ARTICLE II

REGISTRATION RIGHTS

Section 2.1 Demand Registration.

(a) Subject to the conditions of this Section 2.1, if the Company shall receive, at any time after the earlier of (i) three (3) years from the Closing and (ii) six (6) months following the closing of the Initial Offering, a written request from a Preferred Holder or Preferred Holders holding thirty percent (30%) or more of the Registrable Securities then outstanding (the “Initiating Holder(s)”), that the Company file a registration statement under the Act covering the registration of (a) with respect to any written request prior to the Initial Offering, at least twenty percent (20%) of the Registrable Securities then outstanding (or a lesser percentage provided that such registration under this Section 2.1 shall have an aggregate offering price, net of underwriting discounts and commissions, of $10,000,000 or more) and (b) with respect to any written request following the Initial Offering, any amount of the Registrable Securities then outstanding, then the Company shall:

(i)

within ten (10) days of the receipt thereof, give written notice of such request to all other Preferred Holders;

(ii)

subject to the limitations of this Section 2.1, use all reasonable efforts, as soon as practicable, and in any event within ninety (90) days of the receipt of such request, to file a registration statement under the Act covering all Registrable Securities which the Initiating Holder(s) request to be registered, together with all or any portion of Registrable Securities of any other Preferred Holders joining in such request as are specified in a written request delivered to the Company in accordance with Section 6.6 and received by the Company within twenty (20) days after the mailing of the Company’s notice pursuant to Section 2.1(a); and

(iii)

use its reasonable efforts to cause such registration statement to be declared effective by the SEC as soon as practicable.

Each such request by a Preferred Holder (other than the Initiating Holder(s)) shall specify the number of Registrable Securities proposed to be registered and the intended method of disposition thereof. The failure of any Preferred Holder (other than the Initiating Holder(s)) to respond within such twenty (20) day period referred to in clause (ii) above shall be deemed to be a waiver of such Preferred Holder’s rights under this Section 2.1 with respect to such registration, provided that any such Preferred Holder may waive its or his rights under this Section 2.1 prior to the expiration of such twenty (20) day period by giving written notice to the Company, with a copy to the Initiating Holder(s). The Preferred Holders shall be limited to a maximum of two (2) demand registrations pursuant to this Section 2.1; provided, however, that Xxxxx Brothers Investments (“BBI”) shall maintain a right to demand one (1) registration pursuant to this Section 2.1 in the event that the two (2) demand registrations are made by Preferred Holders other than BBI and BBI does not participate in such registrations. The Company shall not be required to effect more than one (1) registration in any twelve (12) month period. A registration will not count toward the Preferred Holders’ limit of two (2) demand registrations pursuant to this Section 2.1 if (Y) less than all Registrable Securities requested to be registered by the Preferred Holders are registered (except for Registrable Securities not included in the registration as a result of an Underwriter Carveback (as defined below)), or (Z) the registration is withdrawn at the request of the Preferred Holders when the Preferred Holders have

learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Preferred Holders at the time of their registration request and have withdrawn the request with reasonable promptness following disclosure by the Company or a third party of such material adverse change.

(b) If the Initiating Holder(s) intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2.1 and the Company shall include such information in the written notice referred to in Section 2.1(a)(i). The underwriter will be selected by the Initiating Holder(s), subject only to the reasonable approval of the Company. In such event, the right of any Preferred Holder to include its or his Registrable Securities in such demand registration shall be conditioned upon such Preferred Holder’s participation in such underwriting and the inclusion of such Preferred Holder’s Registrable Securities in the underwriting to the extent provided herein. All Preferred Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided herein) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Section 2.1, if the underwriter advises the Initiating Holder(s) and the Company in writing that marketing factors require a limitation of the number of securities underwritten (“Underwriter Carvebacks”), then the Company shall so advise all Preferred Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be allocated among all Preferred Holders of Registrable Securities, including the Initiating Holders, in proportion (as nearly as practicable) to the number of Registrable Securities of the Company owned by each Preferred Holder, except that no Registrable Securities of a Preferred Holder shall be excluded unless and until all securities that are not Registrable Securities are first excluded from the underwriting. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares.

(i)

in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such demand registration, unless the Company is already subject to service in such jurisdiction and except as may be required under the Act;

(ii)

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 eighty (180) days following the effective date of, a Company-initiated registration subject to Section 2.2 below, provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective;

(iii)

if the Initiating Holder(s) propose to dispose of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.3 below; or

(iv)

if the Company shall furnish to the Initiating Holder(s) a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board of Directors stating that in the good faith judgment of the Board of Directors, it would be materially detrimental to the Company and its stockholders for such registration statement to be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holder(s), provided that such right to delay a request shall be exercised by the Company not more than once in any twelve (12) month period and provided further that the Company shall not register any securities for the account of itself or any other stockholder during such ninety (90) day period other than 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, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered.

Section 2.2 Company Registration.

(a) If (but without any obligation to do so) the Company proposes to register (whether for its own account or otherwise) any of its stock or other securities under the Act in connection with the public offering of such securities (other than (i) a registration relating solely to the sale of securities to participants in a Company stock plan, (ii) a registration relating to a corporate reorganization or other transaction on Form S-4 or under Rule 145 of the Act, (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, (iv) a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered, or (v) a registration pursuant to Section 2.1), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 6.6, the Company shall, subject to the provisions of Section 2.2(c), use all reasonable efforts to cause to be registered under the Act all of the Registrable Securities that each such Holder has requested to be registered.

(b) 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 has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company in accordance with Section 2.6 hereof.

(c) In connection with any offering involving an underwriting of shares of the Company’s capital stock, the Company shall not be required under this Section 2.2 to include any of the Preferred Holders’ Registrable Securities or the ARIAD Holder’s Registrable Securities or any of the Common Holder’s Common Stock in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it and enter into an underwriting agreement in customary form with an underwriter or underwriters selected by the Company, and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by Holders to be included in such offering exceeds the amount of securities sold other than by the Company that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, that the underwriters determine in their reasonable discretion will not jeopardize the success of the offering; provided, however, that no such reduction shall reduce the amount of Registrable Securities of the selling Holders included in the offering below twenty-five percent (25%) of the total amount of securities included in such offering, unless such offering is the Initial Offering and such registration does not include shares of any other selling stockholders, in which event any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding clause. In no event shall any Registrable Securities be excluded from such offering unless all other stockholders’ securities have been first excluded, including all of the Common Stock owned by the Common Holders proposed to be included in the registration. In the event that the underwriters determine that less than all of the Registrable Securities or Common Stock requested to be registered can be included in such offering, then the Registrable Securities and shares of Common Stock that are included in such offering shall be apportioned pro rata among the Selling Preferred Holders and the ARIAD Holder based on the number of Registrable Securities held by all Selling Preferred Holders and the ARIAD Holder or in such other proportions as shall mutually be agreed to by all such Parties. For purposes of apportionment, for any selling stockholder which is a Preferred Holder of Registrable Securities and which is an investment fund, partnership, limited liability company or corporation, the partners, members, retired partners, retired members, stockholders and Affiliates of such Preferred Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “Selling Preferred Holder”, and any pro-rata reduction with respect to such “Selling Preferred Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Selling Preferred Holder,” as defined in this sentence.

Section 2.3 Form S-3 Registration.

(a) Subject to the conditions of this Section 2.3, if the Company shall receive a written request from a Preferred Holder or Preferred Holders or ARIAD Holder (the “S-3 Initiating Holder(s)”), that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by the S-3 Initiating Holder(s), then the Company shall:

(i)

promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and

(ii)

as soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such S-3 Initiating Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holders joining in such request as are specified in a written request given within twenty (20) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification, or compliance, pursuant to this Section 2.3: (A) if Form S-3 is not available for such offering by the Preferred Holders or ARIAD Holder; (B) if such Holders propose to sell Registrable Securities and Common Stock at an aggregate price to the public of less than $3,000,000 (net of discounts and commissions); (C) if the Company shall furnish to such Holders a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board stating that in the good faith judgment of the Board of Directors, it would be materially detrimental to the Company and its stockholders for such Form S-3 registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Preferred Holders or ARIAD Holder under this Section 2.3, provided, that, that the Company shall not utilize this right more than once in any twelve (12) month period and provided further that the Company shall not register any securities for the account of itself or any other stockholder during such ninety (90) day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered); (D) if the Company has, within the twelve (12) month period preceding the date of such request, already effected two (2) or more registrations on Form S-3 for the Preferred Holders or ARIAD Holder pursuant to this Section 2.3; (E) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification, or compliance, unless the Company is

10.

already subject to service in such jurisdiction and except as may be required under the Act; or (F) during the period ending ninety (90) days after the effective date of a registration statement subject to Section 2.2.

(b) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the S-3 Initiating Holder(s) but in any event not later than ninety (90) days after it receives the request. Registrations effected pursuant to this Section 2.3 shall not be counted as demands for registration or registrations effected pursuant to Sections 2.1 or 2.2, respectively.

(c) If the S-3 Initiating Holder(s) intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their request made pursuant to this Section 2.3 and the Company shall include such information in the written notice referred to in Section 2.3(a)(i). The provisions of Section 2.1(b) shall be applicable to such request (with the substitution of Section 2.3 for references to Section 2.1), provided, however, in no event shall any Registrable Securities be excluded from such offering unless all other stockholders’ securities have been first excluded, including all of the Common Stock owned by the Common Holders proposed to be included in the registration.

(b) The Company shall bear and pay all expenses incurred in connection with any registration, filing or qualification of Registrable Securities with respect to the registrations pursuant to Sections 2.2 and 2.3 hereof for each Preferred Holder and ARIAD Holder (which right may be assigned as provided in Section 2.10 hereof) and each Common Holder, including (without limitation) all registration, filing, and qualification fees, printers and reasonable accounting fees relating or apportionable thereto and the reasonable fees and expenses, not to exceed an aggregate of $50,000, of one (1) counsel for the selling Holders selected by the Preferred Holders and ARIAD Holder holding a majority of the Registrable Securities to be registered, but excluding underwriting discounts and commissions relating to Registrable Securities.

(a) To the extent permitted by law, the Company will indemnify and hold harmless each selling Holder, their respective partners, members, officers, directors, and stockholders, legal counsel and accountants for each selling Holder, any underwriter (as defined in the Act) for such selling Holder and each person, if any, who controls such selling Holder or underwriter within the meaning of the Act or the 1934 Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Act, the 1934 Act, any other federal securities laws or any state securities laws, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions, or violations (collectively, a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such Registration Statement, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Act, the Exchange Act, any state securities laws or any rule or regulation promulgated under the Act, the Exchange Act, or any state securities laws; and the Company will pay to each such selling Holder, underwriter, controlling person or other aforementioned person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 2.8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter, controlling person or other aforementioned person; provided further, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Holder or underwriter, or any person controlling such Holder or underwriter, from whom the person asserting any such losses, claims, damages, or liabilities purchased shares in the offering, if a copy of the prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Holder or underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the shares to such person, and if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, or liability.

(b) To the extent permitted by law, each Selling Holder will severally and not jointly indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the Registration Statement, each person, if any, who controls the Company within the meaning of the Act, legal counsel and accountants for the Company, each underwriter, each other Holder selling securities in such Registration Statement and each partner, member, director, officer, or controlling person of each such underwriter, other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Act, the Exchange Act, any other federal securities laws or any state securities laws, insofar as such losses, claims, damages, or liabilities (or actions in respect

14.

thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay any person intended to be indemnified pursuant to this Section 2.8(b), for any reasonable legal or other expenses reasonably incurred by such person in connection with investigating or defending any such loss, claim, damage, liability, or action as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 2.8(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Selling Holder (which consent shall not be unreasonably withheld), provided that in no event shall any indemnity under this Section 2.8(b) exceed the net proceeds from the offering received by such Selling Holder, except in the case of fraud or willful misconduct by such Selling Holder.

(c) Promptly after receipt by an indemnified party under this Section 2.8 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.8, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.8, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.8.

(d) In order to provide for just and equitable contribution to joint liability under the Act in any case in which either (i) any Holder exercising rights under this Agreement, or any controlling person of any such Holder, makes a claim for indemnification pursuant to this Section 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 2.8 provides for indemnification in such case, or (ii) contribution under the Act may be required on the part of any such Selling Holder or any such controlling person in circumstances for which indemnification is provided under this Section 2.8, then, and in each such case, the Company, such will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be

15.

determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided however, that, in any such case, (i) no such Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement, and (ii) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation; provided further, that in no event shall a Holder’s liability pursuant to this Section 2.8(d), when combined with the amounts paid or payable by such holder pursuant to Section 2.8(b), exceed the proceeds from the offering (net of any underwriting discounts or commissions) received by such Holder, except in the case of fraud or willful misconduct by such Holder.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the 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.

(f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations of the Company, the Holders under this Section 2.8 shall survive the completion of any offering of Registrable Securities or Common Stock in a Registration Statement under this Article II, and shall survive the termination of this Agreement.

Section 2.9 Reports under 1934 Act. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to:

(a) make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the Initial Offering;

(b) take such action, including the voluntary registration of its Common Stock under Section 12 of the 1934 Act, as is reasonably necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities and Common Stock such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the offering of its securities to the general public is declared effective;

(c) file with the SEC in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act; and

(d) furnish to any Holder, so long as the Holder owns any Registrable Securities or Common Stock forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days following the effective date of the first registration statement filed by the Company), the

16.

Act, and the 1934 Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration or pursuant to such form.

Section 2.10 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities or Common Stock pursuant to this Article II may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of all or some of such securities that (i) is a subsidiary, Affiliate, parent, partner, member, limited partner, retired partner, retired member or stockholder of a Holder; (ii) is a Holder’s Immediate Family Member or trust for the benefit of an individual Holder or such Holder’s Immediate Family Member, respectively; (iii) is a successor by merger, reorganization or otherwise, of a Holder; or (iv) acquires at least twenty percent (20%) of a Holder’s Registrable Securities, provided: (a) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; (b) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including without limitation the provisions of Section 2.12 below; and (c) such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Act. For the purposes of determining the number of shares of Registrable Securities or Common Stock held by a transferee or assignee, the holdings of transferee or assignee (i) that is a subsidiary, parent, partner, limited partner, retired partner, member, retired member or stockholder of a Holder; (ii) that is an Affiliate of the Holder, which means with respect to a limited liability company or a limited liability partnership, a fund or entity managed by the same manager or managing member or general partner or management company or by an entity controlling, controlled by, or under common control with such manager or managing member or general partner or management company; (iii) who is a Holder’s Immediate Family Member; or (iv) that is a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member, shall be aggregated together and with those of the assigning Holder; provided that all assignees and transferees who would not qualify individually for assignment of registration rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices or taking any action under this Article II.

Section 2.11 Limitations on Subsequent Registration Rights. From and after the date of this Agreement and prior to the Company’s Initial Offering, the Company shall not, without the prior written consent of (i) the holders of a majority of the Preferred Stock and ARIAD Common Stock voting together (for purposes of such calculation the Preferred Stock shall be deemed converted into Common Stock in accordance with its terms) and (ii) the holders of a majority of the Series C Preferred Stock (including BBI so long as BBI owns at least one million (1,000,000) shares of Preferred Stock and/or Common Stock (as adjusted for stock splits, stock dividends and similar recapitalization events)), enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such holder or prospective holder the right to include such securities in any registration unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such securities will not reduce the amount of the

17.

Registrable Securities of the Preferred Holders and ARIAD Holder that are included or to demand registration of any securities held by such holder or prospective holder. Notwithstanding the foregoing, the Company shall be permitted with no additional approvals to provide the holder of the Common Stock Purchase Warrant issued by the Company to the Texas Office of Economic Development and Tourism dated September 27, 2007, with the registration rights provided for in such Common Stock Purchase Warrant on the exercise thereof.

Section 2.12 “Market Stand-Off” Agreement. Each Holder hereby agrees that it or he 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 Company’s Initial Offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days) (a) 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 (whether such shares or any such securities are then owned by the Holder or are thereafter acquired), or (b) 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 (a) or (b) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing provisions of this Section 2.12 shall only be applicable to the Holders if all officers, directors and greater than one percent (1%) stockholders of the Company enter into similar agreements. For purposes of clarification and avoidance of doubt, this Section 2.12 and any lock-up agreement executed by (i) BBI or (ii) X. Xxxx Price Associates, Inc. for and on behalf of any Holder managed by X. Xxxx Price Associates, Inc. (a “X. Xxxx Price Managed Holder”) shall not apply to shares of Common Stock purchased by BBI or a X. Xxxx Price Managed Holder or any other account managed by X. Xxxx Price in the Initial Offering or on the open market after the Initial Offering. The underwriters in connection with the Company’s Initial Public Offering are intended third party beneficiaries of this Section 2.12 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in the Company’s Initial Public Offering that are consistent with this Section 2.12 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply to all Holders subject to such agreements pro rata based on the number of shares subject to such agreements. In order to enforce the foregoing covenant, the Company may impose stop transfer instructions with respect to the Registrable Securities of each Preferred Holder and ARIAD Holder and Common Stock of each Common Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period.

Section 2.13 Termination of Registration Rights. No Holder shall be entitled to exercise any right provided for in this Article II after three (3) years following the consummation of the QPO or such earlier time at which all Registrable Securities held by such Holder, as applicable (and any Affiliate of the Holder with whom such Holder must aggregate its or his sales under Rule 144), can be sold without any volume limitations and without registration in compliance with Rule 144 of the Act within a ninety (90) day period.

(a) any representations and warranties to be made by such Investor or ARIAD in connection with the Approved Sale are limited to representations and warranties related to authority, ownership and the ability to convey title to the shares of the Company’s capital stock held by the Investor or ARIAD, including but not limited to representations and warranties that (i) the Investor or ARIAD holds all right, title and interest in and to such shares that such Investor or ARIAD purports to hold, free and clear of all liens and encumbrances, (ii) the obligations of the Investor or ARIAD in connection with the transaction have been duly authorized, if applicable, (iii) the documents to be entered into by the Investor or ARIAD have been duly executed by the Investor or ARIAD and delivered to the acquirer and are enforceable against the Investor or ARIAD in accordance with their respective terms and (iv) neither the execution and delivery of documents to be entered into in connection with the transaction, nor the performance of the Investor’s or ARIAD’s obligations thereunder, will cause a breach or violation of the terms of any agreement, law or judgment, order or decree of any court or governmental agency;

24.

(b) the Investor or ARIAD shall not be liable for the inaccuracy of any representation or warranty made by any other Person in connection with the Approved Sale, other than the Company (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company as well as breach by any Investor or ARIAD of any of identical representations, warranties and covenants provided by all Investors and ARIAD);

(c) the liability for indemnification, if any, of such Investor or ARIAD in the Approved Sale and for the inaccuracy of any representations and warranties made by the Company or its Investors or ARIAD in connection with such Approved Sale, is several and not joint with any other Person (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company as well as breach by any Investor or ARIAD of any of identical representations, warranties and covenants provided by all Investors and ARIAD), and is pro rata in proportion to, and does not exceed, the amount of consideration paid to such Investor or ARIAD in connection with such Approved Sale;

(d) liability shall be limited to such Investor’s or ARIAD’s applicable share (determined based on the respective proceeds payable to each Investor or ARIAD in connection with such Approved Sale in accordance with the provisions of the Third Amended and Restated Certificate of Incorporation) of a negotiated aggregate indemnification amount that applies equally to all Investors and ARIAD but that in no event exceeds the amount of consideration otherwise payable to such Investor or ARIAD in connection with such Approved Sale, except with respect to claims related to fraud by such Investor or ARIAD, the liability for which need not be limited as to such Investor or ARIAD; and

(e) upon the consummation of the Approved Sale, (i) each holder of each class or series of the Company’s capital stock will receive the same form of consideration for their shares of such class or series as is received by other holders in respect of their shares of such same class or series of stock, (ii) each holder of a series of Preferred Stock will receive the same amount of consideration per share of such series of Preferred Stock as is received by other holders in respect of their shares of such same series, (iii) each holder of Common Stock will

25.

receive the same amount of consideration per share of Common Stock as is received by other holders in respect of their shares of Common Stock, and (iv) the aggregate consideration receivable by all holders of the Preferred Stock and Common Stock shall be allocated among the holders of Preferred Stock and Common Stock on the basis of the relative liquidation preferences to which the holders of each respective series of Preferred Stock and the holders of Common Stock are entitled in a Deemed Liquidation Event (assuming for this purpose that the Approved Sale is a Deemed Liquidation Event) in accordance with the Company’s Third Amended and Restated Certificate of Incorporation.

Section 4.4 Irrevocable Proxy. To secure each Investor’s and ARIAD’s obligations to vote their respective Shares in accordance with Section 4.3 of this Agreement, each Investor and ARIAD hereby appoints the Chairman of the Board or the Chief Executive Officer of the Company, or either of them from time to time, or their designees, as such Investor’s or ARIAD’s true and lawful proxy and attorney, with the power to act alone and with full power of substitution, to vote all of such Investor’s Shares and ARIAD’s Shares as set forth in this Agreement and to execute all appropriate instruments consistent with this Agreement on behalf of such Investor or ARIAD if, and only if, such Investor or ARIAD fails to vote all of such Investor’s Shares or ARIAD’s Shares or execute such other instruments in accordance with the provisions of this Agreement within five days of the Company’s or any other party’s written request for such Investor’s or ARIAD’s written consent or signature. The proxy and power granted by each Investor and ARIAD pursuant to this Section are coupled with an interest and are given to secure the performance of such party’s duties under this Agreement. Each such proxy and power will be irrevocable for the term hereof. The proxy and power, so long as any party hereto is an individual, will survive the death, incompetency and disability of such party or any other individual holder of an Investor’s Shares or ARIAD’s Shares, as the case may be, and, so long as any party hereto is an entity, will survive the merger or reorganization of such party or any other entity holding any of an Investor’s Shares or ARIAD’s Shares.

Section 4.5 Termination of Covenants. Notwithstanding anything herein to the contrary, the covenants set forth in this Article IV and Article V shall terminate and be of no further force or effect upon the earlier of (a) the closing of the QPO; (b) a merger or consolidation of the Company (other than one in which stockholders of the Company own a majority (by voting power) of the outstanding shares of the surviving or acquiring corporation); (c) a sale, lease, transfer, or other disposition of all or substantially all of the assets of the Company; or (d) a transfer of shares of capital stock of the Company representing more than fifty percent (50%) of the votes entitled to be cast at a stockholders meeting to a person or entity, or group of persons or entities, that held (in the aggregate) less than ten percent (10%) of the shares of capital stock of the Company immediately before such transfer.

ARTICLE V

PREEMPTIVE RIGHTS AND TRANSFER RESTRICTIONS

Section 5.1 Preemptive Rights.

(a) Subject to the terms and conditions specified in this Section 5.1, the Company hereby grants to each Investor a preemptive right with respect to future sales by the

26.

Company of its Shares. For purposes of this Section 5.1, Investor includes any partners and Affiliates of an Investor. An Investor shall be entitled to apportion the preemptive right hereby granted it among itself and its partners and Affiliates in such proportions as it deems appropriate.

(b) Each time the Company proposes to offer any Shares, the Company shall first make an offering of such Shares to each Investor in accordance with the following provisions:

(i)

The Company shall deliver a notice in accordance with Section 6.6 (“Notice”) to the Investors stating (A) its bona fide intention to offer such Shares, (B) the number of such Shares to be offered, and (C) the price and terms upon which it proposes to offer such Shares.

(ii)

By written notification received by the Company, within twenty (20) calendar days after receipt of the Notice, each Investor may elect to purchase or obtain, at the price and on the terms specified in the Notice, up to that portion of such Shares that equals the proportion that the number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, or issuable upon exercise of all warrants issued by the Company then held, by such Investor bears to the total number of shares of Common Stock of the Company then outstanding (assuming full conversion of all convertible Preferred Stock and full exercise of all warrants to issued by the Company to any Investor). The Company shall promptly, in writing, inform each Investor that elects to purchase all the Shares available to it, him or her (each, a “Fully-Exercising Investor”) of any other Investor’s failure to do likewise. During the ten (10) day period commencing after receipt of such information, each Fully-Exercising Investor shall be entitled to obtain that portion of the Shares for which Investors were entitled to subscribe but which were not subscribed for by the Investors that equals the proportion that the number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, or issuable upon exercise of all warrants to purchase shares of Common Stock issued by the Company then held, by such Fully-Exercising Investor bears to the total number of shares of Common Stock of the Company then held (assuming full conversion of all convertible Preferred Stock and full exercise of all warrants to purchase shares of Common Stock issued by the Company) by all Fully-Exercising Investors who wish to purchase such unsubscribed Shares.

(iii)

If all Shares that Investors are entitled to obtain pursuant to Section 5.1(b)(ii) are not elected to be obtained as provided in Section 5.1(b)(ii) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in Section 5.1(b)(ii)

27.

hereof, offer the remaining unsubscribed portion of such Shares to any person or persons at a price not less than, and upon terms no more favorable to the offeree than those specified in the Notice. If the Company does not enter into an agreement for the sale of the Shares within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first reoffered to the Investors in accordance herewith.

(iv)

The preemptive rights in this Section 5.1 shall not be applicable to (A) the issuance or sale of securities to employees or directors of, or consultants or advisors to, the Company or any of its subsidiaries pursuant to a plan, agreement or arrangement approved by the Board of Directors of the Company, including a majority of the Preferred Directors; (B) the issuance of securities in a QPO; (C) the issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities; (D) the issuance of securities by reason of a dividend, stock split, split-up or other distribution; (E) the issuance of securities pursuant to the acquisition of another corporation by the Company by merger, purchase of substantially all of the assets or other reorganization or to a joint venture agreement, provided that such issuances are approved by the Board of Directors, including a majority of the Preferred Directors; (F) the issuance of securities to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction approved by the Board of Directors, including a majority of the Preferred Directors; (G) the issuance of Common Stock to ARIAD pursuant to and in accordance with the ARIAD Stock Purchase Agreement or Section 4 of the ARIAD Investor Rights Agreement; or (H) the issuance of securities pursuant to the Purchase Agreement.

Section 5.2 Common Holder Right of First Offer.

(a) Each time any Common Holder (the “Selling Common Holder”) proposes to Transfer (other than a Transfer by operation of law, including but not limited to as a result of a divorce, bankruptcy or death of a Common Holder or any other involuntary Transfer) any or all of the Shares standing in such Selling Common Holder’s name or owned by such Selling Common Holder during the term of this Agreement (the “Offered Securities”), such Selling Common Holder shall first offer to the Company and then to the Preferred Holders the right to purchase all or any portion of the Offered Securities in accordance with the following provisions:

(i)

Such Selling Common Holder shall deliver a written notice (a “Sale Notice”) to the Company and to each Preferred Holder setting forth an irrevocable written offer to sell all of the Offered

28.

Securities which the Selling Common Holder desires or is required to Transfer and stating (A) such Selling Common Holder’s bona fide intention to Transfer the Offered Securities, (B) the name and the address of the proposed transferee, (C) the number of Shares to be Transferred, and (D) the purchase price per Share and terms of payment for which the Selling Common Holder proposes to Transfer the Offered Securities.

(ii)

The Company shall have twenty (20) days after the delivery of the Sale Notice to notify such Selling Common Holder in writing (a “Purchase Notice”) of its election or rejection to purchase all or any portion of the Offered Securities. The Purchase Notice shall identify the number of Offered Securities that the Company desires to purchase from the Selling Common Holder. The Company shall have the right to purchase any or all of the Offered Securities offered for sale as set forth in the Company’s Purchase Notice. A copy of such Purchase Notice shall also be delivered to all Preferred Holders simultaneously with that provided to the Selling Common Holder. If the Company so elects to purchase all or a part of the Offered Securities as set forth herein, the Company shall be obligated to purchase such securities on the terms and conditions set forth in the Sale Notice. The Company shall close its purchase within sixty (60) days of the delivery of the Sale Notice. If the Sale Notice provides for the payment of non-cash consideration, the Company, at its option, may pay the consideration in cash equal to its good faith estimate of the present fair market value of the non-cash consideration offered.

(iii)

If the Company does not elect to purchase all of the Offered Securities in accordance with Section 5.2(a)(ii) above, the Selling Common Holder shall deliver written notice to all of the Preferred Holders to that effect not later than ten (10) days following the Selling Common Holder’s receipt of a Purchase Notice from the Company or the expiration of the Company’s rights to purchase the Offered Securities (a “Secondary Notice”). Each Preferred Holder shall have twenty (20) days after the delivery of the Secondary Notice to notify such Selling Common Holder in writing (via a Purchase Notice) of its election or rejection to purchase all (or a part) of the Offered Securities. The Purchase Notice shall identify the total number of Offered Securities that such Preferred Holder desires to purchase from the Selling Common Holder, which amount designated may be greater than such Preferred Holder’s pro rata portion of the Offered Securities. The Preferred Holders shall have the right to purchase such portion of the Offered Securities offered for sale as the Shares owned (on a fully diluted basis assuming conversion of the Preferred Stock and assuming exercise of any warrant to purchase shares of Common Stock issued by the Company to any Preferred Holder) by such Preferred Holder at such time shall bear to the outstanding Shares owned (on a fully diluted basis assuming conversion of the Preferred Stock and assuming exercise of any warrant to purchase shares of Common Stock

29.

issued by the Company to any Preferred Holder) by all the other Preferred Holders. A copy of such Purchase Notice shall also be delivered to the Company simultaneously with that provided to the Selling Common Holder. If each Preferred Holder so elects to purchase all or a part of such Preferred Holder’s pro rata portion of the Offered Securities as set forth herein, such Preferred Holder shall be obligated to purchase such securities on the terms and conditions set forth in the Sale Notice. If any Preferred Holder elects not to purchase all of such Preferred Holder’s pro rata portion of the Offered Securities, then any such remaining shares of Offered Securities may be purchased on a pro rata basis by those other Preferred Holders that indicated on their respective Purchase Notice that they wanted to purchase a number of Offered Securities that is greater than their respective pro rata portion of the Offered Securities, in the same manner described above. The Preferred Holders shall close their respective purchases within sixty (60) days of the delivery of the Secondary Notice (an “Expiration Date”). If the Sale Notice provides for the payment of non-cash consideration, each Preferred Holder, at its option, may pay the consideration in cash equal to its good faith estimate of the present fair market value of the non-cash consideration offered.

(iv)

If the Company and the Preferred Holders do not elect to purchase all of the Offered Securities designated in the Sale Notice, then no shares of Offered Securities shall be sold to the Company or the Preferred Holders, and the Selling Common Holder may transfer the remaining amount of the Offered Securities to the proposed transferee set forth on the Sale Notice, provided such transfer (A) is completed within sixty (60) days after the Expiration Date, (B) is made at the price and terms designated in the Sale Notice, and (C) the proposed transferee agrees to be bound by the terms and provisions of this Agreement and to become a party to this Agreement to the same extent as the Selling Common Holder immediately upon receipt of the Offered Securities. If the Offered Securities are not so transferred within such sixty (60) day time period, the Sale Notice given to the Company and the Preferred Holders shall be deemed to have expired and a new notice shall be required prior to any other or subsequent transfer of the Offered Securities.

(v)

Any transferee of Common Stock in a transaction other than a transaction described in Section 5.2(a) shall, as a condition to the

30.

registration of the transfer on the stock transfer records of the Company and its recognition by the Company as a valid transfer, execute a counterpart of this Agreement or such other documentation as shall be reasonably requested by the Company pursuant to which such transferee shall agree to be bound by the provisions of this Agreement.

(b) Notwithstanding anything in Section 5.2(a) to the contrary, a Common Holder may Transfer Shares to a Common Holder’s Immediate Family Member or to a trust established for the sole benefit of the Common Holder or the Common Holder’s Immediate Family Member or Members; provided that the Common Holder notifies the Company of such Transfer not less than ten (10) nor more than ninety (90) days prior to the Transfer and that the proposed transferee agrees to be bound by the terms and provisions of this Agreement and to become a party to this Agreement to the same extent as the Common Holder immediately upon the receipt of such Shares.

Section 5.3 Right of Co-Sale.

(a) As used in this Section 5.3, the term “Sale” means a sale or transfer made or agreed to by a Common Holder in the manner described in the first sentence of the following paragraph, and the term “Consummation Date” means the date fixed for the consummation of a Sale.

(b) Except with respect to a Transfer pursuant to Section 5.2(b), in the event any Common Holder or group of Common Holders (the “Selling Group”) shall desire to sell all or any portion of their respective Shares to any third party in a transaction described in Section 5.2(a), and the Company and the Preferred Holders have not exercised their Rights of First Refusal as to such Shares in accordance with Section 5.2, each Preferred Holder and the ARIAD Holder shall have the option to require the Selling Group to purchase, or cause the purchase of, such number of Shares owned (on an as-converted basis) by such Preferred Holder and ARIAD Holder equal to the number of Shares to be transferred multiplied by a fraction, the numerator of which will be the number of shares of Common Stock that were issued or are issuable upon conversion of the Preferred Stock then held by such Preferred Holder or the ARIAD Common Stock, as the case may be, and the denominator of which will be sum of the total number of shares of Common Stock that were issued or are issuable upon conversion of the Preferred Stock held by all Preferred Holders and the ARIAD Common Stock, upon the same terms and conditions as those of the Sale as set forth in the written offer to the Preferred Holders and the Company as provided in Section 5.2 hereof. The option described herein shall be exercised by the giving of written notice of the exercise of such option to the Selling Group not more than ten (10) days after the date of receipt by the Preferred Holders and the ARIAD Holder of the Secondary Notice as set forth in Section 5.2. The Selling Group shall, on the Consummation Date and conditioned upon and contemporaneously with the Sale, purchase, or cause the purchase by the purchasers of, such Shares of the Preferred Holders and the ARIAD Holder upon terms and conditions the same as those of the Sale. If any Preferred Holder or the ARIAD Holder exercises the option under this Section 5.3, and if the Selling Group has elected to purchase (rather than cause the purchase of) the Shares owned by the Preferred Holders and the ARIAD Holder, then the Selling Group must resell to the purchasers the Shares so purchased

31.

contemporaneously with the Sale and upon the same terms and conditions as those of the Sale. If the Selling Group shall fail to so purchase, or cause the purchase of, the Shares of the Preferred Holders and the ARIAD Holder as provided in this Section 5.3, then the Selling Group may not consummate the Sale.

THE SALE, TRANSFER, OR OTHER DISPOSITION AND VOTING OF SUCH SECURITIES IS SUBJECT TO THE TERMS OF SUCH AGREEMENT, AND SUCH SECURITIES ARE TRANSFERABLE ONLY UPON PROOF TO THE COMPANY OF COMPLIANCE THEREWITH.”

Section 6.14 No “Bad Actor” Disqualification.

(a) The Company has exercised reasonable care to determine whether any Company Covered Person (as defined below) is subject to any of the “bad actor” disqualifications described in Rule 506(d)(1)(i) through (viii), as modified by Rules 506(d)(2) and (d)(3), under the Act (each, a “Disqualification Event”). To the Company’s knowledge, no Company Covered Person is subject to a Disqualification Event. The Company has complied, to the extent required, with any disclosure obligations under Rule 506(e) under the Act. For purposes of this Agreement, “Company Covered Persons” are those persons specified in Rule 506(d)(1) under the Act; provided, however, that Company Covered Persons do not include (i) any Series C Holder, (ii) any person or entity that is deemed to be an affiliated issuer of the Company solely as a result of the relationship between the Company and any Investor or ARIAD or (iii) any director of the Company that has been designated by any Investor or ARIAD.

(b) Each Series C Holder represents and warrants that neither (i) such person, nor (ii) any entity that controls such person or is under the control of, or under common control with, such person, nor (iii) any director of the Company that has been designated by such person, is subject to any Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) under the Act and disclosed in writing in reasonable detail to the Company. No party to this Agreement will select a designee that is subject to any Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Act, in which case such party will promptly disclose in writing to the Company and other parties to this Agreement any and all information necessary for the Company to determine whether Rule 506(d)(2)(ii) or (iii) or (d)(3) applies.

(c) Each party to this Agreement represents that it has exercised reasonable care to determine the accuracy of the representation made by it in either Section 6.14(a) or (b) above as applicable, and agrees to notify each other party to this Agreement if it becomes aware of any fact that makes the representation given by it hereunder inaccurate.

35.

(d) Notwithstanding any other provision in this Agreement to the contrary, no party to this Agreement will be required to vote for any director or proposed director who is subject to a Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Act.
