Ladies and Gentlemen:

      TARGETS Trust [XXV] (the "Trust"), a statutory trust organized under the
Statutory Trust Act (the "Delaware Act") of the State of Delaware (Chapter 38,
Title 12, of the Delaware Business Code, 12 Del. C. Section 3801 et seq.),
proposes, upon the terms and conditions set forth herein, to issue and sell to
[-] of its Targeted Growth Enhanced Terms Securities (TARGETS(R)) (the

pursuant to the terms of a declaration of trust, dated as of ____________, 20__,
and to be amended and restated on ____________, 20__ (the "Declaration"), among
Citigroup Funding Inc., a Delaware corporation, as sponsor (the "Company"),
Citigroup Inc., a Delaware corporation, as guarantor (the "Guarantor" and,
together with the Company and the Trust, the "Offerors"), the trustees named
therein (the "TARGETS Trustees") and the holders from time to time of undivided
beneficial interests in the assets of the Trust. The Declaration is qualified as
an indenture under the Trust Indenture Act.

      Any reference herein to the Registration Statement, the Basic Prospectus,
any Preliminary Prospectus or the Prospectus shall be deemed to refer to and
include the documents incorporated by reference therein pursuant to Item 12 of
Form S-3 which were filed under the Exchange Act on or before the Effective Date
of the Registration Statement or the issue date of the Basic Prospectus, any
Preliminary Prospectus or the Prospectus, as the case may be; and any reference
herein to the terms "amend," "amendment" or "supplement" with respect to the
Registration Statement, the Basic



Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to
refer to and include the filing of any document under the Exchange Act after the
Effective Date of the Registration Statement or the issue date of the Basic
Prospectus, any Preliminary Prospectus or the Prospectus, as the case may be,
deemed to be incorporated therein by reference. Certain terms used herein are
defined in Section 16 hereof.

      The TARGETS represent undivided beneficial ownership interests in the
assets of the Trust. The assets of the Trust will consist solely of (i) a
forward contract with respect to the Common Stock of ____________, purchased by
the Trust from the Company (the "Forward Contract") and (ii) a portfolio of

Guarantor and JPMorgan Chase Bank, N.A., a national banking association, as
trustee (the "Guarantee Trustee"), are to enter into the TARGETS Guarantee
Agreement dated as of ____________, 20__ (the "Guarantee") with respect to the
TARGETS. The Guarantee, when taken together with the Forward Contract and the
Company's obligation to pay all fees and expenses of the Trust, constitutes a
full and unconditional guarantee by the Company and the Guarantor of all
payments to be made to the holders of the TARGETS. The TARGETS, the Guarantee
and the Forward Contract are hereinafter collectively referred to as the
"Securities."

            1. Representations and Warranties. The Offerors represent and
warrant to, and agree with, you, as Underwriter, as set forth below in this
Section 1.

            (a) The Offerors meet the requirements for use of Form S-3 under the
Act and have prepared and filed with the Commission a registration statement on
Form S-3 (File No. 333- ), including a related basic prospectus, for
registration under the Act of the offering and sale of the Securities. The
Offerors may have filed one or more amendments thereto, including a Preliminary
Prospectus, each of which has previously been furnished to you. The Offerors
will next file with the Commission a final prospectus relating to the Securities
in accordance with Rules 415 and 424(b). As filed, such Prospectus shall contain
all required information, and, except to the extent you shall agree in writing
to a modification, shall be in all substantive respects in the form furnished to
you prior to the Execution Time or, to the extent not completed at the Execution
Time, shall contain only such specific additional information and other changes
(beyond that contained in the Basic Prospectus and any Preliminary Prospectus)
as the Company, the Guarantor or the Trust has advised you, prior to the
Execution Time, will be included or made therein. The Registration Statement, at
the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x).

            (b) On the Effective Date, the Registration Statement did or will,
and when the Prospectus is first filed (if required) in accordance with Rule
424(b) and on the Closing Date (as defined herein), the Prospectus (and any
supplement thereto) will, comply in all material respects with the applicable
requirements of the Act, the Exchange Act and the Trust Indenture Act and the
respective rules thereunder; on the Effective Date and at the Execution Time,
the Registration Statement did not or will not contain any



untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary in order to make the statements therein not
misleading; on the Effective Date and on the Closing Date, the Declaration did
or will comply in all material respects with the applicable requirements of the
Trust Indenture Act and the rules thereunder; and, on the Effective Date, the
Prospectus, if not filed pursuant to Rule 424(b), will not, and on the date of
any filing pursuant to Rule 424(b) and on the Closing Date, the Prospectus
(together with any supplement thereto) will not, include any untrue statement of
a material fact or omit 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; provided, however, that the Offerors make no
representations or warranties as to (i) that part of the Registration Statement
which shall constitute the Statement of Eligibility and Qualification (Form T-1)
under the Trust Indenture Act of each of the Institutional Trustee, the
Guarantee Trustee and the Delaware Trustee or (ii) the information contained in
or omitted from the Registration Statement or the Prospectus (or any supplement
thereto) in reliance upon and in conformity with information furnished in
writing to the Offerors by or on behalf of you, as Underwriter, specifically for
inclusion in the Registration Statement or the Prospectus (or any supplement
thereto).

            Any certificate signed by any officer of the Company or the
Guarantor or by any trustee of the Trust and delivered to you, as Underwriter,
or counsel for the Underwriters in connection with the offering of the TARGETS
shall be deemed a representation and warranty by the Company, the Guarantor or
the Trust, as the case may be, as to matters covered thereby, to you, as
Underwriter.

            2. Purchase and Sale. (a) Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, the Trust
agrees to sell to you, as Underwriter, and you, as Underwriter, agree to
purchase from the Trust, at a purchase price of $ per TARGETS, plus accrued
distributions, if any, on the TARGETS from , 20__, [-] TARGETS.

      (b) The Company agrees that, in view of the fact that the proceeds of the
sale of the TARGETS will be invested in the Forward Contract, it shall pay to
you, as Underwriter, as compensation ("Underwriter Compensation") for your
arranging the investment of the proceeds therein, on the Closing Date (as
hereinafter defined), $ per TARGETS.

            3. Delivery and Payment. Delivery of and payment for the TARGETS
shall be made at 10:00 AM, New York City time, on ____________, 20__, or at such
time on such later date not more than three Business Days after the foregoing
date as you shall designate (such date and time of delivery and payment for the
TARGETS being herein called the "Closing Date"). Delivery of the TARGETS shall
be made to you against payment by you of the purchase price thereof to or upon
the order of the Company by wire transfer payable in same-day funds to an
account specified by the



Company. Delivery of the TARGETS shall be made through the facilities of The
Depository Trust Company unless you shall otherwise instruct.

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

            5. Agreements of the Offerors. The Offerors jointly and severally
agree with you, as Underwriter, as follows:

            (a) The Company and the Guarantor will use their best efforts to
      cause the Registration Statement, if not effective at the Execution Time,
      and any amendment thereof, to become effective. Prior to the termination
      of the offering of the Securities, the Offerors will not file any
      amendment of the Registration Statement or supplement (including the
      Prospectus or any Preliminary Prospectus) to the Basic Prospectus or any
      Rule 462(b) Registration Statement unless the Offerors have furnished you
      a copy for your review prior to filing and will not file any such proposed
      amendment or supplement to which you reasonably object. Subject to the
      foregoing sentence, if filing of the Prospectus is otherwise required
      under Rule 424(b), the Offerors will cause the Prospectus, properly
      completed, and any supplement thereto to be filed in a form approved by
      you with the Commission pursuant to the applicable paragraph of Rule
      424(b) within the time period prescribed and will provide evidence
      satisfactory to you of such timely filing. The Offerors will promptly
      advise you (1) when the Registration Statement, if not effective at the
      Execution Time, shall have become effective, (2) when the Prospectus, and
      any supplement thereto, shall have been filed (if required) with the
      Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration
      Statement shall have been filed with the Commission, (3) when, prior to
      termination of the offering of the TARGETS, any amendment to the
      Registration Statement shall have been filed or become effective, (4) of
      any request by the Commission or its staff for any amendment of the
      Registration Statement, or any Rule 462(b) Registration Statement, or for
      any supplement to the Prospectus or for any additional information, (5) of
      the issuance by the Commission of any stop order suspending the
      effectiveness of the Registration Statement or the institution or
      threatening of any proceeding for that purpose and (6) of the receipt by
      the Company, the Guarantor or the Trust of any notification with respect
      to the suspension of the qualification of the TARGETS for sale in any
      jurisdiction or the institution or threatening of any proceeding for such
      purpose. The Company and the Guarantor will use their 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 TARGETS is
      required to be delivered under the Act, any event occurs as a result of
      which the 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 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 Prospectus to comply with the Act or the
      Exchange Act or the respective rules thereunder, the Offerors promptly
      will (1) notify you 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
      Prospectus to you in such quantities as you may reasonably request.

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

            (d) The Offerors will furnish to you and counsel for the
      Underwriters, without charge, signed copies of the Registration Statement
      (including exhibits thereto) 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 Act, as many copies of each
      Preliminary Prospectus and the Prospectus and any supplement thereto as
      you may reasonably request. The Company will pay the expenses of printing
      or other production of all documents relating to the offering.

            (e) The Company and the Guarantor will arrange, if necessary, for
      the qualification of the TARGETS for sale under the laws of such
      jurisdictions as you may designate, will maintain such qualifications in
      effect so long as required for the distribution of the TARGETS 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 either the Company, the Guarantor or the Trust 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 service of
      process in suits, other than those arising out of the offering or sale of
      the TARGETS, in any jurisdiction where it is not now so subject.

            (f) None of the Company, the Guarantor or the Trust will, without
      your prior written consent, 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, the Guarantor or the Trust or any
      of their respective affiliates or any person in privity with any of them
      or any of their respective affiliates) 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 TARGETS or any
      other securities, including any backup undertakings for such securities,
      of the Company or the Trust, in each case that are substantially similar
      to the TARGETS or any securities convertible into or exchangeable for the
      TARGETS or such substantially similar securities of either the Trust or
      the Company, or publicly announce an intention to effect any such
      transaction, during the period beginning the date of the Underwriting
      Agreement and ending the Closing Date.

            (g) Each of the Company, the Guarantor and the Trust will comply
      with all applicable securities and other laws, rules and regulations,
      including, without limitation, the Sarbanes Oxley Act, and use its best
      efforts to cause its directors and officers (or, in the case of the Trust,
      trustees), in their capacities as such, to comply with such laws, rules
      and regulations, including, without limitation, the provisions of the
      Sarbanes Oxley Act.

            (h) The Offerors 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 security of the Company or the Trust
      to facilitate the sale or resale of the TARGETS.

            (i) The Company and the Guarantor, whether or not the transactions
      contemplated hereunder are consummated or this Agreement is terminated,
      will pay all expenses incident to the performance of the Offerors'
      obligations hereunder, including, without limiting the generality of the
      foregoing, all costs, taxes and expenses incident to the issue and
      delivery of the Securities, all fees and expenses of the Offerors' counsel
      and accountants, and all costs and expenses incident to the preparing,
      printing, filing and distributing of all documents relating to the
      offering, and will reimburse you, as Underwriter, for any expenses
      (including fees and disbursements of counsel) incurred by you in
      connection with the matters referred to in Section 5(e) hereof and the
      preparation of memoranda relating thereto, for any filing fee of the
      National Association of Securities Dealers, Inc. relating to the TARGETS,
      and for any fees charged by investment rating agencies for rating the
      TARGETS.

            6. Conditions to the Underwriter's Obligations. The obligations of
you, as Underwriter, to purchase the TARGETS shall be subject to the accuracy of
the representations and warranties on the part of the Offerors contained herein
as of the Execution Time and the Closing Date (as if made on the Closing Date),
to the accuracy of the statements of the Offerors made in any certificates
pursuant to the provisions hereof, to the performance by the Offerors of their
obligations hereunder, and to the following additional conditions:

      Registration Statement will become effective not later than (i) 6:00 PM
      New York City time on the date of determination of the public offering
      price, if such determination occurred at or prior to 3:00 PM New York City
      time on such date or (ii) 9:30 AM on the Business Day following the day on
      which the public offering price was determined, if such determination
      occurred after 3:00 PM New York City time on such date; if filing of the
      Prospectus, or any supplement thereto, is required pursuant to Rule
      424(b), the Prospectus, and any such supplement, 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

                  (1) the representations and warranties of the Company and the
                  Guarantor or the Trust, as the case may be, 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
                  and the Guarantor and the Trust, as the case may be, have or
                  has complied with all the agreements and satisfied all the

                  Registration Statement has been issued and no proceedings for
                  that purpose have been instituted or, to the knowledge of the
                  Company and the Guarantor or the Trust, as the case may be,
                  threatened; and

                  (3) since the date of the most recent financial statements
                  included or incorporated by reference in the Prospectus
                  (exclusive of any supplement thereto), there has been no
                  material adverse effect on the condition (financial or
                  otherwise), prospects, earnings, business or properties of the
                  Guarantor 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
                  Prospectus (exclusive of any supplement thereto).

            (g) The Guarantor shall have requested and caused KPMG LLP to have
      furnished to you, at the Closing Date, a customary "comfort letter" (which
      may refer to letters previously delivered to you), dated as of the Closing
      Date, that is satisfactory in content and form to you.

            (h) 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 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 (e) 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 Guarantor 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 Prospectus (exclusive of any supplement thereto) the effect of
      which, in any case referred to in clause (i) or (ii) above, is, in your
      sole judgment, 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 Prospectus (exclusive of any supplement thereto).

            (i) Subsequent to the Execution Time, there shall not have been any
      decrease in the rating of the TARGETS or any of the Company's or the
      Guarantor's debt securities by any "nationally recognized statistical
      rating organization" (as defined for purposes of Rule 436(g) under the
      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.

            (j) Prior to the Closing Date, the Offerors shall have furnished to
      you such further information, certificates and documents as you may
      reasonably request.

            (k) The TARGETS shall have been registered under the Exchange Act
      and shall have been listed and admitted and authorized for trading on the
      American Stock Exchange, upon notice of issuance, and satisfactory
      evidence of such actions shall have been provided to you.

      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
certificates mentioned above or elsewhere in this Agreement shall not be
reasonably satisfactory in form and substance to you and counsel for the
Underwriters, this Agreement and all your obligations hereunder may be canceled
at, or at any time prior to, the Closing Date by you. Notice of such cancelation
shall be given to the Offerors 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 Cleary Gottlieb Steen & Hamilton LLP, counsel for the
Underwriters, at One Liberty Plaza, New York, New York 10006, on the Closing
Date.

            7. Reimbursement of Underwriter's Expenses. If the sale of the
TARGETS 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, the Guarantor or the
Trust to perform any agreement herein or comply with any provision hereof other
than by reason of a default by you, as Underwriter, the Company and the
Guarantor will reimburse you severally on demand for



all out-of-pocket expenses (including reasonable fees and disbursements of
counsel) that shall have been incurred by you in connection with the proposed
purchase and sale of the TARGETS.

            8. Indemnification and Contribution.

            (a) Each of the Company, the Guarantor and the Trust agrees to
      indemnify and hold harmless you, as Underwriter, your directors, officers,
      employees and agents and each person who controls you within the meaning
      of either the 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 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 Prospectus or the
      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 none of
      the Company, the Guarantor or the Trust will 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 any of them by or on
      behalf of you specifically for inclusion therein. This indemnity agreement
      will be in addition to any liability which either the Company, the
      Guarantor or the Trust may otherwise have.

            (b) You, as Underwriter, agree to indemnify and hold harmless the
      Company, the Guarantor and the Trust, each of their respective directors,
      each of their respective officers or, in the case of the Trust, trustees,
      who signs the Registration Statement, and each person who controls the
      Company, the Guarantor or the Trust within the meaning of either the Act
      or the Exchange Act, to the same extent as the foregoing indemnity from
      the Company, the Guarantor and the Trust to you, as Underwriter, but only
      with reference to written information relating to you furnished to the
      Company, the Guarantor or the Trust by or on behalf of you specifically
      for inclusion in the documents referred to in the foregoing indemnity.
      This indemnity agreement will be in addition to any liability that you may
      otherwise have. The Offerors acknowledge that (i) the statements set forth
      in the last paragraph of the cover page regarding delivery of



      the TARGETS and, under the heading "Underwriting", (ii) the list of
      Underwriters and their respective participation in the sale of the
      TARGETS, (iii) the sentences related to concessions and reallowances and
      (iv) the paragraph related to stabilization, syndicate covering
      transactions and penalty bids in any Preliminary Prospectus and the
      Prospectus constitute the only information furnished in writing by or on
      behalf of you for inclusion in any Preliminary Prospectus or the
      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 to appoint counsel
      of the indemnifying party's choice at the indemnifying party's expense to
      represent the indemnified party in 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 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 Offerors and you
      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 Offerors and you may be subject in such proportion as is
      appropriate to reflect the relative benefits received by the Offerors on
      the one hand and by you on the other from the offering of the TARGETS;
      provided, however, that in no case shall you be responsible for any amount
      in excess of the underwriting discount or commission applicable to the
      TARGETS purchased by you hereunder. If the allocation provided by the
      immediately preceding sentence is unavailable for any reason, the Offerors
      and you severally shall contribute in such proportion as is appropriate to
      reflect not only such relative benefits but also the relative fault of the
      Offerors on the one hand and of you on the 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 Offerors shall
      be deemed to be equal to the total net proceeds from the offering (before
      deducting expenses) received by the Trust, and benefits received by you
      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
      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 Offerors on the one hand or you 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 Offerors and you 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 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 you within the
      meaning of either the Act or the Exchange Act and each director, officer,
      employee and agent of you shall have the same rights to contribution as
      you, as Underwriter, and each person who controls the Company, the
      Guarantor or the Trust, as applicable, within the meaning of either the
      Act or the Exchange Act, each officer of the Company or the Guarantor, as
      applicable, and each trustee of the Trust who shall have signed the
      Registration Statement, and each director of the Company or the Guarantor,
      as applicable, shall have the same rights to contribution as the Company,
      the



      Guarantor or the Trust, as applicable, subject in each case to the
      applicable terms and conditions of this paragraph (d).

            9. Termination. This Agreement shall be subject to termination in
your absolute discretion, by notice given to the Offerors prior to delivery of
and payment for the TARGETS, if at any time prior to such time (i) trading in
the Company's or the Guarantor'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 your sole judgment, as Underwriter, impractical or inadvisable to proceed
with the offering or delivery of the TARGETS as contemplated by the Prospectus
(exclusive of any supplement thereto).

            10. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company, the Guarantor, the Trust or their respective officers (or, in the case
of the Trust, trustees) and of you, as Underwriter, 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 you, as Underwriter, or the Company,
the Guarantor and the Trust or any of the officers, directors, employees, agents
or controlling persons (and, in the case of the Trust, trustees) referred to in
Section 8 hereof, and will survive delivery of and payment for the TARGETS. The
provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

            11. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Underwriter, will be mailed,
delivered or telefaxed to the Citigroup Global Markets Inc. General Counsel (fax

            12. 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 (and, in the case of the Trust,
trustees) referred to in Section 8 hereof, and no other person will have any
right or obligation hereunder.

            13. 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.
