The Investor is able to bear the economic risk of an investment in the Purchased Common Stock and, at the present time, is able to afford a complete loss of such investment.

(e) Access to Information. The Investor acknowledges that it has reviewed the Disclosure Materials and has been afforded: (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Common Stock and the merits and risks of investing in the Common Stock; (ii) access to information (other than material non-public information) about the Company and the Subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment.

(f) No Governmental Review. The Investor understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Common Stock or the fairness or suitability of the investment in the Common Stock nor have such authorities passed upon or endorsed the merits of the offering of the Common Stock.

(g) No Legal, Tax or Investment Advice. The Investor understands that nothing in this Agreement or any other materials presented by or on behalf of the Company to the Investor in connection with the Purchased Common Stock constitutes legal, tax or investment advice.

OTHER AGREEMENTS OF THE PARTIES

5.1 Investor Director.

(a) Prior to the Closing, the Company and the Company’s Board of Directors shall take such action as may be necessary (including seeking any necessary vote or approval of any stockholder of the Company, taking any action necessary to expand the size of the Company’s Board of Directors, or causing any existing director to resign) in order to make a Board seat available for one individual designated by the Investor (the “Investor Director”), who shall initially be Xxxxxxx X. Xxxxxx, and to cause the Investor Director to be appointed at the Closing as a Class II member of the Company’s Board of Directors and any applicable committee thereof. The individual designated by the Investor to replace the initial Investor Director from time to time shall be reasonably acceptable to a majority of the independent members of the Company’s Board of Directors in their sole reasonable discretion (excluding then current Investor Director).

(b) For so long as the Investor together with its Affiliates beneficially owns both (i) in excess of 50% of the Purchased Common Stock, and (ii) 5% or more of the aggregate issued and outstanding shares of the Common Stock (the “Threshold Ownership Requirement”): the Company shall use all commercially reasonable best efforts (including, but not limited to, the taking of the actions set forth in this Section 5.1(b)) to cause the Investor Director to be maintained as a Class II member of the Company’s Board of Directors, such actions to include recommending to shareholders of the Company at which the election or removal of members of the Company’s Class

II members of the Board of Directors is on the agenda; provided, however, that parties agree and acknowledge that such actions shall not include authorizing a new class of stock or creating any special voting rights. In addition, Dr. Xxxx Xxxxxxx shall enter into a voting agreement, in the form of Exhibit B, which shall provide that he shall vote any shares of Common Stock beneficially owned by him in favor of the election of the Investor Director as a Class II member of the Company’s Board of Directors during such time as the Investor maintains the Threshold Ownership Requirement.

(c) The Investor Director will be accorded no less favorable treatment than any other Class II member of the Company’s Board of Directors with respect to all matters, including, without limitation, expense reimbursement and indemnification, membership on committees (it being agreed that for such purposes, the Investor Director shall be given the same consideration regarding membership as all other members of the Company’s Board of Directors) and reasonable access to Company information and management, except that the Investor Director may be excluded from participation or deliberation by the Company’s Board of Director or committees thereof in connection with issues involving: (i) interpretations of the Collaboration and License Agreement or any other agreements between the Company and the Investor (as reasonably determined by the Company’s Board of Directors or relevant committee thereof), (ii) matters of conflict or dispute between the Company and the Investor, or (iii) any other matter between the Company and a third party which is confidential and in the reasonable determination of the Company’s Board of Directors, would be compromised by the presence of the Investor Director due to such Investor Director’s affiliation with the Investor.

(d) Notwithstanding the foregoing, in the event that the Investor Director is sitting on a committee of the Company’s Board of Directors, and should the Investor Director not meet the independence requirements for membership on such committee, as determined by the Company’s Board of Directors in accordance with the Trading Market rules and the rules promulgated by the Commission that may be applicable to such a committee from time to time, the Investor Director shall have the right, except as provided for below, to attend such committee meetings as an observer for as long as such period as the Company’s Board of Directors intended the Investor Director to otherwise have been a member of such a committee. The Investor Director shall be notified of any meeting of the committee, including such meeting’s time and place, in the same manner as the committee members and shall have the same access to information concerning the business and operations of the Company and at the same time as members of the committee and shall be entitled to participate in discussions and consult with, and make proposals and furnish advice to, the committee, without voting; provided, however, the Investor Director shall not be entitled to participate in committee meetings attended exclusively by committee members and such committee shall be under no obligation to take any action with respect to any proposals made or advice furnished by the Investor Director, other than to give due consideration thereto. The parties hereby acknowledge that as of the date hereof, the Investor Director will not be independent under the relevant Trading Market rules and the rules promulgated by the Commission for the purpose of sitting on the Audit Committee of the Company’s Board of Directors and the Compensation Committee of the Company’s Board of Directors.

5.2 Actions Requiring Investor Director Approval. For so long as the Threshold Ownership Requirement is maintained, prior written approval of the Investor Director is required for

the following Company actions: (i) increasing the number of authorized directors of the Company’s Board of Directors to more than nine; (ii) except for preferred stock issued or issuable pursuant to a stockholders rights plan or convertible debt issued by the Company, issuance of any form of preferred stock prior to the third anniversary of the Closing Date, or (iii) entering into any material agreement that would, in the exercise of reasonable business judgment of the independent members of the Company’s Board of Directors excluding the Investor Director, materially impair or restrict the Company’s ability to fulfill its obligations under the terms of the Collaboration and License Agreement.

5.3 Right of First Offer.

(a) Subject to the terms and conditions set forth below, until the earlier of the termination of the Threshold Ownership Requirement or the third anniversary of the Closing Date, the Investor shall have the right to purchase, on a pro rata basis, any Common Stock or securities exchangeable for, exercisable for, or convertible into Common Stock (Common Stock and any such securities, “Pre-Emptive Shares”) which the Company may, from time to time, propose to issue and sell in an offering that is exempt from the registration requirements of the Securities Act (other than the issuance in connection with (i) the Company’s 2004 Equity Incentive Plan, the Company’s 2004 Employee Stock Purchase Plan, any other equity compensation or stock plan that may be properly approved and adopted by the Company from time to time, and any other equity issuances to employees, officers, directors, or consultants, (ii) acquisitions by the Company, or (iii) securities representing, in any one transaction or series of related transactions, less than 2% of the Company’s outstanding voting securities issued to banks, equipment lessors or other financial institutions pursuant to a commercial leasing or debt financing transactions, in connection with sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships, or securities issued to suppliers or third party service providers in connection with the provision of goods or services (collectively, clauses (i), (ii), and (iii) referred to as the “Exempt Securities”). The Investor’s pro rata share for purposes of this pre-emptive right, shall be determined by dividing (x) the total number of shares Common Stock owned by the Investor at such time, by (y) the total number of shares of Common Stock on a fully-diluted basis (assuming full exercise and/or conversion of all outstanding convertible securities, rights, options and warrants) at such time; provided, however, that the number of Pre-Emptive Shares issued to the Investor shall be limited such that the aggregate shares of (A) Purchased Common Stock, plus (B) Anti-Dilution Shares, plus (C) Pre-Emptive Shares, plus (D) any shares of the Common Stock purchased in the open market by the Investor will not exceed 19.9% of the aggregate issued and outstanding shares of the Common Stock determined both (i) as of the date hereof, and (ii) as of the time of any such issuance of Pre-Emptive Shares. The failure of the Investor to exercise its right of first offer with respect to any particular issuance shall not affect in any way such right with respect to any subsequent issuance.

(b) In the event the Company intends to issue any Pre-Emptive Shares, it shall give the Investor written notice (“First Offer Notice”) of such intention, describing the price of such Pre-Emptive Shares and the general terms upon with the Company proposes to effect the issuance. The Investor shall have twenty (20) days (unless a shorter period of time is agreed upon by the Investor) from the date of any such First Offer Notice to agree to purchase its pro rata share of such Pre-Emptive Shares for purchase price and upon the terms and conditions specified in the

Company’s First Offer Notice by giving written notice to the Company stating the quantity of Pre-Emptive Shares to be so purchased. In the event there is a material change in the terms upon which the Pre-Emptive Shares is offered by the Company following the delivery of the First Offer Notice, the Company will issue a new First Offer Notice and the Investor will have twenty (20) days from the date of issuance of the new First Offer Notice to deliver a new notice of acceptance to purchase the Pre-Emptive Shares on the new terms specified in such new First Offer Notice. In the event that any Pre-Emptive Shares are proposed to be issued to a third-party for non-cash consideration, the value of such Pre-Emptive Shares for the purpose of the Investor’s rights under this Section 5.3 shall be determined based on the ten-day trading average of the Common Stock as of the ten Trading Days immediately proceeding the First Offer Notice.

(c) If the Investor does not elect to purchase all of its pro rata share of the Pre-Emptive Shares so offered, the Company shall have the right to sell the unsold pro rata share of the Pre-Emptive Shares to any third party within ninety (90) days after the date of the First Offer Notice at a purchase price not less than, and upon the terms and conditions not more favorable than, the purchase price and terms and conditions set forth in the First Offer Notice. If the Company does not sell of the Pre-Emptive Shares within such ninety (90) day period, such Pre-Emptive Shares shall again be subject to the terms, conditions and restrictions set forth in this Section 5.3.

5.4 Anti-Dilution.

(a) In the event that the Company shall at any time (or from time to time) prior to the third anniversary of the Closing Date issue, grant, or sell any Common Stock (or securities exchangeable for, exercisable for, or convertible into, Common Stock) in an offering that is exempt from the registration requirements of the Securities Act (other the than issuance of Exempt Securities), for consideration per share of Common Stock (or underlying Common Stock) that is both (1) less than the Reference Price and (2) at least a 5% discount to the ten-day trading average of the Common Stock as of the ten Trading Days immediately proceeding such sale, then, on the date of any such issuance, the Company shall issue to the Investor, without any required additional consideration from by the Investor, additional shares of Common Stock (such shares, the “Anti-Dilution Shares”). The number of Anti-Dilution Shares to be issued by the Company to the Investor shall be calculated based on the formula set forth on Exhibit C hereto; provided, however, that the number of Anti-Dilution Shares issued to the Investor shall be limited such that the aggregate shares of (A) Purchased Common Stock, plus (B) Anti-Dilution Shares, plus (C) Pre-Emptive Shares, plus (D) any shares of the Common Stock purchased in the open market by the Investor will not exceed 19.9% of the aggregate issued and outstanding shares of the Common Stock determined both (i) as of the date hereof, and (ii) as of the time of any such anti-dilution adjustment.

(b) At such times, if any, as it becomes necessary to issue such Anti-Dilution Shares, the Company shall take all action necessary to authorize a number of shares of the authorized but unissued Common Stock sufficient to provide for the issuance of the Anti-Dilution Shares in accordance with the provisions of 5.4(a) above, and any such Anti-Dilution Shares shall be free from preemptive rights.

5.5 Transfer Restrictions.

(a) Lock Up Period. Prior to the earliest of (i) the third anniversary of the Closing Date, (ii) termination of the Collaboration and License Agreement, or (iii) failure of the Investor Director to be re-elected to the Company’s Board of Directors at the Company’s 2009 annual meeting (assuming that the Investor has informed the Company in a timely manner that the Investor Director will stand for re-election) (the “Lock Up Period”), the Purchased Common Stock may not be transferred by the Investor except: (i) to Affiliates of the Investor, provided that such Affiliate agrees to be subject to the restrictions on the Purchased Common Stock set forth in this Section 5.5(a) prior to the transfer and agrees to be bound by this Agreement and the Registration Rights Agreement and the obligations of the Investor contained therein and herein, or (ii) in connection with a Change of Control in which the Purchased Common Stock is converted or exchanged. Upon the expiration of the Lock Up Period, the Investor covenants that the Purchased Common Stock will only be disposed of pursuant to: (i) an available exemption from the registration requirements of the Securities Act, and in compliance with any Applicable Laws, (ii) the Registration Rights Agreement, or (iii) a sale to any Person approved by the majority of the independent members of the Company’s Board of Directors excluding the Investor Director.

(b) Sales. Notwithstanding the foregoing, the Investor shall not, without the consent of the Company’s Board of Directors, transfer any of the Purchased Common Stock to any Person, if, to the Investor’s actual knowledge, after reasonable inquiry (to the extent such inquiry is reasonably practicable), that transfer would result in that Person owning greater than 14.9% of the Company’s then outstanding shares of Common Stock.

(c) Legal Opinion. In connection with any permitted transfer of Purchased Common Stock other than pursuant to an effective registration statement or to the Company, or pursuant to Rule 144(k), the Company may require the transferor to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration under the Securities Act. Notwithstanding the foregoing, the Company hereby consents to and agrees to register on the books of the Company and with its transfer agent, without any such legal opinion, except to the extent that the transfer agent requests such legal opinion, any transfer of Purchased Common Stock by the Investor to an Affiliate of the Investor, provided that the transferee certifies to the Company that it is an “accredited investor” as defined in Rule 501(a) under the Securities Act and provided that such Affiliate does not request any removal of any existing legends on any certificate evidencing the Purchased Common Stock and provided that such Affiliate agrees to be bound by this Agreement and the Registration Rights Agreement.

(d) Legend. The Investor agrees to the imprinting, so long as is required by this Section 5.5(d), of the following legend on any certificate evidencing Purchased Common Stock:

THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION

STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD, AND CERTAIN OTHER RESTRICTIONS, ALL AS SET FORTH IN CERTAIN DEFINITIVE AGREEMENTS BETWEEN THE COMPANY AND THE ORIGINAL HOLDERS OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.

Certificates evidencing Purchased Common Stock shall not be required to contain such legend or any other legend (i) after a transfer pursuant to a registration statement that is effective under the Securities Act covering the resale of such Purchased Common Stock, (ii) following any sale of such Purchased Common Stock pursuant to Rule 144, (iii) if such Purchased Common Stock are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act (including controlling judicial interpretations and pronouncements issued by the Staff of the Commission). At such time as a legend is no longer required for the Purchased Common Stock, the Company will no later than three Trading Days following the delivery by the Investor to the Company of a legended certificate representing such Common Stock and an opinion of counsel to the extent required by Section 5.5(c), deliver or cause to be delivered to the Investor a certificate representing such Purchased Common Stock that is free from all restrictive and other legends. The Company may not make any notation on its records that enlarge the restrictions on transfer set forth in this Section.

5.6 Significant Events.

(a) Competitors. If, at any time prior to the third anniversary of the Closing Date, any Person listed on the List of Specific Persons beneficially owns 20% or more of the outstanding voting securities of the Company in a circumstance that does not constitute a Change of Control, then:

(i) the Company shall immediately become obligated to file a shelf registration statement for the benefit of the Investor and any of its transferees in accordance with the terms of the Registration Rights Agreement;

(ii) the Lock Up Period shall automatically terminate; and

(iii) the Investor shall have the right, at its option, and without limitation of its other rights under the Collaboration and License Agreement, to immediately, upon written notice, terminate the Collaboration and License Agreement in accordance with Section 8.2.1(c) thereof.

(b) Departure of Xx. Xxxxxxx. If, at any time prior to the third anniversary of the Closing Date, Dr. Xxxx Xxxxxxx, for reasons other than his death or disability, is no longer an officer or director of the Company, then:

(i) the Company shall immediately become obligated to file a shelf registration statement for the benefit of the Investor and its transferees in accordance with the terms of the Registration Rights Agreement;

(ii) the Lock Up Period shall automatically terminate; and

(iii) the Investor shall have the right, at its option, and without limitation of its other rights under the Collaboration and License Agreement to immediately, upon written notice, terminate the Collaboration and License Agreement in accordance with Section 8.2.1(c) thereof.

(c) Change of Control. If, at any time prior to the third anniversary of the Closing Date, there is a Change of Control of the Company, then:

(ii) the Lock Up Period shall automatically terminate; and

(iv) If the Change of Control occurs within twelve months after the Closing Date, and if the per share value of any merger consideration received by the Investor in such Change of Control for each share of Purchased Common Stock held by the Investor is to be less than the Reference Price, then the Company will provide in the definitive acquisition agreement in connection with such Change of Control that the acquirer shall pay to the Investor, in addition to the amount of merger consideration to which the Investor is otherwise entitled, an amount for each share of Purchased Common Stock held by the Investor equal to the amount by which the Reference Price exceeds the per share value of the merger consideration received by the Investor in such Change of Control for each share of Purchased Common Stock held by the Investor.

5.7 Standstill. (a) During the Initial Term (as such term is defined in the Collaboration and License Agreement), neither the Investor nor any of its Affiliates shall, unless and until it shall have received the prior written consent of the Company’s Board of Directors excluding the Investor Director, directly or indirectly (i) acquire, agree to acquire, make any public proposal to acquire, or cause any third-party to acquire any securities of the Company, any option to acquire any such securities, any security convertible into or exchangeable for any such securities or other right to acquire any such securities (except that this restriction shall not apply to (x) acquisitions of not more than one percent (1%) of the then-outstanding shares of the Common Stock in the aggregate during

the Initial Term, (y) acquisitions for the Investor’s qualified employee benefit plans, or (z) acquisitions of any Additional Shares, (ii) publicly propose any merger, consolidation, business combination, tender or exchange offer, sale or purchase of assets or securities, dissolution, liquidation, restructuring, recapitalization or similar transaction of or involving the Company, (iii) make, or in any way participate in, any solicitation of proxies or consents, as such terms are used in Regulation 14A under the Exchange Act, with respect to any securities of the Company, or seek to advise or influence any person with respect to the voting of any securities of the Company, or demand in connection with the foregoing, a copy of the stock ledger list of stockholders, or any other books and records of the Company, (iv) form, join or in any way participate in a “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any voting securities of the Company, (v) knowingly assist, induce or encourage any other Person or agree or offer to take, or knowingly encourage or propose (publicly or otherwise) or enter into any arrangements, understandings or agreements (whether written or oral) with, or advise, finance, or assist, any other persons in connection with any of the foregoing, or (vi) make any publicly disclosed proposal regarding the foregoing.

(b) The Company represents that it has not previously entered into a similar agreement that contains standstill provisions that, in the good faith reasonable judgment of the independent members of the Company’s Board of Directors, are more favorable to, or less restrictive upon, the other party to such agreement than the provisions set forth in Section 5.7(a) in any material respect, after taking into account the standstill in the context of such other transaction as a whole (a “Subject Standstill Transaction”). The parties agree that if the Company has previously entered into, or subsequently enters into (or amends, waives any provision of, or fails to enforce any provision of promptly after learning of the breach thereof) an agreement that evidences a Subject Standstill Transaction with another party, then the Company shall promptly (and in any event within five (5) Trading Days) provide the Investor written notice of the terms thereof (without identifying the other party). If any standstill provisions in a Subject Standstill Transaction applicable to the other party are, in the good faith reasonable judgment of the independent members of Company’s Board of Directors, more favorable to, or less restrictive upon, the other party than the provisions set forth in Section 5.7(a) in any material respect when taking into consideration this transaction as a whole and the Subject Standstill Transaction as a whole, then the parties shall use commercially reasonable efforts to amend Section 5.7(a) to conform (such conforming to be as close to such Subject Standstill Transaction as is reasonably practicable to implement) to such more favorable or less restrictive provisions, and the Company shall promptly provide the Investor written notice of such amendment (without identifying the other party).

5.8 Securities Laws Disclosure; Publicity. The Company shall (i) on or before 8:30 a.m., New York time, on the first Trading Day following the execution of this Agreement, issue a press release reasonably acceptable to the Investor disclosing the transaction contemplated hereby, (ii) on the first Trading Day following the execution of this Agreement, file a Current Report on Form 8-K with the Commission (the “Form 8-K Filing”) describing the terms of the transactions contemplated by the Transaction Documents, which also shall attach the Transaction Documents to the Form 8-K Filing as exhibits, redacting all information reasonably requested to be redacted by the Investor from such Transaction Documents as may be permitted by Applicable Law, and (iii) on the first Trading Day following the execution of this Agreement, hold a teleconference for analysts and investors. The Company and the Investor shall consult with each other in issuing any other press release or

otherwise making any other public statements with respect to such transactions contemplated hereby, and neither party shall issue such press release(s) or otherwise make any such public statement(s) without the prior consent of the other, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement.

5.9 Integration. The Company shall not, and shall use its best efforts to ensure that no Affiliate thereof shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Purchased Common Stock in a manner that would require the registration under the Securities Act of the sale of the Purchased Common Stock to the Investor or that would be integrated with the offer or sale of the Purchased Common Stock for purposes of the rules and regulations of any Trading Market. If the issuance to the Investors of Additional shares could cause the provisions of Section 203 of the Delaware General Corporation Law, as it may be amended from time to time, to be applicable to the Investor, then the Company shall take all action reasonably necessary to avoid such application, including granting Investor all necessary or appropriate waivers.

5.10 Use of Proceeds. The Company intends to use the net proceeds from the sale of the Purchased Common Stock for general corporate purposes, including growth initiatives and capital expenditures.

Promptly after the Company or the Investor (hereafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action or proceeding, but failure to notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability, provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense and employ counsel or (B) the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnifying Party of if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in such defense or such action, with the expenses and fees of such separate counsel or other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release of liability of, the Indemnified Party.

(d) Survival. The representations and warranties, made in this Agreement shall survive any investigation made by any party hereto and the Closing for a period of twelve months. All covenants and agreements contained herein shall survive until, by their respective terms, they are fully performed and no longer operative.

8.2 Fees and Expenses. Each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all stamp taxes and other taxes and duties levied in connection with the sale and issuance of their applicable Common Stock.

8.3 Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules. At or after the Closing, and without further consideration, the Company will execute and deliver to the Investor such further documents as may be reasonably requested in order to give practical effect to the intention of the parties under the Transaction Documents.

8.4 Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section prior to 6:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section on a day that is not a Trading Day or later than 6:30 p.m. (New York City time) on any Trading Day, (c) the Trading Day following the date of deposit with a nationally recognized overnight courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The addresses and facsimile numbers for such notices and communications are those set forth on the signature pages hereof, or such other address or facsimile number as may be designated in writing hereafter, in the same manner, by any such Person.

8.5 Amendments; Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed, in the case of an amendment, by the Company and the Investor or, in the case of a waiver, by the party against whom enforcement of any such waiver is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

8.6 Construction. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

8.7 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Investor. The Investor may assign its rights under this Agreement to any Person to whom the Investor assigns or transfers any Purchased Common Stock, provided such transferee agrees in writing to be bound, with respect to the transferred Purchased Common Stock, by the provisions hereof that apply to the “Investor.”

8.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

8.9 Governing Law; Venue; Waiver of Jury Trial. THIS AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS BY THE INTERNAL LAWS OF THE STATE OF DELAWARE AS APPLIED TO AGREEMENTS ENTERED INTO AMONG DELAWARE RESIDENTS TO BE PERFORMED ENTIRELY WITHIN DELAWARE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. THE COMPANY AND INVESTORS HEREBY IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING IN THE CITY OF NEW YORK, BOROUGH OF MANHATTAN FOR THE ADJUDICATION OF ANY DISPUTE BROUGHT BY THE COMPANY OR ANY INVESTOR HEREUNDER, IN CONNECTION HEREWITH OR WITH ANY TRANSACTION CONTEMPLATED HEREBY OR DISCUSSED HEREIN (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THE TRANSACTION DOCUMENTS), AND HEREBY IRREVOCABLY WAIVE, AND AGREE NOT TO ASSERT IN ANY SUIT, ACTION OR PROCEEDING BROUGHT BY THE COMPANY OR ANY INVESTOR, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT, OR THAT SUCH SUIT, ACTION OR PROCEEDING IS IMPROPER. EACH PARTY HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR PROCEEDING BY MAILING A COPY THEREOF VIA REGISTERED OR CERTIFIED MAIL OR OVERNIGHT DELIVERY (WITH EVIDENCE OF DELIVERY) TO SUCH PARTY AT THE ADDRESS IN EFFECT FOR NOTICES TO IT UNDER THIS AGREEMENT AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE GOOD AND SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF. NOTHING CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW. THE COMPANY AND INVESTORS HEREBY WAIVE ALL RIGHTS TO A TRIAL BY JURY.

8.10 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

8.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

8.12 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever the Investor exercises a right, election, demand or option owed to the Investor by the Company under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then, prior to the performance by the Company of the Company’s related obligation, the Investor may rescind or withdraw, in its sole discretion from time to time upon written notice to such seller, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

8.13 Replacement of Common Stock. If any certificate or instrument evidencing any Common Stock is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company for any losses in connection therewith. The applicants (and not the Company) for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Common Stock, including the payment of any insurance bond or other fee required for such replacement certificate.

8.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Investor and the Company will be entitled to seek specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation (other than in connection with any action for temporary restraining order) the defense that a remedy at law would be adequate.

8.15 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in share of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly share of Common Stock), combination or other similar recapitalization or event occurring after the date hereof, each reference in any Transaction Document to a number of shares or a price per share shall be amended to appropriately account for such event.

Execution Copy

Exhibit B

Anti-Dilution Formula

The number of Anti-Dilution Shares issued to the Investor = X, where:


X	=	95,000,000	-	95,000,000
		NR		R

R	=	$29.629

NR	=	(R) x (F)

F	=	CS1 + CS$
		CS2


CS1	=	aggregate number of shares of Common Stock outstanding immediately before the issuance, grant or sale that triggers the Investor’s anti-dilution rights pursuant to Section 5.4 of the Agreement (a “Dilutive Issuance” and the securities issued in such Dilutive Issuance the “Dilution Shares”).

CS$	=	number of shares of Common Stock which the aggregate consideration received by the Company for the Dilution Shares would purchase at $29.629 per share.

CS2	=	aggregate number of shares of Common Stock outstanding immediately following the Dilutive Issuance.

Example

For illustrative purposes only, the following is an example of the application of the formula set forth above based on a hypothetical set of facts:

Facts:

•

The Company makes a Dilutive Issuance of 3,800,000 Common Shares at $12.50 per share, for an aggregate of $47,500,000.

•

The aggregate number of shares of Common Stock outstanding immediately before the Dilutive Issuance is 28,421,130.

Adjustment:


F =	28,421,130 + 1,603,159	=	0.93
	32,221,130

NR = (29.629)(0.93) = 27.555


Anti Dilution Shares	=	95,000,000	-	95,000,000	=	241,332
		27.555		29.629
