On the basis of the representations, warranties and covenants contained in, and subject to the terms and conditions of, this Agreement, the Company agrees to sell the Firm Notes to the several Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase from the Company, at a purchase price of 97.50% of the principal amount thereof, the principal amount of Firm Notes set forth opposite that Underwriter’s name in Schedule 1 hereto plus any additional principal amount of Notes which such Underwriter may become obligated to purchase pursuant to the provisions of Section 9 hereof. Each Underwriter shall be obligated to purchase from the Company, the principal amount of the Firm Notes that represents the same proportion of the principal amount of the Firm Notes to be sold by the Company as the principal amount of the Firm Notes set forth opposite the name of such Underwriter in Schedule 1 plus any additional principal amount of Notes which such Underwriter may become obligated to purchase pursuant to the provisions of Section 9 hereof represents of the aggregate principal amount of the Firm Notes to be purchased by all of the Underwriters pursuant to this Agreement. The respective purchase obligations of the Underwriters with respect to the Firm Notes shall be rounded among the Underwriters to avoid fractional Notes, as the Representatives may determine.

In addition, the Company grants to the Underwriters an option to purchase up to an aggregate principal amount of $45,000,000 Additional Notes at a purchase price of 97.50% of the principal amount thereof. Such options are exercisable only for the purpose of covering overallotments made in connection with the offering and distribution of the Firm Notes and as set forth in Section 4 hereof. Each Underwriter agrees, severally and not jointly, to purchase the principal amount of Additional Notes (subject to such adjustments to eliminate fractional Notes as the Representatives may determine) that bears the same proportion to the aggregate principal amount of Additional Notes to be sold on such Delivery Date as the principal amount of Firm Notes set forth in Schedule 1 hereto opposite the name of such Underwriter bears to the aggregate principal amount of Firm Notes.

The Company shall not be obligated to deliver any Firm Notes or Additional Notes to be delivered on the applicable Delivery Date, except upon payment for all such Notes to be purchased on such Delivery Date as provided herein.

3. Offering of Notes by the Underwriters. Upon authorization by the Representatives of the release of the Firm Notes, the several Underwriters propose to offer the Firm Notes for sale upon the terms and conditions to be set forth in the Prospectus.

4. Delivery of and Payment for the Notes. Delivery of and payment for the Notes shall be made at 10:00 A.M., New York City time, on the fourth full business day following the date of this Agreement or at such other date or place as shall be determined by agreement between the Representatives and the Company or as provided in Section 9 hereof. This date and time are sometimes referred to as the “Initial Delivery Date.” Delivery of the Firm Notes shall be made to the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives and of the respective aggregate purchase prices of the Firm Notes being sold by the Company to or upon the order of the Company of the purchase price by wire transfer in immediately available funds to the accounts specified by the Company.

The options granted in Section 2 will expire 30 days after the date of this Agreement and may be exercised in whole or from time to time in part by written notice being given to the Company by the Representatives; provided that if such date falls on a day that is not a business day, the options granted in Section 3 will expire on the next succeeding business day. Such notice shall set forth the aggregate principal amount of Additional Notes as to which the options are being exercised and the date and time, as determined by the Representatives, when the Additional Notes are to be delivered; provided, however, that this date and time shall not be earlier than the Initial Delivery Date nor earlier than the second business day after the date on which the options shall have been exercised nor later than the fifth business day after the date on which the options shall have been exercised or as provided in Section 9 hereof. Each date and time the Additional Notes are delivered is sometimes referred to as an “Additional Notes Delivery Date,” and the Initial Delivery Date and any Additional Notes Delivery Date are sometimes each referred to as a “Delivery Date.”

Delivery of the Additional Notes by the Company and payment for the Additional Notes by the several Underwriters through the Representatives shall be made at 10:00 A.M., New York City time, on the date specified in the corresponding notice described in the preceding paragraph or at such other date or place as shall be determined by agreement between the Representatives and the Company. On the Additional Notes Delivery Date, the Company shall deliver or cause to be delivered the Additional Notes to the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives and of the respective aggregate purchase prices of the Additional Notes being sold by the Company to or upon the order of the Company of the purchase price by wire transfer in immediately available funds to the accounts specified by the Company.

The Notes will be delivered to Underwriters, or the Trustee as custodian for The Depository Trust Company (“DTC”), against payment by or on behalf of the Underwriters of the purchase price therefor by wire transfer in immediately available funds, by causing DTC to credit the Notes to the account of the Underwriters at DTC. The Notes will be evidenced by one or more global securities in definitive form (the “Global Notes”) or by additional definitive securities, and will be registered, in the case of the Global Notes, in the name of Cede & Co. as nominee of DTC, and in the other cases, in such names and in such denominations as the Underwriters shall request prior to 10:00 A.M., New York City time, on the second business day preceding the Initial Delivery Date or the Additional Notes Delivery Date, as the case may be. The Notes to be delivered to the Underwriters shall be made available to the Underwriters in New York City for inspection and packaging not later than 10:00 A.M., New York City time, on the business day next preceding the Initial Delivery Date or the Additional Notes Delivery Date, as the case may be.

(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 (through the forfeiture of substantive rights and defenses) 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 indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties 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 under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time after notice of the institution of such action to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party and in the judgment of counsel to the indemnified party it is advisable to employ separate counsel or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate counsel (in addition to one local counsel) for all such indemnified parties except as provided in the preceding sentence. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld or delayed), 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 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 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 or delayed), 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. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(a) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 60 days prior notice of its intention to settle and the terms of such settlement.

(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 appropriate to reflect the relative benefits received by the Company and the Underwriters 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 Underwriters 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 Underwriters, 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, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Notes purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. 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(e) 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 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(e) shall be deemed to include, for purposes of this Section 8(e), 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(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Notes 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. The Underwriters’ obligations to contribute as provided in this Section 8(e) are several in proportion to their respective underwriting obligations and not joint. Each party entitled to contribution agrees that upon the service of a summons or other initial legal process upon it in any action instituted against it in respect to which contribution may be sought, it will promptly give written notice of such service to the party or parties from whom contribution may be sought, but the omission so to notify such party or parties of any such service will not relieve the party from whom contribution may be sought for any obligation it may have hereunder or otherwise (except to the same extent as specifically provided in Section 8(c) above).

(e) The Underwriters severally confirm that the statements regarding delivery of Notes by the Underwriters set forth on the cover page of, and the concession and reallowance figures and the first two paragraphs under the caption “Underwriting—Stabilization, Short Positions and Penalty Bids,” in the most recent Preliminary Prospectus and the Prospectus are correct and the Underwriters and the Company acknowledge that such information constitute the only information concerning such 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.

(a) If, on any Delivery Date, any Underwriter defaults in its obligations to purchase the Notes that it has agreed to purchase under this Agreement, the remaining non-defaulting Underwriters may in their discretion arrange for the purchase of such Notes by the non-defaulting Underwriters or other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Notes, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Notes on such terms. In the event that within the respective prescribed periods, the non-defaulting Underwriters notify the Company that they have so arranged for the purchase of such Notes, or the Company notifies the non-defaulting Underwriters that it has so arranged for the purchase of such Notes, either the non-defaulting Underwriters or the Company may postpone such Delivery 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 Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus or in any such other document or arrangement that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the principal amount of the Notes that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of Notes, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes that such Underwriter agreed to purchase hereunder plus such Underwriter's pro rata share (based on the aggregate principal amount of Notes that such Underwriter agreed to purchase hereunder) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made; provided that the non-defaulting Underwriters shall not be obligated to purchase more than 110% of the aggregate principal amount of Notes that it agreed to purchase on such Delivery Date pursuant to the terms of Section 2.

(c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount that remains unpurchased exceeds one-eleventh of the aggregate principal amount of Notes, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Sections 6 and 11 and except that the provisions of Section 8 shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives 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(k), 7(l) and 7(o) shall have occurred or if the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement.

11. Reimbursement of Underwriters’ Expenses. If (a) the Company shall fail to tender the Notes for delivery to the Underwriters for any reason or (b) the Underwriters shall decline to purchase the Notes because any condition to the obligations of the Underwriters set forth in Section 7 hereof is not satisfied or because of any termination due to any of the events described in Sections 7(k), 7(l) and 7(o) hereof, the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Underwriters) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Notes, and upon demand and presentation of reasonable supporting documentation the Company shall pay the full amount thereof to the Representatives. Notwithstanding the foregoing, if this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any Underwriter on account of those expenses.

12. Research Analyst Independence. 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 views 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 their respective investment banking divisions. 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 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 by such Underwriters’ investment banking divisions. 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 companies that may be the subject of the transactions contemplated by this Agreement.

13. No Fiduciary Duty. The Company acknowledges and agree that in connection with this offering, sale of the Notes or any other services the Underwriters 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 Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Notes, and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

14. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Notes shall be deemed to be a successor solely by reason of such purchase.

16. Survival. The respective indemnities, rights of contribution, 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 Notes 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.

17. Definition of the Terms “Business Day,” “Affiliate,” and “Subsidiary”; Actions by Representatives. For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “affiliate” and “subsidiary” have the meanings set forth in Rule 405 under the Securities Act, provided that “subsidiary” with respect to the Company shall include IMTT and its consolidated subsidiaries.

less than $66.50 per share (subject to adjustment in the same manner and at the same time as the share prices in the table above), no additional shares will be issued upon conversion.

Notwithstanding the foregoing, in no event will the total number of the Company’s Shares issuable upon conversion exceed 15.0375 per $1,000 principal amount of the Notes, subject to adjustments in the same manner as the conversion rate as set forth under “Description of the Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Prospectus.
