of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made when such Prospectus is delivered, not misleading, or, if for any other reason it shall be necessary to amend or supplement the Prospectus or to file under the Exchange Act any document incorporated by reference in the Prospectus in order to comply with the Securities Act, to notify the Representatives and, upon their request, to file such document and to prepare and furnish without charge to each Underwriter and to any dealer in securities as many copies as the Representatives may from time to time reasonably request of an amended or supplemented Prospectus which will correct such statement or omission or effect such compliance.

(h) Promptly from time to time to take such action as the Representatives may reasonably request to qualify the Offered Securities for

offering and sale under the securities laws of such jurisdictions, both domestic and international, as the Representatives may reasonably request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be reasonably necessary to complete the distribution of the Offered Securities; provided that in connection therewith neither the Company nor any of its subsidiaries shall be required to qualify as a foreign corporation or a dealer in securities in any jurisdiction in which it is not now so qualified or to take any action that would subject it to general consent to service of process or taxation in any jurisdiction in which it is not otherwise subject.

The Company will prepare a final term sheet, containing solely a description of the Offered Securities, substantially in the form attached hereto as Exhibit A, and the Company will file such term sheet pursuant to Rule 433(d) within the time required by such Rule.

The Company acknowledges that the Underwriters’ 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 Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering of the Offered Securities that differ from the views of the Underwriters’ respective investment bankers. The Company acknowledges that each of the Underwriters 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 Company.

The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter, or to any affiliate, director, officer, employee or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its directors, officers, partners, members and employees and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, or any such director, officer, partner, member, employee or controlling person may become subject, under the Securities 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 in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, 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 Underwriter furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for

inclusion therein, which information consists solely of the information specified in Section 8(e), and shall reimburse the Company and any such director, officer, employee or controlling person for any legal or other expenses reasonably incurred by the Company or any such director, officer, partner, member, 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 which any Underwriter may otherwise have to the Company or any such director, officer, partner, member, 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 which 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 which 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 Representatives shall have the right to employ separate counsel to represent jointly the Representatives and those other Underwriters and their respective affiliates, 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 Underwriters against the Company under this Section 8 if, in the reasonable judgment of the Representatives, it is inadvisable based upon advice of counsel for the Representatives and those Underwriters, affiliates, directors, officers, employees and controlling persons to be represented by counsel representing the Company due to actual or potential differing interests between any of the Underwriters on the one hand and the Company on the other hand, and, in that event, the reasonable fees and expenses of not more than one such separate counsel (in addition to not more than one separate counsel in any jurisdiction in which the Underwriters require representation by separate counsel in respect of such claims) shall be paid by the Company. 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 (A) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (B) does not include any findings of fact or admissions of fault or culpability as to the 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 of 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 to the extent provided in this Section 8.

(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 paragraphs (a) or (b) of this Section 8 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 appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Offered Securities 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 the Underwriters, on the other hand, with respect to the statements or omissions which 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, on the one hand, and the Underwriters, on the other hand, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Offered Securities purchased under this Agreement (before deducting expenses) received by the Company, respectively, on the one hand, and the total discounts and commissions received by the Underwriters with respect to the Offered Securities purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Offered Securities 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 or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters 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 Underwriters were treated as one entity for such purpose) or by any other method of allocation which 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 or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter exceeds the amount of any damages which such Underwriter 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Company acknowledges that (i) the statement with respect to the delivery of the Offered Securities by the Underwriters set forth on the cover page of the Prospectus and (ii) the statements set forth in (1) the third paragraph, (2) the first, second, third, fourth, fifth and sixth sentences in the seventh paragraph, (3) the third sentence of the ninth paragraph, and (4) the eleventh paragraph, under the caption “Underwriting (Conflicts of Interest)” of the Prospectus are correct and constitute the only information concerning the Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

9. Defaulting Underwriters. If any Underwriter defaults in its obligations to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Underwriter agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any Underwriter, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriter agreed but failed to purchase. If any Underwriter so defaults and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the Representatives and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10 hereof and except that the Company will continue to be liable to the non-defaulting Underwriter or Underwriters for the payment of expenses to the extent set forth in Section 6 and Section 12 hereof. As used in this Agreement, the term “Underwriter” includes (along with the parties mentioned in Schedule 1) for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 9,

purchases Offered Securities which a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default, including liability of any defaulting Underwriter for expenses referred to in Section 12 hereof. If other Underwriters are obligated or agree to purchase the Offered Securities of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven (7) full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Underwriters by written notice given to and received by the Company prior to delivery of and payment for the Offered Securities if, prior to that time, any of the events described in Section 7(l), Section 7(m) or Section 7(n) shall have occurred or if the Underwriters shall decline to purchase the Offered Securities for any reason permitted under this Agreement.

11. No Fiduciary Duty. Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters or the Company, the Underwriters and the Company acknowledge and agree that in connection with this offering, the sale of the Offered Securities or any other services the Underwriters may be deemed to be providing hereunder:

(a) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists;

(b) the Underwriters are not acting as agents of, or advisors, experts or otherwise to, the Company, including, without limitation, with respect to the determination of the public offering price of the Offered Securities;

(c) the relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations;

(d) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and

(e) the Underwriters and their respective affiliates may have interests that differ from those of the Company.

The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty.

12. Reimbursement of Underwriters’ Expenses. If the Company shall fail to tender the Offered Securities for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company shall reimburse the Underwriters for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Offered Securities, and upon demand the Company shall pay the full amount thereof to the Representatives. Notwithstanding the preceding sentence, if this Agreement is terminated pursuant to Section 10 hereof by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

13. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof.

The respective indemnities, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Offered Securities and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

16. Definition of the Terms “Business Day” and “Subsidiary.”
