no reason to believe that it or its subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or
appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Change. 
 (32) Investment Company Act. The Company is not required, and after giving effect to the issuance and sale of the offered Securities and the application of the net proceeds therefrom as described in the Private Placement Memorandum
under “Use of Proceeds,” will not be required, to register as an “investment company” under the Investment Company Act of 1940, as amended (the “1940 Act”). 
  

 10 








 (33) Passive Foreign Investment Company. The Company does not expect to be a
Passive Foreign Investment Company (“PFIC”) within the meaning of Section 1297(a) of the United States Internal Revenue Code of 1986, as amended and the regulations and published interpretations thereunder (the
“Code”), for the taxable year ending December 31, 2008, and has no plan or intention to conduct its business in a manner that would be reasonably expected to result in the Company becoming a PFIC in the future under current
laws and regulations. 
 (34) Registration Rights. There are no persons with registration rights or other similar
rights to have any securities registered by the Company under the 1933 Act, other than with respect to the registration of the resale of the Securities under the 1933 Act pursuant to the Registration Rights Agreement. 
 (35) Similar Offerings. Neither the Company nor to its knowledge any of its Affiliates has, directly or indirectly, solicited any
offer to buy, sold or offered to sell or otherwise negotiated in respect of, or will solicit any offer to buy, sell or offer to sell or otherwise negotiate in respect of, in the United States or to any United States citizen or resident, any security
which is or would be integrated with the sale of the Securities in a manner that would require the offered Securities to be registered under the 1933 Act. 
 (36) Rule 144A Eligibility. The Securities are eligible for resale pursuant to Rule 144A and will not be, at Closing
Time, of the same class as securities listed on a national securities exchange registered under Section 6 of the 1934 Act, or quoted in a U.S. automated interdealer quotation system. 
 (37) No General Solicitation. Subject to compliance by Merrill Lynch, Pierce, Fenner & Smith Incorporated, CRT Capital
Group LLC, Oppenheimer & Co. Inc. and Collins Stewart LLC (the “Placement Agents”) with their representations and warranties in the Private Placement Agency Agreement dated July 8, 2008 (“Placement Agency
Agreement”), none of the Company, to its knowledge, its Affiliates or any person acting on its or any of their behalf has engaged or will engage, in connection with the offering of the offered Securities, in any form of general solicitation
or general advertising within the meaning of Rule 502(c) under the 1933 Act. 
 (38) No Registration Required.
Subject to compliance by the Purchasers with the representations and warranties of the Purchasers and the procedures set forth in Section 6 hereof and the Placement Agents with their representations and warranties in the Placement Agency
Agreement, it is not necessary in connection with the offer, sale and delivery of the offered Securities to the Purchasers in the manner contemplated by this Agreement and the Private Placement Memorandum to register the Securities under the 1933
Act or, until the Registration Statement is declared effective by the Commission, to qualify the Indenture under the Trust Indenture Act of 1939, as amended (the “1939 Act”). 
 (39) ERISA Compliance. The Company and its subsidiaries and any “employee benefit plan” (as defined under the Employee
Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established, administered, contributed to or maintained by the Company, its subsidiaries or
their ERISA Affiliates (as defined below) for employees or former employees of the Company and its affiliates are in compliance in all material respects with ERISA, the Internal Revenue Code of 1986, as amended (the “Code”) and any
other applicable statutes, orders, rules and regulations to the extent applicable to the “employee benefit plans” of the Company. No prohibited transaction, within the meaning of Section 406 of ERISA or Section 4975 of the Code,
to the extent applicable to the Company, has occurred with respect to any such plan, excluding transactions effected pursuant to a statutory or administrative exemption; and for each such plan that is subject to the funding rules of Section 412
of the Code or Section 302 of ERISA, no “accumulated funding deficiency,” as defined in Section 412 of the Code, has been incurred, whether or not waived, and the fair market value of the assets of each such plan (excluding for
these purposes 

  

 11 








 
accrued but unpaid contributions) exceeds the present value of all benefits accrued under such plan determined using reasonable actuarial assumptions.
“ERISA Affiliate” means, with respect to the Company or its subsidiaries, any member of any group of organizations described in Section 414 of the Code, of which the Company or its subsidiaries is a member. No “reportable
event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee
benefit plan” subject to Title IV of ERISA established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit
liabilities” (as defined under ERISA). Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or
withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA
Affiliates that is intended to be qualified under Section 401 of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification. 
 (40) Regulatory Matters. Except as described in the Private Placement Memorandum, the Company and each of its subsidiaries:
(i) is and at all times has been in material compliance with all statutes, rules or regulations applicable to the ownership, testing, development, manufacture, packaging, processing, use, distribution, marketing, labeling, promotion, sale,
offer for sale, storage, import, export or disposal of any product manufactured or distributed by the Company or such subsidiary (“Applicable Laws”); (ii) has not received any notice of adverse finding, warning letter, untitled
letter or other correspondence or notice from the SFDA or any other Regulatory Agency alleging or asserting noncompliance with any Applicable Laws or any Governmental Licenses; (iii) has not received notice of any claim, action, suit,
proceeding, hearing, enforcement, investigation, arbitration or other action from any Regulatory Agency or third party alleging that any product operation or activity is in violation of any Applicable Laws or Government Licenses and has no knowledge
that any such Regulatory Agency or third party is considering any such claim, litigation, arbitration, action, suit, investigation or proceeding; (iv) has not received notice that any Regulatory Agency has taken, is taking or intends to take
action to materially limit, suspend, materially modify or revoke any Government Licenses and has no knowledge that any such Regulatory Agency is considering such action; and (v) has filed, obtained, maintained or submitted all material reports,
documents, forms, notices, applications, records, claims, submissions and supplements or amendments as required by any Applicable Laws or Government Licenses and that all such reports, documents, forms, notices, applications, records, claims,
submissions and supplements or amendments were complete and correct on the date filed in all material respects (or were corrected or supplemented by a subsequent submission). The statements in the Private Placement Memorandum, or incorporated by
reference into the Private Placement Memorandum from the Company’s Form 10-K for the period ended December 31, 2007, under the captions “Risk Factors—There could be changes in government regulations toward the pharmaceutical and
nutraceutical industries that may adversely affect our business,” “Risk Factors—Our business may be affected by unexpected changes in regulatory requirements in the jurisdictions in which we operate,” “Risk Factors—Our
international operations require us to comply with a number of U.S. and international regulations,” “Risk Factors—We may be unable to secure the government licenses that are necessary for us to engage in the sale of analgesic
pharmaceuticals,” “Risk Factors—Some of our TCM products and technologies potentially could be restricted from foreign ownership” and “Business—Regulation of Our Industry” (collectively, the “Regulatory
Sections”) fairly present in all material respects any Applicable Laws, and all pending or to the Company’s knowledge threatened legal or governmental proceedings relating to such Applicable Laws that are material to the Company’s
business in light of the applicable disclosure requirements under the 1934 Act. 
 (41) Public Officials. Neither
the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its 

  

 12 








 
subsidiaries is aware of or has taken any action directly or indirectly, that would result in a violation by such persons of the FCPA (as defined below),
including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift,
promise to give, or authorization of the giving of anything of value to any “Foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in
contravention of the FCPA and the Company and its subsidiaries have conducted their businesses in compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to
ensure, continued compliance therewith. “FCPA” means the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder. 
 (42) Money Laundering Laws. The operations of the Company and its subsidiaries have complied in all material respects with
applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all jurisdictions, the rules and regulations thereunder and any related or
similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency,
authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened. 
 (43) U.S. Sanctions. Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer
or employee of the Company or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Department of the Treasury. 
 (44) Enforceability. The Transaction Documents are in proper form under the laws of China for the enforcement thereof against the
Company in accordance with the laws of China and to ensure the legality, validity, enforceability or admissibility into evidence in China of the Transaction Documents; it is not necessary that the Transaction Documents, the Private Placement
Memorandum or any other document be filed or recorded with any court or other authority in China or that any Chinese stamp duty or similar tax be paid on or in respect of the Transaction Documents or any other document to be furnished thereunder.

 (45) Choice of Law. The choice of the law of the State of New York as the governing law of the Transaction
Documents is a valid choice of law under the laws of China and will be honored by courts in China, subject to compliance with relevant civil procedural requirements (which do not involve a reexamination of the merits of the claim) in China.

 (46) Immunity. Neither the Company or any subsidiary nor any of their respective properties, assets or revenues has
any right of immunity under Chinese, New York or U.S. federal law, from any legal action, suit or proceeding, from the giving of any relief in any such legal action, suit or proceeding, from setoff or counterclaim, from the jurisdiction of any
Chinese, New York or U.S. federal court, from service of process, attachment upon or prior to judgment, or attachment in aid of execution of judgment, or from execution of a judgment, or other legal process or proceeding for the giving of any relief
or for the enforcement of a judgment, in any such court, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with the Transaction Documents or the offered Securities; and, to the extent that the
Company, or any subsidiary or any of their respective properties, assets or revenues may have or may hereafter become entitled to any such right of immunity in any such court in which proceedings may at any time be commenced, each of the Company and
the subsidiaries waives or will waive such right to the extent permitted by law. 
  

 13 








 (47) Enforceability of Judgments. Any final judgment for a fixed sum of money
rendered by a New York Court having jurisdiction under New York law in respect of any suit, action or proceeding against the Company based upon the Transaction Documents would be recognized and enforced against the Company by Chinese courts without
reexamining the merits of the case under the common law doctrine of obligation; provided that (i) adequate service of process has been effected and the defendant has had a reasonable opportunity to be heard, (ii) such judgments or
the enforcement thereof are not contrary to the law, public policy, security or sovereignty of China, (iii) such judgments were not obtained by fraudulent means and do not conflict with any other valid judgment in the same matter between the
same parties, and (iv) an action between the same parties in the same matter is not pending in any Chinese court at the time the lawsuit is instituted in the foreign court. 
 (48) Solvency. As of the date hereof and immediately prior to, and immediately following, the issuance of the Securities, and
immediately after the application of the proceeds from the offering and sale of the Securities, the Company and each of its subsidiaries is, and will be, Solvent (as defined below); neither the Company nor any of its subsidiaries is contemplating
either the filing of a petition by it under any bankruptcy or insolvency laws or the liquidating of all or a substantial portion of its property, and neither the Company nor any of its subsidiaries has knowledge of any person contemplating the
filing of any such petition against the Company or any of its subsidiaries. As used herein, “Solvent” means, for any person on a particular date, that, on such date, (i) the fair value of the property of such person is greater than the
total amount of liabilities, including, without limitation, contingent liabilities, of such person, (ii) the present fair salable value of the assets of such person is not less than the amount that will be required to pay the probable liability of
such person on its debts as they become absolute and matured, (iii) such person does not intend to, and does not believe that it will, incur debts and liabilities beyond such person’s ability to pay as such debts and liabilities mature, (iv)
such person is not engaged in a business or a transaction, and is not about to engage in a business or a transaction, for which such person’s property would constitute unreasonably small capital and (v) such person is able to pay its debts as
they become due and payable. 
 (49) Registration. The Company satisfies (A) all conditions for the use of a
registration statement on Form S-3 under the 1933 Act, including without limitation, (i) the registrant requirements of General Instruction I.A of Form S-3 under the 1933 Act and the transaction requirements of General Instructions I.B.1 of Form S-3
under the 1933 Act and (ii) to register the Securities, and the Common Stock issuable upon conversion of the Securities, for resale in the manner contemplated by the Transaction Documents; and (B) the conditions set forth in Rules 415(a)(1)(i) and
430B(b) under the 1933 Act. 
 (50) Rule 144 Eligibility. The Company is subject to the reporting requirements of the
Exchange Act, has filed all required reports under Section 13 of the Exchange Act during the last 12 months and has filed current “Form 10 Information” (as that phrase is defined in Rule 144(i)(3) of the 1933 Act) with the SEC reflecting
its status as an entity that is no longer subject to Rule 144(i)(1)(i) of the 1933 Act, and accordingly restricted securities of the Company are currently eligible to be sold in accordance with Rule 144 of the 1933 Act. 
 (51) No Material Non-Public Information. The Company confirms that neither it nor its officers or directors or to its knowledge
any person acting on its behalf has provided any Purchaser or its respective agents or counsel (other than any Purchaser that has executed a confidentiality agreement with respect to such information) with any information that the Company believes
constitutes material, non-public information, except insofar as the existence and terms of the transactions contemplated herein may constitute such information. The Company understands and confirms that the Purchasers will rely on the foregoing
representations and covenants in effecting transactions in securities of the Company. 
 (b) Officer’s Certificates. Any certificate
signed by any officer of the Company or its subsidiaries delivered to Latham & Watkins LLP (the “Designated Investor’s Counsel”) shall be deemed a representation and warranty by the Company to each Purchaser as to the
matters covered thereby. 
  

 14 








 SECTION 2. Sale and Delivery to the Purchasers; Closing. 
 (a) Securities. On the basis of the representations, warranties and agreements herein contained and subject to the terms and conditions herein set
forth, the Company agrees to sell to each Purchaser, severally and not jointly, and each Purchaser, severally and not jointly, agrees to purchase from the Company, up to the aggregate principal amount of Securities set forth on such Purchaser’s
signature page hereto, at a price of 100% of the principal amount thereof. Each Purchaser acknowledges that, in accordance with the provisions of this Section 2, the Company may sell to the Purchaser, and the Purchaser will purchase, less than
all of the aggregate principal amount of Securities set forth on such Purchaser’s signature page hereto. 
 (b) Payment. The
completion of the purchase and sale of the Securities (the “Closing”) shall occur at the offices of the Company’s counsel, Loeb & Loeb LLP, on July 15, 2008, (the “Scheduled Closing Date”) at 10:00 a.m.
(Eastern time), unless the Closing is delayed by the Company pursuant to the following paragraph (the time at which the Closing occurs being the “Closing Time”). At the Closing, (1) the Company shall cause the Escrow Agent
to deliver to the Purchasers the Securities registered in the name of the applicable Purchasers, and (2) the aggregate purchase price for the Securities shall be delivered by the Escrow Agent on behalf of the Purchasers to the Company.

 The Closing shall occur at the Scheduled Closing Date (1) if the aggregate amount of funds deposited by the Purchasers with the
Escrow Agent is at least $115.0 million on such date and (2) the conditions set forth in Section 5 are satisfied. If the aggregate amount of funds deposited by the Purchasers with the Escrow Agent is less than $115.0 million on
the Scheduled Closing Date, the Company may delay the Closing until a date that is no later than July 21, 2008 (the “Delayed Closing Date”), at which time the Closing shall occur if, at such time, at least $115.0 million in
aggregate amount of funds shall have been deposited by the Purchasers with the Escrow Agent. If the Closing is delayed pursuant to the preceding sentence and the aggregate amount of funds deposited by the Purchasers with the Escrow Agent remains
less than $115.0 million on the Delayed Closing Date, the Company may terminate this Agreement on the Delayed Closing Date without liability on the part of the non-defaulting Purchasers or on the part of the Company, except for the Company’s
obligation to pay Purchaser’s fees and expenses in accordance with Section 4 hereof. Nothing contained herein shall relieve a defaulting Purchaser of any liability it may have to the Company or any non-defaulting Purchaser for damages
caused by its default. The aggregate principal amount of Securities that may be sold pursuant to this Agreement is $115.0 million. 
 If,
(1) on the Scheduled Closing Date or (2) on the Delayed Closing Date, any Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase, the Company and the non-defaulting Purchasers may in their discretion
arrange for the purchase of such Securities by any Purchaser on the terms contained in this Agreement, which purchase shall occur (i) if the Closing occurs on the Scheduled Closing Date, on the Scheduled Closing Date or at any time thereafter
until the Delayed Closing Date or (ii) if the Closing occurs on the Delayed Closing Date, on the Delayed Closing Date, or (iii) with respect to defaults that occur on the Delayed Closing Date, as soon as practicable after the Delayed
Closing Date. 
 If the Company accepts the Purchaser’s offer to buy Securities in whole or in part, the Company or its representatives
shall notify each Purchaser at the telephone number provided on such Purchaser’s signature page thereto of the precise amount of Securities that the Company shall sell to such Purchaser and such Purchaser shall buy. Payment by a Purchaser for
the Securities shall be made by wire transfer of immediately available funds to the Escrow Agent in accordance with instructions below. Upon receipt by the Escrow Agent of a joint notice as required under the terms of the Escrow Agreement (as
hereinafter defined) that the conditions to the Closing are satisfied, it shall deliver each Purchaser’s payment to the Company and the corresponding Securities to the DTC account specified in the Purchaser signature pages hereto. If such
conditions to the Closing are not satisfied as of the Delayed Closing Date, this Agreement shall terminate and, the Escrow Agent shall return each Purchaser’s funds to the applicable Purchaser promptly, but in any event not later than the
business day following the Delayed Closing Date. 
  

 15 








 Subject to the provisions of the second and third preceding paragraphs, the Company’s obligation to
issue and sell the Securities to the Purchasers shall be subject only to the accuracy of the representations and warranties made by the Purchasers and the fulfillment of those undertakings of the Purchasers to be fulfilled prior to the Closing. The
Purchasers’ respective obligations to purchase the accepted Securities shall be subject to the conditions set forth in Section 5 hereof. 
 Promptly after the Company notifies each Purchaser of the Securities that the Company shall sell to such Purchaser, but in any event no later than one business day prior to the Scheduled Closing Date, such Purchaser shall remit by wire
transfer the amount of funds equal to the aggregate purchase price for the Securities being purchased by such Purchaser to the following account designated by the Company pursuant to the terms of the Escrow Agreement (the “Escrow
Agreement”) a copy of which is attached hereto as Exhibit C relating to the offering of the Securities and entered into by and among the Company and the Escrow Agent: 
  

			
	 Bank Name: Wells Fargo Bank, N.A.
	  	
	 Bank ABA: 121000248
	  	
	 BNF Acct.: Corporate Trust Clearing Account

	 BNF A/C: 0001038377

                               American Oriental Bioengineering, Inc.

		
	 Attn: Angie Knoll
	  	
	 Tel. No.: (215) 861-9413
	  	

 Such funds shall be held in escrow until the Closing and delivered by the Escrow Agent on behalf
of the Purchasers to the Company upon the satisfaction of the conditions to the obligations of the Purchasers set forth in Section 5 hereof and the Escrow Agent’s receipt of the joint notice required for release of funds as specified in
this Section 2(b). 
 (c) Settlement. Prior to or promptly after the execution of this Agreement by the Purchasers and the Company,
each Purchaser shall direct the broker-dealer at which the account or accounts to be credited with its Securities are maintained (which broker/dealer shall be a DTC participant) to set up a Deposit Withdrawal at Custodian (“DWAC”)
instructing the Escrow Agent to credit such account or accounts with the Securities by means of an electronic book-entry delivery. Such DWAC shall indicate the settlement date for the deposit of the Securities, which date shall be provided to the
Purchasers. Simultaneously with the delivery to the Company by the Escrow Agent of the funds held in escrow described in Section 2(b), the Company shall direct the Escrow Agent to credit each Purchaser’s account or accounts with the
Securities pursuant to the information contained in the DWAC. 
 SECTION 3. Covenants of the Company. The Company covenants with
each Purchaser as follows: 
 (a) Qualification of Securities for Offer and Sale. The Company will use its reasonable best efforts, in
cooperation with the Purchasers, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions as the Purchasers may designate and to maintain such qualifications in effect as long as
required for the sale of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities business in any jurisdiction in
which it is not otherwise so subject in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing so. 
 (b) Restriction on Sale of Securities. Except as otherwise contemplated by the Private Placement Memorandum and the Transaction Documents, during a period of 90 days from the date of the Final Private Placement Memorandum (the
“Lock-up Period”), the Company shall not, without the prior written consent of each Purchaser that acquires $30.0 million or more in aggregate principal amount of Securities pursuant to this 

  

 16 








 
Agreement, directly or indirectly, (1) issue, sell, offer or agree to sell, grant any option for the sale of, or otherwise transfer or dispose of, any
other debt securities of the Company, or securities of the Company that are convertible into, or exchangeable for, the Securities or such other debt securities, (2) offer, pledge, announce the intention to sell, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, lend or otherwise transfer or dispose of any shares of Common Stock or securities convertible into or exchangeable or
exercisable for or repayable with Common Stock or (3) enter into any swap or other agreement or any transaction that transfers, in whole or in part, the economic consequences of ownership of the Common Stock, or any securities convertible into
or exchangeable or exercisable for or repayable with Common Stock, whether any such swap or transaction described in clause (2) or (3) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise;
provided, however, that the Company may offer, issue and sell shares of Common Stock or securities convertible into or exchangeable or exercisable for shares of Common Stock, or debt securities (i) pursuant to any employee, officer or director
stock or benefit plan disclosed in the Private Placement Memorandum, (ii) upon the conversion or exercise of the Securities or securities outstanding on the date hereof disclosed in the Private Placement Memorandum, (iii) issued or to be
issued by the Company in connection with an acquisition, provided that (A) in the case of an acquisition of a private company, the recipient of such shares or securities shall enter into a lock-up agreement for the balance of the Lock-up Period
and (B) in the case of an acquisition of a public company, such shares or securities shall not be issued until the expiration of the Lock-up Period. 
 (c) PORTAL Designation. The Company will use its reasonable best efforts to permit the Securities to be designated PORTAL securities in accordance with the rules and regulations adopted by the Financial
Industry Regulatory Authority (“FINRA”) relating to trading in The PORTAL Market.

Section 6 of the 1934 Act on which shares of its Common Stock are then listed. 
 (e) Reservation of Shares of Common Stock. The
Company shall reserve and keep available at all times, free of preemptive rights, shares of Common Stock for the purpose of enabling the Company to satisfy any obligations to issue shares of Common Stock upon conversion of the Securities.

 (f) DTC. The Company will use its reasonable best efforts to permit the Securities to be eligible for clearance and settlement
through the facilities of DTC and (ii) comply with all of its obligations set forth in the representations letter of the Company to DTC relating to approval of the securities by DTC for “book entry” transfer. 
 (g) Use of Proceeds. The Company will apply the net proceeds from the sale of the Securities to be sold by it hereunder for the purposes
set forth in the Private Placement Memorandum. 
 (h) Equal Treatment of Purchasers. No consideration shall be offered
or paid to any Purchaser to amend or consent to a waiver or modification of any provision of any of the Transaction Documents or in consideration of the exchange, redemption or repurchase of any Security unless the same consideration is also offered
to all of the Purchasers to the Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to
treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise. 
 (i) Press Release. By 9:30 a.m. (New York City time) on July 9, 2008, the Company shall issue a press release disclosing the transactions

 (3) Integration. The Company agrees that it will not and will cause its Affiliates not to, directly or indirectly, solicit any offer to buy, sell or make any offer or sale of, or otherwise negotiate in respect

 (5) Restriction on Resales. The Company will not, and will cause its Affiliates not to, resell any offered Securities which are
“restricted securities” (as such term is defined under Rule 144(a)(3) under the 1933 Act), whether as beneficial owner or otherwise (except as agent acting as a securities broker on behalf of and for the account of customers in the
ordinary course of business in unsolicited broker’s transactions) that have been reacquired by any of them and shall immediately upon any purchase of any such Securities submit such Securities to the Trustee for cancellation.

(if available), (C) pursuant to an effective registration statement under the 1933 Act or (D) to the Company or one of its subsidiaries, in each of cases (A) through (D) in accordance with any applicable securities laws of any
state of the United States, and (ii) the Purchaser will, and each subsequent holder of the Securities will be required to, notify any subsequent purchaser of the Securities or the Common Stock issued upon conversion of the Securities of the
resale restrictions referred to in clause (i) above and will provide the Company and the transfer agent such certificates and other information as they may reasonably require to confirm that the transfer by it complies with the foregoing
restrictions, if applicable. 
 (3) The Purchaser understands that the Securities and the Common Stock issuable upon
conversion of the Securities will, until the Securities can be sold to the public in accordance with Rule 144 under the 1933 Act, unless sold pursuant to a registration statement that has been declared effective under the 1933 Act or in
compliance with Rule 144, bear a legend substantially to the following effect:

examination, it has not relied on, and will not rely on, the Placement Agents, any statements or other information provided by the Placement Agents concerning the Company or the terms of this offering or any due diligence investigation that the

agreement and received such information or participated in such discussions as are satisfactory to it or has elected in its sole discretion not to request such information or discussions. 
 (6) The Purchaser, its affiliates and any of its and their directors, officers, employees, agents, advisors and controlling persons are
aware that the U.S. securities laws prohibit any person that has 

  

 21 








 
material non-public information about a company from purchasing or selling, directly or indirectly, securities of such company (including entering into
hedging transactions involving such securities) or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such other person is likely to purchase or sell securities. 
 (7) The Purchaser understands that the Company will rely upon the truth and accuracy of the foregoing representations, acknowledgements
and agreements and agrees that if any of the representations and acknowledgements deemed to have been made by it by its purchase of the Securities are no longer accurate, the Purchaser shall promptly notify the Company and each Placement Agent. The
Purchaser hereby consents to such reliance. If the Purchaser is acquiring the Securities as a fiduciary or agent for one or more investor accounts, it represents that it has sole investment discretion with respect to each such account and it has
full power to make the foregoing representations, acknowledgements and agreements on behalf of such account.

advisors and made its own assessments as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of Securities. 
 The Purchasers understand that the Company, and for purposes of the opinions to be delivered to it pursuant to Section 5 hereof, counsel to the Company will rely upon the accuracy and truth of the foregoing
representations, and the Purchasers hereby consent to such reliance.

other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”), as incurred, from and against any and all actions, causes of

of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (b) any

other certificate, instrument or document contemplated hereby, or thereby or (ii) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities. To the extent that the

intended to be for the sole and exclusive benefit of the Purchasers and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no 

  

 23 








 
other person, firm or corporation, except that the Placement Agents may rely on the representations, warranties and covenants of the Company and the
Purchasers set forth in Section 6 hereof. No purchaser of Securities from any Purchaser shall be deemed to be a successor by reason merely of such purchase.

unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. 
 SECTION 18. Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser,
and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser
pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with
respect to such obligations or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Purchasers are not acting in concert or as a group, and the Company will not assert any such claim, with respect to such
obligations or the transactions contemplated by the Transaction Documents. Each Purchaser confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each
Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Purchaser to
be joined as an additional party in any proceeding for such purpose.

 (a) the Designated Purchaser Representative shall be entitled to rely upon any order, judgment, certification, instruction, notice, opinion or other
writing delivered to it without being required to determine the 

  

 24 








 
authenticity or the correctness of any fact stated therein or the propriety or validity of service thereof, notwithstanding any such order or judgment being
subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction; 
 (b) the Designated
Purchaser Representative may act in reliance upon any instrument or signature believed by it to be genuine and may assume that any person purporting to give notice or receipt or advice or make any statement or execute any document in connection with
the provisions of the Escrow Agreement has been duly authorized to do so; 
 (c) in the event the Designated Purchaser Representative
reasonably believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Designated Purchaser Representative under the Escrow Agreement, the
Designated Purchaser Representative may, in its sole discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to any Purchaser or other person for refraining from taking such action, unless the
Designated Purchaser Representative received written instructions signed by the Purchaser that eliminates such ambiguity or uncertainty to the satisfaction of the Designated Purchaser Representative; 
 (d) the Designated Purchaser Representative shall not be liable for any error of judgment, or any action taken, suffered or omitted to be taken, under the
Escrow Agreement except in the case of its gross or willful misconduct, and no implied covenants or obligations shall be inferred from the Escrow Agreement against the Designated Purchase Representative.

 Capitalized terms which are undefined herein shall have the meaning ascribed to them in the Securities Purchase Agreement dated July 9, 2008 by and among
American Oriental Bioengineering, Inc. and the Purchasers signatory thereto. 
 (A) Each of the Chinese Subsidiaries has been duly
incorporated and is validly existing as a corporation in good standing under the laws of its jurisdiction of incorporation. 
 (B) Each
Chinese Subsidiary has full legal right, power and authority (corporate and other) to own, use, lease and operate its assets and to conduct its business in the manner presently conducted and as described in the Private Placement Memorandum and is
duly qualified to transact business in each jurisdiction in which it owns or uses or leases properties, conducts any business or in which such qualification is required. Except as disclosed in the Private Placement Memorandum, each Chinese

Chinese Subsidiary is in compliance with the provisions of all such licenses, consents, authorizations, approvals, orders, certificates or permits in all material respects. Following due inquiry, such counsel has no reason to believe that any
National Final Production Standard for the Company’s products, where application for such standard is currently pending, will not be granted or obtained, free from any condition or requirement compliance with which could reasonably be expected
to have a Material Adverse Effect on the Company or which the Company could not reasonably be expected to be able to satisfy. 
 (C) All of
the issued and outstanding shares of capital stock of each of the Chinese Subsidiaries have been duly and validly authorized and issued and are fully paid and nonassessable, and, to such counsel’s knowledge, the Company owns of record and
beneficially, free and clear of any security interests, claims, liens, proxies, equities or other encumbrances, all of the issued and outstanding shares of such stock. To such counsel’s knowledge, except as described in the Private Placement
Memorandum, there are no options, warrants, agreements, contracts or other rights in existence to purchase or acquire from the Chinese Subsidiaries any shares of the capital stock of the Chinese Subsidiaries. 
 (D) The application of the net proceeds to be received by the Company from the offering as contemplated by the Private Placement Memorandum, will not
contravene any provision of applicable Chinese law, rule or regulation, or the articles of association, other constitutive documents or the business license or other constitutive documents of any Chinese Subsidiary or contravene the terms or
provisions of, or constitute a default under, any material indenture, mortgage, deed of trust, loan agreement, note, lease or other agreement or instrument binding upon any Chinese Subsidiary, or any judgment, order or decree of any governmental
agency in China. 
  

 A-1 








 (E) To the best of such counsel’s knowledge, each Chinese Subsidiary has valid title to all of its
properties and assets, in each case, free and clear of all liens, charges, encumbrances, equities, claims, defects, options or restrictions; each lease agreement to which such Chinese Subsidiary is a party is legally executed; except as described in
the Private Placement Memorandum, the leasehold interests of each Chinese Subsidiary are fully protected by the terms of the lease agreements, which are valid, binding and enforceable in accordance with their respective terms under Chinese law; and,
to the best of such counsel’s knowledge, neither the Company nor any Chinese Subsidiary owns, operates, manages or has any other right or interest in any other material real property of any kind, except as described in the Private Placement
Memorandum. 
 (F) To the best of such counsel’s knowledge, there are no outstanding guarantees or contingent payment obligations of any
Chinese Subsidiary in respect of indebtedness of third parties except as disclosed in the Private Placement Memorandum. 
 (G) To the best of
such counsel’s knowledge, no Chinese Subsidiary or any of its subsidiaries is in breach or violation of or in default, as the case may be, under (1) its articles of association, business licenses or any other constituent documents,
(2) any material obligation, indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness governed by Chinese law, (3) any material obligation, license, lease, contract or other agreement or
instrument governed by Chinese law to which the Company or any of the subsidiaries is a party or by which any of them or any of their respective properties may be bound or affected, except for such breach or violation or default as would not
reasonably be expected to have a Material Adverse Effect, or (4) any law, regulation or rule of China, or any decree, judgment or order of any court in China, applicable to the Company or any of the subsidiaries (nor has any event occurred
which with notice, lapse of time, or both would result in any breach of, or constitute a default under or give the holder of any indebtedness (or a person acting on such holder’s behalf) the right to require the repurchase, redemption or
repayment of all or a part of such indebtedness). 
 (H) Each Chinese Subsidiary owns or otherwise has the legal right to use, or can acquire
on reasonable terms, trademarks, service marks and trade names currently employed by it in connection with the business currently operated by it; except as described in the Private Placement Memorandum, to the best of such counsel’s knowledge
after due inquiry, no Chinese Subsidiary has received any notice of infringement of or conflict with asserted rights of others with respect to any of the foregoing which, individually or in the aggregate, if the subject of an unfavorable decision,
ruling or finding, would result in any Material Adverse Effect; 
 (I) There are no legal, governmental, administrative or arbitrative
proceedings before any court of China or before or by any governmental agency pending or, to the best of such counsel’s knowledge, threatened against, or involving the properties or business of, the Company or any Chinese Subsidiary or to which
any of the properties of any Chinese Subsidiary is subject which will have a Material Adverse Effect. 
 (J) The execution, delivery and
performance of the Purchase Agreement and the consummation of the transactions herein contemplated (including the issuance or sale of the Securities by the Company and the obligation of the Company to issue Common Stock upon the conversion of the
Securities, except such as may be required under the Securities Act or state securities laws) will not: 
  

	 	(1)	 	result in a breach or violation of any of the terms and provisions of, or constitute a default under, any agreement or instrument known to such counsel which is governed by the laws
of China and to which any of the Chinese Subsidiaries are a party; or 

  

	 	(2)	 	require any consent, approval, authorization or order of, or filing with, any court or governmental agency or body under any Chinese statute, rule or regulation applicable to any
Chinese Subsidiary on or prior to the date hereof that have not been obtained or made. 

 (K) Such counsel has advised the
Company as to the content of the SAFE Rules and Regulations, in particular the relevant provisions thereof that purport to require offshore special purpose vehicles formed for the 

  

 A-2 








 
purpose of obtaining a stock exchange listing outside of China and controlled directly or indirectly by Chinese companies or natural persons, to obtain the
approval of the Chinese Securities Regulatory Commission prior to the listing and trading of their securities on stock exchange located outside of China. The issuance and sale of the Securities, the listing and trading of the Common Stock on the
NYSE or the consummation of the transactions contemplated by the Purchase Agreement is not and will not be affected by the SAFE Rules and Regulations or any SAFE Rule and Related Clarifications. As of the date hereof, the SAFE Rules and Related
Clarifications did not and do not require the Company to obtain the approval of the Chinese Securities Regulatory Commission prior to the issuance and sale of the Securities, the listing and trading of the Common Stock on the NYSE or the
consummation of the transactions contemplated by the Purchase Agreement. 
 (L) Under Chinese law, there are no reporting obligations on
non-Chinese holders of the Securities. 
 (M) As a matter of Chinese law, no holder of the Securities who is not a Chinese resident will be
subject to any personal liability, or be subject to a requirement to be licensed or otherwise qualified to do business or be deemed domiciled or resident in China, by virtue only of holding such Securities. There are no limitations under Chinese law
on the rights of holders of the Securities who are not Chinese residents to hold, vote or transfer their securities nor any statutory preemptive rights or transfer restrictions applicable to the Securities. 
 (N) The descriptions in the Private Placement Memorandum of Chinese statutes, regulations, legal and governmental proceedings, contracts and other
documents are accurate and fairly present the information required to be shown; and such counsel does not know of any statutes, regulations, legal or governmental proceedings or contracts or other documents that would be required to be described in
a registration statement under the Securities Act if the offering contemplated in the Agreement was made to the public (or required to be filed under the Exchange Act if upon such filing they would be incorporated in whole or in part in such
registration statement by reference therein). 
 (O) To the best of such counsel’s knowledge after due inquiry, none of the Chinese
Subsidiaries possesses any registered intellectual property except as described in the Private Placement Memorandum, and each of the Chinese Subsidiaries possesses valid licenses in full force and effect or otherwise has the legal right to use, or
can acquire on reasonable terms, all material patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures),
trademarks, service marks and trade names currently employed by them in the ordinary course of business, and to the best of such counsel’s knowledge, none of the Chinese Subsidiaries has received any notice of infringement of or conflict with
asserted rights of others with respect to any of the foregoing. 
 (P) The submission of the Company to the non-exclusive jurisdiction of the
New York Courts, the waiver by the Company of any objection to the venue of a proceeding in a New York Court, the waiver and agreement of the Company not to plead an inconvenient forum, and the agreement of the Company that the Purchase Agreement be
construed in accordance with and governed by the law of the State of New York will be recognized by Chinese courts; service of process effected in the manner set forth in the Purchase Agreement will be effective to confer jurisdiction over the
subsidiaries, assets and property of the Company in China, subject to compliance with relevant civil procedural requirements (which do not involve a re-examination of the merits of the claim) in China; and any judgment obtained in a New York Court
arising out of or in relation to the obligations of the Company under the Purchase Agreement will be recognized by Chinese courts, subject to compliance with relevant civil procedural requirements (which do not involve a re-examination of the merits
of the claim) in China. 
 (Q) The indemnification and contribution provisions set forth in the Purchase Agreement do not contravene the
public policy or law of China, and insofar as matters of Chinese law are concerned, constitute the legal, valid and binding obligations of the Company, enforceable in accordance with the terms therein, subject, as 

  

 A-3 








 
to enforcement, to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights; the
Purchase Agreement is in proper legal form under Chinese law for the enforcement thereof against the Company, subject to compliance with relevant civil procedural requirements; and to ensure the legality, validity, enforceability or admissibility in
evidence of the Purchase Agreement, it is not necessary that any such document be filed or recorded with any court or other authority in China or that any stamp or similar tax be paid on or in respect of any such document. 
 (R) No stamp or other issuance or transfer taxes or duties and no capital gains, income, withholding or other taxes are payable by or on behalf of the
Company, any of the Chinese Subsidiaries, or any Purchaser to the Chinese government or any political subdivision or taxing authority thereof or therein in connection with (1) the creation, issuance, sale and delivery of the Securities,
(2) the sale and delivery by the Company of the Securities to or for the accounts of any Purchaser in the manner contemplated in the Purchase Agreement, (3) the execution, delivery and performance of the Purchase Agreement by the Company,
or (4) the sale and delivery by the Purchasers of the Securities in the manner contemplated in the Private Placement Memorandum. 
 (S)
The entry into, and performance or enforcement of the Purchase Agreement in accordance with its terms will not subject any Purchaser to any requirement to be licensed or otherwise qualified to do business in China, nor will any Purchaser be deemed
to be resident, domiciled, carrying on business through an establishment or place in China or in breach of any laws or regulations in China by reason of entry into, performance or enforcement of the Purchase Agreement. 
 (T) Under the laws of China, none of the Company or the Chinese Subsidiaries, or any of their respective properties, assets or revenues, is entitled to
any right of immunity on the grounds of sovereignty or otherwise from any legal action, suit or proceeding, set-off or counterclaim, the jurisdiction of any court in China, service of process, attachment prior to or in aid of execution of judgment,
or other legal process or proceeding for the granting of any relief or the enforcement of any judgment. 
 (U) To the best of such
counsel’s knowledge following due inquiry, each of the Company and the Chinese Subsidiaries is currently in compliance with all applicable Chinese laws and regulations, and the issuance, sale and delivery of the Securities by the Company as
described in the Private Placement Memorandum will not conflict with or result in a breach or violation of, the provisions of any applicable Chinese laws and the regulations.
