   ------------------------------

                  (a) Whenever securities of the Company are to be registered
under the Securities Act (other than on a registration statement related to any
employee benefit plan, acquisition or corporate reorganization) (a "Piggyback
Registration"), the Company will: (i) promptly give to the Holder written notice
thereof (in any event within three business days after its receipt of notice of
any exercise of demand registration rights by any holder of the Company's
securities and at least 40 days prior to the filing of any registration
statement), which notice shall include a list of the jurisdictions in which the
Company intends to attempt to qualify its Common Stock under the applicable blue
sky or other state securities laws; and (ii) use its best efforts to cause to be
included in such registration under the Securities Act (and any related
qualification under blue sky laws or other compliance) and in any underwriting
involved therein, all of the Registrable Securities specified in a written
request made within 30 days after receipt of such written notice from the
Company by the Holder.

                  (b) If, in connection with a Piggyback Registration that is an
underwritten primary registration on behalf of the Company, the managing
underwriter shall impose a limitation on the number of shares of Common Stock
which may be included in the Registration Statement because, in its judgment,
such limitation is necessary to effect an orderly public distribution, then the

                                       2

<PAGE>

number of shares of Common Stock that may be included in such Registration
Statement shall be apportioned in the following priority: (i) first, the shares
of Common Stock the Company proposes to sell under the Registration Statement;
(ii) second shares of Common Stock Madison Run, LLC or Madison Run Holdings, LLC
proposes to sell under the Registration Statement pursuant to registration
rights possessed by those entities as of the date hereof, (iii) third the
Registrable Securities requested to be included in such Registration Statement
by the Holder; and (iv) fourth, other shares of Common Stock requested to be
included in such Registration Statement by any other selling stockholder. The
Company shall not be required by this Section 2(b) to reduce the number of
shares of Common Stock to be offered by the Company in such Registration
Statement for any reason.

                  (c) If, in connection with a Piggyback Registration that is an
underwritten secondary registration on behalf of holders of the Company's
securities (the "Initiating Securityholders"), the managing underwriter shall
impose a limitation on the number of shares of Common Stock which may be
included in the Registration Statement because, in its judgment, such limitation
is necessary to effect an orderly public distribution, then the number of shares
of Common Stock that may be included in such Registration Statement shall be
apportioned in the following priority: (i) first, B, shares of Common Stock
Madison Run, LLC or Madison Run Holdings, LLC proposes to sell under the
Registration Statement pursuant to registration rights possessed by those
entities as of the date hereof; second, the Registrable Securities owned by the
Holder, and (iii) third, other shares of Common Stock requested to be included
in such Registration Statement by any other selling stockholder.

3. Effectiveness.
   --------------

         A Registration Statement pursuant to which any Registrable Securities
are being offered will not be deemed to have become effective unless it has been
declared effective by the SEC; provided, however, that if, after it has been
declared effective, the offering of the Registrable Securities pursuant to such
Registration Statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
Registration Statement will be deemed not to have been effective during the
period of such interference, until the offering of Registrable Securities
pursuant to such Registration Statement may legally resume. The Company will be
deemed not to have used best efforts to cause the Registration Statement to
become, or to remain, effective during the requisite period if it voluntarily
takes any action that would result in any such Registration Statement not being
declared effective or that would result in the Holder not being able to offer
and sell the Registrable Securities during that period unless such action is
required by applicable laws and regulations or currently prevailing
interpretations of the staff of the SEC. The Company shall use best efforts to
maintain the effectiveness for up to 120 days (or such shorter period of time as
the underwriters need to complete the distribution of the registered offering)
of any Registration Statement pursuant to which any of the Registrable
Securities are being offered, and from time to time will amend or supplement
such Registration Statement and the Prospectus contained therein to the extent
necessary to comply with the Securities Act and any applicable state securities
laws or regulations. The Company shall also provide the Holder with as many
copies of the Prospectus contained in any such Registration Statement as the
Holder may reasonably request.

                                       3

<PAGE>

4. Expenses of Registration.
   -------------------------

         All Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to this Agreement shall be borne by the
Company. Except as provided herein, the Holder shall pay all underwriters' fees,
discounts or commissions or transfer taxes, if any, relating to the sale or
disposition of the Holder's Registrable Securities.

5. Registration Procedures.
   ------------------------

         In the case of each registration, qualification, or compliance effected
by the Company pursuant to this Agreement, the Company will keep the Holder
advised in writing as to the initiation of each registration, qualification and
compliance and as to the completion thereof. At its expense, the Company will:

                  (a) Prepare and file with the SEC a Registration Statement
with respect to such Registrable Securities as described in Section 2 and use
its best efforts to cause such Registration Statement to become effective and to
remain effective in accordance with Section 3 (provided that at least five
business days before filing a Registration Statement or Prospectus or any
amendments or supplements thereto, the Company will furnish to the counsel
selected by the Holder copies of all such documents proposed to be filed, which
documents will be subject to the review of such counsel);

                  (b) Prepare and file with the SEC such amendments and
supplements to such Registration Statement and the Prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective and
current for a period of not less than 120 days and comply with the provisions of
the Securities Act with respect to the disposition of all securities covered by
such Registration Statement during such period in accordance with the intended
methods of disposition by the sellers thereof as set forth in such Registration
Statement;

                  (c) (i) Furnish to the Holder, and to each underwriter, if
any, without charge, such number of copies of such Registration Statement, each
amendment and supplement thereto, the Prospectus included in such Registration
Statement (including each preliminary Prospectus), and such other documents as
the Holder or underwriters may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by the Holder; and (ii) consent
to the use of the Prospectus or any amendment or supplement thereto by the
Holder of Registrable Securities included in the Registration Statement in
connection with the offering and sale of the Registrable Securities covered by
the Prospectus or any amendment or supplement thereto;

                  (d) Use its best efforts to register or qualify such
Registrable Securities under all applicable securities or blue sky laws of such
jurisdictions of the United States by the time the applicable Registration
Statement is declared effective by the SEC as the Holder and any underwriters
reasonably request in writing and do any other related acts which may be
reasonably necessary or advisable to enable the Holder and underwriters to
consummate the disposition in such jurisdictions of the Registrable Securities;
provided, however, that the Company shall not be required to (i) qualify as a
foreign corporation or as a dealer in securities in any jurisdiction where it
would not otherwise be required to qualify but for this Section 5(d), (ii) file
any general consent to service of process in any jurisdiction where it would not
otherwise be subject to such service of process, or (iii) subject itself to
taxation in any such jurisdiction if it is not then so subject;

                                       4

<PAGE>

                  (e) Notify the Holder, its counsel, and the managing
underwriters, if any, promptly, and promptly confirm such notice in writing, (i)
at any time when a Prospectus relating thereto is required to be delivered under
the Securities Act, of the happening of any event as a result of which, or the
fact that, the Prospectus included in such Registration Statement contains an
untrue statement of a material fact or omits any fact necessary to make the
statements therein not misleading, and, at the reasonable request of a majority
of the Holders, the Company will prepare a supplement or amendment to such
Prospectus so that, as thereafter delivered to the purchasers of such
Registrable Securities, such Prospectus will not contain any untrue statement of
a material fact or omit to state any fact necessary to make the statements
therein not misleading; (ii) when a Registration Statement has become effective
and when any post-effective amendments and supplements thereto become effective,
(iii) of any request by the SEC or any state securities authority for amendments
and supplements to a Registration Statement or Prospectus or for additional
information after the Registration Statement has become effective, (iv) of the
issuance by the SEC or any state securities authority of any stop order
suspending the effectiveness of a Registration Statement or the qualification of
the Registrable Securities or the initiation of any proceedings for that
purpose, (v) if, between the effective date of a Registration Statement and the
closing of any sale of Registrable Securities covered thereby, the
representations and warranties of the Company contained in any underwriting or
purchase agreement, securities sales agreement or other similar agreement, if
any, cease to be true and correct in all material respects, and (vi) the
Company's reasonable determination that a post-effective amendment to the
Registration Statement would be appropriate;

                  (f) If applicable, use its best efforts to cause all such
Registrable Securities to be listed or quoted on each securities exchange or
interdealer quotation system on which similar securities issued by the Company
are then listed or quoted;

                  (g) Provide a transfer agent for all such Registrable
Securities not later than the effective date of such Registration Statement;

                  (h) Enter into such customary agreements (including
underwriting agreements on customary terms) and take all such other actions as
the underwriter, if any, reasonably requests in order to expedite or facilitate
the disposition of such Registrable Securities;

                  (i) Obtain for delivery to the Company and the managing
underwriters, if any, with copies to the Holders of the Registrable Securities
being registered, (i) an opinion of legal counsel representing the Company in
customary form and covering such matters of the type customarily covered by
legal opinions of company counsel in public offerings as the Holders shall
reasonably request, dated on the date or dates provided for in the underwriting
agreement and (ii) a comfort letter from the Company's independent public
accountants in customary form and covering such matters of the type customarily
covered by comfort letters as the Holders shall reasonably request, dated the
effective date of the Registration Statement and brought down to the closing;

                  (j) If necessary, obtain a CUSIP number for the Registrable
Securities not later than the effective date of the Registration Statement;

                                       5

<PAGE>

                  (k) Make available for inspection by the Holder, any
underwriter participating in any disposition pursuant to such Registration
Statement and any attorney, accountant or any other agent retained by the Holder
or any such underwriter, all financial and other records, pertinent corporate
documents and properties of the Company, and cause the Company's officers,
directors and employees to supply all information reasonably requested by the
Holder, any such underwriter, attorney, accountant or agent in connection with
such Registration Statement;

                  (l) Cooperate with the Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold and not bearing any restrictive legends and registered in such names as
the Holder or the underwriters may reasonably request at least two business days
prior to the closing of any sale of Registrable Securities pursuant to such
Registration Statement;

                  (m) Upon the occurrence of any circumstance contemplated by
Section 5(e)(iii), 5(e)(iv), or 5(e)(v) hereof, use best efforts to prepare a
supplement or post-effective amendment to such Registration Statement or the
related Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered to the purchasers of
the Registrable Securities, such Prospectus will not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading; and to notify the Holder to suspend use of the Prospectus
as promptly as practicable after the occurrence of such an event, and the Holder
hereby agrees to suspend use of the Prospectus until the Company has amended or
supplemented the Prospectus to correct such misstatement or omission;

                  (n) Cooperate with each seller of Registrable Securities
covered by any Registration Statement and each underwriter, if any,
participating in the disposition of such Registrable Securities and their
respective counsel in connection with any filings required to be made with the
NASD; and

                  (o) Use best efforts to take all other steps necessary to
effect the registration of the Registrable Securities covered by a Registration
Statement contemplated hereby.

6. Indemnification and Contribution.
   ---------------------------------

                  (a) In connection with any Registration Statement, the Company
shall indemnify and hold harmless each Holder and each underwriter who
participates in an offering of the Registrable Securities, each Person, if any,
who controls any of such parties within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act and each of their respective
directors, officers, employees and agents, as follows:

                           (i) from and against any and all loss, liability,
         claim, damage and expense whatsoever, joint or several, as incurred,
         arising out of or based upon any of the following statements, omissions
         or violations (a "Violation"): (A) any untrue statement or alleged
         untrue statement of a material fact contained in any Registration
         Statement (or any amendment thereto) covering Registrable Securities,
         including all documents incorporated therein by reference, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary in order to make the statements therein,
         in the light of the circumstances under which they were made, not
         misleading; (B) any untrue statement or alleged untrue statement of a
         material fact contained in any Prospectus (including any preliminary or
         final Prospectus or any amendment or supplement thereto) or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary in order to make the statements therein,
         in the light of the circumstances under which they were made, not
         misleading; or (C) any violation or alleged violation by the Company of
         the Securities Act, the Exchange Act, any state securities law or any
         rule or regulation promulgated under the Securities Act, the Exchange
         Act or any state securities law;

                                       6

<PAGE>

                           (ii) from and against any and all loss, liability,
         claim, damage and expense whatsoever, joint or several, as incurred, to
         the extent of the aggregate amount paid in settlement of any
         litigation, or any investigation or proceeding by any court or
         governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such Violation, if such settlement is
         effected with the prior written consent of the Company, which consent
         shall not be unreasonably withheld; and

                           (iii) from and against any and all expenses
         whatsoever, as incurred (including reasonable fees and disbursements of
         counsel chosen by Holder or any underwriter (except to the extent
         otherwise expressly provided in Section 6(c) hereof)), incurred in
         investigating, preparing or defending against any litigation, or any
         investigation or proceeding by any court or governmental agency or
         body, commenced or threatened, or any claim whatsoever based upon any
         such Violation, to the extent that any such expense is not paid under
         subparagraph (i) or (ii) of this Section 6(a);

provided, however, that (i) this indemnity does not apply to any loss,
liability, claim, damage or expense to the extent arising out of a Violation
that occurs in reliance upon and in conformity with written information
furnished in writing to the Company by the Holder, or any underwriter with
respect to the Holder, as the case may be, expressly for use in a Registration
Statement (or any amendment thereto) or any Prospectus (including any
preliminary or final Prospectus or any amendment or supplement thereto) and (ii)
the Company shall not be liable to the Holder, any underwriter or controlling
Person, with respect to any untrue statement or alleged untrue statement or
omission or alleged omission in any preliminary Prospectus to the extent that
any such loss, liability, claim, damage or expense of the Holder, any
underwriter or controlling Person results from the fact that the Holder or any
underwriter, sold Registrable Securities to a Person to whom there was not sent
or given, at or prior to the written confirmation of such sale, a copy of the
final Prospectus as then amended or supplemented if the Company had previously
furnished copies thereof to the Holder or any underwriter or controlling Person
and the loss, liability, claim, damage or expense of the Holder or underwriter,
or controlling Person results from an untrue statement or omission of a material
fact contained in the preliminary Prospectus which was corrected in the final
Prospectus. Any amounts advanced by the Company to an indemnified party pursuant
to this Section 6 as a result of such losses shall be returned to the Company if
it shall be finally determined by such a court in a judgment not subject to
appeal or final review that such indemnified party was not entitled to
indemnification by the Company.

                                       7

<PAGE>

                  (b) A selling Holder agrees to indemnify and hold harmless the
Company, any underwriter and each of their respective directors, officers
(including each officer of the Company who signed the Registration Statement),
employees and agents, or any other selling Holder within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act, from and against any
and all loss, liability, claim, damage and expense whatsoever described in the
indemnity contained in Section 6(a) hereof, as incurred, but only with respect
to a Violation that occurs in reliance upon and in conformity with written
information furnished to the Company by such selling Holder with respect to such
Holder expressly for use in such Registration Statement, or any such Prospectus;
provided, however, that the obligations of any such Holder hereunder shall be
limited to the proceeds received by such Holder from the sale of Registrable
Securities contemplated herein.

                  (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party, but failure to so notify an indemnifying party
shall not relieve such indemnifying party from any liability which it may have
under this Section 6, except to the extent that it is materially prejudiced by
such failure. An indemnifying party may participate at its own expense in the
defense of such action, or, if it so elects within a reasonable time after
receipt of such notice, assume the defense of any suit brought to enforce any
such claim; but if it so elects to assume the defense, such defense shall be
conducted by counsel chosen by it and approved by the indemnified party or
parties, which approval shall not be unreasonably withheld. In the event that an
indemnifying party elects to assume the defense of any such suit and retain such
counsel, the indemnified party or parties shall bear the fees and expenses of
any additional counsel thereafter retained by such indemnified party or parties;
provided, however, that the indemnified party or parties shall have the right to
employ counsel (in addition to local counsel) to represent the indemnified party
or parties who may be subject to liability arising out of any action in respect
of which indemnity may be sought against the indemnifying party if, in the
reasonable judgment of counsel for the indemnified party or parties, there may
be legal defenses available to such indemnified party or parties which are
different from or in addition to those available to the indemnifying party, in
which event the fees and expenses of appropriate separate counsel shall be borne
by the indemnifying party. In no event shall the indemnifying parties be liable
for the fees and expenses of more than one counsel (in addition to local
counsel), separate from its own counsel, for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 6 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release in form and substance satisfactory to the
indemnified parties of each indemnified party from all liability arising out of
such litigation, investigation, proceeding or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party.

                                       8

<PAGE>

                  (d) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 6 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company and the Holder
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by such indemnity agreement incurred by the
Company and the Holder, as incurred; provided, that no Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person that was not
guilty of such fraudulent misrepresentation. As between the Company and the
Holder, such parties shall contribute to such aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by such indemnity
agreement in such proportion as shall be appropriate to reflect the relative
fault of the Company, on the one hand, and the Holder, on the other hand, with
respect to the statements or omissions which resulted in such loss, liability,
claim, damage or expense, or action in respect thereof, as well as any other
relevant equitable considerations. The relative fault of the Company, on the one
hand, and of the Holder, on the other hand, shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company, on the one hand, or by or on behalf of the
Holder, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Holder agree that it would not be just and equitable if
contribution pursuant to this Section 6 were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the relevant equitable considerations. For purposes of this Section 6, each
affiliate of the Holder, and each director, officer, employee, agent and Person,
if any, who controls a Holder or such affiliate within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as the Holder, and each director of the Company, each
officer of the Company who signed the Registration Statement, and each Person,
if any, who controls the Company within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act shall have the same rights to
contribution as the Company. In no event shall the Holder be liable for an
amount in excess of the proceeds it receives from the offering.

                  (e) The obligations of the Company and the Holders under this
Section 6 shall survive the completion of an offering of Registrable Securities
pursuant to a Registration Statement. Notwithstanding the foregoing, to the
extent that the indemnification and contribution provisions contained in the
underwriting agreement executed in connection with such Registration Statement
conflict with the foregoing provisions, the provisions in such underwriting
agreement shall control.

and as shall be required in connection with any registration, qualification, or
compliance referred to in this paragraph.

8. Suspension Rights.

    --------------------

         The Company shall have the right to postpone the filing of any

counsel to the Company, the filing of such Registration Statement would
interfere with any then currently active acquisition, financing or similar
transaction of the Company by requiring the premature disclosure of any material
non-public information or because the Company's Board of Directors determines in

stockholders for such Registration Statement to be filed.

         Nothing in this Agreement shall be construed to impose on the Company

the Public Offering the Holder will allow for restrictions on sales of its
shares pursuant to the Registration Statement for the period selected by the
managing underwriter (not to exceed 180 days in any event), including without
limitation, at a minimum, not to sell, make any short sale of, pledge, grant any
option for the purchase of or otherwise dispose of or reduce its risk of
ownership with respect to any Registrable Securities (other than those included
in the registration) or other securities of the Company without the prior
written consent of the Company or the managing underwriter, as the case may be.
Additionally, Holder agrees to execute and deliver a lock-up letter (setting
forth the above restrictions in greater detail) if requested by the managing
underwriter or the Company in connection with any offering of Registrable
Securities; provided that all members of management and all other major
stockholders are required to execute and deliver a substantially similar letter.

12. Termination of Obligations.
    ---------------------------

         The right of Holder to request inclusion in any registration pursuant
to Section 2 hereof shall terminate on the date that all shares of Registrable
Securities held or entitled to be held on conversion by such Holder may
immediately be sold without restriction (including volume limitations) under
Rule 144 promulgated under the Securities Act during any 90-day period.

13. Compliance with Rule 144.
    -------------------------

         With a view to making available to Holder the benefits of Rule 144
promulgated under the Securities Act and any other rule or regulation of the SEC
that may at any time permit Holder to sell securities of the Company to the
public without registration, the Company agrees to use its best efforts to (i)
make available to the public and to the Holder such information as will enable
Holder to make sales pursuant to Rule 144 and (ii) file with the SEC in a timely
manner all reports and other documents required of the Company under the
Exchange Act.

the parties hereto acknowledge receipt of prospectuses and/or disclosure
materials associated with the investment vehicle, either through means of
hardcopy or via access to the website associated with the investment selected by
the parties to this Escrow Agreement. The parties hereto acknowledge that they
have discussed the investment and are in agreement as to the selected
investment. Digital Fusion and Summit may provide instructions changing the
investment of the Escrow Funds (subject to applicable minimum investment
requirements) by the furnishing of a Joint Written Direction to the Escrow
Agent; provided, however, that no investment or reinvestment may be made except

months. Notwithstanding anything to the contrary contained herein, Escrow Agent

ten (10) days prior written notice to Digital Fusion and Summit specifying a
date when such resignation shall take effect. Upon any such notice of
resignation, the Representatives jointly shall appoint a successor Escrow Agent
hereunder prior to the effective date of such resignation. The retiring Escrow
Agent shall transmit all records pertaining to the Escrow Funds and shall pay
all Escrow Funds to the successor Escrow Agent, after making copies of such
records as the retiring Escrow Agent deems advisable and after deduction and
payment to the retiring Escrow Agent of all fees and expenses (including court
costs and attorneys' fees) payable to, incurred by, or expected to be incurred

and the exercise of its rights hereunder. After any retiring Escrow Agent's
resignation, the provisions of this Escrow Agreement shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was Escrow Agent
under this Escrow Agreement. Any corporation or association into which the
Escrow Agent may be merged or converted or with which it may be consolidated, or
any corporation or association to which all or substantially all of the escrow
business of the Escrow Agent's corporate trust line of business may be
transferred, shall be the Escrow Agent under this Escrow Agreement without
further act.

         Section 2.8 Liability of Escrow Agent. The Escrow Agent undertakes to
perform only such duties as are expressly set forth herein and no duties shall
be implied. The Escrow Agent shall have no liability under and no duty to
inquire as to the provisions of any agreement other than this Escrow Agreement.
The Escrow Agent shall not be liable for any action taken or omitted by it in
good faith except to the extent that a court of competent jurisdiction
determines that the Escrow Agent's gross negligence or willful misconduct was
the primary cause of any loss to Digital Fusion or Summit. Escrow Agent's sole
responsibility shall be for the safekeeping and disbursement of the Escrow Funds
in accordance with the terms of this Escrow Agreement. Escrow Agent shall have
no implied duties or obligations and shall not be charged with knowledge or
notice of any fact or circumstance not specifically set forth herein. Escrow
Agent may rely upon any notice, instruction, request or other instrument, not
only as to its due execution, validity and effectiveness, but also as to the
truth and accuracy of any information contained therein, which Escrow Agent
shall believe to be genuine and to have been signed or presented by the person
or parties purporting to sign the same. In no event shall Escrow Agent be liable
for incidental, indirect, special, consequential or punitive damages (including,
but not limited to lost profits), even if the Escrow Agent has been advised of
the likelihood of such loss or damage and regardless of the form of action.

                                       4

<PAGE>

Escrow Agent shall not be obligated to take any legal action or commence any
proceeding in connection with the Escrow Funds, any account in which Escrow
Funds are deposited, this Escrow Agreement or the Underlying Agreement, or to
appear in, prosecute or defend any such legal action or proceeding. Escrow Agent
may consult legal counsel selected by it in the event of any dispute or question
as to the construction of any of the provisions hereof or of any other agreement
or of its duties hereunder, or relating to any dispute involving any party
hereto, and shall incur no liability and shall be fully indemnified from any
liability whatsoever in acting in accordance with the opinion or instruction of
such counsel. Digital Fusion and Summit, jointly and severally, shall promptly
pay, upon demand, the reasonable fees and expenses of any such counsel.

         The Escrow Agent is authorized, in its sole discretion, to comply with
orders issued or process entered by any court with respect to the Escrow Funds,
without determination by the Escrow Agent of such court's jurisdiction in the
matter. If any portion of the Escrow Funds is at any time attached, garnished or
levied upon under any court order, or in case the payment, assignment, transfer,
conveyance or delivery of any such property shall be stayed or enjoined by any
court order, or in case any order, judgment or decree shall be made or entered
by any court affecting such property or any part thereof, then and in any such
event, the Escrow Agent is authorized, in its sole discretion, to rely upon and
comply with any such order, writ, judgment or decree which it is advised by
legal counsel selected by it is binding upon it without the need for appeal or
other action; and if the Escrow Agent complies with any such order, writ,
judgment or decree, it shall not be liable to any of the parties hereto or to
any other person or entity by reason of such compliance even though such order,
writ, judgment or decree may be subsequently reversed, modified, annulled, set
aside or vacated.

         Section 2.9 Indemnification of Escrow Agent. From and at all times
after the date of this Escrow Agreement, Digital Fusion and Summit, jointly and
severally, shall, to the fullest extent permitted by law, defend, indemnify and
hold harmless Escrow Agent and each director, officer, employee, attorney, agent
and affiliate of Escrow Agent (collectively, the "Indemnified Parties") against
any and all actions, claims (whether or not valid), losses, damages,
liabilities, costs and expenses of any kind or nature whatsoever (including
without limitation reasonable attorneys' fees, costs and expenses) incurred by
or asserted against any of the Indemnified Parties from and after the date
hereof, whether direct, indirect or consequential, as a result of or arising
from or in any way relating to any claim, demand, suit, action or proceeding
(including any inquiry or investigation) by any person, including without
limitation Digital Fusion or Summit, whether threatened or initiated, asserting
a claim for any legal or equitable remedy against any person under any statute
or regulation, including, but not limited to, any federal or state securities
laws, or under any common law or equitable cause or otherwise, arising from or
in connection with the negotiation, preparation, execution, performance or
failure of performance of this Escrow Agreement or any transactions contemplated
herein, whether or not any such Indemnified Party is a party to any such action,
proceeding, suit or the target of any such inquiry or investigation; provided,
however, that no Indemnified Party shall have the right to be indemnified
hereunder for any liability finally determined by a court of competent
jurisdiction, subject to no further appeal, to have resulted solely from the
gross negligence or willful misconduct of such Indemnified Party. Each
Indemnified Party shall, in its sole discretion, have the right to select and
employ separate counsel with respect to any action or claim brought or asserted
against it, and the reasonable fees of such counsel shall be paid upon demand by
the Digital Fusion and Summit jointly and severally. The obligations of Digital
Fusion and Summit under this Section 2.9 shall survive any termination of this
Escrow Agreement and the resignation or removal of Escrow Agent.

                                       5

<PAGE>

         The parties agree that neither the payment by Digital Fusion or Summit
of any claim by Escrow Agent for indemnification hereunder nor the disbursement
of any amounts to Escrow Agent from the Escrow Funds in respect of a claim by
Escrow Agent for indemnification shall impair, limit, modify, or affect, as
between Digital Fusion and Summit, the respective rights and obligations of
Digital Fusion, on the one hand, and Summit, on the other hand, under the
Underlying Agreement.

         Section 2.10 Fees and Expenses of Escrow Agent. Digital Fusion and
Summit shall compensate Escrow Agent for its services hereunder in accordance
with Schedule A attached hereto and, in addition, shall reimburse Escrow Agent
for all of its reasonable out-of-pocket expenses, including attorneys' fees,
travel expenses, telephone and facsimile transmission costs, postage (including
express mail and overnight delivery charges), copying charges and the like. The
additional provisions and information set forth on Schedule A are hereby
incorporated by this reference, and form a part of this Escrow Agreement. All of
the compensation and reimbursement obligations set forth in this Section 2.10
shall be payable by Digital Fusion and Summit, jointly and severally, upon
demand by Escrow Agent. The obligations of Digital Fusion and Summit under this
Section 2.10 shall survive any termination of this Escrow Agreement and the
resignation or removal of Escrow Agent. Escrow Agent is authorized to, and may,
disburse to itself from the Escrow Funds, from time to time, the amount of any
compensation and reimbursement of out-of-pocket expenses due and payable
hereunder (including any amount to which Escrow Agent or any Indemnified Party
is entitled to seek indemnification pursuant to Section 2.9 hereof). Escrow
Agent shall notify the Representatives of any disbursement from the Escrow Funds
to itself or any Indemnified Party in respect of any compensation or
reimbursement hereunder and shall furnish to the Representatives copies of all
related invoices and other statements. Digital Fusion, Summit and the
Representatives hereby grant to Escrow Agent and the Indemnified Parties a
security interest in and lien upon the Escrow Funds to secure all obligations
with respect to the right to offset the amount of any compensation or
reimbursement due any of them hereunder (including any claim for indemnification
pursuant to Section 2.9 hereof) against the Escrow Funds. If for any reason
funds in the Escrow Funds are insufficient to cover such compensation and
reimbursement, Digital Fusion and Summit shall promptly pay such amounts to
Escrow Agent or any Indemnified Party upon receipt of an itemized invoice.

         Section 2.11 Representations and Warranties; Legal Opinions. Each of
Digital Fusion and Summit respectively makes the following representations and

Escrow Agent Fees:
------------------

Annual Escrow Fee:                                   $2,500
                                                      -----

The Annual Escrow Fee is payable upon execution of the escrow documents. Annual
fees cover a full year in advance, or any part thereof, and thus are not
pro-rated in the year of termination.

The fees quoted in this schedule apply to services ordinarily rendered in the
administration of an Escrow Account and are subject to reasonable adjustment
based on final review of documents, or when the Escrow Agent is called upon to
undertake unusual duties or responsibilities, or as changes in law, procedures,
or the cost of doing business demand. Services in addition to and not
contemplated in this Agreement, including, but not limited to, document
amendments and revisions, non-standard cash and/or investment transactions,
calculations, notices and reports, and legal fees, will be billed as
extraordinary expenses.

Unless otherwise indicated, the above fees relate to the establishment of one
escrow account. Additional sub-accounts governed by the same Escrow Agreement
may incur an additional charge. Transaction costs include charges for wire
transfers, checks, internal transfers and securities transactions.

Digital Fusion: ________________________

Summit: _____________________________

Termination and Disbursement. Unless earlier terminated by the provisions of the
Escrow Agreement, the Escrow Period will terminate on January 3, 2005. Any
Escrow Funds remaining on such date shall be distributed 50% to Digital Fusion
and 50% to Summit in accordance with Section 2.4 of the Escrow Agreement.
