Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act), any event occurs as a result of which the Final Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend or supplement the Final Prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Company will promptly notify the Representatives and will, upon its request, prepare and file with the SEC an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.

The Company agrees to indemnify and hold harmless each Underwriter and each person who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Notes as originally filed or in any amendment thereof, or in the Basic Prospectus, any Preliminary Final Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus, the Preliminary Canadian Offering Memorandum, the Canadian Offering Memorandum or in any amendment thereof or supplement thereto, 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, and agrees to reimburse each such indemnified party to the extent set forth below, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives or directly by any Underwriter specifically for use therein (it being understood and agreed that the only such information furnished by any Underwriter consists of such information described as such in any Underwriter Blood Letter provided by such parties). This indemnity agreement will be in addition to any liability which the Company may otherwise have.

Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives or directly by any Underwriter for use in the preparation of the documents referred to in the foregoing indemnity (it being understood and agreed that the only such information furnished by any Underwriter consists of such information described as such in any Underwriter Blood Letter provided by such parties). This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action (including any governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under clause (a) or (b) of this Section 9, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under clause (a) or (b) of this Section 9. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will 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 reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party). In any such proceeding, any indemnified party shall have the right to obtain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnified party and the indemnifying party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate identified firm (in addition to any identified local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives in the case of parties to be indemnified pursuant to paragraph (a) of this Section 9 and by the Company in the case of parties to be indemnified pursuant to paragraph (b) of this Section 9. An indemnifying party shall not be liable for any settlement of any proceeding effected without its prior written consent, but if

settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld or delayed), effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding 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 the indemnified party.

To the extent the indemnification provided for in Section 9(a) or 9(b) hereof is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and each Underwriter, on the other hand, from the offering of such 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, on the one hand, and each Underwriter, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and each Underwriter, on the other hand, in connection with the offering of such Notes shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Notes (before deducting expenses) received by the Company bear to the total discounts and commissions received by each Underwriter in respect thereof. The relative fault of the Company, on the one hand, and each Underwriter, on the other hand, 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 or by such Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Each Underwriter’s obligation to contribute pursuant to this Section 9 shall be several in the proportion that the principal amount of Notes the sale of which by such Underwriter gave rise to such losses, claims, damages or liabilities bears to the aggregate principal amount of Notes the sale of which by all Underwriters gave rise to such losses, claims, damages or liabilities, and not joint.

The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to Section 9(d) hereof were determined by pro rata

allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(d) hereof. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(d) hereof shall be deemed to include, subject to the limitations set forth above, 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 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes referred to in Section 9(d) hereof that were offered and sold to the public through such Underwriter exceeds the amount of any damages that such 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 Section 11 (f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.
