    “Appraisal Procedure” means a
procedure whereby two independent appraisers, one chosen by the Company and one
by the Original Warrantholder, shall mutually agree upon the determinations then
the subject of appraisal. Each party shall deliver a notice to the other

invoked. If within 30 days after appointment of the two appraisers they are
unable to agree upon the amount in question, a third independent appraiser shall
be chosen within 10 days thereafter by the mutual consent of such first two
appraisers.  The decision of the third appraiser so appointed and
chosen shall be given within 30 days after the selection of such third
appraiser. If three appraisers shall be appointed and the determination of one
appraiser is disparate from the middle determination by more than twice the
amount by which the other determination is disparate from the middle
determination, then the determination of such appraiser shall be excluded, the
remaining two determinations shall be averaged and such average shall be binding
and conclusive upon the Company and the Original Warrantholder; otherwise, the
average of all three determinations shall be binding upon the Company and the
Original Warrantholder. The costs of conducting any Appraisal Procedure shall be
borne by the Company.

the Company on the date hereof, but in no event later than 5:00 p.m., New York
City time on the tenth anniversary of the Issue Date (the “Expiration Time”), by (A)
the surrender of this Warrant and Notice of Exercise annexed hereto, duly

will be entitled to receive from the Company within a reasonable time, and in
any event not exceeding three business days, a new warrant in substantially
identical form for the purchase of that number of Shares equal to the difference
between the number of Shares subject to this Warrant and the number of Shares as

to the contrary, the Warrantholder hereby acknowledges and agrees that its
exercise of this Warrant for Shares is subject to the condition that the
Warrantholder will have first received any applicable Regulatory
Approvals.

exercise of this Warrant will be issued in such name or names as the
Warrantholder may designate and will be delivered to such named Person or
Persons within a reasonable time, not to exceed three business days after the
date on which this Warrant has been duly exercised in accordance with the terms
of this Warrant. The Company hereby represents and warrants that any Shares
issued upon the exercise of this Warrant in accordance with the provisions of
Section 3 will be duly and validly authorized and issued, fully paid and
nonassessable and free from all taxes, liens and charges (other than liens or
charges created by the Warrantholder, income and franchise taxes incurred in
connection with the exercise of the Warrant or taxes in respect of any transfer
occurring contemporaneously therewith). The Company agrees that the Shares so
issued will be deemed to have been issued to the Warrantholder as of the close
of business on the date on which this Warrant and payment of the Exercise Price
are delivered to the Company in accordance with the terms of this Warrant,
notwithstanding that the stock transfer books of the Company may then be closed
or certificates representing such Shares may not be actually delivered on such
date. The Company will at all times reserve and keep available, out of its
authorized but unissued Common Stock, solely for the purpose of providing for
the exercise of this Warrant, the aggregate number of shares of Common Stock
then issuable upon exercise of this Warrant at any time. The Company will (A)
procure, at its sole expense, the listing of the Shares issuable upon exercise
of this Warrant at any time, subject to issuance or notice of issuance, on all
principal stock exchanges on which the Common Stock is then listed or traded and
(B) maintain such listings of such Shares at all times after issuance. The
Company will use reasonable best efforts to ensure that the Shares may be issued
without violation of any applicable law or regulation or of any requirement of
any securities exchange on which the Shares are listed or traded.

     

    5. No Fractional Shares or
Scrip.  No fractional Shares or scrip representing fractional
Shares shall be issued upon any exercise of this Warrant. In lieu of any
fractional Share to which the Warrantholder would otherwise be entitled, the
Warrantholder shall be entitled to receive a cash payment equal to the Market
Price of the Common Stock on the last trading day preceding the date of exercise
less the pro-rated Exercise Price for such fractional share.

     

    6. No Rights as Stockholders;
Transfer Books.  This Warrant does not entitle the
Warrantholder to any voting rights or other rights as a stockholder of the
Company prior to the date of exercise hereof. The Company will at no time close
its transfer books against transfer of this Warrant in any manner which
interferes with the timely exercise of this Warrant

     

    7. Charges, Taxes and
Expenses.  Issuance of certificates for Shares to the
Warrantholder upon the exercise of this Warrant shall be made without charge to
the Warrantholder for any issue or transfer tax or other incidental expense in

shall be paid by the Company.

    (A) Subject
to compliance with clause (B) of this Section 8, this Warrant and all rights
hereunder are transferable, in whole or in part, upon the books of the Company

surrender of this Warrant, duly endorsed, to the office or agency of the Company
described in Section 3. All expenses (other than stock transfer taxes) and other
charges payable in connection with the preparation, execution and delivery of
the new warrants pursuant to this Section 8 shall be paid by the
Company.

     

    (B) The
transfer of the Warrant and the Shares issued upon exercise of the Warrant are
subject to the restrictions set forth in Section 4.4 of the Purchase Agreement.
If and for so long as required by the Purchase Agreement, this Warrant shall
contain the legends as set forth in Sections 4.2(a) and 4.2(b) of the Purchase
Agreement.

     

    9. Exchange and Registry of
Warrant.  This Warrant is exchangeable, upon the surrender
hereof by the Warrantholder to the Company, for a new warrant or warrants of
like tenor and representing the right to purchase the same aggregate number of
Shares. The Company shall maintain a registry showing the name and address of
the Warrantholder as the registered holder of this Warrant. This Warrant may be
surrendered for exchange or exercise in accordance with its terms, at the office
of the Company, and the Company shall be entitled to rely in all respects, prior
to written notice to the contrary, upon such registry.

     

    10. Loss, Theft, Destruction or
Mutilation of Warrant.  Upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and in the case of any such loss, theft or destruction, upon
receipt of a bond, indemnity or security reasonably satisfactory to the Company,
or, in the case of any such mutilation, upon surrender and cancellation of this
Warrant, the Company shall make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same aggregate number of Shares as provided for in such
lost, stolen, destroyed or mutilated Warrant.

     

    11. Saturdays, Sundays,
Holidays, etc.  If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall not
be a business day, then such action may be taken or such right may be exercised
on the next succeeding day that is a business day.

     

    12. Rule 144
Information.  The Company covenants that it will use its
reasonable best efforts to timely file all reports and other documents required
to be filed by it under the Securities Act and the Exchange Act and the rules
and regulations promulgated by the SEC thereunder (or, if the Company is not
required to file such reports, it will, upon the request of any Warrantholder,
make publicly available such information as necessary to permit sales pursuant
to Rule 144 under the Securities Act), and it will use reasonable best efforts
to take such further action as any Warrantholder may reasonably request, in each
case to the extent required from time to time to enable such holder to, if
permitted by the terms of this Warrant and the Purchase Agreement, sell this
Warrant without registration under the Securities Act within the limitation of
the exemptions provided by (A) Rule 144 under the Securities Act, as such rule
may be amended from time to time, or (B) any successor rule or regulation
hereafter adopted by the SEC. Upon the written request of any Warrantholder, the
Company will deliver to such Warrantholder a written statement that it has
complied with such requirements.

    13. Adjustments and Other
Rights.  The Exercise Price and the number of Shares issuable
upon exercise of this Warrant shall be subject to adjustment from time to time
as follows; provided,
that if more than one subsection of this Section 13 is applicable to a
single event, the subsection shall be applied that produces the largest
adjustment and no single event shall cause an adjustment under more than one
subsection of this Section 13 so as to result in duplication:

     

    (A) Stock Splits, Subdivisions,
Reclassifications or Combinations.  If the Company shall (i)
declare and pay a dividend or make a distribution on its Common Stock in shares
of Common Stock, (ii) subdivide or reclassify the outstanding shares of Common
Stock into a greater number of shares, or (iii) combine or reclassify the
outstanding 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 which the Original Warrantholder no longer holds this Warrant or any
portion 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
exercisable or convertible into or exchangeable (collectively, a “conversion”)
for shares of Common Stock) (collectively, “convertible
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

     

    
      
        
        

      

      
        8

        
          

        

      

      
        
        

      

    

    (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.
