                  1. Representations and Warranties. The Company represents and
warrants to, and agrees with, each Underwriter as set forth below in this
Section 1.

                  (a) 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 number 333-[________], 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 Final 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 Final 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).

                  (b) 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 in
         Section 3 below) and on any date on which Option Securities are
         purchased, if such date is not the Closing Date (a "settlement date"),
         the Final Prospectus (and any supplements thereto) will, comply in all
         material respects with the applicable requirements of the Act and the
         Exchange Act and the respective 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 and any settlement 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

         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

         business as a foreign corporation and is in good standing under the
         laws of each jurisdiction which requires such qualification and where

         the condition (financial or otherwise), prospects, earnings, business
         or properties of the Company and its subsidiaries, taken as a whole (a
         "Material Adverse Effect").

         subsidiaries are owned by the Company either directly or through wholly
         owned subsidiaries free and clear of any perfected security interest or
         any other security interests, claims, liens or encumbrances.

         the holders of outstanding shares of capital stock of the Company are
         not entitled to preemptive or other rights to subscribe for the
         Securities; and, except as set forth in the Final Prospectus, no
         options, warrants or other rights to purchase, agreements or other
         obligations to issue, or rights to convert any obligations into or
         exchange any securities for, shares of capital stock of or ownership
         interests in the Company are outstanding.

         as amended.

                  (i) No consent, approval, authorization, filing with or order
         of any court or governmental agency or body is required in connection
         with the transactions contemplated herein, except such as have been

         laws of any jurisdiction in connection with the purchase and
         distribution of the Securities by the Underwriters in the manner
         contemplated herein and in the Final Prospectus.

                  (j) Neither the issue and sale of the Securities nor the
         consummation of any other of the transactions contemplated herein nor
         the fulfillment of the terms hereof will conflict with, result in a

         pursuant to, (i) the charter or by-laws of the Company or any of its
         subsidiaries, (ii) the terms of any indenture, contract, lease,
         mortgage, deed of trust, note agreement, loan agreement or other
         agreement, obligation, condition, covenant or instrument to which the
         Company or any of its subsidiaries is a party or bound or to which its
         or their property is subject, or (iii) any statute, law, rule,
         regulation, judgment, order or decree applicable to the Company or any
         of its subsidiaries of any court, regulatory body, administrative
         agency, governmental body, arbitrator or other authority having
         jurisdiction over the Company or any of its subsidiaries or any of its
         or their properties.

                  (k) No holders of securities of the Company have rights to the
         registration of such securities under the Registration Statement.

                  (l) The consolidated historical financial statements and
         schedules of the Company and its consolidated subsidiaries included in

         threatened that (i) could reasonably be expected to have a material
         adverse effect on the performance of this Agreement or the consummation
         of any of the transactions contemplated hereby or (ii) could 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 or contemplated in the Final Prospectus (exclusive of any
         supplement thereto).

   5

                  (m) No action, suit or proceeding by or before any court or
         governmental agency, authority or body or any arbitrator involving the
         Company or any of its subsidiaries or its or their property is pending
         or, to the best knowledge of the Company, threatened that (i) could
         reasonably be expected to have a Material Adverse Effect on the
         performance of this Agreement or the consummation of any of the
         transactions contemplated hereby or (ii) could 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
         or contemplated in the Final Prospectus (exclusive of any supplement
         thereto).

                  (n) Each of the Company and each of its subsidiaries owns or

         of any indenture, contract, lease, mortgage, deed of trust, note
         agreement, loan agreement or other agreement, obligation, condition,
         covenant or instrument to which it is a party or bound or to which its
         property is subject, or (iii) except where any such violation or
         default could not reasonably be expected, individually or in the
         aggregate, to have a Material Adverse Effect, any statute, law, rule,
         regulation, judgment, order or decree of any court, regulatory body,
         administrative agency, governmental body, arbitrator or other authority
         having jurisdiction over the Company or such subsidiary or any of its
         properties, as applicable.

                  (p) PricewaterhouseCoopers LLP, who have certified certain
         financial statements of the Company and its consolidated subsidiaries
         and delivered their report with respect to the audited consolidated
         financial statements and schedules included or incorporated by
         reference in the Final Prospectus, are independent public accountants
         with respect to the Company within the meaning of the Act and the
         applicable published rules and regulations thereunder.

                  (q) The Company has filed all foreign, federal, state and
         local tax returns that are required to be filed or has requested
         extensions thereof (except in any case in which the failure so to file
         would not have a Material Adverse Effect, whether or not arising from
         transactions in the ordinary course of business, except as set forth in
         or contemplated in the Final Prospectus (exclusive of any supplement
         thereto) and has paid all taxes required to be paid by it and any other
         assessment, fine or penalty levied against it, to the extent that any
         of the foregoing is due and payable, except for any such assessment,
         fine or penalty that is currently being contested in good faith or as
         would not have a Material Adverse Effect, whether or not arising from
         transactions in the ordinary course of business, except as set forth in
         or contemplated in the Final Prospectus (exclusive of any supplement
         thereto).

                  (r) The Company and each of its subsidiaries maintain a system
         of internal accounting controls sufficient to provide reasonable
         assurance that (i) transactions are executed in accordance with
         management's general or specific authorizations; (ii) transactions are
         recorded as necessary to permit preparation of financial statements in
         conformity with generally accepted accounting principles and to
         maintain asset

   6

         accountability; (iii) access to assets is permitted only in accordance
         with management's general or specific authorization; and (iv) the
         recorded accountability for assets is compared with the existing assets
         at reasonable intervals and appropriate action is taken with respect to
         any differences.

                  (s) No loss experience has occurred since December 31, 1999
         which would require or make it necessary or appropriate for the Company
         to change, alter, modify or amend the Company's methodology or
         assumptions relating to losses.

                  (t) Each of the Insurance Subsidiaries holds all licenses,
         certificates and permits from insurance departments and other
         governmental authorities ("Insurance Licenses") necessary to conduct
         its business as presently conducted, except where the failure to hold
         any such Insurance Licenses would not have a Material Adverse Effect.
         Each of the Insurance Subsidiaries has fulfilled and performed all
         material obligations necessary to maintain its Insurance Licenses, and
         no event or events have occurred which would result in the impairment,
         modification, termination or revocation of such Insurance Licenses,
         except where such impairment, modification, termination or revocation
         would not have a Material Adverse Effect.

                  Any certificate signed by any officer of the Company and
delivered to the Representatives or counsel for the Underwriters in connection
with the offering of the Securities shall be deemed a representation and
warranty by the Company, as to matters covered thereby, to each Underwriter.

                  2. Purchase and Sale. (a) Subject to the terms and
conditions and in reliance upon the representations and warranties set forth
herein, the Company agrees to sell to each Underwriter, and each Underwriter
agrees, severally and not jointly, to purchase from the Company, at $[____] per
share, the number of shares of the Underwritten Securities set forth opposite
such Underwriter's name in Schedule I hereto.

                  (b) Subject to the terms and conditions and in reliance upon
the representations and warranties set forth herein, the Company hereby grants
an option to the several Underwriters to purchase, severally and not jointly,
the Option Securities at the same purchase price per share as the Underwritten
Securities. Said option may be exercised only to cover over-allotments in the
sale of the Underwritten Securities by the Underwriters. Said option may be
exercised in whole or in part at any time (but not more than once) on or before
the 30th day after the date of the Final Prospectus upon written or telegraphic
notice by the Representatives to the Company setting forth the number of shares
of the Option Securities as to which the several Underwriters are exercising the
option and the settlement date. The number of shares of Option Securities to be
purchased by each Underwriter shall be the same percentage of the total number
of shares of the Option Securities to be purchased by the several Underwriters
as such Underwriter is purchasing of the Underwritten Securities, subject to
such adjustments as you in your absolute discretion shall make to eliminate any
fractional shares.

                  3. Delivery and Payment. Delivery of and payment for the
Underwritten Securities and the Option Securities (if the option provided for in
Section 2(b) hereof shall have been exercised on or before the third Business
Day prior to the Closing Date) shall be made on

   7

[_________________] at 10:00 a.m. New York City time or at such time on such
later date not more than three Business Days after the foregoing date as the
Representatives shall designate, which date and time may be postponed by
agreement between the Representatives and the Company or as provided in Section
9 hereof (such date and time of delivery and payment for the Securities being
called herein the "Closing Date"). Delivery of the Securities shall be made to
the Representatives for the respective accounts of the several Underwriters
against payment by the several Underwriters through the Representatives of the
purchase price thereof to or upon the order of the Company by wire transfer
payable in same-day funds to an account specified by the Company. Delivery of
the Underwritten Securities and the Option Securities shall be made through the
facilities of The Depository Trust Company unless the Representatives shall
otherwise instruct.

                  If the option provided for in Section 2(b) hereof is exercised
after the third Business Day prior to the Closing Date, the Company will deliver
the Option Securities (at the expense of the Company) to the Representatives, at
[______________________], on the date specified by the Representatives (which
shall be within three Business Days after exercise of said option) for the
respective accounts of the several Underwriters, against payment by the several
Underwriters through the Representatives of the purchase price thereof to or
upon the order of the Company by wire transfer payable in same-day funds to an
account specified by the Company. If settlement for the Option Securities occurs
after the Closing Date, the Company will deliver to the Representatives on the
settlement date for the Option Securities, and the obligation of the
Underwriters to purchase the Option Securities shall be conditioned upon receipt
of, supplemental opinions, certificates and letters confirming as of such date
the opinions, certificates and letters delivered on the Closing Date pursuant to
Section 6 hereof.

                  4. Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Final Prospectus.

                  5. Agreements. The Company agrees with the several
Underwriters that:

                  (a) 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 to the termination of the
         offering of the Securities, the Company will not file any amendment of
         the Registration Statement or supplement (including the Final
         Prospectus or any Preliminary Final 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
         and will provide evidence satisfactory to the Representatives of such
         timely filing. 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

   8

         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.

                  (b) 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 promptly will (1) notify the
         Representatives of any such event, (2) prepare and file with the
         Commission, subject to the second sentence of paragraph (a) of this
         Section 5, an amendment or supplement which will correct such statement
         or omission or effect such compliance and (3) supply any supplemented
         Final Prospectus to you in such quantities as you may reasonably
         request.

                  (c) As soon as practicable, the Company will make generally
         available to its security holders and to the Representatives an
         earnings statement or statements of the Company and its subsidiaries
         which will satisfy the provisions of Section 11(a) of the Act and Rule
         158 under the Act.

                  (d) The Company will furnish to the Representatives and
         counsel for the Underwriters, without charge, signed copies of the
         Registration Statement (including exhibits thereto) and to each other
         Underwriter a copy of the Registration Statement (without exhibits
         thereto) and, so long as delivery of a prospectus by an Underwriter or
         dealer may be required by the Act, as many copies of each Preliminary
         Final Prospectus and the Final Prospectus and any supplement thereto as
         the Representatives may reasonably request. The Company will pay the
         expenses of printing or other production of all documents relating to
         the offering.

                  (e) The Company will arrange, if necessary, for the
         qualification of the Securities for sale under the laws of such
         jurisdictions as the Representatives may designate, will maintain such
         qualifications in effect so long as required for the distribution of
         the Securities and will pay any fee of the National Association of
         Securities Dealers, Inc., in connection with its review of the
         offering, if required; provided, that in no event shall the Company be
         obligated to qualify to do business in any jurisdiction where it is not
         now so qualified or to take any action that would subject it to

   9

         service of process in suits, other than those arising out of the
         offering or sale of the Securities, in any jurisdiction where it is not
         now so subject.

                  (f) The Company will not, without the prior written consent of
         Salomon Smith Barney Inc., offer, sell, contract to sell, pledge, or
         otherwise dispose of (or enter into any transaction which is designed
         to, or might reasonably be expected to, result in the disposition
         (whether by actual disposition or effective economic disposition due to
         cash settlement or otherwise) by the Company or any affiliate of the
         Company or any person in privity with the Company or any affiliate of
         the Company), directly or indirectly, including the filing (or
         participation in the filing) of a registration statement with the
         Commission in respect of, or establish or increase a put equivalent
         position or liquidate or decrease a call equivalent position within the
         meaning of Section 16 of the Exchange Act, any shares of Common Stock
         (other than the Securities) or any securities convertible into, or
         exercisable or exchangeable for, shares of Common Stock, or publicly
         announce an intention to effect any such transaction, for a period of
         90 days after the date of the Final Prospectus, provided, however, that
         the Company may (i) issue and sell Common Stock pursuant to any
         employee stock option plan, stock ownership plan or dividend
         reinvestment plan of the Company in effect at the Execution Time and
         (ii) issue Common Stock issuable upon the conversion of securities or
         the exercise of warrants or options outstanding at the Execution Time.

                  (g) The Company will not take, directly or indirectly, any
         action that constitutes or that is designed to or 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.

                  (h) The Company has furnished or will furnish to the
         Representatives "lock-up" letters substantially in the form of Exhibit
         A hereto, signed by each of its current officers and directors,
         pursuant to which each such person shall agree not to offer, sell,
         contract to sell or otherwise dispose of any Common Stock (or any
         securities convertible into or exercisable or exchangeable for Common
         Stock) or grant any options or warrants to purchase Common Stock for a
         period of 90 days after the date of the Final Prospectus without the
         prior written consent of [__________________].

                  6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Underwritten Securities and the
Option Securities, as the case may be, shall be subject to the accuracy of the
representations and warranties on the part of the Company contained herein as of

3 hereof, to the accuracy of the statements of the Company made in any
certificates pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder and to the following additional conditions:

                  (a) If the Registration Statement has not become
         effective prior to the Execution Time, unless the Representatives agree

         determination of the public offering price, if such determination
         occurred at or prior to 3:00 PM New York City time on such date or (ii)
         9:30 AM on the

   10

         Business Day following the day on which the public offering price was
         determined, if such determination occurred after 3:00 PM New York City
         time on such date; if filing of the Final Prospectus, or any supplement
         thereto, is required pursuant to Rule 424(b), the Final Prospectus, and

         period required by Rule 424(b); and no stop order suspending the
         effectiveness of the Registration Statement shall have been issued and

                  otherwise set forth in the Final Prospectus, all outstanding
                  shares of capital stock of the Subsidiaries are owned by the
                  Company either directly or through wholly owned subsidiaries
                  free and clear of any perfected security interest and, to the
                  knowledge of such counsel, after due inquiry, any other

   11

                  authority or body or any arbitrator involving the Company or
                  any of its subsidiaries or its or their property of a
                  character required to be disclosed in the Registration
                  Statement which is not adequately disclosed in the Final
                  Prospectus, and there is no franchise, contract or other
                  document of a character required to be described in the
                  Registration Statement or the Final Prospectus, or to be filed
                  as an exhibit thereto, which is not described or filed as
                  required.

                           (v) the Registration Statement has become effective

                  suspending the effectiveness of the Registration Statement has
                  been issued, no proceedings for that purpose have been
                  instituted or threatened, and the Registration Statement and
                  the Final Prospectus (other than the financial statements and
                  other financial information contained therein, as to which
                  such counsel need express no opinion) comply as to form in all
                  material respects with the applicable requirements of the Act
                  and the Exchange Act and the respective rules thereunder; and
                  such counsel has no reason to believe that on the Effective
                  Date or the date the Registration Statement was last deemed
                  amended the Registration Statement contained any untrue
                  statement of a material fact or omitted to state any material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading or that the Final Prospectus
                  as of its date and on the Closing Date included or includes
                  any untrue statement of a material fact or omitted 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 (in each case, other than the
                  financial statements and other financial information contained
                  therein, as to which such counsel need express no opinion);

                           (vi) this Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (vii) the Company is not and, after giving effect to
                  the offering and sale of the Securities and the application of
                  the proceeds thereof as described in the Final Prospectus,
                  will not be an "investment company" as defined in the
                  Investment Company Act of 1940, as amended;

                           (viii) no consent, approval, authorization, filing
                  with or order of any court or governmental agency or body is
                  required in connection with the transactions contemplated
                  herein, except such as have been obtained under the Act and
                  such as may be required under the blue sky laws of any
                  jurisdiction in connection with the purchase and distribution
                  of the Securities by the Underwriters in the manner
                  contemplated in this Agreement and in the Final Prospectus and
                  such other approvals (specified in such opinion) as have been
                  obtained;

                           (ix) neither the issue and sale of the Securities,
                  nor the consummation

   12

                  of any other of the transactions contemplated herein nor the
                  fulfillment of the terms hereof will conflict with, result in
                  a breach or violation of or imposition of any lien, charge or
                  encumbrance upon any property or assets of the Company or its
                  subsidiaries pursuant to, (i) the charter or by-laws of the
                  Company or its subsidiaries, (ii) the terms of any indenture,
                  contract, lease, mortgage, deed of trust, note agreement, loan
                  agreement or other agreement, obligation, condition, covenant
                  or instrument to which the Company or its subsidiaries is a
                  party or bound or to which its or their property is subject,
                  or (iii) any statute, law, rule, regulation, judgment, order
                  or decree applicable to the Company or its subsidiaries of any
                  court, regulatory body, administrative agency, governmental
                  body, arbitrator or other authority having jurisdiction over
                  the Company or its subsidiaries or any of its or their
                  properties; and

                           (x) no holders of securities of the Company have
                  rights to the registration of such securities under the
                  Registration Statement.

                  In rendering such opinion, such counsel may rely (A) as to
         matters involving the application of laws of any jurisdiction other
         than the State of Delaware or the Federal laws of the United States, to
         the extent they deem proper and specified in such opinion, upon the
         opinion of other counsel of good standing whom they believe to be
         reliable and who are satisfactory to counsel for the Underwriters and
         (B) as to matters of fact, to the extent they deem proper, on
         certificates of responsible officers of the Company and public
         officials. References to the Final Prospectus in this paragraph (b)
         include any supplements thereto at the Closing Date.

                  (c) The Representatives shall have received from
         [____________________], counsel for the Underwriters, such opinion or
         opinions, dated the Closing Date and addressed to the Representatives,
         with respect to the issuance and sale of the Securities, the
         Registration Statement, the Final Prospectus (together with any
         supplement thereto) and other related matters as the Representatives
         may reasonably require, and the Company shall have furnished to such
         counsel such documents as they request for the purpose of enabling them
         to pass upon such matters.

                  (e) The Company shall have furnished to the Representatives a
         certificate of the Company, signed by the Chairman of the Board or the
         President and the principal financial or accounting officer of the
         Company, dated the Closing Date, to the effect that the signers of such
         certificate have carefully examined the Registration Statement, the
         Final Prospectus, any supplements to the Final Prospectus and this
         Agreement and that:

                           (i) the representations and warranties of the Company
                  in this Agreement are true and correct on and as of the
                  Closing Date with the same effect as if made on the Closing
                  Date and the Company has complied with all the agreements and
                  satisfied all the conditions on its part to be performed or
                  satisfied at or prior to the Closing Date;

                           (ii) no stop order suspending the effectiveness of
                  the Registration Statement has been issued and no proceedings
                  for that purpose have been

   13

                  instituted or, to the Company's knowledge, threatened; and

                           (iii) since the date of the most recent financial
                  statements included or incorporated by reference in the Final
                  Prospectus (exclusive of any supplement thereto), there has
                  been no material adverse effect on the condition (financial or
                  otherwise), prospects, earnings, business or properties 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 or contemplated in the Final Prospectus
                  (exclusive of any supplement thereto).

                  (f) The Company shall have requested and caused
         PricewaterhouseCoopers LLP to have furnished to the Representatives, at
         the Execution Time and at the Closing Date, letters (which may refer to
         letters previously delivered to one or more of the Representatives),
         dated respectively as of the Execution Time and as of the Closing Date,
         in form and substance satisfactory to the Representatives, confirming
         that they are independent accountants within the meaning of the Act and
         the Exchange Act and the respective applicable rules and regulations
         adopted by the Commission thereunder and stating in effect, that:

                           (i) In their opinion the audited financial
                  statements and financial statement schedules included or
                  incorporated by reference in the Registration Statement and
                  the Final Prospectus and reported on by them comply as to form
                  in all material respects with the applicable accounting
                  requirements of the Act and the Exchange Act and the related
                  rules and regulations adopted by the Commission.

                           (ii) For purposes of these letters they have read
                  minutes of the meetings of the stockholders, the Board of
                  Directors of the Company and its subsidiaries as set forth in
                  the minute books at [____________], officials of the Company
                  having advised them that the minutes of all such meetings
                  through that date were set forth therein; and they have
                  carried out other procedures to [___________], as follows:

                           [extent of review--to come]

                           (iii) On the basis of the foregoing nothing came
                  to their attention which caused them to believe that:

                                    (1) any unaudited condensed consolidated
                           financial statements referred to in (ii)) above 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 financial statements
                           included or incorporated by reference in quarterly
                           reports on Form 10-Q under the Exchange Act; and said
                           unaudited financial statements are not in conformity
                           with generally accepted accounting principles


   14

                           applied on a basis substantially consistent with that
                           of the audited financial statements included or
                           incorporated by reference in the Registration
                           Statement and the Final Prospectus; or


                                    (2) 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) and Item 402 (Executive
                           Compensation) is not in conformity with the
                           applicable disclosure requirements of Regulation S-K.

                           (iv) 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 or incorporated by
                  reference in the Registration Statement and the Final
                  Prospectus agrees with the accounting records of the Company
                  and its subsidiaries, excluding any questions of legal
                  interpretation.

                  (g) 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 (e) of this Section 6 or (ii) any change, or any
         development involving a prospective change, in or affecting the
         condition (financial or otherwise), earnings, business or properties 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 or contemplated 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 sole 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).

                  (h) At the Execution Time, the Company shall have furnished to
         the Representatives a letter substantially in the form of Exhibit A
         hereto from each officer and director of the Company addressed to the
         Representatives.

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

                  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

   15

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 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 [_________________], counsel for the Underwriters,
at [____________________], 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 termination pursuant to Section 10 hereof 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 other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally through [________________] on demand for all 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.

                  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 Federal or
state 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 Final 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. This indemnity agreement will be in addition
to any liability which the Company may otherwise have.

                  (b) 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, to the same
extent as the indemnity from the Company to each Underwriter set forth in
paragraph (a) of this Section 8, 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

   16

indemnity. This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.

                  (c) 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) or (b) of this Section 8
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) or (b) of this Section 8.
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 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 (1) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (2) 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, (3) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (4) 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, 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.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters severally
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
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 on the one
hand and by the Underwriters on the other from the offering of the Securities;
provided, however, that in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities)

   17

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 and the Underwriters severally shall contribute in
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company on the one hand and of the Underwriters
on the other 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 shall be deemed to be equal to the total net proceeds
from the offering (before deducting expenses) received by it, 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 on the one hand or the
Underwriters on the other, 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 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 (d), 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 (d).

                  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 nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter 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


   18

of its liability, if any, to the Company and any nondefaulting 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 prior to delivery of and payment for the Securities, if at any
time 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 shall have been suspended or limited or minimum prices
shall have been established on the New York Stock Exchange, (ii) a banking
moratorium shall have been declared by either Federal or New York State
authorities or (iii) there shall have occurred any outbreak or escalation of
hostilities, declaration by the United States of a national emergency or war, or
other calamity or crisis the effect of which on financial markets is such as to
make it, in the sole 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).

                  11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors, employees, agents or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

                  12. Notices. All communications hereunder will be in writing
and effective only on receipt, and, if sent to the Representatives, will
be mailed, delivered or telefaxed to the

Insurance Holdings, Inc., 13403 Northwest Freeway, Houston, Texas 77040,

                  13. Successors. This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers, directors, employees, agents and controlling persons referred to in
Section 8 hereof, and no other person will have any right or obligation
hereunder.

                  14. Applicable Law. This Agreement will be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed within the State of New York.

                  15. Counterparts. This Agreement may be signed in one or more
counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement.

                  16. Headings. The section headings used herein are for
