Offers, Sales and Resales of Notes.

While (i) the Issuer has and shall have no obligation to sell the Notes to the Dealer or to permit the Dealer to arrange any sale of the Notes for the account of the Issuer, and (ii) the Dealer has and shall have no obligation to purchase the Notes from the Issuer or to arrange any sale of the Notes for the account of the Issuer, the parties hereto agree that in any case where the Dealer purchases Notes from the Issuer, or arranges for the sale of Notes by the Issuer, such Notes will be purchased or sold by the Dealer in reliance on the representations, warranties, covenants and agreements of the Issuer contained herein or made pursuant hereto and on the terms and conditions and in the manner provided herein and sold by the Issuer in reliance on the representations, warranties, covenants and agreements of the Dealer contained herein or made pursuant hereto and on the terms and conditions and in the manner provided herein.

So long as this Agreement shall remain in effect, and in addition to the limitations contained in Section 1.7 hereof, the Issuer shall not, without the consent of the Dealer, offer, solicit or accept offers to purchase, or sell, any Notes except (a) in transactions with one or more dealers which may from time to time after the date hereof become dealers with respect to the Notes by executing with the Issuer one or more agreements which contain provisions substantially identical to those contained in Section 1 of this Agreement, of which the Issuer hereby undertakes to provide the Dealer prompt notice, or (b) in transactions with the other dealers listed on the Addendum hereto, which are executing agreements with the Issuer which contain provisions substantially identical to Section 1 of this Agreement contemporaneously herewith or have executed agreements with the Issuer prior to the date hereof which contain such provisions (in the case of clauses (a) and (b), each an “Other Dealer” and collectively, the “Other Dealers”). In no event shall the Issuer offer, solicit or accept offers to purchase, or sell, any Notes directly on its own behalf in transactions with persons other than Other Dealers as specifically permitted in this Section 1.2.

The Notes shall have a minimum Face Amount of $250,000 or integral multiples of $1,000 in excess thereof, will bear such interest rates, if interest bearing, or will be sold at such discount from their Face Amounts, as shall be agreed upon by the Dealer and the Issuer, shall have a maturity not exceeding 397 days from the date of issuance and may have such terms as are specified in Exhibit B hereto, the Private Placement Memorandum or a pricing supplement, or as otherwise agreed upon by the applicable purchaser and the Issuer. The Notes shall not contain any provision for extension, renewal or automatic “rollover.”

The authentication and issuance of, and payment for, the Notes shall be effected in accordance with the Issuing and Paying Agent Agreement, and the Notes shall be either individual physical certificates or book-entry notes evidenced by one or more master notes (each, a “Master Note”) registered in the name of The Depository Trust Company (“DTC”) or its nominee, in the form or forms annexed to the Issuing and Paying Agent Agreement.

If the Issuer and the Dealer shall agree on the terms of the purchase of any Note by the Dealer or the sale of any Note arranged by the Dealer (including, but not limited to, agreement with respect to the date of issue, purchase price, principal amount, maturity and, where applicable, interest rate or interest rate index and margin (in the case of interest-bearing Notes) or discount thereof (in the case of Notes issued on a discount basis), and appropriate compensation for the Dealer’s services hereunder) pursuant to this Agreement, the Issuer shall cause such Note to be issued and delivered in accordance with the terms of the Issuing and Paying Agent Agreement and payment for such Note shall be made by the purchaser thereof, either directly or through the Dealer, to the Issuing and Paying Agent, for the account of the Issuer. Except as otherwise agreed, in the event that the Dealer is acting as an agent and a purchaser shall either fail to accept delivery of or make payment for a Note on the date fixed for settlement, the Dealer shall promptly notify the Issuer, and if the Dealer has theretofore paid the Issuer for the Note, the Issuer will promptly return such funds to the Dealer against its return of the Note to the Issuer, in the case of a certificated Note, and upon notice of such failure in the case of a book-entry Note. If such failure occurred for any reason other than default by the Dealer, the Issuer shall reimburse the Dealer on an equitable basis for the Dealer’s loss of the use of such funds for the period such funds were credited to the Issuer’s account.

The Dealer and the Issuer hereby establish and agree to observe the following procedures in connection with offers, sales and subsequent resales or other transfers of the Notes:

Offers and sales of the Notes by or through the Dealer shall be made only to: (i) investors reasonably believed by the Dealer to be Qualified Institutional Buyers or Institutional Accredited Investors and (ii) non-bank fiduciaries or agents that will be purchasing Notes for one or more accounts, each of which is reasonably believed by the Dealer to be an Institutional Accredited Investor.

Resales and other transfers of the Notes by the holders thereof shall be made only in accordance with the restrictions in the legend described in clause (e) of this Section 1.6 below.

No general solicitation or general advertising within the meaning of Rule 502 under the Securities Act shall be used in connection with the offering of the Notes. Without limiting the generality of the foregoing, without the prior written approval of the Dealer, the Issuer shall not issue any press release, make any other statement to any member of the press making reference to the Notes, the offer or sale of the Notes or this Agreement or place or publish any “tombstone” or other advertisement relating to the Notes or the offer or sale of the Notes. Notwithstanding the foregoing, the Issuer shall be permitted to make such filings with the SEC that the Issuer reasonably determines are required to comply with Section 13 or 15(d) of the Exchange Act to the extent such filings do not adversely affect the entitlement of the Notes to the exemptions provided by the Securities Act contemplated hereunder and are in compliance with Rule 135c under the Securities Act (a copy of which shall have been

No sale of Notes to any one purchaser shall be for less than $250,000 Face Amount, and no Note shall be issued in a smaller Face Amount. If the purchaser is a non-bank fiduciary or agent acting on behalf of others, each Person for whom such purchaser is acting must purchase at least $250,000 Face Amount of Notes.

Offers and sales of the Notes shall be subject to the restrictions described in the legend appearing in Exhibit A hereto. A legend substantially to the effect of such Exhibit A shall appear as part of the Private Placement Memorandum used in connection with offers and sales of Notes hereunder, as well as on each individual certificate representing a Note and each Master Note representing book-entry Notes offered and sold pursuant to this Agreement.

Prior to or concurrent with any offer and sale of Notes, the Dealer shall furnish or make available or shall have furnished or made available to each purchaser of Notes for which it has acted as the Dealer a copy of the then-current Private Placement Memorandum unless such purchaser has previously been furnished a copy of the Private Placement Memorandum as then in effect. The Private Placement Memorandum shall expressly state that any person to whom Notes are offered shall have an opportunity to ask questions of, and receive information from, the Issuer and the Dealer and shall provide the names, addresses and telephone numbers of the persons from whom information regarding the Issuer may be obtained.

The Issuer agrees, for the benefit of the Dealer and each of the holders and prospective purchasers from time to time of the Notes that, if at any time the Issuer shall not be subject to Section 13 or 15(d) of the Exchange Act, the Issuer will furnish, upon request and at its expense, to the Dealer and to holders and prospective purchasers of Notes information required by Rule 144A(d)(4)(i) in compliance with Rule 144A(d).

In the event that the Issuer becomes aware that any Note offered or to be offered by the Dealer would be ineligible for resale under Rule 144A, the Issuer shall promptly notify the Dealer (by telephone, confirmed in writing (which writing may be by email)) of such fact and shall promptly prepare and deliver to the Dealer an amendment or supplement to the Private Placement Memorandum describing the Notes that are ineligible, the reason for such ineligibility and any other relevant information relating thereto.

The Issuer represents that it is not currently issuing commercial paper in the United States market in reliance upon the exemption provided by Section 3(a)(3) of the Securities Act. The Issuer agrees that, if it shall issue commercial paper after the date hereof in reliance upon such exemption (a) the proceeds from the sale of the Notes will be segregated from the proceeds of the sale of any such commercial paper by

The Issuer hereby represents and warrants to the Dealer, in connection with offers, sales and resales of Notes, as follows:

The Issuer hereby confirms to the Dealer that (except as permitted by Section 1.6(i)) within the preceding six months neither the Issuer nor any person other than the Dealer or the Other Dealers acting on behalf of the Issuer has offered or sold any Notes, or any substantially similar security of the Issuer (including, without limitation, medium-term notes issued by the Issuer), to, or solicited offers to buy any such security from, any person other than the Dealer or the Other Dealers. The Issuer also agrees that (except as permitted by Section 1.6(i)), as long as the Notes are being offered for sale by the Dealer and the Other Dealers as contemplated hereby and until at least six months after the offer of Notes hereunder has been terminated, neither the Issuer nor any person other than the Dealer or the Other Dealers (except as contemplated by Section 1.2 hereof) will offer the Notes or any substantially similar security of the Issuer for sale to, or solicit offers to buy any such security from, any person other than the Dealer or the Other Dealers, it being understood that such agreement is made with a view to bringing the offer and sale of the Notes within the exemption provided by Section 4(a)(2) of the Securities Act and shall survive any termination of this Agreement. The Issuer hereby (i) represents and warrants that it has not taken or omitted to take, and (ii) covenants that it will not take, or omit to take, in each case, any action, which action (or the absence thereof, in the case of an omission) would cause the offering and sale of Notes hereunder to be integrated with any other offering of securities, whether such offering is made by the Issuer or some other party or parties on behalf of the Issuer.

The Issuer represents and agrees that the proceeds of the sale of the Notes are not currently contemplated to be used for the purpose of buying, carrying or trading securities within the meaning of Regulation T and the interpretations thereunder by the Board of Governors of the Federal Reserve System. In the event that the Issuer determines to use such proceeds for the purpose of buying, carrying or trading securities, whether in connection with an acquisition of another company or otherwise, the Issuer shall give the Dealer at least three business days’ prior written notice to that effect (but shall not be required to identify or disclose such securities). Thereafter, in the event that the Dealer purchases Notes as principal and does not resell such Notes on the day of such purchase, to the extent necessary to comply with Regulation T and the interpretations thereunder, the Dealer will sell such Notes either (i) only to offerees it reasonably believes to be Qualified Institutional Buyers or to Qualified Institutional Buyers it reasonably believes are acting for other Qualified Institutional Buyers, in each case in accordance with Rule 144A, or (ii) in a manner which would not cause a violation of Regulation T and the interpretations thereunder.

The Issuer shall not issue Notes, or request the Dealer to offer and sell Notes, to the extent that after giving effect to such issuance and the application of the proceeds thereof, the aggregate Face Amount of outstanding Notes under the Program would exceed the Maximum Amount. The Issuer may from time to time increase the Maximum Amount by:

giving at least ten (10) days’ notice by letter substantially in the form attached hereto as Exhibit C (the “Notification Letter for an Increase in the Maximum Amount”) to the Dealer and the Issuing and Paying Agent; and

delivery of (i) a certificate from a duly authorized officer of the Issuer confirming that no changes have been made to the organizational documents of the Issuer since the date a certified copy thereof was most recently delivered to the Dealer or, if there has been any such change, a certified copy of the related organizational documents currently in force; (ii) a certified copy of the resolutions of the Issuer approving such an increase in the Maximum Amount; (iii) an updated or supplemental Private Placement Memorandum reflecting the increase in the Maximum Amount of the Program; (iv) customary opinions of counsel to the Issuer in form and substance reasonably satisfactory to the Dealer as to (A) the due authorization, validity and enforceability of the Notes issued pursuant to the Issuing and Paying Agent Agreement, and (B) such other matters as the Dealer may reasonably request, in each case after giving effect to the increase in the Maximum Amount; (v) evidence from each nationally recognized statistical rating organization providing a rating of the Notes either (A) that such rating has been confirmed after giving effect to the increase in the Maximum Amount or (B) setting forth any change in the rating of the Notes after giving effect to the increase in the Maximum Amount; and (vi) such other certificates, opinions, letters and documents as the Dealer shall have reasonably requested.

Representations and Warranties of the Issuer.

The Issuer is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all the requisite corporate power and authority to execute, deliver and perform its obligations under the Notes, this Agreement and the Issuing and Paying Agent Agreement.

This Agreement and the Issuing and Paying Agent Agreement have been duly authorized, executed and delivered by the Issuer and constitute legal, valid and binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and limitations on rights to indemnity and contribution imposed by applicable law.

The Notes have been duly authorized, and when issued and delivered as provided in the Issuing and Paying Agent Agreement, the Notes will be duly and validly issued and will constitute legal, valid and binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

Assuming compliance by the Dealer with the procedures applicable to it set forth in this Agreement, the offer and sale of the Notes in the manner contemplated hereby do not require registration of the Notes under the Securities Act, and no indenture in respect of the Notes is required to be qualified under the Trust Indenture Act of 1939, as amended.

The Notes will rank at least pari passu in right of payment with all other unsecured and unsubordinated indebtedness of the Issuer.

Assuming compliance by the Dealer with the procedures applicable to it set forth in this Agreement, no consent or action of, or filing or registration with, any governmental or public regulatory body or authority, including the SEC, is required to authorize, or is otherwise required in connection with the execution, delivery or performance of, this Agreement, the Notes or the Issuing and Paying Agent Agreement by the Issuer, except such as have been obtained or made and are in full force and effect or as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Notes or reporting requirements under the Exchange Act.

Neither the execution and delivery of this Agreement and the Issuing and Paying Agent Agreement by the Issuer, nor the issuance of the Notes in accordance with the Issuing and Paying Agent Agreement, nor the fulfillment of or compliance with the terms and provisions hereof or thereof by the Issuer, will (i) result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever upon any of the properties or assets of the Issuer, or (ii) violate or result in a breach or a default under (a) the Issuer’s charter documents or by-laws, (b) any contract or instrument to which the Issuer is a party or by which it or its property is bound, or (c) any law or regulation, or any order, writ, injunction or decree of any court or government instrumentality, to which the Issuer is subject or by which it or its property is bound, which mortgage, lien, charge or encumbrance with respect to clause (i) or violation, breach or default with respect to clauses (b) or (c) of clause (ii) would reasonably be expected to have a material adverse effect on the financial condition or operations of the Issuer and its Subsidiaries taken as a whole or the ability of the Issuer to perform its obligations under this Agreement, the Notes or the Issuing and Paying Agent Agreement.

There is no litigation or governmental proceeding pending, or to the knowledge of the Issuer threatened, against or affecting the Issuer or any of its Subsidiaries (other than that which is disclosed in the Company Information) that would reasonably be expected to result in a material adverse change in the financial condition or operations of the Issuer and its Subsidiaries taken as a whole or the ability of the Issuer to perform its obligations under this Agreement, the Notes or the Issuing and Paying Agent Agreement.

The Issuer is not required to be registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Neither the Private Placement Memorandum (excluding Dealer Information) nor the Company Information contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

Policies and procedures have been implemented and maintained by or on the Issuer’s behalf that are designed to achieve compliance by it and its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, giving due regard to the nature of such Person’s business and activities. The Issuer and its Subsidiaries and, to the knowledge of the Issuer, their respective directors, officers and employees, are in compliance with Anti-Corruption Laws and applicable Sanctions. Neither the Issuer nor any of its Subsidiaries nor, to the Issuer’s knowledge any of their respective directors, officers, employees or agents, is a person that

The Issuer shall not, directly or indirectly, use the proceeds of any Notes, or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other Person, in each case, (i) to fund any activities or business of or with any person, or in any country or territory, that, at the time of such funding, is, or whose government is, the subject of Sanctions, or (ii) in any other manner that would result in a violation of Sanctions by any Person.

The operations of the Issuer and its Subsidiaries are conducted in compliance in all material respects with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any applicable related or similar rules, regulations or guidelines issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or regulatory body or any arbitrator involving the Issuer or any of its Subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the Issuer, threatened.

Each (a) issuance of Notes by the Issuer hereunder and (b) amendment or supplement of the Private Placement Memorandum shall be deemed a representation and warranty by the Issuer to the Dealer, as of the date thereof, that, both before and after giving effect to such issuance and after giving effect to such amendment or supplement, (i) the representations and warranties given by the Issuer set forth in this Section 2 remain true and correct on and as of such date as if made on and as of such date, (ii) in the case of an issuance of Notes, the Notes being issued on such date have been duly and validly issued and constitute legal, valid and binding obligations of the Issuer, enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law), (iii) in the case of an issuance of Notes, since the date of the most recent Private Placement Memorandum (as most recently amended or supplemented including, without limitation, by incorporation of Company Information therein), there has been no material adverse change in the financial condition or operations of the Issuer and its Subsidiaries taken as a whole that would reasonably be expected to affect the ability of the Issuer to perform its obligations under this Agreement, the Notes or the Issuing and Paying Agent Agreement which has not been disclosed to the Dealer in writing or in the Company Information and (iv) the Issuer is not in default of any of its obligations under (x) the Notes or (y) in any material respect, this Agreement or the Issuing and Paying Agent Agreement.

The Issuer will not be in default of any of its payment obligations hereunder, under the Notes or under the Issuing and Paying Agent Agreement, or material nonpayment obligations under such agreements, at any time that any of the Notes are outstanding.

(a) The Issuer further agrees to notify the Dealer promptly upon the occurrence of any event relating to or affecting the Issuer that would cause the Company Information then in existence (limiting the Company Information described in clause (iii) of the definition of Company Information to that used in the offer and sale of the Notes) to include an untrue statement of a material fact or to omit to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which they are made, not misleading, except to the extent that the Issuer, by furnishing such notice, would violate any law, regulation or stock exchange rule applicable to it. The Issuer agrees to not request any offer or sale of Notes after the occurrence of any such event or delivery of any such notice while such event is continuing, unless the Issuer supplements or amends the Company Information so that the Company Information, as amended or supplemented, shall not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading. The Dealer agrees to promptly suspend offers and sales of the Notes upon receipt of such notice.

Indemnification and Contribution.

The Issuer will indemnify and hold harmless the Dealer, each individual, corporation, partnership, trust, association or other entity controlling the Dealer, any affiliate of the Dealer or any such controlling entity and their respective directors, officers, employees, partners, incorporators, shareholders, servants, trustees and agents (hereinafter the “Indemnitees”) against any and all liabilities, penalties, suits, causes of action, losses, damages, claims, costs and expenses (including, without limitation, reasonable fees and disbursements of a single external counsel and a single external local counsel in each applicable jurisdiction) or judgments of whatever kind or nature (each a “Claim”), imposed upon, incurred by or asserted against the Indemnitees arising out of or based upon (i) any allegation that the Private Placement Memorandum, the Company Information or any information provided by the Issuer to the Dealer for dissemination to investors or potential investors in the Notes included (as of any relevant time) or includes an untrue statement of a material fact or omitted (as of any relevant time) or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or (ii) the breach by the Issuer of any agreement, covenant or representation made in or pursuant to this Agreement. This indemnification shall not apply to the extent that the Claim arises out of or is based upon (x) Dealer Information or (y) solely with respect to a Claim arising under clause (ii), the gross negligence or willful misconduct of the Dealer as determined by a court of competent jurisdiction in a final non-appealable judgment.

The Issuer agrees to reimburse each Indemnitee for all reasonable and documented out-of-pocket expenses (including reasonable fees and disbursements of a single external counsel and a single external local counsel in each applicable jurisdiction) as they are incurred by it in connection with investigating or defending any loss, claim, damage, liability or action in respect of which indemnification may be sought under Section 5.1 of this Agreement (whether or not it is a party to any such proceedings).

Promptly after receipt by an Indemnitee of notice of the existence of a Claim, such Indemnitee will, if a claim in respect thereof is to be made against the Issuer, notify the Issuer in writing of the existence thereof; provided that (i) the omission so to notify the Issuer will not relieve the Issuer from any liability which it may have hereunder unless and except to the extent it did not otherwise learn of such Claim and such failure results in the forfeiture by the Issuer of substantial rights and defenses, and (ii) the omission so to notify the Issuer will not relieve it from liability which it may have to an Indemnitee otherwise than on account of this Agreement. In case any such Claim is made against any Indemnitee and it notifies the Issuer of the existence thereof, or the Issuer otherwise learns of such Claim, the Issuer will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the Indemnitee, to assume and direct the defense thereof, with counsel reasonably satisfactory to such Indemnitee; provided that if the defendants in any such Claim include both the Indemnitee and the Issuer, and the Indemnitee shall have reasonably concluded that there may be legal defenses available to it which are different

In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 5 is held to be unavailable or insufficient to hold harmless the Indemnitees, although applicable in accordance with and subject to the terms of this Section 5, the Issuer shall contribute to the aggregate costs incurred by the Dealer and its related Indemnitees in connection with any Claim in the proportion of the respective economic interests of the Issuer and the Dealer and its related Indemnitees; provided, however, that such contribution by the Issuer shall be in an amount such that the aggregate costs incurred by the Dealer and its related Indemnitees do not exceed the aggregate of the commissions and fees actually received by the Dealer hereunder with respect to the issue or issues of Notes to which such Claim relates. The respective economic interests shall be calculated by reference to the aggregate proceeds to the Issuer of the Notes issued hereunder and the aggregate commissions and fees earned by the Dealer hereunder.

General

Unless otherwise expressly provided herein, all notices under this Agreement to parties hereto shall be in writing and shall be effective when received at the address of the respective party set forth in the Addendum to this Agreement.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflict of laws provisions that would apply the law of a different jurisdiction.

(a) The Issuer agrees that any suit, action or proceeding brought by the Issuer against the Dealer in connection with or arising out of this Agreement or the Notes or the offer and sale of the Notes shall be brought solely in the United States federal courts located in the Borough of Manhattan or the courts of the State of New York located in the Borough of Manhattan. EACH OF THE DEALER AND THE ISSUER WAIVES ITS RIGHT TO TRIAL BY JURY IN ANY SUIT, ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

This Agreement may be terminated, at any time, by the Issuer, upon one business day’s prior notice to such effect to the Dealer, or by the Dealer upon one business day’s prior notice to such effect to the Issuer. Any such termination, however, shall not affect the obligations of the Issuer and the Dealer under Sections 3.7, 5 and 7.3 hereof or the respective representations, warranties, agreements, covenants, rights or responsibilities of the parties made or arising prior to the termination of this Agreement.

This Agreement is not assignable by either party hereto without the written consent of the other party; provided, however, that the Dealer may assign its rights and obligations under this Agreement to any affiliate of the Dealer that is a wholly-owned direct or indirect Subsidiary of the ultimate parent entity of the Dealer and which acts as a dealer of commercial paper in the United States.

This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Each party to this Agreement agrees that the other party may execute its counterpart of this Agreement by (i) an “electronic signature”, whether digital or encrypted, to the maximum extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the Electronic Signatures and Records Act of New York, or any similar state laws based on the Uniform Electronic Transactions Act or (ii) electronic transmission (including electronic mail in portable document format (pdf.) form), or other electronic means that reproduces an image of a manually-signed counterpart or (iii) a digital signature transmitted through DocuSign, Adobe Sign or any other secure portal for digitized signature of documents that complies with the U.S. federal ESIGN Act of 2000. Any such counterpart shall be effective to the same extent as delivery of a manually executed counterpart of this Agreement and treated as an original manually executed counterpart for all purposes of this Agreement.

Except as provided in Section 5 with respect to non-party Indemnitees, this Agreement is for the exclusive benefit of the parties hereto, and their respective permitted successors and assigns hereunder, and shall not be deemed to give any legal or equitable right, remedy or claim to any other Person whatsoever; provided, however, that Section 7.3(b) is hereby specifically and expressly acknowledged to also be for the benefit of the holders from time to time of the Notes, as third-party beneficiaries.

The Issuer acknowledges and agrees that (i) purchases and sales, or placements, of the Notes pursuant to this Agreement, including the determination of any prices for the Notes and Dealer compensation, are arm’s-length commercial transactions between the Issuer and the Dealer, (ii) in connection therewith and with the process leading to such transactions, the Dealer is acting solely as a principal and not the agent (except to the extent explicitly set forth herein) or fiduciary of the Issuer or any of its affiliates, (iii) the Dealer has not assumed an advisory or fiduciary responsibility in favor of the Issuer or any of its affiliates

(i) The parties hereto agree that the Issuer may, in accordance with the terms of this Section 7.9, from time to time replace the party which is then acting as Issuing and Paying Agent (the “Current Issuing and Paying Agent”) with another party (such other party, the “Replacement Issuing and Paying Agent”), and enter into an agreement with the Replacement Issuing and Paying Agent covering the provision of issuing and paying agency functions in respect of the Notes by the Replacement Issuing and Paying Agent (the “Replacement Issuing and Paying Agent Agreement”) (any such replacement, a “Replacement”).

Notwithstanding anything to the contrary in this Agreement, the parties hereto agree that:

Final Maturity. The Stated Maturity Date for any Note will be the date so specified in the Supplement, which shall be no later than 397 days from the date of issuance. On its Stated Maturity Date, or any date prior to the Stated Maturity Date on which the particular Note becomes due and payable by the declaration of acceleration, each such date being referred to as a Maturity Date, the principal amount of such Note, together with accrued and unpaid interest thereon, will be immediately due and payable.

Events of Default. The occurrence of any of the following shall constitute an “Event of Default” with respect to a Note: (i) default in any payment of principal of or interest on such Note (including on a redemption thereof); (ii) the Issuer makes any compromise arrangement with its creditors generally including the entering into any form of moratorium with its creditors generally; (iii) a court having jurisdiction shall enter a decree or order for relief in respect of the Issuer in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or there shall be appointed a receiver, administrator, liquidator, custodian, trustee or sequestrator (or similar officer) with respect to the whole or substantially the whole of the assets of the Issuer and any such decree, order or appointment is not removed, discharged or withdrawn within 60 days thereafter; or (iv) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, administrator, liquidator, assignee, custodian, trustee or sequestrator (or similar official), with respect to the whole or substantially the whole of the assets of the Issuer or make any general assignment for the benefit of creditors. Upon the occurrence of an Event of Default, the principal of such Note (together with interest accrued and unpaid thereon) shall become, without any notice or demand, immediately due and payable.¹

Obligation Absolute. No provision of the Issuing and Paying Agent Agreement under which the Notes are issued shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on each Note at the times, place and rate, and in the coin or currency, herein prescribed.

Supplement. Any term contained in the Supplement shall supersede any conflicting term contained herein.

Unlike single payment notes, where a default arises only at the stated maturity, interest-bearing notes with multiple payment dates should contain a default provision permitting acceleration of the maturity if the Issuer defaults on an interest payment.
