interference with its business from fire, explosion, flood or other calamity,
whether or not covered by insurance, or from any labor dispute or court or
governmental action, order or decree, other than as set forth or contemplated in

          (y) The historical financial statements (including the related notes
and supporting schedules) included in the Preliminary Offering Memorandum and
the Final Offering Memorandum present fairly in all material respects the
financial condition and results of operations of the entities purported to be
shown thereby on the basis stated therein, at the dates and for the periods
indicated, and have been prepared in conformity with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved, except in each case as set forth or contemplated in the Preliminary
Offering Memorandum.
          (z) The pro forma financial statements included in the Preliminary
Offering Memorandum and the Final Offering Memorandum include assumptions that
provide a reasonable basis for presenting the significant effects directly
attributable to the transactions and events described therein, the related pro
forma adjustments give appropriate effect to those assumptions, and the pro
forma adjustments reflect the proper application of those adjustments to the
historical financial statement amounts in the pro forma financial statements

          (cc) The oil and gas reserve estimates of the Company and its
Subsidiaries (exclusive of the Forest Gulf of Mexico operations) contained in
the Preliminary Offering Memorandum and the Final Offering Memorandum are based
on estimates made in reserve reports prepared by an independent petroleum

Final Offering Memorandum, such reserve estimates fairly reflect the oil and gas
reserves of the Company and its Subsidiaries (exclusive of the Forest Gulf of
Mexico operations) at the dates indicated in the Preliminary Offering Memorandum
and are in accordance with the Commission guidelines applied on a consistent
basis throughout the periods involved. The oil and gas reserve estimates of the
Forest Gulf of Mexico operations contained in the Preliminary Offering
Memorandum are based on estimates made by internal staff engineers of Forest Oil
Corporation, which estimates were audited by an independent petroleum
engineering firm as set forth in the Preliminary Offering Memorandum, such
reserve estimates fairly reflect the oil and gas reserves of the Forest Gulf of
Mexico operations at the dates indicated in the Preliminary Offering Memorandum
and are in accordance with the Commission guidelines applied on a consistent
basis throughout the periods involved. The information underlying the estimates
described above that was supplied to Ryder Scott for the purposes of preparing
the reserve report and audit referred to above, including production and costs
of operation, was true and correct in all material respects on the dates such
estimates were made, and such information was supplied and was prepared in
accordance with customary industry practices; other than normal production of
the reserves, product price fluctuations, fluctuations of demand for such
products, hurricanes, loop currents and other adverse weather conditions,
unavailability or increased costs of rigs, equipment, supplies or personnel, the
timing of third party operations and other factors disclosed in the Preliminary
Offering Memorandum and the Final Offering Memorandum, the Company is not aware
of any facts or circumstances that would result in a materially adverse change
in the aggregate net reserves, or the present value of the future net cash flows
therefrom as described in the Preliminary Offering Memorandum and the Final
Offering Memorandum and as reflected in the Reserve Reports; the estimates of
such reserves and present value as described in the Preliminary Offering
Memorandum and the Final Offering Memorandum and reflected in the Reserve Report
referenced therein have been prepared in a manner that complies with the
applicable requirements of the rules under the Act with respect to proved
reserves.
          (dd) The Company or the subsidiaries have legal, valid and defensible
title to substantially all the interests in oil and gas properties underlying
the Company’s estimates of its net proved reserves contained in the Preliminary
Offering Memorandum and the Final Offering Memorandum and to substantially all
other real and personal property reflected in the Preliminary Offering
Memorandum and the Final Offering Memorandum as assets owned by them, in each
case free and clear of all liens, encumbrances and defects, except such as are
described in the Preliminary Offering Memorandum or as would not be reasonably
expected to have a Material Adverse Effect; and any other real property and
buildings held under lease by the Company or the subsidiaries are held by them
under valid, subsisting and enforceable leases, with such exceptions as are not
material and do not materially interfere with the use made and proposed to be
made of such property and buildings by the Company or its subsidiaries; and the
care taken by the Company and its subsidiaries with respect to acquiring or
otherwise procuring such leases, options to lease, drilling rights and
concessions or other property interests was generally consistent with standard
industry practices in the areas in which the Company operates

produce hydrocarbons.
          (ee) The Company and each of the Guarantors carry, or are covered by,
insurance in such amounts and covering such risks as is adequate for the conduct
of their respective businesses and the value of their respective properties and
as is customary for companies engaged in similar businesses in similar
industries.
          (ff) There are no legal or governmental proceedings pending to which
the Company or any of its subsidiaries is a party or of which any property or
assets of the Company or any of its subsidiaries is the subject that, if
determined adversely to the Company or any of its subsidiaries, is reasonably
likely to have a Material Adverse Effect, and to the knowledge of the Company

or governmental authority having jurisdiction; (ii) a material disruption in
securities settlement, payment or clearance services in the United States;
(iii) a banking moratorium has been declared by Federal or state authorities;
(iv) any attack on, outbreak or escalation of hostilities or act of terrorism
involving the United States, any declaration of war by Congress or any other

(v) the occurrence of any other calamity, crisis (including without limitation
as a result of terrorist activities), or material adverse change in general

surveillance or review, or has changed its outlook with respect to, its rating
of the Notes (other than an announcement with positive implications of a
possible upgrading).
          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Initial Purchasers.
     8. Indemnification and Contribution.
          (a) The Company and each Guarantor, hereby agree, jointly and
severally, to indemnify and hold harmless each Initial Purchaser, its directors,
officers and employees and each person, if any, who controls any Initial
Purchaser within the meaning of the Act, from and against any loss, claim,
damage or liability, joint or several, or any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or action
relating to purchases and sales of Notes), to which that Initial Purchaser,
director, officer, employee or controlling person may become subject, under the
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in the Pricing Disclosure Package,
the Final Offering Memorandum or in any amendment or supplement thereto, (B) in
any Blue Sky application or other document prepared or executed by the Company
or any Guarantor (or based upon any written information furnished by the Company
or any Guarantor) specifically for the purpose of qualifying any or all of the
Notes under the securities laws of any state or other jurisdiction (any such
application, document or information being hereinafter called a “Blue Sky
Application”) or (C) in any materials or information provided to investors by,
or with the approval of, the Company in connection with the marketing of the
offering of the Notes (“Marketing Materials”), including any roadshow or
investor presentations made to investors by the Company (whether in person or
electronically), (ii) the omission or alleged omission to state in the Pricing
Disclosure Package, the Final Offering Memorandum, or in any amendment or
supplement thereto, or in any Blue Sky Application or in any Marketing
Materials, any material fact required to be stated therein or necessary in order
to make the statements therein, in light of

22

--------------------------------------------------------------------------------

 

the circumstances under which they were made, not misleading or (iii) any act or
failure to act or any alleged act or failure to act by any Initial Purchaser in
connection with, or relating in any manner to, the Notes or the offering
contemplated hereby, and that is included as part of or referred to in any loss,
claim, damage, liability or action arising out of or based upon matters covered
by clause (i) or (ii) above (provided that the Company and the Guarantors shall
not be liable under this clause (iii) to the extent that it is determined in a
final judgment by a court of competent jurisdiction that such loss, claim,
damage, liability or action resulted directly from any such acts or failures to
act undertaken or omitted to be taken by such Initial Purchaser through its
gross negligence or willful misconduct), and shall reimburse each Initial
Purchaser and each such director, officer, employee or controlling person
promptly upon demand for any legal or other expenses reasonably incurred by that
Initial Purchaser, director, officer, employee or controlling person in
connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action as such expenses are incurred;
provided, however, that the Company and the Guarantors shall not be liable in
any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, any untrue statement or alleged untrue
statement or omission or alleged omission made in the Pricing Disclosure
Package, the Final Offering Memorandum, or in any such amendment or supplement
thereto, or in any Blue Sky Application or in any Marketing Materials, in
reliance upon and in conformity with written information concerning such Initial
Purchaser furnished to the Company through the Initial Purchasers by or on
behalf of any Initial Purchaser specifically for inclusion therein. The
foregoing indemnity agreement is in addition to any liability that the Company
or the Guarantors may otherwise have to any Initial Purchaser or to any
director, officer, employee or controlling person of that Initial Purchaser.
          (b) Each Initial Purchaser, severally and not jointly, hereby agrees
to indemnify and hold harmless the Company, each Guarantor, their respective
officers and employees, each of their respective directors, and each person, if
any, who controls the Company or any Guarantor within the meaning of the Act,
from and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof, to which the Company, any Guarantor or any such
director, officer, employee or controlling person may become subject, under the
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in the Pricing Disclosure Package,
the Final Offering Memorandum or in any amendment or supplement thereto, (B) in
any Blue Sky Application, or (C) in any Marketing Materials or (ii) the omission
or alleged omission to state in the Pricing Disclosure Package, the Final
Offering Memorandum, or in any amendment or supplement thereto, or in any Blue
Sky Application or in any Marketing Materials any material fact required to be
stated therein or necessary to make the statements therein not misleading, but
in each case only to the extent that the untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information concerning such Initial Purchaser furnished
to the Company by or on behalf of that Initial Purchaser specifically for
inclusion therein, and shall reimburse the Company, any Guarantor and any such
director, officer, employee or controlling person for any legal or other
expenses reasonably incurred by the Company, any Guarantor or any such director,
officer, employee or controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred. The foregoing indemnity agreement is in
addition to any liability that any Initial

23

--------------------------------------------------------------------------------

 

Purchaser may otherwise have to the Company, any Guarantor or any such director,
officer, employee or controlling person.
          (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability that it may have under this Section 8 except to the extent it has been
materially prejudiced by such failure and; provided, further, that the failure
to notify the indemnifying party shall not relieve it from any liability that it
may have to an indemnified party otherwise than under this Section 8. If any
such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the Initial Purchasers shall have the right to employ counsel to represent
jointly the Initial Purchasers and their respective directors, officers,
employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought by the Initial Purchasers
against the Company or any Guarantor under this Section 8 if, in the reasonable
judgment of the Initial Purchasers, it is advisable for the Initial Purchasers
and those directors, officers, employees and controlling persons to be jointly
represented by separate counsel, and in that event the fees and expenses of such
separate counsel shall be paid by the Company or any Guarantor. No indemnifying
party shall (i) without the prior written consent of the indemnified parties
(which consent shall not be unreasonably withheld), settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified parties are
actual or potential parties to such claim or action) unless such settlement,
compromise or consent includes an unconditional release of each indemnified
party from all liability arising out of such claim, action, suit or proceeding,
and does not include any statement as to or any admission of fault, culpability
or failure to act by or on behalf of any indemnified party, or (ii) be liable
for any settlement of any such action effected without its written consent
(which consent shall not be unreasonably withheld), but if settled with the
consent of the indemnifying party or if there be a final judgment for the
plaintiff in any such action, the indemnifying party agrees to indemnify and
hold harmless any indemnified party from and against any loss or liability by
reason of such settlement or judgment.
          (d) If the indemnification provided for in this Section 8 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be

24

--------------------------------------------------------------------------------

 

appropriate to reflect the relative benefits received by the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other, from the
offering of the Notes or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company and the Guarantors, on the one hand, and the
Initial Purchasers, on the other, with respect to the statements or omissions
that resulted in such loss, claim, damage or liability, or action in respect
thereof, as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Guarantors, on the one hand, and the
Initial Purchasers on the other with respect to such offering shall be deemed to
be in the same proportion as the total net proceeds from the offering of the
Notes purchased under this Agreement (before deducting expenses) received by the
Company and the Guarantors on the one hand, and the total discounts and
commissions received by the Initial Purchasers with respect to the Notes
purchased under this Agreement, on the other hand, bear to the total gross
proceeds from the offering of the Notes under this Agreement. The relative fault
shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Company, the Guarantors or the
Initial Purchasers, the intent of the parties and their relative knowledge,
access to information and opportunity to correct or prevent such statement or
omission. For purposes of the preceding two sentences, the net proceeds deemed
to be received by the Company shall be deemed to be also for the benefit of the
Guarantors and information supplied by the Company shall also be deemed to have
been supplied by the Guarantors. The Company, the Guarantors, and the Initial
Purchasers agree that it would not be just and equitable if contributions
pursuant to this Section 8(d) were to be determined by pro rata allocation (even
if the Initial Purchasers were treated as one entity for such purpose) or by any
other method of allocation that does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this Section 8(d) shall be deemed to include, for
purposes of this Section 8(d), any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 8(d), no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total discounts and commissions received by such Initial Purchaser
with respect to the offering of the Notes exceeds the amount of any damages that
such Initial Purchaser has otherwise paid or become liable to pay by reason of
any untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations
to contribute as provided in this Section 8(d) are several in proportion to
their respective underwriting obligations and not joint.
          (e) The Initial Purchasers severally confirm and the Company and the
Guarantors acknowledge that the statements with respect to the offering of the
Notes by the Initial Purchasers set forth on the second to last paragraph on the
front cover of the Final Offering Memorandum and in the section entitled “Plan
of Distribution” in the Offering Memorandum are correct and constitute the only
information concerning such Initial Purchasers furnished in writing to the
Company or any Guarantor by or on behalf of the Initial Purchasers specifically
for inclusion in Preliminary Offering Memorandum or the Final Offering
Memorandum.

25

--------------------------------------------------------------------------------

 

     9. Defaulting Initial Purchasers. If, on the Closing Date, any Initial
Purchaser defaults in the performance of its obligations under this Agreement,
the remaining non-defaulting Initial Purchasers shall be obligated to purchase
the Notes that the defaulting Initial Purchaser agreed but failed to purchase on
the Closing Date in the respective proportions that the number of Notes set
opposite the name of each remaining non-defaulting Initial Purchaser in
Schedule I hereto bears to the total number of Notes set opposite the names of
all the remaining non-defaulting Initial Purchasers in Schedule I hereto;
provided, however, that the remaining non-defaulting Initial Purchasers shall
not be obligated to purchase any of the Notes on the Closing Date if the total
number of Notes that the defaulting Initial Purchaser or Initial Purchasers
agreed but failed to purchase on such date exceeds 9.09% of the total number of
Notes to be purchased on the Closing Date, and any remaining non-defaulting
Initial Purchasers shall not be obligated to purchase more than 110% of the
number of Notes that it agreed to purchase on the Closing Date pursuant to the
terms of Section 3. If the foregoing maximums are exceeded, the remaining
non-defaulting Initial Purchasers, or those other Initial Purchasers reasonably
satisfactory to the Initial Purchasers who so agree, shall have the right, but
shall not be obligated, to purchase, in such proportion as may be agreed upon
among them, all the Notes to be purchased on the Closing Date. If the remaining
Initial Purchasers or other Initial Purchasers reasonably satisfactory to the
Initial Purchasers do not elect to purchase the Notes that the defaulting
Initial Purchaser or Initial Purchasers agreed but failed to purchase on the
Closing Date, this Agreement shall terminate without liability on the part of
any non-defaulting Initial Purchaser or the Company or the Guarantors, except
that the Company and the Guarantors will continue to be liable for the payment
of expenses to the extent set forth in Sections 6 and 11.
          Nothing contained herein shall relieve a defaulting Initial Purchaser
of any liability it may have to the Company or any Guarantor for damages caused
by its default. If other Initial Purchasers are obligated or agree to purchase
the Notes of a defaulting or withdrawing Initial Purchaser, either the remaining
Initial Purchasers or the Company may postpone the Closing Date for up to seven
full business days in order to effect any changes that in the opinion of counsel
for the Company or counsel for the Initial Purchasers may be necessary in the
Pricing Disclosure Package, the Final Offering Memorandum or in any other
document or arrangement.
     10. Termination. The obligations of the Initial Purchasers hereunder may be
terminated by the Initial Purchasers by notice given to and received by the
Company prior to delivery of and payment for the Notes if, prior to that time,
any of the events described in Sections 7(j) or 7(o) shall have occurred or if
the Initial Purchasers shall decline to purchase the Notes for any reason
permitted under this Agreement.
     11. Reimbursement of Initial Purchasers’ Expenses. If the Company fails to
tender the Notes for delivery to the Initial Purchasers by reason of any
failure, refusal or inability on the part of the Company or any Guarantor to
perform any agreement on their part to be performed, or because any other
condition of the obligations hereunder required to be fulfilled by the Company
or any Guarantor is not fulfilled, the Company and the Guarantors shall
reimburse the Initial Purchasers for all reasonable out-of-pocket expenses
(including reasonable fees and disbursements of counsel) incurred by the Initial
Purchasers in connection with this Agreement and the proposed purchase of the
Notes, and upon demand the Company and the Guarantors shall pay the full amount
thereof to Lehman Brothers Inc. for the benefit of the Initial Purchasers.

26

--------------------------------------------------------------------------------

 

     12. Research Independence. The Company and the Guarantors acknowledge that
the Initial Purchasers’ research analysts and research departments are required
to be independent from their respective investment banking divisions and are
subject to certain regulations and internal policies, and that such Initial
Purchasers’ research analysts may hold and make statements or investment
recommendations and/or publish research reports with respect to the Company
and/or the offering that differ from the views of its investment bankers. The
Company and the Guarantors hereby waive and release, to the fullest extent
permitted by law, any claims that the Company and/or any Guarantor may have
against any Initial Purchaser with respect to any conflict of interest that may
arise from the fact that the views expressed by their independent research
analysts and research departments may be different from or inconsistent with the
views or advice communicated to the Company or any of the Guarantors by the
investment banking division of any such Initial Purchaser. The Company and the
Guarantors acknowledge that each of the Initial Purchasers is a full service
securities firm and as such from time to time, subject to applicable securities
laws, may effect transactions for its own account or the account of its
customers and hold long or short positions in debt or equity securities of the
companies which may be the subject of the transactions contemplated by this
Agreement.
     13. No fiduciary duty. The Company and the Guarantors acknowledge and agree
that in connection with this offering, sale of the Notes or any other services
the Initial Purchaser may be deemed to be providing hereunder, notwithstanding
any preexisting relationship, advisory or otherwise, between the parties or any
oral representations or assurances previously or subsequently made by the
Initial Purchasers: (i) no fiduciary or agency relationship between the Company
and/or any of the Guarantors and any other person, on the one hand, and the
Initial Purchasers, on the other, exists; (ii) the Initial Purchasers are not
acting as advisors, expert or otherwise, to the Company or any of the Guarantors
in connection with the offering contemplated hereby, including, without
limitation, with respect to the determination of the offering price of the
Notes, and such relationship between the Company and/or any of the Guarantors,
on the one hand, and the Initial Purchasers, on the other, is entirely and
solely commercial, based on arms-length negotiations; (iii) any duties and
obligations that the Initial Purchasers may have to the Company and/or any of
the Guarantors shall be limited to those duties and obligations specifically
stated herein; and (iv) the Initial Purchasers and their respective affiliates
may have interests that differ from those of the Company and the Guarantors. The
Company and the Guarantors hereby waive any claims that the Company and/or any
of the Guarantors may have against the Initial Purchasers with respect to any
breach of fiduciary duty in connection with the offering of the Notes.
     14. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:
