                         INVESTMENT MANAGEMENT AGREEMENT

AGREEMENT made as of the 1st day of February, l999, by and between NUVEEN MONEY
MARKET TRUST, a Massachusetts business trust (the "Trust"), and NUVEEN ADVISORY
CORP., a Delaware corporation (the "Adviser").

                                   WITNESSETH

In consideration of the mutual covenants hereinafter contained, it is hereby
agreed by and between the parties hereto as follows:

1. The Trust hereby employs the Adviser to act as the investment adviser for,
and to manage the investment and reinvestment of the assets of each of the
Trust's series as set forth on Exhibit A attached hereto (the "Funds") or as may
exist from time to time in accordance with the Trust's investment objective and
policies and limitations relating to such Fund, and to administer the Trust's
affairs to the extent requested by and subject to the supervision of the Board
of Trustees of the Trust for the period and upon the terms herein set forth. The
investment of the assets of each Fund shall be subject to the Trust's policies,
restrictions and limitations with respect to securities investments as set forth
in the Trust's registration statement on Form N-1A under the Securities Act of
1933 and the Investment Company Act of l940 covering the Trust's Funds' shares
of beneficial interest, including the Prospectus and Statement of Additional
Information forming a part thereof, all as filed with the Securities and
Exchange Commission and as from time to time amended, and

all applicable laws and the regulations of the Securities and Exchange
Commission relating to the management of registered open-end, management
investment companies.

The Adviser accepts such employment and agrees during such period to render such
services, to furnish office facilities and equipment and clerical, bookkeeping
and administrative services (other than such services, if any, provided by the
Trust's custodian, transfer agent and shareholder service agent, and the like)
for the Trust, to permit any of its officers or employees to serve without
compensation as trustees or officers of the Trust if elected to such positions,
and to assume the obligations herein set forth for the compensation herein
provided. The Adviser shall, for all purposes herein provided, be deemed to be
an independent contractor and, unless otherwise expressly provided or
authorized, shall have no authority to act for nor represent the Trust in any
way, nor otherwise be deemed an agent of the Trust.

2. For the services and facilities described in Section l, the Trust will pay to
the Adviser, at the end of each calendar month, an investment management fee
related to each of the Trust's Funds. For each Fund, calculated separately,
except the Nuveen Municipal Money Market Fund and Nuveen Money Market Fund, the
fees shall be computed at the rate of:

                                                                               2

                     RATE                     NET ASSETS
                     ----                     ----------
                    .4500%           For the first $125 million
                    .4375%           For the next $125 million

                    .4125%           For the next $500 million
                    .4000%           For the next $1 billion
                    .3750%           For assets over $2 billion

For Nuveen Municipal Money Market Fund, the fees shall be computed at the rate
of:
                     RATE                     NET ASSETS
                     ----                     ----------
                    .5000%           For the first $125 million
                    .4875%           For the next $125 million

                    .4500%           For the next $1 billion
                    .4250%           For assets over $2 billion

For the month and year in which this Agreement becomes effective or terminates,
and for any month and year in which a Fund is added or eliminated from the
Trust, there shall be an appropriate proration on the basis of the number of
days that the Agreement shall have been in effect, or the Fund shall have
existed, during the month and year, respectively. The services of the Adviser to
the Trust under this Agreement are not to be deemed exclusive, and the Adviser
shall be free to render similar services or other services to others so long as
its services hereunder are not impaired thereby.

3. The net asset value of each Fund shall be calculated as provided in the
Declaration of Trust of the Trust. On each day when net asset value is not
calculated, the net asset value of a share of beneficial interest of a Fund
shall be deemed to be the net asset value of such share as of the close of

                                                                               3

business on the last day on which such calculation was made for the purpose of
the foregoing computations.

4. Regardless of any of the above provisions, the Adviser guarantees that the
total expenses of each Fund in any fiscal year, exclusive of taxes, interest,
brokerage commissions, and extraordinary expenses such as litigation costs,
shall not exceed, and the Adviser undertakes to pay or refund to the Fund any
amount up to but not greater than the aggregate fees received by the Adviser
under this Agreement for such fiscal year, the limitation imposed by any
jurisdiction in which the Trust continues to offer and sell shares of the Fund
after exceeding such limitation. Except as otherwise agreed to by the Trust or
the Adviser or unless otherwise required by the law or regulation of any state,
any reimbursement by the Adviser to a Fund under this section shall not exceed
the management fee payable to the Adviser by a Fund under this Agreement.

5. The Adviser shall arrange for officers or employees of the Adviser to serve,
without compensation from the Trust, as trustees, officers or agents of the
Trust, if duly elected or appointed to such positions, and subject to their
individual consent and to any limitations imposed by law.

6. Subject to applicable statutes and regulations, it is understood that
officers, trustees, or agents of the Trust are, or may be, interested in the
Adviser as officers, directors, agents, shareholders or otherwise, and that the
officers, directors, shareholders and agents of the Adviser may be interested in
the Trust otherwise than as trustees, officers or agents.

                                                                               5

7. The Adviser shall not be liable for any loss sustained by reason of the
purchase, sale or retention of any security, whether or not such purchase, sale
or retention shall have been based upon the investigation and research made by
any other individual, firm or corporation, if such recommendation shall have
been selected with due care and in good faith, except loss resulting from
willful misfeasance, bad faith, or gross negligence on the part of the Adviser
in the performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties under this Agreement.

8. The Adviser currently manages other investment accounts and Trusts, including
those with investment objectives similar to the Trust, and reserves the right to
manage other such accounts and funds in the future. Securities considered as
investments for a Fund of the Trust may also be appropriate for other Funds or
for other investment accounts and funds that may be managed by the Adviser.
Subject to applicable laws and regulations, the Adviser will attempt to allocate
equitably portfolio transactions among the Trust's Funds and the portfolios of
its other investment accounts and funds purchasing securities whenever decisions
are made to purchase or sell securities by a Fund and another fund's portfolio
or one or more of such other accounts or funds simultaneously. In making such
allocations, the main factors to be considered by the Adviser will be the
respective investment objectives of the Trust's Fund or Funds purchasing such
securities and such other accounts and funds, the relative size of portfolio
holdings of the same or comparable securities, the availability of cash for
investment by the Trust's Funds and such other accounts and funds, the size of
investment commitments generally held by the Trust's Funds and such accounts and
funds, and

                                                                               6

the opinions of the persons responsible for recommending investments to the
Trust and such other accounts and funds.

9. This Agreement shall continue in effect until August 1, 2000, unless and
until terminated by either party as hereinafter provided, and shall continue in
force from year to year thereafter, but only as long as such continuance is
specifically approved, at least annually, in the manner required by the
Investment Company Act of l940.

This Agreement shall automatically terminate in the event of its assignment, and
may be terminated at any time without the payment of any penalty by the Trust or
by the Adviser upon sixty (60) days' written notice to the other party. The
Trust may effect termination by action of the Board of Trustees, or, with
respect to any Trust Fund, by vote of a majority of the outstanding voting
securities of that Fund, accompanied by appropriate notice.

This Agreement may be terminated, at any time, without the payment of any
penalty, by the Board of Trustees of the Trust, or, with respect to any Trust
Fund, by vote of a majority of the outstanding voting securities of that Fund,
in the event that it shall have been established by a court of competent
jurisdiction that the Adviser, or any officer or director of the Adviser, has
taken any action which results in a breach of the covenants of the Adviser set
forth herein.

Termination of this Agreement shall not affect the right of the Adviser to
receive payments on any unpaid balance of the compensation, described in Section
2, earned prior to such termination.

                                                                               6

10. If any provision of this Agreement shall be held or made invalid by a court
decision, statute, rule, or otherwise, the remainder shall not be thereby
affected.

11. The Adviser and its affiliates reserve the right to grant, at any time, the
use of the name "Nuveen", or any approximation or abbreviation thereof, to any
other investment company or business enterprise. Upon termination of this
Agreement by either party, or by its terms, the Trust shall thereafter refrain
from using any name of the Trust which includes "Nuveen" or any approximation or
abbreviation thereof, or is sufficiently similar to such name as to be likely to
cause confusion with such name, and shall not allude in any public statement or
advertisement to the former association.

12. Any notice under this Agreement shall be in writing, addressed and delivered
or mailed, postage prepaid, to the other party at such address as such other
party may designate for receipt of such notice.

                                                                               7

13. The Trust's Declaration of Trust is on file with the Secretary of the
Commonwealth of Massachusetts. This Agreement is executed on behalf of the Trust
by the Trust's officers as officers and not individually and the obligations
imposed upon the Trust by this Agreement are not binding upon any of the Trust's
Trustees, officers or shareholders individually but are binding only upon the
assets and property of the Trust.

         IN WITNESS WHEREOF, the Trust and the Adviser have caused this
Agreement to be executed on the day and year above written.

                  to effect the payment of dividends and distributions and to

                            (n) make such reports and recommendations to the

                  Except as otherwise instructed from time to time by the
         Trustees, with respect to execution of transactions for the Fund,
         Manager shall place, or arrange for the placement of, all orders for
         purchases, sales, or loans with issuers, brokers, dealers or other
         counterparts or agents selected by Manager. In connection with the
         selection of all such parties for the placement of all such orders,
         Manager shall attempt to obtain most favorable execution and price, but
         may nevertheless in its sole discretion as a secondary factor, purchase
         and sell portfolio securities from and to brokers and dealers who
         provide Manager with statistical, research and other information,
         analysis, advice, and similar services. In recognition of such services
         or brokerage services provided by a broker or dealer, Manager is hereby
         authorized to pay such broker or dealer a commission or spread in
         excess of that which might be charged by another broker or dealer for
         the same transaction if the Manager determines in good faith that the
         commission or spread is reasonable in relation to the value of the
         services so provided.

                  The Fund hereby authorizes any entity or person associated
         with Manager that is a member of a national securities exchange to
         effect any transaction on the exchange for the account of a Fund to the
         extent permitted by and in accordance with Section 11(a) of the
         Securities Exchange Act or 1934 and Rule 11a2-2(T) thereunder. The Fund
         hereby consents to the retention by such entity or person of
         compensation for such transactions in accordance with Rule
         11a-2-2(T)(a)(iv).

                  Manager may, where it deems to be advisable, aggregate orders
         for its other customers together with any securities of the same type
         to be sold or purchased for the Fund in order to obtain best execution
         or lower brokerage commissions. In such event, Manager shall allocate
         the shares so purchased or sold, as well as the expenses incurred in
         the transaction, in a manner it considers to be equitable and fair and
         consistent with its fiduciary obligations to the Fund and Manager's
         other customers.

                  Manager shall for all purposes be deemed to be an independent
         contractor and not an agent of the Fund and shall, unless otherwise
         expressly provided or authorized, have no authority to act for or
         represent the Fund in any way.

                  5. Allocation of Expenses Borne by the Fund. Any expenses
         borne by the Fund that are attributable solely to the organization,
         operation or business of the Fund shall be paid solely out of Fund
         assets. Any expense borne by the Fund which is not solely attributable
         to the Fund, shall be apportioned in such manner as Manager determines
         is fair and appropriate, or as otherwise specified by the Board of
         Trustees.

                  6. Expenses Borne by Manager. Manager at its own expense shall
         furnish all executive and other personnel, office space, and office
         facilities required to render the investment management and
         administrative services set forth in this Agreement.

                  In the event that Manager pays or assumes any expenses of the
         Fund not required to be paid or assumed by Manager under this
         Agreement, Manager shall not be obligated hereby to pay or assume the
         same or similar expense in the future; provided that nothing contained
         herein shall be deemed to relieve Manager of any obligation to the Fund
         under any separate agreement or arrangement between the parties.

                  7. Management Fee. For the services rendered, facilities
         provided, and charges assumed and paid by Manager hereunder, the Fund
         shall pay to Manager out of the assets of the Fund fees at the annual
         rate as set forth in Schedule A to this Agreement. The management fee
         shall accrue on each calendar day, and shall be payable monthly on the
         first business day of the next succeeding calendar month. The daily fee
         accrual shall be computed by multiplying the fraction of one divided by
         the number of days in the calendar year by the applicable annual rate
         of fee, and multiplying this product by the Managed Assets of the Fund,
         as of the close of business on the last preceding business day on which
         the Fund's net asset value was determined. For purposes of calculation
         of the management fee, the Fund's Managed Assets shall mean the daily
         gross asset value of the Fund, minus the sum of (i) the Fund's accrued
         and unpaid dividends on any outstanding preferred shares of beneficial
         interest of the Fund ("Preferred Shares") and (ii) accrued liabilities
         (other than the amount of any borrowings incurred, commercial paper or
         notes issued by the Fund and liquidation preference of any outstanding
         Preferred Shares), using the values determined in the manner
         established by the Trustees.

                  8. Non-Exclusivity. The services of Manager to the Fund
         hereunder are not to be deemed exclusive and Manager shall be free to
         render similar services to others.

                  9. Standard of Care. The Manager shall not be liable for any
         loss sustained by reason of the purchase, sale or retention of any
         security, whether or not such purchase, sale or retention shall have
         been based upon the investigation and research made by any other
         individual, firm or corporation, if such recommendation shall have been
         selected with due care and in good faith, except loss resulting from
         willful misfeasance, bad faith,

                                      -7-
<PAGE>   7

         or gross negligence on the part of the Manager in the performance of
         its obligations and duties, or by reason of its reckless disregard of
         its obligations and duties under this Agreement.

                  10. Amendment. This Agreement may not be amended as to the
         Fund without the affirmative votes (a) of a majority of the Board of
         Trustees, including a majority of those Trustees who are not
         "interested persons" of the Fund or of Manager, voting in person at a
         meeting called for the purpose of voting on such approval, and (b) of a
         "majority of the outstanding shares" of the Fund. The terms "interested
         persons" and "vote of a majority of the outstanding shares" shall be
         construed in accordance with their respective definitions in the 1940
         Act and, with respect to the latter term, in accordance with Rule 18f-2
         under the 1940 Act.

                  11. Effective Date and Termination. This Agreement shall
         become effective as of the effective date for the Fund specified in
         Schedule A hereto. This Agreement may be terminated at any time,
         without payment of any penalty, by the Board of Trustees of the Fund,
         or by a vote of a majority of the outstanding shares, upon at least
         sixty (60) days' written notice to Manager. This Agreement may be
         terminated by Manager at any time upon at least sixty (60) days'
         written notice to the Fund. This Agreement shall terminate
         automatically in the event of its "assignment" (as defined in the 1940
         Act). Unless terminated as hereinbefore provided, this Agreement shall
         continue in effect for an initial period of two (2) years from the
         effective date applicable to the Fund specified in Schedule A and
         thereafter from year to year only so long as such continuance is
         specifically approved with respect to the Fund at least annually (a) by
         a majority of those Trustees who are not interested persons of the Fund
         or of Manager, voting in person at a meeting called for the purpose of
         voting on such approval, and (b) by either the Board of Trustees of the
         Fund or by a "vote of a majority of the outstanding shares" of the
         Fund.

                  12. Ownership of Records; Interparty Reporting. All records
         required to be maintained and preserved by the Fund pursuant to the
         provisions of rules or regulations of the Securities and Exchange
         Commission under Section 31(a) of the 1940 Act or other applicable laws
         or regulations which are maintained and preserved by Manager on behalf
         of the Fund and any other records the parties mutually agree shall be
         maintained by Manager on behalf of the Fund are the property of the
         Fund and shall be surrendered by Manager promptly on request by the
         Fund; provided that Manager may at its own expense make and retain
         copies of any such records.

                                      -8-

                  The Fund shall furnish or otherwise make available to Manager
         such copies of the financial statements, proxy statements, reports, and
         other information relating to the business and affairs of the Fund as
         Manager may, at any time or from time to time, reasonably require in
         order to discharge its obligations under this Agreement.

                  Manager shall prepare and furnish to the Fund statistical data
         and other information in such form and at such intervals as the Fund
         may reasonably request.

                  13. Non-Liability of Trustees and Shareholders. Any obligation
         of the Fund hereunder shall be binding only upon the assets of the Fund
         and shall not be binding upon any Trustee, officer, employee, agent or
         Shareholder of the Fund. Neither the authorization of any action by the
         Trustees or Shareholders of the Fund nor the execution of this
         Agreement on behalf of the Fund shall impose any liability upon any
         Trustee or any Shareholder.

                  14. Use of Manager's Name. The Fund may use the name "Nuveen
         Floating Rate Fund" or any other name derived from the name "Nuveen"
         only for so long as this Agreement or any extension, renewal, or
         amendment hereof remains in effect, including any similar agreement
         with any organization which shall have succeeded to the business of
         Manager as investment adviser. At such time as this Agreement or any
         extension, renewal or amendment hereof, or such other similar agreement
         shall no longer be in effect, the Fund will cease to use any name
         derived from the name "Nuveen" or otherwise connected with Manager, or
         with any organization which shall have succeeded to Manager's business
         as investment adviser.

                  15. References and Headings. In this Agreement and in any such
         amendment, references to this Agreement and all expressions such as
         "herein," "hereof," and "hereunder'" shall be deemed to refer to this
         Agreement as amended or affected by any such amendments. Headings are
         placed herein for convenience of reference only and shall not be taken
         as a part hereof or control or affect the meaning, construction, or
         effect of this Agreement. This Agreement may be executed in any number
         of counterparts, each of which shall be deemed an original.

                            (n) make such reports and recommendations to the
                  Board as the Board reasonably requests or deems appropriate;

                            (o) provide shareholder services to holders or
                  potential holders of the Fund's securities including, but not
                  limited to, shareholder requests for information.

                  Except as otherwise instructed from time to time by the
         Trustees, with respect to execution of transactions for the Fund,
         Manager shall place, or arrange for the placement of, all orders for
         purchases, sales, or loans with issuers, brokers, dealers or other
         counterparts or agents selected by Manager. In connection with the
         selection of all such parties for the placement of all such orders,
         Manager shall attempt to obtain most favorable execution and price, but
         may nevertheless in its sole discretion as a secondary factor, purchase
         and sell portfolio securities from and to brokers and dealers who
         provide Manager with statistical, research and other information,
         analysis, advice, and similar services. In recognition of such services
         or brokerage services provided by a broker or dealer, Manager is hereby
         authorized to pay such broker or dealer a commission or spread in
         excess of that which might be charged by another broker or dealer for
         the same transaction if the Manager determines in good faith that the
         commission or spread is reasonable in relation to the value of the
         services so provided.

                  The Fund hereby authorizes any entity or person associated
         with Manager that is a member of a national securities exchange to
         effect any transaction on the exchange for the account of a Fund to the
         extent permitted by and in accordance with Section 11(a) of the
         Securities Exchange Act or 1934 and Rule 11a2-2(T) thereunder. The Fund
         hereby consents to the retention by such entity or person of
         compensation for such transactions in accordance with Rule
         11a-2-2(T)(a)(iv).

                  Manager may, where it deems to be advisable, aggregate orders
         for its other customers together with any securities of the same type
         to be sold or purchased for the Fund in order to obtain best execution
         or lower brokerage commissions. In such event, Manager shall allocate
         the shares so purchased or sold, as well as the expenses incurred in
         the transaction, in a manner it considers to be equitable and fair and
         consistent with its fiduciary obligations to the Fund and Manager's
         other customers.

                  Manager shall for all purposes be deemed to be an independent
         contractor and not an agent of the Fund and shall, unless otherwise
         expressly provided or authorized, have no authority to act for or
         represent the Fund in any way.

                    2. Administrative Services. Subject to the terms of this
         Agreement and to the supervision and control of the Trustees, Manager
         shall provide to the Fund facilities, equipment, statistical and
         research data, clerical, accounting and bookkeeping services,

                                      -3-

         internal auditing and legal services, and personnel to carry out all
         management services required for operation of the business and affairs
         of the Fund other than those services to be performed by the Fund's
         Underwriter pursuant to an Underwriting Agreement, those services to be
         performed by the Fund's Custodian pursuant to a Custody Agreement,
         those services to be performed by the Fund's Transfer Agent pursuant to
         a Transfer Agency Agreement, those services to be provided pursuant to
         a Fund Accounting Agreement and those services normally performed by
         the Fund's counsel and auditors.

                    3. Use of Affiliated Companies and Subcontractors. In
         connection with the services to be provided by Manager under this
         Agreement, Manager may, to the extent it deems appropriate, and subject
         to compliance with the requirements of applicable laws and regulations,
         make use of (i) its affiliated companies and their directors, trustees,
         officers, and employees and (ii) subcontractors selected by Manager,
         provided that Manager shall supervise and remain fully responsible for
         the services of all such third parties in accordance with and to the
         extent provided by this Agreement. All costs and expenses associated
         with services provided by any such third parties shall be borne by
         Manager or such parties.

                    4. Expenses Borne by the Fund. Except to the extent
         expressly assumed by Manager herein or under a separate agreement
         between the Fund and Manager and except to the extent required by law
         to be paid by Manager, Manager shall not be obligated to pay any costs
         or expenses incidental to the organization, operations or business of
         the Fund. Without limitation, costs and expenses for which the Manager
         shall have no obligation shall include but not be limited to:

<PAGE>   16
                    5. Allocation of Expenses Borne by the Fund. Any expenses
         borne by the Fund that are attributable solely to the organization,
         operation or business of the Fund shall be paid solely out of Fund
         assets. Any expense borne by the Fund which is not solely attributable
         to the Fund, shall be apportioned in such manner as Manager determines
         is fair and appropriate, or as otherwise specified by the Board of
         Trustees.

                    6. Expenses Borne by Manager. Manager at its own expense
         shall furnish all executive and other personnel, office space, and
         office facilities required to render the investment management and
         administrative services set forth in this Agreement.

                  In the event that Manager pays or assumes any expenses of the
         Fund not required to be paid or assumed by Manager under this
         Agreement, Manager shall not be obligated hereby to pay or assume the
         same or similar expense in the future; provided that nothing contained
         herein shall be deemed to relieve Manager of any obligation to the Fund
         under any separate agreement or arrangement between the parties.

                    7. Management Fee. For the services rendered, facilities
         provided, and charges assumed and paid by Manager hereunder, the Fund
         shall pay to Manager out of the assets of the Fund fees at the annual
         rate as set forth in Schedule A to this Agreement. The management fee
         shall accrue on each calendar day, and shall be payable monthly on the
         first business day of the next succeeding calendar month. The daily fee
         accrual shall be computed by multiplying the fraction of one divided by
         the number of days in the calendar year by the applicable annual rate
         of fee, and multiplying this product by the Managed Assets of the Fund,
         as of the close of business on the last preceding business day on which
         the Fund's net asset value was determined. For purposes of calculation
         of the management fee, the Fund's Managed Assets shall mean the daily
         gross asset value of the Fund, minus the sum of (i) the Fund's accrued
         and unpaid dividends on any outstanding preferred shares of beneficial
         interest of the Fund ("Preferred Shares") and (ii) accrued liabilities
         (other than the amount of any borrowings incurred, commercial paper or
         notes issued by the Fund and liquidation preference of any outstanding
         Preferred Shares), using the values determined in the manner
         established by the Trustees.

                    8. Non-Exclusivity. The services of Manager to the Fund
         hereunder are not to be deemed exclusive and Manager shall be free to
         render similar services to others.

                    9. Standard of Care. The Manager shall not be liable for any
         loss sustained by reason of the purchase, sale or retention of any
         security, whether or not such purchase, sale or retention shall have
         been based upon the investigation and research made by any other
         individual, firm or corporation, if such recommendation shall have been
         selected with due care and in good faith, except loss resulting from
         willful misfeasance, bad faith,

                                      -6-
<PAGE>   17

         or gross negligence on the part of the Manager in the performance of
         its obligations and duties, or by reason of its reckless disregard of
         its obligations and duties under this Agreement.

                   10. Amendment. This Agreement may not be amended as to the
         Fund without the affirmative votes (a) of a majority of the Board of
         Trustees, including a majority of those Trustees who are not
         "interested persons" of the Fund or of Manager, voting in person at a
         meeting called for the purpose of voting on such approval, and (b) of a
         "majority of the outstanding shares" of the Fund. The terms "interested
         persons" and "vote of a majority of the outstanding shares" shall be
         construed in accordance with their respective definitions in the 1940
         Act and, with respect to the latter term, in accordance with Rule 18f-2
         under the 1940 Act.

                   11. Effective Date and Termination. This Agreement shall
         become effective as of the effective date for the Fund specified in
         Schedule A hereto. This Agreement may be terminated at any time,
         without payment of any penalty, by the Board of Trustees of the Fund,
         or by a vote of a majority of the outstanding shares, upon at least
         sixty (60) days' written notice to Manager. This Agreement may be
         terminated by Manager at any time upon at least sixty (60) days'
         written notice to the Fund. This Agreement shall terminate
         automatically in the event of its "assignment" (as defined in the 1940
         Act). Unless terminated as hereinbefore provided, this Agreement shall
         continue in effect for an initial period of two (2) years from the
         effective date applicable to the Fund specified in Schedule A and
         thereafter from year to year only so long as such continuance is
         specifically approved with respect to the Fund at least annually (a) by
         a majority of those Trustees who are not interested persons of the Fund
         or of Manager, voting in person at a meeting called for the purpose of
         voting on such approval, and (b) by either the Board of Trustees of the
         Fund or by a "vote of a majority of the outstanding shares" of the
         Fund.

                   12. Ownership of Records; Interparty Reporting. All records
         required to be maintained and preserved by the Fund pursuant to the
         provisions of rules or regulations of the Securities and Exchange
         Commission under Section 31(a) of the 1940 Act or other applicable laws
         or regulations which are maintained and preserved by Manager on behalf
         of the Fund and any other records the parties mutually agree shall be
         maintained by Manager on behalf of the Fund are the property of the
         Fund and shall be surrendered by Manager promptly on request by the
         Fund; provided that Manager may at its own expense make and retain
         copies of any such records.

                                      -7-

                  The Fund shall furnish or otherwise make available to Manager
         such copies of the financial statements, proxy statements, reports, and
         other information relating to the business and affairs of the Fund as
         Manager may, at any time or from time to time, reasonably require in
         order to discharge its obligations under this Agreement.

                  Manager shall prepare and furnish to the Fund statistical data
         and other information in such form and at such intervals as the Fund
         may reasonably request.

                   13. Non-Liability of Trustees and Shareholders. Any
         obligation of the Fund hereunder shall be binding only upon the assets
         of the Fund and shall not be binding upon any Trustee, officer,
         employee, agent or Shareholder of the Fund. Neither the authorization
         of any action by the Trustees or Shareholders of the Fund nor the
         execution of this Agreement on behalf of the Fund shall impose any
         liability upon any Trustee or any Shareholder.

                   14. Use of Manager's Name. The Fund may use the name "Nuveen
         Floating Rate Fund" or any other name derived from the name "Nuveen"
         only for so long as this Agreement or any extension, renewal, or
         amendment hereof remains in effect, including any similar agreement
         with any organization which shall have succeeded to the business of
         Manager as investment adviser. At such time as this Agreement or any
         extension, renewal or amendment hereof, or such other similar agreement
         shall no longer be in effect, the Fund will cease to use any name
         derived from the name "Nuveen" or otherwise connected with Manager, or
         with any organization which shall have succeeded to Manager's business
         as investment adviser.

                   15. References and Headings. In this Agreement and in any
         such amendment, references to this Agreement and all expressions such
         as "herein," "hereof," and "hereunder'" shall be deemed to refer to
         this Agreement as amended or affected by any such amendments. Headings
         are placed herein for convenience of reference only and shall not be
         taken as a part hereof or control or affect the meaning, construction,
         or effect of this Agreement. This Agreement may be executed in any
         number of counterparts, each of which shall be deemed an original.
