agreed that the ORRI shall be and remain, at all times, prior and superior to
the lien of this Deed of Trust.

                 Particular Covenants and Warranties of Trustor

2.1 Certain Representations and Warranties. Trustor represents and warrants to
the Trustee, the Agent and the other Secured Parties that, as of the date of
this Mortgage, (a) the Oil and Gas Properties described in Exhibit A hereto are
valid, subsisting leases, superior and paramount to all other Oil and Gas
Properties respecting the properties to which they pertain except where the
failure hereunder could not reasonably be expected to have a Material Adverse
Effect, (b) all producing wells located on the lands described in Exhibit A have
been drilled, operated and produced in conformity with all applicable laws,
statutes, rules or regulations, except where the failure hereunder could not
reasonably be expected to have a Material Adverse Effect, and are subject to no
penalties on account of past production which could reasonably be expected to
have a Material Adverse Effect, and such wells are in fact bottomed under and
are producing from, and the well bores are wholly within, the lands described in
Exhibit A except where the failure hereunder could not reasonably be expected to
have a Material Adverse Effect, (c) the Mortgaged Properties are free from all
encumbrances or liens whatsoever, except as may be specifically set forth in
Exhibit A or as permitted by Section 6.02 of the Credit Agreement, and (d) the
cover page to this Deed of Trust lists the correct legal name of Trustor and
Trustor is not now known by any trade name. Trustor will warrant and forever
defend the Mortgaged Properties unto the Trustee or the Agent, as applicable,
against every person whomsoever lawfully claiming the same or any part thereof
(subject, however, to the Liens permitted by Section 6.02 of the Credit
Agreement), and Trustor will maintain and preserve the Lien hereby created so
long as any of the Secured Obligations remains unpaid.

2.2 Operation of the Mortgaged Properties. So long as the Secured Obligations or

the Mortgaged Properties, Trustor shall, at Trustor's own expense:

     A.   Cause to be paid, promptly as and when due and payable, all rentals
          and royalties (including shut-in royalties) payable in respect of the
          Mortgaged Properties, including payments into suspense accounts if
          appropriate, and all expenses incurred in or arising from the
          operation or development of the Mortgaged Properties except for those
          amounts being contested by Trustor in good faith in such manner as not
          to jeopardize the rights of the Trustee, the Agent and the other
          Secured Parties in and to the Mortgaged Properties; and

     B.   Notwithstanding anything in this Section to the contrary, as to any of
          the Mortgaged Properties which is a working interest operated by a
          person other than Trustor, Trustor agrees to take all such action and
          to exercise all rights as are commercially feasible and reasonably
          available to Trustor (including, but not limited to, all rights of
          Trustor under any operating agreement) to cause the

                                     Page 11

<page>

          operator of such property to comply with the covenants and agreements
          contained herein.

2.3 Recording, etc. Trustor will promptly, and at Trustor's expense, record,
register, deposit and file this Deed of Trust and every other instrument in
addition or supplemental hereto in such offices and places and at such times and
as often as may be reasonably necessary to preserve, protect and renew the Lien
hereof as a first lien on and prior perfected security interest, subject to
Liens permitted by Section 6.02 of the Credit Agreement, in real or personal
property, as the case may be, and the rights and remedies of the Trustee, the
Agent and the other Secured Parties, and otherwise will do and observe all
things or matters reasonably necessary or expedient to be done or observed by
reason of any law or regulation of any state or of the United States of America
or of any other Governmental Authority, for the purpose of effectively creating,
maintaining and preserving the Lien on and in the Mortgaged Properties.

                                   ARTICLE III
                       Assignment of Production and Leases

3.1 Assignment. As further security for the payment of the Secured Obligations,
Trustor hereby transfers, assigns, warrants and conveys to the Agent, for itself
and as agent for the Secured Parties, effective as of the Closing Date, at 7:00
A.M., local time, all Hydrocarbons which are thereafter produced from and which
accrue to the Mortgaged Properties (the "Production"), and all Proceeds
therefrom. During the continuance of an Event of Default, Trustor authorizes and
empowers the Agent to demand, collect, receive and receipt for all Production
and Proceeds. TRUSTOR IRREVOCABLY APPOINTS THE AGENT AS THE AGENT AND
ATTORNEY-IN-FACT OF TRUSTOR, FOR THE PURPOSE OF EXECUTING ANY TRANSFER ORDERS,
PAYMENT ORDERS, DIVISION ORDERS, RECEIPTS, RELEASES OR OTHER INSTRUMENTS
(COLLECTIVELY, "RECEIPTS") THAT THE AGENT DEEMS REASONABLY NECESSARY IN ORDER
FOR THE AGENT TO DEMAND, COLLECT, RECEIVE AND RECEIPT FOR PRODUCTION AND
PROCEEDS DURING THE CONTINUANCE OF AN EVENT OF DEFAULT. In addition, Trustor
agrees that, upon the Agent's request, Trustor shall promptly execute and
deliver to the Agent such Receipts as the Agent may deem reasonably necessary in
connection with the payment and delivery directly to the Agent of all Production
and Proceeds and to effectuate the purposes of this paragraph. All parties
producing, purchasing or receiving any Production or having Production or
Proceeds in their possession for which they or others are accountable to the
Agent by virtue of the provisions of this Article III are authorized and
directed to treat and regard the Agent as the assignee and transferee of Trustor
and entitled in Trustor's place and stead to receive Production and Proceeds;
and said parties and each of them shall be fully protected in so treating and
regarding the Agent and shall be under no obligation to see to the application
by the Agent of any Production or Proceeds received by it. Notwithstanding the
foregoing, the Agent, for itself and as agent for the Secured Parties, has
agreed not to exercise its right to directly receive delivery of Production and
payment of Proceeds immediately. Rather, each party producing, purchasing or
receiving Production may continue to make such deliveries or

                                     Page 12

<page>

payments to Trustor until such time as such party has received notice from the
Agent that an Event of Default has occurred and is continuing and that such
party is directed to make delivery or payment directly to the Agent.

3.2 Assignment of Leases. Trustor absolutely and unconditionally assigns,
transfers, sets over and conveys to Beneficiary the Mortgaged Properties,
including, without limitation, the Oil and Gas Properties and all existing and
future leases, subleases, tenancies, subtenancies, licenses, contracts, contract
rights, and occupancy and all other agreements, whether or not in writing,
affecting the use, enjoyment or occupancy of the Mortgaged Properties, together
with any extension, renewal, or replacement of the same. This assignment
includes all present and future leases and present and future agreements and is
effective without further or supplemental assignment, except as may be required
by any Governmental Authority.

3.3 License to Collect. Beneficiary hereby grants to Trustor an exclusive
license, revocable upon occurrence of an Event of Default, to possess, use, and
enjoy the Mortgaged Properties and to collect and retain the proceeds of and
from the Mortgaged Properties, unless and until an Event of Default occurs.

3.4 Application of Proceeds. All payments received by the Agent pursuant to this
Article 111 shall be applied in the manner set forth in Section 4.01 of the
Intercreditor Agreement.

3.5 No Liability of the Agent in Collecting. The Agent is hereby absolved from
all liability for failure to enforce collection of any proceeds so assigned (and
no such failure shall be deemed to be a waiver of any right of the Agent under
this Article) and from all other responsibility in connection therewith, except
the responsibility to account to Trustor for funds actually received.

3.6 Assignment Not a Restriction on the Agent's Rights. Nothing herein contained
shall detract from or limit the absolute obligation of Trustor to make payment
of the Secured Obligations regardless of whether the proceeds assigned by this
Article would be sufficient to pay the same, and the rights under this Article
shall be in addition to all other security now or hereafter existing to secure
the payment of the Secured Obligations.

3.7 Status of Assignment. Notwithstanding the other provisions of this Article
and in addition to the other rights hereunder, the Trustee, the Agent or any
receiver appointed in judicial proceedings for the enforcement of this Deed of
Trust shall have the right to receive all of the Production and Proceeds after
the Secured Obligations have been declared due and payable and to apply all of
said proceeds as provided in Section 3.4 hereof. Upon any sale of the Mortgaged
Properties or any part thereof pursuant to Article V. the Hydrocarbons
thereafter produced from the property so sold, and the proceeds therefrom, shall
be included in such sale and shall pass to the purchaser free and clear of the
assignment contained in this Article.

3.8 Indemnity. Trustor shall indemnify the Trustee, the Agent and the other
Secured Parties, and all of the Related Parties of any of the foregoing Persons
(each such Person being called an

                                     Page 13

<page>

"Indemnitee") against, and hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including the fees,
charges and disbursements of any counsel for any Indemnitee, incurred by or
asserted against any Indemnitee arising out of, in connection with, or as a
result of, (i) the assertion, either before or after the payment in full of the
Secured Obligations, that any Indemnitee received Production or Proceeds claimed
by third persons, or (ii) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on
contract, tort or any other theory and regardless of whether any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or wilful
misconduct of such Indemnitee (IT BEING UNDERSTOOD THAT IT IS THE INTENTION OF
THE PARTIES HERETO THAT, EXCEPT AS PROVIDED BY LAW TO THE CONTRARY, EACH OF THE
AGENTS BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS
NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY,
ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL). All amounts due under this
Section 3.8 shall be payable not later than thirty (30) days after written
demand therefor. The obligations of Trustor as herein set forth in this Section
3.8 shall survive the release, termination, foreclosure or assignment of this
Deed of Trust or any sale hereunder.

3.9 Rights Under Statutes. Trustor hereby appoints the Agent as its
attorney-in-fact to pursue any and all lien rights of Trustor to liens and
security interests in the Mortgaged Properties securing payment of Production
and Proceeds attributable to the Mortgaged Properties, including, but not
limited to, those liens and security interests provided for by AS 45.29.319.
Trustor further hereby assigns to the Agent any and all such liens, security
interests, financing statements, or similar interests of Trustor attributable to
its interests in the Mortgaged Properties and Production and Proceeds therefrom
arising under or created by said statutory provision, judicial decision, or
otherwise.

                                   ARTICLE IV
                                Events of Default

4.1 Events of Default Hereunder. The occurrence of an Event of Default under the
terms and provisions of the Credit Agreement and the continuance of such Event
of Default for the applicable period of grace, if any, shall be an "Event of
Default" hereunder.

                                    ARTICLE V
                           Enforcement of the Security

5.1  Power of Sale and Foreclosure of Real Property Constituting a Part of the
     Mortgaged Properties.

     During the continuation of an Event of Default, the Trustee shall have the
right and power to sell, to the extent permitted by law, at one or more sales,
as an entirety or in parcels, as it may elect, the real property constituting a
part of the Deed of Trust Mortgaged Properties, at such place or places and
otherwise in such manner and upon such notice as may be required by law, or, in
the absence of any such requirement, as the Trustee may deem appropriate, and to
make conveyance to the purchaser or purchasers, without any covenant or
warranty, express or implied. The Trustee may postpone the sale of all or any
portion of such real property by public announcement at the time and place of
such sale, and from time to time thereafter may further postpone such sale by
public announcement made at the time of sale fixed by the preceding
postponement. The right of sale hereunder shall not be exhausted by one or any
sale, and the Trustee may make other and successive sales until ail of the trust
estate be legally sold.

     Notice of any such sale shall be given as required by law, after the
completion of which the Trustee, without demand on Trustor, shall sell said
portion of the Deed of Trust Mortgaged Properties in Anchorage, Alaska (or at
such location as may be permitted by law if Anchorage is not permitted to be the
point of sale), at the place provided by law at the time fixed by the Trustee in
said notice of sale, either as a whole or in separate parcels and in such order
as it may determine, at public auction to the highest and best cash bidder. In
conformity with Section 5.6 hereof, the Agent shall have the right to make an
offset bid without cash in an amount not in excess of the balance owed by
Trustor at the time of the sale, including any sums expended by the Agent and
the Trustee under this Deed of Trust with interest, attorneys' fees, and costs
of sale. The Trustee may postpone sale of all or any portion of said property by
public announcement at such time and place of sale and from time to time
thereafter may postpone such sale by public announcement at the time fixed by
the preceding postponement. The Trustee shall deliver to the purchaser its deed
conveying the property so sold, but without any covenant or warranty, express or
implied. After deducting all allowable costs, fees, and expenses of the Trustee
in connection with the sale, the Trustee shall apply the proceeds of sale as set
forth in Section 5.9 hereof. Nothing contained herein shall be construed to
limit the right of the Agent to foreclose this Deed of Trust by judicial action.
The Agent shall further be entitled to bring an action upon any or all of the
Secured Obligations without attempting to foreclose this Deed of Trust either by
judicial action or by exercise of the power of sale.

5.2 Rights of the Trustee and the Agent with Respect to Personal Property
Constituting a Part of the Mortgaged Properties. During the continuation of an
Event of Default, the Agent will have all rights and remedies granted by law,
and particularly by the Uniform Commercial Code or similar statute in force in
any other state to the extent the same is applicable law, including, but not
limited to, the right to take possession of all personal property constituting a
part of the

                                     Page 15

<page>

Mortgaged Properties and for this purpose the Agent may enter upon any premises
on which any or all of such personal property is situated and take possession of
and operate such personal property (or any portion thereof) or remove it
therefrom. The Agent may require Trustor to assemble such personal property to
the extent feasible and make it available to the Agent at a place to be
designated by the Agent which is reasonably convenient to all parties. Unless
such personal property is perishable or threatens to decline speedily in value
or is of a type customarily sold on a recognized market, the Agent will give
Trustor reasonable notice of the time and place of any public sale or of the
time after which any private sale or other disposition of such personal property
is to be made. This requirement of sending reasonable notice will be met if the
notice is mailed by first-class mail, postage prepaid, to Trustor at the address
shown below the signatures at the end of this Deed of Trust (or at such other
address for notice hereafter designated by Trustor in conformity with the Credit
Agreement) at least ten (10) days before the time of the sale or disposition.

5.3 Rights of the Trustee with Respect to Fixtures Constituting a Part of the
Mortgaged Properties. During the continuation of an Event of Default, the
Trustee or the Agent, as applicable, may elect to treat the fixtures
constituting a part of the Mortgaged Properties as either real property
collateral or personal property collateral and then proceed to exercise such
rights as apply to such type of collateral.

5.4 Judicial Proceedings. The Trustee, with respect to the Deed of Trust
Mortgaged Properties, and the Agent, with respect to the Other Mortgaged
Properties, in lieu of or in addition to exercising any power of sale herein
given, may proceed by a suit or suits in equity or at law, whether for a
foreclosure hereunder, or for the sale of the Mortgaged Properties, or for the
specific performance of any covenant or agreement herein contained or in aid of
the execution of any power herein granted, or for the appointment of a receiver
pending any foreclosure hereunder or the sale of the Mortgaged Properties, or
for the enforcement of any other appropriate legal or equitable remedy.

5.5 Possession of the Mortgaged Properties. It shall not be necessary for the
Trustee or the Agent to have physically present or constructively in their
possession at any sale held by the Trustee, the Agent, or by any court, receiver
or public officer any of the Mortgaged Properties; and Trustor shall deliver to
the purchasers at such sale on the date of sale the Mortgaged Properties
purchased by such purchasers at such sale, and if it should be impossible or
impracticable for any of such purchasers to take actual delivery of the
Mortgaged Properties, then the title and right of possession to the Mortgaged
Properties shall pass to such purchaser at such sale as completely as if the
same had been actually present and delivered.

5.6 Certain Aspects of a Sale. The Agent and any Secured Party shall have the
right to become the purchaser at any sale made pursuant to this Article V, but
only the Agent shall have the right to credit upon the amount of the bid made
therefor the amount payable to the Secured Parties out of the net proceeds of
such sale. To the extent permitted by applicable law, recitals contained in any
conveyance made to any purchaser at any sale made hereunder shall

                                     Page 16

<page>

conclusively establish the truth and accuracy of the matters therein stated,
including, without limiting the generality of the foregoing, nonpayment of the
Secured Obligations, after the same have become due and payable, advertisement
and conduct of such sale in the manner provided herein or appointment of any
successor Trustee hereunder.

5.7 Receipt to Purchaser. Upon any sale, whether made under the power of sale
herein granted and conferred or by virtue of judicial proceedings, the receipt
of the Trustee, or of the officer making sale under judicial proceedings, shall
be sufficient discharge to the purchaser or purchasers at any sale for his or
their purchase money, and such purchaser or purchasers, or his or their assigns
or personal representatives, shall not, after paying such purchase money and
receiving such receipt of the Trustee or of such officer therefor, be obliged to
see to the application of such purchase money, or be in anywise answerable for
any loss, misapplication or nonapplication thereof.

5.8 Effect of Sale. Any sale or sales of the Mortgaged Properties, whether under
the power of sale herein granted and conferred or by virtue of judicial
proceedings, shall operate to divest all right, title, interest, claim and
demand whatsoever either at law or in equity, of Trustor of, in and to the
premises and the property sold, and shall be a perpetual bar, both at law and in
equity, against Trustor, and Trustor's successors or assigns, and against any
and all persons claiming or who shall thereafter claim all or any of the
property sold from, through or under Trustor or Trustor's successors or assigns.
Nevertheless, Trustor, if requested by the Agent or the Trustee to do so, shall
join in the execution and delivery of all proper conveyances, assignments and
transfers of the properties so sold.

5.9 Application of Proceeds. The proceeds of any sale of the Mortgaged
Properties, or any part thereof, whether under the power of sale herein granted
and conferred or by virtue of judicial proceedings, shall be applied in the
manner set forth in Section 4.01 of the Intercreditor Agreement.

5.10 Trustor's Waiver of Appraisement. Marshaling and Other Rights. Trustor
agrees, to the full extent that Trustor may lawfully so agree, that Trustor will
not at any time insist upon or plead or in any manner whatever claim the benefit
of any appraisement, valuation, stay, extension or redemption law now or
hereafter in force, in order to prevent or hinder the enforcement or foreclosure
of this Deed of Trust or the absolute sale of the Mortgaged Properties or the
possession thereof by any purchaser at any sale made pursuant to any provision
hereof, or pursuant to the decree of any court of competent jurisdiction;
Trustor, for Trustor and all who may claim through or under Trustor, so far as
Trustor or those claiming through or under Trustor now or hereafter lawfully
may, hereby waives the benefit of all such laws. Trustor, for Trustor and all
who may claim through or under Trustor, waives, to the extent that Trustor may
lawfully do so, any and all right to have the Mortgaged Properties marshaled
upon any foreclosure of the lien hereof, or sold in inverse order of alienation,
and agrees that the Trustee, the Agent or any court having jurisdiction to
foreclose such lien may sell the Mortgaged Properties as an entirety. Trustor,
for Trustor and all who may claim through or under Trustor, further waives, to
the full

                                     Page 17

<page>

extent that Trustor may lawfully do so, any requirement for posting a receiver's
bond or replevin bond or other similar type of bond if the Trustee or the Agent
commence an action for appointment of a receiver or an action for replevin to
recover possession of any of the Mortgaged Properties. If any law in this
paragraph referred to and now in force, of which Trustor or Trustor's successor
or successors might take advantage despite the provisions hereof, shall
hereafter be repealed or cease to be in force, such law shall not thereafter be
deemed to constitute any part of the contract herein contained or to preclude
the operation or application of the provisions of this paragraph.

5.11 Costs and Expenses. All costs and expenses (including attorneys' fees)
incurred by the Trustee, the Agent or the other Secured Parties in protecting
and enforcing their rights hereunder shall constitute a demand obligation owing
by Trustor to the party incurring such costs and expenses and shall draw
interest at the applicable rate specified in the Credit Agreement until paid,
all of which shall constitute a portion of the Secured Obligations.

5.12 Operation of the Mortgaged Properties by the Trustee or the Agent. Upon the
occurrence of an Event of Default and in addition to all other rights herein
conferred on the Trustee and the Agent, the Trustee, with respect to the Deed of
Trust Mortgaged Properties, or the Agent, with respect to the Other Mortgaged
Properties, (or any person, firm or corporation designated by the Trustee or the
Agent) shall have the right and power, but shall not be obligated, to enter upon
and take possession of any of the Mortgaged Properties, and to exclude Trustor,
and Trustor's agents or servants, wholly therefrom, and to hold, use,
administer, manage and operate the same to the extent that Trustor shall be at
the time entitled and in its place and stead. The Trustee or the Agent, or any
person, firm or corporation designated by the Trustee or by the Agent, may
operate the same without any liability to Trustor in connection with such
operations, except to use ordinary care in the operation of such properties, and
the Trustee or the Agent or any person, firm or corporation designated by the
Trustee or the Agent, shall have the right to collect, receive and receipt for
all Hydrocarbons produced and sold from said properties, to make repairs,
purchase machinery and equipment, conduct work-over operations, drill additional
wells and to exercise every power, right and privilege of Trustor with respect
to the Mortgaged Properties. When and if the expenses of such operation and
development (including costs of unsuccessful work-over operations or additional
wells) have been paid and the Secured Obligations paid, said properties shall,
if there has been no sale or foreclosure, be returned to Trustor.

                                   ARTICLE VI
                            Miscellaneous Provisions

6.1 Pooling and Unitization. Trustor shall have the right, and is hereby
authorized, to pool or unitize all or any part of any tract of land described in
Exhibit A, insofar as relates to the Mortgaged Properties, with adjacent lands,
leaseholds and other interests, when, in the reasonable judgment of Trustor, it
is necessary, advisable or desirable to do so in order to form a drilling unit
to facilitate the orderly development of that part of the Mortgaged Properties
affected thereby, or to comply with the requirements of any law or governmental
order or

                                     Page 18

<page>

regulation relating to the spacing of wells or proration of the production
therefrom; provided, however, that the Hydrocarbons produced from any unit so
formed shall be allocated among the separately owned tracts or interests
comprising the unit in a uniform manner consistently applied. Any unit so formed
may relate to one or more zones or horizons, and a unit formed for a particular
zone or horizon need not conform in area to any other unit relating to a
different zone or horizon, and a unit formed for the production of oil need not
conform in area with any unit formed for the production of gas. The interest of
Trustor in any such unit attributable to the Mortgaged Properties (or any part
thereof) included therein shall become a part of the Mortgaged Properties and
shall be subject to the lien hereof in the same manner and with the same effect
as though such unit and the interest of Trustor therein were specifically
described in Exhibit A.

6.2 Successor Trustee. Any Trustee may resign in writing addressed to the Agent
or may be removed at any time with or without cause by an instrument in writing
duly executed by the Agent. In case of the death, resignation or removal of a
Trustee, one or more successor Trustee may be appointed by the Agent by
instrument of substitution complying with any applicable requirements of law,
and in the absence of any such requirement without formality other than
appointment and designation in writing. Such appointment and designation shall
be full evidence of the right and authority to make the same and of all facts
therein recited, and upon the making of any such appointment and designation
this conveyance shall vest in the named successor Trustee, all the estate and
title of the prior Trustee in the Mortgaged Properties, and he or they shall
thereupon succeed to all the rights, powers, privileges, immunities and duties
hereby conferred upon the prior Trustee. All references herein to the Trustee
shall be deemed to refer to the Trustee from time to time acting hereunder.

6.3 Actions or Advances by the Agent, the Secured Parties or the Trustee. Each
and every covenant herein contained shall be performed and kept by Trustor
solely at Trustor's expense. If Trustor shall fail to perform or keep any of the
covenants of whatsoever kind or nature contained in this Deed of Trust, the
Agent, the Trustee, any Secured Party or any receiver appointed hereunder, may,
but shall not be obligated to, take action and/or make advances to perform the
same in Trustor's behalf, and Trustor hereby agrees to repay the reasonable
expense of such action and such advances upon demand plus interest at the
applicable rate specified in the Credit Agreement until paid. No such advance or
action by the Agent, the Trustee, any Secured Party or any receiver appointed
hereunder shall be deemed to relieve Trustor from any default hereunder.

6.4 The Mortgaged Properties to Revert; Release of this Deed of Trust. If the
Secured Obligations shall be paid in full in cash and all of the Commitments
have been terminated, then this Deed of Trust shall terminate and, to the extent
applicable under local law, all of the Mortgaged Properties shall revert to
Trustor and the entire estate, right, title and interest of the Trustee and the
Agent and the other Secured Parties granted hereunder shall thereupon cease; and
the Trustee and the Agent (for itself and as agent for the Secured Parties) in
such case shall, upon the request of Trustor and at Trustor's cost and expense,
deliver to Trustor proper instruments in recordable form acknowledging
satisfaction of this Deed of Trust.

6.5 Renewals, Amendments and Other Security. Renewals and extensions of the
Secured Obligations may be given at any time and amendments may be made to
agreements (other than this Deed of Trust) relating to any part of such Secured
Obligations or the Mortgaged Properties and the Trustee and the Secured Parties
may take or may now hold other security for the Secured Obligations, all without
notice to or consent of Trustor. The Trustee or the Secured Parties may resort
first to such other security or any part thereof or first to the security herein
given or any part thereof, or from time to time to either or both, even to the
partial or complete abandonment of either security, and such action shall not be
a waiver of any rights conferred by this Deed of Trust, which shall continue as
a first Lien upon and prior perfected security interest, subject to Liens
permitted by Section 6.02 of the Credit Agreement, in the Mortgaged Properties
not expressly released until the Secured Obligations are fully paid.

6.6 Deed of Trust as Assignment, etc. This Deed of Trust shall be deemed to be
and may be enforced from time to time as an assignment, chattel mortgage,
contract, deed of trust, financing statement, real estate mortgage, or security
agreement, and from time to time as any one or more thereof.

6.7 Unenforceable or Inapplicable Provisions. If any provision hereof is invalid
or unenforceable in any jurisdiction, the other provisions hereof shall remain
in full force and effect in such jurisdiction, and the invalidity of any
provision hereof in any jurisdiction shall not affect the validity or
enforceability of any such provision in any other jurisdiction. Any reference
herein contained to a statute or law of a state in which no part of the
Mortgaged Properties is situated shall be deemed inapplicable to, and not used
in, the interpretation hereof.

6.8 Rights Cumulative. Each and every right, power and remedy herein given to
the Trustee, the Agent or the other Secured Parties under this Deed of Trust

                                   ARTICLE II
                 Particular Covenants and Warranties of Trustor

2.1 Certain Representations and Warranties. Trustor represents and warrants to
the Trustee, the Agent and the other Secured Parties that, as of the date of
this Mortgage, (a) the Oil and Gas Properties described in Exhibit A hereto are
valid, subsisting leases, superior and paramount to all other Oil and Gas
Properties respecting the properties to which they pertain except where the
failure hereunder could not reasonably be expected to have a Material Adverse
Effect, (b) all producing wells located on the lands described in Exhibit A have
been drilled, operated and produced in conformity with all applicable laws,
statutes, rules or regulations, except where the failure hereunder could not
reasonably be expected to have a Material Adverse Effect, and are subject to no
penalties on account of past production which could reasonably be expected to
have a Material Adverse Effect, and such wells are in fact bottomed under and
are producing from, and the well bores are wholly within, the lands described in
Exhibit A except where the failure hereunder could not reasonably be expected to
have a Material Adverse Effect, (c) the Mortgaged Properties are free from all
encumbrances or liens whatsoever, except as may be specifically set forth in
Exhibit A or as permitted by Section 6.02 of the Credit Agreement, and (d) the
cover page to this Deed of Trust lists the correct legal name of Trustor and
Trustor is not now known by any trade name. Trustor will warrant and forever
defend the Mortgaged Properties unto the Trustee or the Agent, as applicable,
against every person whomsoever lawfully claiming the same or any part thereof
(subject, however, to The Liens permitted by Section 6.02 of the Credit
Agreement), and Trustor will maintain and preserve the Lien hereby created so
long as any of the Secured Obligations remains unpaid.

2.2 Operation of the Mortgaged Properties. So long as the Secured Obligations or
any part thereof remains unpaid, and whether or not Trustor is the operator of
the Mortgaged Properties, Trustor shall, at Trustor's own expense:

     A.   Cause to be paid, promptly as and when due and payable, all rentals
          and royalties (including shut-in royalties) payable in respect of the
          Mortgaged Properties, including payments into suspense accounts if
          appropriate, and all expenses incurred in or arising from the
          operation or development of the Mortgaged Properties except for those
          amounts being contested by Trustor in good faith in such manner as not
          to jeopardize the rights of the Trustee, the Agent and the other
          Secured Parties in and to the Mortgaged Properties; and

     B.   Notwithstanding anything in this Section to the contrary, as to any of
          the Mortgaged Properties which is a working interest operated by a
          person other than Trustor, Trustor agrees to take all such action and
          to exercise all rights as are commercially feasible and reasonably
          available to Trustor (including, but not limited to, all rights of
          Trustor under any operating agreement) to cause the operator of such
          property to comply with the covenants and agreements contained herein.

2.3 Recording, etc. Trustor will promptly, and at Trustor's expense, record,
register, deposit and file this Deed of Trust and every other instrument in
addition or supplemental hereto in such offices and places and at such times and
as often as may be reasonably necessary to preserve, protect and renew the Lien
hereof as a lien on and prior perfected security interest to all other security
interests other than the Lien granted pursuant to the First Lien Credit
Agreement, subject to Liens permitted by Section 6.02 of the Credit Agreement,
in real or personal property, as the case may be, and the rights and remedies of
the Trustee, the Agent and the other Secured Parties, and otherwise will do and
observe all things or matters reasonably necessary or expedient to be done or
observed by reason of any law or regulation of any state or of the United States
of America or of any other Governmental Authority, for the purpose of
effectively creating, maintaining and preserving the Lien on and in the
Mortgaged Properties.

                                   ARTICLE III
                       Assignment of Production and Leases

3.1 Assignment. As further security for the payment of the Secured Obligations,
Trustor hereby transfers, assigns, warrants and conveys to the Agent, for itself
and as agent for the Secured Parties, effective as of the Closing Date, at 7:00
A.M., local time, all Hydrocarbons which are thereafter produced from and which
accrue to the Mortgaged Properties (the "Production"), and all Proceeds
therefrom. During the continuance of an Event of Default, Trustor authorizes and
empowers the Agent to demand, collect, receive and receipt for all Production
and Proceeds. TRUSTOR IRREVOCABLY APPOINTS THE AGENT AS THE AGENT AND
ATTORNEY-IN-FACT OF TRUSTOR, FOR THE PURPOSE OF EXECUTING ANY TRANSFER ORDERS,
PAYMENT ORDERS, DIVISION ORDERS, RECEIPTS, RELEASES OR OTHER INSTRUMENTS
(COLLECTIVELY, "RECEIPTS") THAT THE AGENT DEEMS REASONABLY NECESSARY IN ORDER
FOR THE AGENT TO DEMAND, COLLECT, RECEIVE AND RECEIPT FOR PRODUCTION AND
PROCEEDS DURING THE CONTINUANCE OF AN EVENT OF DEFAULT. In addition, Trustor
agrees that, upon the Agent's request, Trustor shall promptly execute and
deliver to the Agent such Receipts as the Agent may deem reasonably necessary in
connection with the payment and delivery directly to the Agent of all Production
and Proceeds and to effectuate the purposes of this paragraph. All parties
producing, purchasing or receiving any Production or having Production or
Proceeds in their possession for which they or others are accountable to the
Agent by virtue of the provisions of this Article III are authorized and
directed to treat and regard the Agent as the assignee and transferee of Trustor
and entitled in Trustor's place and stead to receive Production and Proceeds;
and said parties and each of them shall be fully protected in so treating and
regarding the Agent and shall be under no obligation to see to the application
by the Agent of any Production or Proceeds received by it. Notwithstanding the
foregoing, the Agent, for itself and as agent for the Secured Parties, has
agreed not to exercise its right to directly receive delivery of Production and
payment of Proceeds immediately. Rather, each party producing, purchasing or
receiving Production may continue to make such deliveries or payments to Trustor
until such time as such party has received notice from the Agent that an

                                     Page 12

<page>

Event of Default has occurred and is continuing and that such party is directed
to make delivery or payment directly to the Agent.

3.2 Assignment of Leases. Trustor absolutely and unconditionally assigns,
transfers, sets over and conveys to Beneficiary the Mortgaged Properties,
including, without limitation, the Oil and Gas Properties and all existing and
future leases, subleases, tenancies, subtenancies, licenses, contracts, contract
rights, and occupancy and all other agreements, whether or not in writing,
affecting the use, enjoyment or occupancy of the Mortgaged Properties, together
with any extension, renewal, or replacement of the same. This assignment
includes all present and future leases and present and future agreements and is
effective without further or supplemental assignment, except as may be required
by any Governmental Authority.

3.3 License to Collect. Beneficiary hereby grants to Trustor an exclusive
license, revocable upon occurrence of an Event of Default, to possess, use, and
enjoy the Mortgaged Properties and to coiled and retain the proceeds of and from
the Mortgaged Properties, unless and until an Event of Default occurs.

3.4 Application of Proceeds. All payments received by the Agent pursuant to this
Article III shall be applied in the manner set forth in Section 4.01 of the
Intercreditor Agreement.

3.5 No Liability of the Agent in Collecting. The Agent is hereby absolved from
all liability for failure to enforce collection of any proceeds so assigned (and
no such failure shall be deemed to be a waiver of any right of the Agent under
this Article) and from all other responsibility in connection therewith, except
the responsibility to account to Trustor for funds actually received.

3.6 Assignment Not a Restriction on the Agent's Rights. Nothing herein contained
shall detract from or limit the absolute obligation of Trustor to make payment
of the Secured Obligations regardless of whether the proceeds assigned by this
Article would be sufficient to pay the same, and the rights under this Article
shall be in addition to all other security now or hereafter existing to secure
the payment of the Secured Obligations.

3.7 Status of Assignment. Notwithstanding the other provisions of this Article
and in addition to the other rights hereunder, the Trustee, the Agent or any
receiver appointed in judicial proceedings for the enforcement of this Deed of
Trust shall have the right to receive all of the Production and Proceeds after
the Secured Obligations have been declared due and payable and to apply all of
said proceeds as provided in Section 3.4 hereof. Upon any sale of the Mortgaged
Properties or any part thereof pursuant to Article V, the Hydrocarbons
thereafter produced from the property so sold, and the proceeds therefrom, shall
be included in such sale and shall pass to the purchaser free and clear of the
assignment contained in this Article.

3.8 Indemnity. Trustor shall indemnify the Trustee, the Agent and the other
Secured Parties, and all of the Related Parties of any of the foregoing Persons
(each such Person being called an "Indemnitee") against, and hold each
Indemnitee harmless from, any and all losses, claims,

                                     Page 13

<page>

damages, liabilities and related expenses, including the fees, charges and
disbursements of any counsel for any Indemnitee, incurred by or asserted against
any Indemnitee arising out of, in connection with, or as a result of, (i) the
assertion, either before or after the payment in full of the Secured
Obligations, that any Indemnitee received Production or Proceeds claimed by
third persons, or (ii) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on
contract, tort or any other theory and regardless of whether any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses are determined by a court of competent jurisdiction by final
and nonappealable judgment to have resulted from the gross negligence or wilful
misconduct of such Indemnitee (IT BEING UNDERSTOOD THAT IT IS THE INTENTION OF
THE PARTIES HERETO THAT, EXCEPT AS PROVIDED BY LAW TO THE CONTRARY, EACH OF THE
AGENTS BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS
NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY,
ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL). All amounts due under this
Section 3.8 shall be payable not later than thirty (30) days after written
demand therefor. The obligations of Trustor as herein set forth in this Section
3.8 shall survive the release, termination, foreclosure or assignment of this
Deed of Trust or any sale hereunder.

3.9 Rights Under Statutes. Trustor hereby appoints the Agent as its
attorney-in-fact to pursue any and all lien rights of Trustor to liens and
security interests in the Mortgaged Properties securing payment of Production
and Proceeds attributable to the Mortgaged Properties, including, but not
limited to, those liens and security interests provided for by AS 45.29.319.
Trustor further hereby assigns to the Agent any and all such liens, security
interests, financing statements, or similar interests of Trustor attributable to
its interests in the Mortgaged Properties and Production and Proceeds therefrom
arising under or created by said statutory provision, judicial decision, or
otherwise.

                                   ARTICLE IV
                                Events of Default

4.1 Events of Default Hereunder. The occurrence of an Event of Default under the
terms and provisions of the Credit Agreement and the continuance of such Event
of Default for the applicable period of grace, if any, shall be an "Event of
Default" hereunder.

                           Enforcement of the Security

5.1  Power of Sale and Foreclosure of Real Property Constituting a Part of the
     Mortgaged Properties.

     During the continuation of an Event of Default, the Trustee shall have the
right and power to sell, to the extent permitted by law, at one or more sales,
as an entirety or in parcels, as it may elect, the real property constituting a
part of the Deed of Trust Mortgaged Properties, at such place or places and
otherwise in such manner and upon such notice as may be required by law, or, in
the absence of any such requirement, as the Trustee may deem appropriate, and to
make conveyance to the purchaser or purchasers, without any covenant or
warranty, express or implied. The Trustee may postpone the sale of all or any
portion of such real property by public announcement at the time and place of
such sale, and from time to time thereafter may further postpone such sale by
public announcement made at the time of sale fixed by the preceding
postponement. The right of sale hereunder shall not be exhausted by one or any
sale, and the Trustee may make other and successive sales until all of the trust
estate be legally sold.

     Notice of any such sale shall be given as required by law, after the
completion of which the Trustee, without demand on Trustor, shall sell said
portion of the Deed of Trust Mortgaged Properties in Anchorage, Alaska (or at
such location as may be permitted by law if Anchorage is not permitted to be the
point of sale), at the place provided by law at the time fixed by the Trustee in
said notice of sale, either as a whole or in separate parcels and in such order
as it may determine, at public auction to the highest and best cash bidder. In
conformity with Section 5.6 hereof, the Agent shall have the right to make an
offset bid without cash in an amount not in excess of the balance owed by
Trustor at the time of the sale, including any sums expended by the Agent and
the Trustee under this Deed of Trust with interest, attorneys' fees, and costs
of sale. The Trustee may postpone sale of all or any portion of said property by
public announcement at such time and place of sale and from time to time
thereafter may postpone such sale by public announcement at the time fixed by
the preceding postponement. The Trustee shall deliver to the purchaser its deed
conveying the property so sold, but without any covenant or warranty, express or
implied. After deducting all allowable costs, fees, and expenses of the Trustee
in connection with the sale, the Trustee shall apply the proceeds of sale as set
forth in Section 5.9 hereof. Nothing contained herein shall be construed to
limit the right of the Agent to foreclose this Deed of Trust by judicial action.
The Agent shall further be entitled to bring an action upon any or all of the
Secured Obligations without attempting to foreclose this Deed of Trust either by
judicial action or by exercise of the power of sale.

5.2 Rights of the Trustee and the Agent with Respect to Personal Property
Constituting a Part of the Mortgaged Properties. During the continuation of an
Event of Default, the Agent will have all rights and remedies granted by law,
and particularly by the Uniform Commercial Code or similar statute in force in
any other state to the extent the same is applicable law, including, but not
limited to, the right to take possession of all personal property constituting a
part of the

                                     Page 15

<page>

Mortgaged Properties and for this purpose the Agent may enter upon any premises
on which any or all of such personal property is situated and take possession of
and operate such personal property (or any portion thereof) or remove it
therefrom. The Agent may require Trustor to assemble such personal property to
the extent feasible and make it available to the Agent at a place to be
designated by the Agent which is reasonably convenient to all parties. Unless
such personal property is perishable or threatens to decline speedily in value
or is of a type customarily sold on a recognized market, the Agent will give
Trustor reasonable notice of the time and place of any public sale or of the
time after which any private sale or other disposition of such personal property
is to be made. This requirement of sending reasonable notice will be met if the
notice is mailed by first-class mail, postage prepaid, to Trustor at the address
shown below the signatures at the end of this Deed of Trust (or at such other
address for notice hereafter designated by Trustor in conformity with the Credit
Agreement) at least ten (10) days before the time of the sale or disposition.

5.3 Rights of the Trustee with Respect to Fixtures Constituting a Part of the
Mortgaged Properties. During the continuation of an Event of Default, the
Trustee or the Agent, as applicable, may elect to treat the fixtures
constituting a part of the Mortgaged Properties as either real property
collateral or personal property collateral and then proceed to exercise such
rights as apply to such type of collateral.

5.4 Judicial Proceedings. The Trustee, with respect to the Deed of Trust
Mortgaged Properties, and the Agent, with respect to the Other Mortgaged
Properties, in lieu of or in addition to exercising any power of sale herein
given, may proceed by a suit or suits in equity or at law, whether for a
foreclosure hereunder, or for the sale of the Mortgaged Properties, or for the
specific performance of any covenant or agreement herein contained or in aid of
the execution of any power herein granted, or for the appointment of a receiver
pending any foreclosure hereunder or the sale of the Mortgaged Properties, or
for the enforcement of any other appropriate legal or equitable remedy.

5.5 Possession of the Mortgaged Properties. It shall not be necessary for the
Trustee or the Agent to have physically present or constructively in their
possession at any sale held by the Trustee, the Agent, or by any court, receiver
or public officer any of the Mortgaged Properties; and Trustor shall deliver to
the purchasers at such sale on the date of sale the Mortgaged Properties
purchased by such purchasers at such sale, and if it should be impossible or
impracticable for any of such purchasers to take actual delivery of the
Mortgaged Properties, then the title and right of possession to the Mortgaged
Properties shall pass to such purchaser at such sale as completely as if the
same had been actually present and delivered.

5.6 Certain Aspects of a Sale. The Agent and any Secured Party shall have the
right to become the purchaser at any sale made pursuant to this Article V, but
only the Agent shall have the right to credit upon the amount of the bid made
therefor the amount payable to the Secured Parties out of the net proceeds of
such sale. To the extent permitted by applicable law, recitals contained in any
conveyance made to any purchaser at any sale made hereunder shall

                                     Page 16

<page>

conclusively establish the truth and accuracy of the matters therein stated,
including, without limiting the generality of the foregoing, nonpayment of the
Secured Obligations, after the same have become due and payable, advertisement
and conduct of such sale in the manner provided herein or appointment of any
successor Trustee hereunder.

5.7 Receipt to Purchaser. Upon any sale, whether made under the power of sale
herein granted and conferred or by virtue of judicial proceedings, the receipt
of the Trustee, or of the officer making sale under judicial proceedings, shall
be sufficient discharge to the purchaser or purchasers at any sale for his or
their purchase money, and such purchaser or purchasers, or his or their assigns
or personal representatives, shall not, after paying such purchase money and
receiving such receipt of the Trustee or of such officer therefor, be obliged to
see to the application of such purchase money, or be in anywise answerable for
any loss, misapplication or nonapplication thereof.

5.8 Effect of Sale. Any sale or sales of the Mortgaged Properties, whether under
the power of sale herein granted and conferred or by virtue of judicial
proceedings, shall operate to divest all right, title, interest, claim and
demand whatsoever either at law or in equity, of Trustor of, in and to the
premises and the property sold, and shall be a perpetual bar, both at law and in
equity, against Trustor, and Trustor's successors or assigns, and against any
and all persons claiming or who shall thereafter claim all or any of the
property sold from, through or under Trustor or Trustor's successors or assigns.
Nevertheless, Trustor, if requested by the Agent or the Trustee to do so, shall
join in the execution and delivery of all proper conveyances, assignments and
transfers of the properties so sold.

5.9 Application of Proceeds. The proceeds of any sale of the Mortgaged
Properties, or any part thereof, whether under the power of sale herein granted
and conferred or by virtue of judicial proceedings, shall be applied in the
manner set forth in Section 4.01 of the Intercreditor Agreement.

5.10 Trustor's Waiver of Appraisement, Marshaling and Other Rights. Trustor
agrees, to the full extent that Trustor may lawfully so agree, that Trustor will
not at any time insist upon or plead or in any manner whatever claim the benefit
of any appraisement, valuation, stay, extension or redemption law now or
hereafter in force, in order to prevent or hinder the enforcement or foreclosure
of this Deed of Trust or the absolute sale of the Mortgaged Properties or the
possession thereof by any purchaser at any sale made pursuant to any provision
hereof, or pursuant to the decree of any court of competent jurisdiction;
Trustor, for Trustor and all who may claim through or under Trustor, so far as
Trustor or those claiming through or under Trustor now or hereafter lawfully
may, hereby waives the benefit of all such laws. Trustor, for Trustor and all
who may claim through or under Trustor, waives, to the extent that Trustor may
lawfully do so, any and all right to have the Mortgaged Properties marshaled
upon any foreclosure of the lien hereof, or sold in inverse order of alienation,
and agrees that the Trustee, the Agent or any court having jurisdiction to
foreclose such lien may sell the Mortgaged Properties as an entirety. Trustor,
for Trustor and all who may claim through or under Trustor, further waives, to
the full

                                     Page 17

<page>

extent that Trustor may lawfully do so, any requirement for posting a receiver's
bond or replevin bond or other similar type of bond if the Trustee or the Agent
commence an action for appointment of a receiver or an action for replevin to
recover possession of any of the Mortgaged Properties. If any law in this
paragraph referred to and now in force, of which Trustor or Trustor's successor
or successors might take advantage despite the provisions hereof, shall
hereafter be repealed or cease to be in force, such law shall not thereafter be
deemed to constitute any part of the contract herein contained or to preclude
the operation or application of the provisions of this paragraph.

5.11 Costs and Expenses. All costs and expenses (including attorneys' fees)
incurred by the Trustee, the Agent or the other Secured Parties in protecting
and enforcing their rights hereunder shall constitute a demand obligation owing
by Trustor to the party incurring such costs and expenses and shall draw
interest at the applicable rate specified in the Credit Agreement until paid,
all of which shall constitute a portion of the Secured Obligations.

5.12 Operation of the Mortgaged Properties by the Trustee or the Agent. Upon the
occurrence of an Event of Default and in addition to all other rights herein
conferred on the Trustee and the Agent, the Trustee, with respect to the Deed of
Trust Mortgaged Properties, or the Agent, with respect to the Other Mortgaged
Properties, (or any person, firm or corporation designated by the Trustee or the
Agent) shall have the right and power, but shall not be obligated, to enter upon
and take possession of any of the Mortgaged Properties, and to exclude Trustor,
and Trustor's agents or servants, wholly therefrom, and to hold, use,
administer, manage and operate the same to the extent that Trustor shall be at
the time entitled and in its place and stead. The Trustee or the Agent, or any
person, firm or corporation designated by the Trustee or by the Agent, may
operate the same without any liability to Trustor in connection with such
operations, except to use ordinary care in the operation of such properties, and
the Trustee or the Agent or any person, firm or corporation designated by the
Trustee or the Agent, shall have the right to collect, receive and receipt for
all Hydrocarbons produced and sold from said properties, to make repairs,
purchase machinery and equipment, conduct work-over operations, drill additional
wells and to exercise every power, right and privilege of Trustor with respect
to the Mortgaged Properties. When and if the expenses of such operation and
development (including costs of unsuccessful work- over operations or additional
wells) have been paid and the Secured Obligations paid, said properties shall,
if there has been no sale or foreclosure, be returned to Trustor.

                                   ARTICLE VI
                            Miscellaneous Provisions

6.1 Pooling and Unitization. Trustor shall have the right, and is hereby
authorized, to pool or unitize all or any part of any tract of land described in
Exhibit A, insofar as relates to the Mortgaged Properties, with adjacent lands,
leaseholds and other interests, when, in the reasonable judgment of Trustor, it
is necessary, advisable or desirable to do so in order to form a drilling unit
to facilitate the orderly development of that part of the Mortgaged Properties
affected thereby, or to comply with the requirements of any law or governmental
order or

                                     Page 18

<page>

regulation relating to the spacing of wells or proration of the production
therefrom; provided, however, that the Hydrocarbons produced from any unit so
formed shall be allocated among the separately owned tracts or interests
comprising the unit in a uniform manner consistently applied. Any unit so formed
may relate to one or more zones or horizons, and a unit formed for a particular
zone or horizon need not conform in area to any other unit relating to a
different zone or horizon, and a unit formed for the production of oil need not
conform in area with any unit formed for the production of gas. The interest of
Trustor in any such unit attributable to the Mortgaged Properties (or any part
thereof) included therein shall become a part of the Mortgaged Properties and
shall be subject to the lien hereof in the same manner and with the same effect
as though such unit and the interest of Trustor therein were specifically
described in Exhibit A.

6.2 Successor Trustee. Any Trustee may resign in writing addressed to the Agent
or may be removed at any time with or without cause by an instrument in writing
duly executed by the Agent. In case of the death, resignation or removal of a
Trustee, one or more successor Trustee may be appointed by the Agent by
instrument of substitution complying with any applicable requirements of law,
and in the absence of any such requirement without formality other than
appointment and designation in writing. Such appointment and designation shall
be full evidence of the right and authority to make the same and of all facts
therein recited, and upon the making of any such appointment and designation
this conveyance shall vest in the named successor Trustee, all the estate and
title of the prior Trustee in the Mortgaged Properties, and he or they shall
thereupon succeed to all the rights, powers, privileges, immunities and duties
hereby conferred upon the prior Trustee. All references herein to the Trustee
shall be deemed to refer to the Trustee from time to time acting hereunder.

6.3 Actions or Advances by the Agent, the Secured Parties or the Trustee. Each
and every covenant herein contained shall be performed and kept by Trustor
solely at Trustor's expense. If Trustor shall fail to perform or keep any of the
covenants of whatsoever kind or nature contained in this Deed of Trust, the
Agent, the Trustee, any Secured Party or any receiver appointed hereunder, may,
but shall not be obligated to, take action and/or make advances to perform the
same in Trustor's behalf, and Trustor hereby agrees to repay the reasonable
expense of such action and such advances upon demand plus interest at the
applicable rate specified in the Credit Agreement until paid. No such advance or
action by the Agent, the Trustee, any Secured Party or any receiver appointed
hereunder shall be deemed to relieve Trustor from any default hereunder.

6.4 The Mortgaged Properties to Revert; Release of this Deed of Trust. If the
Secured Obligations shall be paid in full in cash and all of the Commitments
have been terminated, then this Deed of Trust shall terminate and, to the extent
applicable under local law, all of the Mortgaged Properties shall revert to
Trustor and the entire estate, right, title and interest of the Trustee and the
Agent and the other Secured Parties granted hereunder shall thereupon cease; and
the Trustee and the Agent (for itself and as agent for the Secured Parties) in
such case shall, upon the request of Trustor and at Trustor's cost and expense,
deliver to Trustor proper instruments in recordable form acknowledging
satisfaction of this Deed of Trust.

6.5 Renewals, Amendments and Other Security. Renewals and extensions of the
Secured Obligations may be given at any time and amendments may be made to
agreements (other than this Deed of Trust) relating to any part of such Secured
Obligations or the Mortgaged Properties and the Trustee and the Secured Parties
may take or may now hold other security for the Secured Obligations, all without
notice to or consent of Trustor. The Trustee or the Secured Parties may resort
first to such other security or any part thereof or first to the security herein
given or any part thereof, or from time to time to either or both, even to the
partial or complete abandonment of either security, and such action shall not be
a waiver of any rights conferred by this Deed of Trust, which shall continue as
a Lien upon and prior perfected security interest, subject to Liens permitted by
Section 6.02 of the Credit Agreement, in the Mortgaged Properties not expressly
released until the Secured Obligations are fully paid.

6.6 Deed of Trust as Assignment, etc. This Deed of Trust shall be deemed to be
and may be enforced from time to time as an assignment, chattel mortgage,
contract, deed of trust, financing statement, real estate mortgage, or security
agreement, and from time to time as any one or more thereof.

6.7 Unenforceable or Inapplicable Provisions. If any provision hereof is invalid
or unenforceable in any jurisdiction, the other provisions hereof shall remain
in full force and effect in such jurisdiction, and the invalidity of any
provision hereof in any jurisdiction shall not affect the validity or
enforceability of any such provision in any other jurisdiction. Any reference
herein contained to a statute or law of a state in which no part of the
Mortgaged Properties is situated shall be deemed inapplicable to, and not used
in, the interpretation hereof.

6.8 Rights Cumulative. Each and every right, power and remedy herein given to
the Trustee, the Agent or the other Secured Parties under this Deed of Trust
shall be cumulative and not exclusive; and each and every right, power and
remedy whether specifically herein given or otherwise existing may be exercised
from time to time and so often and in such order as may be deemed expedient by
the Trustee, the Agent or the other Secured Parties, as the case may be, and the
exercise, or the beginning of the exercise, of any such right, power or remedy
shall not be deemed a waiver of the right to exercise, at the same time or
thereafter, any other right, power or remedy. No delay or omission by the
Trustee, the Agent or the other Secured Parties in the exercise of any right,
power or remedy shall impair any such right, power or remedy or operate as a
waiver thereof or of any other right, power or remedy then or thereafter
existing.

6.9 Waiver by the Trustee. Any and all covenants in this Deed of Trust may from
time to time be waived by instrument in writing signed by the Trustee and the
Agent to such extent and in such manner as the Required Lenders may desire, but
no such waiver shall ever affect or impair either the Trustee's, the Agent's or
the other Secured Parties' rights or liens or security interests hereunder,
except to the extent specifically stated in such written instrument.

from time to time serving hereunder shall have the absolute right, acting
individually, to take any action and to exercise any right, remedy, power,
privilege or authority conferred upon Trustee.

6.11 No Partnership. Nothing contained in this Deed of Trust is intended to, or
shall be construed as, creating to any extent and in any manner whatsoever, any
partnership, joint venture, or association among Trustor, the Trustee, the
Agent, the other Secured Parties and their respective Affiliates, or in any way
as to make the Agent, the other Secured Parties or the Trustee co-principals

district in which such counterpart is to be recorded or filed may have been
omitted. Complete copies of this Deed of Trust containing the entire Exhibit A
have been retained by Trustor and the Agent.

6.15 Special Filing as Financing Statement. This Deed of Trust shall likewise be
a Security Agreement and a Financing Statement. This Deed of Trust shall be
filed for record, among other places, in the real estate records of each
recording district in which any portion of the real property covered by the Oil
and Gas Properties described in Exhibit A hereto is situated, and, when filed

Properties and (2) oil, gas and other minerals extracted from the Oil and Gas
Properties (and accounts arising from the sale of said oil, gas and other
minerals) at the wellheads of wells located now or hereafter on the lands
described in Exhibit A hereto. At the option of the Agent, a carbon,
photographic or other reproduction of this Deed of Trust or of any financing
statement covering the Mortgaged Properties or any portion thereof shall be
sufficient as a financing statement and may be filed as such.

6.16 Notices. Except as otherwise expressly provided herein, any notice,
request, demand or other instrument which may be required or permitted to be

Section 9.01 of the Credit Agreement.

OR WILLFUL MISCONDUCT. The Trustee shall have the right to rely on any
instrument, document or signature authorizing or supporting any action taken or
proposed to be taken by them hereunder, believed by them in good faith to be
