Under no circumstances shall the Company be obligated to effect more than an aggregate of (i) two (2) Registrations pursuant to a Demand Registration under this subsection 2.1.1 initiated by New Holders, or (iii) two (2) Registration pursuant to a Demand Registration under this subsection 2.1.1 initiated by Perceptive Holders.

2.1.2 Effective Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, however, that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency, the Registration Statement with respect to such Registration shall be deemed not to have been declared effective for purposes of counting Registrations under subsection 2.1.1 above unless and until (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; provided, further, however, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or has been terminated.

2.1.3 Underwritten Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, if a majority-in-interest of the Demanding Holders advise the Company as part of their Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Demand Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein.

A majority-in-interest of the New Holders or a majority-in-interest of the Perceptive Holders, as the case may be, in the case of a Registration under subsection 2.1.1 initiated by the New Holders or the Perceptive Holders, as the case may be, or a majority-in-interest of the Demand Requesting Holders (if any) shall have the right to withdraw from a Registration pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter(s) (if any) of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration (or after such Registration Statement has been declared effective and is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency). In the event of such withdrawal the Holders shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5, unless the Holders of a majority of the Registrable Securities agree to forfeit their right to a demand registration pursuant to Section 2.1.

Section 2.2. Piggyback Registration.

2.2.1 Piggyback Rights. If the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (other than pursuant to Sections 2.1 and 2.3 of this Agreement), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) filed on Form S-4 related to any merger, acquisition or business combination, or (v) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter(s), if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its commercially reasonable efforts to cause the managing Underwriter(s) of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this subsection 2.2.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. Al such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.2.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company.

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter(s) in an Underwritten Registration that is to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of shares of Common Stock that the Company desires to sell, taken together with (i) the shares of Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2.1 hereof, and (iii) the shares of Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(i)

If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1 hereof, Pro Rata, based on the respective number of Registrable Securities that each Holder has so requested, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities; and

(ii)

If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1, Pro Rata based on the respective number of Registrable Securities that each Holder has requested, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

2.2.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration, or, if such Piggyback Registration is in connection with an underwritten offering pursuant to an effective shelf registration statement, then prior to the public announcement of such offering. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.2.3.

The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder of Registrable Securities has elected to include securities in such registration.

Section 2.3. Resale Shelf Registration Rights

2.3.1 Registration Statement Covering Resale of Registrable Securities. The Company shall prepare and file or cause to be prepared and filed with the Commission, no later than forty-five (45) days following the Closing Date (the “Filing Deadline”), a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 of the Securities Act or any successor thereto registering the resale from time to time by Holders of all of the Registrable Securities held by the Holders (the “Resale Shelf Registration Statement”). The Resale Shelf Registration Statement shall be on Form S-3 (or, if Form S-3 is not available to be used by the Company at such time, on Form S-1 or another appropriate form permitting Registration of such Registrable Securities for resale). If the Resale Shelf Registration Statement is initially filed on Form S-1 and thereafter the Company becomes eligible to use Form S-3 for secondary sales, the Company shall, as promptly as practicable, cause such Resale Shelf Registration Statement to be amended, or shall file a new replacement Resale Shelf Registration Statement, such that the Resale Shelf Registration Statement is on Form S-3. The Company shall use commercially reasonable efforts to cause the Resale Shelf Registration Statement to be declared effective as soon as possible after filing; provided, however, that the Company’s obligations to include the Registrable Securities held by a Holder in the Resale Shelf Registration Statement are contingent upon such Holder furnishing in writing to the Company such information regarding the Holder, the securities of the Company held by the Holder and the intended method of disposition of the Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, and the Holder shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations. Once effective, the Company shall use commercially reasonable efforts to keep the Resale Shelf Registration Statement and Prospectus included therein continuously effective and to be supplemented and amended to the extent necessary to ensure that such Registration Statement is available or, if not available, to ensure that another Registration Statement is available, under the Securities Act at all times until the earliest of (i) the date on which all Registrable Securities and other securities covered by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration Statement and (ii) the date on which all Registrable Securities and other securities covered by such Registration Statement have ceased to be Registrable Securities. The Registration Statement filed with the Commission pursuant to this subsection 2.3.1 shall contain a prospectus in such form as to permit any Holder to sell such Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) at any time beginning on the effective date for such Registration Statement (subject to lock-up restrictions provided in Section 5.1 of this Agreement), and shall provide that such Registrable Securities may be sold pursuant to any method or combination of methods legally available to, and requested by, Holders.

2.3.2 Notification and Distribution of Materials. The Company shall notify the Holders in writing of the effectiveness of the Resale Shelf Registration Statement as soon as practicable, and in any event within one (1) Business Day after the Resale Shelf Registration Statement becomes effective, and shall furnish to them, without charge, such number of copies of the Resale Shelf Registration Statement (including any amendments, supplements and exhibits), the Prospectus contained therein (including each preliminary prospectus and all related amendments and supplements) and any documents incorporated by reference in the Resale Shelf Registration Statement or such other documents as the Holders may reasonably request in order to facilitate the sale of the Registrable Securities in the manner described in the Resale Shelf Registration Statement.

2.3.3 Amendments and Supplements. Subject to the provisions of Section 2.3.1 above, the Company shall promptly prepare and file with the Commission from time to time such amendments and supplements to the Resale Shelf Registration Statement and Prospectus used in connection therewith as may be necessary to keep the Resale Shelf Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all the Registrable Securities. If any Resale Shelf Registration Statement filed pursuant to Section 2.3.1 is filed on Form S-3 and thereafter the Company becomes ineligible to use Form S-3 for secondary sales, the Company shall promptly notify the Holders of such ineligibility and use its commercially reasonable efforts to file a shelf registration on an appropriate form as promptly as practicable to replace the shelf registration statement on Form S-3 and have such replacement Resale Shelf Registration Statement declared effective as promptly as practicable and to cause such replacement Resale Shelf Registration Statement to remain effective, and to be supplemented and amended to the extent necessary to ensure that such Resale Shelf Registration Statement is available or, if not available, that another Resale Shelf Registration Statement is available, for the resale of all the Registrable Securities held by the Holders until all such Registrable Securities have ceased to be Registrable Securities; provided, however, that at any time the Company once again becomes eligible to use Form S-3, the Company shall cause such replacement Resale Shelf Registration Statement to be amended, or shall file a new replacement Resale Shelf Registration Statement, such that the Resale Shelf Registration Statement is once again on Form S-3.

2.3.4 SEC Cutback. Notwithstanding the registration obligations set forth in this Section 2.3, in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the Holders thereof and use its commercially reasonable efforts to file amendments to the Resale Shelf Registration Statement as required by the Commission and/or (ii) withdraw the Resale Shelf Registration Statement and file a new registration statement (a “New Registration Statement”) on Form S-3, or if Form S-3 is not then available to the Company for such registration statement, on such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall use its commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with any publicly -available written or oral guidance, comments, requirements or requests of the Commission staff (the “SEC Guidance”). Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities), unless otherwise directed in writing by a Holder as to further limit its Registrable Securities to be included on the Registration Statement, the number of Registrable Securities to be registered on such Registration Statement will be reduced on a Pro Rata basis based on the total number of Registrable Securities held by the Holders, subject to a determination by the Commission that certain Holders must be reduced first based on the number of Registrable Securities held by such Holders. In the event the Company amends the Resale Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Resale Shelf Registration Statement, as amended, or the New Registration Statement.

2.3.5 Underwritten Shelf Takedown. At any time and from time to time after a Resale Shelf Registration Statement has been declared effective by the Commission, the Holders may request to sell all or any portion of the Registrable Securities in an underwritten offering that is registered pursuant to the Resale Shelf Registration Statement (each, an “Underwritten Shelf Takedown”); provided, however, that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include securities with a total offering price (including piggyback securities and before deduction of underwriting discounts or commissions) reasonably expected to exceed, in the aggregate, $25,000,000. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company at least ten (10) days prior to the public announcement of such Underwritten Shelf Takedown, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such Underwritten Shelf Takedown. Except in the case of a requested Underwritten Shelf Takedown in the form of a Block Trade, following receipt of a request for an Underwritten Shelf Takedown, the Company shall promptly notify the other Holders of the request and of their right to participate in the Underwritten Shelf Takedown, which shall specify the anticipated public announcement date. The Company shall include in any Underwritten Shelf Takedown the securities requested to be included by any Holder (each a “Takedown Requesting Holder”) at least 48 hours prior to the anticipated public announcement date of such Underwritten Shelf Takedown set forth in the Company notice pursuant to written contractual piggyback registration rights of such Holder (including those set forth herein). All such Holders proposing to distribute their Registrable Securities through an Underwritten Shelf Takedown under this subsection 2.3.5 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the majority-in-interest of the Takedown Requesting Holders initiating the Underwritten Shelf Takedown.

2.3.6 Reduction of Underwritten Shelf Takedown. If the managing Underwriter(s) in an Underwritten Shelf Takedown, in good faith, advise(s) the Company and the Takedown Requesting Holders in writing that the dollar amount or number of Registrable Securities that the Takedown Requesting Holders desire to sell, taken together with all other shares of the Common Stock or other equity securities that the Company desires to sell, exceeds the Maximum Number of Securities, then the Company shall include in such Underwritten Shelf Takedown, as follows: (i) first, the Registrable Securities of the Takedown Requesting Holders, on a Pro Rata basis, that can be sold without exceeding the Maximum Number of Securities; and (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities.

2.3.7 Registrations effected pursuant to this Section 2.3 shall not be counted as Demand Registrations effected pursuant to Section 2.1. Under no circumstances shall the Company be obligated to effect more than an aggregate of four (4) Underwritten Shelf Takedowns in any 12-month period.

2.3.8 Block Trades. If the Company shall receive a request from a Holder or Holders of Registrable Securities with an estimated market value of at least $25,000,000 that the Company effect the sale of al or any portion of such Registrable Securities in an Underwritten Shelf Takedown in the form of a Block Trade, then the Company shall, as expeditiously as possible, cooperate and effect the offering in such Block Trade of the Registrable Securities for which such requesting Holder has requested such offering, without giving any effect to any required notice periods or delivery of notices to any other Holders. Any offering conducted as a Block Trade will not count as an Underwritten Shelf Takedown for the purposes of Section 2.3.7.

Section 2.4. Restrictions on Registration Rights. Notwithstanding anything to the contrary contained herein, the Company shall not be obligated to (but may, at its sole option) file a Registration Statement pursuant to a Demand Registration request made under Section 2.1 during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to subsection 2.1.1 and that the Company continues to actively employ, in good faith, commercially reasonable efforts to cause the applicable Registration Statement to become effective.

ARTICLE III
COMPANY PROCEDURES

3.1.4 prior to any public offering of Registrable Securities, use its commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “Blue Sky” laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

3.1.5 cause all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed;

3.1.11 permit a representative of the Holders, the Underwriter(s), if any, and any attorney or accountant retained by such Holders or Underwriter(s) to participate, at each such person’s own expense (except as otherwise set forth herein), in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter(s), attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriter(s) enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

3.1.12 obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter(s) may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders and such managing Underwriter;

3.1.13 on the date the Registrable Securities are delivered for sale pursuant to such Registration, if requested by the Underwriter(s), if any, obtain an opinion and negative assurance letter, dated such date, of counsel representing the Company for the purposes of such Registration addressed to the Underwriter(s) covering such legal matters with respect to the Registration in respect of which such opinion and negative assurance letter are being given as are customarily included in such opinions and negative assurance letters;

It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders.

Section 3.3. Requirements for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements.

Section 3.4. Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until he, she or it has received copies of a supplemented or amended Prospectus correcting the Misstatement or until he, she, or it is advised in writing by the Company that the use of the Prospectus may be resumed, provided that the Company hereby covenants to prepare and file any required supplement or amendment correcting any Misstatement promptly after the time of such notice and, if necessary, to request the immediate effectiveness thereof. If the filing, initial effectiveness or continued use of a Registration Statement or Prospectus included in any Registration Statement at any time (a) would require the Company to make an Adverse Disclosure, (b) would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment of the Board, would be materially detrimental to the Company, the Company shall have the right to defer the filing, initial effectiveness or continued use of any Registration Statement pursuant to (a), (b) or (c) for a period of not more than ninety (90) days and the Company shall not defer any such filing, initial effectiveness or use of a Registration Statement pursuant to this Section 3.4 more than twice (in each case counting deferrals initiated pursuant to (a), (b) and (c) in the aggregate) in any 12-month period. In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.

Section 3.5. Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any customary legal opinions as reasonably requested. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

Section 3.6. Limitations on Registration Rights. Other than the registration rights granted to the purchasers under the Subscription Agreements to be entered into on about the date hereof with certain investors relating to the private placement of shares of Common Stock as provided for in the Business Combination Agreement, the Company shall not hereafter enter into any agreement with respect to its securities which is inconsistent with or violates the rights granted to the Holders of Registrable Securities in this Agreement and in the event of any conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

ARTICLE IV
INDEMNIFICATION AND CONTRIBUTION

Section 4.1. Indemnification

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriter(s), their officers and directors and each person who controls (within the meaning of the Securities Act) such Underwriter(s) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls (within the meaning of the Securities Act) the Company against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds actually received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriter(s), their officers, directors and each person who controls (within the meaning of the Securities Act) such Underwriter(s) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided, however, that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from al liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution (pursuant to subsection 4.1.5) to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds actually received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

4.1.6 Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in any underwriting agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.
