     reference in the prospectus contained in the Initial Registration Statement
     at the time such part of the Initial Registration Statement became
     effective, each such incorporated document as amended at the time such part

     collectively called the "Registration Statement"; and such final
     prospectus, in the form first filed pursuant to Rule 424(b) under the Act,
     is hereinafter called the "Prospectus"; and any reference herein to any
     Preliminary Prospectus or the Prospectus shall be deemed to refer to and

     Prospectus, at the time of filing thereof, conformed in all material
     respects to the requirements of the Act and the rules and regulations of
     the Commission thereunder, and did not include an untrue statement of a
     material fact or omit to state a material fact required to be set forth
     therein or necessary in order to make the statements therein, in the light
     of the circumstances under which they were made, not misleading; provided,
     however, that this representation and warranty shall not apply to any
     statements or omissions made in reliance upon and in conformity with
     information furnished in writing to the Company by an Underwriter through
     Goldman, Sachs & Co. expressly for use therein or by a Selling Stockholder
     expressly for use in the preparation of the answers therein to Item 7 of
     Form S-3;

       (iii)  The documents incorporated by reference in the Prospectus, when
     they became effective or were filed with the Commission, as the case may

     fact required to be stated therein necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company
     by an Underwriter through Goldman, Sachs & Co. expressly for use therein;

       (iv) The Registration Statement conforms, and the Prospectus and any
     further amendments or supplements to the Registration Statement or the
     Prospectus will conform, in all material respects to the requirements of
     the Act and the rules and regulations of the Commission thereunder and do
     not and will not, as of the applicable effective date as to the
     Registration Statement and any amendment thereto and as of the applicable
     filing date as to the Prospectus and any amendment or supplement thereto,
     contain an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company
     by an Underwriter through Goldman, Sachs & Co. expressly for use therein or
     by a Selling Stockholder expressly for use in the preparation of the
     answers therein to Item 7 of Form S-3;

     with its business from fire, explosion, flood or other calamity, whether or
     not covered by insurance, or from any labor dispute or court or
     governmental action, order or decree, in each case which is reasonably
     likely, currently or prospectively, to have a material adverse effect on
     the financial position, stockholders' equity or results of operations of
     the Company and its consolidated Subsidiaries taken as a whole (such
     effect, a "Material Adverse Effect"); and, since the respective dates as of
     which information is given in the Registration Statement and the
     Prospectus, there has not been any change in the capital stock of the
     Company (other than issuances of capital stock upon exercise of options and
     stock appreciation rights, upon earn-outs of performance shares and upon
     conversions of convertible securities, in each case which were outstanding
     on the date of the latest balance sheet included or incorporated by
     reference in the Prospectus) or increase in long-term debt of the Company
     and its consolidated Subsidiaries taken as a whole (other than (i)
     increases after such dates in such long-term debt resulting solely from the
     translation to United States dollars of long-term debt denominated in a
     currency other than the United States dollar (which increases do not have a
     Material Adverse Effect), (ii) increases of up to $25 million after such
     dates in such long-term debt resulting solely from the reclassification of
     debt of the Company and its consolidated Subsidiaries that is classified as
     current debt as of such dates to long-term debt and (iii) other increases
     in such long-term debt of up to $5 million) or any development that is
     reasonably likely, currently or prospectively, to have a Material Adverse
     Effect;

       (vi) The Company or one of its Subsidiaries has good and marketable title
     in fee simple to all real property and good and marketable title to all
     personal property owned by them, in each case free and clear of all liens,

                                       3

  
     Prospectus or such as do not materially and adversely affect the financial
     condition of the Company and its consolidated Subsidiaries taken as a
     whole; and any real property and buildings held under lease by the Company
     or one of its Subsidiaries are held by them under valid, subsisting and
     enforceable leases with such exceptions as are not reasonably likely,
     currently or prospectively, to have a Material Adverse Effect;

       (vii) The Company has been duly incorporated and is validly existing as a
     corporation in good standing under the laws of the State of Delaware, with
     power and authority (corporate and other) to own its properties and conduct
     its business as described in the Prospectus, and has been duly qualified as
     a foreign corporation for the transaction of business and is in good
     standing under the laws of each other jurisdiction in which it owns or
     leases properties or conducts any business so as to require such
     qualification, or is subject to no liability or disability by reason of the
     failure to be so qualified in any such jurisdiction which is reasonably
     likely, currently or prospectively, to have a Material Adverse Effect; and
     each Subsidiary of the Company has been duly incorporated and is validly
     existing as a corporation in good standing under the laws of its
     jurisdiction of incorporation;

       (viii) The Company has an authorized capitalization as set forth in the
     Prospectus, and all of the issued shares of capital stock of the Company
     have been duly and validly authorized and issued, are fully paid and non-
     assessable (except to the extent that such shares are assessable as
     provided in Section 180.0622 of the Wisconsin Business Corporation Law as
     interpreted by the courts of the State of Wisconsin) and conform to the
     description of the Stock contained in the Prospectus under the caption
     "Description of Capital Stock"; and all of the issued shares of capital
     stock of each Subsidiary of the Company have been duly and validly
     authorized and issued, are fully paid and non-assessable and (except for
     directors' qualifying shares) are owned directly or indirectly by the
     Company, free and clear of all liens, encumbrances, equities or claims;

       (ix) The unissued Shares to be issued and sold by the Company to the
     Underwriters hereunder have been duly and validly authorized and, when
     issued and delivered against payment therefor as provided herein, will be
     duly and validly issued and fully paid and non-assessable (except to the
     extent that such shares are assessable as provided in Section 180.0622 of
     the Wisconsin Business Corporation Law as interpreted by the courts of the
     State of Wisconsin) and will conform to the description of the Stock
     contained in the Prospectus under the caption "Description of Capital

       (x)  The issue and sale of the Shares to be sold by the Company and the

     of its Subsidiaries is a party or by which the Company or any of its
     Subsidiaries is bound or to which any of the property or assets of the
     Company or any of its Subsidiaries is subject, nor will such action result
     in any violation of the provisions of the Amended and Restated Certificate
     of Incorporation or By-laws of the Company or any statute or any order,
     rule or regulation of any court or governmental agency or body having
     jurisdiction over the Company or any of its Subsidiaries or any of their
     properties; and no consent, approval, authorization, order, registration or
     qualification of or with any such court or

                                       4

  
     governmental agency or body is required for the issue and sale of the
     Shares or the consummation by the Company of the transactions contemplated
     by this Agreement, except the registration under the Act of the Shares and
     such consents, approvals, authorizations, registrations or qualifications
     as may be required by the New York Stock Exchange (the "Exchange"), the

     indenture, mortgage, deed of trust, loan agreement, lease or other
     agreement or instrument to which it is a party or by which it or any of its
     properties may be bound, which violation or default is reasonably likely,
     currently or prospectively, to have a Material Adverse Effect;

       (xii) The statements set forth in the Prospectus under the caption
     "Description of Capital Stock", constitute an accurate summary of the terms
     of the Stock;

       (xiii) Other than as set forth in the Prospectus, there are no legal or
     governmental proceedings pending to which the Company or any of its
     Subsidiaries is a party or of which any property of the Company or any of
     its Subsidiaries is the subject which is reasonably likely, currently or
     prospectively, individually or in the aggregate, to have a Material Adverse
     Effect; and, to the best of the Company's knowledge, no such proceedings
     are threatened by governmental authorities or others;

       (xiv)  The Company is not and, after giving effect to the offering and
     sale of the Shares, will not be an "investment company" or an entity
     "controlled" by an "investment company", as such terms are defined in the

     other agreement or instrument to which such Selling Stockholder is a party
     or by which such Selling Stockholder is bound or to which any of the

     security of the Company to facilitate the sale or resale of the Shares;

          (vi)   To the extent that any statements or omissions made in the
     Registration Statement, any Preliminary Prospectus, the Prospectus or any

     delivered by or on behalf of the Selling Stockholders in accordance with
     the terms and conditions of this Agreement and each Selling Stockholder's
     respective Custody Agreement and Power of Attorney; and actions taken by
     the Attorneys-in-Fact pursuant to any Custody Agreement and Power of

          (x)    Except as otherwise disclosed to the Underwriters in writing,

purchase from the Company and each of the Selling Stockholders, at a purchase
price per share of $_____, the number of Firm Shares (to be adjusted by you so
as to eliminate fractional shares) determined by multiplying the aggregate
number of Firm Shares to be sold by each of the Selling Stockholders as set

                                       8

 
Shares which such Underwriter is entitled to purchase as set forth opposite the

     The Company hereby grants to the Underwriters the right to purchase at

     fact or omit to state any material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made when such Prospectus is delivered, not misleading, or, if for any

          in the Registration Statement or the Prospectus, except for those
          referred to in the opinion in subsection (viii) of this Section 7(c),
          and relying as to certain facts relevant to determining materiality
          upon the statements and representations of officers and
          representatives of the Company, nothing has come to their attention
          which causes them to believe that, as of its effective date, the
          Registration Statement or any further amendment thereto made by the
          Company prior to such Time of Delivery (other than the financial
          statements, financial data and schedules included therein, as to which

          schedules included therein, as to which such counsel need express no
          belief) included an untrue statement of a material fact or omitted to
          state a material fact necessary to make the statements therein, in the
          light of the circumstances under which they were made, not misleading
          or that, as of such Time of Delivery, either the Registration
          Statement or the Prospectus or any further amendment or supplement
          thereto made by the Company prior to such Time of Delivery (other than
          the financial statements, financial data and schedules included
          therein, as to which such counsel need express no belief) includes an
          untrue statement of a material fact or omits to state a material fact
          necessary to make the statements therein, in the light of the
          circumstances under which they were made, not misleading; and they do
          not know of any amendment to the Registration Statement required to be
          filed or of any contracts or other documents of a character required
          to be filed as an exhibit to the Registration Statement or required to
          be incorporated by reference into the Prospectus or required to be
          described in the Registration Statement or the Prospectus which are
          not filed or incorporated by reference or described as required;

                                       15

 
          (d)  The respective counsel for each of the Selling Stockholders, as
     indicated in Schedule II hereto, each shall have furnished to you their
     written opinion with respect to each of the Selling Stockholders for whom
     they are acting as counsel, dated the First Time of Delivery, in form and
     substance satisfactory to you, to the effect that:

               (i)    A Custody Agreement and Power of Attorney has been duly
          executed and delivered by such Selling Stockholder and constitutes a
          valid and binding agreement of such Selling Stockholder enforceable in
          accordance with its terms except to the extent enforceability may be
          limited by applicable bankruptcy, insolvency, reorganization,
          moratorium, fraudulent transfer or other similar laws affecting the
          enforcement of creditors' rights generally and by the effect of
          general principles of equity, regardless of whether enforceability is
          considered in a proceeding in equity or at law;

               (ii)   This Agreement has been duly executed and delivered by or
          on behalf of such Selling Stockholder; and the sale of the Shares to
          be sold by such Selling Stockholder hereunder and the compliance by
          such Selling Stockholder with all of the provisions of this Agreement,
          such Selling Stockholder's Custody Agreement and Power of Attorney and
          the consummation of the transactions herein and therein contemplated
          will not conflict with or result in a breach or violation of any terms
          or provisions of, or constitute a default under, any statute,
          indenture, mortgage, deed of trust, loan agreement or other agreement
          or instrument known to such counsel to which such Selling Stockholder
          is a party or by which such Selling Stockholder is bound or to which
          any of the property or assets of such Selling Stockholder is subject,
          nor will such action result in any violation of the provisions of the
          trust agreement of such Selling Stockholder if such Selling
          Stockholder is a trust, the charter or by-laws (or other governing
          document) of such Selling Stockholder if such Selling Stockholder is a
          corporation or any order, rule or regulation known to such counsel of
          any court or governmental agency or body having jurisdiction over such
          Selling Stockholder or the property of such Selling Stockholder;

               (iii)  No consent, approval, authorization or order of any court
          or governmental agency or body is required for the consummation of the
          transactions contemplated by this Agreement in connection with the
          Shares to be sold by such Selling Stockholder hereunder, except such
          as have been obtained under the Act and such as may be required under
          state securities or Blue Sky laws in connection with the purchase and
          distribution of such Shares by the Underwriters and the clearance of
          such distribution with the NASD;

               (iv)   Immediately prior to the First Time of Delivery, such
          Selling Stockholder had full right, power and authority to sell,
          assign, transfer and deliver the Shares to be sold by such Selling
          Stockholder hereunder; and

               (v)    Good and valid title to such Shares, free and clear of all
          liens, encumbrances, equities or claims, has been transferred to each
          of the several Underwriters who have purchased such Shares in good
          faith and without notice of any such lien, encumbrance, equity or
          claim or any other adverse claim within the meaning of the Uniform
          Commercial Code.

                                       16

 
          (e)    On the date of the Prospectus simultaneous with the execution
     of this Agreement, on the effective date of any post-effective amendment to
     the Registration Statement filed subsequent to the date of this Agreement
     and also at each Time of Delivery, Price Waterhouse L.L.P. shall have
     furnished to you a letter or letters, dated the respective dates of
     delivery thereof, in form and substance satisfactory to you, to the effect
     set forth in Annex I hereto;

          (f)(i) Neither the Company nor any of its Subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included in the Prospectus any loss or interference with its business from
     fire, explosion, flood or other calamity, whether or not covered by
     insurance, or from any labor dispute or court or governmental action, order
     or decree, and (ii) since the respective dates as of which information is
     given in the Prospectus there shall not have been any change in the capital
     stock of the Company (other than issuances of capital stock upon exercise
     of options and stock appreciation rights, upon earn-outs of performance
     shares and upon conversions of convertible securities, in each case which
     were outstanding on the date of the latest balance sheet included or
     incorporated by reference in the Prospectus) or increase in long-term debt
     of the Company and its consolidated Subsidiaries taken as a whole (other
     than (i) increases after such dates in such long-term debt resulting solely
     from the translation to United States dollars of long-term debt denominated
     in a currency other than the United States dollar (which increases do not
     have a Material Adverse Effect), (ii) increases of up to $25 million after
     such dates in such long-term debt resulting solely from the
     reclassification of debt of the Company and its consolidated Subsidiaries
     that is classified as current debt as of such dates to long-term debt and
     (iii) other increases in such long-term debt of up to $5 million) or any
     change, or any development that is reasonably likely, currently or
     prospectively, have a Material Adverse Effect, which is not set forth or
     contemplated in the Prospectus and the effect of which, in any such case
     described in Clause (i) or (ii), is in the judgment of the Representatives
     so material and adverse as to make it impracticable or inadvisable to
     proceed with the public offering or the delivery of the Shares being
     delivered at such Time of Delivery on the terms and in the manner
     contemplated in the Prospectus;

          (g)    On or after the date hereof there shall not have occurred any
     of the following: (i) a suspension or material limitation in trading in
     securities generally on the Exchange; (ii) a suspension or material
     limitation in trading in the Company's securities on the Exchange; (iii) a
     general moratorium on commercial banking activities declared by either
     Federal or New York or Illinois State authorities; or (iv) the outbreak or
     escalation of hostilities involving the United States or the declaration by
     the United States of a national emergency or war, if the effect of any such
     event specified in this Clause (iv) in the judgment of the Representatives
     makes it impracticable or inadvisable to proceed with the public offering
     or the delivery of the Shares being delivered at such Time of Delivery on
     the terms and in the manner contemplated in the Prospectus;

          (h)    The Shares at such Time of Delivery shall have been duly
     listed, subject to notice of issuance, on the Exchange;

          (i)    The Company has obtained and delivered to the Underwriters
     executed copies of an agreement from members of the Current Harris Group
     (as defined in the Prospectus) (other than Selling Stockholders) owning
     (together with those members of the Current Harris Group that are Selling
     Stockholders) no less than 98% of the shares of Stock owned by the Current
     Harris Group in the aggregate, substantially to the effect set forth in
     Subsection 1(b)(iv) hereof (provided that the

                                       17

 
     time period covered by such agreement shall be from the date hereof to and
     including the date 120 days after the date of the First Time of Delivery)
     in form and substance satisfactory to you; and

           (j)   The Company and the Selling Stockholders shall have furnished
     or caused to be furnished to you at such Time of Delivery certificates of
     an officer of the Company and of the Selling Stockholders, respectively,
     satisfactory to you as to the accuracy of the representations and
     warranties of the Company and the Selling Stockholders, respectively,
     herein at and as of such Time of Delivery, as to the performance by the
     Company and the Selling Stockholders of all of their respective obligations
     hereunder to be performed at or prior to such Time of Delivery, and as to
     such other matters as you may reasonably request, and the Company shall
     have furnished or caused to be furnished certificates as to the matters set
     forth in subsections (a) and (f) of this Section.

     8.   (a)    The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment 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 will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall 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 an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein.

     (b)  Each Selling Stockholder will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities to which such
Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in any Preliminary Prospectus, the Registration Statement or
the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such Selling
Stockholder expressly for use therein; and will reimburse each Underwriter for
any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that the liability of any Selling
Stockholder pursuant to this subsection (b) shall not exceed the product of the
number of Shares sold by such Selling Stockholder and the initial public
offering price of the Shares as set forth in the Prospectus.

     (c)  Each Underwriter will indemnify and hold harmless the Company and each
Selling Stockholder against any losses, claims, damages or liabilities to which
the Company or such Selling

                                       18

 
Stockholder may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in any Preliminary Prospectus, the Registration Statement or
the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through Goldman, Sachs & Co. expressly for use therein; and will reimburse the
Company and each Selling Stockholder for any legal or other expenses reasonably
incurred by the Company or such Selling Stockholder in connection with
investigating or defending any such action or claim as such expenses are
incurred.

     (d)  Promptly after receipt by an indemnified party under subsection (a),
(b) or (c) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any indemnified party. No indemnified party shall, without the
written consent of the indemnifying party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnifying party is an actual or
potential party to such action or claim).

     (e)  If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under subsection (a),
(b) or (c) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
under subsection (a), (b) or (c) above, as the case may be, shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to in
subsection (a), (b) or (c) above, as the case may be, in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Selling Stockholders in question on the one

                                       19

 
hand and the Underwriters on the other from the offering of the Shares. If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (d) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company and the Selling Stockholders in question on
the one hand and the Underwriters on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Selling
Stockholders in question on the one hand and the Underwriters on the other shall
be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company and the Selling
Stockholders in question bear to the total underwriting discounts and
commissions received by the Underwriters, in each case as set forth in the table
on the cover page of the Prospectus. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Selling Stockholders in
question on the one hand or the Underwriters on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company, each of the Selling
Stockholders and the Underwriters agree that it would not be just and equitable
if contributions pursuant to this subsection (e) were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this subsection (e). The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to above in this
subsection (e) shall be deemed to include 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 subsection (e),
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 which 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 Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations in
this subsection (e) to contribute are several in proportion to their respective
underwriting obligations and not joint.

     (f)  The respective obligations of the Company and the Selling Stockholders
under this Section 8 shall be in addition to any liability which the Company or
such Selling Stockholder may otherwise have and shall extend, upon the same
terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 8 shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company and to each person, if
any, who controls the Company or any Selling Stockholder within the meaning of
the Act.

     9.   (a)  If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company and the Selling Stockholders shall be entitled to
a further period of thirty-six hours within which to procure

                                       20

 
another party or other parties satisfactory to you to purchase such Shares on
such terms. In the event that, within the respective prescribed periods, you
notify the Company and the Selling Stockholders that you have so arranged for
the purchase of such Shares, or the Company and the Selling Stockholders notify
you that they have so arranged for the purchase of such Shares, you or the
Company and the Selling Stockholders shall have the right to postpone such Time
of Delivery for a period of not more than seven days, in order to effect
whatever changes may thereby be made necessary in the Registration Statement or
the Prospectus, or in any other documents or arrangements, and the Company
agrees to file promptly any amendments to the Registration Statement or the
Prospectus which in your opinion may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to this Agreement with respect to such Shares.

     (b)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of Delivery,
then the Company and the Selling Stockholders shall have the right to require
each non-defaulting Underwriter to purchase the number of Shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     (c)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Company and the Selling Stockholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Company to sell the Optional Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company or the Selling Stockholders, except for the expenses
to be borne by the Company and the Selling Stockholders and the Underwriters as
provided in Section 6 hereof and the indemnity and contribution agreements in
Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

     10.  (a)  The respective indemnities, agreements, representations,
warranties and other statements of the Company, the Selling Stockholders and the
several Underwriters, as set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement, shall remain in full force and
effect, regardless of any investigation (or any statement as to the results
thereof) made by or on behalf of any Underwriter or any controlling person of
any Underwriter, or the Company, or any of the Selling Stockholders, or any
officer or director or controlling person of the Company, or any controlling
person of any Selling Stockholder, and shall survive delivery of and payment for
the Shares.

     (b)  The Company, the Underwriters and the Selling Stockholders hereby
agree that, for any purpose whatsoever, including without limitation Sections
1(b)(vi) and 8(b) of this Agreement, the only

                                       21

 
written information furnished to the Company by any Selling Stockholder
expressly for use in the Registration Statement, any Preliminary Prospectus or
the Prospectus or any amendment or supplement thereto is the information
relating to such Selling Stockholder under the heading "Principal and Selling
Stockholders" in the Prospectus.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Company (with respect to the Optional Shares only) and the Selling Stockholders
(with respect to the Firm Shares only) as provided herein, the Company and each
of the Selling Stockholders pro rata (based on the number of Shares to be sold
by the Company and such Selling Stockholder hereunder) will reimburse the
Underwriters through you for all out-of-pocket expenses approved in writing by
you, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Shares not so delivered, but the Company and the Selling Stockholders shall then
be under no further liability to any Underwriter in respect of the Shares not so
delivered except as provided in Sections 6 and 8 hereof.

     12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives; and in all dealings with any Selling Stockholder hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Stockholder made or given by any
or all of the Attorneys-in-Fact for such Selling Stockholder.

     Prior to the filing of any Registration Statement or the Prospectus or any
amendment or supplement thereto, the Company shall deliver or cause to be
delivered to the Selling Stockholders and their respective counsel drafts of the
documents to be filed. The information in such documents as it relates to, or as
it includes information that relates to, any Selling Stockholder shall be deemed
information furnished in writing to the Company by such Selling Stockholder
expressly for use therein if such Selling Stockholder shall approve it or if
such Selling Stockholder shall not have objected in writing to such information
within 10 days after receiving such documents.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; if to any Selling Stockholder shall be delivered or sent by mail,
telex or facsimile transmission to counsel for such Selling Stockholder at its
address set forth in Schedule II hereto; and if to the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of the
Company set forth in the Registration Statement, Attention: Secretary, with a
copy to Thomas A. Cole, Sidley & Austin, One First National Plaza, Chicago,
Illinois 60603; provided, however, that any notice to an Underwriter pursuant to
Section 8(d) hereof shall be delivered or sent by mail, telex or facsimile
transmission to such Underwriter at its address set forth in its Underwriters'
Questionnaire or telex constituting such Questionnaire, which address will be
supplied to the Company or the Selling Stockholders by you on request. Any such
statements, requests, notices or agreements shall take effect upon receipt
thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters,

                                       22

 
the Company and the Selling Stockholders and, to the extent provided in Sections
8 and 10 hereof, the officers and directors of the Company and each person who
controls the Company, any Selling Stockholder or any Underwriter, and their
respective heirs, executors, administrators, successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement. No purchaser of any of the Shares from any Underwriter shall be
deemed a successor or assign by reason merely of such purchase.

     14.  Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15.  This Agreement shall be governed by and construed in accordance with
the laws of the State of New York. Each Selling Stockholder irrevocably submits
to the non-exclusive in personam jurisdiction of any state or federal court
sitting in the Borough of Manhattan, The City of New York, over any suit, action
or proceeding arising out of or relating to this Agreement. To the fullest
extent it may effectively do so under applicable law, each Selling Stockholder
irrevocably waives and agrees not to assert, by way of motion, as a defense or
otherwise, any claim that it is not subject to the in personam jurisdiction of
such court, any objection that it may now or thereafter have to the laying of
venue of any such suit, action or proceeding brought in any such court and any
claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum. Each of the Selling Stockholders agrees,
to the fullest extent it may do so under applicable law, that a final judgment
in any such suit, action or proceeding brought in any such court shall be
conclusive and binding upon such party subject to rights of appeal, and may be
enforced in the courts of the United States or any state thereof by suit upon
such judgment. Each of the Selling Stockholders hereby agrees that service of
all writs, process and summonses in any such suit, action or proceeding may be
made upon the Process Agent set forth with respect to such Selling Stockholder
on Schedule II, and each of the Selling Stockholders hereby irrevocably appoints
such Process Agent his or her true and lawful attorney-in-fact in his or her
name, place and stead to accept such service of any and all such writs, process
and summonses, and agrees that the failure of such Process Agent to give any
notice of any such service of process to such Selling Stockholder shall not
impair or affect the validity of such service or of any judgment based thereon.

     16.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us eight counterparts hereof, and upon the acceptance hereof by you,
on behalf of each of the Underwriters, this letter and such acceptance hereof
shall constitute a binding agreement among each of the Underwriters, the Company
and each of the Selling Stockholders. It is understood that your acceptance of
this letter on behalf of each of the Underwriters is pursuant to the authority
set forth in a form of Agreement Among Underwriters, the form of which shall be

thereof.
