1. Representations and Warranties. The Company represents and warrants to the Underwriters, as of the date hereof, as follows:

(a) Registration Statement and the Prospectus. The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-139086) under the Securities Act of 1933, as amended (the “1933 Act”), (including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A, Rule 430B or Rule 430C under the 1933 Act, the “Registration Statement”) in respect of, among other things, the Securities. The Company meets the requirements for use of Form S-3 under the 1933 Act. If the Company files a registration statement with the Commission pursuant to Rule 462(b) of the rules and regulations under the 1933 Act, then all references to the Registration Statement shall also be deemed to include that Rule 462(b) registration statement. The Registration Statement became effective, and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “1939 Act”). The prospectus included in the Registration Statement on December 1, 2006, is hereinafter referred to as the “Base Prospectus.” The Base Prospectus, as supplemented by the final prospectus supplement dated December 6, 2006 specifically relating to the Securities in the form filed with the Commission pursuant to Rule 424(b) is hereinafter referred to as the “Prospectus,” and the term “Preliminary Prospectus” means the preliminary form of the Prospectus dated December 5, 2006. For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the 1933 Act, and “Time of Sale Information” means the Preliminary Prospectus as supplemented by the free writing prospectuses, if any, each identified in Annex A hereto. As used herein, the terms “Registration Statement,” “Base Prospectus,” “Preliminary Prospectus,” “Time of Sale Information” and “Prospectus” shall include the documents, if any, incorporated by reference therein. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Time of Sale Information and the Prospectus shall be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”), after the date of this Underwriting Agreement, or the issue date of the Base Prospectus, the Preliminary Prospectus, the Time of Sale Information or the Prospectus, as the case may be, deemed to be incorporated therein by reference.

The Registration Statement and the Indenture, at the time and date the Registration Statement initially became effective, complied in all material respects with the applicable provisions of the 1933 Act and the 1939 Act, respectively, and the applicable rules and regulations of the Commission thereunder. The Registration Statement, at the time and date it initially became effective, did not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Time of Sale Information, at December 6, 2006, did not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus, at the date it is filed with, or transmitted for filing to, the Commission pursuant to Rule 424 and on each Closing Time, will comply, in all material respects, with the applicable provisions of the 1933 Act and will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to (i) that part of the Registration Statement which shall constitute the Statement of Eligibility and Qualification (Form T-1) of the Trustee under the 1939 Act or (ii) the information contained in or omitted from the Registration Statement, the Preliminary Prospectus, the Time of Sale Information or the

Prospectus or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of any Underwriter through the Representatives specifically for use in the Registration Statement, the Preliminary Prospectus, the Time of Sale Information or the Prospectus or any amendment thereof or supplement thereto.

(b) Issuer Free Writing Prospectus. The Company (including its agents and representatives, other than the Underwriters in their capacity as such) has not made, used, prepared, authorized, approved or referred to and will not prepare, make, use, authorize, approve or refer to any free writing prospectus other than the documents listed on Annex A hereto and other written communications, a copy of which has been furnished to the Representatives and to which the Representatives have not reasonably objected. Any such free writing prospectus as of its issue date complied in all material respects with the requirements of the 1933 Act and the rules and regulations thereunder and was filed with the Commission in accordance with the 1933 Act (to the extent required pursuant to Rule 433(d) thereunder).

(c) Incorporated Documents. The documents incorporated in the Registration Statement, the Time of Sale Information and the Prospectus, at the time they were (or hereafter, until each Closing Time, are) filed with the Commission, complied and will comply, as the case may be, in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”).

(d) Independent Accountants. The accountants who certified the financial statements and any supporting schedules thereto included in the Registration Statement, the Time of Sale Information and the Prospectus are independent public accountants with respect to the Company as required by the 1933 Act and the applicable rules and regulations of the Commission thereunder (the “1933 Act Regulations”) and the Public Company Accounting Oversight Board.

(e) Financial Statements. The financial statements of the Company included in the Registration Statement, the Time of Sale Information and the Prospectus, together with the related schedules and notes, as well as those financial statements, schedules and notes of any other entity included therein, present fairly the financial position of the Company in all material respects at the dates indicated, and the statement of operations, stockholders’ equity and cash flows of the Company for the periods specified. Such financial statements have been prepared in conformity with generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods involved. The supporting schedules, if any, included in the Registration Statement, the Time of Sale Information and the Prospectus present fairly, in all material respects, in accordance with GAAP the information required to be stated therein. The summary financial data for the Company, the summary unaudited pro forma combined financial data and the ratio of earnings to fixed charges included in the Registration Statement, the Time of Sale Information and the Prospectus present fairly, in all material aspects, the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included in the Registration Statement, the Time of Sale Information and the Prospectus. In addition, any pro forma financial statements of the Company and its subsidiaries and the related notes thereto included in the Registration Statement, the Time of Sale Information and the Prospectus present fairly, in all material aspects, the information shown therein, have been prepared in accordance with the Commission’s rules and guidelines with

respect to pro forma financial statements and have been properly compiled on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein.

(f) No Material Adverse Change in Business. Since the respective dates as of which information is given in the Time of Sale Information, except as otherwise stated therein, (A) there has been no material adverse change in the financial condition, results of operations or business affairs of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business (a “Material Adverse Effect”), and (B) there have been no material transactions entered into by the Company other than transactions contemplated by the Time of Sale Information or transactions arising in the ordinary course of business.

The Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failures to so qualify or be in good standing would not in the aggregate result in a Material Adverse Effect.

(h) Good Standing of Designated Subsidiaries. Each “significant subsidiary” of the Company (as such term is defined in Rule 1-02 of Regulation S-X promulgated under the 1933 Act), if any, has been duly organized and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Time of Sale Information and the Prospectus and is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failures to so qualify or be in good standing would not in the aggregate result in a Material Adverse Effect.

The Securities, when issued and authenticated in the manner provided for in the Indenture and delivered against payment of the consideration therefor specified in this Underwriting Agreement, will have been duly executed, authenticated, issued and delivered and will constitute valid and legally binding obligations of the Company entitled to the benefits of the Indenture, enforceable against the Company in accordance with their terms, except as (i) the enforceability thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and (ii) rights of acceleration, if any, and the availability of equitable remedies

may be limited by equitable principles of general applicability (regardless of whether considered in a proceeding in equity or at law).

(m) Absence of Defaults and Conflicts. The issue and sale of the Securities and compliance by the Company with all of the provisions of the Securities, the Indenture and this Underwriting Agreement and the consummation of the transactions contemplated herein and therein do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound, or to which any of the assets, properties or operations of the Company or any of its subsidiaries is subject, nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any of its subsidiaries or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its subsidiaries or any of their assets, properties or operations, except, in any such case, for such conflicts, breaches or violations as would not individually or in the aggregate result in a Material Adverse Effect. As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its subsidiaries.

(p) Investment Company Act. The Company is not, and upon the issuance and sale of the Securities as herein contemplated and the application of the net proceeds therefrom as described in the Time of Sale Information and the Prospectus will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended (the “1940 Act”).

(r) Disclosure Controls. The Company and its subsidiaries maintain an effective system of “disclosure controls and procedures” (as defined in Rule 13a-15(e) of the 1934 Act) that is designed to ensure that information required to be disclosed by the Company in reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, including controls and procedures designed to ensure that such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions regarding required disclosure.

(u) Status under the Securities Act. The Company is not an ineligible issuer, as defined under the Securities Act, at the times specified in the Securities Act in connection with the offering of the Securities.

(a) Securities. Subject to the terms and conditions set forth herein, (a) the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the price set forth in Schedule 2 hereto, the aggregate principal amount of the Firm Securities set forth in Schedule 1 hereto opposite the name of such Underwriter plus any additional principal amount of the Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, and (b) in the event and to the extent that the Underwriters shall exercise any election to purchase Additional Securities as provided below, the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the price set forth in Schedule 2 hereto plus accrued interest, if any, from the First Closing Time (as defined below) to the applicable Option Closing Time (as defined below), such accrued interest to be calculated in the same manner and at the same rate at which interest accrues on the Notes in accordance with their terms and the terms of the Indenture, the aggregate principal amount of the Additional Securities as to which such election shall have been exercised determined by multiplying such aggregate principal amount of the Additional Securities by a fraction the numerator of which is the maximum aggregate principal amount of the Additional Securities which such Underwriter is entitled to purchase as set forth opposite the name of such Underwriter in Schedule 1 hereto and the denominator of which is the maximum aggregate principal amount of the Additional Securities that all of the Underwriters are entitled to purchase hereunder.

The Company hereby grants to the Underwriters the right to purchase at their election up to $112,500,000 aggregate principal amount of Additional Securities, at the price set forth in the paragraph above, for the sole purpose of covering sales of Senior Notes due 2055 in excess of the aggregate principal amount of the Firm Securities. Any such election to purchase Additional Securities may be exercised from time to time by written notice from you to the Company, given within a period of 30 calendar days after the date of this Agreement and setting forth the aggregate principal amount of the Additional Securities to be purchased and the date on which such Additional Securities are to be delivered, as determined by you but in no event earlier than the First Closing Time or, unless you and the Company otherwise agree in writing, earlier than two or later than ten business days after the date of such notice.

(b) Payment. Payment of the purchase price for, and delivery of, the Firm Securities shall be made at the offices of the Company, 1515 Broadway, New York, New York 10036, or at such other place as shall be agreed upon by the Representatives and the Company, at 9:00 A.M. (Eastern time) on December 13, 2006 (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called the “First Closing Time”), and with respect to the Additional Securities at the offices of the Company, or at such other place as shall be agreed upon by the Representatives and the Company, at 9:00 A.M. (Eastern time) on the date specified by the Representatives in

each written notice given by the Representatives of the Underwriters’ election to purchase Additional Securities (each such time and date of payment and delivery, if not the First Closing Time, being herein called an “Option Closing Time,” and each such time and date for delivery is herein called a "Closing Time").

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Representatives for the respective accounts of the Underwriters of the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Securities which it has severally agreed to purchase. The Representatives, individually and not as representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Securities to be purchased by any Underwriter whose funds have not been received by a Closing Time, but such payment shall not relieve such Underwriter from its obligations hereunder. Delivery of the Securities shall be made through the facilities of the Depository Trust Company (“DTC”), Clearstream Luxembourg Banking, societe anonyme, or Euroclear Bank S.A./N.V., as operator of the Euroclear System, unless the Representatives shall otherwise instruct.

(c) Certain Restrictions. Each Underwriter agrees that it will not offer, sell or deliver any of the Securities, directly or indirectly, or distribute the Time of Sale Information or the Prospectus or any other offering material relating to the Securities, in or from any jurisdiction except under circumstances that will result in compliance with the applicable laws and regulations thereof and which will not impose any obligations on the Company except as set forth in this Underwriting Agreement.

(d) Free Writing Prospectuses. Each Underwriter represents and agrees that, other than the final term sheet substantially in the form of Annex B hereto, without the prior consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute a free writing prospectus. Notwithstanding anything to the contrary herein, the Company consents to the use by any Underwriter of a free writing prospectus that contains only (i) information describing only the preliminary terms of the Securities or their offering and that is within the categories of information to be included in the final term sheet of the Company attached hereto as Annex B, or (ii) other information that is not “issuer information,” as defined in Rule 433 under the 1933 Act.

3. Covenants of the Company. The Company covenants with each Underwriter, as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will comply with the requirements of Rule 430A, 430B or 430C of the 1933 Act Regulations and Rule 462(b) of the 1933 Act Regulations, if and as applicable, will file any free writing prospectus to the extent required by Rule 433 under the 1933 Act, and will notify the Representatives immediately, and confirm the notice in writing, of (i) the effectiveness of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Prospectus, (ii) the receipt of any comments from the Commission with respect to the Registration Statement, the Prospectus or the Time of Sale Information, (iii) any request by the Commission for any amendment to the Registration

Statement or any amendment or supplement to the Prospectus or for additional information, and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of the Prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as it deems necessary to ascertain promptly whether the Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, it will promptly file the Prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. Prior to each Closing Time, the Company will advise the Representatives promptly of its intention to file or prepare any amendment to the Registration Statement, any amendment, supplement or revision to the Prospectus, or any free writing prospectus in relation to the Securities, will furnish the Representatives with copies of any such documents or communications a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object on a timely basis, unless, in the judgment of the Company or its counsel, such amendment or supplement or other document or communication is necessary to comply with any law.

The Company has furnished or, if requested in writing by the Representatives, will deliver to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, one conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters.

If at any time when the Prospectus is required by the 1933 Act or the 1934 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Company, after consultation with counsel for the Underwriters, to amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or to amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to

make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of counsel for the Company, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the Time of Sale Information or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect for so long as required for the distribution of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(g) Earnings Statement.

(j) Record Retention. The Company will, to the extent required under Rule 433 under the 1933 Act, retain copies of each free writing prospectus that it has used and not filed with the Commission.

4. Payment of Expenses. The Company will pay all expenses incident to the performance of its obligations under this Underwriting Agreement, including (i) the preparation, printing and filing of the Registration Statement (including financial statements and any schedules or exhibits and any document incorporated therein by reference) as originally filed and of each amendment or supplement thereto, (ii) the preparation, printing and delivery to the Underwriters of this Underwriting Agreement, any agreement among Underwriters, the Indenture and such other documents as may be required in connection with the offering,

(h) Additional Documents. At each Closing Time, counsel for the Underwriters shall have been furnished with such documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the Securities as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Securities as herein contemplated shall be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in the Time of Sale Information, the Prospectus (or any amendment or supplement thereto), any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the 1933 Act, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense as reasonably incurred (including the fees and disbursements of counsel chosen by the Representatives), in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense (A) to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or the Time of Sale Information, the Prospectus (or any amendment or supplement thereto), or any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the 1933 Act; or (B) to the extent arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon Form T-1 under the 1939 Act filed as an exhibit to the Registration Statement.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), the Time of Sale Information, the Prospectus (or any amendment or supplement thereto), or any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the 1933 Act in reliance upon and in conformity with written information furnished to the

Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), the Time of Sale Information, the Prospectus (or any amendment or supplement thereto), or such free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the 1933 Act. This indemnity agreement will be in addition to any liabilities which any Underwriter may otherwise have.

(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding 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) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is 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 Securities pursuant to this Underwriting Agreement or (ii) if the allocation provided by clause (i) 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 of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, 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, in connection with the offering of the Securities under this Underwriting Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Securities (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such 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 by the Underwriters and the parties’ relative intent, 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 contribution pursuant to this Section 7 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 which does not take account of the equitable considerations referred to above in this Section. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased and sold by it hereunder exceeds the amount of any damages which 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the

Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule 1 hereto, and not joint.

8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Underwriting Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of and payment for the Securities.

(a) Underwriting Agreement. The Representatives may terminate this Underwriting Agreement, by notice to the Company, at any time at or prior to a Closing Time, if (i) there has been, since the time of execution of this Underwriting Agreement or since the respective dates as of which information is given in the Time of Sale Information, any material adverse change in the financial condition, results of operations or business affairs of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) there has occurred any material adverse change in the financial markets in the United States or, if the Securities include securities denominated or payable in, or indexed to, one or more foreign or composite currencies, in the international financial markets, or any outbreak of hostilities or escalation thereof or other calamity or crisis or any material change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange or the American Stock Exchange, or if trading generally on the New York Stock Exchange or the American Stock Exchange has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority or (iv) a banking moratorium has been declared by either Federal or New York authorities or, if the Securities include securities denominated or payable in, or indexed to, one or more foreign or composite currencies, by the relevant authorities in the related foreign country or countries.

(b) Liabilities. If this Underwriting Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 6, 7, 8, 9(b) and 10 shall survive such termination and remain in full force and effect.

10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at a Closing Time to purchase the Securities which it or they are obligated to purchase at such Closing Time under this Underwriting Agreement (the “Defaulted Securities”), then the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less

than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the number or aggregate principal amount, as the case may be, of Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities set forth on Schedule 1 hereto, the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters or in such other proportions as the Representatives may specify, or

(b) if the number or aggregate principal amount, as the case may be, of Defaulted Securities exceeds 10% of the aggregate principal amount of Securities set forth on Schedule 1 hereto, the non-defaulting Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such non-defaulting Underwriters do not purchase all the Securities, this Underwriting Agreement will terminate without liability to any non-defaulting Underwriter or the Company; provided, however, that, for avoidance of doubt, in the case of such a termination on account of a default with respect to Additional Securities, this Agreement shall not terminate as to the Firm Securities purchased by the Underwriters from the Company pursuant hereto prior to such termination.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Underwriting Agreement, either the Representatives or the Company shall have the right to postpone a Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements.

11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication, excluding e-mail. Notices to the Underwriters shall be directed to the Representatives c/o Wachovia Securities, One Wachovia Center, DC-6, 301 South College Street, Charlotte, NC 28288, attention: Syndicate Operations; and notices to the Company shall be directed to it at Viacom Inc., 1515 Broadway, New York, New York 10036, attention of General Counsel.

12. Parties. This Underwriting Agreement shall inure to the benefit of and be binding upon the Company, the Representatives and the other Underwriters and their respective successors. Nothing expressed or mentioned in this Underwriting Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Underwriting Agreement or any provision herein contained. This Underwriting Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective

successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

13. GOVERNING LAW. THIS UNDERWRITING AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF.

14. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

15. Counterparts. This Underwriting Agreement may be executed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were on the same instrument.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this Underwriting Agreement, along with all counterparts, will become a binding agreement among each of the Underwriters and the Company in accordance with its terms.
