                             UNDERWRITING AGREEMENT

                                                                  April __, 2002

Credit Suisse First Boston Corporation
Deutsche Bank Securities Inc.,
  As Representatives of the Several Underwriters,
    c/o Credit Suisse First Boston Corporation,
         Eleven Madison Avenue,
           New York, N.Y. 10010-3629

Dear Sirs:

         1. Introductory. Yellow Corporation, a Delaware corporation
("COMPANY"), proposes to issue and sell 3,400,000 shares ("FIRM SECURITIES") of
its common stock, $1.00 par value per share ("SECURITIES") and also proposes to
issue and sell to the Underwriters, at the option of the Underwriters, an
aggregate of not more than 510,000 additional shares ("OPTIONAL SECURITIES") of
its Securities as set forth below. The Firm Securities and the Optional
Securities are herein collectively called the "OFFERED SECURITIES". The Company
hereby agrees with the several Underwriters named in Schedule A hereto
("UNDERWRITERS") as follows:

         2. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, the several Underwriters that:

                  (a) A registration statement (No. 333-84314) relating to the
         Offered Securities, including a form of prospectus, has been filed with
         the Securities and Exchange Commission ("COMMISSION") and either (i)
         has been declared effective under the Securities Act of 1933 ("ACT")
         and is not proposed to be amended or (ii) is proposed to be amended by
         amendment or post-effective amendment. If such registration statement
         ("INITIAL REGISTRATION STATEMENT") has been declared effective, either
         (i) an additional registration statement ("ADDITIONAL REGISTRATION
         STATEMENT") relating to the Offered Securities may have been filed with
         the Commission pursuant to Rule 462(b) ("RULE 462(B)") under the Act
         and, if so filed, has become effective upon filing pursuant to such
         Rule and the Offered Securities all have been duly registered under the
         Act pursuant to the initial registration statement and, if applicable,
         the additional registration statement or (ii) such an additional
         registration statement is proposed to be filed with the Commission
         pursuant to Rule 462(b) and will become effective upon filing pursuant
         to such Rule and upon such filing the Offered Securities will all have
         been duly registered under the Act

         pursuant to the initial registration statement and such additional
         registration statement. If the Company does not propose to amend the
         initial registration statement or if an additional registration
         statement has been filed and the Company does not propose to amend it,
         and if any post-effective amendment to either such registration
         statement has been filed with the Commission prior to the execution and
         delivery of this Agreement, the most recent amendment (if any) to each
         such registration statement has been declared effective by the
         Commission or has become effective upon filing pursuant to Rule 462(c)
         ("RULE 462(C)") under the Act or, in the case of the additional
         registration statement, Rule 462(b). For purposes of this Agreement,
         "EFFECTIVE TIME" with respect to the initial registration statement or,
         if filed prior to the execution and delivery of this Agreement, the
         additional registration statement means (i) if the Company has advised
         the Representatives that it does not propose to amend such registration
         statement, the date and time as of which such registration statement,
         or the most recent post-effective amendment thereto (if any) filed
         prior to the execution and delivery of this Agreement, was declared
         effective by the Commission or has become effective upon filing
         pursuant to Rule 462(c), or (ii) if the Company has advised the
         Representatives that it proposes to file an amendment or post-effective
         amendment to such registration statement, the date and time as of which
         such registration statement, as amended by such amendment or
         post-effective amendment, as the case may be, is declared effective by
         the Commission. If an additional registration statement has not been
         filed prior to the execution and delivery of this Agreement but the
         Company has advised the Representatives that it proposes to file one,
         "EFFECTIVE TIME" with respect to such additional registration statement
         means the date and time as of which such registration statement is
         filed and becomes effective pursuant to Rule 462(b). "EFFECTIVE DATE"
         with respect to the initial registration statement or the additional
         registration statement (if any) means the date of the Effective Time
         thereof. The initial registration statement, as amended at its
         Effective Time, including all material incorporated by reference
         therein, including all information contained in the additional
         registration statement (if any) and deemed to be a part of the initial
         registration statement as of the Effective Time of the additional
         registration statement pursuant to the General Instructions of the Form
         on which it is filed and including all information (if any) deemed to
         be a part of the initial registration statement as of its Effective
         Time pursuant to Rule 430A(b) ("RULE 430A(B)") under the Act, is
         hereinafter referred to as the "INITIAL REGISTRATION STATEMENT". The
         additional registration statement, as amended at its Effective Time,
         including the contents of the initial registration statement
         incorporated by reference therein and including all information (if
         any) deemed to be a part of the additional registration statement as of
         its Effective Time pursuant to Rule 430A(b), is hereinafter referred to
         as the "ADDITIONAL REGISTRATION STATEMENT". The Initial Registration
         Statement and the Additional Registration Statement are herein referred
         to collectively as the "REGISTRATION STATEMENTS" and individually as a
         "REGISTRATION STATEMENT". The form of prospectus relating to the
         Offered Securities, as first filed with the Commission pursuant to and
         in accordance with Rule 424(b) ("RULE 424(B)") under the Act or (if no
         such filing is required) as included in a Registration Statement,
         including all material incorporated by reference in such prospectus, is
         hereinafter referred to as the "PROSPECTUS". No document has been or
         will be prepared or distributed in reliance on Rule 434 under the Act.


                                       2

                  (b) If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement: (i)
         on the Effective Date of the Initial Registration Statement, the
         Initial Registration Statement conformed in all respects to the
         requirements of the Act and the rules and regulations of the Commission
         ("RULES AND REGULATIONS") and did not include any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading,
         (ii) on the Effective Date of the Additional Registration Statement (if
         any), each Registration Statement conformed, or will conform, in all
         respects to the requirements of the Act and the Rules and Regulations
         and did not include, or will not include, any untrue statement of a
         material fact and did not omit, or will not omit, to state any material
         fact required to be stated therein or necessary to make the statements
         therein not misleading and (iii) on the date of this Agreement, the
         Initial Registration Statement and, if the Effective Time of the
         Additional Registration Statement is prior to the execution and
         delivery of this Agreement, the Additional Registration Statement each
         conforms, and at the time of filing of the Prospectus pursuant to Rule
         424(b) or (if no such filing is required) at the Effective Date of the
         Additional Registration Statement in which the Prospectus is included,
         each Registration Statement and the Prospectus will conform, in all
         respects to the requirements of the Act and the Rules and Regulations,
         and neither of such documents includes, or will include, any untrue
         statement of a material fact or omits, or will omit, to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading. If the Effective Time of the Initial
         Registration Statement is subsequent to the execution and delivery of
         this Agreement: on the Effective Date of the Initial Registration
         Statement, the Initial Registration Statement and the Prospectus will
         conform in all respects to the requirements of the Act and the Rules
         and Regulations, neither of such documents will include any untrue
         statement of a material fact or will omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, and no Additional Registration Statement has
         been or will be filed. The two preceding sentences do not apply to
         statements in or omissions from a Registration Statement or the
         Prospectus based upon written information furnished to the Company by
         any Underwriter through the Representatives specifically for use
         therein, it being understood and agreed that the only such information
         is that described as such in Section 7(b) hereof.

                  (c) The Company has been duly incorporated and is an existing
         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 the
         Company is duly qualified to do business as a foreign corporation in
         good standing in all other jurisdictions in which its ownership or
         lease of property or the conduct of its business requires such
         qualification.

                  (d) Each subsidiary of the Company has been duly incorporated
         and is an existing corporation in good standing under the laws of the
         jurisdiction of its incorporation, with power and authority (corporate
         and other) to own its properties and conduct its business as described
         in the Prospectus; and each subsidiary of the Company is duly qualified
         to do business as a foreign corporation in good standing in all other
         jurisdictions in which its ownership or lease of property or the
         conduct of its business requires such qualification; all of the issued
         and outstanding capital stock of each subsidiary of the Company has
         been duly authorized and validly issued and is fully


                                       3

         paid and nonassessable; and the capital stock of each subsidiary owned
         by the Company, directly or through subsidiaries, is owned free from
         liens, encumbrances and defects.

                  (e) The Offered Securities and all other outstanding shares of
         capital stock of the Company have been duly authorized; all outstanding
         shares of capital stock of the Company are, and, when the Offered
         Securities have been delivered and paid for in accordance with this
         Agreement on each Closing Date (as defined below), such Offered
         Securities will have been, validly issued, fully paid and nonassessable
         and will conform to the description thereof contained in the
         Prospectus; and the stockholders of the Company have no preemptive
         rights with respect to the Securities.

                  (f) Except as disclosed in the Prospectus, there are no
         contracts, agreements or understandings between the Company and any
         person that would give rise to a valid claim against the Company or any
         Underwriter for a brokerage commission, finder's fee or other like
         payment in connection with this offering.

                  (g) There are no contracts, agreements or understandings
         between the Company and any person granting such person the right to
         require the Company to file a registration statement under the Act with
         respect to any securities of the Company owned or to be owned by such
         person or to require the Company to include such securities in the
         securities registered pursuant to a Registration Statement or in any
         securities being registered pursuant to any other registration
         statement filed by the Company under the Act.

                  (h) The Offered Securities have been approved for listing on
         the Nasdaq Stock Market's National Market subject to notice of
         issuance.

                  (i) No consent, approval, authorization, or order of, or
         filing with, any governmental agency or body or any court is required
         for the consummation of the transactions contemplated by this Agreement
         in connection with the issuance and sale of the Offered Securities by
         the Company, except such as have been obtained and made under the Act
         and such as may be required under state securities laws.

                  (j) The execution, delivery and performance of this Agreement,
         and the issuance and sale of the Offered Securities will not result in
         a breach or violation of any of the terms and provisions of, or
         constitute a default under, (i) any statute, any rule, regulation or
         order of any governmental agency or body or any court, domestic or
         foreign, having jurisdiction over the Company or any subsidiary of the
         Company or any of their properties, (ii) any agreement or instrument to
         which the Company or any such subsidiary is a party or by which the
         Company or any such subsidiary is bound or to which any of the
         properties of the Company or any such subsidiary is subject, or (iii)
         the charter or by-laws of the Company or any such subsidiary, except
         where a breach, violation or default of the type specified in clauses
         (i) and (ii) would not reasonably be expected to have, individually or
         in the aggregate, a Material Adverse Effect (as defined herein). The
         Company has full power and authority to authorize, issue and sell the
         Offered Securities as contemplated by this Agreement.


                                       4

                  (k) This Agreement has been duly authorized, executed and
         delivered by the Company.

                  (l) Except as disclosed in the Prospectus, the Company and its
         subsidiaries have good and marketable title to all material real
         properties and all other material properties and assets owned by them,
         in each case free from liens, encumbrances and defects that would
         materially affect the value thereof or materially interfere with the
         use made or to be made thereof by them; and except as disclosed in the
         Prospectus, the Company and its subsidiaries hold any leased real or
         personal property under valid and enforceable leases with no exceptions
         that would materially interfere with the use made or to be made thereof
         by them.

                  (m) The Company and its subsidiaries possess adequate
         certificates, authorities or permits issued by appropriate governmental
         agencies or bodies necessary to conduct the business now operated by
         them and have not received any notice of proceedings relating to the
         revocation or modification of any such certificate, authority or permit
         that, if determined adversely to the Company or any of its
         subsidiaries, would reasonably be expected to, individually or in the
         aggregate, have a Material Adverse Effect.

                  (n) Except as disclosed in the Prospectus, no labor dispute
         with the employees of the Company or any subsidiary exists or, to the
         knowledge of the Company, is imminent that would reasonably be expected
         to have a Material Adverse Effect.

                  (o) The Company and its subsidiaries own, possess or can
         acquire on reasonable terms, adequate trademarks, trade names and other
         rights to inventions, know-how, patents, copyrights, confidential
         information and other intellectual property (collectively,
         "INTELLECTUAL PROPERTY RIGHTS") necessary to conduct the business now
         operated by them and have not received any notice of infringement of or
         conflict with asserted rights of others with respect to any
         intellectual property rights that, if determined adversely to the
         Company or any of its subsidiaries, would individually or in the
         aggregate have a material adverse effect on the condition (financial or
         other), business, properties or results of operations of the Company
         and its subsidiaries taken as a whole ("MATERIAL ADVERSE EFFECT").

                  (p) Except as disclosed in the Prospectus, neither the Company
         nor any of its subsidiaries is in violation of any statute, any rule,
         regulation, decision or order of any governmental agency or body or any
         court, domestic or foreign, relating to the use, disposal or release of
         hazardous or toxic substances or relating to the protection or
         restoration of the environment or human exposure to hazardous or toxic
         substances (collectively, "ENVIRONMENTAL LAWS"), owns or operates any
         real property contaminated with any substance that is subject to any
         environmental laws, is liable for any off-site disposal or
         contamination pursuant to any environmental laws, or is subject to any
         claim relating to any environmental laws, which violation,
         contamination, liability or claim would individually or in the
         aggregate have a Material Adverse Effect; and the Company is not aware
         of any pending investigation which might lead to such a claim.


                                       5

                  (q) Except as disclosed in the Prospectus, there are no
         pending actions, suits or proceedings against or affecting the Company,
         any of its subsidiaries or any of their respective properties that, if
         determined adversely to the Company or any of its subsidiaries, would
         individually or in the aggregate have a Material Adverse Effect, or
         would materially and adversely affect the ability of the Company to
         perform its obligations under this Agreement; and, to the Company's
         knowledge, no such actions, suits or proceedings have been threatened
         or contemplated.

                  (r) The financial statements included in each Registration
         Statement and the Prospectus present fairly the financial position of
         the Company and its consolidated subsidiaries as of the dates shown and
         their results of operations and cash flows for the periods shown, and
         such financial statements have been prepared in conformity with the
         generally accepted accounting principles in the United States applied
         on a consistent basis; the schedules included in each Registration
         Statement present fairly the information required to be stated therein;
         and the assumptions used in preparing the pro forma financial
         statements included in each Registration Statement and the Prospectus
         provide a reasonable basis for presenting the significant effects
         directly attributable to the transactions or events described therein,
         the related pro forma adjustments give appropriate effect to those
         assumptions, and the pro forma columns therein reflect the proper
         application of those adjustments to the corresponding historical
         financial statement amounts.

                  (s) Except as disclosed in the Prospectus, since the date of
         the latest audited financial statements included in the Prospectus
         there has been no material adverse change, nor any development or event
         involving a prospective material adverse change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and its subsidiaries taken as a whole, and, except as
         disclosed in or contemplated by the Prospectus, there has been no
         dividend or distribution of any kind declared, paid or made by the
         Company on any class of its capital stock.

                  (t) The Company is subject to the reporting requirements of
         either Section 13 or Section 15(d) of the Securities Exchange Act of
         1934 and files reports with the Commission on the Electronic Data
         Gathering, Analysis, and Retrieval (EDGAR) system.

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

         3. Purchase, Sale and Delivery of Offered Securities. On the basis of
the representations, warranties and agreements herein contained, but subject to
the terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of $[___] per share, the respective
numbers of shares of Firm Securities set forth opposite the names of the
Underwriters in Schedule A hereto.

         The Company will deliver the Firm Securities to the Representatives for
the accounts of the Underwriters, against payment of the purchase price in
Federal (same day) funds by wire transfer to an


                                       6

account at a bank acceptable to Credit Suisse First Boston Corporation ("CSFBC")
drawn to the order of Yellow Corporation at the office of Cahill Gordon &
Reindel, at 10:00 A.M., New York time, on [April __], 2002, or at such other
time not later than seven full business days thereafter as CSFBC and the Company
determine, such time being herein referred to as the "FIRST CLOSING DATE". For
purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the First
Closing Date (if later than the otherwise applicable settlement date) shall be
the settlement date for payment of funds and delivery of securities for all the
Offered Securities sold pursuant to the offering. The certificates for the Firm
Securities so to be delivered will be in definitive form, in such denominations
and registered in such names as CSFBC requests and will be made available for
checking and packaging at least 24 hours prior to the First Closing Date.

         In addition, upon written notice from CSFBC given to the Company from
time to time not more than 30 days subsequent to the date of the Prospectus, the
Underwriters may purchase all or less than all of the Optional Securities at the
purchase price per Security to be paid for the Firm Securities. The Company
agrees to sell to the Underwriters the number of shares of Optional Securities
specified in such notice and the Underwriters agree, severally and not jointly,
to purchase such Optional Securities. Such Optional Securities shall be
purchased for the account of each Underwriter in the same proportion as the
number of shares of Firm Securities set forth opposite such Underwriter's name
bears to the total number of shares of Firm Securities (subject to adjustment by
CSFBC to eliminate fractions) and may be purchased by the Underwriters only for
the purpose of covering over-allotments made in connection with the sale of the
Firm Securities. No Optional Securities shall be sold or delivered unless the
Firm Securities previously have been, or simultaneously are, sold and delivered.
The right to purchase the Optional Securities or any portion thereof may be
exercised from time to time and to the extent not previously exercised may be
surrendered and terminated at any time upon notice by CSFBC to the Company.

         Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "OPTIONAL CLOSING DATE", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "CLOSING DATE"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase Optional Securities is given. The Company will deliver the
Optional Securities being purchased on each Optional Closing Date to the
Representatives for the accounts of the several Underwriters against payment of
the purchase price in Federal (same day) funds by official bank check or checks
or wire transfer to an account at a bank acceptable to CSFBC drawn to the order
of Yellow Corporation, at the office of Cahill Gordon & Reindel. The
certificates for the Optional Securities being purchased on each Optional
Closing Date will be in definitive form, in such denominations and registered in
such names as CSFBC requests upon reasonable notice prior to such Optional
Closing Date and will be made available for checking and packaging at the above
office of Cahill Gordon & Reindel at a reasonable time in advance of such
Optional Closing Date.

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

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

                  (a) If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement, the
         Company will file the Prospectus with the Commission pursuant to and in
         accordance with subparagraph (1) (or, if applicable and if consented to
         by CSFBC, subparagraph (4)) of Rule 424(b) not later than the earlier
         of (A) the second business day following the execution and delivery of
         this Agreement or (B) the fifteenth business day after the Effective
         Date of the Initial Registration Statement.

         The Company will advise CSFBC promptly of any such filing pursuant to
         Rule 424(b). If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement and
         an additional registration statement is necessary to register a portion
         of the Offered Securities under the Act but the Effective Time thereof
         has not occurred as of such execution and delivery, the Company will
         file the additional registration statement or, if filed, will file a
         post-effective amendment thereto with the Commission pursuant to and in
         accordance with Rule 462(b) on or prior to 10:00 P.M., New York time,
         on the date of this Agreement or, if earlier, on or prior to the time
         the Prospectus is printed and distributed to any Underwriter, or will
         make such filing at such later date as shall have been consented to by
         CSFBC.

                  (b) The Company will advise CSFBC promptly of any proposal to
         amend or supplement the initial or any additional registration
         statement as filed or the related prospectus or the Initial
         Registration Statement, the Additional Registration Statement (if any)
         or the Prospectus and will not effect such amendment or supplementation
         without CSFBC's consent; and the Company will also advise CSFBC
         promptly of the effectiveness of each Registration Statement (if its
         Effective Time is subsequent to the execution and delivery of this
         Agreement) and of any amendment or supplementation of a Registration
         Statement or the Prospectus and of the institution by the Commission of
         any stop order proceedings in respect of a Registration Statement and
         will use its best efforts to prevent the issuance of any such stop
         order and to obtain as soon as possible its lifting, if issued.

                  (c) If, at any time when a prospectus relating to the Offered
         Securities is required to be delivered under the Act in connection with
         sales by any Underwriter or dealer, any event occurs as a result of
         which the Prospectus as then amended or supplemented would include an
         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 is
         necessary at any time to amend the Prospectus to comply with the Act,
         the Company will promptly notify CSFBC of such event and will promptly
         prepare and file with the Commission, at its own expense, an amendment
         or supplement which will correct such statement or omission or an
         amendment which will effect such compliance. Neither CSFBC's consent
         to, nor the Underwriters' delivery of, any such amendment or supplement
         shall constitute a waiver of any of the conditions set forth in Section
         6.

                  (d) As soon as practicable, but not later than the
         Availability Date (as defined below), the Company will make generally
         available to its securityholders an earnings statement covering a
         period of at least 12 months beginning after the Effective Date of the
         Initial Registration Statement (or, if later, the Effective Date of the
         Additional Registration Statement) which will satisfy the provisions of
         Section 11(a) of the Act. For the purpose of the preceding


                                       8

         sentence, "AVAILABILITY DATE" means the 45th day after the end of the
         fourth fiscal quarter following the fiscal quarter that includes such
         Effective Date, except that, if such fourth fiscal quarter is the last
         quarter of the Company's fiscal year, "AVAILABILITY DATE" means the
         90th day after the end of such fourth fiscal quarter.

                  (e) The Company will furnish to the Representatives copies of
         each Registration Statement (3 of which will be signed and will include
         all exhibits), each related preliminary prospectus, and, so long as a
         prospectus relating to the Offered Securities is required to be
         delivered under the Act in connection with sales by any Underwriter or
         dealer, the Prospectus and all amendments and supplements to such
         documents, in each case in such quantities as CSFBC requests. The
         Prospectus shall be so furnished on or prior to 3:00 P.M., New York
         time, on the business day following the later of the execution and
         delivery of this Agreement or the Effective Time of the Initial
         Registration Statement. All other documents shall be so furnished as
         soon as available. The Company will pay the expenses of printing and
         distributing to the Underwriters all such documents.

                  (f) The Company will arrange for the qualification of the
         Offered Securities for sale under the laws of such jurisdictions as
         CSFBC designates and will continue such qualifications in effect so
         long as required for the distribution.

                  (g) The Company will pay all expenses incident to the
         performance of its obligations under this Agreement, for any filing
         fees and other expenses (including fees and disbursements of counsel)
         incurred in connection with qualification of the Offered Securities for
         sale, for the filing fee incident to the review by the National
         Association of Securities Dealers, Inc. of the Offered Securities, for
         any travel expenses of the Company's officers and employees and any
         other expenses of the Company in connection with attending or hosting
         meetings with prospective purchasers of the Offered Securities and for
         expenses incurred in distributing preliminary prospectuses and the
         Prospectus (including any amendments and supplements thereto) to the
         Underwriters.

                  (h) For a period of 90 days after the date of the initial
         public offering of the Offered Securities, the Company will not offer,
         sell, contract to sell, pledge or otherwise dispose of, directly or
         indirectly, or file with the Commission a registration statement under
         the Act relating to, any additional shares of its Securities or
         securities convertible into or exchangeable or exercisable for any
         shares of its Securities, or publicly disclose the intention to make
         any such offer, sale, pledge, disposition or filing, without the prior
         written consent of CSFBC, except grants of employee stock options
         pursuant to the terms of a plan in effect on the date hereof, issuances
         of Securities pursuant to the exercise of such options or the exercise
         of any other employee stock options outstanding on the date hereof.
         Notwithstanding the foregoing, nothing in this Section 5(h) shall
         prevent the Company from distributing to its stockholders all of the
         stock of its wholly owned subsidiary SCS Transportation, Inc.

         6. Conditions of the Obligations of the Underwriters. The obligations
of the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the


                                       9

representations and warranties on the part of the Company herein, to the
accuracy of the statements of Company officers made pursuant to the provisions
hereof, to the performance by the Company of its obligations hereunder and to
the following additional conditions precedent:

                  (a) The Representatives shall have received a letter, dated
         the date of delivery thereof (which, if the Effective Time of the
         Initial Registration Statement is prior to the execution and delivery
         of this Agreement, shall be on or prior to the date of this Agreement
         or, if the Effective Time of the Initial Registration Statement is
         subsequent to the execution and delivery of this Agreement, shall be
         prior to the filing of the amendment or post-effective amendment to the
         registration statement to be filed shortly prior to such Effective
         Time), of Arthur Andersen LLP confirming that they are independent
         public accountants within the meaning of the Act and the applicable
         published Rules and Regulations thereunder and stating to the effect
         that:

                           (i) in their opinion the financial statements and
                  schedules examined by them and included in the Registration
                  Statements comply as to form in all material respects with the
                  applicable accounting requirements of the Act and the related
                  published Rules and Regulations;

                           (ii) they have performed the procedures specified by
                  the American Institute of Certified Public Accountants for a
                  review of interim financial information as described in
                  Statement of Auditing Standards No. 71, Interim Financial
                  Information, on the unaudited financial statements included in
                  the Registration Statements;

                           (iii) on the basis of the review referred to in
                  clause (ii) above, a reading of the latest available interim
                  financial statements of the Company, inquiries of officials of
                  the Company who have responsibility for financial and
                  accounting matters and other specified procedures, nothing
                  came to their attention that caused them to believe that:

                                    (A) the unaudited financial statements
                           included in the Registration Statements do not comply
                           as to form in all material respects with the
                           applicable accounting requirements of the Act and the
                           related published Rules and Regulations or any
                           material modifications should be made to such
                           unaudited financial statements for them to be in
                           conformity with generally accepted accounting
                           principles;

                                    (B) the unaudited consolidated net operating
                           income, net income and net income per share amounts
                           for the 3 month periods ended March 31, 2002 and
                           March 31, 2001 included in the Prospectus do not
                           agree with the amounts set forth in the unaudited
                           consolidated financial statements for those same
                           periods or were not determined on a basis
                           substantially consistent with that of the
                           corresponding amounts in the audited statements of
                           income;

                                    (C) at the date of the latest available
                           balance sheet read by such accountants, or at a
                           subsequent specified date not more than three
                           business days prior to the date of this Agreement,
                           there was any change in the capital stock or


                                       10

                           any increase in short-term indebtedness or long-term
                           debt of the Company and its consolidated subsidiaries
                           or, at the date of the latest available balance sheet
                           read by such accountants, there was any decrease in
                           consolidated net current assets or net assets, as
                           compared with amounts shown on the latest balance
                           sheet included in the Prospectus;

                                    (D) for the period from the closing date of
                           the latest income statement included in the
                           Prospectus to the closing date of the latest
                           available income statement read by such accountants
                           there were any decreases, as compared with the
                           corresponding period of the previous year and with
                           the period of corresponding length ended the date of
                           the latest income statement included in the
                           Prospectus, in consolidated net operating income, or
                           in the total or per share amounts of consolidated
                           income or net income; or

                                    (E) (i) the pro forma financial information
                           does not comply as to form in all material respects
                           with the applicable accounting requirements of the
                           Act and the Rules and Regulations, (ii) the pro forma
                           adjustments have not been properly applied to the
                           historical amounts in the compilation of those
                           statements, (iii) the methods followed in compiling
                           the pro forma financial information were not proper
                           for such purpose, or (iv) the pro forma adjustments
                           with respect to the pro forma financial information
                           were not appropriate adjustments,

                  except in all cases set forth in clauses (C) and (D) above for
                  changes, increases or decreases which the Prospectus discloses
                  have occurred or may occur or which are described in such
                  letter;

                           (iv) they have compared specified dollar amounts (or
                  percentages derived from such dollar amounts) and other
                  financial information contained in the Registration Statements
                  (in each case to the extent that such dollar amounts,
                  percentages and other financial information are derived from
                  the general accounting records of the Company and its
                  subsidiaries subject to the internal controls of the Company's
                  accounting system or are derived directly from such records by
                  analysis or computation) with the results obtained from
                  inquiries, a reading of such general accounting records and
                  other procedures specified in such letter and have found such
                  dollar amounts, percentages and other financial information to
                  be in agreement with such results, except as otherwise
                  specified in such letter; and

         For purposes of this subsection, (i) if the Effective Time of the
         Initial Registration Statement is subsequent to the execution and
         delivery of this Agreement, "Registration Statements" shall mean the
         initial registration statement as proposed to be amended by the
         amendment or post-effective amendment to be filed shortly prior to its
         Effective Time, (ii) if the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement but
         the Effective Time of the Additional Registration is subsequent to such
         execution and delivery, "Registration Statements" shall mean the
         Initial Registration Statement and the additional registration
         statement as proposed to be filed or as proposed to be amended by the
         post-effective


                                       11

         amendment to be filed shortly prior to its Effective Time, and (iii)
         "Prospectus" shall mean the prospectus included in the Registration
         Statements. All financial statements and schedules included in material
         incorporated by reference into the Prospectus shall be deemed included
         in the Registration Statements for purposes of this subsection.

                  (b) If the Effective Time of the Initial Registration
         Statement is not prior to the execution and delivery of this Agreement,
         such Effective Time shall have occurred not later than 10:00 P.M., New
         York time, on the date of this Agreement or such later date as shall
         have been consented to by CSFBC. If the Effective Time of the
         Additional Registration Statement (if any) is not prior to the
         execution and delivery of this Agreement, such Effective Time shall
         have occurred not later than 10:00 P.M., New York time, on the date of
         this Agreement or, if earlier, the time the Prospectus is printed and
         distributed to any Underwriter, or shall have occurred at such later
         date as shall have been consented to by CSFBC. If the Effective Time of
         the Initial Registration Statement is prior to the execution and
         delivery of this Agreement, the Prospectus shall have been filed with
         the Commission in accordance with the Rules and Regulations and Section
         5(a) of this Agreement. Prior to such Closing Date, no stop order
         suspending the effectiveness of a Registration Statement shall have
         been issued and no proceedings for that purpose shall have been
         instituted or, to the knowledge of the Company or the Representatives,
         shall be contemplated by the Commission.

                  (c) Subsequent to the execution and delivery of this
         Agreement, there shall not have occurred (i) any change, or any
         development or event involving a prospective change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and its subsidiaries taken as one enterprise which, in the
         judgment of a majority in interest of the Underwriters including the
         Representatives, is material and adverse and makes it impractical or
         inadvisable to proceed with completion of the public offering or the
         sale of and payment for the Offered Securities; (ii) any downgrading in
         the rating of any debt securities of the Company by any "nationally
         recognized statistical rating organization" (as defined for purposes of
         Rule 436(g) under the Act), or any public announcement that any such
         organization has under surveillance or review its rating of any debt
         securities of the Company (other than an announcement with positive
         implications of a possible upgrading, and no implication of a possible
         downgrading, of such rating); (iii) any change in U.S. or international
         financial, political or economic conditions or currency exchange rates
         or exchange controls as would, in the judgment of a majority in
         interest of the Underwriters including the Representatives, be likely
         to prejudice materially the success of the proposed issue, sale or
         distribution of the Offered Securities, whether in the primary market
         or in respect of dealings in the secondary market; (iv) any material
         suspension or material limitation of trading in securities generally on
         the New York Stock Exchange, or any setting of minimum prices for
         trading on such exchange, or any suspension of trading of any
         securities of the Company on any exchange or in the over-the-counter
         market; (v) any banking moratorium declared by U.S. Federal or New York
         authorities; (vi) any major disruption of settlements of securities or
         clearance services in the United States; or (vii) any attack on,
         outbreak or escalation of hostilities or act of terrorism involving the
         United States, any declaration of war by Congress or any other national
         or international calamity or emergency if, in the judgment of a
         majority in interest of the Underwriters including the Representatives,
         the effect of any such attack, outbreak, escalation, act, declaration,
         calamity or


                                       12

         emergency makes it impractical or inadvisable to proceed with
         completion of the public offering or the sale of and payment for the
         Offered Securities.

                  (d) The Representatives shall have received an opinion, dated
         such Closing Date, of Cahill Gordon & Reindel, counsel for the Company,
         to the effect that:

                           (i) The Company has been duly incorporated and is an
                  existing corporation in good standing under the laws of the
                  State of Delaware, with corporate power and authority to own
                  its properties and conduct its business as described in the
                  Prospectus;

                           (ii) No consent, approval, authorization or order of,
                  or filing with, any governmental agency or body or any court
                  is required for the consummation of the transactions
                  contemplated by this Agreement in connection with the issuance
                  or sale of the Offered Securities by the Company, except such
                  as have been obtained and made under the Act and such as may
                  be required under state securities laws or as may be required
                  by the National Association of Securities Dealers, Inc.;

                           (iii) The Initial Registration Statement was declared
                  effective under the Act as of the date and time specified in
                  such opinion, the Additional Registration Statement (if any)
                  was filed and became effective under the Act as of the date
                  and time (if determinable) specified in such opinion, the
                  Prospectus either was filed with the Commission pursuant to
                  the subparagraph of Rule 424(b) specified in such opinion on
                  the date specified therein or was included in the Initial
                  Registration Statement or the Additional Registration
                  Statement (as the case may be), and, to the best of the
                  knowledge of such counsel, no stop order suspending the
                  effectiveness of a Registration Statement or any part thereof
                  has been issued and no proceedings for that purpose have been
                  instituted or are pending or contemplated under the Act, and
                  each Registration Statement and the Prospectus, and each
                  amendment or supplement thereto, as of their respective
                  effective or issue dates, complied as to form in all material
                  respects with the requirements of the Act and the Rules and
                  Regulations; the descriptions in the Registration Statements
                  and Prospectus set forth under the captions "Description of
                  Capital Stock" and "Item 15" of Part II insofar as such
                  descriptions constitute a summary of legal matters or
                  documents, are accurate and fairly present in all material
                  respects the information required to be shown; it being
                  understood that such counsel need express no opinion with
                  respect to the financial statements, including the notes and
                  schedules thereto, or any other financial or statistical data
                  found in or derived from the internal accounting or other
                  records of the Company and its subsidiaries set forth in or
                  incorporated by reference into the Registration Statements or
                  the Prospectus;

                           (iv) The Offered Securities delivered on such Closing
                  Date have been duly authorized and validly issued, are fully
                  paid and nonassessable and conform to the description thereof
                  contained in the Prospectus;

                           (v) The Company has full corporate power and
                  authority to authorize, issue and sell the Offered Securities
                  as contemplated by this Agreement; and


                                       13

                           (vi) This Agreement has been duly authorized,
                  executed and delivered by the Company.

         In giving such opinions, such counsel may limit its opinion to the laws
of the state of New York, the General Corporation Law of the state of Delaware
and the Federal laws of the United States of America, and the matters governed
thereby.

         In addition, such counsel shall include a statement that such counsel
has participated in conferences with officers and other representatives of the
Company, representatives of the independent public accountants of the Company
and representatives of the Underwriters at which the contents of the
Registration Statements and the Prospectus and related matters were discussed;
that given the limitations inherent in the role of outside counsel and the
character of determinations involved in the preparation of the Registration
Statements and the Prospectus, such counsel is not passing upon and does not
assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statements or the Prospectus and have
made no independent check or verification thereof (except to the extent provided
in paragraph 6(d)(iii) above); and that on the basis of the foregoing no facts
have come to the attention of such counsel which lead such counsel to believe
that the Prospectus, as of its date or as of the date hereof, contained or
contains an untrue statement of 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 (it being understood
that such counsel expresses no belief with respect to the financial statements,
including the notes and schedules thereto, or any other financial or statistical
data that is found in or derived from the internal accounting or other records
of the company and its subsidiaries set forth in or incorporated by reference
into the Registration Statements or the Prospectus).

                  (e) The Representatives shall have received an opinion, dated
         such Closing Date, of William F. Martin, Jr., Senior Vice President,
         Legal and Corporate Secretary of the Company, to the effect that:

                           (i) The Company is duly qualified to do business as a
                  foreign corporation in good standing in all other
                  jurisdictions in which its ownership or lease of property or
                  the conduct of its business requires such qualification,
                  except where the failure to be so qualified would not
                  reasonably be expected to, individually or in the aggregate,
                  have a Material Adverse Effect;

                           (ii) Each subsidiary of the Company has been duly
                  incorporated and is an existing corporation in good standing
                  under the laws of the jurisdiction of its incorporation, with
                  power and authority (corporate and other) to own its
                  properties and conduct its business as described in the
                  Prospectus; and each subsidiary of the Company is duly
                  qualified to do business as a foreign corporation in good
                  standing in all other jurisdictions in which its ownership or
                  lease of property or the conduct of its business requires such
                  qualification, except where the failure to be so qualified
                  would not reasonably be expected to, individually or in the
                  aggregate, have a Material Adverse Effect; all of the issued
                  and outstanding capital stock of each subsidiary of the
                  Company has been duly authorized and validly issued and is
                  fully paid and nonassessable; and the


                                       14

                  capital stock of each subsidiary owned by the Company,
                  directly or through subsidiaries, is owned free from liens,
                  encumbrances and defects;

                           (iii) All of the outstanding shares of Common Stock,
                  other than the Offered Securities, have been duly authorized
                  and validly issued, are fully paid and nonassessable and
                  conform to the description thereof contained in the
                  Prospectus; and the stockholders of the Company have no
                  preemptive rights with respect to the Securities;

                           (iv) The execution, delivery and performance of this
                  Agreement and the issuance and sale of the Offered Securities
                  will not result in a breach or violation of any of the terms
                  and provisions of, or constitute a default under, (A) any
                  statute, any rule, regulation or order of any governmental
                  agency or body or any court having jurisdiction over the
                  Company or any subsidiary of the Company or any of their
                  properties, (B) any agreement or instrument to which the
                  Company or any such subsidiary is a party or by which the
                  Company or any such subsidiary is bound or to which any of the
                  properties of the Company or any such subsidiary is subject,
                  or (C) the charter or by-laws of the Company or any such
                  subsidiary except where a breach, violation or default of the
                  type specified in clauses (A) and (B) would not have,
                  individually or in the aggregate, a Material Adverse Effect.

                           (v) There are no contracts, agreements or
                  understandings known to such counsel between the Company and
                  any person granting such person the right to require the
                  Company to file a registration statement under the Act with
                  respect to any securities of the Company owned or to be owned
                  by such person or to require the Company to include such
                  securities in the securities registered pursuant to the
                  Registration Statement or in any securities being registered
                  pursuant to any other registration statement filed by the
                  Company under the Act; and

                           (vi) The descriptions in (A) the Registration
                  Statements and Prospectus set forth under the caption
                  "Business-Regulation," (B) the Company's Annual Report on Form
                  10-K for the year ended December 31, 2001, in the eighth to
                  last paragraph under the captions "Item 1(c) Narrative
                  Description of the Business" and "Item 3 Legal Proceedings,"
                  and (C) the Company's Proxy Statement dated March 6, 2002
                  under the caption "Employment Contracts, Change of Control
                  Agreements and Termination of Employment Agreements" insofar
                  as such descriptions constitute a summary of statutes, legal
                  and governmental proceedings and contracts are accurate and
                  fairly present in all material respects the information
                  required to be shown; and such counsel does not know of any
                  legal or governmental proceedings required to be described in
                  a Registration Statement or the Prospectus which are not
                  described as required or of any contracts or documents of a
                  character required to be described in a Registration Statement
                  or the Prospectus or to be filed as exhibits to a Registration
                  Statement which are not described and filed as required.


                                       15

                  (f) The Representatives shall have received from Mayer, Brown,
         Rowe & Maw, counsel for the Underwriters, such opinion or opinions,
         dated such Closing Date, with respect to the incorporation of the
         Company, the validity of the Offered Securities delivered on such
         Closing Date, the Registration Statements, the Prospectus and other
         related matters as the Representatives may 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.

                  (g) The Representatives shall have received a certificate,
         dated such Closing Date, of the President or any Vice President and a
         principal financial or accounting officer of the Company in which such
         officers, to the best of their knowledge after reasonable
         investigation, shall state that: the representations and warranties of
         the Company in this Agreement are true and correct; the Company has
         complied with all agreements and satisfied all conditions on its part
         to be performed or satisfied hereunder at or prior to such Closing
         Date; no stop order suspending the effectiveness of any Registration
         Statement has been issued and no proceedings for that purpose have been
         instituted or are contemplated by the Commission; the Additional
         Registration Statement (if any) satisfying the requirements of
         subparagraphs (1) and (3) of Rule 462(b) was filed pursuant to Rule
         462(b), including payment of the applicable filing fee in accordance
         with Rule 111(a) or (b) under the Act, prior to the time the Prospectus
         was printed and distributed to any Underwriter; and, subsequent to the
         respective dates of the most recent financial statements in the
         Prospectus, there has been no material adverse change, nor any
         development or event involving a prospective material adverse change,
         in the condition (financial or other), business, properties or results
         of operations of the Company and its subsidiaries taken as a whole
         except as set forth in or contemplated by the Prospectus or as
         described in such certificate.

                  (h) The Representatives shall have received a letter, dated
         such Closing Date, of Arthur Andersen LLP which meets the requirements
         of subsection (a) of this Section, except that the specified date
         referred to in such subsection will be a date not more than three days
         prior to such Closing Date for the purposes of this subsection.

The Company will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably
requests. CSFBC may in its sole discretion waive on behalf of the Underwriters
compliance with any conditions to the obligations of the Underwriters hereunder,
whether in respect of an Optional Closing Date or otherwise.

         7. Indemnification and Contribution. The Company will indemnify and
hold harmless each Underwriter, its partners, directors and officers and each
person, if any, who controls such Underwriter within the meaning of Section 15
of the Act, 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 any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement,
the Prospectus, or any amendment or supplement thereto, or any related
preliminary prospectus, 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 loss, claim,
damage, liability or


                                       16

action as such expenses are incurred; 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 an untrue statement or alleged
untrue statement in or omission or alleged omission from any of such documents
in reliance upon and in conformity with written information furnished to the
Company by any Underwriter through the Representatives specifically for use
therein, it being understood and agreed that the only such information furnished
by any Underwriter consists of the information described as such in subsection
(b) below; and provided, further, that with respect to any untrue statement or
alleged untrue statement in or omission or alleged omission from any preliminary
prospectus the foregoing indemnity shall not inure to the benefit of any
Underwriter from whom the person asserting any such losses, claims, damages or
liabilities purchased the Offered Securities concerned, to the extent that a
prospectus relating to such Offered Securities was required to be delivered by
such Underwriter under the Act in connection with such purchase and any such
loss, claim, damage or liability of such Underwriter results from the fact that
there was not sent or given to such person, at or prior to the written
confirmation of the sale of such Offered Securities to such person, a copy of
the Prospectus (exclusive of material incorporated by reference) if the Company
had previously furnished copies thereof to such Underwriter.

                  (a) Each Underwriter will severally and not jointly indemnify
         and hold harmless the Company, its directors and officers and each
         person, if any who controls the Company within the meaning of Section
         15 of the Act, against any losses, claims, damages or liabilities to
         which the Company 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 any untrue statement or
         alleged untrue statement of any material fact contained in any
         Registration Statement, the Prospectus, or any amendment or supplement
         thereto, or any related preliminary prospectus, or arise out of or are
         based upon the omission or the 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 reliance upon and in
         conformity with written information furnished to the Company by such
         Underwriter through the Representatives specifically for use therein,
         and will reimburse any legal or other expenses reasonably incurred by
         the Company in connection with investigating or defending any such
         loss, claim, damage, liability or action as such expenses are incurred,
         it being understood and agreed that the only such information furnished
         by any Underwriter consists of the following information in the
         Prospectus furnished on behalf of each Underwriter: the concession and
         reallowance figures appearing in the fourth paragraph under the caption
         "Underwriting" and the information contained in the tenth and eleventh
         paragraphs under the caption "Underwriting".

                  (b) Promptly after receipt by an indemnified party under this
         Section 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 subsection (a) or (b) above, notify the
         indemnifying party of the commencement thereof; but the omission so to
         notify the indemnifying party will not relieve it from any liability
         which it may have to any indemnified party otherwise than under
         subsection (a) or (b) above. In case any such action is brought against
         any indemnified party and it notifies the indemnifying party of the
         commencement thereof, the indemnifying party will be entitled to
         participate therein and, to the extent that it may wish, jointly with
         any other indemnifying party similarly notified, to assume the defense
         thereof, with counsel reasonably


                                       17

         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 will not be liable to such indemnified party under
         this Section for any legal or other expenses subsequently incurred by
         such indemnified party in connection with the defense thereof other
         than reasonable costs of investigation. No indemnifying party shall,
         without the prior written consent of the indemnified party, effect any
         settlement of any pending or threatened action 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 (i) includes an unconditional release of such indemnified
         party from all liability on any claims that are the subject matter of
         such action 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
         an indemnified party.

                  (c) If the indemnification provided for in this Section is
         unavailable or insufficient to hold harmless an indemnified party under
         subsection (a) or (b) above, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party as a
         result of the losses, claims, damages or liabilities referred to in
         subsection (a) or (b) above (i) in such proportion as is appropriate to
         reflect the relative benefits received by the Company on the one hand
         and the Underwriters on the other from the offering of the Securities
         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 Company 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 as well as any other
         relevant equitable considerations. The relative benefits received by
         the Company 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 bear to
         the total underwriting discounts and commissions received by the
         Underwriters. 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 Underwriters
         and the parties' relative intent, knowledge, access to information and
         opportunity to correct or prevent such untrue statement or omission.
         The amount paid by an indemnified party as a result of the losses,
         claims, damages or liabilities referred to in the first sentence of
         this subsection (d) shall be deemed to include any legal or other
         expenses reasonably incurred by such indemnified party in connection
         with investigating or defending any action or claim which is the
         subject of this subsection (d). Notwithstanding the provisions of this
         subsection (d), no Underwriter shall be required to contribute any
         amount in excess of the amount by which the total price at which the
         Securities 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 (d) to contribute are several in
         proportion to their respective underwriting obligations and not joint.


                                       18

                  (d) The obligations of the Company under this Section shall be
         in addition to any liability which the Company 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 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 director of the Company, to each officer of the Company who has
         signed a Registration Statement and to each person, if any, who
         controls the Company within the meaning of the Act.

         8. Default of Underwriters. If any Underwriter or Underwriters default
in their obligations to purchase Offered Securities hereunder on either the
First or any Optional Closing Date and the aggregate number of shares of Offered
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase does not exceed 10% of the total number of shares of Offered Securities
that the Underwriters are obligated to purchase on such Closing Date, CSFBC may
make arrangements satisfactory to the Company for the purchase of such Offered
Securities by other persons, including any of the Underwriters, but if no such
arrangements are made by such Closing Date, the non-defaulting Underwriters
shall be obligated severally, in proportion to their respective commitments
hereunder, to purchase the Offered Securities that such defaulting Underwriters
agreed but failed to purchase on such Closing Date. If any Underwriter or
Underwriters so default and the aggregate number of shares of Offered Securities
with respect to which such default or defaults occur exceeds 10% of the total
number of shares of Offered Securities that the Underwriters are obligated to
purchase on such Closing Date and arrangements satisfactory to CSFBC and the
Company for the purchase of such Offered Securities by other persons are not
made within 36 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter or the Company, except
as provided in Section 9 (provided that if such default occurs with respect to
Optional Securities after the First Closing Date, this Agreement will not
terminate as to the Firm Securities or any Optional Securities purchased prior
to such termination). As used in this Agreement, the term "Underwriter" includes
any person substituted for an Underwriter under this Section. Nothing herein
will relieve a defaulting Underwriter from liability for its default.

         9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of any Underwriter, the Company or any of their respective representatives,
officers or directors or any controlling person, and will survive delivery of
and payment for the Offered Securities. If this Agreement is terminated pursuant
to Section 8 or if for any reason the purchase of the Offered Securities by the
Underwriters is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Underwriters pursuant to Section 7 shall
remain in effect, and if any Offered Securities have been purchased hereunder
the representations and warranties in Section 2 and all obligations under
Section 5 shall also remain in effect. If the purchase of the Offered Securities
by the Underwriters is not consummated for any reason other than solely because
of the termination of this Agreement pursuant to Section 8 or the occurrence of
any event specified in clause (iii), (iv), (v), (vi) or (vii) of Section 6(c),
the Company will reimburse the Underwriters for all out-of-pocket expenses
(including documented fees and


                                       19

disbursements of counsel) reasonably incurred by them in connection with the
offering of the Offered Securities.

         10. Notices. All communications hereunder will be in writing and, if
sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed
to the Representatives, c/o Credit Suisse First Boston Corporation, Eleven
Madison Avenue, New York, N.Y. 10010-3629, Attention: Transactions Advisory

William F. Martin, Jr.; provided, however, that any notice to an Underwriter
pursuant to Section 7 will be mailed, delivered or telegraphed and confirmed to
such Underwriter.

         11. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

         12. Representation of Underwriters. The Representatives will act for
the several Underwriters in connection with this financing, and any action under
this Agreement taken by the Representatives jointly or by CSFBC will be binding
upon all the Underwriters.

         13. Counterparts. This Agreement may be executed 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 Agreement.

         14. APPLICABLE LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAWS.

         The Company hereby submits to the non-exclusive jurisdiction of the
Federal and state courts in the Borough of Manhattan in The City of New York in
any suit or proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby.
