     Company and its subsidiaries, taken as a whole (a "Material Adverse
     Effect").

     reorganization, insolvency, moratorium or other laws affecting creditors'
     rights generally from time to time in effect and to general principles of

     the securities or Blue Sky laws of the various states in connection with
     the offer and sale of the Shares and except those for which the failure to
     obtain, individually or in the aggregate, would not have a Material Adverse
     Effect.

          (i) There has not occurred any material adverse change, or any
     development involving a prospective material adverse change, in the
     financial condition or in the earnings, business or operations of the
     Company and its subsidiaries, taken as a whole, from that set forth in the
     Final Prospectus (exclusive of any amendments or supplements thereto
     subsequent to the date of this Agreement).

          (j) There are no legal or governmental proceedings pending or, to the

     would not, individually or in the aggregate, have a Material Adverse
     Effect.

          (n) Subsequent to the respective dates as of which information is
     given in the Registration Statement and the Final Prospectus, (i) the
     Company and its subsidiaries have not incurred any material liability or

     property and do not interfere with the use made and proposed to be made of
     such property by the Company and its subsidiaries; and any real property
     and buildings held under lease by the Company and its subsidiaries are held

     procedures), trademarks, service marks and trade names necessary for the
     conduct of the business now operated by them, except where the failure to
     so own, possess or be able to acquire on reasonable terms would not,
     individually or in the aggregate, have a Material Adverse Effect, and
     neither the Company nor any of its subsidiaries has received any notice of
     infringement of or conflict with asserted rights of others with respect to
     any of the foregoing which, individually or in the aggregate, if the

     relating to the revocation or modification of any such certificate,
     authorization or permit which, individually or in the aggregate, if the

     approval, except where such noncompliance with Environmental Laws, failure
     to receive required permits, licenses or other approvals or failure to

     suspension of the qualification of the Securities for sale in any
     jurisdiction or the institution or threatening of any proceeding for such
     purpose. The Company will use its best efforts to prevent the issuance of
     any such stop order or the suspension of any such qualification and, if
     issued, to obtain as soon as possible the withdrawal thereof.

          (b) If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Securities Act, any event occurs as a
     result of which the Final Prospectus as then supplemented would include any
     untrue statement of a material fact or omit to state any material fact
     necessary to make the statements

                                                                              10


     therein in the light of the circumstances under which they were made not
     misleading, or if it shall be necessary to amend the Registration Statement
     or supplement the Final Prospectus to comply with the Securities Act or the
     Exchange Act or the respective rules thereunder, the Company promptly will
     (1) notify the Representatives of such event, (2) prepare and file with the
     Commission, subject to the second sentence of paragraph (a) of this Section
     5, an amendment or supplement which will correct such statement or omission
     or effect such compliance and (3) supply any supplemented Final Prospectus
     to you in such quantities as you may reasonably request.

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

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

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

          (f) The Company will not, without the prior written consent of the
     Representatives, offer, sell, contract to sell, pledge, or otherwise
     dispose of, (or enter into any transaction which is designed to, or might
     reasonably be expected to, result in the disposition (whether by actual
     disposition or effective economic disposition due to cash settlement or
     otherwise) by the Company or any affiliate of the Company or any person in
     privity with the Company or any affiliate of the Company) directly or
     indirectly, including the filing (or participation in the filing) of a
     registration statement with the Commission in respect of, or establish or
     increase a put equivalent position or liquidate or decrease a call
     equivalent position within the meaning of Section 16 of the Exchange Act,
     any debt

                                                                              11


     securities issued or guaranteed by the Company (other than the Securities)
     or publicly announce an intention to effect any such transaction, until the
     Business Day set forth on Schedule I hereto.

          (g) Prior to the date hereof, the Company has not taken, and from the
     date hereof to the Closing Date, the Company will not take, directly or
     indirectly, any action designed to or that would constitute or that might
     reasonably be expected to cause or result in, under the Exchange Act or
     otherwise, stabilization or manipulation of the price of any debt security
     of the Company to facilitate the sale or resale of the Securities.

          6. Conditions to the Obligations of the Underwriters. The obligations
of the Underwriters to purchase the Securities shall be subject to the accuracy
of the representations and warranties on the part of the Company contained
herein as of the Execution Time and the Closing Date, to the performance by the
Company of its obligations hereunder and to the following additional conditions:

          (a) The Final Prospectus, and any supplement thereto, will be filed in
     the manner and within the time period required by Rule 424(b); and no stop
     order suspending the effectiveness of the Registration Statement shall have
     been issued and no proceedings for that purpose shall have been instituted
     or threatened.

          (b) The Company shall have requested and caused Winston & Strawn LLP,
     counsel for the Company, to have furnished to the Representatives their
     opinion, dated the Closing Date and addressed to the Representatives, to
     the effect that:

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

               (ii) the Indenture has been duly authorized, executed and
          delivered by the Company, has been duly qualified under the Trust
          Indenture Act, and, assuming that the Indenture is the valid and
          legally binding obligation of the Trustee, the Indenture constitutes
          the valid and legally binding obligation of the Company, enforceable
          against the Company in accordance with its terms (subject, as to
          enforcement of remedies, to applicable bankruptcy, reorganization,
          insolvency, moratorium or other laws affecting creditors' rights
          generally from time to time in effect and to general principles of
          equity, including, without limitation, concepts of materiality,
          reasonableness, good faith and fair dealing, regardless of whether
          considered in a proceeding in equity or at law); and the Securities
          have been duly authorized by the Company and, when executed by the
          Company and authenticated and issued in accordance with the provisions
          of the Indenture and delivered to and paid for by the Underwriters
          pursuant to this Agreement, will constitute valid and legally binding
          obligations of the Company entitled to the benefits of

                                                                              12


          the Indenture (subject, as to enforcement of remedies, to applicable
          bankruptcy, reorganization, insolvency, moratorium or other laws
          affecting creditors' rights generally from time to time in effect and
          to general principles of equity, including, without limitation,
          concepts of materiality, reasonableness, good faith and fair dealing,
          regardless of whether considered in a proceeding in equity or at law);

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

               (iv) the Registration Statement and the Final Prospectus (except
          for the financial statements and related notes and other financial or
          statistical data included therein or omitted therefrom, as to which
          such counsel need not comment) appear on their face to be responsive
          as to form in all material respects to the requirements of the
          Securities Act and the applicable rules and regulations of the
          Commission thereunder.

               In the course of such counsel's review of the contents of the
          Registration Statement and its participation in the preparation of the
          Final Prospectus and review and discussion of the contents thereof,
          although such counsel has not independently checked or verified, and
          is not passing upon and assumes no responsibility for, the accuracy,
          completeness, or fairness thereof, or otherwise verified the
          statements made therein, as of the Closing Date no facts have come to
          the attention of such counsel that cause such counsel to believe that
          (i) the Registration Statement or the Final Prospectus included
          therein (except for the financial statements and related notes and
          other financial or statistical data included therein or omitted
          therefrom, as to which such counsel need not comment) as of the date
          of this Agreement contained an untrue statement of a material fact or
          omitted to state a material fact required to be stated therein or
          necessary to make the statements therein not misleading or (ii) the
          Final Prospectus (except for the financial statements and related
          notes and other financial or statistical data included therein or
          omitted therefrom, as to which such counsel need not comment) as of
          its date or as of the Closing Date contained or contains an untrue
          statement of a material fact or omitted or omits to state a material
          fact necessary in order to make the statements therein, in the light
          of the circumstances under which they were made, not misleading.

               In rendering such opinion, such counsel may rely, without
          independent verification, as to matters of fact, to the extent they
          deem appropriate, on the representations of the Company contained
          herein and on certificates of responsible officers of the Company and
          public officials. Such opinion will be limited to the laws of the
          State of New York, the

                                                                              13


          federal laws of the United States and the General Corporation Law of
          the State of Delaware, and such counsel will express no opinion as to
          the effect on the matters covered by such opinion of the laws of any
          other jurisdiction. Such opinion may also state that such counsel
          acted as special counsel to the Company in connection with the
          offering of the Securities contemplated hereby and did not act, and
          has not acted, as the Company's regular outside counsel. References to
          the Final Prospectus in this paragraph (b) shall also include any
          supplements thereto at the Closing Date.

          (c) The Underwriters shall have received on the Closing Date an
     opinion of Alan G. Berkshire, Esq., General Counsel to the Company, dated
     the Closing Date, to the effect that:

               (i) the Company has been duly incorporated, is validly existing
          as a corporation in good standing under the laws of the State of
          Delaware, has the corporate power and authority to own its property
          and to conduct its business as described in the Final Prospectus and
          is duly qualified to transact business and is in good standing in each
          jurisdiction in which the conduct of its business or its ownership or
          leasing of property requires such qualification, except to the extent
          that the failure to be so qualified or be in good standing would not
          have a Material Adverse Effect;

               (ii) each Significant Subsidiary of the Company has been duly
          incorporated or formed, is validly existing in good standing under the
          laws of the jurisdiction of its incorporation or formation, has the

          which the conduct of its business or its ownership or leasing of

          Material Adverse Effect;

               (iii) to such counsel's knowledge and other than as set forth in
          the Final Prospectus, there are no legal or governmental proceedings
          pending or threatened to which the Company or any of its subsidiaries
          is a party or to which any of the properties of the Company or any of
          its subsidiaries is subject, which, if determined adversely to the
          Company or any of its subsidiaries, would individually or in the

          counsel's knowledge, none of the Company or its subsidiaries other
          than the Investment Advisory Subsidiaries is required to be
          registered, licensed, or qualified as an investment adviser under the
          Advisers Act and the rules

          and regulation of the Commission promulgated thereunder or under
          applicable state laws, except where any failure to be so registered,
          licensed, or qualified would not have a Material Adverse Effect. To
          such counsel's knowledge, each of the Investment Advisory Subsidiaries
          is in compliance with the Advisers Act and applicable state laws,
          regulations, ordinances and rules applicable to it or its operations
          relating to investment advisory activities except where any failure by
          any such Investment Advisory Subsidiary to comply with any such law,
          regulation, ordinance or rule would not have a Material Adverse
          Effect.

               (v) to the knowledge of such counsel, neither the Company nor any
          Investment Advisory Subsidiary is in breach or violation of or in
          default under any investment advisory contract which would

          qualified as a broker-dealer under the Exchange Act and in each
          Jurisdiction where the conduct of its business requires registration,
          licensing or qualification, except to the extent that the failure to
          be so registered, licensed or qualified would not have a Material
          Adverse Effect. None of the Company or its subsidiaries, other than
          the Broker-Dealer Subsidiary, is required to be registered, licensed
          or qualified as a broker-dealer under the Exchange Act and the rules
          and regulations of the Commission promulgated thereunder or under the
          laws requiring any such registration, licensing or qualification in
          any jurisdiction in which it conducts business, except where any
          failure to be so registered, licensed, or qualified would not have a
          Material Adverse Effect. Each of the Company and the Broker-Dealer
          Subsidiary is in compliance with all laws, regulations, ordinances and
          rules (including those of any self regulatory organizations) as
          applicable to it or its operations relating to broker-dealer
          activities except where any failure to comply with any such law,
          regulation, ordinance or rule would not have, individually or in the
          aggregate, a Material Adverse Effect;

               (vii) except as disclosed in the Final Prospectus, the execution
          and delivery by the Company of, and the performance by the Company of
          its obligations under this Agreement, the Indenture and the
          Securities, will not contravene any provision of applicable law or the
          certificate of incorporation or by-laws of the Company or, to such
          counsel's knowledge, any agreement or other instrument binding upon
          the Company or any of its subsidiaries that is material to the Company
          and its subsidiaries, taken as a whole, or, to such counsel's
          knowledge, any judgment, order or decree of any governmental body,
          agency or court having jurisdiction over the Company or any
          subsidiary, and no consent, approval, authorization or order of, or
          qualification with, any U.S. federal, State of Illinois or State of

                                                                              15


          Delaware governmental body or agency is required for the performance
          by the Company of its obligations under this Agreement, except those
          which have been obtained or made, and as may be required by the
          securities or Blue Sky laws of the various states in connection with
          the offer and sale of the Securities (it being understood that this
          opinion is limited to those consents, approvals, authorizations,
          orders, and qualifications that, in such counsel's experience, are
          normally applicable to transactions of the type contemplated by this
          Agreement); and

               (viii) the Registration Statement and the Final Prospectus
          (except for the financial statements and related notes and other
          financial or statistical data included therein or omitted therefrom,
          as to which such counsel need not comment) appear on their face to be
          responsive as to form in all material respects to the requirements of
          the Securities Act and the applicable rules and regulations of the
          Commission thereunder.

               In the course of such counsel's participation in the preparation
          of the Registration Statement and Final Prospectus and review and
          discussion of the contents thereof, although such counsel has not
          independently checked or verified, and is not passing upon and assumes
          no responsibility for, the accuracy, completeness, or fairness
          thereof, or otherwise verified the statements made therein (it being
          understood that such counsel has prepared and reviewed the disclosures
          included in the Final Prospectus under the caption
          "Business--Regulatory," and incorporated by reference in the Final
          Prospectus under the caption "Legal Proceedings" in the Company's
          Annual Report on Form 10-K for the year ended December 31, 2004 and
          under the caption "Legal Proceedings" in the Company's Quarterly
          Report on Form 10-Q for the three-month period ended June 30, 2005),
          as of the Closing Date no facts have come to the attention of such
          counsel that cause such counsel to believe that (i) the Registration
          Statement or the prospectus included therein (except for the financial
          statements and related notes and other financial or statistical data
          included therein or omitted therefrom, as to which such counsel need
          not comment) on the date the Registration Statement became effective
          and as of the date of this Agreement contained an untrue statement of
          a material fact or omitted to state a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading or (ii) the Final Prospectus (except for the financial
          statements and related notes and other financial or statistical data
          included therein or omitted therefrom, as to which such counsel need
          not comment) as of its date or as of the Closing Date contained or
          contains an untrue statement of a material fact or omitted or omits to
          state a material fact necessary in order to make the statements
          therein, in the light of the circumstances under which they were made,
          not misleading.

                                                                              16


               In rendering such opinion, such counsel may rely, without
          independent verification, (x) as to matters of fact, to the extent he
          deems appropriate, on certificates of responsible officers of the
          Company and public officials, and (y) as to matters involving the
          application of any jurisdiction other than the State of Illinois, the
          federal laws of the United States and the General Corporation Law of
          the State of Delaware, to the extent he deems appropriate and
          specified in such opinion, upon the opinion of other counsel of good
          standing whom he reasonably believes to be reliable and who are
          reasonably satisfactory to counsel for the Underwriters. References to
          the Final Prospectus in this paragraph (c) shall also include any
          supplements thereto at the Closing Date.

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

          (e) The Company shall have furnished to the Representatives a
     certificate of the Company, signed by the President or any Senior Vice
     President and the principal financial or accounting officer of the Company,

     have carefully examined the Registration Statement, the Final Prospectus,
     any supplements to the Final Prospectus and this Agreement and that:

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

               (ii) no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge,
          threatened; and

               (iii) since the date of the most recent financial statements
          included or incorporated by reference in the Final Prospectus
          (exclusive of any supplement thereto), there has been no material
          adverse effect on the condition (financial or otherwise), earnings,
          business or properties of the Company and its subsidiaries, taken as a
          whole, whether or not arising from transactions in the ordinary course
          of business, except as set forth in or contemplated in the Final
          Prospectus (exclusive of any supplement thereto).

                                                                              17


          (f) The Company shall have requested and caused KPMG LLP, independent
     registered public accountants, to have furnished to the Representatives, at
     the Execution Time and at the Closing Date, letters, (which may refer to
     letters previously delivered to one or more of the Representatives), dated
     respectively as of the Execution Time and as of the Closing Date, in form
     and substance satisfactory to the Representatives, confirming that they are
     independent registered public accountants with respect to the Company
     within the meaning of the Securities Act and the applicable rules and
     regulations adopted thereunder by the Commission and the Public Company
     Accounting Oversight Board (United States) (the "PCAOB") and that they have
     performed the procedures specified by the PCAOB for a review of the
     unaudited interim financial information of the Company for the three-month
     periods ended March 31, 2005 and 2004, and the three-month and six-month
     periods ended June 30, 2005 and 2004, in accordance with Statement on
     Auditing Standards No. 100, and stating in effect, except as provided in
     Schedule I hereto, that:

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

               (ii) on the basis of a reading of the latest unaudited financial
          statements made available by the Company and its subsidiaries; their
          limited review, in accordance with the procedures specified by the
          PCAOB for a review of interim financial information as described in
          Statement on Auditing Standards No. 100, of the unaudited condensed
          consolidated financial information for the three-month periods ended
          March 31, 2005 and 2004, and the three-month and six-month periods
          ended June 30, 2005 and 2004; carrying out certain specified
          procedures (but not an examination in accordance with the standards of
          the PCAOB) which would not necessarily reveal matters of significance
          with respect to the comments set forth in such letter; a reading of
          the minutes of the meetings of the directors and compensation and
          audit committees of the Company and its subsidiaries; and inquiries of
          certain officials of the Company who have responsibility for financial
          and accounting matters of the Company and its subsidiaries as to
          transactions and events subsequent to December 31, 2004, nothing came
          to their attention which caused them to believe that:

                    (1) any unaudited condensed consolidated financial
               statements incorporated by reference in the Registration
               Statement and the Final Prospectus do not comply as to form in
               all material respects with applicable accounting requirements of
               the Exchange

                                                                              18


               Act as it applies to Form 10-Q and the related rules and
               regulations adopted by the Commission; or that any material
               modifications should be made to said unaudited financial
               statements for them to be in conformity with generally accepted
               accounting principles;

                    (2) with respect to the period subsequent to June 30, 2005,
               there were any changes, at a specified date not more than five
               days prior to the date of the letter, in the long-term debt of
               the Company and its subsidiaries or in the capital stock or
               consolidated short-term obligations of the Company, or that there
               was any decrease in consolidated net assets or stockholders'
               equity of the Company as compared with the amounts shown on the
               June 30, 2005 consolidated balance sheet incorporated by
               reference in the Registration Statement and the Final Prospectus,
               or for the period from July 1, 2005 to such specified date there
               were any decreases, as compared with the corresponding period in
               the preceding year in the total or per share amounts of income or
               of net income, in consolidated total revenues, income before
               taxes or net income or earnings per common share of the Company
               and its subsidiaries, except in all instances for changes or
               decreases set forth in such letter, in which case the letter
               shall be accompanied by an explanation by the Company as to the
               significance thereof unless said explanation is not deemed
               necessary by the Representatives; and

                    (3) the information included or incorporated by reference in
               the Registration Statement and Final Prospectus in response to
               Regulation S-K, Item 301 (Selected Financial Data) and Item 402
               (Executive Compensation), is not in conformity with the
               applicable disclosure requirements of Regulation S-K.

               (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Registration Statement and the Final Prospectus and in
          Exhibit 12 to the Registration Statement, including the information
          set forth under the captions "Prospectus Supplement Summary", "Risk
          Factors", "Use of Proceeds", "Capitalization", "Ratio of Earnings to
          Fixed Charges", "Selected Consolidated Financial Data", "Management's
          Discussion and Analysis of Financial Condition and Results of
          Operations" and "Business" in the Final Prospectus, the information
          included or incorporated by reference in Items 1, 5, 6, 7 and 12 of
          the Company's Annual Report on Form 10-K, incorporated by reference in
          the Registration Statement and the Final

                                                                              19


          Prospectus, and the information included in the "Management's
          Discussion and Analysis of Financial Condition and Results of
          Operations" incorporated by reference in the Company's Quarterly
          Reports on Form 10-Q, incorporated by reference in the Registration
          Statement and the Final Prospectus, agrees with the accounting records
          of the Company and its subsidiaries, excluding any questions of legal
          interpretation.

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

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

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

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

          (j) The Company shall use the proceeds of the offering of the
     Securities to repay outstanding borrowings under the $750 million Bridge
     Credit Agreement dated as of April 1, 2005 among the Company, various
     financial institutions party thereto, Citicorp North America, Inc., as
     administrative agent and Citigroup Global Markets, Inc., as arranger.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled when and as provided in this Agreement, or if any of the opinions
and

                                                                              20


certificates mentioned above or elsewhere in this Agreement shall not be
reasonably satisfactory in form and substance to the Representatives and counsel
for the Underwriters, this Agreement and all obligations of the Underwriters
hereunder may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancellation shall be given to the Company in
writing or by telephone or facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be
delivered at the office of Davis Polk & Wardwell, counsel for the Underwriters,
at 450 Lexington Avenue, New York, New York, 10016, on the Closing Date.

          7. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
because of any termination pursuant to Section 10 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally through the Representatives on demand for all out-of-pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
reasonably incurred by them in connection with the proposed purchase and sale of
the Securities.

          8. Indemnification and Contribution.

          (a) The Company agrees to indemnify and hold harmless each
     Underwriter, the directors, officers, employees and agents of each
     Underwriter and each person who controls any Underwriter within the meaning
     of either the Securities Act or the Exchange Act against any and all
     losses, claims, damages or liabilities, joint or several, to which they or
     any of them may become subject under the Securities Act, the Exchange Act
     or other Federal or state statutory law or regulation, at common law or
     otherwise, insofar as such losses, claims, damages or liabilities (or
     actions in respect thereof) arise out of or are based upon any untrue
     statement or alleged untrue statement of a material fact contained in the
     registration statement for the registration of the Securities as originally
     filed or in any amendment thereof, or in the Basic Prospectus, any
     Preliminary Final Prospectus or the Final Prospectus, or in any amendment
     thereof or supplement thereto, or arise out of or are based upon the
     omission or alleged omission to state therein a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, and agrees to reimburse each such indemnified party, as
     incurred, for any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such loss, claim, damage,
     liability or action; provided, however, that the Company will not be liable
     in any such case to the extent that any such loss, claim, damage or
     liability arises out of or is based upon any such untrue statement or
     alleged untrue statement or omission or alleged omission made therein in
     reliance upon and in conformity with written information furnished to the
     Company by or on behalf of any Underwriter through

                                                                              21


     the Representatives specifically for inclusion therein and provided,
     further, that the foregoing indemnity obligations with respect to the
     Preliminary Final Prospectus shall not inure to the benefit of the
     Underwriters, or any person controlling the Underwriters within the meaning
     of the securities laws if a copy of the Final Prospectus (as then amended
     or supplemented) was not sent or given by or on behalf of the Underwriters
     to the person asserting such losses, claims, damages or liabilities who
     purchased the Securities from the Underwriters, if required by law so to
     have been delivered, at or prior to the written confirmation of the sale of
     the Securities to such person, and if the Final Prospectus (as then amended
     or supplemented) would have cured the defect giving rise to such losses,
     claims, damages or liabilities, unless such failure is the result of
     noncompliance by the Company with Section 5(d) hereof.

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

          (c) Promptly after receipt by an indemnified party under this Section
     8 of notice of the commencement of any action, such indemnified party will,
     if a claim in respect thereof is to be made against the indemnifying party
     under this Section 8, notify the indemnifying party in writing of the
     commencement thereof; but the failure so to notify the indemnifying party
     (i) will not relieve it from liability under paragraph (a) or (b) above
     unless and to the extent it did not otherwise learn of such action and such
     failure results in the forfeiture by the indemnifying party of substantial
     rights and defenses and (ii) will not, in any event, relieve the
     indemnifying party from any obligations to any indemnified party other than
     the indemnification obligation provided in paragraph (a) or (b) above. The
     indemnifying party shall be entitled, in its sole discretion, to assume the
     defense of such claim and to appoint counsel of the indemnifying party's
     choice at the indemnifying party's expense to represent the indemnified
     party in

                                                                              22


     any action for which indemnification is sought (in which case the
     indemnifying party shall not thereafter be responsible for the fees and
     expenses of any separate counsel retained by the indemnified party or
     parties except as set forth below); provided, however, that such counsel
     shall be satisfactory to the indemnified party. Notwithstanding the
     indemnifying party's election to appoint counsel to represent the
     indemnified party in an action, the indemnified party shall have the right
     to employ separate counsel (including local counsel), and the indemnifying
     party shall bear the reasonable fees, costs and expenses of such separate
     counsel if (i) the use of counsel chosen by the indemnifying party to
     represent the indemnified party would present such counsel with a conflict
     of interest, (ii) the actual or potential defendants in, or targets of, any
     such action include both the indemnified party and the indemnifying party
     and the indemnified party shall have reasonably concluded that there may be
     legal defenses available to it and/or other indemnified parties which are
     different from or additional to those available to the indemnifying party,
     (iii) the indemnifying party shall not have employed counsel satisfactory
     to the indemnified party to represent the indemnified party within a
     reasonable time after notice of the institution of such action or (iv) the
     indemnifying party shall authorize the indemnified party to employ separate
     counsel at the expense of the indemnifying party. An indemnifying party
     will not, without the prior written consent of the indemnified parties,
     settle or compromise or consent to the entry of any judgment with respect
     to any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification or contribution may be sought hereunder (whether
     or not the indemnified parties are actual or potential parties to such
     claim or action) unless such settlement, compromise, judgment or consent
     includes an unconditional release of each indemnified party from all
     liability arising out of such claim, action, suit or proceeding.

          (d) In the event that the indemnity provided in paragraph (a), (b) or
     (c) of this Section 8 is unavailable to or insufficient to hold harmless an
     indemnified party for any reason, the Company and the Underwriters
     severally agree to contribute to the aggregate losses, claims, damages and
     liabilities (including legal or other expenses reasonably incurred in
     connection with investigating or defending same) (collectively "Losses") to
     which the Company and one or more of the Underwriters may be subject in
     such proportion as is appropriate to reflect the relative benefits received
     by the Company on the one hand and by the Underwriters on the other from
     the offering of the Securities; provided, however, that in no case shall
     any Underwriter (except as may be provided in any agreement among
     underwriters relating to the offering of the Securities) be responsible for
     any amount in excess of the underwriting discount or commission applicable
     to the Securities purchased by such Underwriter hereunder. If the
     allocation provided by the immediately preceding sentence is unavailable
     for any reason, the Company and the Underwriters severally shall contribute
     in such proportion as is appropriate to reflect not only such relative
     benefits but also the relative fault of the Company on the one hand and of
     the Underwriters on the

                                                                              23


     other in connection with the statements or omissions which resulted in such
     Losses as well as any other relevant equitable considerations. Benefits
     received by the Company shall be deemed to be equal to the total net
     proceeds from the offering (before deducting expenses) received by it, and
     benefits received by the Underwriters shall be deemed to be equal to the
     total underwriting discounts and commissions, in each case as set forth on
     the cover page of the Final Prospectus. Relative fault shall be determined
     by reference to, among other things, whether any untrue or any alleged
     untrue statement of a material fact or the omission or alleged omission to
     state a material fact relates to information provided by the Company on the
     one hand or the Underwriters on the other, the intent of the parties and
     their relative knowledge, access to information and opportunity to correct
     or prevent such untrue statement or omission. The Company and the
     Underwriters agree that it would not be just and equitable if contribution
     were determined by pro rata allocation or any other method of allocation
     which does not take account of the equitable considerations referred to
     above. Notwithstanding the provisions of this paragraph (d), no person
     guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
     of the Securities Act) shall be entitled to contribution from any person
     who was not guilty of such fraudulent misrepresentation. For purposes of
     this Section 8, each person who controls an Underwriter within the meaning
     of either the Securities Act or the Exchange Act and each director,
     officer, employee and agent of an Underwriter shall have the same rights to
     contribution as such Underwriter, and each person who controls the Company
     within the meaning of either the Securities Act or the Exchange Act, each
     officer of the Company who shall have signed the Registration Statement and
     each director of the Company shall have the same rights to contribution as
     the Company, subject in each case to the applicable terms and conditions of
     this paragraph (d).

          9. Default by an Underwriter. If any one or more Underwriters shall
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take and
pay for (in the respective proportions which the principal amount of Securities
set forth opposite their names in Schedule II hereto bears to the aggregate
principal amount of Securities set forth opposite the names of all the remaining
Underwriters) the Securities which the defaulting Underwriter or Underwriters
agreed but failed to purchase; provided, however, that in the event that the
aggregate principal amount of Securities which the defaulting Underwriter or
Underwriters agreed but failed to purchase shall exceed 10% of the aggregate
principal amount of Securities set forth in Schedule II hereto, the remaining
Underwriters shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the Securities, and if such nondefaulting
Underwriters do not purchase all the Securities within 36 hours of such default,
this Agreement will terminate without liability to any nondefaulting Underwriter
or the Company. In the event of a default by any Underwriter as set forth in
this Section 9, the Closing Date shall be postponed for such period, not
exceeding five

                                                                              24


Business Days, as the Representatives shall determine in order that the required
changes in the Registration Statement and the Final Prospectus or in any other
documents or arrangements may be effected. Nothing contained in this Agreement
shall relieve any defaulting Underwriter of its liability, if any, to the
Company and any nondefaulting Underwriter for damages occasioned by its default
hereunder.

          10. Termination. This Agreement shall be subject to termination in the
absolute discretion of the Representatives, by notice given to the Company prior
to delivery of and payment for the Securities, if at any time prior to such time
(i) trading in the Company's Common Stock shall have been suspended by the
Commission or the New York Stock Exchange or trading in securities generally on
the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (ii) a banking moratorium
shall have been declared either by Federal or New York State authorities or
(iii) there shall have occurred any outbreak or escalation of hostilities,
declaration by the United States of a national emergency or war, or other
calamity or crisis the effect of which on financial markets is such as to make
it, in the sole judgment of the Representatives, impractical or inadvisable to
proceed with the offering or delivery of the Securities as contemplated by the
Final Prospectus (exclusive of any supplement thereto).

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

          12. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telefaxed to each of (a) the Citigroup Global Markets Inc. General

Attention: Alan G. Berkshire, Esq.

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

                                                                              25


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

          15. Counterparts. This Agreement may be signed in one or more
