                 To Subscribe for and Purchase Common Stock of
                             CONNECTED CORPORATION

     THIS CERTIFIES that, for value received, SOFTBANK Holdings Inc. (together
with any subsequent transferees of all or any portion of this Warrant, the
"Holder"), is entitled, upon the terms and subject to the conditions hereinafter
set forth, to subscribe for and purchase from CONNECTED CORPORATION, a Delaware
corporation (hereinafter called the "Company"), at the price hereinafter set
forth in Section 2, up to one hundred thousand five hundred fifty (100,550)
fully paid and non-assessable shares (the "Shares") of the Company's Common
Stock, $.001 par value per share (the "Common Stock").

     1. DEFINITIONS. As used herein the following term shall have the following
meaning:

     "ACT" means the Securities Act of 1933, as amended, or a successor statute
thereto and the rules and regulations of the Securities and Exchange Commission
issued under that Act, as they each may, from time to time, be in effect.

     2. PURCHASE RIGHTS. The purchase rights represented by this Warrant shall
be exercisable by the Holder in whole or in part, in accordance with the
following schedule:

<TABLE>
<CAPTION>
                                  Percentage of the Company's
Anniversary of Company's             Customers Sourced by        Cumulative Maximum Number
First Customer Shipment                  SOFTBANK                 of Warrants Exercisable
-----------------------                  --------                 -----------------------
<S>                                    <C>                           <C>
6 month anniversary                    At least 20%                  10,055 (10%)
12 month anniversary                   At least 20%                  25,138 (25%)
18 month anniversary                   At least 20%                  50,275 (50%)
24 month anniversary                   At least 20%                 100,550 (100%)
</TABLE>

For purposes of the foregoing schedule: the "Company's First Customer
Shipment" shall be deemed to have occurred on the first day of the month next
succeeding the month in which the Company first provided services for a fee to a
customer(s); the "Percentage of the Company's Customers Sourced by SOFTBANK"
shall be determined as follows: on each of the above anniversary dates, the
cumulative number of the Company's customers sourced by SOFTBANK Holdings Inc.
and its then "affiliated companies" (companies in which SOFTBANK has then
invested at least $1,000,000 or any affiliated partnerships managed by
SOFTBANK) ("SOFTBANK"), shall be expressed as a percentage of the total number
of the Company's customers, provided, however, that only fifty (50%) percent of
any Phoenix

<PAGE>   2

Publishing Systems, Inc. customers sourced by SOFTBANK for the Company
shall be deemed to have been sourced by SOFTBANK for purposes hereof, and,
provided further, that any person with which the Company had a relationship
independent of SOFTBANK, prior to such person becoming a customer of the
Company, except as provided herein, shall not be deemed to have been sourced by
SOFTBANK for purposes hereof. Subject to the foregoing, for purposes hereof,
"customers sourced by SOFTBANK" means a person or entity introduced to the
Company by SOFTBANK, who, subsequent to such introduction, becomes a customer
of the Company. With respect to any of the above anniversary dates, in the event
that the number of SOFTBANK sourced customers is less than twenty (20%) percent
of the Company's total customers, the number of Warrants which shall be
exercisable shall be equal to the product of (i) a fraction, the numerator of
which is equal to the percentage of the Company's total customers sourced by
SOFTBANK, and the denominator of which is twenty (20%) percent; and (ii) the
maximum number of Warrants which may be exercised on the anniversary date in
question, as set forth in the above schedule. For example, if, as of the 18
month anniversary date, SOFTBANK sourced customers represent 15% of the
Company's total customers, the number of Warrants exercisable would be
37,706.25, which is equal to (15% + 20%) x 50,275.

     Within 30 days of each of the above anniversary dates, the Company shall
provide SOFTBANK with a certificate, signed by the President of the Company,
stating as of the respective anniversary date the number of the Company's
customers sourced by SOFTBANK, as determined in accordance herewith, as well as
the total number of the Company's customers.

     The purchase rights represented by this warrant shall expire on June 12,
2001.

     Subject to this Section 2, this Warrant may be exercised for Shares at a
price of four dollars ($4.00) per share, subject to adjustment as provided in
Section 6 (the "Warrant Purchase Price").

     3. EXERCISE OF WARRANT. Subject to Section 2 above, the purchase rights
represented by this Warrant may be exercised, in whole or in part and from time
to time, by the surrender of this Warrant and the duly executed Notice of
Exercise (the form of which is attached as Exhibit A) at the principal office of
the Company and by the payment to the Company, by check, of an amount equal to
the then applicable Warrant Purchase Price per share multiplied by the number of
Shares then being purchased. Upon exercise, the Holder shall be entitled to
receive, within a reasonable time, a certificate or certificates, issued in the
Holders name or in such name or names as the Holder may direct, for the number
of Shares so purchased. The Shares so purchased shall be deemed to be issued as
of the close of business on the date on which this Warrant shall have been
exercised.

     4. SHARES TO BE ISSUED; RESERVATION OF SHARES. The Company covenants that
the Shares that may be issued upon the exercise of the purchase rights
represented by this Warrant will, upon issuance in accordance herewith, be fully
paid and non-assessable, and free from all liens and charges with respect to the
issue thereof. During the period within which the purchase rights represented by
the Warrant may be exercised, the Company will at all times have authorized and
reserved, for the purpose of issuance upon exercise of the purchase rights
represented by this Warrant, a sufficient number of shares of its Common Stock
to provide for the exercise of the right represented by this Warrant.

     5. NO FRACTIONAL SHARES. No fractional shares shall be issued upon the
exercise of this Warrant. In lieu thereof, a cash payment shall be made equal to
such fraction multiplied by the fair market value of such shares of Common
Stock, as determined in good faith by the Company's Board of Directors.

other change in the corporate structure of the Company, appropriate adjustments
shall be made by the Board of Directors of the Company (or if the Company is
not the surviving corporation in any such transaction, the Board of Directors
of the surviving corporation) in the aggregate number and kind of shares
subject to this Warrant, and the number and kind of shares and the price per
share then applicable to shares covered by the unexercised portion of this
Warrant.

     7. NO RIGHTS AS SHAREHOLDERS. This Warrant does not entitle the Holder to
any voting rights or other rights as a shareholder of the Company prior to

information, documents and reports as are generally distributed to holders of
the capital stock of the Company concurrently with the distribution thereof to
the shareholders. Upon valid exercise of this Warrant and payment for the Shares
so purchased in accordance with the terms of the Warrant, the Holder or the
Holder's designee, as the case may be, shall be deemed a shareholder of the
Company.

     8. SALE OR TRANSFER OF THE WARRANT AND THE SHARES; LEGEND. The Warrant and
the Shares shall not be sold or transferred unless either (i) they first shall
have been registered under the Act and applicable State Securities laws, or (ii)

        NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE
        REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL
        SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER
        THE SECURITIES ACT OF 1933 OR APPLICABLE STATE SECURITIES LAWS.

Such Warrant and Shares may be subject to additional restrictions on transfer
imposed under applicable state and federal securities law.

     9. MODIFICATIONS AND WAIVERS. This Warrant may not be changed, waived,

decision with respect to an investment in the Company.

     13. BINDING EFFECT ON SUCCESSORS. This Warrant shall be binding upon any
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets, and all of the obligations of
the Company relating to the Shares issuable upon exercise of this Warrant shall
survive the exercise and termination of this Warrant and all of the covenants
and agreements of the Company shall inure to the benefit of the successors and
assigns of the Holder.

     14. GOVERNING LAW. This Warrant shall be construed and enforced in

                 To Subscribe for and Purchase Common Stock of
                             CONNECTED CORPORATION

     THIS CERTIFIES that, for value received, Carl Lazarus (together with any
subsequent transferees of all or any portion of this Warrant, the "Holder"), is
entitled, upon the terms and subject to the conditions hereinafter set forth, to
subscribe for and purchase from CONNECTED CORPORATION, a Delaware corporation
(hereinafter called the "Company"), at the price hereinafter set forth in
Section 2, up to eighteen thousand seven hundred fifty (18,750) fully paid and
non-assessable shares (the "Shares") of the Company's Common Stock, $.001 par
value per share (the "Common Stock").

     1. DEFINITIONS. As used herein the following term shall have the following
meaning:

     "ACT" means the Securities Act of 1933, as amended, or a successor statute
thereto and the rules and regulations of the Securities and Exchange Commission
issued under that Act, as they each may, from time to time, be in effect.

     2. PURCHASE RIGHTS. Subject to this Section 2, the purchase rights
represented by this Warrant shall be exercisable by the Holder in whole or in
part, in forty-eight (48) equal monthly installments, commencing on the date
hereof.

     Subject to the terms hereof, the purchase rights represented by this
Warrant shall expire on June 12, 2001.

     If the Holder's employment with the Company is terminated for any reason
otherwise than by his death or disability (within the meaning of section
22(e)(3) of the Internal Revenue Code of 1986, as amended), he may exercise the
rights which he had hereunder at the time of such termination only within three
months from the date of termination. If his employment is terminated for reason
of disability, such rights may be exercised within twelve months from the date
of termination. Upon the death of the Holder, those entitled to do so by the
Holder's will or the laws of descent and distribution shall have the right, at
any time within twelve months after the date of death, to exercise in whole or
in part any rights which were available to the

<PAGE>   2

Holder at the time of his death, provided, that, in the event the Holder
dies prior to 24 months from the issuance date, the total exercisable purchase
rights shall be changed to be the lesser of (i) fifty (50%) percent of the total
rights granted hereunder (9,375) and (ii) a fraction, the numerator of which is
the total rights granted hereunder multiplied by the number of months from the
issuance date to the date of death plus twelve months; and the denominator of
which is 48. The total exercisable purchase rights include those rights already
exercised, if any. This Warrant shall terminate, and no rights hereunder may be
exercised, after the expiration of the applicable exercise period.

     Subject to this Section 2, this Warrant may be exercised for Shares at a
price of four dollars ($4.00) per share, subject to adjustment as provided in

represented by this Warrant, a sufficient number of shares of its Common Stock
to provide for the exercise of the right represented by this Warrant.

exercise of this Warrant. In lieu thereof, a cash payment shall be made equal to
such fraction multiplied by the fair market value of such shares of Common
Stock, as determined in good faith by the Company's Board of Directors.

shall be any change in the Common Stock of the Company through merger,

surviving corporation) in the aggregate number and kind of shares

                                       -2-
