                                    PART I
 
ITEM 1. BUSINESS
 
  AmeriSource Health Corporation, through its direct wholly-owned subsidiary
AmeriSource Corporation (referred to collectively as "AmeriSource" and the
"Company"), is the fourth largest full-service wholesale distributor of
pharmaceutical products and related health care services in the United States.
The Company serves its customers nationwide through 20 drug distribution
facilities and three specialty products distribution facilities. AmeriSource
is typically the primary source of supply to its customers and offers a broad
range of services designed to enhance the operating efficiencies and
competitive position of its customers and suppliers. The Company benefits from
a diverse customer base that includes hospitals and managed care facilities
(47%), independent community pharmacies (34%), and chain drug stores,
including pharmacy departments of supermarkets and mass merchandisers (19%).
 
  Over the past five years, AmeriSource has achieved significant growth in
revenues and operating income before unusual items. The Company's operating
revenues have increased from $3.7 billion in fiscal 1993 to $8.6 billion in
fiscal 1998, a compound annual growth rate of 18.6%, while operating income
before unusual items and amortization increased from $73.3 million in fiscal
1993 to $152.8 million in fiscal 1998, a compound annual growth rate of 15.8%.
The Company's growth is primarily the result of market share gains in existing
markets, geographic expansion and overall industry growth.
 
  AmeriSource Health Corporation was incorporated in Delaware in 1988. The
address of the principal executive office of the Company is 300 Chester Field
Parkway, Malvern, PA 19355. The telephone number is (610) 296-4480.
 
BUSINESS STRATEGY
 
  Over the past five years, AmeriSource has significantly expanded its
national presence as a leading, innovative wholesale distributor of
pharmaceutical products and related health care services. The Company believes
it is well-positioned to continue its revenue growth and increase operating
income through the execution of the following key elements of its business
strategy:
 
  . Expanding into New Geographic Markets. The Company believes that there
    are substantial opportunities to grow by expanding into new geographic
    areas by opening new distribution facilities and making selective,
    complementary acquisitions. Since October 1993, the Company has opened
    seven distribution facilities. In October 1993, the Company opened a
    facility in Dallas, Texas, and in November 1994, the Company opened two
    additional facilities, one each in Portland, Oregon and Springfield,
    Massachusetts. In June 1995, the Company opened a facility in Sacramento,
    California and in October 1995, a facility in Phoenix, Arizona was
    opened. In December 1995, the Company opened a facility in Orlando,
    Florida, and in August 1998, the Company opened its newest facility in
    Los Angeles, California. Each of these new facilities began operations
    with an existing customer base in its regional marketplace. In addition,
    in July 1995, the Company acquired Newbro Drug Company, a regional
    wholesale pharmaceutical distributor based in Idaho Falls, Idaho; in
    February 1996, the Company acquired Gulf Distribution Inc., a regional
    wholesale pharmaceutical distributor based in Miami, Florida; and in
    March 1997, the Company acquired Walker Drug Company, a regional
    wholesale pharmaceutical distributor based in Birmingham, Alabama. The
    Company believes that as industry consolidation pressures continue,
    additional opportunities may arise to selectively acquire additional
    local and regional drug wholesale companies, thereby facilitating
    expansion into new geographic areas and enhancement of its competitive
    position in existing markets.
 
  . Increasing Market Share in Existing Markets. The Company believes that it
    is well-positioned to continue to grow in its existing markets by: (i)
    providing superior distribution services coupled with advanced
    information systems to reduce costs throughout the pharmaceutical supply
    channel; (ii) continuing to develop or acquire specialty value-added
    services and programs to improve the competitiveness of its customers and
    suppliers; (iii) maintaining its low cost operating structure to ensure
    that the Company's services are priced competitively in the marketplace;
    and (iv) continuing its decentralized operating structure to respond to
    customers' needs more quickly and efficiently and to ensure the continued
 
                                       1
<PAGE>
 
   development of local and regional management talent. These factors have
   allowed AmeriSource to compete effectively in the marketplace and generate
   above-average industry sales growth over the last five years.
 
  . Continuing Growth of Specialty Services. The Company works closely with
    both customers and suppliers to develop an extensive range of specialty
    services. In addition to enhancing the Company's profitability, these
    services increase customer loyalty and strengthen the Company's overall
    role in the pharmaceutical supply channel. These services include:
 
    --ECHO(R), the Company's proprietary software system, provides
     sophisticated ordering and inventory management assistance to its
     hospital and retail customers. In addition to facilitating the primary
     supply and communications between the Company and its customers,
     ECHO(R) enables the Company's customers to reduce their costs by
     ordering more efficiently, selecting from best price alternatives and
     maintaining formulary compliance. With approximately 6,200 systems
     nationwide the Company believes that its installed base of systems is
     one of the largest and most sophisticated in the wholesale drug
     industry.
 
    --Family Pharmacy(R) enables small chain and independent community
     pharmacies to compete more effectively through: (i) access to disease
     management and pharmaceutical care programs; (ii) enhanced access to
     pharmaceutical benefit programs of large health care groups, including
     third-party payor programs, through Amerisource Performance Network;
     (iii) value-added merchandising programs, including private label
     product lines; and (iv) innovative advertising, marketing and
     promotional campaigns. With over 2,550 Family Pharmacy(R) member-
     stores, Family Pharmacy(R) in effect constitutes one of the largest
     drugstore chains in the United States.
 
    --The Company's Income Rx(R) program provides an integral value-added
     service to its retail and hospital pharmacy customers by continually
     reviewing the marketplace for generic products that offer the best
     price, quality and availability. With the increasing importance of
     generic pharmaceuticals, this program represents a significant
     opportunity for growth and profitability. In fiscal 1998, the Company
     focused on its AmeriSource Select(R) automatic substitution generic
     compliance program and currently has over 4,500 customers in the
     program. AmeriSource Select(R) provides customers additional profit
     opportunity by channeling generic purchasing to preferred products in
     order to reduce product acquisition cost and decrease redundancies in
     other generic products stocked by the Company and its customers.
     Revenues attributable to AmeriSource's sale of generic and multi-source
     pharmaceuticals (including the Income Rx(R) program) increased to
     approximately $665 million in fiscal 1998.
 
    --American Health Packaging(R) is the Company's pharmaceutical packaging
     division. In fiscal 1996, the Company expanded its packaging business
     by opening a new state-of-the-art facility in Columbus, Ohio in order
     to provide customized packaging solutions to both customers and
     suppliers. The facility is capable of packaging pharmaceuticals into
     both unit of use and unit dose formats which provide higher
     productivity, better controls, and improved profitability throughout
     the pharmaceutical supply channel.
 
    --MedAssess(TM) is the Company's innovative patient care program
     designed to help pharmacies generate new patient care revenue and
     differentiate themselves from their competition. MedAssess(TM) offers
     opportunities for pharmacies to expand their role in patient care by
     providing specialized services to help patients better manage drug
     therapy and wellness. MedAssess(TM) provides pharmacists with
     continuing education, self-directed training, the MedAssess(TM) patient
     care software, and technical and practice support. MedAssess(TM)
     CareBuilder SM programs provide all the materials and information
     needed to implement and promote a variety of practical, revenue-
     generating patient care services.
 
    --The Diabetes Shoppe(TM) program develops pharmacy-based diabetes care
     centers to market over 600 specialized products and training for the
     diabetes patient. The program offers a full spectrum of marketing
     tools, including direct mailings to customers, doctors, signage, radio
     advertising and much more. Since the acquisition of The Diabetes
     Shoppe(TM) in September 1996, membership has grown from 215 to over 525
     retail pharmacy members nationwide.
 
 
                                       2
<PAGE>
 
    --The Company's Health Services Plus(R) business distributes vaccines,
     injectables, plasma, and oncology products to alternate care sites
     such as clinics, physicians, and surgery centers. In addition, Health
     Services Plus(R) provides specialty distribution services such as
     warehousing, order processing, and telemarketing for pharmaceutical
     and medical companies requiring distribution of specialized niche
     products.
 
  . Maintain Low-Cost Operating Structure. AmeriSource believes it has the
    lowest operating cost structure among its four major national
    competitors. Over the past five years, the Company has significantly
    reduced operating expenses and investment in net working capital as a
    percentage of revenues. Specifically, the Company has reduced its selling
    and administrative expenses and depreciation as a percentage of operating
    revenues from 3.72% in fiscal 1993 to 3.13% in fiscal 1998. In addition,
    the Company continues to achieve productivity and operating income gains
    from continued investments in advanced management information systems,
    warehouse automation technology, and operating leverage due to increased
    volume per Rx distribution facility. The addition of new facilities was
    accomplished with minimal incremental investment in corporate overhead.
    As these facilities continue to expand in their regional markets, the
    Company believes that its growth and profitability will be further
    enhanced.
 
INDUSTRY OVERVIEW
 
  The Company has benefited from the significant growth of the full-service
drug wholesale industry in the United States. Industry sales grew from $30
billion in 1990 to $75 billion in 1997. The factors contributing to this
growth, and the sources of future growth for the industry, include (i) an
aging population, (ii) the introduction of new pharmaceuticals, (iii) the
increased use of outpatient drug therapies, (iv) a higher concentration of
distribution through wholesalers by both manufacturers and customers, and (v)
rising pharmaceutical prices.
 
  Aging Population. The number of individuals over age 65 in the United States
grew 22% from approximately 26 million in 1980 to approximately 31 million in
1990 and is projected to increase an additional 12% to more than 35 million by
the year 2000. This age group suffers from a greater incidence of chronic
illnesses and disabilities than the rest of the population and is estimated to
account for approximately two-thirds of total health care expenditures in the
United States.
 
  Introduction of New Pharmaceuticals. Traditional research and development as
well as the advent of new research and production methods, such as
biotechnology, continue to generate new compounds that are more effective in
treating diseases. These compounds have been responsible for significant
increases in pharmaceutical sales. The Company believes that ongoing research
and development expenditures by the leading pharmaceutical manufacturers will
contribute to continued growth of the industry.
 
  Cost Containment Efforts. In response to rising health care costs,
governmental and private payors have adopted cost containment measures that
encourage the use of efficient drug therapies to prevent or treat diseases.
While national attention has been focused on the overall increase in aggregate
health care costs, the Company believes drug therapy has had a beneficial
impact on overall health care costs by reducing expensive surgeries and
prolonged hospital stays. Pharmaceuticals currently account for less than 11%
of overall health care costs, and manufacturers' emphasis on research and
development is expected to continue the introduction of cost-effective drug
therapies.
 
  Higher Concentration of Distribution Through Wholesalers. Over the past
decade, manufacturers of pharmaceuticals have significantly increased the
distribution of their products through wholesalers as the cost and complexity
of maintaining inventories and arranging for delivery of pharmaceutical
products has risen. Drug wholesalers offer their customers and suppliers more
efficient distribution and inventory management. As a result, from 1980
through 1997, the percentage of pharmaceutical sales through wholesale drug
distributors increased from approximately 46% to approximately 56%. Order
processing, inventory management and product delivery by wholesale drug
distributors allow manufacturers to allocate their resources to research and
development, manufacturing and marketing their products. Customers benefit
from this shift by having a single source of supply for a full line of
pharmaceutical products as well as lower inventory costs, more timely and
efficient
 
                                       3
<PAGE>
 
delivery, and improved purchasing and inventory information. In addition,
customers also benefit from the range of value-added programs developed by
wholesale drug distributors that are targeted to the specific needs of these
customers, which, in turn, reduce their costs and increase their operating
efficiencies.
 
  Pharmaceutical Price Increases By Drug Manufacturers. The Company believes
that price increases by pharmaceutical manufacturers will continue to equal or
exceed the overall Consumer Price Index. The Company believes that this
increase will be due in large part to the relatively inelastic demand in the
face of higher prices charged for patented drugs as manufacturers have
attempted to recoup costs associated with the development, clinical testing
and Food and Drug Administration ("FDA") approval of new products.
 
  At the same time that sales through the wholesale drug industry have grown,
the number of pharmaceutical wholesalers in the United States has decreased
from 139 at the end of 1980 to 43 as of September 1998. Industry analysts
expect this consolidation trend to continue, with the industry's largest
companies increasing their percentage of total industry sales.
 
OPERATIONS
 
  Decentralized Structure. The Company believes that operating economies of
scale exist principally at the distribution facility level. AmeriSource
currently operates 20 drug distribution facilities and three specialty
products distribution facilities, organized into six regions across the United
States. Unlike its more centralized competitors, the Company is structured as
an organization of locally managed profit centers. Management of each
distribution facility has fiscal responsibility for its facility. The
distribution facility's results, including earnings and achievement of asset
management goals, have a direct impact on management compensation at these
facilities. The distribution facilities utilize the Company's corporate staff
for marketing, financial, purchasing, legal and executive management resources
and corporate coordination of asset and working capital management. In the
fourth quarter of fiscal 1998, the Company began to centralize its data
processing, accounting, and contract administration functions, and also
intends to centralize the purchasing function. The Company believes that the
centralization of these administrative functions will result in future
efficiencies without affecting the Company's decentralized operations and
management.
 
  Sales and Marketing. The Company has an organization of over 225 sales
professionals organized regionally and specialized by customer segment.
Customer service representatives are located in each distribution facility in
order to respond to customer needs in a timely and effective manner. In
addition, a specially trained group of telemarketing representatives makes
regular contact with customers regarding special promotions. The Company's
corporate marketing department designs and develops the Company's array of
value-added programs and works with manufacturer suppliers to develop national
promotions. Tailored to specific customer classes, these programs can be
further customized at the distribution facility level to adapt to local market
conditions. The marketing department gathers and disseminates information to
each operating unit's purchasing and sales organization in order to enhance
their competitive effectiveness.
 
  Facilities. Each of the Company's distribution facilities carries an
inventory line necessary for its local market. The efficient distribution of
small orders is possible through the extensive use of computerization and
modern warehouse techniques. These include computerized warehouse product
location, routing and inventory replenishment systems, gravity-flow racking,
mechanized order selection and efficient truck loading and routing. The
Company typically delivers its products to its customers on a daily basis. It
utilizes a fleet of owned and leased vans and trucks and contract carriers.
Night picking operations in its distribution facilities have further reduced
delivery time. Orders are generally delivered in less than 24 hours.

  No single customer represented more than 5% of the Company's total operating
revenues during fiscal 1998, except that the federal government accounted for
approximately 16%. Excluding the federal government, the Company's top ten
customers represented approximately 17% of total operating revenues during
fiscal 1998. A profile of each customer class follows:
 
  . Hospitals and Managed Care Facilities. AmeriSource is one of the nation's
    top three distributors in serving the hospital and managed care market.
    Because hospitals and managed care facilities purchase large volumes of
    high-priced, easily handled pharmaceuticals, the Company benefits from
    quick turnover of both inventory and receivables and lower-than average
    operating expenses. Sales to hospitals and managed care facilities have
    grown at a compound rate of 17.4% from fiscal 1994 through fiscal 1998.
 
  . Independents. Independent community pharmacy owners provide the greatest
    opportunity for the Company's value-added services. The Company's sales
    to independent customers have risen at a compound rate of 22.9% from
    fiscal 1994 through fiscal 1998 due to the general growth of this
    customer class, the Company's recent acquisition activity, and the
    success of the Company's customized marketing and merchandising programs,
    such as its Family Pharmacy(R) program.
 
  . Chains. This class includes chain drug stores, including pharmacy
    departments of supermarkets and mass merchandisers. The Company's sales
    to chains have risen at a compound rate of 20.1% from fiscal 1994 through
    fiscal 1998. This growth rate reflects the results from the Company
    entering into new contracts with several drug store chains as well as the
    growth of its existing chain customers. Sales to chain drug stores
    decreased to 13% of operating revenues in the last quarter of fiscal 1998
    due to the termination of service contracts with two large warehousing
    chains.

  Suppliers. AmeriSource obtains pharmaceutical and other products from a
number of manufacturers, none of which accounts for more than approximately 8%
of its net sales in fiscal 1998. The five largest suppliers in fiscal 1998
accounted for approximately 29% of net sales. Historically, the Company has
not experienced difficulty in purchasing desired products from suppliers. The
Company has agreements with many of its suppliers which generally require the
Company to maintain an adequate quantity of a supplier's products in
inventory. The majority of contracts with suppliers are terminable upon 30
days notice by either party. The loss of certain suppliers could adversely
affect the Company's business if alternate sources of supply were unavailable.
The Company believes that its relationships with its suppliers are good.
 
  Management Information Systems. The Company has continually invested in
advanced management information systems and automated warehouse technology.
The Company's management information systems provide for, among other things,
electronic order entry by customers, invoice preparation and purchasing and
inventory tracking. As a result of electronic order entry, the cost of
receiving and processing orders has not increased as rapidly as sales volume.
The Company's customized systems strengthen customer relationships by allowing
the customer to lower its operating costs and by providing the basis for a
number of the value-added services the Company provides to its customers,
including marketing data, inventory replenishment, single-source billing,
computer price updates and price labels. In order to eliminate redundant
processes and related expenses, the Company began to centralize its management
information systems from six regional data processing facilities to one
corporate facility in July 1998. The centralization effort is proceeding on a
distribution facility-by-facility basis with completion expected by the end of
1999. AmeriSource believes that its management information systems are capable
of serving its needs for the foreseeable future.
 
COMPETITION
 
  The Company engages in the wholesale distribution of pharmaceuticals, health
and beauty aids and other products in a highly competitive environment. The
Company competes with numerous national and regional distributors, some of
which are larger and have greater financial resources than the Company. The
Company's national competitors include McKesson Corporation, Bergen Brunswig
Corporation, Cardinal Health, Inc., and Bindley Western Industries, Inc. In
addition, the Company competes with regional and local distributors, direct-
selling manufacturers, warehousing chain drug stores, and other specialty
distributors. Competitive factors include value-added service programs,
breadth of product line, price, service and delivery, credit terms, and
customer support. There can be no assurance that the Company will not
encounter increased competition in the future that could adversely affect the
Company's business. The drug wholesale industry continues to undergo
significant consolidation, with the number of wholesalers in the continental
United States declining from 139 at the end of 1980 to approximately 43 as of
September 1998.
 
EMPLOYEES
 
  As of September 30, 1998, the Company employed approximately 3,200 persons,
of which approximately 3,000 were full-time employees. Approximately 11% of
full and part-time employees are covered by collective bargaining agreements.
The Company believes that its relationship with its employees is good.
 
REGULATORY MATTERS
 
  The United States Drug Enforcement Administration and the Food and Drug
Administration and various state boards of pharmacy regulate the distribution
of pharmaceutical products and controlled substances, requiring wholesale
distributors of these substances to register for permits and to meet various
security and operating standards. As a wholesale distributor of
pharmaceuticals and certain medical/surgical products, the Company is subject
to these regulations. The Company has received all necessary regulatory
approvals and believes that it is in substantial compliance with all
applicable wholesale distribution requirements.
 
  The Company is aware that at its former Charleston, South Carolina
distribution center there is evidence of residual soil contamination remaining
from the fertilizer manufacturing process operated on that site by third
parties over thirty years ago. The Company's environmental consulting firm
conducted a soil survey and a
 
                                       6
<PAGE>
 
groundwater study during fiscal 1994 and 1995. The results of the studies
indicate that there is lead on-site at levels requiring further investigation
and potential remediation. A preliminary engineering analysis was prepared by
outside consultants during the third quarter of fiscal 1994, and indicated
that, if both soil and groundwater remediation are required, the most likely
cost is estimated to be $4.1 million. Accordingly, a liability of $4.1 million
was recorded during fiscal 1994 to cover future consulting, legal and
remediation and ongoing monitoring costs. The Company is working with the
appropriate state and federal regulatory agencies regarding further tests and
potential site remediation. That negotiation, investigation and remediation
could take several years and the actual costs may differ from the liability
that has been recorded. The accrued liability ($3.8 million at September 30,
1998), which is reflected in other long-term liabilities on the Company's
consolidated balance sheet, is based on the present estimate of the extent of
contamination, choice of remedy, and enacted laws and regulations, including
remedial standards; however, changes in any of these could affect the
estimated liability. The Company is investigating the possibility of asserting
claims against responsible third parties for recovery of these costs. Whether
or not any recovery may be forthcoming is unknown at this time, although the
Company intends to vigorously pursue its rights and remedies.
 
ACQUISITIONS
 
  On September 22, 1997 the Company and McKesson Corporation signed a
definitive merger agreement which was subsequently approved by both companies'
shareholders on February 9, 1998. On March 9, 1998, the Federal Trade
Commission (FTC) filed a complaint in the United States District Court for the
District of Columbia seeking a preliminary injunction to halt the proposed
merger. On July 31, 1998, the District Court granted the FTC's request for an
injunction to halt the proposed merger. On August 7, 1998, the Company and
McKesson jointly terminated the merger agreement.
 
ITEM 2. PROPERTIES
 
  As of September 1998, the Company conducted its business from office and
operating unit facilities at 41 locations throughout the United States. In the
aggregate, the Company's operating units occupy approximately 2.4 million
square feet of office and warehouse space, of which approximately 872,000
square feet is owned and the balance is leased under lease agreements with
expiration dates ranging from 1998 to 2012. The Company's 20 drug distribution
facilities range in size from approximately 20,000 square feet to 218,200
square feet. Leased facilities are located in the following states: Alabama,
Arizona, California, Delaware, Florida, Idaho, Kentucky, Massachusetts,
Minnesota, New Jersey, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee,
Texas, Virginia and West Virginia. Owned facilities are located in the
following states: Alabama, Indiana, Kentucky, Maryland, Missouri, Ohio,
Tennessee and Virginia. The Company utilizes a fleet of owned and leased vans
and trucks, as well as contract carriers to deliver its products. The Company
believes that its properties are adequate to serve the Company's current and
anticipated needs without making capital expenditures materially higher than
historical levels.
 
ITEM 3. LEGAL PROCEEDINGS
 
  A former customer of the Company has alleged that the Company failed to
fulfill its obligations under the service contract between the Company and the
former customer. In connection with this claim, the former customer withheld
payment on $22 million of invoices. In response, the Company filed suit to
collect the outstanding amount. The former customer has countersued the
Company for an unspecified amount. The Company believes there is no merit to
this counterclaim and intends to aggressively pursue collection of the
outstanding amount. Because the Company is unable at this time to determine
the outcome of this matter, no provision for loss has been made.
 
  In November 1993, the Company was named a defendant, along with six other
wholesale distributors and twenty-four pharmaceutical manufacturers, in a
series of purported class action antitrust lawsuits brought by retail
pharmacies and alleging violations of various antitrust laws stemming from the
use of chargeback agreements. In addition, the Company and four other
wholesale distributors were added as defendants in a series of related
antitrust lawsuits brought by independent pharmacies and chain drug stores,
both of which opted out of the class cases. The Company also was named a
defendant in parallel suits filed in state courts in Minnesota, Alabama,
Tennessee and
 
                                       7
<PAGE>
 
Mississippi. The federal class actions were originally filed in the United
States District Court for the Southern District of New York, but were
transferred along with the individual and chain drug store cases to the United
States District Court for the Northern District of Illinois for consolidated
and coordinated pretrial proceedings. In essence, these lawsuits all claim
that the manufacturer and wholesaler defendants have combined, contracted and
conspired to fix the prices charged to retail pharmacies for prescription
brand name pharmaceuticals. Specifically, plaintiffs claim that the defendants
use "chargeback agreements" to give some institutional pharmacies discounts
that allegedly are not made available to retail drug stores. Plaintiffs seek
injunctive relief, treble damages, attorneys' fees and costs. In October 1994,
the Company entered into a Judgment Sharing Agreement with the other
wholesaler and pharmaceutical manufacturer defendants. Under the Judgment
Sharing Agreement: (a) the manufacturer defendants agreed to reimburse the
wholesaler defendants for litigation costs incurred, up to an aggregate of $9
million; and (b) if a judgment is entered against both manufacturers and
wholesalers, the total exposure for joint and several liability of the Company
is limited to the lesser of 1% of such judgment or $1 million. In addition,
the Company has released any claims which it might have had against the
manufacturers for the claims presented by the Plaintiffs in these lawsuits.
The Judgment Sharing Agreement covers the federal court litigation as well as
the cases which have been filed in various state courts.
 
  On April 4, 1996, the District Court granted the Company's motion for
summary judgment in the class case. Plaintiffs subsequently appealed the
Company's grant of summary judgment to the United States Court of Appeals for
the Seventh Circuit. On August 15, 1997, the Court of Appeals reversed the
District Court's order granting summary judgment in favor of the Company and
the other wholesalers. The Court of Appeals also denied the Company's petition
for rehearing. The Company and the other wholesalers filed a petition for a
writ of certiorari to the United States Supreme Court; the petition was
denied. Trial in the class case commenced in the United States District Court
for the Northern District of Illinois on September 23, 1998. After a ten-week
trial, the Court granted all of the defendants' motions for a directed verdict
and dismissed the claims the class plaintiffs had asserted against the Company
and the other wholesale distributors and the pharmaceutical manufacturers.
 
  On or about October 2, 1997, a group of retail chain drug stores and
individual pharmacies, both of which had opted out of the class cases, filed a
motion with the United States District Court for the Northern District of
Illinois seeking to add the Company and the other wholesale distributors as
defendants in their cases against the manufacturer defendants, which cases are
consolidated before the same judge who is presently presiding over the class
cases. This motion was granted and the Company and the other wholesale
distributors have been added as defendants in those cases as well. As a
result, the Company has been served with approximately 120 additional
complaints on behalf of approximately 4,000 pharmacies and chain retailers.
Discovery and motion practice is presently underway in all of these opt-out
cases. The Company believes it has meritorious defenses to the claims asserted
in these lawsuits and intends to vigorously defend itself in all of these
cases.
 
  AmeriSource has been named as a defendant in two lawsuits based upon alleged
injuries attributable to a category of products typically referred to as fen-
phen. AmeriSource did not manufacture these products; however, prior to an FDA
recall, AmeriSource did distribute these products from several of its vendors.
The Company believes that it is entitled to full indemnification by its
vendors with respect to these lawsuits and any other lawsuits involving these
products in which AmeriSource may be named in the future. The Company believes
that its insurance coverage and indemnification rights are adequate to cover
any losses, if they should occur.
 
  The Company is a party to various lawsuits arising in the ordinary course of
business; however, the Company does not believe that the outcome of these
lawsuits, individually or in the aggregate, will have a material adverse
effect on its business or financial condition. (See Note 10 to the
consolidated financial statements.)
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  A special meeting of the Company's stockholders was held on February 9,
1998, to consider and vote upon a proposal to approve the Agreement and Plan
of Merger dated September 22, 1997, as amended, by and among

ITEM 5. MARKET FOR REGISTRANTS' COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.
 
  Since May 27, 1996, the Company's Class A Common Stock has been traded on
the New York Stock Exchange under the trading symbol "AAS." Prior to May 27,
1996, the Company's Class A Common Stock was traded over-the-counter in the
National Market System of the National Association of Securities Dealers, Inc.
(Nasdaq symbol ASHC). As of December 1, 1998, there were 263 record holders of

  The Company's Class C Common Stock was held by 5 holders of record as of
December 1, 1998. The Class C Common Stock trades on a limited basis in the
over-the-counter market, and information concerning the historical trading
prices for the Class C Common Stock is not published by nationally-recognized
independent sources.
 
  The Company has not paid any cash dividends to its stockholders on any class
of its Common Stock, and anticipates that for the foreseeable future its
earnings will be retained for use in its business. Payment of dividends is
within the discretion of the Company's Board of Directors and will depend,
among other factors, upon the Company's earnings, financial condition and
capital requirements and the terms of the Company's financing agreements. A
credit agreement between the Company and a syndicate of senior lenders provides
a secured credit facility of $500 million, and restricts the Company's ability
to make dividend payments unless certain financial tests are met.

YEAR ENDED SEPTEMBER 30, 1998 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1997
 
  Operating revenues for the fiscal year ended September 30, 1998 increased
10% to $8.6 billion from $7.8 billion in fiscal 1997. During the fiscal year
ended September 30, 1998, sales to hospitals and managed care facilities
increased 9%, sales to independent drug store customers increased 14%, and
sales to the chain drug store customer group increased 4%, as compared with
the prior year. During the fiscal year ended September 30, 1998 sales to
hospitals and managed care facilities accounted for 47% of total operating
revenues, while sales to independent drug stores accounted for 34% and sales
to chain drug stores accounted for 19% of the total.
 
  The majority of the operating revenue growth in fiscal 1998 was due to the
growth of relationships with existing customers. Approximately one-fourth of
the increase relates to the impact of the Walker Drug Company, L.L.C. ("Walker
Drug Company") acquisition in March 1997. The rate of growth was less than in
the prior year due to the termination of service contracts with two major
warehousing chains and one large mail order customer during the third fiscal
quarter that collectively accounted for approximately $300 million of revenue
per quarter. Sales to chain drug stores decreased to 13% of operating revenues
in the fourth quarter of fiscal 1998 as a result of the service contract
terminations. The Company does not expect that future operating income will be
significantly affected as the lost customers generated lower than average
operating margins and the Company expects that it will be able to reduce
expenses in line with the loss of gross profit. Future operating revenues may
also be impacted by continued consolidations of customers and price
competition in the industry.
 
  Along with other companies in its industry, the Company has begun reporting
as revenue bulk shipments to customer warehouses, whereby the Company acts as
an intermediary in the ordering and subsequent delivery of pharmaceutical
products. All periods presented have been restated to reflect these bulk
shipments as revenue. Previously, only the service fees from these bulk
shipments were included in revenue. Due to the insignificant service fees
generated from these bulk shipments, fluctuations in volume have no
significant impact on operating margins.
 
  Gross profit of $421.3 million in fiscal 1998 increased by 9% compared to
fiscal 1997. As a percentage of operating revenues, the gross profit in fiscal
1998 was 4.91% as compared to 4.96% in the prior fiscal year. The decline in
gross profit percentage was due to a reduction in selling margin percentage
due to strong competition in the industry as well as continued customer
consolidation offset in part by an increase in inventory appreciation profits.
Gross profit may continue to be impacted by price competition, changes in
customer and product mix, and distribution center performance.
 
  On September 22, 1997, the Company and McKesson Corporation signed a
definitive merger agreement which was subsequently approved by both companies'
shareholders on February 9, 1998. On July 31, 1998 the United States District
Court for the District of Columbia granted the Federal Trade Commission's
request for an injunction to halt the proposed merger. On August 7, 1998, the
Company and McKesson jointly terminated the merger agreement. Merger related
costs consisting of professional fees and stay-put bonuses totaling $18.4
million were expensed in the fourth quarter of fiscal 1998 as a result of the
termination of the merger agreement.
 
  In the fourth quarter of fiscal 1998 the Company began to centralize its
data processing, accounting, contract administration, and purchasing
functions, reorganize its pharmaceutical distribution facilities into six
regions, and
 
                                      11

consolidate one pharmaceutical distribution facility into another facility.
These initiatives are expected to be completed by the end of 1999 and when
completed are expected to provide annual cost savings of $5 to $6 million. A
charge of $8.3 million was recognized in the fourth quarter of fiscal 1998
related to this effort, and included severance of $3.3 million for
approximately 350 administrative and warehouse personnel and asset write-downs
and lease cancellation costs of $5.0 million primarily consisting of owned and
leased data processing assets to be abandoned after the consolidation dates of
the affected data processing centers.
 
  In the third quarter of fiscal 1997, the Company commenced cost reduction
plans to consolidate three of its pharmaceutical distribution facilities into
other existing facilities and to restructure its sales force. These cost
reduction initiatives resulted in a $6.4 million charge in the third fiscal
quarter of 1997. In addition the Company incurred charges of $5.2 million
related to the retirement of its former President and CEO as well as other
executive terminations. The $6.4 million charge included $1.8 million for the
severance of approximately 240 warehouse and sales personnel and $4.6 million
of asset write-downs and lease cancellation costs primarily for buildings,
warehouse and computer equipment and other assets to be disposed of related to
the facility consolidations. The fiscal 1997 cost reduction initiatives were
completed in early fiscal 1998.
 
  Selling and administrative expenses and depreciation increased by $13.3
million or 5% in fiscal 1998 compared with the prior fiscal year, and as a
percentage of operating revenues, were 3.13% in fiscal 1998 and 3.27% in
fiscal 1997. The increase in selling and administrative expenses and
depreciation for the year is primarily due to the impact of a full year of
expenses from the February 1997 acquisition of Walker Drug Company. The
decrease in the expense to operating revenue ratio for the year was primarily
due to benefits resulting from the fiscal 1997 cost reduction initiatives
discussed above as well as the shift in customer mix resulting from the
termination of service contracts with the two large warehousing chain
customers.
 
  Operating income of $124.9 million for the year ended September 30, 1998
increased by 4% from the prior year. The Company's operating margin decreased
to 1.46% in fiscal 1998 from 1.53% in fiscal 1997. This decrease in operating
margin is due to the $18.4 million of merger costs described above. In
addition, both years have been impacted by the charges related to facility
consolidations and employee severance discussed above.
 
  Interest expense of $42.1 million in fiscal 1998 represents an increase of
1% compared to the prior year as average borrowings for the year increased by
6% offset in part by a 50 basis point step-down in the interest rate under the
Company's revolving credit facility during fiscal 1998 as a result of
attaining certain financial ratios under the facility. Average borrowings
during the year ended September 30, 1998 were $639 million as compared to
average borrowings of $602 million in the prior fiscal year.
 
  Income tax expense of $32.3 million in fiscal 1998 was based on an effective
tax rate of 39.0% versus 39.2% in the prior year. The decrease in the rate was
due to a reduction in the effective state and local income tax rate.
 
  Income before extraordinary items increased to $50.5 million in fiscal 1998
from $47.4 million in fiscal 1997. Income before extraordinary items per
share-assuming dilution was $2.08 in fiscal 1998, a 6% increase over fiscal
1997. The effect of the merger costs and charges related to facility closings
and employee severance are included in these amounts.
 
  In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128, Earnings Per Share. SFAS No.
128 replaced the previously reported primary and fully diluted earnings per
share with basic and diluted earnings per share. Unlike primary earnings per
share, basic earnings per share excludes any dilutive effects of options,
warrants, and convertible securities. Earnings per share-assuming dilution is
very similar to the previously reported fully diluted earnings per share. All
earnings per share amounts for all periods presented prior to fiscal 1998 have
been restated to conform to the SFAS No. 128 requirements.
 
YEAR ENDED SEPTEMBER 30, 1997 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1996
 
  Operating revenues for the fiscal year ended September 30, 1997 increased
41% to $7.8 billion from $5.6 billion in fiscal 1996. The year-to-year
operating revenue gains reflect increases across all customer groups and all
 
                                      12
<PAGE>
 
geographic regions. The acquisitions of Walker Drug Company in March 1997, and
Gulf Distribution, Inc. in February 1996, contributed 9% of the 41% increase
in revenues for the fiscal year. During the fiscal year ended September 30,
1997, sales to hospitals and managed care facilities increased 39%, sales to
independent drug store customers increased 43%, and sales to the chain drug
store customer group increased 43%, as compared with the prior year.
Approximately 28% of the hospital and managed care revenue increase was due to
the addition of one large mail order pharmacy customer. During the fiscal year
ended September 30, 1997, sales to hospitals and managed care facilities
accounted for 47% of total revenues, while sales to independent drug stores
accounted for 33% and sales to chain drug stores accounted for 20% of the
total.
 
  Gross profit of $387.5 million in fiscal 1997 increased by 28% over fiscal
1996 due to the increase in operating revenues. As a percentage of operating
revenues, the gross profit in fiscal 1997 was 4.96% as compared to 5.45% in
the prior fiscal year. The majority of the decline in gross profit percentage
was due to a reduction in selling margin percentage resulting from continuing
price competition throughout the industry and the higher-than average growth
of the Company's largest customers. Approximately 30% of the decline in gross
profit percentage from the prior fiscal year was due to the addition of a
large ($290 million in annualized revenues) mail order pharmacy customer at a
gross profit percentage significantly lower than normal percentages and a
performance shortfall in one of the Company's distribution centers. Gross
profit may continue to be impacted by price competition, changes in customer
and product mix, and distribution center performance.
 
  Selling and administrative expenses and depreciation, increased by $51.0
million or 25% in fiscal 1997 compared with the prior fiscal year, and as a
percentage of operating revenues, were 3.27% in fiscal 1997 and 3.68% in
fiscal 1996. The increase in expenses was due to increased delivery and
warehouse expense associated with the significant revenue increase. The
decrease as a percentage of revenue in fiscal 1997 is primarily due to
improved economies of scale at the Company's established and newer locations
and the low service cost associated with the large mail order customer which
has offset higher-than anticipated integration costs of the Company's Orlando,
Florida facility.
 
  Operating income of $119.6 million in fiscal 1997 increased by 22% from the
prior year. Included in operating income is the effect of the $11.6 million of
facility consolidations and employee severance in fiscal 1997 and a $10.9
million cumulative non-cash charge to costs of goods sold in fiscal 1996. The
Company's operating margin declined to 1.53% in fiscal 1997 from 1.76% in
fiscal 1996. The decline is due to the decrease in gross profit percentage
discussed above, offset in part by reduced selling and administrative expenses
as a percentage of operating revenues.
 
  Interest expense of $41.6 million in fiscal 1997 represents an increase of
16% compared to the prior fiscal year. The increase over the prior year was
due to increased borrowings to fund the 41% revenue increase and the purchase
of Walker Drug Company in March 1997. Average borrowings during the fiscal
year ended September 30, 1997 were $602 million as compared to average
borrowings of $479 million in the prior fiscal year. The increased average
indebtedness was offset in part by reduced borrowing rates compared to the
prior year due to the redemption of the remaining $74.3 million of 11 1/4%
senior debentures in the third quarter of fiscal 1996 and rate reductions
under the Company's revolving credit facility and receivables securitization
financing ("Receivables Program").
 
  Income tax expense of $30.6 million in fiscal 1997 was based on an annual
effective rate of 39.2% versus 31.1% in fiscal 1996. The fiscal 1996 rate was
reduced by 11.5% due to a favorable settlement of an Internal Revenue Service
audit of fiscal years 1987-1991. The extraordinary charge in fiscal 1997 of
$2.0 million, net of a tax benefit of $1.2 million, relates to the write-off
of unamortized deferred financing fees related to the retirement of the prior
$380 million revolving credit facility.
 
  Income before extraordinary items increased to $47.4 million in fiscal 1997
from $42.7 million in fiscal 1996 and income before extraordinary items per
share-assuming dilution was $1.97, a 6% increase over fiscal 1996.

LIQUIDITY AND CAPITAL RESOURCES
 
  During the year ended September 30, 1998, the Company's operating activities
generated $125.8 million in cash primarily due to a decrease in accounts
receivable of $70.4 million. The reduction in accounts receivable was due to a
combination of a 2 day reduction in days sales outstanding due to improved
collection efforts and term negotiations as well as the impact of the loss of
the three major customers discussed above. As a result of the reduction in
accounts receivable, the collateral base for the receivables securitization
facility as of September 30, 1998 was less than the $299.9 million of fixed
certificates outstanding. Therefore, cash was deposited in the master trust to
supplement the collateral base, which resulted in the increase in restricted
cash at September 30, 1998. The provision for deferred income taxes increased
operating cash flow by $19.2 million primarily due to an increase in deferred
tax liabilities related to inventory. A decrease in merchandise inventory of
$147.6 million was offset by a related decrease of $161.8 million in accounts
payable and accrued expenses. These decreases were also impacted by the
termination of service contracts of the three large customers as well as the
reversal of the prior year end build-up of inventory related to the Company's
expansion of its Thorofare, New Jersey distribution facility. Operating cash
uses during the year ended September 30, 1998 included $44.4 million in
interest payments and $16.0 million in income tax payments. In addition, in
fiscal 1998, the Company paid a total of $5.5 million of severance and $0.6
million of lease cancellation costs and other related to its fiscal 1998 and
1997 cost reduction plans discussed above. Severance accruals of $4.3 million
and remaining lease obligations of $3.0 million at September 30, 1998 are
included in accrued expenses and other.
 
  In fiscal 1997, the Company's operating activities used $9.3 million of cash
as increases in merchandise inventories of $271.8 million and accounts
receivable of $76.2 million were offset in part by the $274.9 million increase
in accounts payable and accrued expenses. These increases were caused by the
working capital requirements of the Company's significant revenue growth
during fiscal 1997, as well as the year end temporary build-up of inventory
and accounts payable related to the Company's expansion of its Thorofare, New
Jersey facility.
 
  Capital expenditures for the year ended September 30, 1998 were $10.4
million and relate principally to investments in warehouse improvements,
information technology and warehouse automation. These expenditures decreased
from prior years due to delays in starting certain projects due to the
proposed McKesson merger. Expenditures for similar purposes of approximately
$18 to $20 million are expected in fiscal 1999.
 
  Cash used by financing activities during fiscal 1998 represents net
repayments of the Company's revolving credit facility from cash generated by
operations. In fiscal 1997, net borrowings of $148.7 million primarily funded
the acquisition of Walker Drug Company in March 1997. At September 30, 1998,
borrowings under the Company's $500 million revolving credit facility were
$145.0 million (at an average interest rate of 6.9%) and borrowings under the
$375 million receivable securitization financings were $299.9 million (at an
average interest rate of 5.9%). The revolving credit facility expires in
January 2002 and provides for interest rates ranging from LIBOR plus 25 basis
points to LIBOR plus 125 basis points based upon certain financial ratios. The
receivable securitization facility represents a financing vehicle utilized by
the Company because of the availability of attractive interest rates relative
to traditional financing sources. The Company securitizes its trade accounts
and notes receivable, which are generally non-interest bearing, in
transactions that do not qualify as sales transactions under SFAS No. 125. The
details of the receivable securitization financing program are summarized in
Note 4 to the consolidated financial statements. In December 1998, the Company
entered into a short-term supplemental $100 million revolving credit agreement
with substantially the same terms as the Credit Agreement. This agreement
expires March 31, 1999 and is intended to fund seasonal inventory purchases if
necessary.
 
  The Company's primary exposure to market risk consists of changes in
interest rates on borrowings. An increase in interest rates would adversely
affect the Company's operating results and the cash flow available after debt
service to fund operations and expansion and, if permitted to do so under its
revolving credit facility, to pay dividends on its capital stock. The Company
enters into interest rate protection agreements to hedge the exposure to
increasing interest rates with respect to its long-term debt agreements. The
Company provides protection to meet actual exposures and does not speculate in
derivatives. The Company is required by its Credit Agreement
 
                                      14
<PAGE>
 
to maintain interest rate cap protection on a minimum of $112.5 million
through January 1999 and has interest rate cap agreements expiring in May
1999, which provide protection on $115 million of its long-term borrowings.
For every $100 million of unhedged variable rate debt a 75 basis point
increase in interest rates would increase the Company's annual interest rate
expense by approximately $0.75 million.
 
  The Company's operating results have generated sufficient cash flow which,
together with borrowings under its debt agreements and credit terms from
suppliers, have provided sufficient capital resources to finance working
capital and cash operating requirements, fund capital expenditures, and
interest currently payable on outstanding debt. The Company's primary ongoing
cash requirements will be to fund payment of interest on indebtedness, finance
working capital, and fund capital expenditures and routine growth and
expansion through new business opportunities. Future cash flows from
operations and borrowings are expected to be sufficient to fund the Company's
ongoing cash requirements.
 
  A former customer of the Company has alleged that the Company failed to
fulfill its obligations under the service contract between the Company and the
former customer. In connection with this claim, the former customer withheld
payment on $22 million of invoices. In response, the Company filed suit to
collect the outstanding amount. The former customer has countersued the
Company for an unspecified amount. The Company believes that there is no merit
to this counterclaim and intends to aggressively pursue collection of the
outstanding amount. Because the Company is unable at this time to determine
the outcome of this matter, no provision for loss has been made in the
financial statements.
 
  The Company is subject to certain contingencies pursuant to environmental
laws and regulations at one of its former distribution centers that may
require remediation efforts. In fiscal 1994, the Company accrued a liability
of $4.1 million to cover future consulting, legal, remediation, and ongoing
monitoring costs. The accrued liability ($3.8 million at September 30, 1998),
which is reflected in other long-term liabilities on the accompanying
consolidated balance sheet, is based on an estimate of the extent of
contamination and choice of remedy, existing technology, and presently enacted
laws and regulation; however, changes in remediation standards, improvements
in cleanup technology, and discovery of additional information concerning the
site could affect the estimated liability in the future. The Company is
investigating the possibility of asserting claims against responsible parties
for recovery of these costs. Whether or not any recovery may be forthcoming is
unknown at this time.
 
GENERAL DESCRIPTION OF THE YEAR 2000 ISSUE AND THE NATURE AND EFFECTS OF THE
YEAR 2000 ON INFORMATION TECHNOLOGY (IT) AND NON-IT SYSTEMS
 
  The Year 2000 Issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the
Company's computer programs that have date-sensitive software or embedded
chips may recognize a date using "00" as the year 1900 rather than the year
2000. This could result in a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary
inability to process transactions, send invoices, or engage in similar normal
business practices.
 
  The Company began addressing the Year 2000 Issue in 1995 on a decentralized
basis at each of its regional data processing centers. In 1997, the Company
began monitoring progress on a corporate level and a formal Year 2000
committee, reporting to senior management, was established in early 1998 to
coordinate and monitor the Year 2000 Issue on an enterprise-wide basis. Based
on assessments made since 1995, the Company determined that modifications to
or in limited cases replacement of computer software and hardware was
necessary to enable those systems to operate properly after December 31, 1999.
The Company presently believes that with modifications to and replacement of
existing software and hardware, the Year 2000 Issue can be mitigated. However,
if such modifications and replacements are not made, or are not completed
timely, the Year 2000 Issue can have a material impact on the operations of
the Company.
 
  In the fourth quarter of fiscal 1998, the Company announced plans to
consolidate its data processing from its regional facilities to one corporate
facility by the end of 1999. However, the Company's plan to resolve the
 
                                      15
<PAGE>
 
Year 2000 Issue described below is not dependent on the timely completion of
the Company's consolidation efforts.
 
  The Company's plan to resolve the Year 2000 Issue involves the following
four phases: assessment, remediation, testing, and implementation. To date,
the Company has completed its assessment of all systems that could be
significantly affected by the Year 2000. The assessment indicated that most of
the Company's significant information technology systems could be affected,
particularly the Company's warehouse and distribution operating and accounting
systems. The assessment also indicated that software and hardware (embedded
chips) used in warehouse automation, scanning, and ordering as well as other
equipment used in the distribution process (operating equipment) are also at
risk. Because the Company is a distributor of pharmaceuticals, the Company's
products are not at risk.
 
STATUS OF PROGRESS IN BECOMING YEAR 2000 COMPLIANT, INCLUDING TIMETABLE FOR
COMPLETION OF EACH REMAINING PHASE
 
  The following estimates of completion percentages and dates are based on the
Company's best estimates. However, there can be no guarantee that these dates
can be achieved and actual results may differ. For its information technology
exposures, to date the Company is approximately 95% complete on the
remediation phase and expects to be completed with its software reprogramming
and replacement no later than March 31, 1999. Once software is reprogrammed or
replaced for a system, the Company begins testing and implementation. These
phases run concurrently for different systems. To date, the Company has
completed 90% of its testing and has implemented 85% of its remediated
systems. Completion of the testing phase for all significant operating systems
is expected by March 31, 1999, with all remediated systems fully tested and
implemented by June 30, 1999.
 
  The remediation of operating equipment with embedded chips or software is
approximately 95% complete and is expected to be completed by March 31, 1999.
Testing of the affected equipment is approximately 90% complete and
implementation of affected equipment is 85% complete. Testing is expected to
be complete by March 31, 1999, and implementation by June 30, 1999.
 
NATURE AND LEVEL OF IMPORTANCE OF THIRD PARTIES AND THEIR EXPOSURE TO THE YEAR
2000
 
  Many of the Company's customers order products from the Company using
ECHO(R), the Company's proprietary software system. ECHO(R) was developed in-
house and has been Year 2000 compliant from its inception. The Company also
issues the majority of its purchase orders to vendors through the use of
Electronic Data Interchange ("EDI"). The Company is approximately 50% complete
with its remediation efforts relating to EDI software and expects to be
complete by March 31, 1999. Testing and implementation of this software is
expected to be completed by June 30, 1999.
 
  The Company is planning to survey its significant customers and vendors as
to their Year 2000 compliance in February and March, 1999. Based on the nature
of their responses, the Company will develop contingency plans as appropriate.
However, the Company has no means of assuring that external customers and
vendors will be Year 2000 compliant. The inability of these third parties to
complete their Year 2000 resolution process in a timely fashion could
materially impact the Company.
 
COSTS
 
  The Company has utilized and will continue to utilize both internal and
external resources to reprogram, or replace, test, and implement the software
and operating equipment for Year 2000 modifications. Many of the program fixes
were completed in conjunction with other projects and had little incremental
cost. The Company estimates that incremental costs relating to Year 2000
projects to date approximate $2 million. These costs have been expensed as
incurred. The Company expects to spend less than $1 million on Year 2000
projects in fiscal 1999. Year 2000 costs are difficult to estimate accurately
and the projected cost could change due to unanticipated technical
difficulties, project delays, and third party non-compliance, among other
things.
 
                                      16

RISKS
 
  Management of the Company believes that it has an effective program in place
to resolve the Year 2000 Issue in a timely manner. As noted above, the Company
has not yet completed all necessary phases of its Year 2000 plan. Because of
the range of possible issues and the large number of variables involved, it is
impossible to quantify the potential cost of problems should the Company or
its trading partners not properly complete their Year 2000 plans and become
Year 2000 compliant. Such costs and any failure of compliance efforts could
have a material adverse effect on the Company. The Company believes that the
most likely risks of serious Year 2000 business disruption are external in
nature, including continuity of utility, telecommunication and transportation
services, and the potential failure of the Company's customers due to their
own non-compliance or the non-compliance of their business partners. In the
event the Company does not properly complete its Year 2000 efforts or is
affected by the disruption of outside services, the Company could be unable to
take orders, distribute goods, invoice customers or collect payments. In
addition, disruptions in the economy generally resulting from Year 2000 could
have a material adverse effect on the Company. The Company could be subject to
litigation for computer systems failure. The amount of potential liability and
lost revenue cannot be reasonably estimated at this time.
 
CONTINGENCY PLANS
 
  The Company is currently in process of developing contingency plans to
address the above Year 2000 risks as necessary. The Company plans to evaluate
the status of completion of its Year 2000 efforts by March 31, 1999 and to
determine what contingency plans are necessary at that time. In the normal
course of business, the Company has contingency plans for disruption of
business events and intends to augment those plans with specific Year 2000
considerations.
 
RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS
 
  In fiscal 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 130 "Reporting Comprehensive Income," which requires that an
enterprise report, by major component and as a single total, the change in its
net assets during the period from nonowner sources and SFAS No. 131
"Disclosures about Segments of an Enterprise and Related Information," which
establishes annual and interim reporting standards for an enterprise's
operating segments and related disclosures about its products, services,
geographic areas, and major customers. In fiscal 1998, the FASB issued SFAS
No. 132 "Employers' Disclosures about Pensions and Other Postretirement
Benefits," which standardizes the disclosure requirements for pensions and
other postretirement benefits and expands disclosures on changes in benefit
obligations and fair values of plan assets. These statements are effective for
fiscal years beginning after December 15, 1997. Also, in fiscal 1998, the FASB
issued SFAS No. 133 "Accounting for Derivative Instruments and Hedging
Activities," which requires companies to recognize all derivatives as either
assets or liabilities in the balance sheet and measure such instruments at
fair value. SFAS No. 133 is effective for fiscal years beginning after June
15, 1999. Adoption of these statements will not impact the Company's
consolidated financial position, results of operations or cash flows, and any
effect will be limited to the form and content of its disclosures.
 
FORWARD LOOKING STATEMENTS
 
  Certain information in this Management's Discussion and Analysis of
Financial Condition and Results of Operations contains forward-looking
statements as such term is defined in Section 27A of the Securities Act and
Section 21E of the Exchange Act. Certain factors such as changes in interest
rates, competitive pressures, customer and product mix, inventory investment
buying opportunities, regulatory changes, the Year 2000 Issue, and capital
markets could cause actual results to differ materially from those in forward-
looking statements.

  We have audited the accompanying consolidated balance sheets of AmeriSource
Health Corporation and subsidiaries as of September 30, 1998 and 1997, and the
related consolidated statements of operations, changes in stockholders'
equity, and cash flows for each of the three years in the period ended
September 30, 1998. Our audits also included the financial statement schedules
listed in the Index at Item 14(a). These financial statements and schedules
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements and 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, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of AmeriSource Health Corporation and subsidiaries at September 30, 1998 and
1997 and the consolidated results of their operations and their cash flows for
each of the three years in the period ended September 30, 1998, in conformity
with generally accepted accounting principles. Also, in our opinion, the
related financial statement schedules, when considered in relation to the
basic financial statements taken as a whole, present fairly in all material
respects the information set forth therein.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                              SEPTEMBER 30, 1998
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Presentation
 
  The accompanying consolidated financial statements include the accounts of
AmeriSource Health Corporation and its wholly-owned subsidiaries (the
"Company") as of the dates and for the periods indicated. All intercompany
transactions and balances have been eliminated in consolidation.
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements and
accompanying notes. Actual amounts may differ from these estimated amounts.
 
 Business
 
  The Company is a wholesale distributor of pharmaceuticals and related health
care products within the United States.
 
 Cash Equivalents
 
  The Company classifies highly liquid investments with original maturities of
three months or less at date of purchase as cash equivalents.
 
 Concentrations of Credit Risk
 
  The Company sells its merchandise inventories to a large number of customers
in the health care industry, including independent drug stores, chain drug
stores, hospitals, mass merchandisers, clinics, and nursing homes. The
Company's trade accounts receivable are exposed to credit risk, but the risk
is limited due to the diversity of the customer base and the customer base's
wide geographic dispersion. The Company performs ongoing credit evaluations of
its customers' financial condition. The Company maintains reserves for
potential bad debt losses and such bad debt losses have been within the
Company's expectations.
 
  The Company maintains cash balances at several large creditworthy banks
located in the United States. Accounts at each institution are insured by the
Federal Deposit Insurance Corporation up to $100,000. The Company does not
believe there is significant credit risk related to its cash balances.
 
 Merchandise Inventories
 
  Inventories are stated at the lower of cost or market. Cost is determined
using the last-in, first-out (LIFO) method, which results in a matching of
current costs and revenues. If the first-in, first-out (FIFO) method of
valuation had been used for determining costs, inventories would have been
approximately $96.1 million and $100.7 million higher than the amounts
reported at September 30, 1998 and 1997, respectively.
 
 Property and Equipment
 
  Property and equipment are stated at cost and depreciated on the straight-
line method over the estimated useful lives of the assets which range from
three to forty years.
 
 Revenue Recognition
 
  The Company recognizes revenues when products are delivered to customers.
The Company also acts as an intermediary in the bulk shipment of
pharmaceuticals from manufacturers to customers' warehouses.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
All periods presented have been restated to include these bulk shipments in
revenues and cost of goods sold. Previously only the service fees from these
bulk shipments had been included in revenues.
 
 Stock-Based Compensation
 
  The Company follows Accounting Principles Board ("APB") Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations in
accounting for its employee stock-based compensation (See Note 7).
 
 Earnings Per Share and Share Data
 
  In fiscal 1998, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 128, "Earnings Per Share." SFAS No. 128 replaced the
previously reported primary and fully diluted earnings per share with basic
and diluted earnings per share. Unlike primary earnings per share, basic
earnings per share excludes any dilutive effects of options, warrants, and
convertible securities. Earnings per share--assuming dilution is very similar
to the previously reported fully diluted earnings per share. All share and per
share amounts for all periods presented prior to fiscal 1998 have been
restated in accordance with the provision of SFAS No. 128.
 
  Earnings per share is computed on the basis of the weighted average number
of shares of common stock outstanding during the periods presented
(23,953,000, 23,720,000 and 22,687,000 for fiscal years 1998, 1997, and 1996,
respectively). Earnings per share--assuming dilution is computed on the basis
of the weighted average numbers of shares outstanding during the period plus
the dilutive effect of stock options (322,000, 340,000 and 209,000, for fiscal
years 1998, 1997 and 1996, respectively).
 
 Recently Issued Financial Accounting Standards
 
  In fiscal 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 130 "Reporting Comprehensive Income," which requires that an
enterprise report, by major component and as a single total, the change in its
net assets during the period from nonowner sources and SFAS No. 131
"Disclosures about Segments of an Enterprise and Related Information," which
establishes annual and interim reporting standards for an enterprise's
operating segments and related disclosures about its products, services,
geographic areas, and major customers. In fiscal 1998, the FASB issued SFAS
No. 132 "Employers' Disclosures about Pensions and Other Postretirement
Benefits," which standardizes the disclosure requirements for pensions and
other postretirement benefits and expands disclosures on changes in benefit
obligations and fair values of plan assets. These statements are effective for
fiscal years beginning after December 15, 1997. Also, in fiscal 1998, the FASB
issued SFAS No. 133 "Accounting for Derivative Instruments and Hedging
Activities," which requires companies to recognize all derivatives as either
assets or liabilities in the balance sheet and measure such instruments at
fair value. SFAS No. 133 is effective for fiscal years beginning after June
15, 1999. Adoption of these statements will not impact the Company's
consolidated financial position, results of operations or cash flows, and any
effect will be limited to the form and content of its disclosures.
 
NOTE 2--ACQUISITIONS
 
  During fiscal 1997, the Company acquired all of the equity interests of
Walker Drug Company, L.L.C. in a cash transaction. Walker Drug Company, L.L.C.
is a wholesale pharmaceutical distributor based in Pelham, Alabama, which had
annual revenues of approximately $800 million. During fiscal 1996, the Company
acquired all of the stock of Gulf Distribution, Inc., a Miami, Florida-based
wholesale pharmaceutical distributor, which had annual revenues of
approximately $180 million, and substantially all of the assets of The
Diabetic Shoppe, Inc., a Wisconsin-based provider of diabetic disease
management programs to retail pharmacies.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
NOTE 2--ACQUISITIONS--(CONTINUED)
 
  The aggregate purchase price for these acquisitions, including the
assumption of long-term debt, was approximately $138.7 million and $29.5
million in fiscal 1997 and 1996, respectively, and they were financed by
borrowings under the Company's revolving credit facility. These acquisitions
were accounted for by the purchase method and their results of operations are
included in the financial statements from their dates of acquisition. The
excess of purchase price over net assets acquired of $27.4 million and $8.2
million in fiscal 1997 and 1996, respectively, has been allocated to goodwill
(which is included in other assets) and is being amortized on a straight-line
basis over 40 years.
 
  The following unaudited table (in thousands, except per share data) reflects
financial results on a pro forma basis, assuming the fiscal 1997 and 1996
acquisitions had occurred at the beginning of the periods presented. Pro forma
adjustments include: increased amortization for the cost over net assets
acquired; increased interest expense associated with financing the
acquisitions; and related income tax effects. Cost savings from combining the
operations are not reflected.

  In fiscal 1995, the Company received notices from the Internal Revenue
Service asserting deficiencies in federal corporate income taxes for the
Company's taxable years 1987 through 1991. The proposed adjustments indicated
a net increase to taxable income for these years of approximately $24 million
and related principally to the deductibility of costs incurred with respect to
the leveraged buyout transaction which occurred in 1988. Legislation enacted
in August 1996, eliminated approximately $20 million of the proposed
adjustments relating to the deductibility of costs incurred with respect to
the leveraged buyout transaction. In addition, the Company reached a
settlement with the Appeals Office of the Internal Revenue Service on all
remaining audit issues, resulting in an assessment of $2.1 million, including
interest. As a result of the settlement, the Company reduced accrued income
taxes and income tax expense by $7.1 million in fiscal 1996.
 
  Deferred income taxes reflect the future tax consequences of differences
between the tax bases of assets and liabilities and their financial reporting
amounts. Significant components of the Company's deferred tax liabilities
(assets) are as follows (in thousands):

losses expiring in 5 to 15 years. As of September 30, 1998 and 1997, the
Company had $31.0 million and $3.9 million, respectively, of alternative
minimum tax credit carryforwards.
 
  Income tax payments amounted to $16.0 million, $18.7 million, and $6.9
million in the fiscal years ended September 30, 1998, 1997, and 1996,
respectively.
 
NOTE 4--LONG-TERM DEBT
 
 Receivable Securitization Financing
 
  The Company sells substantially all of its trade accounts and notes
receivable (the "Receivables") to AmeriSource Receivables Corporation ("ARC"),
a special-purpose, wholly-owned subsidiary, pursuant to a trade receivables
securitization program (the "Receivables Program"). Additionally, the Company
has a Receivables Purchase Agreement with ARC, whereby ARC purchases on a
continuous basis Receivables originated by the Company. Pursuant to the
Receivables Program, ARC transfers such Receivables to a master trust in
exchange for, among other things, certain trade receivables-backed
certificates (the "Certificates"). During the term of the Receivables Program,
the cash generated by collections on the Receivables is used to purchase,
among other things, additional Receivables originated by the Company. The
Company accounts for the Receivables Program as a financing transaction in its
consolidated financial statements.
 
  Pursuant to the Receivables Program in fiscal 1995, the Company issued: (i)
$175 million of Floating Rate Class A Trade Receivables Participation
Certificates ("Class A Certificates") and (ii) $35 million of Floating Rate
Class B Trade Receivables Participation Certificates ("Class B Certificates"),
which represent fractional undivided interests in the Receivables and other
assets of the master trust. The Class A Certificates bear interest at one
month LIBOR plus .35% and the Class B Certificates, which are subordinated to
the Class A Certificates, bear interest at one month LIBOR plus .70%. In
fiscal 1997, the Company issued an additional $90 million of Floating Rate
Class A Trade Receivables Participation Certificates Series 1997-1 (the
"Series 1997-1 Certificates"). The Series 1997-1 Certificates bear interest at
one month LIBOR plus .20%. The Class A, Class B and Series 1997-1 Certificates
each have a five-year term. In addition, the Company issued Floating Rate
Revolving Principal Trade Receivables Participation Certificates ("Revolving
Certificates"), pursuant to which investors may purchase up to $75 million of
interests in the master trust, which Certificates will bear interest, at the
Company's option, at either LIBOR plus .35% or the federal funds rate plus
1.00%. The Revolving Certificates rank pari passu in right of payment with the
Class A Certificates. There were no Revolving Certificates outstanding at
September 30, 1998 and 1997. Fees of $0.7 million and $4.6 million incurred in
fiscal 1997 and fiscal 1995 in connection with establishing the Receivables
Program have been deferred and are being amortized on a straight-line basis
over a period of five years. Class A Certificates of $175 million principal
amount (at an interest rate of 5.9%), Class B Certificates of $35 million
principal amount (at an interest rate of 6.3%) and Series 1997-1 Certificates
of $90 million principal amount (at an interest rate of 5.8%) were outstanding
under the Receivables Program at September 30, 1998. The Company is required
to pay a commitment fee of 1/4 of 1% per annum on the unused portion of the
Revolving Certificates. Restricted cash of $37.0 million and $8.9 million at
September 30, 1998 and 1997, represents amounts temporarily deposited in the
master trust which amounts are designated for specific purposes pursuant to
the Receivables Program, including cash deposited by the Company to supplement
the receivable collateral base, if that base is not sufficient to support the
Class A, Class B, and Series 1997-1 Certificates.
 
 Revolving Credit Agreement
 
  In January 1997, the Company entered into a new revolving credit agreement
(the "Credit Agreement") with a syndicate of senior lenders providing a senior
secured facility of $500 million. Among other things, the
 
                                      28

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
NOTE 4--LONG-TERM DEBT--(CONTINUED)
Credit Agreement: (1) is for a term of five years, expiring in January 2002;
(2) provides for interest rates ranging from LIBOR plus 25 basis points to
LIBOR plus 125 basis points based upon certain financial ratios (3) provides
for the release of security upon the attainment of certain financial ratios or
once the Company achieves investment grade senior, unsecured debt ratings from
two credit rating agencies; (4) provides for a borrowing base of 70% of the
eligible inventory; and (5) provides higher limits for possible acquisitions.
An extraordinary loss of $2.0 million (net of tax benefits of $1.3 million)
was recorded in fiscal 1997, representing the write-off of the unamortized
financing fees related to the retirement of the prior $380 million revolving
credit facility. In connection with the Credit Agreement, the Company incurred
approximately $3.0 million of financing fees which have been deferred and are
being amortized on a straight-line basis over the five-year term of the Credit
Agreement.
 
  Revolving loans made under the Credit Agreement may be prepaid during its
term without premium and may subsequently be reborrowed. Commitments under the
Credit Agreement may be permanently reduced in full or in part at any time at
the option of the Company upon prior written notice.
 
  Borrowings under the Credit Agreement bear interest at the rate of LIBOR
plus an applicable margin (.75% at September 30, 1998) or the applicable prime
rate. Interest on loans under the Credit Agreement is payable quarterly. Under
the terms of the Credit Agreement, the Company granted the senior lenders a
perfected first priority security interest in the Company's inventory for
collateral against borrowings under the Credit Agreement. The Company is
required to pay a commitment fee on the unused portion of commitments under
the Credit Agreement (.23% per annum at September 30, 1998) plus an annual
administration fee. At September 30, 1998, the $145.0 million outstanding
under the Credit Agreement bore interest at the rate of 6.9% per annum.
 
 Senior Debentures
 
  In fiscal 1996, the Company purchased and redeemed senior debentures that
were previously issued and outstanding. These transactions were funded by
proceeds from the Company's 1996 public offering and borrowings under the
Company's revolving credit agreement and resulted in an extraordinary charge
of $7.2 million (net of a $3.9 million tax benefit), related to the open
market purchase and tender offer premiums, transaction fees and the write-off
of related unamortized deferred financing fees.
 
  The Company enters into interest-rate cap agreements to hedge the exposure
to increasing interest rates with respect to its long-term debt. The Company
provides protection to meet actual interest rate exposures and does not
speculate in derivatives. The interest rate caps under these agreements exceed
the current market rates at the time they are entered into and their cost is
included in interest expense ratably over the life of the agreement. The
unamortized cost of the agreements ($83,000 at September 30, 1998) is included
in other assets. The Company is required by its Credit Agreement to maintain
interest rate protection on a minimum of $112.5 million of its long-term debt
through January 1999. The Company has entered into two-year interest rate cap
agreements expiring in May 1999 which specify that the 3-month LIBOR base rate
will not be greater than 7.50% with respect to $115 million of borrowings
under the Credit Agreement. The Company would incur additional interest
expense with respect to the borrowings if the LIBOR rate would exceed 7.50%
and the other parties to the interest rate cap agreements defaulted on their
obligations under the agreements. During fiscal 1998, the 3-month LIBOR rate
did not exceed 7.5%.
 
  The indentures governing the Receivables Program and the Credit Agreement
contain restrictions and covenants which include limitations on incurrence of
additional indebtedness, restrictions on distributions and dividends to
stockholders, the repurchase of stock and the making of certain other
restricted payments, the issuance of preferred stock, the creation of certain
liens, transactions with subsidiaries and other affiliates, and

certain corporate acts such as mergers, consolidations, and the sale of
substantially all assets. Additional covenants require compliance with
financial tests, including leverage, fixed charge coverage, and maintenance of
minimum net worth.
 
  Interest paid on the above indebtedness during the fiscal years ended
September 30, 1998, 1997, and 1996 was $44.4 million, $37.3 million, and $36.2
million, respectively.
 
  Total amortization of financing fees and expenses (included in interest
expense) for the fiscal years ended September 30, 1998, 1997, and 1996 was
$1.7 million, $1.9 million, and $2.4 million, respectively.
 
  As of September 30, 1998, the Company's revolving credit facility and
receivables securitization financing had fair values that approximated their
carrying amounts.
 
NOTE 5--STOCKHOLDERS' EQUITY
 
  In May 1996, the Company completed a public offering of 4,800,000 shares of
Class A common stock at a price of $35 per share. Of the 4,800,000 shares
sold, 1,500,000 were sold by the Company and 3,300,000 shares were sold by
certain stockholders of the Company (the "Selling Stockholders"). The Company
did not receive any of the proceeds from the shares sold by the Selling
Stockholders. The net proceeds of $49.3 million from the 1,500,000 shares sold
by the Company were used to repay long-term debt. On a pro forma basis,
assuming historical data is adjusted to reflect the public offering and
related pay-down of long-term debt as if they occurred on October 1, 1995,
earnings per share before extraordinary items for fiscal 1996 would not be
materially different from reported earnings per share.
 
  The holders of the Class A common stock are entitled to one vote per share
on all matters on which holders of Class A common stock are entitled to vote.
The holders of the Class A common stock may elect at any time to convert any
or all such shares into the Class B common stock on a share-for-share basis
(but only to the extent that such record holder of Class A common stock shall
be deemed to be required to convert such Class A common stock into Class B
common stock pursuant to applicable law).
 
  The rights of holders of Class B and Class C common stock and holders of
Class A common stock are substantially identical and entitle the holders
thereof to the same rights, privileges, benefits, and notices, except that
holders of Class B and Class C common stock generally do not possess the right
to vote on any matters to be voted upon by the stockholders of the Company,
except as provided by law. Holders of Class B and Class C common stock may
elect at any time to convert any and all of such shares into Class A common
stock, on a share-for-share basis, to the extent the holder thereof is not
prohibited from owning additional voting securities by virtue of regulatory
restrictions.
 
  The Class C common stock is subject to substantial restrictions on transfer
and has certain registration and "take-along" rights. A share of Class C
common stock will automatically be converted into a share of Class A common
stock (a) immediately prior to its sale in a future public offering or (b) at
such time as such share of Class C common stock has been sold publicly.
 
NOTE 6--PENSION AND OTHER BENEFIT PLANS
 
  The Company provides a benefit for the majority of its employees under
noncontributory defined benefit pension plans. For each employee, the benefits
are based on years of service and average compensation. Pension costs, which
are computed using the projected unit credit cost method, are funded on at
least the minimum amount required by government regulations.

a maximum of 6% of their regular compensation in an amount equal to 50% of the
participants' contributions. An additional discretionary Company contribution
in an amount not to exceed 50% of the participants' contributions may also be
made depending upon the Company's performance. All contributions are invested
at the direction of the employee in one or more funds. Employer contributions
vest over a five-year period depending upon an employee's years of service.
Costs of the plan charged to expense for the fiscal years ended September 30,
1998, 1997, and 1996 amounted to $1.9 million, $0.9 million, and $1.8 million,
respectively.
 
  As a result of special termination benefit packages previously offered, the
Company provides medical, dental, and life insurance benefits to only a
limited number of retirees and their dependents. These benefit plans are
unfunded. The accumulated postretirement benefit obligation was $0.7 million
as of September 30, 1998. The weighted average discount rate used in
determining the accumulated postretirement benefit obligations was 6.75% and
7.5% at September 30, 1998 and 1997, respectively. The annual expense for such
benefits is not material.
 
NOTE 7--STOCK OPTION PLANS
 
  Effective October 1, 1996, the Company adopted the disclosure-only option
under SFAS No. 123, "Accounting for Stock-Based Compensation." The Company
continues to use the accounting method under APB Opinion No. 25 ("APB 25") and
related interpretations for its employee stock options. Under APB 25,
generally when the exercise price of the Company's employee stock options
equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.
 
 
  During fiscal 1995, the Company adopted the AmeriSource Health Corporation
1995 Stock Option Plan (the "1995 Option Plan"), which provides for the
granting of nonqualified stock options to acquire up to approximately 1.2
million shares of common stock to employees of the Company at a price not less
than the fair market value of the common stock on the date the option is
granted. The option terms and vesting periods are determined at the date of
grant by a committee of the Board of Directors. Options expire six years after
the date of grant unless an earlier expiration date is set at the time of
grant.
 
  During fiscal 1995, the Company also adopted the AmeriSource Health
Corporation Non-Employee Director Stock Option Plan (the "1995 Directors
Plan"), which provides for the grant of stock options to the Company's non-
employee directors. Under the 1995 Directors Plan, stock options are granted
annually at the fair market value of the Company's common stock on the date of
grant. The number of options so granted annually is fixed by the plan. Such
options become fully exercisable on the first anniversary of their respective
grant, except for the options under the initial grant, which are fully
exercisable on the third anniversary of the grant. The total number of shares
to be issued under the 1995 Directors Plan may not exceed 50,000 shares.
 
  During fiscal 1997, the Company adopted the 1996 Employee Stock Option Plan
(the "1996 Option Plan") and the 1996 Non-Employee Directors Stock Option Plan
(the "1996 Directors Plan"). The 1996 Option Plan and the 1996 Directors Plan
provide for the granting of nonqualified stock options to acquire up to
797,000 and 50,000 shares of common stock, respectively, to employees and non-
employee directors at a price not less than the fair market value of the
common stock on the date the option is granted. The option terms and vesting
periods of the 1996 Option Plan are determined at the date of grant by a
committee of the Board of Directors. The number of options to be granted
annually under the 1996 Directors Plan is fixed by the plan and vest
immediately. Options expire ten years after the date of grant unless an
earlier expiration date is set at the time of grant.

</TABLE>
 
  Pro forma disclosures, as required by SFAS No. 123, regarding net income and
earnings per share have been determined as if the Company had accounted for
its employee stock options under the fair value method.
 
  Option valuation models use highly subjective assumptions to determine the
fair value of traded options with no vesting or trading restrictions. Because
options granted under the Company's Stock Option Plans have vesting
requirements and cannot be traded, and because changes in the assumptions can
materially affect the fair value estimate, in management's opinion, the
existing valuation models do not necessarily provide a reliable measure of the
fair value of its employee stock options.
 
  The fair values for the Company's options were estimated at the date of
grant using a Black-Scholes option pricing model with the following
assumptions for fiscal 1998: risk-free interest rate of 5.3%; no dividends; a
volatility factor of the expected market price of the Company's common stock
of .392 and a weighted-average expected life of the options of 5 years; for
fiscal 1997 and fiscal 1996: risk-free interest rate of 6.0%; no dividends; a
volatility factor of the expected market price of the Company's common stock
of .321 and a weighted-average expected life of the options of 5 years.

NOTE 7--STOCK OPTION PLANS--(CONTINUED)
 
  For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' assumed vesting period. SFAS
No. 123 requires only that the income effects of options granted during fiscal
1998, fiscal 1997 and fiscal 1996 be included in the pro forma disclosures.
Since a portion of the Company's stock options vest over several years and
additional options may be granted each year, the pro forma effect on net
income reported below is not representative of the effect of fair value stock
option expense on future years' pro forma net income. The Company's pro forma
information follows (in thousands, except per share data):

NOTE 8--LEASES
 
  At September 30, 1998, future minimum payments totaling $51.6 million under
noncancelable operating leases with remaining terms of more than one fiscal
year were due as follows: 1999--$13.1 million; 2000--$9.5 million; 2001--$7.0
million; 2002--$5.1 million; 2003--$3.7 million; and thereafter (through
2010)--$13.2 million. In the normal course of business, operating leases are
generally renewed or replaced by other leases.
 
  Total rental expense was $16.0 million in fiscal 1998, $14.0 million in
fiscal 1997, and $9.7 million in fiscal 1996.
 
NOTE 9--FACILITY CONSOLIDATIONS AND EMPLOYEE SEVERANCE
 
  In the fourth quarter of fiscal 1998 the Company began to centralize its
data processing, accounting and contract administration functions, reorganize
its pharmaceutical distribution facilities into six regions, and consolidate a
pharmaceutical distribution facility into another facility. The centralization
process, which commenced in July 1998, is occurring on a facility-by-facility
basis and is expected to be complete by the end of 1999.
 
  In the third quarter of fiscal 1997 the Company commenced cost reduction
plans to consolidate three of its pharmaceutical distribution facilities into
other existing facilities and restructure its sales force. These initiatives
were completed in fiscal 1998. In addition the Company incurred costs related
to the retirement of its former President and CEO as well as other executive
terminations during fiscal 1997.
 
  The cost reduction initiatives referred to above resulted in the following
charges for the fiscal year ended September 30 (in thousands):

NOTE 9--FACILITY CONSOLIDATIONS AND EMPLOYEE SEVERANCE--(CONTINUED)
  Write-downs of assets in 1998 relate primarily to computer equipment to be
abandoned as a result of the data processing centralization. In fiscal 1997,
write-downs of assets related to buildings, warehouse and computer equipment
and other assets to be disposed of primarily due to the facility
consolidations. The write-downs of assets were based on estimated salvage and
market values of related facilities and equipment compared to carrying values.
Computer and warehouse equipment were determined to have minimal salvage value
based on Company estimates.
 
  Severance includes the termination of approximately 350 administrative and
warehouse employees in fiscal 1998 and 240 warehouse and sales employees in
fiscal 1997. All of the employees targeted in fiscal 1997 and 25 of the
employees targeted in fiscal 1998 were terminated by September 30, 1998.
Accrued severance of $4.3 million, including executive severance of $1.4
million, at September 30, 1998 is included in accrued expenses and other.
 
  Lease cancellations and other in fiscal 1998 relates primarily to non-
cancellable lease obligations remaining after the conversion dates for
computer equipment to be abandoned as a result of the data processing
centralization. In fiscal 1997, lease cancellations and other relates
primarily to non-cancellable lease obligations of the consolidated facilities.
Remaining lease obligations of $3.0 million are included in accrued expenses
and other at September 30, 1998.
 
NOTE 10--LEGAL MATTERS AND CONTINGENCIES
 
  In the ordinary course of its business, the Company becomes involved in
lawsuits, administrative proceedings, and governmental investigations,
including antitrust, environmental, product liability, and regulatory agency
and other matters. In some of these proceedings, plaintiffs may seek to
recover large and sometimes unspecified amounts and the matters may remain
unresolved for several years. On the basis of information furnished by counsel
and others, the Company does not believe that these matters, individually or
in the aggregate, will have a material adverse effect on its business or
financial condition.
 
  A former customer of the Company has alleged that the Company failed to
fulfill its obligations under the service contract between the Company and the
former customer. In connection with this claim, the former customer withheld
payment on $22 million of invoices. In response, the Company filed suit to
collect the outstanding amount. The former customer has countersued the
Company for an unspecified amount. The Company believes there is no merit to
this counterclaim and intends to aggressively pursue collection of the
outstanding amount. Because the Company is unable at this time to determine
the outcome of this matter, no provision for loss has been made.
 
  In November 1993, the Company was named a defendant, along with six other
wholesale distributors and twenty-four pharmaceutical manufacturers, in a
series of purported class action antitrust lawsuits brought by retail
pharmacies and alleging violations of various antitrust laws stemming from the
use of chargeback agreements. In addition, the Company and four other
wholesale distributors were added as defendants in a series of related
antitrust lawsuits brought by independent pharmacies and chain drug stores,
both of which opted out of the class cases. The Company also was named a
defendant in parallel suits filed in state courts in Minnesota, Alabama,
Tennessee and Mississippi. The federal class actions were originally filed in
the United States District Court for the Southern District of New York, but
were transferred along with the individual and chain drug store cases to the
United States District Court for the Northern District of Illinois. Plaintiffs
seek injunctive relief, treble damages, attorneys' fees and costs. In October
1994, the Company entered into a Judgment Sharing Agreement with the other
wholesaler and pharmaceutical manufacturer defendants. Under the Judgment
Sharing Agreement: (a) the manufacturer defendants agreed to reimburse the
wholesaler defendants for litigation costs

NOTE 10--LEGAL MATTERS AND CONTINGENCIES--(CONTINUED)
incurred up to an aggregate of $9 million; and (b) if a judgment is entered
against both manufacturers and wholesalers, the total exposure for joint and
several liability of the Company is limited to the lesser of 1% of such
judgment or $1 million. In addition, the Company has released any claims which
it might have had against the manufacturers for the claims presented by the
Plaintiffs in these lawsuits. The Judgment Sharing Agreement covers the
federal court litigation as well as the cases which have been filed in various
state courts.
 
  On April 4, 1996, the District Court granted the Company's motion for
summary judgment in the class case. Plaintiffs subsequently appealed the
Company's grant of summary judgment to the United States Court of Appeals for
the Seventh Circuit. On August 15, 1997, the Court of Appeals reversed the
District Court's order granting summary judgment in favor of the Company and
the other wholesalers. The Court of Appeals also denied the Company's petition
for rehearing. The Company and the other wholesalers filed a petition for a
writ of certiorari to the United States Supreme Court; the petition was
denied. Trial in the class case commenced in the United States District Court
for the Northern District of Illinois on September 23, 1998. After a ten-week
trial, the Court granted all of the defendants motions for a directed verdict
and dismissed the claims the class plaintiffs had asserted against the Company
and the other defendants.
 
  On or about October 2, 1997, a group of retail chain drug stores and
individual pharmacies, both of which had opted-out of the class cases, filed a
motion with the United States District Court for the Northern District of
Illinois seeking to add the Company and the other wholesale distributors as
defendants in their cases against the manufacturer defendants, which cases are
consolidated before the same judge who is presently presiding over the class
case. This motion was granted and the Company and the other wholesale
distributors have been added as defendants in those cases as well. As a
result, the Company has been served with approximately 120 additional
complaints on behalf of approximately 4,000 pharmacies and chain retailers.
Discovery and motion practice is presently underway in all of these opt-out
cases. The Company believes it has meritorious defenses to the claims asserted
in these lawsuits and intends to vigorously defend itself in all of these
cases.
 
  The Company is subject to contingencies pursuant to environmental laws and
regulations at one of its former distribution centers that may require the
Company to take remediation efforts. In fiscal 1994, the Company accrued $4.1
million to cover future consulting, legal, and remediation and ongoing
monitoring costs. The accrued liability, which is reflected in other long-term
liabilities on the accompanying consolidated balance sheet ($3.8 million at
September 30, 1998), is based on an engineering analysis prepared by outside
consultants and represents an estimate of the extent of contamination and
choice of remedy based on existing technology and presently enacted laws and
regulations. However, changes in remediation standards, improvements in
cleanup technology and discovery of additional information concerning the site
could affect the estimated liability in the future. The Company is
investigating the possibility of asserting claims against responsible parties
for recovery of these costs. Whether or not any recovery may be forthcoming is
unknown at this time, although the Company intends to vigorously enforce its
rights and remedies.
 
NOTE 11--MERGER COSTS--TERMINATED MERGER AGREEMENT
 
  On September 22, 1997 the Company and McKesson Corporation signed a
definitive merger agreement which was subsequently approved by both companies'
shareholders on February 9, 1998. On March 9, 1998, the Federal Trade
Commission (FTC) filed a complaint in the United States District Court for the
District of Columbia seeking a preliminary injunction to halt the proposed
merger. On July 31, 1998, the District Court granted the FTC's request for an
injunction to halt the proposed merger. On August 7, 1998, the Company and
McKesson jointly terminated the merger agreement. Merger related costs
consisting of professional fees and stay-put bonuses totaling $18.4 million
were expensed in the fourth quarter of fiscal 1998 as a result of the
termination of the merger agreement.

           SCHEDULE-I CONDENSED FINANCIAL INFORMATION OF REGISTRANT
 
                    NOTES TO CONDENSED FINANCIAL STATEMENTS
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The accompanying condensed financial statements present the financial
position, results of operations and cash flows of AmeriSource Health
Corporation (the "Company") as of the dates and for the periods indicated in
accordance with Rule 12-04 of Regulation S-X of the Securities Exchange Act of
the Securities and Exchange Commission and, accordingly, do not include the
accounts of its wholly-owned subsidiaries. The Company's primary asset is its
investment in and receivables from AmeriSource Corporation, which is a wholly-
owned subsidiary of the Company. Substantially all of the Company's operations
are transacted by AmeriSource Corporation. The ability of the Company to pay
its obligations depends on the operations of AmeriSource Corporation.
 
  These condensed financial statements should be read in conjunction with the
Consolidated Financial Statements of AmeriSource Health Corporation and
Subsidiaries contained in Item 8 of this document for more information on
long-term debt, stockholders' equity and other disclosures.
 
NOTE 2--LONG-TERM DEBT
 
  In fiscal 1996, the Company purchased and redeemed senior debentures that
were previously issued and outstanding. These transactions were funded by
proceeds from the Company's 1996 public offering and borrowings under the
Company's revolving credit agreement and resulted in an extraordinary charge
in fiscal 1996 of $7.2 million (net of a $3.9 million tax benefit) related to
the open market purchase and tender offer premiums, transaction fees and the
write-off of related unamortized deferred financing fees.
 
NOTE 3--STOCKHOLDERS' EQUITY
 
  In May 1996, the Company completed a public offering of 4,800,000 shares of
Class A common stock at a price of $35 per share. Of the 4,800,000 shares
sold, 1,500,000 were sold by the Company and 3,300,000 were sold by certain
stockholders of the Company (the "Selling Stockholders"). The Company did not
receive any of the proceeds from the shares sold by the selling stockholders.
The net proceeds of $49.3 million from the 1,500,000 shares sold by the
Company were invested in AmeriSource Corporation to reduce its indebtedness.
AmeriSource Corporation borrowings from its revolving credit facility were
used to retire and redeem the Senior Debentures as described in Note 2.

      notice shall be deemed to be a request for an Interest Period of one
      month, or (II) the type of Revolving Loan requested, then such notice
      shall be deemed to be a request for a Base Rate Loan hereunder. The
      Administrative Agent shall give notice to each Lender promptly upon
      receipt of each Notice of Borrowing pursuant to this Section 2.1 (b)(i),
      the contents thereof and each such Lender's share of any borrowing to be
      made pursuant thereto.

          (ii)   Minimum Amounts.  Each Revolving Loan shall be in a minimum
                 ---------------

     Percentage of each Revolving Loan borrowing available to the Administrative
     Agent for the account of the Borrower as specified in Section 3.14(a), or 
     in such other manner as the Administrative

                                       8

     Agent may specify in writing by 2.00 P.M. (Charlotte, North Carolina time)
     on the date specified in the applicable Notice of Borrowing in Dollars and
     in funds immediately available to the Administrative Agent. Such borrowing
     will then be made available to the Borrower by the Administrative Agent by
     crediting the account of the Borrower on the books of such office with the
     aggregate of the amounts made available to the Administrative Agent by the
     Lenders and in like funds as received by the Administrative Agent.

     (c)  Repayment.  The principal amount of all Revolving Loans shall be due
          ---------

          (i)   Base Rate Loans. During such periods as Revolving Loans shall be
                ---------------                                                
     comprised in whole or in part of Base Rate Loans, such Base Rate Loans
     shall bear interest at a per annum rate equal to the Base Rate plus
                                                                    ----
     one and one-fourth percent (1/4/%); and

          (ii)  Eurodollar Loans. During such periods as Revolving Loans shall 
                ----------------
     be comprised in whole or in part of Eurodollar Loans, such Eurodollar Loans
     shall bear interest at a per annum rate equal to the applicable Eurodollar
     Rate plus one and one-fourth percent (1-1/4%).
          ----                                     

     Interest on Revolving Loans shall be payable in arrears on each applicable
     Interest Payment Date (or at such other times as may be specified herein).

     (e)  Revolving Notes. The Revolving Loans shall be evidenced by a duly
          ---------------

maximum number of six (6) Eurodollar Loans outstanding at any time. For purposes
hereof, Eurodollar Loans with separate or different Interest Periods will be
considered as separate Eurodollar Loans even if their Interest Periods expire on
the same date.

                OTHER PROVISIONS RELATING TO CREDIT FACILITIES
                ----------------------------------------------

     3.1  DEFAULT RATE.
          ------------

          Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable upon written demand by the Administrative Agent, at
a per annum rate 2% greater than the rate which would otherwise be applicable
(or if no rate is applicable, whether in respect of interest, fees or other
amounts, then 2% greater than the Base Rate).

     3.2  EXTENSION AND CONVERSION.
          ------------------------ 

                                       9
<PAGE>
 
          Subject to the terms of Section 5.3, the Borrower shall have the
option, on any Business Day, to extend existing Loans into a subsequent
permissible Interest Period or to convert Loans into Loans of another interest
rate type; provided, however, that (i) except as provided in Section 3.8,
           --------  -------                                             
Eurodollar Loans may be converted into Base Rate Loans only on the last day of
the Interest Period applicable thereto, (ii) Eurodollar Loans may be extended, 
and Base Rate Loans may be converted into Eurodollar Loans, only if no Default
or Event of Default is in existence on the date of extension or conversion, 
(iii) Loans extended as, or converted into, Eurodollar Loans shall be subject 
to the terms of the definition of "Interest Period" set forth in Section 1.1 
                                   ---------------
and shall be in such minimum amounts as provided in Section 2.1(b)(ii), and 
(iv) any  request for extension or conversion of a Eurodollar Loan which shall 
fail to specify an Interest Period shall be deemed to be a request for an 
Interest Period of one month. Each such extension or conversion shall be 
effected by the Borrower by giving a Notice of Extension/Conversion 
substantially in the form of Schedule 3.2 (or telephone notice promptly 
                             ------------
confirmed in writing) to the Administrative Agent prior to 12:00 Noon

conversion of a Eurodollar Loan into a Base Rate Loan, and on the third Business
Day prior to, in the case of the extension of a Eurodollar Loan as, or
conversion of a Base Rate Loan into, a Eurodollar Loan, the date of the proposed
extension or conversion, specifying the date of the proposed extension or
conversion, the Loans to be so extended or converted, the types of Loans into
which such Loans are to be converted and, if appropriate, the applicable
Interest Periods with respect thereto. Each request for extension or conversion
shall be irrevocable and shall constitute a representation and warranty by the
Borrower of the matters specified in subsections (a) through (e) of Section 5.3.
In the event the Borrower fails to request extension or conversion of any
Eurodollar Loan in accordance with this Section, or any such conversion or
extension is not permitted or required by this Section, then such Eurodollar
Loan shall be automatically converted into a Base Rate Loan at the end of the
Interest Period applicable thereto. The Administrative Agent shall give each
Lender notice as promptly as practicable of any such proposed extension or
conversion affecting any Loan.

     3.3  VOLUNTARY PREPAYMENTS.
          ---------------------

     Revolving Loans may be repaid in whole or in part without premium or
penalty; provided that (i) Eurodollar Loans may be prepaid only upon three (3)

Business Days' prior written notice to the Administrative Agent and must be
accompanied by payment of any amounts owing under Section 3.11, and (ii)
partial repayments shall be in minimum principal amounts of $1,000,000, in the
case of Eurodollar Loans, and $500,000, in the case of Base Rate Loans.

     3.4  REDUCTIONS IN COMMITMENTS AND MANDATORY PREPAYMENTS.
          ---------------------------------------------------

          (a)  Voluntary Reduction in Revolving Commitment.  The Revolving
               ---------------------------------------------                
Commitments may be terminated or permanently reduced in whole or in part upon
three (3) Business Days' prior written notice to the Administrative Agent,
provided that (i) after giving effect to any voluntary reduction the aggregate
- - --------                                                                       
amount of Obligations shall not exceed the lesser of (A) the Aggregate
Revolving Committed Amount, as reduced, or (B) until the Security Release
Date relating to inventory (but not thereafter), the Borrowing Base, and (ii)
partial reductions shall be in minimum principal amounts of $5,000,000, and in
integral multiples of $1,000,000 in excess thereof.

          (b)  Mandatory Reductions in Revolving Commitments and Mandatory
               ------------------------------------------------------------
Prepayments.  The Revolving Commitments shall be automatically and permanently
- - -----------                                                                   
reduced (and

                                      10
<PAGE>
 
prepayments shall be required to the extent that outstanding Obligations exceed
the respective Revolving Commitment, as so reduced), by the amounts provided
below;

               (i)    Asset Dispositions.  An amount equal to one hundred
                      ------------------
     percent (100%) of the Net Proceeds received from Asset Dispositions.

               (ii)   Debt and Equity Transactions.  An amount equal to one
                      ----------------------------
     hundred percent (100%) of the Net Proceeds received from any Debt

          (c)  Mandatory Prepayments, Etc.
               -------------------------- 

               (i)    If at any time the aggregate principal amount of
     Obligations hereunder shall exceed the lesser of (A) the Aggregate
     Revolving Committed Amount or (B) until the Security Release Date relating
     to inventory (but not thereafter), the Borrowing Base, the Borrower shall
     immediately make payment on the Revolving Loans hereunder in an amount
     sufficient to eliminate the deficiency.

               (ii)   If at any time the Aggregate Revolving Committed Amount
     under the Existing Credit Agreement shall exceed the Obligations owing
     thereunder (that is, there is unused availability under the Existing Credit
     Agreement determined for purposes hereof without giving effect to any
     voluntary, optional or mandatory reduction in the Aggregate Revolving
     Committed Amount thereunder in effect on the Closing Date hereof, being
     $500,000,000), the Borrower shall immediately either (A) make payment on
     the Revolving Loans hereunder in an amount sufficient to reduce the
     Obligations outstanding hereunder to zero or (B) reborrow Revolving Loans
     (or have Letters of Credit issued) under the Existing Credit Agreement in
     an amount sufficient to eliminate such excess.

               (iii)  The Borrower will make prepayment on the Revolving Loans
     hereunder in an amount equal to one hundred percent (100%) of the Net
     Proceeds received from any Securitization Transaction (including for
     purposes hereof any increase in aggregate Invested Amount relating to the
     Excluded Securitization Transaction above $285,000,000).

          (d)  Application.  Unless otherwise specified by the Borrower,
               -----------                                              
prepayments made hereunder shall be applied first to Base Rate Loans, then to
Eurodollar Loans in direct order of Interest Period maturities. Amounts prepaid
hereunder may be reborrowed in accordance with the provisions hereof.

          (e)  Mandatory Commitment Termination.  The Commitments hereunder
               --------------------------------
shall terminate on the Termination Date.

     3.5  FEES.
          ----

          (a)  Commitment Fee.  In consideration of the Revolving Commitments
               --------------
hereunder, the Borrower agrees to pay to the Administrative Agent for the
ratable benefit of the Lenders a commitment fee (the "Commitment Fee") equal to
                                                      --------------           
31.25 basis points (.3125%) per

                                       11
<PAGE>
 
annum on the average daily unused amount of the Revolving Committed Amount for
the applicable period from the Closing Date.  The Commitment Fee shall be
payable quarterly in arrears on the 15th day following the last day of each
calendar quarter for the immediately preceding quarter (or portion thereof)
beginning with the first such date to occur after the Closing Date.

          (b)  Administrative Fees. The Borrower agrees to pay to the 
               -------------------
Administrative Agent, for its own account, an annual administrative fee and
such other fees, if any, referred to in the Administrative Agent's Fee Letter
(collectively, the "Administrative Agent's Fees").
                    ---------------------------        

     3.6  CAPITAL ADEQUACY.
          ---------------- 

          If any Lender has determined, after the date hereof, that the adoption
or the becoming effective of, or any change in, or any change by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate
of return on such Lender's capital or assets as a consequence of its commitments
or obligations hereunder to a level below that which such Lender could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy), then,
upon notice from such Lender to the Borrower, the Borrower shall be obligated to
pay to such Lender such additional amount or amounts as will compensate such
Lender on an after-tax basis for such reduction. Each determination by any such
Lender of amounts owing under this Section shall, absent manifest error, be
conclusive and binding on the parties hereto.

     3.7  INABILITY TO DETERMINE INTEREST RATE.
          ------------------------------------  

     If prior to the first day of any Interest Period, the Administrative
Agent shall have determined (which determination shall be conclusive and binding
upon the Borrower absent manifest error) that, by reason of circumstances
affecting the relevant market, adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Interest Period, the Administrative
Agent shall give telecopy or telephonic notice thereof to the Borrower and the
Lenders as soon as practicable thereafter. If such notice is given (a) any
Eurodollar Loans requested to be made on the first day of such Interest Period
shall be made as Base Rate Loans and (b) any Loans that were to have been
converted on the first day of such Interest Period to or continued as Eurodollar
Loans shall be converted to or continued as Base Rate Loans. Until such notice
has been withdrawn by the Administrative Agent, no further Eurodollar Loans
shall be made or continued as such, nor shall the Borrower have the right to
convert Base Rate Loans to Eurodollar Loans.

     3.8  ILLEGALITY.
          ---------- 

     Notwithstanding any other provision herein, if the adoption of or any 
change in any Requirement of Law or in the interpretation or application thereof
occurring after the Closing Date shall make it unlawful for any Lender to make
or maintain Eurodollar Loans as contemplated by this Credit Agreement, (a) such
Lender shall promptly give written notice of such circumstances to the Borrower
and the Administrative Agent (which notice shall be withdrawn whenever such
circumstances no longer exist), (b) the commitment of such Lender hereunder to
make Eurodollar

                                      12
<PAGE>
 
Loans, continue Eurodollar Loans as such and convert a Base Rate Loan to
Eurodollar Loans shall forthwith be canceled and, until such time as it shall no
longer be unlawful for such Lender to make or maintain Eurodollar Loans, such
Lender shall then have a commitment only to make a Base Rate Loan when a
Eurodollar Loan is requested and (c) such Lender's Loans then outstanding as
Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on
the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law. If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrower shall pay to
such Lender such amounts, if any, as may be required pursuant to Section 3.11.

     3.9  REQUIREMENTS OF LAW.
          ------------------- 

     If, after the date hereof, the adoption of or any change in any Requirement
of Law or in the interpretation or application thereof applicable to any Lender,
or compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority, in each
case made subsequent to the Closing Date (or, if later, the date on which such
Lender becomes a Lender):

              (a) shall subject such Lender to any tax of any kind whatsoever
     with respect to any Eurodollar Loans made by it or its obligation to make
     Eurodollar Loans, or change the basis of taxation of payments to such
     Lender in respect thereof (except for (i) Non-Excluded Taxes covered by
     Section 3.10 (including Non-Excluded Taxes imposed solely by reason of any
     failure of such Lender to comply with its obligations under Section
     3.10(b)) and (ii) changes in taxes measured by or imposed upon the overall
     net income, or franchise tax (imposed in lieu of such net income tax), of
     such Lender or its applicable lending office, branch, or any affiliate
     thereof));

              (b) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

              (c) shall impose on such Lender any other condition (excluding any
     tax of any kind whatsoever);
     
and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, upon notice to the
Borrower from such Lender, through the Administrative Agent, in accordance
herewith, the Borrower shall be obligated to promptly pay such Lender, upon its
demand, any additional amounts necessary to compensate such Lender on an after-
tax basis for such increased cost or reduced amount receivable, provided that,
                                                                --------      
in any such case the Borrower may elect to convert the Eurodollar Loans made by
such Lender hereunder to Base Rate Loans by giving the Administrative Agent at
least one Business Day's notice of such election, in which case the Borrower
shall promptly pay to such Lender, upon demand, without duplication, such
amounts, if any, as may be required pursuant to Section 3.11. If any Lender
becomes entitled to claim any additional amounts pursuant to this subsection, it
shall provide prompt notice thereof to the Borrower, through the Administrative
Agent,

                                      13
<PAGE>
 
certifying (x) that one of the events described in this paragraph 3.9 has
occurred and describing in reasonable detail the nature of such event, (y) as to
the increased cost or reduced amount resulting from such event and (z) as to the
additional amount demanded by such Lender and a reasonably detailed explanation
of the calculation thereof. Such a certificate as to any additional amounts
payable pursuant to this subsection submitted by such Lender, through the
Administrative Agent, to the Borrower shall be conclusive and binding on the
parties hereto in the absence of manifest error. This covenant shall survive the
termination of this Credit Agreement and the payment of the Loans and all other
amounts payable hereunder.

     3.10 TAXES.
          -----

     (a)  Except as provided below in this subsection, all payments made by the
Borrower or any Guarantor under this Credit Agreement and any Notes shall be
made free and clear of, and without deduction or withholding for or on account
of, any present or future income, stamp or other taxes, levies, imposts, duties,
charges, fees, deductions or withholdings, now or hereafter imposed, levied,
collected, withheld or assessed by any court, or governmental body, agency or
other official, excluding taxes measured by or imposed upon the overall net
income of any Lender or its applicable lending office, or any branch or
affiliate thereof, and all franchise taxes, branch taxes, taxes on doing
business or taxes on the overall capital or net worth of any Lender or its
applicable lending office, or any branch or affiliate thereof, in each case
imposed in lieu of net income taxes, imposed: (i) by the jurisdiction under the
laws of which such Lender, applicable lending office, branch or affiliate is
organized or is located, or in which its principal executive office is located,
or any nation within which such jurisdiction is located or any political
subdivision thereof; or (ii) by reason of any connection between the
jurisdiction imposing such tax and such Lender, applicable lending office,
branch or affiliate other than a connection arising solely from such Lender
having executed, delivered or performed its obligations, or received payment
under or enforced, this Credit Agreement or any Notes. If any such non-excluded
taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-
                                                                            ----
Excluded Taxes") are required to be withheld from any amounts payable to the
- - --------------
Administrative Agent or any Lender hereunder or under any Notes, (A) the amounts
so payable to the Administrative Agent or such Lender shall be increased to the
extent necessary to yield to the Administrative Agent or such Lender (after
payment of all Non-Excluded Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Credit Agreement and
any Notes, provided, however, that the Borrower shall be entitled to deduct and
           --------  -------
withhold any Non-Excluded Taxes and shall not be required to increase any such
amounts payable to any Lender that is not organized under the laws of the United
States of America or a state thereof if such Lender fails to comply with the
requirements of paragraph (b) of this subsection whenever any Non-Excluded Taxes
are payable by the Borrower, and (B) as promptly as possible thereafter the
Borrower shall send to the Administrative Agent for its own account or for the
account of such Lender, as the case may be, a certified copy of an original
official receipt received by the Borrower showing payment thereof or other
evidence of remittance of Non-Excluded Taxes reasonably acceptable to the
Administrative Agent. If the Borrower fails to pay any Non-Excluded Taxes when
due to the appropriate taxing authority or fails to remit to the Administrative
Agent the required receipts or other required documentary evidence, the Borrower
shall indemnify the Administrative Agent and the Lenders for any incremental
taxes, interest or penalties that may become payable by the Administrative Agent
or any Lender as a result of any such failure. The agreements in this subsection
shall survive the termination of this Credit Agreement and the payment of the
Loans and all other amounts payable hereunder.

     (b)  Each Lender that is not incorporated or organized under the laws of
the United States of America or a state thereof shall:

     Borrower and the Administrative Agent (A) two (2) properly completed and

     further properly completed and duly executed copies of any such form or
     certification on or before the date that any such form or certification
     expires or becomes obsolete and after the occurrence of any event requiring
     a change in the most recent form previously delivered by it to the 
     Borrower; and

          (iii)  obtain such extensions of time for filing and complete such
     forms or certifications as may reasonably be requested by the Borrower or
     the Administrative Agent; or

          (Y)    in the case of any such Lender that is not a "bank" within the
     meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (i) on or
     before the date it becomes a Lender, deliver to the Borrower (for the
     benefit of the Borrower and the Administrative Agent) (A) a statement under

     Form W-8, or successor applicable form certifying to such Lender's legal
     entitlement at the date of such certificate to an exemption from U.S.
     withholding tax under the provisions of Section 881(c) of the Internal
     Revenue Code with respect to payments to be made under this Credit
     Agreement and any Notes (ii) deliver to the Borrower and the Administrative
     Agent two (2) further properly completed and duly executed copies of such
     form on or before the date it expires or becomes obsolete and after the
     occurrence of any event requiring a change in the most recently provided
     form, (iii) if necessary, obtain any extensions of time reasonably
     requested by the Borrower or the Administrative Agent for filing and
     completing such forms, and (iv) agree, to the extent legally entitled to do
     so, upon reasonable request by the Borrower, to provide to the Borrower
     (for the benefit of the Borrower and the Administrative Agent) such other
     forms as may be reasonably required in order to establish the legal
     entitlement of such Lender to an exemption from withholding with respect to
     payments under this Credit Agreement and any Notes;

unless in any such case any change in treaty, law or regulation has occurred
after the date such Person becomes a Lender hereunder which renders all such
forms inapplicable or which would prevent such Lender from duly completing and
delivering any such form with respect to it and such Lender so advises the
Borrower and the Administrative Agent.  Each Person that shall become a Lender
or a participant of a Lender pursuant to subsection 9.3 shall and each Lender
shall, upon a change in its applicable lending office, upon the effectiveness of
the related transfer, be required to provide all of

                                      15

the forms, certifications and statements required pursuant to this subsection,
provided that in the case of a participant of a Lender the obligations of such
- - --------                                                                      
participant of a Lender pursuant to this subsection (b) shall be determined as
if the participant of a Lender were a Lender except that such participant of a
Lender shall furnish all such required forms, certifications and statements to
the Lender from which the related participation shall have been purchased.

     (c)   If any Lender shall become aware that it is entitled to claim a
refund or credit (such credit to include any increase in any foreign tax credit)
in respect of any Non-Excluded Taxes (including any penalties or interest with
respect thereto) as to which it has been indemnified by the Borrower or with
respect to which the Borrower has paid increased amounts pursuant to this
Section 3.10, it shall promptly notify the Borrower of the availability of such
refund or credit and shall, within 30 days after receipt of a request by the
Borrower, apply for such refund or credit. If any Lender receives a refund or
credit (such credit to include any increase in any foreign tax credit) in
respect of any Non-Excluded Taxes as to which it has been indemnified by The
Borrower or with respect to which the Borrower has paid increased amounts under
this Section 3.10, it shall promptly notify the Borrower of such refund or
credit and shall, within 30 days after receipt of such refund or the benefit of
such credit (such benefit to include any reduction of the taxes for which the
Lender would otherwise be liable due to any increase in any foreign tax credit
available to such Lender) repay the amount of such refund or benefit of such
credit to the Borrower (to the extent of amounts that have been paid by the
Borrower under this Section 3.10 with respect to Non-Excluded Taxes giving rise
to such refund or credit), plus any interest received with respect thereto, net
or all reasonable out-of-pocket expenses of such Lender and without interest
(other than interest actually received from the relevant taxing authority or
other governmental authority with respect to such refund or credit); provided,
                                                                     --------
however, that the Borrower, upon the request of such Lender, agrees to return

the amount of such refund or benefit of such credit (plus interest) to such
Lender in the event such Lender is required to repay the amount of such refund
or benefit of such credit to the relevant taxing authority or other
governmental authority.

     (d)   Each Lender represents that it is not participating in, and will not
participate in, a conduit financing arrangement within the meaning of Treas.
Reg. (S) 1.881-3(a)(2)(iv) in connection with the Loans.

     3.11  Indemnity.
           --------- 

     The Borrower promises to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur (other
than through such Lender's gross negligence or willful misconduct) as a
consequence of (a) default by the Borrower in making a borrowing of, conversion
into or continuation of Eurodollar Loans after the Borrower has given a notice
requesting the same in accordance with the provisions of this Credit Agreement,
(b) default by the Borrower in making any prepayment of a Eurodollar Loan after
the Borrower has given a notice thereof in accordance with the provisions of
this Credit Agreement or (c) the making of a prepayment of Eurodollar Loans on a
day which is not the last day of an Interest Period with respect thereto. With
respect to Eurodollar Loans, such indemnification may include an amount equal to
the excess, if any, of (i) the amount of interest which would have accrued on
the amount so prepaid, or not so borrowed, converted or continued, for the
period from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of the applicable Interest Period (or, in the case of a
failure to borrow, convert or continue, the Interest Period that would have
commenced on the date of such failure) in each case at the applicable rate of
interest for such Eurodollar Loans provided for

                                      16
<PAGE>
 
herein (excluding, however, the Applicable Percentage included therein, if any)
over (ii) the amount of interest (as reasonably determined by such Lender) which
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank Eurodollar
market. The covenants of the Borrower set forth in this Section 3.11 shall
survive the termination of this Credit Agreement and the payment of the Loans
and all other amounts payable hereunder.

     3.12   PRO RATA TREATMENT.
            ------------------ 

     Except to the extent otherwise provided herein:

     (a)    Loans. Each Loan, each payment or prepayment of principal of any
            -----
Loan, each payment of interest on the Loans, each payment of Commitment Fees,
each reduction of the Revolving Committed Amount and each conversion or
extension of any Loan, shall be allocated pro rata among the Lenders in
accordance with the respective principal amounts of their outstanding Loans and
Participation Interests.

     (b)    Advances. Unless the Administrative Agent shall have been notified
            --------
in writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its ratable share of such borrowing available to
the Administrative Agent, the Administrative Agent may assume that such Lender
is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such amount is not made available to the
Administrative Agent by such Lender within the time period specified therefor
hereunder, such Lender shall pay to the Administrative Agent, on demand, such
amount with interest thereon at a rate equal to the Federal Funds Rate for the
period until such Lender makes such amount immediately available to the 
Administrative Agent. A certificate of the Administrative Agent submitted to any
Lender with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error.

     3.13   SHARING OF PAYMENTS.
            ------------------- 

     The Lenders agree among themselves that, in the event that any Lender shall
obtain payment in respect of any Loan or any other obligation owing to such
Lender under this Credit Agreement through the exercise of a right of setoff,
banker's lien or counterclaim, or pursuant to a secured claim under Section 506
of Title 11 of the United States Code or other security or interest arising from
or in lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other means,
in excess of its pro rata share of such payment as provided for in this Credit
Agreement, such Lender shall promptly purchase from the other Lenders a
participation in such Loans, and other obligations in such amounts, and make
such other adjustments from time to time, as shall be equitable to the end that
all Lenders share such payment in accordance with their respective ratable
shares as provided for in this Credit Agreement. The Lenders further agree among
themselves that if payment to a Lender obtained by such Lender through the
exercise of a right of setoff, banker's lien, counterclaim or other event as
aforesaid shall be rescinded or must otherwise be restored, each Lender which
shall have shared the benefit of such payment shall, by repurchase of a
participation theretofore sold, return its share of that benefit (together with
its share of any accrued interest payable with respect thereto) to each Lender
whose payment shall have been rescinded or otherwise restored. The Borrower
agrees that any Lender so purchasing such a participation may, to the fullest
extent permitted by law, exercise all rights of payment, including

                                       17
<PAGE>
 
setoff, banker's lien or counterclaim, with respect to such participation as
fully as if such Lender were a holder of such Loan, or other obligation in the
amount of such participation. Except as otherwise expressly provided in this
Credit Agreement, if any Lender or the Administrative Agent shall fail to remit
to the Administrative Agent or any other Lender an amount payable by such Lender
or the Administrative Agent to the Administrative Agent or such other Lender
pursuant to this Credit Agreement on the date when such amount is due, such
payments shall be made by the Administrative Agent or such Lender, as the case
may be, together with interest thereon for each date from the date such amount
is due until the date such amount is paid to the Administrative Agent or such
other Lender at a rate per annum equal to the Federal Funds Rate. If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section 3.13 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders under this
Section 3.13 to share in the benefits of any recovery on such secured claim.

     3.14   PAYMENTS, COMPUTATIONS, ETC.
            --------------------------- 

     (a)    Except as otherwise specifically provided herein, all payments
hereunder shall be made to the Administrative Agent in Dollars in immediately
available funds, without offset, deduction, counterclaim or withholding of any
kind, at the Administrative Agent's office specified in Section 9.1 not later
than 2:00 P.M. (Charlotte, North Carolina time) on the date when due. Payments
received after such time shall be deemed to have been received on the next
succeeding Business Day. The Borrower shall, at the time it makes any payment
under this Credit Agreement, specify to the Administrative Agent the Loans,
Fees, interest or other amounts payable by the Borrower hereunder to which such
payment is to be applied (and in the event that it fails so to specify, or if
such application would be inconsistent with the terms hereof, the Administrative
Agent shall distribute such payment to the Lenders in such manner as the
Administrative Agent may determine to be appropriate in respect of obligations
owing by the Borrower hereunder, subject to the terms of Section 3.12(a)). The
Administrative Agent will distribute such payments to such Lenders, if any such
payment is received prior to 12:00 Noon (Charlotte, North Carolina time) on a
Business Day in like funds as received prior to the end of such Business Day and
otherwise the Administrative Agent will distribute such payment to such Lenders
on the next succeeding Business Day. Whenever any payment hereunder shall be
stated to be due on a day which is not a Business Day, the due date thereof
shall be extended to the next succeeding Business Day (subject to accrual of
interest and Fees for the period of such extension), except that in the case of
Eurodollar Loans, if the extension would cause the payment to be made in the
next following calendar month, then such payment shall instead be made on the
next preceding Business Day. Except as expressly provided otherwise herein, all
computations of interest and fees shall be made on the basis of actual number of
days elapsed over a year of 360 days, except with respect to computation of
interest on Base Rate Loans which (unless the Base Rate is determined by
reference to the Federal Funds Rate) shall be calculated based on a year of 365
or 366 days, as appropriate. Interest shall accrue from and include the date of
borrowing, but exclude the date of payment.

     (b)    Allocation of Payments After Event of Default.  Notwithstanding any
            ---------------------------------------------
other provisions of this Credit Agreement to the contrary, after the occurrence
and during the continuance of an Event of Default, all amounts collected or
received by the Administrative Agent or any Lender on account of the Obligations
or any other amounts outstanding under any of the Credit Documents shall be paid
over or delivered as follows:

                                      18
<PAGE>
 
           FIRST, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation reasonable attorneys' fees) of the
     Administrative Agent in connection with enforcing the rights of the Lenders
     under the Credit Documents;

           SECOND, to payment of any fees owed to the Administrative Agent;

           THIRD, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation, reasonable attorneys' fees) of each
     of the Lenders in connection with enforcing its rights under the Credit
     Documents or otherwise with respect to the Obligations owing to such
     Lender;

           FOURTH, to the payment of all accrued interest and fees on or in
     respect of the Obligations;

           FIFTH, to the payment of the outstanding principal amount of the
     Obligations;

           SIXTH, to all other Obligations and other obligations which shall
     have become due and payable under the Credit Documents or otherwise and not
     repaid pursuant to clauses "FIRST" through "FIFTH" above; and

           SEVENTH, to the payment of the surplus, if any, to whoever may be
     lawfully entitled to receive such surplus.

In carrying out the foregoing, (i) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category; and (ii) each of the Lenders shall receive an amount equal
to its pro rata share (based on the proportion that the then outstanding
Obligations held by such Lender bears to the aggregate then outstanding
Obligations) of amounts available to be applied pursuant to clauses "THIRD",
"FOURTH", "FIFTH" and "SIXTH" above.

     (c)   Treatment. The Lenders agree that in the exercise of rights under
           ---------                                                         
Sections 3.6, 3.7, 3.8 and 3.9, they will accord the Borrower the treatment
generally accorded by the Lenders to similarly situated borrowers.

     3.15  EVIDENCE OF DEBT.
           ---------------- 

     (a)   Each Lender shall maintain an account or accounts evidencing each
Loan made by such Lender to the Borrower from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Credit Agreement. Each Lender will make reasonable efforts to
maintain the accuracy of its account or accounts and to promptly update its
account or accounts from time to time, as necessary.

     (b)   The Administrative Agent shall maintain the Register pursuant to
Section 9.3(c) hereof, and a subaccount for each Lender, in which Register and
subaccounts (taken together) shall be recorded (i) the amount, type and Interest
Period of each such Loan hereunder, (ii) the amount of any principal or interest
due and payable or to become due and payable to each Lender hereunder and (iii)
the amount of any sum received by the Administrative Agent hereunder from or for
the account of the Borrower and each Lender's share thereof. The Administrative
Agent will make reasonable efforts to

                                      19
<PAGE>
 
maintain the accuracy of the subaccounts referred to in the preceding sentence
and to promptly update such subaccounts from time to time, as necessary.

     (c)    The entries made in the accounts, Register and subaccounts
maintained pursuant to subsection (b) of this Section 3.15 (and, if consistent
with the entries of the Administrative Agent, subsection (a)) shall be prima
facie evidence of the existence and amounts of the obligations of the Borrower
therein recorded; provided, however, that the failure of any Lender or the
                  --------  -------                                       
Administrative Agent to maintain any such account, such Register or such
subaccount, as applicable, or any error therein, shall not in any manner affect
the obligation of the Borrower to repay the Loans made by such Lender in
accordance with the terms hereof.

 
                                   SECTION 4
                                   GUARANTY
                                   ---------

     4.1    THE GUARANTEE.
            -------------

     Each of the Guarantors hereby jointly and severally guarantees to each
Lender, to each Affiliate of a Lender that enters into a Hedging Agreement and
to the Administrative Agent as hereinafter provided the prompt payment of the
Guaranteed Obligations in full when due (whether at stated maturity, as a
mandatory prepayment, by acceleration, a mandatory cash collateralization or
otherwise) strictly in accordance with the terms thereof. The Guarantors hereby
further agree that if any of the Guaranteed Obligations are not paid in full
when due (whether at stated maturity, as a mandatory prepayment, by 
acceleration, as mandatory cash collateralization or otherwise and after giving
effect to any grace periods), the Guarantors will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration or otherwise and
after giving effect to any grace periods) in accordance with the terms of such
extension or renewal. This is a guaranty of payment and not of collection.

     Notwithstanding any provision to the contrary contained herein or in any
other of the Credit Documents or Hedging Agreements, to the extent the
obligations of a Guarantor shall be adjudicated to be invalid or unenforceable
for any reason (including, without limitation, because of any applicable state
or federal law relating to fraudulent conveyances or transfers) then the
obligations of each Guarantor hereunder shall be limited to the maximum amount
that is permissible under applicable law (whether federal or state and
including, without limitation, the Bankruptcy Code).

     4.2    OBLIGATIONS UNCONDITIONAL.
            -------------------------

     The obligations of the Guarantors under Section 4.1 hereof are joint and
several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Credit Documents or Hedging
Agreements, or any other agreement or instrument referred to therein, or any
substitution, release or exchange of any other guarantee of or security for any
of the Guaranteed Obligations, and, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section 4.2 that the obligations of the
Guarantors hereunder shall be absolute and unconditional under any and all
circumstances. Each

                                      20 
<PAGE>
 
Guarantor agrees that such Guarantor shall have no right of subrogation,
indemnity, reimbursement or contribution against the Borrower or any other
Guarantor of the Guaranteed Obligations for amounts paid under this Guaranty
until such time as the Lenders (and any Affiliates of Lenders entering into
Hedging Agreements) have been paid in full, all Commitments under the Credit
Agreement have been terminated and no Person or Governmental Authority shall
have any right to request any return or reimbursement of funds from the Lenders
in connection with monies received under the Credit Documents or Hedging
Agreements. Without limiting the generality of the foregoing, it is agreed that,
to the fullest extent permitted by law, the occurrence of any one or more of the
following shall not alter or impair the liability of any Guarantor hereunder
which shall remain absolute and unconditional as described above:

          (i)   at any time or from time to time, without notice to any
     Guarantor, the time for any performance of or compliance with any of the
     Guaranteed Obligations shall be extended, or such performance or compliance
     shall be waived;

          (ii)  any of the acts mentioned in any of the provisions of any of the
     Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be done or omitted;

          (iii) the maturity of any of the Guaranteed Obligations shall be
     accelerated, or any of the Guaranteed Obligations shall be modified,
     supplemented or amended in any respect, or any right under any of the
     Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be waived or any other guarantee of any of the Guaranteed Obligations or
     any security therefor shall be released or exchanged in whole or in part or
     otherwise dealt with;

          (iv)  any Lien granted to, or in favor of, the Administrative Agent or
     any Lender or Lenders as security for any of the Guaranteed Obligations
     shall fail to attach or be perfected or shall be released or discharged in
     whole or in part; or

          (v)   any of the Guaranteed Obligations shall be determined to be void
     or voidable (including, without limitation, for the benefit of any
     creditor of any Guarantor) or shall be subordinated to the claims of any
     Person (including, without limitation, any creditor of any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Administrative Agent or any Lender
exhaust any right, power or remedy or proceed against any Person under any of
the Credit Documents, any Hedging Agreement or any other agreement or instrument
referred to in the Credit Documents or Hedging Agreements, or against any other
Person under any other guarantee of, or security for, any of the Guaranteed
Obligations.
                 
     4.3  REINSTATEMENT.
          -------------

     The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Guaranteed Obligations is rescinded
or must be otherwise restored by any holder of any of the Guaranteed
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or

                                      21
<PAGE>
 
otherwise, and each Guarantor agrees that it will indemnify the Administrative
Agent and each Lender on demand for all reasonable costs and expenses
(including, without limitation, fees and expenses of counsel) incurred by the
Administrative Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

     4.4  CERTAIN ADDITIONAL WAIVERS.
          --------------------------

     Without limiting the generality of the provisions of this Section 4, each
Guarantor hereby specifically waives the benefits of N.C. Gen. Stat. (S)(S) 26-7
through 26-9, inclusive. Each Guarantor further agrees that such Guarantor shall
have no right of recourse to security for the Guaranteed Obligations, except
through the exercise of the rights of subrogation pursuant to Section 4.2.

     4.5  REMEDIES.
          -------- 

     The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Administrative Agent and the
Lenders, on the other hand, the Guaranteed Obligations may be declared to be
forthwith due and payable as provided in Section 7.2 hereof (and shall be deemed
to have become automatically due and payable in the circumstances provided in
said Section 7.2) for purposes of Section 4.1 hereof notwithstanding any stay,
injunction or other prohibition preventing such declaration (or preventing the
Guaranteed Obligations from becoming automatically due and payable) as against
any other Person and that, in the event of such declaration (or the Guaranteed
Obligations being deemed to have become automatically due and payable), the
Guaranteed Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors for purposes of said
Section 4.1.

     4.6  RIGHTS OF CONTRIBUTION.
          ----------------------

     The Guarantors hereby agree, as among themselves, that if any Guarantor
shall become an Excess Funding Guarantor (as defined below), each other
Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the
succeeding provisions of this Section 4.6), pay to such Excess Funding
Guarantor an amount equal to such Guarantor's Pro Rata Share (as defined below
and determined, for this purpose, without reference to the properties, assets,
liabilities and debts of such Excess Funding Guarantor) of such Excess Payment
(as defined below). The payment obligation of any Guarantor to any Excess
Funding Guarantor under this Section 4.6 shall be subordinate and subject in
right of payment to the prior payment in full of the obligations of such
Guarantor under the other provisions of this Section 4, and such Excess Funding
Guarantor shall not exercise any right or remedy with respect to such excess
until payment and satisfaction in full of all of such obligations. For purposes
hereof, (i) "Excess Funding Guarantor" shall mean, in respect of any obligations
             ------------------------
arising under the other provisions of this Section 4 (hereafter, the "Guarantied
                                                                      ----------
Obligations"), a Guarantor that has paid an amount in excess of its Pro Rata
- - -----------                                                               
Share of the Guarantied Obligations; (ii) "Excess Payment" shall mean, in 
                                           --------------
respect of any Guarantied Obligations, the amount paid by an Excess Funding
Guarantor in excess of its Pro Rata Share of such Guarantied Obligations; and
(iii) "Pro Rata Share", for the purposes of this Section 4.6, shall  mean, for
       -------------- 
any Guarantor, the ratio (expressed as a percentage) of (a) the amount by which
the aggregate present fair saleable value of all of its assets and properties
exceeds the amount of all debts and liabilities of such Guarantor (including
contingent, subordinated, unmatured, and unliquidated liabilities, but excluding
the obligations of such Guarantor

                                      22

<PAGE>
 
hereunder) to (b) the amount by which the aggregate present fair saleable value
of all assets and other properties of the Borrower and all of the Guarantors
exceeds the amount of all of the debts and liabilities (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding the
obligations of the Borrower and the Guarantors hereunder) of the Borrower and
all of the Guarantors, all as of the Closing Date (if any Guarantor becomes a
party hereto subsequent to the Closing Date, then for the purposes of this
Section 4.6 such subsequent Guarantor shall be deemed to have been a Guarantor
as of the Closing Date and the information pertaining to, and only pertaining 
to, such Guarantor as of the date such Guarantor became a Guarantor shall be
deemed true as of the Closing Date).

     4.7  CONTINUING GUARANTEE.
          --------------------

     The guarantee in this Section 4 is a continuing guarantee, and shall apply

                                             --------------------
Lender to act as specified herein and the other Credit Documents, and each such
Lender hereby authorizes the Administrative Agent as the Administrative Agent
for such Lender, to take such action on its behalf under the provisions of this
Credit Agreement and the other Credit Documents and to exercise such powers and
perform such duties as are expressly delegated by the terms hereof and of the
other Credit Documents, together with such other powers as are reasonably
incidental thereto. Each Lender further directs and authorizes the
Administrative Agent to execute releases (or similar agreements) to give effect
to the provisions of this Credit Agreement and the other Credit Documents,
including specifically without limitation the provisions of Section 3.16 hereof
and Section 8.4 of the Incorporated Covenants hereof.  Notwithstanding any
provision to the contrary elsewhere herein and in the other Credit Documents,
the Administrative Agent shall not have any duties or responsibilities, except
those expressly set forth herein and therein, or any fiduciary relationship with
any Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Credit Agreement or any of
the other Credit Documents, or shall otherwise exist against the Administrative
Agent. The provisions of this Section are solely for the benefit of the
Administrative Agent and the Lenders and none of the Credit Parties shall have
any rights as a third party beneficiary of the provisions hereof. In performing
its functions and duties under this Credit Agreement and the other Credit
Documents, the Administrative Agent shall act solely as Administrative Agent of
the Lenders and does not assume and shall not be deemed to have assumed any
obligation or relationship of agency or trust with or for any Credit Party or
any of their respective Affiliates.

     8.2   DELEGATION OF DUTIES.
           --------------------- 

     The Administrative Agent may execute any of its duties hereunder or under
the other Credit Documents by or through Administrative Agents or attorneys-in-
fact and shall be entitled to advice of counsel concerning all matters
pertaining to such duties. The Administrative Agent shall not be responsible
for the negligence or misconduct of any agents or attorneys-in-fact selected by
it with reasonable care.

     8.3   EXCULPATORY PROVISIONS.
           ---------------------- 

     The Administrative Agent and its officers, directors, employees, agents, 
attorneys-in-fact or affiliates shall not be (i) liable for any action lawfully
taken or omitted to be taken by it or such Person under or in connection
herewith or in connection with any of the other Credit Documents (except for its
or such Person's own gross negligence or willful misconduct), or (ii)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by any of the Credit Parties contained herein
or in any of the other Credit Documents or in any certificate, report,

                                       30

document, financial statement or other written or oral statement referred to or
provided for in, received by the Administrative Agent under or in connection
herewith or in connection with the other Credit Documents, or enforceability or
sufficiency therefor of any of the other Credit Documents, or for any failure of
any Credit Party to perform its obligations hereunder or thereunder. The
Administrative Agent shall not be responsible to any Lender for the
effectiveness, genuineness, validity, enforceability, collectibility or
sufficiency of this Credit Agreement, or any of the other Credit Documents or
for any representations, warranties, recitals or statements made herein or
therein or made by the Borrower or any Credit Party in any written or oral
statement or in any financial or other statements, instruments, reports,
certificates or any other documents in connection herewith or therewith
furnished or made by the Administrative Agent to the Lenders or by or on behalf
of the Credit Parties to the Administrative Agent or any Lender or be required
to ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained herein or therein or
as to the use of the proceeds of the Loans or the use of the Letters of Credit
or of the existence or possible existence of any Default or Event of Default or
to inspect the properties, books or records of the Credit Parties or any of
their respective Affiliates.

     8.4   RELIANCE ON COMMUNICATIONS.
           -------------------------- 

     The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to any of the Credit Parties, independent accountants and
other experts selected by the Administrative Agent with reasonable care). The
Administrative Agent may deem and treat the Lenders as the owner of their
respective interests hereunder for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent in accordance with Section 9.3(b) hereof. The
Administrative Agent shall be fully justified in failing or refusing to take
any action under this Credit Agreement or under any of the other Credit
Documents unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, hereunder or under any of the other Credit Documents in
accordance with a request of the Required Lenders (or to the extent specifically
provided in Section 9.6. all the Lenders) and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders
(including their successors and assigns).

     8.5   NOTICE OF DEFAULT.
           ----------------- 

     The Administrative Agent shall not be deemed to have knowledge or notice of
the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent has received notice from a Lender or a Credit Party
referring to the Credit Document, describing such Default or Event of Default
and stating that such notice is a "notice of default." In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
prompt notice thereof to the Lenders. The Administrative Agent shall take
such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required Lenders.

     8.6   NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.
           ------------------------------------------------------ 

                                      31

<PAGE>
 
     Each Lender expressly acknowledges that each of the Administrative Agent
and its officers, directors, employees, agents, attorneys-in-fact or affiliates
has not made any representations or warranties to it and that no act by the
Administrative Agent or any affiliate thereof hereinafter taken, including any
review of the affairs of any Credit Party or any of their respective Affiliates,
shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, assets, operations, property, financial and other conditions,
prospects and creditworthiness of the Borrower, the other Credit Parties or
their respective Affiliates and made its own decision to make its Loans
hereunder and enter into this Credit Agreement. Each Lender also represents that
it will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Credit Agreement, and to
make such investigation as it deems necessary to inform itself as to the
business, assets, operations, property, financial and other conditions,
prospects and creditworthiness of the Borrower, the other Credit Parties and
their respective Affiliates. Except for notices, reports and other documents
expressly required to be furnished to the Lenders by the Administrative Agent
hereunder, the Administrative Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the business,
operations, assets, property, financial or other conditions, prospects or
creditworthiness of the Borrower, the other Credit Parties or any of their
respective Affiliates which may come into the possession of the Administrative
Agent or any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

     8.7     INDEMNIFICATION.
             --------------- 

     The Lenders agree to indemnify the Agents in their capacity as such (to
the extent not reimbursed by the Borrower and without limiting the obligation
of the Borrower to do so), ratably according to their respective Commitments (or
if the Commitments have expired or been terminated, in accordance with the
respective principal amounts of outstanding Loans and Participation Interests of
the Lenders), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time (including without limitation at
any time following the final payment of all of the obligations of the Borrower
hereunder and under the other Credit Documents) be imposed on, incurred by or
asserted against the Agents in their capacity as such in any way relating to or
arising out of this Credit Agreement or the other Credit Documents or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agents
under or in connection with any of the foregoing; provided that no Lender shall
                                                  --------
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the gross negligence or willful misconduct of the
Agents. If any indemnity furnished to the Agents for any purpose shall, in the
opinion of such Agent, be insufficient or become impaired, the Agent may call
for additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity is furnished. The agreements in this
Section shall survive the repayment of the Loans, and other obligations under
the Credit Documents and the termination of the Commitments hereunder.

     8.8     ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.
             ------------------------------------------------ 

                                      32
<PAGE>
 
     The Administrative Agent and its affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Company,
the Borrower, its Subsidiaries or their respective Affiliates as though the
Administrative Agent were not the Administrative Agent hereunder. With respect
to the Loans made to and all obligations of the Borrower hereunder and under
the other Credit Documents, the Administrative Agent shall have the same rights
and powers under this Credit Agreement as any Lender and may exercise the same
as though it were not the Administrative Agent, and the terms "Lender" and
"Lenders" shall include the Administrative Agent in its individual capacity.

     8.9     SUCCESSOR ADMINISTRATIVE AGENT.
             ------------------------------ 

     The Administrative Agent may, at any time, resign upon 20 days' written
notice to the Lenders, and may be removed, upon show of cause, by the Required
Lenders upon 30 days' written notice to the Administrative Agent.  Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Administrative Agent. If no successor Administrative Agent shall
have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the notice of resignation or notice of
removal, as appropriate, then the retiring Administrative Agent shall select a
successor Administrative Agent provided such successor is a Lender hereunder or
a commercial bank organized or licensed under the laws of the United States of
America or of any State thereof and has a combined capital and surplus of at
least $400,000,000. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties obligations as Administrative Agent,
as appropriate, under this Credit Agreement and the other Credit Documents and
the provisions of this Section 8.9 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Credit Agreement.

     8.10    INTERCREDITOR AGREEMENTS.
             ------------------------- 

     (a)  The terms of the Excluded Receivables Transaction require the
execution of an Intercreditor Agreement substantially in the form of Schedule
                                                                     --------
8.10(a) (the "INTERCREDITOR AGREEMENT") as a condition to the grant of a
- - -------       ------------------------
security interest by the Borrower in inventory and accounts. By execution
hereof, each Lender hereby acknowledges, and agrees to be bound by, the terms of
the Intercreditor Agreement (including specifically, without limitation, the
provisions of Sections 6, 7 and 10(b) thereof), and further authorizes and
directs the Administrative Agent to enter into the Intercreditor Agreement on
its behalf.

    (b) In addition, inasmuch as the obligations under the Existing Credit
Agreement are secured by the same collateral as that securing the obligations
this Credit Agreement, an intercreditor agreement is required in order that the
respective obligations share in such collateral on a pari passu basis.  By
execution hereof, each Lender hereby acknowledges and agrees to be bound by the
terms of an Intercreditor Agreement in substantially the form of Schedule 8.10
                                                                 -------------

     9.2     RIGHT OF SET-OFF.
             ---------------- 

     In addition to any rights now or hereafter granted under applicable law or
otherwise, and not by way of limitation of any such rights, upon the occurrence
of an Event of Default, each Lender is authorized at any time and from time to
time, without presentment, demand, protest or other notice of any kind (all of
which rights being hereby expressly waived), to set-off and to appropriate and
apply any and all deposits (general or special) and any other indebtedness at
any time held or owing by such Lender (including, without limitation branches,
agencies or Affiliates of such Lender wherever located) to or for the credit or
the account of any Credit Party against obligations and liabilities of such
Person to such Lender hereunder, under the Notes the other Credit Documents or
otherwise, irrespective of whether such Lender shall have made any demand
hereunder and although such obligations, liabilities or claims, or any of them,
may be contingent or unmatured, and any such set-off shall be deemed to have
been made immediately upon the occurrence of an Event of Default even though
such charge is made or entered on the books of such Lender subsequent thereto.
Any Person purchasing a participation in the Loans and Commitments hereunder
pursuant to Section 3.13 or Section 9.3(d) may exercise all rights of set-off
with respect to its participation interest as fully as if such Person were a
Lender hereunder.

     9.3  BENEFIT OF AGREEMENT.
          -------------------- 

          (a)  Generally. This Credit Agreement shall be binding upon and inure
               ---------
     to the benefit of and be enforceable by the respective successors and
     assigns of the parties hereto; provided that none of the Credit Parties may
                                    --------
     assign or transfer any of its interests or obligations without prior
     written consent of the Lenders; provided further that the rights of each
                                     -------- -------
     Lender to transfer, assign or grant participations in its rights and/or
     obligations hereunder shall be limited as set forth in this Section 9.3,
     provided however that nothing herein shall prevent or prohibit any Lender
     --------
     from (i) pledging its Loans hereunder to a Federal Reserve Bank in support
     of borrowings made by such Lender from such Federal Reserve Bank, or (ii)
     granting assignments or selling participations in such Lender's Loans
     and/or Commitments hereunder to its parent company and/or to any Affiliate
     or Subsidiary of such Lender.

         (b) Assignments. Each Lender may assign all or a portion of its rights
             -----------                                                      
     and obligations hereunder, pursuant to an assignment agreement
     substantially in the form of Schedule 9.3(b), to (i) any Lender or any
                                  ---------------                          
     Affiliate or Subsidiary of a Lender, or (ii) any other commercial bank
     financial institution or "accredited investor" (as defined in Regulation D
     of the Securities and Exchange Commission) reasonably acceptable to the
     Administrative Agent; provided that (i) any such assignment (other than any
                           --------                                             
     assignment to an existing Lender) shall be in a minimum aggregate amount
     of $5,000,000 (or, if less, the remaining amount of the Commitment being
     assigned by such Lender) of the Commitments and in integral multiples of
     $1,000,000 above such amount and (ii) each such assignment shall be of a
     constant, not varying, percentage of all such Lender's rights and
     obligations under this Credit Agreement. Any assignment hereunder shall be
     effective upon delivery to the Administrative Agent of written notice of
     the assignment together with a transfer fee of $3,500 payable to the
     Administrative Agent for its own account from and after the later of (i)
     the effective date specified in the applicable assignment agreement and
     (ii) the date of recording of such assignment in the Register pursuant to
     the terms of subsection (c) below. The assigning Lender will give prompt
     notice to the Administrative Agent and the Borrower of any such

                                      35
<PAGE>
 
assignment. Upon the effectiveness of any such Assignment (and after notice to,
and (to the extent required pursuant to the terms hereof), with the consent of,
the Borrower and the Administrative Agent as provided herein), the assignee
shall become a "Lender" for all purposes of this Credit Agreement and the other
Credit Documents and, to the extent of such assignment, the assigning Lender
shall be relieved of its obligations hereunder to the extent of the Loans and
Commitment components being assigned. Along such lines the Borrower agrees that
upon any such assignment and surrender of the appropriate Note or Notes, it will
promptly provide to the assigning Lender and to the assignee separate promissory
notes in the amount of their respective interests substantially in the form of
the original Note (but with notation thereon that it is given in substitution
for and replacement of the original Note or any replacement notes thereof). By
executing and delivering an assignment agreement in accordance with this Section
9.3(b), the assigning Lender thereunder and the assignee thereunder shall be
deemed to confirm to and agree with each other and the other parties hereto as
follows: (i) such assigning Lender warrants that it is the legal and beneficial
owner of the interest being assigned thereby free and clear of any adverse
claim; (ii) except as set forth in clause (i) above, such assigning Lender makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Credit Agreement, any of the other Credit Documents or any other instrument or
document furnished pursuant hereto or thereto, or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Credit
Agreement, any of the other Credit Documents or any other instrument or document
furnished pursuant hereto or thereto or the financial condition of any Credit
Party or any of their respective Affiliates or the performance or observance by
any Credit Party of any of its obligations under this Credit Agreement, any of
the other Credit Documents or any other instrument or document furnished
pursuant hereto or thereto; (iii) such assignee represents and warrants that it
is legally authorized to enter into such assignment agreement; (iv) such
assignee confirms that it has received a copy of this Credit Agreement, the
other Credit Documents and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
assignment agreement; (v) such assignee will independently and without reliance
upon the Administrative Agent, such assigning Lender or any other Lender, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under this Credit Agreement and the other Credit Documents; (vi) such assignee
appoints and authorizes the Administrative Agent to take such action on its
behalf and to exercise such powers under this Credit Agreement or any other
Credit Document as are delegated to the Administrative Agent by the terms hereof
or thereof, together with such powers as are reasonably incidental thereto; and
(vii) such assignee agrees that it will perform in accordance with their terms
all the obligations which by the terms of this Credit Agreement and the other
Credit Documents are required to be performed by it as a Lender.

     (c)  Maintenance of Register. The Administrative Agent shall maintain at 
          -----------------------
one of its offices in Charlotte, North Carolina a copy of each Lender assignment
agreement delivered to it in accordance with the terms of subsection (b) above 
and a register for the recordation of the identity of the principal amount, type
and Interest Period of each Loan outstanding hereunder, the names, addresses and
the Commitments of the Lenders pursuant to the terms hereof from time to time 
(the "Register"). The Administrative Agent will make reasonable efforts to 
      --------
maintain the accuracy of the Register and to promptly update the Register from 
time to time, as necessary. The entries in the Register shall be conclusive in 
the absence of manifest

                                      36
<PAGE>
 
     error and the Borrower, the Administrative Agent and the Lenders may treat 
     each Person whose name is recorded in the Register pursuant to the terms 
     hereof as a Lender hereunder for all purposes of this Credit Agreement. The
     Register shall be available for inspection by the Borrower and each Lender,
     at any reasonable time and from time to time upon reasonable prior notice.

          (d)  Participations. Each Lender may sell, transfer, grant or assign
               --------------
     participations in all or any part of such Lender's interests and 
     obligations hereunder, provided that (i) such selling Lender shall remain a
                            --------
     "Lender" for all purposes under this Credit Agreement (such selling 
     Lender's obligations under the Credit Documents remaining unchanged) and 
     the participant shall not constitute a Lender hereunder, (ii) no such 
     participant shall have, or be granted, rights to approve any amendment or
     waiver relating to this Credit Agreement or the other Credit Documents 
     except to the extent any such amendment or waiver would (A) reduce the 
     principal of or rate of interest on or Fees in respect of any Loans or any 
     Letter of Credit in which the participant is participating, (B) postpone   
     the date fixed for any payment of principal (including extension of the 
     Termination Date or the date of any mandatory prepayment), interest or Fees
     in which the participant is participating, or (C) except as expressly
     provided in the Credit Documents, release all or substantially all of the
     collateral pledged to secure the Obligations hereunder or release all or
     substantially all of the Guarantors from the guaranty obligations
     hereunder, and (iii) sub-participations by the participant (except to an
     affiliate, parent company or affiliate of a parent company of the
     participant) shall be prohibited. In the case of any such participation,
     the participant shall not have any rights under this Credit Agreement or
     the other Credit Documents (the participant's rights against the selling
     Lender in respect of such participation to be those set forth in the

     No failure or delay on the part of the Administrative Agent or any Lender

Document and no course of dealing between the Administrative Agent or any Lender
and any of the Credit Parties shall operate as a waiver thereof, nor shall any 
single or partial exercise of any right, power or privilege hereunder or under 
any other Credit Document preclude any other or further exercise thereof or the 
exercise of any other right, power or privilege hereunder or thereunder. The 
rights and remedies provided herein are cumulative and not exclusive of any 
rights or remedies which the Administrative Agent or any Lender would otherwise 
have. No notice to or demand on any Credit Party in any case shall entitle the 
Borrower or any other Credit Party to any other or further notice or demand in

circumstances without notice or demand.

     Percentage of each Revolving Loan borrowing available to the Administrative
     Agent for the account of the Borrower as specified in Section 3.14(a), or
     in such other manner as the Administrative Agent may specify in writing, by
     2:00 P.M. (Charlotte, North Carolina time) on the date specified in the
     applicable Notice of Borrowing in Dollars and in funds immediately

     the amounts made available to the Administrative Agent by the Lenders and
     in like funds as received by the Administrative Agent.

     (c) Repayment.  The principal amount of all Revolving Loans shall be due
         ---------

          (i) Base Rate Loans.  During such periods as Revolving Loans shall be
              ---------------                                                  
     comprised in whole or in part of Base Rate Loans, such Base Rate Loans
     shall bear interest at a per annum rate equal to the Base Rate; and

          (ii) Eurodollar Loans.  During such periods as Revolving Loans shall
               ----------------                                               
     be comprised in whole or in part of Eurodollar Loans, such Eurodollar Loans
     shall bear interest at a per annum rate equal to the applicable Eurodollar
     Rate plus three quarters of one percent ( 3/4%).
          ----

executed Revolving Note in favor of each Lender.

maximum number of six (6) Eurodollar Loans outstanding at any time.  For
purposes hereof, 

                                       9
<PAGE>
 
Eurodollar Loans with separate or different Interest Periods will be considered
as separate Eurodollar Loans even if their Interest Periods expire on the same
date.

                 OTHER PROVISIONS RELATING TO CREDIT FACILITIES
                 ----------------------------------------------

     3.1  Default Rate.
          ------------ 

          Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable upon written demand by the Administrative Agent, at
a per annum rate 2% greater than the rate which would otherwise be applicable
(or if no rate is applicable, whether in respect of interest, fees or other
amounts, then 2% greater than the Base Rate).

     3.2  Extension and Conversion.
          ------------------------ 

          Subject to the terms of Section 5.3, the Borrower shall have the
option, on any Business Day, to extend existing Loans into a subsequent
permissible Interest Period or to convert Loans into Loans of another interest
rate type; provided, however, that (i) except as provided in Section 3.8,
           --------  -------                                             
Eurodollar Loans may be converted into Base Rate Loans only on the last day of
the Interest Period applicable thereto, (ii) Eurodollar Loans may be extended,
and Base Rate Loans may be converted into Eurodollar Loans, only if no Default
or Event of Default is in existence on the date of extension or conversion,
(iii) Loans extended as, or converted into, Eurodollar Loans shall be subject to
the terms of the definition of "Interest Period" set forth in Section 1.1 and
                                ---------------                              
shall be in such minimum amounts as provided in Section 2.1(b)(ii) , and (iv)
any request for extension or conversion of a Eurodollar Loan which shall fail to
specify an Interest Period shall be deemed to be a request for an Interest
Period of one month.  Each such extension or conversion shall be effected by the
Borrower by giving a Notice of Extension/Conversion substantially in the form of
                                                                                
Schedule 3.2 (or telephone notice promptly confirmed in writing) to the
- - ------------                                                           
Administrative Agent prior to 12:00 Noon (Charlotte, North Carolina time) on the
Business Day of, in the case of the conversion of a Eurodollar Loan into a Base
Rate Loan, and on the third Business Day prior to, in the case of the extension
of a Eurodollar Loan as, or conversion of a Base Rate Loan into, a Eurodollar
Loan, the date of the proposed extension or conversion, specifying the date of
the proposed extension or conversion, the Loans to be so extended or converted,
the types of Loans into which such Loans are to be converted and, if
appropriate, the applicable Interest Periods with respect thereto.  Each request
for extension or conversion shall be irrevocable and shall constitute a
representation and warranty by the Borrower of the matters specified in
subsections (a) through (e) of Section 5.3.  In the event the Borrower fails to
request extension or conversion of any Eurodollar Loan in accordance with this
Section, or any such conversion or extension is not permitted or required by
this Section, then such Eurodollar Loan shall be automatically converted into a
Base Rate Loan at the end of the Interest Period applicable thereto.  The
Administrative Agent shall give each Lender notice as promptly as practicable of
any such proposed extension or conversion affecting any Loan.

     3.3  Voluntary Prepayments.

Business Days' prior written notice to the Administrative Agent and must be
accompanied by payment of any amounts owing under Section 3.11, and (ii) partial
repayments shall be in minimum principal amounts of $1,000,000, in the case of
Eurodollar Loans, and $500,000, in the case of Base Rate Loans.

     3.4  Reductions in Commitments and Mandatory Prepayments.
          --------------------------------------------------- 

          (a) Voluntary Reduction in Revolving Commitment.  The Revolving
              -------------------------------------------                
Commitments may be terminated or permanently reduced in whole or in part upon
three (3) Business Days' prior written notice to the Administrative Agent,
                                                                          
provided that (i) after giving effect to any voluntary reduction the aggregate
- - --------                                                                      
amount of Obligations shall not exceed the lesser of (A) the Aggregate Revolving
Committed Amount, as reduced, or (B) until the Security Release Date relating to
inventory (but not thereafter), the Borrowing Base, and (ii) partial reductions
shall be in minimum principal amounts of $5,000,000, and in integral multiples
of $1,000,000 in excess thereof.

          (b) Mandatory Reductions in Revolving Commitments and Mandatory
              -----------------------------------------------------------
Prepayments.  The Revolving Commitments shall be automatically and permanently
- - -----------                                                                   
reduced (and prepayments shall be required to the extent that outstanding
Obligations exceed the respective Revolving Commitment, as so reduced), by the
amounts provided below:

               (i) Asset Dispositions.  An amount equal to one hundred percent
                   ------------------                                         
     (100%) of the Net Proceeds received from Asset Dispositions.

               (ii) Debt and Equity Transactions.  An amount equal to one
                    ----------------------------                         
     hundred percent (100%) of the Net Proceeds received from any Debt
     Transaction or Equity Transaction.

          (c)  Mandatory Prepayments, Etc.
               ---------------------------

               (i) If at any time the aggregate principal amount of Obligations
     hereunder shall exceed the lesser of (A) the Aggregate Revolving Committed
     Amount or (B) until the Security Release Date relating to inventory (but
     not thereafter), the Borrowing Base, the Borrower shall immediately make
     payment on the Revolving Loans hereunder in an amount sufficient to
     eliminate the deficiency.

               (ii) If at any time the Aggregate Revolving Committed Amount
     under the Existing Credit Agreement shall exceed the Obligations owing
     thereunder (that is, there is unused availability under the Existing Credit
     Agreement determined for purposes hereof without giving effect to any
     voluntary, optional or mandatory reduction in the Aggregate Revolving
     Committed Amount thereunder in effect on the Closing Date hereof, being
     $500,000,000), the Borrower shall immediately either (A) make payment on
     the Revolving Loans hereunder in an amount sufficient to reduce the
     Obligations outstanding hereunder to zero or (B) reborrow Revolving Loans
     (or have Letters of 

                                       11
<PAGE>
 
     Credit issued) under the Existing Credit Agreement in an amount sufficient
     to eliminate such excess.

               (iii)  The Borrower will make prepayment on the Revolving Loans
     hereunder in an amount equal to one hundred percent (100%) of the Net
     Proceeds received from any Securitization Transaction (including for
     purposes hereof any increase in aggregate Invested Amount relating to the
     Excluded Securitization Transaction above $285,000,000).

          (d) Application.  Unless otherwise specified by the Borrower,
              -----------                                              
prepayments made hereunder shall be applied first to Base Rate Loans, then to
Eurodollar Loans in direct order of Interest Period maturities.  Amounts prepaid
hereunder may be reborrowed in accordance with the provisions hereof.

          (e)  Mandatory Commitment Termination.  The Commitments hereunder
               --------------------------------                            
shall terminate on the Termination Date.

     3.5  Fees.
          ---- 

          (a)  Commitment Fee.  In consideration of the Revolving Commitments
               --------------                                                
hereunder, the Borrower agrees to pay to the Administrative Agent for the
ratable benefit of the Lenders a commitment fee (the "Commitment Fee") equal to
                                                      --------------           
22.5 basis points (.225%) per  annum on the average daily unused amount of the
Revolving Committed Amount for the applicable period from the Closing Date.  The
Commitment Fee shall be payable quarterly in arrears on the 15th day following
the last day of each calendar quarter for the immediately preceding quarter (or
portion thereof) beginning with the first such date to occur after the Closing
Date.

          (b)  Administrative Fees.  The Borrower agrees to pay to the
               -------------------                                    
Administrative Agent, for its own account, an annual administrative fee and such
other fees, if any, referred to in the Administrative Agent's Fee Letter
(collectively, the "Administrative Agent's Fees").
                    ---------------------------   

     3.6  Capital Adequacy.
          ---------------- 

          If any Lender has determined, after the date hereof, that the adoption
or the becoming effective of, or any change in, or any change by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's capital or assets as a consequence of its commitments or
obligations hereunder to a level below that which such Lender could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy), then,
upon notice from such Lender to the Borrower, the Borrower shall be obligated to
pay to such Lender such additional amount or amounts as will compensate such
Lender on an after-tax basis for such

                                       12
<PAGE>
 
reduction. Each determination by any such Lender of amounts owing under this
Section shall, absent manifest error, be conclusive and binding on the parties
hereto.

     3.7  Inability To Determine Interest Rate.
          ------------------------------------ 

     If prior to the first day of any Interest Period, the Administrative Agent
shall have determined (which determination shall be conclusive and binding upon
the Borrower absent manifest error) that, by reason of circumstances affecting
the relevant market, adequate and reasonable means do not exist for ascertaining
the Eurodollar Rate for such Interest Period, the Administrative Agent shall
give telecopy or telephonic notice thereof to the Borrower and the Lenders as
soon as practicable thereafter.  If such notice is given (a) any Eurodollar
Loans requested to be made on the first day of such Interest Period shall be
made as Base Rate Loans and (b) any Loans that were to have been converted on
the first day of such Interest Period to or continued as Eurodollar Loans shall
be converted to or continued as Base Rate Loans.  Until such notice has been
withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made
or continued as such, nor shall the Borrower have the right to convert Base Rate
Loans to Eurodollar Loans.

     3.8  Illegality.
          ---------- 

     Notwithstanding any other provision herein, if the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
occurring after the Closing Date shall make it unlawful for any Lender to make
or maintain Eurodollar Loans as contemplated by this Credit Agreement, (a) such
Lender shall promptly give written notice of such circumstances to the Borrower
and the Administrative Agent (which notice shall be withdrawn whenever such
circumstances no longer exist), (b) the commitment of such Lender hereunder to
make Eurodollar Loans, continue Eurodollar Loans as such and convert a Base Rate
Loan to Eurodollar Loans shall forthwith be canceled and, until such time as it
shall no longer be unlawful for such Lender to make or maintain Eurodollar
Loans, such Lender shall then have a commitment only to make a Base Rate Loan
when a Eurodollar Loan is requested and (c) such Lender's Loans then outstanding
as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans
on the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law.  If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrower shall pay to
such Lender such amounts, if any, as may be required pursuant to Section 3.11.

     3.9  Requirements of Law.
          ------------------- 

     If, after the date hereof, the adoption of or any change in any Requirement
of Law or in the interpretation or application thereof applicable to any Lender,
or compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority, in each
case made subsequent to the Closing Date (or, if later, the date on which such
Lender becomes a Lender):

               (a) shall subject such Lender to any tax of any kind whatsoever
     with respect to any Eurodollar Loans made by it or its obligation to make
     Eurodollar Loans, or change the basis of taxation of payments to such
     Lender in respect thereof (except for (i) 

                                       13
<PAGE>
 
     Non-Excluded Taxes covered by Section 3.10 (including Non-Excluded Taxes
     imposed solely by reason of any failure of such Lender to comply with its
     obligations under Section 3.10(b)) and (ii) changes in taxes measured by or
     imposed upon the overall net income, or franchise tax (imposed in lieu of
     such net income tax), of such Lender or its applicable lending office,
     branch, or any affiliate thereof));

               (b) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

               (c) shall impose on such Lender any other condition (excluding
     any tax of any kind whatsoever);

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, upon notice to the
Borrower from such Lender, through the Administrative Agent, in accordance
herewith, the Borrower shall be obligated to promptly pay such Lender, upon its
demand, any additional amounts necessary to compensate such Lender on an after-
tax basis for such increased cost or reduced amount receivable, provided that,
                                                                --------      
in any such case, the Borrower may elect to convert the Eurodollar Loans made by
such Lender hereunder to Base Rate Loans by giving the Administrative Agent at
least one Business Day's notice of such election, in which case the Borrower
shall promptly pay to such Lender, upon demand, without duplication, such
amounts, if any, as may be required pursuant to Section 3.11.  If any Lender
becomes entitled to claim any additional amounts pursuant to this subsection, it
shall provide prompt notice thereof to the Borrower, through the Administrative
Agent, certifying (x) that one of the events described in this paragraph 3.9 has
occurred and describing in reasonable detail the nature of such event, (y) as to
the increased cost or reduced amount resulting from such event and (z) as to the
additional amount demanded by such Lender and a reasonably detailed explanation
of the calculation thereof.  Such a certificate as to any additional amounts
payable pursuant to this subsection submitted by such Lender, through the
Administrative Agent, to the Borrower shall be conclusive and binding on the
parties hereto in the absence of manifest error.  This covenant shall survive
the termination of this Credit Agreement and the payment of the Loans and all
other amounts payable hereunder.

     3.10 Taxes.
          ----- 

     (a) Except as provided below in this subsection, all payments made by the
Borrower or any Guarantor under this Credit Agreement and any Notes shall be
made free and clear of, and without deduction or withholding for or on account
of, any present or future income, stamp or other taxes, levies, imposts, duties,
charges, fees, deductions or withholdings, now or hereafter imposed, levied,
collected, withheld or assessed by any court, or governmental body, agency or
other official, excluding taxes measured by or imposed upon the overall net
income of any Lender or its applicable lending office, or any branch or
affiliate thereof, and all franchise taxes, branch taxes, taxes on doing
business or taxes on the overall capital or net worth of any Lender or its
applicable lending office, or any branch or affiliate thereof, in each case
imposed in lieu of net 

                                       14
<PAGE>
 
income taxes, imposed: (i) by the jurisdiction under the laws of which such
Lender, applicable lending office, branch or affiliate is organized or is
located, or in which its principal executive office is located, or any nation
within which such jurisdiction is located or any political subdivision thereof;
or (ii) by reason of any connection between the jurisdiction imposing such tax
and such Lender, applicable lending office, branch or affiliate other than a
connection arising solely from such Lender having executed, delivered or
performed its obligations, or received payment under or enforced, this Credit
Agreement or any Notes. If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("Non-Excluded Taxes") are required 
                                            ------------------
to be withheld from any amounts payable to the Administrative Agent or any
Lender hereunder or under any Notes, (A) the amounts so payable to the
Administrative Agent or such Lender shall be increased to the extent necessary
to yield to the Administrative Agent or such Lender (after payment of all Non-
Excluded Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Credit Agreement and any Notes,
provided, however, that the Borrower shall be entitled to deduct and withhold
- - --------  -------                                                   
any Non-Excluded Taxes and shall not be required to increase any such amounts
payable to any Lender that is not organized under the laws of the United States
of America or a state thereof if such Lender fails to comply with the
requirements of paragraph (b) of this subsection whenever any Non-Excluded Taxes
are payable by the Borrower, and (B) as promptly as possible thereafter the
Borrower shall send to the Administrative Agent for its own account or for the
account of such Lender, as the case may be, a certified copy of an original
official receipt received by the Borrower showing payment thereof or other
evidence of remittance of Non-Excluded Taxes reasonably acceptable to the
Administrative Agent. If the Borrower fails to pay any Non-Excluded Taxes when
due to the appropriate taxing authority or fails to remit to the Administrative
Agent the required receipts or other required documentary evidence, the Borrower
shall indemnify the Administrative Agent and the Lenders for any incremental
taxes, interest or penalties that may become payable by the Administrative Agent
or any Lender as a result of any such failure. The agreements in this subsection
shall survive the termination of this Credit Agreement and the payment of the
Loans and all other amounts payable hereunder.

     (b) Each Lender that is not incorporated or organized under the laws of the
United States of America or a state thereof shall:

          (X)(i) on or before the date it becomes a Lender, deliver to the
     Borrower and the Administrative Agent (A) two (2) properly completed and
     duly executed copies of United States Internal Revenue Service Form 1001 or
     4224, or successor applicable form, as the case may be, certifying that it
     is entitled to receive payments under this Credit Agreement and any Notes
     without deduction or withholding of any United States federal income taxes
     and (B) an Internal Revenue Service Form W-8 or W-9, or successor
     applicable form, as the case may be, certifying that it is entitled to an
     exemption from United States backup withholding tax;

          (ii) deliver to the Borrower and the Administrative Agent two (2)
     further properly completed and duly executed copies of any such form or
     certification on or before the date that any such form or certification
     expires or becomes obsolete and after the occurrence of any event requiring
     a change in the most recent form previously delivered by it to the
     Borrower; and

                                       15
<PAGE>
 
          (iii)  obtain such extensions of time for filing and complete such
     forms or certifications as may reasonably be requested by the Borrower or
     the Administrative Agent; or

          (Y) in the case of any such Lender that is not a "bank" within the
     meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (i) on or
     before the date it becomes a Lender, deliver to the Borrower (for the
     benefit of the Borrower and the Administrative Agent) (A) a statement under
     penalties of perjury that it (1) is not a bank within the meaning of

     shareholder within the meaning of Section 881(c)(3)(B) of the Code, and (3)
     is not a controlled foreign corporation receiving interest from a related
     person within the meaning of Section 881(c)(3)(C) of the Code, and (B) two
     (2) properly completed and duly executed copies of Internal Revenue Service
     Form W-8, or successor applicable form certifying to such Lender's legal
     entitlement at the date of such certificate to an exemption from U.S.
     withholding tax under the provisions of Section 881(c) of the Internal
     Revenue Code with respect to payments to be made under this Credit
     Agreement and any Notes (ii) deliver to the Borrower and the Administrative
     Agent two (2) further properly completed and duly executed copies of such
     form on or before the date it expires or becomes obsolete and after the
     occurrence of any event requiring a change in the most recently provided
     form, (iii) if necessary, obtain any extensions of time reasonably
     requested by the Borrower or the Administrative Agent for filing and
     completing such forms, and (iv) agree, to the extent legally entitled to do
     so, upon reasonable request by the Borrower, to provide to the Borrower
     (for the benefit of the Borrower and the Administrative Agent) such other
     forms as may be reasonably required in order to establish the legal
     entitlement of such Lender to an exemption from withholding with respect to
     payments under this Credit Agreement and any Notes;

unless in any such case any change in treaty, law or regulation has occurred
after the date such Person becomes a Lender hereunder which renders all such
forms inapplicable or which would prevent such Lender from duly completing and
delivering any such form with respect to it and such Lender so advises the
Borrower and the Administrative Agent.  Each Person that shall become a Lender
or a participant of a Lender pursuant to subsection 9.3 shall and each Lender
shall, upon a change in its applicable lending office, upon the effectiveness of
the related transfer, be required to provide all of the forms, certifications
and statements required pursuant to this subsection, provided that in the case
                                                     --------                 
of a participant of a Lender the obligations of such participant of a Lender
pursuant to this subsection (b) shall be determined as if the participant of a
Lender were a Lender except that such participant of a Lender shall furnish all
such required forms, certifications and statements to the Lender from which the
related participation shall have been purchased.

     (c) If any Lender shall become aware that it is entitled to claim a refund
or credit (such credit to include any increase in any foreign tax credit) in
respect of any Non-Excluded Taxes (including any penalties or interest with
respect thereto) as to which it has been indemnified by the Borrower or with
respect to which the Borrower has paid increased amounts pursuant to this
Section 3.10, it shall promptly notify the Borrower of the availability of such
refund or credit and shall, within 30 days after receipt of a request by the
Borrower, apply for such refund or credit.  If any Lender receives a refund or
credit (such credit to include any increase in any foreign tax 

                                       16
<PAGE>
 
credit) in respect of any Non-Excluded Taxes as to which it has been indemnified
by the Borrower or with respect to which the Borrower has paid increased amounts
under this Section 3.10, it shall promptly notify the Borrower of such refund or
credit and shall, within 30 days after receipt of such refund or the benefit of
such credit (such benefit to include any reduction of the taxes for which the
Lender would otherwise be liable due to any increase in any foreign tax credit
available to such Lender) repay the amount of such refund or benefit of such
credit to the Borrower (to the extent of amounts that have been paid by the
Borrower under this Section 3.10 with respect to Non-Excluded Taxes giving rise
to such refund or credit), plus any interest received with respect thereto, net
or all reasonable out-of-pocket expenses of such Lender and without interest
(other than interest actually received from the relevant taxing authority or
other governmental authority with respect to such refund or credit); provided,
                                                                     -------- 
however, that the Borrower, upon the request of such Lender, agrees to return
- - -------                                                                      
the amount of such refund or benefit of such credit (plus interest) to such
Lender in the event such Lender is required to repay the amount of such refund
or benefit of such credit to the relevant taxing authority or other governmental
authority.

     (d) Each Lender represents that it is not participating in, and will not
participate in, a conduit financing arrangement within the meaning of Treas.
Reg. (S)1.881-3(a)(2)(iv) in connection with the Loans.

     3.11 Indemnity.
          --------- 

     The Borrower promises to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur (other
than through such Lender's gross negligence or willful misconduct) as a
consequence of (a) default by the Borrower in making a borrowing of, conversion
into or continuation of Eurodollar Loans after the Borrower has given a notice
requesting the same in accordance with the provisions of this Credit Agreement,
(b) default by the Borrower in making any prepayment of a Eurodollar Loan after
the Borrower has given a notice thereof in accordance with the provisions of
this Credit Agreement or (c) the making of a prepayment of Eurodollar Loans on a
day which is not the last day of an Interest Period with respect thereto.  With
respect to Eurodollar Loans, such indemnification may include an amount equal to
the excess, if any, of (i) the amount of interest which would have accrued on
the amount so prepaid, or not so borrowed, converted or continued, for the
period from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of the applicable Interest Period (or, in the case of a
failure to borrow, convert or continue, the Interest Period that would have
commenced on the date of such failure) in each case at the applicable rate of
interest for such Eurodollar Loans provided for herein (excluding, however, the
Applicable Percentage included therein, if any) over (ii) the amount of interest
(as reasonably determined by such Lender) which would have accrued to such
Lender on such amount by placing such amount on deposit for a comparable period
with leading banks in the interbank Eurodollar market.  The covenants of the
Borrower set forth in this Section 3.11 shall survive the termination of this
Credit Agreement and the payment of the Loans and all other amounts payable
hereunder.

     3.12 Pro Rata Treatment.
          ------------------ 

     Except to the extent otherwise provided herein:

                                       17
<PAGE>
 
     (a) Loans.  Each Loan, each payment or prepayment of principal of any Loan,
         -----                                                                  
each payment of interest on the Loans, each payment of Commitment Fees, each
reduction of the Revolving Committed Amount and each conversion or extension of
any Loan, shall be allocated pro rata among the Lenders in accordance with the
respective principal amounts of their outstanding Loans and Participation
Interests.

     (b) Advances.  Unless the Administrative Agent shall have been notified in
         --------                                                              
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its ratable share of such borrowing available to
the Administrative Agent, the Administrative Agent may assume that such Lender
is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount.  If such amount is not made available to
the Administrative Agent by such Lender within the time period specified
therefor hereunder, such Lender shall pay to the Administrative Agent, on
demand, such amount with interest thereon at a rate equal to the Federal Funds
Rate for the period until such Lender makes such amount immediately available to
the Administrative Agent.  A certificate of the Administrative Agent submitted
to any Lender with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error.

     3.13 Sharing of Payments.
          ------------------- 

     The Lenders agree among themselves that, in the event that any Lender shall
obtain payment in respect of any Loan or any other obligation owing to such
Lender under this Credit Agreement through the exercise of a right of setoff,
banker's lien or counterclaim, or pursuant to a secured claim under Section 506
of Title 11 of the United States Code or other security or interest arising
from, or in lieu of, such secured claim, received by such Lender under any
applicable bankruptcy, insolvency or other similar law or otherwise, or by any
other means, in excess of its pro rata share of such payment as provided for in
this Credit Agreement, such Lender shall promptly purchase from the other
Lenders a participation in such Loans, and other obligations in such amounts,
and make such other adjustments from time to time, as shall be equitable to the
end that all Lenders share such payment in accordance with their respective
ratable shares as provided for in this Credit Agreement.  The Lenders further
agree among themselves that if payment to a Lender obtained by such Lender
through the exercise of a right of setoff, banker's lien, counterclaim or other
event as aforesaid shall be rescinded or must otherwise be restored, each Lender
which shall have shared the benefit of such payment shall, by repurchase of a
participation theretofore sold, return its share of that benefit (together with
its share of any accrued interest payable with respect thereto) to each Lender
whose payment shall have been rescinded or otherwise restored.  The Borrower
agrees that any Lender so purchasing such a participation may, to the fullest
extent permitted by law, exercise all rights of payment, including setoff,
banker's lien or counterclaim, with respect to such participation as fully as if
such Lender were a holder of such Loan, or other obligation in the amount of
such participation.  Except as otherwise expressly provided in this Credit
Agreement, if any Lender or the Administrative Agent shall fail to remit to the
Administrative Agent or any other Lender an amount payable by such Lender or the
Administrative Agent to the Administrative Agent or such other Lender pursuant
to this Credit Agreement on the date when such amount is due, such payments
shall be made by the Administrative Agent or such Lender, as the case may be,
together with interest thereon for each date from the date such amount is due
until the date such amount is paid to the Administrative 

                                       18
<PAGE>
 
Agent or such other Lender at a rate per annum equal to the Federal Funds Rate.
If under any applicable bankruptcy, insolvency or other similar law, any Lender
receives a secured claim in lieu of a setoff to which this Section 3.13 applies,
such Lender shall, to the extent practicable, exercise its rights in respect of
such secured claim in a manner consistent with the rights of the Lenders under
this Section 3.13 to share in the benefits of any recovery on such secured
claim.

     3.14 Payments, Computations, Etc.
          ----------------------------

     (a) Except as otherwise specifically provided herein, all payments
hereunder shall be made to the Administrative Agent in Dollars in immediately
available funds, without offset, deduction, counterclaim or withholding of any
kind, at the Administrative Agent's office specified in Section 9.1 not later
than 2:00 P.M. (Charlotte, North Carolina time) on the date when due.  Payments
received after such time shall be deemed to have been received on the next
succeeding Business Day.  The Borrower shall, at the time it makes any payment
under this Credit Agreement, specify to the Administrative Agent the Loans,
Fees, interest or other amounts payable by the Borrower hereunder to which such
payment is to be applied (and in the event that it fails so to specify, or if
such application would be inconsistent with the terms hereof, the Administrative
Agent shall distribute such payment to the Lenders in such manner as the
Administrative Agent may determine to be appropriate in respect of obligations
owing by the Borrower hereunder, subject to the terms of Section 3.12(a)).  The
Administrative Agent will distribute such payments to such Lenders, if any such
payment is received prior to 12:00 Noon (Charlotte, North Carolina time) on a
Business Day in like funds as received prior to the end of such Business Day and
otherwise the Administrative Agent will distribute such payment to such Lenders
on the next succeeding Business Day.  Whenever any payment hereunder shall be
stated to be due on a day which is not a Business Day, the due date thereof
shall be extended to the next succeeding Business Day (subject to accrual of
interest and Fees for the period of such extension), except that in the case of
Eurodollar Loans, if the extension would cause the payment to be made in the
next following calendar month, then such payment shall instead be made on the
next preceding Business Day.  Except as expressly provided otherwise herein, all
computations of interest and fees shall be made on the basis of actual number of
days elapsed over a year of 360 days, except with respect to computation of
interest on Base Rate Loans which (unless the Base Rate is determined by
reference to the Federal Funds Rate) shall be calculated based on a year of 365
or 366 days, as appropriate.  Interest shall accrue from and include the date of
borrowing, but exclude the date of payment.

     (b)  Allocation of Payments After Event of Default.  Notwithstanding any
          ---------------------------------------------                      
other provisions of this Credit Agreement to the contrary, after the occurrence
and during the continuance of an Event of Default, all amounts collected or
received by the Administrative Agent or any Lender on account of the Obligations
or any other amounts  outstanding under any of the Credit Documents shall be
paid over or delivered as follows:

          FIRST, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation reasonable attorneys' fees) of the
     Administrative Agent in connection with enforcing the rights of the Lenders
     under the Credit Documents;

          SECOND, to payment of any fees owed to the Administrative Agent;

                                       19
<PAGE>
 
          THIRD, to the payment of all reasonable out-of-pocket costs and
     expenses (including without limitation, reasonable attorneys' fees) of each
     of the Lenders in connection with enforcing its rights under the Credit
     Documents or otherwise with respect to the Obligations owing to such
     Lender;

          FOURTH, to the payment of all accrued interest and fees on or in
     respect of the Obligations;

          FIFTH, to the payment of the outstanding principal amount of the
     Obligations;

          SIXTH, to all other Obligations and other obligations which shall have
     become due and payable under the Credit Documents or otherwise and not
     repaid pursuant to clauses "FIRST" through "FIFTH" above; and

          SEVENTH, to the payment of the surplus, if any, to whoever may be
     lawfully entitled to receive such surplus.

In carrying out the foregoing, (i) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category; and (ii) each of the Lenders shall receive an amount equal
to its pro rata share (based on the proportion that the then outstanding
Obligations held by such Lender bears to the aggregate then outstanding
Obligations) of amounts available to be applied pursuant to clauses "THIRD",
"FOURTH", "FIFTH" and "SIXTH" above.

     (c) Treatment.  The Lenders agree that in the exercise of rights under
         ---------                                                         
Sections 3.6, 3.7, 3.8 and 3.9, they will accord the Borrower the treatment
generally accorded by the Lenders to similarly situated borrowers.

     3.15 Evidence of Debt.
          ---------------- 

     (a) Each Lender shall maintain an account or accounts evidencing each Loan
made by such Lender to the Borrower from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time under
this Credit Agreement.  Each Lender will make reasonable efforts to maintain the
accuracy of its account or accounts and to promptly update its account or
accounts from time to time, as necessary.

     (b) The Administrative Agent shall maintain the Register pursuant to
Section 9.3(c) hereof, and a subaccount for each Lender, in which Register and
subaccounts (taken together) shall be recorded (i) the amount, type and Interest
Period of each such Loan hereunder, (ii) the amount of any principal or interest
due and payable or to become due and payable to each Lender hereunder and (iii)
the amount of any sum received by the Administrative Agent hereunder from or for
the account of the Borrower and each Lender's share thereof.  The Administrative
Agent will make reasonable efforts to maintain the accuracy of the subaccounts
referred to in the preceding sentence and to promptly update such subaccounts
from time to time, as necessary.

     (c) The entries made in the accounts, Register and subaccounts maintained
pursuant to subsection (b) of this Section 3.15 (and, if consistent with the
entries of the Administrative Agent, 

                                       20
<PAGE>
 
subsection (a)) shall be prima facie evidence of the existence and amounts of
the obligations of the Borrower therein recorded; provided, however, that the
                                                  --------  -------       
failure of any Lender or the Administrative Agent to maintain any such account,
such Register or such subaccount, as applicable, or any error therein, shall not
in any manner affect the obligation of the Borrower to repay the Loans made by
such Lender in accordance with the terms hereof.


                                   SECTION 4
                                    GUARANTY
                                    --------

     4.1  The Guarantee.
          ------------- 

     Each of the Guarantors hereby jointly and severally guarantees to each
Lender, to each Affiliate of a Lender that enters into a Hedging Agreement and
to the Administrative Agent as hereinafter provided the prompt payment of the
Guaranteed Obligations in full when due (whether at stated maturity, as a
mandatory prepayment, by acceleration, a mandatory cash collateralization or
otherwise) strictly in accordance with the terms thereof.  The Guarantors hereby
further agree that if any of the Guaranteed Obligations are not paid in full
when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as mandatory cash collateralization or otherwise and after giving
effect to any grace periods), the Guarantors will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the
case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, as a mandatory prepayment, by acceleration or otherwise and
after giving effect to any grace periods) in accordance with the terms of such
extension or renewal.  This is a guaranty of payment and not of collection.

     Notwithstanding any provision to the contrary contained herein or in any
other of the Credit Documents or Hedging Agreements, to the extent the
obligations of a Guarantor shall be adjudicated to be invalid or unenforceable
for any reason (including, without limitation, because of any applicable state
or federal law relating to fraudulent conveyances or transfers) then the
obligations of each Guarantor hereunder shall be limited to the maximum amount
that is permissible under applicable law (whether federal or state and
including, without limitation, the Bankruptcy Code).

     4.2  Obligations Unconditional.
          ------------------------- 

     The obligations of the Guarantors under Section 4.1 hereof are joint and
several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Credit Documents or Hedging
Agreements, or any other agreement or instrument referred to therein, or any
substitution, release or exchange of any other guarantee of or security for any
of the Guaranteed Obligations, and, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section 4.2 that the obligations of the
Guarantors hereunder shall be absolute and unconditional under any and all
circumstances.  Each Guarantor agrees that such Guarantor shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower or
any other Guarantor of the Guaranteed Obligations for amounts paid under this
Guaranty until such time as the Lenders (and 

                                       21
<PAGE>
 
any Affiliates of Lenders entering into Hedging Agreements) have been paid in
full, all Commitments under the Credit Agreement have been terminated and no
Person or Governmental Authority shall have any right to request any return or
reimbursement of funds from the Lenders in connection with monies received under
the Credit Documents or Hedging Agreements. Without limiting the generality of
the foregoing, it is agreed that, to the fullest extent permitted by law, the
occurrence of any one or more of the following shall not alter or impair the
liability of any Guarantor hereunder which shall remain absolute and
unconditional as described above:

          (i) at any time or from time to time, without notice to any Guarantor,
     the time for any performance of or compliance with any of the Guaranteed
     Obligations shall be extended, or such performance or compliance shall be
     waived;

          (ii) any of the acts mentioned in any of the provisions of any of the
     Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be done or omitted;

          (iii) the maturity of any of the Guaranteed Obligations shall be
     accelerated, or any of the Guaranteed Obligations shall be modified,
     supplemented or amended in any respect, or any right under any of the
     Credit Documents, any Hedging Agreement or any other agreement or
     instrument referred to in the Credit Documents or Hedging Agreements shall
     be waived or any other guarantee of any of the Guaranteed Obligations or
     any security therefor shall be released or exchanged in whole or in part or
     otherwise dealt with;

          (iv) any Lien granted to, or in favor of, the Administrative Agent or
     any Lender or Lenders as security for any of the Guaranteed Obligations
     shall fail to attach or be perfected or shall be released or discharged in
     whole or in part; or

          (v) any of the Guaranteed Obligations shall be determined to be void
     or voidable (including, without limitation, for the benefit of any creditor
     of any Guarantor) or shall be subordinated to the claims of any Person
     (including, without limitation, any creditor of any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Administrative Agent or any Lender
exhaust any right, power or remedy or proceed against any Person under any of
the Credit Documents, any Hedging Agreement or any other agreement or instrument
referred to in the Credit Documents or Hedging Agreements, or against any other
Person under any other guarantee of, or security for, any of the Guaranteed
Obligations.

     4.3  Reinstatement.
          ------------- 

     The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Guaranteed Obligations is rescinded
or must be otherwise restored by any holder of any of the Guaranteed
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Administrative Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, fees and 

                                       22
<PAGE>
 
expenses of counsel) incurred by the Administrative Agent or such Lender in
connection with such rescission or restoration, including any such costs and
expenses incurred in defending against any claim alleging that such payment
constituted a preference, fraudulent transfer or similar payment under any
bankruptcy, insolvency or similar law.

     4.4  Certain Additional Waivers.
          -------------------------- 

     Without limiting the generality of the provisions of this Section 4, each
Guarantor hereby specifically waives the benefits of N.C. Gen. Stat. (S)(S) 26-7
through 26-9, inclusive.  Each Guarantor further agrees that such Guarantor
shall have no right of recourse to security for the Guaranteed Obligations,
except through the exercise of the rights of subrogation pursuant to Section
4.2.

     4.5  Remedies.
          -------- 

     The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Administrative Agent and the
Lenders, on the other hand, the Guaranteed Obligations may be declared to be
forthwith due and payable as provided in Section 7.2 hereof (and shall be deemed
to have become automatically due and payable in the circumstances provided in
said Section 7.2) for purposes of Section 4.1 hereof notwithstanding any stay,
injunction or other prohibition preventing such declaration (or preventing the
Guaranteed Obligations from becoming automatically due and payable) as against
any other Person and that, in the event of such declaration (or the Guaranteed
Obligations being deemed to have become automatically due and payable), the
Guaranteed Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors for purposes of said
Section 4.1.

     4.6  Rights of Contribution.
          ---------------------- 

     The Guarantors hereby agree, as among themselves, that if any Guarantor
shall become an Excess Funding Guarantor (as defined below), each other
Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the
succeeding provisions of this Section 4.6), pay to such Excess Funding Guarantor
an amount equal to such Guarantor's Pro Rata Share (as defined below and
determined, for this purpose, without reference to the properties, assets,
liabilities and debts of such Excess Funding Guarantor) of such Excess Payment
(as defined below).  The payment obligation of any Guarantor to any Excess
Funding Guarantor under this Section 4.6 shall be subordinate and subject in
right of payment to the prior payment in full of the obligations of such
Guarantor under the other provisions of this Section 4, and such Excess Funding
Guarantor shall not exercise any right or remedy with respect to such excess
until payment and satisfaction in full of all of such obligations.  For purposes
hereof, (i) "Excess Funding Guarantor" shall mean, in respect of any obligations
             ------------------------                                           
arising under the other provisions of this Section 4 (hereafter, the "Guarantied
                                                                      ----------
Obligations"), a Guarantor that has paid an amount in excess of its Pro Rata
- - -----------                                                                 
Share of the Guarantied Obligations; (ii) "Excess Payment" shall mean, in
                                           --------------                
respect of any Guarantied Obligations, the amount paid by an Excess Funding
Guarantor in excess of its Pro Rata Share of such Guarantied Obligations; and
(iii) "Pro Rata Share", for the purposes of this Section 4.6, shall mean, for
       --------------                                                        
any Guarantor, the ratio (expressed as a percentage) of (a) the amount by which

    obligations of any and every kind owing by the Credit Parties to the
    Administrative Agent and/or any of the Lenders hereunder to be due whereupon

Loans, all accrued interest in respect thereof, all accrued and unpaid Fees and
other indebtedness or obligations owing to the Administrative Agent and/or any
of the Lenders hereunder automatically shall immediately become due and payable
without presentment, demand, protest or the giving of any notice or other action
by the Administrative Agent or the Lenders, all of which are hereby waived by
the Credit Parties.

                               -----------------

     8.1  Appointment.
          ----------- 

     Each Lender hereby designates and appoints NationsBank, N.A. as
administrative agent (in such capacity, the "Administrative Agent") of such
                                             --------------------          
Lender to act as specified herein and the other Credit Documents, and each such
Lender hereby authorizes the Administrative Agent as the Administrative Agent
for such Lender, to take such action on its behalf under the provisions of this
Credit Agreement and the other Credit Documents and to exercise such powers and
perform such duties as are expressly delegated by the terms hereof and of the
other Credit Documents, together with such other powers as are reasonably
incidental thereto. Each Lender further directs and authorizes the
Administrative Agent to execute releases (or similar agreements) to give effect
to the provisions of this Credit Agreement and the other Credit Documents,
including specifically without limitation the provisions of Section 3.16 hereof
and Section 8.4 of the Incorporated Covenants hereof.  Notwithstanding any
provision to the contrary elsewhere herein and in the other Credit Documents,
the Administrative Agent shall not have any duties or responsibilities, except
those expressly set forth herein and therein, or any fiduciary relationship with
any Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Credit Agreement or any of
the other Credit Documents, or shall otherwise exist against the Administrative
Agent.  The provisions of this Section are solely for the benefit of the
Administrative Agent and the Lenders and none of the Credit Parties shall have
any rights as a third party beneficiary of the provisions hereof.  In performing
its functions and duties under this Credit Agreement and the other Credit
Documents, the Administrative Agent shall act solely as Administrative Agent of
the Lenders and does not assume and shall not be deemed to have assumed any
obligation or relationship of agency or trust with or for any Credit Party or
any of their respective Affiliates.

     8.2  Delegation of Duties.
          -------------------- 

     The Administrative Agent may execute any of its duties hereunder or under
the other Credit Documents by or through Administrative Agents or attorneys-in-
fact and shall be entitled to advice of counsel concerning all matters
pertaining to such duties.  The Administrative Agent shall not be responsible
for the negligence or misconduct of any agents or attorneys-in-fact selected by
it with reasonable care.

     8.3  Exculpatory Provisions.
          ---------------------- 

     The Administrative Agent and its officers, directors, employees, agents,
attorneys-in-fact or affiliates shall not be (i) liable for any action lawfully
taken or omitted to be taken by it or such Person under or in connection
herewith or in connection with any of the other Credit Documents (except for its
or such Person's own gross negligence or willful misconduct), or (ii)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by any of the Credit Parties contained herein
or in any of the other Credit Documents or in any certificate, report, document,
financial statement or other written or oral statement referred to or provided
for in, or received by the Administrative Agent under or in connection herewith
or in connection with the other Credit Documents, or enforceability or
sufficiency therefor of any of the other Credit Documents, or for any failure of
any Credit Party to perform its obligations hereunder or thereunder.  The
Administrative Agent shall not be responsible to any Lender for the
effectiveness, genuineness, validity, enforceability, collectibility or
sufficiency of this Credit Agreement, or any of the other Credit Documents or
for any representations, warranties, recitals or statements made herein or
therein or made by the Borrower or any Credit Party in any written or oral
statement or in any financial or other statements, instruments, reports,
certificates or any other documents in connection herewith or therewith
furnished or made by the Administrative Agent to the Lenders or by or on behalf
of the Credit Parties to the Administrative Agent or any Lender or be required
to ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained herein or therein or
as to the use of the proceeds of the Loans or the use of the Letters of Credit
or of the existence or possible existence of any Default or Event of Default or
to inspect the properties, books or records of the Credit Parties or any of
their respective Affiliates.

     8.4  Reliance on Communications.
          -------------------------- 

     The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to any of the Credit Parties, independent accountants and
other experts selected by the Administrative Agent with reasonable care).  The
Administrative Agent may deem and treat the Lenders as the owner of their
respective interests hereunder for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent in accordance with Section 9.3(b) hereof.  The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Credit Agreement or under any of the other Credit Documents
unless it shall first receive such advice or concurrence of the Required Lenders
as it 

                                       32
<PAGE>
 
deems appropriate or it shall first be indemnified to its satisfaction by the
Lenders against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action. The Administrative Agent
shall in all cases be fully protected in acting, or in refraining from acting,
hereunder or under any of the other Credit Documents in accordance with a
request of the Required Lenders (or to the extent specifically provided in
Section 9.6, all the Lenders) and such request and any action taken or failure
to act pursuant thereto shall be binding upon all the Lenders (including their
successors and assigns).

     8.5  Notice of Default.
          ----------------- 

     The Administrative Agent shall not be deemed to have knowledge or notice of
the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent has received notice from a Lender or a Credit Party
referring to the Credit Document, describing such Default or Event of Default
and stating that such notice is a "notice of default."  In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
prompt notice thereof to the Lenders.  The Administrative Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders.

     8.6  Non-Reliance on Administrative Agent and Other Lenders.
          ------------------------------------------------------ 

     Each Lender expressly acknowledges that each of the Administrative Agent
and its officers, directors, employees, agents, attorneys-in-fact or affiliates
has not made any representations or warranties to it and that no act by the
Administrative Agent or any affiliate thereof hereinafter taken, including any
review of the affairs of any Credit Party or any of their respective Affiliates,
shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender.  Each Lender represents to the
Administrative Agent that it has, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, assets, operations, property, financial and
other conditions, prospects and creditworthiness of the Borrower, the other
Credit Parties or their respective Affiliates and made its own decision to make
its Loans hereunder and enter into this Credit Agreement.  Each Lender also
represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Credit Agreement, and to make such investigation as it deems necessary to
inform itself as to the business, assets, operations, property, financial and
other conditions, prospects and creditworthiness of the Borrower, the other
Credit Parties and their respective Affiliates.  Except for notices, reports and
other documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, assets, property, financial or other
conditions, prospects or creditworthiness of the Borrower, the other Credit
Parties or any of their respective Affiliates which may come into the possession
of the Administrative Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or affiliates.

     8.7  Indemnification.
          --------------- 

                                       33
<PAGE>
 
     The Lenders agree to indemnify the Agents in their capacity as such (to the
extent not reimbursed by the Borrower and without limiting the obligation of the
Borrower to do so), ratably according to their respective Commitments (or if the
Commitments have expired or been terminated, in accordance with the respective
principal amounts of outstanding Loans and Participation Interests of the
Lenders), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time (including without limitation at
any time following the final payment of all of the obligations of the Borrower
hereunder and under the other Credit Documents) be imposed on, incurred by or
asserted against the Agents in their capacity as such in any way relating to or
arising out of this Credit Agreement or the other Credit Documents or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Agents
under or in connection with any of the foregoing; provided that no Lender shall
                                                  --------                     
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the gross negligence or willful misconduct of the
Agents.  If any indemnity furnished to the Agents for any purpose shall, in the
opinion of such Agent, be insufficient or become impaired, the Agent may call
for additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity is furnished.  The agreements in this
Section shall survive the repayment of the Loans, and other obligations under
the Credit Documents and the termination of the Commitments hereunder.

     8.8  Administrative Agent in its Individual Capacity.
          ----------------------------------------------- 

     The Administrative Agent and its affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Company, the
Borrower, its Subsidiaries or their respective Affiliates as though the
Administrative Agent were not the Administrative Agent hereunder.  With respect
to the Loans made to and all obligations of the Borrower hereunder and under the
other Credit Documents, the Administrative Agent shall have the same rights and
powers under this Credit Agreement as any Lender and may exercise the same as
though it were not the Administrative Agent, and the terms "Lender" and
"Lenders" shall include the Administrative Agent in its individual capacity.

     8.9  Successor Administrative Agent.
          ------------------------------ 

     The Administrative Agent may, at any time, resign upon 20 days' written
notice to the Lenders, and may be removed, upon show of cause, by the Required
Lenders upon 30 days' written notice to the Administrative Agent.  Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Administrative Agent.  If no successor Administrative Agent shall have
been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the notice of resignation or notice of
removal, as appropriate, then the retiring Administrative Agent shall select a
successor Administrative Agent provided such successor is a Lender hereunder or
a commercial bank organized or licensed under the laws of the United States of
America or of any State thereof and has a combined capital and surplus of at
least $400,000,000.  Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations as 

                                       34
<PAGE>
 
Administrative Agent, as appropriate, under this Credit Agreement and the other
Credit Documents and the provisions of this Section 8.9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Credit Agreement.

     8.10 Intercreditor Agreements.
          ------------------------ 

     (a)  The terms of the Excluded Receivables Transaction require the
execution of an Intercreditor Agreement substantially in the form of Schedule
                                                                     --------

- - -------       -----------------------                                   
security interest by the Borrower in inventory and accounts.  By execution
hereof, each Lender hereby acknowledges, and agrees to be bound by, the terms of
the Intercreditor Agreement (including specifically, without limitation, the
provisions of Sections 6, 7 and 10(b) thereof), and further authorizes and
directs the Administrative Agent to enter into the Intercreditor Agreement on
its behalf.

     (b) In addition, inasmuch as the obligations under the Existing Credit
Agreement are secured by the same collateral as that securing the obligations
this Credit Agreement, an intercreditor agreement is required in order that the
respective obligations share in such collateral on a pari passu basis.  By
execution hereof, each Lender hereby acknowledges and agrees to be bound by the
terms of an Intercreditor Agreement in substantially the form of Schedule
                                                                 --------

     9.2  Right of Set-Off.
          ---------------- 

     In addition to any rights now or hereafter granted under applicable law or
otherwise, and not by way of limitation of any such rights, upon the occurrence
of an Event of Default, each Lender is authorized at any time and from time to
time, without presentment, demand, protest or other notice of any kind (all of
which rights being hereby expressly waived), to set-off and to appropriate and
apply any and all deposits (general or special) and any other indebtedness at
any time held or owing by such Lender (including, without limitation branches,
agencies or Affiliates of such Lender wherever located) to or for the credit or
the account of any Credit Party against obligations and liabilities of such
Person to such Lender hereunder, under the Notes, the other Credit Documents or
otherwise, irrespective of whether such Lender shall have made any demand
hereunder and although such obligations, liabilities or claims, or any of them,
may be contingent or unmatured, and any such set-off shall be deemed to have
been made immediately upon the occurrence of an Event of Default even though
such charge is made or entered on the books of such Lender subsequent thereto.
Any Person purchasing a participation in the Loans and Commitments hereunder
pursuant to Section 3.13 or Section 9.3(d) may exercise all rights of set-off
with respect to its participation interest as fully as if such Person were a
Lender hereunder.

     9.3  Benefit of Agreement.

          (a) Generally.  This Credit Agreement shall be binding upon and inure
              ---------                                                        
     to the benefit of and be enforceable by the respective successors and
     assigns of the parties hereto; provided that none of the Credit Parties may

     assign or transfer any of its interests or obligations without prior
     written consent of the Lenders; provided   
                                     --------   

                                       36
<PAGE>
 
     further that the rights of each Lender to transfer, assign or grant 
     -------                        
     participations in its rights and/or obligations hereunder shall be limited
     as set forth in this Section 9.3, provided however that nothing herein 
                                       -------- 
     shall prevent or prohibit any Lender from (i) pledging its Loans hereunder
     to a Federal Reserve Bank in support of borrowings made by such Lender from
     such Federal Reserve Bank, or (ii) granting assignments or selling
     participations in such Lender's Loans and/or Commitments hereunder to its
     parent company and/or to any Affiliate or Subsidiary of such Lender.

          (b) Assignments.  Each Lender may assign all or a portion of its
              -----------                                                 
     rights and obligations hereunder, pursuant to an assignment agreement
     substantially in the form of Schedule 9.3(b), to (i) any Lender or any
                                  ---------------                          
     Affiliate or Subsidiary of a Lender, or (ii) any other commercial bank,
     financial institution or "accredited investor" (as defined in Regulation D
     of the Securities and Exchange Commission) reasonably acceptable to the
     Administrative Agent; provided that (i) any such assignment (other than any
                           --------                                             
     assignment to an existing Lender) shall be in a minimum aggregate amount of
     $5,000,000 (or, if less, the remaining amount of the Commitment being
     assigned by such Lender) of the Commitments and in integral multiples of
     $1,000,000 above such amount and (ii) each such assignment shall be of a
     constant, not varying, percentage of all such Lender's rights and
     obligations under this Credit Agreement.  Any assignment hereunder shall be
     effective upon delivery to the Administrative Agent of written notice of
     the assignment together with a transfer fee of $3,500 payable to the
     Administrative Agent for its own account from and after the later of (i)
     the effective date specified in the applicable assignment agreement and
     (ii) the date of recording of such assignment in the Register pursuant to
     the terms of subsection (c) below.  The assigning Lender will give prompt
     notice to the Administrative Agent and the Borrower of any such assignment.
     Upon the effectiveness of any such Assignment (and after notice to, and (to
     the extent required pursuant to the terms hereof), with the consent of, the
     Borrower and the Administrative Agent as provided herein), the assignee
     shall become a "Lender" for all purposes of this Credit Agreement and the
     other Credit Documents and, to the extent of such assignment, the assigning
     Lender shall be relieved of its obligations hereunder to the extent of the
     Loans and Commitment components being assigned.  Along such lines the
     Borrower agrees that upon any such assignment and surrender of the
     appropriate Note or Notes, it will promptly provide to the assigning Lender
     and to the assignee separate promissory notes in the amount of their
     respective interests substantially in the form of the original Note (but
     with notation thereon that it is given in substitution for and replacement
     of the original Note or any replacement notes thereof).  By executing and
     delivering an assignment agreement in accordance with this Section 9.3(b),
     the assigning Lender thereunder and the assignee thereunder shall be deemed
     to confirm to and agree with each other and the other parties hereto as
     follows: (i) such assigning Lender warrants that it is the legal and
     beneficial owner of the interest being assigned thereby free and clear of
     any adverse claim; (ii) except as set forth in clause (i) above, such

     that it will perform in accordance with their terms all the obligations
     which by the terms of this Credit Agreement and the other Credit Documents

              -----------------------                                          
     at one of its offices in Charlotte, North Carolina a copy of each Lender
     assignment agreement delivered to it in accordance with the terms of
     subsection (b) above and a register for the recordation of the identity of
     the principal amount, type and Interest Period of each Loan outstanding
     hereunder, the names, addresses and the Commitments of the Lenders pursuant
     to the terms hereof from time to time (the "Register").  The Administrative
                                                 --------                       
     Agent will make reasonable efforts to maintain the accuracy of the Register
     and to promptly update the Register from time to time, as necessary.  The
     entries in the Register shall be conclusive in the absence of manifest
     error and the Borrower, the Administrative Agent and the Lenders may treat
     each Person whose name is recorded in the Register pursuant to the terms
     hereof as a Lender hereunder for all purposes of this Credit Agreement.
     The Register shall be available for inspection by the Borrower and each
     Lender, at any reasonable time and from time to time upon reasonable prior
     notice.

          (d) Participations.  Each Lender may sell, transfer, grant or assign
              --------------                                                  
     participations in all or any part of such Lender's interests and
     obligations hereunder; provided that (i) such selling Lender shall remain a
                            --------                                            
     "Lender" for all purposes under this Credit Agreement (such selling
     Lender's obligations under the Credit Documents remaining unchanged) and
     the participant shall not constitute a Lender hereunder, (ii) no such
     participant shall have, or be granted, rights to approve any amendment or
     waiver relating to this Credit Agreement or the other Credit Documents
     except to the extent any such amendment or waiver would (A) reduce the
     principal of or rate of interest on or Fees in respect of any Loans or any
     Letter of Credit in which the participant is participating, (B) postpone
     the date fixed for any payment of principal (including extension of the
     Termination Date or the date of any mandatory prepayment), interest or Fees
     in which the participant is participating, or (C) except as expressly
     provided in the Credit Documents, release all or substantially all of the
     collateral pledged to secure the Obligations hereunder or release all or
     substantially all of the Guarantors from the guaranty obligations

                                       38
<PAGE>
 
     hereunder, and (iii) sub-participations by the participant (except to an
     affiliate, parent company or affiliate of a parent company of the
     participant) shall be prohibited.  In the case of any such participation,
     the participant shall not have any rights under this Credit Agreement or
     the other Credit Documents (the participant's rights against the selling
     Lender in respect of such participation to be those set forth in the
     participation agreement with such Lender creating such participation) and
     all amounts payable by the Borrower hereunder shall be determined as if
     such Lender had not sold such participation, provided, however, that such
                                                  --------                    
     participant shall be entitled to receive the benefit of additional amounts
     under Sections 3.6, 3.9, 3.10 and 3.11 on the same basis as if it were a
     Lender.

     9.4  No Waiver; Remedies Cumulative.
          ------------------------------ 

     No failure or delay on the part of the Administrative Agent or any Lender
in exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between the Administrative Agent or any Lender
and any of the Credit Parties shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder or under
any other Credit Document preclude any other or further exercise thereof or the
exercise of any other right, power or privilege hereunder or thereunder.  The
rights and remedies provided herein are cumulative and not exclusive of any
rights or remedies which the Administrative Agent or any Lender would otherwise
have.  No notice to or demand on any Credit Party in any case shall entitle the
Borrower or any other Credit Party to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Administrative Agent or the Lenders to any other or further action in any
circumstances without notice or demand.

     9.5  Payment of Expenses, etc.
          ------------------------ 

     The Borrower agrees to:  (i) pay all reasonable out-of-pocket costs and
expenses (A) of the Administrative Agent in connection with the negotiation,
preparation, execution and delivery of this Credit Agreement and the other
Credit Documents and the documents and instruments referred to therein
(including, without limitation, the reasonable fees and expenses of Moore & Van
Allen, PLLC, special counsel to the Administrative Agent) and any amendment,
waiver or consent relating hereto and thereto including, but not limited to, any
such amendments, waivers or consents resulting from or related to any work-out,
renegotiation or restructure relating to the performance by the Credit Parties
under this Credit Agreement and (B) of the Administrative Agent and the Lenders
in connection with enforcement of or preservation of rights under the Credit
Documents and the documents and instruments referred to therein (including,
without limitation, in connection with any such enforcement, the reasonable fees
and disbursements of counsel for the Administrative Agent and each of the
Lenders); (ii) pay and hold each of the Lenders harmless from and against any
and all present and future stamp and other similar taxes with respect to the
foregoing matters and save each of the Lenders harmless from and against any and
all liabilities with respect to or resulting from any delay or omission (other
than to the extent attributable to such Lender) to pay such taxes; and (iii)
indemnify each Lender, its officers, directors, employees, representatives and
Administrative Agents from and hold each of them harmless against any and all
losses, liabilities, claims, damages or reasonable expenses incurred by any of
them as a result of, or arising out of, or in any way related to, or by reason
of (A) any investigation, litigation or other proceeding (whether or not any
Lender is a party thereto) related 

                                       39
<PAGE>
 
to the entering into and/or performance of any Credit Document or the use of
proceeds of any Loans (including other extensions of credit) hereunder or the
consummation of any other transactions contemplated in any Credit Document,
including, without limitation, the reasonable fees and disbursements of counsel
incurred in connection with any such investigation, litigation or other
proceeding (other than investigations, litigation or other proceedings relating
solely to claims between or among the Lenders) or (B) the presence or Release of
any Materials of Environmental Concern at, under or from any Property owned,
operated or leased by the Borrower or any of its Subsidiaries, or the failure by
the Borrower or any of its Subsidiaries to comply with any Environmental Law
(but excluding, in the case of either of clause (A) or (B) above, any such
losses, liabilities, claims, damages or expenses to the extent incurred by
reason of gross negligence or willful misconduct on the part of the Person to be
indemnified).

          -------------------------------- 

     Neither this Credit Agreement nor any other Credit Document nor any of the
terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing entered into by, or approved in writing by, the Required Lenders and the
Borrower, provided, however, that:
          --------  -------       

          (a) no such amendment, change, waiver, discharge or termination shall,
     without the consent of each Lender directly affected thereby, (i) reduce
     the rate or extend the time of payment of interest (other than as a result
     of waiving the applicability of any post-default increase in interest
     rates) on any Loan or the Commitment Fee or the Letter of Credit Fee
     hereunder, (ii) extend (A) the Commitments of the Lenders, or (B) the final
     maturity of any Loan, or (iii) reduce the principal amount on any Loan;

     Commitments of the Lenders over the amount thereof in effect (it being
     understood and agreed that a waiver of any Default or Event of Default or
     of a mandatory reduction in the total commitments shall not constitute a
     change in the terms of any Commitment of any Lender), (ii) except as the
     result of or in connection with a release of collateral as provided in
     Section 3.16 or with a dissolution, merger or disposition permitted under
     Section 8.4 of the Incorporated Covenants, release all or substantially all

     or 9.9, (iv) reduce any percentage specified in, or otherwise modify, the
     definition of "Required Lenders," or (v) consent to the assignment or
     transfer by the Borrower (or any Guarantor) of any of its rights and
     obligations under (or in respect of) the Credit Documents to which it is a

     (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND

provisions.

     9.12 Entirety.
          -------- 

     This Credit Agreement together with the other Credit Documents represent

the Closing Date when it shall have been executed by the Borrower, the
Guarantors and the Administrative Agent, and the Administrative Agent shall have
received copies hereof (telefaxed or otherwise) which, when taken together, bear

Administrative Agent and each Lender and their respective successors and
assigns.

     (b) The term of this Credit Agreement shall be until no Loans, or any other

          --------------- 

     The Administrative Agent and the Lenders agree to keep confidential (and to
cause their respective affiliates, officers, directors, employees,
Administrative Agents and representatives to keep confidential) all information,
materials and documents furnished to the Administrative Agent or any such Lender
by or on behalf of any Credit Party (whether before or after the Closing Date)
which relates to the Company, the Borrower or any of their Subsidiaries (the
                                                                            
"Information").  Notwithstanding the foregoing, the Administrative Agent and
- - ------------                                                                
each Lender shall be permitted to disclose Information (i) to its affiliates,
officers, directors, employees, Administrative Agents and representatives in
connection with its participation in any of the transactions evidenced by this
Credit Agreement or any other Credit Documents or the administration of this
Credit Agreement or any other Credit Documents; (ii) to the extent required by
applicable laws and regulations or by any subpoena or similar legal process, or
requested by any Governmental Authority; (iii) to the 

                                       42
<PAGE>
 
extent such Information (A) becomes publicly available other than as a result of
a breach of this Credit Agreement or any agreement entered into pursuant to
clause (iv) below, (B) becomes available to the Administrative Agent or such
Lender on a non-confidential basis from a source other than a Credit Party or
(C) was available to the Administrative Agent or such Lender on a non-
confidential basis prior to its disclosure to the Administrative Agent or such
Lender by a Credit Party; (iv) to any assignee or participant (or prospective
assignee or participant) so long as such assignee or participant (or prospective
assignee or participant) first specifically agrees in a writing furnished to and
for the benefit of the Credit Parties to be bound by the terms of this Section
9.14; or (v) to the extent that the Borrower shall have consented in writing to
such disclosure. Nothing set forth in this Section 9.14 shall obligate the
Administrative Agent or any Lender to return any materials furnished by the
Credit Parties.

     9.15 Source of Funds.
          --------------- 

     Each of the Lenders hereby represents and warrants to the Borrower that at
least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder:

          (a) no part of such funds constitutes assets allocated to any separate
     account maintained by such Lender in which any employee benefit plan (or
     its related trust) has any interest;

          (b) to the extent that any part of such funds constitutes assets
     allocated to any separate account maintained by such Lender, such Lender
     has disclosed to the Borrower the name of each employee benefit plan whose
     assets in such account exceed 10% of the total assets of such account as of
     the date of such purchase (and, for purposes of this subsection (b), all
     employee benefit plans maintained by the same employer or employee
     organization are deemed to be a single plan);

          (c) to the extent that any part of such funds constitutes assets of an
     insurance company's general account, such insurance company has complied
     with all of the requirements of the regulations issued under Section
     401(c)(1)(A) of ERISA; or

          (d) such funds constitute assets of one or more specific benefit plans
     which such Lender has identified in writing to the Borrower.

As used in this Section 9.15, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

     9.16 Conflict.
          -------- 

     To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Credit Agreement shall control.
