Dear Sirs:

     The undersigned, Nuveen Insured Dividend Advantage Municipal Fund, a
Massachusetts business trust (the "Fund"), and Nuveen Advisory Corp., a Delaware
corporation (the "Manager"), address you as Underwriters and as the
representatives (the "Representatives") of each of the other persons, firms and
corporations, if any, listed in Schedule I hereto (herein collectively called
"Underwriters"). The Fund proposes to issue and sell an aggregate of _________
shares (the "Firm Shares") of its common shares of beneficial interest, $.01 par
value per share (the "Common Shares"), to the several Underwriters. The Fund
also proposes to sell to the Underwriters, upon the terms and conditions set
forth in Section 2 hereof, up to an additional _______ Common Shares (the
"Additional Shares"). The Firm Shares and Additional Shares are hereinafter
collectively referred to as the "Shares".

<PAGE>

     The Fund and the Manager wish to confirm as follows their agreements with
you and the other several Underwriters on whose behalf you are acting in
connection with the several purchases of the Shares by the Underwriters.

     The Fund is entering into an investment management agreement with the
Manager dated February 20, 2002, an exchange traded fund custody agreement with
JPMorgan Chase Bank dated February 19, 2002 and a shareholder transfer agency
agreement with JPMorgan Chase Bank dated February 19, 2002 and such agreements
are herein referred to as the "Management Agreement", the "Custodian Agreement"
and the "Transfer Agency Agreement", respectively. Collectively, the Management
Agreement, the Custodian Agreement and the Transfer Agency Agreement are herein
referred to as the "Fund Agreements". This Underwriting Agreement is herein
referred to as the "Agreement".

     1.   Registration Statement and Prospectus. The Fund has prepared and filed
          -------------------------------------
with the Securities and Exchange Commission (the "Commission") in accordance
with the provisions of the Securities Act of 1933, as amended (the "1933 Act"),
the Investment Company Act of 1940, as amended (the "1940 Act"), and the rules
and regulations of the Commission under the 1933 Act (the "1933 Act Rules and
Regulations") and the 1940 Act (the "1940 Act Rules and Regulations" and
together with the 1933 Act Rules and Regulations, the "Rules and Regulations") a
registration statement on Form N-2 (File No. 333-59770) under the 1933 Act and
the 1940 Act and may pursuant to the Rules and Regulations prepare and file an
additional registration statement relating to a portion of the Shares pursuant
to Rule 462(b) of the 1933 Act Rules and Regulations (collectively, the
"registration statement"), including a prospectus (including any statement of
additional information) relating to the Shares and a notification of
registration of the Fund as an investment company under the 1940 Act on Form
N-8A (the "1940 Act Notification"). The term "Registration Statement" as used in
this Agreement means the registration statement (including all financial
schedules and exhibits), as amended at the time it becomes effective under the
1933 Act or, if the registration statement became effective under the 1933 Act
prior to the execution of this Agreement, as amended or supplemented, prior to
the execution of this Agreement and includes any information deemed to be
included by Rule 430A under the 1933 Act Rules and Regulations. If it is
contemplated, at the time this Agreement is executed, that a post-effective
amendment to the registration statement will be filed under the 1933 Act and
must be declared effective before the offering of the Shares may commence, the
term "Registration Statement" as used in this Agreement means the registration
statement as amended by said post-effective amendment. The term "Prospectus" as
used in this Agreement means the prospectus (including the statement of
additional information) in the form included in the Registration Statement or,
if the prospectus (including the statement of additional information) included
in the Registration Statement omits information in reliance on Rule 430A and
such information is included in a prospectus (including the statement of
additional information) filed with the Commission pursuant to Rule 497(h) under
the 1933 Act Rules and Regulations, the term "Prospectus" as used in this
Agreement means the prospectus (including the statement of additional
information) in the form included in the Registration Statement as supplemented
by the addition of the information contained in the prospectus (including the
statement of additional information) filed with the Commission pursuant to Rule
497(h). The term "Prepricing Prospectus" as used in this Agreement means the
prospectus (including the

                                       2

<PAGE>

statement of additional information) subject to completion in the form included
in the registration statement at the time of the initial filing of the
registration statement with the Commission and as such prospectus (including the
statement of additional information) shall have been amended from time to time
prior to the date of the Prospectus, together with any other prospectus
(including any other statement of additional information) relating to the Fund
other than the Prospectus.

     The Fund has furnished the Representatives with copies of such registration
statement, each amendment to such registration statement filed with the
Commission and each Prepricing Prospectus.

     2.   Agreements to Sell and Purchase. The Fund hereby agrees, subject to
          -------------------------------
all the terms and conditions set forth herein, to issue and to sell to each
Underwriter and, upon the basis of the representations, warranties and
agreements of the Fund and the Manager herein contained and subject to all of
the other terms and conditions set forth herein, each Underwriter agrees,
severally and not jointly, to purchase from the Fund at a purchase price per
share of $14.325 per Share (the "purchase price per share"), the number of Firm
Shares set forth opposite the name of such Underwriter in Schedule I hereto (or
such number of Firm Shares increased as set forth in Section 10 hereof).

     The Fund also agrees, subject to all the terms and conditions set forth
herein, to issue and to sell to the Underwriters and, upon the basis of the
representations, warranties and agreements of the Fund and the Manager herein
contained and subject to all the terms and conditions set forth herein, the
Underwriters shall have the right to purchase from the Fund, at the purchase
price per share, pursuant to an option (the "over-allotment option") which may
be exercised at any time and from time to time prior to 9:00 P.M., New York City
time, on the 45th day after the date of the Prospectus (or if such 45th day
shall be a Saturday or a Sunday or a holiday, on the next business day
thereafter when the New York Stock Exchange (the "NYSE") is open for trading) up
to an aggregate of _______ Additional Shares. Additional Shares may be purchased
solely for the purpose of covering over-allotments made in connection with the
offering of the Firm Shares. Upon any exercise of the over-allotment option,
upon the basis of the representations, warranties and agreements of the Fund and
the Manager herein contained and subject to all of the other terms and
conditions set forth herein, each Underwriter agrees, severally and not jointly,
to purchase from the Fund the number of Additional Shares (subject to such
adjustments as you may determine to avoid fractional shares) which bears the
same proportion to the number of Additional Shares to be purchased by the
Underwriters as the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule I (or such number of Firm Shares increased as set forth
in Section 10 hereof) bears to the aggregate number of Firm Shares.

     3.   Terms of Public Offering. The Fund and the Manager have been advised
          ------------------------
by you that the Underwriters propose to make a public offering of their
respective portions of the Firm Shares as soon after the Registration Statement
and this Agreement have become effective as in your judgment is advisable and
initially to offer the Firm Shares upon the terms set forth in the Prospectus.

             (b) Delivery to the Underwriters of and payment to the Fund for any
     Additional Shares to be purchased by the Underwriters shall be made at the
     aforementioned office of Salomon Smith Barney Inc. at such time on such
     date (an "Option Closing Date"), which may be the same as the Closing Date,
     but shall in no event be earlier than the Closing Date nor earlier than two
     nor later than three business days after the giving of the notice
     hereinafter referred to, as shall be specified in a written notice from you
     on behalf of the Underwriters to the Fund of the Underwriters'
     determination to purchase a number, specified in said notice, of Additional
     Shares. The place of closing for any Additional Shares and the Option
     Closing Date for such Additional Shares may be varied by agreement between
     you and the Fund.

             (c) Certificates for the Firm Shares and for any Additional Shares
     shall be registered in such names and in such denominations as you shall
     request prior to 1:00 P.M., New York City time, (i) in respect of the Firm

     Closing Date or any Option Closing Date, as the case may be. The
     certificates evidencing the Firm Shares and any Additional Shares to be
     purchased hereunder shall be delivered to you on the Closing Date or the
     Option Closing Date, as the case may be, against payment of the purchase
     price therefor in same-day funds to the order of the Fund.

     5.   Agreements of the Fund and the Manager. The Fund and the Manager,
          --------------------------------------
jointly and severally, agree with the several Underwriters as follows:

             (a) If, at the time this Agreement is executed and delivered, it is
     necessary for the Registration Statement or a post-effective amendment
     thereto to be declared effective under the 1933 Act before the offering of
     the Firm Shares may commence, the Fund will use its reasonable best efforts
     to cause the Registration Statement or such post-effective amendment to
     become effective under the 1933 Act as soon as possible. If the
     Registration Statement has become effective and the Prospectus contained
     therein omits certain information at the time of effectiveness pursuant to
     Rule 430A of the 1933 Act Rules and Regulations, the Fund will file a
     prospectus including such information pursuant to Rule 497(h) of the 1933
     Act Rules and Regulations, as promptly as practicable, but no later than
     the second business day following the earlier of the date of the
     determination of the offering price of the Shares or the date the
     Prospectus is first

                                        4

<PAGE>

     used after the effective date of the Registration Statement. If the
     Registration Statement has become effective and the Prospectus contained
     therein does not so omit such information, the Fund will file a Prospectus
     pursuant to Rule 497 (c) or (j) of the 1933 Act Rules and Regulations as
     promptly as practicable, but no later than the fifth business day following
     the date of the later of the effective date of the Registration Statement
     or the commencement of the public offering of the Shares after the
     effective date of the Registration Statement. The Fund will advise you
     promptly and, if requested by you, will confirm such advice in writing (i)
     when the Registration Statement or such post-effective amendment has become
     effective, (ii) when the Prospectus has been timely filed pursuant to Rule
     497(c) or Rule 497(h) of the 1933 Act Rules and Regulations or the
     certification permitted pursuant to Rule 497(j) of the 1933 Act Rules and
     Regulations has been timely filed, whichever is applicable.

             (b) The Fund will advise you promptly and, if requested by you,
     will confirm such advice in writing: (i) of any request made by the
     Commission for amendment of or a supplement to the Registration Statement,
     any Prepricing Prospectus or the Prospectus (or any amendment or supplement
     to any of the foregoing) or for additional information, (ii) of the
     issuance by the Commission, the National Association of Securities Dealers,
     Inc. (the "NASD"), any state securities commission, any national securities
     exchange, any arbitrator, any court or any other governmental, regulatory,
     self-regulatory or administrative agency or any official suspending the
     effectiveness of the Registration Statement, prohibiting or suspending the
     use of the Prospectus, any Prepricing Prospectus or any sales material (as
     hereinafter defined), of any notice pursuant to Section 8(e) of the 1940
     Act, of the suspension of qualification of the Shares for offering or sale
     in any jurisdiction, or the initiation or contemplated initiation of any
     proceeding for any such purposes, (iii) of receipt by the Fund, the
     Manager, any affiliate of the Fund or the Manager or any representative or
     attorney of the Fund or the Manager of any other material communication
     from the Commission, the NASD, any state securities commission, any
     national securities exchange, any arbitrator, any court or any other
     governmental, regulatory, self-regulatory or administrative agency or any
     official relating to the Fund (if such communication relating to the Fund
     is received by such person within three years after the date of this
     Agreement), the Registration Statement, the 1940 Act Notification, the
     Prospectus, any Prepricing Prospectus, any sales material (as hereinafter
     defined) (or any amendment or supplement to any of the foregoing), this
     Agreement or any of the Fund Agreements and (iv) within the period of time
     referred to in paragraph (f) below, of any material adverse change in the
     condition (financial or other), business, prospects, properties, net assets
     or results of operations of the Fund or the Manager or of the happening of
     any event which makes any statement of a material fact made in the
     Registration Statement, the Prospectus, any Prepricing Prospectus or any
     sales material (as herein defined) (or any amendment or supplement to any
     of the foregoing) untrue or which requires the making of any additions to
     or changes in the Registration Statement, the Prospectus, any Prepricing
     Prospectus or any sales materials (as herein defined) (or any amendment or
     supplement to any of the foregoing) in order to state a material fact
     required by the 1933 Act, the 1940 Act or the Rules and Regulations to be
     stated therein or necessary in order to make the statements therein (in the
     case of a prospectus, in light

                                        5

<PAGE>

     of the circumstances under which they were made) not misleading or of the
     necessity to amend or supplement the Registration Statement, the
     Prospectus, any Prepricing Prospectus or any sales material (as herein
     defined) (or any amendment or supplement to any of the foregoing) to comply
     with the 1933 Act, the 1940 Act, the Rules and Regulations or any other law
     or order of any court or regulatory body. If at any time the Commission,
     the NASD, any state securities commission, any national securities
     exchange, any arbitrator, any court or any other governmental, regulatory,
     self-regulatory or administrative agency or any official shall issue any
     order suspending the effectiveness of the Registration Statement,
     prohibiting or suspending the use of the Prospectus, any Prepricing
     Prospectus or any sales material (as hereinafter defined) (or any amendment
     or supplement to any of the foregoing) or suspending the qualification of
     the Shares for offering or sale in any jurisdiction, the Fund will use its
     reasonable best efforts to obtain the withdrawal of such order at the
     earliest possible time.

             (c) The Fund will furnish to you, without charge, three signed
     copies of the registration statement and the 1940 Act Notification as
     originally filed with the Commission and of each amendment thereto,
     including financial statements and all exhibits thereto (except any
     post-effective amendment required by Rule 8b-16 of the 1940 Act Rules and
     Regulations which is filed with the Commission after the later of (x) one
     year from the date of this Agreement and (y) the date on which the
     distribution of the Shares is completed) and will also furnish to you,
     without charge, such number of conformed copies of the registration
     statement as originally filed and of each amendment thereto (except any
     post-effective amendment required by Rule 8b-16 of the 1940 Act Rules and
     Regulations which is filed with the Commission after the later of (x) one
     year from the date of this Agreement and (y) the date on which the
     distribution of the Shares is completed), with or without exhibits, as you
     may reasonably request.

             (d) The Fund will not (i) file any amendment to the Registration
     Statement or make any amendment or supplement to the Prospectus, any
     Prepricing Prospectus or any sales material (as hereinafter defined) (or
     any amendment or supplement to any of the foregoing) of which you shall not
     previously have been advised or to which you shall reasonably object within
     a reasonable time after being so advised or (ii) so long as, in the opinion
     of counsel for the Underwriters, a Prospectus is required to be delivered
     in connection with sales by any Underwriter or dealer, file any
     information, documents or reports pursuant to the Securities Exchange Act
     of 1934, as amended (the "1934 Act"), without delivering a copy of such
     information, documents or reports to you, as Representatives of the
     Underwriters, prior to or concurrently with such filing.

             (e) Prior to the execution and delivery of this Agreement, the Fund
     has delivered to you, without charge, in such quantities as you have
     reasonably requested, copies of each form of any Prepricing Prospectus. The
     Fund consents to the use, in accordance with the provisions of the 1933 Act
     and with the securities or Blue Sky laws of the jurisdictions in which the
     Shares are offered by the several Underwriters and by dealers, prior to the
     date of the Prospectus, of each Prepricing Prospectus so furnished by the
     Fund.

                                       6

<PAGE>

             (f) As soon after the execution and delivery of this Agreement as
     possible and thereafter from time to time, for such period as in the
     opinion of counsel for the Underwriters a prospectus is required by the
     1933 Act to be delivered in connection with sales of Shares by any
     Underwriter or dealer, the Fund will expeditiously deliver to each
     Underwriter and each dealer, without charge, as many copies of the
     Prospectus (and of any amendment or supplement thereto) as you may
     reasonably request. The Fund consents to the use of the Prospectus (and of
     any amendments or supplements thereto) in accordance with the provisions of
     the 1933 Act and with the securities or Blue Sky laws of the jurisdictions
     in which the Shares are offered by the several Underwriters and by all
     dealers to whom Shares may be sold, both in connection with the offering or
     sale of the Shares and for such period of time thereafter as the Prospectus
     is required by law to be delivered in connection with sales of Shares by
     any Underwriter or dealer. If during such period of time any event shall
     occur that in the judgment of the Fund or in the opinion of counsel for the
     Underwriters is required to be set forth in the Prospectus (as then amended
     or supplemented) or should be set forth therein in order to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading or if it is necessary to supplement or amend the
     Prospectus to comply with the 1933 Act, the 1940 Act, the Rules and
     Regulations or any other law, rule or regulation, the Fund will forthwith
     prepare and, subject to the provisions of paragraph (d) above, file with
     the Commission an appropriate amendment or supplement thereto and will
     expeditiously furnish to the Underwriters and dealers, without charge, such
     number of copies thereof as they shall reasonably request. In the event
     that the Prospectus is to be amended or supplemented, the Fund, if
     requested by you, will promptly issue a press release announcing or
     disclosing the matters to be covered by the proposed amendment or
     supplement.

             (g) The Fund will cooperate with you and with counsel for the
     Underwriters in connection with the registration or qualification of the
     Shares for offering and sale by the several Underwriters and by dealers
     under the securities or Blue Sky laws of such jurisdictions as you may
     designate and will file such consents to service of process or other
     documents necessary or appropriate in order to effect such registration or
     qualification; provided that in no event shall the Fund be obligated to
     qualify to do business in any jurisdiction where it is not now so qualified
     or to take any action which would subject it to service of process in
     suits, other than those arising out of the offering or sale of the Shares,
     in any jurisdiction where it is not now so subject.

             (h) The Fund will make generally available to its security holders
     an earnings statement, which need not be audited, covering a twelve-month
     period commencing after the effective date of the Registration Statement
     and ending not later than 15 months thereafter, as soon as practicable
     after the end of such period, which earnings statement shall satisfy the
     provisions of Section 11(a) of the 1933 Act and Rule 158 of the 1933 Act
     Rules and Regulations.

             (i) The Fund will comply with the undertaking set forth in
     paragraph 6 of Item 33 of Part C of the Registration Statement.

                                       7

<PAGE>

             (j) During the period of five years hereafter, the Fund will
     furnish to you (i) as soon as available, a copy of each report of the Fund
     mailed to shareholders or filed with the Commission and (ii) from time to
     time such other information concerning the Fund as you may reasonably
     request.

             (k) If this Agreement shall terminate or shall be terminated after
     execution pursuant to any provisions hereof (other than pursuant to the
     second paragraph of Section 10 hereof or by notice given by you terminating
     this Agreement pursuant to Section 10 or Section 11 hereof) or if this
     Agreement shall be terminated by the Underwriters because of any failure or
     refusal on the part of the Fund or the Manager to comply with the terms or
     fulfill any of the conditions of this Agreement, the Fund and the Manager,
     jointly and severally, agree to reimburse the Representatives for all
     out-of-pocket expenses (including fees and expenses of counsel for the
     Underwriters) incurred by you in connection herewith, but the Fund and the
     Manager shall in no event be liable for any internal cost of the
     Underwriters or any loss of anticipated profits or speculative,
     consequential or similar damages for such termination.

             (l) The Fund will direct the investment of the net proceeds of the
     offering of the Shares in such a manner as to comply with the investment
     objectives, policies and restrictions of the Fund as described in the
     Prospectus.

             (m) The Fund will file the requisite copies of the Prospectus with
     the Commission in a timely fashion pursuant to Rule 497(c) or Rule 497(h)
     of the 1933 Act Rules and Regulations, whichever is applicable or, if
     applicable, will file in a timely fashion the certification permitted by
     Rule 497(j) of the 1933 Act Rules and Regulations and will advise you of
     the time and manner of such filing.

             (n) Except as provided in this Agreement or pursuant to any
     dividend reinvestment plan of the Fund in effect on the date hereof, the
     Fund will not sell, contract to sell or otherwise dispose of, any Common
     Shares or any securities convertible into or exercisable or exchangeable
     for Common Shares or grant any options or warrants to purchase Common
     Shares, for a period of 180 days after the date of the Prospectus, without
     the prior written consent of Salomon Smith Barney Inc.

             (o) Except as stated in this Agreement and in the Prospectus,
     neither the Fund nor the Manager has taken, nor will it take, directly or
     indirectly, any action designed to or that might reasonably be expected to
     cause or result in stabilization or manipulation of the price of the Common
     Shares.

             (p) The Fund will use its reasonable best efforts to have the
     Common Shares listed, subject to notice of issuance, on the American Stock
     Exchange (the "AMEX") concurrently with the effectiveness of the
     Registration Statement and to comply with the rules and regulations of such
     exchange.

     6.   Representations and Warranties of the Fund and the Manager. The Fund
          ----------------------------------------------------------
and the Manager, jointly and severally, represent and warrant to each
Underwriter that:

                                       8

<PAGE>

             (a) Each Prepricing Prospectus included as part of the registration
     statement as originally filed or as part of any amendment or supplement
     thereto or filed pursuant to Rule 497 of the 1933 Act Rules and
     Regulations, complied when so filed in all material respects with the
     provisions of the 1933 Act, the 1940 Act and the Rules and Regulations.

             (b) The Registration Statement, in the form in which it became or

     to either of them), the Fund has not incurred any liability or obligation,
     direct or contingent that is material to the Fund and there has not been

     offering of the Shares in such a manner as to comply with the requirements

          (a) The Fund and the Manager, jointly and severally, agree to
     indemnify and hold harmless each of you and each other Underwriter and each
     person, if any, who controls any Underwriter within the meaning of Section
     15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and
     all losses, claims, damages, liabilities and expenses, joint or several
     (including reasonable costs of investigation) arising out of or based upon
     any untrue statement or alleged untrue statement of a material fact
     contained in the Registration Statement, the Prospectus, any Prepricing
     Prospectus, any sales material (or any amendment or supplement to any of
     the foregoing) or arising out of or based upon any omission or alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statements therein (in the case of a prospectus, in
     light of the circumstances under which they were made) not misleading,
     except insofar as such losses, claims, damages, liabilities or expenses
     arise out of or are based upon any untrue statement or omission or alleged
     untrue statement or omission which has been made therein or omitted
     therefrom in reliance upon and in conformity with the information relating
     to such Underwriters furnished in writing to the Fund by or on behalf of
     any Underwriter through you expressly for use in connection therewith;
     provided, however, that the foregoing indemnity with respect to the
     Registration Statement, the Prospectus or any Prepricing Prospectuses (or
     any amendment or supplement to any of the foregoing) shall not inure to the
     benefit of any Underwriter from whom the person asserting any loss, claim,
     damage, liability or expense purchased Shares, if it is shown that a copy
     of the Prospectus, as then amended or supplemented, which would have cured
     any defect giving rise to such loss, claim, damage, liability or expense
     was not sent or delivered to such person by or on behalf of such
     Underwriter, if required by law to be so delivered, at or prior to the
     confirmation of the sale of such Shares to such person and such Prospectus,
     amendments and supplements had been provided by the Fund to the
     Underwriters in the requisite quantity and on a timely basis to permit
     proper delivery. The foregoing indemnity agreement shall be in addition to
     any liability which the Fund or the Manager may otherwise have.

          (b) If any action, suit or proceeding shall be brought against any
     Underwriter or any person controlling any Underwriter in respect of which
     indemnity may be sought

     against the Fund or the Manager, such Underwriter or such controlling
     person shall promptly notify the Fund or the Manager and the Fund or the
     Manager shall assume the defense thereof, including the employment of
     counsel and the payment of all fees and expenses. Such Underwriter or any
     such controlling person shall have the right to employ separate counsel in
     any such action, suit or proceeding and to participate in the defense
     thereof, but the fees and expenses of such counsel shall be at the expense
     of such Underwriter or controlling person unless (i) the Fund or the
     Manager have agreed in writing to pay such fees and expenses, (ii) the Fund
     and the Manager have failed within a reasonable time to assume the defense
     and employ counsel or (iii) the named parties to any such action, suit or
     proceeding (including any impleaded parties) include both such Underwriter
     or such controlling person and the Fund or the Manager and such Underwriter
     or such controlling person shall have been advised by its counsel that
     representation of such indemnified party and the Fund or the Manager by the
     same counsel would be inappropriate under applicable standards of
     professional conduct (whether or not such representation by the same
     counsel has been proposed) due to actual or potential differing interests
     between them (in which case the Fund and the Manager shall not have the
     right to assume the defense of such action, suit or proceeding on behalf of
     such Underwriter or such controlling person). It is understood, however,
     that the Fund and the Manager shall, in connection with any one such
     action, suit or proceeding or separate but substantially similar or related
     actions, suits or proceedings in the same jurisdiction arising out of the
     same general allegations or circumstances be liable for the reasonable fees
     and expenses of only one separate firm of attorneys (in addition to any
     local counsel if there is any action, suit or proceeding in more than one
     jurisdiction) at any time for all such Underwriters and controlling persons
     not having actual or potential differing interests with you or among
     themselves, which firm shall be designated in writing by Salomon Smith
     Barney Inc. and that, subject to the requirements of 1940 Act Release No.
     11330, all such fees and expenses shall be reimbursed promptly as they are
     incurred. The Fund and the Manager shall not be liable for any settlement
     of any such action, suit or proceeding effected without the written consent
     of the Fund or the Manager, but if settled with such written consent or if
     there be a final judgment for the plaintiff in any such action, suit or
     proceeding, the Fund and the Manager agree to indemnify and hold harmless
     any Underwriter, to the extent provided in the preceding paragraph, and any
     such controlling person from and against any loss, liability, damage or
     expense by reason by such settlement or judgment.

          (c) Each Underwriter agrees, severally and not jointly, to indemnify
     and hold harmless the Fund and the Manager, their trustees, directors, any
     officers of the Fund who sign the Registration Statement and any person who
     controls the Fund or the Manager within the meaning of Section 15 of the
     1933 Act or Section 20 of the 1934 Act, to the same extent as the foregoing
     indemnity from the Fund and the Manager to each Underwriter, but only with
     respect to information relating to such Underwriter furnished in writing by
     or on behalf of such Underwriter through you expressly for use in the
     Registration Statement or the Prospectus (or any amendment or supplement to
     either of them). If any action, suit or proceeding shall be brought against
     the Fund or the Manager, any of their trustees, directors, any such officer
     or any such controlling person, based on

                                       17

<PAGE>

     the Registration Statement or the Prospectus (or any amendment or
     supplement to either of them) and in respect of which indemnity may be
     sought against any Underwriter pursuant to this paragraph (c), such
     Underwriter shall have the rights and duties given to the Fund by paragraph
     (b) above (except that if the Fund or the Manager shall have assumed the
     defense thereof such Underwriter shall not be required to do so, but may
     employ separate counsel therein and participate in the defense thereof, but
     the fees and expenses of such counsel shall be at such Underwriter's
     expense) and the Fund and the Manager, their trustees, directors, any such
     officer and any such controlling person shall have the rights and duties
     given to the Underwriters by paragraph (b) above. The foregoing indemnity
     agreement shall be in addition to any liability which the Underwriters may
     otherwise have.

          (d) If the indemnification provided for in this Section 8 is
     unavailable to an indemnified party under paragraphs (a) or (c) hereof in
     respect of any losses, claims, damages, liabilities or expenses referred to
     therein, then an indemnifying party, in lieu of indemnifying such
     indemnified party, shall contribute to the amount paid or payable by such
     indemnified party as a result of such losses, claims, damages, liabilities
     or expenses (i) in such proportion as is appropriate to reflect the
     relative benefits received by the Fund and the Manager on the one hand
     (treated jointly for this purpose as one person) and the Underwriters on
     the other hand from the offering of the Shares 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 Fund and
     the Manager on the one hand (treated jointly for this purpose as one
     person) and of the Underwriters on the other hand in connection with the
     statements or omissions which resulted in such losses, claims, damages,
     liabilities or expenses, as well as any other relevant equitable
     considerations. The relative benefits received by the Fund and the Manager
     on the one hand (treated jointly for this purpose as one person) and the
     Underwriters on the other hand shall be deemed to be in the same proportion
     as the total net proceeds from the offering (before deducting expenses)
     received by the Fund as set forth in the table on the cover page of the
     Prospectus bear to the total payments received by the Underwriters with
     respect to the Firm Shares as set forth in the table on the cover page of
     the Prospectus. The relative fault of the Fund and the Manager on the one
     hand (treated jointly for this purpose as one person) and of the
     Underwriters on the other hand 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 Fund and the Manager on the one hand
     (treated jointly for this purpose as one person) or by the Underwriters on
     the other hand and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission.

          (e) The Fund, the Manager and the Underwriters agree that it would not
     be just and equitable if contribution pursuant to this Section 8 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 paragraph
     (d) above. The amount paid or payable by an indemnified party as

                                       18

<PAGE>

     a result of the losses, claims, damages, liabilities and expenses referred
     to in paragraph (d) above 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 defending any such
     action, suit or proceeding. Notwithstanding the provisions of this Section
     8, no Underwriter shall be required to contribute any amount in excess of
     the amount by which the total price of the Shares underwritten by it and
     distributed to the public exceeds the amount of any damages which such
     Underwriter has otherwise been required to pay by reason of such untrue or
     alleged untrue statement or omission or alleged omission. No person guilty
     of fraudulent misrepresentation (within the meaning of Section 11(f) of the
     1933 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 Section 8 are several in proportion to the
     respective number of Firm Shares set forth opposite their names in Schedule
     I (or such numbers of Firm Shares increased as set forth in Section 10
     hereof) and not joint.

          (f) No indemnifying party shall, without the prior written consent of
     the indemnified party, effect any settlement of any pending or threatened
     action, suit or 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 includes an unconditional
     release of such indemnified party from all liability from claimants on
     claims that are the subject matter of such action, suit or proceeding.

          (g) Any losses, claims, damages, liabilities or expenses for which an
     indemnified party is entitled to indemnification or contribution under this
     Section 8 shall be paid by the indemnifying party to the indemnified party
     as such losses, claims, damages, liabilities or expenses are incurred. The
     indemnity and contribution agreements contained in this Section 8 and the
     representations and warranties of the Fund and the Manager set forth in
     this Agreement shall remain operative and in full force and effect,
     regardless of (i) any investigation made by or on behalf of any Underwriter
     or any person controlling any Underwriter, the Fund, the Manager or their
     trustees, directors or officers or any person controlling the Fund or the
     Manager, (ii) acceptance of any Shares and payment therefor hereunder and
     (iii) any termination of this Agreement. A successor to any Underwriter or
     to the Fund, the Manager or their trustees, directors or officers or any
     person controlling any Underwriter, the Fund or the Manager shall be
     entitled to the benefits of the indemnity, contribution and reimbursement
     agreements contained in this Section 8.

     9. Conditions of Underwriters' Obligations. The several obligations of the
        ---------------------------------------
Underwriters to purchase any Shares hereunder are subject to, in the good faith
judgment of the Underwriters, the accuracy of and compliance with the
representations, warranties and agreements of and by the Fund and the Manager
contained herein on and as of the date hereof, the date on which the
Registration Statement becomes or became effective, the date of the Prospectus
(and of any amendment or supplement thereto), the Closing Date and, with respect

                                       19

<PAGE>

the Manager or any of their officers in any certificate delivered to the
Representatives or their counsel pursuant to this Agreement and to the following
conditions:

          (a) If, at the time this Agreement is executed and delivered, it is
     necessary for the Registration Statement or a post-effective amendment
     thereto to be declared effective before the offering of the Shares may
     commence, the Registration Statement or such post-effective amendment shall
     have become effective not later than 5:30 p.m., New York City time, on the
     date hereof or at such later date and time as shall be consented to in
     writing by you and all filings, if any, required by Rules 497 and 430A
     under the 1933 Act Rules and Regulations shall have been timely made; no
     order suspending the effectiveness of the Registration Statement shall have
     been issued and no proceeding for that purpose shall have been instituted
     or, to the knowledge of the Fund, the Manager or any Underwriter,
     threatened by the Commission and any request of the Commission for
     additional information (to be included in the Registration Statement or the
     Prospectus or otherwise) shall have been complied with to your
     satisfaction.

          (b) You shall have received on the Closing Date an opinion of Bell,
     Boyd & Lloyd LLC, special counsel for the Fund and Manager, dated the
     Closing Date and addressed to you, as Representatives of the several
     Underwriters, to the effect that:

              (i)   The Fund is a business trust duly established, validly
          existing and in good standing under the laws of The Commonwealth of
          Massachusetts with full power and authority to own, lease and operate
          its properties and to conduct its business as described in the
          Registration Statement and the Prospectus (and any amendment or
          supplement thereto through the date of the opinion) and is duly
          registered and qualified to conduct its business and is in good
          standing in each jurisdiction where the nature of its properties or
          the conduct of its business requires such registration or
          qualification, except where the failure so to register or to qualify
          does not have a material, adverse effect on the condition (financial
          or other), business, properties, net assets or results of operations
          of the Fund;

              (ii)  The authorized and outstanding capital stock of the Fund is
          as set forth in the Registration Statement and Prospectus (or any
          amendment or supplement thereto through the date of the opinion); and
          the description of the authorized capital stock of the Fund contained
          in the Prospectus (or any amendment or supplement thereto through the
          date of the opinion) under the caption "Description of Shares"
          conforms in all material respects as to legal matters to the terms
          thereof contained in the Fund's Declaration of Trust;

              (iii) All of the shares of capital stock of the Fund outstanding
          prior to the issuance of the Shares have been duly authorized and
          validly issued and are fully paid and nonassessable, except that, as
          described in the Prospectus under the heading, "Certain Provisions in
          the Declaration of Trust," shareholders of the Fund may under certain
          circumstances be held personally liable for its obligations;

                                       20

<PAGE>

              (iv)   The Shares have been duly authorized and, when issued and
          delivered to the Underwriters against payment therefor in accordance
          with the terms hereof, will be validly issued, fully paid and
          nonassessable and not subject to any preemptive rights that entitle or
          will entitle any person to acquire any Shares upon the issuance
          thereof by the Fund, except that, as described in the Prospectus under
          the heading, "Certain Provisions in the Declaration of Trust,"
          shareholders of the Fund may under certain circumstances be held
          personally liable for its obligations;

              (v)    The form of certificate for the Shares is in due and proper
          form and complies with the requirements of all applicable laws and the
          AMEX;

              (vi)   The Fund has the power and authority to enter into this
          Agreement and the Fund Agreements and to issue, sell and deliver the
          Shares to the Underwriters as provided herein and this Agreement and
          each of the Fund Agreements have been duly authorized, executed and
          delivered by the Fund and assuming due authorization, execution and
          delivery by the other parties thereto and that the performance of the
          Underwriting Agreement and the Fund Agreements by the other parties
          thereto will not violate law, agreements to which such other parties
          or their properties are subject or orders applicable to such other
          parties, constitute the valid, legal and binding agreements of the
          Fund, enforceable against the Fund in accordance with their terms,
          except as enforcement of rights to indemnity hereunder may be limited
          by Federal or state securities laws or principles of public policy and
          subject to the qualification that the enforceability of the Fund's
          obligations hereunder and thereunder may be limited by bankruptcy,
          insolvency, reorganization, moratorium and other laws relating to or
          affecting creditors' rights generally and by general equitable
          principles, whether enforcement is considered in a proceeding in
          equity or at law;

              (vii)  This Agreement constitutes a valid, legal and binding
          agreement of the Manager, enforceable against the Manager in
          accordance with its terms, except as enforcement of rights to
          indemnity hereunder may be limited by Federal or state securities laws
          or principles of public policy and subject to the qualification that
          the enforceability of the Manager's obligations hereunder may be
          limited by bankruptcy, insolvency, reorganization, moratorium and
          other laws relating to or affecting creditors' rights generally and by
          general equitable principles, whether enforcement is considered in a
          proceeding in equity or at law;

              (viii) The Fund Agreements comply in all material respects with
          all applicable provisions of the 1933 Act, the 1940 Act, the Advisers
          Act, the Rules and Regulations and the Advisers Act Rules and
          Regulations;

              (ix)   The Fund is not in violation of its Declaration of Trust or
          By-Laws or to the best knowledge of such counsel after reasonable
          inquiry, is not in material default in the performance of any material
          obligation, agreement or condition contained in any bond, debenture,
          note or other evidence of

                                       21

<PAGE>

          indebtedness, except as may be disclosed in the Prospectus (and any
          amendment or supplement thereto);

              (x)   No consent, approval, authorization or order of or
          registration or filing with the Commission, the NASD, any state
          securities commission, any national securities exchange, any
          arbitrator, any court or any other governmental body, agency or
          regulatory, self-regulatory or administrative agency or any official
          is required on the part of the Fund (except as have been obtained
          under the 1933 Act and the 1934 Act or such as may be required under
          state securities or Blue Sky laws governing the purchase and
          distribution of the Shares) for the valid issuance and sale of the
          Shares to the Underwriters as contemplated by this Agreement,
          performance of the Fund Agreements or this Agreement by the Fund, the
          consummation by the Fund of the transactions contemplated thereby or
          hereby or the adoption of the Fund's Dividend Reinvestment Plan;

              (xi)  Neither the offer, sale or delivery of the Shares, the
          execution, delivery or performance of this Agreement or the Fund
          Agreements, compliance by the Fund with the provisions hereof or
          thereof, consummation by the Fund of the transactions contemplated
          hereby or thereby nor the adoption of the Fund's Dividend Reinvestment
          Plan violates the Declaration of Trust or By-Laws of the Fund or any
          material agreement, indenture, lease or other instrument to which the
          Fund is a party or by which it or any of its properties is bound that
          is an exhibit to the Registration Statement or that is known to such
          counsel after reasonable inquiry or, to the best of such counsel's
          knowledge after reasonable inquiry, will result in the creation or
          imposition of any material lien, charge or encumbrance upon any
          property or assets of the Fund, nor, to the best of such counsel's
          knowledge after reasonable inquiry, will any such action result in any
          violation of any existing material law, regulation, ruling (assuming
          compliance with all applicable state securities and Blue Sky laws),
          judgment, injunction, order or decree known to such counsel after
          reasonable inquiry, applicable to the Fund or any of its properties,
          except that, in the published opinion of the Commission, the
          indemnification provisions in this Agreement and the Fund Agreements,
          insofar as they relate to indemnification for liabilities arising
          under the 1933 Act, are against public policy as expressed in the 1933
          Act and therefore unenforceable;

              (xii) The Registration Statement and all post-effective
          amendments, if any, have become effective under the 1933 Act and, to
          the best knowledge of such counsel after reasonable inquiry, no order
          suspending the effectiveness of the Registration Statement has been
          issued and no proceedings for that purpose are pending before or
          contemplated by the Commission; and any filing of the Prospectus and
          any amendments or supplements thereto required pursuant to Rule 497 of
          the 1933 Act Rules and Regulations prior to the date of such opinion
          has been made in accordance with Rule 497;

                                       22

<PAGE>

               (xiii)  The Fund is duly registered with the Commission under the
          1940 Act as a closed-end management investment company and all action
          has been taken by the Fund as required by the 1933 Act and the 1940
          Act and the Rules and Regulations in connection with the issuance and
          sale of the Shares to make the public offering and consummate the sale
          of the Shares as contemplated by this Agreement;

               (xiv)   The statements made in the Registration Statement and the
          Prospectus (and any amendment or supplement to either of them through
          the date of the opinion) under the caption "Tax Matters" have been
          reviewed by such counsel and to the extent they describe or summarize
          tax laws, doctrines or practices of the United States, present a fair
          and accurate description or summary thereof as of the date of the
          opinion;

               (xv)    The statements in the Registration Statement and
          Prospectus (and any amendment or supplement to either of them through
          the date of the opinion), insofar as they are descriptions of
          contracts, agreements or other legal documents or refer to statements
          of law or legal conclusions, are accurate and present fairly the
          information required to be shown;

               (xvi)   The Registration Statement and the Prospectus (and any
          amendment or supplement to either of them through the date of the
          opinion) comply as to form in all material respects with the
          requirements of the 1933 Act, the 1940 Act and the Rules and
          Regulations (except that no opinion need be expressed as to the
          financial statements and the notes thereto and the schedules and other
          financial and statistical data included therein as to which such
          counsel need not express any opinion);

               (xvii)  To the best knowledge of such counsel after reasonable
          inquiry, (A) other than as described or contemplated in the Prospectus
          (or any amendment or supplement thereto through the date of the
          opinion), there are no actions, suits or other legal or governmental
          proceedings pending or expressly threatened against the Fund (through
          the date of the opinion) and (B) there are no material agreements,
          contracts, indentures, leases or other instruments that are required
          to be described in the Registration Statement or the Prospectus (or
          any amendment or supplement to either of them through the date of the
          opinion) or to be filed as an exhibit to the Registration Statement
          that are not described or filed as required, as the case may be;

               (xviii) To the best knowledge of such counsel after reasonable
          inquiry, the Fund is not in violation of any law, ordinance,
          administrative or governmental rule or regulation applicable to the
          Fund or of any decree of the Commission, the NASD, any state
          securities commission, any national securities exchange, any
          arbitrator, any court or any other governmental, regulatory,
          self-regulatory or administrative agency or any official having
          jurisdiction over the Fund; and

                                       23

<PAGE>

               (xix) The Shares are duly authorized for listing, subject to
          official notice of issuance, on the American Stock Exchange and the
          Fund's registration statement on Form 8-A under the 1934 Act is
          effective.

          Such counsel shall also state that although counsel has not
     undertaken, except as otherwise indicated in their opinion, to determine
     independently and does not assume any responsibility for, the accuracy or
     completeness of the statements in the Registration Statement, such counsel
     has participated in the preparation of the Registration Statement and the
     Prospectus, including review and discussion of the contents thereof, and
     nothing has come to the attention of such counsel that has caused it to
     believe that the Registration Statement, at the time the Registration
     Statement became effective or the Prospectus, as of its date and as of the
     Closing Date or the Option Closing Date, as the case may be, 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
     (in the case of a prospectus, in light of the circumstances under which
     they were made) not misleading or that any amendment or supplement to the
     Prospectus, as of the Closing Date or the Option Closing Date, contained an
     untrue statement of a material fact or omitted 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 (it being
     understood that such counsel need express no view with respect to the
     financial statements and the notes thereto and the schedules and other
     financial and statistical data included in the Registration Statement or
     the Prospectus).

          In rendering such opinion, such counsel may limit such opinion to
     matters involving the application of the laws of The Commonwealth of
     Massachusetts and the United States. To the extent they deem proper and to
     the extent specified in such opinion, such counsel may rely, as to matters
     involving the application of laws of The Commonwealth of Massachusetts,
     upon the opinion of Bingham Dana LLP or, as to the other matters, other

     expressly authorized by the opinion so relied upon and a copy of each such
     opinion is delivered to the Representatives and is, in form and substance,

       R. Zimmerman, Vice President, Assistant Secretary and General Counsel for

              (i)    The Manager is a corporation duly incorporated and validly
          existing in good standing under the laws of the State of Delaware with
          full corporate power and authority to own, lease and operate its

                                       24

<PAGE>

          place where the nature of its properties or the conduct of its
          business requires such registration or qualification, except where the
          failure so to register or to qualify does not have a material, adverse
          effect on the condition (financial or other), business, properties,
          net assets or results of operations of the Manager;

               (ii)   The Manager is duly registered with the Commission under
          the Advisers Act as an investment adviser and is not prohibited by the
          Advisers Act, the 1940 Act or the Rules and Regulations under such
          acts from acting for the Fund under the Management Agreement as
          contemplated by the Prospectus (and any amendment or supplement
          thereto);

               (iii)  The Manager has corporate power and authority to enter
          into this Agreement and the Management Agreement and this Agreement
          and the Management Agreement have been duly authorized, executed and
          delivered by the Manager and the Management Agreement is a valid,
          legal and binding agreement of the Manager, enforceable against the
          Manager in accordance with its terms, except as enforcement of rights
          to indemnity and contribution hereunder may be limited by Federal or
          state securities laws or principles of public policy and subject to
          the qualification that the enforceability of the Manager's obligations
          hereunder and thereunder may be limited by bankruptcy, insolvency,
          reorganization, moratorium and other laws relating to or affecting
          creditors' rights generally and by general equitable principles;

               (iv)   The Management Agreement complies in all material respects
          with all applicable provisions of the Advisers Act, the 1940 Act and
          the Advisers Act Rules and Regulations and the 1940 Act Rules and
          Regulations;

               (v)    Neither the execution and delivery by the Manager of this
          Agreement or the Management Agreement nor the consummation by the
          Manager of the transactions contemplated hereunder or thereunder
          constitutes or will constitute a breach of or a default under the
          Certificate of Incorporation or By-Laws of the Manager or any material
          agreement, indenture, lease or other instrument to which the Manager
          is a party or by which it or any of its properties is bound that is
          known to such counsel after reasonable inquiry, or will result in the
          creation or imposition of any material lien, charge or encumbrance
          upon any property or assets of the Manager, nor will any such action
          result in any violation of any existing material law, regulation,
          ruling (assuming compliance with all applicable state securities and
          Blue Sky laws), judgment, injunction, order or decree known to such
          counsel after reasonable inquiry, applicable to the Fund or any of its
          properties;

               (vi)   The description of the Manager and its business in the
          Prospectus (and any amendment or supplement thereto) complies in all
          material respects with all requirements of the 1933 Act, the 1940 Act
          and the Rules and Regulations;

                                       25

<PAGE>

               (vii)   To the best knowledge of such counsel after reasonable
          inquiry, other than as described or contemplated in the Prospectus
          (and any amendment or supplement thereto), there are no actions, suits
          or other legal or governmental proceedings pending or threatened
          against the Manager or to which the Manager or any of its property is
          subject which are required to be described in the Registration
          Statement or Prospectus (or any amendment or supplement to either of
          them);

               (viii)  The Manager owns, possesses or has obtained and currently
          maintains all governmental licenses, permits, consents, orders,
          approvals and other authorizations as are necessary for the Manager to
          carry on its business as contemplated in the Prospectus (and any
          amendment or supplement thereto); and

               (ix)    No material consent, approval, authorization or order of
          or registration or filing with any court, regulatory body,
          administrative or other governmental body, agency or official is
          required on the part of the Manager for the performance of this
          Agreement or the Management Agreement by the Manager or for the
          consummation by the Manager of the transactions contemplated hereby or
          thereby.

               Such counsel shall also state that although counsel has not
          undertaken, except as otherwise indicated in its opinion, to determine
          independently and does not assume any responsibility for, the accuracy
          or completeness of the statements in the Registration Statement, such
          counsel has participated in the preparation of the Registration
          Statement and the Prospectus, including review and discussion of the
          contents thereof and nothing has come to its attention that has caused
          it to believe that the Registration Statement at the time it became
          effective or the Prospectus, as of its date and as of the Closing Date
          or the Option Closing Date, as the case may be, 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 (in the case of a prospectus, in light of the circumstances
          under which they were made) not misleading or that any amendment or
          supplement to the Prospectus, as of the Closing Date or the Option
          Closing Date, contained an untrue statement of a material fact or
          omitted 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 (it being understood that such counsel need
          express no opinion with respect to the financial statements and the
          notes thereto and the schedules and other financial and statistical
          data included in the Registration Statement or the Prospectus).

               In rendering such opinion, counsel may limit such opinion to
          matters involving the application of the laws of the State of
          Illinois, the Delaware General Corporation Law statute and the laws of
          the United States and may rely upon an opinion or opinions, each dated
          the Closing Date, of other counsel retained by the Manager as to laws
          of any jurisdiction other than the United States, the State of

                                       26

<PAGE>

          Illinois and the Delaware General Corporation Law statute, provided
          that (X) each such local counsel is acceptable to the Representatives,
          (Y) such reliance is expressly authorized by each opinion so relied
          upon and a copy of each such opinion is delivered to the
          Representatives and is in form and substance satisfactory to them and
          their counsel and (Z) counsel shall state in his view that he believes
          that he and the Underwriters are justified in relying thereon.

          (d)  You shall have received on the Closing Date a comfort letter,
     substantially in the form heretofore approved by you, from Chapman and
     Cutler, special counsel to the Fund, dated the Closing Date and addressed
     to you, as Representatives of the several Underwriters, with respect to the
     information presented in Appendix B to the statement of additional
     information under the heading "Taxable Equivalent Yield Tables."

          (e)  That you shall have received on the Closing Date, an opinion,
     dated the Closing Date, of Simpson Thacher & Bartlett, counsel for the
     Underwriters, dated the Closing Date and addressed to you, as
     Representatives of the several Underwriters, with respect to such matters
     as the Underwriters may require and the Fund, the Manager and their
     respective counsels shall have furnished to such counsel such documents as
     they may request for the purpose of enabling them to pass upon such
     matters.

          (f)  That you shall have received letters addressed to you, as
     Representatives of the several Underwriters, and dated the date hereof and
     the Closing Date from Ernst & Young LLP, independent certified public
     accountants, substantially in the forms heretofore approved by you.

          (g)  (i) No order suspending the effectiveness of the Registration
     Statement or prohibiting or suspending the use of the Prospectus (or any
     amendment or supplement thereto) or any Prepricing Prospectus or any sales
     material shall have been issued and no proceedings for such purpose or for
     the purpose of commencing an enforcement action against the Fund, the
     Manager or, with respect to the transactions contemplated by the Prospectus
     (or any amendment or supplement thereto) and this Agreement, any
     Underwriter, may be pending before or, to the knowledge of the Fund, the
     Manager or any Underwriter or in the reasonable view of counsel to the
     Underwriters, shall be threatened or contemplated by the Commission at or
     prior to the Closing Date and that any request for additional information
     on the part of the Commission (to be included in the Registration
     Statement, the Prospectus or otherwise) be complied with to the
     satisfaction of the Representatives, (ii) there shall not have been any
     change in the capital stock of the Fund nor any material increase in debt
     of the Fund from that set forth in the Prospectus (and any amendment or
     supplement thereto) and the Fund shall not have sustained any material
     liabilities or obligations, direct or contingent, other than those
     reflected in the Prospectus (and any amendment or supplement thereto);
     (iii) since the date of the Prospectus there shall not have been any
     material, adverse change in the condition (financial or other), business,
     prospects, properties, net assets or results of operations of the Fund or
     the Manager; (iv) the Fund and the Manager must not have sustained any
     material loss or interference with its business from any court or from
     legislative or other governmental action, order or decree or from any other
     occurrence not described in the Registration Statement and the Prospectus
     (and any amendment or supplement to either of them); and (v) all of the
     representations and warranties of the Fund and the Manager contained in
     this Agreement shall be true and correct on and as of the date hereof and
     as of the Closing Date as if made on and as of the Closing Date.

<PAGE>

          (h)  Subsequent to the effective date of this Agreement, there shall
     not have occurred (i) any change or any development involving a prospective
     change in or affecting the condition (financial or other), business,
     prospects, properties, net assets or results of operations of the Fund or
     the Manager not contemplated by the Prospectus (and any amendment or
     supplement thereto), which in your opinion, as Representatives of the
     several Underwriters, would materially, adversely affect the market for the
     Shares or (ii)any event or development relating to or involving the Fund,
     the Manager or any officer or trustee or director of the Fund or the
     Manager which makes any statement of a material fact made in the Prospectus
     (or any amendment or supplement thereto) untrue or which, in the opinion of
     the Fund and its counsel or the Underwriters and their counsel, requires
     the making of any addition to or change in the Prospectus (or any amendment
     or supplement thereto) in order to state a material fact required by the
     1933 Act, the 1940 Act, the Rules and Regulations or any other law to be
     stated therein or necessary in order to make the statements therein (in the
     case of a prospectus, in light of the circumstances under which they were
     made) not misleading, if amending or supplementing the Prospectus (or any
     amendment or supplement thereto) to reflect such event or development
     would, in your opinion, as Representatives of the several Underwriters,
     materially, adversely affect the market for the Shares.

          (i)  That neither the Fund nor the Manager shall have failed at or
     prior to the Closing Date to have performed or complied with any of the
     agreements herein contained and required to be performed or complied with
     by them at or prior to the Closing Date.

          (j)  That you shall have received on the Closing Date a certificate,

     (i) the signers have carefully examined the Registration Statement, the
     Prospectus (and any amendments or supplements to either of them) and this
     Agreement, (ii) the representations and warranties of the Fund (with
     respect to the certificates from such Fund officers) and the
     representations of the Manager (with respect to the certificates from such

     further certificates, documents and opinions of counsel as you shall
     reasonably request (including certificates of officers of the Fund and the
     Manager).

          All such opinions, certificates, letters and other documents will be

          Any certificate or document signed by any officer of the Fund or the
     Manager and delivered to you, as Representatives of the Underwriters or to

     Fund or the Manager to each Underwriter as to the statements made therein.

          The several obligations of the Underwriters to purchase Additional
     Shares hereunder are subject to (i) the accuracy of and compliance with the

     termination of this Agreement pursuant to Section 11 hereof if they existed
     on or prior to the Closing Date.

     10.  Effective Date of Agreement. This Agreement shall become effective:
          ---------------------------
(i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at
the time this Agreement is executed and delivered, it is necessary for the
Registration Statement or a post-effective amendment thereto to be declared
effective before the offering of the Shares may commence, when notification of
the effectiveness of the Registration Statement or such post-effective amendment
has been released by the Commission. Until such time as this Agreement shall
have

                                       29

<PAGE>

become effective, it may be terminated by the Fund by notifying you or by you,
as Representatives of the several Underwriters, by notifying the Fund.

          If any one or more of the Underwriters shall fail or refuse to
purchase Firm Shares which it or they have agreed to purchase hereunder and the
aggregate number of Firm Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase is not more than one-tenth
of the aggregate number of the Firm Shares, each non-defaulting Underwriter
shall be obligated, severally, in the proportion which the aggregate number of
Firm Shares set forth opposite its name in Schedule I hereto bears to the
aggregate number of Firm Shares set forth opposite the names of all
non-defaulting Underwriters or in such other proportion as you may specify in
accordance with Section 20 of the Salomon Smith Barney Master Agreement Among
Underwriters, to purchase Firm Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase. If any Underwriter or
Underwriters shall fail or refuse to purchase Firm Shares and the aggregate
number of Firm Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Firm Shares and arrangements satisfactory
to you and the Fund for the purchase of such Firm Shares by one or more
non-defaulting Underwriters or other party or parties approved by you and the
Fund are not made within 36 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Underwriter or the
Fund. In any such case which does not result in termination of this Agreement,
either you or the Fund 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 the Prospectus or 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 such default
of any such Underwriter under this Agreement. The term "Underwriter" as used in
this Agreement includes, for all purposes of this Agreement, any party not
listed in Schedule I hereto who, with your approval and the approval of the
Fund, purchases Firm Shares which a defaulting Underwriter agreed, but failed or
refused, to purchase.

     Any notice under this Section 10 may be made by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

     11.  Termination of Agreement. This Agreement shall be subject to
          ------------------------
termination in your absolute discretion, without liability on the part of any
Underwriter to the Fund or the Manager by notice to the Fund or the Manager if
prior to the Closing Date or any Option Closing Date (if different from the
Closing Date and then only as to the Additional Shares), as the case may be, (i)
trading in the Shares or securities generally on the NYSE, AMEX, Nasdaq National
Market or the Nasdaq Stock Market shall have been suspended or materially
limited, (ii) additional material governmental restrictions not in force on the
date of this Agreement have been imposed upon trading in securities generally or
a general moratorium on commercial banking activities in New York shall have
been declared by either Federal or state authorities or (iii) any outbreak or
material escalation of hostilities or other international or domestic calamity,
crisis or change in political, financial or economic conditions, occurs, the
effect of which is such as to make it, in your judgment, impracticable or
inadvisable to commence or continue the offering of the Shares at the offering
price to the public set forth on the cover page of the Prospectus or to enforce

                                       30

<PAGE>

contracts for the resale of the Shares by the Underwriters. Notice of such
termination may be given to the Fund or the Manager by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

     12.  Expenses. The Fund agrees to pay the following costs and expenses and
          --------
all other costs and expenses incident to the performance by the Fund of its
obligations hereunder: (a) the preparation, printing or reproduction, filing

     Notwithstanding the foregoing, in the event that the sale of the Firm
Shares is not consummated pursuant to Section 2 hereof, the Manager will pay the
costs and expenses of the Fund set forth above in this Section 12 (a) through
