shares of Common Stock into a smaller number of shares, the number of Shares
issuable upon exercise of this Warrant at the time of the record date for such
dividend or distribution or the effective date of such subdivision, combination
or reclassification shall be proportionately adjusted so that the Warrantholder
after such date shall be entitled to purchase the number of shares of Common
Stock which such holder would have owned or been entitled to receive in respect
of the shares of Common Stock subject to this Warrant after such date had this
Warrant been exercised immediately prior to such date. In such event, the
Exercise Price in effect at the time of the record date for such dividend or
distribution or the effective date of such subdivision, combination or
reclassification shall be adjusted to the number obtained by dividing (x) the
product of (1) the number of Shares issuable upon the exercise of this Warrant
before such adjustment and (2) the Exercise Price in effect immediately prior to
the record or effective date, as the case may be, for the dividend,
distribution, subdivision, combination or reclassification giving rise to this
adjustment by (y) the new number of Shares issuable upon exercise of the Warrant
determined pursuant to the immediately preceding sentence.

    

    
       

      (B)              Certain Issuances of Common
Shares or Convertible Securities. Until the earlier of (i) the date on

thereof and (ii) the third anniversary of the Issue Date, if the Company shall
issue shares of Common Stock (or rights or warrants or other securities

(other than in Permitted Transactions (as defined below) or a transaction
to which subsection (A) of this Section 13 is applicable) without consideration
or at a consideration per share (or having a conversion price per share) that is
less than 90% of the Market Price on the last trading day preceding the date of
the agreement on pricing such shares (or such convertible securities) then, in
such event:

    

    
       

      (A)         the
number of Shares issuable upon the exercise of this Warrant immediately prior to
the date of the agreement on pricing of such shares (or of such convertible
securities) (the "Initial
Number") shall be increased to the number obtained by multiplying the
Initial Number by a fraction (A) the numerator of which shall be the sum of (x)
the number of shares of Common Stock of the Company outstanding on such date and
(y) the number of additional shares of Common Stock issued (or into which
convertible securities may be exercised or convert) and (B) the denominator of
which shall be the sum of (I) the number of shares of Common Stock outstanding
on such date and (II) the number of shares of Common Stock which the aggregate
consideration receivable by the Company for the total number of shares of Common
Stock so issued (or into which convertible securities may be exercised or
convert) would purchase at the Market Price on the last trading day preceding
the date of the agreement on pricing such shares (or such convertible
securities); and

    

    
       

      (B)              the
Exercise Price payable upon exercise of the Warrant shall be adjusted by
multiplying such Exercise Price in effect immediately prior to the date of the
agreement on pricing of such shares (or of such convertible securities) by a
fraction, the numerator of which shall be the number of shares of Common Stock
issuable upon exercise of this Warrant prior to such date and the denominator of
which shall be the number of shares of Common Stock issuable upon exercise of
this Warrant immediately after the adjustment described in clause (A)
above.

    


    
      
         


      

      
        
        

        
          

        

      

      
         


      

    

    
       

      For
purposes of the foregoing, the aggregate consideration receivable by the Company
in connection with the issuance of such shares of Common Stock or convertible
securities shall be deemed to be equal to the sum of the net offering price
(including the Fair Market Value of any non-cash consideration and after
deduction of any related expenses payable to third parties) of all such
securities plus the minimum aggregate amount, if any, payable upon exercise or
conversion of any such convertible securities into shares of Common Stock; and
"Permitted Transactions"
shall mean issuances (i) as consideration for or to fund the acquisition
of businesses and/or related assets, (ii) in connection with employee benefit
plans and compensation related arrangements in the ordinary course and
consistent with past practice approved by the Board of Directors, (iii) in
connection with a public or broadly marketed offering and sale of Common Stock
or convertible securities for cash conducted by the Company or its affiliates
pursuant to registration under the Securities Act or Rule 144A thereunder on a
basis consistent with capital raising transactions by comparable financial
institutions and (iv) in connection with the exercise of preemptive rights on
terms existing as of the Issue Date. Any adjustment made pursuant to this
Section 13(B) shall become effective immediately upon the date of such
issuance.

    

    
       

      (C)           Other Distributions.
In case the Company shall fix a record date for the making of a distribution to
all holders of shares of its Common Stock of securities, evidences of
indebtedness, assets, cash, rights or warrants (excluding Ordinary Cash
Dividends, dividends of its Common Stock and other dividends or distributions
referred to in Section 13(A)), in each such case, the Exercise Price in effect
prior to such record date shall be reduced immediately thereafter to the price
determined by multiplying the Exercise Price in effect immediately prior to the
reduction by the quotient of (x) the Market Price of the Common Stock on the
last trading day preceding the first date on which the Common Stock trades
regular way on the principal national securities exchange on which the Common
Stock is listed or admitted to trading without the right to receive such
distribution, minus the amount of cash and/or the Fair Market Value of the
securities, evidences of indebtedness, assets, rights or warrants to be so
distributed in respect of one share of Common Stock (such amount and/or Fair
Market Value, the "Per Share
Fair Market Value") divided by (y) such Market Price on such date
specified in clause (x); such adjustment shall be made successively whenever
such a record date is fixed, In such event, the number of Shares issuable upon
the exercise of this Warrant shall be increased to the number obtained by
dividing (x) the product of (1) the number of Shares issuable upon the exercise
of this Warrant before such adjustment, and (2) the Exercise Price in effect
immediately prior to the distribution giving rise to this adjustment by (y) the
new Exercise Price determined in accordance with the immediately preceding
sentence. In the case of adjustment for a cash dividend that is, or is
coincident with, a regular quarterly cash dividend, the Per Share Fair Market
Value would be reduced by the per share amount of the portion of the cash
dividend that would constitute an Ordinary Cash Dividend. In the event that such
distribution is not so made, the Exercise Price and the number of Shares
issuable upon exercise of this Warrant then in effect shall be readjusted,
effective as of the date when the Board of Directors determines not to
distribute such shares, evidences of indebtedness, assets, rights, cash or
warrants, as the case may be, to the Exercise Price that would then be in effect
and the number of Shares that would then be issuable upon exercise of this
Warrant if such record date had not been fixed.

    

    
       

      (D)              Certain Repurchases of
Common Stock. In case the Company effects a Pro Rata Repurchase of Common
Stock, then the Exercise Price shall be reduced to the price determined by
multiplying the Exercise Price in effect immediately prior to the Effective Date
of such Pro Rata Repurchase by a fraction of which the numerator shall be (i)
the product of (x) the number of shares of Common Stock outstanding immediately
before such Pro Rata Repurchase and (y) the Market Price of a share of Common
Stock on the trading day immediately preceding the first public announcement by
the Company or any of its Affiliates of the intent to effect such Pro Rata
Repurchase, minus (ii) the aggregate purchase price of the Pro Rata Repurchase,
and of which the denominator shall be the product of (i) the number of shares of
Common Stock outstanding immediately prior to such Pro Rata Repurchase minus the
number of shares of Common Stock so repurchased and (ii) the Market Price per
share of Common Stock on the trading day immediately preceding the first public
announcement by the Company or any of its Affiliates of the intent to effect
such Pro Rata Repurchase. In such event, the number of shares of Common Stock
issuable upon the exercise of this Warrant shall be increased to the number
obtained by dividing (x) the product of (1) the number of Shares issuable upon
the exercise of this Warrant before such adjustment, and (2) the Exercise Price
in effect immediately prior to the Pro Rata Repurchase giving rise to this
adjustment by (y) the new Exercise Price determined in accordance with the
immediately preceding sentence. For the avoidance of doubt, no increase to the
Exercise Price or decrease in the number of Shares issuable upon exercise of
this Warrant shall be made pursuant to this Section
13(D).

    


    
      
         


      

      
        
        

        
          

        

      

      
         


      

    

    
       

      (E)              Business
Combinations. In case of any Business Combination or reclassification of
Common Stock (other than a reclassification of Common Stock referred to in
Section 13(A)), the Warrantholder's right to receive Shares upon exercise of
this Warrant shall be converted into the right to exercise this Warrant to
acquire the number of shares of stock or other securities or property (including
cash) which the Common Stock issuable (at the time of such Business Combination
or reclassification) upon exercise of this Warrant immediately prior to such
Business Combination or reclassification would have been entitled to receive
upon consummation of such Business Combination or reclassification; and in any
such case, if necessary, the provisions set forth herein with respect to the
rights and interests thereafter of the Warrantholder shall be appropriately
adjusted so as to be applicable, as nearly as may reasonably be, to the
Warrantholder's right to exercise this Warrant in exchange for any shares of
stock or other securities or property pursuant to this paragraph. In determining
the kind and amount of stock, securities or the property receivable upon
exercise of this Warrant following the consummation of such Business
Combination, if the holders of Common Stock have the right to elect the kind or
amount of consideration receivable upon consummation of such Business
Combination, then the consideration that the Warrantholder shall be entitled to
receive upon exercise shall be deemed to be the types and amounts of
consideration received by the majority of all holders of the shares of common
stock that affirmatively make an election (or of all such holders if none make
an election),

    

    
       

      (F)              Rounding of Calculations:
Minimum Adjustments, All calculations under this Section 13 shall be made
to the nearest one-tenth (1/10th) of a cent or to the nearest one- hundredth
(1/100th) of a share, as the case may be, Any provision of this Section 13 to
the contrary notwithstanding, no adjustment in the Exercise Price or the number
of Shares into which this Warrant is exercisable shall be made if the amount of
such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of
Common Stock, but any such amount shall be carried forward and an adjustment
with respect thereto shall be made at the time of and together with any
subsequent adjustment which, together with such amount and any other amount or
amounts so carried forward, shall aggregate $0.01 or 1/10th of a share of Common
Stock, or more.

    

    
       

      (G)              Timing of Issuance of
Additional Common Stock Upon Certain Adjustments. In any case in which
the provisions of this Section 13 shall require that an adjustment shall become
effective immediately after a record date for an event, the Company may defer
until the occurrence of such event (i) issuing to the Warrantholder of this
Warrant exercised after such record date and before the occurrence of such event
the additional shares of Common Stock issuable upon such exercise by reason of
the adjustment required by such event over and above the shares of Common Stock
issuable upon such exercise before giving effect to such adjustment and (ii)
paying to such Warrantholder any amount of cash in lieu of a fractional share of
Common Stock; provided,
however, that the Company upon request shall deliver to such
Warrantholder a due bill or other appropriate instrument evidencing such
Warrantholder's right to receive such additional shares, and such cash, upon the
occurrence of the event requiring such adjustment,

    

    
       

      (H)     Completion of Qualified
Equity Offering. In the event the Company (or any successor by Business
Combination) completes one or more Qualified Equity Offerings on or prior to
December 31, 2009 that result in the Company (or any such successor) receiving
aggregate gross proceeds of not less than 100% of the aggregate liquidation
preference of the Preferred Shares (and any preferred stock issued by any such
successor to the Original Warrantholder under the CPP), the number of shares of
Common Stock underlying the portion of this Warrant then held by the Original
Warrantholder shall be thereafter reduced by a number of shares of Common Stock
equal to the product of (i) 0.5 and (ii) the number of shares underlying the
Warrant on the Issue Date (adjusted to take into account all other theretofore
made adjustments pursuant to this Section 13).

    

    
       

      (I)        Other Events. For so
long as the Original Warrantholder holds this Warrant or any portion thereof, if
any event occurs as to which the provisions of this Section 13 are not strictly
applicable or, if strictly applicable, would not, in the good faith judgment of
the Board of Directors of the Company, fairly and adequately protect the
purchase rights of the Warrants in accordance with the essential intent and
principles of such provisions, then the Board of Directors shall make such
adjustments in the application of such provisions, in accordance with such
essential intent and principles, as shall be reasonably necessary, in the good
faith opinion of the Board of Directors, to protect such purchase rights as
aforesaid. The Exercise Price or the number of Shares into which this Warrant is
exercisable shall not be adjusted in the event of a change in the par value of
the Common Stock or a change in the jurisdiction of incorporation of the
Company.

    


    
      
         


      

      
        
        

        
          

        

      

      
         


      

    

    
       

      (J)       Statement Regarding
Adjustments. Whenever the Exercise Price or the number of Shares into
which this Warrant is exercisable shall be adjusted as provided in Section 13,
the Company shall forthwith file at the principal office of the Company a
statement showing in reasonable detail the facts requiring such adjustment and
the Exercise Price that shall be in effect and the number of Shares into which
this Warrant shall be exercisable after such adjustment, and the Company shall
also cause a copy of such statement to be sent by mail, first class postage
prepaid, to each Warrantholder at the address appearing in the Company's
records.

    

    
       

      (K)      Notice of Adjustment
Event. In the event that the Company shall propose to take any action of
the type described in this Section 13 (but only if the action of the type
described in this Section 13 would result in an adjustment in the Exercise Price
or the number of Shares into which this Warrant is exercisable or a change in
the type of securities or property to be delivered upon exercise of this
Warrant), the Company shall give notice to the Warrantholder, in the manner set
forth in Section 13(J), which notice shall specify the record date, if any, with
respect to any such action and the approximate date on which such action is to
take place. Such notice shall also set forth the facts with respect thereto as
shall be reasonably necessary to indicate the effect on the Exercise Price and
the number, kind or class of shares or other securities or property which shall
be deliverable upon exercise of this Warrant. In the case of any action which
would require the fixing of a record date, such notice shall be given at least
10 days prior to the date so fixed, and in case of all other action, such notice
shall be given at least 15 days prior to the taking of such proposed action.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of any such action.

    

    
       

      (L)       Proceedings Prior to Any
Action Requiring Adjustment. As a condition precedent to the taking of
any action which would require an adjustment pursuant to this Section 13, the
Company shall take any action which may be necessary, including obtaining
regulatory, New York Stock Exchange, NASDAQ Stock Market or other applicable
national securities exchange or stockholder approvals or exemptions, in order
that the Company may thereafter validly and legally issue as fully paid and
nonassessable all shares of Common Stock that the Warrantholder is entitled to
receive upon exercise of this Warrant pursuant to this Section
13.

    

    
      


    

    
      (M)     Adjustment Rules. Any
adjustments pursuant to this Section 13 shall be made successively whenever an
event referred to herein shall occur. If an adjustment in Exercise Price made
hereunder would reduce the Exercise Price to an amount below par value of the
Common Stock, then such adjustment in Exercise Price made hereunder shall reduce
the Exercise Price to the par value of the Common Stock.

    

    
       

      14.  Exchange. At any time
following the date on which the shares of Common Stock of the Company are no
longer listed or admitted to trading on a national securities exchange (other
than in connection with any Business Combination), the Original Warrantholder
may cause the Company to exchange all or a portion of this Warrant for an
economic interest (to be determined by the Original Warrantholder after
consultation with the Company) of the Company classified as permanent equity
under U.S. GAAP having a value equal to the Fair Market Value of the portion of
the Warrant so exchanged.  The Original Warrantholder shall calculate
any Fair Market Value required to be calculated pursuant to this Section 14,
which shall not be subject to the Appraisal Procedure.

    

    
       

      15.  No Impairment. The
Company will not, by amendment of its Charter or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
the provisions of this Warrant and in taking of all such action as may be
necessary or appropriate in order to protect the rights of the
Warrantholder.

    

    
       

      16.  Governing Law. This
Warrant will be governed by and construed in accordance with the federal law of
the United States if and to the extent such law is applicable, and otherwise in
accordance with the laws of the State of New York applicable to contracts made
and to be performed entirely within such State. Each of the Company and the
Warrantholder agrees (a) to submit to the exclusive jurisdiction and venue of
the United States District Court for the District of Columbia for any civil
action, suit or proceeding arising out of or relating to this Warrant or the
transactions contemplated hereby, and (b) that notice may be served upon the
Company at the address in Section 20 below and upon the Warrantholder at the
address for the Warrantholder set forth in the registry maintained by the
Company pursuant to Section 9 hereof. To the extent permitted by applicable law,
each of the Company and the Warrantholder hereby unconditionally waives trial by
jury in any civil legal action or proceeding relating to the Warrant or the
transactions contemplated hereby or thereby.

    


    
      
         


      

      
        
        

        
          

        

      

      
         


      

    

    
       

      17.  Binding Effect. This
Warrant shall be binding upon any successors or assigns of the
Company.

    

    
       

      18.  Amendments. This
Warrant may be amended and the observance of any term of this Warrant may be
waived only with the written consent of the Company and the
Warrantholder.

    

    
       

      19.  Prohibited Actions.
The Company agrees that it will not take any action which would entitle the
Warrantholder to an adjustment of the Exercise Price if the total number of
shares of Common Stock issuable after such action upon exercise of this Warrant,
together with all shares of Common Stock then outstanding and all shares of
Common Stock then issuable upon the exercise of all outstanding options,
warrants, conversion and other rights, would exceed the total number of shares
of Common Stock then authorized by its Charter.

    

    
       

      20.  Notices, Any notice,
request, instruction or other document to be given hereunder by any party to the
other will be in writing and will be deemed to have been duly given (a) on the
date of delivery if delivered personally, or by facsimile, upon confirmation of
receipt, or (b) on the second business day following the date of dispatch if
delivered by a recognized next day courier service. All notices hereunder shall
be delivered as set forth in Item 8 of Schedule A hereto, or pursuant to such
other instructions as may be designated in writing by the party to receive such
notice.

    

    
       

      21.  Entire Agreement.
This Warrant, the forms attached hereto and Schedule A hereto (the terms of
which are incorporated by reference herein), and the Letter Agreement (including
all documents incorporated therein), contain the entire agreement between the
parties with respect to the subject matter hereof and supersede all prior and
contemporaneous arrangements or undertakings with respect
thereto.
