Ladies and Gentlemen:

Berkshire Hathaway Finance Corporation, a Delaware corporation (the “Issuer”) and a wholly-owned subsidiary of Berkshire Hathaway Inc., a Delaware corporation (the “Guarantor”), proposes to issue and sell to Goldman, Sachs & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC (each, an “Underwriter,” and collectively, the “Underwriters”), $400,000,000 aggregate principal amount of its Floating Rate Senior Notes due 2017 (the “Notes”). The Notes will be issued pursuant to an Indenture dated as of February 1, 2010 (including the terms of the Notes to be established pursuant thereto, the “Indenture”) among the Issuer, the Guarantor and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). Each of such Notes will have the benefit of an unconditional and irrevocable guarantee (the “Guarantee”) as to the payment of principal and interest from the Guarantor. The Notes and the Guarantee are referred to collectively in this Agreement as the “Securities.”

Each of the Issuer and the Guarantor, jointly and severally, hereby confirms its agreement with the Underwriters concerning the purchase and sale of the Securities, as follows:

1

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 or the Guarantor 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 and the Guarantor had prepared the following information (the “Time of Sale Information”): a Preliminary Prospectus dated August 7, 2014, and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

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.

(b) The Issuer and the Guarantor understand 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.

Additionally, the Underwriters are not advising the Issuer or the Guarantor or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction.

(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 or the Guarantor and not incorporated by reference into the Registration Statement and any press release issued by the Issuer or the Guarantor) 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 free writing prospectus prepared by such Underwriter and approved by the Issuer and the Guarantor 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 or the Guarantor.

(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 and the Guarantor 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 any invitation or inducement to engage in investment activity (within the meaning of section 21 of the Financial Services and Markets Act 2000 (“FSMA”)) received by it in connection with the issue or sale of any Securities in circumstances in which section 21(1) of the FSMA does not apply to the Issuer or the Guarantor; 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 (the “Relevant Implementation Date”), it has not made and will not make an offer of Securities to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Securities which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of Securities to the public in that Relevant Member State at any time:

(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), as permitted under 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.

12

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 the Securities, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive), and includes any relevant implementing measure in the Relevant Member State and the expression “2010 PD Amending Directive” means Directive 2010/73/EU.

(e) In Hong Kong, it has not offered or sold the Securities by means of any document other than (i) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder; or (ii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies Ordinance (Cap. 32, Laws of Hong Kong) or which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap. 32, Laws of Hong Kong), and no advertisement, invitation or document relating to the Securities may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which 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 laws of Hong Kong) other than with respect to Securities which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.

(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 pursuant to Section 275(1A), 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 Securities, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan (which term as used herein means any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to a resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Securities and Exchange Law and any other applicable laws, regulations and ministerial guidelines 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

13

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 and the Guarantor of their respective covenants and other obligations hereunder and to the following additional conditions:

(a) No order suspending the effectiveness of the Registration Statement shall be in effect, and no proceeding for such purpose, pursuant to Rule 401(g)(2) or pursuant to Section 8A under the Securities Act shall be pending before or threatened by the Commission; each Issuer Free Writing Prospectus and Final Prospectus shall have been timely filed with the Commission under the Securities Act (in the case of an Issuer Free Writing Prospectus, to the extent required by Rule 433 under the Securities Act) and in accordance with Section 4(a) hereof; and all requests by the Commission for additional information shall have been complied with to the reasonable satisfaction of the Underwriters.

(b) The representations and warranties of the Issuer and the Guarantor contained herein shall be true and correct on the date hereof and on and as of the Closing Date; and the statements of the Issuer, the Guarantor and their officers made in any certificates delivered pursuant to this Agreement shall be true and correct on and as of the Closing Date.

(c) Simpson Thacher & Bartlett LLP, counsel for the Underwriters, shall have furnished to the Underwriters such opinion or opinions, dated the Closing Date, with respect to such matters as the Underwriters may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters.

(d) Munger, Tolles & Olson LLP, counsel for the Issuer and the Guarantor, shall have furnished to the Underwriters their written opinion and 10b-5 statement, dated the Closing Date, in form and substance reasonably satisfactory to the Underwriters, to the effect set forth in Annex C hereto.

(i) The Trustee is a national banking corporation duly incorporated and validly existing under the laws of the United States;

(ii) The execution, delivery and performance by the Trustee of the Indenture, and the authentication and delivery by the Trustee of the certificates evidencing the Securities, have been duly authorized by all necessary corporate action on the part of Trustee; the Indenture has been duly executed and delivered by the Trustee and constitutes a valid and legally binding obligation of the

14

Trustee, enforceable against the Trustee in accordance with its terms, subject to the effects of bankruptcy, insolvency, reorganization, and other similar laws relating to or affecting creditors’ rights generally and to general equity principles; and the certificates evidencing the Securities have been duly authenticated by the Trustee; and

(h) Subsequent to the earlier of (A) the Time of Sale and (B) the execution and delivery of this Agreement, (i) no downgrading shall have occurred in the rating accorded the Issuer’s or the Guarantor’s debt securities by Standard & Poor’s Ratings Services or Moody’s Investors Service, and (ii) neither such organization shall have publicly announced that it has under surveillance or review, with negative implications, its rating of any of the Issuer’s or the Guarantor’s debt securities.

15

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters. Each of the Issuer and Guarantor, jointly and severally, 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 and Guarantor. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Issuer, the Guarantor and each of their respective directors, officers who signed the Registration Statement and each person, if any, who controls the Issuer or the Guarantor 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 first sentence of the eighth paragraph and the ninth paragraph under the caption “Underwriting (Conflicts of Interest).”

16

(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 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 and the Guarantor 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 and the Guarantor 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 and the Guarantor 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 and the Guarantor 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 and the Guarantor 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, the Guarantor or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

17

(e) Limitation on Liability. The Issuer, the Guarantor 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 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

18

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.

(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, each of the Issuer and the Guarantor, jointly and severally, 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 and the Guarantor’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 and the Guarantor 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

19

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 and the Guarantor 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 and the Guarantor as provided herein, the Issuer and the Guarantor will, jointly and severally, 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 and the Guarantor 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 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, the Guarantor and the Underwriters contained in this Agreement or made by or on behalf of the Issuer, the Guarantor 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, the Guarantor 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.
