                                 INTRODUCTION

  This Rule 13e-3 Transaction Statement on Schedule 13E-3 (the "Schedule 13E-
3") is being filed by Pacific Life Insurance Company, a California corporation
("Pacific Life"), Pacific Asset Management LLC, a Delaware limited liability
company ("PAM"), PIMCO Holding LLC, a Delaware limited liability company
("PHLLC"), PIMCO Partners, LLC, a California limited liability company
("PPLLC"), PIMCO Partners, G.P., a California general partnership ("Partners
GP") and PIMCO Advisors Holdings L.P., a Delaware limited partnership (the
"Partnership"), in connection with the acquisition of the Partnership by
Allianz AG through the merger of an indirect subsidiary of Allianz of America,
Inc., a Delaware corporation ("Allianz of America") with the Partnership
pursuant to an Implementation and Merger Agreement, dated October 31, 1999, as
amended, by and among Allianz of America, PAM, the Partnership, PIMCO Advisors
L.P. ("PIMCO Advisors"), PPLLC, PHLLC, Partners GP, and other parties named
therein (the "Merger Agreement"). By filing this Schedule 13E-3, the
signatories do not concede that Rule 13e-3 under the Securities Exchange Act
of 1934 is applicable to the merger or other transactions contemplated by the
Merger Agreement.

  Allianz of America, a subsidiary of Allianz AG, will acquire the Partnership
by merging an indirect subsidiary of Allianz of America into the Partnership,
with the Partnership as the surviving entity. In the merger, all of the
outstanding limited partner and general partner units in the Partnership will
be converted into the right to receive cash in an amount per unit equal to the
Unit Price which will be $38.75, without interest and subject to potential
downward adjustment as described in the Merger Agreement. As a result of the
merger, the Partnership will become an indirect wholly-owned subsidiary of
Allianz of America. Following the merger, all of the equity interests in the
Partnership will be indirectly owned by Allianz of America. The former
unitholders in the Partnership will no longer have an interest in the
Partnership and therefore will not participate in its future earnings and
growth. Additionally, the Partnership's units will no longer trade on the New
York Stock Exchange, price quotations for the units will no longer be
available and the registration of the Partnership's units under the Securities
Exchange Act of 1934 will be terminated.

  Following the merger, subsidiaries of Allianz of America will, in a series
of transactions, acquire substantially all of the remaining interests in PIMCO
Advisors at the Unit Price, other than those interests beneficially owned by
PAM. PAM will retain an investment in PIMCO Advisors through a new general
partner to be formed by PAM and a subsidiary of Allianz of America. As a
result of the transactions, Allianz of America will control PIMCO Advisors,
having acquired approximately 70% of the outstanding partnership interests in
PIMCO Advisors.

  This Schedule 13E-3 is being filed with the Securities and Exchange
Commission concurrently with a preliminary proxy statement filed by the
Partnership pursuant to Regulation 14A under the Securities Exchange Act of
1934, as amended (the "Proxy Statement"). A copy of the Proxy Statement is
attached hereto as Exhibit (d)(1). The following cross reference sheet is
being supplied pursuant to General Instruction F to Schedule 13E-3 and shows
the location in the Proxy Statement of the information required to be included
in this Schedule 13E-3. The information contained in the Proxy Statement,
including all exhibits thereto, is expressly incorporated herein by reference
and the responses to each item are qualified in their entirety by reference to
the information contained in the Proxy Statement and the exhibits thereto.

                          PIMCO ADVISORS HOLDINGS L.P.

                         Special Meeting of Unitholders
                 Merger Proposed -- Your Vote is Very Important

Dear PIMCO Advisors Holdings L.P. Unitholder:

   On behalf of the general partner of PIMCO Advisors Holdings L.P. (the
"Partnership"), I cordially invite you to attend the special meeting of the
unitholders of the Partnership to be held on April 28, 2000 at 9:00 a.m. local
time, at the Four Seasons Hotel, 690 Newport Center Drive, Newport Beach,
California 92660. At the meeting you will be asked to vote upon a proposal to
adopt and approve the Implementation and Merger Agreement, dated as of October
31, 1999, as amended, by and among Allianz of America, Inc., Pacific Asset
Management LLC, the Partnership, PIMCO Advisors L.P., PIMCO Partners, LLC,
PIMCO Holding LLC, PIMCO Partners, G.P., and other parties to the merger
agreement, the resulting merger of an indirect subsidiary of Allianz of America
into the Partnership and the other transactions contemplated by the merger
agreement.

   If the merger agreement, the merger and the other transactions contemplated
by the merger agreement are adopted and approved:

  . the Partnership will be acquired by Allianz of America through a merger
    of an indirect subsidiary of Allianz of America into the Partnership;

  . all of the outstanding units of limited and general partner interest in
    the Partnership will be converted into the right to receive cash in an
    amount equal to $38.75 per unit, without interest and subject to
    potential downward adjustment as described below, resulting in no further
    public ownership of the Partnership; and

  . following the merger, subsidiaries of Allianz of America will, in a
    series of transactions, acquire substantially all of the remaining
    interests in PIMCO Advisors L.P. for the same per unit purchase price you
    are receiving, other than those beneficially owned by Pacific Asset
    Management LLC, one of the two owners of our general partner, which will
    exchange its approximate 30% interest in PIMCO Advisors L.P. for a new
    security representing a fixed return plus a variable return based on the
    operating profits of Pacific Investment Management Company on the terms
    described in the proxy statement.

   The proposed transactions will result in aggregate payments by Allianz of
America and its affiliates of approximately $3.2 billion in cash for the
interests in the Partnership and PIMCO Advisors L.P. reflecting a $4.8 billion
valuation of PIMCO Advisors L.P. The completion of the transactions
contemplated by the merger agreement is dependent on numerous conditions
described in the proxy statement. In particular, Allianz of America is not
obligated to complete the transactions if the revenue
<PAGE>

base of PIMCO Advisors L.P. declines prior to the closing of the transactions,
for reasons other than market movements, to less than 75% of its September 30,
1999 level or if William H. Gross, William S. Thompson and at least 60% of the
other managing directors of Pacific Investment Management Company do not remain
employed by Pacific Investment Management Company.

   The unit price of $38.75 may be reduced if the revenue base of PIMCO
Advisors L.P. decreases, for reasons other than market movements, below 85% of
its September 30, 1999 level. Any reduction would be based on how far revenues
fell below the 85% level; but in no event would you receive less than $31.00
per unit ($31.78 if the settlement of the outstanding unitholder litigation
described in the proxy statement is approved by the court). At January 31,
2000, applicable revenues were at 100.34% of the September level. See the proxy
statement for details.

   On July 6, 1999, the day before the press first reported discussions between
the Partnership and Allianz AG, the parent of Allianz of America, the
Partnership's units of limited partnership interest, which are traded on the
New York Stock Exchange under the symbol "PA", closed at $29.56. On October 4,
1999, the date prior to the announcement by the Partnership of discussions with
Allianz AG, the Partnership units closed at $30.50. On October 29, 1999, the
last trading day prior to the execution of the merger agreement, the
Partnership units closed at $34.69 per unit. On February 10,
2000, the Partnership units closed at $37.81. If the merger agreement, the
merger and the other transactions are approved, the Partnership units will no
longer be traded on the New York Stock Exchange.

   The proxy statement gives you detailed information about the proposed
transactions and includes the merger agreement as an appendix. You can also get
information about the Partnership from publicly available documents we have
filed with the SEC. We encourage you to read carefully this entire document,
including its appendices.

   After careful consideration, PIMCO Partners, G.P., our general partner, has
determined that the merger agreement, the merger of an indirect subsidiary of
Allianz of America into the Partnership and the other transactions contemplated
by the merger agreement are in the best interests of the Partnership and its
unitholders and recommends that you vote "FOR" the merger agreement, the merger
and the other transactions contemplated by the merger agreement. In coming to
this determination, our general partner considered the opinion of our financial
advisor Salomon Smith Barney Inc., dated October 29, 1999, that the
consideration to be received by you pursuant to the merger agreement and in the
merger was fair to you from a financial point of view as of the date of that
opinion. A copy of the written opinion of our financial advisor is attached to
the proxy statement as Appendix B, and you should read it carefully and in its
entirety. The opinion of Salomon Smith Barney is dated October 29, 1999 and
opines as to the fairness as of that date only. Salomon Smith Barney is not
obligated to update its opinion. Events could occur prior to the date of the
special meeting which could result in a different valuation or conclusion if
the opinion was reissued on that date. In the event that there are material
changes to the terms of the proposed transactions or other material changes or
conditions affecting the Partnership or its business, our general partner will
consider the advisability of requesting an updated fairness opinion at that
time. As of the date of this proxy statement, the general partner does not
believe any such material changes have occurred.

   You should be aware that our general partner and its affiliates have
conflicts of interest in the proposed transactions which include:

  .  Pacific Asset Management LLC, one of the owners of our general partner,
     will not sell its approximate 30% interest in PIMCO Advisors L.P. to
     Allianz AG. Instead, it will exchange
<PAGE>

     its interest for a new security described in the proxy statement which
     will be subject to put and call rights which may result in a future sale
     of such interest to Allianz of America; and

  .  certain members of PIMCO Partners, LLC, the other owner of our general
     partner, are also the managing directors of Pacific Investment
     Management Company and will receive employment-related compensation in
     the aggregate, of up to $492.5 million in cash and Allianz AG stock,
     payable over a five year period contingent on continued employment, as
     well as closing payments of approximately $703.3 million in cash and
     Allianz AG stock in settlement of pre-existing unit-based entitlements,
     assuming a unit price of $38.75 and a per share value of Allianz AG
     stock of $273.99, the average trading price for such stock for the 30
     days prior to the public announcement of discussions between Allianz AG
     and PIMCO Advisors. As of March 2, 2000, the closing price of the
     Allianz AG stock was $346.94 per share, increasing the value of the
     payments described above to $505.8 million and $729.9 million,
     respectively. See pages 66 to 74 of the proxy statement for detailed
     information regarding benefits to be received by these persons.

   Our executive officers will also receive significant employment-related
compensation and payments in satisfaction of pre-existing unit based
entitlements as a result of the transactions in the aggregate, of up to $39.3
million contingent on continued employment. In addition, Pacific Asset
Management LLC's ultimate parent corporation is having discussions with Allianz
AG about possibly being acquired by Allianz AG.

   The Partnership's partnership agreement provides that the general partner
may resolve all conflicts of interest in good faith and may rely on a fairness
opinion and other expert opinions in doing so. Having received the fairness
opinion described above and taking into account the other matters described in
the proxy statement, in approving the proposed transaction the general partner
did not retain an independent and disinterested third party to represent the
unaffiliated unitholders.

   YOUR VOTE IS VERY IMPORTANT. The merger and the other transactions
contemplated by the merger agreement cannot be completed without the approval
of the holders of a majority of the units outstanding as of the record date
established by our general partner. We are inviting you, as a unitholder of the
Partnership, to vote on the merger agreement, the merger and the other
transactions contemplated by the merger agreement and to attend a special
meeting of our unitholders if you would like to vote in person. Whether or not
you plan to attend the special meeting, please take the time to vote by
completing and mailing the enclosed proxy card to us at the address set forth
in the proxy statement.

   If you are a registered holder of Partnership units, you are encouraged to
vote by telephone by calling (800) 840-1208 or to vote on the Internet by
visiting the website listed on your proxy card, www.eproxy.com/pa, and
following the instructions on the website. Certain holders who hold their
Partnership units through a bank or broker may also vote using the telephone or
Internet by dialing the toll free number or visiting the Internet website
address printed on your voting form supplied by your bank or broker.

   Please call our investor relations department at (877) 407-7699 or our proxy
solicitor, D.F. King & Co., Inc., toll free at (800) 207-2872 if you have any
questions or need assistance with the voting procedures.

   If you date and mail your proxy card without indicating how you want to
vote, your proxy will be counted as a vote "FOR" the merger agreement, the
merger and the other transactions
<PAGE>

contemplated by the merger agreement. If you abstain or if you do not instruct
your broker how to vote any units held for you in "street name," the effect
will be a vote against the merger agreement, the merger and the other
transactions contemplated by the merger agreement.

                    QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: What am I being asked to vote upon?

A: You are being asked to vote to adopt and approve the merger agreement, the
   acquisition of the Partnership by Allianz of America through a merger of an
   indirect subsidiary of Allianz of America into the Partnership and the
   other transactions contemplated by the merger agreement.

   If the merger is completed, each of your units of limited partnership
   interest will be converted into the right to receive a cash payment and you
   will have no ongoing ownership stake in the continuing business of the
   Partnership, which will survive as an indirect subsidiary of Allianz of
   America. In the merger, you will be entitled to receive $38.75 in cash for
   each unit you own, without interest and subject to potential downward
   adjustment. In no event will you receive less than $31.00 per unit ($31.78
   per unit if the settlement of outstanding unitholder litigation described
   in the proxy statement is approved by the court).

   Following the merger, subsidiaries of Allianz of America will acquire
   substantially all of the remaining interests in PIMCO Advisors L.P. at the
   same per unit purchase price you are receiving, other than the interests
   beneficially owned by Pacific Asset Management LLC, which will exchange its
   approximate 30% interest in PIMCO Advisors L.P. for a new security
   representing a fixed return plus a variable return based on the operating
   profits of Pacific Investment Management Company. The new security being
   received by Pacific Asset Management LLC will be subject to put and call
   rights which may result in a future sale of such interest to Allianz of
   America.

   PIMCO Advisors L.P. is the operating partnership of which the Partnership
   owns approximately 44% as a general partner. As a result of the
   transactions contemplated by the merger agreement, Allianz of America will
   control PIMCO Advisors L.P., having acquired approximately 70% of the
   currently outstanding partnership interests of PIMCO Advisors L.P.

Q: Why is the General Partner recommending the sale of the Partnership to
   Allianz of America?

A: Our general partner has determined that the merger agreement, the merger
   and the other transactions contemplated by the merger agreement are
   advisable, fair to you, and in your best interests, and our general partner
   recommends that you vote to adopt and approve the merger agreement, the
   merger and the other transactions contemplated by the merger agreement. In
   reaching these conclusions we were influenced by several factors,
   including:

  .  The price to be paid per unit which represents a 30% premium over the
     200-day moving average of the closing price of the Partnership's units
     prior to July 7, 1999 ($29.80), the day the press first reported
     discussions between PIMCO Advisors L.P. and Allianz AG. We believe that
     if the merger is not completed, absent other factors, the Partnership's
     unit trading price will revert back to its historical range.

  .  Our belief that long-term success in the investment management business
     requires significant global growth and presence, particularly in Europe.
     Due in part to the significant costs required to establish a substantial
     foreign presence, we do not believe we are likely to achieve this in the
     near term through internal growth. After investigating a number of
     alternatives which did not involve a sale of the business, we concluded
     that the acquisition proposed by Allianz of America produced the best
     value to our unitholders.

                                       1
<PAGE>

  .  The trends in the equity markets since 1997, which have favored growth
     and index strategies and disfavored value strategies. These trends have
     resulted in significant net asset outflows from our value managers. Our
     value managers accounted for approximately 34.1% of our total revenues
     from portfolio management in 1998 and approximately 27.7% of our total
     revenues from portfolio management in 1999.

  .  The opinion of Salomon Smith Barney stating that, as of October 29,
     1999, and based upon and subject to the factors and assumptions set
     forth in the opinion, the consideration to be received by you was fair
     to you from a financial point of view, and the opinion of McLagan
     Partners, Inc., a compensation consultant, stating that, subject to the
     factors and assumptions set forth in the opinion, the retention
     incentive arrangements being provided to executives of Pacific
     Investment Management Company under the merger agreement were
     reasonable.

Q: What will I receive if the merger agreement is approved?

A: Each Partnership unit that you own as of the date of the merger will be
   converted into the right to receive cash in the amount of $38.75, without
   interest and subject to potential downward adjustment as described in next
   paragraph.

Q: Under what circumstances could I receive less than $38.75 per unit?

A: You will receive less than $38.75 per unit only if the revenue base of PIMCO
   Advisors L.P. declines by the last calendar month-end prior to the closing
   date of the merger, for reasons other than market movements, to less than
   85% of its September 30, 1999 level. In that event, the amount you receive
   per unit would be reduced by 2% for each 1% this amount falls below the 85%
   threshold, subject to a maximum reduction of 20%. If the settlement of the
   unitholder litigation described in this proxy statement is approved by the
   court, then the adjustment to the unit price for your units will be reduced
   to 1.8% for each 1% decline below the 85% threshold, with a maximum
   reduction of 18%. In no event will you receive less than $31.00 per unit
   ($31.78 if the settlement is approved) if the merger is approved and
   consummated.

   There will be no downward adjustment to the $38.75 unit price in the merger
   unless we experience net outflows of assets far in excess of any we have
   experienced in the past. Our baseline September 30, 1999 revenue base was
   $780.8 million. On January 31, 2000 our revenue base was $783.5 million
   representing 100.34% of its September 30, 1999 level.

Q: Who is Allianz of America?

A: Allianz of America is a holding company that owns several insurance and
   financial services companies and is a subsidiary of Allianz AG. Allianz AG
   and its subsidiaries comprise the world's second largest insurance group as
   measured by premium income.

Q: When do you expect the merger to be completed?

A: We are working toward completing the merger as quickly as possible. We must
   obtain unitholder, client and regulatory approvals first, and hope to
   complete the merger as soon as possible after the special meeting.

Q: When and where is the special meeting?

A: The special meeting will take place at the Four Seasons Hotel, 690 Newport
   Center Drive, Newport Beach, California 92660, on April 28, 2000 at 9:00
   a.m. local time.

Q: What do I need to do now?

A: We urge you to read this proxy statement carefully, including its
   appendices, and to consider how the merger affects you as a unitholder. You
   also may want to review the documents referenced under "Where You Can Find
   More Information" on page 104.

Q: How do I vote?

A: You can vote in one of the following ways.

  .  Indicate on your proxy card how you want to vote, and sign and mail your
     proxy card in the enclosed return envelope as soon as possible so that
     your units will be represented at the special meeting. If you sign and
     send in your proxy and do not indicate how you want to vote, your proxy
     will be counted as a vote for the merger and the merger agreement,
     unless your units are held in a brokerage account.

  .  If you are a registered holder of Partnership units, call (800) 840-
     1208, toll-free and vote by telephone, or visit the website
     www.eproxy.com/pa and vote on the Internet.

  .  If you hold your Partnership units through a bank or broker you may vote
     by telephone or over the Internet at the telephone number or Internet
     website printed on your voting card provided by your bank or broker.

  .  Attend the special meeting and complete a ballot at that time.

Q: If my units are held in "street name" by my broker, will my broker vote my
   units for me?

A: Your broker will not vote your units for you unless you provide
   instructions on how to vote. It is important therefore that you follow the
   directions provided by your broker regarding how to instruct your broker to
   vote your units. Because holders of a majority of the outstanding units
   must adopt and approve the merger agreement, the merger and the other
   transactions, broker non-votes will have the same effect as votes against
   approval of the merger and the merger agreement.

Q: May I change my vote?

A: Yes. You may change your vote at any time before your proxy is voted at the
   special meeting. You may do this in one of three ways. First, you may send
   a written notice stating that you would like to revoke your proxy. Second,
   you may complete and submit a new proxy card. If you choose either of these
   two methods, you must submit your notice of revocation or your new proxy
   card to us at the principal office of the Partnership. Third, you may
   attend the special meeting and vote in person. Simply attending the special
   meeting, without voting in person, will not revoke your proxy. If you have
   instructed a broker to vote your units, you must follow directions received
   from your broker to change your vote or to vote at the special meeting.

Q: Should I send in my unit certificates now?

A: No. After the merger is completed, we will send you written instructions
   for receiving your cash payment in exchange for your units.

                                       3
<PAGE>


Q:  What are the tax consequences of the merger to me?

A:  In general, upon conversion of your Partnership units into cash pursuant to
    the merger, you will recognize gain or loss for tax purposes equal to the
    difference between the amount of cash received (plus your share of the
    Partnership's liabilities, if any) and your adjusted tax basis in your
    Partnership units. Such gain or loss will generally be capital gain or
    loss, except that you will recognize ordinary income to the extent any cash
    received is attributable to tax deductions previously allocated to you
    relating to goodwill and certain other Partnership assets.

Q:  Who can help answer my questions?

A:  If you would like additional copies of this proxy statement or if you have
    questions about the merger agreement, the merger and the other transactions
    contemplated by the merger agreement, including how to complete and return
    your proxy card or how to vote by telephone or on the Internet or would

   This summary highlights selected information from this proxy statement and
may not contain all of the information that is important to you. To understand
fully the transactions contemplated by the merger agreement and for a more
complete description of the legal terms of the transactions, you should read
carefully this entire document and the documents to which we refer you in this
proxy statement. See "Where You Can Find More Information" on page 104.

The Transactions

   The Implementation and Merger Agreement, dated as of October 31, 1999, as
amended, by and among Allianz of America, Inc., Pacific Asset Management LLC
("PAM"), PIMCO Advisors Holdings L.P. (the "Partnership"), PIMCO Advisors L.P.
("PIMCO Advisors"), PIMCO Partners, LLC ("Partners LLC"), PIMCO Holding LLC
("PHLLC"), PIMCO Partners, G.P. ("Partners GP"), and other parties to the
merger agreement provides for the acquisition of the Partnership by Allianz of
America through a merger of an indirect subsidiary of Allianz of America into
the Partnership. In the merger, all of the outstanding units of limited and
general partner interest in the Partnership will be converted into the right to
receive cash in an amount equal to $38.75 per unit, without interest and
subject to potential downward adjustment (the "Unit Price"). As a result of the
merger, the Partnership will become an indirect wholly-owned subsidiary of
Allianz of America and you will have no ongoing stake in the continuing
business of the Partnership.

   Following the merger, subsidiaries of Allianz of America will, in a series
of transactions, acquire substantially all of the remaining interests in PIMCO
Advisors at the same per unit purchase price you are receiving, other than
those beneficially owned by PAM, which will exchange its approximate 30%
interest in PIMCO Advisors for a new security representing a fixed return plus
a variable return based on the operating profits of Pacific Investment
Management Company on the terms described in this proxy statement. PIMCO
Advisors is the operating partnership of which the Partnership owns
approximately 44% as a general partner. As a result of the transactions,
Allianz of America will control PIMCO Advisors, having acquired approximately
70% of the currently outstanding partnership interests of PIMCO Advisors.

   As described more fully below, the unit price of $38.75 may be reduced if
PIMCO Advisors' revenue base decreases, for reasons other than market
movements, below 85% of its September 30, 1999 level. Any reduction would be
based on how far revenues fell below the 85% level; but in no event would you
receive less than $31.00 per unit ($31.78 if the settlement of the outstanding
unitholder litigation is approved by the court). At January 31, 2000,
applicable revenues were at 100.34% of the September level.

   See "The Transaction" for a more detailed discussion of the proposed
transactions, including charts which illustrate the various steps of the
proposed transactions.

Our General Partner's Recommendation

   Our general partner has determined that the merger agreement, the merger and
the other transactions contemplated by the merger agreement are advisable, fair
to you, and in your best interests, and our general partner recommends that you
vote to adopt and approve the merger

                                       5
<PAGE>


agreement, the merger and the other transactions contemplated by the merger
agreement. In reaching these conclusions our general partner was influenced by
several factors, including:

  .  The price being paid per unit which represents a 30% premium over the
     200-day moving average of the closing price of the Partnership units
     prior to July 7, 1999 ($29.80), the day the press first reported
     discussions between PIMCO Advisors and Allianz AG. We believe that if
     the merger is not completed, absent other factors, the Partnership's
     unit trading price will revert back to its historical range.

  .  Our belief that long-term success in the investment management business
     requires significant global growth and presence, particularly in Europe.
     Due in part to the significant costs required to establish a substantial
     foreign presence, we do not believe this is likely to be achieved in the
     near term through internal growth. After investigating a number of
     alternatives which did not involve a sale of the Partnership, we
     concluded that the acquisition proposed by Allianz of America produced
     the best value to our unitholders.

  .  The trends in the equity markets since 1997, which have favored growth
     and index strategies and disfavored value strategies. These trends have
     resulted in significant net asset outflows from our value managers. Our
     value managers accounted for approximately 34.1% of our total revenues
     from portfolio management in 1998 and approximately 27.7% of our total
     revenues from portfolio management in 1999.

  .  The opinion of Salomon Smith Barney stating, among other things, that,
     as of October 29, 1999, and based upon and subject to the factors and
     assumptions set forth in the opinion, the consideration to be received
     by you was fair to you from a financial point of view, and the opinion
     of McLagan Partners, Inc., a compensation consultant, stating that,
     subject to the factors and assumptions set forth in the opinion, the
     retention incentive arrangements being provided to executives of Pacific
     Investment Management Company under the merger agreement were
     reasonable.

Date, Time and Place

   The special meeting of the unitholders of the Partnership will be held at
9:00 a.m. local time on April 28, 2000, at the Four Seasons Hotel, 690 Newport
Center Drive, Newport Beach, California 92660.

Purpose of the Special Meeting

   At the special meeting, you and our other unitholders will consider and vote
on the proposal to adopt and approve the merger agreement attached to this
proxy statement as Appendix A, the merger of the Partnership, the other
transactions contemplated by the merger agreement and any other matters
properly presented for a vote.

Record Date and Quorum

   We have fixed the close of business on February 29, 2000 as the record date
for the determination of unitholders entitled to notice of, and to vote at, the
special meeting and any adjournment of the special meeting. Each unitholder of
record as of the record date will be entitled to one vote for each unit then
owned. As of the record date, there were 50,060,365 Partnership units
outstanding, held of record by approximately 1,530 registered holders. The
holders of a majority of outstanding Partnership units must be present in
person or represented by proxy to constitute a quorum.

                                       6
<PAGE>


Vote Required

   The affirmative vote of the holders of a majority of the Partnership units
outstanding on the record date is required to adopt and approve the merger
agreement, the merger of the indirect subsidiary of Allianz of America into the
Partnership and the other transactions contemplated by the merger agreement.
Properly signed and dated proxies, including those given over the telephone or
Internet, that do not include voting instructions will be voted "FOR" the
merger agreement, the merger and the other transactions contemplated by the
merger agreement. Because the affirmative vote of a majority of the outstanding
Partnership units is required for approval, properly signed and dated proxies,
including those given over the telephone or Internet, marked "ABSTAIN" and
broker non-votes will have the same effect as votes against adoption and
approval of the merger agreement, the merger and the other transactions
contemplated by the merger agreement.

Parties to the Merger

   The Partnership

   The Partnership is a publicly traded Delaware limited partnership owned .01%
by its general partner, PIMCO Partners, G.P., and 99.99% by its public limited
partners. The Partnership's primary source of income is its proportionate share
of the net income of PIMCO Advisors. As of January 31, 2000, the Partnership
held approximately 50 million general partner units of PIMCO Advisors,
representing an approximate 44% general partner interest in PIMCO Advisors.
PIMCO Partners, G.P. and other private holders hold the remaining interests in
PIMCO Advisors.

   Allianz of America

   The limited partnership that will merge with the Partnership is an indirect
subsidiary of Allianz of America. Allianz of America is a holding company that
owns several insurance and financial service companies, including Fireman's
Fund Insurance Company. Allianz of America is a Delaware corporation, and its
principal offices are located at 55 Greens Farms Road, P.O. Box 5160, Westport,
Connecticut 06881. Its telephone number is (203) 221-8500.

   Allianz of America is a subsidiary of Allianz AG. Allianz AG and its
subsidiaries comprise the world's second largest insurance group as measured by
premium income and are leading providers of financial services, particularly in
Europe. Allianz AG has guaranteed the obligations of Allianz of America and its
affiliates under the merger agreement.

The Merger Agreement and the Merger

   The merger agreement is attached to this proxy statement as Appendix A.
Please read the merger agreement carefully and in its entirety. It is the legal
document that governs the merger.

Effective Date of the Merger

   The merger will become effective at the time and date specified in the
certificate of merger to be filed with the Secretary of State of the State of
Delaware pursuant to the Delaware Revised Uniform Limited Partnership Act. We
expect such filing and effective time to occur as soon as practicable after the
special meeting, subject to adoption and approval of the merger agreement, the
merger and the other transactions contemplated by the merger agreement at the
special meeting and the satisfaction or waiver of the other conditions to
completing the transactions provided in the merger agreement.

                                       7
<PAGE>


   An exchange agent will forward to you detailed instructions with regard to
the surrender of certificates, together with a letter of transmittal, as soon
as reasonably practicable following the closing of the merger. You should not
submit your certificates to the exchange agent until you have received these
materials. Payment for units will be made to you as promptly as practicable
following the determination of the merger consideration and receipt by the
exchange agent of your certificates and other required documents. No interest
will be paid or accrued on the cash payable upon the surrender of certificates.

Opinion of Our Financial Advisor

   We retained Salomon Smith Barney to act as a financial advisor in connection
with the merger and the merger agreement to render its opinion as to the
fairness from a financial point of view of the consideration to be received by
you under the merger agreement. Salomon Smith Barney provided an opinion, dated
October 29, 1999, stating that, as of that date and based upon and subject to
the factors and assumptions set forth in the opinion, the consideration to be
received by you in the merger was fair from a financial point of view to you,
taking into consideration the terms of the transactions, including the
arrangements with respect to PAM's continuing ownership interest in PIMCO
Advisors following the closing of the transactions and the retention and
incentive arrangements to be entered into with management. In its analysis,
Salomon Smith Barney made numerous assumptions with respect to the Partnership
and PIMCO Advisors. Such assumptions and estimates contained in Salomon Smith
Barney's analysis and the valuation ranges resulting from any particular
analysis are not necessarily indicative of actual values or predictive of
future results or values, which may be significantly more or less favorable
than those suggested by such analysis. The opinion of Salomon Smith Barney is
dated October 29, 1999, and opines as to the fairness as of that date only.
Salomon Smith Barney is not obligated to update its opinion. Events could occur
prior to the date of the special meeting which could result in a different
valuation or conclusion if the opinion was reissued on that date. In the event
that there are material changes to the terms of the proposed transactions or
other material changes or conditions affecting the Partnership or its business,
our general partner will consider the advisability of requesting an updated
fairness opinion at that time. As of the date of this proxy statement, the
general partner does not believe any such material changes have occurred.

   Salomon Smith Barney has received $2 million in exchange for its services.
The full text of the written opinion of Salomon Smith Barney, which sets forth
a description of assumptions made, matters considered and limitations on its
review, is attached as Appendix B to this proxy statement. You are urged to
read this opinion carefully in its entirety.

Other Information Considered

   In connection with the transactions contemplated by the merger agreement,
Partners LLC also considered analyses performed by Lazard Freres & Co. LLC and
PAM's corporate parent considered the opinion of Goldman Sachs & Co. described
below.

   Lazard Freres. Lazard Freres was retained by the Partnership to assist in
the structuring and analysis of the proposed transactions. It made a series of
presentations to Partnership management and members of Partners LLC which
provided financial and comparative analysis as the transactions

                                       8
<PAGE>

evolved. Lazard Freres was not requested to and did not render an opinion,
appraisal or report with respect to the fairness of the proposed transactions.
In exchange for its services, Lazard Freres will receive $9.2 million if the
proposed transactions are consummated, of which a non-refundable retainer of
$950,000 has already been paid.

   Opinion of Financial Advisor to Pacific Life. Goldman Sachs was retained by
Pacific Life Insurance Company ("Pacific Life"), the direct parent corporation
of PAM, to act as its financial advisor in connection with the proposed
transactions and to evaluate the fairness, from a financial point of view, to
Pacific Life of the consideration to be received by Pacific Life pursuant to
the merger and related exchange transaction. The opinion of Goldman Sachs and
the related financial
analyses are described under the caption "Opinion of Financial Advisor to
Pacific Life." Also more fully described under that caption is the compensation
to be received by Goldman Sachs in exchange for the services provided to
Pacific Life, which includes a retainer of $1 million and a fee of $500,000
upon rendering the opinion to Pacific Life described in this proxy statement.

Financial Interests of Certain Persons in the Transaction

   In considering the recommendation of our general partner with respect to the
merger and the merger agreement, you should be aware that PHLLC and Partners
LLC, the two general partners of our general partner, and their members have
conflicts of interests in the proposed transactions including:

  .  PAM (PHLLC's parent company) will not sell its approximate 30% interest
     in PIMCO Advisors to Allianz of America Instead, it will exchange its
     interest for a new security representing a fixed return plus a variable
     return based on operating profits of Pacific Investment Management
     Company. The new security will be subject to put and call rights which
     may result in a future sale of that interest to Allianz of America; and

  .  certain members of Partners LLC, the managing directors of Pacific
     Investment Management Company, will receive employment-related
     compensation in the aggregate, of up to $442.5 million in cash payments
     and up to 182,488 shares of Allianz AG stock with an assumed value of
     $50.0 million, over a five year period contingent on continued
     employment, as well as aggregate closing payments of approximately
     $603.3 million in cash and approximately 364,977 shares of Allianz AG
     stock with an assumed value of $100.0 million in settlement of pre-
     existing unit-based entitlements (certain employment termination
     agreements entered into in 1994 and outstanding unit options), as a
     result of the transactions, assuming a unit price of $38.75 and a per
     share value of Allianz AG stock of $273.99, the average trading price
     for such stock for the 30 days prior to the public announcement of
     discussions between Allianz AG and PIMCO Advisors. As of March 2, 2000,
     the closing price of the Allianz AG stock was $346.94 per share,
     increasing the payments in stock referenced above to $63.3 million and
     $126.6 million, respectively.

   In addition, our executive officers will receive significant employment-
related compensation and payments in satisfaction of pre-existing unit based
entitlements as a result of the transactions in the aggregate, of up to $39.3
million contingent on continued employment, which presents them with actual and
potential conflicts of interest.

                                       9
<PAGE>


   Furthermore, PAM's ultimate parent corporation, Pacific Mutual Holding
Company ("PMHC"), is having discussions with Allianz AG regarding a possible
acquisition of PMHC by Allianz AG.

   PHLLC's parent corporation is Pacific Life. Pacific Life's indirect
investment, through its subsidiaries, in PIMCO Advisors represents an important
part of its overall business. As one of the two general partners of our general
partner, PHLLC is involved in the management of PIMCO Advisors, and the
continued management involvement in PIMCO Advisors forms a part of Pacific
Life's ongoing business plan. This affiliation has enhanced Pacific Life's
identity in certain strategic financial services markets. The relationship
between the entities has proven and continues to prove useful in branding,
marketing and selling a number of Pacific Life products and services.
Additionally, Pacific Life utilizes the investment services of Pacific
Investment Management Company and other investment services of PIMCO Advisors.
In this respect, PAM's ownership interest in PIMCO Advisors differs from that
of the investment interest represented by the limited partner units. Although
Pacific Life concluded that the retention by PAM of a management interest in
the general partner of PIMCO Advisors was consistent with Pacific Life's
business plan, Pacific Life believes, based on the information described
elsewhere in this proxy statement, that the consideration offered to the other
partners by Allianz of America is fair to, and in the best interest of, the
Partnership's unitholders.

   The Partnership's partnership agreement provides that the general partner
may resolve all conflicts of interest in good faith and may rely on a fairness
opinion and other expert opinions in doing so. Having received the fairness
opinion described above and taking into account the other matters described in
the proxy statement, in approving the proposed transactions the general partner
did not retain an independent and disinterested third party to represent the
unaffiliated unitholders.

   See "Special Factors--Financial Interests of Certain Persons in the
Transaction" for a more detailed discussion of these different interests,
including without limitation the discussion under "Special Factors--Financial
Interests of Certain Persons in the Transactions--PHLLC and PAM" regarding
Pacific Life's reasons for causing PAM to retain an interest in PIMCO Advisors
rather than selling that interest in the proposed transactions.

Certain Effects of the Merger

   If the merger is completed, all of the Partnership's equity interests will
be indirectly owned by Allianz of America. You will no longer have any interest
in, and will not be a unitholder of, the Partnership, and therefore will not
participate in our future earnings and growth. Instead, your units will be
converted into the right to receive the cash consideration described above for
each Partnership unit you hold. In addition, our Partnership units will no
longer be traded on the New York Stock Exchange, price quotations for our
Partnership units will no longer be available and the registration of our
Partnership units under the Securities Exchange Act of 1934 will be terminated.

Conditions to the Merger

   The completion of the transactions contemplated by the merger agreement (the
"Closing"), including the merger of an indirect subsidiary of Allianz of
America into the Partnership, depends on the satisfaction of a number of
customary conditions, including the accuracy of representations and warranties,
compliance with pre-closing covenants, absence of injunctions or similar legal

                                       10
<PAGE>

impediments which prevent the Closing, receipt of material third party
consents, compliance with certain regulatory requirements and receipt of
necessary government and regulatory approvals and consents. Particularly
noteworthy conditions include:

  .  the merger will not be effected unless our unitholders approve the
     merger agreement, the merger and the other transactions contemplated by
     the merger agreement;

  .  Allianz of America need not complete the merger if the revenue base of
     PIMCO Advisors declines prior to the Closing, for reasons other than
     market movements, to less than 75% of its September 30, 1999 level; and

  .  Allianz of America need not complete the merger unless William H. Gross,
     William S. Thompson and at least 60% of the other managing directors of
     Pacific Investment Management Company remain employed at the Closing.

   In addition, certain other events must occur, including the amendment or
adoption of certain employee benefit plans, the execution of certain employment
contracts with key executives, the restructuring of Pacific Investment
Management Company into a limited liability company and the execution and
delivery of closing documentation.

Termination of the Merger Agreement

   The merger agreement may be terminated by consent of the parties and for
certain failures of representations, warranties or covenants, as well as:

  .  if the transactions contemplated by the merger agreement have not been
     consummated by September 30, 2000;

  .  if our unitholders fail to approve the merger agreement, the merger and
     the other transactions contemplated by the merger agreement;

  .  if our general partner withdraws or adversely modifies its approval or
     recommendation of the merger agreement;

  .  if we enter an agreement involving an acquisition transaction which our
     general partner determines in good faith to be superior to the terms of
     the merger agreement; or

  .  by Allianz of America if PIMCO Advisors' revenue base has declined, at
     the end of two consecutive calendar months, for reasons other than
     market movements, to less than 75% of the September 30, 1999 level.

Termination Fee

   PIMCO Advisors will be required to pay Allianz of America a termination fee
of $180 million ($120 million if the unitholder litigation settlement is
approved) if either:

  .  the merger agreement is terminated by our general partner in connection
     with entering into an agreement involving a superior acquisition
     proposal; or

  .  the merger agreement is terminated by Allianz of America following the
     failure of our general partner to recommend the merger to the
     Partnership unitholders, and, within 12 months after such termination,
     the Partnership, PIMCO Advisors, Partners LLC, PAM, Partners GP or PHLLC
     subsequently enters into another binding agreement for a transaction
     implementing an acquisition proposal.

                                       11
<PAGE>


Financing for the Merger

   The merger is not conditioned upon Allianz of America obtaining financing.
The obligations of Allianz of America and its affiliates under the merger
agreement have been guaranteed by Allianz AG.

Regulatory Approvals

   To complete the merger and the other transactions contemplated by the merger
agreement, we must make filings and receive authorizations from various federal
and state governmental agencies in the United States and various governmental
agencies of foreign jurisdictions. It is possible that some of these
governmental authorities may impose conditions for granting approval. We
anticipate receiving the necessary regulatory approvals, but no one can be sure
that we will obtain all the required regulatory approvals within the time frame
contemplated by the merger agreement.

Material United States Federal Income Tax Consequences

   In general, upon the conversion of your Partnership units into cash pursuant
to the merger, you will recognize gain or loss for United States federal income
tax purposes equal to the difference between the amount of cash you receive,
plus your share of the Partnership's liabilities, if any, and your adjusted tax
basis in your Partnership units. The gain or loss will generally be capital
gain or loss, except that you will recognize ordinary income to the extent any
cash received is attributable to previously allocated amortization deductions
relating to (i) goodwill of the Partnership that is eligible for amortization
pursuant to Section 197 of the Internal Revenue Code of 1986, as amended, and
(ii) other unrealized receivables and inventory of the Partnership within the
meaning of Section 751 of the Internal Revenue Code of 1986, as amended (which
amount attributable to such other unrealized receivables and inventory is not

Recent Developments

   On January 26, 2000, we announced our financial and operating results for
the quarter and fiscal year ended December 31, 1999. The Partnership's net
income for the fourth quarter ended December 31, 1999, was $18.6 million, or
$0.35 per unit (after $0.04 per unit of non-recurring items) and its net income
for the year ended December 31, 1999, was $74.3 million or $1.43 per unit
(after $0.18 per unit of non-recurring items). Net income for the Partnership
during the fourth quarter of 1999 was $21.0 million, or $0.39 per unit before
the effect of non-recurring items, compared with net income of $20.4 million,
or $0.40 per unit, for the fourth quarter of 1998. For fiscal year 1999, net
income increased 9.7% before the effect of non-recurring items and was $83.5
million, or $1.61 per unit, compared to net income of $76.1 million, or $1.52
per unit, for the same period in 1998.

   The net income of PIMCO Advisors for the fourth quarter of 1999 was $57.2
million before the effect of non-recurring items, compared with net income of
$55.2 million in the fourth quarter of 1998. Revenues in the fourth quarter of
1999 increased 7.2% to $244.4 million from $228.0 million in the fourth quarter
of 1998. For fiscal year 1999, net income rose 8.8% before the effect of non-

                                       12

recurring items, and was $226.7 million compared with net income of $208.4
million for the same period in 1998. Annual revenue rose 12.7% to $960.6
million in fiscal year 1999, compared to $852.4 million for the same period in
1998. Including the effect of the non-recurring items, net income at PIMCO
Advisors for fiscal year 1999 was $205.7 million.

   The Partnership's earnings for the fourth quarter of 1999 were affected by
costs related to the proposed transaction between Allianz of America and PIMCO
Advisors of approximately $0.04 per unit, lower than expected performance fees,
and continued net asset outflows from our value managers. The Partnership also
expects to incur additional costs during 2000 related to the proposed
transaction.

                      SELECTED CONSOLIDATED FINANCIAL DATA

   The following tables set forth selected financial data of the Partnership,
retroactively restated to reflect a 1.67 for 1 unit split effective December 1,
1997, for the nine months ended September 30, 1999 and 1998, for the year ended
December 31, 1998, for the eight months ended December 31, 1997 and for the
four years ended April 30, 1997. The tables also set forth selected financial
data for Oppenheimer Capital for the eight months ended December 31, 1997, and
for the four years ended April 30, 1997 and selected consolidated financial
data of PIMCO Advisors for the nine months ended September 30, 1999 and 1998
and for the five years ended December 31, 1998. In the fourth quarter of 1997,
PIMCO Advisors acquired Oppenheimer Capital, and the Partnership's investment
in Oppenheimer Capital was exchanged for an interest in PIMCO Advisors.
Accordingly, the PIMCO Advisors data include the performance of Oppenheimer
Capital from November 4, 1997, and the Partnership data consist of the
performance of PIMCO Advisors from December 1, 1997. PIMCO Advisors and its
subsidiaries were formed on November 15, 1994, when PAM merged certain of its
investment management businesses and substantially all of its assets (the "PAM
Group") into Thomson Advisory Group L.P. ("TAG LP") (the "Consolidation").
Under generally accepted accounting principles, the Consolidation was accounted
for as an acquisition of TAG LP by the PAM Group. Therefore, the historical
financial statements of PIMCO Advisors include the operations of the PAM Group,
in its corporate form, prior to the Consolidation and the combined results of
PIMCO Advisors, in its partnership form, for the period since the
Consolidation. This information should be read in conjunction with the
financial statements of the Partnership, the consolidated financial statements
of PIMCO Advisors and the consolidated financial statements of Oppenheimer
Capital, and the related notes thereto, included in our report on Form 10-K for
the fiscal year ended December 31, 1998 and our Quarterly Reports on Form 10-Q
for each of the three fiscal quarters ended March 31, June 30 and September 30,
1999, and "Management's Discussion and Analysis of Financial Condition and
Results of Operations of PIMCO Advisors Holdings L.P." found in the same Form
10-K and Forms 10-Q.

                         SPECIAL MEETING OF UNITHOLDERS

Date, Time and Place

   We are furnishing this proxy statement to you in connection with the
solicitation of proxies on the form enclosed with this proxy statement by our
general partner for use at a special meeting of our unitholders to be held on
April 28, 2000, at 9:00 a.m. local time, and at any and all adjournments
thereof, for the purposes described below under "Purpose." The meeting will be
held at the Four Seasons Hotel, 690 Newport Center Drive, Newport Beach,
California 92660. This proxy statement and the enclosed form of proxy are being
mailed to you and our other unitholders on or about March 6, 2000.

Purpose

   The purpose of the special meeting is to consider and vote on the proposal
to adopt and approve the merger agreement, the resulting merger in which all of
our Partnership units will be exchanged by way of merger for the right to
receive $38.75 per unit in cash, without interest and subject to potential
downward adjustment to not less than $31.00 per unit ($31.78 per unit if the
unitholder litigation settlement is approved) as described in this proxy
statement under "The Transaction--The Merger: The Acquisition of the
Partnership," and the other transactions contemplated by the merger agreement.
Following the merger, we will no longer be publicly owned. You may also be
asked to transact other business that may properly come before the special
meeting or any adjournment of the special meeting.

Recommendation of Our General Partner

   PIMCO Partners, G.P., our general partner, has approved the merger
agreement, the merger and the other transactions contemplated by the merger
agreement and recommends that you vote "FOR" approval of the merger agreement,
the merger and the other transactions contemplated by the merger agreement. See
"Special Factors--Recommendation; Reasons for the Merger."

Record Date and Units Outstanding

   Our unitholders as of the close of business on the record date of February
29, 2000 are entitled to receive notice of, and to vote at, the special
meeting. Our outstanding Partnership units of limited partnership interest
constitute the only class of securities entitled to vote at the special
meeting, and each such Partnership unit entitles the holder of record to one
vote. At the close of business on February 29, 2000 we had 50,060,365
Partnership units issued and outstanding, held of record by approximately 1,530
registered holders.

Solicitation of Proxies; Expenses

   Our general partner makes this solicitation on our behalf. Allianz of
America and PAM will share equally the costs of the solicitation. Our officers
and employees and our affiliates may also solicit proxies by telephone,
telegraph, telecopy or personal interview, but they will not receive additional
compensation for these solicitation activities. We have retained the services
of D.F. King & Co., Inc., for a fee and related costs, estimated at $100,000,
to assist in the solicitation of proxies. Allianz of America and PAM will
reimburse banks, brokerage firms and other custodians, nominees and fiduciaries
for reasonable and documented expenses incurred by them in sending proxy
materials to you and our other unitholders.

the procedures set forth below is intended to indicate accurately the
unitholder's identity and voting instructions.

   When soliciting a proxy by telephone, the D.F. King & Co., Inc.
representative is required to ask you for your full name, address, social
security or employer identification number, the number of Partnership units you
own and title, if the person giving the proxy is authorized to act for an
entity, such as a corporation. The representative will also confirm that you
have received this proxy statement. The representative will then explain the

confirm your vote. That letter will also ask you to call D.F. King & Co., Inc.
immediately if the confirmation does not reflect your instruction correctly.

Voting of Proxies and Quorum

   If the proxy is properly executed and returned and not revoked, your
Partnership units will be voted as specified in the proxy. Each Partnership
unit that you own on the record date entitles you to one vote. To be voted, the
proxy must be received by our Secretary prior to voting. Our transfer agent
will administer an automated system to tabulate votes cast at the special
meeting.

   If you properly execute and date your proxy, but do not include voting
instructions, your Partnership units will be voted "FOR" the approval of the
merger and the merger agreement. If you properly execute and date your proxy
and mark "ABSTAIN" your units will be counted for the purposes of determining
whether there is a quorum and will have the same effect as a vote against
approval of the merger and the merger agreement. If your Partnership units are
held by your broker, your broker will not vote your units for you unless you
provide instructions to your broker on how to

                                       18
<PAGE>

vote your units. Broker non-votes will be counted as present for purposes of
determining the existence of a quorum and will have the same effect as votes
against approval of the merger and the merger agreement.

   A majority of the outstanding Partnership units entitled to vote,
represented in person or by proxy, will constitute a quorum at the special
meeting. The affirmative vote of the holders of a majority of the Partnership
units outstanding on the record date is required to adopt and approve the
merger agreement, the merger and the other transactions contemplated by the
merger agreement. For these purposes, the vote of Partnership units which are
held by affiliates of the Partnership will be counted. As of February 29, 2000,
affiliates of the Partnership owned 465,440 units representing less than 1% of
the outstanding Partnership units.

Revocability of Proxies

   You may revoke any proxy given pursuant to this solicitation at any time
before its use by:

  .  delivering to us a written notice of revocation;

  .  duly executing a proxy bearing a later date with voting instructions; or

  .  attending the special meeting and voting in person.

Payment of Cash Merger Consideration

   We currently expect the effective time of the merger to occur during the
second quarter of 2000, subject to obtaining requisite approvals and
satisfaction or waiver of the terms and conditions of the merger agreement. See
"The Transaction" and "The Merger Agreement--Conditions to Obligations to
Effect the Transactions." Detailed instructions with respect to the surrender
of your unit certificates, together with a letter of transmittal, will be
forwarded to you by the exchange agent appointed by us and approved by Allianz
of America, promptly following the effective time. You should not submit your
unit certificates to the exchange agent until you receive these materials. The
exchange agent will send payment of the merger consideration to you as promptly
as practicable following determination of the merger consideration and receipt
by the exchange agent of your certificates and other required documents. No
interest will be paid on the merger consideration.

Other Business

   As of the date of this proxy statement, we know of no other business that
will come before the special meeting for action. If any other matter is
properly presented for consideration and action at the special meeting,
however, the proxies will be voted with respect to those matters in accordance
with the best judgment and in the discretion of the proxy holders.

                                THE TRANSACTION

Overview

   The Merger. The merger agreement provides for the acquisition of the
Partnership by Allianz of America through the merger of an indirect subsidiary
of Allianz of America into the Partnership. In the merger, all of the
outstanding limited partner and general partner units in the Partnership will
be converted into the right to receive cash in an amount per unit equal to the
Unit Price, which will be $38.75, without interest and subject to potential
downward adjustment to not less than $31.00 per unit ($31.78 per unit if the
unitholder litigation settlement is approved) as described below. As a result
of the merger, the Partnership will become an indirect wholly-owned subsidiary
of Allianz of America.

   As a result of the merger, all of our equity interests will be indirectly
owned by Allianz of America. You will no longer have any interest in, and will
not be a unitholder of, the Partnership, and therefore will not participate in
our future earnings and growth. Instead, you will have the right to receive the
cash consideration described above for each unit you hold. In addition, the
Partnership units will no longer be traded on the New York Stock Exchange,
price quotations of the Partnership units will no longer be available and the
registration of the Partnership units under the Securities Exchange Act of 1934
will be terminated.

   Subsequent Transactions. Following the merger, subsidiaries of Allianz of
America will, in a series of transactions (the "Subsequent Transactions"),
acquire substantially all of the remaining interests in PIMCO Advisors at the
Unit Price, other than those beneficially owned by PAM, which will retain an
interest in PIMCO Advisors through a new general partner to be formed by PAM
and an affiliate of Allianz of America. As a result of the transactions,
Allianz of America will control PIMCO Advisors, having acquired approximately
70% of the outstanding partnership interests of PIMCO Advisors, and PAM will
retain an interest in PIMCO Advisors on the terms described in this section
under "The Subsequent Transactions--New Advisors Class E Units."

The Merger: The Acquisition of the Partnership

   Allianz of America will acquire the Partnership by way of the merger of
Merger Sub into the Partnership, with the Partnership as the surviving entity
in the merger. As a result of the merger, each of the Partnership units will be
converted into the right to receive the Unit Price, an amount in cash equal to
$38.75, without interest and subject to potential downward adjustment to not
less than $31.00 per unit ($31.78 per unit if the unitholder litigation
settlement is approved) as described below. In addition, each of the units of
general partner interest in the Partnership held by Partners GP will be
converted into the right to receive the Unit Price. As of the date of this
proxy statement, there were 50,060,365 Partnership units outstanding, held of
record by approximately 1,530 registered holders and 5,099 units of general
partner interest in the Partnership outstanding, held by our general partner,
Partners GP.

   As a result of the merger, each limited partnership interest in Merger Sub
will be converted into a limited partnership interest in the Partnership and
the general partner interest in Merger Sub will be converted into a general
partner interest in the Partnership. Accordingly, Allianz of America,
indirectly through subsidiaries, will own all of the partnership interests in
the Partnership after the merger.

   The merger will occur once all conditions in the merger agreement have been
met, including the approval and adoption of the merger agreement, the merger
and the other transactions contemplated by the merger agreement by holders of a
majority of the Partnership units, which is the subject of this proxy
statement. See "The Merger Agreement--Conditions to Obligations to Effect the
Transaction" for a description of the conditions. A certificate of merger will
be filed with the Secretary of State of the State of Delaware specifying the
effective time and date of the merger.

   Adjustment to Unit Price. The Unit Price will be adjusted downward if PIMCO
Advisors' revenue base, expressed as a revenue run-rate, as of the calendar
month-end immediately prior to the

                                       22
<PAGE>

Closing is less than 85% of the revenue run-rate on September 30, 1999. In such
event, the Unit Price will be reduced by 2% for each 1% that the revenue run-
rate falls below 85%, subject to a maximum reduction of 20%. If the settlement
of the unitholder litigation described in this proxy statement is approved by
the court, then the adjustment to the unit price for your units will be reduced
to 1.8% for each 1% decline below the 85% threshold, with a maximum reduction
of 18%. In no event will you receive less than $31.00 per unit ($31.78 if the
settlement is approved) if the merger is approved and consummated. See
"Litigation Challenging the Merger." As a result, the Unit Price can range
between $38.75 and $31.00 per unit or, if the settlement is approved, $31.78.
For example, if the settlement is approved:

            75% or less                      31.78                                   18%
</TABLE>

   The "revenue run-rate" of PIMCO Advisors is calculated based on the
aggregate annualized investment advisory and subadvisory fees for all accounts
managed by PIMCO Advisors and its subsidiaries, and is calculated to exclude
the impact of market movements as described below. Revenue run-rate is
determined by multiplying the "adjusted assets under management" for each such
account by the applicable annual fees for such account at such date (excluding
performance-based fees). Adjusted assets under management for an account means
the amount of assets under management by PIMCO Advisors and its subsidiaries at
September 30, 1999, as adjusted for net cash flows (additions, withdrawals and
reinvestments), new accounts and terminated accounts. For these purposes,
assets are treated as withdrawn if notice has been received communicating an
intention to withdraw the assets (unless the notice has been revoked) or in the
case of registered investment company clients, if the shareholders of that
entity do not approve the assignment of the related advisory agreement which
will occur in connection with the transactions with Allianz of America.

   The calculation of revenue run-rate excludes the effects of market
movements. In light of the historical growth of our largest subsidiary, Pacific
Investment Management Company, and the historical stability of its fixed income
customer base, it would require a significant and unanticipated change to our
previous client redemption history to cause a downward adjustment in the Unit
Price. There will be no downward adjustment in the Unit Price unless PIMCO
Advisors experiences net outflows of assets far in excess of any it has
experienced in the past. Increasing the length of time prior to the Closing
could increase the risk of loss of revenue run-rate and, therefore, the risk of
a downward adjustment to the Unit Price.

   At September 30, 1999, the date of the baseline revenue run-rate
determination, the revenue run-rate was $780.8 million. In order for there to
be a downward adjustment to Unit Price, revenue run-rate would have to fall
below $663.7 million. As of January 31, 2000, the revenue run-rate was $783.5
million, representing 100.34% of its September 30, 1999 level.

The Subsequent Transactions

   Immediately following the merger, subsidiaries of Allianz of America will,
in a series of transactions, acquire substantially all of the remaining
interests in PIMCO Advisors, other than those beneficially owned by PAM, which
will retain an interest in PIMCO Advisors. As a result of the transactions,
Allianz of America will control PIMCO Advisors, having acquired approximately
70% of the outstanding partnership interests of PIMCO Advisors. These
transactions are summarized below.

                                       23
<PAGE>

  Acquisition of Partners GP, PHLLC and Assets of Partners LLC

   Immediately following the merger, Allianz GP Sub will acquire Partners GP
through an acquisition of the managing general partner interest in Partners GP
from Partners LLC and of the member interests of PHLLC, the other general
partner of Partners GP, owned by PAM in the transactions described below.

   Allianz GP Sub will acquire from Partners LLC its 142,480 class A units of
limited partnership interest in PIMCO Advisors (the "Advisors Class A Units")
for cash in an amount per unit equal to the Unit Price, and will acquire
Partners LLC's general partner interest in Partners GP for nominal
consideration of $100 (a total consideration of $5,521,200 at a Unit Price of
$38.75).

   Allianz GP Sub will then acquire PHLLC, the other general partner of
Partners GP. Prior to this acquisition, PHLLC will have distributed to PAM the
22,008,213 Advisors Class A Units beneficially owned by PAM through Partners
GP. The remaining 17,402,107 Advisors Class A Units which will then be owned by
PHLLC, directly and through its interest in Partners GP, are subject to the
terms of certain Employment Termination and Non-Competition Agreements entered
into in 1994 (the "1994 Employment Termination Agreements") under which PHLLC
is the obligor. These agreements provide for noncompete payments to be made to
certain current and former managing directors of Pacific Investment Management
Company equal to the distributions on, or sale proceeds of, the 17,402,107
Advisors Class A Units beneficially owned by PHLLC. Accordingly, while PHLLC
will directly and indirectly own 17,402,107 Advisors Class A Units, it will
have offsetting obligations under the 1994 Employment Termination Agreements to
pay all cash received with respect to those units. Allianz GP Sub will buy
PHLLC for nominal consideration of $100 and will assume the obligations under
the 1994 Employment Termination Agreements described below.

   Following these acquisitions, Allianz of America will control PIMCO
Advisors, owning Partners GP and the Partnership, the two general partners of
PIMCO Advisors.

<PAGE>

   Satisfaction of 1994 Employment Termination Agreements

   As noted above, the 1994 Employment Termination Agreements require PHLLC to
pay to the current and former managing directors of Pacific Investment
Management Company who are parties to those contracts noncompete payments equal
to distributions on, or sales proceeds of, an aggregate of 17,402,107 Advisors
Class A Units. In connection with the merger, the eight managing directors who
are parties to such contracts and who are still acting as managing directors of
Pacific Investment Management Company and one former managing director of
Pacific Investment Management Company have agreed to amend their 1994
Employment Termination Agreements. Each person who has agreed to an amendment
will receive at Closing a payment equal to the Unit Price multiplied by the
number of units which relates to his 1994 Employment Termination Agreement (the
"ETA Payment"), in satisfaction of the noncompete payments payable under that
agreement. The amendments will provide that the noncompete arrangements in the
1994 Employment Termination Agreements will, with some modification remain
binding on the current and former managing directors. Each amendment will
provide:

  .  a covenant not to compete for five years from the Closing (or, for the
     former managing director, for the remainder of the term of his
     covenant);

  .  an agreement to repay the ETA Payment if the noncompete covenant is
     violated during the five-year period; and

  .  the cessation of any further noncompete payments under the 1994
     Employment Termination Agreement.

   Except as provided below, payments will be made in cash and in stock of
Allianz AG. Two of the eight current managing directors of Pacific Investment
Management Company, who are not full-time employees of Pacific Investment
Management Company but who will continue as consultants, and the one former
managing director will receive their ETA Payments solely in cash. The aggregate
payment at the Closing to the current and former managing directors whose 1994
Employment Termination Agreements will be amended will have a value of $649.3
million, based on 16,231,637 Advisors Class A Units, a Unit Price of $38.75 and
an assumed value of $273.99 per share of stock of Allianz AG, the average
trading price for Allianz AG stock for the 30 days prior to public announcement
of discussions between Allianz AG and PIMCO Advisors. Of such aggregate
amounts, at the Closing, Mr. Thompson, the Chief Executive Officer of Pacific
Investment Management Company, and Mr. Gross, the Chief Investment Officer of
Pacific Investment Management Company, will receive ETA Payments in cash and
Allianz AG stock with an aggregate value of $42.7 million and $251.3 million,
respectively (assuming a Unit Price of $38.75 and a value of $273.99 per share
of Allianz AG stock as described above). Because a portion of the payments will
be made in stock of Allianz AG, the value of these payments will fluctuate
based on the price per share of that stock. As March 2, 2000, the trading price
of the Allianz AG stock was $346.94 per share, increasing the aggregate value
of the ETA Payments to $675.9 million, of which Messrs. Thompson and Gross will
receive $45.0 million and $264.7 million, respectively.

   The 1994 Employment Termination Agreement of one former managing director of
Pacific Investment Management Company will not be amended, and he will not
receive any payments at Closing with respect to his agreement. Following the
Closing, PHLLC, which will then be an indirect subsidiary of Allianz of
America, will continue to make noncompete payments under that agreement to that
former managing director. Following the acquisition of Partners GP described
above, Allianz of America will cause Partners GP to retain a number of Advisors
Class A Units equal to those with respect to which payments are due under the
remaining 1994 Employment Termination Agreement. In the Advisors Merger
described below, those units will be converted into new Class B Units of

                                       25
<PAGE>

limited partnership in PIMCO Advisors (the "Advisors Class B Units"). The new
Advisors Class B Units will have a liquidation preference equal to the Unit
Price and include the right to receive a distribution equal to 7.5% of the Unit
Price per annum, payable quarterly. Unless the Advisors Class B Units are
redeemed on the terms described below, through the period ending in November
2036, PHLLC, which will then be a subsidiary of Allianz of America, will make
noncompete payments based on the distributions from those new Advisors Class B
Units. Commencing five years after the Closing, the former managing director
may require that any or all Advisors Class B Units on which his employment
termination payments are based be redeemed at the Unit Price (plus accrued and
unpaid distributions) by PIMCO Advisors, and commencing ten years after the
Closing, or earlier upon certain circumstances, PIMCO Advisors may redeem the
Advisors Class B Units at the Unit Price (plus accrued and unpaid
distributions) in its discretion. Upon any such redemption, the redemption
price will be paid to the former managing director who is a party to the
remaining 1994 Employment Termination Agreement, in accordance with that
agreement. In addition, the former managing director may elect to receive that
cash immediately upon the execution of an amendment similar to those described
above in which the managing directors agree to extend the duration of the non-
competition provisions.

   Contributions to PacPartners

   Following the acquisitions of PHLLC and Partners GP, Allianz GP Sub and PAM
will make or cause to be made contributions to a new limited liability company,
PacPartners, which will serve as the general partner of PIMCO Advisors
following the completion of the transactions under the merger agreement.
Allianz GP Sub will cause PHLLC to contribute 16,231,637 Advisors Class A Units
and the Advisors GP Unit (all of the units acquired from Partners LLC, PHLLC
and Partners GP other than those to be held at Partners GP following the
Closing) in exchange for 100% of the Class A Interests of PacPartners.

   PAM will then contribute to PacPartners its 22,838,416 Advisors Class A
Units in exchange for 100% of the Class E Interests of PacPartners. These
Advisors Class A Units comprise all of the Advisors Class A Units PAM
beneficially owns (directly and through subsidiaries) other than those owned by
its corporate subsidiary PacFin. If $130 million in nonrecourse indebtedness
(the "Contributed Note") is not repaid by Partners GP then, subject to the
consent of lenders to Partners GP, PAM will contribute to PacPartners the
Advisors Class A Units which are subject to the Contributed Note. The number of
Advisors Class A Units to be contributed may be reduced by 15,741 if consents
of certain partially owned limited partnership subsidiaries of PAM are not
obtained. Under those circumstances, the units not contributed will be
converted to cash at the Unit Price in the Advisors Merger along with all other
units in those partially owned limited partnership subsidiaries.

   As described below, in the Advisors Merger, PacPartners will receive a
number of new Advisors Class E Units based on the number of Advisors Class A
Units contributed by PAM to PacPartners. The Class E Interests of PacPartners
owned by PAM will entitle PAM to receive distributions equal to the
distributions received by PacPartners on the Advisors Class E Units, less any
required principal or interest payments on the Contributed Note, if it remains
outstanding, and certain expenses of PacPartners.

   Contributions to Advisors Merger Sub

   Immediately after the formation of PacPartners, in preparation for the
Advisors Merger, PacPartners will contribute its Advisors Class A Units to
Advisors Merger Sub, a wholly-owned

                                       26
<PAGE>

limited liability company subsidiary of Allianz GP Sub, which, at that time,
will hold cash received from Allianz of America in an amount sufficient to
satisfy all of its obligations in the Advisors Merger.

   PacPartners will contribute its Advisors Class A Units to Advisors Merger
Sub in exchange for Class A Units and Class E Units of limited partner interest
in Advisors Merger Sub, with these Class A and Class E Units being issued in
proportion to the Class A and Class E Interests in PacPartners owned by PHLLC
and PAM, respectively. PacPartners will also contribute its PIMCO Advisors
general partner unit to Advisors Merger Sub for an Advisors Merger Sub GP Unit.

   Allianz of America will cause the Partnership to contribute its Advisors GP
Units (49,564,071 as of October 31, 1999) to Advisors Merger Sub in exchange
for Advisors Merger Sub Class A Units.

   PAM will cause PacFin to contribute all of its 14,380,217 Advisors Class A
Units to Advisors Merger Sub in exchange for 1,438 Class E units of limited
liability company interest in Advisors Merger Sub (representing one Class E
unit for each 10,000 Advisors Class A Units contributed).

   Advisors Merger

   Following the above described transactions, Advisors Merger Sub will merge
into PIMCO Advisors, with PIMCO Advisors being the surviving entity in the
merger (the "Advisors Merger").

   In the Advisors Merger:

  .  All Advisors Class A Units, other than those owned by Advisors Merger
     Sub and Partners GP (which will then be an indirect subsidiary of
     Allianz of America), will be converted into the right to receive cash at
     the Unit Price.

                                       27
<PAGE>

  .  The Advisors Class A Units and the one Advisors GP Unit held by Advisors
     Merger Sub will be cancelled. The 1,170,470 Advisors Class A Units held
     by Partners GP will be converted into the new Class B Units of PIMCO
     Advisors described above.

  .  Advisors Merger Sub Class A Units held by PacPartners and the
     Partnership will be converted into new Class A Units of PIMCO Advisors.

  .  The Class E Units in Advisors Merger Sub held by PacFin and PacPartners
     will be converted into new Class E Units of limited partnership in PIMCO
     Advisors ("Advisors Class E Units").

  .  PacPartners will be admitted as the general partner of PIMCO Advisors.

  .  All Class C Units of PIMCO Advisors (owned by a subsidiary of PIMCO
     Advisors) will remain outstanding. All Class D Units of PIMCO Advisors
     (owned by the managing directors of the PIMCO Equity Advisors division)
     will remain outstanding.

   New Advisors Class E Units

   As a result of the Advisors Merger, PAM, through its subsidiary PacFin and
its interest in PacPartners, will maintain its investment in PIMCO Advisors
through beneficial ownership of Advisors Class E Units. The Advisors Class E
Units will be entitled to distributions which, on an annual basis, in the
aggregate will equal:

  .  $1.05 per Advisors Class A Unit previously beneficially owned by PAM, a
     fixed return representing the historical returns from PIMCO Advisors'
     retail and equity asset management business; plus

  .  20% of the adjusted operating profit available for distribution
     ("Adjusted OPAD") of Pacific Investment Management Company.

                                       28
<PAGE>

   For these purposes, the Adjusted OPAD of Pacific Investment Management
Company will be calculated in accordance with the provisions of the Pacific
Investment Management Company Profit Sharing Plan in effect at the Closing,
before payment of profit sharing bonuses under that plan and without taking
into account:

  .  income attributable to performance fees which are subject to forfeiture;

  .  deductions for annual compensation paid to employees above $450,000,
     adjusted for inflation after the year 2000;

  .  deductions attributable to certain option and deferred compensation
     benefits; and

  .  severance and executive retention payments paid pursuant to the merger
     agreement.

   The calculation will also exclude the effect of:

  .  certain costs and revenues associated with the provision of management
     or subadvisory services with respect to certain assets; and

  .  the subsidy, if any, by Allianz of America to the Pacific Investment
     Management Company bonus pool in 2000 through 2002.

   The distributions with respect to the Advisors Class E Units were designed
to limit PAM's return to a variable return based on the operating profit of
PIMCO Advisors' fixed income asset management business, plus a fixed return
representing PAM's historical returns from PIMCO Advisors' retail and equity
asset management business. Allianz AG negotiated a fixed return for the retail
and equity business in order to provide it with the flexibility it requires to
restructure the PIMCO Advisors' retail and equity asset management business and
combine it with existing Allianz AG equity asset management businesses.
Pursuant to the agreements between Allianz AG and the Pacific Investment
Management Company managing directors, Allianz AG is committed to continue to
permit the Pacific Investment Management Company fixed income business to
operate autonomously. More details on the arrangements with Pacific Investment
Management Company are found in "Special Factors--Financial Interests of
Certain Persons in the Transaction--Partners GP--Partners LLC."

   In connection with the Closing, Allianz of America and PAM will enter into a
put and call agreement providing for the possible disposition of the Advisors
Class E Units. See "Special Factors--Financial Interests of Certain Persons in
the Transaction--Partners GP--PHLLC and PAM."

Treatment of Employee Benefit Awards

   1998 Unit Incentive Plan. In connection with the Closing, all outstanding
unit options under the 1998 Unit Incentive Plan of PIMCO Advisors Holdings L.P.
and PIMCO Advisors L.P. (the "1998 Unit Incentive Plan"), whether exercisable
or not, will be cancelled and terminated and will thereafter represent the
right to receive a cash payment equal to the excess of the Unit Price over the
exercise price per unit of such unit option, multiplied by the number of units
subject to such unit option, together with interest on such amount at 8% per
annum from the effective time of the merger through the date such payment is
made. It is anticipated that such payment will be made approximately 100 days
following the Closing. Based on the number of outstanding unit options as of
January 31, 2000, and assuming a Unit Price of $38.75, it is expected that an
aggregate of $150 million, together with interest on such amount at 8% per
annum from the effective time of the merger through the date such payment is
made as described in the preceding sentence, will be paid in settlement of
these unit options following the Closing. Deferred unit awards under the 1998
Unit Incentive Plan will, after the

                                       29
<PAGE>

Closing, reflect the right to receive, on the vesting date of such deferred
unit award, cash equal to the Unit Price, multiplied by the number of units
underlying such award, plus interest at 8% per annum from the Closing through
the vesting date of such awards. Deferred unit awards will continue to vest
according to their existing vesting schedules. For additional discussion of the
1998 Unit Incentive Plan, see "Special Factors--Financial Interests of Certain
Persons in the Transaction--The Partnership--Unit Option Awards" and "--
Partners GP--Partners LLC--Unit Options and Deferred Compensation Plan."

   Executive Deferred Compensation Plan. The Executive Deferred Compensation
Plan of PIMCO Advisors Holdings L.P. and PIMCO Advisors L.P. (the "Deferred
Compensation Plan") provides for mandatory and elective deferrals of
compensation, as well as deferral of awards of deferred restricted units.
Amounts deferred are credited to a trust and invested in Advisors Class A
Units. In connection with the Closing, the Advisors Class A Units held by the
trustee, other than those related to deferred restricted unit awards, will be
exchanged for cash in an amount per unit equal to the Unit Price. Under the
terms of the plan, any unvested account balances reflecting discount investment
or reinvestment of deferred compensation will vest at the Closing. Each
Advisors Class A Unit representing an unvested deferred restricted unit held in
the trust generally will not vest, and will be exchanged by the plan trustee
for a note from Allianz of America with a principal balance equal to the Unit
Price multiplied by the number of unvested units. The note will bear interest
at 8% per annum and be payable as and when the deferred restricted units would
have vested under their existing vesting schedules. Following the Closing, it
is expected that plan participants' account balances will be measured by, and
the assets held by the plan's trustee will be invested in, such investments as
may be individually directed by each participant. For additional discussion of
the Deferred Compensation Plan, see "Special Factors--Financial Interests of
Certain Persons in the Transaction--The Partnership--Deferred Compensation
Plan."

Financial Interests of Certain Persons in the Transaction

   The merger agreement also sets forth additional benefits that will be
received by the executive officers and management board members of the
Partnership as well as the members of PHLLC and Partners LLC, who own Partners
GP, our general partner. These interests include new employment and consulting
agreements and retention payments intended to maintain those employment and
consulting relationships. These persons will receive aggregate cash payments of
up to $470.7 million and 182,488 shares of Allianz AG stock, payable in most
instances over a five year period contingent on continued employment in
employment-related compensation, as well as aggregate closing payments of
$614.5 million in cash and 364,977 shares of Allianz AG stock in settlement of
pre-existing unit based entitlements in connection with the transactions. The
shares of Allianz AG stock described above would have an assumed aggregate
value of $50.0 million and $100.0 million, respectively, at $273.99 per share
which was the average closing price for such stock for the 30 days prior to the
public announcement of discussions between Allianz AG and PIMCO Advisors. As of
March 2, 2000, the closing price of the Allianz AG stock was $346.94 per share,
increasing the value of such stock to $63.3 million and $126.6 million,
respectively. Each of these interests is described more completely in "Special
Factors--Financial Interests of Certain Persons in the Transaction."

Payment of Expenses

   It is currently anticipated that the expenses of PIMCO Advisors related to
the merger and the Subsequent Transactions will be approximately $30 million to
$35 million, of which $20 million to $25 million or $0.18 to $0.22 per
Partnership unit, will be borne by PIMCO Advisors after taking

                                       30
<PAGE>

into account the obligations under the merger agreement of PAM and Allianz of
America to pay a portion of those expenses. These transaction expenses will
reduce PIMCO Advisors' operating profit available for distribution and,
therefore, the distributions payable on your Partnership units prior to the
Closing, or if the Closing does not occur, during calendar year 2000. See "The
Merger Agreement--Certain Covenants--Expenses."

Estimated fees and expenses (rounded to the nearest thousand) to be incurred by
the Partnership or PIMCO Advisors in connection with the merger and the
Subsequent Transactions are as follows:

</TABLE>
- --------
(1) Portions of these expenses will not be borne by the Partnership or PIMCO
    Advisors but will be paid by Allianz of America and PAM. In particular,
    pursuant to the terms of the merger agreement, PAM and Allianz of America
    have agreed to each bear 50% of the expenses incurred by the Partnership in
    connection with the solicitation of the Partnership's unitholders, and
    Allianz of America has agreed to bear 50% of the expenses incurred by the
    Partnership in connection with the solicitation of shareholders of the
    registered investment companies.

No Appraisal Rights

   Holders of the Partnership units are not entitled to dissenting unitholders'
appraisal rights or other similar rights under Delaware law or the
Partnership's partnership agreement.

Benefits and Detriments to Holders of Partnership Units

   Our general partner believes that the merger will result in the following
benefits to you as a holder of Partnership units: realizing the value of your
investment in the Partnership in cash at a price which is higher than the
historical trading price of the Partnership units and which represents a
substantial premium to the market price for the Partnership units prior to the
reporting by the press of discussions between the Partnership and Allianz AG
and eliminating the risk of a decline in the value of your investment in the
Partnership.

   The primary detriment to you, as a holder of Partnership units, is that you
will cease to have any ownership interest in the Partnership and will cease to
participate in future earnings or growth, if any, of the Partnership or benefit
from increases, if any, in the value of the Partnership. In addition, most
holders of Partnership units are expected to recognize a taxable gain upon the
completion of the merger.

Plans for the Partnership After the Merger

   Immediately following the completion of the merger and the other
transactions contemplated by the merger agreement, the Partnership will be an
intermediate holding company, 100% owned by Allianz GP Sub and having Advisors
Class A Units as its only assets. The Partnership will have no

                                       31
<PAGE>

subsidiaries. Although Allianz of America currently has no definitive plans or
proposals for an extraordinary transaction involving the Partnership or a
restructuring of the Partnership, Allianz of America may, as part of
rationalizing the holding company structure through which it controls PIMCO
Advisors or for other reasons, cause the transfer of such Advisors Class A
Units to another affiliate of Allianz of America, wind up and dissolve the
Partnership or take similar steps. In any event, it is not expected that the
current officers of the Partnership will continue to serve, because the
Partnership will not require any management personnel separate from the
general partner of the Partnership. Allianz of America will control the
Partnership and PIMCO Advisors after the Closing, and PAM will not have the
authority to direct actions taken by either the Partnership or PIMCO Advisors.
However, PacPartners and PIMCO Advisors will not be able to take specified
actions without PAM's prior approval. See also the information under
"Summary--Certain Effects of the Merger" and "Special Factors--Financial
Interests of Certain Persons in the Transaction--Partners GP--PHLLC and PAM--
Continuing Investment in PIMCO Advisors."

Conduct of Business of the Partnership if the Merger is not Consummated

   If the merger and the Subsequent Transactions are not consummated, the
business and operations of the Partnership are expected to be conducted
substantially as currently conducted.

Accounting Treatment

   The merger will be accounted as a purchase under U.S. generally accepted
accounting principles.

                                Recommendation;
                             Reasons For The Merger

Recommendation

   Our general partner and its general partners, Partners LLC and PHLLC, as
well as PHLLC's parent entities PAM and Pacific Life, believe that the merger
and the terms of the merger agreement are fair and in the best interests of the
Partnership and our unaffiliated unitholders. Accordingly, Partners LLC and
PHLLC caused our general partner to approve the merger agreement, the merger
and the other transactions contemplated by the merger agreement and our general
partner, Partners LLC, PHLLC, PAM and Pacific Life recommend approval of the
merger agreement, the merger and other transactions contemplated by the merger
agreement by the limited partnership unitholders of the Partnership as set
forth below.

Reasons for the Merger

   We have pursued a growth strategy to increase the amount and diversification
of assets under management by PIMCO Advisors and its subsidiaries. We have
pursued that strategy both through internal investment and through targeting
existing investment managers and selectively acquiring or hiring those that
have demonstrated strong investment performance or who are expected to provide
complementary products and investment philosophies to PIMCO Advisors' existing
investment management groups.

   We began exploring opportunities for expansion into the European market in
particular because with the prospect of the adoption of the Euro, we believed
that the time was appropriate to take advantage of significant new
opportunities in the European fixed income market. We believe the adoption of
the Euro presents the opportunity to build a fixed income market in Europe with
significantly more breadth and depth than has historically been the case.
Historically, the European fixed income market has been based on country
specific economic analysis and currency trends. The European fixed income
market which is currently developing presents the opportunity for Pacific
Investment Management Company to apply its expertise and proprietary methods to
this new and growing market.

   Through this process, we have come to believe that the failure to capitalize
on this new market opportunity could have adverse impacts on our business:

  .  Recent mergers and combinations in the financial services industry are
     producing large and powerful global companies able to provide a full
     range of financial services through well developed retail distribution
     channels.

  .  While PIMCO Advisors has a leading position in the domestic fixed income
     market, its presence in the equity market and retail distribution is
     relatively small compared to many of our competitors.

  .  While the US market is still the largest in the world, significant
     growth is taking place outside the US, particularly in Europe.

   Based on the globalization of the securities markets, the increasing
consolidation of financial services companies resulting in large and powerful
global players and the opportunities presented by financial changes in Europe,
we believe that the continued future success of PIMCO Advisors will depend in
part on becoming a global financial services company with significant depth in
overseas markets, particularly in Europe.

                                       33
<PAGE>

   We also came to believe that strategies necessary for future growth entailed
increasing risks:

  .  Expansion outside the U.S. requires incurring substantial costs for
     building the infrastructure and large-scale retail distribution channels
     needed to compete effectively in these markets on a meaningful scale.
     Our partnership structure makes this difficult, as these costs would
     have a significant negative impact on our current distributions, while a
     return on investment would not be expected in the near term. PIMCO
     Advisors has been pursuing offshore growth in recent years with
     expansions into London, Tokyo, Singapore, Sydney and other financial
     centers, which have shown some promise but have also been expensive and
     presented challenges to obtaining the scale and level of distribution
     necessary.

  .  While the PIMCO Equity Advisors division achieved significant investment
     success and business growth during the last year (assets under
     management have grown from $4.5 billion to $9.6 billion from inception
     at January 4, 1999 through December 31, 1999), conditions in the equity
     markets generally have disfavored our much larger value and growth at a
     reasonable price investment styles. Assets managed by Oppenheimer
     Capital, a value manager, Cadence Capital Management, a manager in the
     growth at a reasonable price style, and NFJ Investment Group, another
     value manager, together comprised $64.5 billion of assets under
     management at September 30, 1999, which represented 76.1% of our equity
     assets and 24.9% of our total assets under management at that date.
     Oppenheimer Capital has been experiencing net asset outflows for seven
     consecutive quarters through December 31, 1999.

   These challenges to internal growth led us to believe that long term
success, particularly internationally, made it important to form a strategic
alliance or merge with a suitable global partner from among the larger European
and global financial services companies, where PIMCO Advisors could combine its
expertise with a partner's strength in the European market.

   We have from time to time engaged in discussions with global investment
banks and other investment advisors and financial services companies. In
pursuit of this goal to expand globally and into Europe in particular, these
discussions included exploring the possibility of expanding into foreign
markets through a business combination. In pursuing this strategy, we worked
closely with PIMCO Advisors' financial advisor, Lazard Freres & Co. LLC, to
better understand the European and global investment advisor and financial
services markets and the strategic alternatives for an expansion by PIMCO
Advisors into the European market. Our discussions are summarized in the
following section, "--Background of the Transaction."

   Factors that we considered in evaluating prospects included:

  .  A demonstrated ability to distribute investment products in targeted
     markets;

  .  Complementary investment management and product capabilities providing
     opportunities for operating synergies;

  .  Commitment to the investment management business, including the
     willingness to share access to customers, commit resources and leverage
     corporate relationships;

  .  The cultural "fit" between the companies, including track record with
     other joint ventures, long or short-term orientation and the extent and
     the nature of the control it would expect to exercise;

  .  Whether it desired to be a regional, European or global player; and

  .  Investment management operations outside of Europe.

                                       34
<PAGE>

   While we did not enter into these discussions with the intention of selling
the Partnership, neither did we rule out the possibility that a sale could
produce the best value for our unitholders. These discussions did not result in
any offers, other than from Allianz AG. Among other things, our structure as a
partnership made many otherwise potentially attractive combinations
unattractive because of tax and structural concerns. For example, any
transaction involving the exchange of the stock of a buyer either for your
units or for the assets of the Partnership or PIMCO Advisors generally would
have been a taxable event for you without providing you (or the Partnership or
PIMCO Advisors) with any cash to pay the related tax liabilities. This is
because such an exchange would have been treated as a taxable disposition of
either your units or the assets of the Partnership or PIMCO Advisors, resulting
in the recognition of taxable gain without the receipt of cash attributable to
such gain. In addition to these significant tax issues, a non-cash transaction
with a foreign buyer would be problematic if (as is the case with Allianz AG)
the buyer did not have securities traded in the United States. Also, such a
transaction could result in our unitholders receiving shares which reflected a
very different investment--a large global financial services company (Allianz
AG has significant worldwide insurance operations) of which our investment
advisory business would be only a portion. Finally, it was imperative that a
transaction result in the right business "fit" between parties to produce the
synergies necessary to achieve the highest value for the PIMCO Advisors
business in any combination, whether a sale or purchase.

   As part of this process we considered appropriate valuations for the
Partnership's equity. In consultation with our advisors, we examined the
valuation metrics and methodologies described below under "--Opinion of Our
Financial Advisor," which include peer group analysis, valuations and market
premiums found in other transactions in our industry, and valuations based on
discounted cash flows.

   We believe the Allianz transaction meets these criteria. We believe the sale
of the Partnership to Allianz of America as contemplated by the merger
agreement is in the best interests of our unitholders. In determining to
approve and recommend unitholders' approval of the merger and the merger
agreement, and in reaching its determination that the merger and the merger
agreement are fair to and in the best interests of the Partnership's limited
partnership unitholders, our general partner, in consultation with the
Partnership's executive officers, considered the following:

  1. Our review and analysis of PIMCO Advisors' business, current and future
     financial condition, current earnings and earnings prospects, and the
     competitive business environment facing PIMCO Advisors, noting in
     particular the development of global financial services companies
     through mergers and combinations, the challenges facing our equity and
     retail distribution businesses and the growth of the European market
     which presents significant new, although uncertain, opportunities for
     our investment advisory business;

  2. Historical market prices of the Partnership's limited partnership units
     and the fact that the per unit consideration of $38.75 to be paid in the
     merger represents a premium for the publicly traded limited partnership
     units of approximately 31% over the unit price on July 6, 1999, the last
     trading day before the press reports of discussions between PIMCO
     Advisors and Allianz AG began affecting the Partnership's unit price,
     approximately 27% over the unit price on October 4, 1999, the last
     trading day before the Partnership announced negotiations with Allianz
     AG, approximately 12% over the unit price on October 29, 1999, the last
     trading day prior to the execution of the merger agreement and
     approximately 30% over the 200 day moving average of the closing price
     of the Partnership units prior to July 7, 1999;

                                       35
<PAGE>

  3. Our conclusion, after review and analysis, that long term success in the
     investment management business requires significant global growth and
     presence, particularly in Europe, which we concluded we were unlikely to
     achieve in the near term through internal growth, due in part to
     significant costs that would be required to establish a substantial
     foreign presence.

  4. A review of the following possible alternatives to the merger:

    .  the prospects of continuing operations as they now stand and the
       risks in the operation of our current business, including challenges
       in competing with large global financial service providers in an
       increasingly consolidated industry, challenges to the growth and
       expansion of our equity operations and the risks associated with the
       global expansion considered necessary to our future prospects;

    .  the costs of building a European operation through internal growth
       alone, and chances of success in doing so;

    .  forming a joint venture with or acquiring European or global asset
       management companies;

    .  the value to unitholders of the alternatives and the timing and
       likelihood of actually achieving additional value from these
       alternatives;

    .  structural and tax impediments to certain alternative transactions
       due to our organization as a partnership; and

    .  the possibility that PIMCO Advisors' future performance might result
       in a lower unit price than the merger consideration;

  5. Our conclusion, following the investigation of the foregoing
     alternatives which did not involve a sale of the business, that the
     transaction proposed by Allianz AG produced the best value to our
     unitholders;

  6. The financial presentation of Salomon Smith Barney, including its
     opinion, dated October 29, 1999, as to the fairness from a financial
     point of view of the consideration to be received by the public holders
     of Partnership Units and certain holders of Advisors Class A Units in
     connection with the merger, as described below in "--Opinion of Our
     Financial Advisor";

  7. The opinion of McLagan Partners, Inc., dated October 29, 1999, which
     concluded that the proposed management retention incentive arrangements
     for executives of Pacific Investment Management Company are reasonable
     and suitable to achieve the objective of retaining and motivating these
     employees; and

  8. The likelihood of consummation of the merger and the other transactions
     contemplated by the merger agreement, including an assessment of the
     risks associated with obtaining necessary federal and state regulatory
     approvals and the possibility of the merger and the other transactions
     contemplated by the merger agreement not being consummated even if
     approved by unitholders.

   The opinion of Salomon Smith Barney is dated as of October 29, 1999 and
opines as to the fairness as of that date only. Salomon Smith Barney is not
obligated to update its opinion. Events could occur prior to the date of the
special meeting which could result in a different valuation or conclusion if
the opinion was reissued on that date. In the event that there are material
changes to the

                                       36
<PAGE>

terms of the proposed transactions or other material changes or conditions
affecting the Partnership or its business, our general partner will consider
the advisability of requesting an updated fairness opinion at that time. As of
the date of this proxy statement, the general partner does not believe any such
material changes have occurred.

   In view of the wide variety of factors considered in connection with our
evaluation of the merger agreement, we did not find it practicable to, and did
not, quantify or otherwise attempt to assign relative weights to the foregoing
factors. We viewed our position and recommendation as being based on the
totality of the information presented to and considered by us. However, the
financial measures given particular weight by us included the 31% premium to
the trading price of the Partnership units the day prior to the first press
reports about the proposed transaction as discussed above, and the discounted
cash flow analysis provided by Salomon Smith Barney, which concluded that the
Unit Price was within a range of values from $28.82 to $45.57 per Partnership
unit implied by its analysis. See "--Opinion of Our Financial Advisor." We
believe a discounted cash flow analysis is a good measure of the Partnership's
and PIMCO Advisors' value in light of their partnership structures which
provide for continuous distribution of cash flow through quarterly
distributions.

   Financial measures that we considered but did not believe to be as relevant
to a determination of fairness include (i) valuation based on net book value,
because we believe that the net book value of the Partnership and PIMCO
Advisors, as determined under generally accepted accounting principles, is not
indicative of market value because of the Partnership's significant goodwill
and the continuous distribution of cash flows to the limited partners which
prevents net book value from adequately measuring potential growth of the
business and (ii) analysis of going concern value and of liquidation value,
because the value-added assets of the Partnership and PIMCO Advisors are its
portfolio managers, not traditional hard assets which can be sold.

   While the foregoing discussion of the information and factors we considered
is not intended to be all-inclusive, it does constitute a summary of the
material information we considered in determining to recommend approval of the
merger agreement, the merger and the other transactions contemplated by the
merger agreement.

   We believe the proposed transaction is procedurally fair to the unaffiliated
unitholders. The Partnership's partnership agreement provides that our general
partner has the exclusive right and full power to manage and control the
business of the Partnership and provides that our general partner may approve
or disapprove, without a vote of limited partners, a merger in which the
Partnership is the surviving entity. The Partnership's partnership agreement
provides that our general partner may resolve all conflicts of interest in good
faith and may rely on a fairness opinion and other expert opinions in doing so.
Having received the fairness opinion described above and taking into account
the other matters described in this proxy statement, in approving the proposed
transaction our general partner did not retain an independent and disinterested
third party to act solely on behalf of unaffiliated unitholders or submit the
decision for approval of a board of independent persons. In accordance with the
Partnership's partnership agreement and Delaware law, the transactions were
approved by our general partner, Partners GP, through action of its two owners,
Partners LLC and PHLLC (through board approval of its member, PAM). The
Partners GP partnership agreement requires that both owners approve mergers
involving the Partnership.

   Additionally, our general partner determined to put the matter to a vote of
the limited partners. While the Partnership's partnership agreement does not
require that the proposed merger be put to a vote, in light of the significance
of the transaction to the Partnership and its unitholders, as well as conflicts
of interest of our general partner and its owners inherent in the transaction,
our general partner has decided to seek the approval of the unitholders.
Section 17-211(b) of the Delaware

                                       37

Revised Uniform Limited Partnership Act provides that, unless otherwise
provided in the partnership agreement, a merger or a consolidation shall be
approved by all general partners and by limited partners who own more than 50%
of the then current percentage in the profits of the limited partnership owned
by all limited partners. Because every limited partner will be entitled to
vote, the vote is not limited to unitholders unaffiliated with our general
partner. However, as of February 29, 2000, affiliates of our general partner
held less than 1% of the Partnership's units and, as a result, are not expected
to significantly impact the vote.

                         Background of the Transaction

   As an ongoing part of our growth strategy, we have from time to time engaged
in discussions with global investment banks and other investment advisors and
financial services companies. In furtherance of our desire to expand globally
and into Europe in particular, these discussions included exploring the
possibility of expanding into foreign markets through a business combination.
For more about this strategy and the reasons for the merger, see "--
Recommendation; Reasons for the Merger."

   In pursuing this strategy, PIMCO Advisors worked closely with its financial
advisor, Lazard Freres, to better understand the European and global investment
advisor and financial services markets. In particular, on July 15, 1998, Lazard
Freres made a presentation to Mr. William Thompson, the Chief Executive Officer
and a managing director of Pacific Investment Management Company and the Chief
Executive Officer of Partners LLC, certain other managing directors of Pacific
Investment Management Company and Mr. Kenneth Poovey, Chief Operating Officer
of the Partnership and PIMCO Advisors. The presentation of Lazard Freres
focused on the European investment advisor and financial services markets and
various strategic alternatives for an expansion by PIMCO Advisors into the
European market. In addition, the presentation explored the business objectives
to be sought in an expansion into the European market and discussed the
criteria to be employed for evaluation of potential business partners in the
event that the strategic alternative for expansion into the European market
involved a business combination. The presentation concluded by reviewing
potential candidates for a business combination that would allow PIMCO Advisors
to expand into the European market.

   Commencing in January 1998 and continuing through the summer of 1999,
representatives of PIMCO Advisors engaged in discussions with global financial
services firms which did not result in any offers. Among other things, our
structure as a partnership made many otherwise potentially attractive
combinations unattractive because of tax and structural concerns. For example,
any transaction involving the exchange of the stock of such a firm either for
your units or for the assets of the Partnership or PIMCO Advisors generally
would have been a taxable event for you without providing you (or the
Partnership or PIMCO Advisors) with any cash to pay the related tax
liabilities. This is because such an exchange would have been treated as a
taxable disposition of either your units or the assets of the Partnership or
PIMCO Advisors, resulting in the recognition of taxable gain without the
receipt of cash attributable to such gain. In addition to these significant tax
issues, a non-cash transaction with a foreign buyer would be problematic if (as
is the case with Allianz AG) the buyer did not have securities traded in the
United States. Also, such a transaction could result in our unitholders
receiving shares which reflected a very different investment--a large global
financial services company (Allianz AG has significant worldwide insurance
operations) of which our investment advisory business would be only a portion.
Finally, it was imperative that a transaction result in the right business
"fit" between parties to produce the synergies necessary to obtain the highest
value for the PIMCO Advisors business in any combination, whether a sale or
purchase.

   In the summer of 1998, representatives of PIMCO Advisors contacted Dr.
Joachim Faber, then Chief Financial Officer and Member of the Board of
Management of Allianz Versicherungs--AG, to discuss the possibility of an
acquisition by PIMCO Advisors of Allianz AG's asset management operations. At
that time, Dr. Faber expressed that Allianz AG was not in a position to engage
in such discussions. In September 1998, Dr. Faber contacted Mr. Poovey and
expressed an interest in exploring a possible transaction between Allianz AG
and PIMCO Advisors.

   Between October 1998 and July 1999, various representatives of PIMCO
Advisors and Allianz AG engaged in a series of meetings at which the parties
explored the possibilities for a combination of the two companies. The
meetings, which took place in California, New York and Germany, enabled Allianz
AG and PIMCO Advisors to learn about each other's businesses, asset management
operations, corporate cultures and management styles.

   During these discussions, representatives of Allianz AG indicated their
desire to explore a transaction structure that would enable Allianz AG to
acquire majority ownership and control of PIMCO Advisors. The parties discussed
a transaction which would involve the acquisition in a cash transaction by
Allianz AG of the Partnership's 44% interest in PIMCO Advisors and
substantially all of the other interests in PIMCO Advisors other than those
beneficially owned by PAM, which the parties understood not to be available for
sale. Representatives of PIMCO Advisors told representatives of Allianz AG in
meetings held on March 2 and 3, 1999, that terms of a potentially acceptable
transaction would likely include a unit price in the range of $40, continued
autonomy in the management of PIMCO Advisors' investment management
subsidiaries, Pacific Investment Management Company's assuming global
responsibility for fixed income asset management for the combined companies,
and the establishment of appropriate employee retention and incentive
arrangements in order to preserve the business of PIMCO Advisors.

   On May 21, 1999, PIMCO Advisors retained Lazard Freres to advise it in
connection with strategic discussions with Allianz AG.

   In June 1999, representatives of Putnam, Lovell, De Guardiola & Thornton,
Inc., the financial advisor retained by Allianz AG, discussed with Mr.
Thompson, Mr. William Gross, Chief Investment Officer and Managing Director of
Pacific Investment Management Company, and Mr. Poovey the terms outlining a
possible transaction with Allianz AG. The proposal contemplated the purchase
for cash of all of the interests in PIMCO Advisors other than those indirectly
beneficially owned by PAM at a unit price in the range of $36.

   On July 7, 1999, the press first reported that discussions about a potential
transaction were occurring between PIMCO Advisors and Allianz AG. The day
before the press report, the closing price of the Partnership units was $29.56
per unit.

   On July 13, 1999, the Partnership, PIMCO Advisors and Allianz AG entered
into a confidentiality agreement, contemplating the exchange of confidential
financial and operating information between the parties.

   On July 14 and 15, 1999 Dr. Diethart Breipohl, Chief Financial Officer and a
Member of the Board of Management of Allianz AG, and Dr. Faber met with Mr.
Gross, Mr. Thompson, three other managing directors of Pacific Investment
Management Company and Mr. Poovey in New York City, to discuss, among other
items, the organization of the management of Allianz AG fixed income assets by
Pacific Investment Management Company and issues related to the restructuring
of Pacific Investment Management Company, including the terms of its management
after the Closing.

                                       39
<PAGE>

   On July 24 and 25, 1999, Mr. Poovey met in Munich with Dr. Faber to review
and discuss the possible integration of the companies' respective asset
management businesses and the challenges that presented.

   On July 29, 1999, Allianz AG delivered to Partners LLC summary initial terms
for a proposed transaction. The proposal contemplated the acquisition for cash
of all interests of PIMCO Advisors other than those beneficially owned by PAM
at a unit price in the range of $36 for a total ownership of approximately 70%,
acquisition of control over Partners GP through the purchase of Partners LLC on
substantially the terms finally agreed (although based on a $36 unit price),
the satisfaction of the 1994 Employment Termination Agreements at that unit
price paid in cash and Allianz AG stock, a retention and bonus pool for
employees of PIMCO Advisors and its subsidiaries of $100 million per year for
five years, the management of Allianz AG fixed income assets by Pacific
Investment Management Company resulting in an estimated $10 million annual
contribution to the PIMCO Profit Sharing Plan, and suggested a reduction in the
PIMCO Profit Sharing Plan to 30% of profits funded by a ten year buy down
program.

   On July 30, 1999, representatives of Lazard Freres made a presentation to
Messrs. Thompson and Gross, certain other managing directors of Pacific
Investment Management Company and Mr. Poovey. The presentation reviewed the
transaction structure proposed by Allianz AG in which Allianz AG would acquire
approximately 70% of the interests in PIMCO Advisors, including all of the
interests in the Partnership. In addition, the presentation provided a
preliminary valuation analysis of the transaction, including an analysis of
historical financial results for PIMCO Advisors, market performance of
Partnership units, comparison of other merger and acquisition transactions
including premiums paid and analysis of transaction valuations. The
presentation is described in more detail under "--Other Information
Considered--Lazard Freres."

   On August 3, 1999, Dr. Breipohl, Dr. Faber, Dr. Helmut Wimmer, Director of
Participations of Allianz AG, and a representative of Putnam Lovell met with
Messrs. Thompson, Gross and Poovey and a representative of Lazard Freres in
London to continue to discuss the economic terms of the transaction proposed by
Allianz AG. Differences included the unit price ($36 vs. $40), the terms of
changes to the PIMCO Profit Sharing Plan and proposed terms of executive
retention payments.

   On August 24, 1999, representatives of Lazard Freres made another
presentation to Mr. Thompson, certain other managing directors of Pacific
Investment Management Company and Mr. Poovey. The presentation provided an
overview of the fixed income assets managed by Allianz group, including
insurance assets, third party retail assets and third party institutional
assets. In addition, the presentation analyzed the pro forma impact of these
assets on the financial performance of Pacific Investment Management Company.
The presentation also analyzed the current proposal for the proposed
transaction by comparing the quality of earnings from insurance assets. The
presentation concluded by examining various potential alternatives to certain
aspects of the terms of the transaction proposed by Allianz AG and the impact
such alternatives would have on the investment advisory fee revenues of PIMCO
Advisors.

   Commencing on August 24, 1999, a data room was set up at the offices of
Lazard Freres which permitted Allianz AG to begin the due diligence process.
PIMCO Advisors provided Allianz AG with information about all aspects of its
business and permitted the Allianz AG due diligence team to interview various
members of the management of PIMCO Advisors.

   In late August and early September 1999, there were numerous conference
telephone calls and meetings with representatives of PIMCO Advisors, Pacific
Investment Management Company and Allianz AG and their respective financial
advisors to discuss the transaction structure. PAM and its

                                       40
<PAGE>

legal advisors participated in one of these meetings in August, and PAM was
updated on the status of discussions by PIMCO Advisors. During this period,
representatives of PIMCO Advisors had tentative discussions with other
potential candidates for a business combination that did not result in any firm
offers.

   On August 25, 1999, Pacific Life, the indirect parent corporation of PAM,
and Goldman, Sachs & Co. ("Goldman Sachs") agreed that Goldman Sachs would
provide Pacific Life with financial advisory services in connection with, among
other things, the possible sale of Pacific Life's interest in PIMCO Advisors.

   On September 17, 1999, Allianz AG delivered to Partners LLC a revised
outline of terms for a proposed transaction. The proposal contemplated the
acquisition for cash of all interests of PIMCO Advisors other than those
beneficially owned by PAM at a unit price in the range of $38 for a total
ownership of approximately 70%, acquisition of control over Partners GP through
the purchase of Partners LLC on substantially the terms finally agreed
(although based on a $38 unit price), the satisfaction of the 1994 Employment
Termination Agreements at that unit price paid in cash and Allianz AG stock,
initial terms of put and call arrangements for the interest of PAM that would
be retained following the proposed transaction, a refinement of the retention
and incentive arrangements for employees, allocated between Pacific Investment
Management Company and other PIMCO Advisors employees and having terms
substantially as finally agreed, more detail on the management of Allianz AG
fixed income assets by Pacific Investment Management Company including a
proposed fee schedule and a $10 million minimum annual contribution to the
PIMCO Profit Sharing Plan, a proposal regarding governance matters, and a
suggested reduction in the PIMCO Profit Sharing Plan to 30% of profits funded
by a ten year buy down program.

   On September 20, 1999, representatives of Lazard Freres made an additional
presentation to Mr. Thompson, other managing directors of Pacific Investment
Management Company and Mr. Poovey. The presentation provided an overview of
proposed terms of a transaction with Allianz AG, a preliminary valuation
analysis of the transaction, an analysis of the offer by Allianz AG and a
discussion of the fixed income assets under management of Allianz AG, including
insurance assets, which were being proposed to be managed by Pacific Investment
Management Company if the proposed transaction were consummated. The
preliminary valuation analysis analyzed the Partnership's historical market
performance, comparative premium analysis for comparable acquisitions, a
discounted cash flow analysis, a valuation analysis and analysis of the offer
at various prices. These internal meetings continued on September 21, 1999.

   On September 22 and 23, 1999, Dr. Faber and representatives of Putnam Lovell
met with Messrs. Thompson, Gross and Poovey and representatives of Lazard
Freres in Carmel, California to negotiate the remaining major open business
items. While open issues remained, in particular the issues of unit price and
the continuing investment of PAM in PIMCO Advisors, these meetings resulted in
a general understanding between PIMCO Advisors and Allianz AG as to the
resolution of most other business issues, including an understanding of most
governance and structural issues. Following these meetings the parties agreed
to begin drafting the transaction documents.

   From the middle of September to the October 31, 1999 signing of the merger
agreement, PAM and Allianz AG negotiated the terms of the put and call
arrangements relating to the interest to be retained by PAM. In particular, PAM
and Allianz AG discussed the prices at which the put or call rights could be
exercised by PAM or Allianz AG, the circumstances triggering the put or call
rights, and whether the put or call prices would be subject to maximum and
minimum prices.

                                       41
<PAGE>

   On October 4, 1999, in New York City, Messrs. Thompson, Gross and Poovey met
with Dr. Breipohl and Dr. Faber and each of their respective financial and
legal advisors to further discuss the structural terms of the proposed
transaction.

   On October 5, 1999, PAM and its legal advisors met with legal advisors to
Allianz AG to negotiate the terms of PAM's continuing investment in PIMCO
Advisors. Open business issues included the economic terms of the retained
interest, whether PAM's interest would remain as an interest held through PIMCO
Advisors' general partner or be held directly at the PIMCO Advisors level,
Allianz AG's desire to have flexibility to restructure the Partnership's retail
and equity asset management businesses, PAM's approval rights over significant
actions affecting the Partnership's fixed income asset management business, the
put and call arrangements and the circumstances under which the put and call
arrangements could be exercised by either PAM or Allianz AG. On that same day
the press reported discussions between Allianz AG and PIMCO Advisors for a
potential business combination. After the close of trading on the New York
Stock Exchange, the Partnership issued a press release and on the morning of
October 6, Allianz AG issued a press release as well, each of which confirmed
the existence of discussions between PIMCO Advisors and Allianz AG for a
possible business combination, and that the unit price discussions were between
$38 and $39 per unit.

   On October 8, 1999, PIMCO Advisors and the Partnership retained Salomon
Smith Barney as an additional financial advisor in connection with the merger
and the merger agreement to render its opinion as to the fairness, from a
financial point of view, of the consideration to be received by the public
holders of Partnership units and certain holders of Advisors Class A Units in
connection with the merger. While the Partnership had no reason to believe that
Lazard Freres would not provide a fairness opinion if requested by the
Partnership, the Partnership requested the opinion from Salomon Smith Barney
because it desired the view of a third party who had not been involved in the
negotiation and structuring of the transaction.

   During the week of October 11, 1999, PIMCO Advisors, PAM, Allianz AG and
their respective legal and financial advisors negotiated documentation for the
transaction. These negotiations were conducted by means of meetings among
certain participants at the offices of counsel to Allianz AG in New York during
the course of the week, and two videoconferences on October 12 and 15. These
negotiations addressed the open business items relating to the transactions,
including the terms of any possible indemnity to be given by PAM or the members
of Partners LLC to Allianz AG for certain breaches under the merger agreement.

   On October 22, 1999, at a regularly scheduled meeting of the board of
directors of PMHC, the ultimate parent corporation of PAM, senior management
and PMHC's financial advisor, Goldman Sachs, and legal advisor, Gibson, Dunn &
Crutcher LLP, discussed with the board of directors the following:

  .  The status of the negotiations with respect to the proposed
     transactions, including the negotiations with respect to PMHC's
     ownership in the Partnership and PIMCO Advisors;

  .  The principal terms and conditions of the merger agreement and related
     transaction documents;

  .  The potential benefits and risks to the non-PMHC unitholders associated
     with the sale of control of the Partnership to Allianz AG; and

                                       42
<PAGE>

  .  The potential benefits and risks associated with PMHC's continued
     ownership in PIMCO Advisors in a non-control position.

   On October 22, 1999, McLagan Partners, Inc., management compensation
consultants, were retained to analyze and opine upon the reasonableness of the
proposed retention incentive arrangements being provided to executives of
Pacific Investment Management Company in the proposed transaction.

   During the week of October 25, 1999, the parties and their legal and
financial advisors met in Newport Beach, California to negotiate documentation
for the transaction, including the documentation relating to PAM's retained
interest in PIMCO Advisors. On October 29, 1999, representatives of Allianz AG
and our general partner agreed on a unit price of $38.75 for the proposed
transaction, subject to satisfactory completion of definitive documentation and
receipt of necessary board and general partner approvals.

   PMHC's board of directors held a special meeting on October 29, 1999, at
which senior management updated the board of directors on the status of
negotiations relating to the terms and conditions of the merger agreement and
related transaction documents, including the documentation relating to PAM's
retained interest in PIMCO Advisors. The board of directors also received a
financial presentation of Salomon Smith Barney regarding the financial terms of
the proposed transaction. See "--Opinion of Our Financial Advisor" for a
summary of the material financial analyses included in Salomon Smith Barney's
financial presentation and a description of the material information and
materials reviewed by Salomon Smith Barney in connection with its presentation.
Additionally, the Partnership's management reported to the PMHC board of
directors that the Partnership, Partners GP and Partners GP's partners had
received an opinion of McLagan Partners, Inc., which concluded that the
retention incentive arrangements being provided to executives of Pacific
Investment Management Company contemplated by the proposed transaction were
reasonable in light of industry practice and historical compensation of the
individuals. Goldman Sachs delivered its opinion that the consideration to be
received by PAM in exchange for the Advisors Class A Units beneficially owned
was fair to Pacific Life, from a financial point of view. At the special
meeting, the PMHC board of directors appointed a special committee comprised of
three outside directors and Thomas C. Sutton, Chairman of the Board of
Directors and Chief Executive Officer, which was authorized to approve the
final terms of the proposed transactions on behalf of PMHC's subsidiaries.

   On October 29, 1999, the members and management board of Partners LLC, the
managing general partner of Partners GP, including Mr. Thompson, Mr. Gross and
the other managing directors of Pacific Investment Management Company who had
been participating in the negotiations of the proposed transaction, held a
meeting to discuss the status of negotiations and the principal terms and
conditions of the merger agreement and the related transaction documents. At
the meeting, Lazard Freres made a presentation which summarized in detail the
terms of the proposed transaction between PIMCO Advisors and Allianz AG.
Salomon Smith Barney presented their fairness opinion, made a financial
presentation regarding the financial terms of the proposed transaction and
reviewed with the general partners of the Partnership and PIMCO Advisors a
financial and comparative analysis of the Partnership and PIMCO Advisors. The
presentation of Salomon Smith Barney included an overview of the transaction, a
general discussion of PIMCO Advisors, comparative operating performance of
similar companies and a valuation of PIMCO Advisors. See "--Opinion of Our
Financial Advisor" for a summary of the material financial analyses included in
Salomon Smith Barney's financial presentation and a description of the material
information and materials reviewed by Salomon Smith Barney in connection with
its presentation. The general partner was also presented with and considered
the opinion of McLagan Partners, Inc. analyzing the reasonableness of the
retention incentive arrangements being provided to the executives of Pacific
Investment Management Company in the proposed transaction. In addition to the
members and

                                       43
<PAGE>

management board of Partners LLC, representatives of PHLLC, Mr. Thomas Sutton,
Chairman and Chief Executive Officer of Pacific Life, Mr. Schafer, President of
Pacific Life, and two members of the special committee of the Board of
Directors of PMHC were in attendance during the portion of the meeting in which
the presentation of Salomon Smith Barney was made.

   After discussion, the management board of Partners LLC, constituting all of
its members, approved the merger agreement, the merger and the other
transactions contemplated by the merger agreement and authorized management to
finalize the terms of the transaction documents and authorized the Partnership
and PIMCO Advisors to enter into the merger agreement and to submit the merger
agreement and the merger to the Partnership's unitholders for approval.

   On October 31, 1999, the special committee of the PMHC board of directors
reconvened to continue its consideration of the proposed transactions. The
special committee received presentations from PMHC's senior management and
PMHC's legal advisors regarding the proposed final terms and conditions of the
merger agreement and related transaction documents. After discussion and due
consideration, the special committee of the PMHC board of directors unanimously
approved the merger agreement, the merger and the other transactions
contemplated by the merger agreement on behalf of the relevant PMHC
subsidiaries and authorized management to finalize the terms of the transaction
documents.

   On October 31, 1999, Partners LLC and PHLLC, on behalf of Partners GP and
for the Partnership and PIMCO Advisors, approved the merger agreement and the
related transactions. On October 31, 1999, the Supervisory Board of Allianz AG
approved the merger, the merger agreement and the other transactions
contemplated by the merger agreement. Following these approvals, the merger
agreement was signed and press releases announcing the transaction were issued.

                        Opinion of Our Financial Advisor

   Salomon Smith Barney has acted as a financial advisor to the Partnership and
PIMCO Advisors in connection with the merger of the Partnership with a
subsidiary of Allianz of America and the related transactions described in this
proxy statement. In connection with the engagement, Salomon Smith Barney
rendered an oral opinion to the general partners of the Partnership and of
PIMCO Advisors (the "General Partners") on October 29, 1999 to the effect that,
as of such date and based upon and subject to the factors and assumptions set
forth in the presentation, (i) the consideration to be received in the merger
by the holders of Partnership units, other than Excluded Holders (as defined
below), (the "Partnership Covered Units"), was fair, from a financial point of
view, to such holders, and (ii) the consideration to be received in the related
transactions by the holders of Advisors Class A Units, other than Excluded
Holders, (the "Advisors Covered Units"), was fair, from a financial point of
view, to such holders. For purposes of such opinion, "Excluded Holders" means
Pacific Life Insurance Company and each of its affiliates (including those
entities holding Advisors Class A Units underlying the 1994 Employment
Termination Agreements (the "ETA Units")), Partners LLC, Partners GP and each
of the managing directors of Pacific Investment Management Company (including
any units held for the benefit of such persons). Salomon Smith Barney
subsequently confirmed its oral opinion by delivery of a written opinion dated
October 29, 1999.

   Salomon Smith Barney's opinion, and the presentation of Salomon Smith Barney
to the General Partners, was only one of many factors taken into consideration
by the General Partners in making their determination to approve the merger and
the related transactions. The terms of the merger and the

                                       44
<PAGE>

related transactions were determined through negotiations among PIMCO Advisors,
the Partnership, PAM and Allianz AG, and were approved by the General Partners.
In connection with the preparation of Salomon Smith Barney's opinion, Salomon
Smith Barney was not engaged by the Partnership or PIMCO Advisors to solicit
third-party indications of interest for the acquisition of all or any part of
the Partnership or PIMCO Advisors. The decision to enter into the merger and
the related transactions and to accept the consideration to be paid to holders
of Partnership Covered Units and Advisors Covered Units, as contemplated in the
merger agreement, was solely that of the General Partners and Salomon Smith
Barney did not recommend the amount of consideration to be paid in the merger.

   The full text of Salomon Smith Barney's opinion, which sets forth the
assumptions made, general procedures followed, matters considered and
limitations on the review undertaken by Salomon Smith Barney, is included as
Annex B to this Proxy Statement. Salomon Smith Barney's opinion should be read
carefully and in its entirety. Salomon Smith Barney's opinion is directed only
to the fairness, from a financial point of view, of the consideration to be
received in the merger and the related transactions by the holders of
Partnership Covered Units and Advisors Covered Units to such holders, and it
does not address the underlying business decision to effect the merger and the
related transactions. It was provided for the information of the Partnership,
PIMCO Advisors, Partners GP, Partners LLC and PHLLC in the evaluation of the
merger and the related transactions, and is not intended to be and does not
constitute a recommendation to any holder of Partnership units or Advisors
Class A Units as to how such holder should vote on any matters relating to the
merger and the related transactions. The summary of Salomon Smith Barney's
opinion set forth in this Proxy Statement is qualified in its entirety by
reference to the full text of Salomon Smith Barney's opinion.

   In connection with rendering its opinion, Salomon Smith Barney:

  .  reviewed the October 27, 1999 draft of the merger agreement (including
     its exhibits) in the form provided to Salomon Smith Barney, and took
     into account the terms of the merger and the related transactions set
     forth therein, including the terms of PAM's continuing investment in
     PIMCO Advisors, as described in "--Financial Interests of Certain
     Persons in the Transaction--Partners GP--PHLLC and PAM," and the
     incentive and retention payments being made pursuant to the merger
     agreement, as described in "--Financial Interests of Certain Persons--
     Partners GP--Partners LLC;"

  .  reviewed certain publicly available business and financial information
     that Salomon Smith Barney deemed relevant relating to the Partnership,
     PIMCO Advisors and the industries in which they operate, including
     information with respect to assets under management and allocation among
     products, types of clients served, historical asset inflows and product
     performance;

  .  reviewed certain internal non-public financial and operating data and
     other information provided to Salomon Smith Barney by the management of
     the Partnership and PIMCO Advisors relating to the Partnership's and
     PIMCO Advisors' respective businesses, including certain forecast and
     projection information as to the future financial results of such
     businesses, see "Certain Financial Projections."

  .  reviewed certain publicly available business and financial information
     with respect to certain other companies Salomon Smith Barney believed to
     be relevant or comparable in certain respects to the Partnership and
     PIMCO Advisors, including information with respect to assets under
     management and allocation among products, types of clients served,
     historical asset inflows and product performance, and the trading
     markets for such other companies' securities;

                                       45
<PAGE>

  .  reviewed and analyzed certain publicly available and other information
     concerning the trading of, and the trading market for, the Partnership
     units;

  .  reviewed the financial terms (including arrangements with management and
     controlling persons to the extent publicly available) of certain
     business combinations and acquisition transactions that Salomon Smith
     Barney deemed reasonably comparable to the merger and the related
     transactions and otherwise relevant to Salomon Smith Barney's inquiry;

  .  discussed with members of senior management and other officers,
     employees and representatives of the Partnership and PIMCO Advisors the
     foregoing, including the past and current business operations, financial
     condition and prospects of the Partnership and PIMCO Advisors; and

  .  considered such other information, financial studies, analyses,
     investigations and financial, economic, market and trading criteria as
     Salomon Smith Barney deemed relevant to its inquiry.

   In its review and analysis and in arriving at its opinion, Salomon Smith
Barney assumed and relied upon, without assuming any responsibility for
verification, the accuracy and completeness of all of the financial and other
information provided to, discussed with, or reviewed by or for Salomon Smith
Barney, or publicly available. Salomon Smith Barney also assumed that the final
form of the merger agreement (including its exhibits) would not vary in any
respect that is material to Salomon Smith Barney's analysis from the last draft
reviewed by Salomon Smith Barney. With respect to the financial projections for
PIMCO Advisors and the Partnership provided to, discussed with or reviewed for
Salomon Smith Barney by the management of PIMCO Advisors or the Partnership,
respectively (the "Projections"), Salomon Smith Barney was advised by
management of PIMCO Advisors and the Partnership, respectively, and Salomon
Smith Barney assumed, that such Projections were reasonably prepared on bases
reflecting the best currently available estimates and judgments on the part of
management of PIMCO Advisors or the Partnership, as applicable, as to the
future financial performance of PIMCO Advisors or the Partnership, as
applicable. Salomon Smith Barney expressed no view as to such Projections or
information or the assumptions on which they were based. Salomon Smith Barney
also assumed, based upon discussions with management of PIMCO Advisors and the
Partnership, that the combined value of the cash and common shares of Allianz
AG to be received with respect to each ETA Unit pursuant to the merger
agreement is equal to the Unit Price to be received by holders of Partnership
Covered Units and Advisors Covered Units.

   Salomon Smith Barney did not assume any responsibility for making or
obtaining any independent evaluations or appraisals of any of the assets or
liabilities of the Partnership or PIMCO Advisors, nor for conducting a physical
inspection of the properties and facilities of the Partnership or PIMCO
Advisors, and Salomon Smith Barney was not furnished with any such evaluation
or appraisal. Salomon Smith Barney relied upon counsel to the Partnership and
PIMCO Advisors with respect to interpretations of the provisions contained in
the constituent documents and related agreements of the Partnership and PIMCO
Advisors and the application of applicable law to such documents and
agreements. Salomon Smith Barney's opinion necessarily was based on market,
economic and other conditions as they existed and could be evaluated on October
29, 1999, and Salomon Smith Barney assumed no responsibility to update or
revise its opinion based upon circumstances or events occurring after October
29, 1999.

   In connection with rendering its opinion to the General Partners, Salomon
Smith Barney performed a variety of financial analyses, the material portions
of which are summarized below. The

                                       46
<PAGE>

summary of such analyses set forth below does not purport to be a complete
description of the analyses underlying Salomon Smith Barney's opinion or of
Salomon Smith Barney's presentation to the General Partners. In addition,
Salomon Smith Barney believes that its analyses must be considered as a whole
and that selecting portions of such analyses and the factors considered
therein, without considering all such analyses and factors, could create an
incomplete view of the analyses and the process underlying Salomon Smith
Barney's opinion. While the conclusions reached in connection with each
analysis were considered carefully by Salomon Smith Barney in arriving at
Salomon Smith Barney's opinion, Salomon Smith Barney made various subjective
judgments in arriving at its opinion and did not consider it practicable to,
nor did it attempt to, assign relative weights to the individual analyses and
specific factors considered in reaching its opinion.

   The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In
addition, the process of preparing a fairness opinion necessarily requires a
broad range of subjective judgments with respect to appropriate comparable
companies and transactions, appropriate multiples of various selected financial
data, appropriate discount rates and other financial and other factors.
Analyses and estimates of the values of companies do not purport to be
appraisals or necessarily reflect the prices at which companies or their
securities actually may be sold. No public company utilized as a comparison is
identical to the Partnership or PIMCO Advisors, and none of the other
transactions utilized as a comparison is identical to the proposed merger and
related transactions. Accordingly, any analysis of publicly traded comparable
companies or comparable transactions is not mathematical; rather, it involves
complex considerations and judgments concerning differences in financial and
operating characteristics of the companies involved and other factors that
could affect the public trading value of the companies or company to which they
are being compared. The range of valuation for any particular analysis should
not be taken to be the view of Salomon Smith Barney of the actual value of the
Partnership or PIMCO Advisors. In its analyses, Salmon Smith Barney made
numerous assumptions with respect to the Partnership and PIMCO Advisors,
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of the
Partnership and PIMCO Advisors. The estimates contained in such analyses and
the valuation ranges resulting from any particular analysis are not necessarily
indicative of actual values or predictive of future results or values, which
may be significantly more or less favorable than those suggested by such
analyses.

Financial Analyses

   The following is a summary of the material financial analyses performed by
Salomon Smith Barney in connection with its opinion dated October 29, 1999.

   Normalized Price Analysis. As an initial step in its analysis, Salomon Smith
Barney considered the market price per Partnership unit as of July 1, 1999,
five business days before the first public statement by Allianz AG regarding a
potential transaction between Allianz AG and the Partnership, and found such
price to be $29.38.

   So as to be able to compare the implied valuation ranges resulting from the
various financial analyses set forth below to a Partnership unit value that
excluded the effects of speculation regarding the terms and timing of a
potential transaction, Salomon Smith Barney selected a group of publicly traded
investment advisors that it considered to be comparable to the Partnership as a
"control group," and examined the changes in their per share market prices for
the period from July 1, 1999 until October 28, 1999 (the day before Salomon
Smith Barney rendered its opinion to the General Partners). Salomon Smith
Barney calculated the average change in price for the members of such

                                       47
<PAGE>

control group over that period, weighted by market capitalization, and found
that average to be a decline of 15.7%. Applying such percentage decline to the
market price per Partnership unit as of July 1, 1999, Salomon Smith Barney
obtained a "normalized" price per Partnership unit of $24.38, which it
considered to be a reasonable approximation of the price per Partnership unit
that might have been expected to exist on October 28, 1999 absent public
statements regarding a potential transaction.

   In considering the results of its various financial analyses set forth
below, Salomon Smith Barney compared the implied valuation ranges resulting
from such analyses to the actual price per Partnership unit as of July 1, 1999
of $29.38, the actual price per Partnership unit price as of October 28, 1999
of $34.13, and the "normalized" price per Partnership unit as of October 28,
1999 of $24.38. For the purposes of the public market comparable company
analysis and precedent transaction analysis described below, Salomon Smith
Barney determined implied valuation ranges for Advisors Class A Units (rather
than Partnership units) because Advisors Class A Units are the only material
asset of the Partnership, and the Advisors Class A Units have a greater value
than Partnership units as a result of the excise taxes payable by the
Partnership with respect to its share of PIMCO Advisors' revenues. In the case
of the discounted cash flow analysis described below, Salomon Smith Barney
performed separate valuations with respect to Advisors Class A Units and
Partnership units so as to specifically take into account the excise taxes
payable by the Partnership by analyzing the value of projected cash flows to be
received by holders of the respective units.

   Public Market Comparable Company Analysis. Using publicly available
information, Salomon Smith Barney analyzed, among other things, the operating
performance and market valuation of three groups of publicly traded investment
advisors considered by Salomon Smith Barney to be comparable to PIMCO Advisors
and the Partnership. In order to analyze market valuation, Salomon Smith Barney
calculated a variety of trading multiples, including firm value as a percentage
of assets under management ("AUM") and as a multiple of last twelve months
("LTM") revenues and earnings before interest, taxes, depreciation and
amortization ("EBITDA"), and market value as a multiple of LTM cash flow and
earnings, and as a multiple of estimated 1999 and 2000 earnings per share (as
provided by I/B/E/S).

   The first group utilized by Salomon Smith Barney consisted of broadly
comparable "pure play" investment advisors organized as taxable corporations
(the "Taxable Peer Group"), and included Affiliated Managers Group, Inc.,
AMVESCAP Plc, BlackRock, Inc., Eaton Vance Corp., Federated Investors, Inc.,
Franklin Resources, Inc., Gabelli Asset Management Inc., The John Nuveen
Company, Neuberger Berman Inc., Phoenix Investment Partners, Ltd., T. Rowe
Price Associates, Inc., United Asset Management Corporation and Waddell & Reed
Financial, Inc. The second group consisted of investment advisors organized as
taxable corporations whose businesses or growth characteristics more closely
resembled those of PIMCO Advisors (the "Selected Peer Group"), and included
BlackRock, Inc., Phoenix Investment Partners, Ltd., T. Rowe Price Associates,
Inc. and Kansas City Southern Industries, Inc. The third group consisted of
investment advisors organized as master limited partnerships (the "MLP Peer
Group"), and included Alliance Capital Management Holding L.P. and Nvest, L.P.

   Using the comparable operating data for PIMCO Advisors, Salomon Smith Barney
calculated the implied valuation range for Advisors Class A Units based upon
the average multiple for each of the measures of value described above, and the
average of such implied valuation ranges for each Advisors Class A Unit.

   Based upon such analysis and assuming net indebtedness of approximately $98
million and 120.3 million diluted Advisors Class A Units outstanding, Salomon
Smith Barney determined an

                                       48
<PAGE>

implied valuation range of $21.04 to $25.78 per Advisors Class A Unit using the
Taxable Peer Group, $22.92 to $25.19 per Advisors Class A Unit using the
Selected Peer Group, and $17.86 to $21.90 per Advisors Class A Unit using the
MLP Peer Group.

   Precedent Transaction Analysis. Salomon Smith Barney reviewed publicly
available information with respect to 13 precedent transactions occurring from
1994 to 1999 involving the acquisition of investment advisors that were
considered by Salomon Smith Barney to be comparable to PIMCO Advisors with
respect to size and/or business mix. For each such precedent transaction,
Salomon Smith Barney calculated a variety of transaction multiples, including
firm value as a percentage of AUM and as a multiple of LTM revenues and EBITDA,
and equity value as a multiple of LTM pre-tax income and earnings.

   Using the comparable data for PIMCO Advisors, Salomon Smith Barney
calculated the implied valuation range for Advisors Class A Units based upon
the average multiple for each of the measures of value described above, and the
average of such implied valuation ranges for each Advisors Class A Unit. Based
upon such analysis, Salomon Smith Barney determined an implied valuation range
for each Advisors Class A Unit of $29.24 to $35.84.

   Discounted Cash Flow Analysis. Based on the Projections, Salomon Smith
Barney performed a discounted cash flow ("DCF") analysis on PIMCO Advisors to
determine an implied valuation range for each Advisors Class A Unit, based on
discounting (1) projected distributions for five years ending in 2004 and (2) a
terminal value based on projected 2004 distributions.

   Salomon Smith Barney first reviewed a "base case" scenario assuming a
discount rate of 13% and a 9.0x terminal value multiple. In addition, Salomon
Smith Barney reviewed the sensitivity of such analysis by calculating the value
of each Advisors Class A Unit assuming a range of discount rates from 11% to
16%, and a range of terminal value multiples from 7.0x to 11.0x.

   Based upon such analysis, Salomon Smith Barney determined the following base
case implied value per Advisors Class A Unit and implied valuation range per
Advisors Class A Unit based on the sensitivity analysis:

<TABLE>
<CAPTION>
                                         Implied Value per Advisors Class A Unit
                                         ---------------------------------------
   <S>                                   <C>
   Base Case............................             $36.98
   Sensitivity Analysis.................             $28.41 - $45.74
</TABLE>

   In order to analyze the effect of the excise taxes payable by the
Partnership with respect to its share of PIMCO Advisors' revenues, Salomon
Smith Barney also performed a separate DCF analysis with respect to the
Partnership. This analysis was based on the same methodology and discount rates
as used for PIMCO Advisors, but used projected distributions by the Partnership
rather than PIMCO Advisors, and increased the terminal value multiples to
reflect the higher multiple of LTM distributions represented by a specific unit
price. The Partnership base case analysis used a 10.0x terminal value multiple,
and the Partnership sensitivity analysis used a range of terminal value
multiples from 8.0x to 12.0x.

   Based upon such analyses, Salomon Smith Barney determined the following base
case implied value per Partnership unit and implied valuation range per
Partnership unit based on the sensitivity analysis:

<TABLE>

   Retained Pacific Life Units. In connection with rendering its opinion,
Salomon Smith Barney took into account the terms of the merger and the related
transactions set forth in the merger agreement (including its exhibits),
including the terms of PAM's continuing investment in PIMCO Advisors.

   As discussed in more detail under "--Financial Interests of Certain Persons
in the Transaction--Partners GP--PHLLC and PAM," PAM will exchange the Advisors
Class A Units currently held by certain of its affiliates (other than the ETA
Units) for newly issued Class E Units (the "Retained Units"). The Retained
Units will be entitled to receive cash distributions which, on an annual basis,
in the aggregate, will equal: (1) a "variable component" equal to 20% of
Pacific Investment Management Company's adjusted operating profit available for
distribution, and (2) a "fixed component" equal to $1.05 per annum per Advisors
Class A Unit previously beneficially owned by PAM. Based upon discussions with
management of PIMCO Advisors and the Partnership, Salomon Smith Barney assumed
that the variable component, which was defined to include only the fixed-income
portion of PIMCO Advisors' existing business, would not be materially impacted
by the merger and the related transactions, and that the fixed component is
substantially equivalent to the historical distributions from PIMCO Advisors'
retail and equity asset management business that will be excluded for purposes
of calculating the variable component described above.

   In addition, pursuant to certain purchase and sale arrangements with Allianz
of America, at any time following the Closing, PAM will have the right to
require Allianz of America to purchase all of the Retained Units at a per-unit
price equal to (1) 14.0 (which was based upon the multiple of projected 1999
distributions per Advisors Class A Unit represented by the Unit Price),
multiplied by (2) LTM distributions made with respect to such unit (the "Put
Price"), subject to a maximum price of $60.00 per unit previously beneficially
owned by PAM. In addition, at any time after December 31, 2002, Allianz of
America will have the right to purchase all of the Retained Units at a price
per unit equal to the Put Price, provided that the Put Price is greater than
$50.00 per unit previously beneficially owned by PAM. In the event of a change
of control of PMHC, Allianz of America will have the right to purchase all of
the Retained Units at the end of the year in which the change of control occurs
at a price per unit equal to the higher of the Put Price and the Unit Price.

   Salomon Smith Barney performed a DCF analysis by calculating the net present
value of projected distributions with respect to each Retained Unit. The base
case DCF assumed 7.5% annual growth in Pacific Investment Management Company's
pre-bonus profits, a 15% discount rate with respect to the variable component
of the distributions, and the purchase of the Retained Units by Allianz of
America at the end of 2002, the first opportunity for Allianz of America to
purchase such Retained Units absent a change of control of PMHC. In addition,
Salomon Smith Barney reviewed the sensitivity of such analysis by calculating
the value of such units assuming growth in Pacific Investment Management
Company's adjusted net profit ranging from 2.5% to 20%, discount rates ranging
from 11% to 19% for the variable component, and year of purchase ranging from
2000 to 2004. The fixed component of the distributions was discounted using a
7% discount rate in all scenarios. Salomon Smith Barney used a higher discount
rate for the variable component of the projected distributions so as to take
into account the increased business and market risk associated with such
variable component relative to the fixed component.

   Based upon such DCF analysis, Salomon Smith Barney determined the following
base case implied value per Retained Unit and implied valuation range per
Retained Unit based on the sensitivity analysis:

<TABLE>
<CAPTION>
                                                 Implied Value per Retained Unit

   Base Case....................................         $38.91
   Sensitivity Analysis.........................         $36.91 - $52.99
</TABLE>

   In considering the results of the above analysis, based upon discussions
with management of PIMCO Advisors, Salomon Smith Barney assumed that the
agreement of PAM was required in order to structure the transactions
contemplated by the merger agreement so as to enable Allianz AG to achieve more
favorable tax treatment with respect to the purchase of the ETA Units and
certain Advisors Class A Units underlying employee options ("Option Units"),
and that the incremental value to Allianz AG of such favorable tax treatment is
approximately $4 per ETA Unit and Option Unit (or approximately $2 per Advisors
Class A Unit owned by PAM and its affiliates for their own accounts.)

   Salomon Smith Barney is an internationally recognized investment banking
firm that regularly engages in the valuation of companies and their securities
in connection with mergers and acquisitions, negotiated underwritings,
competitive bids, secondary distributions of listed and unlisted securities,
and corporate, estate and other purposes. The Partnership and PIMCO Advisors
retained Salomon Smith Barney as a financial advisor because of its reputation,
expertise in the valuation of companies, substantial experience in transactions
such as those contemplated by the merger agreement and familiarity with the
investment management industry.

   Salomon Smith Barney, in the ordinary course of business, has from time to
time provided, and in the future may continue to provide, investment banking,
financial advisory and other related services to the Partnership, PIMCO
Advisors, Pacific Life, Allianz AG and/or their respective affiliates, as the
case may be, for which it has received or will receive fees. In addition, in
the ordinary course of business, Salomon Smith Barney or its affiliates may
trade in the debt and equity securities of the Partnership, Allianz AG and/or
their respective affiliates, as the case may be, for its own account and for
the accounts of its customers and, accordingly, may at any time hold a long or
short position in such securities. In addition, Salomon Smith Barney or its
affiliates serve as investment subadviser and/or distributor for certain
registered investment companies sponsored by affiliates of the Partnership and
receive customary fees for such service, and Salomon Smith Barney and its
affiliates (including Citigroup Inc. and its affiliates) may maintain other
business relationships with the Partnership, PIMCO Advisors, Allianz AG and/or
their respective affiliates.

   Pursuant to the terms of Salomon Smith Barney's engagement, the Partnership
and PIMCO Advisors paid Salomon Smith Barney a fee of $2,000,000 for the
delivery of Salomon Smith Barney's opinion to the General Partners, and have
agreed to reimburse Salomon Smith Barney for its reasonable travel and other
out-of pocket expenses incurred in connection with its engagement (including
the reasonable fees and disbursements of its counsel), and to indemnify Salomon
Smith Barney and certain related persons against certain liabilities, including
liabilities under the federal securities laws, arising out of Salomon Smith
Barney's engagement.

                          Other Information Considered

Lazard Freres & Co. LLC

   Early in our discussions with Allianz AG, the Partnership retained Lazard
Freres to assist us in analyzing the proposed transaction. The Partnership
selected Lazard Freres because of its knowledge of our business (we have worked
with them in the past) and its expertise and its reputation in investment
banking and mergers and acquisitions. Lazard Freres is an internationally
recognized investment banking firm and is continually engaged in the valuation
of businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, secondary distributions of listed and unlisted
securities, private placements, leveraged buyouts and valuations for real
estate, corporate and other purposes.

   As described in this proxy statement under "--Background of the
Transaction," representatives of Lazard Freres participated in a number of
meetings regarding the Allianz AG discussions, and provided financial and
comparative analyses of the proposed transaction as it evolved. Lazard Freres
was not requested to and did not render an opinion, appraisal or report with
respect to the proposed transaction.

   The following is a summary of the material financial and comparative
analyses performed by Lazard Freres in connection with the merger and the
subsequent transactions. A copy of each presentation delivered by Lazard Freres
has been filed as an exhibit to the Schedule 13E-3 filed with the Commission by
PAM, Pacific Life, PHLLC, Partners LLC, Partners GP and the Partnership and is
available for inspection and copying at the principal executive offices of the
Partnership during its regular business hours by any unitholder or such
unitholder's representative who has been so designated in writing, upon written
request and at the expense of the requesting unitholder or representative.

   In formulating its analyses, Lazard Freres assumed and relied upon, without
independent verification, the accuracy and completeness of all information
publicly available or reviewed by or discussed with Lazard Freres. Lazard
Freres did not independently value or appraise the assets or liabilities of
PIMCO Advisors and did not assume any responsibility for matters concerning the
solvency of or issues relating to the management of PIMCO Advisors, Allianz AG
or any other entity. Lazard Freres also relied upon the advice of management of
PIMCO Advisors that the financial forecasts and other information that were
provided to or discussed with Lazard Freres were reasonably prepared based on
the best currently available estimates and judgments of PIMCO Advisors'
management as to the future financial performance of PIMCO Advisors and
expressed no view as to such forecasts or the assumptions on which they were
based. If the proposed transactions are consummated, Lazard Freres will receive
$9.2 million in exchange for its services, of which a non-refundable retainer
of $950,000 has already been paid. Lazard Freres assisted the Partnership in
the structuring and analysis of the transactions from its inception. While the
Partnership had no reason to believe that Lazard Freres would not provide a
fairness opinion if requested by the Partnership, the Partnership requested a
fairness opinion from Salomon Smith Barney because it desired the view of a
third party who had not been involved in the negotiation and structuring of the
transactions.

July 30, 1999 Presentation

   On July 30, 1999, representatives of Lazard Freres made a presentation to
Messrs. Thompson and Gross, certain other managing directors of Pacific
Investment Management Company and Mr. Poovey. The presentation outlined the
proposed structure of a transaction based on the terms proposed by Allianz AG
on July 29, 1999, provided a preliminary valuation analysis of the proposed
transaction and concluded with an analysis of the fixed income assets of
Allianz AG.

                                       52
<PAGE>

   Proposed Transaction Overview. The presentation included an overview of the
terms of the transaction, including:

    .  the relative ownership of PIMCO Advisors following the merger and
       the subsequent transactions;

    .  the purchase price;

    .  the liquidation of the 1994 Employment Termination Agreements;

    .  the "buy down" of the Pacific Investment Management Company bonus
       pool;

    .  the retention and bonus incentives; and

    .  the management by Pacific Investment Management Company of assets
       currently managed by the Allianz group.

   For a more detailed discussion of the structure and terms of the merger and
the subsequent transactions, see "The Transaction."

   Financial Review of PIMCO Advisors. Following its discussion of the proposed
transaction, Lazard Freres provided a financial review of PIMCO Advisors,
setting forth PIMCO Advisors' historical assets under management ("AUM"), its
operations and balance sheet as well as the operating performance of PIMCO
Advisors by segment. The Lazard Freres presentation also set forth management's
projected financial performance of PIMCO Advisors through the year 2005.
Although these July projections reflected financial performance measures that
were generally 6% to 8% higher than those contained in the more recent
projections described under "Certain Financial Projections" because the July
projections were based on earlier financial information (third quarter results
were not then available), the Partnership believes these July projections are
substantially similar to the projections set forth under "Certain Financial
Projections." See page 77. The financial review concluded with the presentation
of a chart graphing the year-to-date market performance of the Partnership
units.

   Initial Valuation Analysis. Lazard Freres then presented an initial
valuation analysis of PIMCO Advisors. This preliminary analysis was intended to
provide a range of unit prices that holders of Partnership units and the
Advisors Class A Units might receive in a transaction involving a business
combination. The analysis focused on three different valuation methods: a
comparison of public company trading statistics, a comparison of recent mergers
and acquisitions and a discounted cash flow analysis. Lazard Freres also
provided an analysis of premium amounts paid in recent acquisition
transactions. A summary of the results of each of these analyses is set forth
below.

   Public Company Trading Statistics. Lazard Freres reviewed and compared the
actual financial, operating and stock market information of selected public
companies in lines of business believed to be generally comparable to those of
PIMCO Advisors. These companies included the master limited partnerships of
Alliance Capital Management Holding L.P. and Nvest, L.P., as well as Franklin
Resources, Inc., AMVESCAP PLC, T. Rowe Price Associates, Inc., Waddell & Reed
Financial, Inc., Federated Investors, Inc., The John Nuveen Company, Eaton
Vance Corporation, United Asset Management Corporation, Affiliated Managers
Group, Inc., Gabelli Asset Management Inc., Phoenix Investment Partners, Ltd.
and Conning Corporation.

   Specifically, Lazard Freres analyzed the respective multiples of the firm
values of these companies to their historical operating revenues, operating
income and AUM. Lazard Freres then derived a range of implied per unit equity
values for PIMCO Advisors by applying the multiples from the comparable

                                       53
<PAGE>

company analysis to corresponding data for PIMCO Advisors prepared by its
management. Lazard Freres then narrowed those ranges by focusing on the medians
of the high and low implied per share equity value ranges. The resulting
implied per unit equity value range was $30.50 to $35.25.

   Merger and Acquisition Transactions. Lazard Freres reviewed selected
publicly available financial and stock market information for the ten following
transactions involving the acquisition of entities in the financial services
industry with a product mix, growth, margin or other characteristics comparable
to those of PIMCO Advisors with transaction values ranging from $240 million to
over $5 billion:

  .  the acquisition of Frank Russell Company, valued at $950 million, by The
     Northwestern Mutual Life Insurance Company in August 1998;

  .  the acquisition of Chancellor LGT Management, Inc., valued at $1.15
     billion, by AMVESCAP PLC in January 1998;

  .  the acquisition of Mercury Asset Management Group, valued at $5.08
     billion, by Merrill Lynch & Co., Inc. in November 1997;

  .  the acquisition of Scudder, Stevens & Clark, valued at $1.66 billion, by
     Zurich Insurance Company in June 1997;

  .  the acquisition of Chancellor Capital Management, Inc., valued at $260
     million, by Liechenstein Global Trust, A.G. in July 1996;

  .  the acquisition of RCM Capital Management, valued at $390 million, by
     Dresdner Bank AG in January 1996;

  .  the acquisition of Miller Anderson & Sherrerd LLP, valued at $350
     million, by Morgan Stanley Group Inc. in June 1995;

  .  the acquisition of Brinson Partners Inc., valued at $870 million, by
     Swiss Bank Corporation in August 1994;

  .  the acquisition of BlackRock Financial Management L.P., valued at $240
     million, by PNC Bank Corp. in June 1994; and

  .  the acquisition of the Dreyfus Corporation, valued at $1.92 billion, by
     the Mellon Bank Corporation in December 1993.

   Lazard Freres analyzed the respective multiples of the transaction value for
these transactions to the historical operating income, revenues and AUM of the
selling firm. Lazard Freres then derived a range of implied per unit equity
values for PIMCO Advisors by applying the multiples from the precedent
transactions listed above to corresponding data for PIMCO Advisors prepared by
its management. Lazard Freres then narrowed those ranges by focusing on the
medians of the high and low implied per share equity value ranges. The
resulting implied per unit equity value range was $35.25 to $42.50.

   Discounted Cash Flow Analysis. Lazard Freres performed a discounted cash
flow analysis of management's projections of free cash flow of PIMCO Advisors
for the years ended December 31, 1999 through December 31, 2005. As part of its
analysis, Lazard Freres assumed, among other things, discount rates of 12% to
16%, and terminal multiples of the operating profits available for distribution
of 9.0x to 11.0x. Based on this analysis Lazard Freres then derived a range of
implied per unit equity values for PIMCO Advisors from $37.00 to $41.75.

   Lazard Freres also reviewed the publicly available information concerning
premiums paid in fourteen acquisition transactions of entities in the financial
services industry with transaction values ranging from $2 billion to $10
billion. Lazard Freres analyzed the information from these

                                       54
<PAGE>

transactions using three criteria: the purchase price as a percentage premium
of the one-day-prior trading price, the purchase price as a percentage premium
of the one-week-prior trading price and the purchase price as a percentage
premium of the four-weeks-prior trading price. Lazard Freres then derived a
range of implied per unit equity prices for PIMCO Advisors by applying the
premiums from the precedent transactions to the unit prices of PIMCO Advisors
Holdings. Lazard Freres then narrowed those ranges by focusing on the medians
of the high and low implied per share equity ranges. The resulting implied
equity value range was $38.50 to $41.50.

   In addition, the presentation noted the consideration proposed to be paid to
all holders of interests in the Partnership and PIMCO Advisors, which included
cash amounts to be paid to unitholders and in satisfaction of payments due
under the 1994 Employment Termination Agreements. Employing a hypothetical per
unit purchase price of $36 resulted in an aggregate implied consideration of
$4.3 billion. The presentation also stated the effect of combining that
aggregate unit based consideration with all amounts proposed to be paid as
retention and incentive amounts to management. This aggregation of purchase
price and other payments resulted in an equivalent per unit amount of $40.19,
for an aggregate consideration of $4.8 billion.

   Fixed Income Assets of the Allianz Group. The presentation concluded with a
discussion of the fixed income assets under management of the Allianz group,
including insurance assets, that were proposed to be managed by Pacific
Investment Management Company following the merger and the subsequent
transactions. The analysis concluded by setting forth a projection of the
increase in total income to Pacific Investment Management Company that could
occur as a result of its management of the Allianz group assets. As a result of
the management of these additional assets, it was estimated that the total
income of Pacific Investment Management Company might increase by $28.4 million
in the year 2000 and by $62.6 million in the year 2002.

August 24, 1999 Presentation

   On August 24, 1999, to assist PIMCO Advisors in its business due diligence
regarding fixed income assets managed by Allianz AG, representatives of Lazard
Freres made a presentation to Mr. Thompson, certain other managing directors of
Pacific Investment Management Company and Mr. Poovey. The report provided an
overview of the fixed income assets managed by Allianz group, including
insurance assets, third-party retail assets and third party institutional
assets. In addition, the presentation analyzed the pro forma impact of these
assets on the financial performance of Pacific Investment Management Company.
The potential contributions of these assets to Pacific Investment Management
Company vary as follows:

    .  for managing insurance assets, Pacific Investment Management Company
       would receive a base fee and be eligible for performance fees that
       increase as certain hurdles are obtained;

    .  for managing retail assets Pacific Investment Management Company
       would provide a model portfolio and receive subadvisory fees; and

    .  for third-party institutional assets inside and outside Germany,
       Pacific Investment Management Company would have an economic
       interest allowing for participation in the profits and losses of the
       business of managing those assets.

   The summary compared estimates of the expected economic impact of Allianz
AG's fixed income assets to estimates that were based on input from Pacific
Investment Management Company's management. For 1999, Allianz AG projected a
total income of $60.2 million; management projected

                                       55
<PAGE>

a total income within the range of $15.4 million to $23.9 million. For 2002,
Allianz AG projected a total income of $106.4 million; management projected a
total income within the range of $51.5 million to $61.9 million. The estimates
of the expected impact of Allianz AG's fixed income assets prepared by Allianz
AG and Pacific Investment Management Company differed primarily because of more
optimistic assumptions by Allianz AG of the amount of performance fees that
would be received by Pacific Investment Management Company as a result of
managing the fixed income assets of the Allianz group.

   As a result of this comparison of the projected contributions to Pacific
Investment Management Company, Lazard Freres identified several key issues
relating to the structure of the proposed management of the Allianz AG fixed
income assets by Pacific Investment Management Company. These issues included
the following:

    .  the base fees relating to the insurance assets would cover only the
       costs of Pacific Investment Management Company and therefore its
       profit would be highly sensitive to the performance fees;

    .  there is considerable uncertainty involved in estimating the
       performance fees, due in part, to the restrictions on investment of
       the insurance funds;

    .  the profits associated with the retail assets are based on the
       assumption that the model portfolio can be provided at no marginal
       cost; and

    .  Pacific Investment Management Company would have limited ability to
       control the costs of the European investment organizations.

   While the final terms of the proposed transactions did not address these
post-transaction operational issues and the uncertainties associated with these
issues remained, the general partner determined to proceed with the transaction
based on its analysis of the overall benefits of the transaction.

September 20, 1999 Presentation

   On September 20, 1999, representatives of Lazard Freres delivered an updated
version of its July 30, 1999 presentation to Messrs. Thompson and Poovey. The
presentation began by again summarizing the proposed terms and structure of the
transaction. Lazard Freres then presented a revised valuation analysis based on
figures updated through September 16, 1999. In addition, the presentation
provided a discussion of the fixed income assets under management of Allianz
AG, including insurance assets, which would be managed by Pacific Investment
Management Company if the proposed transaction were consummated.

   Valuation Analysis. In the September 20, 1999 presentation, Lazard Freres
updated each of the individual valuation analyses that it presented in its July
30, 1999 presentation. The Public Company Trading Statistics were updated to
include market information through September 16, 1999. The Mergers and
Acquisitions Transactions section was updated to include data on additional
transactions which provided additional comparative data. These transactions
were: the acquisition of M&G Investment Management, valued at $2.93 billion, by
Prudential in March 1999; the acquisition of AIM Management Group, valued at
$1.74 billion, by INVESCO PLC in November 1996; and the acquisition of Global
Asset Management, valued at $675 million, by Union Bank of Switzerland which
occurred in September 1999 after the preparation of the July presentation. The
Discounted Cash Flow Analysis section was refined to reflect updated
outstanding unit count and outstanding

                                       56
<PAGE>

indebtedness. The updated and additional information resulted in revised ranges
of per unit equity value for each of the different analyses. The chart below
sets forth the revised ranges of per unit equity value for PIMCO Advisors under
each of the analyses performed by Lazard Freres:

</TABLE>

   The Market Premium Analysis section was updated to include data on three
additional transactions. The resulting implied equity value range was $38.50 to
$41.50. In addition, the presentation once again noted the consideration
proposed to be paid to all holders of interests in the Partnership and PIMCO
Advisors, which included all cash amounts to be paid to unitholders and in
satisfaction of payments due under the 1994 Employment Termination Agreements.
Employing a hypothetical per unit price of $38 resulted in an aggregate implied
consideration of $4.6 billion. The presentation also stated the effect of
combining that aggregate unit based consideration with all proposed amounts to
be paid as retention and incentive amounts to management and amounts
contributed to the Pacific Investment Management Company bonus pool. This
aggregation of purchase price and other payments resulted in an equivalent per
unit amount of $42.66, for an aggregate consideration of $5.1 billion.

   Fixed Income Assets of the Allianz Group. The presentation included a
discussion of the fixed income assets under management of the Allianz group,
including insurance assets, that were proposed to be managed by Pacific
Investment Management Company following the merger and the subsequent
transactions. The analysis concluded by setting forth a projection of the
increase in total income to Pacific Investment Management Company that might
occur as a result of its management of the Allianz group assets. As a result of
the management of these additional assets, it was estimated that the total
income of Pacific Investment Management Company might increase within the range
of $21.7 million to $26.8 million for the year 2000 and within the range of
$41.3 million to $51.8 million for the year 2002.

October 29, 1999 Presentation

   On October 29, 1999, at the meeting which Partners LLC convened to consider
Allianz AG's offer, representatives of Lazard Freres made a presentation
outlining the key provisions of the proposed transaction. The presentation also
discussed the anticipated contribution of the Allianz group's fixed income
assets to Pacific Investment Management Company.

   Proposed Transaction Overview. The presentation discussed the terms of the
merger agreement and the subsequent transactions. For a more detailed
discussion of the structure and terms of the merger and the subsequent
transactions, see "The Transaction."

   Fixed Income Assets of the Allianz Group. The presentation concluded with a
discussion of the fixed income assets under management of the Allianz group,
including insurance assets, that will be managed by Pacific Investment
Management Company following the merger and the subsequent transactions. The
analysis concluded by setting forth a projection of the increase in total
income to Pacific Investment Management Company that might occur as a result of
its management of the Allianz group assets. As a result of the management of
these additional assets, it was estimated that the total income of Pacific
Investment Management Company would increase within the range of $21.9 million
to $27.1 million for the year 2000 and within the range of $41.3 million to
$51.8 million for the year 2002.

Opinion of Financial Advisor to Pacific Life

   Pacific Life, the direct parent corporation of PAM, retained Goldman Sachs
to act as its financial advisor in connection with the proposed transactions
and to evaluate the fairness, from a financial point of view, of the
consideration to be received by Pacific Life pursuant to the merger agreement
and the Continuing Investment Agreement between Allianz of America and PAM (the
"investment agreement"). On October 29, 1999, Goldman Sachs delivered its oral
opinion to Pacific Life's
board of directors that as of the date of such opinion, the consideration (with
the assumptions as described below) to be received by Pacific Life under the
merger agreement and the investment agreement was fair from a financial point
of view to Pacific Life. The opinion was confirmed by delivery of a written
opinion dated October 31, 1999.

   The full text of the written opinion of Goldman Sachs dated October 31,
1999, which sets forth assumptions made, matters considered and limitations on
the review undertaken in connection with their opinion, has been filed with the
Commission as Exhibit 99(b)(9) to the Schedule 13E-3 of PAM, Pacific Life,
PHLLC, Partners LLC, Partners GP and the Partnership filed in connection with
this proxy statement and is incorporated herein by reference.

   In connection with its opinion, Goldman Sachs reviewed, among other things:

  .  the merger agreement and the investment agreement;

  .  the Amended and Restated Agreement of Limited Partnership of PIMCO
     Advisors dated June 30, 1999;

  .  the Amended and Restated Agreement of Limited Partnership of the
     Partnership dated June 30, 1999;

  .  the annual reports on Form 10-K of the Partnership;

  .  the quarterly reports on Form 10-Q and other interim reports of the
     Partnership;

  .  the annual reports to shareholders of Pacific Life for the five years
     ended December 31, 1998 and quarterly reports of Pacific Life;

  .  audited GAAP financial statements of Pacific Life, PIMCO Advisors and
     the Partnership for the five years ended December 31, 1998;

  .  statutory annual statements filed by Pacific Life with the Insurance
     Department of the State of California for the five years ended December
     31, 1998;

  .  internal financial analyses and forecasts for Pacific Life prepared by
     the management of Pacific Life; and

  .  internal financial analyses and forecasts for PIMCO Advisors prepared by
     the management of PIMCO Advisors.

   Goldman Sachs also held discussions with members of the senior management of
Pacific Life, PIMCO Advisors, Allianz AG and Allianz of America regarding the
exchange of Advisors Class A Units beneficially owned by PAM for beneficial
ownership of Advisors Class E Units, including the put/call arrangement (the
"Exchange") and the other transactions contemplated by the merger agreement and
the investment agreement. In addition, they discussed PIMCO Advisors' past and
current business operations, financial condition and future prospects. Goldman
Sachs reviewed the reported price and trading activity for the Advisors Class A
Units, compared financial and stock market information for PIMCO Advisors with
similar information for other companies the securities of which are publicly
traded, reviewed the financial terms of recent business combinations in the
asset management industry specifically and in other industries generally, and
performed other studies and analyses as it considered appropriate.

                                       58
<PAGE>

   Goldman Sachs relied upon and assumed the accuracy and completeness of all
of the financial and other information reviewed by it for purposes of rendering
its opinion. The management of PIMCO Advisors informed Goldman Sachs that PIMCO
Advisors had not prepared formal forecasts beyond the current fiscal year.
Goldman Sachs noted that its review with respect to these forecasts, with the
consent of Pacific Life, was based on estimates for PIMCO Advisors published by
the Institutional Brokers Estimate System. In addition, Goldman Sachs did not
make an independent evaluation or appraisal of the assets or liabilities of
PIMCO Advisors or any of its subsidiaries and was not furnished with any such
evaluation or appraisal. Goldman Sachs had not been requested to evaluate, and
it expressed no opinion as to, the tax implications to Pacific Life of the
Exchange or the transactions contemplated by the Exchange. Goldman Sachs also
had not been requested to evaluate, and it expressed no opinion as to, the cash
or other distributions that may be made to Pacific Life as a holder of Advisors
Class E Units. With the consent of Pacific Life, Goldman Sachs evaluated the
consideration to be received by Pacific Life pursuant to the Exchange and
related transactions assuming Pacific Life had fully exercised on the date of
its opinion its put option with respect to its Advisors Class E Units as
contemplated by the put/call arrangement and received upon such exercise the
cash consideration being paid for the Advisors Class A Units for all of its
Advisors Class E Units. Although Goldman Sachs evaluated the consideration from
a financial point of view, it was not asked to and did not recommend the
specific consideration payable in the merger, the Exchange or the related
transactions. No other instructions or limitations were imposed by Pacific Life
on Goldman Sachs with respect to the investigations made or procedures it
followed in rendering its opinion.

   Goldman Sachs' advisory services and the opinion were provided for the
information and assistance of Pacific Life's board of directors in connection
with its consideration of the transaction contemplated by the merger agreement
and the investment agreement and do not constitute a recommendation to any
holder of Partnership units or Advisors Class A Units as to how such holder
should vote on any matters related to the merger or the related transactions.

   The following is a summary of the material financial analyses used by
Goldman Sachs in connection with providing its October 31, 1999 written opinion
to Pacific Life's board of directors. The summaries of financial analyses
include information presented in tabular format. In order to more fully
understand the financial analyses used by Goldman Sachs, the tables must be
read together with the full text of each summary. The tables alone do not
constitute a complete description of Goldman Sachs' financial analyses.

   (1) Premiums Analysis. Goldman Sachs analyzed the premiums implied for PIMCO
Advisors in the Exchange assuming Advisors Class A Unit prices of $38.00 and
$39.00 based on the trading price of the Advisors Class A Units on October 28,
1999, the date which was two trading days prior to the signing of the merger
agreement, July 6, 1999, the trading day prior to the date on which the press
first reported discussions between PIMCO Advisors and Allianz AG, and based on
an adjusted undisturbed price which is the estimated trading price for the
Advisors Class A Units adjusted for changes in the market value of publicly
traded master limited partnership stocks of asset managers between July 6, 1999
and October 28, 1999. Goldman Sachs then compared these results to the premiums
paid in selected financial services transactions having transaction values
greater than $1.0 billion since 1998. Goldman Sachs calculated the low, median
and high premiums in these financial services transactions based on the trading
market prices of the acquired companies four weeks prior to the announcement of
these transactions.

                                       59

   Goldman Sachs compared, among other things, the multiples for latest 12
months (through September 30, 1999) revenue, earnings before interests, taxes,
depreciation and amortization ("EBITDA"), and net income implied for PIMCO
Advisors by the Exchange assuming Advisors Class A Unit prices of $38.00 and
$39.00 against corresponding multiples, to the extent available, derived from
the selected transactions based on the purchase prices paid in these
transactions. Goldman Sachs also compared the percentage of assets under
management ("AUM") as of September 30, 1999 against corresponding percentages
derived from the selected transactions.

   The results of these analyses are summarized as follows:

multiples derived from the selected companies. EPS estimates for calendar year
1999 of $1.50 and $1.68 were based on estimates of the management of PIMCO
Advisors and Institutional Brokers Estimate System ("IBES"), respectively, and
EPS estimates for calendar year 2000 of $2.03 were based on estimates of IBES.

   The results of these analyses are summarized as follows:

   The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary described above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs' opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable
to PIMCO Advisors or Allianz of America or the contemplated transaction.

   The analyses were prepared solely for purpose of Goldman Sachs' providing
its opinion to Pacific Life's board of directors as to the fairness from a
financial point of view of the consideration (including the assumptions as
described above) to Pacific Life and do not purport to be appraisals or
necessarily reflect the prices at which businesses or securities actually may
be sold. Analyses based upon forecasts of future results are not necessarily
indicative of actual future results, which may be significantly more or less
favorable than suggested by such analyses. Because such analyses are inherently
subject to uncertainty, being based upon numerous factors or events beyond the
control of the parties or their respective advisors, none of Pacific Life,
PIMCO Advisors, Allianz AG, Allianz of America, Goldman Sachs or any other
person assumes responsibility if future results are materially different from
those forecast.

   As described above, Goldman Sachs' opinion to Pacific Life's board of
directors was one of many factors taken into consideration by Pacific Life's
board of directors in making its determination to approve the merger agreement
and the investment agreement. This summary does not purport to be a complete
description of the analysis performed by Goldman Sachs and is qualified by
reference to the written opinion of Goldman Sachs attached as an exhibit to the
Schedule 13E-3 of PAM. A copy of the presentation delivered by Goldman Sachs
has been filed as Exhibit 99(b)(8) to the Schedule 13E-3 filed by PAM with the
Commission and is available for inspection and copying at the principal
executive offices of Pacific Life during its regular business hours by any
holder of Partnership Units or any of its representatives who has been so
designated in writing upon written request and at the expense of the requesting
party.

   Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. Goldman Sachs is
familiar with Pacific Life, having provided investment banking services to
Pacific Life from time to time, including having acted as its financial advisor
in connection with its reorganization in September 1997 to a

                                       62
<PAGE>

mutual holding company structure and having acted as its financial advisor in
connection with, and having participated in certain of the negotiations leading
to, the merger agreement and the investment agreement. Goldman Sachs has also
provided investment banking services to PIMCO Advisors from time to time. In
addition, Goldman Sachs has provided investment banking services to Allianz AG
from time to time, including having acted as its financial adviser in
connection with the sale of its subsidiary San Francisco Re in November 1996,
as its financial advisor in connection with its acquisition of AGF in May 1998
and as a co-manager for three of its debt issuances from 1996 to 1998. Also, in
September 1999, Paul Achleitner, a managing director of Goldman Sachs, was
named chief financial officer of Allianz AG effective January 1, 2000.

   Goldman Sachs provides a full range of financial advisory and securities
services and, in the course of its normal trading activities, may from time to
time effect transactions and hold securities, including derivative securities,
of Pacific Life, PIMCO Advisors and Allianz AG for its own account and for the
accounts of customers. In addition, Goldman Sachs may provide investment
banking services in the future to PIMCO Advisors and Allianz AG.

   Pursuant to a letter agreement amendment dated August 25, 1999, Pacific Life
engaged Goldman Sachs to act as its financial advisor in connection with, among
other things, a potential sale of its minority interest in PIMCO Advisors.
Pursuant to the terms of the letter agreement, Pacific Life has agreed to pay
Goldman Sachs a retainer fee of $1.0 million, an advisory fee of $500,000
payable upon rendering the opinion to Pacific Life described in this proxy
statement, and a transaction fee of 0.30% of the net present value of the
aggregate consideration (as described in the letter agreement amendment),
subject to a maximum amount of $6.0 million, payable upon the exercise of the
put and call arrangements in the Exchange, less the advisory fee. Pacific Life
has agreed to reimburse Goldman Sachs for its reasonable out-of-pocket
expenses, including reasonable attorney's fees and expenses, and to indemnify
Goldman Sachs against certain liabilities, including certain liabilities under
the federal securities laws.

   Pacific Life does not currently intend to request an updated opinion from
Goldman Sachs. If a significant event regarding the merger or Exchange occurs,
such as a material amendment to the merger agreement or investment agreement
modifying the consideration provided for in the merger or Exchange, the Pacific
Life board of directors would consult with management and its legal and
financial advisors and take into account, consistent with its fiduciary duties,
all relevant facts and circumstances existing at that time, including general
market, economic and business conditions.

Management Compensation Consultants

   An important aspect of our discussions with Allianz AG was ensuring the
retention, after the Closing, of the key executives at Pacific Investment
Management Company, our premier fixed income manager. Accordingly, as part of
our evaluation of the proposed transaction with Allianz of America, we retained
McLagan Partners, Inc. to analyze and opine upon the reasonableness of the
payments proposed to be made under the PIMCO Advisors L.P. Retention Plan for
Executives of Pacific Investment Management Company (the "PIMCO Retention
Plan") being provided to the executives of Pacific Investment Management
Company in the proposed transaction. We selected McLagan Partners because of
their knowledge of our business and their expertise and reputation as
management consultants in the financial services industry. McLagan Partners is
an internationally recognized management consulting firm providing compensation
consulting and customized performance and compensation reports to the world's
leading financial services organizations. Their compensation related services
include annual and long-term incentive plan design, retention plan design and
evaluation in the context of mergers and acquisitions and surveys of pay
levels. McLagan Partners received $50,000, plus reimbursement of expenses, as
consideration for its services.

                                       63
<PAGE>

   In developing their opinion regarding the retention arrangements, McLagan
Partners reviewed the proposed form of PIMCO Retention Plan, and considered,
among other things:

  .  Competitive market practices associated with acquisition-related
     incentive programs.

  .  Pacific Investment Management Company's historical compensation
     practices and expected current year compensation levels.

   McLagan Partners also engaged in discussions with management of the
Partnership, including the director of human resources, and reviewed a summary
of the overall terms of the proposed transaction and the proposed form of
employment contracts for the managing directors of Pacific Investment
Management Company. Their analysis of external market practices included
observations regarding the level of retention payments, which tends to increase
in acquisitions driven by strategic business concerns, the timing of payments,
generally coinciding with a perceived period necessary for integration of the
acquired firm, individual award levels, which generally coincide with the
ability to impact future business results, and award levels as a multiple of
annual cash compensation.

   The opinion assumed the following:

  .  The loss of Pacific Investment Management Company executives and senior
     investment talent would have a materially adverse impact on PIMCO
     Advisors' total enterprise value.

  .  The retention incentive arrangements are not intended as substitutes for
     ongoing base salary and bonus compensation.

  .  The primary objective of the retention incentive arrangements is to
     retain and motivate key executives and investment talent subsequent to
     the transaction.

  .  A five year retention period is required to integrate the Pacific
     Investment Management Company business practices and processes, and the
     collective knowledge and expertise of its staff, into the Allianz group.

   Based on its analysis and assumptions, McLagan Partners opined that the
proposed retention incentive arrangements for Pacific Investment Management
Company under the PIMCO Retention Plan are reasonable in light of competitive
market practices and, moreover, existing compensation practices and levels at
Pacific Investment Management Company. Further, McLagan Partners opined that
those retention incentive arrangements are suitable to the Allianz group's
presumed objectives of retaining and motivating the officers of Pacific
Investment Management Company in the context of the contemplated acquisition.

           Financial Interests of Certain Persons in the Transaction

   The merger that you are being asked to approve is one of several
transactions contemplated by the merger agreement. These transactions taken
together create interests in several entities and persons that are different
from and in addition to your interests as a unitholder of the Partnership. You
should be aware of these other entities and persons and their interests in the
merger transactions that are different from yours.

The Partnership

   The executive officers and members of the Management Board of the
Partnership have conflicts of interest in the proposed transactions which
include:

  .  vesting and cash out of unit option awards and vesting of certain
     subaccounts under the Partnership's Deferred Compensation Plan;

  .  employment agreements;

  .  retention and severance payments; and

  .  indemnification and insurance.

In considering the fairness of the merger to the unitholders of the
Partnership, the general partner of the Partnership took into account these
interests. These interests are summarized below. None of the executive officers
or members of the Management Board of the Partnership are employees
or affiliates of Partners GP or its general partners, PHLLC and Partners LLC,
other than Ernest L. Schmider who was admitted as a member of Partners LLC
effective as of January 1, 2000.

   The following chart summarizes various employment related payments to each
of the executive officers and members of the Management Board in connection
with the proposed transactions.

(1) The retention payments to officers other than Mr. Cvengros are contingent
    on continued employment.
(2) Mr. Cvengros has announced his intention to resign at the end of the first
    quarter of 2000.
(3) The total payments listed herein do not include the executive's annual
    salary and are contingent upon continued employment.

   Unit Option Awards. As of the Closing, all outstanding unit options under
the 1998 Unit Incentive Plan, whether exercisable or not, will be cancelled and
terminated and will represent the right to receive a cash payment equal to the
excess of the Unit Price over the exercise price per unit of such unit option,
multiplied by the number of units subject to such unit option, together with
interest on such amount at 8% per annum from the Closing through the date such
payment is made. It is anticipated that such payment will be made approximately
100 days following the Closing.

   Deferred Unit Awards. Deferred unit awards under the 1998 Unit Incentive
Plan will, after the Closing, reflect the right to receive cash equal to the
Unit Price, multiplied by the number of units underlying such award, plus
interest at 8% per annum from the Closing through the vesting date of such
awards. Deferred unit awards will continue to vest according to their existing
vesting schedules.

   Deferred Compensation Plan. The Advisors Class A Units held in the trust
under the Deferred Compensation Plan (other than those related to deferred
restricted unit awards) will be exchanged by

                                       65
<PAGE>

the plan's trustee for cash in an amount per unit equal to the Unit Price.
Under the terms of the plan, any unvested account balances reflecting discount
investment or reinvestment of deferred compensation will vest. Each Advisors
Class A Unit representing an unvested deferred restricted unit held in the
trust generally will not vest, and will be exchanged by the plan trustee for a
note from Allianz of America with a principal balance equal to the Unit Price
multiplied by the number of unvested units. The note will bear interest at 8%
per annum, will be payable as and when the units vest on the original vesting
schedule and will be guaranteed by Allianz AG. Following the Closing, it is
expected that plan participants' account balances will be measured by, and the
assets held by the plan's trustee will be invested in, such investments as may
be individually directed by each participant.

   Most of the executive officers will benefit from the transaction in that the
unvested portions of account balances reflecting discount investment or
reinvestment of deferred compensation will vest at Closing. In addition, all of
the deferred restricted units held in the plan account for the benefit of
Mr. Treadway will vest and therefore be exchanged with all other vested units
in the plan for cash equal to the Unit Price. While these unvested plan
balances will vest at the Closing, all amounts deferred must remain in the
trust through the end of the scheduled deferral period.

   Employment Agreements. The merger agreement provides that in connection with
the Closing, PIMCO Advisors will enter into employment agreements with Robert
M. Fitzgerald, Kenneth M. Poovey, Stephen J. Treadway, James G. Ward and
Richard M. Weil. The initial term of each executive's employment agreement will
be two years, beginning January 1, 2000, with automatic renewal in the absence
of notice from PIMCO Advisors or the executive six months prior to the
expiration of the term, for successive one year periods. The annual salary
under the employment agreements for each of Messrs. Fitzgerald, Poovey,
Treadway, Ward and Weil will be $250,000, $400,000, $350,000, $200,000 and
$275,000, respectively. In addition, each of the executives will receive annual
performance based bonuses, retention payments (as described below) and be
entitled to participate in the benefit plans and programs of PIMCO Advisors
that are open to employees in similar positions. Mr. Poovey's agreement
provides for a minimum annual performance-based bonus of $1.5 million for each
year of the initial two year term of the agreement. In addition, Mr. Poovey's
employment agreement reflects his right to use an apartment in New York City as
well as his right to purchase the apartment both of which rights predate the
merger agreement.

   If an executive's employment is terminated for any reason other than for
cause by PIMCO Advisors or voluntarily by the executive, all amounts payable
under the employment agreement, including, but not limited to the salary and
retention payments will immediately become payable as if he continued to be
employed through the term of the employment agreement, the executive will
continue to receive performance bonuses on such dates as if the executive had
continued to be employed through the term of the employment agreement, but in
amounts which are tied to the previous year's performance bonus (and not to the
current year's results), the executive's awards under the 1998 Unit Incentive
Plan will immediately vest, and PIMCO Advisors will continue to provide all of
the benefits set forth in the employment agreement through the end of the
current term of the employment agreement in effect as of the date of
termination.

   Retention and Severance Payments. In connection with the transactions
contemplated by the merger agreement, PIMCO Advisors will adopt the PIMCO
Advisors L.P. Transition and Retention Plan. The plan provides for transition
payments for departing employees and retention awards payable over two to five
years contingent on continued employment to key employees remaining with the
business. In addition, the plan provides for incentive awards for employees in
the retail and equity groups which vest over five years based on achievement of
performance goals. Mr. Cvengros,

                                       66
<PAGE>

who has elected not to continue his employment with PIMCO Advisors following
the Closing, will receive a transition award of $1.667 million in each of the
three years following the Closing. Mr. Poovey will receive a retention award of
$5 million per year for two years conditioned on continued employment, and
Messrs. Weil, Fitzgerald and Ward will receive retention awards of $500,000,
$300,000 and $240,000, respectively, per year for five years conditioned on
continued employment. Mr. Treadway will receive a retention award of $1 million
per year for five years conditioned on continued employment and be eligible for
an additional award of up to $1 million per year for five years upon the
satisfaction of certain performance goals by PIMCO Advisors' retail business.
In addition, Mr. Schmider will receive a retention award under the retention
plan for executives of Pacific Investment Management Company (described under
"--Partners GP--Partners LLC" below) of $600,000 per year for five years
conditioned on continued employment.

   Indemnification and Insurance. Pursuant to the merger agreement, Allianz of
America has, for a period of six years from the Closing, agreed that it will:

  .  not, and cause each of its subsidiaries not to, amend or modify any
     provision of any partnership agreement, limited liability company
     agreement or indemnification agreement pursuant to which any of the
     Partnership, PIMCO Advisors, PAM, Partners GP, Partners LLC or PHLLC or
     to which any officer, director, member, partner or other controlling
     person of such entities is or may be entitled to exculpation or
     indemnification, and Allianz of America will cause PIMCO Advisors to
     honor any such provision and to pay to the intended recipient any
     amounts to which such person is properly entitled under such provisions;
     and

  .  not take any action which causes the termination or cancellation of any
     extension of directors' and officers' liability insurance for partners,
     members, managing members, directors and officers of the Partnership,
     PIMCO Advisors, Partners LLC, PHLLC, PAM and Partners GP, unless such
     insurance is replaced.

   PIMCO Advisors will purchase an extension of its current directors' and
officers' liability insurance coverage for a premium of not more than $150,000
per year.

Partners GP

   Partners GP is a general partnership with two partners, PHLLC and Partners
LLC. PHLLC is a subsidiary of PAM. Partners LLC is the managing partner of
Partners GP, and is owned and managed by the current and former managing
directors of Pacific Investment Management Company. You should be aware of
their respective interests.

Partners LLC

   Partners LLC is the managing partner of Partners GP. Partners LLC owns
142,480 Advisors Class A Units, which will be purchased by Allianz GP Sub at
the same Unit Price as you receive. PHLLC will also sell its general partner
interest to Allianz GP Sub for nominal consideration of $100.

   The members of Partners LLC are all of the current and certain former
managing directors of Pacific Investment Management Company. The members of
Partners LLC are William R. Benz, Robert W. Burns, Christopher P. Dialynas,
Mohammed A. El-Erian, William H. Gross, John L. Hague, Pasi M. Hammalainen,
Brent R. Harris, Brent L. Holden, Margaret E. Isberg, John S. Loftus, Dean S.
Meiling, James F. Muzzy, William F. Podlich III, William C. Powers, Ernest L.
Schmider,

                                       67
<PAGE>

Lee R. Thomas, William S. Thompson Jr., and Benjamin L. Trosky (each of the
foregoing, the "PIMCO Managing Directors") as well as David Edington and Frank
Rabinovitch, who are former managing directors. As members of Partners LLC,
these persons will receive benefits in the merger transactions different from
your interests as unitholders of the Partnership. These include:

  .  new employment and consulting agreements for the PIMCO Managing
     Directors;

  .  restricted stock awards for certain PIMCO Managing Directors;

  .  eligibility of PIMCO Managing Directors to participate in the PIMCO
     Profit Sharing Plan, Class B Unit Purchase Plan and PIMCO Retention
     Plan;

  .  amendment and satisfaction of certain 1994 Employment Termination
     Agreements;

  .  benefits associated with the Pacific Investment Management Company
     restructuring;

  .  vesting and cash out of unit option awards and vesting of certain
     subaccounts under the Partnership's Deferred Compensation Plan for the
     PIMCO Managing Directors; and

  .  indemnification and insurance.

   Certain members of Partners LLC will receive employment-related
compensation, in the aggregate, of up to $442.5 million in cash payments and up
to 182,488 shares of Allianz AG stock with an assumed value of $50.0 million,
over a five year period contingent on continued employment, as well as
aggregate closing payments of approximately $603.3 million in cash and
approximately 364,977 shares of Allianz AG stock with an assumed value of
$100.0 million in settlement of pre-existing unit-based entitlements (the 1994
Employment Termination Agreements and outstanding unit options) as a result of
the transactions. In addition, such persons will have the opportunity to
participate in the other employee benefits programs described below. Of such
amounts, in connection with the closing, Mr. Thompson, the Chief Executive
Officer of Pacific Investment Management Company, will receive payments in cash
and Allianz AG stock with a potential assumed aggregate value of $103.5
million, of which $48.5 million will be received at the closing in satisfaction
of pre-existing unit based entitlements and up to $55.0 million of which will
be received over a five year period conditioned on continued employment. In
connection with the closing, Mr. Gross, the Chief Investment Officer of Pacific
Investment Management Company, will receive payments in cash and Allianz AG
stock with a potential assumed aggregate value of $462.4 million, of which
$263.4 million will be received at the closing in satisfaction of pre-existing
unit based entitlements and up to $199.0 million of which will be received over
a five-year period conditioned on continued employment. The value of payments
to each of the members of Partners LLC described above assumes a Unit Price of
$38.75 and a value of $273.99 per share of Allianz AG stock, the average
trading price for such stock for the 30 days prior to the date of public
announcement of discussions between Allianz AG and PIMCO Advisors. As of March
2, 2000, the closing price of the Allianz AG stock was $346.94 per share,
increasing the stock component of employment related compensation to be
received by the members of Partners LLC to $63.3 million, all of which will be
received by Messrs. Thompson and Gross, and increasing the stock component of
the closing payments in settlement of pre-existing unit-based entitlements to
be received by the members of Partners LLC to $126.6 million, of which Messrs.
Thompson and Gross will receive $10.8 million and $63.7 million, respectively.

   In considering the fairness of the merger to the unitholders of the
Partnership, the members and management board of Partners LLC took into account
these additional interests which are

                                       68
<PAGE>

summarized below. Such considerations took into account the fact that benefits
being received pursuant to the amended Profit Sharing Plan and the consequent
adoption of the Class B Unit Purchase Plan resulted from the desire of Allianz
AG to restructure or modify pre-existing contractual arrangements, and that the
benefits under the 1994 Employment Termination Agreements, the Unit Options and
the Deferred Compensation Plan resulted from the desire of Allianz AG to
settle, at the same per unit price being paid to the public, those pre-existing
contractual arrangements. Further, they took note of the fact that retention
payments are customary in transactions involving the acquisition of investment
advisors in order to retain and motivate key investment managers, and that the
retention payments proposed by Allianz AG were found to be reasonable by
McLagan Partners in its opinion.

   Employment and Consulting Agreements. In connection with the transactions
under the merger agreement, each of the PIMCO Managing Directors is expected to
enter into a new employment or consulting agreement with Pacific Investment
Management Company. The general terms of these agreements are set forth below.

   The initial term of the employment agreements will be five years from the
Closing (seven years for Messrs. Gross and Thompson). Each managing director
will receive an annual salary, and will be entitled to participate in the
Pacific Investment Management Company Non-Qualified Profit Sharing Plan (the
"PIMCO Profit Sharing Plan"), the Pacific Investment Management Company Class B
Unit Purchase Plan (the "Class B Unit Purchase Plan"), and the PIMCO Advisors
L.P. Retention Plan for Executives of Pacific Investment Management Company
(the "PIMCO Retention Plan"). Additionally, the contracts provide for
participation in health, welfare, insurance, pension and other benefit plans
and programs.

   If the managing director voluntarily terminates his or her employment, if
his or her employment is terminated for cause, or if the Executive Committee of
Pacific Investment Management Company terminates his or her employment, then
all obligations of Pacific Investment Management Company under the related
employment agreement will terminate. The agreement allows the Executive
Committee of Pacific Investment Management Company to terminate a managing
director, with or without cause, by the affirmative vote of four of its five
members.

   If an employment agreement is terminated for any other reason, the relevant
managing director will have the right to continue to be paid his or her base
salary for one year from the date of termination or the then scheduled
termination date of the agreement, whichever is earlier; the managing director
will continue to receive all amounts payable under the PIMCO Profit Sharing
Plan and the PIMCO Retention Plan, as if the managing director had remained
employed through the termination date; in the case of Messrs. Thompson and
Gross, all shares of restricted stock that would have vested as a result of
their continued employment will immediately vest; and all units purchased by
the managing director under the Class B Unit Purchase Plan will (i) in the
event of death or incapacity of the managing director, be repurchased by PIMCO
Advisors in accordance with the terms of the plan and (ii) in the event of an
involuntary termination other than for cause or by the Executive Committee of
Pacific Investment Management Company, upon payment of any outstanding amounts
due under the purchase note, become released units owned by the terminated
managing director and subject to repurchase by PIMCO Advisors upon the exercise
of the terminated managing director's put right in accordance with the terms of
the plan. Additionally, in the event of an involuntary termination or
termination by death, the reduction provisions of the PIMCO Retention Plan
shall cease to be applicable.

                                       69

   In addition, the employment agreements of each of Messrs. Thompson and Gross
provide for a grant of restricted stock of Allianz AG (described below), and
provide that if such managing director's employment terminates other than for
cause, by affirmative vote of the Executive Committee of Pacific Investment
Management Company, by death or incapacity, or voluntarily, then:

  .  his participation percentage in the PIMCO Profit Sharing Plan will be
     fixed at a specified percentage and he will continue to participate in
     the PIMCO Profit Sharing Plan according to that percentage through the
     expiration of the term of the employment agreement; and

  .  he will be entitled to all benefits accrued under the restricted stock
     agreement and all awards to be made under the agreement, both fixed and
     discretionary, will vest immediately.

   In recognition of their anticipated contribution to both Pacific Investment
Management Company and Allianz of America, Messrs. Gross and Thompson will be
awarded restricted stock of Allianz AG in connection with the transactions. On
each of the first five anniversaries of the closing date, 9,124 shares of
Allianz AG stock (worth approximately $2.5 million at $273.99 per share, the
average of 30 day trading price prior to October 4, 1999, the date of public
announcement of discussions between PIMCO Advisors and Allianz AG) will vest
for each of Messrs. Thompson and Gross. On each such date, each of Messrs.
Gross and Thompson also will be eligible for vesting of up to 9,124 additional
shares of Allianz AG stock to be awarded at the discretion of the Chief
Executive Officer of the Allianz Asset Management division of Allianz group.

   Two of the PIMCO Managing Directors, Messrs. Meiling and Podlich, will enter
into five year consulting agreements with Pacific Investment Management
Company. Each consultant will receive an annual consulting fee and will be
entitled to participate in the PIMCO Retention Plan. Messrs. Meiling and
Podlich will be entitled to receive, subject to the satisfaction of certain
conditions, up to an aggregate of $43.6 million over a five year period
pursuant to the consulting arrangements and the PIMCO Retention Plan.
Additionally, the consulting agreements provide for participation in health,
welfare, insurance, pension and other benefit plans and programs.

   If the consultant voluntarily terminates his consulting arrangement or if
his consulting arrangement is terminated for cause, then all obligations of
Pacific Investment Management Company under the consulting agreement will
terminate. If the agreement is terminated for any other reason, the consultant
will have the right to continue to be paid his base consulting fee for one year
from the date of termination or the scheduled termination date of the
agreement, whichever is earlier, and the consultant will continue to receive
all amounts payable under the PIMCO Retention Plan, as if the consulting
arrangement had continued through the scheduled termination date.

   Reorganization of Pacific Investment Management Company; Profit Sharing
Plan. The PIMCO Managing Directors currently have the right to substantial
autonomy in the management of the business of Pacific Investment Management
Company, and also have the right to participate in the 1994 Non-Qualified
Profit Sharing Plan of Pacific Investment Management Company. Under the 1994
profit sharing plan, the PIMCO Managing Directors and other executive employees
share in a bonus pool equal to 45% of the adjusted net profit of Pacific
Investment Management Company. Both the management rights and the profit
sharing bonus pool are guaranteed to the PIMCO Managing Directors through the
organizational documents of Pacific Investment Management Company and their
existing employment agreements, and cannot be changed without a supermajority
vote of the PIMCO Managing Directors.

   Pursuant to the merger agreement, the PIMCO Managing Directors will agree to
a modification of these arrangements. First, the PIMCO Managing Directors will
agree to the reorganization of

                                       70
<PAGE>

Pacific Investment Management Company into a limited liability company, with
PIMCO Advisors as the managing member. The existing structural management
rights of the PIMCO Managing Directors will be replaced by a revocable
delegation by PIMCO Advisors to the PIMCO Managing Directors of management
rights similar to those they currently enjoy.

   While the delegation of authority is revocable at any time, Allianz of
America has agreed that if PIMCO Advisors revokes its delegation of authority
without making a good faith determination that internal circumstances exist at
Pacific Investment Management Company that are not being effectively addressed
by management and which, if continued, would likely result in a substantial
impairment to the value of Pacific Investment Management Company, then the
following will occur:

  .  all amounts payable to the PIMCO Managing Directors under the PIMCO
     Retention Plan will vest and be paid to the PIMCO Managing Directors as
     if they remained employed by Pacific Investment Management Company,
     whether or not they remain employed;

  .  provisions of the PIMCO Retention Plan requiring the forfeiture of
     retention payments in the event that Allianz of America suffers an
     indemnified loss under the merger agreement and the repayment of
     retention payments in the event that a PIMCO Managing Director violates
     his non-competition covenants will cease to be applicable;

  .  the covenants not to compete in the 1994 Employment Termination
     Agreements will terminate at the earlier of eighteen months from the
     date of revocation or at their scheduled termination date;

  .  all shares of restricted stock of Allianz AG awarded to Messrs. Thompson
     and Gross will vest, including those shares subject to discretionary
     vesting, and the restricted period for those shares will terminate;

  .  all put rights, call rights and rights of repurchase which are
     exercisable by PIMCO Advisors upon the termination of employment or
     disability of a participant under the Class B Unit Purchase Plan will be
     cancelled and terminated; and

  .  all other put rights, call rights and repurchase rights under the Class
     B Unit Purchase Plan will continue to be exercisable according to the
     terms, and at the times, set forth in the Class B Unit Purchase Plan,
     except that the call or put price will be the greater of such price
     calculated as if the right had been exercised at the time of the
     improper revocation of authority and such price calculated at the time
     the right is exercised.

   In addition, the PIMCO Managing Directors will agree to an amendment of the
1994 profit sharing plan in the form of a new plan, the PIMCO Profit Sharing
Plan, which will reduce over five years the profit sharing percentage from 45%
to 30% of adjusted net profit. Also, the PIMCO Profit Sharing Plan will be
amended to provide that the net profits from which the bonus pool is calculated
shall be deemed to include the net profit of certain other fixed income
investment advisors owned by Allianz AG and its affiliates. In addition, for
the first two years following the Closing, the profit sharing pool will be
guaranteed a minimum contribution of at least $10 million per year from the
management of insurance assets of affiliates of Allianz AG. Allianz AG has
guaranteed all of Allianz of America's obligations in this regard.

   Class B Unit Purchase Plan. In connection with the reduction in amounts
payable under the PIMCO Profit Sharing Plan, Pacific Investment Management
Company and PIMCO Advisors will adopt the Class B Unit Purchase Plan to allow
participants to purchase Class B Units in Pacific Investment Management Company
(the "PIMCO Class B Units") which, in the aggregate, will entitle the holders

                                       71
<PAGE>

to distributions equal to up to 15% of the adjusted net profit of Pacific
Investment Management Company (computed in accordance with the PIMCO Profit
Sharing Plan). One-fifth of the PIMCO Class B Units will be sold each year for
the five years during which the profit sharing pool is being reduced. Each of
the PIMCO Managing Directors will be eligible to participate in this plan. The
compensation committee of Pacific Investment Management Company will determine
which participants may purchase PIMCO Class B Units and the number of PIMCO
Class B Units that each participant may purchase.

   The PIMCO Class B Units will be purchased pursuant to full recourse notes
bearing interest at the rate of 7% per annum. The principal amount of the notes
will amortize as follows:

  .  for units purchased in the years 2000 and 2001, all of the note
     principal will be due in the fourth year after purchase;

  .  for units purchased in the year 2002, one-half of the note principal
     will be due in each of years 2005 and 2006; and

  .  for units purchased in 2003 and 2004, one-third of the note principal
     will be due in each of the second, third and fourth years after
     purchase.

The base compensation of each participant will be increased in an amount equal
to the principal amortization applicable to notes given by such participant to
purchase PIMCO Class B Units. PIMCO Class B Units purchased under the plan will
be held in escrow by PIMCO Advisors and will be released from escrow as
principal payments on the related note are made. The PIMCO Class B Units may
not be transferred without the consent of PIMCO Advisors.

   Each year, up to 20% of the PIMCO Class B Units purchased under the plan
will be subject to repurchase by PIMCO Advisors at the "Call Price," determined
by multiplying the PIMCO Class B Unit distribution amount for the previous
calendar year by a multiple, ranging from 5 to 14, based on Pacific Investment
Management Company's investment performance and revenue growth, and multiplying
that amount by 1.02.

   In addition, unless otherwise provided in a participant's employment
agreement, upon a termination of employment of a participant other than as a
result of death or disability, PIMCO Advisors will have the right to repurchase
a number of PIMCO Class B Units equal to the unpaid principal balance of the
related note divided by the original purchase price, and in each of the three
years following such termination, PIMCO Advisors will have the right to
repurchase some or all of such participant's remaining PIMCO Class B Units at
the Call Price. Finally, unless otherwise provided in a participant's
employment agreement, upon the death or disability of a participant, all vested
PIMCO Class B Units will be repurchased by PIMCO Advisors at a price equal to
the average of the Call Price and the Put Price (defined below) and any
unvested PIMCO Class B Units will be repurchased at the original purchase
price.

   Each Participant has a corresponding right to cause PIMCO Advisors to
purchase at the Put Price on March 31 of each year, up to 20% (on a cumulative
basis) of such participant's PIMCO Class B Units. In addition, in each of the
three years following a termination of employment each participant has the
right to cause PIMCO Advisors to purchase some or all of the participant's
PIMCO Class B Units. Amounts payable in connection with the put and call rights
under the Class B Unit Purchase Plan are subject to reduction in the event of
an indemnified loss by Allianz of America or its affiliates under the merger
agreement.

   The "Put Price" is determined by multiplying the PIMCO Class B Unit
distribution amount for the previous calendar year by a multiple, ranging from
6 to 12, based on Pacific Investment Management Company's investment
performance and revenue growth, and multiplying that amount by 1.02.

                                       72
<PAGE>

   PIMCO Retention Plan. The PIMCO Retention Plan will be adopted in connection
with the Closing to provide fixed and variable retention arrangements for each
of the PIMCO Managing Directors and other key employees of Pacific Investment
Management Company. Fixed retention awards will vest and be paid over a period
of three to five years. Variable retention awards will be based on performance
relative to established benchmarks. In connection with the Closing, each of the
PIMCO Managing Directors will be awarded fixed retention payments which are to
vest and be paid ratably over five years. The nineteen PIMCO Managing Directors
will in aggregate be awarded retention payment grants of $88.5 million per year
for each of the five years following the Closing, subject to continued
employment. The PIMCO Managing Directors will not be eligible for any variable
retention awards under the PIMCO Retention Plan. Amounts payable under the
PIMCO Retention Plan are subject to reduction in the event of an indemnified
loss by Allianz of America or its affiliates under the merger agreement. In
addition, the awards under the PIMCO Retention Plan provide that one-half of
all amounts paid to a participant must be repaid to PIMCO Advisors if the
participant violates non-competition obligations.

   Employment Termination Agreements. The 1994 Employment Termination
Agreements require PHLLC to pay eight current and two former managing directors
of Pacific Investment Management Company who are parties to those contracts
noncompete payments equal to distributions on, or sales proceeds of, an
aggregate of 17,402,107 Advisors Class A Units. In connection with the merger
agreement, the eight managing directors who are parties to such contracts and
who are still acting as managing directors of Pacific Investment Management
Company and one former managing director of Pacific Investment Management
Company have agreed to amend their 1994 Employment Termination Agreements. The
eight current managing directors who have agreed to amend their 1994 Employment
Termination Agreements are Messrs. Gross, Hague, Harris, Meiling, Muzzy,
Podlich, Powers and Thompson and the former managing director who has agreed to
amend his 1994 Employment Termination Agreement is Mr. Edington. Under the
amendments each of the current and former managing directors will receive at
Closing the ETA Payment, equal to the Unit Price multiplied by the number of
units which relate to his 1994 Employment Termination Agreement in satisfaction
of the noncompete payments payable under that agreement. The amendments will
provide that the noncompete arrangements in the 1994 Employment Termination
Agreements will, with some modifications, remain binding on the current and
former managing directors. Each amendment will provide:

  .  a covenant not to compete for five years from the Closing (or, for the
     former managing director, for the remainder of the term of his
     covenant);

  .  an agreement to repay the ETA Payment if the noncompete covenant is
     violated during the five-year period; and

  .  the cessation of any further noncompete payments under the 1994
     Employment Termination Agreement.

   Except as provided below, payments will be made in cash and stock of Allianz
AG. Each of Messrs. Meiling and Podlich, who are not full-time employees of
Pacific Investment Management Company, and Mr. Edington, who is a former
managing director, will receive his ETA Payment entirely in cash.

   The aggregate payment at the Closing to the eight current and one former
managing directors whose 1994 Employment Termination Agreements will be amended
will consist of $549.3 million in cash and 364,977 shares of stock in Allianz
AG. Based on 16,231,637 Advisors Class A Units, a Unit Price of $38.75 and an
assumed value of $273.99 per share of Allianz AG stock, the average

                                       73
<PAGE>

trading price for Allianz AG for the 30 days prior to public announcement of
discussions between Allianz AG and PIMCO Advisors, the payments will have an
aggregate value of $649.3 million. Because a portion of these payments is made
in stock of Allianz AG, the value of these payments will fluctuate based on the
price per share of that stock.

   Mr. Rabinovitch, a former managing director and party to a 1994 Employment
Termination Agreement has elected not to amend his 1994 Employment Termination
Agreement. Following the Closing, PHLLC, which will then be an indirect
subsidiary of Allianz of America, will continue to make noncompete payments to
him under his agreement. Following the acquisition of Partners GP described
above, Allianz of America will cause Partners GP to retain a number of Advisors
Class A Units equal to those on which payments are due under the remaining 1994
Employment Termination Agreement (1,170,470 units). In the Advisors Merger,
those units will be converted into new Advisors Class B Units. The new Advisors
Class B Units will have a liquidation preference equal to the Unit Price and
will be entitled to a distribution equal to 7.5% of the Unit Price per annum,
payable quarterly. Unless the Advisors Class B Units are redeemed on the terms
described below, through the period ending in November 2036, Allianz of America
will cause PHLLC to make noncompete payments based on the distributions from
those Advisors Class B Units. Commencing five years after the Closing, the
former managing director may request that any or all Advisors Class B Units on
which his employment termination payments are based be redeemed at the Unit
Price (plus accrued but unpaid distributions) by PIMCO Advisors, and commencing
ten years after the Closing, or earlier upon certain circumstances, PIMCO
Advisors may redeem the Advisors Class B Units at the Unit Price (plus accrued
but unpaid distributions) at its discretion. Upon any such redemption, the
redemption price will be paid to him in accordance with his 1994 Employment
Termination Agreement. In addition, he may elect to receive that cash
immediately upon the execution of an amendment similar to those described above
in which such managing directors agree to extend the duration of the non-
competition provisions.

   Unit Options and Deferred Compensation Plan. As described above under "--The
Partnership--Unit Option Awards" and "--Deferred Compensation Plan," as of the
Closing, holders of unit option awards and participants in the Deferred
Compensation Plan will benefit from the transactions. Unit option awards,
whether or not vested, will be converted into the right to receive cash
following the Closing equal to the excess of the Unit Price over the exercise
price of the option as of the Closing, together with interest on such amount at
8% per annum through the date such payment is made. Certain unvested
subaccounts in the Deferred Compensation Plan will vest and units in the trust
will be exchanged for cash at the Unit Price (or the right to receive cash upon
vesting of deferred restricted unit awards), which is expected to be invested
as directed by plan participants.

   As of December 31, 1999, the PIMCO Managing Directors hold unit option
awards for an aggregate of 2,478,000 Advisors Class A Units, at an average
exercise price of $16.92 per unit, which will result in payments of
approximately $54 million in the aggregate at the Closing, based on a Unit
Price of $38.75. Approximately 13.7% of these unit options (representing
approximately $7.4 million of such amount) will be unvested immediately prior
to Closing. In addition, the PIMCO Managing Directors participate in the
Deferred Compensation Plan. At the Closing, 268,793 Advisors Class A Units,
having a value of $10,415,729 based on a Unit Price of $38.75, attributable to
unvested subaccounts of the PIMCO Managing Directors under the Deferred
Compensation Plan will vest.

   Indemnification and Insurance. In addition, Partners LLC, Partners GP and
each executive officer, director, member, partner or other controlling person
of those entities will have the benefits of

                                       74
<PAGE>

the indemnification and insurance previously described under "--The
Partnership--Indemnification and Insurance."

PHLLC and PAM

   The sole member of PHLLC is PAM, a subsidiary of Pacific Life. PAM has
several interests in the transaction that are different from the interests of
the Partnership's unitholders. These interests include:

  .  PAM (PHLLC's parent company) will retain an interest in PIMCO Advisors
     subject to put and call rights which may result in a future sale of
     PAM's interest to Allianz of America; and

  .  indemnification and insurance.

In addition, PAM's ultimate parent corporation, PMHC, is having discussions
with Allianz AG regarding a possible acquisition of PMHC by Allianz AG. PAM
considered these interests, described below, when evaluating the fairness of
the merger and the other transactions contemplated by the merger agreement to
the unitholders of the Partnership.

   Pacific Life's indirect investment, through its subsidiaries, in PIMCO
Advisors represents an important part of its overall business. As one of the
two general partners of our general partner, Pacific Life's indirect subsidiary
PHLLC is involved in the management of PIMCO Advisors, and the continued
management involvement in PIMCO Advisors forms a part of Pacific Life's ongoing
business plan. This affiliation has enhanced Pacific Life's identity in certain
strategic financial services markets. The relationship between the entities has
proven and continues to prove useful in branding, marketing and selling a
number of Pacific Life products and services. Additionally, Pacific Life
utilizes the investment services of Pacific Investment Management Company and
other investment services of PIMCO Advisors. In this respect, PAM's ownership
interest in PIMCO Advisors differs from that of the investment interest
represented by the limited partner units. Although Pacific Life concluded that
the retention by PAM of a management interest in the general partner of PIMCO
Advisors was consistent with Pacific Life's business plan, Pacific Life
believes, based on the information described elsewhere in this proxy statement,
that the consideration offered to the other partners by Allianz of America is
fair to, and in the best interest of, the Partnership's unitholders.

   The identity and background of the current directors and executive officers
of PAM and its parent entities, PMHC, Pacific LifeCorp and Pacific Life, are
described under "Directors and Management."

   Continuing Investment in PIMCO Advisors. PAM beneficially owns 37,218,634
Advisors Class A Units which, unlike the units owned by other unitholders of
PIMCO Advisors and the Partnership, will not be sold for or converted into cash
along with the other interests in the Partnership and PIMCO Advisors.

   Through a series of transactions ending with the Advisors Merger, PAM,
through its subsidiary PacFin and its interest in PacPartners, will maintain
its investment in PIMCO Advisors in the form of 3,722 Advisors Class E Units
(this number may be reduced by two Class E Units to the extent that the
consents of certain partially owned limited partnership subsidiaries of PAM are
not obtained (in which case, Advisors Class A units held by the limited
partnership subsidiaries will convert to cash at the Unit Price in the Advisors
Merger along with all such other units in those partially owned

                                       75
<PAGE>

limited partnership subsidiaries)). The Advisors Class E Units will be entitled
to distributions which, on an annual basis, in the aggregate will equal:

  .  $1.05 per Advisors Class A Unit previously beneficially owned by PAM, a
     fixed return representing the historical returns from PIMCO Advisors'
     retail and equity asset management business; plus

  .  20% of the Adjusted OPAD of Pacific Investment Management Company.

   For these purposes, the Adjusted OPAD of Pacific Investment Management
Company will be calculated in accordance with the provisions of the Pacific
Investment Management Company Profit Sharing Plan in effect at the Closing,
before payment of profit sharing bonuses under that plan and without taking
into account:

  .  income attributable to performance fees which are subject to forfeiture;

  .  deductions for annual compensation paid to employees above $450,000,
     adjusted for inflation after the year 2000;

  .  deductions attributable to certain option and deferred compensation
     benefits; and

  .  severance and executive retention payments paid pursuant to the merger
     agreement.

   The calculation will also exclude the effect of:

  .  certain costs and revenues associated with the provision of management
     or subadvisory services with respect to certain assets; and

  .  the subsidy, if any, to the Pacific Investment Management Company bonus
     pool in 2000 through 2002.

   The distributions with respect to the Advisors Class E Units were designed
to limit PAM's return to one based on PIMCO Advisors' fixed income asset
management business, plus a fixed return representing the historical return
from PIMCO Advisors' retail and equity asset management business. Allianz AG
negotiated a fixed return for the retail and equity business so it would have
the flexibility it requires to restructure the PIMCO Advisors' retail and
equity asset management business and combine it with existing Allianz AG retail
and equity asset management businesses. Pursuant to the agreements between
Allianz AG and the Pacific Investment Management Company managing directors,
Allianz AG is committed to continue to permit the Pacific Investment Management
Company fixed income business to operate autonomously. More details on the
Pacific Investment Management Company Non-Qualified Profit Sharing Plan are
found in "--Partners GP--Partners LLC--Reorganization of Pacific Investment
Management Company; Profit Sharing Plan."

   The Advisors Class E Units will be subject to put and call options held by
PAM and Allianz of America, respectively. The put option held by PAM will allow
it to require Allianz of America, on the last business day of each calendar
quarter following the Closing, to purchase all of the Advisors Class E Units
owned directly or indirectly by PAM. The price at which Allianz of America must
purchase the Advisors Class E Units will be the Per Unit Value plus an amount
meant to approximate any accrued but unpaid distributions on the Advisors Class
E Units (the "Call Price"). The "Per Unit Value" means an amount per Advisors
Class E Unit equal to 14.0 multiplied by the sum of (A) $10,500, representing
$1.05 per Advisors Class A Unit beneficially owned by PAM prior to the
transaction, plus (B) 20% in aggregate of the Adjusted OPAD of Pacific
Investment Management Company for the most recently completed four calendar
quarters, computed to exclude certain performance fees, subject to adjustment

                                       76
<PAGE>


for certain losses of Allianz of America covered by the indemnification
provisions of the merger agreement, but in no event will the Per Unit Value be
an amount greater than $600,000 (or $60 per Advisors Class A Unit beneficially
owned by PAM prior to the transaction).

   The call option held by Allianz of America will allow it, on any April 30,
July 31, October 31 or January 31 beginning on January 31, 2003, to require
that PAM sell or cause to be sold to Allianz of America all of the Advisors
Class E Units owned directly or indirectly by PAM at the then prevailing Call
Price. Allianz of America may only exercise this call option if the Per Unit
Value of the Advisors Class E Units is at least $500,000 (or $50.00 per
Advisors Class A Unit beneficially owned by PAM prior to the transaction) at
the time. Additionally, Allianz of America will have a call option that will
become exercisable on the last business day of any calendar year in which a
change of control occurs for PMHC. The price per Advisors Class E Unit to
exercise this call option will be the greater of $387,500 (or $38.75 per
Advisors Class A Unit beneficially owned by the PAM prior to the transactions),
subject to downward adjustment if the Unit Price is adjusted downward, and the
then prevailing Call Price. Allianz AG has guaranteed, subject to certain
conditions, the obligations of PHLLC under the PacPartners limited liability
company agreement and of PacPartners under the PIMCO Advisors partnership
agreement.

   In connection with entering into the put and call arrangements, PAM will
agree that it and its subsidiaries will not compete with PIMCO Advisors'
business, without the consent of Allianz of America and subject to specified
exceptions.

   PAM initially will be the beneficial owner of 100% of the outstanding
Advisors Class E Units. A portion of the Advisors Class E Units will be held
through PAM's wholly-owned subsidiary, PacFin, and the remaining portion will
be held through PAM's ownership of the Class E Interests in PacPartners, which
will be the general partner of PIMCO Advisors following the Advisors Merger.
PacPartners initially will have two members: PHLLC, which will then be an
indirect wholly-owned subsidiary of Allianz of America, and PAM. PHLLC will be
the managing member of PacPartners and (generally) will have full authority and
control over all actions taken by PacPartners as the general partner of PIMCO
Advisors. However, the PacPartners limited liability company agreement and the
PIMCO Advisors partnership agreement will provide that PHLLC and PacPartners,
as the case may be, will not, without PAM's prior approval, be authorized to
cause PacPartners or PIMCO Advisors to take certain actions, including the
following:

  .  causing PacPartners to incur indebtedness that is recourse against PAM's
     Advisors Class E Units or the distributions on the Advisors Class E
     Units;

  .  terminating PacPartner's status as a general partner of PIMCO Advisors;

  .  generally taking any actions related to the nonrecourse indebtedness
     contributed by PAM to PacPartners;

  .  prior to December 6, 2001, causing PacPartners to sell or otherwise
     dispose of more than 50% of the Advisors Class A Units held by
     PacPartners;

  .  amending certain provisions of the PIMCO Advisors partnership agreement
     which could adversely affect the distributions with respect to Advisors
     Class E Units;

  .  causing a sale or other disposition of all or substantially all of the
     assets of Pacific Investment Management Company or all or substantially
     all of PIMCO Advisors' interests in Pacific Investment Management
     Company;

  .  effecting certain mergers of PIMCO Advisors with other business
     entities; and

  .  causing any action which would make it impossible to carry on the
     ordinary business of Pacific Investment Management Company.

   In addition, in consideration of PAM agreeing to give up certain approval
rights PHLLC currently has with respect to significant actions taken by PIMCO
Advisors and Pacific Investment Management Company, Allianz AG has agreed to
compensate PAM if specified material business actions by PacPartners, PIMCO
Advisors or Pacific Investment Management Company authorized by Allianz AG or
any of its affiliates cause a decline in excess of $1 million per year in the
annual distributions on the Advisors Class E Units held by PacPartners. This
agreement was intended to provide PAM with a variable component of its
distributions that is based on PIMCO Advisors' historic fixed income asset
management business. These material business actions include:

  .  the incurrence of indebtedness by PacPartners or PIMCO Advisors;

  .  increases in bonuses payable under the Pacific Investment Management
     Company profit sharing plan;

  .  any sale or other disposition of assets of Pacific Investment Management
     Company;

  .  any sale or pledge by PIMCO Advisors of its capital or profits interests
     in Pacific Investment Management Company (other than pursuant to the
     Class B Unit Purchase Plan);

  .  the issuance of capital or profits interests in PIMCO Advisors or
     Pacific Investment Management Company or the amendment of any previously
     issued interests (other than pursuant to the Class B Unit Purchase
     Plan);

  .  any material restructuring of the business, assets or operations of
     Pacific Investment Management Company; and

  .  any other action which, prior to its implementation, is reasonably
     specified in a notice by PAM to Allianz AG as one which is likely to
     result in a material reduction of cash distributions with respect to
     Advisors Class E Units.

   Except in the case of a sale of the Advisors Class E Units pursuant to the
put/call agreement with Allianz of America, PAM has agreed not to permit a sale
or other transfer or disposition of any of the Advisors Class E Units held by
PacPartners and PacFin without the prior approval of PHLLC.

   Discussions with Allianz. PMHC from time to time considers potential
business opportunities, including possible alignments and combinations with
business partners, in the ordinary course of its business planning. At times
during Allianz AG's negotiations of the transaction with the Partnership,
Allianz AG and PMHC started separate discussions regarding a possible
acquisition of PMHC by Allianz AG. The discussions between Allianz AG and PMHC
have occurred from time to time from April 1999 through the present, and have
involved meetings of executive officers of Allianz AG and PMHC as well as their
respective financial and legal advisors. Additionally, after execution of a
confidentiality agreement, Allianz AG and PMHC have made available to each
other requested information regarding their respective businesses. The
discussions have not resulted in any agreement between Allianz AG and PMHC
regarding a separate Allianz AG/PMHC transaction, nor can we assure you that an
agreement will be reached. Neither the Closing nor the treatment of PAM's
Advisors Class A Units in the transactions contemplated by the merger agreement
is in any way contingent on Allianz AG and PMHC reaching an agreement with
respect to a separate transaction.

   Employment Termination Agreements. At the time of the Closing, PHLLC,
directly and through its interest in Partners GP, will own 17,402,107 Advisors
Class A Units and one PIMCO Advisors general partner unit. PHLLC is the obligor
under the 1994 Employment Termination Agreements, which were entered into in
1994 as part of the consolidation which created the PIMCO Advisors business
when the persons then serving as managing directors of Pacific Investment

                                       78

Management Company ceased to be employees of an affiliate of the predecessor to
Pacific Life and became employees of Pacific Investment Management Company. In
connection with that termination of employment, the predecessor of PHLLC agreed
to make noncompete payments to the managing directors equal to the
distributions on, or sale proceeds of, certain of the PIMCO Advisors units
beneficially owned by PHLLC through its interest in Partners GP. The
predecessor to PAM, another subsidiary of Pacific Life, guaranteed performance
of PHLLC under the 1994 Employment Termination Agreements. Currently, these
payments are based on the distributions on, or sale proceeds of, 17,402,107
Advisors Class A Units, which at the Closing will be all of the Advisors Class
A Units beneficially owned by PHLLC.

   Allianz GP Sub will purchase PHLLC for nominal consideration of $100, and
will then enter into amendments to the 1994 Employment Termination Agreements
with the eight members of Partners LLC who are parties to such contracts and
who are still acting as managing directors of Pacific Investment Management
Company and one former managing director of Pacific Investment Management
Company. The amendments will have the effect of releasing PAM from any further
liability under those 1994 Employment Termination Agreements which have been
amended. In addition, each of Allianz of America and certain managing directors
of Pacific Investment Management Company will agree to a reduction in certain
payments due to them to compensate PAM and its affiliates for one-third of any
future liabilities arising in connection with the one 1994 Employment
Termination Agreement which will not be amended at the Closing. See "--Partners
LLC--Employment Termination Agreements" for more information about the 1994
Employment Termination Agreements.

   Indemnification and Insurance. In addition, PHLLC, PAM, Partners GP and each
of their respective officers, directors, members, partners or other controlling
persons will have the benefit of the indemnification and insurance previously
described under "--The Partnership--Indemnification and Insurance."

                         CERTAIN FINANCIAL PROJECTIONS

   The Partnership does not as a matter of course publicly disclose internal
budgets, plans, estimates, forecasts or projections of future revenues,
earnings or other financial information. The projected financial data set forth
below were based upon a variety of estimates and assumptions, of which the
material items are set forth below. The estimates and assumptions underlying
the projections involved judgments with respect to, among other things, future
economic, competitive, and financial market conditions and future business
decisions which may not be realized and are inherently subject to significant
business, economic and competitive uncertainties, all of which are difficult to
predict and many of which are beyond the control of the Partnership. While the
Partnership believes these estimates and assumptions are reasonable, there can
be no assurance that the projections will be accurate, and actual results may
vary materially from those shown. In light of the uncertainties inherent in
forward looking information of any kind, the inclusion of these projections
herein should not be regarded as a representation by the Partnership, PIMCO
Advisors or any other person that the indicated results will be achieved, and
investors are cautioned not to place undue reliance on such information.

   The Partnership does not intend to update or otherwise revise the
information set forth below to reflect circumstances existing after the date of
the most recent financial statements incorporated by reference in this proxy
statement or to reflect the occurrence of unanticipated events. The information
set forth below should be read together with the information contained in the
Partnership's Annual Report on Form 10-K for the year ended December 31, 1998,
the Partnership's Quarterly Reports on Form 10-Q for the quarters ended March
31, 1999, June 30, 1999 and September 30, 1999 and the other information
included or incorporated by reference in this proxy statement.

   The projections set forth below are based on the following material
assumptions:

 .  Managed assets--a growth rate of 13.0% in PIMCO Advisors' aggregate assets
   under management, including a growth rate of 15.8% for those assets under
   management that are mutual fund assets. These growth rate assumptions
   reflect higher historical growth rates adjusted downward for current market
   conditions.

 .  Revenues--investment advisory fees would be .347% of assets under management
   and distribution and servicing fees would be .115% of the mutual fund assets
   under management, which reflect an approximation of these relationships.

 .  Operating profit available for distribution--OPAD margin, reflecting OPAD as
   a percentage of revenues, of 33%, which approximates the historical
   relationship of OPAD and revenues, exclusive of non-recurring items.

   In addition, these projections do not reflect non-recurring charges, such as
the costs associated with the proposed transaction which are estimated to be in
the range of $20 to $25 million.

                              REGULATORY APPROVALS

   Under the laws of some foreign nations, PIMCO Advisors is required to notify
certain governmental agencies, entities or regulatory authorities of the
transactions contemplated by the merger agreement. In particular, under the
laws of each of the following countries, the designated agency has been or will
be notified of the merger and the related transactions:

  .  in England, the Investment Management Regulatory Organisation Limited;

  .  in Ireland, the Central Bank of Ireland;

  .  in Japan, the Kanto Local Finance Bureau;

  .  in Canada, the Ontario Securities Commission; and

  .  in Chile, the Chilean Risk Rating Commission.

Additionally, in some nations the merger and related transactions may not be
consummated unless certain approvals are obtained from these nations'
regulatory authorities. In particular, under the laws of Singapore, a filing
for pre-merger approval of a change in control has been or will be made to the
Monetary Authority of Singapore, and under the laws of England, a filing for
pre-merger approval of a change in control has been or will be made to
Investment Management Regulatory Organisation Limited. These filings are still
pending. We cannot predict whether we will obtain all the required regulatory
approvals within the time frame contemplated by the merger agreement or without
incurring burdensome conditions.

             MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

   The following is a discussion of the material United States federal income
tax consequences of the merger to holders of Partnership units and is for
general information only. This discussion is based on the provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), the Treasury
Regulations promulgated thereunder, and judicial and administrative rulings and
decisions as of the date hereof, all of which are subject to change or
differing interpretations at any time, possibly with retroactive effect.
Furthermore, no rulings regarding the tax consequences of the merger have been
or will be sought from the Internal Revenue Service ("IRS"), and no one can be
sure that the IRS will not take a view that is contrary to that expressed
herein. The tax treatment of a holder of Partnership units may vary depending
upon his or her particular situation. Certain holders (including partnerships,
insurance companies, tax-exempt organizations, financial institutions, broker-
dealers, persons holding Partnership units as part of a "hedge," "straddle," or
"synthetic security transaction," and foreign holders) may be subject to
special rules not discussed below. This discussion does not consider the effect
of any state, local or foreign tax laws or any United States tax considerations
(e.g., estate or gift) other than United States federal income tax
considerations that may be relevant to particular holders. This discussion is
limited to holders who have held their Partnership units as "capital assets"
(generally property held for investment) within the meaning of Section 1221 of
the Code. EACH HOLDER OF PARTNERSHIP UNITS IS URGED TO CONSULT HIS OR HER TAX
ADVISOR WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN INCOME TAX AND
REPORTING CONSEQUENCES ARISING FROM THE MERGER AS THEY MAY RELATE TO HIS OR HER
TAX SITUATION.

                                       83
<PAGE>

Conversion of Partnership Units into Cash

   A holder who receives cash upon the conversion of Partnership units pursuant
to the merger will recognize gain or loss for United States federal income tax
purposes equal to the difference between (i) the sum of (A) the amount of cash
received and (B) the holder's share of the Partnership's liabilities, and (ii)
the holder's adjusted tax basis in such Partnership units so converted. Subject
to the rules described in the next paragraph, any such gain or loss will
generally constitute long-term capital gain or loss if the holder has held the
Partnership units for more than one year.

   A holder of Partnership units will, however, be required to recognize
ordinary income rather than capital gain to the extent any cash received upon
the conversion of such Partnership units pursuant to the merger is attributable
to amortization deductions that have been allocated to such holder related to
(i) goodwill of the Partnership that is eligible for amortization pursuant to
Section 197 of the Code, and (ii) other unrealized receivables and inventory of
the Partnership within the meaning of Section 751 of the Code (which amount
attributable to such other unrealized receivables and inventory is not expected
to be material to a holder of Partnership units). Such ordinary income may
exceed net gain realized upon the conversion of the Partnership units and may
be recognized even if there is a net loss on the conversion of the Partnership
units.

Backup Withholding

   The Partnership unitholders may be subject to backup withholding at the rate
of 31% with respect to the gross proceeds from the conversion of such
Partnership units pursuant to the merger unless such holder (i) is a
corporation or other exempt recipient and, when required, establishes this
exemption or (ii) provides his or her correct taxpayer identification number
(which, in the case of an individual, is his or her social security number),
certifies that he or she is not currently subject to backup withholding and
otherwise complies with applicable requirements of the backup withholding
rules. A unitholder who does not provide the Partnership with his or her
correct taxpayer identification number may be subject to penalties imposed by
the IRS. Any amount withheld under these rules will be creditable against the
holder's federal income tax liability, and if withholding results in an
overpayment of taxes, the holder may apply for a refund.

                            FINANCING FOR THE MERGER

   The merger is not conditioned upon Allianz of America obtaining financing.
The obligations of Allianz of America and its affiliates under the merger
agreement, including their payment obligations, have been guaranteed by Allianz
AG. The total amount of funds required at the closing to consummate the merger
and the transactions contemplated by the merger agreement and to pay estimated
fees and expenses for which Allianz of America and its affiliates are
responsible is approximately $2.9 billion. The source of all or part of the
funds required may be the proceeds from the sale of debt securities by Allianz
AG and otherwise will be from working capital of Allianz AG and its
subsidiaries.

                       LITIGATION CHALLENGING THE MERGER

   Following the announcement of the execution of the merger agreement, several
purported class actions were filed in the Court of Chancery of the State of
Delaware (the "Court of Chancery"). On November 19, 1999, the Court of Chancery
entered an Order consolidating all of the actions filed in the Court of
Chancery under the caption In re Pimco Advisors Holdings L.P. Shareholders
Litigation, CA No. 17511 (the "Delaware Action") In addition, a purported class
action was filed in the

                                       84
<PAGE>

Superior Court of Orange County, California (the "Orange County Action"). The
complaints name William D. Cvengros, Kenneth M. Poovey, Robert M. Fitzgerald,
PIMCO Partners, G.P., PIMCO Advisors Holdings L.P., PMHC and Allianz AG as
defendants. The complaints allege, among other things, various breaches of
fiduciary duty, conflicts of interest and unfair dealing in connection with the
merger agreement and the transactions contemplated thereby. The alleged
wrongful acts by defendants include allegations that PMHC and the individual
defendants agreed to an unfair cash-out price because they suffered from
conflicts of interest, that because of their continuing participation in PIMCO
Advisors after the merger they had no motivation to ensure maximum value to the
public unitholders, that they did not comply with alleged fiduciary duties to
maximize unitholder value, and that Allianz AG knowingly aided and abetted the
alleged breaches of fiduciary duty committed by PMHC and the individual
defendants. The complaints seek compensatory and/or rescissionary money damages
or, alternatively, injunctive relief or rescission of the transaction.

   The Orange County Action has been stayed pending the completion of the
Delaware Action. The time for defendants to respond to the complaint in the
Delaware Action has been extended to March 6, 2000.

   During the period from November 1999 through February 23, 2000, counsel for
the respective parties engaged in discussions regarding the possible settlement
of the Delaware Action. On or about February 23, 2000, the parties entered into
a Memorandum of Understanding.

   The Memorandum of Understanding provides for certification of a settlement
class defined to include all persons, except defendants and the immediate
families of individual defendants, who were record or beneficial owners of
Partnership units at any time during the period from October 31, 1999 to and
including the date of the filing of the certificate of merger for the
Partnership merger as well as their legal representatives, heirs, successors in
interest, transferees and assigns.

The Memorandum of Understanding provides that:

  .  the amount of the termination fee (described in "The Merger Agreement--
     Termination Fee") shall be reduced from $180,000,000 to $120,000,000;

  .  the potential downward adjustment to the Unit Price (described in "The
     Transaction--The Merger: The Acquisition of the Partnership--Adjustment
     to Unit Price") will be modified so that, if PIMCO Advisors' revenue
     base, expressed as a revenue run-rate, as of the calendar month-end
     immediately prior to the Closing is less than 85% of the revenue run-
     rate on September 30, 1999, the Unit Price will be reduced by 1.8%
     (rather than 2% as originally provided in the merger agreement) for each
     1% that the revenue run-rate falls below 85%, subject to a maximum
     reduction of 18% (rather than 20%) (i) for all Partnership units and all
     PIMCO Advisors units to be cancelled and exchanged for cash in the
     Partnership and PIMCO Advisors mergers, and (ii) in the calculation of
     amounts to be paid in respect of each outstanding unit option, deferred
     unit, deferred compensation unit and vested deferred restricted unit in
     the Deferred Compensation Plan and the principal amount of the note to
     be received from Allianz of America in respect of the unvested
     restricted units in the Deferred Compensation Plan; except that the Unit
     Price to be paid (A) for PIMCO Advisors units held by any person who was
     a member of Partners LLC on October 31, 1999 (the date the mergers were
     approved), (B) for PIMCO Advisors units held by NFJ Partners L.P.,
     Parametric Partners L.P. and Cadence Partners L.P., the beneficial
     interest in which is held solely by the respective general partner in
     each such partnership, (C) in satisfaction of each 1994 Employment
     Termination Agreement between PHLLC and a present or former

                                       85
<PAGE>

     managing director of Pacific Investment Management Company that will be
     amended in connection with the transactions, and (D) in respect of each
     outstanding unit option, deferred unit, deferred compensation unit and
     vested deferred restricted unit that is held by, or in which a
     beneficial interest is held by, a member of Partners LLC, shall be
     calculated without regard to this modification;

  .  five business days prior to the special meeting, PIMCO Advisors shall
     issue a press release stating its revenue-run rate in relation to its
     September 30, 1999 revenue run-rate as of the nearest month-end
     preceding the date of the press release, provided that if such press
     release would be required to be issued in the first five business days
     after a calendar month-end, the revenue run-rate as of the immediately
     preceding month-end shall be used; and

  .  the proxy statement will contain certain additional disclosure. (Such
     additional disclosure is contained herein.)

   In addition, pursuant to the Memorandum of Understanding, PIMCO Advisors
will pay such counsel fees of the settlement class as may be awarded by the
court in an amount not to exceed $1,250,000, plus expenses actually incurred in
an amount not to exceed $250,000. Payment of such fees and expenses is
contingent on the closing of the merger.

   The Memorandum of Understanding provides for the dismissal of the Delaware
Action with prejudice. The Memorandum of Understanding also provides for the
release of all claims of members of the settlement class, whether known or
unknown, against the defendants in the Delaware Action and any of their
affiliates (as defined to include defendants' present or former officers,
directors, employees, agents, attorneys, advisors, insurers, accountants,
trustees, financial advisors, commercial bank lenders, persons who provided
opinions relating to the merger, investment bankers, associates,
representatives, affiliates, parents, subsidiaries, general partners, including
PHLLC and Partners LLC, limited partnership partners, partnerships, heirs,
executors, personal representatives, estates, administrators, successors and
assigns and including any directors, officers, agents, partners, members,
managers, or employees of any of the foregoing) arising out of or relating to,
among other things, the merger agreement, the merger and the other transactions
contemplated by the merger agreeement, the unitholders' meeting, the proxy
statement and any other disclosures with respect to the foregoing. The
settlement is contingent upon, among other things, court approval.

                 EFFECT OF THE MERGER ON THE PARTNERSHIP UNITS

   The Partnership units are currently listed on the New York Stock Exchange.
Following the completion of the merger and the other transactions contemplated
by the merger agreement, the Partnership units will no longer be traded on the
New York Stock Exchange, price quotations will no longer be available for the
units and the registration of the Partnership units under the Exchange Act will
be terminated.

                              THE MERGER AGREEMENT

   The following is a brief summary of the material provisions of the merger
agreement, a copy of which is attached as Appendix A and is incorporated by
reference in this proxy statement. The summary is qualified in its entirety by
reference to the merger agreement. We urge you to read the merger agreement in
its entirety for a more complete description of the terms and conditions of the
merger.

The Merger and Subsequent Transactions

   The merger agreement provides for the acquisition of the Partnership by
Allianz of America through a merger of an indirect subsidiary of Allianz of
America with and into the Partnership. In the merger, all of the outstanding
limited partner and general partner units in the Partnership will be converted
into the right to receive cash in an amount per unit equal to $38.75, subject
to adjustment as described in "The Transaction" (the "Unit Price").

   As a result of the merger, the Partnership will become an indirect wholly-
owned subsidiary of Allianz of America.

   As a result of the merger, all of our equity interests will be indirectly
owned by Allianz of America. In addition, you will no longer have any interest
in, and will not be a unitholder of, the Partnership, and therefore will not
participate in our future earnings and growth. Instead, you will have the right
to receive the cash consideration described above for each unit held. In
addition, the Partnership units will no longer be traded on the New York Stock
Exchange, price quotations of the Partnership units will no longer be available
and the registration of the Partnership units under the Securities Exchange Act
of 1934 will be terminated.

   Following the merger, subsidiaries of Allianz of America will, in a series
of transactions, acquire substantially all of the remaining interests in PIMCO
Advisors, other than those beneficially owned by Pacific Life. As a result of
the transactions, Allianz of America will control PIMCO Advisors, having
acquired approximately 70% of the outstanding partnership interests of PIMCO
Advisors.

   On March 3, 2000 the parties entered into an amendment to the merger
agreement effecting certain of the agreements reached in the settlement of the
unitholder litigation described in "Litigation Challenging the Merger." The
amendment provides for modification of the potential downward adjustment to the
Unit Price effective upon satisfaction of all of the terms of the settlement,
reduction of the termination fee payable by PIMCO Advisors to Allianz of
America in certain circumstances effective upon court approval of the
settlement and allocation of certain legal expenses. In addition, the amendment
adds certain newly-formed entities described under "The Transaction" as parties
to the merger agreement and updates Annex A to the merger agreement.

   See "The Transaction" for a description of the merger, possible adjustments
to the Unit Price, and the transactions following the merger.

Covenants

   Conduct of Parties Prior to Closing. Prior to the Closing, the Partnership,
PIMCO Advisors, Partners GP and PHLLC have agreed to conduct their businesses,
and those same entities, along with PAM and Partners LLC, have agreed to
conduct the businesses of their respective subsidiaries in the ordinary course
of business; to preserve their business organizations and assets intact; and to
maintain existing business relations and goodwill. They have also agreed to
take certain actions only after obtaining the prior written consent of Allianz
of America.

   Acquisition Proposals. The Partnership, PIMCO Advisors, PAM, Partners GP,
Partners LLC and PHLLC have agreed to terminate any activities, discussions or
negotiations with any parties other than Allianz AG and Allianz of America
regarding an acquisition proposal, as described below. They have also agreed
that they will not, except as permitted in the following paragraph:

  .  initiate or solicit any inquiry or the making of an acquisition proposal
     or otherwise facilitate any effort or attempt to make or implement an
     acquisition proposal; or

  .  engage in any negotiations concerning, or provide any confidential
     information to, or have any discussions with, any third party regarding
     an acquisition proposal.

   However, the Partnership, its management board and its representatives may
take any actions necessary to comply with Rule 14e-2 of the Exchange Act
relating to tender offers. In addition, if the managing member, general partner
or board of any of PIMCO Advisors, the Partnership, PAM, Partners GP, Partners
LLC or PHLLC determines in good faith, after consultation with its advisers,
that an acquisition proposal is reasonably capable of being consummated and
would, if consummated, result in a transaction more favorable to the
Partnership's unitholders than the merger with Allianz of America from a
financial point of view, then the entity may:

  .  provide information or engage in negotiations with a third party that
     has made an unsolicited written bona fide acquisition proposal; and

  .  recommend a competing acquisition proposal to the members, partners or
     unitholders, as applicable, and withdraw its prior recommendation of the
     merger agreement with Allianz of America, subject to the termination
     provisions described below under "Termination--Termination."

   PIMCO Advisors, the Partnership, PAM, Partners GP, Partners LLC and PHLLC
have agreed to notify Allianz AG and Allianz of America within one day of
receipt if any acquisition proposal is received, if any request for non-public
information relating to an acquisition proposal is received or if discussions
or negotiations are sought to be initiated with respect to an acquisition
proposal. The notification must identify the party making the proposal or offer
and the material terms and conditions of the proposal or offer.

   As used in the merger agreement and this proxy statement, the term
"acquisition proposal" means any proposal or offer with respect to a merger,
reorganization, share exchange, consolidation or similar transaction involving,
or any purchase of all or any significant portion of the assets or equity
interests in, any of PIMCO Advisors, the Partnership, PAM, Partners GP,
Partners LLC and PHLLC or, with certain specific exceptions, any of their
subsidiaries.

   Employment Benefits and Agreements; Changes at Pacific Investment Management
Company. The parties have agreed to establish:

  .  the PIMCO Advisors L.P. Transition and Retention Plan, for key employees
     of PIMCO Advisors and its subsidiaries other than Pacific Investment
     Management Company; and

                                       89
<PAGE>

  .  the PIMCO Advisors Retention Plan for executives of Pacific Investment
     Management Company.

   In addition, the parties have agreed to a reorganization of Pacific
Investment Management Company into a limited liability company, with PIMCO
Advisors as the managing member. The structural management rights of the PIMCO
Managing Directors will be replaced by a revocable delegation by PIMCO Advisors
to the PIMCO Managing Directors of management rights similar to those they
currently enjoy. In addition, the PIMCO Profit Sharing Plan will be amended to
reduce the profit sharing pool from 45% to 30% of adjusted net profits over
five years, and to adopt a Class B Unit Purchase Plan giving executives of
Pacific Investment Management Company the right to buy over a five year period
interests in Pacific Investment Management Company bearing distributions equal
in aggregate to 15% of the adjusted net profits of Pacific Investment
Management Company. Also, the PIMCO Managing Directors and certain executive
officers of the Partnership will enter into new employment agreements in
connection with the Closing. More information about these matters can be found
in "Special Factors--Interests of Certain Persons in the Transaction--The
Partnership" and "--Partners GP--Partners LLC."

   Filings, Other Actions, Notification. Each of the Partnership, PIMCO
Advisors, PAM, Partners GP, Partners LLC and PHLLC and Allianz of America has
agreed to cooperate with each other and to use their respective reasonable best
efforts to cause all actions to be taken to consummate the transactions
proposed by the merger agreement, including preparing and filing all
documentation necessary to obtain the approvals and authorizations of all third
parties and government entities as required to consummate the transactions in
the merger agreement.

   Each of PIMCO Advisors, the Partnership, PAM, Partners GP, Partners LLC and
PHLLC has agreed to give Allianz of America and Allianz of America has agreed
to give each of PIMCO Advisors, the Partnership, PAM, Partners GP, Partners LLC
and PHLLC notice of any of the following:

  .  any event or condition that would cause any of such party's
     representations and warranties to be inaccurate or incomplete in any
     material respect;

  .  any failure of a party to comply with any material covenant or agreement
     in the merger agreement;

  .  any material default or potential event of default under a key contract;

  .  any material written notice or communication from a third party alleging
     that the third party's consent is required in connection with the merger
     transactions; and

  .  any change that is reasonably likely to result in a material adverse
     effect.

   Finally, each of the Partnership, PIMCO Advisors, PAM, Partners GP, Partners
LLC and PHLLC have agreed to use their reasonable best efforts to obtain the
consents and approvals necessary to assign any agreements, including the
advisory agreements, affected by the merger.

   Investment Company Matters. Each of the parties to the merger agreement has
agreed to use its reasonable best efforts, both before and after the Closing,
to ensure compliance with the Investment Company Act as it applies to the
change in control of PIMCO Advisors and certain subsidiaries that act as
investment advisers to registered investment companies. PIMCO Advisors and its
general partners have also agreed to use their reasonable best efforts to
ensure that the sponsored registered and non-registered investment companies
referred to in the merger agreement do not take actions that may have specified
adverse effects on those investment companies.

   Advisory Agreements. PIMCO Advisors has agreed to notify, and to cause each
of its subsidiaries that is a registered investment adviser to notify, their
respective clients of the transactions contemplated by the merger agreement and
to use its reasonable best efforts to obtain, prior to the Closing, the consent
of those clients to the assignment of its advisory agreement.

   Taxation. Allianz of America has agreed to prepare and file all tax returns
for any partial period ending on or before the Closing for each of the
Partnership, PIMCO Advisors and its subsidiaries, Partners GP and PHLLC. PAM
and the representatives of the PIMCO Managing Directors will have the right to
review and approve these tax returns before they are filed.

   Access; Information. The Partnership, PIMCO Advisors and Partners GP have
each agreed to allow Allianz AG and Allianz of America access to their and
their subsidiaries' books, records, offices, properties and personnel, and
access to information reasonably requested by Allianz AG or Allianz of America.
The parties have agreed that none of this information will be used for any
purpose unrelated to the consummation of the transactions contemplated by the
merger agreement and each party shall keep this information confidential.

   Publicity. PAM, PIMCO Advisors, Partners LLC and Allianz of America have
agreed to consult with each other prior to issuing any press releases or making
any public announcements regarding the merger agreement and prior to making any
filings with any government authority or self-regulating organization with
respect to the merger agreement.

   Effect of Investigation. The representations and warranties made by a party
will not be affected by and will survive any investigation by another party.

of the merger transactions each of the Partnership, PIMCO Advisors, PAM,
Partners GP, Partners LLC and PHLLC and each of their respective boards,
general partners, managing members and managing boards has agreed to take the
actions necessary to eliminate or minimize the effects of the statute or
regulation on the merger transaction.

   Reasonable Best Efforts. Each of the Partnership, PIMCO Advisors, PAM,
Partners GP, Partners LLC and PHLLC and Allianz of America have agreed to use
their reasonable best efforts to, and to cause each of their subsidiaries to,
take all actions necessary or desirable to fulfill the conditions and

     Agreement providing for the put and call rights on the Advisors Class E

     Investment Management Company into a limited liability company; and

by Allianz of America or by the Partnership, PIMCO Advisors, PAM and Partners
LLC if:

  .  the transactions contemplated by the merger agreement have not been

     modified its approval or recommendation of the merger agreement,
     Partners GP has failed to reconfirm its recommendation of the merger
     agreement or the merger within five days of being requested by the

     to the Partnership's unitholders;

  .  any of the Partnership, PIMCO Advisors, PAM, Partners GP, Partners LLC
     or PHLLC has breached a representation, warranty, covenant or agreement

     after notice by Allianz of America; or

                                       94
<PAGE>

  .  the revenue run-rate (calculated to exclude market movements) at the end
     of any two consecutive calendar months prior to the effective time of
     the merger is less than 75% of the revenue run-rate as of September 30,
     1999; or

by PAM and Partners LLC if:

  .  (a) the management board, general partner or managing member of the
     Partnership, PIMCO Advisors, PAM, Partners GP, Partners LLC or PHLLC
     authorizes that entity to recommend or enter into a binding agreement
     concerning an acquisition proposal that PAM and Partners LLC determine,
     in good faith, after consultation with their advisors, is an acquisition
     proposal superior to that provided in the merger agreement; and

     favorable as the superior proposal within five days of notice of the
     superior proposal; and

   Termination Fee. PIMCO Advisors has agreed to pay Allianz of America a
termination fee of $180 million ($120 million if the unitholder litigation
settlement is approved) if either of the following events occur:

  .  the merger agreement is terminated by PAM and Partners LLC because of
     the recommendation of or entry into an agreement regarding a superior
     acquisition proposal, or

     Partners GP failed to recommend, withdrew or adversely modified its
     approval or recommendation of the merger agreement, (2) Partners GP
     failed to reconfirm its recommendation of the merger agreement or the
     merger within five days of being requested by the Partnership to do so,
     or (3) Partners GP has recommended a superior proposal to the

     Advisors, PAM, Partners GP, Partners LLC or PHLLC enters into a binding
     agreement with a third party to implement a different acquisition
     proposal.

   Each of the Partnership, PIMCO Advisors, PAM, Partners GP, Partners LLC and
PHLLC and Allianz of America believe that the termination fee is an integral
part of the transactions and have acknowledged that Allianz of America and its
related entities would not have entered into the merger agreement without the
establishment of the termination fee.

Amendment and Waiver

     merger agreement; or

of the merger agreement if the amendment or modification (1) occurs after the
Partnership's unitholders have approved the merger agreement and the amendment
or modification changes the amount or kind of

                                       95
<PAGE>

consideration to be received by the unitholders, (2) could reasonably be
expected to materially delay or impede the Closing, or (iii) would constitute a
waiver of any provision of the merger agreement other than a waiver by the
party benefited by the provision.

the rights and obligations of any of its subsidiaries under the merger
agreement to another direct or indirect subsidiary of Allianz of America upon
written notice to PIMCO Advisors, if the guarantee of those obligations

           CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

   The Partnership has made forward-looking statements in this document and the
documents incorporated by reference herein that are subject to risks and
uncertainties. These statements are based on management's beliefs and
assumptions, based on information currently available to management. Forward-
looking statements include the information concerning possible or assumed
future results of operations of the Partnership set forth (i) under "Summary,"
"Special Factors" and "The Transaction," (ii) under "Business" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in the Partnership's Annual Report on Form 10-K and Quarterly

this document and the documents incorporated herein by reference preceded by,
followed by or that include the words "believes," "expects," "anticipates,"
"intends," "plans," "estimates," "should" or similar expressions.

   Some statements contained in this proxy statement may constitute "forward
looking statements" within the meaning of the Private Securities Litigation
Reform Act of 1995. These statements involve a number of risks, uncertainties
and other factors that could cause actual results to differ materially,
including the performance of financial markets, the investment performance of
PIMCO Advisors' sponsored investment products and separately managed accounts,
general economic conditions, future acquisitions, competitive conditions and
government regulations, including changes in tax laws. The Partnership cautions
you to carefully consider such factors. Further, such forward-looking
statements speak only as of the date on which such statements are made. The
Partnership undertakes no obligation to update any forward-looking statements
to reflect events or circumstances after the date of such statement even if new
information, future events or other circumstances have made them incorrect or
misleading. For those statements, the Partnership claims the protection of the
safe harbor for forward-looking statements contained in the Private Securities
Litigation Reform Act of 1995.

   Unitholders should understand that the following important factors, in
addition to those discussed elsewhere in the documents which are incorporated
by reference into this proxy statement, could affect the future results of the
Partnership and could cause results to differ materially from those expressed
in such forward-looking statements:

  .  competitive pressures among financial services companies may increase
     significantly;

  .  general economic conditions, either internationally or nationally or in
     the states in which the Partnership is doing business, may be less
     favorable than expected;

                                      104
<PAGE>

  .  legislative or regulatory changes may adversely affect the business in
     which the Partnership is engaged; and

  .  technological changes (including "Year 2000" data systems compliance
     issues) may be more difficult or expensive than anticipated.

    the Paying Agent to make payments pursuant to Section 2.01(d)(i) to
    holders of Holdings LP Units issued and outstanding immediately prior
    to the Holdings LP Effective Time ("Holdings LP Unitholders").

       (ii) Payment Procedures. Promptly after the Holdings LP Effective
    Time, Holdings LP Surviving Partnership shall cause to be mailed to
    each Person who was, at the Holdings LP Effective Time, a holder of
    record of issued and outstanding Holdings LP Units (i) a letter of
    transmittal specifying that delivery shall be effected, and the risk of
    loss and title to each certificate representing Holdings LP Units shall
    pass, only upon delivery of such certificate (or affidavits of loss in
    lieu thereof) to the Paying Agent, such letter of transmittal to be in
    such form and have such other provisions as AZOA and Holdings LP may
    reasonably agree, and (ii) instructions for use in effecting the
    surrender of such certificates. Upon surrender to the Paying Agent of
    any such certificate, together with such letter of transmittal, duly
    executed and completed in accordance with the instructions thereto,
    Holdings LP Surviving Partnership shall promptly cause to be paid to
    the Person(s) entitled thereto, by check, the amount to which such
    Person(s) are entitled pursuant to Section 2.01(d)(i), after giving
    effect to any required tax withholding. No interest will be paid or
    will accrue on the amount payable upon the surrender of any such
    certificate. If payment is to be made to a Person other than the
    registered holder of a certificate surrendered, it shall be a condition
    of such payment that the certificate so surrendered shall be properly
    endorsed or otherwise in proper form for transfer and that the Person
    requesting such payment shall pay any transfer or other taxes required
    by reason of the payment to a Person other than the registered holder
    of the certificate surrendered or establish to the satisfaction of
    Holdings LP Surviving Partnership or the Paying Agent that such tax has
    been paid or is not applicable.

       (iii) Transfers. After the Holdings LP Effective Time, there shall
    be no transfers on the books and records of Holdings LP of the Holdings
    LP Units that were outstanding immediately prior to the Holdings LP
    Effective Time.

    Agent to deliver to it any funds (including any interest received with
    respect thereto) made available to the Paying Agent which have not been
    disbursed to Holdings LP Unitholders at the Holdings LP Effective Time,
    and thereafter such holders shall be entitled to look to Holdings LP
    Surviving Partnership only as general creditors thereof with respect to
    the cash payable upon due surrender of such certificates.
    Notwithstanding the foregoing, neither the Paying Agent nor any party
    hereto shall be liable to any holder of such certificates for any
    amount paid to a public official pursuant to any applicable abandoned
    property, escheat or similar law. Holdings LP Surviving Partnership
    shall pay all charges and expenses, including those of the Paying
    Agent, in connection with the payment of cash in exchange for Holdings
    LP Units.

       (v) Lost, Stolen or Destroyed Holdings LP Certificates. In the event

    and, if required by Holdings LP, the posting by such Person of a bond
    in customary amount as indemnity against any claim that may be made

    due surrender of the Holdings LP Units represented by such certificate.

       (v) except as Previously Disclosed, as provided under any
    Compensation and Benefit Plan Previously Disclosed as in effect on the
    date hereof or as contemplated by a Transaction Document, the
    consummation of the Transactions would not, directly or indirectly

      fact or omit to state any material fact necessary in order to make
      the statements made therein, in the light of the circumstances under
      which they were made, not misleading or necessary to correct any
      statement or any earlier communication with respect to the
      solicitation of a proxy for the same meeting or subject matter which
      has become false or misleading;

         (K) except as Previously Disclosed and made available to AZOA, as
      of the date hereof, no exemptive orders have been obtained, nor are
      any requests pending therefor, with respect to any Sponsored
      Registered Investment Company under any of the Securities Laws;

      each of which has been provided or made available to AZOA and each

      Advisors LP and each such Subsidiary with respect to avoiding

      has any express or implied understanding or arrangement which would

      Investment Companies or would in any way violate Section 15(f) of
      the Investment Company Act as a result of any of the Transactions;

         (N) neither Advisors LP, any of its Subsidiaries, the Sponsored

      than five (5) years prior to the date hereof been convicted of any
      crime or is or has been subject to any disqualification that would
      be a basis for disqualification as an investment adviser to any
      Investment Company pursuant to Section 9(a) of the Investment
      Company Act, and to such Seller's knowledge there is no basis for,
      or proceeding or investigation that could become the basis for, any
      such disqualification.

   4.02 Acquisition Proposals. Each of the Sellers agrees that it will not and
will cause each of its Subsidiaries, if any, and its and any such Subsidiaries'
respective executive officers and directors not to, and each such Seller agrees
to direct its and any such Subsidiaries' employees, agents and representatives
(including, without limitation, any investment banker, attorney or accountant

or indirectly, any inquiries or the making of any proposal or offer (including,
without limitation, any proposal or offer to stockholders, members or

consolidation or similar transaction involving, or any purchase of all or any
significant portion of the assets or any Equity Interests in, any Seller or any
of its Subsidiaries (in the case of PacMan, only including Holding LLC and its
Subsidiaries) other than PIMCO Trust Company and Columbus Circle Trust Company
(each such Person being referred to in this Section 4.02(a) as a "subject
Person" and any such proposal or offer being hereinafter referred to as an
"Acquisition Proposal") or directly or indirectly engage in any negotiations
concerning, or provide any confidential information or data to, or have any
discussions with, any Person relating to an Acquisition Proposal, or otherwise
facilitate any effort or attempt to make or implement an Acquisition Proposal;

complying with Rule 14e-2 promulgated under the Exchange Act with regard to an
Acquisition Proposal or providing any other legally required disclosure to the

extent that, in each such case referred to in clause (B) or (C) above, such
managing member, general partner or board determines in good faith, after
consultation with its advisers, including its outside counsel, that such
Acquisition Proposal, if accepted, is reasonably capable of being consummated,
taking into account all legal, financial and regulatory aspects of the proposal
and would, if consummated, result in a transaction more favorable to such
Seller's members or unitholders, as the case may be, from a financial point of
view than the transactions contemplated by this Agreement (any such more
favorable Acquisition Proposal being referred to in this Agreement as a
"Superior Proposal"). Each Seller agrees that it will notify Allianz and AZOA
promptly (within one business day of receipt) if any such inquiries, proposals
or offers are received by, any such information is requested from, or any such

of its representatives indicating, in connection with such notice, the name of
such Person and the material terms and conditions of any proposals or offers
and thereafter shall keep Allianz and AZOA reasonably informed on the status
and terms of any such proposals or offers and the status of any such
discussions or negotiations. Each such Seller shall, and shall cause each
Subsidiary to, immediately cease and cause to be terminated any activities,
discussions or negotiations conducted prior to the date of this Agreement with
any parties other than Allianz and AZOA with respect to any of the foregoing
and shall use its reasonable best efforts to enforce any confidentiality or
similar agreement relating to an Acquisition Proposal.

  advisable in connection with any statement, filing, notice or application
  required to be made by or on behalf of any of Allianz, AZOA, the Sellers,

  qualifying as a "regulated

                                      A-46
<PAGE>

  investment company," within the meaning of Section 851 of the Code, (b)
  with respect to the Sponsored Non-Registered Investment Companies that are
  currently taxed as partnerships, take no action that would cause such a
  Sponsored Non-Registered Investment Company to be subject to taxation on a
  net income basis under the Code or (c) be inconsistent with any Sponsored
  Registered Investment Company's prospectus or other offering document and
  other offering, advertising and marketing materials.

   4.06 Advisory Agreements. Unless otherwise previously agreed to by AZOA,
Advisors LP shall and shall cause each Subsidiary of Advisors LP that is a

consent of each such Client (whether by affirmative consent or negative
consent, as applicable) to the "assignment" (as such term is used in the

Transactions in accordance with the Investment Advisers Act. Each of the
Sellers shall cooperate and consult with AZOA regarding material written
communications with Clients concerning the obtaining of such consents.

   4.07 Taxation.

  Tax law, be prepared and filed on a basis consistent in all material
  respects with the Tax Returns of the applicable Acquired Entity as prepared
  and filed in prior periods. Prior to filing such Tax Returns, AZOA will
  make any changes to such Tax Returns as are reasonably requested by PacMan
  or the MD Representatives, and for such purposes any such request shall be
  deemed reasonable to the extent it requests conformity to prior Tax Return
  positions as required under clause (ii) of the preceding sentence.

  as a partnership for U.S. federal income tax purposes, Holdings LP,

  Section 4.08 (as well as any other information obtained in connection with
  its consideration or consummation of any of the transactions contemplated
  by any of the Transaction Documents, including any information obtained
  prior to the date hereof) for any purpose unrelated to the consummation of
  the Transactions or the Transaction Documents. Subject to the requirements
  of law, each Party shall keep confidential, and shall cause its
  representatives to keep confidential, all information and documents

  such Party from other sources not known by such Party to be bound by a
  confidentiality obligation, (3) is disclosed with the prior written
  approval of the Party to which such information pertains or (4) is or
  becomes readily ascertainable from published information or trade sources.
  In the event that this Agreement is terminated or the Transactions shall
  otherwise fail to be consummated, each Party shall promptly cause all
  copies of documents or extracts thereof containing information and data as
  to any of the other Parties to be returned to the appropriate Party. No
  investigation by any Party of the business and affairs of any of the
  Parties and their respective Subsidiaries shall affect or be deemed to

  Proposal or (ii) there has been a breach by any Seller of any

   6.04 Termination by the Sellers. This Agreement may be terminated and the

     (a) if (i) the management board, general partner or managing member of

  and Partners LLC determine in good faith, after

                                      A-55
<PAGE>

  consultation with their advisers, constitutes a Superior Proposal, and such
  Seller notifies Allianz and AZOA in writing that it intends to enter into
  such an agreement, attaching the most current version of such agreement to
  such notice, (ii) AZOA does not make, within five business days of receipt
  of such Seller's written notification of its intention, an offer that the
  managing member, general partner or management board of such Seller
  determines, in good faith after consultation with its advisors, is at least
  as favorable, from a financial point of view, to the members, partners or
  unitholders, as the case may be, as the Superior Proposal and
  (iii) simultaneously with such termination such Seller pays or causes
  Advisors LP to pay to AZOA in immediately available funds the Termination
  Fee described in Section 6.06; or

     (b) if there has been a breach by AZOA of any covenant, representation,
  warranty or agreement contained in this Agreement that (x) would entitle
  PacMan and Partners LLC to assert that the conditions to its obligations
  hereunder set forth in Section 5.03(a) or (b) have not been satisfied and
  (y) is not curable or, if curable, is not cured within thirty (30) days
  after written notice of such breach is given by the PacMan and Partners
  LLC.

   6.05 Effect of Termination and Abandonment. In the event of termination of
this Agreement and the abandonment of the Transactions pursuant to this Article
VI, this Agreement (other than as set forth in Sections 6.06 and 7.01) shall
become void and of no effect with no liability on the part of any Party (or of
any of its directors, officers, employees, agents, legal and financial advisors
or other representatives); provided, however, except as otherwise provided
herein, no such termination shall relieve any Party of any liability or damages
resulting from any wilful breach of this Agreement.

   6.06 Termination Fee.

     (a) Upon the occurrence of a Fee Triggering Event, Advisors LP agrees
  and each of the Sellers hereby agrees, jointly and severally, to pay or to
  cause Advisors LP to pay AZOA, and AZOA shall be entitled to payment of, a
  fee of $180,000,000 (the "Termination Fee"). Except as provided in
  Section 6.04(a), such payment shall be made to AZOA in immediately
  available funds within three business days after the occurrence of the Fee
  Triggering Event.

     (b) The term "Fee Triggering Event" shall mean any of the following
  events or transactions occurring after the date hereof:

       (1) this Agreement is terminated by the Sellers pursuant to Section
    6.04(a); or

       (2) this Agreement is terminated by AZOA pursuant to Section
    6.03(a)(i) and, within 12 months after such termination, a Seller
    enters into a binding agreement with any Person providing for a
    transaction implementing an Acquisition Proposal.

     (c) Each of PacMan and Partners LLC shall notify AZOA promptly in
  writing of the occurrence of any Fee Triggering Event.

     (d) The payment by any Seller of the Termination Fee provided by this
  Section 6.06 shall constitute liquidated damages for any breach by any of
  the Sellers of this Agreement although a breach is not necessary for any
  payment to be required to be made under this Section 6.06.

     (e) Each of the Sellers acknowledges that the agreements contained in
  this Section 6.06 are an integral part of the Transactions and that,
  without these agreements, neither AZOA nor any of its Subsidiaries would
  have entered into this Agreement or any of the other Transaction Documents;
  accordingly, if Advisors LP fails, and the Sellers fail to cause Advisors
  LP, to promptly pay the amount due pursuant to this Section 6.06, and, in
  order to obtain such payment, AZOA or any of its Subsidiaries commences a
  suit which results in a judgment against

                                      A-56
<PAGE>

  the Sellers for the Termination Fee, the Sellers shall pay to AZOA its
  costs and expenses (including attorneys' fees) in connection with such
  suit, together with interest on the amount of the Termination Fee at the
  prime rate of Citibank N.A. in effect on the date such payment was required
  to be made.

2001 and the publication of the first annual audited financial statements of
Advisors LP and its Subsidiaries following the Closing, provided that the
representations and warranties contained in Section 3.03(t) (Taxes) shall
survive until the expiration of the relevant statutory periods. Sections 7.01,
7.03, 7.04, 7.05, 7.08 and 7.10, Sections 4.08(b) (Access; Information), 4.17
(Expenses), 6.05 (Effect of Termination and Abandonment) and 6.06 (Termination
Fee) shall survive the termination of this Agreement. All other covenants and

  Partnership Act or the DE LLC Law are applicable).

     (b) Each Party acknowledges and agrees that any controversy which may
  arise under the Transaction Documents is likely to involve complicated and
  difficult issues, and therefore each such Party hereby irrevocably and
  unconditionally waives any right such Party may have to a trial by jury in
  respect of any litigation directly or indirectly arising out of or relating

                               TRANSACTION STEPS
                         VERSION 23 (OCTOBER 31, 1999)

1. Allianz GP Sub forms (i) Advisors LP Merger Sub as a wholly-owned LLC
   subsidiary and (ii) Holdings LP General Partner as a wholly-owned LLC
   subsidiary. Allianz GP Sub and Holdings LP General Partner form Holdings LP
   Merger Sub as a limited partnership, with Allianz GP Sub holding the sole
   limited partner interest and Holdings LP General Partner holding the sole
   general partner interest. AZOA contributes cash and Allianz Stock to Allianz
   GP Sub (which, in turn, contributes cash to Advisors LP Merger Sub and
   Holdings LP Merger Sub) in an aggregate amount sufficient to satisfy all of
   Allianz GP Sub's, Advisors LP Merger Sub's and Holdings LP Merger Sub's
   obligations as described below.

2. Holdings LP Merger Sub merges into Holdings LP, with (i) Holdings LP
   surviving, (ii) Holdings LP partners (Partners GP (5,099 Holdings LP GP
   Units) and the public holders (49,553,023 Holdings LP Units as of September
   30, 1999)) receiving cash at the Unit Price in exchange for their Holdings
   LP Units and Holdings LP GP Units, (iii) Allianz GP Sub's limited partner
   interest in Holdings LP Merger Sub converting into a limited partner
   interest in Holdings LP and (iv) Holdings LP General Partner's general
   partner interest in Holdings LP Merger Sub converting into a general partner
   interest in Holdings LP.

3. Allianz GP Sub acquires Partners LLC's (i) 142,480 Class A Units for an
   amount of cash equal to the Unit Price multiplied by 142,480 and (ii)
   general partner interest in Partners GP for $100. Immediately thereafter,
   Partners LLC dissolves and distributes its cash to its members.

4. Partners GP converts all but one of its Advisors GP Units into 799,998 Class
   A Units.

5. Partners GP distributes (i) 37,584,048 Class A Units (all of its Class A
   Units other than 1,826,272 Class A Units relating to interests under the
   Holding LLC ETAs not held by PIMCO MDs), (ii) its Advisors GP Unit and (iii)
   the PPGP Note Agreement (if outstanding) to Holding LLC.

6. Holding LLC distributes (i) 22,008,213 Class A Units (all of its Class A
   Units other than 15,575,835 Class A Units relating to interests under the
   Holding LLC ETAs held by PIMCO MDs) and (ii) the PPGP Note Agreement (if
   outstanding) to PacMan.

7. Allianz GP Sub acquires all member interests in Holding LLC from PacMan for
   $100, becoming the sole member of Holding LLC.

8. Allianz GP Sub contributes cash and Allianz Shares to Holding LLC (now owned
   100% by Allianz GP Sub) with a total value equal to the Unit Price
   multiplied by 15,575,835 (the number of Class A Units relating to interests
   under the Holding LLC ETAs held by PIMCO MDs). Cash constitutes 84% of the
   total value and the Allianz Shares 16% of the total value, with the Allianz
   Shares valued for this purpose at $273.99 per registered share. Allianz GP
   Sub also contributes the 142,480 Class A Units acquired in Step 3 to Holding
   LLC.

9. Subject to obtaining any required consents of the respective limited
   partners of NFJ LP, Parametric LP and Cadence LP, each of such limited
   partnerships as to which required consents are obtained or as to which such
   consents are not required shall distribute to its general partners (NFJ LLC,
   PPA LLC and CCM LLC, respectively) all but one of the Class A Units in such
   limited partnerships relating to the general partner interests in such
   limited partnerships.

                                       1

   under the Holding LLC ETAs held by PIMCO MDs). Cash constitutes 84% of the
   total value and the Allianz Shares 16% of the total value, with the Allianz

   Sub also contributes the 142,480 Class A Units acquired in Step 3 to Holding
   LLC.

(the transactions described in clauses (i), (ii), (iii), (iv) and (v) of this
sentence or otherwise set forth in the Agreement, collectively, the
"Transaction"). The terms and conditions of the Transaction are set forth in
more detail in the Agreement.

   You have requested our opinion as investment bankers as to the fairness,
from a financial point of view, of (i) the Holdings LP Merger Consideration to
the holders of Holdings LP Units, other than the Excluded Holders (as defined
below), (the "Holdings Covered Units"), and (ii) the Advisors LP Merger
Consideration to the holders of Class A Advisors LP Units, other than the
Excluded Holders, (the "Advisors Covered Units"). For purposes of this opinion,
"Excluded Holders" means Pacific Life Insurance Company and each of its
affiliates (including without limitation those entities holding the Class A
Advisors LP Units that are burdened by the ETAs), Partners LLC, Partners GP and
each of the managing directors of Pacific Management Investment Company
(including without limitation any units held for the benefit of such persons).

   In connection with rendering our opinion, we have, among other things: (i)
reviewed the October 27, 1999 draft of the Agreement (including the exhibits
thereto) in the form provided to us, and have taken into account the terms of
the Transaction set forth therein, including without limitation the Pacific
Arrangements and the Management Arrangements; (ii) reviewed certain publicly
available business and financial information that we deemed relevant relating
to Holdings LP, Advisors LP and the industry in which they operate; (iii)
reviewed certain internal non-public financial and operating data and other
information provided to us by the management of Holdings LP

                                      B-2
<PAGE>

and Advisors LP relating to Holdings LP's and Advisors LP's respective
businesses, including certain forecast and projection information as to the
future financial results of such businesses; (iv) reviewed certain publicly
available business and financial information with respect to certain other
companies that we believed to be relevant or comparable in certain respects to
Holdings LP and Advisors LP, and the trading markets for such other companies'
securities; (v) reviewed and analyzed certain publicly available and other
information concerning the trading of, and the trading market for, the Holdings
LP Units; (vi) reviewed the financial terms (including without limitation
arrangements with management and controlling persons to the extent publicly
available) of certain business combinations and acquisition transactions we
deem reasonably comparable to the Transaction and otherwise relevant to our
inquiry; (vii) discussed with members of senior management and other officers,
employees and representatives of Holdings LP and Advisors LP the foregoing,
including the past and current business operations, financial condition and
prospects of Holdings LP and Advisors LP; and (viii) considered such other
information, financial studies, analyses, investigations and financial,
economic, market and trading criteria as we deemed relevant to our inquiry.

   In our review and analysis and in arriving at our opinion, we have assumed
and relied upon, without assuming any responsibility for verification, the
accuracy and completeness of all of the financial and other information
provided to, discussed with, or reviewed by or for us, or publicly available.
We also have assumed that the final form of the Agreement (including the
exhibits thereto) will not vary in any respect that is material to our analysis
from the last draft reviewed by us. With respect to Holdings LP's and Advisors
LP's financial projections provided to, discussed with or reviewed for us by
the management of Holdings LP or Advisors LP, respectively, we have been
advised by management of Holdings LP and Advisors LP, respectively, and have
assumed, that they have been reasonably prepared on bases reflecting the best
currently available estimates and judgments on the part of management of
Holdings LP or Advisors LP, respectively, as to the future financial
performance of Holdings LP or Advisors LP, as applicable. We express no view as
to such projections or information or the assumptions on which they are based.
We have not assumed any responsibility for making or obtaining any independent
evaluations or appraisals of any of the assets or liabilities of Holdings LP or
Advisors LP, nor for conducting a physical inspection of the properties and
facilities of Holdings LP or Advisors LP, and we have not been furnished with
any such evaluation or appraisal. We have relied upon counsel to Holdings LP
and Advisors LP with respect to interpretations of the provisions contained in
the constituent documents and related agreements of Holdings LP and Advisors LP
and the application of applicable law to such documents and agreements. Our
opinion necessarily is based on market, economic and other conditions as they
exist and can be evaluated on the date hereof, and we assume no responsibility
to update or revise our opinion based upon circumstances or events occurring
after the date hereof. Our opinion does not address the underlying business
decision to effect the Transaction.

   In connection with the preparation of this opinion, we have not been engaged
by Holdings LP or Advisors LP to solicit third-party indications of interest
for the acquisition of all or any part of Holdings LP or Advisors LP, and we
have not participated in the structuring of the Transaction or the negotiation
of the terms of the Agreement.

   As you are aware, Salomon Smith Barney Inc. ("SSB") has acted as a financial
advisor to Holdings LP and Advisors LP in connection with the Transaction and
will receive a fee for such services, all of which fee will be received in
connection with the delivery of this opinion. In addition, Holdings LP and
Advisors LP have agreed to indemnify us for certain liabilities arising out of
our engagement. We, in the ordinary course of business, have from time to time
provided, and in the future may continue to provide, investment banking,
financial advisory and other related services to

                                      B-3
<PAGE>

Holdings LP, Advisors LP, Allianz A.G. and/or their respective affiliates, as
the case may be, for which we have or will receive fees. In the ordinary course
of business, we or our affiliates may trade in the debt and equity securities
of Holdings LP, Allianz A.G. and/or their respective affiliates, as the case
may be, for our own accounts and for the accounts of our customers and,
accordingly, may at any time hold a long or short position in such securities.
In addition, we and our affiliates (including Citigroup Inc. and its
affiliates) may maintain business relationships with Holdings LP, Advisors LP,
Allianz A.G. and/or their respective affiliates.

   This opinion is provided for the information of Advisors LP, Holdings LP,
Partners GP, Partners LLC and Holding LLC in the evaluation of the Transaction,
and this opinion is not intended to be and does not constitute a recommendation
to any equityholder of Holdings LP, Advisors LP or Partners LLC as to how such
equityholder should vote on any matters relating to the Transaction.

   This opinion shall not be reproduced, disseminated, quoted, summarized or
referred to at any time, in any manner or for any purpose, nor shall any public
references to SSB or any of its affiliates be made by Holdings LP, Advisors LP,
Partners LLC or any of their respective affiliates, without the prior written
consent of SSB. Notwithstanding the foregoing, this opinion may be included in
its entirety or, with our prior review and consent, referred to in any proxy
statement sent to the equityholders of Holdings LP or Advisors LP with respect
to the Transaction.

   Based upon and subject to the foregoing, we are of the opinion that, as of
the date hereof, (i) the Holdings LP Merger Consideration is fair, from a
financial point of view, to the holders of Holdings Covered Units, and (ii) the
Advisors LP Merger Consideration is fair, from a financial point of view, to
the holders of Advisors Covered Units.

                                          Very truly yours,

                                          SALOMON SMITH BARNEY INC.

Project Scope

   PIMCO asked McLagan Partners to opine on the suitability of proposed
retention incentive arrangements and the payments provided for thereunder. Our
comments on the proposed retention incentive arrangements are based exclusively
on a review of:

  .  The PIMCO Advisors L.P. Retention Plan for Executives of Pacific
     Investment Management Company (dated October 25, 1999).

                                      C-1

  .  Various analyses and proposed allocations prepared by management that
     relate to the above Plan.

   Our evaluation is based on the assumption that:

  .  The primary objectives of the proposed retention incentive arrangements
     are to retain and motivate key executives and investment talent
     subsequent to Allianz's acquisition of PIMCO.

  .  The loss of PIMCO's executives and senior investment talent would have a
     materially adverse impact on PIMCO's business and investment results
     and, in turn, the Firm's total enterprise value.

  .  The retention/incentive arrangements are not intended to act as
     substitutes for ongoing base salary and bonus plans that are unrelated
     to the proposed acquisition.

  .  A five-year retention period is required to integrate PIMCO's business
     practices and processes, and the collective knowledge and expertise of
     its staff into Allianz.

McLagan Partners' Opinion

   We focused on the following in developing our Opinion on the Retention Plan
referred to above:

  .  External market practices associated with acquisition-related retention
     incentive programs within the financial services industry.

  .  Internal historical compensation practices and expected current year pay
     levels for investment talent within PIMCO.

  .  Extensive meetings with James G. Ward, Senior Vice President and
     Director of Human Resources PIMCO Advisors.

  .  Project Apostle Executive Summary dated 27 October 1999.

  .  The Pacific Investment Management Company Non-Qualified Profit Sharing
     Plan.

  .  Form of Employment Contracts for Pacific Investment Management Company
     Managing Directors.

   In terms of external market practices, we have observed the following
through our consulting work involving the design and evaluation of acquisition-
related retention plans within the financial services industry.

  .  Retention incentive program coverage is typically limited to officer-
     level staff.

  .  Targeted retention incentive award values are greatest for incumbents
     having the ability to most significantly impact future business and
     investment results.

  .  Awards are often established as a multiple of annual cash compensation
     within a tiered framework linked to organizational level. For example:

    -- For staff below executive management, retention incentive multiples
       often approximate one times annual compensation over a three-year
       period.

    -- For executive management (i.e., Managing Directors and above),
       retention incentive multiples are higher.

                                      C-2

   Award multiples for individual participants vary within this framework
based on a number of factors, including, but not limited to, relative business
impact and tenure.

  .  Retention incentive values and participation rates are generally higher
     in acquisitions driven by strategic business concerns. Correspondingly,
     such values and rates are generally lower when the acquiring firm's
     objectives are strictly focused on near-term financial returns.

  .  The timing of retention incentive payouts generally coincides with the
     anticipated time required to successfully integrate the acquired firm,
     its business practices and investment processes. and its collective
     knowledge and staff expertise

   In terms of our understanding of PIMCO's internal pay practices and levels,
we observe that:

  .  PIMCO has covered its senior staff under several highly structured
     incentive arrangements that are directly linked to PIMCO's profits.

  .  Based on past, current, and projected profits. PIMCO's incentive plans
     have generated significant compensation, in aggregate and for selected
     senior executives.

   We are of the opinion that the proposed retention incentive arrangements
referenced herein are reasonable in light of competitive market practices and,
moreover, PIMCO's existing pay practices and levels. Further we are of the
opinion that the retention incentive arrangements referenced herein are
suitable to Allianz's presumed objectives of retaining and motivating PIMCO's
officers in the context of the contemplated acquisition by Allianz.

Cordially,

s/ Michael P. Curran
