Dear Sirs:

         The undersigned, Nuveen Insured Massachusetts Tax-Free 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".

         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 _______, 2002, a master custodian agreement with State Street Bank
and Trust Company dated _______, 2002 and a transfer agency and service
agreement with State Street Bank and Trust Company dated _______, 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 Nos. 333-100352 and
811-21216) 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 (a "462(b) Registration Statement") (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 at the time it became
effective 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. For the
avoidance of doubt, if the Fund has filed a 462(b) Registration Statement, the
term "Registration Statement" as used in this Agreement shall include such
462(b) Registration Statement. 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 statement of additional
information) subject to completion in the form included in the registration

                                       2



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

jointly and severally, agree with the several Underwriters as follows:

     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

     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 is first 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 of 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), 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 hereinafter 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 hereinafter 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

                                       5



     Regulations 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 or of the
     necessity to amend or supplement the Registration Statement, the
     Prospectus, any Prepricing Prospectus or any sales material (as hereinafter
     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,

                                       6



     prior to the date of the Prospectus, of each Prepricing Prospectus so
     furnished by the Fund.

               (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.

                                       7



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

               (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.

                                       8



          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:

               (a) Each Prepricing Prospectus included as part of the
         registration statement as originally filed or as part of any amendment
         or supplement thereto 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
         becomes effective and also in such form as it may be when any
         post-effective amendment thereto shall become effective and the
         Prospectus and any amendment or supplement thereto when filed with the
         Commission under Rule 497 of the 1933 Act Rules and Regulations and the

         and sale of the Shares other than the Registration Statement, the
         Prepricing Prospectus included in Pre-Effective Amendment No. 1 to the
         Registration Statement, the Prospectus and the advertisements/sales
         literature filed by Nuveen Investments with the NASD on _______, 2002.

               (o) The Fund has such licenses, permits, and authorizations of
         governmental or regulatory authorities ("permits") as are necessary to
         own its property and to conduct its business in the manner described in
         the Prospectus (and any amendment or supplement thereto); the Fund has
         fulfilled and performed all its material obligations with respect to
         such permits and no event has occurred which allows or, after notice or
         lapse of time, would allow, revocation or termination thereof or
         results in any other material impairment of the rights of the Fund
         under any such permit, subject in each case to such qualification as
         may be set forth in the Prospectus (and any amendment or supplement
         thereto); and, except as described in the Prospectus (and any amendment
         or supplement thereto), none of such permits contains any restriction
         that is materially burdensome to the Fund.

               (p) The Fund maintains and will maintain a system of internal
         accounting controls sufficient to provide reasonable assurances that

         or specific authorization and with the investment policies and
         restrictions of the Fund and the applicable requirements of the 1940
         Act, the 1940 Act Rules and Regulations and the Internal Revenue Code
         of 1986, as amended (the "Code"); (ii) transactions are recorded as
         necessary to permit preparation of financial statements in conformity
         with generally accepted accounting principles, to calculate net asset
         value, to maintain accountability for assets and to maintain material
         compliance with the books and records requirements under the 1940 Act
         and the 1940 Act Rules and Regulations; (iii) access to assets is
         permitted only in accordance with management's general or specific
         authorization; and (iv) the recorded account for assets is compared
         with existing assets at reasonable intervals and appropriate action is
         taken with respect to any differences.

               (q) The conduct by the Fund of its business (as described in the
         Prospectus) does not require it to be the owner, possessor or licensee
         of any patents, patent licenses, trademarks, service marks or trade
         names which it does not own, possess or license.

               (r) Except as stated in this Agreement and in the Prospectus (and
         any amendment or supplement thereto), the Fund has not taken and will
         not take, directly or indirectly, any action designed to or which
         should reasonably be expected to cause or result in or which will
         constitute stabilization or manipulation of the price of the Common
         Shares in violation of federal securities laws and the Fund is not
         aware of any such action taken or to be taken by any affiliates of the
         Fund.

                                       12

               (k) Except as stated in this Agreement and in the Prospectus (and
         in any amendment or supplement thereto), the Manager has not taken and
         will not take, directly or indirectly, any action designed to or which
         should reasonably be expected to cause or result in or which will
         constitute, stabilization or manipulation of the price of the Common
         Shares in violation of federal securities laws and the Manager is not
         aware of any such action taken or to be taken by any affiliates of the
         Manager.

               (l) In the event that the Fund or the Manager makes available any
         promotional materials intended for use only by qualified broker-dealers
         and registered representatives thereof by means of an Internet web site
         or similar electronic means, the Manager will install and maintain
         pre-qualification and password-protection or similar procedures which
         are reasonably designed to effectively prohibit access to such
         promotional materials by persons other than qualified broker-dealers
         and registered representatives thereof.

     8. Indemnification and Contribution.

               (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.

                                       16



               (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, the
         Prospectus or any Prepricing Prospectus (or any amendment

                                       17



         or supplement to any of the foregoing). 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 Registration Statement, the Prospectus or any
         Prepricing Prospectus (or any amendment or supplement to any of the
         foregoing) 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 and the Manager 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

                                       18



         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 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

                                       19



amendment or supplement thereto), the Closing Date and, with respect to any
Additional Shares, any Option Closing Date; to the accuracy and completeness of
all statements made by the Fund, 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



                    (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 this Agreement and the Fund
               Agreements by such other parties 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



               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



                    (xiii) The Fund is duly registered with the Commission under
               the 1940 Act as a closed-end, non-diversified 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



                    (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 State of Illinois,
         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
         McCutchen LLP and Edwards & Angell LLP or, as to other matters, other
         counsel of good standing whom they believe to be reliable and who are
         satisfactory to the Representatives; provided that (X) such reliance is
         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, satisfactory to them and their counsel and (Y) Bell, Boyd &
         Lloyd LLC states in their opinion that they believe that they and the
         Underwriters are justified in relying thereon. As to matters involving
         the application of the federal laws of the United States to the Taxable
         Equivalent Yield Tables contained in Appendix B to the statement of
         additional information, such counsel may rely on the comfort letter
         provided by Chapman and Cutler. In addition, in giving the opinion
         contained in Section 9(b)(vii) above, such counsel may rely on the
         paragraphs in the opinion of Gifford R. Zimmerman corresponding to
         Sections 9(c)(i), (iii) and (v) below; provided that (x) such reliance
         is expressly authorized by the opinion so relied upon and (y) Bell,
         Boyd & Lloyd LLC states in its opinion that it believes that it and the
         Underwriters are justified in relying thereon.

               (c) You shall have received on the Closing Date an opinion of
         Gifford R. Zimmerman, Managing Director, Assistant Secretary and
         General Counsel for the

                                       24



         Manager, dated the Closing Date and addressed to you, as
         Representatives of the several Underwriters, to the effect that:

                    (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 properties and to conduct its business as
               described in the Registration Statement and the Prospectus (and
               any amendment or supplement to either of them) and is duly
               registered and qualified to conduct its business and is in good
               standing in each jurisdiction or place where the nature of its
               properties or the conduct of its business requires such
               registration or qualification, except where the failure to so
               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

                                       25



               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;

                    (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

                                       26



               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 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) (i) You shall have received on the Closing Date an opinion of
         Edwards & Angell LLP, special Commonwealth of Massachusetts counsel to
         the Fund, dated the Closing Date and addressed to you, as
         Representatives of the several Underwriters, to the effect that:

                    The statements contained in the Prospectus under the
               headings "Risks - Concentration Risk" and "Tax Matters -
               Massachusetts Tax Matters" and in Appendix D to the statement of
               additional information under the headings "Factors Pertaining to
               Massachusetts" and "Massachusetts Tax Matters", to the extent
               that such statements constitute matters of law or legal
               conclusions, provide a fair and accurate summary of such law or
               conclusions. Such statements are based on current law and special
               counsel's understanding of the Fund's proposed operations, as
               disclosed in the Prospectus.

               Such counsel shall also state that although special counsel does
         not pass upon or assume any responsibility for the accuracy,
         completeness or fairness of the statements contained in the
         Registration Statement or the Prospectus (other than to the extent set
         forth above), and has not made any independent check or verification
         thereof, no facts have come to the attention of such special counsel
         which would lead it to believe that the material contained under the
         headings "Risks - Concentration Risk" and "Tax Matters - Massachusetts
         Tax Matters" and in Appendix D to the statement of additional
         information under the headings "Factors Pertaining to Massachusetts"
         and "Massachusetts Tax Matters" in the Registration Statement, at the
         time the Registration Statement became effective, or in 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 the material contained under such headings in 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

                                       27



         statements therein, in light of the circumstances under which they were
         made, not misleading.

               In rendering such opinion, such special counsel may rely as to
         matters of fact, to the extent such special counsel deems proper, on
         certificates of responsible officers of the Fund and of the Manager,
         and of public officials.

                    (ii) 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".

         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

                                       28



         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.

               (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, dated such date, of the chief administrative officer,
         president, any managing director or any vice president and of the
         controller or treasurer of each of the Fund and the Manager certifying
         that (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 officers of the Manager) in this Agreement are true and
         correct on and as of the date of the certificate as if made on such
         date, (iii) since the date of the Prospectus (and any amendment or
         supplement thereto) there has not been any material, adverse change in
         the condition (financial or other), business, prospects (other than as
         a result of a change in the financial markets generally), properties,
         net assets or results of operations of the Fund (with respect to the
         certificates from such Fund officers) or the Manager (with respect to
         the certificates from such officers of the Manager), (iv) to the
         knowledge of such officers after reasonable investigation, no order
         suspending the effectiveness of the Registration Statement or
         prohibiting the sale of any of the Shares or having a material, adverse
         effect on the Fund (with respect to the certificates from such Fund
         officers) or the Manager

                                       29



         (with respect to the certificates from such officers of the Manager)
         has been issued and no proceedings for any such purpose are pending
         before or threatened by the Commission or any court or other regulatory
         body, 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, (v) each of the Fund (with respect to certificates from
         such Fund officers) and the Manager (with respect to certificates from
         such officers of the Manager) has performed and complied with all
         agreements that this Agreement requires it to perform by such Closing
         Date, (vi) neither the Fund (with respect to the certificate from such
         officers of the Fund) nor the Manager (with respect to the certificate
         from such officers of the Manager) has 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 (vii) with respect to the
         certificate from such officers of the Fund, there has not been any
         change in the capital stock of the Fund nor any material increase in
         the debt of the Fund from that set forth in the Prospectus (and any
         amendment or supplement thereto) and the Fund has not sustained any
         material liabilities or obligations, direct or contingent, other than
         those reflected in the Prospectus (and any amendment or supplement
         thereto).

               (k) That the Fund and the Manager shall have furnished to you
         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 in compliance with the provisions hereof only if they are
         satisfactory in form and substance to you and your counsel acting in
         good faith.

               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 Underwriters' counsel, shall be deemed a
         representation and warranty by the 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 representations and warranties of the Fund and the
         Manager contained herein on and as of the Option Closing Date as though
         made on any Option Closing Date, (ii) satisfaction on and as of any
         Option Closing Date of the conditions set forth in this Section 9
         except that, if any Option Closing Date is other than the Closing Date,
         the certificates, opinions and letters referred to in paragraphs (b),
         (c), (d), (e), (f), (j), (k) and this paragraph shall be dated the
         Option Closing Date in question and the opinions and letters called for
         by paragraphs (b), (c), (d) and (e) shall be revised to reflect the
         sale of Additional Shares and (iii) the absence of circumstances on or
         prior to the Option Closing Date which would permit termination of this
         Agreement pursuant to Section 11 hereof if they existed on or prior to
         the Closing Date.

                                       30



     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 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 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 the
Underwriters to the Fund or the Manager, by notice given to the Fund or the
Manager prior to delivery of and payment for the Firm Shares and any Additional
Shares, as the case may be, if at any time prior to such time (i) trading in the
Fund's Common Shares shall have been suspended by the Commission or the AMEX or
trading in securities generally on the NYSE or the AMEX shall have been
suspended or limited or minimum prices for trading in securities generally shall
have been established on either of such Exchanges, (ii) a commercial banking
moratorium shall have been declared by either federal or

                                       31



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 in the United States is such as to make it, in your sole judgment,
impracticable or inadvisable to proceed with the offering or delivery of the
Shares as contemplated by the Prospectus (exclusive of any supplement thereto).
Notice of such termination may be given to the Fund or the Manager by telegram,
telecopy or telephone and 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
(including, without limitation, the filing fees prescribed by the 1933 Act, the

Statement (including exhibits thereto), the Prospectus, each Prepricing
Prospectus and the 1940 Act Notification and all amendments or supplements to
any of them, (b) the printing (or reproduction) and delivery (including postage,
air freight charges and charges for counting and packaging) of such copies of

Shares, (c) the preparation, printing, authentication, issuance and delivery of
certificates for the Shares, including any stamp taxes and transfer agent and
registrar fees payable in connection with the original issuance and sale of such
Shares, (d) the registrations or qualifications of the Shares for offer and sale

and such registration and qualification), (e) the fees and expenses of the
Fund's independent accountants, counsel for the Fund and of the transfer agent,
(f) the expenses of delivery to the Underwriters and dealers (including postage,

the Prepricing Prospectus, any sales material and all amendments or supplements
to the Prospectus as may be requested for use in connection with the offering
and sale of the Shares, (g) the printing (or reproduction) and delivery of this
Agreement, any dealer agreements, the preliminary and supplemental Blue Sky
Memoranda and all other company-authorized agreements or other documents printed

connection with any filings required to be made with the NASD and incurred with
respect to the review of the offering of the Shares by the NASD and (i) the

the AMEX.

     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

shall be made in accordance with Section 5(k) hereof.
