6. Covenants.

(a) The Company covenants and agrees with the Underwriters as follows:

(i) During the period beginning on the date hereof and ending on the later of the Closing Date or such date as determined by the Underwriters the Final Prospectus is no longer required by law to be delivered in connection with sales by an underwriter or dealer (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement, including any Rule 462 Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus, the Company shall furnish to the Underwriters for review and comment a copy of each such proposed amendment or supplement, and the Company shall not file any such proposed amendment or supplement to which the Underwriters reasonably object.

If the Commission shall enter any such stop order at any time during the Prospectus Delivery Period, the Company will use its reasonable efforts to obtain the lifting of such order at the earliest possible moment. Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b), 430A and 430B, as applicable, under the Securities Act and will use its reasonable efforts to confirm that any filings made by the Company under Rule 424(b) or Rule 433 were received in a timely manner by the Commission (without reliance on Rule 424(b)(8) or 164(b) of the Securities Act).

If during such period any event occurs the result of which the Final Prospectus (or if the Final Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package ) would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary or appropriate in the opinion of the Company or its counsel or the Underwriters or counsel for Xxxx Capital Partners, LLC to amend the Registration Statement or supplement the Final Prospectus (or if the Final Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package ) to comply with the Securities Act, the Company will promptly notify the Underwriters and will amend the Registration Statement or supplement the Final Prospectus (or if the Final Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) so as to correct such statement or omission or effect such compliance.

(iv) The Company shall take or cause to be taken all necessary action to qualify the Shares for sale under the securities laws of such U.S. jurisdictions as the Underwriters reasonably designate and to continue such qualifications in effect so long as required for the distribution of the Shares, except that the Company shall not be required in connection therewith to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified, to execute a general consent to service of process in any state or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject.

(v) The Company will furnish to the Underwriters and counsel for Xxxx Capital Partners, LLC copies of the Registration Statement, and each Prospectus, and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Underwriters may from time to time reasonably request.

(vi) The Company will make generally available to its security holders as soon as practicable, but in any event not later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement (which need not be audited) covering a 12-month period that shall satisfy the provisions of Section 11(a) and Rule 158 of the Securities Act.

In addition to the foregoing, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, the Company will reimburse the Underwriters for up to $200,000 for their expenses actually incurred in connection with its investigation, preparing to market and marketing the Shares in contemplation of performing its obligations hereunder and in connection with the purchase and sale of the Shares contemplated hereby, inclusive of all fees and expenses of Underwriters’ counsel (the “Underwriters’ Expenses”).

(viii) The Company intends to apply the net proceeds from the sale of the Shares to be sold by it hereunder for the purposes set forth in the Time of Sale Disclosure Package and in the Final Prospectus.

(ix) The Company will not take, directly or indirectly, during the Prospectus Delivery Period, any action designed to or which might reasonably be expected to cause or result in, or that has constituted, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares.

(x) The Company will not distribute any prospectus or other offering material in connection with the offering and sale of the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act.

(xi) The Company hereby agrees that, without the prior written consent of Xxxx Capital Partners, LLC, it will not, during the period ending 90 days after the date hereof (“Lock-Up Period”): (i) offer, pledge, issue, sell, contract to sell, purchase, contract to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock; or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; or (iii) file any registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock. The restrictions contained in the preceding sentence shall not apply to: (1) the Shares to be sold hereunder; (2) the issuance of Common Stock upon the exercise of options or warrants or upon the conversion of any convertible securities disclosed as outstanding in the Registration Statement (excluding exhibits thereto) or the Final Prospectus; (3) the issuance of warrants or employee stock options not exercisable during the Lock-Up Period and the grant of restricted stock awards or restricted stock units pursuant to equity incentive plans described in the Registration Statement (excluding exhibits thereto) and the Final Prospectus; (4) warrants issued in the ordinary course that are not exercisable during the Lock-Up Period; or (5) the filing of resale registration statements pursuant to existing registration rights obligations under the agreements on Schedule VII. Notwithstanding the foregoing, if (x) the Company issues an earnings release or material news, or a material event relating to the Company occurs, during the last 17 days of the Lock-Up Period, or (y) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this clause shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, unless Xxxx Capital Partners, LLC waives such extension in writing.

7. Conditions of the Underwriters’ Obligations. The obligations of the Underwriters hereunder to purchase the Shares are subject to the accuracy, as of the date hereof and at the Closing Date (as if made at the Closing Date), of and compliance with all representations, warranties and agreements of the Company contained herein, the performance by the Company of its obligations hereunder and the following additional conditions:

(b) The Underwriters will indemnify, defend and hold harmless the Company and its affiliates, directors, officers and employees, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Underwriters), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto, or arise out of or are based upon 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, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Time of Sale Disclosure Package, the Final Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by the Underwriters specifically for use in the preparation thereof, and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with defending against any such loss, claim, damage, liability or action.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure. In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof; provided, however, that if (i) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (ii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party), or (iii) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, the indemnified party shall have the right to employ a single counsel to represent it in any claim in respect of which indemnity may be sought under subsection (a) or (b) of this Section 8, in which event the reasonable fees and expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the indemnified party as incurred.

The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is a party or could be named and indemnity was or would be sought hereunder by such indemnified party, unless such settlement, compromise or consent (a) includes an unconditional release of such indemnified party from all liability for claims that are the subject matter of such action, suit or proceeding and (b) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering and sale of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Final Prospectus. The relative fault shall be 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 Company or the Underwriters and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the first sentence of this subsection (d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of 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 against any action or claim that is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Underwriters shall not be required to contribute any amount in excess of the amount of the Underwriters’ commissions referenced in Section 5(a) actually received by the Underwriters pursuant to this Agreement. 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 obligations of the Company under this Section 8 shall be in addition to any liability that the Company may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to each person, if any, who controls the Underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability that the Underwriters may otherwise have and the benefits of such obligations shall extend, upon the same terms and conditions, to the Company and its officers, directors and each person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act.

(f) For purposes of this Agreement, the Underwriters confirm, and the Company acknowledges, that there is no information concerning the Underwriters furnished in writing to the Company by the Underwriters specifically for preparation of or inclusion in the Registration Statement, the Time of Sale Disclosure Package, or the Final Prospectus, other than the statements set forth in the last paragraph on the cover page of the Final Prospectus and the statements set forth in the “Underwriting” section of the Final Prospectus and Time of Sale Disclosure Package, only insofar as such statements relate to the amount of selling concession and re-allowance or to over-allotment and related activities that may be undertaken by the Underwriters.

9. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company herein or in certificates delivered pursuant hereto, including, but not limited to, the agreements of the Underwriters and the Company contained in Section 6(a)(vii) and Section 8 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriters or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Shares to and by the Underwriters hereunder.

10. Termination of this Agreement.

Any such termination shall be without liability of any party to any other party except that the provisions of Section 6(a)(vii) and Section 8 hereof shall at all times be effective and shall survive such termination.

(b) If the Underwriters elect to terminate this Agreement as provided in this Section, the Company shall be notified promptly by the Underwriters by telephone, confirmed by letter.

This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns and the controlling persons, officers and directors referred to in Section 8. Nothing in this Agreement is intended or shall be construed to give to any other person, firm or corporation any legal or equitable remedy or claim under or in respect of this Agreement or any provision herein contained.

In addition to rendering legal advice and assistance to the Company in the course of the preparation of the Registration Statement and the Time of Sale Disclosure Package and the Final Prospectus, involving, among other things, discussions and inquiries concerning various legal matters and the review of certain corporate records, documents and proceedings, we also participated in conferences with certain officers and other representatives of the Company, its independent certified public accountants and you and your counsel, at which the contents of the Registration Statement, the Time of Sale Disclosure Package and the Final Prospectus, the information incorporated in the Time of Sale Disclosure Package and the Final Prospectus and related matters were discussed. We have also reviewed and relied upon certain corporate records and documents of the Company, letters from counsel and accountants, and oral and written statements and certificates of officers and other representatives of the Company and others as to the existence and consequences of certain factual and other matters.

The purpose of our professional engagement was not to establish or confirm factual matters or financial or quantitative information. Therefore, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements or information contained or incorporated by reference in the Registration Statement, the Time of Sale Disclosure Package or the Final Prospectus and have not made, or undertaken any obligation to make, an independent check or verification thereof. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Time of Sale Disclosure Package and the Final Prospectus involve matters of a non-legal nature.

10. On August 8, 2006, six PRC regulatory agencies, namely, the PRC Ministry of Commerce, the State Assets Supervision and Administration Commission, the State Administration for Taxation, the State Administration for Industry and Commerce, the China Securities Regulatory Commission (the “CSRC”), and the State Administration of Foreign Exchange, jointly adopted the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors (the “M&A Rule”), which became effective on September 8, 2006. The M&A Rule purports, among others, to require offshore special purpose vehicles (the “SPVs”), controlled directly or indirectly by PRC companies or individuals, for purposes of overseas listing of their interests in PRC domestic companies, to obtain the approval of the CSRC prior to publicly listing the securities of the SPVs on an overseas stock exchange. On September 21, 2006, pursuant to the M&A Rule and other PRC Laws, the CSRC, in its official website, promulgated relevant guidance with respect to the issues of indirect issuing, listing and trading of domestic enterprises’ securities on overseas stock exchanges, including a list of application materials with respect to the listing on overseas stock exchanges by SPVs. Based on our understanding of current PRC Laws, we believe that CSRC approval is not required in the context of this Transaction.

The sale of the Shares and the compliance by the Company with all of the provisions of the Underwriting Agreement and the consummation of the Transaction do not result in any violation of the provisions of the Articles of Association, or Business License of any of the PRC Group Companies or any PRC Laws, including without limitation the M&A Rule.

13. No governmental authorization of any governmental agency in the PRC is required for the consummation of the Transaction, other than those already obtained.

14. Although we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Final Prospectus, we have no reason to believe that any introduction or description of PRC Laws or any legal conclusion based on PRC Laws included in the Registration Statement, when it became effective, the Time of Sale Disclosure Package, as of the date of the Underwriting Agreement and the date hereof, or the Final Prospectus, at the time the Final Prospectus was filed with the Commission or at the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein not misleading.

15. The entry into, and performance or enforcement of the Underwriting Agreement in accordance with its terms will not subject the Underwriter to any requirement to be licensed or otherwise qualified to do business in the PRC, nor will the Underwriter be deemed to be resident, domiciled, carrying on business or subject to taxation through an establishment or place in the PRC or in breach of any PRC Laws by reason of entry into, performance or enforcement of the Underwriting Agreement or the Transaction.

If these activities are regarded by PRC government authorities as “human genetic resources research and development activities,” additional approvals by PRC government authorities will be required” (collectively, the “Regulatory Information”) that summarize the provisions of the PRC Food, Drug and Cosmetic Act (“PFDCA”) and implementing regulations, are accurate summaries in all material respects of the provisions purported to be summarized under such captions and do not omit to summarize applicable material provisions of the PFDCA or its implementing regulations necessary to make those statements not misleading.

18. Nothing has come to the attention of us, without making any independent investigation, that causes us to believe that (A) the Regulatory Information, or (B) the statements under the caption “Business – Governmental Regulation” (collectively, the “Regulatory Statements”) contained or contains an untrue statement of a material fact related to State Food and Drug Administration (the “SFDA”) matters or omitted or omits to state a material fact related to SFDA matters required to be stated therein or necessary to make the statements therein not misleading.
