                                     PART I


Item 1.          Business

         General

         United Asset Management Corporation (UAM or the Company) is a holding
company organized in December 1980 to acquire and own firms that provide
investment advisory services primarily for institutional clients. The Company's
wholly owned subsidiaries (Affiliated Firms or Firms) operate in one business
segment, that is, as investment advisers, managing both domestic and
international investment portfolios for corporate, government and union benefit
plans, mutual funds, individuals, endowments, and foundations. UAM intends to
continue expanding through the internal growth of its present Affiliated Firms
and through the acquisition or organization of additional firms in the future
(see "Affiliated Firms"). In addition, UAM plans to continue to diversify,
domestically and internationally, with respect to both the classes of assets
managed and client base. While UAM's Affiliated Firms primarily specialize in
the management of U.S. equities, bonds and cash, other asset classes under
management include international securities, real estate and stable value
assets.

         Advisory fees based on the assets of pension plans, profit sharing
plans, endowments and foundations provide the largest portion of the Company's
revenues. Such clients are sometimes referred to as "institutional" clients, and
they are generally "tax-exempt" in that the income and any capital gains which
result from their portfolio investments are not taxable to them under present
law. Advisory fees are primarily based on the value of assets under management.
Fee rates typically decline as account size increases. The assets of
institutional clients have generally been growing, with the most rapid growth
achieved by pension and profit sharing plans (sometimes called employee benefit
plans). For the year ended December 31, 1998, no single client of any Affiliated
Firm provided more than 4% of the Company's consolidated revenues. Accordingly,
the loss of any single client would not have a material adverse effect on the
Company's total investment management business.

         Each Affiliated Firm operates under its own name, with its own
investment philosophy and approach. Each conducts its own investment analysis,
portfolio selection, marketing and client service. During any given period,
investment results may vary among Firms. Client fees are set by each Firm based
on its own judgment concerning the market for the services it renders. Each Firm
is separately regulated under applicable federal, state or foreign law.

         In addition to the Firms' individual efforts, UAM has established
distribution and client service organizations which are available to the
Affiliated Firms to supplement the investment management services they provide.
UAM has also developed an operating partnership concept with the Affiliated
Firms. These are described more fully under "Method of Operation."

         UAM has revenue sharing plans with the Affiliated Firms which are
described more fully under "Revenue Sharing." These agreements provide for UAM
to receive increased or decreased revenues from each Affiliated Firm, based on a
percentage of the change in each Firm's revenues from year to year, starting
from a base amount agreed upon in the year of acquisition or at inception. These
arrangements allow each Firm to set its own operating expense budget and
compensation practices, limited by the share of revenues available to the Firm.

         The Industry

         Revenues in the institutional investment management industry are
determined primarily by fees based on assets under management. Therefore, the
principal determinant of growth in the industry is the growth of institutional
assets under management. In management's judgment, the major factors which
influence changes in institutional assets under management are: (a) changes in
the market value of securities; (b) net cash flow into or out of existing
accounts; (c) gains of new or losses of existing accounts by specific firms or
segments of the industry; and (d) the introduction of new products by the
industry or by particular firms.

         In general, assets under management in the institutional segments of
the industry have increased steadily. For example, Money Market Directories,
Inc. recorded in its 1999 Directory $5.8 trillion in assets under management in
accounts of employee benefit plans and endowments within the United States as of
mid-1998, which represents an average compound five-year annual growth rate of
13.5% since mid-1993. The 1999 Directory also reported $12.1 trillion of assets
under management as of mid-1998 at investment advisory firms (including branch
offices) within the United States, which represents an average compound
five-year annual growth rate of 21.7% over the corresponding assets since
mid-1993.

         The employee benefit plan market includes two principal sectors:
defined benefit and defined contribution plans. More than half of U.S.
retirement plan assets are in defined benefit plans, which assure employees of a
particular level of pension benefits when they retire. The Employee Retirement
Income Security Act of 1974 (ERISA) and the Internal Revenue Code of 1986 (the
Code) require employers to fund their defined benefit plans sufficiently to
generate the benefits they have promised. However, the Code also discourages
overfunding of defined benefit plans by employers by limiting tax deductions for
contributions to fully funded plans. In management's opinion, high investment
returns experienced in the 1990s have resulted in many defined benefit
retirement plans reaching or exceeding their full funding limits based on
actuarial calculations; therefore, many employers have ceased to contribute
additional cash to the plans. However, if the value of plan assets declines due
to market factors, or if sustained periods of low interest rates cause an
increase in the actuarial value of plan liabilities, employers will generally be
obligated to step up contributions to their defined benefit pension plans. This
counter-cyclical funding pattern for defined benefit plans helps to smooth out
fluctuations in the growth of plan assets under management by firms that provide
investment advisory services to sponsors of defined benefit plans, and
therefore, it helps to moderate fluctuations in the revenues of these investment
managers. Under defined contribution plans, on the other hand, employers may
contribute to their employees' retirement funds on a tax-advantaged basis, but
individual employees generally decide how their plan assets will be invested.
Defined contribution plans are the fastest growing sector of the employee
benefit plan market.

         Competition

         The Affiliated Firms compete to manage domestic and international
investment portfolios for corporate, government and union benefit plans, mutual
funds, individuals, endowments, and foundations. Management believes that the
most important factors affecting competition in the investment management
industry are: (1) the abilities and reputations of investment managers; (2)
stability of a firm's workforce, especially of portfolio managers; (3) an
effective marketing force 


                                       2

<PAGE>

with broad access to channels of distribution; (4) differences in the investment
performance of investment management firms; (5) adherence to particular
investment styles; (6) quality of client service; (7) the development of new
investment strategies; (8) resources to invest in information technologies; and
(9) public recognition of trade names in retail markets.

         The Affiliated Firms face many competitors, including public and
private investment advisers, as well as affiliates of securities broker-dealers,
commercial banks, investment banks, and insurance companies. Barriers to entry
are low, and firms in the investment management business are relatively
long-lived.

         Institutional clients typically may terminate investment management
contracts without penalty upon 30-days' notice. Mutual funds typically may
terminate investment management contracts without penalty upon 60-days' notice,
and retail clients may redeem investments in mutual funds at any time.

         Method of Operation

         UAM itself does not manage portfolio investments for clients and does
not provide any investment advisory services to Affiliated Firms and therefore
is not registered as an investment adviser under federal, state or foreign law.
UAM respects the individual character of each Affiliated Firm and seeks to
preserve an environment in which each Firm continues to provide investment
management services which meet the particular needs of the Firm's clients. UAM
provides assistance to the Affiliated Firms in connection with the preparation
of separate company financial statements, tax matters, insurance and maintenance
of a company-wide profit sharing retirement plan. As part of its operating
partnership with its Affiliated Firms, UAM provides support through a series of
marketing and service organizations, and invests with its Firms in areas such as
distribution, new product development, and enhanced marketing and client service
efforts. In addition to promoting this operating partnership, UAM's Operations
Group assists Firms in planning for future growth and management development,
particularly with respect to succession planning. The Company also sponsors
seminars and meetings for executives from each of the Affiliated Firms and from
UAM which serve as forums for sharing business information.

         During 1998, the Company expanded its website www.uam.com with new
features including in-depth information on the UAM Funds for individual
investors, an area providing specialized information for financial advisors,
descriptions of the Affiliated Firms with links to their websites, and broader
information on the Company itself. The Company expects this site will play a
major role in its marketing and communication efforts.

         In recent years, UAM has established a number of organizations that
augment the marketing and client service capabilities of its Affiliated Firms.

         UAM (Japan) Inc. offers the diverse investment management services of
the Affiliated Firms to the Japanese institutional market. UAM (Japan) has a
license to offer fully discretionary investment management services to Japanese
institutional investors.

         UAM Investment Services, Inc. provides multi-product and global
capabilities to financial advisors and major financial institutions in the
United States and Europe. It provides a single 


                                       3

<PAGE>

convenient channel through which clients can utilize the many investment
management products offered by the Affiliated Firms.

         UAM Funds, Inc., a series mutual fund, allows Affiliated Firms to open
portfolios to pool client accounts in an efficient, cost-effective manner and to
provide additional investment styles. As of December 31, 1998, 23 of the
Affiliated Firms managed 46 UAM Funds portfolios, and such portfolios held
assets totaling $3.5 billion.

         UAM Fund Services, Inc. oversees service providers used by UAM Funds,
Inc. and, upon request, by separate fund families offered by Affiliated Firms.

         UAM Trust Company assists Affiliated Firms in establishing commingled
investment pools for their clients. Collective group trusts and other commingled
investment vehicles can fit those situations where neither separately managed
accounts nor mutual funds meet clients' needs.

         UAM Shareholder Service Center, Inc. provides telephone servicing and
transfer agent support to UAM mutual fund groups. The center enables Pilgrim
Baxter and other UAM Affiliated Firms to consolidate and enhance shareholder
services and marketing activities.


         UAM believes that the professional independence of the Affiliated Firms
and the continuing diversification of investment philosophies and approaches
within the Company are necessary ingredients of UAM's success and that of the
Affiliated Firms. Most key employees of each Affiliated Firm at the time of
acquisition by UAM have continued with their Firm in accordance with employment
agreements executed in connection with each acquisition, have remained on their
Firm's Board of Directors, and have continued to serve as its executive
officers. Each Affiliated Firm's directors and officers are responsible for
reviewing their respective Firm's results, plans and budgets.

         See Note 7 of the Annual Report, which is incorporated herein by
reference, for the Company's segment information.

         Revenue Sharing

         Most of UAM's Affiliated Firms operate under revenue sharing plans.
Such plans permit each Firm to retain a specified percentage of its revenues
(typically 50-70%) for use by its principals at their discretion in paying
expenses of operations, including salaries and bonuses. The purposes of the
plans are to provide significant ongoing incentives for the principals of the
Affiliated Firms to continue working as they did prior to the sale of their firm
to UAM, to support their autonomy, and to allow UAM to participate in the growth
of revenues of each Affiliated Firm. The plans are designed to allow each Firm's
principals to participate in that Firm's growth in a substantial manner and to
make operating decisions freely within the limits of that portion of the Firm's
revenues which is retained by the Firm. In effect, the portion of its revenues
retained by each Firm that is not used to pay salaries and other operating
expenses is available for payment to the principals and other key employees of
such Firm in the form of bonuses. The portion of Affiliated Firm revenues
retained by the Firms and used to pay salaries and bonuses and to fund operating
expenses is included in the Company's Consolidated Statement of Operations.


                                       4

<PAGE>

         Under each agreement, when an Affiliated Firm is acquired by UAM, the
base revenues of the Firm are established, and a share of such revenues is
allocated to UAM, with the balance being the acquired Firm's share of revenues.
In addition, agreement is reached on the Firm's and UAM's respective percentage
shares of changes in such Firm's revenues compared to its base revenues. The
Affiliated Firm pays for all of its business expenses out of its share of
revenues. Each year, the amount of the Affiliated Firm's revenues that is paid
to UAM and the amount that is retained by the Firm are adjusted upwards in the
case of growth in such Firm's revenues over its base, or downwards in the case
of decreases in such Firm's revenues below its base, by applying the agreed-upon
percentages to the total increase or decrease in the Firm's revenues. Under most
of the existing revenue sharing agreements, UAM's share of increases above a
Firm's base revenues is between 30% and 50%, and UAM's share of decreases below
a Firm's base revenues is between 50% and 70%. Thus, in any year in which the
Affiliated Firm's revenues increase over its base revenues, the Firm retains a
portion of such additional amounts to use as its principals may decide. The
balance of the increase in the Affiliated Firm's revenues is paid to UAM, in
addition to UAM's share of such Firm's base revenues. In any year in which the
Affiliated Firm's revenues decrease to a level below its base revenues, the
Firm's share of its base revenues is reduced by the Firm's portion of the
decrease, and therefore, the Firm may need to reduce its expenses. Similarly,
the revenue sharing amount paid to UAM will be reduced by UAM's share of any
decline in the Affiliated Firm's revenues below its base.

         In addition to revenue sharing with its Affiliated Firms, UAM has
designed incentive programs to further reward business growth through positive
net client cash flow. Incentives awarded under these programs are paid in the
combination of cash, stock options and incentive units.

         Affiliated Firms

         Each Affiliated Firm conducts its own marketing, client relations,
research, portfolio management and administrative functions. Each Firm sets its
own investment advisory fees and manages its business independently on a
day-to-day basis.

         The investment philosophy, style and approach of each Affiliated Firm
are independently determined by it, and these philosophies, styles and
approaches may vary substantially from firm to firm. As a consequence, more than
one Affiliated Firm may be retained by a single client, since many clients
employ multiple investment advisers. The strategies employed and assets selected
by Affiliated Firms are separately chosen by them, with the result that any one
Firm may be bullish on the stock or bond market while another Firm is bearish.
Two of the Affiliated Firms are full-service institutional real estate
investment management firms with $9.8 billion of assets under management at year
end. These Firms invest in real estate properties in the U.S. and overseas for
their U.S. and foreign clients and provide a broad spectrum of real estate
services, including research, acquisition and disposition, financing, and asset
and property management. Another Affiliated Firm, with $10.3 billion of assets
under management at year end, manages stable value asset portfolios such as
guaranteed investment contracts (GICs) and synthetic GICs.

         All of these differences, when combined with the separate names and
identities of the various Affiliated Firms may: (1) tend to insulate UAM from
the various cycles of market performance for specific asset classes and
individual Firms; (2) permit more than one Affiliated 


                                       5

<PAGE>

Firm to serve any single client; and (3) mean that some Affiliated Firms may
attract substantial new business while other Firms may grow more slowly or lose
business.

         UAM's Firms manage both domestic and international investment
portfolios for corporate, government and union benefit plans, mutual funds,
individuals, endowments, and foundations. As of December 31, 1998, UAM's Firms
had approximately $201.4 billion under management with an average account size
of $32.3 million. The 20 largest clients of UAM's Affiliated Firms represented
16% of total revenues and the 100 largest clients represented 28%. Additional
information regarding the number of clients and types and amounts of assets
under management is found in the table on page 36 of the Annual Report.


The following table summarizes UAM's asset mix:

         As previously described, each Affiliated Firm is responsible for
marketing its own investment management services. Typically, one or more of the
employees at each Firm are responsible for making initial contact with
prospective clients. Most Firms have brochures describing the Firm, its
principals and its investment approach. These brochures are mailed to
prospective clients, in addition to soliciting clients by telephone and in
person. Once initial contact is made, face-to-face meetings between the
principals of a Firm and the prospective client take place to discuss investment
philosophy, management fees and a variety of other related matters.

         UAM's Acquisition Program

         Since its inception, UAM has sought to acquire or to establish
institutional investment management firms. Once it acquires or organizes such
firms, UAM seeks to preserve their autonomy by allowing their key employees to
retain control of investment decisions and manage day-to-day operations, while
adding value to the Firm through an operating partnership described below. When
an Affiliated Firm is acquired from employee-stockholders, the former
stockholders receive the added benefits of a more diversified company by virtue
of equity ownership in UAM. After acquisition by UAM, Affiliated Firms continue
to operate under their own firm name, with their own leadership and individual
investment philosophy and approach.

         In selecting acquisition candidates, the Company seeks investment
management firms that will enhance the business of existing affiliates, provide
entry to new channels of distribution, or boost UAM's participation in
attractive asset classes that are currently under-represented among its firms.
UAM is interested in companies that have pursued their investment philosophy
with consistency, shown a determination and an ability to grow, and developed a
second generation of 


                                       6

<PAGE>

money managers and leaders. In addition, UAM has acquired or organized firms at
various stages of development, from start-up to relatively mature firms and has
acquired both employee-owned firms and subsidiaries or divisions of financial
institutions.

         UAM has observed that the major reasons that employee-owned firms
consider selling to UAM include: (1) the high value of the firm relative to its
principals' total net worth; (2) the need for liquidity on the part of the
principals; (3) their desire for diversification and a reduction in their
exposure to a single firm's results; (4) their autonomy after acquisition; and
(5) increasingly, the access to channels of distribution provided by UAM's
service firms. Substantially all the key employees of Affiliated Firms continue
to be actively involved in their firms long after their acquisition by UAM.

         In purchasing investment management firms, UAM has structured the
transactions to create incentives for key personnel to remain with their firm
after the expiration of their employment agreements. The key employees have
entered into employment and noncompete agreements for terms ranging primarily
from five to 12 years, which also prohibit the employees from competing with
their firm for a substantial period after termination of employment. Most of the
key employees of the Affiliated Firms were stockholders of such firms prior to
their acquisition by UAM. In connection with the purchases, the former
stockholders and/or key employees have typically received consideration in the
form of cash, subordinated notes and warrants to purchase UAM common stock, or
UAM common stock. The subordinated notes, most of which may be used to exercise
the warrants, generally have terms of between five and 10 years. The key
employees of each Affiliated Firm also participate directly, through revenue
sharing, in revenues of their firm and meet the firm's expenses from their share
of these revenues, as described more fully under "Revenue Sharing."


         To fund acquisitions, the Company utilizes its existing capital,
together with Operating Cash Flow (net income plus amortization and
depreciation) and borrowings available under its $750,000,000 Reducing Revolving
Credit Agreement (as more fully described in Note 3 of the Company's 1998 Annual
Report to Stockholders (the Annual Report); also see Items 8 and 14 of this Form
10-K). Such borrowings are secured by the stock of the Company's subsidiaries.

         Regulation

         UAM's domestic investment advisory subsidiaries are registered with and
subject to regulation by the Securities and Exchange Commission (the SEC) under
the Investment Advisers Act of 1940 and, where applicable, under state advisory
laws. The Company's foreign investment advisory affiliates are members of or
subject to certain self-regulatory bodies or other regulatory agencies. The
Company's brokerage subsidiaries are registered as broker-dealers with the SEC
under the Securities Exchange Act of 1934 and, where applicable, under state

Item 7A.         Quantitative and Qualitative Disclosures About Market Risk

          The Company's primary market risk exposures are in the areas of
interest-rate risk, foreign currency exchange-rate risk, and equity-price risk.

The Company's exposure to interest-rate risk arises from variable-rate and
fixed-rate debt arrangements entered into for other-than-trading purposes. To
mitigate the risks associated with increases in interest rates, the Company has
entered into and plans to continue to enter into interest-rate protection
agreements. The agreements outstanding as of December 31, 1998 extend up to
three years and limit interest rates to an average of 8.5%. Tabular information
with respect to these interest-rate protection agreements has not been presented
as the financial statement impact of such agreements is not considered material.

The table below summarizes the Company's market risks associated with debt
obligations as of December 31, 1998. The Company had $287,000,000 outstanding
under its $750,000,000 Reducing Revolving Credit Agreement (the Credit
Agreement) as of December 31, 1998. Interest rates available for amounts
outstanding under the Credit Agreement are currently: prime, 1.5% over LIBOR or
a money market bid option. The recorded cost of the Senior Notes and Credit
Agreement approximates fair value. Due to the unique nature of each of the
subordinated debt instruments issued as consideration for businesses acquired,
an assessment of current fair value is not practicable. Effective interest rates
shown in the table for subordinated debt instruments is a weighted-average of
fixed interest rates attaching to notes having the particular expected year of
maturity. The Company intends to finance subordinated debt that becomes due
which has not been tendered in connection with the exercise of warrants by
utilizing its Credit Agreement. As such, the $10,657,000 of subordinated notes
due in 1999 have been included in the payments due in 2003, the year the line of
credit expires.

The Company also has exposure to foreign currency exchange-rate fluctuations for
the cash flows received from its foreign affiliates. This risk is mitigated by
the fact that the operations of its subsidiaries, most of which are located in
the U.K. or Canada, are conducted in their respective local currencies. In
addition, any cash remitted by the foreign affiliates occurs shortly after the
related accounts receivable have been collected, further mitigating this risk.
Currently, the Company does not engage in foreign currency hedging activities as
it does not believe that its foreign currency exchange rate risk is material.

The Company also has equity-price risk as more fully described in the "Industry"
section on page two. This risk is somewhat mitigated by the Company's practice
of participating in revenue sharing with its affiliates. See page four for a
discussion of "Revenue Sharing." The Company does not use any market-rate
sensitive instruments for trading purposes or otherwise to protect against this
risk.

To the Board of Directors
of United Asset Management Corporation


Our audits of the consolidated financial statements referred to in our report
dated February 3, 1999 appearing on page 58 of the 1998 Annual Report to
Stockholders of United Asset Management Corporation (which report and
consolidated financial statements are incorporated by reference in this Annual
Report on Form 10-K) also included an audit of the Financial Statement Schedule
listed in Item 14(a) of this Form 10-K. In our opinion, this Financial Statement
Schedule presents fairly, in all material respects, the information set forth
therein when read in conjunction with the related consolidated financial
statements.
