                                   TO BE HELD

                                December 9, 2005
                                     8:30AM
                           Investors Management Group
                                    Suite 200

                                1415 28th Street
                           West Des Moines, Iowa 50266

Dear Participant:

        At a Board of Trustees meeting on October 26, 2005 the Board considered
and approved a new Advisor Agreement for the Iowa Public Agency Investment Trust
("IPAIT"). This action was taken as a result of the announcement that our
investment advisor, Investors Management Group, Ltd. ("IMG"), would be acquired
by West Bancorporation, Inc., a West Des Moines based bank holding company.
Under the laws applicable to investment advisors and us, a change of control of
IMG immediately terminates the current Advisor Agreement. To permit IMG to
continue to serve as IPAIT's investment advisor after the change of control, the
Board approved a new Advisor Agreement with IMG, take effective on the date of
the change of control. This "new" agreement is essentially identical in all
material respects to the current Advisor Agreement.

        No change to the service provided by IMG is anticipated. The IMG
investment staff, Jeff Lorenzen, Laurie Mardis and Kevin Croft are all
anticipated to continue to manage IPAIT's investments. The IMG administrative
staff led by Amy Mitchell will also continue to serve you. In the end, the
change will simply result in IMG being owned by an Iowa banking organization
which many of you may know and do business with.

        The approval of a new Advisor Agreement requires the approval of the
Participants to be effective. As a result we have called a meeting of
participants to consider and approve the new agreement. In consideration of
these matters and on behalf of our Board of Trustees we encourage you to execute
and return the proxy provided herein A Notice of the Meeting and a Proxy
Statement, which describes the proposal, information about the Trustees, and how
to vote is enclosed.


     Your vote is important. While you may attend the meeting in person and
vote, you may vote by proxy as described in the Proxy Statement. If you choose
to vote by proxy, an authorized official of each Participant is asked to sign,
date and return the accompanying proxy card in the enclosed postage-paid return
envelope. You may also fax it to us toll-free at 866-260-0246. Faxing or
returning your proxy card to us will not prevent you from otherwise voting in
person, but will assure that your vote will be counted if you are not in
attendance and will ensure that a quorum will be present at the meeting which
will avoid the additional expense of further proxy solicitation if a quorum is
not present.

     It is very important that your proxy be received promptly. We need to
receive your card or fax no later than December 7, 2005.

     The IPAIT Board of Trustees recommends that the Participants approve the
new Advisor Agreement.

                                               Sincerely,

Dated: November __, 2005                       /s/  Thomas Hanafan

                              --------------------

                               GENERAL INFORMATION

     We are providing you with this Proxy Statement in connection with the
solicitation of proxies by and on behalf of Iowa Public Agency Investment Trust,
an Iowa common law trust organized under Chapter 28E of the Iowa Code ("IPAIT"),
for use at the Special Meeting of Participants to be held at the Waconda Club,
3915 Fleur Drive, Des Moines, Iowa 50321 on December 9, 2005, at 8:30 am local
time, and at any and all postponements or adjournments thereof (the "Meeting").
This proxy statement, the accompanying form of proxy, and the Notice of Special
Meeting will be first mailed or given to Participants on or about November __,
2005.

     Because many of the authorized representatives of IPAIT's Participants may
be unable to attend the Meeting in person, the Board of Trustees is soliciting
proxies to give each Participant an opportunity to vote on all matters presented
at the Meeting. Authorized representatives of the Participants are urged to:

    (1) read this Proxy Statement carefully;

    (2) specify their choice in each matter by marking the appropriate box on
        the enclosed Proxy,

    (3) sign, date and return the Proxy by mail in the postage-paid, return
        envelope provided, or

    (4) fax the Proxy toll-free to fax number 866-260-0246.

     If the accompanying proxy is executed properly by an authorized official of
a Participant and returned, the Participants so voting will be deemed to have
voted their Units at the Meeting in accordance with the instructions given. The
Board of Trustees of IPAIT recommends a vote FOR all proposals. If no
instructions are given, the Participant's Units will be voted FOR the approval
of all proposals and any other business as may properly come before the Meeting.


IPAIT'S ANNUAL AND SEMI-ANNUAL REPORTS HAVE PREVIOUSLY BEEN DELIVERED TO
PARTICIPANTS OF IPAIT. SUCH REPORTS ARE AVAILABLE AT NO COST BY CALLING
TOLL-FREE AT 800-872-4024, VIEWING ONLINE AT WWW.IPAIT.ORG, OR WRITING TO IPAIT
IN CARE OF INVESTORS MANAGEMENT GROUP, LTD. AT 1415 28th STREET, CENTURY II
BUILDING, SUITE 200, WEST DES MOINES, IOWA 50266-1461.

     Your vote is important. Please take a moment now to sign, date and return
the accompanying proxy card in the enclosed postage-paid return envelope.
Returning your proxy card will not prevent you from voting in person, but will
assure that your vote will be counted if you are unable to attend the meeting,
and will avoid the additional expense of further proxy solicitation and will
ensure that a quorum is represented at the meeting.


                   QUESTION AND ANSWER SUMMARY: ABOUT THE VOTE

What is being voted on at the Meeting?

     As more fully described in this proxy statement, the Board of Trustees of
IPAIT is asking Participants to consider and vote on the following proposal:

     To approve a new Advisor Agreement with Investors Management Group, Ltd to
be effective upon the acquisition of the Investors Management Group, Ltd. by
West Bancorporation, Inc.

We may also transact any other business as may properly come before the Meeting
or any adjournment thereof.

Who can vote at the Meeting?

     The Board of Trustees has set November 9, 2005 as the record date for the
Meeting. Only Participants at the close of business on the record date which
have positive account balances in either the Diversified Portfolio and or the
Direct Government Obligation Portfolio (the "Portfolios") will be entitled to
receive notice of and to vote at the Meeting. Each Participant will be entitled
to one vote per unit of beneficial ownership ("Unit") held in both Portfolios on
each matter properly submitted for vote at the Meeting. Participants of each
Portfolio vote separately on this proposal.


What constitutes a quorum for the Meeting?

     Quorum for the Meeting is based on the number Units outstanding held by
Participants in each Portfolio that are represented in person or by proxy. To
have a quorum for a Portfolio we need a majority of the Units of each of the
Diversified Portfolio and the Direct Government Obligation Portfolio to be
present, in person or by proxy. Proxies received will be considered present at
the Meeting for purposes of establishing a quorum for the transaction of
business at the meeting. The vote with respect to each proposal will be
tabulated separately.

     If a quorum is not present at the Meeting, or if a quorum is present at the
Meeting, but sufficient votes to approve a proposal are not received, the
persons named as proxies may propose one or more adjournments of the Meeting to
permit further solicitation of proxies with respect to a proposal. In
determining whether to adjourn the Meeting, the following factors may be
considered: the percentage of votes cast, the percentage of negative votes cast,
the nature of any further solicitation and the information to be provided to
Unit holders with respect to the reasons for the solicitation. Any adjournment
will require the affirmative vote of a majority of Units of each Portfolio
represented in person or by proxy at the Meeting. In that case, the persons
named as proxies will vote all proxies required to be voted for a proposal, FOR
such an adjournment; provided, however, any proxies required to be voted against
a proposal will be voted AGAINST such adjournment.

How to vote?

     If an authorized representative of each Participant completes and properly
signs the accompanying proxy card and return it to us, it will be voted as they
direct, unless they later revoke the proxy. Unless instructions to the contrary
are marked, or if no instructions are specified, Participants represented by a
proxy will be voted FOR the proposal set forth on the proxy, and in the
discretion of the persons named as proxies on such other matters as may properly
come before the Meeting. If you do not complete a proxy card and return it to us
or vote at the meeting, you will be treated as if you voted AGAINST a proposal.
If you check the box labeled ABSTAIN on the proxy card and return it to us, you
will be treated as if you voted AGAINST a proposal.

     If you attend the Meeting, you may deliver your completed proxy card or
vote in person. You may either mail the proxy card to us in the envelope
provided or you fax the signed proxy card toll-free to us at 866-260-0246.

Can the vote be changed after return of the proxy card?

     Yes. Even after you have submitted your proxy, you may change your vote at
any time before the proxy is exercised by filing with our Secretary, at the
address indicated above, either a written notice of revocation, a duly executed
proxy bearing a later date, or if you vote in person at the Meeting. The powers
of the proxy holders will be suspended if you attend the Meeting in person and
so request. However, attendance at the Meeting will not by itself revoke a
previously granted proxy.


     Any written notice of revocation sent to us must include the Participant's
name and must be received prior to the Meeting to be effective.

What vote is required to approve the proposals?

     The approval of the new Advisor Agreement as to each Portfolio requires the
affirmative vote of a majority of the outstanding Units of such Portfolio.

     Abstentions are counted in tabulations of the votes cast on proposals
presented to participants. Therefore, for all matters presented at the Meeting,
abstentions will have the same effect as a vote against the proposals.

                   PROPOSAL TO APPROVE A NEW ADVISOR AGREEMENT

          Investors Management Group, Ltd. ("IMG"), Suite 200, Century II
Building, 1415 28th Street, West Des Moines, Iowa 50266 has been the investment
advisor for IPAIT since IPAIT's inception in 1987. IMG is a wholly owned
subsidiary of AMCORE Investment Group, N.A. ("AIG"), a national bank. AIG is a
wholly owned subsidiary of AMCORE Financial, Inc. ("AMCORE") which is a publicly
traded mutli-bank holding company. AIG and AMCORE are based in Rockford,
Illinois and are engaged in banking and related financial services businesses in
Illinois and Wisconsin. On October 21, 2005 AMCORE and AIG executed a Stock
Purchase Agreement with West Bancorporation, Inc. ("West Bancorp.") that, if
consummated, will result in IMG being acquired by and becoming a wholly owned
subsidiary of West Bancorp. (the "Transaction"). West Bancorp. is a publicly
traded one bank holding company that owns and operates West Bank, an Iowa state
charted bank that operates from offices in West Des Moines, Iowa and WB Capital
Management Inc,. d/b/a VMF Capital, a registered investment advisor. Closing of
the Transaction is to occur on or before December 31, 2005.

          Under the laws applicable to IMG and IPAIT, the acquisition of IMG by
West Bancorp. will result in the automatic termination of the current Advisor
Agreement between IPAIT and IMG ("Current Advisor Agreement"). Consequently, in
order for IMG to continue to serve as IPAIT's investment advisor, a "new"
Advisor Agreement (the "New Advisor Agreement"), effective upon the consummation
of the Transaction must be approved by the Board of Trustees and the
Participants. In the event that the Transaction does not occur, IMG will
continue to manage IPAIT's assets under the Current Advisor Agreement.

          At its Meeting on October 26, 2005, the IPAIT Board of Trustees were
provided information regarding the Transaction and West Bancorp.'s plans for IMG
after the Transaction is consummated. There is not anticipated to be any
material change to the investment management structure of IMG. Jeff Lorenzen,
IMG's Chief Investment Officer, President and Director, along with his portfolio
managers Laurie Mardis and Kevin Croft are expected to continue in these
positions and will be subject to employment agreements for at least a three year
period after the Transaction. In addition, IMG's Secretary, Treasurer, Director
and Operations Manager, Amy Mitchell, will also be subject to an employment
agreement and continue for a like period. Other investment analysts and
administrative staff are also expected to continue to be employed by IMG after
the transaction. Patricia Bonavia, a Director and Chief Executive Officer of IMG
will, however, resign. Subsequent to the Transaction it is expected that West
Bancorp. will appoint a Director to the IMG Board to replace Ms. Bonavia,
however, who may be appointed or when this may occur is presently undecided.


The Current Advisor Agreement

          The Current Advisor Agreement is attached to this Proxy Statement as
Appendix A. The following is a summary of the essential terms of the Current
Advisor Agreement. The New Advisor Agreement is identical except with respect to
its term. The term of the New Advisor Agreement commences on the date that the
Transaction is closed and ends on December 31, 2006. This Summary is qualified
in its entirety by reference to the Advisor Agreement.

Term: The Current Advisor Agreement is effective for the period January 1, 2004
through December 31, 2006, subject to annual approval of the Board of Trustees
as required by the 40 Act and the right of the Board of Trustees to terminate
the agreement at anytime on 60 days prior notice. The Current Advisor Agreement
terminates automatically in the event of its assignment. The Current Advisor
Agreement was last approved by Participants on August 24, 2004 and was last
approved by the Board of Trustees on August 26, 2005.

Duties: IMG continuously supervises IPAIT's investment program and determines
what investments shall be purchased or sold and places all orders for the
purchase and sale of investments. IMG also attends all meetings of the
Participants and Trustees and assists with or conducts workshops and other
informational meetings organized or sponsored by IPAIT. IMG furnishes
information to the Board of Trustees as they may require and evaluates
performance of the IPAIT's various other service providers. IMG directly
consults with Participants and provides advice to them regarding their cash
management needs. IMG is responsible for monitoring compliance with the
amortized cost method of valuing IPAIT's assets (Rule 2a-7) and also complying
with laws and regulations applicable to IPAIT. IMG also provides program support
and support services including the services of a representative that works
directly with participants and who provides annual and quarterly reports to the
Trustees regarding these activities as well as recommendations for other
services.

Compensation: IPAIT pays to IMG a monthly fee computed at an annual rate of .12%
of the average daily assets of the combined Direct Government Obligation
Portfolio and the Diversified Portfolio up to $150,000,000. If either the Direct
Government Obligation Portfolio or the Diversified Portfolio's average daily
assets are greater than $150,000,000 but less than $250,000,000 then as to that
Portfolio, the fee for the amount over $150,000,000 is .095%. For average assets
over $250,000,000, the fee is .0.07%.


Expenses: IMG pays various expenses from its fees in connection with its
services to IPAIT. These include printing and postage costs of the Information
Statement, proxy material and reports sent to Participants. In addition IMG pays
for administrative costs of IPAIT associated with its performance under the
agreement. IPAIT pays for all other costs and expenses including interest and
taxes, brokerage commissions, compensation, if any, of Trustees, legal audit and
accounting expenses, custodian charges, insurance, meeting expenses, other
operations expenses directly incurred by IPAIT and authorized by the Board of
Trustees and other non reoccurring expenses, including obligations to indemnify
the Trustees.

Indemnity and Limitations of Liability: IPAIT does not indemnify or hold
harmless IMG for any acts or liabilities. IMG indemnifies and holds harmless
IPAIT against damages, claims, liability, and costs, including attorney's fees,
proximately caused by IMG's negligent error or omission in the performance of
professional services within the responsibility of IMG or as to any breach of
duty or obligation assumed by or required of IMG under the agreement.

Insurance: IMG is required to purchase and maintain a variety of insurance
coverages with specified limits covering its operations, including insurance
coverage for workers compensation, general commercial liability, automobile
liability and banker's professional coverage.

For the fiscal years ending June 30, 2005 and 2004, IPAIT paid IMG $275,011.00
and $346,989.75, respectively, in fees under the current Advisor Agreement.

In addition to advisory fees paid to IMG under Current Advisor Agreement, IMG is
also paid fees under an Administrator Agreement for various services in
connection with operating IPAIT on a daily basis. The Administrator Agreement
was also approved by the Board of Trustees, but is not required to be approved
by the Participants under the 40 Act. As a result the Board of Trustees is not
submitting it to the Participants for approval.

The names and principal occupations of IMG principal executive officers and
directors are as follows:

Jeffrey D. Lorenzen - Director, President and Chief Investment Officer - IMG.
Mr. Lorenzen's principal occupation has been as a portfolio manager and in
various other investment related positions for IMG since 1992.

Amy Mitchell, Director - Vice President, Treasurer, Chief Financial and
Operations Officer - IMG. Ms. Mitchell's principal occupation has been as
operations manager for IMG since 1990.

Vera Lichtenberger - Chief Compliance Officer - IMG. Ms. Lichtenberger principal
occupation is an attorney and has served as Chief Compliance Officer for IMG
since June, 2004.

Patricia Bonavia - Director and Chief Executive Officer. Ms. Bonavia's principal
occupation is as President of AMCORE Investment Services a division of AMCORE
Investment Group, N.A. a national bank and parent of IMG.


Each such person's address, except for Patricia Bonavia is that of IMG. Patricia
Bonavia's address is _____________________________, Rockford, Illinois. As noted
above, all will continue to serve in these same capacities after the Transaction
is consummated, except Patricia Bonavia, who will resign on the date the
Transaction is consummated.

Jeffrey D. Lorenzen has been designated as Principal Executive Officer of IPAIT;
Amy Mitchell has been designated as Chief Financial Officer of IPAIT and Vera
Lichtenberger serves as IPAIT's Chief Compliance Officer.

The New Advisor Agreement

          The New Advisor Agreement is identical to the Current Advisor
Agreement, in all material respects except its term. Thus, the key terms,
including fees, of the New Advisor Agreement are set out in detail above, under
the heading "The Current Advisor Agreement." The initial term of the New Advisor
Agreement will reflect the date on which the Transaction is consummated
(currently anticipated to be on or about December 31, 2005) as it's new
effective date. Assuming that the New Advisor Agreement is approved by
Participants, the New Advisor Agreement will then continue in effect until
December 31, 2006. Thereafter, the New Advisor Agreement will continue in effect
for successive annual periods, provided its continuance is approved at least
annually by (1) a majority vote, cast in person at a meeting called for that
purpose of the IPAIT Trustees or (2) a vote of the holders of a majority of the
outstanding Units of IPAIT.

Board Considerations Relating to the New Advisor Agreement

          On October 26, 2005, the Board of Trustees held a meeting called for
the purpose of considering, among other things the New Advisor Agreement and,
after careful review, determined that approving the New Advisor Agreement was in
the best interests of the Participants. At the meeting, senior officers of IMG
and AMCORE discussed the Transaction and the need to approve the New Advisor
Agreement due to the change of control of IMG. Representatives of West Bancorp.
also were present and discussed their plans for IMG. The Board of Trustees
considered a wide range of information, including information of the type they
considered on in August, 2005 when they last determined to continue IPAIT's
Current Advisor Agreement. In determining that the New Advisor Agreement was in
the best interests of the Participants, the Board of Trustees considered all
factors deemed to be relevant to IPAIT, including, but not limited to:


o    the expectation that the operation of IMG and IPAIT's day-to-day
     management, including the portfolio managers, will remain unchanged for the
     foreseeable future;

o    IMG and its personnel (including particularly those personnel with
     responsibilities for providing services to IPAIT ), resources and
     investment process will remain unchanged;


o    IMG will have access to the resources and personnel of West Bancorp. and
     its other subsidiaries;

o    the financial viability of IMG will remain unchanged;

o    the terms of the New Advisor Agreement, including the fee, will be the same
     as those of the Current Advisor Agreement;

o    the nature, extent and quality of the services that IMG has been providing
     to IPAIT will remain unchanged;

o    the investment performance of IPAIT over various periods;

o    the advisory fee rate payable to IMG by IPAIT and by other client accounts
     managed by IMG;

o    the total expense ratio of IPAIT and of similar funds managed by other
     advisers;

o    compensation payable by IPAIT to IMG for other services;

o    the historical profitability of the Current Advisor Agreement to IMG and to
     AMCORE and the projected profitability of the New Advisor Agreement to West
     Bancorp.;

o    the extent to which economies of scale would be realized from the fee
     structure as IPAIT grows.

          The Board considered the level and depth of knowledge of IMG,
including the information described below under the heading "IMG." In evaluating
the quality of services provided by IMG, the Board took into account its
familiarity with IMG's management through board meetings, conversations and
reports.

          The Board compared the advisory fees and total expense ratio of IPAIT
with various comparative data that it had been provided previously in approving
IPAIT's Current Advisor Agreement. This data compared the advisory fee to be
paid under the Current Advisor Agreement and estimates of the other expenses to
be paid by IPAIT to advisory fees and other expenses paid by comparable funds.
The comparative data assisted the Board in assessing the fairness and
reasonableness of Advisory fee to be paid under the Current Advisor Agreement as
well as the total estimated expenses to be paid by IPAIT. The Board considered
IPAIT's recent performance results and noted that the Board reviews on a
quarterly basis information about IPAIT's performance results, portfolio
composition and investment strategies. The Board also considered the
administration fee paid to IMG under IPAIT's Administration Agreement. The Board
noted that IPAIT's advisory fee and total expenses were equal to or below the
median of advisory fees and total expenses paid by its peer group of funds. The
Board also took into consideration the financial condition, costs and
profitability of the Advisor and West Bancorp. and any indirect benefits derived
by IMG from IMG's relationship with IPAIT.


          In considering the approval of the New Advisor Agreement, the Board,
including the Disinterested Trustees, did not identify any single factor as
controlling. Based on the Board's evaluation of all factors that it deemed to be
relevant, the Board, concluded that IMG has demonstrated that it possesses the
capability and resources necessary to perform the duties required of it under
the New Advisor Agreement; the costs of services to be provided and profits to
be realized by IMG are reasonable in comparison to those of investment advisers
of comparable funds; and the proposed advisory fee is fair and reasonable, given
the nature, extent and quality of the services to be rendered by IMG. The Board
further determined that the change in control of IMG did not present any
material change in the type and quality of service it would provide to IPAIT
which to date the Board considered to be of superior quality. Noting that the
realization of economies of scale is reflected by including breakpoints in the
advisory fee schedule, the Board concluded that IPAIT's shareholders would
benefit from economies of scale as IPAIT grows.

          The Trustees also considered the provisions of Section 15(f) of the
1940 Act, which provides, in relevant part, that affiliated persons may receive
compensation if (1) for a period of three years after the Transaction at least
75 percent of the Trustees of IPAIT are independent of IMG and (2) an "unfair
burden" is not imposed on IPAIT as a result of the Transaction. IMG and AMCORE
have agreed to pay all costs associated with the 2005 Special Meeting of
Participants due to the Transaction. In addition, if the Transaction is
consummated, it is expected that 100% of the Fund's Trustees will continue to be
Disinterested Trustees as all Trustees are currently disinterested and based on
the IPAIT's composition requirements, it is unlikely that there will ever be an
interested Trustee.

          After carefully reviewing all of these factors, the Board, unanimously
approved the New Advisor Agreement and recommended that IPAIT's Participants
vote to approve the New Advisor Agreement.


                             ADDITIONAL INFORMATION

The Advisor

        The Advisor is an Iowa corporation organized in 1982 and has been
registered as an investment advisor under the Investment Advisers Act of 1940,
as amended since that time. The business address of IMG is 1415 28th Street,
Century II Building, Suite 200, West Des Moines, Iowa 50266-1461.

insurance companies and one open-end mutual fund - the Vintage Mutual Funds,

Brokerage Commissions

          IPAIT paid no brokerage commissions or future commissions on its
securities purchases during its last fiscal year and it is unlikely that it will
do so in the future given its investment policies. The Fund does not participate
and does not in the future intend to participate in soft dollar or directed
brokerage arrangements.

                             SOLICITATION OF PROXIES

     This solicitation is being made by mail on behalf of the Board of Trustees
of IPAIT, but may also be made without additional remuneration by officers or
employees of the Adviser by telephone, telegraph, facsimile transmission,
electronic mail or personal interview. The expense of the printing and mailing
of this Proxy Statement and the enclosed form of Proxy and Notice of Special
Meeting, and any additional material relating to the Meeting, which may be
furnished to Participants by the Board subsequent to the furnishing of this
Proxy Statement, has been or will be borne by the Administrator. To obtain the
necessary representation of Participants at the Meeting, supplementary
solicitations may be made by mail, electronic mail, telephone or interview by
officers of IPAIT or employees of the Adviser. It is anticipated that the cost
of any other supplementary solicitations, if any, will not be material.

                  PARTICIPANT PROPOSALS FOR NEXT ANNUAL MEETING

     Annual meetings of Participants are not required to be held unless they are
necessary under the 1940 Act. Therefore, although the Board of Trustees may
determine to hold a special meeting in 2006 IPAIT may not hold Participant
meetings on an annual basis. A Participant proposal intended to be presented at
any meeting hereafter called must be received at IPAIT's offices a reasonable
time before IPAIT begins to print and mail its proxy materials for that meeting,
in order to be considered for inclusion in IPAIT's proxy statement and form of
proxy relating to such meeting. If a Participant fails to submit the proposal by
such date, IPAIT will not be required to provide any information about the
nature of the proposal in its proxy statement, and the proposal will not be
considered at that next annual meeting of Participants.

        Proposals should be sent to Robert Haug, IPAIT, Secretary, at 1735 NE
70th Avenue, Ankeny, Iowa 50021. The submission by a Participant of a proposal
for inclusion in a proxy statement does not guarantee that it will be included.
Participant proposals are subject to certain regulations under the federal
securities laws.


                                  OTHER MATTERS

     The Board is not aware of any matters to come before the Meeting, other
than the proposals specified in the Notice of Special Meeting. However, if any
other matter requiring a vote of the Participants should arise at the Meeting,
it is the intention of the persons named in the accompanying Proxy to vote such
Proxy in accordance with their best judgment.

        10. Evaluate the performance of the Trust, the Administrator and the

response to inquiries from Trustees and in responding thereto the Advisor will
seek such information, as is appropriate, from the Custodian and from other
parties. The Advisor will not undertake extensive independent investigations in
order to respond to such inquiries and will therefore not be liable for losses
or claims incurred by the Trust arising as a result of problems investigated by
the Advisor.

        11. In conjunction with the Administrator, provide, upon the request of
a Participant of the Trust, individualized advice and consultation to such
Participant regarding such Participant's cash management program.

        12. Monitor daily and weekly valuations of each series and if the
amortized cost value deviates materially from the market value (more than .5%)

or reduce material dilution or other unfair results to Participants.

        B. COMPLIANCE. The Advisor shall act in conformity with the Declaration,
        the Bylaws and the Information Statement and with the instructions and

        not limited to, the Investment Company Act of 1940 and all rules and
        regulations promulgated thereunder.

        C. PLACEMENT OF ORDERS. The Advisor shall place all orders for the

        Investments. The Advisor is authorized as the agent of the Trust to give
        oral instructions to the Trust's Administrator and Custodian, confirmed
        by written instructions to the Custodian, as to deliveries of securities
        and payments for the account of the Trust. In connection with the
        selection of brokers and dealers and the placing of orders, the Advisor
        is directed to seek the most favorable execution and price.


        D. BEST JUDGMENT. The Advisor shall give the Trust the benefit of its
        best judgment, experience and effort in rendering services hereunder,
        but the Advisor shall not be liable for any loss sustained by reason of
        the adoption of any investment policy or the purchase, sale or retention
        of any investment instrument, whether the purchase, sale or retention is
        based upon its own investigation and research or upon investigation and
        research made by any other individual, firm or corporation, if the
        purchase, sale or retention is made and such other individual, firm or
        corporation was selected with due care and in good faith. Nothing herein
        contained shall, however, be construed to protect the Advisor against
        any liability to the Trust or its Participants by reason of misfeasance,
        bad faith or negligence in the performance of its duties, or by reason
        of its reckless disregard of its obligations and duties under this
        Agreement, nor shall anything herein contained constitute a waiver or
        limitation on any rights which the Trust may have under any federal
        securities laws.

        E. MAINTAIN NAME OF TRUST. The Advisor will maintain the name "Iowa
        Public Agency Investment Trust" and assigns all right, title and
        interest in this name to the Trust and agrees to relinquish any and all
        right to use of this name by assignment or otherwise upon the
        termination of this Agreement or extension thereof.

illustrate the advantages of the investment services provided by the Trust to

compensation a fee as provided in attachment Exhibit A.

investment advisor or manager or administrator for any other person, firm,
corporation or entity and shall not in any way limit or restrict the Advisor or
any of its directors, officers, partners or employees, or any of its affiliates'
directors, officers, partners or employees from buying, selling or trading any
investment instruments for its or their own accounts, or for the accounts of
others for whom it or they may be acting. The Advisor represents that it will
undertake no activities which, in its judgment, will materially adversely affect
the performance of its obligations to the Trust under this Agreement. Directors,
officers, partners, employees and agents of the Advisor or of affiliated persons
of the Advisor may serve as officers, employees or agents of the Trust solely
within the limitations of the Declaration.

        Section 8.2. Compliance with Laws, Rules and Regulations. Anything in
this Agreement to the contrary notwithstanding, the Advisor shall refrain from
any action which, in its reasonable judgment, or in the judgment of the Trustees
of which the Advisor has written notice, would violate any law, rule or
regulation of any governmental body or agency having jurisdiction over the Trust
or its Participants or which would not be permitted by the Declaration.

        Section 8.3. Opinions and Reports. The Advisor shall provide such
opinions and reports of legal counsel and certified public accountants as may be

the adequacy and sufficiency of accounting, record keeping, and reporting
obligations of the Advisor pursuant to this Agreement.


        The Advisor shall provide the Trust with the most recent report of
independent auditors concerning its function pursuant to this Agreement. The
report shall be provided prior to each annual closing of the Trust; provided,
however, that the Advisor shall notify the Trust immediately upon receipt of any
such report which contains any qualifications or indication of existence of
weakness.

        The Advisor shall provide the trust within thirty (30) days of receipt
of all communications from its auditor or any regulatory authority of a material
weakness in internal control structure, or regulatory orders or sanctions
against the Advisor.

        Section 8.4. Recommendations. Without limiting the generality of the
foregoing paragraph, the Advisor shall not recommend, or arrange for, the
purchase by the Trust of any investment instrument which is not a Permitted
Investment or the purchase or other acquisition of which would constitute a
violation of the investment restrictions applicable to the Trust set forth in
the Declaration or the policies and procedures of the Trust of which it has
notice.

        Section 8.5. Dealing with Third Parties. When dealing with third parties
on behalf of the Trust in connection with the execution of investment
transactions and other matters, the Advisor shall include such recitals in
written documents as may be reasonably requested by the Trust pursuant to the
provisions of the Declaration regarding the limitation of liability of the
Trustees, Participants, officers, employees and agents of the Trust to third
parties.

instrument in writing executed by each party, or by their respective successors
or permitted assigns.

convenience of reference only and shall in no way define or limit any of the
provisions hereof or otherwise affect their construction or effect.

held invalid under any applicable statute or regulation or by a decision of a
court of competent jurisdiction, this invalidity shall not affect any other
provision of this Agreement that can be given effect without the invalid
provision, and, to this end, the provisions are severable.

        Section 8.9. Binding Effect. Subject to the provisions of Section 5.3,
this Agreement shall be binding upon and shall inure to the benefit of the
parties hereto and their respective successors and permitted assigns.
