                  1. Representations and Warranties of the Company and the
Selling Stockholders. (a) The Company represents and warrants to, and agrees
with, each Underwriter that:

                         (i) The Company meets the requirements for use of Form
                    S-3 under the Act and has prepared and filed with the
                    Commission a registration statement (File No. 333-112354) on
                    Form S-3, including a related Basic Prospectus, for
                    registration under the Act of the offering and sale of the
                    Securities. The Company may have filed one or more
                    amendments thereto, including a Preliminary Prospectus, each
                    of which has previously been furnished to you. The Company
                    will next file with the Commission one of the following: (1)
                    after the Effective Date of such registration statement, a
                    final prospectus supplement relating to the Securities in
                    accordance with Rules 430A and 424(b), (2) prior to the
                    Effective Date of such registration statement, an amendment
                    to such registration statement (including the form of final
                    prospectus supplement) or (3) a final prospectus in
                    accordance with Rules 415 and 424(b). In the case of clause
                    (1), the Company has included in such registration
                    statement, as amended at the Effective Date, all information
                    (other than Rule 430A Information) required by the Act and
                    the rules thereunder to be included in such registration
                    statement and the Final Prospectus. As filed, such final
                    prospectus supplement or such amendment and form of final
                    prospectus supplement shall contain all Rule 430A
                    Information, together with all other such required
                    information, and, except to the extent the Representatives
                    shall agree in writing to a modification, shall be in all
                    substantive respects in the form furnished to you prior to
                    the Execution Time or, to the extent not completed at the
                    Execution Time, shall contain only such specific additional
                    information and other changes (beyond that contained in the
                    Basic Prospectus and any Preliminary Prospectus) as the
                    Company has advised you, prior to the Execution Time, will
                    be included or made therein. The Registration Statement, at
                    the Execution Time, meets the requirements set forth in Rule
                    415(a)(1)(x).
                                       2


                         (ii) On the Effective Date, the Registration Statement
                    did or will, and when the Final Prospectus is first filed
                    (if required) in accordance with Rule 424(b) and on the
                    Closing Date (as defined herein) the Final Prospectus (and
                    any supplement thereto) will, comply in all material
                    respects with the applicable requirements of the Act and the
                    rules thereunder; the Incorporated Documents, when they were
                    filed, complied in all material respects with the applicable
                    requirements of the Exchange Act and the rules thereunder;
                    on the Effective Date and at the Execution Time, the
                    Registration Statement did not or will not contain 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 not misleading; and, on
                    the Effective Date, the Final Prospectus, if not filed
                    pursuant to Rule 424(b), will not, and on the date of any
                    filing pursuant to Rule 424(b) and on the Closing Date, the
                    Final Prospectus (together with any supplement thereto) 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, not misleading; provided, however,
                    that the Company makes no representations or warranties as
                    to the information contained in or omitted from the
                    Registration Statement, or the Final Prospectus (or any
                    supplement thereto) in reliance upon and in conformity with
                    information furnished in writing to the Company by or on
                    behalf of any Selling Stockholder or Underwriter through the
                    Representatives specifically for inclusion in the
                    Registration Statement or the Final Prospectus (or any
                    supplement thereto), it being understood and agreed that the
                    only such information is that described as such in Sections
                    8(b) and 8(c) hereof, respectively.

                         (iii) Each of the Company and its subsidiaries (other
                    than Sovereign Marine & General Insurance Company Limited
                    and its subsidiaries) has been duly organized and is validly
                    existing and in good standing under the laws of the
                    jurisdiction in which it is organized with requisite power
                    and authority to own or lease, as the case may be, and to
                    operate its properties and conduct its business as described
                    in the Final Prospectus, and is duly qualified to do
                    business and is in good standing under the laws of each
                    jurisdiction which requires such qualification, except where
                    the failure to be so qualified would not, individually or in
                    the aggregate, reasonably be expected to have a material
                    adverse effect on the condition (financial or otherwise),
                    business or results of operations of the Company and its
                    subsidiaries, taken as a whole (a "Material Adverse
                    Effect").

                         (iv) All the outstanding common equity interests in
                    each of the Company's subsidiaries have been duly authorized
                    and validly issued and are fully paid and nonassessable,
                    and, except as otherwise set forth on Schedule III, all
                    outstanding common equity interests in each such subsidiary
                    are owned by the Company either directly or indirectly and,
                    except as set forth in the Final Prospectus, are owned free
                    and clear of any perfected security interest or any other
                    security interests, claims, liens or encumbrances.

                    any statute, judgment, decree, order, rule or regulation
                    applicable to the Company or its Subsidiaries or any of
                    their properties or assets or (iii) in breach or default in
                    the performance of any Contract, except, in the case of
                    clauses (i), (ii) and (iii) (and in the case of clause (i),
                    only with respect to the Subsidiaries) for any such
                    violation, breach or default that would not, individually or
                    in the aggregate, reasonably be expected to have a Material
                    Adverse Effect.

                         (xv) No stamp duty, stock exchange tax, value-added
                    tax, withholding or any other similar duty or tax is payable
                    in the United States, the United Kingdom, Bermuda or any
                    other jurisdiction in which either the Company or any of its
                    subsidiaries is organized or engaged in business for tax
                    purposes or, in each case, any political subdivision thereof
                    or any authority having power to tax, in connection with the
                    execution or delivery of this Agreement by the Company or
                    the sale or delivery of the Securities by the Selling

                    this Agreement and the Final Prospectus.

                         (xvi) Each of the Company and its subsidiaries has
                    filed all necessary federal, state and foreign (including,

                    franchise tax returns required to be filed to the date
                    hereof, except where the failure to so file such returns
                    would not, individually or in the aggregate, reasonably be
                    expected to have a Material Adverse Effect, and has paid all
                    material taxes shown as due thereon; and other than tax
                    deficiencies which the Company or any subsidiary is
                    contesting in good faith and for which the Company or such
                    subsidiary has provided adequate reserves, there is no tax
                    deficiency that has been asserted against the Company or any
                    of the subsidiaries that would reasonably be expected to
                    have, individually or in the aggregate, a Material Adverse
                    Effect.

                         (xvii) Each of the Company and its subsidiaries has

                    it and good title to all leasehold estates in the real
                    property described in the Final Prospectus as being leased
                    by it except for (i) liens for taxes not yet due and
                    payable, (ii) liens and encumbrances that are contemplated
                    by the Senior Credit Facility, (iii) liens, claims,
                    encumbrances and restrictions that do not materially
                    interfere with the use made and proposed to be made of such
                    properties (including, without limitation, purchase money
                    mortgages), and (iv) to the extent the failure to have such
                    title or the existence of such liens, claims, encumbrances
                    and restrictions would not reasonably be expected to have a
                    Material Adverse Effect.

                                       6


                         (xviii) Neither the Company nor any of its subsidiaries
                    is involved in any labor dispute nor, to the best of the
                    knowledge of the Company and its subsidiaries, is any labor
                    dispute threatened which, if such dispute were to occur,
                    would reasonably be expected to have a Material Adverse
                    Effect.

                         (xix) The Company and each of its subsidiaries maintain
                    insurance insuring against such losses and risks as the
                    Company reasonably believes is adequate to protect the
                    Company and each of its subsidiaries and their respective
                    businesses, except where the failure to maintain such
                    insurance would not reasonably be expected to have a
                    Material Adverse Effect; the Company and its subsidiaries
                    are in compliance with the terms of such policies and
                    instruments in all material respects; and there are no
                    claims by the Company or any of its subsidiaries under any
                    such policy or instrument as to which any insurance company
                    is denying liability or defending under a reservation of
                    rights clause that would reasonably be expected to have a
                    Material Adverse Effect; none of the Company or its
                    subsidiaries has been refused any insurance coverage sought
                    or applied for; and neither the Company nor any such
                    subsidiary has any reason to believe that it will not be
                    able to renew its existing insurance coverage as and when
                    such coverage expires or to obtain similar coverage from
                    similar insurers as may be necessary to continue its
                    business at a cost that would not reasonably be expected to
                    have a Material Adverse Effect whether or not arising from
                    transactions in the ordinary course of business, except as
                    set forth in the Final Prospectus (exclusive of any
                    supplement thereto).

                         (xx) Under the current laws and regulations of Bermuda,
                    all dividends and other distributions declared and payable
                    on the Securities may be paid by the Company to the holder
                    thereof in United States dollars that may be freely
                    transferred out of Bermuda and all such payments made to
                    holders thereof who are non-residents of Bermuda will not be
                    subject to income, withholding or other taxes under the laws
                    or regulations of Bermuda and will otherwise be free of any
                    other tax, duty, withholding or deduction in Bermuda and
                    without the necessity of obtaining any governmental
                    authorization in Bermuda.

                         (xxi) Each of the Company and its subsidiaries
                    possesses all licenses, permits, certificates, consents,
                    orders, approvals and other authorizations from, and has
                    made all declarations and filings with, all appropriate
                    federal, state, local, foreign and other governmental
                    authorities, all self-regulatory organizations and all
                    courts and other tribunals, presently required or necessary
                    to own or lease, as the case may be, and to operate their
                    respective properties and to carry on the business of the
                    Company and its subsidiaries as now conducted as set forth
                    in the Final Prospectus, the lack of which would,
                    individually or in the aggregate, reasonably be expected to
                    have a Material Adverse Effect ("Permits"); each of the
                    Company and its subsidiaries has fulfilled and performed all
                    of its obligations with respect to such Permits and, to the
                    best knowledge of the Company, no event has occurred which
                    allows, or after notice or lapse of time would allow,
                    revocation or termination thereof or results in any other
                    impairment of the rights of the holder of any such Permit,
                    except where the failure to fulfill or perform such
                    obligations or such impairment, would not, individually or
                    in the aggregate, reasonably be expected to have a Material
                    Adverse Effect; and none of the Company or its subsidiaries
                    has received any notice of any proceeding relating to
                    revocation or modification of any such Permit except where
                    such revocation or modification would not, individually or
                    in the aggregate, reasonably be expected to have a Material
                    Adverse Effect.

                                       7


                         (xxii) Each of the Company and its subsidiaries
                    maintain a system of internal control over financial
                    reporting sufficient to provide reasonable assurance that
                    (i) the Company's financial records, in reasonable detail,
                    accurately and fairly reflect the transactions and
                    dispositions of the assets of the Company; (ii) transactions
                    are recorded as necessary to permit preparation of financial
                    statements in accordance with generally accepted accounting
                    principles, and that receipts and expenditures of the
                    Company are being made only in accordance with
                    authorizations of management and directors of the Company;
                    and (iii) unauthorized acquisition, use or disposition of
                    the Company's assets that could have a material effect on
                    the Company's financial statements are detected in a timely
                    manner. The Company maintains disclosure controls and
                    procedures (as such term is defined in Rule 13a-15 under the
                    Exchange Act) that are effective in ensuring that
                    information required to be disclosed by the Company in the
                    reports that it files or submits under the Exchange Act is
                    recorded, processed, summarized and reported, within the
                    time periods specified in the rules and forms of the
                    Commission, including, without limitation, controls and
                    procedures designed to ensure that information required to
                    be disclosed by the Company in the reports that it files or
                    submits under the Exchange Act is accumulated and
                    communicated to the Company's management, including its
                    principal executive officer or officers and its principal
                    financial officer or officers, as appropriate to allow
                    timely decisions regarding required disclosure.

                         (xxiii) There is and has been no failure on the part of
                    the Company and any of the Company's directors or officers,
                    in their capacities as such, to comply with any provision of
                    the Sarbanes Oxley Act of 2002 and the rules and regulations
                    promulgated in connection therewith (the "Sarbanes Oxley
                    Act"), including Section 402 related to loans and Sections
                    302 and 906 related to certifications.

                         (xxiv) The Company has not taken, directly or
                    indirectly, any action designed to or that would constitute
                    or that might reasonably be expected to cause or result in,
                    under the Exchange Act or otherwise, stabilization or
                    manipulation of the price of any security of the Company to
                    facilitate the sale or resale of the Securities.

                         (xxv) Except as would not, individually or in the
                    aggregate, reasonably be expected to have a Material Adverse
                    Effect, to the knowledge of the Company and its
                    subsidiaries, the Company and its subsidiaries are in
                    compliance with all applicable existing federal, state,
                    local and foreign laws and regulations relating to the
                    protection of human health or the environment or imposing
                    liability or requiring standards of conduct concerning any
                    Hazardous Materials ("Environmental Laws"). The term
                    "Hazardous Material" means (a) any "hazardous substance" as
                    defined by the Comprehensive Environmental Response,
                    Compensation and Liability Act of 1980, as amended, (b) any

                    product, (d) any polychlorinated biphenyl and (e) any
                    pollutant or contaminant or hazardous, dangerous or toxic
                    chemical, material, waste or substance regulated under or
                    within the meaning of any other Environmental Law. None of
                    the Company or its subsidiaries has received any written
                    notice and there is no pending or, to the best knowledge of
                    the Company and its subsidiaries, threatened action, suit or
                    proceeding before or by any court or governmental agency or
                    body alleging liability (including, without limitation,
                    alleged or potential liability for investigatory costs,
                    cleanup costs, governmental response costs, natural
                    resources damages, property damages, personal injuries, or
                    penalties) of the Company or any of its subsidiaries arising
                    out of, based on or resulting from (i) the presence or
                    release into the environment of any Hazardous Material at
                    any location owned by the Company or any subsidiary of the
                    Company, or (ii) any violation or alleged violation of any
                    Environmental Law, in either case (x) which alleged or
                    potential liability would be required to be described in the
                    Registration Statement under the Act, or (y) which alleged
                    or potential liability would, individually or in the
                    aggregate, reasonably be expected to have a Material Adverse
                    Effect.

                                        8


                         (xxvi) None of the Company or its subsidiaries has any
                    material liability for any prohibited transaction or funding
                    deficiency or any complete or partial withdrawal liability
                    with respect to any pension, profit sharing or other plan
                    which is subject to the Employee Retirement Income Security
                    Act of 1974, as amended ("ERISA"), to which it makes or ever
                    has made a contribution and in which any employee of it is
                    or has ever been a participant. With respect to such plans,
                    each of the Company and its subsidiaries is in compliance in
                    all material respects with all applicable provisions of
                    ERISA. In addition, the Company has caused (i) all pension
                    schemes maintained by or for the benefit of any of its
                    subsidiaries organized under the laws of England and Wales
                    or any of its employees to be maintained and operated in all
                    material respects in accordance with all applicable laws
                    from time to time and (ii) all such pension schemes to be
                    funded in accordance with the governing provisions of such
                    schemes, except to the extent failure to do so would not,
                    individually or in the aggregate, reasonably be expected to
                    have a Material Adverse Effect.

                         (xxvii) The subsidiaries listed on Schedule IV attached
                    hereto are the only significant subsidiaries of the Company
                    as defined by Rule 1-02 of Regulation S-X (the
                    "Subsidiaries").

                         (xxviii) The Company and each of its subsidiaries own
                    or possess adequate licenses or other rights to use all
                    patents, patent applications, trademarks, service marks,
                    trade names, trademark registrations, service mark
                    registrations, copyrights, licenses and know-how (including,
                    without limitation, trade secrets and other unpatented
                    and/or unpatentable proprietary or confidential information,
                    systems or procedures) and copyrights necessary to conduct
                    the business described in the Final Prospectus, except where
                    the failure to own or possess or have the ability to acquire
                    any of the foregoing would not, individually or in the
                    aggregate, reasonably be expected to have a Material Adverse
                    Effect, and none of the Company or its subsidiaries has
                    received any notice of infringement of or conflict with
                    asserted rights of others with respect to any patents,
                    trademarks, service marks, trade names or copyrights which,
                    if such assertion of infringement or conflict were
                    sustained, would individually or in the aggregate,

                    necessary in order to make the statements therein not

                         (i) The Company will use its best efforts to cause the
                    Registration Statement, if not effective at the Execution
                    Time, and any amendment thereof, to become effective. Prior

                    Statement or supplement (including the Final Prospectus or
                    any Preliminary Prospectus) to the Basic Prospectus or any
                    Rule 462(b) Registration Statement unless the Company has
                    furnished you a copy for your review prior to filing and
                    will not file any such proposed amendment or supplement to
                    which you reasonably object. Subject to the foregoing
                    sentence, if the Registration Statement has become or
                    becomes effective pursuant to Rule 430A, or filing of the
                    Final Prospectus is otherwise required under Rule 424(b),
                    the Company will cause the Final Prospectus, properly
                    completed, and any supplement thereto to be filed with the
                    Commission pursuant to the applicable paragraph of Rule
                    424(b) within the time period prescribed. The Company will
                    promptly advise the Representatives (1) when the
                    Registration Statement, if not effective at the Execution
                    Time, shall have become effective, (2) when the Final
                    Prospectus, and any supplement thereto, shall have been
                    filed (if required) with the Commission pursuant to Rule
                    424(b) or when any Rule 462(b) Registration Statement shall
                    have been filed with the Commission, (3) when, prior to
                    termination of the offering of the Securities, any amendment
                    to the Registration Statement shall have been filed or
                    become effective, (4) of any request by the Commission or
                    its staff for any amendment of the Registration Statement,
                    or any Rule 462(b) Registration Statement, or for any
                    supplement to the Final Prospectus or for any additional
                    information, (5) of the issuance by the Commission of any
                    stop order suspending the effectiveness of the Registration
                    Statement or the institution or threatening of any
                    proceeding for that purpose and (6) of the receipt by the
                    Company of any notification with respect to the suspension
                    of the qualification of the Securities for sale in any
                    jurisdiction or the institution or threatening of any
                    proceeding for such purpose. The Company will use its best
                    efforts to prevent the issuance of any such stop order or
                    the suspension of any such qualification and, if issued, to
                    obtain as soon as possible the withdrawal thereof.

                         (ii) If, at any time when a prospectus relating to the
                    Securities is required to be delivered under the Act, any
                    event occurs as a result of which the Final Prospectus as
                    then supplemented would include any untrue statement of a
                    material fact or omit to state any material fact 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 to amend the Registration Statement
                    or supplement the Final Prospectus to comply with the Act or
                    the Exchange Act or the respective rules thereunder, the
                    Company will (1) promptly notify the Representatives of any
                    such event, (2) as soon as practicable, prepare and file
                    with the Commission, subject to the second sentence of

                    financial statements made available by the Company and its
                    subsidiaries; their limited review, in accordance with
                    standards established under Statement on Auditing Standards
                    No. 100, of the unaudited interim financial information for
                    the three-month period ended March 31, 2005, the six-month
                    period ended June 30, 2005 and the nine-month period ended
                    September 30, 2005; carrying out certain specified
                    procedures (but not an examination in accordance with
                    generally accepted auditing standards) which would not
                    necessarily reveal matters of significance with respect to
                    the comments set forth in such letter; a reading of the
                    minutes of the meetings of the stockholders, directors and
                    the executive, finance, compensation and audit committees of
                    the Company and the Subsidiaries; and inquiries of certain
                    officials of the Company who have responsibility for
                    financial and accounting matters of the Company and its
                    subsidiaries as to transactions and events subsequent to
                    September 30, 2005:


                                       19


                                  (1) nothing came to their attention which
                    caused them to believe that any unaudited financial
                    statements included or incorporated by reference in the
                    Registration Statement and the Final Prospectus do not
                    comply as to form in all material respects with applicable
                    accounting requirements of the Act and with the related
                    rules and regulations adopted by the Commission with respect
                    to registration statements on Form S-3; and said unaudited
                    financial statements are not in conformity with generally
                    accepted accounting principles applied on a basis
                    substantially consistent with that of the audited financial
                    statements included in the Registration Statement and the
                    Final Prospectus;

                                  (2) with respect to the period subsequent
                    to September 30, 2005, nothing came to their attention which
                    caused them to believe that there were any changes, at a
                    specified date not more than five days prior to the date of
                    the letter, in the total long-term debt of the Company and
                    its subsidiaries or capital stock of the Company or
                    decreases in the consolidated net assets of the Company or
                    in the total stockholders' equity of the Company as compared
                    with the amounts shown on the September 30, 2005
                    consolidated balance sheet included in the Registration
                    Statement and the Final Prospectus, or for the period from
                    October 1, 2005 to such specified date, there were any
                    decreases, as compared with the corresponding period in the
                    preceding year, in total revenues, net income, operating
                    income or basic and diluted net earnings per share, except
                    in all instances for changes or decreases set forth in such
                    letter, in which case the letter shall be accompanied by an
                    explanation by the Company as to the significance thereof
                    unless said explanation is not deemed necessary by the
                    Representatives;

                                  (3) nothing came to their attention which
                    caused them to believe that the information included or
                    incorporated by reference in the Registration Statement and
                    Final Prospectus in response to Regulation S-K, Item 301
                    (Selected Financial Data), Item 302 (Supplementary Financial
                    Information), Item 402 (Executive Compensation) and Item
                    503(d) (Ratio of Earnings to Fixed Charges) is not in
                    conformity with the applicable disclosure requirements of
                    Regulation S-K; and


                                       20


                         (iii) they have performed certain other specified
                    procedures as a result of which they determined that certain
                    information of an accounting, financial or statistical
                    nature (which is limited to accounting, financial or
                    statistical information derived from the general accounting
                    records of the Company and its subsidiaries) set forth in
                    the Registration Statement and the Final Prospectus that has
                    previously been identified to you agrees with the accounting
                    records of the Company and its subsidiaries, excluding any
                    questions of legal interpretation.

                  References to the Final Prospectus in this paragraph (k)
include any supplement thereto at the date of the letter.

                                  (l) Subsequent to the Execution Time or,
                    if earlier, the dates as of which information is given in
                    the Registration Statement (exclusive of any amendment
                    thereof) and the Final Prospectus (exclusive of any
                    supplement thereto), there shall not have been (i) any
                    change or decrease specified in the letter or letters
                    referred to in paragraph (k) of this Section 6 or (ii) any
                    change, or any development that can be expected to have a
                    material adverse effect on the condition (financial or
                    otherwise), business or results of operations of the Company
                    and its subsidiaries taken as a whole, whether or not
                    arising from transactions in the ordinary course of
                    business, except as set forth in the Final Prospectus
                    (exclusive of any supplement thereto) the effect of which,
                    in any case referred to in clause (i) or (ii) above, is, in
                    the judgment of the Representatives, so material and adverse
                    as to make it impractical or inadvisable to proceed with the
                    offering or delivery of the Securities as contemplated by
                    the Registration Statement (exclusive of any amendment
                    thereof) and the Final Prospectus (exclusive of any
                    supplement thereto).

               (m) Prior to the Closing Date, the Company and the Selling
          Stockholders shall have furnished to the Representatives such further
          customary information, certificates and documents as the
          Representatives may reasonably request.

               (n) Subsequent to the Execution Time, there shall not have been
          any decrease in the rating of debt securities of the Company or any of
          its subsidiaries by any "nationally recognized statistical rating
          organization" (as defined for purposes of Rule 436(g) under the Act)
          or any notice given of any intended or potential decrease in any such
          rating or of a possible change in any such rating that does not
          indicate the direction of the possible change.


                                       21


               (o) The Company shall have furnished to the Representatives, in
          each case effective as of the Execution Time, a letter substantially
          in the form of Exhibit A hereto and addressed to the Representatives
          from each person listed on Schedule V.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancelation shall be given to the Company and
the Selling Stockholders in writing or by telephone or facsimile confirmed in
writing.

                  The documents required to be delivered by this Section 6 shall
be delivered at the office of Cravath, Swaine & Moore LLP, counsel for the
Underwriters, at Worldwide Plaza, 825 Eighth Avenue, New York, New York,
10019-7475 on the Closing Date.

                  7. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied
because of any refusal, inability or failure on the part of the Company or any
Selling Stockholder to perform any agreement herein or comply with any provision
hereof other than by reason of a default by any of the Underwriters, the Company
will reimburse the Underwriters severally through Citigroup Global Markets Inc.
on demand accompanied by reasonable supporting documentation for all reasonable
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
that shall have been incurred by them in connection with the proposed purchase
and sale of the Securities. If the Company is required to make any payments to
the Underwriters under this Section 7 because of any Selling Stockholder's
refusal, inability or failure to satisfy any condition to the obligations of the
Underwriters set forth in Section 6, such Selling Stockholder shall reimburse
the Company on demand for all amounts so paid.

                  8. Indemnification and Contribution. (a) The Company agrees
to indemnify and hold harmless each Underwriter, the directors, officers,
employees and agents of each Underwriter and each person who controls any
Underwriter within the meaning of either the Act or the Exchange Act against any
and all losses, claims, damages or liabilities, joint or several, to which they
or any of them may become subject under the Act, the Exchange Act or other
foreign, federal, state or statutory law or regulation, at common law or
otherwise, insofar as such losses, claims, damages or liabilities (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 Securities as originally filed or in any amendment
thereof, or in the Basic Prospectus, any Preliminary Prospectus or the Final
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, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon 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 the Representatives specifically for inclusion therein,
it being understood and agreed that the only such information is that described
in Section 8(c) hereof; provided, further, that with respect to any untrue
statement or omission of material fact made in any Preliminary Prospectus, the
indemnity agreement contained in this Section 8(a) shall not inure to the
benefit of any Underwriter from whom the person asserting any such loss, claim,
damage or liability purchased the Securities concerned, to the extent that any
such loss, claim, damage or liability of such Underwriter occurs under the
circumstance where it shall be determined by a court of competent jurisdiction
by final and non-appealable judgment that (i) the Company had previously
furnished copies of the Final Prospectus to the Representatives, (ii) the untrue
statement or omission of a material fact contained in the Preliminary Prospectus
was corrected in the Final Prospectus and (iii) such loss, claim, damage or
liability results from the fact that there was not sent or given to such person
at or prior to the written confirmation of the sale of such Securities to such
person, a copy of the Final Prospectus. This indemnity agreement will be in
addition to any liability which the Company may otherwise have.

                                       22


                  (b) Each Selling Stockholder severally and not jointly
agrees to indemnify and hold harmless the Company, each of its directors, each
of its officers who signs the Registration Statement, each Underwriter, the
directors, officers, employees and agents of each Underwriter and each person
who controls the Company or any Underwriter within the meaning of either the Act
or the Exchange Act and each other Selling Stockholder, if any, to the same
extent as the foregoing indemnity from the Company to each Underwriter, but only
with reference to written information furnished to the Company by or on behalf
of such Selling Stockholder specifically for inclusion in the documents referred
to in the foregoing indemnity; and such indemnity will be limited to an amount
equal to the aggregate gross proceeds, net of the underwriting discounts,
received by such Selling Stockholder from the sale of the Securities to the
Underwriters. This indemnity agreement will be in addition to any liability
which any Selling Stockholder may otherwise have. Each Underwriter acknowledges
that the name of each Selling Stockholder and the number of securities each
Selling Stockholder is offering constitute the only information furnished in
writing by or on behalf of each of the Selling Stockholders for inclusion in any
Preliminary Prospectus or the Final Prospectus.

                  (c) Each Underwriter severally and not jointly agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers who signs the Registration Statement, and each person who controls the
Company within the meaning of either the Act or the Exchange Act and each
Selling Stockholder, to the same extent as the foregoing indemnity from the
Company to each Underwriter, but only with reference to written information
relating to such Underwriter furnished to the Company by or on behalf of such
Underwriter through the Representatives specifically for inclusion in the
documents referred to in the foregoing indemnity. This indemnity agreement will
be in addition to any liability which any Underwriter may otherwise have. The
Company and each Selling Stockholder acknowledge that the statements set forth
in the last paragraph of the cover page regarding delivery of the Securities
and, under the heading "Underwriting", (i) the list of Underwriters and their
respective participation in the sale of the Securities, (ii) the third
paragraph, (iii) the ninth, tenth and eleventh paragraphs related to
stabilization, syndicate covering transactions and penalty bids in any
Preliminary Prospectus and (iv) the fourteenth paragraph relating to electronic
prospectuses, constitute the only information furnished in writing by or on
behalf of the several Underwriters for inclusion in any Preliminary Prospectus
or the Final Prospectus.

                                       23


                  (d) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a), (b) or (c) above unless
and to the extent it did not otherwise learn of such action and such failure
results in the forfeiture by the indemnifying party of substantial rights and
defenses and (ii) will not, in any event, relieve the indemnifying party from
any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a), (b) or (c) above. The indemnifying party
shall be entitled to appoint counsel of the indemnifying party's choice at the
indemnifying party's expense to represent the indemnified party in any action
for which indemnification is sought (in which case the indemnifying party shall
not thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be reasonably satisfactory to the
indemnified party. Notwithstanding the indemnifying party's election to appoint
counsel to represent the indemnified party in an action, the indemnified party
shall have the right to employ separate counsel (including local counsel), and
the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
the indemnified party to represent the indemnified party within a reasonable
time after notice of the institution of such action or (iv) the indemnifying
party shall authorize the indemnified party to employ separate counsel at the
expense of the indemnifying party. An indemnifying party will not, without the
prior written consent of the indemnified parties (which consent shall not be
unreasonably withheld), settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

                                       24





                  (e) In the event that the indemnity provided in paragraph (a),
(b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless
an indemnified party for any reason, the Company, each of the Selling
Stockholders and the Underwriters agree to contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending same) (collectively
"Losses") to which the Company, each of the Selling Stockholders and one or more
of the Underwriters may be subject in such proportion as is appropriate to
reflect the relative benefits received by the Company, by each of the Selling
Stockholders and by the Underwriters from the offering of the Securities;
provided, however, that in no case shall (i) any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting discount
or commission applicable to the Securities purchased by such Underwriter
hereunder. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company, each of the Selling Stockholders and
the Underwriters shall contribute in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company, of each of the Selling Stockholders and of the Underwriters in
connection with the statements or omissions which resulted in such Losses as
well as any other relevant equitable considerations. Benefits received by the
Company and/or by each of the Selling Stockholders shall be deemed to be equal
to the total net proceeds from the offering (before deducting expenses) received
by such Selling Stockholder, and benefits received by the Underwriters shall be
deemed to be equal to the total underwriting discounts and commissions, in each
case as set forth on the cover page of the Final Prospectus. Relative fault
shall be determined by reference to, among other things, whether any untrue or
any alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information provided by the
Company, such Selling Stockholder or the Underwriters, the intent of the parties
and their relative knowledge, access to information and opportunity to correct
or prevent such untrue statement or omission. The Company, each of the Selling
Stockholders and the Underwriters agree that it would not be just and equitable
if contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (e), 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. For purposes of this Section 8, each person who
controls an Underwriter within the meaning of either the Act or the Exchange Act
and each director, officer, employee and agent of an Underwriter shall have the
same rights to contribution as such Underwriter, and each person who controls
the Company within the meaning of either the Act or 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 the applicable terms and conditions of this
paragraph (e).



                                       25


                  (f) The liability of each Selling Stockholder under such
Selling Stockholder's representations and warranties contained in Section 1
hereof and under the indemnity and contribution agreements contained in this
Section 8 shall be limited to an amount equal to the aggregate gross proceeds,
net of underwriting discounts, received by such Selling Stockholder from the
sale of the Securities to the Underwriters. The Company and the Selling
Stockholders may agree, as among themselves and without limiting the rights of
the Underwriters under this Agreement, as to the respective amounts of such
liability for which they each shall be responsible.

                  (g) The Company agrees to indemnify and hold harmless each
Underwriter, the directors, officers, employees and agents of each Underwriter
and each person who controls any Underwriter within the meaning of either the
Act or the Exchange Act against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any failure or alleged failure by the
Company to comply with the terms of the Consortium Registration Rights
Agreement, the Profit Sharing Registration Rights Agreement or the Management
Registration Rights Agreement in connection with the transactions contemplated
by this Agreement.

                  9. Default by an Underwriter. If any one or more
Underwriters shall fail to purchase and pay for any of the Securities agreed to
be purchased by such Underwriter or Underwriters hereunder and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Underwriters shall be obligated
severally to take up and pay for (in the respective proportions which the amount
of Securities set forth opposite their names in Schedule I hereto bears to the
aggregate amount of Securities set forth opposite the names of all the remaining
Underwriters) the Securities which the defaulting Underwriter or Underwriters
agreed but failed to purchase; provided, however, that in the event that the
aggregate amount of Securities which the defaulting Underwriter or Underwriters
agreed but failed to purchase shall exceed 10% of the aggregate amount of
Securities set forth in Schedule I hereto, the remaining Underwriters shall have
the right to purchase all, but shall not be under any obligation to purchase
any, of the Securities, and if such non-defaulting Underwriters do not purchase
all the Securities, this Agreement will terminate without liability to any
non-defaulting Underwriter, the Selling Stockholders or the Company. In the
event of a default by any Underwriter as set forth in this Section 9, the
Closing Date shall be postponed for such period, not exceeding five Business
Days, as the Representatives shall determine in order that the required changes
in the Registration Statement and the Final Prospectus or in any other documents
or arrangements may be effected. Nothing contained in this Agreement shall
relieve any defaulting Underwriter of its liability, if any, to the Company, the
Selling Stockholders and any non-defaulting Underwriter for damages occasioned
by its default hereunder.

                    10. Termination. This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to the Company and the Selling Stockholders prior to delivery of and payment for
the Securities, if (a) at any time subsequent to the execution and delivery of
this Agreement and prior to such time (i) trading in the Company's Common Stock
shall have been suspended by the Commission or the New York Stock Exchange or
trading in securities generally on the New York Stock Exchange shall have been
suspended or limited or minimum prices shall have been established on such
Exchange, (ii) a banking moratorium shall have been declared either by Federal
or New York State authorities or (iii) there shall have occurred any outbreak or
escalation of hostilities, declaration by the United States or the United
Kingdom of a national emergency or war, or other calamity or crisis that is
material and adverse and (b) in the case of any of the events specified in
clauses 10(a)(i) through 10(a)(iii), the effect of such event, singly or
together with any other such event, makes it, in the judgment of the
Representatives, impractical or inadvisable to proceed with the offering or
delivery of the Securities as contemplated by the Final Prospectus (exclusive of
any supplement thereto).

                                       26


                  11. Representations and Indemnities to Survive. The
respective agreements, representations, warranties, indemnities and other
statements of the Company or its officers, of each Selling Stockholder and of
the Underwriters set forth in or made pursuant to this Agreement will remain in
