A. Representations and Warranties of the Company and the Principal --------------------------------------------------------------- Selling Stockholders. The Company and the Principal Selling Stockholders - -------------------- represent and warrant to, and agree with, the Underwriters that: (a) The Company has filed with the Securities and Exchange Commission (the "Commission") in accordance with the provisions of the Securities Act of 1933, as amended (the "Act"), and the rules and regulations of the Commission thereunder (the "Regulations") a registration statement, and may have filed an amendment or amendments thereto, on Form S-1 (No. 333-74441) for the registration of the Shares under the Act. The registration statement contains two prospectuses to be used in connection with the offering and sale of the Shares: the U.S. prospectus, to be used in connection with the offering and sale of Shares in the United States and Canada to United States and Canadian Persons, and the international prospectus, to be used in connection with the offering and sale of Shares outside the United States and Canada to persons other than United States and Canadian Persons. The international prospectus is identical to the U.S. prospectus except for the outside front and back cover pages and the section captioned "Material U.S. Tax Considerations to Non-U.S. Holders of the Common Stock" (which appears only in the international prospectus) and certain cross-references relating thereto. All of the Shares have been duly registered under the Act pursuant to the initial registration statement, or if an abbreviated registration statement has been, or is proposed to be, filed pursuant to Rule 462(b) of the Regulations (the "Rule 462(b) Registration Statement"), all of the Shares have been or will be, on the date of this Agreement, duly registered under the Act pursuant to the initial registration statement and the Rule 462(b) Registration Statement. Such registration statement, including the U.S. prospectus and the International prospectus, financial statements and schedules, exhibits and all other documents filed as a part thereof, as amended at the time of effectiveness of the registration statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A or Rule 434 of the Regulations is herein called the "Registration Statement" and the U.S. prospectus and the International prospectus, in the respective forms first filed with the Commission pursuant to Rule 424(b) of the Regulations or filed as part of the Registration Statement at the time of effectiveness if no Rule 434 or Rule 424(b) filing is required, are hereinafter collectively referred to as the "Prospectus". If the Company has filed or proposes to file a Rule 462 Registration Statement, then any reference herein to the term "Registration Statement" shall include such Rule 462 Registration Statement. The term "preliminary prospectus" as used herein means a 2 preliminary prospectus as described in Rule 430 of the Regulations. All references in this Agreement to (i) the Registration Statement, the Rule 462(b) Registration Statement, a preliminary prospectus, the Prospectus or a term sheet that complies with Rule 434, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System ("EDGAR") and (ii) the Prospectus shall be deemed to include the "electronic Prospectus" provided for use in connection with the offering of the Shares as contemplated by Section 4(g) of this Agreement. (b) Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Act and, if filed by electronic transmission pursuant to EDGAR (except as may be permitted by Regulation S-T under the Act), was identical to the copy thereof delivered to the Underwriters for use in connection with the offer and sale of the Shares. Each of the Registration Statement, any Rule 462(b) Registration Statement and any post-effective amendment thereto, at the time it became effective and at all subsequent times, complied or will comply in all material respects with the applicable provisions of the Act and the Regulations and does not or will not contain an untrue statement of a material fact and does not or will not omit to state any material fact required to be stated therein or necessary in order to make the statements therein (i) in the case of the Registration Statement, not misleading and (ii) in the case of the Prospectus, in light of the circumstances under which they were made, not misleading. When any related preliminary prospectus was first filed with the Commission (whether filed as part of the registration statement for the registration of the Shares or any amendment thereto or pursuant to Rule 424(a) of the Regulations) and when any amendment thereof or supplement thereto was first filed with the Commission, such preliminary prospectus and any amendments thereof and supplements thereto complied in all material respects with the applicable provisions of the Act and the Regulations and did not contain an untrue statement of a material fact and did not omit to state any material fact required to be stated therein or necessary in order to make the statements therein in light of the circumstances under which they were made not misleading. No representation and warranty is made in this subsection (b), however, with respect to any information contained in or omitted from the Registration Statement or the Prospectus or any related preliminary prospectus or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through you as herein stated expressly for use in connection with the preparation thereof.

Each of the Company and its subsidiaries has all requisite power and authority, and all material consents, approvals, authorizations, orders, registrations, qualifications, licenses and permits of and from all public, regulatory or governmental agencies and bodies, which are necessary to own, lease and operate its properties and conduct the business of the Company and its subsidiaries, taken as a whole, as now being conducted and as described in the Registration Statement and the Prospectus, and no such consent, approval, authorization, order, registration, qualification, license or permit contains a materially burdensome restriction not adequately disclosed in the Registration Statement and the Prospectus.

Payment shall be made to the Company and the Selling Stockholders, (or the Custodian named in the Custody Agreement on behalf of the Selling Stockholders), by wire transfer of immediately available funds, against delivery to you for the respective accounts of the Underwriters of certificates for the Firm Shares to be purchased by them.

The Company will permit you to examine and package such certificates for delivery at least one full business day prior to the Closing Date. If you so elect, delivery of the Firm Shares purchased from the Company may be made by credit through full fast transfer to the accounts at The Depository Trust Company designated by you.

The Company will permit you to examine and package such certificates for delivery at least one full business day prior to the Additional Closing Date.

(b) If at any time when a prospectus relating to the Shares is required to be delivered under the Act any event shall have occurred as a result of which the Prospectus as then amended or supplemented would, in the judgment of the Underwriters or the Company, include 12 an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary at any time to amend or supplement the Prospectus or Registration Statement to comply with the Act or the Regulations, the Company will notify you promptly and prepare and file with the Commission an appropriate amendment or supplement (in form and substance satisfactory to you) which will correct such statement or omission and will use its best efforts to have any amendment to the Registration Statement declared effective as soon as possible. (c) The Company will promptly deliver to you two conformed copies of the Registration Statement, including exhibits and all amendments thereto, and will maintain in the Company's files manually signed copies of such documents for at least five years from the date of filing.

The Company will promptly advise you of the receipt by the Company of any notification with respect to suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose and will use every reasonable effort to obtain the withdrawal of any order of suspension as soon as possible.

Such electronic Prospectus may consist of a Rule 434 preliminary prospectus, together with the applicable term sheet, provided that it otherwise satisfies the format and conditions described in the immediately preceding sentence.

Each of the Company and its subsidiaries is duly qualified and in good standing as a foreign corporation in each jurisdiction in which the character or location of its properties (owned, leased or licensed) or the nature or conduct of its business makes such qualification necessary, except for those failures to be so qualified or in good standing which will not in the aggregate have a material adverse effect on the Company and its subsidiaries taken as a whole. Each of the Company and its subsidiaries has all requisite corporate authority to own, lease and license its respective properties and conduct its business as now being conducted and as described in the Registration Statement and the Prospectus. All of the issued and outstanding capital stock of each subsidiary of the Company has been duly and validly issued and is fully paid and nonassessable and was not issued in violation of preemptive rights and, is owned directly or indirectly by the Company, free and clear of any lien, encumbrance, claim, security interest, restriction on transfer, shareholders' agreement, voting trust or other defect of title whatsoever.

(v) To such counsel's knowledge, all agreements, instruments, franchises, licenses or permits required to be described in the Registration Statement and the Prospectus or required to be filed as exhibits to the Registration Statements have been so described and so filed. (vi) The execution, delivery, and performance of this Agreement and the consummation of the transactions contemplated hereby by the Company do not and will not (A) to such counsel's knowledge result in a material breach of any of the terms and provisions of, or constitute a default (or an event which with notice or lapse of time, 17 or both, would constitute a default) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its subsidiaries pursuant to, any agreement, instrument, franchise, license or permit known to such counsel to which the Company or any of its subsidiaries is a party or by which any of such corporations or their respective properties or assets may be bound or (B) violate or conflict with any provision of the certificate of incorporation or by-laws of the Company or any of its subsidiaries, or, to the best knowledge of such counsel, any judgment, decree, order, statute, rule or regulation of any court or any public, governmental or regulatory agency or body having jurisdiction over the Company or any of its subsidiaries or any of their respective properties or assets.

(b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the Company, each Principal Selling Stockholder, each Other Selling Stockholder, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Shares, as originally filed or any amendment thereof, or any related preliminary prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through you expressly for use therein; provided, however, that in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discount applicable to the Shares purchased by such Underwriter hereunder. This indemnity will be in addition to any liability which any Underwriter may otherwise have including under this Agreement. The Company and each Principal Selling Stockholder acknowledges that the statements set forth in the last paragraph of the cover page and under the caption "Underwriting" in the Prospectus constitute the only information furnished in writing by or on behalf of any Underwriter expressly for use in the registration statement relating to the Shares as originally filed or in any amendment thereof, any related preliminary prospectus or the Prospectus or in any amendment thereof or supplement thereto, as the case may be. (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 7). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party. Notwithstanding 23 the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. Anything in this subsection to the contrary notwithstanding, an indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent; provided, however, that such consent was not unreasonably withheld. 8. Contribution. In order to provide for contribution in circumstances ------------ in which the indemnification provided for in Section 7 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company, each Selling Stockholder and the Underwriters shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, claims, damages, liabilities and expenses suffered by the Company and the Selling Stockholders any contribution received by the Company and the Selling Stockholders from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company) as incurred to which the Company and one or more of the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company, each Selling Stockholder and the Underwriters from the offering of the Shares or, if such allocation is not permitted by applicable law or indemnification is not available as a result of the indemnifying party not having received notice as provided in Section 7 hereof, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company, each Selling Stockholder and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as (x) the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company or each Selling Stockholder and (y) the underwriting discounts and commissions received by the Underwriters, respectively, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company, each Selling Stockholder and of the Underwriters 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 any Selling Stockholder or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, each Selling Stockholder and the 24 Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 8, (i) in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discount applicable to the Shares purchased by such Underwriter hereunder, and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Notwithstanding the provisions of this Section 8 and the preceding sentence, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public 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. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to clauses (i) and (ii) of this Section 8 The liability of each Selling Stockholder under the indemnity and reimbursement agreements contained in the provisions of this Section 8 and Section 17 hereof shall be limited to an amount equal to the net proceeds of the Shares sold by such Selling Stockholder to the Underwriters. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise. No party shall be liable for contribution with respect to any action or claim settled without its consent; provided, however, that such consent was not unreasonably withheld. 9. Default by an Underwriter. ------------------------- (a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Firm Shares or Additional Shares hereunder, and if the Firm Shares or Additional Shares with respect to which such default relates do not (after giving effect to arrangements, if any, made by you pursuant to subsection (b) below) exceed in the aggregate 10% of the number of Firm Shares or Additional Shares, to which the default relates shall be purchased by the non-defaulting Underwriters in proportion to the respective proportions which the numbers of Firm Shares set forth opposite their respective names in Schedule I and Schedule II hereto bear to the aggregate number of Firm Shares set forth opposite the names of the non- defaulting Underwriters. 25 (b) In the event that such default relates to more than 10% of the Firm Shares or Additional Shares, as the case may be, you may in your discretion arrange for yourself or for another party or parties (including any non- defaulting Underwriter or Underwriters who so agree) to purchase such Firm Shares or Additional Shares, as the case may be, to which such default relates on the terms contained herein. In the event that within 5 calendar days after such a default you do not arrange for the purchase of the Firm Shares or Additional Shares, as the case may be, to which such default relates as provided in this Section 9, this Agreement or, in the case of a default with respect to the Additional Shares, the obligations of the Underwriters to purchase and of the Company to sell the Additional Shares shall thereupon terminate, without liability on the part of the Company with respect thereto (except in each case as provided in Section 5, 7(a) and 8 hereof) or the Underwriters, but nothing in this Agreement shall relieve a defaulting Underwriter or Underwriters of its or their liability, if any, to the other Underwriters and the Company for damages occasioned by its or their default hereunder. (c) In the event that the Firm Shares or Additional Shares to which the default relates are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, you or the Company shall have the right to postpone the Closing Date or Additional Closing Date, as the case may be, for a period, not exceeding five business days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment or supplement to the Registration Statement or the Prospectus which, in the opinion of Underwriters' Counsel, may thereby be made necessary or advisable. The term "Underwriter" as used in this Agreement shall include any party substituted under this Section 9 with like effect as if it had originally been a party to this Agreement with respect to such Firm Shares and Additional Shares. 10. Survival of Representations and Agreements. All representations ------------------------------------------ and warranties, covenants and agreements of the Underwriters and the Company contained in this Agreement, including the agreements contained in Section 5, the indemnity agreements contained in Section 7 and the contribution agreements contained in Section 8, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof or by or on behalf of the Company, any of its officers and directors or any controlling person thereof, and shall survive delivery of and payment for the Shares to and by the Underwriters. The representations contained in Section 1 and the agreements contained in Sections 5, 7, 8 and 11(d) hereof shall survive the termination of this Agreement, including termination pursuant to Section 9 or 11 hereof. 11. Effective Date of Agreement; Termination. ---------------------------------------- (a) This Agreement shall become effective, upon the later of when (i) you and the Company shall have received notification of the effectiveness of the Registration Statement or (ii) the execution of this Agreement. If either the initial public offering price or the purchase price per Share has not been agreed upon prior to 5:00 P.M., New York time, on the fifth full business day after the Registration Statement shall have become effective, this Agreement shall thereupon terminate without liability to the Company or the Underwriters except as herein expressly provided. Until this Agreement becomes effective as aforesaid, it may be terminated by the Company by notifying you or by you notifying the Company. Notwithstanding the 26 foregoing, the provisions of this Section 11 and of Sections 1, 5, 7 and 8 hereof shall at all times be in full force and effect. (b) You shall have the right to terminate this Agreement at any time prior to the Closing Date or the obligations of the Underwriters to purchase the Additional Shares at any time prior to the Additional Closing Date, as the case may be, if (A) any domestic or international event or act or occurrence has materially disrupted, or in your reasonable opinion will in the immediate future materially disrupt, the market for the Company's securities or securities in general; or (B) if trading on the New York or American Stock Exchanges or on Nasdaq shall have been suspended, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the New York or American Stock Exchanges or on Nasdaq by the New York or American Stock Exchanges or Nasdaq or by order of the Commission or any other governmental authority having jurisdiction; or (C) if a banking moratorium has been declared by a state or federal authority or if any new restriction materially adversely affecting the distribution of the Firm Shares or the Additional Shares, as the case may be, shall have become effective; or (D) (i) if the United States becomes engaged in hostilities or there is an escalation of hostilities involving the United States or there is a declaration of a national emergency or war by the United States or (ii) if there shall have been such change in political, financial or economic conditions if the effect of any such event in (i) or (ii) as in your judgment makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Firm Shares or the Additional Shares, as the case may be, on the terms contemplated by the Prospectus. (c) Any notice of termination pursuant to this Section 11 shall be by telephone, telex, or telegraph, confirmed in writing by letter. (d) If this Agreement shall be terminated pursuant to any of the provisions hereof (otherwise than pursuant to (i) notification by you as provided in Section 11(a) hereof or (ii) Section 9(b) or 11(b) hereof), or if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by you, reimburse the Underwriters for all out-of-pocket expenses (including the fees and expenses of their counsel), incurred by the Underwriters in connection herewith. 12.

Headings. The headings of the sections of this Agreement have -------- been inserted for convenience of reference only and shall not be deemed a part of this Agreement. 17. Reimbursement of Underwriters' Expenses. If this Agreement is --------------------------------------- terminated by the Representatives pursuant to Section 6, Section 9, Section 11, or Section 18, or if the sale to the Underwriters of the Shares on the Closing Date is not consummated because of any refusal, inability or failure on the part of the Company or the Selling Stockholders to perform any agreement herein or to comply with any provision hereof, the Company agrees to reimburse the Representatives and the other Underwriters (or such Underwriters as have terminated this Agreement with respect to themselves), severally, upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the Representatives and the Underwriters in connection with the proposed purchase and the offering and sale of the Shares, including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges provided however, that (i) to the extent such payment is ultimately held to be improper, the persons receiving such payments shall promptly refund them and (ii) such persons shall provide to the Company, upon request, reasonable assurances of their ability to effect any refund, when and if due. 18. Failure of One or More of the Selling Stockholders to Sell and -------------------------------------------------------------- Deliver Common Shares. If one or more of the Selling Stockholders shall fail - --------------------- to sell and deliver to the Underwriters the Shares to be sold and delivered by such Selling Stockholders at the Closing Date pursuant to this Agreement, the Company hereby agrees to sell and deliver to the Underwriters that number of Shares equal to the number of Shares not sold and delivered by such Selling Stockholders. Furthermore, if one or more of the Selling Stockholders shall fail to sell and deliver to the Underwriters in the aggregate more than two hundred thousand (200,000) of the Shares then the Underwriters may at their option, by written notice from the Representatives to the Company and the Selling Stockholders, terminate this Agreement without any liability on the part of any Underwriter or, except as provided in Sections 5, 7 and 17 hereof, the Company or the Selling Stockholders.
