corporate power and authority to own, lease and operate its properties and to
conduct the business in which it is engaged as presently conducted. Each of the
Company and its Subsidiaries (as defined in Section 2.4) is duly qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
where the character of the property owned, leased or operated by it, or the
conduct of its business, makes such qualification necessary, except where the
failure to be so duly qualified and in good standing would not reasonably be
expected to have a Material Adverse Effect. As used herein, the term "MATERIAL
ADVERSE EFFECT" means any material adverse effect (i) on the business,
operations, financial condition, results of operations or prospects of the
Company and its Subsidiaries, taken as a whole, (ii) on the ability of the
Company to consummate the transactions contemplated hereby, or (iii) on the
ability of the Company and its Subsidiaries to continue to operate their

prepared by the Company and delivered to the Investors (the "DISCLOSURE
SCHEDULE") contains true, complete and correct copies of the Company's
Certificate of Incorporation (the "CERTIFICATE OF INCORPORATION") and Bylaws
(the "BYLAWS") and the organizational documents of each Subsidiary, in each case
as in effect on the date of this Agreement.

     2.2. Authorization and Enforceability. The Company has full corporate power
and authority to execute and deliver this Agreement, the certificates
representing the Shares, the Investor Rights Agreement, of even date herewith,
by and among the Company, ValueAct, ValueAct II and VCI (the "INVESTOR RIGHTS
AGREEMENT"), the Voting Agreement, of even date herewith, by and among the
Company, ValueAct, ValueAct II and VCI (the "VOTING AGREEMENT") and each other
document or instrument contemplated as being executed and delivered by the
Company under this Agreement (collectively, the "TRANSACTION DOCUMENTS"), to
perform its obligations hereunder and thereunder, and to consummate the
transactions contemplated hereby and thereby. The execution and delivery by the
Company of this Agreement and each other Transaction Document to be executed by
it in connection herewith, and the consummation of the transactions contemplated
hereby and thereby, have been duly and validly authorized by all necessary
corporate action on the part of the Company, and were unanimously approved by
the Board of Directors of the Company. Each of this Agreement and each other
Transaction Document to be executed by the Company in connection herewith has
been duly executed and delivered by the Company, and, when duly executed and
delivered by the other parties hereto or thereto, shall constitute a legal,
valid and binding obligation of the Company, enforceable against it in
accordance with its terms.

terms, conditions or provisions of any (i) note, bond, mortgage, indenture,

Common Stock are issued and outstanding, all of which are duly authorized,
validly issued, fully paid and nonassessable, (ii) no shares of Common Stock are

Agreement, dated November 2, 1998 between the Company and BankBoston, N.A. (the

deemed to be an "Acquiring Person" under the Rights Agreement, (2) result in,

encumbrances, claims, security interests, mortgages, pledges, charges,
conditional sales or other title retention agreements, preemptive rights,
easements, covenants, licenses, options, rights of first refusal or offer, title
defects, or claims of any kind whatsoever (collectively, "LIENS"), other than
restrictions on transfer arising under the Securities Act and any applicable
state securities laws.

shares of capital stock of the Company or any Subsidiary, (iii) granting, or
obligating the Company or any Subsidiary to grant, to any person any preemptive

will be as set forth in Section 2.5(e) of the Disclosure Schedule.

          (f) The Shares, when issued, sold and delivered in compliance with the
provisions of this Agreement and the other Transaction Documents, will be duly
and validly issued, fully paid and nonassessable, with only limited liability
attaching to the ownership thereof under applicable state law. The Shares will

preemptive rights or other restrictions on transfer.

     2.6. Financial Statements. The financial statements of the Company and the
related notes in the SEC Documents, as defined below in Section 2.22, were

the periods covered thereby, except as disclosed in the SEC Documents.

     2.7. Litigation. Neither the Company nor its counsel have been served or
otherwise notified of any pending or threatened claim, arbitration proceeding,
action, suit, investigation or other proceeding. To the knowledge of the
Company, there is no threatened claim, arbitration proceeding, action, suit,
investigation or other proceeding, against or involving the Company or any
Subsidiary, or any of the property or rights of the Company or any Subsidiary,
other than such claims, arbitrations, proceedings, actions, suits,
investigations or other proceedings which, individually or in the aggregate,
would or could reasonably be expected to have a Material Adverse Effect. Neither
the Company nor any Subsidiary is subject to or bound by any order, judgment,
writ, injunction or decree of any federal, state, local or foreign governmental
or regulatory entity (or any department, agency, authority or political
subdivision thereof) or court or arbitrator (any of the foregoing, an


                                     - 5 -
<PAGE>

"AUTHORITY"). The foregoing includes any action, suit, proceeding, or
investigation pending or, to the knowledge of the Company, currently threatened
involving the prior employment of any of the Company's or any Subsidiary's
employees, their use in connection with the Company's or any Subsidiary's
business of any information or techniques allegedly proprietary to any of their
former employers, their obligations under any agreements with prior employers,
or negotiations by the Company or any Subsidiary with potential backers of, or
investors in, the Company or its current or proposed business. There is no
action, suit, proceeding or investigation by the Company or any Subsidiary
pending or that the Company or any Subsidiary intends to initiate.

     2.8. No Brokers or Finders. Except as set forth in Section 2.8 of the
Disclosure Schedule, neither the Company, nor any Subsidiary nor any officers,
directors or employees of the Company or any Subsidiary, nor to the knowledge of
the Company, any affiliate (as defined below) of the Company or any Subsidiary,
(a) has employed (or will employ) any investment banker, broker or finder, or
(b) has incurred (or will incur) any liability for any brokerage fees,
commissions or finders fees or expenses or indemnification or similar
obligations in connection with the transactions contemplated by this Agreement.

          (a) Each of the Company and each Subsidiary has (i) timely filed all
material Tax Returns required to be filed by it, (ii) paid all Taxes required to
be paid with respect to such Tax Returns and (iii) paid all other Taxes for
which a notice of assessment or written demand for payment has been received,
except for Taxes which the Company is contesting in good faith and for which
adequate reserves are established on the financial statements of the Company.
All Tax Returns have been accurately prepared in all material respects and are
true, correct and complete in all material respects. The accruals for Taxes
contained in the balance sheet included in the Interim Financial Statements are
adequate to cover all material liabilities for Taxes of the Company and its
Subsidiaries for all periods ending on or before the date of the Interim
Financial Statements and include adequate provision for all material deferred
Taxes, and nothing has occurred subsequent to that date to make any of such
accruals inadequate in any material respect. All Taxes of the Company and its
Subsidiaries for periods after the date of such balance sheet have been paid or
are adequately reserved against on the books of the Company and its
Subsidiaries. True copies of federal and state income tax returns of the Company
for each of the last five fiscal years have been made available to the
Investors.

          (b) There are no proposed assessments of Taxes against the Company or
any Subsidiary, no proposed adjustments to any Tax Return pending against the
Company or any Subsidiary, and no proposed adjustments to the manner in which
any Tax of the Company or any Subsidiary is determined. Neither the Company nor
any Subsidiary is currently the subject of an audit, examination or similar
proceeding with respect to Taxes (a "TAX PROCEEDING") and, to the Company's
knowledge, no Tax Proceeding is threatened against the Company or a Subsidiary.


                                     - 6 -
<PAGE>

          (c) Neither the Company nor any Subsidiary has made or is obligated to
make any payment which would be an excess parachute payment for purposes of
Section 280G of the Code. Neither the Company nor any Subsidiary is a party to a
Tax allocation or a Tax sharing agreement pursuant to which it could be
responsible for the Taxes of any other person (other than the Company or a
Subsidiary).

          (d) For purposes of this Agreement, "CODE" means the Internal Revenue
Code of 1986, as amended, and any applicable predecessor or successor statute;
"TAXES" means all federal, state, local and foreign income, payroll,
withholding, excise, sales, use, real and personal property, use and occupancy,
business and occupation, mercantile, real estate, capital, franchise and other
taxes of any kind whatsoever, including interest and penalties thereon and all
estimated taxes; and "TAX RETURNS" means all returns or reports, including
accompanying schedules, with respect to Taxes. For purposes of this Section 2.9,
each reference to the Company or any Subsidiary includes any predecessor entity
of the Company or such Subsidiary or any predecessor consolidated, combined or
unitary group of corporations for which the Company or any Subsidiary may be
jointly or severally liable for the Tax Liabilities.

     2.10. Absence of Undisclosed or Contingent Liabilities. Except as set forth
in Section 2.10 of the Disclosure Schedule and except as (and to the extent)
accrued on the most recent audited balance sheet included in the audited
financial statements dated June 30, 2000 and contained in the SEC Documents (the
"AUDITED FINANCIAL STATEMENTS"), as of the date of the most recent balance sheet
included in the Audited Financial Statements, to the knowledge of the Company,
neither the Company nor any Subsidiary had any material liability or obligation
(whether absolute or contingent, liquidated or unliquidated), other than

otherwise has the right to use, and has the right to bring actions for the

(other than standard, commercially available off-the-shelf software), domain
names, and other intellectual property necessary for the operation of business
of the Company and any Subsidiary as it is currently conducted and as proposed
to be conducted (the "INTELLECTUAL PROPERTY"). None of the Company, any

<PAGE>

arisen to that effect. Neither the Company nor any applicable Subsidiary has any
pending claims that a third party has violated or infringed any of the Company's
patents, industrial design rights, trademarks, service marks, trade names, trade
dress, copyrights, trade secrets or other proprietary rights. Except as set
forth in Section 2.12(b) of the Disclosure Schedules, neither the Company nor
any applicable Subsidiary has given any indemnification to any third party
against infringement of such intellectual property rights.

          (c) All of the patents, industrial design registrations, trademark and
service mark registrations, copyright registrations, mask work registrations and
domain name registrations comprising the Intellectual Property are in full force
and effect, are held of record in the name of the Company or the applicable
Subsidiary free and clear of all liens, encumbrances and other claims, and are
not the subject of any cancellation or reexamination proceeding or any other
proceeding challenging their extent or validity. The Company or the applicable
Subsidiary is the applicant of record in all patent applications, and
applications for trademark, service mark, trade dress, industrial design,
copyright, mask work and domain name registration that comprise the Intellectual
Property, and no opposition, extension of time to oppose, interference,

          (d) To the extent that any works of authorship, materials, products,
inventions, technology or software have been developed or created independently
or jointly by any person other than the Company or any Subsidiary, or an
employee of the Company or any Subsidiary other than pursuant to such employee's
regular, salaried responsibilities to the Company and/or Subsidiary, and for
which the Company or any Subsidiary has, directly or indirectly, paid, the
Company or the applicable Subsidiary has a written agreement with such person
with respect thereto, and the Company or the applicable Subsidiary thereby has
obtained ownership of, and is the exclusive owner of, all Intellectual Property
therein or thereto by operation of law or by valid assignment. In each case in
which either the Company or any Subsidiary has acquired any Intellectual
Property from any person, the Company or the applicable Subsidiary has obtained
a valid and enforceable assignment sufficient to irrevocably transfer all rights
in such Intellectual Property (including the right to seek past and future
damages with respect thereto) to the Company or the applicable Subsidiary and,
to the maximum extent provided for by, and in accordance with, any applicable
laws and regulations, the Company has recorded each such assignment with the
relevant governmental authorities, including the U.S. Patent and Trademark
Office, the U.S. Copyright Office, or their respective equivalents in any
relevant foreign jurisdiction.

          (e) The Company and each Subsidiary has taken all commercially
reasonable steps that are required to protect the Company's rights in material
trade secrets, know-how or other confidential or proprietary information
(including, without limitation, computer software source code) of the Company
and any Subsidiary or provided by any other person to the Company or any
Subsidiary. Without limiting the foregoing, each of the Company and each
Subsidiary has, and enforces, a policy requiring each employee, consultant and
contractor to execute proprietary information, confidentiality and assignment
agreements substantially in the Company's standard forms, and all current and
former employees, consultants and contractors of the Company or any Subsidiary
have executed such an agreement in substantially the Company's standard form. To
the knowledge of the Company, none of the material trade secrets, know-how or
other confidential or proprietary information of the Company or any Subsidiary
has been disclosed to any person unless such disclosure was necessary, and was
made pursuant to an appropriate confidentiality agreement.

          (f) All computer software currently used in the Business and any
Subsidiary will consistently and accurately interpret, calculate, manipulate,

2001 and any leap year calculations. The computer software used in the Business
does not contain any viruses, "worms", "Trojan Horses", malicious or disabling
code, or other anomalies that would substantially impair the functionality of
such computer software.

     2.13. Permits. Each of the Company and its Subsidiaries possesses all
certificates, permits, franchises, licenses and authorizations ("PERMITS")
required by any Authority having or claiming jurisdiction over the Company or
any such Subsidiary, or their properties or business except where the failure to
have such a Permit would not reasonably be expected to have a Material Adverse
Effect. All such Permits are in full force and effect and good standing in all
material respects. Neither the Company nor any Subsidiary is in material default
(or material non-compliance) under any Permit. No modification, suspension or
cancellation of a Permit, or any proceeding relating thereto, is pending or, to
the knowledge of the Company, threatened with respect to a Permit. No other
proceeding is pending or, to the knowledge of the Company, threatened with
respect to any such Permit. No notice has been received by the Company or any
Subsidiary with respect to any failure by the Company or any Subsidiary to have
any Permit.

     2.14. Compliance with Laws. The operations of the Company and its
Subsidiaries have been conducted in compliance in all material respects with

employment and employment practices, terms and conditions of employment and
wages and hours, antitrust, consumer protection, immigration, health,
occupational safety and health, and securities. The Company has not received any
notification of any asserted present or past failure by the Company or any
Subsidiary to comply with any laws, rules or regulations.

of the Company, any other party to any contract described in the SEC Documents

all material respects complete, current and correct copies of: (a) its
Certificate of Incorporation, Bylaws, and other organizational documents; (b)
its stockholder records; and (c) the minutes, written consents, resolutions and

     2.18. Offering Exemption. Subject to the accuracy of the representations in
Section 3.2 hereof, the offer, sale and issuance of the Shares in conformity
with the terms of this Agreement constitute transactions exempt from the
registration requirements of the Securities Act, and from all applicable state

acting on its behalf will take any action hereafter that would cause the loss of
such exemption. The Company has not offered any Common Stock or any securities
similar to the Common Stock for sale to, or solicited any offers to buy any of
the foregoing from, or otherwise approached or negotiated in respect thereof
with, any person or persons other than a limited number of institutional or
other sophisticated investors deemed to be "accredited investors" (as such terms

offerings were made in compliance with, or exempt from registration under, and
in accordance with, the Securities Act and applicable state securities and "blue
sky" laws.

     2.19. Absence of Questionable Payments. Neither the Company, nor any
Subsidiary nor, to the knowledge of the Company, any of their respective
directors, officers, agents, employees or other person acting on their behalf,
has used any corporate or other funds for unlawful contributions, payments,
gifts, or entertainment, or made any unlawful expenditures relating to political
activity to government officials or others or established or maintained any
unlawful or unrecorded funds. Neither the Company, any Subsidiary nor, to the
knowledge of the Company, any of their respective directors, officers, agents,
employees or other persons acting on their behalf, has accepted or received any
unlawful contributions, payments, gifts, or expenditures.

to be adequate for its business, including, but not limited to, directors and
officers insurance and insurance covering all real and personal property owned
or leased by the Company against theft, damage, destruction, acts of vandalism
and all other risks customarily insured against by similarly situated companies,
all of which insurance is in full force and effect.

to Section 12(g) of the Exchange Act and is listed on The Nasdaq National Market
(the "NASDAQ STOCK MARKET"), and the Company has taken no action designed to, or
likely to have the effect of, terminating the registration of the Common Stock
under the Exchange Act or delisting the Common Stock from the Nasdaq Stock

     2.22. SEC Documents. The Company has timely filed with the Securities and
Exchange Commission (the "SEC") all forms, reports, schedules, statements and
other documents required to be filed with the SEC by the Company since June 1,
1996 (together with all information incorporated therein by reference, the "SEC
DOCUMENTS"). No subsidiary of the Company is required to file any periodic
reports under the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"). As of their respective dates, the SEC Documents complied in all material
respects with the requirements of the Securities Act or the Exchange Act, as the
case may be, and the rules and regulations of the SEC promulgated thereunder
applicable to such SEC Documents, and none of the SEC Documents at the time they
were filed 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. Except to the extent that information contained in any SEC
Document filed and publicly available prior to the date of this Agreement (a
"FILED SEC DOCUMENT") has been revised or superseded by a later Filed SEC
Document, none of the SEC Documents contains any untrue statement of a material
fact or omits 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 financial statements (including
the related notes) included in the SEC Documents comply as to form in all
material respects with applicable accounting requirements and the published
rules and regulations of the SEC with respect thereto, have been prepared in
accordance with GAAP (except, in the case of unaudited statements, as permitted

involved (except as may be indicated in the notes thereto) and fairly present in
all material respects the consolidated financial position of the Company and its
consolidated subsidiaries as of the dates thereof and their consolidated results
of operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal and recurring year-end audit adjustments).

     2.23. Full Disclosure. No representation, warranty or other statement in
any certificate or written statement given to the Investors (including the
representations and warranties contained herein) in connection with the
transactions contemplated hereby by the Company, any Subsidiary or any of their
respective officers, directors, employees, agents or other representatives
contains any untrue statement of material fact or omits to state a material fact
