Ladies and Gentlemen:
 
  FMC Corporation, a Delaware corporation (the "Company"), proposes to issue
and sell to the several Underwriters named in Schedule I hereto (the
"Underwriters") $100,000,000 principal amount of its 7 3/4% Senior Debentures
Due 2011 (the "Securities"). The Securities are to be issued pursuant to the
provisions of an Indenture dated as of July 1, 1996 (the "Indenture") between
the Company and Harris Trust and Savings Bank, as Trustee.
 
  The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3, which has become
effective, for the registration under the Securities Act of 1933, as amended
(the "Securities Act"), of certain securities (the "Shelf Securities") to be
issued from time to time by the Company. The Company proposes to file with the
Commission pursuant to Rule 424 under the Securities Act a prospectus
supplement specifically relating to the Securities and the plan of
distribution thereof and has previously advised you of all further information
with respect to the Company to be set forth therein. The registration
statement, including exhibits, as amended at the date of this Agreement, is
hereinafter referred to as the Registration Statement and the related
prospectus covering the Shelf Securities dated November 20, 1995 is
hereinafter referred to as the Basic Prospectus. Any preliminary form of the
prospectus supplement filed with the Commission pursuant to Rule 424 shall be
referred to as a preliminary prospectus. The Basic Prospectus as supplemented
by the prospectus supplement specifically relating to the Securities is
hereinafter called the Final Prospectus. All references to the Registration
Statement, the Basic Prospectus, a preliminary prospectus and the Final
Prospectus include the documents incorporated therein by reference.
 
                                      I.
 
  The Company hereby agrees to sell to the several Underwriters named in
Schedule I hereto, and the Underwriters, upon the basis of the representations
and warranties herein contained, but subject to the conditions hereinafter
stated, agree, severally and not jointly, to purchase from the Company, the
respective principal amounts of Securities set forth in Schedule I hereto
opposite their names at 98.177% of their principal amount plus accrued
interest from July 1, 1996--the purchase price.
 
  The Company hereby agrees that, without your prior written consent, it will
not offer, sell, contract to sell or otherwise dispose of any debt securities
of the Company which are substantially similar to the Securities until the
business day following the Closing Date, other than the Securities to be sold
hereunder.
 
                                      II.
 
  The Company is advised by you that the Underwriters propose to make a public
offering of their respective portions of the Securities as soon after this
Agreement has become effective as in your judgment is advisable.
 
                                       1

 
The Company is further advised by you that the Securities are to be offered to
the public initially at 98.927% of their principal amount plus accrued
interest from July 1, 1996--the public offering price--and to certain dealers
selected by you at a price that represents a concession not in excess of 0.50%
of their principal amount under the public offering price, and that any
Underwriter may allow, and such dealers may reallow, a concession, not in
excess of 0.25% of their principal amount, to any Underwriter or to certain
other dealers.
 
                                     III.
 
  Payment for the Securities shall be made by wire transfer to the Company in
immediately available (same day) funds at the office of Winston & Strawn,
Chicago, Illinois, at 10:00 A.M., New York time, on July 2, 1996, or at such
other time on the same or such other date, not later than July 9, 1996, as
shall be designated in writing by you. The time and date of such payment are
hereinafter referred to as the Closing Date.
 
  Payment for the Securities shall be made against delivery to you in New York
City for the respective accounts of the several Underwriters of the Securities
registered in such names and in such denominations as you shall request in
writing not later than two full business days prior to the date of delivery,
with any transfer taxes payable in connection with the transfer of the
Securities to the Underwriters duly paid.
 
                                      IV.
 
  The several obligations of the Underwriters hereunder are subject to the
following conditions:
 
    (a) (i) No stop order suspending the effectiveness of the Registration
  Statement shall be in effect, and no proceedings for such purpose shall be
  pending before or threatened by the Commission;
 
    (ii) subsequent to the execution and delivery of this Agreement and prior
  to the Closing Date, there shall not have occurred any downgrading, nor
  shall any notice have been given of any intended or potential downgrading,
  in the rating accorded any of the Company's securities by any "nationally
  recognized statistical rating organization," as such term is defined for
  purposes of Rule 436(g)(2) under the Securities Act;
 
    (iii) subsequent to the execution and delivery of this Agreement and
  prior to the Closing Date, there shall not have occurred any change, or any
  development involving a prospective change, in the condition, financial or
  otherwise, 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, that, in your judgment, is material and adverse and that makes
  it, in your judgment, impracticable to market the Securities on the terms
  and in the manner contemplated in the Final Prospectus; and
 
    (iv) you shall have received on the Closing Date a certificate, dated the
  Closing Date and signed by an executive officer of the Company, to the
  effect set forth in clauses (i) and (ii) above, to the effect that the
  representations and warranties of the Company contained herein are true and
  correct as of the Closing Date and to the effect that there has not
  occurred any material adverse change, or any development involving a
  prospective material adverse change, in the condition, financial or
  otherwise, or in the earnings, business or operations, of the Company and
  its subsidiaries, taken as a whole, from that set forth in the Final
  Prospectus.
 
  The officer signing and delivering such certificate may rely upon the best
of his knowledge as to proceedings threatened.
 
    (b) You shall have received on the Closing Date an opinion of Winston &
  Strawn, counsel for the Company, dated the Closing Date, to the effect
  that:
 
      (i) the Indenture has been duly authorized, executed and delivered by

    as to enforcement of remedies, to bankruptcy, insolvency, fraudulent
    conveyance, moratorium, reorganization and other laws of general
    applicability relating to or affecting creditors' rights and to
 
                                       2

    considered in a proceeding in equity or at law and has been duly
    qualified under the Trust Indenture Act of 1939, as amended;
 
      (ii) the Securities have been duly authorized and, when executed and
    authenticated in accordance with the provisions of the Indenture and
    delivered to and paid for by you in accordance with the terms of this
    Agreement, will be valid and binding obligations of the Company
    enforceable against the Company in accordance with their terms subject,
    as to enforcement of remedies, to bankruptcy, insolvency, fraudulent
    conveyance, moratorium, reorganization and other laws of general

    the benefits of the Indenture;
 
      (iii) this Agreement has been duly authorized, executed and delivered
    by the Company;
 
      (iv) the execution, delivery and performance of this Agreement, the

    or provisions of, or constitute a default under, the certificate of
    incorporation or by-laws of the Company, or the 5-Year Credit Agreement
    dated as of December 16, 1994 among the Company, the lenders listed
    therein and Morgan Guaranty Trust Company of New York, as Agent, or the

      (v) no authorization, consent, approval or order of any court or
    governmental agency or body in the United States or any state or
    political subdivision thereof is required for the issuance or sale of
    or performance of the Company's obligations with respect to the

    laws of the various states in connection with the purchase and
    distribution of the Securities by the Underwriters;
 
      (vi) the statements in the Final Prospectus under "Description of

    which such counsel need not express any opinion) comply as to form in
    all material respects with the Securities Act and the rules and
    regulations of the Commission thereunder.

  that part of the Registration Statement that constitutes the Form T-1
  hereinafter referred to as to which such counsel need not express any
  belief) the Registration Statement at the time the Registration Statement
  became effective contained any 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 that the Final Prospectus,
  as of the Closing Date, contains any untrue statement of a material fact or
  omits to state a material fact necessary in order to make the statements
  therein, in light of the circumstances under which they were made, not
  misleading.
 
    (c) You shall have received on the Closing Date an opinion of the General
  Counsel or Assistant General Counsel for the Company, dated the Closing
  Date, to the effect that:
 
 
                                       3

 
      (i) the Company is validly existing as a corporation in good standing
    under the laws of Delaware and is duly qualified to transact business
    and is in good standing in each jurisdiction in which the conduct of
    its business or the 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 on the
    Company and its subsidiaries, taken as a whole, and has all corporate
    power and authority under its certificate of incorporation, bylaws and
    the laws of the State of Delaware to own, lease and operate its
    properties and conduct its business as described in the Final
    Prospectus;
 
      (ii) each Significant Subsidiary (as defined in Regulation S-X
    promulgated by the Commission) of the Company is validly existing as a
    corporation in good standing under the laws of the jurisdiction of its
    incorporation and is duly qualified to transact business and is in good
    standing in each jurisdiction in which the conduct of its business or
    the 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 on the Company and
    its subsidiaries, taken as whole;
 
      (iii) neither the Company nor any subsidiary is in violation of its
    certificate of incorporation or by-laws or, to the best of such
    counsel's knowledge after due inquiry, in default in the performance of
    any obligation, agreement or condition contained in any bond,
    debenture, note or any other evidence of indebtedness or in any
    indenture, lease, loan agreement or other instrument governing any
    indebtedness to which the Company or any subsidiary is a party or by
    which the Company or any subsidiary or their property or claims is
    bound, except to the extent that such violation or default would not
    have a material adverse effect on the Company and its subsidiaries,
    taken as a whole;
 
      (iv) such counsel is not aware after due inquiry of the Company's
    failure to possess or to be in compliance with any franchises, grants,
    authorizations, licenses, permits, easements, consents, certificates or
    orders required for the conduct of the business of the Company or any
    subsidiary, except to the extent that the failure to so possess or
    comply would not have a material adverse effect on the Company and its
    subsidiaries, taken as a whole;
 
      (v) except as disclosed in the Final Prospectus, the equity
    securities of each direct or indirect subsidiary of the Company listed
    on Exhibit 21 to the Company's most recent Annual Report on Form 10-K
    which is a Significant Subsidiary (as defined above) are owned by the
    Company or a subsidiary of the Company to the extent described therein
    free and clear of all liens and encumbrances and any other adverse
    claims (other than directors' qualifying shares and shares of common
    stock of FMC Gold Company which are exchangeable for the Exchangeable
    Debentures);
 
      (vi) the execution, delivery and performance of this Agreement, the
    Securities and the Indenture by the Company and the issuance and sale
    of the Securities by the Company as provided in this Agreement and the
    Indenture, will not result in a breach or violation of any of the terms
    or provisions of, or constitute a default under, the certificate of
    incorporation of the Company or any Significant Subsidiary, or any
    provision of applicable law or administrative regulation known to such
    counsel or any agreement or other instrument known to such counsel
    binding upon the Company or any subsidiary and which is material to the
    Company and its subsidiaries taken as a whole or any decree of any
    court known to such counsel applicable to the Company or any
    subsidiaries or any of their properties;
 
      (vii) there is no action, suit or proceeding pending or threatened
    against or affecting the Company or any of its properties before or by
    any court, governmental official, commission, board of other
    administrative agency or arbitrator that has a reasonable probability
    (taking into account the exhaustion of all appeals) of having a
    material adverse effect on the business, operations, properties,
    consolidated financial condition, consolidated results of operations or
    business prospects of the Company, except as disclosed in the Final
    Prospectus, or that in any manner questions the validity of this
    Agreement, the Indenture or the Securities;
 
      (viii) such counsel does not know of any legal or governmental
    proceeding pending or threatened to which the Company or any of its
    subsidiaries is a party or to which any of the properties of the
    Company or any of its subsidiaries is subject that is required to be
    described in the Registration
 
                                       4

 
    Statement or the Final Prospectus and is not so described or of any
    contract or other document which is required to be described in the
    Registration Statement or the Final Prospectus or to be filed as an
    exhibit to the Registration Statement that is not described or filed as
    required; and
 
      (ix) each document incorporated by reference in the Registration
    Statement and the Final Prospectus (except for financial statements and
    schedules and other financial data as to which such counsel need not
    express any opinion) complied as to form when filed with the Commission
    in all material respects with the Securities Exchange Act of 1934, as
    amended (the "Exchange Act"), and the rules and regulations of the
    Commission thereunder.
 
    Such counsel shall also have furnished to you a written statement, in
  form and substance satisfactory to you, to the effect that nothing has come
  to such counsel's attention that causes such counsel to believe that
  (except for financial statements and schedules and other financial data and
  except for that part of the Registration Statement that constitutes the
  Form T-1 hereinafter referred to as to which such counsel need not express
  any belief) the Registration Statement at the time it became effective
  contained any 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 that the Final Prospectus, as of the
  Closing Date, contains any untrue statement of a material fact or omits to
  state a material fact necessary in order to make the statements therein, in
  light of the circumstances under which they were made, not misleading.
 
    (d) You shall have received on the Closing Date an opinion of Mayer,
  Brown & Platt, counsel for the Underwriters, dated the Closing Date,
  covering the matters referred to in subparagraphs (i), (ii), (iii), (vi)
  (but only as to the statements in the Final Prospectus under "Description
  of Senior Debentures," "General Description of the Offered Securities" and
  "Description of the Debt Securities") and (vii) (but as to the Registration
  Statement only as of the date of this Agreement) of paragraph (b) above.
  Such counsel shall also have furnished to you a written statement to the
  same effect as the last sentence of paragraph (b) above.
 
    With respect to the last sentence of paragraph (c) above, such counsel
  may state that such counsel's belief is based upon his participation in the
  preparation of the Registration Statement and Final Prospectus and any
  amendments or supplements thereto and documents incorporated therein by
  reference and review and discussion of the contents thereof, but is without
  independent check or verification except as specified. With respect to the
  last sentence of paragraph (b) above, Winston & Strawn and Mayer, Brown &
  Platt may state that their belief is based upon their participation in the
  preparation of the Registration Statement and Final Prospectus and any
  amendments or supplements thereto (but not including documents incorporated
  therein by reference) and review and discussion of the contents thereof
  (including documents incorporated therein by reference), but is without
  independent check or verification except as specified.
 
    (e) You shall have received on the Closing Date a letter dated the
  Closing Date, in form and substance satisfactory to you, from KPMG Peat
  Marwick LLP and Ernst & Young LLP, independent public accountants,
  containing statements and information of the type ordinarily included in
  accountants' "comfort letters" to underwriters with respect to the
  financial statements and certain financial information contained in or
  incorporated by reference in the Registration Statement and the Final
  Prospectus.
 
                                      V.
 
  In further consideration of the agreements of the Underwriters herein
contained, the Company covenants as follows:
 
    (a) To furnish you, without charge, two copies of the Registration
  Statement as filed with the Commission (including exhibits thereto and
  documents incorporated therein by reference) and, during the period
  mentioned in paragraph (c) below, as many copies of the Final Prospectus,
  any documents incorporated therein by reference, and any supplements and
  amendments thereto as you may reasonably request. The terms "supplement"
  and "amendment" or "amend" as used in this Agreement shall include all
  documents subsequently filed by the Company with the Commission pursuant to
  the Exchange Act that are deemed to be incorporated by reference in the
  Final Prospectus.
 
 
                                       5

 
    (b) Before amending or supplementing the Registration Statement or the
  Final Prospectus with respect to the Securities, to furnish you a copy of
  each such proposed amendment or supplement, and to file no such proposed
  amendment or supplement (other than quarterly and annual reports on Forms
  10-Q and 10-K covering periods commencing after December 31, 1995 or
  current reports on Form 8-K covering events occurring after December 31,
  1995) to which you reasonably object.
 
    (c) If, during such period after the first date of the public offering of
  the Securities and prior to the completion of the distribution of the
  Securities, as determined by you, any event shall occur as a result of
  which it is necessary to amend or supplement the Final Prospectus in order
  to make the statements therein, in the light of the circumstances when the
  Final Prospectus is delivered to a purchaser, not misleading, or if it is
  necessary to amend or supplement the Final Prospectus to comply with law,
  forthwith to prepare and furnish, at its own expense, to the Underwriters
  and to the dealers (whose names and addresses you will furnish to the
  Company) to which Securities may have been sold by you on behalf of the
  Underwriters and to any other dealers upon request, either amendments or
  supplements to the Final Prospectus so that the statements in the Final
  Prospectus as so amended or supplemented will not, in the light of the
  circumstances when the Final Prospectus is delivered to a purchaser, be
  misleading or so that the Final Prospectus will comply with law.
 
    (d) To endeavor with the assistance of your counsel to qualify the
  Securities for offer and sale under the securities or Blue Sky laws of such
  jurisdictions as you shall reasonably request and to pay all reasonable
  expenses (including fees and disbursements of counsel) in connection with
  such qualification and in connection with the determination of the
  eligibility of the Securities for investment under the laws of such
  jurisdictions as you may designate, as well as all filing fees payable in
  connection with the review (if any) of the offering of the Securities by
  the National Association of Securities Dealers, Inc.; provided, however,
  that in connection therewith the Company shall not be obligated to qualify
  as a foreign corporation in any jurisdiction in which it is not so
  qualified, to file a general consent to service of process in any
  jurisdiction or to subject itself to taxation in respect of doing business
  in any jurisdiction in which it is not otherwise subject.
 
    (e) To make generally available to the Company's security holders as soon
  as practicable an earnings statement covering the twelve-month period
  ending June 30, 1997, that satisfies the provisions of Section 11(a) of the
  Securities Act and the rules and regulations of the Commission thereunder.
 
                                      VI.
 
  The Company represents and warrants to each Underwriter that (i) each
document filed or to be filed pursuant to the Exchange Act, and incorporated
by reference in the Final Prospectus, complied or will comply when so filed in
all material respects with the Exchange Act, and the rules and regulations
thereunder, (ii) the Registration Statement complied when filed in all
material respects with the Securities Act and the rules and regulations of the
Commission thereunder, (iii) each preliminary prospectus filed pursuant to
Rule 424 under the Securities Act complied when so filed in all material
respects with the Securities Act and the rules and regulations of the
Commission thereunder, (iv) the Registration Statement and Final Prospectus
(as amended or supplemented if the Company shall have furnished any amendments
or supplements thereto) will comply in all material respects with the
Securities Act and the rules and regulations of the Commission thereunder and
will not contain 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; except that the foregoing representations
and warranties shall not apply to (a) that part of the Registration Statement
that constitutes the Statement of Eligibility (Form T-1) under the Trust
Indenture Act of 1939 of Harris Trust and Savings Bank, Trustee under the
Indenture, and (b) statements or omissions in the Registration Statement,
Basic Prospectus or the Final Prospectus based upon information furnished to
the Company in writing by any Underwriter through you expressly for use
therein and (v) the Company has complied with all provisions of Section
517.075, Florida Statutes (Chapter 92-198, Laws of Florida).
 
                                       6

 
  The Company agrees to indemnify and hold harmless each Underwriter and each
person, if any, who controls any Underwriter within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and
against any and all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred by any
Underwriter or any such controlling person in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement or the Final Prospectus (as amended or supplemented if the Company
shall have furnished any amendments or supplements thereto) or any preliminary
prospectus, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information furnished to the
Company in writing by any Underwriter expressly for use therein; provided,
however, that the foregoing indemnity agreement with respect to any
preliminary prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting any such losses, claims, damages or liabilities
purchased Securities, or any person controlling such Underwriter, if a copy of
the Final Prospectus (as then amended or supplemented if the Company shall
have furnished any amendments or supplements thereto) was not sent or given by
or on behalf of such Underwriter to such person, if required by law so to have
been delivered, at or prior to the written confirmation of the sale of the
Securities to such person, and if the Final Prospectus (as so amended or
supplemented) would have cured the defect giving rise to such loss, claim,
damage or liability.
 
  Each Underwriter agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act
to the same extent as the foregoing indemnity from the Company to each
Underwriter, but only with reference to information relating to such
Underwriter furnished to the Company in writing by such Underwriter through
you expressly for use in the Registration Statement, the Final Prospectus, any
amendment or supplement thereto, or any preliminary prospectus.
 
  In case any proceeding (including any governmental investigation) shall be
instituted involving any person in respect of which indemnity may be sought
pursuant to either of the two preceding paragraphs, such person (hereinafter
called the indemnified party) shall promptly notify the person against whom
such indemnity may be sought (hereinafter called the indemnifying party) in
writing and the indemnifying party, upon request of the indemnified party,
shall retain counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others the indemnifying party may
designate in such proceeding and shall pay the reasonable fees and
disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the reasonable fees and expenses of such counsel shall be at the
expense of such indemnified party unless (i) the indemnifying party and the
indemnified party shall have mutually agreed to the retention of such counsel
or (ii) the named parties to any such proceeding (including any impleaded
parties) include both the indemnifying party and the indemnified party and
representation of both parties by the same counsel would be inappropriate due
to actual or potential differing interests between them. It is understood that
the indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all such
indemnified parties, and that all such fees and expenses shall be reimbursed
as they are incurred. Such firm shall be designated in writing by Morgan
Stanley & Co. Incorporated in the case of parties indemnified pursuant to the
second paragraph of this Article VI and by the Company in the case of parties
indemnified pursuant to the third paragraph of this Article VI. The
indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party to the extent set forth above from and against
any loss or liability by reason of such settlement or judgment. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in
respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement
 
                                       7

 
includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.
 
  If the indemnification provided for in the second or third paragraph of this
Article VI is, as a matter of applicable law, unavailable to an indemnified
party in respect of any losses, claims, damages or liabilities for which
indemnification is provided therein, then each indemnifying party under such
paragraph, in lieu of indemnifying such indemnified party thereunder, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Underwriters 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 and
of the Underwriters in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the
Company and the Underwriters shall be deemed to be in the same respective
proportions as the net proceeds from the offering (before deducting expenses)
received by the Company and the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover of the Final Prospectus, bear to the aggregate public offering price of
the Securities. The relative fault of the Company and the Underwriters shall
be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the
Company or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.
 
  The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Article VI were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of
the losses, claims, damages and liabilities referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Article VI, 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 that such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Underwriters'
obligations to contribute pursuant to this Article VI are several in
proportion to the respective principal amount of Securities purchased by each
Underwriter and not joint.
 
  The indemnity and contribution agreements contained in this Article VI and
the representations and warranties of the Company contained in this Agreement
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
any Underwriter or any person controlling any Underwriter or by or on behalf
of the Company, its officers or directors or any other person controlling the
Company and (iii) acceptance of and payment for any of the Securities.
 
                                     VII.
 
  This Agreement shall be subject to termination, by notice given by you to
the Company, if (a) after the execution and delivery of this Agreement and
prior to the Closing Date (i) trading generally shall have been suspended or
materially limited on or by, as the case may be, any of the New York Stock
Exchange, the
 
                                       8

 
American Stock Exchange or the National Association of Securities Dealers,
Inc., (ii) trading of the Securities or the Common Stock of the Company shall
have been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have
been declared by either Federal or New York State authorities, or (iv) there
shall have occurred any outbreak or escalation of major hostilities or any
significant change in financial markets or any calamity or crises that, in
your judgment, is material and adverse and (b) in the case of any of the
events specified in clauses (a)(i) through (iv), such event singly or together
with any other such event makes it, in your judgment, impracticable to market
the Securities substantially on the terms and in the manner contemplated in
the Final Prospectus. Any such termination shall be without liability on the
part of any Underwriter or the Company.
 
                                     VIII.
 
  This Agreement shall become effective upon execution and delivery hereof by
the parties hereto.
 
  If, on the Closing Date, any one or more of the Underwriters shall fail or
refuse to purchase Securities that it or they have agreed to purchase
hereunder on such date, and the aggregate principal amount of Securities which
such defaulting Underwriter or Underwriters agreed but failed or refused to
purchase is not more than one-tenth of the aggregate principal amount of the
Securities to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the principal amount of Securities
set forth opposite their respective names in Schedule I bears to the principal
amount of Securities set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as you may specify, to purchase the
Securities which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date; provided that in no event shall the
principal amount of Securities that any Underwriter has agreed to purchase
pursuant to Article I be increased pursuant to this Article VIII by an amount
in excess of one-ninth of such principal amount of Securities without the
written consent of such Underwriter. If, on the Closing Date, any Underwriter
or Underwriters shall fail or refuse to purchase Securities and the aggregate
principal amount of Securities with respect to which such default occurs is
more than one-tenth of the aggregate principal amount of Securities to be
purchased on such date, and arrangements satisfactory to you and the Company
for the purchase of such Securities are not made within 36 hours after such
default, this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter or the Company. In any such case either you or the
Company shall have the right to postpone the Closing Date, but in no event for
longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Final Prospectus or in any other documents
or arrangements may be effected. Any action taken under this paragraph shall
not relieve any defaulting Underwriter from liability in respect of any
default of such Underwriter under this Agreement.
 
  If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with
the terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for
all out-of-pocket expenses (including the reasonable fees and disbursements of
their counsel) reasonably incurred by such Underwriters in connection with
this Agreement or the offering contemplated hereunder.
 
  The Underwriters agree to advise the Company promptly of the completion of
the distribution of the Securities.
 
  This Agreement may be signed in two or more counterparts, each of which
shall be an original, with the same effect as if the signatures thereto and
hereto were upon the same instrument.
 
                                       9

 
  This Agreement shall be governed by and construed in accordance with the
internal laws of the State of New York.
