                                     PART I

ITEM 1.    BUSINESS

Flowserve Corporation ("Flowserve") was incorporated under the laws of the State
of New York on May 1, 1912. On July 22, 1997, Flowserve (formerly known as Durco
International Inc. and The Duriron Company, Inc.) merged with BW/IP, Inc.
("BW/IP") in a stock-for-stock merger of equals, accounted for as a pooling of
interests, (hereafter the "Merger"). The Merger created one of the world's
leading providers of industrial flow management services. All references herein
to the "Company" or "Flowserve" refer collectively to Flowserve and its
subsidiaries unless otherwise indicated by the context.

Flowserve is principally engaged in the design, manufacture, distribution and
service of industrial flow management equipment throughout the world. The
Company provides pumps, valves and mechanical seals primarily for the refinery
and pipeline segments of the petroleum industry, the chemical processing
industry, the power generation industry and other industries requiring flow
management products and services. Flowserve manufactures certain standard
products, but specializes in the development of precision engineered equipment
for critical service applications where high reliability is required. The
Company's materials expertise, design and engineering capabilities and
applications know-how have enabled it to develop product lines that are
responsive to customers needs for manufacturing efficiency, reduced maintenance
cost, and avoidance of premature equipment failure.

An important element of Flowserve's business is its successful emphasis on
providing aftermarket products and services. These consist of supplying parts,
making repairs and providing a variety of technical services for the upgrade or
retrofit of equipment to extend its useful life or improve its operating
characteristics.

The Company operates in three business segments: Rotating Equipment, Flow
Control and Flow Solutions. Included in Note 12 to the consolidated financial
statements on pages 35 through 38 of the 1998 Annual Report to Shareholders,
provided as part of Item 8 of this Form 10-K and incorporated herein by
reference, is information concerning the Company's sales, operating income and
identifiable assets by business and geographic segment for each year in the
three-year period ended December 31, 1998. For a significant portion of its
products, the Company's domestic operations supply each other and the Company's
foreign manufacturing subsidiaries with components and subassemblies.

ROTATING EQUIPMENT 

PRODUCTS

Through its Rotating Equipment Division business segment, the Company designs,
manufactures and distributes pumps and related equipment. Pump products
accounted for approximately 34.0%, 35.0% and 36.1% of the Company's sales to
external customers in 1998, 1997 and 1996, respectively. Pumps are manufactured
to industry-recognized standards, including those set by the American Petroleum
Institute (API), the American National Standards Institute (ANSI) and the
International Standards Organization (ISO).

Pump products for the petroleum industry include horizontal double case pumps
used especially for hot oils under high pressure, horizontal multi-stage pumps
used in pipelines, vertical pumps used for low specific gravity applications,
vertical circulating pumps used for cooling water, submersible pumps used for
water or brine injection in oil fields, and submersible water pumps used on
offshore platforms to supply water for fire fighting.


                                       1
<PAGE>   3



Pump products for chemical processing industries include metallic and
nonmetallic pumps, varying in size, capacity, material components and sealant
specifications. These pumps are used primarily to move liquids during processing
activities, but also in auxiliary services such as waste removal, water
treatment and pollution control. The pumps are modular in design and
manufactured to withstand the abrasive and/or corrosive service fluids being
processed by customers in these industries.

Pump products for the power generating industry include a variety of pumps used
in both nuclear and fossil fuel facilities to generate steam. Products for the
fossil fuel power generation industry are horizontal double case pumps for high
pressure boiler feed applications, horizontal multi-stage pumps for low pressure
boiler feed applications, vertical double case pumps and vertical circulating
pumps.

The Company supplies pumps for other industrial uses, including without
limitation industrial production, utility services, pollution control, mining
operations and municipal water transport.

MARKETING AND DISTRIBUTION

Pumps or pump components are produced in plant facilities in the United States
(one in California, one in Oklahoma, one in Ohio, two in New Mexico), Mexico,
Argentina, Belgium and two in The Netherlands. Pump manufacturing facilities in
The Netherlands and Belgium are key sources of pumps sold in Europe, Africa and
the Middle East. The Argentine facility provides products primarily for
Argentine customers, but also serves customers in other South American
countries. The Company's Mexican operation manufactures pumps for export and for
Mexican customers. Large vertical circulating pumps manufactured in Mexico are
distributed worldwide. A majority-owned joint venture in India, which began
production in late 1997, manufactures ANSI and ISO pump components which are
assembled in Belgium.

The two specialized component manufacturing facilities in New Mexico provide a
significant portion of pump components (except for ANSI pump components). The
component facilities also supply components to other Company plants outside of
the U.S. on an economically selective basis.

The Company's pump products are primarily marketed to end-users and engineering
contractors through the Company's worldwide pump sales force, regional service
centers, independent distributors and representatives and, for modular pumps, a
national parts distribution center.

The majority of the Company's sales of pump products in the nuclear power market
are in the United States and Japan, where the Company's large installed base of
equipment provides a continuing market for products and services to ensure
safety and reliability, major customer concerns. A significant characteristic of
the nuclear market worldwide is the stringent requirements that must be met in
order to sell products to nuclear power plants. For example, the Company
maintains a Nuclear Stamp ("N Stamp") from the American Society of Mechanical
Engineers, which is required for qualification to supply certain kinds of
products to the U.S. nuclear industry.

The Company could face liability in excess of its own commercial or government
provided insurance if any of its products were found to contribute to an
accident at a nuclear power facility or at other industrial facilities. The
Company does not maintain nuclear liability insurance for the United States or
Canada, but maintains an aggregate of $15 million in nuclear liability insurance
for all other countries. The Federal Price-Anderson Act of 1954 provides U.S.
nuclear utilities with a system of no-fault insurance coverage in an amount up
to about $8.7 billion for third party losses or damages resulting from a nuclear
incident.

BACKLOG

The Rotating Equipment Division's backlog of orders at December 31, 1998, was
$162.7 million, compared to $169.4 million at December 31, 1997. The Company
believes that a very high percentage of the current backlog will be shipped by
December 31, 1999.

FLOW CONTROL 

PRODUCTS

Through its Flow Control Division business segment, the Company designs,
manufactures and distributes quarter-turn manual valves, automatic control
valves, actuators, and related components. Valve products accounted for
approximately 27.3%, 26.5% and 25.0% of the Company's sales to external
customers in 1998, 1997 and 1996, respectively. Valves are used to control the
flow of liquids and gases. Valve products for industrial processing systems
include plug and butterfly valves made of various metals, alloys and plastics
and lined ball valves. Actuators and other control accessories manufactured by
the Company are either sold independently or mounted on valves to move them from
open to closed positions and to various specified positions in between. Valve
products for the nuclear power market include a complete line of gate, globe and
check valves (including valve actuators). Automatic control valves include high
pressure valves, rotary valves, and anti-noise and anti-cavitation valves. These
valves are generally sold with an actuator. "Smart" valve technologies have been
incorporated into various control valve products to provide more efficient
process control. Through a technology alliance with Honeywell Inc., a
manufacturer of computerized control systems and software for process plants,
the Company's "smart" and control valve technologies are being incorporated in
Honeywell's distributed control systems.

MARKETING AND DISTRIBUTION

Valves are produced at facilities in the United States (two in Utah, one in
Pennsylvania, and one in Tennessee), Australia, France, Germany (one in Ahaus,
one in Essen) and Switzerland. Actuators are produced at facilities in the
United States (Utah and Ohio), Germany, France, and Italy. Two Company
majority-owned joint ventures in India (which began production in late 1997)
manufacture valves for export to U.S., Asian and European markets. In 1998 the
Company acquired Valtek Engineering Division of Rolls Royce plc, a former
licensee with territorial rights covering certain Company control valves in
parts of Europe, the Middle East and Africa.

Manual valve products and valve actuators are distributed through the Company's
sales personnel and through a network of independent stocking distributors.
Automatic control valves are marketed through specialized sales offices with
engineers and service centers or on a commission basis through independent
manufacturing representatives in principal marketing centers throughout the
United States and other countries.

BACKLOG

The Flow Control Division's backlog of orders at December 31, 1998 was $69.8
million, compared to $67.0 million at December 31, 1997. The Company believes
that virtually all of the current backlog will be shipped by December 31, 1999.

FLOW SOLUTIONS 

PRODUCTS

Through its Flow Solutions Division business segment, the Company designs,
manufactures and distributes mechanical seals and sealing systems and provides
service and repair for flow control equipment used in 


                                       3
<PAGE>   5


process industries. Mechanical seal products and flow management services and
repairs accounted for approximately 38.7%, 36.0% and 36.9% of the Company's
sales to external customers in 1998, 1997 and 1996, respectively.

The mechanical seal is critical to the smooth operation of centrifugal pumps,
compressors and mixers because mechanical seals help prevent leakage between a
rotating shaft and a stationary casing. In doing so, mechanical seals reduce
shaft wear on pumps, compressors and mixers used in many industries. The
Company's seals are used on a variety of pumps, mixers, compressors, steam
turbines and specialty equipment, principally in the oil refining and chemical
processing industries. The Company also manufactures a dry gas seal used in gas
transmission and oil and gas production markets. In 1998, the Company acquired
its former licensee's seal manufacturing and service business in Australia and
the remaining ownership interests in its seal manufacturing joint venture in
Singapore.

The Company has established a global network of service facilities throughout
the world which have the capability to provide service, repair and diagnostics
for rotating equipment, including pumps, turbines, mixers and compressors, as
well as numerous types of valves and mechanical seals. In 1998, the Company has
expanded its service network with the acquisition of two European valve repair
companies: ARS Loheren NV in Belgium and ZAR Beheer BV in The Netherlands, plus
the acquisition of the assets of a Canadian service repair facility. The Company
sees the opportunity to expand this service repair business, as many of its
customers look for alternatives to their own in-house maintenance capabilities
or to small and independent service facilities with limited expertise.

MARKETING AND DISTRIBUTION

Mechanical seals are primarily produced in facilities in the United States (one
in California, one in Michigan), The Netherlands, Germany, Mexico, Argentina,
Brazil, Singapore, New Zealand, Australia and Japan. Seal manufacturing
facilities in The Netherlands and Germany are key sources of seals sold in
Europe, Africa and the Middle East.

The Company's mechanical seal products are primarily marketed through the
Company's worldwide seals sales force directly to end users and engineering and
construction firms. A portion of the Company's seal products is sold directly to
original equipment ("OE") manufacturers for incorporation into pumps,
compressors, mixers or other rotary equipment requiring seals. Distributors,
dealers, commissioned representatives and sales agents are also used in the
distribution and sale of mechanical seal products.

Fully equipped service centers provide equipment maintenance, including major
repairs, advanced diagnostics, installation, commissioning, re-rate and retrofit
programs and full machining capabilities. A network of quick response centers
provides local engineering, manufacturing and assembly capabilities for
mechanical seals, as well as seal inventory.

BACKLOG

The Flow Solutions Division's backlog of orders at December 31, 1998, was $56.4
million compared to $54.4 million at December 31, 1997. The Company believes
that virtually all of the current backlog will be shipped by December 31, 1999.

GENERAL BUSINESS

COMPETITION

The markets for the Company's products are highly competitive. Competition
occurs on the basis of price, technical expertise, delivery, contractual terms,
previous installation history and reputation for quality.


                                       4
<PAGE>   6


Delivery speed and the proximity of service centers are important with respect
to aftermarket products. Customers are generally more likely to rely on the
Company than competitors for aftermarket products relating to its more highly
engineered and customized products than for its standard products. Price
competition tends to be more significant for OE manufacturers than aftermarket
services and has been generally increasing.

In the aftermarket portion of its service business, the Company competes against
both large and well-established national or global competitors and, in some
markets, against smaller regional and local companies, as well as the in-house
maintenance departments of the Company's end-user customers. In the sale of
aftermarket products and services, the Company benefits from the large installed
base of pumps which require maintenance, repair and replacement parts.

In the petroleum industry, the competitors for aftermarket services tend to be
the customers themselves because of their in-house capabilities. In other
industries, except the nuclear power industry, the competitors for aftermarket
services tend to be low cost replicators of spare parts and local independent
repair shops for the Company's products. The Company has certain competitive
advantages in the nuclear power industry because it maintains the N Stamp that
is required to service customers in that industry and because the Company has a
considerable base of proprietary knowledge.

 Customers for the Company's products are attempting to reduce the number of
vendors from which they purchase in order to reduce the size and diversity of
their inventory. Although vendor reduction programs could adversely affect the
Company's business, the Company has been successful in entering into "alliance"
arrangements with a number of customers both in the United States and overseas
which provide competitive advantages to the Company.

RESEARCH AND DEVELOPMENT

The Company conducts research and development at its own facilities in various
locations. In 1998, 1997, and 1996, the Company spent approximately $14.7
million, $14.8 million, and $13.9 million, respectively, on Company-sponsored
research and development, primarily for new product development and extensions.

The Company's research and development group consists of engineers involved in
new product development as well as the support and improvement of existing
products. Additionally, the Company sponsors consortium programs for research
with various universities and conducts limited development work jointly with
certain of its vendors, licensees and customers. Management believes current
expenditures are adequate to sustain ongoing research and development
activities.

CUSTOMERS

The Company sells to a wide variety of customers. No individual customer
accounted for more than 10% of the Company's 1998 net sales.

RISKS OF INTERNATIONAL BUSINESS

In 1998 42% of the Company's sales were outside the United States. The Company's
activities thus are subject to the customary risks of operating in an
international environment, such as unstable political situations, local laws,
the potential imposition of trade restrictions or tariff increases and the
relationship of the U.S. dollar to other currencies. The impact of these
conditions is mitigated somewhat by the strength and diversity of the Company's
product lines and geographic coverage. To minimize the impact of foreign
exchange rate movements on its operating results, the Company enters into
forward exchange contracts to hedge specific foreign currency denominated
transactions. See Note 1 to consolidated financial statements on pages 25 and 26
of the 1998 Annual Report to Shareholders, which is incorporated by reference in
this Form 10-K. The Company conducts substantial business activities in the
Middle East.


                                       5
<PAGE>   7


INTELLECTUAL PROPERTY

The Company owns a number of trademarks and patents relating to the name and
design of its products. The Company considers its trademarks Byron Jackson(R),
Durco(R), United Centrifugal(R), Durametallic(R), BW Seals(R), GASPAC(R),
Pacific Wietz(TM), Five Star Seal(R), Wilson-Snyder(R), Valtek(R), Kammer(R),
Sereg(TM) and Automax(R) to be important to its business. The patents underlying
much of the technology for the Company's products have been in the public domain
for many years. Surviving patents are not considered, either individually or in
the aggregate, to be material to the Company's business. However, the Company's
pool of proprietary information, consisting of know-how and trade secrets
relating to the design, manufacture and operation of its products and their use,
is considered particularly important and valuable. Accordingly the Company
protects such proprietary information. The Company, in general, is the owner of
the rights to the products which it manufactures and sells, and the Company is
not dependent in any material way upon any license or franchise to operate.

RAW MATERIALS

The principal raw materials used by the Company in the manufacture of its
products are normally readily available. While substantially all raw materials
are purchased from outside sources, the Company has been able to obtain an
adequate supply of raw materials, and no shortage of such materials is currently
anticipated. The Company intends to expand its use of worldwide sourcing to
capitalize on low cost sources of purchased goods.

The Company is a vertically-integrated manufacturer of certain pump and valve
products. Certain corrosion-resistant castings for Company pumps and
quarter-turn valves are manufactured at its Dayton, Ohio foundries; other metal
castings are purchased from outside sources.

The Company also produces most of its highly engineered corrosion resistant
plastic parts for certain pump and valve product lines. This includes
rotomolding as well as injection and compression molding of a variety of
fluorocarbon and other plastic materials.

Suppliers of raw materials for nuclear markets must be qualified by the American
Society of Mechanical Engineers and, accordingly, are limited in number.
However, the Company to date has experienced no significant difficulty in
obtaining such materials.

EMPLOYEES AND LABOR RELATIONS

The Company and its subsidiaries employ approximately 7,000 persons of whom
approximately 55% work in the United States. The Company's hourly employees at
its three principal U.S. pump manufacturing plants in Vernon, California,
Dayton, Ohio, and Tulsa, Oklahoma, plus those at its valve manufacturing plant
in Williamsport, Pennsylvania and at its foundries in Dayton, Ohio are
represented by unions. The Company's operations in Mexico, The Netherlands,
Germany and Belgium are unionized. The Company believes employee relations
throughout its operations are satisfactory, including those represented by
unions.

ENVIRONMENTAL REGULATIONS AND PROCEEDINGS

The Company is subject to environmental laws and regulations in all
jurisdictions in which it has operating facilities. The Company periodically
makes capital expenditures for pollution abatement and control to meet
environmental requirements. At present, the Company has no plans for any
material capital expenditures for environmental control facilities. However, the
Company has experienced and continues to experience


                                       6
<PAGE>   8


operating costs relating to environmental matters, although certain costs have
been offset by the Company's successful waste minimization programs.

The Company believes that future environmental compliance expenditures will not
have a material adverse effect on its financial position and has established
allowances which it believes to be adequate to cover potential environmental
liabilities.

EXPORTS

Licenses are required from U.S. government agencies to export certain of the
Company's products from the United States. In particular, products with nuclear
applications are restricted, although limitations are placed on the export of
certain other pump, valve and mechanical seal products.

The Company's export sales from the United States to foreign unaffiliated
customers were $130,766 in 1998, $146,704 in 1997 and $140,842 in 1996.

             FORWARD-LOOKING INFORMATION IS SUBJECT TO RISK AND UNCERTAINTY

        This 1998 Annual Report on Form 10-K, including Management's Discussion
        and Analysis, contains various forward-looking statements and includes
        assumptions about the Company's future market conditions, operations and
        results. These statements are based on current expectations and are
        subject to significant risks and uncertainties. They are made pursuant
        to safe harbor provisions of the Private Securities Litigation Reform
        Act of 1995. Among the many factors that could cause actual results to
        differ materially from the forward-looking statements are: further
        changes in the already competitive environment for the Company's
        products or competitors' responses to the Company's strategies;
        political risks or trade embargoes affecting important country markets;
        the health of the petroleum, chemical and power industries; economic
        turmoil in areas outside the United States; continued economic growth
        within the United States; unanticipated difficulties or costs or
        reduction in benefits associated with the implementation of the
        Company's "Flowserver" business process improvement initiative,
        including software; the impact of the "Year 2000" computer issue; and
        the recognition of significant expenses associated with adjustments to
        realign the combined Company's facilities and other capabilities with
        its strategic and business conditions. The Company undertakes no
        obligation to publicly update or revise any forward-looking statement as
        a result of new information, future events or otherwise.

To the Board of Directors and Stockholders of BW/IP, Inc.

In our opinion, the consolidated statements of income and retained earnings and
of cash flows of BW/IP, Inc. (not presented separately herein) present fairly,
in all material respects, the results of operations and cash flows of BW/IP,
Inc. and its subsidiaries for the year ended December 31, 1996, in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Company's management; our responsibility is to express
an opinion on these financial statements based on our audit. We conducted our
audit 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
audit provides a reasonable basis for the opinion expressed above.

                         REPORT OF INDEPENDENT AUDITORS
                        ON FINANCIAL STATEMENT SCHEDULES


To the Board of Directors and Shareholders
Flowserve Corporation


We have audited the consolidated financial statements of Flowserve Corporation
and subsidiaries as of December 31, 1998 and 1997, and for each of the three
years in the period ending December 31, 1998, and have issued our report thereon
dated February 9, 1999 appearing on page 13 of the 1998 Annual Report (which
report and consolidated financial statements are incorporated by reference in
this Form 10-K). Our audits also included the financial statement schedule
listed in Item 14(a) of this Form 10-K. This schedule is the responsibility of
the Company's management. Our responsibility is to express an opinion on the
schedule based on our audits. We did not audit the 1996 financial statements of
BW/IP, Inc., a wholly owned subsidiary, which statements reflect total assets
constituting 49% of the related consolidated total as of December 31, 1996, and
total revenues constituting 45% of the related totals for the year ended
December 31, 1996. We have been furnished with the report of other auditors with
respect to the financial statement schedule listed in item 14(a) of the Form
10-K of BW/IP, Inc.

In our opinion, based on our audits and the report of other auditors, the
financial statement schedule referred to above, when considered in relation to
the basic financial statements taken as a whole, presents fairly in all material
respects the information set forth therein.

REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Flowserve Corporation

We have audited the accompanying consolidated balance sheets of Flowserve
Corporation and subsidiaries as of December 31, 1998 and 1997, and the related
consolidated statements of income, comprehensive income, shareholders' equity
and cash flows for each of the three years in the period ended December 31,
1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. We did not audit the 1996 financial statements
of BW/IP, Inc., a wholly owned subsidiary, which statements reflect total
revenues constituting 45% of the related totals for the year ended December 31,
1996. Those statements were audited by other auditors whose report thereon dated
January 28, 1997, has been furnished to us, and our opinion, insofar as it
relates to data included for BW/IP, Inc., is based solely on the report of the
other auditors.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, based on our audits and the report of other auditors, the
financial statements referred to above present fairly, in all material respects,
the consolidated financial position of Flowserve Corporation and subsidiaries at
December 31, 1998 and 1997, and the consolidated results of their operations and
their cash flows for each of the three years in the period ended December 31,
1998, in conformity with generally accepted accounting principles.

     In 1998, as discussed in Note 5 to the consolidated financial statements,
the Company changed its method of accounting for costing its inventory, and as
discussed in Note 7, changed its method of accounting for certain defined
compensation arrangements.

REPORT OF MANAGEMENT

The Company's management is responsible for preparation of the accompanying
consolidated financial statements. These statements have been prepared in
conformity with generally accepted accounting principles and include amounts
that are based on management's best estimates and business judgment. Management
maintains a system of internal controls, which in management's opinion provides
reasonable assurance that assets are safeguarded and transactions properly
recorded and executed in accordance with management's authorization. The
internal control system is supported by internal audits and is tested and
evaluated by the independent accountants in connection with their annual audit.
The Board of Directors pursues its responsibility for financial information
through an Audit and Finance Committee consisting entirely of independent
directors. This committee regularly meets not only with management, but also
separately with representatives of the independent accountants.

MANAGEMENT'S DISCUSSION AND ANALYSIS

OVERVIEW

The following discussion and analysis are provided to increase understanding of,
and should be read in conjunction with, the consolidated financial statements
and accompanying notes.

     Flowserve Corporation was created on July 22, 1997, through a merger of
equals between BW/IP, Inc. and Durco International Inc., which was accounted for
under the "pooling of interests" method of accounting. Accordingly, all
historical information has been restated, giving effect to the transaction as if
the two companies had been combined at the beginning of all periods presented.

     Flowserve produces engineered pumps, precision mechanical seals, automated
and manual quarter-turn valves, control valves and valve actuators, and provides
a range of related flow management services worldwide, primarily for the process
industries. Equipment manufactured and serviced by the Company is used in
industries that deal with difficult-to-handle and often corrosive fluids in
environments with extreme temperature, pressure, horsepower and speed.
Flowserve's businesses are affected by economic conditions in the United States
and other countries where its products are sold and serviced, by the
relationship of the U.S. dollar to other currencies and by the demand and
pricing for customers' products. The impact of these conditions is somewhat
mitigated by the strength and diversity of Flowserve's product lines and
geographic coverage.

RESULTS OF OPERATIONS

In general, 1998 results were lower than those of the two previous years due to
the downturn of economic conditions in the global markets in which the Company
participates. The economic turmoil that started in Asia in the second half of
1997 spread to other parts of the world, including Latin America. The
profitability of our chemical and petroleum customers, which collectively
represent about two-thirds of our business, was negatively impacted by the
economic weakness. This economic weakness contributed to a supply/demand
imbalance of chemicals and an oil price that averaged $11.12 per barrel in 1998,
compared with $17.78 per barrel in 1997 and $18.46 per barrel in 1996. As a
result, our customers reduced expenditures by delaying or canceling new projects
and reducing maintenance spending.

1997                $1,172        $1,152 
1996                $1,142        $1,098
</TABLE>

Bookings (incoming orders for which there are purchase commitments) were lower
in 1998 at $1,082.5 million, compared with $1,172.4 million in 1997 and $1,141.6
million in 1996. Sales decreased to $1,083.1 million in 1998 from $1,152.2
million in 1997 and $1,097.6 million in 1996. Bookings and sales declines in
1998 were largely a result of the economic and market factors previously
discussed.

     There were several other factors that affected the comparisons. A stronger
U.S. dollar, in relation to other currencies in which the Company conducts its
business, had the effect of reducing both bookings and sales when compared with
the prior year. The negative translation effect reduced 1998 bookings and sales
by about 2% and 1997 bookings and sales by about 4%.

     Comparisons are also impacted by the divestitures of several businesses in
1997 that contributed approximately $18 million to both bookings and sales in
1997 and $24 million in 1996. Several acquisitions affected the comparability as
well. Acquisitions made in 1998 added approximately $14 million to 1998 bookings
and sales, compared with 1997 and 1996. Acquisitions made in late 1996 and early
1997 added about $45 million to 1997 bookings and sales compared with 1996.

     In total, sales outside the United States were 42% in 1998, compared with
48% in 1997 and 52% in 1996. These sales declined due to weaker economies in
Asia and Latin America and negative currency translation effect.

BUSINESS SEGMENTS

Flowserve manages its operations through three business segments: Rotating
Equipment Division (RED) for engineered pumps; Flow Control Division (FCD) for
automated quarter-turn valves, control valves and valve actuators; and Flow
Solutions Division (FSD) for precision mechanical seals and flow management
services.

</TABLE>

     Sales of pumps and pump parts for the Rotating Equipment Division (RED)
decreased to $375.5 million from $412.8 million in 1997 and $402.8 million in
1996. The sales decline was generally due to reduced demand for chemical process
pumps as our chemical industry customers lowered their capital and maintenance
spending in response to weaker demand and pricing for their products. The
Company believes that the chemical market will continue to be weak in 1999. RED
sales were also lower due to reduced demand for nuclear parts and replacements.
RED sales increased in 1997 from 1996 due to the acquisition of the engineered
pump business of Stork Pompen, B.V. in January 1997.

     Operating income before special items, as a percentage of RED sales,
declined to approximately 11% in 1998 from about 12% in the previous two years.
The decline was due to the lower volume of more profitable chemical process
pumps, nuclear products and other parts and replacement business that more than
offset the benefits of the merger integration program.

</TABLE>

     Sales of valves and valve automation products for the Flow Control Division
(FCD) declined to $303.0 million in 1998 from $317.2 million in 1997. The
decrease was due to the weaker chemical market that reduced demand and placed
downward pressure on selling prices. The sales decrease was partly offset by the
acquisition of Valtek Engineering (United Kingdom licensee) in July 1998. FCD
sales were higher in 1997 than the $286.4 million recorded in 1996 due to
internal growth from control valves and the acquisition of Anchor/Darling Valves
in December 1996.

     Operating income before special items, as a percentage of sales, was 13.8%
in 1998, compared with 14.8% in 1997 and 13.0% in 1996. The decline in 1998 was
generally due to the lower sales volume. Operating income in 1998 was also
affected by lower selling prices and a reduced volume of higher-profit spare
parts. The improvement in 1997 over 1996 was due to sales growth and higher
margins from control valves and the Anchor/Darling Valves business.

</TABLE>

     Sales of services and seal products for the Flow Solutions Division (FSD)
increased to $433.6 million in 1998, compared with $430.1 million in 1997 and
$421.9 million in 1996. Sales related to service activities increased about 11%
in 1998 and 9% in 1997, despite the challenging market environment, due to an
increased focus on this business. These increases were partly offset by reduced
demand for seals due to economic weakness in Asia and Latin America, softness in
the chemical and petroleum markets and technological improvements in the
Company's seals that have reduced their mean time between failure.

     Operating income before special items, as a percentage of sales, increased
to 15.2% from 14.6% in 1997 and 13.2% in 1996. The improved margins were
generally due to the leveraging of a higher volume of sales and the benefits of
the merger integration program, partly offset by a seal product mix change to
lower margin products.

million ($1.88 per share) in 1998, compared with $82.1 million ($2.01 per share)
in 1997 and $74.1 million ($1.79 per share) in 1996. The decline in earnings in
1998 was largely due to the decline in sales and a lower gross profit margin.
The Company's share repurchase program contributed about $0.03 per share to
earnings in 1998, compared with the two prior years.

     The restructuring charges of $32.6 million in 1997 were related to the
Company's merger integration program, and the restructuring charges of $5.8
million in 1996 were related to the consolidation of certain operations in
Europe and Asia. Merger integration expense was $38.3 million in 1998 and $7.0
million in 1997. Merger integration expense was principally related to the
consolidation of the business units and headquarters, plant closings and the
formation of the Services Group of the Flow Solutions Division. Merger
transaction expense of $11.9 million in 1997 was for severance and other
expenses triggered by the merger, and investment banking, legal and other costs
required to effect the merger. In 1998, the Company recognized an obligation
under an executive employment agreement of $3.8 million recorded in selling and
administrative expense. In 1997, the Company sold its Metal Fab subsidiary and
realized a pretax gain of $11.4 million. The change in accounting principle
resulted in a one-time cumulative net-of-tax benefit of $1.2 million in 1998.
The accounting change was due to the required adoption of EITF 97-14,
"Accounting for Deferred Compensation Arrangements Where Amounts Earned Are Held
in a Rabbi Trust and Invested."

     Gross profit margin, gross profit as a percentage of sales, declined to
38.3% in 1998 from 39.0% in 1997 and 39.1% in 1996. The lower margin in 1998 was
generally related to valve price discounting and a seal product mix change
toward lower margin products. These reductions were partly offset by savings
related to the Company's merger integration program that reduced cost of sales
by approximately $9 million. These factors and lower sales contributed to a
decline in gross profit dollars to $415.3 million in 1998 from $448.9 million in
1997 and $428.9 million in 1996.

     Selling and administrative expense declined to $265.6 million in 1998 from
$285.9 million in 1997 and $283.4 million in 1996. Selling and administrative
expense in 1998 included $3.8 million in one-time costs associated with an
obligation under an executive employment agreement. As a percentage of sales,
selling and administrative expense was 24.5% (24.2% when adjusted for the
executive employment agreement) in 1998, compared with 24.8% in 1997 and 25.8%
in 1996. Reductions in selling and administrative expense were generally due to
savings from merger integration activities of about $12 million and lower sales.

     Research, engineering and development expense was $26.4 million in 1998,
compared with $26.9 million in 1997 and $24.5 million in 1996. The slight
decline in this expense in 1998 was principally due to savings realized from
merger integration activities.

     Interest expense was $13.2 million in 1998, compared with $13.3 million in
1997 and $12.1 million in 1996. Interest expense in 1998 was essentially the
same as the 1997 amount as the additional expense due to increased borrowings
throughout the year was offset by lower interest rates on the Company's variable
rate debt. The increase in 1997 over 1996 was primarily related to a full year
of expense on borrowings entered into during 1996.

     The effective tax rate before special items was 34.9% in 1998, compared
with 36.9% in 1997 and 34.4% in 1996. The decrease in 1998 was due to the
geographic mix of earnings and post-merger restructuring of operations. The
effective tax rate after special items in 1998 was the same as the effective tax
rate excluding special items. In 1997, the effective tax rate after special
items was 42.6% due to the nondeductibility of certain merger transaction
expenses, partly offset by certain tax benefits realized from the sale of a
subsidiary. The rate in 1996, after special items, was 34.4% due to one-time
benefits associated with the restructuring of certain European operations and
utilization of tax loss carryforwards.

MERGER INTEGRATION PROGRAM

In 1997, the Company developed a program designed to achieve the synergies
planned for the merger of BW/IP and Durco. The program included facility
rationalizations in North America and Europe, organizational realignments at the
corporate and division levels, procurement initiatives, investments in training
and support for service operations. In the fourth quarter of 1997, the Company
recognized a one-time restructuring charge of $32.6 million in connection with
this program. Other nonrecurring expenses related to the merger were incurred in
1998 and 1997 in order to achieve the planned synergies. These expenses of $38.3
million in 1998 and $7.0 million in 1997 were principally costs for consultants,
relocations and training. In 1998, the Company also spent $11.0 million in
capital expenditures related to this program.

     In 1998, the Company realized approximately $21 million of operating income
benefit related to the merger. In the fourth quarter of 1998, the Company
realized operating income benefits at a $28 million annualized rate. By 2001,
the Company expects to achieve the $45 million to $55 million of annual
operating income benefit planned from this program. The benefits result from
eliminating cost redundancies, capturing procurement savings and realizing
earnings increases from sales synergies.

BUSINESS PROCESS IMPROVEMENT INITIATIVE (FLOWSERVER)

In July 1998, the Company's Board of Directors approved an $18 million
expenditure for the first phase of Flowserver, a business process improvement
initiative. This program has costs and benefits incremental to the initial
merger integration program. The Flowserver initiative includes the
standardization of the Company's processes and the implementation of a global
information system to facilitate common best practices. The investment in this
business process improvement initiative is expected to approximate $120 million
over a four-year period. Approximately half of the expenditures associated with
this initiative are expected to be capitalized, with the balance expensed.
Completion of Flowserver is expected to result in more than $40 million of
annual operating income benefit in the first full year following completion of
the program and about a $100 million reduction in working capital requirements.

     In 1998, the Company incurred costs associated with this project of $5.1
million recorded as merger integration expense and $1.5 million as capital
expenditures.

Cash flows from operations and financing available under existing credit
agreements are the Company's primary sources of short-term liquidity. Cash flows
from operating activities in 1998 decreased to $54.1 million, compared with
$90.0 million in 1997 and $88.4 million in 1996. The decrease in cash flows in
1998 was primarily due to cash expended for restructuring and lower operating
profits. The increase in 1997 cash flows over 1996 resulted primarily from
increased earnings (before the noncash portion of the restructuring reserve).

</TABLE>

Capital expenditures, net of disposals, were $38.2 million in 1998, compared
with $39.6 million in 1997 and $35.7 million in 1996. Capital expenditures were
funded by operating cash flows. For each of the three years, capital
expenditures were invested in machinery and equipment, replacements and
upgrades. Capital expenditures in 1998 included about $11.0 million related to
the merger integration projects and $1.5 million related to Flowserver. In 1997,
the amount increased over 1996 predominately due to investments in low-cost
manufacturing facilities in India.

     During the second quarter of 1998, the Company initiated a $100 million
share repurchase program. In 1998, the Company spent approximately $64.5 million
to repurchase approximately 2.8 million, or 7.1%, of its outstanding shares. The
Company generally used credit facilities to fund the purchases. The timing of
future repurchases depends on market conditions, the market price of Flowserve's
common stock and management's assessment of the Company's liquidity and cash
flow needs.

     The Company has a $150 million revolving credit agreement of which $124
million was utilized at December 31, 1998. The Company also had other short-term
credit facilities under which $55.0 million was available for borrowing. At
December 31, 1998, total debt was 37.2% of the Company's capital structure,
compared with 27.1% at December 31, 1997. The ratio increased as planned due to
the share repurchase program. The interest coverage ratio of the Company's
indebtedness was 6.6 times interest at December 31, 1998, compared with 7.8
times interest at December 31, 1997.

     The Company believes that internally generated funds, together with access
to external capital resources, will be sufficient to satisfy existing
commitments and plans, and to provide adequate financial flexibility to take
advantage of potential strategic business opportunities should they arise.

     The return on average net assets based on results for 1998, before special
items, was 12.6%, compared with 13.7% for 1997. The decline is due to the lower
earnings discussed previously. Including the impact of special items, the return
on average net assets was 8.6% for 1998, compared with 9.0% for 1997. The return
on average shareholders' equity, before special items, was 20.0% in 1998,
compared with 20.4% in 1997. Return on shareholders' equity, including special
items, was 13.1% for 1998 and 13.0% for 1997.

     Acquisitions are an important part of the Company's strategy to increase
its earnings and build shareholder value. Accordingly, in 1998 the Company
acquired 100% of its joint venture in Singapore (previously 51% owned by the
Company), acquired certain assets and liabilities related to the business of two
licensees located in the United Kingdom and Australia and acquired the
outstanding shares of a valve-repair organization with operations in Belgium and
the Netherlands. Payments for acquisitions, net of cash acquired, were $20.0
million in 1998.

     Inflation during the past three years had little impact on the Company's
consolidated financial performance. Foreign currency translation had the effect
of reducing the Company's sales and earnings by 2% in 1998 and 4% in 1997.

MARKET RISKS ASSOCIATED WITH FINANCIAL INSTRUMENTS

The Company has certain market-sensitive financial instruments, including
long-term debt and investments in foreign subsidiaries. To evaluate the risks
associated with these instruments, the Company considered the impact of
unfavorable changes in the rates or values of these instruments as of December
31, 1998. The market changes, assumed to occur as of December 31, 1998, to
measure potential risk, are a 100 basis-point increase in market interest rates,
a 10% adverse change in all foreign currency exchange rates and a 10% decline in
the value of the Company's net investment in foreign subsidiaries.

     The Company considered the impact of a 100 basis-point increase in interest
rates and determined such an increase would not materially affect the Company's
earnings.

     The Company employs a foreign currency hedging strategy to minimize
potential losses in earnings or cash flows from unfavorable foreign currency
exchange rate movements. Foreign currency exposures arise from transactions,
including firm commitments and anticipated transactions, denominated in a
currency other than an entity's functional currency and from foreign denominated
revenues and profits translated back into U.S. dollars. The primary currencies
to which the Company has exposures are the German mark, British pound, Dutch
guilder and other European currencies; the Canadian dollar; the Mexican peso;
the Japanese yen; the Singapore dollar; and, the Australian dollar.

     Exposures are hedged primarily with foreign currency forward contracts that
generally have maturity dates less than one year. Company policy allows foreign
currency coverage only for identifiable foreign currency exposures and,
therefore, the Company does not enter into foreign currency contracts for
trading purposes where the objective is to generate profits. The potential loss
in fair value at December 31, 1998, based on year-end positions of outstanding
foreign currency contracts resulting from a hypothetical 10% adverse change in
all foreign currency exchange rates would not be material. The potential loss
would exclude hedges of existing balance sheet exposures. The losses in these
contracts would be offset by exchange gains in the underlying net monetary
exposures for which the contracts are designated as hedges.

     The Company generally views its investments in foreign subsidiaries from a
long-term perspective and, therefore, does not generally hedge these
investments. The Company uses capital structuring techniques to manage its
investment in foreign subsidiaries as deemed necessary. The Company's net
investment in foreign subsidiaries and affiliates, translated into U.S. dollars
using year-end exchange rates, was $106.4 million at December 31,1998. A
potential loss in value of the Company's net investment in foreign subsidiaries
resulting from a hypothetical 10% adverse change in quoted foreign exchange
rates at the end of 1998 would approximate $10.6 million.

EURO CONVERSION

On January 1, 1999, 11 European Union member states (Germany, France, the
Netherlands, Austria, Italy, Spain, Finland, Ireland, Belgium, Portugal and
Luxembourg) adopted the Euro as their common national currency. Until January 1,
2002, either the Euro or a participating country's national currency will be
accepted as legal tender. Beginning on January 1, 2002, Euro-denominated bills
and coins will be issued, and by July 1, 2002, only the Euro will be accepted as
legal tender. The Company does not expect future balance sheets, statements of
earnings or statements of cash flows to be materially impacted by the Euro
conversion.

YEAR 2000 COSTS

The Year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any of the Company's
computer systems that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in normal business activities.

     The Company has assessed how it might be impacted by the Year 2000 issue
and has formulated and commenced implementation of a comprehensive plan to
address all known aspects of the issue.

     The Company's plan encompasses its information systems and production and
other equipment that utilize date or time-oriented software or computer chips,
products, vendors and customers. The plan is being carried out in four phases:
1) assessment and plan development; 2) remediation; 3) testing; and, 4)
implementation. The Company's plan includes the use of independent experts as
considered necessary. The Company has engaged independent experts to evaluate
its Year 2000 plan and to assist in related issue identification, assessment,
remediation and testing efforts.

     With regard to information systems, production, and other equipment and
products, the Company is 100 percent complete with the assessment and plan
development phase. Planned remediation efforts are approximately 80 percent
complete. Testing is about 65 percent complete and implementation is about 50
percent complete. The Company expects that efforts in these areas will be
substantially complete by July 1999.

     The Company also is working with its vendors and customers to ensure Year
2000 compliance throughout its supply chain. The Company developed a
questionnaire that is used to survey vendors regarding compliance. In addition,
the Company has prepared a standard letter outlining the importance of, and
commitment to, resolving the Year 2000 issue in a timely manner, and this letter
is used to respond to inquiries from customers. Although the review is
continuing, the Company is not currently aware of any vendor or customer
circumstances that may have a material adverse impact on the Company. The
Company will seek alternative suppliers where circumstances warrant. The Company
can provide no assurance that Year 2000 compliance plans will be successfully
completed by suppliers and customers in a timely manner.

     The Company's preliminary estimate of the total cost for Year 2000
compliance is approximately $7.0 million, of which approximately $5.6 million
had been incurred through December 31, 1998. Virtually all of the amounts spent
to date relate to the cost to repair or replace software and associated
hardware. The Company's cost estimates include the amount specifically related
to remedying Year 2000 issues, as well as costs for improved systems that are
Year 2000 compliant and would have been acquired in the ordinary course of
business, but whose acquisition has been accelerated to ensure compliance by the
Year 2000.

     Incremental spending in addition to the $7.0 million has not been, and is
not expected to be, material because most Year 2000 compliance costs include
items that are part of the standard procurement and maintenance of the Company's
information systems and production and facilities equipment. Other non-Year 2000
efforts have not been materially delayed or impacted by the Company's Year 2000
initiatives.

     The Company has begun, but has not yet completed, a comprehensive analysis
of the operational problems and costs (including loss of revenues) that would be
likely to result from the failure by the Company and certain third parties to
complete efforts necessary to achieve Year 2000 compliance on a timely basis. A
contingency plan has not been developed for dealing with the most likely
worst-case scenario, as such a scenario has not yet been clearly identified. The
Company plans to complete such analysis and contingency planning by April 1999.

     The Company believes that the Year 2000 issue will not pose significant
operational problems for the Company. However, if all Year 2000 issues are not
properly identified, or assessment, remediation and testing are not completed in
a timely manner with respect to problems that are identified, there can be no
assurance that the Year 2000 issue will not have a material adverse impact on
the Company's results of operations or relationships with customers, vendors or
others. Additionally, there can be no assurance that the Year 2000 issues of
other entities will not have a material adverse impact on the Company's systems
or results of operations.

ACCOUNTING DEVELOPMENTS

In 1998, the Company adopted Statement of Financial Accounting Standards, (SFAS)
No. 130, "Reporting Comprehensive Income"; SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information"; and SFAS No. 132,
"Employers' Disclosures about Pensions and Other Postretirement Benefits." SFAS
No. 130 established standards for the presentation and display of comprehensive
income. SFAS No. 131 required public enterprises to disclose information about
their reporting segments consistent with the way management operates the
business. SFAS No. 132 consolidated the disclosures about pensions, settlement
and curtailment of pension plans and retirement benefits other than pensions
into a single set of requirements. In addition, the Company adopted EITF 97-14,
"Accounting for Defined Compensation Arrangements Where Amounts Earned Are Held
in a Rabbi Trust and Invested."

     In 1998, the Financial Accounting Standards Board also issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This standard is
effective for fiscal periods beginning after June 15, 1999. It establishes
accounting and reporting standards for derivative instruments and hedging
activities and is not expected to materially impact Flowserve's reported
financial position, results of operations or cash flows.

FORWARD-LOOKING INFORMATION IS SUBJECT TO RISK AND UNCERTAINTY

This 1998 Annual Report, including Management's Discussion and Analysis and the
Letter to Shareholders, contains various forward-looking statements and includes
assumptions about Flowserve's future market conditions, operations and results.
These statements are based on current expectations and are subject to
significant risks and uncertainties. They are made pursuant to safe harbor
provisions of the Private Securities Litigation Reform Act of 1995. Among the
many factors that could cause actual results to differ materially from the
forward-looking statements are: further changes in the already competitive
environment for the Company's products or competitors' responses to Flowserve's
strategies; political risks or trade embargoes affecting important country
markets; the health of the petroleum, chemical and power industries; economic
turmoil in areas outside the United States; continued economic growth within the
United States; unanticipated difficulties or costs or reduction in benefits
associated with the implementation of the Company's "Flowserver" business
process improvement initiative, including software; the impact of the "Year
2000" computer issue; and the recognition of significant expenses associated
with adjustments to realign the combined Company's facilities and other
capabilities with its strategic and business conditions. The Company undertakes
no obligation to publicly update or revise any forward-looking statement as a
result of new information, future events or otherwise.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollar amounts in thousands, except per share data)

NOTE 1: SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its wholly and majority-owned subsidiaries. Intercompany profits, transactions
and balances have been eliminated. Investments in unconsolidated affiliated
companies, which represent all nonmajority ownership interests, are carried on
the equity basis, which approximates the Company's equity interest in their
underlying net book value.

USE OF ESTIMATES

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

BASIS OF COMPARISON

Certain amounts in 1997 and 1996 have been reclassified to conform with the 1998
presentation.

BUSINESS COMBINATIONS

Business combinations accounted for under the pooling of interests method of
accounting combine the assets, liabilities and shareholders' equity of the
acquired entity with the Company's respective accounts at recorded values.
Prior-period financial statements have been restated to give effect to the
transactions as if they had occurred at the beginning of all periods presented.

     Business combinations accounted for under the purchase method of accounting
include the results of operations of the acquired business from the date of
acquisition. Net assets of the companies acquired are recorded at their fair
value to the Company at the date of acquisition and any excess of purchase price
over fair value is recorded as goodwill.

REVENUE RECOGNITION

Revenues and costs are generally recognized as units are shipped. Revenue for
certain longer-term contracts is recognized based on the percentage of
completion. Progress billings are generally shown as a reduction of inventory
unless such billings are in excess of accumulated costs, in which case such
balances are included in accrued liabilities.

SHORT-TERM INVESTMENTS AND CREDIT RISK

The Company places its temporary cash investments with financial institutions
and, by policy, limits the amount of credit exposure to any one financial
institution. These investments, with an original maturity of three months or
less when purchased, are classified as cash equivalents. They are highly liquid
with principal values not subject to significant risk of change due to interest
rate fluctuations. Credit risk related to accounts receivable is also limited
due to the large number of customers in the Company's customer base, the
Company's diverse product line and the dispersion of the Company's customers
across many geographic regions. As of December 31, 1998, the Company does not
believe that it had significant concentrations of credit risk.

ACCOUNTS RECEIVABLE

Accounts receivable are stated net of the allowance for doubtful accounts of
$4,533 and $5,059 at December 31, 1998 and 1997, respectively.

INVENTORIES

Inventories are stated at lower of cost or market. Cost is determined for
certain inventories by the last-in, first-out (LIFO) method and for other
inventories by the first-in, first-out (FIFO) method.

PROPERTY, PLANT AND EQUIPMENT, AND DEPRECIATION

Property, plant and equipment are stated on the basis of cost. Depreciation is
computed by the straight-line method based on the estimated useful lives of the
depreciable assets for financial statement purposes and by accelerated methods
for income tax purposes. The estimated useful lives of the assets are:

<TABLE>
<S>                                                     <C>
Buildings, improvements, furniture and fixtures         5 to 35 years
Machinery and equipment                                 3 to 12 years
Capital leases                                          5 to 25 years
</TABLE>

INTANGIBLES

The excess cost over the fair value of net assets acquired (goodwill) is
amortized on a straight-line basis over 15 to 40 years. The carrying value of
goodwill is reviewed as the facts and circumstances suggest that it may be
impaired. If this review indicates that goodwill will not be recoverable, as
determined based on the undiscounted cash flows of the entity acquired over the
remaining amortization period, the Company's carrying value of the goodwill will
be adjusted accordingly. Intangibles are stated net of accumulated amortization
of $6,426 and $5,266 as of December 31, 1998 and 1997, respectively.

HEDGING/FORWARD CONTRACTS

The Company is party to forward contracts for purposes of hedging certain
transactions denominated in foreign currencies. The Company has a
risk-management and derivatives policy statement outlining the conditions in
which the Company can enter into hedging or forward transactions. Gains and
losses on forward contracts qualifying as hedges are deferred and included in
the measurement of the related foreign currency transaction. Gains and losses on
hedges of existing assets or liabilities are included in the carrying amounts of
those assets or liabilities and are ultimately recognized in income as part of
those carrying amounts. Gains and losses related to hedges of anticipated
transactions are recognized in income as the transactions occur. The Company is
exposed to credit-related losses in the event of nonperformance by
counterparties to financial instruments, but it expects all counterparties to
meet their obligations given their high credit ratings. As of December 31, 1998,
the Company had no significant outstanding hedges or forward contracts with
third parties. The carrying amounts of the financial instruments (primarily
accounts receivable and long-term debt), approximate fair value as defined under
Statement of Financial Accounting Standards (SFAS) No. 107, "Disclosures about
Fair Value of Financial Instruments." Fair value is estimated by reference to
quoted prices by financial institutions.

FOREIGN CURRENCY TRANSLATION

Assets and liabilities of the Company's foreign affiliates, other than those
located in highly inflationary countries, are translated at current exchange
rates, while income and expenses are translated at average rates for the period.
For entities in highly inflationary countries, a combination of current and
historical rates is used to determine currency gains and losses resulting from
financial-statement translation and those resulting from transactions.
Translation gains and losses are reported as a component of shareholders'
equity, except for those associated with highly inflationary countries, which
are reported directly in the consolidated statements of income.

ACCOUNTING DEVELOPMENTS

In 1998, the Company adopted Statement of Financial Accounting Standards, (SFAS)
No. 130, "Reporting Comprehensive Income"; SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information"; and SFAS No. 132,
"Employers' Disclosures about Pensions and Other Postretirement Benefits." SFAS
No. 130 established standards for the presentation and display of comprehensive
income. SFAS No. 131 required public enterprises to disclose information about
their reporting segments consistent with the way management operates the
business. SFAS No. 132 consolidated the disclosures about pensions, settlement
and curtailment of pension plans and retirement benefits other than pensions
into a single set of requirements. In addition, the Company adopted EITF 97-14,
"Accounting for Defined Compensation Arrangements Where Amounts Earned Are Held
in a Rabbi Trust and Invested."

     In 1998, the Financial Accounting Standards Board also issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This standard is
effective for fiscal periods beginning after June 15, 1999. It establishes
accounting and reporting standards for derivative instruments and hedging
activities and is not expected to materially impact Flowserve's reported
financial position, results of operations or cash flows.

EARNINGS PER SHARE

In 1997, the Company adopted SFAS No. 128, "Earnings Per Share," that
established standards for computing and presenting earnings per share. SFAS 128
requires dual presentation of basic and diluted earnings per share on the face
of the income statement and requires a reconciliation of the numerator and
denominator of the basic earnings per share computation to the numerator and
denominator of the diluted earnings per share computation. The Company's
potentially dilutive common stock equivalents have been immaterial for all
periods presented. Accordingly, basic earnings per share is equal to diluted
earnings per share and is presented on the same line for income statement
presentation.

INCOME TAXES

The Company accounts for income taxes under the asset and liability method in
accordance with SFAS No. 109, "Accounting for Income Taxes." This approach
requires the recognition of deferred tax assets and liabilities for the expected
future tax consequences of temporary differences between the carrying amounts
and the tax basis of assets and liabilities.

STOCK-BASED COMPENSATION

The Company follows Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" (APB No. 25), and related interpretations in
accounting for its employee stock options. Under APB No. 25, no compensation
expense is recorded if the exercise price of the Company's stock options equals
the market price of the underlying stock on the date of grant. Accordingly, the
Company has no compensation expense recorded.

NOTE 2: MERGER

On July 22, 1997, shareholders of Durco International Inc. (Durco) and BW/IP,
Inc. (BW/IP) voted to approve a merger of the companies in a stock-for-stock
merger of equals that was accounted for as a pooling of interests transaction
(the merger). As part of the merger agreement, the Company changed its name from
Durco to Flowserve Corporation. The Company issued approximately 16,914,000
shares of common stock in connection with the merger. BW/IP shareholders
received 0.6968 shares of the Company's common stock for each previously owned
share of BW/IP stock.

     The consolidated financial statements, including the accompanying notes
thereto, have been restated for all periods prior to the merger to include the
financial position, results of operations, and cash flows of BW/IP and Durco as
if the merger had occurred at the beginning of all periods presented.

     In connection with the merger, the Company recorded a one-time charge of
$11,900 for merger-related expenses in 1997. These expenses included severance
and other expenses triggered by the merger and investment banking fees, legal
fees and other costs related to the merger, which were primarily nondeductible
for tax purposes.

     In 1997, the Company developed a merger integration program that includes
facility rationalizations in North America and Europe, organizational
realignments at the corporate and division levels, procurement initiatives,
investments in training and support for the service operations. In the fourth
quarter of 1997, the Company recognized a one-time restructuring charge of
$32,600 related to this program. Other nonrecurring expenses related to the
merger (merger integration expense) were incurred in 1998 and 1997 in order to
achieve the planned synergies. These expenses of $38,300 in 1998 and $7,000 in
1997 were principally for costs for consultants, relocation and training. In
1998, the Company also spent $11,000 in capital expenditures related to this
program.

     Merger-related transactions were:

     In July 1998, the Company's Board of Directors approved an $18 million
expenditure for the first phase of "Flowserver." This business process
improvement program has costs and benefits incremental to the initial merger
integration program. Flowserver includes the standardization of the Company's
processes and the implementation of a global information system to facilitate
common best practices. The investment in this business process improvement
initiative is expected to approximate $120 million over a four-year period.
Approximately half of the costs associated with this program are expected to be
capitalized, with the balance expensed.

     In 1998, the Company incurred costs associated with this project of $5.1
million recorded as merger integration expense and $1.5 million as capital
expenditures.

NOTE 3: ACQUISITIONS AND DISPOSITIONS

In July 1998, the Company purchased certain assets and liabilities of the Valtek
Engineering Division of Allen Power Engineering, Limited, from Rolls-Royce plc.
The Valtek Engineering Division was the British licensee for many of Flowserve's
control valve products, with exclusive territorial rights for portions of
Europe, the Middle East and Africa since 1971.

     In September 1998, the Company acquired the remaining 49% ownership
interest in Durametallic Asia Pte. Ltd., a fluid sealing manufacturer in
Singapore, from its joint-venture partner. Also in 1998, the Company acquired
the outstanding shares of ARS Lokeren NV, a Belgian company, and ZAR Beheer BV,
a Dutch company, which specialize in the service and repair of industrial
valves, with service and repair facilities near Rotterdam, the Netherlands, and
Ghent and Antwerp, Belgium.

     In 1997, the Company purchased the 49% remaining shares of its joint
venture in Argentina, Byron Jackson Argentina I.C.S.A., and purchased the
engineered pump business of Stork Pompen, B.V. In 1996, the Company acquired
certain assets and liabilities of Anchor/Darling Valves.

     The Company sold its wholly owned subsidiary, Metal Fab Machine
Corporation, for $18,793 in December 1997, and realized a pretax gain of
$11,376. In addition, in 1997, the Company sold its Filtration Systems Division.

NOTE 4: STOCK PLANS

The Company maintains a shareholder-approved stock option plan, which provides
for the grant of 1,500,000 options to purchase shares of the Company's common
stock. At December 31, 1998, approximately 439,000 options were available for
grant. Options have been granted to officers and employees to purchase shares of
common stock at a price equal to fair market value at the date of grant.
Generally, these options, whether granted from the current or prior plans,
become exercisable over staggered periods, but may not be exercised after 10
years from the date of the grant. The aggregate number of shares exercisable was
1,703,171 at December 31, 1998; 1,707,677 at December 31, 1997; and 915,509 at
December 31, 1996.

     Pro forma information regarding net earnings and earnings per share is
required by SFAS No. 123, which also requires that the information be determined
as if the Company had accounted for its stock options granted subsequent to
December 31, 1994, under the fair value method of that Statement. The "fair
value" for these options at the date of grant was estimated using a binomial
option pricing model (a modified Black-Scholes model). The assumptions used in
this valuation are as follows:

     The options granted had a weighted average "fair value" per share on date
of grant of $6.14 in 1998, $10.69 in 1997 and $10.42 in 1996. For purposes of
pro forma disclosure, the estimated fair value of the options is amortized to
expense over the options vesting periods. The Company's pro forma information is
as follows:

</TABLE>

     Because the determination of the fair value of all options granted includes
an expected volatility factor and because additional option grants are expected
to be made each year, the above pro forma disclosures are not representative of
pro forma effects for future years.

     The restricted stock plan approved by shareholders in 1998 authorized the
grant of up to 800,000 shares of the Company's common stock. The 1989 restricted
stock plan, which expired following the 1998 annual meeting of shareholders,
authorized the grant of up to 337,500 shares of the Company's common stock. In
general, the shares cannot be transferred for a period of at least one but not
more than 10 years and are subject to forfeiture during the restriction period.
The fair value of the shares is amortized to compensation expense over the
periods in which the restrictions lapse. Restricted stock grants were 10,165
shares in 1998, 21,700 shares in 1997 and 29,900 shares in 1996. The weighted
average fair value of the restricted stock grants at date of grant was $24.07 in
1998, $27.73 in 1997 and $25.84 in 1996. Total compensation expense recognized
in the income statement for all stock-based awards was $485 in 1998, $510 in
1997 and $584 in 1996.

     The percentage of inventory accounted for by the last-in first-out (LIFO)
method increased in 1998 as the U.S. operations of the former BW/IP changed its
method of accounting for inventories to LIFO during the year. Because the
December 31, 1997, BW/IP inventory valued at FIFO is the opening LIFO inventory,
there is neither a cumulative effect to January 1, 1998, nor pro forma amounts
of retroactively applying the change to LIFO. The effect of the change in 1998
was not significant.

     In 1997, the Company entered into a $150,000 revolving credit agreement
with the option to increase borrowings up to $200,000. As of December 31, 1998,
$124,000 was outstanding. The Company has an interest-rate swap that fixes
$50,000 usage of the revolving credit facility at 6.74%.

     In connection with a German acquisition, the Company converted a
deutsche-mark obligation through a currency swap agreement against its U.S.
dollar private placement to fund the acquisition. The effective rate on the loan
swap was 8.94%. The maturity and repayment terms of the swap match precisely the
maturity and repayment term of the underlying debt.

     In 1992, the Company issued $50,000 Senior Notes requiring annual payments
of $8,333 through 1999, bearing interest at 7.92%, of which $8,333 was
outstanding at December 31, 1998. In 1996, the Company issued $30,000 Senior
Notes requiring annual principal payments of $6,000 commencing in 2002, bearing
interest of 7.14%. In 1997, the Company issued $20,000 in Senior Notes, bearing
interest of 7.17% with principal payments of $4,000 due annually, commencing in
2003.

     The provisions of the credit agreements require the Company to meet or
exceed specified financial covenants that are defined in the agreements. The
agreements also contain limitations or restrictions relating to new indebtedness
and liens, disposition of assets and payment of dividends or other
distributions. All such covenants were met in each of the years presented. The
most restrictive of these include a debt-to-capital ratio and a minimum tangible
net worth requirement.

     As of December 31, 1998, the Company had $9,897 of contingent obligations
relating to bank guarantees and performance bonds outstanding.

     At December 31, 1998 and 1997, the Company had short-term credit facilities
available from banks under which it could borrow at local market rates up to
$58,500 and $61,521, respectively. These facilities are presented as notes
payable on the Company's consolidated balance sheets. Under these facilities,
the Company had borrowings outstanding of $3,488 at December 31, 1998, and
$5,644 at December 31, 1997. The weighted average interest rate on these
borrowings was 6.0% at December 31, 1998, and was 4.8% at December 31, 1997.
Borrowings against these facilities were primarily to support the operations of
foreign subsidiaries.

     The Company has noncancelable operating leases for certain offices, service
and quick response centers, certain manufacturing and operations facilities, and
machinery, equipment and automobiles. Rental expense relating to operating
leases was $11,798 in 1998, $15,000 in 1997 and $15,100 in 1996.

NOTE 7: DEFERRED COMPENSATION - RABBI TRUST

In September 1998, the Company adopted the provisions of EITF No. 97-14
"Accounting for Deferred Compensation Arrangements Where Amounts Earned Are Held
in a Rabbi Trust and Invested." This standard established new guidelines for
deferred compensation arrangements where amounts earned by an employee are
invested in the employer's stock that is placed in a Rabbi Trust. The EITF
requires that the Company's stock held in the trust be recorded at historical
cost, the corresponding deferred compensation liability recorded at the current
fair value of the Company's stock and the stock held in the Rabbi Trust
classified as treasury stock. The difference between the historical cost of the
stock and the fair value of the liability at September 30, 1998, has been
recorded as a cumulative effect of a change in accounting principle of $1,220,
net of tax. Prior-year financial statements have not been restated to reflect
the change in accounting principle. The effect of the change on 1997 income
before the cumulative effect would have been a reduction of $490. The effect of
the change on 1996 income would not have been material.

NOTE 8: RETIREMENT BENEFITS

The Company sponsors several noncontributory defined benefit pension plans,
covering approximately 60% of U.S. employees, which provide benefits based on
years of service and compensation. Retirement benefits for all other employees
are provided through defined contribution pension plans and government-sponsored
retirement programs. All defined benefit pension plans are funded based on
independent actuarial valuations to provide for current service and an amount
sufficient to amortize unfunded prior service over periods not to exceed 30
years.

     The Company sponsors several defined contribution pension plans covering
substantially all U.S. and Canadian employees and certain other foreign
employees. Employees may contribute to these plans, and these contributions are
matched in varying amounts by the Company. The Company may also make additional
contributions for eligible employees. Defined contribution pension expense for
the Company was $7,309 in 1998, $7,733 in 1997 and $6,903 in 1996.

     The Company also sponsors several defined benefit post-retirement health
care plans covering approximately 77% of future retirees and most current
retirees in the United States. These plans are for medical and dental benefits
and are provided through insurance companies and health maintenance
organizations. The plans include participant contributions, deductibles,
co-insurance provisions and other limitations, and are integrated with Medicare
and other group plans. The plans are funded as insured benefits and health
maintenance organization premiums are incurred.

</TABLE>

     The assumed annual rates of increase in per capita costs for periods prior
to Medicare were 8.0% for 1998 with a gradual decrease to 6.0% for 2002 and
future years, and for periods after Medicare, 6.0% for 1998 with a gradual
decrease to 5.0% for 2000 and future years.

     Increasing the assumed rate of increase in post-retirement benefit costs by
1.0% in each year would increase net post-retirement benefit expense by
approximately $297 and accumulated post-retirement benefit obligations by
$3,689. Reducing the assumed rate of decrease in post-retirement benefit costs
by 1.0% in each year would reduce net post-retirement benefit expense by
approximately $273 and accumulated benefit obligations by $3,553. The Company
made contributions to the defined benefit post-retirement plan of $3,849 in 1998
and $3,176 in 1997.

NOTE 9: CONTINGENCIES

As of December 31, 1998, the Company was involved as a "potentially responsible
party" (PRP) at six former public waste disposal sites that may be subject to
remediation under pending government procedures. The sites are in various stages
of evaluation by federal and state environmental authorities. The projected cost
of remediating these sites, as well as the Company's alleged "fair share"
allocation, is uncertain and speculative until all studies have been completed
and the parties have either negotiated an amicable resolution or the matter has
been judicially resolved. At each site, there are many other parties who have
been similarly identified, and the identification and location of additional
parties is continuing under applicable federal or state law. Many of the other
parties identified are financially strong and solvent companies that appear able
to pay their share of the remediation costs. Based on the Company's preliminary
information about the waste disposal practices at these sites and the
environmental regulatory process in general, the Company believes that it is
likely that ultimate remediation liability costs for each site will be
apportioned among all liable parties, including site owners and waste
transporters, according to the volumes and/or toxicity of the wastes shown to
have been disposed of at the sites.

     The Company is a defendant in numerous pending lawsuits (which include, in
many cases, multiple claimants) that seek to recover damages for personal injury
allegedly resulting from exposure to asbestos-containing products formerly
manufactured and distributed by the Company. All such products were used within
self-contained process equipment, and management does not believe that there was
any emission of ambient asbestos fiber during the use of this equipment.



FLOWSERVE 1998 ANNUAL REPORT
                                                                              33
<PAGE>   22

     The Company is also a defendant in several other products liability
lawsuits that are insured, subject to the applicable deductibles, and certain
other noninsured lawsuits received in the ordinary course of business.
Management believes that the Company has adequately accrued estimated losses for
such lawsuits. No insurance recovery has been projected for any of the insured
claims, because management currently believes that all will be resolved within
applicable deductibles. The Company is also a party to other noninsured
litigation that is incidental to its business, and, in management's opinion,
will be resolved without a material impact on the Company's financial
statements.

     Although none of the aforementioned gives rise to any additional liability
that can now be reasonably estimated, the Company believes such costs will be
immaterial. The Company will continue to evaluate these contingent loss
exposures and, if they develop, recognize expense as soon as such losses can be
reasonably estimated.

NOTE 10: SHAREHOLDERS' EQUITY

In 1997, the Company increased its authorized $1.25 par value common stock from
60,000,000 to 120,000,000 shares. The authorized shares were increased in
connection with the merger of Durco and BW/IP resulting in the formation of
Flowserve Corporation. At both December 31, 1998 and 1997, the Company had
authorized 1,000,000 shares of $1.00 par value preferred stock.

     Each share of the Company's common stock contains a preferred stock
purchase right. These rights are not currently exercisable and trade in tandem
with the common stock. The rights become exercisable and trade separately in the
event of certain significant changes in common stock ownership or on the
commencement of certain tender offers that, in either case, may lead to a change
of control of the Company. Upon becoming exercisable, the rights provide
shareholders the opportunity to acquire a new series of Company preferred stock
to be then automatically issued at a pre-established price. In the event of
certain forms of acquisition of the Company, the rights also provide Company
shareholders the opportunity to purchase shares of the acquiring company's
common stock from the acquirer at a 50% discount from the current market value.
The rights are redeemable for $0.022 per right by the Company at any time prior
to becoming exercisable and will expire in August 2006.

     At December 31, 1998, approximately 3,511,000 shares of common stock were
reserved for exercise of stock options and for grants of restricted stock.

The provision for taxes on income consisted of the following:

     The Company has recorded valuation allowances to reflect the estimated
amount of deferred tax assets that may not be realized due to the expiration of
net operating loss and foreign tax credit carryforwards. The net changes in the
valuation allowances were attributable to utilization and expiration of net
operating loss carryforwards partially offset by an increase in expected
nonutilization of net operating loss and credit carryforwards. The Company had
approximately $26,400 of net operating loss carryforwards at December 31, 1998,
the majority of which were generated in non-U.S. jurisdictions in which net
operating losses do not expire.

     Earnings before income taxes comprised:

     Undistributed earnings of the Company's non-U.S. subsidiaries amounted to
approximately $187,000 at December 31, 1998. These earnings are considered to be
indefinitely reinvested and, accordingly, no additional U.S. income taxes or
non-U.S. withholding taxes have been provided. Determination of the amount of
additional taxes that would be payable if such earnings were not considered
indefinitely reinvested is not practical.

     The Company evaluates segment performance and allocates resources based on
operating income or loss before special items and taxes. The accounting policies
of the reportable segments are the same as described in Note 1: Significant
Accounting Policies. Intersegment sales and transfers are recorded at cost plus
a profit margin. This intersegment profit is eliminated in consolidation.

February 9, 1999



Board of Directors and Shareholders
The Flowserve Corporation
222 West Las Colinas Blvd.
Irving, Texas 75039

Dear Sirs:

Note 5 of Notes to the Consolidated Financial Statements of the Flowserve
Corporation and Subsidiaries (the "Company" or "Flowserve") incorporated by
reference in its Annual Report on Form 10-K for the year ended December 31, 1998
describes a change in the method of accounting for inventories at certain of the
Company's domestic locations. The Company has changed from the first-in,
first-out to the last-in first-out ("LIFO") method of accounting for these
inventories representing twenty-three percent of the Company's inventories on a
FIFO basis at December 31, 1998. You have advised us that you believe that the
change is to a preferable method in your circumstances because:

         1)   The LIFO method will provide for a better matching of current
              production costs with current revenues as the most recently
              incurred costs will be expensed as inventory is sold.

         2)   Adoption of LIFO at the former BW/IP, Inc. locations will improve
              consistency among the domestic operations of Flowserve, as all
              U.S. operations will then be using the LIFO method.

There are no authoritative criteria for determining a preferable inventory
cost-flow method based on the particular circumstances; however, we conclude
that the change in the method of accounting for inventories at the former BW/IP,
Inc. locations is an acceptable alternative method which, based on your business
judgment to make this change for the reasons cited above, is preferable in your
circumstances.

                                                     Very truly yours,


                                                     /s/ Ernst & Young LLP
