                                 INTRODUCTION
 
  The Trust is a no-load, diversified, open-end management investment company
organized as a Massachusetts business trust pursuant to an Agreement and
Declaration of Trust dated December 4, 1981 ("Trust Agreement"). The Trust is
designed to provide a convenient means of investing funds where the direct
purchase of money market instruments may be undesirable or impractical. An
investment in the Trust permits participation in money market instruments
(with maturities not exceeding one year from date of acquisition) while
relieving the investor of most details associated with the direct purchase of
money market instruments, such as the need to maintain bookkeeping records, to
make frequent investment decisions, to schedule maturities and to provide for
safekeeping. "No-load" means that the Trust imposes no commissions or charges
when its Shares are purchased or redeemed.
 
                INVESTMENT OBJECTIVE, POLICIES AND RESTRICTIONS
 
  The Trust seeks to maximize current income to the extent consistent with
preservation of capital and maintenance of liquidity. Of course, there can be
no assurance that the Trust will achieve its investment objective.
 
  The Trust seeks to achieve its investment objective by investing exclusively
in the following types of money market instruments maturing in one year or
less from time of purchase: (1) debt securities issued or guaranteed by the
U.S. Government or by its agencies or instrumentalities (including securities
supported by the limited right of the issuer to borrow from the U.S. Treasury,
such as Federal Home Loan Bank securities, or solely by the creditworthiness
of the issuer, such as Federal National Mortgage Association debentures and
notes), and repurchase agreements/1/ with respect to any of such securities;
(2) zero coupon securities that are U.S. Treasury notes and bonds stripped of
their unmatured interest coupons, the unmatured interest coupons or interests
in such U.S. Treasury securities or coupons; (3) certificates of deposit,
variable rate certificates of deposit, time deposits, and banker's acceptances
of United States banks (excluding foreign branches) having total assets of at
least $1 billion and which are members of the Federal Deposit Insurance
Corporation; (4) commercial paper at the time of purchase rated Prime-1 by
Moody's Investors Service, Inc. ("Moody's") or A-1 by Standard & Poor's
Corporation ("S&P") or, if unrated, issued or guaranteed by a corporation with
outstanding debt rated Aa or better by Moody's or AA or better by S&P; and (5)
any other corporate notes, bonds and debentures rated Aa or better by Moody's
or AA or better by S&P at the time of purchase. In addition, the Trust limits
its investments to securities that meet the quality and diversification
requirements of Rule 2a-7 under the Investment Company Act of 1940. See the
Statement of Additional Information and its "Appendix," for a description of
commercial paper, note and bond ratings and for a more detailed description of
the money market instruments in which the Trust may invest.
 
  Generally, the Trust will invest only in securities that are considered
liquid and that are not subject to restriction as to disposition under the
federal securities laws, except that the Trust may invest in money market
instruments issued in a private placement under Section 4(2) of the Securities
Act of 1933 ("Securities Act") and may invest up to 10% of its assets in
illiquid securities. Securities issued pursuant to Section 4(2) include
instruments similar in nature to commercial paper, but which are not entitled
to the exemption afforded commercial paper by Section 3(a)(3) of the
Securities Act because they were issued to finance other than current
transactions or were issued with a maturity greater than nine months. The
Trust's investment adviser considers Section 4(2) paper generally to be
liquid. If a particular investment in Section 4(2) paper is determined not to
be liquid, however, based on specified standards, the investment will be
included within the 10% limitation on illiquid securities. The Board of
Trustees has approved guidelines and procedures adopted by the investment
adviser and has delegated the day-to-day function of determining and
monitoring the liquidity of securities to the Trust's adviser. The Board,
however, will retain oversight and be ultimately responsible for the
determination. See "Investment Objective, Policies and Restrictions" and
"Trust Investments" in the Statement of Additional Information.
 
  In addition to the Section 4(2) paper, other types of "restricted" money
market instruments that meet the Trust's credit, maturity and other investment
criteria (such as high quality bonds with less than one year remaining to
maturity) could be purchased or sold by the Trust in a private placement. The
Trust does not have a current intention to purchase such securities, but is
permitted to do so provided that investments in all securities considered
illiquid were not greater than 10%.
 
  The 10% limitation on illiquid securities also would include securities for
which a readily available market may not exist and repurchase agreements
maturing in more than seven days. For a more detailed discussion of the
Trust's investment restrictions, see the Statement of Additional Information,
"Investment Objective, Policies and Restrictions."
- -------
  /1/Repurchase agreements are instruments under which the Trust acquires
ownership of a security and the seller (a broker-dealer or bank) agrees to
repurchase the security at a mutually agreed upon time and price, thereby
determining the yield during the Trust's holding period. In the event of
bankruptcy or other default of a seller of a repurchase agreement the Trust
might have expenses in enforcing its rights, and could experience losses,
including a decline in the value of the underlying securities and loss of
income.

  It is the policy of the Trust to seek to maintain a net asset value of $1
per share, and, as a general policy, to hold securities until maturity. See
"RISKS." Pursuant to an exemptive order obtained from the Securities and
Exchange Commission and procedures adopted pursuant to Rule 2a-7, the Trust
values its assets on the basis of amortized cost which permits it, if the
investment adviser deems it advisable, to maintain a dollar weighted average
portfolio maturity of up to 90 days. The Trust may attempt, from time to time,
to increase its yield by trading to take advantage of variations in the
markets for short-term money market instruments. For additional information,
see the Statement of Additional Information, "Pricing of Shares."
 
  The foregoing investment objective, policies and restrictions (as well as
certain others specified in the Statement of Additional Information) may not
be changed without the approval of the holders of a majority of the
outstanding shares of the Trust as defined under "DESCRIPTION OF SHARES."
 
                                     RISKS
 
  While the Trust intends to invest in high quality money market instruments,
these investments are not entirely without risk. An increase in interest rates
generally will reduce the value of the Trust's investments and a decline in
interest rates generally will increase their value. Redemptions of the Trust's
Shares could necessitate the sale of securities at times when such sales would
not otherwise be desirable. Because the Trust invests exclusively in short-
term high quality money market instruments, such instruments generally may not
yield as high a level of current income as longer term or lower grade
securities which generally have less liquidity and greater fluctuation in
value. Although the Trust seeks to maintain a net asset value of $1 per share,
there is no assurance that it will be able to do so. For additional risks see
the Statement of Additional Information, "Trust Investments" and "Investment
Objective, Policies and Restrictions."
 
                              PURCHASE OF SHARES
 
  The Trust's Shares may be purchased through Wayne Hummer, 300 South Wacker
Drive, Chicago, Illinois 60606 (the "Distributor"), without a sales charge at
their net asset value next determined after an order in proper form and
payment are received. The net asset value of the Trust's Shares is determined
as of the close of trading on the New York Stock Exchange (generally 3:00 p.m.
Chicago time) on each business day and at 3:00 p.m. Chicago time on each other
day in which there is a sufficient degree of trading in the securities held by
the Trust so as to affect materially the Trust's net asset value. See "PRICING
OF SHARES."
   
  The purchase price normally is $1 per Share. The minimum initial investment
generally is $500 and subsequent investments generally must also be at least
$500. The foregoing minimum investments may be lower for custodian accounts
and accounts that are part of an employer sponsored and administered 401(K)
pension plan. The minimum initial purchase of Shares with respect to an
Individual Retirement Account, a Simplified Employee Pension Plan, a Defined
Contribution Plan or any other type of retirement plan provided by Wayne
Hummer is $500 and subsequent investments must be at least $100. The Trust
reserves the right, in its sole discretion, at any time to vary the initial
and subsequent investment minimums, to withdraw the offering or to refuse any
purchase order.     
 
  To purchase Shares, an investor who does not currently maintain a brokerage
account with Wayne Hummer must establish one. Purchases will be effected
through the investor's brokerage account and all Shares purchased are entered
and credited to the account. Payment must be made to Wayne Hummer in cash or
by check, draft or wire transfer, unless the necessary funds are already
available as a free credit balance in the account. Shares may be purchased by
mail, in person, or in the case where an investor has an adequate free credit
balance in his or her brokerage account, automatically as described below.
Shares purchased begin to earn dividends on the business day following the day
on which an investor's order is effected.
 
  Orders received by Wayne Hummer with payment prior to the close of trading
on the New York Stock Exchange (generally 3:00 p.m. Chicago time) will be
effected that business day. Orders received after that time will be effected
the next business day. In the case of an order for the purchase of Shares paid
for by check, Wayne Hummer advances federal funds, usually not later than the
next business day following receipt of an order in proper form, though the
order is effected when the check is received by Wayne Hummer as described
above. If Shares are purchased by a check which is subsequently dishonored,
Wayne Hummer has the right to redeem such Shares and to retain any dividends
or distributions made with respect thereto. "Business day" as used in this
prospectus means any day that the New York Stock Exchange and federal banks in
both Illinois and Massachusetts are open for business.
 
  Additional information on retirement plans provided by Wayne Hummer,
including a description of applicable service fees and limitations on
contributions and withdrawals, may be obtained by calling Wayne Hummer at the
telephone numbers shown on the cover of this prospectus or by writing to Wayne
Hummer, Attention: Retirement Plans Department, 300 South Wacker Drive,
Chicago, Illinois 60606. A retirement plan account may combine investments in
Trust Shares with investments in shares of Wayne Hummer Investment Trust or in
other securities purchased through Wayne Hummer.

AUTOMATIC PURCHASES
  The Trust, in conjunction with Wayne Hummer, maintains a "sweep program" for
the automatic purchase and redemption of Shares. Expenses of maintaining the
"sweep program" are borne by Wayne Hummer pursuant to a Shareholder Service
Agreement. See "MANAGEMENT OF THE TRUST." Under the program, free credit cash
balances of $100 or more arising in a Shareholder's Wayne Hummer brokerage
account are automatically invested in Shares on a specified day of each week
(currently, Friday), or if the specified day is not a business day, then on
the prior business day. Free credit balances of $500 or more arising from cash
deposits into an account from dividend and interest payments that are not to
be paid to the Shareholder in cash, or from any other source, are invested in
Shares on the day of receipt in the account if deposited in the account prior
to 3:00 p.m. Chicago time. Free credit balances of $500 or more arising from
the sale of securities that do not settle on the day of the transaction (such
as most common and preferred stock transactions) and from principal repayments
on debt securities are invested in Shares on the business day on which the
proceeds are received in the brokerage account. The automatic Share purchase
procedure, and the automatic Share redemption procedure described below, may
be suspended at any time by the Trust or Wayne Hummer. A Shareholder wishing
to terminate his or her participation in the "sweep program" may do so at any
time by notifying his or her Wayne Hummer investment executive.
 
SYSTEMATIC INVESTMENT PLAN
  Shareholders of the Trust (except retirement plan accounts) can arrange to
have a pre-authorized amount ($100 minimum) drawn on their bank checking
account and automatically invested in the Trust on a specified day of each
month. An authorization agreement which contains details of the plan can be
obtained from the Shareholder's Wayne Hummer investment executive. The
Systematic Investment Plan may be terminated by the Trust at any time and by
the Shareholder at any time by notifying his or her investment executive.
 
PAYROLL DIRECT DEPOSIT PLAN
 
  Once a Shareholder meets the Trust's minimum initial investment requirement,
additional Shares may be purchased through Payroll Direct Deposit. Through
this Plan, periodic investments (minimum $100) are made automatically from the
Shareholder's payroll check into his or her existing Trust account. By
enrolling in the Plan, the Shareholder authorizes his or her employer or its
agents to deposit a specified amount from the Shareholder's payroll check into
the Trust's bank account for the purchase of additional Shares. In most cases,
the Shareholder's Trust account will be credited the day after the amount is
received by the Trust's bank. In order to participate in the Plan, the
Shareholder's employer must have direct deposit capabilities through Automated
Clearing House available to its employees. The Plan may be used for other
direct deposits, such as social security checks, military allotments, and
annuity payments.
   
  To establish Payroll Direct Deposit, a Shareholder should call his or her
investment executive to obtain the necessary information. Once the Plan is
established, a Shareholder may alter the amount of the deposit, alter the
frequency of the deposit, or terminate participation in the Plan by notifying
his or her employer.     
 
EXCHANGE PRIVILEGE
 
  Shareholders of the Trust have the unlimited privilege (without charge) of
exchanging their Shares for shares of either the Wayne Hummer Growth Fund (
"Growth Fund") or the Wayne Hummer Income Fund ("Income Fund"), both of which
are portfolios of the Wayne Hummer Investment Trust ("Investment Trust") and
each of which operates as a separate no-load mutual fund. Similarly, shares of
either the Growth Fund or the Income Fund may be exchanged for Shares of the
Trust without charge. Exchanges may only be made, however, for shares of a
Trust which are available for sale in the Shareholder's state of residence. A
Shareholder desiring to utilize the exchange privilege should contact his or
her Wayne Hummer investment executive at the phone number or address shown on
the cover of this prospectus to obtain information about the Investment
Trust's mutual funds and exchange procedures. No guarantee can be made as to
the availability of the telephone exchange privilege (or the telephone
redemption privilege discussed below) during emergency situations or unusual
market conditions. Before exchanging Shares, Shareholders should read the
Investment Trust prospectus carefully. Exchanges will be effected through the
redemption of Shares tendered for exchange and the purchase of shares of the
either Growth Fund or the Income Fund at their respective net asset values
next determined after receipt by Wayne Hummer of the exchange request. For
federal income tax purposes, an exchange constitutes a sale with respect to
which a gain or loss may be realized depending upon whether the value of the
Shares being exchanged is more or less than the Shareholder's adjusted cost
basis.

<PAGE>
 
                             REDEMPTION OF SHARES
 
  The Trust will redeem all or any number of a Shareholder's Shares without
charge at their net asset value next determined after receipt by Wayne Hummer
of a redemption request in proper form. Except for redemptions by check,
redemption requests must be made to Wayne Hummer by telephone, mail or in
person. Shares covered by a redemption request received in proper form prior
to 3:00 p.m. Chicago time will continue to accrue dividends through the close
of business on the date of receipt. Shares covered by a redemption request
received in proper form after 3:00 p.m. Chicago time will continue to accrue
dividends through the close of business on the next business day following the
date of receipt. Redemption proceeds are normally credited to a Shareholder's
Wayne Hummer brokerage account at the start of business on the next business
day following the date through which dividends are accrued, but in no event
later than three business days after the redemption request is received. In
certain instances, redemptions may be automatically effected by Wayne Hummer
as described below.
 
REDEMPTIONS BY CHECK
  A Shareholder (except retirement plan accounts) may establish a special
checking account with State Street Bank and Trust Company for the purpose of
redeeming Shares by check. Checks may be requested from Wayne Hummer. Checks
may be written in amounts of $500 or more up to a maximum of $250,000 and may
be made payable to any party.
 
  The checkwriting procedure for redeeming Shares enables a Shareholder to
earn the dividends declared on Shares until such time as the check is
presented to State Street Bank and Trust Company which effects the redemption
on behalf of the Trust and makes payment on the check. If (1) the amount of
the check is greater than the value in a Shareholder's account, or (2) the
check is for an amount less than $500 or (3) the check is in excess of
$250,000, the check will not be honored and will be returned unpaid to the
person to whom the check was written. The Trust reserves the right to impose a
charge for the checkwriting privilege at a future date, to charge for
excessive use of the checkwriting privilege, to charge Shareholders its costs
for stop payment requests and checks returned for any reason, and to make
additional charges to recover the costs of providing the checkwriting service.
The check redemption procedure may be suspended or terminated at any time by
the Trust, Wayne Hummer or State Street Bank and Trust Company.
 
  At various times the Trust may be requested to redeem shares for which good
payment has not been received. For example, if Shares are purchased by check,
the Shareholder's check may not have been cleared through the banking system
even though Wayne Hummer has advanced federal funds to effect the purchase. In
such event, Wayne Hummer or, in the case of redemption by check, State Street
Bank and Trust Company, may delay payment for redeemed Shares for up to 15
days while the Trust awaits assurance that good payment has been collected.
 
AUTOMATIC REDEMPTIONS
 
  Redemptions of Shares will be automatically effected on a daily basis by
Wayne Hummer to satisfy debit balances of $10 or more existing in a
Shareholder's brokerage account just prior to 3:00 p.m. Chicago time. After
application of any free credit cash balances in the account to such debit
balances, the number of Shares needed to satisfy the remaining debit balance
will be redeemed at net asset value determined at 3:00 p.m. Chicago time that
day. If more than one redemption transaction is processed on a specific day
and the number of Shares available for redemption is insufficient to satisfy
all redemption transactions, redemptions by check, if presented, will take
precedence over redemption to satisfy debit balances resulting from activity
in the Shareholder's brokerage account. The automatic redemption of Shares to
settle debit balances in the brokerage account for purchases of other
securities may occur prior to the settlement date of such purchases and, thus,
the redemption proceeds may remain uninvested in the brokerage account until
such settlement date.
 
  Due to the relatively high cost of maintaining accounts of less than $500,
the Trust reserves the right to redeem involuntarily Shares in any account
(other than a retirement plan account) for their then current value if at any
time a Shareholder's total investment does not have a value of at least $500.
A Shareholder will first be notified that the value of his or her account is
less than $500 and will be allowed 60 days to make an additional investment
before the involuntary redemption is made. The proceeds of an involuntary
redemption will be credited promptly to the Shareholder's Wayne Hummer
brokerage account and, on the following business day, will be mailed to the
Shareholder by check.
 
  The Trust may suspend the right of redemption and the determination of net
asset value and may postpone the date of payment for redeemed Shares beyond
seven days under the following unusual circumstances: when the New
 
                                       6
<PAGE>
 
York Stock Exchange is closed (other than weekends and holidays) or trading is
restricted; when an emergency exists as determined by the Securities and
Exchange Commission, making disposal of portfolio securities or the valuation
of net assets not reasonably practicable; or during any period when the
Securities and Exchange Commission has by order permitted a suspension of
redemption for the protection of Shareholders. For a more detailed description
of these circumstances see the Statement of Additional Information, "Purchase
and Redemption of Shares."
 
                            MANAGEMENT OF THE TRUST
 
  Wayne Hummer Management Company (the "Investment Adviser"), 300 South Wacker
Drive, Chicago, Illinois 60606, acts as investment adviser to the Trust and
provides the Trust with operating facilities and management and portfolio
accounting services and serves as investment adviser to the Investment Trust
as well as to various individual, institutional and fiduciary accounts. The
Investment Adviser, organized in 1981, is owned by the voting members of Wayne
Hummer, a securities brokerage firm, which acts as Shareholder Service Agent
and Distributor.
 
  Subject to the general supervision of the Board of Trustees, the Investment
Adviser determines the securities to be purchased, sold and held by the Trust,
is responsible for management of the Trust's portfolio and places all orders
subject to periodic review by the Board of Trustees.
 
  As compensation for its advisory and management services to the Trust, the
Investment Adviser receives a fee from the Trust, payable monthly, at an
annual rate based on a percentage of the Trust's average daily net assets. The
annual rate of the advisory fee is .50% of the first $500 million of average
daily net assets and is reduced at several breakpoints for average daily net
assets in excess of $500 million. See the Statement of Additional Information,
"Management of the Trust--Investment Adviser." The Investment Adviser has
agreed to waive its fees to the extent that the Trust's operating expenses
during any fiscal year exceed 1% of the Trust's average daily net assets.
Expenses which are not subject to these limitations are interest, taxes,
brokerage commissions and extraordinary items.
 
  The Investment Adviser also provides the Trust with certain portfolio
accounting services under the terms of a Portfolio Accounting Services
Agreement. The Investment Adviser maintains the accounting books and records
that constitute the record forming the basis for financial statements of the
Trust; maintains the capital stock account for the Trust; prepares a daily
trial balance for the Trust and calculates its net asset value; maintains all
records of a financial nature to the Trust's transactions; and processes
special ledgers and other reports when requested. As compensation for its
accounting services to the Trust, the Investment Adviser receives an annual
fee of .01 of 1% of average daily net assets of the Trust, which is computed
and accrued daily and payable monthly; but such fee shall not exceed $15,000
per annum. In addition, the Investment Adviser receives an equipment fee of
$50 per month and is reimbursed for its out-of-pocket costs for obtaining
securities pricing services, the license for use of portfolio accounting
software, and for other out-of-pocket costs which are incurred in providing
the pricing and software services.
 
  Wayne Hummer provides services to the Trust pursuant to a Shareholder
Service Agreement. Such services, which are provided at their approximate cost
(excluding labor and overhead), if any, include such matters as: converting
funds into or advancing Federal Funds for the purchase of Shares; transmitting
purchase orders or redemption requests to the Transfer Agent; maintaining
records of Shareholders' transactions; preparing and transmitting federal and
state informational tax returns; recording Share dividends and forwarding cash
dividends to Shareholders; maintaining the automatic Share redemption and
purchase "sweep program"; generating and transmitting monthly statements; and
providing telephonic and written communications with respect to Shareholder
account inquiries.
 
                             DESCRIPTION OF SHARES
 
  The Trust's Agreement and Declaration of Trust ("Trust Agreement") permits
the Trust to issue an unlimited number of full and fractional Shares. Each
Share is without par value, represents a proportionate interest in the Trust
which is equal to the proportionate interest represented by each other Share
and is entitled to such distributions from the net investment income generated
by the Trust's investments as are declared by the Trustees. Upon the
liquidation of the Trust, Shareholders are entitled to share pro rata in the
net assets that are available for distribution. Shares do not have
 
                                      7
<PAGE>
 
cumulative voting rights nor any preemptive or conversion rights. Shares are
fully paid and nonassessable when issued as described herein, except as
expressly set forth below. Share Certificates are not issued. Shares owned and
dividends paid thereon will be reflected in each Shareholder's Wayne Hummer
monthly statement.
 
SHAREHOLDER VOTING RIGHTS
 
  As a general rule the Trust will not hold annual or other meetings of
Shareholders. Under the Trust Agreement, Shareholders are entitled to vote in
connection with the following matters: (1) for the election or removal of one
or more Trustees if a meeting is called for that purpose; (2) with respect to
the adoption of any contract for which Shareholder approval is required under
the Investment Company Act of 1940 (such as the Trust's Investment Advisory
and Management Agreement); (3) with respect to any termination of the Trust to
the extent and as provided in the Trust Agreement; (4) with respect to any
amendment of the Trust Agreement (other than amendments changing the name of
the Trust, supplying any omission, curing any ambiguity or curing, correcting
or supplementing any defective or inconsistent provision thereof); (5) as to
whether or not a court action, proceeding or claim should or should not be
brought or maintained derivatively or as a class action on behalf of the Trust
or the Shareholders, to the same extent as the stockholders of a Massachusetts
business corporation; and (6) with respect to such additional matters relating
to the Trust as may be required by law, the Trust Agreement, the By-laws of
the Trust, any registration of the Trust with the Securities and Exchange
Commission or any state, or as the Trustees may consider necessary or
desirable. Each Trustee serves until the next meeting of Shareholders and
until the election and qualification of his or her successor or until such
Trustee sooner dies, resigns, retires or is removed by vote of at least two-
thirds of the Shares entitled to vote or a majority of the Trustees.
 
ADDITIONAL PORTFOLIOS
 
  The Trust Agreement permits the Board of Trustees to issue Shares in one or
more series ("Portfolios"). Only one Portfolio is currently authorized, which
is designated as the "Money Market Portfolio." If additional Portfolios are
established, each Share of a particular Portfolio will represent an equal
proportionate interest in the assets and liabilities belonging to such
Portfolio with each other Share of that Portfolio. Should the Trust issue
Shares in two or more Portfolios, voting with respect to certain matters will
be by Portfolio (such as approval of the Investment Advisory and Management
Agreement) and with respect to other matters will be by all Shareholders
without regard to Portfolio (such as election of Trustees and the ratification
of the selection of independent auditors).
 
SHAREHOLDER LIABILITY
 
  The Trust is organized as a "Massachusetts business trust." Under
Massachusetts law, shareholders of such a trust may, under certain
circumstances, be held personally liable for the obligations of the Trust. The
Trust Agreement provides that Shareholders shall not be subject to any
personal liability to any person extending credit to, contracting with or
having any claims against the Trust and that every written agreement,
obligation, instrument or undertaking made by the Trust shall contain a
provision that the same is not binding upon the Shareholders personally. With
respect to other claims, a Shareholder may be held personally liable to the
extent that claims are not satisfied by the Trust. Upon payment of any such
liability, however, Shareholders will be entitled to reimbursement from the
general assets of the Trust. The Trust is covered by insurance which the
Trustees consider adequate to cover foreseeable tort claims. See the Statement
of Additional Information, "Shareholder Liability."
 
                               PRICING OF SHARES
 
  Shares may be purchased or redeemed at their net asset value, which normally
is $1. The net asset value per Share is computed by dividing the value of the
securities held by the Trust plus any other assets minus all liabilities by
the total number of Shares outstanding. The securities held by the Trust will
be valued using the amortized cost method of valuation. The net asset value
per Share is determined on each day the New York Stock Exchange is open for
trading as of the close of regular session trading on the Exchange (generally
3:00 p.m. Chicago time) and at 3:00 p.m. Chicago time on each other day during
which there is a sufficient degree of trading in securities of the Trust's
portfolio so as to affect materially the net asset value of the Shares. See
the Statement of Additional Information, "Pricing of Shares." Expenses,
including the fee payable to the Investment Adviser, are accrued daily.

<PAGE>
 
                            PERFORMANCE INFORMATION
   
  From time to time, in advertisements or reports to shareholders, the Trust
may quote recognized independent publishers and other sources, such as IBC
Financial Data, Inc. or similar industry services, for purposes of comparing
the Trust's rank or performance with that of other money market funds having
similar investment objectives or asset size. Performance comparisons should
not be considered representative of the future performance of the Trust.     
 
  Additionally, from time to time, the Trust may quote "yield" and "effective
yield" figures for the Trust's performance in advertisements and other
materials furnished to present or prospective shareholders. Each of these
figures is based upon historical earnings and is not necessarily
representative of the future performance of the Trust. The yield of the Trust
refers to the income generated by a hypothetical investment in the Trust over
a specific seven day period. This income is then annualized, which means that
the income generated during the seven day period is assumed to be generated
each week over an annual period and is shown as a percentage of the
investment. The effective yield is calculated similarly but, when annualized,
the income earned by the investment is assumed to be reinvested. The effective
yield will be slightly higher than the yield due to this compounding effect.
The Trust's yield and effective yield will fluctuate. See the Statement of
Additional Information, "Performance Information," for more information
concerning the Trust's performance.
 
                                   DIVIDENDS
   
  The Trust declares as daily dividends all of the Trust's undistributed net
investment income. Net investment income of the Trust is determined
immediately prior to the determination of net asset value and consists of (1)
accrued interest income plus or minus amortized purchase discount or premium,
(2) plus or minus all short-term realized and unrealized gains and losses and
(3) minus accrued expenses. The Trust does not expect to realize any long-term
gains or losses. Dividends are reinvested monthly in the form of additional
full and fractional Shares at net asset value, or at the option of the
Shareholder, are paid as cash dividends monthly by credit to the Shareholder's
brokerage account with Wayne Hummer and, generally on the business day
following such credit, paid to the shareholder by check, which check is mailed
within seven days after the end of the month in which the dividends were
declared. Dividends are taxable to Shareholders whether received in cash or
reinvested in additional Shares, as described below.     
 
                                     TAXES
 
  The Trust intends to continue to qualify as a "regulated investment company"
under the Internal Revenue Code of 1986, as amended (the "Code"), as it has
since its inception. If so qualified, the Trust will not be subject to federal
income tax on its net investment income and realized capital gains distributed
to Shareholders.
 
  Distributions of net income including any short-term capital gains are
taxable to Shareholders as ordinary income, whether such distributions are
taken in cash or reinvested in additional Shares. It is expected that none of
the Trust's distributions to Shareholders will be eligible for the dividends-
received deduction currently available to corporate Shareholders. Promptly
after the end of each calendar year, each Shareholder will receive a statement
of the federal income tax status of all distributions made during the year.
Distributions declared in October, November or December to Shareholders of
record as of a date in one of those months and paid before the following
February 1 are treated for federal income tax purposes as paid on December 31
of the calendar year declared. Shareholders are advised to consult with their
tax advisors concerning their individual tax situations.
 
  The Trust is required by law to withhold federal income tax at a rate of 31%
from taxable distributions to Shareholders who do not furnish their correct
taxpayer identification numbers (in the case of individuals, their social
security numbers) and in certain other circumstances.
                              
                           IMPACT OF YEAR 2000     
   
  Similar to other mutual funds, financial and business organizations and
individuals around the world, the Trust could be adversely affected if the
computer systems used by the Investment Adviser and other service providers do
not properly process and calculate date-related information and data from and
after January 1, 2000. This is commonly known as the "Year 2000 Problem". The
Investment Adviser is taking steps that it believes are reasonably designed to
address the Year 2000 Problem with respect to computer systems that it uses
and to obtain reasonable assurances that comparable steps are being taken by
the Trust's other major service providers. At this time, there can be no
assurance that these steps will be sufficient to avoid any adverse impact to
the Trust.

<PAGE>
 
                            REPORTS TO SHAREHOLDERS
 
  The Trust sends to its Shareholders various financial reports ("Reports")
such as unaudited semi-annual financial statements and fiscal year-end
financial statements audited by the Trust's independent auditors. To reduce
expenses, only one copy of most Reports may be mailed to all accounts with the
same social security or taxpayer identification number or to all Shareholders

                                  BACKGROUND
 
  Wayne Hummer Money Fund Trust (the "Trust") is a no-load, diversified, open-
end management investment company organized as a Massachusetts business trust
pursuant to an Agreement and Declaration of Trust dated December 4, 1981 (the
"Trust Agreement"). The Trust Agreement authorizes the Trustees to issue one
or more series of units of beneficial interest ("Shares"). The Trust currently
offers Shares of only one series, the Money Market Portfolio.
 
                INVESTMENT OBJECTIVE, POLICIES AND RESTRICTIONS
 
  In addition to the investment objective, policies and restrictions discussed
in the prospectus, the Trust may NOT:
 
    (1) Purchase any securities other than money market instruments and
  securities described in the Trust's current prospectus or Statement of
  Additional Information;
 
    (2) Purchase the securities of issuers whose principal business is in the
  same industry (other than United States Government securities, United
  States Government agency or instrumentality securities or bank money
  instruments) if immediately after such purchase the value of the Trust's
  investments in such industry would exceed 25% of the value of its total
  assets (taken at market value at the time of each investment). For purposes
  of this subparagraph, the personal credit and business credit businesses of
  finance companies will be considered separate industries and, as to
  utilities, the water, gas, electric and telephone businesses will be
  considered separate industries;
 
    (3) Purchase the securities (other than of the United States Government,
  its agencies and instrumentalities) of any one issuer if immediately after
  such purchase more than 5% of the value of the Trust's total assets (taken
  at market value at the time of each investment) would be invested in such
  issuer, except that up to 25% of the value of the Trust's total assets may
  be invested without regard to such 5% limitation but shall instead be
  subject to a 10% limitation;(1)
 
    (4) Purchase more than 10% of any one class of an issuer's outstanding
  securities, except that such restriction shall not apply to securities of
  the United States Government, its agencies or instrumentalities,
  certificates of deposit, bankers' acceptances or repurchase agreements;
 
    (5) Make investments for the purpose of exercising control or management;
 
    (6) Make loans, except that securities owned or held by the Trust may be
  loaned pursuant to paragraph (7) below; provided, however, that the Trust
  may purchase money market securities and enter into repurchase agreements
  with banks, brokers and dealers;
 
    (7) Lend securities in excess of 20% of the Trust's total assets, taken
  at market value; provided, however, that loans not exceeding 20% of the
  Trust's total assets may be made if collateral is maintained from the
  borrower equal at all times to the current market value of the securities
  loaned;(2)
 
    (8) Purchase securities of other investment companies, except in
  connection with a merger, consolidation, acquisition or reorganization; The
  Trust did not lend its securities during the past fiscal year. There is no
  present intention to engage in the lending of Trust securities.
 
    (9) Purchase any securities on margin, except for use of short-term
  credits necessary for clearance of purchases and sales of Portfolio
  securities; make short sales of securities or maintain a short position or
  write, purchase or sell puts, calls, straddles, spreads or combinations
  thereof;
- --------
(1) Procedures adopted pursuant to Rule 2a-7 under the Investment Company Act
    of 1940 restrict the Trust generally to the 5% limitation; the 10%
    limitation will not be available so long as such procedures are in effect.
    See "PRICING OF SHARES".
(2) The Trust did not lend its securities during the past fiscal year. There
    is no present intention to engage in the lending of Trust securities.
 
                                      B-1
<PAGE>
 
    (10) Purchase or sell real estate (other than money market securities
  secured by real estate or interests therein or money market securities
  issued by companies which invest in real estate, or interests therein),
  commodities or commodity contracts, oil or gas interests or other mineral
  exploration or development programs;
 
    (11) Purchase securities of issuers (other than securities of the United
  States Government, its agencies or instrumentalities) having a record,
  together with its predecessors, of less than three years of continuous
  operation if, regarding all such securities, more than 5% of the Trust's
  total assets, taken at market value, would be invested in such securities;
 
    (12) Invest in securities restricted as to disposition under the federal
  securities laws (except money market instruments issued under Section 4(2)
  of the Securities Act);
 
    (13) Invest more than 10% of its assets in securities (including
  repurchase agreements maturing in more than seven days) which are
  considered illiquid;
 
    (14) Borrow money except from banks and only as a temporary measure for
  extraordinary or emergency purposes, but not for investment purposes nor in
  any amount exceeding 5% of the Trust's total assets, taken at market value;
 
    (15) Mortgage, pledge or hypothecate or in any manner transfer (except as
  provided in paragraph (7) above) as security for indebtedness any
  securities owned or held by the Trust except as may be necessary in
  connection with borrowings mentioned in paragraph (14) above, and then such
  mortgaging, pledging or hypothecating may not exceed 25% of the Trust's
  total assets, taken at market value;
 
    (16) Act as an underwriter of securities;
 
    (17) Purchase or retain securities of any issuer employing, as an officer
  or director, any person serving as an officer or Trustee of the Trust, or
  purchase or retain the securities of any issuer, if, to the Trustees'
  knowledge, those officers, directors or Trustees of the Trust or its
  Investment Adviser who individually either directly or indirectly own,
  control or hold with power to vote more than 0.5% of the outstanding
  securities of such issuer, together own directly or indirectly, control or
  hold with power to vote more than 5% of such outstanding securities;
 
    (18) Issue a class of securities which is senior to the Shares, except as
  provided pursuant to paragraph 14 and in accordance with the Investment
  Company Act of 1940.
 
  The restrictions set forth above may not be changed without the approval of
the holders of a majority of the Trust's Shares, as defined in the Investment
Company Act of 1940. See "SHAREHOLDER VOTING RIGHTS." In addition to the
foregoing restrictions, the Trust limits its investments to securities that
meet the quality and diversification requirements of Rule 2a-7 under the
Investment Company Act of 1940. See "PRICING OF SHARES".
       
  If any applicable percentage restriction contained in the foregoing
investment restrictions is satisfied at the time the securities subject
thereto are purchased, the fact that the percentage restriction subsequently
is exceeded due to a fluctuation in the value of such securities or of other
securities of the Trust will not require the Trust to dispose of such
securities. Notwithstanding the foregoing, if the percentage restriction
contained in paragraph (7) or paragraph (14) above is violated due to a
subsequent fluctuation in value of the Trust's portfolio of securities, the
Trust shall be entitled, as a condition which shall be a part of all loans
subject to paragraph (7) and all borrowings subject to paragraph (14), to
reduce within three business days the outstanding amount of such loans or
borrowings in order once again to satisfy such percentage restriction.
 
  Moreover, subject to the investment restriction contained in paragraph (7)
above, the Trust may from time to time loan its securities to brokers, dealers
and financial institutions and receive collateral in cash or cash equivalents
which will be maintained at all times in an amount equal to at least 100%
 
                                      B-2
<PAGE>
 
of the current value of the loaned securities. In this regard: (1) such
collateral will be invested in short-term securities, the income from which
will increase the return to the Trust; (2) the Trust will retain all rights of
beneficial ownership as to the loaned Portfolio securities, including voting
rights and rights to interest or other distributions, and will have the right
to regain record ownership of loaned securities to exercise such beneficial
rights; (3) such loans will be terminable within three business days; and (4)
upon termination of the loan, the Trust will receive securities which are of
the same class and issue as those loaned. In the event that the borrower of
such loaned securities fails financially, the Trust might experience a delay
in recovery, incur expenses in enforcing its rights and experience losses,
including a substitution of securities and loss of income. The Trust may pay
reasonable fees to persons not affiliated with the Trust, as defined in the
Investment Company Act of 1940, in connection with the arranging of such
loans.
 
                               TRUST INVESTMENTS
 
  The following is a description of the types of money market instruments in
which the Trust may invest. All securities purchased by the Trust will mature
within one year from the date of purchase.
 
  United States Government Securities are marketable debt securities which are
issued by and are a direct obligation of the United States Treasury. Treasury
securities differ in their interest rates, maturities and times of issuance:
Treasury bills have maturities of one year or less; Treasury notes have
maturities of one to 10 years; Treasury bonds generally have maturities of
greater than ten years. All Treasury securities are direct obligations of the
United States Government and generally are considered the safest forms of
investment as no borrower has a higher credit rating than the United States
Government.
 
  United States Government Agency and Instrumentality Securities are
marketable debt securities issued or guaranteed by agencies and
instrumentalities of the United States Government. Although these securities
are not direct obligations of the United States Government, some are supported
by the full faith and credit of the Treasury, such as Government National
Mortgage Association pass-through certificates; others are supported to the
extent of the right of the issuer to borrow from the Treasury, such as Federal
Home Loan Bank bonds and notes; while others solely depend on the credit of
the agency or instrumentality and not the Treasury, such as Federal National
Mortgage Association debentures and notes. There can be no assurance that the
United States Government would support an agency or instrumentality that
defaults on securities not guaranteed by the Treasury.
 
  United States Government Agencies and Instrumentalities may also issue
securities having rates of interest that are adjusted periodically or that
"float" continuously or periodically according to formulae intended to
minimize fluctuation in values of the instruments ("Variable Rate
Securities"). The interest rate on a Variable Rate Security is ordinarily
determined by reference to, or is a percentage of, an objective standard such
as a bank's prime rate, the 90-day U.S. Treasury Bill rate, or the rate of
return on commercial paper or bank certificates of deposit. Generally, the
changes in the interest rates on Variable Rate Securities reduce the
fluctuation in the market value of such securities. Accordingly, as interest
rates decrease or increase, the potential for capital appreciation or
depreciation is less than for fixed-rate obligations.
 
  The maturity of Variable Rate Securities are determined in accordance with
the Securities and Exchange Commission rules, that allow the trust to consider
certain of such instruments as having maturities shorter than the maturity
date on the face of the instrument if they are guaranteed by the U.S.
Government or its agencies or instrumentalities.
 
  Zero Coupon Bonds are purchased at a discount from the face amount. The
buyer receives only the right to receive a fixed payment on a certain date in
the future and does not receive periodic
 
                                      B-3
<PAGE>
 
interest payments. The zero coupon securities in which the Fund may invest are
U.S. Treasury notes and bonds that have been stripped of their unmatured
interest coupons, the unmatured interest coupons or interests in such U.S.
Treasury securities or coupons.
 
  Bank Money Instruments include certificates of deposit, variable rate
certificates of deposit, and bankers' acceptances.
 
  Certificates of deposit generally are short-term, interest-bearing
negotiable certificates issued by commercial banks against funds deposited in
the issuing institution.
 
  Variable rate certificates of deposit are certificates of deposit on which
the interest rate is periodically adjusted prior to their stated maturity,
usually at 30, 90 or 180 day intervals, based upon a specified market rate
which is considered by the issuers to be representative of the then-prevailing
certificate of deposit rate. As a result of these adjustments the interest
rate on these obligations may be increased or decreased periodically. Variable
rate certificates of deposit also may contain provisions whereby the issuing
banks agree to repurchase such instruments at par on any coupon date, on any
rate adjustment date, or on any date after a specified holding period.
Variable rate certificates of deposit normally carry a higher initial interest
rate than fixed rate certificates of deposit with shorter maturities because
the issuing bank pays a premium for the use of the money for a longer period
of time. With respect to variable rate certificates of deposit maturing in one
year or less from the time of purchase, the Trust uses the period remaining
until the next rate adjustment date for purposes of determining the average
weighted maturity.
 
  Bankers' acceptances are time drafts drawn on a commercial bank by a
borrower, usually in connection with an international commercial transaction
(to finance the import, export, transfer or storage of goods). The borrower,
as well as the bank which unconditionally guarantees to pay the draft at its
face amount on the maturity date, is liable for payment. Most acceptances have
maturities of six months or less and are traded in secondary markets prior to
maturity.
 
  The Trust may not invest in any security issued by a commercial bank unless
the bank is organized and operating in the United States, has total assets of
at least $1 billion and is a member of the Federal Deposit Insurance
Corporation ("FDIC"), although the securities in which the Trust invests may
not be insured by the FDIC. The Trust may not invest in money market
instruments issued by foreign banks or foreign branches of domestic banks.
 
  Short-Term Corporate Debt Instruments include both commercial paper and non-
convertible corporate debt securities with no more than one year remaining to
maturity from the date of their acquisition by the Trust.
 
  The Trust may invest in commercial paper issued in reliance on the exemption
from Section 3(a)(3) ("Section 3(a)(3) paper") of the Securities Act. Such
commercial paper is generally issued by major corporations and may be issued
only to finance current transactions and must mature in nine months or less.
Although Section 3(a)(3) paper is not restricted as to the types of investors
to whom it may be sold, it is purchased primarily by institutional investors
through investment dealers and individual investor participation in the
commercial paper market is very limited. The Trust also may invest in money
market instruments issued in reliance on the exemption from registration
afforded by Section 4(2) of the Securities Act ("Section 4(2) paper") which is
restricted as to disposition under the federal securities laws, and generally
is sold to institutional investors such as the Trust who agree that they are
purchasing the paper for investment and not with a view to a public
distribution. Any resale by the purchaser must be in an exempt transaction.
Section 4(2) paper is often resold to other institutional investors through or
with the assistance of investment dealers or on an automated trading system
operated by the National Association of Securities Dealers, Inc., thus
assisting in providing liquidity.
 
 
                                      B-4
<PAGE>
 
  The Trust's adviser believes that generally, there is no significant
difference between Section 3(a)(3) and Section 4(2) commercial paper in terms
of market or trading characteristics or of the quality of the issuers and
that, despite the legal restrictions thereon, Section 4(2) paper has typically
been no less liquid or saleable than Section 3(a)(3) paper. If a particular
investment in Section 4(2) paper is not determined by the Trust's adviser to
be liquid based on specified standards, the investment will be included within
the 10% limitation on illiquid securities. In accordance with rules of the
Securities and Exchange Commission, the Board of Trustees has approved
guidelines and procedures adopted by the Trust's adviser and has delegated the
day-to-day function of determining and monitoring the liquidity of securities
to the Trust's adviser. The Board, however, will retain oversight and be
ultimately responsible for the determination.
 
  The Trust may also make investments in non-convertible corporate debt
securities (e.g., bonds and debentures) with no more than one year remaining
to maturity from the date of their acquisition by the Trust. Corporate debt
securities with a remaining maturity of less than one year tend to become
extremely liquid and are traded as money market securities. Such issues tend
to have greater liquidity and considerably less market value fluctuations than
longer term issues.
 
  The Section 3(a)(3) paper and Section 4(2) paper investments of the Trust,
at the time of purchase, will be rated "A-1" by Standard & Poor's Corporation
and/or "Prime-1" by Moody's Investors Service, Inc. or, if not rated, issued
by companies having an outstanding debt issue rated at least "AA" by Standard
& Poor's Corporation and/or "Aa" by Moody's Investors Service, Inc. The
Trust's investments in corporate debt securities (which must have maturities
from the date of their acquisition by the Trust of one year or less) must be
rated at the time of purchase at least "AA" by Standard & Poor's Corporation
and/or "Aa" by Moody's Investors Service, Inc. See "APPENDIX" for an
explanation of the commercial paper ratings of Standard & Poor's Corporation
and Moody's Investors Service, Inc.
 
  Repurchase Agreements are instruments under which the purchaser (e.g., the
Trust) acquires ownership of the obligation (underlying security) and the
seller (a broker-dealer or bank) agrees, at the time of the sale, to
repurchase the obligation at a mutually agreed upon time and price, thereby
determining the yield during the purchaser's holding period. This results in a
fixed rate of return for the period. Repurchase agreements usually are for
short periods, frequently less than one week. The value of the underlying
securities is marked to market daily. Should the value of the underlying
securities decline, the issuer of the repurchase agreement is required to
provide the Trust with additional securities so that the aggregate value of
the underlying securities is equal to the repurchase price. The Trust may
invest in securities subject to repurchase agreements with any member bank of
the Federal Reserve System or primary dealer in United States Government
securities. In the event of bankruptcy or other default of a seller of a
repurchase agreement, the Trust might have expenses in enforcing its rights,
and could experience losses, including a decline in the value of the
underlying securities and a loss of income. Repurchase agreements may be
entered into only with respect to underlying United States Government or
United States Government agency or instrumentality securities, certificates of
deposit, commercial paper or bankers' acceptances in which the Trust may
otherwise invest, as described above.
 
  The Trust is managed so that the average maturity of all instruments in its
Portfolio (on a dollar-weighted basis) is generally between 15 and 75 days and
not more than 90 days depending upon the Investment Adviser's evaluation of
market trends and other conditions. The securities of the Trust normally
mature within six months and in no event will the Trust contain any securities
maturing more than one year from the date of acquisition.
 
  Although the Trust generally does not seek profits through short-term
trading, it may dispose of any security prior to its maturity if, on the basis
of a revised credit evaluation of the issuer or other
 
                                      B-5
<PAGE>
 
circumstances or considerations, the Investment Adviser believes such
disposition advisable. In addition, the Trust may attempt, from time to time,
to increase its yield by trading to take advantage of variations in the
markets for short-term money market instruments.

INVESTMENT ADVISER
 
  Wayne Hummer Management Company (the "Investment Adviser"), 300 South Wacker
Drive, Chicago, Illinois 60606, acts as investment adviser to the Trust and
provides the Trust with operating facilities and management services under the
terms of an Investment Advisory and Management Agreement. The Investment
Adviser was incorporated on November 30, 1981.
 
  Subject to the review of the Trustees, the Investment Adviser is responsible
for the management of the Trust and reviews the Trust's holdings in light of
its own research analysis and information from other relevant sources. The
Investment Adviser determines the securities to be purchased, sold and
- --------
(4) Mr. Moran receives no compensation for services rendered in his capacity
    as Secretary of the Trust. The law firm of Vedder, Price, Kaufman &
    Kammholz, of which he is a partner, receives compensation for legal
    services rendered to the Trust.
 
                                      B-7

held by the Trust and places all orders subject to the general supervision of
the Board of Trustees. Securities normally are purchased directly from the
issuer or from an underwriter or a market maker for money market instruments.
Usually, no brokerage commissions are paid by the Trust for such purchases.
Purchases from underwriters of securities may include a concession paid by the
issuer to the underwriter. The purchase price paid to dealers serving as
primary market makers for money market instruments may include a spread
between the bid and asked prices. During the three fiscal years ended March
31, 1998, all transactions for the Trust were at net prices and there were no
commissions paid by the Trust.     
 
  Transactions are allocated among various brokers and dealers by the
Investment Adviser in its best judgment. In placing such orders, the
Investment Adviser primarily is concerned with obtaining the best combination
of price and execution. This does not mean that the Trust must base its
execution decisions solely on whether the lowest possible price or commission
costs may be obtained. In seeking to achieve the best combination of price and
execution, an effort will be made to evaluate the overall quality and
reliability of broker-dealers and the services they provide, including their
general execution capability, reliability and integrity, willingness to take
positions in securities, general operational capabilities and financial
condition. When the execution and prices offered by two or more brokers or
dealers are comparable, the Investment Adviser may, in its discretion,
purchase and sell Portfolio securities from and to brokers or dealers that
provide the Investment Adviser with research, statistical or other services.
Such services may include advice concerning the value of securities; the
advisability of investing in, purchasing or selling securities; the
availability of securities or the purchasers or sellers of securities; and
furnishing analysis and reports concerning issuers and industries, securities,
economic factors, trends and portfolio strategy. It is not possible to place a
monetary value on such research services. Since such research and statistical
services only supplement the Investment Adviser's own research efforts and any
information received must be analyzed, weighed and reviewed by the Investment
Adviser's staff, the receipt of such information is not expected materially to
reduce the Investment Adviser's cost of performing its advisory contract with
the Trust. The information received may be used by the Adviser for its other
clients and/or made available to Wayne Hummer for use in serving its
customers. Additionally, information available to Wayne Hummer may be made
available to the Investment Adviser in serving the Trust and its other
clients. Portfolio securities will not be purchased from or sold to Wayne
Hummer or the Investment Adviser or an affiliate, as defined in the Investment
Company Act of 1940, of either, except pursuant to special procedures adopted
under Rule 17a-7 promulgated under the Investment Company Act of 1940.
 
  Investment decisions for the Trust are reached independently from those for
Wayne Hummer Investment Trust ("WHIT"), the other investment company managed
by the Investment Adviser, or other of the Investment Adviser's clients
("Clients"). WHIT and/or Clients may also make investments in money market
instruments at the same time as the Trust. When the Trust, WHIT and/or Clients
have funds available for investment in money market instruments, the
Investment Adviser, to the extent permitted by applicable laws and
regulations, may aggregate the securities to be sold or purchased in order to
obtain the best combination of price and execution. In such event, allocation
of the securities so purchased or sold, as well as the costs incurred in a
transaction, will be made by the Investment Adviser in a manner it considers
to be equitable and consistent with its fiduciary obligations to the Trust,
WHIT and/or its Clients. In some cases this procedure may affect the size or
price of the position available to the Trust. It is the opinion of management
of the Trust that the benefits available outweigh any disadvantages that may
arise from concurrent transactions.
 
  The principal executive officers and directors of the Investment Adviser are
as follows:
 
    Harry Flagg Baum, Director; Steven R. Becker, Director; G. Ted Becker,
  Treasurer; Philip M. Burno, Director; Philip Wayne Hummer, Director and
  Chairman; David P. Poitras, Vice President; William A. Rogers, Director and
  Secretary; Thomas J. Rowland, President; Mark H. Dierkes, Vice President;
  and Damaris E. Martinez, Vice President, Administration.

  For the fiscal years ended March 31, 1998, 1997 and 1996, the Trust incurred
total advisory fees amounting to $1,311,192, $1,097,662 and $976,895,
respectively.     
   
  The Investment Adviser has agreed to waive its advisory fee to the extent
that the Trust's ordinary operating expenses, including the fee of the
Investment Adviser, exceed 1% of the average daily net assets of the Trust,
computed on an annual basis. Expenses which are not subject to this limitation
are interest, taxes, brokerage commissions and extraordinary items such as
litigation costs. No reimbursement by the Investment Adviser was required for
the last three fiscal years.     
 
  The Investment Adviser is obligated, among other things: to provide
investment advisory services; to furnish administrative services, office space
and basic facilities for management of the Trust's affairs; to pay the
compensation of all officers and other personnel of the Trust for their
services to the Trust as well as of the Trustees of the Trust who are
interested persons, as defined in the Investment Company Act of 1940. The
Trust pays all other expenses incurred in the operation of the Trust
including, among other things: brokerage commissions and transaction costs in
connection with the purchase and sale of the Trust's portfolio of securities;
taxes; expenses for legal, auditing and accounting services; costs of
preparing, typesetting, printing and mailing prospectuses, Shareholder
reports, proxy materials and notices to Shareholders of the Trust; charges of
the Custodian, Transfer Agent and Shareholder Service Agent; premiums for
insurance carried by the Trust pursuant to the requirements of Section 17(g)
or permissible under any other provision of the Investment Company Act of 1940
and the regulations promulgated thereunder; expenses related to the issuance
or redemption of Shares; expenses of registering, qualifying and maintaining
registration and qualification of Shares for sale under federal, state and
other laws; costs of conducting Shareholder relations; fees and out-of-pocket
expenses of Trustees who are not interested persons, as defined in the
Investment Company Act of 1940; expenses incidental to holding meetings of the
Trust's Shareholders, including proxy solicitations therefor, as well as
expenses incidental to holding meetings of the Board of Trustees and
committees of the Board of Trustees; interest expenses; costs of transactions
in portfolio securities; costs incidental to generating and mailing
confirmations and monthly statements; the allocated portion of fees and
expenses incurred in connection with any investment company organization or
trade association of which the Trust may be a member; and other expenses
properly payable by the Trust. Certain of these expenses will be incurred on
behalf of the Trust by the Investment Adviser or by Wayne Hummer as
Distributor or Shareholder Service Agent and will be reimbursed to such party
by the Trust at approximately such party's cost.
   
  The Investment Advisory and Management Agreement (the "Advisory Agreement")
was approved (i) at the May 1, 1998 meeting of the Board of Trustees by a
majority of the Trustees who are neither interested persons, as defined in the
Investment Company Act of 1940, nor parties to the Advisory Agreement, and
(ii) by the Shareholders of the Trust at the meeting of Shareholders held
December 13, 1990. The Advisory Agreement has been approved by the Trustees as
specified above for     
 
                                      B-9
<PAGE>
 
   
continuance until July 31, 1999. Unless earlier terminated as described below,
the Advisory Agreement thereafter will continue in effect from year to year if
approved annually (1) by the Trustees of the Trust or by a majority of the
outstanding voting Shares of the Trust and (2) by a majority of Trustees who
are not parties to such Agreement or interested persons, as defined in the
Investment Company Act of 1940, of any such party. The Advisory Agreement is
not assignable and may be terminated without penalty on 60 days' written
notice at the option of either party thereto or by the vote of the
Shareholders.     
 
  The Investment Adviser also provides the Trust with certain portfolio
accounting services under the terms of a Portfolio Accounting Services
Agreement (the "Accounting Agreement"). The Investment Adviser maintains the
accounting books and records that constitute the record forming the basis for
financial statements of the Trust; maintains the capital stock account for the
Trust; prepares a daily trial balance for the Trust and calculates its net
asset value; maintains all records of a financial nature to the Trust's
transactions; and processes special ledgers and other reports when requested.
   
  Under the Accounting Agreement in effect since November 1, 1994, the
Investment Adviser receives as compensation for its accounting services to the
Trust, an annual fee which is computed and accrued daily and payable monthly.
The Investment Adviser receives an annual fee of .01 of 1% of average daily
net assets; but such fee shall not exceed $15,000 per annum. In addition, the
Investment Adviser receives an equipment fee of $50 per month and is
reimbursed for its out-of-pocket costs for obtaining securities pricing
services, the license for use of portfolio accounting software, and other out-
of-pocket costs which are incurred in providing the pricing and software
services. For the fiscal years ended March 31, 1998, 1997 and 1996, the total
portfolio accounting services fees incurred by the Trust were $24,602, $21,852
and $17,844, respectively.     
 
  The Accounting Agreement was approved at the October 25, 1994 meeting of the
Board of Trustees by a majority of the Trustees who are neither parties to the
Accounting Agreement nor interested persons, as defined in the Investment
Company Act of 1940, of any such party. The Accounting Agreement shall
continue in effect until terminated. The Accounting Agreement may be
terminated by either party upon sixty days' prior written notice; provided,
however, that the Trust may terminate the Accounting Agreement without prior
notice in order to preserve the integrity of its records from material and
continuing errors and omissions on the part of the Investment Adviser.
 
RELATIONSHIP OF THE TRUST, WAYNE HUMMER AND WAYNE HUMMER MANAGEMENT COMPANY
 
  The shareholders of the Investment Adviser are the voting members of Wayne
Hummer, who own shares in proportion to their percentages of voting membership
interest. Wayne Hummer with offices at 300 South Wacker Drive, Chicago,
Illinois 60606, has been engaged in the securities brokerage business since
1931.
 
  Wayne Hummer provides services to the Trust pursuant to a Shareholder
Service Agreement. Such services are provided at their approximate cost
(excluding labor and overhead), if any, and include the following: (1)
converting funds into or advancing Federal Funds for the purchase of Shares as
well as transmitting purchase orders to the Transfer Agent; (2) maintaining
records of Shareholders' transactions for federal and state tax and securities
law purposes as well as for other purposes; (3) preparing and transmitting
federal and state tax informational returns relating to Share transactions to
Shareholders and governmental agencies; (4) recording dividends on
Shareholders' brokerage accounts with Wayne Hummer and forwarding cash
dividends to Shareholders; (5) generating and transmitting transaction
confirmations (if required) and monthly statements to Shareholders; (6)
transmitting redemption requests to the Transfer Agent and transmitting the
proceeds of redemption of Shares pursuant to Shareholder instructions when
such redemption is effected other than in connection with the checkwriting
privilege; (7) transmitting proxy materials and reports to the Trust's
 
                                     B-10
<PAGE>
 
   
Shareholders; (8) maintaining the automatic Share purchase and redemption
"sweep program" as described in the Trust's prospectus; and (9) providing
telephonic and written communications with respect to Shareholder account
inquiries. For the three fiscal years ended March 31, 1998, 1997 and 1996, the
Trust reimbursed the Shareholder Service Agent $136,200, $127,739 and
$120,930, respectively.     
 
  Wayne Hummer also acts as the sole Distributor of the Trust's Shares
pursuant to a Distribution Agreement. The terms of the Distribution Agreement
as to continuation, termination and assignment are identical to those of the
Investment Advisory and Management Agreement described above, except that the
Distributor may only terminate the Distribution Agreement upon 90 days'
written notice to the Trust. The Distribution Agreement provides that the
Distributor will hold itself available to receive or will arrange to receive
orders for Shares which continuously will be issued by the Trust and that the
Distributor pays all costs and expenses in connection with the distribution of
the Trust's Shares. The Distributor is not obligated thereunder to sell any
certain number of Shares.
 
  As of January 1, 1991 the Investment Adviser entered into an Agreement with
Wayne Hummer whereby the Investment Adviser agreed to pay to Wayne Hummer the
following: (a) for distribution services rendered to the Trust under the
Distribution Agreement, an amount equal to 35% of the gross revenues generated
from the rendering of investment advisory services to the Trust, not to exceed
in the aggregate for a particular fiscal year, however, the net profit (before
taxes and before payment of the fees so payable) earned by the Investment
Adviser for such year for the rendering of such advisory services, and (b) for
services rendered by Wayne Hummer to Trust Shareholders under the Shareholder
Service Agreement, an amount equal to 130% of the unreimbursed overhead and
labor expenses incurred by Wayne Hummer in rendering such services. The
Agreement also provides for similar payments to be made by the Investment
Adviser to Wayne Hummer for distribution and shareholder services rendered to
WHIT and its shareholders.

                       PURCHASE AND REDEMPTION OF SHARES
 
  Please refer to the description of procedures for the purchase and
redemption of Shares contained in the prospectus under "Purchase of Shares"
and "Redemption of Shares," which are incorporated herein by reference.
 
  With regard to the checkwriting redemption privilege described in the
prospectus, it should be noted that checks which have been honored will be
returned periodically to Shareholders by Wayne Hummer. A check representing a
redemption request will be processed ahead of any other redemption
instructions issued by a Shareholder and before any automatic redemptions are
effected in a Shareholder's account pursuant to the "sweep program" as
described in the prospectus under "Redemption of Shares." The check redemption
procedure may be suspended or terminated at any time by the Trust, Wayne
Hummer or State Street Bank and Trust Company.
 
  There is no charge to the Shareholder for normal use of the check redemption
privilege other than as set forth below. The Trust may charge Shareholders its
costs (currently $5) for (1) each stop payment; (2) each check written for an
amount under $500; (3) each check written in excess of $250,000; and (4) each
check returned because there are insufficient Shares in the account against
which the check is drawn. In addition, the Trust reserves the right to impose
a charge for the checkwriting privilege at a future date, to charge for
excessive use of the checkwriting privilege and to make additional charges to
recover the costs of providing this service. All charges will be deducted from
any existing or future credit balance in the Shareholder's Wayne Hummer
brokerage account.
 
  By opening an account with Wayne Hummer, a Shareholder is agreeing with the
Trust and Wayne Hummer that neither the Trust nor Wayne Hummer is responsible
for the authenticity of redemption instructions or the delivery of the
redemption proceeds by check from Wayne Hummer.
 
  Redemption requests made other than by check normally will be credited to a
Shareholder's Wayne Hummer brokerage account on the business day after the
redemption request is effective. If, at the time the redemption request is
made, a Shareholder has requested that Wayne Hummer transmit the proceeds of
redemption by mail, the proceeds normally will be mailed on the day they are
credited to the Shareholder's Wayne Hummer brokerage account, or, if the
request to transmit the proceeds by mail is made subsequent to the request to
redeem, on the next business day after receipt of the Shareholder's request to
transmit the proceeds by mail; but in either event, payment will be made
within three business days after the redemption is effective or the request to
transmit proceeds is made, respectively.
 
  The right to receive payment or the right to redeem Shares may be suspended
for more than seven days (1) for any period (a) during which the New York
Stock Exchange is closed other than customary weekend and holiday closings or
(b) during which trading on the New York Stock Exchange is restricted; (2) for
any period during which an emergency exists as a result of which (a) disposal
by the Trust of securities owned by it is not reasonably practicable or (b) it
is not reasonably practicable for the Trust fairly to determine the value of
its net assets; or (3) for such other periods as the Securities and Exchange
Commission may by order permit for the protection of Shareholders of the
Trust. The rules and regulations promulgated by the Securities and Exchange
Commission shall be used to determine the conditions under which trading shall
be deemed to be restricted within the meaning of (1) above and an emergency
shall be deemed to exist within the meaning of (2) above.
 
  The value of a Shareholder's investment at the time of redemption may be
more or less than his initial cost, but normally will be $1 per Share,
depending principally on the value of the securities held in the Trust at such
time.
 
  The Trust has made an election pursuant to Rule 18f-1 under the Investment
Company Act of 1940 to enable the Trust to elect to limit payments in cash for
large redemptions. Under the provisions
 
                                     B-12
<PAGE>
 
of Rule 18f-1, the Trust may limit cash redemptions with respect to each
Shareholder during any 90-day period to the lesser of (1) $250,000 or (2) 1%
of the net asset value of the applicable Portfolio at the beginning of such
period. If deemed advisable by the Board of Trustees, the Trust may pay the
redemption price in excess of the amounts described above in whole or in part
in securities owned by the applicable Portfolio. The market value of such
securities shall be determined as of the close of trading on the New York
Stock Exchange on the business day on which the redemption is effective. In
such case a Shareholder might incur transaction costs if he or she sold the
securities received.
 
                               PRICING OF SHARES
 
  The net asset value per Share of the Trust is determined on each day the New
York Stock Exchange is open for trading as of the close of trading on the
Exchange (generally 3:00 p.m. Chicago time) immediately after dividends have
been declared on each business day and at 3:00 p.m. Chicago time on each other
day during which there is a sufficient degree of trading in securities held by
the Trust so as materially to affect the net asset value of the Shares. The
net asset value per Share normally is $1.00. The net asset value per Share is
computed by dividing the value of the securities held by the Trust plus any
other assets minus all liabilities by the total number of Shares outstanding.
 
  The Securities and Exchange Commission has issued an order of exemption from
certain provisions of the Investment Company Act of 1940 to the extent
necessary to permit the Trust to use the amortized cost method of valuing its
Portfolios' securities. As a condition of the order of exemption and pursuant
to Rule 2a-7 promulgated by the Securities Exchange Commission and Procedures
adopted by the Trust's Board of Directors pursuant thereto, the Trust will (1)
maintain a dollar-weighted average Portfolio maturity of 90 days or less, (2)
purchase only instruments having remaining maturities of one year or less, and
(3) limit Portfolio investments, including repurchase agreements, to those
United States dollar-denominated instruments which the Board of Trustees
determines present minimal credit risks, and which are of high quality, as
determined by any major rating service or, in the case of any instrument that
is not rated, of comparable quality as determined by the Board of Trustees.
The Trust, however, further will limit its investments as described under
"TRUST INVESTMENTS" above and under "INVESTMENT OBJECTIVE, POLICIES AND
RESTRICTIONS" in this Statement of Additional Information and in the
Prospectus.
 
  The valuation of the securities held by the Trust is based upon their
amortized cost, which does not take into account unrealized securities gains
or losses. This involves valuing an instrument at its cost and thereafter
assuming a constant amortization to maturity of any discount or premium,
regardless of the impact of fluctuating interest rates on the market value of
the instrument. While this method provides certainty in valuation, it may
result in periods during which the value of an instrument, as determined by
amortized cost, is higher or lower than the price the Trust would receive if
it sold the instrument. During such periods the yield to investors in the
Trust may differ somewhat from that obtained in a similar entity which uses
available indications as to market value to value its portfolio securities.
For example, if the use of amortized cost resulted in a lower (higher)
aggregate Trust value on a particular day, a prospective investor in such
Trust could obtain a somewhat higher (lower) yield and ownership interest than
would result from investment in such similar entity and existing investors
would receive less (more) investment income and ownership interest. The Trust
expects, however, that the procedures referred to in the following paragraphs
of this section will tend to minimize the differences referred to above.
 
  The Trustees have established procedures designed to stabilize, to the
extent reasonably possible, the Trust's price per Share, as computed for the
purpose of sales and redemptions, at $1.00. Such procedures include review of
the securities holdings by the Trustees, at such intervals as they may deem
appropriate, to determine whether the net asset value per Share of the Trust
calculated by using available market quotations or market equivalents deviates
more than .50% from $1.00 per
 
                                     B-13
<PAGE>
 
Share based on amortized cost and, if so, whether such deviation may result in
material dilution or is otherwise unfair to investors or existing
Shareholders. In such review, investments for which market quotations are
readily available will be valued at the most recent bid-asked mean or yield
equivalent for such securities or for securities of comparable maturity,
quality and type, as obtained from one or more of the major market makers for
the securities to be valued. If market quotations are not readily available
for an investment, the investment will be valued pursuant to a security
valuation matrix system that classifies investments by type, days to maturity
and quality and which system is considered dependable in producing a fair
value of such investments.
 
  To the extent that any deviation between the Trust's net asset value based
upon available market quotations or market equivalents and $1.00 per Share
based on amortized cost exceeds .50%, the Trustees promptly will consider what
action, if any, will be initiated. In the event the Trustees determine that a
deviation exists which may result in material dilution or other unfair results
to investors or existing Shareholders, the Trustees have agreed to take such
corrective action as they consider necessary and appropriate, including the
sale of Trust instruments prior to maturity to realize gains or losses or to
shorten average portfolio maturity, withholding dividends or payment of
distributions, redeeming Shares in kind, or establishing a net asset value per
Share by using available market quotations or by using estimates of value
reflecting current market conditions selected by the Board of Trustees as
appropriate indicators of value. In addition, in the event that the Trust
incurs a loss or liability which the Trustees determine to be significant with
respect to the maintenance of a net asset value of $1.00 per Share, the
Trustees shall have the power (1) to reduce the number of Shares of the Trust
by that number of Shares which represents the amount of such loss or liability
by reducing the number of Shares of each Shareholder on a pro rata basis, (2)
to offset the pro rata amount of such loss or liability from the accrued
dividend account of each Shareholder, and/or (3) to establish an account in
the amount of such loss or liability and to offset such account and to defer
the declaration of dividends until sufficient income is obtained to reduce
such account to zero. There can be no assurance that the Trust will be able to
maintain a stable net asset value of $1.00 per share.
 
                           SHAREHOLDER VOTING RIGHTS
 
  Please refer to the section of the Prospectus entitled "Description of
Shares--Shareholder Voting Rights," which information is incorporated herein
by reference. That section sets forth a general rule that the Trust will not
hold annual or other meetings of Shareholders but specifies several matters in
connection with which the Shareholders are entitled to vote, including "the
election or removal of one or more Trustees if a meeting is called for that
purpose." In this regard and in accordance with the Investment Company Act of
1940 (i) the Trust will hold a Shareholder's meeting for the election of
Trustees at such time as less than a majority of the Trustees holding office
have been elected by Shareholders, and (ii) if, as a result of a vacancy in
the Board of Trustees, less than 2/3 of the Trustees holding office have been
elected by the Shareholders, that vacancy will only be filled by a vote of the
Shareholders. In addition, Trustees may be removed from office by a vote of
the holders of at least 2/3 of the outstanding Shares at a meeting duly called
for that purpose, which meeting shall be held upon the written request of the
holders of not less than 10% of the outstanding Shares. Upon the written
request of the holders of Shares having a net asset value of $25,000 or
constituting 1% of the outstanding Shares stating that such Shareholders wish
to communicate with the other Shareholders for the purpose of obtaining the
signatures necessary to demand a meeting to consider removal of a Trustee, the
Trust has undertaken to provide a list of Shareholders or to disseminate
appropriate materials (at the expense of the requesting Shareholders).
 
  The Trust Agreement permits the Trustees to issue Shares in one or more
Portfolios. Only one Portfolio currently is authorized. Should more than one
Portfolio be issued, however, the Trust Agreement provides that on any matter
submitted to a vote of the Shareholders, all Shares entitled to vote,
irrespective of Portfolio, shall be voted in the aggregate and not by
Portfolio except as otherwise
 
                                     B-14
<PAGE>
 
required by the Investment Company Act of 1940. The Trust Agreement also
expressly permits the Trustees to terminate the Trust without Shareholder
approval by notice to the Shareholders. The Investment Company Act of 1940,
however, prohibits an investment company from changing the nature of its
business so as to cease to be an investment company unless such action is
authorized by the vote of a majority of its outstanding shares.
 
  As used in the Prospectus and this Statement of Additional Information, the
term "majority of the outstanding Shares" of either the Trust or a particular
Portfolio of the Trust means the vote of the lesser of (1) the holders of 67%
or more of the Shares of the Trust or such Portfolio present at a meeting, if
the holders of more than 50% of the outstanding Shares of the Trust or such
Portfolio are present or represented by proxy, or (2) the holders of more than
50% of the outstanding Shares of the Trust or such Portfolio.
 
                             SHAREHOLDER LIABILITY
 
  Please refer to the section of the Prospectus entitled "Description of
Shares--Shareholder Liability" which is incorporated herein by reference.
 
  The Trust Agreement provides that Shareholders shall not be subject to any
personal liability to any person extending credit to, contracting with or
having any claims against the Trust and that every written agreement,
obligation, instrument or undertaking made by the Trust shall contain a
provision that the same is not binding upon the Shareholders personally. The
law firm of Ropes & Gray, Boston, Massachusetts, which supervised the
organization of the Trust under Massachusetts law, is of the opinion that,
pursuant to Massachusetts law, Shareholders will not be liable personally for
contract claims under any such agreement, obligation, instrument or
undertaking governed by Massachusetts law and containing such provision when
adequate notice of such provision is given.
 
  The Trustees intend to conduct the operations of the Trust, with the advice
of counsel, in such a way so as to avoid, as far as possible, ultimate
liability of the Shareholders for liabilities of the Trust. The Trust is
covered by insurance which the Trustees consider adequate to cover foreseeable
tort claims.
 
                            LIMITATION OF LIABILITY
 
  The Trust Agreement provides that the Trust shall indemnify the Trustees and
Officers of the Trust against liability arising in connection with the affairs
of the Trust to the fullest extent permitted by law. The Trust Agreement also
provides that all third persons shall look solely to the Trust property for
satisfaction of claims arising in connection with the affairs of the Trust.
 
                                 OTHER MATTERS
 
  The Trust is not required to issue share certificates. Unless terminated by
vote of Shareholders holding at least a majority of the Shares entitled to
vote or by the Trustees by written notice to the Shareholders, the Trust will
continue without limitation as to duration. A Portfolio may be terminated at
any time by vote of Shareholders holding at least a majority of the Shares of
such Portfolio entitled to vote or by the Trustees by written notice to the
Shareholders of such Portfolio.
 
                                  TRUST NAME
 
  Pursuant to an agreement with the Investment Adviser, the Trust has been
granted a non-exclusive license ("License") to use the trade name and service
mark "Wayne Hummer" (the "Name"), without charge for as long as the Trust is
solvent, Wayne Hummer Management Company is the
 
                                     B-15
<PAGE>
 
Investment Adviser to the Trust and Wayne Hummer & Co. is the Distributor. If
Wayne Hummer Management Company ceases to act as Investment Adviser or if
Wayne Hummer ceases to act as Distributor, then the Trust will be required to
change its name within 90 days of written notice from Wayne Hummer Management
Company and the Trust will be required to adopt a new Trust name, amend its
Trust Agreement to accomplish a change of Trust name, and deliver to Wayne
Hummer Management Company for destruction all materials in which the Name is
used. Wayne Hummer Management Company may exercise control over use of the
Name and the Trust has agreed to indemnify Wayne Hummer Management Company
against expenses or losses which may arise from the Trust's misuse of the Name
or out of any breach of the License regarding the use of the Name.
 
                            PERFORMANCE INFORMATION
   
  As described in the Prospectus, the Trust's historical performance may be
shown in the form of "yield" or "effective yield." The Trust's yield is
computed in accordance with a standard method prescribed by rules of the
Securities and Exchange Commission. Under that method, the yield quotation is
based on a seven-day period and is computed as follows: The Trust's net
investment income per share (accrued interest on portfolio securities, plus or
minus amortized purchase discount or premium, less accrued expenses) is
divided by the price per share (expected to remain constant at $1.00) at the
beginning of the period ("base period return") and the result is divided by
seven and multiplied by 365 and the resulting yield figure is carried to the
nearest one hundredth of one percent. The Trust's yield for the seven-day
period ended March 31, 1998 was 4.91%.     
   
  The Trust's effective yield is determined by taking the base period return
(computed as described above) and calculating the effect of assumed
compounding. The formula for the effective yield is: [(base period return + 1)
365/7] - 1. The Trust's effective yield for the seven-day period ended March
31, 1998 was 5.01%.     
 
  Realized capital gains or losses and unrealized appreciation or depreciation
of the Trust's investments are not included in the calculation of yield or
effective yield. The Trust's yield fluctuates, and the publication of an
annualized yield quotation is not a representation as to what an investment in
the Trust will actually yield for any given future period. Actual yields will
depend not only on changes in interest rates on money market instruments
during the period in which the investment in the Trust is held, but also on
such matters as Trust expenses.
 
  Yield fluctuations may reflect changes in the Trust's net income, and
portfolio changes resulting from net purchases or net redemptions of the
Trust's shares may affect the yield. Accordingly, the Trust's yield may vary
from day to day, and the yield stated for a particular past period is not
necessarily representative of its future yield. Since the Trust uses the
amortized cost method of net asset value computation, it does not anticipate
any change in yield resulting from any unrealized gains or losses or
unrealized appreciation or depreciation not reflected in the yield
computation, or change in net asset value during the period used for computing
yield. If any of these conditions should occur, yield quotations would be
suspended. The Trust's yield is not guaranteed, and its principal is not
insured. Although the Trust uses its best efforts to maintain its net asset
value at $1.00 per share, there can be no assurance that it will be able to do
so.
   
  In addition, the Trust's performance may be compared to that of other money
market mutual funds tracked by Lipper Analytical Services, Inc., a widely used
independent research firm which ranks mutual funds by overall performance,
investment objectives and assets and by IBC Financial Data, Inc., which
reports on money market funds.     
 
  The Trust's performance also may be compared to various bank products,
including the average rate of bank and thrift institution money market deposit
accounts, Super N.0.W. accounts, passbook savings accounts and 6-month
maturity certificates of deposit. Account minimums for money market
 
                                     B-16
<PAGE>
 
deposit accounts and Super N.0.W. accounts range upward from $2,000 and
compounding methods may vary. Super N.0.W. accounts generally offer unlimited
check writing while money market deposit accounts generally restrict the
number of checks that may be written. Bank and thrift institution deposit
accounts may be insured by the Bank Insurance Fund or Savings Association
Insurance Fund. Shareholder accounts in the Trust are not insured.
Additionally, bank passbook savings accounts compete with money market mutual
fund products with respect to certain liquidity features but may not offer all
of the features available from a money market mutual fund, such as check
writing. Bank checking accounts normally do not pay interest but compete with
money market mutual fund products with respect to certain liquidity features
(e.g., the ability to write checks against the account). Bank certificates of
deposit may offer fixed or variable rates for a set term. Withdrawal of these
deposits prior to maturity will normally be subject to a penalty. In contrast,
shares of the Trust are redeemable at net asset value (normally $1.00 per
share) next determined after a request is received, without charge.
 
  Investors may also want to compare the Trust's performance to that of United
States Treasury Bills or Notes because such instruments represent alternative
income producing products. Treasury obligations are issued in selected
denominations. Rates of Treasury obligations are fixed at the time of issuance
and payment of principal and interest is backed by the full faith and credit
of the United States Treasury. The market value of such instruments will
generally fluctuate inversely with interest rates prior to maturity and will
equal par value at maturity. Generally the values of obligations with shorter
maturities will fluctuate less than those with longer maturities. The Trust's
yield will fluctuate. Also, while the Trust seeks to maintain a net asset
value per share of $1.00, there is no assurance that it will be able to do so.
 
                                   DIVIDENDS
 
  The Trust declares as daily dividends all of the Trust's undistributed net
investment income. The Trust's net investment income for dividend purposes is
determined by the Investment Adviser immediately prior to the determination of
net asset value per Share. See "PRICING OF SHARES" above and in the
prospectus. Net investment income of the Trust (from the time of the
immediately preceding determination thereof) consists of (1) accrued interest
income plus or minus amortized purchase discount or premium, (2) plus or minus
all short-term realized and unrealized gains and losses and (3) minus accrued
expenses (including the fees payable to the Investment Adviser). The Trust
does not expect to realize any long-term gains or losses. Dividends are
declared daily and reinvested monthly in the form of additional full and
fractional Shares at net asset value, or at the option of the Shareholder, are
paid as cash dividends monthly by credit to a Shareholder's brokerage account
with Wayne Hummer. Dividends are taxable to Shareholders whether received in
cash or reinvested in additional Shares, as described below. See "TAXES."
 
                                     TAXES
 
  Please refer to information concerning taxes which is found in the
Prospectus under the headings "Dividends" and "Taxes," which is incorporated
by reference herein.
 
FEDERAL INCOME TAX
   
  The Trust intends to continue to qualify as a regulated investment company
under the Internal Revenue Code of 1986, as amended, as it has since its
inception. If so qualified, the Trust will not be subject to federal income
tax to the extent that it distributes its net investment income and realized
capital gains. Distributions of net income including any short-term capital
gains are taxable to Shareholders as ordinary income, whether such
distributions are received in cash or reinvested in additional Shares. No
distributions made by the Trust are expected to qualify for the dividends-
received deduction available to corporate Shareholders.     
 
                                     B-17
<PAGE>
 
OTHER TAXES
 
  The Trust may be subject to tax in certain states where it does business.
Further, in those states which have income tax laws, the tax treatment of the
Trust and of Shareholders with respect to distributions by the Trust may
differ from federal income tax treatment. In particular, distributions may be
subject to state and local income taxes as dividend or interest income even
though a substantial portion of such distributions may be derived from
interest on United States Government instruments which might be exempt from
such taxes if received directly by the Shareholder. Shareholders are advised
to consult their own tax advisers regarding specific questions as to federal,
state or local taxes.
 
                             INDEPENDENT AUDITORS
 
  The Trust's independent auditors are Ernst & Young LLP, 233 South Wacker
Drive, Chicago, Illinois 60606, who audit and report on the Trust's annual
financial statements, review certain regulatory reports and the Trust's
federal income tax return, and perform other professional accounting,
auditing, tax and advisory services when engaged to do so by the Trust. The
selection of independent auditors is subject to ratification by the Trust's
Shareholders should a meeting of Shareholders be held.
 
              CUSTODIAN AND TRANSFER AND DIVIDEND CREDITING AGENT
 
  State Street Bank and Trust Company, 225 Franklin Street, Boston,
Massachusetts 02110, acts as Custodian for the Trust's assets and as the
Trust's Transfer and Dividend Crediting Agent.
 
  The Custodian is responsible for holding all securities and cash of the
Trust, receiving and paying for securities purchased, delivering securities
sold upon payment therefor, receiving and collecting income from investments,
making all payments covering expenses of the Trust, and performing other
administrative duties, all as directed by authorized persons. The Custodian
does not exercise any supervisory function in such matters as purchase and
sale of portfolio securities, payment of dividends, or payment of expenses of
the Trust. The Trust has authorized the Custodian to deposit certain portfolio
securities in central depository systems as permitted under Federal law. The
Trust may invest in obligations of the Custodian and may purchase securities
from or sell securities to the Custodian.
 
                            REPORTS TO SHAREHOLDERS
 
  The Trust sends to its Shareholders various financial reports ("Reports")
such as unaudited semi-annual financial statements and fiscal year-end
financial statements audited by the Trust's independent auditors. To reduce
expenses, only one copy of most Reports may be mailed to all accounts with the
same social security or taxpayer identification number or to all Shareholders
in the same household. Shareholders may call or write Wayne Hummer to request
that copies of Reports be mailed to each account with a common taxpayer number
or to two or more Shareholders in the same household.
 
                           FINANCIAL STATEMENTS AND
                        REPORT OF INDEPENDENT AUDITORS
   
  The financial statements and the report of independent auditors contained in
the Trust's annual report to Shareholders entitled "Annual Financial
Statements (Audited)" for the fiscal year ended March 31, 1998 were filed with
the Securities and Exchange Commission on May 22, 1998 and are incorporated
herein by reference.

               DESCRIPTION OF COMMERCIAL PAPER AND BOND RATINGS
 
Description of Moody's Investors Service, Inc.'s two highest bond ratings:
 
  AAA--Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt-edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues.
 
  AA--Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group, they comprise what are generally known
as high-grade bonds. They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities, fluctuation of
protective elements may be of greater amplitude, or there may be other
elements present which make the long-term risks appear somewhat greater than
in Aaa securities.
 
Description of Standard & Poor's Corporation's two highest bond ratings:
 
  AAA--Bonds rated AAA are highest grade obligations. They possess the
ultimate degree of protection as to principal and interest. Marketwise they
move with interest rates, and hence provide the maximum safety on all counts.
 
  AA--Bonds rated AA also qualify as high-grade obligations and, in the
majority of instances, differ from AAA issues only in a small degree. Here,
too, prices move with the long-term money market.
 
Description of Moody's Investors Service, Inc.'s three highest commercial
paper ratings:
 
  Among the factors considered by Moody's Investors Service, Inc. in assigning
commercial paper ratings are the following: (1) evaluation of the management
of the issuer; (2) economic evaluation of the issuer's industry or industries
and an appraisal of the risks which may be inherent in certain areas; (3)
evaluation of the issuer's products in relation to competition and customer
acceptance; (4) liquidity; (5) amount and quality of long-term debt; (6) trend
of earnings over a period of ten years; (7) financial strength of a parent
company and the relationships which exist with the issuer; and (8) recognition
by the management of obligations which may be present or may arise as a result
of public interest questions and preparations to meet such obligations.
Relative differences in strength and weakness in respect to these criteria
would establish a rating in one of three classifications: Prime-1; Prime-2; or
Prime-3.
 
Description of Standard & Poor's Corporation's three highest commercial paper
ratings:
 
  Commercial paper rated "A" by Standard & Poor's Corporation has the
following characteristics: Liquidity ratios are adequate to meet cash
requirements. Long-term senior debt is generally rated "A" or better. The
issuer has access to at least two additional channels of borrowing. Basic
earnings and cash flow have an upward trend with allowance made for unusual
circumstances. Typically, the issuer's industry is well established and the
issuer has a strong position within the industry. The reliability and quality
of management are unquestioned. Relative strength or weakness of the above
factors determine whether the issuer's commercial paper is rated A-1, A-2 or
A-3.

                    INDIVIDUAL RETIREMENT CUSTODIAL ACCOUNT

Form 5305-A Under Section 408(a) of the Internal Revenue Code FORM
(REV.JAN.1998)

The Depositor whose name appears on the Application is establishing an
Individual Retirement Account under Section 408(a) to provide for his or her
retirement and for the support of his or her beneficiaries after death.

The Custodian named on the Application has given the Depositor the disclosure
statement required under Regulations Section 1.408-6.

The Depositor has assigned the trust the sum indicated on the Application.

The Depositor and the Custodian make the following agreement:

ARTICLE I

The Custodian may accept additional cash contributions on behalf of the
Depositor for a tax year of the Depositor. The total cash contributions are
limited to $2,000 for the tax year unless the contribution is a rollover
contribution described in Section 402(c), 403(a)(4), 403(b)(8), 408(d)(3), or an
employer contribution to a Simplified Employee Pension Plan as described in
Section 408(k).

ARTICLE II

The Depositor's interest in the balance in the Custodial account is
nonforfeitable.

ARTICLE III

1. No part of the Custodial funds may be invested in life insurance contracts,
   nor may the assets of the Custodial account be commingled with other property
   except in a common trust fund or common investment fund (within the meaning
   of Section 408(a)(5)).

2. No part of the Custodial funds may be invested in collectibles (within the
   meaning of Section 408(m)) except as otherwise permitted by Section 408(m)(3)
   which provides an exception for certain gold, silver, and platinum coins,
   coins issued under the laws of any state, and certain bullion.

ARTICLE IV

1. Notwithstanding any provision of this agreement to the contrary, the
   distribution of the Depositor's interest in the Custodial account shall be
   made in accordance with the following requirements and shall otherwise comply
   with Section 408(a)(6) and Proposed Regulations Section 1.408-8, including
   the incidental death benefit provisions of Proposed Regulations Section
   1.401(a)(9)-2, the provisions of which are incorporated by reference.

2. Unless otherwise elected by the time distributions are required to begin to
   the Depositor under paragraph

                                       1
<PAGE>
 
   3, or to the surviving spouse under paragraph 4, other than in the case of a
   life annuity, life expectancies shall be recalculated annually. Such election
   shall be irrevocable as to the Depositor and the surviving spouse and shall
   apply to all subsequent years. The life expectancy of a nonspouse beneficiary
   may not be recalculated.

3. The Depositor's entire interest in the Custodial account must be, or begin to
   be, distributed by the Depositor's required beginning date, April 1 following
   the calendar year end in which the Depositor reaches age 70 1/2. By that
   date, the Depositor may elect, in a manner acceptable to the Custodian, to
   have the balance in the Custodial account distributed in:

   (a) A single sum payment.

   (b) An annuity contract that provides equal or substantially equal monthly,
       quarterly, or annual payments over the life of the Depositor.

   (c) An annuity contract that provides equal or substantially equal monthly,
       quarterly, or annual payments over the joint and last survivor lives of
       the Depositor and his or her designated beneficiary.

   (d) Equal or substantially equal annual payments over a specified period that
       may not be longer than the Depositor's life expectancy.

   (e) Equal or substantially equal annual payments over a specified period that
       may not be longer than the joint life and last survivor expectancy of the
       Depositor and his or her designated beneficiary.

4. If the Depositor dies before his or her entire interest is distributed to him
   or her, the entire remaining interest will be distributed as follows:

   (a) If the Depositor dies on or after distribution of his or her interest has
       begun, distribution must continue to be made in accordance with paragraph
       3.

   (b) If the Depositor dies before distribution of his or her interest has
       begun, the entire remaining interest will, at the election of the
       Depositor or, if the Depositor has not so elected, at the election of the
       beneficiary or beneficiaries, either

       (i)  Be distributed by the December 31 of the year containing the fifth
            anniversary of the Depositor's death, or

       (ii) Be distributed in equal or substantially equal payments over the
            life or life expectancy of the designated beneficiary or
            beneficiaries starting by December 31 of the year following the year
            of the Depositor's death. If, however, the beneficiary is the
            Depositor's surviving spouse, then this distribution is not required
            to begin before December 31 of the year in which the Depositor would
            have reached age 70 1/2.

                                       2
<PAGE>
 
   (c) Except where distribution in the form of an annuity meeting the
       requirements of Section 408(b)(3) and its related regulations has
       irrevocably commenced, distributions are treated as having begun on the
       Depositor's required beginning date, even though payments may actually
       have been made before that date.

   (d) If the Depositor dies before his or her entire interest has been
       distributed and if the beneficiary is other than the surviving spouse, no
       additional cash contributions or rollover contributions may be accepted
       in the account.

5. In the case of a distribution over life expectancy in equal or substantially
   equal annual payments, to determine the minimum annual payment for each year,
   divide the Depositor's entire interest in the Custodial Account as of the
   close of business on December 31 of the preceding year by the life expectancy
   of the Depositor (or the joint life and last survivor expectancy of the
   Depositor and the Depositor's designated beneficiary, or the life expectancy
   of the designated beneficiary, whichever applies). In the case of
   distributions under paragraph 3, determine the initial life expectancy (or
   joint life and last survivor expectancy) using the attained ages of the
   Depositor and designated beneficiary as of their birthdays in the year the
   Depositor reaches age 70 1/2. In the case of a distribution in accordance
   with paragraph 4(b)(ii), determine life expectancy using the attained age of
   the designated beneficiary as of the beneficiary's birthday in the year
   distributions are required to commence.

6. The owner of two or more individual retirement accounts may use the
   "alternative method" described in Notice 88-38, 1988-1 C.B. 524, to satisfy
   the minimum distribution requirements described above. This method permits an
   individual to satisfy these requirements by taking from one individual
   retirement account the amount required to satisfy the requirement for
   another.

ARTICLE V.......................................................................

1. The Depositor agrees to provide the Custodian with information necessary for
   the Custodian to prepare any reports required under Section 408(i) and
   Regulations Sections 1.408-5 and 1.408-6.

2. The Custodian agrees to submit reports to the Internal Revenue Service and
   the Depositor prescribed by the Internal Revenue Service.

ARTICLE VI......................................................................

Notwithstanding any other articles which may be added or incorporated, the
provisions of Articles I through III and this sentence will be controlling. Any
additional articles that are not consistent with Section 408(a) and related
regulations will be invalid.

                                       3
<PAGE>
 
ARTICLE VII.....................................................................

This Agreement will be amended from time to time to comply with the provisions
of the Code and related regulations. Other amendments may be made with the
consent of the persons whose signatures appear on the Application.

ARTICLE VIII....................................................................

8.01  Definitions: In this part of this Agreement (Article VIII), the words
      "you" and "your" mean the Depositor, the words "we," "us" and "our" mean
      the Custodian and "Code" means the Internal Revenue Code.

8.02  Notices and Change of Address: Any required notice regarding this IRA will
      be considered effective when we mail it to the last address of the
      intended recipient which we have in our records. Any notice to be given to
      us will be considered effective when we actually receive it. You must
      notify us of any change of address.

8.03  Representations and Responsibilities: You represent and warrant to us that
      any information you have given or will give us with respect to this
      Agreement is complete and accurate. Further, you agree that any directions
      you give us, or action you take will be proper under this Agreement and
      that we are entitled to rely upon any such information or directions. We
      shall not be responsible for losses of any kind that may result from your
      directions to us or your actions or failures to act and you agree to
      reimburse us for any loss we may incur as a result of such directions,
      actions or failures to act. We shall not be responsible for any penalties,
      taxes, judgments or expenses you incur in connection with your IRA. We
      have no duty to determine whether your contributions or distributions
      comply with the Code, regulations, rulings or this Agreement.

8.04  Service Fees: We have the right to charge an annual service fee or other
      designated fees (for example, a transfer, rollover or termination fee) for
      maintaining your IRA. In addition, we have the right to be reimbursed for
      all reasonable expenses we incur in connection with the administration of
      your IRA. We may charge you separately for any fees or expenses or we may
      deduct the amount of the fees or expenses from the assets in your IRA at
      our discretion. We reserve the right to charge any additional fee upon 30
      days notice to you that the fee will be effective.

      Any brokerage commissions attributable to the assets in your IRA will be
      charged to your IRA. You cannot reimburse your IRA for those commissions.

8.05  Investment of Amounts in the IRA:

   a. Direction of Investment - You have exclusive responsibility for and
      control over the investment of the assets of your IRA. You shall direct
      all investment transactions, including earnings and the proceeds from
      securities sales. Your selection of investments, however, shall be limited
      to publicly traded securities, mutual funds, money market instruments and
      other investments that are obtainable by us and that we are capable of
      holding in the ordinary course of our business.

      In the absence of instructions from you or if your instructions are not in
      a form acceptable to us, we shall hold any uninvested amounts in cash and
      we shall have no responsibility to invest uninvested cash unless and until
      directed by you.

      All transactions shall be subject to any and all applicable Federal and
      State laws and regulations and the rules, regulations, customs and usages
      of any exchange, market or clearing house where the transaction is
      executed and to our policies and practices.

      After your death, your beneficiary(ies) shall have the right to direct the
      investment of your IRA assets, subject to the same conditions that applied
      to you during your lifetime under this Agreement (including, without
      limitation, Section 8.03).

   b. Our Investment Powers and Duties - We shall have no discretion to direct
      any investment in your IRA. We assume no responsibility for rendering
      investment advice with respect to your IRA, nor will we offer any opinion
      or judgment to you on matters concerning the value or suitability of any
      investment or proposed investment for your IRA. We shall exercise the
      voting rights and other shareholder rights with respect to securities in
      your IRA but only in accordance with the instructions you give to us.

   c. Delegation of Investment Responsibility - We may, but are not required to,
      permit you to delegate your investment responsibility for your IRA to
      another party acceptable to us by giving written notice of your delegation
      in a format we prescribe. We shall follow the direction of any such party
      who is properly appointed and we shall be under no duty to review or
      question, nor shall we be responsible for, any of that party's directions,
      actions or failures to act.

8.06  Beneficiaries: If you die before you receive all of the amounts in your
      IRA, payments from your IRA will be made to your beneficiaries. 

      You may designate one or more person or entity as beneficiary of your IRA.
      This designation can only

                                       5
<PAGE>
 
      be made on a form prescribed by us and it will only be effective when it
      is filed with us during your lifetime. Each beneficiary designation you
      file with us will cancel all previous ones. The consent of a beneficiary
      shall not be required for you to revoke a beneficiary designation. If you
      do not designate a beneficiary, your estate will be the beneficiary.

      If the beneficiary payment election described in Article IV, Section 4(b)
      of this Agreement is not made by December 31 of the year following the
      year of your death, the following rules apply. If the beneficiary is your
      spouse, the payment described in Article IV, Section 4(b)(ii) will be
      deemed elected (that is, payments over the life or life expectancy of your
      spouse). If the beneficiary or beneficiaries are or include anyone other
      than your surviving spouse, the payment method described in Article IV,
      Section 4(b)(i) will be deemed elected (that is the 5 year rule).

      A spouse beneficiary will retain the option to treat the deceased's IRA as
      his or her own.

8.07  Termination: Either party may terminate this Agreement at any time by
      giving written notice to the other. We can resign as Custodian at any time
      effective 30 days after we mail written notice of our resignation to you.
      Upon receipt of that notice, you must make arrangements to transfer your
      IRA to another financial organization. If you do not complete a transfer
      of your IRA within 30 days from the date we mail the notice to you, we
      have the right to transfer your IRA assets to a successor IRA custodian or
      trustee that we choose in our sole discretion or we may pay your IRA to
      you in a single sum. We shall not be liable for any actions or failures to
      act on the part of any successor custodian or trustee nor for any tax
      consequences you may incur that result from the transfer or distribution
      of your assets pursuant to this section.

      If this Agreement is terminated, we may hold back from your IRA a
      reasonable amount of money that we believe is necessary to cover any one
      or more of the following:

      . any fees, expenses or taxes chargeable against your IRA;

      . any penalties associated with the early withdrawal of any savings
        instrument or other investment in your IRA.

      If our organization is merged with another organization (or comes under
      the control of any Federal or State agency) or if our entire organization
      (or any portion which includes your IRA) is bought by another
      organization, that organization (or agency) shall automatically become the
      custodian or trustee
  
                                       6
<PAGE>
 
      of your IRA, but only if it is the type of organization authorized to
      serve as an IRA custodian or trustee.

      If we are required to comply with Section 1.408-2(e) of the Treasury
      Regulations and we fail to do so, or we are not keeping the records,
      making the returns or sending the statements as are required by forms or
      regulations, the IRS may, after notifying you, require you to substitute
      another custodian or trustee.

8.08  Amendments: We have the right to amend this Agreement at any time. Any
      amendment we make to comply with the Code and related regulations does not
      require your consent. You will be deemed to have consented to any other
      amendment unless, within 30 days from the date we mail the amendment, you
      notify us in writing that you do not consent.

8.09  Withdrawals: All requests for withdrawal shall be in writing on a form
      provided by or acceptable to us. The method of distribution must be
      specified in writing. The tax identification number of the recipient must
      be provided to us before we are obligated to make a distribution.

      Any withdrawals shall be subject to all applicable tax and other laws and
      regulations including possible early withdrawal penalties and withholding
      requirements.

8.10  Required Minimum Distributions: We reserve the right to elect whether or
      not life expectancies will be recalculated in connection with required
      minimum distributions from your IRA, provided, however, that we give you
      notice of our election. Alternatively, we may allow you to make such an
      election. 

      As described in Article IV, Section 3, of this Agreement, you may make an
      election to begin receiving payments from your IRA in a manner that
      satisfies the required minimum distribution rules no later than April 1st
      of the year following the year you reach age 70 1/2. (This is called the
      "required beginning date.") If you fail to make such an election by your
      required beginning date, we can, at our complete and sole discretion, do
      any one of the following:

      . make no payment until you give us a proper payment request;

      . pay your entire IRA to you in a single sum payment; or

      . calculate your required minimum distribution from your IRA each year
        based on your single life expectancy (not recalculated) and pay those
        distributions to you until you direct otherwise.

                                       7
<PAGE>
 
      We will not be liable for any penalties or taxes related to your failure
      to take a distribution.

8.11  Transfers From Other Plans: We can receive amounts transferred to this IRA
      from the custodian or trustee of another IRA. In addition, we can accept
      direct rollovers of eligible rollover distributions from employer plans as
      permitted by the Code. We reserve the right not to accept any transfer or
      direct rollover.

8.12  Liquidation Of Assets: We have the right to liquidate assets in your IRA
      if necessary to make distributions or to pay fees, expenses or taxes
      properly chargeable against your IRA. If you fail to direct us as to which
      assets to liquidate, we will decide in our complete and sole discretion
      and you agree not to hold us liable for any adverse consequences that
      result from our decision.

8.13  Restrictions On The Fund: Neither you nor any beneficiary may sell,
      transfer or pledge any interest in your IRA in any manner whatsoever,
      except as provided by law or this Agreement. 

      The assets in your IRA shall not be responsible for the debts, contracts
      or torts of any person entitled to distributions under this Agreement.

8.14  What Law Applies: This Agreement is subject to all applicable Federal and
      State laws and regulations. If it is necessary to apply any State law to
      interpret and administer this Agreement, the law of our domicile shall
      govern. 

      If any part of this Agreement is held to be illegal or invalid, the
      remaining parts shall not be affected. Neither your nor our failure to
      enforce at any time or for any period of time any of the provisions of
      this Agreement shall be construed as a waiver of such provisions, or your
      right or our right thereafter to enforce each and every such provision.

8.15  Arbitration Disclosures:

      .  Arbitration is final and binding on the parties.

      .  The parties are waiving their right to seek remedies in court,
         including the right to jury trial.

      .  Pre-arbitration discovery is generally more limited than and different
         from court proceedings.

      .  The arbitrators' award is not required to include factual findings or
         legal reasoning and any party's right to appeal or to seek modification
         of rulings by the arbitrators is strictly limited.

      .  The panel of arbitrators will typically include a minority of
         arbitrators who were or are affiliated with the securities industry.

     ARBITRATION--Customer agrees, and by carrying an account for customer
     broker agrees that all controversies which may arise between us prior to,
     on or subsequent to the date of the signed agreement shall be determined by
     arbitration. Any arbitration under the signed agreement shall be conducted
     pursuant to the federal arbitration act and the laws of the state of
     Illinois, before the American arbitration forum, or before the New York
     Stock Exchange, Inc. or an arbitration forum provided by any other exchange
     of which the broker is a member, the National Association of Securities
     Dealers, Inc. or any self-regulatory organization governing the broker in
     accordance and with the rules then in effect of the selected organization.
     The customer may elect one of the organizations (Forum) stated above, but
     if the customer fails to make that election, by registered letter or
     telegram addressed to the broker at the broker's main office, before the
     expiration of ten days after receipt of a written request from the broker
     to make that election, then the broker may make that election. The award of
     the arbitrators, or the majority of them shall be final, and judgment upon
     the award rendered may be entered in any court, state or federal, having

     person who has initiated in court a putative class action; or who is a
     member of a putative class who has not opted out of the class with respect
     to any claims encompassed by the putative class action until: (i) the class
     certification is denied; or (ii) the class is decertified; or (iii)
     customer is excluded from the class by the court. Such forbearance to
     enforce an agreement to arbitrate shall not constitute a waiver of any
     rights under this agreement except to the extent stated here in. By signing
     the agreement customer acknowledges that the customer has received and read
     a copy of this agreement.

PURPOSE OF FORM

NOTE: Users of the October 1992 revision of Form 5305-A are not required to use
the January 1998 revision of the form.

Form 5305-A is a model Custodial account agreement that meets the requirements
of Section 408(a) and has been automatically approved by the IRS. An individual
retirement account (IRA) is established after the form is fully executed by both
the individual (Depositor) and

                                       9
<PAGE>
 
the Custodian and must be completed no later than the due date of the
individual's income tax return for the tax year (without regard to extensions).
This account must be created in the United States for the exclusive benefit of
the Depositor or his or her Beneficiaries. 

Individuals may rely on regulations for Tax Reform Act of 1986 to the extent
specified in those regulations.

Do not file Form 5305-A with the IRS. Instead, keep it for your records. 

For more information on IRAs, including the required disclosures the Custodian
must give the Depositor, see Pub. 590, Individual Retirement Arrangements
(IRAs).

DEFINITIONS

Custodian: The Custodian must be a bank or savings and loan association, as
defined in Section 408(n), or any person who has the approval of the IRS to act
as Custodian.

Depositor: The Depositor is the person who establishes the Custodial account.

IDENTIFYING NUMBER

The Depositor's social security number will serve as the identification number
of his or her IRA. An employer identification number (EIN) is required only for
an IRA for which a return is filed to report unrelated business taxable income.
An EIN is required for a common fund created for IRAs.

IRA FOR NONWORKING SPOUSE

Form 5305-A may be used to establish the IRA Custodial account for a nonworking
spouse.

Contributions to an IRA Custodial account for a nonworking spouse must be made
to a separate IRA Custodial account established by the nonworking spouse.

REQUIREMENTS OF AN IRA

A. CASH CONTRIBUTIONS - Your contribution must be in cash, unless it is a
   rollover contribution.

B. MAXIMUM CONTRIBUTION - The total amount you may contribute to an IRA for any
   taxable year cannot exceed the lesser of $2,000 or 100 percent of your
   compensation. If you also maintain a Roth IRA, the maximum contribution to
   your Traditional IRAs (i.e., IRAs subject to Internal Revenue Code (IRC)
   Sections 408(a) or 408(b)) is reduced by any contributions you make to your
   Roth IRA. Your total annual contribution to all Traditional IRAs and Roth
   IRAs cannot exceed the lesser of $2,000 or 100 percent of your compensation.

C. NONFORFEITABILITY - Your interest in your IRA is nonforfeitable.

D. ELIGIBLE CUSTODIANS - The Custodian of your IRA must be a bank, savings and
   loan association, credit union, or a person approved by the Secretary of the
   Treasury.

E. COMMINGLING ASSETS - The assets of your IRA cannot be commingled with other
   property except in a common trust fund or common investment fund.

F. LIFE INSURANCE - No portion of your IRA may be invested in life insurance
   contracts.

G. COLLECTIBLES - You may not invest the assets of your IRA in collectibles
   (within the meaning of Internal Revenue Code (IRC) Section 408(m)). A
   collectible is defined as any work of art, rug or antique, metal or gem,
   stamp or coin, alcoholic beverage, or other tangible personal property
   specified by the Internal

                                      11
<PAGE>
 
   Revenue Service. However, specially minted United States gold and silver
   bullion coins and certain state-issued coins are permissible investments.
   Beginning January 1, 1998, platinum coins and certain gold, silver, platinum
   or palladium bullion (as described in IRC Section 408(m)(3)) are also
   permitted as IRA investments.

H. REQUIRED MINIMUM DISTRIBUTIONS - You are required to take minimum
   distributions from your IRA at certain times in accordance with Proposed
   Treasury Regulations Section 1.408-8. Below is a summary of the IRA
   distribution rules.

   1. You are required to take a minimum distribution from your IRA for the year
      in which you reach age 70 1/2 and for each year thereafter. You must take
      your first payout by your required beginning date, April 1 of the year
      following the year you attain age 70 1/2. The minimum distribution for any
      taxable year is equal to the amount obtained by dividing the account
      balance at the end of the prior year (less any required distribution taken
      between January 1 and April 1 of the year following the year you attain
      age 70 1/2) by the joint life expectancy of you and your designated
      beneficiary. If you have not designated a beneficiary for your IRA by your
      required beginning date, your single life expectancy will be used.

   2. Your single or joint life expectancy is determined by using the IRS unisex
      life expectancy tables. You can find these tables in Treasury Regulations
      Section 1.72-9.

      We will allow you to elect whether or not to recalculate your life
      expectancies. If you do not make an election, your life expentancies will
      not be recalculated.

      You may choose (within the limits set forth in the distribution rules and
      our life expectancy recalculation policy) how you want your required
      minimum distributions structured. You must make your payment elections no
      later than April 1 following your 70 1/2 year. If you do not make an
      election by that date, we may do any one of the following:

      (a) make no payment until you give us a proper payout request,

      (b) pay your entire IRA to you in a single sum payment, or

      (c) determine your required minimum distribution each year based on your
          single life expectancy (not recalculated) and pay those distributions
          to you until you direct otherwise.

   3. If you name someone other than your spouse as your beneficiary, and your
      beneficiary is more 

                                      12
<PAGE>
 
      than 10 years younger than you, your required minimum distributions must
      satisfy the Minimum Distribution Incidental Benefit (MDIB) rule. The MDIB
      rule generally requires that your required minimum distributions be
      calculated as if your beneficiary were exactly 10 years younger than you.

   4. If you die,

      (a) on or after your required beginning date, distributions must be made
          to your beneficiary or beneficiaries at least as rapidly as under the
          method being used to determine minimum distributions as of the date of
          your death.

      (b) before your required beginning date, the entire amount remaining in
          your account will, at the election of your beneficiary or
          beneficiaries, either

          (i)  be distributed by December 31 of the year containing the fifth
               anniversary of your death, or

          (ii) be distributed in equal or substantially equal payments over the
               life or life expectancy of your designated beneficiary or
               beneficiaries.

          Your beneficiary or beneficiaries must elect either option (i) or (ii)
          by December 31 of the year following the year of your death. If no
          election is made, distribution will be made in accordance with (ii) if
          the beneficiary is your surviving spouse, and in accordance with (i)
          if your beneficiary is not your surviving spouse. In the case of
          distributions under (ii), distributions must commence by December 31
          of the year following the year of your death. If your spouse is the
          beneficiary, distributions need not commence until December 31 of the
          year you would have attained age 70 1/2, if later.

INCOME TAX CONSEQUENCES OF ESTABLISHING AN IRA

A. IRA DEDUCTIBILITY - If you have not yet reached the year in which you attain
   age 70 1/2 and have earned income from services rendered, you may make an IRA
   contribution of the lesser of 100 percent of compensation or $2,000. However,
   the amount of the contribution for which you may take a tax deduction will
   depend upon whether you (or, in some cases, your spouse) are an active
   participant in an employer-maintained retirement plan. If you are not an
   active participant, your IRA contribution will be totally deductible. If you
   are an active participant, the deductibility of your contribution will depend
   on your modified adjusted gross income (MAGI) for the tax year for which the
   contribution was made. Modified adjusted gross income (MAGI) is determined

                                      13
<PAGE>
 
   on your tax return using your adjusted gross income but disregarding any
   deductible IRA contribution.

   DEFINITION OF ACTIVE PARTICIPANT - Generally, you will be an active
   participant if you are covered by one or more of the following employer-
   maintained retirement plans:

   1. a qualified pension, profit sharing, 401(k), or stock bonus plan;

   2. a qualified annuity plan of an employer;

   3. a simplified employee pension (SEP) plan;

   4. a retirement plan established by the Federal government, a State, or a
      political subdivision (except certain unfunded deferred compensation plans
      under IRC Section 457);

   5. a tax sheltered annuity for employees of certain tax-exempt organizations
      or public schools;

   6. a plan meeting the requirements of IRC Section 501(c)(18);

   7. a qualified plan for self-employed individuals (H.R. 10 or Keogh Plan);
      and

   8. a SIMPLE IRA plan or a SIMPLE 401(k) plan.

   If you do not know whether your employer maintains one of these plans or
   whether you are an active participant in it, check with your employer and
   your tax advisor. Also, the Form W-2 (Wage and Tax Statement) that you
   receive at the end of the year from your employer will indicate whether you
   are an active participant.

   If you are an active participant and are single, the deductible amount of
   your contribution is determined as follows: (1) take the Phase-out Maximum
   for the applicable year (specified below) and subtract your MAGI, (2)
   multiply the difference by .2. For example, if your 1998 MAGI is $35,000,
   your maximum deductible contribution is $1,000 (the 1998 Phase-out Maximum of
   $40,000 minus your MAGI of $35,000, multiplied by .2). You must round the
   resulting number to the next highest $10 if the number is not a multiple of
   10.

   If you are an active participant, are married and you file a joint tax
   return, the deductible amount of your contributions is determined as follows:
   (1) take the Phase-out Maximum for the applicable year (specified below) and
   subtract your MAGI, (2) multiply the difference by .2. (Multiply the
   difference between the Phase-out Maximum and your MAGI by .1 beginning in
   2007.) For example, if your MAGI in 1998 is $55,000, your maximum deductible
   contribution is $1,000: [($60,000 minus $55,000) multiplied by .2]. You must
   round the resulting number to the next highest $10 if the number is not a
   multiple of 10.

- ----------------------------------------------------------------------
</TABLE>

   If you are married filing jointly and are not an active participant in an
   employer-maintained retirement plan, but are married to someone who is an
   active participant, your maximum deductible contribution is determined by
   taking $160,000 minus your MAGI and multiplying the result by .2 (subject to
   the maximum combined annual contribution limit for Traditional and Roth IRAs
   of the lesser of $2,000 or 100 percent of earned income).

B. TAX-DEFERRED EARNINGS - The investment earnings of your IRA are not subject
   to federal income tax until distributions are made (or, in certain instances,
   when distributions are deemed to be made).

C. NONDEDUCTIBLE CONTRIBUTIONS - You may make nondeductible contributions to
   your IRA to the extent that deductible contributions are not allowed. The sum
   of your deductible and nondeductible IRA contributions cannot exceed your
   contribution limit (the lesser of $2,000 or 100 percent of compensation). You
   may elect to treat deductible IRA contributions as nondeductible
   contributions.

   If you make nondeductible contributions for a particular tax year, you must
   report the amount of the nondeductible contribution on your federal income
   tax return (using IRS Form 8606).

   If you overstate the amount of designated nondeductible contributions for any
   taxable year, you are subject to a $100 penalty unless reasonable cause for
   the overstatement can be shown. Failure to file any form required by the IRS
   to report nondeductible contributions (e.g., IRS Form 8606) will result in a
   $50 per failure penalty.

D. TAXATION OF DISTRIBUTIONS - The taxation of IRA distributions depends on
   whether or not you have ever made nondeductible IRA contributions. If you
   have only made deductible contributions, any IRA distribution will be fully
   included in income.

                                      15
<PAGE>
 
   If you have ever made nondeductible contributions to any IRA, the following
   formula must be used to determine the amount of any IRA distribution excluded
   from income:

   (Aggregate Nondeductible Contributions)

          x (Amount Withdrawn)    =  Amount Excluded From Income
         ---------------------                                  
         Aggregate IRA Balance

   NOTE: Aggregate nondeductible contributions include all nondeductible
   contributions made by you through the end of the year of the distribution
   (which have not previously been withdrawn and excluded from income). Also
   note that aggregate IRA balance includes the total balance of all of your
   IRAs as of the end of the year of distribution and any distributions
   occurring during the year.

E. ROLLOVERS - Your IRA may be rolled over to an IRA of yours, or may receive
   rollover contributions, provided that all of the applicable rollover rules
   are followed. Rollover is a term used to describe a tax-free movement of cash
   or other property to your IRA from any of your IRAs, or from your employer's
   Qualified Retirement Plan or Tax Sheltered Annuity. SIMPLE IRA funds may not
   be rolled to your IRA during the first two years you participate in your
   employer's SIMPLE IRA plan. The rollover rules are generally summarized
   below. These transactions are often complex. If you have any questions
   regarding a rollover, please see a competent tax advisor.

   1. IRA to IRA Rollovers - Funds distributed from your IRA may be rolled over
      to an IRA of yours if the requirements of IRC Section 408(d)(3) are met. A
      proper IRA to IRA rollover is completed if all or part of the distribution
      is rolled over not later than 60 days after the distribution is received.
      You may not have completed another IRA to IRA rollover from the
      distributing IRA during the 12 months preceding the date you receive the
      distribution. Further, you may roll the same dollars or assets only once
      every 12 months.

   2. Qualified Plan (or Tax-Sheltered Annuity) to IRA Rollovers - Effective for
      qualified plan distributions received after January 1, 1993, you may roll
      over, directly or indirectly, any eligible rollover distribution. An
      eligible rollover distribution is defined generally as any distribution
      from a qualified plan (other than distributions to nonspouse
      beneficiaries) unless it is part of certain series of substantially equal
      periodic payments, after-tax dollars or a required minimum distribution.

      To qualify as a rollover, your eligible rollover distribution must be
      rolled over to your IRA not later than 60 days after you receive it.

                                      16
<PAGE>
 
      If you elect to receive your rollover distribution prior to placing it in
      an IRA, thereby conducting an indirect rollover, your plan administrator
      will generally be required to withhold 20 percent of your distribution as
      a prepayment of income taxes. When completing the rollover, you may make
      up the amount withheld, out of pocket, and roll over the full amount
      distributed from your qualified plan balance, if you so choose. To qualify
      as a rollover, your eligible rollover distribution must be rolled over to
      your IRA not later than 60 days after you receive it. Alternatively, you
      may claim the withheld amount as income and pay the applicable income tax
      and, if you are under age 59 1/2, the 10 percent early distribution
      penalty (unless an exception to the penalty applies).

      As an alternative to the indirect rollover, your employer generally must
      give you the option of directly rolling your qualified plan balance over
      to an IRA. If you elect the direct rollover option, your eligible rollover
      distribution will be paid directly to the IRA (or other qualified plan)
      that you designate. The 20 percent withholding requirements do not apply
      to direct rollovers.

      If you place your rollover contribution in a separate (i.e., conduit) IRA
      plan which holds just those dollars, you preserve the right to later roll
      the money originating from the qualified plan into another qualified plan.

   3. Traditional IRA to Roth IRA Rollovers - If your adjusted gross income is
      not more than $100,000, you are eligible to roll over (or convert) all or
      any portion of your existing Traditional IRA(s) into your Roth IRA(s). The
      amount of the rollover from your Traditional IRA to your Roth IRA shall be
      treated as a distribution for income tax purposes and is includible in
      your gross income (except for any nondeductible contributions). Although
      the rollover amount is generally included in income, the 10 percent early
      distribution penalty shall not apply to rollovers or conversions from a
      Traditional IRA to a Roth IRA, regardless of whether you qualify for any
      exceptions to the 10 percent penalty.

      If you roll over assets from your Traditional IRA to your Roth IRA prior
      to January 1, 1999, you may spread the amount of the distributions which
      must be included in your gross income ratably over a four year period
      beginning with the year in which the payment or distribution is made.

   4. Written Election - At the time you make a proper rollover to an IRA, you
      must designate to the Custodian, in writing, your election to treat that
      con-

                                      17
<PAGE>
 
     tribution as a rollover. Once made, the rollover election is irrevocable.

F. CARRYBACK CONTRIBUTIONS - A contribution is deemed to have been made on the
   last day of the preceding taxable year if you make a contribution by the
   deadline for filing your income tax return (not including extensions), and
   you designate that contribution as a contribution for the preceding taxable
   year. For example, if you are a calendar year taxpayer and you make your IRA
   contribution on or before April 15, your contribution is considered to have
   been made for the previous tax year if you designated it as such.

LIMITATIONS AND RESTRICTIONS

A. SEP PLANS - Under a Simplified Employee Pension (SEP) Plan that meets the
   requirements of IRC Section 408(k), your employer may make contributions to
   your IRA. Your employer is required to provide you with information which
   describes the terms of your employer's SEP Plan.

B. SPOUSAL IRA - If you are married, you may make payments to an IRA established
   for the benefit of your spouse. Your spouse must not have attained age 70 1/2
   in that year, or any prior year, even if you are age 70 1/2 or older. You
   must file a joint tax return for the year for which the contribution is made.

   The amount you may contribute to your IRA and your spouse's IRA is the lesser
   of $4,000 or 100 percent of your combined compensation.  However, you may not
   contribute more than $2,000 to any one IRA.

C. DEDUCTION OF ROLLOVERS AND TRANSFERS - A deduction is not allowed for
   rollover or transfer contributions.

D. ESTATE TAX EXCLUSION - The $100,000 federal estate tax exclusion previously
   available has been repealed for individuals dying after 12/31/84. No
   exclusion will be allowed for individuals dying after that date. Transfers of
   your IRA assets to a named beneficiary made during your life and at your
   request or because of your failure to instruct otherwise, may be subject to
   federal gift tax under IRC Section 2501 if made after October 22, 1986.

E. SPECIAL TAX TREATMENT - Capital gains treatment and the favorable five or ten
   year forward averaging tax authorized by IRC Section 402 do not apply to IRA
   distributions.

F. INCOME TAX TREATMENT - Any withdrawal from your IRA, except a direct
   transfer, is subject to federal income tax withholding. You may, however,
   elect not to have withholding apply to your IRA withdrawal. If withholding is
   applied to your with-

                                      18
<PAGE>
 
   drawal, not less than 10 percent of the amount withdrawn must be withheld.

G. PROHIBITED TRANSACTIONS - If you or your beneficiary engage in a prohibited
   transaction with your IRA, as described in IRC Section 4975, your IRA will
   lose its tax-exempt status and you must include the value of your account in
   your gross income for that taxable year.

H. PLEDGING - If you pledge any portion of your IRA as collateral for a loan,
   the amount so pledged will be treated as a distribution and will be included
   in your gross income for that year.

FEDERAL TAX PENALTIES

A. EARLY DISTRIBUTION PENALTY - If you are under age 59 1/2 and receive an IRA
   distribution, an additional tax of 10 percent will apply, unless made on
   account of death, disability, a qualifying rollover, a direct transfer, the
   timely withdrawal of an excess contribution; or if the distribution is part
   of a series of substantially equal periodic payments (at least annual
   payments) made over your life expectancy or the joint life expectancy of you
   and your beneficiary. Payments made to pay medical expenses which exceed 7.5
   percent of your adjusted gross income and distributions to pay for health
   insurance by an individual who has separated from employment and who has
   received unemployment compensation under a federal or state program for at
   least 12 weeks are also exempt from the 10 percent tax. Beginning January 1,
   1998, payments to cover certain qualified higher education expenses and
   distributions for first-home purchases (up to life-time maximum of $10,000)
   are exempt from the 10 percent tax. This additional tax will apply only to
   the portion of a distribution which is includible in your income.

B. EXCESS CONTRIBUTION PENALTY - An excise tax of 6 percent is imposed upon any
   excess contribution you make to your IRA. This tax will apply each year in
   which an excess remains in your IRA. An excess contribution is any
   contribution amount which exceeds your contribution limit, excluding rollover
   and direct transfer amounts. Your contribution limit is the lesser of $2,000
   or 100 percent of your compensation for the taxable year.

C. EXCESS ACCUMULATION PENALTY - One of the requirements listed above is that
   you must take a minimum distribution for the year you attain age 70 1/2 and
   for each year thereafter and that your designated beneficiary(ies) is
   required to take certain minimum distributions after your death. An
   additional tax of 50 percent is imposed on the amount of the required minimum
   distribution which should have been taken

                                      19
<PAGE>
 
   but was not. This tax is referred to as an excess accumulation penalty tax.

D. EXCESS DISTRIBUTION PENALTY - Prior to 1997, you would have been taxed an
   additional 15 percent on any amount received and included in income during a
   calendar year from qualified retirement plans, tax sheltered annuities and
   IRAs which exceeded $112,500 (indexed each year for the cost of living).
   Certain exceptions applied. If you received an excess distribution as
   described above, your tax advisor could determine if these exceptions applied
   to you. This tax is referred to as an excess distribution penalty. However,
   this tax is repealed effective for all payouts received after December 31,
   1996, as a result of the Taxpayer Relief Act of 1997.

E. EXCESS RETIREMENT ACCUMULATION PENALTY - In the past, your estate would have
   paid additional federal estate tax if you died with an excess retirement
   accumulation. An excess retirement accumulation existed if, at the time of
   your death, the value of all your interests in qualified plans, tax-sheltered
   annuities and IRAs exceeded the present value of an annuity with annual
   payments of $112,500 (indexed each year for the cost of living), payable over
   your life expectancy immediately before your death. This tax was referred to
   as an excess retirement accumulation tax penalty. However, this tax is
   repealed for estates of decedents dying after December 31, 1996, as a result
   of the Taxpayer Relief Act of 1997.

F. PENALTY REPORTING - You must file Form 5329 with the Internal Revenue Service
   to report and remit any penalties or excise taxes.

ARBITRATION

By signing the agreement, you agree that any controversy arising out of or
relating to your Account, any transaction made under your Account, or the
performance or breach of the Agreement shall be settled by arbitration as
described in Article 8.15 of the Custodial Agreement and paragraph twenty (20)
of the IRA account application.

OTHER

A. IRS PLAN APPROVAL - The Agreement used to establish this IRA has been
   approved by the Internal Revenue Service. The Internal Revenue Service
   approval is a determination only as to form. It is not an endorsement of the
   plan in operation or of the investments offered.

B. ADDITIONAL INFORMATION - You may obtain further information on IRAs from your
   District Office of the Internal Revenue Service. In particular, you may wish
   to obtain IRS Publication 590, Individual Retirement Arrangements.

                 ROTH INDIVIDUAL RETIREMENT CUSTODIAL ACCOUNT

Form 5305-RA Under Section 408A of the Internal Revenue Code FORM (REV. JAN.
1998)

The Depositor whose name appears on the Application is establishing a Roth
Individual Retirement Account (Roth IRA) under section 408A to provide for his
or her retirement and for the support of his or her beneficiaries after death.

The Custodian named on the Application has given the Depositor the disclosure
statement required under Regulations section 1.408-6.

The Depositor has assigned the Custodial account sum indicated on the
Application.

The Depositor and the Custodian make the following agreement:

ARTICLE I.......................................................................

1. If this Roth IRA is not designated as a Roth Conversion IRA, then, except in
   the case of a rollover contribution described in section 408A(e), the
   Custodian will accept only cash contributions and only up to a maximum amount
   of $2,000 for any tax year of the Depositor.

2. If this Roth IRA is designated as a Roth Conversion IRA, no contributions
   other than IRA Conversion Contributions made during the same tax year will be
   accepted.

ARTICLE II......................................................................

The $2,000 limit described in Article I is gradually reduced to $0 between
certain levels of adjusted gross income (AGI). For a single depositor, the
$2,000 annual contribution is phased out between AGI of $95,000 and $110,000;
for a married depositor who files jointly, between AGI of $150,000 and $160,000;
and for a married depositor who files separately, between $0 and $10,000. In the
case of a conversion, the Custodian will not accept IRA Conversion Contributions
in a tax year if the Depositor's AGI for that tax year exceeds $100,000 or if
the Depositor is married and files a separate return. Adjusted gross income is
defined in section 408A(c)(3) and does not include IRA Conversion Contributions.

ARTICLE III.....................................................................

The Depositor's interest in the balance in the Custodial account is
nonforfeitable.

ARTICLE IV......................................................................

1. No part of the Custodial funds may be invested in life insurance contracts,
   nor may the assets of the Custodial account be commingled with other property
   except in a common trust fund or common investment fund (within the meaning
   of section 408(a)(5)).

2. No part of the Custodial funds may be invested in collectibles (within the
   meaning of section 408(m)) except as otherwise permitted by section
   408(m)(3), which provides an exception for certain gold, silver, and platinum
   coins, coins issued under the laws of any state, and certain bullion.

ARTICLE V.......................................................................

1. If the Depositor dies before his or her entire interest is distributed to him
   or her and the Depositor's surviving spouse is not the sole beneficiary, the
   entire remaining interest will, at the election of the Depositor or, if the
   Depositor has not so elected, at the election of the beneficiary or
   beneficiaries, either:

                                       1
<PAGE>
 

   (a) Be distributed by December 31 of the year containing the fifth
       anniversary of the Depositor's death, or

   (b) Be distributed over the life expectancy of the designated beneficiary
       starting no later than December 31 of the year following the year of the
       Depositor's death.

   If distributions do not begin by the date described in (b), distribution
   method (a) will apply.

2. In the case of distribution method 1.(b) above, to determine the minimum
   annual payment for each year, divide the Depositor's entire interest in the
   Custodial account as of the close of business on December 31 of the preceding
   year by the life expectancy of the designated beneficiary using the attained
   age of the designated beneficiary as of the beneficiary's birthday in the
   year distributions are required to commence and subtract 1 for each
   subsequent year.

3. If the Depositor's spouse is the sole beneficiary on the Depositor's date of
   death, such spouse will then be treated as the Depositor.

ARTICLE VI......................................................................

1. The Depositor agrees to provide the Custodian with information necessary for
   the Custodian to prepare any reports required under sections 408(i) and
   408A(d)(3)(E), Regulations sections 1.408-5 and 1.408-6, and under guidance
   published by the Internal Revenue Service.

2. The Custodian agrees to submit reports to the Internal Revenue Service and
   the Depositor as prescribed by the Internal Revenue Service.

ARTICLE VII.....................................................................

Notwithstanding any other articles which may be added or incorporated, the
provisions of Articles I through IV and this sentence will be controlling. Any
additional articles that are not consistent with section 408A, the related
regulations, and other published guidance will be invalid.

ARTICLE VIII....................................................................

This agreement will be amended from time to time to comply with the provisions
of the Code, related regulations, and other published guidance. Other amendments
may be made with the consent of the persons whose signatures appear on the
Application.

ARTICLE IX......................................................................

9.01 Definitions: In this part of this Agreement (Article IX), the words "you"
     and "your" mean the Depositor and the words "we," "us" and "our" mean the
     Custodian and "Code" means the Internal Revenue Code.

9.02 Notices And Change Of Address: Any required notice regarding this Roth IRA
     will be considered effective when we mail it to the last address of the
     intended recipient which we have in our records. Any notice to be given to
     us will be considered effective when we actually receive it. You must
     notify us of any change of address.

9.03 Representations And Responsibilities: You represent and warrant to us that
     any information you have given or will give us with respect to this
     Agreement is complete and accurate. Further, you agree that any directions
     you give us, or action you take will be proper under this Agreement and
     that we are entitled to rely upon any such information or directions. We
     shall not be responsible for losses of any kind that may result from your
     directions to us or your actions or failures to act and you

                                       2
 
<PAGE>
 
     agree to reimburse us for any loss we may incur as a result of such
     directions, actions or failures to act. We shall not be responsible for any
     penalties, taxes, judgments or expenses you incur in connection with your
     Roth IRA. We have no duty to determine whether your contributions or
     distributions comply with the Code, regulations, rulings or this Agreement.

9.04 Service Fees: We have the right to charge an annual service fee or other
     designated fees (for example, a transfer, rollover or termination fee) for
     maintaining your Roth IRA. In addition, we have the right to be reimbursed
     for all reasonable expenses we incur in connection with the administration
     of your Roth IRA. We may charge you separately for any fees or expenses or
     we may deduct the amount of the fees or expenses from the assets in your
     Roth IRA at our discretion. We reserve the right to charge any additional
     fee upon 30 days notice to you that the fee will be effective. 

     Any brokerage commissions attributable to the assets in your Roth IRA will
     be charged to your Roth IRA. You cannot reimburse your Roth IRA for those
     commissions.

9.05 Investment Of Amounts In The Roth IRA:

     (a) Direction of Investment - You have exclusive responsibility for and
         control over the investment of the assets of your Roth IRA. You shall
         direct all investment transactions, including earnings and the proceeds
         from securities sales. Your selection of investments, however, shall be
         limited to publicly traded securities, mutual funds, money market
         instruments and other investments that are obtainable by us and that we
         are capable of holding in the ordinary course of our business. Selling
         short, and/or executing purchases in an amount which is greater than
         the available cash are each prohibited transactions.

         In the absence of instructions from you or if your instructions are not
         in a form acceptable to us, we shall hold any uninvested amounts in
         cash and we shall have no responsibility to invest invested cash unless
         and until directed by you.

         All transactions shall be subject to any and all applicable Federal and
         State laws and regulations and the rules, regulations, customs and
         usages of any exchange, market or clearing house where the transaction
         is executed and to our policies and practices.

         After your death, your beneficiary(ies) shall be subject to the same
         conditions that applied to you during your lifetime under this
         Agreement (including, without limitation, section 9.03).

     (b) Our Investment Powers and Duties - We shall have no discretion to
         direct any investment in your Roth IRA. We assume no responsibility for
         rendering investment advice with respect to your Roth IRA. We shall
         exercise the voting rights and other shareholder rights with respect to
         securities in your Roth IRA but only in accordance with the
         instructions you give to us.

     (c) Delegation of Investment Responsibility - We may, but are not required
         to, permit you to delegate your investment responsibility for your Roth
         IRA to another party acceptable to us by giving written notice of your
         delegation in a format we prescribe. We shall follow the direction of
         any such party who is properly appointed and we shall be under no duty

                                       3
<PAGE>
 
     to review or question, nor shall we be responsible for, any of that party's
     directions, actions or failures to act.

9.06 Beneficiaries: If you die before you receive all of the amounts in your
     Roth IRA, payments from your Roth IRA will be made to your beneficiaries.

     You may designate one or more persons or entities as beneficiary of your
     Roth IRA. This designation can only be made on a form prescribed by us and
     it will only be effective when it is filed with us during your lifetime.
     Each beneficiary designation you file with us will cancel all previous
     ones. The consent of a beneficiary shall not be required for you to revoke
     a beneficiary designation. If you do not designate a beneficiary, your
     estate will be the beneficiary.

     If your surviving spouse is your sole beneficiary, your spouse will be
     deemed to have treated your Roth IRA as his or her own Roth IRA and will
     not be subject to the required minimum distribution rules. If the
     beneficiary or beneficiaries include anyone other than your surviving
     spouse, distributions must commence in accordance with Article V. If the
     beneficiary payment election described in Article V is not made by December
     31 of the year following the year of your death, the payment method
     described as the 5 year rule will be deemed elected.

9.07 Termination: Either party may terminate this Agreement at any time by
     giving written notice to the other. We can resign as Custodian at any time
     effective 30 days after we mail written notice of our resignation to you.
     Upon receipt of that notice, you must make arrangements to transfer your
     Roth IRA to another financial organization. If you do not complete a
     transfer of your Roth IRA within 30 days from the date we mail the notice
     to you, we have the right to transfer your Roth IRA assets to a successor
     Roth IRA trustee or custodian that we choose in our sole discretion or we
     may pay your Roth IRA to you in a single sum. We shall not be liable for
     any actions or failures to act on the part of any successor trustee or
     custodian nor for any tax consequences you may incur that result from the
     transfer or distribution of your assets pursuant to this section.

     If this Agreement is terminated, we may hold back from your Roth IRA a
     reasonable amount of money that we believe is necessary to cover any one or
     more of the following:

       * any fees, expenses or taxes chargeable against your Roth IRA;

       * any penalties associated with the early withdrawal of any savings
         instrument or other investment in your Roth IRA.

     If our organization is merged with another organization (or comes under the
     control of any Federal or State agency) or if our entire organization (or
     any portion which includes your Roth IRA) is bought by another
     organization, that organization (or agency) shall automatically become the
     trustee or custodian of your Roth IRA, but only if it is the type of
     organization authorized to serve as a Roth IRA trustee or custodian.

     If we are required to comply with section 1.408-2(e) of the Treasury
     Regulations and we fail to do so, or we are not keeping the records, making
     the returns or sending the statements as are required by forms or
     regulations, the IRS

                                       4

     may, after notifying you, require you to substitute another trustee or
     custodian.

9.08 Amendments: We have the right to amend this Agreement at any time. Any
     amendment we make to comply with the Code and related regulations does not
     require your consent. You will be deemed to have consented to any other
     amendment unless, within 30 days from the date we mail the amendment, you
     notify us in writing that you do not consent.

9.09 Withdrawals: All requests for withdrawal shall be in writing on a form
     provided by or acceptable to us. The method of distribution must be
     specified in writing. The tax identification number of the recipient must
     be provided to us before we are obligated to make a distribution. Any
     withdrawals shall be subject to all applicable tax and other laws and
     regulations including possible early withdrawal penalties and withholding
     requirements.

     You are not required to take a distribution from your Roth IRA at age 70
     1/2. At your death, however, your beneficiaries must begin taking
     distributions in accordance with Article V and section 9.06 of this
     Agreement. We will make no payouts to you from your Roth IRA until you
     provide us with a written request for a distribution on a form provided by
     or approved by us.

9.10 Transfers From Other Plans: We can receive amounts transferred or rolled
     over to this Roth IRA from the trustee or custodian of another Roth IRA as
     permitted by statute or applicable regulations.

     However, if this Custodial account is designated as a Roth Conversion IRA,
     no contributions other than IRA Conversion Contributions made during the
     same tax year will be accepted.

9.11 Liquidation Of Assets: We have the right to liquidate assets in your Roth
     IRA if necessary to make distributions or to pay fees, expenses or taxes
     properly chargeable against your Roth IRA. If you fail to direct us as to
     which assets to liquidate, we will decide in our complete and sole
     discretion and you agree not to hold us liable for any adverse consequences
     that result from our decision.

9.12 Restrictions On The Fund: Neither you nor any beneficiary may sell,
     transfer or pledge any interest in your Roth IRA in any manner whatsoever,
     except as provided by law or this Agreement.

     The assets in your Roth IRA shall not be responsible for the debts,
     contracts or torts of any person entitled to distributions under this
     Agreement.

9.13 What Law Applies: This Agreement is subject to all applicable Federal and
     State laws and regulations. If it is necessary to apply any State law to
     interpret and administer this Agreement, the law of our domicile shall
     govern.

     If any part of this Agreement is held to be illegal or invalid, the
     remaining parts shall not be affected. Neither your nor our failure to
     enforce at any time or for any period of time any of the provisions of this
     Agreement shall be construed as a waiver of such provisions, or your right
     or our right thereafter to enforce each and every such provision.

9.14 Arbitration Disclosures:

     *  Arbitration is final and binding on the parties.

                                       5
<PAGE>
 
     *  The parties are waiving their right to seek remedies in court, including
        the right to jury trial.

     *  Pre-arbitration discovery is generally more limited than and different
        from court proceedings.

     *  The arbitrators' award is not required to include factual findings or
        legal reasoning and any party's right to appeal or to seek modification
        of rulings by the arbitrators is strictly limited.

     *  The panel of arbitrators will typically include a minority of
        arbitrators who were or are affiliated with the securities industry.

     ARBITRATION - Customer agrees, and by carrying an account for customer,
     broker agrees, that all controversies which may arise between us prior to,
     on or subsequent to the date of the signed agreement shall be determined by
     arbitration. Any arbitration under the signed agreement shall be conducted
     pursuant to the federal arbitration act and the laws of the state of
     Illinois, before the American arbitration forum, or before the New York
     Stock Exchange, Inc. or an arbitration forum provided by any other exchange
     of which the broker is a member, the National Association of Securities
     Dealers, Inc. or any self-regulatory organization governing the broker in
     accordance and with the rules then in effect of the selected organization.
     The customer may elect one of the organizations (Forum) stated above, but
     if the customer fails to make that election, by registered letter or
     telegram addressed to the broker's main office, before the expiration of
     ten days after receipt of a written request from the broker to make that
     election, then the broker may make that election. The award of the
     arbitrators or the majority of them shall be final, and judgement upon the
     award rendered may be entered in any court, state or federal, having
     jurisdiction.

     No person shall bring a putative or certified class action to arbitration,
     nor seek to enforce any pre-dispute arbitration agreement against any
     person who has initiated in court a putative class action; or who is a
     member of a putative class who has not opted out of the class with respect
     to any claims encompassed by the putative class action until: (i) the class
     certification is denied; or (ii) the class is decertified; or (iii)
     customer is excluded from the class by the court. Such forbearance to
     enforce an agreement to arbitrate shall not constitute a waiver of any
     rights under this agreement except to the extent stated here in. By signing
     the agreement, customer acknowledges that the customer has received and
     read a copy of this agreement.

PURPOSE OF FORM

Form 5305-RA is a model Custodial account agreement that meets the requirements
of section 408A and has been automatically approved by the IRS. A Roth
individual retirement account (Roth IRA) is established after the form is fully
executed by both the individual (Depositor) and the Custodian and must be
completed no later than the due date of the individual's income tax return for
the tax year (without regard to extensions). This account must be created in the
United States for the exclusive benefit of the Depositor or his or her
beneficiaries.

Do not file Form 5305-RA with the IRS. Instead, keep it for your records.

<PAGE>
 
Unlike contributions to Traditional individual retirement arrangements,
contributions to a Roth IRA are not deductible from the Depositor's gross
income; and distributions after 5 years that are made when the Depositor is 59
1/2 years of age or older or on account of death, disability, or the purchase of
a home by a first-time homebuyer (limited to $10,000), are not includible in
gross income. For more information on Roth IRAs, including the required
disclosure the Depositor can get from the Custodian, see Pub. 590, Individual
Retirement Arrangements (IRAs).

This Roth IRA can be used by a Depositor to hold: (1) IRA Conversion
Contributions, amounts rolled over or transferred from another Roth IRA, and
annual cash contributions of up to $2,000 from the Depositor; or (2) if
designated as a Roth Conversion IRA (by checking the box on the Application),
only IRA Conversion Contributions for the same tax year.

To simplify the identification of funds distributed from Roth IRAs, Depositors
are encouraged to maintain IRA Conversion Contributions for each tax year in a
separate Roth IRA.

DEFINITIONS

Roth Conversion IRA: A Roth Conversion IRA is a Roth IRA that accepts only IRA
Conversion Contributions made during the same tax year.

IRA Conversion Contributions: IRA Conversion Contributions are amounts rolled
over, transferred, or considered transferred from a nonRoth IRA to a Roth IRA. A
nonRoth IRA is an individual retirement account or annuity described in section
408(a) or 408(b), other than a Roth IRA.

Custodian: The Custodian must be a bank or savings and loan association, as
defined in section 408(n), or any person who has the approval of the IRS to act
as Custodian.

Depositor: The Depositor is the person who establishes the Custodial account.

                             ---------------------
                             SPECIFIC INSTRUCTIONS

Article I: The Depositor may be subject to a 6-percent tax on excess
contributions if (1) contributions to other individual retirement arrangements
of the Depositor have been made for the same tax year, (2) the Depositor's
adjusted gross income exceeds the applicable limits in Article II for the tax
year, or (3) the Depositor's and spouse's compensation does not exceed the
amount contributed for them for the tax year. The Depositor should see the
Disclosure Statement or Pub. 590 for more information.

Article IX: Article IX and any that follow it may incorporate additional
provisions that are agreed to by the Depositor and Custodian to complete the
agreement. They may include, for example, definitions, investment powers, voting
rights, exculpatory provisions, amendment and termination, removal of the
Custodian, Custodian's fees, state law requirements, beginning date of
distributions, accepting only cash, treatment of excess contributions,
prohibited transactions with the Depositor, etc. Use additional pages if
necessary and attach them to the application.

                             DISCLOSURE STATEMENT
                                        
RIGHT TO REVOKE YOUR ROTH IRA

If you receive this Disclosure Statement at the time you establish your Roth
IRA, you have the right to revoke your Roth IRA within seven (7) days of its
establishment. If revoked, you are entitled to a full return of the contribution
you made to your Roth IRA. The amount returned to you would not include an
adjustment for such items as sales commissions, administrative expenses, or
fluctuation in market value. You may make this revocation only by mailing or
delivering a written notice to the Custodian at the address listed on the
Application.

If you send your notice by first-class mail, your revocation will be deemed
mailed as of the date of the postmark.

If you have any questions about the procedure for revoking your Roth IRA, please
call the Custodian at the telephone number listed on the Application.

REQUIREMENTS OF A ROTH IRA

A. CASH CONTRIBUTIONS - Your contribution must be in cash, unless it is a
   qualified rollover contribution.

B. MAXIMUM CONTRIBUTION - The total amount you may contribute to a Roth IRA for
   any taxable year cannot exceed the lesser of $2,000 or 100 percent of your
   compensation. If you also maintain a Traditional IRA (i.e., an IRA subject to
   the limits of Internal Revenue Code (IRC) Sec. 408(a) or 408(b)) the maximum
   contribution to your Roth IRA is reduced by any contributions you make to
   your Traditional IRA. Your total annual contribution to all Traditional IRAs
   and Roth IRAs cannot exceed the lesser of $2,000 or 100 percent of your
   compensation.

   Your Roth IRA contribution is further limited if your adjusted gross income
   (AGI) exceeds $150,000 and you are a married individual filing jointly
   ($95,000 for single taxpayers). Married individuals filing jointly with AGI
   which exceeds $160,000 may not fund a Roth IRA. Married individuals filing
   separately with AGI exceeding $10,000 may not fund a Roth IRA. Single
   individuals with AGI exceeding $110,000 may not fund a Roth IRA.

   If you are married filing jointly and your AGI is between $150,000 and
   $160,000, your maximum Roth IRA contribution is determined as follows: (1)
   Subtract your AGI from $160,000, (2) divide the difference by $10,000, and
   (3) multiply the result in step (2) by $2,000. For example, if your AGI is
   $155,000, your maximum Roth IRA contribution is $1,000. This amount is
   determined as follows: [($160,000 minus $155,000) divided by $10,000]
   multiplied by $2,000.

   If you are single and your AGI is between $95,000 and $110,000, your maximum
   Roth IRA contribution is determined as follows: (1) Subtract your AGI from
   $110,000, (2) divide the difference by $15,000, and (3) multiply the result
   in step (2) by $2,000. For example, if your AGI is $98,000, your maximum Roth
   IRA contribution is $1,600. This amount is determined as follows: [($110,000
   minus $98,000) divided by $15,000] multiplied by $2,000.

   Your Roth IRA contribution is not limited by your participation in a
   retirement plan other than a Traditional IRA, as discussed above. In
   addition, unlike Traditional IRAs, you may continue to fund a Roth IRA after
   age 70 1/2 so long as you have earned income and your AGI is below the
   maximum thresholds discussed above.

                                       8
<PAGE>
 
C. NONFORFEITABILITY - Your interest in your Roth IRA is nonforfeitable.

D. ELIGIBLE CUSTODIANS - The Custodian of your Roth IRA must be a bank, savings
   and loan association, credit union, or a person approved by the Secretary of
   the Treasury.

E. COMMINGLING ASSETS - The assets of your Roth IRA cannot be commingled with
   other property except in a common trust fund or common investment fund.

F. LIFE INSURANCE - No portion of your Roth IRA may be invested in life
   insurance contracts.

G. COLLECTIBLES - You may not invest the assets of your Roth IRA in collectibles
   (within the meaning of Internal Revenue Code (IRC) section 408(m). A
   collectible is defined as any work of art, rug or antique, metal or gem,
   stamp or coin, alcoholic beverage, or other tangible personal property
   specified by the Internal Revenue Service. However, specially minted United
   States gold and silver bullion coins and certain state-issued coins are
   permissible investments. Platinum coins and certain gold, silver, platinum or
   palladium bullion (as described in IRC Sec. 408(m)(3)) are also permitted as
   Roth IRA investments.

H. BENEFICIARY PAYOUTS - If your surviving spouse is your sole beneficiary, your
   spouse may treat your Roth IRA as his or her own Roth IRA and would not be
   subject to the required minimum distribution rules. Your surviving spouse
   will also be entitled to such additional beneficiary payment options as are
   permitted under the law or related regulations. If the beneficiary or
   beneficiaries include anyone other than your surviving spouse, the entire
   amount remaining in your account will, at the election of your beneficiary or
   beneficiaries, either

     (a) be distributed by December 31 of the year containing the fifth
         anniversary of your death, or

     (b) be distributed in equal or substantially equal payments over the life
         or life expectancy of your designated beneficiary or beneficiaries.

   A nonspouse beneficiary or beneficiaries must elect either option (a) or (b)
   by December 31 of the year following the year of your death. If no election
   is made, distribution will be made in accordance with option (a).

INCOME TAX CONSEQUENCES OF ESTABLISHING A ROTH IRA

A. CONTRIBUTIONS NOT DEDUCTED - No deduction is allowed for Roth IRA
   contributions, including transfers and rollover contributions.

B. TAX-DEFERRED EARNINGS - The investment earnings of your Roth IRA are not
   subject to federal income tax as they accumulate in your Roth IRA. In
   addition, distributions of your Roth IRA earnings will be free from federal
   income tax if you take a qualified distribution, as discussed below.

C. TAXATION OF DISTRIBUTIONS - The taxation of a Roth IRA distribution depends
   on whether the distribution is a qualified distribution or a nonqualified
   distribution.

   1. Qualified Distributions - Qualified distributions from your Roth IRA (both
      the contributions and earnings) are not included in gross income. A
      qualified distribution occurs when the assets have been in the Roth IRA
      for five years and one of the following events occurs:

      * attainment of age 59 1/2,
      * disability,

                                       9
<PAGE>
 
      * the purchase of a first home, or
      * death.

      For contributory IRAs, the five-year period begins with the first year for
      which you make a Roth IRA contribution. For example, if you make a
      contribution to your Roth IRA for 1998, the five-year period will be
      completed at the end of 2002. However, a separate five-year requirement
      applies to each rollover contribution from a Traditional IRA. The five-
      year period for these rollovers begins with the year in which the rollover
      contribution is made.

   2. Nonqualified Distributions - If you do not meet the requirements for a
      qualified distribution, any earnings you withdraw from your Roth IRA will
      be included in your gross income and, if you are under age 59 1/2, may be
      subject to an early distribution penalty. However, when you take a
      nonqualified distribution, your basis (the amounts you contributed to the
      account) will generally be removed first. Therefore, your nonqualified
      distributions will not be taxable to you until your withdrawals exceed the
      amount of your contributions. Special rules may apply to the distribution
      of conversion amounts.

D. NO REQUIRED MINIMUM DISTRIBUTIONS - You are not required to take distribution
   from your Roth IRA at age 70 1/2 (as required for Traditional and SIMPLE
   IRAs).

E. ROLLOVERS AND CONVERSIONS - Your Roth IRA may be rolled over to another Roth
   IRA of yours, or may receive rollover contributions, provided that all of the
   applicable rollover rules are followed. Rollover is a term used to describe a
   tax-free movement of cash or other property to your Roth IRA from any of your
   Roth or Traditional IRAs. The rollover rules are generally summarized below.
   These transactions are often complex. If you have any questions regarding a
   rollover, please see a competent tax advisor.

   1. Roth IRA To Roth IRA Rollovers - Funds distributed from your Roth IRA may
      be rolled over to a Roth IRA of yours if the requirements of IRC section
      408(d)(3) are met. A proper Roth IRA to Roth IRA rollover is completed if
      all or part of the distribution is rolled over not later than 60 days
      after the distribution is received. You may not have completed another
      Roth IRA to Roth IRA rollover from the distributing Roth IRA during the 12
      months preceding the date you receive the distribution. Further, you may
      roll the same dollars or assets only once every 12 months. Roth IRA assets
      may not be rolled over to other types of IRAs (e.g., Traditional IRA,
      SIMPLE IRA).

   2. Traditional IRA To Roth IRA Conversions - Unless your adjusted gross
      income is more than $100,000, or you are married filing a separate tax
      return, you are eligible to roll over, transfer or convert all or any
      portion of your existing Traditional IRA(s) into your Roth IRA(s). A
      separate Roth Conversion IRA should generally be established to hold
      conversion amounts. If your Roth IRA is designated as a Roth Conversion
      IRA, the only permissible contributions are amounts converted from a
      Traditional IRA during the same tax year. The amount of the conversion
      from your Traditional IRA to your Roth IRA will be treated as a
      distribution for income tax purposes and is includible in your gross
      income (except for any nondeductible contributions). Although the
      conversion amount is generally included in income, the 10 percent early
      distribution penalty will not apply to

                                      10
<PAGE>
 
      rollovers or conversions from a Traditional IRA to a Roth IRA, regardless
      of whether you qualify for any exceptions to the 10 percent penalty.

      If you convert assets from your Traditional IRA to your Roth IRA prior to
      January 1, 1999, you must include the taxable amount of the distribution
      in your gross income ratably over a four year period beginning with 1998.

   3. Written Election - At the time you make a proper rollover to a Roth IRA,
      you must designate to the Custodian, in writing, your election to treat
      that contribution as a rollover. Once made, the rollover election is
      irrevocable.

   4. No Rollovers From Employer Plans - You may not roll over distributions
      from your employer's qualified retirement plan or 403(b) arrangement into
      your Roth IRA.

F. CARRYBACK CONTRIBUTIONS - A contribution is deemed to have been made on the
   last day of the preceding taxable year if you make a contribution by the
   deadline for filing your income tax return (not including extensions), and
   you designate that contribution as a contribution for the preceding taxable
   year. For example, if you are a calendar year taxpayer and you make your Roth
   IRA contribution on or before April 15, your contribution is considered to
   have been made for the previous tax year if you designate it as such.

LIMITATIONS AND RESTRICTIONS

A. SPOUSAL ROTH IRA - If you are married, you may make payments to a Roth IRA
   established for the benefit of your spouse. You must file a joint tax return
   for the year for which the contribution is made.

   The amount you may contribute to your Roth IRA and your spouse's Roth IRA is
   the lesser of $4,000 or 100 percent of your combined compensation. However,
   you may not contribute more than $2,000 to any one Roth IRA. Your
   contribution may be further limited if your AGI exceeds the levels discussed
   in the section titled Maximum Contribution.

B. ESTATE TAX EXCLUSION - The $100,000 federal estate tax exclusion previously
   available has been repealed for individuals dying after December 31, 1984. No
   exclusion will be allowed for individuals dying after that date. Transfers of
   your Roth IRA assets to a named beneficiary made during your life and at your
   request or because of your failure to instruct otherwise, may be subject to
   federal gift tax under IRC section 2501 if made after October 22, 1986.

C. SPECIAL TAX TREATMENT - Capital gains treatment and the favorable five or ten
   year forward averaging tax authorized by IRC section 402 do not apply to Roth
   IRA distributions.

D. INCOME TAX TREATMENT - Any nonqualified withdrawal of earnings from your Roth
   IRA, is subject to federal income tax withholding. You may, however, elect
   not to have withholding apply to your Roth IRA withdrawal. If withholding is
   applied to your withdrawal, not less than 10 percent of the amount withdrawn
   must be withheld.

E. PROHIBITED TRANSACTIONS - If you or your beneficiary engage in a prohibited
   transaction with your Roth IRA, as described in IRC section 4975, your Roth
   IRA will lose its tax-exempt status and you must generally include

                                      11
<PAGE>
 
   the value of the earnings in your account in your gross income for that
   taxable year.

F. PLEDGING - If you pledge any portion of your Roth IRA as collateral for a
   loan, the amount so pledged will be treated as a distribution and may be
   included in your gross income for that year to the extent it represents
   earnings.

FEDERAL TAX PENALTIES

A. EARLY DISTRIBUTION PENALTY - If you are under age 59 1/2 and receive a
   nonqualified Roth IRA distribution, an additional tax of 10 percent will
   apply to the amount includible in income (i.e., the earnings), unless the
   distribution is made on account of death, disability, a qualifying rollover,
   a direct transfer, the timely withdrawal of an excess contribution; or if the
   distribution is part of a series of substantially equal periodic payments (at
   least annual payments) made over your life expectancy or the joint life
   expectancy of you and your beneficiary. Payments made to pay medical expenses
   which exceed 7.5 percent of your adjusted gross income and distributions to
   pay for health insurance by an individual who has separated from employment
   and who has received unemployment compensation under a federal or state
   program for at least 12 weeks are also exempt from the 10 percent tax.
   Payments to cover certain qualified education expenses and distributions for
   first-home purchases (up to life-time maximum of $10,000) are exempt from the
   10 percent tax. This additional tax will apply only to the portion of a
   distribution which is includible in your income.


B. EXCESS CONTRIBUTION PENALTY - An excise tax of 6 percent is imposed upon any
   excess contribution you make to your Roth IRA. This tax will apply each year
   in which an excess remains in your Roth IRA. An excess contribution is any
   contribution amount which exceeds your contribution limit, excluding rollover
   and direct transfer amounts. Your contribution limit is the lesser of $2,000
   or 100 percent of your compensation for the taxable year. Your contribution
   may be further limited if your AGI exceeds the levels discussed in the
   section titled Maximum Contribution.

C. EXCESS ACCUMULATION PENALTY - Unless your sole beneficiary is your surviving
   spouse, your designated beneficiary(ies) is required to take certain minimum
   distributions after your death. An additional tax of 50 percent is imposed on
   the amount of the required minimum distribution which should have been taken
   but was not. This tax is referred to as an excess accumulation penalty tax.

D. PENALTY REPORTING - You must file Form 5329 with the Internal Revenue Service
   to report and remit any penalties or excise taxes.

ARBITRATION

By signing the agreement, you agree that any controversy arising out of or
relating to your Account, any transaction made under your Account, or the
performance or breach of the Agreement shall be settled by arbitration as
described in Article 9 of the Custodial Agreement and paragraph 20 of the Roth
IRA account application.

You may direct the investment of your funds within this Roth IRA into any
investment instrument offered by or through the Custodian. The Custodian will
not exercise any investment discretion regarding your Roth IRA, as this is
solely your responsibility.

The value of your Roth IRA will be solely dependent upon the performance of any
investment instrument chosen by you to fund your Roth IRA.  Therefore, no
projection of the growth of your Roth IRA can reasonably be shown or guaranteed.
