(b) Each Selling Stockholder, severally and not jointly, agrees to indemnify and hold harmless the Underwriter, each person, if any, who controls the Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of the Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show or the Prospectus or any amendment or supplement thereto, or caused by any 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 but only with respect to any Selling Stockholder Information contained in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show or the Prospectus or any amendment or supplement thereto. The liability of each Selling Stockholder under the indemnity agreement contained in this paragraph, the contribution provisions of this Section 11, and in respect of any claim in respect of a breach of the representations and warranties of such Selling Stockholder contained in Sections 2(f) and 2(g) hereof, shall be limited to an amount equal to the aggregate Purchase Price of the Shares sold by such Selling Stockholder under this Agreement.

(c) The Underwriter agrees to indemnify and hold harmless the Company, the Selling Stockholders, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any Selling Stockholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to the Underwriter furnished to the Company in writing by the Underwriter through you expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show or the Prospectus or any amendment or supplement thereto. The parties hereto understand and agree that the only such information concerning the Underwriter furnished by the Underwriter consists of the following information in the Time of Sale Prospectus and the Prospectus: the name of Underwriter under the heading “Underwriting,” the information contained in the first sentence of the third paragraph under the heading “Underwriting” discussing dealers’ concession, the last sentence in the third paragraph under the heading “Underwriting” (only in respect of the Underwriter named therein), the information contained in the thirteenth paragraph under the heading “Underwriting” discussing possible stabilization measures and the address of the Underwriter appearing in the fifteenth paragraph under the heading “Underwriting.”

In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11(a), 11(b) or 11(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Underwriter and all persons, if any, who control the Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of the Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Selling Stockholders and all persons, if any, who control the Selling Stockholders within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriter and such control persons and affiliates of the Underwriter, such firm shall be designated in writing by the Underwriter. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Stockholders and such control persons of the Selling Stockholders, such firm shall be designated in writing by an executive officer of any Selling Stockholder. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld), 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 from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 11(a), 11(b) or 11(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 11(d)(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 11(d)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand 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 and the Selling Stockholders on the one hand and the Underwriter on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Selling Stockholders and the total underwriting discounts and commissions received by the Underwriter bear to the aggregate public offering price of the Shares. The relative fault of the Company and the Selling Stockholders on the one hand and the Underwriter on the other hand 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 and the Selling Stockholders or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The liability of each Selling Stockholder under the contribution agreement contained in this paragraph and the indemnity contained in Section 11(b), and in respect of any claim in respect of a breach of the representations and warranties of such Selling Stockholder contained in Sections 2(f) and 2(g) hereof, shall be limited to an amount equal to the aggregate Purchase Price of the Securities sold by such Selling Stockholder under this Agreement.

(e) The Company, the Selling Stockholders and the Underwriter agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriter were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(d) shall be deemed to include, subject to the limitations set forth above, 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 Section 11, (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no Selling Stockholder shall be required to contribute an amount in excess of the amounts by which the proceeds of this offering (before payment of expenses but after deducting underwriting discounts and commissions) received by such Selling Stockholder exceeds the amount of any damages that such Selling Stockholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company and the Selling Stockholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Underwriter, any person controlling the Underwriter or any affiliate of the Underwriter or, any Selling Stockholder or any person controlling any Selling Stockholder, the officers or directors of the Company or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

12. Termination. The Underwriter may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT, the NASDAQ Global Market, or any other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States, PRC or Hong Kong shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State, PRC or Hong Kong authorities, or (v) there shall have occurred any material adverse change in the financial markets in the United States, PRC, Hong Kong or the international financial markets, any outbreak or escalation of hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

13. Survival of Certain Representations and Warranties. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers, of the Selling Stockholders, and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriter, the Company, any Selling Stockholder, or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares.

14. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If this Agreement shall be terminated by the Underwriter, because of any failure or refusal on the part of any of the Company and the Selling Stockholders to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any of the Company and the Selling Stockholders shall be unable to perform its obligations under this Agreement, such defaulting party will reimburse the Underwriter with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by the Underwriter in connection with this Agreement or the offering contemplated hereunder.

15. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Selling Stockholders, on the one hand, and the Underwriter on the other hand, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) Each of the Company and the Selling Stockholders acknowledges that in connection with the offering of the Shares: (i) the Underwriter has acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company, the Selling Stockholders or any other person, (ii) the Underwriter owes the Company and the Selling Stockholders only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriter may have interests that differ from those of the Company and the Selling Stockholders. Each of the Company and the Selling Stockholders waives to the full extent permitted by applicable law any claims it may have against the Underwriter arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

16. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

17. Submission to Jurisdiction. Each of the Selling Stockholders and the Company hereby submits to the non- exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. Each of the Selling Stockholders and the Company irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum. Each of the Selling Stockholders irrevocably appoints Law Debenture Corporate Services, Inc., as its authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agrees that service of process upon such agent, and written notice of said service to it by the person serving the same to the address provided in Section 22 hereof, shall be deemed in every respect effective service of process upon it in any such suit or proceeding. Each of the Company and the Selling Stockholders further agrees to take any and all action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of seven years from the date of this Agreement.

18. Judgment Currency. The obligations of the Company and the Selling Stockholders pursuant to this Agreement in respect of any sum due to the Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day, following receipt by the Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) the Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to the Underwriter hereunder, the Company and the Selling Stockholders agree, as a separate obligation and notwithstanding any such judgment, to indemnify the Underwriter against such loss.

19. Time. Time shall be of the essence of this Agreement. Except as otherwise set forth herein, specified times of day refer to New York City Time.

Agreement (as defined below)

Ladies and Gentlemen:

The undersigned understands that you propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with China Biologic Products, Inc., a Delaware corporation (the “Company”), and certain selling stockholders to be named therein (the “Selling Stockholders”, providing for the public offering (the “Public Offering”) by the underwriter to be named therein (the “Underwriter”) of certain shares (the “Shares”) of the common stock of the Company, par value of $0.0001 each (the “Common Stock”).

To induce the Underwriter that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Xxxxxx Xxxxxxx & Co. International plc, it will not, during the period commencing on the date hereof and ending 90 days after the date of the final prospectus (the “Restricted Period”) relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock (collectively, “Covered Securities”) or (2) 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 Covered Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Covered Securities, in cash or otherwise. The foregoing sentence shall not apply to (a) the exercise of options (“Options”) to purchase Common Stock, including options issued pursuant to the Company’s equity compensation plans described in its Annual Report on Form 10-K for the year ended December 31, 2015, provided that such Common Stock shall remain subject to the terms of this letter; (b) the receipt from the Company of Common Stock in connection with the vesting of restricted stock units or the disposition of Common Stock to the Company or in open market transactions in connection with the payment of taxes due in connection with any such vesting; (c) the disposition of Common Stock to the Company or in open market transactions upon the exercise of Options to cover tax withholding obligations in connection with such exercise; (d) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions, (e) transfers of Covered Securities as a bona fide gift, (f) transfers of Covered Securities to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (g) transfers of Covered Securities upon death by will or by intestacy to the undersigned’s immediate family, or (h) distributions of Covered Securities to limited partners or stockholders of the undersigned and if the undersigned is an investment fund or a wholly-owned subsidiary of an investment fund, transfers of the Covered Shares to any other investment funds managed by the same investment advisor or general partner of the undersigned or to any wholly-owned subsidiaries of any such fund; provided that in the case of any transfer or distribution pursuant to clause (e) through (h), (i) each donee, transferee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Covered Securities, shall be required or shall be voluntarily made during the Restricted Period, or (i) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that (i) such plan does not provide for the transfer of Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Restricted Period. In addition, the undersigned agrees that, without the prior written consent of Xxxxxx Xxxxxxx & Co. International plc, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any Covered Securities. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions. For purposes of this letter, the term “immediate family” shall mean any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, sibling, mother-in- law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, and shall include adoptive relationships.

The undersigned understands that the Company and the Underwriter are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is binding upon the undersigned’s heirs, successors and assigns.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Company, the Selling Stockholders and the Underwriter. This Agreement shall become null and void if the Underwriting Agreement (other than the provisions thereof which survive termination) is terminated in accordance with its terms prior to payment for and delivery of the Shares to be sold thereunder, in which case, the undersigned shall be released from any and all obligations under this Agreement.

This agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Very truly yours,
