(i) Within fifteen Trading Days following the Closing, the Make Good Pledgor shall deliver, or cause to be delivered, to the Escrow Agent certificates evidencing an aggregate of 2,000,000 shares of the Company’s Common Stock, as
equitably adjusted for any stock splits, stock combinations, stock dividends or similar transactions (the "Escrow Shares"), along with stock powers executed in blank (or such other signed instrument of transfer acceptable to the

(iii) In furtherance thereof, the Company will (x) place a stop order on all Escrow Shares which shall expire on the date the Escrow Shares are delivered to the Investors or returned to the Make Good Pledgor, (y) notify the Transfer Agent in writing
of the stop order and the restrictions on such Escrow Shares under this Make Good Agreement and direct the Transfer Agent not to process any attempts by the Make Good Pledgor to resell or transfer any Escrow Shares before the date the Escrow Shares
that should be delivered to the Investors are delivered to the Investors or returned to the Make Good Pledgor, or otherwise in violation of this Make Good Agreement.  The Company shall notify the Investors as soon as the 2010 Make Good Shares and
2011 Make Good Shares have been deposited with the Escrow Agent.

2 

(iv) If within fifteen (15) trading days following the Closing, the Make Good Pledgor shall not have deposited all Escrow Shares into escrow in accordance with this Make
Good Agreement along with stock powers executed in blank (or such other signed instrument of transfer acceptable to the Company’s transfer agent), then, the Investor Agent shall have the right, at its sole discretion and selection, to either
(i) cash damages, as liquidated damages and not as a penalty, equal to [0.1% of the aggregate value of the Escrow Shares calculated by the closing price of the Company’s Common Stock on the fifth day following the Closing] on a daily basis
during the period between the sixth day following the Closing and the date on which the Escrow Shares are actually deposited into escrow; or (ii) issue a written demand to the Company, upon which the Company shall promptly, and in any event within
thirty (30) days from the date of such written demand, pay to Investors as listed on the written demand, as liquidated damages, an amount equal to those listed Investors’ entire Investment Amount without interest thereon. As a condition to the
receipt of such payment, such Investors shall return to the Company for cancellation of the certificates evidencing the Shares acquired by such Investors under this Agreement.

which, in any way, directly or indirectly, arises out of or relates to this Make Good Agreement or the obligations of the Make Good Pledgor hereunder. 

3. Representations and Undertakings of Make Good Pledgor and the Company and the Guarantors. The Make Good Pledgor (as to itself and the Escrowed Shares) and the Company (as to itself) and each Guarantor (as to itself and the Make Good
Pledgor), severally but not jointly, hereby represent and warrant to the Investors as follows: (i) All of the Escrow Shares are validly issued, fully paid and nonassessable shares of the Company, and free and clear of all pledges, liens and
encumbrances ("Lien"). Upon any transfer of Escrow Shares to Investors hereunder, Investors will receive full right, title and authority to such shares as holders of Common Stock of the Company free and clear of all Liens other than those
imposed by US Federal Securities laws.

(ii) The issuance of the Escrow Shares to the Make Good Pledgor, the Make Good Pledgor’s holding of the Escrow Shares and Mr. Zhao’s Option under the Option Agreement do not and will not violate or conflict with any applicable
laws and regulations, including but not limited to laws and regulations with regard to foreign exchanges, and any necessary filing and amendments thereto have been made on a timely basis. 

(iii) Performance of this Make Good Agreement and compliance with the provisions hereof will not violate any provision of any applicable law and will not conflict with or result in any breach of any of the terms, conditions or provisions of, or
constitute a default under, or result in the creation or imposition of any Lien upon any of the properties or assets of Make Good Pledgor pursuant to the terms of the Option Agreement, or any indenture, mortgage, deed of trust or other agreement or
instrument binding upon Make Good Pledgor or such properties or assets,
other than such breaches, defaults or Liens which would not have a material
adverse effect taken as a whole. 

3 

(iv) The Make Good Pledgor has carefully considered and
understands its obligations and rights under this Make Good Agreement, and in
furtherance thereof (x) has consulted with its legal and other advisors with
respect thereto and (y) hereby forever waives and agrees that it may not assert
any equitable defenses in any Proceeding involving the Escrow Shares. 

(v) Ms. Zhao is the sole shareholder of the Make Good Pledgor.
Ms. Zhao represents that Ms. Dan Li, being the sole director of the Make Good
Pledgor, has the full right, power and authorization to sign on this Make Good
Agreement on behalf of the Make Good Pledgor.

(vi) Each Guarantor undertakes to the Investors that prior to
the delivery and disbursement of the 2011 Make Good Shares in accordance with
the Section 4 hereof, there will not be any change in the shareholding structure
or directorship of the Make Good Pledgor, whether due to Mr. Zhao’s exercise of
his Option or not, unless the Investor Agent’s prior consent is obtained. 

4. Disbursement of Escrow Shares. 

a. The Make Good Pledgor agrees that in the event that the
After Tax Net Income (as defined below) reported in the Annual Report of the
Company for the fiscal year ending December 31, 2010, as filed with the
Commission on Form 10-K (or such other form appropriate for such purpose as
promulgated by the Commission) (the “2010 Annual Report”) is less than
$8,000,000 (the “2010 Guaranteed ATNI”), the Escrow Agent (on behalf of
the Make Good Pledgor) will transfer the 2010 Make Good Shares to the Investors
on a pro rata basis (determined by dividing each Investor’s Investment Amount by
the aggregate of all Investment Amounts delivered to the Company by the
Investors under the Securities Purchase Agreement) as specified in Exhibit
A to this Agreement for no consideration other than payment of their
respective Investment Amount paid to the Company at Closing and without any need
for action or notice by or on behalf of any Investor. The “2010 Make Good
Shares” means the number of shares of Common Stock calculated using the
following formula, as equitably adjusted for any stock splits, stock
combinations, stock dividends or similar transactions: 

“2010 Make Good Shares” = [(2010
Guaranteed ATNI – 2010 Audited ATNI)/$8,000,000] * 50% of the Escrow Shares”

In the event that the After Tax Net Income reported in the 2011
Annual Report is less than $12,000,000 (the “2011 Guaranteed ATNI”), the
Escrow Agent (on behalf of the Make Good Pledgor) will transfer the 2011 Make
Good Shares to the Investors on a pro rata basis (determined by dividing each
Investor’s Investment Amount by the aggregate of all Investment Amounts
delivered to the Company by the Investors under the Securities Purchase
Agreement) as specified in Exhibit A to this Agreement for no
consideration other than payment of their respective Investment Amount paid to
the Company at Closing and without any need for action or notice by or on behalf
of any Investor. The “2011 Make Good Shares” means the number of shares
of Common Stock calculated using the following formula, as equitably
adjusted for any stock splits, stock combinations, stock dividends or similar
transactions:

4 

“2011 Make Good Shares” = [(2011
Guaranteed ATNI – 2011 Audited ATNI)/$12,000,000] * 50% of the Escrow Shares”
For purposes hereof, “After Tax Net Income” shall mean the Company’s net
income after taxes for the fiscal year ending December 31, 2010 or December 31,
2011 (as applicable) in each case determined in accordance with GAAP as reported
in the 2010 Annual Report or 2011 Annual Report (as applicable).

If prior to the second anniversary of the filing of either of
the 2010 Annual Report or 2011 Annual Report (as applicable), the Company or
their auditors report or recognize that the financial statements contained in
such report are subject to amendment or restatement such that the Company would
recognize or report adjusted After Tax Net Income of less than either of the
2010 Guarantee ATNI or the 2011 Guaranteed ATNI (as applicable), then
notwithstanding any prior return of 2010 Make Good Shares and 2011 Make Good
Shares to the Make Good Pledgor, the Make Good Pledgor will, within 10 Business
Days following the earlier of the filing of such amendment or restatement or
recognition, deliver the relevant 2010 Make Good Shares and 2011 Make Good
Shares to the Investors without any further action on the part of the
Investors.

In the event that the 2010 Audited ATNI is equal to or greater
than the 2010 Guaranteed ATNI, no transfer of the 2010 Make Good Shares shall be
required by the Make Good Pledgor to the Investors under this Section 4 and
fifty percent (50%) of the Escrow Shares shall be promptly returned to the Make
Good Pledgor without the need of any approval or consent thereto by any
Investor. The remaining fifty percent (50%) of the Escrow Shares shall continue
to be held in escrow by the Escrow Agent and shall remain subject to this
Section 4. In the event that the 2011 Audited ATNI is equal to or greater than
the 2011 Guaranteed ATNI, no transfer of the 2011 Make Good Shares shall be
required by the Make Good Pledgor to the Investors under this Section and the
remaining fifty percent (50%) of the Escrow Shares shall be promptly returned to
the Make Good Pledgor without the need of any approval or consent thereto by any
Investor.

Any transfer of the 2010 Make Good Shares and 2011 Make Good
Shares under this Section shall be made to the Investors or the Make Good
Pledgor, as applicable, within 10 Business Days after the date which the 2010
Annual Report or 2011 Annual Report, as applicable, is filed with the Commission
and otherwise in accordance with this Make Good Agreement subject to return as
provided in the immediately preceding paragraph and, in the event that any of
the 2010 Make Good Shares and 2011 Make Good Shares are required to be
distributed to the Investors in accordance with the terms of this Agreement, the
Company has agreed that the Investor Agent will provide prompt written
instruction to the Escrow Agent with regard to the distribution of the 2010 Make
Good Shares and 2011 Make Good Shares, as the case may be, in an amount to each
Investor as set forth on Exhibit A attached hereto. The Investor Agent will
deliver to the Escrow Agent (with a copy to the Company) a copy of the 2010
Annual Report and 2011 Annual Report. Escrow Agent need only rely on such
letters from Investor Agent and will disregard any contrary or further calculations or instructions
in such regard delivered by or on behalf of the Company.

5 

Each of the Investors understands and agrees that such
Investor’s right to receive 2010 Make Good Shares or 2011 Make Good Shares, as
the case may be, is a unique and personal right of such Investor which requires
such Investor to continue to own the shares when the 2010 Audited ATNI or 2011
Audited ATNI, as the case may be, is determined for purposes of this Make Good
Agreement. The right of an Investor to receive any Make Good Shares will be
proportionately reduced if such Make Good Beneficiary does not continue to own
the same number of shares on the 2010 Audited ATNI determination date or the
2011 Audited ATNI determination date as are owned on the date hereof.
Furthermore, the right to receive Make Good Shares shall not run to the benefit
of any transferee of any Shares transferred by any Investor to a third party
(other than an entity affiliated with such Investors, family member or heir of
an Investors or to a trust or similar vehicle established by an Investor in
connection with estate planning purposes). 

b. Pursuant to Section 4(a), if the Investor Agent delivers a
notice to the Escrow Agent that the Escrow Shares are to be transferred to the
Investors, then the Escrow Agent shall immediately forward either the 2010 Make
Good Shares and 2011 Make Good Shares, as the case may be, to the Company’s
Transfer Agent for reissuance to the Investors in an amount to each Investor as
set forth on Exhibit A attached hereto and otherwise in accordance with
this Make Good Agreement. The Company covenants and agrees that upon any
transfer of 2010 Make Good Shares and 2011 Make Good Shares to the Investors in
accordance with this Make Good Agreement, the Company shall promptly instruct
its Transfer Agent to reissue such 2010 Make Good Shares and 2011 Make Good
Shares in the applicable Investor’s name and deliver the same, or cause the same
to be delivered as directed by such Investor in an amount to each Investor as
set forth on Exhibit A attached hereto. If the Company does not promptly
provide such instructions to the Transfer Agent of the Company, then the
Investor Agent is hereby irrevocably authorized and directed by the Company to
give such re-issuance instruction to the Transfer Agent of the Company. If a
notice from the Investor Agent pursuant to Section 4(a) indicates that the
Escrow Shares are to be returned to the Make Good Pledgor, then the Escrow Agent
will promptly deliver either the 2010 Make Good Shares, 2011 Make Good Shares or
any remaining proportion of the Escrow Shares after the transfer of 2010 Make
Good Shares and/or 2011 Make Good Shares to Investors, as the case may be, to
the Make Good Pledgor in accordance with instructions provided by the Make Good
Pledgor at such time. 

c. The Company and Make Good Pledgor covenant and agree to
provide the Escrow Agent with certified tax identification numbers by furnishing
appropriate forms W-9 or W-8 and such other forms and documents that the Escrow
Agent may request, including appropriate W-9 or W-8 forms for each Investor. The
Company and Make Good Pledgor understand that if such tax reporting
documentation is not provided and certified to the Escrow Agent, the Escrow
Agent may be required by the Internal Revenue Code of 1986, as amended, and the
Regulations promulgated thereunder, to withhold a portion of any interest or
other income earned on the investment of the Escrow Property.

5. Notice of Filings. The Company agrees to promptly provide the Investors with written notice of the filing with the Commission of any financial statements or reports referenced herein. 

6. Escrow Shares. If any Escrow Shares are deliverable to the Investors in accordance with this Make Good Agreement, (i) Make Good Pledgor covenants and agrees to execute all such instruments of transfer (including stock powers and assignment
documents) as are customarily executed to evidence and consummate the transfer of the Escrow Shares from Make Good Pledgor to the Investors, to the extent not done so in accordance with Section 2, and (ii) following its receipt of the documents
referenced in Section 6(i), the Company and Escrow Agent covenant and agree to cooperate with the Transfer Agent so that the Transfer Agent may promptly reissue such Escrow Shares in the applicable Investor’s name and delivers the same as
provided herein or otherwise directed in writing by the applicable Investors. Until such time as (if at all) the Escrow Shares are required to be delivered pursuant to the Securities Purchase Agreement and in accordance with this Make Good
Agreement, (i) any dividends payable in respect of the Escrow Shares and all voting rights applicable to the Escrow Shares shall be retained by Make Good Pledgor and (ii) should the Escrow Agent receive dividends or voting materials, such items
shall not be held by the Escrow Agent, but shall be passed immediately on to the Make Good Pledgor and shall not be invested or held for any time longer than is needed to effectively re-route such items to the Make Good Pledgor. In the event that
the Escrow Agent receives a communication requiring the conversion of the Escrow Shares to cash or the exchange of the Escrow Shares for that of an acquiring company, the Escrow Agent shall solicit and follow the written instructions of the Make
Good Pledgor; provided, that the cash or exchanged shares are instructed to be redeposited into the Escrow Account. Make Good Pledgor shall be responsible for all taxes resulting from any such conversion or exchange. 

Assuming the Make Good Pledgor provides good and valid title to the Escrow Shares to be transferred and delivered on behalf of the Make Good Pledgor to the Investors hereunder, free and clear of all liens, encumbrances, equities or claims, the
Escrow Agent will ensure that upon delivery of the Escrow Shares, good and valid title to the Escrow Shares, free and clear of all liens, encumbrances, equities or claims will pass to the Investors. The Escrow Agent shall not take any action which
could impair Investors’ rights in the Escrow Shares.  The Escrow Agent shall not sell, transfer, assign or otherwise dispose of (by operation of law or otherwise) or grant any option with respect to any Escrow Shares prior to the termination
of this Agreement. 

7. Interpleader. Should any controversy arise among the parties hereto with respect to this Make Good Agreement or with respect to the right to receive the Escrow Shares, Escrow Agent and/or the Investor Agent shall have the right to consult
and hire counsel and/or to institute an appropriate interpleader action to determine the rights of the parties. Escrow Agent and/or the Investor Agent are also each hereby authorized to institute an appropriate interpleader action upon receipt of a
written letter of direction executed by the parties so directing either Escrow Agent or the Investor Agent. If Escrow Agent or the Investor Agent is directed to institute an appropriate interpleader action, it shall institute such action not prior
to thirty (30) days after receipt of such letter of direction and not later than sixty (60) days after such date. Any interpleader
action instituted in accordance with this Section 7 shall be filed in any court
of competent jurisdiction in the State of New York, and the Escrow Shares in
dispute shall be deposited with the court and in such event Escrow Agent and the
Investor Agent shall be relieved of and discharged from any and all obligations
and liabilities under and pursuant to this Make Good Agreement with respect to
the Escrow Shares and any other obligations hereunder. 

7 

8. Exculpation and Indemnification of Escrow Agent
and the Investor Agent. 

a. Escrow Agent is not a party to, and is not bound by
or charged with notice of any agreement out of which this escrow may arise.
Escrow Agent acts under this Make Good Agreement as a depositary only and is not
responsible or liable in any manner whatsoever for the sufficiency, correctness,
genuineness or validity of the subject matter of the escrow, or any part
thereof, or for the form or execution of any notice given by any other party
hereunder, or for the identity or authority of any person executing any such
notice. Escrow Agent will have no duties or responsibilities other than those
expressly set forth herein. Escrow Agent will be under no liability to anyone by
reason of any failure on the part of any party hereto (other than Escrow Agent)
or any maker, endorser or other signatory of any document to perform such
person's or entity's obligations hereunder or under any such document. Except
for this Make Good Agreement and instructions to Escrow Agent pursuant to the
terms of this Make Good Agreement, Escrow Agent will not be obligated to
recognize any agreement between or among any or all of the persons or entities
referred to herein, notwithstanding its knowledge thereof. The Investor Agent’s
sole obligation under this Make Good Agreement is to provide written instruction
to Escrow Agent (following such time as the Company files certain periodic
financial reports as specified in Section 4 hereof) directing the distribution
of the Escrow Shares. The Investor Agent will provide such written instructions
upon review of the relevant After Tax Net Income reported in such periodic
financial reports as specified in Section 4 hereof or receipt of notice from the
Company under Section 4. The Investor Agent is not charged with any obligation
to conduct any investigation into the financial reports or make any other
investigation related thereto. In the event of any actual or alleged mistake or
fraud of the Company, its auditors or any other person (other than the Investor
Agent) in connection with such financial reports of the Company, the Investor
Agent shall have no obligation or liability to any party hereunder. 

b. Neither the Escrow Agent nor Investor Agent will be
liable for any action taken or omitted by it, or any action suffered by it to be
taken or omitted, absent gross negligence or willful misconduct. The Escrow
Agent and Investor Agent may each rely conclusively on, and will be protected in
acting upon, any order, notice, demand, certificate, or opinion or advice of
counsel (including counsel chosen by Escrow Agent or Investor Agent, as
applicable), statement, instrument, report or other paper or document (not only
as to its due execution and the validity and effectiveness of its provisions,
but also as to the truth and acceptability of any information therein contained)
which is reasonably believed by Escrow Agent or Investor Agent, as applicable,
to be genuine and to be signed or presented by the proper person or persons. The
duties and responsibilities of the Escrow Agent and Investor Agent, as the case
may be, hereunder shall be determined solely by the express provisions of this Make Good
Agreement and no other or further duties or responsibilities shall be implied,
including, but not limited to, any obligation under or imposed by any laws of
the State of New York upon fiduciaries. NEITHER THE ESCROW AGENT NOR INVESTOR
AGENT SHALL BE LIABLE, DIRECTLY OR INDIRECTLY, FOR ANY (I) DAMAGES, LOSSES OR
EXPENSES ARISING OUT OF THE SERVICES PROVIDED HEREUNDER, OTHER THAN DAMAGES,
LOSSES OR EXPENSES WHICH HAVE BEEN FINALLY ADJUDICATED TO HAVE DIRECTLY RESULTED
FROM THE ESCROW AGENT’S OR INVESTOR AGENT'S, AS THE CASE MAY BE, GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT, OR (II) SPECIAL, INDIRECT OR CONSEQUENTIAL
DAMAGES OR LOSSES OF ANY KIND WHATSOEVER (INCLUDING, WITHOUT LIMITATION, LOST
PROFITS), EVEN IF THE ESCROW AGENT OR INVESTOR AGENT, AS APPLICABLE, HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES OR DAMAGES AND REGARDLESS OF THE FORM
OF ACTION. 

8 

c. The Company and Make Good Pledgor each hereby, jointly and
severally, indemnify and hold harmless each of Escrow Agent, the Investor Agent
and any of their principals, partners, agents, employees and affiliates
from and against any expenses, including reasonable attorneys' fees and
disbursements, damages or losses suffered by Escrow Agent or the Investor Agent
in connection with any claim or demand, which, in any way, directly or
indirectly, arises out of or relates to this Make Good Agreement or the services
of Escrow Agent or the Investor Agent hereunder; except, that if Escrow Agent or
the Investor Agent is guilty of willful misconduct or gross negligence under
this Make Good Agreement, then Escrow Agent or the Investor Agent, as the case
may be, will bear all losses, damages and expenses arising as a result of its
own willful misconduct or gross negligence. Promptly after the receipt by Escrow
Agent or the Investor Agent of notice of any such demand or claim or the
commencement of any action, suit or proceeding relating to such demand or claim,
Escrow Agent or the Investor Agent, as the case may be, will notify the other
parties hereto in writing. For the purposes hereof, the terms "expense" and
"loss" will include all amounts paid or payable to satisfy any such claim or
demand, or in settlement of any such claim, demand, action, suit or proceeding
settled with the express written consent of the parties hereto, and all costs
and expenses, including, but not limited to, reasonable attorneys' fees and
disbursements, paid or incurred in investigating or defending against any such
claim, demand, action, suit or proceeding. The provisions of this Section 8
shall survive the termination of this Make Good Agreement, and the resignation
or removal of the Escrow Agent. 

9. Compensation of Escrow Agent. Escrow Agent shall be
entitled to compensation for its services as stated in the fee schedule attached
hereto as Exhibit B, which compensation shall be paid by the Company. The
fee agreed upon for the services rendered hereunder is intended as full
compensation for Escrow Agent's services as contemplated by this Make Good
Agreement; provided, however, that in the event that Escrow Agent
renders any material service not contemplated in this Make Good Agreement, or
there is any assignment of interest in the subject matter of this Make Good
Agreement, or any material modification hereof, or if any material controversy
arises
hereunder, or Escrow Agent is made a party to any litigation pertaining to this Make Good Agreement, or the subject matter hereof, then Escrow Agent shall be reasonably compensated by the Company for such extraordinary services and reimbursed for
all costs and expenses, including reasonable attorney's fees, occasioned by any delay, controversy, litigation or event, and the same shall be recoverable from the Company. Prior to incurring any costs and/or expenses in connection with the
foregoing sentence, Escrow Agent shall be required to provide written notice to the Company of such costs and/or expenses and the relevancy thereof and Escrow Agent shall not be permitted to incur any such costs and/or expenses which are not related
to litigation prior to receiving written approval from the Company, which approval shall not be unreasonably withheld. 

 10. Resignation of Escrow Agent. At any time, upon ten (10) Business Days' written notice to the Company and the Investors,
Escrow Agent may resign and be discharged from its duties as Escrow Agent hereunder. As soon as practicable after its resignation, Escrow Agent will promptly turn over to a successor escrow agent appointed by the Company the Escrow Shares held
hereunder upon presentation of a document appointing the new escrow agent and evidencing its acceptance thereof. If, by the end of the 10-Business Day period following the giving of notice of resignation by Escrow Agent, the Company shall have
failed to appoint a successor escrow agent, Escrow Agent shall deposit the Escrow Shares as directed by the Investor Agent with the understanding that such Escrow Shares will continue to be subject to the provisions of this Make Good Agreement. 

9 

11. Records. Escrow Agent shall maintain accurate records of all transactions hereunder. Promptly after the termination of this Make Good Agreement or as may reasonably be requested by the parties hereto from time to time before such
termination, Escrow Agent shall provide the parties hereto, as the case may be, with a complete copy of such records, certified by Escrow Agent to be a complete and accurate account of all such transactions. The authorized representatives of each of
the parties hereto shall have access to such books and records at all reasonable times during normal business hours upon reasonable notice to Escrow Agent and at the requesting party’s expense.

12. Notice. All notices, communications and instructions required or desired to be given under this Make Good Agreement must be in writing and shall be deemed to be duly given if sent by registered or certified mail, return receipt requested,
or overnight courier, to the addresses listed on the signature pages hereto. 

13. Execution in Counterparts.  This Make Good Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

14. Assignment and Modification.  This Make Good Agreement and the rights and obligations hereunder of the Company may be assigned by the Company only following the prior written consent of Investor Agent. This Make Good Agreement and the
rights and obligations hereunder of the Escrow Agent may be assigned by the Escrow Agent only with the prior consent of the Company and the Investor Agent. This Make Good Agreement and the rights and obligations hereunder of the Make Good Pledgor
may not be assigned by the Make Good Pledgor. Subject to the requirements under federal and
state securities laws, an Investor may assign its rights under this Make Good Agreement without any consent from any other party. This Make Good Agreement may not be changed orally or modified, amended or supplemented without an express written
agreement executed by the Escrow Agent, the Company, the Make Good Pledgor and the Investor Agent (upon consent of the Investor Agent). This Make Good Agreement is binding upon and intended to be for the sole benefit of the parties hereto and their
respective successors, heirs and permitted assigns, and none of the provisions of this Make Good Agreement are intended to be, nor shall they be construed to be, for the benefit of any third person.  No portion of the Escrow Shares shall be subject
to interference or control by any creditor of any party hereto, or be subject to being taken or reached by any legal or equitable process in satisfaction of any debt or other liability of any such party hereto prior to the disbursement thereof to
such party hereto in accordance with the provisions of this Make Good Agreement.

that certain Securities Purchase Agreement, of even date herewith (the
“Purchase Agreement”), pursuant to which the Investors have agreed
to purchase shares of the Common Stock of the Company, par value $0.001 per
share (“Private Offering Stock”); and

WHEREAS, the Key Holders and the Company desire to
further induce the Investors to purchase the Private Offering Stock.

NOW, THEREFORE, the Company, the Key Holders, and the
Investors each hereby agree as follows:

	 	1. 	Definitions. 

“Affiliate” means, with respect to any specified
Investor, any other Investor who or which, directly or indirectly, controls, is
controlled by or is under common control with such Investor, including without
limitation any general partner, officer, director or manager of such Investor,
and any venture capital fund now or hereafter existing which is controlled by
one or more general partners or managing members of, or shares the same
management company with, such Investor. 

“Common Stock” means shares of Common Stock of
the Company, $0.001 par value per share.

“Investors” has the meaning ascribed to it in the
Preface of this Agreement; provided, however, that any such person
shall cease to be considered an Investor for purposes of this Agreement at any
time such person and his, her or its Affiliates collectively hold fewer than
200,000 shares of Common Stock (as adjusted for any stock combination, stock
split, stock dividend, recapitalization or other similar transaction). 

“Key Holders” means Guohong Zhao, Xiaoqiu Yu and
Xiaomei Fang and each person to whom the rights of a Key Holder are assigned
pursuant to Section 3.1, and each person who hereafter becomes a
signatory to this Agreement pursuant to Section 5.9 or 5.17 and
any one of them, as the context may require.

“Proposed Key Holder Transfer” means any sale or
offer to sell, other than in an open market transaction or transaction effected
pursuant to a 10b-5 trading plan as long as the shares thus sold does not exceed
in aggregate 10% of the then issued and outstanding Common Stock in any twelve months period, an aggregate of 10% or higher of the
then issued and outstanding Common Stock proposed by any of the Key Holders to a

offering conducted by the Company in which it raises gross proceeds of at least
$20 million at a valuation of at least $120 million.

the terms and conditions specified in the Proposed Transfer Notice.

(including, without limitation, in connection with any stock split, stock

	 	2. 	Agreement Among the Company, the
      Investors and the Key Holders. 
	 	 	 
	 	  	2.1 	Right of Co-Sale. 

(a)         
Confidentiality Regarding Proposed Key Holder Transfer. In exchange for
the parties willingness to agree to these procedures, each Investor hereby
irrevocably agrees that it will hold in strict confidence the existence and
terms of any and all communications (whether written or oral) that relate in any
way to a Proposed Key Holder Transfer.

(b)         
Exercise of Right. If a Key Holder proposes to effectuate a Proposed Key
Holder Transfer, a Proposed Transfer Notice shall be delivered by the Key Holder
to each Investor after and only if such Investor has delivered to the Company a
confidentiality agreement in which such Investor agrees to keep confidential the
existence and terms of the Proposed Key Holder Transfer and not transact in any
shares of the Company’s securities until the earlier of (i) such time the
Proposed Key Holder Transfer is consummated or terminated or (ii) the Proposed
Key Holder Transfer ceases to be material non-public information such
information. Each Investor who desires to exercise its Right of Co-Sale must
give the selling Key Holder written notice to that effect within thirty (30)
days after receipt of the Proposed Transfer Notice, and upon giving such notice
such Investor shall be deemed to have effectively exercised the Right of
Co-Sale. If any Transfer Stock subject to a Proposed Key Holder Transfer is to
be sold to a Prospective Transferee, each respective Investor may elect to
exercise its Right of Co-Sale and participate on a pro rata basis in the
Proposed Key Holder Transfer as set forth in Section 2.1(b) below and
otherwise on the same terms and conditions specified in the Proposed Transfer
Notice.

2

(c)         
Shares Includable. Each Investor who timely exercises such Investor’s
Right of Co-Sale by delivering the written notice provided for above in
Section 2.1(a) may include in the Proposed Key Holder Transfer all or any
part of such Investor’s Common Stock equal to the product obtained by
multiplying (i) the aggregate number of shares of Transfer Stock subject to the
Proposed Key Holder Transfer by (ii) a fraction, the numerator of which is the
number of shares of Common Stock owned by such Investor immediately before
consummation of the Proposed Key Holder Transfer and the denominator of which is
the total number of shares of Common Stock owned, in the aggregate, by all
Investors immediately prior to the consummation of the Proposed Key Holder
Transfer, plus the number of shares of Transfer Stock held by the selling Key
Holder. To the extent one or more of the Investors exercise such right of
participation in accordance with the terms and conditions set forth herein, the
number of shares of Transfer Stock that the selling Key Holder may sell in the
Proposed Key Holder Transfer shall be correspondingly reduced.

(i)          Delivery
of Certificates. Each Investor shall effect its participation in the
Proposed Key Holder Transfer by delivering to the transferring Key Holder(s), no
later than fifteen (15) days after such Investor’s exercise of the Right of
Co-Sale, one or more stock certificates, properly endorsed for transfer to the
Prospective Transferee, representing the number of shares of Common Stock that
such Investor elects to include in the Proposed Key Holder Transfer.

(d)          Purchase
Agreement. The parties hereby agree that the terms and conditions of any
sale pursuant to this Section 2.1 will be memorialized in, and governed
by, a written purchase and sale agreement with customary terms and provisions
for such a transaction and the parties further covenant and agree to enter into
such an agreement as a condition precedent to any sale or other transfer
pursuant to this Section 2.1.

(e)         
Deliveries. Each stock certificate an Investor delivers to the selling
Key Holder pursuant to Section 2.1(b) above will be transferred to the
Prospective Transferee against payment therefor in consummation of the sale of
the Transfer Stock pursuant to the terms and conditions specified in the
Proposed Transfer Notice and the purchase and sale agreement, and the selling
Key Holder shall concurrently therewith remit or direct payment to each Investor
the portion of the sale proceeds to which such Investor is entitled by reason of
its participation in such sale. If any Prospective Transferee or Transferees
refuse(s) to purchase securities subject to the Right of Co-Sale from any
Investor exercising its Right of Co-Sale hereunder, no Key Holder may sell any
Transfer Stock to such Prospective Transferee or Transferees unless and until,
simultaneously with such sale, such Key Holder purchases all securities subject
to the Right of Co-Sale from such Investor on the same terms and conditions
(including the proposed purchase price) as set forth in the Proposed Transfer
Notice.

(f)         
Additional Compliance. If any Proposed Key Holder Transfer is not
consummated within forty-five (45) days after receipt of the Proposed Transfer
Notice by the Company, the Key Holders proposing the Proposed Key Holder
Transfer may not sell any Transfer Stock unless they first comply in full with
each provision of this Section 2. The exercise or election not to
exercise any right by any Investor hereunder shall not adversely affect its
right to participate in any other sales of Transfer Stock subject to this
Section 2.1.

3

2.2          If,
as a result of the granting or existence of the Right of Co-Sale contained
herein, the U.S. Securities and Exchange Commission (the “SEC”)
issues any comments to a registration statement or annual or periodic filing
made by the Company, which requires the modification or elimination of such
Right of Co-Sale, each of the Investors will act in good faith to discuss
whether to modify or not to exercise such right in order to allow the Company to
resolve to the satisfaction of the Company and the SEC any such comments made by
the SEC.

2.3          Effect of Failure to Comply. 

(a)         
Transfer Void; Equitable Relief. Any Proposed Key Holder Transfer not
made in compliance with the requirements of this Agreement shall be null and
void ab initio, shall not be recorded on the books of the Company or its
transfer agent and shall not be recognized by the Company. Each party hereto
acknowledges and agrees that any breach of this Agreement would result in
substantial harm to the other parties hereto for which monetary damages alone
could not adequately compensate. Therefore, the parties hereto unconditionally
and irrevocably agree that any non-breaching party hereto shall be entitled to
seek protective orders, injunctive relief and other remedies available at law or
in equity (including, without limitation, seeking specific performance or the
rescission of purchases, sales and other transfers of Transfer Stock not made in
strict compliance with this Agreement).

(b)         
Violation of Co-Sale Right. If any Key Holder purports to sell any
Transfer Stock in contravention of the Right of Co-Sale (a “Prohibited
Transfer”), each Investor who desires to exercise its Right of Co-Sale
under Section 2.1 may, in addition to such remedies as may be available
by law, in equity or hereunder, require such Key Holder to purchase from such
Investor the type and number of shares of Common Stock that such Investor would
have been entitled to sell to the Prospective Transferee under Section 2.1
had the Prohibited Transfer been effected pursuant to and in compliance with
the terms of Section 2.1. The sale will be made on the same terms and
subject to the same conditions as would have applied had the Key Holder not made
the Prohibited Transfer, except that the sale (including, without limitation,
the delivery of the purchase price) must be made within ninety (90) days after
the Investor learns of the Prohibited Transfer, as opposed to the timeframe
proscribed in Section 2.1. Such Key Holder shall also reimburse each
Investor for any and all reasonable and documented out-of-pocket fees and
expenses, including reasonable legal fees and expenses, incurred pursuant to the
exercise or the attempted exercise of the Investor’s rights under Section
2.1.

3.          Exempt Transfers. 

3.1         
Exempted Transfers. Notwithstanding the foregoing or anything to the
contrary herein, the provisions of Section 2.1 shall not apply: (a) to a
repurchase of Transfer Stock from a Key Holder by the Company at a price no
greater than that originally paid by such Key Holder for such Transfer Stock and
pursuant to an agreement containing vesting and/or repurchase provisions
approved by a majority of the Board of Directors or (b) to any transfer of
Transfer Stock by a Key Holder as a gift or without consideration, including,
without limitation, transfers for estate planning purposes; provided that
in the case of clause(s) (a) or (b), the Key Holder shall deliver prior written
notice to the Investors of such gift or transfer and such shares of Transfer Stock shall at all times remain subject to the
terms and restrictions set forth in this Agreement and such transferee shall, as
a condition to such issuance, deliver a counterpart signature page to this
Agreement as confirmation that such transferee shall be bound by all the terms
and conditions of this Agreement as a Key Holder (but only with respect to the
securities so transferred to the transferee), including the obligations of a Key
Holder with respect to Proposed Key Holder Transfers of such Transfer Stock
pursuant to Section 2.

4

3.2         
Exempted Offerings. Notwithstanding the foregoing or anything to the
contrary herein, the provisions of Section 2 shall not apply to the sale
of any Transfer Stock (a) to the public in an offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended or (b)
pursuant to a liquidation event.

3.3         
Prohibited Transferees. Notwithstanding the foregoing, no Key Holder
shall transfer any Transfer Stock to (a) any entity which, in the determination
of the Company’s Board of Directors, directly or indirectly competes with the
Company or (b) any customer, distributor or supplier of the Company, if the
Company’s Board of Directors should determine that such transfer would result in
such customer, distributor or supplier receiving information that would place
the Company at a competitive disadvantage with respect to such customer,
distributor or supplier.

4.         
Legend. The parties agree that within 180 days after the execution of
this Agreement, each of the Key Holder shall cause each certificate representing
shares of Transfer Stock held by such Key Holders or issued to any permitted
transferee in connection with a transfer permitted by Section 3(a) hereof
shall be endorsed with the following legend:

THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO, AND IN CERTAIN CASES PROHIBITED
BY, THE TERMS AND CONDITIONS OF A CERTAIN RIGHT OF CO-SALE AGREEMENT BY AND
AMONG THE STOCKHOLDER, THE CORPORATION AND CERTAIN OTHER HOLDERS OF STOCK OF THE
CORPORATION. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO
THE SECRETARY OF THE CORPORATION.

Each Key Holder agrees that the Company may instruct its
transfer agent to impose transfer restrictions on the shares represented by
certificates bearing the legend referred to in this Section 4
above to enforce the provisions of this Agreement, and the Company agrees to
promptly do so. The legend shall be removed upon termination of this Agreement

be appropriately adjusted to reflect any stock dividend, split, combination or
other recapitalization affecting the Common Stock occurring after the date of
this Agreement.

5.3         
Ownership. Each Key Holder represents and warrants that such Key Holder
is the sole legal and beneficial owner of the shares of Transfer Stock subject
to this Agreement and that no other person or entity has any interest in such
shares (other than a community property interest as to which the holder thereof
has acknowledged and agreed in writing to the restrictions and obligations
hereunder).

5.4         
Dispute Resolution. Any unresolved controversy or claim arising out of or

expressly canceled.

5.7         
Delays or Omissions. No delay or omission to exercise any right, power or
remedy accruing to any party under this Agreement, upon any breach or default of
any other party under this Agreement, shall impair any such right, power or
remedy of such non-breaching or non-defaulting party nor shall it be construed
to be a waiver of any such breach or default, or an acquiescence therein, or of
or in any similar breach or default thereafter occurring; nor shall any waiver

Holders, respectively, in the same fashion and (ii) the consent of the Key
Holders shall not be required for any amendment, modification, termination or
waiver if such amendment, modification, termination or waiver does not apply to
