ly, for the International Equity, International Small Cap Equity and Inter-
national Emerging Markets Portfolios, and administration fees would be .23%

trators are under no obligation to waive or continue waiving their fees,
but have informed the Fund that they expect to waive fees as necessary to
maintain the Portfolios' total operating expenses during the remainder of
the current fiscal year at the levels set forth in the table. Without waiv-
ers, "Other operating expenses" would be .69%, .67%, .71%, .85%, .92% and

International Equity, International Small Cap Equity, International Emerg-

The section "Who Manages The Fund?" is amended to reflect that effective March
31, 1998, BlackRock Financial Management, Inc. ("BlackRock") acts as sub-ad-
viser to each of the Portfolios other than the Index Equity Portfolio and the
International Portfolios as a result of the merger of Provident Capital Manage-
ment, Inc. and PNC Equity Advisors Company into BlackRock. BlackRock Interna-
tional, Ltd. (formerly CastleInternational Asset Management Limited) acts as
sub-adviser to each of the International Portfolios.
The section "How Are Shares Purchased And Redeemed?" has been amended as fol-
lows:
The following replaces the first sentence under "Purchase of Shares":
Service Shares are offered without a sales load to Institutions acting on
behalf of their customers, certain persons who were shareholders of The
Compass Capital Group at the time of its combination with The PNC(R) Fund
during the first quarter of 1996, and investors that participate in the
Capital Directions SM asset allocation program.
The following has been added after the last paragraph under "Purchase of
Shares":
In the event that a shareholder acquiring Service Shares on or after May 1,
1998 (other than a former shareholder of The Compass Capital Group as de-
scribed above) ceases to meet the eligibility standards for purchasing
Service Shares, then the shareholder's Service Shares will, upon the direc-
tion of the Fund's distributor, automatically be converted to Investor A
Shares of the Portfolio having the same aggregate net asset value as the
shares converted. Investor A Shares are currently authorized to bear addi-
tional service and distribution fees at the aggregate annual rate of .20%
of average daily net assets. In the event that a shareholder acquiring
Service Shares on or after May 1, 1998 subsequently satisfies the eligibil-
ity standards for purchasing Institutional Shares (other than due to fluc-
tuations in market value), then the shareholder's Service Shares will, upon
the direction of the Fund's distributor, automatically be converted to In-
stitutional Shares of the Portfolio having the same aggregate net asset
value as the shares converted.
This Supplement is dated May 1, 1998.

The section "How Are Shares Purchased And Redeemed?" has been amended as fol-
lows:
The following replaces the first paragraph under "Purchase of Shares":
Institutional Shares are offered to institutional investors, including (a)
registered investment advisers with a minimum investment of $500,000 and
(b) the trust departments of PNC Bank and its affiliates (collectively,
"PNC") on behalf of clients for whom PNC (i) acts in a fiduciary capacity
(excluding participant-directed employee benefit plans) or otherwise has
investment discretion or (ii) acts as custodian with respect to at least
$2,000,000 in assets, and individuals with a minimum investment of
$2,000,000.
The following has been added after the last paragraph under "Purchase of
Shares":
In the event that a shareholder acquiring Institutional Shares on or after
May 1, 1998 ceases to meet the eligibility standards for purchasing Insti-
tutional Shares (other than due to fluctuations in market value), then the
shareholder's Institutional Shares will, upon the direction of the Fund's
distributor, automatically be converted to shares of another class of the
Portfolio having the same aggregate net asset value as the shares convert-
ed. If, at the time of conversion, an institution offering Service Shares
of the Portfolio is acting on the shareholder's behalf, then the sharehold-
er's Institutional Shares will be converted to Service Shares of the Port-
folio. If not, then the shareholder's Institutional Shares will be con-
verted to Investor A Shares of the Portfolio. Service Shares are currently
authorized to bear additional service and processing fees at the aggregate
annual rate of .30% of average daily net assets, while Investor A Shares
are currently authorized to bear additional service, processing and distri-
bution fees at the aggregate annual rate of .50% of average daily net as-
sets.

(1) Reduced front-end sales charges may be available. A deferred sales charge
of up to 1.00% is assessed on certain redemptions of Investor A Shares that
are purchased with no initial sales charge as part of an investment of
$1,000,000 or more. See "What Is the Schedule of Sales Charges and Exemp-
tions?"
(2) This amount applies to redemptions during the first year. The deferred
sales charge for Investor B Shares decreases for redemptions made in subse-
quent years. No deferred sales charge is charged after the sixth year on
Investor B Shares or after the first year on Investor C Shares. See "What
Is the Schedule of Sales Charges and Exemptions?"
(3) "Other expenses" includes the administration fees payable by the Portfo-
lios. Without waivers, advisory fees would be .80% and administration fees
would be .23% for the Mid-Cap Value Equity Portfolio. BlackRock, Inc. and
the Portfolios' administrators are under no obligation to waive or continue
waiving their fees, but have informed the Fund that they expect to waive
fees as necessary to maintain the Portfolios' total operating expenses dur-
ing the remainder of the current fiscal year at the levels set forth in the
table. Without waivers, "Other operating expenses" would be .86% for each
class of the Mid-Cap Value Equity Portfolio and "Total Portfolio operating
expenses" would be 1.66% for Investor A Shares and 2.41% for Investor B
Shares and Investor C Shares. The Portfolios do not expect to incur 12b-1
fees in excess of .005% with respect to Investor A Shares (otherwise pay-
able at the maximum rate of .10%) during the current fiscal year.
(4) Investors with a long-term perspective may prefer Investor A Shares, as de-
scribed under "What Are The Key Considerations In Selecting A Pricing Op-
tion?" Long-term investors in Investor Shares may pay more than the eco-
nomic equivalent of the maximum front-end sales charges permitted by the
rules of the National Association of Securities Dealers, Inc. ("NASD").

(1) Reduced front-end sales charges may be available. A deferred sales charge
of up to 1.00% is assessed on certain redemptions of Investor A Shares that
are purchased with no initial sales charge as part of an investment of
$1,000,000 or more. See "What Is the Schedule of Sales Charges and Exemp-
tions?"
(2) This amount applies to redemptions during the first year. The deferred
sales charge for Investor B Shares decreases for redemptions made in subse-
quent years. No deferred sales charge is charged after the sixth year on
Investor B Shares or after the first year on Investor C Shares. See "What
Is the Schedule of Sales Charges and Exemptions?"
(3) "Other expenses" includes the administration fees payable by the Portfo-
lios. Without waivers, advisory fees would be .75%, 1.00% and 1.25% for the
International Equity, International Small Cap Equity and International
Emerging Markets Portfolios, respectively, and administration fees would be
.23% for each class of each Portfolio. BlackRock, Inc. and the Portfolios'
administrators are under no obligation to waive or continue waiving their
fees, but have informed the Fund that they expect to waive fees as neces-
sary to maintain the Portfolios' total operating expenses during the re-
mainder of the current fiscal year at the levels set forth in the table.
Without waivers, "Other operating expenses" would be: (i) .88%, 1.02% and
1.09%, respectively, for each class of the Portfolios and "Total Portfolio
operating expenses" would be: (ii) 1.63%, 2.02% and 2.34%, respectively,
for Investor A Shares; and (iii) 2.38%, 2.77% and 3.09%, respectively, for
Investor B Shares and Investor C Shares. The Portfolios do not expect to
incur 12b-1 fees in excess of .005% with respect to Investor A Shares (oth-
erwise payable at the maximum rate of .10%) during the current fiscal year.
(4) Investors with a long-term perspective may prefer Investor A Shares, as de-
scribed under "What Are The Key Considerations In Selecting A Pricing Op-
tion?" Long-term investors in Investor Shares may pay more than the eco-
nomic equivalent of the maximum front-end sales charges permitted by the
rules of the NASD.

Portfolio having the same aggregate net asset value as the shares convert-

of the Portfolio is acting on the shareholder's behalf, then the sharehold-
er's Institutional Shares will be converted to Service Shares of the Port-
folio. If not, then the shareholder's Institutional Shares will be con-
verted to Investor A Shares of the Portfolio. Service Shares are currently
authorized to bear additional service and processing fees at the aggregate
annual rate of .30% of average daily net assets, while Investor A Shares
are currently authorized to bear additional service, processing and distri-
