                                    SUMMARY
 
  The Trust, a management investment company, was established as Massachusetts
business trust under a Declaration of Trust dated February 10, 1987. The
Declaration of Trust permits the Trust to offer separate series of shares of
beneficial interest representing interests in separate portfolios of
securities. The shares in any one Fund may be offered in separate classes. As
of the date of this Prospectus, the Board of Trustees has established two
classes of shares, known as Trust Shares and Investment Shares, in the Money
Market Fund, the Ohio Municipal Money Market Fund, the U.S. Treasury Money
Market Fund, the Growth Fund, the Mortgage Securities Fund, the Ohio Tax-Free
Fund, and the Fixed Income Securities Fund. All of the portfolios of the
Trust, with the exception of the Ohio Municipal Money Market Fund and the Ohio
Tax-Free Fund, are diversified. This Prospectus relates solely to the
Investment Shares of each Fund as set forth below.
 
  As of the date of this Prospectus, the Funds offered in the Investment Share
class by this Prospectus are as follows:
 
  MONEY MARKET FUNDS--INVESTMENT SHARES
    MONEY MARKET FUND--seeks to maximize current income while preserving
    capital and maintaining liquidity by investing in a portfolio of high
    quality money market instruments;
    OHIO MUNICIPAL MONEY MARKET FUND--seeks to provide income exempt from
    both federal regular income tax and Ohio personal income taxes while
    preserving capital and maintaining liquidity by investing in Ohio tax-
    exempt securities;
    U.S. TREASURY MONEY MARKET FUND--seeks to maximize current income while
    preserving capital and maintaining liquidity by investing exclusively
    in obligations issued by the U.S. Government and backed by its full
    faith and credit, and in repurchase agreements with respect to such
    obligations;
  EQUITY FUND--INVESTMENT SHARES
    GROWTH FUND--seeks to achieve long-term capital appreciation by
    investing primarily in equity securities;
  INCOME FUNDS--INVESTMENT SHARES
    MORTGAGE SECURITIES FUND--seeks to achieve current income by investing
    in mortgage securities and in U.S. Government securities;
    OHIO TAX-FREE FUND--seeks to provide current income exempt from federal
    income taxes and Ohio personal income taxes by investing in Ohio tax-
    exempt securities; and
    FIXED INCOME SECURITIES FUND--seeks to achieve high current income by
    investing in fixed income securities where the average maturity of the
    Fund will not exceed 10 years.
 
  For information on how to purchase Investment Shares of any of the Funds,
please refer to "How to Buy Investment Shares." A minimum initial investment
of $1,000 is required for each Fund. Subsequent investments in a Fund must be
in amounts of at least $50. Investment Shares of each Fund are sold at net
asset value plus a sales charge where applicable. Shares of each Fund are
redeemed at net asset value. Information on redeeming shares may be found
under "How to Redeem Investment Shares." The Funds are advised by The
Huntington Trust Company, N.A. In addition, Piper Capital Management
Incorporated ("Piper"), a wholly-owned subsidiary of Piper Jaffray Companies
Inc., serves as sub-adviser to the Mortgage Securities Fund.

RISK FACTORS. Investors should be aware of the following general observations.
There can be no assurance that a Fund will achieve its investment objective.
The market value of fixed-income securities, which constitute a major part of
the investments of several Funds, may vary inversely in response to changes in
prevailing interest rates ("interest rate risk"). Shareholders of the Ohio
Municipal Money Market Fund and the Ohio Tax-Free Fund may be subject to the
federal alternative minimum tax on that part of the Funds' dividends derived
from interest on certain municipal securities. One or more Funds may make
certain investments and employ certain investment techniques that involve
special risks, including the use of repurchase agreements, lending portfolio
securities, entering into futures contracts and related options as hedges,
investing in foreign securities, and purchasing securities on a when-issued or
delayed delivery basis, including the use of "dollar rolls." These investments
and investment techniques may increase the volatility of a Fund's net asset
value. Their risks are described under "Additional Information on Portfolio
Investments and Strategies." The Mortgage Securities Fund may engage in short-
term trading in attempting to achieve its investment objective, which will
increase transaction costs. The Mortgage Securities Fund may purchase
mortgage-related securities including derivative mortgage securities. In
addition to interest rate risk, mortgage-related securities are subject to
prepayment risk. Recent market experience has shown that certain derivative
mortgage securities may be extremely sensitive to changes in interest rates
and in prepayment rates on the underlying assets and, as a result, the prices
of such securities may be highly volatile.

(1)Fees paid by each Fund for investment advisory services. See "Management of
the Trust."
(2) Fees paid by Investment Shares of each Fund for distribution services
    provided with respect to Investment Shares. Total payments of up to 1% for
    all Funds except the Mortgage Securities Fund, and up to 0.50 of 1% for
    the Mortgage Securities Fund, of the average daily net assets attributable
    to Investment Shares are permitted under the Distribution Plans. The
    Distributor can terminate these voluntary waivers at any time in its sole
    discretion. See "Management of the Trust--Distribution Plans."
(3) Includes administration fees. See "Management of the Trust--Administration
    of the Funds."
(4) The Total Investment Shares Operating Expenses for the Ohio Municipal
    Money Market Fund would have been 0.82%, absent the voluntary waiver of
    management fees and 12b-1 fees. The maximum management fee for Ohio
    Municipal Money Market Fund is 0.30%. The Total Investment Shares
    Operating Expenses for the Money Market Fund and the U.S. Treasury Money
    Market Fund would have been 0.78% and 0.68%, respectively, absent the
    voluntary waiver by the Distributor.
5) The Total Investment Shares Operating Expenses for the Mortgage Securities
   Fund in the table above are different than those incurred during the fiscal
   year ending December 31, 1995, due to a reduction, subsequent to December
   31, 1995, in the level of fee waiver. Absent the voluntary waiver of
   management and 12b-1 fees, the total fund operating expenses would be
   1.49%. The maximum management fee is 0.50%.
* The adviser, administrator and/or custodian can terminate these voluntary
  waivers at any time at their sole discretion.
EXAMPLE:
You would pay the following expenses on a $1,000 investment, assuming (1) 5%
annual return and (2) redemption at the end of each time period, and (3)
payment of maximum sales load:

  The purpose of the foregoing example is to assist an investor in
understanding the various costs and expenses that a shareholder of Investment
Shares will bear directly or indirectly. The example should not be considered
a representation of past or future expenses. Actual expenses may be greater or
less than those shown.
  Long-term shareholders may pay more than the economic equivalent of the
maximum front-end sales charges permitted under the rules of the National
Association of Securities Dealers, Inc.

                 THE FUNDS' INVESTMENT OBJECTIVES AND POLICIES
 
  The investment objectives and policies of the various Funds are described
below. There can, of course, be no guarantee that a Fund will achieve its
investment objective.
 
  Each Fund's investment objective is fundamental and may be changed only by a
vote of a majority of the outstanding shares of that Fund. Unless otherwise
noted in this Prospectus or in the Statement of Additional Information, the
investment policies of the Funds are not fundamental and may be changed by the
Trust's Board of Trustees (the "Trustees"). Except with respect to borrowing
money or downgrades of securities in the Money Market Funds, any percentage
limitation on a Fund's investments (or other activities) will be considered to
be violated only if such limitation is exceeded immediately after, and is
caused by, an acquisition of an investment (or the taking of such other

                              MONEY MARKET FUNDS
 
  Each of the Money Market Funds described below is designed for investors
seeking current income with stability of principal. The Money Market Funds
intend to limit their investments by operating in a manner consistent with
Rule 2a-7 under the Investment Company Act of 1940, as amended (the "1940
Act"). Rule 2a-7 permits funds to utilize the amortized cost method of
valuation in order to offer their shares at a net asset value of $1.00 per
share (see also the section of the Statement of Additional Information
entitled, "Determination of Net Asset Value"). Rule 2a-7 imposes certain risk
limiting conditions on the Money Market Funds which in some instances restrict
a Money Market Fund's investment policies. These risk limiting conditions
include the following:
 
 . The Money Market Funds must limit their investments to "Eligible Securities"
  as defined under Rule 2a-7, and which Huntington has determined present
  minimal credit risks under guidelines adopted by the Trustees. (For an
  explanation of some of the terms defined by Rule 2a-7, see Appendix I to
  this Prospectus.)
 
 . Each Money Market Fund (except the Ohio Municipal Money Market Fund) must
  limit investments in "Second Tier Securities" to 5% of total assets and 1%
  of total assets in the securities of a single Second Tier issuer.
 
 . The Money Market Funds may invest without limit in "First Tier Securities"
  subject to the 5% issuer diversification limitation where applicable. In
  addition, the portfolio investments of each Money Market Fund must have a
  maturity of 397 days or less from the time of purchase by it, although
  securities owned pursuant to a repurchase agreement and certain adjustable
  interest rate instruments may bear longer maturities. The dollar-weighted
  average maturity of each Money Market Fund's portfolio must not exceed 90
  days. Of course, a Money Market Fund's yield, and under unusual
  circumstances, the value of its portfolio securities, will be affected by
  changes in interest rates.
 
MONEY MARKET FUND
 
  The objective of the Money Market Fund is to maximize current income while
preserving capital and maintaining liquidity by investing in a portfolio of
high quality money market instruments. The Money Market Fund's portfolio
investments may include:
 
  (a)  obligations, such as notes, bills or bonds, issued by or guaranteed as
       to principal and interest by the U.S. Government or its agencies or
       instrumentalities;
 
                                      10
<PAGE>
 
 
  (b)  commercial paper, including U.S. dollar denominated eurodollar
       commercial paper, considered under Rule 2a-7 to be rated in the highest
       category by an NRSRO(s) or, if not rated, of comparable quality as
       determined by Huntington pursuant to guidelines established by the
       Trustees;
 
  (c)  negotiable certificates of deposit and bankers' acceptances issued by
       domestic banks and U.S. branches of foreign banks which are subject to
       the same regulation as U.S. banks and which, at the time of purchase,
       have capital, surplus, and undivided profits in excess of $100,000,000
       (as of the bank's most recently published financial statements);
 
  (d)  corporate debt obligations, including bonds, notes and debentures
       considered under Rule 2a-7 to be rated in the two highest categories by
       an NRSRO(s) or, if not rated, of comparable quality as determined by
       Huntington pursuant to guidelines established by the Trustees; and
 
  (e)  repurchase agreements and master demand notes.
 
  RESTRICTED AND ILLIQUID SECURITIES. The Money Market Fund intends to invest
in restricted securities. Restricted securities are any securities in which
the Money Market Fund may otherwise invest pursuant to its investment
objective and policies but which are subject to restriction on resale under
federal securities law. However, the Money Market Fund will limit investments
in illiquid securities, including certain restricted securities not determined
by the Trustees to be liquid, non-negotiable time deposits, and repurchase
agreements providing for settlement in more than seven days after notice, to
10% of its net assets.
 
The Money Market Fund may invest in commercial paper issued in reliance on the
exemption from registration afforded by Section 4(2) of the Securities Act of
1933. Section 4(2) commercial paper is restricted as to disposition under
federal securities law, and is generally sold to institutional investors, such
as the Money Market Fund, who agree that they are purchasing the paper for
investment purposes and not with a view to public distribution. Any resale by
the purchaser must be in an exempt transaction. Section 4(2) commercial paper
is normally resold to other institutional investors like the Money Market Fund
through or with the assistance of the issuer or investment dealers who make a
market in Section 4(2) commercial paper, thus providing liquidity. The Money
Market Fund believes that Section 4(2) commercial paper and possibly certain
other restricted securities which meet the criteria for liquidity established
by the Trustees are quite liquid. The Money Market Fund intends, therefore, to
treat the restricted securities which meet the criteria for liquidity
established by the Trustees, including Section 4(2) commercial paper, as
determined by Huntington, as liquid and not subject to the investment
limitation applicable to illiquid securities. In addition, because Section
4(2) commercial paper is liquid, the Money Market Fund intends to not subject
such paper to the limitation applicable to restricted securities.
 
OHIO MUNICIPAL MONEY MARKET FUND
 
  The objective of the Ohio Municipal Money Market Fund is to provide income
exempt from both federal regular income tax and Ohio personal income taxes
while preserving capital and maintaining liquidity. As a fundamental policy,
the Ohio Municipal Money Market Fund invests its assets so that at least 80%
of its annual interest income is exempt from federal regular income tax. The
Ohio Municipal Money Market Fund invests primarily in Ohio tax-exempt
securities which, under normal market conditions, will comprise at least 65%
of its assets. Ohio tax-exempt securities are debt obligations issued by or on
behalf of the State of Ohio, its political subdivisions, or agencies, or
financing authorities of any of these, the income from which is, in the
opinion of qualified legal counsel, exempt from both federal regular income
tax and the personal income taxes imposed by the State of Ohio. Examples of
tax-exempt securities include, but are not limited to:
 
 
                                      11
<PAGE>
 
 . tax and revenue anticipation notes ("TRANs") issued to finance working
  capital needs in anticipation of receiving taxes or other revenues;
 
 . bond anticipation notes ("BANs") that are intended to be refinanced through
  a later issuance of longer-term bonds;
 
 . municipal commercial paper and other short-term notes;
 
 . variable rate demand notes;
 
 . municipal bonds (including bonds having serial maturities and pre-refunded
  bonds); and
 
 . participation, trust and partnership interests in any of the foregoing
  obligations.
 
  VARIABLE RATE DEMAND OBLIGATIONS. Variable rate demand obligations are long-
term tax-exempt securities that have variable or floating interest rates and
provide the Ohio Municipal Money Market Fund with the right to tender the
security for repurchase at its stated principal amount plus accrued interest.
Such securities typically bear interest at a rate that is intended to cause
the securities to trade at par. The interest rate may float or be adjusted at
regular intervals (ranging from daily to annually), and is normally
established by the remarketing agent of the respective securities. Most
variable rate demand obligations allow the holder to demand the repurchase of
the security on not more than seven days prior notice. Other obligations only
permit the holder to tender the security at the time of each interest rate
adjustment or at other fixed intervals. See "Demand Features." The Ohio
Municipal Money Market Fund treats variable rate demand obligations as
maturing on the later of the date of the next interest adjustment or the date
on which it may next tender the security for redemption.
 
  PARTICIPATION INTERESTS. The Ohio Municipal Money Market Fund may purchase
interests in tax-exempt securities from financial institutions such as
commercial and investment banks, savings and loan associations and insurance
companies. These interests may take the form of participations, beneficial
interests in a trust, partnership interests or any other form of indirect
ownership that allows the holder to treat the income from the investment as
exempt from federal income tax. The Ohio Municipal Money Market Fund invests
in these participation interests in order to obtain credit enhancement or
demand features that would not be available through direct ownership of the
underlying tax-exempt securities.
 
  CREDIT ENHANCEMENT. Certain of the portfolio investments of the Ohio
Municipal Money Market Fund may have been credit enhanced by a guaranty,
letter of credit or insurance. The Ohio Municipal Money Market Fund typically
evaluates the credit quality and ratings of credit enhanced securities based
upon the financial condition and ratings of the party providing the credit
enhancement (the "credit enhancer"), rather than the issuer. However, credit
enhanced securities will not be treated as having been issued by the credit
enhancer for diversification purposes, unless the Ohio Municipal Money Market
Fund has invested more than 10% of its assets in securities issued, guaranteed
or otherwise credit enhanced by the credit enhancer, in which case the
securities will be treated as having been issued both by the issuer and the
credit enhancer. The bankruptcy, receivership or default of the credit
enhancer will adversely affect the quality and marketability of the underlying
security.
 
  The Ohio Municipal Money Market Fund may have more than 25% of its total
assets invested in securities credit enhanced by banks.
 
  DEMAND FEATURES. The Ohio Municipal Money Market Fund may acquire securities
that are subject to puts and standby commitments ("demand features") to
purchase the securities at their principal amount (usually with accrued
interest) within a fixed period (usually seven days) following a demand by the
fund. The demand feature may be issued by the issuer of the underlying
securities, a dealer in the securities or by another third party, and may not
be transferred separately from the
 
                                      12
<PAGE>
 
underlying security. The Ohio Municipal Money Market Fund uses these
arrangements to provide liquidity and not to protect against changes in the
market value of the underlying securities. The bankruptcy, receivership or
default by the issuer of the demand feature, or a default on the underlying
security or other event that terminates the demand feature before its
exercise, will adversely affect the liquidity of the underlying security.
Demand features that are exercisable even after a payment default on the
underlying security may be treated as a form of credit enhancement.
 
  TEMPORARY INVESTMENTS.  The Ohio Municipal Money Market Fund invests its
assets so that at least 80% of its annual interest income is exempt from
federal regular income taxes and at least 65% of its assets are invested in
securities the income from which is exempt from Ohio personal income taxes.
However, from time to time, when Huntington determines that market conditions
call for a temporary defensive posture, the Ohio Municipal Money Market Fund
may invest in temporary investments with remaining maturities of 13 months or
less at the time of purchase, or hold assets in cash. Interest income from
temporary investments may be taxable to shareholders as ordinary income. These
temporary investments include: obligations issued by or on behalf of municipal
or corporate issuers having the same quality characteristics as Ohio tax-
exempt securities purchased by the Fund; marketable obligations issued or
guaranteed by the U.S. Government, its agencies, or instrumentalities;
instruments issued by a U.S. branch of a domestic bank or other depository
institutions having capital, surplus, and undivided profits in excess of
$100,000,000 at the time of investment; repurchase agreements (arrangements in
which the organization selling a temporary investment agrees at the time of
sale to repurchase it at a mutually agreed upon time and price); and
commercial paper rated in one of the two highest short-term rating categories
by an NRSRO(s).
 
  Although the Ohio Municipal Money Market Fund is permitted to make taxable,
temporary investments that may have Ohio state tax implications, there is no
current intention of generating income subject to federal regular or Ohio
personal income taxes.
 
U.S. TREASURY MONEY MARKET FUND
 
  The objective of the U.S. Treasury Money Market Fund is to maximize current
income while preserving capital and maintaining liquidity by investing
exclusively in obligations issued by the U.S. Government and backed by its
full faith and credit and in repurchase agreements with respect to such
obligations. At least 65% of the U.S. Treasury Money Market Fund's total
assets will be invested in Treasury bills, notes and bonds which are direct
obligations of the U.S. Treasury, and repurchase agreements with respect to
such obligations.
 
 
                                  EQUITY FUND
 
GROWTH FUND
 
  The objective of the Growth Fund is to achieve long-term capital
appreciation primarily through investments in equity securities. Current
income will be only an incidental consideration in the selection of
investments. Equity securities in which the Growth Fund may invest include
common stocks, preferred stocks, securities convertible into or exchangeable
for common stocks, and other securities which Huntington believes have common
stock characteristics, such as rights and warrants. The Growth Fund may invest
in foreign securities and, subject to its investment restrictions, securities
restricted as to resale under federal securities laws. The Growth Fund's
common stock selection emphasizes those companies which Huntington believes
have characteristics such as above average earnings and dividend growth,
superior balance sheets, and potential for capital gains, but its
 
                                      13
<PAGE>
 
investment policy recognizes that securities of other companies may be
attractive for capital appreciation purposes by virtue of special developments
or depression in price believed to be temporary. The Growth Fund will invest
in large and medium-sized capitalization growth companies which provide these
financial and growth characteristics. In managing the investments of the
Growth Fund, Huntington seeks to purchase equity securities whose potential
for capital gains is balanced by an ability to better withstand overall
downward market movements. As a matter of fundamental policy, under normal
market conditions, the Growth Fund will invest at least 65% of its total
assets in the equity securities described in this paragraph. The Growth Fund
may also, under normal market conditions, invest a portion of its assets in
cash equivalents, including repurchase agreements and the shares of money
market mutual funds, for liquidity purposes.
 
                                 INCOME FUNDS
 
  The investment objectives and policies of the Income Funds are described
below. Each of the Income Funds invests primarily in debt securities. The
prices of fixed income securities generally fluctuate inversely to the
direction of interest rates. Thus, a decrease in interest rates will generally
result in an increase in the values of debt securities held by an Income Fund.
Conversely, during periods of rising interest rates, the values of an Income
Fund's assets will generally decline. The values of such securities are also
affected by changes in the financial condition of their issuers. Changes in
the values of an Income Fund's securities will not generally affect the income
derived from such securities but will affect an Income Fund's net asset value.
 
MORTGAGE SECURITIES FUND
 
  The investment objective of the Mortgage Securities Fund is current income.
The Mortgage Securities Fund seeks to achieve this investment objective by
investing at least 65% of the value of its total assets in mortgage-related
securities issued by the U.S. Government, government-related entities, and
private entities. These mortgage-related securities include derivative
mortgage securities. Recent market experience has shown that certain
derivative mortgage securities may be extremely sensitive to changes in
interest rates and in prepayment rates on the underlying mortgage assets, and,
as a result, the prices of such securities may be highly volatile.
 
  The Mortgage Securities Fund may invest up to 35% of the value of its total
assets in:
 
    (i) non-mortgage related securities issued or guaranteed by the U.S.
  Government, its agencies, or instrumentalities;
 
    (ii) certificates of deposit, bankers' acceptances and interest-bearing
  savings deposits of banks having total assets of more than $1 billion and
  which are members of the Federal Deposit Insurance Corporation (the
  "FDIC"); and
 
    (iii) commercial paper rated A-1 by Standard & Poor's Ratings Group
  ("S&P") or P-1 by Moody's Investors Service, Inc. ("Moody's") or, if not
  rated, issued by companies which have an outstanding debt issue rated AAA
  by S&P or Aaa by Moody's.
 
  The Mortgage Securities Fund will attempt to maintain a dollar-weighted
average portfolio life of more than three years but no more than ten years. In
order to maintain this dollar-weighted average portfolio life, Huntington will
monitor the prepayment experience of the underlying mortgage pools of the
mortgage-related securities and will purchase and sell securities in the
portfolio to shorten or lengthen the average life of the portfolio, as
appropriate.
 
                                      14
<PAGE>
 
 
  It is important to understand that, while a valuable measure, average life
is based on certain assumptions and has several limitations. It is most useful
as a measure of the repayment of principal when interest rate changes are
small. In addition, average life is difficult to calculate precisely for bonds
with prepayment options, such as mortgage-related securities, because the
calculation requires assumptions about prepayment rates. For example, when
interest rates go down, homeowners may prepay their mortgages at a higher rate
than assumed in the initial securities. Conversely, if rates increase,
prepayments may decrease to a greater extent than assumed, extending the
average life of such securities. For these reasons, average lives of funds
which invest a significant portion of their assets in mortgage-related
securities can be greatly affected by changes in interest rates.
 
MORTGAGE-RELATED SECURITIES. Mortgage-related securities are securities that,
directly or indirectly, represent participations in, or are secured by and
payable from, loans secured by real property. Mortgage-related securities, as
the term is used in this Prospectus, include mortgage pass-through securities,
adjustable rate mortgage securities, collateralized mortgage obligations and
stripped mortgage-backed securities. These mortgage-related securities include
derivative mortgage securities. Mortgage-related securities fall into three
categories: (a) those issued or guaranteed by the U.S. Government or one of
its agencies or instrumentalities, such as Government National Mortgage
Association ("GNMA"), Federal National Mortgage Association ("FNMA") and
Federal Home Loan Mortgage Corporation ("FHLMC"); (b) those issued by non-
governmental issuers that represent interests in, or are collateralized by,
mortgage-related securities issued or guaranteed by the United States
Government or one of its agencies or instrumentalities; and (c) those issued
by non-governmental issuers that represent an interest in, or are
collateralized by, whole mortgage loans or mortgage-related securities without
a government guarantee but usually with over-collateralization or some other
form of private credit enhancement. Non-governmental issuers referred to in
(b) and (c) above include originators of and investors in mortgage loans,
including savings and loan associations, mortgage bankers, commercial banks,
investment banks and special purpose subsidiaries of the foregoing.
 
  MORTGAGE PASS-THROUGH SECURITIES. The mortgage pass-through securities in
which the Mortgage Securities Fund invests provide for the pass-through to
investors of their pro-rata share of monthly payments (including any
prepayments) made by the individual borrowers on the pooled mortgage loans,
net of any fees paid to the guarantor of such securities and the servicer of
the underlying mortgage loans. The Mortgage Securities Fund invests both in
U.S. Government pass-through securities issued by GNMA, FNMA and FHLMC, and in
pass-through securities issued by non-governmental issuers. Each of GNMA, FNMA
and FHLMC guarantee timely distributions of interest to certificate holders.
GNMA and FNMA guarantee timely distributions of scheduled principal. FHLMC
generally guarantees only ultimate collection of principal of the underlying
mortgage loans.
 
  ADJUSTABLE RATE MORTGAGE SECURITIES. The Mortgage Securities Fund may also
invest in adjustable rate mortgage securities ("ARMS"). ARMS are pass-through
mortgage securities collateralized by mortgages with interest rates that are
adjusted from time to time. The adjustments usually are determined in
accordance with a predetermined interest rate index and may be subject to
certain limits. While the values of ARMS, like other debt securities,
generally vary inversely with changes in market interest rates (increasing in
value during periods of declining interest rates and decreasing in value
during periods of increasing interest rates), the values of ARMS should
generally be more resistant to price swings than other debt securities because
the interest rates of ARMS move
 
                                      15
<PAGE>
 
with market interest rates. The adjustable rate feature of ARMS will not,
however, eliminate fluctuations in the prices of ARMS, particularly during
periods of extreme fluctuations in interest rates. Also, since many adjustable
rate mortgages only reset on an annual basis, it can be expected that the
prices of ARMS will fluctuate to the extent that changes in prevailing
interest rates are not immediately reflected in the interest rates payable on
the underlying adjustable rate mortgages.
 
  COLLATERALIZED MORTGAGE OBLIGATIONS. The Mortgage Securities Fund may invest
in CMOs (collateralized mortgage obligations and multi-class pass-through
securities unless the context otherwise indicates), which are derivative
mortgage securities. Collateralized mortgage obligations are debt instruments
issued by special purpose entities which are secured by pools of mortgage
loans or other mortgage-related securities. Multi-class pass-through
securities are equity interests in a trust composed of mortgage loans or other
mortgage-related securities. Payments of principal and interest on underlying
collateral provide the funds to pay debt service on the collateralized
mortgage obligation or make scheduled distributions on the multi-class pass-
through security. The Mortgage Securities Fund will invest only in CMOs which
are rated AAA by an NRSRO.
 
  In a CMO, a series of bonds or certificates is issued in multiple classes.
Each class of CMO, often referred to as a "tranche," is issued at a specific
coupon rate and has a stated maturity or final distribution date. Principal
prepayments on collateral underlying a CMO may cause it to be retired
substantially earlier than the stated maturities or final distribution dates.
 
  The principal and interest on the underlying mortgages may be allocated
among the several tranches of a CMO in many ways. For example, certain
tranches may have variable or floating interest rates and others may be
stripped securities which provide only the principal or interest feature of
the underlying security. See "Stripped Mortgage-Backed Securities," below.
Generally, the purpose of the allocation of the cash flow of a CMO to the
various tranches is to obtain a more predictable cash flow to certain of the
individual tranches than exists with the underlying collateral of the CMO. As
a general rule, the more predictable the cash flow is on a CMO tranche, the
lower the anticipated yield will be on that tranche at the time of issuance
relative to prevailing market yields on mortgage-related securities. As part
of the process of creating more predictable cash flows on most of the tranches
of a CMO, one or more tranches generally must be created that absorb most of
the volatility in the cash flows on the underlying mortgage loans. The yields
on these tranches, which may include inverse floaters, IOs, POs, and Z
tranches, discussed below, are generally higher than prevailing market yields
on mortgage-related securities with similar maturities. As a result of the
uncertainty of the cash flows of these tranches, the market prices of and
yield on these tranches generally are more volatile.
 
  The Mortgage Securities Fund may invest in any CMO tranche, including
"inverse floaters" and "Z tranches." An inverse floater is a CMO tranche with
a coupon rate that moves inversely to a designated index, such as LIBOR
(London Inter-Bank Offered Rate) or COFI (Cost of Funds Index). Like most
other fixed-income securities, the value of inverse floaters will decrease as
interest rates increase. Inverse floaters, however, exhibit greater price
volatility than the majority of mortgage pass-through securities or CMOs.
Coupon rates on inverse floaters typically change at a multiple of the changes
in the relevant index rate. Thus, any rise in the index rate (as a consequence
of an increase in interest rates) causes a correspondingly greater drop in the
coupon rate of an inverse floater while any drop in the index rate causes a
correspondingly greater increase in the coupon of an inverse floater. Some
inverse floaters also exhibit extreme sensitivity to changes in prepayments.
Inverse floaters would be purchased by the Fund to attempt to protect against
a reduction in the income earned on the Fund's investments due to a decline in
interest rates.
 
                                      16
<PAGE>
 
 
  Z tranches of CMOs defer interest and principal payments until one or more
other classes of the CMO have been paid in full. Interest accretes on the Z
tranche, being added to principal, and is compounded through the accretion
period. After the other classes have been paid in full, interest payments
begin and continue through maturity. Z tranches have characteristics similar
to zero coupon bonds. Like a zero coupon bond, during its accretion period a Z
tranche has the advantage of eliminating the risk of reinvesting interest
payments at lower rates during a period of declining market interest rates. At
the same time, however, and also like a zero coupon bond, the market value of
a Z tranche can be expected to fluctuate more widely with changes in market
interest rates than would the market value of a tranche which pays interest
currently. In addition, changes in prepayment rates on the underlying mortgage
loans will affect the accretion period of a Z tranche, and therefore also will
influence its market value.
 
  STRIPPED MORTGAGE-BACKED SECURITIES. Some of the mortage-related securities
purchased by the Mortgage Securities Fund may represent an interest solely in
the principal repayments or solely in the interest payments on mortgage-backed
securities (stripped mortgage-backed securities or "SMBSs"). SMBSs are
derivative multi-class securities. SMBSs are usually structured with two
classes and receive different proportions of the interest and principal
distributions on the pool of underlying mortgage-backed securities. Due to the
possibility of prepayments on the underlying mortgages, SMBSs may be more
interest-rate sensitive than other securities purchased by the Mortgage
Securities Fund. If prevailing interest rates fall below the level at which
SMBSs were issued, there may be substantial prepayments on the underlying
mortgages, leading to the relatively early prepayments of principal-only SMBSs
(the principal-only or "PO" class) and a reduction in the amount of payments
made to holders of interest-only SMBSs (the interest-only or "IO" class).
Therefore, interest-only SMBSs generally increase in value as interest rates
rise and decrease in value as interest rates fall, counter to changes in value
experienced by most fixed income securities. If the underlying mortgages
experience slower than anticipated prepayments of principal, the yield on a PO
class will be affected more severely than would be the case with a traditional
mortgage-related security. Because the yield to maturity of an IO class is
extremely sensitive to the rate of principal payments (including prepayments)
on the related underlying mortgage-backed securities, it is possible that the
Mortgage Securities Fund might not recover its original investment on
interest-only SMBSs if there are substantial prepayments on the underlying
mortgages. The Mortgage Securities Fund's inability to fully recoup its
investment in these securities as a result of a rapid rate of principal
prepayments may occur even if the securities are rated AAA by an NRSRO. In
view of these considerations, Huntington or Piper intends to use these
characteristics of interest-only SMBSs to reduce the effects of interest rate
changes on the value of the Mortgage Securities Fund's portfolio, while
continuing to pursue current income.
 
U.S. GOVERNMENT SECURITIES. The U.S. government securities in which the
Mortgage Securities Fund invests are either issued or guaranteed as to payment
of principal and interest by the U.S. Government, its agencies, or
instrumentalities. The current market prices for such securities are not
guaranteed and will fluctuate. Investments in U.S. Government securities are
limited to:
 
  (a)direct obligations of the U.S. Treasury, such as U.S. Treasury bills,
         notes, and bonds; and
 
  (b)notes, bonds, and discount notes of U.S. Government agencies or
     instrumentalities, such as the: Farm Credit System, including the
     National Bank for Cooperatives and Banks for Cooperatives; Federal Home
     Loan Banks; Federal Home Loan Mortgage Corporation; Federal National
     Mortgage Association; Government National Mortgage Association; Export-
 
                                      17
<PAGE>
 
     Import Bank of the United States; Commodity Credit Corporation; Federal
     Financing Bank; The Student Loan Marketing Association; National Credit
     Union Administration; and Tennessee Valley Authority.
 
  Some obligations issued or guaranteed by agencies or instrumentalities of
the U.S. Government, such as Government National Mortgage Association
participation certificates, are backed by the full faith and credit of the
U.S. Treasury. No assurances can be given that the U.S. Government will
provide financial support to other agencies or instrumentalities, since it is
not obligated to do so. These instruments are supported by:
 
  (a)the issuer's right to borrow an amount limited to a specific line of
     credit from the U.S. Treasury;
 
  (b)the discretionary authority of the U.S. Government to purchase certain
     obligations of an agency or instrumentality; or
 
  (c)the credit of the agency or instrumentality.
 
SHORT-TERM TRADING. The Mortgage Securities Fund will use short-term trading
to benefit from yield disparities among different issues of securities or
otherwise to achieve its investment objective. To the extent that the Mortgage
Securities Fund engages in short-term trading, such activities will cause it
to pay greater mark-up charges. The Mortgage Securities Fund's portfolio
turnover rate is set forth in "Financial Highlights."
 
INVESTMENT RISKS. The Mortgage Securities Fund is subject to interest rate
risk, which is the potential for a decline in bond prices due to rising
interest rates. In general, bond prices vary inversely with interest rates.
When interest rates rise, bond prices generally fall. Conversely, when
interest rates fall, bond prices generally rise. Interest rate risk applies to
U.S. Government securities as well as other bonds. U.S. Government securities
are guaranteed only as to the payment of interest and principal. The current
market prices for such securities are not guaranteed and will fluctuate.
 
  The Mortgage Securities Fund invests a significant portion of its assets in
mortgage-related securities and, as a result, is subject to prepayment risk.
Prepayment risk results because, as interest rates fall, homeowners are more
likely to refinance their home mortgages. When home mortgages are refinanced,
the principal on mortgage-related securities held is "prepaid" earlier than
expected. The Mortgage Securities Fund must then reinvest the unanticipated
principal payments, just at a time when interest rates on new mortgage
investments are falling. Prepayment risk has two important effects:
 
  . When interest rates fall and additional mortgage prepayments must be
    reinvested at lower interest rates, the income will be reduced; and
 
  . When interest rates fall, prices on mortgage-backed securities may not
    rise as much as comparable Treasury bonds because bond market investors
    may anticipate an increase in mortgage prepayments and a likely decline
    in income.
 
  The Mortgage Securities Fund's investments in mortgage-related securities
also subject it to extension risk. Extension risk is the possibility that
rising interest rates may cause prepayments to occur at a slower than expected
rate. This particular risk may effectively change a security which was
considered short- or intermediate-term at the time of purchase into a long-
term security. Long-term securities generally fluctuate more widely in
response to changes in interest rates than short- or intermediate-term
securities.

  The Mortgage Securities Fund's investments in mortgage-related securities
include derivative mortgage securities such as CMOs and stripped mortgage-
backed securities which, as discussed above, may involve risks in addition to
those found in other mortgage-related securities. Recent market experience has
shown that certain derivative mortgage securities may be highly sensitive to
changes in interest and prepayment rates and, as a result, the prices of such
securities may be highly volatile. In addition, recent market experience has
shown that during periods of rising interest rates, the market for certain
derivative mortgage securities may become more unstable and such securities
may become more difficult to sell as market makers either choose not to
repurchase such securities or offer prices, based on current market
conditions, which are unacceptable.
 
 
OHIO TAX-FREE FUND
 
  The objective of the Ohio Tax-Free Fund is to provide current income exempt
from federal income tax and Ohio personal income taxes. The Ohio Tax-Free Fund
will attempt to achieve its objective by investing in Ohio tax-exempt
securities. "Ohio tax-exempt securities" are debt obligations which (i) are
issued by or on behalf of the State of Ohio or its respective authorities,
agencies, instrumentalities and political subdivisions, and (ii) produce
interest which, in the opinion of bond counsel at the time of issuance, is
exempt from federal income tax and Ohio personal income taxes. As a matter of
fundamental policy, under normal market conditions at least 80% of the Ohio
Tax-Free Fund's net assets will be invested in Ohio tax-exempt securities. In
addition, the Ohio Tax-Free Fund will not, as a matter of fundamental policy,
invest in securities the income from which is treated as a preference item for
purposes of the federal alternative minimum tax. This policy will restrict the
Ohio Tax-Free Fund's ability to invest in certain private activity bonds
issued after August 7, 1986.
 
  The Ohio Tax-Free Fund will only invest in Ohio tax-exempt securities that
are rated at the time of purchase in one of the top four categories by an
NRSRO(s) or, if not rated, of comparable quality as determined by Huntington
under guidelines established by the Trustees. Based on current market
conditions, it is anticipated that the dollar-weighted average portfolio
maturity will be between four and seven years. Under normal market conditions,
the Ohio Tax-Free Fund will not invest in obligations with a remaining
maturity of more than 15 years at the time of purchase.
 
  The Ohio Tax-Free Fund may also invest in numerous types of short-term tax-
exempt instruments, which may be used to fund short-term cash requirements
such as interim financing in anticipation of the collections, revenue receipts
or bond sales to finance various public purposes.
 
  From time to time, the Ohio Tax-Free Fund may invest in obligations the
interest on which is subject to federal income tax or Ohio personal income
taxes pending investment in Ohio tax-exempt securities or for liquidity
purposes. The Ohio Tax-Free Fund may also hold a portion of its assets in cash
or money market instruments, the interest on which may not be exempt from
federal or Ohio personal income taxes.
 
  CREDIT ENHANCEMENT. Certain of the portfolio investments of the Ohio Tax-
Free Fund may have been credit enhanced by a guaranty, letter of credit or
insurance. The Ohio Tax-Free Fund typically evaluates the credit quality and
ratings of credit enhanced securities based upon the financial condition and
ratings of the party providing the credit enhancement (the "credit enhancer"),
rather than the issuer. However, credit enhanced securities will not be
treated as having been issued by the credit enhancer for diversification
purposes, unless the Ohio Tax-Free Fund has invested more than 10% of its
assets in securities issued, guaranteed or otherwise credit enhanced by the
credit enhancer, in which case the securities will be treated as having been
issued both by the issuer and the credit enhancer. The bankruptcy,
receivership or default of the credit enhancer will adversely affect the
quality and marketability of the underlying security.

FIXED INCOME SECURITIES FUND
 
  The objective of the Fixed Income Securities Fund is to achieve high current
income through investment in fixed income securities where the average
maturity of the Fixed Income Securities Fund will not exceed 10 years. The
Fixed Income Securities Fund may purchase obligations of the U.S. Government
and its agencies and instrumentalities, corporate bonds, debentures,
nonconvertible fixed income preferred stocks, mortgage pass-through
securities, eurodollar certificates of deposit and eurodollar bonds. The Fixed
Income Securities Fund may also invest up to 10% of its net assets in non-U.S.
dollar denominated bonds. Both fixed and variable rate issues may be
purchased. Debt securities will be rated at the time of purchase in one of the
top four categories by an NRSRO(s) or, if not rated, of comparable quality as
determined by Huntington under guidelines established by the Trustees. As a
matter of fundamental policy, under normal market conditions, the Fixed Income
Securities Fund will invest at least 65% of its assets in fixed income
securities. The Fixed Income Securities Fund may also, under normal market
conditions, invest a portion of its assets in cash equivalents, including
repurchase agreements and the shares of money market mutual funds, for
liquidity purposes.
 
        ADDITIONAL INFORMATION ON PORTFOLIO INVESTMENTS AND STRATEGIES
 
OHIO TAX-EXEMPT SECURITIES
 
  The two principal classifications of Ohio tax-exempt securities are general
obligation and limited obligation (or revenue) securities. General obligation
securities involve the credit of an issuer possessing taxing power and are
payable from the issuer's general unrestricted revenues. The characteristics
and methods of enforcement of general obligation securities vary according to
the law applicable to the particular issuer. Limited obligation securities are
payable only from the revenues derived from a particular facility or class of
facilities, or a specific revenue source, and generally are not payable from
the unrestricted revenues of the issuer. Private activity bonds and industrial
development bonds generally are limited obligation securities, the credit and
quality of which are usually directly related to the credit of the private
user of the facilities.
 
  The economy of Ohio, while diversifying more into the service area,
continues to rely in part on durable goods manufacturing, which is largely
concentrated in motor vehicles and equipment, steel, rubber products and
household appliances. As a result, general economic activity in Ohio, as in
many other industrially-developed states, tends to be more cyclical than in
some other states and in the nation as a whole. Agriculture also is an
important segment of the economy in the State, and the State has instituted
several programs to provide financial assistance to farmers. Ohio's economy,
including particularly an unemployment rate usually somewhat higher than the
national average, has had varying effects on the different geographic areas of
the State and the political subdivisions located in such geographic areas.
Although revenue obligations of the State or its political subdivisions may be
payable from a specific source or project, there can be no assurance that
future economic difficulties and the resulting impact on state and local
government finances will not adversely affect the market value of the Ohio
tax-exempt securities in an Ohio Fund, as defined below, or the ability of the
respective obligors to make timely payment of interest and principal on such
obligations. See the Statement of Additional Information for further
discussion of special considerations regarding investments in Ohio tax-exempt
securities.
 
                                      20

NON-DIVERSIFICATION
 
  The Ohio Municipal Money Market Fund and the Ohio Tax-Free Fund (the "Ohio
Funds") are non-diversified Funds under the 1940 Act, which means that they
may invest their assets in the obligations of fewer issuers than would be the
case if they were "diversified". The Ohio Funds' ability to invest a
relatively high percentage of their assets in the securities of a limited
number of issuers involves an increased risk of loss to an Ohio Fund if any
one issuer is unable to make interest or principal payments or if the market
value of the issuer's securities declines.
 
  Although non-diversified under the Investment Company Act, the Ohio Funds
intend to comply with Subchapter M of the Internal Revenue Code. This
undertaking requires that at the end of each quarter of the taxable year, with
regard to at least 50% of each Ohio Fund's total assets, no more than 5% of
its total assets are invested in the assets of a single issuer; beyond that,
no more than 25% of its total assets are invested in the securities of a
single issuer.
 
DEFENSIVE INVESTMENT STRATEGIES
 
  At times Huntington may judge that conditions in securities markets may make
pursuing a Fund's basic investment strategy inconsistent with the best
interests of the Fund's shareholders. At such times, Huntington may
temporarily use alternative strategies, primarily designed to reduce
fluctuations in the value of a Fund's assets. In implementing these temporary
"defensive" strategies, a Fund may temporarily place all or a portion of its
assets in cash, U.S. Government securities, debt securities which Huntington
considers to be of comparable quality to the acceptable investments of the
Fund and other investments which Huntington considers consistent with such
strategies. In the case of the Ohio Funds, a Fund's alternative strategies may
give rise to income which is not exempt from federal or state taxes.
 
OPTIONS AND FUTURES CONTRACTS (ALL FUNDS OTHER THAN THE MONEY MARKET FUNDS)
 
  A Fund may seek to increase its current return by writing covered call
options and covered put options on its portfolio securities or other
securities in which it may invest. A Fund receives a premium from writing a
call or put option, which increases a Fund's return if the option expires
unexercised or is closed out at a net profit. A Fund may also buy and sell put
and call options on its securities for hedging purposes. When a Fund writes a
call option on a portfolio security, it gives up the opportunity to profit
from any increases in the price of the security above the exercise price of
the option. When it writes a put option, a Fund takes the risk that it will be
required to purchase a security from the option holder at a price above the
current market price of the security. A Fund may terminate an option that it
has written prior to expiration by entering into a closing purchase
transaction in which it purchases an option having the same terms as the
option written.
 
  A Fund may purchase and sell futures contracts and related options to hedge
against changes in the value of securities it owns or expects to purchase.
Futures contracts on a variety of stock and bond indices are currently
available. An index is intended to represent a numerical measure of market
performance by the securities making up the index. A Fund may purchase and
sell futures contracts on any index approved for trading by the Commodity
Futures Trading Commission to hedge against general changes in market values
of securities which a Fund owns or expects to purchase. A Fund may also
purchase and sell put and call options on index futures or directly on the
underlying indices for hedging purposes. In addition, a Fund may purchase and
sell futures contracts and related options on individual debt securities which
a Fund owns or expects to purchase, if and when such futures contracts and
options become available.
 
                                      21
<PAGE>
 
 
  In connection with its futures transactions, a Fund will be required to
deposit as "initial margin" an amount of cash and/or securities. Thereafter,
subsequent payments (referred to as "variation margin") are made to and from
the broker to reflect changes in the value of the futures contract. A Fund
will not generally purchase or sell futures contracts or purchase or sell
options on futures contracts if as a result the sum of initial margin deposits
on a Fund's existing futures contracts and options written by a Fund plus
premiums paid for outstanding options on futures contracts purchased by a
Fund, would exceed 5% of a Fund's net assets.
 
  Options and futures transactions involve various risks, including the risk
that a Fund may be unable at times to close out its positions, that such
transactions may not accomplish their purposes because of imperfect market
correlations, or that Huntington or its Subadviser may not forecast market
movements correctly. Options and futures transactions involve costs and may
result in losses. The effective use of options and futures strategies by a
Fund is dependent upon, among other things, a Fund's ability to terminate
options and futures positions at times when Huntington or its Subadviser deems
it desirable to do so. Although a Fund will enter into an options or futures
contract position only if Huntington or its Subadviser believes that a liquid
secondary market exists for such options or futures contract, there is no
assurance that a Fund will be able to effect closing transactions at a
particular time or at an acceptable price.
 
  The Funds generally expect that their options and futures transactions will
be conducted on recognized exchanges. In certain instances, however, a Fund
may purchase and sell options in the over-the-counter ("OTC") markets. A
Fund's ability to terminate options in the OTC market may be more limited than
for exchange-traded options and may also involve the risk that securities
dealers participating in such transactions would be unable to meet their
obligations to a Fund. A Fund will, however, engage in OTC market transactions
only when appropriate exchange-traded transactions are unavailable and when,
in the opinion of Huntington, the pricing mechanism and liquidity of the OTC
market is satisfactory and the participants are responsible parties likely to
meet their contractual obligations.
 
  The use of options and futures strategies also involves the risk of
imperfect correlation between movements in the prices of options and futures
contracts and movements in the value of the underlying securities that are the
subject of a hedge. The successful use of these strategies further depends on
the ability of Huntington to forecast market movements correctly.
 
  For more information about any of the options or futures portfolio
transactions described above, see the Statement of Additional Information.
 
FOREIGN INVESTMENTS
 
  Except as otherwise limited in this Prospectus, a Fund may invest some or
all of its assets in securities principally traded in foreign markets. Since
foreign securities are normally denominated and traded in foreign currencies,
the value of a Fund's assets may be affected favorably or unfavorably by
currency exchange rates and exchange control regulation. Exchange rates with
respect to certain currencies may be particularly volatile. There may be less
information publicly available about a foreign company than about a U.S.
company, and foreign companies are not generally subject to accounting,
auditing, and financial reporting standards and practices comparable to those
in the United States. The securities of some foreign companies are less liquid
and at times more volatile than securities of comparable U.S. companies.
Foreign brokerage commissions and other fees are also generally higher than in
the United States. Foreign settlement procedures and trade regulations may
involve certain risks (such as delays in payment or delivery of securities or
in the recovery of a Fund's assets held abroad) and expenses not present in
the settlement of domestic investments.
 
  In addition, with respect to certain foreign countries, there is a
possibility of nationalization or expropriation of assets, confiscatory
taxation, political or financial instability and diplomatic
 
                                      22
<PAGE>
 
developments which could affect the value of investments in those countries.
In certain countries, legal remedies available to investors may be more
limited than those available with respect to investments in the United States
or other countries. The laws of some foreign countries may limit a Fund's
ability to invest in securities of certain issuers located in those countries.
Special tax considerations apply to foreign securities.
 
  A Fund may buy or sell foreign currencies and forward foreign currency
exchange contracts for hedging purposes in connection with its foreign
investments.
 
  A more detailed explanation of foreign investments, and the risks associated
with them, is included in the Statement of Additional Information.
 
REPURCHASE AGREEMENTS
 
  Certain securities in which a Fund invests may be purchased pursuant to
repurchase agreements. Repurchase agreements are arrangements in which banks,
broker/dealers, and other recognized financial institutions sell U.S.
Government securities or other securities to a Fund and agree at the time of
sale to repurchase them at a mutually agreed upon time and price. A Fund or
its custodian will take possession of the securities subject to repurchase
agreements and these securities will be marked to market daily. To the extent
that the original seller does not repurchase the securities from a Fund, a
Fund could receive less than the repurchase price on any sale of such
securities. In the event that such a defaulting seller filed for bankruptcy or
became insolvent, disposition of such securities by a Fund might be delayed
pending court action. The Trustees believe that under the regular procedures
normally in effect for custody of a Fund's portfolio securities subject to
repurchase agreements, a court of competent jurisdiction would rule in favor
of a Fund and allow retention or disposition of such securities. A Fund will
only enter into repurchase agreements with banks and other recognized
financial institutions, such as broker/dealers, which are found by Huntington
to be creditworthy pursuant to guidelines established by the Trustees.
 
WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS
 
  A Fund may purchase securities on a when-issued or delayed delivery basis.
These transactions are arrangements in which a Fund purchases securities with
payment and delivery scheduled for a future time. The seller's failure to
complete these transactions may cause a Fund to miss a price or yield
considered to be advantageous. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices. Accordingly, a Fund may pay more
or less than the market value of the securities on the settlement date.
 
  A Fund may dispose of a commitment prior to settlement if the Fund's adviser
deems it appropriate to do so.
 
  In connection with its ability to purchase securities on a when-issued or
delayed delivery basis, the Mortgage Securities Fund may enter into mortgage
"dollar rolls" in which it sells securities for delivery in the current month
and simultaneously contracts with the same counterparty to repurchase similar
(same type, coupon and maturity) but not identical securities on a specified
future date. The Mortgage Securities Fund gives up the right to receive
principal and interest paid on the securities sold. However, the Mortgage
Securities Fund would benefit to the extent of any difference between the
price received for the securities sold and the lower forward price for the
future purchase plus any fee income
 
                                      23
<PAGE>
 
received. Unless such benefits exceed the income, capital appreciation and
gain or loss due to mortgage prepayments that would have been realized on the
securities sold as part of the mortgage dollar roll, the use of this technique
will diminish the investment performance of the Mortgage Securities Fund
compared with what such performance would have been without the use of
mortgage dollar rolls. The Mortgage Securities Fund will hold and maintain in
a segregated account until the settlement date, cash or liquid high-grade debt
securities in an amount equal to the forward purchase price. The benefits
derived from the use of mortgage dollar rolls may depend upon Piper's ability
to predict correctly mortgage prepayments and interest rates. There is no
assurance that mortgage dollar rolls can be successfully employed. In
addition, the use of mortgage dollar rolls by the Mortgage Securities Fund
while remaining substantially fully invested increases the amount of its
assets that are subject to market risk to an amount that is greater than its
net asset value, which could result in increased volatility of the price of
its shares. The Mortgage Securities Fund may invest up to 35% of its total
assets in securities purchased on a when-issued or delayed delivery basis.
 
LENDING OF PORTFOLIO SECURITIES
 
  In order to generate additional income, a Fund may lend its portfolio
securities on a short-term basis to brokers, dealers or other financial
institutions. A Fund will only enter into loan arrangements with brokers,
dealers or other financial institutions which Huntington has determined are
creditworthy under guidelines established by the Trustees and must receive
collateral equal to at least 102% of the current market value of the
securities loaned. The collateral received when a Fund lends portfolio
securities must be valued daily and, should the market value of the loaned
securities increase, the borrower must furnish additional collateral to the
Fund. As a matter of fundamental policy, the aggregate value of all securities
loaned by a Fund may not exceed 20% of the Fund's total assets.
 
  There is the risk that, when lending portfolio securities, the securities
may not be available to a Fund on a timely basis and a Fund may, therefore,
lose the opportunity to sell the securities at a desirable price. In addition,
in the event that a borrower of securities would file for bankruptcy or become
insolvent, disposition of the securities may be delayed pending court action.
 
                            INVESTMENT RESTRICTIONS
 
  Each Fund has adopted certain investment restrictions and limitations for
the purpose of reducing its exposure in specific situations. These investment
limitations are fundamental policies and may be changed with respect to any
Fund only by a vote of a majority of the outstanding shares of that Fund.
 
  No Fund will:
 
  (1)  Except for the Ohio Funds, invest more than 5% of the value of its
       total assets in the securities of any one issuer (this limitation does
       not apply to securities issued or guaranteed by the U.S. Government or
       any of its agencies or instrumentalities or to repurchase agreements
       secured by such obligations);
 
  (2)  Invest 25% or more of the value of its total assets (i) in securities
       of companies primarily engaged in any one industry (other than the U.S.
       Government, its agencies and instrumentalities), and (ii) with respect
       to the Ohio Funds, in municipal obligations of one issuer or which are
       related in such a way that, in the opinion of Huntington, an economic,
       business or political development other than an Ohio state-wide,
       national or international development, affecting one such obligation
       would also affect the others in a similar manner. Such concentration
       may occur as a result of changes in the market value of portfolio
       securities, but such concentration may not result from investment;
 
 
                                      24
<PAGE>
 
  (3)  Except for investments by the Money Market Fund in commercial paper
       issued under Section 4(2) of the Securities Act of 1933 and certain
       other restricted securities which meet the criteria for liquidity as
       established by the Trustees, invest more than 10% of the value of its
       total assets in illiquid securities, including restricted securities,
       repurchase agreements of over seven days' duration and OTC options; and
 
  (4)  Borrow in excess of 5% of its total assets (borrowings are permitted
       only as a temporary measure for extraordinary or emergency purposes) or
       pledge (mortgage) its assets as security for any indebtedness.
 
                       HOW THE FUNDS VALUE THEIR SHARES
 
  Each Money Market Fund attempts to stabilize the net asset value of its
Investment Shares at $1.00 by valuing its portfolio securities using the
amortized cost method. The net asset value per Investment Share is determined
by adding the interest of the Investment Shares in the value of all securities
and other assets of a Money Market Fund, subtracting the interest of the
Investment Shares in the liabilities of a Fund and those attributable to
Investment Shares, and dividing the remainder by the total number of
Investment Shares outstanding. A Money Market Fund cannot guarantee that its
net asset value will always remain at $1.00 per share.
 
 
  The net asset value for Investment Shares of each of the other Funds is
determined by adding the interest of the Investment Shares in the market value
of all securities and other assets of a Fund, subtracting the interest of the
Investment Shares in the liabilities of a Fund and those attributable to
Investment Shares, and dividing the remainder by the total number of
Investment Shares outstanding. The net asset value of a Fund's Investment
Shares will differ from that of Trust Shares due to the expense of the Rule
12b-1 fee applicable to a Fund's Investment Shares.
 
  Securities for which market quotations are readily available are stated at
market value. Short-term investments with remaining maturities of 60 days or
less at the time of purchase are stated at amortized cost, which approximates
market value. Debt securities for which market quotations are not readily
available will be valued on the basis of valuations provided by pricing
services approved by the Trustees. Pricing services often use information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities, and various relationships between
securities in determining value. All other Fund assets are valued at their
fair value following procedures approved by the Trustees.
 
  The Money Market Funds calculate net asset value per Investment Share as of
the close of the New York Stock Exchange (currently 4:00 p.m. Eastern Time) on
each Business Day. The other Funds calculate net asset value per Investment
Share as of the close of the New York Stock Exchange (currently 4:00 p.m.
Eastern Time) on each Business Day. As used herein, a "Business Day"
constitutes Monday through Friday except (i) days on which there are not
sufficient changes in the value of a Fund's portfolio securities that its net
asset value might be materially affected; (ii) days during which no shares are
tendered for redemption and no orders to purchase shares are received; and
(iii) the following holidays: New Year's Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas
Day.
 
                         HOW TO BUY INVESTMENT SHARES
 
  Investment Shares of the Funds may be purchased through The Huntington
Investment Company, Huntington Personal Bankers or the Mutual Fund Services
Center (collectively, the "Huntington
 
                                      25
<PAGE>
 
Group") pursuant to respective agreements between The Huntington Investment
Company or The Huntington Trust Company, N.A. and the Distributor. Investors
may purchase Investment Shares of the Funds on all Business Days. Investment
Shares in each Money Market Fund other than the Ohio Municipal Money Market
Fund purchased prior to 11:30 a.m. (Eastern Time) begin earning dividends that
day; Investment Shares in the Ohio Municipal Money Market Fund purchased prior
to 10:30 a.m. (Eastern Time) begin earning dividends that day; Investment
Shares purchased after such time begin earning dividends on the following day.
In connection with the sale of a Fund's Investment Shares, the Distributor may
from time to time offer certain items of nominal value to any shareholder.
 
  From time to time, the Trust may temporarily suspend the offering of shares
of one or more of the Funds or any class thereof. During the period of any
such suspension and depending on the reasons for the suspension, persons who
are already shareholders of any such Fund or class may be permitted to
continue to purchase additional shares and to have dividends reinvested. The
Trust or the Distributor may refuse any order to purchase shares or waive any
minimum purchase requirements. The Funds will issue certificates representing
Investment Shares upon request.
 
TO PLACE AN ORDER
 
  To purchase Investment Shares of the Funds, an investor may call The
Huntington Investment Company at 800-322-4600, or the investor's Personal
Banker directly. All other investors should call the Mutual Fund Services
Center at (in Ohio) 614-480-5580 or (outside the 614 Area Code) 800-253-0412.
 
  Payment may be made either by check or wire transfer of federal funds. To
purchase by check, the check must be included with the order and made payable
to the name of the applicable Fund, designating Investment Shares. If a
shareholder pays for Investment Shares by check and the check does not clear,
the purchase will be cancelled, and the shareholder may be charged a fee and
will be liable for any losses incurred. Neither initial nor subsequent
investments will be made by third party check. Orders are considered received
after payment by check is converted into federal funds by the Funds' transfer
agent, SEI Financial Management Corporation (the "Transfer Agent").
 
  When payment is made through wire transfer of federal funds, the order is
considered received immediately upon receipt by the Transfer Agent. With
respect to the Money Market Fund, Ohio Municipal Money Market Fund and U.S.
Treasury Money Market Fund, payment by wire must be received by the applicable
member of the Huntington Group before 10:30 a.m. (Eastern Time) in order to
earn dividends for that day. With respect to the Growth Fund, Mortgage
Securities Fund, Ohio Tax-Free Fund and Fixed Income Securities Fund, payment
by wire must be received by the applicable member of the Huntington Group
before 4:00 p.m. (Eastern Time) in order for Investment Shares of a Fund to be
purchased at that day's price. Prior to purchasing by wire, investors should
call the applicable member of the Huntington Group. It is the responsibility
of the applicable member of the Huntington Group to transmit orders promptly
to the Transfer Agent. Federal funds should be wired as follows: Huntington
National Bank, ABA 044000024, Trust Department, Account Number 01891160404,
Monitor Retail, Attention: Shareholder Services.
 
MINIMUM INVESTMENT REQUIRED
 
  The minimum initial investment in Investment Shares of a Fund is $1,000.
Subsequent investments must be in amounts of at least $50.

  Purchases at Net Asset Value. Investment Shares issued through reinvestment
of dividends and capital gains distributions are not subject to a sales
charge. In addition, Investment Shares of a Fund may be purchased at net asset
value, without a sales charge, by officers, directors, employees (and their
spouses and family members) and retirees of Huntington Bancshares Incorporated
and its subsidiaries.
 
  Dealer Concession. For sales of Investment Shares of the Funds, a dealer
will normally receive up to 90% of the applicable sales charge. Any portion of
the sales charge which is not paid to a dealer will be retained by the
Distributor. However, the Distributor will, periodically, uniformly offer to
pay cash, or promotional incentives in the form of trips to sales seminars at
luxury resorts, tickets or other items, to all dealers selling Investment
Shares of the Funds, from that portion of the sales load which the Distributor
retains or any other source available to it. Such payments will be predicated
upon the amount of Investment Shares of the Funds that are sold by the dealer.
 
  The sales charge for Investment Shares sold other than through registered
broker/dealers will be retained by the Distributor. The Distributor may pay
fees to banks out of the sales charge in exchange
 
                                      27
<PAGE>
 
for sales and/or administrative services performed on behalf of the banks'
customers in connection with the initiation of customer accounts and purchases
of Investment Shares of the Funds.
 
  Reducing the Sales Charge. The sales charge can be reduced through:
 
  . quantity discounts and accumulated purchases;
 
  . signing a 13-month letter of intent;
 
  . using the reinstatement privilege; or
 
  . concurrent purchases.
 
  Quantity Discounts and Accumulated Purchases. As shown in the table above,
larger purchases reduce the sales charge paid. The Distributor will combine
purchases made on the same day by the investor, his spouse, and his children
under age 21 when it calculates the sales charge. In addition, the sales
charge, if applicable, is reduced for purchases made at one time by a trustee
or fiduciary for a single trust estate or a single fiduciary account.
 
  If an additional purchase of Investment Shares in a Fund which impose a
sales charge is made, the Distributor will aggregate such additional purchases
with previous purchases of Investment Shares of Funds imposing a sales charge
provided the prior purchase is still invested in the Funds. For example, if a
shareholder already owns Investment Shares having a current value at the
public offering price of $700,000 and he purchases $50,000 more at the current
public offering price, the sales charge on the additional purchase according
to the schedule now in effect would be 0.75%, not 1.5%.
 
  To receive the sales charge reduction, an investor should complete the
appropriate section of the account application at the time the purchase is
made indicating that Investment Shares of Funds which impose a sales charge
have been purchased and are still invested or that such purchases are being
combined. The Distributor will reduce the sales charge after it confirms the
purchase.
 
  Letter of Intent. If an investor intends to purchase at least $100,000 of
Investment Shares in a Fund that imposes a 4% sales charge or at least
$500,000 in one or more Funds that imposes a 2% sales charge, over the next 13
months, the sales charge may be reduced by completing the Letter of Intent
section of the account application. The Letter of Intent includes a provision
for a sales charge adjustment depending on the amount actually purchased
within the 13-month period. In addition, pursuant to a Letter of Intent, the
custodian will hold in escrow the difference between the sales charge
applicable to the amount initially purchased and the sales charge paid at the
time of the investment, which is based on the amount covered by the Letter of
Intent.
 
  For example, assume an investor signs a Letter of Intent to purchase at
least $250,000 in Investment Shares of a Fund that imposes a 4% sales charge
and, at the time of signing the Letter of Intent, purchases $100,000 of
Investment Shares of one of these Funds. The investor would pay an initial
sales charge of 2.50% (the sales charge applicable to purchases of $250,000),
and 1.00% of the investment (representing the difference between the 3.50%
sales charge applicable to purchases of $100,000 and the 2.50% in sales
charges already paid) would be held in escrow until the investor has purchased
the remaining $150,000 or more of Investment Shares under his Letter of
Intent.
 
  The amount held in escrow will be applied to the investor's account at the
end of the 13-month period unless the amount specified in the Letter of Intent
is not purchased. In order to qualify for a Letter of Intent, the investor
will be required to make a minimum initial investment of at least $25,000.
 
 
                                      28
<PAGE>
 
  A Letter of Intent will not obligate the investor to purchase Investment
Shares, but if he does, each purchase during the period will be at the sales
charge applicable to the total amount intended to be purchased. The Letter of
Intent may be dated as of a prior date to include any purchases made within
the past 90 days.
 
  Reinstatement Privilege. If Investment Shares in a Fund have been redeemed,
the shareholder has a one-time right, within 30 days of redemption, to
reinvest the redemption proceeds at the next-determined net asset value
without any sales charge. The applicable member of the Huntington Group must
be notified in writing of the reinvestment by the shareholder in order to
eliminate a sales charge. If the shareholder redeems his Investment Shares in
a Fund and utilizes the reinstatement privilege, there may be tax
consequences.
 
  Concurrent Purchases.  For purposes of qualifying for a sales charge
reduction, a shareholder has the privilege of combining concurrent purchases
of Investment Shares in two or more Funds in the Trust, the public offering
price of which includes a sales charge. For example, if a shareholder of the
Growth Fund concurrently invests $30,000 in one Fund with a sales charge, and
$70,000 in another Fund with a sales charge, the sales charge will be reduced.
In addition, if a shareholder of the Mortgage Securities Fund, Ohio Tax-Free
Fund or Fixed Income Securities Fund concurrently invests $50,000 in one Fund
with a sales charge, and $450,000 in another Fund with a sales charge, the
sales charge will be reduced.
 
  To receive this sales charge reduction, the applicable Huntington Group
member must be notified in writing by the shareholder (at the address provided
below under "How to Exchange Investment Shares Among the Funds--By Mail") at
the time the concurrent purchases are made. The Distributor will reduce the
sales charge after it confirms the purchases.
 
SYSTEMATIC INVESTMENT PROGRAM
 
  Once an account has been opened, holders of Investment Shares of a Fund may
add to their investment on a regular basis in minimum amounts of at least $50.
Under this program, funds will be automatically withdrawn periodically from
the shareholder's checking account and invested in Investment Shares of a Fund
at the applicable public offering price per share next determined after an
order is received by the Transfer Agent. Shareholders may apply for
participation in this program by completing the appropriate section of the
account application.
 
               HOW TO EXCHANGE INVESTMENT SHARES AMONG THE FUNDS
 
  Shareholders may exchange Investment Shares in any Fund for Investment
Shares in any other Fund offering Investment Shares at the respective net
asset values per Investment Share next determined after receipt of the request
in good order, plus the applicable sales charge (if any) as described below.
This privilege is available to shareholders resident in any state in which the
Fund shares being acquired may be sold.
 
  No sales charge applies when Investment Shares are exchanged from a Fund
that imposes such a charge to a Fund with no sales charge. If, however, a
shareholder seeks to exchange shares of a Fund that does not have a sales
charge for shares of a Fund that imposes such a charge, the shareholder will
be required to pay the applicable sales charge of the Fund into which the
shares are exchanged. In all cases, shareholders will be required to pay a
sales charge only once. Thus, for example, no sales charge applies when shares
are exchanged among Funds that impose a sales charge. Similarly, no sales
charge applies where a shareholder exchanges shares of a Fund with a
 
                                      29
<PAGE>
 
sales charge for shares of a Fund that does not impose such a charge and
subsequently exchanges those shares back into a Fund with a sales charge.
 
  In order to make an exchange, shareholders will be required to maintain the
applicable minimum account balance in each Fund in which shares are owned and
must satisfy the minimum initial and subsequent purchase amounts of the Fund
into which shares are exchanged.
 
  If the exchanging shareholder does not have an account in the Fund whose
Investment Shares are being acquired, a new account will be established with
the same registration and reinvestment options for dividends and capital gains
distributions as the account of the Fund from which the Investment Shares are
exchanged, unless otherwise specified in writing by the shareholder. In the
event the new account registration is not identical to that of the existing
account, a signature guarantee will be required. (See "Redeeming By Mail"
below.)
 
  An exchange is treated as a sale for federal income tax purposes and,
depending on the circumstances, a short or long-term capital gain or loss may
be realized. In addition, if a shareholder exchanges shares of a Fund that
imposes a sales charge into another Fund that imposes such a charge, there may
be special tax consequences.
 
  The Trust's exchange privileges may be terminated or modified. Except as
indicated below, shareholders will be given 60 days' prior notice of any such
termination or any material amendment of existing exchange privileges. No
notice will be given when the only material effect of an amendment is to
reduce or eliminate any charges payable at the time of an exchange or under
certain extraordinary circumstances, such as in connection with the suspension
of the sale or redemption of Fund shares. Shareholders may obtain further
information on the exchange privilege by calling the applicable member of the
Huntington Group.
 
BY TELEPHONE
 
  Shareholders may provide instructions for exchanges between Funds by
calling: The Huntington Investment Company at 800-322-4600; their Personal
Banker directly or Mutual Fund Services Center at (in Ohio) 614-480-5580 or
(outside the 614 Area Code) 800-253-0412. Investors may request the Trust's
telephone exchange privilege on their account application. Information on this
service can be obtained through the applicable member of the Huntington Group.
 
  Investment Shares may be exchanged by telephone only between Fund accounts
having identical shareholder registrations. Exchange instructions given by
telephone may be electronically recorded and will be binding upon the
shareholder. Because telephone exchange requests will be honored from anyone
who provides the correct information (described below under "By Mail"), this
service involves a possible risk of loss if someone uses the service without
the shareholder's permission.
 
  Telephone exchange instructions must be received by the applicable member of
the Huntington Group before 3:00 p.m. (Eastern Time) for Investment Shares to
be exchanged the same day. The telephone exchange privilege may be modified or
terminated at any time and shareholders will be notified of any such
modification or termination. Shareholders of a Fund may have difficulty in
making exchanges by telephone during times of extreme economic or market
conditions. If a shareholder cannot make contact by telephone, it is
recommended that an exchange request be made in writing and sent by overnight
mail to the appropriate member of the Huntington Group. Written instructions
may require a signature guarantee. If reasonable procedures are not followed
by the Funds, they may be liable for losses due to unauthorized or fraudulent
telephone instructions.
 
 
                                      30
<PAGE>
 
BY MAIL
 
  Shareholders may provide instructions for exchanges between the Funds by
making a written request to the appropriate member of the Huntington Group at
Huntington Center, 41 South High Street, Columbus, Ohio 43287.
 
  To exchange by letter or by telephone, a shareholder must state (1) the name
of the Fund from which the exchange is to be made (and designating that
Investment Shares are involved), (2) the name(s) and address on the
shareholder account, (3) the account number, (4) the dollar amount or number
of Investment Shares to be exchanged, and (5) the Fund into which the
Investment Shares are to be exchanged. Written exchange requests must be
signed by the shareholder, and it may be necessary to have the shareholder's
signature guaranteed by a member firm of a national securities exchange or by
a commercial bank, savings and loan association or trust company. Further
documentation may be required, and a signature guarantee is generally required
from corporations, executors, administrators, trustees and guardians.
 
                        HOW TO REDEEM INVESTMENT SHARES
 
  Shareholders may redeem all or any portion of the Investment Shares in their
account on any Business Day at the appropriate net asset value per share next
determined after a redemption request in proper form is received by the
Transfer Agent. Under unusual circumstances, a Fund may suspend redemptions or
postpone payment for more than seven days, as permitted by federal securities
law.
 
REDEEMING BY TELEPHONE
 
  A shareholder may redeem Investment Shares of a Fund by calling The
Huntington Investment Company at 800-322-4600, their Personal Banker directly
or the Mutual Fund Services Center at (in Ohio) 614-480-5580 or (outside the
614 Area Code) 800-253-0412.
 
  Shareholders of the Money Market Fund, Ohio Municipal Money Market Fund, and
U.S. Treasury Money Market Fund who request a redemption before 10:30 a.m.
(Eastern Time) will usually have the proceeds wired the same day but will not
be entitled to that day's dividend; redemption requests received after 10:30
a.m. (Eastern Time) will receive that day's dividend and the proceeds will
normally be wired the following Business Day. Requests for redemptions in the
Income and Equity Funds must be received by the appropriate member of the
Huntington Group before 3:00 p.m. (Eastern Time) in order for Investment
Shares to be redeemed at that day's net asset value.
 
  Members of the Huntington Group are responsible for promptly submitting
redemption requests and providing proper written redemption instructions to a
Fund. If at anytime the Trust shall determine it necessary to terminate or
modify this method of redemption, shareholders will be promptly notified.
 
  Investors may request the Trust's telephone redemption privilege on their
account application. If not completed at the time of initial application,
authorization forms and information on this service can be obtained through
the members of the Huntington Group. Proceeds for redemptions will normally be
wired to the shareholder's account with proper authorization (at a domestic
commercial bank that is a member of the Federal Reserve System designated by
the shareholder in writing) or a check will be sent to the address of record.
Telephone redemption instructions may be recorded.
 
  In the event of extreme economic or market conditions, a shareholder may
experience difficulty in redeeming by telephone. If such a case should occur,
another method of redemption, such as through written request, should be
considered. If reasonable procedures are not followed by the Funds, they may
be liable for losses due to unauthorized or fraudulent telephone instructions.
 
                                      31
<PAGE>
 
 
REDEEMING BY MAIL
 
  Shareholders may redeem Investment Shares of a Fund by sending a written
request to the appropriate member of the Huntington Group. The written request
should include the shareholder's name, Fund name (designating Investment
Shares), the account number, and the Investment Share or dollar amount
requested.
 
  Shareholders requesting a redemption of $50,000 or more, a redemption of any
amount to be sent to an address other than that on record with the Transfer
Agent, or a redemption payable other than to the shareholder of record must
have signatures on written redemption requests guaranteed by:
 
  --a trust company or commercial bank whose deposits are insured by the Bank
      Insurance Fund ("BIF"), which is administered by the FDIC;
 
  --a member of the New York, American, Midwest, or Pacific Stock Exchanges;
 
  --a savings bank or savings and loan association whose deposits are insured
      by the Savings Association Insurance Fund ("SAIF"), which is
      administered by the FDIC; or
 
  --  any other "eligible guarantor institution," as defined in the Securities
      Exchange Act of 1934.
 
  The Funds do not accept signatures guaranteed by a notary public.
 
  The Funds and the Transfer Agent have adopted standards for accepting
signature guarantees from the above institutions. The Funds may elect in the
future to limit eligible signature guarantors to institutions that are members
of a signature guarantee program. The Funds and the Transfer Agent reserve the
right to amend these standards at any time without notice.
 
  Normally, a check for the proceeds is mailed to the shareholder within one
business day, but in no event more than seven days, after receipt of a proper
written redemption request provided that Huntington has received payment for
Investment Shares from the shareholder. Shares will be redeemed at the net
asset value determined as of the end of the Business Day on which the written
redemption request is received by the Transfer Agent.
 
REDEEMING BY CHECK (MONEY MARKET FUNDS ONLY)
 
  At the shareholder's request, the appropriate member of the Huntington Group
will establish a checking account for redeeming Investment Shares of the Money
Market Funds. Shareholders may be charged a fee for this service.
 
  With a Fund checking account, Investment Shares may be redeemed simply by
writing a check for $250 or more. The redemption will be made at the
applicable net asset value per share on the date that the check is presented
to the Fund. A check may not be written to close an account. In addition, if a
shareholder wishes to redeem Investment Shares and have the proceeds
available, a check may be written and negotiated through the shareholder's
local bank. Checks should never be sent to the issuing bank to redeem
Investment Shares. Cancelled checks are sent to the shareholder each month.
 
REDEEMING BY FAX
 
  Shareholders wishing to expedite the redemption process may Fax a copy of
their written request to the appropriate member of the Huntington Group at Fax
No. 614-480-4682 (The Huntington Investment Company) or 614-480-5516 (Mutual
Fund Services Center). Shareholders redeeming by Fax must call the appropriate
member of the Huntington Group to confirm receipt of the written request. See
"Redeeming By Telephone" in this Prospectus for a discussion of when
shareholders will receive redemption proceeds when redeeming by Fax.

                         SYSTEMATIC WITHDRAWAL PROGRAM
 
  Shareholders who desire to receive payments of a predetermined amount may
take advantage of the Systematic Withdrawal Program. Under this program,
Investment Shares of a particular Fund are redeemed at the applicable net
asset value per Investment Share at the time of the withdrawal to provide for
periodic withdrawal payments in an amount directed by the shareholder.
Depending upon the amount of the withdrawal payments, the amount of dividends
paid and capital gains distributions with respect to Investment Shares, and
the fluctuation of the net asset value of Investment Shares redeemed under
this program, redemptions may reduce, and eventually deplete, the
shareholder's investment in Investment Shares of a particular Fund. For this
reason, payments under this program should not be considered as yield or
income on the shareholder's investment in Investment Shares of a Fund. To be
eligible to participate in this program, a shareholder must have an account
value of at least $10,000. A shareholder may apply for participation in this
program through the appropriate member of the Huntington Group. The Trust
requires two to three days to process a systematic withdrawal and uses
automated clearing house funds, which are transferred electronically and thus
have the potential to be uninvested for up to 48 hours.
 
                          ACCOUNTS WITH LOW BALANCES
 
  Due to the high cost of maintaining accounts with low balances, a Fund may
redeem Investment Shares in any account, except retirement plans, and pay the
proceeds to the shareholder if the account balance falls below the required
minimum value of $1,000 due to shareholder redemptions. This requirement does
not apply, however, if the balance falls below $1,000 because of changes in a
Fund's net asset value. Before Investment Shares are redeemed to close an
account, the shareholder will be notified in writing and allowed 30 days to
purchase additional Investment Shares to meet the minimum requirement.
 
                            MANAGEMENT OF THE TRUST
 
  The Trustees of the Trust are responsible for generally overseeing the
conduct of each Fund's business. The Huntington Trust Company, N.A.
("Huntington"), Huntington Center, 41 South High Street, Columbus, Ohio 43287,
serves as investment adviser to the Funds pursuant to an investment advisory
agreement with the Trust. Huntington is an indirect wholly-owned subsidiary of
Huntington Bancshares Incorporated, a registered bank holding company with
executive offices located at Huntington Center, 41 South High Street,
Columbus, Ohio 43287.
 
  Subject to the supervision of the Trustees, Huntington provides a continuous
investment program for the Funds, including investment research and management
with respect to all securities, instruments, cash and cash equivalents in the
Funds. The Trust pays Huntington management fees, computed daily and payable
monthly, for each of the Funds at the following annual rates: Money Market
Fund and Ohio Municipal Money Market Fund: .30% of the first $500 million of
average daily net assets of the Fund, .25% of the next $500 million, and .20%
of any amount over $1 billion; U.S. Treasury Money Market Fund: .20% of the
Fund's average daily net assets; Growth Fund: .60% of the Fund's average daily
net assets; and Mortgage Securities Fund, Ohio Tax-Free Fund and Fixed Income
Securities Fund: .50% of the Fund's average daily net assets. Huntington may
periodically waive all or a portion of its management fee with respect to any
Fund to increase the net income of the Fund available for distribution as
dividends.

securities for the Funds.

and Piper, Piper will assist Huntington in the purchase or sale of the
Mortgage Securities Fund's portfolio instruments. Huntington pays Piper

assets.

DISTRIBUTION OF INVESTMENT SHARES
 
  SEI Financial Services Company, 680 East Swedesford Road, Wayne,
Pennsylvania 19087, is the principal distributor for shares of each Fund. It
is a Delaware corporation, and is the principal distributor for a number of
investment companies.
 
DISTRIBUTION PLANS
 
  Each Fund offering Investment Shares has adopted a Distribution Plan
pursuant to Rule 12b-1 under the 1940 Act (the "Distribution Plan"). The
Distribution Plan provides for payments to be made to the Distributor in
connection with the provision of certain services (described below) with
respect to the Funds' Investment Shares.
 
  In accordance with the Distribution Plan, the Distributor may enter into
agreements with brokers and dealers relating to distribution and/or
administrative services with respect to the Investment Shares of the Funds.
The Distributor may also enter into agreements with administrators (including
financial institutions, fiduciaries, custodians for public funds, and
investment advisers) to provide administrative services with respect to
Investment Shares. Administrative services may include, but are not limited
to, the following functions: providing office space, equipment, telephone
facilities, and various clerical, supervisory, computer, and other personnel
as necessary or beneficial to establish and maintain shareholder accounts and
records; processing purchase and redemption transactions and automatic
investments of customer account cash balances; answering routine customer
inquiries regarding
 
                                      35
<PAGE>
 
Investment Shares; assisting customers in changing dividend options, account
designations, and addresses; and providing such other services as the
Distributor may reasonably request in connection with investments in
Investment Shares. As of the date of this Prospectus, The Huntington
Investment Company and Huntington have entered into agreements with the
Distributor concerning the provision of administrative services to customers
of the Huntington Group who purchase Investment Shares of the Funds.
 
  In connection with the provision of the distribution and administrative
services described above, the Distributor will pay brokers, dealers and
administrators (including The Huntington Investment Company) a fee based on
the amount of Investment Shares owned by their customers. For all of the Funds
except the Mortgage Securities Fund and the U.S. Treasury Money Market Fund,
the schedules of such fees and the basis upon which such fees will be paid
will be determined, from time to time, by the Trustees. Under such
Distribution Plan, fees paid by the Distributor for services rendered with
respect to a Fund's Investment Shares will be reimbursed by the Fund in an
amount which may not exceed an annual rate of 0.25 of 1% of the average daily
net assets attributable to the Fund's Investment Shares held in customer
accounts for which brokers, dealers, and administrators provide such services.
Fees under the Distribution Plan with respect to each Fund's Investment Shares
are accrued daily, payable quarterly, and calculated on an annual basis.
 
  The Mortgage Securities Fund and the U.S. Treasury Money Market Fund have
adopted a separate Distribution Plan pursuant to Rule 12b-1 under the 1940 Act
(the "Compensation Plan" and, with the Distribution Plan, the "Distribution
Plans"). The Mortgage Securities Fund will pay to the Distributor an amount,
computed at an annual rate of 0.50 of 1% of the average daily net asset value
of the Mortgage Securities Fund's Investment Shares, to finance any activity
which is principally intended to result in the sale of Investment Shares
subject to the Compensation Plan. The U.S. Treasury Money Market Fund will pay
to the Distributor an amount computed at an annual rate of 0.25% of the
average daily net asset value of the U.S. Treasury Money Market Fund's
Investment Shares to finance any activity which is principally intended to
result in the sale of Investment Shares subject to the Compensation Plan.
These activities are extremely similar, and in some cases identical, to the
types of administrative services that are furnished to the Trust's other Funds
pursuant to the Distribution Plan (and described above). The Distributor may,
from time to time and for such periods as it deems appropriate, voluntarily
reduce its compensation under the Compensation Plan to the extent expenses
attributable to the Mortgage Securities Fund's and the U.S. Treasury Money
Market Fund's Investment Shares exceed such lower expense limitation as the
Distributor may, by notice to the Trust, voluntarily declare to be effective.
 
  The Mortgage Securities and the U.S. Treasury Money Market Funds' plan is a
compensation type plan. As such, the Funds make no payments to the Distributor
except as described above. Therefore, the Funds do not pay for unreimbursed
expenses of the Distributor, including amounts expended by the Distributor in
excess of amounts received by it from the Funds, interest, carrying or other
financing charges in connection with excess amounts expended, or the
Distributor's overhead expenses. However, the Distributor may be able to
recover such amounts or may earn a profit from future payments made by the
Funds under the Compensation Plan.
 
  The Glass-Steagall Act prohibits a depository institution (such as a
commercial bank or a savings and loan association) from being an underwriter
or distributor of most securities. In the event the Glass-Steagall Act is
deemed to prohibit depository institutions from acting in the administrative
 
                                      36
<PAGE>
 
capacities described above or should Congress relax current restrictions on
depository institutions, the Trustees will consider appropriate changes in the
administrative services performed in connection with the Distribution Plans.
 
  State securities laws governing the ability of depository institutions to
act as underwriters or distributors of securities may differ from
interpretations given to the Glass-Steagall Act and, therefore, banks and
financial institutions may be required to register as brokers or dealers
pursuant to state law.
 
  Shareholder Servicing Arrangements. In addition to the fees paid by the
Distributor to financial institutions under the Distribution Plans as
described above, the Distributor may also pay financial institutions a fee
based upon the average net asset value of Investment Shares held by their
customers for providing administrative services. This fee, if paid, will be
reimbursed by the Huntington and not the Funds.
 
ADMINISTRATION OF THE FUNDS
 
  SEI Financial Management Corporation, an affiliate of the Distributor,
provides the Funds with certain administrative personnel and services
necessary to operate the Funds. For these services, each of the Funds pays a
fee, computed and payable daily, to SEI Financial Management Corporation at an
annual rate of 0.11% of their average daily net assets. SEI Financial
Management Corporation has entered into an agreement with Huntington pursuant
to which Huntington provides certain administrative services to the Funds. The
fees paid to Huntington under this agreement are paid by SEI Financial
Services Corporation and not by the Funds.
 
CUSTODIAN, RECORDKEEPER, TRANSFER AGENT, AND DIVIDEND DISBURSING AGENT
 
  Huntington acts as custodian and recordkeeper of the Trust's investments and
other assets, except for the Mortgage Securities Fund, where Huntington acts
only as custodian. Huntington receives custody and recordkeeping fees of 5.6
basis points (0.056%) for each Fund except the Mortgage Securities Fund, for
which Huntington receives 2.6 basis points (0.026%) for custody services only.
American Data Services, Inc., acts as recordkeeper for the Mortgage Securities
Fund, for which it receives an annual fee of $75,000. SEI Financial Management
Corporation, serves as the Trust's transfer agent and dividend disbursing
agent. SEI Financial Management Corporation has entered into an agreement with
State Street Bank and Trust Company and Huntington pursuant to which State
Street Bank and Huntington provide certain transfer agency services to the
Funds. The fees paid under this agreement are paid by SEI Financial Management
Corporation and not by the Funds.
 
INDEPENDENT ACCOUNTANTS
 
  The independent accountants for the Trust are Price Waterhouse LLP,
Columbus, Ohio.

                            DISTRIBUTIONS AND TAXES
 
MONEY MARKET FUNDS
 
  All of the net income of both classes of shares of each Money Market Fund is
declared each Business Day as a dividend to shareholders of record at the time
of the declaration. A Money Market Fund's net income from the time of the
immediately preceding dividend declaration consists of interest accrued or
discount earned during such period (including both original issue and market
discount) on the Money Market Fund's securities, less amortization of premium
and the estimated expenses of each class of shares of the Money Market Fund.
Shares purchased prior to 10:30 a.m. (Eastern Time) begin earning dividends
that day. Shares purchased after such time begin earning dividends on the
following day. Dividends are declared daily and payable monthly.
 
  Although none of the Money Market Funds expects to realize long-term capital
gains, any net long-term capital gains that may be realized will be paid
annually. Each Money Market Fund expects to distribute any net realized short-
term gains once each year, although it may distribute them more frequently if
necessary in order to maintain the net asset value of each Money Market Fund
at $1.00 per share.
 
OTHER FUNDS
 
  Dividends, if any, from the investment income of each Fund other than the
Money Market Funds are declared and paid monthly to both classes of shares.
Distributions resulting from any net realized capital gains of any Fund will
be paid at least annually.
 
DISTRIBUTION OPTIONS
 
  Shareholders of the Money Market Funds may choose to receive all
distributions in cash or to reinvest all distributions in additional
Investment Shares of a Fund. Shareholders of other Funds may choose to receive
all distributions in cash, to reinvest all distributions in additional
Investment Shares, or to reinvest all capital gains distributions in
additional Investment Shares and to receive all other distributions in cash.
Shareholders may choose a distribution option by selecting the appropriate
option on the Account Registration Form or by notifying the appropriate member
of the Huntington Group of their selection. If a shareholder fails to choose a
distribution option, all distributions will be reinvested in additional
Investment Shares of the Fund making the distribution.
 
FEDERAL INCOME TAXES
 
  Each Fund intends to qualify as a "regulated investment company" for federal
income tax purposes and to meet all other requirements that are necessary for
it to be relieved of federal taxes on income (and gains, if any) paid to
shareholders in the form of dividends. In order to accomplish this goal, each
Fund must, among other things, distribute substantially all of its ordinary
income (and net short-term capital gains, if any) on a current basis and
maintain a portfolio of investments which satisfies certain diversification
criteria.
 
  All distributions by a Fund to a shareholder (with the exception of
distributions of tax-exempt income by the Ohio Funds and other than long-term
capital gain distributions, if any) will be taxable as ordinary income to the
extent of a Fund's current and accumulated "earnings and profits." However,
shareholders not subject to tax on their income generally will not be required
to pay tax on amounts distributed to them. The dividends received deduction
for corporations will apply to ordinary income distributions to the extent the
distribution represents amounts that would qualify for the dividends received
deduction to the Fund if the Fund were a regular corporation, and to the
extent designated by the Fund as so qualifying. The Money Market Funds and the
Income Funds do not expect to pay
 
                                      38
<PAGE>
 
any distributions that would be eligible for the dividends received deduction.
If a Fund were to have net long-term capital gains in excess of short-term
losses in a particular year, distributions by a Fund of those gains will be
taxable to a shareholder as long-term capital gains, regardless of how long a
shareholder has held the shares. If a shareholder disposes of shares at a loss
before holding such shares for longer than six months, such loss will be
treated as a long-term capital loss to the extent the shareholder has received
a long-term capital gains dividend on the shares.
 
  In general, dividends paid by the Ohio Funds that are designated by the
Funds as "exempt-interest dividends" will be exempt from regular income tax.
However, under the Internal Revenue Code of 1986, as amended (the "Code"),
dividends paid by the Ohio Funds attributable to interest on certain private
activity bonds issued after August 7, 1986, must be included as an item of tax
preference in computing alternative minimum taxable income for the purpose of
determining liability (if any) for the 26%-28% federal alternative minimum tax
for individuals and the 20% federal alternative minimum tax for corporations.
In addition, exempt-interest dividends paid by the Ohio Funds will be included
in a corporation's "adjusted current earnings" for purposes of the alternative
minimum tax. Thus, a corporation's alternative minimum tax base would
generally be increased by 75% of interest received which is excluded from
gross income for regular federal income tax purposes (other than dividends
paid by the Ohio Funds attributable to interest on certain private activity
bonds issued after August 7, 1986, which interest would already be included in
alternative minimum taxable income as a specific item of tax preference).
 
  Early in each year each Fund will notify each of its shareholders of the
amount and the federal income tax status of the distributions paid or deemed
paid to the shareholder by the Fund during the preceding year.
 
  If a shareholder receives an exempt-interest dividend with respect to a
share and holds the share for six months or less, any loss on the sale or
exchange of the share will be disallowed to the extent of the amount of such
exempt-interest dividend. The Treasury Department is authorized to issue
regulations reducing the period to not less than 31 days for regulated
investment companies that regularly distribute at least 90% of their net tax-
exempt interest. No such regulations have been issued as of the date of this
Prospectus.
 
  Distributions will be taxable as described above whether received in cash or
in shares through the reinvestment of distributions. A dividend paid to a
shareholder by a Fund in January of a year generally is deemed to have been
received by the shareholder on December 31 of the preceding year, if the
dividend was declared and payable to shareholders of record on a date in
October, November or December of that preceding year.
 
  Additional information regarding federal income taxes is contained in the
Statement of Additional Information. The foregoing is a general and
abbreviated summary of certain applicable provisions of the Code and Treasury
regulations currently in effect. The Code and regulations are subject to
change by legislative or administrative action. A Fund's distributions may
also be subject to state and local taxes. Shareholders should consult their
own tax adviser to determine the precise effect of an investment in a Fund on
their particular tax situation.
 
OHIO PERSONAL INCOME TAXES
 
  Dividends received from the Ohio Funds that are derived from interest on
Ohio tax-exempt securities are exempt from the Ohio personal income tax.
Specific state statutes authorizing the issuance of certain Ohio tax-exempt
securities provide that the interest on and gain from the sale or
 
                                      39
<PAGE>
 
other disposition of such obligations are exempt from all taxation in the
State. Dividends on shares of an Ohio Fund which are attributable to interest
on or gain from the sale of obligations issued pursuant to such statutes
should be exempt from the Ohio personal income tax. Ohio municipalities may
not impose income taxes on dividends or any intangible property, including
shares of the Ohio Funds, except that municipalities that taxed the types of
intangible income which were not exempt from municipal income taxation on or
before April 1, 1986, may tax such intangible income if such a tax was
approved by the electors of the municipality in an election held on November
8, 1988. Ohio residents should consult their own tax adviser regarding
potential municipal income tax liability in connection with their investment
in an Ohio Fund. The description in this paragraph, which is only a summary of
the Ohio tax treatment of dividends paid by the Ohio Funds, is based upon
current statutes and regulations and upon current policies of the Ohio
Department of Taxation, all of which are subject to change.
 
                           ORGANIZATION OF THE TRUST
 
  The Trust was organized as a Massachusetts business trust on February 10,
1987. A copy of the Trust's Declaration of Trust, which is governed by
Massachusetts law, is on file with the Secretary of State of The Commonwealth
of Massachusetts.
 
  The Trust is an open-end management investment company, whose Declaration of
Trust permits the Trust to offer separate series of shares of beneficial
interest representing interests in separate portfolios of securities. The
shares in any one portfolio may be offered in two or more separate classes. As
of the date of this Prospectus, the Trustees have established two classes of
shares, known as Investment Shares and Trust Shares, in the Money Market Fund,
the Ohio Municipal Money Market Fund, the U.S. Treasury Money Market Fund, the
Growth Fund, the Mortgage Securities Fund, the Ohio Tax-Free Fund, and the
Fixed Income Securities Fund.
 
  Investment Shares and Trust Shares of a Fund are fully transferable. Each
class is entitled to dividends from the respective class assets of the Fund as
declared by the Trustees, and, if the Trust (or the Fund) were liquidated, the
shareholders of each class would receive the net assets of the Fund
attributable to each respective class.
 
VOTING RIGHTS
 
  Shareholders are entitled to one vote for each share held on the record date
for any action requiring a vote by the shareholders, and a proportionate
fractional vote for each fractional share held. Shareholders of the Trust will
vote in the aggregate and not by Fund or class except (i) as otherwise
expressly required by law or when the Trustees determine that the matter to be
voted upon affects only the interests of the shareholders of a particular Fund
or class, and (ii) only holders of Investment Shares will be entitled to vote
on matters submitted to shareholder vote with respect to the Rule 12b-1 Plan
applicable to such class.
 
  As of April 10, 1996, National Financial Services Corp., New York, New York,
was the owner of record of approximately 40,016,001 shares (46.4%) and
Huntington, acting in various capacities for numerous accounts, was the owner
of 18,824,031 (21.2%) of the Investment Shares of the Money Market Fund; as of
April 10, 1996, Huntington, acting in various capacities for numerous
accounts, was the owner of record of approximately 60,650,636 shares (78.0%)
of the Investment Shares of the Ohio Municipal Money Market Fund; as of April
10, 1996, Huntington, acting in various capacities for numerous accounts, was
the owner of 12,548,643 shares (28.1%), Lenora J. Petraca of Akron, Ohio was
the owner of 2,771,233 shares (6.2%) and Allied Fidelity Insurance Co.,
Indianapolis, Indiana was
 
                                      40
<PAGE>
 
the owner of 3,610,280 shares (8.1%) of the Investment Shares of the U.S.
Treasury Market Fund. Such persons or entities may, for certain purposes, be
deemed to control the respective Funds and be able to affect the outcome of
certain matters presented for a vote of shareholders.
 
  As of April 10, 1996, Huntington, acting in various capacities for numerous
accounts, was the owner of record of approximately 296,005,400 shares (99.8%)
of the Trust Shares of the Money Market Fund; 51,512,824 shares (99.9%) of the
Trust Shares of the Ohio Municipal Money Market Fund; 302,462,286 shares
(99.9%) of the Trust Shares of the U.S. Treasury Money Market Fund; 5,077,082
shares (99.0%) of the Trust Shares of the Growth Fund; 5,494,723 shares
(98.8%) of the Trust Shares of the Income Equity Fund; 6,055,815 shares
(98.6%) of the Trust Shares of the Mortgage Securities Fund; 2,610,200 shares
(93.8%) of the Trust Shares of the Ohio Tax-Free Fund; 6,442,907 shares
(99.4%) of the Trust Shares of the Fixed Income Securities Fund; and 6,154,618
shares (99.2%) of the Trust Shares of the Short/Intermediate Fixed Income
Securities Fund, and therefore, may, for certain purposes, be deemed to
control the respective Funds and be able to affect the outcome of certain
matters presented for a vote of shareholders.
 
  As a Massachusetts business trust, the Trust is not required to hold annual
meetings of shareholders, but may hold special meetings from time to time.
 
  Trustees may be removed by the Trustees or by shareholders at a meeting
called for that purpose. For information about how shareholders may call such
a meeting and communicate with other shareholders for that purpose, see the
Statement of Additional Information.
 
  To the extent that matters arise requiring a shareholder vote in which
Huntington may have a conflict of interest, Huntington will engage in a voting
practice known as reflexive voting, whereby the votes of those shares over
which it exercises discretion will be voted in proportion to the votes cast by
the other record owners.
 
  As used in this Prospectus and in the Statement of Additional Information, a
"vote of a majority of the outstanding shares" of the Trust or a particular
Fund or a particular class of shares of the Trust or a Fund means the
affirmative vote of the lesser of (a) more than 50% of the outstanding shares
of the Trust or such Fund or such class, or (b) 67% or more of the shares of
the Trust or such Fund or such class present at a meeting at which the holders
of more than 50% of the outstanding shares of the Trust or such Fund or such
class are represented in person or by proxy.
 
                       PERFORMANCE DATA AND COMPARISONS
 
  Yield and total return data for both classes of shares may, from time to
time, be included in advertisements about the Funds.
 
  Each of the Money Market Funds may show its yield and effective yield for
both classes of shares. A Money Market Fund's yield represents an
annualization of the change in value of a shareholder account excluding any
capital changes in the Fund for a specific seven-day period. Effective yield
compounds the Fund's yield for a year and is, for that reason, greater than
the Money Market Fund's yield.
 
  Yield for both classes of shares of each of the other Funds is calculated by
dividing the Fund's annualized net investment income per share during a recent
30-day period by the maximum public offering price per share on the last day
of that period. With respect to the Ohio Funds, the tax-equivalent yield of
each class of shares shows the effect on performance of the tax-exempt status
of distributions received from an Ohio Fund. Tax-equivalent yield reflects the
approximate yield that a
 
                                      41
<PAGE>
 
taxable investment must earn for shareholders at stated income levels to
produce an after-tax yield equivalent to an Ohio Fund's tax-exempt yield.
Total return for the one-year period and for the life of a Fund through the
most recent calendar quarter represents the average annual compounded rate of
return on a $1,000 investment in each class of the Fund. Total return may also
be presented for other periods.
 
  Yield, effective yield, tax-equivalent yield, and total return will be
calculated separately for Investment Shares and Trust Shares. Because
Investment Shares are subject to 12b-1 fees, the yield, effective yield, tax-
equivalent yield, and total return for Investment Shares will be lower than
that of Trust Shares for the same period. In addition, the sales load
applicable to Investment Shares of the Growth Fund, Mortgage Securities Fund,
Ohio Tax-Free Fund and Fixed Income Securities Fund also contributes to a
lower total return for such Funds' Investment Shares. The total return figures
quoted in advertisements will normally reflect the effect of the maximum sales
load. However, from time to time, these advertisements may include total
returns which do not reflect the effect of an applicable sales load.
 
  All data is based on a Fund's past investment results and is not intended to
indicate future performance. Investment performance for both classes is based
on many factors, including market conditions, the composition of a Fund's
portfolio, and the operating expenses of a Fund or a particular class.
Investment performance also often reflects the risks associated with the
Fund's investment objective and policies. These factors should be considered
when comparing a Fund's investment results to those of other mutual funds and
other investment vehicles.
 
  From time to time, advertisements for a Fund may refer to ratings, rankings,
and other information in certain financial publications and/or compare a
Fund's performance to certain indices.
 
                             SHAREHOLDER INQUIRIES
 
  Shareholder inquiries regarding the Funds should be directed to The
Huntington Investment Company, Huntington Center, 41 South High Street,
Columbus, Ohio 43287.
 
                            OTHER CLASSES OF SHARES
 
  Certain of the Funds also offer another class of shares called Trust Shares.
Trust Shares are sold through procedures established by the Distributor in
connection with the requirements of fiduciary, advisory, agency, and other
similar accounts maintained by or on behalf of customers of The Huntington
Trust Company, N.A. or its affiliates or correspondent banks. Trust Shares are
sold at net asset value and are subject to a minimum initial investment of
$1,000.
 
  Investment Shares and Trust Shares of any Fund are subject to certain of the
same expenses; however, Investment Shares are distributed under a Rule 12b-1
Plan pursuant to which the Distributor is paid a fee based upon a percentage
of the average daily net assets attributable to a Fund's Investment Shares.
Expense differences between a Fund's Investment Shares and Trust Shares may
affect the performance of each class.
 
  Investors may obtain information about Trust Shares by contacting the
Distributor.
 
 
                  PENDING LEGAL PROCEEDINGS RELATING TO PIPER
 
  A number of complaints and arbitrations have been filed against Piper
relating to several other investment companies for which Piper acts as
investment adviser or subadviser. These lawsuits and arbitrations do not
involve the Mortgage Securities Fund and Piper does not believe that the
lawsuits will have a material adverse effect upon its ability to perform under
their agreement with Huntington. Settlements have been reached with respect to
a number of such actions. Piper intends to defend, or in some cases negotiate
to settle, the remaining actions. See "Pending Litigation Relating to Piper"
in the Statement of Additional Information.

                                  APPENDIX I
 
  Rule 2a-7, as amended, defines the terms NRSRO, Eligible Securities, Unrated
Securities, First Tier Securities and Second Tier Securities in establishing
risk limiting conditions for money market mutual funds.
 
  A summary of those definitions follows.
 
  NRSRO is any nationally recognized statistical rating organization as that
term is used in the Securities Exchange Act of 1934, that is not an affiliated
person of the issuer, guarantor or provider of credit support for the
instrument. (While the Appendix to the Statement of Additional Information
identifies each NRSRO, examples include Standard & Poor's Ratings Group
("Standard & Poor's"), Moody's Investors Service, Inc. ("Moody's") and Fitch
Investors Service, Inc.)
 
  ELIGIBLE SECURITIES are defined as those with a remaining maturity of 397 or
less days and which (i) have a short-term rating in one of the two highest
rating categories by an NRSRO (e.g. A-1/P-1 or A-2/P-2 by Standard & Poor's
and Moody's, respectively), (ii) securities that are comparable in priority
and security to other short-term debt of the issuer having a short-term rating
in one of the two highest rating categories or (iii) Unrated Securities that
are of comparable quality. A long-term security without a short-term rating
but with a long-term rating below the two highest rating categories (i.e., a
rating of A or below) is not an Eligible Security.
 
  UNRATED SECURITIES include (i) securities that do not have a current short-
term rating and that are not comparable in priority or security to another
class of the issuer's securities having a short-term rating and (ii)
securities that do have a rating, but are subject to an external credit
support agreement that was not in effect when the rating was assigned.
 
  FIRST TIER SECURITY means any Eligible Security which has, or is comparable
to short-term debt of the issuer having, the highest short-term rating by any
two NRSROs that have issued a rating with respect to a security or class of
debt obligations of an issuer. If only one NRSRO has issued a rating with
respect to such security, it must be the highest short-term rating given by
such NRSRO.
 
  SECOND TIER SECURITY means any Eligible Security that is not a First Tier
Security.
