(each such number of shares, as adjusted from time to time,  pursuant to Section
4 hereof, is, with respect to any specific exercise of the Warrant,  referred to
herein as the "Warrant  Shares") at a price of $1.25 per share (such  price,  as
adjusted  from time to time,  pursuant to Section 4 hereof,  is, with respect to
any  specific  exercise  of the  Warrant,  referred  to herein  as the  "Warrant
Price"), subject to the provisions and upon the terms and conditions hereinafter
set forth. As used herein,  (a) the term "Common Stock" shall mean the Company's
presently authorized Common Stock, par value $.001 per share, and any stock into
or for which such Common Stock may hereafter be converted or exchanged,  (b) the
term "Date of Grant"  shall  mean  October  15,  2004,  and (c) the term  "Other
Warrants"  shall mean any warrant  issued upon  transfer or partial  exercise of

     1. Term. The purchase right represented by this Warrant is exercisable,  in
whole or in part,  at any time  after the Date of Grant (the  "Initial  Exercise
Date"). This Warrant shall expire on October 15, 2009.

     2. Exercise. Subject to Section 1 hereof, the purchase right represented by
this Warrant may be exercised by the Holder hereof, in whole or in part and from

<PAGE>

time to time after the Initial  Exercise  Date, by the surrender of this Warrant
(with the notice of exercise form attached hereto as Exhibit A duly executed) at
the  principal  office of the  Company  and by the  payment to the Company of an
amount equal to the then  applicable  Warrant Price  multiplied by the number of
Warrant Shares then being purchased.  The person or persons in whose name(s) any
certificate(s)  representing  shares  of Common  Stock  shall be  issuable  upon
exercise of this Warrant  shall be deemed to have become the Holder(s) of record
of, and shall be treated for all purposes as the record Holder(s) of, the shares
represented  thereby  (and such  shares  shall be  deemed  to have been  issued)
immediately  prior to the close of business on the date or dates upon which this
Warrant is exercised.  In the event of any exercise of the rights represented by
this  Warrant,  certificates  for the  shares  of  stock so  purchased  shall be
delivered  to the Holder  hereof as soon as possible  and in any event within 30
days after such exercise and,  unless this Warrant has been fully  exercised,  a
new Warrant representing the portion of the Warrant Shares, if any, with respect
to which this Warrant shall not then have been exercised shall also be issued to
the  Holder  hereof as soon as  possible  and in any event  within  such  30-day
period.

     3. Stock Fully Paid;  Reservation of Shares. All Warrant Shares that may be
issued upon the exercise of the rights  represented  by this Warrant will,  upon
issuance  pursuant  to the  terms  and  conditions  herein,  be  fully  paid and

respect  to, or based  upon,  the income of the  person to whom such  shares are
issued),  liens and charges  (other than liens or charges  created by actions of
the Holder of this  Warrant or the person to whom such shares are  issued),  and
pre-emptive  rights with respect to the issue thereof.  During the period within
which the rights represented by this Warrant may be exercised,  the Company will
at all times have  authorized,  and  reserved  for the purpose of the issue upon
exercise of the purchase rights evidenced by this Warrant,  a sufficient  number
of  shares  of its  Common  Stock to  provide  for the  exercise  of the  rights
represented by this Warrant.

     4. Adjustment of Warrant Price and Number of Shares. The number and kind of
securities  purchasable  upon the exercise of this Warrant and the Warrant Price
shall be subject to adjustment  from time to time upon the occurrence of certain
events, as follows:

     a. Reclassification or Merger. In case of any  reclassification,  change or
     conversion  of  securities  of the class  issuable  upon  exercise  of this
     Warrant  (other  than a change  in par  value,  or from par value to no par
     value,  or from no par value to par value,  or as a result of a subdivision
     or  combination),  or in case of any  merger  of the  Company  with or into
     another  corporation (other than a merger with another corporation in which
     the Company is the acquiring and the surviving  corporation  and which does
     not  result in any  reclassification  or change of  outstanding  securities
     issuable upon exercise of this  Warrant),  or in case of any sale of all or
     substantially  all of the  assets  of the  Company,  the  Company,  or such
     successor or purchasing corporation, as the case may be, shall duly execute

                                      -2-
<PAGE>

     and  deliver  to the  Holder  of this  Warrant a new  Warrant  (in form and
     substance  satisfactory to the Holder of this Warrant),  so that the Holder
     of this Warrant shall have the right to receive,  at a total purchase price
     not to exceed that payable upon the exercise of the unexercised  portion of
     this  Warrant,  and in lieu  of the  shares  of  Common  Stock  theretofore
     issuable upon  exercise of this  Warrant,  the kind and amount of shares of
     stock,   other  securities,   money  and  property   receivable  upon  such
     reclassification,  change or merger by a Holder of the  number of shares of
     Common Stock (or similar  security)  then  purchasable  under this Warrant.
     Such new  Warrant  shall  provide for  adjustments  that shall be as nearly
     equivalent as may be  practicable to the  adjustments  provided for in this
     Section 4. The  provisions of this Section 4.a.  shall  similarly  apply to
     successive reclassifications, changes, mergers and transfers.

     b. Subdivision or Combination of Shares.  If at any time while this Warrant
     remains  outstanding  and unexpired the Company shall  subdivide or combine
     its  outstanding  shares  of  common  stock,  the  Warrant  Price  shall be
     proportionately  decreased  and  the  number  of  Warrant  Shares  issuable
     hereunder shall be  proportionately  increased in the case of a subdivision
     and the Warrant Price shall be  proportionately  increased in the case of a
     combination  and the number of Warrant Shares  issuable  hereunder shall be
     proportionately  decreased,  effective at the close of business on the date
     the subdivision or combination becomes effective.

     c. Stock  Dividends.  If at any time while this Warrant is outstanding  and
     unexpired the Company shall (i) pay a dividend with respect to Common Stock
     payable in Common Stock, then the Warrant Price shall be adjusted, from and
     after the date of  determination  of stockholders  entitled to receive such
     dividend or  distribution,  to that price  determined  by  multiplying  the
     Warrant Price in effect  immediately prior to such date of determination by
     a fraction  (A) the  numerator of which shall be the total number of shares
     of Common Stock outstanding immediately prior to such dividend, and (B) the
     denominator  of which shall be the total  number of shares of Common  Stock
     outstanding immediately after such dividend or (ii) make any other dividend
     or  distribution  with  respect to Common  Stock  (except any  distribution
     specifically  provided for in Sections  4.a. and 4.b.),  then,  the Company
     will provide notice to the Investor of such dividend or  distribution  with
     respect to the Common Stock and, if the Warrant is exercised in whole or in
     part  within five days of actual  receipt by the  Investor of the notice of
     such  dividend or  distribution,  the Holder of the shares of Common  Stock
     acquired  pursuant  to such  exercise  shall be  entitled  to  receive  the
     dividend or distribution with respect to the Warrant Shares acquired by the
     Investor upon such exercise of the Warrant.

     5.  Notice of  Adjustments.  Whenever  the  Warrant  Price or the number of
Warrant Shares  purchasable  hereunder  shall be adjusted  pursuant to Section 4
hereof,  the Company  shall  deliver to the Holder of this Warrant a certificate
signed by a duly designated  officer of the Company setting forth, in reasonable

                                      -3-
<PAGE>

detail,  the event requiring the adjustment,  the amount of the adjustment,  the
method by which such  adjustment was  calculated,  and the Warrant Price and the
number of Warrant  Shares  purchasable  hereunder  after  giving  effect to such
adjustment.

     6. Dividends. In the event that the Company shall fix a record date for the
making of any stock  dividend  to  Holders of shares of its  Common  Stock,  the
Company shall notify the Holder of the Warrants, in writing, at least 30 days in
advance of the record date for the proposed dividend or distribution.

     7. Fractional  Shares.  No fractional shares of Common Stock will be issued
in connection with any exercise hereunder, but in lieu of such fractional shares
the Company  shall round up the shares to which the recipient is entitled to the
nearest whole share.

     Company is disposed  of, the Company  will  provide at least 30 days notice

                                   ----------

                       INVESTMENT REPRESENTATION STATEMENT

Purchaser:
Company:        DIGITAL FUSION, INC.
Security:       Common Stock

Amount:
Date:

     In  connection  with  the  purchase  of the  above-listed  securities  (the
"Securities"),  the undersigned (the  "Purchaser")  represents to the Company as
follows:

     (a) The Purchaser is aware of the Company's  business affairs and financial
condition, and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  The Purchaser is
purchasing the  Securities for its own account for investment  purposes only and
not with a view to, or for the resale in  connection  with,  any  "distribution"
thereof for purposes of the Securities Act of 1933, as amended (the "Act").

     (b) The Purchaser  understands that the Securities have not been registered
under the Securities Act in reliance upon a specific exemption therefrom,  which
exemption  depends  upon,  among  other  things,  the bona  fide  nature  of the
Purchaser's  investment  intent as expressed  herein.  In this  connection,  the
Purchaser  understands  that,  in  the  view  of  the  Securities  and  Exchange
Commission ("SEC"), the statutory basis for such exemption may be unavailable if
the Purchaser's representation was predicated solely upon a present intention to
hold these  Securities  for the minimum  capital  gains period  specified  under
applicable  tax laws,  for a deferred sale, for or until an increase or decrease
in the market price of the Securities,  or for a period of one year or any other
fixed period in the future.

     (c) The Purchaser  further  understands  that the  Securities  must be held
indefinitely unless  subsequently  registered under the Securities Act or unless
an  exemption  from  registration  is  otherwise  available.  In  addition,  the
Purchaser  understands  that the  certificate  evidencing the Securities will be
imprinted with the legend  referred to in the Warrant under which the Securities
are being purchased.

     (d)  The  Purchaser  is  aware  of the  provisions  of Rule  144 and  144A,
promulgated under the Securities Act, which, in substance, permit limited public

<PAGE>

resale of "restricted  securities"  acquired,  directly or indirectly,  from the
issuer thereof (or from an affiliate of such issuer),  in a non-public  offering
subject to the  satisfaction of certain  conditions,  if applicable,  including,
among other things:  The  availability of certain public  information  about the
Company,  the  resale  occurring  not less than one (1) year after the party has
purchased and paid for the  securities to be sold; the sale being made through a
broker in an unsolicited "broker's transaction" or in transactions directly with
a market  maker (as said term is defined  under the  Securities  Exchange Act of
1934, as amended) and the amount of securities being sold during any three-month
period not exceeding the specified limitations stated therein.

     (e) The Purchaser  further  understands  that at the time it wishes to sell
the Securities there may be no public market upon which to make such a sale, and
that,  even  if  such a  public  market  then  exists,  the  Company  may not be
satisfying the current public information requirements of Rule 144 and 144A, and
that, in such event,  the Purchaser may be precluded from selling the Securities
under Rule 144 and 144A even if the  one-year  minimum  holding  period had been
satisfied.

     (f)  The  Purchaser  further  understands  that  in  the  event  all of the
requirements  of Rule 144 and 144A are not  satisfied,  registration  under  the
Securities  Act,  compliance  with  Regulation  A,  or some  other  registration
exemption will be required; and that,  notwithstanding the fact that Rule 144 is
not  exclusive,  the Staff of the SEC has  expressed  its opinion  that  persons
proposing  to sell  private  placement  securities  other  than in a  registered
offering and otherwise than pursuant to Rule 144 will have a substantial  burden
of proof in  establishing  that an exemption from  registration is available for
such offers or sales,  and that such  persons and their  respective  brokers who
participate in such transactions do so at their own risk.

                                        Purchaser:
                                                  -----------------------------
                                        Date:
                                             ----------------------------------
