(b)Due Execution. All corporate actions on the part of Parent and Purchaser, and their respective officers, directors and stockholders necessary for the authorization, execution and delivery of this Agreement and payment of the Purchase Price have been taken, or will be taken prior to the Closing. This Agreement has been duly authorized, executed and delivered by Parent and Purchaser, and, upon due execution and delivery by the Company, will constitute a valid and legally binding obligation of Parent and Purchaser, enforceable against Parent and Purchaser in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally or by equitable principles.

(c)Investment Representations. In connection with the offer, purchase and sale of the Shares, Purchaser makes the following representations:

(i)Purchaser is acquiring the Shares for its own account for the purpose of investment and not with a view to or for sale in connection with any distribution thereof, and has no present intention to effect, or any present or contemplated plan, agreement, undertaking, arrangement, obligation, indebtedness, or commitment providing for, any distribution of the Shares.

(ii)Purchaser has carefully reviewed the representations concerning the Company contained in this Agreement and has made detailed inquiry concerning the Company, its business and its personnel.

(iii)Purchaser understands that the Shares have not been registered under the Securities Act or any applicable state securities laws and, consequently, Purchaser may have to bear the risk of owning the Shares for an indefinite period of time because the Shares may not be transferred unless (x) the resale of the Shares is registered pursuant to an effective registration statement under the Securities Act; (y) Purchaser has delivered to the Company an opinion of counsel (in form, substance and scope customary for opinions of counsel in comparable transactions and satisfactory to the Company) to the effect that the Shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration; or (z) the Shares are sold or transferred pursuant to Rule 144.

(iv)Purchaser has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Shares to be purchased hereunder.

(v)Purchaser is an “accredited investor” as defined in Rule 501(a) of the rules and regulations promulgated under the Securities Act.

(d)Certain Fees. No broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based on arrangements made by Parent or Purchaser.

(e)Governmental Consents. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any Governmental Authority on the part of Purchaser is required in connection with the consummation of the transactions contemplated by this Agreement, except for the PRC Approval.

(f)Legends.

(i)In connection with the issuance and sale of the Shares, Purchaser understands that each of the Shares, whether certificated or in book-entry form, will be endorsed with the following legend:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.”

(ii)Notwithstanding the foregoing, the Company shall use its commercially reasonable efforts to cause the Transfer Agent to remove the foregoing legend within three (3) Business Days after the Company’s receipt of a written request for legend removal by Purchaser, which request may be made following the expiration of the Lock-Up Period and: (x) any time after the date on which the Registration Statement is declared effective by the Commission (the “Effectiveness Date”), (y) upon any sale of such securities effected in accordance with Rule 144, or (z) at such time as when the Shares may be sold pursuant to Rule 144 without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) under the Securities Act and without volume or manner-of-sale restrictions. In the case of clauses (y) and (z) above, Purchaser’s written request for legend removal shall be accompanied by such evidence as reasonably requested by the Company or Transfer Agent that a public sale or transfer of such Shares may be made without registration under the Securities Act. To the extent that the foregoing legend is being removed pursuant to the foregoing clause (x) and prior to a sale of the legended securities, Purchaser covenants that it will only sell, transfer or otherwise dispose of such securities pursuant to the Registration Statement and subject to the limitations set forth in Article IV.

The Company acknowledges and agrees that the representations contained in Section 3.2 shall not modify, amend or affect Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in the License Agreement or any other document or instrument executed and/or delivered in connection with this Agreement or the License Agreement or the consummation of the transactions contemplated hereby.

ARTICLE IV.
REGISTRATION RIGHTS

4.1Registration of the Shares. The Company shall file with the Commission, as soon as practicable but in no event later than 90 days prior to the first anniversary of the Closing Date (the “Filing Deadline”), a Registration Statement covering the resale of the full amount of the Shares to the public by Purchaser. The Company shall use commercially reasonable efforts to cause the Registration Statement covering the Shares to be declared effective by the Commission as soon as practicable, but in no event later than the date (the “Effectiveness Deadline”), which shall be either: (i) in the event that the Commission does not review the Registration Statement, 90 days after the Closing Date (but in any event, no later than three Business Days following the Commission indicating a “no-review” decision on the Registration Statement), or (ii) in the event that the Commission reviews the Registration Statement or notifies the Company that the Registration Statement cannot be declared effective prior to the resolution of any comments related to filings made by the Company with the Commission or confidential treatment requests made by the Company, 120 days after the Closing Date (but in any event, no later than three Business Days following the Commission indicating that it has no further comments on the Registration Statement). Notwithstanding the above, if the Company has received comments from the Commission or the Staff regarding the Registration Statement, then the Company shall use its reasonable best efforts to resolve any such comments as promptly as practicable. The Company shall cause such Registration Statement to remain effective under the Securities Act until all Shares covered by such Registration Statement have been sold or may be sold without volume restrictions pursuant to Rule 144. The Company shall promptly notify Purchaser of the effectiveness of such Registration Statement after the Company confirms effectiveness with the Commission. The Company hereby covenants and agrees to use reasonable commercial efforts to maintain its eligibility to make filings with the Commission on Form S-3 until one or more registrations statements covering the resale of all of the Shares shall have been filed with, and declared effective by, the Commission pursuant to the terms and conditions of this Agreement.

4.2Rule 415; Cutback. If at any time the staff of the Commission (the “Staff”) takes the position that the offering of some or all of the Shares in a Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires any Purchaser to be named as an “underwriter,” the Company shall use its reasonable best efforts to persuade the Commission that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that Purchaser is not an “underwriter.” For the avoidance of doubt, “reasonable best efforts” shall not require the Company to institute or maintain any action, suit or proceeding against the Commission or any member of the Staff. In the event that, despite the Company’s reasonable best efforts and compliance with the terms of this Section 4.2, the Staff refuses to alter its position, the Company shall: (a) remove from the Registration Statement

such portion of the Shares (the “Cut Back Shares”) and/or (b) agree to such restrictions and limitations on the registration and resale of the Shares as the Staff may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name any Purchaser as an “underwriter” in such Registration Statement without the prior written consent of such Purchaser. No liquidated damages shall accrue as to any Cut Back Shares until such date as the Company is able to effect the registration of such Cut Back Shares in accordance with any SEC Restrictions (such date, the “Restriction Termination Date” of such Cut Back Shares). From and after the Restriction Termination Date applicable to any Cut Back Shares, all of the provisions of this ARTICLE IV (including the liquidated damages provisions) shall again be applicable to such Cut Back Shares; provided, however, that (x) the Filing Deadline for the Registration Statement including such Cut Back Shares shall be ten Business Days after such Restriction Termination Date and (y) the Effectiveness Deadline with respect to such Cut Back Shares shall be the 90th day immediately after the Restriction Termination Date or the 120th day if the Staff reviews such Registration Statement (but in any event no later than three Business Days from the Staff indicating it has no further comments on such Registration Statement).

4.3Registration Covenant. Purchaser covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of the Shares pursuant to a Registration Statement. The Company shall comply in all material respects with all applicable rules and regulations of the Commission applicable to the filing of a Registration Statement.

4.4Rule 144. With a view to making available to Purchaser the benefits of Rule 144, the Company agrees to:

(a)use its reasonable best efforts to make and keep public information available, as those terms are understood and defined in Rule 144, during the Reporting Period;

(b)use its reasonable best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act; and

(c)furnish to Purchaser, so long as Purchaser owns Shares, promptly upon request during the Reporting Period: (i) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act; and (ii) a statement of how many shares of Common Stock are then issued and outstanding.

4.5Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement.

(a)Subject to Section 4.2, if either: (a) a Registration Statement covering all of the Shares required to be covered thereby and required to be filed by the Company pursuant to this Agreement is: (i) not filed with the Commission on or before the Filing Deadline (a “Filing Failure”), or (ii) not declared effective by the Commission on or

before the Effectiveness Deadline (an “Effectiveness Failure”), or (b) on any day during the Reporting Period and after the Effectiveness Date, sales of all of the Shares required to be included on such Registration Statement cannot be made (other than (i) during a Grace Period or (ii) if the Registration Statement is on Form S-1, for a period of 15 days following the date the Company files a post-effective amendment to incorporate the Company’s Annual Report on Form 10-K) (a “Maintenance Failure”), then, in satisfaction of the damages to any holder of Shares by reason of any such delay in or reduction of its ability to sell the underlying shares of Common Stock, the Company shall pay to Purchaser relating to such Registration Statement an amount in cash equal to 1.0% of the Purchase Price on each of the following dates: (x) the day of a Filing Failure and on every thirtieth day (prorated for periods totaling less than 30 days) thereafter until such Filing Failure is cured; (y) the day of an Effectiveness Failure and on every thirtieth day (prorated for periods totaling less than 30 days) thereafter until such Effectiveness Failure is cured; and (z) the initial day of a Maintenance Failure and on every thirtieth day (prorated for periods totaling less than 30 days) thereafter until such Maintenance Failure is cured. The payments to which Purchaser shall be entitled pursuant to this Section 4.5 are referred to herein as “Registration Delay Payments”; provided that no Registration Delay Payments shall be required following the termination of the Reporting Period, and, provided, further, that in no event shall the aggregate Registration Delay Payments accruing under this Section 4.5 exceed 6.0% of Purchaser’s interest in the aggregate Purchase Price (i.e., corresponding to a total delay of six months). The first such Registration Delay Payment shall be paid within three Business Days after the event or failure giving rise to such Registration Delay Payment occurred and all other Registration Delay Payments shall be paid on the earlier of (I) the last day of the calendar month during which such Registration Delay Payments are incurred and (II) the third Business Day after the event or failure giving rise to the Registration Delay Payments is cured.

(b)Notwithstanding anything to the contrary herein, at any time after the Effectiveness Date, the Company may delay the disclosure of material, non-public information concerning the Company that would be required to be made in a registration statement filed with the Commission so that such registration statement does not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading the disclosure of which at the time is not, in the good faith opinion of the Company and its counsel, in the best interest of the Company and, in the opinion of counsel to the Company, would not be required to be made at such time but for the continued use of such registration statement (a “Grace Period”); provided, that the Company shall promptly: (i) notify Purchaser in writing of the existence of material, non-public information giving rise to a Grace Period (provided that in each notice the Company will not disclose the content of such material, non-public information to Purchaser) and the date on which the Grace Period will begin, and (ii) notify Purchaser in writing of the date on which the Grace Period ends; and, provided further, that the Grace Periods shall not exceed an aggregate of 30 Trading Days during any 365-day period and the first day of any Grace Period must be at least 15 days after the last day of any prior Grace Period. For purposes of determining the length of a Grace Period above, the Grace Period shall begin on and include the date Purchaser receives the notice referred to in clause: (i) and shall end on and include the later of the

date Purchaser receives the notice referred to in clause (ii) and the date referred to in such notice. Upon expiration of the Grace Period, the Company shall again be bound by Section 4.6(c) with respect to the information giving rise thereto unless such material, non-public information is no longer applicable. Notwithstanding anything to the contrary, the Company shall cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of Purchaser in accordance with the terms of this Agreement in connection with any sale of Registrable Securities with respect to which a Purchaser has entered into a contract for sale, and delivered a copy of the prospectus included as part of the applicable Registration Statement (unless an exemption from such prospectus delivery requirement exists), prior to Purchaser’s receipt of the notice of a Grace Period and for which Purchaser has not yet settled.

4.6Registration Procedures.

(a)In connection with the filing by the Company of a Registration Statement covering the Shares, the Company shall furnish to Purchaser (i) a copy of the prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act and (ii) such other documents as Purchaser may reasonably request, in order to facilitate the public sale or other disposition of the Shares.

(b)The Company shall use commercially reasonable efforts to register or qualify the Shares covered by a Registration Statement under the securities laws of each state of the United States as Purchaser shall reasonably request; provided, however, that the Company shall not be required in connection with this subsection (b) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction.

(c)If the Company has delivered preliminary or final prospectuses to Purchaser and after having done so the prospectus is amended or supplemented to comply with the requirements of the Securities Act, the Company shall promptly notify Purchaser and, if requested by the Company, Purchaser shall immediately cease making offers or sales of the Shares covered by a Registration Statement and return all prospectuses to the Company. The Company shall promptly provide Purchaser with revised or supplemented prospectuses and, following receipt of the revised or supplemented prospectuses, Purchaser shall be free to resume making offers and sales of the Shares under such Registration Statement.

(d)The Company shall be entitled to include in a Registration Statement the shares of Common Stock held by other shareholders of the Company, provided such other shares of Common Stock are excluded first from such Registration Statement in order to comply with any applicable laws or request from any Governmental Authority, or in the case of an underwritten offering, in order to comply with a cutback request of any underwriter.

(e)The Company shall pay all expenses incurred in connection with the preparation and filing of such Registration Statement pursuant to this ARTICLE IV, including all registration and filing fees and printer, legal and accounting fees related thereto, but excluding (i) any brokerage fees, selling commissions or underwriting

discounts incurred by Purchasers in connection with sales under any Registration Statement covering the Shares and (ii) the fees and expenses of counsel retained by Purchaser.

(f)The Company shall use commercially reasonable efforts to avoid the issuance of any order suspending the effectiveness of a Registration Statement, or any suspension of the qualifications (or exemption from qualification) of any of the Shares covered by a Registration Statement for sale in any jurisdiction. The Company shall advise Purchaser promptly after it shall receive notice of any stop order or issuance of any order by the Commission delaying or suspending the effectiveness of a Registration Statement covering the Shares or of the initiation of any proceeding for that purpose, and it will promptly use commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued.

4.7Indemnification.

(a)The Company agrees to indemnify and hold harmless Purchaser and its respective shareholder, directors, officers, and Affiliates (collectively, the “Purchaser Indemnified Party”) from and against any losses, claims, damages, liabilities, judgments, fines, obligations, and reasonable expenses, including but not limited to any investigative, legal and other expenses reasonably incurred in connection with, and any amounts paid in settlement of, any pending legal action or proceeding (collectively, “Losses”) arise out of, or are based on (i) any breach of any representation or warranty of the Company contained in this Agreement; (ii) any violation or nonperformance, partial or total, of any covenant or agreement of the Company contained in this Agreement; or (iii) any untrue statement or alleged misstatement of a material fact contained in any Registration Statement covering the Shares or in any preliminary prospectus or final prospectus contained in such Registration Statement, or any amendment or supplement to such Registration Statement, or the omission or alleged omission to state 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 in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement, preliminary prospectus or prospectus, or any amendment or supplement in reliance upon and in conformity with written information furnished to the Company by or on behalf of Purchasers or controlling person specifically for use in the preparation thereof or any statement or omission in any prospectus that is corrected in any subsequent prospectus that was delivered to Purchaser prior to the pertinent sale or sales by Purchaser.

(b)Purchaser agrees to indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company, from and against any Losses, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based on (i) any breach of any representation or warranty of the Purchaser or the Parent contained in this Agreement; (ii) any violation or nonperformance, partial or total,

of any covenant or agreement of the Purchaser or the Parent contained in this Agreement; or (iii) any untrue statement or alleged misstatement of a material fact contained in any Registration Statement covering the Shares or in any preliminary prospectus, final prospectus contained in such Registration Statement, or any amendment or supplement to such Registration Statement or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if such untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of Purchaser specifically for use in preparation of the Registration Statement, prospectus, amendment or supplement; provided, however, that Purchaser’s obligation to indemnify the Company shall be limited to the Purchase Price.

(c)Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 4.7, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 4.7 (except to the extent that such omission materially and adversely affects the indemnifying party’s ability to defend such action). Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person, the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any Affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; provided, however, that such consent shall not be unreasonably withheld. No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could have been a party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding.

(d)If the indemnification provided for in this Section 4.7 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in

respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and Purchaser on the other hand, in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or Purchaser on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), Purchaser shall not be required to contribute any amount in excess of the amount by which the net amount received by Purchaser from the sale of the Shares to which such loss relates exceeds the amount of any damages which Purchaser has otherwise been required to pay by reason of such untrue statement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e)The rights and obligations of the Company and Purchaser under this Section 4.7 shall survive the termination of this Agreement.

Excluding any transfers of Shares between Purchaser and any of its Affiliates, during the twelve (12) months immediately following the Closing Date (the “Lock-Up Period”), Purchaser shall not, and shall not cause any other holder of the Shares to, without the prior written consent of the Company, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Shares or enter into a transaction which would have the same effect; provided that, if the Company undergoes a Change in Control the Board of Directors has recommended that the Company’s shareholder accept or a tender offer made by a third party, Purchaser shall not be excluded and shall be entitled to participate in such Change in Control or tender offer as a shareholder of the Company.

(b)Market Stand-Off Agreement. During the Lock-Up Period, Purchaser agrees that in connection with any registration of the Company’s securities that, upon the request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Purchaser will not sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Shares without the prior written consent of the Company or such underwriters, as the case may be, for such period of time within the Lock-Up Period from the effective date of such registration as the Company or the underwriters may specify.

(c)Remedies. Without prejudice to the rights and remedies otherwise available to the Parties, the Company shall be entitled to equitable relief by way of injunction if Purchaser breaches any of the provisions of this Section 5.1.

5.2Voting. During the Lock-Up Period, Purchaser shall vote, or cause to be voted, all shares of Common Stock then beneficially owned by Purchaser, in accordance with the recommendation of the Board of Directors on any matters presented to the Company’s stockholders with respect to any of the Company’s equity incentive plans or compensation matters, in each case, that apply to employees of the Company generally.

5.3Non-Public Information. Except as contemplated by the License Agreement, the Company covenants and agrees that, following the Closing, neither it, nor any other Person acting on its behalf, will provide Purchaser or its agents or counsel with any information that the Company believes 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 shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

5.5 Listing of Common Stock, No Integrated Offerings. The Company shall take no action designed to, or which to the knowledge of the Company is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act.

The Company further agrees, if the Company applies to have the Common Stock traded on any other trading market, it will include in such application all of the Shares, and will take such other action as is necessary to cause all of the Shares to be listed on such other trading market as promptly as possible. The Company will take all action reasonably necessary to continue the listing and trading of its Common Stock, including the Shares, on Nasdaq and will comply in all material respects with the Company’s reporting, filing and other obligations under the Bylaws or rules of Nasdaq. The Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the Common Stock from Nasdaq nor has the Company received in the past twelve (12) months any notification that the Commission

or Nasdaq is contemplating terminating such registration or listing. The Company currently meets the continuing eligibility requirements for listing on Nasdaq.

The Company agrees to file with the Commission in a timely manner all reports and other filings required of the Company under the Securities Act and the Exchange Act. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Shares in a manner that would require the registration under the Securities Act of the sale of the Shares to Purchaser or that would be integrated with the offer or sale of the Shares for purposes of the rules and regulations of Nasdaq.
