XXXXXX LABORATORIES

Debt Securities

Underwriting Agreement

November 6, 2007

To the Representatives of the

several Underwriters named in the

respective Pricing Agreements

hereinafter described.

Ladies and Gentlemen:

From time to time Xxxxxx Laboratories, an Illinois corporation (the “Company”), proposes to enter into one or more Pricing Agreements (each a “Pricing Agreement”) in the form of Annex I hereto, with such additions and deletions as the parties thereto may determine, and, subject to the terms and conditions stated herein and therein, to issue and sell to the firms named in Schedule I to the applicable Pricing Agreement (such firms constituting the “Underwriters” with respect to such Pricing Agreement and the securities specified therein) certain of its debt securities (the “Securities”) specified in Schedule II to such Pricing Agreement (with respect to such Pricing Agreement, the “Designated Securities”).

The terms and rights of any particular issuance of Designated Securities shall be as specified in the Pricing Agreement relating thereto and in or pursuant to the indenture (the “Indenture”) identified in such Pricing Agreement.

Particular sales of Designated Securities may be made from time to time to the Underwriters of such Securities, for whom the firms designated as representatives of the Underwriters of such Securities in the Pricing Agreement relating thereto will act as representatives (the “Representatives”). The term “Representatives” also refers to a single firm acting as sole representative of the Underwriters and to an Underwriter or Underwriters who act without any firm being designated as its or their representatives. This Underwriting Agreement (this “Agreement”) shall not be construed as an obligation of the Company to sell any of the Securities or as an obligation of any of the Underwriters to purchase the Securities. The obligation of the Company to issue and sell any of the Securities and the obligation of any of the Underwriters to purchase any of the Securities shall be evidenced by the Pricing Agreement with respect to the Designated Securities specified therein. Each Pricing Agreement shall specify the aggregate principal amount of such Designated Securities, the initial public offering price of such Designated Securities, the purchase price to the Underwriters of such Designated Securities, the names of the Underwriters of such Designated Securities, the names of the Representatives of such Underwriters and the principal amount of such Designated Securities to be purchased by each Underwriter and shall set forth the date, time and manner of delivery of such Designated Securities and payment therefore. The Pricing Agreement shall also specify (to the extent not set forth in the Indenture and the registration statement and prospectus with respect

thereto) the terms of such Designated Securities. A Pricing Agreement shall be in the form of an executed writing (which may be in counterparts) and may be evidenced by an exchange of telegraphic communications or any other rapid transmission device designed to produce a written record of communications transmitted. The obligations of the Underwriters under this Agreement and each Pricing Agreement shall be several and not joint.

The Company has filed with the U.S. Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement, as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), on Form S-3 (File No. 333-132104) relating to the Securities. The Company proposes to file pursuant to Rule 424 under the Securities Act a prospectus supplement specifically relating to the Designated Securities and reflecting the terms of the Designated Securities and plan of distribution arising from the Underwriting Agreement (the “Prospectus Supplement”). The term “Registration Statement”, as used with respect to a particular issue of Designated Securities, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Securities Act as such section applies to the Company and the Underwriters for the Designated Securities pursuant to Rule 430B(f)(2) under the Securities Act (the “Effective Time”), including (i) all documents then filed as a part thereof or incorporated by reference or deemed to be incorporated by reference therein and (ii) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act, to the extent such information is deemed, pursuant to Rule 430B(f)(1) under the Securities Act, to be part of the Registration Statement at the Effective Time. The term “Basic Prospectus” means the prospectus included in the Registration Statement exclusive of the Prospectus Supplement. The term “Prospectus” means the Basic Prospectus together with the Prospectus Supplement in the form first used in the offering of the Designated Securities. The term “Preliminary Prospectus” means a preliminary prospectus supplement specifically relating to the Designated Securities together with the Basic Prospectus. The term “Permitted Free Writing Prospectus” as used herein means the documents relating to the Designated Securities attached as Schedule III to the Pricing Agreement for such Designated Securities.

In connection with the participation of the Underwriters in the offering of the Designated Securities pursuant to the terms hereof and the applicable Pricing Agreement, and in recognition of the arm’s length contractual relationship between the Underwriters and the Company created hereby and the applicable Pricing Agreement (including the arm’s length negotiation of the terms of the offering), the Company acknowledges and agrees that (i) the Underwriters are not acting as financial advisors or fiduciaries to the Company or as agents of the Company in any respect; (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any; and (iii) the Underwriters may have interests that differ from those of the Company. In further recognition of such arm’s length contractual relationship and the limitations thereof, the Company hereby acknowledges and agrees that (a) no Underwriter is advising the Company as to any legal, tax, investment, accounting or regulatory matter and the Company shall consult with its own advisors concerning such matters, including conducting with such advisors its own independent analysis of such offering, and the Underwriters shall have no responsibility or liability to the Company with respect thereto; and (b) the Underwriters shall have no responsibility or liability to the Company in respect of any lawful arrangement they may have with other parties in connection with such offering, including arrangements that may be

viewed as creating a potential or actual conflict of interest between the Company and any of the Underwriters. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of Designated Securities.

(ix) The Registration Statement at the date of the first use of the Prospectus, the Prospectus and the Permitted Free Writing Prospectuses, if any, as of their respective dates, as amended or supplemented and any further amendments and supplements thereto made by the Company prior to the Time of Delivery for the Designated Securities (other than the financial statements and related schedules and other financial and statistical data therein, as to which such counsel need express no opinion) comply as to form in all material respects with the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations thereunder; and such counsel does not know of any amendment to the Registration Statement required to be filed or any contracts or other documents of a character required to be filed as an exhibit to the Registration Statement or required to be incorporated by reference into the Prospectus as amended or supplemented or required to be described in the Registration Statement or the Prospectus as amended or supplemented which are not filed or incorporated by reference or described as required.

In addition, such counsel shall state that she or members of her staff have participated in conferences with other officers and representatives of the Company, representatives of special counsel and the independent registered public accountants for the Company and the Underwriters and their representatives at which the contents of the Registration Statement, the General Disclosure Package and the Prospectus and related matters were discussed. However, except as specifically noted above, such counsel is not passing upon and assumes no responsibility for the

accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus, or making any representation that she has independently verified or checked the accuracy, completeness or fairness of such statements. Notwithstanding the foregoing, no facts have come to such counsel’s attention that would lead her to believe that (except for financial statements and schedules and other financial and related statistical data as to which such counsel expresses no belief) (i) the Registration Statement (or any post-effective amendment thereto), as of the last time it became effective preceding the time the applicable Pricing Agreement was entered into, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) the General Disclosure Package as of the Pricing Effective Time contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) the Prospectus (or any amendment or supplement thereto), as of its date and as of the Time of Delivery, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Xxxxx Xxxxx LLP, special counsel for the Company, or other outside counsel to the Company satisfactory to the Representatives, shall have furnished to the Representatives its written opinion, dated the Time of Delivery for such Designated Securities, in form and substance satisfactory to the Representatives, to the effect that:

(i) This Agreement and the Pricing Agreement with respect to the Designated Securities have been duly authorized, executed and delivered by the Company;

(ii) The Designated Securities have been duly authorized, executed, issued and delivered and constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture, subject, as to enforcement, to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles; and the Designated Securities and the Indenture conform in all material respects to the descriptions thereof in the Prospectus as amended or supplemented and in the Permitted Free Writing Prospectuses, if any;

(iii) The Indenture has been duly authorized, executed and delivered by the Company and duly qualified under the Trust Indenture Act and, at the Time of Delivery for such Designated Securities (as defined in Section 3 hereof), assuming the Indenture has been duly authorized, executed and delivered by the Trustee, the Indenture will constitute a valid and legally binding instrument, enforceable in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles; and

(iv) The Registration Statement at the date of the first use of the Prospectus, the Prospectus and the Permitted Free Writing Prospectuses, if any, as of their respective dates, as amended or supplemented and any further amendments and supplements thereto made by the Company prior to the Time of Delivery for the Designated Securities (other than the financial statements and related schedules and other financial and related statistical data

therein, as to which such counsel need express no opinion) comply as to form in all material respects with the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations thereunder; and such counsel does not know of any amendment to the Registration Statement required to be filed or any contracts or other documents of a character required to be filed as an exhibit to the Registration Statement or required to be incorporated by reference into the Prospectus as amended or supplemented or required to be described in the Registration Statement or the Prospectus as amended or supplemented which are not filed or incorporated by reference or described as required.

In addition, such counsel has participated in conferences with officers and representatives of the Company, representatives of the independent registered public accountants for the Company and the Underwriters and their representatives at which the contents of the Registration Statement, the General Disclosure Package and the Prospectus and related matters were discussed. However, except as specifically noted above, such counsel is not passing upon and assumes no responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus, or making any representation that it has independently verified or checked the accuracy, completeness or fairness of such statements. Notwithstanding the foregoing, no facts have come to such counsel’s attention that have lead it to believe that (except for financial statements and schedules and other financial and related statistical data as to which such counsel expresses no belief) (i) the Registration Statement (or any post-effective amendment thereto), as of the last time it became effective preceding the time the applicable Pricing Agreement was entered into, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) the General Disclosure Package as of the Pricing Effective Time contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) the Prospectus (or any amendment or supplement thereto), as of its date and as of the Time of Delivery, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(e) On the date of the Pricing Agreement for such Designated Securities at a time prior to the execution of the Pricing Agreement with respect to such Designated Securities and at the Time of Delivery for such Designated Securities, the independent accountants of the Company who have certified the financial statements of the Company and its subsidiaries included or incorporated by reference in the Registration Statement shall have furnished to the Representatives a letter, dated the effective date of the Registration Statement or the date of the most recent report filed with the Commission containing financial statements and incorporated by reference in the Registration Statement, if the date of such report is later than such effective date, and a letter dated such Time of Delivery, respectively, to the effect set forth in Annex II hereto, and with respect to such letter dated such Time of Delivery, as to such other matters as the Representatives may reasonably request prior to execution of the Pricing Agreement and in form and substance satisfactory to the Representatives;

(f) (i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest financial statements included or incorporated by reference in

the Prospectus as amended or supplemented any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus as amended or supplemented, and (ii) since the respective dates as of which information is given in the Prospectus as amended or supplemented there shall not have been any change in the consolidated capital stock or any increase in the consolidated long-term debt of the Company and its subsidiaries or any change, or any development involving a prospective change, in or affecting the management, financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Prospectus as amended or supplemented, the effect of which, in any such case described in clause (i) or (ii), is in the reasonable judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Designated Securities on the terms and in the manner contemplated in the Prospectus as amended or supplemented relating to the Designated Securities;

(g) On or after the date of the Pricing Agreement relating to the Designated Securities (i) no downgrading shall have occurred, nor shall any notice have been given of any intended or potential downgrading, in the rating accorded the Company, any of the securities of the Company or any of its subsidiaries by any “nationally recognized statistical rating organization,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities;

(h) On or after the date of the Pricing Agreement relating to the Designated Securities, there shall not have occurred any of the following: (i) a suspension of trading of the Company’s common shares by the Commission, the New York Stock Exchange or the Chicago Stock Exchange precipitated by the announcement by the Company of a material adverse event with respect to the Company’s business or financial position; (ii) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities in New York declared by either Federal or New York State authorities; (iv) a material disruption in commercial banking or securities settlement, payment or clearance services in the United States; or (v) the outbreak or escalation of hostilities or the occurrence of any other calamity or crisis or any material adverse change in financial markets, if the effect of any such event specified in this clause (v) in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Designated Securities on the terms and in the manner contemplated by the Prospectus as amended and supplemented relating to the Designated Securities; and

(i) The Company shall have furnished or caused to be furnished to the Representatives at the Time of Delivery for the Designated Securities a certificate or certificates of officers of the Company satisfactory to the Representatives as to the accuracy of the representations and warranties of the Company herein at and as of such Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in subsections (a), (f) and (g) of this Section.

6. Indemnity and Contribution

(a) The Company will indemnify and hold harmless each Underwriter, its directors, officers and employees, and each person, if any, who controls any Underwriter (within the meaning of the Securities Act), from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or supplemented, any Permitted Free Writing Prospectus and any other prospectus relating to the Securities, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter, director, officer, employee or controlling person for any legal or other expenses reasonably incurred by such Underwriter, director, officer, employee or controlling person in connection with investigating or defending any such loss, damage, liability, action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or supplemented, any Permitted Free Writing Prospectus and any other prospectus relating to the Securities, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by any Underwriter of Designated Securities through the Representatives expressly for use in the Prospectus as amended or supplemented relating to such Securities or in any Permitted Free Writing Prospectus; and, provided, further, that the foregoing indemnity agreement with respect to the Prospectus or any Permitted Free Writing Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such loss, liability, claim, damage or expense purchased Securities, or any person controlling such Underwriter, if the Company provides a copy of an amendment or supplement to the Prospectus or to a Permitted Free Writing Prospectus as theretofore provided to such Underwriter by the Company (with notice that such amendment or supplement contains additional or different material information from that previously provided) sufficiently far enough in advance of the time of sale in order to enable such Underwriter to convey such amendment or supplement to the purchaser of the Securities, and such amendment or supplement (x) was not conveyed by or on behalf of such Underwriter to such person at or prior to the entry into the contract of sale of the Securities by such person, and (y) would have cured the defect giving rise to such loss, liability, claim, damage or expense.

(b) Each Underwriter will indemnify and hold harmless the Company, its directors, officers and employees and each person, if any, who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages or liabilities to which the Company or any director, officer, employee or controlling person of the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or

supplemented, any Permitted Free Writing Prospectus and any other prospectus relating to the Securities, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus as amended or supplemented, any Permitted Free Writing Prospectus and any other prospectus relating to the Securities, or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and each Underwriter will reimburse the Company or any director, officer, employee or controlling person of the Company for any legal or other expenses reasonably incurred by the Company or such director, officer, employee or controlling person of the Company in connection with investigating or defending any such loss, damage, liability, action or claim as such expenses are incurred.

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

(d) If the indemnification provided for in paragraph (a) or (b) of this Section 6 is unavailable to an indemnified party or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters of the Designated Securities on the other from the offering of the Designated Securities to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters of the Designated Securities on the

other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by such Underwriters. 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 required to be stated therein or necessary in order to make the statements therein not misleading relates to information supplied by the Company on the one hand or such Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this subsection (d) 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 which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the applicable Designated Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which 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 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 party at law or in equity. The obligations of the Underwriters of Designated Securities in this subsection (d) to contribute are several in proportion to their respective underwriting obligations with respect to such Securities and not joint.

(e) The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and employee of any Underwriter and to each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 6 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act.

7. Defaulting Underwriters.

(a) If any Underwriter shall default in its obligation to purchase the Designated Securities which it has agreed to purchase under the Pricing Agreement relating to such Designated Securities, the Representatives may in their discretion arrange for themselves or

another party or other parties to purchase such Designated Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Designated Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Designated Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of such Designated Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Designated Securities, the Representatives or the Company shall have the right to postpone the Time of Delivery for such Designated Securities for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus as amended or supplemented, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to the Pricing Agreement with respect to such Designated Securities.

(b) If, after giving effect to any arrangements for the purchase of the Designated Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Designated Securities which remains unpurchased does not exceed one-tenth of the aggregate principal amount of the Designated Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Designated Securities which such Underwriter agreed to purchase under the Pricing Agreement relating to such Designated Securities and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Designated Securities which such Underwriter agreed to purchase under such Pricing Agreement) of the Designated Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; provided, however, that in no event shall the principal amount of Designated Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 7 by an amount in excess of one-ninth of such principal amount of Designated Securities without the written consent of such Underwriter; provided, further, that nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Designated Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Designated Securities which remains unpurchased exceeds one-tenth of the aggregate principal amount of the Designated Securities, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Designated Securities of a defaulting Underwriter or Underwriters, then the Pricing Agreement relating to such Designated Securities shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 4(a)(viii) hereof and the indemnity and contribution agreements in Section 6 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

8. Survival. The indemnity and contribution provisions contained in Section 6 and the representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any termination of this Agreement, any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter, officer, director or employee or any controlling person of any Underwriter, or by or on behalf of the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

9. Termination; Liability. If any Pricing Agreement shall be terminated pursuant to Section 7 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Designated Securities covered by such Pricing Agreement except as provided in Section 4(a)(viii) and Section 6 hereof; but, if for any other reason Designated Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Designated Securities, but the Company shall then be under no further liability to any Underwriter with respect to such Designated Securities except as provided in Section 4(a)(viii) and Section 6 hereof.

10. Notices. In all dealings hereunder, the Representatives of the Underwriters of Designated Securities shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in the Pricing Agreement.

All statements, requests, notices and agreements hereunder shall be in writing and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the address of the Representatives as set forth in the Pricing Agreement; and if to the Company shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Registration Statement: Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 6(c) hereof shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, which address will be supplied to the Company by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

11. Successors. This Agreement and each Pricing Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Section 6 and Section 8 hereof, the officers, directors and employees of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement or any such Pricing Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

12. Timing. Time shall be of the essence of each Pricing Agreement. As used herein, “Business Day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

13. Applicable Law. THIS AGREEMENT AND EACH PRICING AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

14. Counterparts. This Agreement and each Pricing Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

15. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

16. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of Designated Securities, represent the entire agreement between the Company and each of the Underwriters with respect to the preparation of any Preliminary Prospectus, the Prospectus, the Permitted Free Writing Prospectus, the conduct of the offering and the purchase and sale of Designated Securities.

(i) They are independent registered public accountants with respect to the Company within the meaning of the Securities Act and the applicable published rules and regulations thereunder;

(ii) In their opinion, the consolidated financial statements and any financial statement schedules audited by them and included or incorporated by reference in the Registration Statement or the Prospectus comply as to form in all material respects with the applicable accounting requirements of the Securities Act or the Exchange Act, as applicable, and the related published rules and regulations thereunder; and they have made a review in accordance with standards established by the Public Company Accounting Oversight Board (United States) of the condensed consolidated interim financial statements of the Company for the periods specified in such letter, as indicated in their reports thereon, copies of which have been furnished to the representative or representatives of the Underwriters (the “Representatives”);

(iii) The unaudited selected financial information with respect to the consolidated results of operations and financial position of the Company for the five most recent fiscal years included in the Prospectus and included or incorporated by reference in Item 6 of the Company’s Annual Report on Form 10-K for the most recent fiscal year agrees with the corresponding amounts (after restatement where applicable) in the audited consolidated financial statements for the five such fiscal years which were included or incorporated by reference in the Company’s Annual Reports on Form 10-K for such fiscal years;

(iv) They have compared the information in the Prospectus under selected captions with the disclosure requirements of Regulation S-K and on the basis of limited procedures specified in such letter nothing came to their attention as a result of the foregoing procedures that caused them to believe that this information does not conform in all material respects with the disclosure requirements of Items 301, 302, 402 and 503(d), respectively, of Regulation S-K;

(v) On the basis of performing the procedures specified by the Public Company Accounting Oversight Board (United States) for a review of interim financial information as described in SAS No. 100, Interim Financial Information, on the unaudited condensed consolidated financial statements included in the Company’s Quarterly Report on Form 10-Q for the periods specified in such letter, and making inquiries of officials of the Company who have responsibility for financial and accounting matters, nothing came to their attention that caused them to believe that:

(A) the unaudited condensed consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included or incorporated by reference in the Company’s Quarterly Reports on Form 10-Q incorporated by reference in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act as it applies to Form 10-Q and the related published rules and regulations thereunder or that any material modification should be made to those financial statements for them to be in conformity with generally accepted accounting principles; and

(B) any other unaudited income statement data and balance sheet items included in the Prospectus do not agree with the corresponding items in the unaudited consolidated financial statements from which such data and items were derived.

(A) as of a specified date not more than four days prior to the date of such letter, there have been any changes in the consolidated common shares, net of treasury shares (other than incentive stock plan transactions or purchases of common shares authorized for purchase by the Board of Directors) or any increase in the consolidated long-term debt of the Company and its subsidiaries, or any decreases in consolidated net current assets or net assets or other items specified by the Representatives, or any increases in any items specified by the Representatives, in each case as compared with amounts shown in the latest balance sheet included or incorporated by reference in the Prospectus, except in each case for changes, increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter;

(B) for the period from the date of the latest financial statements included or incorporated by reference in the Prospectus to the specified date referred to in clause (A) there were any decreases in consolidated net sales or consolidated net income or other items specified by the Representatives, or any increases in any items specified by the Representatives, in each case as compared with the comparable period of the preceding year and with any other period of corresponding length specified by the Representatives, except in each case for increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter; and
