The Company and the Guarantor, subject to Section 3(b), will comply with the requirements of Rule 430B and Rule 433 and notify the Representatives immediately, and confirm the notice in writing, (i) of the receipt of any comments from the Commission to the Registration Statement, General Disclosure Package or the Prospectus, (ii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Pre-Pricing Prospectus or the Prospectus or any Issuer Free Writing Prospectus or for additional information in connection therewith, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of the Pre-Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement to any of the foregoing or any notice from the Commission objecting to the use of the form of the Registration Statement or any post-effective amendment thereto, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction or of the loss or suspension of any exemption from any such qualification, or of the initiation or threatening of any proceedings for any of such purposes, or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (iv) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities. Subject to sub-section (e) below and other than as provided for therein, the Company and the Guarantor will make every reasonable effort to prevent the issuance of any stop order and the suspension or loss of any qualification of the Securities for offering or sale and any loss or suspension of any exemption from any such qualification, and if any such stop order is issued, or any such suspension or loss occurs, to obtain the lifting thereof at the earliest possible moment. The Company shall pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1)(i) of the 1933 Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the 1933 Act Regulations, except to the extent such filing fees have been paid prior to the date hereof.

(b) Filing of Amendments. The Company and the Guarantor will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement, any Issuer Free Writing Prospectus or any amendment, supplement or revision to the Pre-Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus, whether pursuant to the 1933 Act or otherwise, and the Company will furnish the Representatives with copies of any such documents within a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object promptly after reasonably notice thereof. The Company has given the Representatives notice of any filings made pursuant to the 1934 Act or the 1934 Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time through the Closing Time (or, if later, through the end of the period during which the Prospectus is required (or, but for the provisions of Rule 172, would be required) to be delivered by applicable law (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise)) and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object promptly after reasonable notice thereof.

12

(c) Delivery of Registration Statements. The Company and the Guarantor have furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, copies of the Registration Statement and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof) and copies of all consents and certificates of experts.

(d) Continued Compliance with Securities Laws. The Company and the Guarantor will comply with the 1933 and 1934 Acts and Regulations so as to permit the completion of the distribution of the Securities as contemplated by this Agreement, the General Disclosure Package and the Prospectus. If at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by the applicable law to be delivered in connection with sales of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), any event shall occur or condition shall exist as a result of which it is necessary to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) so that the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, will not 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 under which they were made or then prevailing, not misleading or if it is necessary to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) in order to comply with the requirements of the 1933 and 1934 Acts and Regulations, the Company and the Guarantor will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement and will promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission or to comply with such requirements, and, in the case of an amendment or port-effective amendment to the Registration Statement, the Company and the Guarantor will use its best efforts to have such amendment declared or become effective as soon as practicable and the Company and the Guarantor will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time an Issuer Free Writing Prospectus conflicts with the information contained in the Registration Statement or if an event shall occur or condition shall exist as a result of which it is necessary to amend or supplement such Issuer Free Writing Prospectus so that it will not include an 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 under which they were made or then prevailing, not misleading, or if it is necessary to amend or supplement such Issuer Free Writing Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company and the Guarantor will promptly notify the Representatives of such event or condition and of its

13

intention to file such amendment or supplement and will promptly prepare and, if required by the 1933 Act or the 1933 Act Regulations, file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such requirements, and the Company and the Guarantor will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(e) Blue Sky and Other Qualifications. The Company and the Guarantor will endeavor, in cooperation with the Underwriters, to qualify the Securities for offer and sale, or to obtain an exemption for the Securities to be offered or sold, under the applicable securities or blue sky laws of such jurisdictions as the Representatives shall reasonably request and to continue such qualification in effect so long as reasonably required for distribution of the Securities; provided that neither the Company nor the Guarantor shall be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(f) Rule 158. The Company and the Guarantor will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(g) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Pre-Pricing Prospectus and the Prospectus under “Use of Proceeds.”

(h) Restriction on Sale of Securities. During the period beginning on the date hereof and continuing to and including the Closing Time, neither the Company nor the Guarantor will offer, sell, contract to sell or otherwise dispose of any debt securities of or guaranteed by the Company or the Guarantor which mature more than one year after the Closing Time, which are denominated in United States dollars, euros or pounds sterling and which are substantially similar to the Securities, including the filing (or participation in filing) of a registration statement with the Commission in respect of any such debt securities (other than the Securities), or publicly announcing an intention to effect any such transaction, without the prior written consent of the Representatives, which consent will not be unreasonably withheld. For purposes of this clause (h), such consent shall be deemed to be given by the Representatives to the concurrent offering by the Guarantor and CRH SMW Finance Designated Activity Company of the 5.200% Guaranteed Notes due 2029.

(i) Reporting Requirements. The Company and the Guarantor, during the period when the Prospectus is required (or, but for the provisions of Rule 172, would be required) by applicable law to be delivered (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), will file all documents required to be filed with the Commission pursuant to the 1934 Act and the 1934 Act Regulations within the time periods required by the 1934 Act and the 1934 Act Regulations.

14

(j) Preparation of Prospectus. Immediately following the execution of this Agreement, the Company and the Guarantor will, subject to Section 3(b) hereof, prepare the Prospectus, which shall contain the public offering price and terms of the Securities, the plan of distribution thereof and such other information as may be required by the 1933 Act or the 1933 Act Regulations or as the Representatives and the Company or the Guarantor may deem appropriate, and will file or transmit for filing with the Commission, in accordance with the provisions of Rule 430B and in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), the Prospectus.

(k) New Registration Statement. If, immediately prior to the third anniversary of the initial effective date of the Registration Statement (the “Renewal Deadline”), any of the Securities remains unsold by the Underwriters, the Company and the Guarantor will, prior to the Renewal Deadline, if they have not already done so and are eligible to do so, file a new automatic shelf registration statement relating to the Securities, and notify the Representatives when such filing has been made. If the Guarantor is no longer eligible to file an automatic shelf registration statement, the Company and the Guarantor will, prior to the Renewal Deadline, if they have not already done so, file a new registration statement relating to the Securities, and notify the Representatives when such filing has been made and use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline and will take all other action as is necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the expired registration statement relating to the Securities. References in this Agreement to the “Registration Statement” shall include any such new registration statement from and after the time it is filed with the Commission, mutatis mutandis.

(l) DTC. The Company and the Guarantor will use their best efforts to permit the Securities to be eligible for clearance and settlement through DTC.

(m) Pricing Term Sheet. The Company will prepare a pricing term sheet (the “Pricing Term Sheet”) reflecting the final terms of the Securities, in substantially the form attached hereto as Exhibit C and otherwise in form and substance satisfactory to the Representatives, and shall file such Pricing Term Sheet as an “issuer free writing prospectus” pursuant to, and as required by, Rule 433; provided that the Company shall furnish the Representatives with copies of any such Pricing Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall object.

(n) NYSE Listing. The Company and Guarantor will use their reasonable best efforts to procure the admission of the Securities to listing on NYSE.

SECTION 4. Payment of Expenses.

(a) Expenses. Whether or not the transactions contemplated hereby are consummated or this Agreement is terminated, each of the Company and the Guarantor, jointly and severally, covenant and agree to pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, or thereunder, including without limiting the generality of the foregoing, all costs and expenses (i) incident to the preparation, issuance, execution, authentication

15

(b) Termination of Agreement. If this Agreement is terminated by the Representatives in accordance with the provisions of Section 5 hereof, the Company and the Guarantor shall reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters. If this Agreement is terminated by the Representatives in accordance with the provisions of Section 9 hereof, the Company and the Guarantor shall reimburse non-defaulting Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters.

SECTION 5. Conditions of Underwriters’ Obligations. The obligations of the several Underwriters hereunder are subject to the satisfaction of the following conditions:

(a) Effectiveness of Registration Statement. The Registration Statement shall have become effective, and no stop order suspending the effectiveness of the Registration Statement shall have been issued under the 1933 Act or proceedings therefor initiated or, to the knowledge of the Company or the Guarantor, threatened by the Commission, and any request on the part of the Commission for additional information shall have been complied with to the reasonable satisfaction of the Representatives and the Commission shall not have notified the Company or the Guarantor of any objection to the use of the form of the Registration Statement. The Prospectus shall have been filed with the Commission in the manner and within the time period required by Rule 424(b) (without reliance upon Rule 424(b)(8)) and each Issuer Free Writing Prospectus required to be filed with the Commission shall have been filed in the manner and within the time period required by Rule 433.

16

The Representatives shall have received on and as of the Closing Time a certificate of each of an executive officer of the Company and the Guarantor, with specific knowledge, respectively, about the Company’s and Guarantor’s financial matters, satisfactory to the Representatives (i) to the effect set forth in Sections 5(b), 5(c) and 5(d) and (ii) to the further effect that no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company or the Guarantor, are threatened by the Commission and the Commission has not notified the Company or the Guarantor of any objection to the use of the form of the Registration Statement. The officers signing and delivering such certificates may certify to the best of their knowledge, but shall sign and deliver the certificates solely in their capacities as officers of the Company and the Guarantor, respectively, and not in their individual capacities.

The Representatives may, in their sole discretion, waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder.

18

SECTION 6. Indemnification. The Company and the Guarantor jointly and severally agree to indemnify and hold harmless each Underwriter, its affiliates, directors and officers, and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all losses, claims, damages and liabilities (including without limitation the legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted) caused by any untrue statement or alleged untrue statement of a material fact in the Registration Statement or part thereof (and any amendment thereto) or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in the Pre-Pricing Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or in any “issuer information” (as defined in Rule 433) or “road show” (as defined in Rule 433) that does not constitute an Issuer Free Writing Prospectus or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company or the Guarantor in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriters are (i) the names of the Underwriters at the bottom of the front and back cover pages of the Prospectus and (ii) the sixth and seventh paragraphs of text under the caption “Underwriting” on pages S-35 of the Prospectus relating to over-allotment, stabilization and penalty bids.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantor and their respective directors and officers and each person who controls the Company or the Guarantor within the meaning of Section 15 of the 1933 Act and Section 20 of the 1934 Act, to the same extent as the foregoing indemnity from, respectively, the Company and the Guarantor to each Underwriter, but only with reference to information relating to such Underwriter furnished to the Company or the Guarantor in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Pre-Pricing Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or in any “issuer information” (as defined in Rule 433) filed or required to be filed pursuant to Rule 433(d). The Company and the Guarantor hereby agree and acknowledge that the only information that the Underwriters through the Representatives have furnished to the Company expressly for use in the Registration Statement, the Pre-Pricing Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) are (i) the names of the Underwriters at the bottom of the front and back cover pages of the Prospectus and (ii) the sixth and seventh paragraphs of text under the caption “Underwriting” on pages S-35 of the Prospectus relating to over-allotment, stabilization and penalty bids.

19

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 indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Person”) in writing, but the omission to notify the indemnifying party shall not relieve that indemnifying party from any liability which it may have to any indemnified party otherwise than under such subsection. In case any notice of any such action shall be given by any Indemnified Person, the Indemnifying Person shall be entitled to participate therein and, to the extent that the Indemnifying Person shall wish, jointly with any other indemnifying party similarly notified, assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Person. 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 in writing to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) 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 interests between them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding 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 reimbursed as they are incurred. Any such separate firm for the Underwriters, each affiliate of any Underwriter which assists such Underwriter in the distribution of the Securities and such control persons of the Underwriters shall be designated in writing by the Representatives and any such separate firm for the Company, the Guarantor, directors, officers and such control persons of the Company and the Guarantor or authorized representatives as shall be designated in writing by the Guarantor.

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 any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect the settlement or compromise or consent to the entry of any judgment of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding.

SECTION 7. Contribution. If the indemnification provided for in the first and second paragraphs of Section 6 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities (or such proceedings in respect thereof) referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the expenses of and amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (or such proceedings in respect thereof) (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantor on the one hand and the Underwriters on the other hand from

20

the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantor on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantor on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Securities (before deducting expenses) received by the Company and the Guarantor and the total underwriting discounts and the commissions received by the Underwriters bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantor on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantor on the one hand or by the 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, the Guarantor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (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 the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities (or such proceedings in respect thereof) referred to in the immediately preceding paragraph 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 investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total discounts and commissions received by it 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to the respective principal amount of the Securities set forth opposite their names in Exhibit I hereto, and not joint.

The remedies provided for in Section 6 and this Section 7 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 indemnity and contribution agreements contained in Section 6 and this Section 7 and the representations and warranties of the Company and the Guarantor set forth herein shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, the Guarantor, their respective officers or directors or any other person controlling the Company or the Guarantor and (iii) acceptance of and payment for any of the Securities.

21

SECTION 8. Termination of Agreement.

(c) Termination; General. Notwithstanding anything herein contained, this Agreement may be terminated in the absolute discretion of the Representatives, by notice given to the Company and the Guarantor if after the execution and delivery of this Agreement and prior to the Closing Time (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of Euronext Dublin, NYSE, NYSE American, the Financial Industry Regulatory Authority, Inc., the Chicago Board Options Exchange, the Chicago Mercantile Exchange, or the Chicago Board of Trade, (ii) trading of any securities of or guaranteed by the Company or the Guarantor shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York or Ireland shall have been declared by either Federal or New York State or Irish authorities, as applicable, or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, in the judgment of the Representatives, makes it impracticable to market the Securities on the terms and in the manner contemplated in the Prospectus.

(d) Liabilities. If this Agreement is terminated pursuant to this Section 8, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and except that Sections 1, 6, 7, 10, 11, 12, 13, 14, 16, 17, 18 and 19 hereof shall survive such termination and remain in full force and effect.

(e) Expenses Upon Termination. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or the Guarantor to comply with the terms or to fulfill any of the conditions hereof, or if for any reason the Company or the Guarantor shall be unable to perform its obligations hereunder or any condition of the Underwriters’ obligations cannot be fulfilled other than due to the termination of this Agreement by or through default of any Underwriters, the Company and the Guarantor jointly and severally agree to reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and expenses of their counsel) reasonably and properly incurred by such Underwriters in connection with this Agreement or the offering of the Securities.

SECTION 9. Default by One or More of the Underwriters. If, at the Closing Time, any one or more of the Underwriters shall fail or refuse to purchase Securities which it or they have agreed to purchase hereunder, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Securities, the other Underwriters shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Exhibit I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Underwriter has agreed to purchase pursuant hereto be increased pursuant to this Section 9 by an amount in excess of one-tenth of such principal amount of Securities without the written consent of such Underwriter. If, at the Closing Time, any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal

22

amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased, and arrangements satisfactory to the Representatives, the Company and the Guarantor for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company and the Guarantor. In any such case either the Representatives, the Company or the Guarantor shall have the right to postpone the Closing Time, but in no event for longer than seven days, in order that the required changes, if any, in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter hereunder.

SECTION 10. Notice. Any action by the Underwriters hereunder may be taken by the Representatives jointly, and any such action taken by the Representatives jointly shall be binding upon the Underwriters.

For the purposes of clarity, the parties hereto agree that all free writing prospectuses, if any, listed in Exhibit D hereto are Permitted Free Writing Prospectuses.

SECTION 16. Absence of Fiduciary Relationship. The Company and the Guarantor jointly and severally acknowledge and agree that:

(a) each of the Underwriters is acting solely as an underwriter in connection with the sale of the Securities and no fiduciary, advisory or agency relationship between the Company or the Guarantor, on the one hand, and any of the Underwriters, on the other hand, has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether or not any of the Underwriters has advised or is advising the Company or the Guarantor on other matters;

(b) the public offering price of the Securities and the price to be paid by the Underwriters for the Securities set forth in this Agreement were established by the Company and the Guarantor following discussions and arms-length negotiations with the Representatives;

(c) they are capable of evaluating and understanding, and understand and accept, the terms, risks and conditions of the transactions contemplated by this Agreement;

(d) they are aware that the Underwriters and their respective affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company or the Guarantor and that none of the Underwriters has any obligation to disclose such interests and transactions to the Company or the Guarantor by virtue of any fiduciary, advisory or agency relationship or otherwise; and

(e) they waive, to the fullest extent permitted by law, any claims they may have against any of the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that none of the Underwriters shall have any liability (whether direct or indirect, in contract, tort or otherwise) to it in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on its behalf or in right of it or the Company or the Guarantor or any stockholders, employees or creditors of Company or the Guarantor.

SECTION 17. Consent to Jurisdiction. The Guarantor irrevocably submits to the non-exclusive jurisdiction of any federal or state court in the City, County and State of New York, United States of America, in any legal suit, action or proceeding based on or arising under this Agreement and agrees that all claims in respect of such suit or proceeding may be determined in any such court. The Guarantor waives, to the extent permitted by law, the defense of an inconvenient forum or objections to personal jurisdiction with respect to the maintenance of such legal suit, action or proceeding. The Guarantor hereby designates and appoints CT Corporation System, 28 Liberty Street New York, New York 10005, USA (the “Process Agent”), as its authorized agent, upon whom process may be served in any such legal suit, action or proceeding,

26

it being understood that the designation and appointment of the Process Agent as such authorized agent shall become effective immediately without any further action on the part of the Guarantor. Such appointment shall be irrevocable to the extent permitted by applicable law and subject to the appointment of a successor agent in the United States on terms substantially similar to those contained in this Section 17 and reasonably satisfactory to the Representatives. If the Process Agent shall cease to act as agent for services of process, the Guarantor shall appoint, without unreasonable delay, another such agent, and notify the Representatives of such appointment. The Guarantor represents to the Underwriters that it has notified the Process Agent of such designation and appointment and that the Process Agent has accepted the same in writing. The Guarantor hereby authorizes and directs the Process Agent to accept such service. The Guarantor further agrees that service of process upon the Process Agent and written notice of said service to such party shall be deemed in every respect effective service of process upon such party in any such legal suit, action or proceeding. Nothing herein shall affect the right of any Underwriter or any person controlling any Underwriter to serve process in any other manner permitted by law.

SECTION 18. Waiver of Jury Trial. The Company, the Guarantor and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to a trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 19. Judgment Currency. If for the purpose of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Representatives could purchase United States dollars with such other currency in New York City on the business day preceding that on which final judgment is given. The joint and several obligations of the Company and the Guarantor in respect of any sum due from either of them to any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first Business Day following receipt by such Underwriter of any sum adjudged to be so due in such other currency on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to such Underwriter hereunder, each of the Company and the Guarantor jointly and severally agrees, as a separate obligation and notwithstanding any judgment, to indemnify such Underwriter against such loss.

SECTION 20. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

27

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
