Statement"; the Original Registration Statement and any Rule 462(b) Registration
Statement are hereinafter referred to collectively as the "Registration
Statement"; the U.S. prospectus and the international

         the circumstances under which they were made, not misleading, except
         that the representations and warranties set forth in this Section 1(b)
         do not apply to statements or omissions in the Registration Statement

         business or its ownership or leasing of property requires such
         qualification, except to the extent that the failure to be so qualified

         Company and its subsidiaries, taken as a whole.

                  (h) This Agreement and each of the Irrevocable Power of
         Attorney and Custody Agreements (collectively, the "Power of Attorney
         and Custody Agreements"), each dated the date hereof, by each Selling
         Shareholder and the Company as Custodian (the "Custodian"), appointing

                                        5


                  (k) There are no legal or governmental proceedings pending or
         threatened to which the Company or any of its subsidiaries is a party
         or to which any of the properties of the Company or any of its
         subsidiaries is subject that are required to be described in the
         Registration Statement or the Prospectus and are not so described or
         any statutes, regulations, contracts or other documents that are
         required to be described in the Registration Statement or the
         Prospectus or to be filed as exhibits to the Registration Statement
         that are not described or filed as required.

                  (l) Each of the Company and its subsidiaries has all necessary
         consents, authorizations, approvals, orders, certificates and permits
         of and from, and has made all declarations and filings with, all
         federal, state, local and other governmental authorities, all
         self-regulatory organizations and all courts and other tribunals, to
         own, lease, license and use its properties and assets and to conduct
         its business in the manner described in the Prospectus, except to the
         extent that the failure to obtain such consents, authorizations,
         approvals, orders, certificates and permits or make such declarations
         and filings would not have a material adverse effect on the Company and
         its subsidiaries, taken as a whole. Neither the Company nor any of its
         subsidiaries has received any notice of proceedings relating to the
         revocation or modification of any such consent, authorization,
         approval, order, certificate or permit which, singly or in the
         aggregate, if the subject of an unfavorable decision, ruling or
         finding, would result in a material adverse change in the condition,
         financial or otherwise, or in the earnings, business or operations of
         the Company and its subsidiaries, taken as a whole, except as described
         in or contemplated by the Prospectus.

                  (m) Each preliminary prospectus filed as part of the
         registration statement as originally filed or as part of any amendment
         thereto, or filed pursuant to Rule 424 under the Securities Act or
         incorporated by reference into or filed as part of the Rule 462(b)
         Registration Statement, complied when so filed in all material respects
         with the Securities Act and the rules and regulations of the Commission
         thereunder.

                  (n) The Company is not and, after giving effect to the
         offering and sale of the Shares and the application of the proceeds
         thereof as described in the Prospectus, will not be an "investment
         company" as such term is defined in the Investment Company Act of 1940,
         as amended.

                  (o) The Company and its subsidiaries are (i) in compliance
         with any and all applicable foreign, federal, state and local laws and
         regulations relating to the protection of human health and safety, the
         environment or hazardous or toxic substances or wastes, pollutants or
         contaminants ("Environmental Laws"), (ii) have received all permits,
         licenses or other approvals required of them under applicable
         Environmental Laws to conduct their respective businesses and (iii) are
         in compliance with all terms and conditions of any such permit, license
         or approval, except where such noncompliance with Environmental Laws,
         failure to receive required permits, licenses or other approvals or
         failure to comply with the terms and conditions of such


<PAGE>   7


                                        6


         permits, licenses or approvals would not, singly or in the aggregate,
         have a material adverse effect on the Company and its subsidiaries,
         taken as a whole.

                  (p) In the ordinary course of its business, the Company
         conducts a periodic review of the effect of Environmental Laws on the
         business, operations and properties of the Company and its
         subsidiaries, in the course of which it identifies and evaluates
         associated costs and liabilities (including, without limitation, any
         capital or operating expenditures required for clean-up, closure of
         properties or compliance with Environmental Laws or any permit, license
         or approval, any related constraints on operating activities and any
         potential liabilities to third parties). On the basis of such review,
         the Company has reasonably concluded that such associated costs and
         liabilities would not, singly or in the aggregate, have a material
         adverse effect on the Company and its subsidiaries, taken as a whole.

                  (q) Subsequent to the respective dates as of which information
         is given in the Registration Statement and the Prospectus, (1) the
         Company and its subsidiaries have not incurred any material liability
         or obligation, direct or contingent, nor entered into any material
         transaction not in the ordinary course of business; (2) the Company has
         not purchased any of its outstanding capital stock, nor declared, paid
         or otherwise made any dividend or distribution of any kind on its
         capital stock; and (3) there has not been any material change in the
         capital stock, short-term debt or long-term debt of the Company and its
         consolidated subsidiaries, except in each case as described in or
         contemplated by the Prospectus.

                  (r) The Company and its subsidiaries have good and marketable
         title in fee simple to all real property and good and marketable title
         to all personal property owned by them which is material to the
         business of the Company and its subsidiaries, in each case free and
         clear of all liens, encumbrances and defects except such as are
         described in the Prospectus or such as do not materially affect the
         value of such property and do not interfere with the use made and
         proposed to be made of such property by the Company and its
         subsidiaries; and any real property and buildings held under lease by
         the Company and its subsidiaries are held by them under valid,
         subsisting and enforceable leases with such exceptions as are not
         material and do not interfere with the use made and proposed to be made
         of such property and buildings by the Company and its subsidiaries, in
         each case except as described in or contemplated by the Prospectus.

                  (s) The Company and its subsidiaries own or possess, or can
         acquire on reasonable terms, all material patents, patent rights,
         licenses, inventions, copyrights, know-how (including trade secrets and
         other unpatented and/or unpatentable proprietary or confidential
         information, systems or procedures), trademarks, service marks and
         trade names currently employed by them in connection with the business
         now operated by them, and neither the Company nor any of its
         subsidiaries has received any notice of infringement of or conflict
         with asserted rights of others with


<PAGE>   8


                                        7


         respect to any of the foregoing which, singly or in the aggregate, if
         the subject of an unfavorable decision, ruling or finding, would result
         in any material adverse change in the condition, financial or
         otherwise, or in the earnings, business or operations of the Company
         and its subsidiaries, taken as a whole.

                  (t) No material labor dispute with the employees of the
         Company or any of its subsidiaries exists, except as described in or
         contemplated by the Prospectus, or, to the knowledge of the Company, is
         imminent; and the Company is not aware of any existing, threatened or
         imminent labor disturbance by the employees of any of its principal
         suppliers, manufacturers or contractors that could result in any
         material adverse change in the condition, financial or otherwise, or in
         the earnings, business or operations of the Company and its
         subsidiaries, taken as a whole.

                  (u) The Company and each of its subsidiaries are insured by
         insurers of recognized financial responsibility against such losses and
         risks and in such amounts as are prudent and customary in the
         businesses in which they are engaged; neither the Company nor any such
         subsidiary 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 materially and adversely affect the
         condition, financial or otherwise, or the earnings, business or
         operations of the Company and its subsidiaries, taken as a whole,
         except as described in or contemplated by the Prospectus.

                  (v) The Company and each of its subsidiaries maintain a system
         of internal accounting controls sufficient to provide reasonable
         assurance that (1) transactions are executed in accordance with
         management's general or specific authorizations; (2) transactions are
         recorded as necessary to permit preparation of financial statements in
         conformity with generally accepted accounting principles and to
         maintain asset accountability; (3) access to assets is permitted only
         in accordance with management's general or specific authorization; and
         (4) the recorded accountability for assets is compared with the
         existing assets at reasonable intervals and appropriate action is taken
         with respect to any differences.

                  (w) There are no holders of securities (debt or equity) of the
         Company or any of its subsidiaries, or holders of rights, options, or
         warrants to obtain securities of the Company or any of its
         subsidiaries, who have the right, during the 90 day period after the
         date of this Agreement to require the Company to register securities
         held by them under the Securities Act, other than holders who have
         waived such right for the 90 day period after the date of the public
         offering of the Shares and have waived their rights with respect to the
         inclusion of their securities in the Registration Statement.

         Selling Shareholder is a corporation), or the limited partnership
         agreement (if such Selling Shareholder is a limited partnership) or any
         agreement or other instrument binding upon such Selling Shareholder or
         any judgment, order or decree of any governmental body, agency or court
         having jurisdiction over such Selling Shareholder, and no consent,
         approval, authorization or order of, or qualification with, any
         governmental body or agency is required for the performance by such
         Selling Shareholder of its obligations under this Agreement or the

         notes thereto), in the Registration Statement and Prospectus is, and on
         the Closing Date (as defined below), in the case of a Firm Selling
         Shareholder, or the Option Closing Date (as defined below), in the case
         of an Option Selling Shareholder, will be, true, correct and complete,
         and does not, and on the Closing Date, in the case of a Firm Selling
         Shareholder, or the Option Closing Date, in the case of an Option
         Selling Shareholder, will not, contain any untrue statement of material
         fact or omit to state any material fact necessary to make such
         information not misleading.

                  3. Agreements to Sell and Purchase. Each Firm Seller,
severally and not jointly, hereby agrees to sell to the several Underwriters,
and each Underwriter, upon the basis of the representations and warranties
herein contained, but subject to the conditions hereinafter stated, agrees,
severally and not jointly, to purchase from such Firm Seller at U.S.$[_______] a
share (the "Purchase Price") the number of Firm Shares (subject to such
adjustments to eliminate fractional shares as you may determine) that bears the
same proportion to the number of Firm Shares to be sold by such Firm Seller as
the number of Firm Shares set forth in Schedules I and II hereto opposite the
name of such Underwriter bears to the total number of Firm Shares.

                  On the basis of the representations and warranties contained
in this Agreement, and subject to its terms and conditions, the Company and the
Option Selling Shareholders severally agree to sell to the U.S. Underwriters the
Additional Shares, and the U.S. Underwriters shall have a one-time right to
purchase, severally and not jointly, up to 1,260,000 Additional Shares at the
Purchase Price. If you, on behalf of the U.S. Underwriters, elect to exercise
such option, you shall so notify the Company and the Option Selling Shareholders
in writing not later than 30 days after the date of this Agreement, which notice
shall specify the number of Additional Shares to be purchased by the U.S.
Underwriters and the date on which such shares are to be purchased. Such date
may be the same as the Closing Date (as defined below) but not earlier than the
Closing Date nor later than ten business days after the date of such notice.
Additional Shares may be purchased as provided in Section 5 hereof solely for
the purpose of covering over-allotments made in connection with the offering of
the Firm Shares. If any Additional Shares are to be purchased, each U.S.
Underwriter agrees, severally and not jointly, to purchase the number of
Additional Shares (subject to such adjustments to eliminate fractional shares as
the U.S. Representatives may determine) that bears the same proportion to the
total number of Additional Shares to be purchased as the number of U.S. Firm
Shares set forth in Schedule I hereto opposite the name of such U.S. Underwriter
bears to the total number of U.S. Firm Shares.

                  Each Seller hereby agrees that, without the prior written
consent of Morgan Stanley & Co. Incorporated ("Morgan Stanley"), it will not,
for a period of 90 days after the date of the Prospectus, (i) offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase,
lend, or otherwise transfer or dispose of, directly or indirectly, any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for Common

another, in whole or in part, any of the economic consequences of ownership of
such shares of Common Stock, whether any such transaction described in clause
(i) or (ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise, other than (a) the sale of the Shares to the
Underwriters pursuant to this Agreement, (b) transactions relating to shares of
Common Stock or other securities acquired in open market transactions after the
completion of the public offering of the Common Stock hereunder or (c) the
issuance by the Company of shares of Common Stock upon the exercise of an option
or warrant or the conversion of a security outstanding on the date hereof of
which the Underwriters have been advised in writing.

                  In addition, each Selling Shareholder agrees that, without the
prior written consent of Morgan Stanley on behalf of the Underwriters, it will
not, for a period of 90 days after the date of the Prospectus, make any demand
for or exercise any right with respect to, the registration of any shares of
Common Stock or any security convertible into or exercisable or exchangeable for
Common Stock.

                  4. Terms of Public Offering. The Sellers are advised by you
that the Underwriters propose to make a public offering of their respective
portions of the Shares as soon after the Original Registration Statement and
this Agreement have become effective as in your judgment is advisable. The
Sellers are further advised by you that the Shares are to be offered to the
public initially at U.S.$[____] a share (the "Public Offering Price") and to
certain dealers selected by you at a price that represents a concession not in
excess of U.S.$[__] a share under the Public Offering Price, and that any
Underwriter may allow, and such dealers may reallow, a concession, not in excess
of U.S.$[__] a share, to any Underwriter or to certain other dealers.

                  Each U.S. Underwriter hereby makes to and with the Company and
each Selling Shareholder the representations and agreements of such U.S.
Underwriter contained in the fifth and sixth paragraphs of Article III of the
Agreement Between U.S. and International Underwriters of even date herewith.
Each International Underwriter hereby makes to and with the Company and each
Selling Shareholder the representations and agreements of such International
Underwriter contained in the seventh, eighth, ninth and tenth paragraphs of
Article III of such Agreement.

                  5. Payment and Delivery. Payment for the Firm Shares to be
sold by each Firm Seller shall be made by wire transfers to the Company's
account and the Custodian's account (for the benefit of the Firm Selling
Shareholders) in federal funds or other funds immediately available in New York

                  (a) Whether or not the transactions contemplated hereby are
         consummated or this Agreement is terminated, to pay or cause to be paid
         (i) all taxes, if any, on the transfer and sale of the Shares being
         sold by such Selling Shareholder and (ii) all expenses incident to the
         delivery of the Shares and the fees and expenses of counsel and
         accountants for such Selling Shareholder; provided that the provisions
         of this Section 8(a) and Section 7(h) shall not in any way affect any
         agreement between the Company and the Selling Shareholders with respect
         to the payment of expenses.

                  (b) Such Selling Shareholder has carefully reviewed the
         Registration Statement and will carefully review, promptly upon
         receipt, each amendment thereto provided to such Selling Shareholder.
         At any time during the period from the date hereof through the Closing
         Date or the Option Closing Date, in the case of an Option Selling
         Shareholder, if there is any change in the information in the
         Registration Statement as set forth under the caption "Principal and
         Selling Shareholders" (including the notes thereto) that specifically
         relate to such Selling Shareholder, such Selling Shareholder will
         immediately notify the Company of such change.

                  (c) Such Selling Shareholder shall cooperate fully with the
         Company in supplying such information relating to such Selling
         Shareholder and the Shares as the Company may reasonably request for
         use in preparation of the Registration Statement and all other
         documents reasonably necessary or desirable in connection with the
         offering of Shares. In addition, such Selling Shareholder shall furnish
         to the Company (or, at the Company's request, to the Underwriters or
         other parties) such further certificates and documents confirming the
         representations and warranties contained herein, or with respect to
         related matters, as the Company may reasonably request.

                  9.  Indemnity and Contribution. (a) The Company agrees to
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of either Section 15 of the
Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), from and against any and all losses, claims, damages and
liabilities (including, without limitation, any legal or other expenses
reasonably incurred by any Underwriter or any such controlling person in


<PAGE>   18


                                       17


connection with defending or investigating any such action or claim) caused by
any untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement or any amendment thereof, any preliminary prospectus
or the Prospectus (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto), or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information relating to any Underwriter furnished to the Company in writing by
such Underwriter through you expressly for use therein; provided, however, that
the foregoing indemnity agreement with respect to any preliminary prospectus
shall not inure to the benefit of any Underwriter from whom the person asserting
such losses, claims, damages or liabilities purchased Shares, or any person
controlling such Underwriter, if a copy of the Prospectus (as then amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) was not sent or given by or on behalf of such Underwriter to such
person, if required by law so to have been delivered, at or prior to the written
confirmation of the sale of the Shares to such person, and if the Prospectus (as
so amended or supplemented) would have cured the defect giving rise to such
losses, claims, damages or liabilities.

                  (b) Each Selling Shareholder agrees, severally and not
jointly, to indemnify and hold harmless the Company, its directors, its officers
who sign the Registration Statement, each Underwriter and each person, if any,
who controls the Company or any Underwriter within the meaning of either Section
15 of the Securities Act or Section 20 of the Exchange Act from and against any
and all losses, claims, damages and liabilities (including, without limitation,
any legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or any amendment thereof, any preliminary prospectus or the Prospectus
(as amended or supplemented if the Company shall have furnished any amendments
or supplements thereto), or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, but only with reference to information
relating to such Selling Shareholder, as set forth under the caption "Principal
and Selling Stockholders" (including the notes thereto) in the Prospectus and
Registration Statement or any amendment or supplement thereto; provided,
however, that the foregoing indemnity agreement with respect to any preliminary
prospectus shall not inure to the benefit of any Underwriter from whom the
person asserting such losses, claims, damages or liabilities purchased Shares,
or any person controlling such Underwriter, if a copy of the Prospectus (as then
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Underwriter
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the Shares to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such losses, claims, damages or liabilities; provided, further, that
with respect to any amount due an indemnified


<PAGE>   19


                                       18


person under this paragraph (b), each Selling Shareholder shall be liable only
to the extent of the net proceeds received by such Selling Shareholder from the
sale of such Selling Shareholder's Shares.

                  (c) Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, its directors, its officers who sign
the Registration Statement, the Selling Shareholders and each person, if any,
who controls the Company or any Selling Shareholder within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with
defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or any amendment thereof, any preliminary prospectus or
the Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only with reference
to information relating to such Underwriter furnished to the Company in writing
by such Underwriter through you expressly for use in the Registration Statement,
any preliminary prospectus, the Prospectus or any amendments or supplements
thereto.

                  (d) The Company also agrees to indemnify and hold harmless
Morgan Stanley and each person, if any, who controls Morgan Stanley within the
meaning of either Section 15 of the Securities Act, or Section 20 of the
Exchange Act, from and against any and all losses, claims, damages, liabilities
and judgments incurred as a result of Morgan Stanley's participation as a QIU in
connection with the offering of the Common Stock, except for any losses, claims,
damages, liabilities, and judgments resulting from Morgan Stanley's, or such
controlling person's, willful misconduct.

                   (e) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to subsection (a), (b), (c) or (d) of this
Section 9, such person (the "indemnified party") shall promptly notify the
person against whom such indemnity may be sought (the "indemnifying party") in
writing and the indemnifying party, upon request of the indemnified party, shall
retain counsel reasonably satisfactory to the indemnified party to represent the
indemnified party and any others the indemnifying party may designate in such
proceeding and shall pay the fees and disbursements of such counsel related to
such proceeding. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the indemnifying party
and the indemnified party shall have mutually agreed to the retention of such
counsel or (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified party
and representation of both parties by the same counsel would be inappropriate
due to actual or potential differing interests between them. It is understood
that the indemnifying party shall not, in respect of the legal expenses of any
indemnified party in connection with any proceeding or related


<PAGE>   20


                                       19


proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for (i) all
Underwriters and all persons, if any, who control any Underwriter within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act, (ii) the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning
of either such Section and (iii) all Selling Shareholders and all persons, if
any, who control any Selling Shareholder within the meaning of either such
Section, and that all such fees and expenses shall be reimbursed as they are
incurred. In the case of any such separate firm for the Underwriters and such
control persons of Underwriters, such firm shall be designated in writing by
Morgan Stanley. In the case of any such separate firm for the Company, and such
directors, officers and control persons of the Company, such firm shall be
designated in writing by the Company. In the case of any such separate firm for
the Selling Shareholders and such controlling persons of Selling Shareholders,
such firm shall be designated in writing by the Selling Shareholders selling a
majority of the Selling Shareholders' Shares hereunder. Notwithstanding anything
contained herein to the contrary, if indemnity may be sought pursuant to
subsection (d) of this Section 9 in respect of such action or proceeding, then
in addition to such separate firm for the indemnified parties, the indemnifying
party shall be liable for the reasonable fees and expenses of not more than one
separate firm (in addition to any local counsel) for Morgan Stanley in its
capacity as a QIU and all persons, if any, who control Morgan Stanley within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act. The indemnifying party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as contemplated by the second and third sentences of this subsection,
the indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid, request and (ii) such indemnifying party shall not have reimbursed
the indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party,
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

                  (f) To the extent the indemnification provided for in
subsection (a), (b), (c) or (d) of this Section 9 is unavailable to an
indemnified party or insufficient in respect of any losses, claims, damages or
liabilities referred to therein, then each indemnifying party under such
subsection, in lieu of indemnifying such indemnified party thereunder, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits


<PAGE>   21


                                       20


received by the indemnifying party or parties on the one hand and the
indemnified party or parties on the other hand from the offering of the Shares
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the indemnifying party or parties on the one hand and of the indemnified party
or parties on the other hand in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the Sellers
on the one hand and the Underwriters on the other hand in connection with the
offering of the Shares shall be deemed to be in the same respective proportions
as the net proceeds from the offering of the Shares (before deducting expenses)
received by each Seller and the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover of the Prospectus, bear to the aggregate Public Offering Price of the
Shares. The relative fault of a Seller and of the Underwriters shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by such Seller or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The
Underwriters' respective obligations to contribute pursuant to this Section 9
are several in proportion to the respective number of Shares they have purchased
hereunder, and not joint. In no event shall the liability of a Selling
Shareholder under this Section 9(f) exceed the amount that such Selling
Shareholder would have been required to pay under Section 9(b) had such
indemnification been held to be available thereunder.

                  (g) The Sellers and the Underwriters agree that it would not
be just or equitable if contribution pursuant to this Section 9 were determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to in subsection (f) of this Section 9.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in subsection (f) of this Section 9
shall be deemed to include, subject to the limitations set forth above, any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 9, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages that such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The remedies provided for in this Section 9 are
not exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

                                       21


                  (h) The indemnity and contribution provisions contained in
this Section 9 and the representations and warranties and other statements of
the Company and the Selling Shareholders contained in this Agreement shall
remain operative and in full force and effect regardless of (i) any termination
of this Agreement, (ii) any investigation made by or on behalf of any
Underwriter or any person controlling any Underwriter, any Selling Shareholder
or any person controlling any Selling Shareholder, or the Company, its officers
or directors or any person controlling the Company and (iii) acceptance of and
payment for any of the Shares.

                  10. Termination. This Agreement shall be subject to
termination by notice given by you to the Company, if (a) after the execution
and delivery of this Agreement and prior to the Closing Date (i) trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange, the American Stock Exchange, the
NASD, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or
the Chicago Board of Trade, (ii) trading of any securities of the Company shall
have been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have been
declared by either federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in your judgment, is material
and adverse and (b) in the case of any of the events specified in clauses (a)(i)
through (iv), such event singly or together with any other such event makes it,
in your judgment, impracticable to market the Shares on the terms and in the
manner contemplated in the Prospectus.

                  11. Effectiveness; Defaulting Underwriters. This Agreement
shall become effective upon the later of (x) execution and delivery hereof by
the parties hereto and (y) release of notification of the effectiveness of the
Original Registration Statement by the Commission.

                  If, on the Closing Date or the Option Closing Date, as the
case may be, any one or more of the Underwriters shall fail or refuse to
purchase Shares that it or they have agreed to purchase hereunder on such date,
and the aggregate number of Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase is not more than one-tenth
of the aggregate number of the Shares to be purchased on such date, the other
Underwriters shall be obligated severally in the proportions that the number of
Firm Shares set forth opposite their respective names in Schedule I or Schedule
II bears to the aggregate number of Firm Shares set forth opposite the names of
all such nondefaulting Underwriters, or in such other proportions as you may
specify, to purchase the Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date; provided
that in no event shall the number of Shares that any Underwriter has agreed to
purchase pursuant to this Agreement be increased pursuant to this Section 11 by
an amount in excess of one-ninth of such number of Shares without the written
consent of such Underwriter. If, on the Closing Date or the Option Closing Date,
as the case may be, any Underwriter or Underwriters shall fail or refuse to
purchase Shares and the aggregate number


<PAGE>   23


                                       22


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

                  If this Agreement shall be terminated by the Underwriters, or
any of them, because of any failure or refusal on the part of any Seller to
comply with the terms or to fulfill any of the conditions of this Agreement, or
if for any reason any Seller shall be unable to perform its obligations under
this Agreement, the Company will reimburse the Underwriters or such Underwriters
as have so terminated this Agreement with respect to themselves, severally, for
all out-of-pocket expenses (including the fees and disbursements of their
counsel) reasonably incurred by such Underwriters in connection with this
Agreement or the offering contemplated hereunder.

                  12. Counterparts. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

                  13. Applicable Law. This Agreement shall be governed by the
laws of the State of New York.

         or otherwise, or in the earnings, business or operations of the Company
