The principal executive offices of the Company are located at 77 Great Valley Parkway, Malvern, Pennsylvania 19355.

Item 2.

Identity and Background.

This Statement is being filed jointly Stryker Corporation, a Michigan corporation, (“Stryker”), and Owl Acquisition Corporation, a Delaware corporation (“Purchaser”). The agreement by and among Stryker and Purchaser relating to the joint filing of this Statement is attached as Exhibit 5 hereto.

Stryker’s principal business and principal office address is 2825 Airview Boulevard, Kalamazoo, Michigan 49002. Purchaser’s principal business and principal office address is 2825 Airview Boulevard, Kalamazoo, Michigan 49002.

Stryker is one of the world’s leading medical technology companies. It provides innovative orthopaedic implants as well as state-of-the-art medical and surgical equipment to help people lead more active and more satisfying lives. Stryker’s products include implants used in joint replacement, trauma and spinal surgeries; surgical equipment and surgical navigation systems; endoscopic and communications systems; patient handling and emergency medical equipment as well as other medical device products used in a variety of medical specialties. Purchaser is an indirect wholly owned subsidiary of Stryker. Purchaser is a Delaware corporation formed on May 13, 2011 solely for the purpose of completing the Offer (as defined below) and the Merger (as defined below) and has conducted no business activities other than those related to the structuring and negotiation of the Offer and the Merger.

The name, business address, present principal occupation or employment and citizenship of each director and executive officer of Stryker and Purchaser are set forth on Schedule I hereto.

Neither Stryker nor Purchaser, nor, to the best of Stryker’s or Purchaser’s knowledge, has any of the individuals referred to in Schedule I, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws, or finding violations with respect to such laws during the last five years.

The Offer is not conditioned upon any financing arrangements. Stryker and Purchaser estimate that the total amount of funds required to purchase all of the outstanding Shares pursuant to the Offer and the Merger will be approximately $316 million plus related transaction fees and expenses. Stryker intends to provide Purchaser with the funds necessary to fund these payments with cash on hand.


		Page 6 of 17

Item 4.

Purpose of Transaction.

On May 16, 2011, Stryker, Purchaser and the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”). The Merger Agreement provides for the commencement of a tender offer by Purchaser to purchase all Shares of the Company, at a price of $3.85 per Share, net to the seller in cash (the “Offer”), without interest and subject to any withholding taxes.

The Merger Agreement provides, among other things, that after the consummation of the Offer and subject to certain conditions, Purchaser will be merged with and into the Company (the “Merger”) with the Company continuing as the surviving corporation (the “Surviving Corporation”), wholly owned by Stryker. Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each Share issued and outstanding immediately prior to the Effective Time (other than Shares held (i) by the Company or any wholly-owned subsidiary of the Company or by Stryker or Purchaser, which Shares will be canceled and cease to exist or (ii) by shareholders who validly exercise dissenters rights under Pennsylvania law, if applicable, with respect to such Shares) will be cancelled and converted into the right to receive the $3.85, without interest, payable net to the holder in cash, without interest and subject to any withholding of taxes.

The consummation of the Offer is subject to several closing conditions, including (i) that a majority of the outstanding Shares (determined on a fully diluted basis) be validly tendered and not withdrawn prior to the expiration of the Offer, (ii) the expiration or termination of any waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (iii) the absence of a material adverse effect on the Company and (iv) certain other customary conditions.

In connection with the execution of the Merger Agreement, Stryker and Purchaser entered into the Tender and Voting Agreements with Essex Woodlands Health Ventures Fund VII, L.P., and the following directors and officers of the Company (collectively, the “Tendering Shareholders”), Christine J. Arasin, Scott Barry, Nancy C. Broadbent, Morris Cheston, Jr., Theodore D. Clineff, Kevin B. Connolly, Antony Koblish, Michael J. Leonard, Jeffrey G. Marx, Mary Paetzold, Maarten Persenaire, Christopher H. Smith, Paul Thomas, William E. Tidmore, Jr. and Paul T. Touhey, Jr. The Tendering Shareholders own an aggregate of 10,231,348 Shares representing approximately 13.28% of the 77,028,457 Shares outstanding as of May 13, 2011. The Tendering Shareholders also hold options to acquire 6,279,248 Shares. Under the terms of the Tender and Voting Agreements, any Shares received by the Tendering Shareholders upon the exercise of stock options are subject to the provisions of the Tender and Voting Agreements.

Pursuant to the Tender and Voting Agreements, each Tendering Shareholder agreed to tender all of such holder’s outstanding shares into the Offer. Each Tendering Shareholder also


		Page 7 of 17

irrevocably appointed Stryker such holder’s proxy to vote such holder’s Shares (i) in favor of the Merger or any other transaction pursuant to which Stryker or Purchaser proposes to acquire the Company in which shareholders of the Company would receive consideration for their Shares equal to or greater than the consideration to be received by such shareholders in the Offer and the Merger, and/or (ii) against any action or agreement which would impede, interfere with or prevent the Merger, including, but not limited to, any other extraordinary corporate transaction, including a merger, acquisition, sale, consolidation, reorganization or liquidation involving the Company and a third party, or any other proposal of a third party to acquire the Company.

The Tender and Voting Agreements terminate upon the earlier to occur of (i) the Effective Time and (ii) the date of termination of the Merger Agreement in accordance with its terms.

The purpose of the Offer is to acquire control of, and the entire equity interest in, the Company. The purpose of the Merger is to acquire all outstanding Shares not tendered and purchased pursuant to the Offer. If the Offer is successful, Purchaser intends to consummate the Merger as promptly as practicable.

Pursuant to the terms of the Merger Agreement, promptly upon the acceptance for payment of any Shares pursuant to the Offer, Stryker currently intends to seek maximum representation on the Board of Directors of the Company (the “Company Board”), subject to the requirement in the Merger Agreement that at least three directors that were members of the Company Board as of the date of the Merger Agreement remain directors of the Company Board from the election or appointment of Stryker’s designees to the Company Board until the Effective Time.

As of the date of this Statement, no determination has been made as to which directors of the Company as of the date of the Merger Agreement will continue to serve as directors of the Company following the election or appointment of Stryker’s designees to the Company Board. Stryker intends to select its designees for directors of the Company from the persons listed in Schedule I hereto. It is expected that the first of the Stryker designees to assume office would assume office promptly following the purchase by Purchaser of Shares pursuant to the Offer, which purchase cannot be earlier than the expiration of the Offer, and that, upon assuming office, the Stryker designees will thereafter constitute at least a majority of the entire Company Board.

The Merger Agreement provides that at the Effective Time, the articles of incorporation of the Company will be amended and restated in its entirety to read as set forth in the Merger Agreement and the bylaws of Purchaser will be the bylaws of the Surviving Corporation, except that the name of the Surviving Corporation will continue to be Orthovita, Inc. The Merger Agreement also provides that, at the Effective Time, the directors and officers of Purchaser will be the directors of the Surviving Corporation.

The Shares are currently registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Such registration may be terminated upon application of the Company to the SEC if the Shares are neither listed on a national securities exchange nor held by


		Page 8 of 17

300 or more holders of record. Stryker intends and will cause the Company to terminate the registration of the Shares under the Exchange Act as soon after consummation of the Offer as the requirements for termination of registration are met. If registration of the Shares is not terminated prior to the Merger, the registration of the Shares under the Exchange Act will be terminated following the consummation of the Merger.

It is expected that, initially following the Merger, the business and operations of the Company will be continued substantially as they are currently being conducted. Stryker will continue to evaluate the business and operations of the Company during the pendency of the Offer and after the consummation of the Offer and the Merger and will take such actions as it deems appropriate under the circumstances then existing. Thereafter, Stryker intends to review such information as part of a comprehensive review of the Company’s business, operations, capitalization and management with a view to optimizing development of the Company’s potential in conjunction with Stryker’s existing business.

Except as set forth in this Item 4, neither Stryker nor Purchaser has any present plans or proposals which relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D.

References to, and descriptions of, the Merger Agreement and the Tender and Voting Agreements as set forth herein are qualified in their entirety by reference to the copies of the Merger Agreement and the Tender and Voting Agreements, respectively, copies of which are filed as Exhibits 1, 2 and 3, respectively, hereto and which are incorporated by reference in this Item 4 in their entirety where such references and descriptions appear.

Item 5.

Interest in Securities of the Issuer.

(a) and (b) For the purpose of Rule 13d-3 promulgated under the Exchange Act, Stryker and Purchaser, by reason of the execution and delivery of the Tender and Voting Agreements, may be deemed to have beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of the 10,231,348 Shares which are subject to the Tender and Voting Agreement, which represent approximately 13.28% of the Shares (based on the number of Shares outstanding as of May 13, 2011). Except as set forth in this Item 5, none of Purchaser, Stryker or, to their knowledge, any person listed in Schedule I hereto, owns beneficially any Shares.

With respect to the voting of the Shares, Stryker and Purchaser have the power to vote or cause the vote of the Shares in accordance with the terms of the Tender and Voting Agreements. Neither the filing of this Statement nor any of its contents shall be deemed to constitute an admission that Stryker or Purchaser is the beneficial owner of the Shares referred to in this Item 5 for purposes of Section 13(d) of the Exchange Act or for any other purpose, and such beneficial ownership is expressly disclaimed.


		Page 9 of 17

(c) Except for the execution and delivery of the Tender and Voting Agreements and the Merger Agreement, no transactions in the Shares were effected by Purchaser, Stryker or, to their knowledge, any person listed in Schedule I hereto, during the 60 days prior to the date hereof.

(d) Except for the agreements described in this Section 13D, to the knowledge of Stryker and Purchaser, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities of the Company reported herein.

ARTICLE I

THE OFFER

SECTION 1.01 The Offer. (a) Provided that this Agreement shall not have been terminated in accordance with Section 8.01 hereof, none of the events set forth on paragraphs (a) through (f) of Annex II shall have occurred and be continuing and the Company is prepared (in accordance with Section 1.02(c)) to file with the United States Securities and Exchange Commission (the “SEC”) the Schedule 14D-9 on the same date as Merger Sub commences the Offer, as promptly as practicable after the Agreement Date (and in any event no later than ten (10) Business Days after the date of initial public announcement of this Agreement, provided that the Company has so complied with the Pennsylvania Takeover Disclosure Law (to the extent actions are required to be taken by it) and is prepared to file with the SEC the Schedule 14D-9), Merger Sub shall, and Parent shall cause Merger Sub to, commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (including the rules and regulations promulgated thereunder, the “Exchange Act”)), the Offer to purchase all of the outstanding Shares at the Offer Price. The obligation of Merger Sub to accept for payment and pay for any Shares validly tendered and not properly withdrawn pursuant to the Offer shall be subject only to (i) the condition that there shall be validly tendered in accordance with the terms of the Offer, prior to the scheduled expiration of the Offer (as it may be extended from time to time hereunder), and not properly withdrawn, a number of Shares that, together with the Shares then directly or indirectly owned by Parent, represents at least a majority of all Fully Diluted Shares immediately prior to the Share Acceptance Time (without regard to Shares tendered pursuant to guaranteed delivery procedures that have not yet been delivered in satisfaction of such guarantee) (the “Minimum Condition”), and (ii) the conditions set forth in Annex II (together with the Minimum Condition, the “Offer Conditions”). Merger Sub, or Parent on behalf of Merger Sub, expressly reserves the right to waive, in its sole and absolute discretion, in whole or in part, any of the Offer Conditions and to make any change in the terms of or conditions to the Offer; provided, however, that unless otherwise provided by this Agreement or previously approved by the Company in writing (which approval may be granted or withheld by the Company in its sole and absolute discretion), (A) the Minimum Condition may not be waived or amended, (B) no change may be made that changes the form of consideration to be paid pursuant to the Offer, decreases the Offer Price or the number of Shares sought in the Offer, imposes conditions to the Offer in addition to those set forth in Annex II, or otherwise amends

or modifies the Offer in any manner materially adverse to the holders of Shares, and (C) the Offer may not be extended except as set forth in this Section 1.01. Subject to the terms and conditions of this Agreement, the Offer shall expire at midnight, New York City time, on the date that is twenty (20) Business Days (calculated as set forth in Rule 14d-1(g)(3) under the Exchange Act) following the commencement of the Offer (such time, the “Initial Expiration Date,” and such time, or such subsequent time to which the expiration of the Offer is extended in accordance with the terms of this Agreement, the “Expiration Date”). Notwithstanding anything in this Agreement to the contrary, unless this Agreement has been terminated in accordance with Section 8.01, (i) Merger Sub (or Parent on its behalf) may, in its sole and absolute discretion, without the consent of the Company, extend the Offer on one or more occasions, in consecutive increments of up to ten (10) Business Days each, for any period up to and including the Outside Date if on any then-scheduled Expiration Date any of the Offer Conditions has not been satisfied or waived in writing by Merger Sub (or Parent on its behalf), until such Expiration Date on which all Offer Conditions shall then be satisfied or, to the extent permitted, waived, (ii) Merger Sub (or Parent on its behalf) may, in its sole and absolute discretion, without the consent of the Company, extend the Offer for any period required by any rule, regulation, interpretation or position of the SEC or The NASDAQ Stock Market applicable to the Offer, (iii) except to the extent otherwise agreed in writing by the Company prior to any then-scheduled Expiration Date, Merger Sub (or Parent on its behalf) shall extend the Offer on one or more occasions, in consecutive increments of up to ten (10) Business Days each, up to and including the Outside Date, until the condition set forth in clause (ii) of the first paragraph of Annex II related to the HSR Act is satisfied or waived in writing by Merger Sub (or Parent on its behalf) and (iv) if on any scheduled Expiration Date, the Minimum Condition is not satisfied but all other Offer Conditions are satisfied, then Merger Sub (or Parent on its behalf) shall extend the Offer on a single occasion for a ten (10) Business Day period; provided, however, that Merger Sub shall not be required to extend the Offer pursuant to this sentence beyond the Outside Date. Notwithstanding anything in this Agreement to the contrary, Merger Sub (or Parent on its behalf) may increase the Offer Price and extend the Offer up to and including the Outside Date to the extent required by Law in connection with such increase, in each case, in its sole and absolute discretion and without the consent of the Company. Following the expiration of the Offer, Merger Sub (or Parent on its behalf) may, in its sole and absolute discretion, provide a subsequent offering period or one or more extensions thereof (a “Subsequent Offering Period”) in accordance with Rule 14d-11 under the Exchange Act, if, as of the commencement of such period, there shall not have been validly tendered (without regard to Shares tendered pursuant to guaranteed delivery procedures that have not yet been delivered in satisfaction of such guarantee), and not properly withdrawn pursuant to the Offer that number of Shares necessary to permit the Merger to be effected without a meeting of shareholders of the Company in accordance with Section 1924(b)(1)(ii) of the Pennsylvania Business Corporation Law (the “Business Corporation Law”). Subject to the foregoing, including the requirements of Rule 14d-11 under the Exchange Act, and upon the terms and subject to the conditions of the Offer, Merger Sub shall, and Parent shall cause Merger Sub to, accept for payment and pay for, as promptly as practicable (within the meaning of Rule 14e-1(c) of the Exchange Act), (1) after the Expiration Date, all Shares validly tendered and not properly withdrawn pursuant to the Offer and/or (2) all Shares validly tendered in any Subsequent Offering Period. The Company agrees that no Shares held by the Company or any of its Subsidiaries will be tendered pursuant to the Offer. Merger Sub shall be entitled to deduct and withhold from the consideration otherwise

payable pursuant to the Offer to any holder of Shares such amounts as Merger Sub 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 Laws relating to Taxes. If the payment of the Offer Price is to be made to a Person other than the Person in whose name the tendered Certificate is registered, it shall be a condition of payment that (x) the Certificate so tendered be properly endorsed or shall be otherwise in proper form for transfer, and (y) the Person requesting such payment shall have paid all transfer and other Taxes required by reason of the payment of the Offer Price to a Person other than the registered holder of the Certificate tendered, or required for any other reason relating to such holder or requesting Person, or shall have established to the satisfaction of Parent and Merger Sub that such Tax either has been paid or is not required to be paid. To the extent that amounts are so withheld and paid over to the appropriate Tax authority by Merger Sub, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding were made by Merger Sub. Merger Sub shall not terminate the Offer prior to any scheduled Expiration Date without the prior written consent of the Company (in its sole and absolute discretion), except if this Agreement is terminated pursuant to Section 8.01. If the Offer is terminated by Parent or Merger Sub, or this Agreement is terminated prior to the purchase of Shares in the Offer, Merger Sub shall promptly (within the meaning of Rule 14e-1(c) of the Exchange Act) return, and shall cause any depositary acting on behalf of Merger Sub to return, in accordance with applicable Law, all tendered Shares to the registered holders thereof.

(b) As promptly as practicable on the date of commencement of the Offer, Parent and Merger Sub shall (i) file a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, and supplements thereto and including exhibits thereto, the “Schedule TO”) with the SEC, which shall contain an Offer to Purchase reflecting the material terms and conditions of this Agreement, and a form of the letter of transmittal and other ancillary Offer documents and instruments, if any, in respect of the Offer (together with the Schedule TO, collectively, together with any amendments or supplements thereto, the “Offer Documents”), and (ii) subject to the Company’s compliance with Section 1.02(c), cause the Offer Documents to be disseminated to holders of Shares as and to the extent required by applicable Law. The Company shall promptly furnish to Parent and Merger Sub in writing all information concerning the Company that may be required by applicable Law for inclusion in the Offer Documents. Each of Parent, Merger Sub and the Company agrees promptly to correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and Parent and Merger Sub agree to take all steps necessary to cause the Schedule TO, as so corrected or supplemented, to be filed with the SEC and the Offer Documents, as so corrected or supplemented, to be disseminated to holders of Shares, in each case as, and to the extent, required by applicable Law. The Company and its counsel shall be given a reasonable opportunity to review the Schedule TO before it is filed with the SEC, and Parent and Merger Sub shall give due consideration to the reasonable additions, deletions or changes suggested thereto by the Company and its counsel. Parent and Merger Sub shall promptly provide the Company and its counsel with copies of any written comments or communications, and shall inform them of any oral comments or communications, that Parent, Merger Sub or their counsel may receive after the Agreement Date from the SEC or its staff with respect to the Offer Documents or otherwise with respect to the Offer promptly after receipt of those comments or other communications.

given a reasonable opportunity to review any written responses to such SEC comments and Parent and Merger Sub shall give due consideration to the reasonable additions, deletions or changes suggested thereto by the Company and its counsel.

ARTICLE III

EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS; EXCHANGE FUND; COMPANY EQUITY AWARDS

SECTION 3.01 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any Shares or any shares of capital stock of Parent or Merger Sub:

(a) Capital Stock of Merger Sub. Each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

(b) Cancellation of Treasury Stock, Parent-Owned Stock. Each Share that is directly owned of record by the Company, any wholly owned Subsidiary of the Company, by Parent or by Merger Sub immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c) Conversion of Company Common Stock. Each Share issued and outstanding immediately prior to the Effective Time (excluding Shares to be canceled in accordance with Section 3.01(b) and, except as provided in Section 3.01(d), the Appraisal Shares) shall be converted into the right to receive the Offer Price in cash, without interest (the “Merger Consideration”), payable net to the holder in cash, without interest and subject to any withholding of Taxes required by applicable Law. At the Effective Time, all such Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of (x) a certificate that immediately prior to the Effective Time represented any such Shares (each, a “Certificate”) or (y) any such uncertificated Shares (collectively, the “Uncertificated Shares”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration.

(d) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, Shares issued and outstanding immediately prior to the Effective Time that are held by any holder or beneficial owner who is entitled to demand and properly demands appraisal of such Shares (the “Appraisal Shares”) pursuant to, and who complies in all respects with, the provisions of Section 1930 of the Business Corporation Law, including compliance with Subchapter D of Chapter 15 of the Business Corporation Law (“Subchapter D”), as required by Section 1930 thereof, shall not be converted into the right to receive the Merger Consideration as provided in Section 3.01(c), but instead such holder or beneficial owner shall be entitled to payment of the fair value of such Appraisal Shares in accordance with Subchapter D. 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 or beneficial owner of 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 Subchapter D. Notwithstanding the foregoing, if any such holder or beneficial owner of Appraisal Shares shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Subchapter D or a court of competent jurisdiction shall determine that such holder or beneficial owner is not entitled to the relief provided by

Subchapter D, then the right of such holder or beneficial owner to be paid the fair value of such holder’s or beneficial owner’s Appraisal Shares under Subchapter D 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 3.01(c). The Company shall give prompt notice to Parent of any demands for appraisal of any Shares, withdrawals of such demands and any other instruments served pursuant to the Business Corporation Law received by the Company, and Parent shall have the right to direct all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Parent (in its sole and absolute discretion), make any payment with respect to, or settle or offer to settle, any such demands or approve any withdrawal of such demands. Notwithstanding anything to the contrary contained herein, no shareholder of the Company shall have any right to seek appraisal of Shares if such right is not expressly provided for as a result of the Merger under Subchapter D, including after giving full effect to the exemptions set forth in Section 1571(b) of the Business Corporation Law, and nothing in this Agreement is intended to confer any such right in circumstances where it is otherwise not so required. For the avoidance of doubt, no action has been taken by the Company Board to grant appraisal or dissenters rights in connection with the transactions contemplated by this Agreement or the Tender and Voting Agreements pursuant to Section 1571(c) of the Business Corporation Law.

(e) Adjustment Events. Without limiting any of the provisions of this Agreement, if, between the Agreement Date and the Effective Time, the Shares outstanding are changed into, or exchanged for, a different number or class of shares by reason of any stock dividend, split, combination, subdivision or reclassification of shares, reorganization, recapitalization or other similar transaction, then the Offer Price or Merger Consideration (as applicable) payable per Share and all Option Amounts shall be adjusted to the extent appropriate to fairly reflect the effects of such transaction.

SECTION 3.02 Exchange Fund.

(a) Paying Agent. Prior to the Closing Date, Parent shall appoint a bank or trust company reasonably acceptable to the Company to act as paying agent (the “Paying Agent”) for the payment of the Merger Consideration and, in connection therewith, shall enter into an agreement with the Paying Agent in a form reasonably acceptable to the Company. Parent shall deposit with the Paying Agent at the Effective Time cash in an amount sufficient to pay the aggregate Merger Consideration (such cash being hereinafter referred to as the “Exchange Fund”) as required to be paid pursuant to this Agreement.

(b) Exchange Procedures. As promptly as reasonably practicable after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of Shares (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Uncertificated Shares shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Paying Agent and which shall otherwise be in such form and have such other provisions as Parent may reasonably specify and the form of which the Company has approved (such approval not to be unreasonably withheld, delayed or conditioned)) and (ii) instructions for use in effecting the surrender of the Certificates and the transfer of Uncertificated Shares in exchange for the Merger Consideration. Each holder of

record of Shares shall, (x) upon surrender to the Paying Agent of such Certificate, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Paying Agent, or (y) upon receipt of a duly completed and validly executed letter of transmittal and such other documents as may reasonably be required by the Paying Agent in the case of a book-entry transfer of Uncertificated Shares, be entitled to receive in exchange therefor the amount of Merger Consideration that the number of Shares previously represented by such Certificate or the Uncertificated Shares, as applicable, shall have been converted into the right to receive pursuant to Section 3.01(c), and any Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Shares which are not registered in the transfer records of the Company, payment of the Merger Consideration may be made to a Person other than the Person in whose name the Certificate so surrendered is registered if (x) the Certificate so tendered is properly endorsed or is otherwise in proper form of transfer, and (y) the Person requesting such payment has paid all transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate tendered, or required for any other reason relating to such holder or requesting Person, or shall have established to the satisfaction of Parent and Merger Sub that such Tax either has been paid or is not required to be paid. Payment of the Merger Consideration with respect to Uncertificated Shares shall only be made to the Person in whose name such Uncertificated Shares are registered. Until surrendered or transferred as contemplated by this Section 3.02(b), each Certificate and each Uncertificated Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration that the holder thereof has the right to receive in respect of such Certificate or Uncertificated Shares pursuant to this Article III. No interest shall be paid or will accrue on any cash payable to holders of Certificates or Uncertificated Shares pursuant to the provisions of this Article III.

(c) No Further Ownership Rights in Company Common Stock. All cash paid upon the surrender of Certificates or the transfer of Uncertificated Shares in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares formerly represented by such Certificates or Uncertificated Shares, as applicable. At the Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates or Uncertificated Shares are presented to the Surviving Corporation for transfer, they shall be canceled against delivery of cash to the holder thereof as provided in this Article III.

(d) Termination of the Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Shares for six (6) months after the Effective Time shall be delivered to Parent, upon demand, and any holders of Shares who have not theretofore complied with this Article III shall thereafter, subject to Section 3.02(e), look only to Parent as general creditors thereof with respect to the payment of their claims for the Merger Consideration that may be payable to such holders as determined pursuant to the provisions of this Article III.

(e) No Liability. None of Parent, Merger Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any Person in respect of any cash from the Exchange Fund delivered to a public official in compliance with any applicable state, Federal or

other abandoned property, escheat or similar Law. If any Certificate or Uncertificated Shares shall not have been surrendered prior to the date on which the related Merger Consideration would escheat to or become the property of any Governmental Entity, any such Merger Consideration shall, to the extent permitted by applicable Law, immediately prior to such time become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(f) Investment of Exchange Fund. The Paying Agent shall invest or hold the cash in the Exchange Fund as directed by Parent. Any interest and other income resulting from such investments shall be paid solely to Parent. Nothing contained herein and no investment losses resulting from investment of the Exchange Fund shall diminish the rights of any holder of Shares to receive the Merger Consideration as provided herein and in the event the funds on deposit with the Paying Agent are insufficient to pay the aggregate Merger Consideration, Parent shall deposit, or cause to be deposited, with the Paying Agent such additional funds to ensure that the Paying Agent has funds sufficient to pay the aggregate Merger Consideration.

(g) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact in form and substance reasonably satisfactory to Parent or the Paying Agent by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Paying Agent, the posting by such Person of a bond or surety in such reasonable amount as Parent or the Paying Agent may direct as indemnity against any claim that may be made against Parent, Merger Sub, the Surviving Corporation or the Paying Agent with respect to such Certificate, the Paying Agent shall deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto.

(h) Withholding Rights. Parent, the Surviving Corporation or the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares, any holder of a Company Stock Option or any holder of Company Restricted Stock such amounts as Parent, the Surviving Corporation or the Paying Agent are required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (including the rules and regulations promulgated thereunder, the “Code”), or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares, the holder of the Company Stock Option or the holder of Company Restricted Stock, as the case may be, in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Paying Agent.

SECTION 3.03 Company Stock Plans.

(a) Company Equity Awards. As soon as reasonably practicable following the Agreement Date, and in any event prior to the Effective Time, the Company Board (or, if appropriate, any committee administering any Company Stock Plan) shall adopt appropriate resolutions and take all other actions as may be required, including obtaining any consents, to provide that, immediately prior to the Effective Time, (i) each unexercised Company Stock Option that is outstanding immediately prior to the Effective Time, whether or not vested, shall

be canceled, and, in exchange therefor, each former holder of each such canceled Company Stock Option shall be entitled to receive, in consideration of the cancellation of such Company Stock Option and in settlement therefor, an amount in cash (without interest and subject to any applicable withholding of Taxes required by applicable Law in accordance with Section 3.02(h)) equal to (A) the excess, if any, of (1) the Merger Consideration over (2) the exercise price per share of Company Common Stock previously subject to such Company Stock Option, multiplied by (B) the total number of Shares previously subject to such Company Stock Option, whether or not vested (such amount, the “Option Amount”), and (ii) each share of Company Restricted Stock shall vest in full in accordance with the terms of the applicable Company Stock Plan and the Shares issued thereunder shall be canceled at the Effective Time and converted into the right to receive the Merger Consideration pursuant to Section 3.01(c). All amounts payable pursuant to this Section 3.03 shall be paid as promptly as practicable following the Effective Time, without interest, and Parent shall cause the Surviving Corporation to make such payments as promptly as practicable after the Effective Time in accordance with the foregoing and the terms of the Company Stock Options or the applicable Company Stock Plans pursuant to which they were issued (as modified pursuant hereto). Prior to the Share Acceptance Time, except as otherwise agreed to by the parties, the Company shall take such action such that the Company Stock Plans shall terminate as of the Effective Time.

(b) Employee Stock Purchase Plan. Between the Agreement Date and the Effective Time, (A) participation in the ESPP shall be limited to those employees who are participants on the Agreement Date; (B) ESPP participants may not increase the rate of their payroll deductions or purchase elections from those in effect on the Agreement Date; (C) no Purchase Period (as defined in the ESPP) shall be commenced (provided, however, except as otherwise provided herein, ESPP participants shall be entitled to make elections in accordance with the ESPP with respect to any Purchase Period which has commenced as of the Agreement Date); (D) if, with respect to a Purchase Period in effect on the Agreement Date, the Effective Time occurs prior to the Purchase Date (as defined in the ESPP) for such Purchase Period, upon the Effective Time, each purchase right under the ESPP outstanding immediately prior to the Effective Time shall be used to purchase from the Company whole shares of Company Common Stock (subject to the provisions of the ESPP regarding the maximum number and value of shares purchasable per participant) at the applicable price determined under the terms of the ESPP or the then outstanding Purchase Period using such date as the final Purchase Date for such Purchase Period, and any remaining accumulated but unused payroll deductions shall be distributed to the relevant participants without interest as promptly as practicable following the Effective Time; and (E) the ESPP shall terminate, effective upon the earlier of the Purchase Date for the Purchase Period in effect on the Agreement Date and the Effective Time.

SECTION 3.04 Company Warrants. No Company Warrants, whether vested or unvested, shall be assumed by Parent, Merger Sub or the Surviving Corporation in the Merger. At the Effective Time, each unexercised Company Warrant that is outstanding immediately prior to the Effective Time, whether or not vested, shall be canceled, and, in exchange therefor, each former holder of each such canceled Company Warrant shall be entitled to receive, in consideration of the cancellation of such Company Warrant and in settlement therefor, an amount in cash (without interest and subject to any applicable withholding of Taxes required by applicable Law in accordance with Section 3.02(h)) equal to (A) the excess, if any, of (1) the Merger Consideration over (2) the exercise price per share of Company Common Stock

previously subject to such Company Warrant, multiplied by (B) the total number of Shares previously subject to such Company Stock Warrant. All amounts payable pursuant to this Section 3.04 shall be paid as promptly as practicable following the Effective Time, without interest, and Parent shall cause the Surviving Corporation to make such payments as promptly as practicable after the Effective Time in accordance with the foregoing and the terms of the Company Warrant, subject to the receipt of a duly completed and validly executed letter of transmittal, substantially in the same form as the letter of transmittal contemplated by Section 3.02(b) and such other documents as may reasonably be required by the Parent or the Surviving Corporation.

(vii) There are no actions, suits, proceedings, claims, arbitrations, audits or investigations that are pending or, to the Knowledge of the Company, threatened with respect to any Company Benefit Plan, other than routine claims for benefits.

(viii) Except as set forth in Section 4.01(n)(viii) of the Company Disclosure Schedule, the negotiation or consummation of the transactions contemplated by this Agreement will not, either alone or in combination with another event (including as a result of termination of employment on or following the Closing), (A) entitle any current or former employee or officer of the Company or any of its Subsidiaries to severance pay, or any other payment from the Company or any of its Subsidiaries, or (B) accelerate the time of payment or vesting, cause a lapse of repurchase rights, trigger any payment or funding (through a grantor trust or otherwise) of, or compensation or benefits under, increase the amount payable or trigger any other obligation pursuant to any Company Benefit Plan or increase the amount of compensation due any such employee or officer. Except as set forth in Section 4.01(n)(viii) of the Company Disclosure Schedule, there is no Company Benefit Plan or other plan, Contract, program, fund or arrangement of any kind, that, individually or collectively, has given rise or could give rise to the payment of any amount that would not be deductible pursuant to (A) Sections 280G of the Code (determined without regard to Section 280G(b)(4) of the Code) or (B) Section 162(m) of the Code.

(ix) Except as set forth in Section 4.01(n)(ix) of the Company Disclosure Schedule, no Company Benefit Plan covers employees of the Company or any of its Subsidiaries outside of the United States.

(x) Each Company Benefit Plan that is a “nonqualified deferred compensation plan” (as defined in Section 409A(d)(1) of the Code) has (i) been maintained and operated since January 1, 2005 in good faith compliance with Section 409A of the Code and all applicable Internal Revenue Service guidance promulgated thereunder so as to avoid any Tax, penalty or interest under Section 409A of the Code and, as to any such plan in existence prior to January 1, 2005, has not been “materially modified” (within the meaning of Internal Revenue Service Notice 2005-1) at any time after October 3, 2004 or has been amended in a manner that conforms with the requirements of Section 409A of the Code, and (ii) since January 1, 2009, been in documentary and operational compliance with Section 409A of the Code and all applicable Internal Revenue Service guidance promulgated thereunder except, in each case, for noncompliance that would not result in material liability to the Company or an employee of the Company.

(xi) Each plan, arrangement, agreement or contract that would otherwise meet the definition of a “Company Benefit Plan” but which is subject to any Law other than U.S. federal, state or local Law (“Foreign Plan”) has been administered in compliance in all material respects with its terms and operated in compliance in all material respects with applicable Laws. Each Foreign Plan required to be registered or approved by a non-U.S. governmental entity has been registered or approved and has been maintained in good standing with applicable regulatory authorities, and no event has occurred since the date of the most recent approval or application therefor relating to any such Foreign Plan that could reasonably be expected to materially affect any such approval relating thereto or increase the costs relating thereto in a manner material to the Company and its Subsidiaries as a whole. To the Company’s Knowledge, each Foreign Plan is fully funded or fully insured on an ongoing and termination or solvency basis (determined using reasonable actuarial assumptions) in compliance with applicable Law, and the fair market value of the assets held under each Foreign Plan that is a pension plan or that is funded on an actuarial basis is sufficient so as to permit a termination of each such Foreign Plan, in full compliance with applicable Law (to the extent such a fully funded or fully insured Foreign Plan may be terminated in accordance with applicable Law), immediately after the Closing Date without Parent, the Surviving Corporation or any of their Affiliates being required to make additional contributions to such Foreign Plan (or related trust) or to incur any liability with respect to the funding or payment of benefits under such Foreign Plan. The parties acknowledge and agree that this Section 4.01(n)(xi) contains the only representations and warranties in this Agreement applicable to any Foreign Plans.

(xii) The term “Company Benefit Plan” means each (A) employment, consulting, indemnification, severance, salary continuation, change in control or termination agreement or arrangement between the Company or any of its Subsidiaries, on the one hand, and any current or former employee, officer or director of the Company or any of its Subsidiaries, on the other hand, other than any agreement or arrangement mandated by applicable Law, and (B) bonus, pension, profit sharing, deferred compensation, incentive compensation, stock ownership, stock purchase, stock appreciation, stock option, phantom stock, restricted stock or other equity-based compensation, retirement, savings, workers’ compensation, vacation, paid time off, perquisite, fringe benefit, indemnification, disability, death benefit, hospitalization, medical or other employee benefits plan, policy, program, arrangement or understanding, in each case sponsored, maintained or contributed to, or required to be sponsored, maintained or contributed to, by the Company or any of its Subsidiaries, whether or not funded, in respect of any present or former employees, directors, or officers of the Company or any of its Subsidiaries, which are sponsored or maintained by the Company or any of its Subsidiaries or with respect to which the Company or any of its Subsidiaries is obligated to make payments, transfers, or contributions, or under which any of them has or would be reasonably likely to have any liability for premiums or benefits for the benefit of any present or former employees or directors of the Company or any of its Subsidiaries; provided, however, the foregoing definition of “Company Benefit Plan” shall only be deemed to apply with respect to the former employees, directors and/or officers of the Company and/or its Subsidiaries to the extent the Company and/or its Subsidiaries has any continuing obligations.

(o) Taxes.

(i) 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 and were prepared in material compliance with all Laws. All material Taxes required to be paid by the Company and each of its Subsidiaries have been paid (regardless of having been shown as due on any such return), except for those Taxes for which adequate reserves have been established in the financial statements included in the Filed SEC Documents in accordance with GAAP. There are no material Liens related to Taxes on any assets of the Company or any of its Subsidiaries other than Liens relating to Taxes not yet due and payable.

(ii) The Company and each of its Subsidiaries have withheld all material federal, state, local and foreign Taxes required to be withheld in connection with amounts owing to any employee, independent contractor, creditor, shareholder or any other third party. Neither the Company nor any of its Subsidiaries has received any written notice of any material Tax deficiency outstanding, proposed or assessed against the Company or any of its Subsidiaries. Except as set forth on Section 4.01(o)(ii) of the Company Disclosure Schedule, neither the Company nor any of its Subsidiaries has received any written notice of any audit examination, deficiency, refund litigation or proposed adjustment with respect to any Tax Return of the Company or any of its Subsidiaries.

(iii) 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 Person other than the Company or any Subsidiary, except for such agreements solely among the Company and its Subsidiaries. Neither the Company nor any of its Subsidiaries is liable for the Taxes of any Person (other than the Company or any Subsidiary) under Treasury Regulation § 1.1502-6 (or any similar provision of state, local or foreign Law) as a transferee or successor, by Contract, by operation of Law or otherwise.

The Company has disclosed on its federal income Tax Return all positions taken therein that could give rise to substantial understatement of federal income Taxes within the meaning of Section 6662 of the Code.

(vii) No Governmental Entity in a jurisdiction where the Company or a Subsidiary of the Company does not file Tax Returns has ever claimed that the Company or that Subsidiary, as the case may be, is subject to Liability for any Taxes by that jurisdiction or is required to file a Tax Return in that jurisdiction.

(viii) The unpaid Taxes of the Company and its Subsidiaries (A) did not, as of March 31, 2011, exceed the reserve for Tax Liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the face of the audited consolidated balance sheet of the Company as of December 31, 2010 included in the Filed SEC Documents (rather than in any notes thereto) and (B) do not exceed that reserve as adjusted for the passage of time through the Effective Time in accordance with the past custom and practice of the Company and its Subsidiaries in filing their Tax Returns. Since December 31, 2010, neither the Company nor any of its Subsidiaries has incurred any Liability for Taxes arising from extraordinary gains or losses, as that term is used in GAAP, outside the ordinary course of business consistent with past custom and practice.

(ix) There are no agreements or waivers extending the statutory period of limitation applicable to any Taxes of the Company or any Subsidiary for any period. There is no power of attorney given by or binding upon the Company or any Subsidiary with respect to Taxes for any period for which the statute of limitations (including any waivers or extensions) has not yet expired.

The Company is not and has not been a “United States real property holding corporation” (as defined in Section 897(c)(2) of the Code) during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code, and the shares of Company Common

Stock are “regularly traded on an established securities market” for purposes of Section 1445(b)(6) of the Code and Treasury Regulation Section 1.1445-2(c)(2).

(xii) Neither the Company nor any Subsidiary of the Company has been a “controlled corporation” or a “distributing corporation” in any distribution of stock qualifying for tax-free treatment under Section 355 or Section 361 of the Code occurring during the two-year period ending on the date hereof.

Furthermore, (a) neither the Company nor any of its Subsidiaries has received any written notice of cancellation, lapse, invalidation or non-renewal of any such insurance policies, other than notices received in connection with renewals in the ordinary course of business consistent with past practice, (b) there is no Claim pending under any of such policies or arrangements as to which coverage has been questioned, denied or disputed by the underwriters of such policies or arrangements, (c) neither the Company nor any of its Subsidiaries has received any notice from any of its insurance carriers that any insurance premiums will be increased in the future or that any insurance coverage presently provided for will not be available to the Company or any of its Subsidiaries in the future on substantially the same terms as now in effect and (d) none of such policies or arrangements provides for any retrospective premium adjustment, experienced-based liability or loss sharing arrangement affecting the Company or any of its Subsidiaries.

(s) Title to Property.

Except as set forth on Section 4.01(s) of the Company Disclosure Schedule, no condition exists that with notice or lapse of time or both would constitute a default under any of the Real Property Leases by the Company or any Subsidiary, and to the Company’s Knowledge, no other party to any of the Real Property Leases is in breach or default thereunder.

SECTION 5.02 Non-Solicitation.

(a) Subject to Section 5.02(b):

(i) The Company shall not and shall cause its Subsidiaries and its and their respective Representatives not to, directly or indirectly, from and after the Agreement Date until the earlier of the Director Appointment Date or the termination of this Agreement in accordance with Section 8.01, (A) solicit, initiate, encourage (including by way of providing information) or induce the submission or announcement of any inquiries, proposals or offers or any other efforts or attempts that constitute, or could reasonably be expected to lead to, a Takeover Proposal, (B) enter into, continue, participate or engage in any discussions or negotiations with, or furnish any information to, any Person with respect to a Takeover Proposal or (C) otherwise cooperate with or assist or participate in, or facilitate or take any action that could reasonably be expected to facilitate, any such inquiries, proposals, offers, discussions or negotiations. For purposes of this Agreement:

(A) the term “Acquisition Transaction” means any transaction or series of transactions, directly or indirectly, (1) involving any exchange, lease, sale, disposition, acquisition, transfer, purchase, or exclusive license of all or substantially all of the Company’s rights with respect to assets or businesses of the Company (including capital stock of the Subsidiaries of the Company) or any Subsidiary of the Company representing ten percent (10%) or more of the assets (measured by fair market value) or net revenues of the Company and its Subsidiaries, taken as a whole, (2) that, if consummated, would result in any Person or group beneficially owning, directly or indirectly, or having the right to acquire, equity interests representing ten percent (10%) of the outstanding shares of Company Common Stock or of the voting power of the Company’s capital stock, (3) involving any merger, consolidation, business combination, recapitalization, liquidation, dissolution, binding share exchange or similar transaction involving the Company pursuant to which any Person or group (or the shareholders of any Person) would own, directly or indirectly, ten percent (10%) or more of any class of equity securities of the Company or of the surviving entity in a merger or the resulting direct or indirect parent of the Company or such surviving entity, (4) the issuance or sale by the Company or its Subsidiaries (including by way of merger, consolidation, business combination, share exchange, joint venture or similar transaction) of equity interests representing ten percent (10%) or more of the voting power of the Company, or (5) any combination of the foregoing, other than, in each case, the transactions contemplated by this Agreement; and

(B) the term “Takeover Proposal” means any inquiry, proposal or offer (whether or not in writing) from any Person or group relating to any Acquisition Transaction.

(ii) The Company shall immediately cease and cause to be terminated any solicitation, discussion or negotiation with any Person conducted heretofore by the Company, its Subsidiaries or any of their respective Representatives with respect to any actual or potential Acquisition Transaction and shall use its reasonable best efforts to cause any such Person to return or destroy all confidential information provided by or on behalf of the Company or any of its Subsidiaries to such Person or its Representatives.

(b) Notwithstanding anything to the contrary contained in Section 5.02(a), if at any time from and after the Agreement Date and prior to the Share Acceptance Time, (i) the Company has received a bona fide written Takeover Proposal from a third party, (ii) the Company is not in material breach or violation of the terms of this Section 5.02, (iii) to the extent the Company is prohibited as a result of a confidentiality, non-disclosure or similar Contract as in effect on the Agreement Date from disclosing to Parent or its Representatives any discussions or negotiations between the Company or its Representatives and such Person, or any information that may be exchanged in connection with such discussions or negotiations, in each case as required by the provisions of this Agreement, such Person has provided the Company with a written acknowledgement that such discussions, negotiations and the information exchanged in connection therewith may be disclosed to Parent and its Representatives to the extent required by this Agreement and (iv) the Company Board determines in good faith (after consultation with its outside legal counsel and financial advisor) that (A) such Takeover Proposal constitutes or could reasonably be expected to lead to a Superior Proposal and (B) that the failure to take such action would be inconsistent with its fiduciary obligations to the Company’s shareholders under applicable Law, then the Company may (x) furnish information with respect to the Company and its Subsidiaries to the Person making such Takeover Proposal pursuant to an Acceptable Confidentiality Agreement (a copy of which shall be provided by the Company to Parent promptly after its execution or, if executed prior to the Agreement Date, prior to entering into any discussions or negotiations or prior to furnishing any information hereunder), provided that the Company shall provide to Parent any nonpublic information regarding the Company or any of its Subsidiaries provided to any other Person which was not previously provided to Parent (such additional information to be provided prior to the time such information is provided to such other Person) and (y) engage in discussions or negotiations with the Person making such Takeover Proposal regarding such Takeover Proposal. As used herein, the term “Superior Proposal” means any bona fide written Takeover Proposal (provided that for purposes of the definition of “Superior Proposal”, the references to ten percent (10%) in the definition of Acquisition Transaction shall be deemed to be references to more than fifty percent (50%)), which was not solicited after the Agreement Date in material breach of this Section 5.02, was made after the Agreement Date and did not result from a material breach of this Section 5.02, and which the Company Board determines in good faith (after consultation with its outside legal counsel and financial advisor), taking into account the various legal, financial, regulatory and other aspects of the proposal, including the financing terms thereof, and the Person making such proposal, if accepted, is reasonably capable of being consummated in a timely fashion on the

terms proposed, and if consummated would result in a transaction that is more favorable to the Company’s shareholders, from a financial point of view, than the Offer and the Merger (after taking into account, if applicable, any proposal by Parent to amend, or make adjustments to, the terms and conditions of this Agreement pursuant to Section 5.02(d) or otherwise). The Company shall, and shall cause its Subsidiaries to, enforce the provisions of any standstill, confidentiality agreement or similar agreement to which the Company or any of its Subsidiaries is a party and that relates to any potential Acquisition Transaction (including obtaining injunctions to prevent any breaches of such agreements and to enforce specifically the terms and provisions thereof in any court or other tribunal having jurisdiction). Effective as of the Company’s taking any action described in clauses (x) or (y) above or upon a determination by the Company Board that a Takeover Proposal constitutes a Superior Proposal, the standstill and any other similar provisions in the Confidentiality Agreement shall become null and void and of no further force and effect to the extent necessary to permit Parent and Merger Sub to make proposals to the Company regarding adjustments to the terms and conditions of this Agreement.

(c) From and after the Agreement Date until the Director Appointment Date, the Company shall as promptly as practicable (and in any event within twenty four (24) hours and prior to providing any such Person with any non-public information) notify Parent in writing in the event that the Company or any of its Subsidiaries or Representatives receives any Takeover Proposal from any Person or group or any request for information or inquiry that contemplates or could reasonably be expected to lead to a Takeover Proposal, which notice shall set forth the material terms and conditions of any such Takeover Proposal, request or inquiry and the identity of the Person making such Takeover Proposal, request or inquiry. The Company shall keep Parent fully informed in writing as promptly as practicable (and in any event within twenty four (24) hours) of any material change in the status of or material terms and conditions (including all material amendments or proposed material amendments conveyed to the Company or its Representatives) of any such Takeover Proposal, request or inquiry and shall, promptly upon receipt or delivery thereof, provide Parent (or its outside legal counsel) with copies of all documents and written communications relating to any such Takeover Proposal, request or inquiry exchanged between the Company or any of its Representatives, on the one hand, and the Person making a Takeover Proposal or any of its Representatives, on the other hand. The Company shall provide Parent with at least forty-eight (48) hours prior notice of a meeting of the Company Board (or such lesser notice as is provided to the members of the Company Board) at which the Company Board is reasonably expected to consider any Takeover Proposal. The Company shall not, and shall cause its Subsidiaries not to, enter into any Contract with any Person subsequent to the Agreement Date that prohibits, or which contains any provision that adversely affects the rights of the Company or any of its Subsidiaries upon, compliance with any of the provisions of this Agreement.

(d) From and after the Agreement Date until the Director Appointment Date, neither the Company Board nor any committee thereof shall (i) approve or recommend, or resolve to or publicly propose to approve or recommend, any Takeover Proposal, (ii) withdraw, change, amend, modify or qualify in a manner adverse to Parent or Merger Sub, or resolve to or publicly propose to withdraw, modify or qualify in a manner adverse to Parent or Merger Sub, or take any action or make any statement in connection with the transactions contemplated by this

Agreement that is inconsistent with, the Board Recommendation (any action or failure to act set forth in the foregoing clauses (i) or (ii), an “Adverse Recommendation Change”) or (iii) approve or recommend, or resolve to or propose publicly to approve, recommend or permit the Company or any of its Affiliates to enter into, any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract constituting or related to, or which is intended to or could reasonably be expected to lead to, any Takeover Proposal or requiring, or reasonably expected to cause, the Company to abandon, terminate, delay or fail to consummate, or that would otherwise impede, interfere or be inconsistent with, the Offer, the Merger or any of the other transactions contemplated by this Agreement or requiring, or reasonably expected to cause, the Company to fail to comply with this Agreement (other than an Acceptable Confidentiality Agreement referred to in, and in compliance with, Section 5.02(b)). Notwithstanding the foregoing or anything else in this Agreement to the contrary, if at any time prior to the Director Appointment Date the Company receives a bona fide written Takeover Proposal which the Company Board determines in good faith (after consultation with its outside legal counsel and financial advisor) constitutes a Superior Proposal, the Company Board may at any time prior to the Share Acceptance Time, if it determines in good faith (after consultation with its outside legal counsel) that the failure to take such action would be inconsistent with its fiduciary obligations to the Company’s shareholders under applicable Law, (x) effect an Adverse Recommendation Change with respect to such Superior Proposal and/or (y) terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing clause (y), and any purported termination pursuant to the foregoing clause (y) shall be void and of no force or effect, unless in advance of or concurrently with such termination the Company pays the Company Termination Fee and otherwise complies with the provisions of Section 8.01(f) and Section 6.08; and provided further that the Company Board may not effect an Adverse Recommendation Change pursuant to the foregoing clause (x) or terminate this Agreement pursuant to the foregoing clause (y) unless (A) the Company has materially complied with all of its obligations pursuant to this Section 5.02, and (B):

(i) the Company shall have provided prior written notice to Parent, at least five (5) Business Days in advance (the “Notice Period”), of its intention to take such action with respect to such Superior Proposal, which notice shall specify the material terms and conditions of such Superior Proposal (including the identity of the party making such Superior Proposal) and a copy of the proposed definitive agreement for any such Superior Proposal in the form to be entered into; and

(ii) prior to effecting such Adverse Recommendation Change or terminating this Agreement to enter into a definitive agreement with respect such Superior Proposal, the Company shall, and shall cause its Representatives to, during the Notice Period, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Takeover Proposal ceases to constitute a Superior Proposal.

In the event of any amendment to the financial terms or any other material revisions to the Superior Proposal, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 5.02(d) with respect to such new written notice. If Parent makes adjustments to the terms and conditions of this Agreement so that any Takeover Proposal ceases to constitute a Superior Proposal, the Company shall be entitled to notify the third party (which made the Takeover Proposal) thereof.

(e) Notwithstanding anything to the contrary contained in this Section 5.02, if the Company Board determines in good faith (after consultation with its outside legal counsel) that the failure to take such action would be inconsistent with its fiduciary duties to the shareholders of the Company under applicable Law, the Company Board may at any time prior to the Director Appointment Date and solely in response to an Intervening Event (x) effect an Adverse Recommendation Change with respect to such Intervening Event; provided, however, that the Company Board may not effect an Adverse Recommendation Change unless the Company shall have provided prior written notice to Parent, at least five (5) Business Days in advance of its intention to take such action, which notice shall specify the facts, circumstances and other conditions giving rise thereto, and prior to effecting such Adverse Recommendation Change, the Company shall, and shall cause its Representatives to, during such five (5) Business Day period, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that an Adverse Recommendation Change is no longer necessary.

(f) Nothing contained in this Section 5.02 or elsewhere in this Agreement shall prohibit the Company from (i) taking and disclosing to its shareholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or (ii) making any disclosure to its shareholders if the Company Board determines in good faith (after consultation with its outside legal counsel) that failure to do so would be inconsistent with its fiduciary duties to the shareholders of the Company under applicable Law, it being understood, however, that (x) nothing in this Section 5.02(f) shall be deemed to permit the Company Board to make an Adverse Recommendation Change except to the extent permitted by Section 5.02(d) or Section 5.02(e) and (y) if any disclosure under this Section 5.02(f) (other than issuance by the Company of a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) does not expressly reaffirm the Board Recommendation, such disclosure shall be deemed a Adverse Recommendation Change.

ARTICLE VI

The Proxy Statement shall (i) include a description of the Board Actions and include the Fairness Opinion and the information with respect to such opinion required to be disclosed by Item 1015(b) of Regulation M-A under the Exchange Act and (ii) to the extent that no Adverse Recommendation Change shall have occurred in accordance with Section 5.02(d) or Section 5.02(e) and not been withdrawn, shall reflect the Board Recommendation. Parent shall cooperate with the Company in the preparation of the preliminary Proxy Statement and the definitive Proxy Statement and shall furnish to the Company the information relating to it and Merger Sub required by the Exchange Act. The Company shall use its reasonable best efforts, after consultation with Parent, to respond as promptly as practicable to any comments of the SEC and to cause the Proxy Statement in definitive form to be mailed to the Company’s shareholders at the earliest practicable time. Each of the Company, Parent and Merger Sub shall promptly correct any information provided by it for use in the Proxy Statement if and to the extent that it shall have become false or misleading in any material respect. The Company agrees to take all steps necessary to cause the Proxy Statement as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case as, and to the extent, required by applicable Law. The Company shall promptly provide Parent and its counsel with copies of any written comments or communications, and shall inform them of any oral comments or communications, that the Company or its counsel may receive from the SEC or its staff (including any request by the SEC or its staff for any amendments or supplements to the preliminary Proxy Statement or

the definitive Proxy Statement), and the Company and Parent shall cooperate in filing with the SEC or its staff, and if required, the Company shall mail to its shareholders, as promptly as reasonably practicable, such amendment or supplement. Parent and its counsel shall be given a reasonable opportunity to review any written responses to such SEC comments and the Company shall give due consideration to the reasonable additions, deletions or changes suggested thereto by Parent and its counsel.

SECTION 6.02 Access to Information; Confidentiality. The Company shall, and shall cause each Subsidiary to, afford to Parent, and to Parent’s officers, employees, accountants, counsel, consultants, financial advisors and other Representatives, access at reasonable times upon reasonable prior notice during the period prior to the Effective Time to all of its and its Subsidiaries’ facilities, properties, books and records (including stock records and access to its transfer agent) and to those officers, employees and agents of the Company to whom Parent reasonably requests access (including the reasonable opportunity to communicate with the employees of the Company or its Subsidiaries that Parent expects to retain with respect to the benefits and compensation of such employees following the Share Acceptance Time), and, during such period, the Company shall furnish, as promptly as practicable, to Parent all information concerning its and its Subsidiaries’ business, finances, operations, properties and personnel as Parent may reasonably request, and Parent shall be entitled to undertake environmental investigations at any of the properties owned, operated or leased by the Company or any of its Subsidiaries (so long as such access (including any environmental investigation) does not unreasonably interfere with the operations of the Company or its Subsidiaries). Notwithstanding the foregoing, neither the Company nor any of its Subsidiaries shall be required to provide access to or disclose information or documentation (a) where such access or disclosure would contravene any Law or (b) relating to (y) the consideration, negotiation and performance of this Agreement and related agreements and (z) except as required by Section 5.02, any Takeover Proposal made after the execution of this Agreement (provided that, in the case of clause (a), the Company shall use its reasonable best efforts to put in place an arrangement to permit such disclosure without violating such Law). Except for disclosures expressly permitted by the terms of the confidentiality letter agreement dated as of January 18, 2011 between Parent and the Company (as it may be amended from time to time, the “Confidentiality Agreement”), Parent shall hold, and shall cause its respective officers, employees, accountants, counsel, financial advisors and other Representatives to hold, all information received from the Company or its Representatives, directly or indirectly, in confidence in accordance with the Confidentiality Agreement. No investigation by Parent or any of its Representatives and no other receipt of information by Parent or any of its Representatives shall operate as a waiver or otherwise affect any representation, warranty, obligation, covenant or other agreement of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

SECTION 6.03 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each of the Company, Parent and Merger Sub shall use its reasonable best efforts to cause the Merger and the other transactions contemplated by this Agreement to be consummated as promptly as reasonably practicable on the terms and subject to the conditions hereof. Without limiting the foregoing, (i) each of the Company, Parent and Merger Sub shall use its reasonable best efforts: (A) to make promptly any required submissions under the HSR Act with respect to this Agreement, the Merger and the other transactions contemplated hereby; (B) to furnish information required in connection with such submissions under the HSR Act; (C) to keep the other parties reasonably informed with respect to the status of any such submissions under the HSR Act, including with respect to: (1) the receipt of any non-action, action, clearance, consent, approval or waiver, (2) the expiration of any waiting period, (3) the commencement or proposed or threatened commencement of any investigation, litigation or administrative or judicial action or proceeding under the HSR Act, the Federal Trade Commission Act (the “FTC Act”), the Clayton Antitrust Act (the “Clayton Act”) or the Sherman Antitrust Act (the “Sherman Act”) (HSR Act, FTC Act, Clayton Act and Sherman Act, collectively “Antitrust Law”) and (4) the nature and status of any objections raised or proposed or threatened to be raised under the HSR Act, FTC Act, Clayton Act or Sherman Act with respect to this Agreement, the Merger or the other transactions contemplated hereby; and (D) to obtain all necessary actions or non-actions, waivers, consents, clearances and approvals from any Governmental Entity and (ii) Parent, Merger Sub and the Company shall: (A) cooperate with one another in promptly determining whether any filings are required to be made or consents, approvals, permits or authorizations are required to be obtained under any other supranational, national, federal, state, foreign or local Law or regulation or whether any consents, approvals or waivers are required to be obtained from other parties to loan agreements or other Contracts related to the Company’s business in connection with this Agreement, the Merger or the consummation of the other transactions contemplated hereby; (B) cooperate with one another in promptly making any such filings, furnishing information required in connection therewith and seeking to obtain timely any such consents, permits, authorizations, approvals or waivers; and (C) not to enter into any transaction prior to the Share Acceptance Time that would reasonably be expected to materially increase the risk of not obtaining the applicable clearance, approval or waiver under the Antitrust Laws with respect to the transactions contemplated by this Agreement.

(b) The Company, Parent and Merger Sub shall: (i) promptly notify the others of, and if in writing, furnish the outside legal counsel for the others with copies of (or, in the case of oral communications, advise the others of the contents of) any communication to such Person from a Governmental Entity and permit the others to review and discuss in advance (and to consider in good faith any comments made by the others in relation to) any proposed written communication to a Governmental Entity; provided that materials may be redacted (x) to remove references concerning the valuation of the Company, (y) as necessary to comply with contractual arrangements, and (z) as necessary to address reasonable attorney-client or other privilege or confidentiality concerns; and (ii) keep the others reasonably informed of any developments, meetings or discussions with any Governmental Entity in respect of any filings, investigation, or inquiry concerning the Merger. No party to this Agreement shall participate in or agree to

participate in any substantive meeting, telephone call or discussion with any Governmental Entity in respect of any filings, investigation (including any settlement of the investigation), litigation or other inquiry relating to such matters unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate in such meeting, telephone call or discussion. The parties to this Agreement will coordinate and cooperate fully with each other in exchanging such information and providing such assistance as the other party may reasonably request in connection with the foregoing and in seeking early termination of any applicable waiting periods, including under the HSR Act.

(c) In furtherance and not in limitation of the foregoing, if any objections are asserted with respect to the transactions contemplated hereby under the HSR Act, FTC Act, Clayton Act, Sherman Act or if any investigation, litigation or other administrative or judicial action or proceeding is commenced or proposed or threatened to be commenced challenging any of the transactions contemplated hereby as violative of the HSR Act, FTC Act, Clayton Act or Sherman Act or which would otherwise prevent, materially impede or materially delay the consummation of the transactions contemplated hereby, each of the Company, Parent and Merger Sub shall use its reasonable best efforts to resolve, and to cooperate and assist the other parties in resolving, any such objections, investigation or litigation, action or proceeding, and shall make such proposals and take such actions so as to permit the Merger and the other transactions contemplated by this Agreement to be consummated as promptly as practicable, and in any event prior to the Outside Date, in accordance with applicable Law (including the Antitrust Laws), including making proposals, executing and carrying out agreements and submitting to orders providing for divesting (or agreeing to divest) assets of the Company and its Subsidiaries that would not, individually or in the aggregate, reasonably be expected to be material to the Company and its Subsidiaries, taken as a whole.

(d) Each party to this Agreement shall (i) subject to Section 6.03(c) above, respond as promptly as reasonably practicable to any inquiries or requests for additional information and documentary material received from any Governmental Entity in connection with any antitrust or competition matters related to this Agreement and the transactions contemplated by this Agreement, (ii) not extend any waiting period or agree to refile under the HSR Act (except with the prior written consent of the other party hereto) and (iii) not enter into any agreement with any Governmental Entity agreeing not to consummate the transactions contemplated by this Agreement.

(e) Notwithstanding anything in this Agreement to the contrary, in the event that any decree, judgment, injunction or other order, whether temporary, preliminary or permanent (each, a “Proceeding”) is instituted, or threatened to be instituted challenging any of the transactions contemplated hereby as violative of any Antitrust Law and such Proceeding seeks to prevent, materially impede or materially delay the consummation of the Merger or any other transaction completed by this Agreement, each of the Company, Parent and Merger Sub shall cooperate with each other and use its respective reasonable best efforts to avoid, vacate, modify, or suspend each such Proceeding, including through litigation, unless, by agreement, the Parties determine that

litigation is not in their respective best interests; provided, however, except as expressly provided for in Section 6.03(c), that Parent and Merger Sub shall be under no obligation to make proposals, execute or carry out agreements or submit to orders providing for (i) the sale, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Parent or any of its Affiliates or the Company or any of its Subsidiaries, (ii) the imposition of any limitation or regulation on the ability of Parent or any of its Affiliates to freely conduct their business or own such assets, or (iii) the holding separate of the shares of the Company or any limitation or regulation on the ability of Parent or any of its Affiliates to exercise full rights of ownership of the shares of Company. Nothing in this Section 6.03 shall limit a party’s right to terminate this Agreement pursuant to Section 8.01(b)(i) if such party has, until such date, complied in all material respects with its obligations under this Section 6.03.

SECTION 6.04 Benefit Plans.

(a) For the period commencing at the Effective Time and ending on the earlier of (x) the date that is twelve (12) months following the Effective Time and (y) the date on which the employment of an employee of the Company and its Subsidiaries who continues his or her employment with the Surviving Corporation or its Subsidiaries following the Effective Time (each, a “Company Employee” and, collectively, the “Company Employees”) terminates, the Surviving Corporation shall provide each Company Employee with employee benefits that are no less favorable in the aggregate than the employee benefits provided to similarly situated Parent employees; and, for the period commencing at the Effective Time and ending on the earlier of (x) the date that is six (6) months following the Effective Time and (y) the date on which the employment of a Company Employee terminates, the Surviving Corporation shall provide each Company Employee with (A) at least the same wage rate or annual rate of base salary, as applicable, as was provided to such Company Employee immediately prior to the Effective Time, and (B) an opportunity to earn an amount of ordinary course annual performance bonus and commission opportunities (not including equity or equity related-related incentive compensation) that are substantially comparable in the aggregate to the amount of ordinary course annual bonus and commission opportunities that were available to such Company Employee immediately prior to the Effective Time; provided, however, that neither Parent nor the Surviving Corporation (or any of their respective Affiliates) shall be under any obligation to either (1) retain any employee or group of employees of the Company or any of its Subsidiaries or (2) retain any Company Benefit Plan, other than as required by applicable Law; and provided further, however, to the extent that, prior to the Effective Time, the employees of the Company or its Subsidiaries named on Section 6.04(a) of the Company Disclosure Schedule as of the Agreement Date enter into offer letters regarding their employment (including compensation and benefits) after the Effective Time, each such offer letter shall supersede this Section 6.04(a) with respect to the employee party to such offer letter. Neither Parent nor Merger Sub have provided notice to Company and/or its Subsidiaries of any actual or anticipated actions by Parent and/or Merger Sub that would give rise to an obligation on the part of Company and/or its Subsidiaries to provide notice under the Worker Adjustment and Retraining Notification Act, as amended, or any similar state or local law.

(b) With respect to any “employee benefit plan”, as defined in Section 3(3) of ERISA, maintained by Parent or any of its Subsidiaries excluding both any retiree healthcare plans or programs maintained by Parent or any of its Subsidiaries and any equity compensation arrangement maintained by Parent or any of its Subsidiaries but including any paid time off, vacation and severance pay arrangements (collectively, “Parent Benefit Plans”) in which any of the Company Employees will participate effective after the Effective Time, Parent shall, or shall cause the Surviving Corporation to, recognize all service of the Company Employees with the Company or any of its Subsidiaries, as the case may be (including service with any other predecessor employer of the Company or any such Subsidiary, to the extent service with such other predecessor employer is, or would have been, recognized by the Company or such Subsidiary), for purposes of determining vesting and eligibility (but not for (i) purposes of early retirement subsidies under any Parent Benefit Plan that is a defined benefit pension plan or (ii) benefit accrual purposes in any Parent Benefit Plan in which such Company Employees may be eligible to participate after the Effective Time); provided, however, that such service need not be recognized to the extent that such recognition would result in any duplication of benefits or to the extent that such service was not recognized under the corresponding Company Benefit Plan.

(c) Parent shall use its reasonable efforts to (i) recognize, or cause to be recognized, the dollar amount of all co-payments, deductibles and similar expenses incurred by each Company Employee (and his or her eligible dependents) during the calendar year in which the Effective Time occurs for purposes of satisfying such year’s deductible and co-payment limitations under the relevant welfare benefit plans in which they will be eligible to participate from and after the Effective Time and (ii) waive, or cause to be waived, any pre-existing condition limitations, exclusions, actively at work requirements and waiting periods under any Parent Benefit Plan that is a welfare benefit plan and in which Company Employees (and their eligible dependents) will be eligible to participate from and after the Effective Time, except to the extent that such pre-existing condition limitations, exclusions, actively-at-work requirements and waiting periods would not have been satisfied or waived under the comparable Company Benefit Plan(s) immediately prior to the Effective Time and provided that nothing in this Section 6.04(c) shall obligate Parent to provide any benefit under any Parent Benefit Plan that is a welfare benefit plan that it did not provide under such plan as of the Effective Time.

(d) The Company shall terminate all cash or deferred arrangements within the meaning of Section 401(k) of the Code (the “401(k) Plans”) sponsored, maintained or contributed to by the Company, effective not later than (x) if the Merger is effected by way of a Short Form Merger, the day immediately preceding the Share Acceptance Time or (y) if Shareholder Approval is required under the Business Corporation Law in order to consummate the Merger other than pursuant to Section 1924(b)(1)(ii) of the Business Corporation Law, the day immediately preceding the Closing Date (in either case, the “401(k) Plan Termination Date”). The Company shall provide Parent with evidence that such 401(k) Plan(s) have been terminated pursuant to a resolution of the Company Board (the form and substance of which shall be subject to review and approval by Parent) not later than the day immediately preceding 401(k) Plan Termination Date.

(e) The Company, Parent and Merger Sub acknowledge and agree that all provisions contained in this Section 6.04 and in Sections 4.01(l) and (n) with respect to Company Employees are included for the sole benefit of Parent, Merger Sub and the Company, and that nothing in this Agreement, whether express or implied, shall create any third party beneficiary or other rights (i) in any other Person, including any Company Employees, former Company Employees, any participant in any Company Benefit Plan, or any dependent or beneficiary thereof, or (ii) to continued employment with Parent, the Surviving Corporation, or any of their respective Affiliates. No provision of this Section 6.04 or Sections 4.01(l) or (n) shall constitute an amendment to any Company Benefit Plan or any employee benefit or compensation plan, policy agreement or arrangement of Merger Sub or any of its Affiliates.

SECTION 6.05 Section 16 Matters. Prior to the Effective Time, the Company Board, or an appropriate committee of non-employee directors thereof, shall adopt a resolution consistent with the interpretive guidance of the SEC so that the disposition by any officer or director of the Company who is a covered person of the Company for purposes of Section 16 of the Exchange Act and the rules and regulations promulgated thereunder (“Section 16”) of Shares or Company Stock Options pursuant to this Agreement, and the Offer and the Merger shall be an exempt transaction for purposes of Section 16.

SECTION 6.06 Rule 14d-10(d) Matters. Prior to the Share Acceptance Time, the Company (acting through the Compensation Committee of the Company Board which shall, at the time of such approval, consist entirely of independent directors as such term is defined in Rule 5605(a)(2) of the NASDAQ Marketplace Rules) will take all such steps as may be required to cause each agreement, arrangement or understanding entered into by the Company or its Subsidiaries on or after the Agreement Date with any of its officers, directors or employees pursuant to which consideration is paid to such officer, director or employee to be approved as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(1) under the Exchange Act and to satisfy the requirements of the non-exclusive safe harbor set forth in Rule 14d-10(d) under the Exchange Act.

SECTION 6.07 Indemnification, Exculpation and Insurance. (a) Parent agrees that all rights to indemnification of and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto now existing in favor of any Person who is or prior to the Effective Time becomes, or has been at any time prior to the Agreement Date, a director or officer of the Company (each, an “Indemnified Party”) to the extent that such Persons are entitled to such rights pursuant to and as provided in the Company Articles of Incorporation, the Company Bylaws or any indemnification agreement between such Indemnified Party and the Company (a true and complete copy of which has been made available to Parent), in each case, as in effect on the Agreement Date, shall remain in full force and effect for a period of six (6) years after the Effective Time (or in the case of any indemnification agreement providing for a longer period, until the expiration of the rights in accordance with the terms of such indemnification agreement). Such rights shall survive the Merger and shall, for a period of six (6) years after the Effective Time (or in the case of any indemnification agreement providing for a longer period, until the expiration of the rights in accordance with the terms of such indemnification agreement), not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such

Indemnified Party without the prior consent of the affected Indemnified Party. If written notice of a claim for indemnification pursuant to this Section 6.07 has been given prior to the expiration of the six (6) year (or longer) period referenced above, then no amendment, repeal or modification of this Section 6.07 shall adversely affect the Indemnified Party’s rights in respect of such claim.

(b) Parent shall either (i) cause to be maintained in effect, for a period of six (6) years after the Effective Time, the directors’ and officers’ liability insurance policy that is in effect at the Agreement Date (the “Current D&O Policy”) covering acts or omissions at or prior to the Effective Time with respect to those persons who are covered by the Current D&O Policy as of the Effective Time, or (ii) obtain, in consultation with the Company, a prepaid (or “tail”) directors’ and officers’ liability insurance policy covering acts or omissions occurring at or prior to the Effective Time for a period of six (6) years after the Effective Time, with respect to those persons who are covered by the Current D&O Policy as of the Effective Time on terms with respect to such coverage and amounts no less favorable to such indemnified persons than those of the Current D&O Policy; provided that in no event shall the aggregate costs of such insurance policies exceed in any one (1) year during the six (6) years after the Effective Time one-hundred fifty percent (150%) of the aggregate premiums paid by the Company for such purpose with respect to 2010 (which aggregate premiums with respect to 2010 are hereby represented and warranted by the Company to be $230,000), it being understood that Parent or the Surviving Corporation shall nevertheless be obligated to purchase such coverage, with respect to each year during such six (6) year period, as may be obtained for such one-hundred fifty percent (150%) annual amount; provided further that Parent or the Surviving Corporation may substitute therefor policies of any reputable insurance company, so long as such policies have terms with respect to coverage and amounts no less favorable to such indemnified persons than those of the Current D&O Policy.

(c) In the event that Parent or the Surviving Corporation 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 of its properties and other assets to any Person, or if Parent dissolves the Surviving Corporation, then, and in each such case, Parent shall cause proper provision to be made so that the applicable successors and assigns or transferees assume the obligations set forth in this Section 6.07.

(d) The provisions of this Section 6.07 are intended to be for the benefit of, and will be enforceable by, each Indemnified Party, his or her heirs and his or her representatives, and are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise. On and after the Share Acceptance Time, the provisions of this Section 6.07 may not be amended in a manner adverse to any Indemnified Party without his or her prior consent.

SECTION 6.08 Fees and Expenses.

(a) Except as provided elsewhere in this Section 6.08, all fees and expenses incurred in connection with this Agreement, the Merger and the other transactions contemplated hereby shall be paid by the party incurring such fees or expenses, whether or not such transactions are consummated.

(b) Notwithstanding anything to the contrary contained in this Agreement:

(i) In the event this Agreement is terminated by Parent pursuant to Section 8.01(e), then the Company shall pay to Parent the Company Termination Fee within one (1) Business Day following the date of such termination of this Agreement;

(ii) If this Agreement is terminated by the Company pursuant to Section 8.01(f), then the Company shall pay to Parent the Company Termination Fee immediately prior to, and as a condition to the effectiveness of, such termination of this Agreement; and

(iii) In the event that, prior to the date of termination of this Agreement (but in no event later than the Share Acceptance Time), a Takeover Proposal shall have been publicly made to the Company or shall have been made directly to the shareholders of the Company generally or shall have otherwise become publicly known, or any Person shall have publicly announced an intention to make a Takeover Proposal (whether or not conditional) and (A) thereafter this Agreement is terminated (1) by either Parent or the Company pursuant to Section 8.01(b)(i), (2) by Parent or the Company pursuant to Section 8.01(b)(ii) or (3) by Parent pursuant to Section 8.01(c) based on a willful breach of the Company’s covenants or agreements set forth in this Agreement and (B) within twelve (12) months after such termination, the Company enters into a definitive agreement to consummate or consummates an Acquisition Transaction, then the Company shall pay Parent an aggregate fee equal to the Company Termination Fee on the earlier of the date of entry into a definitive agreement or the date of consummation referred to above. For purposes of this Section 6.08(b)(iii), the term “Acquisition Transaction” shall have the meaning assigned to such term in Section 5.02(a)(i), except that all references to ten percent (10%) therein shall be deemed to be references to fifty percent (50%).

(iv) All payments under this Section 6.08 shall be made by wire transfer of immediately available funds to an account designated in writing by Parent.

(c) The Company acknowledges and agrees that the agreements contained in this Section 6.08 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not have entered into this Agreement. Accordingly, if the Company fails promptly to pay the amount due pursuant to this Section 6.08, the Company shall pay to Parent its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with collection under and enforcement of this Section 6.08 (only if and

to the extent such collection and enforcement actions are determined in Parent’s favor), together with interest on the amount of the Company Termination Fee from the date such payment was required to be made until the date of payment at the prime rate of Citibank N.A. in effect on the date such payment was required to be made.

SECTION 6.09 Public Announcements. Each of Parent, Merger Sub and the Company 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, conditioned or delayed), except as such release or announcement may be required by applicable Law, court process or the rules and regulations of any national securities exchange or national securities quotation system and except for any matters referred to in Section 5.02, 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 required, shall be at the final discretion of the disclosing party. The Company, Merger Sub and Parent agree that the Company, on the one hand, and Parent and Merger Sub, on the other hand, shall each cause a separate press release announcing the execution and delivery of this Agreement, which shall not be issued prior to the approval of each of, the Company and Parent.

SECTION 6.10 Shareholder Litigation.

(i) to the Knowledge of the Company, the occurrence of any state of facts, change, development, event or condition that would cause or result, or would reasonably be expected to cause or result, in any of the conditions to the Offer or the Merger set forth in Annex II or Article VII not being satisfied or satisfaction of any of those conditions being materially delayed;

SECTION 9.08 Specific Enforcement; Consent to Jurisdiction; Waiver of Jury Trial.

(a) The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that until such time as this Agreement is validly terminated pursuant to the provisions of Section 8.01, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the United States District Court for the District of Delaware or any other competent court of the State of Delaware (collectively, the “Delaware Courts”), this being in addition to any other remedy to which they are entitled at law or in equity. The pursuit of specific enforcement by either party will not be deemed an election of remedies or waiver of the right to pursue any other right or remedy to which such party may be entitled.

(b) Each of the parties hereto hereby (i) irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Delaware Courts in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection

herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any Delaware Court, (iii) agrees that it will not bring any such action or proceeding in any court other than the Delaware Courts, (iv) agrees that any Claim in respect of any such action or proceeding may be heard and determined in any Delaware Court, (v) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any Delaware Court and (vi) waives, to the fullest extent it may legally and effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding in any Delaware Court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.02. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.08(c).

SECTION 9.09 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

SECTION 9.10 Interpretation. When a reference is made in this Agreement to an Article, a Section or Exhibit, such reference shall be to an Article or a Section of, or an Exhibit to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or

interpretation of this Agreement. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”. The words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The word “or” when used in this Agreement is not exclusive. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. References to a Person are also to its permitted successors and assigns.

The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intention or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

SECTION 9.11 Counterparts. This Agreement may be executed in one or more counterparts (including by facsimile or portable document format (.PDF)), all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

WHEREAS, Parent, Merger Sub and the Company propose to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), which provides for Merger Sub to commence a tender offer (the “Offer”) for all of the issued and outstanding shares of the Common Stock and the merger of Merger Sub with and into the Company, with the Company surviving as a direct or indirect wholly-owned subsidiary of Parent (the “Merger”); and

WHEREAS, as a condition to the willingness of Parent and Merger Sub to enter into the Merger Agreement and as an inducement and in consideration therefor, Shareholder has agreed to enter into this Agreement.

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

(b) Shareholder has the legal capacity to execute and deliver this Agreement and to consummate the transactions contemplated hereby.

(d) Neither the execution and delivery of this Agreement nor the consummation by Shareholder of the transactions contemplated hereby will result in a violation of, or a default under, or conflict with, any contract, trust, commitment, agreement, understanding, arrangement or restriction of any kind to which Shareholder is a party or by which Shareholder or Shareholder’s assets are bound. Except for compliance with the applicable provisions of Sections 13 and 16 of the Exchange Act, the consummation by Shareholder of the transactions contemplated hereby will not violate, or require any consent, approval, or notice under, any provision of any judgment, order, decree, statute, law, rule or regulation applicable to Shareholder.

(e) The Shares owned, the certificates representing the Shares held of record, and, to the Shareholder’s knowledge, the certificates representing the Shares owned, but not held of record, by Shareholder are now, and at all times during the term hereof will be, held by Shareholder, or by a nominee or custodian for the benefit of Shareholder, free and clear of all liens, claims, security interests, proxies, voting trusts or agreements, options, rights, understandings or arrangements or any other encumbrances whatsoever on title, transfer, or exercise of any rights of a shareholder in respect of such Shares, except for any of the foregoing arising under this Agreement.

SECTION 2. Representations and Warranties of Parent and Merger Sub.

Each of Parent and Merger Sub hereby, jointly and severally, represents and warrants to Shareholder as follows:

(b) This Agreement has been duly authorized, executed and delivered by each of Parent and Merger Sub, and constitutes the legal, valid and binding obligation of each of Parent and Merger Sub, enforceable against each of them in accordance with its terms, subject, as to enforceability, to bankruptcy, insolvency and other Laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

SECTION 3. Tender of the Shares. Each Shareholder hereby agrees that unless this Agreement is terminated pursuant to Section 7 hereof, (a) Shareholder shall validly tender or cause to be validly tendered its Shares to Merger Sub pursuant to the Offer as promptly as practicable, and in any event no later than the tenth business day following the commencement of the Offer pursuant to Section 1.01 of the Merger Agreement, and (b) Shareholder shall not withdraw or cause to be withdrawn any of Shareholder’s Shares so tendered unless the Offer is terminated or the Offer has expired without Merger Sub purchasing all shares of Common Stock validly tendered in the Offer.

SECTION 4. Transfer of the Shares.

Prior to the termination of this Agreement, except as otherwise provided herein, Shareholder shall not: (a) transfer, assign, sell, gift-over, pledge or otherwise dispose of, or consent to any of the foregoing (“Transfer”), any or all of the Shares or any right or interest therein; (b) enter into any contract, option or other agreement, arrangement or understanding with respect to any Transfer; (c) grant any proxy, power-of-attorney or other authorization or consent with respect to any of the Shares; (d) deposit any of the Shares into a voting trust, or enter into a voting agreement or arrangement with respect to any of the Shares; (e) exercise, or give notice of an intent to exercise, any Options unless the Shares underlying such Options become subject to this Agreement upon such Option exercise; or (f) take any other action, other than in Shareholder’s capacity as an officer or director of the Company, that would in any way restrict, limit or interfere with the performance of Shareholder’s obligations hereunder or the transactions contemplated hereby.

SECTION 5. Grant of Irrevocable Proxy; Appointment of Proxy.

(a) Shareholder hereby irrevocably grants to, and appoints, Parent and any designee thereof, Shareholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of Shareholder, to vote the Shares, or to grant a consent or approval in respect of the Shares, in connection with any meeting of the shareholders of the Company or any action by written consent in lieu of a meeting of shareholders of the Company (i) in favor of the Merger or any other transaction pursuant to which Parent or Merger Sub proposes to acquire the Company, whether by tender offer, merger, or otherwise, in which shareholders of the Company would receive consideration per share of Common Stock equal to or greater than the consideration to be received by such shareholders in the Offer and the Merger, and/or (ii) against any action or agreement which would impede, interfere with or prevent the Merger, including, but not limited to, any other extraordinary corporate transaction, including a merger, acquisition, sale, consolidation, reorganization or liquidation involving the Company and a third party, or any other proposal of a third party to acquire the Company.

(b) Shareholder represents that any proxies heretofore given in respect of the Shares, if any, are revocable, and hereby revokes any such proxies.

(c) Shareholder hereby affirms that the irrevocable proxy set forth in this Section 5 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of Shareholder under this Agreement. Shareholder hereby further affirms that the irrevocable proxy is coupled with an interest and, except as set forth in Section 7 hereof, is intended to be irrevocable in accordance with the provisions of Section 1759 of the Pennsylvania Business Corporation Law. If for any reason the proxy granted herein is not irrevocable, then Shareholder agrees to vote Shareholder’s Shares as instructed by Parent in writing.

or assist or participate in, or facilitate or take any action that could reasonably be expected to facilitate, any such inquiries, proposals, offers, discussions or negotiations; provided, however, that nothing herein shall prevent Shareholder from acting in his or her capacity as an officer or director of the Company, or taking any action in such capacity (including at the direction of the Company Board), but only in either such case as and to the extent permitted by Section 5.02(b) of the Merger Agreement. Shareholder shall immediately cease participating in any solicitation, discussion or negotiation with any Person with respect to any actual or potential Acquisition Transaction.

SECTION 7. Termination. This Agreement shall terminate, and neither Parent nor Shareholder shall have any rights or obligations hereunder and this Agreement shall become null and void and have no effect upon the earlier to occur of (i) the Effective Time and (ii) the date of termination of the Merger Agreement in accordance with its terms; provided, however, that termination of this Agreement shall not prevent any party hereunder from seeking any remedies (at law or in equity) against any other party hereto for such party’s breach of any of the terms of this Agreement. Notwithstanding the foregoing, Sections 8(a), 8(e), 8(f), 8(j), 8(k), 8(l), and 8(n) of this Agreement shall survive the termination of this Agreement.

SECTION 8. Miscellaneous.

(a) Notices.

(d) Amendment, Waivers, etc. This Agreement may not be amended, changed, supplemented, waived or otherwise modified, except upon the execution and delivery of a written agreement executed by each of the parties hereto. The failure of any party hereto to exercise any right, power or remedy provided under this Agreement or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other party hereto with its obligations hereunder, and any custom or practice of the parties at variance with the terms hereof shall not constitute a waiver by such party of its right to exercise any such or other right, power or remedy or to demand such compliance.

(e) Specific Performance. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that until such time as this Agreement is validly terminated pursuant to the provisions of Section 7, the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the United States District Court for the District of Delaware or any other competent court of the State of Delaware (collectively, the “Delaware Courts”), this being in addition to any other remedy to which they are entitled at law or in equity. The pursuit of specific enforcement by either party will not be deemed an election of remedies or waiver of the right to pursue any other right or remedy to which such party may be entitled.

(f) Capitalized Terms. For purposes of this Agreement, capitalized terms used and not defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

(g) Entire Agreement. This Agreement (together with the Merger Agreement, to the extent referred to herein) constitutes the entire agreement of the parties and supersedes all prior agreements and undertakings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof.

(h) Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties without the prior written consent of the other parties, and any assignment without such consent shall be null and void; provided, however, that Merger Sub may assign, in its sole and absolute discretion, any or all of its rights, interests and obligations under this Agreement to Parent or any direct or indirect wholly owned Subsidiary of Parent. No assignment (including an assignment to which the Company has consented) shall release Parent of its obligations hereunder. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

(i) Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to and does not confer upon any Person other than the parties any legal or equitable rights or remedies, whether as third party beneficiaries or otherwise.

(j) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS (WHETHER OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY STATE OTHER THAN THE STATE OF DELAWARE, EXCEPT TO THE EXTENT THAT MANDATORY PROVISIONS OF THE BUSINESS CORPORATION LAW ARE APPLICABLE HERETO.

(k) Consent to Jurisdiction. Each of the parties hereto hereby (i) irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Delaware Courts in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any Delaware Court, (iii) agrees that it will not bring any such action or proceeding in any court other than the Delaware Courts, (iv) agrees that any Claim in respect of any such action or proceeding may be heard and determined in any Delaware Court, (v) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any Delaware Court and (vi) waives, to the fullest extent it may legally and effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding in any Delaware Court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each party to this Agreement irrevocably consents to service of process in the manner provided

for notices in Section 8(a). Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

(l) Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8(l).

(m) Counterparts. This Agreement may be executed in one or more counterparts (including by facsimile or portable document format (.PDF)), all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

(n) Action in Shareholder Capacity Only. Parent and Merger Sub acknowledge that Shareholder has entered into this Agreement solely in its capacity as the record and/or beneficial owner of the Shares and not in any capacity as a director or officer of the Company. Nothing herein shall limit or affect any actions taken by Shareholder or its Affiliates or designee, or require Shareholder or its Affiliates or designee to take any action, in each case, in his or her capacity as a director or officer of the Company, and any actions taken, or failure to take any actions, by such a director or officer in such capacity shall not be deemed to constitute a breach of this Agreement (it being understood that the matters that are the subject of Section 6 hereof are subject to Section 5.02 of the Merger Agreement as it relates to such director or officer in his or her capacity as such).

IN WITNESS WHEREOF, Parent, Merger Sub and Shareholder have caused this Agreement to be duly executed and delivered as of the date first written above.

Bryant Zanko

Vice President, Business Development

Stryker Corporation

Road Kalamazoo, MI 49002

Dear Bryant:

You have requested information regarding Orthovita, Inc. (the “Company”, “us” or “we”) in connection with your consideration of a possible negotiated transaction with the Company (a “Possible Transaction”). For purposes of this agreement, the term “Company” includes the Company and its subsidiaries taken as a whole or any business or businesses thereof. In consideration of our furnishing you with the Evaluation Materials (as defined below) you agree as follows:

Confidentiality of Evaluation Materials

You will treat confidentially any information (whether written or oral) that either we or our financial advisor, J.P. Morgan Securities LLC (the “Financial Advisor”), or our other representatives furnish to you in connection with a Possible Transaction involving the Company, whether furnished before or after the date of this agreement and regardless of the manner in which it is furnished, together with analyses, compilations, studies or other documents prepared by you, or by your representatives (as defined hereinafter) which contain or otherwise reflect such information or your review of, or interest in, the Company (collectively, the “Evaluation Materials”).

The term “Evaluation Materials” includes information furnished to you orally or in writing (whatever the form or storage medium) or gathered by inspection, and regardless of whether such information is specifically identified as “confidential” including, but not limited to, all conversations, meetings, negotiations, discussions, internal memoranda, documents and notes involving the Company and the Possible Transaction. The term “Evaluation Materials” does not include information which (i) is or becomes generally available to you or the public other than as a result of a disclosure by you or your representatives, (ii) was or becomes available to you on a non-confidential basis from a source other than the Company or its representatives, provided that to your knowledge, after due inquiry, such source is not prohibited from disclosing such information to you by a contractual, legal or fiduciary obligation to the Company or its representatives or (iii) is independently developed by you without violating your obligations hereunder.

Use of Evaluation Materials

You will not use any of the Evaluation Materials for any purpose other than the exclusive purpose of evaluating a Possible Transaction. Except as required by law, you and your representatives will keep the Evaluation Materials confidential; provided, however, that (i) such information may be disclosed to those of your directors, officers, employees, affiliates, agents and representatives (including attorneys, accountants and financial advisors), lenders and other sources of debt financing (collectively, “your representatives”) who need to know such information for the purpose of evaluating a Possible Transaction between you and the Company (it being understood that your representatives shall be informed by you of the confidential nature of such information and shall be directed by you to treat such information as confidential in accordance with this agreement and shall be under obligations of confidentiality with respect to such information) and (ii) any other disclosure of such information may only be made if the Company consents in writing prior to any such disclosure. Without limiting the generality of the foregoing, in the event that a Possible Transaction is not consummated, neither you nor your representatives shall use any of the Evaluation Materials for any purpose. You will be responsible for any breach of this agreement by you or your representatives.

You hereby acknowledge that the Company is a publicly traded company. You further hereby acknowledge that you are aware, and that you will advise your representatives who are informed as to the matters which are the subject of this agreement, that the United States securities laws prohibit any person who has received from an issuer material, non-public information from purchasing or selling securities of such issuer or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities.

If you become aware of any unauthorized disclosure or use of any Evaluation Materials, you hereby covenant to promptly notify the Company. Moreover, upon the request of the Company, you shall cooperate in assisting the Company in terminating or preventing any third parties from disseminating or using the Evaluation Materials.

In the event that you or any of your representatives receive a request or are required (by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process) to disclose all or any part of the Evaluation Materials, you or your representatives, as the case may be, hereby agree to (i) immediately notify the Company of the existence, terms and circumstances surrounding such request, (ii) unless to the extent legally impracticable, consult with the Company on the advisability of taking legally available steps to resist or narrow such request and (iii) unless to the extent legally impracticable, afford the Company with the opportunity to seek a protective order or other appropriate remedy. If your or your representatives’ counsel advises that you or your representatives are legally compelled to disclose the Evaluation Materials to any person, (i) you or your representatives, as the case may be, may,

without liability hereunder, disclose to such person only that portion of the Evaluation Materials which your counsel advised you is legally required to be disclosed. You agree to cooperate with the Company, at the Company’s expense, to obtain assurance that confidential treatment will be accorded such Evaluation Materials.

Non-Disclosure

The disclosure of your possible interest in a Possible Transaction could have a material adverse effect on the Company and its business if for any reason an agreement of purchase and sale is not consummated or a disclosure is made prior to the closing of a Possible Transaction. Accordingly, unless required by applicable law or regulatory authority, you agree that prior to the closing of a Possible Transaction, without the prior written consent of the Company, you will not, and you will direct your representatives not to, disclose to any person the fact that the Evaluation Materials have been made available to you, discussions or negotiations have taken or are taking place concerning a Possible Transaction between the Company and you or any of the terms, conditions or other facts with respect to any such Possible Transaction, including the status thereof, The term “person” as used in this agreement shall be broadly interpreted to include, without limitation, the media, any corporation or limited liability company, the Company, governmental agency or body, stock exchange, partnership, association or individual.

Ownership and Return of Evaluation Materials

All Evaluation Materials disclosed by or on behalf of the Company shall be and shall remain in the property of the Company. Upon the Company’s request, you shall promptly deliver to the Company or destroy all written Evaluation Materials without retaining, in whole or in part, any copies, extracts or other reproductions (whatever the form or storage medium) of such materials, and shall certify the delivery or destruction, as applicable, of all such materials in writing to the Company; provided that economic analyses, privileged communication with your counsel and other proprietary documentation shall not be required to be delivered to the Company but shall be destroyed as set forth in this sentence and provided further that you may retain one copy of the Evaluation Materials in a secure location within your Legal Department. Notwithstanding the return or destruction of the Evaluation Materials, you and your representatives will continue to be bound by your obligations of confidentiality and other obligations hereunder.

No Unauthorized Contact or Solicitation

During the course of your evaluation, all inquiries and other communications are to be made directly to the Financial Advisor or employees or representatives of the Company specified by the Financial Advisor. Accordingly, except as set forth in the preceding sentence, you agree not to directly or indirectly contact or communicate with any executive or other employee of the Company (in their capacities as officers or employees of the Company) concerning a Possible Transaction, or to seek any information in connection therewith from such person, without the express written consent of the Financial Advisor. You also agree not to discuss with or offer to any third party any equity participation in a Possible Transaction or any other form of joint acquisition by you and such third party without the prior written consent of the Company.

Without the Company’s prior written consent, you will not for a period of eighteen months after the date of this agreement directly or indirectly solicit for employment any person who is now employed by the Company in an executive-level position, or any person who is now employed by the Company in a management-level position at the Company’s headquarters in Malvern, Pennsylvania, provided that you are not prohibited from employing any such person who contacts you on his or her own initiative and without any direct or indirect solicitation by you and the term “solicit for employment” shall not be deemed to include general solicitations of employment not specifically directed toward employees of the Company.

Standstill

You agree that until eighteen months after the date of this agreement, you will not without the prior approval of the Board of Directors of the Company (i) acquire or make any proposal to acquire any securities or property of the Company or to acquire any ability to exercise voting or dispositive power with respect to any securities of the Company, (ii) propose to enter into any merger or business combination involving the Company or purchase a material portion of the assets of the Company, (iii) make or participate in any solicitation of proxies to vote, or seek to advise or influence any person with respect to the voting of any securities of the Company, (iv) form, join or participate in a “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended), with respect to any voting securities of the Company, (v) otherwise act or seek to control or influence the management, Board of Directors or policies of the Company, (vi) disclose any intention, plan or arrangement inconsistent with the foregoing or (vii) take any action which might require the Company to make a public announcement regarding the possibility of a business combination or merger. You also agree during such period not to request the Company (or its directors, officers, employees, agents or representatives) to amend or waive any provision of this paragraph unless specifically invited to do so by the Board of Directors of the Company. Notwithstanding the restrictions in this paragraph, after the Company has announced that it has entered into a definitive written agreement with a third party with respect to a business combination transaction that, if consummated, would result in a transfer of corporate control of the Company, you may make an acquisition proposal to the Company’s Board of Directors.

No Representation or Warranty

You acknowledge and agree that none of the Company, the Financial Advisor, or any of their respective representatives or agents is making any representation or warranty, expressed or implied, as to the accuracy or completeness of the Evaluation Materials, and none of the Company, the Financial Advisor, or any of their respective representatives or agents, nor any of their respective officers, directors, employees, representatives, stockholders, owners, affiliates, advisors or agents, will have any liability to you or any other person resulting from the use of Evaluation Materials by you or any of your representatives. Furthermore, nothing contained herein shall constitute an obligation on the part of the Company, the Financial Advisor, or any of their respective representatives or agents to provide Evaluation Materials or to update any Evaluation Materials provided hereunder. Only those representations or warranties that are made to you in a definitive agreement for the Possible Transaction (“Definitive Agreement”) when, as,

and if it is executed, and subject to such limitations and restrictions as may be specified in such Definitive Agreement, will have any legal effect. For purposes of this agreement, the term “Definitive Agreement” does not include an executed non-binding letter of intent or any other non-binding written agreement, nor does it include any oral acceptance of an offer or bid by you.

You also acknowledge and agree that no contract or agreement providing for the sale of the Company or any interest in the Company shall be deemed to exist between you and the Company unless and until a Definitive Agreement has been executed and delivered by you and each of the other parties thereto, and you hereby waive, in advance, any claims (including, without limitation, breach of contract) in connection with the sale of the Company or any interest in the Company unless and until a Definitive Agreement has been executed and delivered by you and each of the other parties thereto. You also agree that unless and until a Definitive Agreement between the Company and you with respect to the acquisition of the Company or any interest in the Company has been executed and delivered by you and each of the other parties thereto, there shall not be any legal obligation of any kind whatsoever with respect to any such transaction by virtue of this agreement or any other written or oral expression with respect to such transaction except, in the case of this agreement, for the matters specifically agreed to herein.

You further understand and agree that (i) the Company and the Financial Advisor shall be free to conduct any process for the sale of the Company or any interest in the Company as they in their sole discretion shall determine (including, without limitation, negotiating with any prospective counterparty and entering into a Definitive Agreement without prior notice to you or to any other person), (ii) any procedures relating to such sale may be changed at any time without notice to you or any other person and (iii) you shall not have any claims whatsoever against the Company, the Financial Advisor or any of their respective directors, officers, employees, stockholders, owners, affiliates, agents or representatives arising out of or relating to a Possible Transaction involving the Company. You further understand and agree that the Company reserves the right, in its sole discretion, to reject any and all proposals made by you or any of your representatives with regard to any Possible Transaction, and to terminate discussions and negotiations with you at any time. Neither this paragraph nor any other provision in this agreement can be waived or amended except by written consent of the Company, which consent shall specifically refer to this paragraph (or such provision) and explicitly make such waiver or amendment.

Legal Remedy

You understand and agree that money damages would not be a sufficient remedy for any breach of this agreement by you or your representatives and that the Company will be entitled to specific performance and injunctive relief as remedies for any such breach. Such remedies shall not be deemed to be the exclusive remedies for a breach of this agreement by you or your representatives but shall be in addition to all other remedies available at law or equity. In the event of litigation relating to this agreement, if a court of competent jurisdiction determines that you or your representatives have breached this agreement, then you shall reimburse the Company for its reasonable legal fees and expenses incurred in connection with such litigation, including

any appeals therefrom. Similarly, if a court of competent jurisdiction determines that you and/or your representatives did not breach this agreement, then the Company shall reimburse you and/or your representatives for your reasonable legal fees and expenses incurred in connection with such litigation, including any appeals therefrom.

Other

This agreement constitutes the entire agreement between the parties hereto regarding the subject matter hereof. This agreement may be changed only by a written agreement signed by the parties hereto or their authorized representatives.

To the extent that any Evaluation Material may include materials subject to the attorney-client privilege, work product doctrine or any other applicable privilege concerning pending or threatened legal proceedings or governmental investigations, you and the Company understand and agree that you and the Company have a commonality of interest with respect to such matters and it is the Company’s and your desire, intention and mutual understanding that the sharing of such material is not intended to, and shall not, waive or diminish in any way the confidentiality of such material or its continued protection under the attorney-client privilege, work product doctrine or other applicable privilege. All Evaluation Material provided that is entitled to protection under the attorney-client privilege, work product doctrine or other applicable privilege shall remain entitled to such protection under these privileges, this agreement, and under the joint defense doctrine.

If any term or provision of this agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms and provisions of this agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

The parties understand and agree that no failure or delay by the other party in exercising any right, power or privilege under this agreement shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or future exercise of any right, power or privilege hereunder.

This agreement shall be governed by and construed in accordance with the laws of the State of New York. You also hereby irrevocably and unconditionally consent to submit to the exclusive jurisdiction of the courts of the State of New York and the United States of America, in each case located in the County of New York, for any actions, suits or proceedings arising out of or relating to this agreement and the transactions contemplated hereby (and you agree not to commence any action, suit or proceeding relating thereto except in such courts, and further agree that service of any process, summons, notice or document by U.S. registered mail to your address set forth above shall be effective service of process for any action, suit or proceeding brought against you in any such court). You hereby irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding arising out of this agreement or the transactions contemplated hereby, in the courts of the State of New York or the United States

of America, in each case located in the County of New York, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

This agreement shall terminate two years after the date hereof.

If you are in agreement with the foregoing, please sign and return one copy of this agreement, it being understood that all counterpart copies will constitute but one agreement with respect to the subject matter of this letter.

Dear Bryant:

Reference is made to that certain letter agreement dated as of January 18, 2011 (the “Agreement”) by and between Orthovita, Inc. (the “Company”) and Stryker Corporation (“Stryker”) in connection with Stryker’s consideration of a possible negotiated transaction with the Company. Capitalized terms used herein and not otherwise defined herein shall have the meanings given to them in the Agreement.

In order for Stryker to receive access to a substantial amount of diligence information regarding the Company as part of the next phase of the process contemplated under the Agreement, the Company requires Stryker to amend the Agreement in order to extend the confidentiality period thereunder applicable to trade secrets.

Accordingly, the sentence on the last page of the Agreement that states, “This agreement shall terminate two years after the date hereof,” is amended and restated in its entirety to read as follows:

“This agreement shall terminate two years after the date hereof, provided that the obligations set forth under Use of Evaluation Materials insofar as they relate to the use and disclosure of a trade secret shall continue for so long as such trade secret continues to be a trade secret as defined under 18 U.S.C. §1839(3)(A), (B) (1996), and only if the Company identified the general subject matter of such trade secret to you in writing prior to disclosure to you and gave you the opportunity to decline receipt of such trade secret. Neither the foregoing nor the restrictions in this agreement applicable to trade secrets is intended to preclude you from using residual knowledge retained in intangible form in the unaided memories of your directors, employees, contractors and advisors as a result of exposure to the Company’s Evaluation Material. The Company acknowledges that you may have in conception or development technology that may be very similar or even identical to the Company’s trade secrets disclosed as part of the Evaluation Material.”

Except as specifically provided herein all other terms and conditions of the Agreement shall remain unchanged and in full force and effect.

If you are in agreement with the foregoing, please sign and return one copy of this amendment to the Agreement, it being understood that all counterpart copies will constitute but one agreement with respect to the subject matter of this letter.

CONFIDENTIALITY AGREEMENT

THIS CONFIDENTIALITY AGREEMENT (“Agreement”) is made as of April 27, 2011 by and among Stryker Corporation, a Michigan corporation (collectively with its subsidiaries and Affiliates, “Stryker”); King & Spalding LLP (“K&S”) and Lerner, David, Littenberg, Krumholz & Mentlik LLP (“LDLKM”), counsel to Stryker (collectively, lithe Stryker Advisors”); and Orthovita, Inc., a Pennsylvania corporation (collectively with its subsidiaries and Affiliates, “Orthovita”) (all heretofore named parties are collectively referred to herein as the “Parties”).

RECITALS

WHEREAS, Stryker and Orthovita are exploring a possible business relationship, arrangement or transaction with each other (the “Possible Transaction”);

WHEREAS, Stryker and Orthovita entered into a January 18, 2011 letter agreement relating to confidentiality, as amended February 25, 2011 (the “Existing Confidentiality Agreement”);

WHEREAS, Stryker has retained the Stryker Advisors to provide legal assistance in connection with the Possible Transaction (the “Evaluation”);

WHEREAS, the Parties wish to facilitate the provision by Orthovita of information and materials to the Stryker Advisors, but also desire to ensure that appropriate safeguards and restrictions are followed with respect to the transmittal of any such information and materials to the Stryker Advisors.

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, hereby agree as follows:

1. In order to permit Stryker to conduct the Evaluation, Orthovita or its employees, officers, or other representatives will provide to the Stryker Advisors, orally, in writing, or by other means, the Trade Secret Information (as defined below). The Stryker Advisors agree that they will use the Trade Secret Information only for the purposes of the Evaluation and will not share with Stryker or any other person any Trade Secret Information except in accordance with the terms of this Agreement or as authorized in advance in writing by Orthovita or its representative.

2. As used in this agreement, the term “Trade Secret Information” means information or materials that have, are related to or reflecting (A) collagen processing techniques pertaining to medical grade collagen, Vitagel, Vitastat and other hemostat products, (B) details of the composition of, exact formulations of raw materials, quality assurance test release criteria

and manufacturing processes for Vitoss, Vitoss BA, Vitoss Foam Products, Vitoss Flowable Products, Vitoss Elemental, Vitoss BA Bimodal, Vitoss BA2X, Vitagel, Vitastat and BA PEEK, (C) exact method of making combeite (heat-treated bioactive glass), (D) sileanation of bioactive glass (currently used in Cortoss), (E) details of the Cortoss formulation and manufacturing process.

Trade Secret Information shall not include, however, information that (i) is or has been made available to Stryker by Orthovita or its representatives (provided that this subsection (i) shall not apply to Trade Secret Information made available to Stryker by the Stryker Advisors), (ii) is or becomes available to the public other than as a result of disclosure in breach of this Agreement, or (iii) is or becomes available to Stryker or the Stryker Advisors from a source other than Orthovita or its representatives, provided that, to the best of Stryker’s or a Stryker Advisor’s knowledge, such source is in lawful possession of such information and is not bound by any agreement with Orthovita to keep such information confidential, or otherwise prohibited from transmitting such information to Stryker or any Stryker Advisor.

3. Nothing in this Agreement shall (i) prohibit the Stryker Advisors from conducting investigations based on the Trade Secret Information, provided that no source of information under such investigation is known by Stryker or any Stryker Advisor, to the best of its knowledge, to be bound by any agreement with Orthovita to keep such information confidential, and otherwise is not prohibited from transmitting such information to Stryker or any Stryker Advisor, (ii) prohibit the Stryker Advisors from advising Stryker regarding the Stryker Advisors’ opinions based on their investigations, and the general reasons for its opinions, about any matters for which the Stryker Advisors are engaged to advise Stryker, or (iii) require the Stryker Advisors to obtain prior review or approval from Orthovita before rendering such opinions to Stryker.

4. The Stryker Advisors shall not disclose Trade Secret Information to any third party, including a third party consultant engaged to assist in the Evaluation (a “Consultant”) unless, prior to any such disclosure, such Consultant agrees in writing to be bound by the terms of this Agreement, the Stryker Advisors notify Orthovita of the identity of such Consultant and Orthovita approves in writing the disclosure of Trade Secret Information to such Consultant.

5. To the extent that Stryker inadvertently receives information, whether oral or written, that it reasonably believes constitutes, contains, or discloses Trade Secret Information, Stryker shall: (i) promptly report such receipt to Orthovita; and (ii) promptly turn over all originals and copies (including all electronic copies in any media) of such Trade Secret Information, to the extent it is written, to Orthovita. If confirmed to be Trade Secret Information, Stryker agrees to maintain such Trade Secret Information in confidence so long as it remains a trade secret. If not confirmed to be Trade Secret Information, Orthovita shall return all materials turned over by Stryker to the extent that the Evaluation is ongoing.

6. Upon the request of Orthovita or its representative, and within two (2) weeks after such request (unless another time frame is agreed to in writing by the Parties), the Stryker Advisors shall return all originals and copies of any Trade Secret Information (including all electronic copies in any media) to Orthovita and shall destroy all notes, hard copies and electronic copies, that contain or disclose Trade Secret Information, and shall certify as to such destruction to Orthovita in writing.

7. Each of Stryker and the Stryker Advisors acknowledges that money damages are an inadequate remedy for breach of this Agreement because of the difficulty of ascertaining the amount of damage that may be suffered in the event that this Agreement is breached and other factors, including irreparable injury to Orthovita. Therefore, Orthovita shall be entitled to such equitable relief as may be appropriate, including an injunction and specific performance, in the event of any breach of the provisions of this Agreement by any other Party, in addition to all other remedies available to Orthovita at law or in equity.

(a) This Agreement and all disputes or controversies arising out of or relating to 2 or seeking to enforce this Agreement shall be governed by, and construed in accordance with, the internal laws of the State of Delaware, without regard to the laws of any other jurisdiction that might be applied because of the conflicts of laws principles.

ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 8(b) WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

9. Nothing herein shall preclude the Stryker Advisors from disclosing any Trade Secret Information, to the extent required by applicable law or valid subpoena provided that, with respect to each of the foregoing and: (i) the Stryker Advisors shall notify Orthovita of the existence, terms and circumstances surrounding such disclosure as far in advance as is reasonably practicable and consult with Orthovita on the advisability of taking steps available under applicable law to resist or narrow the scope of any such compelled disclosure, (ii) the Stryker Advisors shall reasonably cooperate with Orthovita in taking any such steps to resist or narrow the scope of any such disclosure as may be requested by Orthovita, (iii) the Stryker Advisors shall exercise their reasonable best efforts to provide such information on a confidential basis or obtain an order or other assurance that confidential treatment will be accorded to such

information, and (iv) the Stryker Advisors shall exercise their reasonable best efforts to permit Orthovita or its counsel, at Orthovita’s expense, to attend all depositions and other proceedings pertaining to such disclosure.

10. The Parties hereby agree that this Agreement shall not be construed in any manner to be an obligation to proceed with the Proposed Transaction.

11. Orthovita shall not use the disclosure of the Trade Secret Information to the Stryker Advisors to disqualify the Stryker Advisors from representing Stryker in any matter.

12. This Agreement may be executed in one or more counterparties, each of which shall be deemed to be an original and all of which taken together shall be deemed to constitute one and the same agreement.

13. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been duly given if (i) delivered personally to the recipient, (ii) sent to the recipient by reputable express courier service (charges prepaid) or mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, or (iii) transmitted by telecopy to the recipient with a confirmation copy to follow the next day to be delivered by overnight carrier.
