                            NET VALUE HOLDINGS, INC.
                          COMMON STOCK PURCHASE WARRANT

         NET VALUE HOLDINGS, INC., a Delaware corporation (the "Company"), for
value received, hereby certifies that Darr Aley (the "Holder") is entitled to
purchase from the Company, at any time or from time to time during the period
specified in Section 2 hereof, 332,416 fully paid and nonassessable shares of
Common Stock, par value $.001, of the Company (the "Common Stock"), at an
exercise price equal to $1.00 per share, subject to adjustment hereunder (the
"Exercise Price"), and subject to the other terms herein. As used herein, the
term "Warrant Shares" means the shares of Common Stock issuable upon exercise of
this Common Stock Purchase Warrant (the "Warrant").

         1. Manner of Exercise; Issuance of Certificates; Payment for Shares.
Subject to the provisions hereof, this Warrant may be exercised by the Holder,
in whole or in part, by the surrender of this Warrant, together with a completed
exercise agreement in the form attached hereto (the "Exercise Agreement"), to
the Company during normal business hours on any business day at the Company's
principal executive offices (or such other office or agency of the Company as it
may designate by notice to the Holder hereof), and upon payment to the Company
in cash, by certified or official bank check or by wire transfer to an account
specified by the Company of the Exercise Price for the Warrant Shares specified
in the Exercise Agreement. The Warrant Shares so purchased shall be deemed to be
issued to the Holder as of the close of business on the date on which this
Warrant shall have been surrendered, the completed Exercise Agreement shall have
been delivered, and payment shall have been made for such shares as set forth
above. Certificates for the Warrant Shares so purchased, representing the
aggregate number of shares specified in the Exercise Agreement, shall be
delivered to the Holder hereof within five business days after this Warrant
shall have been so exercised. The certificates so delivered shall be in such
denominations as may be requested by the Holder hereof and shall be registered
in the name of Holder or such other name as Holder may designate subject to the
transfer restrictions herein and upon payment by Holder of any applicable
transfer taxes. In the event this Warrant is exercised in part, the Company
shall also deliver a new Warrant to the Holder hereof, which Warrant shall be
identical to this Warrant, except that the number of Warrant Shares exercisable
therefor shall be decreased by the number of Warrant Shares so purchased.
<PAGE>

         2. Vesting and Period of Exercise. This Warrant shall vest immediately
as to 192,275 shares of Common Stock and vest pro rata on a monthly basis over
36 months commencing on the date of this Warrant as to the remaining 140,141
shares of Common Stock, provided that, the Holder hereof shall forfeit and
thereafter be unable to exercise any unvested portion of this Warrant following
a breach by Holder of the provisions of Sections 3 or 4 of this Warrant. This
Warrant is exercisable at any time or from time to time on or after the vesting
dates listed above, and before 5:00 p.m., eastern time on the fifth anniversary
of the date of this Warrant (the "Exercise Period").

         3. Non-Disclosure Covenant. The Company and Holder acknowledge that by
virtue of consulting services performed and to be performed by Holder, and by
virtue of Holder's position as a director of the Company, Holder has been and
will continue to be in a relationship of confidence and trust with the Company
and will come into possession of "Confidential Information" (i) owned or
controlled by the Company and its subsidiaries and affiliate companies (as such
term is defined from time to time in periodic reports which the Company files
with the Securities and Exchange Commission); (ii) in the possession of the
Company and its subsidiaries and affiliate companies and belonging to third
parties; or (iii) conceived, originated, discovered or developed, in whole or in
part, by Holder. As used herein "Confidential Information" means trade secrets
and other confidential or proprietary business, technical, personnel or
financial information of the Company, whether or not Holder's work product, in
written, graphic, oral or other tangible or intangible forms, including but not
limited to specifications, samples, records, data, computer programs, drawings,
diagrams, models, consumer names, ID's or e-mail addresses, business or
marketing plans, studies, analyses, projections and reports, communications by
or to attorneys (including attorney-client privileged communications), memos and
other materials prepared by attorneys or under their direction (including
attorney work product), and software systems and processes that are not readily
available to the public, even such items not specifically marked as a trade
secret or confidential, unless the Company advises Holder otherwise in writing
or unless the information has been shared by the Company with entities not bound
by non-disclosure agreements. In consideration of the fees paid, to be paid or
provided to Holder, including the grant of this Warrant, Holder agrees not to
directly or indirectly use or disclose to anyone, either during the term of his
engagement as a consultant to the Company or after the termination of such
engagement, except in the performance of his duties or with the Company's prior
written consent, any Confidential Information of the Company. This
non-disclosure covenant does not apply to information (i) that is disclosed or
becomes public through another source; or (ii) which Holder is required to
disclose pursuant to court order, subpoena or applicable law (provided that
Holder will use reasonable efforts to provide the Company with prompt notice of
any such requests or requirement so that the Company may seek an appropriate
protective order). Holder agrees that in the event of the termination of his
engagement as a consultant to the Company for any reason, Holder will deliver to
the Company, upon request, all property belonging to the Company, including all
documents and materials of any nature pertaining to Holder's engagement with the
Company and will not take with him any documents or materials of any
description, or any reproduction thereof of any description, containing or
pertaining to any Confidential Information.

         4. Non-Competition. During the period commencing on the date of this
Warrant and ending on the date which is the later of one year after the
termination of Holder's engagement as a consultant to the Company or 36 months
after the date of this Warrant (the "Non-Competition Lapse Date"), Holder agrees
that he shall not (a) work for or be interested in any business which serves as

                                       -2-
<PAGE>

a holding company primarily for the purpose of acquiring entities whose products
and services are delivered to consumers over the Internet ("Internet Entities"),
(b) engage or be interested in or receive any compensation from any business in
which the services to be rendered by Holder to such business directly relates to
services or products which are directly competitive with "primary" services or
products offered by the Company or a subsidiary or affiliate company of the
Company at the Non-Competition Lapse Date or (c) induce or attempt to induce
any employee, agent or customer of the Company or any of its subsidiaries or
affiliate companies to terminate or reduce the scope of his, her or its
relationship with the Company. A product or service shall be deemed "primary"
only if such service or product constitutes a primary component of the core
business of the Company, its majority-owned subsidiaries or its affiliate
companies on the Non-Competition Lapse Date. For the purposes of this Agreement,
the term "work for or be interested in" a business means that Holder is a
stockholder, director, officer, employee, partner, individual proprietor, lender
or consultant with that business, but not if his interest is limited solely to
the passive ownership of five percent (5%) or less of any class of the equity or
debt securities of a corporation whose shares are listed for trading on a
national securities exchange or traded in the over-the-counter market. In the
event that any part of this Section 4 is adjudged invalid or unenforceable by
any court of record, board of arbitration or judicial or quasi judicial entity
having jurisdiction thereof by reason of length of time, geographical coverage,
activities covered, or for any other reason, then the invalid or unenforceable
provisions of this covenant shall be deemed reformed and amended to the maximum
extent permissible under applicable law and shall be enforced and enforceable as
so amended in accordance with the intention of the parties as expressed herein.

         5. Certain Agreements of the Company. The Company covenants as follows:

            a. Shares to be Fully Paid. All Warrant Shares shall, upon issuance
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, and charges with respect to the
issue thereof.

            b. Reservation of Shares. During the Exercise Period, the Company
shall at all times have authorized, and reserved for the purpose of issuance
upon exercise of this Warrant, a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

            c. Certain Actions Prohibited. The Company shall not, by amendment
of its certificate of incorporation or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities, or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed by it hereunder, but shall at all
times in good faith assist in the carrying out of all the provisions of this
Warrant and in the taking of all such action as may reasonably be requested by
the Holder of this Warrant in order to protect the exercise privilege of the
Holder of this Warrant against impairment, consistent with the tenor and purpose
of this Warrant. Without limiting the generality of the foregoing, the Company
shall take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

                                       -3-
<PAGE>

            d. Successors and Assigns. This Warrant shall be binding upon any
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all the Company's assets.

         6. Antidilution Provisions. During the Exercise Period, the Exercise
Price and the number of Warrant Shares shall be subject to adjustment from time
to time as provided in this Section 6.

            a. Subdivision or Combination of Common Stock. If the Company at any
time subdivides (by any stock split, stock dividend, recapitalization,
reorganization, reclassification or otherwise) the Common Stock into a greater
number of shares, then, after the record date for effecting such subdivision,
the Exercise Price in effect immediately prior to such subdivision shall be
proportionately reduced and the number of Warrant Shares shall be
proportionately increased. If the Company at any time combines (by reverse stock
split, recapitalization, reorganization, reclassification or otherwise) the
Common Stock into a smaller number of shares, then, after the record date for
effecting such combination, the Exercise Price in effect immediately prior to
such combination shall be proportionately increased and the number of Warrant
Shares shall be proportionately decreased.

            b. Consolidation, Merger or Sale. In case the Company after the date
hereof (a) shall consolidate with or merge into any other entity and shall not
be the continuing or surviving corporation of such consolidation or merger, (b)
shall permit any other entity to consolidate with or merge into the Company and
the Company shall be the continuing or surviving entity but, in connection with
such consolidation or merger, all outstanding shares of Common Stock shall be
changed into or exchanged for stock or other securities of any other entity or
cash or any other property, (c) shall transfer all or substantially all of its
properties or assets to any other person or entity, or (d) shall effect a
capital reorganization or reclassification of the Common Stock (other than a
capital reorganization or reclassification for which adjustment in the Exercise
Price is provided in Section 6(a)), then, and in the case of each such
transaction, proper provision shall be made so that, upon the basis and the
terms and in the manner provided in this Warrant, the Holder, upon the exercise
hereof at any time after the consummation of such transaction, shall be entitled
to receive (at the aggregate Exercise Price in effect at the time of such
consummation for all Common Stock issuable upon such exercise immediately prior
to such consummation), in lieu of the Common Stock issuable upon such exercise
immediately prior to such consummation, the highest amount of securities, cash
or other property to which Holder would have been entitled as a shareholder upon
such consummation if Holder had exercised this Warrant immediately prior
thereto, subject to adjustments (subsequent to such consummation) as nearly
equivalent as possible to the adjustments provided for in this Section 6. The
Company shall not effect any such consolidation, merger, or sale of assets, or
capital reorganization or reclassification unless prior to the consummation
thereof, the continuing or surviving corporation (if other than the Company)
assumes by written instrument the obligations under this Section 6 and the
obligations to deliver to the Holder of this Warrant such securities, cash or
other property as, in accordance with the foregoing provisions, the Holder may
be entitled to acquire.

            c. Distribution of Assets. In case the Company shall declare or make
any distribution of its assets to all Holders of Common Stock as a partial
liquidating dividend, by way

                                       -4-
<PAGE>

of return of capital or otherwise, other than a dividend payable in shares of
Common Stock or in cash out of earnings of the Company, the Holder shall be
entitled upon exercise of this Warrant to receive the amount of cash, securities
or other property that would have been payable to the Holder had Holder been the
Holder of such shares of Common Stock on the record date for the determination
of stockholders entitled to such distribution.

            d. Notice of Adjustment. Upon the occurrence of any event that
requires any adjustment of the Exercise Price, the Company shall give notice
thereof to the Holder, which notice shall state the Exercise Price resulting
from such adjustment and the increase or decrease, if any, in the number of
Warrant Shares, setting forth in reasonable detail the method of calculation and
the facts upon which such calculation is based.

            e. Adjustment of Exercise Price. No adjustment of the Exercise Price
shall be made in an amount less than 1% of the Exercise Price in effect at the
time such adjustment is otherwise required to be made, but any such lesser
adjustment shall be carried forward and shall be made at the time and together
with the next subsequent adjustment which, together with any adjustments so
carried forward, shall amount to not less than 1% of such Exercise Price. In the
event that any adjustment of the Exercise Price as required herein results in a
fraction of a cent, such Exercise Price shall be rounded up to the nearest cent.

            f. No Fractional Shares If any exercise of this Warrant would result
in the issuance of a fractional share of Common Stock, such fractional share
shall be disregarded and the number of shares of Common Stock issuable upon such
exercise shall be the nearest whole number of shares.

            g. Other Notices. In case at any time:

               i. the Company shall declare any dividend upon the Common Stock
payable in shares of stock of any class or make any other distribution (other
than dividends or distributions payable in cash out of retained earnings) to the
holders of the Common Stock;

               ii. the Company shall offer for subscription pro rata to all
holders of the Common Stock any additional shares of stock of any class or other
rights;

               iii. there shall be any capital reorganization of the Company, or
reclassification of the Common Stock or sale of all or substantially all its
assets to another entity; or

               iv. there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the Holder notice of (a) the
date on which the books of the Company shall close or a record shall be taken
for determining the holders of Common Stock entitled to receive any such
dividend, distribution or subscription rights, or for determining the holders of
Common Stock entitled to vote in respect of any such transaction, and (b) the
date (or, if not then known, a reasonable approximation thereof by the Company)
when such transaction shall occur. Such notice shall also specify the date on
which the holders of Common Stock shall be

                                       -5-
<PAGE>

entitled to receive such dividend, distribution or subscription rights or to
exchange their Common Stock for stock or other securities or property
deliverable upon consummation of such transaction. Such notice shall be given at
least 30 days prior to the record date or the date on which the Company's books
are closed in respect thereto. Failure to give any such notice or any defect
therein shall not affect the validity of any action referred to in clauses (i),
(ii), (iii) and (iv) above.

            h. Certain Events. In case any event shall occur as to which
paragraphs (a), (b) or (c) of this Section 6 are not strictly applicable but the
failure to make any adjustment would not fairly protect the rights represented
by this Warrant in accordance with the essential intent of such provisions, the
Company shall give notice of such event as provided in Section 6(d) and shall
make an appropriate adjustment in the Exercise Price and the number of Warrant
Shares to preserve, without dilution, the rights represented by this Warrant.

         7. Tax Obligations. The issuance of certificates for Warrant Shares
upon the exercise of this Warrant shall be made without charge to the Holder for
any issuance tax or other costs in respect thereof; provided that the Holder
shall pay all transfer taxes owed upon the issuance of such shares in the name
of any person or entity designed by the Holder. Upon exercise of the Warrant,
the Company shall have the right to require the Holder to remit to the Company
an amount sufficient to satisfy federal, state and local tax withholding
requirements prior to the delivery of any certificate for shares of Common Stock
purchased pursuant to the Warrant, if in the opinion of counsel to the Company,
such withholding is required under applicable tax laws. If the Holder is
obligated to pay the Company an amount required to be withheld under applicable
tax withholding requirements, then he may pay such amount (i) in cash; (ii) in
the discretion of the Compensation Committee of the Board of Directors, through
the delivery to the Company of previously-owned shares of Common Stock having an
aggregate fair market value equal to the tax obligation, provided that the
previously owned shares delivered in satisfaction of the withholding obligations
must have been held by the Holder for at least six (6) months; (iii) in the
discretion of the Compensation Committee of the Board of Directors, through the
withholding of shares of Common Stock otherwise issuable to the Holder in
connection with the Warrant exercise; or (iv) in the discretion of the
Compensation Committee of the Board of Directors, through a combination of the
procedures set forth in subsections (i), (ii) and (iii) above.

         8. No Rights as a Stockholder. Prior to the exercise of this Warrant,
the Holder hereof, as such, shall not be entitled to any rights of a stockholder
of the Company by virtue of his ownership of this Warrant, including, without
limitation, the right to vote, to consent, to exercise any preemptive right, to
receive any notice of meetings of stockholders for the election of directors of
the Company or any other matter or to receive any notice of any proceedings of
the Company, except as may be specifically provided for herein.

         9. Transfer, Exchange, and Replacement of Warrant.

            a. Replacement of Warrant. Upon 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, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and

                                       -6-
<PAGE>

cancellation of this Warrant, the Company, at its expense, shall execute and
deliver, in lieu thereof, a new Warrant of like tenor.

             b. Cancellation; Payment of Expenses. Upon the surrender of this
Warrant in connection with any transfer or replacement as provided in this
Section 9, this Warrant shall be promptly canceled by the Company. The Company
shall pay all taxes and all other expenses (other than legal expenses, if any,
incurred by the Holder) and charges payable in connection with the preparation,
execution, and delivery of Warrants pursuant to this Section 9.

             c. Register. The Company shall maintain, at its principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the Holder hereof), a register for this Warrant, in which the Company
shall record the name and address of the person in whose name this Warrant has
been issued, as well as the name and address of each transferee and each prior
owner of this Warrant.

             d. Exercise or Transfer Without Registration. If, at the time of
the surrender of this Warrant in connection with any exercise or transfer of
this Warrant, this Warrant (or, in the case of any exercise, the Warrant
Shares), shall not be registered under the Securities Act and under applicable
state securities or blue sky laws, the Company may require, as a condition of
allowing such exercise or transfer, that the Holder furnish to the Company a
written opinion of counsel, which opinion and counsel are acceptable to the
Company, to the effect that such exercise or transfer may be made without
registration under the Securities Act and applicable state securities or blue
sky laws.

             e. Restrictions on Transfer of Shares of Common Stock. The Holder
hereby agrees not to pledge, encumber, sell, assign or transfer (collectively,
"Transfer") the shares of Common Stock which the Holder owns as of the date of
this Warrant until such time as the Board of Directors, in consultation with an
investment banking firm engaged by the Company, determines that any such
Transfer would not have an adverse effect on the public trading market for the
Common Stock, provided that these restrictions on transfer shall lapse 18 months
after the date of this Warrant. The Company may place a restrictive legend
setting forth these restrictions on transfer on any stock certificates
representing these shares of Common Stock. The Company may also place stop
transfer orders on these stock certificates with its transfer agent as long as
these restrictions on transfer remain effective.

         10. Notices. All notices, requests, and other communications required
or permitted to be given or delivered hereunder to the Holder shall be in
writing, and shall be personally delivered, or shall be sent by certified or
registered mail or by recognized overnight mail courier, postage prepaid and
addressed, to the Holder at the address shown for the Holder on the books of the
Company, or at such other address as the Holder shall have furnished to the

overnight mail courier, postage prepaid and properly addressed.

ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF DELAWARE WITHOUT
REGARD TO ITS OR ANY OTHER JURISDICTION'S CONFLICTS OF LAW.

writing signed by the Company and the Holder.
