In connection with any transfer of Shares, other than pursuant to an effective registration statement or to Rule 144 (or an analogous successor thereto), the Company may require the transferor to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration under the Securities Act.

(b) The Purchaser agrees that certificates initially representing the Shares shall bear a restrictive legend (and, with respect to Shares held in book-entry form, the

Transfer Agent will record such a legend or other notation on the share register of the Company) in substantially the following form:

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

(c) Removal of Legends. The restrictive legend set forth in Section 5.1.1(b) above shall be removed and the Company shall issue a certificate without such restrictive legend or any other restrictive legend to the holder of the applicable Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the Transfer Agent in accordance with the Transfer Agent Instructions, at such time as Shares are being transferred, (i) if a registration statement covering the resale of the Shares is effective under the Securities Act, (ii) at the request of the holder (regardless of whether such Shares are then being resold), if the Shares are eligible for sale under Rule 144 (or an analogous successor thereto), or (iii) if the holder provides the Company with a legal opinion (and the documents upon which the legal opinion is based) to the effect that the legend is not required under applicable requirements of the Securities Act (including controlling judicial interpretations and pronouncements issued by the Staff of the SEC) as contemplated by the last sentence of Section 5.1.1(a) hereof. In connection with the legend removal event related to any Shares contemplated by the foregoing sentence, the Company will no later than two (2) Trading Days following the delivery by the Purchaser to the Company or the Transfer Agent (if delivery is made to the Transfer Agent a copy shall be contemporaneously delivered to the Company) of (i) a legended certificate representing such Shares (and, in the case of a requested transfer, endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect transfer), and (ii) an opinion of counsel only to the extent required by the last sentence of Section 5.1.1(a) hereof, direct the Transfer Agent to deliver to such Purchaser a certificate representing such Shares that is free from all restrictive and other legends. Notwithstanding the foregoing, the Company shall direct the Transfer Agent to remove the transfer restrictions and legends applicable to the Shares and deliver to the Purchaser certificates representing the Shares free from all restrictive legends or other transfer restrictions upon: (y) the written request of the Purchaser, within two (2) Trading Days of such request, at such time as the Shares may be transferred without the requirement that the Company be in compliance with the public information requirements and without volume or manner-of-sale restrictions under Rule 144 (or an analogous successor thereto) or (z) if the holder provides the Company with a legal opinion (and the documents upon which the legal opinion is based) to the effect that the legend is not

required under applicable requirements of the Securities Act (including controlling judicial interpretations and pronouncements issued by the Staff of the SEC) as contemplated by the last sentence of Section 5.1.1(a) hereof. Certificates for Shares free from all restrictive legends may be transmitted by the Transfer Agent to the Purchaser by crediting the account of the Purchaser’s primary broker with the Transfer Agent as directed by the Purchaser. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 5.1.1.

(a) If and for so long as the Purchaser’s investment in the Shares is equal to or exceeds five percent (5%) of the Company’s then issued and outstanding Common Stock, the Purchaser hereby agrees to execute and promptly deliver to the Company a customary lock-up agreement restricting the disposition of the Shares as may be requested by the Company, or the managing underwriter(s) or placement agent(s), as the case may be, in connection with a public offering or private placement of the Company’s Common Stock; provided, that the Purchaser shall be in no way obligated to sign such a lock-up agreement unless, in connection with such financing, (i) the Company agrees in writing with the Purchaser not commence another public offering or private placement until any lock-up agreement executed by the Purchaser pursuant to this Section 5.1.2(a) is no longer effective, (ii) all of the Company’s executive officers and directors and beneficial owners of five (5%) or more of the Common Stock have first signed a lock-up agreement, and (iii) no such lock-up agreement signed by any of the executive officers, directors or beneficial owners of five (5%) or more of the Common Stock contains terms more favorable to the locked-up party than the lock-up agreement proposed to be signed by the Purchaser. The Company shall deliver the form of requested lock-up agreement to the Purchaser at least five (5) Trading Days prior to the closing of such financing event, but in no event sooner than the date that the Company, or the managing underwriter(s) or placement agent(s), as the case may be, solicit indications of interest from potential investors in such financing event. In no event shall such lock-up agreement restrict the Purchaser for a period longer than ninety (90) days after the date of the final prospectus (if the financing event is a public offering) or the date of the purchase agreement (if the financing event is a private placement), as the case may be. Any such lock-up agreement shall be drafted to terminate upon the earlier of (i)(A) the date the proposed financing is abandoned or (B) the date the underwriting agreement or the purchase agreement related to the financing event, as the case may be, is terminated and (ii) thirty (30) calendar days from the date such lock-up agreement was executed in the event the underwriting agreement or purchase agreement related to the financing, as the case may be, is not executed. Notwithstanding the foregoing, following the expiration of the Strategic Lock-Up Period (as defined below), the Purchaser shall neither be restricted from selling shares pursuant to a lock-up signed pursuant to this Section 5.1.2(a) for a period that exceeds 90 days during any 360-day period nor shall a restricted period contained within a lock-up proposed to be executed by the Purchaser pursuant to this Section 5.1.2(a) be less than thirty (30) consecutive days in duration.

(b) The Purchaser acknowledges that the Company shall impose stop-transfer instructions with respect to the Shares subject to the restriction set forth in Section 5.1.2(a) until the end of such “lock-up” period.

(c) The Company acknowledges and agrees that, unless the Purchaser is required to sign a lock-up agreement pursuant to Section 5.1.2(a), the Company will not disclose its plans to conduct a financing event to the Purchaser that would, absent the Purchaser’s consent, cause the Purchaser to be in possession of material non-public information that would require the Purchaser to refrain from trading in the Common Stock. If the Purchaser is required to sign a lock-up agreement pursuant to Section 5.1.2(a) and receives any notice from the Company regarding the Company’s plans to conduct a financing event as described in Section 5.1.2(a) above, the Purchaser agrees to treat such notice of the proposed financing event as material non-public information and refrain from trading in the Common Stock until the financing event is abandoned or completed and disclosed; provided, that, absent an agreement to the contrary with the Purchaser, within thirty (30) calendar days of such notice, the Company shall either inform the Purchaser in writing that it is no longer in possession of such material non-public information or cleanse the Purchaser of such material non-public information via publicly disclose of the material non-public information.

(d) Except as otherwise permitted in this Agreement, until the 365th day following the Initial Closing Date, the Purchaser will not transfer any of the Shares purchased hereunder for value without the Company’s consent (such 365-day period, the “Strategic Lock-Up Period”); provided, that the restrictions set forth in this Section 5.1.2(d) shall in no way prohibit transfers of the Company’s securities by the Purchaser (i) to any affiliate of the Purchaser, including to a corporation, member, partner, trust or other business entity that is a direct or indirect affiliate of the Purchaser, or to an investment fund or other entity that manages or directly or indirectly controls the Purchaser, (ii) as part of a distribution, transfer or distribution by the Purchaser to its stockholders, members, partners, beneficiaries (or the estates thereof) or its other equity holders, but, in either case (i) or (ii), only if the transferee agrees in writing to be bound to transfer restrictions consistent with this Section 5.1.2(d), (iii) to the Company, (iv) by operation of law, including pursuant to orders of a court or regulatory agency, or (v) pursuant to a tender offer made to all holders of Common Stock or bona fide merger, consolidation or transaction whereby all or substantially all of the Common Stock is acquired by a third-party (including, without limitation, the entering into of any lock-up, voting or similar agreement pursuant to which the undersigned may agree to transfer, sell, tender or otherwise dispose of shares of Common Stock or other such securities in connection with such transaction, or vote any shares of Common Stock or other securities in favor of any such transaction).

5.2 Furnishing of Information. Until the date that the Purchaser may no longer holds Registrable Securities, the Company covenants to use its reasonable best efforts to (i) file in a timely manner all reports and other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder and (ii) make available information necessary to comply with Rule 144 with respect to resales of the Shares under the Securities Act, at all times, to the extent required from time to time to enable the Purchaser to resell Shares without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144 (if available with respect to resales of the Shares), as such rule may be amended from time to time or (B) any other rules or regulations now existing or hereafter adopted by the SEC. The Company further covenants that it will take such

further action as any holder of Shares may reasonably request to satisfy the provisions of this Section 5.2.

5.3 Reservation of Shares. The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to this Agreement in such amounts as may then be required to fulfill its obligation under this Agreement.

5.4 Nasdaq Matters.

5.5 Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Shares as required under Regulation D and to provide a copy thereof, promptly upon request of the Purchaser. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Shares for, sale to the Purchaser under applicable securities or “blue sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of the Purchaser.

5.6 Further Assurances. Subject to the terms and conditions of this Agreement, each of the Company and the Purchaser agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and assist the other party hereto in doing, all things reasonably necessary, proper or advisable to obtain satisfaction of the conditions precedent to the consummation of the transactions contemplated at the Closings: (a) obtaining all necessary Consents and the making of all filings and the taking of all steps as may be necessary to obtain Consent from, or to avoid an Action by, any Governmental Authority, (b) the defending of any Actions challenging this Agreement or any other Transaction Agreements or the consummation of the transactions contemplated hereby or thereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed, and (c) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement and the other Transaction Agreements.

5.7 Non-Public Information. Except as contemplated by the Collaboration Agreement, the Company covenants and agrees that neither it, nor any other Person acting on its behalf will provide Purchaser or its agents or counsel with any information that constitutes material non-public information, unless prior thereto Purchaser shall have entered into a written agreement with the Company regarding the confidentiality and use of such information. The Company understands and confirms that Purchaser will be relying on the foregoing covenant in effecting transactions in securities of the Company.

5.8 Securities Law Disclosure; Publicity. No public release or announcement concerning the transactions contemplated hereby or by any other Transaction Agreement, including the public filing of any Transaction Agreement pursuant to applicable securities Laws, shall be issued by the Company or the Purchaser without the prior consent of the

Company (in the case of a release or announcement by the Purchaser) or the Purchaser (in the case of a release or announcement by the Company) (which consents shall not be unreasonably withheld, conditioned or delayed), except for any such public filing, release or announcement as may be required by securities Law or other applicable Law or the applicable rules or regulations of any securities exchange or securities market, in which case the Company or the Purchaser, as the case may be, shall allow the Purchaser or the Company, as applicable, reasonable time to comment on such public filing, release or announcement in advance of such filing or issuance and the disclosing party shall consider the other party’s comments in good faith.

5.9 Integration. The Purchaser acknowledges that the Company may issue additional shares of Common Stock after the date hereof; provided, however, that the Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Securities Act) that would be integrated with the offer or sale of the Shares to be issued to the Purchaser hereunder (i) in a manner that would require the registration under the Securities Act of the sale of the Shares or (ii) for purposes of the rules and regulations of the Trading Market.

5.10 Use of Proceeds. The net proceeds received by the Company from the Closings shall be used for general corporate purposes at the direction of the Board of Directors.

5.11 Registration Rights. The Company covenants and agrees as follows:

(a) If the Purchaser holds Registrable Securities (as defined below) upon the expiration of the Strategic Lock-Up Period (the “Registration Deadline”) or, in either case, such earlier time as the Company in its sole discretion may agree in writing, or such later time as the Purchaser in its sole discretion may agree in writing, then the Company shall file a registration statement to register the resale of the applicable Unregistered Registrable Securities (as defined below) on a registration statement on Form S-3 (or such other form appropriate for such purpose if the Company does not meet the eligibility requirements for use of Form S-3) (a “Resale Registration Statement”) under the Securities Act and use reasonable best efforts to have such registration statement declared effective and maintain the effectiveness of such registration statement for a period ending on the date the Purchaser no longer holds Registrable Securities (as defined below).

(b) The Company shall take reasonable best efforts to register all Unregistered Registrable Securities on Form S-3 if such form is available for use by the Company, provided that if Registrable Securities are registered for resale on Form S-1, the Company shall maintain the effectiveness of such registration statement then in effect until such time as a registration statement on Form S-3 registering the resale of the Registrable Securities has been declared effective by the SEC.

(c) The Company shall use reasonable best efforts to have each Resale Registration Statement declared effective by the SEC as soon as practicable following a Filing Deadline, but in no event shall a Resale Registration Statement covering Unregistered Registrable Securities be declared effective by the SEC later than the earlier of (i) ten (10) Business Days after the SEC informs the Company that no review of such Resale Registration Statement will be made or that the SEC has no further comments on such Resale Registration

Statement and (ii) the forty-fifth (45th) day after an applicable Registration Deadline (or the ninetieth (80th) day if the SEC reviews such Resale Registration Statement). The Company shall notify the Purchaser by facsimile or e-mail as promptly as practicable, and in any event, within forty-eight (48) hours, after any Resale Registration Statement is declared effective and shall simultaneously provide the Purchaser with access to a copy of any related prospectus to be used in connection with the sale or other disposition of the securities covered thereby.

(d) All expenses, other than Selling Expenses (as defined below), incurred in connection with registrations, filings or qualifications pursuant to this Section 5.11, including all registration, filing and qualification fees; printers’ and accounting fees; fees and disbursements of counsel for the Company; and the reasonable fees and disbursements, shall be borne and paid by the Company. All Selling Expenses shall be borne by the Purchaser; or if there are other selling shareholders with shares being registered pursuant to such registration statement, then pro rata by the selling shareholders based on the number of shares sold by such selling shareholder in the offering.

(e) For the purposes of this Section 5.11,

(i) “Losses” means any loss, damage, claim or liability (joint or several) to which a party hereto may become subject under the Securities Act, the Exchange Act, or other federal or state law, insofar as such loss, damage, claim or liability.

(ii) “Registrable Securities” means, at any time, the Shares held by Purchaser including, without limitation, any Common Stock paid, issued or distributed in respect of any such Shares by way of stock dividend, stock split or distribution, or in connection with a combination of shares, recapitalization, reorganization, merger or consolidation, or otherwise, but excluding Common Stock acquired in the open market before or after the date hereof; provided, however, that the Shares will not be “Registrable Securities” (A) after such Shares have been sold pursuant to an effective registration statement or in compliance with Rule 144 or (B) when certificates evidencing all of the Shares issuable to the Purchaser under this Agreement have been so issued and the remaining Shares then held by the Purchaser have been reissued to the Purchaser without restrictive legends and are then free from any other restrictions on transfer.

(iii) “Selling Expenses” means the fees and disbursements of counsel for the Purchaser.

(iv) “Unregistered Registrable Securities” means any and all Registrable Securities outstanding at the Registration Deadline that have not been registered for resale pursuant to a then-effective registration statement filed with the Commission.

(f) Indemnification.

(i) To the extent permitted by law, the Company will indemnify and hold harmless the Purchaser, and the partners, members, officers and directors of the Purchaser and each Person, if any, who controls the Purchaser (collectively, “Purchaser Indemnified Parties”), against any Losses, arising out of and is based upon: (A) any untrue statement or alleged untrue statement of a material fact contained in any registration statement of

the Company registering the resale of the Registrable Securities, including any preliminary prospectus or final prospectus contained therein, documents and filings incorporated by reference therein or any amendments or supplements thereto or (B) an omission or alleged omission to state in such registration statement a material fact required to be stated therein, or necessary to make the statements therein not misleading; provided, however, that the Company shall not be liable for any Losses arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Purchaser for use in any registration statement of the Company registering the resale of the Registrable Securities, including any preliminary prospectus or final prospectus contained therein, documents and filings incorporated by reference therein and any amendments or supplements thereto, provided, however, that the Company acknowledges and agrees that the only such written information furnished to the Company by the Purchaser for use in any such registration statement of the Company is the Purchaser’s information included in its beneficial ownership footnote and the amount of the Company’s securities beneficially owned by the Purchaser (but excluding percentages) (collectively, the “Purchaser Information”).

(ii) To the extent permitted by law, the Purchaser will indemnify and hold harmless the Company, its directors, officers, agents and employees and each person who “controls” the Company (collectively, “Company Indemnified Parties”), against any Losses, arising out of and is based upon: (A) any untrue statement or alleged untrue statement of a material fact contained in any registration statement of the Company registering the resale of the Registrable Securities, including any preliminary prospectus or final prospectus contained therein, documents and filings incorporated by reference therein and any amendments or supplements thereto or (B) an omission or alleged omission to state in such registration statement a material fact required to be stated therein, or necessary to make the statements therein not misleading; but only to the extent that such untrue statements or omissions or alleged untrue statements or omissions are based solely upon Purchaser Information. In no event shall the liability of the Purchaser hereunder be in excess of the public offering price of all such Registrable Securities offered and sold by the Purchaser pursuant to such registration statement.

(iii) A Person from who indemnity is sought hereunder (an “Indemnifying Party”) will pay to a Person entitled to indemnity hereunder (an “Indemnified Party”) any legal or other reasonable and documented expenses incurred thereby in connection with investigating or defending any claim or proceeding from which Losses may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 5.11(f) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld.

(g) Promptly after receipt by the Indemnified Party under this Section 5.11 of notice of the commencement of any action (including any governmental action) for which an Indemnified Party may be entitled to indemnification hereunder, the Indemnified Party will, if a claim in respect thereof is to be made against the Indemnifying Party under this Section5.11, give the Indemnifying Party notice of the commencement thereof. The Indemnifying Party shall have the right to participate in such action and, to the extent the Indemnifying Party so desires, and to assume the defense thereof with counsel mutually satisfactory to the Indemnified Parties; provided, however, that the Indemnified Parties shall

have the right to retain one separate counsel for all such Indemnified Parties, with the reasonable and documented fees and expenses to be paid by the Indemnifying Party, if representation of the Indemnified Parties by the counsel retained by the Company would be inappropriate due to actual or potential conflict of interest between the Indemnified Parties and the Indemnifying Party. The failure to give notice to the Indemnifying Party within a reasonable time of the commencement of any such action shall relieve the Indemnifying Party of any liability to the Indemnified Parties under this Section 5.11, only to the extent that such failure materially prejudices the Indemnifying Party ability to defend such action. The failure to give notice to the Indemnifying Party will not relieve it of any liability that it may have to the Indemnified Party otherwise than under this Section 5.11.

(h) To provide for just and equitable contribution to joint liability under the Securities Act in any case in which contribution under the Securities Act may be required on the part of the Indemnified Parties, then such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses 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 and each Indemnified Party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the Indemnifying Party and each Indemnified Party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to information supplied by the Indemnifying Party or by a 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 (x) the Purchaser will not be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by the Purchaser pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(i) The parties acknowledge that the provisions of Sections 5.11(e), (f), (g) and (h) hereof may be superseded by indemnification and contribution provisions included in an underwriting agreement, placement agency agreement or similar document that is executed by the Company and the Purchaser in connection with a public offering or private placement of securities, as the case may be.
