securities:

            (a) Conversion of Merger Sub Common Stock. Each share of Merger Sub
Common Stock that is issued and outstanding immediately prior to the Effective
Time shall be converted into one validly issued, fully paid and nonassessable
share of Common Stock, $0.001 par value per share, of the Surviving Corporation,
and the shares of the Surviving Corporation into which the shares of Merger Sub
Common Stock are so converted shall be the only shares of the Surviving
Corporation that are issued and outstanding immediately after the Effective
Time. Following the Effective Time, each certificate evidencing ownership of
shares of Merger Sub Common Stock shall evidence ownership of such shares of the
Surviving Corporation.

                                       11


            (b) Conversion of Company Common Stock. Each share of Company Common
Stock (including each Company Restricted Share) that is issued and outstanding
immediately prior to the Effective Time (other than any shares of Company Common
Stock to be canceled pursuant to Section 2.4(e)), will be canceled and
extinguished and automatically converted (subject to Section 2.4(g)) into the
right to receive 1.1242 (the "EXCHANGE RATIO") shares of Parent Common Stock,
upon surrender of the certificate representing such share of Company Common
Stock in the manner provided in Section 2.7. No fraction of a share of Parent
Common Stock will be issued by virtue of the Merger, but in lieu thereof, a cash
payment shall be made pursuant to Section 2.4(f). Notwithstanding the foregoing,
Company Restricted Shares shall be subject to the provisions of Section 2.5.

            (c) Conversion of Company Special Voting Share. The Company Special
Voting Share that is issued and outstanding immediately prior to the Effective
Time will be canceled and extinguished and automatically converted into the
right to receive one Parent Special Voting Share. As of the Effective Time, such
Company Special Voting Share shall no longer be outstanding and shall
automatically be canceled and shall cease to exist, and the holder of a
certificate which, prior to the Effective Time, represented such Company Special
Voting Share shall cease to have any rights or powers with respect thereto,
except the right to receive the Parent Special Voting Share.

            (d) Company Options and Restricted Stock Units.

                  (1) Assumed Company Options. Unless the terms of an agreement
evidencing a Company Option or the provisions of a Company Option Plan
applicable to a Company Option provide otherwise, each Company Option that is
issued and outstanding immediately prior to the Effective Time, whether or not
then exercisable, with an exercise price equal to or less than $49.00, will be
assumed by Parent and converted into an option to purchase Parent Common Stock
("ASSUMED COMPANY OPTIONS"). Each Company Option so assumed and converted will
continue to have, and be subject to, the same terms and conditions, except that
(i) each converted Company Option shall be exercisable (or will become
exercisable in accordance with its terms) for that number of whole shares of
Parent Common Stock equal to the product of the number of shares of Company
Common Stock that were issuable upon exercise of such Company Option immediately
prior to the Effective Time multiplied by the Exchange Ratio (rounded down to
the nearest whole share) and (ii) the per share exercise price for the shares of
Parent Common Stock issuable upon exercise of such converted Company Option
shall be equal to the quotient determined by dividing the exercise price per
share of Company Common Stock at which such Company Option was exercisable
immediately prior to the Effective Time by the Exchange Ratio (rounded up to the
nearest whole cent). The conversion of Company Options provided for in this
Section 2.4(d)(1) with respect to any Company Options that are intended to be
"incentive stock options" (as defined in Section 422 of the Code) shall be
effected in a manner consistent with Section 424(a) of the Code and otherwise in
a manner designed to preserve incentive stock option treatment to the extent
permitted by Applicable Law.

                  (2) Cancellation of Certain Company Options. Each Company
Option that is issued and outstanding immediately prior to the Effective Time,
whether or not then exercisable, which is not an Assumed Company Option and
which is not exercised as of immediately prior to the Effective Time, shall be
canceled and extinguished without any conversion or assumption thereof
immediately prior to the Effective Time.

                                       12


                  (3) Consistent Treatment of Certain Company Options.
Notwithstanding the provisions of Section 2.4(d)(1) and Section 2.4(d)(2), if
certain Company Options are subject to the express terms of a Company Option
Plan that require all Company Options granted under such Company Option Plan to
be treated in the same manner, then all such Company Options, whether or not
then exercisable and regardless of the exercise price of such Company Options,
shall be assumed by Parent and converted into an option to purchase Parent
Common Stock in accordance with the last two sentences of Section 2.4(d)(1).

                  (4) Company Restricted Stock Units. Each Company Restricted
Stock Unit that is issued and outstanding immediately prior to the Effective
Time will be assumed by Parent and converted into a Parent Restricted Stock
Unit. Each Company Restricted Stock Unit so assumed and converted will continue
to have, and be subject to, the same terms and conditions, except that each
converted Company Restricted Stock Unit shall be for that number of whole shares
of Parent Common Stock equal to the product of the number of shares of Company
Common Stock that were subject to the Company Restricted Stock Unit immediately
prior to the Effective Time multiplied by the Exchange Ratio (rounded down to
the nearest whole share).

            (e) Cancellation of Company-Owned and Parent-Owned Stock. Each share
of Company Common Stock held by Company or owned by Merger Sub, Parent or any
direct or indirect wholly-owned Subsidiary of Parent immediately prior to the
Effective Time shall be canceled and extinguished without any conversion
thereof.

            (f) Fractional Shares. No fraction of a share of Parent Common Stock
will be issued by virtue of the Merger or any exchange of an Exchangeable Share
at any time after the Effective Time, but in lieu thereof each former holder of
shares of Company Common Stock who would otherwise be entitled to a fraction of
a share of Parent Common Stock (after aggregating all fractional shares of
Parent Common Stock that otherwise would be received by such holder) shall, upon
surrender of such holder's Certificate(s) (as defined in Section 2.7(c)),
receive from Parent an amount of cash in U.S. dollars (rounded to the nearest
whole cent), without interest, less the amount of any withholding taxes with
respect to the shares represented by such certificate as contemplated by Section
2.8(b), which are required to be withheld with respect thereto, equal to the
product of (i) such fraction, multiplied by (ii) the closing sale price of one
share of Parent Common Stock as quoted on the Nasdaq Stock Market for the
trading day that is one trading day prior to the Closing Date (the "FRACTION
PRICE"). In lieu of any such fractional interests, each holder of Exchangeable
Shares exchanged pursuant to the provisions thereof who would otherwise have
been entitled to receive a fraction of a share of Parent Common Stock (after
taking into account all shares of Parent Common Stock to which such holder is
entitled pursuant to Section 2.4 and the provisions of the Exchangeable Shares)
shall be entitled to receive an amount of cash in U.S. dollars (rounded to the
nearest whole cent), without interest, equal to the product of such fraction
multiplied by the Fraction Price.

            (g) Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect appropriately the effect of any stock split, reverse stock
split, stock dividend (including any dividend or distribution of securities
convertible into Parent Common Stock or Company Common Stock), reorganization,
recapitalization, reclassification or other like change with respect to Parent
Common Stock or Company Common Stock occurring on or after the Agreement Date
and prior to the Effective Time.

                                       13


      2.5 Company Restricted Shares. Subject to the terms of any agreement
entered into prior to the Agreement Date (a correct and complete copy of which
has been disclosed and made available to Parent), the shares of Parent Common
Stock issued upon the conversion of any Company Restricted Shares in the Merger
will continue to be unvested and subject to the same repurchase options, risks
of forfeiture or other conditions following the Effective Time, and the
certificates representing such shares of Parent Common Stock may accordingly be
marked with appropriate legends noting such repurchase options, risks of
forfeiture or other conditions. The Company shall take all actions that may be
necessary to ensure that, from and after the Effective Time, Parent is entitled
to exercise any such repurchase option or other right set forth in any Contract
governing Company Restricted Shares.

      2.6 Treatment of Exchangeable Shares.

            (a) Prior to the Effective Time, the Boards of Directors of each of
the Company, Parent and Canadian Sub, or any of their respective appropriate
committees, shall adopt appropriate resolutions and, along with the Company,
Parent and Canadian Sub, shall take all other actions required under the Old
Voting, Support and Exchange Trust Agreement to ensure that following the
Effective Time, the rights of the holders of Exchangeable Shares are
"economically equivalent" to the rights enjoyed by such holders prior to such
time within the meaning of the Old Voting, Support and Exchange Trust Agreement.
In this regard, and without limiting the generality of the foregoing,
immediately following the Effective Time, each outstanding Exchangeable Share
shall be exchangeable for such number of shares of Parent Common Stock as is
determined by reference to the following formula:

                  A x B

                  where:

                  "A" equals the Exchange Ratio, and

                  "B" equals 4.5,

unless further adjustment is then required pursuant to the rights, privileges,
conditions and restrictions attaching to the Exchangeable Shares, plus payment
of the "Dividend Amount" (as such term is defined in such rights, privileges,
conditions and restrictions), if any.

            (b) Without limiting the generality of Section 2.6(a), the parties
agree as follows:

                  (1) At or before the Effective Time, the Company and Canadian
Sub (including its Board of Directors) shall comply with their respective
obligations under the provisions attaching to the Exchangeable Shares and the
Old Voting, Support and Exchange Trust Agreement.

                  (2) At or before the Effective Time, Parent, the Company,
Canadian Sub and the Trustee shall execute and deliver the Voting, Support and
Exchange Trust Supplement wherein the Parent agrees to be bound by the terms and
provisions of the Old Voting, Support and Exchange Trust Agreement, in a form
satisfactory to the Trustee, and, to the

                                       14


satisfaction of the Trustee, preserving and not impairing in any material
respect, any of the rights, duties, powers and authorities of the Trustee or the
holders of Exchangeable Shares under the Old Voting, Support and Exchange Trust
Agreement.

                  (3) At or before the Effective Time, Parent shall have
authorized the Parent Special Voting Share and at the Effective Time, Parent
shall deliver to the Trustee a new certificate evidencing the Parent Special
Voting Share, to the extent required by the Voting, Support and Exchange Trust
Supplement.

                  (4) At or before the Effective Time, Parent, the Company and
Canadian Sub shall take all such actions as may reasonably be required to:

                        (i) permit the continued unrestricted and free
tradability in Canada of the Exchangeable Shares (other than restrictions on
transfers by control block holders) in those Provinces and Territories of Canada
in which such securities were unrestricted and freely tradable immediately prior
to the Effective Time;

                        (ii) ensure that the Exchangeable Shares remained listed
and posted for trading on the Toronto Stock Exchange;

                        (iii) obtain all such qualifications, registrations,
approvals, orders, rulings, or consents, make all such filings, fulfill all such
legal or regulatory requirements and take all such other proceedings as are
necessary or are required under any Canadian or United States federal,
provincial or state law or regulation or pursuant to the rules and regulations
of any other regulatory authority of competent jurisdiction, in order to ensure
that following the Effective Time, shares of Parent Common Stock can be issued
by the Parent to holders of Exchangeable Shares on exercise of the exchange
rights attached to such securities, and thereafter, to ensure that such
securities will be freely tradable by such holders in the United States (other
than restrictions on transfer by reason of the holder being a "control person"
or an "affiliate" of the Parent); and

                        (iv) ensure that the shares of Parent Common Stock are
listed, quoted or posted for trading on the Nasdaq Stock Market.

Without limiting the generality of the foregoing, such actions shall include the
confirmation of the continued effectiveness, following the Merger, of all
existing Canadian securities regulatory orders and rulings, or the granting of
new such orders and rulings, respecting such unrestricted and free tradability
of the Exchangeable Shares in the above-noted Provinces and Territories of
Canada and such unrestricted issuance of the shares of Parent Common Stock
issuable upon exchange of the Exchangeable Shares from time to time and the
resale of same in the United States, and respecting the satisfaction of Canadian
Sub's Canadian securities law continuous and timely disclosure obligations
through the filing and provision of information relating to Parent.

                  (5) At or before the Effective Time, Parent shall take all
action necessary to authorize and irrevocably reserve for issuance, free from
preemptive and other rights, out of its authorized and unissued capital stock
that number of shares of Parent Common Stock sufficient for issuance upon
exercise of the exchange rights attaching to all of the

                                       15


Exchangeable Shares (other than Exchangeable Shares held by Parent, its
Subsidiaries and Affiliates) outstanding from time to time after the Effective
Time.

                  (6) At or before the Effective Time, Parent, the Company and
Canadian Sub shall take all action necessary to provide to holders of
Exchangeable Shares, an alternative retraction mechanism that will allow such
holders to retract their shares (thereby requiring the Canadian Sub to redeem
same) conditional upon the completion of the Merger.

      2.7 Exchange of Certificates.

            (a) Exchange Agent. Parent shall select an institution reasonably
acceptable to the Company to act as the exchange agent (the "EXCHANGE AGENT") in
the Merger and shall enter into an exchange agent agreement with the Exchange
Agent reasonably satisfactory to Company.

            (b) Exchange Fund. Promptly after the Effective Time, Parent shall
make available to the Exchange Agent for exchange in accordance with this
Article 2, the shares of Parent Common Stock and cash in lieu of fractional
shares (together with any dividends or distributions with respect thereto, the
"EXCHANGE FUND") issuable pursuant to Section 2.4(b) and Section 2.4(e) in
exchange for outstanding shares of Company Common Stock.

            (c) Exchange Procedures. Promptly after the Effective Time, Parent
shall instruct the Exchange Agent to mail to each holder of record of a
certificate or certificates ("CERTIFICATES") which immediately prior to the
Effective Time represented outstanding shares of Company Common Stock whose
shares were converted into the right to receive shares of Parent Common Stock
pursuant to Section 2.4(b), cash in lieu of any fractional shares pursuant to
Section 2.4(f) and any dividends or other distributions pursuant to Section
2.7(d), (i) a letter of transmittal in customary form (that shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Exchange Agent) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of Parent Common Stock. Upon
surrender of Certificates for cancellation to the Exchange Agent together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, and such other documents as may reasonably be
required by the Exchange Agent (including any required Form W-9 or Form W-8),
the holders of such Certificates shall be entitled to receive in exchange
therefor certificates representing the number of whole shares of Parent Common
Stock (after aggregating all Certificates surrendered by such holder) into which
such holder is entitled pursuant to Section 2.4(b) (which shall be in
uncertificated book entry form unless a physical certificate is requested or
required by Applicable Law or regulation), a check in the amount of U.S. dollars
in lieu of fractional shares that such holders have the right to receive
pursuant to Section 2.4(f) and any dividends or distributions payable pursuant
to Section 2.7(d), and the Certificates so surrendered shall forthwith be
canceled. Until so surrendered, outstanding Certificates will be deemed from and
after the Effective Time, for all corporate purposes, to evidence only the right
to receive upon surrender thereof the number of whole shares of Parent Common
Stock to which such holder is entitled pursuant to Section 2.4(b), an amount in
cash in lieu of the issuance of any fractional shares in accordance with Section
2.4(f) and any dividends or distributions payable pursuant to Section 2.7(d). No
interest will be paid or accrued on any cash payable in lieu of fractional
shares of Parent Common Stock or on any unpaid dividends or

                                       16


distributions payable to holders of Certificates. In the event of a transfer of
ownership of shares of Company Common Stock that is not registered in the
transfer records of the Company, a certificate representing the proper number of
shares of Parent Common Stock and cash payable in lieu of fractional shares may
be issued to a transferee if the Certificate representing such shares of Company
Common Stock is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid.

            (d) Distributions With Respect to Unexchanged Shares. No dividends
or other distributions declared or made after the Agreement Date with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holders of any unsurrendered Certificates with respect to the shares of
Parent Common Stock represented thereby until the holders of record of such
Certificates shall surrender such Certificates. Subject to Applicable Law,
following surrender of any such Certificates, the Exchange Agent shall deliver
to the record holders thereof, without interest, (i) promptly after such
surrender, the amount of any cash payable with respect to a fractional share of
Parent Common Stock to which such holder is entitled pursuant to Section 2.4(f)
and the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to the whole shares of Parent
Common Stock represented thereby, and (ii) at the appropriate payment date, the
amount of dividends or other distributions with a record date after the
Effective Time but prior to surrender and a payment date occurring after
surrender, payable with respect to such whole shares of Parent Common Stock.

            (e) Lost, Stolen or Destroyed Certificates. In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue and pay in exchange for such lost, stolen or destroyed Certificates, upon
the making of an affidavit of that fact by the holder thereof, certificates
representing the shares of Parent Common Stock into which the shares of Company
Common Stock represented by such Certificates were converted pursuant to Section
2.4(b), cash for fractional shares, if any, as may be required pursuant to
Section 2.4(f) and any dividends or distributions payable pursuant to Section
2.7(d); provided, however, that Parent or the Exchange Agent may, in its
discretion and as a condition precedent to the issuance of such certificates
representing shares of Parent Common Stock, cash and other distributions,
require the owner of such lost, stolen or destroyed Certificates to deliver a
bond in such sum as it may reasonably direct as indemnity against any claim that
may be made against Parent, the Surviving Corporation or the Exchange Agent with
respect to the Certificates alleged to have been lost, stolen or destroyed.

            (f) Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the former holders of Company Common Stock for
one year after the Effective Time shall be delivered to Parent, upon demand, and
any such holders of Company Common Stock who have not theretofore complied with
the provisions of this Section 2.7 shall thereafter look only to Parent for the
shares of Parent Common Stock to which they are entitled pursuant to Section
2.4(b), any cash in lieu of fractional shares of Parent Common Stock to which
they are entitled pursuant to Section 2.4(f) and any dividends or other
distributions with respect to Parent Common Stock to which they are entitled
pursuant to Section 2.7(d), in each case without any interest thereon.

                                       17


            (g) No Further Ownership Rights in Company Common Stock. All shares
of Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock
and dividends or other distributions with respect to Parent Common Stock issued
in accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Company Common Stock that were outstanding
immediately prior to the Effective Time. If after the Effective Time
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article 2.

            (h) No Liability. Notwithstanding anything to the contrary in this
Section 2.7, neither the Exchange Agent, Parent, the Company, the Surviving
Corporation nor any party hereto shall be liable to a holder of shares of
Company Common Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

      2.8 Tax Consequences and Withholding.

            (a) Consequences. It is intended by the parties hereto that the
Merger shall constitute a "reorganization" within the meaning of Section 368 of
the Code. The parties hereto adopt this Agreement as a "plan of reorganization"
within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States
Income Tax Regulations.

            (b) Withholding. Each of the Exchange Agent, Parent and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
former Company Stockholder such amounts as may be required to be deducted or
withheld therefrom under the Code or under any provision of state, local or
foreign tax law or under any other Applicable Law. To the extent such amounts
are so deducted and withheld, such amounts shall be treated for all purposes
under this Agreement as having been paid to the Person in respect of whom such
deduction and withholding was made.

      2.9 Further Assurances. If, at any time before or after the Effective
Time, the Company or Parent reasonably believes or is advised that any further
instruments, deeds, assignments or assurances are reasonably necessary or
desirable to consummate the Merger or to carry out the purposes and intent of
this Agreement at or after the Effective Time, then the Company, Parent, the
Surviving Corporation and their respective officers and directors shall execute
and deliver all such proper deeds, assignments, instruments and assurances and
do all other things reasonably necessary or desirable to consummate the Merger
and to carry out the purposes and intent of this Agreement.

                                    ARTICLE 3
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      Except as set forth in the disclosure letter of the Company addressed to
Parent, dated as of the Agreement Date and delivered to Parent concurrently with
the parties' execution of this Agreement (the "COMPANY DISCLOSURE LETTER")
referencing a representation or warranty herein (it being understood that the
Company Disclosure Letter shall be arranged in sections and

                                       18


subsections corresponding to the sections and subsections contained in this
Agreement, and the disclosures in any section or subsection of the Company
Disclosure Letter shall qualify all of the applicable representations and
warranties in the corresponding section or subsection of this Article 3 and, in
addition, in all other sections or subsections in this Article 3 to the extent
it is reasonably apparent from the text of such disclosure that that such
disclosure is applicable to such other sections or subsections), the Company
represents and warrants to Parent as follows:

      3.1 Organization.

            (a) Standing and Power. Each of the Company and its Subsidiaries (i)
is a corporation or other entity duly organized, validly existing and in good
standing (with respect to jurisdictions which recognize such concept) under the
laws of the jurisdiction of its incorporation or organization, (ii) has the
requisite power and authority to own, lease and operate its properties and to
carry on its business as currently conducted, and (iii) is duly qualified or
licensed to do business, and is in good standing (with respect to jurisdictions
which recognize such concept), in each jurisdiction where the character of the
properties owned, leased or operated by it or the nature of its activities makes
such qualification or licensing necessary, in each case except as would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the Company.

            (b) Charter Documents. The Company has made available to Parent or
filed with the SEC prior to the Agreement Date: (i) a complete and correct copy
of the Certificate of Incorporation (including any Certificates of Designation)
and Bylaws of the Company, each as amended to date, and (ii) a complete and
correct copy of the articles or certificate of incorporation and bylaws (or like
organizational documents), each as amended to date, of each of its Significant
Subsidiaries (collectively with the documents identified in the preceding clause
(i), the "COMPANY CHARTER DOCUMENTS"), and each such instrument is in full force
and effect. Neither Company nor any of such Subsidiaries is in violation of any
of its Company Charter Documents, except in the case of such Significant
Subsidiaries as would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect on the Company.

            (c) Subsidiaries. Schedule 3.1(c) of the Company Disclosure Letter
sets forth a list of each Subsidiary of the Company. All the outstanding shares
of capital stock of, or other equity or voting interests in, each Significant
Subsidiary of the Company (i) are owned directly or indirectly by the Company,
free and clear of all Encumbrances (except for Permitted Encumbrances and
restrictions imposed by applicable securities laws), (ii) are not subject to any
preemptive right or right of first refusal created by Applicable Law, the
Company Charter Documents or any Contract to which such Significant Subsidiary
is a party or by which it is bound, and (iii) are duly authorized, validly
issued, fully paid and nonassessable. Other than the Subsidiaries of the
Company, as of the Agreement Date, neither the Company nor any of its
Subsidiaries owns any capital stock of, or other equity or voting interests of
any nature in, or any interest convertible, exchangeable or exercisable for,
capital stock of, or other equity or voting interests of any nature in, any
other Person where the aggregate book value reflected on the Company Balance
Sheet (or the cost to the Company and its Subsidiaries with respect to
securities acquired after September 30, 2004) of all such securities issued by
any single Person exceeds $5,000,000. As of the Agreement Date, there are no
outstanding obligations of the Company or any of its Subsidiaries under any
Contract to which it is a party or by which it is otherwise bound to make any
loan to, or any equity or other investment (in the form of a capital

                                       19


contribution or otherwise) in any other Person (other than the Company or such a
Subsidiary) in an amount in excess of $5,000,000 in respect of any single
Person.

      3.2 Capitalization of the Company.

            (a) Capital Stock. The authorized capital stock of the Company
consists solely of 2,000,000,000 shares of Company Common Stock, 10,000,000
shares of Company Preferred Stock, of which 10,000,000 shares have been
designated Series A Junior Participating Preferred Stock and reserved for
issuance upon exercise of the Company Rights, and one Company Special Voting
Share. As of the close of business on December 13, 2004, (i) 423,071,486 shares
of Company Common Stock were issued and outstanding (ii) no Company Restricted
Shares were issued and outstanding, (iii) 22,958,527 shares of Company Common
Stock were held in treasury by the Company and its Subsidiaries, (iv) no shares
of Company Preferred Stock were issued or outstanding, (v) one Company Special
Voting Share was issued and outstanding and (vi) 58,770 Exchangeable Shares were
issued and outstanding. From December 13, 2004 through the Agreement Date, no
shares of Company Common Stock have been issued by the Company or any Subsidiary
of the Company other than pursuant to the exercise of Company Options that were
outstanding on December 13, 2004 or the exchange of Exchangeable Shares that
were outstanding on December 13, 2004. The Company Special Voting Share entitles
the holder thereof to vote, together with the holders of Company Common Stock,
on all matters submitted for the vote of the holders of Company Common Stock.
The number of votes represented by the Company Special Voting Share is equal to
the number of outstanding Exchangeable Shares (other than Exchangeable Shares
held by the Company, its Subsidiaries and its Affiliates). All issued and
outstanding shares of Company Common Stock have been duly authorized and validly
issued, are fully paid and nonassessable, and are not subject to preemptive
rights created by Applicable Law, the Company Charter Documents or any Contract
to which the Company is a party or by which it is bound.

            (b) Stock Options, Purchase Plans, Restricted Stock Units and
Convertible Securities. As of the close of business on December 13, 2004, (i)
65,088,225 shares of Company Common Stock were subject to issuance pursuant to
outstanding Company Options under the Company Option Plans, (ii) 2,531,505
shares of Company Common Stock were subject to issuance pursuant to outstanding
Company Options outside the Company Option Plans, (iii) 19,543,076 shares of

Company.

                                       22


            (f) No Conflict. The execution and delivery of this Agreement by the
Company do not, and the consummation by the Company of the transactions
contemplated hereby and compliance by the Company with the provisions of this

is a party or by which the Company or any of its Subsidiaries is bound, other
than, in the cases of clauses (ii) and (iii), any such conflicts, violations,

which, individually or in the aggregate, would not reasonably be expected to
materially affect the ability of the Company to consummate the Merger or have a
Material Adverse Effect on the Company.

      3.4 SEC Filings.

            (a) SEC Reports. The Company has filed with the SEC all registration

with the requirements of the Securities Act, the Exchange Act, the Sarbanes Act
(to the extent then applicable), and the rules and regulations of the SEC
promulgated thereunder applicable to such Company SEC Documents and (ii) did not
at the time they were filed (or if amended or superseded by a filing prior to
the Agreement Date, then on the date of such filing) contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, except to
the extent corrected prior to the Agreement Date by a subsequently filed Company
SEC Document. None of the Company's Subsidiaries is required to file any forms,
reports or other documents with the SEC.

            (b) Financial Statements. Each of the consolidated financial

of unaudited interim financial statements, as may be permitted by the SEC on
Form 10-Q or Form 8-K) applied on a consistent basis throughout the periods
involved (except as may be indicated in the notes thereto), and (iii) fairly
presented in all material respects the consolidated financial position of
Company and its Subsidiaries as at the respective dates thereof and the
consolidated results of Company's and its Subsidiaries' operations and cash
flows for the periods indicated (except that the unaudited interim financial

adjustments which were not material). Except as reflected in the balance sheet
of the

                                       23


Company dated September 30, 2004 included in the Form 10-Q filed by the Company
with the SEC on November 5, 2004 (the "COMPANY BALANCE SHEET") (or described in
the notes thereto), neither the Company nor any of its Subsidiaries has any
Liabilities of any nature that would be required to be disclosed on a

accordance with GAAP consistently applied, except (i) Liabilities incurred since
September 30, 2004 in the ordinary course of business consistent with past
practice, (ii) Liabilities under a Company Material Contract (as defined in
Section 3.12 below) set forth on Schedule 3.4(b) of the Company Disclosure

Company and the principal financial officer of the Company (or each former
principal executive officer of the Company and each former principal financial
officer of the Company, as applicable) has made all certifications required by
Rule 13a-14 or Rule 15d-14 under the Exchange Act or Sections 302 and 906 of the
Sarbanes Act and the rules and regulations of the SEC promulgated thereunder
with respect to the Company SEC Documents. For purposes of the preceding
sentence, "principal executive officer" and "principal financial officer" shall
have the meanings given to such terms in the Sarbanes Act.

            (d) Amendments. The Company has heretofore made available to Parent
a complete and correct copy of any amendments or modifications effected prior to
the Agreement Date, which have not yet been filed with the SEC but which are
required to be filed, to agreements, documents or other instruments which
previously had been filed by the Company with the SEC pursuant to the Securities
Act or the Exchange Act.

            (e) Registration Statement. The information supplied by the Company
for inclusion in the Registration Statement shall not at the time the
Registration Statement is filed with the SEC and at the time it becomes
effective under the Securities Act contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein not misleading. The
information supplied by the Company for inclusion or incorporation by reference
in the Proxy Statement/Prospectus shall not, on the date the Proxy
Statement/Prospectus is mailed to Company Stockholders or Parent Stockholders,
at the time of the meeting of Company Stockholders (the "COMPANY STOCKHOLDERS'
MEETING") to consider the Company Stockholder Approval, at the time of the
meeting of Parent Stockholders (the "PARENT STOCKHOLDERS' MEETING") to consider
the Parent Stockholder Approval or as of the Effective Time, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not false or misleading, or omit to
state any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of proxies for the Company
Stockholders' Meeting or the Parent Stockholders' Meeting which has become false
or misleading. The proxy statement included in the Proxy Statement/Prospectus
will comply as to form in all material respects with the provisions of the
Exchange Act and the rules and regulations thereunder. If at

                                       24


any time prior to the Effective Time any event relating to the Company or any of
its Affiliates, officers or directors should be discovered by the Company which
is required to be set forth in an amendment to the Registration Statement or a
supplement to the Proxy Statement/Prospectus, the Company shall promptly inform
Parent. Notwithstanding the foregoing, the Company makes no representation or
warranty with respect to any statements made or incorporated by reference

Company or any of its Subsidiaries before any Governmental Authority, arbitrator
or mediator, nor, to the knowledge of the Company, has any such action, suit,
arbitration, mediation, proceeding, claim or investigation been threatened, and
(b) there is no judgment, decree, injunction, rule or order of any Governmental
Authority, arbitrator or mediator outstanding against the Company or any of its
Subsidiaries, other than, in the cases of clauses (a) and (b), any such pending
or threatened actions, suits, arbitrations, mediations, proceedings, claims or
investigations or any such judgments, decrees, injunctions, rules or orders,
which, individually or in the aggregate, would not reasonably be expected to
have a Material Adverse Effect on the Company.

      3.6 Compliance with Laws.

            (a) Applicable Law. Except as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on the
Company, (1) the Company and each of its Subsidiaries has complied, and is now
in compliance, with all Applicable Law, (2) neither the Company nor any of its
Subsidiaries has received any written notification from any Governmental
Authority asserting that the Company or any of its Subsidiaries has failed to

against the Company or any of its Subsidiaries and no reasonable basis therefor
exists.

            (b) Permits. Except as would not, individually or in the aggregate,

                                       25


audited balance sheet included in the Company SEC Documents as being owned by
the Company or one of its Subsidiaries or acquired after the date thereof that
are material to the Company's business on a consolidated basis (except
properties sold or otherwise disposed of since the date thereof in the ordinary
course of business), free and clear of all Encumbrances, except (1) Permitted
Encumbrances, (2) such imperfections or irregularities of title, easements,
covenants, rights-of-way and other Encumbrances as do not materially impair the
continued use of the properties or assets subject thereto or affected thereby or
otherwise materially impair business operations at such properties, and (3)
mortgages deeds of trust, security interests or other encumbrances on title
related to indebtedness reflected on the consolidated financial statements of
the Company included in the Company SEC Documents, and (b) is the lessee of all

otherwise disposed of in the ordinary course of business consistent with past
practice) and is in possession of the properties purported to be leased
thereunder, and each such lease is valid without default thereunder by the
lessee or, to the Company's knowledge, the lessor.

      3.8 Taxes. The Company and each of its Subsidiaries (and any consolidated,
combined, unitary or aggregate group for tax purposes of which the Company or
any such Subsidiary is or has been a member), (a) has properly completed and
timely filed all material foreign, federal, state, local and municipal tax and

the Company Balance Sheet), and (d) has no Liability for material taxes in
excess of the amount so paid or accruals or reserves so established except for
taxes subsequent to the date of the Company Balance Sheet incurred in the
ordinary course of business. All such Returns are true, correct and complete in
all material respects. Neither the Company nor any of its Subsidiaries has
received any written notification from the Internal Revenue Service or any other
taxing authority regarding any material issues that (a) are currently pending
before the Internal Revenue Service or any other taxing agency or authority
(including any sales or use taxing authority) regarding the Company, or (b) have
been raised by the Internal Revenue Service or other taxing agency or authority
and not yet finally resolved. No material tax liens are currently in effect
against any of the assets of the Company or any of its Subsidiaries other than
liens that arise by operation of law for taxes not yet due and payable. There is
not in effect any waiver by the Company or any of its Subsidiaries of any
statute of limitations with respect to any material taxes. Neither the Company
nor any of its Subsidiaries has consented to extend to a date later than the
Agreement Date the period in which any material tax may be assessed or collected
by any taxing agency or authority. Neither the Company nor any of its
Subsidiaries is a party to or bound by any material tax sharing, tax indemnity,

any material liability or material potential liability to another party under
any such agreement. Neither the Company nor any of its Subsidiaries has ever
been a member of a consolidated, combined, unitary or aggregate group of which
the Company was not the ultimate parent corporation. Neither the Company nor any
of its Subsidiaries has constituted either a "distributing corporation" or a

                                       26


"controlled corporation" in a distribution of stock qualifying for tax-free
treatment under Section 355 of the Code (a) in the two years prior to the
Agreement Date or (b) in a distribution that could otherwise constitute part of
a "plan" or "series of related transactions" (within the meaning of Section
355(e) of the Code) in conjunction with the Merger. Neither the Company nor any
of its Subsidiaries has taken any action or knows of any fact, agreement, plan
or other circumstance that would reasonably be expected to prevent the Merger
from qualifying as a transaction described in Section 368(a) of the Code.

      3.9 Intellectual Property.

            (a) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on the Company, (1) the
Company and each of its Subsidiaries owns or has the valid right or license to
use, and, to the extent that it does any of the following, to develop, make,
have made, offer for sale, sell, import, copy, modify, create derivative works
of, distribute, license to third parties and/or dispose of (for purposes of this
Section 3.9, "USE") all Intellectual Property as currently Used in the conduct
of the business of the Company and its Subsidiaries (such Intellectual Property
being hereinafter collectively referred to as the "COMPANY IP RIGHTS"), and (2)
all such Company IP Rights are owned or licensed by the Company free of all
material liens and Encumbrances (other than Permitted Encumbrances). As used in
this Agreement, "COMPANY-OWNED IP RIGHTS" means Company IP Rights that are or
are purportedly owned or exclusively licensed to the Company or any of its
Subsidiaries.

            (b) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on the Company, neither
the Company's entry into this Agreement nor the performance of its obligations
contemplated hereby shall, in accordance with their terms (1) cause the
forfeiture or termination of, or give rise to a right of forfeiture or
termination of, any material Contract governing any Company IP Right, (2)
materially impair the right of the Company or the Surviving Corporation or any
Subsidiary of the Company to Use any Company IP Right or portion thereof as
currently Used in the conduct of the Company's business, or (3) cause any
royalties fees or other payments to become payable by the Company or any of its
Subsidiaries to any third person as a result of the Use of any Company IP Rights
by the Company or cause any existing obligations to pay such royalties, fees or
other payments to increase (other than due to increased sales of the Company's
products or services).

            (c) To the knowledge of the Company, and except as would not,
individually or in the aggregate, reasonably be excepted to have a Material
Adverse Effect on the Company, the Use of any Company IP Right as currently Used
in the conduct of its business does not infringe on or otherwise violate the
rights of any third party. As of the Agreement Date, there is no pending, or to
the knowledge of the Company, threatened, claim or litigation contesting the
validity, ownership or right of the Company or any of its Subsidiaries to
exercise any Company IP Right or which would reasonably be expected to result in
the abandonment, cancellation or unenforceability of such Company IP Rights, nor
to the knowledge of the Company as of the Agreement Date, is there any
legitimate basis for any such claim. None of the Company IP Rights is subject to
any proceeding or outstanding order, contract or stipulation materially
restricting the Company's use of the Company IP Rights in the aggregate. To the
knowledge of the Company, and except as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on the
Company, no third party is infringing or otherwise

                                       27


violating any Company IP Right (other than unlicensed end users of the Company's
commercially available software products).

            (d) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on the Company, (1) the
Company and each of its Subsidiaries has taken commercially reasonable steps to
protect, preserve and maintain the proprietary and confidential rights and trade
secrets in the Company IP Rights and (2) no current or former employee of, or
independent contractor who has worked with, the Company or any of its
Subsidiaries has any right or interest in any Company-Owned IP Rights.

            (e) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Company, all
registered Company-Owned IP Rights are to the knowledge of the Company valid,
enforceable and subsisting, and the Company or a Subsidiary of the Company is
the record owner thereof.

            (f) Schedule 3.9(f) of the Company Disclosure Letter lists, as of
the Agreement Date, all Contracts pursuant to which the Company or any of its
Subsidiaries grants a third party exclusive rights under any material Company IP
Rights.

            (g) To the knowledge of the Company, and except as would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the Company, no event has occurred, and no circumstance or
condition exists, that would reasonably be expected to result in the release by
the Company or any escrow agent to any third party of any Company Source Code.
"COMPANY SOURCE CODE" means, collectively, any human readable software source
code, or any material portion or aspect of the software source code which
comprise part of the Company-Owned IP Rights.

            (h) To the knowledge of the Company, Schedule 3.9(h) of the Company
Disclosure Letter lists Contracts with government entities, pursuant to which
material computer software programs or applications owned or co-owned by the
Company or any of its Subsidiaries were developed or co-developed and licensed
and/or assigned to the Company.

            (i) To the knowledge of the Company, the Company and its
Subsidiaries are in compliance with all their respective obligations pursuant to
any Public Software license agreements under which they license-in any material
Company IP Rights, except for such non-compliance that, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
the Company.

      3.10 Employment.

            (a) The Company, each of its Subsidiaries and each ERISA Affiliate
is in compliance with all Applicable Law and Contracts relating to each Company
Benefit Arrangement, each Company Foreign Plan, employment, employment
practices, immigration, wages, hours, and terms and conditions of employment,
including employee compensation matters, except where the failure to so comply
would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect on the Company.

                                       28


            (b) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on the Company, (1) no
union organizing effort with respect to employees of the Company or any of its
Subsidiaries in underway and (2) there is no labor strike, dispute, slowdown,
stoppage or lockout actually pending or, to the knowledge of the Company,
threatened against the Company or any of its Subsidiaries. There are no
controversies pending or, to the knowledge of the Company, threatened, between
the Company or any Subsidiary and any of their respective employees which have,
or would reasonably be expected to result in, an action, suit, proceeding,
claim, arbitration or investigation before any Governmental Authority, and which
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect on the Company.

            (c) To the knowledge of the Company, neither the Company, its
Subsidiaries, nor any ERISA Affiliate has at any time since the enactment of
ERISA, sponsored a "multiemployer plan" as defined in Section 3(37) of ERISA.
Neither the Company nor any Subsidiary or current or former ERISA Affiliate
currently maintains, sponsors, participates in or contributes to, nor has it
ever maintained, established, sponsored, participated in, or contributed to, any
pension plan (within the meaning of Section 3(2) of ERISA) that is subject to
Title IV of ERISA. To the knowledge of the Company, no "accumulated funding
deficiency" (as such term is defined in Section 302 of ERISA and Section 412 of
the Code) has occurred with respect to any Company Benefit Arrangement that is

ERISA Affiliate, the Company has made available to Parent (1) all employee
benefit plans within the meaning of Section 3(3) of ERISA currently contributed
to, sponsored by or maintained by the Company or any of its Subsidiaries, (2)
each outstanding loan from the Company, any of its Subsidiaries or an ERISA
Affiliate to an employee in excess of $250,000, (3) all stock option, stock

for at-will employment which do not provide for severance, acceleration or
post-termination benefits except as required by the law or applicable custom or
rule of the relevant jurisdiction outside of the United States) where the
obligations under any such agreement are in excess of $1,000,000 or if any such
agreement is a "material contract" (as such term is defined in Item 601(b)(10)
of Regulation S-K promulgated by the SEC), and (7) all change of control
agreements or severance agreements, written or otherwise, for the benefit of, or

                                       29

taken as a whole (collectively, the "COMPANY BENEFIT ARRANGEMENTS").

            (e) Neither the Company nor any of its Subsidiaries is a party to
any Contract with any director or officer of the Company (1) the benefits of
which are contingent, or the terms of which are materially altered as a result
of the execution of this Agreement, stockholder approval of this Agreement or
the transactions contemplated by this Agreement (whether alone or in connection
with any subsequent event(s)), or (2) providing any fixed term of employment. No

consultant of the Company or any of its Subsidiaries or ERISA Affiliate to which
the Company and/or any such Subsidiary is a party or by which the Company and/or
any such Subsidiary is bound that, considered individually or considered
collectively with any other such agreements, plans, arrangements or other
Contracts, will, or could reasonably be expected to, as a result of the

expected to be characterized as a "parachute payment" within the meaning of
Section 280G of the Code.

thereof) with respect to any of the capital stock of the Company, (c)
reclassification, combination, split or subdivision of any capital stock of the
Company, (d) redemption, purchase or other acquisition, directly or indirectly,
by the Company of any capital stock, other equity interests or other securities

excess of $10,000,000 in the aggregate for the Company and its Subsidiaries or

accuracy of the representations and warranties made by Parent and Merger Sub

consummate the transactions contemplated hereby and thereby, (b) have the effect
of invalidating or voiding this Agreement or the Certificate of Merger, or any

      Except as set forth in the disclosure letter of Parent addressed to the
Company, dated as of the Agreement Date and delivered to Parent concurrently
with the parties' execution of this Agreement (the "PARENT DISCLOSURE LETTER")
referencing a representation or warranty herein (it being understood that Parent
Disclosure Letter shall be arranged in sections and subsections corresponding to
the sections and subsections contained in this Agreement, and the disclosures in

                                       32


any section or subsection of Parent Disclosure Letter shall qualify all of the
applicable representations and warranties in the corresponding section or
subsection of this Article 4 and, in addition, in all other sections or
subsections in this Article 4 to the extent it is reasonably apparent from the
text of such disclosure that that such disclosure is applicable to such other
sections or subsections), Parent represents and warrants to the Company as
follows:

      4.1 Organization.

            (a) Standing and Power. Each of Parent and its Subsidiaries (i) is a
corporation or other entity duly organized, validly existing and in good
standing (with respect to jurisdictions which recognize such concept) under the
laws of the jurisdiction of its incorporation or organization, (ii) has the
requisite power and authority to own, lease and operate its properties and to
carry on its business as currently conducted, and (iii) is duly qualified or
licensed to do business, and is in good standing (with respect to jurisdictions
which recognize such concept), in each jurisdiction where the character of the
properties owned, leased or operated by it or the nature of its activities makes
such qualification or licensing necessary, in each case except as would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on Parent.

            (b) Charter Documents. Parent has made available to the Company or
filed with the SEC prior to the Agreement Date: (i) a complete and correct copy
of the Certificate of Incorporation (including any Certificates of Designation)
and Bylaws of Parent, each as amended to date, and (ii) a complete and correct
copy of the articles or certificate of incorporation and bylaws (or like
organizational documents), each as amended to date, of each of its Significant
Subsidiaries (collectively with the documents identified in the preceding clause
(i), the "PARENT CHARTER DOCUMENTS"), and each such instrument is in full force
and effect. Neither Parent nor any of such Subsidiaries is in violation of any
of its Parent Charter Documents, except in the case of such Significant
Subsidiaries as would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect on Parent.

            (c) Subsidiaries. Schedule 4.1(c) of the Parent Disclosure Letter
sets forth a list of each Subsidiary of Parent. All the outstanding shares of
capital stock of, or other equity or voting interests in, each Significant
Subsidiary of Parent (i) are owned directly or indirectly by Parent, free and

imposed by applicable securities laws), (ii) are not subject to any preemptive
right or right of first refusal created by Applicable Law, Parent Charter
Documents or any Contract to which such Significant Subsidiary is a party or by
which it is bound, and (iii) are duly authorized, validly issued, fully paid and
nonassessable. Other than the Subsidiaries of Parent, as of the Agreement Date,
neither Parent nor any of its Subsidiaries owns any capital stock of, or other
equity or voting interests of any nature in, or any interest convertible,
exchangeable or exercisable for, capital stock of, or other equity or voting
interests of any nature in, any other Person where the aggregate book value
reflected on Parent Balance Sheet (or the cost to Parent and its Subsidiaries
with respect to securities acquired after September 30, 2004) of all such
securities issued by any single Person exceeds $5,000,000. As of the Agreement
Date, there are no outstanding obligations of Parent or any of its Subsidiaries
under any Contract to which it is a party or by which it is otherwise bound to
make any loan to, or any equity or other investment (in the form of a capital
contribution or otherwise) in any other Person (other than Parent or such a
Subsidiary) in an amount in excess of $5,000,000 in respect of any single
Person.

            (f) No Conflict. The execution and delivery of this Agreement by
Parent and Merger Sub do not, and the consummation by Parent and Merger Sub of
the transactions contemplated hereby and compliance by Parent and Merger Sub

violation or breach of or default (with or without notice or lapse of time, or
both) under, or require any consent, waiver or approval under, (i) the Parent
Charter Documents, (ii) subject to compliance with the requirements set forth in
the preceding subsection (e), any Applicable Law applicable to Parent, any of

party or by which Parent or any of its Subsidiaries is bound, other than, in the
cases of clauses (ii) and (iii), any such conflicts, violations, breaches or
defaults, or failure to obtain consents, waivers or approvals, which,
individually or in the aggregate, would not reasonably be expected to materially

            (b) Financial Statements. Each of the consolidated financial
statements (including, in each case, any related notes thereto) contained in the
Parent SEC Documents (the

                                       37


"PARENT FINANCIAL STATEMENTS"), including each Parent SEC Document filed after
the Agreement Date until the Closing, (i) complied, as of their respective dates
of filing with the SEC, as to form in all material respects with the published
rules and regulations of the SEC with respect thereto, (ii) was prepared in
accordance with GAAP (except in the case of unaudited interim financial

a consistent basis throughout the periods involved (except as may be indicated
in the notes thereto), and (iii) fairly presented in all material respects the
consolidated financial position of Parent and its Subsidiaries as at the
respective dates thereof and the consolidated results of Parent's and its
Subsidiaries' operations and cash flows for the periods indicated (except that
the unaudited interim financial statements were subject to normal and recurring
year-end and quarter-end adjustments which were not material). Except as
reflected in the balance sheet of Parent dated October 1, 2004 included in the
Form 10-Q filed by Parent with the SEC on November 8, 2004 (the "PARENT BALANCE
SHEET") (or described in the notes thereto), neither Parent nor any of its
Subsidiaries has any Liabilities of any nature that would be required to be
disclosed on a consolidated balance sheet of Parent and its Subsidiaries
prepared in accordance with GAAP consistently applied, except (i) Liabilities
incurred since October 1, 2004 in the ordinary course of business consistent
with past practice, (ii) Liabilities under a Parent Material Contract (as
defined in Section 4.12 below) set forth on Schedule 4.4(b) of the Parent

Subsidiaries subsequent to the Agreement Date not in violation of Section 5.2(b)
below, (iii) Liabilities reserved against in the Parent Balance Sheet (but only
to the extent of such reserve), (iv) Liabilities incurred in connection with
this Agreement or the transactions contemplated hereby, and (v) Liabilities
which, individually or in the aggregate, would not reasonably be expected to

            (c) Sarbanes Act. Each of the principal executive officer of Parent
and the principal financial officer of Parent (or each former principal
executive officer of Parent and each former principal financial officer of
Parent, as applicable) has made all certifications required by Rule 13a-14 or
Rule 15d-14 under the Exchange Act or Sections 302 and 906 of the Sarbanes Act
and the rules and regulations of the SEC promulgated thereunder with respect to
Parent SEC Documents. For purposes of the preceding sentence, "principal
executive officer" and "principal financial officer" shall have the meanings
given to such terms in the Sarbanes Act.

            (d) Amendments. Parent has heretofore made available to the Company
a complete and correct copy of any amendments or modifications effected prior to
the Agreement Date, which have not yet been filed with the SEC but which are
required to be filed, to agreements, documents or other instruments which
previously had been filed by Parent with the SEC pursuant to the Securities Act
or the Exchange Act.

            (e) Registration Statement. The information supplied by Parent for
inclusion in the Registration Statement shall not at the time the Registration
Statement is filed with the SEC and at the time it becomes effective under the
Securities Act contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein not misleading. The information supplied by Parent for
inclusion or incorporation by reference in the Proxy Statement/Prospectus shall
not, on the date the Proxy Statement/Prospectus is mailed to Company
Stockholders or Parent Stockholders, at the time of the Company Stockholders'
Meeting, at the time of the meeting of Parent

                                       38


Stockholders' Meeting to consider the Parent Stockholder Approval or as of the
Effective Time, contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they are made,
not false or misleading, or omit to state any material fact necessary to correct
any statement in any earlier communication with respect to the solicitation of
proxies for the Company Stockholders' Meeting or the Parent Stockholders'
Meeting which has become false or misleading. The Registration Statement and the
Proxy Statement/Prospectus will comply as to form in all material respects with
the provisions of the Exchange Act and the rules and regulations thereunder. If
at any time prior to the Effective Time any event relating to Parent or any of
its Affiliates, officers or directors should be discovered by Parent which is
required to be set forth in an amendment to the Registration Statement or a
supplement to the Proxy Statement/Prospectus, Parent shall promptly inform the
Company. Notwithstanding the foregoing, Parent makes no representation or
warranty with respect to any statements made or incorporated by reference
therein based on information supplied by the Company that is contained
(including by incorporation by reference) in any of the foregoing documents.

      4.5 Litigation. Except as and to the extent disclosed in the Parent SEC
Documents filed prior to the Agreement Date (including the notes to the
financial statements included therein), (a) there is no action, suit,
arbitration, mediation, proceeding, claim or investigation pending against
Parent or any of its Subsidiaries before any Governmental Authority, arbitrator
or mediator, nor, to the knowledge of the Company, has any such action, suit,
arbitration, mediation, proceeding, claim or investigation been threatened, and
(b) there is no judgment, decree, injunction, rule or order of any Governmental
Authority, arbitrator or mediator outstanding against Parent or any of its
Subsidiaries, other than, in the cases of clauses (a) and (b), any such pending
or threatened actions, suits, arbitrations, mediations, proceedings, claims or
investigations or any such judgments, decrees, injunctions, rules or orders,
which, individually or in the aggregate, would not reasonably be expected to
have a Material Adverse Effect on Parent.

      4.6 Compliance with Laws.

            (a) Applicable Law. Except as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on Parent,
(1) Parent and each of its Subsidiaries has complied, and is now in compliance,
with all Applicable Law, (2) neither Parent nor any of its Subsidiaries has
received any written notification from any Governmental Authority asserting that
Parent or any of its Subsidiaries has failed to comply, or is not in compliance,
with Applicable Law and to Parent's knowledge, no investigation or review of
Parent or any of its Subsidiaries by any Governmental Authority is pending, and
(3) to Parent's knowledge, no such notification, investigation or review has
been threatened in writing against Parent or any of its Subsidiaries and no
reasonable basis therefor exists.

            (b) Permits. Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent, (1) Parent
and its Subsidiaries hold all Governmental Permits and all such Governmental
Permits are valid and in full force and effect, (2) neither Parent nor any of
its Subsidiaries has received any written notification from any Governmental
Authority asserting that Parent or any of its Subsidiaries has failed to comply
with or is not in compliance with any such Governmental Permit or regarding any
actual or possible revocation, withdrawal, suspension, cancellation, termination
or modification of any such

                                       39


Governmental Permit, and (3) to Parent's knowledge, no such notification has
been threatened in writing against Parent or any of its Subsidiaries and no
reasonable basis therefor exists.

      4.7 Properties. Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent, Parent or
one of its Subsidiaries (a) has good and valid title to all the properties and
assets reflected in the latest audited balance sheet included in the Parent SEC
Documents as being owned by Parent or one of its Subsidiaries or acquired after
the date thereof that are material to Parent's business on a consolidated basis
(except properties sold or otherwise disposed of since the date thereof in the
ordinary course of business), free and clear of all Encumbrances, except (1)
Permitted Encumbrances, (2) such imperfections or irregularities of title,
easements, covenants, rights-of-way and other Encumbrances as do not materially
impair the continued use of the properties or assets subject thereto or affected
thereby or otherwise materially impair business operations at such properties,
and (3) mortgages, deeds of trust, security interests or other encumbrances on
title related to indebtedness reflected on the consolidated financial statements
of Parent included in the Parent SEC Documents, and (b) is the lessee of all
leasehold estates reflected in the latest audited financial statements included
in the Parent SEC Documents or acquired after the date thereof that are material
to its business on a consolidated basis (except for leases that have expired by
their terms since the date thereof or been assigned, terminated or otherwise
disposed of in the ordinary course of business consistent with past practice)
and is in possession of the properties purported to be leased thereunder, and
each such lease is valid without default thereunder by the lessee or, to
Parent's knowledge, the lessor.

      4.8 Taxes. Parent and each of its Subsidiaries (and any consolidated,
combined, unitary or aggregate group for tax purposes of which Parent or any
such Subsidiary is or has been a member), (a) has properly completed and timely
filed all material Returns required to be filed by it, (b) has timely paid all
material taxes required to be paid by it for which payment was due, (c) has
established an adequate accrual or reserve in accordance with GAAP applied on a
consistent basis for the payment of all material taxes payable in respect of the
periods or portions thereof prior to the date of Parent Balance Sheet (which
accrual or reserve as of such date is fully reflected on Parent Balance Sheet),
and (d) has no Liability for material taxes in excess of the amount so paid or
accruals or reserves so established except for taxes subsequent to the date of
Parent Balance Sheet incurred in the ordinary course of business. All such
Returns are true, correct and complete in all material respects. Neither Parent
nor any of its Subsidiaries has received any written notification from the
Internal Revenue Service or any other taxing authority regarding any material
issues that (a) are currently pending before the Internal Revenue Service or any
other taxing agency or authority (including any sales or use taxing authority)
regarding Parent, or (b) have been raised by the Internal Revenue Service or
other taxing agency or authority and not yet finally resolved. No material tax
liens are currently in effect against any of the assets of Parent or any of its
Subsidiaries other than liens that arise by operation of law for taxes not yet
due and payable. There is not in effect any waiver by Parent or any of its
Subsidiaries of any statute of limitations with respect to any material taxes.
Neither Parent nor any of its Subsidiaries has consented to extend to a date
later than the Agreement Date the period in which any material tax may be
assessed or collected by any taxing agency or authority. Neither Parent nor any
of its Subsidiaries is a party to or bound by any material tax sharing, tax
indemnity, or tax allocation agreement nor does Parent or any of its
Subsidiaries have any material liability or material potential liability to
another party under any such agreement.

                                       40


Neither Parent nor any of its Subsidiaries has ever been a member of a
consolidated, combined, unitary or aggregate group of which Parent was not the
ultimate parent corporation. Neither Parent nor any of its Subsidiaries has
constituted either a "distributing corporation" or a "controlled corporation" in
a distribution of stock qualifying for tax-free treatment under Section 355 of
the Code (a) in the two years prior to the Agreement Date or (b) in a
distribution that could otherwise constitute part of a "plan" or "series of
related transactions" (within the meaning of Section 355(e) of the Code) in
conjunction with the Merger. Neither Parent nor any of its Subsidiaries has
taken any action or knows of any fact, agreement, plan or other circumstance
that would reasonably be expected to prevent the Merger from qualifying as a
transaction described in Section 368(a) of the Code.

      4.9 Intellectual Property.

            (a) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent, (1) Parent
and each of its Subsidiaries owns or has the valid right or license to use, and,
to the extent that it does any of the following, to develop, make, have made,
offer for sale, sell, import, copy, modify, create derivative works of,
distribute, license to third parties and/or dispose of (for purposes of this
Section 4.9, "USE") all Intellectual Property as currently Used in the conduct
of the business of the Parent and its Subsidiaries (such Intellectual Property
being hereinafter collectively referred to as the "PARENT IP RIGHTS"), and (ii)
all such Parent IP Rights are owned or licensed by the Parent free of all
material liens and Encumbrances (other than Permitted Encumbrances). As used in
this Agreement, "PARENT-OWNED IP RIGHTS" means Parent IP Rights that are or are
purportedly owned or exclusively licensed to Parent or any of its Subsidiaries.

            (b) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent, neither
Parent's entry into this Agreement nor the performance of its obligations
contemplated hereby shall, in accordance with their terms (1) cause the
forfeiture or termination of, or give rise to a right of forfeiture or
termination of, any material Contract governing any Parent IP Right, (2)
materially impair the right of the Parent or any Subsidiary of the Parent to Use
any Parent IP Right or portion thereof as currently Used in the conduct of the
Parent's business, or (3) cause any royalties fees or other payments to become
payable by the Parent or any of its Subsidiaries to any third person as a result
of the Use of any Parent IP Rights by the Parent or cause any existing
obligations to pay such royalties, fees or other payments to increase (other
than due to increased sales of the Parent's products or services).

            (c) To the knowledge of the Parent, and except as would not,
individually or in the aggregate, reasonably be excepted to have a Material
Adverse Effect on the Parent, the Use of any Parent IP Right as currently Used
in the conduct of its business does not infringe on or otherwise violate the
rights of any third party. As of the Agreement Date, there is no pending, or to
the knowledge of the Parent, threatened, claim or litigation contesting the
validity, ownership or right of the Parent or any of its Subsidiaries to
exercise any Parent IP Right or which would reasonably be expected to result in
the abandonment, cancellation or unenforceability of such Parent IP Rights, nor
to the knowledge of the Parent as of the Agreement Date, is there any legitimate
basis for any such claim. None of the Parent IP Rights is subject to any
proceeding or outstanding order, contract or stipulation materially restricting
the Parent's use of the Parent IP Rights in the aggregate. To the knowledge of
the Parent, and except

                                       41


as would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect on the Parent, no third party is infringing or otherwise
violating any Parent IP Right (other than unlicensed end users of the Parent's
commercially available software products).

            (d) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent, (1) the
Parent and each of its Subsidiaries has taken commercially reasonable steps to
protect, preserve and maintain the proprietary and confidential rights and trade
secrets in the Parent IP Rights and (2) no current or former employee of, or
independent contractor who has worked with, the Parent or any of its
Subsidiaries has any right or interest in any Parent-Owned IP Rights.

            (e) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent, all
registered Parent-Owned IP Rights are to the knowledge of Parent valid,
enforceable and subsisting, and Parent or a Subsidiary of Parent is the record
owner thereof.

            (f) Schedule 4.9(f) of the Parent Disclosure Letter lists, as of the
Agreement Date, all Contracts pursuant to which Parent or any of its
Subsidiaries grants a third party exclusive rights under any material Parent IP
Rights.

            (g) To the knowledge of Parent, and except as would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on Parent, no event has occurred, and no circumstance or
condition exists, that would reasonably be expected to result in the release by
Parent or any escrow agent to any third party of any Parent Source Code. "PARENT
SOURCE CODE" means, collectively, any human readable software source code, or
any material portion or aspect of the software source code which comprise part
of the Parent-Owned IP Rights.

            (h) To the knowledge of Parent, Schedule 4.9(h) of the Parent
Disclosure Letter lists Contracts with government entities, pursuant to which
material computer software programs or applications owned or co-owned by Parent
or any of its Subsidiaries were developed or co-developed and licensed and/or
assigned to Parent.

            (i) To the knowledge of Parent, Parent and its Subsidiaries are in
compliance with all their respective obligations pursuant to any Public Software
license agreements under which they license-in any material Parent IP Rights,
except for such non-compliance that, individually or in the aggregate, would not
reasonably be expected to have a Material Adverse Effect on Parent.

      4.10 Employment.

            (a) Parent, each of its Subsidiaries and each ERISA Affiliate is in
compliance with all Applicable Law and Contracts relating to each Parent Benefit
Arrangement, each Parent Foreign Plan, employment, employment practices,
immigration, wages, hours, and terms and conditions of employment, including
employee compensation matters, except where the failure to so comply would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on Parent.

                                       42


            (b) Except as would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent, (1) no union
organizing effort with respect to employees of Parent or any of its Subsidiaries
in underway and (2) there is no labor strike, dispute, slowdown, stoppage or
lockout actually pending or, to the knowledge of Parent, threatened against
Parent or any of its Subsidiaries. There are no controversies pending or, to the
knowledge of Parent, threatened, between Parent or any Subsidiary and any of
their respective employees which have, or would reasonably be expected to result
in, an action, suit, proceeding, claim, arbitration or investigation before any
Governmental Authority, and which individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect on Parent.

            (c) To the knowledge of Parent, neither Parent, its Subsidiaries,
nor any ERISA Affiliate has at any time since the enactment of ERISA, sponsored
a "multiemployer plan" as defined in Section 3(37) of ERISA. Neither Parent nor
any Subsidiary or current or former ERISA Affiliate currently maintains,
sponsors, participates in or contributes to, nor has it ever maintained,
established, sponsored, participated in, or contributed to, any pension plan
(within the meaning of Section 3(2) of ERISA) that is subject to Title IV of
ERISA. To the knowledge of Parent, no "accumulated funding deficiency" (as such
term is defined in Section 302 of ERISA and Section 412 of the Code) has
occurred with respect to any Parent Benefit Arrangement that is not subject to
Title IV of ERISA.

            (d) With respect to Parent, any of its Subsidiaries and any ERISA
Affiliate, Parent has made available to the Company (1) all employee benefit
plans within the meaning of Section 3(3) of ERISA currently contributed to,
sponsored by or maintained by Parent or any of its Subsidiaries, (2) each
outstanding loan from Parent, any of its Subsidiaries or an ERISA Affiliate to
an employee in excess of $250,000, (3) all stock option, stock purchase, phantom

Parent or any of its Subsidiaries, (4) all bonus, pension, profit sharing,
savings, retirement, deferred compensation or incentive plans, programs or
arrangements (other than Parent Foreign Plans) currently contributed to,
sponsored by or maintained by Parent or any of its Subsidiaries, (5) other
fringe or employee benefit plans, programs or arrangements that apply to senior
management and that do not generally apply to all employees that are currently
contributed to, sponsored by or maintained by Parent or any of its Subsidiaries,
and (6) all employment or service agreements with a current service provider
(except for offer letters providing for at-will employment which do not provide
for severance, acceleration or post-termination benefits except as required by
the law or applicable custom or rule of the relevant jurisdiction outside of the
United States) where the obligations under any such agreement are in excess of
$1,000,000 or if any such agreement is a "material contract" (as such term is
defined in Item 601(b)(10) of Regulation S-K promulgated by the SEC), and (7)
all change of control agreements or severance agreements, written or otherwise,
for the benefit of, or relating to, (x) any current director or officer of
Parent or (y) any current employee or consultant (where the obligations of
Parent or any of its Subsidiaries to such employee or consultant are greater
than $500,000, of Parent or any of its Subsidiaries, in each case in the
foregoing clauses (1)-(7) to the extent such plans, loans, programs,
arrangements, agreements or other items are material to the

                                       43


business of Parent and its Subsidiaries taken as a whole (collectively, the
"PARENT BENEFIT ARRANGEMENTS").

            (e) Neither Parent nor any of its Subsidiaries is a party to any
Contract with any director or officer of Parent (1) the benefits of which are
contingent, or the terms of which are materially altered as a result of the
execution of this Agreement, stockholder approval of this Agreement or the
transactions contemplated by this Agreement (whether alone or in connection with
any subsequent event(s)), or (2) providing any fixed term of employment. No
Parent Benefit Arrangement will provide benefits that shall be increased, or the
vesting of benefits of which shall be accelerated or the value of any of the
benefits of which shall be calculated as a result of the execution of this
Agreement, stockholder approval of this Agreement, or the transactions
contemplated by this Agreement (whether alone or in connection with any
subsequent event(s)).

      4.11 Absence of Certain Changes. Since October 1, 2004, Parent and each of
its Subsidiaries has operated its business in all material respects in the
ordinary course consistent with its past practices, and since such date there

(a) any Effect or Effects that, individually or in the aggregate, have had or

relationship with any employee), or (e) through the Agreement Date any
incurrence of any indebtedness for borrowed money in excess of $10,000,000 in
the aggregate for Parent and its Subsidiaries or issuance of any debt securities
or assumption, guarantee or endorsement of the obligations of any Person (other
than a wholly-owned Subsidiary of Parent) for borrowed money (except for
indebtedness for borrowed money under or guarantees with respect to indebtedness
under any existing credit facility or indebtedness of any wholly-owned
Subsidiary of Parent to any other wholly-owned Subsidiary of Parent or
indebtedness of Parent to any wholly-owned Subsidiary of Parent).

      4.12 Material Contracts.

            (a) Listing. Except for this Agreement, neither Parent nor any of
its Subsidiaries is a party to or bound by any of the following as of the
Agreement Date (each, a "PARENT MATERIAL CONTRACT"):

                                       44

competing in any line of business, market or geographic area, (ii) contains most

in each case in a manner which is material to the business of Parent and its
Subsidiaries taken as a whole;

                  (4) any Contract that would reasonably be expected to prevent,
materially delay or materially impede the consummation of any of the
transactions contemplated by this Agreement; or

                  (5) any Contract the termination of which would reasonably be
expected to have a Material Adverse Effect on Parent.

            (b) No Default. Neither Parent nor any of its Subsidiaries, nor, to
Parent's knowledge, any counterparty to any Parent Material Contract, has
violated any provision of, or committed or failed to perform any act which (with
or without notice, lapse of time or both), would constitute a default under, or
give any counterparty the right to exercise any remedy (including the right to a
rebate, refund, credit, change in performance schedule, cancellation,
termination or modification) pursuant to, the provisions of any Parent Material
Contract, except in each case for those violations and defaults which,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on Parent.

      4.13 Environmental Matters. Except as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on Parent,
(a) the operations of Parent and its Subsidiaries are, and at all times have
been, in compliance with all applicable Environmental Laws, including possession

or released any Hazardous Materials in violation of, or in a manner that would
reasonably be expected to give rise to liability to Parent or its Subsidiaries

of the proxy statement for the 2004 Annual Meeting of Stockholders of Parent, no
event has occurred as of the Agreement Date that would be required to be

of Regulation S-K promulgated by the SEC.

                                       45


      4.15 State Takeover Statutes. Parent has, or will have prior to the

and warranties made by the Company herein, no "business combination,"
"moratorium," "fair price," "control share acquisition" or other state
antitakeover statute or regulation, nor any takeover-related provision in the
Parent Charter Documents, would (a) prohibit or restrict Parent's and Merger
Sub's ability to perform their respective obligations under this Agreement, any
related agreement or the Certificate of Merger or their ability to consummate
the transactions contemplated hereby and thereby, (b) have the effect of
invalidating or voiding this Agreement or the Certificate of Merger, or any
provision hereof or thereof, or (c) subject the Company to any impediment or
condition in connection with the exercise of any of its rights under this
Agreement or the Certificate of Merger.

                                       51


            (a) Alternative Transaction. Neither the Company nor Parent shall,
nor shall the Company or Parent permit any of its Subsidiaries to, nor authorize
or permit any of its or its Subsidiaries', officers, directors or employees or
any investment banker, financial advisor, attorney, accountant or other
representative retained by it or any of its Subsidiaries to, directly, or
indirectly, (i) solicit, initiate or encourage, or take any other action to
knowingly facilitate any inquiries with respect to, or the making, submission or
announcement of, any Alternative Transaction Proposal, (ii) participate in any
discussions or negotiations regarding, furnish to any Person any information
with respect to, or knowingly facilitate any effort or attempt to make or
implement any Alternative Transaction Proposal (except to disclose the existence
of this Agreement and the terms hereof or as specifically permitted by Section
5.2(c)), (iii) approve, endorse or recommend any Alternative Transaction (except
to the extent specifically permitted by Section 5.2(d)), or (iv) enter into any
letter of intent or similar document or any contract, agreement or commitment
(whether binding or not) contemplating or otherwise relating to any Alternative
Transaction Proposal (except any confidentiality agreement contemplated by
Section 5.2(c)(1)). Each of the Company and Parent and each of their respective
Subsidiaries will immediately cease, and will cause its officers, directors and
employees and instruct any investment banker, financial adviser, attorney,
accountant or other representative retained by it to cease, any and all existing
activities, discussions or negotiations with any third parties conducted
heretofore with respect to any Alternative Transaction Proposal, and will use
its reasonable best efforts to enforce, and will not waive any provisions of,
any confidentiality or standstill agreement (or any similar agreement) to which
such party of any of its Subsidiaries is a party relating to any such
Alternative Transaction Proposal.

            (b) Notification. As promptly as practicable (and in any event
within 24 hours) after receipt of any Alternative Transaction Proposal or any
request for nonpublic information or any inquiry relating in any way to any
Alternative Transaction Proposal, the Company or Parent, as the case may be,
shall provide the other party with oral and written notice of the material terms
and conditions of such Alternative Transaction Proposal, request or inquiry, and
the identity of the Person or group making any such Alternative Transaction
Proposal, request or inquiry and a copy of all written materials provided to it
in connection with such Alternative Transaction Proposal, request or inquiry. In
addition, the Company or Parent, as the case may be, shall provide the other
party as promptly as possible with all information as is reasonably necessary to
keep the other party informed in all material respects of all oral or written
communications regarding, and the status and material terms of, any such
Alternative Transaction Proposal, request or inquiry, and, without limitation of
the other provisions of this Section 5.2, shall promptly provide to the other
party a copy of all written materials (including written materials provided by
email or otherwise in electronic format) subsequently provided by or to it in
connection with such Alternative Transaction Proposal, request or inquiry. The
Company or Parent, as the case may be, shall provide the other party with 48
hours prior notice (or such lesser prior notice as is provided to the members of
its Board of Directors) of any meeting of its Board of Directors at which its
Board of Directors is reasonably expected to consider any Alternative
Transaction Proposal or Alternative Transaction.

            (c) Superior Proposal. Notwithstanding anything to the contrary
contained in Section 5.2(a), in the event that the Company or Parent, as the
case may be, receives an unsolicited, bona fide written Alternative Transaction
Proposal which is determined to be, or to be reasonably likely to result in, a
Superior Proposal, such party or its Board of Directors may

                                       52


then take the following actions (but only (i) if and to the extent that (x) its
Board of Directors concludes in good faith, after consultation with its outside
legal counsel, that the failure to do so would be inconsistent with its
fiduciary duties under Applicable Law, and (y) the Company or Parent, as the
case may be, has given the other party at least two business days prior written
notice of its intention to take any of the following actions and of the identity
of the Person or group making such Alternative Transaction Proposal and the
material terms and conditions of such Alternative Transaction Proposal and (ii)
if it shall not have breached in any material respect any of the provisions of
this Section 5.2):

                  (1) Furnish nonpublic information to the Person or group
making such Alternative Transaction Proposal, provided that (A) prior to
furnishing any such nonpublic information, it receives from such Person or group
an executed confidentiality agreement containing confidentiality terms at least
as restrictive as the terms contained in the Confidentiality Agreement, dated as
of September 30, 2004, between the Company and Parent (the "CONFIDENTIALITY
AGREEMENT") and (B) contemporaneously with furnishing any such nonpublic
information to such Person or group, it furnishes such nonpublic information to
the other party hereto (to the extent such nonpublic information has not been
previously so furnished to such party); and

                  (2) Engage in discussions or negotiations with such Person or
group with respect to such Alternative Transaction Proposal.

            (d) Changes of Recommendation. Solely in response to the receipt of
an unsolicited, bona fide written Alternative Transaction Proposal which its
Board of Directors concludes in good faith, after consultation with its outside
legal counsel and financial advisors, is a Superior Proposal, the Board of
Directors of the Company or Parent, as the case may be, may make a Change of
Recommendation, if all of the following conditions in clauses (1) through (5)
are met:

                  (1) the Superior Proposal has been made and has not been
withdrawn and continues to be a Superior Proposal;

                  (2) the stockholder vote at the Company Stockholders' Meeting
or Parent Stockholders' Meeting, as the case may be, has not occurred, and the
polls on the matters to be voted on at the Company Stockholders' Meeting or
Parent Stockholders' Meeting, as the case may be, have not been closed;

                  (3) the Company or Parent, as the case may be, has (A)
provided to the other party hereto four business days' prior written notice
which shall state expressly (i) that it has received a Superior Proposal, (ii)
the material terms and conditions of the Superior Proposal and the identity of
the Person or group of Persons making the Superior Proposal, and (iii) that it
intends to effect a Change of Recommendation and the manner in which it intends
to do so, and (B) during the aforementioned period, if requested by the other
party hereto, engaged in good faith negotiations to amend this Agreement in such
a manner that the Alternative Transaction Proposal which was determined to be a
Superior Proposal no longer is a Superior Proposal;

                  (4) the Board of Directors of the Company or Parent, as the
case may be, has determined in good faith, after consultation with its outside
legal counsel, that, in light of

                                       53


such Superior Proposal, the failure of the Board of Directors to effect a Change
of Recommendation would be inconsistent with its fiduciary duties under
Applicable Law; and

                  (5) the Company or Parent, as the case may be, shall have
complied with Section 5.2(c) and shall not have breached in any material respect
any of the other provisions set forth in this Section 5.2.

            (e) Tender Offer Rules. Nothing contained in this Agreement shall
prohibit the Company or Parent or their respective Boards of Directors from
taking and disclosing to their stockholders a position contemplated by Rules
14d-9 and 14e-2(a) promulgated under the Exchange Act.

      5.3 Preparation of SEC Documents; Stockholders' Meetings.


            (a) Registration Statement and Prospectus. As soon as reasonably
practicable following the Agreement Date, Parent and the Company shall prepare
and file with the SEC the Proxy Statement/Prospectus, and Parent shall prepare
and file with the SEC the Registration Statement, in which the Proxy
Statement/Prospectus will be included. Each of Parent and the Company shall use
reasonable best efforts to have the Registration Statement declared effective
under the Securities Act as promptly as practicable after such filing and to
keep the Form S-4 effective as long as is necessary to consummate the Merger and
the other transactions contemplated hereby. Parent will use reasonable best
efforts to cause the Proxy Statement/Prospectus to be mailed to Parent
Stockholders, and the Company will use reasonable best efforts to cause the
Proxy Statement/Prospectus to be mailed to Company Stockholders, in each case as
promptly as practicable after the Registration Statement is declared effective
under the Securities Act. Parent shall also take any action (other than
qualifying to do business in any jurisdiction in which it is not now so
qualified or filing a general consent to service of process) required to be
taken under any applicable state securities laws in connection with the issuance
and reservation of shares of Parent Common Stock in the Merger and the
conversion of Company Options into Parent Options, and the Company shall furnish
all information concerning the Company and the holders of Company Common Stock
as may be reasonably requested in connection with any such action. No filing of,
or amendment or supplement to, the Registration Statement or the Proxy
Statement/Prospectus will be made by Parent without the Company's prior consent
(which shall not be unreasonably withheld) and without providing the Company the
opportunity to review and comment thereon. Parent will advise the Company,
promptly after it receives oral or written notice thereof, of the time when the
Registration Statement has become effective or any supplement or amendment has
been filed, the issuance of any stop order, the suspension of the qualification
of the Parent Common Stock issuable in connection with the Merger for offering
or sale in any jurisdiction, or any oral or written request by the SEC for
amendment of the Proxy Statement/Prospectus or the Registration Statement or
comments thereon and responses thereto or requests by the SEC for additional
information and will promptly provide the Company with copies of any written
communication from the SEC or any state securities commission. If at any time
prior to the Effective Time any information (including any Change of
Recommendation) relating to Parent or the Company, or any of their respective
Affiliates, officers or directors, should be discovered by Parent or the Company
which should be set forth in an amendment or supplement to any of the
Registration Statement or the Proxy Statement/Prospectus, so that any of such
documents would not include any misstatement of a material fact or omit to state
any material fact necessary to make the statements therein not

                                       54


misleading, the party which discovers such information shall promptly notify the
other parties hereto and an appropriate amendment or supplement describing such
information shall be promptly filed with the SEC and, to the extent required by
law, disseminated to the stockholders of Parent and the Company.

            (b) Stockholders' Meetings. Each of the Company and Parent shall, as
promptly as practicable after the Registration Statement is declared effective
under the Securities Act, take all action necessary in accordance with
Applicable Law and the Company Charter Documents, in the case of the Company,
and the Parent Charter Documents, in the case of Parent, to duly give notice of,
convene and hold the Company Stockholders' Meeting, in the case of the Company,
and the Parent Stockholders' Meeting, in the case of Parent. Subject to Section
5.2(d), each of the Company and Parent will use reasonable best efforts to
solicit from its stockholders proxies in favor of, in the case of the Company,
the adoption of this Agreement, and in the case of Parent, the approval of the
Parent Stock Issuance and Parent Charter Amendments, and will take all other
action necessary or advisable to secure the vote or consent of its stockholders
required by the rules of the Nasdaq Stock Market or Applicable Law to obtain
such approvals. Notwithstanding anything to the contrary contained in this
Agreement, the Company or Parent may adjourn or postpone the Company
Stockholders' Meeting or Parent Stockholders' Meeting, as the case may be, to
the extent necessary to ensure that any necessary supplement or amendment to the
Proxy Statement/Prospectus is provided to its stockholders in advance of a vote
on, in the case of the Company, the adoption of this Agreement, and in the case
of Parent, the approval of the Parent Stock Issuance and Parent Charter
Amendments, or, if, as of the time for which the Company Stockholders' Meeting
or Parent Stockholders' Meeting, as the case may be, is originally scheduled,
there are insufficient shares of Company Common Stock or Parent Common Stock, as
the case may be, represented (either in person or by proxy) to constitute a
quorum necessary to conduct the business of such meeting. Each of the Company
and Parent shall ensure that the Company Stockholders' Meeting and the Parent
Stockholders' Meeting, respectively, is called, noticed, convened, held and
conducted, and that all proxies solicited in connection with the Company
Stockholders' Meeting or Parent Stockholders' Meeting, as the case may be, are
solicited in compliance with Applicable Law, the rules of the Nasdaq Stock
Market and, in the case of the Company, the Company Charter Documents, and, in
the case of Parent, the Parent Charter Documents. Without the prior written
consent of Parent, adoption of this Agreement is the only matter (other than
procedural matters) which the Company shall propose to be acted on by the
Company Stockholders at the Company Stockholders' Meeting. Without the prior
written consent of the Company, approval of the Parent Stock Issuance, the
Parent Charter Amendments and any proposals set forth in Schedule 5.3(b) of the
Parent Disclosure Letter are the only matters (other than procedural matters)
which Parent shall propose to be acted on by Parent Stockholders at the Parent
Stockholders' Meeting. Notwithstanding any Change of Recommendation by the Board
of Directors of the Company or Parent, (i) adoption of this Agreement shall be
submitted to the Company Stockholders at the Company Stockholders' Meeting and
(ii) approval of the Parent Stock Issuance and Parent Charter Amendments shall
be submitted to the Parent Stockholders at the Parent Stockholders' Meeting, and
nothing contained herein shall be deemed to relieve the Company or Parent of
such obligations.

            (c) Time of Meetings. Each of the Company and Parent will use
reasonable best efforts to hold the Company Stockholders' Meeting and Parent
Stockholders' Meeting,

                                       55


respectively, on the same date as the other party and as soon as reasonably
practicable after the date of this Agreement.

            (d) Board Recommendations. Except to the extent expressly permitted
by Section 5.2(d): (i) the Board of Directors of each of the Company and Parent
shall recommend that its stockholders vote in favor of, in the case of the
Company, the adoption of this Agreement at the Company Stockholders' Meeting,
and, in the case of Parent, the approval of the Parent Stock Issuance and Parent
Charter Amendments at the Parent Stockholders' Meeting, (ii) the Proxy
Statement/Prospectus shall include a statement to the effect that the Board of
Directors of (A) the Company has recommended that the Company Stockholders vote
in favor of adoption of this Agreement at the Company Stockholders' Meeting and
(B) Parent has recommended that Parent Stockholders vote in favor of approval of
the Parent Stock Issuance and Parent Charter Amendments and (iii) neither the
Board of Directors of the Company or Parent nor any committee thereof shall
withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in
a manner adverse to the other party, the recommendation of its respective Board
of Directors that the respective stockholders of the Company or Parent vote in
favor of, in the case of the Company, the adoption of this Agreement, and, in
the case of Parent, the approval of the Parent Stock Issuance and Parent Charter
Amendments.

      5.4 Accountant's Letters. Each of the Company and Parent shall use
commercially reasonable efforts to cause to be delivered to the other party two
letters from their respective independent accountants, one dated approximately
as of the date the Registration Statement is declared effective and one dated
approximately as of the Closing Date, each addressed to the other party, in form
and substance reasonably satisfactory to the other party and customary in scope
and substance for comfort letters delivered by independent public accountants in
connection with registration statements similar to the Registration Statement.

      5.5 Access to Information; Confidentiality.

            (a) Access to Information. Subject to the Confidentiality Agreement
and Applicable Law, each of the Company and Parent shall, and shall cause each
of its respective Subsidiaries to, afford to the other party and to the
officers, employees, accountants, counsel, financial advisors and other
representatives of such other party, reasonable access at all reasonable times
on reasonable notice during the period prior to the Effective Time to all their
respective properties, books, contracts, commitments, personnel and records
(provided, that such access shall not unreasonably interfere with the business
or operations of such party) and, during such period and subject to the
Confidentiality Agreement and Applicable Law, each of the Company and Parent
shall, and shall cause each of its respective Subsidiaries to, furnish promptly
to the other party (a) a copy of each report, schedule, registration statement
and other document filed by it during such period pursuant to the requirements
of federal or state securities laws and (b) all other information concerning its
business, properties and personnel as such other party may reasonably request.
No review pursuant to this Section 5.5 shall affect or be deemed to modify any
representation or warranty contained herein, the covenants or agreements of the
parties hereto or the conditions to the obligations of the parties hereto under
this Agreement.

            (b) Confidentiality. Each of the Company and Parent will hold and
keep confidential, and will cause its respective officers and employees and will
direct its accountants, counsel, financial advisors and other representatives
and Affiliates to hold and keep confidential,

                                       56


any nonpublic information in accordance with the terms of the Confidentiality
Agreement, which Confidentiality Agreement will remain in full force and effect.

      5.6 Reasonable Best Efforts.

            (a) Governmental and Third Party Approvals. Upon the terms and
subject to the conditions set forth in this Agreement, each of the parties
agrees to use their reasonable best efforts to take, or cause to be taken, all
actions, and to do, or cause to be done, and to assist and cooperate with the
other parties in doing, all things necessary, proper or advisable under
Applicable Law to consummate and make effective, in the most expeditious manner
practicable, the Merger and the other transactions contemplated by this
Agreement, including (1) the obtaining of all necessary actions or non-actions,
waivers, consents and approvals from Governmental Authorities and the making of
all necessary registrations and filings and the taking of all steps as may be
necessary to obtain an approval or waiver from, or to avoid an action or
proceeding by, any Governmental Authority, including all filings required under
the HSR Act, with the Federal Trade Commission or the United States Department
of Justice and any necessary antitrust, competition or similar laws of any
foreign jurisdiction, (2) the obtaining of all necessary consents, approvals or
waivers from third parties, (3) the defending of any lawsuits or other legal
proceedings, whether judicial or administrative, challenging this Agreement or
the consummation of the transactions contemplated by this Agreement, including
promptly seeking to have any stay or temporary restraining order entered by any
court or other Governmental Authority vacated or reversed, and (4) the execution
and delivery of any additional instruments necessary to consummate the
transactions contemplated by, and to fully carry out the purposes of, this
Agreement. Subject to Applicable Law relating to the exchange of information,
the Company and Parent shall have the right to review in advance, and to the
extent reasonably practicable each will consult the other on, all the
information relating to the Company and its Subsidiaries or Parent and its
Subsidiaries, as the case may be, that appears in any filing made with, or
written materials submitted to, any Governmental Authority or third party in
connection with the Merger and the other transactions contemplated by this
Agreement.

            (b) Notification. Each of the Company and Parent shall keep the
other reasonably apprised of the status of matters relating to the completion of
the transactions contemplated hereby and work cooperatively in connection with
obtaining all required approvals or consents of any Governmental Authority
(whether domestic, foreign or supranational). In that regard, each party shall
without limitation use its reasonable best efforts to: (1) promptly notify the
other of, and if in writing, furnish the other with copies of (or, in the case
of material oral communications, advise the other orally of) any communications
from or with any Governmental Authority (whether domestic, foreign or
supranational) with respect to the Merger or any of the other transactions
contemplated by this Agreement, (2) permit the other to review and discuss in
advance, and consider in good faith the views of the other in connection with,
any proposed written (or any material proposed oral) communication with any such
Governmental Authority with respect to the Merger or any of the other
transactions contemplated by this Agreement, (3) to the extent practical, not
participate in any meeting with any such Governmental Authority with respect to
the Merger or any of the other transactions contemplated by this Agreement
unless it consults with the other in advance and to the extent permitted by such
Governmental Authority gives the other the opportunity to attend and participate
thereat, and (4) furnish the other with such necessary information and
reasonable assistance as the Company or Parent, as

                                       57


applicable, may reasonably request in connection with its preparation of
necessary filings or submissions of information to any such Governmental
Authority. Each of the Company and Parent may, as each deems advisable and
necessary, reasonably designate any competitively sensitive material provided to
the other under this Section 5.6 as "outside counsel only." Such material and
the information contained therein shall be given only to the outside legal
counsel of the recipient and will not be disclosed by such outside counsel to
employees, officers, or directors of the recipient unless express permission is
obtained in advance from the source of the materials (the Company or Parent, as
the case may be) or its legal counsel.

            (c) State Takeover Statutes. In connection with and without limiting
the foregoing, the Company and Parent shall (i) take all action reasonably
necessary to ensure that no state takeover statute or similar statute or
regulation is or becomes applicable to this Agreement or any of the transactions
contemplated hereby and (ii) if any state takeover statute or similar statute or
regulation becomes applicable to this Agreement or any of the transactions
contemplated hereby, take all action reasonably necessary to ensure that such
transactions may be consummated as promptly as practicable on the terms required
by, or provided for, in this Agreement and otherwise to minimize the effect of
such statute or regulation on the Merger and the other transactions contemplated
by this Agreement.

            (d) Divestitures. Notwithstanding anything to the contrary in this
Agreement, neither Parent nor the Company shall be required to hold separate
(including by trust or otherwise) or divest, or take any other action with
respect to, any of its assets or businesses or enter into any consent decree or
other agreement that (1) would reasonably be expected to result in a Material
Adverse Effect on Parent or the Company after the Effective Time or (2) is not
conditional on consummation of the Merger.

      5.7 Indemnification and Insurance.

            (a) Indemnification and Advancement. From and after the Effective
Time, each of Parent and the Surviving Corporation shall, and Parent shall cause
the Surviving Corporation to: (1) indemnify and hold harmless each person who
served as a director or officer of the Company or its Subsidiaries prior to the
Effective Time (collectively, the "COMPANY INDEMNIFIED PARTIES") to the fullest
extent authorized or permitted by Delaware law, as now or hereafter in effect,
in connection with any Claim (as defined below) and any judgments, fines
(including excise taxes), penalties and amounts paid in settlement (including
all interest, assessments and other charges paid or payable in connection with
or in respect of such judgments, fines, penalties or amounts paid in settlement)
resulting therefrom; and (2) promptly pay on behalf of or, within 30 days after
any request for advancement, advance to each of the Company Indemnified Parties,
to the fullest extent authorized or permitted by Delaware law, as now or
hereafter in effect, any Expenses (as defined below) incurred in defending,
serving as a witness with respect to or otherwise participating in any Claim in
advance of the final disposition of such Claim, including payment on behalf of
or advancement to the Company Indemnified Party of any Expenses incurred by such
Company Indemnified Party in connection with enforcing any rights with respect
to such indemnification and/or advancement. The indemnification and advancement
obligations of Parent and the Surviving Corporation pursuant to this Section 5.7
shall extend to acts or omissions occurring at or before the Effective Time and
any Claim relating thereto (including with respect to any acts or omissions
occurring in connection with the approval of this Agreement and the consummation
of the transactions

                                       58


contemplated hereby and any Claim relating thereto) and all rights to
indemnification and advancement conferred hereunder shall continue as to a
person who has ceased to be a director or officer of the Company or its
Subsidiaries prior to the Effective Time and shall inure to the benefit of such
person's heirs, executors and personal and legal representatives. As used in
this Section 5.7, (1) the term "CLAIM" means any threatened, asserted, pending
or completed action, suit or proceeding, or any inquiry or investigation,
whether instituted by the Company or any governmental agency or any other party,
that any Company Indemnified Party in good faith believes might lead to the
institution of any such action, suit or proceeding, whether civil, criminal,
administrative, investigative or other, including any arbitration or other
alternative dispute resolution mechanism, as a result of or in connection with
such Company Indemnified Party's service as a director, officer, trustee,
employee, agent, or fiduciary of the Company or any of its Subsidiaries, or any
employee benefit plan maintained by any of the foregoing at or prior to the
Effective Time; and (2) the term "EXPENSES" means attorneys' fees and all other
costs, expenses and obligations (including, without limitation, experts' fees,
travel expenses, court costs, retainers, transcript fees, duplicating, printing
and binding costs, as well as telecommunications, postage and courier charges)
paid or incurred in connection with investigating, defending, being a witness in
or participating in (including on appeal), or preparing to investigate, defend,
be a witness in or participate in, any Claim for which indemnification is
authorized pursuant to this Section 5.7, including any action relating to a
claim for indemnification or advancement brought by a Company Indemnified Party.

            (b) Certificate of Incorporation, Bylaws and Indemnification
Agreements. In furtherance and not in limitation of Section 5.7(a) hereof, from
and after the Effective Time, each of Parent and the Surviving Corporation
shall, and Parent shall cause the Surviving Corporation to: (1) include and
cause to be maintained in the Surviving Corporation's (or any successor's)
Certificate of Incorporation and Bylaws for a period of at least six years from
and after the Effective Time, provisions regarding elimination of liability of
directors, indemnification of directors, officers and employees and advancement
of expenses which are no less advantageous to the intended beneficiaries than
the corresponding provisions contained in the Company's Certificate of
Incorporation and Bylaws, in each case as in effect on the Agreement Date; and
(2) otherwise keep in full force and effect, and comply with the terms and
conditions of, any agreement in effect as of the Agreement Date between or among
the Company or any of its Subsidiaries and any Company Indemnified Party
providing for the indemnification of such Company Indemnified Party.

            (c) Insurance. For a period of six years after the Effective Time,
Parent shall cause to be maintained in effect the current policies of directors'
and officers' and fiduciary liability insurance maintained by the Company,
including with respect to Claims arising from facts or events which occurred on
or before the Effective Time (including those related to this Agreement and the
transactions contemplated hereby); provided, that Parent may substitute therefor
policies of at least the same coverage and amounts containing terms and
conditions which are no less advantageous to former officers and directors of
the Company; and provided, further, that if the aggregate annual premiums for
such policies at any time during such period will exceed 300% of the per annum
premium rate paid by the Company and its Subsidiaries as of the Agreement Date
for such policies, then Parent shall only be required to provide such coverage
as will then be available at an annual premium equal to 300% of such rate. The
provisions of the immediately preceding sentence shall be deemed to have been
satisfied if

                                       59


prepaid policies have been obtained prior to the Effective Time for purposes of
this Section 5.7(b), which policies provide such directors and officers with
coverage for an aggregate period of six years after the Effective Time,
including with respect to acts or omissions occurring at or prior to the
Effective Time (including with respect to acts or omissions occurring in
connection with approval of this Agreement and consummation of the transactions
contemplated hereby), and nothing in Section 5.1(a) shall prohibit the Company
from obtaining such prepaid policies prior to the Effective Time, provided that
the cost thereof shall not exceed 300% of the per annum premium rate paid by the
Company and its Subsidiaries as of the Agreement Date for such policies. If such
prepaid policies have been obtained prior to the Effective Time, each of Parent
and the Surviving Corporation shall, and Parent shall cause the Surviving
Corporation to, maintain such policies in full force and effect for their
duration.

            (d) Survival of Claims. Notwithstanding anything herein to the
contrary and to the maximum extent permitted by Applicable Law, if any Claim is
made or brought against any Company Indemnified Party on or prior to the sixth
anniversary of the Effective Time, the provisions of this Section 5.7 shall
continue in effect until the final disposition of such Claim.

            (e) Successors. If Parent, the Surviving Corporation or any of their
respective successors or assigns (1) shall consolidate with or merge with or
into any other Person and shall not be the continuing or surviving corporation
or entity of such consolidation or merger or (2) shall transfer all or
substantially all of its properties or assets to any Person, then, in each case,
Parent shall take such action as may be necessary so that such Person shall
assume all of the applicable obligations set forth in this Section 5.7.

            (f) Enforceability. The provisions of this Section 5.7 are (1)
intended to be for the benefit of, and shall be enforceable by, each Company
Indemnified Party (it being expressly agreed that the Company Indemnified
Parties to whom this Section 5.7 applies shall be third party beneficiaries of
this Section 5.7) and (2) in addition to, and not in substitution for, any other
rights to indemnification or contribution that any such Person may have by
contract or otherwise. The obligations of Parent under this Section 5.7 shall
not be terminated or modified in such a manner as to adversely affect the rights
of any Company Indemnified Party under this Section 5.7 without the consent of
such affected Company Indemnified Party.

            (g) Expenses. Parent shall pay (as incurred) all Expenses that a
Company Indemnified Party may incur in enforcing the indemnity, advancement and
other obligations set forth in this Section 5.7.

            (h) Burden of Proof. In connection with any determination as to
whether the Company Indemnified Parties are entitled to the benefits of this
Section 5.7, the burden of proof shall be on the Parent and the Surviving
Corporation to establish that a Company Indemnified Person is not so entitled.

      5.8 Fees and Expenses. Except as set forth in this Section 5.8 and in
Section 7.3, all fees and expenses incurred in connection with the Merger, this
Agreement and the transactions contemplated by this Agreement shall be paid by
the party incurring such fees or expenses, whether or not the Merger is
consummated, except that each of the Company and Parent shall bear and pay
one-half of the costs and expenses incurred by Parent, Merger Sub or the Company
(other than attorneys' fees, accountants' fees and related expenses) in
connection with (a) the

                                       60


filing, printing and mailing of the Registration Statement (including financial
statements and exhibits) and the Proxy Statement/Prospectus (including SEC
filing fees) and any preliminary materials related thereto and (b) the filings
of the premerger notification and report forms under the HSR Act and any
applicable antitrust, competition or similar laws of any foreign jurisdiction
(including filing fees).

      5.9 Public Announcements. The Company and Parent will use reasonable best
efforts to consult with each other before issuing, and will provide each other
the opportunity to review, comment upon and concur with, and use reasonable best
efforts to agree on, any press release or other public statements with respect
to the transactions contemplated by this Agreement, including the Merger, and
shall not issue any such press release or make any such public statement prior
to such consultation, except as either party may determine is required by
Applicable Law, court process or by obligations pursuant to any listing
agreement with any national securities exchange or stock market. In addition,
except to the extent disclosed in or consistent with the Proxy
Statement/Prospectus in accordance with the provisions of Section 5.3 or prior
communications consented to in accordance with this Section 5.9, neither party
shall issue any press release or otherwise make any public statement or
disclosure concerning the other party or the other party's business, financial
condition or results of operations without the consent of such other party,
which consent shall not be unreasonably withheld or delayed. The parties agree
that the initial press release to be issued with respect to the transactions
contemplated by this Agreement shall be in the form agreed to by the parties.

      5.10 Listing. Parent shall use reasonable best efforts to cause the Parent
Common Stock issuable under Article 2 (including those shares of Parent Common
Stock required to be reserved for issuance in connection with the Merger or upon
exercise of Company Options or exchange of Exchangeable Shares from time to
time), to be authorized for listing on the Nasdaq Stock Market, subject to
official notice of issuance, prior to the Closing Date.

      5.11 Tax-Free Reorganization Treatment. Parent and the Company hereby
adopt this Agreement as a plan of reorganization within the meaning of Treasury
Regulations Sections 1.368-2(g) and 1.368-3(a). Parent and the Company intend
that the Merger will qualify as a reorganization within the meaning of Section
368(a) of the Code, and each shall, and shall cause its respective Subsidiaries
to, use its reasonable best efforts to cause the Merger to so qualify. Neither
Parent, Merger Sub nor the Company shall take any action, cause or permit any
action to be taken, or fail to take any action, that would reasonably be
expected to cause the Merger to fail to qualify as a reorganization within the
meaning of Section 368(a) of the Code.

      5.12 Equity Awards and Employee Benefits.

            (a) Notices. As soon as reasonably practicable, but in no event
later than 20 business days following the Effective Time, Parent will issue to
each holder of an Assumed Company Option a document evidencing the assumption of
such Company Option by Parent. The parties shall use their commercially
reasonable efforts to ensure that the conversion of any Company Options which
are intended to be "incentive stock options" (as defined in Section 422 of the
Code) shall be effected in a manner consistent with Section 424(a) of the Code.

            (b) Form S-8. Parent shall file a registration statement on Form S-8
for the shares of Parent Common Stock issuable with respect to Assumed Company
Options, Assumed

                                       61


Restricted Stock Units and other assumed equity compensation awards
(collectively, the "ASSUMED AWARDS") no later than one business day after the
Effective Time and shall exercise commercially reasonable efforts to maintain
the effectiveness of such registration statement for so long as any of such
Assumed Awards remains outstanding.

            (c) Company ESPPs. The Company shall terminate the Company ESPPs
immediately prior to the Effective Time. To the extent any offering period under
the Company ESPPs is in progress prior to such termination, the Company shall
ensure that such offering period ends immediately prior to such termination, and
that each participant's accumulated contributions for such offering period are
applied towards the purchase of Company Common Stock immediately prior to such
termination unless the participant has previously withdrawn from such offering
period in accordance with the terms of such plan. With respect to matters
described in this Section 5.12(c), the Company will communicate with Parent (and
reasonably the communications of Parent) prior to sending any material notices
or other communication materials to its employees.

            (d) Benefit Plans. From and after the Closing Date, Parent shall
provide, or cause to be provided, to those persons who were employees of the
Company or its Subsidiaries immediately prior to the Effective Time and who
remain employees of the Surviving Corporation or its Subsidiaries or become
employees of parent following the Effective Time ("CONTINUING EMPLOYEES")
employee benefits (which shall include each plan, program, policy or arrangement
sponsored by Parent or a Subsidiary of Parent, other than Parent stock option
plans and the Parent ESPP) no less favorable in the aggregate than those
provided to similarly situated employees of Parent. Continuing Employees will be
eligible to participate in Parent stock option plans and the Parent ESPP in
accordance with the terms and conditions of such plans. As promptly as
reasonably practicable after the Effective Time, Continuing Employees shall be
eligible to participate in (1) Parent's employee benefit plans, programs,
policies and arrangements, including any severance plan, medical plan, dental
plan, life insurance plan, vacation program and disability plan, to the extent
permitted by the terms of the applicable plans, programs, policies and
arrangements and (2) such Company Benefit Arrangements, including, but not
limited to, any Company Option Plans, agreements, programs, policies or other
programs sponsored by or maintained by the Company or any of its Subsidiaries,
that are continued by the Company or any of its Subsidiaries following the
Closing Date, or which are assumed by Parent (for the purposes of this Section
5.12(d) only, the "PARENT BENEFIT PLANS"). Continuing Employees shall, to the
extent permitted by Applicable Law receive full credit for purposes of
eligibility, vesting, level of benefits and benefit accrual under the Parent
Benefit Plans in which such Continuing Employees participate for such Continuing
Employees' service with the Company, any of its Subsidiaries, and either of
their predecessors. With respect to any welfare benefit plans maintained by
parent for the benefit of Continuing Employees on and after the Closing Date,
Parent shall (1) cause there to be waived, as required by Applicable Law, any
eligibility requirements or pre-existing condition limitations and (2) give
effect, in determining any deductible maximum out-of-pocket limitations, amounts
paid by such Continuing Employees with respect to similar plans maintained by
the Company and its Subsidiaries, subject to the terms and conditions of the
applicable welfare benefit plans maintained by Parent. Depending upon the date
of the Effective Time relative to the completion of the then-next ending offer
period under the Parent ESPP, and upon the relative benefits and costs, Parent
will determine in good faith whether to establish a special offering period for
Continuing Employees

                                       62


under the Parent ESPP commencing as soon as administratively practicable
following the Effective Time and ending immediately prior to the commencement of
the next regularly scheduled offering period under the Parent ESPP.

            (e) Termination of Benefit Plans. To the extent requested in writing
by Parent no later than ten business days prior to the Closing Date, Company
shall take (or cause to be taken) all actions necessary or appropriate to
terminate, effective no later than the date immediately preceding the Closing
Date, any Company Benefit Arrangement that contains a cash or deferred
arrangement intended to qualify under Section 401(k) of the Code (the "COMPANY
401(K) PLANS") in accordance with the provisions of the Company 401(k) Plans and
Applicable Law. If Parent requests that the Company 401(k) Plans be terminated,
the Company's Board of Directors shall adopt resolutions authorizing the
termination of the Company 401(k) Plans effective no later than the day
immediately preceding the Closing Date.

            (f) Disclaimer. Notwithstanding anything in this Agreement to the
contrary, no provision of this Agreement shall be deemed to (i) guarantee
employment for any period of time for, or preclude the ability of either party
to terminate any continuing employee at will at any time, with or without cause,
for any reason or no reason, (ii) duplicate any benefit provided to any
Continuing Employee or to fund any such benefit not previously funded, or (iii)
subject to the limitations and requirements specifically set forth in this
Section 5.13, require either party to continue any Parent Benefit Arrangement or
Company Benefit Arrangement, or prevent the amendment, modification or
termination thereof, after the Effective Time.

      5.13 Parent Corporate Governance.

            (a) On or prior to the Effective Time, the Board of Directors of
Parent shall cause the number of directors that will comprise the full Board of
Directors of Parent immediately following the Effective Time to be ten. The
members of such Board of Directors immediately following the Effective Time
shall consist of six persons designated prior to the Effective Time by Parent
(which shall include the Chief Executive Officer of Parent) and four persons
designated prior to the Effective Time by the Company (which shall include the
Chief Executive Officer of the Company) (such members, the "INITIAL POST-CLOSING
DIRECTORS").

            (b) On or prior to the Effective Time, Parent shall cause its Bylaws
to be amended to provide that (1) any change in the size of the Board of
Directors prior to the first anniversary of the Effective Time shall require the
prior approval of at least two-thirds of the entire Board of Directors of Parent
and (2) any amendment to the provision in the Bylaws required by the immediately
foregoing clause (1) shall require the prior approval of at least two-thirds of
the entire Board of Directors of Parent.

            (c) Subject to the exercise of the fiduciary duties of the Board of
Directors and Nominating and Governance Committee of Parent, Parent agrees to
cause each of the Initial Post-Closing Directors to be nominated for election at
the next annual meeting of its stockholders, unless in each case such Initial
Post-Closing Director shall have resigned, retired or otherwise become unable to
serve prior to such annual meeting.

                                       63


            (d) Each of Parent and the Company agrees to cause each member of
its Board of Directors that is not an Initial Post-Closing Director to resign

be entitled to place appropriate legends on the certificates evidencing any
shares of Company Common Stock to be received by Rule 145 Affiliates in the
Merger reflecting the restrictions set forth in Rule 145 promulgated under the
Securities Act and to issue appropriate stop transfer instructions to the
transfer agent for Parent Common Stock (provided, that such legends or stop
transfer instructions shall be removed, one year after the Effective Time, upon
the request of any holder of shares of Parent Common Stock issued in the Merger
if such holder is not then a Rule 145 Affiliate or an Affiliate of Parent).

      5.15 Notification of Certain Matters. The Company shall give prompt notice
to Parent and Parent shall give prompt notice to the Company, as the case may
be, if it determines that any Effect has had a Material Adverse Effect on such
party or would result in the failure of any of the conditions set forth in
Article 6 to be satisfied. Notwithstanding the above, the delivery of any notice
pursuant to this Section 5.16 will not limit or otherwise affect the remedies
available hereunder to the party receiving such notice or the conditions to such
party's obligation to consummate the Merger.

      5.16 Section 16 Matters. Prior to the Effective Time, each of the Company
and Parent shall take all such steps as may be required (to the extent permitted
under Applicable Law) to cause any dispositions of Company Common Stock
(including derivative securities with respect to Company Common Stock) or
acquisitions of Parent Common Stock (including derivative securities with
respect to Parent Common Stock) resulting from the transactions contemplated by
this Agreement by each individual who is subject to the reporting requirements
of Section 16(a) of the Exchange Act with respect to the Company to be exempt
under Rule 16b-3 promulgated under the Exchange Act, such steps to be taken in
accordance with the No-Action Letter, dated January 12, 1999, issued by the SEC
to Skadden, Arps, Slate, Meagher & Flom LLP. The parties acknowledge that all
such above referenced dispositions and acquisitions are compensatory in nature.

Agreement) or terminate the Company Rights Agreement unless required to do so by
order of a court of competent jurisdiction.

            (b) Parent Rights Plan. Prior to the Effective Time, Parent shall

jurisdiction or (ii) the Company's or Parent's Board of Directors, as the case
may be, has concluded in good faith, after consultation with its outside legal
counsel, that, in light of a Superior Proposal with respect to the Company or
Parent, as applicable, the failure to take such action would be inconsistent
with the Board of Directors' fiduciary duties under Applicable Law.

      5.18 Reservation of Parent Common Stock. Effective at or prior to the
Effective Time, Parent shall reserve (free from preemptive rights) out of its
reserved but unissued shares of Parent Common Stock, for the purposes of
effecting the conversion of the issued and outstanding shares of Company Common
Stock and assumption of Company Options pursuant to this Agreement and the

debentures due August 1, 2013 to the extent required by the terms of such
debentures and the instruments and agreements relating thereto.

      7.3 Payments.

            (a) Payment by the Company. In the event that this Agreement is
terminated by the Company pursuant to Section 7.1(b)(4) or by Parent pursuant to
any of Section 7.1(b)(4), Section 7.1(d) (but, in the case of Section 7.1(d),
only if such termination is due to an intentional breach of any representation,
warranty or covenant by the Company) or Section 7.1(f), the Company shall
promptly, but in no event later than two business days after the date of such

if following the Agreement Date and prior to such termination, any Person shall
have made to the Company or its stockholders (in the case of Section 7.1(d)), or
publicly announced (in the case of Section 7.1(b)(4) or Section 7.1(d)), an
Alternative Transaction Proposal with respect to the Company and within 12
months following termination of this Agreement, any Alternative Transaction with
respect to the Company is consummated or the Company enters into an agreement

            (b) Payment by Parent. In the event that this Agreement is
terminated by Parent pursuant to Section 7.1(b)(3) or by the Company pursuant to

Parent acknowledges that the agreements contained in this Section 7.3 are an
integral part of the transactions contemplated by this Agreement and that,
without these agreements, the other party hereto would not enter into this
Agreement. Accordingly, if the Company or Parent, as the case may be, fails to
pay in a timely manner the amounts due pursuant to this Section 7.3 and, in
order to obtain such payment, the other party hereto makes a claim that results
in a judgment against the party failing to pay for the amounts set forth in this
Section 7.3, the party so failing to pay shall pay to the other party its
reasonable costs and expenses (including reasonable attorneys' fees and
expenses) in connection

                                       70


with such suit, together with interest on the amounts set forth in this Section
7.3 at the rate of interest per annum publicly announced by Bank of America as

damages incurred in the event of breach of this Agreement, to the extent
permitted by Section 7.2.

      7.4 Amendment. Subject to compliance with Applicable Law, this Agreement
may be amended by the parties at any time before or after the Company
Stockholder Approval or the Parent Stockholder Approval; provided, however, that
after the occurrence of either the Company Stockholder Approval or the Parent
Stockholder Approval there may not be, without further approval of the
stockholders of the Company and Parent, any amendment of this Agreement that
changes the amount or the form of the consideration to be delivered to the
holders of Company Common Stock hereunder, or which by Applicable Law otherwise
expressly requires the further approval of such stockholders. This Agreement may
not be amended except by an instrument in writing signed on behalf of each of
the parties hereto and duly approved by the parties' respective Boards of
Directors or a duly designated committee thereof.

may, subject to Applicable Law, (a) extend the time for the performance of any

inaccuracies in the representations and warranties of the other parties
contained in this Agreement or in any document delivered pursuant to this
Agreement or (c) waive compliance by the other party hereto with any of the
agreements or conditions contained in this Agreement. Any agreement on the part

an instrument in writing signed on behalf of such party. Any extension or waiver
given in compliance with this Section 7.5 or failure to insist on strict
compliance with an obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.
