(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 required to be stated therein or 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) upon the advice of counsel to the Company or the Underwriters, it is necessary to amend or supplement the Prospectus to comply with law, the Company will promptly 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 Time of Sale Information 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, not misleading or (ii) upon the advice of counsel to the Company or the Underwriters, it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will promptly 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 Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

     (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. For a period of 45 days after the date of the initial public offering of the Securities, the Company will not, without the prior written consent of the Representatives, (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (ii) enter into any swap or other agreement

that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of the Representatives, other than (A) the Securities to be sold hereunder and the issuance of the Underlying Securities upon conversion thereof, (B) any (i) grant or issuance of any stock options, restricted stock or other awards, (ii) issuance of shares of Common Stock of the Company upon the exercise of options granted, (iii) vesting of or removal or lapse of restrictions on restricted stock or other awards and (iv) deemed acquisitions or transfers upon the cashless exercise of stock options (whether to cover exercise prices or taxes) or upon the forfeiture or cancellation of restricted stock to cover tax payments, in each case, under existing employee benefit plans or agreements, (C) any transfer of shares of Common Stock pursuant to the Company’s 401(k) plan, (D) the filing by the Company of any registration statement with the Commission on Form S-8 relating to the offering of securities pursuant to the terms of the existing employee benefit plans or agreements, (E) shares of Common Stock (or options, warrants or convertible securities in respect thereof) issued in connection with a bona fide merger or acquisition transaction, provided that the Common Stock (or options, warrants or convertible securities in respect thereof) so issued is subject to the terms of a duplicative form of the “lock-up agreement” set forth in Exhibit A attached hereto and (F) the issuance of the Rights pursuant to the Rights Agreement. Notwithstanding the foregoing, if (1) during the last 17 days of the 45-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company becomes publicly known; or (2) prior to the expiration of the 45-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 45-day period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

     (i) Use of Proceeds. The Company will apply the net proceeds from the sale of the Securities as described in the Registration Statement, the Time of Sale Information 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. To the extent not available on the Commission’s EDGAR system or the Company’s website, for a period of two years from the date hereof 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.

     (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.

     3. Certain Agreements of the Underwriters. Each Underwriter hereby represents and agrees that:

     (a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than

(i) a free writing prospectus that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) that was not included (including through incorporation by reference) in the Preliminary Prospectus or a previously filed Issuer Free Writing Prospectus, (ii) the pricing term sheet set forth in Annex A, the press release set forth in Annex B or any Issuer Free Writing Prospectus prepared pursuant to Section 1(a)(iv) or Section 2(c) above, (iii) any free writing prospectus prepared by such underwriter and approved by the Company in advance in writing or (iv) customary filings through the Bloomberg system (each such free writing prospectus referred to in clauses (i), (iii) or (iv), an “Underwriter Free Writing Prospectus”).

     (b) It has not and will not distribute any Underwriter Free Writing Prospectus referred to in clause (a)(i) in a manner reasonably designed to lead to its broad unrestricted dissemination.

     (c) It has not and will not, without the prior written consent of the Company, use any free writing prospectus that contains the final terms of the Securities unless such terms have previously been included in a free writing prospectus filed with the Commission; provided that Underwriters may use a term sheet substantially in the form of Annex A hereto without the consent of the Company.

     (d) It will, pursuant to reasonable procedures developed in good faith, retain copies of each free writing prospectus used or referred to by it, in accordance with Rule 433 under the Securities Act.

     (e) It is not subject to any pending proceeding under Section 8A of the Securities Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the Prospectus Delivery Period).

     4. Purchase of the Shares by the Underwriters. (a) The Company agrees to issue and sell the Firm Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto at a price equal to 98.125% of the principal amount thereof, plus accrued interest if any, from June 7, 2006 to the Closing Date (as defined below).

     (b) In addition, the Company agrees to issue and sell Option Securities to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations and warranties set forth herein and subject to the conditions set forth herein shall have the option to purchase, severally and not jointly, from the Company Option Securities at a price equal to 98.125% of the principal amount of Option Securities purchased by such Underwriter, plus accrued interest if any, from June 7, 2006 to the Additional Closing Date (as defined below). If any Option Securities are to be purchased, the principal amount of Option Securities to be purchased by each Underwriter shall be the principal amount of such Option Securities which bears the same ratio to the aggregate number of Option Securities being purchased as the number of Firm Securities set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 9 hereof) bears to the aggregate number of Firm Securities being purchased from the Company by the several Underwriters, subject, however, to such adjustments to maintain the principal amount of Option Securities purchased by each Underwriter a multiple of $1,000 as the Representatives in their sole discretion shall make.

     (c) J.P. Morgan Securities Inc. has agreed to reimburse the Company for certain out of pocket expenses not to exceed $77,500.

     (d) The Underwriters may, by not less than 2 nor more than 10 Business Days’ prior written notice from the Representatives to the Company, exercise the option to purchase the Option Securities at any time in whole, or from time to time in part. Such notice shall set forth the aggregate number of Option Securities as to which the option is being exercised and the date and time when the Option Securities are to be delivered and paid for which may be the same date and time as the Closing Date (as defined below) but shall not be earlier than the Closing Date nor after the thirteen day period beginning on, and including, the Closing Date.

     (e) The Company understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representative is advisable, and initially to offer the Securities on the terms set forth in the Prospectus. The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

     (f) Payment for and delivery of the Securities shall be made (i) in the case of the Firm Securities at the offices of Davis Polk & Wardwell, 450 Lexington Avenue, New York, New York 10017 at 10:00 A.M., New York City time, on June 7, 2006, or at such other time or place on the same or such other date, not later than the fifth Business Day thereafter, as the Representatives and the Company may agree upon in writing (the time and date of such payment and delivery is referred to herein as the “Closing Date”); or (ii) in the case of the Option Securities, on the date and at the time and place specified by the Representatives in the written notice of the Underwriters’ election to purchase such Option Securities (the time and date of such payment and delivery is referred to herein as the “Additional Closing Date”.)

     (g) Payment for the Securities to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made by wire transfer in immediately available funds to the account specified by the Company to the Representatives against delivery to the nominee of The Depositary Trust Company, for the account of the Underwriters, of a global note representing the Securities purchased on such Closing Date or Additional Closing Date, as the case may be, with any transfer taxes payable in connection with the sale of the Securities duly paid by the Company. The global notes will be made available for inspection by the Representatives at the offices of Davis Polk and Wardwell set forth above not later than 1:00 P.M., New York City time, on the Business Day prior to the Closing Date or the Additional Closing Date, as the case may be, or at such other time and place as agreed in writing by the Representatives and the Company.

     (h) The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither the Representatives nor any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters

relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

     5. Conditions of Underwriters’ Obligations. The obligation of each Underwriter to purchase the Firm Securities on the Closing Date or the Option Securities on the Additional Closing Date, as the case may be as provided herein is subject to the performance by the Company of its covenants and other obligations hereunder and to the following additional conditions:

     (a) Registration Compliance; No Stop Order. No stop order suspending the effectiveness of the Registration Statement shall be in effect, and no proceeding for such purpose, pursuant to Rule 401(g)(2) or pursuant to Section 8A under the Securities Act shall be pending before or threatened by the Commission; the Prospectus and each Issuer Free Writing Prospectus shall have been timely filed with the Commission under the Securities Act (in the case of an Issuer Free Writing Prospectus, to the extent required by Rule 433 under the Securities Act) and in accordance with Section 5(a) hereof; and all requests by the Commission for additional information shall have been complied with to the reasonable satisfaction of the Representatives.

     (d) No Material Adverse Change. No event or condition of a type described in Section 1(a)(viii) hereof shall have occurred or shall exist, which event or condition is not described in the Time of Sale Information (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 or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

     (e) Officer’s Certificate. The Representatives shall have received on and as of the Closing Date or the Additional Closing Date, as the case may be, 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, to the knowledge of such officers, the representations set forth in Sections 1(a)(i), 1(a)(ii), 1(a)(v), and 1(a)(vi) 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 such Closing Date and (iii) to the effect set forth in paragraphs (c) above.

     (f) Comfort Letters. On the date of this Agreement and on the Closing Date or the Additional Closing Date, as the case may be, Ernst and Young LLP shall have furnished to the Representatives, at the request of the Company, letters, dated the respective dates of delivery thereof and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representatives, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus; provided, that the letter delivered on the Closing Date or the Additional Closing Date, as the case may be shall use a “cut-off” date no more than three business days prior to such Closing Date or such Additional Closing Date, as the case may be.

     (k) No Legal Impediment to Issuance. No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority that would, as of the Closing Date or the Additional Closing Date, as the case may be, prevent the issuance or sale of the Securities; and no injunction or order of any federal, state or foreign court shall have been issued that would, as of the Closing Date or the Additional Closing Date, as the case may be, prevent the issuance or sale of the Securities.

     (l) Good Standing. The Representatives shall have received on and as of the Closing Date or the Additional Closing Date, as the case may be, satisfactory evidence of the good standing of the Company in their respective jurisdictions of organization and its good standing as foreign entities in such other jurisdictions as the Representatives may reasonably request, in each case in writing or any standard form of telecommunication from the appropriate Governmental Authorities of such jurisdictions.

     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 or any Time of Sale Information, 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 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 Time of Sale Information, 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 and reallowance figures appearing in the third paragraph under the caption “Underwriting”, the information contained in the eleventh and twelfth paragraphs and the third sentence of the thirteenth paragraph 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 this Section 6 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 this Section 6. 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 or (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person. It is understood and agreed 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 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 JPMorgan 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 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 admiss ion 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.

     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 or, in the case of the Option Securities, prior to the Additional 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 National Association of Securities Dealers, Inc., 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 or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

     9. Defaulting Underwriter. (a) If, on the Closing Date or the Additional Closing Date, as the case may be, 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 or the Additional Closing Date, as the case may be, 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 or the Additional Closing Date, as the case may be, 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 or the Additional Closing Date, as the case may be, 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 or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Securities on the Additional Closing Date, as the case may be, 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 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 Time of Sale Information 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 fees and expenses of the Company’s counsel and independent accountants; (v) the reasonable fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) the cost of preparing stock certificates; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the National Association of Securities Dealers, Inc.; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors. Except as otherwise provided herein, the Underwriters will pay all of their own costs and expenses in connection with the transactions contemplated hereby, including, without limitation, the fees and expenses of their counsel and transfer taxes, if any, on the resale of the Securities by them.

     (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 Section 5 of 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.

FOR IMMEDIATE RELEASE

Trinity Industries Prices $450 Million of Convertible Subordinated Notes

     DALLAS, TEXAS — June 1, 2006 — Trinity Industries, Inc. (NYSE: TRN) today announced that it has priced its previously announced offering of $450 million aggregate principal amount of Convertible Subordinated Notes due 2036 (the “notes”). The Company has granted the underwriters a 13-day option to purchase an additional $50 million of the notes.

          The notes will bear interest at a fixed rate equal to 3.875% per annum, payable semi-annually commencing December 1, 2006. In addition, commencing with the six-month period beginning June 1, 2018, and for each six-month period thereafter, Trinity Industries will pay contingent interest to holders of the notes under certain circumstances. The notes will be convertible upon occurrence of specified events. If converted, holders of the notes will receive cash up to the principal amount of a note and, if the market price of Trinity Industries common stock exceeds the conversion price in effect on the conversion date, holders will also receive, at the election of Trinity Industries, additional cash, a number of shares of Trinity Industries common stock or a combination of both. The notes have an initial conversion price of $78.34 per share of common stock, which is a premium of 35% over Trinity Industries’ closing stock price of $58.03 on June 1, 2006.

          Trinity Industries may redeem all or a portion of the notes for cash at any time on or after June 1, 2018, at a price equal to 100% of their principal amount, plus accrued and unpaid interest, including any contingent interest, up to but excluding the redemption date. On June 1, 2018, or upon the occurrence of a change in control, holders of the notes may require Trinity Industries to purchase all or a portion of their notes at a price equal to 100% of the principal amount of the notes submitted for repurchase, plus any accrued and unpaid interest, including any contingent interest, up to but excluding the repurchase date.

          Trinity Industries intends to use the proceeds of this offering to provide additional funds for general corporate purposes, including the expansion of its railcar leasing business and possible repayments or repurchases of a portion of its outstanding indebtedness.

          J. P. Morgan Securities Inc., Banc of America Securities LLC, and Wachovia Securities are acting as joint book-running managers.

          The issuer has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send to you the prospectus if you request it by calling toll-free ###-###-#### or you may e-mail a request to ***@***, ***@***, or ***@***.

Trinity reports five principal business segments: the Rail Group, the Railcar Leasing and Management Services Group, the Inland Barge Group, the Construction Products Group, and the Energy Equipment Group.

Re: Trinity Industries, Inc. -— Public Offering

Ladies and Gentlemen:

     The undersigned understands that you, as Representatives of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Trinity Industries, Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule I to the Underwriting Agreement (the “Underwriters”), of 3 7/8% Convertible Subordinated Notes, of the Company (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

     In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, the undersigned will not, during the period ending 45 days after the date of the prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock, $1.00 per share par value, of the Company (the “Common Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period ending 45 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. Notwithstanding the foregoing, if (1) during the last 17 days of the 45-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company becomes publicly available; or (2) prior to the expiration of the 45-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 45-day period, the restrictions imposed by this Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. Notwithstanding anything to the contrary in this Letter Agreement, the undersigned, together with the other persons signing this form of Letter Agreement, shall be permitted during such restricted period to sell (or transfer economic rights in whole or in part to, or grant any right, warrant or option with respect to), in aggregate, 1,000,000 shares of Common Stock (subject to adjustment for stock splits, dividends, combinations of shares or similar transactions and provided that any shares covered by or transferred pursuant to the immediately following paragraph shall not be counted towards such 1,000,000 share exception).

     The restrictions set forth in the immediately preceding paragraph shall not apply to (a) bona fide gifts to charitable or nonprofit institutions, (b) dispositions by will or under the laws of intestacy, (c) dispositions to the immediate family of the undersigned, (d) dispositions to any trust, partnership or limited liability company for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, (e) dispositions to a spouse, former spouse, child or other dependent pursuant to a domestic relations order or an order of a court of competent jurisdiction or (f) dispositions to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (a) through (e) above; provided that (i) the transferee agrees in writing with the Underwriters to be bound by the terms of this Letter Agreement, and (ii) in the case of clauses (b), (c), (d), (e) or (f), no filing by any party (either transferor or transferee) under Section 16(a) of the Securities Exchange Act of 1934, as amended, shall be required or shall be made voluntarily in connection with such transfer or disposition (other than a filing on a Form 5 made after the expiration of the 45-day restricted period). For purposes of this Letter Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition,

notwithstanding the immediately preceding paragraph, if the undersigned is a corporation, partnership or limited liability company, the corporation, partnership or limited liability company may transfer the undersigned’s shares of Common Stock to any entity that is an affiliate (as such term is defined under Rule 405 of the Securities Act of 1933, as amended) of such corporation, partnership or limited liability company, provided that (i) any such transferee agrees in writing with the Underwriters to be bound by the terms of this Letter Agreement, and (ii) no filing by any party (either transferor or transferee) under Section 16(a) of the Securities Exchange Act of 1924, as amended, shall be required or shall be made voluntarily in connection with such transfer or disposition (other than a filing on a Form 5 made after the expiration of the 45-day restricted period). Further, the restrictions set forth in the immediately preceding paragraph shall not apply to (i) the receipt, exercise, cashless exercise (whether to cover exercise price or taxes), vesting or forfeiture of, or removal or lapse of restrictions on, any stock option, common stock issued upon exercise of a stock option, restricted stock or other award pursuant to any existing employee benefit plan or agreement and (ii) any purchases of Common Stock pursuant to elections directing the investment of additional funds under the Company’s 401(k) plan.

     In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

     The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

     The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, the undersigned shall be released form all obligations under this Letter Agreement. The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.

     This Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

Company prior to the Closing Date (other than (i) the financial statements and related notes and schedules contained or incorporated by reference therein and (ii) any statistical or financial data or information contained or incorporated by reference therein, as to which such counsel need express no opinion) 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 (B) that the Time of Sale Information, as of the Applicable Time (other than (i) the financial statements and related notes and schedules contained or incorporated by reference therein and (ii) any statistical or financial data or information contained or incorporated by reference therein, as to which such counsel need express no opinion) contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (C) that, as of its date, the Prospectus or any further amendment or supplement thereto made by the Company prior to the Closing Date (other than (i) the financial statements and related notes and schedules contained or incorporated by reference therein and (ii) any statistical or financial data or information contained or incorporated by reference therein, as to which such counsel need express no opinion) contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or that, as of the Closing Date, the Prospectus or any further amendment or supplement thereto made by the Company prior to the Closing Date (other than (i) the financial statements and related notes and schedules contained or incorporated by reference therein and (ii) any Tax Matters, statistical or financial data or information contained or incorporated by reference therein, as to which such counsel need express no opinion) contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Exhibit C

[Form of Opinion of Strasburger & Price, LLC]

     We have acted as counsel to Trinity Industries, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing of a registration statement (Registration No. 333-134596) on Form S-3 (the “Registration Statement”), including a form of prospectus (the “Prospectus”), for the purpose of registering under the Securities Act of 1933, as amended (the “Securities Act”), the sale from time to time of (i) up to $500,000,000.00 aggregate principal amount of the Company’s convertible subordinate Securities due June 1, 2036 (the “Securities”) and (ii) such indeterminate number of shares of the Company’s common stock, par value $1.00 per share, as may be issuable upon conversion of the Securities. This opinion and consent is being furnished in accordance with the requirements of Item 601(b)(8) and 601(b)(23) of Regulation S-K of the Securities Act.

     In delivering this opinion letter, we have reviewed and relied upon: the Registration Statement and Prospectus. We have also examined, and have relied upon as to matters of fact, in addition to the documents referred to above, originals, or duplicates or certified or conformed copies, of such corporate records, agreements, documents and other instruments and certificates or comparable documents, and we have made such other investigations, as we have deemed relevant and necessary in connection with the opinion hereinafter set forth. In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies, and the authenticity of the originals of such latter documents.

     Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein and in the Registration Statement, we are of the opinion that the statements set forth in the Registration Statement under the caption “Material United States federal income tax considerations,” [and certain other sections relating to tax analysis] to the extent they constitute summaries of matters of United States federal tax law and regulations or legal conclusions with respect thereto, fairly summarize the matters described therein in all material respects.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to us under the heading “Material United States federal income tax consequences” in the Prospectus. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.

Exhibit D

[Form of Opinion of S. Theis Rice, Vice President and Chief Legal Officer of the Company]
