        THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT
        OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, OR
        HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
        RELATED THERETO OR AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO THE
        COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT
        OF 1933, AS AMENDED.

                                     WARRANT
                                       of
                                YELLOWBRIX, INC.

November 29, 2000

        THIS CERTIFIES that, for value received, ABN AMRO Capital (USA) Inc.
(the "Warrantholder"), is entitled, upon the terms and subject to the conditions
set forth herein, to purchase from YellowBrix, Inc., a Delaware corporation (the
"Company"), either the number of shares of common stock, par value $.001 per
share (the "Common Stock"), of the Company (the "Shares") set forth in Schedule
A attached hereto, as subject to adjustments as described herein, or Series A
Preferred Stock, par value $.001 per share (the "Series A Preferred Stock") at
the purchase price per share described below.

        This Warrant is being issued to the Warrantholder in conjunction with
the issuance of $700,000 of Secured Promissory Notes pursuant to the Note and
Warrant Purchase Agreement, dated as of November 29, 2000 (the "Purchase
Agreement"), and is subject to the following terms and conditions:

        1.      Exercise of Warrant.

                (a)     Exercise and Payment. This Warrant may be exercised in
whole or in part, at any time, or from time to time, after the date hereof and
on or before the seventh anniversary of the date hereof by the surrender of this
Warrant and the Notice of Exercise annexed hereto (duly completed and executed
on behalf of the Warrantholder) to the Company and by (i) the payment of the
Exercise Price (as defined below) for the Shares to be purchased by the
Warrantholder to the Company by cash, check, cancellation of indebtedness, or
transfer of shares of Common Stock, or any combination thereof; (ii) by Cashless
Exercise as provided in Section 13 hereof; or (iii) by Same Day Exercise and
Sale as provided in Section 14 hereof. The Company will prepare and deliver a
certificate for the Shares purchased and, if this Warrant is exercised in part,
a new Warrant for the unexercised portion of this Warrant. The Company agrees
that, upon exercise of this Warrant in accordance with the terms hereof, the
Shares so purchased will be deemed to be issued to the Warrantholder as the
record owner of such Shares as of the close of business on the date on which
this Warrant was exercised.

<PAGE>   2


                (b)     Delivery of Shares. Certificates for Shares purchased
under this Warrant and, on partial exercise of this Warrant, a new Warrant for
the unexercised portion of this Warrant will be delivered to the Warrantholder
or to such person or persons as the Warrantholder may direct as promptly as
practicable after the date on which this Warrant was exercised. The Company
covenants that all Shares that may be issued upon the exercise of rights
represented by this Warrant will, upon exercise of the rights represented by
this Warrant, payment of the Exercise Price and issuance by the Company, be duly
authorized, validly issued, fully paid and nonassessable.

        2.      Reservation of Shares; No Impairment or Amendment. The Company
will at all times reserve and keep available, solely for issuance, sale and
delivery upon the exercise of this Warrant, a number of shares of Common Stock
and Series A Preferred Stock (as described below) equal to the number of shares
of Common Stock or Series A Preferred Stock issuable upon the exercise of this
Warrant. The Company will not by any amendment of its Certificate of
Incorporation or By-laws or through any other means, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant. The Company will
take all such reasonable action as may be necessary to assure that such shares
of Common Stock and Series A Preferred Stock may be issued as provided herein
without violation of any applicable law or regulation, or of any requirements of
any domestic securities exchange or automated quotation system upon which the
shares of Common Stock may be listed.

        3.      Expiration. This Warrant, if not exercised by Warrantholder
prior thereto, will expire on the seventh anniversary of its respective grant
date.

        4.      Exercise Price. Subject to adjustment as hereinafter described,
the price per share payable to the Company on the exercise of the purchase right
evidenced by this Warrant shall be $3.72 per Share (the "Exercise Price") and
the Warrant shall be exercisable for 188,172 shares of Common Stock.

                (a)     Adjustment to Exercise Price Based On Private Equity
Qualified Financing. Unless otherwise mutually agreed to in writing, in the
event the Company enters into a transaction resulting in gross proceeds to the
Company in excess of an amount equal to $10,000,000 minus the Over-Advance (as
defined below) from the sale of preferred stock (the "Private Equity Qualified
Financing"), the Exercise Price shall equal eighty-five percent (85%) of the
purchase price per share in such Private Equity Qualified Financing. The
"Over-Advance" shall mean the amount of any and all Notes and Advances (both as
defined in the Note and Warrant Purchase Agreement of even date herewith) in
excess of $2,000,000.

                (b)     Adjustment to Exercise Price Based on IPO Qualified
Financing. Unless otherwise mutually agreed to in writing, in the event the
Company completes an initial public offering of its securities in a gross amount
of at least $30,000,000 on any national market or exchange (the "IPO Qualified
Financing"), the Exercise Price shall equal $3.72.


                                      -2-
<PAGE>   3


                (c)     Adjustment to Exercise Price After May 31, 2001. Unless
otherwise agreed to in writing, if a Qualified Financing or Exchange Transaction
(as described below) does not occur on or before May 31, 2001, the Warrant shall
be convertible into shares of the Company's Series A Preferred Stock, par value
$.001 per share (the "Series A Preferred Stock"). The number of Series A
Preferred Stock issuable upon exercise of the Warrant shall equal the number of
Shares multiplied by $3.72 and divided by 10; provided, however, that a
conversion price of $1.78 per share shall apply to the conversion of such Series
A Preferred Stock into Common Stock as described in Section 3.4 of the
Certificate of Designation of such Series A Preferred Stock.

                (d)     Adjustment to Number of Shares. In the event the
Exercise Price is adjusted pursuant to this Section 4, the number of Shares for
which this Warrant is exercisable shall be equal to 188,172 multiplied by a
fraction, the numerator of which is shall be the exercise price prior to
adjustment and the denominator of which shall be the exercise price as adjusted
by this Section 4.

                (e)     Antidilution.

                (1)     If any capital reorganization or reclassification of the
capital stock of the Company, or an Exchange Transaction (as defined below), or
the sale of all or substantially all of its assets to another corporation (the
"Sale") shall be effected in such a way that holders of Common Stock shall be
entitled to receive stock, securities, cash or other property with respect to or
in exchange for Common Stock, then, as a condition of such reorganization,
reclassification, Exchange Transaction or sale, lawful and adequate provision
shall be made whereby the holder of this Warrant shall have the right to acquire
and receive upon exercise of this Warrant such shares of stock, securities, cash
or other property issuable or payable (as part of the reorganization,
reclassification, Exchange Transaction or Sale) with respect to or in exchange
for such number of outstanding shares of the Company's Common Stock as would
have been received upon exercise of this Warrant at the Exercise Price then in
effect immediately preceding such reorganization, reclassification, Exchange
Transaction or Sale.

                (2)     The Company will not effect any such Exchange
Transaction or Sale, unless prior to the consummation thereof the successor
entity (if other than the Company) resulting from such Exchange Transaction or
the entity purchasing such assets shall assume by written instrument mailed or
delivered to the holder of this Warrant at the last address of such holder
appearing on the books of the Company, the obligation to deliver to such holder
such shares of stock, securities or assets as, in accordance with the foregoing
provisions, such Warrantholder may be entitled to purchase.

                (3)     If a purchase, tender or exchange offer is made to and
accepted by the holders of more than 50% of the outstanding shares of Common
Stock of the Company, the Company shall not effect any Exchange Transaction or
sale with the person having made such offer or with any Affiliate of such
person, unless prior to the consummation of such Exchange Transaction or sale
the holder of this Warrant shall have been given a reasonable opportunity to
then elect to receive upon the exercise of this



                                      -3-
<PAGE>   4


Warrant either the stock, securities or assets then issuable with respect to the
Common Stock of the Company or the stock, securities or assets, or the
equivalent, issued to previous holders of the Common Stock in accordance with
such offer.

                (4)     Notwithstanding the foregoing, in the event of an
Exchange Transaction with is a merger or acquisition of the Company, the
acquirer ("Acquirer") may repurchase the Warrant by payment in U.S. dollars,
simultaneously with such merger or acquisition, to the Warrantholder in the
following amount: the number of shares of Common Stock (or Common Stock
resulting from the conversion of Series A Preferred Stock in the event Section
4(b) hereof has been applied) purchasable pursuant to the Warrant multiplied by
the difference between the price per share offered by the Acquirer for such
Common Stock or Series A Preferred Stock and the Exercise Price.

                (5)     For purposes hereof, the term "Affiliate" with respect
to any given person shall mean any person controlling, controlled by or under
common control with the given person.

                (6)     For purposes hereof, the term "Exchange Transaction"
means a merger (other than a merger of the Company in which the holders of
Common Stock immediately prior to the merger have the same proportionate
ownership of Common Stock in the surviving entity immediately after the merger),
consolidation, disposition of property or stock, separation, reorganization
(other than a mere reincorporation or the creation of a holding company),
liquidation of the Company or any other similar transaction or event so
designated by the Board, in its reasonable good faith judgment, as a result of
which the stockholders of the Company receive cash, stock or other property in
exchange for or in connection with their shares of Common Stock.

                (7)     In case the Company shall at any time subdivide its
outstanding shares of Common Stock into a greater number of shares, the Exercise
Price in effect immediately prior to such subdivision shall be proportionately
reduced and the number of shares purchasable under this Warrant shall be
proportionately increased. Conversely, in case the Common Stock shall be
combined into a smaller number of shares, the Exercise Price in effect
immediately prior to such combination shall be proportionately increased and the
number of shares purchasable hereunder shall be proportionately reduced.

                (8)     If the Company shall declare a dividend on its Common
Stock payable in stock or other securities of the Company or of any other
entity, or in property or otherwise than in cash, to holders of record of the
Common Stock as of a date prior to the date of exercise of this Warrant, the
Warrantholder shall, without additional cost, be entitled to receive upon the
exercise hereof, in addition to the Common Stock to which the Warrantholder is
otherwise entitled upon such exercise, the number of shares of stock or other
securities or property which the Warrantholder would have been entitled to
receive if the Warrantholder had been a holder of Common Stock on such record
date.

                (9)     No fractional shares of Common Stock are to be issued
upon the exercise of this Warrant, but the Company shall pay a cash adjustment
in respect of any



                                      -4-
<PAGE>   5


fraction of a share which would otherwise be issuable in an amount equal to the
same fraction of the fair market value per share of Common Stock on the date of
exercise, as reasonably determined by the Board of Directors; however, such
determination shall not take into any account any restraints or limitations on
the transferability of the Common Stock.

        4.      Notice of Adjustment; Notices. Whenever the Exercise Price or
number of shares purchasable hereunder will be adjusted, the Company at its
expense will promptly issue a certificate signed by an executive officer of the
Company setting forth, in reasonable detail, the event requiring the adjustment,
the amount of the adjustment, the method by which such adjustment was calculated
and the Exercise Price and number of shares purchasable hereunder after giving
effect to such adjustment, and will cause a copy of such certificate to be sent
to the Warrantholder.

        5.      Warrantholder Representation. The Warrantholder, by acceptance
hereof, acknowledges that this Warrant and Shares to be issued upon exercise
hereof, are being acquired solely for the Warrantholder's own account or for the
account of non-U.S. persons.

        6.      Transfer of Warrant. The Warrantholder will not offer, sell or
otherwise dispose of this Warrant or the Shares to be issued upon exercise
hereof except after providing the Company with a written opinion of legal
counsel, with such opinion shall be reasonably acceptable to the Company, that
such sale or disposition has been registered under, or qualifies for an
exemption from registration under, Securities Act of 1933, as amended (the
"Act") or other applicable federal or state securities laws and, if such
transfer occurs within six months of the date of this Warrant, that such sale or
disposition does not violate any integration provisions of the Act with regard
to the Company's IPO Qualified Financing, if any. In order to transfer this
Warrant, the Warrantholder must deliver to the Company this Warrant together
with the Assignment Form annexed hereto properly endorsed. Upon receipt thereof,
the Company will affect such transfer as promptly as practicable.
Notwithstanding anything to the contrary in this Warrant, the Warrantholder
agrees for a period of six months following receipt of this Warrant that it will
not transfer any portion of this Warrant to any person that is not a "qualified
institutional buyer" as that term is defined under Rule 144A of the Securities
Act (as hereinafter defined) or, if the Warrantholder is not a qualified
institutional buyer, to any person that is not an accredited investor as that
term is defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the
Securities Act with at least $35,000,000 of investment assets.

        7.      No Voting Rights, Etc. Prior to the proper exercise of this
Warrant, the Warrantholder, as such, is not entitled to vote or receive
dividends or be deemed to be a shareholder of the Company for any purposes, nor
may anything contained in this Warrant be construed to confer such rights upon
Warrantholder.

        8.      Registry of Warrant. The Company will maintain a registry
showing the name and address of the Warrantholder and the Company will be
entitled to rely in all



                                      -5-
<PAGE>   6


respects, prior to written notice to the contrary, upon such registry. The
Warrantholder is responsible for notifying the Company of any change of its
address.

        9.      Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt
of evidence satisfactory to it the Company of the loss, theft, destruction or
mutilation of a Warrant or any warrant issued in exchange therefor and, if
requested in the case of any such loss, theft or destruction, upon delivery of
an indemnity bond or other agreement or security reasonably satisfactory to the
Company, or, in the case of any such mutilation, upon surrender and cancellation
of such warrant, the Company will issue a new warrant, of like tenor and amount
and dated the date of the original Warrant, in lieu of such lost, stolen,
destroyed or mutilated Warrant; provided, however, if any Warrant of which a
Warrantholder, its nominee, or any of its partners or affiliates is the
registered holder is lost, stolen or destroyed, the affidavit of the registered
holder setting forth the circumstances with respect to such loss, theft or
destruction shall be accepted as satisfactory evidence thereof, and no
indemnification bond or other security shall be required as a condition to the
execution and delivery by the Company of a new warrant in replacement of such
lost, stolen or destroyed warrant other than the registered holder's written
agreement to indemnify the Company.

        10.     Office for Exercise or Exchange. This Warrant may be surrendered
for exchange, transfer or exercise, in accordance with its terms, at the
principal office of the Company, or at such other office or such other office or
agency of the Company as it may designate in writing to the Warrantholder at its
address appearing on the Company's registry or other books.

        11.     Charges, Taxes and Expenses. Issuance of certificates to the
Warrantholder for Shares upon the exercise of this Warrant will be made without
charge to the Warrantholder for any issue or transfer tax or other incidental
expense in respect of the issuance of such certificates, all of which taxes and
expenses will be paid by the Company. However, if the certificates are to be
issued in a name or names other than the name of the Warrantholder, the Company
may require, as a condition to such issuance, the payment of a sum sufficient to
reimburse it for any transfer tax incidental thereto.

        13.     Cashless Exercise. In lieu of payment of the aggregate Exercise
Price, the Warrantholder may exercise this Warrant with respect to the Shares
that are then vested and exercisable, in whole or in part, by presentation and
surrender of this Warrant to the Company, together with a Cashless Exercise Form
attached hereto (or a reasonable facsimile thereof) duly executed (a "Cashless
Exercise"). Such presentation and surrender shall be deemed a waiver of the
Warrantholder's obligation to pay all or any portion of the aggregate Exercise
Price. In the event of a Cashless Exercise, the Warrantholder shall exchange
this Warrant for that number of shares of Common Stock determined by multiplying
the number of Shares being exercised by a fraction, the numerator of which shall
be the difference between the then current market price per share of the Common
Stock and the Exercise Price, and the denominator of which shall be the then
current market price per share of Common Stock. For purposes of any computation
under this Section 13, the then current market price per share of Common



                                      -6-
<PAGE>   7


Stock at any date shall be deemed to be the average for the five consecutive
business days immediately prior to the Cashless Exercise of the daily closing
prices of the Common Stock on the principal national securities exchange on
which the Common Stock is admitted to trading or listed, or if not listed or
admitted to trading on any such exchange, the closing prices as reported by the
Nasdaq National Market, or if not then listed on the Nasdaq National Market, the
average of the highest reported bid and lowest reported asked prices as reported
by the National Association of Securities Dealers, Inc. Automated Quotations
System ("NASDAQ") or if not then publicly traded, the fair market price of the
Common Stock as determined by the Board in its reasonable good faith judgment.

        14.     Same Day Exercise and Sale. In lieu of exercising this Warrant
as set forth herein, when permitted by law and applicable regulations (including
rules promulgated by the NASDAQ or the National Association of Securities
Dealers ("NASD")), the Warrantholder may pay the Exercise Price through a same
day sale commitment from the Warrantholder (and if applicable a broker-dealer
that is a member of the NASD ("NASD Dealer")) whereby the Warrantholder would
irrevocably elect to exercise the Warrant and to sell a portion of the shares so
purchased to pay for the Exercise Price and the Warrantholder (or if applicable,
the NASD Dealer) would commit upon sale (or, in the case of the NASD Dealer,
upon receipt) of such shares to forward the exercise price directly to Company.

        15.     Market Standoff. If requested by the Company and an underwriter
of Common Stock (or other securities of the Company), the Warrantholder shall
not sell or otherwise transfer or dispose of any shares of Common Stock or
Series A Preferred Stock (or other securities) held by the Warrantholder after
an exercise of this Warrant, other than distributions to limited partners,
affiliates or parent entities of the Warrantholder, during the one hundred
eighty (180) day period following the effective date of the initial registration
statement of the Company filed under the Act. The Company may impose
stop-transfer instructions with respect to the shares of Common Stock and Series
A Preferred Stock (or other securities of the Company) subject to the foregoing
restrictions until the end of such one hundred eighty (180) day period.

        16.     Miscellaneous.

                (a)     Governing Law. This Warrant constitutes a contract under
and will be construed in accordance with and governed by the internal laws of
the State of Delaware.

                (b)     Successors and Assigns. This Warrant is binding upon any
successors or assigns of the Company and the Warrantholder and of the Shares
issued or issuable upon the exercise hereof.

                (c)     Definition of Warrantholder. The term Warrantholder

permitted assign of such Warrantholder known to the Company and reflected on the
Company's registry as the holder of this Warrant.

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

                               NOTICE OF EXERCISE

To:     YELLOWBRIX, INC.


        1.      The undersigned hereby elects to purchase __________________
shares of Common Stock/ Series A Preferred Stock ("Stock") of YELLOWBRIX, INC.
(the "Company") pursuant to the terms of the attached Warrant, and tenders
herewith payment of the purchase price, together with an Investment
Representation Statement (see attached form).

        2.      The shares of Stock to be received by the undersigned upon
exercise of the Warrant are being acquired for its own account, not as a nominee
or agent, and not with a view to resale or distribution of any part thereof, and
the undersigned has no present intention of selling, granting any participation
in, or otherwise distributing the same. The undersigned further represents that
it does not have any contract, undertaking, agreement or arrangement with any
person to sell, transfer or grant participation to such person or to any third
person, with respect to the Stock. The undersigned believes it has received all
the information it considers necessary or appropriate for deciding whether to
purchase the Stock.

        3.      The undersigned understands that the shares of Stock and the
shares of the Company's Common Stock into which the Stock is convertible are
characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from the Company in transactions not

                       INVESTMENT REPRESENTATION STATEMENT


PURCHASER:      ABN AMRO Capital (USA) Inc.
                ---------------------------------------

COMPANY:        YELLOWBRIX, INC.

SECURITIES:     Warrant to purchase 188,172 shares of Common Stock /
                Series A Preferred Stock

DATE:


In connection with the purchase of the above-listed Securities, the undersigned,
the Purchaser, represents to the Company the following:

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

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

                (c)     The undersigned further understands that the Securities
must be held indefinitely unless subsequently registered under the Securities
Act or unless an exemption from registration is otherwise available (such as
Rule 144 under the Securities Act). In addition, the undersigned understands
that the certificate evidencing the Securities may be imprinted with a legend
which prohibits the transfer of the Securities unless they are registered or an
exemption from such registration available.

                (d)     The undersigned is familiar with the provisions of Rule
144, promulgated under the Securities Act, which, in substance, permits limited
public resale of "restricted securities" acquired, directly or indirectly, from
the issuer thereof (or from an affiliate of such issuer), in a non-public
offering subject to the satisfaction of certain conditions, including, among
other things: (1) The availability of certain public



                                      -15-
<PAGE>   16


information about the Company; (2) the resale occurring not less than two years
after the party has purchased, and made full payment for, within the meaning of
Rule 144, the securities to be sold; and, in the case of an affiliate, or of a
non-affiliate who has held the securities less than three years; and (3) the
sale being made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker, as said term is defined under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the amount
of securities being sold during any three month period not exceeding the
specified limitation stated therein, if applicable. There can be no assurances
that the requirements of Rule 144 will be met, or that the Securities will ever
be saleable.

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

                (f)     The undersigned further understands that in the event
all of the applicable requirements of Rule 144 are not satisfied registration
under the Securities Act, compliance with some other registration exemption or
the notification to the Company of the proposed disposition by it and the
furnishing to the Company of (i) reasonably detailed information regarding the
disposition, and (ii) opinion of its counsel to the effect that such disposition
will not require registration (the undersigned understands such counsel's
opinion must concur with the opinion by counsel for the Company and the
undersigned must have been informed of such compliance) will be required.


                                        Signature of Purchaser:

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

                                        By:
