Recital




WHEREAS,
the Existing Shareholders have agreed as a condition of the Stern Participants’
closing the transactions contemplated by the Master Acquisition Agreement dated
December 10, 2009, by and among the Company, the Stern Participants, and other
parties (the “Master
Acquisition Agreement”) to enter into this Agreement.




IT
IS AGREED:




1.  Exercise or Sale of
Warrants.




(a)  Following
the later of (i) six (6) months after the Closing and (ii) Registration
Statement Effective Date (the “Trigger Date”), each of the Existing Shareholders
agrees to exercise for cash or sell all of the Private Placement Warrants owned
by them (the “Covered
Warrants”).  The Existing Shareholders shall exercise for cash
or sell on average for each day after the Trigger Date that the last reported
sales price of the Company’s Ordinary Shares on The Nasdaq Stock Market, LLC is
greater than $9.00 (the “Closing Price Threshold”) a
number of Covered Warrants equal to the greater of (A) ten (10%) percent of the
ADTV of the Company’s Ordinary Shares for each day after the Trigger Date that
the Closing Price Threshold was satisfied or (B) 50,000 Covered
Warrants.  The average daily number of Covered Warrants exercised for
cash or sold shall be measured on a weekly basis beginning with the week in
which the Closing Price Threshold is first met after the Trigger Date and on a
cumulative basis each week thereafter.  Sales of Covered Warrants
shall be included as sales for purposes of the foregoing calculation, whether
sold in a reported transaction or in a private placement
transaction.




(b)  The
Existing Shareholders shall coordinate their exercises and sales of the Covered
Warrants so as to satisfy the requirements of Section 1(a) as
follows:




(i)  Immediately
following the Trigger Date, each Existing Shareholder shall notify the Agent in
writing of the (A) number of Covered Warrants they elect to exercise with cash
from the sale of other such Covered Warrants (the “Cashless Exercise Warrants”);
(B) the number of such Warrants they elect to exercise from other cash resources
and the date on which they intend to exercise such Warrants; and (C) the number
of such Warrants they direct the Agent to sell on their behalf (the “Sale
Warrants”).  If, based upon the notices received by the Agent
from the Existing Shareholders, the Agent determines that the Existing
Shareholders will not be able to satisfy their obligations under Section 1, it
shall revise the desired sales and exercises by the Existing Shareholders as it
deems appropriate to allow the Existing Shareholders to satisfy their
obligations under Section 1 and so shall notify the Existing Shareholders of
revisions to their notices.  Each Existing Shareholder may change such
designation from time to time by written notice to the Agent; provided that such
change does not adversely impact the ability of the Existing Shareholders to
satisfy their obligations under Section 1, as determined in the sole discretion
of the Agent.




1


(ii)  The Agent
shall coordinate the sale of the Sale Warrants by the Existing Shareholders so
as to satisfy the requirements of Section 1(a), when taken in conjunction with
Covered Warrants exercised by the Existing Shareholders.




(iii)  To the
extent an Existing Shareholder elects to exercise Cashless Exercise Warrants,
the proceeds from the first Covered Warrants owned by that Existing Shareholder
sold by the Agent shall be used to exercise such Warrants on behalf of the
Existing Shareholder.




(iv)  The Agent
shall sell Covered Warrants in such order, numbers, proportions, times, prices,
manner, including private sales, market trades or block purchases, and other
terms as the Agent shall determine in its sole discretion, and the Agent is not
required to sell Covered Warrants on a proportionate basis among the Existing
Shareholders.




(v)  If an
Existing Shareholder fails to exercise a Covered Warrant within seven (7) days
after the date indicated in its written notice, the Agent is authorized to sell
those Covered Warrants on behalf of the Existing Shareholder.




(vi)  The Agent
will remit net proceeds from the sale of Covered Warrants directly to the
Existing Shareholders who own such Warrants.




(c)  A sale to
a Permitted Transferee shall not be deemed to be a sale for purposes of this
Agreement.




(d)  Each of
the Existing Shareholders shall not exercise any of the Private Placement
Warrants held by them, except for cash.




(e)  The
Existing Shareholders will sell the Covered Warrants only to persons who agree
in writing to exercise such warrants within fifteen (15) days after they
purchase such warrants from the Existing Shareholdersand will
cooperate with the Stern Participants as is reasonably necessary to enforce such
obligation.




(f)  To the
extent permitted by applicable law, the Company agrees to allow the Agent to pay
the exercise price of the Covered Warrants sold for its own account or for the
accounts of the Existing Shareholders by delivery of a binding written
commitment, in a form reasonably acceptable to the Company, to pay the exercise
price of the Covered Warrants being exercised within fifteen (15) days following
the delivery of the subscription form required for the exercise of the
warrant.




2


(g)  The
Company agrees that as promptly as possible following the closing of the
transactions contemplated by the Master Acquisition Agreement, the Company shall
file with the SEC the registration statement described in the definition of
Registration Statement Effective Date and shall take such actions as are
necessary to qualify for sale the securities covered by such registration
statement in those states in which the such securities were initially offered by
the Company.  The Company shall cause the such registration statement
to become effective as soon as is reasonably possible and to maintain the
effectiveness of such registration statement until at least the Termination
Date.




2.  Transfer
Restrictions.  The Existing Shareholders shall not transfer or
assign any of the Covered Warrants owned by them to a Permitted Transferee
unless the Permitted Transferee agrees in writing to be bound by the terms and
conditions of this Agreement.




3.  Amendments to
Warrants.  The Existing Shareholders will not agree to any
amendments to the Private Placement Warrants without the consent of the Stern
Participants.




4.  Escrow.  Prior
to the Termination Date, the outstanding Private Placement Warrants shall be
held in escrow pursuant to the terms of the Private Placement  Warrant
Escrow Agreement, as amended as set forth in Exhibit
