Item 2.   DISPOSITION OF ASSETS

          On March 17, 1997, Wang Laboratories, Inc. (the "Company") completed
          the sale of its software business unit to Eastman Kodak Company
          ("Kodak") for $260.0 million in cash.  The business sold to Kodak
          includes Wang's software business unit management, employees,
          products, technology, customers, partners, as well as its sales,
          marketing and research and development organizations worldwide.  The
          consideration paid to the Company was determined through arms-length
          negotiations between the Company and Kodak.  The Company will record a
          nonrecurring gain in the quarter ending March 31, 1997, although the
          actual amount of the gain has not yet been determined.  A press
          release prepared by the Company is attached hereto as Exhibit 99.1 and
          a copy of the Asset Purchase Agreement, as amended, is attached hereto
          as Exhibit 10.1.  The foregoing description is qualified in its
          entirety by reference to the copy of the Asset Purchase Agreement.

Item 5.   OTHER INFORMATION

          In connection with the sale of the software business unit, the
          Company's Board of Directors completed its review of the Company's
          strategic focus, core competencies and key assets to compete
          successfully in the global information technology services market as a
          network and desktop integration and services company. This review
          included an evalution by the Board of Mr. Tucci's contributions to the
          Company as the leader and architect of its global strategy. The Board
          also assessed Mr. Tucci's leadership and vision in guiding the Company
          through its emergence from Chapter 11 and its transformation through a
          number of revenue-enhancing and value-building software and services
          acquisitions, culminating with the sale of the software business to
          Eastman Kodak Company.

          In acknowledgment of his accomplishments, and in recognition of his
          commitment to the Company, the Board has approved certain
          modifications to Mr. Tucci's employment agreement. These include an
          increase in annual base salary to $750,000, the grant of additional
          equity incentives in the form of both stock options and restricted
          stock grants and an immediate payment of a $4 million performance and
          retention bonus, all of which are intended to ensure Mr. Tucci's
          continued service to the Company. The enhancements set Mr. Tucci's
          base compensation at a level which is comparable to that of other CEOs
          in similar situations and more closely ties a majority of Mr. Tucci's
          future compensation to an increase in shareholder value. The last
          comprehensive restatement of Mr. Tucci's employment agreement occurred
          on March 9, 1993.

          A press release prepared by the Company is attached hereto as
          Exhibit 99.2.

                              FINANCIAL STATEMENTS


The Pro Forma Condensed Balance Sheet reflects the consolidated balance sheet of
the Company as of December 31, 1996 as if the sale of the Company's software
business unit to Kodak had been consummated on December 31, 1996.  The Pro Forma
Condensed Statements of Operations for the six months ended December 31, 1996
and each of the years ended June 30, 1996 and 1995 reflect the consolidated
results of operations of the Company as if the sale of the software business
unit had been consummated on July 1, 1994.  The Company intends to reclassify
the historical results of the software business unit to discontinued operations
in its consolidated statements of operations.  Pro forma results for the year
ended June 30, 1994 are not presented since the Company's operating results,
excluding those related to the software business unit, would not be materially
different than the results actually reported.

The pro forma information does not purport to be indicative of the financial
position or results of operations that would have been attained had the sale
occurred on the dates indicated nor of future results of operations of the
Company.  The pro forma condensed financial statements should be read in
conjunction with the separate unaudited and audited financial statements and
notes thereto of Wang Laboratories, Inc. included in its Quarterly Report on
Form 10-Q for the six months ended December 31, 1996 and its Annual Report on
Form 10-K for the year ended June 30, 1996.

(3) Statements of operations of the software business unit for the periods
    presented, which will be classified as discontinued operations as a result
    of the sale of the software business unit to Kodak.

(4) As a result of the Company's ability to utilize its available pre-
    confirmation net operating loss carryforwards to offset taxable income
    expected from this transaction, the anticipated provision for income taxes
    of $71.3 million consists of $4.2 million of cash expense and $67.1 million
    of non-cash expense. Under FASB 109, "Accounting for Income Taxes", the non-
    cash provision for income taxes is expected to eliminate the balance of the
    Company's remaining fresh-start intangible assets. The Pro Forma Condensed
    Statements of Operations do not reflect the reduction of the annual
    amortization expense of these assets expected as a result of this
    transaction. Amortization expense related to these assets amounted to $7.3
    million for the six months ended December 31, 1996 and $19.1 million for
    each of the years ended June 30, 1996 and 1995.

(5) The Pro Forma Statements of Operations do not reflect the reduction to
    interest expense due to the Company's anticipated repayment of its
    outstanding revolving credit facility or interest income on the cash
    generated from the sale.

              2.4.13 Any amounts due from an Acquired Subsidiary to Sellers and
         their Affiliates, all of which shall be settled prior to Closing as
         provided in Section 5.3; and

              2.4.14 Except for the W/I Payment to the extent provided in
         Section 6.23, any liability of Sellers to the other parties thereto
         arising from the Acquisition Agreements.

         2.5  Consideration. In consideration of Sellers' performance of this
Agreement and the transfer and delivery of the Purchased Assets to the Buyer
Purchasers, Buyer shall (in accordance with the allocation provided for in
Section 2.6) (a) deliver to Seller by wire transfer to the account which Seller
shall specify at least five business days prior to the Closing Date Two Hundred
Sixty Million Dollars ($260,000,000) (the "Cash Consideration") in immediately
available funds, less the amounts, if any, payable under clause (b) of this
Section (if any such amounts are payable other than in Dollars, the Dollar
equivalent of such amount based on the rate published in the Wall Street Journal
three (3) business days prior to Closing), (b) deliver the respective amounts
allocated pursuant to Section 2.6 by wire transfer to the Sellers outside the
U.S., where required by local Laws or to avoid payment of interest or Taxes
triggered by payments made outside of the jurisdiction where the Purchased
Assets are transferred; and (c) assume or cause Buyer Purchasers to assume the
Assumed Liabilities.

         2.6  Allocation of Consideration. For purposes of complying with the
requirements of Section 1060 of the Code, a schedule allocating the
Consideration to be paid by Buyer among the Sellers and among each class of
Purchased Assets (the "Purchase Price Allocation Schedule") shall, no later than
two weeks from the date of this Agreement, be prepared by Buyer with Seller's
assistance and provided to Seller for Seller's approval. Each of Sellers and
Buyers shall prepare its federal, state, local and foreign Income Tax returns
for all current and future tax reporting periods and file Form 8594 (and
corresponding state, local and foreign forms) with respect to the transfer of
the Purchased Assets to Buyers in a manner consistent with the Purchase Price
Allocation Schedule. If any Governmental Entity challenges such allocation, the
party first receiving notice of such challenge shall give the other party prompt
notice of such challenge, and the Seller and Buyer shall cooperate in good faith
in responding to such challenge, in order to preserve the effectiveness of the
Purchase Price Allocation Schedule. None of the Sellers nor the Buyers shall
report the allocation of the Consideration in a manner inconsistent with the
Purchase Price Allocation Schedule.

         2.7  Local Transactions. Annex 2.7 identifies the Buyer Purchaser, the
Selling Subsidiary, the type of purchase (stock or asset purchase) and other
terms and conditions with respect to closing of the sale and purchase of the
Business and Purchased Assets in each jurisdiction where Purchased Assets or
Employees are located or are to be located.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES
                              OF SELLER AND FEDERAL


         Seller and Federal, jointly and severally, represent and warrant to
Buyer, for themselves and on behalf of the other Sellers and the Acquired
Subsidiaries, that the statements contained in this Article III are true and
correct, except as set forth in the Disclosure Letter. The Disclosure Letter
shall be prepared by Seller and delivered to Buyer simultaneously with the
execution of this Agreement and shall be arranged in Schedules corresponding to
the numbered Sections contained in the Agreement. The disclosures in any
Schedule shall qualify any other Schedule or Section to the extent that it is
clear from a reading of such Schedule or Section that such disclosure is
applicable to such other Schedule or Section .

         3.1  Organization, Power, Standing and Qualification. Seller is a
corporation duly organized, validly existing, and in good standing under the
laws of the State of Delaware, and has all requisite corporate power and
authority to carry on its business as it is now being conducted and to own and
operate the properties and assets now owned and operated by it. The Sellers and
Acquired Subsidiaries have been duly organized and are validly existing and in
good standing in the jurisdiction of their organization (to the extent such
concepts are recognized in the jurisdiction of their organization). Each of the
Sellers and Acquired Subsidiaries has all requisite corporate or partnership, as
the case may be, power and authority to carry on its business as it is now being
conducted and to own and operate the properties and assets now owned and
operated by it. Seller has delivered to Buyer complete and correct copies of the
organizational documents of each of the Acquired Subsidiaries. Each of the
Sellers and Acquired Subsidiaries is duly qualified to do business and in good
standing in each jurisdiction (to the extent such concepts are recognized in the
jurisdiction of their organization) where the conduct of its business or the
ownership or operation of its assets requires such qualification except where
failure to be so qualified or in such good standing will not result in a
Material Adverse Effect on the Business or the Purchased Assets. All
jurisdictions in which the Acquired Subsidiaries are qualified to do business
are listed on Schedule 3.1. Seller has provided Buyer with copies of all minute
books, records of meetings and consents of the Boards of Directors,
stockholders, managers or other governing bodies of the Acquired Subsidiaries
and all stock (or other equity) transfer ledgers in its possession with respect
to each Acquired Subsidiary, each of which is correct and complete in all
material respects.

         3.2  Power and Authority. Upon execution and delivery as contemplated
herein, this Agreement will be a valid and binding obligation of Seller and
Federal, enforceable against each of them in accordance with its terms except to
the extent that its enforceability may be subject to applicable bankruptcy,
insolvency, reorganization, fraudulent conveyance, moratorium or similar Laws
affecting the enforcement of creditors' rights generally and to general
equitable 
<PAGE>
 
                                     - 18 -


principles. Seller and Federal each have all requisite corporate power and
authority to enter into this Agreement and to perform all of its obligations
hereunder. The Board of Directors of each of Seller and Federal has duly
authorized the execution and delivery of this Agreement and the performance of
the Transactions. No approval of the stockholders of Seller is required with
respect to the consummation of the Transactions.

         3.3  Validity of Contemplated Transactions. The execution, delivery and
performance of this Agreement by Seller and Federal, the execution, delivery and
performance by each of the Sellers of the Collateral Documents to which each is
a party and the consummation of the Transactions do not and will not (a)
contravene any provision of the Certificate of Incorporation or By-laws or the
organizational documents of any of the Sellers; (b) contravene any provision of
or constitute a breach or result in a Default under the Reorganization Plan; or
(c) constitute a breach by Sellers or the Acquired Subsidiaries of, or result in
a Default under or cause the acceleration of any payments pursuant to, any
agreement, contract, indenture, lease or mortgage to which any of the Sellers or
the Acquired Subsidiaries is a party or by which any of the Purchased Assets are
bound, or violate any provision of any Law or Permit to which the Sellers or the
Acquired Subsidiaries is subject, except for (i) requirements for consents of
Persons referred to in Section 3.4, and (ii) breaches, Defaults or accelerations
of agreements, contracts, indentures, leases or mortgages which, individually or
in the aggregate, would not have a Material Adverse Effect on the Business or
the Purchased Assets.

         3.4  Consents. No permit, consent, approval or authorization of, or
designation, declaration or filing with, any Governmental Entity or any other
Person on the part of any of the Sellers or any of the Acquired Subsidiaries is
required in connection with the execution or delivery by the Sellers of this
Agreement or the consummation of the Transactions other than (a) those which
have previously been obtained, (b) those specified in Schedule 3.4 and those
required under any Competition Laws, or (c) such permits, consents, approvals,
authorizations, designations, declarations or filings the absence of which,
individually or in the aggregate, would not materially impair the ability of the
Sellers to consummate the Transactions or have a Material Adverse Effect on the
Business or the Purchased Assets (taken as a whole).

         3.5  Acquired Subsidiaries. Other than the Acquired Subsidiaries,
Sellers have no equity ownership in any other Person conducting the Business or
owning any Purchased Assets. Schedule 3.5 lists all classes or series of capital
stock or other equity interests of the Acquired Subsidiaries authorized, issued
or outstanding. Except as set forth in Schedule 3.5, all of the issued and
outstanding shares of capital stock or other equity interests of each of the
Acquired Subsidiaries are owned by one or more of the Sellers or by directors as
qualifying shares as set forth on Schedule 3.5, free and clear of all liens,
encumbrances and transfer restrictions, and such stock and interests are validly
issued, fully paid and non-assessable. There are no outstanding rights of
subscription, warrants, calls, options, contracts or other similar agreements,
issued or granted by the Sellers or any of the Acquired Subsidiaries to any
third party, to purchase or 
<PAGE>
 
                                     - 19 -


otherwise acquire capital stock or other equity interests of any of the Acquired
Subsidiaries. All dividends and other distributions paid by the Acquired
Subsidiaries were duly and lawfully declared and paid in full and none of the
Acquired Subsidiaries has any unpaid note or other obligation with respect to
any such dividend or other distribution. Except as set forth in Schedule 3.5,
the Acquired Subsidiaries have not guaranteed, assumed or otherwise become
responsible for any liability or other obligation of the Sellers or any of their
Affiliates, and do not hold any equity interests in any Person. Schedule 3.5
sets forth for each country where there are Purchased Assets or Employees the
name of each of the Sellers and Acquired Subsidiaries owning such Purchased
Assets or employing such Employees.

         3.6  Financial Statements and Business Plan. (a) Schedule 3.6 contains
pro forma balance sheets and pro forma statements of operations and pro forma
cash flows for the Seller's software business unit for the three months ended
September 30 and December 31, 1996 and for the fiscal year ending June 30, 1996
(the "SBU Financial Statements"). The SBU Financial Statements have been derived
from the Sellers' and Acquired Subsidiaries' books and records maintained in the
ordinary course of business. Except as set forth in Schedule 3.6, the SBU
Financial Statements have been prepared as set forth in Annex 3.6 and fairly
present the financial position and results of operations of the Seller's
software business unit as at the dates and for the periods shown thereon. The
Pro Forma Balance Sheet at the Balance Sheet Date (the "12/31 Pro Forma Balance
Sheet") has been derived from the December 31, 1996 balance sheet included
within the SBU Financial Statements and reflects those of the Purchased Assets,
under the line items the "Accounts Receivable," "Inventories", "Prepaid
Expenses" and "Other Assets" (as described in the schedules to the 12/31 Pro
Forma Balance Sheet), of a nature required to be shown thereon for the Business.
The liabilities shown on the 12/31 Pro Forma Balance Sheet reflect none of the
Excluded Liabilities.

         (b)  Schedule 3.6 also contains projected cash flow statements and
other projected financial information for the Business for the fiscal years
ended June 30, 1997, 1998 and 1999, which form a portion of Seller's business
plan for the Business (the "Business Plan"). The Business Plan is the only
business plan being utilized by the Seller to operate the Business and to the
extent incentive compensation of the management of the Business is based upon
financial results of the Business such compensation is based upon performance
measured against the Business Plan. No representation or warranty is made herein
as to future achievement of the cash flows or other projected financial
information, or the achievement of financial performance levels, or the
introduction of products set forth in the Business Plan.

         3.7  Undisclosed Liabilities. Except (a) as reflected or reserved
against in the 12/31 Pro Forma Balance Sheet; (b) for liabilities incurred in
the ordinary course of business of the Business since September 30, 1996 to the
extent reflected on the 12/31 Pro Forma Balance Sheet or the Closing Pro Forma
Balance Sheet; (c) for liabilities not required to be disclosed on the 12/31 Pro
Forma Balance Sheet or the Closing Pro Forma Balance Sheet under GAAP; and (d)
as 
<PAGE>
 
                                     - 20 -


disclosed in Schedule 3.7, neither Sellers nor any of the Acquired Subsidiaries
has any liabilities or any obligations of any nature whether or not accrued,
contingent or otherwise, that are material individually (or in the aggregate, in
the case of a series of liabilities arising from the same event or set of facts)
or, in the case of liabilities related to the ownership or use of the Property
or the Employees, are material in the aggregate to the Business or the Purchased
Assets taken as a whole.

         3.8  Absence of Certain Changes. From September 30, 1996 to the date of
this Agreement, except as set forth on Schedule 3.8, the Sellers and the
Acquired Subsidiaries have operated the Business in the ordinary course and in a
manner consistent with past practice, and during such period, there has not
been:

              3.8.1 Any occurrence or event known to Seller which, individually
         or in the aggregate, has resulted in or which Seller reasonably expects
         will result in any Material Adverse Effect on the Business or the
         Purchased Assets (taken as a whole), except for changes or events
         resulting from (a) general economic conditions or (b) conditions that
         effect as a whole the industry of which the Business is a part and
         about which information is publicly available;

         the Permitted Encumbrances) on, any such asset, or any lease of
         property of the Business, including equipment, or any termination or
         surrender of any lease, right or franchise used in the Business or any
         action to windup or discontinue the Business in any jurisdiction where
         the Business is conducted;

              3.8.3 Other than in the ordinary course of business of the
         Business consistent with past practice and except as described in

              3.8.4 The discharge or satisfaction of any material lien or
         encumbrance or the payment of any material liability of the Sellers
         with respect to the Business or the Acquired Subsidiaries other than
         (a) as required by the terms thereof, or (b) in the ordinary course of
         business of the Business consistent with past practice;

              3.8.5 The making of any loan, advance or guaranty to or for the

         knowledge of Seller, there are no circumstances which would give rise
         to any termination, Default, cancellation or breach under, any Inbound
         Technology Agreement.

              3.10.7 Outbound Technology Agreements. Sellers and Acquired

         Sellers and the Acquired Subsidiaries have received no written notice
         of any claim, demand, suit or other assertion by any third party; and
         (b) to the knowledge of Sellers and the Acquired Subsidiaries, there
         are no circumstances which would (or are likely to) give rise to any
         claim, demand, suit or other assertion by any Person other than a party
         to this Agreement, that such Person has superior rights, ownership or
         shared ownership requiring any payments to any Person other than as
         provided in this Agreement, or other interest of any kind or nature in
         or with respect to, the IT Property or the IP Rights.

              3.10.10 No Government Funding. Except as set forth in Schedule

         technology or exploiting or marketing it in any manner.

              3.10.11 No Claims Against Contributors. To the Sellers' knowledge,
         no Person has claimed or has reason to claim that any Contributor, by
         virtue of its participation in the development of the IT Property or
         the IP Rights has thereby: (a) violated any of the terms or conditions
         of any employment, non-competition or non-disclosure agreement; (b)
         disclosed or utilized any trade secret or proprietary information or
         documentation in an unauthorized manner; (c) tortiously interfered with
         or breached any agreement; or (d) violated or exceeded the scope of any
         Law or agreement.

              3.10.12 Notices and Markings. Sellers and the Acquired
         Subsidiaries have taken all reasonable measures to protect the
         proprietary rights of Sellers and the Acquired Subsidiaries to the IT
         Property and the IP Rights therein. In no instance has the eligibility
         of the IT Property (excluding the portions licensed under the Inbound
         Technology Agreements) and the IP Rights therein for protection under
         applicable U.S. copyright Law been forfeited to the public domain by
         omission of any required notice or marking, or inclusion of any false
         marking or any other reason where such forfeiture would have a Material
         Adverse Effect on the Business.


              3.10.13 Noninfringement. Except as set forth in Schedule 3.26, the

                   (a) Infringe any copyright, or to the knowledge of Sellers,
         induce or contribute to the infringement of any copyright of any
         Person;

                   (b) To the knowledge of Sellers, infringe or induce or
         contribute to the infringement of any patent or intellectual property
         right (other than copyright) of any Person;

                   (c) To the knowledge of Sellers, misappropriate any Trade
         Secret, know-how, process, proprietary information or other right of

         the Acquired Subsidiaries has received notice of and none has any
         knowledge of any complaint, assertion, threat or allegation that would
         contradict the foregoing. For purposes of this Subsection 3.10.13,
         knowledge shall not be inferred solely because the claimant complied
         with patent marking requirements or statutory copyright notice
         provisions.

              3.10.14 Judgments and Settlements. Except as provided in Schedule
         3.26, the IT Property or IP Rights of the Sellers or the Acquired
         Subsidiaries or, to Seller's knowledge, the right of any third party
         licensor to the intellectual property licensed pursuant to the Inbound
         Technology Agreements, are not subject to any outstanding settlement
         agreement, order, ruling, decree, judgment, or stipulation preventing
         their use by Buyer Purchasers in the Business as currently conducted.

              3.10.15 Warranties and Warranty Claims. Other than as set forth in
         the Outbound Technology Agreements, the Project Agreements or the
         standard form of warranties set forth in Schedule 3.10.15, the Sellers
         and Acquired Subsidiaries have not made any written or other binding
         warranty or representation with respect to any of the Business
         Software, or any product that embodies or utilizes any of it or them.
         All pending warranty claims by Sellers' and the Acquired Subsidiaries'
         customers with respect to the Products are described on Schedule
         3.10.15. Seller has heretofore provided Buyer with access to a complete
         copy of all unresolved written customer complaints and all written
         summaries of those oral customer complaints in Sellers or the Acquired
         Subsidiaries' possession relating to the Products and any products not
         currently sold by the Business but as to which ongoing service or
         support is provided by the Business.

              3.10.16 Condition of the IT Property. The Documentation, Design
         Documentation and Support Collateral are sufficient and adequate to
         enable Buyer, using the Employees and reasonably skilled and trained
         personnel, to provide for the continued maintenance and support of the
         Business Software in connection with the conduct of the Business as
         presently conducted. The Sellers and the Acquired

         rendering the IT Property capable of operating accurately for Year 2000
         purposes; (c) completing development work committed as required under
         the Assigned Contracts; and (d) completing development work
         contemplated under the Business Plan; and except as set forth in Annex
         7.1.5, to the knowledge of Sellers and the Acquired Subsidiaries, such
         written management assessments have not materially changed as of the
         date of this Agreement.

              3.10.17 No Undocumented Controls. To the knowledge of Sellers and

         reflected in Design Documentation.

         of any Person which would interfere with such license.

         matter under this Section 5.2 and provide Seller with a response within
         48 hours after receiving all information reasonably required by the

         Seller to avoid breach of a specifically identified covenant made by
         Seller in Subsection 5.2.1 and is so required, Buyer shall not be
         entitled to treat such breach as a breach of the identified covenant.

or indirectly, any inquiries in respect of or the making of, any Acquisition
Offer (as defined below) or engage in any negotiations concerning or provide any

ordinary course of business) to any Person other than Buyer or for the sale or
exchange of any stock of any of Sellers or the Acquired Subsidiaries with or to
any third party, or the merger or amalgamation of any of the Sellers (other than

efforts to assist Seller in obtaining such consents and shall have the right, if
additional assurances with respect to the assumption of obligations by any Buyer

         Return) or refund claim, determining any Tax liability or a right to a
         refund, conducting or defending any audit or other proceeding in
         respect of Taxes or otherwise effectuating the terms of this Agreement.
         Notwithstanding the foregoing, neither Seller nor Buyer, nor any of
         their Affiliates, shall be required unreasonably to prepare any
         document, or determine any information not then in its possession, in
         response to a request under this Subsection 6.5.4; provided, however,
         no request shall be deemed unreasonable if made in response to the
         request of a taxing authority for information on documents not in the
         possession of the party receiving the request nor otherwise reasonably
         available to it. Nothing in this Subsection 6.5.4 shall limit (or be
         construed as limiting) the obligation of Seller to indemnify Buyer
         Indemnified Parties pursuant to Section 9.3.

         6.6  Confidentiality. Seller and Buyer acknowledge and confirm their
obligations under the letter agreement ("Letter Agreement"), dated July 17, 1996
as amended on September 27, 1996, and agree that except as expressly set forth
herein, such Letter Agreement continues in full force and effect. In addition to
the limitations set forth in the Letter Agreement, following the Closing Date,
Sellers shall, and shall use commercially reasonable efforts to cause their
personnel and agents to, hold in strict confidence, not disclose to any Person
without the prior written consent of Buyer, and not use in any manner
whatsoever, any confidential business or technical information remaining in
their possession concerning the Business or the Purchased Assets other than 
<PAGE>
 
                                     - 56 -


as contemplated in the Collateral Agreements. Such confidential information
specifically includes all source code, system and user documentation, and other
Documentation and Design Documentation pertaining to the Technology, including
any proposed design and specifications for future products and products in
development, marketing plans, and all other technical and business information
concerning the Business. Promptly following the Closing Date, Sellers shall
deliver to Buyer Purchasers all materials remaining in their possession
containing any such confidential information, including all copies, extracts,
adaptations, and transcriptions thereof.

         6.7  Notification of Certain Matters. Prior to the Closing, Sellers
shall give prompt notice to Buyer, and Buyer shall give prompt notice to Seller,
of any event, occurrence or circumstance which causes, or Seller or Buyer,
respectively, believes causes, (a) any representation of itself or the other, as
the case may be, contained in this Agreement to be untrue or inaccurate in any
material respect at the date of this Agreement or at the Closing, or (b) itself
or the other, as the case may be, to fail to comply with or satisfy any
covenant, condition or agreement to be satisfied or complied with by it other
than the covenant contained herein; provided, however, the delivery of any
notice under this Section 6.7 shall not constitute an admission of any breach
of, or failure to conform with, or a waiver by, the giver or recipient of any
representation, warranty, covenant, obligation or right, or otherwise limit its
remedies.

         6.8  Transfer Taxes. All excise, sales, use, transfer, stamp,
documentary, filing, recording and other similar taxes or fees which may be
imposed or assessed as the result of the Transactions ("Transfer Taxes"),
together with any interest or penalties with respect thereto shall be shared
equally by Seller and Buyer. All Tax Returns required to be filed in connection
with any Transfer Taxes shall be prepared and filed when due by the party
responsible under applicable Law or custom to file such Returns. The filing
party shall promptly provide the other applicable parties with copies of such
Returns. All Transfer Tax Returns shall be prepared on a basis consistent with
the Purchase Price Allocation Schedule. Within 45 days after the Closing Date
(or the closing in the applicable Deferred Country in the event of a staged
closing as provided in Section 8.3), Seller and Buyer shall provide notice to
each other of the Transfer Taxes paid by each and the party who has paid less
than one-half such Transfer Taxes shall promptly reimburse the other so that
each party bears one-half the expense of the Transfer Taxes.

         6.9  Section 338(h)(10) Election. Seller will cooperate with Buyers in
making an election pursuant to Code Section 338(h)(10) and elections, if
available, under comparable state statutes with respect to the purchase of the
stock of the Acquired Subsidiaries in Seller's consolidated U.S. federal income
tax return for the taxable period which includes the Closing Date.

         6.10 Transferred Employees.

              6.10.1 The applicable Buyer Purchaser shall offer employment to
         all Applicable Employees effective as of the Closing Date or upon the
         return of any such Applicable Employee to active employment, which
         offer shall contain a release by such Employees in substantially the
         form contained on Annex 6.10.1, or, if required by applicable Law,
         shall accept the transfer of employment of such Applicable Employees
         and the Acquired Subsidiaries shall continue to employ such Applicable
         Employees. "Applicable Employees" means all of the following:

                   (a)  All persons who are active Employees on the Closing 
              Date. Employees on temporary leave for purposes of jury or annual
              two-week national service/military duty shall be deemed to be
              active Employees;

                   (b)  Employees who on the Closing Date are on nonmedical 
              leave of absence; provided, however, that no such employee shall
              be guaranteed reinstatement to active service if his return to
              employment is contrary to the terms of his leave, unless otherwise
              required by applicable Law (for purposes of the foregoing,
              nonmedical leave of absence shall include maternity or paternity
              leave, leave under the Family and Medical Leave Act of 1993,
              educational leave, military leave with veteran's reemployment
              rights under federal law, or personal leave, unless any of such is
              determined to be a medical leave);

                   (c)  (i)  U.S. Employees other than Employees of Sigma who on
              the Closing Date are on disability or medical leave and for whom
              it has been 180 calendar days or less since their last day of
              active employment; provided, however, that no such Employee shall
              be guaranteed reinstatement to active service if he is incapable
              of working in accordance with the policies, practices and
              procedures of the such Employee's employer immediately prior to
              Closing; and

                        (ii) All Non-U.S. Employees unless otherwise prohibited
              by country and local Laws; and

                   (d)  Persons to whom any of Sellers, with respect to the
              Business, or the Acquired Subsidiaries have made written offers of
              employment consistent with Subsection 5.1.2 and who are listed on
              Schedule 6.10.1(d).

         Those Applicable Employees who accept such offers of employment
         effective as of the Closing Date (or such later date as to which
         closing occurs outside the U.S. as

         provided in Section 8.3), or whose employment is transferred by
         operation of Law and in the case of any Acquired Subsidiary, all
         Employees, shall be referred to herein as the "Transferred Employees";
         it being understood that each Employee, other than an Employee of an
         Acquired Subsidiary, on short-term disability (described in Subsection
         6.10.1(c)(i) above) who has accepted an offer of employment, shall
         participate in the applicable short-term disability plan of Seller or
         of an Acquired Subsidiary until such Employee returns from leave, and
         shall become a Transferred Employee only upon the termination of his or
         her leave. Buyer shall reimburse Seller for amounts paid under Sellers'
         short term disability plan to any such Employees who become Transferred
         Employees after the end of their short term disability for up to 180
         days' short term disability payments made by Sellers during the period
         from the Closing Date to the date such Employee becomes a Transferred
         Employee.

              6.10.2 Sellers shall notify and consult with the works councils or
         similar employee representatives as required by applicable Law with
         respect to the transfers contemplated by this Agreement. Sellers and
         Buyer Purchasers will cooperate with each other to determine the
         amounts of any and all retention, termination, change in control or
         other similar compensation or benefit payments which are or may become
         payable to any Employee in connection with the consummation of the
         Transaction which shall, to the extent so determined, be shared equally
         by Buyer and Seller.

              6.10.3 Seller shall allow Buyers to contact and make employment
         arrangements with the Employees conditioned upon consummation of the
         Transactions for the period following the Closing, and Seller expressly
         waives and releases any potential claims against Buyers and such
         Employees for their actions in making such arrangements other than
         actions which constitute violations of Law.

         6.11 Access to Certain Customers. Prior to the Closing or earlier
termination of this Agreement, Sellers shall use reasonable commercial efforts
to furnish Buyer's representatives with the opportunity to consult, together
with Seller's representatives, with the customers of the Business mutually
identified by Buyer and the Seller to assess the performance of the Business
with respect to its obligations to such customers and the future obligations or
opportunities with respect to such customer relationship.

         6.12 Office Space Arrangements.

              6.12.1 At Closing, Seller or the applicable Seller Subsidiary
         ("Sublandlord", and collectively, the "Sublandlords") and Buyer or the
         applicable Buyer Purchaser ("Subtenant", and collectively, the
         "Subtenants") shall enter into 
<PAGE>
 
                                     - 59 -


         the following subleases (the "Subleases"): (a) a sublease, in the form
         referred to on Annex 1.1 as the "Technology Park Sublease", pursuant to
         which Sublandlord will sublease to Subtenant certain space in the
         office building located at 600 Technology Park Drive, Billerica,
         Massachusetts; (b) a sublease, in form reasonably acceptable to both
         Seller and Buyer and containing the terms summarized in Annex
         6.12.1(b), pursuant to which Sublandlord will sublease to Subtenant
         certain space in the office building located at 7900 Westpark Avenue,
         McLean, Virginia; and (c) a sublease, in form reasonably acceptable to
         both Seller and Buyer and containing the terms summarized in Annex
         6.12.1(c), pursuant to which Sublandlord will sublease to Subtenant
         certain space in the office building located at 10 Place de la Coupole,
         Charenton, France. Sublandlord shall use reasonable efforts to obtain,
         prior to Closing, and shall deliver to Subtenant of Closing or at such
         later time that any such consent shall be obtained, if at all, all
         consents required to validly consummate the Subleases. Sublandlord
         shall be responsible for and shall promptly pay any and all costs
         associated with obtaining and delivering such consents, and Subtenant
         shall reasonably cooperate with Sublandlord in obtaining such consents,
         provided that Subtenant shall not be required to make any payment
         associated with obtaining such consent. The obtaining of such consents
         with respect to any particular Sublease shall not be a condition to
         Closing, but from and after the date of Closing, as provided in Article
         IX, Seller shall indemnify, defend and hold the Buyer Indemnified
         Parties harmless from and defend the Buyer Indemnified Parties, on an
         after-tax basis, from and against any and all Loss and Litigation
         Expense, which they or any of them may suffer or incur as a result of
         or arising from Seller's failure to seek or obtain the consent of the
         landlord, sublandlord or other party whose consent is required in
         connection with the making of the Sublease.

              6.12.2 At Closing, Seller or the applicable Seller Subsidiary
         ("Assignor", and collectively, the "Assignors") shall assign to Buyer
         or the applicable Buyer Purchaser ("Assignee", and collectively, the
         "Assignees") all of its right, title and interest in, to and under the
         Real Estate Leases listed on Annex 2.1.6, except for those Real Estate
         Leases so listed in which (as indicated on such Annex 2.1.6), the
         tenant is an Acquired Subsidiary (the "Acquired Subsidiary Leases"),
         and the applicable Assignee shall assume all obligations of the
         applicable Assignor under each Real Estate Lease to be assigned
         hereunder arising after Closing, pursuant to certain Lease Assignment
         and Assumption Agreements substantially in the form attached to Annex
         1.1 as the "Lease Assignments". Seller shall use reasonable efforts to
         obtain, prior to Closing, and shall deliver to Buyer at Closing or at
         such later time that any such consent shall be obtained, if at all, all
         consents required under Acquired Subsidiary Leases as a result of the
         transfer of the ownership interests in such Acquired Subsidiaries
         contemplated under this Agreement. Seller shall be responsible for and
         shall promptly pay any and all costs associated with 
<PAGE>
 
                                     - 60 -


         obtaining and delivering such consents, and Buyer shall reasonably
         cooperate with Seller in obtaining such consents, provided that neither
         Buyer nor any Buyer Purchaser shall be required to make any payment
         associated with obtaining such consent nor grant any guarantee of any
         obligation as a condition to obtaining such consent. The obtaining of
         such consents with respect to any particular Lease Assignment or deemed
         transfer of an Acquired Subsidiary Lease (a "Lease Transfer") shall not
         be a condition to Closing, but from and after the date of Closing, as
         provided in Article IX, Seller shall indemnify, defend and hold the
         Buyer Indemnified Parties harmless from and defend the Buyer
         Indemnified Parties, on an after-tax basis, from and against any and
         all Loss and Litigation Expense, which they or any of them may suffer
         or incur as a result of or arising from Seller's failure to seek or
         obtain the consent of the landlord, sublandlord or other party whose
         consent is required in connection with the making of the Lease
         Transfer.

              6.12.3 At Closing, Seller and Buyer shall enter into a Master
         Space Sharing Agreement, substantially in the form attached to Annex
         1.1 (the "Master Space Sharing Agreement"), relating to the spaces
         listed on Annex 6.12 (the "Shared Spaces"), pursuant to which, among
         other things, Seller shall grant to Buyer the right to use and occupy
         certain areas in the Shared Spaces in exchange for the payment of
         certain amounts and Buyer's assuming certain obligations with respect
         to such areas. Any consents to the Master Space Sharing Agreement which
         may be required to be obtained under any of the Real Estate Leases
         shall not be a condition to Closing, and neither Seller nor Buyer shall
         seek to obtain such consents.

              6.12.4 With respect to the Acquired Subsidiary Lease of premises
         located in Solna, Sweden (the "Sweden Lease"), Seller covenants and
         agrees that the rent payable by the applicable Acquired Subsidiary
         under the Sweden Lease shall not exceed the fair market rental value
         therefor, determined in the manner described in Annex 6.12.4 (the "Fair
         Market Rental"), of the premises leased under the Sweden Lease (the
         "Sweden Premises"). If the Fair Market Rental is less than the rent
         payable under the Sweden Lease, Seller shall, at Seller's option, no
         less than thirty (30) days after the final determination of the Fair
         Market Rental, either (a) enter into an agreement with the landlord
         under the Sweden Lease pursuant to which, at no cost to Buyer or the
         applicable Acquired Subsidiary, the Sweden Lease shall be modified to
         provide that the rent payable thereunder from and after the date of
         Closing shall equal the Fair Market Rental, or (b) pay to the Acquired
         Subsidiary on a monthly basis (retroactive to the date of Closing, if
         Fair Market Value is determined after the date of Closing) an amount
         equal to the amount by which each monthly installment of rent payable
         under the Sweden Lease exceeds the monthly Fair Market Rental for the
         Sweden Premises.

         6.13 Reorganization in France. Buyer and Seller shall, and shall cause
their respective Affiliates to, cooperate in the reorganization of the Business
in France so that such Business will be transferred to a yet to be organized
wholly owned subsidiary of Wang France, S.A. prior to the closing of
Transactions in France as set forth on Annex 2.7.

         6.14 Certain Transition Agreements. Buyer and Seller have entered into
a letter agreement dated the date of this Agreement with respect to (a) certain
transition services to be provided by Sellers after Closing to Buyer Purchasers
and the Acquired Subsidiaries referred to on Annex 1.1 as the Services
Agreement, and (b) the duplication and distribution of software at Sellers'
facilities in Tewksbury, Massachusetts and Limerick, Ireland referred to on
Annex 1.1 as the SDC Services Agreement. Prior to the Closing Date, Seller and
Buyer shall negotiate definitive forms of the Services Agreement, and the SDC
Agreement containing the substantive provisions outlined with respect thereto in
the letter agreement with such other terms and conditions as may be agreed to by
the parties, provided, however, that in the event such agreements cannot, using
commercially reasonable efforts by Buyer and Seller, be executed on or before
the Closing Date, the parties shall continue to operate under the letter
agreements and to cooperate in good faith to reach definitive agreements as soon
as possible.

         6.15 Retention Payments. Seller shall from time to time after the
Closing Date reimburse Buyer for one-half of the payments made to Employees
pursuant to the retention plan which Buyer has heretofore provided to Seller up
to a maximum reimbursement of $5,000,000.

         6.16 Employee Benefits.

              6.16.1 Buyer Purchasers will provide each Transferred Employee
         with benefits that, in the aggregate, are comparable to those in effect
         on the Closing Date; provided, however, that none of Buyer or Buyer
         Purchasers will have any obligation to establish any defined benefit
         pension plan or post-retirement benefit plan, or to accept any transfer
         of assets from any retirement plan of Sellers or an Acquired Subsidiary
         (except to the extent a Non-U.S. Benefit Plan is required to be assumed
         under Law). With respect to U.S. Transferred Employees, Buyer will
         cause any Internal Revenue Code section 401(k) plan established for
         such Employees to accept roll-ins of distributions received from any
         similar plan of Seller or an Acquired Subsidiary that is in existence
         on the Closing Date.

              6.16.2 Seller shall retain responsibility for providing group
         health coverage required by Section 4980B of the Code ("Continuation
         Coverage") to those Employees who do not accept employment with Buyer
         Purchasers and who elected to purchase such Continuation Coverage prior
         to the Closing Date (other than 
<PAGE>
 
                                     - 62 -


         Employees of Sigma, who shall continue to be the responsibility of
         Sigma). Buyer shall provide Continuation Coverage to such Transferred
         Employees in the U.S. or their dependents only (other than Employees of
         Sigma) with respect to "qualifying events" as defined in Code Section
         4980B(f)(3) which occur on and after the Closing Date, to the extent
         required by Law.

              6.16.3 Reserved.

              6.16.4 Pension liabilities and pension assets of the defined
         benefit plan in the Netherlands shall be transferred in bulk to the
         applicable Buyer Purchaser on the following basis:

                   (a)  the value of the pension assets to be transferred will
                        in total amount to no less than the value of 50% of the
                        sum of the accrued and projected benefit obligations
                        accepted by the applicable Buyer Purchaser in respect of
                        the transferred pension liabilities, as determined by
                        FAS 87 valuation methodology,

                   (b)  the underlying assumptions to be used in the calculation
                        of the accrued and projected benefit obligations will
                        be:

                        (i)   salary growth at a rate equal to current annual 
                              local inflation;

                        (ii)  discount rate and investment return equal to 
                              triple A-rated (or comparable) long term local
                              bond yields;

                        (iii) turnover rate used by Seller's actuary for the 
                              most recent valuation of liabilities; and

                        (iv)  mortality at the same levels as latest valuation
                              of such Plan.

                   (c)  Buyer and Seller shall mutually agree upon the kind of
                        assets to be transferred, which agreement shall not be
                        unreasonably withheld by the other party.

                   (d)  Payment of transfer values shall be made within one
                        month after the Closing Date and, if not so made, will
                        be increased by interest at a rate equal to that in
                        Section 6.16.4(b)(ii) per

                        annum for the period between the Closing Date and the
                        payment.

              6.16.5 Seller's shall cause the benefits of all Transferred
              Employees under non-U.S. defined contribution plans to be fully
              vested as of the Closing Date.

         6.17 Cooperation Regarding Audits, Litigation and Former Employees.

              6.17.1 Upon reasonable prior written request given by Buyer to
         Seller, Seller shall and shall cause its Affiliates to make available
         to Buyer and its representatives the facilities, books and records of
         Sellers, including the work papers of employees and accountants of
         Sellers, as are reasonably necessary for Buyer's accountants to audit
         the Business for the five-year period ending December 31, 1996,
         provided that such Persons do not unreasonably interfere with Sellers
         business and subject to appropriate confidentiality agreements with
         respect to any information not related to the Business.

              6.17.2 Upon reasonable prior written notice given by Buyer to
         Seller or Seller to Buyer, as the case may be, each party shall provide
         the other with access to such information and employees as either party
         may reasonably request in connection with any actions, suits or
         proceedings relating to the Business or the Retained Claims, provided,
         however, that the requesting party shall reimburse the party providing
         the access for its out-of-pocket costs of providing the information and
         direct salary costs for employees so requested.

              6.17.3 After the Closing Date, none of Buyers, Buyer Purchasers or
         their Affiliates or the Acquired Subsidiaries shall waive any release
         or covenant of confidentiality or non-disparagement in any Employment
         Agreement that benefits Seller or its Affiliates without the prior
         written consent of Seller and, at Seller's request and expense, assist
         Seller the enforcement of such. After the Closing Date, none of Sellers
         or their Affiliates shall waive any release, covenant of
         confidentiality or non-disparagement, assignment of intellectual
         property rights or other rights in any Employment Agreement that
         benefits the Business with the written consent of Buyer, and at Buyer's
         request and expense, will assist Buyer in the enforcement of such
         rights.

         6.18 Insurance Claims. After the Closing Date, Seller and Buyers shall
cooperate with Seller's insurers in processing all claims arising with respect
to acts, omissions, or occurrences prior to the Closing Date and shall cooperate
with Buyers' insurers in processing all claims with respect to acts, omissions,
or occurrences after the Closing Date.

         6.19 Additional Assurances. After the Closing Date, Seller shall and
shall cause its Affiliates to take such additional actions and execute any such
additional documents and instruments as may be reasonably necessary to fully
vest the Sellers' and Acquired Subsidiaries' ownership, rights and privileges in
the Purchased Assets in Buyers, provided, however, that in the event such
actions requested by Buyer were not reasonably necessary to effectuate the
Transactions, Buyer shall pay all of Seller's reasonable out-of-pocket costs
incurred in connection therewith. Notwithstanding anything to the contrary
contained in this Agreement, to the extent that the sale, assignment, transfer,
conveyance or delivery or attempted sale, assignment, transfer, conveyance or
delivery to Purchaser of any Purchased Asset is prohibited by any applicable Law
or would require any Governmental Entity or other third party authorizations,
approvals, consents or waivers and such authorizations, approvals, consents or
waivers shall not have been obtained prior to the Closing and Buyer shall have
waived the applicable condition to Closing with respect to such item(s), this
Agreement shall not constitute a sale, assignment, transfer, conveyance or
delivery, or any attempted sale, assignment, transfer, conveyance or delivery,
thereof. Following the Closing, the parties shall use reasonable efforts and
shall cooperate with each other, to obtain promptly such authorizations,
approvals, consents or waivers. Pending such authorization, approval, consent or
waiver, the parties shall cooperate with each other in any reasonable and lawful
arrangements designed to provide to Buyer the benefits and liabilities of use of
such Purchased Asset. Once such authorization, approval, consent or waiver for
the sale, assignment, transfer, conveyance or delivery of a Purchased Asset not
sold, assigned, transferred, conveyed or delivered at the Closing is obtained,
Seller shall and shall cause its Affiliates to promptly assign, transfer, convey
and deliver, or cause to be assigned, transferred, conveyed and delivered, such
Purchased Asset to Buyer for no additional consideration. To the extent that any
such Purchased Asset cannot be transferred or the full benefits and liabilities
of use of any such Purchased Asset cannot be provided to Buyer following the
Closing pursuant to this Section 6.19, then Buyer and Sellers shall enter into
such arrangements (including subleasing or subcontracting if permitted) designed
to provide to Buyers the economic and operational equivalent of obtaining such
authorization, approval, consent or waiver and the performance by Buyer of the
obligations thereunder to the extent permitted by Law.

         6.20 Use of Corporate Names. Except as set forth in this section,
Buyers shall not have any rights to use the Corporate Names. Effective as of the
Closing Date, Seller grants Buyer Purchasers and the Acquired Subsidiaries a
fully-paid, royalty-free, nonexclusive, worldwide license to use the Corporate
Names in connection with the conduct of the Business after Closing by the Buyer
Purchasers as follows:

         (a)  For a period of nine months after the Closing, Buyer Purchasers
              and the Acquired Subsidiaries may continue to use the Corporate
              Names in on- screen displays of versions of Product in existence
              as of Closing, whether 
<PAGE>
 
                                     - 65 -


              Product is produced before or after Closing, provided, however,
              that if the display is controlled by another Person not affiliated
              with Buyers, Buyer Purchasers and the Acquired Subsidiaries may
              continue to use the Corporate Names in such displays until they
              can be removed using commercially reasonable efforts.

         (b)  For a period of nine months after the Closing Date or the next
              commercial release of the applicable Product, whichever is
              earlier, Buyer Purchasers and the Acquired Subsidiaries may
              continue to use the Corporate Names on labels, packaging materials
              and promotional materials in existence as of the Closing Date. In
              addition, for a period of three months after Closing, Buyer
              Purchasers and the Acquired Subsidiaries may reprint such
              materials marked with the Corporate Names, if inventory existing
              as of Closing is insufficient to meet the needs of Buyer
              Purchasers and the Acquired Subsidiaries. Buyer Purchasers and the
              Acquired Subsidiaries may apply labels and packaging materials
              bearing the Corporate Names only to versions of Product in
              existence as of the Closing, whether Product was produced before
              or after the Closing. Where practicable, Buyer Purchasers and the
              Acquired Subsidiaries will oversticker the materials with the
              appropriate new corporate name and address or accompany shipments
              with a notice reflecting such new name and address.

         (c)  For a period of six months after the Closing, Buyer Purchasers and
              the Acquired Subsidiaries may continue to use the Corporate Names
              on signage, and on invoices and preprinted business forms in
              existence as of the Closing, provided that (i) if any business
              forms require a signature, each Buyer Purchaser shall sign such
              forms in its own name, and (ii) where practicable, Buyer
              Purchasers will oversticker invoices and forms with the
              appropriate new corporate name and address.

         (d)  All products and services of Buyers or the Acquired Subsidiaries
              which bear a Corporate Name of Seller pursuant to this Section
              6.20 shall comply with the quality standards of Seller and be of a
              quality at least equal to the quality of such products or services
              as distributed or provided by Sellers or the Acquired Subsidiaries
              immediately prior to the Closing Date.

         6.21 Subsidiary Names. No later than 90 days after the Closing, Buyer
shall cause the name of any Acquired Subsidiary that includes the Corporate Name
in its name, to exclude the Corporate Name. In the interim, Sellers grant to the
Acquired Subsidiaries a license to use the Corporate Names in the same manner
and on the same materials used by them before Closing, except that where
practicable, each Acquired Subsidiary will 
<PAGE>
 
                                     - 66 -


oversticker material bearing a Corporate Name to indicate the new name of each
Acquired Subsidiary or indicating that the Acquired Subsidiary is now owned by
the Buyer Purchaser.

         6.22 Use of the OPEN/image and PACE Trademarks. Seller shall retain
ownership of the OPEN/image and PACE trademarks, including all rights and
liabilities related thereto. Seller grants to Buyer Purchasers and the Acquired
Subsidiaries a license for the period extending until six months after Closing,
pursuant to which they may continue to use the OPEN/image and PACE trademarks on
Products known by those trade names as of Closing, and on related materials
bearing that mark, whether produced before or after Closing. In the event Buyer
Purchasers are required, in connection with the settlement or other resolution
of pending litigation by Seller or otherwise (including any action or proceeding
against Buyers) to discontinue their use of the OPEN/image trade mark prior to
the expiration of the six-month period, Seller shall reimburse Buyer Purchasers
for any additional expenses they reasonably incur solely as a result of
accelerating the change of product name or in defending action or proceeding
seeking to prevent a Buyer Purchaser from using the OPEN/image trademark prior
to the expiration of such six-month period.

         6.23 W/I Payments. In the event that Buyer or any Buyer Purchaser is
required to make any W/I Payment, Seller shall reimburse Buyer or such Buyer
Purchaser for that portion of the W/I Payment determined by multiplying the W/I
Payment by a fraction, the numerator of which is (x) the W/I Revenue from July
1, 1996 to and including the Closing Date, and the denominator of which is (y)
the W/I Revenue from July 1, 1996 to and including June 30, 1997.

         6.24 Removal of Sigma "Triangle." Buyer and the Buyer Purchasers shall
not produce any new documentation, or marketing, collateral and/or sales
materials after the Closing Date that include references to the Sigma Triangle
mark, and shall use all commercially reasonable efforts to delete all references
to the Sigma Triangle mark known to Buyer in all existing documentation and all
marketing, collateral and/or sales materials within 90 days after the Closing
Date.

         6.25 Post-Closing Conduct of Business. Following the Closing, Buyers
shall not, without the prior written consent of Seller, fail to continue the
conduct of the Business as a result of any threatened or pending litigation or
claims for which Seller shall have indemnification obligations under clause (f)
of Section 9.2.

         8.3  Staged Closings. Notwithstanding anything to the contrary
contained in Articles VII or VIII herein, in the event that any condition to the
closing set forth in Section 7.1 has not been satisfied with respect to any
country other than the U.S. and the U.K., (a) the Closing shall be effected;
provided, however, that (i) Buyer or the applicable Buyer Purchaser shall have
the option of deferring closing in any country with respect to which any
condition set forth in Subsections 7.1.2, 7.1.3, 7.1.4, 7.1.11, 7.1.12, 7.1.13
or 7.1.14 has not been satisfied as of such time (the "Deferred Countries"), and
(ii) the certificates to be delivered pursuant to Section 7.1 need only be true
as to countries in which Closing occurs on the Closing Date; (b) each subsequent
closing shall occur as soon as practicable following satisfaction of all
conditions with respect to each Deferred Country; and (c) pending closing with
respect to any Deferred Country, Sellers shall, with any necessary cooperation
from Buyer and the applicable Buyer Purchaser, operate the Business for the
account of Buyer under the Services Agreement. In connection therewith, (x)
Buyer shall or shall cause its designee to reimburse the applicable Seller on a
monthly basis as invoiced (with appropriate documentation) by Sellers for the
after-tax cash requirements, if any, for the portion of the Business as operated
in such Deferred Countries and the applicable Seller shall deliver to the
applicable Buyer Purchaser the after tax cash benefit, if any, derived from the
Business as operated in such Deferred Country; and at or within 30 days
following closing in any Deferred Country, Sellers shall pay to Buyer, or Buyer
shall pay to Seller, as the case may be, and shall deliver appropriate
documentation with respect any other contribution made by or received by the
respective Sellers by the Business as operated in the Deferred Country so that,
as between Sellers and Buyers, the operations shall have been for the account of
the applicable Buyer Purchaser on an after-tax basis; (y) the Employees shall
continue to be regarded as employees of the applicable Seller and any provisions
set forth in Section 6.10 shall be deemed to apply to the Employees only as of
the date the closing is effected in the applicable Deferred Country; and (z) the
parties shall use their reasonable best efforts, and cooperate with each other,
to satisfy promptly the applicable conditions.

         To the extent a Buyer Purchaser must, under applicable Law, pay cash
consideration for the Purchased Assets located in a Deferred Country at a
subsequent closing, Seller shall remit to Buyer, in immediately available funds,
the amount of cash consideration allocated to such Deferred Country in
accordance with Section 2.6 and 
<PAGE>
 
                                     - 74 -


previously paid at the Closing and the Buyer Purchaser shall pay such
consideration to the appropriate Sellers at such subsequent closing. In the
event that Buyer so requests, Seller shall remit to Buyer or a Buyer Purchaser,
in conjunction with any subsequent closing with respect to a Deferred Country,
in immediately available funds, the amount of Purchase Price allocated to such
Deferred Country in accordance with Section 2.6 and previously paid at the
Closing against payment of such amount in the local currency by the Buyer
Purchaser in such Deferred Country, the local currency equivalent to such amount
(based on the rate published in the Wall Street Journal three (3) business days
prior to Closing in such Deferred Country); provided, however, that Buyer shall
only make a request if the Laws of the Deferred Country prohibit the payment of
funds in Dollars.

         In the event a subsequent closing does not occur in any Deferred
Country by the date which is the six-month anniversary of the Closing Date,
Buyer or Seller may upon 30 days' prior written notice to the other, elect not
to purchase or sell the Transferred Assets and transfer or assume the Assumed
Liabilities in any Deferred Country. Buyer and Seller shall share equally any
out of pocket costs (including payments to non-employee attorneys, accountants
or other advisors, termination or similar payments to employees required by Law
or works councils, ongoing lease expenses or termination payments, filing fees
or similar costs) to terminate the Business in such Deferred Country.


                                   ARTICLE IX

                          SURVIVAL AND INDEMNIFICATION

         9.1  Survival of Representations, Warranties and Covenants. The
representations and warranties of the parties contained in this Agreement shall,

Seller and Federal set forth in Sections 3.1, 3.2, 3.3, 3.4 (as to consent of
Governmental Entities), 3.5, 3.14 (as to title only), 3.32 shall have no
expiration date; the representations and warranties in Section 3.29 shall
survive until 90 days after the statute of limitations has expired for any Taxes
due for periods prior to the Closing Date; the representations and warranties in
Sections 3.25 and 3.30 shall survive until 60 days after the applicable statute

ERISA or the Code; the representations and warranties in Sections 3.10 , 3.11,
3.12, and 3.13 shall survive for three years and the remaining representations
and warranties of Seller and Federal shall survive until the day corresponding

                                     - 75 -


the remaining representations and warranties of Buyer shall survive until the
day corresponding for the Closing Date occurring in the 18th month following
Closing Date, provided, however, that representations and warranties with
respect to any Deferred Country shall expire on the later of the corresponding
date occurring in the 18th month following the Closing Date or the corresponding
date in the 12th month following the date of the closing in the Deferred
Country. In the event notice of any claim for indemnification under Section 9.5
shall have been given prior to midnight on the last day of the applicable
survival period (the "Expiration Date"), the representations and warranties that
are the subject of such indemnification claim shall survive until the claim is
finally resolved. The covenants and agreements of the parties contained in this
Agreement shall survive until fully performed.

         9.2  Indemnification by Seller. To the extent set forth in Section 9.4
and in the manner herein provided, from and after the Closing Date, Seller shall
indemnify and hold harmless Buyer and its Affiliates, and their respective
employees, directors, agents and representatives (collectively, the "Buyer
Indemnified Parties"), on an after-tax basis, from and against any and all Loss
and Litigation Expense, which they or any of them may suffer or incur as a
result of or arising from any of the following: (a) any misrepresentation or
breach of warranty (determined without regard to any materiality qualification
contained in any representation or warranty except for those (i) contained in
Sections 3.8.1, 3.10.4, 3.10.6 or 3.10.16 or (ii) that are used to modify an
affirmative obligation to disclose on a schedule matters in circumstances where
the inclusion of materiality is necessary to give the sentence its intended
meaning), (b) the failure of Seller or its Affiliates to obtain all consents
designated on Annex 7.1.4(b) as provided in Section 5.5, (c) the failure by
Seller to satisfy any liability or obligation which is an Excluded Liability, or
(d) the failure of Seller or its Affiliates to pay any Transfer Taxes which the
Seller is required to pay pursuant to Section 6.8 or any other costs or expenses
which are the responsibility of Sellers; (e) any costs or expenses incurred in
defending, and all interest or penalties assessed, in claims challenging the
method of computing the W/I Payment used by Sellers prior to the Closing Date;
and (f) in the event that Buyer waives the condition to obtain the consents set
forth on Annex 7.1.4(a) as provided in Section 7.1.4(a), the failure by Seller
to obtain all consents listed on Annex 7.1.4(a), which shall not be subject to
any limitations described in Section 9.4 or Section 9.7.

         9.3  Indemnification by Buyer. To the extent set forth in Section 9.4
and in the manner herein provided, from and after the Closing Date, Buyer shall
indemnify and hold harmless Seller, its Affiliates and their respective
employees, directors, agents and representatives (collectively, the "Seller
Indemnified Parties"), on an after-tax basis, from and against any and all Loss
and Litigation Expense which they, or any of them, may suffer or incur as a
result of or arising from any of the following: (a) any misrepresentation or
breach of warranty (determined without regard to any materiality qualification
contained in 
<PAGE>
 
                                     - 76 -


any representation or warranty), (b) the failure by the Buyer or any Buyer
Purchaser to satisfy any liability or obligation which is an Assumed Liability,
(c) the failure of Buyers to pay any Transfer Taxes which the Buyer is required
to pay pursuant to Section 6.8 or any other costs or expenses which are the
responsibility of Buyers, (d) the conduct of the Business after the Closing Date
by Buyer Purchasers other than Loss and Litigation Expense for which Seller is
obligated to indemnify Buyer Indemnified Parties pursuant to Section 9.2, or (e)
the destruction of, or failure of Buyer to provide Seller within a reasonable
period of time after Seller's request, any books or documents in Buyer's
possession which are related to the Business prior to Closing and are reasonably
required by any Seller Indemnified Party in order to defend itself in any
Tax-related audit, assessment, suit or other legal or administrative proceeding.

         9.4  Certain Limitations on Indemnities.

              9.4.1 Except for indemnification obligations under clauses (c),
         (d), (e) and (f) of Section 9.2, Seller and Federal shall not have any
         obligation to indemnify Buyer Indemnified Parties unless (a) the
         aggregate of all such claims for breaches of representations,
         warranties or covenants other than the representations and warranties
         made in Sections 3.10, 3.11, 3.12 and 3.13 exceeds One Million Dollars
         ($1,000,000) and then only to the extent of such excess up to a maximum
         aggregate indemnity for such Loss and Litigation Expenses of
         Ninety-Five Million Dollars ($95,000,000), or (b) with respect to
         representations and warranties in Sections 3.10, 3.11, 3.12 and 3.13,
         the aggregate of all such claims for breaches of such representations,
         warranties and covenants exceeds Two Million Dollars ($2,000,000) up to
         a maximum aggregate indemnity limit for such Loss and Litigation
         Expenses of One Hundred Million Dollars ($100,000,000), provided,
         however that Seller shall also indemnify Buyer Indemnified Parties for
         one-half of all Loss and Litigation Expenses up to such $2,000,000
         threshold (the "Shared Threshold Claims").

              9.4.2 Except for indemnification obligations under clauses (b),
         (c) and (d) of Section 9.3, Buyer shall not have any obligation to
         indemnify Seller Indemnified Parties unless the aggregate of all such
         claims for breaches of representations, warranties or covenants exceeds
         One Million Dollars ($1,000,000) and then only to the extent of such
         excess up to a maximum aggregate indemnity limit for such Loss and
         Litigation Expenses of Ninety-Five Million Dollars ($95,000,000).

              9.4.3 The indemnifying party under Sections 9.2 and 9.3 shall not
         be liable to any Indemnified Party with respect to any occurrence,
         event, circumstance, act or omission unless such matter or a series of
         related matters arising from the same occurrence, event, circumstance,
         act or omission or similar conduct by the same 
<PAGE>
 
                                     - 77 -


         individual which causes a representation or warranty to be breached and
         which, results in Loss or Litigation Expense of $25,000 or more.

         9.5  Procedure. Promptly after acquiring knowledge of any Loss, or any
action, suit, investigation, proceeding, demand, assessment, audit, judgment, or
claim ("Claim") which may result in a Loss, and prior to the Expiration Date,
the Person seeking indemnity under this Article IX (the "Indemnitee") shall give
written notice thereof to the party from whom indemnity is sought (the
"Indemnitor"). The Indemnitor shall have the right, at its expense, to defend,
contest or compromise such Claim, through counsel of its choice (unless such
Indemnitor is relieved of its liability hereunder with respect to such Claim and
Loss and Litigation Expense by the Indemnitee) and shall not then be liable for
fees or expenses of the Indemnitee's attorneys (unless the Indemnitor and
Indemnitee are parties to the action and there exists a conflict of interest
between the Indemnitor and the Indemnitee, in which event the Indemnitor will be
responsible for the reasonable fees and expenses of one firm), and the
Indemnitee and the Indemnitor shall provide to each other all necessary and
reasonable cooperation in the defense of all Claims, including Shared Threshold
claims, including, but not limited to, the services of employees who are
familiar with the transactions out of which such Claim or Loss may have arisen.
In the event that the Indemnitor shall undertake to compromise or defend any
Claim, it shall promptly notify the Indemnitee of its intention to do so. In the
event that the Indemnitor, after written notice from Indemnitee, fails to take
timely action to defend the same, the Indemnitee shall have the right to defend
the same by counsel of its own choosing, but at the cost and expense of the
Indemnitor, provided, no settlement of a Claim, other than a Shared Threshold
Claim (to the extent that the Indemnitor and Indemnitee pay equal amounts), by
Indemnitee shall be effected without the consent of the Indemnitor unless
Indemnitee waives any right to indemnification therefor. The Indemnitor may
settle or compromise any action or consent to the entry of any judgment (i)
which includes the unconditional release by the Person asserting the Claim and
any related claimants of Indemnitee from all liability with respect to such
Claim in form and substance reasonably satisfactory to Indemnitee, and (ii)
which would not adversely affect the right of Indemnitee and its Affiliates to
own, hold use and operate their respective assets and businesses. Sellers and
Buyers shall treat any payment under this Article IX for all Tax purposes as an
adjustment of the Consideration, except to the extent such treatment is not
permitted under applicable Law.

         9.6  No Subrogation. If any payment is made by or Claim asserted
against Sellers under the terms of this Article IX, none of the Seller
Indemnified Parties shall have any rights against the Purchased Assets or any of
the Acquired Subsidiaries or any former officer or employee of any Acquired
Subsidiary or any Sellers who becomes an employee of any Buyer Purchaser or the
Acquired Subsidiaries, whether by reason of contribution, indemnification or
otherwise and shall not take any action against the Purchased Assets or the
Acquired Subsidiaries or any such officer or employee of any Buyer Purchaser or
any
<PAGE>
 
                                     - 78 -


Acquired Subsidiary with respect thereto. Any rights which the Seller
Indemnified Parties may have, by operation of law or otherwise against such
officers or employees, the Purchased Assets or the Acquired Subsidiaries are,
effective on the Closing Date, hereby expressly and knowingly waived.

         9.7  No Consequential Damages. EXCEPT AS SET FORTH IN SECTION 9.2(f),
NEITHER ANY PARTY TO THIS AGREEMENT NOR THEIR AFFILIATES SHALL BE LIABLE FOR
INCIDENTAL OR CONSEQUENTIAL DAMAGES SUFFERED BY A PARTY OR ITS AFFILIATES WITH
RESPECT TO ANY TERM OR THE SUBJECT MATTER OF THIS AGREEMENT PROVIDED, HOWEVER,
THAT THIS WAIVER SHALL NOT LIMIT ANY LIABILITY OF ANY PARTY TO INDEMNIFY THE
APPLICABLE INDEMNIFIED PARTIES FOR LOSS ARISING FROM DAMAGES OF SUCH TYPE THE
INDEMNIFIED PARTY IS REQUIRED TO PAY TO ANY OTHER PERSON.

         9.8  Exclusive Remedy. If the Closing occurs, the exclusive remedies
for any breach of any representation, warranty, covenant or agreement hereunder
shall be the indemnification provided by this Article IX and the rights provided
Buyers under Sections 6.12 and 8.3, and each party expressly waives any other
rights or remedies it may have, provided, however, that equitable relief,
including the remedies of specific performance and injunction, shall be
available with respect to any actual or attempted breach of this Agreement
occurring before the Closing Date or with respect to the breach of any covenant
to be performed after the Closing Date.


                                    ARTICLE X

of breach by Buyer, or Buyer in the case of breach by Seller, shall, within ten
days after receipt of reasonably satisfactory documentation of such costs, pay
all reasonable out-of-pocket fees and expenses (for non-employee attorneys,
accountants, investment bankers and similar persons, filing fees, etc.) incurred
by the other party in connection with the Transactions.

         11.6 Waiver; Consents. The failure by any party to exercise any right
under, or to object to the breach by any other party of any term, provision or
condition of, this Agreement shall not constitute a waiver thereof and shall not
preclude such party from thereafter exercising that or any other right, or from
thereafter objecting to that or any prior or subsequent breach of the same or
any other term, provision or condition of the Agreement. Any consent granted
pursuant to this Agreement shall be in writing, executed by the person
authorized by the consenting party to receive notices, and shall be a consent
only to the transaction, act or agreement specifically referred to in the
consent and not to other similar transactions, acts or agreements.

         11.7 Assignment. This Agreement shall not be assigned by any party
without the prior written consent of the other party, provided, however, that
Buyer may assign to any Buyer Purchaser the right to acquire any portion of the
Purchased Assets and Seller may assign this Agreement to any acquiror of all or
substantially all of its business or assets if such acquiror confirms and
acknowledges the obligations of Sellers under this Agreement and the Collateral
Documents except as otherwise provided therein. Any attempted assignment in
contravention with the foregoing shall be void. This Agreement shall be binding
on and inure to the benefit of the parties hereto, their successors and any
permitted assigns.

         11.8 Governing Law. This Agreement, including any dispute or
controversy arising out of or related to this Agreement or the breach thereof,
shall be subject to, governed by, and construed in accordance with, the
substantive and procedural laws of the State of New York, without reference to
its principles of conflict of laws.


         11.9 Parties in Interest. This Agreement is binding upon and shall

expressly provided in Article IX.

         11.10 Dispute Resolution. Any controversy or claim arising out of or
relating to this Agreement, or the breach, termination or validity hereof, shall

York administered by the American 
<PAGE>
 
                                     - 83 -


Arbitration Association (the "AAA") in accordance with the AAA Commercial
Arbitration Rules, including the Supplementary Procedures for Large, Complex
Disputes. The arbitrators shall be individuals selected by mutual agreement of
the parties hereto who are unaffiliated directly or indirectly with either party
and shall have had no such affiliation for a period of at least five years prior
to the date of this Agreement. In the event that the parties cannot reach
agreement on the selection of such arbitrators, the Seller and the Buyer shall
each name one individual, as describe above, who together will select a third
person, all of whom will then serve as the arbitrators. The arbitration shall be
governed by the United States Arbitration Act, 9 U.S.C. Sections 1-16 or
any successor provision, and judgment upon the award may be entered by any court
having jurisdiction. Any party to this Agreement may apply to any court having
jurisdiction hereof and seek injunctive or other preliminary relief to avoid
irreparable damage until the arbitration award is rendered or the claim or
controversy is otherwise resolved. Despite such action the parties will continue
to participate in good faith in the procedures specified in this Section 11.10.
Notwithstanding anything else in this Section 11.10 and without resort to any
arbitration, any party may initiate litigation in a state or federal court
having jurisdiction with respect to any controversy or claim arising out of this
Agreement and related to intellectual property rights. Except as otherwise
expressly authorized in this Agreement, the arbitrators shall be bound by
Article IX of this Agreement and may not make any ruling, finding or award that
does not comply with the terms and conditions of this Agreement. The arbitrators
shall order a prehearing conference and limited discovery consisting of
production of requested documents, a list of proposed witnesses, copies of all
exhibits to be used at arbitration, a summary of testimony of proposed expert
witnesses, and the examination by deposition of reasonably requested
representatives of each party. The arbitrators shall schedule and conduct the
hearing and may permit each party to make brief opening and closing statements.
Either party, at its own expense, may arrange to have the arbitration
proceedings recorded and/or transcribed.

         11.11 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but such counterparts
shall together constitute one and the same Agreement.

         "Accept Employment" means (i) accepting an offer of employment with any

    law of any jurisdiction only requires notification of a change in
    employment, or if Buyer and the Buyer Purchasers have only provided for such
    notification in any jurisdiction, "Accept Employment" shall mean the sending
    of such notification; provided, however, that Seller shall notify Buyer of
    any Person in such jurisdiction who has notified any of Sellers in writing
    prior to the Closing Date that such Person does not expect to continue
    employment with any of Buyer Purchasers after the Closing Date and such
    Persons providing written notice shall not be deemed to Accept Employment

           6.12.1 At Closing, Seller or the applicable Seller Subsidiary
     ("Sublandlord", and collectively, the "Sublandlords") and Buyer or the
     applicable Buyer Purchaser ("Subtenant", and collectively the "Subtenants")
     shall enter into the following subleases (the "Subleases"): (a) a sublease,
     in the form referred to on Annex 1.1 as the "Technology Park Sublease,"
     which form has been modified in certain respects by agreement of the
     parties to such sublease, pursuant to which Sublandlord will sublease to
     Subtenant certain space in the office building located at 600 Technology
     Park Drive, Billerica, Massachusetts; and (b) a sublease, in form
     reasonably acceptable to both Seller and Buyer pursuant to which
     Sublandlord will sublease to Subtenant certain space in the office building
     located at 7900 Westpark Avenue, McLean, Virginia. Sublandlord shall use
     reasonable efforts to obtain, prior to Closing, and shall deliver to
     Subtenant at Closing or at such later time that any such consent shall be
     obtained, if at all, all consents required to validly consummate the
     Subleases. Sublandlord shall be responsible for and shall promptly pay any
     and all costs associated with obtaining and delivering such consents, and
     Subtenant shall reasonably cooperate with Sublandlord in obtaining such
     consents, provided that Subtenant shall not be required to make any payment
     associated with obtaining such consent. The obtaining of such consents with
     respect to any particular Sublease shall not be a condition to Closing, but
     from and after the date of Closing, as provided in Article IX, Seller shall
     indemnify, defend and hold the Buyer Indemnified Parties harmless from and
     defend the Buyer Indemnified Parties, on an after-tax basis, from and
     against any and all Loss and Litigation Expense, which they or any of them
     may suffer or incur as a result of or arising from Seller's failure to seek
     or obtain the consent of the landlord, sublandlord or other party whose
     consent is required in connection with the making of the Sublease.

           6.12.2 At Closing, Seller or the applicable Seller Subsidiary
     ("Assignor," and collectively, the "Assignors") shall assign to Buyer or
     the applicable Buyer Purchaser ("Assignee," and collectively, the
     "Assignees") all of its right, title and interest in, to and under the Real
     Estate Leases listed on Annex 2.1.6, except for those Real Estate Leases so
     listed in which (as indicated on such Annex 2.1.6), the tenant is an
     Acquired Subsidiary (the "Acquired Subsidiary Leases") and except for the
     Real Estate Lease of premises located in Solna, Sweden, the disposition of
     which is addressed in Section 6.12.4 below, and the applicable Assignee
     shall assume all obligations of the applicable Assignor under each Real
     Estate Lease to be assigned hereunder arising after Closing, pursuant to
     certain Lease Assignment and Assumption Agreements substantially in the
     form attached to Annex 1.1 as the "Lease Assignments." Seller shall use
     reasonable efforts to obtain, prior to Closing, and shall deliver to Buyer
     at Closing or at such later time that any such consent shall be obtained,
     if at all, all consents required under the Real 
<PAGE>
 
     Estate Leases as a result of the assignment thereof, and all consents
     required under Acquired Subsidiary Leases as a result of the transfer of
     the ownership interests in such Acquired Subsidiaries contemplated under
     this Agreement. Seller shall be responsible for and shall promptly pay any
     and all costs associated with obtaining and delivering such consents, and
     Buyers shall reasonably cooperate with Sellers in obtaining such consents,
     provided that neither Buyer nor any Buyer Purchaser shall be required to
     make any payment associated with obtaining such consent nor grant any
     guarantee of any obligations as a condition to obtaining such consent. The
     obtaining of such consents with respect to any particular Real Estate Lease
     assignment or deemed transfer of an Acquired Subsidiary Lease (a "Lease
     Transfer") shall not be a condition to Closing, but from and after the date
     of Closing, as provided in Article IX, Seller shall indemnify, defend and
     hold the Buyer Indemnified Parties harmless from and defend the Buyer
     Indemnified Parties, on an after-tax basis, from and against any and all
     Loss and Litigation Expense, which they or any of them may suffer or incur
     as a result of or arising from Seller's failure to seek or obtain the
     consent of the landlord, sublandlord or other party whose consent is
     required in connection with the making of the Lease Transfer.

           6.12.3 At Closing, Seller and Buyer shall enter into a Master Space
     Sharing Agreement, substantially in the form attached to Annex 1.1 (the
     "Master Space Sharing Agreement"), which form has been modified in certain
     respects by agreement of the parties thereto, relating to the spaces listed
     on Annex 6.12.3 (the "Shared Spaces"), pursuant to which, among other
     things, Sellers shall grant to Buyer Purchasers the right to use and occupy
     certain areas in the Shared Spaces in exchange for the payment of certain
     amounts and Buyer Purchasers assuming certain obligations with respect to
     such areas. Any consents to the Master Space Sharing Agreement which may be
     required to be obtained under any of the Real Estate Leases shall not be a
     condition to Closing, and neither Sellers nor Buyers shall be required to
     seek to obtain such consents.

           6.12.4 With respect to the Real Estate Lease of premises located in
     Solna, Sweden (the "Sweden Lease"), Seller covenants and agrees that the
     rent payable by the applicable Buyer Purchaser for the premises under the
     Sweden Lease (the "Sweden Premises") shall not exceed the fair market
     rental value therefor (the "Fair Market Rental"). Seller and Buyer hereby
     agree for this purpose that the Fair Market Rental of the Sweden Premises
     is 237,500 Swedish Krona (SEK) per year (exclusive of property tax and
     VAT). Seller and Buyer further agree and acknowledge that the current rent
     payable under the Sweden Lease for the Sweden Premises is 269,700 SEK per
     year (exclusive of property tax and VAT). In order to satisfy its
     contractual obligation to assume responsibility for the amount by which the
     current rent payable under the Sweden Lease exceeds the Fair Market Rental,
     Seller shall use commercially reasonable efforts promptly following Closing
     to enter into an agreement with the landlord under the Sweden Lease
     pursuant to which, at no cost to Buyer or the applicable Buyer Purchaser,
     either: (a) the Sweden Lease shall be modified to provide that the rent
     payable thereunder from and after the date of Closing shall be equal to the
     Fair Market Rental, in which event Seller shall cause the applicable Seller
     Subsidiary to assign the Sweden Lease to the applicable Buyer Purchaser and
     the applicable Buyer Purchaser shall accept assignment
<PAGE>
 
     of the Sweden Lease, as so modified; or (b) the Sweden Lease shall be
     terminated and the applicable Buyer Purchaser shall enter into a new lease
     covering the Sweden Premises on terms satisfactory to the landlord and
     reasonably satisfactory to the applicable Buyer Purchaser, but calling for
     rental payments no greater than the Fair Market Rental. If the arrangements
     described in clauses (a) and (b) above have not been completed on or before
     March 31, 1997, then Seller shall cause the Sweden Lease to be assigned to
     the applicable Buyer Purchaser pursuant to an assignment agreement which
     will provide that Seller shall pay to the Buyer Purchaser on a monthly
     basis (retroactive to the Closing Date) an amount equal to the amount by
     which each monthly installment of rent payable under the Sweden Lease
     exceeds the monthly Fair Market Rental, and the applicable Buyer Purchaser
     shall accept such assignment. The provisions of the last three sentences of
     Section 6.12.2 shall apply in connection with any assignment of the Sweden
     Lease by the applicable Seller Subsidiary to the applicable Buyer
     Purchaser.

17.  Section 6.13 of the APA is hereby deleted in its entirety and replaced with
the following:

           Section 6.13 Reorganization in France. Buyer and Seller shall, and
     shall cause their respective Affiliates, to cooperate in the reorganization
     of the Business in France so that Wang Software Services Europe is
     converted from an SNC to an S.A. prior to the closing of the Transactions
     in France and that all of the assets and employees of the Business in
     France are transferred to such entity. At or before the closing in France,
     the Acquired Subsidiary in France shall enter into a sublease with Wang
     France S.A., the terms of which are set forth in Annex 6.13.

18.  Section 6.1.5 of the APA is hereby deleted in its entirety and replaced
with the following:

           6.1.5 Retention Payments. Sellers shall cause any U.S. Transferred
     Employees with unvested employer contributions under Sellers' or Acquired
     Subsidiaries' 401(k) Plans ("Unvested Contributions") to vest as of the
     Closing Date. Sellers shall provide Buyer with a statement of the Unvested
     Contributions for each affected Transferred Employee within five business
     days after the Closing Date. Seller shall reimburse Buyer for one-half of
     the payments made by Buyer or Buyer Purchasers to Employees pursuant to
     Buyer's retention plan for Transferred Employees, as amended from time to
     time; provided, that Seller shall be entitled to credit 50% of the Unvested
     Contributions against such reimbursement obligation; and provided further,
     that Seller's maximum reimbursement obligation hereunder shall be the
     difference between $5,000,000 and the Unvested Contributions.

19.  Article VI of the APA is hereby amended by inserting the following Section
6.26:

           Section 6.26 Buyer shall not (nor shall Buyer permit any of its
     Affiliates to), without the prior written consent of Seller, amend or

     Software Storage Management, Inc. 1991 Incentive Stock Plan outstanding on
     the Closing Date (collectively, the "Plan and Options") unless required to
     do so to comply with a change in Law. Seller shall not (nor 
<PAGE>
 
     shall Seller permit any of its Affiliates to), without the prior written
     consent of Buyer, amend or otherwise modify the terms of the Plan and
     Options unless required to do so to comply with a change in Law.

20.  Section 7.1.5 of the APA is hereby amended to substitute the term "Schedule

           9.3.1 Additional Indemnification by Buyer. From and after the Closing
     Date, Buyer shall indemnify and hold harmless the Seller Indemnified
     Parties, on an after-tax basis, from and against any and all Loss and
     Litigation Expense which they, or any of them, may suffer or incur as a
     result of or arising from any claim that the sale and assignment by the
     Acquired Subsidiaries of certain of their assets to the Buyer or any Buyer
     Purchaser as provided in Section 5.10 resulted in the violation of any bulk
     sales, fraudulent conveyance, fraudulent transfer, insolvency, illegal
     dividend, or related law or regulation in any jurisdiction or the violation
     or breach of any fiduciary duty of any shareholder, director or officer of
     any Acquired Subsidiary. Notwithstanding anything to the contrary contained
     in Section 9.4, none of the limitations contained in Section 9.4 shall

                       WANG STRUCTURES FOR GLOBAL GROWTH

                        CREATES OFFICE OF THE PRESIDENT
            APPROVES MODIFICATION OF CEO TUCCI'S EMPLOYMENT CONTRACT


BILLERICA, Mass. -- (March 28, 1997) -- Wang (NASDAQ: WANG) today announced that
it has created an Office of the President, reporting to Chairman and CEO Joseph
M. Tucci, consistent with the company's focus as a leading provider of network
and desktop integration and services, worldwide. Serving in the Office of the
President will be: Jose Ofman, president and chief operating officer -Americas,
and Mias van Vuuren, chief operating officer - International.

     Mr. Ofman joins Wang from Electronic Data Systems (EDS) where he most
recently held the position of corporate vice president and group executive. Mr.
Ofman, whose career with EDS spanned over 25 years, held several senior
positions there. He was the architect of EDS's entry into the travel and
transportation business, a global business that grew well in excess of $600
million in annual revenues. Previously, he had managed EDS's billion dollar per
year relationship with General Motors' largest car group which included
Chevrolet, Pontiac, GM of Canada and GM of Mexico. He was also president of
EDS's Government Services Division, and of EDS, Mexico.

     For 26 years, Mr. van Vuuren has successfully managed international
operations within the information technology (IT) industry. Prior to joining
Wang in 1993, he served 14 years with IBM and 11 years with Unisys where he held
the position of vice president and group manager, Europe. He joined Wang in
1993, as senior vice president and general manager for Europe, Africa and the
Middle East and became president of international operations in 1994. Under his
leadership, Wang's international business has contributed significantly to
Wang's overall success.

     "Our new management structure aligns our core businesses worldwide,
reinforcing Wang's ability to take advantage of the growing markets at home and
abroad," said Tucci.  "Jose's dynamism and experience in building successful
businesses will add to our momentum as we focus on the highly profitable growth
segments of the IT services market.  Mias' continued guidance of our operations
outside of the Americas will ensure that we remain competitive and successful in
international markets, providing our customers consistent global delivery."

     In a related announcement, the company said its board has approved a
modification of Joseph M. Tucci's employment agreement, in recognition of the
leadership role he has played and to more closely link his compensation to
shareholder value, and  more closely align his compensation to that of other
CEOs in similar business situations. The last comprehensive restatement of Mr. 
Tucci's employment agreement occurred on March 9, 1993.

     Key provisions of the new contract, which will be outlined in the company's
8K include:  an increase in base salary from $605,000 to $750,000, to equalize
his pay with other CEOs in similar situations; a retention bonus of $4 million,
contingent upon Mr. Tucci's continued employment; and an increase in long-term
incentives in the form of a restricted stock award and stock option grants
designed to make a substantial portion of Mr. Tucci's future compensation
conditioned upon the creation of shareholder value.

     "Joe Tucci has successfully guided Wang through several critical stages of
development, including greatly improving its financial performance, which has
helped to raise Wang's market capitalization from approximately $400 million in
1994 to nearly $1 billion.  He has been the architect of Wang's strategy to
focus the company on the large opportunity in the global desktop and network
integration and services business, conceiving and negotiating a series of
strategic acquisitions, including I-NET. The recent sale of Wang Software to
Eastman Kodak for $260 million marks the completion of his repositioning
strategy," said Michael W. Brown of Wang's board of directors.  "The board is
confident that under Joe's continued leadership Wang will focus its energies on
high growth segments of IT services and reach new levels of success for its
customers and shareholders."
