Compensatory Arrangements for Non-Employee Directors

Annual Retainer Fee:

     OSI Pharmaceuticals, Inc. (“OSI” or the “Company”) compensates its non-employee directors for
service on the Board of Directors. The annual cash retainer fee payable to the members of the
Board of Directors is set forth in the table below.

	 	 	 	 	 	 	 	 
	 
	 	Service	 	 	Annual Retainer Fee	 
	 	Chairman of the Board
	 	 	$	150,000	 	 
	 	Chairman of the Audit Committee
	 	 	$	90,000	 	 
	 	Member of Audit Committee
	 	 	$	75,000	 	 
	 	Member of Other Board Committee
	 	 	$	62,500	 	 
	 

Option Grants and Restricted Stock Awards:

     Each non-employee director receives an initial grant of options under the Plan upon his or her
initial election to the Board. Each individual who becomes a director receives an initial option
to purchase 25,000 shares of common stock and an award of 8,500 shares of restricted stock,
restricted stock units or deferred stock units upon his or her initial election to the Board.
Future appointees to the position of Chairman of the Board will receive an additional option to
purchase 25,000 shares of common stock and an additional award of 8,500 shares of restricted stock,
restricted stock units or deferred stock units upon his or her initial election as Chairman. The
restricted stock and restricted stock units represent the right of a director to receive one share
of OSI common stock upon vesting. Each deferred stock unit represent the right of a director to
receive one share of OSI common stock upon the earlier of the director’s termination from service
on the Board of Directors or on a date no earlier than two years from the date of grant, as
designated by the director.

     In addition to initial equity awards, non-employee directors receive annual equity grants
under the Plan. Non-employee directors with the exception of the Chairman of the Board receive an
option to purchase 3,000 shares of common stock and an award of 1,500 shares of restricted stock,
restricted stock units or deferred stock units upon each re-election for a one-year Board term.
The Chairman of the Board receives an option to purchase 6,000 shares of common stock and an award
of 3,000 shares of restricted stock restricted stock units or deferred stock units upon re-election
for a one-year Board term.

     The stock option awards and restricted stock awards, including restricted stock units and
deferred stock units, granted to the directors after June 14, 2006 vest annually over four years of
the date of grant. The option awards expire on the seventh anniversary of their respective grant
dates, subject to the earlier expiration upon the occurrence of certain events set forth under the
terms of the Plan. The exercise price of all option awards is equal to 100% of the fair market
value of the underlying common stock on the date of grant.

 

 

Post-Retirement Medical Benefits:

     Prior to April 2007, we provided post-retirement medical and life insurance benefits to
eligible employees and qualified dependents, and members of our Board of Directors. Eligibility was
based on age and service requirements. These benefits are subject to deductibles, co-payment
provisions and other limitations. In April 2007, we terminated this benefit and grandfathered the
directors who were eligible for participation in the plan at the time of termination (Mr. White and
Drs. Mehta and Granner).

AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER, dated as of August 6, 2007 (this “Agreement”), among
INTEGRA LIFESCIENCES HOLDINGS CORPORATION, a Delaware corporation (“Parent”), ICE
MERGERCORP, INC., a Delaware corporation and a direct wholly owned Subsidiary of Parent
(“Merger Sub”), and ISOTIS, INC., a Delaware corporation (the “Company”).

WITNESSETH:

     WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the Company have each
approved and declared advisable the merger of Merger Sub with and into the Company (the
“Merger”), upon the terms and subject to the conditions set forth in this Agreement,
pursuant to which each outstanding share of common stock, par value $0.0001 per share, of the
Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective
Time, other than shares owned or held directly or indirectly by Parent or the Company and Appraisal
Shares, will be converted into the right to receive $7.25 per share in cash;

     WHEREAS, Parent, Merger Sub and the Company desire to make certain representations,
warranties, covenants and agreements in connection with the transactions contemplated hereby and
also to prescribe various conditions to the transactions contemplated hereby; and

     NOW, THEREFORE, in consideration of the foregoing and the respective representations,
warranties, covenants and agreements set forth herein, and intending to be legally bound hereby,
the parties hereto agree as follows:

ARTICLE I.

THE MERGER

     Section 1.1. The Merger. Upon the terms and subject to the conditions hereof, at the
Effective Time, Merger Sub shall be merged with and into the Company and the separate existence of
Merger Sub shall thereupon cease, and the Company, as the surviving corporation in the Merger (the
“Surviving Corporation”), shall by virtue of the Merger continue its existence under the
laws of the State of Delaware.

     Section 1.2. Closing. Unless this Agreement shall have been terminated pursuant to
the provisions of Section 9.1, the closing of the Merger (the “Closing”) will take place on
the third Business Day after the satisfaction or waiver (subject to applicable law) of the
conditions (excluding conditions that, by their terms, cannot be satisfied until the Closing Date,
but subject to the satisfaction or, where permitted, waiver of those conditions as of the Closing)
set forth in Article VIII, unless another time or date is agreed to in writing by the parties
hereto (the date of the Closing, the “Closing Date”). The Closing shall be held at the
offices of Willkie Farr & Gallagher LLP, 787 Seventh Avenue, New York, New York 10019, unless
another place is agreed to in writing by the parties hereto.

 

 

     Section 1.3. Effective Time. Upon the Closing, the parties shall file with the
Secretary of State of the State of Delaware a certificate of merger (the “Certificate of
Merger”). The Merger shall become effective at such time as the Certificate of Merger is duly
filed with and accepted by the Secretary of State of the State of Delaware or at such subsequent
time as Parent and the Company shall agree and as shall be specified in the Certificate of Merger
(the date and time the Merger becomes effective being the “Effective Time”).

     Section 1.4. Effects of the Merger. The Merger shall have the effects set forth in
the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers, and franchises of the Company and Merger Sub
shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and
Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

     Section 1.5. Certificate of Incorporation. At the Effective Time, the certificate of
incorporation of the Company shall be amended to read in its entirety as the certificate of
incorporation of Merger Sub as in effect immediately prior to the Effective Time, except that the
name of the Company shall continue to be “IsoTis, Inc.” and the provisions of the certificate of
incorporation of the Company related to the incorporator of the Company shall not be amended, and
as so amended shall be the certificate of incorporation of the Surviving Corporation after the
Effective Time, and thereafter may be amended as provided therein or by law.

     Section 1.6. Bylaws. The bylaws of Merger Sub as in effect at the Effective Time
shall be the bylaws of the Surviving Corporation, and thereafter may be amended as provided therein
or by law.

     Section 1.7. Directors; Officers. The directors of Merger Sub immediately prior to
the Effective Time shall be the directors of the Surviving Corporation and the officers of the
Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation,
in each case until their respective successors are duly elected and qualified or until their death,
resignation or removal in accordance with the DGCL and the certificate of incorporation and bylaws
of the Surviving Corporation.

     Section 1.8. Effect on Capital Stock. At the Effective Time by virtue of the Merger
and without any action on the part of the holder thereof:

     (a) Each share of Company Common Stock issued and outstanding immediately prior to the
Effective Time (other than treasury shares and any shares held directly or indirectly by Parent
and, except as provided in Section 1.8(e), Appraisal Shares) shall be converted into the right to
receive $7.25 in cash, without interest (the “Merger Consideration”).

     (b) All shares of Company Common Stock shall cease to be outstanding and shall be canceled and
retired and shall cease to exist, and each holder of a certificate which immediately prior to the
Effective Time represented any such shares of Company Common

- 2 -

 

Stock (a “Certificate”) shall thereafter cease to have any rights with respect to such
shares of Company Common Stock, except the right to receive the Merger Consideration. Each
Treasury Share at the Effective Time shall, by virtue of the Merger, cease to be outstanding and
shall be canceled and no Merger Consideration or other consideration shall be delivered in exchange
therefor.

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

     (d) If prior to the Effective Time, the Company should split, combine or otherwise reclassify
the Company Common Stock, or pay a stock dividend or other stock distribution in Company Common
Stock, or otherwise change the Company Common Stock into any other securities, or make any other
such stock dividend or distribution in capital stock of the Company in respect of the Company
Common Stock, then the Merger Consideration will be appropriately adjusted to reflect such split,
combination, dividend or other distribution or change. For avoidance of doubt, the issuance of
shares of Company Common Stock pursuant to the Exchange Offer shall not give rise to any adjustment
contemplated by this Section 1.8(d).

     (e) Notwithstanding anything in this Agreement to the contrary, shares (the “Appraisal
Shares”) of Company Common Stock issued and outstanding immediately prior to the Effective Time
that are held by any holder who is entitled to demand and properly demands appraisal of such shares
pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL
(“Section 262”), shall not be converted into the right to receive the Merger Consideration
as provided in Section 1.8(a), but instead such holder shall be entitled to payment of the fair
value of such Appraisal Shares in accordance with the provisions of Section 262. At the Effective
Time, the Appraisal Shares shall no longer be outstanding and shall automatically be canceled and
shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time
represented Appraisal Shares shall cease to have any rights with respect thereto, except the right
to receive the fair value of such shares in accordance with the provisions of Section 262.
Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive,
withdraw or lose the right to appraisal under Section 262 or a court of competent jurisdiction
shall determine that such holder is not entitled to the relief provided by Section 262, then the
right of such holder to be paid the fair value of such holder’s Appraisal Shares under Section 262
shall cease and such Appraisal Shares shall be deemed to have been converted at the Effective Time
into, and shall have become, the right to receive the Merger Consideration as provided in Section
1.8(a). The Company shall serve prompt notice to Parent of any demands for appraisal of any shares
of Company Common Stock, withdrawals of any such demands and any other related instruments served
pursuant to the DGCL received by the Company, and Parent shall have the right to participate in and
direct all negotiations and proceedings with respect to such demands. The Company shall not,
without the prior written consent of Parent, make any payment with respect to, or settle or offer
to settle, any such demands, or agree to do or commit to do any of the foregoing.

- 3 -

 

     Section 1.9. Treatment of Options.

     (a) Each option to purchase shares of Company Common Stock (individually a “Company
Option” and collectively, the “Company Options”) outstanding immediately prior to the
Effective Time pursuant to any Company Stock Plan or otherwise will at the Effective Time be
cancelled and the holder of such Company Option will, in full settlement of such Company Option,
receive from the Company an amount (subject to any applicable withholding), if any, in cash equal
to the product of (x) the excess, if any, of the Merger Consideration over the exercise price per
share of Company Common Stock underlying such Company Option multiplied by (y) the number of shares
of Company Common Stock subject to such Company Option, whether or not vested or exercisable;
provided that the aggregate amount of such payment shall be rounded down to the nearest whole cent.
If the applicable exercise price of any Company Option equals or exceeds the Merger Consideration,
such Company Option shall be cancelled without payment of additional consideration, and all rights
with respect to such Company Option shall terminate as of the Effective Time. Parent shall pay, or
shall cause the Surviving Corporation to pay, the amount of cash payable in respect of each Company
Option as soon as practicable following the Effective Time, but in any event no later than ten (10)
Business Days following the Effective Time. The holders of Stock Options will have no further
rights in respect of any Company Options from and after the Effective Time.

     (b) Prior to the Effective Time, the Company will adopt such resolutions and take such other
actions as are necessary in order to (i) effectuate the actions contemplated by this Section 1.9 or
to otherwise cancel the Company Options prior to the Effective Time, and (ii) terminate each
Company Stock Plan, in each case without paying any consideration or incurring any debts or
obligations on behalf of the Company or the Surviving Corporation, provided that such resolutions
and actions shall expressly be conditioned upon the consummation of the Merger and the other
transactions contemplated hereby and shall be of no effect if this Agreement is terminated.

ARTICLE II.

EXCHANGE OF CERTIFICATES

     Section 2.1. Exchange Fund. At or prior to the Effective Time, Parent shall deposit
with American Stock Transfer and Trust Company or such other bank or trust company as Parent shall
determine and who shall be reasonably satisfactory to the Company (the “Exchange Agent”),
in trust for the benefit of holders of shares of Company Common Stock, for exchange in accordance
with Section 1.8, the cash to be paid pursuant to this Agreement in exchange for outstanding
Company Common Stock. Any cash deposited with the Exchange Agent shall hereinafter be referred to
as the “Exchange Fund.”

     Section 2.2. Exchange Procedures. As promptly as practicable after the Effective
Time, the Exchange Agent will send to each record holder of a Certificate, (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 delivery of the Certificates to the Exchange Agent and shall be
in a form and have such other provisions as Parent may reasonably specify) and (ii)

- 4 -

 

instructions for use in effecting the surrender of the Certificates in exchange for the Merger
Consideration. As soon as reasonably practicable after the Effective Time, each holder of a
Certificate, upon surrender of a Certificate to the Exchange Agent together with such letter of
transmittal, duly executed, and such other documents as may reasonably be required by the Exchange
Agent, shall be entitled to receive in exchange therefor a check in the amount equal to the per
share cash amount of the Merger Consideration (after giving effect to any required tax
withholdings), which such holder has the right to receive pursuant to Section 1.8. The Exchange
Agent shall accept such Certificates upon compliance with such reasonable terms and conditions as
the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal
exchange practices. No interest will be paid or will accrue on any cash payable upon due surrender
of the Certificates. In the event of a transfer of ownership of Company Common Stock which is not
registered in the transfer records of the Company, the Merger Consideration with respect to such
Company Common Stock shall be paid to such a transferee only if the Certificate representing such
shares of Company Common Stock is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and to evidence that any applicable stock transfer
taxes have been paid.

     Section 2.3. No Further Ownership Rights in Company Common Stock. The Merger
Consideration paid upon conversion of shares of Company Common Stock in accordance with the terms
of Article I and this Article II shall be deemed to have been paid in full satisfaction of all
rights pertaining to the shares of Company Common Stock.

     Section 2.4. Termination of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the holders of Certificates for twelve months after the Effective Time
shall be delivered to the Surviving Corporation or otherwise on the instruction of the Surviving
Corporation, and any holders of Certificates who have not theretofore complied with this Article II
shall thereafter look only to the Surviving Corporation and Parent (subject to abandoned property,
escheat or other similar laws) for the Merger Consideration with respect to the shares of Company
Common Stock formerly represented thereby to which such holders are entitled pursuant to Section
1.8.

     Section 2.5. No Liability. None of Parent, Merger Sub, the Company, the Surviving
Corporation or the Exchange Agent shall be liable to any Person in respect of any Merger
Consideration from the Exchange Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

     Section 2.6. Lost Certificates. If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to
be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such
Person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to such Certificate or other
documentation (including an indemnity in customary form) reasonably requested by Parent, the
Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the
applicable Merger Consideration with respect to the shares of Company Common Stock formerly
represented thereby.

- 5 -

 

     Section 2.7. Withholding Rights. Each of the Surviving Corporation and Parent shall
be entitled to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of shares of Company Common Stock and any holder of Company Options such
amounts as it is required to deduct and withhold with respect to the making of such payment under
the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations
promulgated thereunder (“Treasury Regulations”), or any provision of state, local or
foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or
Parent, as the case may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of Company Common Stock in respect of
which such deduction and withholding was made by the Surviving Corporation or Parent, as the case
may be.

     Section 2.8. Further Assurances. At and after the Effective Time, the officers and
directors of the Surviving Corporation will be authorized to execute and deliver, in the name and
on behalf of the Company or Merger Sub, any deeds, bills of sale, assignments or assurances and to
take and do, in the name and on behalf of the Company or Merger Sub, any other actions and things
to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right,
title and interest in, to and under any of the rights, properties or assets acquired or to be
acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

     Section 6.1. Employee Benefits.

     (a) Employees of Company and its Subsidiaries who continue their employment with the Surviving
Corporation or who become employees of Parent or any subsidiary of Parent (“Continuing
Employees”) shall be given credit for all service with the Company and its Subsidiaries (and
their respective predecessors) (or service credited by the Company and its Subsidiaries for similar
plans, programs or policies) under all employee benefit and fringe benefit plans, programs and
policies of the Parent or its affiliates in which they become participants for purposes of
eligibility, vesting and level of benefits (except to the extent such service credit will result in
benefit accrual under any defined benefit pension plans or otherwise result in a duplication of
benefits).

     (b) If a Continuing Employee becomes eligible to participate in any medical, dental or health
plan of the Parent or any of its affiliates, Parent shall cause such plan to (A) waive any
preexisting condition limitations for conditions covered under the applicable medical, health or
dental plans of the Company (the “Company Welfare Plans”) and (B) honor any deductible and
out-of-pocket expenses incurred by such employee and his or her beneficiaries under the Company
Welfare Plans during the portion of the applicable plan year preceding the Closing.

- 38 -

 

     (c) Except as provided in this Section 6.1, nothing in this Agreement shall limit or restrict
the right of Parent or any of its Subsidiaries to modify, amend, terminate or establish employee
benefit plans or arrangements, in whole or in part, at any time after the Effective Time.

     (d) No provision of this Section 6.1 shall create any third party beneficiary rights in any
Continuing Employee or any current or former director or consultant of the Company or its
Subsidiaries located in the United States in respect of continued employment (or resumed
employment) or any other matter.

     Section 6.2. Indemnification Continuation.

     (a) For purposes of this 6.2, (i) “Indemnified Person” shall mean any person who is
now, or has been at any time prior to the Effective Time, an officer or director of the Company or
who was serving at the request of the Company as an officer or director of another corporation,
joint venture or other enterprise, and can provide evidence thereof to Parent acceptable to Parent
in its sole discretion and (ii) “Proceeding” shall mean any claim, action, suit, proceeding
or investigation.

     (b) From and after the Effective Time, Parent shall, or Parent shall cause the Surviving
Corporation, to provide indemnification to each Indemnified Person to the same extent and under
similar conditions and procedures as such Indemnified Person is entitled on the date hereof in
connection with any Proceeding based directly or indirectly (in whole or in part) on, or arising
directly or indirectly (in whole or in part) out of, the fact that such Indemnified Person is or
was an officer or director of the Company, or is or was serving at the request of the Company as an
officer or director of another corporation, joint venture or other enterprise or general partner of
any partnership or a trustee of any trust, whether pertaining to any matter arising before or after
the Effective Time. An Indemnified Person shall repay the Surviving Corporation for any expenses
incurred by Surviving Corporation in connection with the indemnification of such Indemnified Person
pursuant to this Section 6.2 if it is ultimately determined that such Indemnified Person did not
meet the standard of conduct necessary for indemnification by the Surviving Corporation.

     (c) Parent shall, or shall cause the Surviving Corporation to, provide or maintain in effect
for six years from the Effective Time (the “Tail Period”), through the purchase of run-off
coverage or otherwise, directors’ and officers’ liability insurance covering the Indemnified
Persons who are covered by the directors’ and officers’ liability insurance policy provided for
directors and officers of the Company and its Subsidiaries as of the date hereof (the “Existing
Policy”) on terms substantially comparable in the aggregate to the Existing Policy; provided,
however, that in no event shall the Surviving Corporation be required to expend in the aggregate in
excess of 200% of the current annual premium paid by the Company for such insurance with respect to
the Tail Period, and if the premiums of such insurance coverage exceed such amount, the Surviving
Corporation shall be obligated to maintain or obtain a policy with the greatest coverage available
for a cost not exceeding such amount. In lieu of the foregoing, the Company or the Surviving
Corporation may purchase, a six-year “tail” prepaid officers’ and directors’ liability insurance
policy in respect of acts or omissions occurring at or prior to the Effective Time covering each
such Indemnified Person.

- 39 -

 

     (d) The provisions of this Section 6.2 shall survive the consummation of the Merger for a
period of six years and are expressly intended to benefit each of the Indemnified Persons;
provided, however, that in the event that any claim or claims for indemnification are asserted or
made within such six-year period, all rights to indemnification in respect of any such claim or
claims shall continue until disposition of any and all such claims.

     (e) In the event that Parent or the Surviving Entity or any of their respective successors or
assigns (i) consolidates with or merges into any other Person and is not the continuing or
surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or
substantially all its properties and assets to any Person, then, and in each such case, Parent
shall cause proper provisions to be made so that the successors and assigns of Parent or the
Surviving Entity, as the case may be, assume the obligations set forth in this Section 6.2.

ARTICLE VII.

ADDITIONAL COVENANTS OF THE PARTIES.

     Section 7.1. Preparation of Proxy Statement, Company Stockholders Meeting.

     (a) As promptly as practicable, the Company shall prepare and file the Proxy Statement with
the SEC provided, that the Company shall consult with Parent and provide Parent a reasonable
opportunity to review and comment on such preliminary Proxy Statement prior to filing. The parties
shall reasonably cooperate with each other in the preparation of the Proxy Statement and to have
such document cleared by the SEC as promptly as practicable after such filing. The Proxy Statement
shall include the recommendation of the Board of Directors of the Company in favor of approval and
adoption of this Agreement and the Merger, except to the extent the Board of Directors of the
Company shall have withdrawn or modified its approval or recommendation of this Agreement to the
extent such action is permitted by Section 7.4. The Company shall use its reasonable best efforts
to cause the Proxy Statement to be mailed to its stockholders as promptly as practicable upon the
earlier of (x) receiving notification that the SEC is not reviewing the Proxy Statement and (y) the
conclusion of any SEC review of the Proxy Statement. The Company shall promptly provide copies,
consult with Parent and prepare written responses with respect to any written comments received
from the SEC with respect to the Proxy Statement and advise Parent of any oral comments received
from the SEC. The Proxy Statement shall comply as to form in all material respects with the rules
and regulations promulgated by the SEC under the Exchange Act.

     (b) The Company shall make all necessary filings with respect to the Merger and the
transactions contemplated thereby under the Exchange Act and the rules and regulations thereunder.
The Company will advise Parent, promptly after it receives notice thereof, of any request by the
SEC for amendment of the Proxy Statement or comments thereon and responses thereto or requests by
the SEC for additional information. No amendment or supplement to the Proxy Statement shall be
filed without the prior approval of Parent, which approval shall not be unreasonably withheld or
delayed. If at any time prior to

- 40 -

 

the Effective Time, any information relating to Parent or the Company, or any of their
respective Affiliates, officers or directors, should be discovered by Parent or the Company that
should be set forth in an amendment or supplement to the Proxy Statement, so that such documents
would not include any misstatement of a material fact or omit to state any material fact necessary
to make the statements therein, in light of the circumstances under which they were made, not
misleading, the party which discovers such information shall promptly notify the other parties
hereto and an appropriate amendment or supplement describing such information shall be promptly
filed with the SEC and, to the extent required by law, disseminated to the stockholders of the
Company.

     (c) The Company shall cause the Company Stockholders Meeting to be duly called and held as
soon as reasonably practicable for the purpose of obtaining the Required Company Vote. In

requirements applicable to such meeting.

     Section 7.2. Access to Information. Upon reasonable notice, the Company shall (and
shall cause its Subsidiaries to) afford to Parent and its representatives reasonable access during
normal business hours, during the period prior to the Effective Time, to all its officers,
employees, properties, offices, plants and other facilities and to all books and records and,
during such period, the Company shall (and shall cause its Subsidiaries to) furnish promptly to
Parent and its representatives, consistent with its legal obligations, all other information
concerning its business, properties and personnel as Parent may reasonably request; provided,
however, that the Company may restrict the foregoing access to the extent that, in the Company’s
reasonable judgment, (i) providing such access would result in the disclosure of any trade secrets
of third parties or violate any of its obligations with respect to confidentiality if the Company
shall have used all reasonable efforts to obtain the consent of such third party to such access, or
(ii) any law, treaty, rule or regulation of any Governmental Entity applicable to the Company
requires the Company or its Subsidiaries to preclude Parent and its representatives from gaining
access to any properties or information. Parent will hold any such information that is non-public
in confidence to the extent required by, and in accordance with, the provisions of that certain
Confidentiality Agreement, dated May 14, 2007 (the “Confidentiality Agreement”), between
the Company and Parent.

     Section 7.3. Efforts.

     (a) Subject to the terms and conditions of this Agreement, each party will use its
commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to
be done, all things necessary, proper or advisable under applicable laws and regulations to
consummate the Merger and the other transactions contemplated by this Agreement as soon as
practicable after the date hereof. In furtherance and not in limitation of the foregoing, if
applicable, each party hereto agrees to make any filing required by any applicable Regulatory Law
(as defined below) with respect to the transactions contemplated hereby as promptly as practicable,
and to supply as promptly as practicable any additional information and documentary material that
may be requested pursuant to such applicable Regulatory Law and to take all other actions
necessary to cause the expiration or termination of the applicable waiting periods under such
applicable Regulatory Law as soon as practicable.

- 41 -

 

     (b) Each of Parent and the Company shall, in connection with the efforts referenced in Section
7.3 to obtain all requisite approvals and authorizations for the transactions contemplated by this
Agreement under any Regulatory Law (as defined below), use its commercially reasonable best efforts
to (i) cooperate in all respects with each other in connection with any filing or submission and in
connection with any investigation or other inquiry, including any proceeding initiated by a private
party; (ii) promptly inform the other party of any communication received by such party from, or
given by such party to any governmental authority and of any material communication received or
given in connection with any proceeding by a private party, in each case regarding any of the
transactions contemplated hereby, and (iii) permit the other party to review any communication
given by it to, and consult with each other in advance of any meeting or conference with any
governmental authority or, in connection with any proceeding by a private party, with any other
Person, and to the extent permitted by the applicable governmental authority or other Person, give
the other party the opportunity to attend and participate in such meetings and conferences. For
purposes of this Agreement, “Regulatory Law” means the Sherman Act, as amended, the Clayton
Act, as amended, the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, the Federal
Trade Commission Act, as amended, and all other federal, state and foreign, if any, statutes,
rules, regulations, orders, decrees, administrative and judicial doctrines and other laws that are
designed or intended to prohibit, restrict or regulate actions having the purpose or effect of
monopolization or restraint of trade or lessening of competition through merger or acquisition. In
furtherance and not in limitation of the covenants of the parties contained in Section 7.3 and this
Section 7.4(b), each party hereto shall use its reasonable best efforts to resolve objections, if
any, as may be asserted with respect to the transactions contemplated by this Agreement under any
Regulatory Law. Notwithstanding anything to the contrary contained in this Agreement, in connection
with any filing or submission required or action to be taken by either Parent or the Company to
consummate the Merger, in no event shall Parent or any of its Subsidiaries or Affiliates be
obligated to propose or agree to accept any undertaking or condition, to enter into any consent
decree, to make any divestiture, or accept any operational restriction, or take or commit to take
any action that could reasonably be expected to limit (A) the freedom of action of Parent or its
Subsidiaries or Affiliates with respect to the operation of, or Parent’s or its Subsidiaries’ or
Affiliates’ ability to retain, the Company or any businesses, product lines or assets of the
Company, or (B) the ability to retain, own or operate any portion of the businesses, product lines,
or assets, of Parent or any of its Subsidiaries or Affiliates, or alter or restrict in any way the
business or commercial practices of the Company, Parent or its Subsidiaries or Affiliates.

     (c) The parties shall use their commercially reasonable efforts to obtain all consents,
waivers, authorizations and approvals of all third parties, including Governmental Entities,
necessary, proper or advisable for the consummation of the transactions contemplated by this
Agreement; provided that, without the prior written consent of Parent, the Company shall not incur
any significant expense or liability or agree to any significant modification to any contractual
arrangement to obtain such consents or certificates, and to provide any notices to third parties
required to be provided prior to the Effective Time.

     Section 7.4. Acquisition Proposals.

     (a) None of the Company or any of its Subsidiaries shall (whether directly or indirectly
through Affiliates, directors, officers, employees, representatives or other intermediaries), nor
shall (directly or indirectly) the Company authorize or permit any of its or their officers,
directors, representatives or other intermediaries or Subsidiaries to, (i) solicit, initiate or
take any action to knowingly facilitate or encourage the submission of inquiries, proposals or
offers from any Person (other than Parent and Merger Sub) relating to any Acquisition Proposal, or

any information with respect to its business, properties or assets in connection with any
Acquisition Proposal or inquiry with respect to any Acquisition Proposal; or (iv) agree to resolve
or take any of the actions prohibited by clause (i), (ii) or (iii) of this sentence. The Company

cease, any and all existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any of the foregoing and shall demand the return or destruction of any
information previously provided with respect to such activities, discussion, or negotiations. For
purposes of this Section 7.4, the term “Person” means any person, corporation, entity or
“group,” as defined in Section 13(d) of the Exchange Act, other than Parent or any Subsidiaries of
Parent.

     “Acquisition Proposal” means any offer or proposal for a merger, reorganization,
recapitalization, consolidation, share exchange, business combination or other similar transaction
involving the Company or any of the Subsidiaries (excluding the transactions contemplated by the
Exchange Offer) or any proposal or offer to acquire, directly or indirectly, securities
representing more than 20% of the voting power of the Company or more than 20% of the assets of the
Company and the Subsidiaries taken as a whole, other than the Merger contemplated by this
Agreement.

     (b) Notwithstanding the foregoing, the Board of Directors of the Company, directly or
indirectly through representatives or other intermediaries, may, in the event of an Acquisition
Proposal, (i) comply with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act with regard

modify or amend its recommendation of the Merger except to the extent such action is permitted by
clause (iv) of this Section 7.4(b), (ii) engage in negotiations or discussions with any Person that

nonpublic information relating to the Company or any of the Subsidiaries pursuant to a
confidentiality and standstill agreement (the “Competing Confidentiality Agreement”) with
terms that are no less favorable to the Company than those contained in the Confidentiality
Agreement (it being understood that the standstill provision contained in such Competing
Confidentiality Agreement may permit such Person to convey confidentially an Acquisition Proposal
to the Board of Directors of the Company under circumstances in which the Company is permitted
under this Section 7.4 to

- 43 -

 

participate in discussions regarding an Acquisition Proposal), and/or (iv) if prior to the
Company Stockholders Meeting, withdraw or modify or change in a manner adverse to Parent its
approval or recommendation of this Agreement or the Merger; provided that, the Board of Directors
of the Company shall be permitted to take an action described in the foregoing clauses (i), (ii),
(iii) or (iv) if, and only if, prior to taking such particular action, the Board of Directors of
the Company has determined in good faith by a majority vote that (x) such Acquisition Proposal
would result in, or would reasonably be expected to result in, a Superior Proposal, in the case of
any of the foregoing clauses (i), (ii) or (iii), or constitutes a Superior Proposal, in the case of
the foregoing clause (iv), and (y) (after considering the advice of outside legal counsel) failing
to take such action in the case of any of the foregoing clauses (i), (ii) or (iii) would reasonably
be expected to result in a breach of its fiduciary duties under the DGCL or in the case of the
foregoing clause (iv) would result in a breach of its fiduciary duties under the DGCL.
Notwithstanding the foregoing, in response to an Intervening Event, the Board of Directors of the
Company may withdraw or modify or change in a manner adverse to Parent its approval or
recommendation of this Agreement or the Merger, if and only if, the Board of Directors of the
Company, after considering the advice of outside legal counsel, has determined that failing to take
such action would result in a breach of its fiduciary duties under the DGCL.

	 	i)	 	“Superior Proposal” means any proposal (on its most
recently amended or modified terms, if amended or modified) made by a third
party to enter into any transaction involving an Acquisition Proposal that the
Board of Directors of the Company determines in its good faith judgment
(following consultation with an independent financial advisor) to be more
favorable to the Company’s stockholders than this Agreement and the Merger,
taking into account all terms and conditions of such transaction (including any
break-up fees, expense reimbursement provision and financial terms, the
anticipated timing, conditions and prospects for completion of such
transaction, including the prospects for obtaining regulatory approvals and
financing, and any third party approvals) and that is reasonably likely to be
consummated, except that the reference to “more than 20%” in the definition of
“Acquisition Proposal” shall be deemed to be a reference to “more than 50%”.
Reference to “this Agreement” and “the Merger” in this paragraph shall be
deemed to include any proposed alteration of the terms of this Agreement or the
Merger that are agreed to by Parent after it receives written notice from the
Company pursuant to Section 7.4(d) of the existence of, the identity of the
Person making, and the terms and conditions of, any Acquisition Proposal.

     (c) Notwithstanding anything in this Section 7.4 to the contrary, if, at any time prior to the
Company Stockholders Meeting, the Company’s Board of Directors determines in good faith, after
consultation with its financial advisors and outside legal counsel, in response to an Acquisition
Proposal that was unsolicited and that did not otherwise result from a breach of Section 7.4(a),
that such proposal is a Superior Proposal, the Company or its Board of Directors may, pursuant to
and subject to complying with Section 9.1(f), accept such Superior Proposal; provided, however,
that prior to any such acceptance of such Superior

- 44 -

 

Proposal, the Company shall have given Parent five (5) Business Days’ written notice (it being
understood and agreed that any amendment to the amount or form of consideration of the Superior
Proposal shall require a new notice pursuant to this Section 7.4(c) except that all references in
this Section 7.4(c) to five (5) Business Days shall be deemed to be references to three (3)
Business Days in such event) advising Parent that the Company’s Board of Directors intends to cause
the Company to accept such Superior Proposal, specifying the material terms and conditions of the
Superior Proposal and that the Company shall, during such five (5) Business Day period, negotiate
in good faith with Parent to make such adjustments to the terms and conditions of this Agreement
such that such Acquisition Proposal would no longer constitute a Superior Proposal and provided
further, however, that after the expiration of such five (5) Business Day period and prior to the
termination of this Agreement pursuant to Section 9.1(f), the Company’s Board of Directors shall
have confirmed (after taking into account any such adjustments to the terms and conditions of this
Agreement) that the Acquisition Proposal continues to be a Superior Proposal.

     (d) The Company shall notify Parent promptly (but in any event within one Business Day) after
receipt or occurrence of (i) any Acquisition Proposal, (ii) any request for information with
respect to any Acquisition Proposal, (iii) any inquiry, proposal, discussions or negotiation with
respect to any Acquisition Proposal, and (iv) the material terms and conditions of any such
Acquisition Proposal, request for information, inquiry, proposal, discussion or negotiation and the
identity of the Person making any such Acquisition Proposal, request for information, inquiry or
proposal or with whom discussions or negotiations are taking place. In addition, the Company shall
promptly (but in any event within one Business Day) after the receipt thereof, provide to Parent
copies of any written documentation material to understanding such Acquisition Proposal, request
for information, inquiry, proposal, discussion or negotiation (“Other Acquisition
Documentation”) which is received by the Company from the Person (or from any representatives
or agents of such Person) making such Acquisition Proposal, request for information, inquiry or
proposal or with whom such discussions or negotiations are taking place. The Company shall not,
and shall cause each of its Subsidiaries not to, terminate, waive, amend or modify any provision of
any existing standstill or confidentiality agreement to which it or any of its Subsidiaries is a
party, and the Company shall, and shall cause its Subsidiaries to, enforce the provisions of any
such agreement (it being understood that the Company may waive any standstill provision to the
extent necessary to permit any Person subject to such standstill provision to convey confidentially
an Acquisition Proposal to the Board of Directors of the Company under circumstances in which the
Company is permitted under this Section 7.4 to participate in discussions regarding an Acquisition
Proposal). The Company shall keep Parent reasonably informed of the status and details (including
any material amendments or proposed material amendments) of any such Acquisition Proposal or
request for information and keep Parent reasonably informed as to the material details of any
information requested of or provided by the Company and as to the material details of all
substantive discussions or negotiations with respect to any such Acquisition Proposal, request for
information, inquiry or proposal and shall provide to Parent within one Business Day after receipt
thereof all copies of any additional Other Acquisition Documentation received by the Company from
the Person (or from any representatives or agents of such Person) making such Acquisition Proposal,
request for information, inquiry or proposal or with whom such discussions or negotiations are
taking place. The Company shall promptly provide to Parent any non-public information concerning

- 45 -

 

the Company provided to any other Person in connection with any Acquisition Proposal that was
not previously provided to Parent. The Board of Directors of the Company shall promptly consider
in good faith (in consultation with its outside legal counsel and financial advisors) any proposed
alteration of the terms of this Agreement or the Merger proposed by Parent in response to any
Acquisition Proposal.

     Section 7.5. Stockholder Litigation. The Company shall keep Parent informed of, and
cooperate with Parent in connection with, any stockholder litigation or claim against the Company
and/or its directors or officers relating to the Merger or the other transactions contemplated by
this Agreement; provided, however, that no settlement in connection with such stockholder
litigation shall be agreed to without Parent’s prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed.

     Section 7.6. Maintenance of Insurance. The Company will use reasonable best efforts
to maintain in full force and effect through the Closing Date all material insurance policies
applicable to the Company and its Subsidiaries and their respective properties and assets in effect
on the date hereof. If and as requested by Parent, the Company will use reasonable best efforts to
cause the Company’s insurers to waive any provisions in such insurance policies that would allow
the insurer to terminate or adversely modify coverage upon consummation of the Merger.

     Section 7.7. Public Announcements. Each of the Company, Parent and Merger Sub agrees
that no public release or announcement concerning the transactions contemplated hereby shall be
issued by any party without the prior written consent of the Company and Parent (which consent
shall not be unreasonably withheld or delayed), except as such release or announcement may be
required by law or the rules or regulations of any applicable United States securities exchange, in
which case the party required to make the release or announcement shall use its reasonable best
efforts to allow each other party reasonable time to comment on such release or announcement in
advance of such issuance, it being understood that the final form and content of any such release
or announcement, to the extent so required, shall be at the final discretion of the disclosing
party; provided, however, that upon prior consultation with the other party, each of the parties
may make statements that are not inconsistent with previous press releases, public disclosures or
public statements made by any of the parties in compliance with this Section 7.7.

     Section 7.8. No Shareholder Rights Plan. From the date hereof through the earlier of
termination of this Agreement and the Effective Time, the Company will not adopt, approve, or agree
to adopt, a shareholder rights plan.

     Section 7.9. European Restructuring. The Company shall use commercially reasonable
efforts to complete the restructuring of its European operations, including using commercially
reasonable efforts to accomplish the each of the actions set forth on Section 7.9 of the Company
Disclosure Letter.

of Directors;

     (b) By either the Company or Parent if the Effective Time shall not have occurred on or before
February 6, 2008 (the “Termination Date”); provided, however, that the right to terminate

Directors’ approval or recommendation of this Agreement or the Merger or approval or
recommendation of a Superior Proposal;

     (f) By the Company, prior to the Company Stockholders Meeting, to accept a Superior Proposal

of being cured or (B) in the case of a breach of a covenant or agreement, if such breach is
reasonably capable of being cured, such breach shall not have been cured prior to the earlier of

this Agreement or otherwise shall not constitute a waiver of those rights.
