The Securities will be issued pursuant to (1) an Indenture dated February 14, 2012 (the “Base Indenture”) between the Company and U.S. Bank National Association, as trustee (the “Trustee”), and (2) the Fourth Supplemental Indenture to be dated as of the Closing Date (the “Supplemental Indenture”, and together with the Base Indenture, the “Indenture”) between the Company and the Trustee.

The term

The term “Prospectus” shall mean the prospectus supplement relating to the Securities that is first filed pursuant to Rule 424(b) after the execution and delivery of this Agreement, together with the Base Prospectus included in the Registration Statement. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

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

(b)        Delivery of Copies. The Company will deliver, without charge, (i) to the Representatives, three photocopies of the manually signed copy of the Registration Statement as filed and each amendment thereto, in each case including all exhibits and consents filed therewith; and (ii) to each Underwriter (A) a conformed copy of the Registration Statement as originally filed and each amendment thereto (without exhibits) and (B) during the Prospectus Delivery Period (as defined below), as many copies of the Preliminary Prospectus and the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein and each Issuer Free Writing Prospectus) as the Representatives may reasonably request. As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Securities as in the opinion of counsel for the Underwriters a prospectus relating to the Securities is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Securities by any Underwriter or dealer.

(c)        Amendments or Supplements, Issuer Free Writing Prospectuses. Before preparing, using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, and before filing any amendment or supplement to the Registration Statement or the Prospectus, whether before or after the time that the Registration Statement becomes effective, the Company will furnish to the Representatives and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not prepare, use, authorize, approve, refer to or file any such Issuer Free

12

Writing Prospectus or file any such proposed amendment or supplement to which the Representatives reasonably object.

(d)        Notice to the Representatives. The Company will advise the Representatives promptly, and confirm such advice in writing, (i) when the Registration Statement has become effective; (ii) when any amendment to the Registration Statement has been filed or becomes effective; (iii) when any supplement to the Prospectus or any Issuer Free Writing Prospectus or any amendment to the Prospectus has been filed; (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (v) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus, any of the Pricing Disclosure Package or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (vi) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus, the Pricing Disclosure Package or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Pricing Disclosure Package or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vii) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act; and (viii) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus, any of the Pricing Disclosure Package or the Prospectus or suspending any such qualification of the Securities and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(e)        Ongoing Compliance. (1) If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law and (2) if at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which the Pricing Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Pricing Disclosure Package is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Pricing Disclosure Package to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate such amendments or supplements to the Pricing Disclosure Package as may be necessary so that the statements in the Pricing Disclosure Package as so amended or supplemented will not, in the light of the circumstances existing when the Pricing Disclosure Package is delivered to a purchaser, be misleading or so that the Pricing Disclosure Package will comply with law.

13

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

(g)        Earning Statement. The Company will make generally available to its security holders and the Representatives as soon as practicable an earning statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the “effective date” (as defined in Rule 158) of the Registration Statement.

(h)        Clear Market. During the period from the date hereof through and including the Closing Date, the Company will not, without the prior written consent of the Representatives, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Company and having a tenor of more than one year.

(i)        Use of Proceeds. The Company will apply the net proceeds from the sale of the Securities as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the heading “Use of Proceeds.”

(j)        No Stabilization. The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

(k)        Reports. So long as the Securities are outstanding, the Company will furnish to the Representatives, as soon as they are available, copies of all reports or other communications (financial or other) furnished to holders of the Securities, and copies of any reports and financial statements furnished to or filed with the Commission or any national securities exchange or automatic quotation system; provided the Company will be deemed to have furnished such reports and financial statements to the Representatives to the extent they are filed on the Commission’s Electronic Data Gathering, Analysis, and Retrieval system.

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

Subsequent to the earlier of (A) the Applicable Time and (B) the execution and delivery of this Agreement, if there are any debt securities or preferred stock of, or guaranteed by, the Company or any of its subsidiaries that are rated by a “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act, (i) no downgrading shall have occurred in the rating accorded any such debt securities or preferred stock and (ii) no such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its rating of any such debt securities or preferred stock (other than an announcement with positive implications of a possible upgrading).

(d)        No Material Adverse Change. No event or condition of a type described in Section 3(g) hereof shall have occurred or shall exist, which event or condition is not described in the Pricing Disclosure Package (excluding any amendment or supplement thereto) and the Prospectus (excluding any amendment or supplement thereto) and the effect of which in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

The Representatives shall have received on and as of the Closing Date a certificate of the chief financial officer or chief accounting officer of the Company and one additional senior executive officer of the Company who is satisfactory to the Representatives (i) confirming that such officers have carefully reviewed the Registration Statement, the Pricing Disclosure Package and the Prospectus and, to the knowledge of such officers, the representations set forth in Sections 3(b) and 3(d) hereof are true and correct, (ii) confirming that the other representations and warranties of the Company in this Agreement are true and correct and that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date and (iii) to the effect set forth in paragraphs (a), (c) and (d) above.

6.        Indemnification and Contribution.

(a)        Indemnification of the Underwriters. The Company 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, 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 Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), 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 relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use 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.

(b)        Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in

16

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 relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession figure appearing in the fifth paragraph under the caption “Underwriting” and the information contained in the ninth and tenth paragraphs under the caption “Underwriting.”

(c)        Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of

17

any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)        Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person 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 Company, 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 Company, 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 Company, 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 Company 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 Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company, 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 Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)        Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person 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 Person in connection with any such action or claim. Notwithstanding the provisions of this Section 6, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities 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 6 are several in proportion to their respective purchase obligations hereunder and not joint.

(f)        Non-Exclusive Remedies. The remedies provided for in this Section 6 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.

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

18

8.        Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq Stock Market, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

9.        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 on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 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 Company 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 Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the 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 9, 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 Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date does not exceed one-eleventh of the aggregate number of Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Securities that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Securities that such Underwriter agreed to purchase on such date) 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 Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date exceeds one-eleventh of the aggregate amount of Securities to be purchased on such date, or if the Company 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 9 shall be without liability on the part of the Company, except that the

19

Company will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 6 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 Company or any non-defaulting Underwriter for damages caused by its default.

10.        Payment of Expenses.

(a)        Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the reasonable fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification of the Securities under the state or foreign securities or blue sky laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable fees and expenses of counsel for the Underwriters); (vi) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA; (vii) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; (viii) the costs incident to the rating of the Securities by any rating agencies; and (ix) the costs incident to the engagement of the Trustee and its counsel.

(b)        If (i) this Agreement is terminated pursuant to Section 8, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

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 the officers and directors and any controlling persons referred to in Section 6 hereof. 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 Company and the Underwriters contained in this Agreement or made by or on behalf of the Company 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 Company or the Underwriters.

* Note: It is expected that delivery of the notes will be made to investors on or about February 23, 2021, which will be the tenth business day following the date hereof (such settlement cycle being referred to as ‘‘T+10’’). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise.

Purchasers of the notes who wish to trade the notes on the date of pricing or on the next seven succeeding business days should consult their own advisors.

ARTICLE 2

GENERAL TERMS AND CONDITIONS OF THE NOTES

Section 2.01. Designation and Principal Amount. The Notes are hereby authorized and are designated the 2.800% Senior Notes due 2031, unlimited in aggregate principal amount. The Notes issued on the date hereof pursuant to the terms of this Indenture will be in an aggregate principal amount of $300,000,000, which amount shall be set forth in the written order of the Company for the authentication and delivery of the Notes pursuant to Section 3.03 of the Base Indenture. In addition, the Company may issue, from time to time in accordance with the provisions of this Indenture, additional Notes ranking equally and ratably with the Notes issued hereunder in all respects (or in all respects except for the payment of interest following the Issue Date of such further Notes), so that such further Notes shall be consolidated and form a single series with the Notes and shall be governed by the terms of this Indenture.

Section 2.02. Maturity. The principal amount of the Notes will be payable on March 1, 2031.

Section 2.03. Form and Payment. The Notes will be issued as global notes, in fully registered book-entry form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Principal, premium, if any, and/or interest, if any, on the global notes representing the Notes will be made to The Depository Trust Company (the “Depositary”).

The global notes representing the Notes will be deposited with, or on behalf of, the Depositary and will be registered in the name of the Depositary or a nominee of the Depositary. No global note may be transferred except as a whole by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or such nominee to a successor of the Depositary or a nominee of such successor.

So long as the Depositary or its nominee is the registered owner of a global note, the Depositary or its nominee, as the case may be, will be the sole Holder of the Notes represented thereby for all purposes under the Indenture. Except as otherwise provided herein, each actual purchaser of each Note represented by a global note (“Beneficial Owner”) will not be entitled to receive physical delivery of certificated Notes and will not be considered the holders thereof for any purpose under the Indenture, and no global note representing the Notes shall be exchangeable or transferable. Accordingly, each Beneficial Owner

9

must rely on the procedures of the Depositary and, if such Beneficial Owner is not a participant, on the procedures of the participant through which such Beneficial Owner owns its interest in order to exercise any rights of a Holder under such global note or the Indenture.

The global notes representing the Notes will be exchangeable for certificated Notes of like tenor and terms and of differing authorized denominations aggregating a like principal amount, only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the global notes, (ii) the Depositary ceases to be a clearing agency registered under applicable law and a successor to the Depositary is not appointed by the Company within 90 days, (iii) the Company in its sole discretion determines that the global notes shall be exchangeable for certificated Notes and notifies the Trustee of such determination or (iv) there shall have occurred and be continuing an Event of Default under the Indenture with respect to the Notes. Upon any such exchange, the certificated Notes shall be registered in the names of the Beneficial Owners of the global notes representing the Notes, which names shall be provided by the Depositary’s relevant participants (as identified by the Depositary) to the Trustee. In such event the Company will execute, and subject to Section 3.03 of the Base Indenture, the Trustee, upon receipt of an Officer’s Certificate evidencing such determination by the Company, will authenticate and deliver the Notes in definitive registered form without coupons, in authorized denominations, and in an aggregate principal amount equal to the principal amount of the global notes in exchange for such global notes. Upon the exchange of the global notes for such Notes in definitive registered form without coupons, in authorized denominations, the global notes shall be cancelled by the Trustee. Such Notes in definitive registered form issued in exchange for the global notes shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Notes to the Depositary for delivery to the Persons in whose names such Notes are so registered.

Section 2.04. Interest. The Notes shall bear interest at a rate equal to 2.800% per annum. Interest on the Notes shall accrue from February 23, 2021, or from the most recent interest payment date to which interest has been paid or duly provided upon for the Notes, as the case may be. Interest on the Notes shall be payable semi-annually in arrears on March 1 and September 1, commencing September 1, 2021 (each an “Interest Payment Date”), to the persons in whose names the Notes are registered at the close of business on February 15 and August 15 (even if such date is not a Business Day), as the case may be, preceding such Interest Payment Date.

10

ARTICLE 3

REDEMPTION OF THE NOTES

Section 3.01. Optional Redemption. The Notes will be redeemable, in whole or in part, at the option of the Company at any time, upon not less than 10 nor more than 60 days’ notice.

If the Redemption Date occurs before the date that is three months prior to the Stated Maturity (the “Par Call Date”), the Company will pay the Holders of the Notes being redeemed a Redemption Price equal to the greater of (i) 100% of the principal amount of their redeemed Notes, or (ii) as determined by the Independent Investment Banker, the sum of the present values of the remaining principal amount and scheduled payments of interest on the Notes to be redeemed from the Redemption Date to the Par Call Date (not including the portion of any such payments of interest accrued as of the Redemption Date), discounted to the Redemption Date in accordance with customary market practice on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus, in each case, accrued and unpaid interest thereon to the Redemption Date.

If the Redemption Date occurs on or after the Par Call Date, the Company will pay the Holders of the Notes being redeemed a Redemption Price equal to 100% of the principal amount of their redeemed Notes, plus accrued and unpaid interest thereon to the Redemption Date.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes, or portions thereof called for redemption. If fewer than all of the Notes are to be redeemed, the Trustee will select the Notes to be redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption Notes and portions of the Notes in principal amounts of $2,000 and any integral multiple of $1,000 in excess thereof.

Section 3.02. No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund.

Section 3.03. Change of Control Offer.

(a)    If a Change of Control Triggering Event occurs, each Holder of the Notes will have the right to require the Company to purchase all or a portion (equal to $2,000 principal amount and any integral multiples of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer described below (a “Change of Control Offer”) at a purchase price equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest, if any, to the date of repurchase (the “Change of Control Payment”), subject to the rights of

11

Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date.

(b)    The Company will be required to send a notice to each Holder of the Notes by first-class mail, with a copy to the Trustee, within 30 days following the date upon which any Change of Control Triggering Event occurred, or at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control. The notice will govern the terms of the Change of Control Offer and will describe, among other things, the transaction that constitutes or may constitute the Change of Control Triggering Event and the purchase date. The purchase date will be at least 30 days but no more than 60 days from the date such notice is mailed, other than as may be required by law (a “Change of Control Payment Date”). If the notice is mailed prior to the date of consummation of the Change of Control, the notice will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

(c)    On the Change of Control Payment Date, the Company will, to the extent lawful:

(i)    accept for payment all properly tendered Notes or portions of Notes not validly withdrawn;

(ii)    deposit with the Paying Agent the required payment for all properly tendered Notes or portions of Notes not validly withdrawn; and

(iii)    deliver or cause to be delivered to the Trustee the repurchased Notes, accompanied by an Officer’s Certificate stating, among other things, the aggregate principal amount of repurchased Notes.

(d)    The Company will not be required to make a Change of Control Offer with respect to the Notes upon the occurrence of a Change of Control Triggering Event if a third party makes a Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and the third party purchases all Notes properly tendered and not withdrawn under its Change of Control Offer.

(e)    The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable, in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached the Company’s obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

(REVERSE OF NOTE)

KENNAMETAL INC.

2.800% Senior Notes due 2031

This Note is one of a duly authorized series of Securities of the Company (herein sometimes referred to as the “Securities”) specified in the Indenture (as defined below), all issued or to be issued in one or more series under and pursuant to an Indenture dated as of February 14, 2012 (the “Base Indenture”), duly executed and delivered between the Company and U.S. Bank National Association, as Trustee (the “Trustee”), as supplemented by a Fourth Supplemental Indenture, dated February 23, 2021 (the Base Indenture as so supplemented, the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. By the terms of the Indenture, the Securities are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Indenture.

The Notes are not entitled to the benefit of any sinking fund.

The Notes will be redeemable, in whole or in part, at the option of the Company at any time, upon not less than 10 nor more than 60 days’ notice. If the Redemption Date occurs before the date that is three months prior to the Stated Maturity (the “Par Call Date”), the Company will pay the Holders of the Notes being redeemed a Redemption Price equal to the greater of (i) 100% of the principal amount of their redeemed Notes, or (ii) as determined by the Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed from the Redemption Date to the Par Call Date (not including the portion of any such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date in accordance with customary market practice on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus, in each case, accrued and unpaid interest thereon to the Redemption Date. If the Redemption Date occurs on or after the Par Call Date, the Company will pay the Holders of the Notes being redeemed 100% of the principal amount of their redeemed Notes, plus accrued and unpaid interest on the redeemed thereon to the Redemption Date. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption.

If less than all of the Notes of a series are to redeemed, the Trustee will select the Notes to be redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption Notes and portions of Notes

5

in principal amounts of whole multiples of $2,000 and any integral multiple of $1,000 in excess thereof.

Upon the occurrence of a Change of Control Triggering Event (as defined in the Indenture), Holders will have the right to require the Company to repurchase the Notes on the terms and conditions set forth in the Indenture.

The Indenture contains provisions for defeasance of (a) the entire indebtedness of this Note and (b) certain restrictive covenants upon compliance by the Company with certain conditions set forth therein.

In case an Event of Default shall have occurred and be continuing, the principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes of each series affected at the time Outstanding, to execute supplemental indentures for the purpose of, among other things, adding any provisions to or changing or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying the rights of the Holders of the Notes; provided, however, that, among other things, no such supplemental indenture shall (i) reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon (subject to the Company’s right to defer such payments in the manner set forth herein), or reduce any premium payable upon the redemption thereof, without the consent of the Holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of each Note then Outstanding and affected thereby. The Indenture also contains provisions permitting, among other things, the Holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding affected thereby, on behalf of all of the Holders of all Securities of such series, to waive a Default or Event of Default with respect to such series, and its consequences, except a Default or Event of Default in the payment of the principal of or premium, if any, or interest on any of the Securities of such series. Any such consent or waiver by the registered Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and of any Note issued in exchange for or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and

6

interest on this Note at the times, place and at the rates and in the money herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, this Note is transferable by the registered Holder hereof on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Trustee in Pittsburgh, Pennsylvania duly endorsed by, or accompanied by, a written instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and for the same aggregate principal amount and series will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any Paying Agent and the Security Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Security Registrar) for the purpose of receiving payment of or on account of the principal hereof and premium, if any, and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any Paying Agent nor any Security Registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of or the interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, shareholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, and such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

The Indenture imposes certain limitations on the ability of the Company to, among other things, merge or consolidate with any other Person, sell, assign, transfer or lease all or substantially all of its properties or assets or create or incur liens on certain of its property. All such covenants and limitations are subject to a number of important qualifications and exceptions. The Company must report periodically to the Trustee on compliance with the covenants in the Indenture.

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Notes of this series or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives

7

and releases all such liability. The waiver and release are part of the consideration for the issuance of this Note.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures (“CUSIP”), the Company has caused CUSIP numbers to be printed on the Notes. No representation is made as to the correctness or accuracy of such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon.

The Notes of this series are issuable only in fully registered book-entry form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series so issued are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the Holder surrendering the same.

This Note shall be governed by and construed in accordance with the law of the State of New York.

All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Matters Excluded from Our Opinions

We express no opinion with respect to the following matters:

(a)    Indemnification and Change of Control. The enforceability of any agreement relating to (i) indemnification, contribution or exculpation from costs, expenses or other liabilities or (ii) changes in the organizational control or ownership of any party, which agreement (in the case of clause (i) or clause (ii)) is contrary to public policy or Applicable Law.

(b)    Jurisdiction, Venue, etc. The enforceability of any agreement to submit to the jurisdiction of any specific federal or state court (other than the enforceability in a court of the State of New York) of any such agreement to submit to the jurisdiction of a court of the State of New York, to waive any objection to the laying of the venue, to waive the defense of forum non conveniens in any action or proceeding referred to therein, to waive trial by jury, to effect service of process in any particular manner or to establish evidentiary standards, and any agreement of the Company regarding the choice of law governing any Subject Document (other than the enforceability in a court of the State of New York or in a federal court sitting in the State of New York and applying New York law to any such agreement) that the laws of the New York shall govern the Indenture.

(c)    Remedies. The enforceability of any provision in any Subject Document to the effect that rights or remedies are not exclusive, that every right or remedy is cumulative and may be exercised in addition to any other right or remedy, that the election of some particular remedy does not preclude recourse to one or more others or that failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy.

Qualifications and Limitations Applicable to Our Opinions

The opinions set forth above are subject to the following qualifications and limitations:

(a)    Applicable Law. Our opinions are limited to the Applicable Law, and we do not express any opinion concerning any other law.

(b)    Bankruptcy. Our opinions are subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, laws relating to preferences, fraudulent transfers and equitable subordination), reorganization, moratorium and other similar laws affecting creditors’ rights generally.

(c)    Equitable Principles. Our opinions are subject to the effect of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing. In applying such principles, a court, among other things, might limit the availability of specific equitable remedies (such as injunctive relief and the remedy of specific performance), might not allow a creditor to accelerate maturity of debt or exercise other remedies upon the occurrence of a default deemed immaterial or for non-credit reasons or might decline to order a debtor to perform covenants in a Subject Document.

(d)    Unenforceability of Certain Provisions. Provisions contained in the Securities or the Subject Documents which require waivers or amendments to be made only in writing may be unenforceable or ineffective, in whole or in part. The inclusion of such provisions, however, does not render any of the Securities or the Subject Documents invalid as a whole.

(e)    Choice of New York Law and Forum. To the extent that any of our opinions relate to the enforceability of the choice of New York law or any choice of New York forum provisions of any Subject Document, our opinion is rendered in reliance upon New York General Obligations Law Sections 5-1401 and 5-1402 and Rule 327(b) of the New York Civil Practice Law and Rules and is subject to the qualification that such enforceability may be limited by

principles of public policy, comity and constitutionality. We express no opinion as to whether a United States federal court would have subject-matter or personal jurisdiction over a controversy arising under the Subject Documents.
