Each Demand Request shall (x) specify the number of Registrable Securities that the Requesting Holders intend to sell or dispose of, (y) state the intended method or methods of sale or disposition of the Registrable Securities and (z) specify the expected price range (net of underwriting discounts and commissions) acceptable to the Requesting Holders to be received for such Registrable Securities. Following receipt of a Demand Request, the Company shall:

(i) cause to be filed, as soon as practicable, but in any event within 90 calendar days of the date of delivery to the Company of the Demand Request, a Registration Statement covering such Registrable Securities which the Company has been so requested to register by the Requesting Holders and other Holders who request to the Company that their Registrable Securities be registered within 20 calendar days of the mailing of the Request Notice, providing for the registration under the Securities Act of such Registrable Securities to the extent necessary to permit the disposition of such Registrable Securities in accordance with the intended method of distribution specified in such Demand Request;

(ii) use its best efforts to have such Registration Statement declared effective by the SEC as soon as practicable thereafter; and

(iii) refrain from filing any other Registration Statements, other than pursuant to a Registration Statement on Form S-4 or S-8 (or similar or successor forms), with respect to any other securities of the Company until such date which is 120 calendar days following effectiveness of the Registration Statement filed in response to the Demand Request.

(b) Effective Registration Statement. A registration requested pursuant to this ARTICLE II shall not be deemed to have been effected (i) unless a Registration Statement with respect thereto has become effective and remained effective in compliance with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the Holders thereof set forth in such Registration Statement; (ii) if, after it has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court for any reason and has not thereafter become effective, or if the offering of Registrable Securities is not consummated for any reason, including, without limitation, if the underwriters of an underwritten public offering advise the Participating Holders that the Registrable Securities cannot be sold at a net price per share equal to or above the minimum net price identified in the Demand Request; (iii) if the conditions to closing specified in the underwriting agreement, if any, entered into in connection with such registration are not satisfied or waived; or (iv) if the amount of Registrable Securities of Requesting Holders included in the registration are cut back to fewer than 50% of the Registrable Securities originally requested to be registered unless such cut back is the result of comments received from the Securities and Exchange Commission.

(i) In the event the Requesting Holders intend to distribute the Registrable Securities covered by the Demand Request by means of an underwriting, they shall so advise the Company as part of the Demand Request and the Company shall include such information in the Request Notice. The managing underwriter for such underwriting shall be one or more reputable nationally recognized investment banks selected by Requesting Holders owning a majority of the Registrable Securities included in such Registration Statement (a Majority in Interest of the Requesting Holders) subject to the approval of the Company, which approval shall not be unreasonably withheld, delayed or conditioned. In such event, the right of any Holder to include such Holders Registrable Securities in such registration shall be conditioned upon such Holders participation in such underwriting and the inclusion of such Holders Registrable Securities in the underwriting to the extent provided in this Section 2.2(c). All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting.

(ii) Notwithstanding any other provision of this ARTICLE II, if the managing underwriter of an underwritten public offering determines and advises the Participating Holders and the Company in writing that the inclusion of all securities proposed to be included by the Company and any other holders of Company securities requesting inclusion of their securities in the underwritten public offering other than the Participating Holders would materially and adversely interfere with the successful marketing of the Registrable Securities, then the Company and the other holders of Company securities shall not be permitted to include any securities in excess of the amount, if any, of securities which the managing underwriter of such underwritten public offering shall reasonably and in good faith agree in writing to include in such public offering in addition to the amount of Registrable Securities to be registered for accounts of the Participating Holders. If the managing underwriter concludes that less than all of the Registrable Securities which the Participating Holders propose to include in the offering can be successfully sold in the offering, the managing underwriter will be obligated to include in such Registration Statement, as to each Participating Holder, only that portion of the Registrable Securities such Participating Holder has requested be registered equal to the ratio which such Participating Holders requested Registrable Securities bears to the total number of Registrable Securities requested to be included in such Registration Statement by all Participating Holders who have requested that their Registrable Securities be included in such Registration Statement; provided, however, that the number of Registrable Securities requested to be included in such offering by a Participating Holder shall not be reduced until all Registrable Securities proposed to be registered by any Participating Holder who is either a founder, officer, director or employee of the Company are first entirely eliminated from the offering.

(d) Limitations on Demand Registrations.

(i) The Company may delay making a filing of a Registration Statement or taking action in connection therewith by not more than 60 calendar days after receipt of the Demand Request if the Company provides a written certificate signed by the Chief Executive Officer and Chief Financial Officer of the Company to the Holders, prior to the time it would otherwise have been required to file such Registration Statement or take such action pursuant to this Section 2.2, stating that the Board has determined in good faith that it would be seriously detrimental to the Company and its stockholders if such Registration Statement (or an amendment thereto) were filed and such Registration Statement (or amendment) were to become effective, or remain effective for the time otherwise required for such Registration Statement to remain effective, because such action either would (A) materially adversely affect a significant financing, acquisition, disposition, merger or other material transaction, (B) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential or (C) render the Company unable to comply with requirements under the Securities Act or the Exchange Act (each, a Valid Business Reason) and that it is therefore essential to defer the filing of the Registration Statement; provided, however, that such right to delay a Demand Request shall be exercised by the Company not more than once in any 12 month period and the Company shall only have the right to delay a Demand Request so long as such Valid Business Reason exists, and during such time the Company may not file a Registration Statement for securities to be issued and sold for its own account or for that of anyone other than the Holders.

(ii) The Company shall only be obligated to effect two (2) Series B Demand Requests and two (2) Non-Series B Demand Requests pursuant to this Section 2.2 and the Holders agree not to make a Demand Request any earlier than six (6) months after the effective date of a Registration Statement relating to a previous Demand Request. If the underwriter of such registration determines that marketing factors require a limitation on the aggregate amount of securities sold on the market, the underwriter may cut back the requesting Holders pro rata, based on the number of Registrable Securities for which such Holders requested registration. Cutbacks will be made first against all shares of stock being sold which are not Registrable Securities. Once all such shares have been cut back, all shares of Registrable Securities will be cut back pro-rata based upon the total number of shares of Registrable Securities requested to be registered by each Holder.

(e) Cancellation of Registration. A Majority in Interest of the Requesting Holders shall have the right to cancel a proposed registration of Registrable Securities pursuant to this Section 2.2 when, (i) in their discretion, market conditions are so unfavorable as to be seriously detrimental to an offering pursuant to such registration or (ii) the request for cancellation is based upon material adverse information relating to the Company that is different from the information known to the Requesting Holders at the time of the Demand Request. Such cancellation of a registration shall not be counted as one of the two (2) Series B Demand Requests or Non-Series B Demand Requests, as applicable, and notwithstanding anything to the contrary in the Agreement, the Company shall be responsible for the expenses of the Participating Holders incurred in connection with the registration prior to the time of cancellation.

Section 2.3

Piggyback Registrations.

(a) Right to Include Registrable Securities. Each time after the Companys IPO that the Company proposes for any reason to register any of its Common Stock under the Securities Act, either for its own account or for the account of a stockholder or stockholders exercising demand registration rights (other than the Form S-3 Demand pursuant to Section 2.4 hereof or under a registration statement on Form S-8 or S-4) (a Proposed Registration), the Company shall promptly give written notice of such Proposed Registration to all of the Holders of Registrable Securities (which notice shall be given not less than thirty (30) calendar days prior to the expected effective date of the Companys Registration Statement) and shall offer such Holders the right to request inclusion of any of such Holders Registrable Securities in the Proposed Registration; provided, however, that the Holders shall have no right to include Registrable Securities in a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction. No registration pursuant to this Section 2.3 shall relieve the Company of its obligation to register Registrable Securities pursuant to a Demand Request, as contemplated by Section 2.2 hereof. The rights to piggyback registration may be exercised an unlimited number of occasions.

(b) Piggyback Procedure. Each Holder of Registrable Securities shall have ten (10) calendar days from the date of receipt of the Companys notice referred to in Section 2.3(a) above to deliver to the Company a written request specifying the number of Registrable Securities such Holder intends to sell and such Holders intended method of disposition. Any Holder shall have the right to withdraw such Holders request for inclusion of such Holders Registrable Securities in any Registration Statement pursuant to this Section 2.3 by giving written notice to the Company of such withdrawal. Subject to Section 2.3(c) below, the Company shall use its best efforts to include in such Registration Statement all such Registrable Securities so requested to be included therein; provided, however, that the Company may at any time withdraw or cease proceeding with any such Proposed Registration if it shall at the same time withdraw or cease proceeding with the registration of all other shares of Common Stock originally proposed to be registered.

(c) Priority for Piggyback Registration. Notwithstanding any other provision of this ARTICLE II, if the managing underwriter of an underwritten public offering determines and advises the Company and the Participating Holders in writing that the inclusion of all Registrable Securities proposed to be included by the Participating Holders of Registrable Securities in the underwritten public offering would materially and adversely interfere with the successful marketing of the Companys securities, then the Participating Holders shall not be permitted to include any Registrable Securities in excess of the amount, if any, of Registrable Securities which the managing underwriter of such underwritten public offering shall reasonably and in good faith agree in writing to include in such public offering in addition to the amount of securities to be registered for the account of the Company. In no event shall any Registrable Securities be excluded from such offering unless all other stockholders securities are excluded other than those stockholders making the demand, if any. The Company will be obligated to include in such Registration Statement, as to each Participating Holder, only that portion of the Registrable Securities such Participating Holder has requested be registered equal to the product of (i) the total number of Registrable Securities which the managing underwriter agrees to include in the public offering and (ii) the ratio which such Participating Holders requested Registrable Securities bears to the total number of Registrable Securities requested to be included in such Registration Statement by all Participating Holders who have requested that their Registrable Securities be included in such Registration Statement. It is acknowledged by the parties hereto that pursuant to the foregoing provision, the securities to be included in a registration initiated by the Company shall be allocated as set forth below (with cutbacks, if any, being made in reverse order) :

(i) first, to the Company;

(ii) second, to the Participating Holders who are Purchasers;

(iii) third, pari passu to the Participating Holders other than the Purchasers; and

(iv) fourth, to any others requesting registration of securities of the Company.

Notwithstanding the foregoing, in no event shall the amount of securities of the Participating Holders included in the offering be reduced below 50% of the total amount of securities included in the offering, unless such offering is the IPO, in which case the Participating Holders may be excluded below this amount if the underwriters make the determination described above and no other stockholders securities are included in such offering. If as a result of the provisions of this Section 2.3(c), any Holder shall not be entitled to include more than 50% of its Registrable Securities in a registration that such Holder has requested to be so included, such Holder may withdraw such Holders request to include Registrable Securities in such Registration Statement.

(d) Underwritten Offering. In the event the Proposed Registration by the Company is, in whole or in part, an underwritten public offering of securities of the Company, any notice from the Company to the Holders under this Section 2.3 shall offer the Holders the right to include any Registrable Securities covered by the Proposed Registration in the underwriting on the same terms and conditions as the shares, if any, otherwise being sold through underwriters under such registration. The managing underwriter for any Proposed Registration that involves an underwritten public offering shall be one or more reputable nationally recognized investment banks selected by the Company.

Section 2.4

Form S-3 Registration. Any Holder (an Initiating Form S-3 Holder) may request at any time following the Companys IPO that the Company file a Registration Statement under the Securities Act on Form S-3 (or similar or successor form) covering the sale or other distribution of all or any portion of the Registrable Securities held by such Initiating Form S-3 Holder pursuant to Rule 415 under the Securities Act (Form S-3 Demand) if (i) the reasonably anticipated aggregate gross proceeds from the sale of such Registrable Securities would equal or exceed $1,000,000, (ii) the Company is a registrant qualified to use Form S-3 (or any similar or successor form) to register such Registrable Securities and (iii) the plan of distribution of the Registrable Securities is other than pursuant to an underwritten public offering. If such conditions are met, the Company shall use its best efforts to register under the Securities Act on Form S-3 (or any similar or successor form) at the earliest practicable date, for sale in accordance with the method of disposition specified in the Form S-3 Demand, the number of Registrable Securities specified in such Form S-3 Demand. In connection with a Form S-3 Demand, the Company agrees to include in the prospectus included in any Registration Statement on Form S-3, such material describing the Company and intended to facilitate the sale of securities being so registered as is reasonably requested for inclusion therein by the Initiating Form S-3 Holders, whether or not the rules applicable to preparation of Form S-3 require the inclusion of such information. Notwithstanding the foregoing, the Company may delay making a filing of a Registration Statement or taking action in connection therewith by not more than 60 calendar days after receipt of the Form S-3 Demand Request if the Company provides a written certificate signed by the Chief Executive Officer and Chief Financial Officer of the Company to the Initiating Form S-3 Holders, prior to the time it would otherwise have been required to file such Registration Statement or take such action pursuant to this Section 2.4, stating that the Board has determined in good faith that a Valid Business Reason exists to defer the filing of the Registration Statement; provided, however, that such right to delay a Form S-3 Demand Request shall be exercised by the Company not more than once in any 12 month period and the Company shall only have the right to delay a Form S-3 Demand Request so long as such Valid Business Reason exists, and during such time, the Company may not file a Registration Statement for securities to be issued and sold for its own account or for that of anyone other than the Holders. Form S-3 Demands will not be deemed to be Demand Requests as described in Section 2.2 hereof and Holders shall have the right to request an unlimited number of Form S-3 Demands.

Section 2.5

Holdback Agreements.

(a) Restrictions on Public Sale by Holders. Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the Companys IPO and ending on the date specified by the Company and the managing underwriter (such period not to exceed 180 calendar days) (the Lock-Up Period) (i) lend, offer, pledge, 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, or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise; provided, however, that if any other holder of securities of the Company is or becomes subject to a shorter Lock-Up Period or receives more advantageous terms relating to the Lock-Up Period under any lock-up agreement (including but not limited to as a result of any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters), then the Lock-Up Period shall be such shorter period and also on such more advantageous terms. The provisions of this Section 2.5(a) shall not apply to the sale of any shares to an underwriter pursuant to an underwritten offering and shall only apply if all of the Companys directors, officers and stockholders owning five percent or more of the Companys fully diluted voting stock have signed lock-up agreements with the managing underwriter. Any such lock-up agreements signed by the Holders shall contain reasonable and customary exceptions, including, without limitation, the right of a Holder to make transfers to certain Affiliates and transfers related to shares of Common Stock owned by Holders as a result of open market purchases made following the closing of the IPO.

(b) Restrictions on Public Sale by the Company. The Company agrees not to effect any public sale or distribution of any securities for its own account (except pursuant to registrations on Form S-4 or S-8 or any similar or successor form) during the Lock-Up Period, to the extent reasonably requested by the managing underwriter (except for securities being sold by the Company for its own account under such Registration Statement).

Section 2.8

Indemnification.

(a) Indemnification by the Company. In the event any Registrable Securities are included in a Registration Statement, the Company will indemnify and hold harmless to the fullest extent permitted by law each Holder, each of its directors, officers, employees, advisors, agents, stockholders, members, general partners and limited partners (and the directors, officers, employees, advisors, agents, stockholders, members, general partners and limited partners thereof), their respective Affiliates and each Person who controls (within the meaning of the Securities Act or the Exchange Act) any of such Persons, and each underwriter and each Person who controls (within the meaning of the Securities Act or the Exchange Act) any underwriter (collectively, Company Indemnified Parties) from and against any and all losses, claims, damages, expenses (including, without limitation, reasonable costs of investigation and fees, disbursements and other charges of counsel, any amounts paid in settlement effected with the Companys consent, which consent shall not be unreasonably withheld or delayed, and any costs incurred in enforcing the Companys indemnification obligations hereunder) or other liabilities (collectively, Losses) to which any such Company Indemnified Party may become subject under the Securities Act, the Exchange Act, any other federal, state or foreign law or any rule or regulation promulgated thereunder, or under any common law or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) are resulting from or arising out of or based upon (i) any untrue, or alleged untrue, statement of a material fact contained in any Registration Statement, including any prospectus or preliminary prospectus contained therein or any amendments or supplements thereto, or any document incorporated by reference in any of the foregoing or resulting from or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made), not misleading or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other federal law, any state or foreign securities law, or any rule or regulation promulgated under any of the foregoing laws, relating to the offer or sale of the Registrable Securities, and in any such case the Company will promptly reimburse each such Company Indemnified Party for any legal and any other Losses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability, action or investigation or proceeding (collectively, a Claim). Such indemnity obligation shall remain in full force and effect regardless of any investigation made by or on behalf of the Company Indemnified Parties and shall survive the transfer of Registrable Securities by such Company Indemnified Parties.

(b) Indemnification by Holders. In connection with any proposed registration in which a Holder is participating pursuant to this Agreement, each such Holder shall furnish to the Company in writing such information with respect to such Holder as the Company may reasonably request or as may be required by law for use in connection with any Registration Statement or prospectus or preliminary prospectus to be used in connection with such registration and each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, any underwriter retained by the Company, any other Holder selling securities in such Registration Statement and their respective directors, officers, partners, employees, advisors, agents, stockholders, members, general partners and limited partners, and their respective Affiliates, and each Person who controls (within the meaning of the Securities Act or the Exchange Act) any of such Persons (collectively, Holder Indemnified Parties) to the same extent as the foregoing indemnity from the Company to the Holders as set forth in Section 2.8(a) (subject to the exceptions set forth in the foregoing indemnity, the proviso to this sentence and applicable law), but only with respect to any such information furnished in writing by such Holder expressly for use in such Registration Statement; provided, however, that the liability of any Holder under this Section 2.8(b) shall be limited to the amount of the net proceeds received by such Holder in the offering giving rise to such liability. Such indemnity obligation shall remain in full force and effect regardless of any investigation made by or on behalf of the Holder Indemnified Parties and shall survive the transfer of Registrable Securities by such Holder.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder (the Indemnified Party) agrees to give prompt written notice to the indemnifying party (the Indemnifying Party) after the receipt by the Indemnified Party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to this Agreement; provided, however, that, the failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party hereunder unless and to the extent such Indemnifying Party is materially prejudiced by such failure. If notice of commencement of any such action is given to the Indemnifying Party as above provided, the Indemnifying Party shall be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense, with counsel chosen by it and reasonably satisfactory to such Indemnified Party. The Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be paid by the Indemnified Party unless (i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party fails to assume the defense of such action with counsel satisfactory to the Indemnified Party in its reasonable judgment or (iii) the Indemnified Party reasonably believes that the joint representation of the Indemnified Party and any other party in such proceeding (including but not limited to the Indemnifying Party) would be inappropriate due to actual or potential differing interests between such Indemnified Party and the other party represented by the same counsel. In the case of clause (ii) above and (iii) above, the Indemnifying Party shall not have the right to assume the defense of such action on behalf of such Indemnified Party. No Indemnifying Party shall be liable for any settlement entered into without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the written consent of the Indemnified Party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the Indemnified Party from all liability arising out of such action or claim and (B) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any Indemnified Party. The rights afforded to any Indemnified Party hereunder shall be in addition to any rights that such Indemnified Party may have at common law, by separate agreement or otherwise.

(d) Contribution. If the indemnification provided for in this Section 2.8 from the Indemnifying Party is unavailable or insufficient to hold harmless an Indemnified Party in respect of any Losses 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 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 faults 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 Partys and Indemnified Partys relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 2.8(d) shall be limited to the amount of the net proceeds received by such Holder in the 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 Section 2.8(a), Section 2.8(b) and Section 2.8(c), 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 Section 2.8(d) 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 the immediately preceding paragraph. 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 Section 2.8(d) from any Person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of the Company and Holders under this ARTICLE II shall survive the completion of any offering of Registrable Securities pursuant to a registration statement under this ARTICLE II, and shall survive the termination of this Agreement.

Section 2.9

Rule 144 and Rule 144A; Other Exemptions. With a view to making available to the Holders the benefits of Rule 144 and Rule 144A promulgated under the Securities Act and other rules and regulations of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration, the Company covenants that it will (i) file in a timely manner all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder and (ii) take such further action as each Holder may reasonably request (including, but not limited to, providing any information necessary to comply with Rule 144 and Rule 144A, if available with respect to resales of the Registrable Securities under the Securities Act), at all times from and after the date which is 90 calendar days following the Companys IPO, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (x) Rule 144 and Rule 144A (if available with respect to resales of the Registrable Securities) under the Securities Act, as such rules may be amended from time to time or (y) any other rules or regulations now existing or hereafter adopted by the SEC. Upon the written request of a Holder, the Company shall deliver to the Holder a written statement as to whether it has complied with such requirements. The Company will use its best efforts to assist a Holder in facilitating private sales of Registrable Securities by, among other things, providing officers certificates and other customary closing documents reasonably requested by a Holder.

Section 2.10

Certain Limitations On Registration Rights. No Holder may participate in any Registration Statement hereunder involving an underwritten public offering unless such Holder completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, and other documents reasonably required under the terms of the underwriting arrangements made in connection with such Registration Statement and agrees to sell such Holders Registrable Securities on the basis provided in any underwriting agreement approved by the Holder or Holders entitled hereunder to approve such arrangements; provided, however, that no such Holder shall be required to make any representations or warranties to the Company or the underwriters in connection with any such registration other than representations and warranties as to (i) such Holders ownership of its Registrable Securities to be sold or transferred, (ii) such Holders power and authority to effect such transfer and (iii) such matters pertaining to compliance with securities laws as may be reasonably requested. Such Holders of Registrable Securities to be sold by such underwriters may, at their option, require that any or all of the representations and warranties by, and the other agreements on the part of the Company to and for the benefit of such underwriters, shall also be made to and for the benefit of such Holders and that any or all of the conditions precedent to the obligations of the underwriters under the underwriting agreement be conditions precedent to the obligations of the Holders.

Section 2.11

Limitations on Subsequent Registration Rights. Except as set forth on Schedule 2.11 hereto, the Company represents and warrants that it has not granted registration rights prior to the date hereof and agrees that from and after the date of this Agreement, it shall not, without the prior written consent of the Holders of at least 66-2/3% of the Registrable Securities then outstanding, enter into any agreement (or amendment or waiver of the provisions of any agreement) with any holder or prospective holder of any securities of the Company that would grant such holder registration rights that are more favorable, pari passu or senior to those granted to the Preferred Stockholders hereunder.

Section 2.12

Section 3.3

Procedure. The Company will give each Rights Holder at least 20 calendar days prior written notice of the Companys intention to issue New Securities (the New Securities Notice), describing the type and amount of New Securities to be issued and the price and the general terms and conditions upon which the Company proposes to issue such New Securities. Each Rights Holder may purchase any or all of such Rights Holders Pro Rata Share of such New Securities, by delivering to the Company, within 15 calendar days after the date of mailing of any such New Securities Notice by the Company, a written notice specifying such number of New Securities which such Rights Holder desires to purchase (which may be all or any part of such New Securities), for the price and upon the general terms and conditions specified in the New Securities Notice. If any Rights Holder fails to notify the Company in writing within such 15 calendar day period of its election to purchase any or all of such Rights Holders Pro Rata Share of an offering of New Securities (a Nonpurchasing Holder), then such Nonpurchasing Holder will forfeit the right hereunder to purchase that part of such Rights Holders Pro Rata Share of such New Securities that such Rights Holder did not agree to purchase. If any Rights Holder fails to elect to purchase the full amount of such Rights Holders Pro Rata Share of the New Securities, the Company shall give notice of such failure to the Rights Holders who did so elect (the Purchasing Holders). Such notice may be made by telephone if confirmed in writing within two (2) calendar days. A Purchasing Holder shall have five (5) calendar days from the date such notice was given to such Purchasing Holder to notify the Company in writing of its election to purchase its pro rata portion of the total number of New Securities not subscribed for by the Nonpurchasing Holders.

Each Purchasing Holders pro rata portion thereof shall be equal to the sum of the number of shares of Common Stock held by such Purchasing Holder plus the number of shares of Common Stock into which all shares of Preferred Stock held by such Purchasing Holder are convertible on the date of the New Securities Notice, as a percentage of the total number of shares of Common Stock held by all Purchasing Holders plus the number of shares of Common Stock into which all shares of Preferred Stock held by all such Purchasing Holders are convertible on the date of the New Securities Notice.

Section 3.4

Failure To Exercise. In the event that the Rights Holders fail to exercise in full the purchase right within such 15 calendar day period, then the Company will have 60 calendar days thereafter to sell the New Securities with respect to which the Rights Holders rights hereunder were not exercised, at a price and upon terms and conditions not more favorable to the purchasers thereof than specified in the New Securities Notice to the Rights Holders. In the event that the Company has not issued and sold the New Securities within such 60 calendar day period, then the Company shall not thereafter issue or sell any New Securities without again first offering such New Securities to the Rights Holders pursuant to this ARTICLE III.

The Company will pay and cause any Subsidiary to pay, when due, or in conformity with customary trade terms, all lease obligations, all trade debt, and all other indebtedness incident to the operations of the Company or any Subsidiary, except such as are being contested in good faith and by proper proceedings if the Company or Subsidiary concerned has set aside on its books sufficient reserves, if any, with respect thereto.

Section 4.9

Section 4.10

Activities of Subsidiaries. The Company will not, and will not permit any Subsidiary to, organize or acquire any entity, or acquire any equity interest in any entity, unless such entity is a Subsidiary that is (i) wholly-owned (directly or indirectly) by the company or one of its Subsidiaries or (ii) at least eighty percent (80%) owned by the Company or one of its Subsidiaries and the other holders of such Subsidiary are either universities, inventors or pharmaceutical partners that receive their equity stake in such Subsidiary as consideration for their contribution of assets to such Subsidiary. The Company will not permit any Subsidiary to consolidate or merge, or sell or transfer all or substantially all of its assets, except that any Subsidiary may (i) consolidate or merge into or with or sell or transfer assets to any other wholly-owned Subsidiary of the Company, or (ii) merge into or sell or transfer assets to the Company. The Company will not permit any Subsidiary to purchase or set aside any sums for the purchase of, or pay any dividend or make any distribution on, any shares of its stock, except for dividends or other distributions payable to the Company or another wholly-owned Subsidiary.

Section 4.11

If at any time either the Company or any Subsidiary becomes a PFIC, such entity will, at its sole expense, provide the Purchasers with such information and take such other actions as may be necessary to permit the Purchasers to make a timely election under Section 1295 of the Code to treat the Company as a qualified electing fund. Further, at the request of any Purchaser, the Company will, at the Companys expense, timely provide such Purchaser with any information that such Purchaser reasonably requests for purposes of completing United State federal, state or local income tax returns, including, without limitation, with respect to the status as a CFC of the Company or any Subsidiary.

Preferred Stock Covenant. The Company agrees to treat the Series B Preferred Stock as stock that participates in the corporate growth of the Company to a significant extent within the meaning of Treasury Regulation Section 1.305-5(a), and hence will not treat the Series B Preferred Stock as preferred stock for purposes of the Code.

Section 5.13

Construction. This Agreement has been freely and fairly negotiated among the parties. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring any party because of the authorship of any provision of this Agreement.

The words include, includes, and including will be deemed to be followed by without limitation.

The words this Agreement, herein, hereof, hereby, hereunder, and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties intend that each representation, warranty, and covenant contained herein will have independent significance. If any party has breached any covenant contained herein in any respect, the fact that there exists another covenant relating to the same subject matter (regardless of the relative levels of specificity) which the party has not breached will not detract from or mitigate the fact that the party is in breach of the first covenant.

Section 5.14

Attorneys Fees. If any dispute among any parties arises in connection with this Agreement, the prevailing party in the resolution of such dispute in any action or proceeding will be entitled to an order awarding full recovery of reasonable attorneys fees and expenses, costs and expenses (including experts fees and expenses and the costs of enforcing this Section 5.14) incurred in connection therewith, including court costs, from the non-prevailing party.

Section 5.16

Aggregation of Stock. All shares of Common Stock owned or acquired by any Preferred Stockholder or its Affiliated entities or persons (assuming full conversion, exchange and exercise of all convertible, exchangeable and exercisable securities into Common Stock) shall be aggregated together for the purpose of determining the availability of any right under this Agreement.

Section 5.17
