ITEM 1.  BUSINESS
 
     Item 1. is presented with respect to both registrants submitting this
filing, DecisionOne Holdings Corp. and DecisionOne Corporation.
 
GENERAL
 
     DecisionOne Holdings Corp., through its wholly owned operating subsidiary
DecisionOne Corporation and its subsidiaries (collectively, the "Company") is
the largest independent provider of multivendor computer maintenance and
technology support services in the United States, based on Dataquest
Incorporated ("Dataquest") estimates for calendar year 1996. The Company offers
its customers a single source solution for virtually all of their computer
maintenance and technology support requirements, including hardware maintenance
services, software support, end-user/help desk services, network support and
other technology support services. The Company believes it is the most
comprehensive independent (i.e., not affiliated with an original equipment
manufacturer, or OEM) provider of these services across a broad range of
computing environments, including mainframes, midrange and distributed systems,
work groups, PCs and related peripherals. The Company provides support for over
15,000 hardware products manufactured by more than 1,000 OEMs. The Company also
supports most major operating systems and over 150 off-the-shelf software
applications. The Company delivers its services through an extensive field
service organization of approximately 4,000 field technicians in over 150
service locations throughout the United States and Canada and strategic
alliances in selected international markets.
 
     The Company services over 51,000 customers at over 182,000 sites across the
United States and Canada. The Company's customers include a diverse group of
national and multinational corporations, including SABRE Group, Inc. (an
affiliate of American Airlines, Inc.), Sun Microsystems, Inc. ("Sun"), Compaq
Computer Corporation ("Compaq"), NationsBank, DuPont Company ("DuPont"), Chevron
Corporation and Netscape Communications Corporation ("Netscape").
 
COMPANY HISTORY
 
     Founded in 1969, the Company began operations as a provider of key punch
machines under the tradename "Decision Data". During the 1980s, its operations
expanded to include the sale of midrange computer hardware and related
maintenance services. During fiscal 1993, the Company decided to focus
principally on providing computer maintenance and support services and sold its
computer hardware products business.
 
     From the beginning of fiscal 1993 through fiscal 1997, the Company has
established a major presence in the computer maintenance and technology support
services industry through the acquisition and integration of 36 complementary
businesses. The most significant of these were IDEA Servcom, Inc. ("Servcom"),
certain assets and liabilities of which were acquired in August 1994 for cash
consideration of $29.5 million; Bell Atlantic Business Systems Services, Inc.
("BABSS") which was acquired in October 1995 for approximately $250.0 million,
and certain assets of the U.S. computer service business of Memorex Telex
("Memorex Telex"), which were acquired in November 1996 for cash consideration
of approximately $24.4 million after certain purchase price adjustments.
 
     BABSS was established in the mid-1950s under the name Sorbus Inc. and was
acquired by Bell Atlantic Corporation in 1985. In January 1990, BABSS acquired
the assets of the third-party service business of Control Data Corporation
("CDC"), expanding its presence in the maintenance of large systems. After the
CDC acquisition, BABSS focused significant resources on the development of, and
experienced significant growth in, its customer and revenue bases, and by
mid-1995 had grown to be among the largest independent providers of multivendor
computer maintenance and technology support services in the United States.
 
     The BABSS acquisition provided the Company with a major presence in the
servicing of large mainframe systems and in other service areas, such as
software and network support, in which the Company had not
 
                                        1
<PAGE>   3
 
previously competed in a significant fashion. Moreover, the acquisition further
enhanced the Company's presence in its traditional midrange business. As a
result of the acquisition, BABSS became a wholly-owned subsidiary of the Company
and the name of the Company's principal operating subsidiary was changed to
DecisionOne Corporation.
 
MERGER AND RESTRUCTURING
 
     On August 7, 1997, the Company consummated a merger (the "Merger") with an
affiliate of DLJ Merchant Banking Partners II, L.P. ("DLJ"). Pursuant to the
Merger, DLJ, certain funds affiliated with DLJ (collectively, with DLJ, the "DLJ
Funds"), and third-party investors who have entered into an agreement (the
"Investors' Agreement") with DLJ in respect of the voting and disposition of
shares acquired by them (collectively, the "DLJ Group"), acquired approximately
10.9 million shares, or 87.4% of the Company's outstanding common stock in
exchange for approximately $225 million. Such equity proceeds, along with $145.5
million of net proceeds from the sale of 9 3/4% Senior Subordinated Notes due
2007 (the "9 3/4% Notes"), $81.6 million of net proceeds from the sale of units
consisting of 11 1/2% Senior Discount Debentures due 2008 and 148,400 Warrants
to purchase 281,960 shares of Company common stock exercisable at $23 per share
(the "Units"), and borrowings of $470.0 million under a $575 million senior
secured loan facility were used to repurchase approximately 26.5 million shares
for approximately $609.7 million, cash out existing options and warrants, repay
the Company's then-existing revolving credit facility, and pay fees and expenses
incurred in connection with the Merger. See "Merger and Recapitalization"
included in Item 7 herein.
 
INDUSTRY BACKGROUND
 
     The United States market for computer hardware maintenance and technology
support services is large and growing. According to Dataquest projections, the
hardware maintenance and technology support services market was approximately
$40.5 billion in 1996 and is projected to grow at a compound annual rate of 5.6%
to $50.3 billion by the year 2000. Within the market surveyed by Dataquest,
Dataquest estimates that the independent, multivendor segment was approximately
$8.8 billion in 1996 and projects the segment to grow at a 14% compound annual
rate to $14.8 billion by the year 2000. According to Dataquest, independent,
multivendor service providers such as the Company are taking market share from
the OEM service providers faster than OEMs are contracting new business. The
Company believes that this is occurring for several reasons including: (i)
customers are looking for single source providers who support multiple computer
hardware and software platforms, (ii) independent service providers are viewed
as being unbiased toward computer purchase decisions and (iii) OEMs are
increasingly outsourcing customer maintenance service (including warranty and
post warranty services) and technical customer support such as help desk
services to independents in order to focus on their core design, technology and
marketing competencies. According to Dataquest, within the independent,
multivendor segment, hardware maintenance was the dominant service, accounting
for approximately 71% of 1996 revenues, with technology support services,
including software support, network support and end-user training, comprising
the remaining 29% of 1996 revenues.
 
     The independent, multivendor segment is also fragmented and consolidating.
Participants in the independent multivendor segment include: (i) several large
independent service providers, (ii) the multivendor segments of OEM service
organizations and (iii) hundreds of smaller independent companies servicing
either product niches or limited geographical areas of the United States. The
significant market position of OEMs is due largely to their traditional role of
servicing their own installed base of equipment and their customers' former
reliance on centralized, single vendor solutions (i.e. mainframe systems).
 
COMPANY SERVICES
 
     The Company provides a comprehensive range of core technology support
services to customers across a broad range of computing environments, including
mainframes, midrange and distributed systems, work groups, PCs and related
peripherals. The Company customizes its service offerings to the individual
customer's needs in response to the nature of the customer's requirements, the
term of the contract and the combination of services that are provided. Services
are bundled to match the support requirements of
 
                                        2
<PAGE>   4
 
customers and include hardware support, end-user and software support, network
support, management information services, program management, planning support
and ancillary support services.
 
  Hardware Support
 
     Hardware support services consist of remedial and preventive maintenance
for computers and computer peripheral devices. The Company supports over 15,000
different hardware products manufactured by more than 1,000 OEMs. The Company's
customer support centers ("CSCs") handle over 330,000 calls per month regarding
hardware support. The Company maintains and manages an inventory of over 3.5
million parts representing more than 300,000 part numbers. The Company also has
access to a network of computer equipment vendors, brokers and highly skilled
repair suppliers, as well as access to certain IBM Designated Parts Sales
Locations.
 
     In addition to its on site diagnostic tools, the Company uses industry and
proprietary software diagnostic capabilities to monitor system performance on a
remote basis. Also, large customers are provided remote, on line access to
certain of the Company's systems to log service requests and track service
delivery.
 
     The Company prices its products and services on either a fixed fee or per
incident basis. Pricing is based on various factors including equipment failure
rates, cost of repairable parts and labor expenses.
 
  End-user and Software Support
 
     The Company's CSCs handle over 90,000 calls per month for help desk and
software support. Levels of support range from basic and network support for
corporate end-users to advanced operating system support for systems
administrators. Customized support also is available for vertical market
applications and OEM accounts. Operational services are available seven days per
week, twenty-four hours a day.
 
     The Company currently provides support for PC/workstation operating systems
such as Windows95(R), Windows(R), MS DOS(R), and Sun Microsystems' Solaris(R),
as well as support on network operating systems such as Novell Netware(R) and
Windows NT(R). Groupware products like Lotus Notes and Internet browsers such as
Netscape also are fully supported. Additionally, over 100 PC software products
ranging from spreadsheets and word processing to communications and graphics are
supported, as are numerous on-line services.
 
     The Company is a Microsoft Authorized Support Center, providing help desk
support for a broad range of Microsoft business software applications and
operating systems. Technical support is delivered through the Company's network
of CSCs and ranges from basic end-user software support to second level
professional support, and work in conjunction with Microsoft desktop
applications and operating systems, like Microsoft Windows(R)95 and
Windows(R)NT.
 
  Network Support
 
     The Company provides support services for networked computing environments,
including management, administration, and operations support for both local area
networks and wide area networks ("WANs"). Network support services are designed
to reduce the cost of ownership of networked computing, improve productivity of
network users, and supplement customers' internal support staffs. The Company's
remote network management services provide monitoring of fault and performance
data in customers' networks and problem resolution from the Company's network
management center. The Company also provides on site network services to assist
customers with network administration, operations, and remedial support. Network
specialists may be resident at the customer site or dispatched as necessary.
 
  Logistics Services
 
     The Company also repairs and refurbishes computer parts and assemblies at
seven depot repair centers in the United States. In addition to supporting its
own business, these services are provided primarily for OEMs, distributors and
other third party maintenance companies. Subassemblies repaired include system
logic boards, hard disk drive assemblies, peripherals, power supplies and
related equipment. The Company's depot
 
                                        3
<PAGE>   5
 
repair facilities located in Malvern, Pennsylvania; Boston, Massachusetts;
Milwaukee, Wisconsin; and San Francisco, California are certified to ISO-9002
standards.
 
     The Company also provides logistics services, including the planning and
forecasting of parts requirements and parts sourcing, inventory and warranty
management, for Compaq and other manufacturers. Under terms of the Compaq
logistics service contract, the Company handles orders from customers, dealers
and distributors in North America for parts that are no longer produced by
Compaq. The parts are used to repair Compaq desktops, laptops and servers and
include such components as flat panels (LCDs), motherboards, monitors, power
supplies and related parts. In addition to repair and replacement work, the
Company manages the program's logistics requirements and parts warranty
reimbursement activities.
 
  Program Management
 
     The Company provides ongoing management services for companies that wish to
outsource all or a portion of their services management requirements. Typical
services include third party vendor management, on site personnel support and
program evaluation, as well as a variety of support capabilities required to
prepare a system for operation and improve its efficiency. These support
capabilities include support for system installation, de-installation, moves,
upgrades, reconfigurations, system configuration audits, inventory tracking
services and data restoration assistance.
 
  Planning Support
 
     The Company assists customers in defining their enterprise service
requirements, establishing service delivery benchmarks, recommending process
improvements and auditing the results of implemented programs over time. The
objective of these consulting services is to assist customers in reducing the
total cost of ownership and improving operating efficiency in their service
environments.
 
  Information Services
 
     The Company makes service improvement recommendations to customers based on
information accumulated from its hardware, network and end-user support
services. Management information services allow customers to make informed
decisions relating to hardware and software procurements as well as the need for
increased employee training. The Company believes these services differentiate
it from OEMs and software developers that may favor their own products.
 
     The Company's AssetOne(TM) service tracks customers' desktop assets and
provides information on hardware configuration, software utilization, warranty
status, equipment location and user profiles. This information can then be used
to improve the way customers' assets are deployed, serviced, and used in order
to reduce costs and increase end-user productivity.
 
SUPPORT PARTNER PROGRAMS
 
     The Company maintains strategic alliances with several prominent companies
in order to provide customers with comprehensive technology support solutions.
The Company does not receive revenues for services provided by its strategic
partners. Key relationships include: General Electric Computer Leasing Corp.,
which provides computer acquisition, disposition and financing services; SunGard
Recovery Services Inc., which provides disaster recovery services; and MicroAge,
Inc., which supplies hardware products such as personal computers, peripherals,
network products and related devices.
 
SALES AND MARKETING
 
     The Company's core product capabilities are bundled to match the support
requirements of customers. Individual service portfolios exist for data center,
mid range and desktop environments. In addition, a product portfolio exists for
OEMs who seek support for parts sourcing and repair, inventory management and
related logistics services.
 
                                        4
<PAGE>   6
 
     The Company sells its services through both direct and indirect sales
channels. The Company's direct sales force consists of approximately 275 sales
professionals who are organized into a general commercial sales group as well as
into several dedicated groups including: a Federal Group, which sells to the
Federal Government; a National Accounts Group, which focuses on large and
multinational corporate customers; and a Telesales Group, which focuses on small
accounts.
 
     The Company also sells its services through its indirect sales force
comprised of approximately 25 sales professionals. Product support relationships
exist with OEMs such as Sequent Computer Corporation, EMC(2) Corporation
("EMC"), Sun and Compaq, and software developers such as Netscape, Novell, Inc.,
Microsoft Corporation and SunSoft, Inc.
 
INTERNATIONAL BUSINESS PARTNERS
 
     In order to provide international service to its multinational customers,
the Company supplements its broad North American infrastructure with strategic
alliances in selected international markets. The Company maintains relationships
with International Computers Limited ("ICL") and FBA Computer Technology
Services ("FBA"). The Company licenses many of its proprietary multivendor
support tools to FBA and to ICL Sorbus Ltd. ("ICL Sorbus"), which is ICL's
multivendor services group in Western Europe. As a result, the Company is able
to offer its multinational customers service in Western Europe, Asia and
Australia.
 
     ICL is a leading information technology company that has approximately
23,000 employees operating in about 80 countries around the world. In Western
Europe, the ICL Sorbus companies provide multivendor services in 17 countries
with approximately 250 service locations and about 5,000 employees. Several of
the Company's major customers, including SABRE Group, Inc. and DuPont, benefit
from the agreement between the Company and ICL Sorbus, whereby ICL Sorbus agrees
to provide services at the European locations of the Company's multinational
customers. Through ICL Sorbus, the Company utilizes the service branches of both
ICL and ICL's parent company, Fujitsu Ltd., to provide worldwide multivendor
support throughout Asia, the Pacific Rim, the Middle East and Africa.
 
     FBA, an affiliate of Fujitsu Ltd., provides multivendor services in
Australia and New Zealand from 21 locations with 150 employees. In addition to
providing technical support to FBA, the Company has supplied various management
and sales support personnel to FBA. FBA also provides services to certain of the
Company's multinational customers, including Sun.
 
SERVICE INFRASTRUCTURE
 
  Centralized Dispatch
 
     When a customer places a call for remedial maintenance, the Company uses
its Dispatch Data Gathering system ("DDG") to manage the process. When a
customer is identified, the DDG system displays the customer's service level
requirements and covered equipment. Specific information on the symptoms of the
problem and the products that are malfunctioning are entered into the system to
begin tracking the service event. The Company's Customer Support Representative
("CSR") selects, based upon the requirements of the service event, the
appropriate Customer Service Engineer ("CSE") from a list of pre-assigned
primary and back-up personnel and passes this information to the selected CSE.
 
     The Company maintains three CSCs in Malvern, Pennsylvania; Bloomington,
Minnesota; and Tulsa, Oklahoma. Customers can reach the CSCs by calling one toll
free telephone number. The CSCs currently are staffed with over 575 CSRs and 29
staff/operations managers. There is a duty manager on call in each center at all
times. CSCs are available on a 24 hour, 7 day per week basis. Redundancy for
disaster recovery purposes is designed into the CSC system through the three
locations' use of automatic telecommunications switching.
 
  Parts Logistics
 
     In order to meet customer computer repair requirements, the Company
maintains a tiered approach to management of its consumable and repairable spare
parts inventory. Parts or assemblies with low failure rates are stocked in
either the Company's central distribution center located in Malvern,
Pennsylvania or in its
 
                                        5
<PAGE>   7
 
critical parts center in Dallas, Texas. The Company also maintains six regional
distribution centers in Atlanta, Georgia; Newark, New Jersey; Los Angeles,
California; San Francisco, California; Chicago, Illinois; and Wilmington, Ohio
for critical parts needed more frequently throughout the United States. In order
to service customers whose response time requirements are two to four hours,
higher usage parts are maintained at the Company's branch offices or local
attended stocking locations. Customer site parts storage is arranged when
customer response time requirements are two hours or less.
 
     The Company's field inventory system ("FIS") is a real time system which
tracks the consumable and repairable parts assigned to its field workforce and
located at seven distribution centers, field offices or at customer sites. Parts
information processed through FIS is integrated with the Company's other key
systems, including DDG and International Support Information System ("ISIS").
 
  Service Technology
 
     The Company has developed several proprietary technologies for use in
service planning, support and delivery. These service tools include proprietary
databases, remote diagnostic and system monitoring software, and instructional
documentation. These technical support tools not only provide remote and on site
predictive and remedial service support, but also enable the Company to collect
extensive, objective systems performance measurement information (on the
customer's environment as well as benchmarking against the Company's database)
which its customers can use to identify potential efficiencies, evaluate
competing products and technologies, and determine whether its requirements are
being met.
 
     The Company's proprietary service technologies include ISIS, SERVICE EDGE
and MAXwatch(R). The Company licenses certain of these technologies and provides
other technical support to certain foreign multivendor service providers,
including ICL Sorbus in Europe, FBA in Australia and New Zealand, and PT
Metrodata Electronics in Indonesia.
 
     International Support Information Systems.  ISIS is a database accessible
to the Company's customer service engineers that is comprised of diagnostic and
symptom fix data for thousands of products, service updates, and service
planning information, such as machine performance and parts usage information,
and remote support capabilities for large IBM systems, including automatic "call
home" to the Company. The Company believes that ISIS is the most comprehensive
service related database of any independent computer service organization.
 
     SERVICE EDGE.  SERVICE EDGE is a PC based system installed at the
customer's site which monitors error messages and collects and reports service
data to help customers predict potential system failures and provide customers
with system performance information.
 
     MAXwatch(R).  MAXwatch(R) is an on-site program for products of Digital
Equipment Corporation ("Digital") which monitors system integrity, proactively
detects and corrects certain system errors, and automatically "calls home" for
remote technical support when pre defined error thresholds are exceeded. A

  Training
 
     The Company maintains the technical expertise of its engineers through
training programs designed to teach the various techniques for determining the
status of a customer's total computer operations. The Company's training offers
support professionals a broad exposure to various computer system technologies.
 
     The Company's training facilities include 26 classrooms, 23,000 square feet
of hands-on lab space, 26 full-time instructors and video specialists and a
curriculum of over 80 courses. The Company has five training centers and labs
located in Frazer, Pennsylvania; Malvern, Pennsylvania; Bloomington, Minnesota;
Milwau-
 
                                        6

kee, Wisconsin; and Phoenix, Arizona. Six months following course work, the
Company surveys the engineers to gauge the effectiveness and applicability of
its training curriculum.
 
CUSTOMERS
 
     The Company services over 51,000 customers at over 182,000 sites across the
United States and Canada. The Company sells services primarily to five types of
customers: large businesses that have complex computing support needs and
typically maintain a data center, distributed computing and work group
environments; medium sized businesses that rely primarily on distributed systems
for their computing needs; small businesses that principally use LANs and WANs
for computing; individuals who use stand alone computing systems; and OEMs and
software developers that contract with the Company for warranty services,
logistic support services or help desk support. A significant portion of the
Company's revenues are attributable to large businesses with complex computing
support needs.
 
COMPETITION
 
     Competition among computer support service providers, both OEM and
independent service organizations, is intense. The Company believes that
approximately 80% of that portion of the hardware maintenance services market
that is related to mainframes and stand alone midrange systems is currently
serviced by OEM service organizations. In addition, the Company believes that
OEM service organizations provide a smaller, but still significant, portion of
the computer maintenance services related to distributed systems, work groups
and PCs. The remainder of the market is serviced by a small number of larger,
independent companies, such as the Company, offering a broader range of service
capabilities, as well as numerous small companies focusing on narrower areas of
expertise.
 
     The Company considers its principal competitors to include: IBM and its
affiliate Technology Service Solutions, Digital, and Wang Laboratories, Inc.,
the multivendor service divisions of certain other OEMs, other national
independent service organizations that are not affiliated with OEMs such as
Vanstar Corporation, Entex Corporation and Stream International, Inc., and
various regional service providers.
 
     The Company believes that the primary competitive factors in the computer
services industry are the quality of a company's services, the ability to
service a wide range of products supplied by a variety of vendors, the
geographic coverage of a company's services and the cost to the customer of
those services. The Company believes that customers are increasingly looking for
service providers capable of providing a single source solution for their
increasingly complex multivendor systems. See "Risk Factors -- Competition;
Competitive Advantages of OEMs."
 
EMPLOYEES
 
     As of June 30, 1997, the Company had approximately 6,500 full-time and 60
part-time employees. None of the Company's employees is currently covered by
collective bargaining agreements. Management considers employee relations to be
good.

LOSS OF CONTRACT-BASED REVENUE; FIXED FEE CONTRACTS
 
     Over 85% of the Company's revenues during fiscal 1997 were contract based.
As is customary in the computer services industry, the Company experiences
reductions in its contract based revenue as customers may eliminate certain
equipment or services from coverage under the contracts, typically upon 30 days'
notice, or either cancel or elect not to renew their contracts upon 30, 60 or 90
days' notice. The Company believes the principal reasons for the loss of
contract based revenue are the replacement of the equipment being serviced with
new equipment covered under a manufacturer's warranty, the discontinuance of the
use of equipment being serviced for a customer due to obsolescence or a
customer's determination to utilize a competitor's services or to move technical
support services in house. While the Company historically has been able to
offset the reduction of contract based revenue and maintain revenue growth
through acquisitions and new contracts, notwithstanding the reduction in
contract based revenue, there can be no assurance it will continue to do so in
the future, and any failure to consummate acquisitions, enter into new contracts
or add additional services and equipment to existing contracts could have a
material adverse effect on the Company's profitability.
 
     Under many of the Company's contracts, the customer pays a fixed fee for
customized bundled services which are priced by the Company based on its best
estimates of various factors, including estimated future equipment failure
rates, cost of spare parts and labor expenses. While the Company believes it has
historically been able to estimate these factors accurately enough to be able to
price these fixed fee contracts on terms favorable to the Company, there can be
no assurance the Company will be able to continue to do so in the future.
 
SUBSTANTIAL LEVERAGE; STOCKHOLDERS' DEFICIT; LIQUIDITY
 
     In connection with the Merger, the Company entered into financings (the
"Merger Financing") including a new revolving credit facility (the "New Credit
Facility"), the terms of which include significant operating and financial
restrictions, such as limits on the Company's ability to incur indebtedness,
create liens,
 
                                        8
<PAGE>   10
 
sell assets, engage in mergers or consolidations, make investments and pay
dividends. In addition, the New Credit Facility requires the Company to maintain
certain debt to equity and other financial ratios.
 
     As of June 30, 1997, after giving pro forma effect to the Merger, including
the Merger Financing and the application of the proceeds thereof, the Company
would have had (i) total consolidated indebtedness of approximately $724.5
million and (ii) a stockholder's deficit of $243.1 million. In addition, subject
to the restrictions in the New Credit Facility and other agreements relating to
the Merger Financing, the Company may incur additional indebtedness from time to
time.
 
     The level of the Company's indebtedness could have important consequences
to the Company, including: (i) limiting cash flow available for general
corporate purposes, including acquisitions, because a substantial portion of the
Company's cash flow from operations must be dedicated to debt service; (ii)
limiting the Company's ability to obtain additional debt financing in the future
for working capital, repairable parts purchases, capital expenditures or
acquisitions; (iii) limiting the Company's flexibility in reacting to
competitive and other changes in the industry and economic conditions generally;
and (iv) exposing the Company to risks inherent in interest rate fluctuations
because certain of the Company's borrowings are at variable rates of interest,
which could result in higher interest expense in the event of increases in
interest rates.
 
     The Company's ability to make scheduled payments of principal of, to pay
interest on or to refinance its indebtedness and to satisfy its other debt
obligations will depend upon its future operating performance, which will be
affected by general economic, financial, competitive, legislative, regulatory,
business and other factors beyond its control. The Company anticipates that its
operating cash flow, together with borrowings under the New Credit Facility,
will be sufficient to meet its anticipated future operating expenses and capital
expenditures and to service its debt requirements as they become due. However,
if the Company's future operating cash flows are less than currently anticipated
it may be forced, in order to meet its debt service obligations, to reduce or
delay acquisitions, purchases of repairable parts or capital expenditures, sell
assets or reduce operating expenses, including, but not limited to, investment
spending such as selling and marketing expenses, expenditures on management
information on systems and expenditures on new products. If the Company were
unable to meet its debt service obligations, it could attempt to restructure or
refinance its indebtedness or to seek additional equity capital. There can be no
assurance that the Company will be able to effect any of the foregoing on
satisfactory terms, if at all. In addition, subject to the restrictions and
limitations contained in the agreements relating to the Merger Financing, the
Company may incur significant additional indebtedness to finance future
acquisitions, which could adversely affect the Company's operating cash flows
and its ability to service its indebtedness. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations: Liquidity and Capital
Resources."
 
MANAGEMENT AND FUNDING OF GROWTH
 
     Any future growth of the Company will require the Company to manage its
expanding domestic operations and international affiliations and to adapt its
operational and financial systems to respond to changes in its business
environment, while maintaining a competitive cost structure. The acquisition
strategy of the Company and the expansion of the Company's service offerings
have placed and will continue to place significant demands on the Company and
its management to improve the Company's operational, financial and management
information systems, to develop further the management skills of the Company's
managers and supervisors, and to continue to retain, train, motivate and
effectively manage the Company's employees. For example, the Company's
acquisition and integration of BABSS resulted in the loss of certain members of
its finance and accounting organization which resulted in a difficulty in the
timely performance of certain internal reconciliations and account analyses. In
response to these difficulties, the Company has taken various personnel and
procedural actions including, among other things, increasing the size of, and
restructuring its accounting staff, instituting an internal audit function and
enhancing its accounting systems, policies and procedures. The failure of the
Company to manage its prior or any future growth effectively could have a
material adverse effect on the Company.
 
                                        9
<PAGE>   11
 
     Additionally, the Company's ability to maintain and increase its revenue
base and to respond to shifts in customer demand and changes in industry trends
will be partially dependent on its ability to generate sufficient cash flow or
obtain sufficient capital for the purpose of, among other things, financing
acquisitions, satisfying customer contractual requirements and financing
infrastructure growth, including a significant investment in repairable parts,
which are classified as non current assets. There can be no assurance the
Company will be able to generate sufficient cash flow or that financing will be
available on acceptable terms (or permitted to be incurred under the terms of
the Merger Financing and any future indebtedness) to fund the Company's future
growth.
 
ACQUISITION GROWTH STRATEGY
 
     The Company has historically pursued an aggressive acquisition strategy,
acquiring certain contracts and assets in 36 transactions from the beginning of
fiscal 1993 through June 30, 1997. Future acquisitions and/or internal revenue
growth will be necessary to offset expected declines in contract based revenues.
As a result, the Company expects to continue to evaluate acquisitions that can
provide meaningful benefits by expanding the Company's existing and future
hardware maintenance and technology support capabilities and leveraging its
existing and future infrastructure. However, there are various risks associated
with pursuing an acquisition strategy of this nature. The risks include problems
inherent in integrating new businesses, including potential loss of customers
and key personnel and potential disruption of operations. There can be no
assurance that contracts acquired by the Company will generate significant
revenues or that customers covered by such acquired contracts will not choose to
terminate such contracts. The rate at which any such contracts are terminated
may be higher than the rates at which the Company's contracts have historically
been terminated. There also can be no assurance that suitable acquisition
candidates will be available, that acquisitions can be completed on reasonable
terms, that the Company will successfully integrate the operations of any
acquired entities or that the Company will have access to adequate funds to
effect any desired acquisitions. Future acquisitions may be limited by
restrictions in the Company's indebtedness.
 
COMPETITION; COMPETITIVE ADVANTAGES OF OEMS
 
     Competition among computer support service providers, both original
equipment manufacturer and independent service organizations, is intense. The
Company believes approximately 80% of that portion of industry hardware
maintenance services related to mainframes and stand alone midrange systems is
currently serviced by OEM service organizations. In addition, the Company
believes that OEM service organizations provide a smaller, but still
significant, portion of the computer maintenance services related to distributed
systems, work groups and PCs. The remainder of the market is serviced by a small
number of larger, independent companies, such as the Company, offering a broader
range of service capabilities, as well as numerous small companies focusing on
narrower areas of expertise or serving limited geographic areas.
 
     In many instances, OEM service organizations have greater resources than
the Company, and, because of their access to the OEM's engineering data, may be
able to respond more quickly to servicing equipment that incorporates new or
emerging technologies. Moreover, some OEMs, especially in the mainframe
environment, do not make available to end-users or independent service
organizations the technical information, repairable parts, diagnostics,
engineering changes and other support items required to service their products,
and design and sell their products in a manner so as to make it virtually
impossible for a third party to perform maintenance services without potentially
infringing upon certain proprietary rights of the OEM. In addition OEMs are
sometimes able to develop proprietary remote diagnostic or monitoring systems
which the Company may not be able to offer. Therefore, OEM service organizations
sometimes have a cost and timing advantage over the Company because the Company
must first develop or acquire from another party the required support items
before the Company can provide services for that equipment. An OEM's cost
advantage, the unavailability of required support items or various proprietary
rights of the OEM may preclude the Company from servicing certain products.
Furthermore, OEMs usually provide warranty coverage for new equipment for
specified periods, during which it is not economically feasible for the Company
to compete for the provision of maintenance services. To the extent OEMs choose,
for marketing reasons or otherwise, to expand their warranty periods or terms,
the Company's business may be adversely affected.
 
                                       10

     In June 1994, International Business Machines Corporation ("IBM") filed in
the United States District Court for the Southern District of New York (the
"Court") a motion to terminate a 1956 consent decree (the "IBM Consent Decree")
that, among other things, requires IBM to provide repairable parts,
documentation and other support items for IBM electronic data processing systems
to third parties on reasonable terms and places other restrictions on IBM's
conduct. On January 18, 1996, the Court entered an order approving a
modification of the IBM Consent Decree that, among other things, terminated the
IBM Consent Decree except insofar as it applies to the System 360/370/390
(mainframes) and AS/400 (midrange) families of IBM products. In July 1996, IBM
and the U.S. Department of Justice ("DOJ") reached an agreement in tentative
settlement of the remainder of IBM's motion and jointly moved to terminate on a
phased basis, the remaining provisions of the IBM Consent Decree (the "Joint
Motion"). On May 1, 1997 the Court granted the Joint Motion. Portions of the
order granting the Joint Motion have been appealed. Consequently, certain of the
remaining provisions of the IBM Consent Decree (primarily relating to sales and
marketing restrictions on IBM) terminate either immediately upon, or within six
months of, entry of the Court order; all of the other remaining provisions
(including those requiring IBM to provide parts and other support items to third
parties) terminate on July 2, 2000 with respect to AS/400 systems and on July 2,
2001 with respect to System 360/370/390 mainframes. The impact, if any, upon the
Company of the termination of such sales and marketing restrictions is
impossible to predict because it depends upon what changes, if any, IBM will
make in its sales and marketing policies and practices. As a result of the
termination of the IBM Consent Decree, the Company's ability to service midrange
and mainframe products may be adversely affected. Furthermore, as the Company's
business is highly dependent upon its ability to service a wide variety of
equipment in a multivendor environment, the inability to compete effectively for
the service of IBM mainframes and midrange products could cause the loss of a
substantial portion of the Company's customer base to IBM or an IBM affiliate,
which would have a material adverse effect on the Company's business.
 
CONSUMABLE AND REPAIRABLE PARTS MANAGEMENT
 
     In order to service its customers, the Company is required to maintain a
high level of consumable and repairable parts for extended periods of time. Any
decrease in the demand for the Company's maintenance services could result in a
substantial portion of the Company's consumable and repairable parts becoming
excess, obsolete or otherwise unusable. In addition, rapid changes in technology
could render significant portions of the Company's consumable and repairable
parts obsolete, thereby giving rise to write-offs and a reduction in
profitability. The inability of the Company to manage its consumable and
repairable parts or the need to write them off in the future could have a
material adverse effect on the Company's business, financial results and results
of operations.
 
     Consumable and repairable parts purchases are made from OEMs and other
vendors. The Company typically has more than a single source of supply for each
part and component, but from time to time it will have only a single supplier
for a particular part. In some cases, the Company's OEM customer may be the only
source of supply for a repair part or component. Should a supplier be unwilling
or unable to supply any part or component in a timely manner, the Company's
business could be adversely affected. In addition, the Company is dependent upon
IBM for obtaining certain parts that are critical to the maintenance of certain
IBM mainframe and midrange systems that IBM is currently required to make
available to third parties pursuant to the IBM Consent Decree. There can no
assurance that IBM will continue to make parts available for AS/400 Systems
after July 2, 2000 and for System 360/370/390 mainframes after July 2, 2001.
Even if such parts or components are available, a shortage of supply could
result in an increase in procurement costs which, if not passed on to the
customer, may adversely affect the Company's profitability.
 
COPYRIGHT ISSUES
 
     In connection with the Company's performance of most hardware maintenance,
the computer system which is being serviced must be turned on for the purpose of
service or repair. When the computer is turned on, the resident operating system
software and, in some cases diagnostic software, is transferred from a
peripheral storage device or a hard disk drive into the computer's random access
memory. Within the past several years, several OEMs have been involved in
litigation with independent service organizations, including
 
                                       11
<PAGE>   13
 
the Company, in which they have claimed such transfer constitutes the making of
an unauthorized "copy" of such software by the independent service organization
which infringes on the software copyrights held by the OEMs. The Company is
aware of three cases in this area which have been decided in favor of the OEM.
Although the Company was not a party in any of these cases, three similar claims
have been asserted against the Company, each of which has been resolved.
Litigation of this nature can be time consuming and expensive, and there can be
no assurance the Company will not be a party to similar litigation in the
future, or that such litigation would be resolved on terms that do not have a
material adverse effect on the Company.
 
DEPENDENCE ON COMPUTER INDUSTRY TRENDS; RISK OF TECHNOLOGICAL CHANGE
 
     The Company's future success is dependent upon the continuation of a number
of trends in the computer industry, including the migration by information
technology end-users to multivendor and multisystem computing environments, the
overall increase in the sophistication and interdependency of computing
technology, and a focus by information technology managers on cost efficient
management. The Company believes these trends have resulted in a movement by
both end-users and OEMs towards outsourcing and an increased demand for support
service providers that have the ability to provide a broad range of multivendor
support services. There can be no assurance these trends will continue into the
future.
 
     Additionally, rapid technological change and compressed product life cycles
are prevalent in the computer industry, which may lead to the development of
improved or lower cost technologies, higher quality hardware with significantly
reduced failure rates and maintenance needs, or customer decisions to replace
rather than continue to maintain aging hardware, and which could result in a
reduced need for the Company's services in the future. Moreover, such rapid
technological changes could adversely affect the Company's ability to predict
equipment failure rates, and, therefore, to establish prices that provide
adequate profitability. Similarly, new computer systems could be built based
upon proprietary, as opposed to open, systems that could not be serviced by the
Company.
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's continued success depends, to a large extent, upon the
efforts and abilities of key managerial employees, particularly the Company's
executive officers. There are not currently any employment contracts which would
ensure the continued employment of any executive officer. Competition for
qualified management personnel in the industry is intense. The loss of the
services of certain of these key employees or the failure to retain qualified
employees when needed could have a material adverse effect on the Company's
business. The Company does not currently maintain key man insurance.
 
CONTROL BY DLJ
 
     Approximately 87.4% of the outstanding shares of the Company's common stock
are currently held by the DLJ Group. As a result of its stock ownership and the
Investors' Agreement (which includes members of management to the extent their
shares are acquired through the Company's Direct Investment Program), the DLJ
Funds control the Company and have the power to elect a majority of the
Company's directors, appoint new management and approve any action requiring the
approval of the holders of the Company's common stock, including adoption of
certain amendments to the Company's certificate of incorporation and approving
mergers or sales of all or substantially all of the Company's assets. The
directors elected by the DLJ Funds have the authority to effect decisions
affecting the capital structure of the Company, including the issuance of
additional capital stock, the implementation of stock repurchase programs and
the declaration of dividends.
 
DILUTION
 
     The Company has granted approximately 1,179,000 options to purchase shares
of Company Common Stock to members of the Company's management, and may grant
additional options in the future. The aggregate number of shares of Company
Common Stock reserved for issuance pursuant to the Company's Management
Incentive Plan is 1,698,280, which includes approximately 251,000 shares to
accommodate options rolled over from the Company's previous stock option plan.
The exercise price of any options granted
 
                                       12
<PAGE>   14
 
pursuant to the Management Incentive Plan may be less than the fair market value
of the shares of Company Common Stock. Any such grant or exercise of any stock
option, will dilute the equity ownership percentage of Company stockholders and
the DLJMB Funds (and the Institutional Investors) and may result in a decrease
of the book value of the Company Common Stock per share. In addition, pursuant
to the Company's Direct Investment Program, certain members of management
purchased approximately 97,520 shares of Company Common Stock at the time of the
Merger. The aggregate number of shares reserved for issuance pursuant to the
Direct Investment Plan is 238,095. These purchases, and any future purchases
under the plan, would also dilute the equity ownership percentage of the DLJMB
Funds (and the Institutional Investors) and the Company stockholders.
 
POTENTIAL DELISTING AND LOSS OF LIQUIDITY
 
     As a result of the Merger, the Company's common stock no longer meets
certain maintenance requirements of The NASDAQ National Market System
("NASDAQ"). While NASDAQ has granted the Company a dispensation from such
maintenance requirements, there can be no assurance that in the future NASDAQ
will not unilaterally act to delist the Company's common stock. Following the
Merger, there has been a limited market for the Company's common stock because
of the significant ownership of the DLJ Group. In the event that a delisting
occurs stockholders may experience difficulty selling shares or obtaining prices
that reflect the value thereof.

ITEM 3.  LEGAL PROCEEDINGS
 
     Item 3 is presented with respect to both registrants submitting this
filing, DecisionOne Holdings Corp. and DecisionOne Corporation.
 
     The Company is a party, from time to time, to lawsuits arising in the
ordinary course of business. The Company believes it is not currently a party to
any material legal proceedings. However, within the past several years, several
OEMs have been involved in litigation with independent service organizations,
including
 
                                       13
<PAGE>   15
 
the Company, in which such OEMs have claimed infringement of software copyrights
held by the OEMs. The Company currently is not involved in any such litigation.
See "Risk Factors -- Copyright Issues."
 
     The Company, or certain businesses as to which it is alleged that the
Company is a successor, have been identified as potentially responsible parties
in respect of four waste disposal sites that have been identified by the United
States Environmental Protection Agency as Superfund Sites: (i) PAS Irwin Dump
Site, Oswego, New York (and six satellite sites, including the Fulton Terminals
Site, Fulton, New York); (ii) North Penn Area 6 Site, Lansdale, Pennsylvania;
(iii) Revere Chemical Site, Nockamixon, Pennsylvania; and (iv) Malvern TCE site,
Malvern, Pennsylvania. In addition, the Company received a notice several years
ago that it may be a potentially responsible party with respect to the Boarhead
Farms Site, Bridgeton, Pennsylvania, at a site related to the Revere Chemical
site, but has not received any additional communication with respect to that
site. Under applicable law, all parties responsible for disposal of hazardous
substances at those sites are jointly and severally liable for clean up costs.
The Company has estimated that its share of the costs of the clean up of one of
the sites will be approximately $500,000, which has been provided for in
liabilities related to the discontinued products division in the accompanying
consolidated balance sheets as of June 30, 1997, 1996 and 1995. Complete
information as to the scope of required clean up at these sites is not yet
available and, therefore, management's evaluation may be affected as further
information becomes available. However, in light of information currently
available to management, including information regarding assessments of the
sites to date and the nature of involvement of the Company's predecessor at the
sites, it is management's opinion that the Company's potential additional
liability, if any, for the cost of clean up of these sites will not be material
to the consolidated financial position, results of operations or liquidity of
the Company. See Note 16 to the Company's Consolidated Financial Statements.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.
 
     The following discussion should be read in conjunction with the Company's
Consolidated Financial Statements, DecisionOne Corporation and Subsidiaries'
Consolidated Financial Statements and the respective Notes thereto, as included
in Item 8 herein. Item 7 is presented with respect to both registrants
submitting this filing, DecisionOne Holdings Corp. and DecisionOne Corporation.
(As used in this Item 7, the term "Company" refers to DecisionOne Holdings Corp.
and its wholly-owned subsidiaries, including DecisionOne Corporation and the
term "Holdings" refers to DecisionOne Holdings Corp.)
 
     This discussion contains forward-looking statements within the meaning of
the Private Securities Litigation Reform Act of 1995 which involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed in "Risk
Factors" in Item 1.
 
COMPANY HISTORY
 
     Founded in 1969, the Company began operations as a provider of key punch
machines under the tradename "Decision Data." During the 1980s, its operations
expanded to include the sale of midrange computer hardware and related
maintenance services. During fiscal 1993, the Company decided to focus on
providing computer maintenance and support services and sold its computer
hardware products business.
 
                                       16
<PAGE>   18
 
     Since the beginning of fiscal 1993, the Company established a major
presence in the computer maintenance and technology support services industry
through the acquisition and integration of assets and contracts of 36
complementary businesses. Significant acquisitions included IDEA Servcom, Inc.
("Servcom"), certain assets and liabilities of which were acquired in August
1994 for cash consideration of approximately $29.5 million and BABSS, which was
acquired in October 1995 for cash consideration of approximately $250.0 million.
In addition, certain assets of the U.S. computer service business of Memorex
Telex were acquired in November 1996 for cash consideration of approximately
$24.4 million after certain purchase price adjustments. These acquisitions were
accounted for as purchase transactions.
 
     At the time of its acquisition by the Company, BABSS was among the largest
independent, multivendor service organizations servicing end-user organizations
and OEMs. Prior to the acquisition of BABSS, the Company had higher gross
margins than BABSS principally because approximately 30% of the Company's
revenues in fiscal 1995 were attributable to higher margin contracts involving
systems that can be serviced by a limited number of service providers
("proprietary systems"), whereas BABSS had limited revenues from proprietary
systems.
 
     The Company's primary source of revenues is contracted services for
multivendor computer maintenance and technology support services, including
hardware support, end-user and software support, network support and other
support services. Approximately 85% of the Company's revenues are derived from
maintenance contracts covering a broad spectrum of computer hardware. These
contracts typically have a stipulated monthly fee over a fixed initial term
(typically one year) and continue thereafter unless canceled by either party.
Such contracts generally provide that customers may eliminate certain equipment
and services from the contract upon notice to the Company. In addition, the
Company enters into per-incident arrangements with its customers. Per incident
contracts can cover a range of bundled services for computer maintenance or
support services or for a specific service, such as network support or equipment
relocation services. Another form of per incident service revenues includes time
and material billings for services as needed, principally maintenance and
repair, provided by the Company.
 
     Furthermore, the Company derives additional revenues from the repair of
hardware and components at the Company's logistics services and depot repair
facilities. Pricing of the Company's services is based on various factors
including equipment failure rates, cost of repairable parts and labor expenses.
The Company customizes its contracts to the individual customer based generally
on the nature of the customer's requirements, the term of the contract and the
services that are provided.
 
     The Company experiences reductions in revenue when customers replace
equipment being serviced with new equipment covered under a manufacturer's
warranty, discontinue the use of equipment being serviced due to obsolescence,
choose to use a competitor's services or move technical support services
in-house. The Company must more than offset this revenue "reduction" to grow its
revenues and seeks revenue growth from two principal sources: internally
generated sales from its direct and indirect sales force and the acquisition of
contracts and assets of other service providers. While the Company historically
has been able to offset the erosion of contract-based revenue and maintain
revenue growth through acquisitions and new contracts, notwithstanding the
reduction in contract based revenue, there can be no assurance it will continue
to do so in the future, and any failure to consummate acquisitions, enter into
new contracts or add additional services and equipment to existing contracts
could have a material adverse effect on the Company's profitability.
 
     Cost of revenues is comprised principally of personnel-related costs
(including fringe benefits), consumable parts cost recognition, amortization and
repair costs for repairable parts, and facilities costs and related expenses.
 
     The acquisition of contracts and assets has generally provided the Company
with an opportunity to realize economies of scale because the Company generally
does not increase its costs related to facilities, personnel and consumable and
repairable parts in the same proportion as increases in acquired revenues.

MERGER AND RECAPITALIZATION
 
     On August 7, 1997, the Company consummated the Merger with Quaker Holding
Co. ("Quaker"), an affiliate of DLJ Merchant Banking Partners II. The Merger,
which has been recorded as a recapitalization as of the consummation date for
accounting purposes, occurred pursuant to an Agreement and Plan of Merger among
the Company and Quaker dated May 4, 1997, as amended (the "Merger Agreement").
The respective Consolidated Financial Statements of DecisionOne Holdings Corp.
and DecisionOne Corporation and their respective subsidiaries as of and for the
year ended June 30, 1997, included herein, do not reflect transactions related
to the consummation of the merger.
 
     In accordance with the terms of the Merger Agreement, which was approved by
the Company's shareholders on August 7, 1997, Quaker merged with and into the
Company, and the holders of approximately 94.7% of shares of DecisionOne
Holdings Corp. common stock outstanding immediately prior to the Merger received
$23 in cash in exchange for these shares. Holders of approximately 5.3% of
shares of DecisionOne Holdings Corp. common stock outstanding immediately prior
to the Merger retained such shares in the merged Company, as determined based
upon shareholder elections and stock proration factors specified in the Merger
Agreement. The aggregate value of the Merger was approximately $940 million,
including refinancing of DecisionOne Corporation's revolving credit facility
(See Note 3 to the Company's Consolidated Financial Statements).
 
     As a result of the Merger, the Company incurred various expenses,
aggregating approximately $71 million on a pretax basis (approximately $64
million after related tax benefit), subject to adjustment, in connection with
consummating the transaction. These costs consisted primarily of compensation
costs, underwriting discounts and commissions, professional and advisory fees
and other expenses. The Company will report this one-time charge during the
first quarter of fiscal 1998. In addition to these expenses, the Company also
incurred approximately $22.3 million of capitalized debt issuance costs
associated with the Merger Financing. These costs will be charged to expense
over the terms of the related debt instruments (see "Liquidity and Capital
Resources").
 
     As a result of the foregoing, the Company expects to record a significant
net loss in the first quarter of fiscal 1998. Because this loss will result
directly from the one-time charge incurred in connection with the merger, and
this charge will be funded entirely through the proceeds of the Merger
Financing, the Company does not expect this loss to materially impact its
liquidity, ongoing operations or market position. For a discussion of the
consequences of the incurrence of indebtedness in connection with the Merger
Financing, see "Liquidity and Capital Resources."
 
RESULTS OF OPERATIONS
 
     The following discussion of results of operations is presented for the
fiscal years ended June 30, 1997, 1996 and 1995. The results of operations of
the Company include the operations of Memorex Telex from November 15, 1996,
BABSS from October 20, 1995 and Servcom from September 1, 1994.

(1) Adjusted EBITDA represents income (loss) from continuing operations before
    interest expense, interest income, income taxes, depreciation, amortization
    of intangibles, amortization of repairable parts, amortization of discounts
    and capitalized expenditures related to indebtedness, and non-recurring
    employee severance charges and provisions for unutilized leases. ("EBITDA"
    represents Adjusted EBITDA, increased by the amortization of repairable
    parts). Adjusted EBITDA is presented because it is relevant to certain
    covenants contained in debt agreements entered by the Company in connection
    with the merger, and because the Company believes that Adjusted EBITDA is a
    more-consistent indicator of the Company's ability to meet its debt service,
    capital expenditure and working capital requirements than EBITDA.

Overview
 
     The Company reported income from continuing operations before income taxes
of $53.1 million, $34.7 million, and $18.3 million in fiscal 1997, 1996 and 1995
respectively. Excluding pre-tax charges for employee severance and unutilized
lease costs in fiscal 1997 and 1996, income from continuing operations before
income taxes was $57.4 million and $38.4 million. Adjusted EBITDA was $109.1
million, $76.9 million, and $29.3 million in fiscal 1997, 1996 and 1995
respectively.
 
     Growth in Adjusted EBITDA and in income from continuing operations before
taxes in fiscal 1997 are primarily a result of certain strategic initiatives,
including the acquisition of complementary contracts and assets, enhancement of
the efficiency of the Company's field technician service force and renegotiation
of certain vendor contracts on more-favorable terms and related increases in
operating leverage.
 
  Fiscal 1997 Compared to Fiscal 1996
 
     Revenues:  Revenues increased by $245.8 million, or 45.5%, to $786.0
million for the fiscal year ended June 30, 1997 from $540.2 million for the
fiscal year ended June 30, 1996. This increase is attributable primarily to the
full period effect of the BABSS acquisition, which occurred on October 20, 1995.
To a lesser degree, this increase is attributable to the acquisition of the
service contracts of several complementary businesses, principally Memorex Telex
on November 15, 1996.
 
     Revenues for the quarter ended June 30, 1997 reflected strong growth in
per-incident and other non-contract revenues, compared to the previous quarter.
This revenue is subject to fluctuation depending upon customer demand for the
types and levels of such services. The Company currently expects a decline in
such revenues in the first quarter of fiscal 1998 compared to the fourth quarter
of fiscal 1997.
 
     Gross Profit:  Gross profit increased by $66.2 million, or 48.0%, from
$137.9 million for the fiscal year ended June 30, 1996 to $204.1 million for the
fiscal year ended June 30, 1997. This increase is due primarily to the
acquisition of BABSS in October, 1995, and to a lesser degree, the acquisition
of Memorex Telex in November, 1996.
 
     As a percentage of revenues, gross profit increased from 25.5% for the
fiscal year ended June 30, 1996 to 26.0% for the fiscal year ended June 30,
1997. This improvement in gross profit margin is primarily attributable to (i)
increased revenues, both from acquisitions during the fiscal year ended June 30,
1997 and internal sales growth without a proportionate increase in personnel and
other operating expenses, (ii) head count reductions in the Company's field
technician force effected in November 1996 and (iii) more efficient
 
                                       20
<PAGE>   22
 
utilization of the Company's field service personnel and resources to service
the increased revenues referred to above.
 
     Selling, General and Administrative Expenses:  Selling, general and
administrative expenses, exclusive of employee severance and unutilized lease
costs, increased by $39.4 million, or 56.9%, to $108.6 million for the fiscal
year ended June 30, 1997 from $69.2 million for the fiscal year ended June 30,
1996. This increase is primarily attributable to the full period effect in
fiscal 1997 of the BABSS acquisition, and to a lesser degree, to the acquisition
of Memorex Telex in fiscal 1996. As a percentage of revenues, exclusive of
employee severance and unutilized lease costs, selling, general and
administrative expenses increased to 13.8% for the fiscal year ended June 30,
1997 from 12.8% for the fiscal year ended June 30, 1996.
 
     Employee severance and unutilized lease costs:  During the fiscal year
ended June 30, 1997, the Company recorded $4.3 million in employee severance and
unutilized lease/contract costs, in connection with specific acquisitions. These
costs are included in Selling, general and administrative expenses in the
Company's Consolidated Statement of Operations. During fiscal 1996, the Company
recorded $3.6 million in employee severance and unutilized lease costs. These
costs were related principally to future rent obligations and related costs for
facilities of the Company that the Company determined were no longer required as
a result of the acquisition of BABSS. (See Note 15 to the Company's Consolidated
Financial Statements for additional information).
 
     Amortization of Intangibles:  Amortization of intangible assets increased
by $7.8 million, or 49.7%, from $15.7 million for the fiscal year ended June 30,
1996 to $23.5 million for the fiscal year ended June 30, 1997. This increase was
attributable principally to the amortization of intangibles resulting from the
BABSS and Memorex Telex acquisitions.
 
     Interest Expense:  Interest expense, net of interest income, equaled
approximately $14.7 million for each of the fiscal years ended June 30, 1997 and
1996. This was the result of two offsetting factors, as the Company's reduced
average borrowing rate on long-term indebtedness, (approximately 6.4% for the
fiscal year ended June 30, 1997 as compared to 9.0% for the fiscal year ended
June 30, 1996) substantially offset the increase in average borrowings during
the fiscal year ended June 30, 1997. The reduced average borrowing rate resulted
from the refinancing of the Company's revolving credit facility in April, 1996.
The increased average borrowings during fiscal 1997 were attributable primarily
to the funding requirements of several acquisitions, principally Memorex Telex.
 
     Income Taxes:  The Company's income tax provision for the fiscal year ended
June 30, 1997 reflects an estimated effective income tax rate of approximately
41%, while the effective income tax rate for the fiscal year ended June 30, 1996
was approximately 40%. This increase in the Company's anticipated effective
income tax rate was due primarily to the prior-year impact of certain
non-recurring foreign income tax benefits relating to net operating loss
carryforwards.
 
  Fiscal 1996 Compared to Fiscal 1995
 
     Revenues:  Revenues increased by $377.2 million, or 231.4%, from $163.0
million for the fiscal year ended June 30, 1995 to $540.2 million for the fiscal
year ended June 30, 1996. The increase is largely a result of acquisitions,
principally the BABSS acquisition in October 1995 which accounted for
approximately $350 million of the increase.
 
     Gross profit:  Gross profit increased by $88.4 million, or 178.6%, from
$49.5 million during the fiscal year ended June 30, 1995 to $137.9 million for
the fiscal year ended June 30, 1996. As a percentage of revenues, gross profit
decreased from 30.4% to 25.5%, reflecting the change in mix of services
resulting from the acquisition of BABSS. As a result of that acquisition, a
smaller portion of revenues was derived from proprietary systems which typically
generate higher profit margins than services for nonproprietary systems.
 
     Selling, general and administrative expenses:  Selling, general and
administrative expenses, exclusive of employee severance and unutilized lease
costs, increased by $47.2 million, from $22.0 million for the fiscal year ended
June 30, 1995 to $69.2 million for the fiscal year ended June 30, 1996,
principally as a result of the
 
                                       21
<PAGE>   23
 
additional expenses relating to the revenue growth discussed above. As a
percentage of revenues, selling, general and administrative decreased from 13.5%
to 12.8%, respectively, reflecting economies of scale.
 
     Employee severance and unutilized lease costs:  During fiscal 1996, the
Company recorded $3.6 million in employee severance and unutilized lease costs.
These costs were related principally to future rent obligations and related
costs for facilities of the Company that the Company determined were no longer
required as a result of the acquisition of BABSS. These costs are included in
Selling, general and administrative expenses in the Company's Consolidated
Statement of Operations. (See Note 15 to the Company's Consolidated Financial
Statements for additional information).
 
     Amortization and write-off of intangibles:  Amortization of intangibles
increased by $8.9 million, from $6.8 million for the fiscal year ended June 30,
1995 to $15.7 million for the fiscal year ended June 30, 1996, principally due
to the amortization of intangibles arising from the BABSS acquisition.
 
     Interest expense:  Interest expense increased by $12.2 million, from $2.5
million for the fiscal year ended June 30, 1995 to $14.7 million for the fiscal
year ended June 30, 1996, principally as a result of the indebtedness incurred
to finance the acquisition of BABSS. See Note 8 to the Company's Consolidated
Financial Statements.
 
     Provision for income taxes:  The income tax provision for the fiscal year
ended June 30, 1996 was based on an effective tax rate of approximately 40%. For
the fiscal year ended June 30, 1995, the Company reported an income tax benefit
equivalent of approximately 126%, arising primarily from the recognition of
future tax benefits of tax loss carry-forwards and temporary timing differences.
See Note 9 to the Company's Consolidated Financial Statements.
 
     Extraordinary item -- early extinguishment of debt:  Upon consummation of
its initial public offering in April 1996, the Company was required to pay the
total outstanding principal amount of its $30 million of 10.101% subordinated
debentures due October 20, 2001. This prepayment resulted in the write-off of
unamortized original issue discount of approximately $1.9 million, net of income
tax effect of $1.3 million, related to warrants issued with the debentures.
 
     Discontinued operations:  During fiscal 1995, the Company revised its
estimates of certain accruals created as a result of the disposal of its
computer products division during fiscal 1993. The reversal of certain accruals
resulted in $1.1 million in additional net income in fiscal 1995.
 
LIMITATION ON USE OF NET OPERATING LOSS CARRYFORWARDS AND OTHER TAX CREDITS
 
     As of June 30, 1997, the Company had tax loss carryforwards of
approximately $12.9 million and $8.7 million for Federal and state income tax
purposes, respectively, which are scheduled to expire between 1998 and 2008. The
Company also had minimum tax credits of approximately $1.5 million as of June
30, 1997, with no applicable expiration period. These carryforwards and credits
may be utilized, as applicable, to reduce future taxable income. The Company's
initial public offering in April, 1996 resulted in an "ownership change"
pursuant to Section 382 of the Code, which in turn resulted in the usage, for
U.S. federal income tax purposes, of these carryforwards and credits during any
future period being limited to approximately $20 million per annum.
 
     In addition, the Company's merger with Quaker in August, 1997 represents
another "ownership change" under Section 382 of the Code, and the Company,
therefore, estimates that, for U.S. federal income tax purposes, the limitation
on its use of tax loss carryforwards and other credits in any post-merger period
will be reduced to approximately $9.0 million per annum. The Company anticipates
that fees and expenses incurred in connection with the merger will result in
additional tax loss carryforwards arising in fiscal 1998. For financial
reporting purposes, the anticipated tax benefit associated with these
carryforwards will be limited due primarily to the length of the period during
which the anticipated tax benefit is expected to be realized. See Note 9 to the
Company's Consolidated Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES
 
  Post-Merger
 
     The Company's principal sources of liquidity will be cash flow from
operations and borrowings under its new $105 million revolving credit facility,
which was entered into in connection with the Merger. The Company's principal
uses of cash will be debt service requirements, capital expenditures, purchases
of repairable parts and acquisitions, and working capital. The Company expects
that ongoing requirements for debt service, capital expenditures, repairable
parts and working capital will be funded from operating cash flow and borrowing
under the new revolving credit facility. To finance future acquisitions, the
Company may require additional funding which may be provided in the form of
additional debt, equity financing or a combination thereof.
 
     The Company incurred substantial indebtedness in connection with the Merger
on August 7, 1997. On a pro forma basis, after giving effect to the Merger,
including the Merger financing and the application of the proceeds thereof, the
Company would have had approximately $724.5 million of indebtedness outstanding
as of June 30, 1997 as compared to actual $237.5 million of indebtedness
outstanding as of June 30, 1997. In addition, on the same pro forma basis, the
Company would have a stockholders' deficit of $243.1 million at June 30, 1997 as
compared to actual stockholders' equity of $214.9 million as of June 30, 1997.
The Company's significant debt service obligations following the Merger could,
under certain circumstances, have material consequences to security holders of
the Company. See "Risk Factors", included herein under Item 1.
 
     In connection with the Merger, Holdings issued $85 million of 11 1/2% Notes
due 2008 (the "11 1/2% Notes"). DecisionOne Corporation issued $150 million of
9 3/4% Notes due 2007 (the "9 3/4% Notes"). DecisionOne Corporation also entered
into a new syndicated credit facility providing for term loans of $470 million
and revolving loans of up to $105 million. The proceeds of the 11 1/2% Notes
(which were issued with attached warrants), 9 3/4% Notes, the initial borrowings
under the new credit facility and the purchase of approximately $225 million of
Holdings common stock by the DLJ Group have been used to finance the payments of
cash to cash-electing shareholders, to pay the holders of stock options and
stock warrants canceled or converted, as applicable, in connection with the
merger, to repay DecisionOne Corporation's existing revolving credit facility
and to pay expenses incurred in connection with the merger. See Note 3 to the
Company's and DecisionOne Corporation's Consolidated Financial Statements for
additional information.
 
     The Company has budgeted approximately $10 million in incremental
expenditures for information systems and related re-engineering initiatives to
be incurred in fiscal 1998. The initiatives to be funded include the following:
(i) enhancements to the Company's service entitlement process which will further
ensure that customers are billed for all work performed; (ii) improvements to
the Company's dispatch system and field engineer data collection and technical
support tools which are designed to increase productivity; (iii) enhancements to
the Company's help desk and central dispatch systems to provide an integrated
support solution to the customer base, and (iv) improvements to the Company's
field inventory tracking system which will facilitate increased transfer of
consumable and repairable parts among field locations and reduce purchases of
repairable parts. There can be no assurance that these amounts will be so
expended by the Company, nor when these amounts will be so expended. These
planned expenditures are expected to negatively impact income during fiscal year
1998.
 
     The Company anticipates that its operating cash flow, together with
borrowings under the new credit facility, will be sufficient to meet its
anticipated future operating expenses and capital expenditures and to service
its debt requirements as they become due. However, the Company's ability to make
scheduled payments of principal of, to pay interest on or to refinance its
indebtedness and to satisfy its other debt obligations will depend upon its
future operating performance, which will be affected by general economic,
financial, competitive, legislative, regulatory, business and other factors
beyond its control. See "Risk Factors", included herein under Item 1.

  Historical
 
     Financing:  Until its initial public offering in April 1996, the Company's
principal sources of capital had been borrowings from banks (primarily to
finance acquisitions), private placements of equity and debt securities with
principal stockholders and cash flow generated by operations. In April 1996, the
Company (i) completed an initial public offering, which raised approximately
$106 million and (ii) refinanced its bank debt, each of which is more fully
discussed below.
 
     The Company has relied on banks as the primary source of funds required for
larger acquisitions, such as the August 1994 acquisition of certain assets and
liabilities of Servcom and the October 1995 acquisition of BABSS. Since July
1993, the Company's smaller acquisitions have been funded primarily through a
combination of seller financing, cash and the assumption of liabilities under
acquired prepaid service contracts.
 
     In April 1996, the Company completed an initial public offering raising
$106 million through the issuance of 6.3 million shares of common stock. The
Company used the proceeds to repay approximately $70 million of its then
existing term loan (the "1995 Term Loan") and the Affiliate Notes. Concurrent
with the initial public offering, the Company's Preferred Stock (Series A, B and
C) was converted into common stock in accordance with the terms thereof.
 
     In April 1996, the Company converted the 1995 Term Loan and an existing $30
million revolving credit facility into a $225 million variable rate, unsecured
revolving credit facility (the "Facility"). During November 1996, in connection
with the acquisition of certain assets of the U.S. computer service business of
Memorex Telex, the Company's lender approved a $75 million increase to the
Facility, raising the total loan commitment to $300 million. See Note 8 to the
Company's Consolidated Financial Statements.
 
     The Facility provides for revolving borrowings up to $300 million. The
commitments thereunder terminate on April 26, 2001. The interest rate applicable
to the Facility varies, at the Company's option, based upon LIBOR (plus an
applicable margin not to exceed 1%) or the prime rate. The Company had entered
into interest rate swap agreements resulting in fixed Euro dollar interest rates
of 5.4% on $40.0 million through December 1997 and 5.5% on another $40.0 million
through December 1998. During fiscal 1997, the Company terminated these interest
rate swap agreements, resulting in an insignificant gain. See Notes 1 and 8 to
the Company's Consolidated Financial Statements.
 
     As of June 30, 1997, the interest rate applicable to loans under the
Facility was LIBOR plus .75%, or an effective rate of approximately 6.5%, and
available borrowings under the Facility were $65.7 million. Borrowings incurred
during fiscal 1997 included substantially all of the funding required with
respect to the Memorex Telex acquisition. See Note 4 to the Company's
Consolidated Financial Statements.
 
     The borrower under the Facility is DecisionOne Corporation, a wholly-owned
and the principal operating subsidiary of the Company. The obligations of
DecisionOne Corporation thereunder are guaranteed by the Company and certain
subsidiaries, except for its Canadian subsidiary. In connection with the merger
in August, 1997, all indebtedness outstanding under the Facility was repaid.
 
     Financial Condition:  Cash flow from operating activities for the fiscal
year ended June 30, 1997 was approximately $89.0 million. These funds, together
with borrowings under the Facility, provided the required capital to fund
repairable part purchases and capital expenditures of approximately $97.0
million, as well as the acquisition of contracts and assets of complementary
businesses for approximately $32.3 million.
 
     Reducing cash flow from operating activities for the fiscal year ended June
30, 1997 was a $1.8 million payment to the Internal Revenue Service in full
satisfaction of certain interest liabilities related to prior tax periods. See
Note 7 to the Company's Consolidated Financial Statements. The Company had
adequately accrued for this liability prior to payment, and no further amounts
are due with regard to these matters.
 
     In fiscal years 1996 and 1995, the Company generated net cash flow from
operating activities of $51.9 million and $38.4 million, respectively. Cash
required to fund the purchase of repairable parts and for capital expenditures
totaled $70.8 million and $14.9 million, during fiscal years 1996 and 1995,
respectively.
 
                                       24
<PAGE>   26
 
     The Company maintains a significant inventory of consumable and repairable
parts. Expendable parts are expensed as they are used in the operations of the
business. Repairable parts are recorded at cost at the time of their acquisition
and amortized over three to five years. The Company maintains a high level of
parts due to the wide range of products serviced, ranging from mainframe to
personal computers. At June 30, 1997, the Company had no material commitments
for purchases of spare parts or for other capital expenditures.
 
     The Company provides for obsolescence when accounting for consumable parts
and reviews obsolescence as it applies to its repairable parts. The Company
believes it has provided adequate reserves for obsolescence for consumable
parts. The Company believes that accumulated amortization on repairable parts
renders the need for an obsolescence reserve with respect to repairable parts
unnecessary.
 
     The most significant of the Company's acquisitions during the fiscal year
ended June 30, 1997 was the Memorex Telex acquisition on November 15, 1996. The
adjusted purchase price was $52.7 million, comprised of the Company's assumption
of $28.3 million of liabilities under acquired customer maintenance contracts,
and $24.4 million in cash, excluding transactions and closing costs, after
taking into account certain purchase price adjustments.
 
     The Company, or certain businesses as to which it is alleged that the
Company is a successor, have been identified as potentially responsible parties
in respect of four waste disposal sites that have been identified by the U.S.
Environmental Protection Agency as Superfund sites. In addition, the Company
received a notice several years ago that it may be a potentially responsible
party in respect of a fifth site, but has not received any other communication
in respect of that site. The Company has estimated that its share of the costs
of the cleanup of one of the sites will be approximately $500,000, which has
been provided for in liabilities related to the discontinued products division
in the Company's financial statements. Complete information as to the scope of
required cleanup at these sites is not yet available and, therefore,
management's evaluation may be affected as further information becomes
available. However, in light of information currently available to management,
including information regarding assessments of the sites to date and the nature
of involvement of the Company's predecessor at the sites, it is management's
opinion that the Company's potential additional liability, if any, for the cost
of cleanup of these sites will not be material to the consolidated financial
position, results of operations or liquidity of the Company. See Note 16 to the
Company's Consolidated Financial Statements.
 
EFFECT OF INFLATION; SEASONALITY
 
     Inflation has not been a material factor affecting the Company's business.
In recent years, the cost of electronic components has remained relatively
stable due to competitive pressures within the industry, which has enabled the
Company to contain its service costs. The Company's general operating expenses,
such as salaries, employee benefits, and facilities costs, are subject to normal
inflationary pressures.
 
     The operations of the Company are generally not subject to seasonal
fluctuations.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Shareholders
  of DecisionOne Holdings Corp.:
 
     We have audited the accompanying consolidated balance sheets of DecisionOne
Holdings Corp. and subsidiaries (the "Company") as of June 30, 1997 and 1996,
and the related consolidated statements of operations, shareholders' equity and
cash flows for each of the three years in the period ended June 30, 1997. Our
audits also included the financial statement schedules listed in the Index at
Item 14. These financial statements and financial statement schedules are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement schedules 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, such consolidated financial statements present fairly, in
all material respects, the financial position of DecisionOne Holdings Corp. and
subsidiaries as of June 30, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1997 in conformity with generally accepted accounting principles. Also, in our
opinion, the financial statement schedules, when considered in relation to the
basic consolidated financial statements taken as a whole, present fairly in all
material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                    YEARS ENDED JUNE 30, 1997, 1996 AND 1995
 
1.  NATURE OF BUSINESS
 
     DecisionOne Holdings Corp. and its wholly-owned subsidiaries (the
"Company") are providers of multivendor computer maintenance and technology
support services. The Company offers its customers a single-source, independent
(i.e., not affiliated with an original equipment manufacturer, or "OEM")
solution for computer maintenance and technology support requirements, including
hardware maintenance services, software support, end-user/help desk services,
network support and other technology support services. These services are
provided by the Company across a broad range of computing environments,
including mainframes, midrange and distributed systems, workgroups, personal
computers ("PCs") and related peripherals. In addition, the Company provides
outsourcing services for OEMs, software publishers, system integrators and other
independent service organizations. The Company delivers its services through an
extensive field service organization of approximately 4,000 field technicians in
over 150 service locations throughout North America and through strategic
alliances in selected international markets.
 
     Through June 30, 1995, the Company's services predominantly involved the
provision of maintenance services to the midrange computer market. On October
20, 1995, the Company acquired Bell Atlantic Business Systems Services, Inc.
("BABSS") (see Note 4). BABSS provided computer maintenance and technology
support services for computer systems ranging from the data center, which
includes both mainframe and midrange systems, to desk top. Subsequent to the
acquisition, the Company's principal operating subsidiary, Decision Servcom,
Inc., was merged into BABSS, which had changed its name to DecisionOne
Corporation. As a result, DecisionOne Corporation is the principal operating
subsidiary of the Company.
 
     The Company's wholly owned, direct international subsidiaries are not
significant to the Company's consolidated financial statements.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
     Consolidation -- The consolidated financial statements include the accounts
of DecisionOne Holdings Corp. and its wholly owned subsidiaries. All significant
intercompany balances and transactions have been eliminated in consolidation.
 
     Pro Forma Information (Unaudited) -- The pro forma information included in
the accompanying statement of operations and in Note 3 has been prepared to
reflect the Company's recapitalization and merger with Quaker Holding Co.
("Quaker") and related transactions as if these had occurred on July 1, 1996.
Historical earnings per share data for the fiscal years ended June 30, 1997,
1996 and 1995 is not presented as this would not be meaningful.
 
     Cash and Cash Equivalents -- Cash and cash equivalents are highly liquid
investments with remaining maturities of three months or less at the time of
purchase. Cash equivalents, consisting primarily of repurchase agreements with
banks, are stated at cost, which approximates fair market value.
 
     Consumable Parts and Repairable Parts -- In order to provide maintenance
and repair services to its customers, the Company is required to maintain
significant levels of computer parts. These parts are classified as consumable
parts or as repairable parts. Consumable parts, which are utilized during the
repair process, are stated at cost, principally determined using the weighted
average method, less an accumulated allowance for obsolescence and shrinkage.
Consumable parts are reflected in cost of revenues during the period utilized.
 
     Repairable (rotable) parts, which can be refurbished and reused, are stated
at original cost less accumulated amortization. Amortization of repairable parts
is reflected in cost of revenues. Costs of refurbishing repairable parts are
also included in cost of revenues as these costs are incurred. Amortization of
repairable parts is based principally on the composite group method, using
straight-line composite rates.
 
                                       F-7
<PAGE>   39
 
                  DECISIONONE HOLDINGS CORP. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Repairable parts generally have an economic life which corresponds to the normal
life cycle of the related products, currently estimated to be three to five
years.
 
     As consumable and repairable parts are retired, the weighted average gross
amounts at which such parts have been carried are removed from the respective
assets accounts, and charged to the accumulated allowance or accumulated
amortization accounts, as applicable. Periodic revisions to amortization and
allowance estimates are required, based upon the evaluation of several factors,
including changes in product life cycles, usage levels and technology changes.
Changes in these estimates are reflected on a prospective basis unless such
changes result from an extraordinary retirement or from other events or
circumstances which indicate that impairment may exist. Impairment is recognized
when the net carrying value of the parts exceeds the estimated current and
anticipated undiscounted net cash flows. Measurement of the amount of
impairment, if any, is calculated based upon the difference between carrying
value and fair value.
 
     Property and Equipment -- Property and equipment are stated at cost.
Depreciation is provided for using the straight-line method over the estimated
useful lives of the depreciable assets. Capitalized equipment leases and
leasehold improvements are amortized over the shorter of the related lease terms
or asset lives. Maintenance and repairs are charged to expense as incurred. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is charged to operations.
 
     Business and Contract Acquisitions -- Business and contract acquisitions
have been accounted for as purchase transactions, with the purchase price of
each acquisition allocated to the assets acquired and liabilities assumed based
upon their respective estimated fair values at the dates of acquisition.
Consistent with the Company's parts retirement accounting methods, the gross
value of parts acquired is generally stated at weighted average cost. Fair value
adjustments, if any, are reflected as adjustments to the respective accumulated
amortization or allowance accounts. The excess of the purchase price over
identified net assets acquired is amortized, on a straight-line basis, over the
expected period of future benefit (see Note 6).
 
     Typical contract acquisitions are comprised primarily of customer
maintenance and support contracts of complementary entities, along with the
accompanying consumable and repairable parts required to support these contracts
and other identifiable intangibles, such as noncompete agreements. Liabilities
assumed in business and contract acquisitions consist primarily of prepaid
amounts related to multi-period customer maintenance and support contracts.
These liabilities are recorded as deferred revenues at acquisition dates and are
recognized as revenues when earned in accordance with the terms of the
respective contracts.
 
     Intangible Assets -- Intangible assets are comprised of excess purchase
price over the fair value of net assets acquired, acquired customer lists and
other intangible assets, including the fair value of contractual profit
participation rights and amounts assigned to noncompete agreements.
 
     Intangible assets, which arise principally from acquisitions, are generally
amortized on a straight-line basis over their respective estimated useful lives
(see Note 6). The Company evaluates the carrying value of intangible assets
whenever events or changes in circumstances indicate that these carrying values
may not be recoverable within the amortization period. Impairment is recognized
when the net carrying value of the intangible asset exceeds the estimated
current and anticipated discounted future net cash flows. Measurement of the
amount of impairment, if any, is calculated based upon the difference between
carrying value and fair value.
 
     Revenue -- The Company enters into maintenance contracts whereby it
services various manufacturers' equipment. Revenues from these contracts are
recognized ratably over the terms of such contracts. Prepaid revenues from
multi-period contracts are recorded as deferred revenues and are recognized
ratably over the term of the contracts.

                  DECISIONONE HOLDINGS CORP. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Revenues derived from the maintenance of equipment not under contract are
recognized as the service is performed. Revenues derived from other technology
support services are recognized as the service is performed or ratably over the
term of the contract.
 
     Foreign Currency Translation -- Gains and losses resulting from foreign
currency translation are accumulated as a separate component of shareholders'
equity. Gains and losses resulting from foreign currency transactions are
included in operations.
 
     Credit Risk -- Concentration of credit risk with respect to trade
receivables is limited due to the large number of customers comprising the
Company's customer base and their dispersion across many industries.
 
     Fair Value of Financial Instruments -- The following disclosures of the
estimated fair value of financial instruments were made in accordance with the
requirements of SFAS No. 107, Disclosures about Fair Value of Financial
Instruments. The estimated fair value amounts have been determined by the
Company using available market information and appropriate valuation
methodologies.
 
          Cash and Cash Equivalents, Accounts Receivable, and Accounts
     Payable -- The carrying amount of these items are a reasonable estimate of
     their fair value.
 
          Short-Term Debt and Long-Term Debt -- As more fully described in Note
     8, under its revolving borrowing facility the Company incurs interest at
     variable rates based upon market conditions (i.e., based upon the prime
     rate or LIBOR). Rates applicable to other debt instruments, which consist
     primarily of short-term notes payable in connection with certain
     acquisitions, are comparable to those of similar instruments currently
     available to the Company. Accordingly, the carrying amount of debt is a
     reasonable estimate of its fair value.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results may differ from those estimates and
assumptions.
 
     Discontinued Operations -- During fiscal 1993, in connection with the sale
of its products division, the Company established estimated liabilities relating
to the settlement of the remaining assets and liabilities of this division. In
1995, the Company revised its estimates as a result of settlement of these
liabilities, and the consolidated statement of operations for 1995 reflects an
increase in net income of $1,113,000 for the change in estimate.
 
     Stock-Based Compensation -- Effective July 1, 1996, the Company adopted the
provisions of SFAS No. 123, Accounting for Stock-Based Compensation. SFAS No.
123 encourages, but does not require, companies to record compensation cost for
stock-based compensation plans at fair value. The Company has elected to
continue to account for stock-based compensation in accordance with Accounting
Principles Board ("APB") Opinion No. 25, Accounting for Stock Issued to
Employees, and related interpretations, as permitted by SFAS 123. Compensation
expense for stock options is measured as the excess, if any, of the quoted
market price of the Company's stock at the date of the grant over the amount an
employee must pay to acquire the stock (see Note 11).
 
     Derivative Financial Instruments -- Derivative financial instruments, which
constitute interest rate swap agreements (see Note 8), are periodically used by
the Company in the management of its variable interest rate exposure. Amounts to
be paid or received under interest rate swap agreements are recognized as
interest expense or interest income during the period in which these accrue.
Gains realized, if any, on the early termination of interest rate swap contracts
are deferred, to be recognized upon the termination of the related asset or
liability or expiration of the original term of the swap contract, whichever is
earlier. The Company does not hold any derivative financial instruments for
trading purposes.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Recent Accounting Pronouncement -- In February 1997, the Financial
Accounting Standards Board issued SFAS No. 128, Earnings Per Share. SFAS No.
128, which supersedes APB No. 15, Earnings Per Share, requires a dual
presentation of basic and diluted earnings per share as well as disclosures
including a reconciliation of the computation of basic earnings per share to
diluted earnings per share. Basic earnings per share excludes the dilutive
impact of common stock equivalents and is computed by dividing net income by the
weighted average number of shares of common stock outstanding for the period.
Diluted earnings per share, which will approximate the Company's currently
reported pro forma earnings (loss) per share, includes the effect of potential
dilution from the exercise of outstanding common stock equivalents into common
stock, using the treasury stock method at the average market price of the
Company's common stock for the period.
 
     SFAS No. 128 is effective for interim and annual financial reporting
periods ending after December 15, 1997, and early adoption is not permitted.
When adopted by the Company, as required, for the fiscal quarter ending December
31, 1997, all prior quarters' earnings (loss) per share information will be
required to be restated on a comparable basis.
 
     Assuming that SFAS No. 128 had been implemented, supplemental pro forma
basic loss per share and supplemental pro forma diluted loss per share would not
have differed from the pro forma loss per share presented in the accompanying
consolidated statements of operations for the fiscal year ended June 30, 1997.
 
     Reclassifications -- Certain reclassifications have been made to the 1996
balances in order to conform with the 1997 presentation.
 
3.  MERGER, RECAPITALIZATION AND PRO FORMA INFORMATION
 
     On August 7, 1997, the Company consummated a merger with Quaker Holding Co.
("Quaker"), an affiliate of DLJ Merchant Banking Partners II. The merger, which
will be recorded as a recapitalization for accounting purposes as of the
consummation date, occurred pursuant to an Agreement and Plan of Merger (the
"Merger Agreement") between the Company and Quaker dated May 4, 1997. The
accompanying historical consolidated financial statements do not include any
adjustments with respect to the consummation of the merger.
 
     In accordance with the terms of the Merger Agreement, which was formally
approved by the Company's shareholders on August 7, 1997, Quaker merged with and
into the Company, and the holders of approximately 94.7% of shares of Company
common stock outstanding immediately prior to the merger received $23 in cash in
exchange for each of these shares. Holders of approximately 5.3% of shares of
Company common stock outstanding immediately prior to the merger retained such
shares in the merged Company, as determined based upon shareholder elections and
stock proration factors specified in the Merger Agreement. Immediately following
the merger, continuing shareholders owned approximately 11.9% of shares of
outstanding Company common stock. The aggregate value of the merger transaction
was approximately $940 million, including refinancing of the Company's revolving
credit facility (see Note 8).
 
     In connection with the merger, the Company raised $85 million through the
public issuance of discount debentures, in addition to publicly-issued
subordinated notes for approximately $150 million. The Company also entered into
a new syndicated credit facility providing for term loans of $470 million and
revolving loans of up to $105 million. The proceeds of the discount notes,
subordinated notes, the initial borrowings under the new credit facility and the
purchase of approximately $225 million of Company common stock by Quaker have
been used to finance the payments of cash to cash-electing shareholders, to pay
the holders of stock options and stock warrants canceled or converted, as
applicable, in connection with the merger, to repay the Company's existing
revolving credit facility and to pay expenses incurred in connection with the
merger.
 
     As a result of the merger, the Company incurred various expenses,
aggregating approximately $71 million on a pretax basis (approximately $64
million after related tax benefit), subject to adjustment, in connection with
consummating the transaction. These costs consisted primarily of compensation
costs, underwriting

discounts and commissions, professional and advisory fees and other expenses.
The Company will report this one-time charge during the first quarter of fiscal
1998. In addition to these expenses, the Company also incurred approximately
$22.3 million of capitalized debt issuance costs associated with the merger
financing. These costs will be charged to expense over the terms of the related
debt instruments.
 
     The following summarized unaudited pro forma information as of and for the
year ended June 30, 1997 assumes that the merger had occurred on July 1, 1996.
The pro forma results have been prepared for comparative purposes only and do
not purport to be indicative of the financial condition or of the results of
operations which actually would have resulted had the merger occurred as of July
1, 1996 or which may result in the future.

attributable to additional financing incurred in connection with the merger, net
of repayment of the Company's existing revolving credit facility. Pro forma
weighted average common and common equivalent shares outstanding include
12,499,978 shares outstanding immediately subsequent to the merger on August 7,
1997 and dilutive common stock warrants and stock options (convertible into
281,960 and 1,418,530 shares of common stock, respectively) issued in connection
with or immediately subsequent to the merger.

     On August 31, 1994, the Company purchased certain net assets and
liabilities of IDEA/Servcom, Inc. for approximately $29,500,000. This
acquisition was funded by cash and the issuance of a $2,600,000 noninterest-
bearing note to the seller. See seller notes payable section of Note 8. The
excess of asset purchase price over the fair value of net assets acquired at the
date of purchase was approximately $7,400,000.
 
     On October 20, 1995, the Company acquired all of the outstanding common
stock of BABSS, a subsidiary of Bell Atlantic Corporation ("BAC") for
approximately $250,549,000. The acquisition was funded with the proceeds from
the issuance of $30,000,000 of Series C preferred stock, $30,000,000 of
subordinated debentures and the balance from additional bank borrowings (see
Notes 8 and 13). The excess of asset purchase price over the fair value of net
assets acquired at the date of purchase was initially recorded as approximately
$58,796,000. Subsequent to the acquisition, the Company recorded a net
adjustment increasing the initial amount by $1,737,000 and adjusted other
balance sheet accounts principally by the same amount. This resulted from the
adjustment and reclassification of certain tax accruals offset by favorable
negotiations on certain leased facilities (see Note 7). As part of the
acquisition, the Company purchased from BAC contractual profit participation
rights whereby the Company will receive a fixed percentage of the annual
operating profits (3.2% or 3.5%, depending upon the level of profits) earned by
a former foreign affiliate of BAC which provides computer maintenance and
technology support services in Europe. The estimated value of the discounted
estimated future cash flows over a twenty-year period from the acquisition date
from these contractual profit participation rights is $25,000,000.
 
     Included in nonsignificant maintenance contract acquisitions is the
acquisition of substantially all of the contracts and related assets, including
spare parts of the U.S. computer service business of Memorex Telex Corporation
and certain of its affiliates (collectively, "Memorex Telex"). Memorex Telex had
filed a petition in bankruptcy in the United States Bankruptcy Court (the
"Court") in the District of Delaware on October 15, 1996; the Court approved the
sale to the Company on November 1, 1996. The adjusted purchase price was $52.7
million, comprised of the assumption of certain liabilities under contracts of
the service business, which were valued at $28.3 million, and base cash
consideration of approximately $24.4 million, after certain purchase price
adjustments, excluding transaction and closing costs.
 
     The estimated fair market values of certain assets acquired, as well as
liabilities assumed, are subject to further adjustment as additional information
becomes available to the Company. During the third quarter of fiscal 1997, the
Company recorded an adjustment increasing the deferred revenues assumed in the
Memorex Telex acquisition by approximately $2,300,000, to revise the estimated
fair value of certain contract liabilities of the business assumed by the
Company.
 
     The following summarized unaudited pro forma information for significant
acquisitions that have a material effect on the Company's results of operations
for the years ended June 30, 1996 and 1995 assumes that the acquisitions
occurred as of July 1, 1994. The nonsignificant business and maintenance
contract acquisitions are not considered material individually or in the
aggregate. The pro forma results have been prepared for comparative purposes
only and do not purport to be indicative of the results of operations which
actually would have resulted had the significant acquisitions been in effect on
the dates indicated or which may result in the future.

     Prior to 1994, the Company received $2,600,000 in tax bills (primarily
interest) from the Internal Revenue Service ("IRS") related to claims for tax
and interest for the years 1981 through 1987. The Company paid approximately
$500,000 of the claims upon receipt of the bills. Although the Company disputed
the tax bills, an IRS mandated payment of $828,000 was made in 1996. As of June
30, 1996, the Company had an accrued liability of $1,883,000 related to this
assessment. During fiscal 1997, the Company paid $1,729,000 in full settlement
of these tax and interest bills.
 
     In connection with the acquisition of BABSS, which has been accounted for
using the purchase method of accounting (see Note 4), the Company recorded
approximately $11,000,000 in liabilities resulting from planned actions with
respect to BABSS, which included the costs to exit certain leased facilities and
to involuntarily terminate employees. The provision of approximately $3,500,000
for the costs to exit certain leased facilities principally relates to future
lease payments on a warehouse in California which has been made idle.
Approximately $4,000,000 was provided for severance and termination benefits of
approximately 210 employees in the field, operations support, sales and
administration. Approximately $3,000,000 was provided in connection with the
exit plan for write-downs of spare parts and equipment at two California
facilities which will not be utilized in future operations. The provision for
various other charges of approximately $500,000 consisted of costs to complete
the exit plan. As of June 30, 1996, the Company had settled all of these
liabilities, except for the lease liabilities on idle facilities for which
payments were scheduled to continue through 1999 (see Note 15). At June 30, 1997
and 1996 remaining amounts due under these leases were $0 and $1,200,000,
respectively.
 
     As a result of successful negotiations of unutilized leased facilities,
during 1996, the Company recorded a reduction of approximately $975,000 to both
the provisions for leased facilities and excess purchase price over fair value
of net assets acquired.

REVOLVING CREDIT LOANS
 
     On October 20, 1995, in connection with the BABSS acquisition (see Note 4)
the Company entered into a Credit Agreement which provided for a term loan (the
"1995 Term Loan") of $230,000,000 and a revolving credit facility of up to a
maximum of $30,000,000. The 1995 Term Loan provided for 19 equal quarterly
principal payments of $10,000,000 to be due and payable on the last day of each
calendar quarter commencing December 31, 1995 with a final payment due on
September 30, 2000. Loans under the revolving credit facility were to mature on
September 30, 2000. Interest on the 1995 Term Loan and the revolving credit
facility were at varying rates based, at the Company's option, on the Eurodollar
rate or the Alternative Base Rate (NationsBanc prime rate), plus the Applicable
Margins. Margins were based on the ratio of Total Funded Debt to EBITDA; the
Eurodollar Margin ranged from 1.75% to 2.5%, while the Alternative Base Rate
Margin ranged from 0.5% to 1.25%.
 
     In April 1996, the Company completed an initial public offering (see Note
13). The Company used a portion of the proceeds to repay approximately $70
million of the 1995 Term Loan.
 
     Also in April 1996, the Company converted the 1995 Term Loan and the
existing $30 million Revolving Credit Facility into a $225 million variable
rate, unsecured revolving credit facility ("the 1996 Revolving Credit
Facility"). During fiscal 1997, the 1996 Revolving Credit Facility commitment
was increased to $300 million, in connection with the acquisition of certain
contracts and assets. The 1996 Revolving Credit Facility is at floating interest
rates, based either on the LIBOR or prime rate, in either case plus an
Applicable Margin, at the Company's option. As of June 30, 1997, the applicable
rate was LIBOR plus .75% or approximately 6.5%. The 1996 Revolving Credit
Facility enables the Company to borrow up to $300 million in the form of
revolving credit loans with a maturity date of April 26, 2001 and with interest
periods determined principally on a quarterly basis. To offset the variable rate
characteristics of the borrowings, the Company entered into interest rate swap
agreements with two banks resulting in fixed interest rates of 5.4% on $40.0
million notional principal amount through December 1997 and 5.5% on another
$40.0 million notional principal amount through December 1998.
 
     During fiscal 1997, the Company terminated these swap agreements, resulting
in an insignificant gain which has been deferred to the first quarter of fiscal
1998.
 
     Under the terms of the 1996 Revolving Credit Facility, the Company may use
up to $25,000,000 for letters of credit, subject to the limitation of
$300,000,000 in total credit. As of June 30, 1997, letters of credit in the face
amount of $3,067,000 were outstanding.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The loan agreement relating to the 1996 Revolving Credit Facility contains
various terms and covenants which provide for certain restrictions on the
Company's indebtedness, liens, investments, disposition of assets and mergers
and acquisitions and require the Company, among other things, to maintain
minimum levels of consolidated net worth and certain minimum financial ratios.
The borrower under the 1996 Revolving Credit Facility is DecisionOne
Corporation. Repayment of the debt is guaranteed by the Company and its other
subsidiaries except for its Canadian subsidiary.
 
     The Company's debt agreements and other agreements to which it is a party
contain certain covenants restricting the payment of dividends on, or
repurchases of, Company common stock.
 
     The Company had average borrowings of $221,069,000 and $172,065,000 during
1997 and 1996, respectively, at an average interest rate of 6.4% and 8.69%,
respectively. Maximum borrowings during 1997 and 1996 were $243,350,000 and
$268,748,000, respectively.
 
     Subsequent to June 30, 1997, in connection with the Company's merger with
Quaker (see Note 3), the 1996 Revolving Credit Facility was repaid in full,
including all interest due thereon. This refinancing was accomplished, in part,
through the issuance of certain new debt instruments, consisting of senior
discount notes, senior subordinated notes and a term loan/revolving credit
facility which, in the aggregate, provide financing of approximately $810
million, subject to certain conditions. The new revolving credit facility
provides the Company with $105 million of available financing, subject to a
borrowing base, for working capital purposes subsequent to the merger.
 
     The Company's Canadian subsidiary has available a $1.5 million (Canadian)
revolving line of credit agreement with a local financial institution. At June
30, 1997, approximately $471,000 (in U.S. dollars) was outstanding under this
agreement. There were no amounts outstanding at June 30, 1996.
 
SELLER NOTES PAYABLE
 
     In connection with certain acquisitions (see Note 4), the Company issued
noninterest-bearing notes, the principal of which is primarily due upon
settlement of contingent portions of the acquisition purchase price within a
specified period subsequent to closing, generally not exceeding one year from
the acquisition date. Contingencies typically pertain to actual amounts of
monthly maintenance contract revenues acquired and prepaid contract liabilities
assumed in comparison to amounts estimated in acquisition agreements. The
Company imputes interest, based upon market rates, for long-term,
non-interest-bearing obligations.
 
     During 1997, the Company issued a secured note payable to the seller for
the purchase of repairable parts in the original amount of $1,854,000. The note
accrues interest at an interest rate of approximately 8%, and requires quarterly
payments of principal and interest of approximately $273,000 until maturity in
December 1998.

     In connection with the BABSS acquisition (see Note 4) on October 20, 1995,
the Company issued and sold to its principal shareholders, an aggregate
$30,000,000 principal amount of 10.101% Debentures (the "Affiliate Notes") due
on October 20, 2001. The Affiliate Notes were subordinated to the 1995 Term Loan
and the revolving credit facility. Interest on the Affiliate Notes was payable
semiannually on the last business day of June and December of each year
commencing on December 31, 1995.
 
     In connection with the issuance of the debentures, the Company issued
468,750 Common Stock Purchase Warrants (the "Warrants"). Each Warrant initially
entitled the owner to buy one share of Common Stock for $0.10. The number of
shares that can be purchased per Warrant steps up over 24 months in conjunction
with the increasing conversion privilege applicable to the Preferred Stock such
that, at the end of 24 months, each Warrant entitled the holder to buy
approximately 1.21 shares of Common Stock at a price of

$0.10 per share. The Warrants were exercisable from October 20, 1997 until
October 20, 2001, provided that if the Company had a public offering of its
Common Stock meeting certain requirements before October 20, 1997, the Warrants
became exercisable at the time of the public offering and the number of shares
that could be purchased on exercise was fixed at that time and no longer
increased in steps. The Warrants also became exercisable upon retirement of the
Debentures. Each Warrant had an assigned value of $7.25333 which resulted in an
original issue discount of $3,400,000 which was being amortized over the term of
the Affiliate Notes. Upon consummation of its initial public offering in April
1996, the Company was required to pay up to the total amount outstanding under
the Affiliate Notes and, accordingly, the Company used $30,000,000 of the
proceeds to retire the Affiliate Notes. As a result, in 1996 the Company
recorded an extraordinary loss in the amount of $3,211,000, net of taxes of
$1,284,000, due to the acceleration of the amortization of original issue
discount. In connection with the Company's merger with Quaker in August 1997
(see Note 3), the Warrants were converted into cash, with warrant holders
receiving an amount equal to $23 less the exercise price for each Warrant.
 
     In connection with previous credit agreements, the Company issued warrants
to purchase shares of the Company's common stock. At June 30, 1997, warrants to
purchase 134,478 shares at an exercise price of $5.90 per share remained
outstanding. In connection with the Company's merger with Quaker, these warrants
were also converted into cash, with warrant holders receiving an amount equal to
$23 less the exercise price for each warrant.

     As a result of the Company's initial public offering in April, 1996, an
"ownership change" occurred pursuant to Section 382 of the Internal Revenue
Code. Accordingly, for Federal income tax purposes, net operating loss and tax
credit carryforwards arising prior to the ownership change are limited during
any future period to the Section 382 "limitation amount" of approximately $20.0
million per annum. In addition, the Company's merger with Quaker on August 7,
1997 (see Note 3) represents another such "ownership change" pursuant to Section
382. The Company estimates that the limitation on the use of tax loss
carryforwards and other credits, for Federal income tax purposes, in any
post-merger period will be reduced to approximately $9.0 million per annum.

     The Company has recorded a deferred tax asset of $4,868,000 reflecting the
benefit of federal and state net operating loss carryforwards, which expire in
varying amounts between 1998 and 2008. Realization depends on generating
sufficient taxable income before expiration of the loss carryforwards. Although
realization is not assured, management believes it is more likely than not that
all of the deferred tax asset will ultimately be realized.
 
     The valuation allowance for deferred tax assets as of July 1, 1994 was
$44,160,000. The net changes in the valuation allowance for the years ended June
30, 1996 and 1995 were decreases of $686,000 and $43,474,000, respectively. Of
these amounts, $252,000 and $8,982,000 resulted from the realization of net
operating loss carryforwards. The remaining decreases of $434,000 and
$34,492,000 for 1996 and 1995, respectively, resulted from the Company's
expected future taxable income.

     As more fully described in Note 15, accrued severance and unutilized lease
losses represent remaining liabilities for estimated future employee severance
costs and for lease/contract losses associated with duplicate facilities to be
closed. These liabilities were recorded by the Company in connection with the
Memorex Telex and BABSS acquisitions in November 1996 and October 1995,
respectively.
 
     Other noncurrent liabilities include deferred operating lease liabilities
related to scheduled rent increases, recorded in accordance with the provisions
of SFAS No. 13, Accounting for Leases. Also included in other noncurrent
liabilities are provisions relating to various tax matters.
 
11.  STOCK OPTION AND RESTRICTED STOCK PURCHASE PLAN
 
     Under the 1988 Stock Option and Restricted Stock Purchase Plan, the name of
which was subsequently changed to DecisionOne Stock Option and Restricted Stock
Purchase Plan (the "Plan"), the Company, at the discretion of the Board of
Directors, may issue restricted stock, incentive stock options and non-qualified

options for shares of the Company's common stock. Vesting of the restricted
stock and stock options is at the discretion of the Board of Directors and
generally occurs at a rate of 25% per year.
 
     During 1994, the Board of Directors amended the Plan increasing the total
number of shares issuable to approximately 2,350,000. Additionally, in November
1995 the Board of Directors amended the Plan increasing the total number of
shares issuable to approximately 3,350,000, and in December 1996 to 5,350,000.
 
     The price of the incentive stock options issued to employees under the Plan
is not less than 100% of the fair market value of the common shares at the date
of issuance. The option price for nonqualified options is determined by the
Board of Directors at the time of grant and may be less than the fair market
value of the common shares at the time of grant. However, no such options were
granted at prices less then 100% of the fair value of common shares at the date
of issuance.
 
     Options expire through February 2007. Restricted shares which are not
vested upon an employee's termination are subject to a repurchase right of the
Company at a price equal to the amount paid by the employee.
 
     Presented below is the activity in the Plan for the years ended June 30,
1997, 1996 and 1995:

payments equal to the excess, if any, of $23.00 over the exercise price of each
option. Certain option holders were afforded the opportunity to convert these
options into options to purchase common stock of the merged Company, in lieu of
cash payments.
 
     Pursuant to the 1997 Management Incentive Plan approved subsequent to the
Merger, the Company granted 1,179,000 options at a weighted average exercise
price of approximately $20.61 with a weighted average fair market value of
$11.23.

     Because the Company accounts for the Plan under APB No. 25, no compensation
cost has been recognized for stock options. Had compensation expense for the
Plan been determined based on the fair value at the grant dates under the
provisions of SFAS No. 123, the Company's pro forma net loss and pro forma loss

     Rental expense amounted to approximately $17,367,000, $13,149,000 and
$5,878,000, for the fiscal years ended 1997, 1996 and 1995, respectively.
 
13.  SHAREHOLDERS' EQUITY
 
     During fiscal 1994 and 1996, the Company issued three classes of redeemable
preferred stock (Series A, Series B and Series C preferred stock; collectively,
the "Preferred Stock"), aggregating 376,416 preferred stock shares, in exchange
for cash or in settlement of certain debt obligations. The Preferred Stock,
which was valued at $100 per share, accrued dividends at rates ranging between
$4 per share per annum and $6 per share per annum, to be paid as declared by the
Company's Board of Directors. Additionally, the Preferred Stock was to be
automatically converted into Company common stock if the Company were to
complete a public offering of common stock which met certain specified criteria.
 
     On February 9, 1996, the Company amended its Certificate of Incorporation
to increase the number of authorized shares of common stock to 100,000,000
shares and to authorize 5,000,000 shares of Preferred Stock.

                  DECISIONONE HOLDINGS CORP. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In April 1996, the Company completed a public offering of 6,300,000 shares
of common stock at $18.00 per share (the "Offering"). Prior to the Offering,
there was no public market for the Company's common stock. The common stock is
listed on the Nasdaq National Market under the symbol "DOCI".
 
     The net proceeds of the offering, after deducting applicable issuance costs
and expenses were $104,740,000. The proceeds were used to repay approximately
$70,000,000 of the 1995 Term Loan, $30,000,000 in Affiliate Notes, approximately
$1,446,000 in accrued and declared dividends to holders of the Preferred Stock
and for other general corporate purposes. In connection with the offering, the
Preferred Stock was automatically converted into 11,271,924 shares of common
stock.
 
     During the year ended June 30, 1996, certain shareholders exercised their
preemptive right to subscribe for and purchase additional shares of common stock
or other securities so issued at the same price as originally issued on certain
occasions from 1992 through 1995. On December 4, 1995, the following securities
were purchased: (a) 382,578 shares of common stock at a price of $4 per share;
(b) 999 shares of Series A Preferred Stock, at a price of $100 per share; (c)
1,776 shares of Series B Preferred Stock, at a price of $100 per share; (d)
1,924 shares of common stock at a price of $.50 per share; (e) 311,141 shares of
Series C Preferred Stock, at a price of $100 per share; and (f) 17,407 Common
Stock Purchase Warrants at a price of $7.25333 per warrant which entitles the
holder to purchase 17,407 shares of common stock at an exercise price of $.10
per share. The 17,407 Common Stock Purchase Warrants were exercised in 1996.
 
     In consideration of his service as a director and Chairman of the Board,
the Company, in a prior year, granted an individual warrants to purchase an
aggregate of 66,667 shares of common stock at an exercise price of $4.00 per
share. In connection with the Company's merger with Quaker in August 1997 (see
Note 3), these warrants were converted into cash, with the holder receiving an
amount equal to $23 less the exercise price.
 
     As more fully described in Note 3, the Company merged with Quaker on August
7, 1997. In accordance with the terms of the Merger Agreement, which was
formally approved by the Company's shareholders on August 7, 1997, Quaker merged
with and into the Company, and the holders of approximately 94.7% of shares of
Company common stock outstanding immediately prior to the merger received $23 in
cash in exchange for these shares. Holders of approximately 5.3% of shares of
Company common stock outstanding immediately prior to the merger retained such
shares in the merged Company, as determined based upon shareholder elections and
stock proration factors specified in the Merger Agreement. Immediately following
the merger, continuing shareholders owned approximately 11.9% of shares of
outstanding Company common stock. The aggregate value of the merger transaction
was approximately $940 million, including refinancing of the Company's revolving
credit facility (see Note 8).
 
14.  RETIREMENT PLANS
 
     The Company maintains a 401(k) plan for its employees which is funded
through the contributions of its participants. A similar plan exists for former
employees of an acquired company for which eligibility and additional
contributions were frozen in September 1988.
 
     In addition, the Company assumed the liability of the defined benefit
pension plan applicable to employees of a company acquired in 1986. The
eligibility and benefits were frozen as of the date of the acquisition.

15.  EMPLOYEE SEVERANCE AND UNUTILIZED LEASE COSTS
 
     During the second quarter of fiscal 1997, in connection with the Memorex
Telex acquisition (see Note 4), the Company recorded a $3.4 million pre-tax
charge for estimated future employee severance costs, and a $0.9 million pre-tax
charge for unutilized lease/contract losses ("exit costs"), primarily associated
with duplicate facilities to be closed. The $3.4 million charge, recorded in
accordance with SFAS No. 112, Employers' Accounting for Postemployment Benefits,
reflects the actuarially determined benefit costs for the separation of
employees who are entitled to benefits under pre-existing separation pay plans.
These costs are included in selling, general and administrative expenses in the
accompanying consolidated statement of operations for the year ended June 30,
1997.
 
     In the second quarter of fiscal 1996, in connection with the acquisition of
BABSS, the Company recorded pre-tax charges for exit costs of $6.9 million, and
estimated future employee severance costs of $0.1 million. During the fourth
quarter of fiscal 1996, the Company reversed $3.4 million of these employee
severance and exit cost liabilities. The reversal was primarily the result of
the Company's ability to utilize and sublease various facilities identified in
the original $7.0 million combined liability. Such information was unknown to
the Company when the original liability was recorded.
 
     See Note 10 for further information regarding accrued severance and
unutilized lease losses.
 
16.  COMMITMENTS AND CONTINGENT LIABILITIES
 
     The Company, or certain businesses as to which it is alleged that the
Company is a successor, have been identified as potentially responsible parties
in respect to four waste disposal sites that have been identified by the United
States Environmental Protection Agency as Superfund sites. In addition, the
Company received a notice several years ago that it may be a potentially
responsible party with respect to a fifth, related site, but

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
has not received any other communication with respect to that site. Under
applicable law, all parties responsible for disposal of hazardous substances at
those sites are jointly and severally liable for clean-up costs. The Company
originally estimated that its share of the costs of the clean-up of one of these
sites would be approximately $500,000 which is provided for in liabilities
related to the discontinued products division in the accompanying consolidated
balance sheets as of June 30, 1997 and 1996. Complete information as to the
scope of required clean-up at these sites is not yet available and, therefore,
management's evaluation may be affected as further information becomes
available. However, in light of information currently available to management,
including information regarding assessments of the sites to date and the nature
of involvement of the Company's predecessor at the sites, it is management's
opinion that the Company's potential additional liability, if any, for the cost
of clean-up of these sites will not be material to the consolidated financial
position, results of operations or liquidity of the Company.
 
     The Company is also party to various legal proceedings incidental to its
business. Certain claims, suits and complaints arising in the ordinary course of
business have been filed or are pending against the Company. In the opinion of
management, these actions can be successfully defended or resolved without a
material adverse effect on the Company's consolidated financial position,
results of operations or liquidity.
 
     During the fourth quarter of fiscal 1997, the Company received $2.0 million
in full settlement of a claim against its former insurance carrier, related to
unreimbursed losses. This settlement was reflected as a reduction of selling,
general and administrative costs in the accompanying statement of operations.
 
17.  RELATED PARTY TRANSACTIONS
 
     Prior to 1994, the Company entered into an agreement to purchase printer
products from Genicom Corporation (Genicom). The Company and Genicom are under
common ownership. The initial term of the agreement is for five years with an
option to extend based on mutual agreement of the parties. Purchases from
Genicom for the years ended June 30, 1997, 1996 and 1995 were approximately
$472,000, $1,512,000 and $1,972,000, respectively. Accounts payable to Genicom
amounted to approximately $30,000 and $14,000 as of June 30, 1997 and 1996,
respectively.
 
     During the year ended June 30, 1996, the Company paid approximately
$125,000 for expense reimbursements to certain shareholders for services
rendered in connection with an acquisition in 1988. The amount was accrued for
in prior years.
 
     In connection with the Company's financing of the BABSS acquisition on
October 20, 1995, the Company issued subordinated debentures and redeemable
preferred stock to certain related parties (see Notes 8 and 13).

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Shareholder
  of DecisionOne Corporation:
 
     We have audited the accompanying consolidated balance sheets of DecisionOne
Corporation (a wholly-owned subsidiary of DecisionOne Holdings Corp.) and
subsidiaries (the "Company") as of June 30, 1997 and 1996, and the related
consolidated statements of operations, shareholders' equity and cash flows for
each of the three years in the period ended June 30, 1997. Our audits also
included the related financial statement schedule listed in the Index at Item
14. These financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement schedule 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, such consolidated financial statements present fairly, in
all material respects, the financial position of DecisionOne Corporation and
subsidiaries as of June 30, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1997 in conformity with generally accepted accounting principles. Also, in our
opinion, the financial statement schedule, when considered in relation to the
basic financial statements taken as a whole, presents fairly in all material
respects the information set forth therein.
 
     As discussed in Note 1 to the consolidated financial statements, on May 29,
1997, DecisionOne Holdings Corp. completed a restructuring of the legal
organization of certain of its subsidiaries. The Company's consolidated
financial statements have been presented giving effect to the reorganization for
all periods presented in a manner similar to a pooling of interests.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                    YEARS ENDED JUNE 30, 1997, 1996 AND 1995
 
1.  NATURE OF BUSINESS
 
     DecisionOne Corporation (a wholly-owned subsidiary of DecisionOne Holdings
Corp., herein called "Holdings") and its wholly-owned subsidiaries (the
"Company") are providers of multivendor computer maintenance and technology
support services. The Company offers its customers a single-source, independent
(i.e., not affiliated with an original equipment manufacturer, or "OEM")
solution for computer maintenance and technology support requirements, including
hardware maintenance services, software support, end-user/ help desk services,
network support and other technology support services. These services are
provided by the Company across a broad range of computing environments,
including mainframes, midrange and distributed systems, workgroups, personal
computers ("PCs") and related peripherals. In addition, the Company provides
outsourcing services for OEMs, software publishers, system integrators and other
independent service organizations. The Company delivers its services through an
extensive field service organization of approximately 4,000 field technicians in
over 150 service locations throughout North America and through strategic
alliances in selected international markets.
 
     Through June 30, 1995, the Company's services predominantly involved the
provision of maintenance services to the midrange computer market. On October
20, 1995, the Company acquired Bell Atlantic Business Systems Services, Inc.
("BABSS") (see Note 4). BABSS provided computer maintenance and technology
support services for computer systems ranging from the data center, which
includes both mainframe and midrange systems, to desk top. Subsequent to the
acquisition, Holding's principal operating subsidiary, Decision Servcom, Inc.,
was merged into BABSS, which had changed its name to DecisionOne Corporation. As
a result, DecisionOne Corporation is the principal operating subsidiary of the
Holdings.
 
     On May 29, 1997, DecisionOne Holdings Corp. Holdings Corp. ("Holdings")
completed a restructuring of the legal organization of its subsidiaries (the
"Corporate Reorganization"). The Corporate Reorganization involved Holdings'
contribution to DecisionOne Corporation of ownership interests in its
subsidiaries, all of which were under Holdings' control (the "Contributed
Subsidiaries"). The Corporate Reorganization has been accounted for in a manner
similar to a pooling of interests. Accordingly, the Company's consolidated
financial statements include the accounts of the Contributed Subsidiaries for
all periods presented.
 
     The Company's wholly owned, direct international subsidiaries are not
significant to the Company's consolidated financial statements.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
     Consolidation -- The consolidated financial statements include the accounts
of DecisionOne Corporation and its wholly owned subsidiaries. All significant
intercompany balances and transactions have been eliminated in consolidation.
 
     Pro Forma Information (Unaudited) -- The pro forma information included in
the accompanying statement of operations and in Note 3 has been prepared to
reflect the Company's and Holding's recapitalization and merger with Quaker
Holding Co. ("Quaker") and related transactions as if these had occurred on July
1, 1996.
 
     Cash and Cash Equivalents -- Cash and cash equivalents are highly liquid
investments with remaining maturities of three months or less at the time of
purchase. Cash equivalents, consisting primarily of repurchase agreements with
banks, are stated at cost, which approximates fair market value.
 
     Consumable Parts and Repairable Parts -- In order to provide maintenance
and repair services to its customers, the Company is required to maintain
significant levels of computer parts. These parts are classified as consumable
parts or as repairable parts. Consumable parts, which are utilized during the
repair process, are
 
                                      F-31
<PAGE>   63
 
                    DECISIONONE CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
stated at cost, principally determined using the weighted average method, less
an accumulated allowance for obsolescence and shrinkage. Consumable parts are
reflected in cost of revenues during the period utilized.
 
     Repairable (rotable) parts, which can be refurbished and reused, are stated
at original cost less accumulated amortization. Amortization of repairable parts
is reflected in cost of revenues. Costs of refurbishing repairable parts are
also included in cost of revenues as these costs are incurred. Amortization of
repairable parts is based principally on the composite group method, using
straight-line composite rates. Repairable parts generally have an economic life
which corresponds to the normal life cycle of the related products, currently
estimated to be three to five years.
 
     As consumable and repairable parts are retired, the weighted average gross
amounts at which such parts have been carried are removed from the respective
assets accounts, and charged to the accumulated allowance or accumulated
amortization accounts, as applicable. Periodic revisions to amortization and
allowance estimates are required, based upon the evaluation of several factors,
including changes in product life cycles, usage levels and technology changes.
Changes in these estimates are reflected on a prospective basis unless such
changes result from an extraordinary retirement or from other events or
circumstances which indicate that impairment may exist. Impairment is recognized
when the net carrying value of the parts exceeds the estimated current and
anticipated undiscounted net cash flows. Measurement of the amount of
impairment, if any, is calculated based upon the difference between carrying
value and fair value.
 
     Property and Equipment -- Property and equipment are stated at cost.
Depreciation is provided for using the straight-line method over the estimated
useful lives of the depreciable assets. Capitalized equipment leases and
leasehold improvements are amortized over the shorter of the related lease terms
or asset lives. Maintenance and repairs are charged to expense as incurred. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is charged to operations.
 
     Business and Contract Acquisitions -- Business and contract acquisitions
have been accounted for as purchase transactions, with the purchase price of
each acquisition allocated to the assets acquired and liabilities assumed based
upon their respective estimated fair values at the dates of acquisition.
Consistent with the Company's parts retirement accounting methods, the gross
value of parts acquired is generally stated at weighted average cost. Fair value
adjustments, if any, are reflected as adjustments to the respective accumulated
amortization or allowance accounts. The excess of the purchase price over
identified net assets acquired is amortized, on a straight-line basis, over the
expected period of future benefit (see Note 6).
 
     Typical contract acquisitions are comprised primarily of customer
maintenance and support contracts of complementary entities, along with the
accompanying consumable and repairable parts required to support these contracts
and other identifiable intangibles, such as noncompete agreements. Liabilities
assumed in business and contract acquisitions consist primarily of prepaid
amounts related to multi-period customer maintenance and support contracts.
These liabilities are recorded as deferred revenues at acquisition dates and are
recognized as revenues when earned in accordance with the terms of the
respective contracts.
 
     Intangible Assets -- Intangible assets are comprised of excess purchase
price over the fair value of net assets acquired, acquired customer lists and
other intangible assets, including the fair value of contractual profit
participation rights and amounts assigned to noncompete agreements.
 
     Intangible assets, which arise principally from acquisitions, are generally
amortized on a straight-line basis over their respective estimated useful lives
(see Note 6). The Company evaluates the carrying value of intangible assets
whenever events or changes in circumstances indicate that these carrying values
may not be recoverable within the amortization period. Impairment is recognized
when the net carrying value of the intangible asset exceeds the estimated
current and anticipated discounted future net cash flows. Measurement of the
amount of impairment, if any, is calculated based upon the difference between
carrying value and fair value.

                    DECISIONONE CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Revenue -- The Company enters into maintenance contracts whereby it
services various manufacturers' equipment. Revenues from these contracts are
recognized ratably over the terms of such contracts. Prepaid revenues from
multi-period contracts are recorded as deferred revenues and are recognized
ratably over the term of the contracts.
 
     Revenues derived from the maintenance of equipment not under contract are
recognized as the service is performed. Revenues derived from other technology
support services are recognized as the service is performed or ratably over the
term of the contract.
 
     Foreign Currency Translation -- Gains and losses resulting from foreign
currency translation are accumulated as a separate component of shareholders'
equity. Gains and losses resulting from foreign currency transactions are
included in operations.
 
     Credit Risk -- Concentration of credit risk with respect to trade
receivables is limited due to the large number of customers comprising the
Company's customer base and their dispersion across many industries.
 
     Fair Value of Financial Instruments -- The following disclosures of the
estimated fair value of financial instruments were made in accordance with the
requirements of SFAS No. 107, Disclosures about Fair Value of Financial
Instruments. The estimated fair value amounts have been determined by the
Company using available market information and appropriate valuation
methodologies.
 
          Cash and Cash Equivalents, Accounts Receivable, and Accounts
     Payable -- The carrying amount of these items are a reasonable estimate of
     their fair value.
 
          Short-Term Debt and Long-Term Debt -- As more fully described in Note
     8, under its revolving borrowing facility the Company incurs interest at
     variable rates based upon market conditions (i.e., based upon the prime
     rate or LIBOR). Rates applicable to other debt instruments, which consist
     primarily of short-term notes payable in connection with certain
     acquisitions, are comparable to those of similar instruments currently
     available to the Company. Accordingly, the carrying amount of debt is a
     reasonable estimate of its fair value.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results may differ from those estimates and
assumptions.
 
     Discontinued Operations -- During fiscal 1993, in connection with the sale
of its products division, the Company established estimated liabilities relating
to the settlement of the remaining assets and liabilities of this division. In
1995, the Company revised its estimates as a result of settlement of these
liabilities, and the consolidated statement of operations for 1995 reflects an
increase in net income of $1,113,000 for the change in estimate.
 
     Derivative Financial Instruments -- Derivative financial instruments, which
constitute interest rate swap agreements (see Note 8), are periodically used by
the Company in the management of its variable interest rate exposure. Amounts to
be paid or received under interest rate swap agreements are recognized as
interest expense or interest income during the period in which these accrue.
Gains realized, if any, on the early termination of interest rate swap contracts
are deferred, to be recognized upon the termination of the related asset or
liability or expiration of the original term of the swap contract, whichever is
earlier. The Company does not hold any derivative financial instruments for
trading purposes.
 
     Reclassifications -- Certain reclassifications have been made to the 1996
balances in order to conform with the 1997 presentation.

3.  MERGER, RECAPITALIZATION AND PRO FORMA INFORMATION
 
     On August 7, 1997, the Company and Holdings consummated a merger with
Quaker Holding Co. ("Quaker"), an affiliate of DLJ Merchant Banking Partners II.
The merger, which will be recorded as a recapitalization for accounting purposes
as of the consummation date, occurred pursuant to an Agreement and Plan of
Merger (the "Merger Agreement") by and among the Company, Holdings and Quaker
dated May 4, 1997. The accompanying historical consolidated financial statements
do not include any adjustments with respect to the consummation of the merger.
 
     In accordance with the terms of the Merger Agreement, which was formally
approved by the Company's shareholders on August 7, 1997, Quaker merged with and
into Holdings, and the holders of approximately 94.7% of shares of Holdings
common stock outstanding immediately prior to the merger received $23 in cash in
exchange for each of these shares. Holders of approximately 5.3% of shares of
Holdings common stock outstanding immediately prior to the merger retained such
shares in the merged Holdings, as determined based upon shareholder elections
and stock proration factors specified in the Merger Agreement. Immediately
following the merger, continuing shareholders owned approximately 11.9% of
shares of outstanding Holdings common stock. The aggregate value of the merger
transaction was approximately $940 million, including refinancing of the
Company's revolving credit facility (see Note 8).
 
     In connection with the merger, Holdings raised $85 million through the
public issuance of discount debentures, and the Company issued publicly-held
subordinated notes for approximately $150 million. The Company also entered into
a new syndicated credit facility providing for term loans of $470 million and
revolving loans of up to $105 million. The proceeds of the discount notes,
subordinated notes and the initial borrowings under the new credit facility
along with a loan of approximately $59.1 million from the Company to Holdings
and the purchase of approximately $225 million of Holdings common stock by
Quaker have been used to finance the payments of cash to cash-electing Holdings
shareholders, to pay the holders of Holdings stock options and stock warrants
canceled or converted, as applicable, in connection with the merger, to repay
the Company's existing revolving credit facility and to pay expenses incurred in
connection with the merger.
 
     As a result of the merger, the Company and Holdings incurred various
expenses, aggregating approximately $71 million on a pretax basis (approximately
$64 million after related tax benefit), subject to adjustment, in connection
with consummating the transaction. These costs consisted primarily of
compensation costs, underwriting discounts and commissions, professional and
advisory fees and other expenses. The Company will report this one-time charge
during the first quarter of fiscal 1998. In addition to these expenses, the
Company and Holdings also incurred approximately $22.3 million of capitalized
debt issuance costs associated with the merger financing. These costs will be
charged to expense over the terms of the related debt instruments.
 
     The following summarized unaudited pro forma information of the Company as
of and for the year ended June 30, 1997 assumes that the merger had occurred on
July 1, 1996. The pro forma results have been prepared for comparative purposes
only and do not purport to be indicative of the financial condition or of the
results of operations which actually would have resulted had the merger occurred
as of July 1, 1996 or which may result in the future.

     On August 31, 1994, the Company purchased certain net assets and
liabilities of IDEA/Servcom, Inc. for approximately $29,500,000. This
acquisition was funded by cash and the issuance of a $2,600,000 noninterest-
bearing note to the seller. See seller notes payable section of Note 8. The
excess of asset purchase price over the fair value of net assets acquired at the
date of purchase was approximately $7,400,000.
 
     On October 20, 1995, the Company acquired all of the outstanding common
stock of BABSS, a subsidiary of Bell Atlantic Corporation ("BAC") for
approximately $250,549,000. The acquisition was funded with the proceeds from
the issuance of $30,000,000 of Series C preferred stock, $30,000,000 of
subordinated debentures and the balance from additional bank borrowings (see
Notes 8 and 13). The excess of asset purchase price over the fair value of net
assets acquired at the date of purchase was initially recorded as approximately
$58,796,000. Subsequent to the acquisition, the Company recorded a net
adjustment increasing the initial amount by $1,737,000 and adjusted other
balance sheet accounts principally by the same amount. This resulted from the
adjustment and reclassification of certain tax accruals offset by favorable
negotiations on certain leased facilities (see Note 7). As part of the
acquisition, the Company purchased from BAC contractual profit participation
rights whereby the Company will receive a fixed percentage of the annual
operating profits (3.2% or 3.5%, depending upon the level of profits) earned by
a former foreign affiliate of

BAC which provides computer maintenance and technology support services in
Europe. The estimated value of the discounted estimated future cash flows over a
twenty-year period from these contractual profit participation rights is
$25,000,000.
 
     Included in nonsignificant maintenance contract acquisitions is the
acquisition of substantially all of the contracts and related assets, including
spare parts of the U.S. computer service business of Memorex Telex Corporation
and certain of its affiliates (collectively, "Memorex Telex"). Memorex Telex had
filed a petition in bankruptcy in the United States Bankruptcy Court (the
"Court") in the District of Delaware on October 15, 1996; the Court approved the
sale to the Company on November 1, 1996. The adjusted purchase price was $52.7
million, comprised of the assumption of certain liabilities under contracts of
the service business, which were valued at $28.3 million, and base cash
consideration of approximately $24.4 million, after certain purchase price
adjustments, excluding transaction and closing costs.
 
     The estimated fair market values of certain assets acquired, as well as
liabilities assumed, are subject to further adjustment as additional information
becomes available to the Company. During the third quarter of fiscal 1997, the
Company recorded an adjustment increasing the deferred revenues assumed in the
Memorex Telex acquisition by approximately $2,300,000, to revise the estimated
fair value of certain contract liabilities of the business assumed by the
Company.
 
     The following summarized unaudited pro forma information for significant
acquisitions that have a material effect on the Company's results of operations
for the years ended June 30, 1996 and 1995 assumes that the acquisitions
occurred as of July 1, 1994. The nonsignificant business and maintenance
contract acquisitions are not considered material individually or in the
aggregate. The pro forma results have been prepared for comparative purposes
only and do not purport to be indicative of the results of operations which
actually would have resulted had the significant acquisitions been in effect on
the dates indicated or which may result in the future.

     Prior to 1994, the Company received $2,600,000 in tax bills (primarily
interest) from the Internal Revenue Service ("IRS") related to claims for tax
and interest for the years 1981 through 1987. The Company paid approximately
$500,000 of the claims upon receipt of the bills. Although the Company disputed
the tax bills, an IRS mandated payment of $828,000 was made in 1996. As of June
30, 1996, the

Company had an accrued liability of $1,883,000 related to this assessment.
During fiscal 1997, the Company paid $1,729,000 in full settlement of these tax
and interest bills.
 
     In connection with the acquisition of BABSS, which has been accounted for
using the purchase method of accounting (see Note 4), the Company recorded
approximately $11,000,000 in liabilities resulting from planned actions with
respect to BABSS, which included the costs to exit certain leased facilities and
to involuntarily terminate employees. The provision of approximately $3,500,000
for the costs to exit certain leased facilities principally relates to future
lease payments on a warehouse in California which has been made idle.
Approximately $4,000,000 was provided for severance and termination benefits of
approximately 210 employees in the field, operations support, sales and
administration. Approximately $3,000,000 was provided in connection with the
exit plan for write-downs of spare parts and equipment at two California
facilities which will not be utilized in future operations. The provision for
various other charges of approximately $500,000 consisted of costs to complete
the exit plan. As of June 30, 1996, the Company had settled all of these
liabilities, except for the lease liabilities on idle facilities for which
payments were scheduled to continue through 1999 (see Note 15). At June 30, 1997
and 1996 remaining amounts due under these leases were $0 and $1,200,000,
respectively.
 
     As a result of successful negotiations of unutilized leased facilities,
during 1996, the Company recorded a reduction of approximately $975,000 to both
the provisions for leased facilities and excess purchase price over fair value
of net assets acquired.

REVOLVING CREDIT LOANS
 
     On October 20, 1995, in connection with the BABSS acquisition (see Note 4)
the Company entered into a Credit Agreement which provided for a term loan (the
"1995 Term Loan") of $230,000,000 and a revolving credit facility of up to a
maximum of $30,000,000. The 1995 Term Loan provided for 19 equal quarterly
principal payments of $10,000,000 to be due and payable on the last day of each
calendar quarter commencing December 31, 1995 with a final payment due on
September 30, 2000. Loans under the revolving credit facility were to mature on
September 30, 2000. Interest on the 1995 Term Loan and the revolving credit
facility were at varying rates based, at the Company's option, on the Eurodollar
rate or the Alternative Base Rate (NationsBanc prime rate), plus the Applicable
Margins. Margins were based on the ratio of Total Funded Debt to EBITDA; the
Eurodollar Margin ranged from 1.75% to 2.5%, while the Alternative Base Rate
Margin ranged from 0.5% to 1.25%.

1995 Term Loan.
 
     Also in April 1996, the Company converted the 1995 Term Loan and the
existing $30 million Revolving Credit Facility into a $225 million variable
rate, unsecured revolving credit facility ("the 1996 Revolving Credit
Facility"). During fiscal 1997, the 1996 Revolving Credit Facility commitment
was increased to $300 million, in connection with the acquisition of certain
contracts and assets. The 1996 Revolving Credit Facility is at floating interest
rates, based either on the LIBOR or prime rate, in either case plus an
Applicable Margin, at the Company's option. As of June 30, 1997, the applicable
rate was LIBOR plus .75% or approximately 6.5%. The 1996 Revolving Credit
Facility enables the Company to borrow up to $300 million in the form of
revolving credit loans with a maturity date of April 26, 2001 and with interest
periods determined principally on a quarterly basis. To offset the variable rate
characteristics of the borrowings, the Company entered into interest rate swap
agreements with two banks resulting in fixed interest rates of 5.4% on $40.0
million notional principal amount through December 1997 and 5.5% on another
$40.0 million notional principal amount through December 1998.
 
     During fiscal 1997, the Company terminated these swap agreements, resulting
in an insignificant gain which has been deferred to the first quarter of fiscal
1998.
 
     Under the terms of the 1996 Revolving Credit Facility, the Company may use
up to $25,000,000 for letters of credit, subject to the limitation of
$300,000,000 in total credit. As of June 30, 1997, letters of credit in the face
amount of $3,067,000 were outstanding.
 
     The loan agreement relating to the 1996 Revolving Credit Facility contains
various terms and covenants which provide for certain restrictions on the
Company's indebtedness, liens, investments, disposition of assets and mergers
and acquisitions and require the Company, among other things, to maintain
minimum levels of consolidated net worth and certain minimum financial ratios.
The borrower under the 1996 Revolving Credit Facility is DecisionOne
Corporation. Repayment of the debt is guaranteed by the Company, Holdings and
the Company's other subsidiaries except for its Canadian subsidiary.
 
     The Company's debt agreements and other agreements to which it is a party
contain certain covenants restricting the payment of dividends on, or
repurchases of, Holdings common stock.
 
     The Company had average borrowings of $221,069,000 and $172,065,000 during
1997 and 1996, respectively, at an average interest rate of 6.4% and 8.69%,
respectively. Maximum borrowings during 1997 and 1996 were $243,350,000 and
$268,748,000, respectively.
 
     Subsequent to June 30, 1997, in connection with the Company's and Holdings'
merger with Quaker (see Note 3), the 1996 Revolving Credit Facility was repaid
in full, including all interest due thereon. This refinancing was accomplished,
in part, through the issuance of certain new debt instruments, consisting of
senior discount notes, senior subordinated notes and a term loan/revolving
credit facility which, in the aggregate, provide financing of approximately $810
million (including financing obtained by Holdings), subject to certain
conditions. The new revolving credit facility provides the Company with $105
million of available financing, subject to a borrowing base, for working capital
purposes subsequent to the merger.
 
     The Company's Canadian subsidiary has available a $1.5 million (Canadian)
revolving line of credit agreement with a local financial institution. At June
30, 1997, approximately $471,000 (in U.S. dollars) was outstanding under this
agreement. There were no amounts outstanding at June 30, 1996.
 
SELLER NOTES PAYABLE
 
     In connection with certain acquisitions (see Note 4), the Company issued
noninterest-bearing notes, the principal of which is primarily due upon
settlement of contingent portions of the acquisition purchase price within a
specified period subsequent to closing, generally not exceeding one year from
the acquisition date.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Contingencies typically pertain to actual amounts of monthly maintenance
contract revenues acquired and prepaid contract liabilities assumed in
comparison to amounts estimated in acquisition agreements. The Company imputes
interest, based upon market rates, for long-term, non-interest-bearing
obligations.
 
     During 1997, the Company issued a secured note payable to the seller for
the purchase of repairable parts in the original amount of $1,854,000. The note
accrues interest at an interest rate of approximately 8%, and requires quarterly
payments of principal and interest of approximately $273,000 until maturity in
December 1998.
 
SUBORDINATED DEBENTURES
 
     In connection with the BABSS acquisition (see Note 4) on October 20, 1995,
the Company issued and sold to Holdings principal shareholders, an aggregate
$30,000,000 principal amount of 10.101% Debentures (the "Affiliate Notes") due
on October 20, 2001. The Affiliate Notes were subordinated to the 1995 Term Loan
and the revolving credit facility. Interest on the Affiliate Notes was payable
semiannually on the last business day of June and December of each year
commencing on December 31, 1995.
 
     In connection with the issuance of the debentures, Holdings issued 468,750
Common Stock Purchase Warrants (the "Warrants"). Each Warrant initially entitled
the owner to buy one share of Common Stock for $0.10. The number of shares that
can be purchased per Warrant steps up over 24 months in conjunction with the
increasing conversion privilege applicable to the Preferred Stock such that, at
the end of 24 months, each Warrant entitled the holder to buy approximately 1.21
shares of Common Stock at a price of $0.10 per share. The Warrants were
exercisable from October 20, 1997 until October 20, 2001, provided that if
Holdings had a public offering of its Common Stock meeting certain requirements
before October 20, 1997, the Warrants became exercisable at the time of the
public offering and the number of shares that could be purchased on exercise was
fixed at that time and no longer increased in steps. The Warrants also became
exercisable upon retirement of the Debentures. Each Warrant had an assigned
value of $7.25333 which resulted in an original issue discount of $3,400,000
which was being amortized over the term of the Affiliate Notes. Upon
consummation of Holdings initial public offering in April 1996, the Company was
required to pay up to the total amount outstanding under the Affiliate Notes
and, accordingly, the Company used $30,000,000 of the proceeds to retire the
Affiliate Notes. As a result, in 1996 the Company recorded an extraordinary loss
in the amount of $3,211,000, net of taxes of $1,284,000, due to the acceleration
of the amortization of original issue discount.

     As a result of the Company's initial public offering in April, 1996, an
"ownership change" occurred pursuant to Section 382 of the Internal Revenue
Code. Accordingly, for Federal income tax purposes, net operating loss and tax
credit carryforwards arising prior to the ownership change are limited during
any future period to the Section 382 "limitation amount" of approximately $20.0
million per annum. In addition, the Company's merger with Quaker on August 7,
1997 (see Note 3) represents another such "ownership change" pursuant to Section
382. The Company estimates that the limitation on the use of tax loss
carryforwards and other credits, for Federal income tax purposes, in any
post-merger period will be reduced to approximately $9.0 million per annum.
 
     A reconciliation between the provision (benefit) for income taxes, computed

</TABLE>
 
     The Company has recorded a deferred tax asset of $4,868,000 reflecting the
benefit of federal and state net operating loss carryforwards, which expire in
varying amounts between 1998 and 2008. Realization depends on generating
sufficient taxable income before expiration of the loss carryforwards. Although
realization is not assured, management believes it is more likely than not that
all of the deferred tax asset will be realized.
 
     The valuation allowance for deferred tax assets as of July 1, 1994 was
$44,160,000. The net changes in the valuation allowance for the years ended June
30, 1996 and 1995 were decreases of $686,000 and $43,474,000, respectively. Of
these amounts, $252,000 and $8,982,000 resulted from the realization of net
operating loss carryforwards. The remaining decrease of $434,000 and $34,492,000
for 1996 and 1995, respectively, resulted from the Company's expected future
taxable income.

12.  RETIREMENT PLANS
 
     The Company maintains a 401(k) plan for its employees which is funded
through the contributions of its participants. A similar plan exists for former
employees of an acquired company for which eligibility and additional
contributions were frozen in September 1988.
 
     In addition, the Company assumed the liability of the defined benefit
pension plan applicable to employees of a company acquired in 1986. The
eligibility and benefits were frozen as of the date of the acquisition.

13.  EMPLOYEE SEVERANCE AND UNUTILIZED LEASE COSTS
 
     During the second quarter of fiscal 1997, in connection with the Memorex
Telex acquisition (see Note 4), the Company recorded a $3.4 million pre-tax
charge for estimated future employee severance costs, and a $0.9 million pre-tax
charge for unutilized lease/contract losses ("exit costs"), primarily associated
with duplicate facilities to be closed. The $3.4 million charge, recorded in
accordance with SFAS No. 112, Employers' Accounting for Postemployment Benefits,
reflects the actuarially determined benefit costs for the separation of
employees who are entitled to benefits under pre-existing separation pay plans.
These costs are included in selling, general and administrative expenses in the
accompanying consolidated statement of operations for the year ended June 30,
1997.
 
     In the second quarter of fiscal 1996, in connection with the acquisition of
BABSS, the Company recorded pre-tax charges for exit costs of $6.9 million, and
estimated future employee severance costs of $0.1 million. During the fourth
quarter of fiscal 1996, the Company reversed $3.4 million of these employee
severance and exit cost liabilities. The reversal was primarily the result of
the Company's ability to utilize and sublease various facilities identified in
the original $7.0 million combined liability. Such information was unknown to
the Company when the original liability was recorded.
 
     See Note 10 for further information regarding accrued severance and
unutilized lease losses.
 
14.  COMMITMENTS AND CONTINGENT LIABILITIES
 
     The Company, or certain businesses as to which it is alleged that the
Company is a successor, have been identified as potentially responsible parties
in respect to four waste disposal sites that have been identified by the United
States Environmental Protection Agency as Superfund sites. In addition, the
Company received a notice several years ago that it may be a potentially
responsible party with respect to a fifth, related site, but

                    DECISIONONE CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
has not received any other communication with respect to that site. Under
applicable law, all parties responsible for disposal of hazardous substances at
those sites are jointly and severally liable for clean-up costs. The Company
originally estimated that its share of the costs of the clean-up of one of these
sites would be approximately $500,000 which is provided for in liabilities
related to the discontinued products division in the accompanying consolidated
balance sheets as of June 30, 1997 and 1996. Complete information as to the
scope of required clean-up at these sites is not yet available and, therefore,
management's evaluation may be affected as further information becomes
available. However, in light of information currently available to management,
including information regarding assessments of the sites to date and the nature
of involvement of the Company's predecessor at the sites, it is management's
opinion that the Company's potential additional liability, if any, for the cost
of clean-up of these sites will not be material to the consolidated financial
position, results of operations or liquidity of the Company.
 
     The Company is also party to various legal proceedings incidental to its
business. Certain claims, suits and complaints arising in the ordinary course of
business have been filed or are pending against the Company. In the opinion of
management, these actions can be successfully defended or resolved without a
material adverse effect on the Company's consolidated financial position,
results of operations or liquidity.
 
     During the fourth quarter of fiscal 1997, the Company received $2.0 million
in full settlement of a claim against its former insurance carrier, related to
unreimbursed losses. This settlement was reflected as a reduction of selling,
general and administrative costs in the accompanying statement of operations.
 
15.  RELATED PARTY TRANSACTIONS
 
     Prior to 1994, the Company entered into an agreement to purchase printer
products from Genicom Corporation (Genicom). The Company and Genicom are under
common ownership. The initial term of the agreement is for five years with an
option to extend based on mutual agreement of the parties. Purchases from
Genicom for the years ended June 30, 1997, 1996 and 1995 were approximately
$472,000, $1,512,000 and $1,972,000, respectively. Accounts payable to Genicom
amounted to approximately $30,000 and $14,000 as of June 30, 1997 and 1996,
respectively.
 
     During the year ended June 30, 1996, the Company paid approximately
$125,000 for expense reimbursements to certain shareholders for services
rendered in connection with an acquisition in 1988. The amount was accrued for
in prior years.
