ITEM 1. BUSINESS.

   Ryerson Tull, Inc. ("Ryerson Tull"), a Delaware corporation, is the sole
stockholder of Joseph T. Ryerson & Son, Inc. ("Ryerson") and J.M. Tull Metals
Company, Inc. ("Tull") (unless the context indicates otherwise, Ryerson Tull,
Ryerson and Tull, together with their subsidiaries, are collectively referred
to herein as the "Company"). The Company has a single business segment, which
is comprised primarily of Ryerson and Tull, leading steel service,
distribution and materials processing organizations. The Company also owns
certain joint venture interests, which are not material, in certain foreign
operations discussed below.

Operations

   The Company conducts its materials distribution operations in the United
States through its operating subsidiaries, Ryerson and Tull; in Canada through
Washington Specialty Metals, Inc.; in Mexico through Ryerson de Mexico, S.A.
de C.V.; in China through Shanghai Ryerson Limited; and in India through Tata
Ryerson Limited; and is organized into five business units along regional and
product lines. The Company is a leading metals service center in the United
States based on sales revenue, with 1999 sales of $2.76 billion. It has a
current U.S. market share of approximately 11%, based on its analysis of data
prepared by the Steel Service Center Institute ("SSCI"). The Company
distributes and processes metals and other materials throughout the
continental United States, and is among the largest purchasers of steel in the
United States.

Industry Overview

   Primary steel producers typically sell steel in the form of standard-sized
coils, sheets, plates, structurals, bars and tubes, and generally sell in
large volumes with long lead times for production and delivery. Other primary
metals producers, such as producers of stainless steel and aluminum, also
typically sell their products in large volumes with long lead times for
production and delivery. However, many customers seek to purchase metals with
customized specifications, including value-added processing, in smaller
volumes, on shorter lead times and with more reliable delivery than primary
metals producers are able to provide. Metals service centers act as
intermediaries between primary metals producers and customers by purchasing
metals in a variety of shapes and sizes from primary metals producers in large
volumes, allowing metals service centers to take advantage of producer
economies of scale resulting in lower costs of materials purchased, and
engaging in a variety of distribution and value-added processing operations to
meet the demands of specific customers. Because metals service centers
purchase metals from a number of primary producers, they can maintain a
consistent supply of various types of metal used by their customers. By
purchasing products from metals service centers, customers may be able to
lower their inventory levels, decrease the time between the placement of an
order and receipt of materials and reduce internal expenses, thereby lowering
their total cost of raw materials. The Company believes that the increased
prevalence of just-in-time inventory needs of manufacturers and intermediate
processors has made and will continue to make the value-added inventory,
processing and delivery functions performed by metals service centers more
important in the metals market.

   The industry is cyclical, impacted both by market demand and metals supply.
Periods of strong and weak market demand principally are due to the cyclical
nature of the industries in which the largest consumers of metals operate. Any
significant slowdown in one or more of those industries could have a material
adverse effect on the demand for metals, resulting in lower prices for metals
and reduced profitability for metals service centers, including the Company.
Metals prices and metals service center profitability generally improve as
metal-consuming industries recover from economic downturns. However, excess
supply of metals can, even in periods of strong demand, result in lower prices
for metals and adversely impact profitability.

   The industry is comprised of many companies, the majority of which have
operations limited as to product line and size of inventory, with customers
located in a specific geographic area. Based on SSCI data, the

                                       2
<PAGE>

Company believes that the industry is comprised of between 750 and 1,000
service centers, operating out of approximately 2,000 locations and servicing
approximately 300,000 customers. The industry is highly fragmented, consisting
of a large number of small companies and a few relatively large companies. In
general, competition is based on quality, service, price and geographic
proximity. Based on the Company's analysis of SSCI data, the industry handled
approximately 29.4 million tons or approximately 28.6% of the metals
distributed in the United States in 1999.

   The industry is divided into three major groups: general line service
centers, specialized service centers and processing centers, each of which
targets different market segments. General line service centers handle a broad
line of metals products and tend to concentrate on distribution rather than
processing. General line service centers range in size from one location to a
nationwide network of locations. For general line service centers, individual
order size in terms of dollars and tons tends to be small relative to
processing centers, while the total number of orders is typically very high.
Specialized service centers focus their activities on a narrower range of
product and service offerings than general line companies. Such service
centers provide a narrower range of services to their customers and emphasize
product expertise and lower operating costs, while maintaining a moderate
level of investment in processing equipment. Processing centers typically
process large quantities of steel purchased from primary producers for resale
to large industrial customers, such as the automotive industry. Because orders
are typically large, operation of a processing center requires a significant
investment in processing equipment.

   The Company competes with many other general line service centers,
specialized service centers and processing centers on a regional and local
basis, some of which may have greater financial resources and flexibility than
the Company. The Company also competes to a lesser extent with primary steel
producers. Primary steel producers typically sell to very large customers that
require regular shipments of large volumes of steel. Although these large
customers sometimes use metals service centers to supply a portion of their
metals needs, metals service center customers typically are consumers of
smaller volumes of metals than customers of primary steel producers. Although
the Company purchases metals from steelmakers, some of the Company's
competitors purchase a higher percentage of metals than the Company from
foreign steelmakers. Such competitors may benefit from favorable exchange
rates or other economic or regulatory factors that may result in a competitive
advantage. This competitive advantage may be offset somewhat by higher
transportation costs and less dependable delivery times associated with
importing metals into the United States. Excess capacity of metals relative to
demand in the industry since mid-1995 led to a weakening in prices. As a
result, the Company was reducing its prices from mid-1995 through mid-1999 to
remain competitive. Pricing stabilized in the second half of 1999.

Products and Services

   The Company carries a full line of carbon steel, stainless steel and
aluminum, and a limited line of alloy steel, nickel, red metals and plastics.
These materials are inventoried in a number of shapes, including coils,
sheets, rounds, hexagons, square and flat bars, plates, structurals and
tubing.

   The following table shows the Company's percentage of sales revenue by
major product lines for 1997, 1998 and 1999:

   More than one-half of the materials sold by the Company is processed. The
Company uses techniques such as sawing, slitting, blanking, pickling, cutting
to length, leveling, flame cutting, laser cutting, edge trimming, edge
rolling, fabricating and grinding to process materials to specified thickness,
length, width, shape and surface quality pursuant to specific customer orders.
Among the most common processing techniques used by the Company are pickling,
a chemical process using an acidic solution to remove surface oxide, commonly
called "scale," from steel which develops after the steel is hot rolled;
slitting, which is cutting coiled metals to specified widths along the length
of the coil; leveling, which is flattening metals and cutting them to exact
lengths; and edge rolling, a process which imparts round or smooth edges.
Although the Company often uses third-party fabricators to outsource certain
limited processes that the Company is not able to perform internally,
outsourcing these processes does not affect a significant part of the
Company's operations or constitute a significant part of the its operating
costs and expenses.

   The plate burning and fabrication processes are particularly important to
the Company. These processes require sophisticated and expensive processing
equipment. As a result, rather than making investments in such equipment,
manufacturers have increasingly outsourced these processes to metals service
centers. The Company has flame or laser cutting capacity in 43 of its 67
facilities.

   The Company also provides services and technical advice to its customers as
an integral part of providing products to its customers. It does not charge
customers separately for such services or advice, but rather includes the
costs of such services and advice in the price of products sold to such
customers.

   The Company's services include: just-in-time delivery, production of kits
containing multiple products for ease of assembly by the customer, the
provision of the Company-owned materials to the customer and the placement of
the Company employees at a customer's site for inventory management,
production and technical assistance. The Company also provides special
stocking programs in which products that would not otherwise be stocked by the
Company are held in inventory to meet certain customers' needs. The foregoing
services are designed to reduce customers' costs by minimizing their
investment in inventory and improving their production efficiency.

Customer Base

   The Company's customer base is diverse, numbering over 50,000. No customer
accounted for more than 5% of Company sales in 1999, and the top ten customers
accounted for approximately 13% of its sales in 1999. The Company's customer
base includes most metal-consuming industries, most of which are cyclical. The
following table shows the Company's percentage of sales revenue by class of
customers for 1997, 1998 and 1999:

</TABLE>

   The Company's flat-rolled processing business unit, Ryerson Tull Coil
Processing, generally serves a customer base that differs from the Company's
general line service center business. A large portion of Ryerson Tull Coil
Processing's customers has supply contracts typically at fixed prices and from
three months to one

                                       4
<PAGE>

year in duration. Ryerson Tull Coil Processing has a small number of
arrangements with large customers that extend beyond one year. Ryerson Tull
Coil Processing attempts to limit its financial exposure on these fixed-price
sales arrangements by entering into fixed-price supply arrangements with one
or more suppliers for comparable periods of time. Ryerson Tull Coil
Processing's customers often seek large quantities of carbon sheet product
that have undergone one or more of the following processes: pickling, cutting
to length, slitting, tension leveling, texturing or blanking. Many of Ryerson
Tull Coil Processing's approximately 650 customers are in the transportation
equipment, appliance, office furniture or cabinetry businesses.

Suppliers

   In 1999, the Company purchased approximately 3.4 million tons of materials
from many suppliers throughout the world. The Company's top 25 suppliers
accounted for approximately 60% of 1999 purchase dollars. The only supplier
that accounted for 10% or more of the 1999 purchase dollars was Ispat Inland
Inc. ("Ispat") which accounted for approximately 13.5% of purchase dollars.
The terms of these arrangements were negotiated between the Company and Ispat
and are similar to other large supply arrangements the Company has with other
suppliers for similar products.

   The Company purchases the majority of its inventories in the open market at
prevailing market prices. However, occasionally the Company enters into long-
term, fixed-price supply contracts to offset its long-term, fixed-price sales
contracts in order to minimize its financial exposure.

   Because the Company uses many suppliers and because there is a substantial
overlap of product offerings from these suppliers, the Company believes it
will be able to meet its materials requirements for the foreseeable future.
The Company works with and monitors its suppliers in order to obtain
improvements in price, quality, service, delivery and performance. The Company
believes it has good relationships with most of its suppliers.

Sales and Marketing

   Each of the Company's business units maintains its own sales and marketing
force. In addition to its office sales staff, the Company markets and sells
its products through the use of its field sales force that has extensive
product and customer knowledge and through a comprehensive catalog of the
Company's products. The Company's office and field sales staffs, which
together consist of approximately 800 employees, include technical and
metallurgical personnel. In addition, its technically oriented marketing
departments develop advertising materials and maintain product expertise for
each of the various types of materials sold and industries serviced by it.

Capital Expenditures

   In recent years the Company has made capital expenditures to maintain,
improve and expand processing capabilities. Additions by the Company to
property, plant and equipment, together with retirements for the five years
ended December 31, 1999, excluding the initial purchase price of acquisitions,
are set forth below. Net capital additions during such period aggregated $85.8
million.

</TABLE>

   NOTE: The above does not include capital expenditures related to
discontinued operations.

   The Company anticipates that capital expenditures, excluding acquisitions,
will be in the range of $40 million to $50 million for 2000, which it expects
will be funded from cash generated by operations.

Employees

   As of December 31, 1999, the Company employed approximately 5,050 persons,
of which approximately 2,480 were salaried employees and approximately 2,570
were hourly employees. Approximately 33% of the hourly employees were members
of various unions, including the United Steelworkers and the Teamsters, and an
additional approximately 30% of the hourly employees have voted for union
certification in proceedings currently on appeal before the Washington D.C.
Federal Circuit Court. The Company's relationship with the various unions
generally has been good and over the last five years, there have been no work
stoppages. During 2000, contracts covering approximately 100 employees at four
facilities will expire. During 2001, contracts covering approximately 100
employees at three facilities will expire. The current agreement with the
United Steelworkers will expire on July 31, 2003, and agreements with the
Teamsters expire on various dates during the period March 31, 2000 through
June 26, 2004. While management does not expect any unresolvable issues to
arise in connection with the renewal of any of these contracts, no assurances
can be given that any of these contracts will be extended prior to their
expiration.

Environmental, Health and Safety Matters

   The Company's operations are subject to many federal, state and local
regulations relating to the protection of the environment and to workplace
health and safety. In particular, its operations are subject to extensive
federal, state and local laws and regulations governing waste disposal, air
and water emissions, the handling of hazardous substances, environmental
protection, remediation, workplace exposure and other matters. The Company's
management believes that it is presently in substantial compliance with all
such laws and does not currently anticipate that it will be required to expend
any substantial amounts in the foreseeable future in order to meet current
environmental, workplace health or safety requirements. However, additional
costs and liabilities may be incurred to comply with current and future
requirements, which costs and liabilities could have a material adverse effect
on the Company's results of operations or financial condition.

   There are no known pending remedial actions or claims relating to
environmental matters that are expected to have a material effect on the
Company's financial position or results of operations. Some of the properties
owned or leased by the Company, however, are located in industrial areas or
have a history of heavy industrial use. These properties may potentially incur
environmental liabilities in the future that could have a material adverse
effect on the Company's financial condition or results of operations.

   Capital and operating expenses for pollution control projects were less
than $500,000 per year for the past five years and are expected to remain at

Corporate Restructuring

   In 1998, the Company, formerly Inland Steel Industries, Inc. ("Inland"),
sold its wholly owned subsidiary, Inland Steel Company, to Ispat
International, N.V. for approximately $1.1 billion in cash. On February 25,
1999, Inland's majority-owned subsidiary, then named Ryerson Tull, Inc. ("Pre-

wholly owned subsidiary and each share of Pre-merger Ryerson Tull Class A
common stock was converted into 0.61 shares of Inland's common stock. Pre-
merger Ryerson Tull then merged with Inland and the Company changed its name
to Ryerson Tull, Inc. These mergers are together referred to as the RT Merger.

   On January 31, 1999 Ryerson Tull purchased Washington Specialty Metals

ITEM 3. LEGAL PROCEEDINGS.

   From time to time, the Company is named as a defendant in legal actions
arising in the ordinary course of its business. The Company is a party to the
following pending legal proceedings in addition to routine litigation

                                       8
<PAGE>

incidental to its business. Management does not believe that the resolution of
these claims will have a material adverse effect on the Company's financial
condition or results of operations.

   On July 20, 1998, the Company commenced a tender offer to repurchase a
portion of its outstanding shares. On August 5, 1998, Greenway Partners, L.P.
and related parties ("Greenway") filed suit in the Delaware Chancery Court
seeking to enjoin the Company from consummating the tender offer. Greenway
alleged that given the number of shares of Common Stock that it owned, the
size of the tender offer and the terms of the Company's rights agreement,
Greenway was coerced into tendering its shares of Common Stock in the tender
offer or risk being declared an "adverse person" by the Company's Board of
Directors, triggering the separation of the rights under the Company's rights
agreement. The court denied Greenway's request for a temporary restraining
order, and Greenway tendered all of its Common Stock into the offer. Greenway
has reserved its rights to seek appropriate remedies, including rescission of
the purchase of its approximately 2.9 million shares of Common Stock or
damages. It is unclear what measure of damages the court would apply in the
case. If Greenway is successful in its suit, the Company does not anticipate
that other stockholders who participated in the tender offer will be entitled
to rescission or damages.

   On September 23, 1998, the Company issued a press release stating that it
had offered to acquire all of the outstanding publicly held shares of Pre-
merger Ryerson Tull Class A common stock in a merger transaction, pursuant to
which the Pre-merger Ryerson Tull stockholders (other than the Company and its
subsidiaries) would receive 0.54 of a share of Common Stock for each share of
Pre-merger Ryerson Tull Class A common stock (the "Proposal").

   After the September 23, 1998 public announcement of the Proposal, three
lawsuits were filed by certain Pre-merger Ryerson Tull stockholders in the
Delaware Court of Chancery against the Company, Pre-merger Ryerson Tull and
certain directors of the Company and Pre-merger Ryerson Tull. These lawsuits
are purported class actions on behalf of all Pre-merger Ryerson Tull
stockholders and allege that the Proposal was unfair and inadequate because,
among other things, the intrinsic value of the Pre-merger Ryerson Tull Class A
common stock was allegedly materially in excess of the Proposal's exchange
ratio. The lawsuits also allege that the Company breached its duty of loyalty
to Pre-merger Ryerson Tull stockholders by using its control of Pre-merger
Ryerson Tull to seek to force Pre-merger Ryerson Tull stockholders to exchange
their equity interest in Pre-merger Ryerson Tull for unfair consideration. The
lawsuits sought to enjoin consummation of the Proposal or, in the alternative,
request rescission and monetary damages.

ITEM 4. SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS.

that value. The Company has only limited involvement with derivative financial
instruments and does not use them for speculative or trading purposes. Cash
equivalents are highly liquid, short-term investments with maturities of three
months or less that are an integral part of the Company's cash management
portfolio. The carrying amount of cash equivalents approximates fair value
because of the short maturity of those instruments. The estimated fair value
of the Company's long-term debt and the portions thereof using quoted market
prices of Company debt securities recently traded and market-based prices of
similar securities for those securities not recently traded was $264 million
at December 31, 1999 and $282 million at December 31, 1998, as compared with
the carrying value of $259 million and $257 million at year-end 1999 and 1998,
respectively.
