Summary of
amendments to the Hudson Highland Group, Inc. 2007 Incentive Compensation Program 

The following is a summary of the
amendments to the Hudson Highland Group, Inc. (the “Company”) 2007 Incentive
Compensation Program. 

Previous formula for calculating
performance bonuses: 

	• 	Achievement
of a single corporate earnings before income tax (“EBIT”) target measured in
both dollars and as a percentage of revenue is required to earn a 100% payout and
achievement of a single corporate EBIT threshold measured in both dollars and as a
percentage of revenue is required to earn a 50% payout. 

New formula for calculating
performance bonuses: 

	• 	With
respect to performance bonuses for Jon F. Chait, the Company’s Chief Executive
Officer, and Mary Jane Raymond, the Company’s Chief Financial Officer, there has
been no modification to the previous formula. 

	• 	With
respect to performance bonuses for executive officers and corporate staff of the Company other than Mr. Chait
and Ms. Raymond, the bonus will be earned by tranche based on dollars of EBIT and EBIT as
a percentage of revenue results by region, with a tranche also for corporate performance,
as follows: 

	 	° 	21%
on North America’s EBIT target and threshold

	 	°	21%
on Europe’s EBIT target and threshold

	 	° 	21%
on Australia/New Zealand’s EBIT target and threshold

	 	° 	7%
on Asia’s EBIT target and threshold

	 	° 	30%
on Corporate EBIT target and threshold

A slightly modified formula will
apply to the other corporate staff members.efc7-2356_6292177ex41.htm

      is the owner of
                    
      Units.

    
      
         

        Each
          Unit
          (“Unit”) consists of one (1) share of common stock, par value $.0001
          per share (“Common Stock”), of NRDC Acquisition Corp., a Delaware
          corporation (the “Corporation”), and one (1) warrant (the
“Warrant”) of the Corporation. The Warrant entitles the holder to
          purchase one (1) share of Common Stock for $7.50 per share (subject to
          adjustment). The Warrant will become exercisable on the later of (i) the
          Corporation’s completion of an acquisition of one or more operating businesses
          through a merger, capital stock exchange, stock purchase, asset acquisition
          or
          other similar business combination, and
          (ii)                             ,

          time, on

          2011, or earlier upon redemption (the “Expiration Date”). The Common
          Stock and Warrants comprising the Units represented by this certificate
          are not
          transferable separately until five (5) trading days after the earlier to
          occur of the termination of the underwriters’ over-allotment option in
          connection with the Corporation’s initial public offering (the “IPO”) or
          the exercise in full by the underwriters of that option. In no event will
          the
          separate trading of the Common Stock and the Warrants comprising the Units
          represented by this certificate begin until the Corporation has filed a
          Current
          Report on Form 8-K with the Securities and Exchange Commission containing
          an
          audited balance sheet reflecting the Corporation’s receipt of the proceeds of
          its IPO and the Corporation has issued a press release announcing when
          such
          separate trading will begin. The terms of the Warrant are governed by a
          Warrant
          Agreement, dated as of
                    ,
          2007, between the Corporation and Continental Stock Transfer & Trust
          Company, as Warrant Agent, and are subject to the terms and provisions
          contained
          therein, all of which terms and provisions the holder of this certificate

    This
      certifies that ________________________, or its registered assigns, is the
      registered holder of _____________________ warrants to purchase certain
      securities (each a “Warrant”).  Each Warrant entitles
      the holder thereof, subject to the provisions contained herein and in the
      Warrant Agreement (as defined below), to purchase from NRDC Acquisition Corp.,
      a
      Delaware corporation (the “Company”), one (1) share of the
      Company’s Common Stock (each a “Share”), at the Exercise Price
      set forth below.  The exercise price of each Warrant (the
“Exercise Price”) shall be $7.50 initially, subject to
      adjustments as set forth in the Warrant Agreement.

     

    Subject
      to the terms of the Warrant Agreement (as defined below), each Warrant evidenced
      hereby may be exercised in whole, but not in part, at any time, as specified
      herein, on any Business Day (as defined below) occurring during the period

“Exercise Period”) commencing on the later of the Company’s
      consummation of a Business Combination (as defined below) or [_________], 2008
      and ending at 5:00 P.M., New York City time, on the earlier to occur of

      unexercised after 5:00 P.M., New York City time on the Expiration Date
      shall become void, and all rights of the holder of this Warrant Certificate
      evidencing such Warrant shall cease.

     

    
      
        Notwithstanding
          the above, Warrants issued as part of the co-investment units sold by the
          Company to NRDC Capital Management, LLC (the “Co-Investment
          Warrants”) may only be exercised after the date on which the last sales
          price of the Company’s common stock on the American Stock Exchange, or other
          national securities exchange on which the Company’s common stock may be traded,
          equals or exceeds $14.25 per share for any 20 trading days within any
          30-trading-day period beginning at least 90 calendar days after the Company’s
          consummation of a Business Combination (as defined below). Co-Investment
          Warrants are not redeemable by the Company.

      The
        holder of the Warrants represented by this Warrant Certificate may exercise
        any
        Warrant evidenced hereby by delivering, not later than 5:00 P.M., New York
        City time, on any Business Day during the Exercise Period (the “Exercise
        Date”) to Continental Stock Transfer & Trust Company (the
“Warrant Agent”, which term includes any successor warrant
        agent under the Warrant Agreement described below) at its corporate trust
        department at 17 Battery Place, New York, NY 10004, (i) this Warrant
        Certificate, (ii) an election to purchase (“Election to
        Purchase”), properly executed by the holder hereof on the reverse of
        this Warrant Certificate (the “Participant”) substantially in
        the form included on the reverse of this Warrant, as applicable and
        (iii) the Exercise Price for each Warrant to be exercised in lawful money
        of the United States of America by certified or official bank check or by
        bank
        wire transfer in immediately available funds[; provided,
however, that with
        respect to Warrants issued and sold in a private placement prior to the
        completion of the Company’s Initial Public Offering (as defined in the Warrant
        Agreement) and the Co-Investment Warrants, so long as any such Warrants are
        held
        by their original purchaser or its permitted transferrees, the
        holder of this Warrant Certificate may, in lieu of payment of the Exercise
        Price, surrender its Warrants for that number of shares of Common Stock equal
        to
        the quotient obtained by dividing (x) the product of the number of shares
        of
        Common Stock underlying the surrendered Warrants, multiplied by the difference
        between the Fair Market Value (defined below) and
        the
        Exercise Price by (y) the Fair Market Value.  The “Fair Market
        Value” shall mean the average reported last sale price of the Common
        Stock for the 10 trading days ending on the 3rd trading day prior to the
        date on
        which the Election to Purchase is sent to the Warrant
        Agent]2.  If
        any of (a) this Warrant Certificate, (b) the Election to Purchase, or (c)
        the Exercise Price therefor [or surrendered
        Warrants], is received by the Warrant Agent after
        5:00 P.M., New York City time, the Warrants will be deemed to be received
        and exercised on the Business Day next succeeding the date such items are
        received and such date shall be the Exercise Date for purposes
        hereof.  If the date such items are received is not a Business Day,
        the Warrants will be deemed to be received and exercised on the next succeeding
        day which is a Business Day and such date shall be the Exercise
        Date.  If the Warrants to be exercised are received or deemed to be
        received after the Expiration Date, the exercise thereof will be null and
        void
        and any funds delivered to the Warrant Agent will be returned to the holder
        as
        soon as practicable.  In no event will interest accrue on funds
        deposited with the Warrant Agent in respect of an exercise or attempted exercise
        of Warrants.  The validity of any exercise of Warrants will be
        determined by the Warrant Agent in its sole discretion and such determination
        will be final and binding upon the holder of the Warrants and the
        Company.  Neither the Warrant Agent nor the Company shall have any
        obligation to inform a holder of Warrants of the invalidity of any exercise
        of
        Warrants.

    

     

    As
      used
      herein, the term “Business Day” means any day that is not a
      Saturday or Sunday and is not a United States federal holiday or a day on which
      banking institutions generally are authorized or obligated by law or regulation
      to close in New York City.

     

    As
      used
      herein, the term “Business Combination” shall mean the initial
      acquisition by the Company of one or more operating businesses through a merger,
      capital stock exchange, stock purchase, asset acquisition or other similar
      business combination having collectively, a fair market value (as calculated
      in
      accordance with the Company’s Second Amended and Restated Certificate of
      Incorporation, as the same may be amended from time to time) of at least 80%
      of
      the amount in the trust account established by the Company at the completion
      of
      its initial public offering (excluding the Underwriters’ (as defined in the
      Warrant Agreement) deferred discount) at the time of such
      acquisition.

     

    Warrants
      may be exercised only in whole numbers of Warrants.  No fractional
      shares of Common Stock are to be issued upon the exercise of any Warrant, but
      rather the number of shares of Common Stock to be issued shall be rounded up
      to
      the nearest whole number.  If fewer than all of the Warrants evidenced
      by this Warrant Certificate are exercised, a new Warrant Certificate for the
      number of Warrants remaining unexercised shall be executed by the Company and
      countersigned by the Warrant Agent as provided in Section 2 of the Warrant
      Agreement, and delivered to the holder of this Warrant Certificate at the
      address specified on the books of the Warrant Agent or as otherwise specified
      by
      such Registered Holder.

     

    Notwithstanding
      the foregoing, the Company shall not be obligated to deliver any Shares pursuant
      to the exercise of a Warrant and shall have no obligation to settle a Warrant
      exercise unless a registration statement under the Securities Act of 1933,
      as
      amended (the “Securities Act”), with respect to the Shares is
      effective and a

      To be included only in Warrant Certificates representing (i) Warrants issued
      in
      the private placement or (ii) the Co-Investment Warrants, in both instances
      only
      so long as held by the original holder or a permitted transferee.

    

    
      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

    

     

    current
      prospectus is on file with the Commission. In
      the event that a registration statement with respect to the Shares underlying a Warrant is not effective under the
      Securities Act or
      a current prospectus is not on file with the Commission, the holder of such
      Warrant shall not be entitled to exercise such Warrant. Notwithstanding anything
      to the contrary in the Warrant Agreement (as defined below) and this Warrant
      Certificate, under no circumstances will the Company be required to net cash
      settle a Warrant exercise. Warrants may not be exercised by, or Shares issued
      to, any registered holder in any state in which such exercise or issuance would
      be unlawful. For the avoidance of doubt, as a result of Section 3.3.4 of the
      Warrant Agreement and the foregoing, any or all of the Warrants may expire
      unexercised.

     

    This
      Warrant Certificate is issued under and in accordance with the Warrant
      Agreement, dated as of [________], 2007 (the “Warrant
      Agreement”), between the Company and the Warrant Agent and is subject
      to the terms and provisions contained in the Warrant Agreement, to all of which
      terms and provisions the holder of this Warrant Certificate and the beneficial
      owners of the Warrants represented by this Warrant Certificate consent by
acceptance
      hereof.  Copies of the Warrant Agreement are on file and can be
      inspected at the above-mentioned office of the Warrant Agent and at the office
      of the Company at 3 Manhattanville Road, Purchase, NY 10577.

     

    At
      any
      time during the Exercise Period, the Company may, at its option, redeem all
      (but
      not part) of the then outstanding Warrants upon giving notice in accordance
      with
      the terms of the Warrant Agreement (the “Redemption Notice”),
      at the price of $0.01 per Warrant (the “Redemption Price”);
provided, that the last sales price of the Common Stock on
      the American
      Stock Exchange, or other principal market on which the Common Stock may be
      traded, equals or exceeds $14.25 per share (subject to adjustment as provided
      in
      the Warrant Agreement) for any 20 trading days within a 30 trading day period
      ending three business days prior to the date on which the Redemption Notice
      is
      given, and a registration statement under the Securities Act relating to shares
      of Common Stock issuable upon exercise of the Warrants is effective and expected
      to remain effective to and including the Redemption Date (as defined below)
      and
      a prospectus relating to the shares of Common Stock issuable upon exercise
      of
      the Warrants is available for use to and including the Redemption
      Date.  In the event the Company shall elect to redeem all of the then
      outstanding Warrants, the Company shall fix a date for such redemption (the
      “Redemption Date”); provided, that such date shall occur
      prior to the expiration of the Exercise Period.  The Warrants may be
      exercised in accordance with the terms of this Agreement at any time after
      a
      Redemption Notice shall have been given by the Company; provided,
however, that no Warrants may be exercised subsequent to the expiration
      of the Exercise Period; provided, further, that all rights
      whatsoever with respect to the Warrants shall cease on the Redemption Date,
      other than to the right to receive the Redemption Price.  Notwithstanding
      the foregoing, the Co-Investment Warrants are not redeemable by the
      Company.

     

    The
      accrual of dividends, if any, on the Shares issued upon the valid exercise
      of
      any Warrant will be governed by the terms generally applicable to such
      Shares.  From and after the issuance of such Shares, the former holder
      of the Warrants exercised will be entitled to the benefits generally available
      to other holders of Shares and such former holder’s right to receive payments of
      dividends and any other amounts payable in respect of the Shares shall be
      governed by, and shall be subject to, the terms and provisions generally
      applicable to such Shares.

     

    The
      Exercise Price and the number of Shares purchasable upon the exercise of each
      Warrant shall be subject to adjustment as provided pursuant to Section 4 of
      the
      Warrant Agreement.

     

    Prior
      to
      the Detachment Date, the Warrants represented by this Warrant Certificate may
      be
      exchanged or transferred only together with the Shares to which such Warrant
      is
      attached (together, a “Unit”), and only for the purpose of
      effecting, or in conjunction with, an exchange or transfer of such
      Unit.  Additionally, prior to the Detachment Date, each transfer of
      such Unit on the register of the Units shall operate also to transfer the
      Warrants included in such Units.  From and after the Detachment Date,
      the above provisions shall be of no further force and effect.  Upon
      due presentment for registration of transfer or exchange of this Warrant
      Certificate at the stock transfer division of the Warrant Agent, the Company
      shall execute, and the Warrant Agent shall countersign and deliver, as provided
      in Section 5 of the Warrant Agreement, in the name of the designated transferee
      one or more new Warrant Certificates of any authorized denomination evidencing
      in the aggregate a like number of unexercised Warrants, subject to the
      limitations provided in the Warrant Agreement.3

        be included
        only in Warrant Certificates representing Warrants sold in the Company’s public
        offering.

    

    

    
      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

    

    
       

      Neither
        this Warrant Certificate nor the Warrants evidenced hereby shall entitle
        the
        holder hereof or thereof to any of the rights of a holder of the Shares,
        including, without limitation, the right to receive dividends, if any, or
        payments upon the liquidation, dissolution or winding up of the Company or
        to
        exercise voting rights, if any.

       

      The
        Warrant Agreement and this Warrant Certificate may be amended as provided
        in the
        Warrant Agreement including, under certain circumstances described therein,
        without the consent of the holder of this Warrant Certificate or the Warrants
        evidenced hereby.

       

      THIS
        WARRANT CERTIFICATE AND ALL RIGHTS HEREUNDER AND UNDER THE WARRANT AGREEMENT
        SHALL BE GOVERNED BY AND INTERPRETED AND CONSTRUED IN ACCORDANCE WITH THE
        LAWS
        OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS FORMED AND TO BE PERFORMED
        ENTIRELY WITHIN THE STATE OF NEW YORK, WITHOUT  REGARD
        TO THE CONFLICTS OF LAW PROVISIONS THEREOF TO THE EXTENT SUCH PRINCIPLES
        OR
        RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER
        JURISDICTION.

    

     

    This
      Warrant Certificate shall not be entitled to any benefit under the Warrant
      Agreement or be valid or obligatory for any purpose, and no Warrant evidenced
      hereby may be exercised, unless this Warrant Certificate has been countersigned
      by the manual or facsimile signature of the Warrant Agent.

     

    IN
      WITNESS WHEREOF, the Company has caused this instrument to be duly
      executed.
