                                  THE COMPANY
 
    United Stationers is the leading broad line wholesale distributor of
business products in North America. The Company offers more than 30,000
stockkeeping units ("SKUs"), including traditional office products, office
furniture, computer supplies, facilities management supplies and janitorial and
sanitation supplies. The Company's customer base is comprised of more than
15,000 resellers, including office products dealers, office furniture dealers,
office products superstores, mass merchandisers, computer products resellers,
mail order companies and sanitary supply distributors. United Stationers serves
its customers through an integrated nationwide network of 41 business products
distribution centers and 15 janitorial and sanitation distribution centers. In
addition to its broad product offering, the Company provides value-added
marketing and logistics services to both manufacturers and resellers. For the 12
months ended June 30, 1997, the Company had net sales of approximately $2.4
billion and operating income of approximately $123.0 million, making it the
largest broad line business products wholesaler in North America, with annual
sales of more than twice its next largest competitor.
 
    The Company estimates that the U.S. business products industry generated
sales of more than $100 billion in manufacturers' shipments in 1995 (based on
independent industry sources). In recent years, this industry has experienced
significant consolidation at all levels of the supply chain, including
manufacturers, wholesalers and resellers. During this period, the Company has
strengthened its competitive position by: (i) leveraging its significant scale;
(ii) emphasizing cost-effective operations and systems; (iii) stocking the
broadest range of business products in the industry; and (iv) providing a high
level of customer service, including quick and accurate order fulfillment and
consistent on-time and accurate order delivery. Throughout this consolidation,
the Company has successfully maintained relationships with a diverse customer
base, with no single reseller accounting for more than 6% of the Company's net
sales in 1996.
 
    As competition within the business products industry has increased,
resellers have focused on broadening their product offerings on a cost-effective
basis as well as providing high in-stock order fill rates on same day and
overnight delivery to end users. A primary goal of the Company is to be the
reseller's "wholesale partner of choice" by assisting its customers in achieving
these objectives and enabling them to increase their own profitability and
return on assets. United Stationers offers one-stop shopping to its customers by
providing a comprehensive inventory of products from more than 500
manufacturers. As the Company's product line is much larger and broader than
that which resellers can economically stock themselves, resellers can rely on
the Company to offer safety stock (inventory back-up on high volume items) and
to stock certain slower-moving, generally higher margin products. As a result of
volume purchasing, the Company often qualifies for better pricing and terms than
are available to resellers. In addition, the Company can offer significantly
lower minimum order quantities than are available to resellers directly from
manufacturers.
 
    United Stationers also provides a broad range of value-added services to
resellers. The Company produces catalogs (available in paper form, on CD-ROM and
through seamless links to the Company's web site) for its resellers to customize
and use as consumer marketing tools. For the 1997 catalog season, the Company
circulated more than 10 million broad line and specialized catalogs. The
Company's order entry systems allow resellers to place orders electronically
with the Company, thereby increasing a reseller's efficiency. Further, the
Company is able to deliver pre-sold products directly to the reseller's
customers or to the reseller for delivery to the end user without further
packaging. Through its state-of-the-art information systems and integrated
nationwide network of distribution centers, the Company has been able to achieve
a high order fill rate, which is
 
                                       3
<PAGE>
an important benefit to resellers in providing timely deliveries to end users.
All of these services are provided in such a manner that the end user has no
knowledge of the Company's role in the supply chain, as all catalogs and
packaging are customized with the name of the reseller, allowing the reseller to
maintain and foster end-user relationships. By utilizing the Company's services
and products, resellers have begun to realize the economic value of reducing the
number of SKUs they carry and are increasingly relying upon the Company for
direct order fulfillment. The Company believes that this trend of "de-stocking"
by resellers will continue.
 
    United Stationers is an integral part of the supply chain for resellers.
Additionally, manufacturers value the Company as both a cost-effective
distribution channel and as a sales outlet that provides broad geographic
exposure for their products. United Stationers also facilitates the introduction
of new products by manufacturers through the use of the Company's widely
distributed marketing materials. By serving as a distribution channel for
manufacturers, the Company assumes credit risk and cost-effectively breaks bulk
shipments into individual orders for overnight delivery, allowing manufacturers
to realize efficiencies in order administration, warehousing and freight costs.
Manufacturers also rely on the Company to reach smaller resellers who are not
large enough to purchase directly due to their small order sizes and the related
high delivery costs.
 
    United Stationers' strategy is to create value in the supply chain for both
resellers and manufacturers. By reducing the overall cost of distribution, the
Company believes its role as a wholesaler will continue to expand and that it
can achieve above industry-average growth rates by:
 
    - CAPTURING A GREATER SHARE OF EXISTING CUSTOMERS' PURCHASES.  The Company
      believes that it has the opportunity to capture a portion of the sales of
      business products currently sold directly by manufacturers to resellers
      without wholesaler involvement (currently only approximately 20% of
      manufacturers' shipments of business products move through wholesalers).
      The Company believes that as resellers intensify their focus on asset
      management, return on investment and inventory efficiency, they will
      continue de-stocking and increasingly rely on United Stationers' products
      and services to meet end-user requirements for a high order fill rate on
      an overnight basis.
 
    - EXPANDING ITS CUSTOMER BASE.  The Company plans to continue to expand its
      customer base by: (i) maintaining and building its business with
      commercial dealers and contract stationers; (ii) developing additional
      programs for marketing and buying groups; (iii) continuing to focus on
      complementary markets, including specialty dealers; and (iv) expanding
      geographically, both within the United States and, potentially,
      internationally.
 
    - OFFERING A BROADER LINE OF PRODUCTS AND SERVICES.  The Company's product
      line expansion plans include developing its newer product categories, such
      as office furniture, computer supplies and peripherals, facilities
      management supplies and janitorial and sanitation supplies and potentially
      offering new products or services. The Company also plans to continue to
      expand its line of private brand products.
 
    - CAPITALIZING ON CROSS-SELLING OPPORTUNITIES.  The Company believes that
      its various products and services are complementary and that there are
      significant opportunities to cross-sell to existing customers. By
      implementing this strategy, management believes the Company can enhance
      sales as resellers purchase a broader selection of products offered by the
      Company, thereby reducing end-user procurement costs and enhancing
      reseller profitability.
 
    - INCREASING TECHNOLOGICAL CAPABILITIES AND UTILIZING ELECTRONIC
      COMMERCE.  The Company intends to continue to invest in information
      systems enhancements and customer interfaces that management believes will
      allow it to capture a growing percentage of its customers' business. In
      addition, as the Internet becomes increasingly important as a marketing
      channel, the Company is positioned to participate in this trend with
      direct, on-line access by its resellers to its 25,000 SKU general line
      catalog.
 
    - MAKING STRATEGIC ACQUISITIONS.  The Company believes it can enhance its
      growth by continuing to make strategic acquisitions, such as the
      acquisition of Lagasse Bros., Inc. ("Lagasse") in 1996, which
      substantially increased the Company's position in the janitorial and
      sanitation supplies product category. The Company intends to target
      acquisitions that expand its customer base, increase its geographic reach

                              RECENT DEVELOPMENTS
 
    Net sales for the two months ended August 31, 1997 were up 12.5%, compared
with the same period a year ago (on an equivalent work-day basis). Management
believes that the United Parcel Service ("UPS") work stoppage had an
insignificant effect on the Company's sales during the work stoppage. Upon
commencement of the UPS work stoppage, the Company implemented its contingency
plan to use alternate delivery service providers. Management estimates that the
Company incurred approximately $0.9 million of increased delivery cost due to
the UPS work stoppage.
 
    During the third quarter of 1997, the Company reviewed a potential
acquisition opportunity. The Company subsequently determined not to proceed and
terminated discussions. Consequently, the Company has incurred an estimated $0.6
million of expenses in connection with business, accounting, tax and legal due
diligence, which will be expensed in the third quarter of 1997.
 
    In anticipation of the Offering, the Company redeemed all of its outstanding
Preferred Stock (as defined) for an aggregate of approximately $21.3 million on
September 2, 1997. See "Description of Capital Stock-- Preferred Stock."
 
    In addition, the Company is currently pursuing an Asset Backed
Securitization (the "ABS") transaction that is intended to be a
bankruptcy-remote and off-balance sheet financing, in order to reduce the
Company's cost of capital. The ABS would involve the sale of the Company's
accounts receivable and, if consummated, is expected to result in a lower
accounts receivable balance and senior revolver loan balance than is reported in
the Company's historical financial statements included herein. There can be no
assurance that the Company will consummate the ABS.

                        ANTICIPATED NONRECURRING CHARGES
 
    In connection with the acquisition of ASI in 1992 and the Merger in 1995,
certain members of management of the Company were granted Employee Stock Options
to acquire approximately 2.6 million shares of Common Stock (the "Merger
Incentive Options"). As a result of this Offering and the sale of shares by
certain of the Selling Stockholders, the Merger Incentive Options will vest and
become immediately exercisable. This event will require the Company to recognize
a nonrecurring, noncash compensation charge during the fourth quarter of 1997
based on the fair market value of the Common Stock on the date of the closing of
the Offering. Based on an assumed offering price of $34.25 per share, the
Company would recognize a charge equal to $48.1 million ($28.6 million net of
tax benefit of $19.5 million) or approximately $1.67 per share. Each $1.00
change in the fair market value of the Common Stock could result in a maximum
adjustment to such compensation expense of approximately $2.4 million ($1.4
million net of tax benefit of $1.0 million) or approximately $0.08 per share.
See "Principal and Selling Stockholders" and "Certain Transactions--Option and
Restricted Stock Awards."
 
    In addition, the Company expects to recognize a nonrecurring extraordinary
loss from early extinguishment of debt during the fourth quarter of 1997 related
to the redemption premium of $6.4 million ($3.8 million net of tax benefit of
$2.6 million) and write-off of certain related capitalized financing costs of
approximately $3.3 million ($2.0 million net of tax benefit of $1.3 million), or
an aggregate of $0.34 per share, as a result of the redemption of $50.0 million
aggregate principal amount of USSC's 12 3/4% Senior Subordinated Notes due 2005
(the "Notes") with the proceeds of this Offering. See "Use of Proceeds."
 
    Finally, the Company is currently negotiating the termination of certain
Management Agreements (as defined) in exchange for aggregate payments of
approximately $3.3 million. As a result, the Company expects to recognize a
one-time nonrecurring charge during the fourth quarter of 1997 of approximately
$3.3 million ($2.0 million net of tax benefit of $1.3 million) or approximately
$0.12 per share in connection with the termination and buy-out of such
agreements. See "Certain Transactions--Management Agreements."

                 SUMMARY CONSOLIDATED FINANCIAL AND OTHER DATA
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
    On March 30, 1995, Associated purchased 92.5% of the then-outstanding shares
of pre-Merger United Common Stock pursuant to a tender offer (the "Tender
Offer"). Immediately thereafter, Associated merged with and into United, and
ASI, a wholly owned subsidiary of Associated, merged with and into USSC, a
wholly owned subsidiary of United. Although United was the surviving corporation
in the Merger, the transaction was treated as a reverse acquisition for
accounting purposes, with Associated deemed the acquiring corporation.
Therefore, the historical income statement and other data for the year ended
December 31, 1995 reflect the financial information of Associated only for the
three months ended March 30, 1995, and the results of the Company for the nine
months ended December 31, 1995.
 
    Set forth below are (i) summary historical financial data; (ii) summary
supplemental pro forma data and the combined results of operations of United and
Associated for the period prior to the Merger; and (iii) summary pro forma data
reflecting the Offering, the use of proceeds therefrom, the redemption of all of
the Company's outstanding Series A Preferred Stock, $0.01 par value ("Series A
Preferred Stock"), and Series C Preferred Stock, $0.01 par value ("Series C
Preferred Stock" and, collectively with the Series A Preferred Stock, the
"Preferred Stock"), effected on September 2, 1997 and related transactions. The
summary supplemental pro forma data, the summary supplemental combined
historical data and pro forma data are intended for informational purposes only
and are not necessarily indicative of either financial position or results of
operations in the future, or that would have occurred had the events described
below occurred on the indicated dates as described elsewhere herein. The
following information should be read in conjunction with, and is qualified in
its entirety by, the historical Consolidated Financial Statements of the Company
and its predecessors, together with the related notes thereto, the "Unaudited
Consolidated Pro Forma Financial Statements," and related notes thereto, and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" herein.

(1) Supplemental combined historical data for the year ended December 31, 1994
    represent a combination, without pro forma adjustments, of historical
    financial data for Associated derived from its audited consolidated
    financial statements for the fiscal year ended December 31, 1994, and
    historical financial data for United derived from its unaudited consolidated
    financial statements for the twelve-month period ended December 31, 1994.
    This information is presented to facilitate a better understanding of the
    combined operations prior to the Merger.
 
(2) Supplemental pro forma data for the year ended December 31, 1995 are based
    on the audited consolidated financial statements of the Company for the
    fiscal year ended December 31, 1995 (which includes the results of
    operations of Associated for twelve months but excludes United for the three
    months ended March 30, 1995) and the unaudited consolidated financial
    statements of United for the three-month period ended March 30, 1995 giving
    effect to (i) increased depreciation expense of $1.3 million resulting from
    the write-up of certain fixed assets to fair value, (ii) additional
    incremental goodwill amortization, (iii) elimination of nonrecurring
    compensation expense of $1.5 million relating to certain employee stock
    options recognized as a result of the Merger and (iv) the elimination of
    $37.6 million in costs described in (4) below. This information is presented
    to facilitate a better understanding of the combined operations prior to the
    Merger.
 
(3) Effective January 1, 1995, Associated changed its method of accounting for
    the cost of inventory from the first-in, first-out ("FIFO") method to the
    last-in, first-out ("LIFO") method. This change resulted in the reduction of
    1995 pre-tax income of the Company of approximately $8.8 million ($5.3
    million net of tax benefit of $3.5 million). See "Management's Discussion
    and Analysis of Financial Condition and Results of Operations--General
    Information" included elsewhere herein.
 
(4) Supplemental pro forma operating expenses for the year ended December 31,
    1995 exclude the following items: (i) a restructuring charge of $9.8 million
    related to the Merger which was recorded by the Company during the year
    ended December 31, 1995; and (ii) Merger-related costs of $27.8 million
    recorded by United during the three months ended March 30, 1995.
 
(5) Restructuring charge is related to the Company's consolidation plan in
    connection with the Merger.
 
(6) Loss on early retirement of debt, net of tax benefit of $1.0 million.
 
(7) EBITDA is defined as earnings before interest, income taxes, depreciation
    and amortization. EBITDA is presented because it is a widely accepted
    financial indicator of a company's ability to incur and service debt and is
    also one of the financial measures by which certain covenants under the
    Company's Credit Agreement (as hereinafter defined) are calculated. However,
    EBITDA should not be considered in isolation or as a substitute for net
    income or cash flow data prepared in accordance with generally accepted
    accounting principles or as a measure of a company's profitability or
    liquidity. Also, the EBITDA definition used herein may not be comparable to
    similarly titled measures reported by other companies.
 
(8) EBITDA margin represents EBITDA as a percentage of net sales.
 
(9) See "Unaudited Consolidated Pro Forma Financial Statements" for a discussion
    of the adjustments used in the preparation of this data.
 
(10) Includes current maturities.

FOLLOWING MATTERS AND CERTAIN OTHER FACTORS NOTED THROUGHOUT THIS PROSPECTUS,
AND ANY EXHIBITS TO THE REGISTRATION STATEMENT OF WHICH THIS PROSPECTUS IS A
PART, CONSTITUTE CAUTIONARY STATEMENTS IDENTIFYING IMPORTANT FACTORS WITH
RESPECT TO ANY SUCH FORWARD-LOOKING STATEMENTS, INCLUDING CERTAIN RISKS AND
UNCERTAINTIES, THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM THOSE
IN SUCH FORWARD-LOOKING STATEMENTS.
 
COMPETITION
 
    The Company operates in a highly competitive environment. The Company
competes with business products manufacturers and other national, regional and
specialty wholesalers of business products, office furniture, computer products,
janitorial and sanitation supplies and related items. Some of these competitors
are larger than the Company and have greater financial and other resources
available to them than does the Company, and there can be no assurance that the
Company can continue to compete successfully with such competitors. Increased
competition in the business products industry, together with increased
advertising, has heightened price awareness among end users. Such heightened
price awareness has led to margin pressure on business products. In the event
that such a trend continues, the Company's profit margins could be adversely
affected. Further, the Company could be adversely affected by the loss of a
major customer. See "Business--Competition."
 
CONSOLIDATION
 
    Consolidation continues throughout all levels of the business products
industry. Consolidation of commercial dealers and contract stationers has
resulted in (i) an increased ability of those resellers to buy goods directly
from manufacturers on their own or through their participation in buying groups,
(ii) the ability of larger resellers who grow primarily through acquisitions to
qualify for larger volume rebates than the acquired companies would have
qualified for on a stand-alone basis, and (iii) fewer independent resellers to
purchase from wholesalers. In addition, over the last decade, office products
superstores (which largely buy directly from manufacturers) have entered
virtually every major metropolitan market. Continuing consolidation could
adversely affect the Company's financial results. See "Business--The Business
Products Industry."
 
SUBSTANTIAL LEVERAGE
 
    The Company has significant debt and debt service obligations. Assuming the
Offering and the resulting use of proceeds to redeem a portion of the
outstanding Notes (including a redemption premium thereon) and to repay
approximately $7.2 million of outstanding indebtedness under the Term Loan
Facilities (as defined) had occurred on June 30, 1997, the Company would have
had on that date (i) $482.7 million of long-term indebtedness (including current
maturities) and $197.6 million of total stockholders' equity, and (ii) long-term
indebtedness to total stockholders' equity ratio of 2.4 to 1.0. See
"Capitalization."
 
    The degree to which the Company is leveraged could have important
consequences, including the following: (i) the Company's ability to obtain
additional financing in the future for working capital, capital expenditures,
potential acquisition opportunities, general corporate purposes or other
purposes may be impaired; (ii) a substantial portion of the Company's cash flow
from operations must be dedicated to the payment of principal and interest on
its indebtedness; (iii) the Company may be more vulnerable to
 
                                       9
<PAGE>
economic downturns, may be limited in its ability to withstand competitive
pressures and may have reduced flexibility in responding to changing business
and economic conditions; and (iv) fluctuations in market interest rates will
affect the cost of the Company's borrowings to the extent not covered by
interest rate hedge agreements because interest under the Credit Facilities (as
defined) is payable at variable rates. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources" and "Description of Indebtedness."
 
ABILITY TO SERVICE DEBT
 
    The Company's ability to service its indebtedness will be dependent on its
future performance, which will be affected by prevailing economic conditions and
financial, business and other factors, certain of which are beyond the Company's
control. The Company believes that, based upon current levels of operations, it
should be able to meet its debt service obligations when due. If, however, the
Company were unable to service its indebtedness, it would be forced to pursue
one or more alternative strategies such as selling assets, restructuring or
refinancing its indebtedness or seeking additional equity capital (which may
substantially dilute the ownership interest of holders of Common Stock). There
can be no assurance that any of these strategies could be effected on
satisfactory terms, if at all. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources"
and "Description of Indebtedness."
 
RESTRICTIONS IMPOSED BY TERMS OF INDEBTEDNESS
 
    The Indenture (as amended, the "Indenture") governing the Notes of USSC and
the credit agreement governing the Company's senior secured credit facilities
(as amended, the "Credit Agreement") contain numerous restrictive covenants that
limit the discretion of management with respect to certain business matters.
These covenants place significant restrictions on, among other things, the
ability of the Company to incur additional indebtedness, to create liens or
other encumbrances, to make certain payments, investments, loans and guarantees
and to sell or otherwise dispose of assets and merge or consolidate with another
entity. The Credit Agreement also contains a number of financial covenants that
require the Company to meet certain financial ratios and tests. A failure to
comply with the obligations in the Credit Agreement or the Indenture could
result in an event of default under the Credit Agreement, or an event of default
under the Indenture, which, if not cured or waived, could permit acceleration of
the indebtedness thereunder and acceleration of indebtedness under other
instruments that may contain cross-acceleration or cross-default provisions, any
of which could have a material adverse effect on the financial condition of the
Company. In addition, the Company is a holding company which has no significant
assets other than the capital stock of USSC, and therefore, relies on dividends
and distributions from USSC as its sole source of cash. The right of the Company
to participate in dividends or other distributions from USSC are subject to
restrictions by the Indenture and the Credit Agreement, as well as the prior
rights of creditors of USSC and other statutory restrictions. See "Description
of Indebtedness."
 
CHANGING END-USER DEMANDS AND SEASONALITY
 
    The Company's sales and profitability are largely dependent on its ability
to continually enhance its product offerings in order to meet changing end-user
demands. End-users traditional demands for business products have changed over
the last several years as a result of, among other things, the widespread use of
computers and other technological advances (resulting in the reduction in use of
traditional office supplies), efforts by various businesses to establish
"paperless" work environments, increased recycling efforts and a trend toward
non-traditional offices (such as home offices). The Company's ability to
continually monitor and react to such trends and changes in end-user demands
will be necessary to avoid adverse effects on its sales and profitability. In
addition, the Company's financial results could be adversely affected if and to
the extent that end-user demand for a broad product selection or the need for
overnight
 
                                       10
<PAGE>
delivery were to diminish substantially or end-user demand for a higher
proportion of low margin products were to increase substantially.
 
    Although the Company's sales are relatively level throughout the year, the
Company's sales vary to the extent of seasonal differences in the buying
patterns of end users who purchase office products. In particular, the Company's
sales are generally higher than average during the months of January through
March when many businesses begin operating under new annual budgets. Any impact
upon sales during this peak season could have a disproportionate effect on the
Company's results of operations for the full year. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations-- Seasonality."
 
IMPACT OF CHANGING MANUFACTURERS' PRICES
 
    The Company maintains substantial inventories to accommodate the prompt
service and delivery requirements of its customers. Accordingly, the Company
purchases its products on a regular basis in an effort to maintain its inventory
at levels that it believes to be sufficient to satisfy the anticipated needs of
its customers based upon historic buying practices and market conditions.
Although the Company has historically been able to pass through manufacturers'
price increases to its customers on a timely basis, competitive conditions will
influence how much of future price increases can be passed on to the Company's
customers. Conversely, when manufacturers' prices decline, lower sales prices
could result in lower margins as the Company sells existing inventory. Changes
in the prices paid by the Company for its products therefore could have a
material effect on the Company's net sales, gross margins and net income, and
the timing of such changes throughout the year could materially impact quarterly
results.
 
EFFECT OF CHANGES IN THE ECONOMY
 
    Demand for business products is affected by, among other things, white
collar employment levels. Changes in the economy resulting in decreased white
collar employment levels may therefore adversely affect the Company's operations
and profitability. In addition, pricing and, to an extent, profitability of the
Company's product offerings, generally decrease under deflationary economic
conditions. Deflationary swings in the economy may therefore adversely affect
the Company's profitability.
 
POTENTIAL SERVICE INTERRUPTIONS
 
    Substantially all of the Company's shipping, warehouse and maintenance
employees at certain of the Company's facilities in Chicago, Detroit,
Philadelphia, Baltimore, Los Angeles, Minneapolis and New York City are covered
by various collective bargaining agreements that expire at various times during
the next three years. Although the Company considers its relations with
employees to be good, a prolonged labor dispute could have a material adverse
effect on the Company's business (including its ability to deliver its products
in a timely manner) as well as the Company's results of operations and financial
condition. Although the Company has been able to maintain its service levels
during past work stoppages by distributing to its customers from unaffected
distribution centers, profitability has been reduced during such periods as a
result of higher handling and freight costs. The Company has not experienced any
work stoppages during the past five years.
 
    The Company's ability to receive and deliver products is largely dependent
on the availability of trucking and package delivery services utilized by
manufacturers and the Company. Therefore, the occurrence of a strike or other
work stoppage by any such service provider could materially affect the Company's
sales and profitability. See "Prospectus Summary--Recent Developments."
 
DEPENDENCE ON TECHNOLOGY
 
    The Company believes that the successful operation of its business depends
to a large extent on its computerized inventory management, order processing and
distribution systems. The Company may, from
 
                                       11
<PAGE>
time to time, experience delays, complications or expenses in integrating and
operating these systems, any of which could have a material adverse effect upon
the Company's results of operations and financial condition. While the Company
believes that its computer systems will be adequate for its future needs, such
systems may require modification, improvement or replacement as the Company
grows or as technologies make these systems obsolete. For example, the Company
is currently taking steps to make all necessary modifications to its systems for
the year 2000. Anticipated expenses for these modifications are in the range of
$4.2 to $4.7 million and will be incurred during the next two years. Any such
modifications, improvements or replacements may require substantial expenditures
to design and implement and may require interruptions in operations during
periods of implementation, any of which could have a material adverse effect on
the Company's results of operations and financial condition. Further, since
approximately 90% of the Company's orders are received electronically, any
disruption of a significant reseller's computer systems could have an adverse
impact on the Company's sales. The Company's service levels also would be
affected in the event of an interruption in operation of its telecommunications
network on a company-wide scale for an extended period of time, although the
Company has developed contingency plans to limit its exposure to such risks.
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's success relies on the efforts and abilities of its executive
officers and certain other key employees, particularly Mr. Frederick B. Hegi,
Jr., the Company's non-executive Chairman of the Board, Mr. Randall W.
Larrimore, President and Chief Executive Officer, Mr. Daniel H. Bushell, an
Executive Vice President and the Chief Financial Officer of the Company, and Mr.
Michael D. Rowsey and Mr. Steven R. Schwarz, each an Executive Vice President of
the Company. The loss of any of these individuals could have a material adverse
effect on the Company. The Company has entered into employment agreements with
the executive officers listed above. The Company currently does not have any
"key man" life insurance for its key personnel. See "Management."
 
BENEFITS TO PRINCIPAL STOCKHOLDERS AND MANAGEMENT
 
    Wingate Partners, L.P. ("Wingate Partners"), Wingate Partners II, L.P.
("Wingate II"), Wingate Affiliates, L.P. ("Wingate Affiliates") and Wingate
Affiliates II, L.P. ("Wingate Affiliates II" and, collectively with Wingate
Partners, Wingate II and Wingate Affiliates, "Wingate") will receive an
estimated $39.1 million in net proceeds from the sale of an aggregate of
1,202,166 shares of Common Stock offered hereby ($45.8 million if the
Underwriters' over-allotment option is exercised in full). Mr. Hegi, the
Company's Chairman of the Board, is an indirect general partner of Wingate
Partners and Wingate II and a general partner of Wingate Affiliates and Wingate
Affiliates II. In addition, several other Selling Stockholders presently serve
as directors and/or executive officers of the Company (or formerly served as
directors and/or executive officers of Associated). See "Certain
Transactions--Interests of Certain Selling Stockholders" and "Principal and
Selling Stockholders." Furthermore, the consummation of the Offering will cause
the Merger Incentive Options held by management of the Company to vest and
become immediately exercisable. The Company will recognize a non-recurring,
non-cash compensation charge in connection with such event. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--General Information--Employee Stock Options" and "Certain
Transactions-- Option and Restricted Stock Awards."
 
INFLUENCE OF CERTAIN STOCKHOLDERS
 
    As of the date of this Prospectus and after giving effect to the Offering,
Wingate, Cumberland Capital Corporation ("Cumberland") and its affiliates, and
Mr. Daniel J. Good and his affiliates will beneficially own approximately 33.4%,
10.0% and 0.9%, respectively, of the outstanding shares of Common Stock (29.9%,
8.9% and 0.7%, respectively, if the Underwriters' over-allotment option is
exercised in full). Two of the current seven directors of the Company are
affiliates of Wingate Partners or Wingate II. In addition,
 
                                       12
<PAGE>
Mr. Gary G. Miller, who is the President and a stockholder of Cumberland, and
Mr. Good each serve as directors of the Company. Consequently, such persons and
their affiliates will continue to have significant influence over the policies
of the Company and any matters submitted to a stockholder vote. See
"Management--Directors and Executive Officers," "Certain Transactions" and
"Principal and Selling Stockholders."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
    Currently, there are approximately 3.1 million publicly held shares of
Common Stock. As a result of this relatively small number of publicly held
shares, the market price for Common Stock has varied significantly and may be
volatile depending on news announcements and changes in general market
conditions. See "Common Stock Price Range and Dividend Policy."
 
IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE
 
    Future sales by existing stockholders could adversely affect the prevailing
market price of the Common Stock. Upon completion of this Offering, the Company
will have 14,456,755 shares of Common Stock outstanding, and 758,994 shares of
Nonvoting Common Stock outstanding. In addition, 399,175 shares will be issuable
upon exercise of outstanding Warrants, and 2,631,768 shares will be issuable
upon exercise of outstanding Employee Stock Options. Of the shares of Common
Stock that will be outstanding after this Offering, approximately 7,140,828
shares (not including 392,183 shares issuable upon exercise of outstanding
Lender Warrants and 758,994 shares issuable upon conversion of Nonvoting Common
Stock) will be freely tradable without restriction or further registration under
the Securities Act of 1933, as amended (the "Securities Act"). Subject to Rule
144 under the Securities Act (as currently in effect), after expiration of
certain lock-up agreements between the Underwriters and the Company and certain
of its officers and directors and stockholders (or earlier with the consent of
the representative of the Underwriters), approximately 7,315,927 of the
remaining shares (7,064,010 shares if the Underwriters' over-allotment option is
exercised in full) will become eligible at various times for sale in the public
marketplace. In addition, certain stockholders and holders of Lender Warrants
have previously been granted registration rights entitling them to demand, in
certain circumstances, that the Company register the shares of Common Stock
and/or Lender Warrants held by them for sale under the Securities Act. In
connection therewith, the Company has effected a shelf registration with respect
to all shares of Common Stock issuable upon exercise of the Lender Warrants,
Common Stock held by Arab Banking Corporation (B.S.C.) and all shares of
Nonvoting Common Stock held by Chase Manhattan Investment Holdings, L.P.
(successor to Chase Manhattan Investment Holdings, Inc.) ("CMIH") (collectively
representing an aggregate of 392,183 shares of Common Stock and 758,994 shares
of Nonvoting Common Stock after the Offering). See "Certain
Transactions--Registration Rights Agreement." In July 1997, 173,449 Lender
Warrants were converted into Common Stock. The Company also intends to register
under the Securities Act the shares of Common Stock issuable upon exercise of
certain Employee Stock Options. Following the consummation of this Offering and
expiration of the 90-day lock-up described in "Underwriting," sales of
substantial amounts of Common Stock in the public market, pursuant to Rule 144
or otherwise, or the availability of such shares for sale, could adversely
affect the prevailing market price of the Common Stock and impair the Company's
ability to raise additional capital through the sale of equity securities. See
"Shares Eligible for Future Sale."
 
POSSIBLE ANTI-TAKEOVER EFFECTS
 
    The Company has available for issuance 1,500,000 shares of preferred stock,
which the Board of Directors is authorized to issue, in one or more series,
without any further action on the part of the Company's stockholders. At the
discretion of the Board of Directors, and subject to its fiduciary duties, the
preferred stock could be used to deter any takeover attempt, by tender offer or
otherwise. In addition, preferred stock could be issued with voting and
conversion rights which could adversely affect the voting
 
                                       13
<PAGE>
power and/or economic value to holders of Common Stock. The issuance of
preferred stock could also result in a series of securities outstanding that
would have preferences over the Common Stock with respect to dividends and in
liquidation. No shares of preferred stock are currently outstanding. See
"Description of Capital Stock--Preferred Stock."
 
    The Company's Restated Certificate of Incorporation (as amended from time to
time, the "Charter") and Restated Bylaws (as amended from time to time, the
"Bylaws") contain certain other provisions that may be deemed to have
anti-takeover effects and may delay, deter or prevent a takeover attempt that a
stockholder of the Company might consider to be in the best interests of the
Company or its stockholders. See "Description of Capital Stock--Special
Provisions of the Charter and Bylaws." In addition, the Credit Agreement
provides that the occurrence of a change of control (which term includes the
ownership by Wingate and, in certain circumstances, Good Capital (as defined)
and Cumberland and certain affiliates, of less than 2,061,580 shares of Common
Stock, or any person or group acquiring a greater number of shares of Common
Stock than Wingate) shall constitute an event of default thereunder, and the
lenders thereunder may declare all borrowings outstanding under the Credit
Agreement to become due and payable immediately, which could have a material
adverse effect on the Company and could have the effect of deterring or delaying
a takeover attempt. See "Description of Indebtedness--Credit Facilities."
Finally, the Indenture provides that, upon the occurrence of a change of control
(which term includes the acquisition by any person or group of more than 50% of
the voting power of the outstanding common stock of either United or USSC or
certain significant changes in the composition of the Board of Directors of
either United or USSC), the Company shall be obligated to offer to repurchase
all outstanding Notes at a purchase price of 101% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the date of redemption.
Such obligation, if it arose, could have a material adverse effect on the
Company and could have the effect of deterring or delaying a takeover attempt.

                                  THE COMPANY
 
    United's operating subsidiary, USSC, began operations in 1922 under the name
Utility Supply Company and has operated under its current name since 1960. In
June 1992, United acquired Stationers Distributing Company, Inc., a privately
held office products wholesaler with annual revenues of more than $400.0
million. Associated was formed in January 1992 by an investor group led by
Wingate Partners to effect the acquisition (the "Associated Transaction") of the
wholesale office products division of Boise Cascade Office Products Corporation.
To further its geographical presence and increase market share, in October 1992
Associated acquired Lynn-Edwards Corp., a privately held office products
wholesaler.
 
    On March 30, 1995, Associated purchased 92.5% of the then-outstanding shares
of pre-Merger United common stock and, immediately thereafter, Associated merged
with and into United, and ASI merged with and into USSC, with the Company and
USSC continuing as the respective surviving corporations. On October 31, 1996,
USSC acquired all of the capital stock of Lagasse, the largest wholesaler of
janitorial and sanitation supplies in the U.S. with annual sales of
approximately $80.0 million.
 
    The principal executive offices of the Company are located at 2200 East Golf
Road, Des Plaines, Illinois 60016-1267 and the telephone number is (847)
699-5000.
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from this Offering (using an assumed
offering price of $34.25 and after deducting applicable underwriting discounts
and estimated expenses payable by the Company) are estimated to be approximately
$64.6 million. Such net proceeds will be contributed to USSC to enable USSC to
(i) exercise its Equity Clawback Option (as defined under "Description of
Indebtedness-- Notes") and thereby redeem $50.0 million of the outstanding
Notes, all accrued but unpaid interest thereon and pay the redemption premium
thereon of approximately $6.4 million, and (ii) reduce by approximately $7.2
million the indebtedness under the Term Loan Facilities (as defined below) with
any remaining proceeds. The repayment of indebtedness under the Term Loan
Facilities would cause a permanent reduction of the amount borrowable
thereunder.
 
    The partial redemption of the Notes and the repayment of indebtedness under
the Term Loan Facilities described above will be effected as soon as practicable
following consummation of the Offering. Pending such redemption, the Company
will use the net proceeds allocated to such redemption to temporarily reduce
borrowings outstanding under the revolving credit facility under the Credit
Agreement (the "Revolving Credit Facility").
 
    The Notes mature on May 1, 2005, and bear interest at the rate of 12 3/4%
per annum, payable semi-annually on May 1 and November 1 of each year. See
"Description of Indebtedness" for a description of additional provisions of the
Notes and the Term Loan Facilities and the Company's use of the proceeds
therefrom.
 
    The Term Loan Facilities under the Credit Agreement (the "Term Loan
Facilities") consist of a Tranche A term loan facility (the "Tranche A
Facility") and a Tranche B term loan facility (the "Tranche B Facility"). The
Tranche A Facility bears interest at prime plus 0.25% to 1.25% or, at the
Company's option, LIBOR plus 1.50% to 2.50%. The Tranche A Facility is payable
in 20 quarterly installments, beginning on December 31, 1996, and matures on
September 30, 2001. The Tranche B Facility bears interest at prime plus 1.25% to
1.75% or, at the Company's option, LIBOR plus 2.50% to 3.00%. The Tranche B
Facility is payable in 28 quarterly installments, beginning on December 31,
1996, and matures on September 30, 2003. The Term Loan Facilities were amended
on October 31, 1996 to: (i) extend maturities; (ii) amend pricing and covenants;
and (iii) provide additional financing that was used to fund a portion of the
purchase price of Lagasse. See "Description of Indebtedness--Credit Facilities."
 
    The Company will not receive any of the proceeds from the sale of 2,000,000
shares (2,600,000 shares if the Underwriters' over-allotment option is
exercised) of Common Stock by the Selling Stockholders.

*   Due to the significant changes in the Company's capital structure resulting
    from the Merger, stock price information for periods prior to the Merger has
    not been included as it is not comparable to the stock price information
    since the Merger.
 
    On September 2, 1997, the last reported sale price of the Common Stock as
quoted on the Nasdaq National Market was $35.00 per share, and there were
approximately 1,000 holders of record of Common Stock.
 
    The Company does not currently intend to pay any cash dividends on the
Common Stock. Furthermore, as a holding company, the ability of the Company to
pay dividends in the future is dependent upon the receipt of dividends or other
payments from its operating subsidiary, USSC. The payment of dividends by USSC
to the Company for purposes of paying dividends to holders of Common Stock is
restricted by the Credit Agreement and the Indenture and is subject to statutory
restrictions. See "Risk Factors--Restrictions Imposed by Terms of Indebtedness"
and "Description of Indebtedness."

             UNAUDITED CONSOLIDATED PRO FORMA FINANCIAL STATEMENTS
 
    The following Unaudited Consolidated Pro Forma Financial Statements are
based on the historical financial statements of the Company. The pro forma
income statement gives effect to (i) the Offering (based on an assumed offering
price of $34.25) and application of the Company's net proceeds therefrom to
redeem a portion of the Notes and a portion of the Term Loan Facilities, (ii)
the exercise of certain Warrants in connection with the Offering, (iii) the
redemption of all outstanding Preferred Stock of the Company effected September
2, 1997, all as more fully described in the notes to Unaudited Consolidated Pro
Forma Financial Statements below, as if all such transactions were effected as
of the beginning of the period presented. The pro forma balance sheet is
presented giving effect to (i) the above transactions, (ii) the termination of
the put feature of the Lender Warrants, and (iii) nonrecurring charges described
below as if these transactions were effected on June 30, 1997.
 
    The pro forma income statement data excludes the following nonrecurring
charges expected to be recognized in the fourth quarter of 1997 relating to the
anticipated completion of the Offering and application of the Company's net
proceeds therefrom: (i) a noncash charge of approximately $48.1 million ($28.6
million net of tax benefit of $19.5 million) or approximately $1.67 per share in
compensation expense arising because certain Merger Incentive Options will
become exercisable upon the occurrence of a Vesting Event, and (ii) an
extraordinary loss from early extinguishment of debt during the fourth quarter
of 1997 related to the redemption premium of $6.4 million ($3.8 million net of
tax benefit of $2.6 million) and write-off of certain capitalized financing
costs of approximately $3.3 million ($2.0 million net of tax benefit of $1.3
million), or an aggregate of $0.34 per share, as a result of the redemption of
$50 million aggregate principal amount of Notes with the proceeds of this
Offering. The compensation expense described in (i) above is based on options
outstanding at June 30, 1997 and an assumed offering price of $34.25. Each $1.00
change in the fair market value of the Common Stock could result in a maximum
adjustment to such compensation expense of approximately $2.4 million ($1.4
million net of tax benefit of $1.0 million) or approximately $.08 per share. See
"Certain Transactions--Option and Restricted Stock Awards," "--Interests of
Certain Persons in the Offering," and Note 9 to the Consolidated Financial
Statements of the Company included elsewhere herein. For pro forma balance sheet
purposes, these nonrecurring charges have been reflected as a reduction of
retained earnings.
 
    The Unaudited Consolidated Pro Forma Financial Statements are intended for
informational purposes only and are not necessarily indicative of the future
financial position or future results of operations of the Company after the
Offering, or of the financial position or results of operations of the Company
that would have actually occurred had the Offering and the application of the
Company's net proceeds therefrom as described in this Prospectus and the
exercise of certain Warrants and conversion of shares of Nonvoting Common Stock
into shares of Common Stock by certain Selling Stockholders in connection with
the Offering occurred on the date or at the beginning of the period presented.
The Unaudited Consolidated Pro Forma Financial Statements and the accompanying
notes should be read in conjunction with, and are qualified in their entirety
by, the Consolidated Financial Statements of the Company, together with the
related notes thereto, included elsewhere herein.

- ------------------------
 
(1) EBITDA is defined as earnings before interest, income taxes, depreciation
    and amortization. EBITDA is presented because it is a widely accepted
    financial indicator of a company's ability to incur and service debt and is
    also one of the financial measures by which certain covenants under the
    Company's Credit Agreement are measured. However, EBITDA should not be
    considered in isolation or as a substitute for net income or cash flow data
    prepared in accordance with generally accepted accounting principles or as a
    measure of a company's profitability or liquidity. Also, the EBITDA
    definition used herein may not be comparable to similarly titled measures
    reported by other companies.
 
(2) EBITDA margin represents EBITDA as a percentage of net sales.

         NOTES TO UNAUDITED CONSOLIDATED PRO FORMA FINANCIAL STATEMENTS
 
    The pro forma financial statements have been prepared giving effect to the
following:
 
    (1) The offering price for the shares of Common Stock is assumed to be
       $34.25 per share.
 
    (2) The Pro Forma Balance Sheet reflects a noncash charge of approximately
       $50.4 million ($30.0 million net of tax benefit of $20.4 million) or
       approximately $1.75 per share in compensation expense to be recognized
       because the Merger Incentive Options will become exercisable upon
       consummation of the Offering. Such compensation expense is based on
       exercise prices and options outstanding at June 30, 1997 and an assumed
       offering price of $34.25. Each $1.00 change in the fair market value of
       the Common Stock could result in a maximum adjustment to such
       compensation expense of approximately $2.4 million ($1.4 million net of
       tax benefit of $1.0 million) or approximately $0.08 per share. See
       "Certain Transactions--Option and Restricted Stock Awards." For pro forma
       income statement purposes, this one-time nonrecurring noncash charge has
       been excluded.
 
    (3) Income taxes have been provided for pro forma adjustments at 40.5%.
 
    Pro forma adjustments have been made to the Pro Forma Balance Sheet to
    reflect the following effects of the Offering and use of proceeds therefrom
    (dollars in thousands):
 
    (a) Write-off of capitalized financing costs relating to the redemption of a
       portion of the Notes and the reduction of the Term Loan Facilities.
 
    (b) Payment of accrued interest in conjunction with redemption of a portion
       of the Notes using a portion of the proceeds of the Offering.
 
    (c) Adjustment to current income tax liability for tax effect of write-off
       of deferred financing costs and payment of redemption premium.
 
    (d) Adjustment to deferred taxes to reflect tax effect of compensation
       expense relating to Merger Incentive Options.

       with accrued and unpaid dividends thereon through June 30, 1997.

acquisition for accounting purposes, with Associated as the acquiring
corporation. Therefore, the income statement and operating and other data for
the year ended December 31, 1995 reflect the financial information of Associated
only for the three months ended March 31, 1995 and the results of the Company
for the nine months ended December 31, 1995. The balance sheet data at December
31, 1995 reflects the consolidated balances of the Company, including various
Merger-related adjustments.

31, 1993 and 1994 have been derived from the consolidated financial statements
of Associated, which have been audited by Arthur Andersen LLP, independent
public accountants. The selected consolidated financial data of the Company for

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion should be read in conjunction with the Consolidated
Financial Statements and related notes thereto appearing elsewhere herein.
 
    Certain information presented herein includes forward-looking statements
regarding the Company's future results of operations. The Company is confident
that its expectations are based on reasonable assumptions given its knowledge of
its operations and business. However, there can be no assurance that the
Company's actual results will not differ materially from its expectations. The
matters referred to in forward-looking statements may be affected by the risks
and uncertainties involved in the Company's business including, among others,
competition with business products manufacturers and other wholesalers,
consolidation of the business products industry, the ability to maintain gross
profit margins, the ability to achieve future cost savings, changing end-user
demands, changes in manufacturer pricing, service interruptions and availability
of liquidity and capital resources.
 
OVERVIEW
 
    On March 30, 1995, Associated merged with and into United. Although the
Company was the surviving corporation in the Merger, the transaction was treated
as a reverse acquisition for accounting purposes, with Associated as the
acquiring corporation. Therefore, the results of operations for the year ended
December 31, 1995 reflect the financial information of Associated only for the
three months ended March 30, 1995 and the results of the Company for the nine
months ended December 31, 1995. As a result of the Merger, the results of
operations of the Company for the year ended December 31, 1995 are not
comparable to those of previous and subsequent periods.
 
    To facilitate a meaningful comparison, the following supplemental discussion
and analysis is based on certain components of the combined historical results
of operations without any pro forma adjustments for Associated and United for
the year ended December 31, 1994 and on the pro forma results of operations for
the Company for the year ended December 31, 1995. The pro forma and combined
historical results of operations do not purport to be indicative of the results
that would have been obtained had such transactions been completed for the
period presented or that may be obtained in the future.
 
GENERAL INFORMATION
 
    GROSS PROFIT MARGINS.  In recent years, a number of factors have adversely
affected gross profit margins in the office products industry, including those
of the Company. These factors reflect the increasingly competitive nature of the
industry. Competitive pressures have increased due in part to the growth of
large resellers such as national office products superstores that have
heightened price awareness at the end-user level. The increasing price
sensitivity of end users has contributed to the decline in industrywide gross
profit margins. The Company anticipates that such pressures will continue in the
future.
 
    The Company's gross profit margins vary across product categories, so that
material changes in its product mix can impact the Company's overall margin. For
example, the gross profit margin on the Company's sales of commodity products,
including product categories that have grown over the past few years, tend to be
lower than the gross profit margins on most other product categories. While the
recent increase in sales of these types of products has adversely affected the
Company's overall gross profit margin, this increase has contributed to an
increase in total operating income. The Company expects such sales to increase
as a percentage of total sales in the future.
 
    RESTRUCTURING CHARGE.  The historical results for the twelve months ended
December 31, 1995 include a restructuring charge of $9.8 million ($5.9 million
net of tax benefit of $3.9 million). This restructuring charge includes
severance costs totaling $1.8 million. The Company's consolidation plan related
to the Merger specified that 330 distribution, sales and corporate positions,
180 of which related to pre-Merger
 
                                       26

Associated, were to be eliminated substantially within one year following the
Merger. The Company achieved its target with the related termination costs of
approximately $1.8 million charged against a reserve. The restructuring charge
also includes distribution center closing costs totaling $6.7 million and SKU
reduction costs totaling $1.3 million. The consolidation plan called for the
closing of eight redundant distribution centers, six of which related to
pre-Merger Associated, and the elimination of overlapping inventory items from
the Company's catalogs substantially within the one-year period following the
Merger. Estimated distribution center closing costs included (i) the net
occupancy costs of leased facilities after being vacated and until expiration of
each applicable lease and (ii) the losses on the sale of owned facilities and
the facilities' furniture, fixtures and equipment. Estimated SKU reduction costs
included losses on the sale of inventory items which have been discontinued
solely as a result of the Merger.
 
    EMPLOYEE STOCK OPTIONS.  In September 1995, the Board of Directors approved
an amendment to the Company's Management Equity Plan to allow for the issuance
of additional Employee Stock Options to key management employees of the Company.
The Management Equity Plan was designed to increase employee commitment through
participation in the growth and performance of the Company. Subsequently,
employee stock options exercisable for an aggregate of approximately 2.2 million
additional shares of Common Stock were granted to key management employees. Some
of such Merger Incentive Options were granted at an exercise price below the
then fair market value of the Common Stock. The exercise price of certain Merger
Incentive Options increases by $0.625 on a quarterly basis effective April 1,
1996.
 
    The Merger Incentive Options granted under the Management Equity Plan do not
vest to the employee until the occurrence of an event (a "Vesting Event") that
causes Wingate and its affiliates to have received at least a full return of
their Common Stock investment (at cost) in cash, fully tradable marketable
securities or the equivalent. A Vesting Event will cause the Company to
recognize compensation expense based upon the difference between the fair market
value of the Common Stock and the exercise prices of the Merger Incentive
Options. Based upon an assumed offering price of $34.25 and Merger Incentive
Options that will become exercisable upon the occurrence of a Vesting Event, the
Company would recognize a nonrecurring noncash charge of $48.1 million in
compensation expense ($28.6 million net of tax benefit of $19.5 million), if a
Vesting Event were to occur. Each $1.00 change in the fair market value of
Common Stock could result in a maximum adjustment to such compensation expense
of approximately $2.4 million ($1.4 million net of tax effect of $1.0 million).
See "Prospectus Summary-- Anticipated Nonrecurring Charges."
 
    CHANGE IN ACCOUNTING METHOD.  Effective January 1, 1995, Associated changed
its method of accounting for the cost of inventory from the FIFO method to the
LIFO method. Associated made this change in contemplation of its acquisition of
United (accounted for as a reverse acquisition) so that its method would conform
to that of United. Associated believed that the LIFO method provided a better
matching of current costs and current revenues, and that earnings reported under
the LIFO method were more easily compared to that of other companies in the
wholesale industry where the LIFO method is common. In 1995, this change
resulted in the reduction of pre-tax income of the Company of approximately $8.8
million ($5.3 million net of tax benefit of $3.5 million). See Note 3
(Inventories) to the Consolidated Financial Statements of the Company included
elsewhere herein.
 
    RECLASSIFICATION OF DELIVERY AND OCCUPANCY COSTS.  During the fourth quarter
of 1996, the Company reclassified its delivery and occupancy costs from
operating expenses to cost of goods sold to conform the Company's presentation
to others in the business products industry. See Note 3 (Reclassification) to
the Consolidated Financial Statements included elsewhere herein.

that this combined historical financial data, when read in conjunction with the
separate historical financial statements of Associated and United prepared in
accordance with generally accepted accounting principles and included elsewhere
herein, may be helpful in understanding the past operations of the companies
that were combined in the Merger. This combined historical financial data for
1994 represents a combination of the historical financial data for Associated
and United for the periods indicated without any pro forma adjustments, and is

</TABLE>
 
COMPARISON OF HISTORICAL RESULTS FOR THE FISCAL YEAR ENDED DECEMBER 31, 1996 AND
  PRO FORMA RESULTS FOR THE FISCAL YEAR ENDED DECEMBER 31, 1995
 
    NET SALES.  Net sales increased 4.4% to $2,298.2 million for 1996 from
$2,201.9 million for 1995. This increase was primarily the result of higher unit
sales in all product categories. In addition, the Micro United division of the
Company continued to report strong growth resulting from the underlying strength
in the marketplace. The Company's year-long focus on improving the consistency
and reliability of its service has led to increased sales and higher customer
and consumer satisfaction.
 
    GROSS MARGIN.  Gross margin declined to 17.0% in 1996 from 17.3% in 1995.
This decrease reflected a shift in the Company's product mix, the continuing
consolidation of the Company's dealer base and deflation across the Company's
product mix.
 
    OPERATING EXPENSES.  Operating expenses decreased as a percentage of net
sales to 12.1% in 1996, compared with 13.6% in 1995. This decrease was primarily
due to the realization of Merger synergies, cost containment, productivity
improvements and leveraging of fixed expenses.
 
    INCOME FROM OPERATIONS.  Income from operations as a percentage of net sales
increased to 4.9% in 1996 from 3.7% in 1995.
 
COMPARISON OF PRO FORMA RESULTS FOR THE FISCAL YEAR ENDED DECEMBER 31, 1995 AND
  COMBINED RESULTS FOR THE FISCAL YEAR ENDED DECEMBER 31, 1994
 
    NET SALES.  Net sales were $2,201.9 million for 1995, a 10.6% increase over
net sales of $1,990.4 million in 1994. The increase in net sales was primarily
the result of changes in unit volume rather than changes in prices. Sales grew
in all geographic regions. In addition, the sales growth was attributable to an
increase in the sale of computer-related products through the Company's Micro
United division.
 
                                       28
<PAGE>
    GROSS MARGIN.  Gross profit as a percentage of net sales was 17.3% in both
1995 and 1994. The gross profit margin in 1995 reflects a shift in product mix
and a larger LIFO charge due to Associated's change in its method of accounting
for inventory from the FIFO method to the LIFO method. Also, gross profit was
adversely affected in 1995 by higher sales of computer-related products and
commodity items which typically carry lower gross profit margins, offset by
lower freight and occupancy costs.
 
    OPERATING EXPENSES.  Operating expenses as a percentage of net sales
decreased to 13.6% in 1995 from 14.3% in 1994. The decrease in operating
expenses as a percentage of net sales was primarily due to increased operating
efficiencies, improved productivity and increased economies of scale as a result
of a higher sales base.
 
    INCOME FROM OPERATIONS.  Income from operations as a percentage of net sales
was 3.7% in 1995 compared with 3.0% in 1994.
 
HISTORICAL RESULTS OF OPERATIONS
 
COMPARISON OF THE HISTORICAL RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE
  30, 1997 AND 1996
 
    NET SALES.  Net sales were $1,245.1 million in the first six months of 1997,
a 10.9% increase over net sales of $1,122.6 million in the first six months of
1996. On an equivalent workday basis, sales were up 11.8% from the comparable
prior-year first six months. This included incremental growth resulting from the
Lagasse acquisition. The Company is experiencing sales strength within all
product segments and geographic regions.
 
    GROSS MARGIN.  Gross margin as a percentage of net sales increased to 17.2%
in the first six months of 1997 from 16.9% in the comparable period of 1996. The
increase reflected the favorable impact of inventory investment purchases and
lower delivery costs as a percentage of net sales.
 
    OPERATING EXPENSES.  Operating expenses as a percentage of net sales
declined to 12.1% in the first six months of 1997 from 12.2% in the first six
months of 1996. The decline in operating expenses as a percentage of net sales
was primarily the result of improved productivity and the leveraging of fixed
expenses on a higher sales base. However, the 1997 results were impacted by
incremental expenses related to the use of outside consultants to facilitate
additional systems enhancements and to accelerate the Company's strategic
planning process. These were planned expenditures which are expected to
contribute to the Company's long-term growth and profitability.
 
    INCOME FROM OPERATIONS.  Income from operations as a percentage of net sales
increased to 5.1% in the first six months of 1997 from 4.7% in the first six
months of 1996.
 
    INTEREST EXPENSE.  Interest expense as a percentage of net sales was 2.3% in
the first six months of 1997, compared with 2.6% in the comparable period in
1996. This reduction reflects the leveraging of fixed interest costs against
higher sales and lower interest rates on variable rate debt, partially offset by
interest expense on debt used to acquire Lagasse.
 
    INCOME BEFORE INCOME TAXES.  Income before income taxes as a percentage of
net sales was 2.8% in the first six months of 1997, compared with 2.1% in the
first six months of 1996.
 
    NET INCOME.  Net income before Preferred Stock dividends was $19.9 million
in the first six months of 1997, compared with $13.5 million in the first six
months of 1996.
 
COMPARISON OF HISTORICAL FISCAL YEARS ENDED DECEMBER 31, 1996 AND 1995
 
    NET SALES.  Net sales increased 31.2% to $2,298.2 million for 1996 from
$1,751.5 million for 1995. This increase was primarily the result of the Merger
for a full twelve months in 1996. Sales in 1995 include only nine months of
United's sales.
 
                                       29
<PAGE>
    GROSS MARGIN.  Gross margin declined to 17.0% in 1996 from 17.4% in 1995.
This decrease reflected a shift in the Company's product mix, the continuing
consolidation of the Company's dealer base and deflation across the Company's
product mix.
 
    OPERATING EXPENSES.  Operating expenses decreased as a percentage of net
sales to 12.1% in 1996, compared with 14.1% in 1995. The results for 1995
include the impact of a restructuring charge of $9.8 million ($5.9 million net
of tax benefit of $3.9 million). The decline in the operating expense ratio
before the restructuring charge (12.1% in 1996 versus 13.5% in 1995) was
primarily due to the realization of merger synergies, cost containment,
productivity improvements and leveraging of fixed expenses.
 
    INCOME FROM OPERATIONS.  Income from operations as a percentage of net sales
increased to 4.9% in 1996 from 3.3% in 1995.
 
    INTEREST EXPENSE.  Interest expense as a percentage of net sales was 2.5% in
1996, compared with 2.6% in 1995. This reduction reflects the leveraging of
fixed interest costs against higher sales, partially offset by funding required
to acquire Lagasse (see Note 1 to the Consolidated Financial Statements of the
Company included elsewhere herein).
 
    INCOME BEFORE INCOME TAXES AND EXTRAORDINARY ITEM.  Income before income
taxes and extraordinary item as a percentage of net sales increased to 2.4% in
1996 from 0.7% in 1995.
 
    NET INCOME.  Net income as a percentage of net sales increased to 1.4% in
1996 from 0.3% in 1995 resulting from the aforementioned reasons. Net income in
1995 includes an extraordinary item, loss on the early retirement of debt
related to the Merger of $2.4 million ($1.4 million net of tax benefit of $1.0
million) or 0.1% of net sales.
 
    FOURTH QUARTER RESULTS.  Certain expense and cost of sale estimates are
recorded throughout the year including inventory shrinkage, required LIFO
reserve, manufacturers' allowances, advertising costs and various expense items.
During the fourth quarter of 1996, the Company recorded approximately $3.0
million of additional net income relating to the refinement of estimates
recorded in the prior three quarters.
 
COMPARISON OF HISTORICAL FISCAL YEARS ENDED DECEMBER 31, 1995 AND 1994
 
    NET SALES.  Net sales were $1,751.5 million for 1995 compared with $470.2
million in 1994. The increase was primarily the result of the Merger. Sales in
1995 include nine months of United's sales.
 
    GROSS MARGIN.  Gross profit as a percentage of net sales decreased to 17.4%
in 1995 from 18.7% in 1994. The lower gross profit margin reflects a shift in
product mix, the Merger and the change in the method of accounting for inventory
from the FIFO method to the LIFO method. See Note 3 (Inventories) to the
Consolidated Financial Statements of the Company included elsewhere herein.
 
    OPERATING EXPENSES.  Operating expenses as a percentage of net sales
decreased to 14.1% in 1995 from 14.8% in 1994. The actual results for 1995
include the impact of a restructuring charge of $9.8 million ($5.9 million net
of tax benefit of $3.9 million) in the first quarter of 1995. Operating expenses
before the restructuring charge were 13.5% in 1995. The decrease in operating
expenses as a percentage of net sales before the restructuring charge was
primarily due to increased operating efficiencies and improved productivity,
partially offset by Merger-related compensation expense relating to an increase
in the value of employee stock options of approximately $1.5 million ($0.9
million net of tax benefit of $0.6 million).
 
    INCOME FROM OPERATIONS.  Income from operations as a percentage of net sales
was 3.3% in 1995 (after the restructuring charge) compared with 3.9% in 1994.
Before such restructuring charge, income from operations in 1995 was 3.9%.
 
                                       30
<PAGE>
    INTEREST EXPENSE.  Interest expense as a percentage of net sales was 2.6% in
1995 compared to 1.7% in 1994. The increase reflects additional debt needed to
consummate the Merger and higher interest rates in 1995.
 
    INCOME BEFORE INCOME TAXES AND EXTRAORDINARY ITEM.  Income before income
taxes and extraordinary item as a percentage of net sales was 0.7% in 1995
compared with 2.2% in 1994.
 
    INCOME BEFORE EXTRAORDINARY ITEM.  Income before extraordinary item was $6.2
million in 1995 compared with $6.4 million in 1994. An extraordinary item, the
loss on early retirement of debt related to the Merger of $2.4 million ($1.4
million net of tax benefit of $1.0 million), was recognized in the first quarter
of 1995.
 
    NET INCOME.  Net income was $4.8 million in 1995 compared with $6.4 million
in 1994. Net income in 1995 includes an extraordinary item, loss on the early
retirement of debt related to the Merger of $2.4 million ($1.4 million net of
tax benefit of $1.0 million) or 0.1% of net sales.
 
    FOURTH QUARTER RESULTS.  Certain interim expense and inventory estimates are
recorded throughout the year relating to shrinkage, inflation and product mix.
The results of the year-end close and physical inventory reflected a favorable
adjustment with respect to such estimates, resulting in approximately $0.9
million of additional net income, which is reflected in the fourth quarter of
1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of June 30, 1997, the credit facilities under the Credit Agreement
consisted of $174.7 million of term loan borrowings under the Term Loan
Facilities and up to $325.0 million of revolving loan borrowings under the
Revolving Credit Facility. This agreement was amended to provide funding for the
acquisition of Lagasse, to extend the maturities, to adjust the pricing and to
revise certain covenants. In addition, the Company has $150.0 million aggregate
principal amount of Notes due 2005, $29.8 million of industrial revenue bonds
and a $2.2 million mortgage outstanding. The Company expects to use the proceeds
of this Offering to redeem $50.0 million aggregate principal amount of the Notes
and any accrued but unpaid interest thereon and pay the redemption premium
thereon and to repay a portion of the Company's indebtedness under the Term Loan
Facilities. See "Use of Proceeds."
 
    The Term Loan Facilities consist of $117.8 million under the Tranche A
Facility and $56.9 million under the Tranche B Facility. Quarterly payments
under the Tranche A Facility range from $4.98 million at June 30, 1997 to $8.30
million at September 30, 2001. Quarterly payments under the Tranche B Facility
range from $0.22 million at June 30, 1997 to $6.64 million at September 30,
2003. On March 31, 1997, principal payments of $15.9 million and $7.4 million
were paid from Excess Cash Flow (as defined in the Credit Agreement) at December
31, 1996 for the Tranche A Facility and Tranche B Facility, respectively.
 
    The Revolving Credit Facility is limited to the lesser of $325.0 million or
a borrowing base equal to: 80% of Eligible Receivables (as defined in the Credit
Agreement); plus 50% of Eligible Inventory (as defined in the Credit Agreement)
(provided that no more than 60% or, during certain periods, 65% of the borrowing
base may be attributable to Eligible Inventory); plus the aggregate amount of
cover for Letter of Credit Liabilities (as defined in the Credit Agreement). In
addition, for each fiscal year, the Company must repay revolving loans so that
for a period of 30 consecutive days in each fiscal year the aggregate revolving
loans do not exceed $250.0 million. The Revolving Credit Facility matures on
October 31, 2001. As of June 30, 1997, $118.5 million remained available for
borrowing under the Revolving Credit Facility.
 
    The Term Loan Facilities and the Revolving Credit Facility are secured by
perfected first priority pledges of the stock of USSC, all of the stock of the
domestic direct and indirect subsidiaries of USSC, certain of the stock of all
of the foreign direct and indirect subsidiaries of USSC and security interests
in, and liens upon, all accounts receivable, inventory, contract rights and
certain other personal and real property of USSC and its domestic subsidiaries.
 
                                       31
<PAGE>
    The loans outstanding under the Term Loan Facilities and the Revolving
Credit Facility generally bear interest as determined within a set range with
the rate based on the ratio of total debt (excluding any undrawn amounts under
any letters of credit) to EBITDA. The Tranche A Facility and the Revolving
Credit Facility bear interest at prime plus 0.25% to 1.25% or, at the Company's
option, LIBOR plus 1.50% to 2.50%. The Tranche B Facility bears interest at
prime plus 1.25% to 1.75% or, at the Company's option, LIBOR plus 2.50% to
3.00%.
 
    The Credit Agreement contains representations and warranties, affirmative
and negative covenants and events of default customary for financings of this
type. As of June 30, 1997, the Company was in compliance with all covenants
contained in the Credit Agreement.
 
    The Credit Agreement permits capital expenditures for the Company of up to
$15.0 million for its fiscal year ending December 31, 1997, plus $6.2 million of
unused capital expenditures, approximately $7.8 million of unused Excess Cash
Flow, and $11.1 million of proceeds from the disposition of certain property,
plant and equipment from the Company's fiscal year ended December 31, 1996.
Capital expenditures will be financed from internally generated funds and
available borrowings under the Credit Agreement. The Company expects gross
capital expenditures to be approximately $12.0 million to $14.0 million in 1997.
 
    Management believes that the Company's cash on hand, anticipated funds
generated from operations and available borrowings under the Credit Agreement,
will be sufficient to meet the short-term (less than twelve months) and
long-term operating and capital needs of the Company as well as to service its
debt in accordance with its terms. There is, however, no assurance that this
will be accomplished.
 
    United is a holding company and, as a result, its primary source of funds is
cash generated from operating activities of its operating subsidiary, USSC, and
bank borrowings by USSC. The Credit Agreement and the Indenture contain
restrictions on the ability of USSC to transfer cash to United.
 
    The Company may attempt to acquire other businesses as part of its growth
strategy. The Company currently has no agreements to acquire any such
businesses. Should the Company be successful in identifying an acquisition
candidate, however, the Company may require additional financing to consummate
such a transaction. Acquisitions involve certain inherent risks and
uncertainties. Therefore, the Company can give no assurances with respect to
whether it will be successful in identifying such a business to acquire, whether
it will be able to obtain financing to complete such an acquisition or whether
the Company will be successful in operating the acquired business.
 
    In addition, the Company is currently pursuing an Asset Backed
Securitization (the "ABS") transaction that is intended to be a
bankruptcy-remote and off-balance sheet financing, in order to reduce the
Company's cost of capital. The ABS would involve the sale of the Company's
accounts receivable and, if consummated, is expected to result in a lower
accounts receivable balance and senior revolver loan balance than is reported in
the Company's historical financial statements included herein. There can be no
assurance that the Company will consummate the ABS.

COMPARISON OF HISTORICAL CASH FLOWS FOR THE SIX MONTHS ENDED JUNE 30, 1997 AND
  1996
 
    Net cash provided by operating activities during the first six months of
1997 increased to $92.9 million from $50.6 million in the comparable prior-year
period. This increase was due to higher net income, a decrease in accounts
receivable and a decrease in inventory offset by a decrease in accounts payable.
 
    Net cash used in investing activities during the first six months of 1997
was $4.5 million compared with $1.6 million provided in the first six months of
1996. The increase in cash used was due to an increase in capital investments
during 1997 and a decrease in proceeds from the sale of property, plant and
equipment.
 
    Net cash used in financing activities during the first six months of 1997
was $80.8 million compared with $52.8 million in the first six months of 1996.
This increase was due to the required payment of $23.3 million paid from Excess
Cash Flow (as defined in the Credit Agreement) in 1997, compared with $9.0
million in 1996 and the reduction of debt due to lower working capital
requirements.
 
COMPARISON OF HISTORICAL CASH FLOWS FOR THE FISCAL YEAR ENDED DECEMBER 31, 1996
  AND 1995
 
    Net cash provided by operating activities for 1996 declined to $1.6 million
from $26.3 million in 1995. This reduction was due to an increased investment in
inventory and a decrease in accrued liabilities offset by higher net income and
an increase in accounts payable. The increase in net cash provided by operating
activities of $26.3 million in 1995 from $14.1 million in 1994 was primarily the
result of the Merger.
 
    Net cash used in investing activities during 1996 was $49.9 million,
compared with $266.3 million in 1995. The decrease is due to the Merger in 1995
offset by the acquisition of Lagasse on October 31, 1996. Also, the Company
collected $11.1 million in 1996 from the successful sale of closed facilities
and related equipment. The increase in net cash used in investing activities of
$266.3 million in 1995 from $0.6 million in 1994 was primarily the result of the
Merger.
 
    Net cash provided by financing activities in 1996 was $47.2 million,
compared with $249.8 million in 1995. The decrease was due to the financing of
the Merger in 1995 offset by additional borrowings to finance the purchase of
Lagasse. The increase in net cash provided by financing activities of $249.8
million in 1995 from net cash used of $12.7 million in 1994 was also primarily
the result of the Merger.
 
INFLATION/DEFLATION AND CHANGING PRICES
 
    Inflation and deflation can have an impact on the Company's earnings. During
inflationary times, the Company generally seeks to increase prices to its
customers, thereby creating incremental gross profit resulting from the sale of
inventory purchased at lower prices. Alternatively, significant deflation may
adversely affect the Company's profitability.

YEAR 2000 MODIFICATIONS
 
    The Company is currently taking steps to make all necessary modifications to
its systems for the year 2000. Anticipated expenses for these modifications are
in the range of $4.2 million to $4.7 million and will be incurred during the
next two years.
 
SEASONALITY
 
    Although the Company's sales are relatively level throughout the year, the
Company's sales vary to the extent of seasonal differences in the buying
patterns of end users who purchase office products. In particular, the Company's
sales are generally higher than average during the months of January through
March when many businesses begin operating under new annual budgets.
 
    The Company experiences seasonality in terms of its working capital needs,
with highest requirements in December through February reflecting a build up in
inventory prior to and during the peak sales period. The Company believes that
its current availability under the Revolving Credit Facility is sufficient to
satisfy such seasonal capital needs for the foreseeable future.

OVERVIEW
 
    United Stationers is the leading broad line wholesale distributor of
business products in North America. The Company offers more than 30,000 SKUs,
including traditional office products, office furniture, computer supplies,
facilities management supplies and janitorial and sanitation supplies. The
Company's customer base is comprised of more than 15,000 reseller customers,
including office products dealers, office furniture dealers, office products
superstores, mass merchandisers, computer products resellers, mail order
companies, and sanitary supply distributors. United Stationers serves its
customers through an integrated nationwide network of 41 business products
distribution centers and 15 janitorial and sanitation distribution centers. In
addition to its broad product offering, the Company provides value-added
marketing and logistics services to both manufacturers and resellers. For the 12
months ended June 30, 1997, the Company had net sales of approximately $2.4
billion and operating income of approximately $123.0 million, making it the
largest broad line business products wholesaler in North America, with annual
sales of more than twice its next largest competitor.
 
THE BUSINESS PRODUCTS INDUSTRY
 
    The Company operates in a large and fragmented industry that has been
experiencing consolidation (with sales of more than $100 billion in
manufacturers' shipments in 1995 based on independent industry sources). The
business products industry consists of several different channels by which
business products are distributed from the manufacturer to the end user,
including resellers buying through wholesalers and resellers purchasing directly
from manufacturers. Consolidation has occurred in recent years throughout all
levels of the business products industry. As a result of this consolidation, the
distinct boundaries that once clearly defined distribution channels have become
blurred. Over the last decade, office products superstores (which largely buy
directly from manufacturers) have entered virtually every major metropolitan
market. Despite the industry consolidation, no single reseller accounted for
more than 6% of the Company's net sales in 1996. The business products industry
consists principally of wholesalers, business products dealers (including
commercial, contract and retail), office products superstores, computer
resellers, office furniture dealers, sanitary supply distributors, mail order
companies and mass merchandisers, each as described in greater detail below:
 
    BUSINESS PRODUCTS WHOLESALERS.  The wholesale segment of the business
products industry consists of national, specialty and regional wholesalers. The
Company competes with one other national business products wholesaler on the
basis of breadth and depth of product offering, price and the provision of
extensive marketing and distribution services for their reseller customers.
Specialty office products wholesalers focus on limited product lines such as
computer supplies, legal supplies, writing instruments, office furniture and
facilities management supplies. Regional office products wholesalers generally
offer a broad range of office products and marketing services on a smaller and
more limited scale and within a much more limited geographic area than national
office products wholesalers.
 
    BUSINESS PRODUCTS DEALERS.  Business products dealers include commercial
dealers, contract stationers (e.g., Boise Cascade Office Products, BT Office
Products International, Corporate Express, U.S. Office Products) and the
contract stationer divisions of national office product superstores (e.g.,
Staples and Office Depot) and retail dealers. The most significant reseller
channel for office products distribution continues to be commercial dealers and
contract stationers that serve medium and large-sized business customers through
the use of catalogs and sales forces. These resellers typically stock products
in distribution centers and deliver them to customers on a next-day basis
against orders received electronically, by telephone or fax, or taken by a
salesperson while calling on a customer. Major commercial dealers and contract
stationers purchase in large quantities directly from manufacturers and rely
upon wholesalers for safety stock and certain slower-moving generally higher
margin SKUs in order to provide product breadth and offer significant
volume-related discounts and a high level of service to their customers.
 
                                       35
<PAGE>
    Retail office products dealers typically serve small and medium-sized
businesses, home offices and individuals. For many years, retail dealers
consisted principally of a large number of independent dealers, operating one or
a few relatively small stores in a single local area. During the last decade,
however, the office products retail market has undergone significant change,
including the elimination or consolidation of many retail dealers (including
most traditional stationery stores), as a result of the emergence and rapid
growth of discount office supply retailers, which are known as superstores. To
compete with the lower prices generally offered on commodity products by
superstores, many independent retail dealers have joined marketing or buying
groups to negotiate on a collective basis directly with manufacturers and
wholesalers, or have altered their business strategies to adapt to lower gross
margins and reduce their operating expenses.
 
    OFFICE PRODUCTS SUPERSTORES.  Office products superstores (e.g., Office
Depot, OfficeMax, Staples) employ a warehouse format, are typically open for
business seven days a week, stock a select number of items in inventory
(typically in the range of 5,000 to 7,000 products), purchase in volume,
typically take delivery at their stores directly from manufacturers and offer
many of their products at discounts from manufacturers' suggested list prices.
Virtually every major metropolitan area in the United States is now served by at
least one, and most by more than one, office products superstore. Office
products superstores may also purchase from wholesalers for "fill-in" needs and
to fill customer orders from special wholesaler catalogs made available to end
users in certain superstores when the superstore does not carry an item. This
allows the office products superstores to expand the range of products offered
without increasing their inventory levels.
 
    COMPUTER RESELLERS.  Because computer supplies are now widely used in
offices, more business products are computer related and, therefore, are sold
through computer resellers (e.g., Computer Discount Warehouse, CompUSA). In
addition, most computer resellers now offer a limited selection of more
traditional office products.
 
    OFFICE FURNITURE DEALERS.  Office furniture is a major product category
within the business products industry. Although nearly all broad line office
products dealers sell office furniture, approximately 75% of all new office
furniture is sold through office furniture dealers.
 
    SANITARY SUPPLY DISTRIBUTORS.  This customer class is now included in the
business products industry as wholesalers have expanded their product offerings
to include janitorial and sanitation supplies.
 
    MAIL ORDER COMPANIES.  Mail order marketers of office products (e.g., Quill,
Reliable Office Products, Viking Office Products) typically serve small and
medium-sized business customers and home offices. While their procurement and
order fulfillment functions are similar to contract stationers, they rely
exclusively on catalogs and other database marketing programs, rather than
direct sales forces, to sell their product offerings. Their operations are based
upon large, proprietary customer data bases and sophisticated circulation
strategies drawn from end-user marketing programs. Mail order companies purchase
from both wholesalers and manufacturers.
 
    MASS MERCHANDISERS.  The mass market retailers (e.g., Kmart, Price/Costco,
Sears, Target, Wal-Mart Stores/Sam's Club) have recently taken a growing
interest in business products. Office supplies is one of many categories of
products typically available in these stores. Certain of these retailers rely on
wholesalers to fulfill a portion of their customers' orders.
 
COMPETITIVE STRENGTHS
 
    During the last several years, the Company has strengthened its competitive
position in the business products industry through the following:
 
    SIGNIFICANT SCALE.  As the largest broad line business products wholesaler
in North America, the Company qualifies for substantial volume allowances and
can realize significant economies of scale. In
 
                                       36
<PAGE>
addition, the Company's size and nationwide service and distribution
capabilities enable it to: (i) service the demands of large national, regional,
local and individual reseller accounts by offering products from over 500
manufacturers; (ii) seek cost-effective sourcing of products both in North
America and internationally; and (iii) mitigate the effect of local or regional
economic downturns.
 
    COST EFFECTIVE OPERATIONS.  The Company seeks cost reductions at both the
corporate and operating levels in order to improve its efficiency. Examples of
such cost reduction efforts include: (i) reduced merchandise procurement and
handling costs through higher manufacturers' incentives and better terms; (ii)
continued efforts to increase inventory efficiency without lowering order fill
rates; (iii) reduced payroll and benefits costs through improved labor
allocation and higher productivity; (iv) reduced freight costs through ongoing
refinements to delivery systems; (v) increased sourcing of certain products from
lower cost sources; (vi) streamlining of work practices and procedures; and
(vii) increased leveraging of fixed costs over an increasing sales base.
 
    BROAD PRODUCT SELECTION.  Stocking over 30,000 SKUs, the Company offers the
broadest selection of business products in the industry, providing resellers
with one-stop shopping for their business products needs. The Company's size
allows it to maintain a broad product selection, thereby enabling its customers
to hold less inventory while still providing end users with a high level of
service.
 
    HIGH LEVEL OF CUSTOMER SERVICE.  The Company believes that a key component
of its success has been its focus on customer service and support. Customer
service includes: ease of ordering, rapid access to information, high order fill
rates, on-time accurate shipments and value-added management and marketing
assistance. The Company's integrated computer information system serves an
important role in providing a high level of customer service, as it allows the
Company to provide resellers with the ability to manage electronically critical
business functions, including order entry, purchasing, pricing, accounts
receivable, accounts payable and inventory control. This integrated computer
system also is designed, in part, to enable the Company to monitor five key
measures of customer satisfaction: order fill rate, order accuracy, inventory
accuracy, on-time delivery and accessibility of the Company's personnel to
customers. The Company also supports resellers' marketing efforts by designing
informative, user-friendly catalogs and other marketing materials.
 
    The Company continues to introduce additional services, such as its "wrap
and label" program that offers resellers the option to receive prepackaged
orders customized (and labeled with the reseller's name) to meet the
specifications of particular end users. The Company can also drop ship orders
directly to end users on behalf of resellers. These services allow resellers to
lower their inventory investment and minimize handling costs.
 
STRATEGY
 
    United Stationers' strategy is to create value in the supply chain for both
resellers and manufacturers. By reducing the overall cost of distribution, the
Company believes its role as a wholesaler will continue to grow and that it can
achieve above industry average growth rates by:
 
    CAPTURING A GREATER SHARE OF EXISTING CUSTOMERS' PURCHASES.  The Company
believes that it has the opportunity to capture a portion of the sales of
business products currently sold directly by manufacturers to resellers and end
users without wholesaler involvement. The Company estimates that only
approximately 20% of business products sales are made through wholesale
distributors and that approximately 80% are made directly from manufacturers to
resellers. As resellers intensify their focus on asset management and return on
investment, the Company believes that they will increasingly rely on the
Company's value-added marketing and logistics services to meet end-user
requirements for a high and accurate order fill rate on an overnight basis. The
Company also believes that the focus by resellers on inventory efficiency
leading to de-stocking will continue in the foreseeable future, creating an
opportunity
 
                                       37
<PAGE>
to capture a greater percentage of the resellers' purchases. Further, the
Company believes that manufacturers support this shift to wholesaler involvement
for products that are ordered in less-than-case quantities because of the
relatively high handling costs of such orders.
 
    EXPANDING ITS CUSTOMER BASE.  The Company plans to continue to expand its
customer base by: (i) maintaining and building its business with commercial
dealers and contract stationers (including the contract stationer divisions of
national office products superstores) who, through consolidation, have continued
to increase in size; (ii) developing additional programs for marketing and
buying groups that represent groups of dealers; (iii) continuing to focus on
complementary markets, including specialty dealers (e.g., furniture, computer
and janitorial and sanitation supply distributors); and (iv) expanding
geographically, and including potentially into international markets.
 
    OFFERING A BROADER LINE OF PRODUCTS AND SERVICES.  While United Stationers
carries the broadest product line in the industry, it continues to enhance its
product and service offerings to meet changing end-user demands. The Company's
product line expansion plans include developing its newer product categories,
such as office furniture, computer supplies and peripherals, facilities
management supplies and janitorial and sanitation supplies and potentially
offering new products and services. The Company believes that these product
categories will allow it to make additional sales to existing reseller customers
and thereby strengthen its position with such resellers as a one-stop shopping
experience. Such products also allow the Company to enter into new distribution
channels and add new types of resellers beyond broad line office products
dealers, expanding its customer base.
 
    The Company also continues to expand its line of private brand products,
including approximately 1,200 products under the Universal-TM- brand name.
Private brand products represented approximately 10% of the Company's net sales
in 1996. The Company believes its private brand products offer significant
benefits both to resellers, by providing an alternative to brand name products
that offers similar quality at a moderate price, and to manufacturers, by
enabling the manufacturer to increase sales without diluting its brand name
pricing structure. To further develop the Universal-TM- brand, the Company
operates a trading office in Hong Kong to facilitate the global purchasing of
products.
 
    CAPITALIZING ON CROSS-SELLING OPPORTUNITIES.  Historically, the Company has
marketed its business products and services primarily to office products
resellers, including commercial dealers, contract stationers, retail dealers and
office products superstores. As the Company has expanded into new product lines
(e.g., janitorial and sanitation supplies), its sales efforts have been focused
primarily on traditional distributors of these specialty products. Although the
Company will continue to utilize these marketing channels as its primary method
of product distribution, the Company believes that its various products and
services are complementary and that significant opportunities exist to
cross-sell to its existing customer base. It is the Company's goal to become
known among its customers not just as an office products distributor, but as a
distributor of a broad range of products and services for the office. Management
believes that by implementing this strategy, the Company can enhance sales to
its existing customer base as resellers purchase a broader selection of products
offered by the Company, thereby reducing procurement cost and enhancing reseller
profitability.
 
    INCREASING TECHNOLOGICAL CAPABILITIES AND PARTICIPATING IN ELECTRONIC
COMMERCE.  The Company intends to continue to invest in systems enhancements as
well as customer interfaces to make its systems more user friendly. Increased
electronic linkages for transactions with customers and suppliers enable both
the Company and its business partners to reduce their costs and execute
transactions faster and more accurately. In 1996, approximately 90% of the
Company's orders were received electronically. As the Company increases the
functionality of its proprietary systems, the Company believes it will be able
to garner a growing percentage of its customers' business.
 
    As the Internet becomes increasingly important as a marketing channel, the
Company is positioned to participate in this trend. The Company currently
provides resellers with access to its 25,000 SKU general
 
                                       38
<PAGE>
line catalog, online through seamless links to its web site. This service allows
resellers to place orders electronically with the Company for overnight delivery
as well as to provide a hot link on their own web site to the Company's general
line catalog for use by end users.
 
    MAKING STRATEGIC ACQUISITIONS.  The Company believes it can enhance its
growth by continuing to make strategic acquisitions that would allow the Company
to expand its customer base and broaden its product line. This growth strategy
has already proved to be successful for the Company with the acquisition of
Lagasse in 1996. Potential areas for acquisition include existing product
categories in which the Company now operates (such as, office furniture,
computer supplies and peripherals, facilities management supplies and janitorial
and sanitation supplies). The Company also would consider acquisition
opportunities in new areas that allow it to create additional value for its
customers and end users.
 
PRODUCTS
 
    The Company's current product offerings, comprised of more than 30,000 SKUs,
may be divided into five primary categories:
 
    TRADITIONAL OFFICE PRODUCTS.  The Company's core business continues to be
traditional office products, which includes both brand-name products and the
Company's private brand products. Traditional office products include writing
instruments, paper products, organizers and calendars and various office
accessories. The Company's traditional office product offerings are quite deep,
including, for example, more than 1,000 different SKUs of ring binders and 800
types of file folders.
 
    COMPUTERS AND RELATED SUPPLIES.  The Company offers computer supplies,
peripherals and hardware with major brand names to computer resellers and office
products dealers. These products constituted approximately 25% of the Company's
1996 net sales.
 
    OFFICE FURNITURE.  The Company's sale of office furniture such as leather
chairs, wooden and steel desks and computer furniture has enabled it to become
the nation's largest office furniture wholesaler, with the Company currently
offering nearly 3,000 furniture items from 70 different manufacturers. Office
furniture constituted approximately 14% of the Company's 1996 net sales. The
Company's "Pro-Image" consulting program enables resellers with no previous
expertise to provide high-end furniture and office design services to end users.
The Company offers national delivery and product "set-up" capabilities to
support office products dealers as well as to attract new furniture dealers.
 
    JANITORIAL AND SANITATION SUPPLIES.  The Company's dedicated marketing
effort for janitorial and sanitation supplies was created in 1993 with the
development of United Facility Supply. In October 1996, the Company acquired
Lagasse, the largest pure wholesaler of janitorial and sanitation supplies in
North America. The Company currently distributes these products through 15
Lagasse distribution centers.
 
    OTHER PRODUCTS.  The Company's newest product categories encompass
facilities management supplies, specialty mailroom and warehouse items, kitchen
and cafeteria items, first aid products and ergonomic products designed to
enhance worker productivity, comfort and safety. Another one of the Company's
niche markets is business presentation products, including audio visual
equipment, flip charts and dry erase boards. Additionally, the Company offers
its "Signature Image" program, which provides resellers with access into the
advertising specialties market (such as imprinted and logo items).
 
PURCHASING AND MERCHANDISING
 
    As the largest business products wholesaler in North America, the Company
qualifies for substantial volume allowances and can realize significant
economies of scale. The Company obtains products from over 500 manufacturers,
for many of whom the Company believes it is a significant customer. In 1996, no
supplier accounted for more than 15% of the Company's aggregate purchases. As a
centralized corporate function, the Company's merchandising department
interviews and selects suppliers and products for
 
                                       39
<PAGE>
inclusion in the catalogs. Selection is based upon end-user acceptance and
demand for the product and the manufacturer's total service, price and product
quality offering.
 
CUSTOMERS
 
    The Company sells principally to resellers of office products, consisting
primarily of commercial dealers and contract stationers, retail dealers,
superstores, mail order companies and mass merchandisers. In addition, the
Company sells to office furniture dealers, computer resellers and janitorial and
sanitary supply distributors. No single reseller accounted for more than 6% of
the Company's net sales in 1996.
 
    Commercial dealers and contract stationers are the most significant reseller
channel for office products distribution and typically serve large businesses,
institutions and government agencies. Through industry consolidation, the number
of such dealers has decreased, with the remaining dealers growing larger. As a
result, net sales to these commercial dealers and contract stationers as a group
have grown rapidly.
 
    The number of retail dealers has been declining for some time as the result
of individual retail dealers' inability to compete successfully with the growing
number of superstores and, more recently, as a result of dealerships being
acquired and brought under an umbrella of common ownership. To adapt to this
highly competitive environment, many retail dealers, commercial dealers and
contract stationers have joined marketing or buying groups in order to increase
purchasing leverage. The Company believes it is the leading wholesale source for
many of these groups, providing not only merchandise but also special programs
that enable these dealers to take advantage of their combined purchasing power.
 
    While the Company maintains and builds its business with commercial dealers,
contract stationers (including the contract stationer divisions of national
office product superstores) and retail dealers, it has also initiated
relationships with most major office products superstore chains. In addition,
the Company supplies inventory and other fulfillment services to the retail
operations of certain superstores, including their direct-to-business delivery
programs and to non-stocking resellers.
 
MARKETING AND CUSTOMER SUPPORT
 
    The Company concentrates its marketing efforts on providing value-added
services to resellers. The Company distributes products that are generally
available at similar prices from multiple sources, and most of its customers
purchase their products from more than one source. As a result, the Company
seeks to differentiate itself from its competitors through a broader product
offering, a higher degree of product availability, a variety of high quality
customer services and prompt distribution capabilities. In addition to
emphasizing its broad product line, extensive inventory, computer integration
and national distribution capabilities, the Company's marketing programs have
relied upon two additional major components. First, the Company produces an
extensive array of catalogs for commercial dealers, contract stationers and
retail dealers that are usually custom imprinted with each reseller's name and
sold to these resellers who, in turn, distribute the catalogs to their
customers. Second, the Company provides its resellers with a variety of dealer
support and marketing services, including business management systems,
promotional programs and pricing services. These services are designed to aid
the reseller in differentiating itself from its competitors by addressing the
steps in the end-user's procurement process.
 
    Substantially all of the Company's 30,000 SKUs are sold through its
comprehensive general line catalogs, promotional pieces and specialty catalogs
for the office products, office furniture, facilities management supplies and
other specialty markets. The Company produces the following annual catalogs:
General Line Catalog; Office Furniture Catalog featuring furniture and
accessories; Universal Catalog promoting the Company's private-brand
merchandise; Computer Products Catalog offering hardware, supplies, accessories
and furniture; Facilities and Maintenance Supplies Catalog featuring janitorial,
maintenance, food service, warehouse, mailroom supplies and products and
supplies used for meetings and presentations; and the Lagasse Catalog offering
janitorial and sanitation supplies. In addition, the
 
                                       40
<PAGE>
Company produces the following quarterly promotional catalogs: Action 2000
featuring over 1,000 high-volume commodity items, and Computer Concepts,
featuring computer supplies, peripherals, accessories and furniture. The Company
also produces separate quarterly flyers covering general office supplies, office
furniture and Universal-TM- products. The majority of the expenses related to
the production of such catalogs is borne by the Company's suppliers. Because
commercial dealers, contract stationers and retail dealers typically distribute
only one wholesaler's catalogs in order to streamline and concentrate order
entry, the Company attempts to maximize the distribution of its catalogs by
offering advertising credits to resellers, which can be used to offset the cost
of catalogs. Also, the Company offers an electronic catalog available on CD-ROM
and through the Company's web site.
 
    The Company also offers to its resellers a variety of electronic order entry
systems and business management and marketing programs that enhance the
resellers' ability to manage their businesses profitably. For instance, the
Company maintains electronic data interchange systems that link the Company to
selected resellers and interactive order systems that link the Company to
selected resellers and such resellers to the ultimate end user. In addition, the
Company's electronic order entry systems allow the reseller to forward its
customers' orders directly to the Company, resulting in the delivery of pre-sold
products to the reseller or directly to its customers. The Company estimates
that in 1996, it received approximately 90% of its orders electronically.
 
    To assist its resellers with pricing, the Company offers a matrix pricing
software program. Traditionally, many resellers have priced products on a
discount from the manufacturer's suggested retail price, but recently pricing
has shifted toward a net pricing approach, whereby the reseller sells certain
products at significant discounts, assuming that it can recapture the discounts
through the sale of other higher margin products. The Company's matrix pricing
program provides resellers with a resource to assist them in identifying the
optimum pricing mix between high and low margin items and, as a result, enables
resellers to manage their gross margins.
 
    In addition to marketing its products and services through the use of its
catalogs, the Company employs a sales force of approximately 150 salespersons.
The sales force is responsible for sales and service to resellers with which the
Company has an existing relationship, as well as for establishing new
relationships with additional resellers. The Company supplements the efforts of
its sales force through telemarketing.
 
PRODUCT DISTRIBUTION AND DELIVERY SYSTEMS
 
    The Company has a network of 41 business products regional distribution
centers located in 36 metropolitan areas in 25 states in the United States, most
of which carry the Company's full line of inventory. The Company also maintains
15 Lagasse distribution centers that carry a full line of janitorial and
sanitation supplies. The Company supplements its regional distribution centers
with 24 local distribution points throughout the United States that serve as
reshipment points for orders filled at the regional distribution centers. The
Company utilizes more than 350 trucks, substantially all of which are contracted
for by the Company, to enable direct delivery from the regional distribution
centers and local distribution points to resellers.
 
    The Company's distribution capabilities are aided by its proprietary,
computer-driven inventory locator system. If a reseller places an order for an
item that is out of stock at the Company location which usually serves the
particular reseller, the Company's system will automatically search for the item
at alternative distribution centers. If the item is available at an alternative
location, the system will automatically forward the order to that alternate
location, which will then coordinate shipping with the primary facility and, for
the majority of resellers, provide a single on-time delivery. The system
effectively provides the Company with added inventory support that enables it to
provide higher service levels to the reseller, to reduce back orders and to
minimize time spent searching for merchandise substitutes, all of which
 
                                       41

contribute to the Company's high order fill rate and efficient levels of
inventory balances. See "Risk Factors--Potential Service Interruptions."
 
    Another service offered by the Company to resellers is its "wrap and label"
program, that offers resellers the option to receive prepackaged orders
customized to meet the specifications of particular end users. For example, when
a reseller receives orders from a number of separate end users, the Company can
group and wrap the items separately by end user so that the reseller need only
deliver the package. The "wrap and label" program is attractive to resellers
because it eliminates the need to break down case shipments and to repackage the
orders before delivering them to the end user. The Company also can ship orders
directly to end users on behalf of resellers.
 
TECHNOLOGY
 
    The Company believes its management information systems, telecommunications
network and warehouse automation system, along with its participation in
electronic commerce are integral to the Company's success and have enabled the
Company to achieve one of the lowest cost structures and highest levels of
service in the industry.
 
    The Company operates one of the few fully integrated management information
systems in the industry. Order entry, fulfillment and billing, along with
inventory replenishment and accounts payable disbursement, are all automated.
The Company's management information systems are designed to process over
600,000 customer orders per day, supporting relatively short order-to-delivery
time windows. Management believes speed and accuracy are important in the highly
competitive business products industry. Over 90% of the orders received from the
Company's customers are electronic orders and over 85% of the Company's purchase
orders to its 500 suppliers are transmitted electronically.
 
    The Company also employs a sophisticated warehouse automation system. In
certain locations, computerized conveyor systems, carousels and bar-code
scanning are utilized to increase efficiency and quality. The Company
continuously enhances its warehousing operations through the use of technology
to meet the changing business environment and customer and consumer
requirements.
 
    The Company believes electronic commerce conducted over the Internet will
grow in importance in the future and has invested in developing its own
interactive web site (www.unitedstationers.com), an Intranet and software
products available to its reseller customers. Electronic product catalogs are
available both over the Internet and in CD-ROM versions.
 
    Management plans to continue to invest in technology to improve quality,
reliability and cost-effective operations. The Company believes its systems are
sufficient to meet its current needs and estimates it will spend $2.0 million in
computer-related capital improvements in 1997.
 
COMPETITION
 
    The Company competes with office products manufacturers and with other
national, regional and specialty wholesalers of office products, office
furniture, computers and related items. Competition between the Company and
manufacturers is based primarily upon net pricing, minimum order quantity and
product availability. Although manufacturers may provide lower prices to
resellers than the Company does, the Company's marketing and catalog programs,
combined with speed of delivery and its ability to offer resellers a broad line
of business products from multiple manufacturers on a "one-stop shop" basis and
with lower minimum order quantities, are important factors in enabling the
Company to compete effectively. See "--Marketing and Customer Support" and
"--Product Distribution and Delivery Systems." Manufacturers typically sell
their products through a variety of distribution channels, including wholesalers
and resellers.
 
    Competition among the Company and other wholesalers is based primarily on
breadth of product lines, availability of products, speed of delivery to
resellers, order fill rates, net pricing to resellers and the
 
                                       42
<PAGE>
quality of its marketing and other services. The Company believes it is
competitive in each of these areas. Most wholesale distributors of office
products conduct operations regionally and locally, sometimes with limited
product lines such as writing instruments or computer products. Only one other
national wholesaler carries a general line of office products.
 
    Increased competition in the office products industry, together with
increased advertising, has heightened price awareness among end users. As a
result, purchasers of commodity type office products have become extremely price
sensitive, and therefore, the Company has increased its efforts to market to
resellers the continuing advantages of its competitive strengths (as compared to
those of manufacturers and other wholesalers).
 
EMPLOYEES
 
    As of June 30, 1997, the Company employed approximately 5,000 persons.
 
    The Company considers its relations with employees to be good. Approximately
900 of the shipping, warehouse and maintenance employees at certain of the
Chicago, Detroit, Philadelphia, Baltimore, Los Angeles, Minneapolis and New York
City facilities are covered by collective bargaining agreements. The agreements
expire at various times during the next three years. The Company has not
experienced any work stoppages during the past five years. See "Risk
Factors--Potential Service Interruptions."
 
LEGAL PROCEEDINGS
 
    Although the Company is involved in legal proceedings arising in the
ordinary course of its business, the Company is not involved in any legal
proceeding that it believes will result, individually or in the aggregate, in a
material adverse effect upon the financial condition or results of operations of
the Company.
 
TRADEMARKS
 
    The trade names United Stationers, Micro United, Universal, United Facility
Supply, and others, are actively used and are significant to the Company's
business. All of these marks have been federally registered with the United
States Patent and Trademark Office.
 
PROPERTIES
 
    The Company considers its properties to be suitable and adequate for their
intended uses. These properties consist of the following:
 
    EXECUTIVE OFFICES.  The Company owns its office facility in Des Plaines,
Illinois which has approximately 135,800 square feet of office and storage
space. In September 1993, approximately 47,000 square feet of office space
located in Mount Prospect, Illinois was leased by the Company. This lease
expires in 1999, with an option to renew for two five-year terms.
 
                                       43

COMPOSITION OF THE BOARD OF DIRECTORS
 
    The Charter provides that the Board of Directors shall be divided into three
classes, each class as nearly equal in number as possible, and each term
consisting of three years. The directors currently in each class are as follows:
Class I (having terms expiring in 1999)--Messrs. Good and Johnson; Class II
(having terms expiring in 2000)--Messrs. Hegi, Miller and Rowsey; and Class III
(having terms expiring in 1998)-- Messrs. Larrimore and Spungin. See
"Description of Capital Stock--Special Provisions of the Charter and
Bylaws--Classified Board of Directors."
 
    Effective in August 1997, James T. Callier, Jr. and Jeffrey K. Hewson
resigned as directors of the Company. In an effort to add to the collective
experience and knowledge of the Company's Board of Directors, the Nominating
Committee of the Board of Directors of the Company is currently in the process
of identifying two new candidates to replace Messrs. Callier and Hewson on the
Board of Directors following completion of the Offering. Although members of the
current Board have had preliminary discussions with certain individuals that
they believe could add valuable insight and experience to the Board, no formal
invitations or nominations have been made and the Company is unable to predict
when any new members would be selected.
 
    Following the termination of certain capital Management Agreements, the
Compensation Committee of the Board of Directors expects to pay annual
directors' fees to the non-employee directors of the Company, including Messrs.
Hegi, Johnson, Miller and Good.

                              CERTAIN TRANSACTIONS
 
VOTING TRUST
 
    As of September 3, 1997, approximately 73.0% of the outstanding shares of
Common Stock were held in a voting trust (the "Voting Trust") pursuant to a
Voting Trust Agreement dated as of January 31, 1992. Messrs. Rowsey, Miller,
Good, Hegi and Johnson were elected to the Board of Directors pursuant to the
Voting Trust. The Voting Trust will terminate upon consummation of the Offering.
 
WARRANTS
 
    In connection with the Merger, the Company assumed certain Lender Warrants
and Preferred B Warrants that had been issued by Associated in connection with
the Associated Transaction in 1992. The Lender Warrants currently allow the
holders thereof to acquire an aggregate of 1,053,988 shares of Common Stock (or,
at such holder's option, shares of Nonvoting Common Stock) at an exercise price
of $0.10 per share. The Preferred B Warrants currently allow the holders thereof
to acquire an aggregate of 182,189 shares of Common Stock at an exercise price
of approximately $0.15 per share. Pursuant to a registration rights agreement
(as amended, the "Lender Registration Rights Agreement"), the holders of the
Lender Warrants have certain rights with respect to registration under the
Securities Act of the shares of Common Stock (or Nonvoting Common Stock)
issuable upon the exercise of such Lender Warrants. In October 1995, the Company
effected a shelf registration under the Securities Act of all shares of Common
Stock issuable upon exercise of the Lender Warrants. See "Description of Capital
Stock--Lender Warrants" and "--Preferred B Warrants." Certain Selling
Stockholders are holders of the Warrants. See "Principal and Selling
Stockholders."
 
REGISTRATION RIGHTS AGREEMENT
 
    In connection with the Associated Transaction, Associated entered into a
registration rights agreement (the "Stockholders' Registration Rights
Agreement") with Wingate Partners, Cumberland, ASI Partners, L.P., Good Capital
and certain other holders of Associated common stock (including Mr. Rowsey),
pursuant to which it granted to such stockholders certain rights with respect to
registration under the Securities Act of shares of Associated common stock held
by them. The Company assumed the obligation of Associated under the
Stockholders' Registration Rights Agreement in connection with the Merger, and
such agreement has been amended accordingly. Under the amended agreement, a
holder of 20% of the shares of Common Stock subject to the Stockholders'
Registration Rights Agreement can, in certain circumstances, require the Company
to effect up to three short-form and two long-form registrations of all or part
of such holder's shares of Common Stock. The Company is not required to honor
any request to register shares of Common Stock if the request is less than 300
days following the effective date of any previous registration statement filed
in connection with any such request.
 
MANAGEMENT AGREEMENTS
 
    Pursuant to certain Investment Banking Fee and Management Agreements
(collectively, the "Management Agreements") assumed by the Company in the
Merger, the Company paid to each of Wingate Partners, Cumberland and Good
Capital aggregate fees of $2.3 million, $100,000, and $100,000, respectively,
upon the consummation of the Merger. In addition, the Company has paid annual
fees for monitoring and oversight services provided by such parties pursuant to
the Management Agreements as follows: (i) Wingate Partners received annual fees
in the amount of $725,000, $603,000 and $350,000 pursuant to its agreement in
each of the fiscal years ended 1996, 1995 and 1994, respectively; (ii)
Cumberland received annual fees in the amount of $137,500, $129,000 and $75,000

$137,500, $129,000 and $75,000 pursuant to its Agreement in each of the fiscal
years ended 1996, 1995 and 1994, respectively. In addition, pursuant to the
Management
 
                                       48
<PAGE>
Agreements, each of Wingate Partners, Cumberland and Good Capital is entitled to
reimbursement for its reasonable out-of-pocket expenses and the Company has
agreed to indemnify each of them and their respective affiliates for any losses
in connection with the provision of their services under the Management
Agreements.
 
    It is currently anticipated that the Management Agreements will be
terminated in exchange for one-time payments of approximately $2.4 million,
$400,000 and $400,000 to Wingate Partners, Cumberland and Good Capital,
respectively. The Company expects to recognize a one-time nonrecurring charge
during the fourth quarter of 1997 of approximately $3.3 million ($2.0 million
net of tax benefit of $1.3 million) or approximately $0.12 per share in
connection with the termination and buy-out of such Management Agreements. See
"Prospectus Summary--Anticipated Nonrecurring Charges."
 
CERTAIN INTERESTS OF CHASE
 
    Chase Securities Inc. ("Chase Securities"), served as the initial purchaser
of the Notes and received a discount in the amount of $4.5 million in connection
with that transaction. As a result of the sale of the Notes, CMIH, an affiliate
of Chase Securities, beneficially owns (as of September 3, 1997) approximately
9.6% of the shares of Common Stock outstanding as a result of its ownership of
(i) the Lender Warrants received in connection with the Associated Transaction
that entitle CMIH to purchase 476,067 shares of Common Stock for $0.10 per
share, and (ii) 758,994 shares of Nonvoting Common Stock purchased and received
in connection with the Merger and sale of the Notes. CMIH intends to sell
certain of its Lender Warrants in connection with the Offering. See "Principal
and Selling Stockholders" and "Underwriting."
 
    Chase Securities served as financial advisor to Associated in connection
with the Merger. The Chase Manhattan Bank ("Chase Bank") is the agent and a
lender under the Credit Agreement. In addition, in connection with the Tender
Offer, Chase Securities served as dealer manager and Chase Bank served as
depository for tendered shares of Common Stock. A substantial portion of the net
proceeds from the sale of the Notes was used to repay a subordinated bridge
facility arranged by an affiliate of Chase Bank in connection with the Merger
and a portion of the remainder was used to prepay loans under the Term Loan
Facilities. In all such capacities, Chase Bank and its affiliates received an
aggregate of approximately $23.3 million in fees (although certain of such fees
were shared with other members of the lending groups) and had certain of their
expenses reimbursed. Chase Securities is also serving as one of the Underwriters
of this Offering and will receive compensation in that capacity. See
"Underwriting."
 
INTERESTS OF CERTAIN PERSONS IN THE OFFERING
 
    Wingate will receive an aggregate of $39.1 million ($45.8 million if the
Underwriters' over-allotment option is exercised in full) of the $65.1 million
($84.6 million if the Underwriters' over-allotment option is exercised in full)
in aggregate net proceeds to be received by the Selling Stockholders as a result
of the Offering. Mr. Hegi, the Company's Chairman, serves as a general partner
of various Wingate entities, including the indirect general partner of each of
Wingate Partners and Wingate II and a general partner of Wingate Affiliates and
Wingate Affiliates II. In addition, several other Selling Stockholders presently
serve as directors and/or executive officers of the Company or formerly served
as directors or executive officers of Associated. See "Principal and Selling
Stockholders." The Company will pay all expenses of the Offering, including
those attributable to the Selling Stockholders (excluding underwriting discounts
and commissions relating to shares of Common Stock and Warrants to be sold by
the Selling Stockholders).
 
REDEMPTION OF SERIES A PREFERRED STOCK
 
    As a result of the Company's redemption of all of its outstanding Series A
Preferred Stock effected on September 2, 1997, Wingate and ASI Partners, L.P.
received approximately $5.4 million and $2.1 million, respectively, in aggregate
proceeds. In addition, Mr. Rowsey, Executive Vice President and a director of
 
                                       49
<PAGE>
the Company, and Mr. Johnson, a director of the Company, received $92,166 and
$25,854, respectively, in aggregate proceeds from such redemption.
 
OPTION AND RESTRICTED STOCK AWARDS
 
    Effective May 23, 1997, the Company granted to Mr. Larrimore, the Company's
President and Chief Executive Officer, options to purchase an aggregate of
250,000 shares of Common Stock at an exercise price of $21.625 per share, the
fair market value of the Common Stock on the date of such grant. The grant of
certain of such options is subject to the approval of an amendment to the
Company's Management Equity Plan, for which the Company is currently seeking the
consent of the holders of the requisite number of shares of Common Stock as
described below. Options to purchase 150,000 of such shares vest in five equal
annual installments, beginning on the first anniversary of the date of grant,
and terminate on May 23, 2007 or earlier in the event of the termination of Mr.
Larrimore's employment. The options to purchase the remaining 100,000 of such
shares vest in five equal annual installments, beginning on the first
anniversary of the date of the grant, but only after the price of the Common
Stock has been equal to or greater than $40.00 per share for at least 80 of 100
consecutive trading days since the date of the grant (otherwise such options
become exercisable on December 31, 2006), and also terminate on May 23, 2007 or
earlier in the event of the termination of Mr. Larrimore's employment.
 
    In connection with the Associated Transaction in 1992 and the Merger in
1995, the Company has granted Merger Incentive Options to acquire approximately
2.6 million shares of Common Stock to certain members of management at exercise
prices currently ranging from $1.45 to $16.25 per share. Of such Merger
Incentive Options, the Company has granted to Messrs. Rowsey and Bushell Merger
Incentive Options exercisable for an aggregate of (i) 94,506 and 89,199 shares,
respectively, at an exercise price of $1.45 per share; (ii) 15,000 and 15,000
shares, respectively, at an exercise price of $5.12 per share; and (iii) 105,000
and 105,000 shares, respectively, at an exercise price of $12.50 per share
(subject to quarterly increases until the occurrence of a Vesting Event). The
Company has also granted Merger Incentive Options to Messrs. Schwarz and Uskup
exercisable for an aggregate of (i) 15,000 and 7,500 shares, respectively, at an
exercise price of $5.12 per share and (ii) 105,000 and 52,500 shares,
respectively, at an exercise price of $12.50 per share (subject to quarterly
increases until the occurrence of a Vesting Event). The Merger Incentive Options
do not vest until the occurrence of a Vesting Event that causes Wingate and its
affiliates to have received at least a full return of their investment (at cost)
in cash, fully tradable marketable securities, or the equivalent, as determined
by the Board of Directors of the Company in good faith. All of such Merger
Incentive Options will become exercisable upon the consummation of this
Offering. See "Prospectus Summary--Anticipated Nonrecurring Charges."
 
    On November 29, 1995, the Company granted a restricted stock award of 9,678
shares of Common Stock to Joel D. Spungin, a director of the Company, in
consideration for his service on the Board of Directors in lieu of directors'
compensation for a three-year period. Additionally, the Company granted to
Jeffrey K. Hewson, a former director of the Company, options exercisable for an
aggregate of 14,648 shares of Common Stock at an exercise price of $5.12 per
share in consideration for his service on the Board of Directors in lieu of
directors' compensation.
 
    Effective January 1, 1996, the Company granted to Mr. Sturgess, the
Company's former Chairman, President and Chief Executive Officer, in
consideration for services rendered in such capacity (i) options exercisable for
an aggregate of 240,000 shares of Common Stock at an exercise price of $12.50
per share (subject to quarterly increases until the occurrence of a Vesting
Event) and (ii) options exercisable for an aggregate of 120,000 shares of Common
Stock at a fixed exercise price of $5.12 per share. In November 1996, in
connection with the resignation of Mr. Sturgess as Chairman, President and Chief
Executive Officer of the Company, the Company and Mr. Sturgess entered into a
termination agreement whereby Mr. Sturgess retained options exercisable for an
aggregate of 240,000 shares of Common Stock, at an exercise price of $12.50 per
share (subject to quarterly increases until the occurrence of a Vesting Event)
with the terms of such options being amended such that options exercisable for
160,000 of such shares
 
                                       50
<PAGE>
would be exercisable upon the occurrence of a Vesting Event and options
exercisable for the remaining 80,000 of such shares would become exercisable
upon the occurrence of certain events by March 31, 1997. The contingent events
mentioned above did not occur within the prescribed period and, therefore, such
options to purchase 80,000 shares of Common Stock have terminated.
 
    The Company is currently in the process of amending the Company's Management
Equity Plan, subject to stockholder approval, to increase the number of options
available for issuance thereunder by approximately 1.5 million shares. On August
25, 1997, the Company filed a preliminary proxy statement with the Commission
relating to the solicitation of consents from the stockholders of the Company to
amend the Management Equity Plan. The Company expects that it will receive the
consent of the requisite number of shares of Common Stock required to approve
such amendment.
 
EMPLOYMENT AGREEMENTS
 
    The Company and Randall W. Larrimore entered into an employment agreement as
of May 23, 1997 to serve as President and Chief Executive Officer. Pursuant to
the agreement, Mr. Larrimore's employment begins on May 23, 1997 and continues
until Mr. Larrimore or the Company notifies the other party of a termination of
such employment. If Mr. Larrimore notifies the Company, the term of employment
is deemed to end 90 days after such notification, and if the Company notifies
Mr. Larrimore, the term of employment is deemed to end two years after such
notification. The term of employment may also be terminated earlier by either
Mr. Larrimore or the Company as described below. The agreement provides for an
annual base salary of at least $495,000, plus participation in all bonus, stock
option and other benefit plans generally available to executive officers of the
Company. The agreement also provides for a supplemental pension benefit that

    If Mr. Larrimore's employment is terminated by the Company (other than for
Cause, as defined in the agreement) without the specified notice, or by Mr.
Larrimore for Good Reason (as defined in the agreement), he will be entitled to
his salary and bonuses earned to the date of termination plus an amount equal to
two times his base pay plus bonuses, and his stock options will continue to be
or become exercisable during the 24 months following such termination. If his
employment terminates due to his death or disability, he will receive an amount
equal to his annual salary plus bonus, his unexercisable options will be
forfeited, and his exercisable options will remain exercisable for up to one
year following such termination. If there is a Change in Control (as defined in
the agreement), all stock options held by Mr. Larrimore will become exercisable.
If Mr. Larrimore's employment is terminated other than for Cause, Mr. Larrimore,
his spouse, and his eligible dependents may be allowed to participate in the
Company's health plan for a specified period, subject to certain limitations on
nonemployee participation and subject to Mr. Larrimore (or his spouse or
dependents) paying for such coverage.
 
    Effective as of June 1, 1997, the Company entered into new employment
agreements with Messrs. Bushell, Rowsey and Schwarz. Pursuant to such
agreements, the term of employment begins on June 1, 1997 and continues until
the executive or the Company notifies the other party. If the executive notifies
the Company, the term of employment ends 90 days after such notification, and if
the Company notifies the executive, the term of employment ends at the later of
(i) June 1, 2000 or (ii) two years after such notification. The term of
employment may also be terminated earlier by either the executive or the
Company. The agreements provide for an annual base salary of at least $265,000,
plus participation in all bonus, stock option and other benefit plans generally
available to executive officers of the Company.
 
    If the executive's employment is terminated due to death or disability, he
is entitled to an amount equal to the sum of his annual base salary and his
previous year's annual incentive compensation award payable over a 12-month
period. If the executive's employment is terminated by the Company without Cause
(as defined in the agreement) or by him for Good Reason (as defined in the
agreement), he is entitled to a severance amount (subject to mitigation) equal
to the sum of his base salary and bonuses for
 
                                       51
<PAGE>
the months remaining in the term of employment (or which would have been
remaining in the term of employment if the Company had given notice on the
termination date) payable over the severance period, and continued welfare
benefit coverage over such severance period. If the executive's employment is
terminated for any reason other than for Cause, the Company will allow the
executive, his spouse, and his eligible dependents to participate in the
Company's health plan for a specified period, subject to certain limitations on
nonemployee participation and subject to the executive (or his spouse or
dependents) paying for such coverage.
 
    In addition, the Company has also entered into employment agreements with
certain of its other executive officers. Such agreements typically have a one or
two year term.

issuable upon exercise of Lender Warrants or 758,994 shares of Common Stock
issuable upon conversion of the Nonvoting Common Stock) will be freely tradable
without restriction or further registration under the Securities Act. All of the
remaining 7,315,927 shares of Common Stock held by existing stockholders, 6,993
shares issuable upon the exercise of Preferred B Warrants, and 14,648 shares

Securities Act or are sold pursuant to an available exemption from registration,
including Rule 144 under the Securities Act.
 
    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least one
year (including the holding period of any prior owner except an "affiliate" (as
that term is defined in Rule 144)) is entitled to sell, within any three-month
period, a number of those shares that does not exceed the greater of (i) 1% of
the then outstanding shares of the Common Stock (144,568 shares immediately
after this Offering) or (ii) the average weekly trading volume in the Common
Stock during the four calendar weeks preceding the date on which notice of the
sale is filed with the Securities and Exchange Commission (the "Commission").
Sales under Rule 144 are also subject to certain manner of sale provisions,
notice requirements and requirements as to the availability of current public
information concerning the Company. Rule 144 provides that a person (or persons
whose shares are aggregated) who is not deemed to have been an affiliate of the
Company at any time during the 90 days preceding a sale, and who has
beneficially owned shares for at least two years (including the holding period
of any prior owner except an "affiliate") is entitled to sell those shares under
Rule 144(k) without regard to the limitations described above.
 
    After completion of the Offering and expiration of the 90-day lockup
agreement described below, 7,315,927 shares (7,064,010 shares if the
Underwriters' over-allotment options are exercised in full) of Common Stock held
by stockholders prior to the consummation of the Offering will be eligible for
sale on the open market under Rule 144 (as currently in effect), subject to the
volume and manner of sales limitations referred to above.
 
    Certain stockholders and holders of Warrants have been granted certain
rights with respect to registration under the Securities Act of shares of Common
Stock held by them. Pursuant to the Lender Registration Rights Agreement, the
Company has effected a shelf registration with respect to all 1,151,177 shares
of Common Stock issuable upon exercise of the Lender Warrants and Nonvoting
Common Stock that will remain outstanding after completion of the Offering. See
"Certain Transactions--Warrants." The Company also intends to register under the
Securities Act the shares of Common Stock issuable upon exercise of certain
Merger Incentive Options.
 
    The Company's directors and executive officers, the Selling Stockholders and
certain other significant stockholders of the Company have agreed that, for the
period of up to 90 days following the date of this Prospectus, each will not (i)
directly or indirectly, offer to sell, contract to sell or otherwise sell,
dispose of, loan, pledge or grant any rights with respect to (collectively, a
"Disposition"), any shares of Common Stock, any options or warrants to purchase
any shares of Common Stock or any securities convertible into or exchangeable
for shares of Common Stock (collectively, the "Securities"), now owned or
hereafter acquired by the undersigned or with respect to which the undersigned
has or hereafter acquires the power of disposition, otherwise than (a) the
shares offered hereby by such persons, (b) as a bona fide gift or gifts,
provided the donee or donees thereof agree to be bound in writing by the terms
of the "lock-up"

agreement, (c) as a distribution to limited partners or stockholders of the
undersigned, provided that the distributees thereof agree in writing to be bound
by the terms of the "lock-up" agreement, or (d) with prior written consent of
the Representatives or (ii) make any demand for or exercise any right with
respect to the registration of any Securities. In addition, the Company has
agreed that, during the period of up to 90 days from the date of this
Prospectus, it will not, without the prior written consent of the
Representatives, either directly or indirectly, effect a Disposition with
respect to any Securities, other than the shares offered hereby and the
Company's issuance of Common Stock upon exercise of Employee Stock Options.
 
    The Company can make no prediction as to the effect, if any, that sales of
shares or the availability of shares for sale will have on the market price for
the Common Stock prevailing from time to time. Nevertheless, sales of
substantial amounts of Common Stock in the public market could adversely affect
prevailing market prices. See "Risk Factors--Impact of Shares Eligible for
Future Sale."

$0.01 par value ("preferred stock"), (ii) 40,000,000 shares of Common Stock, and
(iii) 5,000,000 shares of a class designated as nonvoting common stock, $0.01
par value (the "Nonvoting Common Stock"). Of the authorized shares of capital
stock, 11,619,755 shares of Common Stock and 758,994 shares of Nonvoting Common
Stock were outstanding as of September 3, 1997. No shares of preferred stock
were outstanding as of September 3, 1997. Employee Stock Options exercisable for
an aggregate of 2,631,768 shares of Common Stock and Warrants exercisable for an
aggregate of 1,236,175 shares of Common Stock were outstanding as of such date.
 
COMMON STOCK AND NONVOTING COMMON STOCK
 
    Holders of shares of Common Stock and Nonvoting Common Stock are entitled to
share ratably in such dividends as may be declared by the Board of Directors and
paid by the Company out of funds legally available therefor, subject to prior
rights of outstanding shares of any preferred stock and certain restrictions
under agreements governing the Company's indebtedness. See "Common Stock Price
Range and Dividend Policy" and "Description of Indebtedness." In the event of
any dissolution, liquidation or winding up of the Company, holders of shares of
Common Stock and Nonvoting Common Stock are entitled to share ratably in assets
remaining after payment of all liabilities and liquidation preferences, if any.
 
    Except as otherwise required by law, the holders of Common Stock are
entitled to one vote per share on all matters voted on by stockholders,
including the election of directors. The holders of a majority of shares of
Common Stock represented at a meeting of stockholders can elect all of the
directors to be elected at such a meeting.
 
    Holders of shares of Common Stock have no preemptive, cumulative voting,
subscription, redemption or conversion rights. The currently outstanding shares
of Common Stock are fully paid and nonassessable, and the shares of Common Stock
to be outstanding upon completion of the Offering will be fully paid and
nonassessable. The rights, preferences and privileges of holders of Common Stock
are subject to the rights of any series of preferred stock which the Company may
issue in the future. Shares of Nonvoting Common Stock are entitled to all rights
granted to, and subject to all restrictions imposed on, shares of Common Stock,
other than the right to vote, except in certain limited circumstances. Subject
to certain restrictions, shares of Nonvoting Common Stock are convertible at any
time at the option of the holder thereof into shares of Common Stock for no
additional consideration.
 
PREFERRED STOCK
 
    On July 28, 1995, the Company consummated the repurchase of all of its
outstanding Series B Preferred Stock, $0.01 par value, together with accrued and
unpaid dividends thereon, for an aggregate
 
                                       57
<PAGE>
purchase price of $7.0 million. On September 2, 1997, the Company completed the
redemption of all outstanding shares of Preferred Stock for an aggregate
redemption price of $21.3 million (the "Redemption Price"). The Redemption Price
was paid from borrowings under the Revolving Credit Facilities. As a result of
the redemption of the Preferred Stock, the Company does not have any preferred
stock outstanding as of the date hereof.
 
    The Company is authorized to issue 1,500,000 shares of preferred stock. The
Board of Directors of the Company, in its sole discretion, may designate and
issue one or more series of preferred stock from the authorized and unissued
shares of preferred stock. Subject to limitations imposed by law or the
Company's Charter, the Board of Directors is empowered to determine the
designation of and the number of shares constituting a series of preferred
stock, the dividend rate thereon, the terms and conditions of any voting and
conversion rights for the series, the amounts payable on the series upon
redemption or upon the liquidation, dissolution or winding-up of the Company,
the provisions of any sinking fund for the redemption or purchase of shares of
any series, and the preferences and relative rights among the series of
preferred stock. Such rights, preferences, privileges and limitations could
adversely affect the rights of holders of Common Stock. In addition, the Board
of Directors of the Company, subject to its fiduciary duties, may issue shares
of preferred stock in order to deter a takeover attempt. See "Risk Factors--
Possible Anti-Takeover Effects."
 
LENDER WARRANTS
 
    The Company expects that Lender Warrants exercisable for an aggregate of
392,183 shares of Common Stock will remain outstanding after the Offering. The
Lender Warrants were originally issued pursuant to a Warrant Agreement (the
"Lender Warrant Agreement") in connection with the Associated Transaction and
contain customary anti-dilution provisions and are exercisable through January
31, 2002. In addition, the Company is entitled to repurchase the Lender Warrants
at any time after January 31, 1999 at the greater of the then Fair Market Value
(as defined in the Lender Warrant Agreement) of the shares of Common Stock (less
the applicable exercise price for the Lender Warrants) or the Equity Value
(which is defined generally as (i) five times the Company's and its consolidated
subsidiaries' earnings before interest, taxes, depreciation and amortization,
minus (ii) non-convertible debt of the Company and its consolidated
subsidiaries, minus (iii) preferred stock of the Company, plus (iv) cash and
cash equivalents). In the event the Company repurchases Lender Warrants or
shares of Common Stock pursuant to the call option granted under the Lender
Warrant Agreement and, within 12 months after the date of such repurchase, the
Company, any subsidiary of the Company, or Wingate Partners, Cumberland or Good
Capital or their subsidiaries, or affiliates (but excluding any limited partners
of Wingate Partners as such) or associates has entered into any contract
relating to a merger of the Company or sale of all or substantially all of the
assets of the Company or any subsidiary of the Company (a "Look Back Event"),
then the Company is required to make a payment to each holder whose Lender
Warrants or shares of Common Stock were repurchased in an amount generally equal
to (i) the excess of the fair market value of the consideration received by the
Company, the subsidiaries and the stockholders of the Company (on a per share
basis) in connection with the Look Back Event over (ii) the sum of (a) the
amount paid to such holder pursuant to the exercise by the Company of its call
option plus (b) imputed interest on such amount through the date of repurchase
at the base rate under the Company's existing Credit Agreement.
 
    The Lender Warrant Agreement also contains certain put rights which
currently require the Company to repurchase such Lender Warrants upon demand by
the holder thereof. The purchase price payable by the Company or USSC upon the
exercise of the put rights is generally equal to the greater of the then Fair
Market Value (as defined in the Lender Warrant Agreement) of the shares of
Common Stock (less the applicable exercise price of the Lender Warrants) or the
Equity Value. The Lender Warrants may be put to the Company at any time prior to
consummation of the Offering, at which time such put rights will terminate.
 
                                       58
<PAGE>
    The Lender Warrant Agreement provides the holders with certain "tag along
rights" which entitle such holders to participate, on a pro rata basis, in
certain sales of shares of Common Stock by Wingate Partners, Cumberland, Good
Capital or any of their subsidiaries, affiliates (but excluding any limited
partners of Wingate Partners as such) or associates. Pursuant to the Lender
Warrant Agreement, Wingate Partners has been granted certain "go along rights"
which are triggered (subject to certain exceptions) in the event (i) Wingate
Partners sells 100% of its equity interest in the Company in a private offering,
(ii) all or substantially all of the assets of the Company are sold and the
proceeds of such sale are distributed to the stockholders of the Company or
(iii) the Company participates in a merger or consolidation. In the event
Wingate Partners exercises its "go along rights" in connection with the
occurrence of one of the events described above, each holder of Lender Warrants
would become obligated to sell all Lender Warrants and shares of Warrant Stock
(as defined in the Lender Warrant Agreement) held by such holders in the
applicable transaction and to vote all shares of Common Stock in favor of such
transaction.
 
    The Lender Warrant Agreement contains a mechanism whereby after the Lender
Warrants (or a portion thereof) have been sold pursuant to the put rights, tag
along rights or go along rights under the Lender Warrants (provided that such
events have occurred prior to January 31, 1999), each holder of Tranche B Lender
Warrants (the "Tranche B Warrants") is required to refund to the Company a
portion of the aggregate amount earned by such holder on its Tranche B Warrant
investment (the "Refunded Amount"). The Refunded Amount is only required to be
paid in the event the amount earned by all holders of the Tranche B Warrants
exceeds $6,500,000 and such holders received an internal rate of return on their
investment represented by the Tranche B portion of the Associated term loans in
effect prior to the Merger of at least 25%. The Refunded Amount ranges from 10%
of amounts earned on the Tranche B Warrants to 40% of such amounts, depending
upon the amount by which the aggregate amount earned by all holders of the
Tranche B Warrants exceeds $6,500,000 and the internal rate of return received
by such holders on their investment represented by the Tranche B portion of the
Associated term loans in effect prior to the Merger exceeds 25%. In July 1997,
the Company and holders of Lender Warrants amended the Lender Warrant Agreement
to eliminate the requirement of holders to pay the Refunded Amount in exchange
for a waiver of certain dilution adjustments in connection with the grant of
certain Employee Stock Options.
 
    Pursuant to the terms of the Lender Warrant Agreement, if at any time the
Company does not have securities registered under Section 12(b) or 12(g) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and is not
required to file reports under Section 15(d) of the Exchange Act, the holders of
the Lender Warrants will be entitled to preemptive rights with respect to
certain issuances of shares of Common Stock by the Company and to board
observation rights for meetings of the Boards of Directors of the Company and
its subsidiaries. The Lender Warrants also contain certain covenants and
agreements with respect to, among other things, (i) transactions with affiliates
(other than the payment of a limited amount of management fees to Wingate
Partners, Cumberland and Good Capital), (ii) certain mergers, reorganizations,
recapitalization and other events with respect to the shares of Common Stock,
(iii) the redemption of shares of Common Stock, (iv) changes of the fiscal year
of the Company, (v) the taking of actions that would cause the Company or any
subsidiary of the Company to own less than 80% of any subsidiary of the Company,
except that the Company and each subsidiary of the Company may own a percentage
of the stock of any such subsidiary not lower than the percentage owned at the
effective time of the Merger, (vi) delivery of financial statements of the
Company and (vii) indemnification.
 
PREFERRED B WARRANTS
 
    The Company expects that Preferred B Warrants exercisable for an aggregate
of 6,993 shares of Common Stock will remain outstanding after the Offering. The
Preferred B Warrants contain customary antidilution provisions and are
exercisable through January 31, 2002. The Preferred B Warrants provide the
holders thereof with certain "tag along rights" which entitle such holders to
participate, on a pro rata basis, in certain sales of shares of Common Stock by
Wingate Partners, Cumberland, Good Capital or
 
                                       59
<PAGE>
certain of their affiliates. Pursuant to the Preferred B Warrants, Wingate
Partners has been granted certain "go along rights" which are triggered (subject
to certain exceptions) in the event (i) Wingate Partners sells 100% of its
equity interest in the Company in a private offering, (ii) all or substantially
all of the assets of the Company are sold and the proceeds of such sale are
distributed to the stockholders of the Company or (iii) the Company participates
in a merger or consolidation. In the event Wingate Partners exercises its "go
along rights" in connection with the occurrence of one of the events described
above, each holder of Preferred B Warrants would become obligated to sell all
Preferred B Warrants and shares of Common Stock held by such holders in the
applicable transaction and to vote all shares of Common Stock in favor of such
transaction.
 
    Pursuant to the terms of the Preferred B Warrants, if at any time the
Company does not have securities registered under Section 12(b) or 12(g) of the
Exchange Act and is not required to file reports under Section 15(d) of the
Exchange Act, the holders of the Preferred B Warrants will be entitled to
preemptive rights with respect to certain issuances of shares of Common Stock by
the Company and to board observation rights for meetings of the Boards of
Directors of the Company and its subsidiaries. The Preferred B Warrants also
contain certain covenants and agreements with respect to, among other things,
(i) transactions with affiliates (other than certain specified transactions with
Wingate Partners, Cumberland and Good Capital), (ii) certain mergers,
reorganizations, recapitalizations and other events with respect to the shares
of Common Stock, (iii) the repurchase or redemption of shares of Common Stock,
(iv) changes of the fiscal year of the Company, (v) the taking of actions that
would cause the Company or any subsidiary of the Company to own less than 80% of
any subsidiary of the Company, except that the Company and each subsidiary of
the Company may own a percentage of the stock of any such subsidiary not lower
than the percentage owned at the effective time of the Merger, (vi) delivery of
financial statements of the Company, and (vii) indemnification.
 
SPECIAL PROVISIONS OF THE CHARTER AND BYLAWS
 
    The Charter and Bylaws provide include certain provisions that could have
anti-takeover effects. The provisions are intended to enhance the likelihood of
continuity and stability in the composition of, and in the policies formulated
by, the Board of Directors. These provisions are also intended to help ensure
that the Board of Directors, if confronted by an unsolicited proposal from a
third party that has acquired a block of stock of the Company, will have
sufficient time to review the proposal, to develop appropriate alternatives to
the proposal, and to act in what the Board of Directors believes to be the best
interests of the Company and its stockholders. The provisions of the Charter
described under "Classified Board of Directors" and "Vote Required for Certain
Business Combinations" below may not be amended or repealed unless approved by
holders of at least 80% of the voting power of the then outstanding Common
Stock. The following is a summary of the provisions of the Charter and Bylaws
and is qualified in its entirety by reference to such documents in their
respective forms filed as exhibits to the Registration Statement of which this
Prospectus forms a part.
 
    CLASSIFIED BOARD OF DIRECTORS.  The Charter provides for three classes of
directors, which serve staggered three-year terms and which shall be elected by
the holders of the Common Stock. Under certain circumstances, the classification
of directors has the effect of making it more difficult for stockholders to
change the composition of the Board of Directors in a relatively short period of
time. Given the current structure of the Company's Board of Directors, at least
two annual meetings of stockholders, instead of one, will generally be required
to effect a change in a majority of the Board of Directors at any time when the
Company has seven or more directors.
 
    VOTE REQUIRED FOR CERTAIN BUSINESS COMBINATIONS.  The Company is subject to
Section 203 of the Delaware General Corporation Law, as amended (the "DGCL"),
which prohibits a publicly held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an interested
stockholder, unless one of the following events occurs: (i) prior to the date of
the business combination, the transaction is
 
                                       60
<PAGE>
approved by the board of directors of the corporation; (ii) upon consummation of
the transaction which resulted in the stockholder becoming an interested
stockholder, the interested stockholder owns at least 85% of the outstanding
voting stock; or (iii) on or after such date the business combination is
approved by the board and by the affirmative vote of at least 66 2/3% of the
outstanding voting stock which is not owned by the interested stockholder. A
"business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the stockholder. An "interested stockholder"
for purposes of the DGCL is a person who, together with affiliates and
associates, owns (or within three years, did own) 15% or more of the
corporation's voting stock.
 
    In addition, the Charter provides that certain transactions involving an
"interested stockholder" require the affirmative vote of the holders of at least
80% of the voting power of the then outstanding Common Stock. Such transactions
include certain (i) mergers or consolidations of the Company, (ii) sales,
leases, pledges and similar transactions involving the Company's assets, (iii)
issuances or transfers of the Company's securities, (iv) adoptions of a plan of
liquidation or dissolution of the Company and (v) reclassifications and
recapitalizations of the Company. Such vote requirement is in addition to that
required by the DGCL as described in the preceding paragraph. An "interested
stockholder" for purposes of the Charter is a person who beneficially owns 20%
or more of the Company's voting stock or an affiliate of the Company who at any
time within the previous two years beneficially owned 20% or more of the
Company's voting stock. Wingate constitutes an "interested stockholder" for
purposes of both the DGCL and the Charter.
 
    LIMITATIONS ON DIRECTORS' LIABILITY.  The Charter provides that, to the
fullest extent permitted by Delaware law, no director shall be liable to the
Company or its stockholders for monetary damages for breach of fiduciary duty as
a director. By virtue of these provisions, a director of the Company is not
personally liable for monetary damages for a breach of such director's fiduciary
duty except for liability for (i) breach of the duty of loyalty to the Company
or to its stockholder, (ii) acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) dividends or stock
repurchases or redemptions that are unlawful under the DGCL, and (iv) any
transaction from which such director receives an improper personal benefit. In
addition, the Charter provides that if the DGCL is amended to authorize the
further elimination or limitation of the liability of a director, then the
liability of the directors will be eliminated or limited to the fullest extent
permitted by the DGCL.
 
                          DESCRIPTION OF INDEBTEDNESS
 
CREDIT FACILITIES
 
    The Company is currently a party to the Credit Agreement with Chase Bank, as
agent, and a group of banks and financial institutions (including Chase Bank,
the "Senior Lenders"). The following is a summary of the principal terms of the
Credit Agreement, which summary does not purport to be complete and is subject
to, and is qualified in its entirety by reference to, all the provisions of the
Credit Agreement as further amended from time to time, a copy of which is
available upon request to the Company. See "Available Information."
 
    As of the date hereof, the credit facilities under the Credit Agreement
consisted of $174.7 million of borrowings under the Term Loan Facilities and up
to $325.0 million of revolving loan borrowings under the Revolving Credit
Facility. This agreement was amended on October 31, 1996 to provide funding for
the acquisition of Lagasse to extend the maturities, to adjust the pricing and
to revise certain covenants. A portion of the Term Loan Facilities will be
repaid out of the proceeds of this Offering. See "Use of Proceeds."
 
    The loans outstanding under the Term Loan Facilities and the Revolving
Credit Facility generally bear interest as determined within a set range with
the rate based on the ratio of total debt to earnings before interest, taxes,
depreciation and amortization (EBITDA). The Tranche A Facility and the Revolving
Credit Facility bear interest at prime plus 0.25% to 1.25% or, at the Company's
option, LIBOR plus 1.50% to
 
                                       61
<PAGE>
2.50%. The Tranche B Facility bears interest at prime plus 1.25% to 1.75% or, at
the Company's option, LIBOR plus 2.50% to 3.00%.
 
    The current outstanding principal balance of Term Loan Facilities consist of
a $117.8 million Tranche A Term Loan Facility and a $56.9 million Tranche B term
loan Facility. Quarterly payments under the Tranche A facility range from $4.98
million at June 30, 1997 to $8.30 million at September 30, 2001. Quarterly
payments under the Tranche B Facility range from $0.22 million at June 30, 1977
to $6.64 million at September 30, 2003. On March 31, 1997, principal payments of
$15.9 million and $7.4 million were required to be paid from Excess Cash Flow
(as defined in the Credit Agreement) at December 31, 1996 for the Tranche A and
Tranche B Facilities, respectively.
 
    The Revolving Credit Facility is limited to the lesser of $325.0 million or
a borrowing base equal to: 80% of Eligible Receivables (as defined in the Credit
Agreement); plus 50% of Eligible Inventory (as defined in the Credit Agreement)
(provided that no more than 60% or, during certain periods 65%, of the Borrowing
Base may be attributable to Eligible Inventory); plus the aggregate amount of
cover for Letter of Credit Liabilities (as defined in the Credit Agreement). In
addition, for each fiscal year, the Company must repay revolving loans so that
for a period of 30 consecutive days in each fiscal year the aggregate revolving
loans do not exceed $250.0 million. The Revolving Credit Facility matures on
October 31, 2001.
 
    Loans under the Term Loan Facilities and the Revolving Credit Facility may
be prepaid at any time and are subject to certain mandatory prepayments out of
(i) net proceeds received from the issuance of equity by USSC or any of its
subsidiaries subject to certain exceptions provided within the Credit Agreement,
(ii) net proceeds from certain asset sales in excess of $15.0 million and (iii)
50% of USSC's Excess Cash Flow (as defined in the Credit Agreement) if the Debt
to Cash Flow Ratio (as defined in the Credit Agreement) as of the last day of
the fiscal year is less than 3 to 1 and, otherwise, 75% of USSC's Excess Cash
Flow. Optional prepayments under the Term Loan Facilities will be applied, pro
rata to loans outstanding under the Tranche A Facility and the Tranche B
Facility (pro rata to the remaining installments). Mandatory prepayments will be
applied first, pro rata to loans outstanding under the Tranche A Facility and
the Tranche B Facility (pro rata to the remaining installments), and second, to
the permanent reduction of commitments (and the payment of loans outstanding)
under, the Revolving Credit Facility.
 
    The Term Loan Facilities and the Revolving Credit Facility are guaranteed,
on a joint and several basis, by the Company, and by all of the direct and
indirect domestic subsidiaries of USSC.
 
    The Term Loan Facilities and the Revolving Credit Facility are secured by
perfected first priority pledges of the stock of USSC, all of the stock of the
domestic direct and indirect subsidiaries of USSC and certain of the stock of
all of the foreign direct and indirect subsidiaries of USSC and security
interests in, and liens upon, all accounts receivable, inventory, contract
rights and other personal and certain real property of USSC and its domestic
subsidiaries. The Company has negotiated the release of the lien on accounts
receivable in the event the Company enters into an asset-backed securitization.
The Company is currently pursuing such an asset-backed securitization, although
no definitive agreement has been reached as of the date of this Prospectus.
 
    The Credit Agreement contains representations and warranties, affirmative
and negative covenants and events of default customary for financings of its
type.
 
    The right of the Company to participate in any distribution of earnings or
assets of USSC is subject to the prior claims of the creditors of USSC. In
addition, the Credit Agreement contains certain restrictive covenants, including
covenants that restrict or prohibit USSC's ability to pay dividends and make
other distributions to the Company.
 
NOTES
 
    The Notes were issued on May 3, 1995 pursuant to the Indenture. As of the
date hereof, the aggregate outstanding principal amount of Notes was $150.0
million. The Notes are unsecured senior subordinated
 
                                       62
<PAGE>
obligations of USSC, and payment of the Notes is fully and unconditionally
guaranteed by the Company on a senior subordinated basis. The Notes mature on
May 1, 2005, and bear interest at the rate of 12 3/4% per annum, payable
semiannually on May 1 and November 1 of each year.
 
    The Indenture provides that, prior to May 1, 1998, USSC may redeem, at its
option (the "Equity Clawback Option"), up to $50.0 million aggregate principal
amount of Notes with the proceeds of one or more Public Equity Offerings (as
defined) at 112.75% of the principal amount thereof, together with accrued and
unpaid interest, if any, to the date of redemption; provided (i) that the Equity
Clawback Option must be exercised within 180 days following the Public Equity
Offering, and (ii) that Notes having an aggregate principal amount of $100.0
million remain outstanding immediately after any such redemption. The Company
intends to contribute a portion of the proceeds from this Offering to USSC, so
that USSC may redeem $50.0 million aggregate principal amount of Notes and pay
the redemption premium thereon of approximately $6.4 million in accordance with
this provision. Such redemption shall be made on a pro rata basis. See "Use of
Proceeds."
 
    In addition, the Notes are redeemable at the option of USSC at any time on
or after May 1, 2000, in whole or in part, at the following redemption prices
(expressed as percentages of principal amount):
 
<TABLE>

</TABLE>
 
and thereafter at 100.0% of the principal amount, in each case together with
accrued and unpaid interest, if any, to the redemption date.
 
    Upon the occurrence of a change of control (which term includes the
acquisition by any person or group of more than 50% of the voting power of the
outstanding common stock of either United or USSC or certain significant changes
in the composition of the Board of Directors of either United or USSC), USSC
shall be obligated to offer to redeem all or a portion of each holder's Notes at
101% of the principal amount thereof, together with accrued and unpaid interest,
if any, to the date of such redemption. Such obligation, if it arose, could have
a material adverse effect on the Company. Furthermore, such provision could
delay, deter or prevent a takeover attempt.
 
    The Indenture governing the Notes contains certain covenants, including
limitations on the incurrence of indebtedness, the making of restricted
payments, transactions with affiliates, the existence of liens, disposition of
proceeds of asset sales, the making of guarantees by restricted subsidiaries,
transfer and issuances of stock of subsidiaries, the imposition of certain
payment restrictions on restricted subsidiaries and certain mergers and sales of
assets. Such covenants may interfere with USSC's ability to pay dividends to the
Company. See "Risk Factors--Restrictions Imposed by Terms of Indebtedness."

    The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that, if any of the foregoing
shares of Common Stock are purchased by the Underwriters pursuant to the
Underwriting Agreement, all such shares must be so purchased. The Company and,
to a limited extent, the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
    The Company and the Selling Stockholders have been advised that the
Underwriters propose initially to offer the shares of Common Stock to the public
at the public offering price set forth on the cover page of this Prospectus and
to certain selected dealers (who may include the Underwriters) at such public
offering price less a concession not to exceed $     per share. The selected
dealers may reallow a concession to certain other dealers not to exceed $
per share. After the Offering to the public, the public offering price, the
concession to selected dealers and the reallowance to other dealers may be
changed by the Underwriters.
 
    In order to facilitate this Offering, certain persons participating in this
Offering may engage in transactions that stabilize, maintain or otherwise affect
the price of the Common Stock during and after this Offering. Specifically, the
Underwriters may over-allot or otherwise create a short position in the Common
Stock for their own account by selling more shares of Common Stock than have
been sold to them by the Company and the Selling Stockholders. The Underwriters
may elect to cover any such short position by purchasing shares of Common Stock
in the open market or by exercising the over-allotment option granted to the
Underwriters. In addition, such persons may stabilize or maintain the price of
the Common Stock by bidding for or purchasing shares of Common Stock in the open
market and may impose penalty bids, under which selling concessions allowed to
syndicate members or other broker-dealers participating in this Offering are
reclaimed if shares of Common Stock previously distributed in this Offering are
repurchased in connection with stabilization transactions or otherwise. The
effect of these transactions may be to stabilize or maintain the market price of
the Common Stock at a level above that which might otherwise prevail in the open
market. The imposition of a penalty bid may also affect the price of the Common
Stock to the extent that it discourages resales thereof. No representation is
made as to the magnitude or effect of any such stabilization or other
transactions. Such transactions may be effected on the Nasdaq National Market or
otherwise and, if commenced, may be discontinued at any time.
 
                                       64
<PAGE>
    Certain persons participating in this Offering may also engage in passive
market making transactions in the Common Stock on the Nasdaq National Market in
accordance with Rule 103 of Regulation M under the Exchange Act. Rule 103
permits, upon the satisfaction of certain conditions, underwriting and selling
group members participating in a distribution that are also registered Nasdaq
market makers in the security being distributed (or a related security) to
engage in limited passive market making transactions during the period when
Regulation M would otherwise prohibit such activity. In general, a passive
market maker may not bid for or purchase a security at a price that exceeds the
highest independent bid for those securities by a person that is not
participating in the distribution and must identify its passive market making
bids on Nasdaq electronic inter-dealer reporting system. In addition, the net
daily purchases made by a passive market maker generally may not exceed 30% of
such market maker's average daily trading volume in the security for the two
full consecutive calendar months (or any 60 consecutive days ending within 10
days) immediately preceding the date of filing of the Registration Statement of
which this Prospectus forms a part.
 
    Of the shares being sold by the Selling Stockholders, 837,000 shares
(1,115,568 shares if the Underwriters' over-allotment option is exercised in
full) are issuable pursuant to currently exercisable and fully transferable
Warrants. Concurrent with the closing of this Offering, certain Selling
Stockholders will sell such Warrants to the Underwriters in consideration of the
payment of a per share amount equal to the difference between the Proceeds to
Selling Stockholders set forth on the cover page of this Prospectus and the
Warrant exercise price. The Underwriters will then exercise the Warrants by
paying the Company the exercise price ranging from $0.10 to $0.15 per Warrant
and sell the shares issuable upon exercise of the Warrants to the public at the
Price to Public set forth on the cover page of this Prospectus.
 
    The Selling Stockholders have granted the Underwriters an option to purchase
up to 600,000 additional shares of Common Stock at the public offering price
less the underwriting discounts and commissions set forth on the cover page of
this Prospectus, solely to cover over-allotments, if any. Such option may be
exercised at any time until 30 days after the date of this Prospectus. If the
Underwriters exercise such option, each of the Underwriters will be committed,
subject to certain conditions, to purchase a number of additional shares
proportionate to such Underwriter's initial commitment as indicated in the
preceding table.
 
    Each of the Company, its directors and executive officers, the Selling
Stockholders and certain other significant stockholders of the Company has
agreed that for a period of 90 days from the date of this Prospectus, it will
not, without the prior written consent of Bear, Stearns & Co. Inc., issue, sell,
offer or agree to sell, grant any option for the sale, or otherwise dispose of,
directly or indirectly, any Common Stock or any securities substantially similar
to the Common Stock or any securities convertible into, exercisable for or
exchangeable for Common Stock or securities substantially similar to the Common
Stock, otherwise than in this Offering or upon the exercise of presently
outstanding stock options.
 
    Chase Securities is an affiliate of Chase Bank which is the agent and a
lender under the Credit Agreement. A portion of the proceeds of this Offering
will be used to repay certain indebtedness outstanding under the Credit
Agreement. See "Use of Proceeds" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources."
Chase Securities is also an affiliate of CMIH which is a material stockholder of
the Company and one of the Selling Stockholders in this Offering. As a result of
the repayment of certain indebtedness with the proceeds of the Offering and the
sale by CMIH of shares of Common Stock in the Offering, affiliates of Chase
Securities will receive more than 10% of the net proceeds of the Offering.
Accordingly, this Offering is being conducted in compliance with Rule 2710(c)(8)
of the Conduct Rules of the National Association of Securities Dealers, Inc.
("NASD") and the public offering price of the Common Stock can be no higher than
that recommended by a "qualified independent underwriter" meeting certain
standards. Bear, Stearns & Co. Inc. has agreed to serve in such capacity and
will recommend a price in compliance with the requirements of such rule. Bear,
Stearns & Co. Inc. has performed due diligence investigations and participated
in the preparation of this Prospectus and the Registration Statement of which
this Prospectus
 
                                       65
<PAGE>
forms a part. In accordance with the provisions of NASD rules, the Underwriters
will not confirm sales to any account over which they exercise discretionary
authority without the specific prior written approval of the customer. Chase
Securities and its affiliates have provided investment banking and general
financing and banking services to the Company and its predecessors for which
Chase Securities and its affiliates have received customary compensation. Chase
Securities and its affiliates may provide similar or other services in the
future to the Company. See "Certain Transactions--Certain Interests of Chase"
and "Principal and Selling Stockholders."
 
                                 LEGAL MATTERS
 
    Certain legal matters with respect to the Common Stock have been passed upon

                                    EXPERTS
 
    The consolidated financial statements and related schedule of the Company as
of and for each of the years ended December 31, 1995 and 1996 and the
consolidated financial statements and schedule of United for the seven months
ended March 30, 1995 appearing in the Company's Annual Report (Form 10-K) for
the year ended December 31, 1996 have been audited by Ernst & Young LLP,
independent auditors, as set forth in their reports thereon included therein and
incorporated herein by reference. Such consolidated financial statements and
related schedules and reports of independent auditors thereon have also been
included herein. Such consolidated financial statements and related schedules
are included herein and incorporated herein by reference in reliance upon such
reports given upon the authority of such firm as experts in accounting and
auditing.
 
    With respect to the unaudited condensed consolidated interim financial
information for the three months ended March 31, 1996 and 1997 and June 30, 1996
and 1997 and for the six months ended June 30, 1996 and 1997, incorporated by
reference in this Prospectus, Ernst & Young LLP have reported that they have
applied limited procedures in accordance with professional standards for a
review of such information. However, their separate reports, included in the
Company's Quarterly Reports on Form 10-Q for the quarters ended March 31, 1997
and June 30, 1997, and incorporated herein by reference, state that they did not
audit and they do not express an opinion on that interim financial information.
Accordingly, the degree of reliance on their reports on such information should
be restricted considering the limited nature of the review procedures applied.
The independent auditors are not subject to the liability provisions of Section
11 of the Securities Act for their reports on the unaudited interim financial
information because these reports are not a "report" or a "part" of the
Registration Statement prepared or certified by the auditors within the meaning
of Sections 7 and 11 of the Securities Act.
 
    The consolidated financial statements of Associated for the year ended
December 31, 1994 included in this Prospectus and the consolidated financial
statements of United for the year ended August 31, 1994 included in this
Prospectus have been audited by Arthur Andersen LLP, as indicated in its reports
with respect thereto, and are included herein in reliance upon the authority of
such firm as experts in accounting and auditing.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Stockholders and Board of
Directors of United Stationers Inc.
 
    We have audited the accompanying consolidated balance sheets of United
Stationers Inc. and Subsidiaries as of December 31, 1995 and 1996, and the
related consolidated statements of income, changes in stockholders' equity and
cash flows for each of the years then ended. 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 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, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of United
Stationers Inc. and Subsidiaries at December 31, 1995 and 1996, and the
consolidated results of their operations and their cash flows for each of the
years then ended in conformity with generally accepted accounting principles.
 
    As discussed in Note 3 to the consolidated financial statements, in 1995,
the Company changed its method of valuing inventory from the first-in, first-out
(FIFO) method to the last-in, first-out (LIFO) method.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION AND PURCHASE ACCOUNTING
 
    On March 30, 1995, Associated Holdings, Inc. ("Associated") purchased 92.5%
of the then outstanding shares of the common stock, $0.10 par value ("Common
Stock") of United Stationers Inc. ("United") for approximately $266.6 million in
the aggregate pursuant to a tender offer (the "Offer"). Immediately thereafter,
Associated merged with and into United (the "Merger" and, collectively with the
Offer, the "Acquisition"), and Associated Stationers, Inc. ("ASI"), a wholly
owned subsidiary of Associated merged with and into United Stationers Supply Co.
("USSC"), a wholly owned subsidiary of United, with United and USSC continuing
as the respective surviving corporations. United, as the surviving corporation
following the Merger, is referred to herein as the "Company." As a result of
share conversions in the Merger, immediately after the Merger, (i) the former
holders of common stock and common stock equivalents of Associated owned shares
of Common Stock and warrants or options to purchase shares of Common Stock
constituting in the aggregate approximately 80% of the shares of Common Stock on
a fully diluted basis, and (ii) holders of pre-Merger United common stock owned
in the aggregate approximately 20% of the shares of Common Stock on a fully
diluted basis. Although United was the surviving corporation in the Merger, the
transaction was treated as a reverse acquisition for accounting purposes with
Associated as the acquiring corporation.
 
    The financial information for the year ended December 31, 1995 includes
Associated only for the three months ended March 30, 1995 and the results of the
Company for the nine months ended December 31, 1995. Financial information prior
to 1995 reflects that of Associated only. All common and common equivalent
shares have been adjusted to reflect the 100% stock dividend effective November
9, 1995.
 
    The Acquisition has been accounted for using the purchase method of
accounting and, accordingly, the purchase price has been allocated to the assets
purchased and the liabilities assumed based upon the estimated fair values at
the date of acquisition with the excess of cost over fair value allocated to
goodwill. The purchase price allocation to property, plant and equipment is
amortized over the estimated useful lives ranging from 3 to 40 years. Goodwill
is amortized over 40 years.
 
    The total purchase price of United by Associated and its allocation to
assets and liabilities acquired are as follows (dollars in thousands):

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. BASIS OF PRESENTATION AND PURCHASE ACCOUNTING (CONTINUED)
    Immediately following the Merger, the number of outstanding shares of Common
Stock was 11,996,154 (or 13,947,440 on a fully diluted basis), of which (i) the
former holders of Class A Common Stock, $0.01 par value, and Class B Common
Stock, $0.01 par value, of Associated (collectively "Associated Common Stock")
and warrants or options to purchase Associated Common Stock in the aggregate
owned 9,206,666 shares constituting approximately 76.7% of the outstanding
shares of Common Stock and outstanding warrants or options for 1,951,286 shares
(collectively 80.0% on a fully diluted basis) and (ii) pre-Merger holders of
shares of Common Stock (other than Associated-owned and treasury shares) in the
aggregate owned 2,789,488 shares of Common Stock constituting approximately
23.3% of the outstanding shares (or 20.0% on a fully diluted basis). As used in
this paragraph, the term " Common Stock " includes shares of Nonvoting Common
Stock, $0.01 par value, of the Company, which are immediately convertible into
Voting Common Stock.
 
    On October 31, 1996, the Company acquired all of the capital stock of
Lagasse Bros., Inc. ("Lagasse") for approximately $51.9 million. The acquisition
was financed primarily through senior debt . The Lagasse acquisition has been
accounted for using the purchase method of accounting and, accordingly, the
purchase price has been allocated to the assets purchased and the liabilities
assumed based upon the estimated fair values at the date of acquisition with the
excess of cost over fair value of approximately $39.0 million allocated to
goodwill. The financial information for the year ended December 31, 1996
includes the results of Lagasse for two months ended December 31, 1996. The
actual and pro forma effects of this acquisition are not material.
 
2. OPERATIONS
 
    The Company is a national wholesale distributor of business products. The
Company offers approximately 30,000 items from more than 500 manufacturers. This
includes a broad spectrum of office products, computer supplies, office
furniture and facilities management supplies. The Company primarily serves
commercial and contract office products dealers. Its customers include more than
15,000 resellers--such as computer products resellers, office furniture dealers,
mass merchandisers, sanitary supply distributors, warehouse clubs, mail order

of 41 Regional Distribution Centers. Through its integrated computer system, the
Company provides a high level of customer service and overnight delivery. In
addition, the Company has 14 Lagasse Distribution Centers, specifically serving
janitorial and sanitary supply distributors.
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of the Company
and its subsidiaries. All significant intercompany accounts and transactions
have been eliminated in consolidation.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    CASH AND CASH EQUIVALENTS
 
    Investments in low-risk instruments that have original maturities of three
months or less are considered to be cash equivalents. Cash equivalents are
stated at cost which approximates market value.
 
    INVENTORIES
 
    Inventories constituting approximately 94% of total inventories at December
31, 1995 and 1996 have been valued under the last-in, first-out (LIFO) method.
Prior to 1995, all inventories were valued under the first-in, first-out (FIFO)
method. Effective January 1, 1995, Associated changed its method of accounting
for the cost of inventory from the FIFO method to the LIFO method. Associated
made this change in contemplation of its acquisition of United (accounted for as
a reverse acquisition) so that its method would conform to that of United.
Associated believed that the LIFO method provided a better matching of current
costs and current revenues and that earnings reported under the LIFO method were
more easily compared to that of other companies in the wholesale industry where
the LIFO method is common. This change resulted in a charge to pre-tax income of
the Company of approximately $8.8 million ($5.3 million net of tax benefit of
$3.5 million) or $0.37 per common and common equivalent share for the year ended
December 31, 1995. The cumulative effect of this accounting change for years
prior to 1995 is not determinable, nor are the pro forma effects of retroactive
application of the LIFO method to prior years. Inventory valued under the FIFO
and LIFO accounting methods are recorded at the lower of cost or market. If the
lower of FIFO cost or market method of inventory accounting had been used by the
Company for all inventories, merchandise inventories would have been
approximately $8.8 million and $4.8 million higher than reported at December 31,
1995 and 1996, respectively.
 
    PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment is recorded at cost. Depreciation and
amortization are determined by using the straight-line method over the estimated
useful lives of the assets.
 
    The estimated useful life assigned to fixtures and equipment is from two to
ten years; the estimated useful life assigned to buildings does not exceed 40
years; leasehold improvements and assets under capital leases are amortized over
the lesser of their useful lives or the term of the applicable lease.
 
    GOODWILL
 
    Goodwill represents the excess cost over the value of net assets of
businesses acquired and is amortized on a straight-line basis over 40 years. The
Company continually evaluates whether events or circumstances have occurred
indicating that the remaining estimated useful life of goodwill may not be
appropriate. When factors indicate that goodwill should be evaluated for
possible impairment, the Company will use an estimate of undiscounted future
operating income compared to the carrying value of goodwill to determine if a
write-off is necessary. The cumulative amount of goodwill amortized at December
31, 1995 and 1996 is $1,953,000 and $4,047,000, respectively.
 
    SOFTWARE CAPITALIZATION
 
    The Company capitalizes major internal and external systems development
costs determined to have benefits for future periods. Amortization is recognized
over the periods in which the benefits are realized, generally not to exceed
three years.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES
 
    Income taxes are accounted for using the liability method under which
deferred income taxes are recognized for the estimated tax consequences for
temporary differences between the financial statement carrying amounts and the
tax basis of assets and liabilities. Provision has not been made for deferred
U.S. income taxes on the undistributed earnings of the Company's foreign
subsidiaries since these earnings are intended to be permanently invested.
 
    NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE
 
    Net income per common and common equivalent share is based on net income
after preferred stock dividend requirements. Primary and fully diluted earnings
per share are based on the weighted average number of common and common
equivalent shares outstanding during the period. Stock options and warrants are
considered to be common equivalent shares.
 
    FOREIGN CURRENCY TRANSLATION
 
    The functional currency for the Company's foreign operations is the local
currency.
 
    RECLASSIFICATION
 
    Certain amounts from prior periods have been reclassified to conform to the
1996 basis of presentation. During the fourth quarter of 1996, the Company
reclassified certain delivery and occupancy costs from operating expenses to
cost of goods sold to conform the Company's presentation to the presentation
used by others in the business products industry. The following table sets forth
the impact of the reclassification for the years presented in the Consolidated
Statements of Income:

Consolidated Financial Statements and accompanying notes. Actual results could

    NEW ACCOUNTING PRONOUNCEMENTS
 
    During 1996, the Company adopted the supplemental disclosure requirement of
Financial Accounting Standards Board Statement No. 123 (SFAS No. 123),
"Accounting for Stock-Based Compensation." SFAS No. 123 encourages but does not
require adoption of a fair value method of accounting for stock options. For
those entities which do not elect to adopt the fair value method, the new
standard requires supplemental disclosure regarding the pro forma effects of
that method. The Company has chosen to continue to account for stock-based
compensation using the intrinsic value based method of accounting prescribed by
the Accounting Principles Board Opinion No. 25 (APB No. 25), "Accounting for
Stocks Issued to Employees," and related Interpretations. Adoption of SFAS No.
123 will have no impact on the financial position or results of operations of
the Company.
 
    During 1996, the Company adopted Financial Accounting Standards Board
Statement No. 121 (SFAS No. 121), "Accounting for the Impairment of Long-Lived
Assets and Long-Lived Assets to be Disposed Of." SFAS No. 121 requires that an
impairment loss be recorded on long-lived assets used in operations when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the assets' carrying amount. SFAS
No. 121 also addresses the accounting for long-lived assets that are expected to
be disposed. The effect of adoption was not material.

4. BUSINESS COMBINATION AND RESTRUCTURING CHARGE (CONTINUED)
    The historical results for the twelve months ended December 31, 1995 include
a restructuring charge of $9.8 million ($5.9 million net of tax benefit of $3.9
million). The restructuring charge included severance costs totaling $1.8
million. The Company's consolidation plan specified that 330 distribution, sales
and corporate positions, 180 of which related to pre-Merger Associated, were to
be eliminated substantially within one year following the Merger. The Company
has achieved its target, with the related termination costs of approximately
$1.8 million charged against the reserve. The restructuring charge also included
distribution center closing costs totaling $6.7 million and stockkeeping unit
reduction costs totaling $1.3 million. The consolidation plan called for the
closing of eight redundant distribution centers, six of which related to
pre-Merger Associated, and the elimination of overlapping inventory items from
the Company's catalogs substantially within the one-year period following the
Merger. Estimated distribution center closing costs included (i) the net
occupancy costs of leased facilities after they are vacated until expiration of
leases and (ii) the losses on the sale of owned facilities and the facilities'
furniture, fixtures, and equipment. Estimated stockkeeping unit reduction costs
included losses on the sale of inventory items which have been discontinued
solely as a result of the Acquisition. As of December 31, 1996, five of the six
redundant pre-Merger Associated distribution centers have been closed with $5.5
million charged against the reserve and $2.0 million related to stockkeeping
unit reduction costs have also been charged against the reserve. As of December
31, 1996, the Company's consolidation plan has been substantially completed.
Seven of the eight redundant distribution centers have been closed. The
restructuring reserve balance at December 31, 1996 of $0.5 million is expected
to be adequate to cover the remaining estimated expenditures related to
integration and transition costs.
 
    The historical results for 1995 also included an extraordinary charge of
approximately $2.4 million ($1.4 million net of tax benefit of $1.0 million) of
financing costs and original issue discount relating to the debt retired. In
addition, the historical results for 1995 included compensation expense relating
to an increase in the value of employee stock options of approximately $1.5
million ($0.9 million net of tax benefit of $0.6 million) as a result of the
Acquisition and Merger. The pro forma twelve months ended December 31, 1995 do
not include the extraordinary write-off.

    The prevailing prime interest rate at the end of 1995 and 1996 was 8.5% and
8.25%, respectively.
 
    As of December 31, 1996, the credit facilities under the Amended and
Restated Credit Agreement (the "Credit Agreement") consisted of $209.1 million
of term loan borrowings (the "Term Loan Facilities"), and up to $325.0 million
of revolving loan borrowings (the "Revolving Credit Facility"). This agreement
was amended to provide funding for the acquisition of Lagasse Bros., Inc., to
extend the maturities, to adjust the pricing and to revise certain covenants. In
addition, the Company has $150.0 million of 12 3/4% Senior Subordinated Notes
due 2005 (the "Notes").
 
    The Term Loan Facilities consist of a $144.4 million Tranche A term loan
facility (the "Tranche A Facility") and a $64.7 million Tranche B term loan
facility (the "Tranche B Facility"). Quarterly payments under the Tranche A
facility range from $5.63 million at December 31, 1996 to $8.30 million at
September 30, 2001. Quarterly payments under the Tranche B Facility range from
$0.25 million at December 31, 1996 to $6.64 million at September 30, 2003. On
March 31, 1997, principal payments of $15.9 million and $7.4 million are
required to be paid from Excess Cash Flow (as defined in the Credit Agreement)
at December 31, 1996 for the Tranche A and Tranche B Facilities, respectively.
 
    The Revolving Credit Facility is limited to the lesser of $325.0 million or
a borrowing base equal to: 80% of Eligible Receivables (as defined in the Credit
Agreement); plus 50% of Eligible Inventory (as defined in the Credit Agreement)
(provided that no more than 60% or, during certain periods 65%, of the Borrowing
Base may be attributable to Eligible Inventory); plus the aggregate amount of
cover for Letter of Credit Liabilities (as defined in the Credit Agreement). In
addition, for each fiscal year, the Company must repay revolving loans so that
for a period of 30 consecutive days in each fiscal year the aggregate revolving
loans do not exceed $250.0 million. The Revolving Credit Facility matures on
October 31, 2001.
 
    The Term Loan Facilities and the Revolving Credit Facility are secured by
first priority pledges of the stock of USSC, all of the stock of the domestic
direct and indirect subsidiaries of USSC, certain of the

stock of all of the foreign direct and indirect subsidiaries of USSC and
security interests in, and liens upon, all accounts receivable, inventory,
contract rights and other certain personal and certain real property of USSC and
its domestic subsidiaries.
 
    The loans outstanding under the Term Loan Facilities and the Revolving
Credit Facility bear interest as determined within a set range with the rate
based on the ratio of total debt to earnings before interest, taxes,
depreciation and amortization ("EBITDA"). The Tranche A Facility and the
Revolving Credit Facility bear interest, at prime plus 0.25% to 1.25% or, at the
Company's option, LIBOR plus 1.50% to 2.50%. The Tranche B Facility bears
interest at prime plus 1.25% to 1.75% or, at the Company's option, LIBOR plus
2.50% to 3.00%.
 
    The Credit Agreement contains representations and warranties, affirmative
and negative covenants and events of default customary for financings of this
type. As of December 31, 1996, the Company was in compliance with all covenants
contained in the Credit Agreement.
 
    The Company is exposed to market risk for changes in interest rates. The
Company may enter into interest rate protection agreements, including collar
agreements, to reduce the impact of fluctuations in interest rates on a portion
of its variable rate debt. Such agreements generally require the Company to pay
to or entitle the Company to receive from the other party the amount, if any, by
which the Company's interest payments fluctuate beyond the rates specified in
the agreements. The Company is subject to the credit risk that the other party
may fail to perform under such agreements. The Company's allocated cost of such
agreements is amortized to interest expense over the term of the agreements, and
the unamortized cost is included in other assets. Payments received or made as a
result of the agreements, if any, are recorded as an addition or a reduction to
interest expense. At December 31, 1996, the Company had agreements which collar
$200.0 million of the Company's borrowings under the Credit Facilities at
interest rates between 8.0% and 6.0%, which expire in April 1998. For the years
ended December 31, 1995 and 1996, the Company recorded $0.1 million and $0.9
million, respectively, to interest expense resulting from interest rate
fluctuations beyond the rates specified in the collar agreements.
 
    The right of United to participate in any distribution of earnings or assets
of USSC is subject to the prior claims of the creditors of USSC. In addition,
the Credit Agreement contains certain restrictive covenants, including covenants
that restrict or prohibit USSC's ability to pay dividends and make other
distributions to United.

7. PENSION PLANS AND DEFINED CONTRIBUTION PLAN
 
    PENSION PLANS
 
    In connection with the Merger and Acquisition, the Company assumed the
pension plans of United. Associated did not have a pension plan. Former
Associated employees entered the pension plans on July 1, 1996. As of this date,
the Company has pension plans covering substantially all of its employees. Non-
contributory plans covering non-union employees provide pension benefits that
are based on years of credited service and a percentage of annual compensation.
Non-contributory plans covering union members generally provide benefits of
stated amounts based on years of service. The Company funds the plans in
accordance with current tax laws.

    DEFINED CONTRIBUTION
 
    The Company has a defined contribution plan in which all salaried employees
and certain hourly paid employees of the Company are eligible to participate
following completion of six consecutive months of employment. The plan permits
employees to have contributions made as 401(k) salary deferrals on their behalf,
or as voluntary after-tax contributions, and provides for Company contributions,
or contributions

matching employee salary deferral contributions, at the discretion of the Board
of Directors. The Company has no present intention to make Company contributions
other than matching contributions. Company contributions for matching of
employee contributions were approximately $0.3 million, $0.6 million and $0.9
million in 1994, 1995 and 1996, respectively.
 
8. POSTRETIREMENT BENEFITS
 
    In connection with the Merger, the Company assumed the postretirement plan
of United on March 30, 1995. Associated did not have a postretirement plan. The
plan is unfunded and provides health care benefits to substantially all retired
non-union employees and their dependents. Eligibility requirements are based on
the individual's age (minimum age of 55), years of service and hire date. The
benefits are subject to retiree contributions, deductibles, co-payment
provisions and other limitations. Retirees pay one-half of the projected plan
costs.

9. STOCK OPTION PLAN
 
    The Management Equity Plan (the "Plan"), as amended, is administered by the
Board of Directors, although the Plan provides that the Board of Directors of
the Company may designate an option committee to administer the Plan.
 
    In September 1995, the Company's Board of Directors approved an amendment to
the Plan which provided for the issuance of options to key management employees
of the Company exercisable for up to 2.2 million additional shares of its Common
Stock. Subsequently, approximately 2.2 million options were granted during 1995
and 1996 to management employees. Some of the options were granted at an option
price below market value and the option price of certain options increases by
$0.625 on a quarterly basis effective April 1, 1996.
 
    The stock options granted under the Plan do not vest to the employee until
the occurrence of an event (a "Vesting Event") that causes the present
non-public equity investors to have received at least a full return of their
investment (at cost) in cash, fully tradable marketable securities or the
equivalent. A Vesting Event will cause the Company to recognize compensation
expense based upon the difference between the fair market value of the Common
Stock and the exercise prices of the stock options. If a Vesting Event were to
occur, based upon a stock price of $19.50, the Company would recognize a
nonrecurring noncash charge of $18.4 million in compensation expense ($10.6
million net of tax benefit of $7.8 million). Each $1.00 change in the fair
market value of Common Stock could result in a maximum adjustment to such
compensation expense of approximately $2.5 million ($1.4 million net of tax
effect of $1.1 million).
 
    An optionee under the Plan must pay the full option price upon exercise of
an option (i) in cash, (ii) with the consent of the Board of Directors of the
Company, by delivering shares of Common Stock already owned by such optionee
(including shares to be received upon exercise of the option) and having a fair
market value at least equal to the exercise price or (iii) in any combination of
the foregoing. The Company may require the optionee to satisfy federal tax
withholding obligations with respect to the exercise of options by (i)
additional withholding from the employee's salary, (ii) requiring the optionee
pay in cash or (iii) reducing the number of shares of Common Stock to be issued
(except in the case of incentive options).
 
    The following table summarizes the transactions of the Plan for the last
three years:

    All share and per share data have been restated to reflect the 100% stock
dividend effective November 9, 1995 and the conversion of Associated common
stock as a result of the Merger.
 
    During 1996, the Company adopted the supplemental disclosure requirements of
SFAS No. 123. Accordingly, the Company is required to disclose pro forma net
income and earnings per share as if the fair value-based accounting method in
SFAS No. 123 had been used to account for stock-based compensation cost. The
Company's stock options granted under the Plan are considered "all or nothing"
awards since the options do not vest to the employee until the occurrence of a
Vesting Event. The fair value of "all or nothing" awards are measured at the
grant date; however, amortization of compensation expense only begins when it is
probable that the awards will vest and be earned. Presently, the Company
believes that it is less than likely that a Vesting Event will occur. Therefore,
there is no compensation expense for pro forma purposes and pro forma net income
and earnings per share are the same as that recorded on the face of the income
statement.
 
    The Company uses a binomial option pricing model to estimate the fair value
of options at the date of grant. The weighted average assumptions used to value
options and the weighted average fair value of options granted during 1995 and
1996 were as follows:

thereof to buy shares of Common Stock at an exercise price of $0.10 per share.

exercise of the put rights is the greater of the then fair market value or
equity value of the warrants, as defined, less the applicable exercise price of
the warrants. Payment of the Lender Warrants can only occur after repayment of
all debt outstanding under the Credit Agreement or with the consent of the
lenders and/or agent under the Credit Agreement.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION
 
    The accompanying condensed consolidated financial statements are unaudited,
except for the Consolidated Balance Sheet as of December 31, 1996. These
financial statements have been prepared in accordance with the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations. In the opinion of the Company's
management, the condensed consolidated financial statements for the unaudited
interim periods presented include all adjustments necessary to fairly present
the results of such interim periods and the financial position as of the end of
said periods. These adjustments were of a normal recurring nature and did not
have a material impact on the financial statements presented. Certain interim
expense and inventory estimates are recognized throughout the fiscal year
relating to marginal income tax rates, shrinkage, price changes and product mix.
Any refinements to these estimates based on actual experience are recorded when
known.
 
    On October 31, 1996, the Company acquired all of the capital stock of
Lagasse Bros., Inc. ("Lagasse") for approximately $51.9 million. The acquisition
was financed primarily through senior debt. The Lagasse acquisition has been
accounted for using the purchase method of accounting and, accordingly, the
purchase price has been allocated to the assets purchased and the liabilities
assumed based upon the estimated fair values at the date of acquisition with the
excess of cost over fair value of approximately $39.0 million allocated to
goodwill. The financial information for the six-month period ended June 30, 1997
includes the results of Lagasse. The actual and pro forma effects of this
acquisition are not material.
 
2. OPERATIONS
 
    The Company is a national wholesale distributor of business products. The
Company offers approximately 30,000 items from more than 500 manufacturers. This
includes a broad spectrum of office products, computer supplies, office
furniture and facilities management supplies. The Company primarily serves
commercial and contract office products dealers. Its customers include more than
15,000 resellers-- such as computer products resellers, office furniture
dealers, mass merchandisers, sanitary supply distributors, warehouse clubs, mail
order houses and office products superstores. The Company has a distribution
network of 41 Regional Distribution Centers. Through its integrated computer
system, the Company provides a high level of customer service and overnight
delivery. In addition, the Company has 14 Lagasse Distribution Centers,
specifically serving janitorial and sanitary supply distributors.
 
3. RECLASSIFICATION
 
    Certain amounts from prior periods have been reclassified to conform to the
1997 basis of presentation. During the fourth quarter of 1996, the Company
reclassified certain delivery and occupancy costs from operating expenses to
cost of goods sold to conform the Company's presentation to the presentation

used by others in the business products industry. The following table sets forth
the impact of the reclassification:

<S>                                                                        <C>
Gross Margin as a Percent of Net Sales:
  Gross margin prior to the reclassification.............................             21.0%
  Gross margin as reported herein........................................             16.9%
Operating Expenses as a Percent of Net Sales:
  Operating expense ratio prior to reclassification......................             16.3%
  Operating expense ratio as reported herein.............................             12.2%
</TABLE>
 
4. REDEEMABLE WARRANTS
 
    The Redeemable Warrants reflected on the Consolidated Balance Sheets are
adjusted on an ongoing basis for any exercises to Common Stock, revaluation
based on the current market value of the Company's Common Stock and any issuance
of Warrants to counter the dilutive impact resulting from the issuance of other
common stock equivalents such as the issuance of stock options by the Company.
 
5. STOCK OPTION PLAN
 
    Employee stock options granted under the Company's employee stock option
plan do not vest to the employee until the occurrence of an event (a "Vesting
Event") that causes certain non-public equity investors to have received at
least a full return of their investment (at cost) in cash, fully tradable
marketable securities or the equivalent. A Vesting Event will cause the Company
to recognize compensation expense based upon the difference between the fair
market value of the Company's common stock and the exercise price of the
employee stock options. Based upon a stock price of $25.25 and options
outstanding as of June 30, 1997, the Company would recognize a nonrecurring
noncash pre-tax charge of $28.8 million in compensation expense if a Vesting
Event were to occur. Each $1.00 change in the fair market value of common stock
could result in a maximum pre-tax adjustment to such compensation expense of
approximately $2.4 million.
 
6. NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE
 
    Net income per common and common equivalent share is based on net income
after preferred stock dividend requirements. Net income per common and common
equivalent share for the six months ended June 30, 1997 and 1996 on a primary
and fully diluted basis are computed using the weighted average number of shares
outstanding adjusted for the effect of stock options and warrants considered to
be dilutive common stock equivalents.
 
7. NEW ACCOUNTING PRONOUNCEMENT
 
    In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings per Share, which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method currently
used to compute earnings per share and to restate all prior periods presented to
conform to the new method. Under the new requirements for calculating primary
earnings

7. NEW ACCOUNTING PRONOUNCEMENT (CONTINUED)
per share, the dilutive effect of common stock equivalents will be excluded. The
impact is expected to result in an increase in primary earnings per share of
$0.19 and $0.25 for the six-month periods ended June 30, 1996 and 1997,
respectively. The impact of Statement No. 128 on the calculation of fully
diluted earnings per share for these periods is not expected to be material.

consolidated financial statements based on our audits.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated 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 audit provide a reasonable
basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the results of operations and cash
flows of United Stationers Inc. and Subsidiaries for the fiscal year ended
August 31, 1994, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  SUBSEQUENT EVENT
 
    On March 30, 1995, Associated Holdings, Inc. ("Associated") purchased 92.5%
of the then outstanding shares of the common stock, $0.10 par value ("Common
Stock") of United Stationers Inc. ("United") for approximately $266.6 million in
the aggregate pursuant to a tender offer (the "Tender Offer"). Immediately
thereafter, Associated merged with and into United (the "Merger" and,
collectively with the Tender Offer, the "Acquisition"), and Associated
Stationers, Inc., a wholly-owned subsidiary of Associated ("ASI") merged with
and into United Stationers Supply Co., a wholly-owned subsidiary of United
("USSC"), with United and USSC continuing as the respective surviving
corporations. United, as the surviving corporation following the Merger, is
referred to herein as the "Company". As a result of share conversions in the
Merger, immediately after the Merger, (i) the former holders of common stock and
common stock equivalents of Associated owned shares of Common Stock and warrants
or options to purchase shares of Common Stock constituting in the aggregate
approximately 80% of the shares of Common Stock on a fully diluted basis, and
(ii) holder of pre-Merger United common stock owned in the aggregate
approximately 20% of the shares of Common Stock on a fully diluted basis.
Although United was the surviving corporation in the Merger, the transaction was
treated as a reverse acquisition for accounting purposes with Associated as the
acquiring corporation.
 
    Immediately following the Merger, the number of outstanding Shares was
5,998,117 (or 6,973,720 on a fully diluted basis), of which (i) the former
holders of Class A Common Stock, $0.01 par value, and Class B Common Stock,
$0.01 par value, of Associated ("Associated Common Stock") and warrants or
options to purchase Associated Common Stock in the aggregate owned 4,603,373
Shares constituting approximately 76.8% of the outstanding Shares and
outstanding warrants or options for 975,603 Shares (collectively 80.0% on a
fully diluted basis) and (ii) pre-Merger holders of Shares (other than
Associated-owned Shares and treasury Shares) in the aggregate owned 1,394,744
Shares constituting approximately 23.2% of the outstanding Shares (or 20.0% on a
fully diluted basis). As used in this paragraph, the term "Shares" includes
shares of Nonvoting Common Stock, $0.01 par value, of the Company, which are
immediately convertible into Shares for no additional consideration.
 
    To finance the Offer, refinance existing debt of ASI, the Company and USSC,
repurchase stock options and pay related fees and expenses, Associated, ASI,
USSC and the Company entered into (i) new credit facilities ("New Credit
Facilities") with a group of banks and financial institutions providing for term
loan borrowings of $200.0 million and revolving loan borrowings of up to $300.0
million and (ii) a senior subordinated bridge loan facility in the aggregate
principal amount of $130.0 million (the "Subordinated Bridge Facility"). In
addition, simultaneously with the consummation of the Offer, Associated obtained
$12.0 million from the sale of additional shares of Associated Common Stock,
which proceeds were used to finance the purchase of a portion of the Shares
pursuant to the Offer.
 
    On May 3, 1995, USSC completed the issuance of $150.0 million of 12 3/4%
Senior Subordinated Notes (the "Notes") due 2005. The net proceeds of the Notes
(after discount and fees of approximately $5.5 million) were used to pay certain
expenses, to repay the $130.0 million Subordinated Bridge Facility (together
with $1.6 million in accrued and unpaid interest thereon), to repay a portion of
the Tranche A and Tranche B term loans (totaling approximately $6.5 million) and
provide working capital. In the event the necessary consents are obtained, the
Company expects to repurchase the Series B Preferred Stock, together with
accrued and unpaid dividends thereon (approximately $7.0 million).
 
    The New Credit Facilities contain certain financial covenants covering the
Company and its subsidiaries on a consolidated basis, including, without
limitation, covenants relating to tangible net worth, capitalization, fixed
charge coverage, capital expenditures and payment of dividends by the Company.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1.  SUBSEQUENT EVENT (CONTINUED)
    Effective for 1995, the Company changed its fiscal year from a year end of
August 31 to December 31. The financial statements included herein represent the
final financial statements of the Company through the date of the consummation
of the Merger. Future financial statements of the Company will reflect
Associated and its acquisition of the Company, and will be on the basis of a
December 31 fiscal year end.
 
    As part of the Merger, the Company incurred approximately $27.8 million of
merger-related costs. The amount consisted of severance payments under
employment contracts ($9.6 million); insurance benefits under employment
contracts ($7.4 million); legal, accounting and other professional services fees
($5.2 million); retirement of stock options ($3.0 million); and fees for letters
of credit related to employment contracts and other costs ($2.6 million).
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of United
Stationers Inc. and its wholly owned subsidiaries (the Company). Investments in
20% to 50% owned companies are accounted for by the equity method. All
significant intercompany accounts and transactions have been eliminated in
consolidation. Certain prior-year amounts have been reclassified to conform with
current-year presentations.
 
    REVENUE RECOGNITION
 
    Sales and provisions for estimated sales returns and allowances are recorded
at the time of shipment.
 
    CASH AND CASH EQUIVALENTS
 
    Investments in low-risk instruments which have an original maturity of three
months or less are considered to be cash equivalents. Cash equivalents are
stated at cost which approximates market value. The Company's cash equivalent
policy conforms to the requirements of Financial Accounting Standard No. 95.
 
    INVENTORIES
 
    Inventories constituting approximately 82% of total inventories at August
31, 1993, August 31, 1994 and March 30, 1995 have been valued under the last-in,
first-out (LIFO) method with the remainder of the inventory valued under the
first-in, first-out (FIFO) method. Inventory valued under the FIFO and LIFO
accounting methods are recorded at the lower of cost or market.
 
    In 1994, liquidations of certain LIFO inventories had the effect of
increasing net earnings by $830,000 or $0.04 per share.
 
    DEPRECIATION AND AMORTIZATION
 
    Depreciation and amortization are determined by using the straight-line
method over the estimated useful lives of the assets.
 
    The estimated useful life assigned to fixtures and equipment is from two to
10 years; the estimated useful life assigned to buildings does not exceed 40
years; leasehold improvements and assets under capital leases are amortized over
the lesser of their useful lives or the term of the applicable lease.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Goodwill reflecting the excess of cost over the value of net assets of
businesses acquired is being amortized on a straight-line basis over 40 years.
 
    SOFTWARE CAPITALIZATION
 
    The Company capitalizes major internal and external systems development
costs determined to have benefits for future periods. Amortization expense is
recognized over the periods in which the benefits are realized, generally not to
exceed three years. Amortization expense was $2,376,000 and $1,795,000 in 1994
and 1995, respectively.
 
    FOREIGN CURRENCY TRANSLATION
 
    All assets and liabilities of the Company's foreign operations are
translated at current exchange rates. Revenues and expenses are translated at
average exchange rates for the year in accordance with Statement of Financial
Accounting Standard No. 52. The amounts for all years presented were immaterial.
 
    EARNINGS PER SHARE
 
    Earnings per share and the effect on earnings per share of potentially
dilutive stock options are computed by the treasury stock method. This
computation takes into account the weighted average number of shares outstanding
during each year, outstanding stock options and their exercise prices, and the
market price of the stock throughout the year. The exercise of outstanding stock
options would not result in a material dilution of earnings per share.
 
    RECLASSIFICATION
 
    The Consolidated Statements of Operations reflect a reclassification of
certain delivery and occupancy costs from operating expense to cost of goods
sold to conform the Company's presentation used by others in the business
products industry. The following table sets forth the impact of the
reclassification for the years presented in the Consolidated Statements of
Operations:

percentage of annual compensation. Non-contributory plans covering union members
generally provide benefits of stated amounts based on years of service. The
Company funds the plans in accordance with current tax laws.
 
    The Company also has a non-contributory, non-qualified plan ("Supplemental
Benefits Plan") in effect for certain executives. The Company has not funded
this plan.
 
    Net periodic pension cost for 1994 and 1995 for pension and supplemental
benefits plans includes the following components (in thousands of dollars):

    The projected benefit obligations for 1994 and 1995 were determined using an
assumed discount rate of 7.5%. The assumed rate of compensation increase ranged
from 0% to 5.5% and the expected long-term rate of return on assets used in
determining net periodic pension cost was 7.5%.
 
    The Company provides an unfunded health care plan to substantially all
retired non-union employees and their dependents. Eligibility requirements are
based on the individual's age (minimum age of 55), years of service and hire
date. The benefits are subject to retiree contributions, deductibles, co-payment
provisions and other limitations.
 
    During the first quarter of 1994, the Company adopted Statement of Financial
Accounting Standard No. 106 (SFAS 106), "Employer's Accounting for
Postretirement Benefits Other Than Pensions". SFAS 106 requires companies to
accrue the expected cost of postretirement health care and life insurance
benefits throughout the employee's active service period. Previously,
postretirement health care costs were recognized as claims were paid. The
Company elected to amortize the unfunded Accumulated Postretirement Benefit
Obligation (APBO) over 20 years.
 
    The assumed health care average cost trend rate used in measuring the APBO
at March 30, 1995 was 11.0% in 1995 and 3% in 1996 and beyond. Beginning in
1996, retirees will pay the difference between actual plan costs and the portion
of cost paid by the Company which is limited to a cost trend rate of 3%. The
assumed discount rate was 7.75%. A 1% increase in the care cost trend rate would
increase the APBO as of March 30, 1995 by approximately $339,000 and the sum of
the 1995 annual service cost and interest cost by approximately $35,000.
 
    The cost of postretirement health care benefits for the year ended August
31, 1994 and seven months ended March 30, 1995 are as follows (in thousands of
dollars):

3.  PENSION PLANS AND POSTRETIREMENT BENEFITS (CONTINUED)
    The Company has a qualified Profit Sharing Plan in which all salaried
employees and certain hourly paid employees of the Company are eligible to
participate upon completion of six consecutive months of employment. The Profit
Sharing Plan provides for annual contributions by the Company in an amount
determined by the Board of Directors. The Plan also permits employees to have
contributions made as 401(k) salary deferrals on their behalf and to make
after-tax voluntary contributions. The Plan provides that the Company may match
employee contributions as 401(k) salary deferrals. Company contributions to the
Plan for both profit sharing and matching of employee contributions were
approximately $0.5 million in 1994 and $0.8 million in 1995.
 
4.  STOCK INCENTIVE PLANS
 
    As a result of the change in control of the Company, the Company paid out
approximately $3.0 million to option holders representing the difference between
the tender offer price of the stock ($15.50 per share) and the option exercise
price. The amount was included in merger-related costs in 1995.
 
    Under the Directors' Stock Option Plan, the Company granted options for
7,500 shares at a price of $15.25 per share in 1994 and 7,500 shares at a price
of $13.75 per share in 1995. The Directors' Option Plan provides for the
granting of options covering up to 100,000 shares of the Company's common stock,
subject to anti-dilution adjustments. Options are exercisable at any time after
they are granted, but for not more than ten years after the option's grant. As
of the period ended 1994 and 1995, 41,000 and 0 options were outstanding,
respectively.
 
    During fiscal 1995, options for a total of 100,000 shares at $10.50 were
granted to certain officers. The grant was approved at the 1995 Annual Meeting
held in January. Under the Company's 1981 Stock Incentive Award Plan, options
outstanding had an exercisable life of either five, six or ten years from the
date of grant. The Company granted certain officers 16,700 and 15,000 shares of
restricted stock in 1991 and 1992, respectively. There have been no restricted
stock grants since 1992. The grants of restricted shares resulted in deferred
compensation expense of $699,000 of which $185,000, $132,000, $39,000 and
$16,000 was recognized in 1992, 1993, 1994 and 1995, respectively. The
unrecognized portion of deferred compensation was $55,000, $16,000 and $0 as of
August 31, 1993, August 31, 1994 and March 30, 1995, respectively. Under the
terms of the grant, the stock does not vest to the employee until completion of
three years of employment after the date of grant. The 1981 Stock Incentive
Award Plan was terminated by the Company's Board of Directors on March 30, 1995.
 
    In 1989, the Board of Directors terminated the 1985 Non-qualified Stock
Option Plan so that no further stock options would be issued under this plan.
The termination of the plan did not affect the options previously granted and
outstanding. No option could have been exercised more than ten years after its
grant.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The Charter and Restated Bylaws of the Company provide for the
indemnification of directors and officers to the fullest extent permitted by the
General Corporation Law of the State of Delaware ("DGCL"). Pursuant to the
provisions of Section 145 of the DGCL, the Company has the power to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit, or proceeding (other than an
action by or in the right of the Company) by reason of the fact that he is or
was a director, officer, employee, or agent of the Company against any and all
expenses, judgments, fines, and amounts paid in settlement actually and
reasonably incurred in connection with such action, suit, or proceeding. The
power to indemnify applies only if such person acted in good faith and in a
manner he reasonably believed to be in the best interest, or not opposed to the
best interest, of the Company and with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.
 
    Indemnification is not available if such person has been adjudged to have
been liable to the Company, unless and only to the extent the court in which
such action was brought determines that, despite the adjudication of liability,
but in view of all the circumstances, the person is reasonably and fairly
entitled to indemnification for such expenses as the court shall deem proper.
The Company has the power to purchase and maintain insurance for such persons.
The statutes also expressly provide that the power to indemnify authorized
thereby is not exclusive of any rights granted under any bylaw, agreement, vote
of stockholders or disinterested directors, or otherwise.
 
    The above discussion of the Charter and Restated Bylaws of the Company and
of Section 145 of the DGCL is not intended to be exhaustive and is qualified in
its entirety by such Charter and Restated Bylaws of the Company and the DGCL.
 
    The Company also carries director and officer liability insurance policies.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Commission, such indemnification is against public
 
                                      II-1
<PAGE>
policy as expressed in the Securities Act and is therefore unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer, or
controlling person thereof in the successful defense of any action, suit or
proceeding) is asserted by a director, officer, or controlling person in
connection with the securities being registered, the Company will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

     1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company 
represents and warrants to, and agrees with, the several Underwriters that:

          (a)  The Company has filed with the Securities and Exchange 
Commission (the "COMMISSION") a registration statement, and may have filed an 
amendment or amendments thereto, on Form S-2 (No. 333-_________________), for 
the registration of the Shares and the Warrants under the Securities Act of 
1933, as amended (the "ACT").  The Company will not, without the prior 
consent of the Representatives, file any amendment thereto or make any change 
in the form of final prospectus included therein.  Such registration 
statement, including the prospectus, financial statements and schedules, 
exhibits and all other documents filed as a part thereof, at the time of 
effectiveness of the registration statement, including any information to be 
a part thereof as of the time of effectiveness pursuant to paragraph (b) of 
Rule 430A or Rule 434 of the rules and regulations of the Commission under 
the Act (the "REGULATIONS"), is herein called the "REGISTRATION STATEMENT" 
and the prospectus, in the form first filed with the Commission pursuant to 
Rule 424(b) of the Regulations or filed as part of the Registration Statement 
at the time of effectiveness if no Rule 424(b) or Rule 434 filing is 
required, is herein called the "PROSPECTUS." The term "PRELIMINARY 
PROSPECTUS" as used herein means a preliminary prospectus as described in 
Rule 430 of the Regulations.  If the Company has filed an abbreviated 
registration statement to register additional shares of Common Stock pursuant 
to Rule 462 of the Regulations (the "RULE 462 REGISTRATION STATEMENT"), then 
any reference herein to the term "REGISTRATION STATEMENT" shall be deemed to 
include such Rule 462 Registration Statement.  Any reference herein to the 
Registration Statement, any preliminary prospectus or the Prospectus shall be 
deemed to refer to and include the documents incorporated by reference 
therein pursuant to Item 12 of Form S-2 which were filed under the Securities 
Exchange Act of 1934, as amended (the "EXCHANGE ACT"), on or before the 
effective date of the Registration Statement, the date of such preliminary 
prospectus or the date of the Prospectus, as the case may be, and any 
reference herein to the terms "AMEND," "AMENDMENT" or "SUPPLEMENT" with 
respect to the Registration Statement, any preliminary prospectus or the 
Prospectus shall be deemed to refer to and include (i) the filing of any 
document under the Exchange Act after the effective date of the Registration 
Statement, the date of such preliminary prospectus or the date of the 
Prospectus, as the case may be, which is incorporated therein by reference 
and (ii) any such document so filed.

          (b)  At the time of the effectiveness of the Registration Statement 
or the effectiveness of any post-effective amendment to the Registration 
Statement, when the Prospectus is first filed with the Commission pursuant to 
Rule 424(b) or Rule 434 of the Regulations, when any supplement to or 
amendment of the Prospectus is filed with the Commission and at the Closing 
Date and the Additional Closing Date, if any (as hereinafter respectively 
defined), the Registration Statement and the Prospectus and any amendments 
thereof and supplement thereto complied or will comply in all material 
respects with the applicable provisions of the Act and the Exchange Act and 
the respective rules and

                                          2
<PAGE>

regulations thereunder and does not or will not contain an untrue statement 
of a material fact and does not or will not omit to state any material fact 
required to be stated therein or necessary in order to make the statements 
therein (i) in the case of the Registration Statement, not misleading and 
(ii) in the case of the Prospectus, in light of the circumstances under which 
they were made, not misleading.  When any related preliminary prospectus was 
first filed with the Commission (whether filed as part of the registration 
statement for the registration of the Shares and the Warrants or any 
amendment thereto or pursuant to Rule 424(a) of the Regulations) and when any 
amendment thereof or supplement thereto was first filed with the Commission, 
such preliminary prospectus and any amendments thereof and supplements 
thereto complied in all material respects with the applicable provisions of 
the Act and the Exchange Act and the respective rules and regulations 
thereunder and did not contain an untrue statement of a material fact and did 
not omit to state any material fact required to be stated therein or 
necessary in order to make the statements therein in light of the 
circumstance under which they were made not misleading.  No representation 
and warranty is made in this subsection (b), however, with respect to any 
information contained in or omitted from the Registration Statement or the 
Prospectus or any related preliminary prospectus or any amendment thereof or 
supplement thereto in reliance upon and in conformity with information 
furnished in writing to the Company by or on behalf of any Underwriter 
through the Representatives as herein stated expressly for use in connection 
with the preparation thereof.  If Rule 434 is used, the Company will comply 
with the requirements of Rule 434.

          (c)  Neither the Commission nor the "Blue Sky" or securities 
authority of any jurisdiction has issued an order (a "STOP ORDER") suspending 
the effectiveness of the Registration Statement, preventing or suspending the 
use of any preliminary prospectus, the Prospectus, the Registration Statement 
or any amendment or supplement thereto, refusing to permit the effectiveness 
of the Registration Statement, or suspending the registration or 
qualification of the Firm Shares or the Additional Shares, nor, to the best 
knowledge of the Company, has any of such authorities instituted or 
threatened to institute any proceedings with respect to a Stop Order.

          (d)  Each of Ernst & Young LLP and Arthur Andersen LLP, whose 
reports are filed with the Commission as a part of the Registration 
Statement, are independent public accountants with regard to the Company and 
Associated Holdings, Inc. ("ASSOCIATED") and each of their respective 
subsidiaries as required by the Act and the Regulations.

          (e)  Subsequent to the respective dates as of which information is 
given in the Registration Statement and the Prospectus, except as set forth 
in the Registration Statement and the Prospectus, there has been no material 
adverse change or any development involving a prospective material adverse 
change in the business, prospects, properties, operations, condition 
(financial or other) or results of operations of the Company and its 
subsidiaries taken as a whole, whether or not arising from transactions in 
the ordinary course of business, and since the date of the latest balance 
sheet presented in the Registration Statement and the Prospectus, neither the 
Company nor any of its subsidiaries has incurred or undertaken any 
liabilities or obligations, direct or contingent, which are material to the 
Company and its subsidiaries taken as a whole, except for liabilities or 
obligations which are reflected in the Registration Statement and the 
Prospectus.

          (f)  The Company and United Stationers Supply Co., an Illinois 
corporation and the principal operating subsidiary of the Company ("USSC"), 
have the corporate power and the authority to enter into this Agreement, 
perform each of their respective obligations hereunder and, with respect to 
the Company, to issue, sell and deliver the Shares to be sold by it 
hereunder.  This Agreement and the transactions contemplated herein have been 
duly and validly authorized by the Company and USSC and this Agreement has 
been duly and validly executed and delivered by the Company and USSC and is a 
valid and binding obligation of the Company and USSC, enforceable against 
each in accordance with its terms, except (i) as the enforceability thereof 
may be limited by bankruptcy, insolvency, fraudulent conveyance, 
reorganization, moratorium or other similar laws affecting the enforcement of 
creditors' rights generally and by general equitable principles and (ii) to 
the extent that rights to indemnity hereunder may be limited by federal or 
state securities laws or the public policy underlying such laws.

          (g)  The execution, delivery and performance of this Agreement and 
the consummation of the transactions contemplated hereby do not and will not 
(i) conflict with or result in a breach of any of the terms and provisions 
of, or constitute a default (or an event which with notice or lapse of time, 
or both, would constitute a default) or require consent under, or result in 
the creation or imposition of any lien, charge or encumbrance upon any 
property or assets of the Company or any of its subsidiaries, pursuant to the 
terms of any agreement, instrument, franchise, license or permit to which the 
Company or any of its subsidiaries is a party or by which any of such 
corporations or their respective properties or assets may be bound or (ii) 
violate or conflict with any provision of the certificate of incorporation or 
bylaws of the Company or any of its subsidiaries or any judgment, decree, 
order, statute, rule or regulation of any court or any public, governmental 
or regulatory agency or body having jurisdiction over the Company or any of 
its subsidiaries or any of their respective properties or assets.  No 
consent, approval, authorization, order, registration, filing, qualification, 
license or permit of or with any court or any public, governmental or 
regulatory agency or body having jurisdiction over the Company or any of its 
subsidiaries or any of their respective properties or assets is required for 
the execution, delivery and performance of this Agreement or the consummation 
of the transactions contemplated hereby, including the issuance, sale and 
delivery of the Shares to be issued, sold and delivered by the Company 
hereunder, except the registration under the Act of the Shares and the 
Warrants and such consents, approvals, authorizations, orders, registrations, 
filings, qualifications, licenses and permits as may be required under state 
securities or Blue Sky laws in connection with the purchase and distribution 
of the Shares by the Underwriters, all of which have been obtained as of the 
date hereof.

          (h)  All of the outstanding shares of Common Stock are duly and 
validly authorized and issued, are fully paid and nonassessable and were not 
issued and are not now in violation of or subject to any preemptive or 
similar rights.  The Company had, at September ___, 1997, an authorized and 
outstanding capitalization as set forth in the Registration Statement and the 
Prospectus.  The Shares, when issued, delivered and sold in accordance with 
this Agreement, will be duly and validly issued and outstanding, fully paid 
and nonassessable, and will not have been issued in violation of or be 
subject to any preemptive or similar rights.  The Common Stock conforms to 
the description thereof contained in the Registration Statement and the 
Prospectus.

                                          4

          (i)  The Warrants have been duly and validly authorized and issued 
and were not issued in violation of or subject to any preemptive or similar 
rights. The Warrants represent the valid and binding obligation of the 
Company, enforceable in accordance with their terms.  The Shares to be issued 
upon the exercise of the Warrants (i) will be duly and validly authorized and 
issued and fully paid and nonassessable, (ii) will not be issued in violation 
of or subject to any preemptive or similar rights, and (iii) will be free of 
any further restrictions under the terms of any warrant agreement, warrant or 
other instrument relating thereto.  The Warrants are freely transferable by 
the Selling Stockholders to the Underwriters in accordance with the 
transactions contemplated by this Agreement.

          (j)  Each of the Company and its subsidiaries has been duly 
organized and is validly existing as a corporation in good standing under the 
laws of its jurisdiction of incorporation.  Each of the Company and its 
subsidiaries is duly qualified and in good standing as a foreign corporation 
in each jurisdiction in which the character or location of its properties 
(owned, leased or licensed) or the nature or conduct of its business makes 
such qualification necessary, except for those failures to be so qualified or 
in good standing which will not in the aggregate have a material adverse 
effect on the Company and its subsidiaries taken as a whole.  Each of the 
Company and its subsidiaries has all requisite power and authority, and all 
necessary consents, approvals, authorizations, orders, registrations, 
qualifications, licenses and permits of and from all public, regulatory or 
governmental agencies and bodies, to own, lease and operate its properties 
and conduct its business as now being conducted and as described in the 
Registration Statement and the Prospectus, and no such consent, approval, 
authorization, order, registration, qualification, license or permit contains 
a materially burdensome restriction not adequately disclosed in the 
Registration Statement and the Prospectus.

          (k)  As of September ____, 1997 and as of the date hereof, USSC was 
the Company's only significant subsidiary (as defined in the Regulations).  
All of the outstanding shares of capital stock of USSC have been duly and 
validly issued, are fully paid and nonassessable and were not issued in 
violation of preemptive rights, repurchase rights or rights of first refusal 
and are owned directly by the Company free and clear of any lien, pledge, 
encumbrance, claim, security interest, restriction on transfer, stockholders' 
agreement, voting trust or other defect of title whatsoever other than the 
pledge of such shares to The Chase Manhattan Bank, as collateral agent under 
the Company's senior secured credit agreement.

          (l)  Except as described in the Registration Statement and as shall 
be described in the Prospectus, there is no litigation, action, suit, 
investigation or proceeding, governmental or otherwise, to which the Company 
or any of its subsidiaries is a party or to which any property of the Company 
or any of its subsidiaries is subject or which is pending or, to the best 
knowledge of the Company, comtemplated against the Company or any of its 
subsidiaries which (i) might result in any material adverse change or any 
development involving a material adverse change in the business, prospects, 
properties, assets, earnings, operations, condition (financial or other) or 
results of operations of the Company and its subsidiaries taken as a whole, 
(ii) is required to be disclosed in the Registration Statement and the 
Prospectus, or (iii) seeks to restrain, enjoin, prevent the consummation of, 
or otherwise challenge the issuance of, the Shares or the execution and 
delivery of this Agreement or any of the other transactions contemplated 
hereby, or questions the legality

                                          5
<PAGE>

or validity of any such transactions or that seeks to recover damages or 
obtain other relief in connection with any of such transactions.

          (m)  The Company has not taken and will not take, directly or 
indirectly, any action designed to cause or result in, or which constitutes 
or which might reasonably be expected to constitute, the stabilization or 
manipulation of the price of the shares of Common Stock to facilitate the 
sale or resale of the Shares.

          (n)  The consolidated financial statements, including the notes 
thereto, and supporting schedules included in the Registration Statement and 
as will be set forth in the Prospectus present fairly the financial 
condition, results of operations, stockholders' equity and cash flows and 
other information purported to be shown therein of the Company and its 
subsidiaries and Associated and its subsidiary, respectively, at the dates 
and for the periods indicated; and the supporting schedules included in the 
Registration Statement present fairly the information required to be stated 
therein.  Such consolidated financial statements have been prepared in 
accordance with generally accepted accounting principles consistently applied 
throughout the periods involved, and are in accordance with the books and 
records of the Company and its subsidiaries and Associated and its 
subsidiary, respectively, in all material respects.  No other financial 
statements are required by Form S-2 or otherwise to be included in the 
Registration Statement or the Prospectus.  The historical financial data set 
forth in the Registration Statement and as will be set forth in the 
Prospectus under the captions "Summary Consolidated Financial and Operating 
Data," "Capitalization," "Selected Consolidated Financial Data" and 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations" fairly present, on the basis stated in the Registration Statement 
and as will be stated in the Prospectus, the information set forth therein 
and have been compiled on a basis consistent with that of the audited 
financial statements included in the Registration Statement and as will be 
set forth in the Prospectus.  All other financial information and statistical 
data set forth in the Registration Statement and as will be set forth in the 
Prospectus have been prepared on an accounting basis consistent with the 
financial statements included in the Registration Statement and as will be 
included in the Prospectus. The pro forma and "as adjusted" financial 
information included in the Registration Statement and as will be included in 
the Prospectus that gives effect to the issuance of the Shares, the 
application of the net proceeds therefrom and the other transactions and 
events specified therein has been properly compiled on the basis of the 
assumptions set forth with respect thereto.  The pro forma adjustments to the 
historical figures have been properly applied to such figures and such pro 
forma financial information complies in all material respects with the 
applicable accounting requirements of the Commission.

          (o)  Each of the Company and each of its subsidiaries has good and 
marketable title to all the properties and assets reflected as owned in the 
financial statements (or elsewhere) in the Registration Statement and as will 
be set forth in the Prospectus, subject to no lien, mortgage, pledge, charge 
or encumbrance of any kind except (i) those, if any, reflected in the 
financial statements, or (ii) those which are not material in amount and do 
not adversely affect the use made and proposed to be made of such property by 
the Company and its subsidiaries.  Each of the Company and its subsidiaries 
holds its leased properties under valid, subsisting and enforceable leases, 
with such exceptions as are not, individually or in the aggregate, material 
and do not individually or in the aggregate,

                                          6
<PAGE>

interfere with the use made or proposed to be made of such properties by the 
Company or any of its subsidiaries.  Except as disclosed in the Registration 
Statement and as will be disclosed in the Prospectus, the Company and each of 
its subsidiaries own or lease all such properties as are necessary to its 
operations as now conducted or as proposed to be conducted.

          (p)  The Company is not, and upon consummation of the transactions 
contemplated hereby will not be, subject to registration as an "investment 
company" or an entity "controlled by" an "investment company" within the 
meaning of Investment Company Act of 1940 and the rules and regulations 
promulgated thereunder.

          (q)  The Company and each of its subsidiaries have (i) filed all 
federal, state and local and foreign tax returns which are required to be 
filed through the date hereof, and all such tax returns are true, complete 
and accurate in all material respects, or (ii) received valid extensions 
thereof and have paid all taxes shown on such returns and all assessments 
received by them except where, in the case of state and local and foreign tax 
returns, the failure to file, extend the due date of or pay the same, in the 
aggregate, could not reasonably be expected to have a material adverse effect 
on the business, prospects, properties, assets, earnings, operations, 
condition (financial or other) or results of operations of the Company; the 
Company has no knowledge of any tax deficiency which has been or might be 
asserted against the Company or any of its subsidiaries which could 
materially and adversely affect the business or properties of the Company and 
its subsidiaries taken as a whole.  To the Company's best knowledge, all tax 
liabilities are adequately provided for on the consolidated books of the 
Company.

          (r)  The Company and each of its subsidiaries own or possess 
adequate licenses or other rights to use all patents, trademarks, service 
marks, trade names, copyrights, technology and know-how necessary to conduct 
the business now or proposed to be conducted by the Company and each of its 
subsidiaries as described in the Registration Statement and as will be 
described in the Prospectus, and, except as disclosed in the Registration 
Statement and as will be disclosed in the Prospectus, neither the Company nor 
any of its subsidiaries has received any notice of infringement of or 
conflict with (or knows of such infringement or conflict with) rights of 
others with respect to any patents, trademarks, service marks, trade names, 
copyrights or know-how.  To the best knowledge of the Company, the Company 
and each of its subsidiaries do not in the conduct of their business as now 
conducted or proposed to be conducted, infringe or conflict with any such 
rights of any third party.

          (s)  There are no contracts, indentures, mortgages, loan 
agreements, notes, leases or other agreements or instruments or other 
documents (collectively, "DOCUMENTS") required to be described or referred to 
in, or filed with, the Registration Statement and, in respect of the 
representation made at the Closing Date and the Additional Closing Date, the 
Prospectus, other than those described or referred to therein or filed as 
exhibits thereto.  All such descriptions are accurate in all material respect 
and present fairly the information described therein.  All such Documents to 
which the Company or any of its subsidiaries is a party have been duly 
authorized, executed and delivered by the Company or its subsidiaries, as the 
case may be, constitute valid and binding agreements of the Company or its 
subsidiaries, as the case may be, and are enforceable against the Company or 
its subsidiaries, as the case may be, in accordance with the terms thereof, 
except as the enforceability thereof

                                          7
<PAGE>

may be limited by bankruptcy, insolvency, fraudulent conveyance, 
reorganization, moratorium or other similar laws affecting the enforcement of 
creditors' rights generally and by general equitable principles.

          (t)  There are no outstanding loans, advances (except normal 
advances for business expenses in the ordinary course of business) or 
guarantees of indebtedness by the Company or any of its subsidiaries to or 
for the benefit of any of the officers or directors of the Company or any of 
its subsidiaries or any of the members of the families of any of them, except 
as adequately disclosed in the Registration Statement and as will be 
disclosed in the Prospectus.  All such descriptions are accurate in all 
material respects and present fairly the information required to be described 
in the Registration Statement and as will be described in the Prospectus.

          (u)  There are no rights of return or other agreements between the 
Company and any customer of the Company which would cause any sales reflected 
in the Company's consolidated financial statements for the year ended 
December 31, 1996 included in the Registration Statement and to be included 
in the Prospectus to fail to qualify as sales in accordance with generally 
accepted accounting principles or the Company's revenue recognition policy as 
reflected in the audited financial statements included in the Registration 
Statement and to be included in the Prospectus.

          (v)  Each of the Company and its subsidiaries maintains a system of 
internal accounting controls sufficient to provide reasonable assurances that 
(i) transactions are executed in accordance with management's general or 
specific authorizations; (ii) transactions are recorded as necessary to 
permit preparation of financial statements in conformity with generally 
accepted accounting principles and to maintain accountability for assets; 
(iii) access to assets is permitted only in accordance with management's 
general or specific authorization; and (iv) the recorded accountability for 
assets is compared with existing assets at reasonable intervals and 
appropriate action is taken with respect to any differences.

          (w)  Neither the Company nor any of its subsidiaries is in 
violation or breach of, or in default (nor has any event occurred which with 
notice, or lapse of time, or both, would constitute a default) of any 
contract, agreement, indenture, loan or other agreement, instrument, 
mortgage, note, permit, lease, license, arrangement or understanding to which 
the Company or any of its subsidiaries is a party or by which the Company, 
any of its subsidiaries or any of their respective properties may be bound 
where such default, either individually or together with all such other 
defaults, could reasonably be expected to have a material adverse effect on 
the business, prospects, properties, assets, earnings, operations, condition 
(financial or other) or results of operations of the Company or on the 
ability of the Company to perform its obligations hereunder.  Each such 
contract, agreement, indenture, loan or other agreement, instrument, 
mortgage, note, permit, lease, license, arrangement and understanding is in 
full force and effect and is the legal, valid and binding obligation of the 
Company or its subsidiaries, as the case may be, and, to the Company's 
knowledge, the other parties thereto and is enforceable against the Company 
or its subsidiaries, as the case may be, and, to the Company's knowledge, 
against the other parties thereto in accordance with its terms.  Neither the 
Company nor or any of its subsidiaries is a party to or bound by any 
contract, agreement, indenture, loan or other agreement, instrument, 
mortgage, note, permit, lease, license, arrangement or understanding, or 
subject to any charter or other restriction,

                                          8
<PAGE>

which has had or is reasonably expected in the future to have a material 
adverse effect on the business, prospects, properties, assets, earnings, 
operations, condition (financial or other) or results of operations of the 
Company.  Neither the Company nor any of its subsidiaries is in violation or 
breach of, or in default with respect to, any term of its respective 
certificate of incorporation or bylaws and neither the Company nor any of its 
subsidiaries is in default (nor has an event occurred which with notice, 
lapse of time or both would constitute a default) in the performance of any 
obligation, agreement or condition contained in any loan agreement of the 
Company or any such subsidiary where such default could have a material 
adverse effect on the Company and its subsidiaries taken as a whole. Neither 
the Company nor any of its subsidiaries is in violation of, or in default 
with respect to, any law, rule, regulation, order, judgment or decree, except 
such as are described in the Registration Statement and as will be described 
in the Prospectus or such as, individually or in the aggregate, could not 
reasonably be expected to have a material adverse effect upon the business, 
prospectus, properties, assets, earnings, operations, condition (financial or 
other) or results of operations of the Company.

          (x)  The Company has obtained from each of the Company's officers 
and directors, the Selling Stockholders and the holders of capital stock of 
the Company named on Schedule IV attached hereto a written agreement (a 
"LOCK-UP AGREEMENT"), in a form or forms approved by the Representatives and 
their counsel, that for a period of 90 days from the date of the Prospectus 
such person will not (i) directly or indirectly, offer to sell, contract to

options or warrants to purchase any shares of Common Stock or any securities 
convertible into or exchangeable for shares of Common Stock (collectively, 
"SECURITIES"), now owned or hereafter acquired by such person or with respect 
to which such person has or hereafter acquires the power of disposition, 
otherwise than (A) as a bona fide gift or gifts, provided the donee or donees 
thereof agree to be bound in writing by the terms of the Lock-Up Agreement, 
(B) as a distribution to limited partners or stockholders of such person 
provided that the distributees thereof agree in writing to be bound by the 
terms of the Lock-Up Agreement, or (C) with the prior written consent of the 
Representatives, or (ii) make any demand for or exercise any right with 
respect to the registration of any Common Stock or other securities of the 
Company.

          (y)  Except as described in the Registration Statement and as will

Company and any of its subsidiaries exists or, to the best knowledge of the 
Company, is threatened and the Company is not aware of any labor disturbance 
by the employees of any of its significant manufacturers, suppliers, 
customers or contractors that could reasonably be expected to have a material 
adverse effect on the business, prospects, properties, assets, earnings, 
operations, condition (financial or other) or results of operations of the 
Company.

          (z)  Except as described in the Registration Statement and as will 
be described in the Prospectus, (i) the Company is not a party to or bound by 
any stockholders' agreements or voting trusts with respect to any securities 
of the Company and (ii) there are no contracts, agreements or understandings 
between the Company or any of its subsidiaries and any person or entity 
granting such person or entity the right to require the Company to file a 
registration statement under the Act with respect to any securities of the 
Company

                                          9

owned or to be owned by such person or entity or to require the Company to 
include such securities in the securities registered pursuant to the 
Registration Statement.

          (aa) To the best knowledge of the Company, except as disclosed in 
the Registration Statement and as will be described in the Prospectus,

other approvals required under applicable federal and state occupational 
safety and health and environmental laws and regulations to conduct their 
respective businesses.  The Company and each of its subsidiaries is in 
compliance with all terms and conditions of any such permits, licenses or 
approvals, except any such violation of law or regulation, failure to receive 
required permits, licenses or other approvals or failure to comply with the 
terms and conditions of such permits, licenses or approvals which could not, 
individually or together with all such other violations or failures, have a 
material adverse effect on the Company or its business, prospects, 
properties, assets, earnings, operations, condition (financial or other) or 
results of operations.

          (bb) The Company has not incurred any liability for any finder's 
fees or similar payments in connection with the transactions herein 
contemplated.

          (cc) The Company, either directly or through one or more of its

on behalf of such Selling Stockholder, to determine the purchase price to be 
paid by the Underwriters to such Selling Stockholder as provided in Section 
3(a) hereof, to authorize the delivery of the Shares and/or Warrants to be

the Selling Agreements by for on behalf of such Selling Stockholder and the 
consummation of the transactions contemplated hereby and thereby will not (i) 
conflict with or result in the breach of any of the terms and provisions of,

Agreements and the consummation of the transactions contemplated hereby and 
thereby, including the sale, assignment, transfer and delivery of the Shares 
and/or Warrants to be sold, assigned, transferred and delivered by such

Stockholder expressly for use therein did not contain an untrue statement of 
a material fact and did not omit to state any material fact required to be 
stated therein or necessary in order to make the statements therein not 
misleading.

any amendment to the Registration Statement becomes effective, when the 
Prospectus is first used to confirm sales of the Shares, when any amendment 
of or supplement to the Prospectus is filed with the Commission, at the 
Closing Date and, if applicable, the Additional Closing Date, the 
Registration Statement and the Prospectus and any amendments thereof 0and

                                          12
<PAGE>

supplements thereto will not contain an untrue statement of a material 
fact and will not omit to state any material fact required to be stated 
therein or necessary in order to make the statements therein not misleading.  
When any related preliminary prospectus was first filed with the Commission 
(whether filed as part of the registration statement for the registration of 
the Shares and Warrants or any amendment thereto or pursuant to Rule 424(a) 
of the Regulations) and when any amendment thereof or supplement thereto was 
first filed with the Commission, such preliminary prospectus and any 
amendments thereof and supplements thereto did not contain an untrue 
statement of a material fact and did not omit to sate any material fact 
required to be stated therein or necessary in order to make the statements 
therein not misleading.

          (i)  In order to document the Underwriters' compliance with the 
reporting and withholding provisions of the Tax Equity and Fiscal 
Responsibility Act of 1982 with respect to the transactions herein 
contemplated, each of the Selling Stockholders agrees to deliver to the 
Representatives prior to or at the Closing Date and, if applicable, the 
Additional Closing Date, a properly completed and executed United States 
Treasury Department Form W-9 (or other applicable form or statement specified 
by Treasury Department regulations in lieu thereof).

          (j)  Each of the Selling Stockholders specifically agrees that the 
Shares represented by the certificates or Warrants held in custody for such 
Selling Stockholder under the Selling Agreements are subject to the interests 
of the Underwriters hereunder and that the arrangements made by such Selling 
Stockholder for such custody and the appointment by such Selling Stockholder 
of the Attorney-in-Fact by the Power of Attorney are to that extent 
irrevocable.  Each of the Selling Stockholders specifically agrees that the 
obligations of the Selling Stockholders hereunder shall not be terminated by 
operation of law, whether by the death or incapacity of any executor or 
trustee or the termination of such estate or trust, or in the case of a 
partnership or corporation, by the dissolution of such partnership or 
corporation, or by the occurrence of any other event.  If any individual 
Selling Stockholder or any such executor or trustee should die or become 
incapacitated, or if any such estate or trust should be terminated, or if any 
such partnership or corporation should be dissolved, or if any other such 
event should occur before the delivery of the Shares and/or Warrants 
hereunder, certificates representing the Shares and/or Warrants shall be 
delivered by or on behalf of such Selling Stockholder in accordance with the 
terms and conditions of this Agreement and the Selling Agreements, and 
actions taken by the Attorneys-in-Fact pursuant to the Powers of Attorney 
shall be as valid as if such death, incapacity, termination, dissolution or 
other event had not occurred, regardless of whether or not the Custodian, the 
Attorneys-in-Fact, or any of them, shall have received notice of such death, 
incapacity, termination, dissolution or other event.

          (k)  Such Selling Stockholder confirms that the sale of such 
Selling Stockholder's Shares and/or Warrants pursuant to this Agreement is 
not prompted by any information concerning  the Company which is not set 
forth in the Prospectus.

     3.   PURCHASE, SALE AND DELIVERY OF THE SHARES AND WARRANTS.

          (a)  On the basis of the representations, warranties, covenants and 
agreements herein contained, but subject to the terms and conditions herein 
set forth, the

                                          13
<PAGE>

Company agrees to sell to the several Underwriters 2,000,000 of the Firm 
Shares and each of the Selling Stockholders selling Firm Shares agrees, 
severally and not jointly, to sell to the several Underwriters the number of 
Firm Shares set forth opposite the names of such Selling Stockholders on 
Schedule II attached hereto, and each Underwriter, severally and not jointly, 
agrees to purchase from the Company and each of the Selling Stockholders, at 
the price per share of $_____________, the number of Firm Shares (to be 
adjusted by the Representatives to avoid fractional shares) determined by 
multiplying the aggregate number of Firm Shares to be sold by the Company and 
each of such Selling Stockholders, as set forth opposite their respective 
names in Schedule II hereto, by a fraction, the numerator of which is the 
aggregate number of Firm Shares to be purchased by such Underwriter as set 
forth opposite the name of such Underwriter in Schedule I hereto and the 
denominator of which is the aggregate number of Firm Shares to be purchased 
by all the Underwriters hereunder, plus any additional number of Shares which 
such Underwriter may become obligated to purchase pursuant to the provisions 
of Section 10 hereof.    Each of the Selling Stockholders selling Firm 
Warrants agrees, severally and not jointly, to sell Firm Warrants to purchase 
the number of shares set forth opposite the name of such Selling Stockholder 
in Schedule II hereto, to the several Underwriters, and each Underwriter 
agrees, severally and not jointly, to purchase from such Selling Stockholders 
that portion of the Firm Warrants (to be adjusted by the Representatives to 
avoid fractional shares) which represents the same proportion as the number 
of Firm Shares set forth opposite the name of each Underwriter in Schedule I 
hereto bears to the total number of Firm Shares, at the purchase price per 
Share issuable upon exercise of the portion of the Warrants purchased equal 
to (i) $___________, minus (ii) the exercise price of the respective Firm 
Warrants so purchased, plus any additional number of Warrants which such 
Underwriter may become obligated to purchase pursuant to Section 10 hereof. 
Each of the Underwriters, severally and not jointly, agrees to exercise the 
portion of the Firm Warrants purchased by such Underwriter by tendering such 
Firm Warrant portion to the Company together with the payment of the exercise 
price thereof, and the Company agrees, upon such exercise, to issue and sell 
to such Underwriter the number of Firm Shares issuable upon exercise of the 
portion of the Firm Warrants so exercised.

     In the event and to the extent that the Underwriters shall exercise the 
election to purchase Additional Shares and Additional Warrants as provided in 
paragraph 3(c) below, the Selling Stockholders, severally and not jointly, 
agree to sell to each of the Underwriters, and each of the Underwriters 
agrees, severally and not jointly, to purchase from the Selling Stockholders, 
at the purchase price per share set forth above in this Section 3(a), that 
number of Additional Shares and Additional Warrants as determined in 
accordance with paragraph 3(c) below, plus any additional number of Shares or 
Warrants which such Underwriter may become obligated to purchase pursuant to 
the provisions of Section 10 hereof.

          (b)  Delivery of certificates, and payment of the purchase price, 
for the Firm Shares (including Shares issued upon exercise of Warrants) shall 
be made at the offices of Haynes and Boone, LLP, 901 Main Street, Suite 3100, 
Dallas, Texas, or such other location as may be mutually acceptable to the 
Representatives, the Attorneys-in-Fact and the Company.  Such delivery and 
payment shall be made at 10:00 a.m., New York time, on the third or fourth 
business day (as permitted under Rule 15c6-1 under the Exchange Act) (unless 
postponed in accordance with the provisions of Section 10 hereof) following 
the date of the effectiveness of the Registration Statement (or, if the 
Company has elected to rely upon

                                          14
<PAGE>

Rule 430A of the Regulations, the third or fourth business day (as permitted 
under Rule 15c6-1 under the Exchange Act) after the determination of the 
initial public offering price of the Shares), or such other time not later 
than ten business days after such date as shall be agreed upon by the 
Representatives and the Company (such time and date of payment and delivery 
being herein called the "CLOSING DATE").  Payment shall be made to the 
Company by certified or official bank check or checks drawn in federal funds 
or similar same day funds payable to the order of the Company, against 
delivery to the Representatives for the respective accounts of the 
Underwriters of certificates for the Shares to be purchased by them. 
Certificates for the Shares (including Shares issued upon exercise of 
Warrants) shall be registered in such name or names and in such authorized 
denominations as the Representatives may request in writing at least two full 
business days prior to the Closing Date.  The Company and the Selling 
Stockholders will permit the Representatives to examine and package such 
certificates for delivery at least one full business day prior to the Closing 
Date.

          (c)  In addition, the Selling Stockholders, as and to the extent 
indicated on Schedule II attached hereto, hereby grant to the several 
Underwriters an option to purchase up to 600,000 Additional Shares (including 
the purchase and exercise of the Additional Warrants) at the same purchase 
price (and, with respect to the Additional Warrants, upon the same terms) to 
be paid by the several Underwriters to the Company and the Selling 
Stockholders for the Firm Shares and Firm Warrants as set forth in Section 
3(a), for the sole purpose of covering over-allotments in the sale of Firm 
Shares by the several Underwriters.  This option may be exercised, in whole 
or in part, at any time on or before the thirtieth (30th) calendar day 
following the date of the Prospectus, by written notice by the 
Representatives to the Custodian.  Such notice shall set forth the aggregate 
number of Additional Shares (including the purchase and exercise of the 
Additional Warrants) as to which the option is being exercised and the date 
and time, as reasonably determined by the Representatives, when the 
certificates relating to the Additional Shares (including Shares issued upon 
exercise of the Additional Warrants) are to be delivered (such date and time 
being herein sometimes referred to as the "ADDITIONAL CLOSING DATE"); 
provided, however, that the Additional Closing Date shall not be earlier than 
the Closing Date or earlier than the second (2nd) full business day after the 
date on which the option shall have been exercised nor later than the eighth 
(8th) full business day after the date on which the option shall have been 
exercised, unless such time and date are postponed in accordance with the 
provisions of Section 10 hereof.  Certificates for the Additional Shares 
(including Shares issued upon exercise of the Additional Warrants) shall be 
registered in such name or names and in such authorized denominations as the 
Representatives may request in writing at least two full business days prior 
to the Additional Closing Date.  The Company will permit the Representatives 
to examine and package such certificates for delivery at least one full 
business day prior to the Additional Closing Date.

          If the option is exercised in full, the number of Additional Shares 
and/or Additional Warrants to be sold by each of the Selling Stockholders (as 
adjusted by the Representatives to eliminate fractions), as the case may be, 
shall be as is set forth opposite their respective names on Schedule II 
attached hereto. In the event that the option is exercised in part, the 
number of Additional Shares and/or Additional Warrants to be sold by each 
Selling Stockholder shall be determined by multiplying the number of 
Additional Shares and/or Additional Warrants to be purchased from all Selling 
Stockholders by the several

                                          15
<PAGE>

Underwriters by a fraction the numerator of which is the number of Firm 
Shares and/or Firm Warrants sold by such Selling Stockholder and the 
denominator of which is the maximum number of Firm Shares and Firm Warrants 
to be sold by all of the Selling Stockholders hereunder.  The number of 
Additional Shares and/or Additional Warrants to be purchased from each 
Selling Stockholder by each Underwriter (as adjusted by the Representatives 
to eliminate fractions) shall be determined by multiplying the number of 
Additional Shares and/or Additional Warrants to be sold by such Selling 
Stockholder by a fraction, the numerator of which is the number of Firm 
Shares and Firm Warrants purchased by such Underwriter and the dominator of 
which is the maximum number of Firm Shares and Firm Warrants which all of the 
Underwriters are entitled to purchase hereunder.  The number of Additional 
Shares and/or Additional Warrants to be purchased by each Underwriter if the 
option is exercised in full is set forth opposite the name of such 
Underwriter on Schedule I attached hereto.

          Payment for the Additional Shares and/or Additional Warrants shall 
be made by certified or official bank check, in New York Clearing House funds 
or similar next day funds, payable to the order of the Custodian at the 
offices of Haynes and Boone, LLP, 901 Main Street, Suite 3100, Dallas, Texas, 
or such other location as may be mutually acceptable, upon delivery of the 
certificates for the Additional Shares to the Representatives for the 
respective accounts of the Underwriters.

     4.   OFFERING.  It is understood that after the Registration Statement 
becomes effective under the Act the several Underwriters propose to offer the 
Shares for sale to the public upon the terms set forth in the Prospectus.

     5.   COVENANTS OF THE COMPANY AND THE SELLING STOCKHOLDERS.

          (a)  The Company covenants and agrees with the several Underwriters 
that:

               (i)  If the Registration Statement has not yet been declared
     effective, the Company will use its best efforts to cause the Registration
     Statement and any amendments thereto to become effective as promptly as
     possible, and if Rule 430A is used or the filing of the Prospectus is
     otherwise required under Rule 424(b) or Rule 434, the Company will file the
     Prospectus (properly completed if Rule 430A has been used) pursuant to Rule
     424(b) or Rule 434 within the prescribed time period and will provide
     evidence satisfactory to the Representatives of such timely filing.  If the
     Company elects to rely on Rule 434, the Company will prepare and file a 
     term sheet that complies with the requirements of Rule 434.

               The Company will notify the Representatives immediately (and, if
     requested by the Representatives, will confirm such notice in writing) (A)
     when the Registration Statement and any amendments thereto become 
     effective, (B) of any request by the Commission for any amendment of or 
     supplement to the Registration Statement or the Prospectus or for any 
     additional information, (C) of the mailing or the delivery to the 
     Commission for filing of any amendment of or supplement to the 
     Registration Statement or the Prospectus, (D) of the issuance by the 
     Commission of any Stop Order suspending the effectiveness of the 
     Registration Statement or any post-effective amendment thereto or of the 
     initiation, or the threatening, of any


                                          16
<PAGE>

     proceedings therefor, (E) of the receipt of any comments from the 
     Commission, and (F) of the receipt by the Company of any notification with 
     respect to the suspension of the qualification of the Shares for sale in 
     any jurisdiction or the initiation or threatening of any proceeding for 
     that purpose.  If the Commission shall propose or enter a Stop Order at 
     any time, the Company will make every reasonable effort to prevent the 
     issuance of any such Stop Order and, if issued, to obtain the lifting of 
     such Stop Order as soon as possible.  The Company will not file any 
     amendment to the Registration Statement or any amendment of or supplement 
     to the Prospectus (including the prospectus required to be filed pursuant 
     to Rule 424(b)or Rule 434) that differs from the prospectus on file at the 
     time of the effectiveness of the Registration Statement before or after 
     the effective date of the Registration Statement or file any document under
     the Exchange Act if such document would be deemed to be incorporated by 
     reference into the Prospectus to which the Representatives shall reasonably
     object in writing after being timely furnished in advance a copy thereof.

               (ii) If, at any time when a prospectus relating to the Shares is
     required to be delivered under the Act, any event shall have occurred as a
     result of which the Prospectus as then amended or supplemented would, in 
     the judgment of the Underwriters or the Company, include an untrue 
     statement of a material fact or omits to state any material fact required 
     to be stated therein or necessary to make the statements therein, in the 
     light of the circumstances under which they were made, not misleading, or 
     if it shall be necessary at any time to amend or supplement the Prospectus
     or Registration Statement to comply with the Act or the Regulations, the 
     Company will notify the Representatives promptly and prepare and file with
     the Commission an appropriate post-effective amendment or supplement (in 
     form and substance satisfactory to the Representatives) which will correct
     such statement or omission and will use its best efforts to have any such 
     post-effective amendment to the Registration Statement declared effective 
     as soon as possible.

               (iii)     The Company will promptly deliver to the 
     Representatives three signed copies of the Registration Statement, 
     including exhibits and all documents incorporated by reference therein and
     all amendments thereto, and the Company will promptly deliver to each of 
     the  several Underwriters such number of copies of any preliminary 
     prospectus, the Prospectus, the Registration Statement, and all amendments 
     of and  supplements to such documents, if any, and all documents 
     incorporated by  reference in the Registration Statement and Prospectus or 
     any amendment thereof or supplement thereto, without exhibits, as the 
     Representatives may reasonably request.

               (iv) The Company will endeavor in good faith, in cooperation with
     the Representatives, at or prior to the time of effectiveness of the
     Registration Statement, to qualify the Shares for offering and sale under 
     the securities laws relating to the offering or sale of the Shares of such
     jurisdictions as the Representatives may designate and to maintain such
     qualification in effect for so long as required for the distribution 
     thereof.

               (v)  The Company will make generally available (within the 
     meaning of Section 11(a) of the Act) to its securityholders and to the
     Representatives as soon


                                          17
<PAGE>

     as practicable, but not later than 45 days after the end of its fiscal
     quarter in which the first anniversary date of the effective date of the
     Registration Statement occurs, an earnings statement (in form complying 
     with the provisions of Rule 158 of the Regulations) covering a period of 
     at least twelve consecutive months beginning after the effective date of 
     the Registration Statement.

               (vi) During the period of 90 days from the date of the 
     Prospectus, the Company will not, without the Representatives' prior 
     written consent, either directly or indirectly, offer to sell, contract to
     sell or otherwise sell, dispose of, loan, pledge or grant any rights with 
     respect to any shares of Common Stock (or any securities convertible into,
     exercisable for or exchangeable for Common Stock), other than the 
     Company's sale of Shares hereunder and the Company's issuance of Common 
     Stock upon the exercise of presently outstanding stock options.

               (vii)     The Company has obtained and delivered to the
     Representatives, no later than the close of business on the date hereof, a
     Lock-Up Agreement from each of its directors and officers and each holder 
     of capital stock of the Company listed on Schedule III attached hereto.

               (viii)    During a period of three years from the effective date 
     of the Registration Statement, the Company will furnish to the 
     Representatives copies of (A) all reports to its stockholders; and (B) all
     reports, financial statements and proxy or information statements filed by
     the Company with the Commission or any exchange upon which the Common 
    Stock is listed or approved for quotation.

               (ix) The Company will apply the proceeds from the sale of the
     Shares by the Company as will be set forth under "Use of Proceeds" in the
     Prospectus.

          (b)  Each Selling Stockholder hereby covenants and agrees with the 
several Underwriters, during the period commencing on the date hereof and 
ending 90 days after the date of the Prospectus, not to make a Disposition of 
any Securities, now owned or hereafter acquired by such Selling Stockholder 
or with respect to which such Selling Stockholder has or hereafter acquires 
the power of disposition, otherwise than (i) as a bona fide gift or gifts, 
provided the donee or donees thereof agree to be bound in writing by the 
terms of this Section 5(b), (ii) as a distribution to limited partners or 
stockholders of such Selling Stockholder provided that the distributees 
thereof agree in writing to be bound by the terms of this Section 5(b), or 
(iii) with the prior written consent of the Representatives.  The foregoing 
restriction is expressly agreed to preclude such Selling Stockholder from 
engaging in any hedging or other transaction which is designed to or 
reasonably expected to lead to or result in a Disposition of Securities 
during the 90 days after the date of the Prospectus even if such shares would 
be disposed of by someone other than such Selling Stockholder.  Such 
prohibited hedging or other transactions would include, without limitation, 
any short sale (whether or not against the box) or any purchase, sale or 
grant of any right (including, without limitation, any put or call option) 
with respect to any Securities or with respect to any security (other than a 
broad-based market basket or index) that relates to or derives any 
significant part of its value from the Common Stock.  Each Selling 
Stockholder further agrees not to make any demand for or exercise any right 
with respect to the registration of any Common Stock or other securities of 
the Company.  Notwithstanding the foregoing, this Section 5(b) does not

                                          18
<PAGE>

prohibit the sale of the Shares by such Selling Stockholder to the 
Underwriters pursuant to this Agreement.  Such Selling Stockholder confirms 
that this Section 5(b) is irrevocable and shall be binding upon such Selling 
Stockholder, and such Selling Stockholder agrees and consents to the entry of 
stop transfer instructions with the Company's transfer agent against the 
transfer of the Shares of Common Stock held by such Selling Stockholder 
except in compliance with this Section 5(b).

     6.   PAYMENT OF EXPENSES.  Whether or not the transactions contemplated 
in this Agreement are consummated or this Agreement is terminated, the 
Company agrees to pay all costs and expenses incident to the performance of 
the obligations of the Company and the Selling Stockholders hereunder, 
including those in connection with (i) preparing, printing, duplicating, 
filing and distributing the Registration Statement, as originally filed and 
all amendments thereof (including all exhibits thereto), any preliminary 
prospectus, the Prospectus and any amendments thereof or supplements thereto 
(including, without limitation, fees and expenses of the Company's 
accountants and counsel), the underwriting documents (including this 
Agreement, the Agreement Among Underwriters and the Selling Agreements) and 
all other documents related to the public offering of the Shares (including 
those supplied to the Underwriters in quantities as hereinabove stated), (ii) 
the issuance, transfer and delivery of the Shares to the Underwriters, 
including any transfer or other taxes payable thereon, (iii) the 
qualification of the Shares under state or foreign securities or Blue Sky 
laws, including the costs of printing and mailing a preliminary and final 
"Blue Sky Survey" and the fees of counsel for the Underwriters and such 
counsel's disbursements in relation thereto, (iv) the inclusion of the Shares 
to be sold by the Company on the Nasdaq National Market, (v) the review of 
the terms of the public offering of the Shares by the National Association of 
Securities Dealers, Inc. (the "NASD") (including, without limitation, fees 
and expenses to Underwriters' counsel in relation thereto), and (vi) the 
reasonable fees and expenses of one counsel acting on behalf of the Selling 
Stockholders.  Notwithstanding the foregoing, each Selling Stockholder will 
pay or cause to be paid all costs and expenses incident to the performance of 
such Selling Stockholder's obligations hereunder which are not otherwise 
specifically provided for in this Section 6, including the Underwriters' 
discount and commissions applicable to such Selling Stockholder's Shares.

     7.   CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The obligations of the 
several Underwriters to purchase and pay for the Firm Shares and, if 
applicable, the Additional Shares shall be subject to the accuracy of the 
representations and warranties of the Company and the Selling Stockholders 
herein contained, as of the date hereof and as of the Closing Date (or in the 
case of the Additional Shares as of the Additional Closing Date), to the 
absence from any certificates, opinions, written statements or letters 
furnished to the Representatives or to Haynes and Boone, LLP ("UNDERWRITERS' 
COUNSEL") pursuant to this Section 7 of any qualification or limitation not 
previously approved in writing by the Representatives, to the performance by 
the Company and the Selling Stockholders of their respective obligations 
hereunder, and to the following additional conditions:

          (a)  The Registration Statement shall have become effective not 
later than 5:30 P.M., New York time, on the date of this Agreement, or at 
such later time and date as shall have been consented to in writing by the 
Representatives; if the Company shall have elected to rely upon Rule 430A or 
Rule 434 of the Regulations, the Prospectus shall have been filed with the 
Commission in a timely fashion in accordance with Section 5(a) hereof; and,

                                          19
<PAGE>

at or prior to the Closing Date no Stop Order suspending the effectiveness of 
the Registration Statement or any post-effective amendment thereof shall have 
been issued and no proceedings therefor shall have been initiated or 
threatened by the Commission.

          (b)  At the Closing Date and, if applicable, the Additional Closing 
Date, the Representatives shall have received the opinion of Weil, Gotshal & 
Manges LLP, counsel for the Company, dated the Closing Date or the Additional 
Closing Date, as the case may be, addressed to the Underwriters and in form 
and substance satisfactory to Underwriters' Counsel, to the effect that:

               (i)  Each of the Company and its subsidiaries has been duly
     organized and is validly existing as a corporation in good standing under 
     the laws of its jurisdiction of incorporation.  Each of the Company and its
     subsidiaries is duly qualified and in good standing as a foreign 
     corporation in each jurisdiction in which the character or location of its
     properties (owned, leased or licensed) or the nature or conduct of its 
     business makes such qualification necessary, except for those failures to 
     be so qualified or in good standing which will not in the aggregate have 
     a material adverse effect on the Company and its subsidiaries taken as a 
     whole.  Each of the Company and its subsidiaries has all requisite 
     corporate authority to own, lease and license its respective properties 
     and conduct its business as now being conducted and as described in the 
     Registration Statement and the Prospectus.  All of the issued and 
     outstanding capital stock of USSC has been duly and validly issued and is 
     fully paid and non-assessable and free of preemptive rights and, except as
     disclosed in the Registration Statement and the Prospectus, is owned 
     directly by the Company, free and clear of any lien, encumbrance, claim, 
     security interest, restriction on transfer, stockholders' agreement, 
     voting trust or other defect of title whatsoever.

               (ii) The Company has authorized capital stock as set forth in the
     Registration Statement and the Prospectus.  All of the outstanding shares 
     of Common Stock are duly and validly authorized and issued, are fully paid 
     and nonassessable and were not issued in violation of or subject to any
     preemptive rights.  The Shares to be delivered by the Company on the 
     Closing Date have been duly and validly authorized and, when delivered in 
     accordance with this Agreement, will be duly and validly issued, fully 
     paid and nonassessable and will not have been issued in violation of or 
     subject to any preemptive rights.  Each of the Underwriters will receive 
     good, valid and marketable title to the Firm Shares being sold by the 
     Company hereunder, free and clear of all liens, encumbrances, claims, 
     security interests, restrictions on transfer, stockholders' agreements, 
     warrant agreements, voting trusts and other defects of title whatsoever.  
     The Common Stock, the Firm Shares and the Additional Shares conform to 
     the descriptions thereof contained in the Registration Statement and the 
     Prospectus.

               (iii)     The Warrants have been duly and validly authorized and
     issued by the Company and, prior to their exercise, constituted validly
     issued and outstanding warrants of the Company, enforceable in accordance
     with their terms.  The Warrants conform in all material respects to the
     description thereof contained in the Prospectus and, prior to their 
     exercise, the Shares issuable upon exercise of the Warrants were validly 
     reserved for issuance upon exercise thereof.


                                          20
<PAGE>

               (iv) The assignment instruments by which the Warrants have been
     transferred by certain Selling Stockholders to the Underwriters, assuming 
     the due and valid authorization, execution and delivery thereof to the
     Underwriters by the Selling Stockholders or their Attorney-in-Fact, are
     effective to transfer ownership of the Warrants to the Underwriters, free 
     and clear of all liens, encumbrances, security interests, claims, 
     restrictions on transfer, stockholders' agreements, warrant agreements, 
     voting trusts and other defects of title whatsoever.

               (v)  The Common Stock currently outstanding is included, and the
     Shares to be sold under this Agreement by the Company to the Underwriters 
     are duly authorized for inclusion, on the Nasdaq National Market.

               (vi) This Agreement has been duly and validly authorized, 
     executed and delivered by the Company and USSC and is a valid and binding 
     obligation of the Company and USSC, enforceable against each in accordance
     with its terms, except (i) as the enforceability thereof may be limited by
     bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium 
     or other similar laws affecting the enforcement of creditors' rights 
     generally and by general equitable principles and (ii) to the extent that 
     rights to indemnity hereunder may be limited by federal or state 
     securities laws or the public policy underlying such laws.

               (vii)     To the best of such counsel's knowledge, there is no
     litigation or governmental or other action, suit, proceeding or 
     investigation before any court or before or by any public, regulatory or 
     governmental agency or body pending or threatened against, or involving 
     the properties or business of, the Company or any of its subsidiaries, 
     which, if resolved against the Company or such subsidiary, individually or,
     to the extent involving related claims or issues, in the aggregate, is of 
     a character required to be disclosed in the Registration Statement and the
     Prospectus which has not been properly disclosed therein.

               (viii)    The execution, delivery, and performance of this
     Agreement and the consummation of the transactions contemplated hereby by 
     the Company and USSC do not and will not (A) conflict with or result in a 
     breach of any of the terms and provisions of, or constitute a default (or 
     an event which with notice or lapse of time, or both, would constitute a 
     default) or require consent under, or result in the creation or imposition 
     of any lien, charge or encumbrance upon any property or assets of the 
     Company or any of its subsidiaries pursuant to the terms of any agreement, 
     instrument, franchise, license or permit known to such counsel to which 
     the Company or any of its subsidiaries is a party or by which any of such 
     corporations or their respective properties or assets may be bound or (B) 
     violate or conflict with any provision of the certificate of incorporation 
     or bylaws of the Company or any of its subsidiaries, or, to the best 
     knowledge of such counsel, any judgment, decree, order, statute, rule or 
     regulation of any court or any public, governmental or regulatory agency 
     or body having jurisdiction over the Company or


                                          21
<PAGE>

     any of its subsidiaries or any of their respective properties or assets.  
     No consent, approval, authorization, order, registration, filing, 
     qualification, license or permit of or with any court or any public, 
     governmental or regulatory agency or body having jurisdiction over the 
     Company or any of its subsidiaries or any of their respective properties 
     or assets is required for the execution, delivery and performance of this 
     Agreement and the consummation of the transactions contemplated hereby, 
     except for (1) such as may be required under state securities or Blue Sky 
     laws in connection with the purchase and distribution of the Shares by the 
     Underwriters (as to which such counsel need express no opinion) and (2) 
     such as have been made or obtained under the Act.

               (ix) The Registration Statement and the Prospectus and any
     amendments thereof or supplements thereto (other than the financial
     statements and schedules and other financial and statistical data included 
     or incorporated by reference therein, as to which such counsel need 
     express no opinion) comply as to form in all material respects with the 
     requirements of the Act and the Regulations.  The documents filed under 
     the Exchange Act and incorporated by reference in the Registration 
     Statement and the Prospectus and in any amendment thereof or supplement 
     thereto (other than the financial statements and schedules and other 
     financial and statistical data included or incorporated by reference 
     therein, as to which such counsel need express no opinion) comply as to 
     form in all material respects with the Exchange Act and the rules and 
     regulations of the Commission thereunder.

               (x)  The Registration Statement is effective under the Act, and, 
     to the best knowledge of such counsel, no stop order suspending the
     effectiveness of the Registration Statement or any post-effective amendment
     thereof has been issued and no proceedings therefor have been initiated or
     threatened by the Commission or any state securities or "Blue Sky" 
     authority and all filings required by Rule 424(b) of the Regulations have 
     been made.

               (xi) To the best of such counsel's knowledge, there are no
     contracts, indentures, mortgages, instruments, permits, licenses, loans,
     agreements, notes, leases or other agreements or instruments or other
     documents (collectively, "DOCUMENTS") which are required under the Act to 
     be described or referred to in, or filed with, the Registration Statement 
     and the Prospectus other than those described or referred to therein or 
     filed as exhibits thereto.

               (xii)     The statements under the captions "The Company," 
     "Certain Transactions," "Shares Eligible For Future Sale," "Description of 
     Capital Stock," and "Description of Indebtedness" in the Prospectus, in 
     Items 14 and 15 of Part 11 of the Registration Statement and in Item 3 of 
     the Company's Annual Report on Form 10-K for the fiscal year ended 
     December 31, 1995, insofar as such statements constitute a summary of 
     legal matters, documents or proceedings referred to therein, fairly 
     present, in all material respects, the information called for with respect 
     to such legal matters, documents and proceedings.

               (xiii)    In addition, such opinion shall also contain a 
     statement that such counsel has participated in conferences with officers 
     and representatives of the Company, representatives of the independent 
     public accountants for the Company and the Underwriters at which the 
     contents and the Prospectus and related matters were discussed, and no 
     facts have come to the attention of such counsel which would lead such 
     counsel to believe that either the Registration Statement at the time it 
     became


                                          22
<PAGE>

     effective (including the information deemed to be part of the Registration
     Statement at the time of effectiveness pursuant to Rule 430A(b) or Rule 
     434, if applicable), or any amendment thereof made prior to the Closing 
     Date as of the date of such amendment, contained an untrue statement of a 
     material fact or omitted to state any material fact required to be stated 
     therein or necessary to make the statements therein not misleading or that 
     the Prospectus as of the date thereof (or any amendment thereof or 
     supplement thereto made prior to the Closing Date or the Additional 
     Closing Date, as the case may be, as of the date of such amendment or 
     supplement) and as of the Closing Date and, if applicable, as of the 
     Additional Closing Date, contains or contained an untrue statement of a 
     material fact or omits or omitted to state any material fact required to 
     be stated therein or necessary to make the statements therein, in light of 
     the circumstances under which they were made, not misleading (it being 
     understood that such counsel need express no belief or opinion with 
     respect to the financial statements and schedules and other financial and 
     statistical data included or incorporated by reference therein).

               In rendering such opinion, such counsel may rely (A) as to 
     matters involving the application of laws other than the laws of the 
     United States and jurisdictions in which they are admitted, to the extent 
     such counsel deems proper and to the extent specified in such opinion, if 
     at all, upon an opinion or opinions (in form and substance reasonably 
     satisfactory to Underwriters' Counsel) of other counsel reasonably 
     acceptable to Underwriters' Counsel, familiar with the applicable laws, 
     and (B) as to matters of fact, to the extent they deem proper, on 
     certificates of responsible officers of the Company and certificates or 
     other written statements of officers of departments of various 
     jurisdictions having custody of documents respecting the corporate 
     existence or good standing of the Company and its subsidiaries, provided 
     that copies of any such statements or certificates shall be delivered to 
     Underwriters' Counsel.  The opinion of such counsel for the Company shall 
     state that the opinion of any such other counsel is in form satisfactory 
     to such counsel and, in their opinion, the Representatives and they are 
     justified in relying thereon.

          (c)  At the Closing Date and the Additional Closing Date the 
Representatives shall have received the favorable opinion of Weil Gotshal & 
Manges LLP, counsel for the Selling Stockholders, dated the Closing Date, 
addressed to the Underwriters and in form and substance satisfactory to 
Underwriters' Counsel, to the effect that:

               (i)  Each of this Agreement and the Selling Agreements has been
     duly and validly authorized, executed and delivered by or on behalf of each
     Selling Stockholder and is a valid and binding obligation of each Selling
     Stockholder, enforceable against such Selling Stockholder in accordance 
     with its terms, except to the extent that rights to indemnity hereunder 
     may be limited by applicable federal or state securities laws or the 
     public policy underlying such laws.

               (ii) The sale of the Shares or Warrants to be sold by such 
     Selling Stockholder hereunder, and the compliance by such Selling 
     Stockholder with all of the provisions of this Agreement and the Selling 
     Agreements and the consummation of the transactions herein and therein 
     contemplated will not conflict with or result in a breach or violation of 
     any terms or provisions of, or constitute a default under, any


                                          23
<PAGE>

     statute, indenture, mortgage, deed of trust, loan agreement or other
     agreement or instrument known to such counsel to which such Selling
     Stockholder is a party to or by which such Selling Stockholder is bound or 
     to which any of the properties or assets of such Selling Stockholder is 
     subject nor will such action result in any violation of the provisions of 
     the certificate of incorporation or bylaws of such Selling Stockholder if 
     such Selling Stockholder is a corporation, the partnership agreement of 
     such Selling Stockholder if such Selling Stockholder is a partnership, the 
     terms of any trust agreement if such Selling Stockholder is a trust or any 
     order, rule or regulation known to such counsel of any court or 
     governmental agency or body having jurisdiction over such Selling 
     Stockholder or other property of such Selling Stockholder.

               (iii)     To the best knowledge of such counsel, each Selling
     Stockholder has all requisite power and authority, and all necessary
     consents, approvals, authorizations, orders, registrations, filings,
     qualifications, licenses and permits of and from all courts and all public,
     governmental or regulatory agencies and bodies as are required for the
     execution, delivery and performance of this Agreement and the Selling
     Agreements and the consummation of the transactions contemplated hereby and
     thereby except for (1) such as may be required under state securities or 
     Blue Sky laws in connection with the purchase and distribution of the 
     Shares by the Underwriters (as to which such counsel need express no 
     opinion) and (2) such as have been made or obtained under the Act.

               (iv) Each Selling Stockholder has full legal right, power and
     authority (other than any approval imposed by the applicable federal or 
     state securities and Blue Sky laws) to enter into this Agreement, the 
     Power of Attorney and the Custody Agreement and to sell, assign, transfer 
     and deliver the Shares to be sold by such Selling Stockholder under this 
     Agreement.

               (v)  Upon delivery of the Shares and/or Warrants to be sold by 
     the Selling Stockholders pursuant to this Agreement and upon payment 
     therefor, good, valid and marketable title to such Shares and/or Warrants, 
     as the case may be, will pass to the Underwriters or their nominees, 
     severally, free and clear of all liens, encumbrances, equities or adverse 
     claims other than those arising as a result of any action taken by the 
     Underwriters, assuming that the Underwriters purchase such Shares and/or 
     Warrants in good faith and without notice of any adverse claims within the 
     meaning of the Uniform Commercial Code.

               (vi) The statements in the Prospectus under the caption 
     "Principal and Selling Stockholders," insofar as such statements 
     constitute a summary of the matters referred to therein, fairly present 
     the information called for with respect to such matters.

               In rendering such opinion, such counsel may rely (A) as to 
     matters involving the application of laws other than the laws of the 
     United States and jurisdictions in which they are admitted, to the extent 
     such counsel deems proper and to the extent specified in such opinion, if 
     at all, upon an opinion or opinions (in form and substance reasonably 
     satisfactory to Underwriters' Counsel) of other counsel reasonably 
     acceptable to Underwriters' Counsel, familiar with the applicable laws; (B)


                                          24
<PAGE>

     as to matters of fact, to the extent they deem proper, on certificates of, 
     or certificates of responsible officers of, the Selling Stockholders, 
     provided that copies of any such statements or certificates shall be 
     delivered to Underwriters' Counsel.  The opinions of such counsel for the 
     Selling Stockholders shall state that the opinion of any such other 
     counsel is in form satisfactory to such counsel and, in their opinion, 
     the Representatives and they are justified in relying thereon.

          (d)  At the Closing Date and Additional Closing Date, the 
Representatives shall have received a certificate of the Chairman of the 
Board and the Chief Financial Officer of the Company, dated the Closing Date 
or Additional Closing Date, as the case may be, to the effect that the 
condition set forth in subsection (a) of this Section 7 has been satisfied, 
that as of the date hereof and as of the Closing Date or Additional Closing 
Date, as the case may be, the representations and warranties of the Company 
set forth in Section 1 hereof are accurate, and that as of the Closing Date 
or the Additional Closing Date, as the case may be, the obligations of the 
Company to be performed hereunder on or prior thereto have been duly 
performed.

          (e)  At the Closing Date and, if applicable, the Additional Closing 
Date, the Representatives shall have received a certificate executed by the 
Attorney-in-Fact on behalf of each Selling Stockholder, dated the Closing 
Date, to the effect that the representations and warranties of such Selling 
Stockholder set forth in Section 2 hereof are accurate, and that as of the 
Closing Date or the Additional Closing Date, as the case may be, the 
obligations of such Selling Stockholder to be performed hereunder on or prior 
thereto have been duly performed.

          (f)  At the time this Agreement is executed and at the Closing Date 
and Additional Closing Date, the Representatives shall have received a letter 
from Ernst & Young LLP, independent public accountants for the Company, 
dated, respectively, as of the date of this Agreement and as of the Closing 
Date or Additional Closing Date, as the case may be, addressed to the 
Underwriters and in form and substance satisfactory to the Representatives, 
to the effect that: (i) they are independent certified public accountants 
with respect to the Company within the meaning of the Act and the applicable 
published rules and regulations of the Commission thereunder and stating that 
the answer to Item 10 of the Registration Statement is correct insofar as it 
relates to them; (ii) stating that, in their opinion,  the financial 
statements and schedules of the Company included in the Registration 
Statement and the Prospectus and covered by their opinion therein comply as 
to form in all material respects with the applicable accounting requirements 
of the Act and the applicable published rules and regulations of the 
Commission thereunder; (iii) stating that, on the basis of procedures (but 
not an examination made in accordance with generally accepted auditing 
standards) consisting of a reading of the latest available unaudited interim 
consolidated financial statements of the Company and its subsidiaries, a 
reading of the minutes of meetings and consents of the stockholders and 
boards of directors of the Company and its subsidiaries and the committees of 
such boards subsequent to December 31, 1996, inquiries of officers and other 
employees of the Company and its subsidiaries who have responsibility for 
financial and accounting matters of the Company and its subsidiaries with 
respect to transactions and events subsequent to December 31, 1996, and other 
specified procedures and inquiries to a date not more than five days prior to 
the date of such letter, nothing has come to their attention that would cause 
them to believe that: (A) the unaudited consolidated

                                          25
<PAGE>

financial statements and schedules of the Company included in the 
Registration Statement and the Prospectus do not comply as to form in all 
material respects with the applicable accounting requirements of the Act and 
the applicable published rules and regulations of the Commission thereunder 
or that such unaudited consolidated financial statements are not fairly 
presented in conformity with generally accepted accounting principles except 
to the extent certain footnote disclosures have been omitted in accordance 
with applicable rules of the Commission under the Exchange Act applied on a 
basis substantially consistent with that of the audited consolidated 
financial statements incorporated by reference in the Registration Statement 
and the Prospectus; (B) with respect to the period subsequent to December 31, 
1996, there were, as of the date of the most recent available monthly 
consolidated financial statements of the Company and its subsidiaries, if 
any, and as of a specified date not more than five days prior to the date of 
such letter, any changes in the capital stock or long-term indebtedness of 
the Company or any decrease in the net current assets or stockholders' equity 
of the Company, in each case as compared with the amounts shown in the most 
recent balance sheet incorporated by reference in the Registration Statement 
and the Prospectus, except for changes or decreases which the Registration 
Statement and the Prospectus disclose have occurred or may occur or which are 
set forth in such letter; or (C) that during the period from December 31, 
1996, to the date of the most recent available monthly consolidated financial 
statements of the Company and its subsidiaries, if any, and to a specified 
date not more than five days prior to the date of such letter, there was any 
decrease, as compared with the corresponding period in the prior fiscal year, 
in total revenues, or total or per share net income, except for decreases 
which the Registration Statement and the Prospectus disclose have occurred or 
may occur or which are set forth in such letter; and (iv) stating that they 
have compared specific dollar amounts, numbers of shares, percentages of 
revenues and earnings and other financial information pertaining to the 
Company and its subsidiaries set forth in the Registration Statement and the 
Prospectus, which have been specified by the Representatives prior to the 
date of this Agreement, to the extent that such amounts, numbers, percentages 
and information may be derived from the general accounting and financial 
records of the Company and its subsidiaries or from schedules furnished by 
the Company, and excluding any questions requiring an interpretation by legal 
counsel, with the results obtained from the application of specified 
readings, inquiries, and other appropriate procedures specified by the 
Representatives (which procedures do not constitute an examination in 
accordance with generally accepted auditing standards) set forth in such 
letter, and found them to be in agreement.

          (g)  All proceedings taken in connection with the sale of the Firm 
Shares and the Additional Shares as herein contemplated shall be satisfactory 
in form and substance to the Representatives and to Underwriters' Counsel, 
and the Underwriters shall have received from said Underwriters' Counsel a 
favorable opinion, dated as of the Closing Date and the Additional Closing 
Date, as the case may be, with respect to the sale of the Shares, the 
Registration Statement and the Prospectus and such other related matters, as 
the Representatives may reasonably require, and the Company and the Selling 
Stockholders shall have furnished to Underwriters' Counsel such documents as 
they request for the purpose of enabling them to pass upon such matters.

          (h)  Prior to the Closing Date and the Additional Closing Date, the 
Company and the Selling Stockholders shall have furnished to the 
Representatives such further information, certificates and documents as the 
Representatives may reasonably request.

                                          26
<PAGE>

          (i)  The Representatives shall have received from each person who 
is a director or officer of the Company or Selling Stockholder and each 
holder of capital stock of the Company listed on Schedule III attached 
hereto, a Lock-Up Agreement to the effect that such person will not (i) make 
a Disposition of any Securities now owned or hereinafter acquired by such 
person or with respect to which such person has or hereinafter acquires the 
power of disposition, for a period of 90 days after the date of the 
Prospectus otherwise than (A) as a bona fide gift or gifts, provided that the 
donee or donees thereof agree to be bound in writing by the terms of the 
Lock-Up Agreement, (B) as a distribution to limited partners or stockholders 
of such person provided that the distributees thereof agree in writing to be 
bound by the terms of the Lock-Up Agreement, or (C) without the prior written 
consent of the Representatives, or (ii) make any demand for or exercise any 
right with respect to the registration of any Common Stock or other 
Securities of the Company.

          (j)  The NASD, upon review of the terms of the public offering of 
the Firm Shares and the Additional Shares, shall not have objected to the 
Underwriters' participation in such offering.

          (k)  The Company shall not have sustained, (i) since December 31, 
1996, any loss or interference with its business from fire, explosion, flood 
or other calamity, whether or not covered by insurance, or from any labor 
dispute or court or governmental action, order of decree otherwise than as 
set forth or expressly contemplated in the Prospectus, and (ii) since the 
respective dates as of which information is given in the Prospectus, there 
shall not have been any change in the capital stock (other than as disclosed 
in the Prospectus) or increase in principal amounts of long-term or 
short-term indebtedness of the Company or any change, or any development 
involving a prospective change, in or affecting the general affairs, 
management, financial position, stockholders' equity or results of operations 
of the Company, otherwise than as set forth or expressly contemplated in the 
Prospectus, the effect of which, in any such case described in clause (i) or 
(ii) of this Section 7(k), in the Representatives' judgment, makes it 
impracticable or inadvisable to proceed with the public offering or the 
delivery of the Shares being delivered on the Closing Date or the Additional 
Closing Date, as the case may be, on the terms and in the manner contemplated 
in the Prospectus.

          If any of the conditions specified in this Section 7 shall not have 
been fulfilled when and as required by this Agreement, or if any of the 
certificates, opinions, written statements or letters furnished to the 
Representatives or to Underwriters' Counsel pursuant to this Section 7 shall 
not be in all material respects reasonably satisfactory in form and substance 
to the Representatives and to Underwriters' Counsel, all obligations of the 
Underwriters hereunder may be canceled by the Representatives at, or at any 
time prior to, the Closing Date and the obligations of the Underwriters to 
purchase the Additional Shares may be canceled by the Representatives at, or 
at any time prior to, the Additional Closing Date.  Notice of such 
cancellation shall be given to the Company and the Selling Stockholders in 
writing, or by telephone, telex or telegraph, confirmed in writing.

     8.   INDEMNIFICATION.

          (a)  The Company, USSC and each of the Selling Stockholders listed 
on Schedule II attached hereto under the caption "Control Selling 
Stockholders" (collectively, the

                                          27
<PAGE>

"CONTROL STOCKHOLDERS"), jointly and severally, agree to indemnify and hold 
harmless each Underwriter, its officers, directors, partners, employees, 
agents and counsel and each person, if any, who controls any Underwriter 
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange 
Act, against any and all losses, liabilities, claims, damages and expenses 
whatsoever (including, but not limited to, attorneys' fees and any and all 
expense whatsoever incurred in investigating, preparing or defending against 
any litigation, commenced or threatened, or any claim whatsoever, and any and 
all amounts paid in settlement of any claim or litigation), joint or several, 
to which they or any of them may become subject under the Act, the Exchange 
Act or otherwise, insofar as such losses, liabilities, claims, damages or 
expenses (or actions in respect thereof) arise out of or are based upon any 
untrue statement or alleged untrue statement of a material fact contained in 
the Registration Statement for the registration of the Shares, as originally 
filed or any amendment thereof, or any related preliminary prospectus or the 
Prospectus, or in any supplement thereto or amendment thereof, or arise out 
of or are based upon the omission or alleged omission to state therein a 
material fact required to be stated therein or necessary to make the 
statements therein not misleading; provided, however, that the Company, USSC 
and the Control Stockholders will not be liable in any such case to the 
extent but only to the extent that any such loss, liability, claim, damage or 
expense arises out of or is based upon any such untrue statement or alleged 
untrue statement or omission or alleged omission made therein in reliance 
upon and in conformity with written information furnished to the Company by 
or on behalf of any Underwriter through the Representatives expressly for use 
therein.  This indemnity will be in addition to any liability which the 
Company, USSC or the Control Stockholders may otherwise have, including under 
this Agreement.  Notwithstanding the foregoing, in no event shall any Control 
Stockholder, as such, be liable for indemnity under this Section 8 in any 
amount in excess of the gross proceeds received by such Control Stockholder 
in connection with the sale of his shares of Common Stock hereunder.  Without 
limiting the rights of any Underwriter or controlling person thereof, the 
provisions of this Section 8 shall not affect any existing arrangements among 
the Company and the Control Stockholders relating to indemnification.

          (b)  Each Selling Stockholder, severally and not jointly, agrees to 
indemnify and hold harmless each Underwriter, its officers, directors, 
partners, employees, agents and counsel, the Company, each of the directors 
of the Company, each of the officers of the Company who shall have signed the 
Registration Statement and each other person, if any, who controls the 
Company or any Underwriter, within the meaning of Section 15 of the Act or 
Section 20(a) of the Exchange Act, against any losses, liabilities, claims, 
damages and expenses whatsoever (including but not limited to attorneys' fees 
and any and all expenses whatsoever incurred in investigating, preparing or 
defending against any litigation, commenced or threatened, or any claim 
whatsoever, and any and all amounts paid in settlement of any claim or 
litigation), joint or several, to which they or any of them may become 
subject under the Act, the Exchange Act or otherwise, insofar as such losses, 
liabilities, claims, damages or expenses (or actions in respect thereof) 
arise out of or are based upon any untrue statement or alleged untrue 
statement of a material fact contained in the registration statement for the 
registration of the Shares, as originally filed or any amendment thereof, or 
any related preliminary prospectus or the Prospectus, or in any amendment 
thereof or supplement thereto, or arise out of or are based upon the omission 
or alleged omission to state therein a material fact required to be stated 
therein or necessary to make the statements therein not misleading, in each 
case to the extent, but only to the extent, that

                                          28
<PAGE>

any such loss, liability, claim, damage or expense arises out of or is based 
upon any such untrue statement or alleged untrue statement or omission or 
alleged omission made therein in reliance upon and in conformity with written 
information relating to such Selling Stockholder furnished to the Company by 
such Selling Stockholder expressly for use therein.  This indemnity will be 
in addition to any liability which any Selling Stockholder may otherwise 
have, including under this Agreement.

          (c)  Each Underwriter severally, and not jointly, agrees to 
indemnify and hold harmless the Company, each Selling Stockholder, each of 
the directors of the Company, each of the officers of the Company who shall 
have signed the Registration Statement, and each other person, if any, who 
controls the Company within the meaning of Section 15 of the Act or Section 
20(a) of the Exchange Act, against any losses, liabilities, claims, damages 
and expenses whatsoever (including but not limited to attorneys' fees and any 
and all expenses whatsoever incurred in investigating, preparing or defending 
against any litigation, commenced or threatened, or any claim whatsoever, and 
any and all amounts paid in settlement of any claim or litigation), joint or 
several, to which they or any of them may become subject under the Act, the 
Exchange Act or otherwise, insofar as such losses, liabilities, claims, 
damages or expenses (or actions in respect thereof) arise out of or are based 
upon any untrue statement or alleged untrue statement of a material fact 
contained in the Registration Statement for the registration of the Shares, 
as originally filed or any amendment thereof, or any related preliminary 
prospectus or the Prospectus, or in any amendment thereof or supplement 
thereto, or arise out of or are based upon the omission or alleged omission 
to state therein a material fact required to be stated therein or necessary 
to make the statements therein not misleading, in each case to the extent, 
but only to the extent, that any such loss, liability, claim, damage or 
expense arises out of or is based upon any such untrue statement or alleged 
untrue statement or omission or alleged omission made therein in reliance 
upon and in conformity with written information furnished to the Company by 
or on behalf of any Underwriter through the Representatives expressly for use 
therein; provided, however, that in no case shall any Underwriter be liable 
or responsible for any amount in excess of the underwriting discount 
applicable to the Shares purchased by such Underwriter hereunder.  This 
indemnity will be in addition to any liability which any Underwriter may 
otherwise have, including under this Agreement.  The Company and each Selling 
Stockholder acknowledge that the statements set forth in the last paragraph 
of the cover page, in the two paragraphs on the inside front cover page of 
the Prospectus and in the table listing the Underwriters under the caption 
"Underwriting" in the Prospectus constitute the only information furnished in 
writing by or on behalf of any Underwriter expressly for use in the 
Registration Statement relating to the Shares as originally filed or in any 
amendment thereof, any related preliminary prospectus or the Prospectus or in 
any amendment thereof or supplement thereto, as the case may be.

          (d)  Promptly after receipt by an indemnified party under 
subsection (a) or (b) above of notice of the commencement of any action, such 
indemnified party shall, if a claim in respect thereof is to be made against 
the indemnifying party under such subsection, notify each party against whom 
indemnification is to be sought in writing of the commencement thereof (but 
the failure so to notify an indemnifying party shall not relieve it from any 
liability which it may have under this Section 8 except to the extent that it 
has been prejudiced in any material respect by such failure or from any 
liability which it may have otherwise).  In case any such action is brought 
against any indemnified party, and the

                                          29
<PAGE>

indemnified party notifies an indemnifying party of the commencement thereof, 
the indemnifying party will be entitled to participate therein, and to the 
extent it may elect by written notice delivered to the indemnified party 
promptly after receiving the aforesaid notice from such indemnified party, to 
assume the defense thereof with counsel satisfactory to such indemnified 
party.  Notwithstanding the foregoing, the indemnified party or parties shall 
have the right to employ its or their own counsel in any such case, but the 
fees and expenses of such counsel shall be at the expense of such indemnified 
party or parties unless (i) the employment of such counsel shall have been 
authorized in writing by one of the indemnifying parties in connection with 
the defense of such action, (ii) the indemnifying parties shall not have 
employed counsel to have charge of the defense of such action within a 
reasonable time after notice of commencement of the action, or (iii) such 
indemnified party or parties shall have reasonably concluded that there may 
be defenses available to it or them which are different from or additional to 
those available to one or all of the indemnifying parties (in which case the 
indemnifying parties shall not have the right to direct the defense of such 
action on behalf of the indemnified party or parties), in any of which events 
such fees and expenses shall be borne by the indemnifying parties.  Anything 
in this subsection to the contrary notwithstanding, an indemnifying party 
shall not be liable for any settlement of any claim or action effected 
without its written consent; provided, however, that such consent was not 
unreasonably withheld.

     9.   CONTRIBUTION.  In order to provide for contribution in 
circumstances in which the indemnification provided for in Section 8(a), (b) 
and (c) hereof is for any reason held to be unavailable from the Company, 
USSC or any Selling Stockholder or is insufficient to hold harmless a party 
indemnified thereunder, the Company, USSC and the Selling Stockholders on the 
one hand and the Underwriters on the other hand shall contribute to the 
aggregate losses, claims, damages, liabilities and expenses of the nature 
contemplated by such indemnification provisions (including any investigation, 
legal and other expenses incurred in connection with, and any amount paid in 
settlement of, any action, suit or proceeding or any claims asserted, but 
after deducting in the case of losses, claims, damages, liabilities and 
expenses suffered by the Company, USSC and any Selling Stockholder any 
contribution received by the Company, USSC or such Selling Stockholder from 
persons, other than the Underwriters, who may also be liable for 
contribution, including persons who control the Company within the meaning of 
Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the 
Company who signed the Registration Statement and directors of the Company), 
to which the Company, USSC, one or more of the Selling Stockholders and one 
or more of the Underwriters may be subject, in such proportions as is 
appropriate to reflect the relative benefits received by the Company, USSC 
and the Selling Stockholders on the one hand and the Underwriters on the 
other hand from the offering of the Shares or, if such allocation is not 
permitted by applicable law or indemnification is not available as a result 
of the indemnifying party not having received notice as provided in Section 8 
hereof, in such proportion as is appropriate to reflect not only the relative 
benefits referred to above but also the relative fault of the Company, USSC 
and the Selling Stockholders on the one hand and the Underwriters on the 
other hand in connection with the statements or omissions which resulted in 
such losses, claims, damages, liabilities or expenses, as well as any other 
relevant equitable considerations.  The relative benefits received by the 
Company, USSC and the Selling Stockholders on the one hand and the 
Underwriters on the other hand shall be deemed to be in the same proportion 
as the total proceeds from the offering (net of underwriting discounts and 
commissions but before deducting expenses) received by the

                                          30
<PAGE>

Company, USSC and the Selling Stockholders on the one hand and the 
underwriting discounts and commissions received by the Underwriters, on the 
other hand, in each case as set forth in the table on the cover page of the 
Prospectus.  The relative fault of the Company, USSC and the Selling 
Stockholders on the one hand and of the Underwriters on the other hand shall 
be determined by reference to, among other things, whether the untrue or 
alleged untrue statement of a material fact or the omission or alleged 
omission to state a material fact relates to information supplied by the 
Company, USSC, the Selling Stockholders or the Underwriters and the parties' 
relative intent, knowledge, access to information and opportunity to correct 
or prevent such statement or omission.  The Company, USSC, the Selling 
Stockholders and the Underwriters agree that it would not be just and 
equitable if contribution pursuant to this Section 9 were determined by pro 
rata allocation (even if the Underwriters were treated as one entity for such 
purpose) or by any other method of allocation which does not take account of 
the equitable considerations referred to above.  The Company, USSC and each 
Selling Stockholder shall be jointly and severally liable for the amounts to 
be contributed by any of them pursuant to the provisions of this Section 9.

      Notwithstanding the provisions of this Section 9, (i) in no case shall 
any Underwriter (except as may be provided in the Agreement Among 
Underwriters) be liable or responsible for any amount in excess of the 
underwriting discount applicable to the Shares purchased by such Underwriter 
hereunder, and (ii) no person guilty of fraudulent misrepresentation (within 
the meaning of Section 11(a) of the Act) shall be entitled to contribution 
from any person who was not guilty of such fraudulent misrepresentation.  For 
purposes of this Section 9, each person, if any, who controls an Underwriter 
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange 
Act shall have the same rights to contribution as such Underwriter, each 
person, if any, who controls a Selling Stockholder within the meaning of 
Section 15 of the Act or Section 20(a) of the Exchange Act shall have the 
same rights to contribution as such Selling Stockholder, and each person, if 
any, who controls the Company within the meaning of Section 15 of the Act or 
Section 20(a) of the Exchange Act, each officer of the Company who shall have 
signed the Registration Statement and each director of the Company shall have 
the same rights to contribution as the Company, subject in each case to 
clauses (i) and (ii) of this Section 9. Any party entitled to contribution 
will, promptly after receipt of notice of commencement of any action, suit or 
proceeding against such party in respect of which a claim for contribution 
may be made against another party or parties under this Section 9, notify 
such party or parties from whom contribution may be sought, but the omission 
to so notify such party or parties shall not relieve the party or parties 
from whom contribution may be sought from any obligation it or they may have 
under this Section 9 or otherwise.  No party shall be liable for contribution 
with respect to any action or claim settled without its consent; provided, 
however, that such consent was not unreasonably withheld.

     10.  DEFAULT BY AN UNDERWRITER.

For purposes of this Section 10, references to the purchase by an Underwriter 
of Firm Shares or Additional Shares shall include the purchase of the 
Underwriter's proportional share of Firm Warrants or Additional Warrants, as 
the case may be, from the Selling Stockholders, and the exercise of such Firm 
Warrants or Additional Warrants by such Underwriter pursuant to Section 3 
hereof.

                                          31
<PAGE>

          (a)  If any Underwriter or Underwriters shall default in its or 
their obligation to purchase Firm Shares or Additional Shares hereunder, and 
if the Firm Shares or Additional Shares with respect to which such default 
relates do not (after giving effect to arrangements, if any, made by the 
Representatives pursuant to subsection (c) below) exceed in the aggregate 10% 
of the number of shares of Firm Shares or Additional Shares, as the case may 
be, which all Underwriters have agreed to purchase hereunder, then such Firm 
Shares or Additional Shares to which the default relates shall be purchased 
by the non-defaulting Underwriters in proportion to the respective 
proportions which the numbers of Firm Shares set forth opposite their 
respective names on Schedule I attached hereto bear to the aggregate number 
of Firm Shares set forth opposite the names of the non-defaulting 
Underwriters.

          (b)  In the event that such default relates to more than 10% of the 
Firm Shares or Additional Shares, as the case may be, the Representatives 
may, in their sole discretion, arrange for themselves or for another party or 
parties (including any non-defaulting Underwriter or Underwriters who so 
agree) to purchase such Firm Shares or Additional Shares, as the case may be, 
to which such default relates on the terms contained herein.  In the event 
that within five calendar days after such a default the Representatives do 
not arrange for the purchase of the Firm Shares or Additional Shares, as the 
case may be, to which such default relates as provided in this Section 10, 
this Agreement or, in the case of a default with respect to the Additional 
Shares, the obligations of the Underwriters to purchase and of the Selling 
Stockholders to sell the Additional Shares shall thereupon terminate, without 
liability on the part of the Company or the Selling Stockholders with respect 
thereto (except in each case as provided in Sections 6, 8(a) and (b) and 9 
hereof) or the several Underwriters, but nothing in this Agreement shall 
relieve a defaulting Underwriter or Underwriters of its or their liability, 
if any, to the other several Underwriters, the Company and the Selling 
Stockholders for damages occasioned by its or their default hereunder.

          (c)  In the event that the Firm Shares or Additional Shares to 
which the default relates are to be purchased by the non-defaulting 
Underwriters or are to be purchased by another party or parties as aforesaid, 
the Representatives or the Company shall have the right to postpone the 
Closing Date or Additional Closing Date, as the case may be, for a period, 
not exceeding five business days, in order to effect whatever changes may 
thereby be made necessary in the Registration Statement or the Prospectus or 
in any other documents and arrangements and the Company agrees to file 
promptly any amendment or supplement to the Registration Statement or the 
Prospectus which, in the opinion of Underwriters' Counsel, may thereby be 
made necessary or advisable.  The term "UNDERWRITER" as used in this 
Agreement shall include any party substituted under this Section 10 with like 
effect as if it had originally been a party to this Agreement with respect to 
such Firm Shares and Additional Shares.

     11.  SURVIVAL OF REPRESENTATIONS AND AGREEMENTS.  All representations 
and warranties, covenants and agreements of the Underwriters, the Selling 
Stockholders and the Company contained in this Agreement, including the 
agreements contained in Section 6, the indemnity agreements contained in 
Section 8 and the contribution agreements contained in Section 9, shall 
remain operative and in full force and effect regardless of any investigation 
made by or on behalf of any Underwriter or any controlling person thereof or 
by or on behalf

                                          32
<PAGE>

of the Company, any of its officers and directors or any Selling Stockholder 
or any controlling person thereof, and shall survive delivery of and payment 
for the Shares to and by the several Underwriters.  The representations 
contained in Sections 1 and 2 and the agreements contained in Sections 6, 8, 
9 and 12(d) hereof shall survive the termination of this Agreement, including 
pursuant to Sections 10 or 12 hereof.

     12.  EFFECTIVE DATE OF AGREEMENT; TERMINATION.

          (a)  This Agreement shall become effective (i) if Rule 430A under 
the Act is not used, when the Representatives, the Company and the Selling 
Stockholders shall have received notification of the effectiveness of the 
Registration Statement, or, if Rule 430A under the Act is used, when the 
parties hereto have executed and delivered this Agreement.  If either the 
initial public offering price or the purchase price per Share has not been 
agreed upon prior to 5:00 p.m., New York time, on the fifteenth full business 
day after the Registration Statement shall have become effective, this 
Agreement shall thereupon terminate without liability to the Company, USSC, 
the Selling Stockholders or the Underwriters except as herein expressly 
provided.  Until this Agreement becomes effective as aforesaid, it may be 
terminated by the Company by notifying the Representatives and the Selling 
Stockholders or by joint action only of the Selling Stockholders directly or 
the Attorney-in-Fact on behalf of all the Selling Stockholders by notifying 
the Company and the Representatives or by the Representatives notifying the 
Company, USSC and the Selling Stockholders.  Notwithstanding the foregoing, 
provisions of this Section 12 and of Sections 1, 2, 6, 8 and 9 hereof shall 
at all times be in full force and effect.

          (b)  The Representatives shall have the right to terminate this 
Agreement and the obligations of the Underwriters hereunder at any time prior 
to the Closing Date (and, with respect to the Additional Shares, the 
Additional Closing Date) by notice to the Company from the Representatives, 
without liability (other than with respect to Sections 8 and 9 hereof) on the 
part of any Underwriter, to the Company and the Selling Stockholders if, on 
or prior to such date, (i) the Company or any Selling Stockholder shall have 
filed, refused or been unable to perform in any material respect any 
agreement on its, his or her part to be performed hereunder, (ii) any other 
condition to the Underwriters' obligations hereunder set forth in Section 7 
is not fulfilled when and as required in any material respect, (iii) trading 
in securities on the New York or American Stock Exchanges or in the 
over-the-counter market shall have been suspended or materially limited, or 
minimum or maximum prices shall have been established or maximum price ranges 
for prices for securities shall have been required, on the New York or 
American Stock Exchanges or in the over-the-counter market by the Commission, 
or by such exchange or other regulatory body or governmental authority having 
jurisdiction, (iv) a general banking moratorium shall have been declared by a 
federal or state authority or any new restriction materially and adversely 
affecting the Firm Shares or the Additional Shares, as the case may be, shall 
have become effective, (v) there shall have occurred an outbreak or 
escalation of armed hostilities involving the United States on or after the 
date hereof, or if there has been a declaration by the United States of a 
national emergency or war, the effect of which shall be, in the 
Representatives' judgment, to make it inadvisable or impracticable to proceed 
with the sale and delivery of the Shares on the terms and in the manner 
contemplated in the Prospectus, (vi) in the Representatives' opinion any 
material adverse change shall have occurred since the respective dates as of 
which information is given in the Registration Statement or the Prospectus in 
the condition

                                          33
<PAGE>

(financial or otherwise) of the Company and its subsidiaries taken as a 
whole, whether or not arising in the ordinary course of business other than 
as set forth in the Prospectus, or (vii) there shall have occurred such a 
material adverse change in general economic, political or financial 
conditions or if the effect of international conditions on the financial 
markets in the United States shall be such as, in the Representatives' 
judgment, makes it inadvisable or impracticable to proceed with the sale and 
delivery of the Firm Share or the Additional Shares, as the case may be, on 
the terms contemplated hereby and by the Prospectus.  The rights of the 
Representatives to terminate this Agreement will not be waived or otherwise 
relinquished by their failure to give notice of termination prior to the time 
that the event giving rise to the right to terminate shall have cased to 
exist, provided that notice is given prior to the Closing Date (and, with 
respect to the Additional Shares, the Additional Closing Date).

          (c)  Any notice of termination pursuant to this Section 12 shall be 
by telephone, telex, or telegraph, confirmed in writing by letter.

          (d)  If this Agreement shall be terminated pursuant to any of the 
provisions hereof (otherwise than pursuant to (i) notification by the 
Representatives as provided in Section 12(a) hereof or (ii) Sections 10(b) or 
12(b) hereof (except clauses (i), (ii) and (vi))), or if the sale of the 
Shares provided for herein is not consummated because any condition to the 
obligations of the several Underwriters set forth herein is not satisfied or 
because of any refusal, inability or failure on the part of the Company or 
any Selling Stockholder to perform any agreement herein or comply with any 
provision hereof, the Company and the Selling Stockholders jointly and 
severally agree, upon demand by the Representatives, to reimburse the 
Underwriters for all out-of-pocket expenses (including the fees and expenses 
of their counsel), incurred by the several Underwriters in connection 
herewith.

     13.  NOTICE.  All communications hereunder, except as may be otherwise 
specifically provided herein, shall be in writing and, if sent to any 
Underwriter, shall be mailed, delivered, telexed or telegraphed and confirmed 
in writing, to such Underwriter c/o Bear, Stearns & Co. Inc., 245 Park 
Avenue, New York, NY 10167, Attention: Corporate Finance Department; if sent

address set forth on Schedule II attached hereto.

     14.  PARTIES.  The Representatives represent that they are authorized to 
act on behalf of the several Underwriters named on Schedule I attached 
hereto, and the Company and the Selling Stockholders shall be entitled to act 
and rely on any request, notice, consent, waiver or agreement purportedly 
given on behalf of the Underwriters when the same shall have been given by 
the Representatives on such behalf.  This Agreement shall inure solely to the 
benefit of, and shall be binding upon, the several Underwriters, the Selling 
Stockholders, the Company and USSC and the controlling persons, directors, 
officers, employees and agents referred to in Sections 8 and 9, and their 
respective successors and assigns, and no other person shall have or be 
construed to have any legal or equitable right, remedy or claim under or in 
respect of or by virtue of this Agreement or any provision herein

                                          34
<PAGE>

contained.  The term "successors and assigns" shall not include a purchaser, 
in its capacity as such, of Shares from any of the Underwriters.

     15.  GOVERNING LAW.  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE 
WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES 
OF CONFLICTS OF LAWS.

     16.  COUNTERPARTS.  This Agreement may be executed by any one or more 
parties hereto in any number of counterparts, each of which shall be deemed 
to be an original, but all such counterparts shall together constitute one 
and the same instrument.

     17.  PARTIAL INVALIDITY. In case any provision of this Agreement shall 
be invalid, illegal or unenforceable, the validity, legality and 
enforceability of the remaining provisions shall not in any way be affected 
or impaired thereby.

                             Management Equity Plan



1.   PURPOSE

     United Stationers Inc., a Delaware corporation (the "Company"), by means of
this  Management Equity Plan (the "Plan") desires to afford certain of its
directors, key employees and the key employees of any parent corporation or
subsidiary corporation thereof now existing or hereafter formed or acquired who
are responsible for the continued growth of the Company an opportunity to
acquire a proprietary interest in the Company, and thus to create in such
persons an increased interest in and a greater concern for the welfare of the
company and any parent corporation or subsidiary corporation thereof.  As used
in the Plan, the terms "parent corporation" and "subsidiary corporation" shall
mean, respectively, a corporation within the definition of such terms contained
in Sections 424(e) and 424(f), respectively, of the Internal Revenue Code of
1986, as amended (the "Code").

     The stock options described in Section 6 (the "Options"), and the shares of
common stock of the Company acquired pursuant to the exercise of such Options
are a matter of separate inducement and are not in lieu of any salary or other
compensation for services.

2.   ADMINISTRATION

     The Plan shall be administered by the Option Committee, or any successor
thereto, of the Board of Directors of the Company or by such other committee, as
determined by the Board (the "Committee").  The Committee shall consist of not
less than two members of the Board of Directors of the Company, each of whom
shall qualify as a "disinterested person" to administer the Plan within the
meaning of Rule 16b-3, as amended, or other applicable Rules under Section 16(b)
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The
Committee shall administer the Plan so as to comply at all times with the
Exchange Act. A majority of the Committee shall constitute a quorum, and subject
to the provisions of Section 5, the acts of a majority of the members present at
any meeting at which a quorum is present, or acts approved in writing by a
majority of the Committee, shall be the acts of the Committee.

3.   SHARES AVAILABLE

     Subject to the adjustments provided in Section 7, the maximum aggregate
number of shares of common stock of the Company which may be granted for all
purposes under the Plan shall be 4,100,000 shares.  If, for any reason, any
shares as to which Options have been granted cease to be subject to purchase
thereunder, including, without limitation, the expiration of such Option, the
termination of such option prior to exercise or the forfeiture of such Option,
such shares shall thereafter be available for grants to such individual or other
individuals under the Plan.  Options granted under the Plan may be fulfilled in
accordance with the terms of the Plan with either authorized and unissued shares
of the common stock of the Company or issued shares of such common stock held in
the Company's treasury.

officers and directors of the Company, or any parent corporation or subsidiary
corporation thereof, who are regularly employed on a salaried basis and who are
so employed on the date of such grant (the "Officer and Key Employee
Participants"), or who are non-employee directors of the Company on the date of
such grant.

5.   AUTHORITY OF COMMITTEE

     Subject to and not inconsistent with the express provisions of the Plan and
the Code, the Committee shall have plenary authority, in its sole discretion,
to:

     a.   determine the persons to whom Options shall be granted, the time when
          such Options shall be granted, the number of Options, the purchase
          price or exercise price of each Option, the period(s) during which
          such Option shall be exercisable (whether in whole or in part), the
          restrictions to be applicable to Options and the other terms and
          provisions thereof (which need not be identical);

     b.   require, as a condition to the granting of any Option, that the person
          receiving such Option agree not to sell or otherwise dispose of such
          Option, any common stock acquired pursuant to such Option or any other
          "derivative security" (as defined by Rule 16a-l(c) under the Exchange
          Act) for a period of at least six (6) months following the later of
          (i) the date of the grant of such Option or (ii) the date when the
          exercise price of such Option is fixed if such exercise price is not
          fixed at the date of grant of such Option:

     c.   provide an arrangement through registered broker-dealers whereby
          temporary financing may be made available to an optionee by the
          broker-dealer, under the rules and regulations of the Federal Reserve
          Board, for the purpose of assisting the optionee in the exercise of an
          Option, such authority to include the payment by the Company of the
          commissions of the broker-dealer:

     d.   provide the establishment of procedures for an optionee (1) to have
          withheld from the total number of shares to be acquired upon the
          exercise of an Option that number of Shares having a Fair Market Value
          (as defined in Section 9) which, together with such cash as shall be
          paid in respect of fractional Shares, shall equal the Option exercise
          price, and (2) to exercise a portion of an Option by delivering that
          number of shares already owned by such optionee having a Fair Market
          Value which shall equal the partial Option exercise price and to
          deliver the shares thus acquired by such optionee in payment of shares
          to be received pursuant to the exercise of additional portions of such
          Option, the effect of which shall be that such optionee can in
          sequence utilize such newly acquired shares in payment of the exercise
          price of the entire Option, together with such cash as shall be paid
          in respect of fractional shares;

     e.   provide the establishment of a procedure whereby a number of shares of
          common stock or other securities may be withheld from the total number
          of

                                        2

<PAGE>

          shares of common stock or other securities to be issued upon exercise
          of an Option to meet the obligation of withholding for taxes incurred
          by an optionee upon such exercise;

     f.   prescribe, amend, modify and rescind rules and regulations relating to
          the Plan;

     g.   make all determinations specified in or permitted by the Plan or
          deemed necessary or desirable for its administration or for the
          conduct of the Committee's business; and

          its responsibilities under the Plan.

     The Committee may delegate to one or more of its members, or to one or more
agents, such administrative duties as it may deem advisable, and the Committee
or any person to whom it has delegated duties as aforesaid may employ one or
more persons to render advice with respect to any responsibility the Committee
or such person may have under the Plan; PROVIDED, HOWEVER, that the Committee
may not delegate any duties to a member of the Board of Directors of the Company
who, if elected to serve on the Committee, would not qualify as a "disinterested
person" to administer the Plan as contemplated by Rule 16b-3, as amended, or
other applicable rules under the Exchange Act.  The Committee may employ
attorneys, consultants, accountants, or other persons and the committee, the
Company, and its officers and directors shall be entitled to rely upon the
advice, opinions or valuations of any such persons.  All actions taken and all
interpretations and determinations made by the Committee in good faith shall be
final and binding upon all persons who have received grants under the Plan, the
company and all other interested persons.  No member or agent of the Committee
shall be personally liable for any action, determination or interpretation made
in good faith with respect to the Plan and all members and agents of the
Committee shall be fully protected by the Company in respect of any such action,
determination or interpretation.

6.   GRANTS OF STOCK OPTIONS

     The Committee shall have the authority, in its sole discretion, to grant
incentive stock options ("Incentive Options") pursuant to Section 422 of the
Code, or to grant non-qualified stock options ("Non-Qualified 0ptions") (options
which do not qualify under Section 422 of the Code) or to grant both types of
Options.  No option shall be granted for a term of more than ten (10) years.
Notwithstanding anything contained herein to the contrary, an Incentive Option
may be granted only to Officer and key Employee Participants. The terms and
conditions of the Options shall be determined from time to time by the
Committee:  PROVIDED, HOWEVER, that the Options granted under the Plan shall be
subject to the following:

          a.   OPTION PRICE.  The Committee shall establish the option price at
          the time any Option is granted at such amount as the Committee shall
          determine.  The option price for each share purchasable under any
          Incentive Option granted hereunder shall be such amount as the
          Committee shall, in its best judgment, determine to be not less than
          one hundred percent (100%) of the Fair Market Value per share at the
          date the Option is granted; PROVIDED, HOWEVER, that in the case of an
          Incentive Option granted to a person who, at the time such Incentive
          Option is granted, owns shares of the Company, or any parent
          corporation or subsidiary corporation thereof, which possess more than
          ten percent (10%) of

                                        3

<PAGE>

          the total combined voting power of all classes of shares of the
          Company or of any subsidiary corporation or parent corporation of the
          Company, the purchase price for each share shall be such amount as the
          Committee, in its best judgment, shall determine to be not less than
          one hundred ten percent (110%) of the Fair Market Value per share at
          the date the Option is granted.  The Option price will be subject to
          adjustment in accordance with the provisions of Section 7 of the Plan.

          b.   PAYMENT.  The price per share of common stock of the Company with
          respect to each Option shall be payable at the time the Option is
          exercised.  Such price shall be payable in cash, which may be paid by
          wire transfer in immediately available funds, by check or by any other
          instrument acceptable to the Company or, in the discretion of the
          Committee, by delivery to the Company of shares or common stock of the
          Company owned by the optionee or by the Company withholding from the
          total number of shares to be acquired pursuant to the Option a portion
          of such shares.  Shares delivered to or withheld by the Company in
          payment of the option price shall be valued at the Fair Market Value
          of the common stock of the Company on the day preceding the date of
          the exercise of the option.

          c.   CONTINUATION OF EMPLOYMENT.  Notwithstanding anything else
          contained herein, each Option by its terms shall require the optionee
          to remain in the continuous employ of, or as a director of, the
          Company, or any parent corporation or subsidiary corporation thereof,
          for at least six (6) months (or three (3) months in the case of an
          Incentive Option) from the date of grant of the Option before the
          right to exercise any part of the Option will accrue.

          d.   EXERCISABILITY OF STOCK OPTION.  Each Option shall be exercisable
          in such installments as may be determined by the Committee at the time
          of the grant.  The right to purchase shares shall be cumulative so
          that when the right to purchase any shares has accrued such shares or
          any part thereof may be purchased at any time thereafter until the
          expiration or termination of the Option.  No Option by its terms shall
          be exercisable after the expiration of ten (10) years from the date of
          the grant of the Option; PROVIDED, HOWEVER, in the case of an
          Incentive Option granted to a person who, at the time such Option is
          granted, owns stock of the Company, or any parent corporation or
          subsidiary corporation thereof, possessing more than ten percent (10%)
          of the total combined voting power of all classes of stock of the
          Company, or any corporation or subsidiary corporation thereof, such
          Option shall not be exercisable after the expiration of five (5) years
          from the date such Option is granted.

          e.   DEATH.  In the event of the death of any optionee, the estate of
          such optionee shall have the right, within the period designated by
          the Committee at the time of grant, which shall in no event be less
          than within six (6) months after the date of death (but not after the
          expiration date of the Option), to exercise such optionee's Option
          with respect to all or any part of the shares of stock which such
          optionee was entitled to purchase immediately prior to the time of his
          death, or will become entitled to purchase during the period of
          exercise.

                                        4

<PAGE>


          f.   DISABILITY OR RETIREMENT.     If the employment of any optionee
          is terminated because of Disability (as defined in Section 9), or
          because of retirement, such optionee shall have the right, within the
          period designated by the Committee at the time of grant, which shall
          in no event be less that within six (6) months after the date of
          termination (or within one (1) year after the date of such termination
          in the case of an Incentive Option) (but in no case after the
          expiration of the Option), to exercise the Option with respect to all
          or any part of the shares of stock which such optionee was entitled to
          purchase immediately prior to the time of such termination, or will
          become entitled to purchase during the period of exercise.

          g.   OTHER TERMINATION OR FOR CAUSE.  If the employment of an optionee
          is terminated for any reason other than those specified in the
          subsections 6(e) and (f) above, such optionee shall have the right,
          within the period designated by the Committee which shall in no event
          be less than thirty (30) days (or three (3) months in the case of an
          Incentive Option) after the date of such termination (but not after
          the expiration date of the Option), to exercise his Option with
          respect to all or any part of the shares of stock which such optionee
          was entitled to purchase immediately prior to the time of such
          termination, except that, if such optionee's employment was terminated
          by the Company, or any parent corporation or subsidiary corporation
          thereof, for good cause, or if the optionee voluntarily terminates
          employment without the consent of the Company, or any parent
          corporation or subsidiary corporation thereof (of which fact the
          Committee shall be the sole judge), such optionee shall immediately
          forfeit all rights under his Option except as to the shares of stock
          already purchased.   Termination for "good cause" shall mean (unless
          another definition is agreed to in writing by the Company and the
          optionee) termination by action of the Board of Directors because of:
          (A) the optionee's theft or embezzlement, or attempted theft or
          embezzlement, of money or tangible or intangible assets or property of
          the Company or any parent corporation or subsidiary corporation
          thereof, (B) any act or acts of moral turpitude by optionee, (C) other
          than as a result of a Disability, optionee's failure to devote
          adequate time to the Company's or such parent corporation's or such
          subsidiary corporation's business as determined in the reasonable
          judgment of the Board of Directors, after having given notice of the
          asserted problem and a reasonable opportunity to cure, (D) any
          intentional acts by optionee which establish optionee's loyalty to a
          business entity or person other than the Company, (E) gross negligence
          or willful misconduct in the performance of optionee's duties, (F)
          conviction of a felony, (G) conviction of a crime, the conviction of
          which results in a material injury to the Company or any parent
          corporation or subsidiary corporation thereof, or (H) a willful
          material breach of any employment agreement entered into between
          optionee and the Company or any parent corporation or subsidiary
          corporation thereof.  The determination that there exists "good cause"
          for termination shall be made by the Option Committee (unless
          otherwise agreed to in writing by the Company and the optionee) and
          such determination shall be conclusive.

          h.   MAXIMUM EXERCISE.  The aggregate Fair Market Value of stock
          (determined at the time of the grant of the Option) with respect to
          which Incentive Options are exercisable for the first time by an
          optionee during any

                                        5

<PAGE>

          calendar year under all plans of the Company, or any parent
          corporation or subsidiary corporation thereof, shall not exceed
          $100,000.

          i.   LIMIT ON INDIVIDUAL GRANTS.   In any calendar year, the maximum
          number of shares for which options may be granted under the Plan to
          any one optionee is 400,000 shares of common stock (subject to
          adjustment in accordance with Section 7 of the Plan.

7.   ADJUSTMENT OF SHARES


     In the event there is any change in the common stock of the Company by
reason of any consolidation, combination, liquidation, reorganization,
recapitalization , stock dividend, stock split, split-up, split-off, spin-off,
combination of shares, exchange of shares or other like change in the capital
structure of the Company, the number or kind of shares or interests subject to
an Option and the per share price or value thereof shall be appropriately
adjusted by the Committee at the time of such event, provided that each
optionee's position with respect to the Option and the per share price or value
thereof shall not, as a result of such adjustment, be worse than it had been
immediately prior to such event.  Any fractional shares or interests resulting
from such adjustment shall be eliminated.  Notwithstanding the foregoing, (I)
each such adjustment with respect to an Incentive Option shall comply with the
rules of Section 424(a) of the Code, and (ii) in no event shall nay adjustment
be made which would render any Incentive Option granted hereunder other than an
"incentive stock option" for purposes of Section 422 of the Code.

     In the event of a Change of Control or a merger between the Company and
another  corporation in which the Company is not the surviving entity and where
any optionee holds Options issued pursuant to this Plan which have not been
exercised, such Options shall be canceled and replacement Options shall be
issued by the surviving entity in accordance with Rule 16b-3(f)(1) under the
Exchange Act.

8.   MISCELLANEOUS PROVISIONS

          a.   ASSIGNMENT OR TRANSFER.  The Committee may, in its discretion,
          authorize all or a portion of the options, other than Incentive Stock
          Options, to be granted to an optionee to be on terms which permit
          transfer by such optionee to (i) the spouse, children or grandchildren
          of the optionee ("Immediate Family Members"), (ii) a trust or trusts
          for the exclusive benefit of such Immediate Family Members, or (iii) a
          partnership in which such Immediate Family Members are the only
          partners, provided that (x) there may be no consideration for any such
          transfer, (y) the stock option agreement pursuant to which such
          options are granted must be approved by the Committee and must
          expressly provide for transferability in a manner consistent with this
          Section, and (z) subsequent transfers of transferred options shall be
          prohibited except by will or the laws of descent and distribution.
          Following transfer, any such options shall continue to be subject to
          the same terms and conditions as were applicable immediately prior to
          transfer."


          b.   INVESTMENT REPRESENTATION.  If a registration statement under the
          Securities Act of 1933, as amended (the "Securities Act"), with
          respect to the

                                        6

<PAGE>

          common stock issuable upon exercise of an Option, is not in effect at
          the time such Option is exercised, the Company may require, for the
          sole purpose of complying with the Securities Act, that prior to
          delivering such common stock to the exercising optionee, such optionee
          must deliver to the Secretary of the Company a written statement (i)
          representing and warranting that such common stock is being acquired
          for investment only and not with a view to the resale or distribution
          thereof, (ii) acknowledging and confirming that such common stock may
          not be sold unless registered for sale under the Securities Act or
          pursuant to an exemption from such registration and (iii) agreeing
          that the certificates representing such common stock shall bear a
          legend to the effect of the foregoing.

          If subsequent to the delivery by an optionee of the written statement
          described in the preceding paragraph, the common stock issuable upon
          exercise of an Option is registered under the Securities Act, the

         200 East Randolph
         Chicago, Illinois 60601

following the expiration of the Extended Term.

    (d)  The "Right of First Notification" provision appearing at the end of
Rider No. One of the Lease is hereby deleted in its entirety and the following
substituted therefor:

         "RIGHT OF FIRST OFFER. If at any time during the Extended Term,
         that certain space contiguous to the Demised Premises depicted on
         Exhibit B hereto and containing approximately 135,508 square feet
         (the "Option Space") becomes available for leasing, and if no
         Event of Default by Tenant exists under the Lease, then Landlord
         shall not lease such Option Space to any third party without
         first giving Tenant (i) notice of the availability of such space
         which shall include the proposed term and rental rate (including

         three (3) business days after the date of such notice in which to
         commit in writing to lease such Option Space on the Offered Terms

         Term may be longer or shorter than that proposed by Landlord, and
         otherwise on the terms, covenants and conditions contained in the
         Lease. Landlord and Tenant expressly agree that the Offered
         Terms, in any event, shall limit Landlord's liability for the
         payment of a brokerage commission to any Tenant's broker to the
         payment of the then current market expansion commission (i.e., a
         commission equal to 50% of the then market commission payable to
         outside brokers in connection with new leases of space in the
         Building).


<PAGE>

         If Tenant fails, refuses or is otherwise unable to commit to such
         a lease within the three (3) business day period, Landlord shall
         have the right to lease the Option Space to any third party or
         parties on such terms as are acceptable to Landlord."

nor its officers or agents nor anyone acting on its behalf has dealt with any
real estate broker, other than LaSalle Partners and Grubb & Ellis (the fees of
which shall be payable by Landlord) in the negotiation or making of this First
Amendment and Tenant agrees to indemnify and hold harmless Landlord from any and
all claims, liability, costs and expenses (including attorneys' fees) incurred
as a result of any inaccuracy in the foregoing representation and warranty.

     8.   FULL FORCE AND EFFECT: INCONSISTENCY. Except as otherwise expressly
set forth in this First Amendment, all provisions of the Lease shall remain in
full force and effect. In the event of any inconsistency between the terms of
the Lease and the terms of this First Amendment, the terms of this First
Amendment shall control.

     IN WITNESS WHEREOF, the parties have executed this First Amendment as of
the day and year first above written.

the Company from asserting such fact or circumstance in enforcing the Company's
rights hereunder.

                   paid;

              (3)  a pro rata Target Award for the year in which the

                   established with respect to the year in which the
                   termination of the Executive's employment occurs are met;

              (4)  an amount equal to (i) 2 multiplied by (ii) the sum of (x)

                   remain exercisable until the earlier of (i) the end of the
                   Severance Period or (ii) the date the options would
                   otherwise expire;

                   (C)  provided that the daily closing price of the Common
                        Stock has been equal to or greater than $40.00 for at
                        least 80 of

                        held by the Executive as of the date of the
                        termination of his employment shall continue to
                        become exercisable until the end of the Severance
                        Period as if the Executive were still an employee,
                        and any such portion of Tranches 1, 2 and/or 3 that
                        becomes exercisable during the Severance period shall

                        would otherwise expire;

               (7)  if (x) the termination of the Executive's employment
                    under this Section 12(d) occurs during any
                    100-consecutive-trading-day period following the date
                    that the daily closing price of the Common Stock is equal
                    to or greater than $40.00 (a "100-Day Period") and (y)
                    during any such 100-Day Period the daily closing price of
                    the Common Stock has not been equal to nor greater than
                    $40.00 for at least 80 of such 100 consecutive trading
                    days, then the unexercisable portion of Tranche 3 held by
                    the Executive as of the date of the termination of his
                    employment shall be forfeited by the Executive as of such
                    date; and if (A) the termination of the Executive's
                    employment under this Section 12(d) occurs during any
                    100-Day Period and (B) during such 100-Day Period the

                    or greater than $40.00 for at least 80 of such 100
                    consecutive trading days, then the unexercisable portion
                    of Tranche 3 held by the Executive as of the date of the
                    termination of his employment shall continue to become
                    exercisable as if he were still an employee of the
                    Company, and any such portion of Tranche 3 that becomes
                    exercisable during the Severance Period shall remain
                    exercisable until the earlier of (i) the end of the
                    Severance Period or (ii) the date the options would
                    otherwise expire;

               (8)  continuation of the lease with respect to the automobile
                    provided by the Company in accordance with Section 10(b) (3)
                    above until the earlier of (i) the end of the Severance
                    Period or (ii) the date such lease would otherwise expire;

               (9)  continuation of all perquisites provided by the Company to
                    the Executive under Section l0 above, other than
                    reimbursement of the club business expense portion of
                    Section 10(b)(1) above, until the end of the Severance
                    Period;

               (10) any amounts earned, accrued or owing to the Executive but
                    not yet paid under Section 7, 8, 9, 10 or 11 above;

               (11) continued participation, as if he were still an employee, in
                    the Company's medical, dental, hospitalization, life and
                    disability insurance plans, programs and/or arrangements and
                    in other employee benefit plans, programs and/or
                    arrangements in which


<PAGE>

                    he was participating on the date of the termination of his
                    employment until the earlier of:

                    (A)  the end of the Severance Period; or

                    (B)  the date, or dates, he receives equivalent coverage and
                         benefits under the plans, programs and/or arrangements
                         of a Subsequent employer (such coverage and benefits to
                         be determined on a coverage-by-coverage or
                         benefit-by-benefit basis)

                    PROVIDED, HOWEVER, that:

                    (X)  if the Executive is precluded from continuing his
                         participation in any employee benefit plan, program or
                         arrangement as provided in Section 12(d)(11)(A)
                         above, he shall be provided with the after-tax economic
                         equivalent of the benefits provided under the plan,
                         program or arrangement in which he is unable to
                         participate for the period specified in this Section
                         12(d)(11);

                    (Y)  the economic equivalent of any benefit foregone shall
                         be deemed to be the lowest cost that would be incurred
                         by the Executive in obtaining such benefit himself on
                         an individual basis; and

                    (Z)  payment of such after-tax economic equivalent shall be
                         made quarterly in advance; and

               (12) such other or additional benefits, if any, as are provided
                    under applicable plans, programs and/or arrangements of the
                    Company.

Notwithstanding anything contained herein to the contrary, the Board, in its
sole discretion, may accelerate the exercisability of some or all of such
unexercisable portion of Tranche 1, Tranche 2 and/or Tranche 3 on the date of
the termination of the Executive's employment or at any time during the
Severance Period.

(e)  TERMINATION OF EMPLOYMENT BY THE COMPANY WITHOUT CAUSE ON OR AFTER A
SECTION 2 NOTIFICATION DATE.  If, on or after a Section 2 Notification Date on
which the Company notifies the Executive that the Term of Employment will end in
accordance with Section 2 above, the Executive's employment is terminated by the
Company without Cause, other than due to death or Disability, the Term of
Employment shall end as of the date of the termination of the Executive's
employment and the Executive shall be entitled to the same payments and benefits
as provided in Section 12(d) above; PROVIDED, HOWEVER, that:

               (1)  for purposes of determining benefits and entitlements under
                    Sections 12 (d) (3) through 12 (d) (11) above, the Severance
                    Period shall begin on the date of the termination of the
                    Executive's employment and shall end on the 2nd anniversary
                    of the Section 2 Notification Date (the "Section 12 (e)
                    Severance Period"); and


<PAGE>

               (2)  for purposes of determining the Severance Benefit payable
                    under Section 12 (d) (3) above, the Severance Benefit as
                    determined in accordance with Section 12 (d) (3) above shall
                    be multiplied by a fraction the numerator of which shall be
                    the number of days in the Section 12 (e) Severance Period
                    and the denominator of which shall be 130, and such reduced
                    Severance Benefit shall be payable over the Section 22 (e)
                    Severance Period in equal installments in accordance with
                    the Company's regular payroll practice.

          (f}  TERMINATION OF EMPLOYMENT BY THE EXECUTIVE FOR GOOD REASON. The
Executive may terminate his employment for Good Reason at the end of the 60-day
period following the date that the Executive notifies the Company in writing in
accordance with Section 25 below that he intends to terminate his employment for
Good Reason (the "Notification Date"), such notice to state in detail the
particular event that constitutes Good Reason.  The Company shall have
reasonable opportunity to cure the event constituting Good Reason; PROVIDED,
HOWEVER, that if the Company has not cured such event to the reasonable
satisfaction of the Executive (and the Executive has not waived the Company's
failure to cure) during the 30-day period following the Notification Date (the
"Curing Period"), the Executive may terminate his employment following the end
of the Curing Period; PROVIDED, HOWEVER, that the Executive may not terminate
his employment for Good Reason after the end of the 90-day period following the
date the event constituting Good Reason first occurs.  Upon a termination by the
Executive of his employment for Good Reason, the Term of Employment shall end as
of the date of the termination of the Executive's employment and the Executive
shall be entitled to the same payments and benefits as provided in Section 12(d)
or 12(e) above, as applicable; PROVIDED, HOWEVER, that if the Executive
terminates his employment for Good Reason based on a reduction (i) in Base
Salary under Section (1)(i)(1) above and/or (ii) in his Target Award under
Section (1)(i) (2) above, then the Base Salary and/or the Target Award to be
used in determining the Severance Benefits in accordance with Section 12 (d) (3)
or 12 (e) (2) above shall be the Base Salary and/or the Target Award in effect
immediately prior to such reduction.

          (g)  VOLUNTARY TERMINATION OF EMPLOYMENT BY THE EXECUTIVE WITHOUT GOOD
REASON.  If the Executive voluntarily terminates his employment without Good
Reason, other than a termination of his employment due to death or Disability,
the Executive shall be entitled to the same payments and benefits as provided in
Section 12(c) above.  If the Executive notifies the Company in accordance with
Section 2 above that he wants the Term of Employment to end at the end of the
90-day period following such Section 2 Notification Date, and the Executive
terminates his employment as of the end of the Term of Employment, the
termination of the Executive's employment under this Section 12(g) shall not be
deemed a breach of this Agreement.

          (h)  REDUCTION OF PAYMENTS FOLLOWING A CHANGE IN CONTROL.
Notwithstanding anything contained herein to the contrary, if any amounts due to
the Executive under this Agreement and any other plan or program of the Company
constitute a "parachute payment" (as such term is defined in Code Section
280G(b) (2)), and the amount of the parachute payment, reduced by all federal,
state and local taxes applicable thereto, including the excise tax imposed
pursuant to Code Section 4999, is less than the amount the Executive would
receive if he were paid 3 times his "base amount" (as such term is defined in
Code Section 280G(b) (3)) less $1.00, reduced by all federal, state and local
taxes applicable thereto, then the aggregate of the amounts constituting the
parachute payment shall be reduced to an amount that will equal 3 times the
Executive's base amount less $1.00.  The determinations to be made


<PAGE>

with respect to this Section 12(h) shall be made by an accounting firm (the
Auditor") jointly selected by the Company and the Executive and paid by the
Company.  The Auditor shall be a nationally recognized United States public
accounting firm that has not during the two years preceding the date of its
selection acted, in any way, on behalf of the Company or any of its
subsidiaries.  If the Executive and the Company cannot agree on the firm to
serve as the Auditor, then each shall each select one such accounting firm and
those two firms shall jointly select such an accounting firm to serve as the
Auditor.  If a determination is made by the Auditor that a reduction in the
aggregate of all payments due to the Executive upon a Change in Control is
required by this Section 12 (h), the Executive shall have the right to specify
the portion of such reduction, if any, that will be made under this Agreement
and each plan or program of the Company.  If the Executive does not so specify
within 60 days following the date of a determination by the Auditor pursuant to
the preceding sentence, the Company shall determine, in its sole discretion, the
portion of such reduction, if any, to be made under this Agreement and each plan
or program of the Company.

          (i)  CONTINUED HEALTH-CARE COVERAGE TO AGE 65.  In the event of
any termination of the Executive's employment under Sections 12(b), 12(d), 12(e)
or 12 (f), the Executive shall be entitled to continued health-care coverage for
himself and his eligible dependents under the Company's "group health plan" (as
such term is defined in Code Section 4980B(g) (2)) as in effect from time to
time but subject to any limitations on coverage of nonemployees and their
dependents imposed under the terms of such group health plan or by any insurers
or partial insurers of such group health plan (other than such limitations
imposed unilaterally and in bad faith by the Company).  The Executive shall be
entitled to such health-care coverage until his 65th birthday; the Executive's
spouse shall be entitled to such health-care coverage until her 65th birthday;
and each of the Executive's eligible dependents shall be entitled to such
health-care coverage until his or her 21st birthday.  Unless the Company is
obligated to provide continued health-care coverage in accordance with Section
12(d) (11) above, the Executive shall pay to the Company on an annual basis in
advance the cost of such continued health-care coverage, with such cost to be
equal to the annual "applicable premium" (as such term is used under Code
Section 4980B (f) (4)) as determined in good faith by the Company.

          (j)  NO MITIGATION: NO OFFSET.  In the event of any termination of the
Executive's employment under this Section 12, the Executive shall be under no
obligation to seek other employment and there shall be no offset against amounts
due to the Executive under this Agreement on account of any remuneration
attributable to any subsequent employment that he may obtain except as
specifically provided in this Section 12.

    13.  CONFIDENTIALITY.

          (a)  CONFIDENTIAL INFORMATION.     The Executive acknowledges the
Company's exclusive ownership of all information useful in the business of the
Company, its subsidiaries and its affiliates (as used in this Section 13 and
Section 14 below, collectively, the "COMPANY") (including its dealings with
suppliers, customers and other third parties, whether or not a true "trade
secret"), which at the time or times concerned is not generally known to persons
engaged in businesses similar to those conducted by the Company, and which has
been or is from time to time disclosed to, discovered by, or otherwise known by
the Executive as a consequence of his employment by the Company (including
information conceived, discovered or developed by the Executive during his
employment with the Company) (collectively, "Confidential Information") .
Confidential Information includes, but is not limited to, the following
especially sensitive types of information:


<PAGE>

               (1)  the identity, purchase and payment patterns of, and special
                    relations with, the Company's customers;

               (2)  the identity, net prices and credit terms of, and special
                    relations with, the Company's suppliers;

               (3)  the Company's inventory selection and management techniques;

               (4)  the Company's product development and marketing plans; and

               (5)  the Company's finances, except to the extent publicly
                    disclosed.

          (b)  PROPRIETARY MATERIALS.  The term "Proprietary Materials"
shall mean all business records, documents, drawings, writings, software,
programs and other tangible things which were or are created or received by or
for the Company in furtherance of its business, including, but not limited to,
those which contain Confidential Information.  For example, Proprietary
Materials include, but are not limited to, the following especially sensitive
types of materials: applications software, the data bases of Confidential
Information maintained in connection with such software, and printouts generated
from such data bases; market studies and strategic plans; customer, supplier and
employee lists; contracts and correspondence with customers and suppliers;
documents evidencing transactions with customers and supplier; sales calls
reports, appointment books, calendars, expense statements and the like,
reflecting conversations with any company, customer or supplier; architectural
plans; and purchasing, sales and policy manuals.  Proprietary Materials also
include, but are not limited to, any such things which are created by the
Executive or with the Executive's assistance and all notes, memoranda and the
like prepared using the Proprietary Materials and/or Confidential Information.

          (c)  ACKNOWLEDGEMENTS BY EXECUTIVE.  While some of the information
contained in Proprietary Materials may have been known to the Executive prior to
employment with the Company, or may now or in the future be in the public
domain, the Executive acknowledges that the compilation of that information
contained in the Proprietary Materials has or will cost the Company a great
effort and expense, and affords persons to whom Proprietary Materials are
disclosed, including the Executive, a competitive advantage over persons who do
not know the information or have the compilation of the Proprietary Materials.
The Executive further acknowledges that Confidential Information and Proprietary
Materials include commercially valuable trade secrets and automatically become
the Company' 5 exclusive property when they are conceived, created or received.
The Executive shall report to the Company promptly, orally (or, at the Company's
request, in writing) all discoveries, inventions and improvements, whether or
not patentable, and which either (i) relate to or arise out of any part of the
Company's business in which the Executive participates, or (ii) incorporate or
make use of Confidential Information or Proprietary Materials (all items
referred to in this Section 13 being sometimes collectively referred to herein
as the "Intellectual Property").   All Intellectual Property shall be deemed
Confidential Information of the Company, and any writing or other tangible
things describing, referring to, or containing Intellectual Property shall be
deemed the Company's Proprietary Materials.  At the request of the Company,
during or after the Term of Employment, the Executive (or after the Executive's
death, the Executive's personal representative) shall, at the expense of the
Company, make, execute and deliver all papers, assignments, conveyances,
installments or other documents, and perform or cause to be performed such other
lawful acts, and give such testimony, as the Company deems necessary


<PAGE>

or desirable to protect the Company's ownership rights and Intellectual
Property.

          (d)  CONFIDENTIALITY DUTIES OF EXECUTIVE.  The Executive shall,
except as may be required by law, during the Term of Employment and during the
3-year period following the date of the termination of the Executive's
employment:

               (1)  comply with all of the Company's reasonable instructions
                    (whether oral or written) for preserving the confidentiality
                    of Confidential Information and Proprietary Materials;

               (2)  use Confidential Information and Proprietary Materials only
                    at places designated by the Company and in furtherance of
                    the Company's business;

               (3)  exercise appropriate care to advise other employees of the
                    Company (and, as appropriate, subcontractors) of the
                    sensitive nature of Confidential Information and Proprietary
                    Materials prior to their disclosure, and to disclose the
                    same only on a need-to-know basis;

               (4)  not copy all or any part of Proprietary Materials, other
                    than in the course of carrying out the Executive's duties
                    and responsibilities under this Agreement;

               (5)  not sell, give, loan or otherwise transfer any copy of all
                    or any part of Proprietary Materials to any person who is
                    not an employee of the Company, other than in the course of
                    carrying out the Executive's duties and responsibilities
                    under this Agreement;

               (6)  not publish, lecture on or otherwise disclose to any person
                    who is not an employee of the Company, other than in the
                    course of carrying out the Executive's duties and
                    responsibilities under this Agreement, all or any part of
                    Confidential Information or Proprietary Materials; and

               (7)  not use all or any part of any Confidential Information or
                    Proprietary Materials for the benefit of any third party
                    without the Company's written consent.

          (e)  RETURN OF COMPANY PROPERTY.  Upon the termination of the
Executive's employment under Section 12 above or upon the end of the Term of
Employment, the Executive (or in the event of death, the Executive's personal
representative) shall promptly surrender to the Company the original and all
copies of Proprietary Materials (including all notes, memoranda and the like
concerning or derived therefrom), whether prepared by the Executive or others,
which are then in the Executive's possession or control.  Records of payments
made by the Company to or for the benefit of the Executive, the Executive's copy
of this Agreement, his rolodexes, personal diaries, personal mementos, personal
effects shall not be deemed Proprietary Materials for purposes of this Section
13, and other such things, lawfully possessed by the Executive which relate
solely to taxes payable by the Executive, employee benefits due to the Executive
or the terms of the Executive's employment with the Company, shall also not be
deemed Proprietary Materials for purposes of this Section 13.

    14.  NONCOMPETITION; NONSOLICITATION.

         (a)  The Executive covenants and agrees that during the Term of
Employment and during the 2-year period following the end of the Term of
Employment, the Executive shall not, in any way, directly or indirectly, manage,
operate, control (or participate in any of the foregoing), accept employment or
a consulting position with or otherwise advise or assist or he connected with or
directly or indirectly own or have any other interest in or right with respect
to (other than through ownership of not more than 1 percent of the outstanding
shares of a corporation's stock which is listed on a national securities
exchange or the NASDAQ National Market) any enterprise (other than for the
Company or for the benefit of the Company) which is a wholesaler of office
products having annual sales in excess of $1,000,000.

         (b)  The Executive covenants and agrees that during the Term of
Employment and during the 2-year period following the end of the Term of
Employment, the Executive shall not at any time, directly or indirectly, solicit
(i) any client or customer of the Company or any of its subsidiaries with
respect to a competitive activity which violates Section 14 (a) above or (ii)
any employee of the Company or any of its subsidiaries for the purpose of
causing such employee to terminate his or her employment with the Company or
such subsidiary.

         (c)  If the Executive shall be in violation of any of the foregoing
restrictive covenants and if the Company seeks relief from such breach in any
court or other tribunal, such covenants shall be extended for a period of time
equal to the pendency of such proceedings, including all appeals.

         (d)  The Parties acknowledge that in the event of a breach or
threatened breach of Section 14(a) and/or Section 14 (b) above, the Company
shall not have an adequate remedy at law.  Accordingly, in the event of any
breach or threatened breach of Section 14 (a) and/or Section 14(b) above, the
Company shall be entitled to such equitable and injunctive relief as may be
available to restrain the Executive and any business, firm, partnership,
individual, corporation or entity participating in the breach or threatened
breach from the violation of the provisions of Section 14 (a) and/or Section
14(b) above.  Nothing in this Agreement shall be construed as prohibiting the
Company from pursuing any other remedies available at law or in equity for
breach or threatened breach of Section 14(a) and/or Section 14(b) above,
including the recovery of damages.

         (e)  The Executive recognizes, acknowledges and agrees that the
foregoing limitations are reasonable and properly required for the adequate
protection of the business of the Company.  If any such limitations are deemed
to be unreasonable by a court having jurisdiction of the matter and parties, the
Executive hereby agrees and submits to the reduction of any such limitations to
such territory or time as to such court shall appear reasonable.

assigned or transferred pursuant to a merger or consolidation in which the
Company is not the continuing entity, or the sale or liquidation of all or
substantially all of the assets of the Company; PROVIDED, HOWEVER, that the

condition or provision contained in this Agreement to be performed by such other
Party shall be deemed a waiver of a similar or dissimilar condition or provision

signed by the Executive or an authorized officer of the Company, as the case may
be.

withheld from such payments or by reason of any other payments made to or on
behalf of the Executive or for his benefit hereunder.

    20.  SEVERABILITY.

         In the event that any provision or portion of this Agreement shall be
determined to be invalid or unenforceable for any reason, in whole or in part,
the remaining provisions of this Agreement shall be unaffected thereby and shall
remain in full force and effect to the fullest extent permitted by law.

    21.  SURVIVORSHIP.

         The respective rights and obligations of the Parties hereunder shall
survive any termination of the Executive's employment to the extent necessary to
the intended preservation of such rights and obligations.
