Dear Shareholder:
 
    A special meeting of shareholders of Nicholas-Applegate Mutual Funds (the
"Trust") will be held to determine important organizational issues affecting
your portfolio. The meeting will begin at 9:00 a.m. local time on February 27,
1998, at the offices of the Trust, 600 West Broadway, 30th Floor, San Diego,
California 92101.
 
    At the meeting shareholders of the Trust will be asked to approve a
reorganization in which the Trust will move from a complex "master-feeder"
structure to a simpler and more economical "multi-class" structure. The
reorganization is administrative in nature and, while it is very important for
the efficient and cost-effective long-term administration of the Trust, it will
not affect the objectives, policies or risks of your investment. You may
benefit, however, from the reduced cost of administering the Trust.
 
    Shareholders will also be asked to elect Trustees to take office when the
reorganization is concluded and to ratify the selection of Ernst & Young L.L.P.
as independent public accountants of the Trust.
 
    The proposals have been carefully reviewed by your Board of Trustees, which
recommends that you approve them. Please read the enclosed materials carefully,
and sign, date and mail the enclosed proxy card(s) promptly in the enclosed
return envelope. Your vote is important for the proper administration of the
Trust.
 
   
    Thank you for your attention to this matter. If you have any questions on
voting of proxies or the proposals to be considered at the meeting, please call
us toll free at 1-800-551-8045.

                            ------------------------
 
   
    This Combined Proxy Statement and Prospectus, which includes a Notice of
Special Meeting of Shareholders, a Proxy Statement and a form of Proxy, is being
furnished in connection with the special meeting of shareholders of
Nicholas-Applegate Mutual Funds (the "Trust") to be held on February 27, 1998,
and any adjournment thereof (the "Meeting"). It is being furnished to the
shareholders of all portfolios of the Trust other than the Government Income
portfolios (the "Portfolios"). Shareholders of the Government Income portfolios
are being asked to approve their reorganization into another portfolio, and are
receiving a separate Combined Proxy Statement and Prospectus in connection with

    The various A, B, C, Qualified and Institutional Portfolios of the Trust and
the Money Market Portfolio of the Trust currently invest all of their assets in
corresponding "master funds" of Nicholas-Applegate Investment Trust. At the
Meeting the shareholders of these Portfolios will be asked to approve a
reorganization in which the Trust will move from this "master-feeder" structure
to a "multi-class" structure. As a result of the reorganization, each Portfolio
will invest directly in portfolio securities rather than through the master
funds, and each shareholder of an A, B, C, Qualified or Institutional Portfolio
will receive Class A, B, C, Q or I shares of a corresponding multi-class series
of the Trust having the same aggregate net asset value as the shares of the
Portfolio held by such shareholder at the time of closing of the reorganization.
The investment objectives, policies and risks of each multi-class series will be
identical to the investment objectives, policies and risks of the corresponding
Portfolios.
    
 
    The shareholders of the Trust also will be asked to elect Trustees of the
Trust and to ratify the selection of Ernst & Young L.L.P. as independent
accountants.
 
   
    The Trust is an open-end, management investment company comprised of a
number of diversified portfolios. This Combined Proxy Statement and Prospectus
sets forth concisely the information that a shareholder of the Portfolios should
know before voting on the proposed reorganization and related actions. It should
be read and retained for future reference.
    
 
   
    The most recent Prospectuses and Statements of Additional Information
relating to each A, B, C, Qualified and Institutional Portfolio of the Trust are
on file with the Securities and Exchange Commission and are incorporated by
reference herein. They are available without charge by writing or calling the
Trust at its address and telephone number above. The Preliminary Prospectus
relating to the corresponding Class A, B, C, Q or I shares of the Trust to be
distributed to the shareholders pursuant to the reorganization accompanies this
document. The Preliminary Statements of Additional Information relating to the
Class A, B, C, Q and I shares of the Trust are also incorporated herein by
reference and are available without charge by writing or calling the Trust at
its address and telephone number above.

    THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON
THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY
IS A CRIMINAL OFFENSE.

SOLICITATION OF PROXIES
 
   
    This Combined Proxy Statement and Prospectus (the "Proxy Statement") is
being furnished to the shareholders of Nicholas-Applegate Mutual Funds (the
"Trust") in connection with the solicitation of proxies by the Board of Trustees
of the Trust for use at a special meeting of shareholders to be held on February
27, 1998, and any adjournment thereof (the "Meeting"). It is being furnished to
the shareholders of all portfolios of the Trust other than the Government Income
portfolios (the "Portfolios"). Shareholder of the Government Income portfolios
are being asked to approve their reorganization into another portfolio, and are
receiving a separate Combined Proxy Statement and Prospectus in connection with
the Meeting.
    
 
   
    The Meeting will be held at the offices of the Trust, 600 West Broadway,
30th Floor, San Diego, California 92101, for the purposes set forth in the
Notice of Special Meeting of Shareholders and more fully described below. This
Proxy Statement and the enclosed form of proxy (the "Proxy") were first mailed
to shareholders of the Portfolios entitled to vote at the Meeting on or about
January 12, 1998.
    
 
PURPOSE OF MEETING
 
   
    The Meeting has been called for the purpose of considering a reorganization
in which the Trust will move from a "master-feeder" structure to a "multi-class"
structure (the "Reorganization"). Currently, the A, B, C, Qualified and
Institutional Portfolios of the Trust and the Money Market Portfolio of the
Trust, known as "feeder funds," invest all of their assets in shares of
corresponding funds, known as "master funds," of Nicholas-Applegate Investment
Trust (the "Master Trust"). As a result of the Reorganization the Trust will
manage its assets directly rather than through the Master Trust, and each
shareholder of an A, B, C, Qualified or Institutional Portfolio will receive
Class A, B, C, Q or I shares of a corresponding portfolio of the Trust. The
Money Market Portfolio will not have multiple classes, and the series of the
Trust created after August 1, 1997 (the Global Blue Chip Bond Fund, Emerging
Markets Bond Fund, Pacific Rim Fund, Greater China Fund and Latin America Fund)
are not part of the master-feeder structure and will not be affected by the
Reorganization. The Board of Trustees and management of the Trust believe that
the Reorganization will result in substantial economies for the Trust. The
Reorganization will not affect the net asset value of the shares held by any
shareholder; the investment objectives, policies or risks of any Portfolio; or
the basic arrangements for management of the Trust. Legal counsel has advised
the Trust that under the Internal Revenue Code the Reorganization will not
result in taxable income to the Portfolios or their shareholders. Except for the
minor differences described below, shareholders will notice little difference in
the investment represented by their Class A, B, C, Q or I shares or Money Market
shares as compared to the Portfolio shares they now hold.
    
 
   
    To accomplish the Reorganization, the shareholders of the Portfolios will be
asked to vote on three matters. First, the shareholders of the Institutional
Portfolios will be asked to approve an amendment to the Declaration of Trust
authorizing the Board of Trustees to create classes of shares of the
Institutional Portfolios (Proposal 1). As described more fully below, the
Institutional Portfolios will be renamed as the "Funds" and the existing
Institutional Portfolio shares will be designated as "Class I" shares of the
Funds. Second, the shareholders of each of the Institutional Portfolios and the
Money Market Portfolio will be asked to authorize the Board of Trustees to
eliminate such Portfolio's current policy of investing all of its assets in the
corresponding portfolio of the Master Trust (Proposal 2). Third, the
shareholders of the A, B, C, and Qualified Portfolios will be asked to approve a
Reorganization Agreement, pursuant to which (i) the A, B, C and Qualified
Portfolios will receive their pro rata portions of the assets of the
corresponding master funds upon the dissolution of the Master Trust; (ii) the A,
B, C and Qualified Portfolios will transfer their assets to the corresponding
Fund in exchange for Class A, B, C and Q shares of such Fund; (iii) the
shareholders of the A, B, C and Qualified Portfolios will receive shares of
    
 
                                       1
<PAGE>
   
corresponding Classes of the Funds in exchange for their current shares, and
(iv) the Portfolios will be terminated (Proposal 3).
    
 
   
    All shareholders of the Trust will also be asked to act on two other
matters--the election of Trustees to take office when the Reorganization is
concluded (Proposal 4) and ratification of the selection of Ernst & Young L.L.P.
as independent public accountants to the Trust (Proposal 5).
    
 
   
    The following chart summarizes the Proposals on which the shareholders of
the Portfolios will be asked to vote:

    Nicholas-Applegate Capital Management (the "Investment Adviser") will bear
50% of the cost of solicitation of proxies, including the cost of printing,
preparing, assembling and mailing the Notice of Meeting, Proxy Statement and
form of Proxy, and the balance will be paid by the Trust (allocated among the
various series of the Trust in proportion to their net assets). In addition to
solicitations by mail, proxies may be solicited by officers and regular
employees of the Trust and the Investment Adviser by personal interview, by
telephone or by facsimile. Tritech will also be retained to provide professional
proxy solicitation services. The cost of solicitation, including specified
expenses, is not expected to exceed $275,000.
    
 
                               SHARES AND VOTING
 
    The presence in person or by proxy of more than one-third of the outstanding
shares of beneficial interest of the Trust entitled to vote at the Meeting will
constitute a quorum. If a quorum is not present at the Meeting, sufficient votes
in favor of the Proposals set forth in the Notice of Meeting are not received by
the time scheduled for the Meeting, or the holders of shares present in person
or by proxy determine to adjourn the Meeting for any other reason, the
shareholders present in person or by proxy may adjourn the Meeting from time to
time, without notice other than announcement at the Meeting. Any such
adjournment will require the affirmative vote of shareholders holding a majority
of the shares present in person or by proxy at the Meeting. The persons named in
the Proxy will vote in favor of adjournment those shares which they represent if
adjournment is necessary to obtain a quorum or to obtain a favorable vote on any
Proposal. Business may be conducted once a quorum is present and may continue
until adjournment of the Meeting notwithstanding the withdrawal or temporary
absence of sufficient shares to reduce the number present to less than a quorum.
 
    Each shareholder is entitled to one vote for each full share and a
fractional vote for each fractional share outstanding on the books of the Trust
in the name of the shareholder or his or her nominee on the Record Date. The
Record Date and time for determining those entitled to notice of and to vote at
the Meeting has been fixed at the close of business on December 19, 1997.
 
   
    At the Record Date, the Trust had 60 series of shares and 236,442,334.025
total shares outstanding, and each series had the number of outstanding shares
indicated in Appendix A. Appendix A also indicates the persons who owned of
record more than 5% of the outstanding shares of each series at the Record
    
 
                                       2
<PAGE>
Date. The Trust has no information regarding the beneficial owners of such
shares. Except as indicated in Appendix A, the officers and Trustees of the
Trust as a group beneficially owned less than 1% of the outstanding shares of
each series at the Record Date.
 
   
    All shares represented by each properly signed Proxy received prior to the
Meeting will be voted at the Meeting. If a shareholder specifies how the Proxy
is to be voted on a Proposal to be considered at the Meeting, it will be voted
as specified. If no direction is made on the Proxy, the Proxy will be voted FOR
the Proposals described in this Proxy Statement. Shareholders voting to ABSTAIN
on a Proposal will be treated as present for purposes of achieving a quorum and
in determining the votes cast on the Proposal. A properly signed Proxy on which
a broker has indicated that it has no authority to vote on a Proposal on behalf
of the beneficial owner (a "broker non-vote") will be treated as present for
purposes of achieving a quorum but will not be counted in determining the votes
cast on the Proposal.
    
 
   
    A Proxy may be revoked by a shareholder at any time prior to its use by
written notice to the Trust, by submission of a later dated proxy or by voting
in person at the Meeting. If any other matters come before the Meeting, Proxies
will be voted by the persons named in the Proxy in accordance with their best
judgement.
    
 
   
    Shareholders of each Institutional Portfolio will vote separately with
respect to Proposal 1. Shareholders of the Money Market Portfolio and each
Institutional Portfolio will vote separately with respect to Proposal 2.
Shareholders of each A, B, C, and Qualified Portfolio will vote separately with
respect to Proposal 3. All of the shareholders of the Trust will vote in the
aggregate with respect to Proposals 4 and 5.
    
 
                   BACKGROUND OF THE PROPOSED REORGANIZATION
 
   
    Unlike other mutual funds that acquire their securities directly, the
Portfolios of the Trust created prior to August 1, 1997 invest their assets in
funds of the Master Trust. This two-tier structure is known as a "master-feeder"
structure and it permits one or more feeder funds that have the same investment
objectives but different operating characteristics (such as sales charges,
expenses and investment minimums) to invest in the same master fund.
    
 
   
    When the Board of Trustees of the Trust established the master-feeder
structure in 1993, it believed this form of organization would achieve certain
efficiencies of operation and economies of scale. However, since the
establishment of the master-feeder structure, the number of portfolios organized
by the Trust using that structure has increased significantly, to 57.
Furthermore, regulatory developments have occurred enabling mutual fund
complexes to more easily achieve, through the use of multiple classes of shares,
the benefits at one time expected of the master-feeder approach without the
operating costs and technical complexities of a two-tiered structure.
    
 
   
    The purpose of the Reorganization is to eliminate the cost and complexity of
a master-feeder structure that has not yielded and is no longer expected to
yield long-term efficiencies of operation and economies of scale. Management of
the Trust expects the Reorganization to save the Trust approximately $1,000,000
per year in fees currently paid to the company which provides day-to-day
accounting services to the Trust. In addition, the number of tax returns
currently filed annually by the Trust and the Master Trust would be reduced from
129 to 38 and separate audits for the master funds would no longer be necessary,
with an annual savings of approximately $180,000. Over time the Trust would also
benefit from the fewer number of required SEC filings and other legal and
administrative cost savings.
    
 
   
    As Investment Adviser to the Master Trust, Nicholas-Applegate Capital
Management has to date voluntarily agreed to defer its management fees and to
absorb other operating expenses payable by the Trust and the Master Trust, to
the extent necessary to ensure that the expenses for each Portfolio (other than
interest, taxes, brokerage commissions and other portfolio transaction expenses,
capital expenditures and extraordinary expenses) do not exceed certain levels.
Accordingly, the shareholders of the Trust have in the past not borne the full
cost of the master-feeder structure. However, the Board of Trustees believes
    
 
                                       3
<PAGE>
that the Reorganization will benefit the shareholders of the Trust. Any expenses
in excess of the current expense caps may be borne by the shareholders in the
future, as in subsequent years each Portfolio will reimburse the Investment
Adviser when operating expenses (before recoupment) for the Portfolio are less
than the expense cap. Furthermore, although the Investment Adviser has
maintained these expense caps since the Portfolios commenced operation and has
agreed to maintain them through March 31, 1999, there can be no assurance it
will do so indefinitely in the future.
 
    In addition, the proposed Reorganization will permit the Trust to provide
for the automatic conversion of its current Portfolio B shares to Portfolio A
shares seven years after purchase. Although Portfolio B shares may currently be
exchanged voluntarily for the corresponding Portfolio A shares seven years after
purchase, the exchange is treated as a redemption and purchase for tax purposes.
In the proposed multi-class structure, the Trust will be able to provide for
automatic conversion without adverse federal income tax consequences. Such an
exchange is beneficial for long-term shareholders, as Portfolio A shares have
lower annual distribution-related fees than Portfolio B shares.
 
   
    The proposed Amendment to the Trust's Declaration of Trust (Proposal 1), the
proposed amendments to the policies of the Money Market Portfolio and
Institutional Portfolios (Proposal 2), the proposed Reorganization (Proposal 3),
and the proposed election of Trustees (Proposal 4) are related parts of a plan
to achieve future operating economies. Neither Proposal 1, Proposal 2 nor
Proposal 3 will be adopted unless all are approved by the shareholders. Proposal
4 will not be adopted unless Proposals 1, 2 and 3 are approved by the
shareholders.
    
 
                 PROPOSAL 1.  AMENDMENT OF DECLARATION OF TRUST
 
    At the Meeting, shareholders of the Institutional Portfolios will be asked
to approve an amendment to the Trust's Declaration of Trust to permit the Board
of Trustees to create multiple classes of the Institutional Portfolios.
 
   
    Section 6.1(b) of the Declaration of Trust currently permits the Board of
Trustees to create multiple classes of a Portfolio only if the Portfolio was
organized after August 1, 1997. The proposed amendment would expand this to
include all of the Institutional Portfolios. The language proposed to be added
to the first sentence of Section 6.1(b) is indicated below by underlining:
    
 
    The Trustees may, without Holder approval, divide Interests of any
    series created after the Effective Date [August 1, 1997], or any
    Institutional Portfolio series created prior to the Effective Date, into
    two or more classes, Interests of each such class having such
    preferences and special or relative rights and privileges (including
    conversion rights, if any) as the Trustees may determine.
 
   
    As described above, upon approval of the proposed amendment, and provided
that Proposal 2 is approved, the Board of Trustees will rename each
Institutional Portfolio of the Trust as a "Fund," will classify the current
shareholders of the Institutional Portfolio as Class I shareholders of the Fund,
and will create Class A, B, C, and Q shares of the Fund to permit the
Reorganization to be implemented.
    
 
   
    Approval of the proposed amendment will not have any impact on the
shareholders of the Portfolios other than to permit the tax-free conversion of
Portfolio B shares for Portfolio A shares seven years after their purchase. Each
share of each Portfolio currently is entitled to one vote on each matter
presented to the shareholders of the Portfolio--for matters that affect the
rights and privileges of a Portfolio differently from the rights and privileges
of other series of the Trust, the shareholders of the Portfolio vote separately;
for matters that affect the master fund in which the Portfolio invests (such as
a change in fundamental investment restrictions), the shareholders of the
Portfolio vote together with the shareholders of all other portfolios investing
in the corresponding master fund; and for matters that affect the Trust
generally (such as the election of Trustees), all shareholders vote together.
Similarly each share of each Class of a Fund will be entitled to one vote on
each matter presented to the shareholders of the Class--for matters that affect
the rights and privileges of a Class differently from the rights and privileges
of other Classes of the Fund,
    
 
                                       4
<PAGE>
   
the shareholders of the affected Class will vote separately; for matters that
affect a Fund, the shareholders of each Class will vote together with the
shareholders of all other Classes of the Fund; and for matters that affect the
Trust generally, the shareholders of all Classes of all Funds will vote
together. As is the case for shares of the Portfolios, shares of the Classes
will have no preemptive or subscription rights and no other conversion rights,
and will be freely transferrable.
    
 
VOTE REQUIRED
 
   
    Approval of the proposed amendment requires the affirmative votes of
shareholders holding more than 50% of the outstanding shares of each
Institutional Portfolio voting separately. Approval of this Proposal is
contingent upon approval of Proposals 2 and 3. If shareholders of all the
Institutional Portfolios do not approve this Proposal or it is not implemented
for any other reason, then the Trust will continue its current operation under a
master-feeder structure until the Board of Trustees determines what further
action, if any, to recommend to the shareholders.
    
 
   
                  PROPOSAL 2.  AMENDMENT OF INVESTMENT POLICY
    
 
   
    At the meeting, shareholders of the Money Market Portfolio and the
Institutional Portfolios will be asked to authorize the Board of Trustees to
eliminate each such Portfolio's current policy of investing all of its assets in
the corresponding master fund of the Master Trust.
    
 
   
    The policies of the Money Market Portfolio and the Institutional Portfolios
currently require them to operate under the "master-feeder" structure, and the
Trust has undertaken to obtain approval of their shareholders before eliminating
the master-feeder structure. As discussed in Proposal 1 and further described in
Proposal 3, upon completion of the Reorganization the Trust will move to a
"multi-class" structure, and all of the shareholders of the A, B, C and
Qualified Portfolios will become shareholders of corresponding Classes of the
Institutional Portfolios (which will be renamed as the "Funds" and will invest
their assets directly rather than through the Master Trust).
    
 
   
    Approval of this proposed change in policy will have the impacts discussed
in Proposal 3.
    
 
   
VOTE REQUIRED
    
 
   
    Approval of the proposed change in policy requires the affirmative votes of
shareholders holding more than 50% of the outstanding shares of the Money Market
Portfolio and each Institutional Portfolio voting seperately. Approval of this
Proposal is contingent upon approval of Proposals 1 and 3. If shareholders of
the Money Market Portfolio and all the Institutional Portfolios do not approve
this Proposal or it is not implemented for any other reason, then the Trust will
continue its current operation under a master-feeder structure until the Board
of Trustees determines what further action, if any, to recommend to the
shareholders.
    
 
   
              PROPOSAL 3.  APPROVAL OF THE PROPOSED REORGANIZATION
    
 
   
    At the Meeting, shareholders of the A, B, C, and Qualified Portfolios will
be asked to approve the proposed Reorganization.
    
 
DESCRIPTION OF THE PROPOSED REORGANIZATION
 
THE REORGANIZATION AGREEMENT
 
    The terms and conditions under which the Reorganization will be completed
are set forth in the Agreement and Plan of Reorganization (the "Reorganization
Agreement") attached as Appendix B. The following is a summary of the
Reorganization Agreement.
 
                                       5
<PAGE>
    The Reorganization Agreement provides for the completion of the
Reorganization (the "Closing") in several steps:
 
   
    First, each Institutional Portfolio and the Money Market Portfolio will be
    renamed a "Fund." For example, the Core Growth Institutional Portfolio will
    be renamed the Core Growth Fund.
    
 
   
    Second, the Board of Trustees will create multiple Classes of shares of each
    Fund (other than the Money Market Fund). The current Institutional Portfolio
    shares will be renamed the "Class I" shares. For example, the shares of the
    Core Growth Institutional Portfolio will be renamed the Class I shares of
    the Core Growth Fund. The Board of Trustees will also create new Class A, B,
    C and Q shares of each Fund.
    
 
   
    Third, each master fund will dissolve and distribute its assets in kind
    (i.e., in the form of the stocks, bonds and other investments held by the
    master fund) to the corresponding A, B, C and Qualified Portfolios. The
    Money Market Fund and each Fund which was previously named an Institutional
    Portfolio will also receive assets in kind from the corresponding master
    fund of the Master Trust.
    
 
   
    Fourth, the A, B, C and Qualified Portfolios will transfer their assets to
    the corresponding Fund. For example, the portfolio assets of Core Growth
    Portfolio A will be received from the Core Growth master fund and
    transferred to the Core Growth Fund of the Trust. In exchange, Core Growth
    Portfolio A will receive a similar number of Class A shares of the Core
    Growth Fund.
    
 
    Fifth, each A, B, C and Qualified Portfolio will distribute the Fund shares
    it receives to its shareholders, and will dissolve. For example, Core Growth
    Portfolio A will distribute the Class A shares of the Core Growth Fund to
    its shareholders. Each former shareholder of Core Growth Portfolio A will
    then hold Class A shares of the Core Growth Fund with the same net asset
    value as his Core Growth Portfolio A shares.
 
   
    Finally, Nicholas-Applegate Capital Management, which currently acts as
    investment adviser to the Master Trust, will enter into an Investment
    Advisory Agreement with the Trust with provisions identical in all material
    respects to those of its current investment advisory agreement with the
    Master Trust.
    
 
   
    The Closing is subject to various conditions, including approval of
Proposals 1 and 2, approval of the Reorganization by a majority of shares of
each A, B, C, and Qualified Portfolio, dissolution of the master funds,
completion of all filings with, and receipt of all necessary orders and
approvals from, the Securities and Exchange Commission (the "SEC"), delivery of
legal opinions regarding the Federal tax consequences of the Reorganization, and
other customary corporate and securities matters. Any conditions may be waived
by the Board of Trustees of the Trust if, in its judgment, such waiver will not
have a material adverse effect on the interests of the shareholders. The
Reorganization Agreement may be terminated at any time if the Board of Trustees
determines in good faith that the Reorganization is not in the best interests of
the shareholders.
    
 
FEDERAL TAX CONSEQUENCES
 
   
    The Trust has received an opinion from Paul, Hastings, Janofsky & Walker
LLP, the legal counsel to the Trust, to the effect that under the Internal
Revenue Code the Reorganization will not result in any taxable income to the
Portfolios or their shareholders. This legal opinion is not binding on the
Internal Revenue Service or any other taxing authority, and the Trust does not
intend to seek a private letter ruling or advisory opinion from the Internal
Revenue Service with respect to the tax effects of the Reorganization.
    
 
                                       6
<PAGE>
CHANGE OF FUND NAMES
 
    After the Reorganization is completed, the names of certain of the Funds
will be changed to better reflect their investment objectives and policies, as
follows:
 
<TABLE>
<S>                             <C>               <C>
The Emerging Growth Fund        will become the   Small Cap Growth Fund
The Core Growth Fund            will become the   Mid Cap Growth Fund
The Income & Growth Fund        will become the   Convertible Fund
The Fully Discretionary Fund    will become the   High Quality Bond Fund
</TABLE>
 
COMPARISON OF THE PORTFOLIOS AND THE FUNDS
 
    The Trust is an open-end management investment company currently offering a
number of separate diversified portfolios with differing sales load, shareholder
services plan and distribution plan arrangements. The Trust was organized in
December 1992 as a business trust under the laws of the State of Delaware. If
the Reorganization is approved and completed, shareholders of each Institutional
Portfolio series of the Trust will become Class I shareholders of the same
series (which will be renamed a "Fund"), and shareholders of each A, B, C and
Qualified Portfolio series of the Trust will become shareholders of the similar
Class of the corresponding Fund. The net asset value of the shares of each Class
of a Fund held by a shareholder immediately after the Reorganization will be the
same as the net asset value of the shares of the corresponding Portfolio held by
the shareholder immediately prior to the Reorganization.
 
    A brief comparison of the Portfolios with the new Funds is set forth below:
 
INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
   
    The investment objectives, policies and restrictions under which the assets
of the Portfolios presently are managed will not be affected by the proposed
Reorganization, except that, rather than investing all of its investible assets
in a corresponding master fund of the Master Trust, each Fund will seek to
achieve the same investment objectives by engaging an investment adviser to
directly manage its assets. The investment objectives, policies and restrictions
of the Funds will be the same as those in effect for the Portfolios and the
master fund of the Master Trust immediately prior to the Reorganization.
    
 
INVESTMENT ADVISER
 
   
    The assets of the Master Trust are managed by Nicholas-Applegate Capital
Management (the "Investment Adviser"). The Portfolios currently invest their
assets in the master funds of the Master Trust managed by the Investment
Adviser, and the Portfolios do not themselves engage the services of the
Investment Adviser or any other investment manager. Upon completion of the
Reorganization, the Trust will enter into a new investment advisory agreement
with the Investment Adviser on behalf of each Fund, on terms and conditions
substantially identical to the terms and conditions of the current investment
advisory agreement between the Investment Adviser and the Master Trust.
Accordingly, there will be no separate shareholder vote on the new agreement.
    
 
ADMINISTRATIVE SERVICES
 
    Investment Company Administration Corporation ("ICAC") serves as principal
administrator of the Trust and the Master Trust and, pursuant to Administration
Agreements with the Trust and the Master Trust, is responsible for performing
all administrative services required for the daily business operations of the
Trust and the Master Trust, subject to the supervision of the Board of Trustees
of the Trust and the Master Trust. After the Reorganization, the Master Trust's
Administration Agreement will be terminated and the Trust will enter into a new
Administration Agreement on terms and conditions substantially identical to
those applicable to the Portfolios immediately prior to the Reorganization
except for the fee adjustment described below.
 
                                       7
<PAGE>
   
    The total fees paid to ICAC with respect to the Portfolios and the
corresponding master funds for the fiscal year ended March 31, 1997 were
$554,625 (.04% of the Portfolios' average net assets). Under its new
Administration Agreement with the Trust, ICAC will receive annual fees from each
Fund equal to the Fund's pro rata portion (based on its net assets compared to
the Trust's net assets) of a fee equal to 0.05% of the first $100 million of the
Trust's average net assets, 0.04% of the next $150 million, 0.03% of the next
$300 million, 0.02% of the next $300 million and 0.01% thereafter, subject to a
$40,000 annual minimum. If this fee arrangement had been in effect for the year
ended March 31, 1997, the total fees paid to ICAC with respect to the Portfolios
would have been unchanged -- $554,625 (.04% of the Portfolios' average net
assets).
    
 
    Pursuant to an Administrative Services Agreement with the Trust, the
Investment Adviser is currently responsible for providing all administrative
services to the Trust which are not provided by ICAC or by the Trust's
distributor, transfer agents, accounting agents, independent accountants and
legal counsel. The Administrative Services Agreement will be amended to add the
Funds as parties on terms and conditions substantially identical to the terms
and conditions applicable to the Portfolios immediately prior to the
Reorganization.
 
    PFPC Inc. currently provides day-to-day accounting services to the Trust and
the Master Trust pursuant to Accounting Services Agreement with the Trust and
the Master Trust. After the Reorganization, the Master Trust's Accounting
Services Agreement will be terminated, and the fee schedule for the Trust's
Accounting Services Agreement will be amended.
 
   
    Under its current Accounting Services Agreement with the Trust, PFPC
receives annual fees from each Portfolio of $31,200 and from each corresponding
master fund equal to $6,250 plus 0.03% of average daily net assets from $100
million to $250 million, 0.02% of the next $250 million, and 0.15% thereafter.
The total fees paid to PFPC with respect to the Portfolios and the corresponding
master funds for the fiscal year ended March 31, 1997 were $2,205,940 (.166% of
the Portfolios' average net assets). Under its new fee schedule with the Trust,
PFPC will receive annual fees from each Fund equal to its pro rata portion
(based on its net assets compared to the Trust's net assets) of a fee equal to
$6,250 per Fund plus 0.03% of each Fund's average daily net assets from $100
million to $250 million, 0.02% of the next $250 million, and 0.15% over $500
million. If this arrangement had been in effect for the year ended March 31,
1997, the total fees paid to PFPC with respect to the Portfolios would have been
$1,284,340 (.10% of the Portfolios' average net assets).
    
 
DISTRIBUTOR, TRANSFER AGENT AND CUSTODIAN
 
    Nicholas-Applegate Securities serves as the principal underwriter and
distributor for the Trust pursuant to a Distribution Agreement with the Trust.
State Street Bank and Trust Company serves as the transfer agent for the Trust
pursuant to a Transfer Agency and Services Agreement with the Trust. PNC Bank
serves as the custodian for the Trust pursuant to a Custodian Services Agreement
with the Trust. The Distribution Agreement, the Transfer Agency and Service
Agreement and the Custodian Services Agreement will be amended to incorporate
the multi-class Funds on terms and conditions substantially identical to the
terms and conditions applicable to the Portfolios immediately prior to the
Reorganization. The Master Trust has similar arrangements for which it pays
nominal fees, which will be terminated upon completion of the Reorganization.
 
   
    In addition, securities of many foreign issuers currently owned by the
master funds are held by The Chase Manhattan Bank and certain foreign
sub-custodians, pursuant to a Sub-Custodian Agreement with the Master Trust and
PNC Bank. Upon completion of the Reorganization, the Trust will enter into a
sub-custodian agreement on substantially the same terms.

PRO FORMA EXPENSES
 
   
    As discussed above, the Board of Trustees believes that the Reorganization
will result in substantial expense savings. The following table indicates the
current total annual operating expenses for each Portfolio as a percentage of
average net assets for the fiscal year ended March 31, 1997 (and, for Portfolios
not then in operation, estimated expenses for their first twelve months of
operation), and the pro forma operating expenses for each corresponding Class
assuming the Reorganization had been implemented on that date. It also indicates
the current expense limitations voluntarily imposed by Nicholas-Applegate
Capital Management through March 31, 1999, which would not be changed by the
Reorganization.

    See the accompanying Fund prospectuses for further fee and expense tables
with respect to the Funds, which are unchanged from the current tables for the
various Portfolios as a result of the current voluntary expense limitations. Pro
forma capitalization information has not been included for the various
Portfolios as it would not change from the current information.
    
 
PURCHASES AND REDEMPTIONS
 
   
    Following the Reorganization, shareholders of the Money Market Portfolio and
shareholders of the other Portfolios who receive shares of corresponding Classes
of the Funds in the Reorganization will be able to purchase and redeem shares in
the Funds in substantially the same manner and subject to substantially the same
conditions as shares in the Portfolios presently are purchased and redeemed.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
 
    Following the Reorganization, the Funds will declare and pay dividends and
calculate and make distributions of net capital gains, if any, in a manner
identical to that of the Portfolios.
 
    The Trust has elected to qualify each Portfolio as a regulated investment
company under Subchapter M of the Code, and intends that each Fund will remain
so qualified. As a regulated investment
 
                                       10
<PAGE>
company, upon consummation of the Reorganization each Fund will be entitled to
the same benefits and subject to the same tax regulations as the Portfolios
immediately prior to the Reorganization.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
 
    The Investment Adviser will execute the portfolio transactions and allocate
the brokerage business of the Funds subject to policies established by the Board
of Trustees of the Trust which are substantially identical to those in effect
with respect to the master funds of the Master Trust immediately prior to the
Reorganization.
 
SHAREHOLDERS' RIGHTS
 
   
    The rights of shareholders of the Funds will be identical in all material
respects to those of shareholders of the Portfolios, except that Class B shares
will convert automatically to Class A shares seven years after purchase. As was
the case before the Reorganization, the shareholders of the Trust will vote in
the aggregate on all matters except those affecting only a particular Fund or
Class, in which case only the shareholders of the affected Fund or Class will
vote. Because the Reorganization will increase the size of the Funds, the voting
power of individual shareholders will be diluted with respect to matters on
which shareholders vote on a Fund-wide basis rather than on an individual Class
basis.
    
 
RISK FACTORS
 
   
    The Funds will have investment objectives, policies and restrictions which
are identical to those of the Portfolios and the corresponding master funds of
the Master Trust, except that the Funds will invest their assets directly rather
than through the Master Trust. In addition, the Funds will be administered in
every material respect in a substantially identical manner to the Portfolios.
Consequently, the risks associated with investing in the Funds will be no
different than those associated with investing in the Portfolios.
    
 
FURTHER INFORMATION ABOUT THE PORTFOLIOS AND THE FUNDS
 
    Further information about the Portfolios and the Funds is contained in their
current prospectuses and statements of additional information, which are
incorporated herein by reference. Copies of the relevant Fund prospectuses
accompany this Proxy Statement. The Trust will also provide its most recent
annual reports to shareholders with respect to the Portfolios for the year ended
March 31, 1997, and its semiannual reports to shareholders for the six months
ended September 30, 1997, upon request. These documents are available without
charge by writing to the Trust at 600 West Broadway, San Diego, California
92101, or by calling (800) 551-8045.
 
   
    The Trust is subject to the information requirements of the Securities
Exchange Act of 1934 and the Investment Company Act of 1940, and as required by
those Acts file reports, proxy statements and other information with the
Securities and Exchange Commission. Such reports, proxy statements and other
information can be inspected and copied at the Public Reference Room maintained
by the SEC at 450 Fifth Street, N.W., Washington, D.C., and at the SEC's
regional offices at 219 South Dearborn Street, Chicago, Illinois and 75 Park

APPROVAL OF THE BOARD OF TRUSTEES
 
   
    In reviewing the proposed Reorganization, the Board of Trustees of the Trust
inquired into a number of matters and considered the following factors, among
others: (1) the identity of objectives, policies and restrictions of the Funds
with those of the Portfolios; (2) the cash savings that potentially may be
achieved by collapsing the master-feeder structure into a single, multi-class
fund structure through the elimination of duplicate expenses; (3) the reduced
expenses that potentially may result from the Reorganization;
    
 
                                       11
<PAGE>
(4) the greater likelihood of asset growth that potentially may result from a
more competitive expense ratio, and the greater economies of scale that can be
achieved from such asset growth; (5) the tax-free nature of the Reorganization;
(6) the benefits to Class B shareholders of the automatic conversion of their
shares after seven years to Class A shares without adverse federal tax
consequences; and (7) the terms and conditions of the Reorganization Agreement,
including the agreement of Nicholas-Applegate Capital Management to pay 50% of
the expenses of the Reorganization.
 
   
    The Board of Trustees of the Trust approved the Reorganization on August 15,
1997, subject to shareholder approval. The Board of Trustees determined that the
proposed new structure will eliminate the cost and complexity of maintaining the
master-feeder structure and benefit the shareholders of the Portfolios by
reducing the expense ratios of the Portfolios. In addition to that immediate
benefit to existing shareholders, the Board of Trustees believes this more
competitive expense ratio will make investment in shares of the Funds more
attractive to investors, and will increase the opportunity for further asset
growth. Any such asset growth potentially will enable shareholders of the Funds
to obtain economies of scale by spreading certain expenses over a larger asset
base and, with respect to certain Funds, by potentially reaching an asset
breakpoint in the rate of the investment advisory fee payable to the Investment
Adviser. There can be no assurance, however, that such asset growth and
economies of scale will be realized.
    
 
VOTE REQUIRED
 
   
    Approval of the Reorganization requires the affirmative votes of
shareholders holding more than 50% of the outstanding shares of each of the A,
B, C and Qualified Portfolios. Approval of this Proposal is contingent upon
approval of Proposals 1 and 2. If the shareholders of all the A, B, C and
Qualified Portfolios do not approve the proposed Reorganization, or the
Reorganization is not completed for any other reason, then the Trust will
continue its current form of operation until the Board of Trustees determines
what further action, if any, to recommend to the shareholders.
    
 
   
                       PROPOSAL 4.  ELECTION OF TRUSTEES
    
 
    At the Meeting, shareholders will be asked to elect Trustees of the Trust to
hold office until their successors are elected.
 
   
    The Proxy holders intend to vote for the election of the nominees named
below, all of whom are currently Trustees of the Trust or the Master Trust. All
of the nominees have consented to be named and have indicated their intent to
serve if elected. If any nominee is unavailable for any reason, the Proxy
holders will consult with the Board of Trustees of the Trust in determining how
to vote the shares represented by them.
    
 
    The following table indicates, as to each of the nominees for election as a
Trustee, his or her name, position with the Trust or Master Trust, age,
principal occupation during the past five years, other directorships held in
public companies and the number of shares of the Trust beneficially owned at the
Record Date. Unless otherwise indicated and subject to applicable community
property and similar laws, each nominee has sole voting and investment power
with respect to the shares of the Trust beneficially
 
                                       12

owned. Trustees whose names are followed by an asterisk are "interested persons"
of the Trust (as defined by the Investment Company Act of 1940, as amended).

                      AGREEMENT AND PLAN OF REORGANIZATION
 
   
    This Agreement and Plan of Reorganization (this "Agreement") is made as of
the 1st day of January, 1998, by and among Nicholas-Applegate Mutual Funds, a
Delaware business trust (the "Trust") on behalf of the A, B, C and Qualified
Portfolio series of the Trust other than the Government Income A, B, C and
Qualified Portfolios (each a "Portfolio" and, collectively, the "Portfolios"),
and the Trust on behalf of the corresponding Institutional Portfolio series of
the Trust (each an "Institutional Portfolio" and, collectively, the
"Institutional Portfolios" or "Funds").
    
 
                                   BACKGROUND
 
    WHEREAS, the Portfolios and the Institutional Portfolios are series of the
Trust, a registered open-end management investment company that invests all of
the assets of each Portfolio and Institutional Portfolio in corresponding series
(each such series, a "Master Fund") of Nicholas-Applegate Investment Trust, a
Delaware business trust (the "Master Trust").
 
    WHEREAS, the series of the Master Trust will dissolve and distribute their
assets in kind to the corresponding series of the Trust immediately prior to the
transactions contemplated by this Agreement.
 
   
    WHEREAS, the parties wish to enter into a plan of reorganization (the
"Plan") which will consist of (i) the change by the Board of Trustees of the
Trust (the "Board of Trustees") of the name of each Institutional Portfolio to
replace the phrase "Institutional Portfolio" with the phrase "Fund", (ii)
creation by the Board of Trustees of an "A", "B", "C" and "Q" Class of shares of
each Fund and designation of the existing Institutional Portfolio shares as the
"I" Class shares of the corresponding Fund, (iii) the transfer of the assets of
the Portfolios to the corresponding Fund in exchange for a similar number of A,
B, C or Q Class shares of the Fund (the "Fund Shares"), (iv) distribution by
each of the Portfolios of the Fund Shares to its shareholders and dissolution of
the A, B, C and Qualified Portfolios, and (v) execution of an Investment
Advisory Agreement between the Trust and Nicholas-Applegate Capital Management
("NACM" or the "Investment Adviser") with respect to the Funds.
    
 
    WHEREAS, the Board of Trustees, including a majority of the Trustees who are
not "interested persons" of the Trust as defined in the Investment Company Act
of 1940, as amended (the "1940 Act"), has determined that the Plan is in the
best interests of the shareholders of each of the Portfolios and Institutional
Portfolios and that their interests would not be diluted as a result of the
transactions contemplated thereby.
 
                                   AGREEMENT
 
    NOW THEREFORE, in consideration of the agreements contained in this
Agreement, the parties agree as follows:
 
                                   ARTICLE 1.
                           MULTIPLE CLASSES OF SHARES
 
   
    SECTION 1.1  CREATION OF MULTIPLE CLASSES OF SHARES.  Effective on the
Closing Date, as defined in Article 4, the Board of Trustees shall (a) divide
each Institutional Portfolio into five Classes of shares designated Class A, B,
C, Q and I shares, and (b) classify the shares of each Institutional Portfolio
outstanding immediately prior to the Closing Date as Class I shares.
    
 
    SECTION 1.2  CHANGE IN THE NAME OF INSTITUTIONAL PORTFOLIOS.  Effective on
the Closing Date, the Board of Trustees shall revise the name of each
Institutional Portfolio to replace the phrase "Institutional Portfolio" with the
phrase "Fund".

<PAGE>
                                   ARTICLE 2.
                       TRANSFER OF ASSETS AND LIABILITIES
 
   
    Subject to the terms and conditions set forth herein, on the Closing Date
the Trust shall cause the Portfolios to transfer all of their assets, including
all assets received from the corresponding Master Fund of the Master Trust, to
the corresponding Fund, and shall cause each Fund to assume all of the
liabilities of the corresponding Portfolios. In exchange therefor, the Trust
shall cause each Fund to deliver to each such Portfolio a number of the Fund's
Class A, B, C or Q shares, as applicable, which is equal to (i) the aggregate
net asset value of the corresponding Portfolio determined at the close of
business on the day prior to the Closing Date, divided by (ii) the net asset
value per share of the respective A, B, C or Q Class of shares of the
corresponding Institutional Portfolio outstanding as of the Closing Date.
    
 
                                   ARTICLE 3.
                              SHARES OF THE FUNDS
 
   
    SECTION 3.1  LIQUIDATION OF A, B, C AND QUALIFIED PORTFOLIOS.  Subject to
the terms and conditions set forth herein, on the Closing Date the Trust shall
liquidate each Portfolio and shall distribute pro rata to the shareholders of
record of each Portfolio, determined as of the Closing Date, the Fund Shares
received by such Portfolio pursuant to Article 2.
    
 
   
    SECTION 3.2  ISSUANCE OF SHARE CERTIFICATES.  The Trust shall accomplish the
liquidation and distribution provided for herein by opening accounts on the
books of the corresponding Fund in the names of each Portfolio's shareholders
and transferring the Fund Shares credited to the account of the Portfolio on the
books of the Fund. As promptly as practicable after the Closing, each holder of
any outstanding certificate evidencing shares of a Portfolio or Institutional
Portfolio shall be entitled to surrender the same to the Trust's transfer agent
and request in exchange therefor a certificate or certificates representing the
number of shares of beneficial interest of the Class into which the shares of
beneficial interest theretofore represented by the certificate or certificates
so surrendered shall have been converted. Certificates for fractional shares of
beneficial interests of a Fund shall not be issued, but shall be continued to be
carried by the Funds for the open account of such shareholder. Until so
surrendered, each outstanding certificate which, prior to the Closing,
represented shares of beneficial interest of a Portfolio or Institutional
Portfolio, shall be deemed for all purposes to evidence ownership of the number
of shares of the Class of shares of beneficial interest of the Fund into which
the shares of beneficial interest of such Portfolio or Institutional Portfolio
have been converted.
    
 
    SECTION 3.3  TIME AND DATE OF VALUATION.  The number of shares to be issued
by each Fund to each Portfolio shall be computed as of 4:00 p.m. (Eastern time)
on the Closing Date in accordance with the regular practices of the Trust.
 
                                   ARTICLE 4.
                            CLOSING AND CLOSING DATE
 
   
    SECTION 4.1  CLOSING TIME AND PLACE.  The Closing Date shall be the date on
which all of the conditions set forth in Article 5 have been fulfilled or
otherwise waived by the parties hereto but, in any event, not later than March
31, 1998, or such later date as the parties may mutually agree. All acts taking
place on the Closing Date shall be deemed to be taking place simultaneously as
of the close of business on the Closing Date, unless otherwise provided. The
closing shall be held at 4:30 p.m. (Eastern time) at the offices of the Trust,
600 West Broadway, San Diego, California 92101, or such other time and/or place
as the parties may mutually agree.
    
 
    SECTION 4.2  DELAY OF VALUATION.  If on the Closing Date (a) the primary
trading market for portfolio securities of any Portfolio is closed to trading or
trading thereon is restricted, or (b) trading or the reporting of trading is
disrupted so that an accurate appraisal of the value of the net assets of the
Portfolio
 
                                      B-2
<PAGE>

impracticable, the Closing Date shall be postponed until the first business day
after the day when trading shall have been fully resumed and reporting shall
have been restored.

       Portfolio to the corresponding Fund in exchange for Fund Shares, and the

    3.  No gain or loss will be recognized by any Fund upon the receipt of the

       include the period during which those assets were held by the Portfolio
       and the corresponding Master Fund; and
    
 
   
    9.  The holding period of the Fund Shares to be received by each Portfolio
       shareholder will include the period during which the Portfolio shares
       exchanged therefor were held by such shareholder.

January 12, 1998
    
 
Dear Shareholder:
 
    A special meeting of shareholders of Nicholas-Applegate Mutual Funds (the
"Trust") will be held to determine important organizational issues affecting
your portfolio. The meeting will begin at 9:00 a.m. local time on February 27,
1998, at the offices of the Trust, 600 West Broadway, 30th Floor, San Diego,
California 92101.
 
    At the meeting shareholders of the Trust, other than shareholders of the
Government Income Portfolios, will be asked to consider a reorganization in
which the Trust will move from a complex "master-feeder" structure to a simpler
and more economical "multi-class" structure.
 
    At the same time, shareholders of the Government Income A, B, C and
Qualified Portfolios of the Trust will be asked to consider a reorganization in
which they will receive corresponding Class A, B, C and Q shares of the Fully
Discretionary Fixed Income Fund of the Trust. The goal of the reorganization is
to produce a higher level of income for you from a portfolio comprised
principally of investment grade debt securities. The reorganization should
produce this increased income by spreading overhead costs over a substantially
larger asset base and by giving you the opportunity to benefit from the higher
level of income associated with the Fully Discretionary Fixed Income Fund.
 
    After the reorganization, your shares in the Fully Discretionary Fixed
Income Fund will have exactly the same value as the shares of the Government
Income Portfolio you owned immediately prior to the reorganization. In the
opinion of the Trust's tax counsel, the proposed transaction with have no tax
implications for you.
 
    In addition, shareholders of the Trust will be asked to elect Trustees to
take office when the reorganization is concluded and to ratify the selection of
Ernst & Young L.L.P. as independent public accountants of the Trust.
 
    The proposals have been carefully reviewed by your Board of Trustees, which
recommends that you approve them. Please read the enclosed materials carefully,
and sign, date and mail the enclosed proxy card(s) promptly in the enclosed
return envelope. Your vote is important for the proper administration of the
Trust.
 
   
    Thank you for your attention to this matter. If you have any questions on
voting of proxies or the proposals to be considered at the meeting, please call
us toll free at 1-800-551-8045.

                    COMBINED PROXY STATEMENT AND PROSPECTUS
                     (FOR THE GOVERNMENT INCOME PORTFOLIOS)
 
                            ------------------------
 
    This Combined Proxy Statement and Prospectus, which includes a Notice of
Special Meeting of Shareholders, a Proxy Statement and a form of Proxy, is being
furnished in connection with the special meeting of shareholders of
Nicholas-Applegate Mutual Funds (the "Trust") to be held on February 27, 1998,
and any adjournment thereof (the "Meeting"). It is being furnished to the
shareholders of the Government Income Portfolios of the Trust. Shareholders of
the other portfolios of the Trust are being asked to approve certain related
matters described below, and are being provided with a separate Combined Proxy
Statement and Prospectus in connection with the Meeting.
 
   
    The various portfolios of the Trust currently invest all of their assets in
corresponding "master funds" of Nicholas-Applegate Investment Trust. At the
Meeting the shareholders of the Trust, other than shareholders of the Government
Income Portfolios, will be asked to approve a reorganization in which the Trust
will move from this "master-feeder" structure to a "multi-class" structure. As a
result of the reorganization, each portfolio of the Trust will invest directly
in portfolio securities rather than through the master funds, and each
shareholder of an A, B, C Qualified or Institutional portfolio (other than the
Government Income Portfolios) will receive Class A, B, C, Q or I shares of a
corresponding multi-class series of the Trust.
    
 
    At the Meeting, the shareholders of the Government Income A, B, C, and
Qualified Portfolios will be asked to approve a reorganization in which they
will receive corresponding Class A, B, C and Q shares of the Fully Discretionary
Fixed Income Fund of the Trust.
 
    The shareholders of the Trust also will be asked to elect Trustees of the
Trust and to ratify the selection of Ernst & Young L.L.P. as independent
accountants.
 
    The Trust is an open-end, management investment company comprised of a
number of diversified portfolios. This Combined Proxy Statement and Prospectus
sets forth concisely the information that shareholders of the Government Income
Portfolios of the Trust should know before voting on the proposed reorganization
of those Portfolios and the other matters to be considered at the meeting. It
should be read and retained for future reference.
 
   
    The most recent Prospectus and Statement of Additional Information relating
to each A, B, C and Qualified Government Income Portfolio of the Trust are on
file with the Securities and Exchange Commission and are incorporated by
referenced herein. They are available without charge by writing or calling the
Trust at its address and telephone number above. The Prospectus relating to the
corresponding Class A, B, C, and Q shares of the Fully Discretionary Fixed
Income Fund to be distributed to the shareholders pursuant to the proposed
reorganization accompanies this document. The Statement of Additional
Information relating to the Class A, B, C, and Q shares of the Fully
Discretionary Fixed Income Fund is also incorporated herein and is available
without charge by writing or calling the Trust at its address and telephone
number above.

SOLICITATION OF PROXIES
 
   
    This Combined Proxy Statement and Prospectus (the "Proxy Statement") is
being furnished to the shareholders of the Government Income A, B, C and
Qualified Portfolios (the "Government Income Portfolios") of Nicholas-Applegate
Mutual Funds (the "Trust") in connection with the solicitation of proxies by the
Board of Trustees of the Trust for use at a Special Meeting of Shareholders of
the Trust to be held on February 27, 1998, and any adjournment thereof (the
"Meeting"). Shareholders of the other portfolios of the Trust are being asked to
approve certain related matters described below, and are receiving a separate
combined proxy statement and prospectus in connection with the Meeting.
    
 
   
    The Meeting will be held at the offices of the Trust, 600 West Broadway,
30th Floor, San Diego, California 92101, for the purposes set forth in the
Notice of Special Meeting of Shareholders and more fully described below. This
Proxy Statement and the enclosed form of proxy (the "Proxy") were first mailed
to shareholders entitled to vote at the Meeting on or about January 12, 1998.
    
 
PURPOSE OF MEETING
 
   
    One of the purposes of the Meeting is to permit the shareholders of the
portfolios of the Trust, other than the Government Income Portfolios, to
consider a reorganization (the "Multi-Class Reorganization") in which the
portfolios will move from a "master-feeder" structure to a "multi-class"
structure (Proposal 1). Currently, the A, B, C, Qualified and Institutional
portfolios of the Trust and the Money Market portfolio of the Trust, known as
"feeder funds," invest all of their assets in shares of corresponding funds,
known as "master funds," of Nicholas-Applegate Investment Trust (the "Master
Trust"). As a result of the Multi-Class Reorganization the Trust will manage its
assets directly rather than through the Master Trust, and each shareholder of a
Nicholas-Applegate A, B, C, Qualified or Institutional portfolio (other than the
Government Income Portfolios) will receive Class A, B, C, Q or I shares of a
corresponding multi-class series of the Trust. The Money Market portfolio of the
Trust will not have multiple classes, and the series of the Trust created after
August 1, 1997 (the Global Blue Chip Bond Fund, Emerging Markets Bond Fund,
Pacific Rim Fund, Greater China Fund and Latin America Fund) are not part of the
master-feeder structure and will not be affected by the Multi-Class
Reorganization. The Board of Trustees and management of the Trust believe that
the Multi-Class Reorganization will result in substantial economies for the
Trust.
    
 
   
    As a related matter, the shareholders of the Institutional portfolios and
the Money Market portfolio will be asked to authorize the Board of Trustees to
eliminate each such portfolio's current policy of investing substantially all of
its assets in the corresponding master fund (Proposal 2).
    
 
   
    Another purpose of the Meeting is to permit the shareholders of the
Government Income A, B, C and Qualified Portfolios of the Trust to consider a
reorganization (the "Government Income Portfolios Reorganization") in which they
will receive corresponding Class A, B, C and Q shares of the Fully Discretionary
Fixed Income Fund series of the Trust (Proposal 3). The Board of Trustees and
management of the Trust believe that the Government Income Portfolios
Reorganization will result in a higher level of income for shareholders of the
Government Income Portfolios from a portfolio comprised principally of
investment grade debt securities.
    
 
   
    All shareholders of the Trust will also be asked to act on two other
matters--the election of Trustees to take office when the Multi-Class
Reorganization is concluded (Proposal 4) and ratification of the selection of
Ernst & Young L.L.P. as independent public accountants to the Trust (Proposal
5).
    
 
   
    Nicholas-Applegate Capital Management (the "Investment Adviser") will bear
50% of the cost of solicitation of proxies, including the cost of printing,
preparing, assembling and mailing the Notice of Meeting, Proxy Statement and
form of Proxy, and the balance will be paid by the Trust (allocated among the
various series of the Trust in proportion to their net assets). In addition to
solicitations by mail, proxies
    
 
                                       1
<PAGE>
may be solicited by officers and regular employees of the Trust and the
Investment Adviser by personal interview, by telephone or by facsimile. Tritech
will also be retained to provide professional proxy solicitation services. The
cost of solicitation, including specified expenses, is not expected to exceed
$20,000.
 
                               SHARES AND VOTING
 
    The presence in person or by proxy of more than one-third of the outstanding
shares of beneficial interest of the Trust entitled to vote at the Meeting will
constitute a quorum. If a quorum is not present at the Meeting, sufficient votes
in favor of the Proposals set forth in the Notice of Meeting are not received by
the time scheduled for the Meeting, or the holders of shares present in person
or by proxy determine to adjourn the Meeting for any other reason, the
shareholders present in person or by proxy may adjourn the Meeting from time to
time, without notice other than announcement at the Meeting. Any such
adjournment will require the affirmative vote of shareholders holding a majority
of the shares present in person or by proxy at the Meeting. The persons named in
the Proxy will vote in favor of adjournment those shares which they represent if
adjournment is necessary to obtain a quorum or to obtain a favorable vote on any
Proposal. Business may be conducted once a quorum is present and may continue
until adjournment of the Meeting notwithstanding the withdrawal or temporary
absence of sufficient shares to reduce the number present to less than a quorum.
 
    Each shareholder is entitled to one vote for each full share and a
fractional vote for each fractional share outstanding on the books of the Trust
in the name of the shareholder or his or her nominee on the Record Date. The
Record Date and time for determining those entitled to notice of and to vote at
the Meeting has been fixed at the close of business on December 19, 1997.
 
   
    At the Record Date, the Trust had 60 series of shares and 236,442,334,025
total shares outstanding, of which 738,324,661 were shares of the Government
Income Portfolios. At the Record Date, the following persons owned of record
more than 5% of the outstanding shares of the Government Income Portfolios and
of the Trust as a whole:
    
 
    The Trust has no information regarding the beneficial owners of such shares
at the Record Date. Except as indicated above, the officers and Trustees of the
Trust as a group beneficially owned less than 1% of the outstanding shares of
each of the Government Income Portfolios and the Trust as a whole at the Record
Date.
 
   
    All shares represented by each properly signed Proxy received prior to the
Meeting will be voted at the Meeting. If a shareholder specifies how the Proxy
is to be voted on a Proposal to be considered at the Meeting, it will be voted
as specified. If no direction is made on the Proxy, the Proxy will be voted FOR
the Proposals described in this Proxy Statement. Shareholders voting to ABSTAIN
on a Proposal will be treated as present for purposes of achieving a quorum and
in determining the votes cast on the Proposal. A properly signed Proxy on which
a broker has indicated that it has no authority to vote on a Proposal on behalf
of the beneficial owner (a "broker non-vote") will be treated as present for
purposes of achieving a quorum but will not be counted in determining the votes
cast on the Proposal.
    
 
   
    A Proxy may be revoked by a shareholder at any time prior to its use by
written notice to the Trust, by submission of a later dated proxy or by voting
in person at the Meeting. If any other matters come before the Meeting, Proxies
will be voted by the persons named in the Proxy in accordance with their best
judgement.
    
 
   
    Proposals 1 and 2 affect only the shareholders of the Institutional and
Money Market portfolios of the Trust and will not be submitted to the
shareholders of the Government Income Portfolios. Shareholders of each A, B, C,
and Qualified Government Income Portfolio will vote separately with respect to
Proposal 3. All of the shareholders of the Trust will vote in the aggregate with
respect to Proposals 4 and 5.

                  BACKGROUND OF THE PROPOSED GOVERNMENT INCOME
                           PORTFOLIOS REORGANIZATION
 
THE MULTI-CLASS REORGANIZATION
 
   
    Unlike other mutual funds that acquire their securities directly, the
portfolios of the Trust created prior to August 1, 1997 invest their assets in
funds of the Master Trust. This two-tier structure is known as a "master-feeder"
structure and it permits one or more feeder funds that have the same investment
objectives but different operating characteristics (such as sales charges,
expenses and investment minimums) to invest in the same master fund.
    
 
   
    When the Board of Trustees of the Trust established the master-feeder
structure in 1993, it believed this form of organization would achieve certain
efficiencies of operation and economies of scale. However, since the
establishment of the master-feeder structure, the number of portfolios organized
by the Trust using that structure has increased significantly, to 57.
Furthermore, regulatory developments have occurred enabling mutual fund
complexes to more easily achieve, through the use of multiple classes of shares,
the benefits at one time expected of the master-feeder approach without the
operating costs and technical complexities of a two-tiered structure.
    
 
   
    The purpose of the Multi-Class Reorganization is to eliminate the cost and
complexity of a master-feeder structure that has not yielded and is no longer
expected to yield long-term efficiencies of operation and economies of scale.
Management of the Trust expects the Multi-Class Reorganization to save the Trust
approximately $1,000,000 per year in fees currently paid to the company which
provides day-to-day accounting services to the Trust. In addition, the number of
tax returns currently filed annually by the Trust and the Master Trust would be
reduced from 129 to 38 and separate audits for the master funds would no longer
be necessary, with an annual savings of approximately $180,000. Over time the
Trust would also benefit from the fewer number of required SEC filings and other
legal and administrative cost savings.
    
 
   
    As Investment Adviser to the Master Trust, Nicholas-Applegate Capital
Management has to date voluntarily agreed to defer its management fees and to
absorb other operating expenses payable by the Trust and the Master Trust, to
the extent necessary to ensure that the expenses for each portfolio (other than
interest, taxes, brokerage commissions and other portfolio transaction expenses,
capital expenditures and extraordinary expenses) do not exceed certain levels.
Accordingly, the shareholders of the Trust have in the past not borne the full
cost of the master-feeder structure. However, the Board of Trustees believes
that the Multi-Class Reorganization will benefit the shareholders of the Trust.
Any expenses in excess of the current expense caps may be borne by the
shareholders in the future, as in subsequent years each portfolio will reimburse
the Investment Adviser when operating expenses (before recoupment) for the
portfolio are less than the expense cap. Furthermore, although the Investment
Adviser has maintained these expense caps since the portfolios commenced
operation and has agreed to maintain them through March 31, 1999 there can be no
assurance it will do so indefinitely in the future.
    
 
    In addition, the proposed Multi-Class Reorganization will permit the Trust
to provide for the automatic conversion of its current portfolio B shares to
portfolio A shares seven years after purchase. Although portfolio B shares may
currently be exchanged voluntarily for the corresponding portfolio A shares
seven years after purchase, the exchange is treated as a redemption and purchase
for tax purposes. In the proposed multi-class structure, the Trust will be able
to provide for automatic conversion without adverse federal income tax
consequences. Such an exchange is beneficial for long-term shareholders, as
portfolio A shares have lower annual distribution-related fees than portfolio B
shares.
 
    Upon completion of the Multi-Class Reorganization, the current Fully
Discretionary Fixed Income Institutional Portfolio of the Trust will be renamed
the "Fully Discretionary Fixed Income Fund," the shareholders of the Portfolio
will become Class I shareholders of the Fund, and the Board of Trustees will
create Class A, B, C and Q shares of the Fund to enable the Government Income
Portfolios Reorganization to be completed.
 
                                       3

THE GOVERNMENT INCOME PORTFOLIOS REORGANIZATION
 
    The Board of Trustees of the Trust believes that, at their current sizes
(ranging from $4,283,869 to $17,075 as of October 31, 1997), the Government
Income A, B, C and Qualified Portfolios, and the corresponding Government Income
master fund in which the Government Income Portfolios invest, are too small to
operate in a cost effective manner. The Government Income Portfolios incur
substantial overhead expenses, directly and through their investment in the
Government Income master fund, for accounting services, legal services,
printing, insurance, and custodial, transfer agency, advisory and administrative
services. To date, Nicholas-Applegate Capital Management has been voluntarily
subsidizing the Government Income Portfolios' operations by reducing its
management fees to the Government Income master fund and by absorbing some of
the other expenses of the master fund and the Portfolios, in order that the
Government Income Portfolios can provide competitive yields to their
shareholders. Management of the Trust does not foresee any significant increases
in the assets of the Government Income Portfolios or the Government Income
master fund in the near future, and Nicholas-Applegate Capital Management has
informed the Board that it is unwilling to continue subsidizing the Government
Income Portfolios' operations in the future despite any economies achieved in
connection with the Multi-Class Reorganization.
 
    The Fully Discretionary master fund had aggregate assets of $14,665,285
million as of October 31, 1997, compromised principally of assets of the Fully
Discretionary Fixed Income Institutional Portfolio of the Trust. The Fully
Discretionary Fixed Income Institutional Portfolio and the corresponding Fully
Discretionary Fixed Income master fund currently incur expenses similar to those
of the Government Income Portfolios and the Government Income master fund.
However, management believes that as a result of the proposed Multi-Class
Reorganization and the proposed Government Income Portfolios Reorganization, the
combined asset base of the Fully Discretionary Fund will permit the Fund to
spread reduced expenses over a larger asset base, with reasonable prospects for
further increases in assets in the future. Because the investment objectives of
the Government Income Portfolios and the Fully Discretionary Fixed Income Fund
are similar, the Board of Trustees believes that shareholders of the Government
Income Portfolios should be able to continue to meet their primary goal of
current income from a portfolio comprised principally of high quality fixed
income securities after completion of the Government Income Portfolios
Reorganization.
 
    The Board of Trustees believes that the only practical alternative to the
proposed Government Income Portfolios Reorganization would be a taxable
liquidation of the Portfolios, which would not be preferable to the proposed
tax-free reorganization with the Fully Discretionary Fund.

INVESTOR EXPENSES
 
   
    Investors pay various expenses, either directly or indirectly. The figures
below are expenses for each Government Income Portfolio (including their shares
of the expenses of the corresponding Government Income master fund) for the
fiscal year ended March 31, 1997. No Fully Discretionary Fixed Income A, B, C or
Qualified Portfolios currently exist, so the figures set forth below for the A,
B, C and Q Classes of the Fully Discretionary Fund are expected expenses for the
first year of operation of the Fund.

(2) The Investment Adviser has voluntarily agreed to defer its management fees
    and to absorb other operating expenses payable by the master funds and the
    Portfolios through March 31, 1999, and will do so for the various Classes of
    the Fully Discretionary Fixed Income fund through March 31, 1999. For the
    Government Income A, B, C and Qualified Portfolios, Total operating expenses
    would have been 7.67%, 8.33%, 4.98% and 2,789.64%, respectively, and Other
    expenses would have been 7.02%, 7.43%, 4.08%, and 2,788.99%, respectively,
    absent the deferral. For the Class A, B, C and Q shares of the Fully
    Discretionary Fixed Income Fund, expected Total operating expenses are
    6.18%, 4.35%, 3.92% and 268.01%, respectively, and estimated Other expenses
    are 5.53%, 3.45%, 3.02%, and 267.36%, respectively, absent the deferral.
    Because of the 12b-1 fees, long-term shareholders may indirectly pay more
    than the equivalent of the maximum permitted front-end sales charge.

                 PROPOSAL 1.  AMENDMENT OF DECLARATION OF TRUST
 
   
    At the Meeting, shareholders of the Institutional Portfolios of the Trust
(including the Fully Discretionary Fixed Income Institutional Portfolio) will be
asked to approve an amendment to the Trust's Declaration of Trust to permit the
Board of Trustees to create multiple classes of the Institutional Portfolios. As
this Proposal affects only the Institutional Portfolios, it is not being
submitted to the shareholders of the Government Income Portfolios.
    
 
   
                 PROPOSAL 2.  AMENDMENT OF INVESTMENT POLICIES
    
 
   
    At the Meeting, shareholders of the Money Market portfolio and the
Institutional portfolios will be asked to authorize the Board of Trustees to
eliminate each such portfolio's current policy of investing all of its assets in
the corresponding master fund of the Master Trust. As this Proposal affects only
the Money Market and Institutional portfolios, it is not being submitted to the
shareholders of the Government Income Portfolios.
    
 
   
            PROPOSAL 3.  APPROVAL OF THE PROPOSED GOVERNMENT INCOME
                           PORTFOLIOS REORGANIZATION
    
 
    At the Meeting, shareholders of the A, B, C, and Qualified Government Income
Portfolios will be asked to approve the proposed Government Income Portfolios
Reorganization.
 
DESCRIPTION OF THE PROPOSED GOVERNMENT INCOME PORTFOLIOS
  REORGANIZATION
 
THE REORGANIZATION AGREEMENT
 
    The terms and conditions under which the proposed Government Income
Portfolios Reorganization will be completed are set forth in the Agreement and
Plan of Reorganization (the "Reorganization Agreement") attached as Appendix A.
The following is a summary of the Reorganization Agreement.
 
    The Reorganization Agreement provides for the completion of the Government
Income Portfolios Reorganization (the "Closing") in several steps:
 
        First, upon completion of the Multi-Class Reorganization, the Fully
    Discretionary Fixed Income Institutional Portfolio will be renamed the
    "Fully Discretionary Fixed Income Fund," and its existing shares will be
    designated Class I shares of the Fund.
 
   
        Second, the Government Income master fund will dissolve and distribute
    its assets in kind (i.e., in the form of the bonds or other investment
    securities held by the master fund) to the A, B, C and Qualified Government
    Income Portfolios.
    
 
   
        Third, the A, B, C and Qualified Government Income Portfolios will
    transfer their assets to the Fully Discretionary Fixed Income Fund, which
    assets will be managed in the same manner as other Fund investments. In
    exchange, each Government Income Portfolio will receive Class A, B, C or Q
    shares of the Fully Discretionary Fixed Income Fund with the same total net
    asset value as the assets being transferred.
    
 
        Finally, each A, B, C and Qualified Government Income Portfolio will
    distribute the Fully Discretionary Fixed Income Fund shares it receives to
    its shareholders, and will dissolve. For example, Government Income
    Portfolio A will distribute the Class A shares of the Fully Discretionary
    Fixed Income Fund to its shareholders. Each former shareholder of Government
    Income Portfolio A will then hold Class A shares of the Fully Discretionary
    Fixed Income Fund with the same net asset value as the shares of the
    Government Income Portfolio A he previously held.
 
                                       7
<PAGE>
   
    The Closing is subject to various conditions, including the completion of
the Multi-Class Reorganization, approval of the Government Income Portfolios
Reorganization by a majority of shares of each A, B, C, and Qualified Government
Income Portfolio, dissolution of the Government Income master fund, completion
of all filings with, and receipt of all necessary orders and approvals from, the
Securities and Exchange Commission (the "SEC"), delivery of legal opinions
regarding the Federal tax consequences of the Government Income Portfolios
Reorganization, and other customary corporate and securities matters. Any
conditions may be waived by the Board of Trustees of the Trust if, in its
judgment, such waiver will not have a material adverse effect on the interests
of the shareholders. The Reorganization Agreement may be terminated at any time
if the Board of Trustees determines in good faith that the Government Income
Portfolios Reorganization is not in the best interests of the shareholders of
the Government Income Portfolios or the Fully Discretionary Fixed Income Fund.
    
 
FEDERAL TAX CONSEQUENCES
 
   
    The Trust has received an opinion from Paul, Hastings, Janofsky & Walker
LLP, the legal counsel to the Trust, to the effect that under the Internal
Revenue Code the Government Income Portfolios Reorganization will not result in
any taxable income to the Government Income Portfolios or their shareholders.
This legal opinion is not binding on the Internal Revenue Service or any other
taxing authority, and the Trust does not intend to seek a private letter ruling
or advisory opinion from the Internal Revenue Service with respect to the tax
effects of the Government Income Portfolios Reorganization.
    
 
CHANGE OF FUND NAME
 
    After the Multi-Class Reorganization and the Government Income Portfolios
Reorganization are completed, the Fully Discretionary Fixed Income Fund will be
renamed the High Quality Bond Fund, to better reflect its investment objective
and policies.
 
COMPARISON OF THE GOVERNMENT INCOME PORTFOLIOS AND THE FULLY
  DISCRETIONARY FIXED INCOME FUND
 
   
    The Trust is an open-end management investment company currently offering a
number of separate diversified portfolios with differing sales load, shareholder
services plan and distribution plan arrangements. The Trust was organized in
December 1992 as a business trust under the laws of the State of Delaware. If
the Multi-Class Reorganization is approved and completed, shareholders of each
Institutional portfolio series of the Trust will become Class I shareholders of
the same series (which will be renamed a "Fund"), and shareholders of each A, B,
C and Qualified portfolio series of the Trust will become Class A, B, C and Q
shareholders of the corresponding Fund.
    
 
   
    Pursuant to the Multi-Class Reorganization, the Fully Discretionary Fixed
Income Institutional Portfolio of the Trust will be renamed the "Fully
Discretionary Fixed Income Fund" of the Trust, and its existing shareholders
will hold Class I shares of the Fully Discretionary Fixed Income Fund. As a
result of the proposed Government Income Portfolios Reorganization, each
shareholder of an A, B, C, or Qualified Government Income Portfolio will hold
Class A, B, C or Q shares of the Fully Discretionary Fixed Income Fund with the
same net asset value as his current shares.
    
 
    A brief comparison of the Government Income Portfolios with the Fully
Discretionary Fixed Income Fund is set forth below:
 
INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS
 
    The Government Income Portfolios seek, as their investment objective,
current income consistent with prudent investment risk and preservation of
capital. They invest (through the Government Income master fund) primarily in
intermediate term government bonds. The Fully Discretionary Fixed Income Fund
seeks to maximize total return through an actively managed diversified portfolio
of debt securities.
 
                                       8
<PAGE>
    Under normal conditions, the Government Income Portfolios, through the
Government Income master fund, invest at least 75% of their total assets in
securities issued by the U.S. Government and its agencies and instrumentalities.
They invest the remainder primarily in non-agency mortgage-related securities,
domestic and foreign investment grade debt obligations and short-term
investments. The Fully Discretionary Fixed Income Fund, under normal conditions,
invests at least 65% of its total assets in investment grade debt securities
issued by U.S. and foreign corporations and U.S. and foreign governments and
their agencies and instrumentalities. In addition, unlike the Government Income
Portfolios, the Fully Discretionary Fixed Income Fund may invest in municipal
debt securities and may invest up to 20% of its assets in debt securities rated
below investment grade.
 
   
    The investment policies of the Government Income Portfolios and the Fully
Discretionary Fixed Income Fund also differ in certain other significant
respects. Both the Government Income Portfolios and the Fully Discretionary
Fixed Income Fund may enter into interest rate or financial futures contracts
and into foreign currency futures contracts (and options on those futures
contracts) as hedging techniques. However, the Fully Discretionary Fixed Income
Fund may also write covered call and secured put options on securities and
securities indexes and may enter into interest rate and currency swaps as
hedging techniques, subject to the limitation that it may not enter into such
hedging transactions if as a result more than 25% of its net assets would be
hedged or more than 25% of its net assets would be used as cover for options it
has written. In addition to hedging transactions, the Fully Discretionary Fixed
Income Fund may enter into options, futures and swap transactions to enhance
potential gains in circumstances where hedging is not involved, provided that
its net loss exposure from such transactions does not exceed 5% of its net
assets at any time.
    
 
RISK FACTORS
 
    As noted above, the investment objectives, policies and restrictions of the
Government Income Portfolios and the Fully Discretionary Fund differ in some
respects. As a result of these differences, an investment in the Fully
Discretionary Fixed Income Fund involves greater risk than an investment in a
Government Income Portfolio.
 
   
    The values of both the Government Income Portfolios' and the Fully
Discretionary Fixed Income Fund's portfolios fluctuate in response to movements
in interest rates. However, the average duration of the Fully Discretionary
Fixed Income Fund's portfolio will range from two to eight years, compared to
three to six years for the Government Income Portfolios. Although longer
maturity securities generally have higher yields, they also have greater
fluctuations in price. In addition, by including in its portfolio a greater
portion of securities issued by domestic and foreign companies, states and
municipalities, the Fully Discretionary Fixed Income Fund incurs market and
credit risks, in addition to interest rate risks, that are greater than those
incurred by the Government Income Portfolios, which have investment portfolios
consisting primarily of securities issued by the U.S. Government and its
agencies and instrumentalities. Although at least 65% of the Fully Discretionary
Fixed Income Fund's total assets will be comprised of investment grade
securities, the prices of such securities are likely to change more than those
of U.S. Government securities, and thus the net asset values of the Fund's
shares are likely to move more in price than those of the Government Income
Portfolios. Furthermore, credit ratings of portfolio securities are heavily
weighted by past developments and do not necessarily reflect probable future
conditions, securities in the lower investment grades have speculative
characteristics, and changes in economic conditions or other circumstances may
be more likely to lead to the issuers' weakened capacity to pay interest and
principal than would be the case with higher rated investment grade securities.
    
 
    In addition, the Fully Discretionary Fixed Income Fund may invest up to 20%
of its assets in debt and convertible securities rated below investment grade.
Securities rated below investment grade, commonly referred to as "junk bonds" or
"high-yield, high risk bonds," are subject to greater risk of loss of income and
principal than higher rated bonds and are considered to be predominantly
speculative. The issuers' capacity to pay interest and repay principal may
decline during sustained periods of deteriorating
 
                                       9
<PAGE>
economic conditions or rising interest rates, and such bonds are subject to
wider market and yield fluctuations than higher-rated securities. The markets
for such securities may be thinner and less active than higher-rated securities,
which can adversely affect the prices at which the securities can be sold and
the Fund's ability to accurately price the securities. The Fund may purchase
securities with any rating (or comparable unrated securities), including
securities currently in payment default. Although Nicholas-Applegate Capital
Management (the "Investment Adviser") will attempt to identify those issuers of
high-yielding securities whose financial condition is adequate to meet future
obligations, there can be no assurance that losses will not occur.
 
   
    Furthermore, the Fully Discretionary Fixed Income Fund may invest an
unlimited portion of its portfolio in securities of foreign companies and
governments, compared to a limit of 35% for the Government Income Portfolios.
Such investments bear special risks, including fluctuations in foreign exchange
rates, political or economic instability in the country of issue, and the
possible imposition of exchange controls or other laws or restrictions. In
addition, securities prices in foreign markets are generally subject to
different economic, financial, political, and social factors than are the prices
of securities in the United States markets. With respect to some foreign
countries there may be the possibility of expropriation or confiscatory
taxation, limitations on liquidity of securities or political or economic
developments which could affect foreign investments. Moreover, securities of
foreign issuers generally will not be registered with the Securities and
Exchange Commission and such issuers generally will not be subject to the
Commission's reporting requirements. Accordingly, there is likely to be less
publicly available information concerning certain of the foreign issuers of
securities than is available concerning U.S. companies. Foreign companies are
also generally not subject to uniform accounting, auditing and financial
reporting standards or to practices and requirements comparable to those
applicable to U.S. companies. There may also be less government supervision and
regulation of foreign broker-dealers, financial institutions and listed
companies than exists in the United States. Neither the Government Income
Portfolios nor the Fully Discretionary Fixed Income Fund will invest in
securities denominated in a foreign currency unless, at the time of investment,
such currency is considered by the Investment Adviser to be fully exchangeable
into United States dollars without significant legal restriction; if such
restrictions develop after an investment is made, the Investment Adviser will
take such actions as it concludes are appropriate under the circumstances.
    
 
   
    The Fully Discretionary Fixed Income Fund may invest in securities issued by
state and local governments, territories and possessions of the U.S., regional
government authorities, and their agencies and instrumentalities ("municipal
securities"), including general obligation and revenue bonds. The issuers of
municipal securities may become subject to laws enacted in the future by state
or local legislative bodies or referenda extending the time for payment of
principal or interest, or imposing other constraints upon enforcement of such
obligations or upon the ability of the issuers to levy taxes. Furthermore, as a
result of legislation or other conditions, the power or ability of any issuer to
pay, when due, the principal of or interest on its municipal obligations may be
materially affected.
    
 
   
    The Fully Discretionary Fixed Income Fund may use options on securities and
securities indexes for hedging purposes and in non-hedging transactions to
enhance potential gain. There is a risk that the prices of the options may not
correlate perfectly with the prices of the securities in its portfolio. This may
cause the options to react differently than the Fund's portfolio securities to
market changes. In addition, the Investment Adviser could be incorrect in its
expectations about the direction or extent of market movements, in which case
the Fund could lose money on an option. The Fund may also use dealer options,
which lack the liquidity of exchange traded options and involve the risk that
the securities dealers participating in the transactions will fail to meet their
obligations. Although the Investment Adviser will consider liquidity before
entering into options transactions, there is no assurance that a liquid
secondary market will exist for these instruments, which could prevent the Fund
from liquidating an unfavorable position.
    
 
                                       10
<PAGE>
    Interest rate and currency swap transactions in which the Fully
Discretionary Fixed Income Fund may invest require the Fund to rely on the other
party to the transaction to perform its obligations pursuant to the swap
agreement. In the event of a default by the other party, the Fund would have
contractual remedies against the defaulting party but there is no assurance that
the Fund would be able to obtain the expected benefit from the transaction.
 
INVESTMENT ADVISER
 
   
    All of the Portfolios of the Trust, including the Government Income
Portfolios, currently invest their assets in the corresponding series of the
Master Trust managed by the Investment Adviser, and the Portfolios do not
themselves engage the services of the Investment Adviser or any other investment
manager. Upon completion of the Multi-Class Reorganization, the Trust will enter
into a new investment advisory agreement with the Investment Adviser on behalf
of all of its portfolios, including the Fully Discretionary Fixed Income Fund,
on terms and conditions identical in all material respects to the terms and
conditions of the current investment advisory agreement between the Investment
Adviser and the Master Trust.
    
 
    The investment advisory fees currently paid by the Government Income
Portfolios will increase slightly as a result of the proposed Government Income
Portfolios Reorganization. As compensation for the services it provides to the
Government Income master fund, the Investment Adviser receives a monthly fee at
the rate of 0.40% of the first $500 million of the master fund's net assets, and
0.35% of net assets in excess of $500 million. As compensation for the services
it provides to the Fully Discretionary Fixed Income Fund, the Investment Adviser
will receive a monthly fee at the rate of 0.45% of the first $500 million of the
Fund's average net assets, 0.40% of the next $250 million of average net assets,
and 0.35% of average net assets in excess of $750 million.
 
   
    The expense cap voluntarily applied by the Investment Adviser to the Fully
Discretionary Fixed Income Fund will be higher than the expense cap currently
voluntarily applied to the Government Income Portfolios. To limit the expenses
of the Government Income Portfolios, the Investment Adviser has voluntarily
agreed to defer its fees payable by the Government Income master fund, and to
absorb other operating expenses payable by the master fund and the Government
Income Portfolios, through March 31, 1999, to ensure that the expenses allocable
to each Portfolio (excluding interest, taxes, brokerage commission and other
portfolio transaction expenses, capital expenditures and extraordinary expenses,
but including the Portfolio's proportionate share of the master fund's similar
operating expenses) do not exceed the following respective percentages of the
Portfolios' average net assets on an annual basis: Portfolio A--0.90%; Portfolio
B--1.30%; Portfolio C--1.30%; Qualified Portfolio--0.80%. To limit the expenses
of the various Classes of the Fully Discretionary Fixed Income Fund, the
Investment Adviser has voluntarily agreed to similar expense deferrals through
March 31, 1999, as follows: Class A--1.30%; Class B--1.70%; Class C--1.70%,
Class Q--0.88%. As was the case with the Government Income Portfolios, each
Class of the Fully Discretionary Fixed Income Fund will reimburse the Investment
Adviser for fees deferred or other expenses paid in later years in which
operating expenses for the Class are less than the applicable percentage
limitation for any such year. In both cases, no interest, carrying or finance
charge will be paid with respect to any amounts representing fees deferred or
other expenses paid by the Investment Adviser. In addition, in both cases
unreimbursed amounts will not be payable upon termination or non-renewal of the
investment advisory agreement. Although the limitations are voluntary, they have
been in effect since the inception of the Government Income Portfolios and Fully
Discretionary Fixed Income Institutional portfolio, and the Investment Adviser
has no current intention of terminating the limitations applicable to the
Classes of the Fully Discretionary Fixed Income Fund.
    
 
ADMINISTRATIVE SERVICES
 
    Investment Company Administration Corporation ("ICAC") currently serves as
the principal administrator of the Trust and the Master Trust and, pursuant to
Administration Agreements with the Trust and
 
                                       11
<PAGE>
   
the Master Trust, is responsible for performing all administrative services
required for the daily business operations of the Trust and the Master Trust,
subject to the supervision of the Board of Trustees of the Trust and the Master
Trust. After the Multi-Class Reorganization, the Master Trust's Administration
Agreement will be terminated, and the Trust will enter into a new Administration
Agreement on terms and conditions substantially identical to those applicable to
the portfolios immediately prior to the Multi-Class Reorganization, except for
the fee adjustments described below.
    
 
   
    The total fees paid to ICAC with respect to the Government Income Portfolios
and the Government Income master fund for the fiscal year ended March 31, 1997
were $27,846 (.58% of the Government Income Portfolios' average net assets).
Under its new Administration Agreement with the Trust, ICAC will receive annual
fees from the Fully Discretionary Fund equal to the Fully Discretionary Fund's
pro rata portion (based on its net assets compared to the Trust's total net
assets) of a fee equal to 0.05% of the first $100 million of the Trust's average
net assets, 0.04% of the next $150 million, 0.03% of the next $300 million,
0.02% of the next $300 million and 0.01% thereafter, subject to a $40,000 annual
minimum. If this fee arrangement had been in effect for the year ended March 31,
1997, the total fees paid to ICAC with respect to the Government Income
Portfolios would have been unchanged--$27,846 (.58% of average net assets).
    
 
   
    Pursuant to an Administrative Services Agreement with the Trust, the
Investment Adviser is currently responsible for providing all administrative
services to the Trust which are not provided by ICAC or by the Trust's
distributor, transfer agents, accounting agents, independent accountants and
legal counsel. The Administrative Services Agreement will be amended to add the
Funds (including the Fully Discretionary Fixed Income Fund) as parties on terms
and conditions substantially identical to the terms and conditions applicable to
the portfolios immediately prior to the Multi-Class Reorganization.
    
 
    PFPC Inc. currently provides day-to-day accounting services to the Trust and
the Master Trust pursuant to Accounting Services Agreement with the Trust and
the Master Trust. After the Multi-Class Reorganization, the Master Trust's
Accounting Services Agreement will be terminated, and the fee schedule for the
Trust's Accounting Services Agreement will be amended.
 
   
    Under its current Accounting Services Agreement with the Trust, PFPC
receives annual fees from the Government Income Portfolios aggregating $50,664
and from the Government Income master fund equal to $6,250 plus 0.03% of average
daily net assets from $100 million to $250 million, 0.02% of the next $250
million, and 0.15% thereafter. The total fees paid to PFPC with respect to the
Government Income Portfolios and the Government Income master fund for the
fiscal year ended March 31, 1997 were $114,358 (2.4% of the Government Income
Portfolios' average net assets). Under its new fee schedule with the Trust, PFPC
will receive annual fees from the Fully Discretionary Fund equal to its pro rata
portion (based on its net assets compared to the Trust's total net assets) of a
fee equal to $6,250 per Fund plus 0.03% of each Fund's average daily net assets
from $100 million to $250 million, 0.02% of the next $250 million, and 0.15%
over $500 million. If this arrangement had been in effect for the year ended
March 31, 1997, the total fees paid to PFPC with respect to the Government
Income Portfolios would have been $75,497 (.82% of average net assets).
    
 
DISTRIBUTOR, TRANSFER AGENT AND CUSTODIAN
 
   
    Nicholas-Applegate Securities currently serves as the principal underwriter
and distributor for the Trust pursuant to a Distribution Agreement with the
Trust, State Street Bank and Trust Company currently serves as the transfer
agent for the Trust pursuant to a Transfer Agency and Services Agreement with
the Trust, and PNC Bank currently serves as the custodian for the Trust pursuant
to a Custodian Services Agreement with the Trust. The Distribution Agreement,
the Transfer Agency and Service Agreement and the Custodian Services Agreement
will be amended to add the Funds (including the Fully Discretionary Fixed Income
Fund) as parties to each on terms and conditions substantially identical to the
terms and conditions applicable to the portfolios immediately prior to the
Multi-Class Reorganization. The Master
    
 
                                       12

Trust has similar arrangements for which it pays nominal fees, which will be
terminated upon completion of the Multi-Class Reorganization.

(2) After giving effect to the Multi-Class Reorganization and the Government
    Income Portfolios Reorganization.
 
PURCHASES AND REDEMPTIONS
 
    Shareholders of the Government Income Portfolios who receive shares of
corresponding Classes of the Fully Discretionary Fixed Income Fund in the
Government Income Portfolios Reorganization will be able to purchase and redeem
shares in the Fund in substantially the same manner and subject to substantially
the same conditions as shares in the Portfolios presently are purchased and
redeemed.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
 
   
    The Government Income Portfolios currently pay monthly dividends of net
investment income and annual contributions of net capital gains, if any.
Following the Government Income Portfolios Reorganization, the Fully
Discretionary Fixed Income Fund will declare and pay dividends annually rather
than monthly, and will calculate and make annual distributions of net capital
gains, if any.
    
 
    The Trust has elected to qualify each Government Income Portfolio and the
Fully Discretionary Fixed Income Institutional Portfolio as a regulated
investment company under Subchapter M of the Code, and intends that the Fully
Discretionary Fixed Income Fund will remain so qualified. As a regulated
investment company, the Fully Discretionary Fixed Income Fund will be entitled
to the same benefits and subject to the same tax regulations as the Government
Income Portfolios immediately prior to the Government Income Portfolios
Reorganization.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
 
    The Investment Adviser will execute the portfolio transactions and allocate
the brokerage business of the Fully Discretionary Fixed Income Fund subject to
policies established by the Board of Trustees of the Trust which are
substantially identical to those in effect with respect to the Government Income
master fund immediately prior to the Multi-Class Reorganization.

SHAREHOLDERS' RIGHTS
 
   
    The rights of shareholders of the Classes of the Fully Discretionary Fixed
Income Fund will be identical in all material respects to those of shareholders
of the Government Income Portfolios, except that Class B shares will convert
automatically to Class A shares seven years after purchase. As was the case
before the Multi-Class Reorganization, the shareholders of the Trust will vote
in the aggregate on all matters except those affecting only a particular Fund or
Class, in which case only the shareholders of the affected Fund or Class will
vote. Because the Government Income Portfolios Reorganization will increase the
size of the Fully Discretionary Fixed Income Fund, the voting power of
individual shareholders will be diluted with respect to matters on which
shareholders vote on a Fund-wide basis rather than on an individual Class basis.
    
 
FURTHER INFORMATION ABOUT THE GOVERNMENT INCOME PORTFOLIOS AND THE FULLY
  DISCRETIONARY FIXED INCOME FUND
 
   
    Further information about the Government Income Portfolios and the Fully
Discretionary Fixed Income Institutional Portfolio is contained in their current
prospectuses and statements of additional information, which are incorporated
herein by reference. A copy of the Fully Discretionary Fixed Income Fund's
preliminary prospectus accompanies this Proxy Statement. The Trust will also
provide its most recent annual reports to shareholders with respect to the Fully
Discretionary Fixed Income Institutional Portfolio for the year ended March 31,
1997, and its semiannual report to shareholders for the six months ended
September 30, 1997, upon request. These documents are available without charge
by writing to the Trust at 600 West Broadway, San Diego, California 92101, or by
calling (800) 551-8045.
    
 
   
    The Trust is subject to the information requirements of the Securities
Exchange Act of 1934 and the Investment Company Act of 1940, and as required by
those Acts file reports, proxy statements and other information with the
Securities and Exchange Commission. Such reports, proxy statements and other
information can be inspected and copied at the Public Reference Room maintained
by the SEC at 450 Fifth Street, N.W., Washington, D.C., and at the SEC's
regional offices at 219 South Dearborn Street, Chicago, Illinois and 75 Park
Place, New York, New York. They may also be viewed on the Internet at
www.sec.gov. Copies of such materials can be obtained at prescribed rates from
the Public Reference Branch, Office of Consumer Affairs and Information Services

APPROVAL OF THE BOARD OF TRUSTEES
 
    As discussed above, the Board of Trustees believes that the proposed
Government Income Portfolios Reorganization will be advantageous to the
shareholders of the Portfolios. At their current sizes, the Government Income
Portfolios are too small to operate in a cost effective manner. Management of
the Trust does not foresee any significant increases in the assets of the
Government Income Portfolios or the Government Income master fund in the near
future which would change this situation. Although Nicholas-Applegate Capital
Management has been voluntarily subsidizing the Portfolios' operations, it is
not willing to continue to do so in the future, even after completion of the
Multi-Class Reorganization.
 
   
    Although the Fully Discretionary Fixed Income Fund will have slightly higher
expenses than the Government Income Portfolios, management believes that, as a
result of the Multi-Class Reorganization and the Government Income Portfolios
Reorganization, the combined asset base of the Fund will permit it to spread
reduced expenses over a larger asset base, with reasonable prospects for further
increases in assets and correspondingly lower expenses in the future.
Furthermore, the investment objective of the Fully Discretionary Fixed Income
Fund is similar to that of the Government Income Portfolios, and a substantial
portion of the Fund's portfolio will be comprised of investment-grade
securities. Thus, the Board of Trustees believes that the shareholders of the
Government Income Portfolios should be able to continue to meet their primary
goal of current income from a portfolio comprised principally of high quality
fixed income securities after completion of the Government Income Portfolios
Reorganization.
    
 
                                       14
<PAGE>
    The Board of Trustees believes that the only practical alternative to the
proposed Government Income Portfolios Reorganization would be a taxable
liquidation of the Portfolios, which would not be preferable to the proposed
tax-free reorganization with the Fully Discretionary Fixed Income Fund. However,
if for any reason the proposed Government Income Portfolios Reorganization is
not completed, the Board of Trustees currently believes that its only option
will be such a liquidation.
 
VOTE REQUIRED
 
   
    Approval of the Government Income Portfolios Reorganization requires the
affirmative votes of shareholders holding more than 50% of the outstanding
shares of each of the A, B, C and Qualified Government Income Portfolios. If the
shareholders of all the A, B, C and Qualified Government Income Portfolios do
not approve the proposed Government Income Portfolios Reorganization, or either
the Multi-Class Reorganization or the Government Income Portfolios
Reorganization is not completed for any other reason, then the Board of Trustees
intends to liquidate the Government Income Portfolios.
    
 
   
                       PROPOSAL 4.  ELECTION OF TRUSTEES
    
 
    At the Meeting, shareholders will be asked to elect Trustees of the Trust to
hold office until their successors are elected.
 
   
    The Proxy holders intend to vote for the election of the nominees named
below, all of whom are currently Trustees of the Trust or the Master Trust. All
of the nominees have consented to be named and have indicated their intent to
serve if elected. If any nominee is unavailable for any reason, the Proxy
holders will consult with the Board of Trustees of the Trust in determining how
to vote the shares represented by them.
    
 
    The following table indicates, as to each of the nominees for election as a
Trustee, his or her name, position with the Trust or Master Trust, age,
principal occupation during the past five years, other directorships held in
public companies, and the number of shares of the Trust beneficially owned at
the Record Date. Unless otherwise indicated and subject to applicable community
property and similar laws, each nominee has sole voting and investment power
with respect to the shares of the Trust beneficially owned. Trustees whose names
are followed by an asterisk are "interested persons" of the Trust (as defined by
the Investment Company Act of 1940, as amended).

                      AGREEMENT AND PLAN OF REORGANIZATION
 
   
    This Agreement and Plan of Reorganization (this "Agreement") is made as of
the 1st day of January, 1998, by and among Nicholas-Applegate Mutual Funds, a
Delaware business trust (the "Trust") on behalf of the Government Income A, B, C
and Qualified Portfolio series of the Trust (each a "Government Income
Portfolio" and, collectively, the "Government Income Portfolios"), and the Trust
on behalf of the Fully Discretionary Fixed Income Institutional Portfolio series
of the Trust (the "Fully Discretionary Portfolio").
    
 
                                   BACKGROUND
 
    WHEREAS, the Government Income Portfolios and the Fully Discretionary
Portfolio are series of the Trust, a registered open-end management investment
company that invests all of the assets of each of its series in corresponding
series of Nicholas-Applegate Investment Trust, a Delaware business trust (the
"Master Trust").
 
    WHEREAS, the series of the Master Trust, including the Government Income
Fund series (the "Government Income Master Fund") and the Fully Discretionary
Fixed Income Fund series (the "Fully Discretionary Master Fund"), will dissolve
and distribute their assets in kind to the corresponding series of the Trust,
including the Government Income Portfolios and the Fully Discretionary
Portfolio, respectively, immediately prior to the transactions contemplated by
this Agreement.
 
   
    WHEREAS, the Board of Trustees of the Trust (the "Board of Trustees") has
approved and submitted to the shareholders of all A, B, C and Qualified
portfolios of the Trust other than the Government Income Portfolios (the
"Reorganizing Portfolios") a plan of reorganization (the "Multi-Class
Reorganization") pursuant to which the name of each corresponding Institutional
portfolio of the Trust will be changed to a "Fund" and the current shares of
such portfolio will be designated as Class I shares of the Fund; the assets of
the Reorganizing Portfolios will be transferred to the corresponding Funds in
exchange for Class A, B, C and Qualified shares of the Funds; the shareholders
of the Reorganizing Portfolios will receive (in exchange for their current
shares) shares of corresponding classes of the corresponding Funds; and the
assets of the Funds will be managed pursuant to an Investment Advisory Agreement
between the Trust and Nicholas-Applegate Capital Management (the "Investment
Adviser") rather than by the Master Trust.
    
 
   
    WHEREAS, the parties wish to enter into a plan of reorganization (the
"Plan") which will consist, among other things, of a change in the name of the
Fully Discretionary Fixed Income Institutional Portfolio series of the Trust to
the Fully Discretionary Fixed Income Fund (the "Fully Discretionary Fund");
creation by the Board of Trustees of Class A, B, C and Q shares of the Fully
Discretionary Fund; the transfer of assets of the Government Income A, B, C and
Qualified Portfolios to the Fully Discretionary Fund in exchange for a similar
number of Class A, B, C or Q shares of the Fully Discretionary Fund (the "Fund
Shares"); and distribution by the Government Income Portfolios of the Fund
Shares to their shareholders and dissolution of the Government Income
Portfolios.
    
 
    WHEREAS, the Board of Trustees, including a majority of the Trustees who are
not "interested persons" of the Trust as defined in the Investment Company Act
of 1940, as amended (the "1940 Act"), has determined that the Plan is in the
best interests of the shareholders of each Government Income Portfolio and of
the Fully Discretionary Portfolio and that their interests would not be diluted
as a result of the transactions contemplated thereby.

                                   AGREEMENT
 
    NOW THEREFORE, in consideration of the agreements contained in this
Agreement, the parties agree as follows:
 
                                   ARTICLE 1.
                           MULTIPLE CLASSES OF SHARES
 
    SECTION 1.1  CREATION OF MULTIPLE CLASSES OF SHARES.  Effective on the
Closing Date, as defined in Article IV, the Board of Trustees shall establish
four additional classes of shares of the Fully Discretionary Fund designated
Class A, B, C and Q shares.
 
   
    SECTION 1.2  CHANGE IN NAME OF THE FULLY DISCRETIONARY PORTFOLIO.  Effective
on the Closing Date, the Board of Trustees shall revise the name of the Fully
Discretionary Portfolio to replace the phrase "Institutional Portfolio" with the
phrase "Fund."
    
 
                                   ARTICLE 2.
                       TRANSFER OF ASSETS AND LIABILITIES
 
   
    Subject to the terms and conditions set forth herein, on the Closing Date
the Trust shall cause the Government Income Portfolios to transfer all of their
assets, including all assets received from the Government Income Master Fund, to
the Fully Discretionary Fund, and shall cause the Fully Discretionary Fund to
assume all of the liabilities of the Government Income Portfolios. In exchange
therefor, the Trust shall cause the Fully Discretionary Fund to deliver to each
Government Income Portfolio a number of the Fully Discretionary Fund's Class A,
B, C or Q shares, as applicable, which is equal to (i) the aggregate net asset
value of the corresponding Government Income Portfolio determined at the close
of business on the day prior to the Closing Date, divided by (ii) the net asset
value per share of the respective A, B, C or Q Class of shares of the Fully
Discretionary Fund outstanding as of the Closing Date.
    
 
                                   ARTICLE 3.
                     SHARES OF THE FULLY DISCRETIONARY FUND
 
   
    SECTION 3.1  LIQUIDATION OF A, B, C AND QUALIFIED PORTFOLIOS.  Subject to
the terms and conditions set forth herein, on the Closing Date the Trust shall
liquidate the Government Income Portfolios and shall distribute pro rata to the
shareholders of record of each Government Income Portfolio, determined as of the
Closing Date, the Fund Shares received by such Government Income Portfolio
pursuant to Article 2.
    
 
   
    SECTION 3.2  ISSUANCE OF SHARE CERTIFICATES.  The Trust shall accomplish the
liquidation and distribution provided for herein by opening accounts on the
books of the Fully Discretionary Fund in the names of each Government Income
Portfolio's shareholders and transferring the Fund Shares credited to the
account of the Government Income Portfolio on the books of the Fully
Discretionary Fund. As promptly as practicable after the Closing, each holder of
any outstanding certificate evidencing shares of a Government Income Portfolio
shall be entitled to surrender the same to the Trust's transfer agent and
request in exchange therefor a certificate or certificates representing the
number of shares of beneficial interest of the Class of the Fully Discretionary
Fund into which the shares of beneficial interest theretofore represented by the
certificate or certificates so surrendered shall have been converted.
Certificates for fractional shares of beneficial interests of the Fully
Discretionary Fund shall not be issued, but shall be continued to be carried by
the Fully Discretionary Fund for the open account of such shareholder. Until so
surrendered, each outstanding certificate which, prior to the Closing,
represented shares of beneficial interest of a Government Income Portfolio shall
be deemed for all purposes to evidence ownership of the number of shares of the
Class of shares of beneficial interest of the Fully Discretionary Fund into
which the shares of beneficial interest of such Government Income Portfolio have
been converted.
    
 
                                      A-2
<PAGE>

           basis of such assets to the Government Income Portfolio immediately
           prior to the Reorganization;
 
       (g) The tax basis of Fund Shares received by each shareholder of each
           Government Income Portfolio pursuant to the Reorganization will be
           the same as the tax basis of the Government Income Portfolio shares
           held by such shareholder immediately prior to the Reorganization;
 
       (h) The holding period of the assets of each Government Income Portfolio
           by the Fully Discretionary Fund will include the period during which
           those assets were held by the Government Income Portfolio and the
           Government Income Master Fund; and
 
       (i) The holding period of the Fund Shares to be received by each

                                        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 8 of Registrant's Administration Agreement, filed herewith as
Exhibit 13.1, 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 herewith as Exhibit 7.1,
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 4 of
the Shareholder Service Agreement, filed herewith as Exhibit 13.19, 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 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 and will be governed by the final adjudication of such issue.

               the reoffering prospectus will contain the information called for
