(xvii) If the Indenture, the Securities and this Agreement were sought to be enforced in the Province of Alberta in accordance with the laws applicable thereto, as chosen by the parties, namely, New York law, a court of competent jurisdiction in the Province of Alberta would and to the extent specifically pleaded and proved as a fact by expert evidence, recognize the choice of New York law and apply such law to all issues that, under the conflict of laws rules of the Province of Alberta, are to be determined in accordance with the proper or general law of a contract, provided that none of the provisions of the Indenture, the Securities or this Agreement, or of New York law, are contrary to public policy as that term is understood under the laws of the Province of Alberta and the federal laws of Canada applicable therein; and further provided that, in matters of procedure (as that term is understood under the laws of the Province of Alberta and the federal laws of Canada applicable therein), the laws of the Province of Alberta will be applied, and a court of competent jurisdiction in the Province of Alberta will retain discretion to decline to hear such GULF CANADA RESOURCES LIMITED 8.375% SENIOR NOTES DUE 2005 PAGE 14 15 action and apply such law (A) if it is contrary to public policy (as that term is understood under the laws of the Province of Alberta and the federal laws of Canada applicable therein) for such court to do so, or (B) if it is not the proper forum to hear such an action or (C) if concurrent proceedings are being brought elsewhere;

given the limitations inherent in the independent verification of factual matters and the character of determinations involved in the filing and obtaining of a receipt from the ASC for the Prospectus and the registration process, such counsel need not pass upon and need not assume any responsibility for the accuracy, completeness or genuineness of the statements included in the Prospectus or the Prospectus Supplement (including the documents incorporated therein by reference), except for those made under the captions "Description of the Notes," "Description of Debt Securities" and "Certain Income Tax Considerations -- Certain Canadian Federal Income Tax Considerations," insofar as such statements constitute summaries of the matters, documents or proceedings therein described;

(x) Assuming this Agreement has been duly authorized, executed and delivered under Canadian federal and Alberta law, this Agreement has been duly executed and delivered by the Company; (xi) The Indenture has been duly qualified under the U.S. Trust Indenture Act of 1939, as amended; (xii) Each part of the Registration Statement, when such part became effective, and the Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement, appeared on their face to be appropriately responsive in all material respects relevant to the offering of the Securities, to the requirements of the Act, the Trust Indenture Act and the applicable rules and regulations of the Commission thereunder; (xiii) As United States counsel to the Company, they reviewed the Registration Statement and the Prospectus, participated in discussions with representatives of the Under writer and those of the Company, their accountants and the Company's Canadian counsel, and advised the Company as to the requirements of the Act and the applicable rules and regulations thereunder;

The rights of indemnity contained in this Section 8(a) in respect of a claim based on a misrepresentation or omission or alleged misrepresentation or omission in any Preliminary Shelf Prospectus shall not apply if the Prospectus or any Supplementary Material corrects in all material respects such misrepresentation or omission or alleged misrepresentation or omission, the Underwriter was required by the Act to deliver the Prospectus or such Supplementary Material to the person asserting such claim, and the Underwriter failed to do so. (b) The Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Shelf Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, or the Shelf Information, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Shelf Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement, or the Shelf Information, in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than GULF CANADA RESOURCES LIMITED 8.375% SENIOR NOTES DUE 2005 PAGE 22 23 reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriter on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include 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 subsection (d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of GULF CANADA RESOURCES LIMITED 8.375% SENIOR NOTES DUE 2005 PAGE 23 24 Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Underwriter within the meaning of the Act; and the obligations of the Underwriter under this Section 8 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company within the meaning of the Act. 9.
