FORM
OF MAY 18, 2010 RESTRICTED SHARE AGREEMENT WITH DIRECTORS





This
Restricted Share Agreement (this “Agreement”) is by and
between ATS Corporation, a Delaware corporation (the “Corporation”), and
_______ (the “Participant”), a
director of the Corporation or one or more of its subsidiaries, and is effective
as of May 18, 2010 (the “Effective
Date”).




1.           Award of Restricted
Shares.  Subject to the provisions of the ATS Corporation 2006
Omnibus Incentive Compensation Plan (the “Plan”) and this
Agreement, the Corporation hereby grants to the Participant 8,275 shares (the
“Award”) of the
Corporation’s common stock, par value $0.0001 per share (the “Common Stock”), to
which the restrictions referred to in Section 2 (the “Vesting Conditions”)
attach (the “Restricted
Shares”).




2.           Vesting
Conditions.




(a)           Vesting
Schedule.  The 8,275 Restricted Shares shall be initially
unvested (the unvested shares of Restricted Shares are referred to in this
Agreement as the “Unvested Shares”) and
shall fully vest, if at all, as provided in this Section 2 over the period
ending May 1, 2011 (the “Vesting Period”),
except as otherwise expressly provided in section 2(b) below, provided that the
Participant is serving as a director of the Corporation on such date (the “Vesting
Date”).




(b)           Other
Vesting.  Notwithstanding anything to the contrary contained in
this Section 2, all of the Restricted Shares shall vest immediately upon a
“Change of Control,” as defined below, at any time prior to the satisfaction of
the Vesting Conditions. For purposes of this Agreement, a “Change in Control”
shall mean an occurrence of any of the following events:




(i)
            an
      acquisition (other than directly from the Corporation) of any voting
      securities of the Corporation (the “Voting
      Securities”) by any “person or group” (within the meaning of
      Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934 (the
      “Exchange
      Act”)) other than an employee benefit plan of the Corporation,
      immediately after which such person or group has “Beneficial Ownership”
      (within the meaning of Rule 13d-3 under the Exchange Act) of more than
      fifty percent (50%) of the combined voting power of the Corporation's then
      outstanding Voting Securities; or







(ii)
            the
      consummation of (1) a merger, consolidation or reorganization involving
      the Corporation, unless the company resulting from such merger,
      consolidation or reorganization (the “Surviving
      Corporation”) shall adopt or assume this Agreement and the
      stockholders of the Corporation immediately before such merger,
      consolidation or reorganization own, directly or indirectly immediately
      following such merger, consolidation or reorganization, at least fifty
      percent (50%) of the combined voting power of the Surviving Corporation in
      substantially the same proportion as their ownership immediately before
      such merger, consolidation or reorganization, (2) a complete liquidation
      or dissolution of the Corporation, or (3) a sale or transfer of all or
      substantially all of the assets of the
  Corporation.




3.           Rights During Vesting
Period.  The Participant generally does not have the rights and
privileges of a stockholder as to the Restricted Shares to be distributed until
he has become the holder of such Restricted Shares.  Further,
notwithstanding any other provision hereof, the following restrictions shall
apply to shares of Restricted Shares prior to satisfaction of the Vesting
Conditions as to those shares:  (a) the Participant shall not be
entitled to delivery of a certificate for the Restricted Shares until the
satisfaction of the Vesting Conditions; (b) none of the Restricted Shares
may be sold, assigned, transferred (except by will or the laws of descent and
distribution), pledged or otherwise encumbered prior to satisfaction of the
Vesting Conditions; and (c) except as otherwise expressly provided herein
and in the Plan, the Participant shall forfeit and immediately transfer back to
the Corporation without payment all of the Restricted Shares, and all rights of
the Participant to such Restricted Shares shall terminate without further
obligation on the part of the Corporation, if and when the Participant ceases to
be a director of the Corporation prior to the satisfaction of the Vesting
Conditions.  As a condition of the Award, the Corporation may require
the Participant to deliver to the Corporation a duly signed stock power,
endorsed in blank, with respect to the shares of Common Stock subject to the
Award.




4.           Satisfaction of Vesting
Conditions.  Upon the satisfaction of the Vesting Conditions as
to particular shares of Restricted Shares, the restrictions on the applicable
number of shares of Restricted Shares shall terminate and a stock certificate
for such number of shares of Common Stock shall be delivered, free and clear of
all such restrictions, to the Participant or, subject to Section 5, the
Participant’s beneficiary or estate, as the case may be, subject to the
provisions of Sections 7 and 8(e).  The Corporation shall not be
required to deliver any fractional share of Common Stock, but will pay, in lieu
thereof, the fair market value of such fractional share to the Participant or
the Participant’s beneficiary or estate, as the case may be.  The
Corporation shall pay any original issue tax that may be due upon the issuance
of the Restricted Shares and all other costs incurred by the Corporation in
issuing such shares of Common Stock.




5.           Nontransferability of
Restricted Shares.  The Restricted Shares are not transferable
by the Participant prior to the satisfaction of the Vesting Conditions except by
will or the laws of descent and distribution.  Without limiting the
generality of the foregoing, prior to the expiration of the Vesting Conditions,
the Award and Restricted Shares may not be assigned, alienated, pledged,
attached, sold or otherwise transferred except as aforesaid, or
encumbered.  Any attempted assignment, alienation, pledge, attachment,
sale, transfer or other encumbrance or disposition of the Restricted Shares
contrary to the provisions hereof, or the levy of any execution, attachment or
similar process upon the Restricted Shares, shall be null and void and without
effect.

6.           Adjustments for Changes in
Capitalization and Similar Events.  The committee of the
Corporation designated by the Board of Directors to administer the Plan (the
“Committee”)
has the discretion to make an adjustment to the Restricted Shares in the event
the Corporation engages in a dividend or other distribution (whether in the form
of cash, shares, other securities or other property), recapitalization, stock
split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off, combination, repurchase or exchange of shares or other securities of
the Corporation, issuance of warrants or other rights to purchase shares or
other securities of the Corporation, or other similar
transactions.  If such an adjustment is deemed appropriate or
desirable by the Committee, then it may adjust any or all of the terms of this
Agreement, including (i) the number of Restricted Shares or other securities of
the Corporation (or number and kind of other securities or property) subject to
this Agreement; or (ii) make provision for a cash payment to the Participant in
consideration for the cancellation of such Award.
