     4.1 Organization, Good Standing and Qualification. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. The Company has the corporate power and authority to
own and operate its properties and assets, to execute and deliver this

and all other agreements referred to herein (collectively, the "Related
Agreements"), to issue and sell the Note and the shares of Common Stock issuable
upon conversion of the Note (the "Note Shares") (in the case of the Company


                                       2


only), to issue and sell the Warrant and the Warrant Shares (in the case of the
Company only), and to carry out the provisions of this Agreement and the Related
Agreements and to carry on its business as presently conducted. The Company is
duly qualified and is authorized to do business and is in good standing as a
foreign corporation in all jurisdictions in which the nature of its activities
and of its properties (both owned and leased) makes such qualification

anti-dilution or other similar provisions contained in or affecting any such
securities.

     (c) All issued and outstanding shares of the Company's Common Stock (i)
have been duly authorized and validly issued and are fully paid and

provided, however, that the Securities may be subject to restrictions on
transfer under state and/or federal securities laws as set forth herein or as
otherwise required by such laws at the time a transfer is proposed.

Shares are not and will not be subject to any preemptive rights or rights of

or of any judgment, decree, order or writ. The execution, delivery and
performance of and compliance with this Agreement and the Related Agreements to
which it is a party, and the issuance and sale of the Note by the Company and
the other Securities by the Company each pursuant hereto, will not, with or
without the passage of time or giving of notice, result in any such material

or prospects of the Company, financially or otherwise, or any change in the
current equity ownership of the Company, nor is the Company aware that there is
any basis for any of the foregoing. The Company is not a party or subject to the

by the Company; and to the Company's knowledge the continued employment by the
Company of its present employees, and the performance of the Company's contracts
with its independent contractors, will not result in any such violation. The
Company is not aware that any of its employees is obligated under any contract
(including licenses, covenants or commitments of any nature) or other agreement,
or subject to any judgment, decree or order of any court or administrative

     4.18 Valid Offering. Assuming the accuracy of the representations and
warranties of the Purchaser contained in this Agreement, the offer, sale and
issuance of the Securities will be exempt from the registration requirements of
the Securities Act of 1933, as amended (the "Securities Act"), and will have
been registered or qualified (or are exempt from registration and qualification)
under the registration, permit or qualification requirements of all applicable
state securities laws.

     4.19 Full Disclosure. The Company has provided the Purchaser with all
information requested by the Purchaser in connection with its decision to

reasonably necessary to make such investment decision. Neither this Agreement,
the exhibits and schedules hereto, the Related Agreements nor any other document
delivered by the Company to Purchaser or its attorneys or agents in connection
herewith or therewith or with the transactions contemplated hereby or thereby,
contain any untrue statement of a material fact nor omit to state a material
fact necessary in order to make the statements contained herein or therein, in
light of the circumstances in which they are made, not misleading. Any financial
projections and other estimates provided to the Purchaser by the Company were
based on the Company's experience in the industry and on assumptions of fact and
opinion as to future events which the Company, at the date of the issuance of
such projections or estimates, believed to be reasonable. As of the date hereof
the Company has seen no material improvement in Information Technology (IT)
spending by its clients and prospects that underlies and drives its revenue
projections. The Company is not likely to meet or exceed financial projections
provided to the Purchaser until IT spending and the general United States
economy improves. As of the date hereof and until IT spending improves the
operational plan of the Company is to retain core clients, tactically engage new
clients with small transactions and manage cash burn (primarily through
controlling costs). The Company anticipates that it will remain cash flow
negative to cash flow neutral for the foreseeable future.

the notes thereto) included in the SEC Reports, as of their respective filing
dates, contained any untrue statement of a material fact or omitted to state a

therein, in light of the circumstances under which they were made, not
misleading.

affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any security or solicited any offers to
buy any security under circumstances that would cause the offering of the
Securities pursuant to this Agreement to be integrated with prior offerings by
the Company for purposes of the Securities Act which would prevent the Company
from selling the Securities pursuant to Rule 506 under the Securities Act, or
any applicable exchange-related stockholder approval provisions. Nor will the
Company or any of its affiliates or subsidiaries take any action or steps that
would cause the offering of the Securities to be integrated with other
offerings.

     4.24 Stop Transfer. The Securities are restricted securities as of the date
of this Agreement. The Company will not issue any stop transfer order or other
order impeding the sale and delivery of any of the Securities at such time as

harmless, reimburse and defend the Company and each of the Company's officers,
directors, agents, affiliates, control persons and principal shareholders, at
all times against any claim, cost, expense, liability, obligation, loss or

     8.3 Procedures. The procedures and limitations set forth in Section 10.6
shall apply to the indemnifications set forth in Sections 8.1 and 8.2 above.

     9. CONVERSION OF CONVERTIBLE NOTE.

     9.1 Mechanics of Conversion.

     (a) Provided the Purchaser has notified the Company of the Purchaser's
intention to sell the Note Shares and the Note Shares are included in an
effective registration statement or are otherwise exempt from registration when
sold: (i) Upon the conversion of the Note or part thereof, the Company shall, at
its own cost and expense, take all necessary action (including the issuance of
an opinion of counsel) to assure that the Company's transfer agent shall issue
shares of the Company's Common Stock in the name of the Purchaser (or its
nominee) or such other persons as designated by the Purchaser in accordance with
Section 9.1(b) hereof and in such denominations to be specified representing the
number of Note Shares issuable upon such conversion; and (ii) The Company
warrants that no instructions other than these instructions have been or will be
given to the transfer agent of the Company's Common Stock and that after the
Effective Date (as hereinafter defined) the Note Shares issued will be freely
transferable subject to the prospectus delivery requirements of the Securities
Act and the provisions of this Agreement, and will not contain a legend
restricting the resale or transferability of the Note Shares.

     (b) Purchaser will give notice of its decision to exercise its right to
convert the Note or part thereof by telecopying or otherwise delivering an
executed and completed notice of the number of shares to be converted to the
Company (the "Notice of Conversion"). The Purchaser will not be required to
surrender the Note until the Purchaser receives a credit to the account of the
Purchaser's prime broker through the DWAC system (as defined below),
representing the Note Shares or until the Note has been fully satisfied. Each
date on which a Notice of Conversion is telecopied or delivered to the Company
in accordance with the provisions hereof shall be deemed a "Conversion Date."
The Company will cause the transfer agent to transmit the shares of the
Company's Common Stock issuable upon conversion of the Note (and a certificate
representing the balance of the Note not so converted, if requested by
Purchaser) to the Purchaser by crediting the account of the Purchaser's prime
broker with the Depository Trust Company ("DTC") through its Deposit Withdrawal
Agent Commission ("DWAC") system within five (5) business days after receipt by
the Company of the Notice of Conversion (the "Delivery Date").


                                       16


     The Company understands that a delay in the delivery of the Note Shares in
the form required pursuant to Section 9 hereof beyond the Delivery Date could
result in economic loss to the Purchaser. In the event that the Company fails to
direct its transfer agent to deliver the Note Shares to the Purchaser via the
DWAC system within the time frame set forth in Section 9.1(b) above and the Note
Shares are not delivered to the Purchaser by the Delivery Date, as compensation
to the Purchaser for such loss, the Company agrees to pay late payments to the
Purchaser for late issuance of the Note Shares in the form required pursuant to
Section 9 hereof upon conversion of the Note in the amount equal to the greater
of (i) $500 per business day after the Delivery Date or (ii) the Purchaser's
actual damages from such delayed delivery. Notwithstanding the foregoing, the
Company will not owe the Purchaser any late payments if the delay in the
delivery of the Note Shares beyond the Delivery Date is solely out of the
control of the Company and the Company is actively trying to cure the cause of
the delay. The Company shall pay any payments incurred under this Section in
immediately available funds upon demand and, in the case of actual damages,
accompanied by reasonable documentation of the amount of such damages. Such
documentation shall show the number of shares of Common Stock the Purchaser is
forced to purchase (in an open market transaction) which the Purchaser
anticipated receiving upon such conversion, and shall be calculated as the
amount by which (A) the Purchaser's total purchase price (including customary
brokerage commissions, if any) for the shares of Common Stock so purchased
exceeds (B) the aggregate principal and/or interest amount of the Note, for
which such Conversion Notice was not timely honored.


     Nothing contained herein or in any document referred to herein or delivered
in connection herewith shall be deemed to establish or require the payment of a
rate of interest or other charges in excess of the maximum permitted by
applicable law. In the event that the rate of interest or dividends required to
be paid or other charges hereunder exceed the maximum amount permitted by such
law, any payments in excess of such maximum shall be credited against amounts
owed by the Company to a Purchaser and thus refunded to the Company.

     9.2 Maximum Conversion. The Purchaser shall not be entitled to convert on a
Conversion Date that amount of a Note in connection with that number of shares
of Common Stock which would be in excess of the sum of (i) the number of shares
of Common Stock beneficially owned by the Purchaser on a Conversion Date, and
(ii) the number of shares of Common Stock issuable upon the conversion of the
Note with respect to which the determination of this proviso is being made on a
Conversion Date, which would result in beneficial ownership by the Purchaser of
more than 4.9% of the outstanding shares of Common Stock of the Company on such
Conversion Date. For the purposes of the immediately preceding sentence,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Exchange Act and Regulation 13d-3 thereunder. Upon an Event of Default under the
Note, the conversion limitation in this Section 9.2 shall become null and void.

     9.3 Optional Redemption. The Company will have the option of redeeming any
outstanding principal of the Note ("Optional Redemption") by paying to the
Purchaser a sum of money equal to 110% of such principal amount being redeemed
(this number shall be 100% after 210 days from the date hereof), together with
accrued but unpaid interest thereon and any and all other sums due, accrued or
payable to the Purchaser arising under this Agreement, Note or any other
document delivered herewith ("Redemption Amount") outstanding on the day notice


                                       17


of redemption ("Notice of Redemption") is delivered to a Purchaser ("Redemption
Date"). A Notice of Redemption may not be given in connection with any portion
of Note for which a Notice of Conversion has been given by the Purchaser at any
time before receipt of a Notice of Redemption or given pursuant to the following
sentence. A Notice of Redemption must be accompanied by a certificate signed by
the chief executive officer or chief financial officer of the Company stating
that the Company has on deposit and segregated ready funds equal to the
Redemption Amount. The Redemption Amount must be paid in good funds to the
Purchaser no later than the seventh (7th) business day after the Redemption Date
("Optional Redemption Payment Date"). In the event the Company fails to pay the
Redemption Amount by the Optional Redemption Payment Date, then the Redemption
Notice will be null and void. A Notice of Redemption may be given by the
Company, provided (i) no Event of Default as described in the Note shall have
occurred or be continuing; and (ii) the Note Shares issuable upon conversion of
the full outstanding Note principal are included for unrestricted resale in a
registration statement effective as of the Redemption Date

     10. REGISTRATION RIGHTS.

     10.1 Registration Rights Granted. The Company hereby grants the following
registration rights to the Purchaser:

     (a) If the Company at any time proposes to register any of its securities
under the Act for sale to the public, whether for its own account or for the
account of other security holders or both, except with respect to registration
statements on Forms S-4, S-8 or another form not available for registering the
Registrable Securities for sale to the public, provided the Registrable
Securities are not otherwise subject to an effective registration statement, the
Company will give the Purchaser written notice ("Notice of Registration") to
cause such Registrable Securities to be included with the securities to be
covered by the registration statement proposed to be filed by the Company. In
the event that any registration pursuant to this Section 10.1(a) shall be, in
whole or in part, an underwritten public offering of Common Stock of the
Company, the number of shares of Registrable Securities to be included in such
an underwriting may be reduced by the managing underwriter if and to the extent
that the Company and the underwriter shall reasonably be of the opinion that
such inclusion would adversely affect the marketing of the securities to be sold
by the Company therein; provided, however, that the Company shall notify the
Purchaser in writing of any such reduction.

     (b) The Company shall use its reasonable commercial efforts to file a Form
S-3 registration statement (or such other form that it is eligible to use) in
order to register the issuance of the Registrable Securities to the Purchaser
under the Securities Act with the SEC within 30 days of the Purchaser providing
written notice to the Company; provided, however, that the Purchaser will not
provide such notice until there remains less than 20% of the original amount of
securities registered on the Company's registration statement, file no.
333-100052 (the "Filing Date"), and use its reasonable commercial efforts to
cause such registration statement to be declared effective within 90 days of the
Filing Date (the "Effective Date"). The Company will register a number of shares
of Common Stock in the aforedescribed registration statement that is equal to
the Warrant Shares and 100% of the Note Shares issuable at the Fixed Conversion
Price set forth in the Note, that would be in effect on the Closing Date,
assuming the conversion of 100% of the principal amount of the Note which is
then outstanding, and at least one share of Common Stock for each common share
issuable upon exercise of the Warrant, plus interest payable under the Note;
provided, however, that the Company will not be required to register a number of
shares greater than 19.9% of the Company's total outstanding shares of Common
Stock as of the date hereof ("Registrable Securities").


                                       18


     10.2 Registration Procedures. If and whenever the Company is required by
the provisions hereof to effect the registration of the Registrable Securities
under the Act, the Company will:

     (a) prepare and file with the SEC a registration statement with respect to
such securities and use its best efforts to cause such registration statement to
become and remain effective for the period of the distribution contemplated
thereby (determined as herein provided), and promptly provide to the Purchaser
copies of all filings and SEC letters of comment;

     (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 until the earlier of:
(i) six months after the latest exercise period of the Warrant; (ii) four years
after the Closing Date, or (iii) the date on which the Purchaser has disposed of
all of the Registrable Securities covered by such registration statement in
accordance with the Purchaser's intended method of disposition set forth in such
registration statement for such period;

     (c) furnish to the Purchaser such number of copies of the registration
statement and the prospectus included therein (including each preliminary
prospectus) as the Purchaser reasonably may request to facilitate the public
sale or disposition of the securities covered by such registration statement;

     (d) use its commercially reasonable efforts to register or qualify the
Purchaser's Registrable Securities covered by such registration statement under
the securities or "blue sky" laws of such jurisdictions as the Purchaser,
provided, however, that the Company shall not for any such purpose be required
to qualify generally to transact business as a foreign corporation in any
jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction;

     (e) list the Registrable Securities covered by such registration statement
with any securities exchange on which the Common Stock of the Company is then
listed;

     (f) immediately notify the Purchaser at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, of the happening
of any event of which the Company has knowledge as a result of which the
prospectus contained in such registration statement, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing; and

     (g) make available for inspection by the Purchaser and any attorney,
accountant or other agent retained by the Purchaser, all publicly available,
non-confidential financial and other records, pertinent corporate documents and
properties of the Company, and cause the Company's officers, directors and
employees to supply all publicly available, non-confidential information
reasonably requested by the attorney, accountant or agent of the Purchaser.


                                       19


     10.3 Provision of Documents. In connection with the registration hereunder,
the Purchaser will furnish to the Company in writing such information and
representation letters with respect to itself and the proposed distribution by
it as reasonably shall be necessary in order to assure compliance with federal
and applicable state securities laws.

     10.4 Non-Registration Events.

     If (i) the Registration Statement described in Section 10.1(b) is not filed
on or before the Filing Date or not declared effective on or before the sooner
of the Effective Date, or within four business days of receipt by the Company of
a communication from the SEC that the registration statement described in
Section 10.1(b) will not be reviewed, or (ii) any registration statement
described in Section 10.1(b) is filed and declared effective but shall
thereafter cease to be effective (without being succeeded immediately by an
additional registration statement filed and declared effective) for a period of
time which shall exceed 30 days in the aggregate per year but not more than 20
consecutive calendar days (defined as a period of 365 days commencing on the
date the Registration Statement is declared effective) (each such event referred
to in this Section 10.4 is referred to herein as a "Non-Registration Event"),
the Purchaser, at its sole option, may declare in a written notice to the
Company that the Non-Registration Event has triggered an Event of Default (as
defined in Article IV of the Note.) Declaring an Event of Default under the Note
is the Purchaser's sole remedy for a Non-Registration Event.

     10.5 Expenses. All expenses incurred by the Company in complying with
Section 10, including, without limitation, all registration and filing fees,
printing expenses, fees and disbursements of counsel and independent public
accountants for the Company, fees and expenses (including reasonable counsel
fees) incurred in connection with complying with state securities or "blue sky"
laws, fees of the NASD, transfer taxes, fees of transfer agents and registrars,
fees of, and disbursements incurred by, and costs of insurance are called
"Registration Expenses". All underwriting discounts and selling commissions
applicable to the sale of Registrable Securities, including any fees and
disbursements of any special counsel to the Purchaser beyond those included in
Registration Expenses, are called "Selling Expenses." The Company will pay all
Registration Expenses. All Selling Expenses in connection with each registration
statement under Section 10 shall be borne by the Purchaser.

     10.6 Indemnification.

     (a) In the event of a registration of any Registrable Securities under the
Securities Act pursuant to Section 10, the Company will indemnify and hold
harmless the Purchaser, and its officers, directors and each other person, if
any, who controls the Purchaser within the meaning of the Securities Act,
against any losses, claims, damages or liabilities, joint or several, to which
the Purchaser, or such persons may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Registrable Securities were registered under the Securities Act
pursuant to Section 10, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse the Purchaser, and each such person for any reasonable legal
or other expenses incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished by the Purchaser or any such person in
writing specifically for use in any such document.


                                       20


     (b) In the event of a registration of the Registrable Securities under the
Securities Act pursuant to Section 10, the Purchaser will indemnify and hold
harmless the Company, and its officers, directors and each other person, if any,
who controls the Company within the meaning of the Securities Act, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or such persons may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in the registration statement under
which such Registrable Securities were registered under the Securities Act
pursuant to Section 10, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse the Company and each such person for any reasonable legal or
other expenses incurred by them in connection with investigating or defending
any such loss, claim, damage, liability or action, provided, however, that the
Purchaser will be liable in any such case if and only to the extent that any
such loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission so made in
conformity with information furnished in writing to the Company by the Purchaser
specifically for use in any such document.

     (c) Promptly after receipt by an indemnified party hereunder of notice of
the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
such indemnified party other than under this Section 10.6(c) and shall only
relieve it from any liability which it may have to such indemnified party under
this Section 10.6(c) if and to the extent the indemnifying party is prejudiced
by such omission. In case any such action shall be brought against any
indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate in and, to the
extent it shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 10.6(c) for any legal expenses subsequently incurred by
such indemnified party in connection with the defense thereof; if the
indemnified party retains its own counsel, then the indemnified party shall pay
all fees, costs and expenses of such counsel, provided, however, that, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be reasonable defenses available to it which are different from
or additional to those available to the indemnifying party or if the interests
of the indemnified party reasonably may be deemed to conflict with the interests
of the indemnifying party, the indemnified parties shall have the right to
select one separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the reasonable expenses and fees
of such separate counsel and other expenses related to such participation to be
reimbursed by the indemnifying party as incurred.


                                       21


     (d) In order to provide for just and equitable contribution in the event of
joint liability under the Securities Act in any case in which either (i) the
Purchaser, or any controlling person of the Purchaser, makes a claim for
indemnification pursuant to this Section 10.6 but it is judicially determined
(by the entry of a final judgment or decree by a court of competent jurisdiction
and the expiration of time to appeal or the denial of the last right of appeal)
that such indemnification may not be enforced in such case notwithstanding the
fact that this Section 10.6 provides for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the part of the
Purchaser or controlling person of the Purchaser in circumstances for which
indemnification is provided under this Section 10.6; then, and in each such
case, the Company and the Purchaser will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution
from others) in such proportion so that the Purchaser is responsible only for
the portion represented by the percentage that the public offering price of its
securities offered by the registration statement bears to the public offering
price of all securities offered by such registration statement, provided,
however, that, in any such case, (A) the Purchaser will not be required to
contribute any amount in excess of the public offering price of all such
securities offered by it pursuant to such registration statement; and (B) no
person or entity guilty of fraudulent misrepresentation (within the meaning of
Section 10(f) of the Act) will be entitled to contribution from any person or
entity who was not guilty of such fraudulent misrepresentation.



                                       22


     11. OFFERING RESTRICTIONS. Except as previously disclosed in the SEC
Reports or in the Exchange Act Filings, or stock or stock options granted to
employees or directors of the Company; or equity or debt issued in connection
with an acquisition of a business or assets by the Company; or the issuance by
the Company of stock in connection with the establishment of a joint venture
partnership or licensing arrangement (these exceptions hereinafter referred to
as the "Excepted Issuances"), the Company will not issue any securities with a
variable/floating conversion feature which are or could be (by conversion or
registration) free-trading securities (i.e. common stock subject to a
registration statement) prior to the full repayment or conversion of the Note
(the "Exclusion Period"). This restriction shall not prohibit the Company from
issuing any equity, convertible debt or other securities prior to the expiration
of the Exclusion Period, provided that such equity, convertible debt or other
securities are restricted securities when issued and remain restricted until the
expiration of the Exclusion Period, which shall include, but not limited to, any
bank debt with warrants, fixed rate convertible debt transactions and/or
discounted equity transactions in each case with registration rights that
provide for registration of the Common Stock issuable therein after the
Exclusion Period.

     12. COLLATERAL.

     12.1 The Company will direct all present and future Account Debtors and
other persons obligated to make payments constituting Accounts to make such

North Fork Bank pursuant to the terms of the Lockbox Agreement dated April 29,
2003 or such other financial institution accepted by the Purchaser in writing as
may be selected by the Company (the "Lockbox Bank"). On or prior to the Closing
Date, the Company shall and shall cause the Lockbox Bank to enter into all such
documentation acceptable to the Purchaser pursuant to which, among other things,
the Lockbox Bank agrees to: (a) sweep the Lockbox on a daily basis and deposit
all checks received therein to an account designated by the Purchaser in writing
and (b) comply only with the instructions or other directions of the Purchaser
concerning the Lockbox. All of the Company's invoices, account statements and
other written or oral communications directing, instructing, demanding or
requesting payment of any Account of the Company or any other amount
constituting Accounts shall conspicuously direct that all payments be made to
the Lockbox or such other address as the Purchaser may direct in writing. If,
notwithstanding the instructions to Account Debtors, the Company receives any
payments, the Company shall immediately remit such payments to the Purchaser in
their original form with all necessary endorsements. Until so remitted, the
Company shall hold all such payments in trust for and as the property of the
Purchaser and shall not commingle such payments with any of its other funds or
property. The Company shall pay the Purchaser five percent (5%) of the amount of
any payment so received by the Company and not delivered in kind to the
Purchaser within five (5) Business Days following the Company's receipt thereof.

     12.2 The principal amount of the Note plus the principal amount of the note
issued by the Company to the Purchaser on July 26, 2002 in the initial principal
amount of $800,000 ("Current Investment Amount") shall not be greater than 90%
of the Eligible Accounts plus the Company's current cash (the "Formula"). In the
event that the Formula is not met, then the Purchaser shall apply proceeds of
Accounts to reduce the Current Investment Amount until the Formula is met.


                                       23


     12.3 At the Purchaser's election, (i) if an Event of Default set forth in
Sections 4.2 or 4.3 of the Note has occurred and is continuing for thirty (30)
days or (2) if an Event of Default specified in Sections 4.1, 4.4, 4.5, 4.6 4.7
or 4.9 of the Note has occurred and is continuing, the Purchaser may notify the
Company's Account Debtors of the Purchaser's security interest in the Accounts,
collect them directly and charge the collection costs and expenses thereof to
the Company's account.

     12.4 The Company will deliver or cause to be delivered to the Purchaser,
agings of the Company's Accounts on the 9th and the 24th respectively, of each
month during the term hereof..

     12.5 The Purchaser may verify the Company's Accounts utilizing an audit
control company or any other agent of the Purchaser. So long as no Default or
Event of Default shall have occurred and be continuing and/or the Purchaser does
not reasonably believe such verifications are necessary to preserve or protect
the Collateral or its rights and remedies under this Agreement and applicable
law, the Purchaser shall not verify the Company's Accounts more than four (4)
times during any calendar year and not more than two (2) times during any
consecutive six (6) month period.

     12.6 The Purchaser hereby agrees that if (i) the Formula set forth in
Section 12.2 hereof has been met and (ii) no Event of Default under the Note has
occurred and is continuing then Purchaser shall upon the written request of
Company transfer to such account as shall be designated by Company all available
amounts Purchaser holds on behalf of Company pursuant to that certain letter
agreement dated as of April 29, 2003 among the Company, Purchaser and North Fork
Bank.

     12.7 The Company hereby appoints the Purchaser, or any other person whom
the Purchaser may designate as the Company's attorney, with power to: (i)
endorse the Company's name on any checks, notes, acceptances, money orders,
drafts or other forms of payment or security that may come into the Purchaser's
possession; (ii) sign the Company's name on any invoice or bill of lading
relating to any Accounts, drafts against Account Debtors, schedules and
assignments of Accounts, notices of assignment, financing statements and other
public records, verifications of Account and notices to or from Account Debtors;
(iii) verify the validity, amount or any other matter relating to any Account by
mail, telephone, telegraph or otherwise with Account Debtors; (iv) do all things
necessary to carry out this Agreement, any Related Agreement and all related
documents; and (v) on or after the occurrence and continuation of an Event of
Default, notify the post office authorities to change the address for delivery
of the Company's mail to an address designated by the Purchaser, and to receive,
open and dispose of all mail addressed to the Company. The Company hereby
ratifies and approves all acts of the attorney. Neither the Purchaser, nor the
attorney will be liable for any acts or omissions or for any error of judgment
or mistake of fact or law. This power, being coupled with an interest, is
irrevocable so long as the Purchaser has a security interest and until all
obligations from the Company to the Purchaser have been fully satisfied.
Notwithstanding the immediately foregoing, the Purchaser shall not exercise any
powers granted to it pursuant to this Section 12.7 unless and until an Event of
Default under the Note shall have occurred and be continuing.

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

     FOR VALUE RECEIVED, DIGITAL FUSION, INC., a Delaware corporation
(hereinafter called the "Borrower"), hereby promises to pay to LAURUS MASTER
FUND, LTD., c/o Ironshore Corporate Services Ltd., P.O. Box 1234 G.T.,
Queensgate House, South Church Street, Grand Cayman, Cayman Islands, Fax:
345-949-9877 (the "Holder") or its registered assigns or successors in interest,
on order, without demand, the sum of Two Hundred Sixty Six Thousand and Six
Hundred Sixty Seven Dollars ($266,667), with any accrued and unpaid interest on
April 30, 2005 (the "Maturity Date"). Capitalized terms used herein without
definition shall have the meanings ascribed to such terms in the Purchase
Agreement (as defined in Section 3.1(a) below). This Note shall be convertible
into shares of the Borrower's common stock at the Fixed Conversion Price, as
defined below.

     The following terms shall apply to this Note:


                                    ARTICLE I

                           DEFAULT RELATED PROVISIONS

     1.1 Payment Grace Period. The Borrower shall have a ten (10) day grace
period to pay any monetary amounts due under this Note, after which grace period
a default interest rate of five percent (5%) per annum above the then applicable
interest rate hereunder shall apply to the monetary amounts due.



                                       3


     1.2 Conversion Privileges. The Conversion Privileges set forth in Article
III shall remain in full force and effect immediately from the date hereof and
until the Note is paid in full.

     1.3 Interest Rate. (a) Interest payable on this Note shall accrue at the
simple annual rate of six percent (6%) and be payable in arrears commencing on
May 30, 2003 and on the thirtieth day of each consecutive calendar month
thereafter, and on the Maturity Date, accelerated or otherwise, due and payable
as described below.

     (b) In addition to the interest rate set forth above in Section 1.3(a), an
additional fee on this Note shall accrue at the simple annual rate of four
percent (4%) and be payable in arrears commencing on May 30, 2003 and on the
thirtieth day of each consecutive calendar month thereafter, and on the Maturity
Date, accelerated or otherwise, when the principal and accrued but unpaid
interest shall be due and payable, or sooner as described below. Notwithstanding
the foregoing, for every dollar in principal amount of the Note that Holder
converts into Common Stock, the Holder will issue a credit to the Borrower (each
occurrence a "Rebate Credit") equal to the amount of time in years and fractions
thereof from the Closing Date (as defined in the Securities Purchase Agreement)
to the Conversion Date (as defined in section 3.1 (a)) times four percent (4%).
On the next Repayment Date (as defined in section 2.1), the Rebate Credit will
be paid by the Holder to the Borrower by a reduction in the Monthly Amount due
equal to the unpaid Rebate Credit.



ARTICLE II

                                  AMORTIZATION

     2.1 Monthly Payments. The Borrower shall repay one twenty-second (1/22nd)
of the original principal amount of this Note (to the extent such amount has not
been converted pursuant to Article III below), together with interest accrued to
date on such portion of the original principal amount plus any and all default
payments owing under the Purchase Agreement but not previously paid
(collectively the "Monthly Amount") on July 30, 2002 and on the thirtieth day of
each consecutive calendar month thereafter (each, a "Repayment Date"). On each
such Repayment Date, the Borrower shall pay to the Holder an amount equal to the
Monthly Amount in satisfaction of such obligation.



                                       4


ARTICLE III


CONVERSION RIGHTS



     3.1. Conversion into the Borrower's Common Stock.
          --------------------------------------------

     (a) For so long as the average closing price of the Common Stock for the 10
trading days prior to conversion is greater than 125% of the Fixed Conversion
Price (as defined below), the Holder shall have the right, but not the
obligation to convert the principal portion of this Note and/or interest due and
payable into fully paid and nonassessable shares of common stock of the Borrower
as such stock exists on the date of issuance of this Note, or any shares of
capital stock of the Borrower into which such stock shall hereafter be changed
or reclassified (the "Common Stock") at the fixed conversion price of $.35
subject to adjustment as provided in Section 3.1(b) hereof (the "Fixed
Conversion Price").

     The Borrower shall deliver a Notice of Conversion (as set forth on Exhibit
A attached hereto) as described in Section 9 of the Securities Purchase
Agreement entered into between the Borrower and the Holder relating to this Note
(the "Purchase Agreement") of the Holder's written request for conversion (the
date of giving such notice of conversion being a "Conversion Date"). The number
of shares of Common Stock to be issued upon each conversion of this Note shall
be determined by dividing that portion of the principal of the Note to be
converted and interest, if any, by the Fixed Conversion Price as of the
Conversion Date. In the event of any conversions of outstanding principal amount
under this Note in part pursuant to this Article III, such conversions shall be
deemed to constitute conversions of outstanding principal amount applying to
Monthly Amounts for the Repayment Dates in chronological order. By way of
example, if the original principal amount of this Note is $266,667 and the
Holder converted $24,242 of such original principal amount prior to the first
Repayment Date, then (1) the principal amount of the Monthly Amount due on the
first Repayment Date would equal $0, (2) the principal amount of the Monthly
Amount due on the second Repayment Date would equal $0 and (3) the principal
amount of the Monthly Amount due on each of the remaining Repayment Dates would
be $12,121.


     (b) The Fixed Conversion Price and number and kind of shares or other
securities to be issued upon conversion determined pursuant to Section 3.1(a),
shall be subject to adjustment from time to time upon the happening of certain
events while this conversion right remains outstanding, as follows:



                                       5





     A. Stock Splits, Combinations and Dividends. If the shares of Common Stock
are subdivided or combined into a greater or smaller number of shares of Common
Stock, or if a dividend is paid on the Common Stock in shares of Common Stock,
the Fixed Conversion Price or the Conversion Price, as the case may be, shall be
proportionately reduced in case of subdivision of shares or stock dividend or
proportionately increased in the case of combination of shares, in each such
case by the ratio which the total number of shares of Common Stock outstanding
immediately after such event bears to the total number of shares of Common Stock
outstanding immediately prior to such event.

     (c) During the period the conversion right exists, the Borrower will
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of Common Stock upon the full conversion of
this Note. The Borrower represents that upon issuance, such shares will be duly
and validly issued, fully paid and non-assessable. The Borrower agrees that its
issuance of this Note shall constitute full authority to its officers, agents,
and transfer agents who are charged with the duty of executing and issuing stock
certificates to execute and issue the necessary certificates for shares of
Common Stock upon the conversion of this Note.

     3.2 Method of Conversion. This Note may be converted by the Holder in whole
or in part as described in Section 3.1(a) hereof and the Purchase Agreement.
Upon partial conversion of this Note, a new Note containing the same date and
provisions of this Note shall, at the request of the Holder, be issued by the
Borrower to the Holder for the principal balance of this Note and interest which
shall not have been converted or paid. The Borrower will pay no costs, fees or
any other consideration to the Holder for the production and issuance of a new
Note.




ARTICLE IV

                                EVENT OF DEFAULT

     If an Event of Default occurs and is continuing, the Holder may make all
sums of principal, interest and other fees then remaining unpaid hereon and all
other amounts payable hereunder due and payable within 30 days of written notice
from Holder to Borrower (each occurrence being a "Default Notice Period") of an
Event of Default (as defined below). In the event of such an acceleration, the
amount due and owing to the Holder shall be 115% of the outstanding principal
amount of the Note (plus accrued and unpaid interest and fees, if any) (the
"Acceleration Rate"). If during the Default Notice Period, Borrower cures the
Event of Default (other than a payment default described in section 4.1 below),
the Event of Default will no longer exist and any rights Holder had pertaining
to the Event of Default will no longer exist.


                                       6


     If after the Default Notice Period the Borrower has not repaid in full
amount then due hereunder, then, and only then, the conversion price hereunder
shall be reduced and shall be equal to the lower of (i) the Fixed Conversion
Price; or (ii) seventy percent (70%) of the average of the three lowest closing
prices for the Common Stock on the Principal Market, for the thirty (30) trading
days prior to but not including the Conversion Date. The "Principal Market"
shall include the NASD OTC Bulletin Board, NASDAQ SmallCap Market, NASDAQ
National Market System, American Stock Exchange, or New York Stock Exchange
(whichever of the foregoing is at the time the principal trading exchange or
market for the Common Stock, or any securities exchange or other securities
market on which the Common Stock is then being listed or traded.

     The occurrence of any of the following events is an Event of Default
("Event of Default"):

     4.1 Failure to Pay Principal, Interest or other Fees. The Borrower fails to
pay any installment of principal, interest or other fees hereon or on any other
promissory note issued pursuant to the Purchase Agreement and this Note, when
due and such failure continues for a period of ten (10) days after the due date.

     4.2 Breach of Covenant. The Borrower breaches any material covenant or
other term or condition of this Note or the Purchase Agreement in any material
respect and such breach, if subject to cure, continues for a period of ten (10)
days after written notice to the Borrower from the Holder.

     4.3 Breach of Representations and Warranties. Any material representation
or warranty of the Borrower made herein, in the Purchase Agreement, or in any
agreement, statement or certificate given in writing pursuant hereto or in
connection therewith shall be false or misleading and shall not be cured for a
period of twenty (20) days after written notice thereof is received by the
Borrower from the Holder.

     4.4 Receiver or Trustee. The Borrower shall make an assignment for the
benefit of creditors, or apply for or consent to the appointment of a receiver
or trustee for it or for a substantial part of its property or business; or such
a receiver or trustee shall otherwise be appointed.

     4.5 Judgments. Any money judgment, writ or similar final process shall be
entered or filed against the Borrower or any of its property or other assets for
more than $250,000, and shall remain unvacated, unbonded or unstayed for a
period of ninety (90) days.

     4.6 Bankruptcy. Bankruptcy, insolvency, reorganization or liquidation
proceedings or other proceedings or relief under any bankruptcy law or any law
for the relief of debtors shall be instituted by or against the Borrower.

     4.7 Stop Trade. An SEC stop trade order or Principal Market trading
suspension of the Common Stock for 5 consecutive days or 5 days during a period
of 10 consecutive days, excluding in all cases a suspension of all trading on a
Principal Market, provided that the Borrower shall not have been able to cure
such trading suspension within 30 days of the notice thereof or list the Common
Stock on another Principal Market within 60 days of such notice.



                                       7





     4.8 Failure to Deliver Common Stock or Replacement Note. The Borrower's
failure to timely deliver Common Stock to the Holder pursuant to and in the form
required by this Note and Section 9 of the Purchase Agreement, or if required a
replacement Note.

     4.9 Default under Related Agreement. An Event of Default occurs under and
as defined in the Note from the Borrower to the Holder dated on or about July
26, 2002, as such note may be amended, modified and supplemented from time to
time.



                                    ARTICLE V

                                  MISCELLANEOUS

     5.1 Failure or Indulgence Not Waiver. No failure or delay on the part of
the Holder hereof in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such power, right or privilege preclude other or further exercise thereof or
of any other right, power or privilege. All rights and remedies existing
hereunder are cumulative to, and not exclusive of, any rights or remedies
otherwise available.

     5.2 Notices. Any notice herein required or permitted to be given shall be

                                       8

throughout this instrument, shall mean this instrument as originally executed,
or if later amended or supplemented, then as so amended or supplemented.

Note.

or require the payment of a rate of interest or other charges in excess of the
maximum permitted by applicable law. In the event that the rate of interest
required to be paid or other charges hereunder exceed the maximum permitted by
such law, any payments in excess of such maximum shall be credited against
amounts owed by the Borrower to the Holder and thus refunded to the Borrower.

     5.7 Security Interest. The holder of this Note has been granted a security
interest in certain assets of the Borrower more fully described in a Security
Agreement.

                  5.8 Construction. Each party acknowledges that its legal
counsel participated in the preparation of this Note and, therefore, stipulates
that the rule of construction that ambiguities are to be resolved against the
drafting party shall not be applied in the interpretation of this Note to favor
any party against the other.

     1. Exercise of Warrant.

     1.1. Number of Shares Issuable upon Exercise. From and after the date
hereof through and including the Expiration Date, the holder hereof shall be

accordance with subsection 1.3, shares of Common Stock of the Company, subject
to adjustment pursuant to Section 4.

     1.2. Full Exercise. This Warrant may be exercised in full by the holder
hereof by delivery of an original or fax copy of the form of subscription
attached as Exhibit A hereto (the "Subscription Form") duly executed by such
Holder, to the Company at its principal office or at the office of its warrant
agent (as provided hereinafter), accompanied by payment, in cash, wire transfer,
or by certified or official bank check payable to the order of the Company, in
the amount obtained by multiplying the number of shares of Common Stock for
which this Warrant is then exercisable by the Purchase Price (as hereinafter
defined) then in effect.

     1.3. Partial Exercise. This Warrant may be exercised in part (but not for a
fractional share) by surrender of this Warrant in the manner and at the place
provided in subsection 1.2 except that the amount payable by the holder on such
partial exercise shall be the amount obtained by multiplying (a) the number of
shares of Common Stock designated by the holder in the Subscription Form by (b)
the Purchase Price then in effect. On any such partial exercise, the Company, at
its expense, will forthwith issue and deliver to or upon the order of the holder
hereof a new Warrant of like tenor, in the name of the holder hereof or as such
holder (upon payment by such holder of any applicable transfer taxes) may
request, the number of shares of Common Stock for which such Warrant may still
be exercised.

     1.4. Fair Market Value. Fair Market Value of a share of Common Stock as of
a particular date (the "Determination Date") shall mean:

     (a) If the Company's Common Stock is traded on an exchange or is quoted on
the National Association of Securities Dealers, Inc. Automated Quotation
("NASDAQ") National Market System or the NASDAQ SmallCap Market, then the
average closing or last sale price, respectively, reported for the ten business
days immediately preceding the Determination Date.

     (b) If the Company's Common Stock is not traded on an exchange or on the
NASDAQ National Market System or the NASDAQ SmallCap Market but is traded on the
NASD OTC Bulletin Board, then the mean of the average of the closing bid and
asked prices reported for the ten business days immediately preceding the
Determination Date.

     (c) Except as provided in clause (d) below, if the Company's Common Stock
is not publicly traded, then as the Holder and the Company agree or in the
absence of agreement by arbitration in accordance with the rules then standing
of the American Arbitration Association, before a single arbitrator to be chosen
from a panel of persons qualified by education and training to pass on the
matter to be decided.

     (d) If the Determination Date is the date of a liquidation, dissolution or
winding up, or any event deemed to be a liquidation, dissolution or winding up
pursuant to the Company's charter, then all amounts to be payable per share to
holders of the Common Stock pursuant to the charter in the event of such
liquidation, dissolution or winding up, plus all other amounts to be payable per
share in respect of the Common Stock in liquidation under the charter, assuming
for the purposes of this clause (d) that all of the shares of Common Stock then
issuable upon exercise of the Warrant are outstanding at the Determination Date.


                                       13


     1.5. Company Acknowledgment. The Company will, at the time of the exercise
of the Warrant, upon the request of the holder hereof acknowledge in writing its
continuing obligation to afford to such holder any rights to which such holder
shall continue to be entitled after such exercise in accordance with the
provisions of this Warrant. If the holder shall fail to make any such request,
such failure shall not affect the continuing obligation of the Company to afford
to such holder any such rights.

     1.6. Trustee for Warrant Holders. In the event that a bank or trust company
shall have been appointed as trustee for the holders of the Warrant pursuant to
Subsection 3.2, such bank or trust company shall have all the powers and duties
of a warrant agent (as hereinafter described) and shall accept, in its own name
for the account of the Company or such successor person as may be entitled
thereto, all amounts otherwise payable to the Company or such successor, as the
case may be, on exercise of this Warrant pursuant to this Section 1.

     2.1 Delivery of Stock Certificates, etc. on Exercise. The Company agrees
that the shares of Common Stock purchased upon exercise of this Warrant shall be
deemed to be issued to the holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within 7 days thereafter, the Company at its expense (including the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and delivered to the holder hereof, or as such holder (upon payment by such
holder of any applicable transfer taxes) may direct in compliance with
applicable Securities Laws, a certificate or certificates for the number of duly
and validly issued, fully paid and nonassessable shares of Common Stock (or
Other Securities) to which such holder shall be entitled on such exercise, plus,
in lieu of any fractional share to which such holder would otherwise be
entitled, cash equal to such fraction multiplied by the then Fair Market Value
of one full share, together with any other stock or other securities and
property (including cash, where applicable) to which such holder is entitled
upon such exercise pursuant to Section 1 or otherwise.

     2.2. Payment of Purchase Price.

     (a) Payment may be made either in (i) cash or by certified or official bank
check payable to the order of the Company equal to the applicable aggregate
Purchase Price, (ii) by delivery of the Warrant, Common Stock and/or Common
Stock receivable upon exercise of the Warrant in accordance with Section (b)
below, or (iii) by a combination of any of the foregoing methods, for the number
of Common Shares specified in such form (as such exercise number shall be
adjusted to reflect any adjustment in the total number of shares of Common Stock
issuable to the holder per the terms of this Warrant) and the holder shall
thereupon be entitled to receive the number of duly authorized, validly issued,
fully-paid and non-assessable shares of Common Stock (or Other Securities)
determined as provided herein.

     (b) Notwithstanding any provisions herein to the contrary, if the Fair
Market Value of one share of Common Stock is greater than the Purchase Price (at
the date of calculation as set forth below), in lieu of exercising this Warrant
for cash, the holder may elect to receive shares equal to the value (as
determined below) of this Warrant (or the portion thereof being cancelled) by
surrender of this Warrant at the principal office of the Company together with
the properly endorsed Subscription Form in which event the Company shall issue
to the holder a number of shares of Common Stock computed using the following
formula:

                                       14


                           X=Y (A-B)
                                ---

                            A
                     --------

                  Where    X=       the number of shares of Common Stock to be
                                    issued to the holder

                           Y=       the number of shares of Common Stock
                                    purchasable under the Warrant or, if only a
                                    portion of the Warrant is being exercised,
                                    the portion of the Warrant being exercised
                                    (at the date of such calculation)

                           A=       the Fair Market Value of one share of the
                                    Company's Common Stock (at the date of such
                                    calculation)

                           B=       Purchase Price (as adjusted to the date of
                                    such calculation)

     3. Adjustment for Reorganization, Consolidation, Merger, etc.

     3.1. Reorganization, Consolidation, Merger, etc. In case at any time or
from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the holder of this
Warrant, upon the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.



     3.2. Continuation of Terms. Upon any reorganization, consolidation, merger
or transfer (and any dissolution following any transfer) referred to in this
Section 3, this Warrant shall continue in full force and effect and the terms
hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant as provided in Section 4.

     4. Extraordinary Events Regarding Common Stock. In the event that the
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be increased or decreased to a number determined by multiplying
the number of shares of Common Stock that would otherwise (but for the
provisions of this Section 4) be issuable on such exercise by a fraction of
which (a) the numerator is the Purchase Price that would otherwise (but for the
provisions of this Section 4) be in effect, and (b) the denominator is the
Purchase Price in effect on the date of such exercise.


                                       15


     5. Certificate as to Adjustments. In each case of any adjustment or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrant, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price
and the number of shares of Common Stock to be received upon exercise of this
Warrant, in effect immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant. The Company will forthwith
mail a copy of each such certificate to the holder of the Warrant and any
Warrant agent of the Company (appointed pursuant to Section 11 hereof).

     6. Reservation of Stock, etc. Issuable on Exercise of Warrant; Financial
Statements. The Company will at all times reserve and keep available, solely for
issuance and delivery on the exercise of the Warrant, all shares of Common Stock
(or Other Securities) from time to time issuable on the exercise of the Warrant.
This Warrant entitles the holder hereof to receive copies of all financial and
other information distributed or required to be distributed to the holders of
the Company's Common Stock.

     7. Assignment; Exchange of Warrant. Subject to compliance with applicable
Securities laws, this Warrant, and the rights evidenced hereby, may be
transferred by any registered holder hereof (a "Transferor") with respect to any
or all of the Shares. On the surrender for exchange of this Warrant, with the
Transferor's endorsement in the form of Exhibit B attached hereto (the
"Transferor Endorsement Form") and together with evidence reasonably
satisfactory to the Company demonstrating compliance with applicable Securities
Laws, which shall include, without limitation, a legal opinion from the
Transferor's counsel that such transfer is exempt from the registration
requirements of federal securities laws, the Company at its expense but with
payment by the Transferor of any applicable transfer taxes) will issue and
deliver to or on the order of the Transferor thereof a new Warrant of like
tenor, in the name of the Transferor and/or the transferee(s) specified in such
Transferor Endorsement Form (each a "Transferee"), calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant so surrendered by the Transferor.

     8. Replacement of Warrant. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of any such loss, theft or destruction of this Warrant, on
delivery of an indemnity agreement or security reasonably satisfactory in form
and amount to the Company or, in the case of any such mutilation, on surrender
and cancellation of this Warrant, the Company at its expense will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

     9. Registration Rights. The Holder of this Warrant has been granted certain
registration rights by the Company. These registration rights are set forth in a
Securities Purchase Agreement entered into by the Company and the Holder.


                                       16


     10. Maximum Exercise. The Holder shall not be entitled to exercise this
Warrant on an exercise date, in connection with that number of shares of Common
Stock which would be in excess of the sum of (i) the number of shares of Common
Stock beneficially owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date, which would result in beneficial ownership by the Holder and
its affiliates of more than 4.9% of the outstanding shares of Common Stock of
the Company on such date. For the purposes of the proviso to the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation
13d-3 thereunder. Subject to the foregoing, the Holder shall not be limited to
aggregate exercises which would result in the issuance of more than 4.9%. The
restriction described in this paragraph is automatically null and void upon an
Event of Default under the Note..

     11. Warrant Agent. The Company may, by written notice to the each holder of
the Warrant, appoint an agent for the purpose of issuing Common Stock (or Other
Securities) on the exercise of this Warrant pursuant to Section 1, exchanging
this Warrant pursuant to Section 7, and replacing this Warrant pursuant to
Section 8, or any of the foregoing, and thereafter any such issuance, exchange
or replacement, as the case may be, shall be made at such office by such agent.

     12. Transfer on the Company's Books. Until this Warrant is transferred on
the books of the Company, the Company may treat the registered holder hereof as
the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

     13. Notices, etc. All notices and other communications from the Company to
the holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company in writing by such holder or, until any such holder furnishes to the
Company an address, then to, and at the address of, the last holder of this
Warrant who has so furnished an address to the Company.

     14. Voluntary Adjustment by the Company. The Company may at any time during
the term of this Warrant reduce the then current Exercise Price to any amount
and for any period of time deemed appropriate by the Board of Directors of the
Company.

     15. Miscellaneous. This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought. This Warrant shall be governed by and construed in accordance with the
laws of State of New York without regard to principles of conflicts of laws. Any
action brought concerning the transactions contemplated by this Warrant shall be
brought only in the state courts of New York or in the federal courts located in
the state of New York. The individuals executing this Warrant on behalf of the
Company agree to submit to the jurisdiction of such courts and waive trial by
jury. The prevailing party shall be entitled to recover from the other party its
reasonable attorney's fees and costs. In the event that any provision of this
Warrant is invalid or unenforceable under any applicable statute or rule of law,
then such provision shall be deemed inoperative to the extent that it may
conflict therewith and shall be deemed modified to conform with such statute or
rule of law. Any such provision which may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provision
of this Warrant. The headings in this Warrant are for purposes of reference
only, and shall not limit or otherwise affect any of the terms hereof. The
invalidity or unenforceability of any provision hereof shall in no way affect
the validity or enforceability of any other provision. The Company acknowledges


                                       17



that legal counsel participated in the preparation of this Warrant and,
therefore, stipulates that the rule of construction that ambiguities are to be
resolved against the drafting party shall not be applied in the interpretation
of this Warrant to favor any party against the other party.
