ITEM 1. BUSINESS
 
OVERVIEW
 
  PIMCO Advisors Holdings L.P. ("PIMCO Holdings") is a Delaware limited
partnership which as its sole business holds approximately 46 million general
partnership units of PIMCO Advisors L.P. ("PIMCO Advisors"), representing an
approximate 43% equity interest in PIMCO Advisors. PIMCO Partners, G.P.
("PGP") is the sole general partner of PIMCO Holdings and is the controlling
general partner of PIMCO Advisors.
 
  PIMCO Advisors is one of the largest investment management firms in the U.S.
with approximately $200 billion under management at December 31, 1997. PIMCO
Advisors' business provides high quality fixed income and equity investment
management to institutional and retail clients, offering the investment
management expertise, performance record and reputations of its institutional
investment managers, which include the fixed income oriented Pacific
Investment Management Company ("Pacific Investment Management") and the equity
oriented Oppenheimer Capital. PIMCO Advisors' business focuses on:
 
  Institutional Fixed Income. PIMCO Advisors provides fixed income investment
management to large and medium-sized foreign and domestic corporate and public
clients, including 59 of the largest 200 U.S. pension funds. Fixed income
management is led by Pacific Investment Management, which offers impressive
long-term performance records across a diverse range of product offerings such
as total return, international and other duration or sector specific
strategies.
 
  Institutional Equity. PIMCO Advisors provides equity investment management
to institutional clients offering the investment management expertise of six
equity management groups, including the highly regarded Oppenheimer Capital.
PIMCO Advisors offers investors an enhanced index based strategy and a variety
of management styles, including value, growth, modified growth, quantitative
and international.
 
  Institutional clients invest through separate accounts and pooled vehicles
such as the institutional share classes of the PIMCO Funds, PIMCO Advisors'
family of 45 proprietary mutual funds. PIMCO Advisors offers its investment
management services to institutional clients through client service
representatives at each of its investment managers.
 
  Retail Distribution. PIMCO Advisors offers the investment expertise of its
institutional investment managers to retail investors through the retail share
classes of the PIMCO Funds. They are distributed primarily through broker-
dealers including PIMCO Funds Distributors LLC ("PFD", formerly known as PIMCO
Funds Distribution Company), a wholly-owned broker-dealer which distributes
and markets shares of the retail mutual funds of PIMCO Advisors. In addition,
PIMCO Advisors offers retail investors wrap fee accounts, variable annuity
products, 401(k) programs and various investment products through sponsored
trust companies.
 
  PIMCO Advisors' strategy is to increase the amount and diversification of
its assets under management through (i) growth in the institutional market
through providing high levels of client service and entering new
 
                                       1
<PAGE>
 
markets in the United States and overseas, (ii) growth in the retail market by
building brand awareness and direct marketing of the PIMCO Funds through its
broker-dealer network and through penetrating additional distribution channels
and (iii) new product offerings to institutions and retail investors.
 
  The revenues of PIMCO Advisors consist principally of management fees based
on the value of assets under management and, in some cases, the performance of
the advisor. The following table sets forth the growth and composition of
PIMCO Advisors' assets under management over the last three years (as adjusted
to include the assets under management of Oppenheimer Capital):

INVESTMENT PRODUCTS
 
  PIMCO Advisors provides fixed income investment management to large and
medium-sized foreign and domestic corporate and public clients, including 59
of the largest 200 U.S. pension funds, offering impressive long-term
performance records across a diverse range of product offerings such as total
return, low duration and other duration or sector specific strategies. PIMCO
Advisors also provides equity investment management to institutional and
retail clients, offering investors a variety of management styles, including
value, growth, balanced and quantitative management styles, as well as an
enhanced equity based strategy.
 
 Fixed Income Management
 
  Primarily through Pacific Investment Management, PIMCO Advisors offers a
variety of strategies for clients with fixed income portfolios, designed to
reflect each particular client's investment objective. PIMCO Advisors believes
that its strength in the management of fixed income assets is derived from
Pacific Investment Management's investment philosophy, which stresses a long-
term or secular focus, active management, with measured risk taking, and the
application of strong analytical capabilities across all fixed income market
sectors. Under this philosophy, longer term macro-economic trends are key
inputs to portfolio strategy, and moderate portfolio duration ranges are
favored to reduce volatility relative to client-specified benchmarks. Pacific
Investment Management's investment strategy begins with an intensive review of
long-term and cyclical trends to anticipate interest rates, volatility, yield
curve shape and credit trends. These forecasts become the basis for the major
portfolio strategies. Pacific Investment Management then uses a quantitative
valuation framework to select specific portfolio investments. Fixed income
products include:
 
  Total Return Portfolios. Total return portfolios are structured with the
objective of realizing maximum total return, consistent with the preservation
of capital and prudent investment management across the spectrum of fixed
income securities. This strategy generally results in a portfolio duration of
three to six years. Portfolios utilizing this strategy represented
approximately $71.7 billion of Pacific Investment Management's total assets
under management at December 31, 1997.
 
                                       2
<PAGE>
 
  Low Duration Portfolios. Pacific Investment Management has actively managed
low duration accounts since 1979 (overall portfolio duration one to three
years). The objectives in the low duration portfolios are to preserve
principal through investment in low-volatility instruments, while seeking to
achieve superior risk adjusted returns.
 
  Other Duration Specific or Sector Specific Portfolios. Pacific Investment
Management also offers clients active management of portfolios based upon
specific duration targets (e.g., long duration portfolios or synthetic
guaranteed investment contracts) and sector emphases (e.g., international,
high-yield, or mortgages).
 
  International and Other Portfolios. Pacific Investment Management, as
investment advisor to a series of offshore funds and separate accounts,
provides fixed income investment advice to non-U.S. investors. Assets under
management for these offshore funds totaled $6.5 billion at December 31, 1997.
Pacific Investment Management also serves as subadvisor for a series of term
trusts investing in mortgage related securities that are marketed to Japanese
investors. These trusts had assets of $2.5 billion at December 31, 1997.
Pacific Investment Management also serves as subadvisor for nine families of
U.S. mutual funds sponsored by other mutual fund complexes. Total assets under
management for these nonaffiliated funds at December 31, 1997 was $6.6
billion.
 
 Equity Management
 
  PIMCO Advisors offers clients a wide array of equity investment strategies
and products. PIMCO Advisors' investment professionals offer Value, Growth,
Modified Growth, Quantitative and International management styles, as well as
an enhanced index based strategy.
 
  Value. PIMCO Advisors offers equity clients the highly respected investment
management professionals of Oppenheimer Capital, which seeks to adhere to a
disciplined, value-oriented investment philosophy, by identifying company-
specific, rather than industry-specific opportunities. By investing in quality
securities that are temporarily out of favor or have been overlooked,
Oppenheimer Capital seeks to preserve capital in falling markets, reduce
volatility compared to the overall market and produce superior returns. In
addition, PIMCO Advisors' NFJ Investment Group follows a disciplined value
oriented approach, specializing in investing in a combination of low P/E
stocks with high dividends selected through a proprietary screening model. At
December 31, 1997, $63.8 billion of PIMCO Advisors' assets under management
were advised by value oriented investment managers, with $61.4 billion advised
by Oppenheimer Capital. Value oriented investment products include large-cap,
mid-cap and small-cap portfolios and non-U.S. and global value portfolios.
 
  Growth. PIMCO Advisors' Columbus Circle Investors follows an investment
philosophy based on the premise that companies producing results which exceed
the expectations of investors and Wall Street equity research analysts will
have rising stock prices, while companies with disappointing results will
experience stock price declines. This investment discipline focuses on the
potential for "positive momentum & positive surprise." The investment
professionals in this group monitor numerous factors, including political and
economic developments, secular trends, industry and group dynamics and
company-specific events, to determine which companies are best-positioned to
achieve revenue and earnings acceleration. Assets managed under this
investment style principally consist of large cap portfolios, but also include
small-cap, mid-cap, and equity income portfolios.
 
  Modified Growth. PIMCO Advisors' Cadence Capital Management offers a "growth
at a reasonable price" equity investment philosophy. This investment
management group's philosophy is to participate in the long-term growth of the
equity markets by constructing fully invested portfolios of stocks selling at
reasonable valuations in relation to the fundamental prospects of the
underlying companies. The group uses a disciplined, "bottom-up" investment
process which utilizes quantitative screening for favorable fundamental and
valuation attributes, followed by "hands-on" qualitative research to confirm
the apparent business trends. These managers structure their portfolios to be
broadly based, typically including 80 to 100 issues. This investment strategy
involves the application of a proprietary investment management process to
different universes of equity securities which are usually differentiated by
market capitalization into four categories: large-cap, mid-cap, small-cap and
micro-cap.
 
                                       3
<PAGE>
 
  Quantitative. PIMCO Advisors offers active and indexed strategies which are
structured to meet client specific risk and return objectives. Active
portfolios seek superior returns relative to an assigned benchmark within a
risk controlled framework, while indexed portfolios are constructed to closely
track an appropriate index. In addition, the managers manage tax efficient
separate account strategies for taxable investors. The group uses quantitative
techniques in portfolio construction and management. The active portfolios are
designed to maintain economic sector allocations similar to the benchmark.
Security selection is based on a ranking system which evaluates each stock's
exposure to valuation, earnings and momentum factors. Portfolios are optimized
to achieve a diversified group of securities which have exposure to factors
associated with superior return and risk characteristics. The group manages a
wide variety of index funds which extend to both large and small
capitalizations and across value and growth styles. The international
assignments include allocations to developed countries and emerging markets.
 
  StocksPLUS(R). In addition to its fixed income products, Pacific Investment
Management also manages an enhanced index based strategy, StocksPLUS, which
accounted for $12.0 billion of assets under management at December 31, 1997.
StocksPLUS represents a proprietary technique developed by Pacific Investment
Management that combines the active management of stock index futures (to
provide a proxy for equity market returns) with active management of a short-
term fixed income portfolio using much of the same analytics as is used by
Pacific Investment Management in its fixed income portfolios.
 
  International. PIMCO Advisors' investment management groups, including
Oppenheimer Capital and Columbus Circle Investors, offer international equity
investment products that combine country selection strategies with the
systematic application of investment processes. These include the application
of fundamental valuation criteria to country allocations and then to stock
selection in order to enhance client returns over time.
 
MARKETS AND DISTRIBUTION CHANNELS
 
 Institutional Investors
 
  The Institutional Market. The institutional market for investment management
services includes corporate, government and multi-employer pension plans,
charitable endowments and foundations, and corporations purchasing investment
management services for their own account. The industry consists of two
primary institutional markets. The defined benefit pension plan market,
historically the largest component and primary market for investment managers,
is large, fragmented, performance sensitive and generally sophisticated. The
other principal component is the defined contribution plan market, consisting
of plans such as 401(k) plans which, while historically a smaller market, has
grown in the last decade to almost equal the defined benefit market in size.
 
  At year end 1996, total U.S. pension and retirement assets were estimated at
approximately $7 trillion. Of that amount, corporate defined benefit plans
accounted for $1.5 trillion, growing at an average rate of 6.2% over the past
five years, and corporate defined contribution plans accounted for $1.4
trillion, growing at an average rate of 10.5% over the past five years. Other
sectors include insured assets (primarily group and other annuities) at $1.2
trillion, state and local government pension assets at $1.4 trillion, federal
government pension assets at $390 billion and IRA assets at $1.3 trillion.
While all sectors experienced significant growth in assets under management
during the period, the cash flow growth rate has been negative for defined
benefit plans, at (4.0%) per year during the period, while defined
contribution plans have seen positive cash inflows of 1.3% per year during the
period.
 
  Distribution and Marketing. Each of PIMCO Advisors' investment management
groups serves the institutional market and conducts institutional marketing
activities directly. In general, each investment management group conducts its
own marketing, which generally targets Fortune 1,000 companies and other large
institutional investors. The investment managers seek to develop client
relationships through investment management performance and focused,
responsive client service. Business strategies also involve increasing assets
under management for non-U.S. clients, expanding the array of fixed income and
equity products offered
 
                                       4
<PAGE>
 
to clients, seeking to expand market share with medium and smaller
institutional investors by offering pooled investment vehicles such as the
PIMCO Funds, and otherwise seeking to diversify and expand their businesses by
investment strategy, method of delivery and markets.
 
  A principal component of PIMCO Advisors' marketing strategy is the
historical performance of its investment managers relative to benchmarks over
longer periods of time. For example, Pacific Investment Management stresses
its record in equaling or exceeding client-selected performance benchmarks
over long periods through a measured risk taking approach that emphasizes
preservation of capital and focus on total return. Over the last 5 years,
Pacific Investment Management's Total Return Full Authority composite,
representing approximately 24% of Pacific Investment Management's total assets
under management at December 31, 1997, outperformed the Lehman Brothers
Aggregate Bond Index by approximately 181 basis points (9.29% compared to
7.48%) annually on a compound basis, before fees. Oppenheimer Capital has
achieved a total return of 20.5% on its large cap value composite over the
last five years, which exceeds the benchmark S&P 500 index by 22 basis points
annually on a compound basis, before fees.
 
 Retail Investors
 
  The Retail Market. Like the institutional market for investment management
services, the mutual fund market has expanded rapidly in recent years. The
retail market is served in large part through mutual funds. The mutual fund
industry is highly competitive and is characterized by a high degree of
fragmentation and a large and rapidly increasing number of product offerings.
Marketing strategies, product development, business development, sales
expertise and servicing are increasingly important. The traditional channel
for the distribution of mutual funds (other than money market funds) is
through brokerage firms that are not affiliated with the funds' sponsor
organization and that are compensated primarily through front-end sales loads
deducted from the purchaser's investment at the time of the sale. Increasingly
other distribution arrangements and channels have become important. These
include "no-load" or "low-load" funds sold primarily through direct marketing
efforts or captive sales forces affiliated with the sponsor organization;
"private label" and "proprietary" funds managed by and offered primarily
through, or to customers of, a financial organization such as a brokerage
firm, insurance company or bank; and "back-end load" or "level load" funds
offered through brokerage and other third-party channels, but with
compensation to the selling brokers being funded through commission advances
from the funds' sponsor which are recovered through ongoing charges against
fund assets assessed under Rule 12b-1 under the Investment Company Act of
1940, as amended, contingent deferred sales charges assessed against
shareholders at the time they redeem their investments, or a combination of
such sources.
 
  The PIMCO Funds. PIMCO Advisors and its investment management professionals
sponsor and manage the PIMCO Funds, a family of 45 mutual funds for both
institutional and retail investors. In January 1997, PIMCO Advisors
restructured its proprietary mutual funds into a single fund family called
"PIMCO Funds" which is comprised of 24 funds advised by Pacific Investment
Management, and 21 funds advised by PIMCO Advisors and subadvised by PIMCO
Advisors' other investment managers and one independent subadvisor. PIMCO
Funds are offered in up to five different share classes: institutional and
administrative share classes for institutional investors and, for retail
investors, Class A shares (which are "front end" load), Class B shares (which
are "back-end load"), and Class C shares (which are "level load"). The PIMCO
Funds now feature a "unified fee" structure which has specified advisory and
administrative fees per fund. As a result, PIMCO Advisors and Pacific
Investment Management (and not the PIMCO Funds) bear the risk of increases in
service costs (including third-party service providers such as transfer
agents) and will directly benefit from decreases in those costs.
 
                                       5
<PAGE>
 
  At December 31, 1997, PIMCO Funds had $29.9 billion under management, of
which $7.0 billion was represented by retail share classes. At February 28,
1998, sixteen of the PIMCO Funds had overall Morningstar ratings of 4 stars or
above. Set forth below is information regarding these funds:

(1) Rating based on institutional class shares, as Class A, B and C shares
    were initially offered on January 17, 1997. Institutional class shares
    generally have a $5 million minimum investment. Had Class A, B and C
    shares been in existence for the same period as the institutional class
    shares they may have received different ratings due to Class A, B and C
    shares' higher expense ratios and sales charges.
 
  The above chart is based on February 28, 1998 Morningstar ratings. Overall
rating is a weighted average of the fund's 3, 5 and 10-year ratings (when
applicable). During those periods there were 2,402, 1,363 and 706  domestic
equity funds; 717, 306 and 107 international equity funds; 1,400, 826 and 335
taxable bond funds; and 1,502, 775 and 347 municipal bond funds rated,
respectively. Morningstar ratings reflect historical risk-adjusted performance
and are subject to monthly changes. Therefore, past ratings are not a
guarantee of future results. The ratings are calculated from a fund's average
annual total return with the appropriate sales charge adjustment and a risk
factor that reflects fund performance relative to three-month Treasury bill
returns. 5-star ratings are limited to the top 10% of funds in an investment
category, the next 22.5% earn 4 stars, the next 35% earn 3 stars, the next
22.5% earn 2 stars and the bottom 10% earn 1 star. Morningstar ratings are
based on a fund's oldest class of shares.
 
  PFD, a wholly-owned subsidiary of PIMCO Advisors, is the distributor for the
PIMCO Funds. PIMCO Advisors uses PFD to distribute the retail share classes of
PIMCO Funds through a large, diversified network of unaffiliated retail
broker-dealers, including many leading full-service broker-dealers. PFD has
selling agreements with over 1,000 broker-dealers and banks. The sales and
marketing personnel develop and support sales and marketing strategies between
PIMCO Advisors and individual retail broker-dealers. Additionally, the
relationships fostered by this group allow PFD's wholesalers to have access to
the branch offices and sales representatives of the retail broker-dealers.
 
  Other Aggregators and Intermediaries. PIMCO Advisors' strategy also involves
focusing on financial service aggregators of retail assets such as
unaffiliated sponsors of mutual funds and other registered investment advisors
(including fee-based financial planners) who recommend the use of "no-load"
mutual funds such as the institutional and administrative fee-only classes of
PIMCO Funds to their clients, and consultant alliances.

  In addition to the 45 PIMCO Funds, PIMCO Advisors' investment managers
subadvise third-party sponsored mutual funds. In particular, Opcap Advisors, a
subsidiary of Oppenheimer Capital, serves as subadvisor for six funds in the
Quest Series of OppenheimerFunds having $6.6 billion under management at
December 31, 1997. The Class A shares of five of these funds had overall
Morningstar ratings of four stars, based on February 28, 1998 Morningstar
ratings.
 
  Wrap Fee Accounts. Oppenheimer Capital has become actively involved in
managing wrap fee accounts, or broker-sponsored asset management programs.
Wrap fee accounts have grown rapidly since their introduction, reaching nearly
$8.0 billion under management at December 31, 1997. Oppenheimer Capital's
success is attributable in large part to its strong long term track record
which brokers promote in marketing.
 
  Through wrap fee programs, brokers offer their clients discretionary
portfolio management services. The services are provided through independent
investment managers selected by the broker and the client from the broker's
approved list of managers. The broker's client investment objectives are
analyzed and an investment manager is chosen whose investment philosophy
appears to be compatible with the client's goals. The client enters into an
investment advisory agreement with the broker which has a separate master
agreement with Oppenheimer Capital. The client pays a single, all-inclusive
fee which covers investment advisory services rendered, as well as custodial,
execution and other client-related services performed by the broker, exclusive
of exchange fees and transfer taxes mandated by law. The broker pays
Oppenheimer Capital a fee monthly or quarterly, from the all-inclusive fee
collected from the client. Oppenheimer Capital serves as wrap account manager
for 15 programs totalling $8.0 billion under management, with approximately
70% of those assets originated through the Salomon Smith Barney brokerage
network.
 
  Variable Annuities. Oppenheimer Capital has developed a program managing
funds which support the variable annuity products of a number of insurance
companies. Since introduction, this program has grown to nearly $4.3 billion
in assets under management at December 31, 1997.
 
  Asset growth is being driven by a combination of market appreciation,
investment performance and the development of relationships with additional
insurance companies. Oppenheimer Capital's largest fund supporting variable
annuities is the Enterprise Accumulation Trust, offered by the Mutual Life
Insurance Company of New York. The OCC Accumulation Trust is offered by twelve
insurance companies in support of their variable annuity products. Oppenheimer
Capital also manages portfolios for the variable annuity accounts of four
other insurance companies and is developing investment advisory relationships
with additional insurance companies to manage assets for both variable annuity
and variable life insurance products.
 
GROWTH STRATEGY
 
  PIMCO Advisors' strategy is to increase the amount and diversification of
its assets under management through (i) growth in the institutional market by
providing high levels of client service and entering new markets in the United
States and overseas, (ii) growth in the retail market by building brand
awareness and direct marketing of the PIMCO Funds through its broker-dealer
network and through penetrating additional distribution channels and (iii) new
product offerings to institutions and retail investors. PIMCO Advisors'
initiatives include:
 
  Continued Institutional Growth. PIMCO Advisors works to build on the
strength of its institutional client base by providing high levels of client
service, penetration of new markets and new product offerings. In particular,
PIMCO Advisors is seeking to increase assets managed for overseas
institutional investors, and has recently established or expanded offices in
London, Tokyo, Singapore and Sydney. In addition, PIMCO Advisors formed a
Dublin trust as an additional vehicle for pooled investment by foreign
institutions and high net worth individuals.
 
  Retail Base Expansion. PIMCO Advisors has commenced a significant initiative
to build its retail distribution through investing in its broker-dealer
network, increasing its participation in mutual fund "supermarkets", expanding
its presence in the 401(k) market by increasing the number of plan sponsors
offering PIMCO Advisors' investment products and building brand awareness both
at the broker-dealer level and the
 
                                       7
<PAGE>
 
retail investor level through increased marketing and public relations
initiatives. In addition, PIMCO Advisors seeks growth through building on its
success in wrap fee accounts, variable annuity programs and sponsored trust
companies offering retail investment products.
 
  New Product Offerings. PIMCO Advisors pursues growth in both the
institutional and retail markets through offering new products. By assessing
current product offerings, working with clients and monitoring market trends,
PIMCO Advisors identifies areas for new product placement. Leveraging off the
depth and expertise of its investment professionals, PIMCO Advisors has
recently developed several new funds to enhance its product line and expects
to continue to supplement its fund offerings. Recent new product offerings
include investments in international bonds and a "real return" fund, investing
in inflation indexed bonds.
 
  PIMCO Advisors pursues these strategies both through internal investment and
through targeting existing investment managers and selectively acquiring those
that have demonstrated strong investment performance or provide complementary
products and investment philosophies to PIMCO Advisors' existing investment
management groups.
 
RECENT DEVELOPMENTS
 
  Opgroup Transaction. On November 4, 1997, PIMCO Advisors acquired
Oppenheimer Group, Inc. ("Opgroup"), which owned through a subsidiary the
32.4% managing general partner interest in Oppenheimer Capital, a one percent
general partner interest in PIMCO Holdings, one percent general partner
interests in three subsidiaries of Oppenheimer Capital and 100% of Value
Advisors LLC, a newly formed limited liability company holding eight closed-
end investment fund management contracts formerly held by Advantage Advisers,
Inc. (the "Opgroup Acquisition"). In the transaction, Opgroup became a
subsidiary of PIMCO Advisors, and the Opgroup stockholders received 2.1
million PIMCO Advisors Class A units and rights to exchange up to $230 million
of outstanding term notes of Opgroup for an additional 6.9 million PIMCO
Advisors Class A units at $33 1/3 per unit. Following the merger, Opgroup
caused its investment advisory assets to be contributed to PIMCO Advisors in
exchange for PIMCO Advisors Class C units. See "Certain Relationships and
Transactions: Contribution Agreement." In connection with the transaction,
PIMCO Advisors split the one percent general partner interest in PIMCO
Holdings into a .01% general partner interest and a .99% limited partner
interest, and sold the general partner interest to its general partner for
$80,000.
 
  OpCap Merger. On November 30, 1997, Oppenheimer Capital merged with a
subsidiary of PIMCO Advisors, with Oppenheimer Capital surviving (the "OpCap
Merger"). In the OpCap Merger, PIMCO Advisors acquired from PIMCO Holdings its
67.6% general partner interest in Oppenheimer Capital in exchange for
25.5 million PIMCO Advisors Class A units. Concurrent with the merger, PIMCO
Holdings acquired an additional 0.6 million PIMCO Advisors Class A units for
$16.7 million in cash. As a result, Oppenheimer Capital became a wholly-owned
subsidiary of PIMCO Advisors and the limited partner units of PIMCO Holdings
came to represent an indirect investment in the business of PIMCO Advisors. On
December 1, 1997, PIMCO Holdings effected a 1.67 for 1 split of the PIMCO
Holdings units, so that each PIMCO Holdings unit outstanding after the split
represented an economic interest in one PIMCO Advisors unit.
 
  Public Ownership Restructuring. On December 31, 1997, the publicly held
limited partner interests of PIMCO Advisors and PIMCO Holdings were
consolidated through an exchange of publicly traded PIMCO Advisors units for
an equal number of PIMCO Holdings units. In addition, PIMCO Holdings changed
its name from Oppenheimer Capital, L.P. to PIMCO Advisors Holdings L.P., and
PIMCO Holdings units, which continued to be traded on the New York Stock
Exchange, became traded under the symbol "PA." As a result, all direct and
indirect public ownership interests in the business of PIMCO Advisors were
consolidated into one entity. In addition, PIMCO Advisors ceased to be
publicly traded, allowing it to become a private partnership not subject to
the tax on the gross income from active businesses of publicly traded
partnerships which became effective after December 31, 1997.
 
  Change in Fiscal Year. Prior to the Opcap Merger, PIMCO Holdings reported
its results of operations and its financial position based on an April 30
fiscal year end. Upon completion of the Opcap Merger, PIMCO Holdings changed
its fiscal year to a calendar year to correspond with that of PIMCO Advisors.

COMPETITION
 
  The investment management business is highly competitive. PIMCO Advisors
competes with a large number of other domestic and foreign investment
management firms, commercial banks, insurance companies, broker-dealers and
other financial services providers. Some of these financial services companies
have greater resources, assets under management and administration than PIMCO
Advisors and offer a broader array of investment products and services.
 
  PIMCO Advisors believes that the most important factors affecting its
success are the abilities, performance records and reputations of its
investment managers, and the development of new investment and marketing
strategies. The relative importance of these factors varies depending on the
type of investment management service involved. Client service is also an
important competitive factor. PIMCO Advisors' ability to increase and retain
client assets could be adversely affected if client accounts underperform the
market over time or if key investment managers leave the firms. The ability of
PIMCO Advisors to compete with other investment management firms is also
dependent, in part, on the relative attractiveness of their investment
philosophies and methods under prevailing market conditions. There are
relatively few barriers to entry by new investment management firms in the
institutional managed accounts business, which increases competitive pressure.
 
  A large number of mutual funds are sold to the public by investment
management firms, broker-dealers, insurance companies and banks in competition
with mutual funds sponsored by PIMCO Advisors. Many competitors apply
substantial resources to advertising and marketing their mutual funds which
may adversely affect the ability of PIMCO Advisors-sponsored funds to attract
new retail clients and to retain retail assets under management.
 
FEE REVENUES
 
 General Characteristics
 
  Investment management agreements between PIMCO Advisors' investment
management groups and their clients typically provide for fees based on a
percentage of the assets under management, generally determined at least
quarterly and valued at current market levels. The percentage of the fee
applicable to a particular classification of assets under management is a
function of several factors. For example, investments or strategies which have
a higher degree of risk and uncertainty command a higher percentage fee.
Therefore, significant fluctuations in securities prices or in the investment
patterns of clients that result in shifts in assets under management can have
a material effect on PIMCO Advisors consolidated revenues and profitability.
Such fluctuations in asset valuations and client investment patterns may be
affected by overall economic conditions and other factors influencing the
capital markets and the net sales of mutual fund shares generally, including
interest rate fluctuations. Virtually all of PIMCO Advisors' revenues are
derived from investment management agreements with clients that are terminable
at any time or upon 30 to 60 days' notice, as is the case generally in the
investment management industry. Any termination of agreements representing a
significant portion of assets under management could have an adverse impact on
PIMCO Advisors' results of operations. The investment management business is
highly competitive and fees vary among investment managers. Some of PIMCO
Advisors' investment management groups' fees are higher than those of many
investment managers relative to the average size of accounts under management.
Each investment manager's ability to maintain its fee structure in the
competitive environment is dependent to a large extent on the ability of its
investment managers to provide clients with service and investment returns
that will cause clients to be willing to pay those fees. There can be no
assurance that PIMCO Advisors' investment management groups will be able to
retain their clients or sustain their fee structures in the future.
 
 Performance-Based Fees
 
  Approximately 4.6%, 4.0% and 4.0% of PIMCO Advisors' revenues (as adjusted
to combine with the revenues of Oppenheimer Capital) for the years ended
December 31, 1997, 1996 and 1995, respectively, were
 
                                       9
<PAGE>
 
derived from performance-based fees. Most of these revenues are attributable
to Pacific Investment Management's operations. To earn a performance-based fee
with respect to an account, the relevant investment manager must generally
outperform a specific benchmark over a particular period. Performance-based
fee arrangements make revenues more volatile, but also provide an opportunity
to earn higher fees than could be obtained under fee arrangements based solely
on a percentage of assets under management. Pacific Investment Management's
StocksPLUS product, which accounted for $12.0 billion of assets under
management at December 31, 1997, is generally subject to a performance-based
arrangement in which under-performance relative to the S&P 500 over a
particular time period results in no fees being paid by clients, while
superior performance results in incentive fees that are generally not subject
to a cap. In addition to the StocksPLUS accounts, several large fixed income
accounts aggregating approximately $11.3 billion at December 31, 1997, also
have performance-based fee arrangements. Pacific Investment Management's
performance-based fee arrangements, including the StocksPLUS fee arrangement,
can materially affect Pacific Investment Management's revenues, and thus those
of PIMCO Advisors, from period to period.
 
ITEM 2. PROPERTIES
 
  The principal offices of PIMCO Holdings and PIMCO Advisors are located at
(i) 800 Newport Center Drive, Newport Beach, California where they soon will
occupy approximately 15,000 square feet of space under a lease expiring in
2005 and (ii) 2187 Atlantic Street, Stanford, Connecticut where PIMCO Advisors
and PFD occupy approximately 17,200 square feet of space under a sublease
expiring in 2002. Pacific Investment Management's principal offices are
located at 800 and 840 Newport Center Drive and 5 Civic Plaza, Newport Beach,
California where it occupies approximately 85,000 square feet of space under
leases expiring in 1998 and 2005. Oppenheimer Capital currently maintains
office space at the following locations: approximately 40,000 square feet at
the Oppenheimer Tower, New York, New York; 39,800 square feet at the Merrill
Lynch Tower, New York, New York; and 44,000 square feet at 33 Maiden Lane, New
York, New York. Each location is a modern office building and the space is
adequate for PIMCO Holdings' and PIMCO Advisors' current operations, but more
space may be necessary should PIMCO Advisors business expand.
 
ITEM 3. LEGAL PROCEEDINGS
 
  On November 10, 1997, Richard Buzby filed an action on behalf of a purported
class of limited partners of PIMCO Holdings against PIMCO Advisors and certain
individuals associated with the previous general partner of PIMCO Holdings in
the Court of Chancery of the State of Delaware, New Castle County. The
complaint alleges, among other things, various breaches of fiduciary duty,
conflicts of interest and unfair dealing in connection with the Oppenheimer
Capital Merger. The complaint seeks compensatory and/or rescissionary money
damages or, alternatively, injunctive relief or rescission of the
transactions. After that date, certain other complaints were filed in the
states of Delaware and New York, making similar allegations.
 
  On December 17, 1997, PIMCO Advisors and PIMCO Holdings issued a press
release announcing that they reached an agreement to settle the various class
action lawsuits filed against them and other defendants in connection with the
Oppenheimer Capital Merger. As part of the settlement, the class will receive
$1 per PIMCO Holdings unit for each of the 15.4 million PIMCO Holdings units
outstanding for holders of record as of November 4, 1997, payable as a
distribution after reduction for court-awarded attorney's fees and costs.
PIMCO Advisors and PIMCO Holdings reported that the $15.4 million provides
material value to the members of the class. The settlement was recorded as
part of the purchase price and the resulting intangibles will be amortized
over 20 years and thus, PIMCO Advisors and PIMCO Holdings believe, will have
no material effect on earnings or distributions. The settlement is subject to
court approval.
 
  Except as described above, there are no material legal proceedings pending
or, to the knowledge of management, threatened against PIMCO Holdings or PIMCO
Advisors.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
 
  Until December 31, 1997, PIMCO Holdings units (formerly Oppenheimer Capital,
L.P. units) were traded on the NYSE under the symbol "OCC" and the PIMCO
Advisors Class A limited partner units were traded on the NYSE under the
symbol "PA." Commencing January 1, 1998, following the combination of the
public ownership of PIMCO Holdings and PIMCO Advisors, the PIMCO Advisors
Class A units are no longer publicly traded and PIMCO Holdings units are
traded on the NYSE under the symbol "PA."
 
  The following table sets forth, for the periods indicated, the high and low
trading prices for PIMCO Holdings units as reported on the NYSE and the total
cash distributions paid per PIMCO Holdings unit:

(1) On December 1, 1997, PIMCO Holdings changed its fiscal year end to
    December 31. The information displayed in this chart through December 31,
    1997 is based on a fiscal year end of April 30.
(2) PIMCO Holdings unit prices and distributions prior to December 1, 1997
    have been restated to reflect the 1.67-to-one unit split effective as of

  On March 23, 1998, the closing price of PIMCO Holdings units was $34.125 per
unit and there were approximately 2,015 holders of record of PIMCO Holdings
units.

DISTRIBUTION POLICY
 
  PIMCO Holdings' policy is to distribute substantially all of its net cash
flow on an annual basis. Distributions are declared and paid to unitholders of
record within thirty days following the end of each calendar quarter on March
31, June 30, September 30 and December 31 of each year. Because PIMCO
Holdings' sole business is to hold an investment as a general partner of PIMCO
Advisors, the cash flow of PIMCO Holdings consists of distributions from PIMCO
Advisors. The Amended and Restated Agreement of Limited Partnership of PIMCO
Advisors Holdings L.P., as amended (the "PIMCO Holdings Partnership
Agreement") requires the general partner of PIMCO Holdings to declare
quarterly distributions to the record holders of PIMCO Holdings units (the
"Unitholders") in an amount equal to the cash distributions from PIMCO
Advisors, less expenses and reserves. Because PIMCO Advisors currently pays
all expenses of PIMCO Holdings other than taxes, PIMCO Holdings' per-unit
distributions generally equal the PIMCO Advisors distributions less applicable
taxes.
 
  PIMCO Advisors distributes on an annual basis cash in an amount equal to
Operating Profit Available for Distribution (as defined in the Amended and
Restated Agreement of Limited Partnership of PIMCO Advisors L.P. (the "PIMCO
Advisors Partnership Agreement")) less any amount deemed required for capital
expenditures, future payments of indebtedness, as reserves or otherwise in the
business of PIMCO Advisors. In general, the Management Board of PIMCO Advisors
evaluates distribution levels late in the fourth quarter of each year based on
expected year end earnings and the anticipated earnings for the ensuing year.
The Management Board of PIMCO Advisors has set a quarterly distribution rate
of $0.60 per PIMCO Advisors unit for the first three calendar quarters of
1998, which equates to a distribution rate at PIMCO Holdings (after taxes at
PIMCO Holdings) of $0.53 per unit.
 
  Actual distribution levels will depend on the financial performance of PIMCO
Advisors, and there can be no assurance that the stated distribution rates
will be achieved. Distributions made by PIMCO Holdings will depend on the
profitability of the investment management business of PIMCO Advisors, which
is affected in part by overall economic conditions and other factors affecting
capital markets generally, which are beyond the control of PIMCO Holdings and
PIMCO Advisors. In addition, the general partners of PIMCO Advisors may, in
determining the amount of distributions, deduct any amount from Operating
Profit Available for Distribution the general partners deem may be required
for capital expenditures, reserves or otherwise in the business of PIMCO
Advisors. To the extent PIMCO Advisors or PIMCO Holdings retains profits in
any year, unitholders may have taxable income from PIMCO Holdings that exceeds
their cash distributions.
 
ITEM 6. SELECTED CONSOLIDATED FINANCIAL DATA
 
  The following tables set forth summary financial data of PIMCO Holdings
(retroactively restated to reflect a 1.67 for 1 unit split effective December
1, 1997) and Oppenheimer Capital for the eight months ended December 31, 1997,
and each of the five years ended April 30, 1997 and selected consolidated
financial data of PIMCO Advisors for each of the five years ended December 31,
1997. In the fourth quarter of 1997, PIMCO Advisors acquired Oppenheimer
Capital, and PIMCO Holdings investment in Oppenheimer Capital was exchanged
for an interest in PIMCO Advisors. Accordingly, PIMCO Advisors data includes
the performance of Oppenheimer Capital from November 4, 1997, and PIMCO
Holdings data consists of the performance of PIMCO Advisors from December 1,
1997. In addition, PIMCO Advisors and its subsidiaries were formed on November
15, 1994, when Pacific Asset Management LLC merged certain of its investment
management businesses and substantially all of its assets (the "PFAMCo 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 PFAMCo Group. Therefore, the historical
financial statements of PIMCO Advisors include the operations of PFAMCo 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 PIMCO Advisors Holdings L.P., the consolidated
financial statements of PIMCO Advisors L.P. and the consolidated financial
statements of Oppenheimer Capital, and the related notes thereto included
elsewhere in this report on Form 10K and "Management's Discussion and Analysis
of Financial Condition and Results of Operations of PIMCO Advisors Holdings
L.P."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
      RESULTS OF OPERATIONS OF PIMCO ADVISORS HOLDINGS L.P.
 
GENERAL
 
  PIMCO Advisors Holdings L.P. ("PIMCO Holdings") (formerly Oppenheimer
Capital, L.P.) is a publicly traded Delaware limited partnership. Until
November 30, 1997, PIMCO Holdings' primary sources of income were its
proportionate (67%) share of the net income of Oppenheimer Capital, an equity
oriented investment management firm, and interest income from a 10%, $32.2
million note receivable (the "Equities Note") from an affiliate. As a result
of the acquisition of Oppenheimer Capital by PIMCO Advisors L.P. ("PIMCO
Advisors") described below, commencing December 1, 1997, PIMCO Holdings'
primary source of income has been its proportionate share of the net income of
PIMCO Advisors. Currently, PIMCO Holdings holds approximately 46 million PIMCO
Advisors units, representing a 43% general partner interest in PIMCO Advisors.
 
  The financial condition and results of operations of PIMCO Advisors are
discussed below under "--PIMCO ADVISORS L.P." The financial condition and
results of operations of Oppenheimer Capital are discussed below under "--
OPPENHEIMER CAPITAL."
 
COMBINATION OF OPPENHEIMER CAPITAL AND PIMCO ADVISORS
 
  On November 4, 1997, PIMCO Advisors acquired Oppenheimer Group, Inc.
("Opgroup"), whose subsidiary Oppenheimer Financial Corp. ("Opfin") owned the
32.4% managing general partner interest in Oppenheimer Capital and the one
percent general partner interest in PIMCO Holdings. In the transaction,
Opgroup became a subsidiary of PIMCO Advisors, and the Opgroup stockholders
received 2.1 million PIMCO Advisors Class A units and rights to exchange up to
$230 million of outstanding term notes of Opgroup for an additional 6.9
million PIMCO Advisors Class A units at $33 1/3 per unit. In connection with
the transaction, PIMCO Advisors split the one percent general partner interest
in PIMCO Holdings into a .01% general partner interest and a .99% limited
partner interest, and sold the general partner interest to its general
partner.
 
  On November 30, 1997, Oppenheimer Capital merged with a subsidiary of PIMCO
Advisors, with Oppenheimer Capital surviving (the "OpCap Merger"). In the
OpCap Merger, PIMCO Advisors acquired from PIMCO Holdings its 67.6% general
partner interest in Oppenheimer Capital in exchange for 26.1 million PIMCO
Advisors Class A units, an approximate 24% general partner interest in PIMCO
Advisors. As a result, Oppenheimer Capital became a wholly-owned subsidiary of
PIMCO Advisors, and the limited partner units of PIMCO Holdings came to
represent an indirect investment in the business of PIMCO Advisors. On
December 1, 1997, Holdings effected a 1.67 for 1 split of the PIMCO Holdings
units, so that each PIMCO Holdings unit outstanding after the split
represented an economic interest in one PIMCO Advisors unit.
 
  On December 31, 1997, PIMCO Advisors caused its 19.5 million publicly held
units to be contributed to PIMCO Holdings in exchange for an equal number of
PIMCO Holdings units. As a result, PIMCO Advisors ceased to be publicly
traded, and PIMCO Holdings general partner interest in PIMCO Advisors
increased to approximately 43%.
 
  Prior to the OpCap Merger, PIMCO Holdings reported its results of operations
and its financial position based on an April 30 fiscal year end. Upon
completion of the OpCap Merger, PIMCO Holdings changed its fiscal year to a
calendar year to correspond with that of PIMCO Advisors. Accordingly, the
period ending December 31, 1997 is a "stub" reporting period, eight months in
total, consisting of two three month periods and one two month period.
 
PRO FORMA FINANCIAL INFORMATION
 
  Because of the different ownership interests during the historical reporting
periods and the different elapsed times of the historical reporting periods,
management has included below certain pro forma financial information
 
                                      15
<PAGE>
 
as if the above discussed transactions had been completed as of January 1,
1996. Pro forma results eliminate the significant comparative differences in
the historical results of operations arising primarily from the inclusion of
67% of Oppenheimer Capital's stand alone results prior to November 30, 1997 as
compared with 24% of the consolidated results of PIMCO Advisors for December
of 1997 and 43% of such activities after December 31, 1997, and from certain
events effected in the transactions principally related to the creation and
amortization of intangible assets.
 
  The following table summarizes the unaudited condensed pro forma results of
operations of PIMCO Advisors and PIMCO Holdings for the calendar years ended
December 31, 1997 and 1996 as if the above discussed acquisition transactions
had been completed on January 1, 1996.

PIMCO ADVISORS HOLDINGS L.P.
 
COMPARATIVE RESULTS OF OPERATIONS
 
 Calendar 1997 pro forma compared to Calendar 1996 pro forma
 
  PIMCO Holdings realized $66 million as its proportionate share of pro forma
earnings of PIMCO Advisors (approximately 43%) as compared with $45.9 million
pro forma in 1996--an increase of $20.1 million or 43.8%. This increase was
the result of a comparable increase in the net income of PIMCO Advisors,
resulting from a $127.6 million, or 22.5%, pro forma increase in revenues
influenced predominantly by a pro forma 26.1% increase in managed assets as of
the end of the respective periods.
 
  The pro forma increase in managed assets aggregated $41.3 billion, which was
comprised of $16.0 billion of net cash inflows and $25.3 billion of net market
appreciation. There can be no assurances that future cash flows or market
activity will occur at the rates experienced in recent years.
 
  The operating expenses of PIMCO Advisors include compensation and related
costs, which increased a pro forma $54.3 million or 22.2%; other operating
expenses, which increased a pro forma $23.9 million or 21.5% and amortization
of intangibles and restricted units and options, which increased a pro forma
$1.4 million or 1.4%. Compensation and related costs are heavily influenced by
increased revenues because a substantial portion of such costs reflect
participation by key employees in the profitability of the investment advisor
subsidiaries. Other operating costs include occupancy and other costs and tend
to grow at a slower rate than revenues, however, as discussed below under
"PIMCO Advisors L.P. Overview", the implementation of a unified administrative
fee in the PIMCO Funds complex in 1997 resulted in costs previously borne by
the mutual funds directly being borne by the adviser with a corresponding new
revenue.
 
  The amortization of intangibles and restricted units and options in 1996 and
1997 includes a charge of approximately $25.8 million related to the complete
amortization of the intangible value (approximately $80.7 million) of PIMCO
Advisors master limited partnership (MLP) structure, originally scheduled to
expire on December 31, 1997. Under the change in the tax laws enacted in
August of 1997, PIMCO Holdings has elected to continue to be treated as a
publicly traded partnership, subject to a 3.5% federal tax on allocable gross
income from active businesses, however, there will be no specific intangible
amortization related to this structure in the future. It is expected,
therefore, that amortization of the remaining intangibles will approximate $80
million annually after 1997. Further, based upon current operating margins,
the federal tax would amount to an approximate 17% to 18% reduction in
otherwise reportable net income and an 11% to 12% reduction in cash flow
otherwise available for distribution.
 
 Historical eight months ended December 31, 1997 compared to the fiscal year
 ended April 30, 1997
 
  PIMCO Holdings realized $43.8 million as its proportionate share of the
earnings of its investees during the eight months ended December 31, 1997.
This included $39.8 million representing its approximate 67% ownership of
Oppenheimer Capital through November 30, 1997 and $4.0 million representing
its approximate 24% ownership of PIMCO Advisors for the month of December
1997. Equity in earnings of Oppenheimer Capital for the period included $2.8
million representing the proportionate share of a gain recognized by
Oppenheimer Capital upon the sale of the investment advisory contracts and
business relationships of the Quest for Value Dual Purpose Fund, Inc. to
OppenheimerFunds, Inc. ("OFI"). This compares with fiscal 1997 recorded
results of $52.8 million of equity in earnings of Oppenheimer Capital, which
results also reflected a $1.8 million gain from the sale of the Quest for
Value Funds investment advisory contracts and business relationships to OFI.
These two sales are referred to as the Quest sales. The comparative reduction
in earnings is predominantly due to the shorter relative time frames (seven
months of ownership of Oppenheimer Capital as compared to 12 months of
ownership) offset by increased managed assets during that period. Variances in
interest income, amortization of intangibles and other expenses are all due to
the difference in length of the respective reporting periods.
 
  Net income per unit amounted to $1.70 based upon a weighted average 25.8
million units outstanding.
 
 Comparison of historical fiscal years ended April 30, 1997, 1996 and 1995
 
  PIMCO Holdings recorded equity in earnings of Oppenheimer Capital for the
years ended April 30, 1997, 1996 and 1995 of $52.8 million, $58.1 million and
$31.1 million, respectively. Equity in earnings of
 
                                      18
<PAGE>
 
Oppenheimer Capital for the 1997 and 1996 fiscal years included gains
recognized by Oppenheimer Capital on the Quest sales of $1.8 million and $17.7
million, respectively. Equity in earnings of Oppenheimer Capital, excluding
the Quest sales, increased 26.4% to $51.0 million for the year ended April 30,
1997 from $40.4 million for the year ended April 30, 1996, as a result of
higher operating income at Oppenheimer Capital. Equity in earnings of
Oppenheimer Capital, excluding the Quest sales, increased 30.0% for the year
ended April 30, 1996 from $31.1 million for the year ended April 30, 1995,
primarily due to higher operating income at Oppenheimer Capital. Interest
income on the Equities Note for each of the years ended April 30, 1997, 1996
and 1995 totaled $3.2 million.
 
  Amortization of goodwill for each of the years ended April 30, 1997, 1996
and 1995 amounted to $2.6 million. Other expenses consist of New York City
unincorporated business tax ("UBT") computed at a rate of 4% of taxable
income. For the years ended April 30, 1997, 1996 and 1995, New York City UBT
amounted to $132,000, $132,000 and $873,000 respectively. The decline in New
York City UBT in fiscal 1996 reflects a change in the tax law effective on
January 1, 1995. As of that date, New York City UBT is imposed on the total
income of Oppenheimer Capital, and PIMCO Holdings is allowed to claim a credit
for its pro rata share of any New York City UBT paid by Oppenheimer Capital.
Previously, New York City UBT was assessed directly at the PIMCO Holdings
level.
 
  Net income amounted to $53.3 million or $2.06 per unit based on an average
of 25.8 million units outstanding for the year ended April 30, 1997; $58.6
million or $2.28 per unit based on an average of 25.5 million units
outstanding for the year ended April 30, 1996; and $30.8 million or $1.21 per
unit based on an average of 25.3 million units outstanding for the year ended
April 30, 1995. Included in the net income for the years ended April 30, 1997
and 1996 are gains on the Quest sales, which amounted to $1.8 million, or
$.07 per unit and $17.7 million, or $.69 per unit, respectively.
 
 Taxes
 
  PIMCO Holdings is not subject to federal, state, or local income taxes,
which are the obligations of the individual partners. However, beginning in
calendar year 1998, PIMCO Holdings elected to be subject to a 3.5% federal tax
on its share of PIMCO Advisors gross income from the active conduct of a trade
or business in order to retain its partnership status. The imposition of these
taxes will reduce both net income and cash available for distribution to
partners from levels that would otherwise be available. Similar taxes may be
imposed by states in which PIMCO Holdings is subject to such taxes.
 
 Liquidity and Capital Resources
 
  PIMCO Holdings is dependent upon the operating cash flow of PIMCO Advisors
(Oppenheimer Capital before November 30, 1997) for its liquidity and capital
resources. The liquidity and capital resources of PIMCO Advisors is discussed
separately below.
 
  For the eight months ended December 31, 1997, PIMCO Holdings declared total
distributions to holders of PIMCO Holdings units of $2.05 per unit, including
$.07 related to the Quest sales. For the years ended April 30, 1997, 1996 and
1995, PIMCO Holdings declared total distributions to holders of PIMCO Holdings
units of $2.10, $1.90 and $1.30 per unit, respectively. The total
distributions for the years ended April 30, 1997 and 1996 included special
distributions of $.06 and $.33, respectively, related to the Quest sales.
PIMCO Holdings' policy is to distribute substantially all of its net cash flow
on an annual basis. Distributions are declared and paid to unitholders of
record within thirty days following the end of each calendar quarter on March
31, June 30, September 30 and December 31 of each year. Because PIMCO
Holdings' sole business is to hold an investment as a general partner of PIMCO
Advisors, the cash flow of PIMCO Holdings consists of distributions from PIMCO
Advisors. The Amended and Restated Agreement of Limited Partnership of PIMCO
Advisors Holdings L.P., as amended (the "PIMCO Holdings Partnership
Agreement") requires the general partner of PIMCO Holdings to declare
quarterly distributions to the record holders of PIMCO Holdings units (the
"Unitholders") in an amount equal to the cash distributions from PIMCO
Advisors, less expenses and reserves. Because PIMCO Advisors currently pays
all expenses of PIMCO Holdings other than taxes, PIMCO Holdings' per-unit
distributions generally equal the PIMCO Advisors distributions, less
applicable taxes (see "--PIMCO Advisors L.P.--Liquidity and Capital Resources"
and "--Distributions").

PIMCO ADVISORS L.P.
 
GENERAL
 
  PIMCO Advisors is one of the largest investment management firms in the U.S.
with approximately $200 billion under management at December 31, 1997. PIMCO
Advisors provides high quality fixed income and equity investment management
to institutional and retail clients, offering the investment management
expertise, performance record and reputations of its institutional investment
managers, which include the fixed income oriented Pacific Investment
Management and the equity oriented Oppenheimer Capital. PIMCO Advisors'
business focuses on:
 
  Institutional Fixed Income. PIMCO Advisors provides fixed income investment
management to large and medium-sized foreign and domestic corporate and public
clients, including 59 or the largest 200 U.S. pension funds. Fixed income
management is led by Pacific Investment Management, which offers impressive
long term performance records across a diverse range of product offerings such
as total return, international and other duration or sector specific
strategies.
 
  Institutional Equity. PIMCO Advisors provides equity investment management
to institutional clients offering the investment management expertise of six
equity management groups, including the highly regarded Oppenheimer Capital.
PIMCO Advisors offers investors a variety of management styles, including
value, growth, quantitative and international management styles, as well as an
enhanced index based strategy.
 
  Institutional clients invest through separate accounts and pooled vehicles
such as the institutional share classes of PIMCO Funds, PIMCO Advisors' family
of 45 proprietary mutual funds. PIMCO Advisors offers its investment
management services to institutional clients through client service
representatives of its investment management groups.
 
  Retail Distribution. PIMCO Advisors offers the investment expertise of its
institutional investment managers to retail investors through the retail share
classes of the PIMCO Funds, which are distributed primarily through broker
dealers including PIMCO Funds Distributors LLC ("PFD", formerly known as PIMCO
Funds Distribution Company), a wholly-owed broker-dealer which distributes and
markets shares of the retail mutual funds of PIMCO Advisors. In addition,
PIMCO Advisors offers retail investors wrap fee accounts, variable annuity
products, 401K programs and various investment products through sponsored
trust companies.
 
  PIMCO Advisors' strategy is to increase the amount and diversification of
its assets under management through (i) growth in the institutional market
through providing high levels of client service and entering new markets, (ii)
growth in the retail market by building brand awareness and direct marketing
of the PIMCO Funds through its broker dealer network and through penetrating
additional distribution channels and (iii) new product offerings to
institutions and retail investors.
 
REVENUES
 
  PIMCO Advisors derives substantially all its revenues and net income from
advisory fees for investment management services provided through its
investment management subsidiaries to its institutional and individual
clients, and advisory, distribution and servicing fees for services provided
to the PIMCO Funds.
 
  Generally, such fees are determined based upon a percentage of client assets
under management and are billed quarterly to institutional clients, either in
advance or arrears, depending on the agreement with the client and monthly in
arrears to the PIMCO Funds. Revenues are determined in large part based upon
the level of assets under management, which itself is dependent upon factors
including market conditions, client decisions to add or withdraw assets from
PIMCO Advisors management, and PIMCO Advisors' ability to attract new clients.
In 1997, managed assets increased $89.5 billion. The increase resulted from
the acquisition of Oppenheimer Capital, managing $61.4 billion, as well as
from net new assets from new and existing clients of $12.1 billion and net
market appreciation of $16.0 billion. In 1996 and 1995 net cash inflow of
managed assets amounted to
 
                                      20
<PAGE>
 
$6.7 billion and $6.6 billion respectively, while net market appreciation
accounted for $8.1 billion and $16.4 billion respectively of the aggregate
growth in managed assets of $14.8 billion and $23.0 billion, respectively.
There can be no assurances that future cash flows or market activity will
occur at the rates experienced in recent years.
 
  In addition, PIMCO Advisors has certain accounts which are subject to
performance based fee schedules wherein performance relative to the S&P 500
Index or other benchmarks over a particular time period can result in
additional fees. These fees accrue on a quarterly or annual basis, depending
upon the specific investment advisory contract. Quarterly fees generally are
calculated based upon a rolling twelve-month performance result. Annual fees
have historically been weighted towards second and fourth quarter billings
although beginning in 1997 the third quarter reflects certain new annual
account billings. As a result, there is a seasonality to the recognition of
such fees. Such performance based fees can have a significant effect on
revenues, but also provide an opportunity to earn higher fees (or lower fees)
than could be obtained under fee arrangements based solely on a percentage of
assets under management. While no assurances can be given that PIMCO Advisors
will continue to earn any performance fees, such fees have aggregated $31.6
million, $22.5 million, and $19.1 million, or 6.1%, 5.7%, and 5.9% of total
revenues in 1997, 1996 and 1995, respectively.
 
  PIMCO Advisors' principal business units include Pacific Investment
Management, a fixed income manager, Oppenheimer Capital, a value based equity
manager, Columbus Circle Investors ("CCI"), a growth oriented equity manager,
Cadence Capital Management ("Cadence"), a growth oriented equity manager, NFJ
Investment Group ("NFJ"), a value based equity manager, Parametric Portfolio
Associates ("Parametric"), a quantitative based equity manager, and PFD, the
broker dealer distributing the PIMCO Funds. Revenues at each of these entities
are generally dependent upon the average levels of assets managed, and to a
lesser extent, the levels of net assets gathered in the case of PFD.
Accordingly, revenue impacts from growth, or declines, in managed assets are
more noticeable in periods subsequent to the change than in the period of
change itself.
 
  As discussed above, PIMCO Advisors completed the acquisition of Oppenheimer
Capital and its subsidiaries in a two step transaction, wherein an approximate
one-third interest was acquired November 4, 1997 and the remaining interest
was acquired November 30, 1997. Because control of Oppenheimer Capital was
achieved in the first step, the results of Oppenheimer Capital have been
consolidated with those of PIMCO Advisors since November 4, 1997.
 
  In January 1997, PIMCO Advisors restructured its proprietary mutual fund
operations into the single "PIMCO Funds" family of mutual funds. PIMCO Funds
are offered in up to five different share classes: Institutional and
administrative share classes primarily for institutional investors and, for
retail investors, front end load, back-end load and level load share classes.
In the reorganization, PIMCO Funds adopted a "unified fee" structure which has
specified advisory and administrative fees per fund. As a result, PIMCO
Advisors and Pacific Investment Management (and not the PIMCO Funds) bear the
risk of increases in service costs (including those of third-party service
providers such as transfer agents) and will directly benefit from any
decreases in those costs.
 
INTANGIBLE ASSETS
 
  PIMCO Advisors and its subsidiaries were formed on November 15, 1994, when
Pacific Asset Management LLC (formerly Pacific Financial Asset Management
Company) merged certain of its investment management businesses and
substantially all of its assets (the "PFAMCo Group") into Thomson Advisory
Group L.P. ("TAG LP") (the "Consolidation"). As described above, PIMCO
Advisors acquired Oppenheimer Capital in the fourth quarter of 1997.
 
  Intangible assets of approximately $284.9 million created by the
Consolidation represent the excess of the purchase price over the fair value
of net tangible assets of TAG LP deemed acquired by PFAMCo Group.
Approximately $80.7 million of the intangible assets represents the value
assigned to PIMCO Advisors MLP structure. Under previous tax law, an MLP was
exempt from federal and most state and local income taxes
 
                                      21
<PAGE>
 
through December 31, 1997. As discussed elsewhere, the tax status for publicly
traded partnerships has been extended. However, the value attributed to the
MLP structure has been amortized through the period ended December 31, 1997.
In connection with the acquisition of Oppenheimer Capital in the fourth
quarter of 1997 approximately $897.5 million of intangible assets was
recorded, representing the excess of the purchase price over the fair value of
the net tangible assets acquired. The remainder of all intangibles is being
amortized over the estimated useful life of 20 years.
 
DISTRIBUTIONS
 
  Net income per unit has historically been computed under the two-class
method which allocates net income to Class A and Class B units in proportion
to the Operating Profit Available for Distribution for each class. Operating
Profit Available for Distribution is defined by PIMCO Advisors partnership
agreement and is computed as the sum of net income plus non-cash charges from
the amortization of intangible assets, non-cash compensation expenses arising
from option and restricted unit plans, and losses of any subsidiary which is
not a flow-through entity for tax purposes. PIMCO Advisors Class A units were
entitled to a priority distribution of $1.88 per unit per year until December
31, 1997. Because of this, the amount of Operating Profit Available for
Distribution allocated to such units has been during some periods greater than
the amount allocated to PIMCO Advisors Class B units. As a result, prior to
1997 the net income allocated per Class A unit was greater than the net income
allocated per Class B unit. In addition, because of the priority distribution,
the initial dilution to net income per unit from the assumed exercise of unit
options was applied entirely to PIMCO Advisors Class B units. However, growth
in both net income and Operating Profit Available for Distribution in 1997
beyond the priority levels has resulted in the allocations of income and
distributions per unit to be equal across all classes. Distributions are
declared and paid to unitholders of record (including PIMCO Holdings) within
thirty days following the end of each calendar quarter. The Class A unit
distribution preference ended with the payment of the distribution for the
fourth quarter of 1997, and on March 1, 1998, all PIMCO Advisors Class B units
were converted into Class A units.
 
 
  PIMCO Advisors distributes on an annual basis cash in an amount equal to
Operating Profit Available for Distribution (as defined in the Amended and
Restated Agreement of Limited Partnership of PIMCO Advisors L.P. (the "PIMCO
Advisors Partnership Agreement")) less any amount deemed required for capital
expenditures, future payments of indebtedness, as reserves or otherwise in the
business of PIMCO Advisors. In general, the Management Board of PIMCO Advisors
evaluates distribution levels late in the fourth quarter of each year based on
expected year end earnings and the anticipated earnings for the ensuing year.
The Management Board of PIMCO Advisors has set a quarterly distribution rate
of $0.60 per PIMCO Advisors unit for the first three calendar quarters of
1998, which equates to a distribution rate at PIMCO Holdings (after taxes at
PIMCO Holdings) of $0.53 per unit.
 
  Actual distribution levels will depend on the financial performance of PIMCO
Advisors, and there can be no assurance that the stated distribution rates
will be achieved. Distributions made by PIMCO Holdings will depend on the
profitability of the investment management business of PIMCO Advisors, which
is affected in part by overall economic conditions and other factors affecting
capital markets generally, which are beyond the control of PIMCO Holdings and
PIMCO Advisors. In addition, the general partners of PIMCO Advisors may, in
determining the amount of distributions, deduct any amount from Operating
Profit Available for Distribution the general partners deem may be required
for capital expenditures, reserves or otherwise in the business of PIMCO
Advisors. To the extent PIMCO Advisors or PIMCO Holdings retains profits in
any year, unitholders may have taxable income from PIMCO Holdings that exceeds
their cash distributions.
 
COMPARATIVE RESULTS OF OPERATIONS
 
 Year Ended December 31, 1997 Compared to Year Ended December 31, 1996
 
  PIMCO Advisors consolidated 1997 revenues, including those of its wholly-
owned distributor, PFD, were $516.7 million, compared to revenues of $392.0
million in 1996. Advisory revenues in this comparison increased
 
                                      22
<PAGE>
 
$114.9 million to $453.2 million in 1997. PFD's revenues increased $9.8
million to $63.5 million in 1997. The acquisition of Oppenheimer Capital
during the fourth quarter of 1997 accounts for a portion of the individual
increases in the respective operational line items on a year over year basis.
Most significantly, approximately $39.0 million of revenues, $14.5 million in
compensation and related expenses, and $2.8 million of restricted unit
amortization arose in the post acquisition period. The impact of Oppenheimer
Capital on other cost categories for the post acquisition period was generally
not material because of the short time period involved. In addition to the
revenues from Oppenheimer Capital, for most operating entities revenue
increases resulted from the commitment of new assets primarily by
institutional clients and increases in the market value of existing assets
under management. These increases were further enhanced by an increase in
performance based fees, which amounted to $31.6 million in 1997 as compared to
$22.5 million in 1996. The increase in performance based fees occurred
principally in equity index portfolio products seeking to outperform the S&P
500 Index. CCI continued to experience net outflows of managed assets,
principally in large-cap separate accounts, aggregating $6.1 billion in 1997,
resulting in a decrease in its revenues of $6.1 million or 9.6%.
 
  Compensation and benefit expenses in 1997 of $225.8 million were $52.3
million higher than 1996, reflecting additional staffing at virtually all
subsidiaries, and increased profit sharing at the investment management
subsidiaries due to improved profitability as well as the aforementioned
impact of the Oppenheimer Capital acquisition. The total number of employees
increased from 547 as of December 31, 1996 to 980 as of December 31, 1997,
inclusive of 365 employees at Oppenheimer Capital.
 
  Commission expenses increased by $9.0 million or 23.9% in 1997 as compared
with 1996. Commission expenses are primarily incurred by PFD and are paid
primarily to broker-dealers and their sales people for the sale of PIMCO
Advisors retail-oriented mutual funds. These include "up-front" commissions
paid at the time of sale of the mutual funds, "trail" commissions for the
maintenance of assets in the mutual funds and service fee commissions paid for
services provided to mutual fund shareholders. The level of commission expense
will vary according to the level of assets in the mutual funds (on which trail
and service fee commissions are determined) and on the level of sales of
mutual funds (on which up-front commissions are determined). Trail and service
fee commissions are generally paid quarterly beginning one year after sale of
the mutual funds. Therefore, at any given time, trail and service fee
commissions will be paid on only the mutual fund assets that qualify for such
payments. In 1997, trail and service fee commissions increased to $35.6
million, an increase of $5.3 million or 17.5%, compared to 1996. This increase
is related to an increase in the underlying qualifying assets. Up-front
commissions increased from $7.4 million in 1996 to $11.1 million in 1997, an
increase of $3.7 million or 50.0%. This is a result of increases in total
sales volume and the mix of share classes sold.
 
  Restricted unit and option plan costs increased $3.0 million, or 58.6% from
1996. This is predominantly due to the award of restricted units in the
Oppenheimer Capital acquisition that will result in an annual charge of
approximately $14 million in this cost category over the five year vesting
period. Coupled with existing charges to this line item, the 1998 charge is
expected to aggregate approximately $24.4 million.
 
  Marketing and promotional costs increased $5.6 million or 51.1% in 1997
compared to 1996. Increases commensurate with increased activities occurred at
most entities, including the effects of Oppenheimer Capital of approximately
$1.4 million. In addition, the retail fund complex adopted a unified
administrative fee structure in 1997 which results in costs previously borne
directly by the funds to be borne by the advisor with a concurrent revenue
received by the advisor. The majority of those newly borne costs are reflected
in the marketing and promotional and general and administrative cost
categories.
 
  Occupancy and equipment costs increased $2.6 million or 28.3% in 1997
compared to 1996. The increase relates to increased depreciation of equipment
and inflationary facilities cost increases at all entities, as well as the
impact of Oppenheimer Capital of approximately $1.5 million during the period
following the acquisition.
 
  General and administrative costs increased $9.8 million or 55.5% in 1997
compared to 1996. As noted above, the retail fund complex adopted a fixed
administrative fee basis in 1997 resulting in increases to this cost category
for expenses previously borne directly by the funds.

  Other expense includes such items as interest expense, consulting costs,
reimbursement agreements and other, and reflects a net increase of $4.5
million in 1997 compared to 1996. Interest expense on debt assumed in the
Oppenheimer Capital acquisition of approximately $2 million, as well as
increased activities at PIMCO Advisors related to acquisition analysis, and
generally expanded activities at all of the operating subsidiaries accounts
for this increase.
 
  Amortization of intangibles increased $7.5 million due to the intangibles
created in the Oppenheimer Capital acquisition. The future annual charges
associated with those intangible assets are expected to approximate
$45 million. However, as noted earlier, the completed amortization of the
originally established intangible asset allocable to the MLP status of PIMCO
Advisors will result in other intangible amortization reducing to
approximately $10 million annually commencing in 1998, for a future aggregate
annual charge of approximately $55 million.
 
 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  PIMCO Advisors consolidated 1996 revenues, including those of its wholly-
owned distributor, PFD, were $392.0 million, compared to revenues of $323.0
million in 1995. Advisory revenues in this comparison increased $56.7 million
to $338.3 million in 1996. PFD's revenues increased $12.3 million to $53.7
million in 1996. Revenue increases resulted from the commitment of new assets
primarily by institutional clients and increases in the market value of
existing assets under management. These increases were further enhanced by an
increase in performance based fees, which amounted to $22.5 million in 1996 as
compared to $19.1 million in 1995. The increase in performance based fees
occurred principally in fixed income portfolio products seeking to outperform
relative benchmarks.
 
  Compensation and benefit expenses in 1996 of $173.5 million were $24.4
million higher than 1995, reflecting additional staffing at virtually all
subsidiaries, and increased profit sharing at the investment management
subsidiaries due to improved profitability. The total number of employees
increased 5.0% from 521 as of December 31, 1995 to 547 as of December 31,
1996.
 
  Commission expenses increased by $9.0 million or 31.3% in 1996 as compared
with 1995. In 1996, trail and service fee commissions increased to $30.3
million, an increase of $6.1 million or 25.2%, compared to 1995. This increase
is related to an increase in the underlying qualifying assets. Up-front
commissions increased from $4.5 million in 1995 to $7.4 million in 1996, an
increase of $2.9 million or 64.4%. This is a result of increases in total
sales volume and the mix of share classes sold.
 
  Marketing and promotional costs increased $1.9 million or 20.9% in 1996
compared to 1995. This increase occurred at most entities, but primarily at
PFD and Pacific Investment Management. At PFD, increased mutual fund share
sales correlate to the increase. At Pacific Investment Management, increased
travel costs comprise the majority of the increase.
 
  General and administrative costs increased $6.2 million or 54.4% in 1996
compared to 1995. Pacific Investment Management converted its institutional
fund family to a fixed administrative fee basis in October 1995 resulting in
increases to this cost category for expenses previously borne directly by the
funds. There is a corresponding increase in revenues related to this
conversion. These incremental costs account for approximately $6.0 million of
the increase.
 
  Professional fees increased $2.3 million or 71.9% in 1996 compared to 1995.
This increase resulted primarily from the costs associated with the
restructuring of the three mutual fund "families" in December of 1996.
 
  Other expense includes such items as consulting costs, reimbursement
agreements and other, and reflects a net increase of $2.6 million in 1996
compared to 1995. This increase is comprised principally of lower levels of
reimbursement under agreements with Pacific Life that became effective in
November 1994.
 
                                      24
<PAGE>
 
  Amortization of intangibles, options and restricted units decreased $1.5
million principally due to the accelerated vesting in 1995 of outstanding
options and restricted units for certain employees terminating during 1995.
 
 Liquidity and Capital Resources
 
  PIMCO Advisors business has not historically been capital intensive. In
general, working capital requirements have been satisfied out of operating
cash flow or short-term borrowings. PIMCO Advisors will make quarterly profit-
sharing payments to employees and distributions to its unitholders. PIMCO
Advisors may need to finance profit sharing payments using short-term
borrowings.
 
  PIMCO Advisors had approximately $67.9 million of cash and cash equivalents
and short-term investments at December 31, 1997 compared to approximately
$52.8 million at December 31, 1996, and compared to approximately $46.5
million at December 31, 1995. The increases were due to the timing of payment
of certain liabilities offset by the funding of "B" Share commissions to
brokers. "B" Shares involve the payment of commissions to the selling broker
by the distributor at the time of sale of mutual fund shares. Through deferred
sales charges to the investor, or 12-b1 plans with the mutual fund, these
"front-end" commissions are recouped by the distributor over a period of
years. PIMCO Advisors excess liquidity, after distributions to its
unitholders, is used for general corporate purposes including profit-sharing
payments and brokers' commissions on sales of mutual fund shares distributed
without a front-end sales load. To the extent that the level of such
commissions may increase due to the introduction of new products and mutual
fund pricing structures, an alternate financing source may be needed. However,
PIMCO Advisors has made no decision as to the source or necessity of such
financing.
 
  PIMCO Advisors distributes substantially all of its Operating Profit
Available for Distribution, after appropriate reserves, to its partners.
Distributions have been paid quarterly, in arrears, on the units outstanding
to unitholders of record on the thirtieth day of the first month following
each quarter-end. Effective December 31, 1997, such distributions are payable
to unitholders of record on the last day of the quarter. Distribution
declarations in 1997 were $2.570 for the PIMCO Advisors Class A limited and
general partner units and $2.564 for the PIMCO Advisors Class B limited
partner units. These amounts reflect Operating Profit Available for
Distribution for the fourth quarter of 1996 and the four quarters of 1997. The
declaration of $.58 per unit for all classes related to the fourth quarter of
1997 was payable subsequent to year end. Actual cash distributions per unit in
1996 were $1.88 for the PIMCO Advisors Class A limited and general partner
units and were $1.658 for the PIMCO Advisors Class B limited partner units.
These amounts reflect Operating Profit Available for Distribution for the
fourth quarter of 1995 and for the first three quarters of 1996. The Class A
unit distribution preference ended with the payment of the distribution for
the fourth quarter of 1997, and on March 1, 1998, all PIMCO Advisors Class B
units were converted into Class A units.
 
  PIMCO Advisors assumed $230.0 million of 6% exchangeable debt in connection
with the Oppenheimer Capital acquisition in November 1997. In December of
1997, $146.9 million of that debt was exchanged for Class A units at a rate of
$33 1/3 per unit. The remaining $83.1 million of such debt is expected to be
exchanged for units on the same terms upon the expiration of certain tax
contingencies over the next 6 to 7 years. In November 1997, PIMCO Advisors
amended its April 1996, four year revolving line of credit to increase the
available amount for working capital purposes from $25 million to $75 million.
As of year end, $30 million was outstanding under this facility. PIMCO
Advisors is currently negotiating an expanded, syndicated five year revolving
credit facility, expected to be finalized early in 1998.
 
ECONOMIC AND OTHER FACTORS
 
  The general economy including interest rates, inflation and client responses
to economic factors will affect, to some degree, the operations of PIMCO
Advisors. As a significant portion of assets under management are fixed income
funds, fluctuations in interest rates could have a material impact on the
operations of PIMCO Advisors. In addition, general market conditions, or
corrections in the equity markets could also have a
 
                                      25
<PAGE>
 
material impact on the operations of PIMCO Advisors. PIMCO Advisors advisory
business is generally not capital intensive and therefore any effect of
inflation, other than on interest rates, is not expected to have a significant
impact on its operations or financial condition. Client responses to the
economy, including decisions as to the amount of assets deposited may also
impact the operations of PIMCO Advisors. Any resulting revenue fluctuations
may or may not be recoverable in the pricing of services offered by PIMCO
Advisors.
 
  During 1997, assets under management for PIMCO Advisors and its
subsidiaries, excluding the impact of Oppenheimer Capital, increased $28.1
billion. During 1996 and 1995, assets under management for PIMCO Advisors and
its subsidiaries increased $14.8 billion and $23.0 billion, respectively.
While net cash inflows in 1997, 1996 and 1995 for PIMCO Advisors, as a whole,
were significant ($12.1 billion in 1997, $6.7 billion 1996 and $6.6 billion in
1995), CCI experienced substantial net cash outflows in the same periods
(including $6.1 billion in 1997) predominantly from its "large cap" separate
account clients, attributable in large part to underperformance measured
against relevant benchmarks. As of December 31, 1997, "large cap" separate
accounts at CCI aggregated approximately $1.6 billion.
 
  PIMCO Advisors and its subsidiaries are aware of and addressing the issues
surrounding technology and the year 2000. The major subsidiaries have made
most internal modifications and the remaining systems to be tested and or
modified are not expected to result in any material cost or impact on
operations.

OPPENHEIMER CAPITAL
 
OVERVIEW
 
  Oppenheimer Capital's results of operations include those of its
institutional investment management business and those of its subsidiary
entities; OpCap Advisors, OCC Distributors ("Distributors"), Oppenheimer
Capital Limited, Oppenheimer Capital Trust Company ("Opcap Trust"), and 225
Liberty Street Advisers, L.P., formerly AMA Investment Advisers, L.P. ("AMA
Advisers"). The results for the year ended April 30, 1997 also include
Saratoga Capital Management ("Saratoga"), which was sold on April 29, 1997.
 
  For the periods presented, Oppenheimer Capital's operations have been
characterized by substantial increases in assets under management. This growth
has been from four principal sources. First, new clients have entered into
investment management agreements and existing clients have added funds to
their accounts under management, offset in part by net outflows from
institutional accounts. Second, rising securities price levels have increased
the market values of investment portfolios. Third, mutual funds and variable
annuities managed by OpCap Advisors have added to assets under management due
to increased sales and market appreciation. Fourth, wrap fee assets have
increased due to new accounts opened, expanded distribution to broker-dealers
and market appreciation. The growth in assets under management has been
tempered by Oppenheimer Capital's withdrawal from the low fee rate option
management business in fiscal 1996 in order to concentrate on businesses
offering higher returns. For the periods presented, the option management
business had no material effect on revenues or profitability. Revenues are
generally derived from charging a fee based on the net assets of clients'
portfolios. Revenues for all periods presented consist principally of
investment management fees.
 
  In fiscal 1996, Oppenheimer Capital began to implement a strategic decision
to withdraw from selling directly to the retail market, and to instead market
directly to institutions with strong retail distribution capabilities. In
November 1995, Oppenheimer Capital withdrew from the open-end mutual fund
distribution business (see "Gain on Quest Sale" below) and began to eliminate
retail operations at AMA Advisers, completing this process in the first
quarter of fiscal 1997. Oppenheimer Capital also reduced the losses incurred
by Saratoga throughout fiscal 1997, and during the fourth quarter of fiscal
1997 sold its interest in Saratoga. Additionally, Oppenheimer Capital
terminated the distribution of unit investment trusts during the fourth
quarter of fiscal 1997.
 
  The value of total assets under management increased 19.9% to $61.4 billion
at December 31, 1997 from $51.2 billion at April 30, 1997. For eight months
ended December 31, 1997, assets under management for separately managed
accounts increased 12.9% to $37.5 billion, mutual fund and other commingled
products increased 32.9% to $16.0 billion, and wrap fee accounts increased
31.8% to $7.9 billion. The growth of separately managed accounts was tempered
by net outflows from existing accounts as clients rebalanced their portfolios
and shifted equity assets to other asset classes.
 
  The value of total assets under management increased 26.3% to $51.2 billion
at April 30, 1997 from $40.6 billion at April 30, 1996. The growth of assets
under management was tempered by the loss of $530 million in mutual fund
assets as a result of the closed-end Quest for Value Dual Purpose Fund
redeeming all income fund shares and converting to an open end fund. For the
year ended April 30, 1997, assets under management for separately managed
accounts increased 18.1% to $33.2 billion, mutual fund and other commingled
products increased 33.4% to $12.0 billion, and wrap fee accounts increased
73.7% to $6.0 billion.
 
  The value of total assets under management increased 27.6% to $40.6 billion
at April 30, 1996 from $31.8 billion at April 30, 1995. The growth of assets
under management was tempered by the loss of $1.5 billion in option management
accounts with a low effective fee rate and a reduction of $300 million in
fixed income mutual fund assets as a result of the Quest sale. For the year
ended April 30, 1996, assets under management for separately managed accounts
increased 25.8% to $28.1 billion from $22.3 billion, mutual fund and other
commingled products increased 43.9% to $9.0 billion from $6.3 billion, and
wrap fee accounts increased 92.3% to $3.5 billion from $1.8 billion.

GAIN ON QUEST SALE
 
  On November 22, 1995, Oppenheimer Capital completed the Quest sale to OFI,
which is unrelated to Oppenheimer Capital, for an initial purchase price
payment of $41.7 million. In December 1996, a deferred purchase price payment
of $3.8 million was received by Oppenheimer Capital as a result of the assets
of the six merged fixed income funds being at stated levels. The gains on the
sale, before New York City UBT and minority interest, amounted to $2.8 million
for the year ended April 30, 1997, and $27.7 million for the year ended
April 30, 1996.
 
  Total assets of the twelve funds were $1.7 billion at November 21, 1995. The
six equity funds involved, representing $1.4 billion of those assets, continue
to be managed by Advisors under a subadvisory contract with OFI, which allows
the current portfolio management teams to remain in place. The six equity
funds were renamed the Oppenheimer Quest for Value funds (the "Quest funds").
The six fixed income funds, representing approximately $300 million of those
assets, were merged into comparable funds managed by OFI.
 
  The overall impact of the Quest sale on Oppenheimer Capital's results has
been highly positive. Although the fee rate as a subadviser is less than the
previous fee rate, assets in the six equity funds have increased more than
fourfold to $6.7 billion at January 31, 1998 as a result of the extensive
distribution capabilities of OFI and market appreciation. In addition,
Oppenheimer Capital has eliminated distribution expenses related to these
funds. Reflecting the impact of these various factors, the profitability of
Oppenheimer Capital's mutual fund business has increased since the Quest sale.
 
  Oppenheimer Capital implemented a portion of the mutual fund distribution
cost savings prior to the close of the Quest sale, and results for the quarter
ended April 30, 1996 reflected those savings. In addition, as a result of the
sale, significant expenditures that would have been made in systems,
technology, sales and marketing capabilities, and new product development have
not been necessary.
 
  On January 31, 1997, the closed-end Quest for Value Dual Purpose Fund (the
"Dual Purpose Fund") redeemed all of its income shares as required by its
Articles of Incorporation, and on February 28, 1997, the Fund converted to an
open-end fund. The investment contracts and other business relationships were
sold to OFI (the "Dual Purpose Fund sale"), and OpCap Advisors now serves as
subadviser to the Dual Purpose Fund under an agreement with OFI. The
subadvisory fee is significantly lower than the management fee previously
earned by Oppenheimer Capital. Annual subadvisory fees related to the Dual
Purpose Fund are expected to approximate $1.0 million annually, while
Oppenheimer Capital received $5.0 million of investment management fees for
the fiscal year ended April 30, 1997.
 
  On July 18, 1997, Oppenheimer Capital received an initial payment of $7.0
million related to the Dual Purpose Fund sale, and recorded a pre-tax gain of
$4.4 million
 
COMPARATIVE RESULTS OF OPERATIONS
 
  As a result of the change in the year end to a calendar year end, the period
ended December 31, 1997 is only eight months, a 33% shorter time frame than
all other periods being compared. Therefore, revenue, expense and net income
generally show overall decreases as a result of the shorter time period ended
December 31, 1997 compared to the year ended April 30, 1997, while generally
showing annualized increases.
 
 Operating Revenues--Eight Months Ended December 31, 1997 and Years Ended
 April 30, 1997, 1996 and 1995
 
  Total operating revenues decreased 18.2% for eight months (a 33% shorter
time frame) ended December 31, 1997 to $148.9 million from $182.0 million for
the year ended April 30, 1997, increased 15.0% for the year ended April 30,
1997 from $158.2 million for the year ended April 30, 1996 and increased 21.8%
for the year ended April 30, 1996 from $129.9 million for the year ended April
30, 1995. Total operating revenues include investment management fees, net
distribution assistance and commission income, and interest and dividends.
 
                                      28

  Investment management fees decreased 17.6% to $144.8 million for the eight
months ended December 31, 1997 from $175.8 million for the year ended April
30, 1997. This decrease is due to the eight month period being compared to a
twelve month period, and was offset in part by a 27.6% increase in average
assets under management, which increased to $58.4 billion for the eight months
ended December 31, 1997 compared to $45.8 billion for the year ended April 30,
1997.
 
  Investment management fees increased 16.2% to $175.8 million for the year
ended April 30, 1997 from $151.3 million for the year ended April 30, 1996.
This increase is a result of average assets under management increasing 24.7%
to $45.8 billion for the year ended April 30, 1997 from $36.7 billion for the
year ended April 30, 1996. Investment management fee revenue grew less than
assets under management due to the lower subadvisory fee rates earned on the
Quest funds than the advisory fee rate prior to the Quest sale. These lower
fee rates were more than offset by asset growth for these funds and the
elimination of mutual fund distribution expenses. Annual subadvisory fees
would be $19.3 million, based on assets under management at January 31, 1998
and current fee arrangements--higher than the previous $15.7 million of annual
fees for the twelve Quest for Value Funds at November 22, 1995. Assets in the
six equity funds have increased more than fourfold to $6.7 billion at January
31, 1998 from $1.4 billion on November 22, 1995, reflecting record fund sales
and market appreciation.
 
  In addition, investment management fee revenue grew less than the increase
in assets under management due to a decline in performance fees earned in
fiscal 1997 to $1.2 million from $3.0 million in fiscal 1996. These decreases
were offset in part by investment management fees increasing due to higher fee
realizations resulting from a continued shift in the asset mix toward higher
effective fee rate businesses such as variable annuities and wrap fee
accounts.
 
  Investment management fees increased 26.9% for the year ended April 30, 1996
from $119.2 million for the year ended April 30, 1995, primarily as a result
of average assets under management increasing 23.8% for the year ended April
30, 1996 from $29.7 billion for the year ended April 30, 1995. This increase
also reflects higher fee realizations as a result of a shift in the asset mix
toward higher fee rate businesses including mutual funds, variable annuities
and wrap fee accounts, and the withdrawal from the option management business,
which had very low fee rates. Offsetting the increase in part was the lower
fee rate earned subadvising the Quest funds as a result of the Quest sale.
 
  Net distribution assistance and commission income decreased 39.1% to $3.0
million for the eight months ended December 31, 1997 from $4.9 million for the
year ended April 30, 1997. This decrease is primarily due to eight months
being compared to twelve months, as well as lower unit investment trust
commission income as Oppenheimer Capital exited this business in April 1997.
 
  Net distribution assistance and commission income decreased 18.9% for the
year ended April 30, 1997 from $6.1 million for the year ended April 30, 1996.
This decrease reflects reduced commission and distribution income as a result
of the Quest sale and lower unit investment trust commission income due to
reduced demand for fixed income unit investment trusts. This decrease was
offset in part by a $1.3 million increase in certificate of deposit commission
income as a result of increased demand for funds by banks.
 
  Net distribution assistance and commission income decreased 42.1% for the
year ended April 30, 1996 from $10.4 million for the year ended April 30, 1995
primarily as a result of a $3.5 million decline in certificate of deposit
commission income as a result of lower demand for funds by banks, decreased
unit investment trust commission income, and reduced commission and
distribution income as a result of the Quest sale in November 1995.
 
  Interest and dividend income decreased 7.6% to $1.2 million for the eight
months ended December 31, 1997 from $1.3 million for the year ended April 30,
1997. This decrease is due to the comparison of eight months to twelve months
which was offset in part by higher average cash balances.
 
                                      29
<PAGE>
 
  Interest and dividend income increased 39.7% for year ended April 30, 1997
from $.9 million for the year ended April 30, 1996. This increase can be
attributed to higher average cash balances.
 
  Interest and dividend income increased to $.9 million for the year ended
April 30, 1996 from $275,000 for the year ended April 30, 1995. This increase
can be primarily attributed to the interest earned on the proceeds received
from the Quest sale.
 
 Operating Expenses--Eight Months Ended December 31, 1997, and Years Ended
 April 30, 1997, 1996 and 1995
 
  Total operating expenses decreased 18.5% for the eight months (a 33% shorter
time frame) ended December 31, 1997 to $84.0 million from $103.1 million for
the year ended April 30, 1997, increased 7.9% for the year ended April 30,
1997 from $95.6 million for the year ended April 30, 1996 and increased 15.0%
for the year ended April 30, 1996 from $83.1 million for the year ended April
30, 1995.
 
  Oppenheimer Capital's most significant expense category is compensation and
benefits, which includes salaries, bonuses, sales commissions, incentive
compensation and other payroll related expenses. Compensation and benefits
expenses decreased 14.6% to $66.3 million for the eight months ended December
31, 1997 from $77.7 million for the year ended April 30, 1997, increased 12.9%
for the year ended April 30, 1997 from $68.8 million for the year ended April
30, 1996 and increased 24.2% for the year ended April 30, 1996 from $55.4
million for the year ended April 30, 1995. For the eight months ended December
31, 1997 compared to the year ended April 30, 1997, the decrease was due to
the shorter time period which was offset by the following increases: For the
eight month period and for both years, compensation and benefits increased
primarily due to higher incentive compensation costs due to increased new
business, higher operating profits and increased participation by key
executives in incentive compensation plans as a result of industry competitive
pressures and their individual contributions to firm profitability. In
addition, compensation and benefits expense increased due to staff salary
increases and additions to staff to support expanding businesses. These
increases were offset in part by significant staff reductions at OCC
Distributors, AMA Advisers, and in mutual fund accounting in fiscal 1996 with
most staff reductions occurring after the Quest sale in November 1995. In
fiscal 1997, staff size was reduced as a result of the sale of Oppenheimer
Capital's 50% interest in Saratoga and the termination of the unit investment
trust distribution effort during the fourth fiscal quarter. Reflecting these
reductions, staff size declined to 344 at April 30, 1997 from 348 at April 30,
1996, and from 417 at April 30, 1995.
 
  Occupancy expense decreased 28.3% for the eight months December 31, 1997 to
$4.7 million from $6.6 million for the year ended April 30, 1997, decreased
4.4% for the year ended April 30, 1997 from $6.9 million for the year ended
April 30, 1996 and increased 6.8% for the year ended April 30, 1996 from
$6.4 million for the year ended April 30, 1995. The decrease for the eight
month period ending December 31, 1997 reflects the shorter time period
involved, as well as adjustments made to rent escalation accruals during the
period. The decrease for the year ended April 30, 1997 reflects reduced rent
expense as a result of the termination of leases at AMA Advisers as well as
adjustments made to rent escalation accruals during the fiscal year. For the
year ended April 30, 1996, the increase was attributable to increased
amortization expense relating to leasehold improvements and increased
equipment rental costs.
 
  Oppenheimer Capital subleases a portion of its space at the Oppenheimer
Tower, World Financial Center, from CIBC Oppenheimer Corp. ("Opco"), a former
affiliated broker-dealer, paying a pro rata share of Opco's lease payments,
based on the percentage of total space leased. Oppenheimer Capital is
currently reviewing its space needs to house its growing business.
 
  General and administrative expenses decreased 29.9% for the eight months
ended December 31, 1997 to $8.8 million from $12.5 million for the year ended
April 30, 1997, increased 1.6% for the year ended April 30, 1997 from $12.3
million for the year ended April 30, 1996 and increased 15.4% for the year
ended April 30, 1996 from $10.7 million for the year ended April 30, 1995. The
decrease in general and administrative expenses in the eight month period
ended December 31, 1997 compared to the year ended April 30, 1997 is due to
the

shorter time period involved, and was partially offset by increased
investments in computer technology described below. The rate of growth of
general and administrative expenses slowed in fiscal 1996 and continued in
fiscal 1997 as Oppenheimer Capital realized cost savings from the Quest sale
and cost reductions at AMA Advisers. As a result of the Quest sale in November
1995, Oppenheimer Capital was able to eliminate all of its outstanding bank
loans and related interest expense. Offsetting these reductions in both fiscal
1997 and 1996 were increased costs incurred in connection with the development
of new businesses and increased investments in computer equipment and software
as a result of increased technical support for professional and administrative
staff and higher professional services expense due to the expansion of
Oppenheimer Capital's business.
 
  Promotional expenses decreased 34.1% for the eight months ended December 31,
1997 to $4.2 million from $6.3 million for the year ended April 30, 1997;
decreased 16.7% for the year ended April 30, 1997, from $7.6 million for the
year ended April 30, 1996 and decreased 28.3% for the year ended April 30,
1996 from $10.6 million for the year ended April 30, 1995. The decrease in
promotional expenses for the eight months ended December 31, 1997 compared to
the year ended April 30, 1997 was due to the shorter time period involved. The
decrease in promotional expenses for both fiscal years was due primarily to a
reduction in expenses incurred by OCC Distributors as a result of the
elimination of the open-end mutual fund distribution effort, and the retail
operations of AMA Advisers, and was offset in part by increased expenses in
Oppenheimer Capital's new businesses due to increased travel and entertainment
expenses as a result of new business activities. In addition, promotional
expenses decreased in fiscal 1997 due in part to decreased promotional
activities at Saratoga.
 
 Operating Income--Eight Months Ended December 31, 1997 and Years Ended April
 30, 1997, 1996 and 1995
 
  Operating income decreased 17.6% for the eight months (a 33% shorter time
frame) ended December 31, 1997 to $65.0 million from $78.1 million for the
year ended April 30, 1997; increased 25.9% for the year ended April 30, 1997
from $62.7 million for the year ended April 30, 1996 and increased 33.8% for
the year ended April 30, 1996 from $46.8 million for the year ended April 30,
1995. For the eight months ended December 31, 1997, the operating profit
margin rose to 43.6% from 43.4% for the year ended April 30, 1997; for the
year ended April 30, 1997, the operating profit margin expanded from 39.6% for
the year ended April 30, 1996; and in the year ended April 30, 1996, the
operating profit margin increased from 36.1% for the year ended April 30,
1995. Operating income decreased for the eight months ended December 31, 1997
compared to the year ended April 30, 1997 due to the shorter time period
involved while operating profit margins continued to improve. The increase in
operating income and operating profit margins for all annualized periods
presented is due to rising securities price levels, strong new business growth
and the resultant revenue increase combined with Oppenheimer Capital
controlling the rate of expense growth. In both fiscal 1997 and fiscal 1996,
the operating revenue growth rate exceeded the operating expense growth rate.
This was accomplished primarily from the decision to withdraw from the mutual
fund distribution business (the Quest sale), which was completed in the final
quarter of fiscal 1996, and the suspension of retail sales activities at AMA
Advisers. This process, which began in fiscal 1996, was completed in the first
quarter of fiscal 1997. In addition, losses from Saratoga were reduced to $1.4
million in fiscal 1997 from $2.5 million in fiscal 1996, and during the fourth
quarter of fiscal 1997, Oppenheimer Capital sold its 50% interest in Saratoga.
 
 Taxes
 
  Oppenheimer Capital is not subject to federal, state, or local income taxes,
which are the obligations of the individual partners. Oppenheimer Capital was,
however, subject to New York City UBT of $3.0 million, $3.2 million, $3.6
million and $1.2 million, respectively, for the eight months ended December
31, 1997 and for the years ended April 30, 1997, 1996 and 1995. The decrease
in New York City UBT expense for the eight month period ended December 31,
1997 compared to the fiscal year ended April 30, 1997 is due to the shorter
time period involved , and was offset in part by the gain recorded on the Dual
Purpose Fund sale. The decrease in New York City UBT expense in fiscal 1997
compared to fiscal 1996 is due to a decline in net income in fiscal 1997 as a
result of the $27.7 million gain recorded for the Quest sale in fiscal 1996,
compared with the $2.8 million gain in fiscal 1997. This decline was offset in
part by higher operating income in fiscal 1997 than in fiscal 1996.
 
                                      31
<PAGE>
 
  The increase in New York City UBT expense in fiscal 1996 from fiscal 1995
was due to a change in the tax law effective January 1, 1995 imposing taxes on
the total income of Oppenheimer Capital and allowing PIMCO Holdings a credit
for its pro rata share of any New York City UBT paid by Oppenheimer Capital.
Prior to January 1, 1995, New York City UBT was assessed directly at PIMCO
Holdings. A second reason for the increase was Oppenheimer Capital's higher
earnings, including the gain realized on the Quest sale.
 
  A corporate subsidiary of Oppenheimer Capital is subject to federal, state
and local income taxes. A foreign corporate subsidiary is subject to taxes in
the foreign jurisdiction in which it is located.

To the Management Board and Partners of
PIMCO Advisors Holdings L.P.
 
  In our opinion, the accompanying statements of financial condition and the
related statements of operations, of changes in partners' capital and of cash
flows present fairly, in all material respects, the financial condition of
PIMCO Advisors Holdings L.P., formerly Oppenheimer Capital, L.P. (the
"Partnership") at December 31, 1997, April 30, 1997 and April 30, 1996, and
the results of its operations and its cash flows for the eight month period
ended December 31, 1997 and for each of the three years in the period ended
April 30, 1997, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Partnership's
management; our responsibility is to express an opinion on these financial
statements based on our audit. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

                         PIMCO ADVISORS HOLDINGS L.P.
 
                         NOTES TO FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
  PIMCO Advisors Holdings L.P ("PIMCO Holdings") (formerly Oppenheimer
Capital, L.P) is a publicly traded limited partnership owned .01% by its
general partner, PIMCO Partners, G.P. and 99.99% by its public limited
partners ("Unitholders"). PIMCO Holdings' sole business is its ownership of an
approximate 43% interest (approximately 45.5 million GP Units) in PIMCO
Advisors L.P. ("PIMCO Advisors"), a registered investment advisor. PIMCO
Partners, GP and other private holders hold the remaining interest in PIMCO
Advisors. The financial statements of PIMCO Holdings should be read in
conjunction with the consolidated financial statements of PIMCO Advisors.
 
  On November 4, 1997, PIMCO Advisors acquired Oppenheimer Group, Inc.
("Opgroup"), whose subsidiary Oppenheimer Financial Corp. ("Opfin") owned the
32.4% managing general partner interest in Oppenheimer Capital and the one
percent general partner interest in PIMCO Holdings. In the transaction,
Opgroup became a subsidiary of PIMCO Advisors, and the Opgroup stockholders
received 2.1 million PIMCO Advisors Class A units and rights to exchange up to
$230 million of outstanding term notes of Opgroup for an additional 6.9
million PIMCO Advisors Class A units at $33 1/3 per unit. In connection with
the transaction, PIMCO Advisors split the one percent general partner interest
in PIMCO Holdings into a .01% general partner interest and a .99% limited
partner interest, and sold the general partner interest to its general partner
for $80,000, its approximate book value. The purchase method of accounting was
used by PIMCO Advisors to record the acquisition of Opgroup.
 
  On November 30, 1997, Oppenheimer Capital merged with a subsidiary of PIMCO
Advisors, with Oppenheimer Capital surviving (the "OpCap Merger"). In the
OpCap Merger, PIMCO Advisors acquired from PIMCO Holdings its 67.6% general
partner interest in Oppenheimer Capital in exchange for 26.1 million PIMCO
Advisors Class A units, an approximate 24% general partner interest in PIMCO
Advisors. As a result, Oppenheimer Capital became a wholly owned subsidiary of
PIMCO Advisors and the limited partner units of PIMCO Holdings came to
represent an indirect investment in the business of PIMCO Advisors. On
December 1, 1997, PIMCO Holdings effected a 1.67 for 1 split of the PIMCO
Holdings units, so that each PIMCO Holdings unit outstanding after the split
represented an economic interest in one PIMCO Advisors unit. The transaction
was accounted for at book value of PIMCO Advisors, as a transaction between
related parties.
 
  On December 31, 1997, PIMCO Advisors caused its 19.5 million publicly held
units to be contributed to PIMCO Holdings in exchange for an equal number of
PIMCO Holdings units. As a result, PIMCO Advisors ceased to be publicly
traded, and PIMCO Holdings general partner interest in PIMCO Advisors
increased to approximately 43%. Concurrently, PIMCO Holdings New York Stock
Exchange trading symbol was changed from "OCC" to "PA".
 
  Prior to November 4, 1997, PIMCO Holdings was a publicly traded limited
partnership owned 1% by its general partner, Opfin and 99% by its public
limited partners. PIMCO Holdings sole business was its ownership of a 67.6%
interest in Oppenheimer Capital, a registered investment adviser. Opfin held
the remaining 32.4% interest in Oppenheimer Capital.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
  a. FINANCIAL STATEMENT PRESENTATION--Effective December 1, 1997, PIMCO
     Holdings effected a 1.67 for 1 unit split of PIMCO Holdings units. For
     purposes of these financial statements, all units authorized and
     outstanding, and per unit amounts have been restated to reflect the
     split of the PIMCO Holdings units.

                         PIMCO ADVISORS HOLDINGS L.P.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  b. CHANGE OF FISCAL YEAR--Prior to the OpCap Merger, PIMCO Holdings
     reported its results of operations and its financial position based on
     an April 30 fiscal year end. Upon completion of the OpCap Merger, PIMCO
     Holdings changed its fiscal year to a calendar year to correspond with
     that of PIMCO Advisors. Accordingly, the period ending December 31, 1997
     is a "stub" reporting period, eight months in total, consisting of two
     three month periods and one two month period.
 
  c. CASH AND CASH EQUIVALENTS--PIMCO Holdings invests certain cash balances
     in money market funds. At December 31, 1997, this investment is
     approximately $15.5 million which is invested in non affiliate money
     market funds, of which $15.4 million is restricted as a distribution
     payable to holders of PIMCO Holdings units on November 4, 1997, pending
     resolution of certain legal proceedings (see Note 8). At April 30, 1997
     and 1996, this investment was approximately $91 thousand and $35
     thousand, respectively, substantially invested in affiliated money
     market funds. Management considers investments in money market funds to
     be cash equivalents for purposes of the Statements of Cash Flows. These
     investments are carried at cost, which approximates market.
 
  d. INVESTMENT IN PARTNERSHIPS--PIMCO Holdings accounts for its investment
     in PIMCO Advisors (and Oppenheimer Capital prior to November 30, 1997)
     in accordance with the equity method of accounting. PIMCO Holdings
     records as income its proportionate share of the net income of its
     investee partnerships and credits distributions from such partnerships
     to its investment in partnerships. At December 31, 1997, PIMCO Holdings
     had a distribution receivable of $15.2 million from PIMCO Advisors. At
     April 30, 1997 and 1996, PIMCO Holdings had a distribution receivable of
     $17.1 million and $12.0 million, respectively, from Oppenheimer Capital.
 
  e. INCOME TAXES--PIMCO Holdings, as a partnership, generally is not subject
     to federal or state income taxes. However, effective January 1, 1998,
     PIMCO Holdings is subject to a 3.5% federal tax on its gross income from
     active businesses. PIMCO Holdings is subject to an unincorporated
     business tax in a certain jurisdiction in which it operates. All
     partners of PIMCO Holdings are responsible for taxes, if any, on their
     proportionate share of PIMCO Holdings taxable income.
 
  f. NET INCOME PER UNIT--Basic net income per unit is computed based on the
     weighted average number of units outstanding. Diluted net income per
     unit is computed based on the weighted average number of units
     outstanding, assuming the exercise of dilutive unit options. Proceeds
     from the exercise of such unit options are assumed to be used to
     repurchase outstanding limited partner units under the treasury stock
     method. Net income per unit is computed as follows:

  G. OTHER--Certain items have been reclassified to conform with the current
     year presentation.
 
  H. USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS--The
     financial statements have been prepared in accordance with generally
     accepted accounting principles which require management to make
     estimates and assumptions that affect the reported amounts and
     disclosures in the financial statements. Actual results could differ
     from those estimates.
 
3. INTANGIBLE ASSETS
 
  The excess of the initial contributions of capital to Oppenheimer Capital
over the fair value of the net assets acquired had been amortized on a
straight-line basis over a period of 25 years at an annual rate of
approximately $2.6 million. Following the OpCap Merger, this intangible was
eliminated in establishing the investment in PIMCO Advisors.
 
4. SUPPLEMENTARY FINANCIAL DATA
 
  The following table summarizes the unaudited condensed pro forma results of
operations of PIMCO Holdings for the calendar years ended December 31, 1997
and 1996 as if the above acquisition transactions had been completed on
January 1, 1996. The pro forma operating results give effect to:
 
  (i) Conversion of PIMCO Holdings to a calendar year reporting basis;
 
  (ii) The issuance of 2.1 million restricted PIMCO Advisors Class A units in
       connection with the acquisition of the privately held 33% interest in

       Transaction);
 
  (iii) The assumed exchange of $230 million of previously existing
        exchangeable debt for an additional 6.9 million PIMCO Advisors Class
        A units, of which $146.9 million had been exchanged as of December
        31, 1997;
 
  (iv) The contribution of the 67% interest in Oppenheimer Capital by PIMCO
       Holdings for 26.1 million PIMCO Advisors Class A units which occurred
       on November 30, 1997 in the OpCap Merger;
 
  (v) The addition of approximately $897.5 million of intangible assets at
      PIMCO Advisors which arose on November 4, 1997 as result of the Opgroup
      Transaction which will be amortized over 20 years;

        December 31, 1997 rights of PIMCO Advisors Class A units; and

5. NOTE RECEIVABLE
 
  Prior to the OpCap Merger, PIMCO Holdings held a $32.2 million, 10% par
value note due 2012 from Oppenheimer Equities, Inc., a direct wholly owned
subsidiary of Opfin. In connection with the OpCap Merger, this note was repaid
in November 1997.
 
6. BENEFIT PLANS
 
  PIMCO Advisors and PIMCO Holdings jointly adopted the 1997 Unit Incentive
Plan (the "1997 Plan") effective January 1, 1998. The 1997 Plan is intended to
further the financial success of PIMCO Holdings and PIMCO Advisors through
obtaining and retaining the services of members of their respective management
boards, key employees and consultants who will contribute to their growth,
development and financial success, by offering such members, key employees and
consultants the opportunity to own, or have the right to share in the
appreciation of, PIMCO Holdings units, and, if they are "qualified persons"
within the meaning of 1997 Plan, PIMCO Advisors units. The 1997 Plan is
currently administered by the Management Board of PIMCO Holdings and the Unit
Incentive Committee of the Management Board of PIMCO Advisors. The aggregate
number of PIMCO Holdings and PIMCO Advisors units that may be issued upon
exercise of awards under the 1997 Plan may not exceed 30 million. Pursuant to
an arrangement between PIMCO Advisors and PIMCO Holdings, PIMCO Advisors will
issue to PIMCO Holdings a number of PIMCO Advisors units equal to the number
of PIMCO Holdings units issued under the 1997 Plan.
 
  Concurrent with the effective date of the 1997 Plan, awards for an aggregate
of 12,525,069 Partnership Units (including 3,203,850 restricted unit rights)
granted under plans sponsored by PIMCO Advisors and Oppenheimer Capital were
assumed under the 1997 Plan. In this regard, each option outstanding under the
1993 Unit Option Plan of PIMCO Advisors L.P. (the "1993 Plan") was, to the
extent the holder consented thereto,

replaced by an option granted under the 1997 Plan, each option outstanding
under the 1996 Unit Incentive Plan of PIMCO Advisors L.P. (the "1996 Plan")
was replaced by an option granted under the 1997 Plan, each option outstanding
under the Oppenheimer Capital Amended and Restated Restricted Option Plan (the
"OpCap Option Plan") was replaced by an option granted under the 1997 Plan and
each right to receive PIMCO Holdings units outstanding under the Oppenheimer
Capital Amended and Restricted Unit Plan ("OpCap Rights Plan") was replaced by
an award of deferred units under the 1997 Plan. Each such award covered the
same number of limited partnership units and had the same term and vesting
schedule as the award which it replaced.
 
  The 1997 Plan, and the awards thereunder other than those assumed from
previously existing PIMCO Advisors and Oppenheimer Capital plans, are subject
to the approval of the unitholders of PIMCO Holdings.
 
  Prior to effectiveness of the 1997 Plan, PIMCO Holdings and Oppenheimer
Capital maintained the OpCap Option Plan and the OpCap Rights Plan for the
benefit of certain key employees. Pursuant to these plans, an eligible
employee was granted the right to receive a number of units of PIMCO Holdings
at no cost to the employee ("Rights"), in the case of the OpCap Rights Plan,
and/or the right to purchase a number of units at the fair market value of
such units on the date of grant ("Options"), in the case of the OpCap Option
Plan. The right to receive or purchase units vests 33 1/3% per year at the end
of each of the third, fourth and fifth years from the date of grant. PIMCO
Holdings transferred to Oppenheimer Capital the proceeds from the exercise of
Options in exchange for an increase in its general partner interest in
Oppenheimer Capital. Opfin and the limited partners of PIMCO Holdings incurred
dilution, in accordance with their respective percentage interest in
Oppenheimer Capital, upon the vesting of Rights and the exercise of Options.
 
  No compensation cost is recognized in the statements of income by
Oppenheimer Capital for the Options granted under the OpCap Option Plan
because the exercise price of the Options approximates the market price of the
units on the date of the grant. For the same reason no compensation cost is
recognized in the statements of operations of PIMCO Advisors for its fixed
unit option plans. Had compensation cost been recognized based on the fair
value of the awards at the date of grant, PIMCO Holdings net income would have
been reported as the pro forma amounts indicated below:

pricing model with the following weighted average assumptions used for the
grants in the eight months ended December 31, 1997, fiscal 1997 and fiscal
1996, respectively: 1) For the OpCap Option Plan--distribution yield of 5.8%,
7.3% and 8.0%; expected volatility of 19%, 21% and 22%; risk free interest
rate of 6.62%, 6.36% and 6.96%; and expected lives of 6, 6 and 7 years; 2) For
the 1997 Plan--distribution yield of 7.3%, 7.7% and 3.5%; expected volatility
of 21%, 14% and 10%; risk free interest rate of 6.52%, 6.30% and 6.80%; and
expected lives of 5, 6 and 7 years.

7. GAIN ON QUEST SALE
 
  Included in "Equity in earnings of partnerships" for the fiscal years ended
April 30, 1997 and 1996 are gains resulting from Oppenheimer Capital's sale of
the investment advisory and other contracts and business relationships for its
twelve Quest for Value mutual funds to OppenheimerFunds, Inc. ("OFI"), which
is unrelated to Oppenheimer Capital. For the years ended April 30, 1997 and
1996, PIMCO Holdings recognized gains of $1.8 million, or $.07 per unit, and
$17.7 million, or $.69 per unit, respectively.
 
  The Quest for Value Dual Purpose Fund was sold to OFI in July 1997, and
PIMCO Holdings recognized a gain on the sale of $2.8 million, or $.11 per
unit.
 
8. LEGAL PROCEEDINGS
 
  On November 30, 1997, Richard Buzby filed an action on behalf of a purported
class of limited partners of PIMCO Holdings against PIMCO Advisors and certain
individuals associated with the previous general partner of PIMCO Holdings in
the Court of Chancery of the State of Delaware, New Castle County. The
complaint alleges, among other things, various breaches of fiduciary duty,
conflicts of interest and unfair dealing in connection with the OpCap Merger.
The complaint seeks compensatory and/or recissionary money damages or,
alternatively, injunctive relief or recission of the transactions. Since that
date, certain other complaints have been filed in the states of Delaware and
New York, making similar allegations. These cases were consolidated in the
Court of Chancery of the State of Delaware, New Castle County.
 
  A tentative settlement has been reached, pending approval of the court,
wherein $15.4 million, less court and attorney costs, will be distributed to
the class. As of December 31, 1997, this amount has been funded to a
segregated cash account, and is included in other current liabilities.

To the Management Board and Partners of PIMCO Advisors L.P.
 
  In our opinion, the accompanying consolidated statement of financial
condition and the related consolidated statements of operations, of changes in
partners' capital and of cash flows present fairly, in all material respects,
the financial position of PIMCO Advisors L.P. and Subsidiaries (the
"Partnership") at December 31, 1997 and 1996, and the results of their
operations and their cash flows for the years then ended, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Partnership's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.

                     PIMCO ADVISORS L.P. AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
  PIMCO Advisors L.P. ("PIMCO Advisors") is an investment management firm
providing fixed income and equity investment management to institutional and
retail clients, offering the investment management expertise, performance
record and reputations of its institutional investment managers, which include
the fixed income oriented Pacific Investment Management Company ("Pacific
Investment Management") and the equity oriented Oppenheimer Capital. PIMCO
Advisors operates in one industry segment--investment management services.
 
  PIMCO Advisors offers its investment management services to institutional
clients through client service representatives of its investment management
groups. Institutional clients invest through separate accounts and pooled
vehicles such as the institutional share classes of the PIMCO Funds, PIMCO
Advisors' family of 45 proprietary mutual funds. PIMCO Advisors offers the
investment expertise of its institutional investment managers to retail
investors through the retail share classes of the PIMCO Funds, which are
distributed primarily through broker dealers including PIMCO Funds
Distributors LLC ("PFD", formerly known as PIMCO Funds Distribution Company),
a wholly-owned broker-dealer which distributes and markets shares of the
retail mutual funds of PIMCO Advisors.
 
  PIMCO Advisors and its subsidiaries were formed on November 15, 1994, when
Pacific Asset Management LLC (a subsidiary of Pacific Life Insurance Company)
merged certain of its investment management businesses and substantially all
of its assets (the "PFAMCo Group") into Thomson Advisory Group L.P. ("TAG LP")
(the "Consolidation").
 
  On November 4, 1997, PIMCO Advisors acquired Oppenheimer Group, Inc.
("Opgroup"), whose subsidiary Oppenheimer Financial Corp. ("Opfin") owned the
32.4% managing general partner interest in Oppenheimer Capital and the one
percent general partner interest in PIMCO Advisors Holdings L.P. (formerly
Oppenheimer Capital, L.P.) ("PIMCO Holdings"). In the transaction, Opgroup
became a subsidiary of PIMCO Advisors, and the Opgroup stockholders received
2.1 million PIMCO Advisors Class A units and rights to exchange up to $230
million of outstanding term notes of Opgroup for an additional 6.9 million
PIMCO Advisors Class A units at $33 1/3 per unit. In connection with the
transaction, PIMCO Advisors split the one percent general partner interest in
PIMCO Holdings into a .01% general partner interest and a .99% limited partner
interest, and sold the general partner interest to its general partner for
$80,000, its approximate book value. As explained further in Note 3, the
purchase method of accounting was used by PIMCO Advisors to record the
acquisition of Opgroup.
 
  On November 30, 1997, Oppenheimer Capital merged with a subsidiary of PIMCO
Advisors, with Oppenheimer Capital surviving (the "OpCap Merger"). In the
OpCap Merger, PIMCO Advisors acquired from PIMCO Holdings its 67.6% general
partner interest in Oppenheimer Capital in exchange for 26.1 million PIMCO
Advisors Class A units, an approximate 24% general partner interest in PIMCO
Advisors. As a result, Oppenheimer Capital became a wholly owned subsidiary of
PIMCO Advisors and the limited partner units of PIMCO Holdings came to
represent an indirect investment in the business of PIMCO Advisors. As a
result, the consolidated statement of operations includes the operations of
Oppenheimer Capital since November 4, 1997, also reflecting a minority
interest expense of $2.4 million for the month of November, included in other
income, net. The transaction was accounted for at book value of PIMCO
Advisors, as a transaction between related parties.
 
  On December 31, 1997, PIMCO Advisors caused its 19.5 million publicly held
units to be contributed to PIMCO Holdings in exchange for an equal number of
PIMCO Holdings units. As a result, PIMCO Advisors ceased to be publicly
traded, and PIMCO Holdings general partner interest in PIMCO Advisors
increased to approximately 43%. Concurrently, PIMCO Holdings New York Stock
Exchange trading symbol was changed from "OCC" to "PA".

                     PIMCO ADVISORS L.P. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Prior to January 17, 1997, institutional mutual funds managed consisted of
two open-end investment management companies. One series is predominantly
fixed income funds. The other series is predominantly equity funds. The retail
mutual funds managed were included within two open-end investment management
companies, the PIMCO Advisors Funds ("PAF"), formerly the Thomson Funds, and
the Cash Accumulation Trust ("CAT"). With Trustee and shareholder approval,
the fund groups (excluding CAT) were combined into a single mutual fund
complex, the PIMCO Funds ("Proprietary Funds"), in January 1997, consisting of
45 funds offering retail and institutional share classes as of December 31,
1997.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
  a. CASH AND CASH EQUIVALENTS--PIMCO Advisors invests certain cash balances
     in money market funds. At December 31, 1997, this investment is
     approximately $28,949,000, of which approximately $330,000 is invested
     in the National Money Market Fund of CAT, approximately $627,000 is
     invested in the PIMCO Advisors Money Market Fund, approximately
     $3,528,000 is invested in the OCC Cash Reserves Primary Portfolio and
     approximately $24,464,000 is invested in non affiliate money market
     funds. At December 31, 1996, this investment was approximately
     $25,429,000, of which approximately $814,000 was invested in the
     National Money Market Fund of CAT, approximately $595,000 was invested
     in the PIMCO Advisors Money Market Fund and approximately $24,020,000
     was invested in non affiliate money market funds. Management considers
     investments in money market funds to be cash equivalents for purposes of
     the Consolidated Statements of Cash Flows. These investments are carried
     at cost, which approximates market.
 
  b. INVESTMENT ADVISORY FEES--PIMCO Advisors records investment advisory
     fees on an accrual basis. Investment advisory fees receivable for
     private and separate accounts consist primarily of accounts billed on a
     quarterly basis. Private accounts may also generate a fee based on
     investment performance, which is recorded as income when earned and not
     subject to forfeiture. Investment advisory fees for the Proprietary
     Funds are received monthly.
 
  c. SHORT-TERM INVESTMENTS--The short term investments, as of December 31,
     1997 and 1996, are primarily invested in the PIMCO Funds with a short-
     term duration objective. The investments are carried at market value.
     Cost approximated market value as of December 31, 1997 and 1996.
 
  d. DEPRECIATION AND AMORTIZATION--Office equipment, furniture and fixtures
     are depreciated on a straight line basis over their estimated useful
     lives, generally five years. Automobiles are depreciated on a straight-
     line basis over their estimated lives, generally three years. Leasehold
     improvements are amortized on a straight-line basis over the remaining
     terms of the related leases or the useful lives of such improvements,
     whichever is shorter.
 
  e. OTHER ASSETS--Effective May 29, 1995, PFD commenced sale of a "B" class
     of mutual fund shares. Under this share structure PFD advances
     commissions to independent brokers and is entitled to recoup its
     marketing costs through an ongoing fee stream from the respective funds
     or through contingent deferred sales charges collected from the share
     purchaser. Such fees are capitalized as deferred sales charges and
     amortized on a straight line basis as commission expense over a period
     of 60 months. Deferred unamortized marketing costs of approximately
     $22,700,000 and $11,100,000 are included in other non current assets at
     December 31, 1997 and 1996, respectively.
 
  f. INCOME TAXES--Subsequent to the Consolidation, PIMCO Advisors and its
     subsidiaries are predominantly partnerships and, as a result, are
     generally not subject to federal or state income taxes. PIMCO Advisors
     is subject to an unincorporated business tax in a certain jurisdiction
     in which it operates. All partners of PIMCO Advisors are responsible for
     taxes, if any, on their proportionate share of PIMCO Advisors' taxable
     income. Certain corporate subsidiaries are subject to federal and state
     income taxes and file separate tax returns. The provision for income
     taxes is determined using the
 
                                      55

     liability method which gives recognition to deferred tax assets and
     liabilities based on the expected future tax consequences of events that
     have been recognized in the financial statements or tax returns.
 
  g. FOREIGN CURRENCY TRANSLATION--The assets and liabilities of Blairlogie
     have been translated into U.S. dollars at the current rate of exchange
     existing at year-end. Revenues and expenses were translated at the
     average of the monthly exchange rates then in effect.
 
  h. NET INCOME ALLOCATION--Net income is allocated in accordance with the
     Amended and Restated Agreement of Limited Partnership of PIMCO Advisors.
     Net income is allocated among unit holders in the same proportions as
     cash distributions. For each of the periods presented, PIMCO Advisors
     cash distribution policy provided for a first priority distribution to
     General Partner and Class A Limited Partner units ($1.88 per year
     through December 31, 1997) followed by a second priority distribution to
     Class B Limited Partner units. During the years ended December 31, 1996
     and 1995, the second priority distribution was less than the first
     priority distribution. For the year ended December 31, 1997, the
     distribution was equal for all classes of units. The Class A unit
     distribution preference will end with the payment of the distribution
     for the fourth quarter of 1997, and on March 1, 1998, all PIMCO Advisors
     Class B units will be converted into Class A units.
 
  i. NET INCOME PER UNIT--Basic net income per unit is computed based on the
     weighted average number of units outstanding. Diluted net income per
     unit assumes the exercise of dilutive unit options. Proceeds from the
     exercise of such unit options are assumed to be used to repurchase
     outstanding limited partner units under the treasury stock method. The
     weighted average number of units used to compute basic and diluted net
     income per unit was as follows:

  j. OTHER--Certain items have been reclassified to conform with the current
     year presentation. All significant intercompany items have been
     eliminated in the accompanying consolidated financial statements.
 
  k. USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS--The
     financial statements have been prepared in accordance with generally
     accepted accounting principles which require management to make
     estimates and assumptions that affect the reported amounts and
     disclosures in the financial statements. Actual results could differ
     from those estimates.
 
3. INTANGIBLE ASSETS
 
  The acquisition of Opgroup in November 1997 has been recorded under the
purchase accounting method. Intangible assets of approximately $897.5 million
represented the excess of the purchase price over the fair value of the net
tangible assets of Oppenheimer Capital acquired. This amount will be amortized
on a straight line basis over 20 years. For accounting purposes, the
Consolidation between PFAMCo Group and TAG LP in 1994 was treated as a
purchase and recapitalization of TAG LP by PFAMCo Group, or a "reverse
acquisition." Intangible assets of approximately $284.9 million represented
the excess of the purchase price over the fair value of the net tangible
assets of TAG LP deemed acquired in the Consolidation. A portion of these
intangible assets represents the value assigned to PIMCO Advisors Master
Limited Partnership ("MLP") structure. Under prior Internal Revenue Code
guidelines, an MLP was exempt from federal and most state and local income
taxes through December 31, 1997. The value attributed to the MLP structure has
been amortized over the period ending December 31, 1997. The remainder is
amortized on a straight-line basis over its estimated life of 20 years.

8. BENEFIT PLANS
 
  a. PROFIT SHARING AND INCENTIVE PROGRAMS--PIMCO Advisors and its
     subsidiaries have several profit sharing and incentive programs that
     compensate participants on the basis of profitability and discretionary
     bonuses. Compensation under these programs was approximately $152.9
     million, $114.1 million, and $94.5 million for the years ended December
     31, 1997, 1996 and 1995, respectively.
 
  b. EXECUTIVE DEFERRED COMPENSATION PLAN--PIMCO Advisors and its
     subsidiaries have a nonqualified deferred compensation plan pursuant to
     which a portion of the compensation otherwise payable to certain
     eligible employees will be mandatorily deferred, and pursuant to which
     such eligible employees may elect to defer additional amounts of
     compensation. The plan is unfunded and is maintained primarily for the
     purpose of providing deferred compensation for a select group of
     management or
 
                                      58

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
     highly compensated employees, within the meaning of Sections 201(2),
     301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act
     of 1974, as amended. Amounts deferred under the plan are used to acquire
     units of PIMCO Advisors and are held in the trust for the employees. As
     of December 31, 1997 and 1996, the balance related to PIMCO Advisors and
     its subsidiaries in the trust and the related deferred compensation
     obligations was approximately $15.1 million and $1.0 million,
     respectively.
 
  c. SAVINGS AND INVESTMENT PLANS--PIMCO Advisors and its subsidiaries have
     several defined contribution employee benefit plans covering
     substantially all employees. PIMCO Advisors and Pacific Investment
     Management are the sponsors of certain defined contribution employee
     savings and investment plans. The plans qualify under Section 401(k) of
     the Internal Revenue Code and allow eligible employees of PIMCO Advisors
     and certain of its subsidiaries, to contribute up to ten percent of
     their annual compensation as defined, and subject to a maximum dollar
     amount determined from time to time under the provisions of the Internal
     Revenue Code. Employees are generally eligible following the later of
     attainment of age 21 or the completion of one year of credited service.
     For 1997, 1996 and 1995, PIMCO Advisors and certain of its subsidiaries
     matched and contributed an amount up to the first six percent of annual
     compensation, subject to Internal Revenue Code limits, contributed by
     the employees. In addition, PIMCO Advisors and certain of its
     subsidiaries, may elect to make a discretionary contribution to all
     participants. The amount expensed by PIMCO Advisors and its subsidiaries
     related to these plans during the year ended December 31, 1997, 1996 and
     1995 was approximately $2.2 million, $2.0 million and $1.9 million,
     respectively.
 
       Pacific Investment Management has several defined contribution
     employee benefit plans covering substantially all of its employees and
     made contributions to the plans ranging from five percent to eleven
     percent of covered individuals' base compensation. The aggregate expense
     recorded is approximately $1.1 million, $.9 million and $1.0 million in
     1997, 1996 and 1995, respectively.
 
  d. UNIT BASED INCENTIVE PLANS--PIMCO Advisors and PIMCO Holdings jointly
     adopted the 1997 Unit Incentive Plan (the "1997 Plan") effective January
     1, 1998. The 1997 Plan is intended to further the financial success of
     PIMCO Holdings and PIMCO Advisors through obtaining and retaining the
     services of members of their respective management boards, key employees
     and consultants who will contribute to their growth, development and
     financial success, by offering such members, key employees and
     consultants the opportunity to own, or have the right to share in the
     appreciation of, PIMCO Holdings units, and, if they are "qualified
     persons" within the meaning of 1997 Plan, PIMCO Advisors units. The 1997
     Plan is currently administered by the Management Board of PIMCO Holdings
     and the Unit Incentive Committee of the Management Board of PIMCO
     Advisors. The aggregate number of PIMCO Holdings and PIMCO Advisors
     units that may be issued upon exercise of awards under the 1997 Plan may
     not exceed 30 million. Pursuant to an arrangement between PIMCO Advisors
     and PIMCO Holdings, PIMCO Advisors will issue to PIMCO Holdings a number
     of PIMCO Advisors units equal to the number of PIMCO Holdings units
     issued under the 1997 Plan.
 
       Concurrent with the effective date of the 1997 Plan, awards granted
     under plans sponsored by PIMCO Advisors and Oppenheimer Capital were
     assumed under the 1997 Plan. In this regard, each option outstanding
     under the 1993 Unit Option Plan of PIMCO Advisors L.P. (the "1993 Plan")
     was, to the extent the holder consented thereto, replaced by an option
     granted under the 1997 Plan, each option outstanding under the 1996 Unit
     Incentive Plan of PIMCO Advisors L.P. (the "1996 Plan") was replaced by
     an option granted under the 1997 Plan, each option outstanding under the
     Oppenheimer Capital Amended and Restated Restricted Option Plan (the
     "OpCap Option Plan") was replaced by an option granted under the 1997
     Plan and each right to receive PIMCO Holdings units

                     PIMCO ADVISORS L.P. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
    outstanding under the Oppenheimer Capital Amended and Restricted Unit
    Plan ("OpCap Rights Plan") was replaced by an award of deferred units
    under the 1997 Plan. Each such award covered the same number of limited
    partnership units and had the same term and vesting schedule as the
    award which it replaced.
 
      The 1997 Plan, and the awards thereunder other than those assumed
    from previously existing PIMCO Advisors and Oppenheimer Capital plans,
    are subject to the approval of the unitholders of PIMCO Holdings.
 
      Prior to the adoption of the 1997 Plan, PIMCO Advisors maintained a
    restricted unit plan and two unit options plans for the benefit of
    certain key employees. A total of 150,000 Class A limited partner units
    and 150,000 Class B limited partner units have been awarded under the
    plan. In addition, under the OpCap Rights Plan, approximately 2,177,000
    Class A limited partner deferred units were awarded. Under these plans,
    units generally vest over a five-year period; however, accelerated
    vesting occurred in 1995 upon the departure of a key employee. The
    expense under these plans was approximately $3.8 million, $.8 million
    and $2.0 million during 1997, 1996 and 1995, respectively.
 
      In addition, PIMCO Advisors maintained two unit-option plans, which
    are described below. No compensation cost is recognized for these fixed
    unit option plans where the option price approximated the market price
    on the date of grant. Had compensation cost for PIMCO Advisors two unit
    option plans been determined based on the fair value at the grant
    dates, PIMCO Advisors net income and earnings per unit would have been
    reported as the pro forma amounts indicated below:

      For the above disclosure purposes, the fair value of each option
    granted is estimated on the date of grant using the Black-Scholes
    option-pricing model with the following weighted-average assumptions
    used for grants in 1997, 1996 and 1995, respectively: dividend yield of
    7.3%, 7.7% and 3.5%; expected volatility of 21%, 14% and 10%; risk-free
    interest of 6.52%, 6.30% and 6.80%; and expected lives of 5, 6 and 7
    years, respectively.
 
      The unit option plans were administered by the Unit Incentive
    Committee of the Management Board of PIMCO Advisors, which determines
    the key employees and the terms of the options to be granted. Under the
    1993 Plan, PIMCO Advisors could grant options to its employees for up
    to 3,090,000 Class A units. Under the 1996 Plan, PIMCO Advisors could
    grant options to its employees for up to 10,000,000 Class B units. At
    December 31, 1997, there were 3,933,133 Class B Limited Partner unit
    options available for future grants. The expense under the option plans
    was approximately
 
                                      60

    $4.4 million, $4.4 million and $4.7 million during 1997, 1996 and 1995,
    respectively. Under the 1996 Plan, the exercise price for each option
    reported herein has not been less than the average trading price of
    PIMCO Advisors units for the 20 trading day period prior to the grant
    date and each option's maximum term is 10 years. There was no material
    difference between the option price and the market price on the grant
    date. The outstanding options vest over a period of not more than five
    years and vested options are generally exercisable after January 1,
    1998. As noted above, effective January 1, 1998, all such awards, and
    those under the OpCap Option Plan and OpCap Rights Plan, were assumed
    under the 1997 Plan. Following is a summary of the status of the awards
    under the unit option plans:

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
 
To The General Partners of
Oppenheimer Capital
 
  In our opinion, the accompanying consolidated statements of financial
condition and the related consolidated statements of operations, changes in
partners' capital and cash flows present fairly, in all material respects, the
financial position of Oppenheimer Capital and its subsidiaries (the
"Partnership") at December 31, 1997 and April 30, 1997 and 1996, and the
results of their operations and their cash flows for the eight month period
ended December 31, 1997 and for each of the three years in the period ended
April 30, 1997, in conformity with generally accepted accounting principles.
These consolidated financial statements are the responsibility of the
Partnership's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

     (formerly AMA Investment Advisers, L.P.) (collectively, the
     "Subpartnerships"), Oppenheimer Capital Limited and Oppenheimer Capital
     Trust Company. All material intercompany balances and transactions have
     been eliminated in consolidation.
 
  b. CASH AND SHORT TERM INVESTMENTS--Short term investments are recorded at
     cost, which approximates market value, and include holdings in money
     market mutual funds and highly-liquid investments with maturities of
     three months or less.
 
  c. FURNITURE, EQUIPMENT AND LEASEHOLD IMPROVEMENTS--Furniture and equipment
     are depreciated on a straight-line basis over five to seven year
     periods. Amortization of leasehold improvements is on a straight-line
     basis over the lesser of their economic useful life or the term of the
     lease.
 
  d. INVESTMENT MANAGEMENT FEES--Investment management fees are based on
     written contracts and are generally computed on the net assets of the
     managed accounts and recognized in the period earned.
 
  e. STATEMENTS OF CASH FLOWS--For purposes of reporting cash flows, cash and
     short term investments include highly liquid investments with maturities
     of three months or less.
 
  f. INTANGIBLE ASSETS--Impairment of intangible assets is measured on the
     basis of anticipated undiscounted cash flows. At December 31, 1997 and
     April 30, 1997, 1996 and 1995, Oppenheimer Capital determined that there
     was no impairment of intangible assets.
 
  g. USE OF ESTIMATES--The preparation of financial statements in conformity
     with generally accepted accounting principles requires management to
     make estimates and assumptions that affect the reported amounts of
     assets and liabilities and disclosure of contingent assets and
     liabilities at the date of the financial statements and the reported
     amounts of revenues and expenses during the reporting periods. Actual
     results could differ from those estimates.
 
2. SALE OF OPFIN INTEREST
 
  On November 4, 1997, PIMCO Advisors acquired Oppenheimer Group, Inc.
("Opgroup"), whose subsidiary Oppenheimer Financial Corp. ("Opfin") owned the
32.4% managing general partner interest in Oppenheimer Capital and the one
percent general partner interest in PIMCO Holdings L.P. ("PIMCO Holdings")
(formerly, Oppenheimer Capital, L.P.). In the transaction, Opgroup became a
subsidiary of PIMCO Advisors, and the Opgroup stockholders received 2.1
million PIMCO Advisors Class A units and rights to exchange up to $230 million
of outstanding term notes of Opgroup for an additional 6.9 million PIMCO
Advisors Class A units at $33 1/3 per unit. In connection with the
transaction, PIMCO Advisors split the one percent general partner interest in
PIMCO Holdings into a .01% general partner interest and a .99% limited partner
interest, and sold the general partner interest to its general partner for
$80,000, its approximate book value. The purchase method of accounting was
used by PIMCO Advisors to record the acquisition of Opgroup.
 
  On November 30, 1997, Oppenheimer Capital merged with a subsidiary of PIMCO
Advisors, with Oppenheimer Capital surviving (the "OpCap Merger"). In the
OpCap Merger, PIMCO Advisors acquired from

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
PIMCO Holdings its 67.6% general partner interest in Oppenheimer Capital in
exchange for 26.1 million PIMCO Advisors Class A units, an approximate 24%
general partner interest in PIMCO Advisors. As a result, Oppenheimer Capital
became a wholly owned subsidiary of PIMCO Advisors and the limited partner
units of PIMCO Holdings came to represent an indirect investment in the
business of PIMCO Advisors. The transaction was accounted for at book value of
PIMCO Advisors, as a transaction between related parties.
 
  On December 31, 1997, PIMCO Advisors caused its 19.5 million publicly held
units to be contributed to PIMCO Holdings in exchange for an equal number of
PIMCO Holdings units. As a result, PIMCO Advisors ceased to be publicly
traded, and PIMCO Holdings general partner interest in PIMCO Advisors
increased to approximately 43%. Concurrently, PIMCO Holdings New York Stock
Exchange trading symbol was changed from "OCC" to "PA".
 
3. LONG TERM LEASE COMMITMENTS
 
  Oppenheimer Capital occupies office premises at various locations, including
the Oppenheimer Tower under an agreement to sublease with CIBC Oppenheimer
Corp., ("Opco"), a broker-dealer which was affiliated with Oppenheimer Capital
until November 4, 1997. Oppenheimer Capital's lease commitments for office
space under operating leases having noncancelable lease terms in excess of one
year provide for the following minimum annual rentals:

ended April 30, 1997, 1996 and 1995 was $5,046,000, $5,348,000 and $5,100,000,
respectively.
 
4. COMPENSATION PLANS
 
  Oppenheimer Capital has established a Restricted Unit Plan and a Restricted
Option Plan (the "OpCap Plans") for the benefit of certain key employees.
Pursuant to the OpCap Plans, an eligible employee is granted the right to
receive a number of units of PIMCO Holdings or, in certain cases after
December 31, 1997, PIMCO Advisors, at no cost to the employee ("Rights"), in
the case of the Restricted Unit Plan, and/or the right to purchase a number of
units at the fair market value of such units on the date of grant ("Options"),
in the case of the Restricted Option Plan. Obligations under the OpCap Plans
have been assumed by PIMCO Advisors and PIMCO Holdings effective January 1,
1998. The right to receive or purchase units vests 33 1/3% per year at the end
of each of the third, fourth and fifth years from the date of grant. A total
of 6,304,250 restricted units and/or restricted options have been authorized
under the OpCap Plans. The following table shows the Rights granted and the
Options granted with exercise prices of $12.35 to $21.63 (all reflective of a
1.67 for 1 split effective December 1, 1997) at December 31, 1997. As a result
of the grant of Rights, Oppenheimer Capital recorded

$8,574,000 for the eight month period ended December 31, 1997 and $5,977,000,
$4,738,000 and $343,000 for the fiscal years ended April 30, 1997, 1996 and
1995, respectively, which amounts are amortized over a five year period. In
addition, approximately $67.8 million was recorded as deferred compensation
expense in partners' capital of PIMCO Advisors for special grants made in
November of 1997 associated with the completion of sale of the Opfin interest.
Amortization of $2,677,000 for the eight month period ended December 31, 1997
and $2,209,000, $1,691,000, and $1,280,000 for the fiscal years ended April
30, 1997, 1996 and 1995, respectively, has been recorded. This amortization
results in a charge to compensation and benefits and a corresponding credit to
partners' capital.

  No compensation cost is recognized in the consolidated statements of
operations for Options granted under the OpCap Plans because the exercise
price of the Options approximates the market price of the units on the date of
grant. Had compensation cost for the Options been recognized based on the fair
value of the Options at the date of the grant, Oppenheimer Capital's net
income would have been reported as the pro forma amounts indicated below:

  Biographical information with respect to the above-listed individuals is set
forth below. Because the sole business of PIMCO Holdings is that of owning
PIMCO Advisors units, information relating to the management of PIMCO Advisors
is set forth below.
 
MANAGEMENT OF PIMCO ADVISORS
 
  PIMCO Advisors is managed by its general partners, PGP and PIMCO Holdings.
PGP has direct control of PIMCO Holdings, and therefore controls PIMCO
Advisors. The general partners have the equal right, power and authority to
manage and control the business and affairs of PIMCO Advisors and, except as
otherwise provided in the PIMCO Advisors Partnership Agreement, may take any
action deemed necessary or desirable by them in connection with the business
of PIMCO Advisors. Any difference arising as to any action connected with the
business of PIMCO Advisors, other than those requiring the unanimous consent
of the general partners, is decided by the general partners holding a majority
of the outstanding general partner units.
 
  While the general partners must pursuant to the PIMCO Advisors Partnership
Agreement retain and exercise certain powers, generally relating to
extraordinary transactions or events, the general partners have delegated all
other management and control of PIMCO Advisors to a 16 member management board
(the "PIMCO Advisors Management Board"), comprised of the Chief Executive
Officer of PIMCO Advisors, representatives of the general partners,
representatives of the investment management subsidiaries, and three
"disinterested" members not otherwise affiliated with PIMCO Advisors or the
general partners. The PIMCO Advisors Management Board generally acts by
majority vote, however, certain significant actions require a three-quarters
majority vote. The delegation to the PIMCO Advisors Management Board may be
revoked by the general partners (by PGP as the controlling general partner) at
any time.
 
  The PIMCO Advisors Management Board has, in turn, constituted a five member
Executive Committee and delegated to it much of the functions of the PIMCO
Advisors Management Board. In addition, PIMCO Advisors has an Audit Committee,
a Compensation Committee, a Nominating Committee and a Unit Incentive
Committee, each comprised of members of the PIMCO Advisors Management Board.

  The members of the PIMCO Advisors Management Board, the Executive Committee
and the executive officers of PIMCO Advisors are as set forth below. The
initial terms of all PIMCO Advisors Management Board members expire on April
30, 1999. PIMCO Advisors Management Board members thereafter will be appointed
to one year terms.

COMPENSATION OF BOARD MEMBERS
 
  PIMCO Advisors pays members of the PIMCO Advisors Management Board who are
not employees of PIMCO Holdings, PIMCO Advisors, one of the investment
management group subsidiaries or Pacific Life Insurance Company a $20,000
annual retainer plus $750 per in-person meeting ($250 per conference call
meeting) of the Management Board attended and for each meeting of a committee
of the Management Board. Members who are employees of PIMCO Holdings, PIMCO
Advisors, one of its investment management group subsidiaries or Pacific Life
Insurance Company are not entitled to any additional compensation for their
services as Management Board members. Pursuant to the terms of the 1997 Plan,
the non-employee members of the Management Board may elect to receive
restricted PIMCO Holdings units or PIMCO Advisor Units in lieu of such
retainer, with such restricted units valued at 91% of fair market value on the
date of issuance.
 
COMPENSATION OF GENERAL PARTNER
 
  The general partners of PIMCO Holdings and PIMCO Advisors receive no
compensation from PIMCO Holdings or PIMCO Advisors for services rendered to
PIMCO Holdings or PIMCO Advisors as a general partner. Rather, the general
partners' interests in profits and losses of PIMCO Holdings and PIMCO Advisors
are based on their interest in PIMCO Holdings and PIMCO Advisors,
respectively. Upon liquidation, the liquidating distributions to the general
partners will be based on the number of PIMCO Holdings units and PIMCO
Advisors units each holds. Each general partner is reimbursed for all direct
expenses paid by it on behalf
 
                                      80
<PAGE>
 
of PIMCO Advisors, for all expenses incurred by it in connection with the
business and affairs of PIMCO Advisors and, in the case of a Public General
Partner (as defined in the PIMCO Advisors Partnership Agreement), for all
expenses (other than taxes) of the Public General Partner. PIMCO Holdings is a
Public General Partner and, therefore, all of its expenses (other than taxes)
are paid by PIMCO Advisors.
 
COMPENSATION PURSUANT TO CONTRACT
 
  William D. Cvengros, the Chief Executive Officer of PIMCO Holdings and PIMCO
Advisors and a member of the PIMCO Advisors Management Board and the Executive
Committee, is party to an employment agreement with PIMCO Advisors, the term
of which was extended through December 31, 1998 by the Management Board of
PIMCO Advisors in January 1997. Under the agreement, Mr. Cvengros receives an
annual base salary of $500,000 and a guaranteed annual bonus of $500,000. Mr.
Cvengros is also eligible to receive a discretionary bonus in the target range
of $200,000 to $500,000 (which amount may be increased or decreased upon the
recommendation of the Executive Committee and the approval of the PIMCO
Advisors Management Board). PIMCO Advisors granted Mr. Cvengros options to
purchase up to 400,000 PIMCO Advisors units under the PIMCO Advisors 1994 Unit
Option Plan. In 1994, Mr. Cvengros was also granted 200,000 restricted
PIMCO Advisors units which are forfeitable to PGP upon certain events of
termination. If his contract is terminated without cause between December 31,
1996 and December 31, 1998, he is entitled to accrued and unpaid salary and
bonus payments totaling $500,000 and immediate vesting of all of his options
and restricted units.
 
  Kenneth M. Poovey, Chief Operating Officer of PIMCO Holdings and PIMCO
Advisors, and PIMCO Advisors have agreed to a compensation arrangement,
pursuant to which Mr. Poovey receives an annual base salary of $300,000. Mr.
Poovey is also eligible to receive a bonus in the target range of $300,000 to
$900,000. In May 1997, PIMCO Advisors granted Mr. Poovey 25,000 restricted
PIMCO Advisors units vesting over a three year period, and Mr. Poovey is
eligible, based on performance, for a second grant of up to 25,000 restricted
PIMCO Advisors units in the first quarter of 1998, which will also vest over a
three year period. PIMCO Advisors granted Mr. Poovey options to purchase up to
50,000 PIMCO Advisors units, which will vest over a period of five years.
PIMCO Advisors also paid Mr. Poovey a $100,000 relocation loan which will be
forgiven over five years subject to certain conditions. At December 31, 1997,
the loan had an outstanding balance of $100,000.
 
  In July 1996, PIMCO Advisors made a $250,000 relocation loan to Robert M.
Fitzgerald, Senior Vice President and Chief Financial Officer of PIMCO
Advisors and PIMCO Holdings. The loan bears interest at 8% per annum, and
$200,000 of the principal and interest thereon will be forgiven over three
years subject to continued employment. At December 31, 1997, the loan had an
outstanding principal balance of $133,333.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
RELATIONSHIP BETWEEN PIMCO HOLDINGS AND PIMCO ADVISORS
 
 OPERATING AGREEMENT
 
  PIMCO Holdings and PIMCO Advisors are party to an Operating Agreement (the
"Operating Agreement") which, together with the PIMCO Advisors Partnership
Agreement, governs the ongoing relationship of PIMCO Holdings and PIMCO
Advisors. Pursuant to the Operating Agreement, PIMCO Holdings has agreed to
take actions from time to time so as to ensure that the number of outstanding
units is at all times equal to the number of PIMCO Advisors units held by
PIMCO Holdings and its subsidiaries which are allocable to the limited partner
interests in PIMCO Holdings. The Operating Agreement provides that upon any
issuance of PIMCO Holdings units, PIMCO Holdings shall contribute the
consideration, if any, received by PIMCO Holdings for such PIMCO Holdings
units to PIMCO Advisors in exchange for PIMCO Advisors units equal in number
to the number of such PIMCO Holdings units.
 
  The Operating Agreement provides that PIMCO Holdings shall at the request of
PIMCO Advisors adopt and maintain one or more unit incentive plans covering
PIMCO Holdings units or PIMCO Advisors units for the benefit of individuals
providing services to PIMCO Holdings, PIMCO Advisors and their respective
subsidiaries. In addition, the Operating Agreement provides that PIMCO
Holdings assumes and agrees to perform the obligations of PIMCO Advisors
under: (i) the PIMCO Advisors unit-based incentive plans (the 1993 Unit Option
 
                                      83
<PAGE>
 
Plan and 1996 Unit Incentive Plan (but with regard to options outstanding
immediately after giving effect to the Restructuring, only to the extent such
options are exercisable to purchase PIMCO Holdings units), the awards of which
were assumed under PIMCO Holdings' 1997 Unit Incentive Plan); (ii) the
Exchange Right issued by PIMCO Advisors in the Opgroup Transaction; and (iii)
the 1994 Registration Rights Agreement and the 1997 Registration Rights
Agreement (each as described under "--Registration Rights Agreements").
 
  The Operating Agreement provides that PIMCO Holdings may not, without the
consent of PIMCO Advisors, (a) carry on any business except in connection with
or incidental to (i) the performance of its duties as a general partner under
the PIMCO Advisors Partnership Agreement, (ii) the direct or indirect
acquisition, ownership or disposition of PIMCO Advisors units, and (iii) its
governance and existence; (b) merge or consolidate with or into any other
person, or sell or otherwise dispose of all or substantially all of its
assets, or effect a recapitalization with respect to PIMCO Holdings units, or
issue or agree to issue any equity securities other than PIMCO Holdings units;
or (c) create, incur, issue, assume, guarantee or otherwise become directly or
indirectly liable, contingently or otherwise, with respect to any
indebtedness. Finally, in the Operating Agreement PIMCO Holdings agrees to
exchange PIMCO Holdings units for PIMCO Advisors units as described below.
 
 EXCHANGE OPPORTUNITIES FOR PIMCO ADVISORS UNITHOLDERS
 
  PIMCO Holdings intends, twice each year at such times as may be permitted
under the PIMCO Advisors Partnership Agreement, to offer certain holders of
PIMCO Advisors units the opportunity to exchange those units for PIMCO
Holdings units on a one for one basis. PIMCO Holdings anticipates effecting
this exchange in a manner which will result in the issuance and resale (in the
case of affiliates of PIMCO Holdings) of the newly issued PIMCO Holdings units
being registered under the Securities Act of 1933, as amended. In addition,
under the Operating Agreement, PIMCO Holdings has agreed from time to time to
exchange PIMCO Holdings units for PIMCO Advisors units on a one for one basis
if the transfer would qualify as an "exempt transfer" under the PIMCO Advisors
Partnership Agreement.
 
 EXPENSE REIMBURSEMENT
 
  In accordance with the PIMCO Advisors Partnership Agreement, PIMCO Advisors
pays all of the expenses (other than taxes) of PIMCO Holdings. See "Executive
Compensation--Compensation of General Partner."
 
PGP INDEBTEDNESS
 
  The operations of PIMCO Advisors may be affected by the terms of the $130
million of indebtedness owed by PGP. Although this indebtedness does not
constitute an obligation of PIMCO Advisors or any of its subsidiaries, and the
documents governing the indebtedness are not binding on PIMCO Advisors or any
of its subsidiaries, the businesses of PIMCO Advisors have been and are
anticipated to continue to be conducted in compliance with the operating
restrictions in the documents governing the indebtedness in order to avoid a
default thereunder even though contrary courses of action may be in the best
interests of PIMCO Advisors. The operating restrictions, which remain in
effect until the debt matures in 2001 if the debt is not prepaid, include,
among other things, cash flow and interest coverage requirements and
restrictions on incurrence of indebtedness and liens, investments, asset
sales, mergers and consolidations, affiliate transactions, issuance of
additional PIMCO Advisors units and amendment of the PIMCO Advisors
Partnership Agreement. In particular, financial covenants relating to this
indebtedness could have the effect of inhibiting PIMCO Advisors' use of cash
for any purpose other than for distributions. The indebtedness is non-recourse
to PGP and is secured by, among other things, a pledge of certain PIMCO
Advisors units owned by PGP. In the event of a default under the indebtedness,
the lenders could foreclose upon the pledged PIMCO Advisors units which would
reduce the economic interests in PIMCO Advisors of PGP and its beneficial
owners. Management of PIMCO Advisors is currently in discussions with PGP and
its lenders concerning a modification to such indebtedness wherein PIMCO
Advisors would guarantee such indebtedness in exchange for a fee from PGP and
the release of certain of the restrictions relating to PIMCO Advisors in such
indebtedness. Also, PIMCO Advisors has obtained a commitment from a group of
lenders for a $500 million credit facility and has considered borrowing under
the
 
                                      84
<PAGE>
 
facility and lending to PGP an amount sufficient for PGP to repay its lenders,
thereby eliminating all restrictions relating to PIMCO Advisors under the PGP
indebtedness. There can be no assurances that any agreement with respect to
these matters will be reached, or as to the terms of any such possible
arrangements if an agreement were reached.
 
WITHDRAWAL AND REMOVAL OF A GENERAL PARTNER OF PIMCO HOLDINGS OR PIMCO
ADVISORS
 
  The PIMCO Holdings Partnership Agreement provides that, except under certain
limited exceptions, the general partner of PIMCO Holdings may withdraw as
general partner of PIMCO Holdings only if (i) such withdrawal is approved by
holders of a majority of PIMCO Holdings units and the general partner makes a
Partnership Assignment Determination, and (ii) counsel renders a Partnership
Limited Liability Determination and a Partnership Tax Determination. The
general partner may be removed by a vote of holders of PIMCO Holdings units
holding 80% or more of all outstanding PIMCO Holdings units if a successor
general partner is appointed, counsel makes a Partnership Limited Liability
Determination and a Partnership Tax Determination, the general partner makes a
Partnership Assignment Determination and such removal is approved by the
successor general partner. Also, interests in the general partner may be sold
or transferred without any prior approval or consent of the holders of PIMCO
Holdings units.
 
  The PIMCO Advisors Partnership Agreement provides that any general partner
may withdraw as a general partner of PIMCO Advisors only if (a) the general
partner transfers all of its PIMCO Advisors GP Units to an affiliate of such
general partner, and the affiliate is admitted as a general partner of PIMCO
Advisors in accordance with the PIMCO Advisors Partnership Agreement or (b)
such withdrawal is approved by holders of a majority of the units of limited
partner interest (other than those held by the general partners and their
affiliates) and if counsel renders an opinion that the limited partners do not
lose their limited liability pursuant to Delaware law or the PIMCO Advisors
Partnership Agreement (a "PIMCO Advisors Limited Liability Determination"),
and provides certain other opinions relating to the status of PIMCO Advisors
as a partnership for federal income tax purposes (a "PIMCO Advisors Tax
Determination") and the continuation of PIMCO Advisors advisory agreements (a
"PIMCO Advisors Assignment Determination"). The general partners may be
removed by a vote of unitholders holding 80% or more of all outstanding units
if PIMCO Advisors receives a PIMCO Advisors Limited Liability Determination, a
PIMCO Advisors Tax Determination and a PIMCO Advisors Assignment Determination
with respect to such removal and (ii) if such general partner is the sole
general partner, a person qualified to be general partner, which has agreed in
writing to carry on the business of PIMCO Advisors, is approved by the
partners of PIMCO Advisors as the successor general partner. However, by
virtue of PGP's and PIMCO Holdings' ownership of units, either of the general
partners can veto any such removal. Also, interests in a general partner may
be sold or transferred without any prior approval or consent of the holders of
PIMCO Advisors limited partnership units.
 
  In the event of withdrawal or removal of a general partner of PIMCO
Advisors, the departing general partner will become a limited partner and its
PIMCO Advisors GP Units will be converted into PIMCO Advisors limited
partnership units. At the time of such conversion, the departing general
partner must pay to PIMCO Advisors any negative balance in its capital
account. If PIMCO Advisors is indebted to the departing general partner at the
time of its withdrawal or removal, PIMCO Advisors will repay the general
partner, within 60 days, the amount of such indebtedness, subject to reduction
for damages incurred if the general partner withdraws in violation of the
PIMCO Advisors Partnership Agreement. All outstanding obligations incurred by
the departing general partner as general partner of PIMCO Advisors will be
assumed by the successor to the general partner, or if there is no successor,
by the remaining general partners.
 
INDEMNIFICATION
 
  The PIMCO Holdings Partnership Agreement requires PIMCO Holdings to
indemnify the general partner, its affiliates and all of its officers,
directors, partners, employees and agents (collectively, the "Indemnitees")
against any and all proceedings in which the Indemnitees may be involved, or
threatened to be involved, as a party or otherwise by reason of their
management of the affairs of PIMCO Holdings or which relates to or arises
 
                                      85
<PAGE>
 
out of PIMCO Holdings or related entities. The PIMCO Holdings Partnership
Agreement provides that such Indemnitees are not entitled to indemnification
with respect to any claim, issue or matter in which they have been adjudged
liable for actual fraud, willful misconduct or gross negligence, unless and
only to the extent that the court in which such action was brought, or another
court of competent jurisdiction, determines upon application that, despite the
adjudication of liability, but in view of all the circumstances of the case,
the Indemnitee is fairly and reasonably entitled to indemnification for such
liabilities and expenses as the court may deem proper.
 
  The PIMCO Holdings Partnership Agreement also provides that the general
partner will not be liable to PIMCO Holdings or the holders of PIMCO Holdings
units for errors in judgment or for breach of fiduciary duty (including breach
of any duty of care or any duty of loyalty) unless the general partner's
action or failure to act involved an act or omission that constitutes actual
fraud, gross negligence or willful or wanton misconduct.
 
  The PIMCO Advisors Partnership Agreement provides that PIMCO Advisors will
indemnify (i) any general partner, (ii) any former general partner, (iii) any
person which is or was an affiliate of any general partner or any former
general partner, (iv) any person which is or was an Associate (as defined in
the PIMCO Advisors Partnership Agreement) of any general partner, former
general partner, affiliate of a general partner or former general partner, or
PIMCO Advisors or its subsidiaries and (v) any person which is or was serving
at the request of PIMCO Advisors or any of its subsidiaries, any general
partner or any former general partner as an Associate of another person.
 
  The PIMCO Advisors Partnership Agreement also provides that neither a
general partner nor any indemnitee will be liable to PIMCO Advisors or the
unitholders for errors in judgment or for breach of fiduciary duty (including
breach of any duty of care or any duty of loyalty) unless it is proved by
clear and convincing evidence that the general partner's action or failure to
act involved an act or omission undertaken with deliberate intent to cause
injury to PIMCO Advisors or was undertaken with reckless disregard for the
best interests of PIMCO Advisors.
 
CONTRIBUTION AGREEMENT
 
  In connection with the acquisition of the investment advisory assets of
Opgroup, Opfin, Opgroup, PIMCO Advisors and Value Advisors LLC entered into a
contribution agreement (the "Contribution Agreement") pursuant to which
Opgroup, then a subsidiary of PIMCO Advisors, caused its subsidiary Opfin to
contribute (i) the ownership of Value Advisors LLC and the one percent general
partner interest in PIMCO Holdings to PIMCO Advisors, and then (ii) Opfin's
32.4% managing general partner interest in Oppenheimer Capital and the one
percent general partner interests in three subsidiaries of Oppenheimer Capital
to Value Advisors LLC (then a subsidiary of PIMCO Advisors). In exchange for
these contributions, Opfin received 6.0 million PIMCO Advisors Class C units
of limited partner interest. Each PIMCO Advisors Class C unit of limited
partner interest is entitled to the same proportionate share of profits,
losses and distributions as a PIMCO Advisors Class A unit of limited partner
interest, but with a minimum priority distribution of $2.75 per year and a
maximum distribution of $3.00 per year, or $0.75 per quarter subject to a
catch-up on an annual basis.
 
  Under the terms of the Contribution Agreement, if PIMCO Advisors or its
direct or indirect subsidiaries (other than Opgroup or Opfin) incurs a loss
relating to or arising from Opfin's investment advisory businesses or which is
otherwise attributable to the Opgroup merger agreement, and, as a result of
such loss, Opgroup receives an indemnification payment in excess of any loss
incurred by Opgroup or Opfin attributable to the same loss event (the excess
portion thereof, an "Excess Indemnification Payment"), then (i) if the
indemnification payment is in the form of a reduction of the face amount of
the Indemnity Certificate, Opfin shall return to PIMCO Advisors a number of
PIMCO Advisors units equal to the quotient of (x) 6,000,000 multiplied by the
principal amount of the reduction constituting such Excess Indemnification
Payment divided by (y) $265 million, or (ii) if the Excess Indemnification
Payment is in cash, Opgroup shall distribute the cash to PIMCO Advisors.
 
                                      86

  In addition, PIMCO Advisors agreed that if Opgroup or Opfin incurs a loss
for which Opgroup does not receive an indemnification payment in cash, PIMCO
Advisors will loan to Opgroup an amount equal to the loss. PIMCO Advisors
further agreed to loan Opgroup an amount sufficient to pay the remaining
principal and interest payments on the Opfin Debt. Accordingly, following the
closing of the Opgroup Transaction, PIMCO Advisors loaned $35 million to
Opgroup, which used a portion of the proceeds of this loan to retire the
indebtedness owed by Opfin to PIMCO Holdings.
 
REGISTRATION RIGHTS AGREEMENTS
 
  PIMCO Advisors is a party to (i) that certain Registration Rights Agreement
dated November 4, 1997 between PIMCO Advisors and former Opgroup stockholders
(the "1997 Registration Rights Agreement"), and (ii) that certain Registration
Rights Agreement dated as of November 15, 1994 between PIMCO Advisors and
certain of its unitholders (the "1994 Registration Rights Agreement").
Following the Restructuring, PIMCO Advisors was no longer obligated to effect
registrations under these agreements. However, pursuant to the Operating
Agreement, PIMCO Holdings has agreed to perform the obligations of PIMCO
Advisors under the 1997 Registration Rights Agreement and the 1994
Registration Rights Agreement, and PIMCO Holdings intends to provide
registration rights with respect to PIMCO Holdings units comparable to those
described below.
 
  The holders of registration rights under the 1997 Registration Rights
Agreement were granted (i) the right to initiate up to two registrations of
their registerable securities (subject to customary limitations, a minimum
sale requirement and priority rights of holders of registration rights under
the 1994 Registration Rights Agreement) and (ii) certain piggyback
registration rights in respect of registrations initiated by the partnership
or by other holders of registration rights granted pursuant to a separate
agreement, subject to approval of the managing underwriter. In the case of a
registration initiated by the partnership, participation in such registration
by the holders of registration rights under the 1997 Registration Rights
Agreement and other registration rights agreements could not be reduced to
less than 40%. The holders of registration rights under the 1994 Registration
Rights Agreement were granted (i) the right to initiate up to five demand
registrations on Form S-1 and an unlimited number of demand registrations on
Form S-3 (subject to customary limitations and a minimum sale requirement) and
(ii) piggy-back registration rights in respect of primary offerings by the
partnership similar to those held by the holders under the 1997 Registration
Rights Agreement. The holders under the 1994 Registration Rights Agreement
generally have priority over the holders under the 1997 Registration Rights
Agreement with respect to management of the registration process and inclusion
of shares in registrations initiated by holders of registration rights.

     This Amended and Restated Operating Agreement (this "Agreement") is entered
into as of 12:01 a.m. Pacific Standard Time on January 1, 1998 by and between
PIMCO Advisors Holdings L.P., a Delaware limited partnership formerly named

Advisors dated December 31, 1997 (the "Advisors Partnership Agreement").

     1. On November 30, 1997, the general partner of Advisors admitted Holdings
as an additional general partner of Advisors.

Holdings in exchange for (i) its interest in Oppenheimer Capital, a Delaware
general partnership, and (ii) cash in the amount of approximately $16,757,000.

     3. On December 31, 1997, the general partners of Advisors effected a
restructuring (the "Restructuring") pursuant to which all Class A LP Units held
by the public unitholders of Advisors were exchanged for units of limited
partner interest in Holdings (each, a "Holdings Unit").

Units on the New York Stock Exchange ceased, and Holdings became the sole
publicly traded  company through which Partnership Interests in Advisors are
held.

     5. The parties wish to confirm their mutual understanding with regard to
their relationship following the Restructuring.

     Section 5.1  Issuance of Certificates.

          (a)     Upon the issuance of Units to any Partner or other Person, the

     Section 5.2  Lost, Stolen, Destroyed or Mutilated Certificates.

          (a)     The Partnership shall issue a new Certificate in place of any
Certificate previously issued if the registered owner of the Units evidenced by

                  (i)   makes proof by affidavit, in form and substance

lost, stolen or destroyed;

precluded from making any claim against the Partnership or any Transfer Agent
for such Transfer or for a new Certificate.

          (c)     If a mutilated Certificate is surrendered to the Partnership,
the Partnership shall execute and deliver in exchange therefor a new Certificate

                               Transfer of Units

     Section 6.1  Transfer.

          Except as provided in Article XVI, no Units shall be Transferred
except in accordance with the terms and conditions set forth in this Article VI.
Any purported Transfer of Units not made in accordance with this Article VI or
Article XVI shall be null and void, and the purported Transferee shall not (i)
be admitted as a Partner, (ii) be deemed to be an assignee of the Units
purported to be Transferred within the meaning of Section 17-702 of the Delaware
Act, or (iii) have any rights to share in profits and losses, to receive any
distributions, or to receive any allocations of income, gain, loss, deduction,
or credit or similar item, with respect to the Units purported to be
Transferred.

     Section 6.2  Transfer of GP Units.

          GP Units may be Transferred by a General Partner (i) to an Affiliate
of such General Partner which has been admitted as a successor or additional
General Partner pursuant to Section 12.1(a), or (ii) to a General Partner in an
Exempt Transfer or a Semiannual Transfer.

     Section 6.3  Transfer of LP Units.

          LP Units may be Transferred by a Partner in an Exempt Transfer or a
Semiannual Transfer.

     Section 6.4  Regulation of Block Transfers.

          (a)     The General Partners may by Written Consent adopt such rules
consistent with Section 1.7704 of the Treasury Regulations with regard to Block
Transfers, including the calculation of the minimum number of Units qualifying
as a Block Transfer and the number of Units that should be counted against such
minimum number, as they shall determine in good faith are appropriate.

          (b)     If any Partner or group of related Partners (within the
meaning of Section 267(b) or Section 707(b)(1) of the Code) desires to effect a
Noncompliant Block Transfer, such Partner or group of Partners shall, as
promptly as practicable, give notice to the Partnership of such proposed
Noncompliant Block Transfer, including the names of the proposed Transferees and
the number of Units proposed to be Transferred to each such Transferee. If
several Partners or groups of related Partners give notices to the Partnership
that they desire to effect Noncompliant Block Transfers in the same calendar
year, and the number of such Noncompliant Block Transfers exceeds the number
which would qualify as Exempt Transfers in such calendar year, after taking into
account any prior Noncompliant Block Transfers during such calendar year, the
General Partners shall by Written Consent determine in good faith which of such

                                       21
<PAGE>
 
Partners or groups shall be permitted to effect Noncompliant Block Transfers in
such calendar year.

          (c)     The power and authority of the General Partners to determine
which Partners or groups of Partners may effect Noncompliant Block Transfers in
a calendar year may result in benefits to the Partners or groups permitted to
effect such Noncompliant Block Transfers (including certain General Partners or
their Affiliates) and disadvantages to the Partners or groups which are not
permitted to effect such Noncompliant Block Transfers (including other General
Partners or their Affiliates). No Partner shall have any cause of action
against, or right to receive any compensation from, the Partnership, the General
Partners or their Affiliates or any other Limited Partner or its Affiliates, as
a result of or in respect of any such determination or the disparate effects
thereof on any one or more Partners if the General Partners which consented to
the Written Consent made their determination in good faith.

     Section 6.5  Semiannual Transfers.

          (a)     There shall, if practicable, be two periods each year (each, a
"Semiannual Exchange Period"), each comprising twenty Business Days or such
greater number of Business Days as may be required under the Exchange Act,
during which the Public General Partners shall make registered exchange offers
to the Partners pursuant to which the Partners may exchange their Units for
publicly traded shares of a corporate Public General Partner, if any, or
publicly traded units of limited partner interest of a partnership Public
General Partner, if any, or both. The first Semiannual Exchange Period in a
year, if any, shall begin no earlier than March 15 and end no later than July 31
of such year, and the second Semiannual Exchange Period in a year, if any, shall
begin no earlier than August 15 and end no later than December 31 of such year.

          (b)     If one or more of the Public General Partners (each, a
"Participating Public General Partner") determines to make a registered exchange
offer in the period prescribed for a Semiannual Exchange Period, such Semiannual
Exchange Period shall begin on a date determined by the Participating Public
General Partners, which, if such Semiannual Exchange Period is in the first half
of the year, shall be as soon as practicable following the issuance of the last
to be issued of the Public General Partners' financial statements for the
immediately preceding year, or if such Semiannual Exchange Period is in the
second half of the year, shall be as soon as practicable following the issuance
of the last to be issued of the Public General Partners' financial statements
for the first six months of such year. If there is more than one Participating
Public General Partner, they shall cooperate in good faith to coordinate such
registered exchange offers.

          (c)     If there is no Public General Partner, or if the Public
General Partners determine not to make a registered exchange offer in the period
prescribed for a Semiannual Exchange Period, the General Partners shall
determine the date, if any, on which such Semiannual Exchange Period shall
begin.

                                       22
<PAGE>
 
          (d)     The General Partners shall endeavor in good faith to provide
two Semiannual Exchange Periods each year as provided in this Section 6.5;
provided, however, that no Partner shall have any cause of action against, or
right to receive any compensation from, any General Partner or its Affiliates as
a result of or in respect of a determination (i) by a Public General Partner to
not make a registered exchange offer in the period prescribed for a Semiannual
Exchange Period, or (ii) by the General Partners to provide less than two
Semiannual Exchange Periods in a year, if such Public General Partner or General
Partners made its or their determination in good faith.

          (e)     During a Semiannual Exchange Period, a Partner may Transfer
Units to a Public General Partner pursuant to its registered exchange offer, and
during the last five of the ten Business Days immediately following the end of
such Semiannual Exchange Period, a Partner may Transfer Units to any Qualified
Person. Any such Transfer shall comply with the provisions of Sections 6.3 and
6.5(f).

          (f)     If a Partner proposes to Transfer Units in a Semiannual
Transfer to a Qualified Person other than a Public General Partner pursuant to
its registered exchange offer, such Partner shall, at least five Business Days
prior to the end of the corresponding Semiannual Exchange Period, give notice to
the Partnership of such proposed Transfer, including the name of the proposed
Transferee and the number of Units proposed to be Transferred. If the total
number of Units either tendered pursuant to a registered exchange offer or
proposed to be Transferred in Semiannual Transfers during a Semiannual Transfer
Period, plus the total number of Units Transferred in Semiannual Transfers
during the preceding Semiannual Transfer Period, if any, in the same year,
exceeds 10% of the total number of outstanding Units (the "10% Limit"), the
number of Units tendered pursuant to registered exchange offers and proposed to
be Transferred in Semiannual Transfers during such Semiannual Transfer Period
shall be reduced pro rata such that the 10% Limit is not exceeded. The
Partnership shall immediately give notice of such reduction to each Public
General Partner and each Partner which gave notice to the Partnership of a
proposed Transfer. Exempt Transfers shall not be counted against the 10% Limit.

          (g)     The General Partners may by Written Consent adopt such rules
consistent with Section 1.7704 of the Treasury Regulations with regard to the
calculation of the 10% Limit as they shall determine in good faith are
appropriate.

     Section 6.6  Additional Restrictions on Transfers.

          A Partner shall not Transfer any of its Units if such Transfer would
(i) violate then applicable federal and state securities laws or rules and
regulations of the Commission, any state securities commission or any other
governmental authorities with jurisdiction over such Transfer, (ii) result in an
Adverse Partnership Event or an Assignment Event, or (iii) affect the
Partnership's existence or qualification as a limited partnership under the
Delaware Act.

with the provisions of this Agreement regarding Transfers and proposed Transfers
of Units.

          In addition to any other remedies which may be available at law or in
equity for a breach or attempted breach by a Partner of the provisions of this
Article VI, (i) the Partnership shall be entitled to injunctive relief and to
specific performance of such provisions, and (ii) the General Partners may
impose penalties on such Partner(including forfeiture of all or part of its
Units) for such breach or attempted breach. Any Units forfeited pursuant to this
Section 6.8 shall be canceled and retired.


                                  ARTICLE VII
                               Capital Accounts

     Section 7.1  Capital Accounts.

          (a)     The Partnership shall maintain for each Unitholder a separate
Capital Account in accordance with Section 704 of the Code. Such Capital Account
shall be increased by (i) the cash amount or Net Value of all actual and deemed
Contributions made by such Unitholder to the Partnership and (ii) Net Income
allocated to such Unitholder pursuant to Article VIII and decreased by (i) the
cash amount or Net Value of all actual and deemed distributions of Partnership
Assets made to such Partner and (ii) Net Loss allocated to such Unitholder
pursuant to Article VIII.

          (b)     Upon the issuance of any Units to or for the benefit of any
Associate of the Partnership or any of its Subsidiaries, or any successor to
such Associate, as compensation for services rendered or to be rendered to a
General Partner, the Partnership or any of its Subsidiaries by such Associate,
the Person receiving such Units shall be deemed to have made a Contribution to
the Partnership in an amount equal to the product of (i) the number of Units so
issued, and (ii) the Unit Price on the date of such issuance.

     Section 7.2  Adjustments Affecting Net Income or Net Loss.

          (a)     In accordance with the requirements of Section 704(c) of the
Code and Treasury Regulations Section 1.704-1(b)(2)(iv)(d), any deductions for
depreciation, cost recovery or amortization attributable to Contributed Property
shall be determined as if the adjusted basis of such Contributed Property on the
date it was acquired by the Partnership was equal to the Carrying Value of such
Contributed Property. Upon an adjustment pursuant to Section 7.4 to the Carrying
Value of any Partnership Asset subject to depreciation, cost recovery or
amortization, any further deductions for such depreciation, cost recovery

                                       24
<PAGE>
 
or amortization attributable to such Partnership Asset shall be determined as if
the adjusted basis of such Partnership Asset was equal to the Carrying Value of
such Partnership Asset immediately following such adjustment.

          (b)     Any income, gain or loss attributable to the disposition of
any Partnership Asset shall be determined by the Partnership as if the adjusted
basis of such Partnership Asset as of such date of disposition was equal in
amount to the Partnership's Carrying Value with respect to such Partnership
Asset as of such date.

          (c)     The computation of all items of income, gain, loss and
deduction shall be made, as to those items described in Section 705(a)(1)(B) or
705(a)(2)(B) of the Code, without regard to the fact that such items are not
includable in gross income or are neither currently deductible nor capitalizable
for federal income tax purposes. For this purpose, amounts paid or incurred to
organize the Partnership or to promote the sale of Partnership Interests that
are neither deductible nor amortizable under Section 709 of the Code, and
deductions for any losses incurred in connection with the sale or exchange of
Partnership Assets disallowed pursuant to Section 267(a)(1) or 707(b) of the
Code, shall be treated as expenditures described in Section 705(a)(2)(B) of the
Code.

     Section 7.3  Adjustments for Transfers.

          If a General Partner Transfers LP Units, and if immediately prior to
such Transfer such General Partner has a negative Capital Account balance, the
Transferee shall be credited with a zero balance in its Capital Account relating
to such LP Units, and such General Partner shall retain its negative Capital
Account balance.

     Section 7.4  Adjustments for Contributions or Redemptions.

          In accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(f),
in connection with either (i) a Contribution (other than a de minimis amount) by
a new or existing Partner in consideration for a Partnership Interest or (ii) a
distribution of Partnership Assets (other than a de minimis amount) in
consideration for a Partnership Interest, the Capital Accounts of all Partners
and the Carrying Values of all Partnership Assets shall be adjusted upwards or
downwards to reflect any Unrealized Gain or Unrealized Loss attributable to each
Partnership Asset, as if such Unrealized Gain or Unrealized Loss had been
recognized upon an actual sale of such Partnership Asset at such time and had
been allocated to the Partners pursuant to Article VIII. For purposes of
determining such Unrealized Gain or Unrealized Loss, the fair market value of
Partnership Assets shall be determined by the General Partners.

     Section 7.5  Adjustments for Distributions in Kind.

          In accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(e),
immediately prior to the actual or deemed distribution of any Partnership Asset
in kind, the Capital Accounts of all Partners and the Carrying Values of such
Partnership Asset shall be adjusted upward or downward to reflect any Unrealized
Gain or Unrealized Loss attributable to such Partnership Asset as if such
Unrealized Gain or Unrealized Loss had been recognized upon an actual sale of
such Partnership Asset immediately prior to such distribution and had been
allocated to the Partners at such time pursuant to Article VIII. For purposes of
determining such Unrealized Gain or Unrealized Loss, the fair market value of
Partnership Assets shall be determined by the General Partners.


                                 ARTICLE VIII
                         Distributions and Allocations

     Section 8.1  Cash Distributions.

          With respect to each fiscal quarter, commencing with the fiscal
quarter ending March 31, 1998, the Partnership shall distribute an amount in
cash equal to the Distributable Cash for such quarter. Such distributions shall
be made to Unitholders of record as of the close of business on the last day of
each such fiscal quarter, and shall be paid not more than 30 days after the last
day of each such fiscal quarter. Such distributions shall be made in accordance
with the following priorities:

                  (i)   First, to such Unitholders holding Class C Units, pro
rata in accordance with their Class C Units, until the cash distributions made
pursuant to this clause (i) with respect to each Class C Unit equal the Class C
Quarterly Priority Amount;

                  (ii)  Second, to such Unitholders holding Class A Units and
Class B Units, pro rata in accordance with their Class A Units and Class B
Units, without regard to whether such Units are Class A Units or Class B Units,
until the cash distributions made pursuant to this clause (ii) with respect to
each Class A Unit and Class B Unit equal the Class A Quarterly Priority Amount;

                  (iii) Third, to such Unitholders holding Class A Units, Class
B Units or Class C Units, pro rata in accordance with their Class A Units, Class
B Units and Class C Units, without regard to whether such Units are Class A
Units, Class B Units or Class C Units, until the cash distributions made
pursuant to the preceding clauses (i) and (ii) and this clause (iii) with
respect to each Class A Unit, Class B Unit and Class C Unit equal the Class C
Quarterly Cap;

<PAGE>
 
                  (iv)  Fourth, to such Unitholders holding Class A Units or
Class B Units, pro rata in accordance with their Class A Units and Class B
Units, without regard to whether such Units are Class A Units or Class B Units;

provided, however, that the Partnership may withhold distributions to the
holders of Class A Units and Class B Units to protect the distributions in
respect of the Class C Units in future fiscal quarters.

     Section 8.2  General Rules with Respect to Distributions.

          (a)     The General Partners are authorized to distribute Partnership
Assets in kind. Any Partnership Asset distributed in kind shall be valued at its
fair market value on the date of distribution and shall be distributed in
accordance with Section 8.1. Capital Accounts and Carrying Values shall be
adjusted in accordance with Section 7.2(e).

          (b)     The General Partners shall specify a Record Date for any
distribution other than a quarterly distribution, and any Partnership Assets
distributed shall be distributed to the Unitholders of the relevant class or
series as of the Record Date.

          (c)     Any amount of taxes withheld pursuant to Section 9.7, and any
amount of taxes, interest or penalties paid by the Partnership to any
governmental entity, with respect to amounts allocated or distributable to a
Unitholder shall be deemed to be a distribution or payment to such Unitholder
and shall reduce the amount otherwise distributable to such Unitholder pursuant
to this Article VIII.

          (d)     Distributions made to Unitholders shall be made to
"Unitholders" as defined in Article I without regard to the last sentence of the
definition of "Unitholder".

          (e)     The Partnership shall not make a distribution to any Partner
on account of its Partnership Interest if such distribution would violate
Section 17-607 of the Delaware Act or other applicable law.

     Section 8.3  Allocations of Net Income and Net Loss.

          (a)     Net Income and Net Loss shall be determined for each fiscal
year and allocated annually. Except as otherwise provided in Section 8.4, Net
Income and Net Loss for a fiscal year shall be allocated as set forth in this
Section 8.3.

          (b)     If the Partnership has Net Income for a fiscal year, one-
twelfth of such Net Income shall be treated as earned in each fiscal month of
such fiscal year. Net Income so treated as earned in a fiscal quarter of such
fiscal year shall first be allocated to the Class C Units in the amount of the
distributions made to the Class C Unitholders with respect to such fiscal
quarter; any remaining Net Income shall be allocated to the Class A Units and
Class B Units in

                                       27
<PAGE>
 
proportion to the respective distributions made to the Class A Unitholders and
Class B Unitholders with respect to such fiscal quarter. Net Income for a fiscal
quarter which is allocated to the Class C Units shall be further allocated to
the Class C Unitholders as of the close of business on the last day of each of
the three fiscal months in such fiscal quarter, in proportion to the number of
Class C Units held by such Unitholders as of the close of business on each such
day. One-third of the Net Income for a fiscal quarter which is allocated to the
Class A Units or Class B Units shall be further allocated to the Unitholders of
such class of Units as of the close of business on the last day of each fiscal
month in such fiscal quarter, in proportion to the number of Units of such class
held by each such Unitholder as of the close of business on such day.

          (c)     If the Partnership has a Net Loss for a fiscal year, one-
twelfth of such Net Loss shall be treated as incurred in each fiscal month of
such fiscal year. Net Loss so treated as incurred in a fiscal month shall first
be allocated to the Unitholders having positive Capital Account balances so as
to cause their respective Capital Account balances to be in (or, if not
possible, closer to) the same proportion to each other as their respective
Percentage Interests and then in accordance with their respective Percentage
Interests until all such positive balances have been eliminated; any remaining
Net Loss shall be allocated to the General Partners in respect of their GP
Units. To the extent subsequent Net Income of the Partnership does not exceed
Net Loss previously allocated pursuant to this Section 8.3(c), such Net Income
shall first be allocated to the General Partners in respect of their GP Units
until such allocated Net Income equals Net Loss previously allocated to the
General Partners pursuant to this Section 8.3(c); any remaining Net Income shall
be allocated to the Unitholders in the same proportions and amounts as Net Loss
was previously allocated pursuant to this Section 8.3(c). For purposes of this
Section 8.3(c), the determination of Capital Account balances shall be made
after giving effect to all distributions of cash made with respect to fiscal
quarters before the fiscal month in question pursuant to Section 8.1.

          (d)     If the Partnership has an item of extraordinary income during
a fiscal month which results in an extraordinary distribution to the Class A
Unitholders and Class B Unitholders with respect to the fiscal quarter which
includes such fiscal month, such item of extraordinary income shall be allocated
to the Class A Units and Class B Units in proportion to the respective
extraordinary distributions made to the Class A Unitholders and Class B
Unitholders with respect to the fiscal quarter which includes such fiscal month,
and shall be further allocated to the Class A Unitholders and Class B
Unitholders as of the close of business on the last day of such fiscal month, in
proportion to the number of Units of each such class held by each such
Unitholder as of the close of business on such day. The General Partners shall
determine whether an item of Partnership income is extraordinary and results in
an extraordinary distribution, and the amount of such extraordinary
distribution.

          (e)     Except as otherwise provided in Section 8.5, items of income,
gain, loss and deduction shall be allocated among the Unitholders in the same
proportion as items

                                       28
<PAGE>
 
comprising Net Income or Net Loss, as the case may be, are allocated among the
Unitholders, and credits shall be allocated as provided in Treasury Regulations
Section 1.704-1(b)(4)(ii).

     Section 8.4  Special Provisions Governing Capital Account Allocations.

          (a)     In the event that any Partner has a deficit Capital Account at
the end of any Partnership fiscal year which is in excess of such Partner's
obligation (including any deemed obligation under Treasury Regulations or
temporary Treasury Regulations), if any, to restore an amount to the
Partnership, and such excess deficit exists following the allocations referred
to in Sections 8.3(b) and (c), such Partner shall be allocated Net Income in
proportion to such remaining excess deficit amounts.

          (b)     If any Partner unexpectedly receives any adjustments,
allocations or distributions described in Treasury Regulations Section 1.704-
1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), Net
Income or items of income and gain shall be specially allocated to such Partner
in an amount and manner sufficient to eliminate, to the extent required by the
Treasury Regulations, a deficit in its Capital Account (computed as provided in
Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(3)) as quickly as possible.
This Section 8.4(b) is intended to constitute a "qualified income offset" within
the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(3) and shall be
interpreted to comply with the requirements of such regulation. Any special
allocations of items of income or gain pursuant to this Section 8.4(b) shall be
taken into account in computing subsequent allocations of Net Income or Net Loss
so that the net amounts of any items subsequently so allocated shall, to the
extent possible, be equal to the net amounts that would have been allocated to
each Partner if such special allocations had not occurred.

          (c)     In the event there is a net decrease in Minimum Gain during a
Partnership taxable year, the Partners shall be allocated items of income and
gain in accordance with Treasury Regulations Section 1.704-2(f). Any Partner's
share of Minimum Gain shall be determined in accordance with Treasury
Regulations Section 1.704-2(g). This Section 8.4(c) is intended to comply with
the minimum gain chargeback requirement of Treasury Regulations Section 1.704-2
and shall be interpreted to comply with the requirements of such regulation. Any
special allocations of items of income or gain pursuant to this Section 8.4(c)
shall be taken into account in computing subsequent allocations of Net Income or
Net Loss so that the net amounts of any items subsequently so allocated and the
special allocations shall, to the extent possible, be equal to the net amounts
that would have been allocated to each Partner if such special allocations had
not occurred.

          (d)     To the extent required by Treasury Regulations Section 1.704-
2(i), any tax items of the Partnership that are attributable to a non-recourse
debt of the Partnership that constitutes "partner non-recourse debt" as defined
in Treasury Regulations Section 1.704-2(b)(4) shall be allocated in accordance
with the provisions of Treasury Regulations Section 1.704-2(i). This Section
8.4(d) is intended to satisfy the requirements of Treasury Regulations Section

                                       29
<PAGE>
 
1.704-2(i) (including the partner nonrecourse minimum gain chargeback
requirements) and shall be interpreted to comply with the requirements of such
regulation. Any special allocations pursuant to this Section 8.4(d) shall be
taken into account in computing subsequent allocations of Net Income or Net Loss
so that the net amounts of any items subsequently so allocated and the special
allocations shall, to the extent possible, be equal to the net amounts that
would have been allocated to each Partner if such special allocations had not
occurred.

          (e)     The General Partners shall make special allocations of Net
Income or Net Loss or items of income, gain, loss or deduction to GP Units as
may be necessary to permit conversion of such Units to LP Units in accordance
with Section 4.1. For purposes of allocating income, gain, loss or deduction to
LP Units that were converted from GP Units for periods following such
conversion, the Units shall be deemed as of the effective date of such
conversion to have been allocated the same amount of income, gain, loss and
deductions and to have received the same distributions as the LP Units
outstanding prior to such conversion.

          (f)     If and to the extent that any Partner is deemed to recognize
income as a result of any transaction between such Partner and the Partnership
pursuant to Section 482, Section 483, Sections 1272-1274 or Section 7872 of the
Code, or any similar provision now or hereafter in effect, any corresponding
loss or deduction of the Partnership shall be allocated to the Partner who was
charged with such income. In addition, if all or part of the deductions claimed
by the Partnership for compensation to its employees is disallowed, the income
attributable to such disallowed deductions will be specially allocated to the
General Partners, and any subsequent deductions related to such compensation
will be specially allocated to the General Partners.

          (g)     In addition to the other special allocations that the General
Partners may make under this Section 8.4, to preserve uniformity of Units
(subject to the priority distribution rights of certain classes of Units) the
General Partners may make special allocations of Net Income or Net Loss or items
of income, gain, loss or deduction, but only if such allocations would not have
a material adverse effect on the Unitholders (other than the General Partners)
and if they are consistent with the principles of Section 704 of the Code.

     Section 8.5  Special Provisions Governing Tax Allocations.

          (a)     In the case of Contributed Property, items of income, gain,
loss, depreciation, amortization and cost recovery deductions attributable to
such property shall be allocated among the Partners in a manner consistent with
the principles of Section 704(c) of the Code that takes into account the
variation between the Net Value of such property and its adjusted basis, at the
time of contribution, to the extent such allocation reduces Book-Tax
Disparities.

          (b)     Items of income, gain, loss, depreciation and cost recovery
deductions attributable to Adjusted Property shall (i) first, be allocated among
the Partners in a manner

                                       30
<PAGE>
 
consistent with the principles of Section 704(c) of the Code to take into
account the Unrealized Gain or Unrealized Loss attributable to such property and
the allocation thereof pursuant to Section 8.3(b) or 8.3(c) to the extent such
allocation reduces Book-Tax Disparities, and (ii) second, in the event such
property was originally Contributed Property, be allocated among the Partners in
a manner consistent with Section 8.5(a).

          (c)     To the extent permissible under applicable Treasury
Regulations, the amount of any gain from a disposition of property allocated to
a Partner pursuant to Section 8.5(a) or 8.5(b) shall be deemed to be Recapture
Income to the extent such Partner has been allocated or has claimed any
deduction directly or indirectly giving rise to the treatment of such gain as
Recapture Income.

          (d)     All items of income, gain, loss, deduction and credit
recognized by the Partnership and allocated to the Partners in accordance with
this Article VIII shall be determined without regard to any adjustment made
pursuant to Section 743 of the Code; provided, however, that such allocations,
once made, shall, if an election under Section 754 of the Code is in effect, be
adjusted as necessary or appropriate to take into account those adjustments
permitted by Section 743 of the Code, and any adjustments made pursuant to
Section 734 of the Code shall be allocated to the extent permitted under and in
accordance with the rule of Treasury Regulations Section 1.704-1(b)(2)(iv)(m).

     Section 8.6  Allocations Upon Dissolution.

          If upon dissolution of the Partnership pursuant to Article XVII, and
after taking into account all allocations of Net Income and Net Loss (and other
tax items) under this Article VIII, distributions, if they were to be made to
Unitholders in accordance with their respective Capital Accounts, would result
in unequal distributions on their Units, then (i) gross items of income and gain
(and other tax items) for the taxable year of final distribution, and, to the
extent permitted under Section 761(c) of the Code, gross items of income and
gain (and other tax items) for the immediately preceding taxable year, shall be
allocated first to the Class C Unitholders until the Capital Account balance
allocable to each Class C Unit is equal, and (ii) the same procedure shall be
followed with respect to Class A Units and Class B Units until the Capital
Account balance allocable to each Class A Unit and Class B Unit is equal.

     Section 8.7  Changes in Allocation Methods.

          The General Partners may revise, alter or otherwise modify the
allocation methods set forth in this Article VIII (i) to the extent that they
determine that the application of such methods would result in a substantial
mismatching of the allocation of Net Income or Net Loss attributable to a period
and the distribution of cash attributable to the same period as between the
Transferor and Transferee of a Unit that could be minimized by the application
of an alternative tax allocation method, or (ii) to the extent necessary to
conform the Partnership's tax allocations to the requirements of the Code or any
Treasury Regulations.

may maintain its books and records in other than written form, if such form is
capable of conversion into written form within a reasonable time. The
classification, realization and recognition of income, gains, losses,
deductions, credits and other items for financial reporting purposes shall be on
the accrual basis in accordance with generally accepted accounting principles.

          The fiscal year of the Partnership shall be the same as its taxable
year for federal income tax purposes.

     Section 9.3  Taxable Year.

          The Partnership shall prepare and timely file such returns relating to
Partnership income, gains, losses, deductions and credits, as may be required
for federal, state and local income tax purposes, and within 90 days after the
close of the taxable year, the Partnership shall mail to the Limited Partners
the tax information reasonably required for their federal, state and local
income tax reporting purposes. The classification, realization and recognition
of income, gains, losses, deductions, credits and other items for federal income
tax purposes shall be on the accrual basis.

     Section 9.5  Tax Elections.

          (a)     The General Partners may make the election under Section 754
of the Code in accordance with applicable regulations thereunder. In the event
the General Partners make such election, the General Partners reserve the right
to seek to revoke such election upon their determination that such revocation is
in the best interests of the Unitholders.

          (b)     The General Partners shall determine whether to make any other
elections available under the Code or under any state's tax laws on behalf of
the Partnership.

     Section 9.6  Other Tax Matters.

          (a)     The General Partners shall make special allocations to the
Partners of Net Income or Net Loss or items of income, gain, loss, deduction or
credit that are consistent with the principles of Section 704(c) of the Code and
shall amend the provisions of this Agreement as appropriate to reflect the
proposal or promulgation of Treasury Regulations under Subchapter K of the Code
or otherwise to cause allocations under Article VIII to be respected for federal
income tax purposes.

          (b)     The General Partners may adopt and employ such methods and
procedures for (i) the maintenance of book and tax capital accounts, (ii) the
determination and allocation of adjustments under Sections 704(c), 734 and 743
of the Code, (iii) the determination and allocation of Net Income, Net Loss,
taxable income, taxable loss and items thereof under this Agreement and pursuant
to the Code, (iv) the determination of the identities and tax classification of

basis, (viii) conventions for the determination of cost recovery, depreciation
and amortization deductions and the maintenance of inventories, (ix) the
recognition of the Transfer of Units, and (x) compliance with other tax-related
requirements, including without limitation the use of filing and reporting
procedures similar to those employed by other publicly-traded partnerships, as
they determine are necessary and appropriate to execute the provisions of this
Agreement, to comply with federal and state tax laws, and to achieve uniformity
and fungibility of Units (subject to the priority distribution rights of Class C
Units).

          (c)     If the General Partners determine that no reasonable allowable
convention or other method is available to preserve the uniformity of Units
(subject to the priority distribution rights of certain classes of Units) or the
General Partners so elect, Units may be separately identified as distinct
classes to reflect differences in tax consequences.

     Section 9.7  Withholding.

          The General Partners are authorized to take any action that they
determine to be necessary and appropriate to cause the Partnership to comply

respects as an association taxable as a corporation for federal income tax
purposes, and (ii) shall be deemed satisfied by an Opinion of Counsel containing
such conditions, limitations and qualifications as are acceptable to the General
Partners.

respect to such removal, and (ii) if such General Partner is the sole General
Partner, a Person qualified to be General Partner, which has agreed in writing
to carry on the business of the Partnership, is Approved by the Unitholders as
successor General Partner. Such Person shall be admitted to the Partnership as a

the Departing General Partner.

     Section 13.2 Interest of Departing General Partner.

          (a)     A Departing General Partner shall become a Limited Partner,

Partner at the effective date of its withdrawal or removal for funds advanced,

Departing General Partner the full amount of such indebtedness;

                                       42

provided, however, that if the Departing General Partner has withdrawn as a
General Partner in violation of this Agreement, the Partnership may offset
against the amount of such indebtedness any damages resulting from such breach.

successor, the remaining General Partners, shall (i) assume all outstanding
obligations incurred by the Departing General Partner as a General Partner of
the Partnership, and (ii) take all such action as shall be necessary to
terminate any guarantees of the Departing General Partner and any of its
Affiliates of any obligations of the Partnership. If for whatever reason the
creditors of the Partnership will not consent to such termination of guarantees,
the successor to the Departing General Partner, or if there is no successor, the
remaining General Partners, shall indemnify the Departing General Partner for
any costs and expenses incurred by the Departing General Partner on account of
such guarantees pursuant to an agreement reasonably satisfactory in form and
substance to the Departing General Partner.

     Section 13.3 Business May Be Carried On After Event of Withdrawal.

                       Partnership Meetings; Amendments

     Section 14.1 Partnership Meetings.

          Meetings of Unitholders may be called by the General Partners or the
Liquidator or by Unitholders holding at least 10% of the outstanding Units. Any
Unitholder calling a meeting shall specify the number of Units as to which the
Unitholder is exercising the right to call a meeting, and only those Units shall
be counted for the purpose of determining whether the 10% standard of the
preceding sentence has been met. Unitholders shall call a meeting by delivering
a notice to the Partnership stating that the signing Unitholders wish to call a
meeting and indicating the specific purposes for which the meeting is to be
called. Action at the meeting shall be limited to those matters specified in
such notice, and no Unitholder may propose, at such

                                       43
<PAGE>
 
meeting, any other matter to be considered by the Unitholders. Within 60 days
after receipt of such a notice from Unitholders or within such greater time as
may be reasonably necessary for the Partnership to comply with any statutes,
rules, regulations, listing agreements or similar requirements governing the
holding of a meeting or the solicitation of proxies for use at such a meeting,
the Partnership shall send a notice of the meeting to the Unitholders, stating
the specific purposes for which the meeting is called. A meeting shall be held
at a reasonable time and convenient place determined by the General Partners or
the Liquidator, as the case may be, on a date not more than 60 days after the
mailing of notice of the meeting. No action shall be taken at a meeting which is
opposed by the General Partners or the Liquidator unless the Partnership has
received a Limited Liability Opinion, a Tax Opinion and an Assignment Opinion
with respect to such action.

     Section 14.2 Record Date.

          The General Partners or the Liquidator, if any, shall set a Record
Date for the determination of the Unitholders entitled to notice of and to vote
at a meeting or adjourned meeting of Unitholders, which shall not be less than
10 days nor more than 60 days before the date of the meeting (unless such
requirement conflicts with any law, rule, regulation, guideline or requirement,
in which case such law, rule, regulation, guideline or requirement shall
govern).

     Section 14.3 Notice of Meeting.

          Notice of a meeting called pursuant to Section 14.1 shall be given in
writing either personally or by mail or other means of written communication
addressed to each Unitholder of record as of the close of business on the Record
Date for the meeting at the address of such Unitholder appearing on the books of
the Transfer Agent. An affidavit or certificate of mailing of any notice in
accordance with the provisions of this Section 14.3 executed by an officer of
the Partnership, the Transfer Agent or a mailing organization shall be prima
facie evidence of the giving of notice. If any notice addressed to a Unitholder
at its address is returned to the Partnership by the United States Postal
Service marked to indicate that the United States Postal Service is unable to
deliver it, such notice and any subsequent notices shall be deemed to have been
duly given without further mailing if they are available for the Unitholder at
the principal executive office of the Partnership for a period of one year from
the date of the giving of the notice to all other Unitholders.

     Section 14.4 Adjournment.

          When a meeting is adjourned to another time or place, notice need not
be given of the adjourned meeting and a new Record Date need not be fixed if the
time and place thereof are announced at the meeting at which the adjournment is
taken, unless such adjournment shall be for more than 60 days. At the adjourned
meeting, the Partnership may transact any business that might have been
transacted at the original meeting. If the adjournment is for more than 60 days

                                       44
<PAGE>
 
or if a new Record Date is fixed for the adjourned meeting, a notice of the
adjourned meeting shall be given in accordance with Section 14.3.

     Section 14.5 Waiver of Notice; Consent to Meeting; Approval of Minutes.

          The transactions of any meeting of Unitholders, however called and
noticed, and wherever held, are as valid as though effected at a meeting duly
held after regular call and notice if a quorum is present either in person or by
proxy and if, either before or after the meeting, each of the Unitholders
entitled to vote who is not present in person or by proxy, signs a written
waiver of notice or a consent to the holding of the meeting or an approval of
the minutes thereof. All waivers, consents and approvals shall be filed with the
Partnership records or made a part of the minutes of the meeting. Attendance of
a Unitholder at a meeting shall constitute a waiver of notice of the meeting,
except when the Unitholder objects, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened; provided, that attendance at a meeting shall not be deemed to
constitute a waiver of any right to object to the consideration of matters
required to be included in the notice of the meeting, but not so included, if
the objection is expressly made at the meeting.

     Section 14.6 Quorum and Required Vote.

          (a)     The presence in person or by proxy of a majority of the Units
entitled to vote shall constitute a quorum at a meeting of Unitholders;
provided, that if a separate vote by certain Unitholders or by a class or series
of Units is required by this Agreement, the presence in person or by proxy of a
majority of Units held by such Unitholders or a majority of the outstanding
Units of such class or series, present in person or by proxy and entitled to
vote, shall constitute a quorum with respect to that vote.

          (b)     At any meeting of the Unitholders duly called and held in
accordance with this Agreement at which a quorum is present, the affirmative
vote of the majority of Units present in person or by proxy and entitled to
vote, or such different or higher percentage as may be required by this
Agreement, shall be the act of the Unitholders; provided, that if a separate
vote of certain Unitholders or by a class or series of Units is required by this
Agreement, the affirmative vote of the majority of Units held by such
Unitholders or a majority of the outstanding Units or such class or series,
present in person or by proxy and entitled to vote, or such different or higher
percentage as may be required by this Agreement, shall be the act of such
Unitholders or such class or series

          (c)     The Unitholders present at a duly called or held meeting at
which a quorum is present may continue to transact business until adjournment,
notwithstanding the withdrawal of enough Unitholders to leave less than a
quorum, if any action taken (other than adjournment) is approved by Unitholders
holding the requisite percentage of Units specified in this Agreement. In the
absence of a quorum, any meeting of Unitholders may be adjourned from time to
time by the General Partners or upon the affirmative vote of Unitholders holding
a

                                       45
<PAGE>
 
majority of the Units represented either in person or by proxy and entitled to
vote, but no other business may be transacted.

     Section 14.7 Conduct of Meeting.

          The General Partners or the Liquidator, if any, shall have the
exclusive right and full power and authority to conduct any meeting of
Unitholders, and shall determine the Persons entitled to vote, the existence of
a quorum, the satisfaction of the requirements of this Article XIV, the conduct
of voting, the validity and effect of any proxies, and the determination of any
controversies, votes or challenges arising in connection with or during the
meeting or voting. The General Partners or the Liquidator, as the case may be,
shall designate a person to serve as chairman of the meeting, and shall further
designate a person to serve as secretary and to take the minutes of the meeting,
in either case including, without limitation, a Partner, an employee or agent of
a General Partner, or an officer of the Partnership. All minutes shall be kept
with the records of the Partnership maintained by the General Partners. The
General Partners or the Liquidator, as the case may be, may make such other
regulations consistent with applicable law and this Agreement as they may deem
advisable concerning the conduct of any meeting of the Unitholders, including
regulations in regard to the appointment of proxies, the appointment and duties
of inspectors of election, and the submission and examination of proxies and
other evidence of the right to vote.

     Section 14.8 Action Without a Meeting.

          (a)     Any action that may be taken at a meeting of the Unitholders
may be taken without a meeting if written approvals setting forth the action so
taken are given by Unitholders holding not less than the minimum number of Units
that would be necessary to take such action at a meeting at which all the
Unitholders were present and voted. Prompt notice of the taking of an action
without a meeting shall be given to the Unitholders who have not approved such
action.

          (b)     If the General Partners or the Liquidator, if any, submit an
action or actions to the Partners for written approval, the General Partners or
the Liquidator, as the case may be, shall set a Record Date for the
determination of the Unitholders entitled to give or withhold written approval
of such action or actions, which shall not precede the date on which the Record
Date is determined and shall not be more than ten days after such date (unless
such requirement conflicts with any law, rule, regulation, guideline or
requirement, in which case such law, rule, regulation, guideline or requirement
shall govern).

          (c)     If any Person other than the General Partners or the
Liquidator, if any, submits an action or actions to the Partners for written
approval, the Record Date for the determination of the Unitholders entitled to
give or withhold written approval of such action or actions shall be the date on
which the first duly executed written approval setting forth the action or
actions taken or proposed to be taken is delivered to the Partnership at its
principal office by hand or by registered or certified mail, return receipt
requested (unless such requirement conflicts

                                       46
<PAGE>
 
with any law, rule, regulation, guideline or requirement, in which case such
law, rule, regulation, guideline or requirement shall govern).

          (d)      No written approval shall be effective unless (i) such
written approval sets forth the action or actions taken or proposed to be taken,
and is delivered to the Partnership within 90 days after the Record Date for the
determination of the Unitholders entitled to give or withhold written approval
of such action or actions and (ii) if such action or actions were not submitted
to the Partners for written approval by the General Partners or the Liquidator,
the Partnership receives a Limited Liability Opinion, a Tax Opinion and an
Assignment Opinion with respect to such action or actions.

     Section 14.9  Voting and Approval Rights.

          (a)      Unless otherwise specified in this Agreement, Unitholders
shall have one vote for each Unit held by them.

          (b)      Only Unitholders who are Unitholders on the Record Date
determined pursuant to Section 14.2 shall be entitled to notice of, or to vote
at, a meeting of Unitholders. Only Unitholders who are Unitholders on the Record
Date determined pursuant to Section 14.8 shall be entitled to notice of, or to
give or withhold written approval of, any action for which written approvals are
solicited.

          (c)      With respect to Units that are held by a Nominee, such
Nominee shall, in exercising any voting or approval rights in respect of such
Units on any matter, vote such Units or give or withhold written approval with
respect to such Units at the direction of the Person which beneficially owns
such Units, and the Partnership shall be entitled to assume such Nominee is so
acting without further inquiry.

          (d)      Each Unitholder entitled to vote at a meeting of Unitholders
or to give or withhold written approval of any action may authorize another
Person to act for such Unitholder by proxy. A duly executed proxy shall be
irrevocable if it states that it is irrevocable and if, and only so long as, it
is coupled with an interest sufficient in law to support an irrevocable power. A
proxy may be made irrevocable regardless of whether the interest with which it
is coupled is an interest in the Unit itself or an interest in the Partnership
generally.

     Section 14.10 Amendments to Be Adopted Solely by the General Partners.

          The General Partners, without the approval of any Limited Partner, may
amend any provision of this Agreement to reflect:

                   (i)   a change in the name of the Partnership or the location
of the principal place of business of the Partnership;

                                       47
<PAGE>
 
          (ii)  the admission, substitution, withdrawal or removal of
Partners in accordance with this Agreement;

          (iii) a change that the General Partners determine is appropriate
in order to qualify the Partnership as a limited partnership or a partnership in
which the Limited Partners have limited liability under the laws of any state or
to ensure that the Partnership will not be treated as a corporation or as an
association taxable as a corporation for federal income tax purposes;

          (iv)  a change that the General Partners determine: (A) does not
adversely affect the holders of any class or series of Units in any material
respect, (B) is appropriate in order to satisfy any requirement, condition or
guideline contained in any federal or state statute or any rule, regulation,
requirement, condition or guideline of any federal or state agency, (C) is
appropriate in order to facilitate the listing or trading of the Units on or
otherwise to comply with any rule, regulation, requirement, condition or
guideline of any National Securities Exchange, or (D) is necessary in order to
effect the purposes of this Agreement, or to cure or otherwise correct any
ambiguity, error or omission in any provision of this Agreement;

          (v)   the designations, preferences and relative participating,
optional or other special rights, powers and duties of any newly created class
or series of Units;

          (vi)  a change that the General Partners determine is appropriate
in connection with the creation or issuance of any class or series of Units,
other Equity Securities, or other Partnership securities; or

          (vii) a change that the General Partners determine is appropriate
in connection with any action taken pursuant to Article XVI.

     Section 14.11 Amendment Procedures.

      (a) All amendments to this Agreement, except those described in
Section 14.10, shall be adopted as follows:

          (i)   Any such amendment shall be proposed by the General Partners.

          (ii)  Any such amendment proposed by the General Partners shall be
effective upon its approval by Unitholders holding a majority of the outstanding
Units, voting as a single class; provided, however, that if (A) the proposed
amendment would materially and adversely affect the rights or preferences of
holders of any class or series of Units or other Partnership Interests, it must
also be approved by Partners holding a majority of the outstanding Units of such
class or series, or a majority in interest of such Partnership Interests, as the
case may be; or (B) the proposed amendment would change the percentage of Units
or other Partnership Interests required to take any action, it must also be
approved by Partners holding at 

                                       48
<PAGE>
 
least the percentage of Units or other Partnership Interests which would be
changed by the proposed amendment.

      (b) The General Partners shall notify all Unitholders upon final
approval or disapproval of any amendment proposed by the General Partners.


                                  ARTICLE XV
                      Indemnification and Related Matters

     Section 15.1 Indemnification.

      (a) The Partnership shall indemnify each Indemnitee and hold it
harmless from and against any and all losses, claims, damages, liabilities,
expenses (including legal fees and expenses), judgments, fines, settlements and
other amounts, whether joint or several (collectively "Expenses"), arising from,
based upon or incurred in connection with any and all claims, demands, actions,
suits or proceedings, civil, criminal, administrative or investigative, in which
the Indemnitee may be involved, or threatened to be involved, as a party or
otherwise, by reason of its status as an Indemnitee (collectively
"Proceedings"), if the Indemnitee acted or failed to act in good faith and in a
manner it reasonably believed to be in, or not opposed to, the best interests of
the Partnership and, with respect to any criminal proceeding, had no reasonable
cause to believe its conduct was unlawful. The termination of any Proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere, or
its equivalent, shall not, of itself, create a presumption that the Indemnitee
acted in a manner contrary to that specified in the preceding sentence;
provided, however, that neither Thomson nor any of its Affiliates shall be
entitled to indemnification hereunder to the extent that such Person shall be
entitled to indemnity under Section 11.2(a) of the Purchase and Option Agreement
dated as of July 24, 1990 by and among Thomson, Thomson McKinnon Inc., a
Delaware corporation, Thomson McKinnon Holdings Inc., a Delaware corporation,
Thomson McKinnon Securities Inc., a Delaware corporation, Thomson McKinnon Asset
Management Inc., a Delaware corporation, Thomson McKinnon Fund Distributors
Inc., a Delaware corporation, and the Partnership.

      (b) Excise taxes assessed on an Indemnitee with respect to an employee
benefit plan are Expenses, and any action or failure to act by such Indemnitee
in a manner it reasonably believed to be in, or not opposed to, the best
interests of such plan shall be conclusively deemed to be in, or not opposed to,
the best interests of the Partnership.

     Section 15.2 Indemnification Agreements.

          The Partnership may enter into an indemnification agreement with any
Indemnitee, which agreement may include, without limitation, some or all of the
following provisions:

                                       49
<PAGE>
 
          (i)   that such Indemnitee shall be indemnified as provided in
Section 15.1;

          (ii)  that if such Person is successful, on the merits or
otherwise, in any Proceeding, it shall be indemnified against all Expenses
actually and reasonably incurred by it or on its behalf in connection with any
Proceeding; that if such Indemnitee is not wholly successful in such Proceeding
but is successful, on the merits or otherwise, as to one or more but less than
all claims, issues or matters in such Proceeding, the Partnership shall
indemnify such Person against all Expenses actually and reasonably incurred by
it or on its behalf in connection with each successfully resolved claim, issue
or matter; and that, for these purposes, and without limitation, the termination
of any claim, issue or matter in such Proceeding by dismissal with or without
prejudice, shall be deemed to be a successful result as to such claim, issue or
matter;

          (iii) that the Partnership shall from time to time advance all
Expenses actually and reasonably incurred by or on behalf of such Indemnitee in
connection with any Proceeding, and that each such advance shall be made within
20 days after the receipt by the Partnership of a statement listing Expenses
incurred by such Person since the date of the last statement;

          (iv)  that such Indemnitee shall be presumed to be entitled to
indemnification under such agreement if such Person has properly submitted a
request for indemnification and that the Partnership shall have the burden of
proof to overcome that presumption; and

          (v)   that if the Person empowered or selected to determine whether
such Indemnitee is entitled to indemnification shall not have made such
determination within a stated period, such Indemnitee shall be entitled to such
indemnification, with such exceptions as may be provided in such agreement.

     Section 15.3 Indemnification Procedures.

       Except as otherwise provided in any agreement for indemnification
entered into pursuant to Section 15.2:

          (i)   If an Indemnitee receives notice of any Proceeding with respect
to which the Indemnitee may be entitled to indemnification under Section 15.1 or
such agreement, the Indemnitee shall promptly give notice to the Partnership of
such Proceeding. To the extent that delay in giving such notice, or failure to
give such notice, materially prejudices the Partnership, the Indemnitee shall
not be entitled to indemnification.

          (ii)  The Partnership shall from time to time advance all Expenses
actually and reasonably incurred by or on behalf of an Indemnitee in connection
with any Proceeding, upon receipt by the Partnership of an undertaking by or on
behalf of the Indemnitee 

                                       50
<PAGE>
 
to repay such advances if it shall be determined that the Indemnitee is not
entitled to be indemnified under Section 15.1 or such agreement.

          (iii) The Partnership may assume the defense of any Proceeding,
with counsel reasonably acceptable to the Indemnitee, by giving notice to the
Indemnitee (a "Defense Notice") of the Partnership's election to do so. In the
event that the Partnership so elects to assume the defense of a Proceeding, the
Partnership will not be liable to the Indemnitee for any attorney's fees or
expenses incurred by the Indemnitee with respect to the defense of such
Proceeding after the date of the Indemnitee's receipt of the Defense Notice,
provided that:

                (A) The Indemnitee shall continue to have the right to employ
counsel in any such Proceeding at the Indemnitee's own expense; and

                (B) If (1) the employment of counsel by the Indemnitee has
previously been authorized in writing by the Partnership, or (2) the Partnership
shall have reasonably concluded, and shall have given notice to the Indemnitee,
that there may be a conflict of interest between the Partnership and the
Indemnitee in the conduct of such defense, or (3) the Partnership shall not, in
fact, have employed counsel to assume the defense of such Proceeding, then the
fees and expenses of the Indemnitee's counsel shall be paid by the Partnership
in accordance with Section 15.1 or such agreement.

          (iv)  The Partnership may, without the consent of the Indemnitee,
settle any claim in any Proceeding for which it is obligated to provide
indemnification under Section 15.1 or such agreement, and, as a condition to the
Indemnitee's receipt of such indemnification, the Indemnitee shall take all such
actions required to cooperate in effecting such settlement; provided, however,
that the Partnership shall not settle any claim in any manner that would impose
any penalty or limitation on the Indemnitee without the Indemnitee's written
consent (which may not be unreasonably withheld or delayed).

     Section 15.4 Insurance.

          The Partnership may purchase and maintain insurance for the benefit of
one or more Indemnitees against any Expenses incurred by them, regardless of
whether the Partnership would have the power to indemnify such Indemnitees
against such Expenses under this Agreement.

     Section 15.5 Source of Payment.

          Any indemnification under this Article XV shall be paid solely out of
any insurance purchased pursuant to Section 15.4, or Partnership Assets, and the
General Partners, Limited Partners and their Affiliates, shall have no liability
for any such indemnification.

     Section 15.6 Scope of Indemnification.

                                       51
<PAGE>
 
          The indemnification provided by Section 15.1 (i) shall be in addition
to any other rights to which an Indemnitee may be entitled under any agreement,
pursuant to any vote of the Unitholders, as a matter of law or otherwise, (ii)
shall continue as to an Indemnitee which has ceased to serve in a capacity for
which the Indemnitee is entitled to indemnification, (iii) shall inure to the
benefit of the heirs, successors, assigns, administrators and personal
representatives of the Indemnitee, and (iv) shall not be deemed to create any
right to indemnification for the benefit of any other Persons.

     Section 15.7 Effect of Amendments.

          No amendment of this Agreement shall limit or otherwise adversely
affect the right of any Indemnitee to indemnification for any act, or failure to
act, which occurred prior to the adoption and effectiveness of the amendment

     Section 15.8 Limitations on Liability of Indemnitees.

          (a) The General Partners shall not be liable to the Partnership or any
Partner for any action or failure to act on the part of any Delegate or any
committee, subcommittee or officer appointed by such Delegate, so long as the
General Partners appointed such Delegate in good faith and with reasonable care.
Neither a Delegate nor its members, if any, shall be liable to the Partnership
or any Partner for any action or failure to act on the part of any committee,
subcommittee or officer appointed by such Delegate in good faith and with
reasonable care.

          (b) An Indemnitee shall not be liable to the Partnership or any
Partner for breach of fiduciary duty (including breach of any duty of care or
any duty of loyalty) to the Partnership or any Partner unless it is proved by
clear and convincing evidence that the Indemnitee's action or failure to act was
undertaken with deliberate intent to cause injury to the Partnership or was
undertaken with reckless disregard for the best interests of the Partnership.

          (c) An Indemnitee may rely upon and shall be protected and shall incur
no liability in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
order, bond, debenture or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties. An
Indemnitee shall not be liable to the Partnership, any Partner or any other
Indemnitee for, and shall be protected in, acting or refraining from acting, in
reliance in good faith on the provisions of this Agreement, and the exercise in
good faith of any of the powers or rights granted to an Indemnitee by this
Agreement or pursuant to the delegation of power and authority permitted by this
Agreement, shall not constitute a breach of fiduciary duty to the Partnership,
any Partner or any other Indemnitee.

          (d) An Indemnitee may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers and other consultants and
advisers selected by it, 

                                       52
<PAGE>
 
and any opinion of any such Person as to matters that such Indemnitee reasonably
believes to be within such Person's professional or expert competence shall be
full and complete authorization and protection in respect to any action taken or
suffered or omitted in good faith and in accordance with such opinion.

          (e) In taking an action or making a determination pursuant to this
Agreement, the General Partners or their Delegates shall take into account such
factors as they consider to be appropriate in the circumstances and shall have
no duty or obligation to take any other factors into account. If any such action
or determination is required to be taken or made in "good faith," or under
another express standard, the General Partners or their Delegates shall take
such action or make such determination under such express standard and shall not
be subject to any other or different standards. Any action or determination
required to be taken or made by the General Partners or their Delegates in "good
faith" shall be presumed to meet that standard unless it is proved by clear and
convincing evidence that such action or determination was taken or made in bad
faith.

          (f) If any transaction contemplated by this Agreement is required to
be "fair" to the Partnership, the fairness of such transaction shall be
determined in context with all similar or related transactions and with all
other transactions and relationships among the Persons involved and their
respective Affiliates.


                                  ARTICLE XVI
                                 Restructuring

     Section 16.1 Power of General Partners to Effect a Restructuring.

          (a) If at any time the General Partners determine that as a result
of (i) the enactment (or imminent enactment) of any legislation, (ii) the
publication of any temporary or final regulation by the United States Department
of the Treasury or any ruling by the Internal Revenue Service, (iii) a judicial
decision, or (iv) otherwise (including the cumulative effect of Transfers of
Units or admissions of additional Limited Partners), there is a substantial risk
of an Adverse Partnership Tax Event or a Tax Realization Event, then the General
Partners may take any and all actions that the General Partners deem appropriate
to accomplish one or more Restructurings. Such actions authorized pursuant to
this Section 16.1(a) include, but are not limited to:

              (i)   The creation of one or more Business Entities controlled by
the General Partners, Affiliates of the General Partners or Affiliates of the
Partnership.

              (ii)  The transfer of all or any part of the business of the
Partnership or the Partnership Assets to one or more existing or newly-created
Business Entities in exchange for 

                                       53
<PAGE>
 
interests in such Business Entities, which interests may be subject to
substantial restrictions on transfer.

              (iii) The initiation of exchange or redemption transactions which
will permit and may automatically effect, without the consent of any Limited
Partner, the exchange of some or all outstanding LP Units for interests in one
or more existing or newly-created Business Entities which hold, directly or
indirectly, Partnership Interests or interests in all or any part of the
business of the Partnership or the Partnership Assets, including without
limitation one or more Public General Partners.

              (iv)  The imposition of substantial restrictions on the
transferability of some or all of the LP Units (or interests in one or more
Successor Entities) for both limited and extended periods of time, which
restrictions may provide for penalties (including forfeiture of Units) for
attempted or purported Transfers in violation of such restrictions.

              (v)   Causing the Partnership and any one or more Successor
Entities to enter into agreements governing their relationships following the
Restructuring, on terms and conditions determined by the General Partners,
including without limitation agreements providing for (A) the issuance and sale
by a Successor Entity of its securities and the contribution of the proceeds of
such issuance and sale to the Partnership, in exchange for Units or other
Partnership securities; (B) the acquisition by a Successor Entity of businesses
or assets and the contribution of such businesses or assets to the Partnership
in exchange for Units; (C) the adoption by a Successor Entity of one or more
employee benefit plans involving the issuance of its securities, the assumption
by such Successor Entity of the outstanding employee benefit plans of the
Partnership, and contribution of the proceeds of issuance and sale of securities
under any employee benefit plans of such Successor Entity to the Partnership, in
exchange for Units; and (D) the exchange of outstanding Units for securities of
a Successor Entity upon request by the holders of such Units, the registration
of such securities under federal and state securities laws in connection with a
public offering, and the concomitant listing of such securities on a National
Securities Exchange.

          (b) The power and authority of the General Partners to effect (or not
to effect) one or more Restructurings was a bargained-for and material condition
of the willingness of the General Partners and their Affiliates to enter into
the Partnership Agreement. The power and authority of the General Partners to
effect (or not to effect) one or more Restructurings includes the power and
authority to effect one or more Restructurings that result in benefits to one or
more Partners or their Affiliates (including without limitation the General
Partners or their Affiliates) that are not enjoyed by all Partners, and that may
result in disadvantageous consequences to one or more Partners that are not
suffered by all Partners or their Affiliates (including without limitation the
General Partners or their Affiliates). No Limited Partner shall have any cause
of action against, or right to receive any compensation from, the Partnership,
the General Partners or their Affiliates or any other Limited Partner or its
Affiliates, as a result of or in respect of (i) any Restructuring or the
disparate effects thereof on any one or more Partners, (ii) the failure of 

                                       54
<PAGE>
 
the General Partners to effect any one or more Restructurings, or (iii) the
General Partners' determination to effect a particular Restructuring or
Restructurings instead of any other Restructuring or Restructurings, unless it
is proved by clear and convincing evidence that the action or failure to act of
the General Partners involved an act or omission undertaken with deliberate
intent to cause injury to the Partnership or was undertaken with reckless
disregard for the best interests of the Partnership.

     Section 16.2 Consent to Actions Taken in Connection with Restructuring.

          Each of the Limited Partners approves, ratifies and confirms the
execution, delivery and performance by the General Partners of all documents and
instruments, and the taking of all actions and the doing of all things, deemed
appropriate or necessary by the General Partners in connection with any
Restructuring pursuant to this Article XVI, and agrees that the General Partners
are authorized to execute, deliver and perform such documents and instruments,
and to take such actions and do such things, without the approval of the Limited
Partners.


                                 ARTICLE XVII
                          Dissolution and Liquidation

     Section 17.1 Dissolution.

          The Partnership shall be dissolved and its affairs shall be wound up
upon:

               (i)    the expiration of its term as provided in Section 2.5;

               (ii)   the written determination by the General Partners that
projected future revenues of the Partnership will be insufficient to enable
payment of projected Partnership costs and expenses or, if sufficient, will be
such that continued operation of the Partnership is not in the best interests of
the Partners;

               (iii)  the written election of the General Partners to dissolve
the Partnership following the occurrence of an Adverse Partnership Tax Event;

               (iv)   the written election of the General Partners to dissolve
the Partnership, which is approved by Unitholders holding a majority of the
outstanding Units held by Persons other than the General Partners and their
Affiliates, voting as a single class;

               (v)    the sale of all or substantially all of the Partnership
Assets, other than in connection with a Restructuring;

               (vi)   the written consent of all of the Partners;

                                       55
<PAGE>
 
               (vii)  the occurrence of an Event of Withdrawal, unless (A) the
remaining General Partners carry on the business of the Partnership, or (B)
within 90 days after such Event of Withdrawal, not less than a majority in
interest of the remaining Partners agree in writing to continue the business of
the Partnership and to the appointment, effective as of the date of such Event
of Withdrawal, of one or more additional General Partners if necessary or
desired, and the Partnership receives a Limited Liability Opinion, a Tax Opinion
and an Assignment Opinion with respect to such continuation: or

               (viii) entry of a decree of dissolution under the Delaware Act.

     Section 17.2 Reconstitution.

          Within 180 days following an Event of Withdrawal that results in the
dissolution of the Partnership, a majority in interest of the remaining Partners
may agree in writing to reconstitute and continue the business of the
Partnership by forming a Reconstituted Partnership on the same terms as are set
forth in this Agreement and to appoint one or more general partners of the
Reconstituted Partnership; provided, however, that no such agreement shall be
effective unless the Partnership has received a Limited Liability Opinion, a Tax
Opinion and an Assignment Opinion with respect to such reconstitution and
continuance. If such an agreement is duly and timely made, all of the Limited
Partners of the Partnership shall continue as limited partners of the
Reconstituted Partnership.

     Section 17.3 Liquidator; Liquidation and Distribution.

          (a) Upon dissolution of the Partnership, unless the Partnership is
reconstituted pursuant to Section 17.2, the remaining General Partners, if any,
or if there is no remaining General Partner, the Former General Partner, if any,
whose withdrawal as a General Partner pursuant to Section 13.1(b) resulted in
the dissolution, or if there is no such Former General Partner, a liquidator or
liquidating committee Approved by the Unitholders, shall be the Liquidator. The
Liquidator (if not a General Partner) shall be entitled to receive such
compensation for its services as may be Approved by the Unitholders. The
Liquidator shall agree not to resign at any time without 15 days' prior written
notice and (if not a General Partner or Former General Partner) may be removed
at any time, with or without cause, by notice of removal Approved by the
Unitholders. Upon resignation or removal of the Liquidator, a successor
Liquidator (who shall have and succeed to all rights, powers and duties of the
original Liquidator) shall within 30 days thereafter be Approved by the
Unitholders.

          (b) Upon dissolution of the Partnership and until the filing of a
Certificate of Cancellation, the Liquidator may, in the name of and for and on
behalf of the Partnership, prosecute and defend suits, whether civil, criminal
or administrative, gradually settle and close the business of the Partnership,
dispose of and convey the Partnership Assets, discharge or make reasonable
provision for all Partnership liabilities, and distribute to the Partners any
remaining Partnership Assets, all without affecting the liability of the Limited
Partners and without 

                                       56
<PAGE>
 
imposing the liability of a general partner on the Liquidator (if not a General
Partner). A reasonable time shall be allowed for the winding up of the
Partnership so as to minimize any losses otherwise attendant upon such winding
up.

          (c) Upon the winding up of the Partnership, the Partnership Assets
shall be distributed in the following order of priority, unless otherwise
provided by law:

              (i)     to creditors of the Partnership, including Partners who
are creditors, to the extent otherwise permitted by law, in satisfaction of
Partnership liabilities (whether by payment or the making of reasonable
provision for payment) other than liabilities for which reasonable provision for
payment has been made and liabilities for distributions to Partners and former
Partners pursuant to Section 8.1 or 8.3 with respect to fiscal quarters ending
before the dissolution of the Partnership;

Assets for contingent liabilities in an amount, if any, determined by the
Liquidator;

creditors, and may distribute to the Unitholders, in lieu of cash, as tenants in
common and in accordance with the provisions of Section 17.3(c), undivided
interests in such Partnership Assets. Any such distribution in kind shall be
subject to such conditions relating to the management and disposition of the

Liquidator shall determine the fair market value of any Partnership Assets
distributed in kind.

               RESTRUCTURING CONTRIBUTION AND ISSUANCE AGREEMENT
                                        

          This Restructuring Contribution and Issuance Agreement dated as of
December 31, 1997 (this "Agreement"), is entered into by and between the Public
Unitholders of PIMCO Advisors L.P., a Delaware limited partnership ("PIMCO
Advisors"), Oppenheimer Capital, L.P., a Delaware limited partnership ("Opcap
LP"), and PIMCO Advisors.  Initially capitalized terms used herein and not
otherwise defined herein are defined in the Amended and Restated Agreement of
Limited Partnership of PIMCO Advisors L.P. dated October 31, 1997 (the "PIMCO
Advisors Partnership Agreement").

                                   RECITALS:

          WHEREAS, pursuant to Section 16.1 of the PIMCO Advisors Partnership
Agreement, if the General Partners of PIMCO Advisors determine that as a result
of, among other things, the enactment of legislation, there is a substantial
risk of an Adverse Partnership Tax Event or a Tax Realization Event, the General
Partners have the authority to effect one or more Restructurings of PIMCO
Advisors, including, but not limited to, (a) the creation of one or more
Business Entities controlled by the General Partners, Affiliates of the General
Partners or Affiliates of PIMCO Advisors, (b) the transfer of all or any part of
the business or assets of PIMCO Advisors to one or more existing or newly-
created Business Entities in exchange for interests in such Business Entities,
(c) the initiation of exchange or redemption transactions which will permit and
may automatically effect, without the consent of any Limited Partner, the
exchange of some or all of the PIMCO Advisors LP Units for interests in one or
more existing or newly-created Business Entities, (d) the imposition of
substantial restrictions on the transferability of some or all of the PIMCO
Advisors LP Units, and (e) causing PIMCO Advisors and any one or more Successor
Entities to enter into agreements governing their relationships following the
restructuring, on terms and conditions determined by the General Partners,
including agreements relating to the issuance of and sale of securities of the
Successor Entity, the acquisition by a Successor Entity of businesses or assets
and the contribution of such businesses or assets to PIMCO Advisors in exchange
for PIMCO Advisors Units, the adoption by a Successor Entity of employee benefit
plans for the benefit of PIMCO Advisors employees and the exchange of
outstanding PIMCO Advisors units for securities of the Successor Entity upon
request by the holders of PIMCO Advisors Units;

          WHEREAS, pursuant to Section 16.3 of the PIMCO Advisors Partnership
Agreement, the General Partners have the authority to execute, deliver and
perform all documents and instruments, and to take all actions and do such
things that the General Partners deem necessary and appropriate in connection
with any Restructuring pursuant to Article XVI of the PIMCO Advisors Partnership
Agreement, without the approval of the Limited Partners, including the Public
Unitholders (the "Authorization");

          WHEREAS, the General Partners of PIMCO Advisors have determined that
as a result of legislation enacted as part of the Taxpayer Relief Act of 1997,
there will be an Adverse Partnership Tax Event unless the PIMCO Advisors Class A
LP Units cease to be publicly traded prior to January 1, 1998, and have
determined it appropriate to effect a Restructuring of PIMCO Advisors wherein
each Public Unitholder will contribute its PIMCO Advisors LP Units to Opcap LP
in exchange for an equal number of units of limited partner interest in Opcap LP
("Opcap LP Units");
<PAGE>
 
          WHEREAS, the restructuring will result in each Public Unitholder
ceasing to be a Limited Partner of PIMCO Advisors and being admitted as a
limited partner of Opcap LP;

          WHEREAS, pursuant to Sections 9.01 and 13.06 of the Amended and
Restated Agreement of Limited Partnership of Oppenheimer Capital, L.P. dated
March 14, 1991, as amended (the "Opcap LP Partnership Agreement"), the General
Partner of Opcap LP has the authority to issue additional limited partner
interests to Opcap LP and admit additional limited partners to Opcap LP upon
making an Assignment Determination and a Tax Determination, as those terms are
defined in the Opcap LP Partnership Agreement, and upon obtaining an opinion of
a nationally recognized investment banking firm that such issuance is fair to
the limited partners who are not affiliates of the General Partner from a
financial point of view (a "Fairness Opinion");

          WHEREAS, the General Partner of Opcap LP has made an Assignment
Determination and a Tax Determination, and  has obtained a Fairness Opinion from
Lazard Freres & Company LLC;

          WHEREAS, PIMCO Partners G.P., a California General Partnership
("PGP"), and Opcap LP, as General Partners of PIMCO Advisors and pursuant to the
power, authority and authorization granted to them under the PIMCO Advisors
Partnership Agreement including, without limitation, Sections 16.1 and 16.3,
desire to cause the PIMCO Advisors LP Units held by the Public Unitholders to be
contributed to Opcap LP in exchange for an equal number of Opcap LP Units; and

          WHEREAS, PGP, as the General Partner of Opcap LP, desires to cause
Opcap LP to accept contributions from the Public Unitholders of their PIMCO
Advisors LP Units in exchange for issuance of an equal number of Opcap LP Units

to such units in the PIMCO Advisors Partnership Agreement.  At the Effective

partner units shall be issued to Opcap LP as of the Effective Time.

Summary.

          1.1.2   The Building and the Project.  The Building is part of an
                  ----------------------------                             
office project known as "Pacific Financial Plaza" which contains two seven-story
office buildings and a two-level detached commercial structure (individually,
the other buildings shall be a "Project Building" or collectively, the "Project
Buildings").  The term "Project," as used in this Lease, shall mean (i) the
Building, the Project Buildings and the "Common Areas," as that term is defined
in Section 1.1.3 below, (ii) the land (which is improved with landscaping,
   -------------                                                          
parking facilities and other improvements) upon which the Building, the Project
Buildings and the Common Areas are located and (iii) at Landlord's discretion,
any additional real property, areas, buildings or other improvements added
thereto.  Tenant acknowledges that Landlord has made no representation or
warranty regarding the condition of the Project except as specifically set forth
in the Lease.

          1.1.3   Common Areas.  Tenant shall have the non-exclusive right to
                  ------------                                               
use in common with other tenants in the Project, and subject to the rules,
regulations and restrictions attached hereto as Exhibit B (the "Rules and
                                                ---------                
Regulations"), those portions of the Project which are provided, from time to
time, for use in common by Landlord, Tenant and any other tenants of the Project
(such areas designated by Landlord, in its discretion, are collectively referred
to herein as the "Common Areas").  The Common Areas shall consist of the
"Project Common Areas" and the "Building Common Areas."  The term "Project
Common Areas," as used in this Lease, shall mean all common areas in the Project
other than the Building

                                       1
<PAGE>
 
Common Areas, including, without limitation, any parking facilities, fixtures,
systems, signs, facilities, gardens, parks or other landscaping used in
connection with the Project, and may include any city sidewalks adjacent to the
Project, pedestrian walkway system, whether above or below grade, park or other
facilities open to the general public and roadways, sidewalks, walkways,
parkways, driveways and landscape areas appurtenant to the Project. The term
"Building Common Areas," as used in this Lease, shall mean the portions of the
Common Areas located within the Building and may include, without limitation,
the common entrances, lobbies, restrooms, elevators, stairways and accessways,
loading docks, ramps, drives, platforms, passageways, serviceways, common pipes,
conduits, wires, equipment, loading and unloading areas, and trash areas
servicing the Building. The manner in which the Common Areas are maintained and
operated shall be at the discretion of Landlord, but shall be maintained in a
condition consistent with a class A office project. Landlord reserves the right
without notice to Tenant to make alterations or additions to or to change the
location of elements of the Project and the Common Areas; provided however,
Landlord shall not make any such alterations, additions or changes to the Common
Areas which prevent access to the Premises for Tenant's employees and invitees
or Tenant's use of the Premises for the uses permitted hereunder.

          1.1.4   Partial Termination Option.  Notwithstanding any provision of
                  --------------------------                                   
this Lease to the contrary but subject to the conditions set forth below, Tenant
shall have the one-time option ("Termination Option") to terminate the Lease as
to the "Termination Portion" of the Premises (as defined below), which
termination shall, subject to the conditions set forth in this Section 1.1.4, be
                                                               -------------    
effective as of March 31, 2002 (the "Termination Date"). The term "Termination
Portion" of the Premises shall mean that portion of the Premises designated as
the "Termination Portion" on Exhibit A attached hereto, which is located within
                             ---------                                         
Suite 550 of the 800 Building.  Conditions to Tenant's exercise of the
Termination Option shall be that (i) Tenant must provide Landlord with written
notification ("Termination Notice") of Tenant's exercise of said Termination
Option at least twelve (12) months prior to the Termination Date, and (ii)
Tenant shall pay to Landlord concurrently with Tenant's delivery of the
Termination Notice, in consideration of Landlord's agreement to so terminate
this Lease as to the Termination Portion, an amount ("Termination Fee") equal to
the sum of (a) six (6) monthly installments of Annual Basic Rent for the
Termination Portion of the Premises (calculated at Two Dollars and Sixty-Five
Cents ($2.65) per rentable square foot of the Termination Portion per month),
plus (b) the unamortized balance, as of the Termination Date, of the leasing
fees allocable to the Termination Portion paid by Landlord to the Brokers
referenced in Section 12 of the Summary, with such amortization to be calculated
on a straight line basis over the initial eighty-four (84) month Lease Term,
plus (c) the unamortized balance, as of the Termination Date, of the Thirty
Dollar ($30.00) per usable square foot Tenant Improvement Allowance allocable to
the Termination Portion, with such amortization to be calculated over the
eighty-four (84) month period from April 1, 1998 until March 30, 2005, based
upon equal monthly payments of principal and interest for such amortization
period, with interest imputed on the outstanding principal balance at twelve
percent (12%) per annum.  If Tenant properly and timely exercises the
Termination Option, the Lease shall expire as to the Termination Portion of the
Premises as of the Termination Date.

          1.1.5   Must-Take Space.  Effective upon the applicable "Must-Take
                  ---------------                                           
Space Commencement Date" (as defined below), the "Must-Take Space" (as defined
below) shall be added to and become and be deemed a part of the Premises for all
purposes of this Lease.  The "Must Take Space" consists of "Must-Take Space I"
and "Must-Take Space II."  "Must-Take Space I" means an aggregate of twenty-six
thousand eight hundred thirty-two (26,832) rentable square feet of space
consisting of Suites 550 and 600 in the 800 Building, containing eight thousand
one hundred fifty (8,150) and eighteen thousand six hundred eighty-two (18,682)
rentable square feet, respectively.  "Must-Take Space II" means an aggregate of
eight thousand six hundred eighteen (8,618) rentable square feet of space
consisting of Suite 100 (5,609 rentable square feet) and Suite 150 (3,009
rentable square feet), each of which Suites is located in the 800 Building.

                                       2
<PAGE>
 
            As of the date of execution of this Lease, Must-Take Space I is
leased by Federal Express Corporation under a lease (the "Fed Ex Lease") having
an expiration date of August 31, 1998 and Must-Take Space II is leased by
California Federal Bank (the "Cal Fed Lease"), a portion of which (Suite 100) is
occupied by an affiliate of Tenant, and the balance of which is occupied by a
subtenant not affiliated with Tenant, each under a sublease under the Cal Fed
Lease. The expiration date of the Cal Fed Lease is June 1, 2002, subject to an
option to extend the term of the Cal Fed Lease to May 31, 2012. Landlord agrees
to use Landlord's commercially reasonable efforts to terminate the Fed Ex Lease
as soon as reasonably practicable. The parties do not contemplate that Landlord
will be able to terminate the Cal Fed Lease. Assuming that Landlord is
successful in arranging an early termination of the Fed Ex Lease, the estimated
"Must-Take Space Commencement Date" (that is, the date Landlord tenders
possession of the applicable Must-Take Space to Tenant) is (i) April 15, 1998
for Must-Take Space I. The estimated "Must-Take Space Commencement Date" for
Must-Take Space II is immediately upon termination of the Cal Fed Lease with
respect to the applicable Must-Take Space II. Tenant acknowledges and agrees
that Tenant shall accept the Must Take Space in its OAS ISO condition and that
Tenant may construct improvements in the Must Take Space pursuant to the
terms of the Tenant Work Letter attached hereto as Exhibit D; provided
                                                   ---------
however, that the Tenant Improvement Allowance shall be Thirty Dollars
($30.00) for all Must-Take Space other than Suite 100 of Must-Take Space II, for
                                 ----- ----                                     
which Suite 100 the Tenant Improvement Allowance shall be Five Dollars ($5.00)
per usable square foot.

            1.1.5.1  Must-Take Space Rent Commencement Date.  Tenant's
                     --------------------------------------           
obligation to pay Base Rent for the Must-Take Space shall commence on the
applicable "Must-Take Space Rent Commencement Date" (as defined below), provided
that Landlord hereby agrees to waive the payment of Base Rent for five thousand
nine hundred forty-six (5,946) rentable square feet of Must Take Space I for the
first six (6) months after the Must-Take Space Rent Commencement Date for Must
Take Space I. The "Must-Take Space Rent Commencement Date" shall be that date
which is the earlier to occur of the date Tenant commences to conduct business
in the applicable Must-Take Space or sixty (60) days after the Must-Take Space
Commencement Date (that is, the date Landlord tenders possession of the
applicable Must-Take Space to Tenant vacant and free of the existing leases with
respect thereto).

            1.1.5.2  Must-Take Terms.  Effective as of the Must-Take Space
                   ---------------                                      
Commencement Date, the Must-Take Space shall be added to and become and be
deemed a part of the Premises, and all adjustments shall be made in the Lease
which are appropriate to reflect such addition to the Premises; provided
however, that Tenant's obligation to pay Base Rent, the proportionate increase
in Tenant's Share and the number of Tenant's parking passes which Tenant is
entitled to purchase shall not occur until the applicable Must-Take Space Rent
Commencement Date.  The term for the Must-Take Space shall be coterminous with
the remaining Term of the Lease and the monthly Base Rent applicable to the
Must-Take Space shall be the Base Rent on a per rentable square foot basis which
is applicable to the Premises, from time to time, during the remaining Lease
Term.  All other terms and provisions of the Lease shall also be applicable to
the Must-Take Space.

    1.1.6   Right of First Offer.  Tenant shall have the right of first

offer during the Lease Term to lease any available space other than space leased
to Tenant consisting of:  (i) at least two thousand (2,000) rentable square feet
in the 840 Building (the "840 First Offer Space"); and (ii) any space on the
third (3rd), fourth (4th), or fifth (5th) floors of the 800 Building (the "800
First Offer Space"), pursuant to the following terms of this Section 1.1.6.
                                                             -------------  
Space in the Building shall be considered to be "available" if no other tenant
is leasing such space, has the right to lease such space, to expand into such
space, or to extend the term of its lease for such space and with regard to
space which is leased by a tenant, such space shall be considered to become
available upon expiration of the term of such tenant's lease of such space only
if Landlord and such tenant fail to reach agreement for the extension of the
term of such tenant's lease, whether pursuant to a formal extension option
contained within such tenant's lease or, with respect to space in the Building
other than space located on the fifth floor of the 800 Building, otherwise, in
either case within thirty (30) days after such expiration date or such longer
period of time as

                                       3

may be necessary in order to complete any arbitration, appraisal or similar
procedure set forth in a formal extension option. The 840 First Offer Space and
the 800 First Offer Space are sometimes referred to herein collectively as the
"First Offer Space." If Tenant objects to Landlord's determination of the Fair
Market Rental Value for any First Offer Space within the applicable time period
set forth below, then Tenant may elect to lease such space within such period
and the Fair Market Rental Value shall be determined by arbitration in the
manner provided in Section 2.2.3.1 through Section 2.2.3.7 hereof. Landlord and
                   ---------------         ---------------
Tenant agree to use their good faith efforts to agree upon the Fair Market
Rental Value for the applicable First Offer Space during the applicable period
prior to arbitration being instituted.

     1.1.6.1  Procedure for Offer.
              ------------------- 

              1.1.6.1.1    840 First Offer Space.  Landlord agrees that
                           ---------------------                       
during the Lease Term, Landlord shall deliver written notice to Tenant (the "840
First Offer Notice") prior to the first time that any 840 First Offer Space
                                  -----                                    
shall hereafter become available for lease to third parties.  The 840 First
Offer Notice shall describe the space which is available (including, without
limitation, Landlord's determination of the rentable square footage thereof),
and shall set forth (i) the anticipated date on which the applicable 840 First
Offer Space will be available for lease by Tenant and the commencement date
therefor, and (ii) Landlord's determination of Fair Market Rental Value for such
840 First Offer Space.  If Tenant is interested in leasing the 840 First Offer
Space, Landlord and Tenant shall, for a period of ten (10) days after the date
of Tenant's receipt of the 840 First Offer Notice with respect to such space,
attempt to reach agreement as to the terms for Tenant's lease of such space.  If
Landlord and Tenant are unable to reach agreement within such ten (10) day
period, then Landlord shall be free to lease all or a portion of such space to
any third party upon any terms; provided however, with respect only to space
located on the fourth floor of the 840 Building, if Landlord does not enter into
a lease with a third party within one hundred twenty (120) days following the
expiration of such ten (10) day period, or if Landlord is not pursuing lease
negotiations with a third party tenant at the next time Tenant exercises its
First Offer right under this Section 1.1.6.1.1, then Tenant's First Offer right
                             -----------------                                 
set forth herein shall be reinstated and the procedures of this Section
                                                                -------
1.1.6.1.1 shall be repeated.
- ---------                   

              1.1.6.1.2    800 First Offer Space.  Landlord agrees that during
                           ---------------------                       
the Lease Term, Landlord shall deliver written notice to Tenant (the "800
First Offer Notice") up to eight (8) months but not less than ninety (90) days
prior to each time that any 800 First Offer Space shall hereafter become
available for lease to third parties.  The 800 First Offer Notice shall describe
the space which is available (including, without limitation, Landlord's
determination of the rentable square footage thereof, the anticipated date on
which the 800 First Offer Space will be available for lease by Tenant and the
commencement date therefor), and shall set forth Landlord's determination of
Fair Market Rental Value with respect to such space.  Within sixty (60) days
after Tenant's receipt of each 800 First Offer Notice (the "800 First Offer
Response Date"), Tenant must give Landlord written notice pursuant to which
Tenant either (i) elects to lease the 800 First Offer Space at Fair Market
Rental Value for a term coterminous with the Term hereof; or (ii) elects not to
lease such 800 First Offer Space.  If Tenant does not so respond in writing to
Landlord's notice on or before the 800 First Offer Response Date, or has
responded in accordance with clause (ii) above, Landlord may lease the 800 First
Offer Space to any third party on terms comparable to those offered to Tenant,
as conclusively evidenced by execution of a lease with a third party tenant;
provided however, if Landlord does not enter into a lease with a third party
within one hundred twenty (120) days following the earlier of Landlord's receipt
of Tenant's response to Landlord's notice or the 800 First Offer Response Date,
or if Landlord is not pursuing lease negotiations with a third party tenant at
the next time Tenant exercises its First Offer right under this Section
                                                                -------
1.1.6.1.2, then Tenant's First Offer right set forth herein shall be reinstated
- ---------                                                                      
and the procedures of this Section 1.1.6.1.2 shall be repeated.  Tenant's
                           -----------------                             
obligation to pay Rent for the First Offer Space shall commence upon the earlier
of the sixtieth (60th) day following the date Landlord tenders possession of the
applicable First Offer Space to Tenant or the date Tenant commences to do
business in such space.  Notwithstanding

                                       4
<PAGE>
 
anything contained herein to the contrary, the 800 First Offer Right may not be
exercised during the last twelve (12) months of the Term (as adjusted and
extended from time to time).

              1.1.6.2   Suspension of Right of First Offer.  At Landlord's
                        ----------------------------------                
option, Tenant shall not have the right to lease the First Offer Space as
provided in this Section 1.1.6 so long as Tenant, as of the date of receipt of
                 -------------                                                
the First Offer Notice by Tenant, or as of the date of delivery of such
First Offer Space to Tenant, is in material, monetary default under this Lease
after expiration of all applicable cure periods.

the premises leased by Tenant), and shall only be available to Tenant when
Tenant is in actual possession and physical occupancy of at least ninety-five
percent (95%) of the entire space leased by Tenant within the Building other
than the Termination Portion in the event Tenant has exercised Tenant's
Termination Option pursuant to Section 1.1.4 of this Lease.

the right to lease greater than an aggregate total of ninety-nine thousand
(99,000) rentable square feet in the Building, including without limitation, any
space which has been assigned to or subleased by Tenant or Affiliates of Tenant,
but excluding all storage space held by Tenant in the Building.  This Section

     1.2  Verification of Rentable Square Feet of Premises and Building.  For

purposes of this Lease, "rentable square feet" shall be calculated using as a
guideline the Standard Method for Measuring Floor Area in Office Buildings, ANSI

rentable square footage of the Building and other buildings in the Project shall
include all of (and the rentable square footage of the Premises therefore shall
include a portion of) (i) the Building Common Areas and (ii) the occupied space
of the portion of the Project dedicated to the service of the Project.  The
rentable square feet of the Premises, Building and the Project have been
measured by Landlord's space accountant and are set forth in the Summary and the
measurements set forth in the Summary shall be conclusive and binding upon the
parties and not subject to remeasurement.

     2.2  Extension of Initial Term.  Tenant shall have the right, at Tenant's
          -------------------------                                           
option, to extend the Lease Term for one (1) renewal term of five (5) years
commencing on April 1, 2005 and expiring on March 31, 2010 (the "Option Term").
Tenant's option to extend the term of the Lease shall apply to the entire
Premises leased by Tenant as of the last day of the initial Lease Term,
including without limitation all Must-Take Space and First Offer Space actually
added to the Premises in such Building, exclusive of the Termination Portion if
Tenant has exercised Tenant's Termination Option pursuant to Section 1.1.4 of
                                                             -------------   
this Lease; provided however, Tenant, in Tenant's sole discretion, may elect to
extend the term of this Lease only with respect to all of such Premises leased
by Tenant as of the last day of the initial Lease Term in either the 800
Building or the 840 Building. The total rent (collectively, "Rent") payable by
Tenant during the Option Term (the "Option Rent") shall be equal to the "Fair
Market Rental Value" for the Premises. The term "Fair Market Rental Value" shall
mean the per rentable square foot rental rate per month (including operating
cost and tax payments and considering any "base year" or "expense stop"
applicable thereto), including all escalations at which, as of the commencement
of the Option Term, landlords are leasing non-renewal, non-sublease, non-
encumbered, non-equity space comparable in size, quality and location to the
Premises for a comparable term, which comparable space is located in the
Building and in office buildings of comparable size, location, amenities,
services and quality of construction in the Newport Center area of Newport
Beach, California area, taking into consideration all monetary concessions being
granted in connection with such comparable space, including, without limitation,
the following concessions (collectively, the "Rent Consessions"): (a) rental
abatement concessions, if any, being granted in connection with such comparable
space, (b) tenant improvements or allowances being given in connection with such
comparable space, provided that such rent shall take into account, and deduct
the value of, the existing improvements in the Premises, with such value to be
based upon the age, quality and layout of the improvements and the extent to
which they can be utilized by Tenant and acknowledging that the precise tenant
improvements in the Premises are specifically suitable to Tenant, (c) all other
monetary concessions, if any, being granted such tenants in connection with such
comparable space, including without limitation any lease buy-outs, and (d) with
respect to any First Offer Space, Landlord's payment of broker's fees and
commissions (if any), moving allowances, buy-outs of prior leases, Landlord's
payment or reimbursement of termination fees for prior leases, the value of
extraordinary services, free or reduced-rate parking privileges, reduced rent or
free rent, options to extend at fixed or below market rates, and all other
concessions having economic value granted to tenants; provided, however, that in
calculating the Fair Market Rental Value with respect to space other than First
Offer Space, no consideration shall be given to (x) any rental abatement granted
such tenants in connection with the construction of improvements in the
comparable space, or (y) the fact that Landlord is not required to pay a real
estate brokerage commission in connection with such transaction and landlords
are or are not paying a commission in connection with such comparable
transactions.

          2.2.1   If in determining the Fair Market Rental Value, Rent
Concessions are granted as provided above, Landlord may, at Landlord's sole
option, elect any or a portion of the following:  (A) to grant the Rent
Concessions to Tenant in the form as described above (e.g., as free rent and/or
an improvement allowance), and/or (B) to grant Tenant the present value of any
or all of the Rent Concessions in the form of free rent or reduced "face" or
"stated" rental, which reduction in rental shall be calculated on a dollar-for-
dollar basis over a period and in installments as determined by Landlord (in
which case the Rent Concession(s) converted into free rent or rental deduction
shall not be granted to Tenant).

          2.2.2   Tenant shall have the right, but not the obligation, to
deliver written notice to Landlord after January 1, 2004 but in any event no
                                                                          --

option to extend the Lease Term ("Tenant's Notice of Interest").  In the event
that Tenant shall timely deliver to Landlord Tenant's Notice of Interest,
Landlord, within the later to occur of sixty (60) days after Landlord's receipt
of Tenant's notice of Interest or May 31, 2004, shall deliver to Tenant a notice
("Option Rent Notice"), setting forth the Landlord's determination of the Option
Rent.  In no event shall Tenant's delivery of Tenant's Notice of Interest be a
condition precedent to Tenant's

                                       6
<PAGE>
 
exercise of the extension option, but shall instead only be a condition
precedent to Landlord's obligation to deliver the Option Rent Notice. Regardless
of whether Tenant delivers Tenant's Notice of Interest, Tenant shall exercise
the extension option only by delivery to Landlord of written notice of such
exercise on or before June 30, 2004, but not before April 1, 2004.

          2.2.3   Upon Tenant's exercise of Tenant's extension right hereunder
or expansion right with respect to any First Offer Space, Landlord and Tenant
shall attempt to agree upon the Fair Market Rental Value using their good-faith
efforts. If Landlord and Tenant fail to reach agreement within thirty (30) days
following Tenant's exercise of such right (the "Outside Agreement Date"), then
each party shall make a separate determination of the Fair Market Rental Value
within five (5) days after the Outside Agreement Date, and such determinations
shall be submitted to arbitration in accordance with Section 2.2.3.1 through
                                                     ---------------

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

                  2.2.3.1  Landlord and Tenant shall each appoint one arbitrator
who shall by profession be a certified real estate appraiser who shall have been
active over the five (5) year period ending on the date of such appointment in
the appraisal of first-class commercial high-rise properties in the Newport
Center area of Newport Beach, California.  The determination of the arbitrators
shall be limited solely to the issue as to whether Landlord's or Tenant's
submitted Fair Market Rental Value is the closest to the actual Fair Market
Rental Value as determined by the arbitrators, taking into account the
requirements of Section 2.2 above.  Each such arbitrator shall be appointed
                -----------                                                
within fifteen (15) days after the applicable Outside Agreement Date.

                  2.2.3.2  The two arbitrators so appointed shall within ten
(10) days of the date of the appointment of the last appointed arbitrator agree
upon and appoint a third arbitrator who shall be qualified under the same
criteria set forth hereinabove for qualification of the initial two arbitrators.

                  2.2.3.3  The three arbitrators shall within thirty (30) days
of the appointment of the third arbitrator reach a decision as to whether the
parties shall use Landlord's or Tenant's submitted Fair Market Rental Value, and
shall notify Landlord and Tenant thereof.

                  2.2.3.4  The decision of the majority of the three arbitrators
shall be binding upon Landlord and Tenant.

                  2.2.3.5  If either Landlord or Tenant fails to appoint an
arbitrator within fifteen (15) days after the applicable Outside Agreement Date,
the arbitrator appointed by one of them shall reach a decision, notify Landlord
and Tenant thereof, and such arbitrator's decision shall be binding upon
Landlord and Tenant.

                  2.2.3.6  If the two arbitrators fail to agree upon and appoint
a third arbitrator, or both parties fail to appoint an arbitrator, then the
appointment of the third arbitrator or any arbitrator shall be dismissed and the
matter to be decided shall be forthwith submitted to arbitration under the
provisions of the American Arbitration Association, but subject to the
instruction set forth in this Section 2.2.3.
                              ------------- 

                  2.2.3.7  Landlord shall be responsible for the cost of the
arbitrator appointed by Landlord, Tenant shall be responsible for the cost of
the arbitrator appointed by Tenant, and Landlord and Tenant shall equally share
the cost of the third arbitrator and all other costs of the arbitration
proceeding.

Landlord under that certain Office Lease dated July 19, 1995 (the "Advisors
Lease"), and the term of the Advisors Lease expires on May 31, 2002. By
execution of this Lease by Landlord and Tenant, Tenant acknowledges and agrees

acknowledges that Landlord is not obligated to make any leasehold improvements
to the Premises under this Lease and that Tenant is accepting possession of the
Premises under the OAS ISO condition of the Premises, subject to Landlord's
payment to Tenant of the Tenant Improvement Allowance pursuant to Section 2.1

     Tenant shall pay, without notice or demand, to Landlord at a lockbox
designated by Landlord, or at such other place as Landlord may from time to time
designate in writing, in the form of a check (which is drawn upon a bank which

payment, is legal tender for private or public debts in the United States  of
America, base rent ("Base Rent") as set forth in Section 8 of the Summary

the Lease Commencement Date) falls on a day of a calendar month other than the
first day of such calendar month or if any Rent payment is for a period which is
shorter than one calendar month, the Rent for any fractional calendar month
shall accrue on a daily basis for the period from the date such payment is due
to the end of such calendar month or to the end of the Lease Term at a rate per
day which is equal to 1/365 of the Rent.  All other payments or adjustments
required to be made under the terms of this Lease that require proration on a
time basis shall be prorated on the same basis.

Space then leased hereunder), or (ii) the applicable Must-Take Space
Commencement Date with respect to other Must-Take Space, Tenant shall pay as
additional rent "Tenant's Share" of the annual "Project Expenses," as those

                     ------------------------                                
the extent such Project Expenses are in excess of Tenant's share of Project
Expenses applicable to the "Base Year," as that term is defined in Section 4.2.1
                                                                   -------------
of this Lease.  Such additional rent, together with any and all other amounts
payable by Tenant to Landlord, as additional rent or otherwise, pursuant to the

Rent shall be payable for the same periods and in the same manner, time and
place as the Base Rent.  Without limitation on other obligations of Tenant which
shall survive the expiration of the Lease Term, the obligations of Tenant to pay

     4.2  Definitions.  As used in this Article 4, the following terms shall
          -----------                   ---------                           
have the meanings hereinafter set forth:

          4.2.1   "Base Year" shall mean the period set forth in Section 9.1 of

portion of the Lease Term falls, through and including the calendar year in
which the Lease Term expires.

          4.2.3   "Operating Expenses" shall mean all expenses, costs and
amounts of every kind and nature which Landlord shall pay or incur during any
Expense Year because of or in connection with the ownership, management,
maintenance, repair, replacement, restoration or operation of the Project,
including, without limitation, any amounts paid or incurred for (i) the cost of
supplying all utilities, the cost of operating, maintaining, repairing,
replacing, renovating and managing the utility systems, mechanical systems,
sanitary and storm drainage systems, and escalator and elevator systems, and the
cost of supplies, tools, and equipment and maintenance and service contracts in
connection therewith; (ii) the cost of licenses, certificates, permits and
inspections and the cost of contesting the validity or applicability of any
governmental enactments which may affect Operating Expenses, and the costs
incurred in connection with the implementation and operation of a transportation
system management program or similar program; (iii) the cost of insurance
carried by Landlord in connection with the Project, in such amounts as Landlord
may reasonably determine; (iv) the cost of landscaping, relamping, and all
supplies, tools, equipment and  materials used in the operation, repair and
maintenance of the Project; (v) the cost of parking area repair and maintenance,
including, but not limited to, resurfacing, repainting, restriping, and
cleaning; (vi) fees, charges and other costs, including management fees (or

all persons engaged by Landlord or otherwise reasonably incurred by Landlord in
connection with the management, operation, maintenance and repair of the
Project; (vii) any equipment rental agreements or management agreements
(including the cost of any management fee and the fair rental value of any
office space provided thereunder); (viii) wages, salaries and other compensation
and benefits of all persons engaged in the operation, maintenance or security of
the Project, and employer's Social Security taxes, unemployment taxes or
insurance, and any other taxes which may be levied on such wages, salaries,
compensation and benefits; provided, that if any employees of Landlord provide
services for more than one building of Landlord, then a prorated portion of such
employees' wages, benefits and taxes shall be included in Operating Expenses
based on the portion of their working time devoted to the Project; (ix)

                                       9
<PAGE>
 
payments under any easement, license, operating agreement, declaration,
restrictive covenant, or instrument pertaining to the sharing of costs by the
Project; (x) amortization (including interest on the unamortized cost at a rate
equal to the floating commercial loan rate announced from time to time by Bank
of America, a national banking association, as its prime rate, plus 2% per annum
[the "Interest Rate"]) of the cost of acquiring or the rental expense of
personal property used in the maintenance, operation and repair of the Project;
and (xi) the cost of capital improvements incurred in connection with the
Project (A) which relate to the operation, repair, maintenance and replacement
of all systems, equipment or facilities which serve the Project in the whole or
in part, (B) which are intended as a labor-saving device or to effect other
economies in the operation or maintenance of the Project, or any portion
thereof, or (C) that are required under any governmental law or regulation;
provided however, Operating Expenses shall not include such costs for compliance
with the Americans with Disabilities Act of 1990 (the "ADA"), except to the
extent of modifications or amendments to the ADA or regulations promulgated
thereunder hereinafter enacted or adopted, as the case may be, and further
provided that Operating Expenses shall not include costs of compliance with the
ADA to the extent such costs are incurred by the specific unconventional, unique
or exceptional use of another tenant of the Building; provided further, however,
that each such permitted capital expenditure shall be amortized (including
interest on the unamortized cost) over its useful life as determined in
accordance with generally accepted accounting principles consistently applied.
If the Project is not fully occupied during all or a portion of any Expense
Year, Landlord shall make an appropriate adjustment to the variable components
of Operating Expenses for such Expense Year as reasonably determined by Landlord
employing sound real estate management principles, to determine the amount of
Operating Expenses that would have been paid had the Project been ninety-five
percent (95%) occupied, and the amount so determined shall be deemed to have
been the amount of Operating Expenses for such Expense Year. Notwithstanding the
foregoing, for purposes of this Lease, Operating Expenses shall not, however,
include (A) except as otherwise set forth above in this Section 4.2,
                                                        -----------

deductible amount under any insurance policy shall be included within Operating
Expenses) or from a third party. Except as specifically permitted within the
definition of "Operating Expenses" set forth above, Operating Expenses shall
also exclude the following: (i) any ground lease rental; (ii) costs incurred by
     -------
Landlord with respect to goods and services (including utilities sold and
supplied to tenants and occupants of the Building) to the extent that Landlord
is entitled to reimbursement for such costs other than through the operating

Landlord for repairs, replacements and/or restoration to or of the Building or
the common areas thereof to the extent that Landlord is reimbursed by insurance
or condemnation proceeds or by tenants, warrantors or other third persons (other
than through operating cost pass throughs); (iv) costs, including costs of
plans, construction, permit, license and inspection costs, incurred with respect
to the installation of tenant improvements made for other tenants in the
Building or incurred in renovating or otherwise improving, decorating, painting

attorneys' fees and other costs and expenses incurred in connection with
negotiations or disputes with present or prospective tenants or other occupants

        -----------
capital improvements, capital replacements, capital repairs, capital equipment

financing or the maximum rate allowed by law on the unamortized balance) of the
following capital improvements, repairs, replacements, equipment and tools shall
be included in the definition of operating costs: (a) capital improvements,
repairs, replacements, equipment and tools made to comply with any law or

                                       10

governmental regulation, where such governmental requirement did not apply prior
to April 1, 1998; (b) capital improvements, repairs, replacements, equipment and
tools which reduce operating costs, where the cost of such capital improvement,
repair, replacement, equipment or tools is less than the amount of operating
costs reasonably anticipated to be saved over the anticipated useful life of the
item; and (c) any other capital improvements, repairs, replacements, equipment
and tools not to exceed Ten Thousand Dollars ($10,000.00) in any calendar year;
(vii) brokerage commissions, tenant incentives, finders' fees, attorney's fees,
advertising expenses, entertainment and travel expenses and other costs incurred
by Landlord in leasing or attempting to lease space in the Building; (viii)
interest on debt or amortization on any mortgage or mortgages encumbering the
Building or the common areas thereof; (ix) Landlord's general corporate
overhead; (x) subject to the same three (3) exceptions set forth in clause
"(vi)" above, rental payments incurred in leasing air conditioning systems,

negligence or willful misconduct of Landlord, Landlord's employees, contractors
or agents and to the extent Landlord can identify such persons and collect the
costs of any such damages or repair therefrom (with Landlord using Landlord's
commercially reasonable efforts to do so), other tenants and their employees,
contractors or agents; (xxi) executive salaries or salaries of service personnel
(including the Building superintendent) to the extent that such service-
personnel perform services other than in connection with the management,

accountants' fees and other expenses associated with the enforcement of any
leases or defense of Landlord's title to or interest in the Building or any part
thereof; (xxiii) costs incurred with respect to the repair and maintenance of
the Common Area due to (1) violation by Landlord of the terms and conditions of
any provision of the Lease or any other lease in the Building; (2) violation by

furnished to some tenants which are not furnished to Tenant or quantities of
such services furnished to some tenants which are also furnished to Tenant but
are furnished to other tenants in an amount materially in excess of that which
would represent a fair proportion of such services; (xxv) compensation and
related costs of Landlord's employees above the level of Project manager; (xxvi)
that portion of the costs of goods or services supplied to the Project by
Landlord or an affiliate of Landlord in excess of the cost of such goods or
services if supplied by other vendors in the Newport Center area of Newport
Beach, California; (xxvii) the cost of abating any Hazardous Materials at or on
the Project as of the Lease Commencement Date or thereafter on the Project
except to the extent Landlord is unable, after using Landlord's commercially
reasonable efforts to do so, to identify the person(s) or entity(ies)
responsible for any such Hazardous Materials being on the Project and to collect
the cost of removal therefrom; and (xxviii) any amount or fee allocated as a
management fee for the Project in excess of the actual management fee paid by
Landlord for the management of the

                                       11
<PAGE>
 
Project. In no event shall any portion of any expense be included as an
Operating Expense if recovered from Tenant or any other tenant of the Project
under any provision of such tenant's lease other than that pertaining to
recovery of Operating Expenses. Landlord shall not collect in excess of one
hundred percent (100%) of all Operating Expenses from the tenants of the
Building. If Landlord does not carry earthquake or any other insurance during
the Base Year (calendar year 1998) but carries earthquake or such other
insurance during any subsequent calendar year, then for purposes of calculating
Operating Expenses payable by Tenant during such subsequent calendar year,
Operating Expenses for the Base Year shall be deemed to be increased by the
amount which Landlord would have incurred had Landlord carried such insurance
during such Base Year.

          4.2.4   "Project Expenses" shall mean "Operating Expenses" and "Tax
Expenses."

          4.2.5   "Tax Expenses" shall mean all federal, state, county, or local
governmental or municipal taxes, fees, charges or other impositions of every
kind and nature, whether general,  special, ordinary or extraordinary
(including, without limitation, real estate taxes, general and special
assessments, transit taxes, leasehold taxes or taxes based upon the receipt of
rent, including gross receipts or sales taxes applicable to the receipt of rent,
unless required to be paid by Tenant, personal property taxes imposed upon the
fixtures, machinery, equipment, apparatus, systems and equipment, appurtenances,
furniture and other personal property used in connection with the Project),
which Landlord shall pay or incur during any Expense Year (without regard to any
different fiscal year used by such governmental or municipal authority) because
of or in connection with the ownership, leasing and operation of the Project.
For purposes of this Lease, Tax Expenses shall be calculated as if the tenant
improvements in the Project were fully constructed and the Project, and all
tenant improvements in the Project were fully assessed for real estate tax
purposes, and accordingly, during the portion of any Expense Year occurring
during the Base Year, Tax Expenses shall be deemed to be increased
appropriately.  Tax Expenses which are levied on a fiscal year basis shall be
deemed to apply one-twelfth (1/12th) to each calendar month in such fiscal year.

                  4.2.5.1  Tax Expenses shall include, without limitation:

                           (i) Any assessment, tax, fee, levy or charge in
addition to, or in substitution, partially or totally, of any assessment, tax,
fee, levy or charge previously included within the definition of real property
tax, it being acknowledged by Tenant and Landlord that Proposition 13 was
adopted by the voters of the State of California in the June 1978 election
("Proposition 13") and that assessments, taxes, fees, levies and charges may be
imposed by governmental agencies for such services as fire protection, street,
sidewalk and road maintenance, conservation, refuse removal and for other
governmental services formerly provided without charge to property owners or
occupants, and, in further recognition of the decrease in the level and quality
of governmental services and amenities as a result of Proposition 13, Taxes
shall also include any governmental or private assessments or the Project's
contribution towards a governmental or private cost-sharing agreement for the
purpose of augmenting or improving the quality of services and amenities
normally provided by governmental agencies. It is the intention of Tenant and
Landlord that all such new and increased assessments, taxes, fees, levies, and
charges and all similar assessments, taxes, fees, levies and charges be included
within the definition of Tax Expenses for purposes of this Lease;

                           (ii) Any assessment, tax, fee, levy, or charge
allocable to or measured by the area of the Premises or the Rent payable
hereunder, including, without limitation, any gross income tax with respect to
the receipt of such rent, or upon or with respect to the possession, leasing,
operating, management, maintenance, alteration, repair, use or occupancy by
Tenant of the Premises, or any portion thereof;

                                       12
<PAGE>
 
                          (iii)  Any assessment, tax, fee, levy or charge, upon
this transaction or any document to which Tenant is a party, creating or
transferring an interest or an estate in the Premises; and

                          (iv)   Any possessory taxes charged or levied in lieu
of real estate taxes.

                 4.2.5.2  Any reasonable expenses incurred by Landlord in
attempting to protest, reduce or minimize Tax Expenses shall be included in Tax
Expenses in the Expense Year such expenses are paid.  Tax refunds shall be
deducted from Tax Expenses in the Expense Year they are received by Landlord.
The amount of Tax Expenses for the Base Year attributable to the valuation of
the Real Property, inclusive of tenant improvements, shall be known as "Base
Taxes."  If, in any comparison year subsequent to the Base Year, the amount of
Base Taxes decreases, then for purposes  of all subsequent comparison years,
including the comparison year in which such decrease in Tax Expenses occurred,
the Base Year shall be decreased by an amount equal to the decrease in Tax
Expenses.

                 4.2.5.3  Notwithstanding anything to the contrary contained in
this Section 4.2.5 (except as set forth in Section 4.2.5.1 and levied in whole
     -------------                         ---------------                    
or part in lieu of Tax Expenses), there shall be excluded from Tax Expenses (i)
all excess profits taxes, franchise taxes, gift taxes, capital stock taxes,
inheritance and succession taxes, estate taxes, federal and state income taxes,
and other taxes to the extent applicable to Landlord's general or net income (as
opposed to rents, receipts or income attributable to operations at the Project),
(ii) any items included as Operating Expenses, and (iii) any items paid by
Tenant under Section 4.6 of this Lease.
             -----------               

          4.2.6  "Tenant's Share" shall mean the percentage set forth in
                                                                         
Section 9.2 of the Summary.  Tenant's Share was calculated by multiplying the
- -----------                                                                  
number of rentable square feet of the Premises by 100 and dividing the product
by the total rentable square feet in the Project.  In the event either the
Premises and/or the Project is expanded or reduced, Tenant's Share shall be
appropriately adjusted, and, as to the Expense Year in which such change occurs,
Tenant's Share for such year shall be determined on the basis of the number of
days during such Expense Year that each such Tenant's Share was in effect.

     4.3  Allocation of Project Expenses to Tenants of the Project.  Landlord
          --------------------------------------------------------           
shall have the right, from time to time, to equitably allocate some or all of
the Operating Costs and Taxes for the Project among different portions or
occupants of the Project (the "Cost Pools"), in Landlord's reasonable
discretion.  Such Cost Pools may include, but shall not be limited to, the
office space tenants of a building of the Project or of the Project, and the
retail space tenants of a building of the Project or of the Project.  The
Operating Costs and Taxes within each such Cost Pool shall be allocated and
charged to the tenants within such Cost Pool in the manner provided in Section
4.2.6.

     4.4  Calculation and Payment of Additional Rent.
          ------------------------------------------ 

          4.4.1   Calculation of Excess.  Subject to the first sentence of
                  ---------------------                                   
Section 4.1, if for any Expense Year ending or commencing within the Lease Term,
Tenant's Share of Project Expenses for such Expense Year exceeds Tenant's Share
of the amount of Project Expenses applicable to the Base Year, then Tenant shall
pay to Landlord, in the manner set forth in Section 4.4.2, below, and as
                                            -------------               
Additional Rent, an amount equal to the excess (the "Excess").  Any Excess for a
partial Expense Year during the Lease Term shall be prorated at a per diem rate
based on the actual number of days of the Lease Term occurring within such
Expense Year.

          4.4.2   Statement of Actual Project Expenses and Payment by Tenant.
                  ----------------------------------------------------------  
Landlord shall deliver to Tenant, on or before the first day of May following
the end of each Expense Year or as

                                       13
<PAGE>
 
soon thereafter as reasonably practicable, a statement (the "Statement") which
shall state the Project Expenses incurred or accrued for such preceding Expense
Year and the amount thereof allocated to the tenants of the Building, and which
shall indicate the amount, if any, of any Excess. Upon receipt of the Statement
for each Expense Year ending during the Lease Term, if an Excess is present,
Tenant shall pay, with its next installment of Base Rent due, the full amount of
the Excess for such Expense Year, less the amounts, if any, paid during such
Expense Year as "Estimated Excess," as that term is defined in Section 4.4.4
                                                               -------------
below. The failure of Landlord to timely furnish the Statement for any Expense
Year shall not prejudice Landlord from enforcing its rights under this Article
4; provided however, that Tenant shall not be responsible for any Excess not
billed to Tenant within two (2) years after the end of the applicable Expense
Year. Even though the Lease Term has expired and Tenant has vacated the
Premises, when the final determination is made of Tenant's Share of the Project
Expenses allocated to the tenants of the Building for the Expense Year in which
this Lease terminates, if an Excess is present, Tenant shall immediately pay to
Landlord an amount as calculated pursuant to the provisions of Section 4.4.1 of
                                                               -------------
this Lease. The provisions of this Section 4.4.2 shall survive the
                                   -------------
expiration or earlier termination of the Lease Term.

          4.4.3   Statement of Estimated Project Expenses.  In addition,
                  ---------------------------------------               
Landlord shall give Tenant a yearly expense estimate statement (the "Estimate
Statement") which shall set forth Landlord's reasonable estimate (the
"Estimate") of what the total amount of Project Expenses for the then-current
Expense Year  shall be and the estimated Excess (the "Estimated Excess") as
calculated by comparing Tenant's share of Project Expenses allocated to the
tenants of the Building, which shall be based upon the Estimate, to Tenant's
share of Project Expenses applicable to the Base Year, which Estimate Statement
may be revised and reissued by Landlord not more frequently than once during any
Expense Year.  The failure of Landlord to timely furnish the Estimate Statement
for any Expense Year shall not preclude Landlord from enforcing its rights to
collect any Estimated Excess under this Article 4.  If pursuant to the Estimate
                                        ---------

then-current Expense Year, Tenant shall pay, with its next installment of Base
Rent due, a fraction of the Estimated Excess (or the increase in the Estimated
Excess if pursuant to a revised Estimated Statement) for the then-current
Expense Year (reduced by any amounts paid pursuant to the last sentence of this

which have elapsed in such current Expense Year to the month of such payment,
both months inclusive, and shall have twelve (12) as its denominator.  Until a
new Estimate Statement is furnished, Tenant shall pay monthly, with the monthly
Base Rent installments, an amount equal to one-twelfth (1/12) of the total
Estimated Excess set forth in the previous Estimate Statement delivered by
Landlord to Tenant.

     4.5  Allocation of Project Expenses.  Notwithstanding anything to the
          ------------------------------                                  
contrary set forth in this Article 4, when calculating the Project Expenses for
                           ---------                                           
the Base Year, such Project Expenses shall not include any increase in Tax
Expenses attributable to special assessments, charges, costs, or fees, or due to
modifications or changes in governmental laws or regulations, including but not
limited to the institution of a split tax roll, and Operating Expenses shall
exclude market-wide labor-rate increases due to extraordinary circumstances,
including, but not limited to, boycotts and strikes, and utility rate increases
due to extraordinary circumstances including, but not limited to, conservation
surcharges, boycotts, embargoes or other shortages and amortized costs relating
to capital improvements.

     4.6  Taxes and Other Charges for Which Tenant Is Directly Responsible.
          ----------------------------------------------------------------  
Tenant shall reimburse Landlord, as Additional Rent, within thirty (30) days
after Tenant's receipt of Landlord's invoice therefor for any and all taxes
required to be paid by Landlord (except to the extent included in Tax Expenses
by Landlord), excluding state, local and federal personal or corporate income
taxes measured by the net income of Landlord from all sources and estate and
inheritance taxes, whether or not now customary or within the contemplation of
the parties hereto, when:

                                       14
<PAGE>
 
          4.6.1   Said taxes are measured by or reasonably attributable to the
cost or value of Tenant's equipment, furniture, fixtures and other personal
property located in the Premises;

          4.6.2   Said taxes are assessed upon or with respect to the
possession, leasing, operation, management, maintenance, alteration, repair, use
or occupancy by Tenant of the Premises, any portion of the Project or the
parking facility used by Tenant in connection with this Lease; or

          4.6.3   Said taxes are assessed upon this transaction or any document
to which Tenant is a party creating or transferring an interest or an estate in
the Premises.

     4.7  Landlord's Books and Records.  Within one hundred twenty (120) days
          ----------------------------                                       
after receipt of a Statement by Tenant, if Tenant disputes the amount of
Additional Rent set forth in the Statement, Tenant shall have the right to have
an audit conducted of Landlord's books and records relating to Project Expenses
by an independent certified public accountant (which accountant is a member of
a nationally or regionally recognized accounting firm), or consultant with at
least five (5) years experience examining Project Expenses working on a non-
contingent fee basis, in each case mutually agreed upon by Landlord and Tenant;
provided however, Tenant shall pay any such disputed amount pending completion
of such audit.  Notwithstanding anything to the contrary set forth herein, the
audit with respect to Project Expenses for the first three (3) Expense Years
during the Lease Term may be deferred until the date one hundred twenty (120)
days after Tenant receives the Statement for the third Expense Year occurring
during the Lease Term.  The amounts payable under this Lease by Landlord to
Tenant or Tenant to Landlord, as the case may be, shall be appropriately
adjusted on the basis of such audit.  If such audit discloses a liability for
further refund by Landlord to Tenant in excess of five percent (5%) of the
Operating Expenses previously made by Tenant for such calendar year, the cost of
such audit shall be borne by Landlord; otherwise the cost of such audit shall be
borne by Tenant.  If Tenant shall not request an audit in accordance with the
provisions of this Section 4.7 within the time permitted herein, such Statement
                   -----------                                                 
shall be conclusively binding upon Landlord and Tenant.

     4.8  Ownership of Building.  Anything contained in the Lease to the
          ---------------------                                         
contrary notwithstanding, Tenant acknowledges and agrees that for so long as the
Building is owned by the state or any local public entity or government,
including without limitation a state public retirement system, the Lease and
Tenant's interest hereunder may constitute a possessory interest subject to
property taxation and as a result Tenant may be subject to the payment of
property taxes levied on that interest.  In addition, for so long as the
Building is owned by a state public retirement system, the full cash value, as
defined in Sections 110 and 110.1 of the California Revenue and Taxation Code,
of the possessory interest upon which property taxes will be based will equal
the greater of (A) the full cash value of the possessory interest, or (B) if
Tenant has leased less than all of  the building, Tenant's Share of the full
cash value of the Building that would have been enrolled if the Building had
been subject to property tax upon acquisition by the state public retirement
system.  Tenant's Share will be the number of rentable square feet of Tenant's
Premises divided by the total number of rentable square feet of the Building.

gas, water, or other fuel at the Building or Project after reasonable effort to
do so, by any accident or casualty whatsoever, by act or default of Tenant or
other parties, or by any other cause beyond Landlord's reasonable control.
Notwithstanding the foregoing, Landlord agrees to use Landlord's commercially
reasonable efforts to minimize any such service disruption as soon as is
reasonably practicable except to the extent caused by Tenant or Tenant's agents,
employees, contractors or invitees.  To the extent any such failure, delay or
diminution is caused by Landlord or Landlord's agents, employees or contractors
and such disruption continues in excess of one (1) business day, then there
shall thereafter be an equitable abatement of rent so long as such disruption
continues.  Furthermore, Landlord shall not be liable under any circumstances
for a loss of, or

including, without limitation, loss of profits, however occurring, through or in
connection with or incidental to a failure to furnish any of the services or
utilities as set forth in this Article 6. Landlord may comply with voluntary

controls or guidelines promulgated by any governmental entity relating to the
use or conservation of energy, water, gas, light or electricity or the reduction
of automobile or other emissions without creating any liability of Landlord to
Tenant under this Lease, provided that the Premises are not thereby rendered
untenantable.

repair all damaged or broken fixtures and appurtenances; provided however, if
Tenant fails to make such repairs within ten (10) days after Landlord's demand
therefor (or such lesser period of time as may be appropriate in the event of an
emergency), Landlord may, but need not, make such repairs and replacements, and
Tenant shall pay Landlord the cost thereof, including three percent (3%) of the
cost thereof to reimburse Landlord for overhead, general conditions, fees and
other costs or expenses arising from Landlord's involvement with such repairs
and replacements forthwith upon being billed for same.  Landlord may, but shall
not be required to, enter the Premises at all reasonable times to make such
repairs, alterations, improvements and additions to the Premises or to the
Project or to any equipment located in the Project as Landlord shall desire or
deem necessary or as Landlord may be required to do by governmental or quasi-
governmental authority or court order or decree; provided however, Landlord
agrees to use Landlord's commercially reasonable efforts to do the foregoing in
a manner which minimizes interference with Tenant's business and with reasonable
prior notice to Tenant (which may be telephonic notice to Tenant's facilities
manager) and to schedule disruptive work after Tenant's business hours or at
other times scheduled in cooperation with Tenant.  Landlord agrees to maintain
the base, shell and core of the Building in good condition and repair consistent
with a first class office building.  If Landlord fails to do so, Tenant may
exercise Tenant's rights pursuant to Section 19.6 hereof.  Except as expressly

provided in this Lease, Tenant hereby waives and releases its right to make
repairs at Landlord's expense under Sections 1941 and 1942 of the California
Civil Code or under any similar law, statute, or ordinance now or hereafter in
effect.

thirty (30) days prior to the commencement thereof, and which consent shall not
be unreasonably withheld, delayed or conditioned by Landlord; provided that
Landlord shall not be required to consent to any Alterations which cause
Hazardous Material to be incorporated into or brought into the Project or
Premises.  Landlord's consent shall not be required in connection with Tenant's
recarpeting or repainting the interior of the Premises or relocation of modular
furniture and modular offices; however, Tenant shall give Landlord at least ten
(10) days' prior written notice of any 

                                       19

such repainting or recarpeting. The construction of the initial improvements to
the Premises shall be governed by the terms of the Tenant Work Letter, attached
hereto as Exhibit D, and not the terms of this Article 8.
          ---------                            ---------

     8.2  Manner of Construction.  Landlord may impose, as a condition of its
          ----------------------                                             
consent to all Alterations or repairs of the Premises or about the Premises
which require Landlord's approval, such reasonable requirements as Landlord in
its reasonable discretion may deem desirable, including, but not limited to, the
requirement that upon Landlord's request, Tenant shall, at Tenant's expense,
remove upon the expiration or any early termination of the Lease Term such
Alterations as are in Landlord's reasonable opinion not likely to be used by
subsequent tenants, such as, but not limited to, theatre space or exceptionally
large or unusually shaped seminar or conference rooms, and/or the requirement
that Tenant utilize for such purposes only contractors, materials, mechanics and
materialmen reasonably approved by Landlord.  Upon request of Tenant made at the
time Tenant requests Landlord's approval of such Alterations, Landlord will
notify Tenant whether Landlord will require removal of such Alterations upon the
expiration or any early termination of the Lease Term.  Tenant shall construct
such Alterations and perform such repairs in conformance with any and all
applicable rules and regulations of any federal, state, county or municipal code
or ordinance and pursuant to a valid building permit, issued by the City of
Newport Beach, in conformance with Landlord's reasonable construction rules and
regulations, a copy of which construction rules and regulations in effect as of
the date hereof have been delivered to Tenant.  All work with respect to any
Alterations must be done in a good and workmanlike manner and diligently
prosecuted to completion to the end that the Premises shall at all times be a
complete unit except during the period of work.  In performing the work of any
such Alterations, Tenant shall have the work performed in such manner as not to
obstruct access to the Project, Building or Common Areas or any portion thereof,
by any other tenant of the Project, and as not to obstruct the business of
Landlord, other tenants in the Project, or interfere with the labor force
working in the Project.  Upon completion of any Alterations, Tenant agrees to
notify Landlord so Landlord can cause a timely Notice of Completion to be
recorded in the office of the Recorder of the County of Orange in accordance
with the terms of Section 3093 of the Civil Code of the State of California or
any successor statute, and Tenant shall deliver to the Building management
office a reproducible copy of the "as built" drawings of the Alterations, or if
Tenant has not obtained such "as built" drawings and subject to Landlord's right
to require "as built" drawings, a reproducible copy of the construction drawings
of the Alterations.

     8.3  Payment for Improvements.  Upon completion of such work, Tenant shall
          ------------------------                                             
deliver to Landlord evidence of payment, contractors' affidavits and full and
final waivers of  all liens for labor, services or materials.  Tenant shall pay
to Landlord three percent (3%) of the cost of such work to compensate Landlord
for all overhead, general conditions, fees and other costs and expenses arising
from Landlord's involvement with such work.

     8.4  Construction Insurance.  In the event that Tenant makes any
          ----------------------                                     
Alterations, Tenant agrees to carry "Builder's All Risk" insurance in an amount
equal to the cost of the Alterations covering the construction of such
Alterations, it being understood and agreed that all of such Alterations shall
be insured by Tenant pursuant to Article 10 of this Lease immediately upon
                                 ----------                               
completion thereof.  In addition, Landlord may, in its discretion, require
Tenant to obtain a lien and completion bond or some alternate form of security
satisfactory to Landlord in an amount sufficient to ensure the lien-free
completion of such Alterations and naming Landlord as a co-obligee.  Landlord
agrees not to require any such bond or security so long as the Tenant is the
original Tenant executing this Lease or an assignee permitted under Section 14.7
                                                                    ------------
hereof without Landlord's consent, and such Tenant occupies the portion of the
Premises subject to the Alterations.

     8.5  Landlord's Property.  All Alterations, improvements, fixtures and/or
          -------------------

signs installed in, on or about the Premises, from time to time, shall be at the
sole cost of Tenant and shall be and become the property of Landlord at

improvements, fixtures and/or equipment which Tenant can substantiate to
Landlord have not been paid for with any tenant improvement allowance funds
provided to Tenant by Landlord, provided Tenant repairs any damage to the
Premises and Building caused by such removal. Furthermore, if Landlord, as a
condition to Landlord's consent to any Alteration, requires pursuant to the
standard and in the manner provided in Section 8.2 that Tenant remove any
                                       -----------
Alteration upon the expiration or early termination of the Lease Term, Landlord
may, by written notice to Tenant prior to the end of the Lease Term, or given
upon any earlier termination of this Lease, require Tenant at Tenant's expense
to remove such Alterations and to repair any damage to the Premises and Building
caused by such removal. If Tenant fails to complete such removal and/or to
repair any damage caused by the removal of any Alterations, Landlord may do so
and may charge the cost thereof to Tenant.

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

     Tenant has no authority or power to cause or permit any lien or encumbrance
of any kind whatsoever, whether created by act of Tenant, operation of law or
otherwise, to attach to or be placed upon the Project, Building or Premises, and
any and all liens and encumbrances created by Tenant shall attach to Tenant's
interest only.  Landlord shall have the right at all times to post and keep
posted on the Premises any notice which it deems necessary for protection from
such liens.  Tenant covenants and agrees not to suffer or permit any lien of
mechanics or materialmen or others to be placed against the Project, the
Building or the Premises with respect to work or services claimed to have been
performed for or materials claimed to have been furnished to Tenant or the
Premises, and, in case of any such lien attaching or notice of any lien
resulting from work or materials ordered by Tenant, Tenant covenants and agrees
to cause it to be promptly released and removed of record by payment or by
posting a proper statutory lien release bond.  Notwithstanding anything to the
contrary set forth in this Lease, in the event that such lien is not released
and removed on or before the date occurring thirty (30) days after notice of
such lien is delivered by Landlord to Tenant, Landlord, at its sole option, may
immediately take all action necessary to release and remove such lien, without
any duty to investigate the validity thereof, and all sums, costs and expenses,
including reasonable attorneys' fees and costs, incurred by Landlord in
connection with such lien shall be deemed Additional Rent under this Lease and
shall be due and payable by Tenant within thirty (30) days after Tenant's
receipt of Landlord's invoice therefor.

Landlord, its partners, trustees, ancillary trustees and their respective
officers, directors, shareholders, beneficiaries, agents, servants, employees,
and independent  contractors (collectively, the "Landlord Parties") shall not be
liable for any damage either to person or property or resulting from the loss of
use thereof, which damage is sustained by Tenant or by other persons claiming
through Tenant and which is not the result of the negligence or intentional act
of Landlord, its agents, employees and contractors.  Tenant shall indemnify,

reasonable attorneys' fees) incurred in connection with or arising from any
cause in, on or about the Premises, either prior to, during, or after the

any claims or liability occurring prior to such expiration or termination.

     10.2 Tenant's Compliance with Landlord's Fire and Casualty Insurance.
          ---------------------------------------------------------------  
Tenant shall, at Tenant's expense, comply with all reasonable insurance company
requirements pertaining to the use of the Premises.  If Tenant's conduct or use
of the Premises causes any increase in the premium for any insurance policies
carried by Landlord, then Tenant shall reimburse Landlord for any such increase.
To Landlord's knowledge, as of the date hereof Tenant's conduct or use of the
Premises does not cause any increase in such premiums.  Tenant, at Tenant's
expense, shall comply with all rules, orders, regulations or requirements of the
American Insurance Association (formerly the National Board of Fire
Underwriters) and with any similar body.

     10.3 Tenant's Insurance.  Tenant shall maintain the following coverages in

deduction for depreciation of the covered items and in amounts that meet any co-
insurance clauses of the policies of insurance and shall include a vandalism and
malicious mischief endorsement, sprinkler leakage coverage and earthquake
sprinkler leakage coverage.

additional insured; (ii) specifically cover the liability assumed by Tenant
under this Lease, including, but not limited to, Tenant's obligations under

days' prior written notice shall have been given to Landlord and any mortgagee
of Landlord; and (vi) contain a cross-liability endorsement or severability of
interest clause acceptable to Landlord.  Tenant shall deliver certificates of
such insurance to Landlord on or before the Lease Commencement Date and at least
thirty (30) days before the expiration dates thereof.

          -----------                                                     
insurance companies issuing property damage insurance waive any rights of
subrogation that such companies may have against Landlord or Tenant, as the case
may be.  As long as such waivers of subrogation are contained in their
respective insurance policies, Landlord and Tenant hereby waive any right that
either may have against the other on account of any loss or damage to their
respective property to the extent such loss or damage is insurable under
policies of insurance for fire and all risk coverage, theft, or other similar
insurance, whether or not the coverages required hereunder are in fact
maintained.

injury, personal injury and damage to property with such minimum limits as
prudent owners of comparable property in Newport Beach, California from time to
time carry, (b) a policy of "all-risk" property insurance for the full
replacement value of the Project, with such commercially reasonable deductibles
as Landlord may determine to be appropriate, and (c) such other insurance as

notify Landlord of any damage to the Premises resulting from fire or any other
casualty.  If the Premises, any Common Areas serving or providing access to the

casualty, Landlord shall promptly and diligently, subject to reasonable delays
for insurance adjustment or other matters beyond Landlord's reasonable control,
and subject to all other terms of this Article 11, restore the damaged areas.

casualty, except for modifications required by zoning and building codes and
other laws or any other modifications to the Common Areas deemed desirable by
Landlord, all of which modifications shall be Landlord's responsibility,
provided access to the Premises and any common restrooms serving the Premises
shall not be materially impaired.  Notwithstanding any other provision of this
Lease, upon the occurrence of any damage to the Premises, Tenant shall assign to
Landlord (or to any party designated by Landlord) all

Section 10.3 of this Lease with respect to the Tenant Improvements only, and
- ------------
Landlord shall repair any injury or damage to the Tenant Improvements installed
in the Premises and shall return such Tenant Improvements to their original
condition; provided that if the cost of such repair by Landlord exceeds the
amount of insurance proceeds received by Landlord from Tenant's insurance
carrier, as assigned by Tenant, the cost of such repairs shall be paid by Tenant
to Landlord prior to Landlord's repair of the damage. In connection with such
repairs and replacements, Tenant shall, prior to the commencement of
construction, submit to Landlord, for Landlord's review and approval, all plans,
specifications and working drawings relating thereto, and Landlord shall select
the contractors to perform such improvement work. Such submittal of plans and
construction of improvements shall be performed in substantial compliance with
the terms of the Tenant Work Letter as though such construction of improvements
were the initial construction of the Tenant Improvements. Landlord shall not be
liable for any inconvenience or annoyance to Tenant or its visitors, or injury
to Tenant's business resulting in any way from such damage or the repair
thereof; provided however, that if such fire or other casualty shall have
damaged the Premises or Common Areas necessary to Tenant's occupancy, Landlord
shall allow Tenant a proportionate abatement of Rent to the extent Landlord is
reimbursed from the proceeds of rental interruption insurance purchased by
Landlord as part of Operating Expenses, during the time and to the extent the
Premises are unfit for occupancy for the purposes permitted under this Lease,

Premises, Building and/or Project and instead terminate this Lease by notifying
Tenant in writing of such termination within sixty (60) days after the date of
damage, such notice to include a termination date giving Tenant ninety (90) days
to vacate the Premises, but Landlord may so elect only if the Building or
Project shall be damaged by fire or other casualty or cause, whether or not the
Premises are affected, and one or more of the following conditions is present:
(i) repairs cannot reasonably be completed within one hundred eighty (180) days
of the date of damage (when such repairs are made without the payment of
overtime or other premiums); (ii) the holder of any mortgage on the Building or
Project or ground lessor with respect to the Building or Project shall require
that the insurance proceeds be used to retire the mortgage debt, or shall
terminate the ground lease, as the case may be; or (iii) the damage is not fully
covered, except for deductible amounts not to exceed Two Hundred Fifty Thousand
Dollars ($250,000), by Landlord's insurance policies.

     11.3 Waiver of Statutory Provisions.  The provisions of this Lease,

including this Article 11, constitute an express agreement between Landlord and

Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any
rights or obligations concerning damage or destruction in the absence of an
express agreement between the parties, and any other statute or regulation, now
or hereafter in effect, shall have no application to this Lease or any damage or
destruction to all or any part of the Premises, the Building or any other
portion of the Project.

any substantial extent (i.e., $250,000 or more to repair or replace) during the

     No waiver of any provision of this Lease by either party shall be implied
by any failure of such party to enforce any remedy on account of the  violation
of such provision, even if such violation shall continue or be repeated
subsequently, any waiver by either party of any provision of this Lease may only
be in writing, and no express waiver shall affect any provision other than the
one specified in such waiver and that one only for the time and in the manner
specifically stated.  No receipt of monies by Landlord from Tenant after the
termination of this Lease shall in any way alter the length of the Lease Term or
of Tenant's right of possession hereunder or after the giving of any notice
shall reinstate, continue or extend the Lease Term or affect any notice given
Tenant prior to the receipt of such monies, it being agreed that after the
service of notice or the commencement of a suit or after final judgment for
possession of the Premises, Landlord may receive and collect any Rent due, and
the payment of said Rent shall not waive or affect said notice, suit or
judgment.  No payment by Tenant or receipt or acceptance by Landlord of a lesser
amount than the correct Rent due shall be deemed to be other than a payment on
account, nor shall any endorsement or statement on any check or any letter
accompanying any check or payment be deemed an accord and satisfaction, and
Landlord may accept such check or payment without prejudice to Landlord's right
to recover the balance, treat such partial payment as a default or pursue any
other remedy provided in this Lease or at law.

     If twenty-five percent (25%) or more of the Premises, the Building or the
Project shall be taken by power of eminent domain or condemned by any competent
authority for any public or quasi-public use or purpose, or if access to the
Premises is substantially impaired, or if Landlord shall grant a deed or other
instrument in lieu of such taking by eminent domain or condemnation, either
party shall have the option to terminate this Lease upon sixty (60) days'
notice, provided such notice is given no later than ninety (90) days after the
date of such taking, condemnation, reconfiguration, vacation, deed or other
instrument.  Landlord shall be entitled to receive the entire award or payment
in connection therewith, except that Tenant shall have the right to file any
separate claim available to Tenant for any taking of Tenant's personal property
and fixtures belonging to Tenant and removable by Tenant upon expiration of the
Lease Term pursuant to the terms of this Lease, alterations and improvements
paid for by Tenant from sources other than the Tenant Improvement Allowance and
Tenant is not otherwise reimbursed by Landlord therefor and for moving expenses.
All Rent shall be apportioned as of the date of such termination, or the date of
such taking (i.e., the date the condemning authority requires possession),
whichever shall first occur.  If any part of the Premises shall be taken, and
this Lease shall  not be so terminated, the Rent shall be proportionately
abated.  Tenant hereby waives any and all rights it might otherwise have
pursuant to Section 1265.130 of the California Code of Civil Procedure.

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

     14.1 Transfers.  Except as specifically permitted by Section 14.7 hereof,
          ---------                                       ------------        
Tenant shall not, without the prior written consent of Landlord, assign,
mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or
otherwise transfer, this Lease or any interest hereunder, permit any assignment
or other such foregoing transfer of this Lease or any interest hereunder by
operation of law, sublet the Premises or any part thereof, or permit the use of
the Premises by any persons other than Tenant and its employees (all of the
foregoing are hereinafter sometimes referred to collectively as  "Transfers" and
any person to whom any Transfer is made or sought to be made is hereinafter
sometimes referred to as a  "Transferee").  If Tenant shall desire Landlord's
consent to any  Transfer, Tenant shall notify Landlord in writing, which notice
(the "Transfer Notice") shall include (i) the proposed effective date of the
Transfer, which shall not be less than thirty (30) days nor more than one
hundred eighty (180) days after the date of delivery of the Transfer Notice,
(ii) a description of the portion of the Premises to be transferred (the
"Subject Space"), (iii) all of the terms of the proposed Transfer and the
consideration therefor, including a calculation of the "Transfer Premium," as
that term is defined in Section 14.3, below, in connection with such Transfer,
                        ------------                                          
the name and address of the proposed Transferee, and a copy of all existing
and/or proposed documentation pertaining to the proposed Transfer, including all
existing operative documents to be executed to evidence such Transfer, (iv)
current financial statements of the proposed Transferee certified by an officer,
partner or owner thereof, and any other information reasonably required by
Landlord, which will enable Landlord to determine the financial responsibility,
character, and reputation of the proposed Transferee, nature of such
Transferee's business and proposed use of the Subject Space, and (v) an executed
estoppel certificate from Tenant in the form attached hereto as Exhibit E.  Any
                                                                ---------      
Transfer made without Landlord's prior written consent shall, at Landlord's
option, be null, void and of no effect, and shall, at Landlord's option,
constitute a default by Tenant under Section 19.1.7 of this Lease.  Whether or
                                     --------------                           
not Landlord shall grant consent, Tenant shall pay Landlord's review and
processing fees, as well as any reasonable legal fees incurred by Landlord,
within thirty (30) days after written request by Landlord, all in an aggregate
amount not more than $2,500 per Transfer.

     14.2 Landlord's Consent.  Landlord shall not unreasonably withhold its
          ------------------                                               
consent to any proposed Transfer of the Subject Space to the Transferee on the
terms specified in the Transfer Notice.  The parties hereby agree that it shall
be deemed to be reasonable under this Lease and under any applicable law for
Landlord to withhold consent to any proposed Transfer where one or more of the
following apply, without limitation as to other reasonable grounds for
withholding consent:


          14.2.1  The Transferee is of a character or reputation or engaged in a
business which is not consistent with the quality of the Building or the
Project;

          14.2.2  [Intentionally omitted.]

          14.2.3  The Transferee's intended use of the Premises is inconsistent
with the permitted use specified in Article 5 above;
                                    ---------       

          14.2.4  The Transferee is not a party of reasonable financial worth
and/or financial stability in light of the responsibilities involved under the
Lease on the date consent is requested;

          14.2.5  The proposed Transfer would cause Landlord to be in violation
of another lease or agreement to which Landlord is a party, or would give an
occupant of the Project a right to cancel its lease;

                                       26

pursuant to Section 14.7 hereof, the terms of the proposed Transfer will allow
            -----------                                                       
the Transferee to exercise a right of renewal, right of expansion, right of
first offer, or other similar right held by Tenant (or will allow the Transferee
to occupy space leased by Tenant pursuant to any such right);

          14.2.7  [Intentionally omitted.]

          14.2.8  The Transferee does not intend to occupy the entire Premises
and conduct its business therefrom for a substantial portion of the term of the
Transfer; or

          14.2.9  The rent charged by Tenant to such Transferee during the term
of such Transfer (the "Transferee's Rent"), calculated using a present value
analysis, is less than eighty percent (80%) of the rent being obtained by
Landlord at the time of such Transfer, based on Landlord's most recent
transactions for comparable space in the Project for a comparable term (the
"Quoted Rent"), calculated using a present value analysis.

          If Landlord consents to any Transfer pursuant to the terms of this
Section 14.2 (and does not exercise any recapture rights Landlord may have under
- ------------

such Transfer of the Premises or portion thereof, upon substantially the same
terms and conditions as are set forth in the Transfer Notice furnished by Tenant
to Landlord pursuant to Section 14.1 of this Lease, provided that if there are
                        ------------                                          
any changes in the terms and conditions from those specified in the Transfer
Notice (i) such that Landlord would initially have been entitled to refuse its
consent to such Transfer under this Section 14.2, or (ii) which would cause the
                                    ------------                               
proposed Transfer to be more favorable to the Transferee than the terms set
forth in Tenant's original Transfer Notice, Tenant shall again submit the
Transfer to Landlord for its approval and other action under this Article 14
                                                                  ----------

          ----------------                                ------------    
Landlord consents to a Transfer, as a condition thereto which the parties hereby
agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any
"Transfer Premium," as that term is defined in this Section 14.3, received by
                                                    ------------             
Tenant from such Transferee. "Transfer Premium" shall mean all rent, additional
rent or other consideration payable by such Transferee in excess of (x) the Rent
and Additional Rent payable by Tenant under this Lease, plus (y) the broker's
commission which Tenant actually in good faith pays to obtain the Transferee;
any Economic Concessions (defined below) granted by Tenant to the Transferee;
reasonable attorneys' fees incurred by Tenant in preparing the assignment or
sublease, as the case may be, and in obtaining Landlord's consent thereto
(excluding fees incurred in litigating or arbitrating rent or profit issues);
and the unamortized cost of the tenant improvements constructed for the
Transferee to the extent paid by Tenant, prorated to the amount of space subject
to a sublease, but without proration in the case of an assignment.  For purposes
of this Section 14.3, "Economic Concessions"  shall include, without limitation,
        ------------                                                            
annual rental rates and escalations, rent abatement concessions, tenant
improvements or allowances, payment of broker's fees and commissions (if any),
moving allowances, buy-outs of prior leases, payment or reimbursement of
termination fees for prior leases, the value of extraordinary services, free or
reduced rate parking privileges, reduced rent or free rent, options to extend at
fixed or below market rates, and all other concessions having economic value.
In calculating the profits under this Section 14.3, Tenant shall deliver to
                                      ------------                         
Landlord a detailed description of the profit calculation, with the division of
profit being on a monthly basis, and with an annual reconciliation and a right
of Landlord to audit, in the same manner and within the same time as Tenant's
right to audit set forth in Section 4.7 hereof with respect to Operating
                            -----------                                 
Expenses.  The Transfer Premium shall be determined, on a per rentable square
foot basis if less than all of the Premises is transferred.  "Transfer Premium"
shall also include, but not be limited to, key money and bonus money paid by
Transferee to Tenant in connection with such Transfer, and any payment in excess
of fair market value for services rendered by Tenant to Transferee or 

                                       27

for assets, fixtures, inventory, equipment, or furniture transferred by Tenant
to Transferee in connection with such Transfer. In the calculations of the Rent
(as it relates to the Transfer Premium calculated under this Section 14.3), and
                                                             ------------
the Transferee's Rent and Quoted Rent under Section 14.2.9 of this Lease, the
                                            --------------
Rent paid during each annual period for the Subject Space by Tenant, and the
Transferee's Rent and the Quoted Rent, shall be computed after adjusting such
rent to the actual effective rent to be paid, taking into consideration any and
all leasehold concessions granted in connection therewith, including, but not
limited to, any rent credit and tenant improvement allowance. For purposes of
calculating any such effective rent, all such concessions shall be amortized on
a straight-line basis over the relevant term.

     14.4 Landlord's Option as to Subject Space.  Notwithstanding anything to
          -------------------------------------                              
the contrary contained in this  Article 14, Landlord shall have the option, by

giving written notice to Tenant within thirty (30) days after receipt of any
Transfer Notice, to (i) recapture the Subject Space, or (ii) take an assignment
or sublease of the Subject Space from Tenant; provided however, Tenant shall
have the right to rescind Tenant's Transfer Notice by written notice to Landlord
given within fifteen (15) days after Landlord notifies Tenant of Landlord's
exercise of Landlord's rights under this sentence, and in such event Tenant's
Transfer Notice shall be void ab initio and of no further force or effect
                              -- ------                                  
whatsoever.  If Tenant rescinds any such Transfer Notice, Landlord shall not
have the rights set forth in the first sentence of this Section 14.4.  Such
                                                        ------------       
recapture, or sublease or assignment notice shall cancel and terminate this
Lease, or create a sublease or assignment, as the case may be, with respect to
the Subject Space as of the date stated in the Transfer Notice as the effective
date of the proposed Transfer until the last day of the term of the Transfer as
set forth in the Transfer Notice.  In the event of a recapture by Landlord, if
this Lease shall be canceled with respect to less than the entire Premises, the
Rent reserved herein shall be prorated on the basis of the number of rentable
square feet retained by Tenant in proportion to the number of rentable square
feet contained in the Premises, and this Lease as so amended shall continue
thereafter in full force and effect, and upon request of either party, the
parties shall execute written confirmation of the same.  If Landlord declines,
or fails to elect in a timely manner to recapture, sublease or take an
assignment of the Subject Space under this Section 14.4, then, provided Landlord
                                           ------------                         
has consented to the proposed Transfer or not responded within five (5) days
after the date a second notice given to Landlord by Tenant at any time after
thirty (30) days after receipt of the information required pursuant to Section
                                                                       -------

responds, Tenant shall be entitled to proceed as set forth in this sentence),
then Tenant shall be entitled to proceed to transfer the Subject Space to the
proposed Transferee, subject to the provisions of the last paragraph of Section
                                                                        -------

(and except for any assignment or subletting with an effective date occurring
during the last twenty-four (24) months of the Lease Term, including any
extended Term if Tenant has exercised Tenant's option to extend the Term of this
Lease pursuant to Section 2.2 hereof), Landlord shall not have the right to
                  -----------                                              
recapture, or take an assignment or sublease, of the Subject Space pursuant to
clauses (i) or (ii), above, of this Section 14.4 if Landlord does not agree, in
                                    ------------                               
Landlord's reasonable discretion, to allow Tenant to expand the size of the
Premises beyond the size permitted by Section 1.1.6.4 of this Lease.
                                      ---------------               

     14.5 Effect of Transfer.  If Landlord consents to a Transfer, (i) the terms

and conditions of this Lease shall in no way be deemed to have been waived or
modified, (ii) such consent shall not be deemed consent to any further Transfer
by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord,
promptly after execution, an original executed copy of all documentation
pertaining to the Transfer in form reasonably acceptable to Landlord, (iv)
Tenant shall furnish upon Landlord's request a complete statement, certified by

setting forth in detail the computation of any Transfer Premium Tenant has
derived and shall derive from such Transfer, and (v) no Transfer relating to
this Lease or agreement entered into with respect thereto, whether with or
without Landlord's consent, shall relieve Tenant or any guarantor of the Lease
from liability under this Lease.  Landlord or its authorized representatives
shall have the right at all reasonable times to audit the books, records and
papers of Tenant relating to any Transfer, and shall have the right to make
copies thereof.  If the Transfer Premium respecting any Transfer shall be found

                                       28
<PAGE>
 
understated, Tenant shall, within thirty (30) days after demand, pay the
deficiency and Landlord's costs of such audit, if understated by more than ten
percent (10%).  Any such audit must be within the time period specified in
Section 4.7.

     14.6 Additional Transfers.  For purposes of this Lease, the term "Transfer"
          --------------------

hypothecation or pledge of more than an aggregate of fifty percent (50%) of the
value of the unencumbered assets of Tenant within a twelve (12) month period.

     14.7 Non-Transfers.  Notwithstanding anything to the  contrary contained in
          -------------                                                         
this Lease, neither (i) an assignment to a transferee of all or substantially
all of the assets of Tenant, (ii) an assignment of the Premises to a transferee
which is the resulting entity of a merger or consolidation of Tenant with
another entity, nor (iii) an assignment or subletting of all or a portion of the
Premises to an "Affiliated" of Tenant (an entity which is controlled by,
controls, or is under common control with, Tenant), shall be deemed a Transfer

such assignment or sublease within twenty (20) days after such assignment or
subletting and promptly supplies Landlord with any documents or information
reasonably requested by Landlord regarding such transfer or transferee as set
forth in items (i) through (iii) above, that such assignment or sublease is not
a subterfuge by Tenant to avoid its obligations under this Lease, that if an
assignment, the transferee assumes in full, in writing, the obligations of
Tenant under this Lease accruing after the date of the Transfer (or if a
sublease, the sublessee of a portion of the Premises or Term assumes, in full
the obligations of Tenant with respect to such portion), in writing, and in each
case a copy of such assumption is delivered to Landlord prior to the date of the
assignment or subletting, and except for an assignment permitted under this

with generally accepted accounting principles (the "Net Worth") in an amount

acceptance by Landlord of a surrender of the Premises unless such intent is
specifically acknowledged in a writing signed by Landlord.  The delivery of keys
to the Premises to Landlord or any agent or employee of Landlord shall not
constitute a surrender of the Premises or effect a termination of this Lease,
whether or not the keys are thereafter retained by Landlord, and notwithstanding
such delivery Tenant shall be entitled to the return of such keys at any
reasonable time upon request until this Lease shall have been terminated.  The

a mutual termination hereof, shall not work a merger, and at the option of

possession and as thereafter improved by Landlord and/or Tenant, reasonable wear
and tear and repairs which are specifically made the responsibility of Landlord
hereunder excepted.  Upon such expiration or termination, Tenant shall, without
expense to Landlord, remove or cause to be removed from the Premises all debris
and rubbish, and such items of furniture, equipment, free-standing cabinet work,
and other articles of personal property owned by Tenant or installed or placed
by Tenant at its expense in the Premises, and such similar articles of any other
persons claiming under Tenant, as Tenant elects to remove or Landlord may, in
its sole discretion, require to be removed, and Tenant shall repair at its own
expense all damage to the Premises and Building resulting from such removal.
Notwithstanding anything herein to the contrary, Tenant shall have the right to
remove all items which bear any name, logo or other material proprietary to
Tenant.

     If Tenant holds over after the expiration of the Lease Term hereof, with or
without the express or implied consent of Landlord, such tenancy shall be from
month-to-month only, and shall not constitute a renewal hereof or an extension
for any further term, and in such case Rent shall be payable at a monthly rate

rental period of the Lease Term under this Lease. Such month-to-month tenancy

If Tenant fails to surrender the Premises upon the termination or expiration of
this Lease, in addition to any other liabilities to Landlord accruing therefrom,
Tenant shall protect, defend, indemnify and hold Landlord harmless from all
loss, costs (including reasonable attorneys' fees) and liability resulting from
such failure, including, without limiting the generality of the foregoing, any
claims made by any succeeding tenant founded upon such failure to surrender, and
any lost profits to Landlord resulting from such failure to surrender, provided
that Landlord notifies Tenant in writing of the general nature of such liability
within ten (10) days after Tenant requests that Landlord do so.

     Within fifteen (15) days following a request in writing by Landlord, Tenant

instruments may be reasonably required for such purposes.  In connection
therewith, Landlord may require Tenant to provide Landlord with a current

current financial statement year, which statements may be the publicly
disseminated statements of PIMCO Advisors, L.P. so long as such entity is a
constituent general partner of Tenant and the Tenant is the original Tenant

generally accepted accounting principles and, if such is the normal practice of

     This Lease is subject and subordinate to all present and future ground or

trust deeds, now or hereafter in force against the Building or Project, if any,
and to all renewals, extensions, modifications, consolidations and replacements
thereof, and to all advances made or hereafter to be made upon the security of
such mortgages or trust deeds, unless the holders of such mortgages or trust
deeds, or the lessors under such ground lease or underlying leases, require in
writing that this Lease be superior thereto.  Tenant covenants and agrees in the
event any proceedings are brought for the foreclosure of any such mortgage, to
attorn, without any deductions or set-offs other than as specifically provided
in this Lease, to the purchaser upon any such foreclosure sale if so  requested
to do so by such purchaser, and to recognize such purchaser as the lessor under
this Lease.  Tenant shall, within thirty (30) days of request by Landlord,
execute such further instruments or assurances as Landlord may reasonably deem
necessary to evidence or confirm the subordination or superiority of this Lease
to any such mortgages, trust deeds, ground leases or underlying leases; provided
however, Landlord agrees to provide Tenant with commercially reasonable
subordination, non-disturbance and attornment agreement(s) in favor of Tenant
from any ground lessors, mortgagees or lien holders of Landlord with respect to
the Building as a condition precedent to Tenant's agreement to be bound by the
future subordination of this Lease.  Tenant waives the provisions of any current
or future statute, rule or law which may give or purport to give Tenant any
right or election to terminate or otherwise adversely affect this Lease and the
obligations of the Tenant hereunder in the event of any foreclosure proceeding
or sale.  Landlord represents and warrants that the Building is not currently
encumbered by any mortgage or deed of trust.

Landlord shall have, in addition to any other remedies available to Landlord at
law or in equity, the option to pursue any one or more of the following
remedies, each and all of which shall be cumulative and nonexclusive, without
any notice or demand whatsoever.

          19.2.1  Terminate this Lease, in which event Tenant shall immediately
surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may,
without prejudice to any other remedy which it may have for possession or
arrearages in rent, enter upon and take possession of the Premises and expel or
remove Tenant and any other person who may be occupying the Premises or any part
thereof, without being liable for prosecution or any claim or damages therefor;
and Landlord may  recover from Tenant the following:

                     (i)   The worth at the time of award of any unpaid rent
which has been earned at the time of such termination; plus

                     (ii)  The worth at the time of award of the amount by which
the unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                     (iii) The worth at the time of award of the amount by
which the unpaid rent for the balance of the Lease Term after the time of award
exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                     (iv)  Any other amount necessary to compensate Landlord for
all the detriment proximately caused by Tenant's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, specifically including but not limited to, brokerage
commissions and advertising expenses incurred, expenses of remodeling the
Premises or any portion thereof for a new tenant, whether for the same or a
different use, and any special concessions made to obtain a new tenant; and

<PAGE>
 
                     (v)   At Landlord's election, such other amounts in
addition to or in lieu of the foregoing as may be permitted from time to time by
applicable law.

          The term "rent" as used in this Section 19.2 shall be deemed to be and
                                          ------------                          
to mean all sums of every nature required to be paid by Tenant pursuant to the
terms of this Lease, whether to Landlord or to others.  As used in Paragraphs
19.2.1(i) and (ii), above, the "worth at the time of award" shall be computed by
allowing interest at the rate set forth in Article 25 of this Lease, but in no
                                           ----------                         
case greater than the maximum amount of such interest permitted by law.  As used
in Paragraph 19.2.1(iii) above, the "worth at the time of award" shall be
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of award plus one percent (1%).

          19.2.2  Landlord shall have the remedy described in California Civil
Code Section 1951.4 (lessor may continue lease in effect after lessee's breach
and abandonment and recover Rent as it becomes due, if lessee has the right to
sublet or assign, subject only to reasonable limitations).  Accordingly, if
Landlord does not elect to terminate this Lease on account of any default by
Tenant, Landlord may, from time to time, without terminating this Lease, enforce
all of its rights and remedies under this Lease, including the right to recover
all rent as it becomes due.

     19.3 Subleases of Tenant.  Whether or not Landlord elects to terminate this

Landlord shall have the right to terminate any and all subleases, licenses,
concessions or other consensual arrangements for possession entered into by
Tenant and affecting the Premises or may, in Landlord's sole discretion, succeed
to Tenant's interest in such subleases, licenses, concessions or arrangements.
In the event of Landlord's election to succeed to Tenant's interest in any such
subleases, licenses, concessions or arrangements, Tenant shall, as of the date
of notice by Landlord of such election, have no further right to or interest in
the rent or other consideration receivable thereunder.

     19.4 Form of Payment After Default.  Following the occurrence of a default
          -----------------------------                                        
by Tenant, and until the cure of such defaults, Landlord shall have the right to
require that any or all subsequent amounts paid by Tenant to Landlord hereunder,
whether in the cure of the default in question or otherwise, be paid in the form
of cash, money order, cashier's or certified check drawn on an institution
acceptable to Landlord, or by other means approved by Landlord, notwithstanding
any prior practice of accepting payments in any different form.

     19.5 Efforts to Relet.  For the purposes of this Article 19, Tenant's right
          ----------------                            ----------                
to possession shall not be deemed to have been terminated by efforts of Landlord
to relet the Premises, by its acts of maintenance or preservation with respect
to the Premises, or by appointment of a receiver to protect Landlord's interests
hereunder.  The foregoing enumeration is not exhaustive, but merely illustrative
of acts which may be performed by Landlord without terminating Tenant's right to
possession.

     19.6 Landlord's Default.  Landlord shall not be in default in the
          ------------------                                          
performance of any obligation required to be performed by Landlord under this
Lease, and Tenant shall have no right to any remedy for such failed obligation
available under this Lease, at law or otherwise, unless Landlord has failed to
perform such obligation within a commercially reasonable time period (which
shall not exceed fifteen (15) days unless the time to cure such failure requires
more than fifteen (15) days in which event Landlord must commence to cure within
such fifteen (15) day period and thereafter diligently pursue the same to
completion) after the receipt of written notice from Tenant specifying in detail
Landlord's failure to perform; provided, however, if, during such commercially
reasonable time period, Landlord neither cures the failed obligation nor
commences performance and thereafter diligently and continuously proceeds to
cure such failed obligation, then Landlord shall be in default in the
performance of such obligation required to be performed under this Lease, and
Tenant may cure Landlord's default for the account and at the expense of
Landlord and render a bill to Landlord for such expense. If Landlord fails 

                                       33
<PAGE>
 
to pay such bill within thirty (30) days after it is rendered, Tenant may bring
suitable legal action to require Landlord to pay such bill. If the final
judgment of such action determines that Landlord was in default, and that Tenant
in curing the default reasonably incurred an expense, or if Landlord agrees in
writing that Tenant may do so with respect to the amount of the deduction,
Tenant, in addition to its normal remedies, but subject to the provisions of
Section 29.10 of this Lease (which Section 29.10 shall prevail in the event of a
- -------------                      -------------
conflict with this Section 19.6), may deduct the amount of the final judgment,
                   ------------
together with interest as set forth in the following sentence, or the amount so
approved by Landlord, as the case may be, from the Base Rent and any other
amounts payable by Tenant hereunder to Landlord until Tenant has recovered all
of such amount. The amount to be paid by Landlord shall include interest on the
judgment at the reference rate of interest of Bank of America, N.T.&S.A., not to
exceed the highest rate permitted by applicable law, from the date Tenant paid
the expense to the date of payment by Landlord to Tenant. In addition, but
subject to the provisions of Section 29.10 hereof, Tenant may exercise such
                             -------------
rights or remedies that shall be provided or permitted by law to recover any
damages proximately caused by such default, and, at Tenant's election, and after
five (5) business days' written notice to Landlord of such election, Tenant may
offset all or any portion of such award against any obligation due and owing by
Tenant to Landlord under this Lease.

security deposit (the "Security Deposit") in the amount set forth in Section 10

letter of credit, the Security Deposit may be in the form of an unconditional,
irrevocable standby letter of credit issued by a nationally recognized financial
institution having at least One Hundred Million Dollars ($100,000,000.00) in
capital, which provides that Landlord can draw on the letter of credit subject
only to Landlord's delivery of a certification that Landlord is entitled to do
so pursuant to this Article 21.  Landlord shall have the right to approve the

financial institution issuing the letter of credit, which approval shall not be
unreasonably withheld.  The Security Deposit shall be held by Landlord as
security for the faithful performance by Tenant of all the terms, covenants, and
conditions of this Lease to be kept and performed by Tenant during the Lease
Term.  If Tenant defaults with respect to any provisions of this Lease,
including, but not limited to, the provisions relating to the payment of Rent,
Landlord may, but shall not be required to, use, apply or retain all or any part
of the Security Deposit for the payment of any Rent or any other sum in default,
or for the payment of any amount that Landlord may spend or become obligated to
spend by reason of Tenant's default, or to compensate Landlord for any other
loss or damage that Landlord may suffer by reason of Tenant's default.  If any
portion of the Security Deposit is so used or applied, Tenant shall, within ten
(10) days after written demand therefor, provide a replacement letter of credit
in the required amount, and Tenant's failure to do so shall be a default under
this Lease.  If Tenant shall fully and faithfully perform every provision of
this Lease to be performed by it, the Security Deposit, or any balance thereof,
shall be returned to Tenant, or, at

Landlord's option, to the last assignee of Tenant's interest hereunder, within
thirty (30) days following the expiration of the Lease Term. Tenant shall not be
entitled to any interest on the Security Deposit. Tenant hereby waives the
provisions of Section 1950.7 of the California Civil Code, and all other
provisions of law, now or hereafter in force, which provide that Landlord may
claim from a security deposit only those sums reasonably necessary to remedy
defaults in the payment of rent, to repair damage caused by Tenant or to clean
the Premises, it being agreed that Landlord may, in addition, claim those sums
reasonably necessary to compensate Landlord for any other loss or damage,
foreseeable or unforeseeable, caused by the act or omission of Tenant or any
officer, employee, agent or invitee of Tenant.

($300) per month, which rental rates shall increase on the first day of the
fourth Lease Year and on the first day of every third (3rd) anniversary
thereafter by twenty percent (20%) over the monthly rental in effect prior to
the date of such increase.  Tenant's installation and operation of the Antenna
shall be conditioned upon Tenant fulfilling, at Tenant's sole cost and expense,
the following obligations:

          (a) Tenant's right to install, operate and maintain the Antenna shall
be subject to all governmental laws, rules and regulations (including without
limitation, applicable building codes and any regulations promulgated by all
applicable governmental authorities).  Landlord agrees, at no cost or liability
to Landlord, to cooperate with Tenant in Tenant obtaining all required
governmental permits and licenses for the Antenna.

          (b) All costs of installation, operation, insuring and maintenance of
the Antenna and any connecting cable (including, without limitation, costs of
obtaining any necessary permits and any and all costs of electricity
attributable to the Antenna) shall be borne by Tenant directly.  Tenant and
Tenant's agents, employees and contractors shall have the right of access to the
roof of the Building upon reasonable prior notice to Landlord (including oral
notice to Landlord or the security office of the Building), at any time to
inspect, maintain, repair and replace the Antennae; provided however, any such
activity which disrupts or would disrupt tenants of the Building shall be
conducted after business hours.

          (c) It is expressly understood that Landlord retains the right to use
by Landlord or others the roof of the Building for any purpose whatsoever
provided that Landlord shall not unreasonably interfere with the use or
operation of the Antenna.

                                       35

          (d) Tenant shall use the Antenna so as not to cause any unreasonable
interference to other tenants in the Building or with any other
telecommunication equipment and not to damage or interfere with the normal
operation of the Building.

          (e) Landlord shall not have any obligation with respect to the
maintenance or repair of the Antenna nor shall Landlord be responsible for any
damage that may be caused to Tenant or the Antenna whether caused by any other
tenant in or occupant of the Building or otherwise, except to the extent caused
by the negligence or willful action of Landlord or Landlord's agents, employees
or contractors.  Landlord makes no representation that the Antenna will be able
to receive or transmit communication signals without interference or disturbance
and Tenant agrees that Landlord shall not be liable to Tenant therefor.

          (f) Tenant shall (i) be solely responsible for any damage related to
the Antenna, including damage to the Building, (ii) promptly pay any tax,
license or permit fees charged pursuant to any laws or regulations in connection
with the installation, maintenance or use of the Antenna and comply with all
precautions and safeguards recommended by all governmental authorities, and
(iii) pay for all necessary repairs, replacements or maintenance of the Antenna.

          (g) Tenant shall remove the Antenna and connecting cable at Tenant's
sole cost upon the expiration or earlier termination of this Lease or upon the
imposition of any governmental law or regulation which may require removal, and
shall repair the roof of the Building upon such removal to the extent required
by such work of removal.

          (h) In no event shall any Antenna, or any part thereof, extend above
the parapet wall surrounding the rooftop of the Building, and the Antenna shall
consist of equipment, machinery and appurtenances generally comparable to that
installed atop the Building.

          ------                                                             
contractors shall have access to the Building and the Premises for the purpose
of planning Tenant's work in the Premises and installing Tenant's fixtures and
equipment in the Premises subject to Landlord's reasonable rules and regulations
governing such access. Any inspection or work to be performed by Tenant or
Tenant's architects, engineers, consultants or contractors within the Premises
shall be done so as not to interfere with any work being performed by Landlord
or Landlord's contractors at the Premises and shall be subject to Landlord's
construction rules and regulations in effect from time to time, a copy of which
currently effective construction rules and regulations have been delivered to
Tenant. Landlord, at no cost to Tenant, shall provide use of Landlord's freight
elevators, parking facilities, loading docks, electricity, water and related
facilities at the Building as may reasonably be necessary to enable Tenant and
Tenant's architects, engineers, consultants and contractors to perform such
inspection and work; provided however, that Tenant shall be responsible and
liable to Landlord and Landlord's contractor for any damage done to such
facilities by Tenant or Tenant's architects, engineers, consultants or
contractors in using same. Such access shall be in the nature of a license and
shall be automatically revoked upon any termination or cancellation of this
Lease. Such access to the Building shall be had only during the normal hours of
construction on the Premises. In consideration of such license, Tenant shall
carry liability insurance as provided in Section 10.3 hereof. Tenant agrees to
                                         ------------
indemnify Landlord against and hold Landlord free and harmless from any and all
loss, cost, damage, claim or liability which may arise from any act or omission
of Tenant or Tenant's architects, engineers, consultants or contractors related
to such access to the Building. Any access to the Building by Tenant or Tenant's
architects, engineers, consultants or contractors shall be upon reasonable
advance telephonic notice to Landlord (not to exceed twenty-four (24) hours
advance notice). Subject to Landlord's prior written consent, which consent
shall not be unreasonably withheld or delayed, Tenant shall be entitled to use
the Building's existing shafts, risers and conduits (including unused portions
of the existing four (4) inch underground Telco conduit) between the Premises
and other portions of the Building (including the roof) for the purposes of
installation and 

                                       36

maintenance of conduits, cables, ducts, flues, pipes and similar devices for the
Antennae and other communications or data processing equipment, supplementary
heating, ventilating and air conditioning systems and similar uses consistent
with the Building being a first class office building and not interfering with
the use or occupancy of the Building by other tenants. Subject to the provisions
of Article 8 hereof (including without limitation Landlord's approval thereof),
   ---------
Tenant, at Tenant's expense, shall have the right to install a two (2) inch
underground conduit between the 800 Building and the 840 Building for use with
Tenant's fibre optics facilities.

of Tenant's telecommunications and computer systems, subject to Tenant complying
with all applicable governmental laws, rules and regulations (collectively, the
"Back-up Equipment").  The Back-up Equipment and an enclosure therefor (which
enclosure is to match the existing enclosure) shall be located as depicted on

Landlord, to cooperate with Tenant in Tenant obtaining all governmental permits
and licenses required for the installation and operation of the Back-up
Equipment and enclosure at such location.  All costs of installation, operation,
insuring and maintenance of the Back-up Equipment and any connecting cables and
conduits (including, without limitation, the cost of obtaining any necessary
permits or license and any all costs of electricity attributable to the Back-up
Equipment) shall be borne by Tenant.  Landlord shall not have any obligation
with respect to the maintenance or repair of the Back-up Equipment nor shall
Landlord be responsible for any damage that may be caused to Tenant or the Back-
up Equipment, other than that caused by the negligence or intentional action of
Landlord, its agents, employees or contractors.  Tenant, at Tenant's sole cost,
shall remove the Back-up Equipment and connecting cables and conduits (i.e.,
generator, enclosure and conduits to the Building electrical room) upon the
expiration or earlier termination of this Lease or upon the imposition of any
governmental law or regulation which may require such removal, and shall repair
the Building upon such removal to the extent required by such work of removal.

quality, design and style of the Building and Project, Tenant, if the Premises
comprise an entire floor of the Building, at its sole cost and expense, may
install identification signage anywhere in the Premises including in the
elevator lobby of the Premises, provided that such signs must not be visible
from the exterior of the Building.

     23.2 Multi-Tenant Floor Tenants.  If other tenants occupy space on the
          --------------------------                                       
floor on which the Premises is located, Tenant's identifying signage shall be
provided by Landlord, at Tenant's cost, and such signage shall be comparable to
that used by Landlord for other similar floors in the Building and shall comply
with Landlord's Building standard signage program.

     23.3 Prohibited Signage and Other Items.  Any signs, notices, logos,
          ----------------------------------                             
pictures, names or advertisements which are installed and that have not been
individually approved by Landlord may be removed without notice by Landlord at
the sole expense of Tenant. Tenant may not install any signs on the exterior or
roof of the Building or Project or the Common Areas. Any signs, window
coverings, or blinds (even if the same are located behind the Landlord approved
window coverings for the Building), or other items visible from the exterior of
the Premises or Building, as well as the Monument Sign (as defined below), are
subject to the prior written approval of Landlord, in Landlord's sole
discretion. Tenant shall be entitled to one (1) line of signage on the lobby

forty-five thousand (45,000) rentable square feet within the Building under this
Lease (the "Required Occupancy Level") and subject to satisfaction and
fulfillment of all "Sign Requirements" (as defined below), Tenant shall have the
non-exclusive right, at Tenant's sole expense, to install and maintain one panel
sign on the monument sign located on the Newport Center Drive side of the
Building (the "Monument Sign").  Tenant may transfer the right to the Monument
Sign to any "Affiliate" of Tenant (defined in Section 14.7) or permitted

Level so long as such transferee is of comparable reputation, standing and image
in the business community as the original Tenant executing this Lease, and is
not engaged in a business and does not hold a political orientation which, in
Landlord's reasonable good faith judgment, is disreputable or is inconsistent
with the quality of the Project.  Subject to Landlord's prior written approval
of the permitted transferee's changes to and replacements of the Monument Sign,
Landlord agrees that Landlord shall not withhold Landlord's approval to a sign
of comparable size to Tenant's original sign which uses Tenant's transferee's
name provided that the proposed sign is consistent with generally accepted
standards for signage in similar first class office projects in the Fashion
Island area of Newport Beach, California.  Tenant shall promptly remove Tenant's
panel on the Monument Sign and repair the monument as necessary due to such
removal, all at Tenant's sole cost and expense, immediately upon the termination
of this Lease or, upon written request of Landlord, upon Tenant's failure to
meet such Required Occupancy Level.  The size, style, graphics and type of the
Monument Sign shall match the existing signs on the Monument Sign and shall be
subject to any and all approvals and requirements and all applicable laws,
regulations and ordinances of the City of Newport Beach.  The cost of obtaining
any and all approvals of the City of Newport Beach and the cost of all
fabrication, installation, maintenance, insurance, removal and utilities, if
any, for Tenant's Monument Sign shall be paid by Tenant.  Landlord shall
cooperate in Tenant's efforts to comply with the Sign Requirements in order to
allow Tenant's Monument Sign to be installed.  Landlord does not warrant or
represent that Tenant's Monument Sign, or the plans and specifications therefor,
shall meet any and all approvals and requirements or any and all applicable
laws, regulations and ordinances of the City of Newport Beach.  The Sign
Requirements include all documents of record affecting the Building.  The only
third party approval of Tenant's panel sign on the Monument Sign, other than the
City of Newport Beach, is the approval of The Irvine Company.

     Tenant shall not do anything or suffer anything to be done in or about the
Premises which will in any way conflict with any law, statute, ordinance or
other governmental rule, regulation or requirement now in force or which may
hereafter be enacted or promulgated, including without limitation the ADA.  At

affecting the Premises, including corridors and restrooms, other than the making
of structural changes or changes to the Building's life safety system on all
floors on which Tenant leases the entire leasable area; provided however,
Landlord shall be responsible for compliance with all ADA requirements in effect
and applicable as of the Lease Commencement Date with respect to the restrooms
located on the fifth and sixth floors of the 800 Building.  Should any standard

hereunder; provided however, there shall be no late charge as to the first late

Rent and the right to require it shall be in addition to all of Landlord's other
rights and remedies hereunder or at law and shall not be construed as liquidated
damages or as limiting Landlord's remedies in any manner.  In addition to the
late charge described above, any Rent or other amounts owing hereunder which are
not paid on or before the date they are due shall thereafter bear interest until
paid at a rate per annum equal to twelve percent (12%) per annum, provided that

Notwithstanding anything to the contrary contained in this Article 27, Landlord

Landlord may make any such entries without the abatement of Rent unless Tenant
is thereby prevented from operating in the Premises for more than one (1)

willful misconduct of Landlord or Landlord's agents, contractors or employees,
Tenant hereby waives any claims for damages or for any injuries or inconvenience

unlawful entry into, or a detainer of, the Premises, or an actual or
constructive eviction of Tenant from any portion of the Premises.

conditioned upon Tenant abiding by all reasonable rules and regulations which
are prescribed from time to time for the orderly operation and use of the
parking facility where the passes are located and upon Tenant's cooperation in
seeing that Tenant's employees and visitors also comply with such rules and

facility in question at any time and Tenant acknowledges and agrees that
Landlord may, without incurring any liability to Tenant and without any
abatement of Rent under this Lease, from time to time, close-off or restrict
access to the parking facility in question for purposes of permitting or
facilitating any such construction, alteration or improvements. Landlord agrees

operator shall have all the rights of control delegated by Landlord. The parking

ground lessor for the Building or Project require a modification or
modifications of this Lease, which modification or modifications will not cause
an increased cost or expense to Tenant or in any other way adversely change the
rights and obligations of Tenant hereunder, then and in such event, Tenant
agrees that this Lease may be so modified and agrees to execute whatever
documents are required therefor and deliver the same to Landlord within twenty
(20) days following the request therefor.  Should Landlord or any such
prospective mortgagee or ground lessor require execution of a short form of
Lease for recording, containing, among other customary provisions, the names of
the parties, a description of the Premises and the Lease Term, Tenant agrees to
execute such short form of Lease and to deliver the same to Landlord within
twenty (20) days following the request therefor.  All documents pursuant to this
Section shall be prepared by Landlord at Landlord's cost.

     29.4 Transfer of Landlord's Interest.  Tenant acknowledges that Landlord
          -------------------------------                                    
has the right to transfer all or any portion of its interest in the Project or
Building and in this Lease, and Tenant agrees that in the event of any such
transfer and a transfer of the Security Deposit, Landlord shall automatically be
released from all liability under this Lease accruing after the effective date
of the transfer and Tenant agrees to look solely to such transferee for the
performance of Landlord's obligations hereunder after the date of transfer.
Landlord shall cause the transferee to assume such obligations in writing.
Tenant further acknowledges that Landlord may assign its interest in this Lease
to a mortgage lender as additional security and agrees that such an assignment
shall not release Landlord from its obligations hereunder and that Tenant shall
continue to look to Landlord for the performance of its obligations hereunder.

     29.5 Prohibition Against Recording.  Except as provided in Section 29.3 of
          -----------------------------                         ------------

between Landlord and Tenant other than the relationship of landlord and tenant.

            --------------- 
its provisions.

     29.9   Partial Invalidity.  If any term, provision or condition contained 
            ------------------   
in this Lease shall, to any extent, be invalid or unenforceable, the remainder
of this Lease, or the application of such term, provision or condition to
persons or circumstances other than those with respect to which it is invalid or
unenforceable, shall not be affected thereby, and each and every other term,
provision and condition of this Lease shall be valid and enforceable to the
fullest extent possible permitted by law.

     29.10  Landlord Exculpation.  It is expressly understood and agreed that
            --------------------                                             
notwithstanding anything in this Lease to the contrary, and notwithstanding any
applicable law to the contrary, the liability of Landlord Parties hereunder
(including any successor landlord) and any recourse by Tenant against Landlord
shall be limited solely and exclusively to the lesser of (a) the interest of
Landlord in the Project and the Building or (b) the equity interest Landlord
would have in and to the Project and Building if the Project and the Building
were encumbered by debt in an amount equal to eighty percent (80%) of the value
of the Project and the Building, and neither Landlord, nor any of its
constituent partners, shall have any personal liability therefor, and Tenant
hereby expressly waives and releases such personal liability on behalf of itself
and all persons claiming by, through or under Tenant.

     29.11  Entire Agreement.  It is understood and acknowledged that there are
            ----------------                                                   
no oral agreements between the parties hereto affecting this Lease and this
Lease supersedes and cancels any and all previous negotiations, arrangements,
brochures, agreements and understandings, if any, between the parties hereto or
displayed by Landlord to Tenant with respect to the subject matter thereof, and
none thereof shall be used to interpret or construe this Lease.  This Lease and
any side letter or separate agreement executed by Landlord and Tenant in
connection with this Lease and dated of even date herewith, the exhibits hereto
and the Storage Space Agreements contain all of the terms, covenants,
conditions, warranties and agreements of the parties relating in any manner to
the rental, use and occupancy of the Premises, shall be considered to be the
only agreement between  the parties hereto and their representatives and agents,
and none of the terms, covenants, conditions or provisions of this Lease can be
modified, deleted or added to except in writing signed by the parties hereto.

     29.12  Right to Lease.  Landlord reserves the absolute right to effect such
            --------------                                                      
other tenancies in the Project as Landlord in the exercise of its sole business
judgment shall determine to best promote the interests of the Project.  Tenant
does not rely on the fact, nor does Landlord represent, that any specific tenant
or type or number of tenants shall, during the Lease Term, occupy any space in
the Project.

     29.13  Force Majeure.  Any prevention, delay or stoppage due to strikes,
            -------------                                                    
lockouts, labor disputes, acts of God, inability to obtain services, labor, or
materials or reasonable substitutes therefor, governmental actions, civil
commotions, fire or other casualty, and other causes beyond the reasonable
control of the party obligated to perform (collectively, the "Force Majeure"),
except with respect to the obligations imposed with regard to Rent and other
charges to be paid by Tenant pursuant to this Lease, shall excuse the
performance of such party for a period equal to any such prevention, delay or
stoppage and, therefore, if this Lease specifies a time period for performance
of an obligation of either party, that time period shall be extended by the
period of any delay in such party's performance caused by a Force Majeure.

     29.14  Notices.  All notices, demands, statements, approvals or

                 -------------
attempted to be made. If Tenant is notified of the identity and address of
Landlord's mortgagee or ground or underlying lessor, Tenant shall give to such
mortgagee or ground or underlying lessor written notice of any default by
Landlord under the terms of this Lease by registered or certified mail, and such
mortgagee or ground or underlying lessor shall be given the same opportunity to
cure such default as is afforded to Landlord prior to Tenant's exercising any
remedy available to Tenant.

     29.15  Joint and Several.  If there is more than one Tenant, the
            -----------------

Tenant shall not be entitled to make any repairs or perform any acts hereunder

hereunder against Landlord except as specifically provided herein; provided,
however, that the foregoing shall in no way impair the right of Tenant to

provisions hereof so long as notice is first given to Landlord and any holder of
a mortgage or deed of trust covering the Building, Project or any portion
thereof, of whose address Tenant has theretofore been notified, and an
opportunity is granted to Landlord and such holder to correct such violations as
provided above pursuant to Section 19.6.

     29.24  Landlord Renovations.  It is specifically understood and agreed that
            --------------------                                                
Landlord has no obligation and has made no promises to alter, remodel, improve,
renovate, repair or decorate the Premises, Building, Project or any part thereof
and that no representations respecting the condition of the Premises, the
Building or the Project have been made by Landlord to Tenant except as
specifically set forth herein or in the Tenant Work Letter. However, Tenant
acknowledges that Landlord may during the Lease Term renovate, improve, alter,
or modify (collectively, the "Renovations") the Building, Premises, and/or
Project, including without limitation the parking structure, Common Areas,
systems and equipment, roof, and structural portions of the same. Landlord
agrees to use Landlord's commercially reasonable efforts to minimize disruption
of Tenant's access to and use of the Premises and the parking facilities in
connection with any such Renovations. If Tenant is prevented from operating in
the Premises for more than one (1) business day because of any such Renovation,
there shall be an equitable abatement of Rent for the duration of the
interference. Landlord agrees to give Tenant prior written notice of any
Renovation which will materially interfere with Tenant's use of the Premises or
the parking facilities. Landlord shall have no responsibility or for any reason
be liable to Tenant for any direct or indirect injury to or interference with
Tenant's business arising from the Renovations, nor shall Tenant be entitled to
any compensation or damages from Landlord for loss of the use of the whole or
any part of the Premises or of Tenant's personal property or improvements
resulting from the Renovations or Landlord's actions in connection with such
Renovations, or for any inconvenience or annoyance occasioned by such
Renovations or Landlord's actions in connection with such Renovations.

following disclosure statement of the City of Newport Beach's policy regarding
John Wayne (Orange County) Airport is required to be included in all leases and
sub-leases for space in the Project.  Accordingly, Tenant agrees to include such
disclosure statement in any sublease of the Premises or any portion thereof, and
Tenant, as well as Tenant's heirs, successors and assigns, acknowledges that:

          (i)    John Wayne Airport may not be able to  provide adequate air
service for business establishments which rely on such service;

          (ii)   When an alternate air facility is  available, a complete phase
out of jet service may occur at John Wayne Airport; and

                                       44

commercial air service expansions at John Wayne Airport.

Maria Drive (i.e., the private road running along the easterly line of the
Project and presently connecting San Clemente Drive with Newport Center Drive)
for the purpose of ingress to and egress from the Project and said private road
serves both the Project and owner ("Owner") of the private road (i.e., the
Owner's building and the surrounding landscaped area and parking area).  The
Owner possesses the right to dedicate all or any portion of said road to the
City of Newport Beach at any time.  Additionally, the Owner possesses the right
to transfer and assign (to any buyer or ground lessee of its property) its non-
exclusive right to use said private road, or to enter into cross-easements with
any such buyer or ground lessee in connection with Landlord's non-exclusive
right to use said private road.  No exercise by Owner of any of its rights under
this Article shall have any effect upon this Lease, nor shall same subject
Landlord to any liability, as long as Tenant (along with its agents, employees
and invitees) continues to have the non-exclusive right to use said private road
with no material adverse effect thereon.  Santa Maria Drive (i.e., the private
road running along the easterly line of the Project) is not part of the Common
Areas, but Tenant (along with its agents, employees and invitees) shall have the
non-exclusive right to use said private road, as more specifically provided in
this Section 29.26.  Accordingly, all costs of repair and maintenance in
     -------------                                                      
connection with the entire private road (i.e., from Newport Center Drive to San
Clemente Street) shall be allocated proportionately as follows:  56% to the
Owner's facility (and thus not included as operating costs of the Project) and
44% to the Project (and thus included as Project Expenses of the Project.

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


  Tenant shall faithfully observe and comply with the following Rules and
Regulations.  Landlord shall not be responsible to Tenant for the nonperformance
of any of said Rules and Regulations by or otherwise with respect to the acts or
omissions of any other tenants or occupants of the Project.  Landlord shall,
however, use reasonable efforts to apply such Rules and Regulations in a non-
discriminatory manner against Tenant and the other tenants of the Project.

  1.  Tenant shall not alter any lock or install any new or additional locks or
bolts on any external doors of the Building or windows of the Premises without
obtaining Landlord's prior written consent and the locks to such exterior doors
shall be keyed to the Building's master key(s).  Tenant shall bear the cost of
any lock changes or repairs required by Tenant.  Two keys will be furnished by
Landlord for the Premises, and any additional keys required by Tenant must be
obtained from Landlord at a reasonable cost to be established by Landlord.

  2.  All doors opening to public corridors shall be kept closed at all times
except for normal ingress and egress to the Premises.

  3.  Landlord reserves the right to close and keep locked all entrance and exit
doors of the Building during such hours as are customary for comparable
buildings in the greater Newport Beach area.  Tenant, its employees and agents
must be sure that the doors to the Building are securely closed and locked when
leaving the Premises if it is after the normal hours of business for the
Building.  Any tenant, its employees, agents or any other persons entering or
leaving the Building at any time when it is so locked, or any time when it is
considered to be after normal business hours for the Building, may be required
to sign the Building register.  Access to the Building may be refused unless the
person seeking access has proper identification or has a previously arranged
pass for access to the Building.  Landlord shall reasonably cooperate in issuing
passes as reasonably requested by Tenant.  Landlord and his agents shall in no
case be liable for damages for any error with regard to the admission to or
exclusion from the Building of any person.  In case of invasion, mob, riot,
public excitement, or other commotion, Landlord reserves the right to prevent
access to the Building or the Project during the continuance thereof by any

construction work contemplated hereunder shall generally consist of
refurbishment of such existing tenant improvements and construction of new
tenant improvements in the Must-Take Space not heretofore leased by Tenant or an
Affiliate of Tenant.  This Tenant Work Letter is essentially organized
chronologically and addresses the issues of the construction of the Premises, in
sequence, as such issues will arise during the actual construction of the
Premises.  All references in this Tenant Work Letter to Articles or Sections of
"this Lease" shall mean the relevant portion of Articles 1 through 29 of the

Space II is the aggregate amount of Nine Hundred Seventy-Eight Thousand One
Hundred Ninety Dollars ($978,190).  In no event shall Landlord be obligated to

calculating the amount of the Tenant Improvement Allowance. Except with respect
to the portion of the Tenant Improvement Allowance allocable to Must-Take Space
II, any portion of the Tenant Improvement Allowance which is not utilized by
Tenant by December 31, 1998 (or the date twelve (12) months after the applicable
Must-Take Space Rent Commencement Date with respect to Suites 100 and 150 of
Must-Take Space II), shall revert to Landlord and Tenant shall receive no credit
for any unused portion of the Tenant Improvement Allowance. All Tenant
Improvements for which the Tenant Improvement Allowance has been made available
