                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. The accounting policies followed by the Company are set forth in Note 1 of
   Notes to Consolidated Financial Statements included in the Company's Annual
   Report on Form 10-K for the year ended June 28, 1997.
 
2. Effective December 27, 1997, the Company adopted Statement of Financial
   Accounting Standards No. 128, "Earnings per Share" (SFAS No. 128). This
   statement replaces the previously reported primary and fully diluted earnings
   (loss) per share with basic and diluted earnings (loss) per share. Unlike
   primary earnings (loss) per share, basic earnings (loss) per share excludes
   any diluted effects of options. Diluted earnings (loss) per share is very
   similar to the previously reported fully diluted earnings (loss) per share.
   All earnings (loss) per share amounts have been restated to conform to the
   SFAS No. 128 requirements.
 
   The following table illustrates the computation of basic and diluted earnings
   (loss) per share:

   The computation of diluted loss per share for the three-month and six-month
   periods ended December 27, 1997 excluded the effect of incremental common
   shares attributable to the exercise of outstanding common stock options, put
   options and ESPP contributions because their effect was antidilutive.
   Substantially all options to purchase shares of common stock were included in
   the computation of diluted earnings per share for the three-month and
   six-month periods ended December 28, 1996.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
4. During the six months ended December 27, 1997, approximately 786,000 and
   702,000 shares of common stock were distributed in connection with the
   Employee Stock Purchase Plan ("ESPP") and common stock option exercises,
   respectively, for $13.5 million.
 
5. In the opinion of management, all adjustments necessary to fairly state the
   consolidated financial statements have been made. All such adjustments are of
   a normal recurring nature. Certain information and footnote disclosures
   normally included in the financial statements prepared in accordance with
   generally accepted accounting principles have been condensed or omitted
   pursuant to the rules and regulations of the Securities and Exchange
   Commission. These consolidated financial statements should be read in
   conjunction with the consolidated financial statements and the notes thereto
   included in the Company's Annual Report on Form 10-K for the year ended June
   28, 1997.
 
6. On January 28, 1998, the Company replaced its then existing revolving credit
   facility with a secured revolving credit and term loan facility ("Senior Bank
   Facility"). The Senior Bank Facility provides the Company with a $200 million
   revolving credit line and a $50 million term loan, both of which expire in
   January 2001. The Senior Bank Facility is secured by the Company's accounts
   receivable, inventory, 66% of its stock in its foreign subsidiaries and the
   other assets (excluding real property) of the Company. At the option of the
   Company, borrowings bear interest at either Libor plus a margin determined by
   a total debt funded ratio or a base rate, with option periods of one to six
   months. The Senior Bank Facility requires the Company to maintain certain
   financial ratios, restricts the payment of dividends and contains a number of
   other restrictive covenants. As of February 5, 1998, the $50 million term
   loan was funded but there were no borrowings under the revolving credit line.
 
7. Since early December 1997, a number of securities class action lawsuits have
   been filed against the Company and certain of its officers and directors in
   United States District Court for the Central District of California. The
   plaintiffs in these actions are persons who purchased shares of the Company's
   common stock on the open market during calendar 1996 and 1997, and who are
   asserting claims for monetary damages in an unspecified amount on behalf of
   themselves and other similarly situated purchasers of the Company's common
   stock. These actions followed the Company's announcement on December 2, 1997
   of its plans to reduce production, accelerate its transition to MR head
   technology, exit the 3-inch drive business, and take associated accounting
   charges. The complaints allege essentially that during calendar 1996 and 1997
   and before the December 2, 1997 announcement, the Company and its officers
   knew the Company was experiencing and would continue to experience
   difficulties with its transition from thin film to MR head technology which
   would subject the Company to, among other things, low-end pricing pressures
   and the risk of obsolete inventory. The complaints further allege that
   nonetheless the Company made false and misleading statements concerning the
   outlook for the Company's operations and earnings and issued financial
   statements that were false and misleading in various ways, including improper
   deferral of obsolete inventory write-downs. The complaints further assert
   that the Company's officers made the alleged misleading statements in order
   to keep the market price of the Company's stock at artificially high levels
   for various reasons, including to facilitate the sale of their own shares and
   to deter potential acquirors. The Company believes that additional suits may
   be filed containing similar allegations. The Company's directors and officers
   liability insurance carriers have been notified of the claims that have been
   received. Although the Company has had only a limited time to review these
   complaints, it believes that it has meritorious defenses to the claims and
   intends to defend itself vigorously. However, such litigation could result in
   substantial costs and a diversion of resources and management's attention.
 
8. During the third and fourth quarters of fiscal 1998, the Company is obligated
   to settle certain put option arrangements entered into in connection with its
   open market stock repurchase program. Under this program, the Company, since
   February 1995, has spent approximately $300 million in connection with the
   repurchase of approximately 22.2 million shares of its common stock at an
   average price of $13.50 per share. The Company has the option to settle these
   obligations in cash or by issuing additional common

   stock, which would have a dilutive effect upon existing shareholders. The
   amount of the settlements will be based upon the value of the Company's
   common stock at the time of settlement, and the decision whether to make
   these settlements in cash or stock, or a combination of both, will be made
   based upon prevailing market conditions and other factors at the time of
   settlement. At the market price for the Company's common stock on February 3,
   1998, the total cash payment, if elected, would have been approximately $20.7
   million. Pending settlement, approximately $26.4 million of the Company's
   cash was restricted at December 27, 1997 to secure the Company's obligations
   under these arrangements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
RECENT DEVELOPMENTS
 
     Competitive market conditions in the hard drive industry, including
unusually severe pricing pressure, sustained oversupply, and increasing
availability of MR head products from competitors, prompted the Company in the
second quarter of fiscal 1998 to initiate a series of actions designed to reduce
its exposure to these competitive conditions and to sharpen the Company's focus
and resources on its desktop and enterprise storage product lines. These actions
included a reduction in the planned production of desktop hard drives, an
acceleration of the transition from thin film recording head technology to MR
head technology, and termination of the Company's 3-inch hard drive product line
targeted at the mobile PC marketplace. Primarily as a result of these actions,
the Company recorded $148 million of special charges in the second quarter of
fiscal 1998. The special charges include estimated component cancellation
charges, inventory and other asset write-downs, costs incurred during the
quarter on terminated mobile PC engineering programs, and other estimated
incremental costs related to the production, sale, and accelerated wind-down of
thin film and ramp-up of MR products. Of this amount, approximately $40 million
consists of non-cash items, approximately $35 million utilized cash in the
second quarter of fiscal 1998, and the majority of the balance will require cash
expenditures during the third and fourth quarters of fiscal 1998. The special
charges are based upon a number of estimates and assumptions, and although these
estimates and assumptions were based upon the best information available to the
Company at the time, the actual costs incurred by the Company in connection with
these actions may exceed the charges recorded.

     Consolidated revenues were $970 million in the second quarter of 1998, a
decrease of 13% and 11% from the second quarter of the prior year and the
immediately preceding quarter, respectively. Consolidated revenues were $2.1
billion in the first six months of 1998, up 3% from the corresponding period of
1997. The decline in revenues in the current quarter stemmed from 5% and 8%
reductions in hard drive unit shipments as compared to the corresponding quarter
of the prior year and the immediately preceding quarter, respectively. The
increase in revenues in the first six months of 1998 over the corresponding
period of the prior year resulted from an overall 10% increase in hard drive
unit shipments. An intensely competitive hard drive business environment,
particularly during the second quarter of 1998, resulted in reductions in the
average selling prices of hard drive products which in turn affected
consolidated revenues during the three and six-month periods ended December 27,
1997.
 
     The reduction in gross profit margin from the immediately preceding quarter
and the corresponding period of 1997 was primarily related to three factors.
First, $148 million of special charges were recorded in the second quarter of
1998, primarily to cost of sales. See "Recent Developments." Second, unusually
severe competitive pricing pressures were experienced in the desktop storage
market during the second quarter of 1998. Finally, the Company experienced
higher manufacturing costs associated with extending the life of thin film head
technology in desktop storage products. Partially offsetting this reduction in
gross profit margin were incremental sales of the Company's enterprise storage
products, which have higher average gross profit margins than the Company's
desktop storage products.
 
     Research and development ("R&D") expense for the current quarter was $44.5
million, an increase of $8.5 million and $2.2 million over the second quarter of
the prior year and the immediately preceding quarter, respectively. R&D expense
for the first six months of 1998 was $86.8 million, an increase of $16.5 million
over the corresponding period of the prior year. The increases in absolute
dollars spent over the corresponding periods of the prior year and the
immediately preceding quarter are primarily associated with higher expenditures
to support the development of desktop hard drives. The increases in R&D expense
as a percentage of revenues in the current quarter over the second quarter of
1997 and the immediately preceding quarter are primarily the result of the lower
revenue base.
 
     Selling, general and administrative ("SG&A") expense for the second quarter
of 1998 was $47.2 million, a decrease of $8.4 million from the corresponding
quarter of 1997. SG&A expense for the first six months of 1998 was $93.8
million, a decrease of $4.6 million from the corresponding period of the prior
year. The decrease from the second quarter and the first six months of 1997 is
primarily the result of lower expenses for the Company's pay-for-performance and
profit sharing plans.

     Net interest and other income for the current quarter was $2.0 million, a
decrease of $1.7 million and $.6 million from the second quarter of the prior
year and the immediately preceding quarter, respectively. Interest and other
income for the first six months of 1998 was $4.6 million, a decrease of $2.0
million from the corresponding period of the prior year. The decreases are
primarily the result of lower average cash and cash equivalent balances in the
current periods as compared to corresponding periods of the prior year and the
immediately preceding quarter.
 
     The Company's effective tax rate for the three and six-month periods ended
December 28, 1996 results primarily from the earnings of certain subsidiaries
which are taxed at substantially lower tax rates as compared with United States
statutory rates and changes in the deferred tax asset valuation allowance. The
provision for income taxes recorded in the first half of 1998 results primarily
from positive earnings at certain of the Company's international subsidiaries.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At December 27, 1997, the Company had $119.3 million in cash and cash
equivalents as compared to $208.3 million at June 28, 1997. Net cash provided by
operating activities was $14.0 million for the six-month period ended December
27, 1997, compared to $159.6 million for the six-month period ended December 28,
1996. Cash flows from depreciation and amortization, lower accounts receivable
balances, and an increase in total operating liabilities were partially offset
by cash used to fund higher inventory balances and the net loss. Another
significant use of cash during the first six months of 1998 was capital
expenditures of $111.8 million, which were incurred primarily in connection with
the transition to desktop and enterprise hard drives featuring MR head
technology and increased capacity to support future production of hard drives
and related components.
 
     The Company's previously existing $150 million revolving credit line, which
had an outstanding balance of $24 million drawn on December 29, 1997, was repaid
and terminated on January 28, 1998. To replace this $150 million facility, the
Company entered into a credit facility ("Senior Bank Facility") on January 28,
1998, pursuant to which BankBoston, N.A. and other lending institutions are
providing a $200 million revolving credit line and a $50 million term loan, both
of which expire in January 2001. The Senior Bank Facility is secured by the
Company's accounts receivable, inventory, 66% of its stock in its foreign
subsidiaries and the other assets (excluding real property) of the Company. At
the option of the Company, borrowings bear interest at either LIBOR plus a
margin determined by a total debt funded ratio or a base rate, with option
periods of one to six months. The Senior Bank Facility requires the Company to
maintain certain financial ratios, restricts the payment of dividends and
contains a number of other restrictive covenants. As of the date hereof, the $50
million term loan was funded but there were no borrowings under the revolving
credit line. The Senior Bank Facility is intended to meet short-term working
capital requirements which may arise from time to time.
 
     On December 29, 1997, the Company purchased approximately 34 acres of land
in Irvine, California for approximately $22 million. The Company is exploring
various financing alternatives for construction of a new corporate headquarters
on this site. The new headquarters facility is not expected to materially
increase the Company's occupancy costs. However, there can be no assurance that
the Company will be successful in entering into a financing arrangement for this
property on terms that will be satisfactory to the Company and
 
                                       12
<PAGE>   13
 
other alternatives available to the Company upon expiration of its current
headquarters lease could be more costly.
 
     During the third and fourth quarters of 1998, the Company is obligated to
settle certain put option arrangements entered into in connection with its open
market stock repurchase program. Under this program, the Company, since February
1995, has spent approximately $300 million in connection with the repurchase of
approximately 22.2 million shares of its common stock at an average price of
$13.50 per share. The Company has the option to settle these obligations in cash
or by issuing additional common stock, which would have a dilutive effect upon
existing shareholders. The amount of the settlements will be based upon the
value of the Company's common stock at the time of settlement, and the decision
whether to make these settlements in cash or stock, or a combination of both,
will be made based upon prevailing market conditions and other factors at the
time of settlement. At the market price for the Company's common stock on
February 3, 1998, the total cash payment, if elected, would have been
approximately $20.7 million. Pending settlement, approximately $26.4 million of
the Company's cash was restricted at December 27, 1997 to secure the Company's
obligations under these arrangements.
 
     The Company believes that its current cash balances combined with cash flow
from operations and the Senior Bank Facility will be sufficient to meet its
working capital needs for the foreseeable future. However, the Company's ability
to sustain its working capital position is dependent upon a number of factors
that are discussed below under the heading "Certain Factors Affecting Western
Digital Corporation and/or the Hard Drive Industry."
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     Effective December 28, 1997, the Company adopted Statement of Financial
Accounting Standards No. 128, "Earnings per Share" (SFAS No. 128). This
statement replaces the previously reported primary and fully diluted earnings
(loss) per share with basic and diluted earnings (loss) per share. Unlike
primary earnings (loss) per share, basic earnings (loss) per share excludes any
dilutive effects of options and convertible securities. Diluted earnings (loss)
per share is very similar to the previously reported fully diluted earnings
(loss) per share. All earnings (loss) per share amounts for all periods have
been restated to conform to the SFAS No. 128 requirements.
 
YEAR 2000
 
     Many existing software programs use only two digits to identify the year in
the date field. If such programs are not corrected, date data concerning the
Year 2000 could cause many computer applications to fail, lock-up or generate
erroneous results. As storage devices, the Company's hard drives are transparent
to Year 2000 requirements and can be deemed Year 2000 compliant when used in
accordance with Company product documentation and provided that all hardware,
firmware, middleware and software used in combination with the hard drive
exchange accurate data therewith.
 
     The Company has committed personnel and resources to resolve potential Year
2000 issues, both internally and externally (with respect to the Company's
suppliers and customers). The Company is in the process of identifying and
assessing its mission-critical systems related to the Year 2000. Although the
Company plans to address Year 2000 issues with respect to the Company's
mission-critical internal systems in sufficient time prior to the century
rollover, there can be no assurance that there will not be interruption of
operations or other limitations of system functionality, or that the Company
will not incur substantial costs to avoid such occurrences.
 
     The Company is currently assessing the cost to remediate its Year 2000
issues. Although the actual cost to remediate these issues is not yet fully
known, based upon information to date, it is not expected that the remediation
will have a material impact on the Company's financial condition or operating
results.

CERTAIN FACTORS AFFECTING WESTERN DIGITAL CORPORATION AND/OR THE DISK DRIVE
INDUSTRY
 
     Highly Competitive Industry. The desktop portion of the hard drive industry
consists of many competitors of various sizes and financial resources. Although
price competition and price erosion were not as severe in 1997 as in some
previous years, the desktop hard drive industry is currently experiencing a
period of sustained oversupply and unusually severe pricing pressures which have
resulted in price competition and price erosion that the Company expects to
continue for the foreseeable future.
 
     During 1996 and 1997, the Company significantly increased its market share
in the desktop hard drive market, but some of these market share gains eroded in
the second quarter of 1998, primarily due to competitive conditions in the disk
drive industry (with resulting cut backs in production) and the timing of the
Company's transition from thin film to magneto-resistive ("MR") head technology.
There can be no assurance that the Company will be able to recover recent market
share losses or increase its market share beyond historical levels. Maxtor and
Fujitsu have joined Seagate, Quantum and IBM as major competitors in the data
storage business, and Fujitsu has already gained significant market share in the
desktop market as a result of its aggressive pricing strategy and competitive
products. Maxtor has also recently gained market share due to several factors,
including improved product offerings. The current intense competitive conditions
in this market make it difficult to forecast near-term operating results. This
competitive environment has adversely affected the Company's operating results
for the first half of 1998, and the Company expects these conditions to continue
for at least the remainder of 1998. See "Recent Developments."
 
     The enterprise portion of the hard drive market is more concentrated than
the desktop portion, with the largest competitor, Seagate, having a market share
in excess of 50% in recent years. The Company entered this market in 1997 and
competes with Seagate, Quantum, IBM and Fujitsu. Because the number of
competitors in this market has increased, the Company expects that price
competition in the enterprise market will increase. The Company's continued
success in the enterprise hard drive market is heavily dependent on the
successful development, timely introduction and market acceptance of new
products, and failure to achieve such success could adversely affect the
Company's financial condition or operating results.
 
     In general, the unit price for a given product in both the desktop and
enterprise markets decreases over time as increases in industry supply and cost
reductions occur and as technological advancements are achieved. Cost reductions
result primarily from volume efficiencies, component cost reductions,
manufacturing experience and design enhancements that are generally realized
over the life of a product. Competitive pressures and customer expectations
compel manufacturers to pass these cost reductions along as reductions in
selling prices. The rate of general price decline accelerates when some
competitors lower prices to absorb excess capacity, liquidate excess inventories
or attempt to gain market share. Competition and continuing price erosion could
adversely affect the Company's financial condition or operating results in any
given quarter. Often, such adverse effects cannot be anticipated until late in
the quarter, as has happened during the first two quarters of 1998.
 
     Rapid Technological Change and Product Development. The demands of hard
drive customers for greater storage capacity and higher performance have led to
short product life cycles, which require the Company to constantly develop and
introduce new drive products on a cost-effective and timely basis. The Company's
expenditure of research and development funds to support rapid technological
change depends upon its revenues and profitability, and reductions in such
expenditures could impair the Company's ability to innovate and compete.
 
     The Company experiences fluctuations in manufacturing yields that can
materially affect the Company's operations, particularly in the start-up phase
of new products or new manufacturing processes, and also at the end of a
technology's life cycle, when refinements designed to reach the product's
technical limits can result in tighter manufacturing tolerances. With the
continued pressures to shorten the time required to introduce new products, the
Company must accelerate production learning curves to shorten the time to
achieve acceptable manufacturing yields and costs. The Company's future is
therefore dependent upon its ability to develop new products, qualify these new
products with its customers, successfully introduce these products to the market
 
                                       14
<PAGE>   15
 
on a timely basis and commence volume production to meet customer demands. If
not carefully planned and executed, the transition to new products may adversely
affect sales of existing products and increase risk of inventory obsolescence. A
delay in the introduction or production of more cost-effective and/or more
advanced products also can result in lower sales and lower gross margins.
Because of rapid technological changes, the Company anticipates that sales of
older products will decline as in the past and that sales of new products will
continue to account for a significant portion of its sales in the future.
Failure of the Company to execute its strategy of achieving time-to-market in
sufficient volume with new products, or any delay in the introduction of
advanced and cost-effective products, could result in significantly lower
revenue and gross margins. Some of these factors have adversely affected the
Company in connection with the maturation of and transition from thin film
recording head technology. For a discussion of this transition from thin film
recording head technology to MR head technology and associated special charges
in the second quarter of 1998, see "Recent Developments."
 
     Advances in magnetic, optical or other technologies, or the development of
entirely new technologies, could result in the creation of competitive products
that have better performance and/or lower prices than the Company's products.
For example, the next generation of head technology, known as "Giant MR," has
already been introduced on a limited basis by IBM. Additionally, companies such
as TeraStor and Seagate are currently developing optically-assisted recording
technologies. The initial products from such companies are expected to be high
capacity and high price, although cost-effective per gigabyte. The
optically-assisted recording approaches used by these two companies are
different at this time and have created some short-term confusion in the
industry. Accordingly, the Company's strategy is to view optically-assisted
recording as a potentially valid solution at some point in time, but to assume
that the hard drive technologies currently in use will serve the Company for the
foreseeable future. However, if the Company's assumption proves to be wrong, the
Company could be late in its integration of optically-assisted recording
technology, which could have an adverse effect on the Company's financial
condition or operating results.
 
     Development and Production of Drives with MR Recording Heads. The majority
of the Company's hard drive products currently utilize conventional thin film or
metal-in-gap ("MIG") inductive head technologies. MR heads, which enable higher
capacity per hard drive than conventional thin film or MIG inductive heads, have
replaced thin film and MIG inductive heads as the leading recording head
technology. Several of the Company's major competitors are substantially ahead
of the Company in incorporating MR head technology into some of their current
products and, with higher capacity drives using MR heads, some of the Company's
competitors achieved time-to-market leadership with certain MR products. In
September 1997, the Company commenced volume production of its first desktop
drive product incorporating MR head technology, a 2.1 GB per platter drive, and
with that introduction, the Company regained time-to-market leadership at that
capacity point. Additionally, the Company commenced volume production in
December 1997 of the new low-profile 9.1 GB enterprise drive incorporating MR
head technology. The Company and IBM are currently the industry's sole suppliers
of low-profile 9.1 GB enterprise drives. As with most new products, the Company
anticipates that the new MR-based products may have lower initial manufacturing
yields and higher initial component costs than some more mature products. The
Company's ramp to volume production of MR head products has been successful to
date. However, the Company plans to have MR heads in 40% of products shipped by
the end of the third quarter of 1998, and in excess of 80% of products shipped
by the end of the fourth quarter of 1998. This plan depends upon continued
success in MR head technology throughout the full production process and no
assurance can be given that these goals will be achieved. Failure of the Company
to successfully execute the transition to MR head technology in a timely manner
and/or in sufficient volume during 1998 could cause further erosion of the
Company's market share and have an adverse effect on the Company's financial
condition or operating results.
 
     Fluctuating Product Demand. Demand for the Company's hard drive products
depends on the demand for the computer systems manufactured by its customers and
on storage upgrades to computer systems, which in turn are affected by computer
system product cycles, end user demand for increased storage capacity and
prevailing economic conditions. Although market research indicates total
computer system unit shipments are expected to continue to grow for the next
several years, demand may fluctuate significantly from period to period. Such
fluctuations have in the past and may in the future result in deferral or
cancellation of orders for
 
                                       15
<PAGE>   16
 
the Company's products, which could have an adverse effect on the Company's
financial condition or operating results.
 
     The hard drive industry has also experienced seasonal fluctuations in
demand. The Company has historically experienced relatively flat demand in the
first quarter of the fiscal year as compared to the fourth quarter, while demand
in the second quarter has historically been much higher than in the first
quarter. Additionally, product shipments tend to be greatest in the third month
of each quarter. The inability of the Company to accurately match its product
build plans to customer demand for any particular period could adversely affect
the Company's operating results for that period.
 
     Customer Concentration and Changing Customer Models. High volume customers
for hard drives are concentrated among a small number of OEMs, distributors and
retailers. Although the Company believes its relationships with key customers
such as these are generally very good, the concentration of sales to a
relatively small number of major customers represents a business risk that loss
of one or more accounts could adversely affect the Company's financial condition
or operating results. During each of 1995 and 1996, sales to Gateway 2000
accounted for 11% of revenues. During 1997, sales to IBM accounted for 13% of
revenues. For the six months ended December 27, 1997, sales to Compaq and IBM
accounted for 14% and 12% of revenues, respectively. The Company's customers are
generally not obligated to purchase any minimum volume and are generally able to
terminate their relationship with the Company at will. If any such change in
purchase volume or customer relationships resulted in decreased demand for the
Company's drives, whether by loss of or delays in orders, the Company's
financial condition or operating results could be adversely affected.
 
     The hard drive industry is experiencing changes in its OEM customer
ordering models. The trend among computer manufacturers using the
"build-to-order" model is to utilize a "just-in-time" ("JIT") inventory
management requirements model. As a result, Western Digital's customers are
holding smaller inventories of components such as hard drives. This JIT ordering
requires the Company to maintain a certain base stock of product in a location
adjacent to its customers' manufacturing facilities. JIT ordering complicates
the Company's inventory management strategies and makes it more difficult to
match manufacturing plans with projected customer demand. The Company's failure
to manage its inventory in response to JIT demands could have an adverse effect
on its operating results.
 
     Large OEMs are also considering or have implemented a "channel assembly"
model in which the OEM ships a minimal computer system to the dealer or other
assembler, and component suppliers such as hard drive manufacturers are
requested to ship parts directly to the assembler for installation at its
location. With this model, fragmentation of manufacturing facilities exposes the
Company to some risk of inventory mismanagement by both the OEMs and the
assemblers. The shift requires effective inventory management by the Company,
and any increase in the number of "ship to locations" may increase freight costs
and the number of accounts to be managed. Additionally, if the assemblers are
not properly trained in manufacturing processes, it could also increase the
number of product returns resulting from damage during assembly or improper
installation. This model requires proper alignment between the OEM and the
Company and requires the Company to retain more of its product in inventory. The
Company is therefore exposed to increased risk of inventory obsolescence with
the channel assembly model as well as the JIT model. The Company's OEM customer
relationships have traditionally been strong, but a material adverse change in
an OEM relationship could adversely affect demand for the Company's products,
especially with the impact of these new models.
 
     Dependence on Suppliers of Components. The Company is dependent on
qualified suppliers for components, including recording heads, head stack
assemblies, media and integrated circuits. A number of the components used by
the Company are available from a single or limited number of outside suppliers.
Some of these materials may periodically be in short supply, and the Company
has, on occasion, experienced temporary delays or increased costs in obtaining
these materials. As a result, the Company must allow for significant lead times
when procuring certain materials and supplies. In addition, cancellation of
orders for components due to cut-backs in production precipitated by market
oversupply or transition to new products or technologies can result in payment
of significant cancellation charges to suppliers. See "Recent Developments."
Because the Company is less vertically integrated than its competitors, an
extended shortage of required materials and supplies or the failure of key
suppliers to meet the Company's quality, yield or production requirements could
affect the Company more severely than competitors.
 
                                       16

     Intellectual Property. The hard drive industry has been characterized by
significant litigation relating to patent and other intellectual property
rights. From time to time, the Company receives claims of alleged patent
infringement or notice of patents from patent holders, which typically contain
an offer to grant the Company a license. On June 10, 1994, Papst Licensing
("Papst") brought suit against the Company in the United States District Court
for the Central District of California alleging infringement by the Company of
five hard drive motor patents owned by Papst. The patents relate to disk drive
motors that the Company purchases from motor vendors. On December 1, 1994, Papst
dismissed its case without prejudice, but has recently notified the Company that
it intends to reinstate the suit if the Company does not agree to enter into a
license agreement with Papst. Papst has also put the Company on notice with
respect to several additional patents. Although the Company does not believe
that the outcome of this matter will have an adverse effect on its financial
condition or operating results, adverse resolution of any intellectual property
litigation could subject the Company to substantial liabilities and require it
to refrain from manufacturing certain products. In addition, the costs of
defending such litigation may be substantial, regardless of the outcome.
 
     The Company's success depends in significant part on the proprietary nature
of its technology. Patents issued to the Company may not provide the Company
with meaningful advantages and may be challenged. In addition to patent
protection of certain intellectual property rights, the Company considers
elements of its product designs and processes to be proprietary and
confidential. The Company believes that its non-patentable intellectual
property, particularly some of its process technology, is an important factor in
its success. The Company relies upon employee, consultant, and vendor
non-disclosure agreements and a system of internal safeguards to protect its
proprietary information. Despite these safeguards, to the extent that a
competitor of the Company is able to reproduce or otherwise capitalize on the
Company's technology, it may be difficult or impossible for the Company to
obtain necessary intellectual property protection in the United States or other
countries where such competitor conducts its operations. Moreover, the laws of
foreign countries may not protect the Company's intellectual property to the
same extent as do the laws of the United States.
 
     Legal Proceedings. The Company was sued by Amstrad plc ("Amstrad") in
December 1992 in Orange County Superior Court. The complaint alleges that hard
drives supplied by the Company in calendar 1988 and 1989 were defective and
caused damages to Amstrad of $186.0 million in out-of-pocket expenses, lost
profits, injury to Amstrad's reputation and loss of goodwill. The Company filed
a counterclaim for $3.0 million in actual damages in addition to exemplary
damages in an unspecified amount. The Company believes that it has meritorious
defenses to Amstrad's claims and intends to vigorously defend itself against the
Amstrad claims and to press its claims against Amstrad in this action. Although
the Company believes that the final disposition of this matter will not have an
adverse effect on the Company's financial condition or operating results, if
Amstrad were to prevail on its claims, a judgment for a material amount could be
awarded against the Company.
 
     Since early December 1997, a number of securities class action lawsuits
have been filed against the Company and certain of its officers and directors in
United States District Court for the Central District of California. The
plaintiffs in these actions are persons who purchased shares of the Company's
common stock on the open market during calendar 1996 and 1997, and who are
asserting claims for monetary damages in an unspecified amount on behalf of
themselves and other similarly situated purchasers of the Company's common
stock. These actions followed the Company's announcement on December 2, 1997 of
its plans to reduce production, accelerate its transition to MR head technology,
exit the 3-inch drive business, and take associated accounting charges. The
complaints allege essentially that during calendar 1996 and 1997 and before the
December 2, 1997 announcement, the Company and its officers knew that the
Company was experiencing and would continue to experience difficulties with its
transition from thin film to MR head technology which would subject the Company
to, among other things, low-end pricing pressures and the risk of obsolete
inventory. The complaints further allege that nonetheless the Company made false
and misleading statements concerning the outlook for the Company's operations
and earnings and issued financial statements that were false and misleading in
various ways, including improper deferral of obsolete inventory write-downs. The
complaints further assert that the Company's officers made the alleged
misleading statements in order to keep the market price of the Company's stock
at artificially high levels for various reasons, including to facilitate the
sale of their own shares and to deter potential acquirors. The Company believes
that additional
 
                                       17
<PAGE>   18
 
suits may be filed containing similar allegations. The Company's directors and
officers liability insurance carriers have been notified of the claims that have
been received. Although the Company has had only a limited time to review these
complaints, it believes that it has meritorious defenses to the claims and
intends to defend itself vigorously. However, such litigation could result in
substantial costs and a diversion of resources and management's attention.
 
     The Company is also subject to other legal proceedings and claims which
arise in the ordinary course of business. Although occasional adverse decisions
or settlements may occur, the Company believes that the final disposition of
such matters will not have an adverse effect on its financial condition or
operating results.
 
     Use of Estimates. The Company's management has made a number of estimates
and assumptions relating to the reporting of assets and liabilities. Such
estimates include, but are not limited to, accruals for warranty against product
defects, price protection and stock rotation reserves on product sold to
resellers, and reserves for excess, obsolete and slow moving inventories. The
rapidly changing market conditions in the hard drive industry make it difficult
to estimate such accruals and reserves and actual results may differ
significantly from the Company's estimates and assumptions, including those used
in determining the special charges in the second quarter of 1998 described in
"Recent Developments." Differences between actual results and such estimates and
assumptions can result in adverse effects on the Company's financial condition
or operating results.
 
     Potential Impact of Changing Market Demands. The information services
business community is currently debating the "thin client architecture" or
network computer ("NC") model, which emphasizes central servers for data storage
and reduces the need for local desktop storage. Although industry analysts
expect these products to account for a small fraction of the personal computer
market over the next several years, broader than expected adoption of the NC
model would reduce demand for desktop storage products while increasing demand
for enterprise storage products. Given the Company's current business
concentration in desktop disk drives and its relatively recent entry into
enterprise disk drives, if such a scenario occurred on an accelerated basis, it
would place the Company at a disadvantage relative to competitors which have a
stronger market position in enterprise products.
 
     In addition, certain of the large desktop PC system manufacturers have
recently introduced lower cost, lower performance systems principally for the
consumer marketplace. These systems have generally been priced below $1,000 per
system and typically contain hard drives with lower capacity. The Company
currently participates in this market only to a limited extent, and if this
market continues to grow rapidly, the Company will need to develop appropriate
lower-cost disk drive products for these systems to avoid losing market share.
 
     Foreign Manufacturing Risks. Western Digital products are currently
manufactured in Singapore and Malaysia. The Company is subject to certain risks
associated with foreign manufacturing, including obtaining requisite United
States and foreign governmental permits and approvals, currency exchange
fluctuations, currency restrictions, political instability, transportation
delays, labor problems, trade restrictions, import, export, exchange and tax
controls and reallocations, loss or non-renewal of favorable tax treatment under
agreements with foreign tax authorities and changes in tariff and freight rates.
 
     Possible Price Volatility of Common Stock. The market price of the
Company's common stock has been, and may continue to be, extremely volatile and
may be significantly affected by factors such as actual or anticipated
fluctuations in the Company's operating results, announcements of technological
innovations, new products introduced by the Company or its competitors, periods
of severe pricing pressures, developments with respect to patents or proprietary
rights, conditions and trends in the hard drive industry, changes in financial
estimates by securities analysts, general market conditions and other factors.
In addition, the stock market has experienced extreme price and volume
fluctuations that have particularly affected the market price for many high
technology companies that have often been unrelated to the operating performance
of these companies. These broad market fluctuations may adversely affect the
market price of the Company's common stock, and there can be no assurance that
the market price of the common stock will not decline. Securities class action
litigation suits are often brought against companies following periods of
volatility in the market price of their securities, and a number of such suits
have been filed against the Company since early December 1997. See
 
                                       18
<PAGE>   19
 
"Legal Proceedings." Any such litigation against the Company could result in
substantial costs and a diversion of resources and management's attention.
 
     Future Capital Needs. The hard drive industry is capital intensive, and in
order to remain competitive, the Company will need to maintain adequate
financial resources for capital expenditures, working capital and research and
development. If the Company decides to increase its capital expenditures
further, or sooner than presently contemplated, or if results of operations do
not meet the Company's expectations, the Company could require additional debt
or equity financing, and such equity financing could be dilutive to the
Company's existing shareholders. There can be no assurance that such additional
funds will be available to the Company or available on favorable terms. The
Company may also require additional capital for other purposes not presently
contemplated. If the Company is unable to obtain sufficient capital, it could be
required to curtail its capital equipment and research and development
expenditures, which could adversely affect the Company's financial condition or
operating results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."
 
     Foreign Exchange Contracts. The Company manages the impact of foreign
currency exchange rate changes on certain underlying assets, liabilities and
anticipated cash flows for operating expenses denominated in foreign currencies
by entering into short-term, forward exchange contracts. With this approach, the
Company expects to minimize the impact of changing foreign exchange rates on the
Company's operations. However, there can be no assurance that all foreign
currency exposures will be adequately covered, and that the Company's financial
condition or operating results will not be affected by changing foreign exchange
rates.
 
     Year 2000 Issue. Many existing software programs use only two digits to
identify the year in the date field. If such programs are not corrected, date
data concerning the Year 2000 could cause many computer applications to fail,
lock-up or generate erroneous results. Virtually all companies will be affected
by the Year 2000 issue. As storage devices, the Company's hard drives are
transparent to Year 2000 requirements and can be deemed Year 2000 compliant when
used in accordance with Company product documentation and provided that all
hardware, firmware, middleware and software used in combination with the hard
drive exchange accurate data therewith.
 
     The Company has committed personnel and resources to resolve potential Year
2000 issues, both internally and externally (with respect to the Company's
suppliers and customers). The Company is in the process of identifying and
assessing its mission-critical systems related to the Year 2000. Although the
Company plans to address Year 2000 issues with respect to the Company's
mission-critical internal systems in sufficient time prior to the century
rollover, there can be no assurance that there will not be interruption of
operations or other limitations of system functionality, or that the Company
will not incur substantial costs to avoid such occurrences. Any failure to
effectively monitor, implement or improve the Company's internal and external
operational, financial, management and technical support systems could have a
material adverse effect on the Company's financial condition or operating
results.

PART II. OTHER INFORMATION
 
ITEM 1. LEGAL PROCEEDINGS
 
     On May 9, 1997, the Bay Area Air Quality Management District ("District")
filed suit against the Company in Santa Clara Superior Court. The complaint
alleged that isopropyl alcohol dryers at the Company's Santa Clara Media
facility do not comply with the District's emission control requirements and the
conditions of the permit issued by the District to the Company for the dryers
and sought damages of $300,000. The Company entered into a Settlement Agreement
with the District pursuant to which the District will dismiss the suit with
prejudice.

                           WESTERN DIGITAL CORPORATION
                              AMENDED AND RESTATED
                           EMPLOYEE STOCK OPTION PLAN


        1. Purpose. The purpose of this Western Digital Corporation Employee
Stock Option Plan (the "Plan") is to further the growth and development of
Western Digital Corporation (the "Company") and its subsidiaries by providing,
through ownership of stock of the Company, an incentive to officers and other
key employees who are in a position to contribute materially to the prosperity
of the Company, to increase such persons' interest in the Company's welfare, to
encourage them to continue their services to the Company or its subsidiaries,
and to attract individuals of outstanding ability to enter the employment of the
Company or its subsidiaries.

        2. Incentive and Nonqualified Stock Options. Two types of options
(referred to herein as "options" without distinction between such two types) may
be granted under the Plan: options intended to qualify as incentive stock
options ("Incentive Stock Options") under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"); and other options not specifically
authorized or qualified for favorable income tax treatment by the Code
("Nonqualified Stock Options").

        3.     Administration.

        3.1 Administration by Board. Subject to Section 3.2, the Plan shall be
administered by the Board of Directors of the Company (the "Board"). Subject to
the provisions of the Plan, the Board shall have authority to construe and
interpret the Plan, to promulgate, amend, and rescind rules and regulations
relating to its administration, from time to time to select from among the
eligible employees (as determined pursuant to Section 4) of the Company and its
subsidiaries those employees to whom options will be granted, to determine the
timing and manner of the grant of the options, to determine the exercise price,
the number of shares covered by and all of the terms of the options, to
determine the duration and purpose of leaves of absence which may be granted to
optionees without constituting termination of their employment for purposes of
the Plan, and to make all of the determinations necessary or advisable for
administration of the Plan. The interpretation and construction by the Board of
any provision of the Plan, or of any grant or agreement issued and executed
under the Plan, shall be final and binding upon all parties. No member of the
Board shall be liable for any action or determination undertaken or made in good
faith with respect to the Plan or any agreement executed pursuant to the Plan.

        3.2 Administration by Committee. The Board may, in its sole discretion,
delegate any or all of its administrative duties to a committee appointed by the
Board (the "Committee") consisting of three Board members, each of whom, during
such time as one or more persons eligible to receive options under the Plan is
subject to Section 16 of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") shall be disinterested within the meaning of Rule 16b-3 under
the Exchange Act (or any successor rule, "Rule 16b-3") and shall qualify as
"outside directors" as defined in the regulations under Code Section 162(m),
provided, however, that the Board may from time to time increase the size of the
Committee, and add additional members to, or remove members from, the Committee.
The Committee shall act pursuant to a majority vote, or the written consent of a
majority of its members, and minutes shall be kept of all of its meetings and
copies thereof shall be provided to the Board. Subject to the provisions of the
Plan and the directions of the Board, the Committee may establish and follow
such rules and regulations for the conduct of its business as it may deem
advisable. No member of the Committee shall be liable for any action or
determination undertaken or made in good faith with respect to the Plan or any
agreement executed pursuant to the Plan. The Board or the Committee, as the case
may be, is sometimes referred to herein as the "Administrator."

        4. Eligibility. Any employee (including any officer who is an employee)
of the Company or any of its subsidiaries who does not own stock possessing more
than 10% of the total combined voting power of all outstanding shares of all
classes of stock of the Company or any of its parent or subsidiary corporations
shall be eligible to receive a grant or grants of such options under the Plan;
provided, however, that notwithstanding the foregoing, any employee of the
Company who owns stock possessing more than 10% of the total combined voting
power of all outstanding shares of all classes of stock of the Company or any of
its parent or subsidiary corporations shall be eligible to receive a grant or
grants of such options under the Plan if at the time such options are granted
the option exercise price therefor is at least 110% of the Fair Market Value (as
defined below) of the shares subject to the option and such option by its terms




                                       1
<PAGE>   2

is not exercisable after the expiration of five years from the date such option
is granted. An employee may receive more than one option under the Plan.
Notwithstanding the foregoing, no person who is a director of the Company shall
be eligible to receive an option under the Plan unless the granting of such
option shall be effected in such a manner as not to impair the Plan's
qualification under Rule 16b-3.

        5. Shares Subject to Options. The stock available for issuance upon
exercise of stock options granted under the Plan shall be shares of the
Company's authorized but unissued, or reacquired, Common Stock. The aggregate
number of shares that may be issued after September 5, 1985, pursuant to
exercise of options granted under the Plan shall not exceed 15,450,000 shares of
Common Stock (subject to adjustment as provided herein). In the event that any
outstanding option under the Plan for any reason expires or is terminated, the
shares of Common Stock allocable to the unexercised portion of the option shall
not count against the share limit set forth herein and shall again be available
for issuance upon exercise of stock options granted under the Plan as if no
option had been granted with respect to such shares.

        6.     Terms and Conditions of Options.

        6.1 Grants of Options. Subject to the express provisions of the Plan,
the Administrator shall from time to time in its discretion select those
individuals to whom options shall be granted, and shall determine the terms of
such options (which need not be identical) and the number of shares of Common
Stock for which each may be exercised. Notwithstanding anything to the contrary
herein, the number of shares of Common Stock with respect to which an option or
options may be granted to any optionee in any one taxable year of the Company
shall not exceed 400,000, subject to adjustment as provided herein (the "Maximum
Annual Employee Grant"). Each option shall be subject to the terms and
conditions of the Plan and such other terms and conditions established by the
Administrator as are not inconsistent with the purpose and provisions of the
Plan.

        6.2 Agreements or Confirming Memos. Options granted under the Plan may
but need not be evidenced by agreements (which need not be identical) in such
form and containing such provisions consistent with the Plan as the
Administrator shall from time to time approve. Options not documented by written
agreement shall be memorialized by a written confirming memorandum stating the
material terms of the option and provided to the option recipient. Each
agreement or confirming memorandum shall specify whether the subject option is
an Incentive Stock Option or a Nonqualified Stock Option.

        6.3 Optionee's Employment. Each optionee shall agree to remain in the
employ of, and to render services to, the Company or its subsidiaries for a
period of one year from the date the option is granted, but neither the Company
nor any of its subsidiaries shall be obligated to continue to employ the
optionee for any period.

        6.4 Option Exercise Price. The purchase price for the shares subject to
any option shall be determined by the Administrator but shall not be less than
100% of the Fair Market Value of the shares of Common Stock of the Company on
the date the option is granted. For purposes of the Plan, the "Fair Market
Value" of any share of Common Stock of the Company at any date shall be (a) if
the Common Stock is listed on an established stock exchange or exchanges, the
last reported sale price per share on such date on the principal exchange on
which it is traded, or if no sale was made on such date on such principal
exchange, at the closing reported bid price on such date on such exchange, or
(b) if the Common Stock is not then listed on an exchange, the average of the
closing bid and asked prices per share for the Common Stock in the
over-the-counter market as quoted on the Nasdaq National Market on such date, or
(c) if the Common Stock is not then listed on an exchange or quoted on the
Nasdaq National Market, an amount determined in good faith by the Administrator.

        6.5 Medium and Time of Payment. The purchase price for any shares
purchased pursuant to exercise of an option granted under the Plan shall be paid
in full upon exercise of the option in cash or such other consideration as the
Administrator may deem acceptable, including without limitation securities of
the Company (delivered by or on behalf of the person exercising the option or
retained by the Company from the stock otherwise issuable upon exercise and
valued at Fair Market Value as of the exercise date), provided, however, that
the Administrator may, in the exercise of its discretion, allow exercise of an
option in a broker-assisted or similar transaction in which the exercise price
is not received by the Company until promptly after exercise. Shares of Common
Stock transferred to the Company upon exercise of an option shall not increase
the number of shares available for issuance upon exercise of options granted
under the Plan. Notwithstanding the foregoing, the Company may extend and
maintain, or arrange for the extension 



                                       2
<PAGE>   3
and maintenance of, credit to any optionee to finance the optionee's purchase of
shares pursuant to exercise of any option, on such terms as may be approved by
the Administrator, subject to applicable regulations of the Federal Reserve
Board and any other laws or regulations in effect at the time such credit is
extended.

        6.6 Option Period and Vesting. Subject to Section 6.14, options granted
under the Plan shall vest and may be exercised as determined by the
Administrator, except that no option may vest and become exercisable at any time
prior to six months from the date the option is granted. Exercise of options
after termination of the optionee's employment shall be subject to Sections 6.13
and 6.14. Each option granted hereunder and all rights or obligations under such
option shall expire on such date as shall be determined by the Administrator,
but not later than ten years after the date the option is granted, or five years
after the date of grant in the case of an option recipient who at the time of
grant owns more than 10% of the total combined voting power of all outstanding
shares of all classes of stock of the Company or any of its parent or subsidiary
corporations, and shall be subject to earlier termination as herein provided.

        6.7 Exercise of Options. To the extent that an optionee has the right to
exercise an option, the option may be exercised from time to time by written
notice to the Company stating the number of shares being purchased and
accompanied by payment in full of the purchase price for such shares, except
that in no event shall the Company be required to issue fractional shares upon
the exercise of an option, and the Administrator may, in its discretion, require
that any exercise of an option be for at least 100 shares or, if less, the total
number of shares for which the option is then exercisable. Any certificate(s)
for outstanding securities of the Company used to pay the purchase price shall
be accompanied by stock power(s) duly endorsed in blank by the registered holder
of the certificate(s). In the event the certificate(s) tendered by the optionee
in such payment cover more shares than are required for such payment, the
certificate(s) shall also be accompanied by instructions from the optionee to
the Company's transfer agent with respect to disposition of the balance of the
securities covered thereby. Notwithstanding any other provision of this Plan,
the Administrator may impose such conditions upon the exercise of options
(including, without limitation, conditions limiting the time of exercise to
specified periods) as may be required to satisfy applicable regulatory
requirements, including without limitation Rule 16b-3, other relevant securities
laws and rules, and any applicable section of or rule under the Code. Whenever
shares of stock are to be issued upon exercise of an option granted under the
Plan or subsequently transferred, the Administrator shall have the right to
require the optionee or transferor to remit to the Company an amount sufficient
to satisfy any federal, state and local withholding tax requirements prior to
the delivery of any certificate or certificates for such shares. The
Administrator may, in the exercise of its discretion, allow satisfaction of tax
withholding requirements by accepting delivery of securities of the Company or
by withholding a portion of the stock otherwise issuable upon exercise of an
option.

        6.8 Nonassignability. No option granted under the Plan shall be
assignable or transferable except (i) by will or by the laws of descent and
distribution, or (ii) subject to the final sentence of this Section 6.8, upon
dissolution of marriage pursuant to a property settlement or domestic relations
order, or (iii) as permitted on a case-by-case basis in the discretion of, and
subject to such conditions as may be imposed by, the Administrator to permit
transfers to immediate family members, family trusts or family foundations of
the grantee under circumstances that would not adversely affect the interests of
the Company. During the lifetime of an optionee, an option granted to him or her
shall be exercisable only by the optionee (or the optionee's permitted
transferee) or his or her guardian or legal representative. Notwithstanding the
foregoing, Incentive Stock Options may not be assigned or transferred in
violation of Section 422(b)(5) of the Code (or any successor provision) or the
Treasury Regulations thereunder, and nothing herein is intended to allow such
assignment or transfer."

        6.9 Limit on Incentive Stock Options. Subject to Section 12.1, the
aggregate Fair Market Value (determined as of the time the option is granted) of
the stock for which Incentive Stock Options granted to any one employee under
all stock option plans of the Company and its parent and subsidiary corporations
first become exercisable during any calendar year after December 31, 1986 shall
not exceed $100,000.

        6.10 Restriction on Issuance of Shares. The issuance of options and
shares shall be subject to compliance with all of the applicable requirements of
law with respect to the issuance and sale of securities, including, without
limitation, any required qualification under the California Corporate Securities
Law of 1968, as amended.

        6.11 Investment Representation. Any optionee may be required, as a
condition of issuance of shares covered by his or her option, to represent that
the shares to be acquired pursuant to exercise of the option will be 



                                       3
<PAGE>   4

acquired for investment and without a view to distribution thereof; and in such
case, the Company may place a legend on the certificate evidencing the shares
reflecting the fact that they were acquired for investment and cannot be sold or
transferred unless registered under the Securities Act of 1933, as amended, or
unless counsel for the Company is satisfied that the circumstances of the
proposed transfer do not require such registration, and in addition, the Company
may issue stop transfer instructions to the transfer agent of the Company's
securities restricting the transfer of such shares.

        6.12 Rights as a Shareholder or Employee. An optionee or transferee of
an option shall have no rights as a shareholder of the Company with respect to
any shares covered by any option until (i) the Company has received all amounts
payable in connection with the exercise of the option, including the exercise
price and any amounts required by the Company to satisfy tax withholding
requirements, and (ii) a share certificate for such shares has been issued. No
adjustment shall be made for dividends (ordinary or extraordinary, whether cash,
securities, or other property) or distributions or other rights for which the
record date is prior to the date such share certificate is issued, except as
provided in Section 6.15. Nothing in the Plan or in any grant or option
agreement shall confer upon any employee any right to continue in the employ of
the Company or any of its subsidiaries or interfere in any way with any right of
the Company or any subsidiary to terminate the optionee's employment at any
time.

        6.13 Termination of Employment, Disability, or Death. In general,
subject to Section 6.14, options shall be exercisable by an optionee (or his or
her permitted successor in interest) following such optionee's termination of
employment only to the extent that such options had become exercisable on or
prior to the date of such termination. In the event an optionee ceases to be an
employee of the Company and its subsidiaries for any reason (other than cause)
while still living, any option or unexercised portion thereof granted to the
optionee may, to the extent such option was exercisable by the optionee on or
prior to the date he or she ceased to be an employee (or is accelerated pursuant
to Section 6.14 to a date within three months of termination of employment), be
exercised by the optionee within three months of the date on which he or she
ceased to be an employee, but in any event not later than the date of expiration
of the option. In the event of the death or disability (as defined in Section
105(d)(4) of the Code) of the optionee while he or she is an employee of the
Company or any of its subsidiaries or within not more than three months of the
date on which he or she ceased to be an employee for any reason other than
cause, any option or unexercised portion thereof granted to the optionee may, to
the extent such option was exercisable by the optionee on or prior to the date
of death or disability (or is accelerated pursuant to Section 6.14 to a date
within the period during which such option may be exercised as set forth below),
be exercised by the optionee or, if the optionee is then deceased or
incapacitated, by the optionee's personal representatives, heirs, or legatees at
any time prior to the later of (i) one year from the date on which the optionee
ceased to be an employee or (ii) the latest date the option could have been
exercised by the optionee if not disabled or dead, but in any event, not later
than the date of expiration of the option. Notwithstanding the foregoing,
however, if an optionee's employment with the Company and its subsidiaries is
terminated for cause, as determined by the Administrator in its sole discretion,
all options held by such optionee shall expire on the date of termination of
employment and thereafter shall not be exercisable in whole or in part.

        6.14 Modification, Extension, and Renewal of Options; Alteration of
Vesting and Exercise Periods. Subject to the terms and conditions and within the
specific limitations of the Plan, the Administrator may modify, extend, or renew
outstanding options granted under the Plan, accept the surrender of outstanding
options (to the extent not theretofore exercised), and authorize the granting of
new options in substitution therefor (to the extent not theretofore exercised)
except that no such modification, extension or renewal shall result in a
reduction in the exercise price of such option. Without limitation of the
foregoing and notwithstanding anything in this Plan to the contrary, the
Administrator may at any time and from time to time in its discretion (i)
designate shorter or longer periods than specified herein or in any particular
option grant or agreement following the termination of an optionee's employment
with the Company or any of its subsidiaries or the optionee's death or
disability during which the optionee may exercise options, provided, however,
that any shorter periods determined by the Administrator shall be effective only
if determined at the time of the grant of the affected option or if such shorter
period is agreed to in writing by the optionee, and any longer periods may not
extend beyond the original termination date of the affected option; (ii) subject
to the six-month minimum vesting period described in Section 6.6, accelerate
vesting of an option in whole or part by increasing the number of shares
purchasable at any particular time, provided that no such acceleration shall
increase the total number of shares for which the option may be exercised; and
(iii) extend the period after death or disability or termination of employment
during which vesting of all or any portion of any options that had not become
exercisable on or prior to the date thereof may occur. Notwithstanding the
foregoing, no option shall be modified in such a manner 



                                       4
<PAGE>   5

as to impair any rights of the optionee under the option, or to cause an
Incentive Stock Option to cease to qualify as such, without the consent of the
optionee.

        6.15 Recapitalization or Reorganization of the Company. Except as
otherwise provided herein, appropriate and proportionate adjustments shall be
made in the number and class of shares subject to the Plan, the Maximum Annual
Employee Grant, the option rights granted under the Plan, and the exercise price
of such option rights, in the event of a stock dividend (but only on Common
Stock), stock split, reverse stock split, recapitalization, reorganization,
merger, consolidation, separation, or like change in the capital structure of
the Company affecting the Common Stock of the Company. In the event of a
liquidation of the Company, or a merger, reorganization, or consolidation of the
Company with any other corporation in which the Company is not the surviving
corporation or the Company becomes a wholly-owned subsidiary of another
corporation, any unexercised options theretofore granted under the Plan shall be
deemed canceled unless the surviving corporation in any such merger,
reorganization, or consolidation elects to assume the options under the Plan or
to issue substitute options in place thereof; provided, however, that,
notwithstanding the foregoing, if such options would otherwise be canceled in
accordance with the foregoing, the optionee shall have the right, exercisable
during a ten-day period ending on the fifth day prior to such liquidation,
merger, reorganization, or consolidation, to exercise the optionee's option in
whole or in part without regard to any installment exercise provisions in the
optionee's option agreement. To the extent that the foregoing adjustments relate
to stock or securities of the Company, such adjustments shall be made by the
Administrator, the determination of which in that respect shall be final,
binding, and conclusive, provided that an Incentive Stock Option shall not
without the consent of the optionee be adjusted in a manner that causes the
option to fail to continue to qualify as an Incentive Stock Option.

        7. Termination or Amendment of Plan. The Board or the Committee may at
any time or from time to time suspend, terminate or amend the Plan; provided
that, without approval of the shareholders of the Company, there shall be,
except as specifically permitted by the Plan, no increase in the total number of
shares issuable upon exercise of options granted under the Plan, no change in
the class of persons eligible to receive options granted under the Plan, and no
extension of the latest date upon which options may be granted under the Plan;
and provided further that, without the consent of the optionee, no amendment may
adversely affect any then outstanding option or any unexercised portion thereof
without the consent of the holder of such option.

        8. Indemnification. In addition to such other rights of indemnification
as they may have as members of the Board or the Committee, the members of the
Board or the Committee administering the Plan shall be indemnified by the
Company against reasonable expenses, including attorney's fees, actually and
necessarily incurred in connection with the defense of any action, suit, or
proceeding, or in connection with any appeal therein, to which they or any of
them may be a party by reason of any action taken or failure to act under or in
connection with the Plan or any option granted thereunder, and against all
amounts paid by them in settlement thereof (provided such settlement is approved
by independent legal counsel selected by the Company) or paid by them in
satisfaction of a judgment in any action, suit, or proceeding, except in
relation to matters as to which it shall be adjudged in such action, suit, or
proceeding that such member is liable for negligence or misconduct in the
performance of his or her duties, provided that within 60 days after institution
of any such action, suit, or proceeding, the member shall in writing offer the
Company the opportunity, at its own expense, to handle and defend the same.

        9. 1978 Nonqualified Stock Option Plan. The Plan as set forth herein
constitutes an amendment and restatement of the Company's 1978 Nonqualified
Stock Option Plan which was adopted in 1978. The Administrator may, in its
discretion, authorize the conversion, to the fullest extent permitted by law, of
Nonqualified Stock Options granted under the 1978 Nonqualified Stock Option Plan
prior to such amendment to Incentive Stock Options under this Plan, as so
amended. Any such options converted to Incentive Stock Options shall be treated
as Incentive Stock Options for all purposes under the Plan; provided, however,
that none of the terms or conditions of any of such options, including, but not
limited to, the exercise price, the term of the option, and the time(s) within
which the option may be exercised, shall be altered or amended by reason of such
conversion.

        10. Options Granted Prior to Amendment and Restatement. The Plan, as
amended and restated from time to time, shall, in the discretion of the
Administrator, apply to and govern options granted under the Plan prior to the
date of any such amendment or restatement, subject to the consent of any holder
of an option who would be disadvantaged by application to such option of the
Plan as amended and restated after the grant of such option.


                                       5
<PAGE>   6
        11. Term of Plan. Unless sooner terminated by the Board or the Committee
in its sole discretion, the Plan will expire on November 10, 2004 (the
"Termination Date"). Options may be granted under the Plan until midnight on the
Termination Date, whereupon the Plan shall terminate. No options may be granted
during any suspension of the Plan or after its termination. Notwithstanding the
foregoing, each option properly granted under the Plan shall remain in effect
until such option has been exercised or terminated in accordance with its terms
and the terms of the Plan.

        12.    Miscellaneous.

        12.1 Plan Provisions Regarding Incentive Stock Options. Options
originally granted as Incentive Stock Options but that subsequently become
Nonqualified Stock Options need not satisfy any requirements of the Plan
applicable to Incentive Stock Options.

        12.2 Other Compensation Plans. The adoption of this Plan shall not
affect any other stock option, incentive, or compensation plans in effect for
the Company or any of its subsidiaries, and the Plan shall not preclude the
Company or any of its subsidiaries from establishing any other forms of
incentive compensation for employees, directors, or advisors of the Company or
any of its subsidiaries.

           reason other than death, Disability or Termination of
           Employment or on or after a Participant attains the age of

                             FIFTH AMENDMENT TO THE
                           WESTERN DIGITAL CORPORATION
                   RETIREMENT SAVINGS AND PROFIT SHARING PLAN


        This Fifth Amendment (the "Amendment") to the Western Digital
Corporation Retirement Savings and Profit Sharing Plan (the "Plan") is made this
13th day of November 1997 by Western Digital Corporation (the "Company"), the
sponsoring employer of the Plan.

        WHEREAS, the terms of the Plan are set forth in an amended and restated
Plan document, dated June 23, 1995, as thereafter amended by the First Amendment
dated June 30, 1995, by the Second Amendment dated March 27, 1996, by the Third
Amendment dated January 9, 1997 and by the Fourth Amendment dated March 20,
1997; and

        WHEREAS, the Company has reserved the right to amend the Plan by action
of its Board of Directors; and

        WHEREAS, it is deemed desirable to amend the Plan in certain respects;

        NOW, THEREFORE, the Plan is amended as follows:

        1. Section 2.14 "Eligible Employee" shall be amended to read in its
entirety as follows:

        2.14 ELIGIBLE EMPLOYEE

                  2.14.1   "Eligible Employee" shall mean any Employee of an
                           Employer who is paid from the Employer's United
                           States payroll, except as provided in Subsection
                           2.14.2 below.

                  2.14.2   The term "Eligible Employee" shall not include any
                           person in one or more of the following categories:

                           2.14.2.1 Any person who is covered by a collective
                                    bargaining agreement to which an Employer is
                                    a party, unless the collective bargaining
                                    agreement provides for coverage under this
                                    Plan.

                           2.14.2.2 Any non-resident alien who receives no
                                    earned income (within the meaning of Code
                                    Section 911(d)(2)) from Employer that
                                    constitutes income from sources within the

                                    Section 861(a)(3)).

                                    records of an Employer or an Affiliated
                                    Company as an independent contractor or
                                    consultant, a worker provided by a temporary
                                    staffing agency, a temporary employee, or an
                                    individual with respect to whom a written
                                    agreement governing the relationship between
                                    such person and an Employer or Affiliated
                                    Company provides in substance that such
                                    person shall not be an Eligible Employee
                                    hereunder.

                  2.14.3   The preceding provisions of this Section 2.14 shall
                           be given effect notwithstanding any classification or
                           reclassification of a person as an employee or common
                           law employee of an Employer or Affiliated Company or
                           as a member of any other category of person not
                           excluded under the preceding provisions of this
                           Section 2.14 by reason of action taken by any tax, or
                           other governmental authority. In the event that a
                           person rendering services to an Employer or to an
                           Affiliated Company in an excluded category is
                           classified or reclassified by reason of action taken
                           by any tax, or other governmental authority, or by an
                           Employer or Affiliated Company, such individual shall
                           continue to be excluded under this Plan unless
                           specifically included hereunder by the terms of an
                           amendment to this Plan or by the terms of a written
                           instrument executed by such person and an Employer.

                  2.14.4   The categories of excluded persons described above in
                           this Section 2.14 are not mutually exclusive, it
                           being contemplated that certain categories described
                           above may include persons in one or more other
                           categories, with the result that an individual may be
                           excluded under more than one category set forth
                           herein.

         This Amendment shall be effective as of June 23, 1995.

         2. Section 2.15 "Employee" shall be amended to read in its entirety as
follows:

         2.15 EMPLOYEE

                  2.15.1   "Employee" shall mean each person currently employed
                           in any capacity by an Employer or Affiliated Company,
                           any portion of whose Compensation paid by an Employer
                           or an Affiliated Company is subject to withholding

                           of income tax and/or for whom Social Security
                           contributions are made by an Employer or an
                           Affiliated Company.

                  2.15.2   "Employee" shall include a person deemed to be
                           employed by an Employer or an Affiliated Company,
                           pursuant to Code Section 414(n). Notwithstanding the
                           foregoing, if such leased employees constitute less
                           than twenty percent (20%) of the Company's non-highly
                           compensated work force within the meaning of Section
                           414(n)(5)(C)(ii) of the Code, the term "Employee"
                           shall not include those leased employees covered by a
                           plan described in Section 414(n)(5) of the Code
                           unless otherwise provided by the terms of the Plan.

                  2.15.3   Although Eligible Employees are the only class of
                           individuals eligible to participate in this Plan, the
                           term "Employee" is used to refer to persons employed
                           in a non-eligible Employee capacity as well as
                           Eligible Employee category. Thus, those provisions of
                           this Plan that are not limited to Eligible Employees,
                           such as those relating to certain service computation
                           rules, apply to both Eligible and non-Eligible
                           Employees.

         This Amendment shall be effective as of June 23, 1995.

         IN WITNESS WHEREOF, the Company has caused this Amendment to be
executed by its duly authorized officer on this 13th day of November 1997.

between the Closing Date and 

<PAGE>   29



                                      -22-

the Revolving Credit Loan Maturity Date upon notice by the Borrower to the Agent
given in accordance with ss.2.6, such sums as are requested by the Borrower up
to a maximum aggregate amount outstanding (after giving effect to all amounts
requested) at any one time equal to such Bank's Commitment minus such Bank's
Commitment Percentage of the sum of the Maximum Drawing Amount and all Unpaid
Reimbursement Obligations, provided that the sum of the outstanding amount of
the Revolving Credit Loans (after giving effect to all amounts requested) plus
the Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall not at
any time exceed the lesser of (a) the Total Commitment and (b) the Borrowing
Base. The Revolving Credit Loans shall be made pro rata in accordance with each
Bank's Commitment Percentage. Each request for a Revolving Credit Loan hereunder
shall constitute a representation and warranty by the Borrower that the
conditions set forth in ss.12 and ss.13, in the case of the initial Revolving
Credit Loans to be made on the Closing Date, and ss.13, in the case of all other
Revolving Credit Loans, have been satisfied on the date of such request.

         2.2. COMMITMENT FEE. The Borrower agrees to pay to the Agent for the
accounts of the Banks in accordance with their respective Commitment Percentages
a commitment fee (the "Commitment Fee") calculated at the applicable Commitment
Fee Rate on the average daily amount during each calendar quarter or portion
thereof from the Closing Date to the Revolving Credit Loan Maturity Date by
which the Total Commitment minus the sum of the Maximum Drawing Amount and all
Unpaid Reimbursement Obligations exceeds the outstanding amount of Revolving
Credit Loans during such calendar quarter. The Commitment Fee shall be payable
quarterly in arrears on the first day of each calendar quarter for the
immediately preceding calendar quarter commencing on the first such date
following the date hereof, with a final payment on the Revolving Credit Maturity
Date or any earlier date on which the Commitments shall terminate.

         2.3. REDUCTION OF TOTAL COMMITMENT. The Borrower shall have the right
at any time and from time to time upon five (5) Business Days prior written
notice to the Agent to reduce by $5,000,000 or a whole multiple of $500,000 in
excess thereof or terminate entirely the Total Commitment, whereupon the
Commitments of the Banks shall be reduced pro rata in accordance with their
respective Commitment Percentages of the amount specified in such notice or, as
the case may be, terminated. Promptly after receiving any notice of the Borrower
delivered pursuant to this ss.2.3, the Agent will notify the Banks of the
substance thereof. Upon the effective date of any such reduction or termination,
the Borrower shall pay to the Agent for the respective accounts of the Banks the
full amount of any Commitment Fee then accrued on the amount of the reduction.
No reduction or termination of the Commitments may be reinstated.

         2.4. THE REVOLVING CREDIT NOTES. The Revolving Credit Loans shall be
evidenced by separate promissory notes of the Borrower in substantially the form
of Exhibit B hereto (each a "Revolving Credit Note"), dated as of the Closing
Date and completed with appropriate insertions. One Revolving Credit Note shall
be payable to the order of each Bank in a principal amount equal to such Bank's
Commitment or, if less, the outstanding amount of all Revolving Credit Loans
made by such Bank, plus interest accrued thereon, as set forth below. The
Borrower irrevocably authorizes each Bank to make or cause to be made, at or
about the time of the Drawdown Date of any Revolving Credit Loan or at the time
of receipt of any payment of principal on such Bank's Revolving Credit Note, an

<PAGE>   30



                                      -23-


appropriate notation on such Bank's Revolving Credit Note Record reflecting the
making of such Revolving Credit Loan or (as the case may be) the receipt of such
payment. The outstanding amount of the Revolving Credit Loans set forth on such
Bank's Revolving Credit Note Record shall be prima facie evidence of the
principal amount thereof owing and unpaid to such Bank, but the failure to
record, or any error in so recording, any such amount on such Bank's Revolving
Credit Note Record shall not limit or otherwise affect the obligations of the
Borrower hereunder or under any Revolving Credit Note to make payments of
principal of or interest on any Revolving Credit Note when due.

         2.5.  INTEREST ON REVOLVING CREDIT LOANS.  Except as otherwise provided
in ss.6.11,

                  (a) Each Base Rate Loan shall bear interest for the period
         commencing with the Drawdown Date thereof and ending on the last day of
         the Interest Period with respect thereto at the rate per annum equal to
         the Base Rate plus the Applicable Margin.

                  (b) Each Eurodollar Rate Loan shall bear interest for the
         period commencing with the Drawdown Date thereof and ending on the last
         day of the Interest Period with respect thereto at the rate per annum
         equal to the Eurodollar Rate determined for such Interest Period plus
         the Applicable Margin.

                  (c) The Borrower promises to pay interest on each Revolving
         Credit Loan in arrears on each Interest Payment Date with respect
         thereto.

         2.6. REQUESTS FOR REVOLVING CREDIT LOANS. The Borrower shall give to
the Agent written notice in the form of Exhibit C hereto (or telephonic notice
confirmed in a writing in the form of Exhibit C hereto) of each Revolving Credit
Loan requested hereunder (a "Loan Request") not later than (a) 11:00 a.m.
(Boston time) on the proposed Drawdown Date of any Base Rate Loan and (b) 11:00
a.m. (Boston time) two (2) Eurodollar Business Days prior to the proposed

the principal amount of the Revolving Credit Loan requested, (ii) the proposed
Drawdown Date of such Revolving Credit Loan, (iii) the Interest Period for such
Revolving Credit Loan and (iv) the Type of such Revolving Credit Loan. Promptly
upon receipt of any such notice, the Agent shall notify each of the Banks
thereof. Each Loan Request shall be irrevocable and binding on the Borrower and
shall obligate the Borrower to accept the Revolving Credit Loan requested from
the Banks on the proposed Drawdown Date. Each Loan Request shall for a Base Rate
Loan shall be in a minimum aggregate amount of $1,000,000 or a larger integral
multiple of $100,000 in excess thereof, and each Loan Request for a Eurodollar
Rate Loan shall be in a minimum aggregate amount of $5,000,000 or a larger

         provided that (a) with respect to any such conversion of a Revolving
         Credit Loan to a Base Rate Loan, the Borrower shall give the Agent at

         converted into a Eurodollar Rate Loan when any Default or Event of

         necessary to transfer its Commitment Percentage of such Revolving
         Credit Loans to its Domestic Lending Office or its Eurodollar Lending
         Office, as the case may be. All or any part of outstanding Revolving
         Credit Loans of any Type may be converted into a Revolving Credit Loan

         amount of $1,000,000 or a larger integral multiple of $100,000 in
         excess thereof, and any partial conversion into a Eurodollar Rate Loan
         shall be in an aggregate principal amount of $5,000,000 or a larger
         integral multiple of $1,000,000 in excess thereof. Each Conversion
         Request relating to the conversion of a Revolving Credit Loan to a
         Eurodollar Rate Loan shall be irrevocable by the Borrower.

                  2.7.2. CONTINUATION OF TYPE OF REVOLVING CREDIT LOAN. Any
         Revolving Credit Loan of any Type may be continued as a Revolving
         Credit Loan of the same Type upon the expiration of an Interest Period
         with respect thereto by compliance by the Borrower with the notice
         provisions contained in ss.2.7.1; provided that no Eurodollar Rate Loan
         may be continued as such when any Default or Event of Default has
         occurred and is continuing, but shall be automatically converted to a
         Base Rate Loan on the last day of the first Interest Period relating
         thereto ending during the continuance of any Default or Event of
         Default; and provided, further, to the extent any Revolving Credit Loan
         was converted or continued as a Eurodollar Rate Loan on a date when the
         Borrower was unable to satisfy the conditions set forth in ss.13
         hereof, such Loan may not be continued as such if on the date of such
         conversion the Borrower remains unable to satisfy the conditions set
         forth in ss.13 hereof, but shall be automatically converted to a Base
         Rate Loan on the last day of the Interest Period relating thereto. In
         the event that the Borrower fails to provide any such notice with
         respect to the continuation of any Eurodollar Rate Loan as such, then
         such Eurodollar Rate Loan shall be automatically converted to a Base
         Rate Loan on the last day of the first Interest Period relating
         thereto. The Agent 

<PAGE>   32




                                      -25-

         shall notify the Banks promptly when any such automatic conversion 
         comtemplated by this ss.2.7 is scheduled to occur.

                  2.7.3. EURODOLLAR RATE LOANS. Any conversion to or from
         Eurodollar Rate Loans shall be in such amounts and be made pursuant to
         such elections so that, after giving effect thereto, the aggregate
         principal amount of all Eurodollar Rate Loans having the same Interest
         Period shall not be less than $5,000,000 or an integral multiple of
         $1,000,000 in excess thereof. In addition, there shall not be more than
         fifteen (15) Eurodollar Rate Loans outstanding at any one time.

         2.8.  FUNDS FOR REVOLVING CREDIT LOAN.

                  2.8.1. FUNDING PROCEDURES. Not later than 1:00 p.m. (Boston
         time) on the proposed Drawdown Date of any Revolving Credit Loans, each
         of the Banks will make available to the Agent, at the Agent's Head
         Office, in immediately available funds, the amount of such Bank's
         Commitment Percentage of the amount of the requested Revolving Credit
         Loans. Upon receipt from each Bank of such amount, and upon receipt of
         the documents required by ss.ss.12 and 13 and the satisfaction of the
         other conditions set forth therein, to the extent applicable, the Agent
         will make available to the Borrower the aggregate amount of such
         Revolving Credit Loans made available to the Agent by the Banks. The
         failure or refusal of any Bank to make available to the Agent at the
         aforesaid time and place on any Drawdown Date the amount of its
         Commitment Percentage of the requested Revolving Credit Loans shall not
         relieve any other Bank from its several obligation hereunder to make
         available to the Agent the amount of such other Bank's Commitment
         Percentage of any requested Revolving Credit Loans.

                  2.8.2. ADVANCES BY AGENT. The Agent may, unless notified to
         the contrary by any Bank prior to a Drawdown Date, assume that such
         Bank has made available to the Agent on such Drawdown Date the amount
         of such Bank's Commitment Percentage of the Revolving Credit Loans to
         be made on such Drawdown Date, and the Agent may (but it shall not be
         required to), in reliance upon such assumption, make available to the
         Borrower a corresponding amount. If any Bank makes available to the
         Agent such amount on a date after such Drawdown Date, such Bank shall
         pay to the Agent on demand an amount equal to the product of (a) the
         average computed for the period referred to in clause (c) below, of the
         weighted average interest rate paid by the Agent for federal funds
         acquired by the Agent during each day included in such period, times
         (b) the amount of such Bank's Commitment Percentage of such Revolving
         Credit Loans, times (c) a fraction, the numerator of which is the
         number of days that elapse from and including such Drawdown Date to the
         date on which the amount of such Bank's Commitment Percentage of such
         Revolving Credit Loans shall become immediately available to the Agent,
         and the denominator of which is 360. A statement of the Agent submitted
         to such Bank with respect to any amounts owing under this paragraph
         shall be prima facie evidence of the amount due and owing to the Agent
         by such Bank. If the amount of such Bank's Commitment Percentage of
         such Revolving Credit Loans is not made available to the Agent by such
         Bank within three (3) Business Days following such Drawdown Date, the
         Agent shall be entitled to recover such amount from the 

<PAGE>   33




                                      -26-

         Borrower on demand, with interest thereon at the rate per annum 
         applicable to the Revolving Credit Loans made on such Drawdown Date.

         2.9. CHANGE IN BORROWING BASE. The Borrowing Base shall be determined
monthly (or at such other interval as may be specified pursuant to ss.9.4(e)) by
the Agent by reference to the Borrowing Base Report delivered to the Banks and
the Agent pursuant to ss.9.4(e) and other information obtained by or provided to
the Agent. The Agent shall give to the Borrower written notice of any change in
the Borrowing Base determined by the Agent. In the case of a reduction in the
lending formula with respect to Eligible Accounts Receivable, such notice shall
be effective thirty (30) days after its receipt by the Borrower, and in the case
of any change in the general criteria for Eligible Accounts Receivable, such
notice shall be effective upon its receipt by the Borrower. Prior to the time
that such notice becomes effective the Borrowing Base shall be computed as it
would have been computed in the absence of such notice.

                   3. REPAYMENT OF THE REVOLVING CREDIT LOANS.

         3.1. MATURITY. The Borrower promises to pay on the Revolving Credit
Loan Maturity Date, and there shall become absolutely due and payable on the
Revolving Credit Loan Maturity Date, all of the Revolving Credit Loans
outstanding on such date, together with any and all accrued and unpaid interest
thereon.

         3.2. MANDATORY REPAYMENTS OF REVOLVING CREDIT LOANS. If at any time the
sum of the outstanding amount of the Revolving Credit Loans, the Maximum Drawing
Amount and all Unpaid Reimbursement Obligations exceeds the lesser of (a) the
Total Commitment and (b) the Borrowing Base, then the Borrower shall immediately
pay the amount of such excess to the Agent for the respective accounts of the
Banks for application: first, to any Unpaid Reimbursement Obligations; second,
to the Revolving Credit Loans; and third, to provide to the Agent cash
collateral for Reimbursement Obligations as contemplated by ss.5.2(b) and (c).
Each payment of any Unpaid Reimbursement Obligations or prepayment of Revolving
Credit Loans shall be allocated among the Banks, in proportion, as nearly as
practicable, to each Reimbursement Obligation or (as the case may be) the
respective unpaid principal amount of each Bank's Revolving Credit Note, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion.

         3.3. OPTIONAL REPAYMENTS OF REVOLVING CREDIT LOANS. The Borrower shall
have the right, at its election, to repay the outstanding amount of the
Revolving Credit Loans, as a whole or in part, at any time without penalty or
premium, but subject to ss.6.10. The Borrower shall give the Agent, no later
than 1:00 p.m., Boston time, at least one (1) Business Day prior written notice
of any proposed prepayment pursuant to this ss.3.3 of Base Rate Loans, and two
(2) Eurodollar Business Days notice of any proposed prepayment pursuant to this
ss.3.3 of Eurodollar Rate Loans, in each case specifying the proposed date of
prepayment of Revolving Credit Loans and the principal amount to be prepaid.
Each such partial prepayment of the Revolving Credit Loans shall be in a minimum
amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and
shall be applied, in the absence of instruction by the Borrower, first to the
principal of Base Rate Loans and then to the principal of Eurodollar Rate Loans.
Each partial prepayment shall be allocated among the Banks, in proportion, as
nearly as practicable, to the respective unpaid principal 

<PAGE>   34



                                      -27-

amount of each Bank's Revolving Credit Note, with adjustments to the extent
practicable to equalize any prior repayments not exactly in proportion.

                                4. THE TERM LOAN.

         4.1. COMMITMENT TO LEND. Subject to the terms and conditions set forth
in this Credit Agreement, each Bank agrees to lend to the Borrower on the
Closing Date the amount of its Commitment Percentage of the principal amount of
$50,000,000.

         4.2. THE TERM NOTES. The Term Loan shall be evidenced by separate
promissory notes of the Borrower in substantially the form of Exhibit D hereto
(each a "Term Note"), dated the Closing Date and completed with appropriate
insertions. One Term Note shall be payable to the order of each Bank in a
principal amount equal to such Bank's Commitment Percentage of the Term Loan and
representing the obligation of the Borrower to pay to such Bank such principal
amount or, if less, the outstanding amount of such Bank's Commitment Percentage
of the Term Loan, plus interest accrued thereon, as set forth below. The
Borrower irrevocably authorizes each Bank to make or cause to be made a notation
on such Bank's Term Note Record reflecting the original principal amount of such
Bank's Commitment Percentage of the Term Loan and, at or about the time of such
Bank's receipt of any principal payment on such Bank's Term Note, an appropriate
notation on such Bank's Term Note Record reflecting such payment. The aggregate
unpaid amount set forth on such Bank's Term Note Record shall be prima facie
evidence of the principal amount thereof owing and unpaid to such Bank, but the
failure to record, or any error in so recording, any such amount on such Bank's
Term Note Record shall not affect the obligations of the Borrower hereunder or
under any Term Note to make payments of principal of and interest on any Term
Note when due.

         4.3. SCHEDULE OF INSTALLMENT PAYMENTS OF PRINCIPAL OF TERM LOAN. The
Borrower promises to pay to the Agent for the account of the Banks the principal
amount of the Term Loan in one payment of $50,000,000, which payment shall be
due and payable on the Term Loan Maturity Date in an amount equal to the unpaid
balance of the Term Loan.

         4.4. OPTIONAL PREPAYMENT OF TERM LOAN. The Borrower shall have the
right at any time to prepay the Term Notes on or before the Term Loan Maturity
Date, as a whole, or in part, upon not less than five (5) Business Days prior
written notice to the Agent, without premium or penalty but subject to ss.6.10,
provided that (a) each partial prepayment shall be in the principal amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof, and (b) each
partial prepayment shall be allocated among the Banks, in proportion, as nearly
as practicable, to the respective outstanding amount of each Bank's Term Note,
with adjustments to the extent practicable to equalize any prior prepayments not
exactly in proportion. Any prepayment of principal of the Term Loan shall
include all interest accrued to the date of prepayment and shall be applied
against the scheduled installments of principal due on the Term Loan in the
inverse order of maturity. No amount repaid with respect to the Term Loan may be
reborrowed.

         4.5. INTEREST ON TERM LOAN.

<PAGE>   35




                                      -28-


                  4.5.1. INTEREST RATES. Except as otherwise provided in
         ss.6.11, the Term Loan shall bear interest during each Interest Period
         relating to all or any portion of the Term Loan at the following rates:

                           (a) To the extent that all or any portion of the Term
                  Loan bears interest during such Interest Period at the Base
                  Rate, the Term Loan or such portion shall bear interest during
                  such Interest Period at the rate per annum equal to the Base
                  Rate plus the Applicable Margin.

                           (b) To the extent that all or any portion of the Term
                  Loan bears interest during such Interest Period at the
                  Eurodollar Rate, the Term Loan or such portion shall bear
                  interest during such Interest Period at the rate of per annum
                  equal to the Eurodollar Rate determined for such Interest
                  Period plus the Applicable Margin.

         The Borrower promises to pay interest on the Term Loan or any portion
         thereof outstanding during each Interest Period in arrears on each
         Interest Payment Date applicable to such Interest Period.

                  4.5.2. NOTIFICATION BY BORROWER. The Borrower shall notify the
         Agent, such notice to be irrevocable, at least three (3) Eurodollar
         Business Days prior to the Drawdown Date of the Term Loan if all or any
         portion of the Term Loan is to bear interest at the Eurodollar Rate.
         After the Term Loan has been made, the provisions of ss.2.7 shall apply
         mutatis mutandis with respect to all or any portion of the Term Loan so
         that the Borrower may have the same interest rate options with respect
         to all or any portion of the Term Loan as it would be entitled to with
         respect to the Revolving Credit Loans.

                  4.5.3. AMOUNTS, ETC. Any portion of the Term Loan bearing
         interest at the Eurodollar Rate relating to any Interest Period shall
         be in the amount of $5,000,000 or an integral multiple thereof. No
         Interest Period relating to the Term Loan or any portion thereof
         bearing interest at the Eurodollar Rate shall extend beyond the date on
         which a regularly scheduled installment payment of the principal of the
         Term Loan is to be made unless a portion of the Term Loan at least
         equal to such installment payment has an Interest Period ending on such
         date or is then bearing interest at the Base Rate.

                              5. LETTERS OF CREDIT.

         5.1. LETTER OF CREDIT COMMITMENTS.

                  5.1.1. COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject to the
         terms and conditions hereof and the execution and delivery by the
         Borrower of a letter of credit application on the Agent's customary
         form (a "Letter of Credit Application"), the Agent on behalf of the
         Banks and in reliance upon the agreement of the Banks set forth in
         ss.5.1.4 and upon the representations and warranties of the Borrower
         contained herein, agrees, in its individual capacity, to issue, extend
         and renew for the account of the Borrower one or more standby letters
         of credit (individually, a "Letter of Credit"), denominated in Dollars
         or any Optional Currency in such form 

<PAGE>   36


                                      -29-

         as may be requested from time to time by the Borrower and agreed to by
         the Agent; provided, however, that, after giving effect to such
         request, (a) the sum of the Dollar Equivalent of the aggregate Maximum
         Drawing Amount and all Unpaid Reimbursement Obligations shall not
         exceed $100,000,000 at any one time and (b) the sum of the Dollar
         Equivalent (i) of the Maximum Drawing Amount on all Letters of Credit,
         (ii) of all Unpaid Reimbursement Obligations, and (iii) of the amount
         of all Revolving Credit Loans outstanding shall not exceed the lesser
         of (A) the Total Commitment and (B) the Borrowing Base. Notwithstanding
         the foregoing, the Agent shall have no obligation to issue any Letter
         of Credit to support or secure any Indebtedness of the Borrower or any
         of its Subsidiaries to the extent that such Indebtedness was incurred
         prior to the proposed issuance date of such Letter of Credit, unless in
         any such case the Borrower demonstrates to the satisfaction of the
         Agent that (x) such prior incurred Indebtedness were then fully secured
         by a prior perfected and unavoidable security interest in collateral
         provided by the Borrower or such Subsidiary to the proposed beneficiary
         of such Letter of Credit or (y) such prior incurred Indebtedness were
         then secured or supported by a letter of credit issued for the account
         of the Borrower or such Subsidiary and the reimbursement obligation
         with respect to such letter of credit was fully secured by a prior
         perfected and unavoidable security interest in collateral provided to
         the issuer of such letter of credit by the Borrower or such Subsidiary.

                  5.1.2. LETTER OF CREDIT APPLICATIONS. Each Letter of Credit
         Application shall be completed to the satisfaction of the Agent. In the
         event that any provision of any Letter of Credit Application shall be
         inconsistent with any provision of this Credit Agreement, then the
         provisions of this Credit Agreement shall, to the extent of any such
         inconsistency, govern.

                  5.1.3. TERMS OF LETTERS OF CREDIT. Each Letter of Credit
         issued, extended or renewed hereunder shall, among other things, (a)
         provide for the payment of sight drafts for honor thereunder when
         presented in accordance with the terms thereof and when accompanied by
         the documents described therein, (b) have an expiry date no later than
         the date which is fourteen (14) days (or, if the Letter of Credit is
         confirmed by a confirmer or otherwise provides for one or more
         nominated persons, forty-five (45) days) prior to the Revolving Credit
         Loan Maturity Date and (c) have an expiry date no longer than one (1)
         year from the date of issuance. Each Letter of Credit so issued,
         extended or renewed shall be subject to the Uniform Customs.

                  5.1.4. REIMBURSEMENT OBLIGATIONS OF BANKS. Each Bank severally
         agrees that it shall be absolutely liable, without regard to the
         occurrence of any Default or Event of Default or any other condition
         precedent whatsoever, to the extent of such Bank's Commitment
         Percentage, to reimburse the Agent on demand for the amount of each
         draft paid by the Agent under each Letter of Credit to the extent that
         such amount is not reimbursed by the Borrower pursuant to ss.5.2 (such
         agreement for a Bank being called herein the "Letter of Credit
         Participation" of such Bank).

                  5.1.5. PARTICIPATIONS OF BANKS. Each such payment made by a
         Bank shall be treated as the purchase by such Bank of a participating
         interest in the Borrower's Reimbursement Obligation under ss.5.2 in an
         amount equal to such payment. Each 

<PAGE>   37



                                      -30-

         Bank shall share in accordance with its participating interest in any
         interest which accrues pursuant to ss.5.2.

         5.2. REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to induce the
Agent to issue, extend and renew each Letter of Credit and the Banks to
participate therein, the Borrower hereby agrees to reimburse or pay to the
Agent, for the account of the Agent or (as the case may be) the Banks, with
respect to each Letter of Credit issued, extended or renewed by the Agent
hereunder,

                  (a) except as otherwise expressly provided in ss.5.2(b) and
         (c), on each date that any draft presented under such Letter of Credit
         is honored by the Agent, or the Agent otherwise makes a payment with
         respect thereto, (i) the Dollar Equivalent of the amount paid by the
         Agent under or with respect to such Letter of Credit, and (ii) the
         Dollar Equivalent of the amount of any taxes, fees, charges or other
         costs and expenses whatsoever incurred by the Agent or any Bank in
         connection with any payment made by the Agent or any Bank under, or
         with respect to, such Letter of Credit,

                  (b) upon the reduction (but not termination) of the Total
         Commitment to an amount less than the Maximum Drawing Amount, an amount
         equal to such difference, which amount shall be held by the Agent for
         the benefit of the Banks and the Agent as cash collateral for all
         Reimbursement Obligations, and

                  (c) upon the termination of the Total Commitment, or the
         acceleration of the Reimbursement Obligations with respect to all
         Letters of Credit in accordance with ss.14, an amount equal to the
         Dollar Equivalent of then Maximum Drawing Amount on all Letters of
         Credit, which amount shall be held by the Agent for the benefit of the
         Banks and the Agent as cash collateral for all Reimbursement
         Obligations.

Each such payment shall be made to the Agent at the Agent's Head Office in
immediately available funds. Interest on any and all amounts remaining unpaid by
the Borrower under this ss.5.2 at any time from the date such amounts become due
and payable (whether as stated in this ss.5.2, by acceleration or otherwise)
until payment in full (whether before or after judgment) shall be payable to the
Agent on demand at the rate specified in ss.6.11 for overdue principal on the
Revolving Credit Loans.

         5.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented or
other demand for payment shall be made under any Letter of Credit, the Agent
shall notify the Borrower of the date and amount of the draft presented or
demand for payment and of the date and time when it expects to pay such draft or
honor such demand for payment. If the Borrower fails to reimburse the Agent as
provided in ss.5.2 on or before the date that such draft is paid or other
payment is made by the Agent, the Agent may at any time thereafter notify the
Banks of the amount of any such Unpaid Reimbursement Obligation and shall
specify such amount in Dollars (which, to the extent of any Letter of Credit
issued in an Optional Currency, is based upon the actual exchange rate at which
the Agent anticipates being able to obtain the applicable Optional Currency on
the date payment is to be made by the Banks, with any excess payment being
refunded to the Banks and any deficiency being payable by 


<PAGE>   38



                                      -31-

such Banks) required from each of the Banks. No later than 3:00 p.m. (Boston
time) on the Business Day next following the receipt of such notice, each Bank
shall make available to the Agent, at the Agent's Head Office, in immediately
available funds, such Bank's Commitment Percentage of such Unpaid Reimbursement
Obligation, together with an amount equal to the product of (a) the average,
computed for the period referred to in clause (c) below, of the weighted average
interest rate paid by the Agent for federal funds acquired by the Agent during
each day included in such period, times (b) the amount equal to such Bank's
Commitment Percentage of such Unpaid Reimbursement Obligation, times (c) a
fraction, the numerator of which is the number of days that elapse from and
including the date the Agent paid the draft presented for honor or otherwise
made payment to the date on which such Bank's Commitment Percentage of such
Unpaid Reimbursement obligation shall become immediately available to the Agent,
and the denominator of which is 360. The responsibility of the Agent to the
Borrower and the Banks shall be only to determine that the documents (including
each draft) delivered under each Letter of Credit in connection with such
presentment shall be in conformity in all material respects with such Letter of
Credit. From and after such purchase of the applicable Letter of Credit
Participation, such Unpaid Reimbursement Obligations shall be deemed to have
been converted into Base Rate Loans made by the Banks, and all amounts from time
to time accruing, and all amounts from time to time payable, on account of such
Unpaid Reimbursement Obligations shall be payable in Dollars as if such Letter
of Credit had originally been issued in Dollars.

         5.4. OBLIGATIONS ABSOLUTE. The Borrower's obligations under this ss.5
shall be absolute and unconditional under any and all circumstances and
irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Agent, any Bank or any
beneficiary of a Letter of Credit. The Borrower further agrees with the Agent
and the Banks that the Agent and the Banks shall not be responsible for, and the
Borrower's Reimbursement Obligations under ss.5.2 shall not be affected by,
among other things, the validity or genuineness of documents or of any
endorsements thereon, even if such documents should in fact prove to be in any
or all respects invalid, fraudulent or forged, or any dispute between or among
the Borrower, the beneficiary of any Letter of Credit or any financing
institution or other party to which any Letter of Credit may be transferred or
any claims or defenses whatsoever of the Borrower against the beneficiary of any
Letter of Credit or any such transferee. The Agent and the Banks shall not be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any Letter of Credit. The Borrower agrees that any action taken or omitted by
the Agent or any Bank under or in connection with each Letter of Credit and the
related drafts and documents, if done in good faith, shall be binding upon the
Borrower and shall not result in any liability on the part of the Agent or any
Bank to the Borrower.

         5.5. RELIANCE BY ISSUER. To the extent not inconsistent with ss.5.4,
the Agent shall be entitled to rely, and shall be fully protected in relying
upon, any Letter of Credit, draft, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document 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, independent accountants and
other experts selected by the Agent. The Agent shall be fully justified in
failing or refusing to take any 

<PAGE>   39





                                      -32-

action under this Agreement unless it shall first have received such advice or
concurrence of the Majority Banks as it reasonably deems appropriate or it shall
first be indemnified to its reasonable satisfaction by the Banks 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 Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement in
accordance with a request of the Majority Banks, and such request and any action
taken or failure to act pursuant thereto shall be binding upon the Banks and all
future holders of the Revolving Credit Notes or of a Letter of Credit
Participation.

         5.6. LETTER OF CREDIT FEE. The Borrower shall pay quarterly in arrears
on the last day of each calendar quarter following the issuance, extension or
renewal of any Letter of Credit and at such other time or times as such charges
are customarily made by the Agent, pay a fee (in each case, a "Letter of Credit
Fee") to the Agent in respect of each Letter of Credit issued pursuant to this
Credit Agreement, calculated at the applicable rate set forth in the definition
of Applicable Margin under the column headed "Letter of Credit Fees" per annum
on the average daily undrawn face amount of each such Letter of Credit which
shall be for the accounts of the Banks in accordance with their respective
Commitment Percentages, plus an amount equal to 1/8% per annum on the face
amount of such Letter of Credit which shall be for the account of the Agent as
an issuing fee. In respect of each Letter of Credit, the Borrower shall also pay
to the Agent for the Agent's own account, on the date of any issuance,
extension, renewal or amendment of any Letter of Credit, or at such time or
times as such charges are customarily made to the Agent; plus the Agent's
customary issuance, negotiation or document examination or other administrative
fees as in effect from time to time.

         6. CERTAIN GENERAL PROVISIONS.

         6.1. CLOSING FEE. The Borrower agrees to pay to the Agent a closing fee
in the amounts and at the times set forth in the Fee Letter.

         6.2. AGENT'S FEE. The Borrower shall pay to the Agent an agent's fee in
the amounts and at the times set forth in the Fee Letter.

         6.3. FUNDS FOR PAYMENTS.

                  6.3.1. PAYMENTS TO AGENT. All payments of principal, interest,
         Reimbursement Obligations, commitment fees, Letter of Credit Fees and
         any other amounts due hereunder or under any of the other Loan
         Documents shall be made to the Agent, for the respective accounts of
         the Banks and the Agent, at the Agent's Head Office or at such other
         location in the Boston, Massachusetts, area that the Agent may from
         time to time designate, in each case in immediately available funds.

                  6.3.2. NO OFFSET, ETC. All payments by the Borrower hereunder
         and under any of the other Loan Documents shall be made without setoff
         or counterclaim and free and clear of and without deduction for any
         taxes, levies, imposts, duties, charges, fees, deductions,
         withholdings, compulsory loans, restrictions or conditions of any
         nature now or hereafter imposed or levied by any jurisdiction or any
         political subdivision thereof or taxing or other authority therein
         unless the Borrower is 

<PAGE>   40




                                      -33-

         compelled by law to make such deduction or withholding. If any such
         obligation is imposed upon the Borrower with respect to any amount
         payable by it hereunder or under any of the other Loan Documents, the
         Borrower will pay to the Agent, for the account of the Banks or (as the
         case may be) either of the Agent, on the date on which such amount is
         due and payable hereunder or under such other Loan Document, such
         additional amount in Dollars as shall be necessary to enable the Banks
         or either of the Agent to receive the same net amount which the Banks
         or either of the Agent would have received on such due date had no such
         obligation been imposed upon the Borrower; provided, however, the
         Borrower shall have no obligations to make any such payment to any Bank
         which is organized under the laws of any jurisdiction other than the
         United States or any state thereof in respect of United States federal
         withholding taxes unless such Bank shall have delivered to the Borrower
         a duly completed and executed IRS form 1001 or 4224 that shows complete
         exemption of such Bank from such withholding tax. The Borrower will
         deliver promptly to the Agent certificates or other valid vouchers for
         all taxes or other charges deducted from or paid with respect to
         payments made by the Borrower hereunder or under such other Loan
         Document.

                  6.3.3.  CURRENCY MATTERS.

                      6.3.3.1. CURRENCY OF ACCOUNT. (a) Dollars are the currency
                  of account and payment for each and every sum at any time due
                  from the Borrower hereunder; provided that:

                           (i) each payment in respect of costs, expenses and
                  indemnities shall be made in the currency in which the same
                  were incurred; and

                           (ii) any amount expressed to be payable in a currency
                  other than Dollars shall be paid in that other currency.

                           (b) No payment to the Agent or any Bank (whether
                  under any judgment or court order or otherwise) shall
                  discharge the obligation or liability in respect of which it
                  was made unless and until the Agent or such Bank shall have
                  received payment in full in the currency in which such
                  obligation or liability was incurred, and to the extent that
                  the amount of any such payment shall, on actual conversion
                  into such currency, fall short of such obligation or liability
                  actual or contingent expressed in that currency, the Borrower
                  shall indemnify and hold harmless the Agent or such Bank, as
                  the case may be, with respect to the amount of the shortfall.

                           6.3.3.2.  CURRENCY FLUCTUATIONS.

                           (a) Not later than 1:00 p.m. (Boston time) on the
                  last Business Day of each calendar month (the "Calculation
                  Date"), the Agent shall determine the Dollar Equivalent as of
                  such date. The Dollar Equivalent so determined shall become
                  effective on the first Business Day immediately following such
                  determination (a "Reset Date") and shall remain effective
                  until the next succeeding Reset Date.

                           (b) If, on any Reset Date and on the Revolving Credit
                  Loan Maturity Date, the aggregate outstanding amount
                  (expressed in Dollars) of all Revolving Credit Loans, the sum
                  of the Maximum Drawing Amount on such date and all Unpaid
                  Reimbursement Obligations on such date, exceeds the lesser of
                  (i) Total Commitment and (ii) the Borrowing Base by more than
                  $100,000, then (i) the Agent shall give notice thereof to the
                  Borrower and the Banks and (ii) within two (2) Business Days
                  thereafter, the Borrower shall repay or prepay the Revolving
                  Credit Loans in accordance with this Credit Agreement in an
                  aggregate principal amount such that, after giving effect
                  thereto, the aggregate outstanding amount (expressed in
                  Dollars) of all Revolving Credit Loans and the sum of the
                  Maximum Drawing Amount on such date and all Unpaid
                  Reimbursement Obligations on such date, no longer exceeds the
                  lesser of (i) the Total Commitment (expressed in Dollars) and
                  (ii) the Borrowing Base.

                           (c) Without limiting subsection ss.6.3.3.2(b), if, on
                  any day prior to the Revolving Credit Loan Maturity Date, the
                  aggregate outstanding amount (expressed in Dollars) of all
                  Revolving Credit Loans and the sum of the Maximum Drawing
                  Amount on such date and all Unpaid Reimbursement Obligations
                  on such date, exceeds the lesser of (i) the Total Commitment
                  and (ii) the Borrowing Base by five percent (5%) or more, then
                  (i) the Agent shall give notice thereof to the Borrower and
                  the Banks and (ii) within two (2) Business Days thereafter,
                  the Borrower shall repay or prepay the Revolving Credit Loans
                  in accordance with this Credit Agreement in an aggregate
                  principal amount such that, after giving effect thereto, the
                  aggregate outstanding amount (expressed in Dollars) of all
                  Revolving Credit Loans and the sum of the Maximum Drawing
                  Amount on such date and all Unpaid Reimbursement Obligations
                  on such date, no longer exceeds the lesser of (i) the Total
                  Commitment (expressed in Dollars) and (ii) the Borrowing Base.
                  Nothing set forth in this ss.6.3.3.2 shall be construed to
                  require the Agent to calculate daily compliance under this
                  ss.6.3.3.2 unless expressly requested to do so by a Bank.

                           (d) If on any Reset Date, the sum of the Maximum
                  Drawing Amount on such date and all Unpaid Reimbursement
                  Obligations on such date (expressed in Dollars) exceeds the
                  Letter of Credit sublimit set forth in ss.4.1 (expressed in
                  Dollars) by more than five percent (5%), then the Borrower
                  shall immediately upon demand provide cash collateral to the
                  Agent such that, after giving effect thereto, the aggregate
                  outstanding amount of the sum of the Maximum Drawing Amount on
                  such date and all Unpaid Reimbursement Obligations on such
                  date (expressed in Dollars) no longer exceed the Letter of
                  Credit sublimit set forth in ss.4.1.

         6.4. COMPUTATIONS. All computations of interest on Base Rate Loans
shall be based on a 365-day year and paid for the actual number of days elapsed.
All computations of interest on the Eurodollar Rate Loans and of Commitment
Fees, Letter of Credit Fees or other fees shall be based on a 360-day year and
paid for the actual number of days elapsed. Except as otherwise provided in the
definition of the term "Interest Period" with respect to 
<PAGE>   42




                                      -35-

Eurodollar Rate Loans, whenever a payment hereunder or under any of the other
Loan Documents becomes due on a day that is not a Business Day, the due date for
such payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension. The outstanding amount of the Loans as
reflected on the Records from time to time shall be considered correct and
binding on the Borrower unless within five (5) Business Days after receipt of
any notice by the Agent or any of the Banks of such outstanding amount, the
Agent or such Bank shall notify the Borrower to the contrary.

         6.5. INABILITY TO DETERMINE EURODOLLAR RATE. In the event, prior to the
commencement of any Interest Period relating to any Eurodollar Rate Loan, the
Agent shall determine or be notified by the Majority Banks that adequate and
reasonable methods do not exist for ascertaining the Eurodollar Rate that would
otherwise determine the rate of interest to be applicable to any Eurodollar Rate
Loan during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks. In such event (a) any Loan Request or
Conversion Request with respect to Eurodollar Rate Loans shall be automatically
withdrawn and shall be deemed a request for Base Rate Loans, (b) each Eurodollar
Rate Loan will automatically, on the last day of the then current Interest
Period relating thereto, become a Base Rate Loan, and (c) the obligations of the
Banks to make Eurodollar Rate Loans shall be suspended until the Agent or the
Majority Banks determines that the circumstances giving rise to such suspension
no longer exist, whereupon the Agent or, as the case may be, the Agent upon the
instruction of the Majority Banks, shall so notify the Borrower and the Banks.

         6.6. ILLEGALITY. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation
or application thereof shall make it unlawful for any Bank to make or maintain
Eurodollar Rate Loans, such Bank shall forthwith give notice of such
circumstances to the Borrower and the other Banks and thereupon (a) the
commitment of such Bank to make Eurodollar Rate Loans or convert Base Rate Loans
to Eurodollar Rate Loans shall forthwith be suspended and (b) such Bank's Loans
then outstanding as Eurodollar Rate Loans, if any, shall be converted
automatically to Base Rate Loans on the last day of each Interest Period
applicable to such Eurodollar Rate Loans or within such earlier period as may be
required by law. The Borrower hereby agrees promptly to pay the Agent for the
account of such Bank, upon demand by such Bank, any additional amounts necessary
to compensate such Bank for any costs incurred by such Bank in making any
conversion in accordance with this ss.6.6, including any interest or fees
payable by such Bank to lenders of funds obtained by it in order to make or
maintain its Eurodollar Rate Loans hereunder.

         6.7. ADDITIONAL COSTS, ETC. If any present or future applicable law,
which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Bank or the Agent by any central bank or other fiscal,
monetary or other authority (whether or not having the force of law), shall:

<PAGE>   43




                                      -36-


                  (a) subject any Bank or the Agent to any tax, levy, impost,
         duty, charge, fee, deduction or withholding of any nature with respect
         to this Credit Agreement, the other Loan Documents, any Letters of
         Credit, such Bank's Commitment or the Loans (other than taxes based
         upon or measured by the income or profits of such Bank or the Agent or
         based upon any United States withholding tax for any non U.S. Bank to
         the extent such non-U.S. Bank failed to comply with ss.6.3.2), or

                  (b) materially change the basis of taxation (except for
         changes in taxes on income or profits) of payments to any Bank of the
         principal of or the interest on any Loans or any other amounts payable
         to any Bank or the Agent under this Credit Agreement or any of the
         other Loan Documents, or

                  (c) impose or increase or render applicable (other than to the
         extent specifically provided for elsewhere in this Credit Agreement)
         any special deposit, reserve, assessment, liquidity, capital adequacy
         or other similar requirements (whether or not having the force of law)
         against assets held by, or deposits in or for the account of, or loans
         by, or letters of credit issued by, or commitments of an office of any
         Bank, or

                  (d) impose on any Bank or the Agent any other conditions or
         requirements with respect to this Credit Agreement, the other Loan
         Documents, any Letters of Credit, the Loans, such Bank's Commitment, or
         any class of loans, letters of credit or commitments of which any of
         the Loans or such Bank's Commitment forms a part, and the result of any
         of the foregoing is

                           (i) to increase the cost to any Bank of making,
                  funding, issuing, renewing, extending or maintaining any of
                  the Loans or such Bank's Commitment or any Letter of Credit,
                  or

                           (ii) to reduce the amount of principal, interest,
                  Reimbursement Obligation or other amount payable to such Bank
                  or the Agent hereunder on account of such Bank's Commitment,
                  any Letter of Credit or any of the Loans, or

                           (iii) to require such Bank or the Agent to make any
                  payment or to forego any interest or Reimbursement Obligation
                  or other sum payable hereunder, the amount of which payment or
                  foregone interest or Reimbursement Obligation or other sum is
                  calculated by reference to the gross amount of any sum
                  receivable or deemed received by such Bank or the Agent from
                  the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by such Bank or
(as the case may be) the Agent at any time and from time to time and as often as
the occasion therefor may arise, pay to such Bank or the Agent such additional
amounts as will be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or foregone interest or Reimbursement
Obligation or other sum.

         6.8. CAPITAL ADEQUACY. If after the date hereof any Bank or the Agent
determines that (a) the adoption of or change in any law, governmental rule,
regulation, policy, 

<PAGE>   44




                                      -37-

guideline or directive (whether or not having the force of law) regarding
capital requirements for banks or bank holding companies or any change in the
interpretation or application thereof by a court or governmental authority with
appropriate jurisdiction, or (b) compliance by such Bank or the Agent or any
corporation controlling such Bank or the Agent with any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) of any such entity regarding capital adequacy, has the effect of reducing
the return on such Bank's or the Agent's commitment with respect to any Loans to
a level below that which such Bank or the Agent could have achieved but for such
adoption, change or compliance (taking into consideration such Bank's or the
Agent's then existing policies with respect to capital adequacy and assuming
full utilization of such entity's capital) by any amount deemed by such Bank or
(as the case may be) the Agent to be material, then such Bank or the Agent may
notify the Borrower of such fact. To the extent that the amount of such
reduction in the return on capital is not reflected in the Base Rate, the
Borrower and such Bank shall thereafter attempt to negotiate in good faith,
within thirty (30) days of the day on which the Borrower receives such notice,
an adjustment payable hereunder that will adequately compensate such Bank in
light of these circumstances. If the Borrower and such Bank are unable to agree
to such adjustment within thirty (30) days of the date on which the Borrower
receives such notice, then commencing on the date of such notice (but not
earlier than the effective date of any such increased capital requirement), the
fees payable hereunder shall increase by an amount that will, in such Bank's
reasonable determination, provide adequate compensation. Each Bank shall
allocate such cost increases among its customers in good faith and on an
equitable basis.

         6.9. CERTIFICATE. A certificate setting forth any additional amounts
payable pursuant to ss.ss.6.7 or 6.8 and a brief explanation of such amounts
which are due, submitted by any Bank or the Agent to the Borrower, shall be
conclusive, absent manifest error, that such amounts are due and owing.

         6.10. INDEMNITY. The Borrower agrees to indemnify each Bank and to hold
each Bank harmless from and against any loss, cost or expense (excluding loss of
anticipated profits) that such Bank may sustain or incur as a consequence of (a)
default by the Borrower in payment of the principal amount of or any interest on
any Eurodollar Rate Loans as and when due and payable, including any such loss
or expense arising from interest or fees payable by such Bank to lenders of
funds obtained by it in order to maintain its Eurodollar Rate Loans, (b) default
by the Borrower in making a borrowing or conversion after the Borrower has given
(or is deemed to have given) a Loan Request, notice (in the case of all or any
portion of the Term Loan pursuant to ss.4.5.2) or a Conversion Request relating
thereto in accordance with ss.2.6, ss.2.7 or ss.4.5 or (c) the making of any
payment of a Eurodollar Rate Loan or the making of any conversion of any such
Eurodollar Rate Loan to a Base Rate Loan on a day that is not the last day of
the applicable Interest Period with respect thereto, including interest or fees
payable by such Bank to lenders of funds obtained by it in order to maintain any
such Eurodollar Rate Loans.

         6.11. INTEREST AFTER DEFAULT.

                  6.11.1. OVERDUE AMOUNTS. Overdue principal and (to the extent
         permitted by applicable law) interest on the Loans and all other
         overdue amounts payable 

<PAGE>   45



                                      -38-


         hereunder or under any of the other Loan Documents shall bear interest
         compounded monthly and payable on demand at a rate per annum equal to
         two percent (2%) above the Base Rate until such amount shall be paid in
         full (after as well as before judgment).

                  6.11.2. AMOUNTS NOT OVERDUE. During the continuance of a
         Default or an Event of Default the principal of the Loans not overdue
         shall, until such Default or Event of Default has been cured or
         remedied or such Default or Event of Default has been waived by the
         Majority Banks pursuant to ss.27, bear interest at a rate per annum
         equal to the greater of (a) four percent (4%) above the rate of
         interest otherwise applicable to such Revolving Credit Loans pursuant

hereto, the Borrower and its Subsidiaries own all of the assets reflected in the
consolidated balance sheet of the Borrower and its Subsidiaries as at the
Balance Sheet Date or acquired since that date (except property and assets sold
or otherwise disposed of in the ordinary course of business since that date),
subject to no rights of others, including any mortgages, leases, conditional
sales agreements, title retention agreements, liens or other encumbrances except
Permitted Liens.

         8.4. FINANCIAL STATEMENTS AND PROJECTIONS.

                  8.4.1. FINANCIAL STATEMENTS. The Borrower and each of its
         Subsidiaries has a fiscal year which is the twelve months ending on the
         last Saturday of every June of each calendar year.

                  8.4.2. FINANCIAL STATEMENTS. There has been furnished to each
         of the Banks a consolidated balance sheet and statement of cash flow of
         the Borrower and 

<PAGE>   47



                                      -40-


         its Subsidiaries as at the Balance Sheet Date, and a consolidated
         statement of income of the Borrower and its Subsidiaries for the fiscal
         year then ended, certified by KPMG Peat Marwick. Such balance sheet and
         statement of income have been prepared in accordance with generally
         accepted accounting principles and fairly present the financial
         condition of the Borrower as at the close of business on the date
         thereof and the results of operations for the fiscal year then ended.
         There are no contingent liabilities of the Borrower or any of its
         Subsidiaries as of such date involving material amounts, known to the
         officers of the Borrower, which were not disclosed in such balance
         sheet and the notes related thereto.

                  8.4.3. PROJECTIONS. The projections of the annual operating
         budgets of the Borrower and its Subsidiaries on a consolidated basis,
         balance sheets and cash flow statements for the 1998 to 1999 fiscal
         years, copies of which have been delivered to each Bank, disclose all
         assumptions made with respect to general economic, financial and market
         conditions used in formulating such projections. To the knowledge of
         the Borrower or any of its Subsidiaries, no facts exist that
         (individually or in the aggregate) would result in any material change
         in any of such projections or to the cash flow statements delivered to
         the Banks. The projections are based upon reasonable estimates and
         assumptions, have been prepared on the basis of the assumptions stated
         therein and reflect the reasonable estimates of the Borrower and its
         Subsidiaries of the results of operations and other information
         projected therein.

         8.5. NO MATERIAL CHANGES, ETC. Since December 27, 1997 there has
occurred no materially adverse change in the financial condition or business of
the Borrower and its Subsidiaries as shown on or reflected in the consolidated
balance sheet of the Borrower and its Subsidiaries as at December 27, 1997, or
the consolidated statement of income for the fiscal year then ended, other than
changes in the ordinary course of business that have not had any materially
adverse effect either individually or in the aggregate on the business or
financial condition of the Borrower or any of its Subsidiaries. Since December
27, 1997, neither the Borrower nor any of its Subsidiaries has made any
Distributions which are prohibited by ss.10.4 hereof.

         8.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. Each of the Borrower and its
Subsidiaries possesses all franchises, patents, copyrights, trademarks, trade
names, licenses and permits, and rights in respect of the foregoing, adequate
for the conduct of its business substantially as now conducted without known
conflict with any rights of others where such conflict could reasonably be
expected to have a materially adverse effect on the business, assets or
financial condition of the Borrower or any of its Subsidiaries.

         8.7. LITIGATION. Except as set forth in Schedule 8.7 hereto, there are
no actions, suits, proceedings or investigations of any kind pending against the
Borrower or any of its Subsidiaries before any court, tribunal or administrative
agency or board that, if adversely determined, might, either in any case or in
the aggregate, materially adversely affect the properties, assets, financial
condition or business of the Borrower and its Subsidiaries or materially impair
the right of the Borrower and its Subsidiaries, considered as a whole, to carry
on business substantially as now conducted by them, or result in any substantial
liability not adequately covered by insurance, or for which adequate reserves
are not

                                      -41-

maintained on the consolidated balance sheet of the Borrower and its
Subsidiaries, or which question the validity of this Credit Agreement or any of
the other Loan Documents, or any action taken or to be taken pursuant hereto or
thereto.

         8.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the Borrower nor any
of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation that has or is
expected in the future to have a materially adverse effect on the business,
assets or financial condition of the Borrower or any of its Subsidiaries.
Neither the Borrower nor any of its Subsidiaries is a party to any contract or
agreement that has or is expected, in the judgment of the Borrower's officers,
to have any materially adverse effect on the business of the Borrower or any of
its Subsidiaries.

         8.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the Borrower
nor any of its Subsidiaries is in violation of any provision of its charter
documents, bylaws, or any agreement or instrument to which it may be subject or
by which it or any of its properties may be bound or any decree, order,
judgment, statute, license, rule or regulation, in any of the foregoing cases in
a manner that could result in the imposition of substantial penalties or
materially and adversely affect the financial condition, properties or business
of the Borrower or any of its Subsidiaries.

         8.10. TAX STATUS. The Borrower and its Subsidiaries (a) have made or
filed all federal and state income and all other tax returns, reports and
declarations required by any jurisdiction to which any of them is subject, (b)
have paid all taxes and other governmental assessments and charges shown or
determined to be due on such returns, reports and declarations, except those
being contested in good faith and by appropriate proceedings and (c) have set
aside on their books provisions reasonably adequate for the payment of all taxes
for periods subsequent to the periods to which such returns, reports or
declarations apply. There are no unpaid taxes in any material amount claimed to
be due by the taxing authority of any jurisdiction, and the officers of the
Borrower know of no basis for any such claim.

         8.11. NO EVENT OF DEFAULT. No Default or Event of Default has occurred
and is continuing.

         8.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the Borrower
nor any of its Subsidiaries is a "holding company", or a "subsidiary company" of
a "holding company", or an "affiliate" of a "holding company", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is it an
"investment company", or an "affiliated company" or a "principal underwriter" of
an "investment company", as such terms are defined in the Investment Company Act
of 1940.

         8.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except with respect to
Permitted Liens, there is no financing statement, security agreement, chattel
mortgage, real estate mortgage or other document filed or recorded with any
filing records, registry or other public office, that purports to cover, affect
or give notice of any present or possible future lien on, or security interest
in, any assets or property of the Borrower or any of its Subsidiaries or any
rights relating thereto.

<PAGE>   49





                                      -42-

         8.14. PERFECTION OF SECURITY INTEREST. All filings, assignments,
pledges and deposits of documents or instruments have been made and all other
actions have been taken that are necessary or advisable, under applicable law,
to establish and perfect the Agent's security interest in the Collateral. The
Collateral and the Agent's rights with respect to the Collateral are not subject
to any setoff, claims, withholdings or other defenses which could reasonably be
expected to have a material adverse effect on the business, assets or financial
condition of the Borrower or the Borrower and its Subsidiaries, taken as a
whole, or the Agent's rights with respect to the Collateral. The Borrower or a
Subsidiary of the Borrower which is a party to one of the Security Agreements is
the owner of the Collateral free from any lien, security interest, encumbrance
and any other claim or demand, except for Permitted Liens.

         8.15. CERTAIN TRANSACTIONS. Except as set forth on Schedule 8.15 hereto
and except for arm's length transactions pursuant to which the Borrower or any
of its Subsidiaries makes payments in the ordinary course of business upon terms
no less favorable than the Borrower or such Subsidiary could obtain from third
parties or which could otherwise have a material adverse effect on the business,
assets or financial condition of the Borrower or any of its Subsidiaries, none
of the officers, directors, or employees of the Borrower or any of its
Subsidiaries is presently a party to any transaction with the Borrower or any of
its Subsidiaries (other than for services as employees, officers and directors),
including any contract, agreement or other arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Borrower, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

         8.16. EMPLOYEE BENEFIT PLANS.

                  8.16.1. IN GENERAL. Each Employee Benefit Plan and each
         Guaranteed Pension Plan has been maintained and operated in compliance
         in all material respects with the provisions of ERISA and, to the
         extent applicable, the Code, including but not limited to the
         provisions thereunder respecting prohibited transactions and the
         bonding of fiduciaries and other persons handling plan funds as
         required by ss.412 of ERISA. The Borrower has heretofore delivered to
         the Agent the most recently completed annual report, Form 5500, with
         all required attachments, and actuarial statement required to be
         submitted under ss.103(d) of ERISA, with respect to each Guaranteed
         Pension Plan.

                  8.16.2. TERMINABILITY OF WELFARE PLANS. No Employee Benefit
         Plan, which is an employee welfare benefit plan within the meaning of
         ss.3(1) or ss.3(2)(B) of ERISA, provides benefit coverage subsequent to
         termination of employment, except as required by Title I, Part 6 of
         ERISA or the applicable state insurance laws. The Borrower may
         terminate each such Plan at any time (or at any time subsequent to the
         expiration of any applicable bargaining agreement) in the discretion of
         the Borrower without liability to any Person other than for claims
         arising prior to termination.

<PAGE>   50


                                      -43-

                  8.16.3. GUARANTEED PENSION PLANS. Each contribution required
         to be made to a Guaranteed Pension Plan, whether required to be made to
         avoid the incurrence of an accumulated funding deficiency, the notice
         or lien provisions of ss.302(f) of ERISA, or otherwise, has been timely
         made. No waiver of an accumulated funding deficiency or extension of
         amortization periods has been received with respect to any Guaranteed
         Pension Plan, and neither the Borrower nor any ERISA Affiliate is
         obligated to or has posted security in connection with an amendment to
         a Guaranteed Pension Plan pursuant to ss.307 of ERISA or ss.401(a)(29)
         of the Code. No liability to the PBGC (other than required insurance
         premiums, all of which have been paid) has been incurred by the
         Borrower or any ERISA Affiliate with respect to any Guaranteed Pension
         Plan and there has not been any ERISA Reportable Event (other than an
         ERISA Reportable Event as to which the requirement of 30 days notice
         has been waived), or any other event or condition which presents a
         material risk of termination of any Guaranteed Pension Plan by the
         PBGC. Based on the latest valuation of each Guaranteed Pension Plan
         (which in each case occurred within twelve months of the date of this
         representation), and on the actuarial methods and assumptions employed
         for that valuation, the aggregate benefit liabilities of all such
         Guaranteed Pension Plans within the meaning of ss.4001 of ERISA did not
         exceed the aggregate value of the assets of all such Guaranteed Pension
         Plans, disregarding for this purpose the benefit liabilities and assets
         of any Guaranteed Pension Plan with assets in excess of benefit
         liabilities.

                  8.16.4. MULTIEMPLOYER PLANS. Neither the Borrower nor any
         ERISA Affiliate has incurred any material liability (including
         secondary liability) to any Multiemployer Plan as a result of a
         complete or partial withdrawal from such Multiemployer Plan under
         ss.4201 of ERISA or as a result of a sale of assets described in
         ss.4204 of ERISA. Neither the Borrower nor any ERISA Affiliate has been
         notified that any Multiemployer Plan is in reorganization or insolvent
         under and within the meaning of ss.4241 or ss.4245 of ERISA or is at
         risk of entering reorganization or becoming insolvent, or that any
         Multiemployer Plan intends to terminate or has been terminated under
         ss.4041A of ERISA.

         8.17. USE OF PROCEEDS.

                  8.17.1. GENERAL. The proceeds of the Loans shall be used (a)
         to refinance existing Indebtedness of the Borrower and (b) for working
         capital and general corporate purposes. The Borrower will obtain
         Letters of Credit solely for working capital and general corporate
         purposes.

                  8.17.2. REGULATIONS U AND X. No portion of any Loan is to be
         used, and no portion of any Letter of Credit is to be obtained, for the
         purpose of purchasing or carrying any "margin security" or "margin
         stock" as such terms are used in Regulations U and X of the Board of
         Governors of the Federal Reserve System, 12 C.F.R. Parts 221 and 224.

                  8.17.3. INELIGIBLE SECURITIES. No portion of the proceeds of
         any Loans is to be used, and no portion of any Letter of Credit is to
         be obtained, for the purpose of (a) knowingly purchasing, or providing
         credit support for the purchase of, Ineligible 

<PAGE>   51



                                      -44-


         Securities from a Section 20 Subsidiary during any period in which such
         Section 20 Subsidiary makes a market in such Ineligible Securities, (b)
         knowingly purchasing, or providing credit support for the purchase of,
         during the underwriting or placement period, any Ineligible Securities
         being underwritten or privately placed by a Section 20 Subsidiary, or
         (c) making, or providing credit support for the making of, payments of
         principal or interest on Ineligible Securities underwritten or
         privately placed by a Section 20 Subsidiary and issued by or for the
         benefit of the Borrower or any Subsidiary or other Affiliate of the
         Borrower.

         8.18. ENVIRONMENTAL COMPLIANCE. To the best of the Borrower's
knowledge, based upon a reasonable investigation, the Borrower has determined
that:

                  (a) none of the Borrower, its Subsidiaries or any operator of
         the Real Estate located in the United States or any operations thereon
         is in violation, or alleged violation, of any judgment, decree, order,
         law, license, rule or regulation pertaining to environmental matters,
         including without limitation, those arising under the Resource
         Conservation and Recovery Act ("RCRA"), the Comprehensive Environmental
         Response, Compensation and Liability Act of 1980 as amended ("CERCLA"),
         the Superfund Amendments and Reauthorization Act of 1986 ("SARA"), the
         Federal Clean Water Act, the Federal Clean Air Act, the Toxic
         Substances Control Act, or any state or local statute, regulation,
         ordinance, order or decree relating to health, safety or the
         environment (hereinafter "Environmental Laws"), which violation would
         have a material adverse effect on the environment or the business,
         assets or financial condition of the Borrower or any of its
         Subsidiaries;

                  (b) neither the Borrower nor any of its Subsidiaries has
         received notice from any third party including, without limitation, any
         federal, state or local governmental authority, (i) that any one of
         them has been identified by the United States Environmental Protection
         Agency ("EPA") as a potentially responsible party under CERCLA with
         respect to a site listed on the National Priorities List, 40 C.F.R.
         Part 300 Appendix B; (ii) that any hazardous waste, as defined by 42
         U.S.C. ss.6903(5), any hazardous substances as defined by 42 U.S.C.

         ss.9601(33) and any toxic substances, oil or hazardous materials or
         other chemicals or substances regulated by any Environmental Laws
         ("Hazardous Substances") which any one of them has generated,
         transported or disposed of has been found at any site at which a
         federal, state or local agency or other third party has conducted or
         has ordered that any Borrower or any of its Subsidiaries conduct a
         remedial investigation, removal or other response action pursuant to
         any Environmental Law; or (iii) except to the extent that the following
         would not have a material adverse effect on the business, assets or
         financial condition of the Borrower or any of its Subsidiaries, that it
         is or shall be a named party to any claim, action, cause of action,
         complaint, or legal or administrative proceeding (in each case,
         contingent or otherwise) arising out of any third party's incurrence of
         costs, expenses, losses or damages of any kind whatsoever in connection
         with the release of Hazardous Substances;

                  (c) except as set forth on Schedule 8.18 attached hereto: (i)
         no portion of the Real Estate located in the United States has been

         material adverse effect on the business, assets or financial condition
         of the Borrower and its Subsidiaries; (ii) in the course of any
         activities conducted by the Borrower, its Subsidiaries or operators of

         material adverse effect on the value of, the Real Estate located in the
         United States; and (v) in addition, except to the extent that the
         following would not have a materially adverse effect on the business,

         and applicable Environmental Laws; and

                  (d) None of the Borrower and its Subsidiaries or any of the

         site assessments, or the removal or remediation of Hazardous
         Substances, or the giving of notice to any governmental agency or the
         recording or delivery to other Persons of an environmental disclosure

         8.21. DISCLOSURE. None of this Credit Agreement or any of the other
Loan Documents contains any untrue statement of a material fact or omits to
state a material fact (known to the Borrower or any of its Subsidiaries in the
case of any document or information not furnished by it or any of its
Subsidiaries) necessary in order to make the statements herein or therein not
misleading. There is no fact known to the Borrower or any of its Subsidiaries
which materially adversely affects, or which is reasonably likely in the future

         8.23. STATUS OF LOAN AS SENIOR DEBT. From and after such time as the

Indebtedness" or "Senior Debt" (or the analogous term used therein) under the

pursuant to which there is issued Indebtedness which purports to be Subordinated
Debt of the Borrower or any Subsidiary.

         8.24. NO OTHER DESIGNATED SENIOR DEBT. From and after such time as the
Borrower has incurred or assumed any Subordinated Debt, the Borrower has not
designated any Indebtedness of the Borrower or any of its Subsidiaries as, and
has no, "Designated Senior Debt" (or the analogous term used therein) for
purposes of (and as defined in) the Subordinated Indenture, other than the
Obligations.

                    9. AFFIRMATIVE COVENANTS OF THE BORROWER.

Reimbursement Obligation, Letter of Credit or Note is outstanding or any Bank
has any obligation to make any Loans or the Agent has any obligation to issue,
extend or renew any Letters of Credit:

         9.1. PUNCTUAL PAYMENT. The Borrower will duly and punctually pay or
cause to be paid the principal and interest on the Loans, all Reimbursement

         9.3. RECORDS AND ACCOUNTS. The Borrower will (a) keep, and cause each

accepted accounting principles; (b) maintain adequate accounts and reserves for
all taxes (including income taxes), depreciation, depletion, obsolescence and

         accountants shall have obtained knowledge of any then existing Default
         or Event of Default they shall disclose in such statement any such
         Default or Event of Default; provided that such accountants shall not
         be liable to the Banks for failure to obtain knowledge of any Default

         Borrower in substantially the form of Exhibit E hereto (the "Compliance

         applicable) reconciliations to reflect changes in generally accepted
         accounting principles since the Balance Sheet Date;

be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times, and (c) will, and will cause
each of its Subsidiaries to, continue to engage primarily in the businesses now
conducted by them and in related businesses; provided that nothing in this
ss.9.6 shall prevent the Borrower from discontinuing the operation and
maintenance of any of its properties or any of those of its Subsidiaries if such
discontinuance is, in the judgment of the Borrower, desirable in the conduct of
its or their business and that do not in the

labor, materials, or supplies that if unpaid might by law become a lien or
charge upon any of its property; provided that any such tax, assessment, charge,
levy or claim need not be paid if the validity or amount thereof shall currently
be contested in good faith by appropriate proceedings and if the Borrower or
such Subsidiary shall have set aside on its books adequate reserves with respect
thereto; and provided further that the Borrower and each Subsidiary of the
Borrower will pay all such taxes, assessments, charges, levies or claims
forthwith upon the commencement of proceedings to foreclose any lien that may
have attached as security therefor.

         9.9. INSPECTION OF PROPERTIES AND BOOKS, ETC.

                  9.9.1. GENERAL. The Borrower shall permit the Banks, through
         the Agent or any of the Banks' other designated representatives, to
         visit and inspect any of the properties of the Borrower or any of its

         officers, all at such reasonable times and intervals as the Agent or
         any Bank may reasonably request.

                  9.9.2. COLLATERAL REPORTS. No more frequently than once during
         each calendar year, or more frequently as determined by the Agent if an
         Event of Default shall have occurred and be continuing, upon the

         Agent, or, if the Agent so elects, will cooperate with the Agent in the
         Agent's obtaining, (a) a report of an independent collateral auditor
         satisfactory to the Agent (which may be affiliated with one of the
         Banks) with respect to the Accounts Receivable component included in
         the Borrowing Base, which report shall indicate whether or not the
         information set forth in the Borrowing Base Report most recently
         delivered is accurate and complete in all material respects based upon
         a review by such auditors of the Accounts Receivable (including
         verification with respect to the amount, aging, identity and credit of
         the respective account debtors and the billing practices of the
         Borrower or its applicable Subsidiary) and (b) appraisal reports in
         form and substance and from appraisers satisfactory to the Agent,

         real estate owned by the Borrower or any of its Subsidiaries and (ii)
         the then current business value of each of the Borrower and its
         Subsidiaries. All such appraisals and collateral value reports shall be
         conducted and made at the expense of the Borrower. In addition, no more
         frequently than once each calendar year, or more frequently as
         determined by the Agent if an Event of Default shall have occurred and
         be continuing, the Agent shall be entitled to conduct a commercial
         finance examination of the Borrower at its Subsidiaries, such
         commercial finance examinations to be at the Borrower's expense.

                  9.9.3. COMMUNICATIONS WITH ACCOUNTANTS. The Borrower
         authorizes the Agent and, if accompanied by the Agent, the Banks to

         and the Banks any and all financial statements and other supporting
         financial documents and schedules including copies of any management
         letter with respect to the business, financial condition and other
         affairs of the Borrower or any of its Subsidiaries. At the request of

         ss.9.9.3

         9.10. COMPLIANCE WITH LAWS, CONTRACTS, LICENSES, AND PERMITS. The
Borrower will, and will cause each of its Subsidiaries to, comply with (a) the
applicable laws and regulations wherever its business is conducted, including
all Environmental Laws, unless the failure to so comply would not have a
material adverse effect on the business, assets or financial condition of the
Borrower or such Subsidiary, (b) the provisions of its charter documents and
by-laws, (c) all agreements and instruments by which it or any of its properties
may be bound, unless the failure to so comply would not have a material adverse
effect on the business, assets or financial condition of the Borrower or such
Subsidiary and (d) all applicable decrees, orders, and judgments, unless the
failure to so comply would not have a material adverse effect on the business,
assets or financial condition of the Borrower or such Subsidiary. If any
authorization, consent, approval, permit or license from any officer, agency or
instrumentality of any government shall become necessary or required in order
that the Borrower or any of its Subsidiaries may fulfill any of its obligations
hereunder or any of the other Loan Documents to which the Borrower or such
Subsidiary is a party, the Borrower will, or (as the case may be) will cause
such Subsidiary to, immediately take or cause to be taken all reasonable steps

authorization, consent, approval, permit or license and furnish the Agent and
the Banks with evidence thereof.

the repurchase by the Borrower of its capital stock). The Borrower will obtain
Letters of Credit solely for working capital and general corporate purposes.

         9.13. GUARANTORS. The Borrower will cause each Domestic Subsidiary
created, acquired or existing on or after the Closing Date, or any other
Subsidiary which is otherwise required to become a guarantor under any
Subordinated Debt Document, to become a Guarantor immediately and shall cause
such Subsidiary to execute and deliver to the Agent for the benefit of the Agent
and the Banks (a) a Guaranty (or an Instrument of Adherence to the Guaranty
executed on the Closing Date), and (b) further Security Documents or other
instruments and documents as the Agent may reasonably require in order to grant
to the Agent a first priority perfected security interest in such Subsidiary's
assets, together with legal opinions in form and substance reasonably
satisfactory to the Agent to be delivered to the Agent and the Banks opining as
to the authorization, validity and enforceability of such Guaranty or Instrument
of Adherence and Security Documents and (as to the applicable Security
Documents) the perfection of such security interests.

         9.14. ADDITIONAL SUBSIDIARIES. If, after the Closing Date, the Borrower
or any of its Subsidiaries creates or acquires, either directly or indirectly,
any Subsidiary, it will immediately notify the Agent and the Banks if such
creation or acquisition, as the case may be, and provide the Agent and the Banks
with an updated Schedule 8.19(a) hereof and take all other actions required by
ss.9.13 and ss.10.5.1 hereof.

         9.15. SUBORDINATED GUARANTEES. From and after the time the Borrower has
incurred or assumed any Subordinated Debt, the Borrower will promptly advise the
Agent of any guarantee entered into in connection with any provision of the
Subordinated Indenture or similar agreement requiring any Subsidiary guarantees,
and identifying the guarantor thereunder.

         9.16. STATUS OF LOAN AS SENIOR DEBT. The Borrower shall, on the date
the Subordinated Indenture becomes effective and the Subordinated Notes are
issued, and at such other times as may reasonably be requested by the Agent,
deliver to the Agent certificates and, if requested, legal opinions, evidencing
that the Indebtedness of the Borrower and its Subsidiaries to the Banks and the
Agent in respect of the Loans and Reimbursement Obligations constitute "Superior
Indebtedness", "Senior Indebtedness" or "Senior Debt" (or the analogous terms

         repurchase or redeem) by the Borrower or any of its Subsidiaries of the
         Subordinated Notes or any other Subordinated Debt pursuant to the

                  (i) there shall remain in force, undischarged, unsatisfied and
         unstayed, for more than thirty days, whether or not consecutive, any

         to the PBGC or a Guaranteed Pension Plan pursuant to Title IV of ERISA
         in an aggregate amount exceeding $2,000,000 or the Borrower or any

                  (l) the Borrower or any of its Subsidiaries shall be enjoined,
         restrained or in any way prevented by the order of any court or any
         administrative or regulatory agency from conducting any material part
         of its business and such order shall continue in effect for more than
         thirty (30) days;

                  (m) there shall occur any material damage to, or loss, theft

         consecutive days, the cessation or substantial curtailment of revenue
         producing activities of the Borrower or any of its Subsidiaries if such
         event or circumstance is not covered by business interruption insurance

                                      -69-

         Subsidiary not included in the Borrowing Base but having a fair market
         value in excess of $5,000,000;

                  (p) the holders of all or any part of the Subordinated Debt
         shall accelerate the maturity of all or any part of the Subordinated
         Debt or the Subordinated Debt shall be (or shall be required at such
         time to be) prepaid, redeemed or repurchased in whole or in part; or
         the Borrower shall be or become required under the Subordinated

         any part of the Subordinated Debt;

                  (q) a "Change of Control" (or any analogous term used therein)
         as such term is defined in the Subordinated Indenture or any similar
         agreement governing any other Subordinated Debt occurs;

                  (r) the Borrower shall at any time fail legally or
         beneficially own less than 100% of the capital stock of any of the
         Guarantors; or

                  (s) any Person shall at any time be the legal or beneficial
         owner (within the meaning used in Rule 13d-3 of the Securities and
         Exchange Commission promulgated under the Securities Exchange Act of
         1934, as amended) of more than fifty percent (50%) of the outstanding
         shares of the common stock of the Borrower;

then, and in any such event, so long as the same may be continuing, the Agent
may, and upon the request of the Majority Banks shall, by notice in writing to
the Borrower declare all amounts owing with respect to this Credit Agreement,
the Notes and the other Loan Documents and all Reimbursement Obligations to be,
and they shall thereupon forthwith become, immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived by the Borrower; provided that in the event of any Event
of Default specified in ss.ss.14.1(g) or 14.1(h), all such amounts shall become
immediately due and payable automatically and without any requirement of notice
from the Agent or any Bank.

         14.2. TERMINATION OF COMMITMENTS. If any one or more of the Events of
Default specified in ss.14.1(g) or ss.14.1(h) shall occur, any unused portion of
the credit hereunder shall forthwith terminate and each of the Banks shall be
relieved of all further obligations to make Loans to the Borrower and the Agent
shall be relieved of all further obligations to issue, extend or renew Letters
of Credit. If any other Event of Default shall have occurred and be continuing,
or if on any Drawdown Date or other date for issuing, extending or renewing any
Letter of Credit the conditions precedent to the making of the Loans to be made
on such Drawdown Date or (as the case may be) to issuing, extending or renewing
such Letter of Credit on such other date are not satisfied, the Agent may and,
upon the request of the Majority Banks, shall, by notice to the Borrower,
terminate the unused portion of the credit hereunder, and upon such notice being
given such unused portion of the credit hereunder shall terminate immediately
and each of the Banks shall be relieved of all further obligations to make Loans
and the Agent shall be relieved of all further obligations to issue, extend or
renew Letters of Credit. No termination of the credit hereunder shall relieve
the Borrower or any of its Subsidiaries of any of the Obligations.

                                      -70-

         14.3. REMEDIES. In case any one or more of the Events of Default shall
have occurred and be continuing, and whether or not the Banks shall have
accelerated the maturity of the Loans pursuant to ss.14.1, each Bank, if owed
any amount with respect to the Loans or the Reimbursement Obligations, may, with
the consent of the Majority Banks but not otherwise, proceed to protect and
enforce its rights by suit in equity, action at law or other appropriate
proceeding, whether for the specific performance of any covenant or agreement
contained in this Credit Agreement and the other Loan Documents or any
instrument pursuant to which the Obligations to such Bank are evidenced,
including as permitted by applicable law the obtaining of the ex parte
appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Bank. No remedy herein conferred upon any Bank
or the Agent or the holder of any Note or purchaser of any Letter of Credit
Participation is intended to be exclusive of any other remedy and each and every
remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or any
other provision of law.

         14.4. DISTRIBUTION OF COLLATERAL PROCEEDS. In the event that, following
the occurrence or during the continuance of any Default or Event of Default, the
Agent, any Bank or the Bank Guarantee Bank, as the case may be, receives any
monies in connection with the enforcement of any of the Security Documents, or
otherwise with respect to the realization upon any of the Collateral, such
monies shall be distributed for application as follows:

                  (a) First, to the payment of, or (as the case may be) the
         reimbursement of the Agent for or in respect of all reasonable costs,
         expenses, disbursements and losses which shall have been incurred or
         sustained by the Agent in connection with the collection of such monies
         by the Agent, for the exercise, protection or enforcement by the Agent
         of all or any of the rights, remedies, powers and privileges of the
         Agent under this Credit Agreement or any of the other Loan Documents or
         in respect of the Collateral or in support of any provision of adequate
         indemnity to the Agent against any taxes or liens which by law shall
         have, or may have, priority over the rights of the Agent to such
         monies;

                  (b) Second, to all other Obligations in such order or
         preference as the Majority Banks may determine; provided, however, that
         (i) distributions shall be made (A) pari passu among Obligations with
         respect to the Agent's fee payable pursuant to ss.6.2, the Obligations
         owing to the Bank Guarantee Bank pursuant to the Credit Instruments and
         all other Obligations; and (B) with respect to each type of Obligation
         owing to the Banks and the Bank Guarantee Bank, such as interest,
         principal, fees and expenses, among the Banks and the Bank Guarantee
         Bank pro rata, and (ii) the Agent may in its discretion make proper
         allowance to take into account any Obligations not then due and
         payable;

                  (c) Third, upon payment and satisfaction in full or other
         provisions for payment in full satisfactory to the Banks, the Bank
         Guarantee Bank and the Agent of all of the Obligations, to the payment
         of any obligations required to be paid pursuant to ss.9-504(1)(c) of
         the Uniform Commercial Code of the Commonwealth of Massachusetts; and

<PAGE>   78


                                      -71-

                  (d) Fourth, the excess, if any, shall be returned to the
         Borrower or to such other Persons as are entitled thereto.

                                   15. SETOFF.

         Regardless of the adequacy of any collateral, during the continuance of
any Event of Default, any deposits or other sums credited by or due from any of
the Banks to the Borrower and any securities or other property of the Borrower
in the possession of such Bank may be applied to or set off by such Bank against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Bank. Each of the Banks agrees with
each other Bank that (a) if an amount to be set off is to be applied to
Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced by
the Notes held by such Bank or constituting Reimbursement Obligations owed to
such Bank, such amount shall be applied ratably to such other Indebtedness and
to the Indebtedness evidenced by all such Notes held by such Bank or
constituting Reimbursement Obligations owed to such Bank, and (b) if such Bank
shall receive from the Borrower, whether by voluntary payment, exercise of the
right of setoff, counterclaim, cross action, enforcement of the claim evidenced
by the Notes held by, or constituting Reimbursement Obligations owed to, such
Bank by proceedings against the Borrower at law or in equity or by proof thereof
in bankruptcy, reorganization, liquidation, receivership or similar proceedings,
or otherwise, and shall retain and apply to the payment of the Note or Notes
held by, or Reimbursement Obligations owed to, such Bank any amount in excess of
its ratable portion of the payments received by all of the Banks with respect to
the Notes held by, and Reimbursement Obligations owed to, all of the Banks, such
Bank will make such disposition and arrangements with the other Banks with
respect to such excess, either by way of distribution, pro tanto assignment of
claims, subrogation or otherwise as shall result in each Bank receiving in
respect of the Notes held by it or Reimbursement obligations owed it, its
proportionate payment as contemplated by this Credit Agreement; provided that if
all or any part of such excess payment is thereafter recovered from such Bank,
such disposition and arrangements shall be rescinded and the amount restored to
the extent of such recovery, but without interest.

                                 16. THE AGENT.

         16.1.  AUTHORIZATION.

                  (a) The Agent is authorized to take such action on behalf of
         each of the Banks and to exercise all such powers as are hereunder and
         under any of the other Loan Documents and any related documents
         delegated to the Agent, together with such powers as are reasonably
         incident thereto, provided that no duties or responsibilities not
         expressly assumed herein or therein shall be implied to have been
         assumed by the Agent.

                  (b) The relationship between the Agent and each of the Banks
         is that of an independent contractor. The use of the term "Agent" is
         for convenience only and is used to describe, as a form of convention,
         the independent contractual relationship between the Agent and each of
         the Banks. Nothing contained in this Credit 

<PAGE>   79




                                      -72-


         Agreement nor the other Loan Documents shall be construed to create an 
         agency, trust or other fiduciary relationship between any of the Agent 
         and any of the Banks.

                  (c) As an independent contractor empowered by the Banks to
         exercise certain rights and perform certain duties and responsibilities
         hereunder and under the other Loan Documents, the Agent is nevertheless
         a "representative" of the Banks, as that term is defined in Article 1
         of the Uniform Commercial Code, for purposes of actions for the benefit
         of the Banks and the Agent with respect to all collateral security and
         guaranties contemplated by the Loan Documents. Such actions include the
         designation of the Agent as "secured party", "mortgagee" or the like on
         all financing statements and other documents and instruments, whether
         recorded or otherwise, relating to the attachment, perfection, priority
         or enforcement of any security interests, mortgages or deeds of trust
         in collateral security intended to secure the payment or performance of
         any of the Obligations, all for the benefit of the Banks and the Agent.

         16.2. EMPLOYEES AND AGENTS. The Agent may exercise its powers and
execute its duties by or through employees or agents and shall be entitled to
take, and to rely on, advice of counsel concerning all matters pertaining to its
rights and duties under this Credit Agreement and the other Loan Documents. The
Agent may utilize the services of such Persons as the Agent in its sole
discretion may reasonably determine, and all reasonable fees and expenses of any
such Persons shall be paid by the Borrower.

         16.3. NO LIABILITY. Neither the Agent nor any of its shareholders,
directors, officers or employees nor any other Person assisting them in their
duties nor any agent or employee thereof, shall be liable for any waiver,
consent or approval given or any action taken, or omitted to be taken, in good
faith by it or them hereunder or under any of the other Loan Documents, or in
connection herewith or therewith, or be responsible for the consequences of any
oversight or error of judgment whatsoever, except that the Agent or such other
Person, as the case may be, may be liable for losses due to its willful
misconduct or gross negligence.

         16.4.  NO REPRESENTATIONS.

                  16.4.1. GENERAL. The Agent shall not be responsible for the
         execution or validity or enforceability of this Credit Agreement, the
         Notes, the Letters of Credit, any of the other Loan Documents or any
         instrument at any time constituting, or intended to constitute,
         collateral security for the Notes, or for the value of any such
         collateral security or for the validity, enforceability or
         collectability of any such amounts owing with respect to the Notes, or
         for any recitals or statements, warranties or representations made
         herein or in any of the other Loan Documents or in any certificate or
         instrument hereafter furnished to it by or on behalf of the Borrower or
         any of its Subsidiaries, or be bound to ascertain or inquire as to the
         performance or observance of any of the terms, conditions, covenants or
         agreements herein or in any instrument at any time constituting, or
         intended to constitute, collateral security for the Notes or to inspect
         any of the properties, books or records of the Borrower or any of its
         Subsidiaries. The Agent shall not be bound to ascertain whether any
         notice, consent, waiver or request delivered to it by the 

<PAGE>   80




                                      -73-

         Borrower or any holder of any of the Notes shall have been duly
         authorized or is true, accurate and complete. The Agent has not made
         nor does it now make any representations or warranties, express or
         implied, nor does it assume any liability to the Banks, with respect to
         the credit worthiness or financial conditions of the Borrower or any of
         its Subsidiaries. Each Bank acknowledges that it has, independently and
         without reliance upon the Agent or any other Bank, and based upon such
         information and documents as it has deemed appropriate, made its own
         credit analysis and decision to enter into this Credit Agreement.

                  16.4.2. CLOSING DOCUMENTATION, ETC. For purposes of
         determining compliance with the conditions set forth in ss.12, each
         Bank that has executed this Credit Agreement shall be deemed to have
         consented to, approved or accepted, or to be satisfied with, each
         document and matter either sent, or made available, by the Agent or
         BancBoston Securities Inc., as arranger to such Bank for consent,
         approval, acceptance or satisfaction, or required thereunder to be to
         be consent to or approved by or acceptable or satisfactory to such
         Bank, unless an officer of the Agent or BancBoston Securities Inc.
         active upon the Borrower's account shall have received notice from such
         Bank not less than two (2) days prior to the Closing Date specifying
         such Bank's objection thereto and such objection shall not have been
         withdrawn by notice to the Agent or BancBoston Securities Inc. to such
         effect on or prior to the Closing Date.

         16.5.  PAYMENTS.

                  16.5.1. PAYMENTS TO AGENT. A payment by the Borrower to the
         Agent hereunder or any of the other Loan Documents for the account of
         any Bank shall constitute a payment to such Bank. The Agent agrees
         promptly to distribute to each Bank such Bank's pro rata share of
         payments received by the Agent for the account of the Banks except as
         otherwise expressly provided herein or in any of the other Loan
         Documents.

                  16.5.2. DISTRIBUTION BY AGENT. If in the opinion of the Agent
         the distribution of any amount received by it in such capacity
         hereunder, under the Notes or under any of the other Loan Documents
         might involve it in liability, it may refrain from making distribution
         until its right to make distribution shall have been adjudicated by a
         court of competent jurisdiction. If a court of competent jurisdiction
         shall adjudge that any amount received and distributed by the Agent is
         to be repaid, each Person to whom any such distribution shall have been
         made shall either repay to the Agent its proportionate share of the
         amount so adjudged to be repaid or shall pay over the same in such
         manner and to such Persons as shall be determined by such court.

                  16.5.3. DELINQUENT BANKS. Notwithstanding anything to the
         contrary contained in this Credit Agreement or any of the other Loan
         Documents, any Bank that fails (a) to make available to the Agent its
         pro rata share of any Loan or to purchase any Letter of Credit
         Participation or (b) to comply with the provisions of ss.15 with
         respect to making dispositions and arrangements with the other Banks,
         where such Bank's share of any payment received, whether by setoff or
         otherwise, is 

<PAGE>   81





                                      -74-

         in excess of its pro rata share of such payments due and payable to all
         of the Banks, in each case as, when and to the full extent required by
         the provisions of this Credit Agreement, shall be deemed delinquent (a
         "Delinquent Bank") and shall be deemed a Delinquent Bank until such
         time as such delinquency is satisfied. A Delinquent Bank shall be
         deemed to have assigned any and all payments due to it from the
         Borrower, whether on account of outstanding Loans, Unpaid Reimbursement
         Obligations, interest, fees or otherwise, to the remaining
         nondelinquent Banks for application to, and reduction of, their
         respective pro rata shares of all outstanding Loans and Unpaid
         Reimbursement Obligations. The Delinquent Bank hereby authorizes the
         Agent to distribute such payments to the nondelinquent Banks in
         proportion to their respective pro rata shares of all outstanding Loans
         and Unpaid Reimbursement Obligations. A Delinquent Bank shall be deemed
         to have satisfied in full a delinquency when and if, as a result of
         application of the assigned payments to all outstanding Loans and
         Unpaid Reimbursement Obligations of the nondelinquent Banks, the Banks'
         respective pro rata shares of all outstanding Loans and Unpaid
         Reimbursement Obligations have returned to those in effect immediately
         prior to such delinquency and without giving effect to the nonpayment
         causing such delinquency.

         16.6. HOLDERS OF NOTES. The Agent may deem and treat the payee of any
Note or the purchaser of any Letter of Credit Participation as the absolute
owner or purchaser thereof for all purposes hereof until it shall have been
furnished in writing with a different name by such payee or by a subsequent
holder, assignee or transferee.

         16.7. INDEMNITY. The Banks ratably agree hereby to indemnify and hold
harmless the Agent and its affiliates from and against any and all claims,
actions and suits (whether groundless or otherwise), losses, damages, costs,
expenses (including any expenses for which the Agent or such affiliate has not
been reimbursed by the Borrower as required by ss.17), and liabilities of every
nature and character arising out of or related to this Credit Agreement, the
Notes, or any of the other Loan Documents or the transactions contemplated or
evidenced hereby or thereby, or the Agent's actions taken hereunder or
thereunder, except to the extent that any of the same shall be directly caused
by the Agent's willful misconduct or gross negligence.

         16.8. AGENT AS BANK. In its individual capacity, BKB shall have the
same obligations and the same rights, powers and privileges in respect to its
Commitment and the Loans made by it, and as the holder of any of the Notes and
as the purchaser of any Letter of Credit Participations, as it would have were
it not also the Agent.

         16.9. RESIGNATION. The Agent may resign at any time by giving sixty
(60) days prior written notice thereof to the Banks and the Borrower. Upon any
such resignation, the Majority Banks shall have the right to appoint a successor
Agent. Unless a Default or Event of Default shall have occurred and be
continuing, such successor Agent shall be reasonably acceptable to the Borrower.
If no successor Agent shall have been so appointed by the Majority Banks and
shall have accepted such appointment within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, which shall be a financial institution
having a rating of not less than A or its equivalent by Standard & Poor's
Corporation. Upon the acceptance 

<PAGE>   82



                                      -75-

of any appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations hereunder. After any retiring Agent's
resignation, the provisions of this Credit Agreement and the other Loan
Documents shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Agent.

         16.10. NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Bank hereby
agrees that, upon learning of the existence of a Default or an Event of Default,
it shall promptly notify the Agent thereof. The Agent hereby agrees that upon
receipt of any notice under this ss.16.10 it shall promptly notify the other
Banks of the existence of such Default or Event of Default.

         16.11. DUTIES IN THE CASE OF ENFORCEMENT. In case one of more Events of
Default have occurred and shall be continuing, and whether or not acceleration
of the Obligations shall have occurred, the Agent shall, if (a) so requested by
the Majority Banks and (b) the Banks have provided to the Agent such additional
indemnities and assurances against expenses and liabilities as the Agent may
reasonably request, proceed to enforce the provisions of the Security Documents
authorizing the sale or other disposition of all or any part of the Collateral
and exercise all or any such other legal and equitable and other rights or
remedies as it may have in respect of such Collateral. The Majority Banks may
direct the Agent in writing as to the method and the extent of any such sale or
other disposition, the Banks hereby agreeing to indemnify and hold the Agent,
harmless from all liabilities incurred in respect of all actions taken or
omitted in accordance with such directions, provided that the Agent need not
comply with any such direction to the extent that the Agent reasonably believes
the Agent's compliance with such direction to be unlawful or commercially
unreasonable in any applicable jurisdiction.

                        17. EXPENSES AND INDEMNIFICATION.

         17.1. EXPENSES. The Borrower agrees to pay (a) the reasonable costs of

withholding tax) on or with respect to the transactions contemplated by this
Credit Agreement (the Borrower hereby agreeing to indemnify the Agent and each

other instruments mentioned herein, (e) all reasonable out-of-pocket expenses
(including without limitation reasonable attorneys' fees and costs, which
attorneys may be employees of any Bank or the Agent, and reasonable consulting,

harmless the Agent, its affiliates and the Banks from and against any and all
claims, actions and suits whether groundless or otherwise, and from and against
any and all liabilities, losses, damages and expenses of every nature and
character arising out of this Credit Agreement or any of the other Loan
Documents or the transactions contemplated hereby including, without limitation,

Borrower or any of its Subsidiaries entering into or performing this Credit
Agreement or any of the other Loan Documents or (d) with respect to the Borrower
and its Subsidiaries and their respective properties and assets, the violation

to, claims with respect to wrongful death, personal injury or damage to
property), in each case including, without limitation, the reasonable fees and
disbursements of counsel and allocated costs of internal counsel incurred in
connection with any such investigation, litigation or other proceeding, except
to the extent that any of the foregoing are directly caused by the gross
negligence or willful misconduct of the otherwise indemnified party. In
litigation, or the preparation therefor, the Banks and the Agent and its
affiliates shall be entitled to select their own counsel and, in addition to the
foregoing indemnity, the Borrower agrees to pay promptly the reasonable fees and
expenses of such counsel. If, and to the extent that the obligations of the
Borrower under this ss.17.2 are unenforceable for any reason, the Borrower
hereby agrees to make the maximum contribution to the payment in satisfaction of
such obligations which is permissible under applicable law.

         17.3. SURVIVAL. The covenants contained in this ss.17 shall survive
payment or satisfaction in full of all other Obligations.

                        18. SURVIVAL OF COVENANTS, ETC.

in the Notes, in any of the other Loan Documents or in any documents or other
papers delivered by or on behalf of the Borrower or any of its Subsidiaries
pursuant hereto shall be deemed to have been relied upon by the Banks and the
Agent, notwithstanding any investigation 

<PAGE>   84

heretofore or hereafter made by any of them, and shall survive the making by the
Banks of any of the Loans and the issuance, extension or renewal of any Letters
of Credit, as herein contemplated, and shall continue in full force and effect
so long as any Letter of Credit or any amount due under this Credit Agreement or
the Notes or any of the other Loan Documents remains outstanding or any Bank has
any obligation to make any Loans or the Agent has any obligation to issue,
extend or renew any Letter of Credit, and for such further time as may be
otherwise expressly specified in this Credit Agreement. All statements contained
in any certificate or other paper delivered to any Bank or the Agent at any time
by or on behalf of the Borrower or any of its Subsidiaries pursuant hereto or in
connection with the transactions contemplated hereby shall constitute
representations and warranties by the Borrower or such Subsidiary hereunder.

         the Borrower and its Subsidiaries or any other Person primarily or
         secondarily liable in respect of any of the Obligations, or the
         performance or observance by the Borrower and its Subsidiaries or any
         other Person primarily or secondarily liable in respect of any of the
         Obligations of any of their obligations under this Credit Agreement or

                  (d) such assignee will, independently and without reliance
         upon the assigning Bank, the Agent or any other Bank 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;

                  (e) such assignee represents and warrants that it is an
         Eligible Assignee;

                  (f) such assignee appoints and authorizes the Agent to take

         are reasonably incidental thereto;

                  (g) such assignee agrees that it will perform in accordance
         with their terms all of the obligations that by the terms of this
         Credit Agreement are required to be performed by it as a Bank;

                  (h) such assignee represents and warrants that it is legally

Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Agent and the Banks may treat each Person whose name is recorded
in the Register as a Bank hereunder for all purposes of this Credit Agreement.
The 
<PAGE>   86



                                      -79-


Register shall be available for inspection by the Borrower and the Banks at
any reasonable time and from time to time upon reasonable prior notice. Upon
each such recordation, the assigning Bank agrees to pay to the Agent a
registration fee in the sum of $3,500.

         19.4. NEW NOTES. Upon its receipt of an Assignment and Acceptance
executed by the parties to such assignment, together with each Note subject to
such assignment, the Agent shall (a) record the information contained therein in
the Register, and (b) give prompt notice thereof to the Borrower and the Banks
(other than the assigning Bank). Within five (5) Business Days after receipt of
such notice, the Borrower, at its own expense, shall execute and deliver to the
Agent, in exchange for each surrendered Note, a new Note to the order of such
Eligible Assignee in an amount equal to the amount assumed by such Eligible
Assignee pursuant to such Assignment and Acceptance and, if the assigning Bank
has retained some portion of its obligations hereunder, a new Note to the order
of the assigning Bank in an amount equal to the amount retained by it hereunder.
Such new Notes shall provide that they are replacements for the surrendered
Notes, shall be in an aggregate principal amount equal to the aggregate
principal amount of the surrendered Notes, shall be dated the effective date of
such in Assignment and Acceptance and shall otherwise be substantially the form
of the assigned Notes. Within five (5) days of issuance of any new Notes

addressed to the Banks and the Agent, relating to the due authorization,
execution and delivery of such new Notes and the legality, validity and binding
effect thereof, in form and substance satisfactory to the Banks. The surrendered
Notes shall be cancelled and returned to the Borrower.

         19.5. PARTICIPATIONS. Each Bank may sell participations to one or more
banks or other entities in all or a portion of such Bank's rights and
obligations under this Credit Agreement and the other Loan Documents; provided
that (a) each such participation shall be in an amount of not less than
$2,500,000, (b) any such sale or participation shall not affect the rights and
duties of the selling Bank hereunder to the Borrower and (c) the only rights
granted to the participant pursuant to such participation arrangements with
respect to waivers, amendments or modifications of the Loan Documents shall be
the rights to approve waivers, amendments or modifications that would reduce the
principal of or the interest rate on any Loans, extend the term or increase the
amount of the Commitment of such Bank as it relates to such participant, reduce
the amount of any commitment fees or Letter of Credit Fees to which such
participant is entitled or extend any regularly scheduled payment date for
principal or interest.

made in accordance with standard and customary banking practices any Bank may
disclose information obtained by such Bank pursuant to this Credit Agreement to
assignees or participants and potential assignees or participants hereunder;
provided that such assignees or participants or potential assignees or
participants shall agree (a) to treat in confidence such information unless such
information otherwise becomes public knowledge, (b) not to disclose such
information to a third party, except as required by law or legal process and (c)
not to make use of such information for purposes of transactions unrelated to
such contemplated assignment or participation.

         19.7. ASSIGNEE OR PARTICIPANT AFFILIATED WITH THE BORROWER. If any
assignee Bank is an Affiliate of the Borrower, then any such assignee Bank shall
have no right to vote as a Bank hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Agent pursuant to ss.14.1 or ss.14.2, and
the determination of the Majority Banks shall for all purposes of this Credit
Agreement and the other Loan Documents be made without regard to such assignee
Bank's interest in any of the Loans or Reimbursement Obligations. If any Bank
sells a participating interest in any of the Loans or Reimbursement Obligations
to a participant, and such participant is the Borrower or an Affiliate of the
Borrower, then such transferor Bank shall promptly notify the Agent of the sale
of such participation. A transferor Bank shall have no right to vote as a Bank
hereunder or under any of the other Loan Documents for purposes of granting
consents or waivers or for purposes of agreeing to amendments or modifications
to any of the Loan Documents or for purposes of making requests to the Agent
pursuant to ss.14.1 or ss.14.2 to the extent that such participation is
beneficially owned by the Borrower or any Affiliate of the Borrower, and the
determination of the Majority Banks shall for all purposes of this Credit
Agreement and the other Loan Documents be made without regard to the interest of
such transferor Bank in the Loans or Reimbursement Obligations to the extent of
such participation.

         19.8. MISCELLANEOUS ASSIGNMENT PROVISIONS. Any assigning Bank shall
retain its rights to be indemnified pursuant to ss.17 with respect to any claims
or actions arising prior to the date of such assignment. If any assignee Bank is
not incorporated under the laws of the United States of America or any state
thereof, it shall, prior to the date on which any interest or fees are payable
hereunder or under any of the other Loan Documents for its account, deliver to
the Borrower and the Agent certification as to its exemption from deduction or
withholding of any United States federal income taxes. If any Reference Bank
transfers all of its interest, rights and obligations under this Credit
Agreement, the Agent shall, in consultation with the Borrower and with the
consent of the Borrower and the Majority Banks, appoint another Bank to act as a
Reference Bank hereunder. Anything contained in this ss.20 to the contrary
notwithstanding, any Bank may at any time pledge all or any portion of its
interest and rights under this Credit Agreement (including all or any portion of
its Notes) to any of the twelve Federal Reserve Banks organized under ss.4 of
the Federal Reserve Act, 12 U.S.C. ss.341. No such pledge or the enforcement
thereof shall release the pledgor Bank from its obligations hereunder or under
any of the other Loan Documents.

         19.9. ASSIGNMENT BY BORROWER. The Borrower shall not assign or transfer
any of its rights or obligations under any of the Loan Documents without the
prior written consent of each of the Banks.

$___________________                                     as of January 28, 1998


         FOR VALUE RECEIVED, the undersigned WESTERN DIGITAL CORPORATION, a
Delaware corporation (the "Borrower"), hereby promises to pay to the order of
[INSERT NAME OF LENDER] (the "Bank") at the Agent's Head Office (as such term is
defined in the Credit Agreement referred to below):

                  (a) prior to or on Revolving Credit Loan Maturity Date the
         principal amount of ______________ DOLLARS ($______________) or, if
         less, the aggregate unpaid principal amount of Revolving Credit Loans
         advanced by the Bank to the Borrower pursuant to the Revolving Credit
         and Term Loan Agreement dated as of January 28, 1998 (as amended and in
         effect from time to time, the "Credit Agreement"), among the Borrower,
         the Bank and other parties thereto;

                  (b) the principal outstanding hereunder from time to time at
         the times provided in the Credit Agreement; and

                  (c) interest on the principal balance hereof from time to time
         outstanding from the Closing Date under the Credit Agreement through
         and including the maturity date hereof at the times and at the rate
         provided in the Credit Agreement.

         This Note evidences borrowings under and has been issued by the
Borrower in accordance with the terms of the Credit Agreement. The Bank and any
holder hereof is entitled to the benefits of the Credit Agreement, the Security
Documents and the other Loan Documents, and may enforce the agreements of the
Borrower contained therein, and any holder hereof may exercise the respective
remedies provided for thereby or otherwise available in respect thereof, all in
accordance with the respective terms thereof. All capitalized terms used in this
Note and not otherwise defined herein shall have the same meanings herein as in
the Credit Agreement.

         The Borrower irrevocably authorizes the Bank to make or cause to be
made, at or about the time of the Drawdown Date of any Revolving Credit Loan or
at the time of receipt of any payment of principal of this Note, an appropriate
notation on the grid attached to this Note, or the continuation of such grid, or
any other similar record, including computer records, reflecting the making of
such Revolving Credit

                                      -2-


Loan or (as the case may be) the receipt of such payment. The outstanding amount
of the Revolving Credit Loans set forth on the grid attached to this Note, or
the continuation of such grid, or any other similar record, including computer
records, maintained by the Bank with respect to any Revolving Credit Loans shall
be prima facie evidence of the principal amount thereof owing and unpaid to the
Bank, but the failure to record, or any error in so recording, any such amount
on any such grid, continuation or other record shall not limit or otherwise
affect the obligation of the Borrower hereunder or under the Credit Agreement to
make payments of principal of and interest on this Note when due.

         The Borrower has the right in certain circumstances and the obligation
under certain other circumstances to prepay the whole or part of the principal
of this Note on the terms and conditions specified in the Credit Agreement.

         If any one or more of the Events of Default shall occur, the entire
unpaid principal amount of this Note and all of the unpaid interest accrued
thereon may become or be declared due and payable in the manner and with the
effect provided in the Credit Agreement.

         No delay or omission on the part of the Bank or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Bank or such holder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar or waiver of the same or any other right on
any further occasion.

         The Borrower and every endorser and guarantor of this Note or the
obligation represented hereby waives presentment, demand, notice, protest and
all other demands and notices in connection with the delivery, acceptance,
performance, default or enforcement of this Note, and assents to any extension
or postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of collateral and to the addition or release
of any other party or person primarily or secondarily liable.

         THIS NOTE AND THE OBLIGATIONS OF THE BORROWER HEREUNDER SHALL FOR ALL
PURPOSES BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE
COMMONWEALTH OF MASSACHUSETTS (EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR
CHOICE OF LAW). THE BORROWER AGREES THAT ANY SUIT FOR THE ENFORCEMENT OF THIS
NOTE MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS OR ANY
FEDERAL COURT SITTING THEREIN AND THE CONSENT TO THE NONEXCLUSIVE JURISDICTION
OF SUCH COURT AND THE SERVICE OF PROCESS IN ANY SUCH SUIT BEING MADE UPON THE
BORROWER BY MAIL AT THE ADDRESS SPECIFIED IN SS.20 OF THE CREDIT AGREEMENT. THE
BORROWER HEREBY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE
VENUE OF ANY SUCH SUIT

         amount of _______________ DOLLARS ($___________), evidencing the Term
         Loan made by the Bank to the Borrower pursuant to the Revolving Credit
         and Term Loan Agreement dated as of January 28, 1998 (as amended and in
         effect from time to time, the "Credit Agreement"), by and among the
         Borrower, the Bank and other parties thereto;

                  (b) the principal outstanding hereunder from time to time at

Borrower in accordance with the terms of the Credit Agreement. The Bank and any
holder hereof is entitled to the benefits of the Credit Agreement, the Security
Documents and the other Loan Documents, and may enforce the agreements of the

                                      -2-


prima facie evidence of the principal amount of the Term Loan owing and unpaid
to the Bank, but the failure to record, or any error in so recording, any such
amount on any such grid, continuation or other record shall not limit or
otherwise affect the obligation of the Borrower hereunder or under the Credit
Agreement to make payments of principal of and interest on this Note when due.

         The Borrower has the right in certain circumstances and the obligation
under certain other circumstances to prepay the whole or part of the principal

unpaid principal amount of this Note and all of the unpaid interest accrued
thereon may become or be declared due and payable in the manner and with the
effect provided in the Credit Agreement.

         No delay or omission on the part of the Bank or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Bank or such holder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar or waiver of the same or any other right on
any future occasion.

         The Borrower and every endorser and guarantor of this Note or the
obligation represented hereby waives presentment, demand, notice, protest and
all other demands and notices in connection with the delivery, acceptance,
performance, default or enforcement of this Note, and assents to any extension
or postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of collateral and to the addition or release
of any other party or person primarily or secondarily liable.

         THIS NOTE AND THE OBLIGATIONS OF THE BORROWER HEREUNDER SHALL FOR ALL
PURPOSES BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE
COMMONWEALTH OF MASSACHUSETTS (EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR
CHOICE OF LAW). THE BORROWER AGREES THAT ANY SUIT FOR THE ENFORCEMENT OF THIS
NOTE MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS OR ANY
FEDERAL COURT SITTING THEREIN AND THE CONSENT TO THE NONEXCLUSIVE JURISDICTION
OF SUCH COURT AND THE SERVICE OF PROCESS IN ANY SUCH SUIT BEING MADE UPON THE
BORROWER BY MAIL AT THE ADDRESS SPECIFIED IN SS.20 OF THE CREDIT AGREEMENT. THE
BORROWER HEREBY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE
VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH SUIT IS BROUGHT IN AN
