     This First Amendment to Employment Agreement, dated as of the 4th day of

the Company desire to: (i) terminate the Initial Incentive Awards granted

Cash Plan; and (ii) amend the Employment Agreement to provide that Annual Awards
will be granted to Executive under the Cash Plan.

     B. Section 4 of the Employment Agreement is deleted in its entirety and
replaced with the following:

          4. Long Term Incentive Plan Grants.

                    (a) Annual Grants. Commencing with 2008, and continuing for
               each calendar year during the Employment Period, Executive shall
               receive an annual grant of awards under the Company's Long-Term
               Incentive Cash Award Plan adopted by the Board on March 4, 2008,
               as the same may be amended (the "Cash Plan") equal to (as of the
               date of the grant) the aggregate of Executive's (i) then current
               Base Salary and (ii) the Target Bonus then in effect (the "Annual
               Award"). The Annual Awards shall be fixed and determined in
               accordance with, and shall be subject to any conditions set forth
               in the Cash Plan and the granting document(s).

                    (b) Initial Grants. Effective as of the date on which the
               Board adopts the Cash Plan (the "Plan Date"), Executive is hereby
               granted pursuant to the Cash Plan (i) a number of stock
               appreciation rights equal to the sum of 180,941 plus a number
               stock appreciation rights having a Black-Scholes value equal to
               the difference between the Strike Price (as hereinafter
               determined) and $16.75 multiplied by 180,941 (the "Initial
               SARs"), and (ii) 89,552 phantom shares (the "Initial Phantom
               Shares" and collectively, with the Initial SARs, the "Initial
               Incentive Awards") to replace and in full substitution for the
               Initial Incentive Awards granted pursuant to the Employment
               Agreement. The Initial SARs will (x) have a Strike Price (within
               the meaning of the Cash Plan) equal to the higher of the closing
               market price of the Company's Class A shares of common stock on
               the Plan Date or on the third (3rd) business day after the
               Company files its

               Annual Report on Form 10-K for its fiscal year ended December 31,
               2007, (y) expire on August 13, 1014, and (z) vest in three (3)
               tranches, with one-third of the Initial SARs exercisable on
               August 13, 2008, one-third on August 13, 2009, and one-third on
               August 13, 2010. The Initial Phantom Shares will vest, and will
               be settled as of, August 13, 2010, if Executive remains employed
               by the Company for the full term of Employment Period. The number
               of Initial SARS will be determined by the compensation consulting
               firm of Lyons, Benenson & Company, Inc., promptly communicated to
               Executive, and included in the Award Agreement relating to the
               Initial Incentive Awards. The Initial Incentive Awards shall be
               subject to any conditions set forth in the Cash Plan and the
               granting document(s).

     C. The first sentence of Section 8(b) of the Employment Agreement is
deleted in its entirety and replaced with the following:

                    (b) Termination Payments - Termination by Executive. If
               Executive voluntarily terminates his employment (i) without Good
               Reason, or (ii) without Good Reason on Change of Control, then
               Executive shall be entitled to receive: (A) a cash payment equal
               to the aggregate amount of (x) accrued but unpaid Base Salary and
               (y) unused vacation days; (B) settlement of any then vested
               Initial Phantom Shares and Phantom Shares (as defined in the Cash
               Plan); and (C) the ability to exercise any then vested Initial
               Incentive Award and Annual Awards in accordance with their terms.

The balance of Section 8(b) of the Employment Agreement shall remain unchanged.

                    (g) Termination Payments - Disability. If Executive is
               terminated by the Company for a Disability (as hereinafter
               defined), then Executive shall be entitled to receive: (i) a cash
               payment equal to the aggregate amount of (A) accrued but unpaid
               Base Salary, (B) unused vacation days, and (C) the Target Bonus
               on a pro rata basis through the Termination Date; (D) settlement
               of any then vested Initial Phantom Shares and Phantom Shares; and
               (ii) the immediate vesting of the next tranche of Initial SARs
               and SARs (as defined in the Cash Plan) that would have vested
               after the Termination Date under any Initial Incentive Award and
               Annual Awards; and (iii) the ability to exercise any then vested
               Initial Incentive Award and Annual Awards in accordance with
               their terms.

The balance of Section 8(g) of the Employment Agreement shall remain unchanged.

     E. Section 16 of the Employment Agreement is deleted in its entirety and
replaced with the following:

          16. Conflict. In the event of a conflict between the terms of this
          Agreement and the Cash Plan or the Company's Annual Incentive Plan,
          this Agreement shall control.

3. Termination of Options and Units. Executive and the Company agree that upon
grant of the Initial SARs and Initial Phantom Shares, the grants of the Units
and Options as provided in the Employment Agreement, and any related granting
documents will be immediately terminated and of no further force or effect.

Employment Agreement and the terms of this Amendment, the terms of this
Amendment shall control.

5. Employment Agreement. The Employment Agreement, as hereby amended, shall
continue in full force and effect, to the fullest extent not inconsistent with
this Amendment.
