its respective stockholders to consummate the business combination transaction
provided for herein in which Merger Sub will merge with and into the Company

                      CONVERSION AND EXCHANGE OF SECURITIES

            Section 2.1 Conversion of Capital Stock.

            At the Effective Time, by virtue of the Merger and without any
action on the part of the Company, Parent, Merger Sub or any holder of any
shares of common stock, par value $0.01 per share, of the Company ("Company
Common Stock") or any capital stock of Merger Sub:

                  (a) Company Common Stock. Subject to this Article II, each
share of Company Common Stock issued and outstanding immediately prior to the
Effective Time (other than shares to be cancelled in accordance with Section
2.1(b) and Dissenting Shares referred to in Section 2.3), together with each
associated "Right" (as defined in the Rights Agreement, dated as of August 3,
2000, between the Company and Fleet National Bank, as rights agent, as amended
through the date hereof (the "Company Rights Agreement")), shall be converted
into the right to receive (i) 0.552 (the "Exchange Ratio") shares of common
stock, par value $0.01 per share ("Parent Common Stock") of Parent (the "Stock
Merger Consideration") and (ii) $3.50 in cash without interest (the "Cash Merger
Consideration" and, together with the Stock Merger Consideration, the "Merger
Consideration"), payable upon the surrender of the Certificates (as defined in
Section 2.2(b)). From and after the Effective Time, all such shares of Company
Common Stock, shall no longer be outstanding and shall automatically be
cancelled and retired and shall cease to exist, and each holder of a Certificate
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive the Merger Consideration pursuant to this
Section 2.1(a), any cash in lieu of fractional shares payable pursuant to
Section 2.2(d) and any dividends or other distributions to which such holder is
entitled to pursuant to Section 2.2(c). Notwithstanding the foregoing, the
Exchange Ratio shall be appropriately adjusted to reflect fully the effect of
any stock split, reverse split, reclassification, stock dividend (including any
dividend or distribution of securities convertible into Parent Common Stock or
Company Common Stock), reorganization, recapitalization, consolidation, exchange
or other like change with respect to Parent Common Stock or Company Common Stock
occurring (or having a record date) after the date of this Agreement and prior
to the Effective Time.

                                       3


                                                                  EXECUTION COPY

                  (b) Cancellation of Treasury Stock and Parent-Owned Stock. All
shares of Company Common Stock, together with each associated Right, that are
(i) held by the Company as treasury shares or (ii) owned by Parent or any wholly
owned Subsidiary (as defined below) of Parent, in each case immediately prior to
the Effective Time, shall be cancelled and retired and shall cease to exist, and
no securities of Parent or other consideration shall be delivered in exchange
therefor. As used in this Agreement, the word "Subsidiary" means, with respect
to any party, any corporation or other organization, whether incorporated or
unincorporated, of which (A) such party or any other Subsidiary of such party is
a general partner, manager or managing member, (B) such party or any Subsidiary
of such party owns in excess of a majority of the outstanding equity or voting
securities or interests or (C) such party or any Subsidiary of such party has
the right to elect at least a majority of the board of directors or others
performing similar functions with respect to such corporation or other
organization.

                  (c) Capital Stock of Merger Sub. Each share of common stock,
par value $0.01 per share, of Merger Sub ("Merger Sub Common Stock") issued and
outstanding immediately prior to the Effective Time shall be converted into and
become one fully paid and nonassessable share of common stock, par value $0.01
per share, of the Surviving Corporation.

                  (d) Stock Options; Deferred Phantom Stock. Outstanding options
to purchase shares of Company Common Stock and outstanding deferral accounts
under the 1995 Director Plan (each, a "Phantom Unit Account") shall be treated
in the manner set forth in Section 6.10.

            Section 2.2 Exchange of Certificates.

                  (a) Exchange Agent. Prior to the Closing Date, Parent shall
designate a bank or trust company to act as Exchange Agent hereunder (the
"Exchange Agent"). As soon as practicable after the Effective Time, Parent shall
deposit with or for the account of the Exchange Agent, for the benefit of the
holders of Company Common Stock, stock certificates representing the shares of
Parent Common Stock and an amount of cash sufficient to deliver to the holders
of Company Common Stock (other than the Dissenting Shares) the aggregate Merger
Consideration pursuant to Section 2.1(a), any cash in lieu of fractional shares
payable pursuant to Section 2.2(d) and any dividends or other distributions to
which such holders are entitled pursuant to Section 2.2(c) (such certificates
for shares of Parent Common Stock and cash, together with cash in lieu of
fractional shares and dividends or other distributions being hereinafter
referred to as the "Exchange Fund") deliverable pursuant to Section 2.1 in
exchange for outstanding shares of Company Common Stock.

                  (b) Exchange Procedures. As soon as practicable after the
Effective Time, Parent will instruct the Exchange Agent to mail to each holder
of record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding shares

                                       4


                                                                  EXECUTION COPY

of Company Common Stock (the "Certificates") that were converted pursuant to
Section 2.1(a) into the right to receive the Merger Consideration (i) a letter
of transmittal (which 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 shall be in such form and have such other
provisions as Parent may reasonably specify that are not inconsistent with the
terms of this Agreement), and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration. Upon
surrender of a Certificate for cancellation to the Exchange Agent together with
such letter of transmittal, duly executed, and such other customary documents as
may be required pursuant to such instructions, the holder of such Certificate
shall be entitled to receive (A) certificates evidencing the Stock Merger
Consideration which such holder has the right to receive pursuant to Section
2.1(a) in respect of the shares of Company Common Stock formerly evidenced by
such Certificate, (B) the Cash Merger Consideration which such holder has the
right to receive pursuant to Section 2.1(a) in respect of the shares of Company
Common Stock formerly evidenced by such Certificate, (C) cash in lieu of any
fractional shares of Parent Common Stock to which such holder is entitled
pursuant to Section 2.2(d), and (D) any dividends or other distributions to
which such holder is entitled pursuant to Section 2.2(c), after giving effect to
any tax withholdings required by applicable Law, and the Certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of shares of Company Common Stock which is not registered in the
transfer records of the Company as of the Effective Time, a certificate
representing the proper number of shares of Parent Common Stock may be issued to
a transferee if the Certificate evidencing such Company Common Stock is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer pursuant to this Section 2.2(b) and by
evidence that any applicable stock transfer taxes have been paid. Until so
surrendered, each outstanding Certificate that, prior to the Effective Time,
represented shares of Company Common Stock will be deemed, from and after the
Effective Time, for all corporate purposes, to represent only the right to
receive upon surrender the Merger Consideration and any cash in lieu of any
fractional shares of Parent Common Stock payable pursuant to Section 2.2(d), in
accordance with the terms of this Agreement.

                  (c) Distributions with Respect to Unexchanged Shares of Parent
Common Stock. No dividends or other distributions declared or made after the
Effective Time with respect to Parent Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Parent Common Stock represented thereby, and no cash
payment in lieu of fractional shares shall be paid to any such holder pursuant
to Section 2.2(d), unless and until the holder of such Certificate shall
surrender such Certificate. Subject to the effect of escheat, tax or other
applicable Laws, following surrender of any such Certificate, there shall be
paid to the holder of the certificates representing whole shares of Parent
Common Stock issued in exchange therefor, in addition to the Merger
Consideration deliverable therefore pursuant to Section 2.1, without interest,
(A) 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 2.2(d) and (B)
at the appropriate payment date, the amount of dividends or other distributions,
with

                                       5


                                                                  EXECUTION COPY

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.

                  (d) No Fractional Shares. No certificate or scrip representing
fractional shares of Parent Common Stock shall be issued upon the surrender for
exchange of Certificates, and such fractional share interests shall not entitle
the owner thereof to vote or to any other rights of a stockholder of Parent.
Notwithstanding any other provision of this Agreement, each holder of shares of
Company Common Stock converted pursuant to the Merger who would otherwise have
been entitled to receive a fraction of a share of Parent Common Stock (after
taking into account all Certificates delivered by such holder and the aggregate
number of shares of Company Common Stock represented thereby) shall receive, in
lieu thereof, cash (without interest) in an amount equal to such fractional part
of a share of Parent Common Stock multiplied by the last reported sales price of
Parent Common Stock at the end of regular trading hours on the New York Stock
Exchange (the "NYSE") on the Closing Date (the "Parent Closing Price").

                  (e) Transfers of Ownership. 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 will be a
condition to the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise be in proper form for transfer and that the
person requesting such exchange will have paid to Parent or any agent designated
by it any transfer or other taxes required by reason of the issuance of a
certificate for shares of Parent Common Stock in any name other than that of the
registered holder of the Certificate surrendered, or will have established to
the satisfaction of Parent or any agent designated by it that such tax has been
paid or is not payable.

                  (f) Termination of Exchange Fund; No Liability. At any time
following the first anniversary of the Effective Time, Parent shall be entitled
to require the Exchange Agent to deliver to Parent any portion of the Exchange
Fund not disbursed to holders of Certificates, and thereafter such holders shall
be entitled to look only to Parent (subject to abandoned property, escheat or
other similar Law) with respect to the Merger Consideration to which such
holders are entitled pursuant to Section 2.1(a), any cash in lieu of fractional
shares payable to such holders pursuant to Section 2.2(d) and any dividends or
other distributions to which such holders are entitled pursuant to Section
2.2(c), upon due surrender of their Certificates, without any interest thereon.
Neither Parent, Merger Sub nor the Company shall be liable to any holder of
Company Common Stock or Parent Common Stock, as the case may be, for such shares
(or dividends or distributions with respect thereto) delivered to a public
official pursuant to any applicable abandoned property, escheat or other similar
Law following the passage of time specified therein.

                  (g) Withholding Rights. Parent, the Surviving Corporation or
the Exchange Agent shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Agreement to any person who was
a holder of Company Common Stock immediately prior to the Effective Time such
amounts as Parent or the Exchange Agent is required to deduct and withhold with
respect to the making of such payment under the Code, or any provision of state,
local or foreign tax Law. To the extent that amounts are

                                       6


                                                                  EXECUTION COPY

so withheld by Parent, the Surviving Corporation or the Exchange Agent, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the shares of Parent Common Stock in respect of which
such deduction and withholding was made by Parent, the Surviving Corporation or
the Exchange Agent.

                  (h) No Further Ownership Rights in Company Stock. At the
Effective Time, the stock transfer books of the Company shall be closed and
thereafter there shall be no further registration of transfers on the stock
transfer books of the Company or the Surviving Corporation of the shares of
Company Common Stock which were outstanding immediately prior to such time. If,
after such time, Certificates are presented to the Surviving Corporation for any
reason, they shall be cancelled and exchanged as provided in this Article II.

                  (i) Lost, Stolen or Destroyed Certificates. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of Parent
Common Stock as may be required pursuant to Section 2.1(a) as well as the other
Merger Consideration as provided in this Article II and any dividends or other
distributions to which the holders thereof are entitled pursuant to Section
2.2(c); provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificates to deliver an agreement of indemnification in form
satisfactory to Parent, or a bond in such sum as Parent may reasonably direct as
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the Certificates alleged to have been lost, stolen or
destroyed.

            Section 2.3 Dissenting Stockholders.

            Notwithstanding anything in this Agreement to the contrary, shares
of Company Common Stock that are outstanding immediately prior to the Effective
Time and held by a holder thereof who properly exercises and perfects appraisal
rights for such shares in accordance with Section 262 of the DGCL (the
"Dissenting Shares") will be paid for by the Surviving Corporation in accordance
with Section 262 of the DGCL; provided, however, that if any such holder shall
fail to perfect or otherwise shall waive, withdraw or lose the right to
appraisal and payment under the DGCL, the right of such holder to such appraisal
of its shares of Company Common Stock shall cease and such shares of Company
Common Stock shall be deemed converted as of the Effective Time into the right
to receive the Merger Consideration to which any such holder is entitled
pursuant to Section 2.1(a), any cash in lieu of fractional shares payable to any
such holder pursuant to Section 2.2(d) and any dividends or other distributions
to which any such holder is entitled pursuant to Section 2.2(c). The Company
shall give Parent (a) prompt notice of any written demands for appraisal
received by the Company, withdrawals of such demands, and any other related
instruments served pursuant to Section 262 of the DGCL and received by the
Company and (b) the opportunity to direct all negotiations and proceedings with
respect to demands for appraisals under the DGCL. The Company shall not, except
with prior written consent of Parent, (i) voluntarily make any payment with
respect to any demands for

                                       7


                                                                  EXECUTION COPY

appraisal for Dissenting Shares, (ii) offer to settle, or settle, any such
demands, (iii) waive any failure to timely deliver a written demand for
appraisal in accordance with the DGCL, or (iv) agree to do any of the foregoing.

            Section 2.4 Alternative Merger Consideration.

            Notwithstanding anything in this Agreement to the contrary, in the
event that the Tax Opinion condition set forth in Section 7.1(g) would not
otherwise be satisfied with respect to the Merger, the amount of the aggregate
Cash Merger Consideration shall be reduced to the minimum extent necessary and,
subject to the following sentence, the aggregate Stock Merger Consideration
shall be increased to the minimum extent necessary, to enable the Tax Opinion or
Tax Opinions, as the case may be, to be rendered. For purposes of determining
the number of additional shares of Parent Common Stock to be issued to
stockholders of the Company pursuant to the preceding sentence, the Exchange
Ratio shall be increased by an amount equal to the quotient obtained by dividing
(A) the amount of the reduction in the Cash Merger Consideration by (B) the
Parent Closing Price, provided, however, absent a change in law, solely for
purposes of determining whether counsel may render the Tax Opinion or Tax
Opinions, the value of the shares of Parent Common Stock shall be determined by
using the average of the high and low trading price of the Parent Common Stock
on the NYSE on the Closing Date.

            Section 2.5 Material Adverse Effect.

                  (a) The term "Company Material Adverse Effect" means any
change, effect or circumstance that (i) is materially adverse to the business,
operation, properties or condition (financial or otherwise), of the Company and
its Subsidiaries, taken as a whole, or (ii) materially adversely affects the
consummation of the transactions contemplated hereby; provided, however, that in
no event shall any of the following, either alone or in combination, be deemed
to constitute, nor shall any of the following be taken into account in
determining whether there has been or will or could be, a Company Material
Adverse Effect: (A) any changes resulting from or arising out of general market,
economic or political conditions (including any changes arising out of acts of
terrorism, or war, weather conditions or other force majeure events), provided
that such changes do not have a substantially disproportionate impact on the
Company and its Subsidiaries, taken as a whole, (B) any changes resulting from
or arising out of general market, economic or political conditions in the
industries in which the Company or any of its Subsidiaries conduct business
(including any changes arising out of acts of terrorism, or war, weather

have a substantially disproportionate impact on the Company and its
Subsidiaries, taken as a whole, (C) any changes resulting from or arising out of
actions taken pursuant to (and required by) this Agreement or at the request of
Parent or the failure to take any actions due to restrictions set forth in this
Agreement, (D) any changes in the price or trading volume of the Company's
stock, in and of itself, (E) any failure by the Company to meet published
revenue or earnings projections, in and of itself, (F) any changes or effects
arising out of or resulting

                                                                  EXECUTION COPY

from any legal claims or other proceedings made by any of the Company's
stockholders arising out of or related to this Agreement, the Merger or any
other transactions contemplated hereby and (G) any changes arising out of or
resulting from any delay with respect to the receipt by the Company or any of
its Subsidiaries of pending regulatory approvals relating to its proposed
product offerings of no longer than three months after the date that the Company
has informed Parent it expects to obtain such pending regulatory approvals
(provided that at all times during such period, such approvals are still pending
and can be reasonably expected to be obtained within such period).

                  (b) The term "Parent Material Adverse Effect" means any
change, effect or circumstance that (i) is materially adverse to the business,
operation, properties or condition (financial or otherwise), of Parent and its
Subsidiaries, taken as a whole, or (ii) materially adversely affects the
consummation of the transactions contemplated hereby; provided, however, that in
no event shall any of the following, either alone or in combination, be deemed
to constitute, nor shall any of the following be taken into account in
determining whether there has been or will or could be, a Parent Material
Adverse Effect: (A) any changes resulting from or arising out of general market,
economic or political conditions (including any changes arising out of acts of
terrorism, or war, weather conditions or other force majeure events), provided
that such changes do not have a substantially disproportionate impact on Parent
and its Subsidiaries, taken as a whole, (B) any changes resulting from or
arising out of general market, economic or political conditions in the
industries in which Parent or any of its Subsidiaries conduct business
(including any changes arising out of acts of terrorism, or war, weather
conditions or other force majeure events), provided that such changes do not
have a substantially disproportionate impact on Parent and its Subsidiaries,
taken as a whole, (C) any changes resulting from or arising out of actions taken
pursuant to (and required by) this Agreement or at the request of the Company or
the failure to take any actions due to restrictions set forth in this Agreement,
(D) any changes in the price or trading volume of Parent's stock, in and of
itself, (E) any changes or effects arising out of or resulting from any legal

publicly traded company held for investment by the Company and comprising less
than one percent of the outstanding stock of such company.

            Section 3.2 Certificate of Incorporation and Bylaws.

required to be disclosed by the Company in the reports that it files or submits
to the SEC under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the rules and forms of the SEC and
that such information is accumulated and communicated to the Company's
management as appropriate to allow timely decisions regarding required
disclosure and to make the certifications of the chief executive officer and
chief financial officer of the Company required under the Exchange Act with
respect to such reports. The Company maintains internal accounting controls

in accordance with management's general or specific authorizations, (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets, (iii) access to assets is permitted only in

"ERISA Affiliate" means any entity which is, or at any applicable time was, a
member of (A) a controlled group of corporations (as defined in Section 414(b)
of the Code), (B) a group of trades or businesses under common control (as
defined in Section 414(c) of the Code) or (C) an affiliated service group (as
defined under Section 414(m) of the Code or the regulations under Section 414(o)
of the Code), any of which includes or included the Company or Parent, as
applicable, or a Subsidiary.

                  (b) With respect to each Company Employee Plan, the Company
has made available to Parent complete and accurate copies of (i) such Company
Employee Plan (or a written summary of any unwritten plan) together with all
amendments, (ii) in the case of any plan for which Forms 5500 are required to be
filed, the most recent annual report (Form 5500) with schedules attached, (iii)
in the case of any plan that is intended to be qualified under Section 401(a) of

                                                                  EXECUTION COPY

similar material employee communications relating to employee benefits matters,
(vi) all personnel, payroll and employment manuals and policies, and (vii) the
most recent financial statements for each Company Employee Plan that is funded.

                  (c) Each Company Employee Plan has been administered in all
material respects in accordance with ERISA, the Code and all other applicable
Laws and the regulations thereunder and in accordance with its terms and each of
the Company, the Company's Subsidiaries and their respective ERISA Affiliates
have in all material respects met their obligations with respect to each Company
Employee Plan and have timely made (or timely will make) all required
contributions thereto. All filings and reports as to each Company Employee Plan
required to have been submitted to the Internal Revenue Service or to the United
States Department of Labor have been timely submitted. With respect to the
Company Employee Plans, no event has occurred, and, to the Company's Knowledge,
there exists no condition or set of circumstances in connection with which the
Company, Parent or any of their respective Subsidiaries or any plan participant
could be subject to any material liability (including penalties or taxes) under
ERISA, the Code or any other applicable Law, nor will the negotiation or
consummation of the transactions contemplated by this Agreement give rise to any
such material liability.

                  (d) With respect to the Company Employee Plans, there are no
material benefit obligations for which contributions have not been made or
properly accrued and there are no benefit obligations which have not been
accounted for by reserves, or otherwise properly footnoted in accordance with
the requirements of GAAP, on the financial statements of the Company. The assets
of each Company Employee Plan which is funded are reported at their fair market
value on the books and records of such Employee Benefit Plan.

                  (e) No Company Employee Plan (other than the Company Stock
Plans) has assets that include securities issued by the Company, any of the
Company's Subsidiaries or any of their ERISA Affiliates.

                  (f) All the Company Employee Plans that are intended to be
qualified under Section 401(a) of the Code (each, a "Qualified Plan") have
received determination, opinion or advisory letters from the Internal Revenue
Service to the effect that such Company Employee Plans are qualified and the
plans and trusts related thereto are exempt from federal income taxes under
Sections 401(a) and 501(a), respectively, of the Code, or the Company has
remaining a period of time under applicable U.S. Department of the Treasury
regulations or Internal Revenue Service pronouncements in which to apply for
such a letter and to make any amendments necessary to obtain a favorable
determination as to the qualified status of each such Qualified Plan. To the
Company's Knowledge, no such determination, opinion or advisory letter has been
revoked and revocation has not been threatened, and no such Employee Benefit
Plan has been amended or operated since the date of its most recent
determination letter or application therefor in any respect, and no act or
omission has occurred, that would reasonably be expected to adversely affect its
qualification or materially increase its cost. There has been no termination,
partial termination or discontinuance of contributions to any Qualified Plan

                                       20


                                                                  EXECUTION COPY

that will result in material liability to the Company. Each Company Employee
Plan which is required to satisfy Section 401(k)(3) or Section 401(m)(2) of the
Code has been tested for compliance with, and satisfies in all material respects
the requirements of Section 401(k)(3) and Section 401(m)(2) of the Code, as the
case may be, for each plan year ending prior to the Closing Date for which
testing is required to be completed.

                  (g) Neither the Company, any of the Company's Subsidiaries nor
any of their respective ERISA Affiliates has (i) ever maintained a Company
Employee Plan which was ever subject to Section 412 of the Code or Title IV of
ERISA or (ii) ever been obligated to contribute to a "multiemployer plan" (as
defined in Section 4001(a)(3) of ERISA). No Company Employee Plan is funded by,
associated with or related to a "voluntary employees' beneficiary association"
within the meaning of Section 501(c)(9) of the Code.

                  (h) To the extent permitted by applicable Law, each Company
Employee Plan (other than the Company Stock Plans or an employment, severance,
change in control or similar agreement with an individual) is amendable and
terminable unilaterally by the Company and any of the Company's Subsidiaries
party thereto or covered thereby at any time without material liability to the
Company or any of its Subsidiaries as a result thereof, other than for benefits
accrued as of the date of such amendment or termination and routine
administrative costs.

                  (i) Other than as required under Section 601 et seq. of ERISA,
none of the Company Employee Plans promises or provides health or other welfare
benefits (excluding normal claims for benefits under the Company's group life
insurance, accidental death and dismemberment insurance and disability plans and
policies) or coverage to any person following retirement or other termination of
employment. Section 3.13(i) of the Company Disclosure Schedule lists each
Company Employee Plan which provides benefits after termination of employment
(other than medical benefits required to be continued under Section 4980B of the
Code and part 6 of Subtitle B of Title I of ERISA) and normal claims for
benefits under the Company's group life insurance, accidental death and
dismemberment insurance and disability plans and policies) and the present value
of benefits accrued under each such Company Employee Plan are fully funded,
fully covered by insurance or reflected on the Company Balance Sheet in
accordance with GAAP.

                  (j) There is no action, suit, proceeding, claim, arbitration,
audit or investigation pending or, to the Company's Knowledge, threatened, with
respect to any Company Employee Plan, other than claims for benefits in the
ordinary course. No Company Employee Plan is or within the last three calendar
years has been the subject of, or has received notice that it is the subject of,
examination by a government agency or a participant in a government sponsored
amnesty, voluntary compliance or similar program.

                  (k) To the Company's Knowledge, each individual who has
received compensation for the performance of services on behalf of the Company,
any of the Company's Subsidiaries or any of their respective ERISA Affiliates
has been properly classified as an employee or independent contractor in
accordance with applicable Law.

                                       21


                                                                  EXECUTION COPY

                  (l) Each Company Employee Plan maintained or covering
employees outside the United States, and the books and records thereof, is in
material compliance with all applicable Laws of each applicable jurisdiction.
Section 3.13(l) of the Company Disclosure Schedule lists each country in which
the Company or any of its Subsidiaries or affiliates has operations and the
number of employees in each such country.

                  (m) Section 3.13(m) of the Company Disclosure Schedule sets
forth a true, complete and correct list of (i) all employment agreements with
employees of the Company or any of its Subsidiaries; (ii) all employees or
former employees of the Company or any of its Subsidiaries who have executed a
non-competition agreement with the Company or any of its Subsidiaries; (iii) all
severance agreements, programs and policies of the Company or any of its
Subsidiaries with or relating to its employees, excluding programs and policies
required to be maintained by Law; and (iv) all plans, programs, agreements and
other arrangements of the Company or any of its Subsidiaries pursuant to which
payments (or acceleration of benefits or vesting of options or lapse of
repurchase rights) may be required, or may become payable directly or indirectly
as a result of or in connection with, the negotiation or consummation of the
transactions contemplated by, or the execution of, this Agreement. True,
complete and correct copies of each of the foregoing agreements to which any
employee of the Company is a party have been made available to Parent.

                  (n) All contributions required to be made with respect to any
Company Employee Plan on or prior to the Effective Time have been or will be
timely made or are reflected on the Company Balance Sheet. There are no pending,
threatened or reasonably anticipated claims by or on behalf of any Plan, by any
employee or beneficiary covered under any such Company Employee Plan, or
otherwise involving any such Plan (other than routine claims for benefits).

                  (o) The negotiation or consummation of the transactions
contemplated by this Agreement will not, either alone or in combination with
another event, (i) entitle any current or former employee or officer of the
Company or any Subsidiary of the Company to severance pay, or any other payment
from the Company or any of its Subsidiaries or (ii) accelerate the time of
payment or vesting, a lapse of repurchase rights or increase the amount of
compensation due any such employee or officer. There is no Company Employee Plan
or other contract, agreement, plan or arrangement that, individually or
collectively, could give rise to the payment of any amount that would not be
deductible pursuant to Sections 280G (determined without regard to Section
280G(b)(4) of the Code) or 162(m) of the Code.

            Section 3.14 Labor Matters.

                  (a) The Company and each of its Subsidiaries are in compliance
in all material respects with all applicable Laws respecting employment and
employment practices, including, without limitation, all Laws respecting terms

and layoffs, affirmative action, workers' compensation, labor relations,
employee leave issues and unemployment insurance.

                  (b) There are no personnel manuals, handbooks, policies, rules
or procedures applicable to employees of the Company and/or any of its
Subsidiaries, other than those set forth in Section 3.14(b) of the Company
Disclosure Schedule, true and complete copies or written summaries of which have
heretofore been provided to Parent.

                  (c) There are no actions, suits, claims, grievances,
investigations, or other proceedings pending or, to the Company's Knowledge,
threatened, between (i) the Company or any of its Subsidiaries (and/or any of
their current or former officers, directors, employees, or representatives, in
their capacities as such) and (ii) any of their respective current or former
employees, consultants or independent contractors, or any applicant for
employment or classes of the foregoing, or any Governmental Entity, which
actions, suits, claims, grievances, investigations, or other proceedings have or
would reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect.

                  (d) The Company and each of its Subsidiaries has good labor
relations, and the Company, each of its Subsidiaries, and their respective
employees, agents or representatives have not committed any unfair labor
practice as defined in the National Labor Relations Act. Neither the Company nor
any of its Subsidiaries is a party to, bound by or subject to (and none of the
Company's and/or any of its Subsidiaries' properties or assets is bound by or
subject to) any labor agreement, collective bargaining agreement, work rules or
practices, or any other labor-related agreements or arrangements with any labor
union, labor organization, trade union or works council. There are no labor
agreements, collective bargaining agreements, work rules or practices, or any
other labor-related agreements or arrangements that pertain to any of the
employees of the Company and/or any of its Subsidiaries, and no employees of the
Company and/or any of its Subsidiaries are represented by any labor union, labor
organization, trade union or works council with respect to their employment with
the Company and/or any of its Subsidiaries.

                  (e) To the Company's Knowledge, there are no current labor
union organizing activities with respect to any employees of the Company and/or
any of its Subsidiaries, and no labor union, labor organization, trade union,
works council, or group of employees of the Company and/or any of its
Subsidiaries has made a pending demand for recognition or certification, and
there are no representation or certification proceedings or petitions seeking a
representation proceeding presently pending or threatened in writing to be
brought or filed with the National Labor Relations Board or any other labor
relations tribunal or authority. To the Company's Knowledge there are no labor
disputes, strikes, slowdowns, work stoppages, lockouts, or threats thereof,
against or affecting the Company or any of its Subsidiaries.

                  (f) No employee of the Company or any of its Subsidiaries (i)
to the Company's Knowledge is in violation of any term of any patent disclosure
agreement, non-competition agreement, or any restrictive covenant to a former
employer relating to the right

                                       23


                                                                  EXECUTION COPY

of any such employee to be employed by the Company or any of its Subsidiaries
because of the nature of the business conducted or presently proposed to be
conducted by the Company or any of its Subsidiaries or relating to the use of

key employee or group of key employees, has given notice as of the date of this
Agreement to the Company or any of its Subsidiaries that such employee or any
employee in a group of key employees intends to terminate his or her employment
with the Company or any of its Subsidiaries.

                  (g) The Company and each of its Subsidiaries are and have been
in compliance with all notice and other requirements under the Worker Adjustment
and Retraining Notification Act of 1988, as amended (the "WARN Act"), and any
similar foreign, state or local Law relating to plant closings and layoffs.
Neither the Company nor any of its Subsidiaries is currently engaged in any
layoffs or employment terminations sufficient in number to trigger application
of the WARN Act or any similar state, local or foreign Law. Section 3.14(g) of
the Company Disclosure Schedule contains a true and complete list of the names
and the sites of employment or facilities of those individuals who suffered an
"employment loss" (as defined in the WARN Act) at any site of employment or
facility of the Company or any of its Subsidiaries during the 90-day period
prior to the date of this Agreement. Section 3.14(g) of the Company Disclosure
Schedule shall be updated immediately prior to the Closing with respect to the
90-day period prior to the Closing.

                  (h) The execution of this Agreement and the consummation of
the transactions contemplated by this Agreement will not result in any breach or
other violation of any collective bargaining agreement, employment agreement,
consulting agreement or any other labor-related agreement to which the Company
and/or any of its Subsidiaries is a party.

            Section 3.15 Properties; Encumbrances.

            Each of the Company and each of its Subsidiaries has good and valid
title to, or a valid leasehold interest in, all the properties and assets which
it purports to own or lease (real, tangible, personal and mixed), including all
the properties and assets reflected in the Company Balance Sheet (except for
personal property sold since the date of the Company Balance Sheet in the
ordinary course of business consistent with past practice). All properties and
assets reflected in the Company Balance Sheet are free and clear of all Liens,
except for Liens reflected on the Company Balance Sheet and Liens for current
taxes not yet due and other Liens that do not materially detract from the value
or impair the use of the property or assets subject thereto. Section 3.15 of the
Company Disclosure Schedule sets forth a true, complete and correct list of all
real property owned, leased, subleased or licensed by the Company and the
location of such premises. All material real property leases, licenses or other
occupancy agreements to which the Company or any of its Subsidiaries is a party
(collectively, the "Company Real Property Leases") are either filed as exhibits
to the Company SEC Reports or complete copies thereof have been delivered to or
made available to Parent. Section 3.15 of the Company Disclosure Schedule lists

the date of this Agreement, (i) all Company Real Property Leases are in full
force and effect (except as such enforceability may be subject to laws of
general application relating to bankruptcy, insolvency and the relief of debtors
and rules of law governing specific performance, injunctive relief or other
equitable remedies), (ii) there is no existing material breach or violation of
or default by the Company or any of its Subsidiaries under any of the Company
Real Property Leases, except such breaches, violations and defaults as have been
waived in writing, (iii) no event has occurred with respect to the Company or
any of its Subsidiaries which, with notice or lapse of time or both, would
constitute a material breach, violation or default of any of the Company Real
Property Leases, and (iv) to the Company's Knowledge, there are no breaches,
defaults or violations of any material obligations of the landlord under any
Company Real Property Lease.

            Section 3.16 Taxes.

                  (a) For purposes of this Agreement, "Tax" or "Taxes" shall
mean taxes, fees, assessments, liabilities, levies, duties, tariffs, imposts and
governmental impositions or charges of any kind in the nature of (or similar to)
taxes, payable to any federal, state, local or foreign taxing authority, or any
agency or subdivision thereof, including (i) income, franchise, profits, gross
receipts, ad valorem, net worth, value added, sales, use, service, real or
personal property, special assessments, capital stock, license, payroll,

statements with respect to Taxes required to be filed with a taxing authority,
domestic or foreign, including, consolidated, combined or unitary tax returns
and any amendments to any of the foregoing.

                  (b) The Company and each of its Subsidiaries have filed with
the appropriate taxing authorities all material Tax Returns required to be filed
by them, and all such Tax Returns were true, complete and correct in all
material respects. All Taxes required to be paid by the Company and each of its
Subsidiaries have been timely paid. There are no Tax Liens on any assets of the
Company or any Subsidiary thereof other than liens relating to Taxes not yet due
and payable. Neither the Company nor any of its Subsidiaries has granted any
outstanding waiver of any statute of limitations with respect to, or any
outstanding extension of a period for the assessment of, any Tax. The accruals
and reserves for Taxes (exclusive of any accruals for "deferred taxes" or
similar items that reflect timing differences between tax and financial
accounting principles) reflected in the Company Balance Sheet are adequate to
cover all Taxes accruable through the date thereof (including interest and
penalties, if any, thereon and Taxes being contested) in accordance with GAAP
applied on a consistent basis with the Company Balance Sheet. All liabilities
for Taxes attributable to the period commencing on the date following the date
of the

                                       25

                  (c) The Company and each of its Subsidiaries have timely
withheld with respect to its employees all federal and state Taxes required to
be withheld. Neither the Company nor any of its Subsidiaries has received any
notice of any Tax deficiency outstanding, proposed or assessed against the
Company or any of its Subsidiaries. Neither the Company nor any of its
Subsidiaries has received any written notice of any audit examination,
deficiency, refund litigation, proposed adjustment or matter in controversy with
respect to any Tax Return of the Company or any of its Subsidiaries. Neither the
Company nor any of its Subsidiaries is a party to or bound by any tax indemnity,
tax sharing or tax allocation agreements with any entity other than the Company
or any Company Subsidiary. Except for the group of which the Company and its
Subsidiaries are now currently members, neither the Company nor any of its
Subsidiaries has ever been a member of an affiliated group of corporations
within the meaning of Section 1504 of the Code. Neither the Company nor any of
its Subsidiaries is liable for the Taxes of any person under Treasury Regulation
1.1502-6 (or any similar provision of state, local or foreign Law) as a
transferee or successor, by contract or otherwise.

                  (d) To the extent requested by Parent, the Company made
available to Parent complete and correct copies of all income Tax Returns,
examination reports and statements of deficiencies assessed against or agreed to
by the Company or any of its Subsidiaries with respect to all taxable years for
which the statutes of limitation have not expired.

                  (e) Neither the Company nor any of its Subsidiaries has agreed

                  (g) Neither the Company nor any of its Subsidiaries has
constituted either a "distributing corporation" or a "controlled corporation"
(within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of
stock qualifying for tax-free treatment under Section 355 of the Code (A) in the
two years prior to the date of this Agreement or (B) in a distribution which
could otherwise constitute part of a "plan" or "series of related transactions"
(within the meaning of Section 355(e) of the Code) in connection with the
Merger.

                  (h) Neither the Company nor any of its Subsidiaries is a party
to, or has any commitment to become a party to, any tax shelter arrangement as
described in Internal Revenue Service final regulations (T.D. 9046).

            Except as disclosed in the Company SEC Reports, (a) the Company and

environment or mitigation of adverse effects thereon (collectively,
"Environmental Laws"), and including, but not limited to, compliance with any
Company Permits or other governmental authorizations or the terms and conditions
thereof; (b) neither the Company nor any of its Subsidiaries has received any

personal injuries, attorney's fees or penalties relating to (i) the presence, or
release into the environment, of any Materials of Environmental Concern at any
location owned or operated by the Company or its Subsidiaries, now or in the
past, or (ii) any violation, or alleged violation, of any Environmental Law
(collectively, "Environmental Claims"), except where such Environmental Claims
would not reasonably be expected to have a Company Material Adverse Effect or

operation of Law, except where such Environmental Claim, if made, would not have
a Company Material Adverse Effect or otherwise require disclosure in the Company
SEC Reports. The Company has provided to Parent and Merger Sub all assessments,
reports, data, results of investigations or audits, and other information that
is in the possession of or reasonably available to the Company regarding
environmental matters pertaining to or the environmental condition of the
business of the Company and its Subsidiaries, or the compliance (or

Entities that are material to the operation of their respective business as
currently conducted (collectively, the "Parent Permits"). The Parent Permits are
in full force and effect, have not been violated in any material respect and no
suspension, revocation or cancellation thereof has been threatened, and there is
no action, proceeding or investigation pending or, to Parent's Knowledge,
threatened, seeking the suspension, revocation or cancellation of any Parent
Permits. No Parent Permit shall cease to be effective as a result of the
consummation of the transactions contemplated by this Agreement, other than as
would not reasonably be expected to have a Parent Material Adverse Effect.

            Section 4.7 SEC Filings; Financial Statements.

                  (a) Parent has filed all forms, reports, schedules, statements
and other documents, including any exhibits thereto, required to be filed by
Parent since its inception with the SEC (collectively, the "Parent SEC
Reports"). The Parent SEC Reports, including all forms, reports and documents
filed by Parent with the SEC after the date hereof and prior to the Effective
Time, (i) were and, in the case of Parent SEC Reports filed after the date
hereof, will be, prepared in all material respects in accordance with the
applicable requirements of the Securities Act and the Exchange Act, as the case
may be, and the rules and regulations thereunder and (ii) did not at the time
they were filed (or if amended or superseded by a filing prior to the date of
this Agreement, then on the date of such filing) and, in the case of such forms,
reports and documents filed by Parent with the SEC after the date of this
Agreement, will not as of the time they are filed, contain any untrue statement
of a material fact or omit to state a material fact required to be stated in
such Parent SEC Reports or necessary in order to make the statements in such
Parent SEC Reports, in light of the circumstances under which they were made,
not misleading. None of the Subsidiaries of Parent is required to file any
forms, report, schedules or other documents with the SEC.

                  (b) Each of the consolidated financial statements (including,
in each case, any related notes and schedules) contained in the Parent SEC
Reports, including any Parent SEC Reports filed between the date of this
Agreement and the Closing, complied or will comply, as of its respective date,
in all material respects with all applicable accounting requirements and the
published rules and regulations of the SEC with respect thereto, was or will be
prepared in accordance with GAAP (except as may be indicated in the notes
thereto) applied on a consistent basis throughout the periods involved and
fairly presented in all material respects or will fairly present in all material
respects the consolidated financial position of Parent and its consolidated
Subsidiaries as of the respective dates thereof and the

                                       37


                                                                  EXECUTION COPY

consolidated results of the operations and cash flows of Parent and its
consolidated Subsidiaries for the periods indicated, except as otherwise
explained therein and except that any unaudited interim financial statements are
subject to normal and recurring year-end adjustments which have not been made
and are not expected to be material in amount, individually or in the aggregate.
The audited balance sheet of Parent contained in the Parent SEC Report on Form
10-K for the fiscal year ended December 31, 2003 is referred to herein as the
"Parent Balance Sheet."

                  (c) The chief executive officer and chief financial officer of
Parent have made all certifications required by, and would be able to make such
certifications as of the date hereof and as of the Closing Date as if required
to be made as of such dates pursuant to, Sections 302 and 906 of the
Sarbanes-Oxley Act and any related rules and regulations promulgated by the SEC
and the statements contained in any such certifications are complete and
correct, and Parent is otherwise in compliance with all applicable effective
provisions of the Sarbanes-Oxley Act and the applicable listing standards and
corporate governance rules of the NYSE.

            Section 4.8 Disclosure Controls and Procedures.

            Since December 31, 2003, Parent and each of its Subsidiaries has had
in place "disclosure controls and procedures" (as defined in Rules 13a-15(e) and
15d-15(e) promulgated under the Exchange Act) reasonably designed and maintained
to ensure that all information (both financial and non-financial) required to be
disclosed by Parent in the reports that it files or submits to the SEC under the
Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the rules and forms of the SEC and that such information is
accumulated and communicated to Parent's management as appropriate to allow
timely decisions regarding required disclosure and to make the certifications of
the chief executive officer and chief financial officer of Parent required under
the Exchange Act with respect to such reports. Parent maintains internal
accounting controls sufficient to provide reasonable assurances that (i)
transactions are executed in accordance with management's general or specific
authorizations, (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain accountability for assets, (iii) access to
assets is permitted only in accordance with management's general or specific
authorization, and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

            Section 4.9 Absence of Certain Changes or Events.

            From the date of the Parent Balance Sheet and except as disclosed in
the Parent SEC Reports through the date hereof, Parent has conducted its
business in the ordinary course of business consistent with past practice and,
since such date and through the date hereof, there has not occurred: (i) any
Parent Material Adverse Effect; (ii) any amendments to or changes in the Parent
Charter or Parent Bylaws; (iii) any material damage to, destruction or loss of
any asset of Parent or any of its Subsidiaries (whether or not covered by
insurance); (iv) any change by Parent in its accounting methods, principles or

                                       38


                                                                  EXECUTION COPY

practices; (v) any revaluation by Parent of any of its assets, including writing
down the value of inventory or writing off notes or accounts receivable other
than in the ordinary course of business consistent with past practice; (vi) any
sale of a material amount of assets (tangible or intangible) of Parent or any of
its Subsidiaries; or (vii) any recalls, field notifications, field corrections
or safety alerts with respect to products manufactured by or on behalf of Parent
or any of its Subsidiaries or (viii) any other action or event that would have
required the consent of the Company pursuant to Section 5.2 had such action or
event occurred after the date of this Agreement.

            Section 4.10 No Undisclosed Liabilities.

                  (a) Except as reflected in the Parent Balance Sheet, neither
Parent nor any of its Subsidiaries has any liabilities (absolute, accrued,
contingent or otherwise) which are required by GAAP to be set forth on a
consolidated balance sheet of Parent and its consolidated Subsidiaries or in the
notes thereto, other than (i) any liabilities and obligations incurred since the
date of the Parent Balance Sheet in the ordinary course of business consistent
with past practice, (ii) any liabilities or obligations incurred in connection
with the transactions contemplated by this Agreement and (iii) liabilities that,
individually or in the aggregate, have not had, and would not reasonably be
expected to have, a Parent Material Adverse Effect.

                  (b) Neither Parent nor any of its Subsidiaries is a party to,
or has any commitment to become a party to, any joint venture, partnership
agreement or any similar contract (including any contract relating to any
transaction, arrangement or relationship between or among Parent or any of its
Subsidiaries, on the one hand, and any unconsolidated affiliate, including any
structured finance, special purpose or limited purpose entity or person, on the
other hand) where the purpose or intended effect of such arrangement is to avoid
disclosure of any material transaction involving Parent or any of its
Subsidiaries in the Parent's consolidated financial statements.

            Section 4.11 Absence of Litigation; Investigations.

            Except as disclosed in the Parent SEC Reports prior to the date of
this Agreement, there are no claims, actions, suits, proceedings, governmental
investigations, inquiries or subpoenas (other than challenging or otherwise
arising from or relating to the Merger or any of the other transactions
contemplated by this Agreement), (a) pending against Parent or any of its
Subsidiaries, or any of their respective properties or assets, (b) to Parent's
Knowledge, threatened against Parent or any of its Subsidiaries, or any of their
respective properties or assets or (c) whether filed or threatened, that have
been settled or compromised by Parent or any of its Subsidiaries since June 29,
2002 and at the time of such settlement or compromise were material, which
claims, actions, suits, proceedings investigations, inquiries or subpoenas
referred to in clause (a) would reasonably be expected to have a Parent Material
Adverse Effect. Neither Parent nor any Subsidiaries of Parent is subject to any
outstanding order, writ, injunction or decree that would reasonably be

                                       39


                                                                  EXECUTION COPY

expected to be material or would reasonably be expected to prevent or delay the
consummation of the transactions contemplated by this Agreement. There has not
been nor are there currently any internal investigations or inquiries being
conducted by Parent, the Parent Board (or any committee thereof) or any third
party at the request of any of the foregoing concerning any financial,
accounting, tax, conflict of interest, self-dealing, fraudulent or deceptive
conduct or other misfeasance or malfeasance issues.

            Section 4.12 Agreements, Contracts and Commitments

                  (a) All of the Parent Material Contracts (as defined below)
that are required to be described in the Parent SEC Reports (or to be filed as
exhibits thereto) are so described or filed and are in full force and effect.
"Parent Material Contracts" shall mean any note, bond, mortgage, indenture,
guarantee, other evidence of indebtedness, lease, license, contract, agreement
or other instrument or obligation to which Parent or any of its Subsidiaries is
a party or by which any of them or any of their Assets are bound, and which
either (i) has a remaining term of more than one year from the date hereof and
(A) cannot be unilaterally terminated by Parent at any time, without material
penalty, within thirty (30) days of providing notice of termination, and (B)
involves the payment or receipt of money in excess of $7.5 million in any year,
(ii) involves the payment or receipt of money in excess of $10 million in any
year, or (iii) contains covenants limiting the freedom of Parent or any of its
Subsidiaries to sell any products or services of or to any other person, engage
in any line of business or compete with any person or operate at any location;
provided, however, that a Real Property Lease shall not be considered a Parent
Material Contract.

                  (b) As of the date of this Agreement, (i) there is no breach
or violation of or default by Parent or any of its Subsidiaries under any of the
Parent Material Contracts, except such breaches, violations and defaults as have
been waived, and (ii) no event has occurred with respect to Parent or any of its
Subsidiaries which, with notice or lapse of time or both, would constitute a
breach, violation or default, or give rise to a right of termination,
modification, cancellation, foreclosure, imposition of a Lien, prepayment or
acceleration under any of the Parent Material Contracts, which breach, violation
or default referred to in clauses (i) or (ii), would reasonably be expected to
have, individually or in the aggregate, a Parent Material Adverse Effect.

            Section 4.13 Employee Benefit Plans, Options and Employment
Agreements.

                  (a) Section 4.13(a) of the Parent Disclosure Schedule sets
forth a complete and accurate list of all Employee Benefit Plans maintained, or
contributed to by Parent, any of its Subsidiaries or any of their respective
ERISA Affiliates or to which Parent, any of its Subsidiaries or any of their
respective ERISA Affiliates is obligated to contribute, or under which any of
them has or may have any liability for premiums or benefits for the

                                       40


                                                                  EXECUTION COPY

benefit of employees located in the United States (collectively, the "Parent
Employee Plans").

                  (b) With respect to each Parent Employee Plan, Parent has made
available to the Company complete and accurate copies of (i) such Parent
Employee Plan (or a written summary of any unwritten plan) together with all
amendments, (ii) in the case of any plan for which Forms 5500 are required to be
filed, the most recent annual report (Form 5500) with schedules attached, (iii)
in the case of any plan that is intended to be qualified under Section 401(a) of
the Code, the most recent determination letter from the Internal Revenue
Service, (iv) each trust agreement, group annuity contract, administration and
similar material agreements, investment management or investment advisory
agreements, (v) the most recent summary plan descriptions and employee handbook,
or other similar material employee communications relating to employee benefits
matters, (vi) all personnel, payroll and employment manuals and policies, and
(vii) the most recent financial statements for each Parent Employee Plan that is
funded.

                  (c) Each Parent Employee Plan has been administered in all
material respects in accordance with ERISA, the Code and all other applicable
Laws and the regulations thereunder and materially in accordance with its terms
and each of Parent, its Subsidiaries and their respective ERISA Affiliates have
in all material respects met their obligations with respect to each Parent
Employee Plan and have timely made (or timely will make) all required
contributions thereto. All filings and reports as to each Parent Employee Plan
required to have been submitted to the Internal Revenue Service or to the United
States Department of Labor have been timely submitted. With respect to the
Parent Employee Plans, no event has occurred, and, to Parent's Knowledge, there
exists no condition or set of circumstances in connection with which Parent, its
Subsidiaries or any plan participant could be subject to any material liability
(including penalties or taxes) under ERISA, the Code or any other applicable
Law, nor will the negotiation or consummation of the transactions contemplated
by this Agreement give rise to any such material liability.

                  (d) With respect to the Parent Employee Plans, there are no
material benefit obligations for which contributions have not been made or
properly accrued and there are no benefit obligations which have not been
accounted for by reserves, or otherwise properly footnoted in accordance with
the requirements of GAAP, on the financial statements of Parent. The assets of
each Parent Employee Plan which is funded are reported at their fair market
value on the books and records of such Parent Employee Plan.

                  (e) No Parent Employee Plan has assets that include securities
issued by Parent, any of its Subsidiaries or any of their respective ERISA
Affiliates.

                  (f) All the Parent Employee Plans that are Qualified Plans
have received determination, opinion or advisory letters from the Internal
Revenue Service to the effect that such Parent Employee Plans are qualified and
the plans and trusts related thereto are exempt from federal income taxes under
Sections 401(a) and 501(a), respectively, of the Code, or Parent has remaining a
period of time under applicable U.S. Department of the Treasury regulations or
Internal Revenue Service pronouncements in which to apply for such

                                       41


                                                                  EXECUTION COPY

a letter and to make any amendments necessary to obtain a favorable
determination as to the qualified status of each such Qualified Plan. To
Parent's Knowledge, no such determination, opinion or advisory letter has been
revoked and revocation has not been threatened, and no such Parent Employee Plan
has been amended or operated since the date of its most recent determination
letter or application therefor in any respect, and no act or omission has
occurred, that would reasonably be expected to adversely affect its
qualification or materially increase its cost. There has been no termination,
partial termination or discontinuance of contributions to any Qualified Plan
that will result in material liability to Parent. Each Parent Employee Plan
which is required to satisfy Section 401(k)(3) or Section 401(m)(2) of the Code
has been tested for compliance with, and satisfies in all material respects the
requirements of Section 401(k)(3) and Section 401(m)(2) of the Code, as the case
may be, for each plan year ending prior to the Closing Date for which testing is
required to be completed.

                  (g) Neither Parent, any of its Subsidiaries nor any of their
respective ERISA Affiliates has (i) ever maintained a Parent Employee Plan which
was ever subject to Section 412 of the Code or Title IV of ERISA or (ii) ever
been obligated to contribute to a "multiemployer plan" (as defined in Section
4001(a)(3) of ERISA) that is subject to ERISA. No Parent Employee Plan is funded
by, associated with or related to a "voluntary employees' beneficiary
association" within the meaning of Section 501(c)(9) of the Code.

                  (h) To the extent permitted by applicable Law, each Parent
Employee Plan (other than the Parent Stock Plans or an employment, severance,
change in control or similar agreement with an individual) is amendable and
terminable unilaterally by Parent or one or more of its Subsidiaries party
thereto or covered thereby at any time without material liability to Parent or
any of its Subsidiaries as a result thereof, other than for benefits accrued as
of the date of such amendment or termination and routine administrative costs.

                  (i) Other than as required under Section 601 et seq. of ERISA,
none of the Parent Employee Plans promises or provides health or other welfare
benefits (excluding normal claims for benefits under the Parent's group life
insurance, accidental death and dismemberment insurance and disability plans and
policies) or coverage to any person following retirement or other termination of
employment.

                  (j) There is no action, suit, proceeding, claim, arbitration,
audit or investigation pending or, to Parent's Knowledge, threatened, with
respect to any Parent Employee Plan, other than claims for benefits in the
ordinary course. No Parent Employee Plan is or within the last two calendar
years has been the subject of, or has received notice that it is the subject of,
examination by a government agency or a participant in a government sponsored
amnesty, voluntary compliance or similar program.

                  (k) To Parent's Knowledge, each individual who has received
compensation for the performance of services on behalf of Parent, any of its
Subsidiaries or their respective ERISA Affiliates has been properly classified
as an employee or independent contractor in accordance with applicable Law.

                                       42


                                                                  EXECUTION COPY

                  (l) Except as would not reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect, with respect
to each Employee Benefit Plan maintained by Parent, any of its Subsidiaries or
any of their ERISA Affiliates that covers employees outside the United States,
and the books and records thereof, (i) such plan is in compliance with all
applicable Laws of each applicable jurisdiction; (ii) there is no action, suit,
proceeding, claim, arbitration, audit or investigation pending or, to Parent's
Knowledge, threatened, with respect to such plan, other than claims for benefits
in the ordinary course; (iii) all liabilities with respect to such plan are set
forth on a consolidated balance sheet of Parent and its Subsidiaries or in the
notes thereto in accordance with GAAP; and (iv) no such plan is or within the
last two calendar years has been the subject of, or has received notice that it
is the subject of, an examination by a government agency or a participant in a
government sponsored amnesty, voluntary compliance or similar program that has
given rise to or is reasonably expected to give rise to any liability.

                  (m) True, complete and correct copies of each of the following
agreements to which any employee of Parent is a party have been made available
to the Company: (i) all employment agreements with employees of Parent; (ii) all
employees or former employees of Parent who have executed a non-competition
agreement with Parent; (iii) all severance agreements, programs and policies of
Parent or any of its Subsidiaries with or relating to its employees, excluding
programs and policies required to be maintained by Law; and (iv) all plans,
programs, agreements and other arrangements of Parent or any of its Subsidiaries
pursuant to which payments (or acceleration of benefits or vesting of options or
lapse of repurchase rights) may be required upon, or may become payable directly
or indirectly as a result of or in connection with, the negotiation or
consummation of the transactions contemplated by, or the execution of, this
Agreement.

                  (n) All contributions required to be made with respect to any
Parent Employee Plan on or prior to the Effective Time have been or will be
timely made or are reflected on the Parent's Balance Sheet. There are no
pending, threatened or reasonably anticipated claims by or on behalf of any
Plan, by any employee or beneficiary covered under any such Parent Employee
Plan, or otherwise involving any such Plan (other than routine claims for
benefits).

                  (o) The negotiation or consummation of the transactions
contemplated by this Agreement will not, either alone or in combination with
another event, (i) entitle any current or former employee or officer of Parent
or any of its Subsidiaries to severance pay, or any other payment from Parent or
any of its Subsidiaries or (ii) accelerate the time of payment or vesting, cause
a lapse of repurchase rights or increase the amount of compensation due any such
employee or officer. There is no Parent Employee Plan or other contract,
agreement, plan or arrangement that, individually or collectively, could give
rise to the payment of any amount that would not be deductible pursuant to
Sections 280G (determined without regard to Section 280G(b)(4) of the Code) or
162(m) of the Code.

            Section 4.14 Labor Matters.

                                       43


                                                                  EXECUTION COPY

            (a) Parent and each of its Subsidiaries is in compliance in all
material respects with all applicable Laws respecting employment, employment
practices and occupational safety and health, terms and conditions of employment
and wages and hours, and is not engaged in any unfair labor practices; (b) to
Parent's Knowledge, there are no actions, suits, claims or grievances pending or
threatened, between Parent or any of its Subsidiaries and any of its employees,
consultants or independent contractors, which actions, suits, claims or
grievances have or would reasonably be expected to have a Parent Material
Adverse Effect; (c) neither Parent nor any of its Subsidiaries is a party to any
collective bargaining agreement or other labor union contract applicable to
persons employed by Parent in the United States, nor does Parent nor any of its
Subsidiaries know of any current activities or proceedings of any labor union to
organize any such employees; and (d) to Parent's Knowledge, there are no labor
disputes, strikes, slowdowns, work stoppages, lockouts, or threats thereof, by
or with respect to any employees of, or consultants or independent contractors
to, Parent or any of its Subsidiaries in the United States.

            Section 4.15 Properties; Encumbrances.

            Parent and each of its Subsidiaries has good and valid title to, or
a valid leasehold interest in, all the properties and assets which it purports
to own or lease (real, tangible, personal and mixed), including all the
properties and assets reflected in the Parent Balance Sheet (except for personal
property sold since the date of the Parent Balance Sheet in the ordinary course
of business consistent with past practice). All properties and assets reflected
in the Parent Balance Sheet are free and clear of all Liens, except for Liens
reflected on the Parent Balance Sheet and Liens for current taxes not yet due
and other Liens that do not materially detract from the value or impair the use
of the property or assets subject thereto. All material real property leases,
licenses or other occupancy agreements to which Parent or any of its
Subsidiaries is a party (collectively, the "Parent Real Property Leases") are
either filed as exhibits to the Parent SEC Reports or complete copies thereof
have been delivered to or made available to the Company. As of the date of this
Agreement, (i) all Parent Real Property Leases are in full force and effect
(except as such enforceability may be subject to laws of general application
relating to bankruptcy, insolvency and the relief of debtors and rules of law
governing specific performance, injunctive relief or other equitable remedies);
(ii) there is no existing material breach or violation of or default by Parent
under any of the Parent Real Property Leases; (iii) no event has occurred with
respect to Parent which, with notice or lapse of time or both, would constitute
a material breach, violation or default of any of the Parent Real Property
Leases; and (iv) to Parent's Knowledge, there are no material breaches, defaults
or violations of any obligations of the landlord under any Parent Real Property
Lease.

            Section 4.16 Taxes.

                  (a) Parent and each of its Subsidiaries have filed with the
appropriate taxing authorities all material Tax Returns required to be filed by
them and all such Tax Returns were true, complete and correct in all material
respects. All Taxes

                                       44


                                                                  EXECUTION COPY

required to be paid by Parent and each of its Subsidiaries have been timely
paid. There are no Tax Liens on any assets of Parent or any of its Subsidiaries
other than Liens relating to Taxes not yet due and payable. Neither Parent nor
any of its Subsidiaries has granted any outstanding waiver of any statute of
limitations with respect to, or any outstanding extension of a period for the
assessment of, any Tax. The accruals and reserves for Taxes (exclusive of any
accruals for "deferred taxes" or similar items that reflect timing differences
between tax and financial accounting principles) reflected in the Parent Balance
Sheet are adequate to cover all Taxes accruable through the date thereof
(including interest and penalties, if any, thereon and Taxes being contested) in
accordance with GAAP applied on a consistent basis with the Parent Balance
Sheet. All liabilities for Taxes attributable to the period commencing on the
date following the date of the Parent Balance Sheet were incurred in the
ordinary course of business and are consistent in type and amount with Taxes
attributable to similar prior periods.

                  (b) Parent and each of its Subsidiaries have timely withheld
with respect to its employees all federal and state Taxes required to be
withheld. Neither parent nor any of its Subsidiaries has received any notice of
any Tax deficiency outstanding, proposed or assessed against Parent or any of
its Subsidiaries. Neither Parent nor any of its Subsidiaries has received any
written notice of any audit examination, deficiency, refund litigation, proposed
adjustment or matter in controversy with respect to any Tax Return of Parent or
any of its Subsidiaries. Neither Parent nor any of its Subsidiaries is a party
to or bound by any tax indemnity, tax sharing or tax allocation agreements with
any entity other than Parent or any Parent Subsidiary. Except for the group of
which Parent and its Subsidiaries are now currently members, neither Parent nor
any of its Subsidiaries has ever been a member of an affiliated group of
corporations within the meaning of Section 1504 of the Code. Neither Parent nor
any of its Subsidiaries is liable for the Taxes of any person under Treasury
Regulation 1.1502-6 (or any similar provision of state, local or foreign Law) as
a transferee or successor, by contract or otherwise.

                  (c) To the extent requested by the Company, Parent made
available to the Company complete and correct copies of all income Tax Returns,
examination reports and statements of deficiencies assessed against or agreed to
by Parent or any of its Subsidiaries with respect to all taxable years for which
the statutes of limitation have not expired.

                  (d) Neither Parent nor any of its Subsidiaries has constituted
either a "distributing corporation" or a "controlled corporation" (within the
meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock
qualifying for tax-free treatment under Section 355 of the Code (A) in the two
years prior to the date of this Agreement or (B) in a distribution which could

            Section 4.18 Intellectual Property.

                  (a) All of the Parent Registered Intellectual Property is

                                                                  EXECUTION COPY

                  (d) There is no pending or, to Parent's Knowledge, threatened,
and at no time since June 29, 2002 through to the date of this Agreement has
there been pending any, material suit, arbitration or other adversarial
proceeding before any court, government agency or arbitral tribunal or in any
jurisdiction alleging that any activities or conduct of Parent's or any of its
Subsidiaries' business infringes or will infringe upon, violate or constitute
the unauthorized use of the Intellectual Property of any third party or
challenging the ownership, validity, enforceability or registerability of any
Intellectual Property owned by Parent or any of its Subsidiaries. Neither Parent

Parent and its Subsidiaries as currently conducted does not infringe upon,
violate or constitute the unauthorized use of any Intellectual Property rights
owned by any third party. Parent and its Subsidiaries have taken reasonable
measures to protect the proprietary nature of the Intellectual Property owned by
Parent and such Subsidiary that is material to the business of Parent and its
Subsidiaries as currently conducted. To Parent's Knowledge, no third party is
misappropriating, infringing, diluting or violating any Intellectual Property
owned by Parent or any of its Subsidiaries that is material to the business of
Parent and its Subsidiaries as currently conducted, and no material Intellectual
Property misappropriation, infringement dilution or violation suits,
arbitrations or other adversarial proceedings have been brought before any
court, government agency or arbitral tribunal against any third party by Parent
or any of its Subsidiaries which remain unresolved.

                  (f) Neither the Parent nor any of its Subsidiaries has
delivered (or granted a conditional release of) any of its source code contained
in any material proprietary product currently being marketed, sold, licensed or
developed by Parent or any of its Subsidiaries (each such product, a "Parent
Proprietary Product").

                  (g) Neither the Parent nor any of its Subsidiaries is in
violation of any material license, sublicense, agreement or instrument to which
the Parent or any of its Subsidiaries is party or otherwise bound under which
the Parent or its Subsidiaries derive rights to Intellectual Property that is
material to the Parent's or its Subsidiaries' business as currently conducted.

developed, processed, labeled, stored or distributed by or on behalf of Parent

are being manufactured, tested, developed, processed, labeled, stored,
distributed, and marketed in compliance with all applicable Laws, guidances or
orders administered or issued by the FDA or any other Governmental Entity,
including without limitation, the FDA's current Good Manufacturing Practice
regulations, except where any failure to so comply would not reasonably be
expected to have, individually or in the aggregate, a Parent Material Adverse
Effect. All applicable operations of Parent and each of its Subsidiaries have
achieved and maintained ISO 13485 Quality System certification, and there is no
pending or, to Parent's Knowledge threatened, audit, repeal, failure to renew or
challenge to any such certifications. All products being manufactured by Parent
or any of its Subsidiaries are in compliance with applicable registration,
licensing and notification requirements required by applicable Law for each site

individually or in the aggregate, a Parent Material Adverse Effect. All
pre-clinical and clinical trials being conducted by or on behalf of Parent or
any of its Subsidiaries are being conducted in compliance with all applicable
Laws and guidances of the FDA or any other Governmental Entity, including
without limitation, the FDA's current Good Clinical Practice regulations and
federal and state Laws, regulations and guidances restricting the use and
disclosure of individually identifiable health information except where any
failure to so comply would not reasonably be expected to have, individually or
in the aggregate, a Parent Material Adverse Effect. Neither Parent nor any of
its Subsidiaries is not the subject, officially or otherwise, of any pending or
threatened investigation by the FDA pursuant to its "Fraud, Untrue Statements of
Material Facts, Bribery, and Illegal Gratuities" Final Policy set forth in 56
Fed. Reg. 46191 (September 10, 1991) and any amendments thereto. Neither Parent
nor any of its Subsidiaries has committed any act, made any statement, or failed
to make any statement that would provide a basis for the FDA to invoke its
policy with respect to "Fraud, Untrue Statements of Material Facts, Bribery and
Illegal Gratuities" and any amendments thereto. To Parent's Knowledge, each
product distributed, sold or leased, or service rendered, by Parent or any of
its Subsidiaries complies in all material respects with all applicable product
safety standards of each applicable product safety agency, commission, board or
other Governmental Entity.

                  (b) The Parent and each of its Subsidiaries is in compliance
with all applicable FDA import and export requirements, including, but not
limited to, import-for-export requirements, export notifications or
authorizations and record keeping requirements except as would not reasonably be
expected to have, individually or in the aggregate, a Parent Material Adverse
Effect.

contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act,
or from making any other disclosure if the Company Board or the Parent Board, as
the case may be, determines in good faith (after consultation with its outside
legal counsel) that the failure to make such disclosure would be reasonably
likely to be a breach of its fiduciary duties under applicable law; provided,
however, that any action taken or disclosure made pursuant to such rules shall
not in any way limit or modify the effect that any action taken or disclosure
made pursuant to such rules has under any other provision of this Agreement.

                  (e) Nothing set forth in this Section 6.2 shall (i) permit

each of the Company Board and the Parent Board may effect a Change of
Recommendation or approve or recommend to its stockholders that they accept, or
propose publicly to adopt, approve or recommend, any Superior Proposal, provided
that (i) the Company or Parent, respectively, has received a Superior Proposal
and such Superior Proposal has not been withdrawn at the time such action is
taken, (ii) the Company Stockholders Meeting or the Parent Stockholders Meeting,
respectively, has not occurred, and (iii) the Board of Directors of the party

the party hereto that has received the foregoing notice shall make a
counterproposal to the party hereto that is proposing to effect a Change of

contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act,
or from making any other disclosure if the Company Board or the Parent Board, as
the case may be, determines in good faith (after consultation with its outside
legal counsel) that the failure to make such disclosure would be reasonably
likely to be a breach of its fiduciary duties under applicable Law; provided,
however, that any action taken or disclosure made pursuant to such rules shall

independent financial advisor of nationally recognized reputation and (ii)
taking into account all of the terms and conditions of such proposal and this
Agreement, including (A) any counterproposal by the other party to this
Agreement, (B) the likelihood that the transactions contemplated by such
Acquisition Proposal will close in a timely manner, and (C) the extent to which
the financing for the transactions contemplated by such Acquisition Proposal, to
the extent required, is committed or is capable of being obtained on the terms

the same time as the other Merger Stockholders Meeting.

                  (b) Subject to Section 6.3, to the fullest extent permitted by
applicable Law, (i) in the case of the Company, the Company Board shall

Company at the Company Stockholders Meeting and include such recommendation in

compliance with the DGCL, the NYSE, in the case of the Company, the Company
Charter and the Company Bylaws and, in the case of Parent, the Parent Charter
and the Parent Bylaws, and all other applicable legal requirements.
Notwithstanding anything to the contrary contained in this Agreement, each of
the Company or Parent, after consultation with the other, may adjourn or
postpone its respective Merger Stockholders Meeting to the extent necessary to
ensure that any required supplement or amendment to the Joint Proxy
Statement/Prospectus is provided to its respective stockholders or, if as of the
time for which the applicable Merger Stockholders Meeting is originally
scheduled (as set

or cause to be done, all things necessary, proper or advisable to consummate and
make effective, in the most expeditious manner possible, the Merger and the
other transactions contemplated hereby, including by (i) obtaining (and
cooperating with the other in obtaining) any clearance, consent, authorization,
order or approval of, or any exemption by, any Governmental Entity required to

affecting the ability of the parties to consummate the transactions contemplated
hereby, and (vi) executing any certificates, instruments or other documents that
are necessary to consummate and make effective the transactions contemplated
hereby and to fully carry out the purposes and intent of this Agreement.

                  (b) Each of the Company and Parent shall keep the other
reasonably informed of the status of their respective efforts to consummate the

supranational) with respect to the transactions contemplated hereby, (ii)
permitting 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)

                                       65


                                                                  EXECUTION COPY

advance and to the extent permitted by such Governmental Entity gives the other

such Governmental Entity with respect to this Agreement and the transactions
contemplated hereby, and (v) furnishing the other with such necessary

connection with its preparation of necessary filings or submissions of
information to any such Governmental Entity. 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 6.6 as "counsel
only" and, in such event, such material and the information contained therein
shall be given only to the legal counsel of the recipient and shall not be
disclosed by such counsel to non-legal directors, officers, employees or other
advisors or representatives of the recipient unless express permission is
obtained in advance from the source of the materials or its legal counsel.

                  (c) Notwithstanding anything to the contrary set forth in this
Section 6.6 or elsewhere in this Agreement, neither Parent nor any of its
affiliates shall be required to (i) sell or dispose of or hold separately
(through a trust or otherwise) any assets or businesses or interests in any
assets or businesses of Parent, the Company or their respective affiliates or
make any other change in any portion of the businesses of the Company or Parent
or incur any other limitation on the conduct of the businesses of the Company or
Parent to obtain such clearances, consents, authorizations, orders, approvals
and exemptions or agree to do, or submit to orders providing for, any of the
foregoing, in each case whether before or after the Effective Time, or (ii) if
any governmental body that has the authority to enforce any Antitrust Law seeks,
or authorizes its staff to seek, a preliminary injunction or restraining order
to enjoin consummation of the Merger, take or agree to take any action which
Parent reasonably believes would be prohibited or restricted under such
preliminary injunction or restraining order.

                  (d) In case at any time after the Effective Time any further
action is necessary to carry out the purposes of this Agreement or to vest the
Surviving Corporation with full title to all properties, assets, rights,
approvals, immunities and franchises of any of the parties to the Merger, the
proper officers and directors of each party hereto shall take all such necessary
action as may be reasonably requested by Parent to achieve such intent.

            Section 6.7 Rights Agreements.

                  (a) Prior to the Effective Time and for so long as this
Agreement shall not have been terminated pursuant to Article VIII, the Company
shall not, directly or indirectly, in connection with the execution, delivery or
performance of this Agreement and the transactions contemplated hereby (i) take
any action to deem Parent or Merger Sub to be an Acquiring Person, (ii) issue or
cause to be issued any Rights to stockholders of the Company as a result of any
actions taken by Parent, (iii) trigger any other provisions of the

                                       66


                                                                  EXECUTION COPY

Company Rights Agreement, including giving rise to a Distribution Date or a
Stock Acquisition Date, as a result of any actions taken by Parent, or (iv)
amend, modify (other than to delay any Distribution Date therein or to render
the Rights inapplicable to the Merger or any action permitted under this
Agreement) or terminate the Company Rights Agreement unless (A) required to do
so by order of a court of competent jurisdiction, or (B) the Company Board has
determined in good faith (after consultation with its outside legal counsel)
that the failure to take such action would be reasonably likely to be a breach
of its fiduciary duties under applicable Law.

                  (b) Prior to the Effective Time and for so long as this
Agreement shall not have been terminated pursuant to Article VIII, Parent shall
not, directly or indirectly, in connection with the execution, delivery or

Date, as a result of any actions taken by the Company or (iv) amend, modify
(other than to delay any Distribution Date therein or to render the Rights
inapplicable to the Merger or any action permitted under this Agreement) or
terminate the Company Rights Agreement unless (A) required to do so by order of
a court of competent jurisdiction, or (B) the Parent Board has determined in
good faith (after consultation with its outside legal counsel) that the failure
to take such action would be reasonably likely to be a breach of its fiduciary
duties under applicable Law.

            Section 6.8 Public Announcements.

            Parent and the Company shall consult with each other before issuing
any press release or making any public statement with respect to this Agreement
and the transactions contemplated hereby and shall not issue any such press
release or make any such public statement without the prior written consent of
the other party, which shall not be unreasonably withheld, delayed or
conditioned; provided, however, that a party may, without the prior consent of
the other party, issue such press release or make such public statement as may
upon consultation with outside counsel be required by applicable Law or the
rules and regulations of the NYSE if it has used all reasonable best efforts to
consult with the other party prior thereto regarding the timing, scope and
content of any such press release or public statement, and provided, further, no
such consultation shall be required to make any disclosure or otherwise take any
action expressly permitted by Section 6.3.

            Section 6.9 Employee Benefits; 401(k) Plan.

                  (a) From and after the Effective Time, Parent will, or will
cause the Surviving Corporation to, recognize the prior service with the Company
or its Subsidiaries of each employee of the Company or its Subsidiaries as of
the Effective Time (the "Company Employees") in connection with all employee

                                       67


                                                                  EXECUTION COPY

benefit plans, programs or policies (including vacation) of Parent or its
affiliates in which Company Employees are eligible to participate following the
Effective Time, for purposes of eligibility, vesting and levels of benefits (but
not for purposes of benefit accruals or benefit amounts under any defined
benefit pension plan or to the extent that such recognition would result in
duplication of benefits). From and after the Effective Time, Parent or the
Surviving Corporation shall provide Company Employees for so long as such
Company Employees remain so employed, health and welfare benefits pursuant to
employee benefit plans, programs, policies or arrangements maintained by Parent
or any Subsidiary of Parent providing coverage and benefits which are no less
favorable than those provided to employees of Parent in positions comparable to
positions held by Company Employees with Parent or its Subsidiaries from time to
time after the Effective Time. From and after the Effective Time, Parent will,
or will cause the Surviving Corporation to cause any pre-existing conditions or
limitations and eligibility waiting periods (to the extent that such waiting
periods would be inapplicable, taking into account service with the Company)
under any group health plans of Parent or its affiliates to be waived with
respect to Company Employees and their eligible dependents. Parent shall, or
shall cause the Surviving Corporation to, give each Company Employee credit for
any deductibles and annual out-of-pocket limits for medical expenses paid during
the applicable period under any welfare plans maintained or contributed to by
the Company prior to the Closing in satisfying any deductibles and annual
out-of-pocket limits for medical expenses for the corresponding period under any
welfare plans maintained or contributed to by Parent or its affiliates.

                  (b) Prior to the Effective Time, the Company shall take such
actions as Parent may reasonably request so as to enable the Surviving
Corporation to effect such actions relating to the Company 401(k) Plan (the
"401(k) Plan") as Parent may deem necessary or appropriate (after reasonable
consultation with the Company), including terminating the 401(k) Plan prior to
the Effective Time, subject to the terms of the 401(k) Plan and applicable Law
and provided that such action does not preclude the immediate participation of
the Company Employees in any successor plan.

            Section 6.10 Stock Plans.

                  (a) At the Effective Time, Parent shall assume the rights and
obligations of the Company with respect to the 2000 Plan as well as the duties
of the Company with respect to the administration of such plan.

                  (b) At the Effective Time, each Company Stock Option (other
than phantom units of Company Common Stock) that has an exercise price equal to
or less than $26.93 (the "Merger Consideration Value"), and is outstanding
immediately prior to the Effective Time, whether or not then vested or
exercisable (each, an "Assumed Option"), shall be fully vested and immediately
exercisable and assumed by Parent. In accordance with its terms, each Assumed
Option shall be converted into an option to acquire that number of shares of
Parent Common Stock equal to the sum of (x) the product of the number of shares
of Company

                                       68


                                                                  EXECUTION COPY

Common Stock subject to such Assumed Option immediately prior to the Effective
Time and the Exchange Ratio and (y) the quotient of the Cash Merger
Consideration divided by the Parent Closing Price (which sum shall be rounded
down to the nearest whole share), at a price per share equal to the aggregate
exercise price of Company Common Stock subject to such Assumed Option divided by
the number of shares determined under (x) and (y) above (which price per share
shall be rounded up to the nearest whole cent). The Assumed Option shall
otherwise be subject to the same terms and conditions as were applicable under
the respective Company Stock Option immediately prior to the Effective Time. It
is the intention of the parties that each Assumed Option that qualified as an
incentive stock option (as defined in Section 422 of the Code) shall continue to
so qualify, to the maximum extent permissible, following the Effective Time.

                  (c) Prior to the Closing Date, (i) each Company Stock Option
that has an exercise price in excess of the Merger Consideration Value and is
outstanding on the date hereof, whether or not then vested or exercisable (each,
a "Cancelled Option"), shall be fully vested and immediately exercisable; (ii)
the Company shall notify the holders of each such Cancelled Option that if such
options are not exercised within the period ending fifteen (15) days (thirty
(30) days in the case of Company Stock Options granted under the 1995 Director
Plan) from the date of such notice, such Cancelled Option shall expire as of the
last day of such period and be of no further force or effect.

                  (d) At the Effective Time, each Phantom Unit Account that
contains phantom units of Company Common Stock ("Phantom Units") immediately
prior to the Effective Time, whether or not then vested (each, an "Assumed
Phantom Unit Account"), shall be fully vested and assumed by Parent. Each
Assumed Phantom Unit Account shall be converted into a deferral account under
the 1995 Director Plan with respect to the phantom units of Parent Common Stock
equal to the sum of (i) the product of the number of Phantom Units in such
Assumed Phantom Unit Account immediately prior to the Effective Time and the
Exchange Ratio and (ii) the quotient of the Cash Merger Consideration divided by
the Parent Closing Price (which sum shall be rounded down to the nearest whole
share). The Assumed Phantom Unit Account and phantom units of Parent Common
Stock held therein shall otherwise be subject to the same terms and conditions
as were applicable to such Phantom Unit Account immediately prior to the
Effective Time.

                  (e) If and to the extent necessary or required by the terms of
any Company Stock Plan or any Company Stock Option, the Company shall, prior to
the Effective Time, amend the terms of its equity incentive plans or
arrangements, to give effect to the provisions of Sections 6.10(b) and 6.10(c).

                  (f) As soon as practicable following the Effective Time, but
in any event within five (5) business days thereafter (to the extent Parent has
received the most recent copies of the relevant Company Stock Plans), Parent
shall prepare and file with the SEC a registration statement on Form S-8
covering the shares of Parent Common Stock issuable pursuant to the outstanding
Assumed Options and Assumed Phantom Unit Accounts, Parent shall cause the same
to become effective, and Parent shall take such further

                                       69


                                                                  EXECUTION COPY

actions as may be reasonably necessary to cover under such registration
statement shares of Parent Common Stock held by those persons eligible
immediately prior to the Closing Date pursuant to the 1995 Director Plan.

            Section 6.11 Indemnification and Insurance.

                  (a) For six years after the Effective Time, Parent shall, and
shall cause the Surviving Corporation and its Subsidiaries to, honor and fulfill
in all respects the obligations of the Company and its Subsidiaries under any
and all indemnification agreements in effect immediately prior to the Effective
Time between the Company or any of its Subsidiaries and any of its current or
former directors and officers and any person who becomes a director or officer
of the Company or any of its Subsidiaries prior to the Effective Time (the
"Indemnified Parties"). In addition, for a period of six years following the
Effective Time, Parent shall (and shall cause the Surviving Corporation and its
Subsidiaries to) cause the certificate or articles of incorporation and bylaws
(and other similar organizational documents) of the Surviving Corporation and
its Subsidiaries to contain provisions with respect to indemnification and
exculpation that are at least as favorable as the indemnification and
exculpation provisions contained in the certificate or articles of incorporation
and bylaws (or other similar organizational documents) of the Company and its
Subsidiaries immediately prior to the Effective Time, and during such six year
period, such provisions shall not be amended, repealed or otherwise modified in
any respect, except as required by Law.

                  (b) For a period of six years after the Effective Time, Parent
and the Surviving Corporation shall cause to be maintained in effect the
existing policy of the Company's directors' and officers' and fiduciary
liability insurance (the "D&O Policy") covering claims arising from facts or
events that occurred at or prior to the Effective Time (including for acts or
omissions occurring in connection with this Agreement and the consummation of
the transactions contemplated hereby, to the extent that such acts or omissions
are covered by the D&O Policy) and covering each Indemnified Party who is
covered as of the Effective Time by the D&O Policy on terms with respect to
coverage and amounts that are no less favorable than those terms in effect on
the date hereof; provided, however, that in no event shall Parent or the
Surviving Corporation be required to expend in any one year an amount in excess
of 200% of the current annual premium paid by the Company (which annual premium
is set forth on Schedule 6.11(b) of the Company Disclosure Schedule) for such
insurance (such 200% amount, the "Maximum Annual Premium"); and provided,
further, that if the annual premiums of such insurance coverage exceed such
amount, Parent and the Surviving Corporation shall be obligated to obtain a
policy with the greatest coverage available for a cost not exceeding the Maximum
Annual Premium. Prior to the Effective Time, notwithstanding anything to the
contrary in this Agreement, the Company may purchase a six-year "tail" prepaid
policy on the D&O Policy on terms and conditions no less advantageous than the
D&O Policy, provided that the amount paid by the Company for such "tail" policy
shall not exceed six times the Maximum Annual Premium. In the event that the

                                       70


                                                                  EXECUTION COPY

Company purchases such a "tail" policy prior to the Effective Time, Parent and
the Surviving Corporation shall maintain such "tail" policy in full force and
effect and continue to honor their respective obligations thereunder, in lieu of
all other obligations of Parent and the Surviving Corporation under the first
sentence of this Section 6.11(b) for so long as such "tail" policy shall be
maintained in full force and effect.

                  (c) The obligations and liability of Parent, the Surviving
Corporation and its Subsidiaries under this Section 6.11 shall be joint and
several.

                  (d) The obligations under this Section 6.11 shall not be
terminated, amended or otherwise modified in such a manner as to adversely
affect any Indemnified Party (or any other person who is a beneficiary under the
D&O Policy or the "tail" policy referred to in paragraph (b) above (and their
heirs and representatives)) without the prior written consent of such affected
Indemnified Party or other person who is a beneficiary under the D&O Policy or
the "tail" policy referred to in paragraph (b) above (and their heirs and
representatives). Each of the Indemnified Parties or other persons who are
beneficiaries under the D&O Policy or the "tail" policy referred to in paragraph
(b) above (and their heirs and representatives) are intended to be third party
beneficiaries of this Section 6.11, with full rights of enforcement as if a
party thereto. The rights of the Indemnified Parties (and other persons who are
beneficiaries under the D&O Policy or the "tail" policy referred to in paragraph
(b) above (and their heirs and representatives)) under this Section 6.11 shall
be in addition to, and not in substitution for, any other rights that such
persons may have under the certificate or articles of incorporation, bylaws or
other equivalent organizational documents, any and all indemnification
agreements of or entered into by the Company or any of its Subsidiaries, or
applicable Law (whether at law or in equity).

                  (e) In the event that Parent, Surviving Corporation or any of
their Subsidiaries (or any of their respective successors or assigns) shall
consolidate or merge with any other person and shall not be the continuing or
surviving corporation or entity in such consolidation or merger, or transfers at
least 50% of its properties and assets to any other person, then in each case
proper provision shall be made so that the continuing or surviving corporation
or entity (or its successors or assigns, if applicable), or transferee of such
assets, as the case may be, shall assume the obligations set forth in this
Section 6.11.

            Section 6.12 Tax Matters.

            None of Parent, Merger Sub or the Company shall, and they shall not
permit any of their respective Subsidiaries to, take any action prior to or
following the Closing that would reasonably be expected to cause the Merger to

Board and the Parent Board;

                  (b) by either Parent or the Company, if the Merger shall not

that the right to terminate this Agreement under this Section 8.1(b) shall not
be available to any party that has breached its obligations under this
Agreement, provided such breach has been the principal cause of, or resulted in,
the failure of the Merger to be consummated on or before the Outside Date;

shall be effective unless concurrently therewith such party fulfills its
obligation under Section 8.3.

jurisdiction or governmental, regulatory or administrative agency or commission
shall have issued a nonappealable final order, decree or ruling or taken any

provisions of Sections 6.2 or 6.3, or (ii) the Company shall have breached or

if capable of being cured, shall not have been cured within 20 days following
receipt by the Company of written notice of such breach or failure from Parent

provisions of Sections 6.2 or 6.3, or (ii) Parent shall have breached or failed
to perform any of its representations, warranties, or other covenants or
agreements contained in this Agreement, which breach or failure to perform would

capable of being cured, shall not have been cured within 20 days following
receipt by Parent of written notice of such breach from the Company (it being

20 day period); or

aggregate Stock Merger Consideration pursuant to Section 2.4 would result in the
aggregate Stock Merger Consideration that would be issued to the holders of

            No failure or delay on the part of any party hereto in the exercise
of any right hereunder shall impair such right or be construed to be a waiver
of, or acquiescence in, any breach of any representation, warranty or agreement
herein, nor shall any single or partial exercise of any such right preclude any
