The following paragraphs replace the second paragraph under AGGRESSIVE
GROWTH FUND on page 8:
2. As of February 5, 1998, the Aggressive Growth Fund no longer follows
a "bottom-up" securities selection strategy, but instead employs a
"quantitative" investment approach. Under this approach, stocks are ranked
according to their return characteristics and other quantitative factors. The
portfolio is being constructed to exhibit aggregate investment characteristics
similar to those of the Standard & Poor's Small Cap 600 Index ("S&P 600"). The
Aggressive Growth Fund will not, however, seek to match or track the performance
of the S&P 600, nor limit investments to stocks in this Index. This
"quantitative" investment approach is being implemented gradually over the next
few months.
The securities of smaller, less well-known companies may be more
volatile than those of larger companies. An investment in the Aggressive Growth
Fund may increase or decrease in value.
3. The following paragraph replaces the second paragraph under GENERAL
INFORMATION - DESCRIPTION OF THE FUNDS AND THEIR SHARES on page 29:
As of April 14, 1998, Bank of Oklahoma, N.A. (Bank of Oklahoma Tower,
One Williams Center, Tulsa, Oklahoma 74103) and its bank affiliates were the
Shareholder of record of 99% of the Equity Fund's Shares, 93% of the Aggressive
Growth Fund Shares, 98% of the Balanced Fund's Shares and 99% of the Growth
Equity Fund's Shares. As of March 31, 1998, Bank of Oklahoma, N.A. and its bank
affiliates possessed, on behalf of its underlying accounts, voting and
investment power with respect to 77% of the Equity Fund's Shares, 61% of the
Aggressive Growth Fund's shares, 58% of the Balanced Fund's Shares and 98% of
the Growth Equity Fund's Shares, and, as a consequence, Bank of Oklahoma, N.A.
and its bank affiliates may be deemed to be a controlling person of each Fund
under the 1940 Act.
INVESTORS SHOULD RETAIN THIS SUPPLEMENT WITH THE PROSPECTUS FOR
FUTURE REFERENCE.

reductions, the investment advisory fees would be 0.55% of the average daily net
assets for the Bond Fund, Intermediate Bond Fund, Intermediate Tax-Free Bond
Fund and Short-Term Income Fund.
(5) In order to reduce operating expenses, the Distributor has
voluntarily agreed to reduce the 12b-1 Fees. Absent voluntary fee
reductions, 12b-1 Fees would be 0.25% of the average daily net assets of the
Intermediate Tax-Free Bond Fund and the Short-Term Income Fund.
(6) Absent voluntary fee reductions, the Total Fund Operating Expenses
for the Bond Fund, Intermediate Bond Fund, Intermediate Tax-Free Bond Fund and
Short-Term Income Fund would be 1.14%, 1.13%, 1.19% and 1.20% of each Fund's
