      This AGREEMENT AND PLAN OF MERGER (hereinafter called this "Agreement"),
dated as of April 28, 2002, is made and entered into by and among FAIR, ISAAC

a Delaware corporation (the "Company"), and NORTHSTAR ACQUISITION INC., a
Delaware corporation and a wholly-owned subsidiary of Parent ("Merger Sub").

                                    RECITALS

      WHEREAS, the respective boards of directors of each of Parent, Merger Sub
and the Company have approved and declared advisable this Agreement and the
merger of Merger Sub with and into the Company on the terms and subject to the
conditions set forth in this Agreement (the "Merger") and have determined that
the Merger and the other transactions contemplated by this Agreement are fair
to, and in the best interest of, their respective stockholders; and

      WHEREAS, it is the intention of the parties that the Merger qualify as a
"reorganization" pursuant to Section 368 of the Internal Revenue Code of 1986,
as amended (the "Code");

      NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained herein, the parties hereto agree as follows:

effected pursuant to Section 251 of the General Corporation Law of the State of
Delaware, as amended (the "DGCL") and the separate corporate existence of Merger
Sub shall thereupon cease. The Company shall be the surviving corporation in the
Merger (sometimes hereinafter referred to as the "Surviving Corporation") and
shall continue to be governed by the laws of the State of Delaware, and the
separate corporate existence of the Company with all its rights, privileges,
immunities, powers and franchises shall continue unaffected by the Merger,
except as set forth in Articles II and III. The Merger shall have the effects
specified in the DGCL.

      1.2 Closing. Subject to the terms and conditions of this Agreement, the

A.M. on the first business day on which the last to be fulfilled or waived of
the conditions set forth in Article VII (other than those conditions that by
their nature are to be satisfied at the Closing, but subject to the fulfillment
or waiver of those conditions) shall be satisfied or waived in accordance with
this Agreement or (ii) at such other place and time and/or on such other date as
the Company and Parent may agree in writing (the "Closing Date").


                                      -1-

      1.3 Effective Time. As soon as practicable following the Closing, the
Company will cause a Certificate of Merger (the "Certificate of Merger") to be
executed, acknowledged and filed with the Secretary of State of the State of
Delaware as provided in Section 251 of the DGCL. The Merger shall become
effective at the time when the Certificate of Merger has been duly filed with
the Secretary of State of Delaware or, if agreed to by Parent and the Company,
such later time or date as may be set forth in the Certificate of Merger in
accordance with the DGCL (the "Effective Time").

                                   ARTICLE II

                     CERTIFICATE OF INCORPORATION AND BYLAWS

                          OF THE SURVIVING CORPORATION

      2.1 The Certificate of Incorporation. The certificate of incorporation of
the Company as in effect immediately prior to the Effective Time shall be

Exhibit A, and as so amended shall be the restated certificate of incorporation
of the Surviving Corporation (the "Charter").

      2.2 The Bylaws. The bylaws of Merger Sub as in effect immediately prior to
the Effective Time shall be the bylaws of the Surviving Corporation (the
"Bylaws"), until thereafter amended as provided therein or by applicable law.

                           CERTAIN GOVERNANCE MATTERS

      3.1 Directors of the Surviving Corporation. The directors of Merger Sub at

accordance with the Charter and Bylaws.

      3.2 Officers of the Surviving Corporation. The officers of the Company at
the Effective Time shall, from and after the Effective Time, be the officers of
the Surviving Corporation until their successors have been duly elected or

immediately prior to the Effective Time and (b) two persons designated by Parent
prior to the Effective Time ("Additional Board Designees") who are either (i)
directors of the Company immediately prior to the Effective Time or (ii) other

two Additional Board Designees who are not directors of the Company, such
Additional Board Designee(s) shall be reasonably acceptable to the Company.
Prior to the Effective Time, the Board of Directors of Parent shall take all
necessary action to increase the size of the Board of Directors of Parent as
necessary and to elect the Additional Board Designees to the Board of Directors
of Parent, in each case as of the Effective Time.


                                      -2-

                                   ARTICLE IV

         EFFECT OF THE MERGER ON CAPITAL STOCK; EXCHANGE OF CERTIFICATES

      4.1 Effect on Capital Stock. At the Effective Time, as a result of the
Merger and without any action on the part of the holder of any capital stock of
the Company, the following shall occur:

      (a) Merger Consideration.

                  (i) Each share of common stock, par value $0.001 per share, of
the Company (each a "Share" or, collectively, the "Shares") that is issued and
outstanding immediately prior to the Effective Time (other than Excluded Shares,
as defined below), shall, subject to Section 4.2(e), be converted into the right
to receive, and become exchangeable for, 0.346 shares (the "Exchange Ratio") of
common stock, par value $0.01 per share of Parent (the "Parent Common Stock").
As used herein: (A) the term "Merger Consideration" means the shares of Parent
Common Stock payable in respect of Shares upon consummation of the Merger in
accordance with this Section 4.1; and (B) the term "Excluded Shares" means,
collectively, (i) Shares owned by Parent or any direct or indirect Subsidiary of
Parent, and (ii) Shares that are owned by the Company or any direct or indirect
Subsidiary of the Company (and in each case not held on behalf of third
parties).

                  (ii) Parent agrees that pursuant to the Parent Rights
Agreement a Parent Right (as those terms are defined in Section 5.1(b)(ii)
below) shall be issued with each share of Parent Common Stock issued as Merger
Consideration.

                  (iii) At the Effective Time, all Shares that are issued and
outstanding immediately prior to the Effective Time shall cease to be
outstanding and shall be canceled and retired and shall cease to exist, and each
certificate (a "Certificate") formerly representing any of such Shares (other
than Excluded Shares) shall thereafter represent only the right to receive (A)
the Merger Consideration payable in respect of such Shares under Section
4.1(a)(i), (B) cash in lieu of fractional shares pursuant to Section 4.2(e), if
any, and (C) an amount equal to any distribution or dividend pursuant to Section
4.2(c).

      (b) Cancellation of Excluded Shares. At the Effective Time, each Excluded
Share that is issued and outstanding immediately prior to the Effective Time
shall, by virtue of the Merger and without any action on the part of the holder
thereof, cease to be outstanding, shall be canceled and retired without payment
of any consideration therefor and shall cease to exist.

      (c) Merger Sub. At the Effective Time, each share of common stock, par
value $0.01 per share, of Merger Sub that is issued and outstanding immediately
prior to the Effective Time shall be converted into one share of common stock of
the Surviving Corporation.

      4.2 Exchange of Certificates for Shares.

      (a) Exchange Agent. As of the Effective Time, Parent shall deposit, or
shall cause to be deposited, with an exchange agent selected by Parent and
reasonably acceptable to the Company (the "Exchange Agent"), for the benefit of
the holders of Shares, certificates


                                      -3-

representing the shares of Parent Common Stock and, after the Effective Time, if
applicable, any cash, dividends or other distributions with respect to the
Parent Common Stock to be issued or paid pursuant to Section 4.1(a)(i)
(including cash in lieu of fractional shares) to be exchanged for Shares
outstanding immediately prior to the Effective Time upon due surrender of the
Certificates (or affidavits of loss in lieu thereof) pursuant to the provisions
of this Article IV (such certificates for shares of Parent Common Stock,
together with the amount of any dividends or other distributions payable with
respect thereto and any cash in lieu of fractional shares, being collectively
hereinafter referred to as the "Exchange Fund").

      (b) Exchange Procedures. Promptly after the Effective Time (but in no
event later than ten (10) business days after the Effective Time), Parent shall
cause the Exchange Agent to mail to each holder of record of Shares (other than
holders of Excluded Shares) (i) a letter of transmittal specifying that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates (or affidavits of loss in lieu thereof)
to the Exchange Agent and (ii) instructions for use in effecting the surrender
of the Certificates in exchange for (A) certificates representing shares of
Parent Common Stock and (B) any unpaid dividends and other distributions and
cash in lieu of fractional shares. Subject to Section 4.2(h), upon surrender of
a Certificate to the Exchange Agent together with such letter of transmittal,
duly executed, the holder of such Certificate shall be entitled to receive in
exchange therefor (x) a certificate representing that number of whole shares of
Parent Common Stock that such holder is entitled to receive pursuant to this
Article IV and (y) a check in the amount (after giving effect to any required
tax withholdings) of (A) any cash in lieu of fractional shares plus (B) any
unpaid cash dividends that such holder has the right to receive pursuant to the
provisions of this Article IV and (z) any other non-cash dividends or other
distributions that such holder has the right to receive pursuant to the
provisions of this Article IV. No interest will be paid or accrued on any amount
payable upon due surrender of the Certificates. In the event of a transfer of
ownership of Shares that is not registered in the transfer records of the
Company, a certificate representing the proper number of shares of Parent Common
Stock, together with a check for any cash to be paid upon due surrender of the
Certificate and any other cash dividends or distributions in respect thereof and
any other non-cash dividends that such holder has the right to receive pursuant
to the provisions of this Article IV, may be issued and/or paid to such a
transferee if the Certificate formerly representing such Shares is presented to
the Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and to evidence that any applicable stock transfer taxes have been
paid. If any certificate for shares of Parent Common Stock is to be issued in a
name other than that in which the Certificate surrendered in exchange therefor
is registered, it shall be a condition of such exchange that the Person (as
hereinafter defined) requesting such exchange shall pay any transfer or other
taxes required by reason of the issuance of certificates of shares of Parent
Common Stock in a name other than that of the registered holder of the
Certificate surrendered, or shall establish to the satisfaction of Parent or the
Exchange Agent that such tax has been paid or is not applicable.

            As used in this Agreement, "Person" means any individual,
corporation (including not-for-profit), general or limited partnership, limited
liability company, joint venture, estate, trust, association, organization,
Governmental Entity (as defined in Section 5.1(d)) or other entity of any kind
or nature.


                                      -4-

      (c) Distributions with Respect to Unexchanged Shares. In the event that a
dividend or other distribution is declared by Parent in respect of the Parent
Common Stock, the record date for which is at or after the Effective Time, that
declaration shall include dividends or other distributions in respect of all
shares of Parent Common Stock issuable pursuant to this Agreement. No such
dividend or other distribution in respect of the Parent Common Stock shall be
paid to any holder of any unsurrendered Certificate until such Certificate is
surrendered for exchange in accordance with this Article IV. Subject to the
effect of applicable laws, following surrender of any such Certificate, there
shall be issued and/or paid to the holder of the certificates representing whole
shares of Parent Common Stock issued in exchange therefor, without interest, (A)
at the time of such surrender, an amount equal to the dividends or other
distributions with a record date after the Effective Time theretofore payable
with respect to such whole shares of Parent Common Stock and not paid and (B) at
the appropriate payment date, the dividends or other distributions payable with
respect to such whole shares of Parent Common Stock with a record date after the
Effective Time but with a payment date subsequent to surrender.

      (d) Transfers. After the Effective Time, there shall be no transfers on
the stock transfer books of the Company of the Shares that were outstanding
immediately prior to the Effective Time.

      (e) Fractional Shares. Notwithstanding any other provision of this
Agreement, no fractional shares of Parent Common Stock will be issued and any
holder of Shares entitled to receive a fractional share of Parent Common Stock
but for this Section 4.2(e) shall be entitled to receive upon surrender of their
Certificates a cash payment in lieu of such fractional share, without interest,
which payment shall represent such holder's proportionate interest in the net
proceeds from the sale by the Exchange Agent on behalf of such holder of the
aggregate fractional shares of Parent Common Stock that such holder otherwise
would be entitled to receive. Any such sale shall be made by the Exchange Agent
as soon as practicable after the Effective Time at the then prevailing prices on
the New York Stock Exchange ("NYSE").

      (f) Termination of Exchange Fund. Any portion of the Exchange Fund
(including the proceeds of any investments thereof and any Parent Common Stock)
that remains unclaimed by the stockholders of the Company for 90 days after the
Effective Time shall be paid to Parent. Any stockholders of the Company who have
not theretofore complied with this Article IV shall thereafter look only to
Parent for payment of their shares of Parent Common Stock and any cash,
dividends and other distributions in respect of the Parent Common Stock payable
and/or issuable pursuant to Section 4.1 and Section 4.2(c) upon due surrender of
their Certificates (or affidavits of loss in lieu thereof), in each case,
without any interest thereon. Notwithstanding the foregoing, none of Parent, the
Surviving Corporation, the Exchange Agent or any other Person shall be liable to
any former holder of Shares for any amount properly delivered to a public
official pursuant to applicable abandoned property, escheat or similar laws.

      (g) Lost, Stolen or Destroyed Certificates. In the event any Certificate
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the Person claiming such Certificate to be lost, stolen or
destroyed and, if required by Parent, the posting by such Person of a bond in an
amount determined by Parent as indemnity against any claim that may be made
against it with respect to such Certificate, the Exchange Agent will issue in
exchange for such lost, stolen or destroyed Certificate the shares of Parent
Common Stock and any cash


                                      -5-

payable and any unpaid dividends or other distributions in respect of Parent
Common Stock pursuant to Section 4.2(c) upon due surrender of and deliverable in
respect of the Shares formerly represented by such Certificate pursuant to this
Agreement.

      4.3 Appraisal Rights. In accordance with Section 262 of the DGCL, no
appraisal rights shall be available to holders of Shares or Parent Common Stock
in connection with the Merger.

      4.4 Equitable Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect appropriately and equitably the effect of any stock split,
reverse stock split, stock dividend (including any dividend or distribution of
securities convertible into or exercisable for Shares or Parent Common Stock),
reorganization, recapitalization or other like change with respect to the Shares
or to the Parent Common Stock occurring on or after the date hereof and prior to
the Effective Time. Consistent with the foregoing, Parent and the Company agree
that payment of the Parent Stock Dividend (as defined in Section 6.2(d)) will
have the effect of adjusting the Exchange Ratio to equal 0.519 shares of Parent
Common Stock (assuming no other adjustment to the Exchange Ratio under this
Section 4.4).

      4.5 Assumption of Stock Options. Upon the Effective Time, the stock
options of the Company that are Company Options (as defined in Section
5.1(b)(i)) and are outstanding immediately prior to the Effective Time shall be
assumed by Parent and shall become options to purchase Parent Common Stock as
provided in Section 6.12.

                                   ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

      5.1 Representations and Warranties of the Company, Parent and Merger Sub.
Except as set forth in the corresponding sections or subsections of the
disclosure letter, dated the date hereof, delivered by the Company to Parent or
by Parent to the Company (each a "Disclosure Letter" and the "Company Disclosure
Letter" and the "Parent Disclosure Letter," respectively), as the case may be,
the Company (except for subparagraphs 5.1(b)(ii), 5.1(b)(iii), 5.1(c)(ii),
5.1(p)(ii) and the third and seventh sentences of subparagraph 5.1(e)) hereby
represents and warrants to Parent and Merger Sub, and Parent (except for
subparagraphs 5.1(b)(i), 5.1(c)(i), 5.1(n)(ii) through (v), 5.1(p)(i) and the
second and sixth sentences of subparagraph 5.1(e)), on behalf of itself and
Merger Sub, hereby represents and warrants to the Company that:

      (a) Organization, Good Standing and Qualification. Each of it and its
Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its respective jurisdiction of organization and has
all requisite corporate or similar power and authority to own and operate its
properties and assets and to carry on its business as presently conducted and is
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction where the ownership or operation of its properties or conduct
of its business requires such qualification, except where the failure to be so
qualified or in good standing, when taken together with all other such failures,
is not reasonably likely to have a Material Adverse Effect on it (as hereinafter
defined). It has made available to Parent, in the case of the Company, and to
the Company, in the case of Parent and Merger Sub, a complete and correct copy
of its and its


                                      -6-

Subsidiaries' certificates of incorporation and bylaws, or other governing
documents as applicable, each as amended to date. Such certificates of
incorporation and bylaws, or other governing documents, so delivered are in full
force and effect. Section 5.1(a) of its respective Disclosure Letter contains a
correct and complete list of each jurisdiction where it and each of its
Subsidiaries is organized and qualified to do business. Since the date of its
incorporation, Merger Sub has not engaged in any activities other than in
connection with or as contemplated by this Agreement.

      As used in this Agreement:

            (i) "Subsidiary" means, with respect to the Company, Parent or
Merger Sub, as the case may be, any entity, whether incorporated or
unincorporated, of which at least a majority of the issued and outstanding
securities or ownership interests having by their terms ordinary voting power to
elect a majority of the Board of Directors or other persons performing similar
functions is directly or indirectly owned or controlled by such party or by one
or more of its respective Subsidiaries or by such party and any one or more of
its respective Subsidiaries;

            (ii) "Material Adverse Effect" means, with respect to any Person,
any change, event, violation, inaccuracy, circumstance or effect (any such item,
an "Effect") that is materially adverse to the condition (financial or
otherwise), properties, assets (including intangible assets), business or
results of operations of such Person and its Subsidiaries, taken as a whole;

as amended (the "HSR Act"), (C) under the Exchange Act, (D) contemplated by
Section 6.3 (which include the filing of the Registration Statement), (E)
otherwise required to be made by Parent, the Company or Merger Sub under the

the Merger or any of the transactions contemplated by this Agreement, and (F)
required to be made with governmental or regulatory authorities in any
jurisdiction outside the United States, no notices, reports or other filings are
required to be made with, nor are any consents, registrations, approvals,
permits or authorizations required to be obtained by it from, any supranational,

                                      -10-

exercising any regulatory or governmental or quasi-governmental authority (a

of, or a default under, its certificate of incorporation or bylaws or other
governing documents or the comparable governing instruments of any of its
Significant Subsidiaries, (B) (with or without notice, lapse of time or both) a
breach or violation of, or a default under, the acceleration of any obligations

binding upon it or any of its Subsidiaries or any Law (as defined in Section

of its Subsidiaries is subject or (C) any change in the rights or obligations of
any party under any of its Contracts, except, in the case of clause (B) or (C)

of, or default under, such Contracts.

      (e) Reports; Financial Statements. It has, and, to the extent applicable,

and any Reports filed with the SEC subsequent to the date hereof will not,
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements made therein,
in light of the circumstances in which they were made, not misleading. Each of

as of its date and each of the consolidated statements of income and of changes

position, as the case may be, of it and its Subsidiaries for the periods set

year-end audit adjustments that will not be material in amount or effect), in
each case in accordance with generally accepted accounting principles ("GAAP")
consistently applied during the periods involved, except as permitted by SEC

conducted their respective businesses in all material respects only in, and have
not engaged in any material transaction other than according to, the ordinary
and usual course of such businesses and there has not been (i) any change in the
condition (financial or otherwise), properties, assets (including intangible
assets), business or results of operations of it and its Subsidiaries, except
those changes that, individually or in the aggregate, have not had, and are not
reasonably likely to have, a Material Adverse Effect on it; (ii) any material
damage, destruction or other casualty loss with respect to any material asset or
property owned, leased or otherwise used by it or any of its Subsidiaries,

except as provided for herein, as disclosed in Section 5.1(f) of its respective
Disclosure Letter or as disclosed in its Reports filed prior to the date hereof,
there has not been any increase in the compensation payable or that


                                      -12-

could become payable by it or any of its Subsidiaries to (x) its officers or (y)
any key employees of it or its Subsidiaries, or any officers of its
Subsidiaries, whose annual cash compensation is $250,000 or more, or any
amendment of any of its Compensation and Benefit Plans.

      (g) Litigation and Certain Liabilities. Except as disclosed in Section
5.1(g) of its respective Disclosure Letter or as disclosed in its Reports filed
prior to the date hereof and except for matters which are not, individually or
in the aggregate, reasonably likely to have a Material Adverse Effect on it or
prevent or materially delay or materially impair its ability to consummate the
transactions contemplated by this Agreement, there are no (i) civil, criminal or
administrative actions, suits, claims, hearings, investigations or proceedings
pending or, to its knowledge, threatened against it or any of its Subsidiaries
or (ii) obligations or liabilities (other than those reflected or reserved
against on its balance sheet at December 31, 2001, to the extent so reflected or
reserved), whether or not accrued, contingent or otherwise and whether or not
required to be disclosed, including those relating to matters involving any
Environmental Law (as defined in Section 5.1(k)) or any other facts or
circumstances of which it has knowledge, that are reasonably likely to result in
any suits, demands or claims against, or obligations or liabilities of, it or
any of its Subsidiaries.

      (h) Employee Benefits.

                  (i) A copy of each bonus, deferred compensation, pension,
retirement, profit-sharing, thrift, savings, employee stock ownership, stock
bonus, stock purchase, restricted stock, stock option, employment, termination,
severance, compensation, medical, health or other welfare plan, agreement,

severance or other benefits in excess of those provided for under the standard
policies of Company or Parent, as the case may be, and except for stock option
agreements evidencing stock options scheduled in Section 5.1(b) of the Company
Disclosure Letter or Section 5.1(b) of the Parent Disclosure Letter, as
applicable (the "Compensation and Benefit Plans") and any trust agreement or
insurance contract forming a part of such Compensation and Benefit Plans has
been made available to Parent, in the case of the Company, and to the Company,
in the case of Parent, prior to the date hereof. The Compensation and Benefit
Plans existing as of the date hereof are listed in Section 5.1(h)(i) of its
respective Disclosure Letter and any "change of control" or similar provisions
therein which will be effected by the Merger are specifically identified in
Section 5.1(h)(i) of its respective Disclosure Letter.

                  (ii) All of its Compensation and Benefit Plans are in
substantial compliance with all applicable law including the Code and the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"). Each
Compensation and Benefit Plan that is an "employee pension benefit plan" within
the meaning of Section 3(2) of ERISA (a "Pension Plan"), that is intended to be
qualified under Section 401(a) of the Code and is not a standard prototype plan
has received a favorable determination letter from the Internal Revenue Service
(the "IRS"), has applied for such letter in a timely fashion, or has a remaining
period of time within which to apply for such a letter, and it is not aware of
any circumstances likely to result in revocation of any such favorable
determination letter. There is no pending or, to its knowledge, threatened
material litigation relating to the Compensation and Benefit Plans. Neither it
nor any


                                      -13-

of its Subsidiaries has engaged in a transaction with respect to any
Compensation and Benefit Plan that, assuming the taxable period of such
transaction expired as of the date hereof, would subject it or any of its
Subsidiaries to fiduciary liability payment of additional benefits or a material
tax or penalty imposed by either Section 4975 of the Code or Section 502 of
ERISA.

                  (iii) As of the date hereof, it does not maintain or
contribute to an employee pension benefit plan subject to Title IV of ERISA or
Section 412 of the Code.

                  (iv) Except as set forth in Section 5.1(h)(iv) of its
respective Disclosure Letter, neither it nor its Subsidiaries have any
obligations for retiree health and life benefits under any Compensation and
Benefit Plan. It or its Subsidiaries may amend or terminate any such plan under
the terms of such plan at any time without incurring any material liability
thereunder.

                  (v) Except as set forth in Section 5.1(h)(v) of the its
respective Disclosure Letter, the consummation of the Merger and the other
transactions contemplated by this Agreement will not (x) entitle any of its
employees or employees of its Subsidiaries to severance pay, (y) accelerate the
time of payment or vesting or trigger any payment of compensation or benefits
under, increase the amount payable or trigger any other material obligation
pursuant to, any of the Compensation and Benefit Plans or (z) result in any
breach or violation of, or a default under, any of the Compensation and Benefit
Plans.

                  (vi) To its knowledge, all Compensation and Benefit Plans
covering current or former non-U.S. employees or former employees of it and its
Subsidiaries comply in all material respects with applicable local law. It and
its Subsidiaries have no material unfunded liabilities with respect to any
Pension Plan that covers such non-U.S. employees.

      (i) Compliance with Laws. Except as set forth in Schedule 5.1(i) or in its
Reports filed prior to the date hereof, the businesses of each of it and its
Subsidiaries have not been, and are not being, conducted in violation of any
law, ordinance, regulation, judgment, order (whether temporary, preliminary or
permanent), decree, arbitration award, license or permit of any Governmental
Entity (collectively, "Laws"), except for violations or possible violations
that, individually or in the aggregate, are not reasonably likely to have a
Material Adverse Effect on it or prevent, materially delay, materially burden or
materially impair its ability to consummate the transactions contemplated by
this Agreement or materially impair the ability of the Surviving Corporation,
Parent or any of their respective affiliates, following consummation of the
Merger, to conduct any material business or operations in any jurisdiction in
which they are now being conducted. Except as set forth in its Reports filed
prior to the date hereof, no investigation or review by any Governmental Entity
with respect to it or any of its Subsidiaries is pending or, to its knowledge,
threatened, nor has any Governmental Entity indicated an intention to conduct
the same, except for those the outcome of which are not, individually or in the
aggregate, reasonably likely to have a Material Adverse Effect on it or prevent
or materially delay, materially burden or materially impair its ability to
consummate the transactions contemplated by this Agreement or materially impair
the ability of the Company, the Surviving Corporation, Parent or any of their
respective affiliates, following consummation of the Merger, to conduct any
material business or operations in any jurisdiction where they are now being
conducted. To its knowledge, no material change is required in its or any of its
Subsidiaries' processes, properties or procedures in


                                      -14-

connection with any such Laws, and it has not received any notice or
communication of any material noncompliance with any such Laws that has not been
cured as of the date hereof.

      (j) Takeover Statutes. Its Board of Directors has taken all necessary
action to approve the transactions contemplated by this Agreement such that the
restrictions under Section 203 of the DGCL shall not apply to such transactions.
No "fair price," "moratorium," "control share acquisition" or other similar
antitakeover statute or regulation (each, an "Takeover Statute") is applicable
to it, the Shares, the Merger Consideration, the Merger, this Agreement or the
other transactions contemplated by this Agreement.

      (k) Environmental Matters. Except as disclosed in Section 5.1(k) of its
respective Disclosure Letter or in its Reports filed prior to the date hereof:
(i) it and its Subsidiaries have complied in all material respects with all
applicable Environmental Laws; (ii) neither it nor its Subsidiaries have any
material liability under any Environmental Law for any Hazardous Substance

         6.3 Prospectus/Proxy Statement and Registration Statement; Comfort
Letter.

         (a) As promptly as practicable after the execution of this Agreement
(and within twenty-one (21) days after the date hereof if reasonably possible),
Parent and the Company shall prepare and Parent shall file with the SEC a
Registration Statement on Form S-4 (the "Registration Statement") with respect
to the registration of the Parent Stock Issuance under the Securities Act and
containing, in addition to a prospectus covering the Parent Stock Issuance, a
proxy statement in connection with the vote of stockholders of the Company to
approve and adopt this Agreement and to approve the Merger and a proxy statement
in connection with the vote of stockholders of Parent to approve the Parent
Stock Issuance (the "Prospectus/Proxy Statement"). Parent and the Company will
provide each other with any information which may be required in order to
effectuate the preparation and filing of the Prospectus/Proxy Statement and the
Registration Statement pursuant to this Section 6.3 and Parent will provide the
Company a reasonable time to review and comment on each draft and each amendment
of or supplement to the Registration Statement. Each of Parent and the Company
will promptly respond to any comments from the SEC, will use reasonable best
efforts to cause the Registration Statement to be declared effective under the
Securities Act as promptly as practicable after such filing and to keep the
Registration Statement effective as long as is necessary to consummate the
Merger and the transactions contemplated hereby. Each of Parent and the Company
will notify the other promptly upon the receipt of any comments from the SEC or
its staff in connection with the filing of, or amendments or supplements to, the
Registration Statement and/or the Prospectus/Proxy Statement. Whenever any event
occurs which, in the good faith judgment of Parent or the Company, as the case
may be, is required to be set forth in an amendment or supplement to the
Prospectus/Proxy Statement or the Registration Statement, Parent or the Company,
as the case may be, will promptly inform the other of such occurrence and
cooperate in filing with the SEC, or its staff, and/or mailing to stockholders
of Parent and/or the Company, such amendment or supplement. Each of Parent and
the Company shall cooperate and provide the other (and its counsel) with a
reasonable opportunity to review and comment on any amendment or supplement to
the Registration Statement and Prospectus/Proxy Statement prior to filing such
with the SEC, and will provide each other with a copy of such filings made with
the SEC. Each of Parent and the Company will cause the Prospectus/Proxy
Statement to be mailed to its respective stockholders at the earliest
practicable time after the Registration Statement is declared effective by the
SEC.

         (b) Each of the Company and Parent agrees that none of the information
supplied or to be supplied by it for inclusion or incorporation by reference in
the Registration Statement will, at the time the Registration Statement 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, in the light of the
circumstances under which they are made, not misleading. None of the information
supplied or to be supplied by it

                                      -26-

for inclusion or incorporation by reference in the Prospectus/Proxy Statement
will, at the time the Prospectus/Proxy Statement is mailed to its stockholders,
at the time of its Stockholders' Meeting (as defined in Section 6.4(a)) 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 the light of the circumstances under which they
are made, not misleading. The Prospectus/Proxy Statement will comply as to form
in all material respects with the provisions of the Exchange Act and the rules
and regulations promulgated by the SEC thereunder. Notwithstanding the
foregoing, no representation or warranty is made by the Company with respect to
statements made or incorporated by reference therein about Parent or supplied by
Parent for inclusion or incorporation by reference in the Registration Statement
or the Prospectus/Proxy Statement and no representation or warranty is made by
Parent with respect to statements made or incorporated by reference therein
about the Company that are supplied by the Company for inclusion or
incorporation by reference in the Registration Statement or Prospectus/Proxy
Statement.

         (c) The Company shall use its reasonable best efforts to cause to be
delivered to Parent and its directors a letter of its independent auditors,
dated (i) the date on which the Registration Statement shall become effective
and (ii) not more than two business days prior to the Effective Time, and
addressed to the Company and its directors and Parent and its directors, in form
and substance customary for "comfort" letters delivered by independent public
accountants in connection with registration statements similar to the
Registration Statement.

         6.4 Meetings of Stockholders; Board Recommendation.

         (a) Meeting of Stockholders. Promptly after the Registration Statement
is declared effective under the Securities Act, each of Parent and Company will
take all action necessary in accordance with the DGCL and its respective
certificate of incorporation and bylaws to call, hold and convene a meeting of
its respective stockholders to consider, in the case of Parent, the Parent Stock
Issuance, and, in the case of Company, adoption and approval of this Agreement
and approval of the Merger (each, a "Stockholders' Meeting") to be held as
promptly as practicable (within 45 days, if practicable, to the extent permitted
by applicable law and the regulations of the NYSE and Nasdaq) after the
declaration of effectiveness of the Registration Statement. Each of Parent and
Company will use reasonable best efforts to hold their respective Stockholders'
Meetings on the same date. Subject to Section 6.5(d), each of Parent and Company
will use all reasonable efforts to solicit from its respective stockholders
proxies in favor of, in the case of Parent, the Parent Stock Issuance, and, in
the case of the Company, the adoption and approval of this Agreement and the
approval of the Merger, and will take all other action necessary or advisable to
secure the vote or consent of their respective stockholders required by the
rules of NYSE, NASDAQ or the DGCL, as applicable, to obtain such approvals.
Notwithstanding anything to the contrary contained in this Agreement, Parent or
Company, as the case may be, may adjourn or postpone its Stockholders' Meeting
to the extent necessary to ensure that any necessary supplement or amendment to
the Prospectus/Proxy Statement is provided to its respective stockholders in
advance of a vote on the Parent Stock Issuance or the Merger and this Agreement,
as the case may be, or, if as of the time for which the Stockholders' Meeting is
originally scheduled (as set forth in the Prospectus/Proxy Statement) there are
insufficient Shares or insufficient shares of 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 Stockholders'

                                      -27-

Meeting. Each of Parent and Company shall ensure that its respective
Stockholders' Meeting is called, noticed, convened, held and conducted, and that
all proxies solicited by it in connection with the Stockholders' Meeting are
solicited in compliance with the DGCL, its certificate of incorporation and
bylaws, the rules of the NYSE and NASDAQ and all other Laws, as applicable.

         (b) Board Recommendation. Except to the extent expressly permitted by
Section 6.5(d): (i) the Board of Directors of each of Parent and Company shall
recommend that the respective stockholders of Parent and Company vote in favor
of, in the case of Parent, the Parent Stock Issuance, and, in the case of
Company, adoption and approval of this Agreement and approval of the Merger, at
their respective Stockholders' Meetings, (ii) the Prospectus/Proxy Statement
shall include a statement to the effect that the Board of Directors of Parent
has recommended that Parent's stockholders vote in favor of the Parent Stock
Issuance at the Parent Stockholders' Meeting and the Board of Directors of
Company has recommended that Company's stockholders vote in favor of adoption
and approval of this Agreement and approval of the Merger at the Stockholders'
Meeting of the Company; and (iii) neither the Board of Directors of Parent or
Company 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 Parent and Company vote in favor of, in the case of Parent, the
Parent Stock Issuance, and, in the case of Company, adoption and approval of
this Agreement and approval of the Merger.

         6.5 Acquisition Proposals.

         (a) No Solicitation. The Company agrees that neither it nor any of its
Subsidiaries nor any of the officers and directors of it or its Subsidiaries
shall, and that it shall use its reasonable best efforts to cause its and its
Subsidiaries' employees, agents and representatives (including any investment
banker, attorney or accountant retained by it or any of its Subsidiaries) not to
(and shall not authorize any of them to) directly or indirectly: (i) solicit,
initiate, encourage, knowingly facilitate or induce any inquiry with respect to,
or the making, submission or announcement of, any Acquisition Proposal (as
defined in Section 6.5(g)) with respect to itself, (ii) participate in any
discussions or negotiations regarding, or furnish to any Person any nonpublic
information with respect to, or take any other action to facilitate any
inquiries or the making of any proposal that constitutes or may reasonably be
expected to lead to, any Acquisition Proposal with respect to itself, (iii)
engage in discussions with any Person with respect to any Acquisition Proposal
with respect to itself, except as to the existence of these provisions, (iv)
approve, endorse or recommend any Acquisition Proposal with respect to itself,
or (v) enter into any letter of intent or similar document or any contract,
agreement or commitment contemplating or otherwise relating to any Acquisition
Proposal or transaction contemplated thereby with respect to itself. The Company
and its Subsidiaries will immediately cease any and all existing activities,
discussions or negotiations with any third parties conducted heretofore with
respect to any Acquisition Proposal.

         (b) Notification of Unsolicited Acquisition Proposals.

         (i) As promptly as practicable after receipt of any Acquisition
Proposal or any request for nonpublic information or inquiry which it reasonably
believes would

                                      -28-

lead to an Acquisition Proposal, the Company shall provide Parent with oral and
written notice of the material terms and conditions of such Acquisition
Proposal, request or inquiry, and the identity of the Person or group making any
such Acquisition Proposal, request or inquiry. The Company shall provide Parent
as promptly as practicable, oral and written notice setting forth all such
information as is reasonably necessary to keep Parent informed in all material
respects and on a current basis of any changes in the proposed material terms
and conditions or the status of any such Acquisition Proposal, request or
inquiry.

         (ii) The Company shall provide Parent with forty-eight (48) hours prior
notice (or such lesser prior notice as it 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 Acquisition Proposal.

         (c) Superior Offers. Notwithstanding anything to the contrary contained
in Section 6.5(a), in the event that the Company receives an unsolicited, bona
fide written Acquisition Proposal with respect to itself from a third party that
its Board of Directors has in good faith concluded (following consultation with
its outside legal counsel and its financial advisor), is, or is reasonably
likely to result in, a Superior Offer (as defined in Section 6.5(g)), it may
then take the following actions (but only if and to the extent that its Board of
Directors concludes in good faith, following consultation with its outside legal
counsel, that the failure to do so is required in order to prevent such Board of
Directors from breaching its fiduciary obligations under applicable law):

             (i) Furnish nonpublic information to the third party making such
Acquisition Proposal, provided that (A) (1) concurrently with furnishing any
such nonpublic information to such party, it gives Parent written notice of its
intention to furnish nonpublic information and (2) it receives from the third
party an executed confidentiality agreement containing customary limitations on
the use and disclosure of all nonpublic written and oral information furnished
to such third party on its behalf, the terms of which are at least as
restrictive as the terms contained in the Confidentiality Agreement (as defined
in Section 6.8) and (B) contemporaneously with furnishing any such nonpublic
information to such third party, it furnishes such nonpublic information to
Parent (to the extent such nonpublic information has not been previously so
furnished); and

             (ii) Engage in negotiations with the third party with respect to
the Acquisition Proposal, provided that concurrently with entering into
negotiations with such third party, it gives Parent written notice of its
intention to enter into negotiations with such third party.

         (d) Changes of Recommendation. In response to the receipt of a Superior
Offer, the Board of Directors of the Company may withhold, withdraw, amend or
modify its recommendation in favor of this Agreement and the Merger and may
indicate that it is doing so because it has received a Superior Offer (and, to
the extent required in order to comply with such Board of Directors' fiduciary
duties under applicable law, may endorse or recommend such Superior Offer) and,
in the case of the Company's receipt of a Superior Offer that is a tender or
exchange offer made directly to its stockholders, recommend that its
stockholders accept the tender or exchange offer (any of the foregoing actions,
whether by the Board of Directors of the

                                      -29-

Company or a committee thereof, a "Change of Recommendation"), if all of the
following conditions in clauses (i) through (iv) are met:

             (i) The Stockholders' Meeting of the Company has not occurred;

             (ii) A Superior Offer with respect to the Company has been made and
has not been withdrawn and its Board of Directors has concluded in good faith,
after consultation with its outside legal counsel, that, in light of such
Superior Offer, the Board of Directors is required to effect a Change of
Recommendation prevent a breach of its fiduciary obligations under applicable
law;

             (iii) The Company shall have (A) provided Parent written notice
which shall state expressly (1) that it has received a Superior Offer, (2) the
material terms and conditions of the Superior Offer and the identity of the
Person or group making the Superior Offer, and (3) that it intends to effect a
Change of Recommendation and the manner in which it intends to do so, (B)
provided to Parent a copy of all written materials and information delivered or
made available to the Person or group making the Superior Offer in connection
with such Superior Offer and not previously provided to Parent, and (C)
considered any counterproposal to the Superior Offer that Parent may make during
the five-day period after Parent's receipt of the written notice referred to in
clause (A) (no Change of Recommendation being permissible hereunder prior to the
end of such five-day period) and (D) determined in the good faith judgment of
its Board of Directors (following consultation with its outside legal counsel
and its financial advisor), that such counterproposal is less favorable, from a
financial point of view, to the Company's stockholders (in their capacities as
stockholders) than the Superior Offer.

             (iv) It shall not have breached in any material respect any of the
provisions set forth in Section 6.4 or this Section 6.5.

         (e) Continuing Obligation to Call, Hold and Convene Stockholders'
Meeting; No Other Vote. Notwithstanding anything to the contrary contained in
this Agreement, the obligation of the Company to call, give notice of, convene
and hold its Stockholders' Meeting shall not be limited or otherwise affected by
the commencement, disclosure, announcement or submission to it of any
Acquisition Proposal with respect to it, or by any Change of Recommendation. The
Company shall not call a meeting of its stockholders to consider, or submit to
the vote of its stockholders any Acquisition Proposal, or solicit (or attempt to
solicit) written consents of stockholders with respect to any Acquisition
Proposal or set any record date with respect to any such stockholders meeting or
consent solicitation. Nothing in this Section 6.5 shall (i) permit the Company
to terminate this Agreement or (ii) permit the Company to enter into any
agreement with respect to an Acquisition Proposal during the term of this
Agreement (it being agreed that during the term of this Agreement, the Company
shall not enter into any agreement with any Person that provides for or in any
way facilitates an Acquisition Proposal, other than a confidentiality agreement
compliant with Section 6.5(c)(i)).

         (f) Compliance with Tender Offer Rules. Nothing contained in this
Agreement shall prohibit the Company or its Board of Directors from taking and
disclosing to its stockholders a position contemplated by Rules 14d-9 and
14e-2(a) promulgated under the Exchange Act; provided that the content of any
such disclosure thereunder shall be subject to the terms of this

                                      -30-

Agreement. Without limiting the foregoing proviso, the Company shall not effect
a Change of Recommendation unless specifically permitted pursuant to the terms
of Section 6.5(d).

         (g) Certain Definitions. For purposes of this Agreement, the following
terms shall have the following meanings:

             (i) "Acquisition Proposal" shall mean any offer or proposal
relating to any transaction (other than the transaction contemplated by this
Agreement) or series of related transactions involving: (A) any purchase from
the Company or acquisition by any Person or "group" (as defined under Section
13(d) of the Exchange Act and the rules and regulations thereunder) of more than
a fifteen percent (15%) interest in the total outstanding voting securities of
the Company or any of its Subsidiaries or any tender offer or exchange offer
that if consummated would result in any Person or group beneficially owning
fifteen percent (15%) or more of the total outstanding voting securities of the
Company or any of its Subsidiaries or any merger, consolidation, business
combination or similar transaction involving the Company or any of its
Subsidiaries, (B) any sale, lease (other than in the ordinary course of
business), exchange, transfer, license (other than in the ordinary course of
business), acquisition or disposition of more than fifteen percent (15%) of the
assets of the Company (including its Subsidiaries taken as a whole), or (C) any
liquidation or dissolution of the Company; and

             (ii) "Superior Offer" shall mean an unsolicited, bona fide written
offer made by a third party to acquire, directly or indirectly, pursuant to a
tender offer, exchange offer, merger, consolidation or other business
combination, or asset purchase, all or substantially all of the assets of the
Company or a majority of the total outstanding voting securities of the Company
and as a result of which the stockholders of the Company immediately preceding
such transaction would hold less than fifty percent (50%) of the equity
interests in the surviving or resulting entity of such transaction or any direct
or indirect parent or subsidiary thereof, on terms that the Board of Directors
of the Company has in good faith concluded (following consultation with its
outside legal counsel and its financial adviser), to be more favorable, from a
financial point of view, to the Company's stockholders (in their capacities as
stockholders) than the terms of the Merger (or any counterproposal referred to
in Section 6.5(d)(iii)(C)) and is reasonably capable of being consummated.

         6.6 Filings; Other Actions; Notification.

         (a) The Company and Parent shall cooperate with each other and use (and
shall cause their respective Subsidiaries to use) its reasonable best efforts to
take or cause to be taken all actions, and do or cause to be done all things,
necessary, proper or advisable under this Agreement and applicable Laws to
consummate and make effective the Merger and the other transactions contemplated
by this Agreement as soon as practicable, including preparing and filing as
promptly as practicable all documentation to effect all necessary applications,
notices, petitions, filings and other documents and to obtain as promptly as
practicable all permits, consents, approvals and authorizations necessary or
advisable to be obtained from any third party and/or any Governmental Entity in
order to consummate the Merger or any of the other transactions contemplated by
this Agreement, including, without limitation: (i) the filing of Notification
and Report Forms with the United States Federal Trade Commission and the

                                      -31-

European Commission as required by Council Regulation No. 4064/89 of the
European Community, as amended (the "EC Merger Regulation") and (iii) filings
under any other comparable pre-merger notification laws of any applicable
jurisdiction; provided, however, that nothing in this Section 6.6 shall require,
or be construed to require, Parent (x) to proffer to, or agree to, sell or hold
separate and agree to sell, before or after the Effective Time, any material
assets, businesses, or interest in any material assets or businesses of Parent,
the Company or any of their respective Affiliates (or to consent to any sale, or
agreement to sell, by the Company of any of its material assets or businesses)
or (y) to agree to any material changes or restrictions in the operations of any
such assets or businesses, if, in the case of (x) or (y), such action or
agreement would be reasonably likely to have a material adverse effect on the
benefits reasonably expected to be derived by Parent and its Subsidiaries (on a
combined basis with the Company and its Subsidiaries) as a result of the
transactions contemplated hereby. Subject to applicable Laws relating to the
exchange of information, Parent and the Company shall have the right to review
in advance, and to the extent practicable each will consult the other on, all
the information relating to Parent or the Company, as the case may be, and any
of their respective Subsidiaries, that appear in any filing made with, or
written materials submitted to, any third party and/or any Governmental Entity
in connection with the Merger and the other transactions contemplated by this
Agreement. In exercising the foregoing right, each of the Company and Parent
shall act reasonably and as promptly as practicable.

         (b) The Company and Parent each shall, upon request by the other,
furnish the other with all information concerning itself, its Subsidiaries,
directors, officers and stockholders and such other matters as may be reasonably
necessary or advisable in connection with the Prospectus/Proxy Statement, the
Registration Statement, or any other statement, filing, notice or application
made by or on behalf of Parent, the Company or any of their respective
Subsidiaries to any third party and/or any Governmental Entity in connection
with the Merger and the transactions contemplated by this Agreement.

         (c) The Company and Parent each shall keep the other apprised of the
status of matters relating to completion of the transactions contemplated
hereby, including promptly furnishing the other with copies of notices or other
communications received by Parent or the Company, as the case may be, or by any

Entity with respect to the Merger and the other transactions contemplated by
this Agreement. The Company and Parent each shall give prompt notice to the
other upon becoming aware of: (i) any change that has had, or is reasonably
likely to have, a Material Adverse Effect on it; (ii) the occurrence or
nonoccurrence of any event the occurrence or nonoccurrence of which would
reasonably be likely to cause any representation or warranty of such party
contained in this Agreement to be untrue or inaccurate such that the condition
set forth in Section 7.2(a) or Section 7.3(a), as applicable, would not be
satisfied as of the date of such event or as of the Closing Date; (iii) any
material failure of the Company or Parent, as the case may be, to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder; or (iv) the occurrence or nonoccurrence of any event the
occurrence or nonoccurrence of which would reasonably be likely to cause any
condition to the obligations of any party to effect the transactions
contemplated hereby not to be satisfied; provided, however, that the delivery of
any notice pursuant to this Section 6.6(c) shall not cure such breach or
noncompliance or limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

                                      -32-

         (d) The Company shall, upon request by Parent, furnish Parent a list of
all material actions with respect to the Company's material Intellectual
Property Rights that are required to be taken by the Company within 180 days of
such request, including the payment of any registration, maintenance, renewal or
annuity fees and taxes or the filing of any documents, applications or
certificates for the purposes of maintaining, perfecting or preserving or
renewing such material Intellectual Property Rights

         6.7 Taxation.

         (a) Subject to Section 6.5, neither Parent nor the Company nor any of
their affiliates shall take or cause to be taken any action, whether before or
at the Effective Time, that would disqualify the Merger as a "reorganization"
pursuant to Section 368 of the Code.

         (b) Neither Parent nor the Company nor any of their respective
Affiliates shall take or cause to be taken any action, whether before or at the
Effective Time, that would cause Parent, the Company or any of their respective
Affiliates to be unable to make the representations necessary for counsel to
render the tax opinions referred to in Section 7.2(d)(ii).

         6.8 Access. Upon reasonable notice, and except as may otherwise be
required by applicable Law, each of the Company and Parent shall (and shall
cause its Subsidiaries to) afford the other's officers, employees, counsel,
accountants and other authorized representatives ("Representatives") access,
during normal business hours throughout the period prior to the Effective Time,
to its properties, books, contracts and records and, during such period, each
shall (and shall cause its Subsidiaries to) furnish promptly to the other all
information concerning its business, properties, results of operations and
personnel as may reasonably be requested to carry out the purposes of this
Agreement (including, without limitation, access to such personnel and records
of the Company or its Representatives as may be necessary to enable counsel to
deliver the opinions referred to in Section 7.2(d)), provided that no
investigation pursuant to this Section shall affect or be deemed to modify any
representation or warranty made by the Company, Parent or Merger Sub and
provided, further, that the foregoing shall not require the Company or Parent to
permit any inspection, or to disclose any information, that in the reasonable
judgment of the Company or Parent, as the case may be, would result in the
disclosure of any trade secrets of third parties or violate any of its
obligations with respect to confidentiality if the Company or Parent, as the
case may be, shall have used reasonable efforts to obtain the consent of such
third party to such inspection or disclosure. All requests for information made
pursuant to this Section shall be directed to an executive officer of the
Company or Parent, as the case may be, or such Person as may be designated by
either of its officers. The parties will hold any such information which is
nonpublic in confidence pursuant to the terms of the confidentiality agreement,
dated March 2, 2002, between the Company and Parent (the "Confidentiality
Agreement"). Nothing in this Section 6.8 will modify or alter the provisions of
the Confidentiality Agreement.

         6.9 Affiliates. Parent will give stop transfer instructions to its
transfer agent with respect to any Parent Common Stock received pursuant to the
Merger by any stockholder of the Company who may reasonably be deemed to be an
affiliate of the Company for purposes of Rule 145 promulgated under the
Securities Act and there will placed on the certificates

                                      -33-

representing such Parent Common Stock, or any substitution therefor, a legend
stating in substance that the shares are issued in a transaction to which Rule
145 promulgated under the Securities Act applies and may only be transferred (i)
in conformity with Rule 145 or (ii) in accordance with a written opinion of
counsel, reasonably acceptable to Parent, in form and substance, that such
transfer is exempt from registration under the Securities Act. Parent shall not
be required to maintain the effectiveness of the Registration Statement or any
other registration statement under the Securities Act for the purposes of resale
of Parent Common Stock by such affiliates received in the Merger, except as
provided in Section 6.17.

         6.10 NYSE Listing and Nasdaq De-quotation. Parent shall use its best
efforts to cause the shares of Parent Common Stock to be issued in the Merger to
be approved for listing on the NYSE subject to official notice of issuance,
prior to the Closing Date. The Company shall use its best efforts to cause the
Shares to be de-quoted from Nasdaq and de-registered under the Exchange Act as
soon as practicable following the Effective Time.

         6.11 Publicity. The initial press release concerning the Merger shall
be a joint press release and thereafter (except with respect to any press
release or public announcement relating to a Change of Recommendation) the
Company and Parent shall consult with each other prior to issuing any press
releases or otherwise making public announcements with respect to the Merger and
the other transactions contemplated by this Agreement and prior to making any
filings with any third party and/or any Governmental Entity (including any
national securities exchange) with respect thereto, except as may be required by
law or by obligations pursuant to any listing agreement with or rules of any
national securities exchange. Nothing contained in this Agreement shall prohibit
the Company or Parent from publicly disclosing this Agreement (including filing
this Agreement as an exhibit to a Report), or from making such public disclosure
as, in the good faith judgment of its Board of Directors (after consultation
with counsel), is required under applicable law, provided, that the Company may
not disclose a Change of Recommendation except as permitted by Section 6.5(d).

         6.12 Equity Awards and Employee Benefits.

         (a) Assumption of Stock Options. At the Effective Time, each then
outstanding Company Option, whether or not exercisable at the Effective Time and
regardless of the respective exercise (or base) prices thereof, will be assumed
by Parent. Each Company Option so assumed by Parent under this Agreement will
continue to have, and be subject to, the same terms and conditions set forth in
the applicable Company Option (including any applicable stock option agreement
or other document evidencing such Company Option) immediately prior to the
Effective Time (including any repurchase rights or vesting provisions), except
that (i) each Company Option will 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 number of shares of Parent Common Stock and (ii) the per share exercise
price for the shares of Parent Common Stock issuable upon exercise of such
assumed Company Option will 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. Each assumed

                                      -34-

Company Option shall be vested immediately following the Effective Time as to
the same percentage of the total number of shares subject thereto as it was
vested as to immediately prior to the Effective Time, except to the extent such
Company Option by its terms in effect prior to the date hereof provides for
acceleration of vesting. As soon as reasonably practicable, Parent will issue to
each Person who holds an assumed Company Option a document evidencing the
foregoing assumption of such Company Option by Parent, which shall not be
conditioned upon (or require in order that it be effective) the execution of any
document by such holder of an assumed Company Option, or the taking or any other
such action by such holder.

         (b) Incentive Stock Options. The conversion of Company Options provided
for in Section 6.12(a), with respect to any options which are intended to be
"incentive stock options" (as defined in Section 422 of the Code) shall be
effective in a manner consistent with Section 424(a) of the Code.

         (c) Termination of Company's Employee Stock Purchase Plan. The Company
shall, prior to the Effective Time, take all actions necessary pursuant to the
terms of the Company's 1995 Employee Stock Purchase Plan (the "1995 Plan") in
order to accelerate the Purchase Date for any outstanding Offering Period under
the 1995 Plan such that a new Purchase Date for all then outstanding Offering
Periods under the 1995 Plan shall occur on the day prior to the Effective Time
(the "New Purchase Date") and shares must be purchased by the participants in
the 1995 Plan under the 1995 Plan prior to the Effective Time. All outstanding
Offering Periods under the 1995 Plan shall expire immediately following such New
Purchase Date and the 1995 Plan shall terminate immediately prior to the
Effective Time. Capitalized terms in this Section and not otherwise defined in
this Agreement shall have the meanings ascribed to them in the Company's 1995
Plan.

         (d) Form S-8. Parent agrees to file a registration statement on Form
S-8 for the shares of Parent Common Stock issuable with respect to assumed
Company Options to the extent Form S-8 is available by no later than five (5)
business days after the Effective Time and, for so long as any of such options
or other rights remain outstanding, Parent shall (i) maintain the effectiveness
of such registration statement thereafter, and (ii) administer such options or
other rights in accordance with Rule 16b-3 under the Exchange Act.

         (e) Treatment of Welfare Plans.

             (i) All benefits accrued under the Compensation and Benefit Plans
of the Company or its Subsidiaries prior to the Effective Time shall be paid
from such Compensation and Benefit Plans in accordance with their terms.

             (ii) Following the Effective Time, Parent shall continue to provide
to individuals who are employed by the Company and its Subsidiaries as of the
Effective Time who remain employed with Parent or any Subsidiary of Parent
("Affected Employees"), for so long as such Affected Employees remain employed
by Parent or any Subsidiary of Parent, employee benefits (i) pursuant to the
Company's or its Subsidiaries' employee benefit plans, programs, policies and
arrangements, or (ii) pursuant to employee benefit plans, programs, policies or
arrangements maintained by Parent or any Subsidiary of Parent for its own
employees.

                                      -35-

             (iii) Parent will, or will cause the Surviving Corporation to, give
Affected Employees full credit for purposes of eligibility, vesting and benefit
accrual under any employee benefit plans or arrangements maintained by Parent or
any Subsidiary of Parent for such Affected Employees' service with the Company
or any Subsidiary of the Company to the same extent recognized by the Company
immediately prior to the Effective Time.

             (iv) Parent will, or will cause the Surviving Corporation to, (i)
waive all limitations as to preexisting conditions, exclusions and waiting
periods with respect to participation and coverage requirements applicable to
the Affected Employees under any welfare benefit plans that such employees may
be eligible to participate in after the Effective Time, other than limitations
or waiting periods that are already in effect with respect to such employees and
that have not been satisfied as of the Effective Time under any welfare plan
maintained for the Affected Employees immediately prior to the Effective Time,
and (ii) provide each Affected Employee with credit for any co-payments and
deductibles paid prior to the Effective Time in satisfying any applicable
deductible or out-of-pocket requirements under any welfare plans that such
employees are eligible to participate in after the Effective Time.

         6.13 Expenses. The Surviving Corporation shall pay all charges and
expenses, including those of the Exchange Agent, in connection with the
transactions contemplated in Article IV, and Parent shall reimburse the
Surviving Corporation for such charges and expenses. Except as otherwise
provided in Section 8.5(b), whether or not the Merger is consummated, all costs
and expenses incurred in connection with this Agreement and the Merger and the
other transactions contemplated by this Agreement shall be paid by the party
incurring such expense, except that expenses incurred in connection with
printing and mailing the Prospectus/Proxy Statement shall be shared equally by
the Company and Parent.

         6.14 Indemnification; Directors' and Officers' Insurance.

         (a) From and after the Effective Time, Parent agrees that it will
indemnify, defend and hold harmless each present and former director and officer
of the Company (when acting in such capacity) determined as of the Effective
Time (the "Indemnified Parties" and each an "Indemnified Party"), against any
costs or expenses (including but not limited to reasonable attorneys' fees),
judgments, fines, losses, claims, damages or liabilities (collectively, "Costs")
incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of matters existing or occurring at or prior to the Effective Time, whether
asserted or claimed prior to, at or after the Effective Time, to the fullest
extent that the Company would have been permitted under the DGCL and the
Company's certificate of incorporation, bylaws and other agreements in effect on
the date hereof to indemnify such Indemnified Party (and Parent shall also
advance expenses as incurred to the fullest extent permitted under applicable
law provided the Indemnified Party to whom expenses are advanced provides an
undertaking to repay such advances if it is ultimately determined that such
expenses can not be reimbursed or indemnified under applicable law to the extent
such undertaking is required by applicable law).

         (b) Any Indemnified Party wishing to claim indemnification under
paragraph (a) of this Section 6.14, upon learning of any such claim, action,
suit, proceeding or investigation, shall promptly notify Parent thereof. In the
event of any such claim, action, suit, proceeding or

                                      -36-

investigation (whether arising before or after the Effective Time), (i) Parent
or the Surviving Corporation shall have the right to assume the defense thereof
with legal counsel reasonably acceptable to such Indemnified Party and Parent
shall not be liable to such Indemnified Party for any legal expenses of other
counsel or any other expenses subsequently incurred by such Indemnified Party in
connection with the defense thereof (ii) the Indemnified Party will cooperate in
the defense of any such matter and (iii) Parent shall not be liable for any
settlement effected without its prior written consent (which will not be
unreasonably withheld or delayed); and provided, further, that Parent shall not
have any obligation hereunder to any Indemnified Party if and when a court of
competent jurisdiction shall ultimately determine, and such determination shall
have become final, that the indemnification of such Indemnified Party in the
manner contemplated hereby is prohibited by applicable law.

         (c) For a period of six years after the Effective Time, Parent will
cause the Surviving Corporation to use its reasonable best efforts to cause to
be maintained directors' and officers' liability insurance covering those
persons who are covered by the Company's directors' and officers' liability
insurance policy as of the date hereof on terms comparable to those applicable
to the current directors and officers of the Company for a period of six (6)
years; provided, however, that in no event will the Surviving Corporation be
required to expend in excess of one hundred seventy-five percent (175%) of the
annual premium currently paid by the Company for such coverage (and to the
extent the annual premium would exceed one hundred seventy-five percent (175%)
of the annual premium currently paid by the Company for such coverage, the
Surviving Corporation shall use its reasonable best efforts to cause to be
maintained the maximum amount of coverage as is available for such one hundred
seventy-five percent (175%) of such annual premium).

         (d) The provisions of this Section 6.14 are intended to be for the
benefit of, and shall be enforceable by, each of the Indemnified Parties and
their heirs and estates. Nothing in this Section 6.14 shall limit in any way any
other rights to indemnification that any current or former director or officer
of the Company may have by virtue of the certificate of incorporation or bylaws
of the Company, by contract or otherwise.

         6.15 Other Actions by the Company and Parent.

         (a) Rights. Prior to the Effective Time, the boards of directors of the
Company and Parent shall take all necessary action to ensure that the
representations and warranties in Section 5.1(p) are at all times true, accurate
and complete.

         (b) Takeover Statute. If any Takeover Statute is or may become
applicable to the Merger or the other transactions contemplated by this
Agreement, each of Parent and the Company and its Board of Directors shall grant
such approvals and take such lawful actions as are necessary so that such
transactions may be consummated as promptly as practicable on the terms
contemplated by this Agreement or by the Merger and otherwise act to eliminate
or minimize the effects of such statute or regulation on such transactions.

         6.16 Section 16 Matters. Prior to the Effective Time, Parent and the
Company shall take all such steps as may be required (to the extent permitted
under applicable law) to cause any dispositions of Shares or acquisitions of
Parent Common Stock resulting from the transactions

                                      -37-

contemplated by Article I of 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.

         6.17 Convertible Notes. Prior to the Effective Time, the Company and
Parent shall take all actions necessary to provide that on and after the
Effective Time the Convertible Notes will be convertible only into Parent Common
Stock (taking into account adjustment for the Exchange Ratio), subject to any
holder's right to hold Convertible Notes through maturity. As of the Effective
Time, (a) the Company and Parent shall execute and deliver to the trustee under
the Indenture governing the Convertible Notes (the "Indenture") a supplemental
indenture that satisfies the requirements of Section 4.11 of the Indenture (the
"Supplemental Indenture"), and (b) Parent either will assume or cause the
Surviving Corporation to comply with all of the Company's obligations under the
Registration Rights Agreement relating to the Convertible Notes (the
"Registration Rights Agreement"), except that all obligations under the
Registration Rights Agreement to register Shares shall become obligations to
register the appropriate number of shares (after adjustment for the Exchange
Ratio) of Parent Common Stock. Parent shall file with the SEC a registration
statement under the Securities Act that registers the resale of the Parent
Common Stock issuable upon conversion of the Convertible Notes on a continual
basis under Rule 415 under the Securities Act (the "Note Registration
Statement") and shall use its reasonable efforts to cause such Note Registration
Statement to be declared effective by the SEC under the Securities Act as soon
as practicable after the Effective Time.

their respective Subsidiaries from, any Governmental Entity (collectively,
"Governmental Consents") in connection with the execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby by the
Company, Parent and Merger Sub shall have been made or obtained (as the case may
be), except where the failure to so make or

                                      -38-

obtain has not had, and is not reasonably likely to have, a Material Adverse
Effect on the Company or Parent or a material adverse effect on the benefits
reasonably expected to be derived by Parent and its Subsidiaries (on a combined
basis with the Company and its Subsidiaries) as a result of the transactions
contemplated herein.

         (c) No Order. No Governmental Entity of competent jurisdiction shall
have enacted, issued, promulgated, enforced or entered any statute, rule,

temporary, preliminary or permanent) which (i) is in effect and (ii) has the
effect of making the Merger illegal or otherwise prohibiting consummation of the
Merger.

         (d) No Governmental Restriction. There shall not be any pending or
overtly threatened suit, action or proceeding asserted by any Governmental
Entity (i) challenging or seeking to restrain or prohibit the consummation of
the Merger or any of the other transactions contemplated by this Agreement, the
effect of which restraint or prohibition if obtained would cause the condition
set forth in Section 7.1(c) to not be satisfied or (ii) seeking to require
Parent or the Company or any of their respective Subsidiaries to take any action
contemplated by the proviso set forth in Section 6.6(a).

         (e) Registration Statement. The Registration Statement shall have

Date, and Parent shall have received a certificate signed on behalf of the
Company by the chief executive officer and chief financial officer of the
Company to such effect; provided, however, that notwithstanding anything herein
to the contrary, the conditions set forth in this Section 7.2(a) shall be deemed
to have been satisfied even if such representations or warranties are not so
true and correct unless the failure of such representations or warranties to be
so true and correct, individually or in the aggregate, has had, or is reasonably
likely to have, a Material Adverse Effect on the Company or is reasonably likely
to materially adversely affect the ability of the Company to effect the Merger
in accordance with this Agreement.

         (b) Performance of Obligations of the Company. The Company shall have
performed in all material respects all material obligations required to be
performed by it under this Agreement at or prior to the Closing Date, and Parent

         (c) Consents Under Certain Agreements. The Company shall have obtained
the consent or approval of each Person whose consent or approval shall be
required under any Contract to which the Company or any of its Subsidiaries is a

Adverse Effect on the Company or is not reasonably likely to materially
adversely affect the ability of the Company to consummate the transactions
contemplated by this Agreement.

         (d) Tax Opinions.

             (i) Parent shall have received the opinion of Pillsbury Winthrop
LLP, counsel to Parent, dated the Closing Date, to the effect that the Merger

opinions may be delivered by Fenwick & West LLP. The parties to this Agreement
agree to make such reasonable representations as may be requested by such

opinions, such counsel may rely on such representations.

             (ii) Parent shall have received the opinion of Pillsbury Winthrop

of the Code to apply to the transactions addressed in the Original Ruling, and

Subsidiaries. Parent shall have received the resignation of each officer of the
Company and each of its Subsidiaries from whom Parent has requested a
resignation five business days prior to Closing (it being understood that any
such resignation shall not affect the rights, if any, of such officer under any
change of control or other severance arrangement disclosed to Parent prior to
the date hereof).

         (f) Comfort Letters. Parent shall have received the "comfort" letters
referred to in Section 6.2(c).

                                      -40-

likely to materially adversely affect the ability of Parent to effect the Merger
in accordance with this Agreement.

or inaccuracy is given by Parent to the Company.

         8.5 Effect of Termination and Abandonment.

         (a) Any proper termination of this Agreement under Section 8.2, 8.3 or
8.4 above will be effective immediately upon the delivery of written notice of
termination by the terminating party to the other parties hereto. In the event
of termination of this Agreement pursuant to this Article VIII, this Agreement
(other than as set forth in Section 9.1) shall become void and of no effect with
no liability of any party hereto (or any of its directors, officers, employees,
agents, legal and financial advisors or other representatives); provided,
however, except as otherwise provided herein, no such termination shall relieve
any party hereto of any liability or damages resulting from any material or
willful breach of this Agreement.

         (b) In the event that (i) a bona fide Acquisition Proposal shall have
been made to the Company and made known to stockholders of the Company generally
or has been made directly to stockholders of the Company generally or any Person
shall have publicly announced an intention (whether or not conditional) to make
a bona fide Acquisition Proposal regarding the

                                      -43-

Company and such Acquisition Proposal or announced intention shall not have been
withdrawn prior to the Stockholders' Meeting of the Company and thereafter this
Agreement is terminated by either Parent or the Company, as applicable, pursuant
to Section 8.2(b) or, following a willful and material breach by the Company of
this Agreement, Section 8.4(b), or (ii) this Agreement is terminated by Parent
pursuant to Section 8.4(a), then the Company shall promptly, but in no event
later than two days after the date of such termination, pay Parent a termination
fee of twenty-five million dollars ($25,000,000) (the "Termination Fee") payable
by wire transfer of same-day funds; provided, however, that no Termination Fee
shall be payable to Parent pursuant to clause (i) of this paragraph, unless
within twelve (12) months of such termination the Company enters into an
agreement providing for an Acquisition of the Company (as defined below) and an
Acquisition of the Company is consummated within eighteen (18) months of such
termination, in which event payment of such Termination Fee shall be made
promptly, but in no event later than two (2) business days after consummation of
such Acquisition of the Company. The term "Acquisition of the Company" for
purposes of this Section 8.5(b) means any of the following transactions
involving the Company: (i) a merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving the
Company pursuant to which the stockholders of the Company immediately preceding
such transaction hold less than fifty percent (50%) of the aggregate equity
interests in the surviving or resulting entity of such transaction or any direct
or indirect parent thereof, (ii) a sale or other disposition by the Company of
assets representing in excess of fifty percent (50%) of the aggregate fair
market value of the Company's business immediately prior to such sale, or (iii)
the acquisition by any Person or group (including by way of a tender offer or an
exchange offer or issuance by the party or such Person or group), directly or
indirectly, of beneficial ownership or a right to acquire beneficial ownership
of shares representing in excess of fifty percent (50%) of the voting power of
the then-outstanding shares of capital stock of the Company. The Company
acknowledges that the agreements contained in this Section 8.5(b) are an
integral part of the transactions contemplated by this Agreement, and that,
without these agreements, Parent and Merger Sub would not enter into this
Agreement; accordingly, if the Company fails to pay promptly the amount due
pursuant to this Section 8.5(b), and, in order to obtain such payment, Parent or
Merger Sub commences a suit which results in a judgment against the Company for
the fee set forth in this Section 8.5(b), the Company shall pay to Parent or
Merger Sub its costs and expenses (including attorneys' fees) in connection with
such suit, together with interest on the amount of the fee at the prime lending
rate of Citibank, N.A. in effect on the date such payment was required to be
made.
