     This Prospectus/Proxy Statement relates to the proposed mergers (the
"Mergers") of the Columbus Circle Investors Core Equity Fund (the "Core Fund")
and the Columbus Circle Investors Mid Cap Equity Fund (the "Mid Cap Fund") (each
an "Acquired Fund"), series of PIMCO Funds: Equity Advisors Series (the
"Trust"), into, respectively, the Growth Fund (the "Growth Fund") and the Target
Fund (the "Target Fund") (each an "Acquiring Fund"), series of the Trust.  The
Acquired Funds and the Acquiring Funds are referred to in this Prospectus/Proxy
Statement as the "Funds."  The Mergers are to be effected through the transfer
of all of the assets of each Acquired Fund to the corresponding Acquiring Fund
in exchange for shares of beneficial interest of the Acquiring Fund (the "Merger
Shares") and the assumption by the Acquiring Fund of all of the liabilities of
the Acquired Fund, followed by the distribution of the Merger Shares to the
shareholders of the Acquired Fund in liquidation of the Acquired Fund.  As a
result of each proposed transaction, each shareholder of the Acquired Fund will
receive in exchange for his or her Acquired Fund shares a number of Acquiring
Fund shares of the same class equal in value at the date of the exchange to the
aggregate value of the shareholder's Acquired Fund shares.

     Because shareholders of the Acquired Funds are being asked to approve
transactions which will result in their holding shares of the Acquiring Funds,
this Proxy Statement also serves as a Prospectus for the Merger Shares of each
Acquiring Fund.  The investment objective of each Acquiring Fund is as follows:

         (1)  The Growth Fund seeks long-term growth of capital, with income as
     an incidental consideration. It invests primarily in common stocks of
     companies that have medium to large equity capitalizations. The Growth Fund
     is a newly organized, diversified series of the Trust which, immediately
     prior and as a condition to the Merger with the Core Fund, will acquire the
     assets and liabilities of and succeed to the

                                      -1-
<PAGE>
 
     business of the PIMCO Advisors Growth Fund (the "PAF Growth Fund"), a
     series of PIMCO Advisors Funds (the "PAF Trust").

         (2)  The Target Fund seeks capital appreciation, with no consideration
     given to income. It invests primarily in common stocks of companies with
     medium equity capitalizations. The Target Fund is a newly organized,
     diversified series of the Trust which, immediately prior and as a condition
     to the merger with the Mid Cap Fund, will acquire the assets and
     liabilities of and succeed to the business of the PIMCO Advisors Target
     Fund (the "PAF Target Fund"), a series of the PAF Trust.

     The Trust, formerly named PIMCO Advisors Institutional Funds, is an open-
end series management investment company, organized as a Massachusetts business
trust in 1990, that currently offers shares of 14 separate funds, not including
the Acquiring Funds.  It is anticipated that, following the Mergers and similar
transactions, the Trust will change its name to "PIMCO Funds: Multi-Manager
Series" to better reflect its management structure.  The PAF Trust is an open-
end series management investment company affiliated with the Trust.

     This Prospectus/Proxy Statement explains concisely what you should know
before investing in each Acquiring Fund.  Please read it and keep it for future
reference.  This Prospectus/Proxy Statement is accompanied by the Prospectus
dated September 15, 1996 of the Trust (the "Trust Prospectus") and the
Prospectus dated February 1, 1996, as supplemented September 18, 1996, of the
PAF Trust (the "PAF Prospectus").  The Trust Prospectus and the PAF Prospectus
contain information about the Acquired Funds and the Acquiring Funds, as well as
the PAF Growth Fund and the PAF Target Fund (the "PAF Funds"), and are
incorporated into this Prospectus/Proxy Statement by reference.

                                    OVERVIEW

 Proposed Transactions

     The transactions described on the first page of this Prospectus/Proxy
Statement are part of an overall restructuring of three of the registered
investment companies (the "PIMCO Mutual Funds") advised by PIMCO Advisors L.P.
("PIMCO Advisors") and its affiliates. The restructuring involves, among other
components, several mergers between Funds in the PIMCO family which are
counterparts of each other in that they are managed by the same investment
adviser in accordance with substantially similar investment objectives and
policies. The result of the restructuring will be a single, more integrated
mutual fund complex, with most PIMCO Mutual Funds offered to both retail and
institutional investors, and with broader exchange privileges for shareholders.

     As part of the restructuring, the Trustees of each of the Trust and the PAF
Trust, both of which are open-end, series investment companies, have approved
transactions involving, for each Acquired Fund and the corresponding PAF Fund,
(i) the reorganization of the PAF Fund from a series of the PAF Trust into a
series of the Trust, i.e. the Acquiring Fund, followed immediately by (ii) the
Merger of the Acquired Fund into the Acquiring Fund.  Each Merger is proposed to
be accomplished pursuant to an Agreement and Plan of Reorganization providing
for the transfer of all of the assets of the Acquired Fund to the Acquiring Fund
in exchange for the assumption by the Acquiring Fund of all of the liabilities
of the Acquired Fund and for shares of the Acquiring Fund.  The completion of
these transactions will result in the liquidation of each Acquired Fund.  Each
Merger is conditioned on the adoption by the PAF Fund of the fee structure
described below under "Expenses" and the reorganization of the PAF Fund as the
Acquiring Fund each having taken place, both of which are subject to approval of
the PAF Fund's shareholders.  A meeting of each PAF Fund's shareholders will be
held on or about December __, 1996 to consider these matters.

     PIMCO Advisors is the investment adviser to both Acquired Funds and to both
Acquiring Funds.  PIMCO Advisors has delegated responsibility for managing each
Fund's portfolio to Columbus Circle Investors ("Columbus Circle"), a subsidiary
partnership of PIMCO Advisors, which serves as sub-adviser to both Acquired
Funds and both Acquiring Funds.  The day-to-day operations of each Acquiring
Fund are handled by the same portfolio management committee at Columbus Circle
as those of the corresponding Acquired Fund. Furthermore, as explained further
below under "Comparison of Investment Objectives, Policies and Restrictions",
each Acquiring Fund is managed in a substantially similar manner to the
corresponding Acquired Fund.

     As a result of each proposed transaction, each Acquired Fund will receive a
number of Institutional Class and Administrative Class shares of the relevant
Acquiring Fund equal in value to the value of the net assets of the Acquired
Fund being transferred and attributable to the Institutional Class and
Administrative Class shares, respectively, of the Acquired Fund.

                                      -4-
<PAGE>
 
Following the transfer, (i) each Institutional Class and Administrative Class
shareholder of the relevant Acquired Fund will receive, on a tax-free basis, a
number of full and fractional Institutional Class or Administrative Class Merger
Shares of the relevant Acquiring Fund equal in value to the aggregate value of
the shareholder's Institutional Class or Administrative Class Acquired Fund
shares, as the case may be, and (ii) the Acquired Funds shall be liquidated.

     Each Fund offers two classes of shares pursuant to this Prospectus:  the
"Institutional Class" and the "Administrative Class," both of which are intended
primarily for institutional investors.  Shares of each Class are offered for
investments of a minimum of [$5 million]. They may also be offered to clients of
Columbus Circle Investors and its affiliates.  Shares of the Institutional Class
are offered primarily for direct investment by investors such as pension and
profit sharing plans, employee benefit trusts, endowments, foundations,
corporations, and other institutions.  Shares of the Administrative Class are
offered primarily through employee benefit plan alliances and pay service fees
to such entities for services they provide to shareholders of that class.
Pension and profit-sharing plans, employee benefit trusts and employee benefit
plan alliances and "wrap account" programs established with broker-dealers of
financial intermediaries may purchase shares of either class only if the plan or
program for which the shares are being acquired will maintain an omnibus or
pooled account for each Fund and will not require a Fund to pay any type of
administrative payment per participant account to any third party.
Administrative Class shares directly or indirectly pay service fees, in the
amount of up to 0.25% per annum, to such entities for services they provide to
shareholders of that class.  Shares of the Institutional and Administrative
Classes of the Acquiring Funds will be offered for sale at the relevant next
determined net asset value for that class with no sales charge, and are not
subject to any contingent deferred sales charge ("CDSC").  Neither the PAF Funds
nor the Acquiring Funds have previously offered Institutional Class or
Administrative Class shares, but the Acquiring Funds will begin offering such
shares to the classes of purchasers listed above at or before the time that the
Mergers are consummated.

     The Trustees of the Trust unanimously recommend that shareholders of each
Acquired Fund approve the Merger for such Fund because it offers shareholders
the opportunity to pursue a substantially similar investment program in a larger
fund, which should offer opportunities for greater diversification of risk;
because the Mergers and the general restructuring of which they are a part will
offer broader exchange privileges; and because the Mergers will immediately
result in Fund operating expenses under the Acquiring Funds' fee structure
described below at lower levels than have historically been experienced.  See
"Background and Reasons for the Proposed Mergers."

                                      -5-

 Operating Expenses

     The Trust's "unified" fee structure will, if approved by the PAF Funds'
shareholders (which approval is a condition to each Merger), apply to the
Acquiring Funds as well as to the Acquired Funds.  Under the unified fee, both
the Acquiring Funds and the Acquired Funds pay an advisory fee, computed as a
percentage of Fund net assets, to their adviser, PIMCO Advisors.  The advisory
fee paid by each Fund covers portfolio management only.  Under the unified fee,
each Fund also pays a single administrative fee, computed as a percentage of
Fund net assets, to its administrator (currently Pacific Investment Management
Company ("PIMCO") and expected to become PIMCO Advisors at or about the time of
the Mergers), which bears the costs of various services reasonably necessary for
the ordinary operation of the Fund such as audit, custodial, portfolio
accounting, legal, transfer agency and printing costs, as well as itself
providing administrative services to the Fund, in exchange for the
administrative fee.  The result is an expense level for each Acquiring Fund that
is precise and predictable under ordinary circumstances.  Furthermore investors
in the Acquired Funds are insulated from price increases in third-party services
and from increased expense ratios arising from a decline in net assets because
the administrator, rather than the Acquiring Fund, bears these risks for a
period of at least one year.  Administrative fee arrangements for the Funds are
discussed further in the "Administrative Arrangements" subsection on page ___.

     For information about the expenses associated with the Mergers, see
"Background and Reasons for the Proposed Mergers."

     As the following tables demonstrate, each Merger would result in
shareholders receiving an immediate and significant reduction in the level of
Fund expenses borne by such shareholders compared to historical periods.  These
tables summarize, for Institutional Class and Administrative Class shares,
expenses (i) that each Acquired Fund incurred in its fiscal year ended June 30,
1996, and (ii) that each Acquiring Fund would have incurred in its most recent
fiscal year after giving effect to the proposed Merger on a pro forma combined
basis as if the Merger had occurred as of the beginning of the Acquiring Fund's
most recent fiscal year.  The tables are provided to help you understand an
investor's share of the operating expenses which each Fund incurs.  The examples
show the estimated cumulative expenses attributable to a hypothetical $1,000
investment in each Acquired Fund, and each Acquiring Fund on a pro forma basis,
over specified periods.

 Federal Income Tax Consequences

          For federal income tax purposes no gain or loss will be recognized by
an Acquired Fund or its shareholders as a result of the Merger, and the tax
basis of the Merger Shares received by each Acquired Fund shareholder will be
the same as the tax basis of the shareholder's Acquired Fund shares.  See
"Information about the Mergers - Federal Income Tax Consequences."

Comparison of Investment Objectives, Policies and Restrictions

          Each Acquiring Fund has investment objectives, policies and
restrictions that are substantially similar to those of the corresponding
Acquired Fund.  The investment objectives, policies and restrictions of the
Acquired Funds and the Acquiring Funds, and certain differences between them,
are summarized below.  For a more detailed description of the investment
techniques used by the Acquired Funds and the Acquiring Funds, please see the
accompanying Trust Prospectus and the PAF Prospectus, respectively.

Core Fund vs. Growth Fund
- -------------------------

          The investment objective of the Growth Fund is long-term growth of
capital, with income as an incidental consideration.  The Fund invests primarily
(normally at least 65% of its assets) in common stocks of companies that have
medium to large equity capitalizations. The Fund may also invest in convertible
securities and, for temporary defensive purposes, in money market instruments.

          The investment objective of the Core Fund is long-term growth of
capital, with income as a secondary objective.  In pursuing these objectives,
the Fund attempts to exceed the total return performance of the S&P 500 over a
reasonable measurement period.  The Fund usually invests at least 65% of its
assets in approximately 40 to 50 common stocks of companies with market
capitalizations in excess of $3 billion.  The Fund may also invest in
convertible securities, preferred stock, warrants subject to certain
limitations, American Depository Receipts ("ADRs"), European Depository Receipts
("EDRs") and Global Depository Receipts ("GDRs").

          Both Funds may invest up to 15% of their net assets in the securities
of foreign issuers traded principally in securities markets outside of the
United States.  However, the Growth Fund may also invest without limit in
securities of foreign issuers that are traded in U.S. securities markets.

          Both Funds may purchase and sell call and put options on securities,
securities indices and foreign currencies; engage in transactions in foreign
currencies, foreign currency options, forward foreign currency contracts,
futures contracts and options on futures contracts; lend their portfolio
securities to brokers, dealers and other financial institutions; purchase
warrants subject to certain restrictions; and enter into repurchase and reverse
repurchase agreements. Each Fund can also invest up to 15% of its net assets in
illiquid securities.  Both Funds may also make short sales "against the box."
 
Mid Cap Fund vs. Target Fund
- ----------------------------

          The investment objective of the Target Fund is capital appreciation,
with no consideration given to income.  The Fund invests primarily (normally at
least 65% of its

                                      -9-
<PAGE>
 
assets) in common stocks of companies with medium equity capitalizations.  The
Fund may also invest in convertible securities and, for temporary defensive
purposes, in money market instruments.

          The investment objective of the Mid Cap Fund is long-term growth of
capital.  In pursuing these objectives, the Fund usually invests at least 65% of
its assets in approximately 40 to 60 common stocks of companies with market
capitalizations between $800 million and $3 billion.  The Fund may also invest
in convertible securities, preferred stock, warrants subject to certain
limitations, ADRs, EDRs and GDRs.

          Both Funds may invest up to 15% of their net assets in the securities
of foreign issuers traded principally in securities markets outside of the
United States.  The Target Fund, unlike the Mid Cap Fund, may also invest
without limit in securities of foreign issuers that are traded in U.S.
securities markets.

          Both Funds may purchase and sell call and put options on securities,
securities indices and on foreign currencies; engage in transactions in foreign
currencies, foreign currency options, forward foreign currency contracts,
futures contracts and options on futures contracts; lend their portfolio
securities to brokers, dealers and other financial institutions; purchase
warrants subject to certain restrictions; and enter into repurchase and reverse
repurchase agreements.  The two Funds can also invest up to 15% of their net
assets in illiquid securities. Both Funds may also make short sales "against the
box."

Comparison of Distribution Policies and Purchase, Exchange and Redemption
Procedures

          Each Acquired Fund and each Acquiring Fund declares and pays dividends
annually and distributes any net realized capital gains annually.

          The Acquired Funds and the Acquiring Funds have substantially the same
procedures for purchasing shares.  Each Fund offers two classes of shares -
Institutional Class and Administrative Class shares. Institutional Class shares
are offered directly to certain types of institutional investors and high net
worth individuals.  Shares of the Administrative Class are offered primarily to
the same types of investors to which the Institutional Class is offered, but use
brokers, retirement plan administrators and other financial intermediaries to
facilitate investment in the Trust.  Administrative Class shares directly or
indirectly pay service fees to these financial intermediaries for the services
they provide to shareholders of that class. Shares of the Institutional Class
and the Administrative Class of the Funds can be purchased at their next-
determined net asset value without sales charge.  The minimum initial investment
for shares of either class is $200,000.  Shares of each class can be obtained
(i) by wiring federal funds to Investors Fiduciary Trust Company (the "Transfer
Agent") or (ii) without wiring federal funds if the proceeds of the investment
are derived from an advisory account maintained by the investor with PIMCO
Advisors or one of its affiliates; from surrender or other payment from an
annuity, insurance, or other contract held by Pacific Mutual Life

                                      -10-
<PAGE>
 
Insurance Company; or from an investment by brokers-dealers, institutional
clients or other financial intermediaries which have established a shareholder
servicing relationship with the Trust on behalf of their customers.

          Shares of each Acquired Fund and each Acquiring Fund can be exchanged
for shares of the same class of any other fund offered by the Trust.  Shares may
also be exchanged for shares of the same class of any fund offered by PIMCO
Funds (the "PIMS Trust"), a series investment company affiliated with the Trust
that currently offers 18 mostly fixed-income mutual funds.

          Redemption procedures for the Acquired Funds and the Acquiring Funds
are substantially identical.  Shares of a Fund may be redeemed without cost at
their net asset value next determined after receipt of the redemption request on
any day the New York Stock Exchange is open.  Shares can be redeemed from either
the Trust or the Transfer Agent, by mail, by telephone or by other means of wire
communication.

                                  RISK FACTORS

          Because each Acquiring Fund shares similar investment objectives and
policies with the corresponding Acquired Fund, as well as the corresponding PAF
Fund, many of the risks of an investment in the Acquiring Fund are substantially
similar to the risks of an investment in the corresponding Acquired Fund or the
corresponding PAF Fund.  Certain risks associated with an investment in the
Acquiring Funds are summarized below.  A more detailed description of certain of
the risks associated with an investment in the Acquiring Funds may be found by
referring to the risks associated with an investment in the PAF Funds and the
Acquired Funds which are set forth, respectively, in the accompanying PAF
Prospectus under the caption "Description and Risks of Fund Investments" and the
accompanying Trust Prospectus under the caption "Characteristics and Risks of
Securities and Investment Techniques."

          The values of all securities and other instruments held by the
Acquiring Funds vary from time to time in response to a wide variety of market
factors.  Consequently, the net asset value per share of the Acquiring Funds
will vary.  The net asset value per share of an Acquiring Fund may be less at
the time of redemption than it was at the time of investment.

          It is the policy of the Acquired Funds to be as fully invested as
practicable in equity securities at all times.  This policy precludes the
Acquired Funds from investing in money market securities as a defensive
investment posture (unlike the Acquiring Funds, which may invest defensively
when conditions warrant), although the Acquired Funds can invest in such
securities to provide for payment of expenses and to meet redemption requests.
Accordingly, investors in the Acquiring Funds may be exposed to less risk
associated with general declines in the prices of equity securities if or when
the Acquiring Fund invests defensively.

                                      -11-
<PAGE>
 
Conversely, investors in the Acquiring Funds may not participate fully in
general increases in the prices of equity securities when a Fund has taken a
defensive position.

          Companies with Small and Medium Equity Capitalizations. The Target
Fund, like the Mid Cap Fund, may invest in common stock of companies with small
and medium capitalizations. Some of the risks associated with such investments
are greater sensitivity to market movements than larger, more seasoned and
established companies; limited product lines, markets or financial resources;
and potential dependence upon a limited management group.  The Growth Fund, like
the Core Fund, may invest in securities of companies with medium capitalization.
These securities share some of the risks associated with those of small
capitalization companies, but tend to be more liquid and less volatile than
those of small equity capitalization issuers.

          Foreign Investments. The Acquiring Funds, like the Acquired Funds, may
invest in securities of foreign issuers, which may be subject to additional risk
factors, including foreign currency and political risks, not applicable to
securities of U.S. issuers.  Some of the risks of investing in foreign
securities include adverse changes in foreign currency exchange rates and
restrictions, liquidity risks, tax liability, and risks of adverse political and
economic developments.

          Other Foreign Currency Transactions.  The Acquiring Funds, like the
Acquired Funds, are subject to the risk in foreign currency transactions that
currency exchange rates may fluctuate significantly and unpredictably over a
short period of time.

          Derivative Instruments.  The Acquiring Funds, like the Acquired Funds,
may use derivative instruments, consisting of futures, options, options on
futures and swap contracts, for hedging purposes or as part of their investment
strategies.  Use of these instruments may involve certain costs and risks,
including the risk that the Fund could not close out a position when it would be
most advantageous to do so due to an illiquid market, the risk of an imperfect
correlation between the value of the securities being hedged and the value of
the particular derivative instrument, the risk of bankruptcy or default of
counterparties, and the risk that unexpected changes in interest rates or other
market movements may adversely affect the value of the Fund's investments in
particular derivative instruments.

          Loans of Portfolio Securities.  The Acquiring Funds and the Acquired
Funds may incur similar risks in lending their securities to broker-dealers if
they exercise their right to lend securities.  These risks include the risk of
loss of rights in the collateral or delay in recovery of the collateral if the
borrower fails financially.

          Short Sales.  Short sales expose the Funds to the risk that they will
be required to purchase securities to cover their short positions at a time when
the securities have appreciated in value, thus resulting in a loss to a Fund.

                                      -12-
<PAGE>
 
          Forward Commitments, When-Issued and Delayed Delivery Transactions.
Engaging in delayed delivery, when-issued and forward commitment transactions
pose similar risks for both the Acquiring Funds and the Acquired Funds.  These
transactions involve the risk of loss if the value of the securities declines
prior to the settlement date, which risk is in addition to the risk of decline
in the value of the Fund's other assets.  In addition, no income accrues to the
purchaser of the securities prior to delivery.

          Repurchase Agreements.  Investing in repurchase agreements subjects
the Acquiring Funds, like the Acquired Funds, to the risk that the default or
bankruptcy of the seller of the repurchase agreement could subject the Fund to
expenses, delays and risk of loss on the securities.  The Acquiring and Acquired
Funds, however, currently treat their investments in repurchase agreements
maturing in more than seven days as illiquid securities and limit those
investments accordingly.  See "Illiquid Securities" below.

          Reverse Repurchase Agreements and Other Borrowings.  Reverse
repurchase agreements and borrowings subject the Acquiring Funds and the
Acquired Funds to the risk that changes in the value of the Fund's portfolio
securities may amplify changes in the Fund's net asset value per share and also
may cause the Fund to liquidate portfolio positions when it would not be
advantageous to do so.  Each Acquired Fund subjects reverse repurchase
agreements to the Fund's overall borrowing limits.

          Illiquid Securities.  The Acquiring Funds and the Acquired Funds share
similar risks from investing in illiquid securities - specifically, higher
transaction costs.  The Funds limit their investment in illiquid securities to
no more than 15% of their net assets.

                        SPECIAL MEETING OF SHAREHOLDERS

          This Prospectus/Proxy Statement is furnished in connection with a
Special Meeting of Shareholders to be held on December __, 1996 or at such later
time made necessary by adjournment (the "Meeting") and the solicitation of
proxies by and on behalf of the Trustees of the Trust for use at the Meeting.
The Meeting is being held to consider the proposed Mergers of each Acquired Fund
with the corresponding Acquiring Fund by the transfer of all of the Acquired
Fund's assets and liabilities to the Acquiring Fund.  This Prospectus/Proxy
Statement and the enclosed form of proxy are being mailed to shareholders on or
about October __, 1996.

          The Trustees of the Trust know of no matters other than those set
forth herein to be brought before the Meeting.  If, however, any other matters
properly come before the Meeting, it is the Trustees' intention that proxies
will be voted on such matters in accordance with the judgment of the persons
named in the enclosed form of proxy.

                                 PROPOSALS 1 AND 2:

              APPROVAL OR DISAPPROVAL OF AGREEMENT AND PLAN OF   
                                REORGANIZATION

          The shareholders of the Core Fund are being asked to approve or
disapprove a Merger between the Core Fund and the Growth Fund (Proposal 1); and
the shareholders of the Mid Cap Fund are being asked to approve or disapprove a
Merger between the Mid Cap Fund and the Target Fund (Proposal 2).  Each Merger
is proposed to take place pursuant to an Agreement and Plan of Reorganization
between the Acquired Fund and the Acquiring Fund, dated as of November __, 1996
(the "Agreement"), each of which is in the form attached to this
Prospectus/Proxy Statement as Appendix A.

          Each Agreement provides, among other things, for the transfer of all
of the assets of the Acquired Fund to the Acquiring Fund in exchange for (i) the
assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund
and (ii) the issuance to the Acquired Fund of the Institutional Class and
Administrative Class Merger Shares, the number of which will be calculated based
on the value of the net assets attributable to the Institutional Class and
Administrative Class shares, respectively, of the Acquired Fund acquired by the
Acquiring Fund and the net asset value per Institutional Class and
Administrative Class share of the Acquiring Fund, all as more fully described
below under "Information About the Reorganization."

          After receipt of the Merger Shares, the Acquired Fund will cause the
Institutional Class Merger Shares to be distributed to its Institutional Class
shareholders and the Administrative Class Merger Shares to be distributed to its
Administrative Class shareholders, in complete liquidation of the Acquired Fund.
Each shareholder of the Acquired Fund will receive a number of full and
fractional Institutional Class or Administrative Class Merger Shares equal in
value at the date of the exchange to the aggregate value of the shareholder's
Institutional Class or Administrative Class Acquired Fund shares, as the case
may be.

          Trustees' Recommendations.  The Trustees of the Trust have voted
unanimously to approve each proposed Merger and to recommend that shareholders
of each Acquired Fund also approve the Merger for such Fund.

          Required Shareholder Vote.  Approval of each proposed Merger for each
Acquired Fund will require the affirmative vote of the lesser of (A) 67% or more
of the Institutional Class and Administrative Class shares of the relevant
Acquired Fund present or represented by proxy at the Meeting, if the holders of
more than 50% of the outstanding Institutional Class and Administrative Class
shares are present or represented by proxy at the Meeting, or (B) more than 50%
of the outstanding Institutional Class and Administrative Class shares of the
relevant Acquired Fund.

                                      -14-
<PAGE>
 
          A shareholder of an Acquired Fund objecting to the proposed Merger is
not entitled under either Massachusetts law or the Trust's Agreement and
Declaration of Trust (the "Declaration of Trust") to demand payment for and an
appraisal of his, her or its Acquired Fund shares if the Merger is consummated
over his, her or its objection.  Shareholders may, however, redeem their shares
at any time prior to the Merger and if the Merger is consummated, shareholders
will still be free at any time to redeem their merger Shares, for cash at net
asset value at the time of such redemption, or to exchange their Merger Shares
for shares of the same class of certain other funds offered by the Trust or
PIMCO Funds, at net asset value at the time of such exchange.  See "Exchange
Privilege" in the Trust Prospectus.

          Each proposed Merger is subject to both the approval of the
shareholders of the relevant Acquired Fund and the approval by the shareholders
of the corresponding PAF Fund of both (i) the reorganization of the PAF Fund
into the corresponding Acquiring Fund, and (ii) the Trust's "unified fee"
structure, both of which are conditions to the consummation of each Merger.  A
meeting of shareholders of the PAF Funds will be held on or about December __,
1996 to vote on the approval of the reorganization of the PAF Funds as the
Acquiring Funds and the approval of the unified fee structure.  In the event
that such reorganization or unified fee structure is not approved by the
shareholders of a PAF Fund or a Merger is not approved by the shareholders of
the Acquired Fund, the Acquired Fund will continue to be managed as a separate
series of the Trust in accordance with its current investment objective and
policies, and the Trust's Trustees may consider such alternatives as may be in
the best interests of shareholders.

Background and Reasons for the Proposed Mergers

          The Trustees of the Trust, including the Trustees who are not
"interested persons" of the Trust (the "Independent Trustees"), have determined
that each Merger would be in the best interests of the relevant Acquired Fund
and the corresponding Acquiring Fund, and that the interests of the Acquired
Fund's shareholders and the Acquiring Fund's shareholders (including the PAF
Fund shareholders who become Acquiring Fund shareholders as a result of the
reorganization of the PAF Fund as the Acquiring Fund) would not be diluted as a
result of effecting the Merger.  The Trustees have unanimously approved each
proposed Merger and have recommended its approval by shareholders.  In addition
to the reasons for recommending the Mergers described below, the Trustees took
into account the fact that the Acquired Funds (and, indirectly, the Acquiring
Funds) will be bearing a portion of the expenses associated with the Mergers,
including those described under "Information about the Mergers."  The Trustees
also considered the unrealized capital appreciation in each Acquiring Fund and
the unrealized capital appreciation in the corresponding Acquired Fund, in each
case as a percentage of the Fund's total net assets.  Those percentages as of
June 30, 1996 were as follows:

          The principal reasons why the Trustees are recommending the Mergers,
and the overall restructuring of the PIMCO Mutual Funds of which the Mergers are
a part, are as follows:

          (i)   Economies of scale at Fund level.  The Trustees have determined
that it is in the best interests of each Acquired Fund's shareholders to combine
the Acquired Fund with the corresponding Acquiring Fund (which will have
succeeded to the assets of the PAF Fund) in order to increase the asset base
over which the Acquired Fund's expenses will be spread, which, in part has
allowed the Trustees to approve agreements that provide total fees at more
favorable rates.  As described more fully in the Overview under "Operating
Expenses," fees for each Acquired Fund will decline immediately following the
Mergers.  Of course, there can be no assurance that the Mergers will continue to
result in savings in operating expenses to shareholders.

          (ii)  Unified Fee Structure.  Pursuant to the Trust's unified fee
structure, Acquired Fund shareholders will continue to enjoy the benefits of a
level of Fund expenses that is, under ordinary circumstances, precise and
predictable.  Acquired Fund shareholders will also continue to be insulated from
price increases in third-party services and from associated increased expense
ratios arising from a decline in net assets.  However, there can be no assurance
that the Mergers will continue to result in savings in operating expenses to
shareholders.  Information on each Fund's operating expenses is set out above in
the Overview under "Expenses."

          (iii)  Appropriate investment objectives, diversification, etc.  The
investment objective, policies, and restrictions of each Acquiring Fund are
substantially similar to those of the corresponding Acquired Fund, and the
Trustees believe that an investment in shares of the Acquiring Fund will provide
shareholders with an investment opportunity comparable to that currently
afforded by the Acquired Fund, with the potential for reduced investment risk
because of the opportunities for additional diversification of portfolio
investments through increased Fund assets.

          (iv)  Continued investment in a mutual fund without recognition of
gain or loss for federal income tax purposes.  The proposed reorganization will
permit Acquired Fund shareholders to keep their investment in an open-end mutual
fund, without recognition of gain

                                      -16-
<PAGE>
 
or loss for federal income tax purposes.  If the Acquired Funds were to
liquidate and shareholders were to receive the net asset value of their shares
in liquidating distributions, gain or loss would be recognized for federal
income tax purposes.

          (v)  Larger, more integrated fund complex.  The restructuring of the
PIMCO Mutual Funds (which is subject to satisfaction of a number of conditions,
including shareholder approval of the Mergers) should reduce confusion for
shareholders between funds with similar names and/or investment objectives.  It
will also give shareholders broader exchange privileges among Funds.  The
restructuring may also allow the expansion of institutional and retail
distribution channels.

Information About the Mergers

          Agreement and Plan of Reorganization.  Each proposed Agreement and
Plan of Reorganization provides that the relevant Acquiring Fund will acquire
all of the assets of the corresponding Acquired Fund in exchange for the
assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund
and for the issuance of the Institutional Class and Administrative Class Merger
Shares, all as of the Exchange Date (defined in each Agreement to be January __,
1997 or such other date as may be agreed upon by the Acquiring Fund and the
Acquired Fund).  The following discussion of the Agreements is qualified in its
entirety by the full text of each Agreement, the form of which is attached as
Appendix A to this Prospectus/Proxy Statement.

          Each Acquired Fund will sell all of its assets to the corresponding
Acquiring Fund, and, in exchange, the Acquiring Fund will assume all of the
liabilities of the Acquired Fund and deliver to the Acquired Fund  (i) a number
of full and fractional Institutional Class Merger Shares having an aggregate net
asset value equal to the value of the assets of the Acquired Fund attributable
to its Institutional Class shares, less the value of the liabilities of the
Acquired Fund assumed by the Acquiring Fund attributable to the Institutional
Class shares of the Acquired Fund, and (ii) a number of full and fractional
Administrative Class Merger Shares having a net asset value equal to the value
of assets of the Acquired Fund attributable to its Administrative Class shares,
less the value of the liabilities of the Acquired Fund assumed by the Acquiring
Fund attributable to the Administrative Class shares of the Acquired Fund.

          Immediately following the Exchange Date, each Acquired Fund will
distribute pro rata to its shareholders of record as of the close of business on
the Exchange Date the full and fractional Merger Shares received by the Acquired
Fund, with Institutional Class Merger Shares being distributed to holders of
Institutional Class shares of the Acquired Fund and Administrative Class Merger
Shares being distributed to holders of Administrative Class shares of the
Acquired Fund.  As a result of the proposed transaction, each holder of
Institutional Class and Administrative Class shares of the Acquired Fund will
receive a number of Institutional Class and Administrative Class Merger Shares
equal in aggregate value at the Exchange Date to the value of the Institutional
Class and Administrative Class shares,

                                      -17-
<PAGE>
 
respectively, of the Acquired Fund held by the shareholder.  This distribution
will be accomplished by the establishment of accounts on the share records of
the corresponding Acquiring Fund in the names of the Acquired Fund shareholders,
each account representing the respective number of full and fractional
Institutional Class or Administrative Class Merger Shares due such shareholder.
New certificates for Merger Shares will not be issued. Shareholders of the
Acquired Funds holding certificates for shares will be sent instructions on how
they will be able to exchange those certificates for certificates representing
shares of the Acquiring Funds.

          The consummation of each Merger is subject to the conditions set forth
in the Agreement, any of which may be waived, which conditions include, among
others, the approval of the PFEAS Shareholders of (a) a Second Amended and
Restated Declaration of Trust, as described below in "Declaration of Trust", and
(b) the election of the Trustees of the PAF Trust to the Trust's Board of
Trustees.  The Agreement may be terminated and the Merger abandoned at any time,
before or after approval by the shareholders of each Fund, prior to the Exchange
Date, by mutual consent of the relevant Funds or, if any condition set forth in
the Agreement has not been fulfilled and has not been waived by the party
entitled to its benefits, by such party.

          All legal and accounting fees and expenses, printing and other fees
and expenses (other than portfolio transfer taxes (if any), brokerage and other
similar expenses, all of which will be borne by the relevant Fund) incurred in
connection with the consummation of the transactions contemplated by the
Agreement will be allocated in accordance with the following:  First, the costs
of the overall restructuring of the PIMCO Mutual Funds referred to in the
Overview under " Proposed Transactions," including the costs of the Mergers and
this Prospectus/Proxy Statement, are being preliminarily allocated on a basis
approved by the Trustees, including the Independent Trustees, of the PFEAS
Trust.  PIMCO Advisors will bear any and all expenses preliminarily allocated to
the Acquiring Fund and PIMCO Advisors will also bear any and all expenses
allocated to the Acquired Fund to the extent that they would otherwise exceed
the respective expense caps (the "Relevant Expense Caps") set forth below.   The
Acquired Funds have agreed to pay the expenses preliminarily allocated to them
but not, however, in an amount exceeding the Relevant Expense Caps.  The
Relevant Expense Caps represent a percentage (approximately 50%) of the
projected aggregate savings for shareholders of the Acquired Funds for the first
year following the Mergers.  The currently estimated expenses to be borne by the
Funds and the Relevant Expense Caps are as follows:

Notwithstanding any of the foregoing, expenses will in any event be paid by the
party directly incurring such expenses if and to the extent that the payment by
any other party of such

                                      -18-

expenses would result in the disqualification of the first party as a "regulated
investment company" within the meaning of Section 851 of the Code.

          Description of the Merger Shares.  Full and fractional Merger Shares
will be issued to each Acquired Fund's shareholders in accordance with the
procedure under the Agreement as described above.  The Merger Shares are
Institutional Class and Administrative Class shares of the Acquiring Fund, which
have identical characteristics to those of the corresponding class of Acquired
Fund shares with respect to sales charges, administrative fees and service fees.
Institutional Class and Administrative Class shares are sold at net asset value,
without a sales charge, and are not subject to any CDSC or 12b-1 fees.  The
Institutional and Administrative classes pay an administrative fee at the annual
rate of up to 0.25% of its average daily net assets.  Administrative Class
shares pay in addition a service fee at the annual rate of 0.25% of its average
daily net assets.  These arrangements are identical to those currently in effect
for the Acquired Funds, as described in the Trust Prospectus at pages [_____].

          Administrative Arrangements.  PIMCO currently serves (and PIMCO
Advisors from and after the Mergers will serve) as administrator to the
Acquiring Funds pursuant to an administration agreement.  The administrator will
provide administrative services to the Acquiring Funds, which includes clerical
help and accounting, bookkeeping, internal audit services, and certain other
services required by the Acquiring Funds, preparation of reports to the
Acquiring Funds' shareholders and regulatory filings.  In addition, the
administrator, at its own expense, will arrange for the provision of legal,
audit, custody, portfolio accounting, transfer agency and other ordinary
services for the Acquiring Funds, and will be responsible for the costs of
registration of the Acquiring Funds' shares and the printing of prospectuses and
shareholder reports for current shareholders.  For such services, each Acquiring
Fund pays the administrator an administrative fee at the annual rate of 0.25% of
the average daily net assets attributable to each Fund's Institutional and
Administrative Class shares.

          Certain expenses of the Acquiring Funds are not borne by the
administrator.  The Acquiring Funds are responsible for the following expenses:
(i) salaries and other compensation of any of the Trust's executive officers and
employees who are not officers, directors, stockholders, or employees of PIMCO
Advisors, PIMCO, or their subsidiaries or affiliates; (ii) taxes and
governmental fees; (iii) brokerage fees and commissions and other portfolio
transaction expenses; (iv) the costs of borrowing money, including interest
expenses; (v) fees and expenses of the Trustees who are not "interested persons"
of the Trust, the Adviser, PIMCO, the sub-advisers ("Portfolio Managers") to the
funds in the Trust, and any counsel retained exclusively for their benefit; (vi)
extraordinary expenses, including costs of litigation and indemnification
expenses; (vii) expenses which are capitalized in accordance with generally
accepted accounting principles; and (viii) any expenses allocated or allocable
to a specific class of shares, which include distribution and/or service fees
payable with respect to Institutional and Administrative Class shares and may
include certain other expenses as permitted by the Trust's Amended and Restated
Multi-Class Plan adopted pursuant to Rule

                                      -19-
<PAGE>
 
18f-3 under the Investment Company Act of 1940, as amended (the "1940 Act") and
subject to review and approval by the Trustees.

          Declaration of Trust.  Each of the Merger Shares will be fully paid
and nonassessable by the Trust when issued, will be transferable without
restriction, and will have no preemptive or conversion rights.  The Trust's
Declaration of Trust permits the Trust to divide its shares, without shareholder
approval, into two or more series of shares representing separate investment
portfolios and to further divide any such series, without shareholder approval,
into two or more classes of shares having such preferences and special or
relative rights and privileges as the Trustees may determine.  Each Acquiring
Fund's shares are currently divided into five classes:  the Institutional Class,
the Administrative Class, Class A, Class B and Class C.

          Under Massachusetts law, shareholders of a Massachusetts business
trust could, under certain circumstances, be held personally liable for the
obligations of the trust.  However, the Declaration of Trust disclaims
shareholder liability for acts or obligations of the Trust and/or the Acquiring
Funds and requires that notice of such disclaimer be given in each agreement,
undertaking, or obligation entered into or executed by the Trust, the Acquiring
Funds or the Trustees.  The Declaration of Trust provides for indemnification
out of Acquiring Fund property for all loss and expense of any shareholder held
personally liable for the obligations of the Acquiring Fund.  Thus, the risk of
a shareholder's incurring financial loss from shareholder liability is limited
to circumstances in which the Acquiring Fund would be unable to meet its
obligations.  The likelihood of such a circumstance is considered remote.  The
shareholders of the Acquired Fund are currently subject to this same risk of
shareholder liability, under Massachusetts law and the Declaration of Trust.

          As part of the overall restructuring of the PIMCO Mutual Funds (of
which the proposed Mergers are a part), the Trust's Trustees have adopted and
have proposed to the Trust's shareholders (including shareholders of the
Acquired Funds) that they approve, a Second Amended and Restated Declaration of
Trust (the "Proposed Declaration of Trust"), which would take the place of the
Declaration of Trust.  In all material respects, the provisions of the Trust's
Declaration of Trust described in the preceding paragraph are the same as the
corresponding provisions in the Proposed Declaration of Trust.  If the Proposed
Declaration of Trust is approved by the Trust's shareholders, it will become
effective on or about the time of the effectiveness of the proposed Merger.  The
Trust's shareholders will vote on the approval of the Proposed Declaration of
Trust on or about December __, 1996.  You should have received, or will soon
receive, a Proxy Statement in respect of this proposal.  Please refer to such
Proxy Statement for more information about, and a detailed comparison between,
the Declaration of Trust and the Proposed Declaration of Trust.  Approval of the
Proposed Declaration of Trust is a condition to the consummation of the proposed
Mergers.  Thus, the Merger Shares may be governed by the provisions of either
the Declaration of Trust or the Proposed Declaration of Trust, depending on
whether the Proposed Declaration of Trust is approved.

          Federal income tax consequences.  As a condition to each Acquired
Fund's obligation to consummate the Merger, the Acquired Fund will receive an
opinion from Ropes & Gray, special counsel to the Trust, to the effect that, on
the basis of the existing provisions of the Internal Revenue Code of 1986, as
amended (the "Code"), current administrative rules and court decisions, for
federal income tax purposes: (i) under Section 361 of the Code, no gain or loss
will be recognized by the Acquired Fund as a result of the reorganization; (ii)
under Section 354 of the Code, no gain or loss will be recognized by
shareholders of the Acquired Fund on the distribution of Merger Shares to them
in exchange for their shares of the Acquired Fund; (iii) under Section 358 of
the Code, the tax basis of the Merger Shares that the Acquired Fund's
shareholders receive in place of their Acquired Fund shares will be the same as
the basis of the Acquired Fund shares; and (iv) under Section 1223(1) of the
Code, a shareholder's holding period for the Merger Shares received pursuant to
the Agreement will be determined by including the holding period for the
Acquired Fund shares exchanged for the Merger Shares, provided that the
shareholder held the Acquired Fund shares as a capital asset.  The opinion will
be based on certain factual certifications made by officers of the Trust and
will also be based on customary assumptions.

          Prior to the date of the Exchange Date, each Acquired Fund will
declare a distribution to shareholders which, together with all previous
distributions, will have the effect of distributing to shareholders all of its
investment company taxable income (computed without regard to the deduction for
dividends paid) and net realized capital gains, if any, through the Exchange
Date.

          Capitalization.  The following tables show the capitalization of each
PAF Fund, each Acquired Fund and each Acquiring Fund as of June 30, 1996 and on
a pro forma basis as of that date, giving effect to (i) the proposed
reorganization of the PAF Fund as the Acquiring Fund, and (ii) the proposed
acquisition by the Acquiring Fund of the assets and liabilities of the Acquired
Fund at net asset value:

          Pro forma financial statements of the Funds as of and for the fiscal
year ended June 30, 1996 are included in the Merger Statement of Additional
Information.  Because each Agreement provides that the Acquiring Fund will be
the surviving Fund following the reorganization and because the Acquiring Fund's
investment objective and policies will remain unchanged, the pro forma financial
statements reflect the transfer of the assets and liabilities of the Acquired
Fund to the Acquiring Fund as contemplated by the Agreement.  Because the assets
of the Core Fund and the Mid Cap Fund each represent less than 10% of the assets
of their respective Acquiring Funds, pro forma financial statements for the
Acquiring Funds are not provided.

  INFORMATION ABOUT THE ACQUIRED FUNDS AND THE ACQUIRING FUNDS

          Other information regarding the Acquired Funds, including information
with respect to the Acquired Funds' investment objectives, policies and
restrictions may be found in the enclosed Trust Prospectus and in the Merger
Statement of Additional Information, the Trust Statement of Additional
Information and the Trust Annual Report, which are available upon request by
calling 1-800-927-4648.

          The information in the Trust Prospectus regarding each Acquired Fund
(not including the information regarding such Fund's financial history and past
performance) is equally applicable to the corresponding Acquiring Fund, as
supplemented below:

          PIMCO Advisors will serve as adviser to each Acquiring Fund (in
addition to all other funds in the Trust) pursuant to an investment advisory
agreement similar to the agreement described in the Trust Prospectus on page(s)
[___].  PIMCO Advisors will retain Columbus Circle as sub-adviser of each
Acquiring Fund.  The investment decisions made by Columbus Circle with respect
to each Acquiring Fund will be made by a committee rather than by a single
person acting as portfolio manager.  No person is primarily responsible for
making recommendations to that committee.  For providing investment advisory
services to the Growth Fund and the Target Fund, PIMCO Advisors will receive
monthly fees at the annual rates of 0.50% and 0.55%, respectively, of the Fund's
average daily net assets.  Pursuant to the Portfolio Management Agreement
between PIMCO Advisors and Columbus Circle, PIMCO Advisors (not the Funds) will
pay Columbus Circle a fee at the annual rates of 0.34% and 0.36%, respectively,
of the Growth Fund's and the Target Fund's average daily net assets.

          Certain differences between each Acquiring Fund and the corresponding
Acquired Fund with respect to investment policies, restrictions, risks are
discussed in this Prospectus/Proxy Statement in the Overview under the caption
"Comparison of Investment Objectives, Policies and Restrictions" and the Risk
Factors above.

          Proxy materials, reports, proxy and information statements and other
information filed by the Trust with respect to the Acquiring and Acquired Funds

                              VOTING INFORMATION

          Record date, quorum and method of tabulation.  Shareholders of record
of each Acquired Fund at the close of business on October __, 1996 (the "Record
Date") will be entitled to notice of and to vote at the Meeting or any
adjournment thereof.  The holders of more than 30% of each of the Institutional
Class and Administrative Class shares of each Acquired Fund outstanding at the
close of business on the Record Date present in person or represented by proxy
will constitute a quorum for the Meeting with respect to that Fund. Shareholders
are entitled to one vote for each share held, with fractional shares voting
proportionally.  Shareholders of each Acquired Fund will vote only on the
approval or disapproval of that Fund's Merger.

          Votes cast by proxy or in person at the Meeting will be counted by
persons appointed by the Trust as tellers for the Meeting.  The tellers will
count the total number of votes cast "for" approval of the proposal for purposes
of determining whether sufficient affirmative votes have been cast.  The tellers
will count shares represented by proxies that reflect abstentions and "broker
non-votes" (i.e., shares held by brokers or nominees as to which (i)
instructions have not been received from the beneficial owners or the persons
entitled to vote and (ii) the broker or nominee does not have the discretionary
voting power on a particular matter) as


                                     -25-
<PAGE>
 
shares that are present and entitled to vote on the matter for purposes of
determining the presence of a quorum.  So long as a quorum is present,
abstentions and broker non-votes have the effect of negative votes on the
proposal.

          Shares outstanding and beneficial ownership.  As of the Record Date,
as shown on the books of the Trust, there were issued and outstanding the
following number of shares of beneficial interest of each class of each Acquired
Fund:

                              Institutional Class       Administrative Class
                              -------------------       --------------------

          Core Fund
          Mid Cap Fund

          As of the Record Date, the officers and Trustees of the Trust as a
group beneficially owned [less than 1%] of the outstanding shares of each class
of each Acquired Fund.  As of the Record Date, to the best of the knowledge of
the Trust, the following persons owned beneficially 5% or more of the
outstanding shares of the indicated classes of the Acquired Funds:

          [insert list of 5% shareholders and pro forma ownership of the 5%
shareholders following Mergers]

          As of the Record Date, no shares of either of the Acquiring Funds were
issued and outstanding.

          Solicitation of proxies.  Solicitation of proxies by personal
interview, mail, and telephone, may be made by officers and Trustees of the
Trust and employees of the Adviser and its affiliates.  In addition, the firm of
____________ has been retained to assist in the solicitation of proxies.  The
costs for solicitation of proxies, like the other costs associated with the
general restructuring of the PIMCO Mutual Funds, will be only partially borne by
the Funds.  See "Information About the Mergers."

          Revocation of proxies.  Any shareholder giving a proxy has the power
to revoke it by mail (addressed to the Trust's Secretary at the principal office
of the Trust at 840 Newport Center Drive, Suite 360, Newport Beach, California
92660) or in person at the Meeting, by executing a superseding proxy, or by
submitting a notice of revocation to the Secretary of the Trust.  All properly
executed proxies received in time for the Meeting will be voted as specified in
the proxy, or, if no specification is made, FOR the proposal (set forth in
Proposals 1 and 2 of the Notice of Meeting) to implement the Merger with respect
to the relevant Acquired Fund.

          Adjournment.  If sufficient votes in favor of either proposal are not
received by the time scheduled for the Meeting, the persons named as proxies may
propose one or more


                                     -26-
<PAGE>
 
adjournments of the Meeting to permit further solicitation of proxies.  Any
adjournment will require the affirmative vote of a plurality of the votes cast
on the question in person or by proxy at the session of the Meeting to be
adjourned.  If the Meeting is adjourned only with respect to one proposal, any
other proposal may still be acted upon by the shareholders.  The persons named
as proxies will vote in favor of such adjournment those proxies which they are
entitled to vote in favor of the proposal.  They will vote against any such
adjournment those proxies required to be voted against the proposal.  The
Acquired Funds will pay the costs of any additional solicitation and of any
adjourned session.

                                 APPENDIX A


                     AGREEMENT AND PLAN OF REORGANIZATION
                         (PFEAS Growth & Target Funds)

          This Agreement and Plan of Reorganization (the "Agreement") is made as
of November __, 1996 in ______, ______, by and between the [Columbus Circle
Investors Core Equity][Columbus Circle Investors Mid-Cap Equity] Fund (the
"Acquired Fund"), a separate series of PIMCO Funds: Equity Advisors Series, a
Massachusetts business trust (the "PFEAS Trust"), and the [Growth][Target] Fund
(the "Acquiring Fund"), a separate series of the PFEAS Trust.

                             PLAN OF REORGANIZATION
                             ----------------------

          (a)  Pursuant to an Agreement and Plan of Reorganization dated as of
November __, 1996 by and between the PFEAS Trust, on behalf of the Acquiring
Fund, and PIMCO Advisors Funds, a Massachusetts business trust, on behalf of its
____________ Fund series (the "PAF Fund"), the Acquiring Fund will, subject to
the conditions set forth in such Agreement and Plan of Reorganization, acquire
substantially all of the assets and properties of the PAF Fund in exchange for
which the Acquiring Fund will assume all of the liabilities of the PAF Fund and
will deliver to the PAF Fund Class A, Class B and Class C shares of beneficial
interest of the Acquiring Fund having the same aggregate net asset value as the
outstanding Class A, Class B and Class C shares of the PAF Fund.  In connection
with the foregoing, the PAF Fund will distribute its shares in complete
liquidation of the PAF Fund. (The foregoing transaction is hereafter referred to
as the "PAF Reorganization".)

          (b)  Immediately following the PAF Reorganization, the Acquired Fund
will sell, assign, convey, transfer and deliver to the Acquiring Fund on the
Exchange Date (as defined in Section 6) all of its properties and assets.  In
consideration therefor, the Acquiring Fund shall, on the Exchange Date, assume
all of the liabilities of the Acquired Fund existing at the Valuation Time and
deliver to the Acquired Fund (i) a number of full and fractional Institutional
Class shares of beneficial interest of the Acquiring Fund (the "Institutional
Class Merger Shares") having an aggregate net asset value equal to the value of
the assets of the Acquired Fund attributable to Institutional Class shares of
the Acquired Fund transferred to the Acquiring Fund on such date less the value
of the liabilities of the Acquired Fund attributable to Institutional Class
shares of the Acquired Fund assumed by the Acquiring Fund on that date and (ii)
a number of full and fractional Administrative Class shares of beneficial
interest of the Acquiring Fund (the "Administrative Class Merger Shares") having
an aggregate net asset value equal to the value of the assets of the Acquired
Fund attributable to Administrative Class shares of the Acquired Fund
transferred to the Acquiring Fund on such date less the value of the liabilities
of the Acquired Fund attributable to Administrative Class shares of the Acquired
Fund assumed by the Acquiring Fund on that date.  (The Institutional Class
Merger Shares and


                                      A-1
<PAGE>
 
the Administrative Class Merger Shares shall be referred to collectively as the
"Merger Shares.")  It is intended that the reorganization described in this Plan
shall be a reorganization within the meaning of Section 368 of the Internal
Revenue Code of 1986, as amended (the "Code").

          (c) Upon consummation of the transactions described in paragraph (b)
of this Plan of Reorganization, the Acquired Fund shall distribute in complete
liquidation to its Institutional Class and Administrative Class shareholders of
record as of the Exchange Date Institutional Class and Administrative Class,
each shareholder being entitled to receive that proportion of such Institutional
Class and Administrative Class Merger Shares which the number of Institutional
Class and Administrative Class shares of beneficial interest of the Acquired
Fund held by such shareholder bears to the number of Institutional Class and
Administrative Class shares of the Acquired Fund outstanding on such date.
Certificates representing the Merger Shares will not be issued.  All issued and
outstanding shares of the Acquired Fund will simultaneously be canceled on the
books of the Acquired Fund.

          (d)  As promptly as practicable after the liquidation of the Acquired
Fund as aforesaid, the Acquired Fund shall be dissolved pursuant to the
provisions of the Declaration of Trust of the PFEAS Trust, as amended, and
applicable law, and its legal existence terminated.  Any reporting
responsibility of the Acquired Fund is and shall remain the responsibility of
the Acquired Fund up to and including the Exchange Date and, if applicable, such
later date on which the Acquired Fund is liquidated.

                                   AGREEMENT
                                   ---------

          The Acquiring Fund and the Acquired Fund agree as follows:

          1.  Representations, Warranties and Agreements of the Acquiring Fund.
              ----------------------------------------------------------------

              obligations under this Agreement. The PFEAS Trust is qualified as
              a foreign association in every jurisdiction where required, except
              to the extent that failure to so qualify would not have a material
              adverse effect on the PFEAS Trust. Each of the PFEAS Trust and the
              Acquiring Fund has all necessary federal, state and local
              authorizations to carry on its business as now being conducted and
              to carry out this Agreement.

          b.  The PFEAS Trust is registered under the Investment Company Act of

effect.

c.  [Reserved.]

d.  The prospectus and statement of additional information of the PFEAS Trust,

    material fact or omit to state a material fact required to be stated therein
    or necessary to make the statements therein not misleading.

e.  There are no material legal, administrative or other proceedings pending or,
    to the knowledge of the PFEAS Trust or the Acquiring Fund, threatened
    against the PFEAS Trust or the Acquiring Fund, which assert liability on the
    part of the PFEAS Trust or the Acquiring Fund. The Acquiring Fund knows of
    no facts which might form the basis for the institution of such proceedings
    and is not a party to or subject to the provisions of any order, decree or
    judgment of any court or governmental body which materially and adversely
    affects its business or its ability to consummate the transactions herein
    contemplated.

    any assessments received by the Acquiring Fund. All tax liabilities of the
    Acquiring Fund have been adequately provided for on its books, and no tax
    deficiency or liability of the Acquiring Fund has been asserted, and no
    question with respect thereto has been raised or is under audit, by the
    Internal Revenue Service or by any state or local tax authority for taxes in
    excess of those already paid.

h.  No consent, approval, authorization or order of any court or governmental
    authority is required for the consummation by the Acquiring Fund of the
    transactions contemplated by this Agreement, except such as may be required
    under the Securities Act of 1933, as amended (the "1933 Act"), the
    Securities Exchange Act of 1934, as amended (the "1934 Act"), the 1940 Act
    and state securities or blue sky laws (which term as used herein shall

    reliance upon and in conformity with information furnished by the Acquired
    Fund for use in the Registration Statement or the Acquired Fund Proxy
    Statement.

k.  The Acquiring Fund has [no] shares of beneficial interest issued and
    outstanding and all shares of beneficial interest to be issued and
    outstanding at the consummation of the transaction contemplated herein will
    have been offered for sale and sold in conformity with all applicable
    federal and state securities laws (including any applicable exemptions
    therefrom), or the Acquiring Fund will have taken any action necessary to
    remedy any prior failure to have offered for sale and sold such shares in

    shares.

2.  Representations, Warranties and Agreements of the Acquired Fund.
    ---------------------------------------------------------------  
    The Acquired Fund represents and warrants to and agrees with the Acquiring
    Fund that :

a.  The Acquired Fund is a series of shares of the PFEAS Trust, a Massachusetts
    business trust duly established and validly existing under the laws of The
    Commonwealth of Massachusetts, and has power to own all of its properties
    and assets and to carry out this Agreement. The PFEAS Trust is qualified as
    a foreign association in every jurisdiction where required, except to the
    extent that failure to so qualify would not have a material adverse effect
    on the PFEAS Trust. Each of the PFEAS Trust and the Acquired Fund has all
    necessary federal, state and local authorizations to own all of its
    properties and assets and to carry on its business as now being conducted
    and to carry out this Agreement.

b.  The PFEAS Trust is registered under the 1940 Act as an open-end management
    investment company, and such registration has not been revoked or rescinded
    and is in full force and effect.

c.  A statement of assets and liabilities, statements of operations, statements
    of changes in net assets and a schedule of investments (indicating their
    market values) of the Acquired Fund as of and for the six months ended June
    30, 1996 have been furnished to the Acquiring Fund. Such statement of assets
    and liabilities and schedule fairly present the financial position of the
    Acquired Fund as of their date and said statements of operations and changes
    in net assets fairly reflect the results of its operations and changes in
    net assets for the periods covered thereby in conformity with generally
    accepted accounting principles.

d.  The PFEAS Prospectus, which has been previously furnished to the Acquiring
    Fund, did not contain as of such dates and does not contain, with respect to
    the


                                      A-5
<PAGE>
 
    PFEAS Trust and the Acquired Fund, any untrue statement of a material fact
    or omit to state a material fact required to be stated therein or necessary
    to make the statements therein not misleading.

e.  There are no material legal, administrative or other proceedings pending or,
    to the knowledge of the PFEAS Trust or the Acquired Fund, threatened against
    the PFEAS Trust or the Acquired Fund, which assert liability on the part of
    the PFEAS Trust or the Acquired Fund. The Acquired Fund knows of no facts
    which might form the basis for the institution of such proceedings and is
    not a party to or subject to the provisions of any order, decree or judgment
    of any court or governmental body which materially and adversely affects its
    business or its ability to consummate the transactions herein contemplated.

f.  There are no material contracts outstanding to which the Acquired Fund is a
    party, other than as will be disclosed in the Registration Statement, the
    PFEAS Prospectus or the Acquired Fund Proxy Statement.

g.  The Acquired Fund has no known liabilities of a material nature, contingent
    or otherwise, other than those shown on the Acquired Fund's statement of
    assets and liabilities as of June 30, 1996 referred to above and those
    incurred in the ordinary course of its business as an investment company
    since such date. Prior to the Exchange Date, the Acquired Fund will endeavor
    to quantify and to reflect on its balance sheet all of its material known
    liabilities and will advise the Acquiring Fund of all material liabilities,
    contingent or otherwise, incurred by it subsequent to June 30, 1996, whether
    or not incurred in the ordinary course of business.

h.  As of the Exchange Date, the Acquired Fund will have filed all federal and
    other tax returns and reports which, to the knowledge of the PFEAS Trust's
    officers, are required to be filed by the Acquired Fund and has paid or will
    pay all federal and other taxes shown to be due on said returns or on any
    assessments received by the Acquired Fund. All tax liabilities of the
    Acquired Fund have been adequately provided for on its books, and no tax
    deficiency or liability of the Acquired Fund has been asserted, and no
    question with respect thereto has been raised or is under audit, by the
    Internal Revenue Service or by any state or local tax authority for taxes in
    excess of those already paid.

i.  At both the Valuation Time (as defined in Section 3(c)) and the Exchange
    Date, the PFEAS Trust, on behalf of the Acquired Fund, will have full right,
    power and authority to sell, assign, transfer and deliver the Investments
    and any other assets and liabilities of the Acquired Fund to be transferred
    to the Acquiring Fund pursuant to this Agreement. At the Exchange Date,
    subject only to the delivery of the Investments and any such other assets
    and liabilities as

              contemplated by this Agreement, the Acquiring Fund will acquire
              the Investments and any such other assets and liabilities subject
              to no encumbrances, liens or security interests whatsoever and
              without any restrictions upon the transfer thereof. As used in
              this Agreement, the term "Investments" shall mean the Acquired
              Fund's investments shown on the schedule of its investments as of
              June 30, 1996 referred to in Section 2(c) hereof, as supplemented
              with such changes in the portfolio as the Acquired Fund shall
              make, and changes resulting from stock dividends, stock split-ups,
              mergers and similar corporate actions through the Exchange Date.

          j.  No registration under the 1933 Act of any of the Investments would
              be required if they were, as of the time of such transfer, the
              subject of a public distribution by either of the Acquiring Fund
              or the Acquired Fund, except as previously disclosed to the
              Acquiring Fund by the Acquired Fund.

          k.  No consent, approval, authorization or order of any court or
              governmental authority is required for the consummation by the
              Acquired Fund of the transactions contemplated by this Agreement,
              except such as may be required under the 1933 Act, 1934 Act, the
              1940 Act or state securities or blue sky laws.

          l.  The Registration Statement and the Acquired Fund Proxy Statement,
              on the effective date of the Registration Statement, (i) will
              comply in all material respects with the provisions of the 1933
              Act, the 1934 Act and the 1940 Act and the rules and regulations
              thereunder and (ii) will not contain any untrue statement of a
              material fact or omit to state a material fact required to be
              stated therein or necessary to make the statements therein not
              misleading; and at the time of the shareholders meeting referred
              to in Section 7(a) and on the Exchange Date, the Acquired Fund
              Proxy Statement and the Registration Statement will not contain
              any untrue statement of a material fact or omit to state a
              material fact required to be stated therein or necessary to make
              the statements therein not misleading; provided, however, that
              none of the representations and warranties in this subsection
              shall apply to statements in or omissions from the Registration
              Statement or the Acquired Fund Proxy Statement made in reliance
              upon and in conformity with information furnished by the Acquiring
              Fund for use in the Registration Statement or the Acquired Fund
              Proxy Statement.

          m.  The Acquired Fund qualifies and will at all times through the
              Exchange Date qualify for taxation as a "regulated investment
              company" under Section 851 and 852 of the Code.

          n.  At the Exchange Date, the Acquired Fund will have sold such of its
              assets, if any, as are necessary to assure that, after giving
              effect to the acquisition of the 

                                      A-7
<PAGE>
 
              assets of the Acquired Fund pursuant to this Agreement, the
              Acquiring Fund will remain a "diversified company" within the
              meaning of Section 5(b)(1) of the 1940 Act and in compliance with
              such other mandatory investment restrictions as are set forth in
              the PFEAS Prospectus, as amended through the Exchange Date.

          o.  To the best of its knowledge, all of the issued and outstanding
              shares of beneficial interest of the Acquired Fund shall have been
              offered for sale and sold in conformity with all applicable
              federal and state securities laws (including any applicable
              exemptions therefrom), or the Acquired Fund has taken any action
              necessary to remedy any prior failure to have offered for sale and
              sold such shares in conformity with such laws.

          p.  All issued and outstanding shares of the Acquired Fund are, and at
              the Exchange Date will be, duly and validly issued and
              outstanding, fully paid and non-assessable by the Acquired Fund.
              The Acquired Fund does not have outstanding any options, warrants
              or other rights to subscribe for or purchase any of the Acquired
              Fund shares, nor is there outstanding any security convertible
              into any of the Acquired Fund shares.

          3.  Reorganization.
              -------------- 

          a.  Subject to the requisite approval of the shareholders of the
              Acquired Fund and the consummation of the PAF Reorganization and
              to the other terms and conditions contained herein (including the
              Acquired Fund's obligation to distribute to its shareholders all
              of its investment company taxable income and net capital gain as
              described in Section 8(m)), the Acquired Fund agrees to sell,
              assign, convey, transfer and deliver to the Acquiring Fund, and
              the Acquiring Fund agrees to acquire from the Acquired Fund, on
              the Exchange Date all of the Investments and all of the cash and
              other properties and assets of the Acquired Fund, whether accrued
              or contingent (including cash received by the Acquired Fund upon
              the liquidation of the Acquired Fund of any investments purchased
              by the Acquired Fund after June 30, 1996 and designated by the
              Acquiring Fund as being unsuitable for it to acquire), in exchange
              for that number of shares of beneficial interest of the Acquiring
              Fund provided for in Section 4 and the assumption by the Acquiring
              Fund of all of the liabilities of the Acquired Fund, whether
              accrued or contingent, existing at the Valuation Time except for
              the Acquired Fund's liabilities, if any, arising in connection
              with this Agreement. Pursuant to this Agreement, the Acquired Fund
              will, as soon as practicable after the Exchange Date, distribute
              all of the Merger Shares received by it to the shareholders of the
              Acquired Fund in exchange for their Institutional Class and
              Administrative Class shares of the Acquired Fund.

                                      A-8
<PAGE>
 
          b.  The Acquired Fund will pay or cause to be paid to the Acquiring
              Fund any interest, cash or such dividends, rights and other
              payments received by it on or after the Exchange Date with respect
              to the Investments and other properties and assets of the Acquired
              Fund, whether accrued or contingent, received by it on or after
              the Exchange Date. Any such distribution shall be deemed included
              in the assets transferred to the Acquiring Fund at the Exchange
              Date and shall not be separately valued unless the securities in
              respect of which such distribution is made shall have gone "ex"
              such distribution prior to the Valuation Time, in which case any
              such distribution which remains unpaid at the Exchange Date shall
              be included in the determination of the value of the assets of the
              Acquired Fund acquired by the Acquiring Fund.

          c.  The Valuation Time shall be 4:00 p.m. Eastern time on [the
              Exchange Date] or such earlier or later day as may be mutually
              agreed upon in writing by the parties hereto (the "Valuation
              Time").

          4.  Exchange Date: Valuation Time.  On the Exchange Date, the
              -----------------------------                            
              Acquiring Fund will deliver to the Acquired Fund (i) a number of
              full and fractional Institutional Class Merger Shares having an
              aggregate net asset value equal to the value of the assets of the
              Acquired Fund attributable to Institutional Class shares of the
              Acquired Fund transferred to the Acquiring Fund on such date less
              the value of the liabilities of the Acquired Fund attributable to
              Institutional Class shares of the Acquired Fund assumed by the
              Acquiring Fund on that date, (ii) a number of full and fractional
              Administrative Class Merger Shares having an aggregate net asset
              value equal to the value of the assets of the Acquired Fund
              attributable to Administrative Class shares of the Acquired Fund
              transferred to the Acquiring Fund on such date less the value of
              the liabilities of the Acquired Fund attributable to
              Administrative Class shares of the Acquired Fund assumed by the
              Acquiring Fund on that date, determined as hereinafter provided in
              this Section 4.

          a.  The net asset value of the Merger Shares to be delivered to the
              Acquired Fund, the value of the assets attributable to the shares
              of the Acquired Fund, and the value of the liabilities
              attributable to the Institutional Class and Administrative Class
              shares of the Acquired Fund to be assumed by the Acquiring Fund,
              shall in each case be determined as of the Valuation Time.

          b.  The net asset value of the Institutional Class and Administrative
              Class Merger Shares shall be computed in the manner set forth in
              the PFEAS Prospectus. The value of the assets and liabilities of
              the Institutional Class and Administrative Class shares of the
              Acquired Fund shall be determined by the Acquiring Fund, in
              cooperation with the Acquired Fund, pursuant to procedures 

                                      A-9
<PAGE>
 
              which the Acquiring Fund would use in determining the fair market
              value of the Acquiring Fund's assets and liabilities.

          c.  No adjustment shall be made in the net asset value of either the
              Acquired Fund or the Acquiring Fund to take into account
              differences in realized and unrealized gains and losses.

          d.  The Acquiring Fund shall issue the Merger Shares to the Acquired
              Fund in two certificates registered in the name of the Acquired
              Fund, one representing Institutional Class Merger Shares and one
              representing Administrative Class Merger Shares. The Acquired Fund
              shall distribute the Institutional Class Merger Shares to the
              Institutional Class shareholders of the Acquired Fund by
              redelivering such certificate to the Acquiring Fund's transfer
              agent, which will as soon as practicable set up open accounts for
              each Institutional Class Acquired Fund shareholder in accordance
              with written instructions furnished by the Acquired Fund. The
              Acquired Fund shall distribute the Administrative Class Merger
              Shares to the Administrative Class shareholders of the Acquired
              Fund by redelivering such certificate to the Acquiring Fund's
              transfer agent, which will as soon as practicable set up open
              accounts for each Administrative Class Acquired Fund shareholder
              in accordance with written instructions furnished by the Acquired
              Fund. With respect to any Acquired Fund shareholder holding share
              certificates as of the Exchange Date, such certificates will from
              and after the Exchange Date be deemed to be certificates for the
              Merger Shares issued to each shareholder in respect of the
              Acquired Fund shares represented by such certificates;
              certificates representing the Merger Shares will not be issued to
              Acquired Fund shareholders.

          e.  The Acquiring Fund shall assume all liabilities of the Acquired
              Fund, whether accrued or contingent, in connection with the
              acquisition of assets and subsequent dissolution of the Acquired
              Fund or otherwise, except for the Acquired Fund's liabilities, if
              any, pursuant to this Agreement.

          5.  Expenses, Fees, etc.
              -------------------

          a.  The parties hereto understand and agree that the transactions
              contemplated by this Agreement are being undertaken
              contemporaneously with a general restructuring and consolidation
              of certain of the registered investment companies advised by PIMCO
              Advisors L.P. and its affiliates; and that in connection therewith
              the costs of all such transactions are being preliminarily
              allocated on a basis approved, inter alia, by the Trustees of the
                                             ----------
              PFEAS Trust. The Acquired Fund agrees to pay the expenses
              preliminarily allocated to it but not, however, in an amount
              exceeding $20,000 (the "Relevant Expense Cap"). PIMCO Advisors
              L.P., by countersigning this Agreement, agrees that PIMCO

                                      A-10
<PAGE>
 
              Advisors L.P. will bear any and all expenses (1) preliminarily
              allocated to Acquiring Fund and (2) preliminarily allocated to the
              Acquired Fund to the extent that they would otherwise exceed the
              Relevant Expense Cap. Notwithstanding any of the foregoing,
              expenses will in any event be paid by the party directly incurring
              such expenses if and to the extent that the payment by the other
              party of such expenses would result in the disqualification of
              such party as a "regulated investment company" within the meaning
              of Section 851 of the Code.

          b.  In the event the transactions contemplated by this Agreement are
              not consummated by reason of the Acquiring Fund's being either
              unwilling or unable to go forward other than by reason of the
              nonfulfillment or failure of any condition to the Acquiring Fund's
              obligations referred to in Section 7(a) or Section 8, the
              Acquiring Fund shall pay directly all reasonable fees and expenses
              incurred by the Acquired Fund in connection with such
              transactions, including, without limitation, legal, accounting and
              filing fees.

          c.  In the event the transactions contemplated by this Agreement are
              not consummated by reason of the Acquired Fund's being either
              unwilling or unable to go forward other than by reason of the
              nonfulfillment or failure of any condition to the Acquired Fund's
              obligations referred to in Section 7(a) or Section 9, the Acquired
              Fund shall pay directly all reasonable fees and expenses incurred
              by the Acquiring Fund in connection with such transactions,
              including, without limitation, legal, accounting and filings fees.

          d.  In the event the transactions contemplated by this Agreement are
              not consummated for any reason other than (i) the Acquiring Fund's
              or the Acquired Fund's being either unwilling or unable to go
              forward or (ii) the nonfulfillment or failure of any condition to
              the Acquiring Fund's or the Acquired Fund's obligations referred
              to in Section 7(a), Section 8 or Section 9 of this Agreement, then
              each of the Acquiring Fund and the Acquired Fund shall bear all of
              its own expenses incurred in connection with such transactions.

          e.  Notwithstanding any other provisions of this Agreement, if for any
              reason the transactions contemplated by this Agreement are not
              consummated, no party shall be liable to the other party for any
              damages resulting therefrom, including, without limitation,
              consequential damages, except as specifically set forth above.

          6.  Exchange Date.  Delivery of the assets of the Acquired Fund to be
              -------------                                                    
              transferred, assumption of the liabilities of the Acquired Fund to
              be assumed, and the delivery of the Merger Shares to be issued
              shall be made at [place] at [time] as of [January___, 1997], or at
              such other time and date agreed to by the Acquiring

                                      A-11

              Fund and the Acquired Fund, the date and time upon which such
              delivery is to take place being referred to herein as the
              "Exchange Date."

          7.  Meetings of Shareholders; Dissolution.
              ------------------------------------- 

          a.  The PFEAS Trust, on behalf of the Acquired Fund, agrees to call a
              meeting of the Acquired Fund's shareholders as soon as is
              practicable after the effective date of the Registration Statement
              for the purpose of considering the sale of all of its assets to
              and the assumption of all of its liabilities by the Acquiring Fund
              as herein provided, adopting this Agreement, and authorizing the
              liquidation and dissolution of the Acquired Fund.

          b.  The Acquired Fund agrees that the liquidation and dissolution of
              the Acquired Fund will be effected in the manner provided in the
              PFEAS Trust's Declaration of Trust in accordance with applicable
              law and that on and after the Exchange Date, the Acquired Fund
              shall not conduct any business except in connection with its
              liquidation and dissolution.

          c.  [Reserved.]

          d.  The Acquiring Fund has, after the preparation and delivery to the
              Acquiring Fund by the Acquired Fund of a preliminary version of
              the Acquired Fund Proxy Statement which was satisfactory to the
              Acquiring Fund and to Dechert Price & Rhoads for inclusion in the
              Registration Statement, filed the Registration Statement with the
              Commission. Each of the Acquired Fund and the Acquiring Fund will
              cooperate with the other, and each will furnish to the other the
              information relating to itself required by the 1933 Act, the 1934
              Act and the 1940 Act and the rules and regulations thereunder to
              be set forth in the Registration Statement.

          8.  Conditions to the Acquiring Fund's Obligations.  The obligations
              ----------------------------------------------                  
              of the Acquiring Fund hereunder shall be subject to the following
              conditions:

          a.  That this Agreement shall have been adopted and the transactions
              contemplated hereby shall have been approved by the requisite

              interest of the Acquired Fund entitled to vote.

          b.  That the Acquired Fund shall have furnished to the Acquiring Fund
              a statement of the Acquired Fund's assets and liabilities, with
              values determined as provided in Section 4 of this Agreement,
              together with a list of Investments with their respective tax
              costs, all as of the Valuation Time, certified on the Acquired
              Fund's behalf by the PFEAS Trust's President (or any Vice
              President) and Treasurer, and a certificate of both such officers,
              dated the Exchange Date, that

<PAGE>
 
              there has been no material adverse change in the financial
              position of the Acquired Fund since June 30, 1996 other than
              changes in the Investments and other assets and properties since
              that date or changes in the market value of the Investments and
              other assets of the Acquired Fund, or changes due to dividends
              paid or losses from operations.

          c.  That the Acquired Fund shall have furnished to the Acquiring Fund

              of the Valuation Time and as of the Exchange Date all
              representations and warranties of the Acquired Fund made in this
              Agreement are true and correct in all material respects as if made
              at and as of such dates and the Acquired Fund has complied with
              all the agreements and satisfied all the conditions on its part to
              be performed or satisfied at or prior to such dates.

          d.  That the Acquired Fund shall have delivered to the Acquiring Fund
              a letter from Price Waterhouse LLP dated the Exchange Date stating
              that such firm has employed certain procedures whereby it has
              obtained schedules of the tax provisions and qualifying tests for
              regulated investment companies as prepared for the fiscal year
              ended June 30, 1996 and the period July 1, 1996 to the Exchange
              Date (the latter period being based on unaudited data) and that,
              in the course of such procedures, nothing came to their attention
              which caused them to believe that the Acquired Fund (i) would not
              qualify as a regulated investment company for federal, state, or
              local income tax purposes or (ii) would owe any federal, state or
              local income tax or excise tax, for the tax year ended June 30,
              1996, and for the period from July 1, 1996 to the Exchange Date.

          e.  That there shall not be any material litigation pending with
              respect to the matters contemplated by this Agreement.

          f.  That the Acquiring Fund shall have received an opinion of Dechert
              Price & Rhoads, counsel to the Acquiring Fund, and dated the
              Exchange Date, to the effect that (i) the PFEAS Trust is a
              Massachusetts business trust duly formed and is validly existing
              under the laws of The Commonwealth of Massachusetts and has the
              power to own all its properties and to carry on its business as
              presently conducted; (ii) this Agreement has been duly authorized,
              executed and delivered by the PFEAS Trust on behalf of the
              Acquired Fund and, assuming that the Registration Statement, the
              PFEAS Prospectus and the Acquired Fund Proxy Statement comply with
              the 1933 Act, the 1934 Act and the 1940 Act and assuming due
              authorization, execution and delivery of this Agreement by the
              PFEAS Trust on behalf of the Acquiring Fund, is a valid and
              binding obligation of the PFEAS Trust and the Acquired Fund; (iii)
              the PFEAS Trust, on behalf of the Acquired Fund, has power to
              sell, assign, convey, transfer and deliver the 

                                      A-13

              assets contemplated hereby and, upon consummation of the
              transactions contemplated hereby in accordance with the terms of
              this Agreement, the Acquired Fund will have duly sold, assigned,
              conveyed, transferred and delivered such assets to the Acquiring
              Fund; (iv) the execution and delivery of this Agreement did not,
              and the consummation of the transactions contemplated hereby will
              not, violate the PFEAS Trust's Declaration of Trust or By-Laws or
              any provision of any agreement known to such counsel to which the
              PFEAS Trust or the Acquired Fund is a party or by which it is
              bound, it being understood that with respect to investment
              restrictions as contained in the PFEAS Trust's Declaration of
              Trust, By-Laws or then-current prospectus or statement of
              additional information, such counsel may rely upon a certificate
              of an officer of the PFEAS Trust whose responsibility it is to
              advise the PFEAS Trust and the Acquired Fund with respect to such
              matters; and (v) no consent, approval, authorization or order of
              any court or governmental authority is required for the
              consummation by the PFEAS Trust on behalf of the Acquired Fund of
              the transactions contemplated hereby, except such as have been
              obtained under the 1933 Act, the 1934 Act and the 1940 Act and
              such as may be required under state securities or blue sky laws.
              In addition, such counsel shall also state that they have
              participated in conferences with officers and other
              representatives of the Acquired Fund at which the contents of the
              Acquired Fund Proxy Statement and related matters were discussed,
              and, although they are not passing upon and do not assume any
              responsibility for the accuracy, completeness or fairness of the
              statements contained in the Acquired Fund Proxy Statement, on the
              basis of the foregoing (relying as to materiality to a large
              extent upon the opinions of officers and other representatives of
              the Acquired Fund), no facts have come to their attention that
              lead them to believe that the portions of the Acquired Fund Proxy
              Statement relevant to the transfer of assets contemplated by this
              Agreement as of its date, as of the date of the Acquired Fund
              shareholders' meeting, or as of the Exchange Date, contained an
              untrue statement of a material fact regarding the Acquired Fund or
              omitted to state a material fact required to be stated therein or
              necessary to make the statements therein regarding the Acquired
              Fund, in light of the circumstances under which they were made,
              not misleading. Such opinion may state that such counsel does not
              express any opinion or belief as to the financial statements or
              other financial data, or as to the information relating to the
              Acquiring Fund, contained in the Acquired Fund Proxy Statement or
              the Registration Statement, and that such opinion is solely for
              the benefit of the Acquiring Fund, its Trustees and its officers.

          g.  That the Acquiring Fund shall have received an opinion of Ropes &
              Gray, in form satisfactory to Dechert Price & Rhoads, with respect
              to the matters specified in Section 9(g) of this Agreement, and
              such other matters as the Acquiring Fund may reasonably deem
              necessary or desirable.

              Gray, dated the Exchange Date, satisfactory to Dechert Price &
              Rhoads (which opinion would be based upon certain factual
              representations and subject to certain qualifications), to the
              effect that, on the basis of the existing provisions of the Code,
              current administrative rules, and court decisions, for federal
              income tax purposes (i) no gain or loss will be recognized by the
              Acquiring Fund upon receipt of the Investments transferred to the
              Acquiring Fund pursuant to this Agreement in exchange for the
              Merger Shares; (ii) the basis to the Acquiring Fund of the
              Investments will be the same as the basis of the Investments in
              the hands of the Acquired Fund immediately prior to such exchange;
              and (iii) the Acquiring Fund's holding periods with respect to the
              Investments will include the respective periods for which the
              Investments were held by the Acquired Fund.

          i.  That the assets of the Acquired Fund to be acquired by the
              Acquiring Fund will include no assets which the Acquiring Fund, by
              reason of charter limitations or of investment restrictions
              disclosed in the Registration Statement in effect on the Exchange
              Date, may not properly acquire.

              the 1933 Act, and no stop order suspending such effectiveness
              shall have been instituted or, to the knowledge of the PFEAS Trust

              any relevant state securities administrator such order or orders
              as are reasonably necessary or desirable under the 1933 Act, the
              1934 Act, the 1940 Act, and any applicable state securities or
              blue sky laws in connection with the transactions contemplated
              hereby, and that all such orders shall be in full force and
              effect.

          l.  That all actions taken by the PFEAS Trust on behalf of the
              Acquired Fund in connection with the transactions contemplated by
              this Agreement and all documents incidental thereto shall be
              satisfactory in form and substance to the Acquiring Fund and
              Dechert Price & Rhoads.

          m.  That, prior to the Exchange Date, the Acquired Fund shall have
              declared a dividend or dividends which, together with all previous
              such dividends, shall have the effect of distributing to the
              shareholders of the Acquired Fund [(i) all of the excess of (x)
              the Acquired Fund's investment income excludable from gross income
              under Section 103(a) of the Code over (y) the Acquired Fund's

              852 of the Code) for its taxable years ending on or after June 30,
              1996 and on or prior to the Exchange Date (computed in each case
              without regard to any deduction for dividends paid), and (iii) all
              of the Acquired Fund's net capital gain realized (after reduction
              for any capital loss carryover), in each case for both the taxable
              year ending on June 30, 1996 and the short taxable period
              beginning on July 1, 1996 and ending on the Exchange Date.

          n.  That the Acquired Fund shall have furnished to the Acquiring Fund
              a certificate, signed by the President (or any Vice President) and

              the extent that any audit of the records of the Acquired Fund or
              its transfer agent by the Acquiring Fund or its agents shall have
              revealed otherwise, either (i) the Acquired Fund shall have taken
              all actions that in the opinion of the Acquiring Fund or Dechert
              Price & Rhoads are necessary to remedy any prior failure on the

              shares in conformity with such laws or (ii) the Acquired Fund
              shall have furnished (or caused to be furnished) surety, or

              satisfactory, in the opinion of the Acquiring Fund or Dechert
              Price & Rhoads, to indemnify the Acquiring Fund against any

    omitted to state a material fact required to be stated therein or necessary

    will be recognized by shareholders of the Acquired Fund on the distribution
    of Merger Shares to them in exchange for their shares of the Acquired Fund;
    (iii) the tax basis of the Merger Shares that the Acquired Fund's

    determined by including the holding period for the Acquired Fund shares
    exchanged for the Merger Shares, provided that the shareholder held the
    Acquired Fund shares as a capital asset.

h.  That all actions taken by the PFEAS Trust on behalf of the Acquiring Fund in

    --------------- 

a.  The Acquired Fund will indemnify and hold harmless, out of the assets of the
    Acquired Fund (which shall be deemed to include the assets of the Acquiring
    Fund represented by the Merger Shares following the Exchange Date) but no
    other assets, the trustees and officers of the PFEAS Trust (for purposes of
    this subparagraph, the "Indemnified Parties") against any and all expenses,
    losses, claims, damages and liabilities at any time imposed upon or
    reasonably incurred by any one or more of the Indemnified Parties in
    connection with, arising out of, or resulting from any claim, action, suit
    or proceeding in which any one or more of the Indemnified Parties may be

    any such claim, action, suit or proceeding, or threatened claim, action,
    suit or proceeding made with the consent of the PFEAS Trust or the Acquired
    Fund. The Indemnified Parties will notify the PFEAS Trust and the Acquired
    Fund in writing within ten days after the receipt by any one or more of the

    any suit brought against or claim made against such Indemnified Party as to
    any matters covered by this Section 10(a). The Acquired Fund shall be
    entitled to participate at its own expense in the defense of any claim,
    action, suit or proceeding covered by this Section 10(a), or, if it so
    elects, to assume at its expense by counsel satisfactory to the Indemnified
    Parties the defense of any such claim, action, suit or proceeding, and if
    the Acquired Fund elects to assume such defense, the Indemnified Parties
    shall be entitled to participate in the defense of any such claim, action,
    suit or proceeding at their expense. The Acquired Fund's obligation under
    Section 10(a) to indemnify and hold harmless the Indemnified parties shall
    constitute a guarantee of payment so that the Acquired Fund will pay in the
    first instance any expenses, losses, claims, damages and liabilities
    required to be paid by it under this Section 10(a) without the necessity of
    the Indemnified Parties' first paying the same.

    the Acquiring Fund but no other assets, the trustees and officers of the
    PFEAS Trust (for purposes of this subparagraph, the "Indemnified Parties")
    against any and all expenses, losses, claims, damages and liabilities at any
    time imposed upon or reasonably incurred by any one or more of the
    Indemnified Parties in connection with, arising out of, or resulting from
    any claim, action, suit or proceeding in which any one or more of the
    Indemnified Parties may be involved or with which any one or more of the
    Indemnified Parties may be threatened by reason of any untrue statement or
    alleged untrue statement of a material fact relating to the Acquiring Fund
    contained in the Registration Statement, the PFEAS Prospectus, the Acquired
    Fund Proxy Statement or any amendment or supplement to any of the foregoing,
    or arising out of or based upon, the omission or alleged omission to state
    in any of the foregoing a material fact relating to the PFEAS Trust or the
    Acquiring Fund required to be stated therein or necessary to make the
    statements relating to the PFEAS Trust or the Acquiring Fund therein not
    misleading, including, without limitation, any amounts paid by any one or
    more of the Indemnified Parties in a reasonable compromise or settlement of
    any such claim, action, suit or proceeding, or threatened claim, action,
    suit or proceeding made with the consent of the PFEAS Trust or the Acquiring
    Fund. The Indemnified Parties will notify the PFEAS Trust and the Acquiring
    Fund in writing within ten days after the receipt by any one or more of the
    Indemnified parties of any notice of legal process or any suit brought
    against or claim made against such Indemnified Party as to any matters
    covered by this Section 10(b). The Acquiring Fund shall be entitled to
    participate at its own expense in the defense of any claim, action, suit or
    proceeding covered by this Section 10(b), or, if it so elects, to assume at
    its expense by counsel satisfactory to the Indemnified Parties the defense
    of any such clam, action, suit or proceeding, and, if the Acquiring Fund
    elects to assume such defense, the Indemnified Parties shall be entitled to

                                      A-21

    participate in the defense of any such claim, action, suit or proceeding at
    their own expense. The Acquiring Fund's obligation under this Section 10(b)
    to indemnify and hold harmless the Indemnified Parties shall constitute a
    guarantee of payment so that the Acquiring Fund will pay in the first
    instance any expenses, losses, claims, damages and liabilities required to
    be paid by it under this Section 10(b) without the necessity of the
    Indemnified Parties' first paying the same.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

The Growth Fund continued to outperform the Lipper Growth Fund Average, for both
the long- and short-term. Over the ten-year period ended March 31, 1996 the C
shares returned 13.9% annualized, outdistancing the Lipper Growth Fund Average,
while the six-month gain of 8.8% also surpassed its Lipper average.

     Technology, finance, and healthcare were the Fund's largest three sectors
for the six-month period ended March 31, 1996, with their percentage of the
portfolio remaining relatively constant over that time.

     The technology portion of the Fund performed well in the first three months
of 1996 after a weak fourth quarter of 1995. In the fourth quarter, excess
inventories in the semiconductor industry led to significant price declines for
many products as demand decelerated while capacity growth was accelerating. This
prompted the manager to decrease the Funds commodity oriented semiconductor
companies in favor of technology companies benefiting from strong long-term
trends. Examples included Microsoft and Cisco Systems, Inc.

     In the finance sector, after bank takeovers dominated the fourth quarter
performance to the disadvantage of the Fund, emphasis shifted back to company
specific stories in the first quarter. Chemical Bank was a stellar performer,
benefiting from a growing awareness of significant cost savings due to its
merger with Chase Bank. Green Tree Financial's expansion into new markets and
market share gains in their core manufactured housing market also continued to
exceed investor expectations and were rewarded with strong stock price
performance.

     Aided by an aging population, a shortening of approval process for new
products from the Federal Food & Drug Administration, and a rotation by
investors to defensive stocks, the healthcare sector played a major role in the
Growth Fund's success for the period. Examples included Columbia Healthcare (a
manager of healthcare facilities) and Merck & Co. (a pharmaceutical firm).

     Late in the quarter evidence began pointing to a stronger than expected
economy and investors responded by focusing on cyclical companies. The Fund
participated in this trend to a modest degree as the stronger economy has led to
positive surprise in select cyclical industries. On balance though, the evidence
suggests that economic growth is only at a modest pace and the manager remains
weighted toward beneficiaries of longer-term trends and positively surprising
internal changes, such as consolidations and restructuring. By seeking good
companies that are surprising the market with positive results, the manager
feels the Fund could perform well in this type of economic environment.

PORTFOLIO INSIGHTS
- --------------------------------------------------------------------------------

For the six-months ended March 31, 1996, the PIMCO Advisors Target Fund Class A
posted an 8.6% return and the B and C shares returned 8.1%. These results
outperformed the Lipper Mid-Cap Fund Average and the Standard & Poor's Mid-Cap
Index for that period. The Fund has also surpassed these benchmarks since its
December 17, 1992 inception, with an annualized return of 20%.

     Performance for the fourth quarter of 1995 was affected by a slowing in the
Fund's largest sector, technology. This trend continued into the first quarter
due to a decreasing demand in the semiconductor industry. The overall weighting
in the technology sector was slightly reduced, and underperforming holdings
related to semiconductors, including MEMC Electronics and Vishay
Intertechnology, were deleted from the portfolio in the first quarter, with more
concentration being placed on Internet-related companies. Examples of these
networking holdings are Fore Systems (a high-performance network product
manufacturer), and Ascend Communications (a developer of network access
products).

     The Fund's relative performance was also somewhat hurt by a "flight to
quality" in the financial markets. This occurs when investors look for stability
in company names that they recognize and feel comfortable with. Because the
majority of these are large capitalization companies, the small- and mid-cap
stocks are often negatively affected during these shifts. The first quarter was
an example of this movement, and as a result, the manager searched for more
"special situations", or companies whose prices are driven by company-specific
factors, not by industry or economic trends.

     Several examples of "special situation" companies in the Target Fund that
were top contributors in the last six months were Harley Davidson (strong
performance following the announced sale of its troubled non-motorcycle
operations), HFS, Inc. (a hotel and real estate brokerage franchiser whose
string of positive announcements regarding new vendor programs were additive to
earnings), and Guidant Corp. (a medical device manufacturer that performed well
after several new product approvals).

     One of the Target Fund's newest sectors, the oil service group, benefited
as strong demand and limited supply of drilling rigs and vessels pushed
utilization and rates to multi-year highs. Diamond Offshore Drilling and Ensco
International were two additions involved in offshore contract drilling.

     Going forward, the manager believes its special situation and technology
holdings will continue to play an important part in the Fund's performance.
Also, in order to capitalize on what appears to be a moderately growing economy,
the manager intends to increase exposure to economically sensitive companies.

PIMCO ADVISORS FUNDS FOOTNOTES
- --------------------------------------------------------------------------------

A few notes and definitions are needed for a complete understanding of the
performance figures.

Results represent past performance, not future results. Investment return will
fluctuate and the value of an investor's shares will fluctuate and may be worth
more or less than original cost when redeemed. Total return measures
performance, assuming that all dividends and capital gains distributions were
reinvested. Average annual total returns for more than one year assume a steady
compound rate of return.

Total return, both with and without a sales charge, has been presented. For
shareholders who have not bought or sold shares during the period quoted, the
non-adjusted figures are probably more meaningful than the adjusted figures. The
adjusted figures for Class A shares include the effect of paying the maximum
initial sales charge of either 5.5% (for all stock funds), 4.75% (Global Income,
High Income, Total Return Income, Tax Exempt and U.S. Government Funds), or
3.00% (Short-Intermediate Fund). The adjusted figures for Class B shares include
the effect of paying the 5% contingent deferred sales charge (CDSC), which
declines from 5% in the first year to 0% at the beginning of the seventh year.
The adjusted figures for Class C shares includes the effect of paying the 1%
CDSC which may apply to shares redeemed during the first year of ownership.

+ Yield is quoted in accordance with current Securities and Exchange Commission
regulations and is based on the one-month period ended March 31, 1996.

Line graphs have been included so an investor can compare a Fund's historical
performance to that of an appropriate broad based index. Each index reflects a
group of unmanaged securities, and it is not possible to invest in an unmanaged
index. The Standard & Poor's 500 and Standard & Poor's Mid-Cap are indices of
stocks of companies with larger- and medium-sized capitalizations, respectively.
The Russell 2000 is an index of stocks of companies with small capitalizations.
The MSCI EAFE is an index of foreign stocks. The Philadelphia Gold and Silver
Index is an index of stocks of companies in the gold and silver mining industry.

The Salomon Brothers Currency-Hedged World Government Bond Index is an index of
currency-hedged U.S. and foreign government bonds. The Lehman BB Intermediate
Bond Index is an index of intermediate-term bonds with a BB rating. The Lehman
Aggregate Bond Index is an index of a variety of bonds. The Lehman Municipal
Bond Index is an index of municipal securities rated Baa or better. The Lehman
Government Index is an index of various government securities and the Lehman
Government 1-3 year Index is an index of a variety of government securities with
1-3 year maturities. Duration is a measurement of a Fund's price sensitivity
expressed in years.

Lipper averages are calculated by Lipper Analytical Services, Inc., a nationally
recognized mutual fund performance evaluation firm. They are performance
averages of those funds that are tracked by Lipper, with the investment
objective noted. Lipper rankings are based on total returns, not adjusted for
sales charges.

The PIMCO Advisors stock funds can invest in foreign securities and the
International Fund invests primarily in these securities, which can involve
special risks due to foreign economic and political developments. The
Opportunity and Discovery Funds generally invest in small-cap stocks, which can
be riskier than the overall stock market. The Innovation and Precious Metals
Funds concentrate their portfolios thereby possibly making them more volatile
than a more diversified stock portfolio, and, therefore, should be considered as
only part of a diversified portfolio. The High Income, Total Return Income and
Short-Intermediate Funds can invest a portion of their assets in foreign bonds,
and the Global Income Fund invests primarily in these securities, which entails
special risks. These Funds and the Tax Exempt Fund can invest in high yield
bonds, which entail greater risk, such as less liquidity and possibility of
default. The U.S. Government Fund is not guaranteed by the U.S. government.

Fund (the "Target Fund," and together with the Growth Fund, the "Acquiring
Funds"), each of which is also a series of the Trust.

     This Statement of Additional Information contains information which may be
of interest to shareholders but which is not included in the Prospectus/Proxy
Statement dated October __, 1996 (the "Prospectus/Proxy Statement") of the Trust

all the liabilities of the Acquired Fund.  Each Acquired Fund would distribute
the Acquiring Fund shares it receives to its shareholders in complete
liquidation of the Acquired Fund.

 II. Financial Statements.

        This Statement of Additional Information is accompanied by the Trust's
Annual Report for the fiscal year ended June 30, 1996 and the PAF Trust's Semi-
Annual Report for the six-month period ended March 31, 1996 which contain
historical financial information regarding the Acquired Funds and the PAF Funds,
respectively. Such reports have been filed with the Securities and Exchange
Commission and are incorporated herein by reference. The PAF Trust's current
Statement of Additional Information which accompanies this Statement of
Additional Information includes financial statements for the PAF Funds from the
PAF Trust's Annual Report for the fiscal year ended September 30, 1995. Because
the assets of the Core Fund and the Mid Cap Fund each represent less than ten
percent of the assets of their respective Acquiring Funds, pro forma financial
statements for the Acquiring Funds are not provided.

Item 15.  Indemnification.

          Reference is made to Article 5, Section 5.4 of the Amended and
Restated Agreement and Declaration of Trust (the "Agreement and Declaration of
Trust") of PIMCO Funds: Equity Advisors Series (the "Registrant") which is
incorporated herein by reference.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to directors, officers and
controlling persons of the Registrant by the Registrant pursuant to the
Agreement and Declaration of Trust, its By-Laws or otherwise, the Registrant is
aware that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and, therefore,
is 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 directors, officers or controlling persons of the Registrant in
connection with the successful defense of any action, suit or proceeding) is
asserted by such directors, officers or controlling persons in connection with
shares 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 Act and will be governed by the final
adjudication of such issues.

Item 17.  Undertakings.

 (a) The undersigned Registrant agrees that prior to any public reoffering of
     the securities registered through the use of a prospectus which is a part
     of this Registration Statement by any person or party who is deemed to be
     an

                                      -3-
<PAGE>
 
     underwriter within the meaning of Rule 145(c) under the Securities Act of

                             AMENDED AND RESTATED
                         INVESTMENT ADVISORY AGREEMENT


          AGREEMENT, made the 15th day of November, 1994 and amended and
restated effective as of this ___ day of _________, 199__ between PIMCO 
Funds:  Multi-Manager Series ("Trust"), a Massachusetts business trust, 
and PIMCO Advisors L.P. ("Adviser"), a limited partnership.


          WHEREAS, the Trust is registered with the Securities and Exchange 
Commission ("SEC") as an open-end management investment company under the 
Investment Company Act of 1940, as amended (the "1940 Act"); and

          WHEREAS, the Trust is authorized to issue shares of beneficial 
interest ("Shares") in separate series with each such series representing 
interests in a separate portfolio of securities and other assets; and


          WHEREAS, the Trust has established multiple series, including 
operational series or series that are expected to be operational that are
designated as the PIMCO International Fund, PIMCO International Developed Fund,
PIMCO Emerging Markets Fund, PIMCO Capital Appreciation Fund, PIMCO Mid Cap
Growth Fund, PIMCO Small Cap Growth Fund, PIMCO Micro Cap Growth Fund, PIMCO
Renaissance Fund, PIMCO Growth Fund, PIMCO Target Fund, PIMCO Opportunity Fund,
PIMCO Innovation Fund, PIMCO Tax Exempt Fund, PIMCO Equity Income Fund, PIMCO
Value Fund, PIMCO Small Cap Value Fund, PIMCO Enhanced Equity Fund, PIMCO
Structured Emerging Markets Fund, PIMCO Balanced Fund and PIMCO Precious Metals
Fund, such series together with any other series subsequently established by the
Trust, with respect to which the Trust desires to retain the Adviser to render
investment advisory services hereunder, and with respect to which the Adviser is
willing to do so, being herein collectively referred to also as the "Funds"; and


          WHEREAS, the Adviser is registered with the SEC as an investment
adviser under the Investment Advisers Act of 1940; and


          WHEREAS, the Adviser is the parent company or an affiliate of other

investment advisers under the Investment Advisers Act of 1940; and
<PAGE>
 
          WHEREAS, the Trust desires to retain the Adviser so that it and its
subsidiaries and affiliates will render investment advisory services to the
Funds in the manner and on the terms hereinafter set forth; and


          WHEREAS, the Adviser is willing to render such services and engage its
subsidiaries, affiliates, and others to render such services to the Trust;


          NOW, THEREFORE, in consideration of the premises, the promises, and
mutual covenants herein contained, it is agreed between the parties as follows:


          1.  Appointment.  The Trust hereby appoints the Adviser to provide 
              -----------
investment advisor services to the Trust with respect to the Funds for the
period and on the terms set forth in this Agreement. The Adviser accepts such
appointment and agrees to render the services herein set forth for the
compensation herein provided.


          In the event the Trust establishes and designates additional series
with respect to which it desires to retain the Adviser to render investment
advisory services hereunder, it shall notify the Adviser in writing. If the
Adviser is willing to render such services it shall notify the Trust in writing,
whereupon such additional series shall become a Fund hereunder.


          2.  Duties.  Subject to the general supervision of the Board of
              ------
Trustees, the Adviser shall provide general, overall advice and guidance with
respect to the Funds and provide advice and guidance to the Trust's Trustees. In
discharging these duties the Adviser shall, either directly or indirectly
through others ("Portfolio Managers") engaged by it pursuant to Section 3 of
this Agreement, provide a continuous investment program for each Fund and
determine the composition of the assets of each Fund, including determination of
the purchase, retention, or sale of the securities, cash, and other investments
for the Fund. The Adviser (or Portfolio Manager) will provide investment
research and analysis, which may consist of a computerized investment
methodology, and will conduct a continuous program of evaluation, investment,
sales, and reinvestment of the Fund assets by determining the securities and
other investments that shall be 

                                     - 2 -
<PAGE>
 
purchased, entered into, sold, closed, or exchanged for the Fund, when these
transactions should be executed, and what portion of the assets of the Fund
should be held in the various securities and other investments in which it may
invest, and the Adviser (or Portfolio Manager) is hereby authorized to execute
and perform such services on behalf of the Fund. To the extent permitted by the
investment policies of the Fund, the Adviser (or Portfolio Manager) shall make
decisions for the Fund as to foreign currency matters and make determinations as
to the retention or disposition of foreign currencies or securities or other
instruments denominated in foreign currencies or derivative instruments based
upon foreign currencies, including forward foreign currency contracts and
options and futures on foreign currencies, and shall execute and perform the
same. The Adviser (or Portfolio Manager) will provide the services under this
Agreement for each Fund in accordance with the Fund's investment objective or
objectives, investment policies, and investment restrictions as stated in the
Trust's Registration Statement filed on Form N-1A with the SEC as supplemented
or amended from time to time.


          In performing these duties, the Adviser, either directly or indirectly
through others selected by the Adviser:

               (a)   Shall conform with the 1940 Act and all rules and
          regulations thereunder, all other applicable federal and state laws
          and regulations, with any applicable procedures adopted by the Trust's
          Board of Trustees, and with the provisions of the Trust's Registration
          Statement filed on Form N-1A as supplemented or amended from time to
          time.


               (b)   Shall use reasonable efforts to manage each Fund so that it
          qualifies as a regulated investment company under Subchapter M of the
          Internal Revenue Code.


               (c)   Is responsible, in connection with its responsibilities
          under this Section 2, for decisions to buy and sell securities and
          other investments for the Funds, for broker-dealer and futures
          commission merchant ("FCM") selection, and for negotiation of
          commission rates. The Adviser's (or Portfolio Manager's) primary
          consideration in effecting a 

                                     - 3 -
<PAGE>
 
          security or other transaction will be to obtain the best execution for
          the Fund, taking into account the factors specified in the Prospectus
          and Statement of Additional Information for the Trust, as they may be
          amended or supplemented from time to time. Subject to such policies as
          the Board of Trustees may determine and consistent with Section 28(e)
          of the Securities Exchange Act of 1934, the Adviser (or Portfolio
          Manager) shall not be deemed to have acted unlawfully or to have
          breached any duty created by this Agreement or otherwise solely by
          reason of its having caused the Fund to pay a broker or dealer, acting
          as agent, for effecting a portfolio transaction at a price in excess
          of the amount of commission another broker or dealer would have
          charged for effecting that transaction, if the Adviser (or Portfolio
          Manager) determines in good faith that such amount of commission was
          reasonable in relation to the value of the brokerage and research
          services provided by such broker or dealer, viewed in terms of either
          that particular transaction or the Adviser's (or Portfolio Manager's)
          overall responsibilities with respect to the Fund and to their other
          clients as to which they exercise investment discretion. To the extent
          consistent with these standards, and in accordance with Section 11(a)
          of the Securities Exchange Act of 1934 and Rule 11a2-(T) thereunder,
          and subject to any other applicable laws and regulations, the Adviser
          (or Portfolio Manager) is further authorized to allocate the orders
          placed by it on behalf of the Fund to the Adviser (or Portfolio
          Manager) if it is registered as a broker or dealer with the SEC, to
          its affiliate that is registered as a broker or dealer with the SEC,
          or to such brokers and dealers that also provide research or
          statistical research and material, or other services to the Fund or
          the Adviser (or Portfolio Manager). Such allocation shall be in such
          amounts and proportions as the Adviser shall determine consistent with
          the above standards, and, upon request, the Adviser will report on
          said allocation regularly to the Board of Trustees of the Trust
          indicating the broker-dealers to which such allocations have been made
          and the basis therefor.


               (d)   May, on occasions when the purchase or sale of a security
          is deemed to be in the best interest of a Fund as well as any other
          investment advisory clients, 

                                     - 4 -
<PAGE>
 
          to the extent permitted by applicable laws and regulations, but shall
          not be obligated to, aggregate the securities to be so sold or
          purchased with those of its other clients where such aggregation is
          not inconsistent with the policies set forth in the Registration
          Statement. In such event, allocation of the securities so purchased or
          sold, as well as the expenses incurred in the transaction, will be
          made by the Adviser (or Portfolio Manager) in a manner that is fair
          and equitable in the judgment of the Adviser (or Portfolio Manager) in
          the exercise of its fiduciary obligations to the Trust and to such
          other clients.


               (e)   Will, in connection with the purchase and sale of
          securities for each Fund, arrange for the transmission to the
          custodian for the Trust on a daily basis, such confirmation, trade
          tickets, and other documents and information, including, but not
          limited to, Cusip, Sedol, or other numbers that identify securities to
          be purchased or sold on behalf of the Fund, as may be reasonably
          necessary to enable the custodian to perform its administrative and
          recordkeeping responsibilities with respect to the Fund, and, with
          respect to portfolio securities to be purchased or sold through the
          Depository Trust Company, will arrange for the automatic transmission
          of the confirmation of such trades to the Trust's custodian.


               (f)   Will make available to the Trust, promptly upon request,

a majority of the outstanding shares of any other Fund or (b) that this
Agreement has not been approved by the vote of a majority of the outstanding

determining the securities and other investments that shall be purchased,
entered into, sold, closed, or exchanged for the Funds, when these transactions
should be executed, and what portion of the assets of the Funds should be held
in the various securities and other investments in which it may invest, and the
Portfolio Manager is hereby authorized to execute and perform such services on
behalf of the Funds.  To the extent permitted by the investment policies of the
Funds, the Portfolio Manager shall make decisions for the Funds as to foreign
currency matters and 

                                     - 2 -

make determinations as to the retention or disposition of foreign currencies or
securities or other instruments denominated in foreign currencies, or derivative
instruments based upon foreign currencies, including forward foreign currency
contracts and options and futures on foreign currencies and shall execute and
perform the same on behalf of each Fund. The Portfolio Manager will provide the
services under this Agreement in accordance with the Funds' investment objective
or objectives, investment policies, and investment restrictions as stated in the
Trust's Registration Statement filed on Form N-1A with the SEC, as supplemented
or amended from time to time, copies of which shall be sent to the Portfolio
Manager by the Adviser. In performing these duties, the Portfolio Manager:


          (a) Shall conform with the 1940 Act and all rules and regulations
          thereunder, all other applicable federal and state laws and
          regulations, with any applicable procedures adopted by the Trust's
          Board of Trustees, and with the provisions of the Trust's Registration
          Statement filed on Form N-1A, as supplemented or amended from time to
          time.


          (b) Shall use reasonable efforts to manage each Fund so that it
          qualifies as a regulated investment company under Subchapter M of the
          Internal Revenue Code.


          (c) Is responsible, in connection with its responsibilities under this
          Section 2, for decisions to buy and sell securities and other
          investments for the Funds, for broker-dealer and futures commission
          merchant ("FCM") selection, and for negotiation of commission rates.
          The Portfolio Manager's primary consideration in effecting a security
          or other transaction will be to obtain the best execution for the
          Funds, taking into account the factors specified in the Prospectus and
          Statement of Additional Information for the Trust, as they may be
          amended or supplemented from time to time.  Subject to such policies
          as the Board of Trustees may determine and consistent with Section
          28(e) of the Securities Exchange Act of 1934, the Portfolio Manager
          shall not be deemed to have acted unlawfully or to have breached any
          duty created by this Agreement or otherwise solely by reason of its
          having caused the Funds to pay a broker or dealer, acting as agent,
          for effecting a portfolio transaction at a price in excess of the
          amount of commission another broker or dealer would have charged for
          effecting that transaction, if 

                                     - 3 -
<PAGE>
 
          the Portfolio Manager determines in good faith that such amount of
          commission was reasonable in relation to the value of the brokerage
          and research services provided by such broker or dealer, viewed in
          terms of either that particular transaction or the Portfolio Manager's
          overall responsibilities with respect to the Funds and to its other
          clients as to which it exercises investment discretion. To the extent
          consistent with these standards, and in accordance with Section 11(a)
          of the Securities Exchange Act of 1934 and Rule 11a2-(T) thereunder,
          and subject to any other applicable laws and regulations, the
          Portfolio Manager is further authorized to allocate the orders placed
          by it on behalf of the Funds to the Portfolio Manager if it is
          registered as a broker or dealer with the SEC, to its affiliate that
          is registered as a broker or dealer with the SEC, or to such brokers
          and dealers that also provide research or statistical research and
          material, or other services to the Funds or the Portfolio Manager.
          Such allocation shall be in such amounts and proportions as the
          Portfolio Manager shall determine consistent with the above standards,
          and, upon request, the Portfolio Manager will report on said
          allocation to the Adviser and Board of Trustees of the Trust,
          indicating the brokers or dealers to which such allocations have been
          made and the basis therefor.


          (d) May, on occasions when the purchase or sale of a security is
          deemed to be in the best interest of a Fund as well as any other
          investment advisory clients, to the extent permitted by applicable
          laws and regulations, but shall not be obligated to, aggregate the
          securities to be so sold or purchased with those of its other clients
          where such aggregation is not inconsistent with the policies set forth
          in the Registration Statement.  In such event, allocation of the
          securities so purchased or sold, as well as the expenses incurred in
          the transaction, will be made by the Portfolio Manager in a manner
          that is fair and equitable in the judgment of the Portfolio Manager in
          the exercise of its fiduciary obligations to the Trust and to such
          other clients.


          (e) Will, in connection with the purchase and sale of securities for
          each Fund, arrange for the transmission to the custodian for the Trust
          on a daily basis, such confirmation, trade tickets, and other
          documents and information, including, but not limited to, Cusip,

                                     - 4 -

          Sedol, or other numbers that identify securities to be purchased or
          sold on behalf of the Fund, as may be reasonably necessary to enable
          the custodian to perform its administrative and recordkeeping
          responsibilities with respect to the Fund, and, with respect to
          portfolio securities to be purchased or sold through the Depository
          Trust Company, will arrange for the automatic transmission of the
          confirmation of such trades to the Trust's custodian.


          (f) The Portfolio Manager will assist the custodian and recordkeeping
          agent(s) for the Trust in determining or confirming, consistent with
          the procedures and policies stated in the Registration Statement for
          the Trust, the value of any portfolio securities or other assets of
          the Fund for which the custodian and recordkeeping agent(s) seek
          assistance from the Portfolio Manager or identify for review by the
          Portfolio Manager.


          (g) Will make available to the Trust and Adviser, promptly upon
          request, any of the Funds' investment records and ledgers as are
          necessary to assist the Trust to comply with requirements of the 1940
          Act and the Investment Advisers Act of 1940, as well as other
          applicable laws, and will furnish to regulatory authorities having the
          requisite authority any information or reports in connection with such
          services which may be requested in order to ascertain whether the
          operations of the Trust are being conducted in a manner consistent
          with applicable laws and regulations.


          (h) Will regularly report to the Trust's Board of Trustees on the
          investment program for each Fund and the issuers and securities
          represented in each Fund's portfolio, and will furnish the Trust's
          Board of Trustees with respect to the Funds such periodic and special
          reports as the Trustees may reasonably request.


          (i)  The Portfolio Manager shall be responsible for making reasonable
          inquiries and for reasonably ensuring that any employee of the
          Portfolio Manager has not, to the best of the Portfolio Manager's
          knowledge:

                                     - 5 -

shares of the Trust, unless such approval shall be required by any other
applicable law or otherwise.  This Agreement will terminate automatically with
respect to the services provided by the Portfolio Manager in event of its
assignment, as that term is defined in the 1940 Act, by the Portfolio Manager.

PIMCO Advisors Distribution Company
2187 Atlantic Avenue
Stamford, Connecticut 06902

Dear Sirs:

     This will confirm the agreement between the undersigned (the "Trust") and
you (the "Distributor") as follows:


     1.  Description of Trust and Classes of Shares.  The Trust is an open-end
investment company which presently has the following [twenty] investment
portfolios: Equity Income Fund, Value Fund, Summit Fund, Enhanced Equity Fund,
Growth Fund, Capital Appreciation Fund, Mid Cap Growth Fund, Target Fund, Small
Cap Value Fund, Small Cap Growth Fund, Opportunity Fund, Micro Cap Growth Fund,
Innovation Fund, International Fund, [New International Fund], Emerging Markets
Fund, Precious Metals Fund, Balanced Fund and Tax Exempt Fund (each a "Fund,"
and collectively, the "Funds").  Additional investment portfolios may be
established in the future.  This Contract shall pertain to the Funds and to such
additional investment portfolios as shall be designated in Supplements to this
Contract, as further agreed between the Trust and the Distributor.  A separate
series of shares of beneficial interest in the Trust is offered to investors
with respect to each Fund, and each Fund currently offers its shares with
respect to five classes: Class A shares, Class B shares, and Class C shares
(together, the "Retail Classes"), and Institutional Class shares and
<PAGE>
 
Administrative Class shares.  The Trust engages in the business of investing and
reinvesting the assets of the Funds in the manner and in accordance with the
investment objective and restrictions specified in the Trust's currently
effective Prospectus or Prospectuses and Statement of Additional Information
(together, the "Prospectus") relating to the Retail, Institutional and
Administrative Classes of the Funds included in the Trust's Registration
Statement, as amended from time to time (the "Registration Statement"), as filed
by the Trust under the Investment Company Act of 1940, as amended (together with
the rules and regulations thereunder, the "1940 Act") and the Securities Act of
1933, as amended (together with the rules and regulations thereunder, the "1933
Act").  Copies of the documents referred to in the preceding sentence have been
furnished to the Distributor.  Any amendments to those documents shall be
furnished to the Distributor promptly.  The Trust has adopted separate
Distribution and Servicing Plans pursuant to Rule 12b-l under the 1940 Act with
respect to each of the Retail Classes (the "Retail Class Plans") and has adopted
a Distribution Plan, also pursuant to Rule 12b-1, with respect to the
Administrative Class shares of the Funds (the "Administrative Distribution
Plan").  The Trust has also adopted an Administrative Services Plan with respect
to the Administrative Class shares of the Funds, in conformity with Rule 12b-1,
as if the expenditures made thereunder were subject to Rule 12b-1, excepting the
shareholder voting rights under Rule 12b-1 (the "Administrative Services Plan,"
and together with the Retail Class Plans and the Administrative Distribution
Plan, the "Plans").

     2.  Appointment and Acceptance.  The Trust hereby appoints the Distributor
as a distributor of shares of beneficial interest in the Trust (the "shares")
which may from time to time be registered under the 1933 Act and as servicing
agent of shareholders and shareholder accounts of the Trust, and the Distributor
hereby accepts such appointment in accordance with the terms and conditions set
forth herein.  As the Trust's agent, the Distributor shall, except to the extent
provided in Section 4 hereof, be the exclusive distributor for the unsold
portion of the shares.

     3.  Sale of Shares to Distributor and Sales by Distributor.  The
Distributor will have the right, as principal, to sell shares of each Class of
each Fund directly to the public against orders therefor at the applicable
public offering price as described below in the case of Class A shares, and at
net asset value in the case of Class B shares, Class C shares, Institutional
Class shares and Administrative Class shares.  For such purposes, the
Distributor will have the right to purchase shares at net asset value.  The
Distributor will also have the right, as agent, to sell shares of a Fund
indirectly to the public through broker dealers who are members of the National
Association of Securities Dealers, Inc. and who are acting as introducing
brokers pursuant to clearing agreements with the Distributor ("introducing
brokers"), to broker dealers which are members of the National Association of
Securities Dealers, Inc. and who have entered into selling agreements with the
Distributor ("participating brokers") or through other financial intermediaries,
in each case against orders therefor.  The price for introducing brokers,
participating brokers and other financial intermediaries shall be, in the case
of Class A shares, the applicable public offering price less a concession to be
determined by the Distributor, which concession will not exceed the amount of
the sales


                                      -2-
<PAGE>
 
charge or underwriting discount, if any, described below and, in the case of
Class B shares, Class C shares, Institutional Class shares and Administrative
Class shares, net asset value.

     The Trust shall sell through the Distributor, as the Trust's agent, shares
to eligible investors as described in the Prospectus.  All orders through the
Distributor shall be subject to acceptance and confirmation by the Trust.  The
Trust shall have the right, at its election, to deliver either shares issued
upon original issue or treasury shares.

     Prior to the time of transfer of any shares by the Trust to, or on the
order of, the Distributor or any introducing broker, participating broker or
other financial intermediary, the Distributor shall pay or cause to be paid to
the Trust or to its order an amount in New York clearing house funds equal to
the applicable net asset value of the shares.  Upon receipt of registration
instructions in proper form, the Distributor will transmit or cause to be
transmitted such instructions to the Trust or its agent for registration of the
shares purchased.

     The public offering price of Class A shares shall be the net asset value of
such shares, plus any applicable sales charge as set forth in the Prospectus.
In no event will any applicable sales charge or underwriting discount exceed the
limitations on permissible sales loads imposed by Section 22(b) of the 1940 Act
and Section 26(d)(1) of Article III of the Rules of Fair Practice of the
National Association of Securities Dealers, Inc., as either or both may be
amended from time to time.
 
     On every sale, the Trust shall receive the net asset value of the shares.
The net asset value of the shares shall be determined in the manner provided in
the Declaration of Trust and By-laws of the Trust as then amended or restated.
In the case of Class A shares, the Distributor may retain so much of any sales
charge or underwriting discount as is not allowed by the Distributor as a
concession to dealers and such sales charge or underwriting discount shall be in
addition to the fee paid to the Distributor in respect of Class A shares as
described in Section 5 hereof.

     4.  Sales of Shares by the Trust.  In addition to sales by the Distributor,
the Trust reserves the right to issue shares at any time directly to its
shareholders as a stock dividend or stock split or to sell shares to its
shareholders or other persons at not less than net asset value to the extent
that the Trust, its officers, or other persons associated with the Trust
participate in the sale, or to the extent that the Trust or the transfer agent
for its shares receive purchase requests for shares.

     5.   Fees.  For its services as servicing agent of a Fund's Class A
shareholders and Class A shareholder accounts, the Trust shall pay the
Distributor on behalf of the Fund a servicing fee at the annual rate of 0.25% of
the Fund's average daily net assets attributable to its Class A shares upon the
terms and conditions set forth in the Distribution and Servicing Plan attached
as Exhibit A hereto, and as amended from time to time, and may retain so much of
any sales charge or underwriting discount as is not allowed by the Distributor
as a


                                      -3-
<PAGE>
 
concession to dealers, and shall receive any contingent deferred sales charge as
provided in Section 8 hereof.

     For its services as distributor of a Fund's Class B and Class C shares and
as servicing agent of Class B and Class C shareholders and Class B and Class C
shareholder accounts, the Trust shall pay the Distributor on behalf of the Fund
a distribution fee at the annual rate of 0.75% of the Fund's average daily net
assets, and a servicing fee at the annual rate of 0.25% of the Fund's average
daily net assets, attributable to the Fund's Class B shares and Class C shares,
respectively, upon the terms and conditions set forth in the relevant
Distribution and Servicing Plans attached as Exhibits B and C hereto, as amended
from time to time, and shall receive any contingent deferred sales charge as
provided in Section 8 hereof.  The respective distribution and servicing fees
shall be accrued daily and paid monthly to the Distributor as soon as
practicable after the end of the calendar month in which they accrue, but in any
event within 5 business days following the last calendar day of each month.

     The Trust shall reimburse the Distributor at an annual rate not to exceed
0.25% of the Fund's average daily net assets attributable to its Administrative
Class shares for payments made by the Distributor to various financial
intermediaries in connection with the distribution of Administrative Class
shares upon the terms and conditions set forth in the Administrative
Distribution Plan set forth as Exhibit D hereto.

     6.  Reservation of Right Not to Sell.  The Trust reserves the right to
refuse at any time or times to sell any of its shares for any reason deemed
adequate by it.

     7.  Use of Sub-Agents; Non-exclusivity.  The Distributor may employ such
sub-agents, including one or more participating brokers or introducing brokers,
for the purposes of selling shares of the Trust as the Distributor, in its sole
discretion, shall deem advisable or desirable.  The Distributor may enter into
similar arrangements with other issuers and, except to the extent necessary to
perform its obligations hereunder, nothing herein shall be deemed to limit or
restrict the right of the Distributor, or any affiliate of the Distributor, or
any employee of the Distributor, to engage in any other business or to devote
time and attention to the management or other aspects of any other business,
whether of a similar or dissimilar nature, or to render services of any kind to
any other corporation, firm, individual or association.

     8.  Repurchase of Shares.  The Distributor will act as agent for the Trust
in connection with the repurchase and redemption of shares by the Trust upon the
terms and conditions set forth in the Prospectus or as the Trust acting through
its Trustees may otherwise direct.  The Distributor may employ such sub-agents,
including one or more participating brokers or introducing brokers, for such
purposes as the Distributor, in its sole discretion, shall deem to be advisable
or desirable.  Any contingent deferred sales charge imposed on repurchases and
redemptions of Class A, Class B and Class C shares upon the terms and conditions
set forth in the Prospectus shall be paid to the Distributor in addition to the
fees with respect to Class A, Class B and Class C shares set forth in Section 5
hereof.  The Trust


                                      -4-
<PAGE>
 
will take such steps as are commercially reasonable to track on a share-by-share
basis the aging of its shares for purposes of calculating any contingent
deferred sales charges and/or distribution fees.

     9.   Basis of Purchases and Sales of Shares.  The Distributor's obligation
to sell shares hereunder shall be on a best efforts basis only and the
Distributor shall not be obligated to sell any specific number of shares.
Shares will be sold by the Distributor only against orders therefor.  The
Distributor will not purchase shares from anyone other than the Trust except in
accordance with Section 8 hereof, and will not take "long" or "short" positions
in shares contrary to any applicable provisions of the Declaration of Trust of
the Trust, as amended or restated from time to time.

     10.  Rules of Securities Associations, etc.  As the Trust's agent, the
Distributor may sell and distribute shares in such manner not inconsistent with
the provisions hereof and the Trust's Prospectus as the Distributor may
determine from time to time.  In this connection, the Distributor shall comply
with all laws, rules and regulations applicable to it, including, without
limiting the generality of the foregoing, all applicable rules or regulations
under the 1940 Act and of any securities association registered under the
Securities Exchange Act of 1934, as amended (together with the rules and
regulations thereunder, the "1934 Act").  The Distributor will conform to the
Rules of Fair Practice of the National Association of Securities Dealers, Inc.
and the securities laws of any jurisdiction in which it sells, directly or
indirectly, any shares.  The Distributor also agrees to furnish to the Trust
sufficient copies of any agreement or plans it intends to use in connection with
any sales of shares in adequate time for the Trust to file and clear them with
the proper authorities before they are put in use, and not to use them until so
filed and cleared.

     11.  Independent Contractor.  The Distributor shall be an independent
contractor and neither the Distributor nor any of its officers or employees as
such, is or shall be an employee of the Trust.  The Distributor is responsible
for its own conduct and the employment, control and conduct of its agents and
employees and for injury to such agents or employees or to others through its
agents or employees.  The Distributor assumes full responsibility for its agents
and employees under applicable statutes and agrees to pay all employer taxes
thereunder.

     12.  Registration and Qualification of Shares.  The Trust agrees to execute
such papers and to do such acts and things as shall from time to time be
reasonably requested by the Distributor for the purpose of qualifying and
maintaining qualification of the shares for sale under the so-called Blue Sky
Laws of any state or for maintaining the registration of each Fund of the Trust
and the Trust under the 1933 Act and the 1940 Act, to the end that there will be
available for sale from time to time such number of shares as the Distributor
may reasonably be expected to sell.  The Trust shall advise the Distributor
promptly of (a) any action of the Securities and Exchange Commission or any
authorities of any state or territory, of which it may be advised, affecting
registration or qualification of the Trust, a Fund or the 


                                      -5-
<PAGE>
 
shares thereof, or rights to offer such shares for sale and (b) the happening of
any event which makes untrue any statement or which requires the making of any
change in the registration statement or Prospectus in order to make the
statements therein not misleading.

     13.  Securities Transactions.  The Trust agrees that the Distributor may
effect a transaction on any national securities exchange of which it is a member
for the account of the Trust and any Fund of the Trust which is permitted by
Section 11(a) of the 1934 Act.

     14.  Expenses.

          (a) The Distributor shall from time to time employ or associate with
it such persons as it believes necessary to assist it in carrying out its
obligations under this Contract. The compensation of such persons shall be paid
by the Distributor.

          (b) The Distributor shall pay all expenses incurred in connection with
its qualification as a dealer or broker under Federal or state law.

          (c) The Distributor will pay all expenses of preparing, printing and
distributing advertising and sales literature as such expenses relate to Retail
Class shares (apart from expenses of registering shares under the 1933 Act and
the 1940 Act and the preparation and printing of prospectuses and reports for
shareholders as required by said Acts and the direct expenses of the issue of
shares, except that the Distributor will pay the cost of the preparation and
printing of prospectuses and shareholders' reports used by it in the sale of
Trust shares).  The Trust may enter into arrangements with affiliates of the
Distributor providing for the payment by such affiliates of some or all of these
expenses as they relate to Institutional and Administrative Class shares.

          (d) The Trust shall pay or cause to be paid all expenses incurred in
connection with (i) the preparation, printing and distribution to shareholders
of the Prospectus and reports and other communications to existing shareholders,
(ii) future registrations of shares under the 1933 Act and the 1940 Act, (iii)
amendments of the Registration Statement subsequent to the initial public
offering of shares, (iv) qualification of shares for sale in jurisdictions
designated by the Distributor, including under the securities or so-called "Blue
Sky" laws of any State, (v) qualification of the Trust as a dealer or broker
under the laws of jurisdictions designated by the Distributor, (vi)
qualification of the Trust as a foreign corporation authorized to do business in
any jurisdiction if the Distributor determines that such qualification is
necessary or desirable for the purpose of facilitating sales of shares,
(vii) maintaining facilities for the issue and transfer of shares, (viii)
supplying information, prices and other data to be furnished by the Trust under
this Contract, (ix) any expenses assumed by the Trust with regard to shares of
each Retail Class of each Fund pursuant to the Retail Class Plan applicable to
that class;  (x) any expenses assumed by the Trust with regard to the
Administrative Class shares of each Fund pursuant to the Administrative
Distribution


                                      -6-
<PAGE>
 
Plan; and (xi) any expenses assumed by the Trust with regard to the
Administrative Class shares of each Fund pursuant to the Administrative Services
Plan.

          (e) The Trust shall pay any original issue taxes or transfer taxes
applicable to the sale or delivery of shares or certificates therefor.

     15.  Indemnification of Distributor.  The Trust shall prepare and furnish
to the Distributor from time to time such number of copies of the most recent
form of the Prospectus filed with the SEC as the Distributor may reasonably
request.  The Trust authorizes the Distributor to use the Prospectus, in the
form furnished to the Distributor from time to time, in connection with the sale
of shares.  The Trust shall indemnify, defend and hold harmless the Distributor,
its officers and trustees and any person who controls the Distributor within the
meaning of the 1933 Act, from and against any and all claims, demands,
liabilities and expenses (including the cost of investigating or defending such
claims, demands or liabilities and any counsel fees incurred in connection
therewith) which the Distributor, its officers and trustees or any such
controlling person may incur under the 1933 Act, the 1940 Act, the common law or
otherwise, arising out of or based upon any alleged untrue statement of a
material fact contained in the Registration Statement or the Prospectus or
arising out of or based upon any alleged omission to state a material fact
required to be stated in either or necessary to make the statements in either
not misleading.  This Contract shall not be construed to protect the Distributor
against any liability to the Trust or its shareholders to which the Distributor
would otherwise be subject by reason of willful misfeasance, bad faith or gross
negligence in the performance of its duties or by reason of its reckless
disregard of its obligations and duties under this Contract.  This indemnity
agreement is expressly conditioned upon the Trust being notified of any action
brought against the Distributor, its officers or directors or any such
controlling person, which notification shall be given by letter or by telegram
addressed to the Trust at its principal office in Newport Beach, California, and
sent to the Trust by the person against whom such action is brought within 10
days after the summons or other first legal process shall have been served.  The
failure to notify the Trust of any such action shall not relieve the Trust from
any liability which it may have to the person against whom such action is
brought by reason of any such alleged untrue statement or omission otherwise
than on account of the indemnity agreement contained in this Section 15. The
Trust shall be entitled to assume the defense of any suit brought to enforce any
such claim, demand or liability, but, in such case, the defense shall be
conducted by counsel chosen by the Trust and approved by the Distributor.  If
the Trust elects to assume the defense of any such suit and retain counsel
approved by the Distributor, the defendant or defendants in such suit shall bear
the fees and expenses of any additional counsel retained by any of them, but in
case the Trust does not elect to assume the defense of any such suit, or in the
case the Distributor does not approve of counsel chosen by the Trust, the Trust
will reimburse the Distributor, its officers and directors or the controlling
person or persons named as defendant or defendants in such suit, for the fees
and expenses of any counsel retained by the Distributor or them.  In addition,
the Distributor shall have the right to employ counsel to represent it, its
officers and directors and any such controlling person who may be subject to
liability arising


                                      -7-
<PAGE>
 
out of any claim in respect of which indemnity may be sought by the Distributor
against the Trust hereunder if in the reasonable judgment of the Distributor it
is advisable for the Distributor, its officers and directors or such controlling
person to be represented by separate counsel, in which event the fees and
expense of such separate counsel shall be borne by the Trust.  This indemnity
agreement and the Trust's representations and warranties in this Contract shall
remain operative and in full force and effect regardless of any investigation
made by or on behalf of the Distributor, its officers and directors or any such
controlling person.  This indemnity agreement shall inure exclusively to the
benefit of the Distributor and its successors, the Distributor's officers and
directors and their respective estates and any such controlling persons and
their successors and estates.  The Trust shall promptly notify the Distributor
of the commencement of any litigation or proceedings against it in connection
with the issue and sale of any shares.

     16.  Indemnification of Trust.  The Distributor agrees to indemnify, defend
and hold harmless the Trust, its officers and trustees and any person who
controls the Trust within the meaning of the 1933 Act, from and against any and
all claims, demands, liabilities and expenses (including the cost of
investigating or defending such claims, demands or liabilities and any counsel
fees incurred in connection therewith) which the Trust, its officers or trustees
or any such controlling person, may incur under the 1933 Act, the 1940 Act, the
common law or otherwise, but only to the extent that such liability or expense
incurred by the Trust, its officers or trustees or such controlling person
resulting from such claims or demands shall arise out of or be based upon (a)
any alleged untrue statement of a material fact contained in information
furnished in writing by the Distributor to the Trust specifically for use in the
Registration Statement or the Prospectus or shall arise out of or be based upon
any alleged omission to state a material fact in connection with such
information required to be stated in the Registration Statement or the
Prospectus or necessary to make such information not misleading, (b) any alleged
act or omission on the Distributor's part as the Trust's agent that has not been
expressly authorized by the Trust in writing, and (c) any claim, action, suit or
proceeding which arises out of or is alleged to arise out of the Distributor's
failure to exercise reasonable care and diligence with respect to its services
rendered in connection with investment, reinvestment, employee benefit and other
plans for shares.  The foregoing rights of indemnification shall be in addition
to any other rights to which the Trust or a trustee may be entitled as a matter
of law.  This indemnity agreement is expressly conditioned upon the Distributor
being notified of any action brought against the Trust, its officers or trustees
or any such controlling person, which notification shall be given by letter or
telegram addressed to the Distributor at its principal office in Stamford,
Connecticut, and sent to the Distributor by the person against whom such action
is brought, within 10 days after the summons or other first legal process shall
have been served.  The failure to notify the Distributor of any such action
shall not relieve the Distributor from any liability which it may have to the
Trust, its officers or trustees or such controlling person by reason of any
alleged misstatement, omission, act or failure on the Distributor's part
otherwise than on account of the indemnity agreement contained in this Section
16.  The Distributor shall have a right to control the defense of such action
with counsel of its own choosing and approved by the Trust if such 


                                      -8-
<PAGE>
 
action is based solely upon such alleged misstatement, omission, act or failure
on the Distributor's part, and in any other event the Trust, its officers and
trustees or such controlling person shall each have the right to participate in
the defense or preparation of the defense of any such action at their own
expense. If the Distributor elects to assume the defense of any such suit and
retain counsel approved by the Trust, the defendant or defendants in such suit
shall bear the fees and expenses of any additional counsel retained by any of
them, but in case the Distributor does not elect to assume the defense of any
such suit, or in the case the Trust does not approve of counsel chosen by the
Distributor, the Distributor will reimburse the Trust, its officers and trustees
or the controlling person or persons named as defendant or defendants in such
suit, for the fees and expenses of any counsel retained by the Trust or them. In
addition, the Trust shall have the right to employ counsel to represent it, its
officers and trustees and any such controlling person who may be subject to
liability arising out of any claim in respect of which indemnity may be sought
by the Trust against the Distributor hereunder if in the reasonable judgment of
the Trust it is advisable for the Trust, its officers and trustees or such
controlling person to be represented by separate counsel, in which event the
fees and expense of such separate counsel shall be borne by the Distributor.
This indemnity agreement and the Distributor's representations and warranties in
this Contract shall remain operative and in full force and effect regardless of
any investigation made by or on behalf of the Trust, its officers and trustees
or any such controlling person. This indemnity agreement shall inure exclusively
to the benefit of the Trust and its successors, the Trust's officers and
trustees and their respective estates and any such controlling persons and their
successors and estates. The Distributor shall promptly notify the Trust of the
commencement of any litigation or proceedings against it in connection with the
issue and sale of any shares.

     17.  Assignment Terminates this Contract; Amendments of this Contract.
This Contract shall automatically terminate, without the payment of any penalty,
in the event of its assignment.  This Contract may be amended only if such
amendment be approved either by action of the Trustees of the Trust or at a
meeting of the shareholders of the Trust by the affirmative vote of a majority
of the outstanding shares of the Trust, and by a majority of the Trustees of the
Trust who are not interested persons of the Trust and who have no direct or
indirect financial interest in the operation of the Plans or this Contract by
vote cast in person at a meeting called for the purpose of voting on such
approval.

     18.  Effective Period and Termination of this Contact.  This Contract shall
take effect upon the date first above written and shall remain in full force and
effect continuously as to a Fund and a class of shares thereof (unless
terminated automatically as set forth in Section 17 hereof) until terminated:

          (a) Either by such Fund or such class or the Distributor by not more
than sixty (60) days' nor less than thirty (30) days' written notice delivered
or mailed by registered mail, postage prepaid, to the other party; or


                                      -9-
<PAGE>
 
          (b) Automatically as to any Fund or class thereof at the close of
     business one year from the date hereof, or upon the expiration of one year
     from the effective date of the last continuance of this Contract, whichever
     is later, if the continuance of this Contract is not specifically approved
     at least annually by the Trustees of the Trust or the shareholders of such
     Fund or such class by the affirmative vote of a majority of the outstanding
     shares of such Fund or such class, and by a majority of the Trustees of the
     Trust who are not interested persons of the Trust and who have no direct or
     indirect financial interest in the operation of the Plans or this Contract
     by vote cast in person at a meeting called for the purpose of voting on
     such approval.

     Action by a Fund or a class thereof under (a) above may be taken either (i)
by vote of the Trustees of the Trust, or (ii) by the affirmative vote of a
majority of the outstanding shares of such Fund or such class.  The requirement
under (b) above that the continuance of this Contract be "specifically approved
at least annually" shall be construed in a manner consistent with the 1940 Act
and the rules and regulations thereunder.

     Termination of this Contract pursuant to this Section 18 shall be without
the payment of any penalty.

     If this Contract is terminated or not renewed with respect to one or more
Funds or classes thereof, it may continue in effect with respect to any Fund or
any class thereof as to which it has not been terminated (or has been renewed).

     19.  Limited Recourse.  The Distributor hereby acknowledges that the
Trust's obligations hereunder with respect to the distribution fee or servicing
fee or contingent deferred sales charges payable with respect to the shares of
any Fund of the Trust or a particular class of shares of a Fund are binding only
on the assets and property belonging to such Fund or allocated to such class.

     20.  Certain Definitions.  For the purposes of this Contract, the
"affirmative vote of a majority of the outstanding shares" means the affirmative
vote, at a duly called and held meeting of shareholders, (a) of the holders of
67% or more of the shares of the Trust, Fund or class, as the case may be,
present (in person or by proxy) and entitled to vote at such meeting, if the
holders of more than 50% of the outstanding shares of the Trust, Fund or class,
as the case may be, entitled to vote at such meeting are present in person or by
proxy, or (b) of the holders of more than 50% of the outstanding shares of the
Trust, Fund or class, as the case may be, entitled to vote at such meeting,
whichever is less.

     For the purposes of this Contract, the terms "interested persons" and
"assignment" shall have the meanings defined in the 1940 Act, subject, however,
to such exemptions as may be granted by the Securities and Exchange Commission
under said Act.  Certain other items used herein that are not otherwise defined
have the meaning given in the Trust's Prospectus or constituent agreements or
documents of the Trust.

                      PIMCO FUNDS:  MULTI-MANAGER SERIES
                               DISTRIBUTION PLAN
                        FOR ADMINISTRATIVE CLASS SHARES


          WHEREAS, PIMCO Funds:  Multi-Manager Series (the "Trust") is
registered as an open-end management investment company under the Investment
Company Act of 1940, as amended (the "1940 Act");

          WHEREAS, the Trust issues shares of beneficial interest ("shares") in
separate series ("Funds"), with each Fund representing interests in a separate
portfolio of securities and other assets;

          WHEREAS, the Trust issues shares of the Funds in separate classes of
shares, one of which is designated the Administrative Class (the "Administrative
Class" shares);

          WHEREAS, certain shareholders of the Trust may require distribution
and related services that are in addition to services required by other
shareholders, and the provision of such services to shareholders requiring these
services may benefit such shareholders and facilitate their ability to invest in
the Funds;

          WHEREAS, issuance of shares of the Funds in a class subject to a fee
for the Funds' cost of providing distribution and related services would
allocate the Funds' expense of rendering such services to the shareholders who
receive such additional services;

          WHEREAS, the Funds with respect to their Administrative Class shares
intend to enter into Distribution Agreements ("Agreements") pursuant to this
Distribution Plan (the "Plan") with various Service Organizations ("Service
Organizations"), either directly or through the Trust's distributor, PIMCO
Advisors Distribution Company (the "Distributor"), pursuant to which the Service
Organization will make available or offer Administrative Class shares of the
Funds for sale to the public and/or provide certain shareholder services to its
customers that invest in the Funds;

          WHEREAS, the Funds have adopted a multiple class plan pursuant to Rule
18f-3 under the 1940 Act to permit the issuance of shares in different classes;

          WHEREAS, the Board of Trustees of the Trust has determined that there
is a reasonable likelihood that the Plan will benefit the Funds and their
shareholders;

          NOW THEREFORE, the Trust hereby adopts this
<PAGE>
 
Distribution Plan on the following terms and conditions:

          1.  The Trust (or the Distributor, acting as agent of the Trust) shall
reimburse a Service Organization with which the Trust (or the Distributor),
regarding the Administrative Class of a Fund, has an Agreement, for costs and
expenses incurred in connection with the distribution and marketing of shares of
that Class and/or the provision of certain shareholder services to its customers
that invest in the Funds, at a rate specified in paragraph 2 below, based upon
the average daily net assets of the Fund attributable to the Administrative
Class.

          2.  Subject to the limitations of applicable law and regulations,
including rules of the National Association of Securities Dealers, Inc.
("NASD"), the Service Organization will be reimbursed quarterly for such costs,
expenses or payments at an annual rate of up to but not more than 0.25% of the
average daily net assets of the Fund attributable to the Administrative Class.
Any expense payable hereunder may be carried forward for reimbursement for up to
twelve months beyond the date in which it is incurred, subject always to the
limit that not more than 0.25% of the average daily net assets attributable to
an Administrative Class may be used in any month to pay expenses pursuant to the
Agreement.  An Administrative Class shall incur no interest or carrying charges
for expenses carried forward.  In the event the Plan is terminated as herein
provided, the Administrative Class shall have no liability for expenses that
were not reimbursed as of the date of termination.

          3.  The payment of fees to a Service Organization is subject to
compliance by the Service Organization with the terms of the Agreement between
the Service Organization and the Trust (or the Distributor).  If an
Administrative Class shareholder ceases to be a client of a Service Organization
that has entered into an Agreement with the Trust (or the Distributor), but
continues to hold Administrative Class shares, the Service Organization will be
entitled to receive a similar payment in respect of the services provided to
such investors, except that the Distributor may determine that the Service
Organization shall no longer be entitled to such payment if the client becomes a
client of another Service Organization that has an Agreement with the Trust (or
the Distributor).  For the purposes of determining the fees payable under the
Plan, the average daily net asset value of the Fund attributable to the
Administrative Class shares shall be computed in the manner specified in the
Trust's Declaration of Trust and current prospectus.

          4.  Services which a Service Organization will provide under an
Agreement may include, but are not limited to, the following functions:  placing
orders directly for the purchase of 

                                     - 2 -
<PAGE>
 
a Fund's shares and tendering a Fund's shares for redemption; engaging in
advertising with respect to a Fund's shares; providing information about the
Funds; providing facilities to answer questions from prospective investors about
the Fund; receiving and answering correspondence, including requests for
prospectuses and statements of additional information; preparing, printing and
delivering prospectuses and shareholder reports to prospective shareholders;
complying with federal and state securities laws pertaining to the sale of
Administrative Class shares; and assisting investors in applying to purchase
Fund shares and selecting dividend and other account options. 

Shareholder services which a Service Organization will provide under an
Agreement may include, but are not limited to, the following functions:
receiving, aggregating and processing shareholder orders; furnishing shareholder
sub-accounting; providing and maintaining elective shareholder services such as
check writing and wire transfer services; providing and maintaining pre-
authorized investment plans; communicating periodically with shareholders;
acting as the sole shareholder of record and nominee for shareholders;
maintaining accounting records for shareholders; answering questions and
handling correspondence from shareholders about their accounts; issuing
confirmations for transactions by shareholders; and performing similar account
administrative services. In addition, Service Organizations can provide their
endorsement of the Administrative Class shares of a Fund to their clients,
members or customers as an inducement to invest in the Fund.

          5.  Any Service Organization entering into an Agreement with a Fund 
(or with the Distributor) under this Plan may also enter into an Administrative
Services Agreement with regard to its Administrative Class with that Fund (or
with the Distributor), pursuant to an Administrative Services Plan adopted by
the Trust, which will not be subject to the terms of this Plan.  However, in the
event the Service Organization enters into both types of agreements, the Service
Organization shall not be eligible to receive fees under more than one agreement
with respect to the same assets.  A Fund (or the Distributor, acting as the
Fund's agent) under this Plan may enter into more than one Distribution
Agreement for its Administrative Class shares, with different Service
Organizations providing services to different groups of shareholders.

          6.  For so long as required pursuant to Rule 12b-1 under the 1940 Act,
the Plan shall not take effect with respect to a Fund until it has been approved
by a vote of at least a majority (as defined in the 1940 Act) of the outstanding
voting securities of the Administrative Class of that Fund, which may include
the vote by an affiliated person of the Fund as the sole shareholder of the
Fund.  With respect to the submission of the 

                                     - 3 -
<PAGE>
 
Plan for such a vote, it shall have been effectively approved with respect to a
Fund if a majority of the outstanding voting securities of the Administrative
Class of the Fund votes for approval of the Plan, notwithstanding that the
matter has not been approved by a majority of the outstanding voting securities
of the Administrative Class of any other Fund.

          7.  The Plan shall not take effect until it has been approved,
together with any related agreements and supplements, by votes of a majority of
both (a) the Board of Trustees of the Trust, and (b) those Trustees of the Trust
who are not "interested persons" (as defined in the 1940 Act) and have no direct
or indirect financial interest in the operation of the Plan or any agreements
related to it (the "Plan Trustees"), cast in person at a meeting (or meetings)
called for the purpose of voting on the Plan and such related agreements.

          8.  The Plan shall continue in effect so long as such continuance is
specifically approved at least annually in the manner provided for approval of
the Plan in paragraph 7.

          9.  Any person authorized to direct the disposition of monies paid or
payable by an Administrative Class pursuant to the Plan or any related agreement
shall provide to the Trust's Board of Trustees, and the Board shall review, at
least quarterly, a written report of the amounts so expended and the purposes
for which such expenditures were made.

          10.  Any agreement related to the Plan, as such phrase is used is Rule
12b-1 under the 1940 Act, shall be in writing and shall provide:  (a) that such
agreement may be terminated at any time as to a Fund, without payment of any
penalty, by vote of a majority of the Plan Trustees or by vote of a majority of
the outstanding voting securities of the Administrative Class of a Fund, on not
more than sixty (60) days' written notice to any other party to the agreement;
and (b) that such agreement shall terminate automatically in the event of its
assignment.

          11.  The Plan may be amended at any time with respect to a Fund by the
Board of Trustees, provided that (a) for so long as required pursuant to Rule
12b-1 under the 1940 Act, any amendment to increase materially the costs which
the Administrative Class shares may bear for distribution pursuant to the Plan
shall be effective only upon approval by a vote of a majority of the outstanding
voting securities of the Administrative Class of the Fund, and (b) any material
amendments of the terms of the Plan shall become effective only upon approval as
provided in paragraph 7 hereof.

          12.  While the Plan is in effect, the selection and 

                                     - 4 -
<PAGE>
 
nomination of Trustees who are not interested persons (as defined in the 1940
Act) of the Trust shall be committed to the discretion of the Trustees who are
not interested persons of the Trust.

          13.  The Trust shall preserve copies of the Plan, any related
agreement and any report made pursuant to paragraph 9 hereof, for a period of
not less than six (6) years from the date of the Plan, such agreement or report,
as the case may be, the first two (2) years of which shall be in an easily
accessible place.

          14.  It is understood and expressly stipulated that neither the
holders of shares of any Fund nor any Trustee, officer, agent or employee of the
Trust shall be personally liable hereunder, nor shall any resort be had to other
private property for the satisfaction of any claim or obligation hereunder, but
the Trust only shall be liable.

          IN WITNESS WHEREOF, the Trust has adopted this Distribution Plan 
effective as of the ______ day of ____________, 199__.

                       PIMCO FUNDS: MULTI-MANAGER SERIES
                 (formerly PIMCO Funds: Equity Advisors Series)

                     AMENDED AND RESTATED MULTI-CLASS PLAN

      Plan pursuant to Rule 18f-3 under the Investment Company Act of 1940
      --------------------------------------------------------------------

                       Effective Date [December 31, 1996]


     WHEREAS, the Board of Trustees of the PIMCO Funds: Multi-Manager Series
(formerly PIMCO Funds: Equity Advisors Series) (the "Trust") have considered the
following Amended and Restated Multi-Class Plan (the "Plan") under which the
Trust may offer multiple classes of shares of its now existing and hereafter
created series pursuant to Rule 18f-3 under the Investment Company Act of 1940,
as amended (the "1940 Act"); and

     WHEREAS, a majority of the Trustees of the Trust and a majority of the
Trustees who are not interested persons of the Trust have found the Plan, as
proposed, to be in the best interests of each class of the Trust individually
and the Trust as a whole;

     NOW, THEREFORE, the Trust hereby approves and adopts the following Plan
pursuant to Rule 18f-3 under the 1940 Act.

1.   FEATURES OF THE CLASSES

     Each now existing and hereafter created series (each a "Fund") of the Trust
is authorized to issue from time to time its shares of beneficial interest in
five classes:  Class A shares, Class B shares, Class C shares, Institutional
Class shares and Administrative Class shares./1/    Each class is subject to
such investment minimums and other conditions of eligibility as are set forth in
the Trust's prospectus(es) as from time to time in effect (together with all
relevant Statements of Additional Information, the "Prospectus").  Each Fund
offers such classes of shares to such classes of persons as are set forth in the
Prospectus.


- ----------------------

     /1/ Currently, Class A and Class C shares of the Trust's Opportunity Fund
are not available for purchase by new investors in that Fund. The Opportunity
Fund has never offered Class B shares. Shareholders who owned shares of the
Opportunity Fund on December 31, 1992 will still be permitted to purchase
additional shares for as long as they continue to own any shares of the Fund.
Similarly, participants in any self-directed qualified benefit plan that owned
Opportunity Fund shares on March 1, 1993 will be eligible to direct the purchase
of Opportunity Fund shares by their plan account for so long as the plan
continues to own shares of the Fund.
<PAGE>
 
     Shares of each class of a Fund shall represent an equal pro rata interest
in such Fund and, generally, shall have identical voting, dividend, liquidation,
and other rights, preferences, powers, restrictions, limitations, qualifications
and terms and conditions, except that: (a) each class shall have a different
designation; (b) each class of shares shall bear any Class Expenses, as defined
in Section 4 below and (c) each class shall have separate voting rights on any
matter submitted to shareholders in which the interests of one class differ from
the interests of any other class and shall have exclusive voting rights on any
matter submitted to shareholders that relates solely to that class.

     In addition, Class A, Class B, Class C, Institutional Class and
Administrative Class shares shall have the features described in Sections 2, 3,
4 and 5 below.  These features are subject to change, to the extent permitted by
law and by the Amended and Restated Declaration of Trust and By-laws of the
Trust, by action of the Board of Trustees of the Trust.

2.   SALES CHARGE STRUCTURE

     (a)  Initial Sales Charge.  Class A shares of the Funds are offered at a
          --------------------                                               
public offering price that is equal to their net asset value ("NAV") plus a
sales charge of up to 5.50% of the public offering price (which maximum may be
less for certain Funds, as described in the Prospectus).  The sales charges on
Class A shares are subject to reduction or waiver as permitted by Rule 22d-1
under the 1940 Act, as described in the Prospectus. For example, as of the date
of this Plan, each Fund may waive the Class A sales charge for certain
categories of investors, including current or retired officers, trustees,
directors or employees of the Trust, and for current registered representatives
and other full-time employees of participating brokers.

     Class B, Class C, Institutional Class and Administrative Class shares of
the Funds are offered at their NAV, without an initial sales charge.

     (b) Contingent Deferred Sales Charge.  A contingent deferred sales charge
         --------------------------------                                     
(a "CDSC") may be imposed on Class A, Class B or Class C shares under certain
circumstances.  The Trust imposes a CDSC on redemptions of a particular class of
shares of a Fund if the investor redeems an amount which causes the current
value of the investor's account for the Fund to fall below the total dollar
amount of purchase payments subject to the CDSC, except that no CDSC is imposed
if the shares redeemed have been acquired through the reinvestment of dividends
or capital gains distributions or if the amount redeemed is derived from
increases in the value of the account above the amount of purchase payments
subject to a CDSC.  In determining whether a CDSC is payable, it is assumed that
the purchase payment from which the redemption is made is the earliest purchase
payment from which a redemption or exchange has not already been effected.  In
determining whether an amount is available for redemption of a certain class
without incurring a CDSC, the purchase payments made for all shares of that
class in the investor's account with the particular Fund are aggregated, and the
current value of all such shares is aggregated.

                                      -2-
<PAGE>
 
     Purchases of Class A shares of each Fund of $1 million or more that are
redeemed within eighteen months of their purchase are subject to a CDSC of 1%,
except that the CDSC on Class A shares does not apply to an investor purchasing
$1 million or more of a Fund's Class A shares if such investor is otherwise
eligible (i.e. without regard to the amount of the purchase) to purchase Class A
shares of such Fund without any sales charge.  The conditions for such
eligibility will be set forth in the Prospectus.

     Class B shares that are redeemed within 6 years from purchase are subject
to a CDSC of up to 5% of the redemption amount to which the CDSC applies; such
percentage declines, eventually to 0%, the longer the shares are held, as
described in the Prospectus.  As of the date of this Plan, purchases of Class B
shares are subject to a CDSC according to the following schedule:

</TABLE>

       * Class B shares convert into Class A shares as described below.


     Class C shares are subject to a CDSC of 1% if redeemed within 1 year after
purchase.

     As permitted by Rule 6c-10 under the 1940 Act and as described in the
Prospectus, the CDSC otherwise applicable to Class A, Class B and Class C shares
is subject to reduction or waiver in connection with particular classes of
transactions provided the conditions in Rule 22d-1 under the 1940 Act are
satisfied. As of the date of this Plan, examples of redemptions for which the
CDSC is not applicable include any partial or complete redemption following
death or disability of a shareholder from an account in which the deceased or
disabled is named, provided the redemption is requested within one year of the
death or initial determination of disability (which applies to all classes), and
any redemption resulting from a return of an excess contribution to a qualified
employer retirement plan or an IRA (which applies only to Class A and Class C
shares).

     Institutional Class and Administrative Class shares of each Fund are not
subject to a CDSC.

3.   SERVICE, DISTRIBUTION AND ADMINISTRATIVE FEES

     (a) Service and Distribution Fees. Class A, Class B and Class C shares
         -----------------------------                                     
pay PIMCO Advisors Distribution Company (the "Distributor") fees for services
rendered and expenses borne in connection with personal services rendered to
shareholders of that class and the maintenance of shareholder accounts ("Service
Fees").  Class A, Class B and Class C shares of each Fund pay a Service Fee of
up to 0.25% per annum of the average daily net assets of such Fund attributable
to such class, as described in the Prospectus.  In addition, Class B and Class C
shares pay the Distributor fees in connection with the distribution of shares of
that class ("Distribution Fees").  Class B and Class C shares of each Fund pay a
Distribution Fee of up to 0.75% per annum of the average daily net assets of
such Fund attributable to such class, as described in the Prospectus.  Class A
Service Fees and Class B and C Distribution and Service Fees ("12b-1 Fees") are
paid pursuant to separate plans adopted for each class pursuant to Rule 12b-1
under the 1940 Act.

     The Trust has not adopted an administrative services plan or a distribution
plan with respect to the Institutional Class shares of the Funds. However,
Institutional Class shares may be offered through certain brokers and financial
intermediaries ("service agents") that have established a shareholder servicing
relationship with the Trust on behalf of their customers. The Trust pays no
compensation to such entities. Service agents may impose additional or different
conditions on the purchase or redemption of Trust shares and may charge
transaction or account fees. Service agents are responsible for transmitting to
their customers a schedule of any such fees and conditions.

     The Trust has adopted an administrative services plan and a distribution
plan with respect to the Administrative Class shares of each Fund. Under the
terms of each plan, the Trust is permitted to reimburse, out of the
Administrative Class assets of each Fund, in an amount up to 0.25% on an annual
basis of the average daily net assets of that class ("Administrative Class
Fees"), financial intermediaries that provide services in connection with the
distribution of shares or administration of plans or programs that use Fund
shares as their funding medium, as described in the Prospectus. The same entity
may not receive both distribution and administrative services fees with respect
to the same assets but, with respect to separate assets, may receive fees under
both a distribution plan and an administrative services plan.

     (b)  Administration Fees.  Each class of shares of a Fund pays an
          -------------------                                         
administration fee ("Administration Fees") to Pacific Investment Management
Company (the "Administrator") pursuant to an administration agreement, which may
be amended from time to time, to provide for such management services as
custody, transfer agency, accounting, legal and printing services.  As of the
date of this Plan, with respect to every Fund except the Metals, International
and Emerging Markets Funds, (i) Class A, Class B and Class C shares pay an
Administration Fee of 0.40% of their respective average daily net asset and (ii)
Institutional Class and Administrative Class shares pay an Administration Fee of
0.25% of their respective

                                      -4-
<PAGE>
 
average daily net asset value.  The classes of shares of the Metals,
International and Emerging Markets Funds pay the following Administration Fees:
<TABLE>

                                 Fees for               Fees for Instit'l Class
          Fund                   Class A, B, C          and Admin. Class

          <S>                    <C>                    <C>
 
          Metals                    0.50%                     0.35%
          International             0.60%                     0.45%
          Emerging Markets          0.65%                     0.50%
 
</TABLE>

4.   ALLOCATION OF INCOME AND EXPENSES

     (a)  Class A, Class B, Class C and Administrative Class shares pay the
expenses associated with their different distribution and shareholder servicing
arrangements.  All classes pay their respective Administration Fees.  Each class
of shares may, at the Trustees' discretion, also pay a different share of other
expenses (together with 12b-1 Fees, Administrative Class Fees and Administration
Fees, "Class Expenses"), not including advisory fees or other expenses related
to the management of the Trust's assets, if these expenses are actually incurred
in a different amount by that class, or if the class receives services of a
different kind or to a different degree than other classes.

     (b)  The gross income of each Fund generally shall be allocated to each
class on the basis of net assets. To the extent practicable, certain expenses
(other than Class Expenses as defined above, which shall be allocated more
specifically) shall be subtracted from the gross income on the basis of the net
assets of each class of the Fund. These expenses include:

             (1)   Expenses incurred by the Trust (including, but not limited
                   to, fees of Trustees, insurance and legal counsel) not
                   attributable to a particular Fund or to a particular class of
                   shares of a Fund ("Corporate Level Expenses"); and

             (2)   Expenses incurred by a Fund not attributable to any
                   particular class of the Fund's shares (for example, advisory
                   fees, custodial fees, or other expenses relating to the
                   management of the Fund's assets) ("Fund Expenses").

     Expenses of a Fund shall be apportioned to each class of shares depending
on the nature of the expense item.  Corporate Level Expenses and Fund Expenses
shall be allocated among the classes of shares based on their relative net asset
values in relation to the net asset value of the Trust.  Approved Class Expenses
shall be allocated to the particular class to which they are attributable.  In
addition, certain expenses may be allocated differently if their method of
imposition changes.  Thus, if a Class Expense can no longer be attributed to a
class, it shall be charged to a Fund for allocation among classes, as determined
by the Board of Trustees. Any additional Class Expenses not specifically
identified above which are subsequently

                                      -5-
<PAGE>
 
identified and determined to be properly allocated to one class of shares shall
not be so allocated until approved by the Board of Trustees of the Trust in
light of the requirements of the 1940 Act and the Internal Revenue Code of 1986,
as amended (the "Code").

5.   EXCHANGE PRIVILEGES

     Except with respect to exchanges for shares of the Opportunity Fund,
shareholders may exchange shares of one class of a Fund at net asset value,
without the imposition of any sales charge or CDSC, for shares of the same class
offered by another Fund or by PIMCO Funds: Pacific Investment Management Series,
a registered investment company advised by the Administrator, provided that the
exchange is made in states where the securities being acquired are properly
registered.  Shareholders of Funds other than the Opportunity Fund are not
permitted to exchange any of their shares for Opportunity Fund shares unless the
shareholders are independently eligible to purchase Opportunity Fund shares as
described in footnote 1 above.  Institutional Class shares of a Fund may be
exchanged for Administrative Class shares offered by any Fund or by PIMCO Funds:
Pacific Investment Management Series, or vice versa, provided that the
Institutional Class or Administrative Class shareholder, as the case may be,
meets the eligibility requirements of the class into which the shareholder seeks
to exchange.

     With respect to Class A, Class B and Class C shares subject to a CDSC, if
less than all of an investment is exchanged out of a Fund, any portion of the
investment attributable to capital appreciation and/or reinvested dividends or
capital gains distributions will be exchanged first, and thereafter any portions
exchanged will be from the earliest investment made in the Fund from which the
exchange was made.

6.   CONVERSION FEATURES

     Class B shares of each Fund automatically convert to Class A shares of the
same Fund after they have been held for 7 years, and thereafter are subject to
the lower fees charged to Class A shares.  In this regard, if there is any
material increase in 12b-1 Fees applicable to Class A shares without the
approval of the Class B shareholders, the Trust will establish a new class of
shares, into which Class B shares would convert, on the same terms as those that
applied to Class A shares before such increase.  No other conversion features
exist between classes of shares of the Funds.

7.   DIVIDENDS/DISTRIBUTIONS

     Each Fund pays out as dividends substantially all of its net investment
income (which comes from dividends and interest it receives from its
investments) and net realized short-term capital gains.

     All dividends and/or distributions will be paid in the form of additional
shares of the

                                      -6-
<PAGE>
 
class of shares of the Fund to which the dividends and/or distributions relate
or, at the election of the shareholder, of another Fund or a series of PIMCO
Funds at net asset value of such Fund or series, unless the shareholder elects
to receive cash.  Dividends paid by each Fund are calculated in the same manner
and at the same time with respect to each class.

8.   WAIVER OR REIMBURSEMENT OF EXPENSES

     Expenses may be waived or reimbursed by any adviser or sub-adviser to the
Trust, by the Trust's underwriter or any other provider of services to the Trust
without the prior approval of the Trust's Board of Trustees.

9.   EFFECTIVENESS OF PLAN

     This Plan shall not take effect until it has been approved by votes of a
majority of both (a) the Trustees of the Trust and (b) the Independent Trustees
and supersedes all previous plans of the Trust adopted pursuant to Rule 18f-3
under the 1940 Act.

10.  MATERIAL MODIFICATIONS

     This Plan may not be amended to modify materially its terms unless such
amendment is approved in the manner provided for initial approval hereof in
section 9 above.

11.  LIMITATION OF LIABILITY

     The Trustees of the Trust and the shareholders of each Fund shall not be
liable for any obligations of the Trust or any Fund under this Plan, and the
Administrator or any other person, in asserting any rights or claims under this
Plan, shall look only to the assets and property of the Trust or such Funds in
settlement of such right or claim, and not to such Trustees or shareholders.

PIMCO Funds: Equity Advisors Series
840 Newport Center Drive
Suite 360
Newport Beach, California  92660

Dear Sirs:

     We have acted as counsel to PIMCO Funds: Equity Advisors Series, a
Massachusetts business trust (the "Trust"), and we have a general familiarity
with the Trust's business operations, practices and procedures.  You have asked
for our opinion regarding the issuance of shares of beneficial interest by the
Trust in connection with the acquisition by the Growth Fund, a series of the
Trust, of the assets of the Columbus Circle Investors Core Equity Fund, a series
of the Trust, and the acquisition by the Target Fund, a series of the Trust, of
the assets of the Columbus Circle Investors Mid Cap Equity Fund, a series of the
Trust, which will be registered on a Form N-14 Registration Statement (the
"Registration Statement") to be filed by the Trust with the Securities and
Exchange Commission.

     We have examined originals or certified copies, or copies otherwise
identified to our satisfaction as being true copies, of various corporate
records of the Trust and such other instruments, documents and records as we
have deemed necessary in order to render this opinion.  We have assumed the
genuineness of all signatures, the authenticity of all documents examined by us
and the correctness of all statements of fact contained in those documents.

     On the basis of the foregoing, we are of the opinion that the shares of
beneficial interest of the Trust being registered under the Securities Act of
1933 in the Registration Statement will be legally and validly issued, fully
paid and non-assessable by the Trust, upon transfer of assets pursuant to the
terms of the Agreement and Plan of Reorganization included in the Registration
Statement.

     We hereby consent to the filing of this opinion with and as part of the
Registration Statement.

                                            Very truly yours,



                                            /s/ Dechert Price & Rhoads

                      PIMCO FUNDS:  MULTI-MANAGER SERIES
                         ADMINISTRATIVE SERVICES PLAN
                        FOR ADMINISTRATIVE CLASS SHARES



          WHEREAS, PIMCO Funds:  Multi-Manager Series (the "Trust") is
registered as an open-end management investment company under the Investment
Company Act of 1940, as amended (the "1940 Act");

          WHEREAS, the Trust issues shares of beneficial interest ("shares") in
separate series ("Funds"), with each Fund representing interests in a separate
portfolio of securities and other assets;

          WHEREAS, the Trust is authorized to issue shares of the Funds in
separate classes of shares, one of which is designated  the Administrative Class
(the "Administrative Class" shares);

          WHEREAS, certain shareholders of the Trust may require administrative,
recordkeeping, and other services that are in addition to services required by
other shareholders, and the provision of such services to shareholders requiring
these services may benefit such shareholders and facilitate their ability to
invest in the Funds;

          WHEREAS, issuance of shares of the Funds in a class subject to a fee
for the Funds' cost of providing administrative, recordkeeping, and shareholder
services would allocate the Funds' expense of rendering such services to the
shareholders who receive such additional services;

          WHEREAS, the Funds with respect to their Administrative Class shares
intend to enter into Administrative Services Agreements ("Agreements") pursuant
to this Administrative Services Plan (the "Plan") with various Service
Organizations ("Service Organizations"), either directly or through the Funds'
principal underwriter, PIMCO Advisors Distribution Company (the "Distributor")
or other agent of the Fund, pursuant to which the Service Organization will
provide certain administrative, recordkeeping and/or shareholder services to its
clients, members or customers who purchase shares of the Administrative Class of
a Fund;

          WHEREAS, the Funds have adopted a multiple class plan pursuant to Rule
18f-3 under the 1940 Act to permit the issuance of shares in different classes;
and

          WHEREAS, the Board of Trustees of the Trust has determined that there
is a reasonable likelihood that the Plan will benefit the Funds and their
shareholders.

          NOW THEREFORE, the Trust hereby adopts this Plan on the 
<PAGE>
 
following terms and conditions:

          1.  The Trust (or the Distributor or other person acting as agent of
the Trust) shall reimburse a Service Organization with which the Trust (or the
Distributor or other agent), regarding the Administrative Class of a Fund, has
an Agreement, for costs and expenses incurred in connection with providing
certain administrative services for shareholders of that Class, at a rate
specified in paragraph 2 below, based upon the average daily net assets of the
Fund attributable to the Administrative Class.

          2.  Subject to the limitations of applicable law and regulations,
including rules of the National Association of Securities Dealers, Inc.
("NASD"), the Service Organization will be reimbursed quarterly for such costs,
expenses or payments at an annual rate of up to but not more than 0.25% of the
average daily net assets of the Fund attributable to the Administrative Class.
Any expense payable hereunder may be carried forward for reimbursement for up to
twelve months beyond the date in which it is incurred, subject always to the
limit that not more than 0.25% of the Fund's average daily net assets
attributable to the Administrative Class may be used in any month to pay
expenses pursuant to the Agreement.  Each Administrative Class shall incur no
interest or carrying charges for expenses carried forward.  In the event the
Plan is terminated as herein provided, the Administrative Class shall have no
liability for expenses that were not reimbursed as of the date of termination.

          3.  The payment of fees to a Service Organization is subject to
compliance by the Service Organization with the terms of the Agreement between
the Service Organization and the Trust (or the Distributor or other agent).  If
an Administrative Class shareholder ceases to be a client of a Service
Organization that has entered into such an Agreement, but continues to hold
Administrative Class shares, the Service Organization will be entitled to
receive a similar payment in respect of the services provided to such investors
and/or the provision of certain shareholder services to its customers that
invest in the Funds.  For the purposes of determining the fees payable under the
Plan, the average daily net asset value of the Fund attributable to the
Administrative Class shares shall be computed in the manner specified in the
Trust's Declaration of Trust and current prospectus.

          4.  Services which a Service Organization will provide under an
Administrative Services Agreement may include, but are not limited to, the
following functions:  receiving, aggregating and processing shareholder orders;
furnishing shareholder sub-accounting; providing and maintaining elective
shareholder 

                                     - 2 -
<PAGE>
 
services such as check writing and wire transfer services; providing and
maintaining pre-authorized investment plans; communicating periodically with
shareholders; acting as the sole shareholder of record and nominee for
shareholders; maintaining accounting records for shareholders; answering
questions and handling correspondence from shareholders about their accounts;
issuing confirmations for transactions by shareholders; and performing similar
account administrative services.

          5.  Any Service Organization entering into an Agreement with the Trust
(or with the Distributor or other agent) under this Plan may also enter into a
Distribution Agreement with regard to the Administrative Class of a Fund
pursuant to a Distribution Plan adopted for such Class.  However, in the event
the Service Organization enters into both types of agreements, the Service
Organization shall not be eligible to receive fees under more than one agreement
with respect to the same assets.  The Trust (or the Distributor or other person,
acting as the Trust's agent) under this Plan may enter into more than one
Administrative Services Agreement for its Administrative Class shares, with
different Service Organizations providing services to different groups of
shareholders.

          6.  The Plan shall not take effect until it has been approved,
together with any related agreements and supplements, by votes of a majority of
both (a) the Board of Trustees of the Trust, and (b) those Trustees of the Trust
who are not "interested persons" (as defined in the 1940 Act) and have no direct
or indirect financial interest in the operation of the Plan or any agreements
related to it (the "Plan Trustees"), cast in person at a meeting (or meetings)
called for the purpose of voting on the Plan and such related agreements.

          7.  The Plan shall continue in effect so long as such continuance is
specifically approved at least annually in the manner provided for approval of
the Plan in paragraph 6.

          8.  Any person authorized to direct the disposition of monies paid or
payable by an Administrative Class pursuant to the Plan or any related agreement
shall provide to the Trust's Board of Trustees, and the Board shall review, at
least quarterly, a written report of the amounts so expended and the purposes
for which such expenditures were made.

          9.  Any agreement related to the Plan shall be in writing and shall
provide:  (a) that such agreement may be terminated at any time as to a Fund,
without payment of any penalty, by vote of a majority of the Plan Trustees, on
not more than sixty (60) days' written notice to any other party to the
agreement; and (b) that such agreement shall terminate 

                                     - 3 -

automatically in the event of its assignment.

          10.  The Plan may be amended at any time with respect to a Fund by the
Board of Trustees, provided that any amendment to increase materially the costs
which the Administrative Class shares may bear for administrative services
pursuant to the Plan shall be effective only upon approval as provided in
paragraph 6 hereof.

          11.  While the Plan is in effect, the selection and nomination of
Trustees who are not interested persons (as defined in the Act) of the Trust
shall be committed to the discretion of the Trustees who are not interested
persons.

          12.  The Trust shall preserve copies of the Plan, any related
agreement and any report made pursuant to paragraph 8 hereof, for a period of
not less than six (6) years from the date of the Plan, such agreement or report,
as the case may be, the first two (2) years of which shall be in an easily
accessible place.

          13.  It is understood and expressly stipulated that neither the
holders of shares of any Fund nor any Trustee, officer, agent or employee of the
Trust shall be personally liable hereunder, nor shall any resort be had to other
private property for the satisfaction of any claim or obligation hereunder, but
the Trust only shall be liable.

          IN WITNESS WHEREOF, the Trust has adopted this amended and restated
Administrative Services Plan effective as of the ______ day of ____________,
199__.
