Dear Shareholder:

     I invite you to attend a Special Meeting of Shareholders of The
Nicholas-Applegate International All-Cap Growth Fund (the "Fund") to be held on
Friday, November 18, 2005, at 10:00 a.m. The meeting will be held at the offices
of the Fund, 615 East Michigan Street, 3rd Floor, Milwaukee, Wisconsin.

     The accompanying Combined Proxy Statement/Prospectus contains an important
proposal for your consideration as a shareholder of the Fund. Your Board of
Trustees has proposed that the Fund, formerly the Duncan-Hurst International
Fund, be merged into a newly created portfolio of Nicholas-Applegate
Institutional Funds using the same name, the Nicholas-Applegate International
All-Cap Growth Fund (the "Acquiring Fund"). If approved by the shareholders,
substantially all of the assets and liabilities of the Fund will be exchanged
for shares of the Acquiring Fund as more fully described in the accompanying
Notice and Combined Proxy Statement/Prospectus.

     THE BOARD OF TRUSTEES OF THE FUND BELIEVES THE PROPOSED REORGANIZATION WILL
BE IN THE BEST INTERESTS OF SHAREHOLDERS OF THE FUND. ACCORDINGLY, THE BOARD OF
TRUSTEES STRONGLY URGES YOU TO VOTE FOR THE PROPOSED REORGANIZATION. THE
REORGANZATION WILL BE EFFECTED ONLY IF APPROVED BY A MAJORITY OF THE FUND'S
OUTSTANDING SHARES VOTED IN PERSON OR REPRESENTED BY PROXY.

     The enclosed materials provide more information about the proposed
reorganization.

     Your vote is important. We urge you to complete, SIGN AND RETURN THE
ENCLOSED PROXY VOTING CARD so that your shares will be represented. EVERYTHING
YOU NEED IS ENCLOSED. By promptly returning the proxy card, you help avoid the
necessity and expense of follow-up mailings and telephone solicitations to
assure a quorum. If you later decide to attend the meeting, you may revoke your
proxy and vote your shares in person. If you have any questions, please call us
at 1-800-558-9105.

                        Sincerely,


                        Robert M. Slotky
                        President
                        The Nicholas-Applegate International All-Cap Growth Fund

                        Dated October 18, 2005

<Page>

WHAT YOU SHOULD KNOW ABOUT THE PROPOSED REORGANIZATION

     Nicholas-Applegate Capital Management LLC ("Nicholas-Applegate") and the
Board of Trustees of the Professionally Managed Portfolios encourage you to read
the enclosed Prospectus/Proxy Statement carefully. The following is designed to
provide a brief overview of the proposal and answer some questions you may have
about this shareholder vote.

WHAT IS THE PURPOSE OF THE SHAREHOLDER VOTE?

     The vote is to determine whether the Nicholas-Applegate International
All-Cap Growth Fund, a series of the Professionally Managed Portfolios (the
"Acquired Fund") should be reorganized and merged into a newly created portfolio
of the Nicholas-Applegate Institutional Funds using the same name (the
"Acquiring Fund"). If the Acquired Fund's shareholders decide in favor of the
proposal, you will become a shareholder of the Acquiring Fund, and the Acquired
Fund will cease to exist.

WHAT IS THE RATIONALE FOR MERGING THE ACQUIRED FUND AND THE ACQUIRING FUND?

     On June 30, 2005, Nicholas-Applegate and Duncan-Hurst Capital Management
entered into a purchase agreement pursuant to which Nicholas-Applegate acquired
the rights to manage the international assets previously managed by Duncan-Hurst
Capital Management, which included the assets of the Acquired Fund. The
acquisition by Nicholas-Applegate of the rights to manage Duncan-Hurst Capital
management's international assets was mutually agreed upon by each company to
enhance Nicholas-Applegate's international equity capabilities while
Duncan-Hurst Capital Management will continue to focus on its core strength in
the management of U.S. growth equities. Nicholas-Applegate and Duncan-Hurst
Capital Management each share a similar heritage of growth stock investing and
trace their roots back to pacific Century Advisers, a subsidiary of Security
Pacific Bank. Both companies received financial benefits from this agreement. In
connection with the acquisition, the Board named Nicholas-Applegate as interim
adviser to the Acquired Fund effective July 1, 2005 through November 28, 2005.
Nicholas-Applegate also manages the Nicholas-Applegate Institutional Funds, an
investment company with 13 separate portfolios registered under the Investment
Company Act of 1940. Nicholas-Applegate seeks to bring the Acquired Fund into
Nicholas-Applegate Institutional Funds to be marketed under its brand name and
to its institutional clients through an affiliated distributor,
Nicholas-Applegate Securities, LLC.

WHAT ARE THE ADVANTAGES OF MERGING THESE FUNDS?

     There are several key potential advantages:

     -  It is anticipated that the Acquiring Fund will likely have a better
        opportunity to raise asset levels if it can be marketed under the
        Nicholas-Applegate name to its institutional clients.

     -  Higher asset levels may lead to lower expense ratios over time. It is
        anticipated that merging the Acquired Fund into the Acquiring Fund
        will lower annual operating expenses.

     -  These lower costs may lead to stronger performance, since total return
        to a Fund's shareholders is net of Fund expenses for the Acquired Fund
        shareholders.

     The potential benefits and possible disadvantages of merging the Funds are
explained in more detail in the enclosed proxy statement.

HOW ARE THESE FUNDS ALIKE?

     The two Funds are substantially similar in terms of investment objectives,
policies, and strategies. Each Fund seeks long-term capital appreciation by
investing primarily in equity securities of issuers located in at least three
countries but typically in as many as fifteen to twenty-five countries outside
the United States. The Acquiring Fund will be managed by the same portfolio
management team of Vincent Willyard, CFA, Joseph Devine, and Barry Kendall.

<Page>

WHAT HAPPENS IF SHAREHOLDERS DECIDE IN FAVOR OF A REORGANIZATION?

     Acquired Fund shareholders will receive full and fractional Class I shares
of the Acquiring Fund equal in value to their shares that they owned on the
effective date of the reorganization.

IF THE FUNDS MERGE, WILL THERE BE TAX CONSEQUENCES FOR YOU?

     Unlike a transaction in which you direct Nicholas-Applegate to sell shares
of one fund to buy shares of another, an exchange of shares pursuant to a
reorganization is not considered a taxable event. The Funds themselves also will
recognize no gains or losses as a result of a reorganization, except with
respect to the Acquired Fund's assets that are sold in connection with its
reorganization. Accordingly, you will not have to report any capital gains due
to a reorganization, although you may receive a distribution of ordinary income
and/or capital gains immediately before its reorganization to the extent that
the Acquired Fund has undistributed income and/or gains.

     You should consult your tax advisor regarding any possible effect a
reorganization might have on your tax situation, given your personal
circumstances -- particularly regarding state and local taxes.

WHO WILL PAY FOR THE REORGANIZATION?

     The expenses of the reorganization, including legal expenses, printing,
packaging, and postage, plus the costs of any supplementary solicitation, will
be borne by Nicholas-Applegate.

WHAT DOES THE BOARD RECOMMEND?

     The Board believes you should vote in favor of the reorganization. More
importantly, however, the Board recommends that you study the issues involved,
call us with any questions, and vote promptly to ensure that a quorum will be
represented at the Meeting.

WHERE CAN I GET MORE INFORMATION ABOUT THE ACQUIRING FUND?

     We hope this Q&A has helped you better understand why we are making this
proposal. If you have any questions, we encourage you to call us at
1-800-558-9105.

                                   ----------

      SPECIAL MEETING OF SHAREHOLDERS TO BE HELD FRIDAY, NOVEMBER 18, 2005

     This Combined Proxy Statement and Prospectus ("Statement") is furnished in
connection with the solicitation of proxies by the Board of Trustees of the
Professionally Managed Portfolios for the Special Meeting of Shareholders (the
"Special Meeting") of the Nicholas-Applegate International All-Cap Fund
(formerly the Duncan Hurst International Fund) (the "Fund") to be held on
Friday, November 18, 2005, at 10:00 a.m., Eastern time. The meeting will be held
at the offices of Fund, 615 East Michigan Street, 3rd Floor, Milwaukee,
Wisconsin 53202.

     As more fully described in this Statement, the purpose of the Special
Meeting is to vote on a proposed Agreement and Plan of Reorganization (the
"Reorganization"). In the Reorganization, the Nicholas-Applegate International
All-Cap Growth Fund, a newly created portfolio of the Nicholas-Applegate
Institutional Funds (the "Acquiring Fund") will acquire substantially all of the
assets of the Nicholas-Applegate International All-Cap Growth Fund, a portfolio
of the Professionally Managed Portfolios (the "Acquired Fund"), in exchange
solely for its shares and the assumption of all of the Acquired Fund's
liabilities, followed by the distribution of those shares to the Acquired Fund's
shareholders. As a result, each of the Acquired Fund's shareholders will receive
a number of full and fractional Class I shares of the Acquiring Fund having an
aggregate value that on effective date of the Reorganization is equal to the
aggregate value of the shareholder's Acquired Fund's shares. As soon as
practicable following the distribution of the Acquiring Fund's Class I shares,
the Acquired Fund will be terminated.

     This Statement sets forth concisely the information that shareholders of
the Acquired Fund should know before voting on the Reorganization. This
Statement should be retained for future reference. A copy of the Agreement and
Plan of Reorganization is attached to this Statement as Exhibit A and is
incorporated herein by reference.

     A Preliminary Prospectus for the Acquiring Fund (SEC File #811-07384),
which describes the investment objectives, program, policies and risks of the
Acquiring Fund, accompanies this Statement. A Prospectus for the Acquired Fund
(SEC File #811-05037), dated July 29, 2005, was previously provided to
shareholders. Additional information concerning the Acquiring Fund is set forth
in the preliminary Statement of Additional Information which accompanies this
Statement, and additional information concerning the Acquired Fund is set forth
in the Statement of Additional Information (SEC File #811-05037) dated July 29,
2005. Each of these documents is on file with the Securities and Exchange
Commission, and is available without charge upon oral or written request by
writing or calling The Professionally Managed Portfolios or Nicholas-Applegate
Institutional Funds at the address and telephone numbers listed under the
section "Additional Information About Each Fund". The Prospectus for the
Nicholas-Applegate Institutional Funds is also available on its website at
http:\\www.nacm.com. The Securities and Exchange Commission maintains a website
at http:\\www.sec.gov that contains the Prospectuses, Statements of Additional
Information, material incorporated by reference and other information regarding
The Professionally Managed Portfolios, the Nicholas-Applegate Institutional
Funds, and other registrants that file electronically with the Securities and
Exchange Commission. The information contained in each of these Prospectuses and
Statements of Additional Information is incorporated into this Statement by
reference.

                                    SYNOPSIS

     The following is a summary of certain background information relating to
the proposed Reorganization, the parties thereto and the transactions
contemplated thereby, and is qualified by reference to the more complete
information contained elsewhere in this Statement, the Prospectus, Statement of
Additional Information, Annual and Semi-Annual Reports of the Acquired Fund, the
Preliminary Prospectus and Statement of Additional Information of the Acquiring
Fund, and the Agreement and Plan of Reorganization.

     At a meeting held on June 13, 2005, the Board of Trustees of the Acquired
Fund (the "Board") approved Nicholas-Applegate Capital Management
("Nicholas-Applegate") as the interim adviser to the Acquired Fund, effective
from July 1, 2005 through November 28, 2005, to replace Duncan Hurst Capital
Management ("Duncan Hurst"), who had resigned as investment adviser of the
Acquired Fund following the transfer of its international assets to
Nicholas-Applegate. Nicholas-Applegate is also the investment adviser of the
Nicholas-Applegate Institutional Funds, a registered investment company whose
thirteen portfolios Nicholas-Applegate markets primarily to institutional
investors. The Acquiring Fund is a portfolio of the Nicholas-Applegate
Institutional Funds. At a meeting held on August 12, 2005 of the Board,
Nicholas-Applegate asked the Board to approve an Agreement and Plan of
Reorganization ("Reorganization"), subject to shareholder ratification, whereby
the Acquired Fund and the Acquiring Fund would merge. At that meeting, the Board
unanimously approved the Reorganization.

     The investment objectives, investment policies and restrictions of the
Acquired Fund and the Acquiring Fund (collectively, the "Funds") are
substantially similar. Both Funds seek long-term capital appreciation by
investing primarily in a diversified portfolio of equity and equity-related
securities of companies located in developed non-U.S. markets. Under normal
market conditions the Acquiring Fund will invest 80% of its total net assets in
equity and equity-related securities of issuers located in a number of different
countries, typically as many as fifteen to twenty-five countries outside the
United States. The Acquiring Fund will invest in companies of any size, from
larger, well-established companies to smaller emerging growth companies. The
investment objectives of the Acquiring Fund may not be changed without a vote of
the holders of a majority of the outstanding shares of the Acquiring Fund.

     Shares of the Acquired Fund are sold on a 100% no-load basis, meaning that
such shares may be purchased, redeemed, or exchanged at their net asset value
without payment of a sales charge. In addition, the Acquired Fund does not
charge Rule 12b-1 fees but does impose a redemption fee of 2.00% on shares held
less than four months. Acquiring Fund shares will be soled on a 100% no-load
basis and do not charge Rule 12b-1 fees. The Acquiring Fund will not impose a
redemption fee. The purchase price for shares of the Acquiring Fund will be the
net asset value next determined after the Acquiring Fund receives the
shareholder's request in proper form. Please note that Acquiring Fund shares may
be exchanged for shares in any of the other portfolios of the Nicholas-Applegate
Institutional Funds

PROPOSED REORGANIZATION

     Based on their evaluation of the relevant information presented to them,
and in light of their fiduciary duties under federal and state law, the Board,
including all of Trustees who are not "interested persons" of the Acquired Fund,
as that term is defined in the Investment Company Act of 1940, as amended ("1940
Act") ("Independent Trustees"), have determined that the proposed Reorganization
is in the best interests of the shareholders of the Acquired Fund. The Board
recommends the approval of the Reorganization Agreement and related transactions
by the shareholders of the Acquired Fund at the Special Meeting.

     Subject to shareholder approval, the Reorganization provides for: (a) the
transfer to the Acquiring Fund of substantially all of the property, assets,
liabilities and goodwill of the Acquired Fund (the "Acquired Fund Net Assets")
in exchange for Class I shares of the Acquiring Fund equal in value ("Acquiring
Fund Shares") to the Acquired Fund Net Assets; (b) the distribution of Acquiring
Fund Shares to the shareholders of the Acquired Fund in liquidation of the
Acquired Fund; and (c) the cancellation of all outstanding Acquired Fund Shares.

     As a result of the proposed Reorganization, each shareholder of the
Acquired Fund will become a shareholder of the Acquiring Fund and will hold,
upon consummation of the Reorganization, Acquiring Fund Shares having a net
asset value equal to the net asset value of the Acquired Fund Shares held by the
shareholder immediately before consummation of the Reorganization. Acquiring
Fund offers shares in Class I, Class II, Class III and Class IV; however, only
Class I is involved in this Reorganization.

     For further information, see the discussion below on whether to approve or
disapprove the Reorganization, which includes a description of the Agreement and
Plan of Reorganization Agreement.

REASONS FOR THE REORGANIZATION

     In light of certain potential benefits and other factors, the Board
including the Independent Trustees, determined that it is in the best interests
of the Acquired Fund and its shareholders to reorganize into the Acquiring Fund.
In making that determination, the Board of Trustees considered various issues,
as described more fully under "Reasons for the Reorganization."

     The Board believes that the Reorganization with respect to the Acquired
Fund in most cases will: (a) provide Acquired Fund shareholders with an
investment fund that has the same investment adviser and investment objective,
and substantially similar investment policies, restrictions, and investment
strategies as the Acquired Fund; (b) provide Acquired Fund shareholders with
overall expense ratios that are more favorable than those of the Acquired Fund;
(c) provide Acquired Fund shareholders with an opportunity to be invest in a
fund that has the potential to achieve better economies of scale by being
marketed under the Nicholas-Applegate name and to the institutional clients of
Nicholas-Applegate and (d) provide Acquired Fund shareholders with a fund that
affords greater investment opportunities by allowing no-load exchange privileges
with other funds of the Nicholas-Applegate Institutional Funds.

     The Board also considered the reasonably likely risks and disadvantages of
the Reorganization and determined that the Reorganization is likely to provide
benefits to the Acquired Fund and their shareholders that outweigh any possible
risks and disadvantages of the Reorganization. Finally, the Board concluded that
there are no reasonably significant risks or disadvantages to the Acquired Fund
or its shareholders from the Reorganization and that the interests of the
Acquired Fund's shareholders would not be diluted.

     Similarly, the Board of Trustees of Nicholas-Applegate Institutional Funds,
in approving the Reorganization, determined that it would be advantageous for
its current shareholders to acquire the Acquired Fund Net Assets in exchange for
the Acquiring Fund Shares and that the interests of the Acquiring Fund's
existing shareholders would not be diluted.

INVESTMENT ADVISER

     Nicholas-Applegate, 600 West Broadway, San Diego, California 92101 is the
investment adviser to the Acquiring Fund and the interim investment manager to
the Acquired Fund. After consummation of the Reorganization, Nicholas-Applegate
would continue to manage the Acquiring Fund, which would include assets from the
Acquired Fund. As of June 30, 2005 Nicholas-Applegate had approximately $14
billion under management.

FEDERAL INCOME TAX CONSEQUENCES

     Counsel for this transaction will issue an opinion as of the Closing Date
to the effect that the Reorganization will not give rise to the recognition of
income, gain, or loss for federal income tax purposes to the Acquired Fund, the
Acquiring Fund, or their respective shareholders. See the discussion below on
whether to approve or disapprove the Reorganization, which includes a
description of the Reorganization Agreement.

             COMPARISON OF THE ACQUIRED FUND AND THE ACQUIRING FUND

PRINCIPAL INVESTMENTS

     The Acquired Fund is a series of the Professionally Managed Portfolios, a
Massachusetts business trust. The Acquiring Fund is a newly created series of
Nicholas-Applegate Institutional Funds, which is a Delaware business trust. The
Acquiring Fund has no performance history.

     Nicholas-Applegate intends to manage the Acquiring Fund in a substantially
similar investment style to that of the Acquired Fund. The objective of both
Funds is to seek long-term capital growth by investing in a diversified
portfolio of equity securities of companies located in developed markets outside
the United States. This objective for the Acquiring Fund cannot be changed
without shareholder approval. The Acquiring Fund will invest at least 80% of its
total net assets in equity securities of companies in a number of different
countries, typically as many as fifteen to

                                        6
<Page>

twenty five outside the United States. Under normal circumstances, the Acquired
Fund may invest a minimum of 65% of its total net assets in equity securities of
companies in as few as three, but typically invests in as many as fifteen to
twenty five countries outside the United States. Both the Acquired Fund and the
Acquiring Funds will invest in companies of any size from larger,
well-established companies to smaller, emerging growth companies.

     Nicholas-Applegate will continue to conduct individual company analysis on
a group of companies that meet its standards of positive change, sustainability
and timeliness. It will continue to identify companies experiencing accelerating
earnings, rising relative price strength and positive company fundamentals.
Nicholas-Applegate will continue to focus on a "bottom-up" analysis of
individual companies worldwide as well as a "top down" analysis to identify the
most attractive sectors and countries for investment.

     The Acquiring Fund may invest in companies in lesser-developed countries,
in various depositary receipts traded on domestic and foreign exchanges, as well
as foreign securities traded in the U.S. markets. The Acquiring Fund may also
lend portfolio securities on a short-term or long-term basis, up to 30% of its
total assets.

     Vincent Willyard, CFA, will continue to be the lead portfolio manager for
the Acquiring Fund. Mr. Willyard has served as the portfolio manager of the
Acquired Fund since its inception and was employed by Duncan-Hurst Capital
Management as an investment professional since 1994.

PRINCIPAL RISK CONSIDERATIONS

     The permitted investments of the Acquired Fund and the Acquiring Fund are
substantially similar. The following is an overview of the principal risks
involved in investing in the Acquiring Fund. A detailed description of the risks
involved in investing in the Acquiring Fund is contained in the Acquiring Fund's
Preliminary Prospectus and Statement of Additional Information.

     -  STOCK MARKET VOLATILITY -- The prices of equity securities change in
        response to many factors, including the historical and prospective
        earnings of the issuer, the value of its assets, general economic
        conditions, interest rates, investor perceptions, domestic and worldwide
        political events and market liquidity. Stock prices are unpredictable,
        may fall suddenly and continue to fall for extended periods.

     -  NON-U.S. SECURITIES RISKS -- The prices of non-U.S. securities may be
        further affected by other factors, including

               CURRENCY EXCHANGE RATES -- The dollar value of the Acquiring
               Fund's non-U.S. investments will be affected by changes in the
               exchange rates between the U.S. dollar and the currencies in
               which those investments are traded.

               POLITICAL AND ECONOMIC CONDITIONS -- The value of the Acquiring
               Fund's non-U.S. investments may be adversely affected by
               political and social instability in their home countries and by
               changes in economic and taxation policies in those countries.

               REGULATIONS -- Non U.S. companies generally are subject to less
               stringent regulations, including financial and accounting
               controls, than are U.S. companies. As a result, there generally
               is less publicly available information about non-U.S. companies
               than about U.S. companies.

               MARKETS -- The securities markets of other countries are smaller
               than U.S. securities markets. As a result, many non U.S.
               securities may be less liquid and their prices may be more
               volatile than U.S. securities.

               EMERGING SECURITIES MARKETS -- To the extent that the Acquiring
               Fund invests in countries with emerging markets, the non-U.S.
               securities risks are magnified since these countries may have
               unstable governments and less established markets.

     -  SECURITIES LENDING -- There is the risk that when lending portfolio
        securities, the securities may not be available to the Acquiring Fund on
        a timely basis and the Acquiring Fund may, therefore, lose the
        opportunity to sell the securities at a desirable price.

*    The redemption fee applies only to those shares that an investor held for
     four months or less. The fee is payable to the Acquired Fund and is
     intended to benefit the remaining shareholders by reducing the costs of
     short-term trading. The Acquired Fund's transfer agent also charges a $15
     redemption fee.

The Acquiring Fund has arrangements with its brokers, custodians, and third
party service providers whereby commissions paid by the Acquiring Fund, interest
earned on cash maintained with its custodian and income from securities lending
arrangements are used to reduce Acquiring Fund expenses and offset fees. These
arrangements will have no effect on the amount of fees that Nicholas-Applegate
must waive or expenses that it must otherwise reimburse under the Expense
Limitation Agreement through November 2006. If these expense reductions and fee
offsets are taken into account, "Total Annual Fund Operating Expenses" and "Net
Expenses" would be as follows:

*    Duncan-Hurst Capital Management has contractually agreed to reduce it fees
     and/or pay expenses of the Acquired Fund for at least the period show in
     the Example below and for an indefinite period thereafter to ensure the
     Total Annual Fund Operating Expenses will not exceed the net annual
     operating expenses amount shown. Duncan-Hurst Capital Management reserves
     the right under circumstances to be reimbursed for any waiver of its fees
     or expenses paid on behalf of the Acquired Fund if the Acquired Fund's
     expenses are less than the limit agreed to by the Acquired Fund. This
     contract may be terminated by the Board at any time.

**   Nicholas-Applegate has contractually agreed to waive or defer its

     Acquiring Fund if the Acquiring Fund's expenses are less than 1.25%.
     Nicholas-Applegate may not amend the fee waiver agreement without the
     consent of the Acquired Fund Board of Trustees.

EXAMPLE OF EFFECT OF FUND EXPENSES

     The following Example is intended to help you compare the cost of investing
the Acquiring Fund assuming Acquired Fund shareholders approve the
Reorganization.

     An investor in the Acquired Fund or the Acquiring Fund would pay the
following expenses on a $10,000 investment, assuming (1) 5% annual return, (2)
investment for the time periods indicated (3) reinvestment of all dividends and
other distributions, (4) the Fund's operating expenses are the same and (5)
redemption of all shares at the end of the following periods. Although your
actual costs may be higher or lower, based on these assumptions, your costs
would be:

</Table>

PURCHASES

     The purchase, redemption, and exchange privileges for the Acquiring Fund
and the Acquired Fund are similar in many respects but there are some
differences. Shares of the Acquired Fund and the Acquiring Fund are sold on a
continuous basis at the net asset value per share ("NAV") next computed after
receipt of a purchase order in good form. The NAV of both Funds is determined
each day that the New York Stock Exchange is open as of the close of regular
trading. Shares of both Funds may be purchased by wire transfer, telephone
exchange, or check by mail. The minimum initial investment in the Acquiring Fund
is $250,000 and the minimum subsequent investment is $10,000; the minimum
initial investment in the Acquired Fund is $25,000 and the minimum subsequent
investment is $1,000. However, the minimum investment requirements for the
Acquiring Fund will be waived for existing shareholders of the Acquired Fund who
transfer their accounts(s) to the Acquiring Fund as a part of the
Reorganization. Moreover, the minimum investment requirements for the Acquiring
Fund may be waived for purchases of shares made by current or retired trustees,
members, officers, and employees of the Nicholas-Applegate Institutional Funds,
Nicholas-Applegate Securities, LLC, Nicholas-Applegate, and its affiliates,
certain family members of the above persons, and trusts or plans primarily for
such persons or former employees thereof.

REDEMPTIONS

     Shares of both Funds may be redeemed at the option of shareholders by wire
transfer, telephone exchange, or check by mail. Redemptions are made at the NAV
per share next determined after a request in proper form is received at the
offices of each Fund. However, the Acquired Fund imposes a 2% redemption fee on
shares redeemed within four months of purchase. If shares of the Acquiring Fund
are purchased with a check that has not yet cleared, payment will be delayed
until after the check has cleared. The maximum amount that may be redeemed by
phone from the Acquiring Fund is $50,000. Both Funds reserve the right to make
payment wholly or partly in securities with a market value equal to the
redemption price.

                                        9
<Page>

EXCHANGES

     Shares of the Acquiring Fund may be exchanged on any business day for
shares of any other available fund within the Nicholas-Applegate Institutional
Funds at the NAV next determined after a request in proper form is received at
the offices of the Acquiring Fund. Shares of the Acquired Fund have no exchange
privileges with any other fund managed by Nicholas-Applegate.

DIVIDENDS AND OTHER DISTRIBUTIONS

     Each Fund earns investment income in the form of dividends and interest on
investments. Each Fund pays dividends based solely on its investment income.
Each Fund's policy is to annually distribute most or all of its net earnings in
the form of dividends to its shareholders, at the discretion of each Fund's
respective Board. Dividends are automatically reinvested in additional shares of
the distributing Fund at the NAV per share on the payable date unless otherwise
requested.

     Each Fund also realizes capital gains and losses when it sells securities
for more or less than it paid. If a Fund's total gains on these sales exceed
total losses thereon (including losses carried forward from previous years), the
Fund has net capital gains. Net realized capital gains, if any, are distributed
to each Fund's shareholders at least annually, usually in November or December.
Capital gain distributions are automatically reinvested in additional shares of
the distributing Fund on the payable date unless otherwise requested.

               VOTING ITEMS: AGREEMENT AND PLAN OF REORGANIZATION

DESCRIPTION OF THE REORGANIZATION AGREEMENT

     The terms and conditions under which the Reorganization will be consummated
are set forth in the Agreement and Plan of Reorganization which is attached as
Exhibit A (the "Reorganization Agreement"). Significant provisions of the
Reorganization Agreement are summarized below; however, this summary is
qualified in its entirety by reference to the Reorganization Agreement.

     The Reorganization Agreement provides that at the Closing Date the
Acquiring Fund will acquire substantially all of the property and assets of the
Acquired Fund in exchange solely for Class I shares of the Acquiring Fund and
the Acquiring Fund's assumption of all liabilities of the Acquired Fund.

     In exchange for the transfer to the Acquiring Fund of the Acquired Fund's
assets, the Acquiring Fund will simultaneously issue at the Closing Date full
and fractional Acquiring Fund Class I shares to the Acquired Fund for
distribution PRO RATA by the Acquired Fund to its shareholders. The number of
Acquiring Fund Class I shares so issued by the Acquiring Fund will have an
aggregate net asset value equal to the value of the net assets of the Acquired
Fund on the Closing Date.

     Following the close of business on the Closing Date, the Acquired Fund will
distribute PRO RATA to its shareholders the Acquiring Fund Class I shares
received by the Acquired Fund in liquidation thereof. Each shareholder owning
Acquired Fund Shares at the Closing Date will receive an amount of the
corresponding Acquiring Fund Class I shares equal to the value of their Acquired
Fund Shares.

     The Reorganization is subject to a number of conditions, including, among
other things: (a) approval of the Reorganization Agreement and the transactions
contemplated thereby, as described in this Statement, by the Acquired Fund's
shareholders; (b) the receipt of certain legal opinions of the Reorganization
Agreement (which include a legal opinion that the Acquiring Fund shares issued
to Acquired Fund shareholders in accordance with the terms of the Reorganization
Agreement will be validly issued, fully paid, and non-assessable and a legal
opinion that the Reorganization will not give rise to the recognition of income,
gain, or loss for federal income tax purposes to any Acquired Fund of Acquiring
Fund; (c) the receipt of certain certificates from the parties concerning the
continuing accuracy of the representations and warranties in the Reorganization
Agreement and other matters; and (d) the parties' performance of their
respective agreements and undertakings in the Reorganization Agreement. Assuming
satisfaction of the conditions in the Reorganization Agreement, the Closing Date
will be on November 18, 2005, or such other date as is agreed to by the parties.

                                       10
<Page>

     The Reorganization Agreement provides that Nicholas-Applegate shall be
responsible for the payment of all reasonable expenses incurred in connection
with entering into and carrying out the Reorganization (which expenses include
the fees and disbursements of attorneys and auditors and proxy printing and
solicitation expenses).

     The Reorganization Agreement and the Reorganization described herein may be
abandoned at any time prior to the Closing Date by the mutual consent of the
parties to the Reorganization Agreement. In such event, there shall be no
liability for damages on the part of any Fund, or its respective Board of
Trustees or officers, but Nicholas-Applegate shall bear all expenses incidental
to the preparation and carrying out of the Reorganization Agreement. The
Reorganization Agreement provides further that at any time prior to or after
approval of the Reorganization Agreement by the Acquired Fund's shareholders,
the Acquired Fund and Acquiring Fund, by written agreement, may amend, modify,
or supplement the Reorganization Agreement. The Reorganization Agreement further
provides that no such amendment, modification, or supplement may have the effect
of changing the provisions for determining the number of Acquiring Fund Shares
to be distributed to Acquired Fund shareholders under the Reorganization
Agreement to the detriment of the Acquired Fund shareholders, unless the
Acquired Fund shareholders approve such change or unless the amendment merely
changes the Closing Date.

REASONS FOR THE REORGANIZATION

     The predecessor investment adviser to the Acquired Funds, Duncan-Hurst
Capital Management ("Duncan-Hurst") and the investment adviser to the Acquiring
Funds, Nicholas-Applegate Capital Management ("Nicholas-Applegate"), had entered
into an Asset Purchase Agreement, dated June 30, 2005 that, in addition to the
duties and responsibilities described in the Reorganization Agreement also
memorializes the proposed remuneration to be received by Duncan-Hurst in
connection with the proposed transaction. The acquisition by Nicholas-Applegate
of the rights to manage Duncan-Hurst Capital management's international assets
was mutually agreed upon by each company to enhance Nicholas-Applegate's
international equity capabilities while Duncan-Hurst Capital Management will
continue to focus on its core strength in the management of U.S. growth
equities. Nicholas-Applegate and Duncan-Hurst Capital Management each share a
similar heritage of growth stock investing and trace their roots back to pacific
Century Advisers, a subsidiary of Security Pacific Bank. Both companies received
financial benefits from this agreement. As consideration for the assets to be
acquired, Nicholas-Applegate has agreed to pay a portion of its investment
management fees to Duncan-Hurst earned on assets invested in international
all-cap growth and international small cap growth strategies until June 30,
2010. This transaction enabled Duncan-Hurst to exit the business of managing
international growth assets and concentrate its resources on managing US assets.

     Based on their evaluation of the relevant information presented to them,
and in light of their fiduciary duties under federal and state law, the Board
has unanimously determined that the proposed Reorganization is in the best
interest of the shareholders, that the terms are fair and reasonable, and the
interests of the Acquired Fund's shareholders will not be diluted as a result of
the Reorganization. Accordingly, the Board recommends the approval of the
Reorganization Agreement by such shareholders at the Special Meeting. In
approving the Reorganization, the Board, including a majority of the Independent
Trustees, considered a number of factors, including the following:

     (1)  there would be no change in the investment adviser,
          Nicholas-Applegate, and the portfolio management team;

     (2)  the similarity of the Acquiring Fund's investment objectives,
          policies, risks and restrictions with those of the Acquired Fund and
          the fact that the two Funds are duplicative;

     (3)  expense ratios and information regarding fees and expenses of the
          Acquired Fund and the Acquiring Fund, including the planned expense
          limitation arrangements offered by Nicholas-Applegate and the fact
          that existing shareholders would experience a significant reduction in
          Acquired Fund operating expenses;

     (4)  the effect of the Reorganization on the Acquired Fund's ability to
          attract new investment;

     (5)  the terms and conditions of the Reorganization, whether it is in the
          best interests of the Acquired Fund shareholders and whether it would
          result in a dilution of the interest of current shareholders;

                                       11
<Page>

     (6)  the fact that Duncan-Hurst Capital Management has determine that it
          does not want to continue to engage in the management of international
          assets and wants to focus on U.S. equity management for institutional
          clients, so that in any event Duncan-Hurst Capital Management would no
          longer be available to manage the Acquired Fund and that in
          furtherance of this goal Duncan-Hurst Capital Management has entered
          into an Asset Purchase Agreement with Nicholas-Applegate to sell
          certain assets related to the management of the Acquired Fund;

     (7)  Nicholas-Applegate's commitment to pay for the expenses of the
          Reorganization;

     (8)  the tax free-free nature of the Reorganization to Acquired Fund and
          its shareholders.

     Similarly, at meetings of the Board of Trustees of Nicholas-Applegate
Institutional Funds held on August 12, 2005, the Board of Trustees of the
Acquiring Fund considered the proposed Reorganization with respect to the
Acquiring Funds. Based on their evaluation of the relevant information provided
to them, and in light of their fiduciary duties under federal and state law, the
Board of Trustees unanimously determined that (a) the proposed Reorganization
would be in the best interests of the Nicholas-Applegate Institutional Funds and
their shareholders, and (b) the interests of the existing shareholders will not
be diluted as a result of the proposed Reorganization.

DESCRIPTION OF THE SECURITIES TO BE ISSUED

     The Nicholas-Applegate Institutional Funds are registered with the
Securities and Exchange Commission as an open-end management investment company.
The Acquiring Fund is a series of the Nicholas-Applegate Institutional Funds.
Shares of the Acquiring Fund entitle their holders to one vote per full and
fractional votes for fractional shares held. If shareholders approve the
Reorganization, each shareholder of the Acquired Fund will receive Class I
Shares of the Acquiring Fund equal in value.

FEDERAL INCOME TAX CONSEQUENCES

     Consummation of the Reorganization is subject to the condition that the
Funds receive an opinion from counsel, substantially to the effect that, based
upon certain facts, assumptions and representations, the transactions
contemplated by the Reorganization Agreement with respect to the Acquired Fund
and the Acquiring Fund constitute a tax-free reorganization for federal income
tax purposes. The delivery of such opinion is conditioned upon receipt by
counsel of representations it shall request of the Professionally Managed
Portfolios and the Nicholas-Applegate Institutional Funds.

     The Funds have not sought a tax ruling from the Internal Revenue Service
("IRS"). The opinion of counsel is not binding on the IRS and does not preclude
the IRS from adopting a contrary position. Shareholders should consult their own
tax advisers concerning the potential tax consequences to them, including state
and local income tax consequences.

     As of March 31, 2005, the Acquired Fund had accumulated capital loss
carryforwards in the amount of approximately $11,807,324. After the
Reorganization, these losses will be available to the Acquiring Fund to offset
capital gains, although the amount of these losses which might offset the
Acquiring Fund's capital gains may be limited. As a result, of this limitation,
it is possible that the Acquiring Fund may not be able to use these losses as
rapidly or to the same extent as the Acquired Fund might have. In addition, the
benefits of any capital loss carryforwards currently are available only to
shareholders of the Acquired Fund. After the Reorganization, however, these
benefits will inure to benefit of all shareholders of the Acquiring Fund.

CAPITALIZATION

     Because the Acquired Fund will be combined in the Reorganization with the
Acquiring Fund, the total capitalization of the Acquiring Fund after the
Reorganization is expected to be negligibly higher than the current

                                       12
<Page>

capitalization of the Acquired Fund. The following table sets forth as of
September 30, 2005 (unaudited): (i) the capitalization of the Acquired Fund;
(ii) the capitalization of the Acquiring Fund; and (iii) the pro forma
capitalization of the Acquiring Fund as adjusted to give effect to the
Reorganization. If the Reorganization is consummated, the capitalization of the
Acquiring Fund is likely to be different at the Closing Date as a result of
daily share purchase and redemption activity in the Acquired Fund and the
Acquiring Fund.

INFORMATION RELATING TO VOTING MATTERS

     This Statement is being furnished in connection with the solicitation of
proxies by the Board in connection with the Special Meeting. It is expected that
the solicitation of proxies will be primarily by mail. Officers and service
providers of the Professionally Managed Portfolios and Nicholas-Applegate may
also solicit proxies by telephone, fax, or personal interview. Any shareholder
giving a proxy may revoke it at any time before it is exercised by submitting to
the Acquired Fund a written notice of revocation or a subsequently executed
proxy or by attending the Special Meeting and voting in person.

     Only shareholders of record at the close of business on October 12, 2005,
will be entitled to vote at the Special Meeting. On that date there were
outstanding and entitled to vote shares. Each share or fraction thereof is
entitled to one vote or fraction thereof.

     If the accompanying proxy is executed and returned in time for the Special
Meeting, the shares covered thereby will be voted in accordance with the proxy
on all matters that may properly come before the Special Meeting or any
adjournment of the Special Meeting. For information on adjournment of the
Special Meeting, see "Quorum" below.

OUTSTANDING SHARES

     As of Record Date, the name, address, and share ownership of the persons
who beneficially owned 5% or more of the Acquired Fund's outstanding shares, and
the percentage of shares that would be owned by such persons upon consummation
of the Reorganization based upon their holdings and outstanding shares at Record
Date are as follows:

SHAREHOLDER AND BOARD APPROVALS

     The Reorganization Agreement (and the transactions contemplated thereby) is
being submitted at the Special Meeting for approval by the shareholders of the
Acquired Fund. The approval of the holders of a "majority" of the outstanding
Acquired Fund Shares is required for the approval of the Reorganization with
respect to the Acquired Fund, in accordance with the provisions of the
Declaration of Trust of the Professionally Managed Portfolios. Under the 1940
Act, a "majority" is the lesser of (i) 67% or more of the Acquired Fund Shares
present or represented by proxy at the Special Meeting, if more than 50% of the
Acquired Fund Shares are present or represented by proxy; or (ii) more than 50%
of the total outstanding Acquired Fund Shares. Abstentions will have the same
effect as casting a vote against the relevant Proposal.

     The vote of the shareholders of the Acquiring Fund is not being solicited
because their approval or consent is not required for the Reorganization to be
consummated.

QUORUM

     A quorum is constituted by the presence in person or by proxy of the
holders of more than 40% of the outstanding shares of the Acquired Fund. In the
event that a quorum is not present at the Special Meeting, or in the event that
a quorum is present at the Special Meeting but sufficient votes to approve the
Reorganization Agreement and the transactions contemplated thereby are not
received, the persons named as proxies may propose one or more adjournments of
the Special Meeting to permit further solicitation of proxies. Any such
adjournment will require the affirmative vote of a majority of those shares
affected by the adjournment that are represented at the Special Meeting in
person or by proxy. If a quorum is present, the persons named as proxies will
vote those proxies that they are entitled to vote FOR the Reorganization
Agreement in favor of such adjournments, and will vote those proxies required to
be voted AGAINST such proposal against any adjournment. Proxies properly
executed and marked with a negative vote or an abstention, or broker non-votes,
will be considered to be present at the Special Meeting for the purposes of
determining the existence of a quorum for the transaction of business. Broker
non-votes exist where a broker proxy indicates that the broker is not authorized
to vote on a particular proposal.

                     ADDITIONAL INFORMATION ABOUT EACH FUND

THE TRUSTS: MASSACHUSETTS BUSINESS TRUST VERSUS DELAWARE BUSINESS TRUST

     The Professionally Managed Portfolios is a Massachusetts business trust,
and Nicholas-Applegate Institutional Funds is organized as a Delaware business
trust. The two forms of organization are very similar. For example, the
responsibilities, powers and fiduciary duties of the Board of Trustees of
Nicholas-Applegate Institutional Funds are substantially the same as those of
the Board. However, the Delaware Business Trust Act ("DBTA") affords business
trusts definable rights and protections by virtue of its terms having been set
forth in the statute, and in some important respects is deemed to have expanded
the protections afforded by the business trust. If the Reorganization is
approved and the transfer of assets takes place, shareholders of the Acquired
Fund will have the benefit of various provisions that either do not exist or are
not explicit under the laws governing entities organized as Massachusetts
business trusts. For example, while the risk of shareholder liability is not
great, the DBTA appears to provide shareholders with greater protection from
liabilities incurred by a business trust organized under the DBTA.

     The specific differences between the Professionally Managed Portfolios and
Nicholas-Applegate Institutional Funds are discussed below. The operations of
the Professionally Managed Portfolios, as a Massachusetts business, are governed
by its Declaration of Trust and Bylaws ("Professionally Managed Portfolios'
Declaration of Trust") and Massachusetts law, while the operations of
Nicholas-Applegate Institutional Funds are governed by its Amended and Restated
Declaration of Trust and Bylaws ("NA Funds' Declaration of Trust") and Delaware
law.

LIABILITY OF SHAREHOLDERS

     Under Massachusetts law, shareholders of the Professionally Managed
Portfolios may, under certain circumstances, be held personally liable as
partners for the Professionally Managed Portfolios' obligations.

                                       14
<Page>

However, the risk of a shareholder incurring financial loss as a result of
shareholder liability is limited to circumstances in which both inadequate
insurance exists and the Professionally Managed Portfolios, itself, is unable to
meet its obligations. The Professionally Managed Portfolios' Declaration of
Trust specifically states that no shareholder shall be personally liable to any
person in connection with the Professionally Managed Portfolios' property or the
acts, obligations or affairs of the Professionally Managed Portfolios. The
Professionally Managed Portfolios' Declaration of Trust further states that the
Professionally Managed Portfolios shall indemnify and hold each shareholder
harmless from and against all loss and expense to which the shareholder may
become subject by reason of his being or having been a shareholder.

     Under the DBTA, on the other hand, shareholders of a Delaware business
trust are entitled to the same limitations of liability extended to shareholders
of private for-profit corporations. As such, there is a possibility, albeit
remote, that under certain circumstances shareholders of a Delaware business
trust may be held personally liable for a Delaware business trust's obligations.
This might occur if the courts of another state not recognizing the limitation
on liability were to apply the laws of the state to a controversy involving the
Delaware business trust's obligations. To protect against such an occurrence,
the NA Funds' Declaration of Trust provides that Nicholas-Applegate
Institutional Funds shall indemnify and hold each of Nicholas-Applegate
Institutional Funds' shareholders harmless from and against any claim or
liability to which the shareholder may become subject solely by reason of his or
her being or having been a shareholder, and that was not due to the
shareholder's acts or omissions or for some other reason. In such an instance,
Nicholas-Applegate Institutional Funds will reimburse the shareholder for all
legal and other expenses reasonably incurred by him or her in connection with
any such claim or liability. Thus, the risk of a shareholder incurring financial
loss beyond his or her investment due to shareholder liability is limited to
circumstances in which Nicholas-Applegate Institutional Funds itself is unable
to meet its obligations.

ELECTION OF TRUSTEES; SHAREHOLDER MEETINGS

     Neither Massachusetts business trust law nor the DBTA require investment
companies to hold annual meetings of shareholders. The shareholders of both the
Acquired Funds and the Acquiring Funds may, from time to time, be entitled to
vote for the election of trustees in elections that are held as required by the
1940 Act, the Declaration of Trust or the Bylaws. The NA Funds' Declaration of
Trust provides that shareholders' meetings may be called at any time by a
majority of the trustees and shall be called by any trustee upon written request
of shareholders holding, in the aggregate, not less than 10% of the issued and
outstanding shares of beneficial interest. Shareholder requests for a meeting
must specify the purpose or purposes for which the meeting is to be called.

VOTING RIGHTS OF SHAREHOLDERS

     The Professionally Managed Portfolios' Declaration of Trust grants
shareholders the power to vote only with respect to: (i) the election of
trustees; (ii) approval of any investment advisory contract; (iii) the
termination of the Professionally Managed Portfolios or any series of the
Professionally Managed Portfolios; (iv) any amendment of the Professionally
Managed Portfolios' Declaration of Trust, (v) approval of any merger,
consolidation or sale of assets, (vi) the incorporation of the Professionally
Managed Portfolios; (vii) whether or not a court action, proceeding or claim
should or should not be brought or maintained derivatively or as a class action
on behalf of the Professionally Managed Portfolios or a series of the

INTERNATIONAL ALL CAP GROWTH FUND

[GRAPHIC]

GOAL AND PRINCIPAL STRATEGY

The Fund seeks maximum long-term capital appreciation. In pursuing this goal,
the Fund invests in a diversified portfolio of equity securities of companies
primarily located in developed non-U.S. markets.

The Investment Adviser conducts "bottom-up" individual company analysis on a
group of companies that meet the Investment Adviser's standards. It identifies
companies experiencing accelerating earnings, rising relative price strength and
positive company fundamentals. A "top-down" analysis is conducted to confirm the
results of "bottom-up" scrutiny, and help identify the most attractive sectors
and countries for investment. The resulting portfolio is invested in companies
with above average earnings growth and positioned in strong growth areas,
typically in as many as fifteen to twenty-five countries outside of the U.S. The
Fund will invest in companies of any size from larger, well-established
companies to smaller, emerging growth companies, and may invest in companies in
lesser-developed countries.

The Fund may also lend portfolio securities on a short-term basis, up to 30% of
its total assets.

The Fund may invest in various Depositary Receipts traded on domestic and
foreign exchanges, as well as foreign securities traded on the U.S. securities
market. The Fund may also invest up to 15% of its net assets in equity-linked
securities.

[GRAPHIC]

PRINCIPAL INVESTMENTS

The Fund normally invests at least 75% of its net assets in common stocks. Under
normal conditions, the Fund invests at least 80% of its net assets in the
securities of companies that are tied economically to a number of different
countries throughout the world. The Fund's investments are not limited with
respect to the capitalization size of issuers. The Fund will provide
shareholders with at least 60 days' prior notice of any change in this
investment policy. The Fund may invest up to 20% of its assets in U.S.
companies.

[GRAPHIC]

PRIMARY RISKS

Because you could lose money by investing in the Fund, be sure to read all risk
disclosures carefully before investing. The Fund is primarily subject to the
following risks:

- -   Stock Market Volatility--The prices of equity securities change in response
    to many factors, including the historical and prospective earnings of the
    issuer, its market capitalization, the value of its assets, general economic
    conditions, interest rates, investor perceptions, domestic and worldwide
    political events, and market liquidity. Stock prices are unpredictable, may
    fall suddenly and may continue to fall for extended periods.

- -   NON-U.S. SECURITIES RISKS--The prices of non-U.S. securities may be further
    affected by other factors, including:

      CURRENCY EXCHANGE RATES--The dollar value of the Fund's non-U.S.
      investments will be affected by changes in the exchange rates between the
      dollar and the currencies in which those investments are traded.

      POLITICAL AND ECONOMIC CONDITIONS--The value of the Fund's non-U.S.
      investments may be adversely affected by political and social instability
      in their home countries and by changes in economic or taxation policies in
      those countries.

      REGULATIONS--Non-U.S. companies generally are subject to less stringent
      regulations, including financial and accounting controls, than are U.S.
      companies. As a result, there generally is less publicly available
      information about non-U.S. companies than about U.S. companies.

      MARKETS--The securities markets of other countries are smaller than U.S.
      securities markets. As a result, many non-U.S. securities may be less
      liquid and their prices may be more volatile than U.S. securities.

- -   SECURITIES LENDING--There is the risk that when lending portfolio
    securities, the securities may not be available to the Fund on a timely
    basis and the Fund may, therefore, lose the opportunity to sell the
    securities at a desirable price.

- -   ACTIVE PORTFOLIO TRADING--A high portfolio turnover rate has the potential
    to generate more taxable short-term gains that may be taxed as ordinary
    income and may have an adverse effect on the Fund's after tax performance.

See "Principal Strategies, Risks and Other Information" starting on page
(update).

INVESTOR FEES AND EXPENSES

As an investor, you pay certain fees and expenses in connection with the Fund,
which are described in the table below. Annual Fund Operating Expense are paid
out of the Fund assets, so their effect is included in the share price. The Fund
has no sales charge (load) or 12b-1 distribution fees.

<Table>

Management fee                                  0.95%
Distribution fee (12b-1 fee)                    None
Other expenses+                                 __%
   Administrative Services Fee                  0.15%
   Shareholder Services Fee                     0.15%
Total Annual Fund Operating Expenses            1.81%
Waiver of Fund Expenses                         (0.56)%
NET EXPENSES                                    1.25%
</Table>

+ THE FUND'S "OTHER EXPENSES" ARE ESTIMATED AMOUNTS FOR THE CURRENT FISCAL YEAR.

THE FUND REDUCES EXPENSES BY A PORTION OF THE BROKERAGE COMMISSIONS PAID BY IT
AND BY OFFSETS TO CUSTODIAL AND OTHER FEES BASED UPON THE AMOUNT OF SECURITIES
LENT TO THIRD PARTIES AND CASH MAINTAINED WITH ITS CUSTODIAN. IF THESE EXPENSE
REDUCTIONS AND FEE OFFSETS ARE TAKEN INTO ACCOUNT, "TOTAL ANNUAL FUND OPERATING
EXPENSES" AND "NET EXPENSES" WOULD BE 1.56% AND 1.00%, RESPECTIVELY.

THE INVESTMENT ADVISER HAS CONTRACTUALLY AGREED TO WAIVE ITS MANAGEMENT FEES AND
TO REIMBURSE OTHER OPERATING EXPENSES OTHERWISE PAYABLE BY THE FUND THROUGH
3/31/06. THE INVESTMENT ADVISER MAY NOT AMEND THE FEE WAIVER AGREEMENT WITHOUT
THE CONSENT OF THE FUND. SEE "EXPENSE WAIVERS" ON PAGE (UPDATE).

THE FOLLOWING EXAMPLE IS INTENDED TO HELP YOU COMPARE THE COST OF INVESTING IN
THE FUND WITH THE COST OF INVESTING IN OTHER MUTUAL FUNDS. THE EXAMPLE ASSUMES
THAT YOU INVEST $10,000 IN THE FUND'S SHARES FOR THE TIME PERIODS INDICATED AND
REDEEM ALL OF YOUR SHARES AT THE END OF THOSE PERIODS. THE EXAMPLE ALSO ASSUMES
THAT YOUR INVESTMENT HAS A 5% RETURN EACH YEAR AND THAT THE FUND'S OPERATING
EXPENSES ARE AFTER WAIVERS, IF ANY, FOR THE 1 YEAR PERIOD AND BEFORE WAIVERS, IF
ANY, FOR THE OTHER PERIODS SHOWN. ALTHOUGH YOUR ACTUAL COSTS MAY BE HIGHER OR
LOWER, BASED ON THESE ASSUMPTIONS YOUR COSTS WOULD BE:

<Table>

</Table>

THE EXAMPLE ABOVE DOES NOT TAKE INTO ACCOUNT ANY OFFSET ARRANGEMENTS THAT THE
FUND WILL ENTER INTO WITH ITS BROKERS, CUSTODIANS AND THIRD PARTY SERVICE
PROVIDERS. IF THE OFFSET CREDITS DESCRIBED WERE APPLIED TO THE ABOVE EXAMPLE,
YOUR COST FOR THE 1 AND 3 YEAR PERIODS WOULD BE $105 AND $458, RESPECTIVELY.

                                      If you purchased shares through a financial representative
                                      or plan administrator/sponsor, you should call them
                                      regarding the most efficient way to sell shares. If you

                                      days from the date of purchase. Sales by a corporation,
                                      trust or fiduciary may have special requirements. Please

                                      administrator/sponsor or us for further information.

YOUR ACCOUNT

TRANSACTION POLICIES

PURCHASE OF SHARES. Shares are offered at net asset value without a sales
charge. The minimum initial investments for opening an individual account is
$250,000.

Certain omnibus accounts may not combine the assets of the underlying investor
in order to satisfy the investment minimum. In addition, the Investment Adviser
may take into account the aggregate assets that the shareholder has under
management with the Investment Adviser. The minimum investment may be waived for
purchases of shares made by current or retired directors, trustees, partners,
officers and employees of Nicholas-Applegate Institutional Funds (the "Trust"),
the Distributor, the Investment Adviser and its affiliates, certain family
members of the above persons, and trusts or plans primarily for such persons or
former employees employed by one of its affiliates, or, at the discretion of the
Distributor. Eligibility for different classes of the Fund depends upon the
shareholder meeting either (i) the investment minimums set forth above, (ii) the
total market value of all the shareholder's assets managed by the Investment
Adviser and its affiliates or (iii) what the Investment Adviser and shareholder
may negotiate at arm's length. The Fund may only accept orders for shares in
states where it is legally able to offer shares.

The Fund may discontinue sales of its shares if the Investment Adviser and the
Trustees believe that continued sales may adversely affect the Fund's ability to
achieve its investment objective. If sales of a Fund's shares are discontinued,
it is expected that existing shareholders invested in the Fund would be
permitted to continue to authorize investment in the Fund and to reinvest any
dividends or capital gains and distributions, absent highly unusual
circumstances.

ANTI-MONEY LAUNDERING PROGRAM. The Fund is required to comply with various
federal anti-money laundering laws and regulations. Consequently, the Fund may
be required to "freeze" the account of a shareholder if the shareholder appears
to be involved in suspicious activity or if certain account information matches
information on government lists of known terrorists or other suspicious persons,
or the Fund may be required to transfer the account or proceeds of the account
to a government agency. The Fund may also be required to reject a purchase
payment, block a shareholder's account and consequently refuse to implement
requests for transfers and withdrawals.

Federal law requires the Fund to obtain, verify and record identifying
information, which may include the name, street address, taxpayer identification
number or other identifying information from shareholders who open an account
with the Fund. The Fund may also ask to see a shareholder's driver's license or
other identifying documents. Applications without this information may be
rejected and orders may not be processed. The Fund reserves the right to place
limits on transactions in any account until the identity of the shareholder is
verified; to refuse an investment in the Fund or involuntarily redeem a
shareholder's shares and close an account in the event that a shareholder's
identity is not verified within 5 days of the purchase; or suspend the payment
of withdrawal proceeds if it is deemed necessary to comply with anti-money
laundering regulations. An involuntary redemption may result in an unfavorable
tax consequence or loss of principal. The Fund and its agents will not be
responsible for any loss resulting from the shareholder's delay in providing all
required identifying information or from closing an account and redeeming a
shareholders share when a shareholder's identity cannot be verified.

PRICING OF SHARES. The net asset value per share ("NAV") of the Fund is
determined each business day at the close of regular trading on the New York
Stock Exchange (usually 4 p.m. Eastern time) by dividing the value of the Fund's
net assets by the number of its shares outstanding.

Securities traded in non-U.S. countries may not take place on all business days
of the New York Stock Exchange, and may occur in various non-U.S. markets on
days which are not business days of the New York Stock Exchange. Accordingly,
the Fund's NAV may change on days when the U.S. markets are closed whereby a
shareholder of the Fund will not be able to sell their shares.

NAV is based on the market value of the securities in the Fund's portfolio,
equity holdings are valued on the basis of market quotations or official
closing prices. If market quotations, official closing prices are not readily
available, or are determined not to reflect accurately fair value (such that
when the value of a security has been materially affected by events occurring
after the close of the exchange or market on which the security is
principally traded (for example a foreign exchange or market), but before the
Fund calculates its NAV), the Investment Adviser will value the security at
fair value in accordance with procedures approved by the Fund's Board of
Trustees. Under such procedures, the Investment Adviser will fair value when,
in its opinion, publicly available prices are no longer readily available, or
are no longer reliable. Such circumstances would include when trading in the
security is halted, when an entire market is closed, or when the movement of
the markets in the U.S. reach certain trigger points. Fair value of
securities will be determined by the Investment Adviser's pricing committee
in good faith using such information as it deems appropriate under the

                                        6
<Page>

circumstances. Fair value of foreign equity securities may be determined with
the assistance of a pricing service using correlations between the movement
of prices of foreign securities and indexes of domestic securities and other
appropriate indicators, such as closing market prices of relevant ADRs and
futures contracts. Using fair value to price securities may result in a value
that is different from a security's most recent closing price and from the
prices used by other mutual funds to calculate their net asset values.
Foreign securities may trade on days when the Fund does not calculate its NAV
and thus may affect the Fund's NAV on days when shareholders will not be able
to purchase or redeem Fund shares.

BUY AND SELL PRICES. When you buy shares, you pay the NAV, as described earlier.
When you sell shares, you receive the NAV. Your financial institution may charge
you a fee to execute orders on your behalf.

EXECUTION OF REQUESTS. The Fund is open on the days the New York Stock Exchange
is open, usually Monday-Friday. Buy and sell requests are executed at the NAV
next calculated after your request is received in good order by the transfer
agent or another agent designated by the Fund. The Fund reserves the right to
refuse any purchase order.

The Fund reserves the right to reject any purchase or to suspend or modify the
continuous offering of its shares. Your financial representative is responsible
for forwarding payment promptly to the transfer agent. The Fund reserves the
right to cancel any buy request if payment is not received within three days.

In unusual circumstances, the Fund may temporarily suspend the processing of
sell requests, or may postpone payment of proceeds for up to seven days or
longer, as allowed by federal securities laws.

PURCHASE OF SHARES JUST BEFORE RECORD DATE. If you buy shares of the Fund just
before the record date for a distribution (the date that determines who receives
the distribution), the Fund will pay that distribution to you. When a
distribution is paid, the value of each share of the Fund decreases by the
amount of the distribution to reflect the payout. The distribution you receive
makes up the decrease in share value. As explained under the Taxability of
Dividends section, the distribution may be subject to income or capital gains
taxes. The timing of your purchase means that part of your investment came back
to you as taxable income.

EXCHANGES. On any business day you may exchange all or a portion of your shares
for shares of any other available Fund of the same share class only if you are
eligible to purchase shares of such class.

MARKET TIMING. The Fund does not permit market timing or other excessive trading
practices which may disrupt portfolio management strategies and harm Fund
performance by diluting the value of portfolio shares and increasing brokerage
and administrative costs. To protect the interests of other shareholders in the
Fund, the Investment Adviser monitors trading activity and the Trust may cancel
the exchange privileges (or reject any exchange or purchase orders) of any
parties who, in the opinion of the Investment Adviser, are engaging in market
timing. For these purposes, the Trust may consider a shareholder's trading
history in the Funds. The Trust may change or cancel its exchange policies at
any time, upon 60 days' notice to its shareholders.

Because the Fund invests in markets throughout the world, it may be especially
susceptible to market timing if it allowed excessive trades that can take
advantage of the different times that overseas markets are open. The Board has
delegated responsibility for pricing securities and reviewing trading practices
to the Investment Adviser. These policies and procedures are applied
consistently to all shareholders. Although the Fund makes an effort to monitor
for market-timing activities, the ability of the Fund to monitor trades that are
placed by the underlying shareholders of omnibus accounts maintained by brokers,
retirement plan accounts and other approved intermediaries may be limited in
those instances in which the investment intermediary maintains the underlying
shareholder accounts. Accordingly, there can be no assurance that the Fund will
be able to eliminate all market-timing activities.

REDEMPTIONS IN KIND. When the Fund elects to satisfy a redemption request with
securities, the shareholder assumes the responsibility of selling the securities
as well as a market risk of an unfavorable market movement during the time
required to convert the securities to cash.

TELEPHONE TRANSACTIONS. For your protection, telephone requests may be recorded
in order to verify their accuracy. In addition the Fund will take measures to
verify the identity of the caller, such as asking for name, account number,
Social Security or taxpayer ID number and other relevant information. If these
measures are not taken, the Fund may be responsible for any losses that may
occur in your account due to an unauthorized telephone call.

At times of peak activity, it may be difficult to place requests by phone.
During these times, consider sending your request in writing.

CERTIFICATED SHARES. Shares of the Fund are electronically recorded. The Fund
does not normally issue certificated shares.

                                        7
<Page>

SALES IN ADVANCE OF PURCHASE PAYMENTS. When you place a request to sell shares
for which the purchase money has not yet been collected, the request will be
executed in a timely fashion, but the Fund will not release the proceeds to you
until your purchase payment clears. This may take up to fifteen calendar days
after the purchase.

FEATURES AND ACCOUNT POLICIES

The services referred to in this section may be terminated or modified at any
time upon 60 days' written notice to shareholders. Shareholders seeking to add
to, change or cancel their selection of available services should contact the
transfer agent.

RETIREMENT PLANS. You may invest in the Fund through various retirement plans,
including IRAs, Roth IRAs, Simplified Employee Plan (SEP) IRAs, 403(b) plans,
457 plans, and all qualified retirement plans. For further information about any
of the plans, agreements, applications and annual fees, contact the Distributor,
your financial representative or plan sponsor. To determine which retirement
plan is appropriate for you, consult your tax adviser.

ACCOUNT STATEMENTS. Shareholders will receive periodic statements reporting all
account activity, including systematic transactions, dividends and capital gains
paid.

ELECTRONIC DELIVERY. The Fund can deliver prospectuses, account statements,
transaction confirmations, and fund financial reports electronically. If you are
a registered user of NACM.com, you can consent to the electronic delivery of
these documents by logging on and changing your mailing preference under "My
Profile." You can revoke your electronic consent at any time, and the Fund will
begin to send paper copies of these documents within 30 days of receiving your
notice.

SEMI-ANNUAL REPORTS AND PROSPECTUSES. The Fund produces financial reports every
six months and updates its prospectus annually. To avoid sending duplicate
copies of materials to households, only one copy of the Trust's annual and
semi-annual report and prospectus will be mailed to shareholders having the same
residential address on the Trust's records. However, any shareholder may contact
the Distributor(see back cover for address and phone number) to request that
copies of these reports and prospectuses be sent personally to that shareholder.

DIVIDENDS. The Fund generally distribute most or all of its net earnings in the
form of dividends. The Fund pays dividends of net investment income annually.

Any net capital gains are distributed annually. Annual dividends and net capital
gains are normally distributed in the last calendar quarter.

DIVIDEND REINVESTMENTS. If you choose this option, or if you do not indicate any
choice, your dividends will be reinvested on the ex-dividend date.
Alternatively, you can choose to have a check for your dividends mailed to you.
Interest will not accrue or be paid on uncashed dividend checks.

TAXABILITY OF DIVIDENDS. Dividends you receive from the Fund, whether reinvested
or taken as cash, are generally taxable. Dividends from the Fund's long-term
capital gains are taxable as capital gains; dividends from other sources are
generally taxable as ordinary income.

Some dividends paid in January may be taxable as if they had been paid the
previous December. Corporations may be entitled to take a dividends-received
deduction for a portion of certain dividends they receive.

The tax information statement that is mailed to you details your dividends and
their federal tax category, although you should verify your tax liability with
your tax professional.

TAXABILITY OF TRANSACTIONS. Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions.

Federal tax law requires you to provide the Fund with your taxpayer
identification number and certifications as to your tax status. If you fail to
do this, or if you are otherwise subject to backup withholding, the Fund will
withhold and pay to the U.S. Treasury 31% of your distributions and sale
proceeds. Dividends of net investment income and short-term capital gains paid
to a nonresident non-U.S. shareholder generally will be subject to a U.S.
withholding tax of up to 30%. This rate may be lower, depending on any tax
treaty the U.S. may have with the shareholder's country.

SMALL ACCOUNTS. If you draw down a non-retirement account so that its total
value is less than the minimum investment, you may be asked to purchase more
shares within 60 days. If you do not take action, the Fund may close out your
account and mail you the proceeds. Your account will not be closed if its
drop in value is due to Fund performance. See "Automatic Share Conversion"
below.

AUTOMATIC INVESTMENT PLAN. You may make regular monthly or quarterly investments
in the Fund through automatic withdrawals of specified amounts from your

                                        8
<Page>

bank account once an automatic investment plan is established. See the
account application for further details about this service or call the Fund
at 1-800-551-8043.

AUTOMATIC SHARE CONVERSION. The account of any shareholder in any class shall be
automatically converted into the shares of a class of the Fund with a higher
shareholder account minimum if the shares in such account have a value equal to
or higher than such minimum as of the end of each calendar quarter. The account
of any shareholder in any class shall be automatically converted into the shares
of a class with lower shareholder account minimum if, by reason of the
redemption of shares, the value of the shares in such account is less than the
shareholder account minimum for the account's class as determined at the end of
each calendar quarter. All conversions pursuant to this paragraph shall be made
at the respective net asset values determined as of the end of the day in which
the account is converted.

The automatic conversion does not apply to omnibus accounts maintained by
intermediaries (e.g. sub transfer agents, record keepers, etc.) that have
revenue sharing arrangements with the Distributor or the Investment Adviser.

CROSS-REINVESTMENT. You may cross-reinvest dividends or dividends and capital
gains distributions paid by one Fund into another Fund,subject to conditions
outlined in the Statement of Additional Information and the applicable
provisions of the qualified retirement plan.

ORGANIZATION AND MANAGEMENT

THE INVESTMENT ADVISER

Investment decisions for the Fund are made by the Fund's Investment Adviser,
Nicholas-Applegate Capital Management (the "Investment Adviser"), subject to
direction by the Trustees. The Investment Adviser continually conducts
investment research and supervision for the Fund and is responsible for the
purchase or sale of portfolio instruments, for which it receives an annual fee
from the Fund. A discussion regarding the basis for the Board of Trustees
approving the Investment Advisory Agreement is available in the Funds' annual
report to shareholders dated March 31, 2005.

Founded in 1984, the Investment Adviser currently manages approximately $15
billion in discretionary assets for numerous clients, including employee benefit
plans, corporations, public retirement systems and unions, university
endowments, foundations, and other institutional investors and individuals. The
Investment Adviser's address is 600 West Broadway, Suite 2900, San Diego,
California 92101.

INVESTMENT ADVISER COMPENSATION

The Fund pays the Investment Adviser a monthly fee pursuant to an investment
advisory agreement. The Fund pays an advisory fee monthly at the annual rate of
___% its average net assets.

ADMINISTRATIVE SERVICES

The Investment Adviser provides the Fund with certain financial, legal,
compliance, shareholder communications and other administrative services
pursuant to an Administrative Services Agreement. Under this Agreement, the Fund
pays the Investment Adviser an Administrative fee of up to __% per annum of the
Fund's average daily net assets.

SHAREHOLDER SERVICES

The Fund has entered into a Shareholder Services Agreement with the Distributor
under which the Fund will pay the Distributor up to __% of the average daily
assets of the Fund to pay financial institutions, including the Investment
Adviser, for certain personal services for shareholders and for the maintenance
of shareholder accounts. The Investment Adviser may make additional payments
from its own resources to intermediaries for providing certain services for
shareholders and for the maintenance of shareholder accounts. This in no way
affects the advisory fee paid by the Fund. Contact the Investment Adviser for
more information.

EXPENSE WAIVERS

The Investment Adviser has agreed to waive its fees and absorb other operating
expenses of the Fund so that total operating expenses (excluding taxes,
interest, brokerage and extraordinary expenses of the Class I, II, III and IV)
do not exceed ___%, respectively, as an average of the Fund's daily net assets
through March 31, 2006.

The Fund reduces expenses by offsets to custodial and other fees based upon the
amount of securities lent to third parties and cash maintained with its
custodian. These offset arrangements will have no effect on the amount of fees
that the Investment Adviser must waive or expenses that it must otherwise
reimburse under the Expense Limitation Agreement.

MULTI CLASS STRUCTURE

The Fund offers multiple classes of shares. The sole economic difference among
the various classes of shares is the level of shareholder service and
administrative service fees that the classes bear for the client and shareholder
service, administrative services, reporting and other support, reflecting the
fact that, as the size of the client relationship increases, the cost to service
that client decreases as a percentage of the assets in that account. Thus, the
shareholder service and administrative service fees are lower for classes where
the eligibility criteria require greater total assets under the Investment
Adviser's management.

PORTFOLIO TRADES

The Investment Adviser is responsible for the Fund's portfolio transactions. In
placing portfolio trades, the Investment Adviser may use brokerage firms that
provide research services to the Fund but only when the Investment Adviser
believes no other firm offers a better combination of quality execution (e.g.,
timeliness and completeness) and favorable price.

The Investment Adviser may allocate brokerage transactions to brokers who have
entered into expense offset arrangements with the Investment Adviser under which
a broker allocates a portion of the commissions paid by a Fund toward the
reduction of the Fund's expenses.

PORTFOLIO TURNOVER

To the extent that the Investment Adviser actively trades the Fund's portfolio
securities in an attempt to achieve the Fund's investment goal, such trading may
cause the Fund to have an increased portfolio turnover rate of 150% or more,
which has the potential to generate shorter-term gains (losses) for its
shareholders, which are taxed as ordinary income with rates that are higher than
longer-term gains (losses). Actively trading portfolio securities may have an
adverse impact on the Fund's performance.

PORTFOLIO HOLDINGS

A description of the Fund's policies and procedures with respect to the
disclosure of the Funds' portfolio securities is available in the Fund's
SAI.

                                       10
<Page>

PORTFOLIO MANAGEMENT

The Investment Adviser applies a team approach to portfolio management and
investment research, with ultimate buy and sell decision-making authority vested
in a lead portfolio manager accountable for each investment team's results. All
portfolio management activities are overseen by Nicholas-Applegate's Chief
Investment Officer, Horacio A. Valeiras, CFA. Day-to-day management of the
Fund's portfolio is performed by Vincent Willyard, CFA Lead Portfolio Manager.
Mr. Willyard is primarily assisted by Joseph Devine and Barry Kendall.
Information regarding the portfolio management team is listed below.

The portfolio management team is assisted by the entirety of
Nicholas-Applegate's Investments Team. Team members provide research reports and
make securities recommendations with respect to the Fund's portfolio, but do not
have primary responsibility for day-to-day portfolio management.

PRINCIPAL STRATEGIES, RISKS AND OTHER INFORMATION

MORE ABOUT THE FUND

The Fund's goal and principal investment strategies, and the main risks of
investing in the Fund, are summarized at the beginning of this prospectus. More
information on investment strategies, investments and risks appears in this
section. Except as noted below, the Fund's investment policy may be changed
without shareholder approval. The Fund will provide shareholders with at least
60 days prior notice of a change in the Fund's investment policy. There can, of
course, be no assurance that the Fund will achieve its investment goal.

The Fund may also use strategies and invest in securities that are not described
in the Statement of Additional Information. Of course, the Investment Adviser
may decide, as a matter of investment strategy, not to use the investments and
investment techniques described below and in the Statement of Additional
Information at any particular time.

MARKET DISRUPTION

As a result of the terrorist attack on the World Trade Center and Pentagon on
September 11, 2001, some of the U.S. securities markets were closed for a
four-day period. These terrorist attacks have led to unusual short-term market
volatility and may have long-term effects on the U.S. and world economies and
markets. A similar disruption of the financial markets could impact the market
risk, liquidity risk and interest rate risk relating to your investment.

INTERNATIONAL INVESTMENT RISKS AND CONSIDERATIONS

CURRENCY FLUCTUATION. When the Fund invests in instruments issued by non-U.S.
companies, the principal, income and sales proceeds must be paid to the Fund in
local non-U.S. currencies. A reduction in the value of local currencies relative
to the U.S. dollar could mean a corresponding reduction in the value of the
Fund's investments. Also, the Fund may incur costs when converting from one
currency to another.

SOCIAL, POLITICAL AND ECONOMIC FACTORS. The economies of many of the countries
where the Funds may invest may be subject to a substantially greater degree of
social, political and economic instability than the United States. This
instability might impair the financial conditions of issuers or disrupt the
financial markets in which the Funds invest.

The economies of non-U.S. countries may differ significantly from the economy of
the United States as to, for example, the rate of growth of gross domestic
product or rate of inflation. Governments of many non-U.S. countries continue to
exercise substantial control over private enterprise and own or control many
companies. Government actions such as imposition of exchange control regulation,
withholding taxes, limitations on the removal of funds or other assets,
expropriation of assets and confiscatory taxation could have a significant
impact on economic conditions in certain countries which could affect the value
of the securities in the Fund.

INFLATION. Certain countries, especially many emerging market countries, have
experienced substantial, and in some periods extremely high and volatile, rates
of inflation. Rapid fluctuations in inflation rates and wage and price controls
may continue to have unpredictable effects on the economies, companies and
securities markets of these countries.

DIFFERENCE IN SECURITIES MARKETS. The securities markets in non-U.S. countries
have substantially less trading volume than the markets in the United States and
debt and equity securities of many companies listed on such markets may be less
liquid and more volatile than comparable securities in the United States. Some
of the stock exchanges in non-U.S. countries, to the extent that established
markets exist, are in the earlier states of their development. The limited
liquidity of certain securities markets may affect the ability of the Fund to
buy and sell securities at the desired price and time.

Trading practices in certain non-U.S. countries are also significantly different
from those in the United States. Although brokerage commissions are generally
higher than those in the U.S., the Investment Adviser will seek to achieve the
most favorable net results. In addition, securities settlements and clearance
procedures may be less developed and less reliable than those in the United
States. Delays in settlement could result in temporary periods in which the
assets of the Fund are not fully invested, or could result in the Fund being
unable to sell a security in a falling market.

CUSTODIAL AND REGISTRATION PROCEDURES. Systems for the registration and transfer
of securities in non-U.S. markets can be less developed than similar systems in
the United States. There may be no standardized process for registration of
securities or a central registration system to track share ownership. The
process for transferring shares may be cumbersome, costly, time-consuming and
uncertain.

GOVERNMENT SUPERVISION OF SECURITIES MARKETS. Disclosure and regulatory
standards in many non-U.S. countries are, in many respects, less stringent than
those in the United States. There may be less government supervision and
regulation of securities exchanges, listed companies, investors, and brokers in
non-U.S. countries than in the United States, and enforcement of existing
regulations may be extremely limited.

                                       12
<Page>

FINANCIAL INFORMATION AND REPORTING STANDARDS. Issuers in non-U.S. countries are
generally subject to accounting, auditing, and financial standards and
requirements that differ, in some cases materially, from those in the United
States. In particular, the assets and profits appearing in financial statements
may not reflect their financial position or results in the way they would be
reflected had the statements been prepared in accordance with U.S. generally
accepted accounting principles. Consequently, financial data may not reflect the
true condition of those issuers and securities markets.

EQUITY-LINKED SECURITIES AND RISKS

The Fund may purchase Equity-Linked Securities, also known as participation
notes, equity swaps, and zero strike calls and warrants. Equity-linked
securities are primarily used by a Fund as an alternative means to more
efficiently and effectively access the securities market of what is generally an
emerging country. The Fund deposits an amount of cash with its custodian (or
broker, if legally permitted) in an amount near or equal to the selling price of
the underlying security in exchange for an equity linked security. Upon sale,
the Fund receives cash from the broker or custodian equal to the value of the
underlying security. Aside from market risk there is of the underlying security,
there is the risk of default by the other party to the transaction. In the event
of insolvency of the other party, the Fund might be unable to obtain its
expected benefit. In addition, while the Fund will seek to enter into such
transactions only with parties which are capable of entering into closing
transactions with the Fund, there can be no assurance that the Fund will be able
to close out such a transaction with the other party or obtain an offsetting
position with any other party, at any time prior to the end of the term of the
underlying agreement. This may impair the Fund's ability to enter into other
transactions at a time when doing so might be advantageous.

TEMPORARY INVESTMENTS AND RISKS

The Fund may, from time to time, invest all of its assets in short-term
instruments when the Investment Adviser determines that adverse market,
economic, political or other conditions call for a temporary defensive posture.
Such a defensive position may result in the Fund failing to achieve its
investment objective.

LENDING OF PORTFOLIO SECURITIES AND RISK

In order to generate expense offset credits, the Fund may lend portfolio
securities, on a short-term or a long-term basis, up to 30% of its total assets
to broker/dealers, banks, or other institutional borrowers of securities. The
Fund will only enter into loan arrangements with broker/dealers, banks, or other
institutions which the Investment Adviser has determined are creditworthy and
under guidelines established by the Board of Trustees and will receive
collateral in the form of cash or U.S. government securities equal to least 102%
of the value of the securities loaned on U.S. securities.

There is the risk that when lending portfolio securities, the securities may not
be available to the Fund on a timely basis and the 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.

NON PRINCIPAL STRATEGIES

HEDGING TRANSACTION AND RISKS

The Fund may trade in derivative contracts to hedge portfolio holdings or an
underweighting relative to the Fund's index. Hedging activities are intended to
reduce various kinds of risks. For example, in order to protect against certain
events that might cause the value of its portfolio securities to decline, the
Fund can buy or sell a derivative contract (or a combination of derivative
contracts) intended to rise in value under the same circumstances. Hedging
activities will not eliminate risk, even if they work as they are intended to.
In addition, these strategies are not always successful, and could result in
increased expenses and losses to the Fund. The Fund may trade in the following
types of derivative contracts.

FUTURES CONTRACTS provide for the future sale by one party and purchase by
another party of a specified amount of an underlying asset at a price, date, and
time specified when the contract is made. Futures contracts traded OTC are
frequently referred to as forward contracts. Entering into a contract to buy is
commonly referred to as buying or purchasing a contract or holding a long
position. Entering into a contract to sell is commonly referred to as selling a
contract or holding a short position. Futures are considered to be commodity
contracts. The Fund can buy or sell futures contracts on portfolio securities or
indexes and engage in non-U.S. currency forward contracts.

OPTIONS are rights to buy or sell an underlying asset for a specified price (the
exercise price) during, or at the end of, a specified period of time. A call
option gives the holder (buyer) the right to purchase the underlying asset from
the seller (writer) of the option. A put option gives the holder the right to
sell the underlying asset to the writer of the option. The writer of the

                                       13
<Page>

option receives a payment, or "premium," from the buyer, which the writer keeps
regardless of whether the buyer uses (or exercises) the option.

When the Fund uses financial futures and options on financial futures as hedging
devices, much depends on the ability of the portfolio manager to predict market
conditions based upon certain economic analysis and factors. There is a risk
that the prices of the securities subject to the futures contracts may not
correlate perfectly with the prices of the securities in the Fund's portfolio.
This may cause the futures contract and any related options to react differently
than the portfolio securities to market changes. In addition, the portfolio
managers could be incorrect in their expectations about the direction or extent
of market factors such as interest rate movements. In these events, the Fund may
lose money on the futures contracts or options.

It is not certain that a secondary market for positions in futures contracts or
for options will exist at all times. Although the Investment Adviser will
consider liquidity before entering into options transactions, there is no
assurance that a liquid secondary market on an exchange or otherwise will exist
for any particular futures contract or option at any particular time. The Fund's
ability to establish and close out futures and options positions depends on this
secondary market.

                      AGREEMENT AND PLAN OF REORGANIZATION

     This Agreement and Plan of Reorganization (the "Plan" or "Agreement") is
made as of this ___ day ____________________, 2005, by and between
Nicholas-Applegate Institutional Funds (the "Institutional Funds") on behalf of
the Nicholas-Applegate International All-Cap Growth Fund (the "Acquiring Fund")
and the Professionally Managed Portfolios, on behalf of the Nicholas-Applegate
International All-Cap Growth Fund (the "Acquired Fund").

BACKGROUND

     WHEREAS, the Acquired Fund and the Acquiring Fund are series of registered

          pending against it and, to the best of its knowledge; none is
          threatened against it or any of its properties or assets, which, if
          adversely determined, would materially and adversely affect its
          financial condition or the conduct of its business. It knows of no
          facts which might form the basis for the institution of such

          accounting principles, consistently applied, and such statements
          (copies of which have been furnished to the Acquiring Fund) fairly
          reflect its financial condition as of such date.

               (f)  Absence of Certain Changes or Events. Since March 30, 2005
          there has not been any material adverse change in its financial
          condition, assets, liabilities or business other than changes
          occurring in the ordinary course of business, or any incurrence of
          indebtedness maturing more than one year from the date of such

          are, and on the Closing Date will be, duly and validly issued and

              PRO FORMA COMBINING NOTES TO FINANCIAL STATEMENTS
               OF DUNCAN-HURST INTERNATIONAL GROWTH FUND INTO
            NICHOLAS-APPLEGATE INTERNATIONAL ALL-CAP GROWTH FUND
                              March 31, 2005
                                (UNAUDITED)

NOTE 1 - BASIS OF PRO FORMA PRESENTATION

     The pro forma financial statements and the accompanying pro forma
schedule of investments give effect to the proposed Plan of Reorganization
between Nicholas-Applegate International All-Cap Growth Fund (a series of
Professionally Managed Portfolios) (the "Acquired Fund") and
Nicholas-Applegate All-Cap Growth Fund (a newly organized series of
Nicholas-Applegate Institutional Funds) (the "Acquiring Fund") (collectively,
the "Reorganization") and the consummation of transactions contemplated
therein to be accounted for as a tax-free reorganization of investment
companies. The Reorganization would be accomplished by an exchange of shares
of the Acquiring Fund for the net assets of the Acquired Fund the
distribution of Acquiring Fund shares to the Acquired Fund shareholders. If
the Reorganization were to have taken place at March 31, 2005, Acquired Fund
- - Class I shareholders would have received 3,729,694 shares of Acquiring Fund
- - Class I shares.

     The preparation of pro forma combined financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities at the date of the pro forma
combined financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

NOTE 2 - PRO FORMA ADJUSTMENTS

     (a) Under the terms of the interim investment advisory agreement of
Acquired Fund (the "Agreement"), the advisory fees based on pro forma
combined assets for the year ended March 31, 2005 were $281,550. The advisory
fees were adjusted to reflect the advisory fee rates for the Acquiring Fund.
Upon the closing date of the Reorganization, the advisory fee payable by

PART C. OTHER INFORMATION

Item 15. INDEMNIFICATION

     Registrant's trustees, officers, employees and agents are indemnified
against liabilities incurred by them in connection with the defense or
disposition of any action or proceeding in which they may be involved or with
which they may be threatened, while in office or thereafter, by reason of being
or having been in such office, except with respect to matters as to which it has
been determined that they acted with willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of their
office ("Disabling Conduct").

     Section 3 of Registrant's Administrative Services Agreement, filed as
Exhibit (h)(2) to Registrant's Form N-1A Registration Statement on May 6, 1999
and incorporated herein by reference, provides for the indemnification of
Registrant's Administrator against all liabilities incurred by it in performing
its obligations under the Agreement, except with respect to matters involving
its Disabling Conduct. Section 9 of Registrant's Distribution Agreement, filed
as Exhibit (e)(1) to Registrant's Form N-1A Registration Statement on May 6,
1999 and incorporated herein by reference, provides for the indemnification of
Registrant's Distributor against all liabilities incurred by it in performing
its obligations under the Agreement, except with respect to matters involving
its Disabling Conduct. Section 8 of the Shareholder Service Agreement, filed as
Exhibit (e)(3) to Registrant's Form N-1A Registration Statement on May 6, 1999
and incorporated herein by reference, provides for the indemnification of
Registrant's Distributor against all liabilities incurred by it in performing
its obligations under the Agreement, except with respect to matters involving
its Disabling Conduct.

     Registrant has obtained from a major insurance carrier a trustees' and
officers' liability policy covering certain types of errors and omissions.
Insofar as indemnification for liabilities arising under the Securities Act of
1933, as amended, may be permitted to trustees, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a trustee, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such trustee, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933, as amended, and will be governed by the final adjudication of such
issue.

     Article V. of Nicholas-Applegate Institutional Fund's Amended and Restated
Declaration of Trust provides as follows:

          5.2 INDEMNIFICATION OF TRUSTEES, OFFICERS, EMPLOYEES, AGENTS. The
     Trust shall indemnify each of its Trustees, officers, employees, and agents
     (including Persons who serve at its request as directors, officers or
     trustees of another organization in which it has any interest, as a
     shareholder, creditor or otherwise) against all liabilities and expenses
     (including amounts paid in satisfaction of judgments, in compromise, as
     fines and penalties, and as counsel fees) reasonably incurred by him or her
     in connection with the defense or disposition of any action, suit or other
     proceeding, whether civil or

     criminal, in which he or she may be involved or with which he or she may be
     threatened, while in office or thereafter, by reason of his or her being or
     having been such a Trustee, officer, employee or agent, except with respect
     to any matter as to which he or she shall have been adjudicated to have
     acted in bad faith, willful misfeasance, gross negligence or reckless
     disregard of his or her duties; provided; however, that as to any matter
     disposed of by a compromise payment by such Person, pursuant to a consent
     decree or otherwise, no indemnification either for said payment or for any
     other expenses shall be provided unless there has been a determination that
     such Person did not engage in willful misfeasance, bad faith, gross
     negligence or reckless disregard of the duties involved in the conduct of
     his or her office by the court or other body approving the settlement or
     other disposition or by a reasonable determination, based upon review of
     readily available facts (as opposed to a full trial-type inquiry), that he
     or she did not engage in such conduct by written opinion from independent
     legal counsel approved by the Trustees. The rights accruing to any Person
     under these provisions shall not exclude any other right to which he or she
     may be lawfully entitled; provided that no Person may satisfy any right of
     indemnity or reimbursement granted herein or in Section 5.1 or to which he
     or she may be otherwise entitled except out of the Trust Property. The
     Trustees may make advance payments in connection with indemnification under
     this Section 5.2, provided that the indemnified Person shall have given a
     written undertaking to reimburse the Trust in the event it is subsequently
     determined that he or she is not entitled to such indemnification.
