required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that this representation and warranty shall not apply to statements in or omissions in the General Disclosure Package made in reliance upon and in conformity with the Agents’ Information.

Each of the Company and its subsidiaries has fulfilled and performed in all material respects all of its obligations with respect to such Permits and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other material impairment of the rights of the Company thereunder. Except as may be required under the Securities Act and state Blue Sky laws, no other Permits are required to enter into, deliver and perform this Agreement and to issue and sell the Securities.

the PRC Intellectual Property Authority or other foreign patent office, as applicable; and each such pending Patent is being diligently prosecuted by the Company or its subsidiaries; to the extent that a Patent was acquired by the Company or its subsidiaries pursuant to an assignment, such assignment is valid, binding and enforceable, and all PRC governmental approvals in respect of such assignment have been validly obtained and are in full force and effect; the Patents have been duly maintained and are in full force and in effect; no security interests or other liens have been created on or with respect to any of the Patents.

The certificates evidencing the Securities are in due and proper legal form and have been duly authorized for issuance by the Company. All of the issued and outstanding shares of Common Stock have been duly and validly issued and are fully paid and nonassessable.

The Company has reserved and kept available for the exercise of the Warrants such number of authorized but unissued shares as are sufficient to permit the exercise in full of the Warrants. The Shares, when delivered by the Company pursuant to this Agreement, and the Warrant Shares, when issued upon exercise of the Warrants, will be duly and validly issued, fully paid and nonassessable and none of them will be issued in violation of any preemptive or other similar right. Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there is no outstanding option, warrant or other right calling for the issuance of, and there is no commitment, plan or arrangement to issue, any share of stock of the Company or any of its subsidiaries or any security convertible into, or exercisable or exchangeable for, such stock.

               (y) No transaction has occurred between or among the Company and any of its officers or directors, shareholders or any affiliate or affiliates of any such officer or director or shareholder that is required to be described in and is not described in the Registration Statement, the General Disclosure Package and the Prospectus.

Additionally, the Company acknowledges and agrees that the Placement Agents have not and will not advise the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company has consulted with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Placement Agents shall have no responsibility or liability to the Company or any other person with respect thereto, whether arising prior to or after the date hereof.

The Company has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping. The Company represents that is has satisfied and agrees that it will satisfy the conditions set forth in Rule 433 of the Rules to avoid a requirement to file with the Commission any Roadshow.

          5. Indemnification.

               (a) The Company agrees to indemnify and hold harmless each Placement Agent and its affiliates and their respective present and former directors, officers, employees, agents and controlling persons within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each such person, including each Placement Agent, a “PA Indemnified Party”) to the extent fully permitted by law from and against any losses, claims,

damages and liabilities, joint or several (collectively, the “Damages”), to which such PA Indemnified Party may become subject in connection with or otherwise relating to or arising from (i) any transaction contemplated by this Agreement or the engagement of or performance of services by a PA Indemnified Party hereunder or (ii) an untrue statement or an alleged untrue statement of a material fact in the Registration Statement, General Disclosure Package, the Prospectus and any Roadshow or the omission or alleged omission in the Registration Statement, General Disclosure Package, the Prospectus and any Roadshow to state a material fact necessary in order to make a statement not misleading in light of the circumstances under which it was made, and will reimburse each PA Indemnified Party for all reasonable fees and expenses (including the reasonable fees and expenses of counsel) (collectively, “Expenses”) as incurred in connection with investigating, preparing or defending any threatened or pending claim, action, proceeding or investigation (collectively, the “Proceedings”) arising therefrom, whether or not such PA Indemnified Party is a formal party to such Proceedings, and in enforcing this Agreement; provided, however, that such indemnity shall not inure to the benefit of any Placement Agent (or any person controlling such Placement Agent) on account of any losses, claims, damages or liabilities arising from the sale of the Securities if such untrue statement or omission or alleged untrue statement or omission was made in any preliminary prospectus, Registration Statement, the General Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or such amendment or supplement thereto, or in any Blue Sky Application in reliance upon and in conformity with any of the Agents’ Information. The Placement Agents, severally and not jointly, will indemnify and hold harmless the Company and its affiliates and their respective present and former directors, officers, employees, agents and controlling persons within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each such person, including the Company, a “Company Indemnified Party,” and together with the PA Indemnified Parties, each an “Indemnified Party”) to the extent fully permitted by law from and against any Damages to which such Company Indemnified Party may become subject in connection with or otherwise relating to or arising from any of the Agents’ Information and will reimburse each Company Indemnified Party for all Expenses as incurred in connection with investigating, preparing or defending any Proceedings arising therefrom, whether or not such Company Indemnified Party is a formal party to such Proceedings, and in enforcing this Agreement.

               (b) The Company agrees not to enter into any waiver, release or settlement of any Proceeding (whether or not any of the Placement Agents or any other Indemnified Party is a formal party to such Proceeding) in respect of which indemnification may be sought hereunder without the prior written consent of each Placement Agent (which consent will not be unreasonably withheld), unless such waiver, release or settlement (i) includes an unconditional release of each Placement Agent and each Indemnified Party from all liability arising out of such Proceeding and (ii) does not contain any factual or legal admission by or with respect to any Indemnified Party or any adverse statement with respect to the character, professionalism, expertise or reputation of any Indemnified Party or any action or inaction of any Indemnified Party.

               (c) The indemnity, reimbursement and contribution obligations of the Company hereunder will be in addition to any liability which the Company may have at common law or otherwise to any Indemnified Party and will be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company or an Indemnified Party.

               (d) Any party that proposes to assert the right to be indemnified under this Section will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section, notify each such indemnifying party of the commencement of such action, suit or proceeding, enclosing a copy of all papers served. No indemnification provided for in Section 5(a) shall be available to any party who shall fail to give notice as provided in this Section 5(d) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was prejudiced by the failure to give such notice but the omission so to notify such indemnifying party of any such action, suit or proceeding shall not relieve it from any liability that it may have to any indemnified party for contribution or otherwise than under this Section. In case any such action, suit or proceeding 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 reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and the approval by the indemnified party of such counsel, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses, except as provided below and except for the reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. The indemnified party shall have the right to employ its counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party has been authorized in writing by the indemnifying parties, (ii) the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it which are different from or in addition to those available to the indemnifying party (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party) or (iii) the indemnifying parties shall not have employed counsel to assume the defense of such action within a reasonable time after notice of the commencement thereof, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying parties. An indemnifying party shall not be liable for any settlement of any action, suit, and proceeding or claim affected without its written consent, which consent shall not be unreasonably withheld or delayed.

          6. Contribution. If, for any reason other than in accordance with this Agreement, the indemnity provided for in Section 5(a) is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless, then the Company will contribute to the amount paid or payable by an Indemnified Party as a result of such Damages (including all Expenses incurred) in such proportion as is appropriate to reflect the relative benefits to the Company and/or its stockholders on the one hand, and each Placement Agent on the other hand, in connection with the matters covered by this Agreement or, if the foregoing allocation is not permitted by applicable law, not only such relative benefits but also the relative faults of such parties as well as any relevant equitable considerations. The Company agrees that for purposes of this paragraph the relative benefits to the Company and/or its stockholders and each Placement

Agent in connection with the matters covered by this Agreement will be deemed to be in the same proportion that the total value paid or received or to be paid or received by the Company and/or its stockholders in connection with the transactions contemplated by this Agreement, whether or not consummated, bears to the fees paid to each Placement Agent under this Agreement; provided, that in no event will the total contribution of all Indemnified Parties to all such Damages exceed the amount of fees actually received and retained by each Placement Agent under this Agreement (excluding any amounts received by each Placement Agent as reimbursement of expenses). Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission or any alleged conduct relates to information provided by the Company or other conduct by the Company (or its employees or other agents) on the one hand, or by each Placement, on the other hand. 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. For purposes of this Section 6, each person, if any, who controls a Placement Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Placement Agent, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of the Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 6, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 7. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent. The Placement Agents’ obligations to contribute pursuant to this Section 6 are several in proportion to their respective amounts of placement agent fees each has actually received pursuant to this Agreement and not joint.

          7. Termination.

               (a) This Agreement may be terminated at any time prior to the Closing Date by Oppenheimer on behalf of the Placement Agents by notifying the Company at any time at or before the Closing Date in the absolute discretion of Oppenheimer if: (i) there has occurred any material adverse change in the securities markets or any event, act or occurrence that has materially disrupted, or in the opinion of Oppenheimer, will in the future materially disrupt, the securities markets or there shall be such a material adverse change in general financial, political or economic conditions or the effect of international conditions on the financial markets in the United States or the PRC is such as to make it, in the judgment of Oppenheimer, inadvisable or impracticable to market the Securities and the Warrant Shares or enforce contracts for the sale of the Securities and the Warrant Shares; (ii) there has occurred any outbreak or material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States or the PRC is such as to make it, in the judgment of Oppenheimer, inadvisable or impracticable to market the Securities and the Warrant Shares or enforce contracts for the sale of the Shares; (iii) trading in the shares of Common Stock or any securities of the Company has

been suspended or materially limited by the Commission or trading generally on the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities have been required, by any of said exchanges or by such system or by order of the Commission, FINRA, or any other governmental or regulatory authority; (iv) a banking moratorium has been declared by any state or Federal authority; or (v) in the judgment of Oppenheimer, there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the assets, properties, financial condition, or in the results of operations, business affairs or business prospects of the Company and its subsidiaries considered as a whole, whether or not arising in the ordinary course of business.

               (b) If this Agreement is terminated pursuant to any of its provisions, the Company shall not be under any liability to any Placement Agent, and no Placement Agent shall be under any liability to the Company; provided, however, that if this Agreement is terminated by the Placement Agents because of any failure, refusal or inability on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company will reimburse the Placement Agents for all out-of-pocket expenses (including all fees and disbursements of their counsel) incurred by them in connection with this Agreement and the proposed sale of the Securities and the Warrant Shares or in contemplation of performing their obligations hereunder.

          8. Miscellaneous. The respective agreements, representations, warranties, indemnities and other statements of the Company and the Placement Agents, as set forth in this Agreement or made by or on behalf of them pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Placement Agent or the Company or any of their respective officers, directors or controlling persons referred to in Sections 5 and 6 hereof, and shall survive delivery of and payment for the Shares. In addition, the provisions of Sections 4(b), 5, 6 and 7 shall survive the termination or cancellation of this Agreement.

          This Agreement has been and is made for the benefit of the Placement Agents, the Company and their respective successors and assigns, and, to the extent expressed herein, for the benefit of persons controlling any of the Placement Agents, or the Company, and directors and officers of the Company, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term “successors and assigns” shall not include any Investor merely because of such purchase.

          All notices and communications hereunder shall be in writing and mailed or delivered or by telephone or telegraph if subsequently confirmed in writing, (a) if to the Placement Agents, to (1) Oppenheimer & Co. Inc., 300 Madison Avenue, 4^th Floor, New York, New York 10017 Attention: Andrew MacInnes, (2) Susquehanna Financial Group, LLLP 401 City Ave, Suite 220, Bala Cynwyd, Pennsylvania 19004 and (3) Philadelphia Brokerage Corporation, 2 Radnor Corporate Center, Suite 111, 100 Matsonford Road, Radnor, Pennsylvania 19087 and (b) if to the Company, to Chief Financial Officer at BMP Sunstone Corporation, 600 W.

Investor acknowledges that the Investor will be required to bear the cost, if any, of printing the Prospectus.

          7. No offer by the Investor to buy any Securities will be accepted and no part of the purchase price therefor will be delivered to the Company until the Company has accepted such offer by countersigning a copy of this Agreement, and any such offer may be withdrawn or revoked by the Investor, without obligation or commitment of any kind, at any time prior to the Company (or the Placement Agents on behalf of the Company) sending (orally, in writing, or by electronic mail) notice of its acceptance of such offer. An indication of interest will involve no obligation or commitment of any kind until this Agreement is accepted and countersigned by or on behalf of the Company.
