<Page>

regulations, and to take no position inconsistent with the allocation set

proceeding. Each of Buyer and Seller shall timely file the appropriate forms
in accordance with the requirements of Section 1060 of the Code and this
Section.

         1.7.     PURCHASE OF SHARES BY BUYER. In the event Buyer Parent
issues debt or equity securities to non-Affiliates (as defined in the
Securities Act of 1933, as amended) prior to the second anniversary of the
Closing Date, the proceeds of which (gross of underwriting commissions,
discount and expenses) exceed $5,000,000, other than in a firm commitment
registered public offering, (a "FINANCING EVENT"), Buyer Parent shall, within
ten (10) days of such consummation, provide written notice (the "Notice") to
Seller of the occurrence of the Financing Event. Within ten (10) days from
Seller's receipt of the Notice, Seller may require Buyer Parent to purchase
from Seller shares of Common Stock received as part of the Purchase Price, at
a price equal to (i) in the case of a Financing Event involving the sale of
Common Stock of the Buyer Parent, the purchase price of the Common Stock sold
therein, or (ii) in the case of any other Financing Event, the price equal to
the average of the closing sale prices of the Common Stock on the Nasdaq
National Market during the five (5) trading days immediately preceding the
date of the Financing Event; PROVIDED, HOWEVER, that in no event shall Buyer
Parent be obligated to use greater than twenty percent (20%) of Buyer
Parent's aggregate proceeds from the Financing Event for such repurchase. In
the event of a Financing Event within two years of the Closing Date, Buyer
Parent shall have the right to purchase from Seller up to one hundred percent
(100%) of the Common Stock received as part of the Purchase Price provided
that the consideration Seller receives for such Common Stock (net of any
underwriting commissions, discounts and expenses) as calculated above is an
amount equal to or greater than $7.00 per share (as appropriately adjusted
for stock splits, stock combinations, stock dividends and recapitalizations).

                  2.   REPRESENTATIONS AND WARRANTIES OF SELLER

         Seller hereby represents and warrants to Buyer and Buyer Parent,
subject to such exceptions as are disclosed in the disclosure schedule
supplied by Seller to Buyer Parent (the "Seller Disclosure Schedule") dated
as of the date hereof, as follows (notwithstanding anything to the contrary
contained herein, Seller is not making any representation or warranty with
respect to the Excluded Assets or Excluded Liabilities):

         2.1.     ORGANIZATION AND STANDING. Seller (a) is a corporation duly
incorporated, validly existing and in good standing under the laws of the
State of Delaware, (b) has full right, power and authority to enter into and
perform and do all things contemplated under this Agreement necessary to give
effect to the provisions of this Agreement, to own and lease the Assets and
to carry on and operate the CSC Operations as now being conducted and
proposed to be conducted by it under existing agreements, (c) is duly
qualified or licensed to do business and is in good standing as a foreign
corporation in every jurisdiction in which the character of the Assets or
nature of the CSC Operations requires such qualification, except to the
extent that the failure to be so qualified or licensed would not have a
material adverse effect on the CSC Operations or Assets, and (d) except as
set forth on Paragraph 2.1 of the Disclosure Schedule, does not own any of
the Assets, and does not conduct any of the CSC Operations, through any other
corporation, limited liability company, partnership or other entity.

                                       4
<Page>

         2.2.     AUTHORIZATION AND BINDING OBLIGATIONS. The execution,
delivery and performance by Seller of this Agreement have been duly and
validly authorized by all necessary corporate action. This Agreement has been
duly executed and delivered by Seller and constitutes the valid and binding
agreement of Seller, enforceable in accordance with its terms, except as its
enforceability may be limited by bankruptcy, insolvency, moratorium or other
laws relating to or affecting creditors' rights generally and the exercise of
judicial discretion in accordance with general equitable principles.

         2.3.     NO CONTRAVENTION. The execution, delivery and performance
of this Agreement, the consummation of the transactions contemplated hereby
and the compliance with the provisions hereof by Seller does not (a) violate
any provision of the certificate of incorporation or bylaws of Seller, (b)
conflict with, result in the breach of, or constitute a default under, or
result in the creation of any Lien upon any of the Assets, or require any
authorization, consent, approval, exemption or other action by or notice to
any third party, court or other governmental or administrative body, under
the provisions of any agreement (including, without limitation, the Merger
Agreement (as defined below)) or other instrument to which Seller is a party
or by which any of the Assets are bound or affected or (c) violate any laws,
regulations, orders or judgments applicable to Seller, except in each of
clause (b) and (c), where the conflict, breach, default, Lien, violation or
failure to give or receive such authorization, consent, approval, exemption
or other action would not have a material adverse effect on the CSC
Operations or Assets or on Seller's ability to consummate the transactions
contemplated by this Agreement (a "MATERIAL ADVERSE EFFECT").

         2.4.     COMPLIANCE WITH LAWS. Seller has complied with, and is now
in compliance with, all material laws, rules, regulations, orders, judgments
and decrees of any governmental, regulatory or administrative body, agency or
authority, or any court or judicial authority (each, an "AUTHORITY")
applicable to the CSC Operations. Seller possesses each material franchise,
license, permit, authorization, certification, consent, variance, permission,
order or approval of or from any Authority, and has filed all filings,
notices or recordings with any such Authority (collectively, "LICENSES")
material to, or necessary for the conduct of, the CSC Operations and is in
compliance with each of such Licenses, except to the extent that the failure
to comply would not have a Material Adverse Effect. Each such License is
identified on PARAGRAPH 2.4 of the Disclosure Schedule. No proceeding or
other action is pending or, to the best knowledge of Seller, threatened, to
revoke, amend, or limit any License.

         2.5.     TAX MATTERS. Seller has, within the times and in the manner
prescribed by law, filed all required tax returns, including sales and use
tax returns, has paid or provided for all taxes, including sales and use
taxes owed by Seller, with respect to the CSC Operations (whether or not
shown on any tax return to be due and owing by it), has paid or provided for
all deficiencies or other assessments of taxes, interest or penalties owed by
it, and all such tax returns were correct and complete in all material
respects when filed. No taxing Authority has asserted any claim for the
assessment of any additional taxes of any nature with respect to any periods
covered by any such tax returns, and all taxes or other charges required to
be withheld or collected by Seller with respect to the CSC Operations have
been duly withheld or collected and, to the extent required, have been paid
to the proper taxing Authority or properly segregated or deposited as
required by law.

                  (a)      As used in this Agreement, the term "ERISA
AFFILIATE" means any person or entity (whether or not incorporated) which, by
reason of its relationship with Seller or a subsidiary is required to be
aggregated with Seller or a subsidiary under Sections 414(b), 414(c), 414(m)
or 414(o) of the Code, or which, together with Seller or a subsidiary is a

change in control, retention, stock option or other equity based or other

any claims against Seller relating to employment or similar matters
(including, without limitation, compensation and benefits) with Seller with
respect to the CSC Operations. There are not in existence or, to the

governmental investigation, suit, action, arbitration, legal, administrative
or other proceeding of any nature, domestic or foreign, criminal or civil, at

state securities laws.

                  (a)      Seller understands that (i) when issued, the
Shares will not be registered under the Securities Act or any state
securities laws by reason of their issuance in a transaction exempt from the
registration requirements of the Securities Act and applicable state

                  (c)      Seller has relied upon independent investigations
that it and its representatives have made and is fully familiar with the
business, results of operations, financial condition, prospects and other
affairs of Buyer Parent and realizes that the Shares are a speculative
investment involving a high degree of risk for which there is no assurance of
any return.

                  (d)      Seller has such knowledge and experience in
financial and business affairs, including investing in companies similar to
Buyer Parent, and is capable of determining the information necessary to make
an informed investment decision, of requesting such information from Buyer
Parent, and of utilizing the information that it has received from Buyer or
Buyer Parent to evaluate the merits and risks of its investment in the Shares
and is able to bear the economic risk of its investment in the Shares, and
understands that it must do so for an indefinite period of time.

                  (e)      Seller and its attorneys, accountants, investment

         3.3.     NO CONTRAVENTION. The execution, delivery and performance
of each of the Transaction Agreements, the consummation of the transactions
contemplated hereby and thereby and the compliance with the provisions hereof
and thereof by Buyer and by Buyer Parent do not (a) violate any provision of
the articles of incorporation or bylaws of Buyer or Buyer Parent, (b)
conflict with, result in the breach of, or constitute a default under, or
require any authorization, consent, approval, exemption or other action by or
notice to any third party, court or other governmental or administrative
body, under the provisions of any agreement or other instrument to which
Buyer or Buyer Parent, as the case may be, is a party or by which the
property of Buyer or Buyer Parent is bound or affected, or (c) violate any
laws, regulations, orders or judgments applicable to Buyer.

         3.4.     ISSUANCE OF THE SHARES. Upon issuance, the Shares shall be
validly issued, fully paid and non-assessable and shall be free and clear of

including material filed pursuant to Section 13(a) or 15(d) thereof. Buyer
Parent has delivered or made available to Seller true and complete copies of

such SEC Documents, and none of the SEC Documents contained any untrue
statement of a material fact or omitted to state a material fact required to
be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading. The
SEC Documents contain all material information concerning Buyer Parent, and
no event or circumstance has

                                       13
<Page>

occurred which would require Buyer to disclose such event or circumstance in
order to make the statements in the SEC Documents not misleading on the date
hereof but which has not been so disclosed.

with respect to any claim by any broker, agent, or finder claiming to have
acted on behalf of Buyer or Buyer Parent respecting the subject matter hereof.

         3.7.     INFORMATION FURNISHED TO SELLER. To the knowledge of Buyer
and Buyer Parent, no information furnished by or on behalf of Buyer or Buyer
Parent to Seller contains any untrue statement of a material fact or omits to

Buyer and Buyer Parent, all written information, in whatever form, furnished
by Buyer or Buyer Parent to Seller was true and correct as of the date so
furnished and, except as the accuracy thereof is affected by the passage of
time, remains true and correct in all material respects as of the date hereof.

                  (b)      Any action, suit or proceeding challenging the
sale or assignment of the Assets or the transactions contemplated by this

                  (d)      Any other development which would prevent or raise
a material doubt about the possibility of the satisfaction of any condition
to Closing of such notifying party set forth in Section 5; PROVIDED HOWEVER,
that the delivery of any notice pursuant to this Section 4.8 shall not (1)
limit or otherwise affect any remedies available to the party receiving such

Agreement.

         4.9.     UPDATING OF DISCLOSURE SCHEDULE. The Seller may (but will
not be required to), from time to time prior to or on the Closing Date, by
notice in accordance with this Agreement, supplement or amend the Disclosure
Schedule, including without limitation one or more supplements or amendments
to correct any matter which would otherwise give rise to a breach of any
representation, warranty or covenant herein contained, solely to the extent
such matter arose after the execution of this Agreement. If a supplement or
amendment of the Disclosure Schedule is issued, which supplement or amendment
results in a material change to the representations and warranties of the

being its sole remedy relating to matters set forth in amendments or
supplements to the Disclosure Schedule. Notwithstanding any other provision
hereof but subject to the immediately preceding sentence, each supplement or
amendment of the Disclosure Schedule (to that extent permitted by the second

and in respect of:

expressly assumed by Buyer or Buyer Parent, as the case may be (for the
purposes of this Section 6, collectively, the "PURCHASER"), as provided in
Section 1.4 of this Agreement or in Section 7.6 hereof, all liabilities and
obligations of Seller of any kind or nature whatsoever relating to the
Assets, whether accrued, absolute, fixed, contingent or otherwise, known or
unknown;

                  (b)      MISREPRESENTATIONS. Any damage, loss, cost,
expense or liability (including reasonable attorneys' fees) resulting to
Purchaser from any false or inaccurate representation, breach of warranty or
non-fulfillment of any agreement on the part of Seller under this Agreement
or from any misrepresentation in any closing certificate or other instrument
required to be furnished by Seller to Purchaser hereunder; and

                                       19
<Page>

                  (c)      ACTIONS AND SUITS. All claims, actions, suits,
proceedings, demands, assessments, judgments, costs and expenses, including,
without limitation, legal fees and expenses, incident to any of the foregoing.

         6.2.     INDEMNIFICATION BY BUYER AND BUYER PARENT. The Buyer and
Buyer Parent shall joint and severally indemnify and hold harmless Seller, at
all times after the Closing Date, against and in respect of:

                  (a)      ASSUMED LIABILITIES. Any loss arising from the
Assumed Liabilities;

                  (b)      MISREPRESENTATIONS. Any damage, loss, cost,
expense or liability (including reasonable attorneys' fees) (collectively,
"LOSS") resulting to Seller from any false or inaccurate representation,
breach of warranty or non-fulfillment of any agreement on the part of Buyer
under this Agreement or from any misrepresentation in or any omission from
any certificate or other instrument required to be furnished by the Purchaser
to Seller hereunder;

                  (c)      ACTION OR INACTION OF BUYER OR BUYER PARENT. Any
Loss arising from any action or inaction by Buyer or Buyer Parent after the
Closing Date and arising from or in connection with the operation of the CSC
Operations or the Assets after the Closing Date; and

                  (d)      ACTIONS AND SUITS. All claims, actions, suits,
proceedings, demands, assessments, judgments, costs and expenses, including,
without limitation, legal fees and expenses, incident to any of the foregoing.

         6.3.     INDEMNIFICATION PROCEDURE.

                  (a)      A party that may be entitled to indemnification
pursuant to Section 6.1 or Section 6.2 (the "INDEMNITEE") shall promptly give
written notice (a "NOTICE OF CLAIM") to the party liable for such
indemnification (the "INDEMNITOR"). A Notice of Claim shall set forth (a) a
description, in reasonable detail, of the facts and circumstances with
respect to the subject matter of such claim or potential claim for
indemnification, and (b) the anticipated total amount of the indemnification
claim (including any costs or expenses which have been or may be reasonably
incurred in connection therewith). Upon receipt of a Notice of Claim, the
Indemnitor may elect to cure the circumstances giving rise to the
indemnification claim (the "EVENT OF LOSS") within thirty (30) days after the
date of receipt of the Notice of Claim. If such cure cannot be effected
within such 30-day period, payment of the amount of actual damage, loss,
cost, expense or liability (including reasonable attorneys' fees)
(collectively, "DAMAGES") due to the Indemnitee as set forth in the Notice of
Claim shall be made by Indemnitor no later than the thirtieth (30th) day
after the date of the Notice of Claim (or such later date as the Indemnitor
receives written notice that the Indemnitee has suffered Damages). The
Indemnitee's failure to give prompt notice or to provide copies of documents
or to furnish relevant data shall not constitute a defense (in whole or in
part) to any claim by the Indemnitee against the Indemnitor for
indemnification, except and only to the extent that such failure shall have
caused or increased such liability or adversely affected the ability of the
Indemnitor to defend against or reduce its liability.

                  (b)      If any Notice of Claim relates to any claim made
against an Indemnitee by a third person, the Notice of Claim shall state the
nature, basis and amount of such claim. The Indemnitor shall have the right,
at its election, by written notice to the Indemnitee, to assume the

                                       20
<Page>

defense of the claim as to which such notice has been given. Except as
provided in the next sentence, if the Indemnitor so elects to assume such
defense, it shall diligently and in good faith defend such claim and shall
keep the Indemnitee reasonably informed of the status of such defense, and
the Indemnitee shall cooperate fully with the Indemnitor in the defense of
such claim, PROVIDED that in the case of any settlement providing for
remedies other than monetary damages for which indemnification is provided,
the Indemnitee shall have the right to approve the settlement, which approval
shall not be unreasonably withheld or delayed. If the Indemnitor does not so
elect to defend any claim as aforesaid or shall fail to defend any claim
diligently and in good faith (after having so elected), the Indemnitee may
assume the defense of such claim by written notice to the Indemnitor and take
such other action as it may elect to defend or settle such claim as it may
determine in its reasonable discretion, PROVIDED that the Indemnitor shall
have the right to approve any settlement, which approval will not be
unreasonably withheld or delayed.

                  (c)      None of the parties hereto shall have any
obligation to indemnify the other parties hereto or otherwise have liability
to the other parties hereto for consequential, collateral, special,
incidental, punitive or indirect damages, lost profits or similar items.

                  (d)      Seller shall have no liability under this Section
6 to the extent arising from actions taken or not taken by Buyer or Buyer
Parent or their affiliates after the Closing Date.

         6.4.     LIMITATIONS ON INDEMNIFICATION.

                  (a)      BASKET AMOUNT. The indemnification provided for in
Section 6.1 shall not apply to (i) Damages relating to an individual
indemnification claim if such amounts do not exceed $10,000 in the aggregate,
whereupon claim may be made for the entire amount of Damages, provided that
the limits of clause (ii) have been met, and (ii) until Purchasers'
collective claims for indemnification exceed $50,000 in the aggregate,
whereupon claim may be made for all amounts in excess of $50,000, subject to
the limits of clause (i) herein (it being understood that Damages relating to
claims below $10,000 may be included for purposes of determining whether the
limits of this clause (ii) has been satisfied).

                  (b)      INSURANCE PROCEEDS AND OTHER SET-OFFS. The amount
of any Damages for which indemnification is provided under Section 6.1 or
Section 6.2 shall be net of any amounts recovered or recoverable by the
Indemnitee under insurance policies with respect to such Damages. Upon making
any payment to an Indemnitee for any indemnification claim, the Indemnitor
shall be subrogated, to the extent of such payment, to any rights which the
Indemnitee may have against the third party with respect to the subject
matter underlying such indemnification claim.

         6.5.     PAYMENT OF INDEMNIFICATION CLAIMS. In the event that Seller
is entitled to indemnification pursuant to Section 6.2, Buyer Parent shall
make payment of such indemnification claim in cash. In the event that
Purchaser is entitled to indemnification pursuant to Section 6.1, Seller
shall effect the payment of such indemnification to an Indemnitee by, and in
accordance with, the terms of the Escrow Agreement, (i) first, directing the
Escrow Agent to return to Buyer Parent the Escrowed Note, in which case Buyer
Parent shall tender to the Escrow Agent in substitution therefor a Note
reduced in principal amount by the amount of Seller's indemnification
obligation to the Indemnitee (which Note shall thereupon become the "ESCROWED

                                       21
<Page>

NOTE"), or (ii) second, if the Escrow Note is insufficient to satisfy the
Seller's indemnification obligation, by directing the Escrow Agent to return
to Buyer Parent an integral number of Escrowed Shares equal in value to
Seller's indemnification obligation to Buyer (in which case the value of each
such Escrowed Share shall be equal to the average of the closing sale prices
of the Common Stock on the Nasdaq National Market during the ten (10) trading
days immediately preceding the date on which the Escrow Agent returns such
Escrowed Shares to Buyer), and (iii) third, if the Escrowed Note and the
Escrowed Shares are insufficient to satisfy the Seller's indemnification
obligation, by directing the Escrow Agent to pay the Buyer Escrowed Cash in
amounts equal to Seller's indemnification obligation to Buyer under Section
6.1. Resort to the Escrowed Shares, the Escrowed Note and the Escrowed Cash
shall constitute the sole remedy of Buyer and Buyer Parent under this
Agreement, except with respect to fraud or willful misconduct perpetrated by
Seller.

         6.6.     EXCLUSIVE REMEDY. After the Closing Date, this Section 6
shall provide the sole and exclusive remedy for any and all Damages related
to this Agreement sustained or incurred by Buyer, Buyer Parent or Seller or
their respective successors and assigns and affiliates.

                        7.   POST-CLOSING COVENANTS

         7.1.     FURTHER ASSURANCES; COOPERATION. The parties shall, at any
time, and from time to time, after the Closing Date, execute and deliver such
further instruments of conveyance and transfer and take such additional
action as may be reasonably necessary to effect, consummate, confirm or
evidence the transactions contemplated by this Agreement, including
reasonable cooperation with respect to the preparation of tax returns for
periods prior to the Closing Date.

         7.2.     DELIVERY OF ASSETS. Seller agrees that it will transfer or
make available to Buyer, promptly after the receipt thereof, any property
that Seller receives after the Closing Date in respect of the Assets
transferred or intended to be transferred to Buyer under this Agreement.

         7.3.     BOOKS AND RECORDS. Buyer shall preserve and retain the
corporate, accounting, tax, legal and other records of the CSC Operations
that shall come into Buyer's possession as a result of the transactions
contemplated hereby for a period of not less than five (5) years from the
Closing Date and give reasonable access to Seller, and Seller's officers,
auditors, counsel, and other representatives for the purpose of preparing or
defending tax returns or for other reasonable business purposes.

         7.4.     LITIGATION SUPPORT. In the event and for so long as any of
the Seller, the Buyer, the Buyer Parent or any of their affiliates actively
is contesting or defending against any third party action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection
with (i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or
prior to the Closing Date involving the Seller or any of the Assets, Seller
shall furnish Buyer Parent and its authorized representatives reasonable
access to Seller's books, records and other information, concerning the
Assets and the CSC Operations, including, without limitation, access to
Seller's officers, auditors, counsel and other representatives primarily
involved in the CSC Operations; PROVIDED, HOWEVER, that in each

                                       22
<Page>

instance mutually satisfactory arrangements shall be made in advance in order
to avoid interruption and minimize interference with the normal business and
operations of Seller.

         7.5.     DESTRUCTION OF COPIES OF CERTAIN ASSETS. After the Closing
Date, Seller shall, upon the written request of Buyer, immediately destroy or
erase all of Seller's copies of computer software and CSC Operations records
included in the Assets and, upon Buyer's request, promptly confirm
destruction of same by signing and returning to Buyer an "affidavit of
destruction" acceptable to Buyer; PROVIDED, HOWEVER, that Seller shall be
entitled to retain a copy of those specific records, and only those specific
records, that contain information that (i) is not related to the CSC
Operations, (ii) is neither confidential nor privileged or (iii) Seller has a
reasonable need to retain. Following the Closing Date, Buyer and Buyer Parent
shall grant to Seller and its representatives, at Seller's reasonable
request, reasonable access to and the right to make copies of those records
and documents covering any period prior to the Closing Date related to the
CSC Business or the Assets as may be reasonably necessary for litigation,
preparation of financial statements, tax returns and audits or other valid
business purposes. If Buyer or Buyer Parent elects to dispose of such
records, Buyer shall first give Seller sixty (60) days' written notice,
during which period Seller shall have the right to take such records without
further consideration.

         7.6.     EMPLOYEE MATTERS.

                  (a)      Buyer and Buyer Parent do not and will not assume
the sponsorship of, the responsibility for contributions to, or any liability
under or in connection with, any Employee Benefit Plan. Without limiting the
foregoing, Seller shall be liable for continuation coverage (including any
penalties, excise taxes or interest resulting from the failure to provide
continuation coverage) required by Section 4980B of the Code with respect to
(i) qualifying events incurred by any CSC Operations Employee who does not
become an employee of Buyer on or immediately following the Closing (or
covered dependents or qualified beneficiaries of such employee), and (ii) any
qualifying events which occur on or before the Closing Date incurred by any
CSC Operations Employee who becomes an employee of Buyer on or following the
Closing Date (or covered dependents or qualified beneficiaries of such
employee). Buyer will in no event be deemed to be a successor employer
(within the meaning of Treasury Regulation Section 54.4980B-2) of Seller for
purposes of applying the provisions of Section 4980B of the Code following
the Closing with respect to any current or former employee of Seller.

                  (b)      Buyer shall, as of the Closing Date, offer
employment to those CSC Operations Employees listed on the Offeree Schedule,
which offer shall indicate that Buyer shall provide to each such CSC
Operations Employee initial compensation at a rate equivalent to the rate of
compensation provided to such CSC Operations Employee by Seller at the time
of offer. Any such CSC Operations Employee who accepts Buyer's offer of
employment and who, within seven days of the Closing Date, commences
employment with Buyer by reporting for work and being actively employed by
Buyer for at least one day is hereinafter referred to as a "TRANSFERRED
EMPLOYEE." For a period of at least one year following the Closing Date,
Buyer shall provide or cause to be provided to Transferred Employees
compensation and benefits that are substantially comparable, in the
aggregate, to the compensation and benefits (exclusive of any such
compensation and benefits consisting of or based on any equity securities but
including all

                                       23
<Page>

severance policies of the Seller) provided to them by Seller under the
Employee Benefit Plans immediately prior to the Closing. Subject to the
satisfaction of applicable enrollment requirements, each Transferred Employee
(and its or her eligible spouse or dependents) who, as of the Closing Date,
participates in Employee Benefit Plans of Seller shall immediately following
such Transferred Employee's commencement of employment with Buyer, become
eligible to participate in employee benefit plans maintained by Buyer for its
employees.

                  (c)      For purposes of determining eligibility to
participate or levels of benefits or entitlement to benefits under the
Buyer's benefit plans, programs and arrangements (including, for the
avoidance of doubt but without limitation, any vacation or vacation pay plan,
program or arrangement) each Transferred Employee shall be credited with his
or her years of service with the Seller or any affiliate. The Buyer shall
cause any preexisting condition, actively-at-work, or similar requirement
under any of their benefit plans, programs or arrangements to be waived in
the case of any Transferred Employee. For purposes of determining any
deductibles or other obligations (such as co-insurance payments) similarly
subject to a dollars or percentage cap under any benefit plan, program or
arrangement of the Buyer for the year in which the Closing occurs, each
Transferred Employee shall be credited with amounts paid or deducted under
the comparable employee program of Seller during the year in which the
Closing occurs.

                  (d)      The Buyer shall use reasonable best efforts to
obtain necessary governmental approvals and authorizations, including the
obtaining of Visa and other work permits, so as to permit the continued
employment of foreign persons.

                  (e)      Buyer Parent shall pay to Seller $136,725 in cash
(the "SEVERANCE COSTS PAYMENT") on the Closing Date for payment obligations
of Seller resulting from claims arising out of or in connection with
severance costs for CSC Operations Employees discharged by Seller on or prior
to the Closing Date whether or not such payment obligations are payable by
Seller on or prior to the Closing Date.

         7.7.     NON-COMPETITION.

                  (a)      During and for a period of two years following the
Closing, Seller shall not (other than on behalf of Buyer or Buyer Parent),
without the prior written consent of Buyer or Buyer Parent, engage in a
Competitive Business Activity (as defined below) anywhere in the Restricted
Territory (as defined below). The term "COMPETITIVE BUSINESS ACTIVITY" shall
mean (i) the business of the CSC Operations as conducted by Seller as of the
date hereof or as of the Closing Date; (ii) acquiring or having an ownership
interest in any entity that derives a majority of its gross revenues from any
business that competes with the CSC Operations as conducted as of the date
hereof or as of the Closing Date (except for ownership of five percent (5%)
or less of any entity); or (iii) participating in the operation, management
or control of any firm, partnership, corporation, business or other entity
described in clause (ii) of this sentence. The parties acknowledge and agree
that the provisions of this Section 7.7 shall in no event preclude Polycom
(as successor to Seller) from engaging in any business activity conducted by
it as of the date hereof, including without limitation problem management,
selling and developing multipoint bridges, or scheduling, collaboration and
management software. The term "RESTRICTED TERRITORY" shall mean all foreign
countries where Seller conducted CSC Operations on or after

                                       24
<Page>

January 1, 2001, the United States of America and each and every state,
county, city, municipality or other political subdivision thereof.

                  (b)      The covenants contained in Section 7.7(a) shall be
construed as a series of separate covenants, one for each country, state,
county, city, municipality or other political subdivision of the Restricted
Territory. Except for geographic coverage, each such separate covenant shall
be deemed identical in terms to the covenant contained in Section 7.7(a).

                  (c)      Seller acknowledges that the covenants contained
in this Section 7.7 are reasonable and valid in geographical and temporal
scope and content and in all other respects, and are necessary for the
adequate protection of the legitimate business interests of Buyer and of
Buyer Parent, because, among other things, Buyer or Buyer Parent conducts
business throughout the world, the United States, Buyer or Buyer Parent is
engaged in a highly competitive industry, and Seller has had unique access to
confidential business information and trade secrets included in the Assets.
Seller also acknowledges that any breach of the covenants set forth in this
Section 7.7 will give rise to irreparable injury to Buyer or Buyer Parent,
that the remedy at law of Buyer or Buyer Parent for any such breach or
threatened breach will be inadequate and that, in addition to any other
remedy therefor that Buyer or Buyer Parent may have, it shall be entitled to
temporary injunctive relief before trial from any court of competent
jurisdiction as a matter of course and to permanent injunctive relief without
the necessity of proving actual damages and without the requirement of any
bond or other security.

                  (d)      Seller agrees that the existence of any claim or
cause of action by Seller against Buyer or Buyer Parent shall not constitute
a defense to the enforcement by Buyer of the covenants set forth in this
Section 7.7, and that any such claim or cause of action against Buyer shall
be litigated separately.

                  (e)      If, in any judicial proceeding, a court refuses to
enforce any of the separate covenants (or any part thereof) set forth in this
Section 7.7, then such unenforceable covenant (or such part) shall be
eliminated from this Agreement to the extent necessary to permit the
remaining separate covenants (or parts thereof) to be enforced, and such
remaining covenants shall be given full effect without regard to the invalid
covenant (or part thereof). In the event that any of the separate covenants
(or any part thereof) set forth in this Section 7.7 is deemed by a court to
exceed the geographical or temporal scope or content or other limitations
permitted by applicable laws, then such covenant (or part thereof) shall be
reformed to the geographical or temporal scope or content or other
limitations, as the case may be, permitted by applicable laws, and, in such
reduced form, shall be given full effect.

         7.8.     NON-SOLICITATION. For a period of one (1) year from the
Closing Date, Seller shall not, without the prior written consent of Buyer or
Buyer Parent (i) solicit the employment of any of the Transferred Employees
or (ii) hire any Transferred Employee whose employment Buyer Parent or any
subsidiary of Buyer Parent has terminated within 60 days of such solicitation
or hire; PROVIDED, HOWEVER, that this Section 7.7(e) shall not prevent
advertisements, solicitations, position listings or notices of employment
opportunities that are published or made available to the public or hiring of
personnel responding thereto.

                                       25
<Page>

         7.9.     CONSENTS. For a period of six (6) months following the
Closing, Seller shall use its reasonable commercial efforts to obtain all
written consents which are required under the Assumed Contracts; provided
that Seller shall not be required to make any payments to obtain such
consents. Buyer and Buyer Parent shall cooperate with Seller to the extent
reasonably necessary to obtain any such written consent.

         7.10.    LICENSING AGREEMENT WITH FVC. For a period of 45 days
following the Closing, Seller shall use its reasonable commercial efforts to
assist Buyer and Buyer Parent in the obtaining a software licensing agreement
from First Virtual Communications, Inc. ("FVC") providing Buyer or Buyer
Parent with a transferable 200-port license to the FVC Application Server
Product.

         7.11.    PURCHASE AND SALE OF SHARES. For a period of one year
following the Closing Date, Seller shall not, without the prior written
consent of Buyer Parent, (i) purchase any shares of capital stock of Buyer
Parent (other than capital stock of Buyer Parent acquired pursuant to this
Agreement), or (ii) sell in any three month period shares of capital stock of
Buyer Parent in excess of the maximum amount permitted under Rule 144(e)(1)
promulgated under the Securities Act.

                                8.   MISCELLANEOUS

         8.1.     GOVERNING LAW. This Agreement shall be governed in all
respects by the laws of the State of Delaware, without giving effect to any
choice or conflict of law provision or rule (whether of the State of Delaware
or any other jurisdiction that would cause the application of the laws of any
jurisdiction other that the State of Delaware).

         8.2.     JURISDICTION. Any suit, action or proceeding seeking to
enforce any provision of, or based on any matter arising out of or in
connection with, this Agreement or the transactions contemplated hereby shall
be brought exclusively in Delaware or an United States Federal court sitting
in Delaware, and each of the parties hereby expressly submits to such
jurisdiction and venue of such court (and of the appropriate appellate courts
therefrom) in any such suit, action or proceeding and irrevocably waives, to
the fullest extent permitted by law, any objection that it may now or
hereafter have to the laying of the venue of any such suit, action or
proceeding in any such court or that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.

         8.3.     SURVIVAL; TERMINATION.

                  (a)      SURVIVAL. Except as otherwise expressly provided
herein, the several representations, warranties, covenants, and agreements of
the parties contained in this Agreement shall be deemed to be material and to
have been relied upon by Buyer, Buyer Parent and Seller notwithstanding any
investigation made by Buyer, Buyer Parent or Seller, shall survive the
Closing Date and shall remain operative and in full force and effect for a
period of one (1) year following the Closing Date, except insofar as an
indemnification claim has been asserted by any party and has not been
resolved prior to the end of such one-year period; PROVIDED, HOWEVER, that
the representations and warranties of Seller set forth in Section 2.5 shall
survive for the period of the applicable statute of limitations (if such
statute of limitations is in excess of one (1) year),

                                       26
<Page>

and the respective representations, warranties, covenants and agreements of
Buyer, Buyer Parent and Seller contained in Sections 1.4, 1.7, 1.8, 2.18, 3.4
and 3.6 and in Sections 6, 7 and 8 shall continue without any time limitation.

                  (b)      TERMINATION. This Agreement shall terminate and be
of no further force and effect upon the earlier to occur of (i) at the
election of Buyer or Seller, at any time on or after November 4 , 2001, if
the Closing shall not have occurred by such date (so long as the failure of
the Closing to occur shall not result primarily from the electing party's
failure to comply with this Agreement or a breach of its representations and
warranties hereunder) or (ii) the mutual written consent of Buyer and Seller.
Upon termination, all rights and obligations of the parties hereunder shall
terminate without any liability of any Party, provided that Section 8 shall
survive.

Confidentiality Agreement between Buyer, Buyer Parent and Seller dated June
6, 2001 (which shall remain in full force and effect and govern all
confidential information provided by the Seller to Buyer pursuant to this
Agreement), this Agreement (i) sets forth the entire agreement of the parties
respecting the subject matter hereof, (ii) supersedes any prior and
contemporaneous understandings, agreements, or representations by or among
the parties, written or oral, to the extent they related in any way to such
subject matter, and (iii) may not be amended orally, and no right or
obligation of any party may be altered, except as expressly set forth in a
writing signed by each party hereto.

         8.6.     COUNTERPARTS. This Agreement may be executed in any number

         8.11.    CONFIDENTIALITY. The Seller will (i) treat and hold as
confidential any and all information concerning the businesses and affairs of
the CSC Operations other than that information which is already generally or

refrain from using any of the Confidential Information except in connection
with this Agreement, and (iii) deliver promptly to the Buyer or destroy, at

the event that the Seller is requested or required (by oral question or
request for information or documents in any legal proceeding, interrogatory,
subpoena, civil investigative demand, or similar process) to disclose any
Confidential Information, the Seller will notify the Buyer promptly of the
request or requirement so that the Buyer or the Buyer's Parent may seek an
appropriate protective order or waive compliance with the provisions of this
Section 8.11. If, in the absence of a protective order or the receipt of a
waiver hereunder, the Seller is compelled to disclose any Confidential
Information to any tribunal or else stand liable for contempt, the Seller may
disclose the Confidential Information to the tribunal; PROVIDED, HOWEVER,
that the Seller shall use its reasonable best efforts to obtain, at the
request of the Buyer or the Buyer's Parent, an order or other assurance that
confidential treatment will be accorded to such portion of the Confidential
Information required to be disclosed, as the Buyer or the Buyer's Parent
shall designate.

with respect to the preparation of this Agreement and the consummation of the
transactions contemplated hereby.

confer any rights or remedies upon any person other than the parties hereto
and their respective successors and assigns.

that the Seller will not comply with the provisions of any bulk transfer laws
of any jurisdiction in connection with the transactions contemplated by this
Agreement and waive such compliance.
