                             1998 STOCK OPTION PLAN

             EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT

        This Agreement ("Agreement") is made as of ______________, by and
between eGroups, Inc., a Delaware corporation (the "Company"), and
("Purchaser"). To the extent any capitalized terms used in this Agreement are
not defined, they shall have the meaning ascribed to them in the 1998 Stock
Option Plan.

        1. EXERCISE OF OPTION. Subject to the terms and conditions hereof,
Purchaser hereby elects to exercise his or her option to purchase __________
shares of the Common Stock (the "Shares") of the Company under and pursuant to
the Company's 1998 Stock Option Plan (the "Plan") and the Stock Option Agreement
dated <<Date_of_Grant>>, (the "Option Agreement"). The purchase price for the
Shares shall be $<<Exercise_Price_Per_Share>> per Share for a total purchase
price of $_______________. The term "Shares" refers to the purchased Shares and
all securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

        2. TIME AND PLACE OF EXERCISE. The purchase and sale of the Shares under
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement. On such date, the Company
will deliver to Purchaser a certificate representing the Shares to be purchased
by Purchaser (which shall be issued in Purchaser's name) against payment of the
purchase price therefor by Purchaser by (a) check made payable to the Company,
(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, (d) subject to Section 153 of the Delaware General Corporation
Law, delivery of a promissory note in the form attached as Exhibit C to the
Option Agreement (or in any form acceptable to the Company), or (e) a
combination of the foregoing. If Purchaser delivers a promissory note as partial
or full payment of the purchase price, Purchaser will also deliver a Pledge and
Security Agreement in the form attached to Exhibit D to the Option Agreement (or
in any form acceptable to the Company).

        3. LIMITATIONS ON TRANSFER. In addition to any other limitation on
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares except in compliance with the
provisions below and applicable securities laws.

               (a) RIGHT OF FIRST REFUSAL. Before any Shares held by Purchaser
or any transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(a) (the "Right of First Refusal").

                      (i) NOTICE OF PROPOSED TRANSFER. The Holder of the Shares
shall deliver to the Company a written notice (the "Notice") stating: (A) the
Holder's bona fide intention to sell or

   2
otherwise transfer such Shares; (B) the name of each proposed purchaser or other
transferee ("Proposed Transferee"); (C) the number of Shares to be transferred
to each Proposed Transferee; and (D) the terms and conditions of each proposed
sale or transfer. The Holder shall offer the Shares at the same price (the
"Offered Price") and upon the same terms (or terms as similar as reasonably
possible) to the Company or its assignee(s).

                      (ii) EXERCISE OF RIGHT OF FIRST REFUSAL. At any time
within 30 days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (iii) below.

                      (iii) PURCHASE PRICE. The purchase price ("Purchase
Price") for the Shares purchased by the Company or its assignee(s) under this
Section 3(a) shall be the Offered Price. If the Offered Price includes
consideration other than cash, the cash equivalent value of the non-cash
consideration shall be determined by the Board of Directors of the Company in
good faith.

                      (iv) PAYMENT. Payment of the Purchase Price shall be made,
at the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

                      (v) HOLDER'S RIGHT TO TRANSFER. If all of the Shares
proposed in the Notice to be transferred to a given Proposed Transferee are not
purchased by the Company and/or its assignee(s) as provided in this Section
3(a), then the Holder may sell or otherwise transfer such Shares to that
Proposed Transferee at the Offered Price or at a higher price, provided that
such sale or other transfer is consummated within 60 days after the date of the
Notice and provided further that any such sale or other transfer is effected in
accordance with any applicable securities laws and the Proposed Transferee
agrees in writing that the provisions of this Section 3 shall continue to apply
to the Shares in the hands of such Proposed Transferee. If the Shares described
in the Notice are not transferred to the Proposed Transferee within such period,
or if the Holder proposes to change the price or other terms to make them more
favorable to the Proposed Transferee, a new Notice shall be given to the
Company, and the Company and/or its assignees shall again be offered the Right
of First Refusal before any Shares held by the Holder may be sold or otherwise
transferred.

                      (vi) EXCEPTION FOR CERTAIN FAMILY TRANSFERS. Anything to
the contrary contained in this Section 3(a) notwithstanding, the transfer of any
or all of the Shares during Purchaser's lifetime or on Purchaser's death by will
or intestacy to Purchaser's Immediate Family (as defined below) or a trust for
the benefit of Purchaser's Immediate Family shall be exempt from the provisions
of this Section 3(a). "Immediate Family" as used herein shall mean spouse,
lineal descendant or antecedent, father, mother, brother or sister. In such
case, the transferee or other recipient shall receive and hold the Shares so
transferred subject to the provisions of this Section, and there shall be no
further transfer of such Shares except in accordance with the terms of this
Section 3.

               (b) INVOLUNTARY TRANSFER.

                      (i) COMPANY'S RIGHT TO PURCHASE UPON INVOLUNTARY TRANSFER.
In the event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including divorce or death, but
excluding, in the event of death, a transfer to Immediate Family as set forth in
Section 3(a)(vi) above) of all or a portion of the Shares by the record holder
thereof, the Company shall have the right to purchase all of the Shares
transferred at the greater of



                                      -2-
   3
the purchase price paid by Purchaser pursuant to this Agreement or the Fair
Market Value of the Shares on the date of transfer. Upon such a transfer, the
person acquiring the Shares shall promptly notify the Secretary of the Company
of such transfer. The right to purchase such Shares shall be provided to the
Company for a period of 30 days following receipt by the Company of written
notice by the person acquiring the Shares.

                      (ii) PRICE FOR INVOLUNTARY TRANSFER. With respect to any
stock to be transferred pursuant to Section 3(b)(i), the price per Share shall
be a price set by the Board of Directors of the Company that will reflect the
current value of the stock in terms of present earnings and future prospects of
the Company. The Company shall notify Purchaser or his or her executor of the
price so determined within 30 days after receipt by it of written notice of the
transfer or proposed transfer of Shares. However, if the Purchaser does not
agree with the valuation as determined by the Board of Directors of the Company,
the Purchaser shall be entitled to have the valuation determined by an
independent appraiser to be mutually agreed upon by the Company and the
Purchaser and whose fees shall be borne equally by the Company and the
Purchaser.

               (c) ASSIGNMENT. The right of the Company to purchase any part of
the Shares may be assigned in whole or in part to any stockholder or
stockholders of the Company or other persons or organizations; provided,
however, that an assignee, other than a corporation that is the Parent or a 100%
owned Subsidiary of the Company, must pay the Company, upon assignment of such
right, cash equal to the difference between the original purchase price and Fair
Market Value, if the original purchase price is less than the Fair Market Value
of the Shares subject to the assignment.

               (d) RESTRICTIONS BINDING ON TRANSFEREES. All transferees of
Shares or any interest therein will receive and hold such Shares or interest
subject to the provisions of this Agreement. Any sale or transfer of the Shares
shall be void unless the provisions of this Agreement are satisfied.

               (e) TERMINATION OF RIGHTS. The Right of First Refusal and the
Company's right to repurchase the Shares in the event of an involuntary transfer
pursuant to Section 3(b) above shall terminate upon the first sale of Common
Stock of the Company to the general public pursuant to a registration statement
filed with and declared effective by the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Securities Act").

               (f) MARKET STANDOFF AGREEMENT. In connection with the initial
public offering of the Company's securities and upon request of the Company or
the underwriters managing such underwritten offering of the Company's
securities, Purchaser agrees not to sell, make any short sale of, loan, grant
any option for the purchase of, or otherwise dispose of any securities of the
Company (other than those included in the registration) without the prior
written consent of the Company or such underwriters, as the case may be, for
such period of time (not to exceed 180 days) from the effective date of such
registration as may be requested by the Company or such managing underwriters
and to execute an agreement reflecting the foregoing as may be requested by the
underwriters at the time of the Company's initial public offering.

        4. INVESTMENT AND TAXATION REPRESENTATIONS. In connection with the
purchase of the Shares, Purchaser represents to the Company the following:

               (a) Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. Purchaser is
purchasing the Shares for investment for his or her own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act.



                                      -3-
   4
               (b) Purchaser understands that the Shares have not been
registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of
Purchaser's investment intent as expressed herein.

               (c) Purchaser understands that the Shares are "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, Purchaser must hold the Shares indefinitely unless they
are registered with the Securities and Exchange Commission and qualified by
state authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale. Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

               (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

        5. RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

               (a) LEGENDS. The certificate or certificates representing the
Shares shall bear the following legends (as well as any legends required by
applicable state and federal corporate and securities laws):

                             DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION
                             MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION
                             STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL

                             THE COMPANY.

               (b) STOP-TRANSFER NOTICES. Purchaser agrees that, in order to

notations to the same effect in its own records.

               (c) REFUSAL TO TRANSFER. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in

        6. NO EMPLOYMENT RIGHTS. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a Parent or Subsidiary
of the Company, to terminate Purchaser's employment or consulting relationship,
for any reason, with or without cause.

held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith. In the event that the parties cannot reach a
