OpCo shall be less than the amount of CNY 82,000,000, the Parties shall cause HoldCo to make
available to OpCo such financial assistance or security or other credit support to ensure that
the total funding made available to OpCo shall be equivalent to CNY 82,000,000.(d)
    
    Any issuance of HoldCo Securities that will result in the aggregate value of all HoldCo
Securities outstanding after such issuance to exceed the amount of CNY 82,000,000 (or its

    HoldCo, OpCo and any other Operating Company shall to the extent possible independently
obtain all credit facilities from third Persons necessary to meet their respective working
capital requirements and debt obligations.(b)
    
    If any Operating Company requires funding in excess of that originally contemplated by the
Parties (including, in the case of OpCo, the funding requirements set out in Article 2.2), and
HoldCo and such Operating Company are unable to obtain such additional funding on an
independent basis, the Parties shall exert their best efforts to make available to such
Operating Company appropriate financial assistance or security or other credit support to
enable the Operating Companies to obtain such credit facilities. Any additional funding or
credit support to be provided by the Parties shall be borne by them in proportion to their
respective Percentage Interests; provided, however, that HoldCo has a sole discretion to
determine the method to obtain the funding or credit support, which may include additional
subscriptions to shares in the capital stock of the relevant Operating Company or loans or
other credit facilities obtained by such Operating Company from banks or other financial
institutions.(c)
    
    For the avoidance of doubt, nothing in this Article 3.2 shall be interpreted as requiring any
Party to extend debt financing to, make contributions to the equity of, or issue any
guarantee, security or other credit support for the financing requirements of, any Operating
Company.

ARTICLE 4. OPERATION AND MANAGEMENT
 Operation of HoldCo
  Directors
 (a)
    
    Unless otherwise agreed by the Shareholders in accordance with this Agreement and the
Japanese Company Law, the Board shall be comprised of five members. For so long as Recruit
and 51 Job hold their respective Percentage Interests of all outstanding HoldCo Securities,
three Directors shall be nominees of Recruit (each a Recruit Director) and two Directors
shall be nominees of 51 Job (each a 51 Job Director).(b)
    
    In the event of any Transfer of HoldCo Securities by an Party or any other occurrence that
dilutes the percentage of outstanding HoldCo Securities held by that Party (such that the
percentage of outstanding HoldCo Securities held by such Party is less than its Percentage
Interest), the number of directors that such Party may nominate shall be reduced to such
number as corresponds to such Partys proportionate interest in the total outstanding HoldCo
Securities after the Transfer, and such Party shall cause the corresponding number of its
nominees to the board of directors to resign as directors. In the event of any Transfer of
HoldCo Securities to a Party or any other occurrence that increases the percentage of
outstanding HoldCo Securities held by such Party (such that the percentage of outstanding
HoldCo Securities held by it exceeds its Percentage Interest), the number of Directors that
such other Party may nominate shall be increased by such number as will result in such Partys
being able to nominate a number of Directors that corresponds to such Partys proportionate
interest in the total outstanding HoldCo Securities after the Transfer.(c)
    
    Any Director may be removed for cause and by the procedures in accordance with the Japanese
Company Law; provided, however, that (i) without prior written consent from 51 Job, any 51 Job
Director may not be removed and (ii) without prior written consent from Recruit, any Recruit
Director may not be removed. In addition, each Party shall have the right, in its sole
discretion, to remove its own nominee Directors at any time, and the other Party agrees to
take such other steps as are within its power in order promptly to remove such Director.(d)
    
    In the case of a vacancy in the Board for any reason (including removal pursuant to the
preceding paragraph), the vacancy shall be filled by the Party having the right to nominate
the Director previously occupying the position left vacant, and the other Party agrees to take
such steps to cause the election of the individual so nominated, unless such individual is
disqualified by law from acting as a Director.

judgments, suits, costs, expenses and disbursements (including, without limitation, reasonable
fees and disbursements of counsel incurred in connection therewith) incurred by the
Indemnified Party arising out of or in connection with such events, except to the extent that
the Indemnified Partys own bad faith, willful misconduct or gross negligence contributes to
such loss, liability, damage claim or expense.(e)

procedure shall be initiated pursuant to which the Non-Defaulting Party may, by delivering

of the then-current fair market value of Shares (such notice, the Call Notice and such
procedure, the Call Procedure).In case of early termination of this Agreement pursuant to Article 10.2(b) and (c) (except
for the case (2) of second paragraph of Article 10.2(c)), a procedure shall be initiated
pursuant to which the Party that is terminating this Agreement may, by delivering written
