1.       Basis of Presentation

         In the opinion of management, the unaudited condensed consolidated
         interim financial statements included herein have been prepared on the
         same basis as the March 31, 1996 audited consolidated financial
         statements and include all adjustments, consisting of only normal
         recurring adjustments, necessary to fairly state the information set
         forth herein. The statements have been prepared in accordance with the
         regulations of the Securities and Exchange Commission, but omit certain
         information and footnote disclosures necessary to present the

         on Form 10-K for the year ended March 31, 1996. The results of
         operations for the three month period ended June 28, 1996 are not
         necessarily indicative of the results to be expected for the entire
         year.

4.       Net Income Per Share

         Net income per share for the three month periods ended June 28, 1996
         and June 30, 1995, is computed under the treasury stock method using
         the weighted average common and common equivalent shares from dilutive
         stock options outstanding during the respective periods.

5.       Acquisitions

         On April 9, 1996, the Company acquired certain assets and the ongoing
         business of Western Digital's Connectivity Solutions Group (CSG) for
         $33 million cash. CSG supplies silicon solutions to meet the demands of
         the multi-gigabyte SCSI disk drive market. Additionally, on June 28,
         1996, the Company acquired certain technologies from Corel, Inc. for
         $12 million cash.

         The Company accounted for these acquisitions using the purchase method
         of accounting, and excluding the $26.5 million write-off of purchased
         in-process technology from these companies, the aggregate impact on the
         Company's results of operations from the acquisition date was not
         material.

         The allocation of the Company's aggregate purchase price to the
         tangible and identifiable intangible assets acquired was based on
         preliminary independent appraisals and is summarized as follows (in
         thousands):

                                                         ========
</TABLE>

6.       Income Taxes

         The Company's effective tax rate of 41% for the first quarter of fiscal
         1997 differed from the 25% rate accrued in the first quarter of fiscal
         1996 primarily due to valuation allowances recorded against deferred
         tax assets generated by the write-off of in-process technology. The
         valuation allowances are appropriate due to sufficient uncertainty
         regarding recoverability during the 15 year amortization period
         required for tax purposes for in-process technology. Also, the
         effective tax rate for the three month period ended June 30, 1995
         differed from the federal statutory rate primarily due to income earned
         in Singapore where the Company is subject to a significantly lower
         effective tax rate.

Net Revenues

Net revenues increased 46% to $202 million in the first quarter of fiscal 1997
from $138 million in the first quarter of fiscal 1996. This growth was
attributable to increased shipments of the Company's host adapters and
proprietary integrated circuits (ICs) used in mass storage devices. These
increases reflect growth in the high-performance microcomputer markets,
continued demand for SCSI in the client/server environment, and an increase in
the use of diverse peripherals in microcomputer systems compared to the same
period a year ago.

Gross Profit

The gross profit percentage for the first quarter of fiscal 1997 decreased to
57% compared to 59% in the same period of fiscal 1996. The percentage decrease
is due to the mix of products shipped, which included a greater percentage of
mass storage ICs. During the quarter, the Company continued to focus on reducing
component costs as well as implementing design efficiencies. The Company's
ability to maintain current gross profit can be significantly affected by
factors such as the mix of products shipped, competitive price pressures, the
timeliness of volume shipments of new products and the Company's ability to
achieve manufacturing cost reductions.

Operating Expenses

Expenditures for research and development as a percentage of net revenues were
14% for the first quarter in fiscal 1997 compared to 13% for the same period in
fiscal 1996. Actual spending for research and development increased 53% to $28
million in the first quarter of fiscal 1997 from $18 million in the same period
a year ago. This increased spending is a result of the Company's continued
investment in its core SCSI business together with its ongoing commitment to the
development of newer products and technologies including ATM, RAID, and serial
architectures such as Fibre Channel and 1394.

Sales and marketing expenses as a percentage of net revenues were 12% in the
first quarter of both fiscal 1997 and fiscal 1996. Actual spending for sales and
marketing increased 39% to $24 million in the first quarter of fiscal 1997 from
$17 million in the corresponding period in fiscal 1996. This spending increase
was mainly due to increased staffing levels and increased advertising and
promotional activities aimed at introducing new technologies and generating
demand for the Company's products in the microcomputer and file server markets.

General and administrative expenses remained consistent as a percentage of net
revenues at 5% in the first quarter in both fiscal 1997 and 1996.

As discussed under Note 5 of the Notes to Condensed Consolidated Financial
Statements in this report, during the current quarter the Company acquired CSG
and certain technologies from Corel, Inc. for $33 million and $12 million cash,
respectively. These acquisitions were accounted for using the purchase method of
accounting, and the Company recorded a one time after-tax charge of $25 million
for acquired in-process technology. The Company also recorded goodwill of $8
million which will be amortized ratably over a period of five years.

Interest and Income Taxes

Interest income, net of interest expense, in the first quarter of fiscal 1997
was relatively consistent compared to the same period in the prior year. The
Company's effective tax rate of 41% for the first quarter of fiscal 1997
differed from the 25% rate accrued in the first quarter of fiscal 1996 primarily
due to valuation allowances recorded against deferred tax assets generated by
the write-off of in-process technology. The valuation allowances are appropriate
due to sufficient uncertainty regarding recoverability during the 15 year
amortization period required for tax purposes for in-process technology. Also,
the effective tax rate for the three month period ended June 30, 1995 differed
from the federal statutory rate primarily due to income earned in Singapore
where the Company is subject to a significantly lower effective tax rate.

Liquidity and Capital Resources

Operating Activities

Net cash generated by operations for the first quarter of fiscal 1997 was $37
million compared with $41 million for the corresponding quarter of fiscal 1996.
During the first quarter of fiscal 1997, the majority of funds generated from
operations resulted from $18 million of net income adjusted for non-cash items
including a non-recurring write-off of acquired in-process technology of $25
million, and depreciation and amortization of $6 million. The overall decrease
in cash generated from operations compared to the prior year is mainly a result
of the Company's non-cash working capital increasing at a higher rate compared
to the same period a year ago. This increase in working capital included
increases in accounts receivable and inventories of $19 million and $7 million,
respectively, primarily offset by an increase in accrued liabilities of $12
million. These overall increases were mainly attributable to higher revenue
volumes and increased staffing levels.

Investing Activities

As previously discussed, the Company paid a total of $45 million cash for the
acquisitions of CSG and certain technologies from Corel, Inc. During the first
quarter of fiscal 1997, the Company also continued to invest in the purchase of
equipment for product development, IC testing, board level production, and made
various building and leasehold improvements to its facilities. In connection
with an agreement with Lucent Technologies (Lucent, formerly AT&T) to secure
capacity for wafer fabrication, the Company purchased $7 million of fabrication
equipment which is consigned to Lucent's fab in Madrid, Spain.

The Company anticipates capital expenditures relating to property and equipment
of approximately $80 million for the remainder of fiscal 1997. The Company may
also make investments for increased capacity for wafer fabrication or
acquisitions of complimentary businesses, products, or technologies. The Company
believes existing working capital, together with expected cash flows from
operations and available sources of bank, equity, debt and equipment financing,
will be sufficient to support its operations at least through fiscal 1997.

Financing Activities

In connection with an agreement with Taiwan Semiconductor Manufacturing Co.,
Ltd. (TSMC) that ensures availability of a portion of the Company's wafer
capacity for both current and future technologies, the Company paid a short-term
note of $46 million due to TSMC. In return for this advance payment, the Company
will receive guaranteed future wafer capacity and a discount on purchases that
exceed certain prescribed minimum quantities. Additionally, in connection with
this agreement, the Company will receive access to future process technology.

During the first quarter of fiscal 1997 and fiscal 1996, the Company received
proceeds from common stock issued under the employee stock option and employee
stock purchase plans totaling $6 million and $2 million, respectively.

Certain Factors Bearing on Future Results

The following risk factors should be considered by anyone contemplating an
investment in the Company's Common Stock. In addition, the Company and its
representatives may from time to time make forward-looking statements, and the
following are important factors that could cause actual results to differ
materially from those projected in any such forward-looking statements.


                                       10
<PAGE>   11
Reliance on the High-Performance Microcomputer Market. The Company's board-based
I/O solutions are used primarily in high performance computer systems designed
to support I/O intensive applications and operating systems. Historically, the
Company's growth has been supported by increasing demand for systems which
support networking applications, multitasking, CAD/CAM, desktop publishing,
multimedia, and video. Should the growth of demand for such systems slow, the
Company's revenues and income could be adversely affected by a decline in demand
for the Company's products and increased pricing pressures from both competitors
and customers.

Future Operating Results Subject to Fluctuation. The Company's operating results
may fluctuate in the future as a result of a number of factors, including
variations in the Company's sales channels or the mix of products it sells,
changes in pricing policies by the Company's suppliers, the timing of
acquisitions of other businesses, products and technologies and any associated
charges to earnings and the market acceptance of new and enhanced versions of
the Company's products. The volume and timing of orders received during a
quarter are difficult to forecast. Customers generally order on an as-needed
basis and, accordingly, the Company has historically operated with a relatively
small backlog, especially relating to orders of its board-based I/O solutions.
Further, the Company's expense levels are based in part on expectations of
future revenues, and the Company has been significantly increasing and intends
to continue to increase operating expenditures and inventory as it expands its
operations. As a result of the difficulty of forecasting revenues and the
Company's planned growth in spending, operating expenses and inventory levels
could be disproportionately high for a given quarter, and the Company's
operating results for that quarter, and potentially future quarters, would be
adversely affected. Operating results in any particular quarter which do not
meet the expectations of securities analysts or investors could cause volatility
in the price of the Company's Common Stock.

Uncertainty of Timing and Amount of Capital Expenditures. Predicting the timing
and amount of capital expenditures is difficult for a number of reasons,
including (i) the fact that opportunities to acquire other businesses, products
and technologies of interest to the Company may arise on short notice and
require substantial amounts of capital and (ii) that in the increasingly
competitive market for wafer supplies, wafer manufacturers have been frequently
requiring substantial capital commitments by customers in order to obtain
guaranteed wafer capacity. Opportunities to obtain such capacity can arise on
relatively short notice and require significant commitments on the part of the
Company.

Dependence on Suppliers. The majority of the Company's ICs are manufactured by
TSMC and a limited number of manufacturers. If one or more of these
manufacturers were to experience significant difficulty or disruptions in the
shipment of ICs, delays in developing alternative sources could adversely affect
the Company's business. In addition, the Company's host adapter products make
extensive use of standard logic, memory and microprocessor circuits. An extended
supply shortage or a major increase in the market price of these components
could have an adverse effect on the Company's business.

International Operations and Markets. The Company's manufacturing facility and
various subcontractors it utilizes from time-to-time are primarily located in
Asia. Additionally the Company has various sales offices and customers
throughout Europe, Japan, and other countries. The Company's international
operations and sales may be subject to political and economic risks, including
political instability, currency controls, exchange rate fluctuations, and
changes in import/export regulations, tariffs and freight rates. There can be no
assurance that the political and economic risks to which the Company is subject
will not result in customers of the Company defaulting on payments due to the
Company or in the reduction of potential purchases of the Company's products.


                                       11
<PAGE>   12
Fluctuation in Demand. The Company's customers encounter uncertain and changing
demand for their products. They typically order products from the Company based
on their forecasts. If demand falls below customers' forecasts, or if customers
do not control their inventories effectively, they may cancel or reschedule
shipments previously ordered from the Company. The Company has in the past
experienced, and may at any time and with minimal notice in the future
experience, cancellations and postponements of orders.

Management of Growth and Acquisitions. The Company recently has experienced
growth in the number of its employees and the scope of its operations and has
completed several acquisitions of other companies resulting in increased
responsibilities for its management. In order to manage potential future growth
and acquisitions, the Company will need to hire, train, motivate and manage a
growing number of employees. A failure to effectively manage growth or
acquisitions could materially adversely affect the Company's business and
operating results.

Reliance on Industry Standards. The Company's products are designed to conform
with certain industry standards such as SCSI, UltraSCSI, PCI, RAID and ATM. If
consumer acceptance of these standards was to decline or if new standards were
to emerge, the Company's business and operating results could be materially
adversely affected.

Technological Change; Competition; Dependence on New Products. The markets for
the Company's products are characterized by rapidly changing technology,
frequent new product introductions and declining average selling prices over
product life cycles. The Company's future success is highly dependent upon the
timely completion and introduction of new products at competitive
price/performance levels. In addition, the Company must respond to current
competitors, who may choose to increase their presence in the Company's markets,
and to new competitors, who may choose to enter those markets. If the Company is
unable to make timely introduction of new products or respond to competitive
threats, its business and operating results could be materially adversely
affected.

Volatility of Stock Price. In recent months, the stock market in general, and
the market for share of technology companies in particular, have experienced
extreme price fluctuations, which have often been unrelated to the operating
performance of the affected companies. In addition, factors such as
technological innovations or new product introductions by the Company, its
competitors or its customers may have a significant impact on the market price
of the Company's Common Stock. Furthermore, quarter-to-quarter fluctuations in
the Company's results of operations caused by changes in customer demand,
changes in the microcomputer and peripherals markets, or other factors, may have
a significant impact on the market price of the Company's Common Stock. These
conditions, as well as factors which generally affect the market for stocks of
high technology companies, could cause the price of the Company's stock to
fluctuate substantially over short periods.

                    AGREEMENT FOR PURCRASE AND SALE OF STOCK

         THIS STOCK PURCHASE AGREEMENT (this "Agreement") is made as of April 9,
1996 (the "Effective Date"), by and among Western Digital Corporation, a
Delaware corporation with its principal offices at 8105 Irvine Center Drive,
Irvine, Califomia 92718 ("Seller"), Western Digital CSG Corporation, a Delaware
corporation ("Sub"), and Adaptec, Inc., a California corporation with its
principal offices at 691 South Milpitas, Boulevard, Milpitas, California 95035
("Buyer").

                                 R E C I T A L S

         A. Seller has operated a business referred to as the Connectivity
Solutions Group ("CSG"), which has been primarily engaged in the business of
designing, developing, manufacturing, testing, marketing, selling, supporting
and providing related services for control electronics to manufacturers,
distributors and resellers of disk drives and other storage peripherals (such
business as previously and currently conducted is herein referred to as the "CSG
Business").

         B. Buyer desires to acquire the CSG Business in corporate form for a
variety of business reasons including, but not limited to, the following:

            (1) Except as specifically listed in this Agreement, at no time does
Buyer want to assume any of the liabilities of the CSG Business as conducted
through the Effective Date and the acquisition of a newly formed wholly-owned
subsidiary of Seller will allow Buyer to examine the liabilities assumed and
insulate itself and its other assets from any undisclosed or unknown liabilities
associated with the CSG Business;

            (ii) There are numerous assets and several different types of assets
associated with the CSG Business and Buyer believes the use of a separate
corporation will provide it with the ability to more easily separately track the
assets acquired for a period of time to verify the existence and validity (if
necessary) of the assets acquired;

            (iii) The revenue generated by, and the key customers of, the CSG
Business are a material inducement for Buyer entering into this Agreement and
the acquisition of a separate corporation representing the CSG Business will
allow Buyer, for an appropriate period, to separately account for the business
activities of the CSG Business and address these separate revenue sources and
customer matters; and

            (iv) As part of this transaction, Buyer is acquiring various amounts
of inventory property from Seller and Buyer may wish to market such inventory
and/or identify the seller of such inventory under a name other than Buyer's for
marketing reasons and the acquisition of a separate corporation with a separate
legal identity from and different name than Buyer's can assist Buyer in
achieving these acquired inventory sales objectives.

            C. To achieve the above described business purpose of Adaptec, prior
to the Closing Seller shall, as provided herein, contribute certain assets and
liabilities related to the CSG Business to Sub, which is, and prior to the
Closing will be, a wholly-owned subsidiary of Seller.

the CSG Business to Sub as described above, Seller shall sell, and Buyer shall
buy, all of the outstanding shares of Common Stock of Sub, constituting all of 
the issued and outstanding capital stock of Sub (the "Shares"), pursuant to the
terms and conditions set forth in this Agreement.

            E. Upon the closing of the acquisition of the Shares, Seller and

agreements pursuant to which any other Person is authorized to use, exercise, or
receive any benefit from, any Intellectual Property (the "Licenses" and (ii)
Proprietary Rights Agreements. Seller has delivered copies of such Licenses and
Proprietary Rights Agreements to Buyer. Seller and Sub are not, nor will they
be, as a result of the execution and delivery of this Agreement or the Shared
Resource License Agreement or the performance of the party's obligations
hereunder or thereunder, in violation of such Licenses or Proprietary Rights
Agreements.

                    (d) To Seller's knowledge none of its employees,
  consultants, or third party contractors is obligated under any contract
  (including licenses, covenants or commitments of any nature) or other
  agreement, or subject to any judgment, decree or order of any court or
  administrative agency, that could conflict with the conduct of the CSG
  Business by Buyer or its Affiliates or that could interfere with the ability
  of Buyer or its Affiliates to use, license or sell the Transferred Assets or
  Buyer's or its Affiliates' rights with respect to the Shared Resources. The
  execution, delivery and performance of this Agreement, the Contribution
  Agreement, the Related Agreements or the Seller Closing Documents and the
  consummation of the transactions contemplated hereby and thereby by Seller and
  Sub will not conflict with or result in a material breach of the terms,
  conditions or provisions of, or constitute a material default under, any
  contract, covenant or instrument under which any of such employees or
  consultants is now obligated. The conduct of the CSG Business and the exercise
  of rights granted under the Shared Resource License Agreement do not require
  the use of any inventions of any of Seller's or its Affiliates' past or
  present employees or consultants made prior to their employment by Seller or
  its Affiliates, and to Seller's knowledge, neither Seller nor any of its
  Affiliates are using any confidential information or trade secrets of any
  former employer of any past or present employees in connection with the CSG
  Business nor is the use of any such information or trade secrets of any former
  employer inherent in the use of the Shared Resources. Except as disclosed on
  Schedule 6.9, all of the Intellectual Property, Product Rights, Shared
  Resources, Software Programs and Tools have been created by employees or
  consultants of Seller within the scope of their employment by or consulting
  relationship with Seller and such employees or consultants executed valid and
  binding agreements assigning all of their entire right, title and interest in
  the Intellectual Property, Product Rights and Software Programs to Seller.

of operating systems and hardware platform(s) on which the Software Programs,
Tools and Testing Materials operate. Except for general business third party
software which is readily and currently commercially available and not having a
replacement cost of more than $ 1,000 individually and $25,000 in the aggregate
and which is not embedded in or necessary to run any of the Software Programs,
Tools or Testing Materials, no other software is required to operate the

and Testing Materials. Seller and Sub maintain machine-readable
master-reproducible copies, properly documented source code and source code
listings, and technical and user documentation for each Software Program, Tool
and Testing Material, as appropriate; in each case, the machine-readable copy
substantially conforms to the corresponding source code listing; such Software
Programs, Tools and Testing Materials can be maintained and modified by
reasonably competent programmers or engineers who have access to the
Intellectual Property, Software Programs, Tools and Testing Materials; and in

Business Products, except as specifically described on Schedule 6.10 and no
customer of Seller or Sub has prepaid maintenance fees except as specifically
described on Schedule 6.10. The documentation which Seller and Sub are

Software Programs have been published.

binding agreement of the other party or parties thereto. Seller and Sub have
fulfilled all material obligations required pursuant to the Assumed Contracts to

Seller has no reason to believe that Seller or Sub will not be able to fulfill,
when due, all of their respective obligations under the Agreements which remain
to be performed after the date hereof and through the Closing Date. Seller and
Sub are not in breach of or default under any Assumed Contract which could
entitle the other party to terminate the Agreement. Neither the execution and
delivery of this Agreement, the Related Agreements, the performance of the
parties respective obligations hereunder and thereunder, nor any event which has
occurred which with the passage of time or giving of notice or both could
constitute a breach or default under any Assumed Contract, result in a loss of
rights, or create an Encumbrance on or with respect to a Transferred Asset or
Assumed Contract. To the knowledge of Seller, there is no existing breach or
default by any other party to any Assumed Contract which could entitle Seller or
Sub to terminate such Assumed Contract, and no event has occurred which, with
the passage of time or giving of notice or both, could constitute a default by
such other party, result in a loss of rights or result in the creation of any
Encumbrance thereunder or pursuant thereto. With respect to each Agreement,
other than an Assumed Contract, neither the execution and delivery of this
Agreement, the Contribution Agreement, the Related Agreements, the performance
of the parties respective obligations hereunder and thereunder, nor any event
which has occurred which, with the passage of time or giving of notice or both,
would cause a breach or default under such Agreements, result in a loss- of
rights, or result in the creation of any Encumbrance on or with respect to any
Transferred Asset, Shared Resource or Assumed Contract.

Contract and are summarized in Schedule 6.12. Each manufacturing or service site
which requires qualification under the terms of a respective Supply Contract is
qualified, and no unresolved differences with respect to product or process
specifications remains outstanding. All manufacturing or service terms and
conditions are as they appear to be on the face of the respective Supply
Contracts. Seller has not received any written or oral notice from the other

the effect that such party will not accept purchase orders from Seller, Sub or
Buyer on such terms, conditions and quantities consistent with past practices.

timely given. All disputes under such Supply Contracts have been timely
resolved. Prices required to be paid for products or services under such Supply
Contracts are summarized on Schedule 6.12 and are reasonable and no condition

wafer starts and products in production as of the Effective Date, which will be
updated as of the Closing Date. Schedule 6.12 also sets forth manufacturing

         6.20 PRODUCTS LIABILITY. The CSG Business Products do not contain any
defects in design or otherwise (including latent defects) and Seller has not
experienced. and is not experiencing, any material difficulties with respect to
the manufacture of the CSG Business Products. There is no Litigation pending or,
to Seller's knowledge, threatened against or involving Seller or Sub relating to
any of the CSG Business Products alleged to have been manufactured or sold by
Seller or Sub and alleged to have been defective (including latent defects), or
improperly designed or manufactured. All manufacturing standards, testing

schedule of the assets of the CSG Business as at July 1, 1995, (ii) an internal
profit and loss statement for the fiscal year ended July 1, 1995 in relation to
the CSG Business, (iii) a schedule of assets of the CSG Business as at March 30,
1996, and (iv) an Internal profit and loss statement in relation to the CSG
Business for the eight month period ended March 30, 1996 (collectively, the
"FINANCIAL STATEMENTS"). The Financial Records are true, correct and complete.
The financial data included in the Financial Statements fairly presents such
financial information regarding the CSG Business, and the recorded and accrued
amounts set forth in the Financial Statements fairly present the financial
position of the respective assets, revenues, product costs, research and
development and marketing expenses and profits of the CSG Business, as of the
respective dates or for the respective periods indicated thereon. The Financial
Statements, Inventory Reserves, Warranty and Return Expenses, the Closing Date

a manner that is consistent with Seller's internal business and financial
accounting methods, which internal business and financial accounting methods are
in accordance with GAAP.

         6.22 NO UNDISCLOSED LIABILITIES OR ADVERSE CHANGES. Other than the
Assumed Liabilities, Sub has no other debts, liabilities, and obligations of any
nature whether due or to become due (including, without limitation, absolute
liabilities, accrued liabilities and contingent liabilities). To Seller's
knowledge, there are no circumstances, conditions, events or arrangements, that
may be reasonably expected to hereafter give rise to any liabilities of the CSG
Business, other than liabilities arising in the ordinary course. Seller has no
knowledge of any liabilities relating to the CSG Business for breach of
contract, breach of warranty, tort or infringement not specifically disclosed in
the Schedules hereto. Since July 1, 1995 there has been no fact or development
known to Seller which could have a material adverse effect on the condition or
prospects, financial or otherwise, of the CSG Business, the Transferred Assets
or the Shared Resources, nor has there been any damage, destruction or loss,
whether or not covered by insurance, which adversely affects the CSG Business or
the Transferred Assets. During such period, neither Seller nor Sub has not
incurred, and will not incur, any obligation or liability, absolute, accrued,
contingent or otherwise, whether due or to become due other than in the ordinary
course of the CSG Business.

marketing and sales information, pricing, marketing plans, business plans,
financial and business projections, manufacturing processes and procedures,

the course of negotiating the transactions contemplated by this Agreement
"Confidential Information") will be held in confidence and not used or disclosed
by the Receiving Party or any of its employees, Affiliates or stockholders for a
period of five (5) years from the Effective Date and will be promptly destroyed

pursuant to this Agreement becomes legally compelled (by oral questions,
interrogatories, request for information or documents, subpoena, criirlinal or
civil investigative demand or similar process or by statute or regulation) to
disclose any of Confidential Information, the Receiving Party will provide the
Disclosing Party with prompt written notice of that fact so that the Disclosing
Party may seek (with the Receiving Party's cooperation, if so requested by the
Disclosing Party) a protective order, confidential treatment or other
appropriate remedy. In any event, in the circumstance, the Receiving Party will
furnish only that portion of the Confidential Information which is legally
required and will exercise its best efforts to obtain reliable assurances that
confidential treatment will be accorded the Confidential Information. The

as confidential all information submitted to them. Notwithstanding any provision

confidentiality and the protection of the Intellectual Property. In the event
that Buyer or its Affiliates is unable to enforce the rights related to the
Intellectual Property against a third party as a result of a rule or law barring
enforcement of such rights by a transferee of such rights, Seller agrees to
reasonably cooperate with Buyer, at Buyer's expense and with no liability on
Seller's part, by assigning to Buyer or its Affiliates such rights as may be
required by Buyer to enforce the Buyer's rights to the Intellectual Property. If
such assignment still does not permit Buyer to enforce its rights to the
Intellectual Property against the third party, Seller agrees, at Buyer's
expense, to initiate proceedings against such third party in Seller's name,
provided that Buyer shall be entitled to participate in such proceedings, all at
Buyer's expense.

Sub of such Listed Employees, any claims or rights Seller or its Affiliates may
have against Buyer, Sub or any such Listed Employee under any non-competition,
confidentiality or employment agreement to the extent such Listed Employees are
performing services for Buyer or Sub, but only insofar as such services relate
to the CSG Business.

                  (d) In the event of termination of this Agreement by any or
all of the parties pursuant to Section 15 below, the parties hereby agree that
Buyer may not solicit any of the Listed Employees to become employed by Buyer
prior to February 6, 1997; provided, however, that Buyer may at any time solicit
persons not employed by Seller, including Listed Employees, and provided,

from the transfer of the Transferred Assets to Sub;

                  (e) any demand, claim, debt, suit, cause of action,
arbitration or other proceeding (including, but not limited to, a warranty
claim, a strict product liability claim or any other claim) that is made or
asserted by any third party that relates to any product defects, including
latent defects, of any product or service, including any of the CSG Business
Products, provided by Buyer or Sub to any customer after Closing unless such
CSG Business Products (i) were sourced from the Inventory or Customer Inventory
or (ii) are produced after the Closing Date and contain a design defect based on
unmodified designs transferred as part of the Transferred Assets; and (f) 
any demand, claim, debt, suit, cause of action or proceeding made or asserted 
by any employee or independent contractor or any former employee or independent
contractor of Buyer or Sub, that relates in any manner to any termination after
the Closing Date by Buyer or Sub of its employment or the services of such
employee or independent contractor after the Closing Date or any other matter
relating to Buyer's or Sub's employment of such employee or independent
contractor after the Closing Date;

Provided however, that nothing in this Section 13.5 shall impose on Buyer any
duty to indemnify Seller for any Excluded Liabilities.

The indemnification provided for in this Section 13.5 will not apply unless and
until the aggregate Losses for which one or more Seller Indemnitees seeks
indemnification under this Section 13.5 exceeds $375,000, in which event the
indemnification provided in this Section 13.5 will include all such Losses in
excess of $375,000. This $375,000 deductible "bucket" shall not apply to the
Earnout Payment or to Transfer Taxes.

         13.6     INDEMNIFICATION PROCEDURE.

                  (a) Claim. Whenever any Loss shall be asserted against or
incurred by a Buyer Indemnitee or Seller Indemnitee (the "INDEMNIFIED PARTY"),
for which a claim of indemnify can be made under this Section 13, the
Indemnified Party shall give prompt written notice thereof (a "CLAIM") to Seller
or Buyer. as appropriate (the "INDEMNIFYING PARTY"). The Indemnified Party shall
furnish to the Indemnifying Party in reasonable detail such information as the
Indemnified Party may have with respect to the Claim (including in any case
copies of any

                                      -54-
<PAGE>   63
                                                                  EXECUTION COPY

summmons, complaint or other pleading which may have been served on it and any
written claim, I demand, invoice, billing or other document evidencing or
asserting, the same). The failure to give such notice shall not relieve the
Indemnifying Party of its indemnification obligations under this Agreement,
unless and to the extent that the failure to give such notice to the
Indemnifying Party prevents the Indemnifying Party from raising a defense to
the Claim or otherwise materially and adversely affects the Indemnifying
Party's ability to defend against the Claim. The Indemnified Party shall
cooperate in good faith with the Indemnifying Party in resolving any Claim and
shall use commercially reasonably efforts (at the expense of the Indemnifying
Party) to mitigate any Losses which are the subject of such Claim.

                  (b) Dispute of Claim. If the Indemnifying Party disputes the
claim presented in the Claim, the Indemnifying Party shall notify the
Indemnified Party of such disagreement within thirty (30) days of the receipt of
the Claim. Thereupon, the Indemnified Party and the Indemnifying Party will
negotiate in good faith and use reasonable efforts to resolve their differences
with respect to the Claim during the thirty (30) days following the Indemnifying
Party's notice of disagreement to the Indemnified Party. In the event such
dispute is not resolved upon the expiration of the thirty (30) day period
following the Indemnifying Party's notice of disagreement to the Indemnified
Party, the parties shall resolve the dispute in accordance with the terms of
Section 14 hereof.

                   (c) Third Party Claims. Subject to the rights of Buyer under
the provisions of Section 13.6(e) if the Claim is based on a claim of a person
that is not a party to this Agreement ("THIRD PARTY CLAIM"), the Indemnifying
Party shall, at its expense, undertake the defense of such Third Party Claim
with attorneys of its own choosing reasonably satisfactory to the Indemnified
Party. In the event the Indemnifying Party, within a reasonable time after the
separate receiving notice of a Third Party Claim from the Indemnified Party,
fails to defend the Third Party Claim, the Indemnified Party may, at the
Indemnifying Party's expense, undertake the defense of the Third Party Claim and
may compromise or settle the Third Party Claim, all for the account of the
Indemnifying Party. After notice from the Indemnifying Party to the Indemnified
Party of its election to assume the defense of such Third Party Claim, the
Indemnifying Party shall not be liable to the Indemnified Party under this
Section 13.6 for any legal expenses subsequently incurred by the Indemnified
Party in connection with the defense thereof, except for such expenses incurred
in connection with cooperation with, or at the request of, the Indemnifying
Party, provided, however, that the Indemnified Party shall have the right, at
the Indeminifying Party's expense, to employ counsel to represent it if, in the
Indemnified Party's reasonable judgment, based upon the advice of counsel, it is
advisable, in light of the separate interests of the Indemnified Party and the
Indemnifying Party, for the Indemnified Party to be represented by separate
counsel.

                  (d) Consent. The Indemnifying Party shall not consent to entry
of any judament, or enter into any settlement, except with the consent of the
Indemnified Party, which such consent shall not be unreasonably withheld or
delayed. In the event the Indemnified Party refuses to consent to the entry of a
judgment or a settlement for which the Indemnifying Party is solely and
entirely responsible and has indicated its sole and entire responsibility in
writing to the Indemnified Party, following such refusal, the liability of the
Indemnifying Party to the Indemnified Party will be fixed at the amount of money
damages provided in the proposed judgment or settlement.

                   (e) Buyer as Indemnified Party. In connection with any Third
Party Claim ac,ainst Buyer, notwithstanding the provisions of Section 13.6(c) or
(d), Buyer may undertake the defense of such Third Party Claim with attorneys of
its own choosing reasonably satisfactory to the Seller Indemnifying Party. In
connection with such defense Buyer shall notify the Seller of the claim and its
election to undertake the defense thereof. Buyer shall also notify Seller from
time to time or at Seller's request of Buyer's strategy and progress with
respect to such Third Party Claim and provide Seller an opportunity to consult
with Buyer with respect thereto. The Buyer and the Seller shall use their
reasonable efforts and attempt in good faith to agree on strategy, settlement
and other issues in connection with such Third Party Claim. Buyer shall promptly
notify Seller of any written settlement offer with respect to such Third Party
Claims. In addition, counsel for any Seller shall be permitted to monitor the
Buyer's defense of such Third Party Claim for the purpose of advising the Buyer
of the status and progress of the defense. Any such activity shall be at the
sole expense of the Seller. Notwithstanding the above, Buyer may defend against,
and consent to the entry of any judgment or enter into any settlement with
respect to any Third Party Claim, in a manner that the Buyer in good faith
reasonably deems appropriate, and the Seller will remain responsible for any
Loss Buyer may suffer resulting from, arising out of, relating to, in the nature
of, or caused by such Third Party Claim, including the reasonable legal fees and
expenses associated with Buyer undertaking the defense of such Third Party
Claim. Notwithstanding the foregoing, if (i) Buyer is offered a written
settlement proposal by a third party that has as its sole component the payment
of money by Buyer, (ii) Seller recommends to Buyer in writing that Buyer accept
such settlement proposal (the "SELLER SANCTIONED SETTLEMENT") and (iii) Buyer
refuses to accept such settlement proposal, then in such event if the ultimate
settlement terms agreed to by Buyer with such third party or the final monetary
damages award against Buyer Indemnitees, after exhaustion of all appeals (either
referred to as the "FINAL SETTLEMENT AMOUNT"), is greater than the amount of the
Seller Sanctioned Settlement, Buyer shall be responsible for the differential
between the Final Settlement Amount and the Seller Sanctioned Settlement and
Seller's liability shall be limited to the amount specified in the Seller
Sanctioned Settlement, subject to the maximum indemnification obligations of
Seller under Sections 13.3 and 13.4.

           13.7 PERIOD FOR MAKING CLAIMS. A claim for indemnification under
  this Section 13 may be brought, if at all, at any time after the Closing Date,
  with respect to any claim or claims for indemnification under this Section 13;
  provided, however, any claim under Sections 13.3(a) or 13.5(a) with respect to
  the inaccuracy or misrepresentation of a representation or warranty must be
  brought, if at all, at any time prior to the time such representation or
  warranty expires pursuant to Section 13. 1.

  14.      DISPUTE RESOLUTION.

           14.1     MANAGEMENT NEGOTIATION.

                    (a) The Buyer and Seller shall attempt to resolve disputes
  between the Buyer and the Seller arising out of or in connection with this
  Agreement through good faith negotiations as provided herein. The parties
  agree that disputes shall be fully discussed by the functional representatives
  of the Buyer and the Seller involved in the dispute in an attempt to achieve a
  prompt resolution of such dispute. In the event that such dispute shall not be
  promptly resolved

by the mutual agreement of the functional representatives of the Buyer and the
Seller, the dispute shall be submitted to senior management representatives of
each of the Buyer and the Seller. Such senior management representatives of the
Buyer and the Seller shall meet and fully discuss such dispute in an attempt to
achieve a prompt resolution of the dispute. If such dispute is not promptly
resolved by the mutual agreement of such senior management representatives of
the Buyer and the Seller, each of the Buyer and the Seller shall be free to
exercise any of the remedies available to it (i) pursuant to the terms of this
Agreement or (ii) otherwise at law or in equity.

                  (b) The Buyer and the Seller acknowledge that, from time to
time, certain material disputes arising out of or in connection with this
Agreement may objectively require immediate resolutions. Accordingly, any such
dispute may, at the option of either the Buyer or the Seller, be processed
through an abbreviated mediation process. Such abbreviated mediation process
shall entail submitting any such dispute to the senior management
representatives of each of the Buyer and Seller designated by each of the Buyer
and the Seller for a prompt and expeditious resolution. In the event that a
prompt and expeditious resolution of such dispute is not achieved through the
mutual agreement of such senior management representatives of the Buyer and the
Seller, each of the Buyer and the Seller shall be free to exercise any of the
remedies available to it (i) pursuant to the terms of this Agreement or (ii)
otherwise at law or in equity.

                  (c) Each of the Buyer and the Seller agrees to act reasonably
and in good faith in connection with all matters arising out of or in
connection with this Agreement that are submitted to the mediation process set
forth in this Section 14.

           14.2 WAIVER OF JURY TRIAL. The parties hereby waive trial by
jury in any litigation in any court with respect to, in connection with, or
arising out of this Agreement or the transactions contemplated thereby.

           15.    TERMINATION

           15.1   TERMINATION OF AGREEMENT.  This Agreement may be

                  (a) By mutual written consent of Buyer and Seller;

                  (b) By Buyer or Seller if there is a lawsuit, action or
proceeding brought by a third party or Governmental Body Entity with respect to
the transactions contemplated hereby;

                  (c) By Buyer or Seller if the other party breaches in any
material respect any of its obligations (including its representations,
warranties or covenants) under this Agreement; (d) By Buyer or Seller if the
parties do not receive the required approvals and clearances pursuant to the HSR
Act by May 1, 1996; or

                  (e) By Buyer or Seller if the Closing has not occurred on or
before May 1, 1996.

of this Agreement by any or all of the parties pursuant to Section 15.1
hereof, written notice thereof shall forthwith be given to each other party
specifying the provision hereof pursuant to which such termination is made and,
except for those terms of this Agreement which survive a termination, including
without limitation the provisions contained in Sections 7.1, 11.1(d), 10.4,
14.2, 15.3 and 17 hereof, this Agreement shall forthwith become void and there
shall be no liability on the part of the parties hereto (or their respective
officers, directors, partners, Affiliates, successors or assigns), except as set
forth in Section 15.3 below.

         15.3 REIMBURSEMENT OF PREPAID PURCHASE PRICE: SOLE REMEDY. In the event
that Closing of the transactions contemplated by this Agreement does not occur
because of a "Permitted Reason" then, in addition to any other remedies
available to Buyer, Seller shall reimburse Buyer the First Deposit and the
Second Deposit previously paid to Seller. A Permitted Reason shall mean (i)
breach by Seller of any of its obligations (including its representations,
warranties and covenants as provided in this Agreement) to consummate the
transactions contemplated thereunder; (ii) the parties do not receive the
required approvals and clearances pursuant to the HSR, by May 1, 1996; (iii)

in light of the circumstances under which they were made, not misleading; or (v)
on or prior to May 1, 1996 the Listed Employees Closing Condition, the ST
Agreement Closing Condition or the IBM Agreement Closing Condition has not been

Agreement, Seller shall have the right to retain all amounts paid by Buyer
pursuant to the terms of Sections 3.1(a) and (b) because the parties agree it
would be impracticable or extremely difficult to fix the actual damages
resulting from Buyer's termination or breach of this Agreement. The parties
agree that such sum or sums shall constitute liquidated damages intended to
reasonably and justly compensate Seller for such termination or breach and shall
be Seller's sole remedy and Buyer's sole liability or obligation to Seller for
any such breach or termination. Such liquidated amount shall be deemed full and
adequate damages for such termination or breach and is not intended by either
party to be a penalty. The liquidated damages provision of this Section 15.3
shall not apply to, or limit any damages arising out of, any breach of Section
7.1 or 10.1(d).

  16.      AUDIT RIGHTS.

regarding Earnout Payment or Exceeded Warranty under Sections 3.1(d) and 4.1
(d), respectively, Seller shall have the right to request, in writing, an audit
of Buyer's records, using Seller's employees or Seller's Auditor, with respect
to the determination of the Earnout Payment or Exceeded Warranty for the quarter
or quarters covered by the report and any prior quarters where audit rights may
be available and not waived hereunder; provided. however, that Seller shall be
entitled to only one audit of Buyer's records per calendar year pursuant to this
Section 16, which audit may cover only the most recent four quarters for which
reports have been rendered. If Seller does not notify

Buyer in writing before the lapse of such sixty (60) day period of Seller's
intent to request an audit by Seller's employees or Seller's Auditor, then
Seller will be deemed to have waived any claims or rights to audit Seller may
have regarding reports and amounts paid (or not paid) to Seller for any periods
which have been reported on and which precede the most recent four quarters for
which reports have been rendered. Upon such request for an audit being timely
made by Seller, Seller's employees or Seller's Auditor may, upon reasonable
notice, during normal business hours and at Seller's expense, inspect the
records of Buyer upon which such report is based, provided that each Seller's
employees or representative of Seller's Auditor first executes Buyer's standard
form of confidentiality agreement prior to undertaking such inspection. Upon
performing such audit, Seller through Seller's Auditor shall provide its
determination to both Buyer and Seller. If, after Seller's audit, Seller
disagrees with Buyer's calculation of either the Earnout Payment or the Exceeded
Warranty Amount, Seller shall deliver written notice to Buyer of its
disagreement as to Seller's calculation of the Earnout Payment or the Exceeded
Warranty Amount ("Audit Notice"). Any such Audit Notice shall specify in
reasonable detail the nature of such disagreement and the basis and supporting
evidence for Seller's position with respect to the disputed terms. Seller and
Buyer shall attempt in good faith to resolve any disagreement for a period of 30
days following the date of the Audit Notice and, if they are unable to do so
within such period, shall seek to resolve their dispute as provided in Section
14. If Buyer and Seller agree upon Seller's Auditor's determination or there is
a determination pursuant to Section 14 then if Buyer has underpaid Seller
pursuant to the applicable payment formula by geater than ten percent (10%) of
the amount actually due (as determined herein), then Buyer shall reimburse
Seller for all reasonable expenses and costs of such audit in addition to its
obligation to make full payment under Sections 3.1(d) and 4.1(b).
