The Securities will be issued pursuant to an Indenture dated as of January 26, 2016 (including the terms of the Securities to be established pursuant thereto, the “Indenture”) among the Issuer, Berkshire Hathaway Finance Corporation and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”).

The Issuer hereby confirms its agreement with the Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. A registration statement on Form S-3 (Registration No. 333-209122), including a prospectus (the “Base Prospectus”) relating to the Securities, has been filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), and has become effective under the Securities Act. Such registration statement, including any prospectus supplement relating to the Securities filed with the Commission pursuant to Rule 424 under the Securities Act and any other information deemed to be part of such registration statement pursuant to Rule 430B under the Securities Act, is hereinafter referred to as the “Registration Statement.” The Base Prospectus, as supplemented by a prospectus supplement to reflect the final terms of the Securities and the offering thereof, as filed with the Commission pursuant to Rule 424 under the Securities Act, is hereinafter referred to as the “Final Prospectus.” The Base Prospectus, as supplemented by any preliminary prospectus supplement which describes the Securities and the offering thereof, as filed with the Commission pursuant to Rule 424 under the Securities Act, is hereinafter referred to as a “Preliminary Prospectus.” Any reference herein to the Registration Statement, the Base Prospectus, a Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents that were filed by the Issuer on or prior to the respective dates thereof under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”), and incorporated by reference therein, excluding any documents or portions of such documents that are deemed under the rules and regulations of the Commission under the Securities Act not to be incorporated by reference therein; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, a Preliminary Prospectus, or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act deemed to be incorporated therein by reference after the respective dates thereof.

At or prior to the time when sales of the Securities were first made (the “Time of Sale”), the Issuer had prepared the following information (the “Time of Sale Information”): a Preliminary Prospectus dated March 8, 2016, and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

2. Purchase of the Securities by the Underwriters. (a) On the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, the Issuer agrees to issue and sell the Securities to each Underwriter as provided in this Agreement, and each Underwriter, severally and not jointly, agrees to purchase from the Issuer the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to (i) with respect to the 2021 Notes, 99.463% of the principal amount thereof, plus accrued interest, if any, from March 15, 2016 to the Closing Date (as defined below), (ii) with respect to the 2023 Notes, 99.353% of the principal amount thereof, plus accrued interest, if any, from March 15, 2016 to the Closing Date and (iii) with respect to the 2026 Notes, 99.481% of the principal amount thereof, plus accrued interest, if any, from March 15, 2016 to the Closing Date. The Issuer will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

2

(b) The Issuer understands that the Underwriters intend to make a public offering of the Securities as soon as practicable after the effectiveness of this Agreement as in the judgment of the Underwriters is advisable, and initially to offer the Securities on the terms set forth in the Final Prospectus. The Issuer acknowledges and agrees that each Underwriter may offer and sell Securities to or through any affiliate of such Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through the applicable Underwriter.

(c) Payment for and delivery of the Securities will be made at the offices of Simpson Thacher & Bartlett LLP at 10:30 A.M., New York City time, on March 15, 2016, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Underwriters and the Issuer may agree upon in writing. The time and date of such payment and delivery is referred to herein as the “Closing Date”.

(d) Payment for the Securities shall be made by wire transfer in immediately available funds to the account(s) specified to the Underwriters by the Issuer against delivery to the nominee of The Depository Trust Company, for the account of the Underwriters, of one or more global notes representing the Securities (collectively, the “Global Notes”), with any transfer taxes payable in connection with the sale of the Securities duly paid by the Issuer, except to the extent such taxes were imposed due to the failure of an Underwriter, upon the request of the Issuer, to use its reasonable efforts to provide any form, certificate, document or other information that would have reduced or eliminated the withholding or deduction of such taxes. The Global Notes will be made available for inspection by the Underwriters not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date.

(e) The Issuer acknowledges and agrees that each Underwriter is acting solely in the capacity of an arm’s length contractual counterparty to the Issuer with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Issuer or any other person. Additionally, the Underwriters are not advising the Issuer or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Issuer shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Issuer with respect thereto. Any review by the Underwriters of the Issuer, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Issuer.

3. Representations and Warranties of the Issuer. The Issuer represents and warrants to each Underwriter that:

(a) Time of Sale Information. The Time of Sale Information at the Time of Sale did not, and at the Closing Date will 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; provided that the Issuer makes no representation and warranty with respect to any statements or omissions made in reliance upon

(o) No Stabilization or Manipulation. Prior to the date hereof, neither the Issuer nor any of its affiliates has taken any action which is designed to or which has constituted or which might have been expected to cause or result in stabilization or manipulation of the price of any security of the Issuer in connection with the offering of the Securities.

(q) No Violation or Default. Neither the Issuer nor any Significant Subsidiary is (i) in violation of its Certificate of Incorporation or Restated Certificate of Incorporation (as the case may be) or By-laws or (ii) in default in the performance or observance of any material obligation, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound, except in the case of clause (i) for any immaterial violation of its By-laws or in the case of clause (ii) where such violation would not reasonably be expected to have a Material Adverse Effect.

(r) Legal Proceedings. Except as described in the Registration Statement, the Time of Sale Information and the Final Prospectus, there are no legal or governmental proceedings pending to which the Issuer or any of the Significant Subsidiaries is a party or of which any property of the Issuer or any of the Significant Subsidiaries is the subject which, if determined

7

adversely to the Issuer or any Significant Subsidiary, would individually or in the aggregate have a Material Adverse Effect; and, to the best of the Issuer’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

(s) Investment Company Act. The Issuer is not, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof, will not be, an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”).

(t) Independent Accountants. To the best of the Issuer’s knowledge, Deloitte & Touche LLP, who have certified the consolidated financial statements of the Issuer included in the Registration Statement, is an independent registered public accounting firm as required by the Securities Act and the rules and regulations of the Commission and the Public Company Accounting Oversight Board thereunder.

(u) Accounting Controls. The Issuer maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) that complies with the requirements of the Exchange Act and has been designed by the Issuer’s principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Issuer’s internal control over financial reporting is effective and the Issuer is not aware of any material weaknesses in its internal control over financial reporting in each case as of the end of the most recent fiscal year of the Issuer.

(v) Disclosure Controls. The Issuer maintains “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) of the Exchange Act) that comply with the requirements of the Exchange Act; such disclosure controls and procedures have been designed to ensure that material information relating to the Issuer and its consolidated subsidiaries is made known to the Issuer’s principal executive officer and principal financial officer by others within those entities; such disclosure controls and procedures are effective.

(w) No Material Change in the Issuer’s Internal Control over Financial Reporting. Since the date of the latest audited financial statements included or incorporated by reference in the Registration Statement, there has been no change in the Issuer’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Issuer’s internal control over financial reporting.

(x) Status under the Securities Act. The Issuer is not an ineligible issuer and is a well-known seasoned issuer, in each case as defined under the Securities Act, in each case at the times specified in the Securities Act in connection with the offering of the Securities.

4. Further Agreements of the Issuer. The Issuer covenants and agrees with each Underwriter that:

8

The Issuer will pay the registration fees for this offering within the time period required by Rule 456(b)(1)(i) under the Securities Act (without giving effect to the proviso therein) and in any event prior to the Closing Date.

(b) Delivery of Copies. The Issuer will deliver, without charge to the Underwriters (during the Prospectus Delivery Period (as defined below), as many copies of the Final Prospectus (including all amendments and supplements thereto)) and each Issuer Free Writing Prospectus as the Underwriters may reasonably request. As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Securities as in the opinion of counsel for the Underwriters a prospectus relating to the Securities is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Securities by any Underwriter or dealer; provided that the Underwriters shall promptly notify the Issuer of the termination of the Prospectus Delivery Period.

(c) Amendments or Supplements; Issuer Free Writing Prospectuses. Prior to the termination of the offering of the Securities, before using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, and before filing any amendment or supplement to the Registration Statement or the Final Prospectus, whether before or after the time that the Registration Statement becomes effective, the Issuer will furnish to the Underwriters and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or file any such proposed amendment or supplement to which the Underwriters reasonably object.

(d) Notice to the Underwriters. From the date hereof until the end of the Prospectus Delivery Period, the Issuer will advise the Underwriters promptly, and confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective; (ii) when any supplement to the Final Prospectus or any amendment to the Final Prospectus or any Issuer Free Writing Prospectus has been filed; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Final Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information relating thereto; (iv) when it learns of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any

9

Preliminary Prospectus or the Final Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (v) when it learns of the occurrence of any event as a result of which the Final Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Final Prospectus, the Time of Sale Information or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vi) of the receipt by the Issuer of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act; and (vii) of the receipt by the Issuer of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Issuer will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Final Prospectus or suspending any such qualification of the Securities and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(e) Time of Sale Information. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any 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, not misleading or (ii) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Issuer will promptly notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Underwriters may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

(f) Ongoing Compliance. If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Final Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Final Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Final Prospectus to comply with law, the Issuer will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Underwriters may designate, such amendments or supplements to the Final Prospectus as may be necessary so that the statements in the Final Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Final Prospectus is delivered to a purchaser, be misleading or so that the Final Prospectus will comply with law.

10

(g) Blue Sky Compliance. The Issuer will promptly from time to time take such action as the Underwriters may reasonably request to qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Underwriters shall reasonably request and will continue such qualifications in effect so long as required to complete the distribution of the Securities; provided that the Issuer shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) take any action that would subject it to taxation in any such jurisdiction if it is not otherwise so subject.

(h) Earning Statement. The Issuer will make generally available to its security holders an earning statement (that need not be audited) that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning with the first fiscal quarter of the Issuer occurring after the “effective date” (as defined in Rule 158) of the Registration Statement.

(i) Clear Market. The Issuer, during the period beginning from the date hereof and continuing until the Closing Date, will not offer, sell, contract to sell or otherwise dispose of, except as provided hereunder, any securities of the Issuer that are substantially similar to the Securities, including but not limited to any securities that represent the right to receive the Securities or any such substantially similar securities, without the Underwriters’ prior written consent, other than any securities that have been identified to the Underwriters in writing prior to the date hereof.

(j) Use of Proceeds. The Issuer will use the net proceeds received by the Issuer from the sale of the Securities pursuant to this Agreement in the manner specified in the Registration Statement, the Time of Sale Information and the Final Prospectus under the caption “Use of Proceeds”.

(l) Record Retention. The Issuer will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

5. Certain Agreements of the Underwriters. Each Underwriter hereby represents and agrees that:

(a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Issuer and not incorporated by reference into the Registration Statement and any press release issued by the Issuer) other than (i) a free writing prospectus that, solely as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus listed on Annex A or prepared pursuant to Section 3(c) or Section 4(c) above (including any electronic road show), or (iii) any

11

free writing prospectus prepared by such Underwriter and approved by the Issuer in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus”). Notwithstanding the foregoing, the Underwriters may use a term sheet in the form of Annex B hereto without the consent of the Issuer.

(b) It is not subject to any pending proceeding under Section 8A of the Securities Act with respect to the offering (and will promptly notify the Issuer if any such proceeding against it is initiated during the Prospectus Delivery Period).

(c) (i) It has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000 (the “FSMA”)) received by it in connection with the issue or sale of the Securities in circumstances in which Section 21(1) of the FSMA is complied with or does not apply; and (ii) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the Securities in, from or otherwise involving the United Kingdom.

(d) In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State, it has not made and will not make an offer of Securities to the public in that Relevant Member State other than:

(i) to any legal entity which is a “qualified investor” as defined in the Prospectus Directive;

(ii) to fewer than 150 natural or legal persons (other than “qualified investors” as defined in the Prospectus Directive), subject to obtaining the prior consent of the relevant dealer or dealers nominated by the Issuer for any such offer; or

(iii) in any other circumstances falling within Article 3(2) of the Prospectus Directive,

provided that no such offer of Securities shall result in a requirement for the Issuer or any Underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive or a supplemental prospectus pursuant to Article 16 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer of Securities to the public” in relation to any Securities in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Securities to be offered so as to enable an investor to decide to purchase or subscribe for the Securities, as the same may be varied in that Relevant Member State by any measure implementing the Prospectus Directive in that Relevant Member State. The expression “Prospectus Directive” means Directive 2003/71/EC ( as amended, including by Directive 2010/73/EU), and includes any relevant implementing measure in the Relevant Member State.

(e) Neither it nor any of its affiliates (i) has offered or sold, or will offer or sell, in Hong Kong, by means of any document, the Securities other than (A) to “professional investors” as defined in the Securities and Futures Ordinance (Cap. 571) of Hong Kong and any rules made

12

under that Ordinance; or (B) in other circumstances which do not result in the document being a “prospectus” as defined in the Companies Ordinance (Cap. 32) of Hong Kong or which do not constitute an offer to the public within the meaning of that Ordinance or (ii) has issued or had in its possession for the purposes of issue, or will issue or have in its possession for the purposes of issue, whether in Hong Kong or elsewhere, any advertisement, invitation or document relating to the Securities that is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to the Securities that are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” as defined in the Securities and Futures Ordinance and any rules made under that Ordinance.

(f) It will not circulate or distribute the Registration Statement or any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the Securities, nor will it offer or sell, or make an invitation for subscription or purchase, the Securities, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor under Section 274 of the Securities and Futures Act, Chapter 289 of Singapore (the “SFA”), (ii) to a relevant person under Section 275(1) and/or any person under Section 275(1A) of the SFA, and in accordance with the conditions, specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA.

(g) It will not offer or sell any of the Securities, directly or indirectly in Japan or to, or for the benefit of, any Japanese person or to others, for re-offering or re-sale directly or indirectly in Japan or to any Japanese person, except in each case pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Securities and Exchange Law of Japan and any other applicable laws and regulations of Japan. For the purposes of this provision, “Japanese person” means any person resident in Japan, including any corporation or other entity organized under the laws of Japan.

(h) It will not offer, sell or deliver any of the Securities in any jurisdiction outside the United States except under circumstances that will result in compliance with the applicable laws thereof, and it will take at its own expense whatever action is required to permit its purchase and resale of the Securities in such jurisdictions. Each Underwriter understands that no action has been taken to permit a public offering of the Securities in any jurisdiction outside the United States where action would be required for such purpose, and agrees not to cause any advertisement of the Securities to be published in any newspaper or periodical or posted in any public place and not to issue any circular relating to the Securities, except in any such case at each Underwriter’s own risk and expense.

6. Conditions of Underwriters’ Obligations. The obligation of the Underwriters to purchase Securities on the Closing Date as provided herein is subject to the performance by the Issuer of its covenants and other obligations hereunder and to the following additional conditions:

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Issuer agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) or any untrue statement or alleged untrue statement of a material fact contained in the Final Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Issuer in writing by any Underwriter expressly for use therein.

(b) Indemnification of the Issuer. Each Underwriter agrees to indemnify and hold harmless the Issuer and each of its directors, officers who signed the Registration Statement and each person, if any, who controls the Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Issuer in writing by such Underwriter expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any Time of Sale Information or the Final Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the second and third sentences of the third paragraph, the third sentence of the seventh paragraph and the eighth paragraph under the caption “Underwriting (Conflicts of Interest).”

(c) Notice and Procedures. Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case

16

subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) Contribution. If the indemnification provided for in paragraphs (a) or (b) above is unavailable to an indemnified party or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer on the one hand and the Underwriters on the other from the offering of the Securities 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) but also the relative fault of the Issuer on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Issuer on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Issuer from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Final Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Issuer on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Issuer 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 or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such indemnified party in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by such Underwriter and distributed to investors were offered to investors 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

17

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 pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Defaulting Underwriter.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Issuer on the terms contained in this Agreement. If, within 48 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Issuer shall be entitled to a further period of 48 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Issuer may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Issuer or counsel for the Underwriters may be necessary in the Registration Statement and the Final Prospectus or in any other document or arrangement, and the Issuer agrees to promptly prepare any amendment or supplement to the Registration Statement and the Final Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 8 purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Issuer as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Issuer shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Issuer as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Issuer 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 8 shall be without liability on the part of the Issuer, except that the Issuer will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

18

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

9. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

10. Payment of Expenses. Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Issuer covenants and agrees with the Underwriters that it will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Issuer’s counsel and accountants in connection with the issue of the Securities and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Final Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof to the Underwriters and dealers; (ii) the cost of printing or producing or distributing each of this Agreement, the Transaction Documents, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 4(g) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities (not including the related legal fees); (vi) the fees, expenses and disbursements of the Trustee in connection with the Transaction Documents and the Securities; (vii) the costs and charges of any transfer agent and registrar; (viii) all expenses incurred by the Issuer in connection with any “road show” presentation to potential investors and (ix) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section 10. It is understood, however, that, the Underwriters will pay, except as provided in this Section 10, and Section 7 hereof, all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any advertising expenses connected with any offers they may make.

(b) If this Agreement is terminated pursuant to Section 8 hereof or if any Underwriter shall default in its obligations hereunder, or if the Underwriters shall fail to take and purchase the Securities due to the failure of the condition set forth in Section 6(c) hereof to be met, the Issuer shall not then be under any liability to any Underwriter except as provided in Section 7 hereof; but for any other reason the Securities are not delivered by or on behalf of the Issuer as provided herein, the Issuer will reimburse the Underwriters for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but the Issuer shall then be under no further liability to the Underwriters except as provided in Section 7 hereof.

11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and, solely to

19

the extent set forth in Section 7 hereof, the officers and directors and any controlling persons referred to therein, and the affiliates of each Underwriter referred to therein. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Issuer and the Underwriters contained in this Agreement or made by or on behalf of the Issuer or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Issuer or the Underwriters.

13. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

The Registration Statement became effective under the Securities Act upon filing with the Commission pursuant to Rule 462 of the Securities Act; the Indenture has been qualified under the Trust Indenture Act; the Final Prospectus was filed with the Commission in the manner and within the time period specified by Rule 424(b) under the Securities Act; and, to the knowledge of such counsel, no order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Issuer or in connection with the offering is pending or threatened by the Commission.

ii. The Registration Statement at the time it became effective, the Preliminary Prospectus and each Issuer Free Writing Prospectus included in the Time of Sale Information at the Time of Sale and the Final Prospectus as of its date (other than, in each case, the financial statements, financial and accounting data or supporting schedules (or any notes to any such statements or schedules) or other financial or statistical information included or incorporated by reference in (or omitted from) such documents, as to which such counsel need express no opinion) appear on their faces to have complied as to form in all material respects with the requirements of the Securities Act; and the Indenture appears on its face to have complied as to form in all material respects with the requirements of the Trust Indenture Act.

iii. Based solely on such counsel’s review of a certificate of good standing issued by the Secretary of State of the State of Delaware, the Issuer is validly existing as a corporation, in good standing under the laws of the state of Delaware, with the corporate power and authority to own its properties and conduct its business as described in the Registration Statement and the Final Prospectus.

v. This Agreement has been duly authorized, executed and delivered by the Issuer.

vi.

The issue and sale of the Securities, and the compliance by the Issuer with all of the provisions of the Securities, the Transaction Documents and this Agreement, and the consummation of the transactions herein and therein contemplated, will not (A) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Issuer is a party and which is identified in the officer’s certificates delivered to such counsel by the Issuer in connection with the rendering of such opinion, (B) violate the provisions of the Restated Certificate of Incorporation or By-laws (as amended through the date of such opinion) of the Issuer or (C) violate any order known to such counsel to be applicable to the Issuer of any court or governmental agency or body having jurisdiction over the Issuer, except, in the case of clauses (A) and (C) any such conflict, breach, violation, or default which would not reasonably be expected to have a Material Adverse Effect;

ix.
