(d) The Registration Statement, at the time it became effective, as of the date hereof, and at the Closing Date conformed and will conform in all material respects to the requirements of the Act and the Rules and Regulations. The Preliminary Prospectus conformed, and the Prospectus will conform, when filed with the Commission pursuant to Rule 424(b) and on the Closing Date to the requirements of the Act and the Rules and Regulations.

(i) Each Issuer Free Writing Prospectus, when considered together with the Pricing Disclosure Materials as of the Applicable Time, did not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representation or warranty with respect to any statement contained in the Issuer Free Writing Prospectus in reliance upon and in conformity with information concerning a Placement Agent and furnished in writing by such Placement Agent to the Company expressly for use in the Issuer Free Writing Prospectus, as set forth in Section 8(b).

The Company has not made any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Placement Agents. The Company has retained in accordance with the Rules and Regulations all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Rules and Regulations.

(k) The Company is, and at the Closing Date will be, duly organized, validly existing and in good standing under the laws of the State of Delaware. The Company (i) has, and at the Closing Date will have, full power and authority to conduct all the activities conducted by it, to own or lease all the assets owned or leased by it and to conduct its business as described in the Registration Statement and the Prospectus and (ii) is, and at the Closing Date will be, duly licensed or qualified to do business and in good standing as a foreign organization in all jurisdictions in which the nature of the activities conducted by it or the character of the assets owned or leased by it makes such licensing or qualification necessary; except, in each case, where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, have a material adverse effect or

would not reasonably be expected to have a material adverse effect on or affecting the business, properties, management, consolidated financial position, stockholders’ equity or results of operations of the Company and its Subsidiaries (as defined below) taken as a whole. Complete and correct copies of the articles or certificate of incorporation and of the bylaws of the Company and all amendments thereto have been delivered or made available to the Placement Agents, and no changes therein will be made subsequent to the date hereof and prior to the Closing Date.

(l) The Company’s only subsidiaries (each a “Subsidiary” and collectively the “Subsidiaries”) are listed on Schedule 1 to this Agreement. Each Subsidiary has been duly organized and is validly existing as a corporation in good standing under the laws of its jurisdiction of formation. Each Subsidiary is duly qualified and in good standing as a foreign corporation in each jurisdiction in which the character or location of its properties (owned, leased or licensed) or the nature or conduct of its business makes such qualification necessary, except for those failures to be so qualified or in good standing which will not, individually or in the aggregate, have a material adverse effect on the business, properties, management, consolidated financial position, stockholders’ equity or results of operations of the Company and its Subsidiaries taken as a whole (a “Material Adverse Effect”). All of the shares of issued capital stock of each subsidiary of the Company have been duly authorized and validly issued, are fully paid and non-assessable and are owned directly or indirectly by the Company, free and clear of any lien, encumbrance, claim, security interest, restriction on transfer, shareholders’ agreement, voting trust or other defect of title whatsoever.

The descriptions of the securities of the Company in the Registration Statement and the Prospectus are, and at the Closing Date will be, complete and accurate in all respects. Except as set forth in the Registration Statement and the Prospectus, the Company does not have outstanding any rights (other than stock options or other equity awards under the Company’s equity incentive and stock purchase plans) or warrants to subscribe for, or any securities or obligations convertible into, or exchangeable for, or any contracts or commitments to issue or sell, any shares of capital stock or other securities.

(n) The Company has full legal right, power and authority to enter into this Agreement and the proposed purchase agreements to be executed by each Investor and the Company, substantially in the form attached hereto as Exhibit A (the “Investor Purchase Agreements,” and together with this Agreement, the “Transaction Documents”) and perform the transactions contemplated hereby and thereby. The Transaction Documents have been authorized and validly executed and delivered by the Company and are legal, valid and binding agreements of the Company enforceable against the Company in accordance with their respective terms, subject to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and equitable principles of general applicability.

(o) The issuance and sale of the Shares have been duly authorized by the Company, and the Shares, when issued and paid for in accordance with the Transaction Documents, will be duly and validly issued, fully paid and nonassessable and will not be

subject to preemptive or similar rights. The holders of the Shares will not be subject to personal liability by reason of being such holders. The Shares, when issued, will conform in all material respects to the description thereof set forth in or incorporated into the Prospectus.

(p) The consolidated financial statements and the related notes included in the Registration Statement and the Prospectus present fairly, in all material respects, the financial condition of the Company and its consolidated Subsidiaries as of the dates thereof and the results of operations and cash flows at the dates and for the periods covered thereby in conformity with generally accepted accounting principles (“GAAP”). No other financial statements or schedules of the Company, any Subsidiary or any other entity are required by the Act or the Rules and Regulations to be included in the Registration Statement or the Prospectus. All disclosures contained in the Registration Statement, the Pricing Disclosure Materials and the Prospectus regarding “non-GAAP financial measures” (as such term is defined by the Rules and Regulations) comply with Regulation G of the Exchange Act and Item 10 of Regulation S-K under the Act, to the extent applicable. The Company and the Subsidiaries do not have any material liabilities or obligations, direct or contingent (including any off-balance sheet obligations or any “variable interest entities” within the meaning of Financial Accounting Standards Board Interpretation No. 46), not disclosed in the Registration Statement, the Pricing Disclosure Materials and the Prospectus.

(q) Ernst & Young LLP (the “Accountants”), who have reported on such consolidated financial statements and schedules, are registered independent public accountants with respect to the Company as required by the Act and the Rules and Regulations and by the rules of the Public Accounting Oversight Board.

(r) Except as set forth in the Registration Statement and the Prospectus, there is and has been no failure on the part of the Company, or to its knowledge after due inquiry, any of the Company’s directors or officers, in their capacities as such, to comply with any applicable provisions of the Sarbanes Oxley Act of 2002 and the rules and regulations promulgated therewith (the “Sarbanes Oxley Act”). Each of the principal executive officer and the principal financial officer of the Company (or each former principal executive officer of the Company and each former principal financial officer of the Company as applicable) has made all certifications required by Sections 302 and 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act with respect to all reports, schedules, forms, statements and other documents required to be filed by it with the Commission.

(iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and its Subsidiaries is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by the Form 10-K for the year ended December 31, 2006 (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the year ended December 31, 2006 the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date.

(t) Except as set forth in or otherwise contemplated by the most recent Preliminary Prospectus, since the date of the most recent consolidated financial statements of the Company included or incorporated by reference in the most recent Preliminary Prospectus and prior to Closing, (i) there has not been and will not have been any change in the capital stock of the Company or long-term debt of the Company or any Subsidiary or any dividend or distribution of any kind declared, set aside for payment, paid or made by the Company on any class of capital stock, or any material adverse change, in the business, properties, management, consolidated financial position, stockholders’ equity, or results of operations of the Company and its Subsidiaries taken as a whole (a “Material Adverse Change”) and (ii) neither the Company nor any Subsidiary has sustained or will sustain any material loss or material interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor disturbance or dispute or any action, order or decree of any court or arbitrator or governmental or regulatory authority, except in each case as otherwise disclosed in the Registration Statement and the Prospectus.

(a) The Registration Statement has become effective, and if Rule 430A is used or the filing of the Prospectus is otherwise required under Rule 424(b), the Company will file the Prospectus (properly completed if Rule 430A has been used), subject to the prior approval of the Placement Agents, pursuant to Rule 424(b) within the prescribed time period and will provide a copy of such filing to the Placement Agents promptly following such filing.

(b) The Company will not, during such period as the Prospectus would be required by law to be delivered in connection with sales of the Shares by an underwriter or dealer in connection with the offering contemplated by this Agreement, file any amendment or supplement to the Registration Statement or the Prospectus unless a copy thereof shall first have been submitted to the Placement Agents within a reasonable period of time prior to the filing thereof and the Placement Agents shall not have reasonably objected thereto in good faith.

(d) If, at any time when a Prospectus relating to the Shares is required to be delivered under the Act, the Company becomes aware of the occurrence of any event as a result of which the Prospectus, as then amended or supplemented, would, in the reasonable judgment of counsel to the Company or counsel to the Placement Agents, include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or the Registration Statement, as then amended or supplemented, would, in the reasonable judgment of counsel to the Company or counsel to the Placement Agents, include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading, or if for any other reason it is necessary, in the reasonable judgment of counsel to the Company or counsel to the Placement Agents, at any time to amend or supplement the Prospectus or the Registration Statement to comply with the Act or the Rules and Regulations, the Company will promptly notify the Placement Agents and, subject to Section 4(b) hereof, will promptly prepare and file with the Commission, at the Company’s expense, an amendment to the Registration Statement or an amendment or supplement to the

Prospectus that corrects such statement or omission or effects such compliance and will deliver to the Placement Agents, without charge, such number of copies thereof as the Placement Agents may reasonably request. The Company consents to the use of the Prospectus or any amendment or supplement thereto by the Placement Agents.

Each Placement Agent severally agrees that it shall not include any “issuer information” (as defined in Rule 433 under the Act) in any “free writing prospectus” (as defined in Rule 405) used or referred to by such Placement Agent without the prior consent of the Company (any such issuer information with respect to whose use the Company has given its consent, “Permitted Issuer Information”). The Placement Agents also agree to provide to each Investor, prior to the Closing, a copy of the Prospectus and any amendments or supplements thereto.

8. Indemnification.

(a) The Company shall indemnify and hold harmless the Placement Agents, their respective directors, officers, employees and agents and each person, if any, who controls any of the Placement Agents within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, liabilities, expenses and damages, joint or several, (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which it, or any of them, may become subject under the Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on (i) any untrue statement or alleged untrue statement made by the Company in Section 3 of this Agreement, (ii) any untrue statement or alleged untrue statement of any material fact contained in (A) any Preliminary Prospectus, the Registration Statement or the Prospectus or any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or any amendment or supplement thereto or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405) used or referred to by the Placement Agents and (D) any application or other document, or any amendment or supplement thereto, executed by the Company based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Shares under the securities or Blue Sky laws thereof or filed with the Commission or any securities association or securities exchange (each, an “Application”), or (iii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or in any Permitted Issuer Information or any Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person and is based solely on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Placement Agents furnished in writing to the Company by the Placement Agents expressly for inclusion in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information or any Application (as set forth in Section 8(b) below); and provided further, that such indemnity with respect to any Preliminary Prospectus, Issuer Free Writing Prospectus or any Permitted Issuer Information shall not inure to the benefit of the Placement Agents (or any person controlling any of the Placement Agents) from whom the person asserting any such loss, claim, damage, liability or action purchased Shares which are the subject thereof to the extent that any such loss, claim, damage or liability (i) results from the fact that the Placement Agents failed to send or give a copy of the Prospectus (as amended or supplemented) to such person at or prior to the

confirmation of the sale of such Shares to such person in any case where such delivery is required by the Act and (ii) arises out of or is based upon an untrue statement or omission of a material fact contained in such Preliminary Prospectus, Issuer Free Writing Prospectus or any Permitted Issuer Information that was corrected in the Prospectus (or any amendment or supplement thereto), unless such failure to deliver the Prospectus (as amended or supplemented) was the result of noncompliance by the Company with Section 4(d). This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) The Placement Agents will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signs the Registration Statement to the same extent as the foregoing indemnity from the Company to the Placement Agents, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to the Placement Agents furnished in writing to the Company by the Placement Agents expressly for use in the Registration Statement, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity agreement will be in addition to any liability that the Placement Agents might otherwise have. The Company acknowledges that, for all purposes under this Agreement, the name of the Placement Agents and the paragraph relating to placement agents’ fees and reimbursement of expenses appearing under the caption “Plan of Distribution” in the Prospectus constitute the only information relating to the Placement Agents furnished in writing to the Company by the Placement Agents expressly for inclusion in the Registration Statement, any Preliminary Prospectus or the Prospectus.

(c) Any party that proposes to assert the right to be indemnified under this Section 8 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 8, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this Section 8 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of counsel) that a conflict exists (based on advice of

counsel to the indemnified party) between the indemnified party and the indemnifying party that would prevent the counsel selected by the indemnifying party from representing the indemnified party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (3) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. The indemnifying party will not, without the prior written consent of the indemnified party (which consent will not be unreasonably withheld), settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification has been sought hereunder, unless such settlement, compromise or consent includes an unconditional release of the indemnified party from all liability arising out of such claim, action, suit or proceeding. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld).

(d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 8 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Placement Agents, the Company and the Placement Agents will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Placement Agents such as persons who control the Company within the meaning of the Act or the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and the Placement Agents may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agents on the other. The relative benefits received by the Company on the one hand and the Placement Agents on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting Company expenses) received by the Company as set forth in the table on the cover page of the Prospectus bear to the fee received by the Placement Agents hereunder. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Placement Agents on the other, with respect to the statements or omissions which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Placement Agents, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent

such statement or omission. The Company and the Placement Agents agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purpose of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), the Placement Agents shall not be required to contribute any amount in excess of the fee received by it, and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8(d), any person who controls a party to this Agreement within the meaning of the Act or the Exchange Act will have the same rights to contribution as that party, and each officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 8(d), will notify any such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 8(d). No party will be liable for contribution with respect to any action or claim settled without its written consent (which consent will not be unreasonably withheld).

9. Termination.

(a) The obligations of the Placement Agents under this Agreement may be terminated at any time prior to the Closing Date, by notice to the Company from the Placement Agents, without liability on the part of the Placement Agents to the Company if, prior to delivery and payment for the Shares, in the sole judgment of the Placement Agents (i) trading in the Common Stock of the Company shall have been suspended by the Commission or by the NASDAQ Global Market, (ii) trading in securities generally on the NASDAQ Global Market shall have been suspended or limited or minimum or maximum prices shall have been generally established on any of such exchange or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by any of such exchange or by order of the Commission or any court or other governmental authority, (iii) a general banking moratorium shall have been declared by Federal or New York State authorities, or (iv) any material adverse change in the financial or securities markets in the United States or any outbreak or material escalation of hostilities or declaration by the United States of a national emergency or war or other calamity or crisis shall have occurred, the effect of any of which is such as to make it, in the sole judgment of the Placement Agents, impracticable or inadvisable to market the Shares on the terms and in the manner contemplated by the Prospectus.

(b) If this Agreement shall be terminated pursuant to any of the provisions hereof, or if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Placement Agents set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any

agreement herein or comply with any provision hereof, the Company will, subject to demand by the Placement Agents, reimburse the Placement Agents for all out-of-pocket expenses incurred in connection herewith in an aggregate amount not to exceed $75,000.

10. No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, sale of the Shares or any other services the Placement Agents may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Placement Agents: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Placement Agents, on the other, exists; (ii) the Placement Agents are not acting as advisors, experts or otherwise, to the Company, including, without limitation, with respect to the determination of the offering price of the Shares, and such relationship between the Company, on the one hand, and the Placement Agents, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Placement Agents may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Placement Agents and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Placement Agents with respect to any breach of fiduciary duty in connection with this offering.

Ladies and Gentlemen:

The undersigned understands that you, as Placement Agents, propose to enter into a Placement Agency Agreement (the “Placement Agency Agreement”) with Sequenom, Inc., a Delaware corporation (the “Company”), providing for an offering (the “Offering”) of shares of the Company’s Common Stock. Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Placement Agency Agreement.

In consideration of the foregoing, and in order to induce you to act as Placement Agents in the Offering, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of ▇▇▇▇▇▇ Brothers Inc., the undersigned will not, during the period beginning on the date hereof and ending on the date which is 90 days after the date of the final prospectus supplement relating to the Offering, (1) offer for sale, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), or (2) enter into any swap or other agreement that transfers to another, in whole or in part, any of the economic consequences of ownership of such shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise.

Notwithstanding the foregoing, the restrictions set forth in clause (1) and (2) above shall not apply to (a) transfers (i) as a bona fide gift or gifts to any charitable organization, (ii) as a bona fide gift or gifts to any other entity or person, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (iii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iv) with the prior written consent of ▇▇▇▇▇▇ Brothers Inc., or (b) the acquisition or exercise of any stock option issued pursuant to the Company’s existing stock option plans, including any exercise

effected by the delivery or sale of shares of Common Stock of the Company held by the undersigned. Notwithstanding the foregoing, nothing contained in this letter agreement shall prohibit the undersigned from establishing a trading plan pursuant to Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, provided that the undersigned shall not engage in any transaction under such trading plan until the termination of the restrictions imposed by this letter agreement. For purposes of this letter agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

Notwithstanding the above, to the extent you are at such time providing research coverage to the Company and subject to the restrictions set forth in NASD Rule 2711(f)(4), then, if (1) during the last 17 days of the lock-up period, (A) the Company issues an earnings release or (B) material news or a material event relating to the Company occurs; or (2) prior to the expiration of the lock-up period, the Company announces that it will release earnings results during the 16-day period following the last day of the lock-up period, then the restrictions imposed by this letter agreement shall continue to apply until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of material news or a material event relating to the Company, as the case may be, unless ▇▇▇▇▇▇ Brothers Inc. or ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇, LLC, as applicable, waives, in writing, such extension.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this letter agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this letter agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

Notwithstanding the foregoing, the restrictions set forth in this letter agreement shall not apply to (a) securities required to be issued pursuant to contractual obligations of the Company in effect as of the date of this letter agreement and disclosed to the Placement Agents or its counsel prior to the Closing; (ii) securities issued on a pro rata basis to all holders of a class of outstanding equity securities of the Company; (iii) securities issued in connection with a strategic partnership, licensing, joint venture, collaboration, lending or other similar arrangements, or in connection with the acquisition or license by the Company of any business, products or technologies, so long as the aggregate amount of such issuances pursuant to this clause (iii) does not exceed 10% of the Company’s outstanding capital stock measured as of the closing of the sale of the Shares, including the Shares; and (iv) equity securities issued pursuant to employee benefit or purchase plans described or incorporated by reference in the Registration Statement, the Preliminary Prospectus or the Prospectus.
