                                  MCY.COM, INC.

                          Void after September 12, 2005

         1. Issuance. This Warrant is issued to Sapient Corporation,  a Delaware
corporation  ("Sapient") by MCY.COM,  Inc., a Delaware corporation  (hereinafter
with its successors called the "Company") pursuant to that certain Amendment No.
1 dated as of  September  7, 2000  entered  into in  connection  with the Master
Professional  Services  Agreement  dated as of May 22,  2000 by and  between the
Company  and  Sapient  (the  Amendment  and  the  Master  Professional  Services
Agreement referred to collectively as the "Services Contract").

         2.  Purchase  Price;  Number  of  Shares.  Subject  to  the  terms  and
conditions  hereinafter  set forth,  the registered  holder of this Warrant (the
"Holder"),  commencing on the date hereof,  is entitled,  upon surrender of this
Warrant with the subscription form attached hereto or such other form reasonably
acceptable to the Company duly executed,  at the office of the Company,  or such
other location as the Company shall notify the Holder of in writing, to purchase
from the  Company  at a price of $2.25 per share  (the  "Purchase  Price"),  One
Million  Seventy One Thousand Four Hundred  Twenty Eight  (1,071,428)  shares of

         3.      Payment of Purchase Price; Net Issuance; Condition to Exercise.
                 --------------------------------------------------------------

         (a) The  Purchase  Price  shall  be  payable  in cash  by  delivery  of
immediately available funds in the form delivery of a certified check or by wire
transfer to such account designated by the Company.

         (b) "Cashless  Exercise:"  Notwithstanding any provisions herein to the
contrary,  if, at the time of exercise of this  Warrant,  the  Company's  common
stock is listed and is trading on the NASDAQ National Market or any other NASDAQ
market and the fair market  value (as  determined  by the  closing  price of one
share of the  Company's  common  stock at the close of  regular  trading  on the
immediately preceding trading day) of one share of the Company's common stock is
greater than the applicable Purchase Price per share under this Warrant, in lieu
of paying cash upon  exercise of this  Warrant,  the holder may elect to receive
the number of shares of common stock of the Company computed using the following
formula:

          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 with respect to which this
               Warrant is being exercised;

          A =  the fair market value of one share of the Company's common stock;
               and

          B =  then applicable per share Purchase Price under this Warrant

         (c) The Holder of this  Warrant  shall be  entitled  to  exercise  this
Warrant to  purchase  Shares in part or in full at any time or from time to time
upon  achievement  of the "Live" or "Launch"  Date,  as defined in the  Services
Contract (the  "Delivery  Date").  Prior to the Delivery  Date, the Holder shall
have no right to purchase the Shares covered by this Warrant.


         4. Partial Exercise. This Warrant may be exercised in part, and the
Holder shall be entitled to receive a new warrant, which shall be dated as of
the date of this Warrant, covering the number of Shares in respect of which this
Warrant shall not have been exercised.

         5. Issuance Date. The person or persons in whose name or names any
certificate representing Shares is issued hereunder shall be deemed to have
become the holder of record of the Shares represented thereby as at the close of
business on the date this Warrant is exercised with respect to such Shares,
whether or not the transfer books of the Company shall be closed.

         6. Expiration Date. This Warrant shall expire at the close of business
on September 12, 2005, and shall be void thereafter.

         7. Reserved Shares; Valid Issuance. The Company covenants that it will
at all times from and after the date hereof reserve and keep available such
number of its authorized shares of

                                       2
<PAGE>

common stock, free from all preemptive or similar rights therein, as will be
sufficient to permit the exercise of this Warrant in full. The Company further
covenants that any Shares that may be issued pursuant to the exercise of this
Warrant will, upon issuance, be duly and validly issued, fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issuance thereof. The Company represents that when the Shares are issued the
Shares will not be subject to any restriction other than any restriction
required by securities laws.

         8.  Dividends.  If at any time  during  the term of this  Warrant,  the
Company  shall  subdivide the Shares,  by split-up or otherwise,  or combine the
Shares,  or issue additional  Shares in payment of a dividend on the Shares,  or
any similar  transaction  affecting the Shares, the number of Shares issuable on
the exercise of this Warrant shall forthwith be proportionately increased in the
case of a subdivision or dividend, or proportionately decreased in the case of a
combination, and the Purchase Price shall forthwith be proportionately decreased
in the case of a subdivision or dividend,  or  proportionately  increased in the
case of a combination.

         9.  Mergers  and  Reclassifications.  If at any time during the term of
this Warrant  there shall be any  reclassification,  capital  reorganization  or
change of the Shares (other than as a result of a  subdivision,  combination  or
dividend provided for in Section 8 hereof),  or any consolidation of the Company
with,  or merger of the Company  into,  another  corporation  or other  business
organization  (other than a consolidation  or merger in which the Company is the
continuing  corporation  and which  does not result in any  reclassification  or
change  of the  outstanding  Shares),  or any  sale  or  conveyance  to  another
corporation or other business  organization of all or  substantially  all of the
assets  of  the  Company,   then,  as  a  condition  of  such  reclassification,
reorganization,  change,  consolidation,  merger,  sale  or  conveyance,  lawful
provisions shall be made, and duly executed  documents  evidencing the same from
the Company or its  successor  shall be  delivered  to the  Holder,  so that the
Holder  shall  thereafter  have the right to  purchase,  at a total price not to
exceed that  payable  upon the  exercise of this  Warrant in full,  the kind and
amount of shares of stock and other securities and property receivable upon such
reclassification,   reorganization,   change,  consolidation,  merger,  sale  or
conveyance  by a holder of the number of Shares which might have been  purchased
by the  Holder  immediately  prior  to  such  reclassification,  reorganization,
change,  consolidation,  merger,  sale  or  conveyance,  and  in any  such  case
appropriate  provisions shall be made with respect to the rights and interest of
the Holder to the end that the provisions hereof (including without  limitation,
provisions  for the  adjustment  of the Purchase  Price and the number of Shares
issuable  hereunder) shall thereafter be applicable in relation to any shares of
stock or other  securities  and property  thereafter  deliverable  upon exercise
hereof.

         10. Fractional Units. In no event shall any fractional Shares be issued
upon any  exercise of this  Warrant.  If, upon  exercise of this  Warrant in its
entirety,  the Holder would,  except as provided in this Section 10, be entitled
to receive any fractional  Shares,  then the Company shall issue the next higher
number of full  Shares,  issuing a full  Share with  respect to such  fractional
Share.

         11. Notice of Adjustment.  Whenever the Purchase Price is adjusted,  as
herein  provided,  the  Company  shall  promptly  deliver to the Holder a notice
setting forth the Purchase

                                        3
<PAGE>

Price after such adjustment and setting forth a brief statement of the facts
requiring such adjustment.

         12.      Notices of Record Date, Etc.  In the event of:

                  (a) any taking by the  Company  of a record of the  holders of
any class of securities for the purpose of determining  the holders  thereof who
are  entitled to receive any  dividend  or other  distribution,  or any right to
subscribe for,  purchase or otherwise acquire any Shares or any other securities
or property, or to receive any other right,

                  (b) any reclassification of the capital structure of the
Company, capital reorganization of the Company, consolidation or merger
involving the Company, or sale or conveyance of all or substantially all of its
assets, or

                  (c) any voluntary or involuntary dissolution, liquidation or
winding-up of the Company,

                  then and in each such event the Company  will mail or cause to
be  mailed  to the  Holder a notice  specifying  (i) the date on which  any such
record is to be taken for the purpose of such dividend,  distribution  or right,
and stating the amount and character of such dividend, distribution or right, or
(ii) the date on which any such reclassification, reorganization, consolidation,
merger,  sale or conveyance,  dissolution,  liquidation or winding-up is to take
place, and the time, if any is to be fixed, as of which the holders of record in
respect of such event are to be determined. Such notice shall be mailed at least
20 days prior to the date  specified  in such notice on which any such action is
to be taken.

         13. Amendment. The terms of this Warrant may be amended, modified or
waived only with the written consent of the Company and the Holder.

         14. Warrant Register; Transfers, Etc.

                  A. The Company will maintain a register containing the names
and addresses of the registered Holder of the Warrant. The Holder may change its
address as shown on the warrant register by written notice to the Company
requesting such change. Any notice or written communication required or
permitted to be given to the Holder may be given by certified mail or delivered
to the Holder at its address as shown on the warrant register.

                  B. This Warrant may not be transferred by the Holder with
respect to any or all of the Shares purchasable hereunder without the express,
written consent of the Company and in compliance with applicable federal and
state securities laws other than to an affiliated company controlled by or under
common control with the Holder. If the Company consents to any such transfer,
upon surrender of this Warrant to the Company, together with the assignment
hereof properly endorsed, for transfer of this Warrant as an entirety by the
Holder, the Company shall issue a new warrant of the same denomination to the
assignee. Upon surrender of this Warrant to the Company, together with the
assignment hereof properly endorsed, by the Holder for transfer with respect to
a portion of the Shares purchasable hereunder, the Company shall issue a new


                                       4
<PAGE>

warrant to the assignee, in such denomination as shall be requested by the
Holder hereof, and shall issue to such Holder a new warrant covering the number
of Shares in respect of which this Warrant shall not have been transferred.

                  C. In case this Warrant  shall be mutilated,  lost,  stolen or
destroyed,  the Company shall issue a new warrant of like tenor and denomination
and deliver the same (i) in exchange and substitution for and upon surrender and
cancellation  of any  mutilated  Warrant,  or (ii) in lieu of any Warrant  lost,
stolen or destroyed,  upon receipt of evidence  reasonably  satisfactory  to the
Company  of the  loss,  theft  or  destruction  of  such  Warrant  (including  a
reasonably  detailed  affidavit with respect to the  circumstances  of any loss,
theft or destruction) and of indemnity reasonably satisfactory to the Company.

         15. Governing Law. The provisions and terms of this Warrant shall be
governed by and construed in accordance with the internal laws of the State of
Delaware.

         16. Successors and Assigns. This Warrant shall be binding upon the
Company's successors and assigns and shall inure to the benefit of the Holder's
successors, legal representatives and permitted assigns.

         17.  Business  Days. If the last or appointed day for the taking of any
action  required  or the  expiration  of any  right  granted  herein  shall be a
Saturday or Sunday or a legal holiday in Boston, Massachusetts, then such action
may be taken or right may be exercised on the next succeeding day which is not a
Saturday or Sunday or such a legal holiday.

         18.  Registration  Rights. Upon exercise of this Warrant in whole or in
part, the Holder shall be entitled to piggyback registration rights with respect
to all shares of the Company's common stock received upon exercise  thereof.  In
the event that the Company shall propose to register any of its shares of common
stock under the Securities Act of 1933, as amended, the Company will give prompt
written  notice to the Holder of its intent to effect  such  registration.  Upon
receipt of an election to participate in such  registration  by the Holder,  the
Company  will  include in such  registration  all shares of common  stock of the
Company  which the Holder has elected to include.  In the event that the Company
is  reasonably  unable to include  all of the shares of common  stock  which the
Holder has elected to include,  the number of shares of common stock  elected to
be included shall be reduced on a pro rata basis with the other shareholders

                                       5

whose shares are being including in such registration  (other than the Company).
The costs and expenses,  other than underwriting  discounts and commissions with
respect to the common stock, of such registration shall be borne by the Company.
Notwithstanding the foregoing, Sapient's piggyback registration rights hereunder
shall be  subordinate  to those of existing  security  holders in the event of a
cutback in a managed public offering.
