
upon its receipt of notice of such fact and demand from such Lender (with a copy to the
Administrative Agent), convert such LIBOR Loans of that Lender then outstanding, together with
interest accrued thereon and amounts required under Section 3.04 into a Base Rate Loan without
regard to conditions precedent described in Subsection 5.02(b), either on the last day of the
Interest Period thereof, if the Lender may lawfully continue to maintain such LIBOR Loans to such
day, or immediately, if the Lender may not lawfully continue to maintain such LIBOR Loan. If the
Company is required to so prepay any LIBOR Loan, then

Credit Agreement

27

 

concurrently with such prepayment, the
Company shall borrow from the affected Lender, in the amount of such repayment, a Base Rate Loan.

          (c) If the obligation of any Lender to make or maintain LIBOR Loans has been so terminated or
suspended, all Loans which would otherwise be made by the Lender as LIBOR Loans shall be instead
Base Rate Loans.

          (d) Before giving any notice to the Administrative Agent under this Section, the affected
Lender shall designate a different Lending Office with respect to its LIBOR Loans if such
designation will avoid the need for giving such notice or making such demand and will not, in the
judgment of the Lender, be illegal or otherwise disadvantageous to the Lender.

     3.03 Increased Costs and Reduction of Return.

          (a) If any Lender determines, after the Effective Date, that, due to either (i) the
introduction of or any change (other than any change by way of imposition of or increase in reserve
requirements included in the calculation of the LIBOR) in or in the interpretation of any law or
regulation or (ii) the compliance by that Lender with any guideline or request from any central
bank or other Governmental Authority (whether or not having the force of law), there shall be any
increase in the cost to such Lender of agreeing to make or making, funding or maintaining any LIBOR
Loans, (except for any such increased cost resulting from taxes of any kind, including Taxes and
Other Taxes, as to which Section 3.01 shall govern) then the Company shall be liable for, and shall
from time to time, upon demand (with a copy of such demand to be sent to the Administrative Agent),
pay to the Administrative Agent for the account of such Lender, additional amounts as are
sufficient to compensate such Lender for such increased costs.

          (b) If any Lender shall have determined, after the Effective Date, that (i) the introduction
of any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy Regulation, (iii) any
change in the interpretation or administration of any Capital Adequacy Regulation by any central
bank or other Governmental Authority charged with the interpretation or administration thereof, or
(iv) compliance by the Lender (or its Lending Office) or any corporation controlling the Lender
with any Capital Adequacy Regulation, affects or would affect the amount of capital required or
expected to be maintained by the Lender or any corporation controlling the Lender and (taking into
consideration such Lender’s or such corporation’s policies with respect to capital adequacy and
such Lender’s desired return on capital) determines that the amount of such capital is increased as
a consequence of its Commitments, loans, credits or obligations under this Agreement, then, upon
demand of such Lender to the Company through the Administrative Agent, the Company shall pay to the
Lender, from time to time as specified by the Lender, additional amounts sufficient to compensate
the Lender for such increase.

     3.04 Funding Losses. The Company shall reimburse each Lender and hold each Lender harmless
from any loss or expense excluding consequential losses which the Lender may sustain or incur as a
consequence of: (a) the failure of the Company to make on a timely basis any payment of principal
of any LIBOR Loan; (b) the failure of the Company to borrow, continue or convert a Loan after the
Company has given (or is deemed to have given) a Notice of Borrowing or a Notice of
Conversion/Continuation (including by reason of the failure to satisfy any condition precedent
thereto); (c) the failure of the Company to make any prepayment in accordance with any notice
delivered under Section 2.04; (d) the prepayment (including pursuant to Section 2.05 or 2.06) or
other payment (including after acceleration thereof) of an LIBOR Loan on a day that is not the last
day of the relevant Interest Period; or (e) the automatic conversion under Section 2.03 of any
LIBOR Loan to a Base Rate Loan on a day that is not the last day of the relevant Interest Period;
including any such loss or expense arising from the liquidation or reemployment of funds obtained
by it to maintain its LIBOR Loans or from fees payable to terminate the deposits from which such
funds were obtained. For purposes of calculating amounts payable by the Company to the Lenders
under this Section and

Credit Agreement

28

 

under Subsection 3.03(a), each LIBOR Loan made by a Lender (and each related
reserve, special deposit or similar requirement) shall be conclusively deemed to have been funded
at the LIBOR used in determining the LIBOR for such LIBOR Loan by a matching deposit or other
borrowing in the interbank Eurodollar market for a comparable amount and for a comparable period,
whether or not such LIBOR Loan is in fact so funded.

     3.05 Inability to Determine Rates. If Administrative Agent determines that for any reason
adequate and reasonable means do not exist for determining the LIBOR for any requested Interest
Period with respect to a proposed LIBOR Loan, or that the LIBOR applicable pursuant to
Subsection 2.06(b) for any requested Interest Period with respect to a proposed LIBOR Loan does not
adequately and fairly reflect the cost to the Lenders of funding such Loan, the Administrative
Agent will promptly so notify the Company and each Lender. Thereafter, the obligation of the
Lenders to make or maintain LIBOR Loans hereunder shall be suspended until the Administrative Agent
upon the instruction of the Lenders revokes such notice in writing; such written revocation to be
promptly given upon determination that such circumstances no longer exist. Upon receipt of such
notice, the Company may revoke any Notice of Borrowing or Notice of Conversion/Continuation then
submitted by it. If the Company does not revoke such Notice, the Lenders shall make, convert or
continue the Loans, as proposed by the Company, in the amount specified in the applicable notice
submitted by the Company, but such Loans shall be made, converted or continued as Base Rate Loans
instead of LIBOR Loans.

     3.06 Certificates of Lenders. Any Lender claiming reimbursement or compensation under this
Article III shall deliver to the Company (with a copy to the Administrative Agent) a certificate
setting forth in reasonable detail the amount payable to the Lender hereunder and such certificate
shall be conclusive and binding on the Company in the absence of manifest error provided, however,
that such Lender shall only be entitled to collect amounts incurred within 180 days of such notice.

     3.07 Substitution of Lenders. Upon the receipt by the Company from any Lender (an “Affected
Lender”) of a claim for compensation under this Article III, the Company may: (a) obtain a
replacement Lender or financial institution satisfactory to the Administrative Agent (a
“Replacement Lender”) to acquire and assume all or a ratable part of all of such Affected Lender’s
Loans and Commitment; or (b) request one more of the other Lenders to acquire and assume all or
part of such Affected Lender’s Loans and Commitment but none of the Lenders shall have any
obligation to do so. Any such designation of a Replacement Lender under (a) shall be subject to
the prior written consent of the Administrative Agent which consent shall not be unreasonably
withheld or delayed.

     3.08 Survival. The agreements and obligations of the Company in this Article III shall
survive the payment of all other Obligations.

ARTICLE IV .

SECURITY

     4.01 The Security. The Obligations will be secured by the Security Documents described in
Schedule 4.01 and any additional Security Documents hereafter delivered by the Company or any
Guarantor and accepted by the Administrative Agent.

     4.02 Agreement to Deliver Security Documents. The Company and each Guarantor agrees to
deliver, to further secure the Obligations whenever requested by the Administrative Agent in its
sole and absolute discretion, deeds of trust, mortgages, chattel mortgages, security agreements,
financing statements and other Security Documents in form and substance reasonably satisfactory to
the Administrative Agent for the purpose of granting, confirming, and perfecting first and prior
liens or security interests in all Oil and Gas Properties now owned or hereafter acquired by the
Company or any Guarantor, subject to Permitted Liens.

Credit Agreement

29

 

The Company and each Guarantor also agrees
to deliver, whenever requested by the Lenders, title opinions from legal counsel acceptable to the
Lenders or such other evidence of title satisfactory to the Lenders with respect to the Mortgaged
Properties designated by the Lenders, based upon abstract or record examinations to dates
acceptable to the Lenders and (a) stating that the applicable member of the Borrower Group has good
and defensible title to such properties and interests, free and clear of all Liens except Permitted
Liens, (b) confirming that such Oil and Gas Properties are subject to Security Documents securing
the Obligations that constitute and create legal, valid and duly perfected deed of trust or
mortgage liens in such Oil and Gas Properties and assignments of and security interests in the Oil
and Gas attributable to such Oil and Gas Properties and the proceeds thereof, in each case subject
only to Permitted Liens, and (c) covering such other matters as the Lenders may reasonably request.

     4.03 Perfection and Protection of Security Interests and Liens. The Company and each
Guarantor will from time to time deliver to the Administrative Agent any financing statements,
amendment, assignment and continuation statements, extension agreements and other documents,
properly completed and executed if required by law (and acknowledged when required) by the Company
or any Guarantor, as applicable, in form and substance reasonably satisfactory to the
Administrative Agent, which the Administrative Agent reasonably requests for the purpose of
perfecting, confirming, or protecting any Liens or other rights in Collateral securing any
Obligations.

     4.04 Offset. To secure the repayment of the Obligations, the Company and each Guarantor
hereby grants the Administrative Agent and each Lender a security interest, a lien, and a right of
offset, each of which shall be in addition to all other interests, liens, and rights of the
Administrative Agent at common law, under the Loan Documents, or otherwise, and each of which shall
be upon and against (a) any and all moneys, securities or other property (and the proceeds
therefrom) of the Company or any Guarantor now or hereafter held or received by or in transit to
the Administrative Agent or any Lender from or for the account of the Company or any Guarantor,
whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all
deposits (general or special, time or demand, provisional or final) of the Company or any Guarantor
with the Administrative Agent or any Lender, and (c) any other credits and claims of the Company or
any Guarantor at any time existing against the Administrative Agent or any Lender, including claims
under certificates of deposit. During the existence of any Event of Default, the Administrative
Agent or any Lender is hereby authorized to foreclose upon, offset, appropriate, and apply, at any
time and from time to time, without notice to the Company or any Guarantor, any and all items
hereinabove referred to against the Obligations then due and payable.

     4.05 Subsidiary Guaranty.

and the Parent, shall promptly upon request by the Administrative Agent, execute and deliver to the
Administrative Agent an absolute and unconditional guaranty of the timely repayment, and the due
and punctual performance, of the Obligations of the Company hereunder, which Guaranty shall be
substantially in the form and substance of Exhibit G. Ivanhoe Energy Holdings Inc. and each such
Subsidiary and the Parent will deliver to the Administrative Agent, simultaneously with its
delivery of such a Guaranty, written evidence satisfactory to the Administrative Agent and its
counsel that such Subsidiary has taken all organizational action necessary to duly approve and
authorize its execution, delivery and performance of such Guaranty and any other documents which it
is required to execute.

          (b) The Company and each Guarantor are Affiliates and are mutually dependent on each other in
the conduct of their respective businesses, with the credit needed from time to time by each often
being provided by another or by means of financing obtained by one with the support of the other
for their mutual benefit and the ability of each to obtain such financing is dependent on the
successful operations of the

Credit Agreement

30

 

other. The board of directors or managers, where applicable, of each
Guarantor has determined that such Guarantor’s execution, delivery and performance of this
Agreement may reasonably be expected to directly or indirectly benefit such Guarantor and is in the
best interests of such Guarantor.

          (c) The direct or indirect value of the consideration received and to be received by such
Guarantor in connection herewith is reasonably worth at least as much as the liability and
obligations of each Guarantor hereunder, and the incurrence of such liability and obligations in
return for such consideration may reasonably be expected to benefit such Guarantor, directly or
indirectly.

          (d) The Company and the Guarantors, taken as a whole, are Solvent on the date hereof. Each of
the Company and each Guarantor has capital which is adequate for the businesses in which such
Person is engaged and intends to be engaged. Neither of the Company nor any Guarantor has incurred
(whether hereby or otherwise), nor does the Company or any Guarantor intend to incur or believe
that it will incur, liabilities which will be beyond its ability to pay as such liabilities mature.

     4.06 Assignment of Production.

          (a) The Company shall provide to Administrative Agent undated letters in blank to purchasers
of production and disbursers of proceeds of production from or attributable to the Company’s
Mortgaged Properties, with the names and addressees left blank, authorizing and directing the
addressees to make future payments attributable to production from the Mortgaged Properties
directly to Administrative Agent for the ratable account of the Lenders.

          (b) The Company hereby designates Administrative Agent as its agent and attorney-in-fact, to
act in its name, place, and stead for the purpose of completing and delivering any and all of the
letters in lieu of transfer orders delivered by the Company to Administrative Agent, including,
without limitation, completing any blanks contained in such letters and attaching exhibits thereto
describing the relevant Collateral. The Company hereby ratifies and confirms all that
Administrative Agent shall lawfully do or cause to be done by virtue of this power of attorney and
the rights granted with respect to such power of attorney. This power of attorney is coupled with
the interest of Administrative Agent in the Collateral, shall commence and be in full force and
effect as of the date hereof and shall remain in full force and effect and shall be irrevocable so
long as any Obligation remains outstanding or unpaid or any Commitment exists. The powers conferred
on Administrative Agent by this appointment are solely to protect the interests of the secured
parties under the Loan Documents and shall not impose any duty upon Administrative Agent to
exercise any such powers. Administrative Agent shall be accountable only for amounts that it
actually receives as a result of the exercise of such powers and shall not be responsible to any of
the Company, Guarantors, or any other
Person for any act or failure to act with respect to such powers, except for Administrative
Agent’s gross negligence or willful misconduct.

     4.07 Assignment of Runs. Notwithstanding that, under of the Mortgages, the Company has
assigned to Administrative Agent for the ratable account of itself, the Issuing Lender, and the
Lenders (and any Affiliate thereof) all of the proceeds of production accruing to the Company’s
Mortgaged Properties covered thereby:

          (a) Until such time as an Event of Default shall have occurred and be continuing, the Company
shall be entitled to receive from the purchasers or disbursers of its production all such proceeds,
subject however to the liens created under the Mortgages. Upon the occurrence and during the
continuance of an Event of Default, Administrative Agent may deliver to the addressees the
letters-in-lieu described in Section 4.06 above and may exercise all rights and remedies granted
under the Mortgages, including the right to obtain possession of all proceeds of runs then held by
the Company or any Guarantor or to receive directly from the purchaser or disburser of production
such proceeds of production.

Credit Agreement

31

 

          (b) In no case shall any failure, whether intentional or inadvertent, by Administrative Agent
to collect directly any such proceeds of runs constitute in any way a waiver, rescission or release
of any of its rights under the Mortgages, nor shall any release of any other proceeds of runs or of
any rights of Administrative Agent to collect other proceeds of runs thereafter.

Material Adverse Effect; and (d) is in compliance in all material respects with all Requirements of
Law.

     6.02 Corporate Authorization; No Contravention. The execution, delivery and performance by
the Company and the Guarantors of this Agreement and each other Loan Document to which such Person

not: (a) contravene the terms of any of that Person’s Organization Documents; (b) conflict with or
result in any breach or contravention of, or the creation of any Lien under, any document
evidencing any Contractual Obligation to which such Person is a party that would be prior to the
Liens granted to the Administrative Agent for the benefit of the Lenders or otherwise that would
constitute a Material Adverse Effect or any order, injunction, writ or decree of any Governmental
Authority to which such Person or its property is subject; or (c) violate any Requirement of Law,
that would constitute a Material Adverse Effect.

     6.03 Governmental Authorization. No approval, consent, exemption, authorization, or other
action by, or notice to, or filing with, any Governmental Authority is necessary or required in
connection with the execution, delivery or performance by, or enforcement against, the Company or

actions, suits, proceedings, claims or disputes pending, or to the knowledge of the Company or any

Obligation in any respect which, individually or together with all such defaults, would reasonably

          (a) Each Plan is in compliance in all material respects with the applicable provisions of
ERISA, the Code and other federal or state law. Each Plan which is intended to qualify under
Section 401(a) of the Code has received a favorable determination letter from the IRS and to the
knowledge of the Company and the Guarantors, nothing has occurred which would cause the loss of
such qualification. The Company, the Guarantors and each ERISA Affiliate has made all required
contributions to any Plan subject to Section 412 of the Code, and no application for a funding
waiver or an extension of any amortization period pursuant to Section 412 of the Code has been made
with respect to any Plan.

          (b) There are no pending or, to the knowledge of Company or any Guarantor, threatened claims,
actions or lawsuits, or action by any Governmental Authority, with respect to any Plan which has
resulted or could reasonably be expected to result in a Material Adverse Effect. There has been no
prohibited transaction or violation of the fiduciary responsibility rules with respect to any Plan

reasonably expects to incur, any liability (and no event has occurred which, with the giving of
notice under Section 4219 of ERISA, would result in such liability) under Section 4201 or 4243 of
ERISA with respect to a Multiemployer Plan; and (v) neither the Company, any Guarantor nor any
ERISA Affiliate has engaged in a transaction that could be subject to Section 4069 or 4212(c) or
ERISA.

     6.08 Margin Regulations. The proceeds of the Loans shall be used solely for the purposes set
forth in and permitted by Section 7.16. Neither the Company nor any Guarantor is generally engaged
in the business of purchasing or selling Margin Stock or extending credit for the purpose of

     6.09 Title to Properties. Subject to Permitted Liens, the Company and each Guarantor have
good and defensible title to all of its Oil and Gas Properties evaluated
in the most recently delivered Reserve Report, and except for such defects in title as would
not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect,
and the Company and each Guarantor have good title to all other Oil and Gas Properties necessary or
used in the ordinary conduct of their respective businesses. After giving full effect to the
Permitted Liens, the Company or any Guarantor specified as the owner under the most recently
delivered Reserve Report owns the net interests in production attributable to the Oil and Gas
Properties as reflected in the most recently delivered Reserve Report, and the ownership of such
Properties shall not in any material respect obligate the Company or any Guarantor to bear the
costs and expenses relating to the maintenance, development and operations of each such Property in
an amount in excess of its working interest of each Property set forth in the most recently
delivered Reserve Report that is not offset by a corresponding proportionate increase in the
Company’s or any Guarantor’s net revenue interest in such Property. No consents or rights of first
refusal exist or remain outstanding with respect to the Company’s or any Guarantor’s interest in
the Mortgaged Properties assigned to it pursuant to any Acquisition of Oil and Gas Properties other
than Permitted Liens. As of the Effective Date, the Property of the Company and the Guarantors is
subject to no Liens, other than Permitted Liens.

     6.10 Oil and Gas Reserves. The Company and each Guarantor is and will hereafter be, in all
material respects, the owner of the Oil and Gas that it purports to own from time to time in and
under its Oil and Gas Properties, together with the right to produce the same. The Oil and Gas
Properties are not subject to

Credit Agreement

36

 

any Lien other than as set forth in the financial statements referred
to in Section 6.14, as disclosed to the Lenders in writing prior to the date of this Agreement and
Permitted Liens. All Oil and Gas have been and will hereafter be produced, sold and delivered in
accordance in all material respects with all applicable laws and regulations of governmental
authority; each of the Company and the Guarantors has complied in all material respects and will
hereafter use commercially reasonable efforts to comply with all material terms of each oil, gas
and mineral lease and any other agreement comprising its Oil and Gas Properties; and all such oil,
gas and mineral leases and other agreements have been and will hereafter be maintained in full
force and effect. Provided, however that nothing in this Section 6.10 shall prevent the Company or
any Guarantor from abandoning any well or forfeiting, surrendering, releasing or defaulting under
any lease in the ordinary course of business which is not disadvantageous in any way to the Lenders
and which, in the opinion of the Company or such Guarantor, is in its best interest, and the
Company and each Guarantor is and will hereafter be in compliance with all obligations hereunder.
All of the Company’s and each Guarantor’s Operating Agreements and Operating Leases with respect to
its Oil and Gas Properties are and will hereafter be enforceable in all material respects in
accordance with their terms except as such may be modified by applicable bankruptcy law or an order
of a court in equity.

     6.11 Initial Reserve Report. The Company has heretofore delivered to the Lenders a true and
complete copy of a report, dated effective as of December 31, 2005, prepared by Netherland, Sewell

adverse change in the amount of the estimated Oil and Gas shown in the Initial Reserve Report since
the date thereof, except for changes which have occurred as a result of production in the ordinary
course of business, and (d) the Initial Reserve Report does not omit any material statement or
information necessary to cause the same not to be misleading to the Lenders.

     6.12 Gas Imbalances. There are no gas imbalances, take or pay or other prepayments with
respect to any of the Oil and Gas Properties which would require the Company or any Guarantor to
deliver Oil and Gas produced from any of the Oil and Gas Properties at some
future time without then or thereafter receiving full payment therefor exceeding 50,000 Mcf of
gas (on an MMBTU equivalent basis) in the aggregate.

     6.13 Taxes. The Company and the Guarantors have filed all federal tax returns and reports
required to be filed, and have paid all federal taxes, assessments, fees and other governmental
charges levied or imposed upon them or their properties, income or assets otherwise due and
payable, except those which are being contested in good faith by appropriate proceedings and for
which adequate reserves have been provided in accordance with GAAP. The Company and the Guarantors
have filed all state and other non-federal tax returns and reports required to be filed, and have
paid all state and other non-federal taxes, assessments, fees and other governmental charges levied
or imposed upon them or their properties, income or assets prior to delinquency thereof, except

knowledge, there is no proposed tax assessment against the Company or any Guarantor that would, if

     6.14 Financial Condition.

          (a) The Company has heretofore furnished to the Lenders (i) the unaudited financial statements

Company or such Guarantor.

     7.06 Title Information.

          (a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve
Report required by Subsection 7.02(e), the Company will deliver title information in form and
substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties
evaluated by such Reserve Report that were not included in the immediately preceding Reserve

previously delivered to the Administrative Agent, satisfactory title information on at least 80% of
the total net present value (determined by a discount factor of 10%) of the proved Oil and Gas
Properties evaluated by such Reserve Report.

          (b) If the Company has provided title information for additional Properties under
Subsection 7.06(a), the Company shall, within 60 days of notice from the Administrative Agent that

least 80% of the net present value (determined by a discount factor of 10%) of the Oil and Gas
Properties evaluated by such Reserve Report.

          (c) If the Company is unable to cure any title defect requested by the Administrative Agent or
the Lenders to be cured within the 60-day period or the Company does not comply with the

Credit Agreement

43

 

requirements to provide acceptable title information covering 80% of the net present value
(determined by a discount factor of 10%) of the Oil and Gas Properties evaluated in the most recent
Reserve Report, such default shall not be a Default, but instead the Administrative Agent and/or
the Required Lenders shall have the right to exercise the following remedy in their sole discretion
from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as
to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that
the Administrative Agent or the Required Lenders are not reasonably satisfied with title to any
Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall
not count towards “the 80% requirement”, and the Administrative Agent may send a notice to the
Company and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as
determined by the Super-Majority Lenders to cause the Company to be in compliance with the
requirement to provide acceptable title information on 80% of the net present value (determined by
a discount factor of 10%) of the Oil and Gas Properties. This new Borrowing Base shall become
effective immediately after receipt of such notice.

     7.07 Additional Collateral. In connection with each redetermination of the Borrowing Base, the
Company shall review the Reserve Report and the list of current Mortgaged Properties (as described

the total net present value (determined by a discount factor of 10%) of the Oil and Gas Properties
evaluated in the most recently completed Reserve Report after giving effect to exploration and
production activities, acquisitions, dispositions and production. In the event that the Mortgaged
Properties do not represent substantially all of such total net present value, then the Company and
the Guarantors shall grant, within thirty (30) days of delivery of the certificate required under
Subsection 7.02(e), to the Administrative Agent or its designee as security for the Obligations a
first-priority Lien interest on additional Oil and Gas Properties not already subject to a Lien of
the Security Documents such that after giving effect thereto, the Mortgaged Properties will
represent substantially all of such total net present value. All such Liens will be created and
perfected by and in accordance with the provisions of deeds of trust, security agreements and
financing statements or other Security Documents, all in form and substance reasonably satisfactory
to the Administrative Agent or its designee and in sufficient executed (and acknowledged where
necessary or appropriate) counterparts for recording purposes.

reputable independent insurers, insurance with respect to its properties and business against loss
or damage of the kinds customarily insured against by Persons engaged in the same or similar
business, of such types and in such amounts as are customarily carried under similar circumstances
by such other Persons except where the failure to do so would not reasonably be expected to have a
Material Adverse Effect. The loss payable clauses or provisions in said insurance policy or
policies insuring any of the Collateral for the Loan shall be endorsed in favor of and made payable
to the Administrative Agent as its interests may appear and such policies shall name the
Administrative Agent and the Lenders as “additional insured” and provide that the insurer will give
at least 30 days prior notice of any cancellation to the Administrative Agent.

delinquency, all their respective obligations and liabilities, including: (a) all tax liabilities,
assessments and governmental charges or levies upon it or its properties or assets, unless the same

with GAAP are being maintained by the Company or such Guarantor; (b) all lawful claims which, if
unpaid, would by law become a Lien upon its property; and (c) all Indebtedness, as and when due and
payable, but subject to any subordination provisions contained in any instrument or agreement
evidencing such Indebtedness; except in each of (a), (b) and (c), where the failure to do so would
not reasonably be expected to have a Material Adverse Effect.

respects with all Requirements of Law of any Governmental Authority having jurisdiction over it or
its

officers, and independent public accountants, all at the expense of the Company or such Guarantor
and at such reasonable times during normal business hours and as often as may be reasonably
desired, upon reasonable advance notice to the Company or such Guarantor; provided,
however, when an Event of Default exists the Administrative Agent or any Lender may do any
of the foregoing at the expense of the Company or such Guarantor at any time during normal business
hours and without advance notice.

     7.13 Environmental Laws.

          (a) The Company and each Guarantor shall conduct its operations and keep and maintain its
property in compliance with all Environmental Laws and maintain all environmental, health and
safety permits, licenses and authorizations necessary for its operations and will maintain such in

reasonably necessary to continuously determine and assure that the Company’s and such Guarantor’s

shall be treated as an Obligation pari passu and secured pro rata under the Security Documents with
all Obligations otherwise

Effect (if not waived by the PBGC or by the Required Lenders, or if such event can be avoided by

otherwise required by any Governmental Authority.

     9.03 Rights Not Exclusive. The rights provided for in this Agreement and the other Loan
Documents are cumulative and are not exclusive of any other rights, powers, privileges or remedies
provided by law or in equity, or under any other instrument, document or agreement now existing or
hereafter arising.

ARTICLE X.

ADMINISTRATIVE AGENT

     10.01 Appointment and Authorization. Each of the Lenders and the Issuing Lender 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.

Credit Agreement

56

 

     10.02 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 not have any duty to take any
discretionary action or exercise any discretionary powers, except as provided in Section 10.03, and
(c) except as expressly set forth herein, the Administrative Agent shall have no duty to disclose,
and shall not be liable for the failure to disclose, any information relating to the Company or any
Guarantor that is communicated to or obtained by the Lender 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
Company or any Guarantor 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 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 V or elsewhere
herein, other than to confirm receipt of items expressly required to be delivered to the
Administrative Agent or as to those conditions precedent expressly required to be to the
Administrative Agent’s satisfaction, (vi) the existence, value, perfection or priority of any
collateral security or the financial or other condition of the Company or any Guarantor or any
other obligor or guarantor, or (vii) any failure by the Company 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.

     10.03 Action by Administrative Agent. The Administrative Agent shall not have any duty to
take any discretionary action or exercise any discretionary powers, except discretionary rights and
powers expressly contemplated hereby that the Administrative Agent is required to exercise in
writing as directed by the Required Lenders (or such other number or percentage of the Lenders as
shall be necessary under the circumstances as provided herein) 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 (i) receive written instructions from 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 herein) specifying the action to be taken and (ii) 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 Required Lenders in the written instructions (with indemnities)
described in this Section 10.03, 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. 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 Required Lenders or the Lenders (or such other number or percentage of the Lenders
as shall be necessary under the circumstances as provided herein), and otherwise the Administrative
Agent shall not be liable for any action taken or not taken by it hereunder or under any other Loan
Document

Credit Agreement

57

 

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.

     10.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely
upon, and shall not incur any liability for relying upon, any notice, request, certificate,
consent, statement, instrument, document or other writing believed by it to be genuine and to have
been signed or sent by the proper Person. The Administrative Agent also may rely upon any
statement made to it orally or by telephone and believed by it to be made by the proper Person, and
shall not incur any liability for relying thereon and the Company, the Guarantors, the Lenders and
the Issuing Lender hereby waive 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 Company
or any Guarantor), 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.

     10.05 Sub-agents. The Administrative Agent may perform any and all its duties and exercise
its rights and powers by or through any one or more sub-agents appointed by the Administrative
Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and
exercise its rights and powers through their respective Agent-Related Persons. The exculpatory
provisions of the preceding Sections of this Article X shall apply to any such sub-agent and to the
Agent-Related Persons 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.

     10.06 Administrative Agent as Lender. Administrative Agent 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 Administrative Agent, and it and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Company or any Guarantor or Affiliate thereof as
if it were not Administrative Agent hereunder.

     10.07 No Reliance. Each Lender acknowledges that it has, independently and without reliance
upon the Administrative 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 or any other Lender and based on
such documents and information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement, any other Loan
Document, any related agreement or any document furnished hereunder or thereunder. The
Administrative Agent shall not be required to keep themselves informed as to the performance or
observance by the Company or any Guarantor 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 Company or
any Guarantor. Except for notices, reports and other documents and information expressly required
to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent
shall have no duty or responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Company (or any of its Affiliates)
which may come into the possession of the Administrative Agent or any of its Affiliates. In this
regard, each Lender acknowledges that Haynes and Boone, LLP is acting in this transaction as
special counsel to the Administrative Agent only, except to the extent otherwise expressly stated
in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal
counsel to the extent that it deems necessary in connection with the Loan Documents and the matters
contemplated therein.

Credit Agreement

58

 

     10.08 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 Company or any Guarantor, 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 Company or any Guarantor) 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 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 11.04)
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 11.04.

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 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.

     10.09 Authority of Administrative Agent to Release Collateral and Liens. Each Lender and
Issuing Lender hereby authorizes the Administrative Agent to release any Collateral that is
permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and
Issuing Lender hereby authorizes the Administrative Agent to execute and deliver to the Company or
any Guarantor, at the Company’s or such Guarantor’s sole cost and expense, any and all releases of
Liens, termination statements, assignments, or other documents reasonably requested by the Company
or such Guarantor in connection with any sale or other disposition of property to the extent such
sale or other disposition is permitted by the terms of Section 8.02 or is otherwise authorized by
the terms of the Loan Documents.

     10.10 Reserved.

     10.11 Successor Administrative Agent. The Administrative Agent may resign as the
Administrative Agent upon 30 days’ notice to the Lenders. If the Administrative Agent resigns
under this Agreement, the Required Lenders shall appoint from among the Lenders a successor
administrative agent reasonably satisfactory to the Company in the same capacity as the retiring
Administrative Agent for the Lenders. If no successor administrative agent is appointed prior to
the effective date of the resignation of such retiring Administrative Agent, such retiring
Administrative Agent may appoint, after consulting with the Lenders, a successor administrative
agent from among the Lenders. Upon the acceptance of its appointment as successor administrative
agent hereunder, such successor administrative agent shall succeed to all the rights, powers and
duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such
successor administrative agent and the retiring Administrative Agent’s appointment, powers and
duties as the Administrative Agent shall be terminated. After any retiring Administrative Agent’s
resignation hereunder as the Administrative Agent, the provisions of this Article X and Sections
11.04 and 11.05 shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was the Administrative Agent

Credit Agreement

59

 

under this Agreement. If no successor administrative agent
has accepted appointment as the Administrative Agent in the same capacity as the retiring
Administrative Agent by the date which is 30 days following a retiring Administrative Agent’s
notice of resignation, the retiring Administrative Agent shall either withdraw its resignation or
may appoint as a successor administrative agent a commercial Lender organized under the laws of the
United States of America or of any State thereof having a commercial capital surplus of at least
$500,000,000.

     10.12 Withholding Tax.

          (a) If any Lender is a not a “United States person” within the meaning of Section 7701(a)(3)
of the Code (a “Foreign Lender”), such Foreign Lender agrees with and in favor of the
Administrative Agent, to deliver to the Administrative Agent prior to receipt of any payment
subject to withholding under the Code (or upon accepting an assignment or participation of an
interest herein), two duly signed completed copies of either IRS Form W-8BEN or any successor
thereto (relating to such Foreign Lender and entitling it to a complete exemption from withholding
tax on all payments to be made to such Foreign Lender by the Company pursuant to this Agreement) or
IRS Form W-8ECI or any successor thereto (relating to all payments to be made to such Foreign
Lender by the Company pursuant to this Agreement) or such other evidence satisfactory to the
Company that such Foreign Lender is entitled to a complete exemption from U.S. withholding tax,
including any exemption pursuant to Section 881(c) of the Code. Thereafter and from time to time,
each such Foreign Lender shall (i) promptly submit to the Company such additional duly completed
and signed copies of one of such forms (or such successor forms as shall be adopted from time to
time by the relevant United States taxing authorities) as may then be available under then current
United States laws and regulations to avoid, or such evidence as is satisfactory to the Company of
any available complete exemption from United States withholding taxes in respect of all payments to
be made to such Foreign Lender by the Company pursuant to this Agreement, and (ii) promptly notify
the Administrative Agent and the Company of any change in circumstances which would modify or
render invalid any claimed exemption.

          (b) Each Foreign Lender, to the extent it does not act or ceases to act for its own account
with respect to any portion of any sums paid or payable to that Lender under any of the Loan
Documents (for example, in the case of a typical participation by that Lender), shall deliver to
the Administrative Agent on the date when such Foreign Lender ceases to act for its own account
with respect to any portion of any such sums paid or payable, and at such other times as may be
necessary in the determination of the Administrative Agent (in the reasonable exercise of its
discretion), (i) two duly signed completed copies of the forms or statements required to be
provided by that Lender as set forth above, to establish the portion of any such sums paid or
payable with respect to which that Lender acts for its own account that is not subject to U.S.
withholding tax,
and (ii) two duly signed completed copies of IRS Form W-8IMY (or any successor thereto), together
with any information that is required by the Code and Treasury regulations promulgated thereunder
and any additional information that Lender chooses to transmit with such form, and any other
certificate or statement of exemption required under the Code, to establish that that Lender is not
acting for its own account with respect to a portion of any such sums payable to that Lender.

          (c) The Company shall not be required to pay any additional amount to any Foreign Lender
under Section 3.01: (i) with respect to any Taxes or Other Taxes required to be deducted or
withheld on the basis of the information, certificates or statements of exemption that Foreign
Lender transmits with an IRS Form W-8IMY pursuant to Subsection 10.12(b) or (ii) if that Foreign
Lender shall have failed to satisfy the foregoing provisions of this Section 10.12.

          (d) Each Lender that is a “United States person” within the meaning of Section 7701(a)(30) of
the Code (“Domestic Lender”) shall deliver to the Administrative Agent two duly signed completed
copies of IRS Form W-9. If that Domestic Lender fails to deliver such forms, then the Company may
withhold from

Credit Agreement

60

 

any interest payment to that Domestic Lender an amount equivalent to the applicable
back-up withholding tax imposed by the Code, without reduction. Thereafter and from time to time,
each such Domestic Lender shall (i) promptly submit to the Company such additional duly completed
and signed copies of one of such forms (or such successor forms as shall be adopted from time to
time by the relevant United States taxing authorities) as may then be available under then current
United States laws and regulations to avoid, or such evidence as is satisfactory to the Company of
any available exemption from United States withholding taxes in respect of all payments to be made
to such Domestic Lender by the Company pursuant to this Agreement, and (ii) promptly notify the
Company of any change in circumstances which would modify or render invalid any claimed exemption.

          (e) No Assignee shall be entitled to the benefits of Section 3.01 unless the Company is
notified of the assignment and such Assignee has complied with the requirements of this Section
10.12.

          (f) If any Lender is entitled to a reduction in the applicable withholding tax, the
Administrative Agent may withhold from any payment to such Lender an amount equivalent to the
applicable withholding tax after taking into account such reduction. If (i) a Lender does not
deliver the forms or other documentation required this Section 10.12 to the Administrative Agent,
or (ii) the Company is required by law to deduct and withhold from or in respect of any amounts
payable under any Loan Document to a Lender but is not required to pay additional amounts under
Section 3.01 with respect to such payment, then the Administrative Agent may deduct from any
payment to such Lender an amount equivalent to the applicable withholding tax.

          (g) If the IRS or any other Governmental Authority of the United States or other jurisdiction
asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or
for the account of any Lender (because the appropriate form was not delivered, was not properly
executed, or because such Lender failed to notify the Administrative Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or
for any other reason) such Lender shall indemnify the Administrative Agent fully for all amounts
paid, directly or indirectly, by the Administrative Agent as tax or otherwise, including penalties
and interest, and including any taxes imposed by any jurisdiction on the amounts payable to the
Administrative Agent under this Section, together with all costs and expenses (including Attorney
Costs). The obligation of the Lenders under this subsection shall survive the payment of all
Obligations and the resignation or replacement of the Administrative Agent.

Company or any Guarantor or other Person on account of any action taken or not taken by the
Administrative Agent or the Lenders in reliance upon such telephonic or facsimile notice. The

OF OR AS A RESULT OF ANY INDEMNIFIED PARTY’S NEGLIGENCE IN WHOLE OR IN PART, INCLUDING,

Credit Agreement

63

 

WITHOUT
LIMITATION, THOSE CLAIMS WHICH RESULT FROM THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE OF
THE INDEMNIFIED PARTY, OR ANY ONE OR MORE OF THEM; provided, that neither the Company nor
any Guarantor shall have any obligation hereunder to any Indemnified Person with respect to
Indemnified Liabilities to the extent same arise from (i) the gross negligence or willful
misconduct of any Indemnified Person or (ii) a claim or action asserted by one or more other
Indemnified Persons. The agreements in this Section shall survive payment of all other Obligations.

     11.06 Payments Set Aside. To the extent that the Company or any Guarantor makes a payment to
the Administrative Agent or the Lenders, or the Administrative Agent or the Lenders exercise their
right of set-off, and such payment or the proceeds of such set-off or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Administrative Agent or such Lender in
its discretion) to be repaid to a trustee, receiver or any other party, in connection with any
Insolvency Proceeding or otherwise, then (a) to the extent of such recovery the obligation or part
thereof originally intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b) each Lender
severally agrees to pay to the Administrative Agent upon demand its pro rata share of any amount so
recovered from or repaid by the Administrative Agent.

     11.07 Successors and Assigns. Except for all provisions in Section 11.08, the provisions of
this Agreement shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that, neither the Company nor any Guarantor may assign or
transfer any of its rights or obligations under this Agreement without the prior written consent of
the Administrative Agent and each Lender except in connection with a merger permitted hereunder.

     11.08 Assignments, Participations, etc.

          (a) Any Lender may upon written consent of the Administrative Agent, the Issuing Lender and
the Company, which consent shall not be unreasonably withheld (provided at any time that an Event
of Default has occurred and is continuing, no approval from the Company shall be required), at any
time, assign and delegate to one or more Eligible Assignees (provided that no written
consent of the Administrative Agent or the Issuing Lender shall be required in connection with any
assignment and delegation by the Lender to an Eligible Assignee that is an Affiliate of such
Lender) (each an “Assignee”) all, or any ratable part of all in a minimum commitment amount at
least equal to $2,500,000, of the Loans, the
Commitments, and the other rights and obligations of such Lender hereunder; provided,
however, that the Company and the Administrative Agent may continue to deal solely and
directly with such Lender in connection with the interest so assigned to an Assignee until (i)
written notice of such assignment, together with payment instructions, addresses and related
information with respect to the Assignee, shall have been given to the Company and the
Administrative Agent by such Lender and the Assignee; (ii) such Lender and its Assignee shall have
delivered to the Company and the Administrative Agent an Assignment and Acceptance in the form of
Exhibit D (“Assignment and Acceptance”) together with any Note or Notes subject to such assignment
and (iii) the assignor Lender or Assignee has paid to the Administrative Agent a processing fee in
the amount of $3,500.00.

          (b) From and after the date that the Administrative Agent notifies the assignor Lender that it
has received an executed Assignment and Acceptance and payment of the above-referenced processing
fee, (i) the Assignee thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, shall
have the rights and obligations of a Lender under the Loan Documents, and (ii) the assignor Lender
shall, to the extent that rights and obligations hereunder and under the other Loan Documents have
been assigned by it pursuant to such

Credit Agreement

64

 

Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Loan Documents.

          (c) Within five (5) Business Days after its receipt of notice by the Administrative Agent that
it has received an executed Assignment and Acceptance and payment of the processing fee, (and
provided that it consents to such assignment in accordance with Subsection 11.08(a)) the
Company shall execute and deliver to the Administrative Agent, new Notes evidencing such Assignee’s
assigned Loans and Commitment and, if the assignor Lender has retained a portion of its Loans and
its Commitment, replacement Notes in the principal amount of the Loans retained by the assignor
Lender (such Notes to be in exchange for, but not in payment of, the Notes held by such Lender,
which shall be cancelled upon receipt of the new or replacement Notes). Immediately upon each
Assignee’s making its processing fee payment under the Assignment and Acceptance, this Agreement
shall be deemed to be amended to the extent, but only to the extent, necessary to reflect the
addition of the Assignee and the resulting adjustment of the Commitments arising therefrom. The
Commitment allocated to each Assignee shall reduce such Commitments of the assigning Lender pro
tanto.

          (d) Any Lender may at any time sell to one or more commercial Lenders or other Persons not
Affiliates of the Company or any Guarantor (a “Participant”) participating interests in any Loans,
the Commitment of that Lender and the other interests of that Lender (the “originating Lender”)
hereunder and under the other Loan Documents; provided, however, that (i) the originating
Lender’s obligations under this Agreement shall remain unchanged, the originating Lender shall
remain a Lender for all purposes hereof and the other Loan Documents to which such originating
Lender is a party, and the Participant may not become a Lender for purposes hereof or for any other
of the Loan Documents, (ii) the originating Lender shall remain solely responsible for the
performance of such obligations, (iii) the Company, the Guarantors and the Administrative Agent
shall continue to deal solely and directly with the originating Lender in connection with the
originating Lender’s rights and obligations under this Agreement and the other Loan Documents, and
(iv) no Lender shall transfer or grant any participating interest under which the Participant has
rights to approve any amendment to, or any consent or waiver with respect to, this Agreement or any
other Loan Document, except to the extent such amendment, consent or waiver would require unanimous
consent of the Lenders. In the case of any such participation, the Participant shall not have any
rights under this Agreement, or any of the other Loan Documents (the Participant’s rights against
the granting Lender in respect of such participation being those set forth in the agreement
creating or evidencing such participation with such Lender), and all amounts payable by the Company
or any Guarantor hereunder shall be determined as if such Lender had not sold such participation;
except that, if amounts outstanding under this Agreement are due and unpaid, or shall have been
declared or shall have become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of set-off in respect of its participating interest
in amounts owing
under this Agreement to the same extent as if the amount of its participating interest were owing
directly to it as a Lender under this Agreement.

          (e) Each Lender agrees to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all information identified as “confidential” or “secret” by the
Company or any Guarantor and provided to it by the Company or any Guarantor, or by the
Administrative Agent on Company’s or any Guarantor’s behalf, under or in connection with this
Agreement or any other Loan Document, and neither it nor any of its Affiliates shall use any such
information other than in connection with or in enforcement of this Agreement and the other Loan
Documents; except to the extent such information (i) was or becomes generally available to the
public other than as a result of disclosure by any Lender or the Administrative Agent or any
Guarantor, or (ii) was or becomes available on a non-confidential basis from a source other than
the Company or any Guarantor, provided that such source is not bound by a confidentiality
agreement with the Company or any Guarantor known to the Lender; provided, however,
that any Lender may disclose such information (A) at the request or pursuant to any requirement of
any Governmental Authority to which the Lender is subject or in connection with an examination of
such Lender by any such authority; (B) pursuant to subpoena or other court process; (C) when
required to do so in accordance with the

Credit Agreement

65

 

provisions of any applicable Requirement of Law; (D) to
the extent reasonably required in connection with any litigation or proceeding to which the
Administrative Agent, any Lender or their respective Affiliates may be party; (E) to the extent
reasonably required in connection with the exercise of any remedy hereunder or under any other Loan
Document; (F) to such Lender’s independent auditors and other professional advisors; (G) to any
Affiliate of such Lender, or to any Participant or Assignee, actual or potential, provided
that such Affiliate, Participant or Assignee agrees to keep such information confidential to
the same extent required of the Lenders hereunder, and (H) as to any Lender, as expressly permitted
under the terms of any other document or agreement regarding confidentiality to which the Company
or any Guarantor is party or is deemed party with such Lender.

          (f) Notwithstanding any other provision in this Agreement, any Lender may at any time create a
security interest in, or pledge, all or any portion of its rights under and interest in this
Agreement and the Notes held by it in favor of any Federal Reserve Lender in accordance with
Regulation A of the FRB or U.S. Treasury Regulation 31 CFR §203.14, and such Federal Reserve Lender
may enforce such pledge or security interest in any manner permitted under applicable law.

     11.09 Interest.

          (a) It is the intention of the parties hereto to comply with applicable usury laws, if any;
accordingly, notwithstanding any provision to the contrary in this Agreement, the Notes or in any
of the other Loan Documents securing the payment hereof or otherwise relating hereto, in no event
shall this Agreement, the Notes or such other Loan Documents require or permit the payment, taking,
reserving, receiving, collection, or charging of any sums constituting interest under applicable
laws which exceed the maximum amount permitted by such laws. If any such excess interest is
called for, contracted for, charged, taken, reserved, or received in connection with the Loans
evidenced by the Notes or in any of the Loan Documents securing the payment thereof or otherwise
relating thereto, or in any communication by the Administrative Agent, the Issuing Lender or the
Lenders or any other Person to the Company or any other Person, or in the event all or part of the
principal or interest thereof shall be prepaid or accelerated, so that under any of such
circumstances or under any other circumstance whatsoever the amount of interest contracted for,
charged, taken, reserved, or received on the amount of principal actually outstanding from time to
time under the Notes or any other Loan Document shall exceed the maximum amount of interest
permitted by applicable usury laws, then in any such event it is agreed as follows: (i) the
provisions of this paragraph shall govern and control, (ii) neither any Company nor any other
Person now or hereafter liable for the payment of the Notes or any Obligation shall be obligated to
pay the amount of such interest to the extent such interest is in excess of the maximum amount of
interest permitted by applicable usury laws, (iii) any such excess which is or has
been received notwithstanding this paragraph shall be credited against the then unpaid principal
balance of the Notes or other Obligations, as applicable, or, if the Notes or other Obligations, as
applicable, have been or would be paid in full, refunded to the Company, and (iv) the provisions of
this Agreement, the Notes and the other Loan Documents securing the payment thereof and otherwise
relating thereto, and any communication to the Company or any other person, shall immediately be
deemed reformed and such excess interest reduced, without the necessity of executing any other
document, to the maximum lawful rate allowed under applicable laws as now or hereafter construed by
courts having jurisdiction hereof or thereof. Without limiting the foregoing, all calculations of
the rate of the interest contracted for, charged, collected, taken, reserved, or received in
connection with the Notes, this Agreement or any other Loan Document which are made for the purpose
of determining whether such rate exceeds the maximum lawful rate shall be made to the extent
permitted by applicable laws by amortizing, prorating, allocating and spreading during the period
of the full term of the Loans or other Obligations, as applicable, including all prior and
subsequent renewals and extensions, all interest at any time contracted for, charged, taken,
collected, reserved, or received. The terms of this paragraph shall be deemed to be incorporated
in every document and communication relating to the Notes, the Loans or any other Loan Document.

Credit Agreement

66

 

     11.10 Indemnity and Subrogation. In addition to all such rights of indemnity and subrogation
as any Guarantor may have under applicable law, the Company agrees that in the event a payment
shall be made by any Guarantor under a Guaranty in respect of a Loan to the Company, the Company
shall indemnify such Guarantor for the full amount of such payment and such Guarantor shall be
subrogated to the rights of the person to whom such payment shall have been made to the extent of
such payment subject to the provisions of the Guaranty executed by such Guarantor. Notwithstanding
any provision of this Agreement to the contrary, all rights of any Guarantor under this Section
11.10 and all other rights of indemnity, contribution or subrogation under applicable law or
otherwise shall be fully subordinated to the indefeasible payment in full of the Obligations, and
no payments may be made in respect of such rights of indemnity, contribution or subrogation until
all the Obligations have been paid in full and all Commitments have expired. No failure on the part
of the Company to make the payments required by this Section (or any other payments required under
applicable law or otherwise) shall in any respect limited the obligations and liabilities required
under applicable law or otherwise) shall in any respect limit the obligations and liability of any
Guarantor with respect to any Guaranty, and such Guarantor shall remain liable for the full amount
of the obligation of such Guarantor under each such Guaranty in accordance therewith.

     11.11 Collateral Matters; Derivative Contracts. The benefit of the Security Documents and of
the provisions of this Agreement relating to any Collateral securing the Indebtedness shall also
extend to and be available to any Lender or any Affiliate of a Lender that is counterparty to any
Derivative Contract with the Company or any Guarantor (including any Derivative Contract between
such Persons in existence prior to the Effective Date) on a pro rata basis in respect of any
obligations of the Company or any Guarantor which arise under any such Derivative Contract;
provided that the applicable counterparty must have provided Administrative Agent written
notice of the existence thereof (such notice to include a summary of the contract date, price,
volumes and other terms of such Derivative Contracts as the Administrative Agent may reasonably
request) and such transaction must not otherwise be prohibited under this Agreement at the time it
was entered into and provided further that if such Lender or Affiliate ceases to be a
Lender (a) its Derivative Contract obligations shall be secured pari passu with the Lenders’
Obligations but only to the extent such counterparty’s obligations arise from transactions entered
into at the time such counterparty was a Lender hereunder or an Affiliate of a Lender hereunder,
and (b) such counterparty shall have no voting rights under any Loan Documents as a result of the
existence of obligations owed to it under any such Derivative Contract. For the avoidance of
doubt, a Person ceases to be a Lender hereunder if (i) pursuant to an assignment, such Person
ceases to have any Commitment, Loans and LC Obligation hereunder or (ii) the Commitments of all of
the Lenders hereunder have been terminated and all principal, interest and other amounts
outstanding under this
Agreement have been paid in full in cash (whether as a result of repayment at maturity,
prepayment in connection with the refinancing of this Agreement or otherwise).

     11.12 USA Patriot Act Notice. Each Lender hereby notifies the Company and the Guarantors 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 Company and the Guarantors, which information includes the name and address of the
Company and the Guarantors and other information that will allow such Lender to identify the
Company and the Guarantors, insofar as it is needed to comply with the Act, in accordance with the
Act. The Company and the Guarantors hereby represent and warrant to Administrative Agent and each
Lender that neither the Company, any Guarantor nor any of their Affiliates is a country, individual
or entity named on the “Specifically Designated National and Blocked Persons” list issued by the
Office of Foreign Asset Control of the Department of the Treasury of the United States of America.

     11.13 Automatic Debits of Fees. With respect to any commitment fee, arrangement fee, letter
of credit fee or other fee, or any other cost or expense (including Attorney Costs) due and payable
to the Administrative Agent or any Lender under the Loan Documents, each of the Company and the
Guarantors hereby irrevocably authorizes the Administrative Agent, after giving reasonable prior
notice to the Company

Credit Agreement

67

 

or the applicable Guarantor, to debit any deposit account of the Company or
such Guarantor with the Administrative Agent in an amount such that the aggregate amount debited
from all such deposit accounts does not exceed such fee or other cost or expense. If there are
insufficient funds in such deposit accounts to cover the amount of the fee or other cost or expense
then due, such debits will be reversed (in whole or in part, in the Administrative Agent’s sole
discretion) and such amount not debited shall be deemed to be unpaid. No such debit under this
Section shall be deemed a set-off.

     11.14 Notification of Addresses, Lending Offices, Etc. Each Lender shall notify the
Administrative Agent in writing of any changes in the address to which notices to the Lender should
be directed, of addresses of any Lending Office, of payment instructions in respect of all payments
to be made to it hereunder and of such other administrative information as the Administrative Agent
shall reasonably request.

     11.15 Counterparts. This Agreement may be executed in any number of separate counterparts,
each of which, when so executed, shall be deemed an original, and all of said counterparts taken
together shall be deemed to constitute but one and the same instrument.

     11.16 Severability. The illegality or unenforceability of any provision of this Agreement or
any instrument or agreement required hereunder shall not in any way affect or impair the legality
or enforceability of the remaining provisions of this Agreement or any instrument or agreement
required hereunder.

     11.17 No Third Parties Benefited. This Agreement is made and entered into for the sole
protection and legal benefit of the Company, the Guarantors, the Lenders, the Administrative Agent
and the Agent-Related Persons, and their permitted successors and assigns, and no other Person
shall be a direct or indirect legal beneficiary of, or have any direct or indirect cause of action
or claim in connection with, this Agreement or any of the other Loan Documents.

     11.18 Governing Law, Jurisdiction and Waiver of Jury Trial. The provisions of Section 11.19
hereof shall govern the resolution of any Dispute (as such term is defined in such Section 11.19).
If, however, the provisions of Section 11.19 are not invoked as therein provided, the following
provisions shall apply:

          (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAW OF THE STATE OF NEW YORK AND APPLICABLE FEDERAL LAW; AND THE ADMINISTRATIVE AGENT AND THE
LENDERS SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

          (b) THE COMPANY AND EACH OF THE GUARANTORS IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS IN
ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT BY THE
MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT ITS ADDRESS
SET FORTH IN SCHEDULE 11.02. SUCH SERVICE TO BECOME EFFECTIVE TEN DAYS AFTER SUCH MAILING.
NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY LENDER TO SERVE PROCESS IN
ANY OTHER MANNER PERMITTED BY LAW.

MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES FOR THE SOUTHERN
DISTRICT OF NEW YORK AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE COMPANY AND EACH
GUARANTOR CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF

IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING 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 ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF

SUCH LEGAL ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL,
POSTAGE PREPAID, TO IT AT ITS ADDRESS FOR NOTICES SET FORTH HEREIN, SUCH SERVICE TO BECOME

ADMINISTRATIVE AGENT EACH AGREES THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT
TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR
RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION,
COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR
ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO
THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

entire agreement and understanding among the Company, the Guarantors, the Lenders and the
Administrative Agent, and supersedes all prior or contemporaneous agreements and understandings of
such Persons, verbal or written, relating to the subject matter hereof and thereof.

DOCUMENTS EXECUTED IN CONNECTION HEREWITH, REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND

Exhibit 10.16

INDEMNIFICATION AGREEMENT

     THIS AGREEMENT is made as of the 1st day of February, 2008,

BETWEEN:

IVANHOE ENERGY INC., a corporation governed by the Yukon Business Corporations Act
and having its corporate offices at Suite 654 – 999 Canada Place, Vancouver, B.C.
V6C 3E1

(the “Corporation”)

- and -

[Name of Director/Officer], whose address is [Address of Director/Officer]

(the “Indemnified Party”)

RECITALS:

	A.	 	The Yukon Business Corporations Act (the “YBCA”) permits the Corporation to indemnify
individuals who are or were directors and officers of the Corporation, or who act or acted at
the Corporation’s request as directors or officers or in a similar capacity of an Other Entity
(as defined herein);
	 
	B.	 	It is generally agreed that, because of the uncertainties in relying upon an indemnity in a
corporation’s bylaws and because liability insurance may afford the parties inadequate
protection, it is desirable for directors and officers to obtain a contractual indemnity from
the corporations they serve;
	 
	C.	 	It is in the best interests of the Corporation to attract and retain responsible and capable
directors and officers, and the entering into of an agreement containing broad indemnification
provisions of the kind contained in this Agreement is of vital importance to achieving these
goals. Accordingly, the Corporation and the Indemnified Party wish to enter into this
Agreement, and in so doing affirm that they intend that all the provisions of this Agreement
be given legal effect to the full extent not prohibited by applicable law; and
	 
	D.	 	The Corporation has obtained policies of insurance for the benefit of the Indemnified Party,
which, subject to section 12.3, will be maintained in full force and effect.

              NOW THEREFORE in consideration of the sum of $1.00 now given by the Indemnified Party to the
Corporation, the Indemnified Party’s agreement to become or continue as a Director or Officer of
the Corporation, the mutual covenants and agreements contained in this Agreement and other good and
valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the parties
agree as follows:

	1.	 	For the purposes of this Agreement:

	 	1.1	 	“Agreement” means this Indemnification Agreement;

 

 

- 2 -

	 	1.2	 	“Director” and “Officer”, respectively, means an individual who is or was a
director or an officer of the Corporation, as the case may be, or who acts or acted, at
the Corporation’s request, as a director or an officer of or in a similar capacity in
respect of one or more Other Entities, and the phrase “Director and Officer” means an
individual who is or was either a Director or an Officer, or both. For greater
certainty, serving as a director includes serving as a member of one or more committees
of the board of directors;
	 
	 	1.3	 	“Costs” shall include:

	 	1.3.1	 	subject to section 11, an amount paid to settle an action or
satisfy a judgment, except in respect of an action to which section 6 is
applicable unless and until approval of the Supreme Court of the Yukon
Territory has been obtained;
	 
	 	1.3.2	 	a fine, penalty, levy, charge, award, damages, settlement
payment, compensation or financial imposition paid to or imposed by any
domestic or foreign government (federal, provincial, municipal or otherwise) or
to any regulatory authority, agency, commission or board of any domestic or
foreign government, or imposed by any court or any other law, regulation or
rule-making entity having jurisdiction in the relevant circumstances
(collectively, a “Governmental Authority”), including as a result of a breach
or alleged breach of any statutory or common law duty imposed on directors or
officers or of any law, statute, rule or regulation or any provision of the
articles, by-laws or any resolution of the Corporation or an Other Entity;
	 
	 	1.3.3	 	an amount paid to satisfy a liability arising as a result of
the failure of the Corporation or an Other Entity to pay wages, vacation pay
and any other amounts that may be owing to employees or to make contributions
that may be required to be made to any pension plan, retirement income plan or
other benefit plan for employees or to remit to any Governmental Authority
payroll deductions, income taxes or other taxes, or any other amounts payable
by the Corporation or an Other Entity; and
	 
	 	1.3.4	 	an amount equal to the per diem meeting fee paid by the
Corporation to its directors at such time, for each day spent by the
Indemnified Party in dealing with, responding to or assisting the Corporation
with the resolution of any Proceeding relating to the Indemnified Party. The
amount of the fee shall be pro rated for less than any full day spent, and
shall not be paid in respect of meetings of the Board of Directors or a
committee thereof attended by the Indemnified Party for which he is so
compensated by the Corporation;

	 	1.4	 	“Expenses” shall include all expenses incurred by or on behalf of the
Indemnified Party in connection with any Proceeding, and shall include, without
limiting the generality of the foregoing, legal costs on a solicitor and his own client
basis, together with retainers, court costs, transcripts, fees of experts, witness
fees, travel

 

 

- 3 -

	 	 	 	expenses, duplicating costs, printing and binding costs, telephone and facsimile
charges, postage, delivery service fees and all other disbursements, costs, charges
and expenses incurred by or on behalf of the Indemnified Party in connection with
such Proceeding, including those incurred in interpreting, applying and enforcing
the Indemnified Party’s rights under this Agreement;
	 
	 	1.5	 	The Indemnified Party shall be considered to be “involved” in any Proceeding if
the Indemnified Party has any participation whatsoever in such Proceeding, including
merely as a witness or a person providing information;
	 
	 	1.6	 	“Other Entity” shall include a body corporate, partnership, joint venture,
association, employee benefit plan, trust or other enterprise or organization of which
the Corporation is or was a shareholder or creditor and for which an individual acts or
acted as a director or officer or in a similar capacity at the request of the
Corporation, and includes an entity that becomes an Other Entity subsequent to the date
hereof;
	 
	 	1.7	 	“Proceeding” shall include a claim, demand, suit, action, proceeding or
investigation (civil, criminal, regulatory, administrative, arbitral or other), whether
anticipated, threatened, pending, commenced, continuing or completed, and any appeal or
appeals therefrom, and any other circumstance or situation, in respect of which the
Indemnified Party reasonably requires legal advice or representation concerning the
actual, possible or anticipated imposition of Costs or Expenses upon the Indemnified
Party and arising at any time in whole or in part, directly or indirectly, from the
Indemnified Party being or having been a Director or Officer, notwithstanding that the
Indemnified Party denies liability for the possible Costs or Expenses or that the
possible attempt to impose such Costs or Expenses is without merit;
	 
	 	1.8	 	Unless the context otherwise requires, words importing the singular include the
plural and vice versa and words importing gender include all genders; and
	 
	 	1.9	 	Unless otherwise indicated, references to sections are to sections in this
Agreement.

	2.	 	Subject to sections 3 and 4, the Corporation agrees to the fullest extent not prohibited by
law, promptly upon demand, to indemnify and save harmless the Indemnified Party and his heirs
and legal representatives:

	 	2.1	 	from and against all Costs, charges and Expenses incurred by the Indemnified
Party in respect of any Proceeding in which the Indemnified Party is involved or is
subject by reason of being or having been a Director and Officer; and
	 
	 	2.2	 	from and against all liabilities, damages, Costs, charges and Expenses
whatsoever that the Indemnified Party may sustain or incur as a result of serving as a
Director and Officer in respect of any act, matter, deed or thing whatsoever made,
done, committed, permitted or acquiesced in by the Indemnified Party as a Director and
Officer, whether before or after the effective date of this Agreement.

 

 

- 4 -

	3.	 	The Corporation will indemnify the Indemnified Party under section 2 in all circumstances in
which indemnification of a director or officer is permitted by the YBCA, which at the date
hereof provides that the Corporation may indemnify the Indemnified Party if the Indemnified
Party:

	 	3.1	 	acted honestly and in good faith with a view to the best interests of the
Corporation; and
	 
	 	3.2	 	in the case of a criminal or administrative Proceeding that is enforced by a
monetary penalty, the Indemnified Party had reasonable grounds for believing that the
Indemnified Party’s conduct was lawful.

	 	 	The applicable provisions of the YBCA permitting indemnification are referred to in this
Agreement as the “Standards of Conduct”.
	 
	4.	 	Upon the Indemnified Party becoming aware of any Proceeding which may give rise to
indemnification under this Agreement, the Indemnified Party shall give written notice to the
Corporation, directed to its Chief Executive Officer or President or Chief Financial Officer,
as soon as is practicable, provided however that failure to give notice in a timely fashion
shall not disentitle the Indemnified Party to indemnification unless, and then only to the
extent that, the Corporation suffers actual prejudice by reason of the delay.
	 
	5.	 	The Corporation may conduct any investigation it considers appropriate of any Proceeding of
which it receives notice under section 4, and shall pay all costs of that investigation.
	 
	6.	 	In respect of an action by or on behalf of the Corporation or an Other Entity to procure a
judgment in its favour to which the Indemnified Party is made a party by reason of being or
having been a Director and Officer of the Corporation or the Other Entity, the Corporation
shall:

	 	(a)	 	first determine, acting reasonably, whether the Director or Officer seeking
indemnification has met the Standards of Conduct;
	 
	 	(b)	 	if satisfied that the Standards of Conduct have been met in accordance with (a)
above, apply forthwith to the Supreme Court of the Yukon Territory pursuant to section
126(2) of the YBCA for the approval of the court to indemnify such Director or Officer
under this Agreement in connection with such action, including the making of Expense
Advances under section 7; and
	 
	 	(c)	 	notwithstanding the foregoing, indemnify the Director or Officer seeking
indemnification only after such Director or Officer has applied to and received an
order approving such indemnification from the Supreme Court of the Yukon Territory
under section 126(3) of the YBCA.

	7.	 	The parties wish to facilitate the payment by the Indemnified Party of ongoing costs in
connection with matters for which indemnification under this Agreement is provided.
Accordingly, the parties agree as follows:

 

 

- 5 -

	 	7.1	 	the Indemnified Party has the right to incur Expenses for the purpose of
protecting his interests fully and effectively in any Proceeding;
	 
	 	7.2	 	the Corporation shall, promptly upon demand, make advances (“Expense Advances”)
to the Indemnified Party for any Costs and Expenses for which the Indemnified Party
seeks indemnification under this Agreement at any time after the inception of
Proceedings and up to the final disposition of the relevant Proceeding. In connection
with such demand, the Indemnified Party shall provide the Corporation with: (a) a
written affirmation of the Indemnified Party’s good faith belief that the Indemnified
Party is entitled to indemnification hereunder, together with particulars of the Costs
and Expenses to be covered by the proposed Expense Advance; and (b) a written
undertaking to repay Expense Advances in the circumstances set forth in section 7.3
hereof; and
	 
	 	7.3	 	the Indemnified Party shall repay to the Corporation, upon demand, Expense
Advances (a) if and to the extent that it is determined by a court of competent
jurisdiction that the Indemnified Party is not entitled to indemnification hereunder,
(b) if and to the extent that the Corporation has fully performed its obligations to
the Indemnified Party under this Agreement with respect to the advancement of Expense
Advances and other matters bearing on the ability of the Indemnified Party to protect
his interests fully and effectively in the Proceeding, and (c) subject to any right of
counterclaim or set off in favour of the Indemnified Party.

	8.	 	Subject to section 9, the Indemnified Party has the right to appoint and instruct independent
counsel to act on his behalf with respect to a Proceeding and all Expenses incurred by or in
connection with such appointment and engagement shall be indemnified, advanced, paid or
reimbursed, as the case may be by the Corporation as contemplated by sections 2 and 7.
	 
	9.	 	The Corporation shall be entitled to participate, at its own expense, in the defence of the
Indemnified Party in any Proceeding. If the Corporation so elects after receipt of notice of a
Proceeding, or the Indemnified Party in that notice so directs, the Corporation shall assume
control of the negotiation, settlement or defence of the Proceeding, in which case the defence
shall be conducted by experienced and competent counsel chosen by the Corporation and
reasonably satisfactory to the Indemnified Party. If the Corporation elects to assume control
of the defence, the Indemnified Party shall have the right to participate in the negotiation,
settlement or defence of the Proceeding and to retain counsel to act on the Indemnified
Party’s behalf, and the fees and disbursements of that counsel shall be paid by the
Corporation. Notwithstanding the foregoing provisions, the Indemnified Party shall have the
right, at the Corporation’s expense, to separately retain counsel of such Indemnified Party’s
choice, in respect of the defence of any Proceeding in respect of which the Corporation has
elected to assume control if: (i) the employment of such counsel has been authorized by the
Corporation; (ii) the Corporation has not assumed the defence and employed competent and
experienced counsel therefor promptly after receiving notice of such Proceeding; or (iii)
counsel retained by the Corporation or the Indemnified Party has advised the Indemnified Party
that representation of both parties by the same counsel would be inappropriate for any reason,
including for the

 

 

- 6 -

	 	 	reason that there may be legal defences available to the Indemnified Party which are
different from or in addition to those available to the Corporation (in which event and to
that extent, the Corporation shall not have the right to assume or direct the defence on
such Indemnified Party’s behalf) or that there is a conflict of interest between the
Corporation and the Indemnified Party or the subject matter of the Proceeding may not fall
within the indemnity set forth herein (in any of which events the Corporation shall not have
the right to assume or direct the defence on such Indemnified Party’s behalf), provided that
the Corporation shall not be responsible for the fees or expenses of more than one legal
firm acting on behalf of the Indemnified Party in any single jurisdiction at any one time.
The Indemnified Party and the Corporation shall cooperate fully with each other and their
respective counsel in the investigation related to, and defence of, any Proceeding and shall
make available to each other all relevant books, records, documents and files and shall
otherwise use their best efforts to assist each other’s counsel to conduct a proper and
adequate defence.
	 
	10.	 	The indemnities in section 2 shall not apply in respect of any Proceeding initiated by the
Indemnified Party:

	 	10.1	 	against the Corporation or an Other Entity, unless it is brought to establish
or enforce any right under this Agreement;
	 
	 	10.2	 	against any Director or Officer unless the Corporation or the Other Entity, as
the case may be, has joined in or consented to the initiation of such Proceeding; or
	 
	 	10.3	 	against any other corporation, partnership, trust, joint venture,
unincorporated entity or person, unless it is a counterclaim in such Proceeding.

	11.	 	The parties wish to encourage the settlement of any Proceeding. Accordingly, the parties
agree as follows:

	 	11.1	 	the Corporation may, with the prior written consent of the Indemnified Party
(which consent shall not be unreasonably withheld or delayed), enter into an agreement
to settle any Proceeding;
	 
	 	11.2	 	no admission of liability and no settlement of any Proceeding shall be made by
the Corporation without the prior written consent of the Indemnified Party affected
(which consent shall not be unreasonably withheld or delayed) unless such settlement
includes an unconditional general release of the Indemnified Party from any and all
liabilities arising out of such Proceeding without any admission of negligence,
misconduct, liability or responsibility by the Indemnified Party;
	 
	 	11.3	 	the Corporation shall not be liable for any settlement of any Proceeding
effected without its prior written consent (which consent shall not be unreasonably
withheld or delayed);
	 
	 	11.4	 	the Indemnified Party shall have the right to negotiate a settlement in respect
of any Proceeding, provided that if the Corporation, acting reasonably, declines to
approve the settlement, the Indemnified Party shall pay any compensation or other

 

 

- 7 -

	 	 	 	payment to be made under the settlement and the costs of negotiating and
implementing the settlement, and shall not seek indemnity from the Corporation in
respect of such compensation, payment or costs; and
	 
	 	11.5	 	the settlement of a Proceeding shall not create a presumption that the
Indemnified Party did not meet or would not have met the Standards of Conduct.

	12.	 	The Corporation shall ensure that all liabilities of the Corporation under this Agreement and
all of the actions of the Indemnified Party which fall within the Standards of Conduct are at
all times covered by directors’ and officers’ liability insurance maintained by the
Corporation in favour of the Corporation and the Indemnified Party with a responsible insurer.
In this regard, the parties agree that:

	 	12.1	 	the responsibility for obtaining, maintaining and obtaining for the benefit of
the Indemnified Party such directors’ and officers’ liability insurance shall rest with
the Corporation and shall be implemented by a senior manager of the Corporation who
shall involve an insurance broker or other person having expertise and experience in
directors’ and officers’ liability insurance;
	 
	 	12.2	 	the Corporation shall provide to the Indemnified Party a summary of the
material terms of each policy of insurance providing the coverages contemplated by this
section 12 promptly after such coverage is obtained, and shall promptly notify the
Indemnified Party if the insurer cancels or refuses to renew such coverage (or any part
of such coverage);
	 
	 	12.3	 	such insurance coverage need not be obtained by the Corporation only if the
coverage is not available from responsible insurers, or is available from one or more
responsible insurers but at a cost which, in the opinion of the Corporation, acting
reasonably and taking into account the financial condition and size of the Corporation,
the nature of its business and the extent of the risks of personal liability to which
the Indemnified Party is or may be subject, is grossly excessive, in which case the
Indemnified Party may elect to terminate his position as a Director of the Corporation
but the provisions of this Agreement shall remain in full force and effect for his
benefit following such termination;
	 
	 	12.4	 	the Corporation shall not do any act or thing (including changing insurers), or
fail to do any act or thing, that could cause or result in a denial of insurance
coverage or of any claim under such coverage;
	 
	 	12.5	 	the Corporation shall give prompt notice of the commencement of any Proceeding
to the insurers on the directors’ and officers’ liability insurance maintained by the
Corporation, if any, in accordance with the procedures set forth in the respective
policies. The Corporation shall thereafter take all necessary action to cause such
insurers to pay, on behalf of the Indemnified Party, all amounts payable as a result of
such Proceedings in accordance with the terms of such policies; and
	 
	 	12.6	 	in the event of any reduction in, or cancellation of, the directors’ and
officers’ liability insurance maintained by the Corporation, the Indemnified Party’s
rights

 

 

- 8 -

	 	 	 	to Expense Advances and indemnification shall not be affected by such reduction or
cancellation.

	13.	 	Should any payment made pursuant to this Agreement, including the payment of insurance
premiums or any payment made by an insurer under an insurance policy, be deemed to constitute
a taxable benefit or otherwise be or become subject to any tax or levy, then the Corporation
shall pay any amount as may be necessary to ensure that the amount received by or on behalf of
the Indemnified Party, after the payment of or withholding for such tax, fully reimburses the
Indemnified Party for the actual cost, expense or liability incurred by or on behalf of the
Indemnified Party.
	 
	14.	 	Notwithstanding the date of execution of this Agreement, this Agreement shall be effective as
of the date on which the Indemnified Party first became a Director or Officer, except that the
rights of the Indemnified Party with respect of insurance coverage are as stated in Section 12
of this Agreement.
	 
	15.	 	This Agreement is to be interpreted broadly and purposively so as to provide the Indemnified
Party with the broadest possible entitlement to Expense Advances and to indemnification except
as and to the extent prohibited by applicable law as presently in effect or as changed after
the date of this Agreement, whether by statute or judicial decision.
	 
	16.	 	Each of the provisions contained in this Agreement is distinct and severable and a
declaration of invalidity or unenforceability of any such provision or part thereof by a court
of competent jurisdiction shall not affect the validity or enforceability of any other
provision hereof. Should the content, or the application sought by the Indemnified Party of
any of the provisions of this Agreement, be found to exceed the scope of indemnification
lawfully available to the Indemnified Party from the Corporation, the affected provision is to
be read down so as to be interpreted or applied with the smallest reduction in scope
consistent with the applicable law and with the purpose of this Agreement, including this
section 16. To the extent permitted by applicable law, the parties waive any provision of
applicable law which renders any provision of this Agreement invalid or unenforceable in any
respect.
	 
	17.	 	The Indemnified Party’s right to indemnification under this Agreement is in addition to, and
not in substitution for, any rights of indemnification in favour of the Indemnified Party
pursuant to any provision of the Articles of Incorporation or Bylaws of the Corporation, any
agreement, vote of stockholders or disinterested directors, applicable law or otherwise. No
amendment, termination or repeal of any provision of the Articles of Incorporation or Bylaws
of the Corporation, or any respective successors thereto, shall affect or diminish in any way
the rights of the Indemnified Party to indemnification, or the obligations of the Corporation,
arising under this Agreement, whether the alleged actions or conduct of the Indemnified Party
giving rise to the necessity of such indemnification arose before or after any such amendment,
termination or repeal.
	 
	18.	 	It being the desire of the parties, notwithstanding the restrictive provisions of the
Limitation of Actions Act (Yukon Territory), the Limitation Act, 1996 (British Columbia) or
any successor legislation, or any similar legislation of any other jurisdiction which

 

 

- 9 -

	 	 	may be applicable in any action brought by a Director or Officer pursuant to this Agreement
(the “Limitation Acts”), to provide for the equivalent of a limitation period of six years
from the conclusion of a Proceeding, the parties:

	 	(a)	 	acknowledge that, in the Limitation Acts, the limitation period currently
prescribed for certain Proceedings under this Agreement by an Indemnified Party or the
Corporation, or any person claiming in right thereof, may be two years from the day on
which the claim was discovered within the meaning of the Limitation Acts; and
	 
	 	(b)	 	agree that if and when:

	 	(i)	 	it is lawful for the parties to enter into an agreement to
vary, exclude or waive the limitation period otherwise applicable under a
Limitation Act, or
	 
	 	(ii)	 	a Limitation Act is amended to prescribe a longer limitation
period, then:

	 	 	 	this Agreement will be deemed to have been amended, with effect from the date of the
relevant change, clarification, or amendment, to provide that any Proceeding in
respect of a claim under this Agreement must be commenced within six years from the
conclusion of the pertinent Proceeding, or such longer period as may be prescribed
or permitted by statute. For greater certainty, this provision shall apply to any
claim which would, prior to such date, have been statute-barred but where the
pertinent Proceeding was concluded less than six years before such date, and for
that purpose the parties agree that in such circumstances the Corporation shall not
plead and does hereby waive any limitation defence which would otherwise have been
available to it in an action brought by a Director or Officer under this Agreement.

	19.	 	Except as expressly provided in this Agreement, no amendment or waiver of this Agreement
shall be binding unless executed in writing by the party to be bound thereby. No waiver of any
provision of this Agreement shall constitute a waiver of any other provision hereof (whether
or not similar), nor shall any waiver of any provision of this Agreement constitute a
continuing waiver unless otherwise expressly provided.
	 
	20.	 	The obligations of the Corporation under this Agreement shall survive its termination and
continue in full force after the Indemnified Party ceases to be a Director or Officer of the
Corporation.
	 
	21.	 	This Agreement shall enure to the benefit of the Indemnified Party and the Indemnified
Party’s heirs, personal and legal representatives, executors and administrators and shall be
binding upon the Corporation and its successors (including any direct or indirect successor by
merger, consolidation or operation of law). This Agreement shall not otherwise be assignable
by the Corporation or the Indemnified Party.
	 
	22.	 	This Agreement shall be governed by and construed in accordance with the laws of the Yukon
Territory and the laws of Canada applicable therein.
