(f) The Issuers will furnish to the Representatives, upon request, and counsel for the Underwriters, upon request, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request. The Issuers will pay the expenses of printing or other production of all documents relating to the offering.

(g) The Issuers will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of FINRA in connection with its review of the offering; provided that in no event shall the Issuers be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

(h) Each of the Issuers agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Issuers that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Issuers, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” (as defined in Rule 405) required to be filed with the Commission or retained by the Issuers under Rule 433, other than the Term Sheet. Any such free writing prospectus consented to by the Representatives or the Issuers is hereinafter referred to as a “Permitted Free Writing Prospectus.” Each of the Issuers agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(i) The Issuers will not, without the prior written consent of Credit Suisse Securities (USA) LLC, from the date of this Agreement until the Closing Date, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Issuers which mature more than one year after the Closing Date, which are substantially similar to the Securities, which are denominated in the same currency as the Securities, and are offered primarily in the same market as the Securities.

(j) The Issuers will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Issuers to facilitate the sale or resale of the Securities.

(k) The Issuers, jointly and severally, agree to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities; (v) the registration of the Securities under the Exchange Act; (vi) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification) and the preparation, printing and delivery to the Underwriters of copies of the blue sky survey and any supplement thereto; (vii) any filings required to be made with FINRA (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such filings); (viii) the fees and expenses of the Issuers’ accountants and the fees and expenses of counsel (including local and special counsel) for the Issuers; (ix) the fees and expenses of the Trustee, including the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities; (x) any fees payable in connection with the rating of the Securities; and (xi) all other costs and expenses incident to the performance by the Issuers of their obligations hereunder.

6. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Issuers, Operating Partnership and the General Partner contained herein as of the Execution Time and the Closing Date, to the accuracy of the statements of the Issuers, Operating Partnership and the General Partner made in any certificates pursuant to the provisions hereof, to the performance by the Issuers, Operating Partnership and the General Partner of its obligations hereunder and to the following additional conditions:

(a) The Final Prospectus, and any supplement thereto, will have been filed in the manner and within the time period required by Rule 424(b); the Term Sheet and any other material required to be filed by the Issuers pursuant to Rule 433(d) under the Act shall have been filed with the Commission within the applicable time periods prescribed for such filings by Rule 433; and, to the knowledge of the Issuers, no stop order suspending the effectiveness of the Registration Statement or any notice that would prevent its use shall have been issued and no proceedings for that purpose shall have been instituted or threatened.

(b) The Issuers shall have requested and caused Morgan, Lewis & Bockius LLP, counsel to the Issuers, the Operating Partnership and the General Partner, to have furnished to the Representatives their opinion, dated the Closing Date and addressed to the Representatives, in form and substance attached as Annex I hereto.

(c) The Representatives shall have received from Shearman & Sterling LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Issuers shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(d) The Issuers shall have furnished to the Representatives a certificate, signed by the President or any Vice President and the principal financial or accounting officer of Finance Corp. and the General Partner, dated the Closing Date, to the effect that:

(i) the representations and warranties of the Issuers, Operating Partnership and the General Partner in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Issuers, Operating Partnership and the General Partner have complied, in all material respects, with all the agreements and performed, in all material respects, all the conditions on its part to be performed at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice that would prevent its use has been issued and no proceedings for that purpose have been instituted or, to the Issuers’ knowledge, threatened;

(iii) On or after the date hereof, (i) there shall not have occurred any downgrading, suspension or withdrawal of, nor shall any notice have been given of any potential or intended downgrading, suspension or withdrawal of, or any review (or of any potential or intended review) for a possible change that does not indicate the direction of the possible change in, any rating of the Issuers, the General Partner or the Operating Partnership or any securities of the Issuers, the General Partner or the Operating Partnership (including, without limitation, the placing of any of the foregoing ratings on credit watch with negative or developing implications or under review with an uncertain direction) by any “nationally recognized statistical rating organization” as such term is used under Section 15E of the Exchange Act, (ii) there shall not have occurred any change, nor shall any notice have been given of any potential or intended change, in the outlook for any rating of the Issuers, the General Partner or the Operating Partnership or any securities of the Issuers, the General Partner or the Operating Partnership by any such rating organization and (iii) no such rating organization shall have given notice that it has assigned (or is considering assigning) a lower rating to the Securities than that on which the Securities were marketed.

(e) The Issuers shall have requested and caused PricewaterhouseCoopers LLP, an independent registered public accounting firm, to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives.

(f) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any supplement thereto), there shall not have been any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 6, the effect of which is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto).

(g) Since the dates as of which information is given in the Final Prospectus, other than as set forth in the Disclosure Package and the Final Prospectus (exclusive of any amendments or supplements thereto subsequent to the date of this Agreement) (i) except for changes in accumulated other comprehensive income (loss) attributable to the Operating Partnership’s and the Partnership’s derivative instruments, there shall not have occurred any material adverse change in the partners’ capital or capital stock of either of the Issuers, the Operating Partnership or the General Partner, as the case may be, nor any material increase in the long-term debt of either of the Issuers, the Operating Partnership or the General Partner, (ii) there shall not have been any material adverse change or development involving a prospective change in or affecting the financial condition, business, properties, results of operations or prospects of the Issuers and the Operating Partnership, taken as a whole, or the General Partner, and (iii) none of the Issuers, the General Partner or the Operating Partnership shall have incurred any liability or obligation, direct or contingent, the effect of which, in any such case described in this paragraph 6(g), in your judgment, is material and adverse and, in your judgment, makes it impracticable to market the Securities on the terms and in the manner contemplated in the Disclosure Package and the Final Prospectus.

(h) Prior to the Closing Date, the Issuers shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

(i) The Issuers and the Trustee shall have entered into the Supplemental Indenture and you shall have received counterparts, conformed as executed, thereof.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at the Closing Date by the Representatives. Notice of such cancellation shall be given to the Issuers in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of Shearman & Sterling LLP, counsel for the Underwriters, at 599 Lexington Avenue, New York, New York 10022, on the Closing Date.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of the Issuers, Operating Partnership and the General Partner to perform any agreement herein or comply with any provision hereof other than by reason of a default or termination by any of the Underwriters pursuant to Sections 9 or 10 hereof, the Issuers will reimburse the Underwriters severally, through the Representatives on demand, for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

It is understood that, except as otherwise provided in this Agreement, the Underwriters will pay all their own costs and expenses, including the fees of their counsel, transfer taxes on any of the Securities by the Underwriters and any advertising expenses connected with any offer they make and the transportation and other expenses incurred by the Underwriters in connection with presentations to prospective purchasers of the Securities.

8. Indemnification and Contribution. (a) The Issuers, the Operating Partnership and the General Partner, jointly and severally, agree to indemnify and hold harmless each Underwriter, the directors, officers, employees, agents and affiliates of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereof or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of any material fact contained in the Basic Prospectus, any Preliminary Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the Term Sheet, or in any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuers, the Operating Partnership and the General Partner will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Issuers, the Operating Partnership and the General Partner by or on behalf of any Underwriter through the Representatives specifically for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below. This indemnity agreement will be in addition to any liability which the Issuers, the Operating Partnership and the General Partner may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Issuers, the Operating Partnership and the General Partner, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Issuers, the Operating Partnership and the General Partner within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Issuers, the Operating Partnership and the General Partner to each Underwriter, but only with reference to written information furnished to the Issuers, the Operating Partnership and the General Partner by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: the information regarding the offering price and sales through affiliates appearing in the third full paragraph under the caption “Underwriting” and the information regarding stabilizing transactions, over-allotment transactions, syndicate covering transactions, and penalty bids appearing in the ninth full paragraph under the caption “Underwriting.” This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) based on the advice of counsel, the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and 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 parties. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld).

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Issuers, the Operating Partnership and the General Partner on the one hand and the Underwriters on the other severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Issuers, the Operating Partnership and the General Partner and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuers, the Operating Partnership, the General Partner on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case under this paragraph (d) shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuers, the Operating Partnership and the General Partner on the one hand and the Underwriters on the other severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuers, the Operating Partnership and the General Partner on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Issuers, the Operating Partnership and the General Partner shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuers, the Operating Partnership and the General Partner on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Issuers, the Operating Partnership, the General Partner and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8 or each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, agent and affiliate of an Underwriter shall have the same rights to contribution as such Underwriter and each person who controls the Issuers, the Operating Partnership and the General Partner within the meaning of either the Act or the Exchange Act, each officer of the Issuers, the Operating Partnership and the General Partner who shall have signed the Registration Statement and each director of the Issuers, the Operating Partnership and the General Partner shall have the same rights to contribution as the Issuers, the Operating Partnership and the General Partner, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. (i) If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; (ii) provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Issuers. In the event of a default by any Underwriter as set forth in clause (ii) of this Section 9, the Closing Date shall be postponed for such period, not exceeding seven days, as the Representatives and Issuers shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Issuers and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Issuers prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Issuers’ securities shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering, sale or delivery of the Securities as contemplated by the Final Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Issuers, the Operating Partnership and the General Partner or their officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Issuers or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, NY 10010 fax no.: (212)  ###-###-####; with a copy to Shearman & Sterling LLP, 599 Lexington Avenue, New York, New York 10022, Attention: Jason Lehner; or, if sent to the Issuers, will be mailed, delivered or telefaxed to (610)  ###-###-#### and confirmed to it at the office of the Partnership at 460 North Gulph Road, King of Prussia, Pennsylvania 19406, Attention: Steven A.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. No Fiduciary Duty. The Issuers, Operating Partnership and the General Partner hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Issuers, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Issuers and (c) the engagement by the Issuers, Operating Partnership and the General Partner of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Issuers, Operating Partnership and the General Partner agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Issuers on related or other matters). The Issuers, Operating Partnership and the General Partner agree that they will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Issuers, in connection with such transaction or the process leading thereto.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Issuers, the Operating Partnership and the General Partner and the Underwriters, or any of them, with respect to the subject matter hereof.

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

SCHEDULE I

AmeriGas Partners, L.P.
AmeriGas Finance Corp.
6.250% Senior Notes due 2019
Pricing Term Sheet

This Pricing Term Sheet is qualified in its entirety by reference to the Preliminary Prospectus Supplement. The information in this Pricing Term Sheet supplements the Preliminary Prospectus Supplement.

We expect that delivery of the notes will be made against payment therefor on or about August 10, 2011, which will be the tenth business day following the date of pricing of the notes (such settlement cycle being herein referred to as “T+10”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or the next six succeeding business days will be required, by virtue of the fact that the notes initially will settle T+10, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of pricing or the next six succeeding business days should consult their own advisor.

The issuers have filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus included in that registration statement and other documents the issuers have filed with the SEC for more complete information about the issuers and this offering. You may get these documents free of charge by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the issuers, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling Credit Suisse Securities (USA) LLC toll-free at ###-###-####; J.P. Morgan Securities LLC at ###-###-####; Wells Fargo Securities, LLC toll-free at ###-###-#### or Citigroup Global Markets Inc. toll-free at ###-###-####.

financial statements, schedules and other financial and accounting data, including any such data
presented in interactive data format, and assessments or reports on the effectiveness of internal
control over financial reporting, as to which such counsel need not make any comments), appeared or
appear on its face to be appropriately responsive in all material respects to the applicable
requirements of the Securities Act, and (b) each of the documents incorporated by reference in the
Registration Statement, the Preliminary Prospectus Supplement and the Prospectus (except in each
case as to the financial statements, schedules and other financial and accounting data, including
any such data presented in interactive data format, and assessments or reports on the effectiveness
of internal control over financial reporting, as to which such counsel need not make any comments),
at the time such document was filed with the Commission, appeared on its face to be appropriately
responsive in all material respects to the applicable requirements of the Exchange Act.
Furthermore, subject to the foregoing, nothing came to such counsel’s attention that caused them to
believe that (i) the Registration Statement, on the most recent effective date, pursuant to Rule
430B(f)(2) under the Securities Act, of the part of the Shelf Registration Statement relating to
the Notes for purposes of the liability of the Underwriters under Section 11 of the Securities Act,
contained an untrue statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading; (ii) the Disclosure
Package, considered as a whole at the Execution Time, contained any untrue statement of a material
fact or omitted to state a material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading; or (iii) the Prospectus, as
of its date, or as of the date hereof, contained or contains any untrue statement of a material
fact or omitted or omits to state any 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 (a) such counsel need not pass upon, nor assume any responsibility for, the accuracy,
completeness or fairness of the statements contained in the Registration Statement, the Disclosure
Package and the Prospectus (except with respect to certain legal matters, as and to the extent set
forth in paragraphs 5, 6 and 13 in their opinion, dated the date hereof delivered to you pursuant
to Section 6(b) of the Underwriting Agreement) and (b) such counsel need not express any belief
with respect to the financial statements, schedules, notes, other financial and accounting data
derived therefrom (including any such data presented in interactive data format) or the report of
management’s attestation of the effectiveness of internal control over financial reporting and the
auditor’s attestation report thereon, in each case, contained in the Registration Statement, the
Disclosure Package or the Prospectus.Annex II
