                      AGREEMENT AND PLAN OF REORGANIZATION

        This AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made and
entered into as of November 9, 1999 among eGroups, Inc., a Delaware corporation
("eGroups"), EG Acquisition Corporation, a California corporation and a
wholly-owned subsidiary of eGroups ("Merger Sub"), and ONElist, Inc., a
California corporation ("ONElist").

                                    RECITALS

        A. The Boards of Directors of each of ONElist and eGroups and the sole
shareholder of Merger Sub believe it is in the best interests of each company
and their respective shareholders that eGroups acquire ONElist through the
statutory merger of Merger Sub with and into ONElist (the "Merger") and, in
furtherance thereof, have approved the Merger.

        B. Pursuant to the Merger, among other things, and subject to the terms
and conditions of this Agreement, all of the issued and outstanding shares of
capital stock of ONElist and all outstanding options, warrants and other rights
to acquire or receive shares of capital stock of ONElist shall be converted into
the right to receive shares of capital stock of eGroups.

        C. It is the intention of the parties to this Agreement that the Merger
for federal income tax purposes shall qualify as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code"), and for accounting purposes shall qualify for treatment as a pooling of
interests.

        D. ONElist, eGroups and Merger Sub desire to make certain
representations, warranties, covenants and other agreements in connection with
the Merger.

        NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby the parties agree as follows:

                                    ARTICLE I

                                   THE MERGER

        1.1 The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the California Corporations Code (the "California
Code"), Merger Sub shall be merged with and into ONElist, the separate corporate
existence of Merger Sub shall cease, and ONElist shall continue as the surviving
corporation and as a wholly-owned subsidiary of eGroups. ONElist as the
surviving corporation after the Merger is sometimes referred to hereinafter as
the "Surviving Corporation." The Merger shall be consummated pursuant to the
terms of this Agreement, which has been approved and adopted by the respective
Boards of Directors of ONElist and eGroups, and by eGroups, as the sole
shareholder of Merger Sub.



   7

        1.2 Effective Time. Unless this Agreement is earlier terminated pursuant
to Section 8.1, the closing of the Merger (the "Closing") will take place as
promptly as practicable, but no later than five (5) business days following
satisfaction or waiver of the conditions set forth in Article VI, at the offices
of Wilson Sonsini Goodrich & Rosati ("WSGR"), 975 Page Mill Road, Palo Alto,
California, unless another place, time or date is agreed to by eGroups and
ONElist. The date upon which the Closing actually occurs is herein referred to
as the "Closing Date." On or before the Closing Date, the parties hereto shall
cause the Merger to be consummated by filing an Agreement of Merger in
substantially the form attached hereto as Exhibit C (the "Agreement of Merger")
with the Secretary of State of the State of California, in accordance with the
relevant provisions of applicable law (the time of acceptance by the Secretary
of State of the State of California of such filing being referred to herein as
the "Effective Time"). The parties currently intend that the Closing Date will
occur on or prior to November 30, 1999. The parties hereto shall also take such
further actions as may be required by the State of California in connection with
the consummation of the Merger.

        1.3 Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of the California Code.
Without limiting the generality of the foregoing, and subject thereto, at the
Effective Time, all the property, rights, privileges, powers and franchises of
ONElist and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of ONElist and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.

        1.4    Articles of Incorporation; Bylaws.

               (a) Unless otherwise determined by eGroups and ONElist prior to
the Effective Time, at the Effective Time, the Articles of Incorporation of
ONElist shall be amended and restated in full as set forth in Exhibit 1 to the
Agreement of Merger until thereafter amended in accordance with the California
Code and as provided in such Articles of Incorporation.

               (b) Unless otherwise determined by eGroups and ONElist prior to
the Effective Time, at the Effective Time, the Bylaws of ONElist shall be
amended and restated in full such that the Bylaws of the Merger Sub, as in
effect immediately prior to the Effective Time, shall become the Bylaws of
ONElist as the Surviving Corporation until thereafter amended in accordance with
the California Code and as provided in the Articles of Incorporation of the
Surviving Corporation and such Bylaws.

        1.5    Directors and Officers.

               (a) Surviving Corporation. Unless otherwise determined by eGroups
and ONElist prior to the Effective Time, the directors of Merger Sub immediately
prior to the Effective Time shall be the directors of the Surviving Corporation,
each to hold the office of a director of the Surviving Corporation in accordance
with the provisions of the California Code and the Articles of Incorporation and
Bylaws of the Surviving Corporation until their successors are duly elected and
qualified. The officers of Merger Sub immediately prior to the Effective Time
shall be the initial officers of the Surviving Corporation, each to hold office
in accordance with the provisions of the Bylaws of the Surviving Corporation.

is within the actual knowledge of any of the officers or directors of ONElist or
eGroups, as the case may be.

               "Material Adverse Effect" shall mean any change, event or effect
that is materially adverse to the business, assets (including intangible
assets), financial condition or results of operations of ONElist or eGroups, as
applicable.

               "Michael Klein Option" shall mean, assuming the completion of the
Merger and the next round of equity financing of eGroups, the stock option to be
granted to Michael Klein for that number of shares of eGroups Common Stock that,
upon the completion of such equity financing, would bring his total ownership of
eGroups stock to 3.42% of the total outstanding stock on a fully diluted basis.

               "ONElist Capital Stock" shall mean shares of ONElist Common

               "ONElist Common Stock" shall mean shares of common stock of

               "ONElist Options" shall mean all issued and outstanding options

               "ONElist Shareholders" shall mean holders of any shares of
ONElist Capital Stock immediately prior to the Effective Time.

               (b) Calculation Methodology. The parties have agreed to a method
for estimating the Comdisco Securities and the shares issuable upon exercise of
the Michael Klein Option. Such method is defined in a spreadsheet separately
initialed by ONElist and eGroups. Based upon such method and the agreed upon
formulae and methodology in such spreadsheet ONElist and eGroups have jointly
calculated the Exchange Ratio. Shortly before the Effective Time, ONElist and
eGroups agree to jointly recalculate the Exchange Ratio in accordance with such
method after giving effect to any changes in the eGroups Fully-Diluted
Capitalization Number and/or the ONElist Fully-Diluted Capitalization Number
that occur between the date hereof and the Effective Time.

               (c) Effect on ONElist Capital Stock. At the Effective Time, by
virtue of the Merger and without any action on the part of ONElist or the
ONElist Shareholders, each share of ONElist Capital Stock issued and outstanding
immediately prior to the Effective Time (other than any Dissenting Shares, as
defined in Section 1.7 hereof and any shares owned by eGroups, Merger Sub or
ONElist or any direct or indirect wholly owned subsidiary thereof) shall be
canceled and extinguished and shall be converted automatically into the right to
receive, upon surrender of the certificate representing such shares of ONElist
Capital Stock and upon the terms and subject to conditions set forth below and
throughout this Agreement, including, without limitation, Sections 1.6(f), (g)
and (h) hereof (i) in the case of each share of ONElist Common Stock, a number
of shares of eGroups Common Stock equal to the Exchange Ratio and (ii) in the
case of each share of ONElist Preferred Stock, a number of Shares of eGroups
Series C Preferred Stock equal to the Exchange Ratio.

               (d) Assumption of ONElist Options. At the Effective Time, each
outstanding ONElist Option issued pursuant to ONElist's 1998 Stock Plan (the
"ONElist Option Plan") or otherwise, whether vested or unvested, will be assumed
by eGroups in connection with the Merger. Each ONElist Option so assumed by
eGroups under this Agreement shall continue to have, and be subject to, the same
terms and conditions set forth in the ONElist Option Plan and/or as provided in
the respective option agreements immediately prior to the Effective Time
(including, without limitation, any vesting schedule or repurchase rights),
except that (i) each ONElist Option will be exercisable, subject to the same
terms and conditions set forth in the ONElist Option Plan and/or as provided in
the respective option agreements immediately prior to the Effective Time
(including, without limitation, any vesting schedule or repurchase rights), for
that number of whole shares of eGroups Common Stock equal to the product of the
number of shares of ONElist Common Stock that were issuable upon exercise of
such ONElist Option immediately prior to the Effective Time multiplied by the
Exchange Ratio, rounded down to the nearest whole number of shares of eGroups
Common Stock, (ii) the per share exercise price for the shares of eGroups Common
Stock issuable upon exercise of such assumed ONElist Option will be equal to the
quotient determined by dividing the exercise price per share of ONElist Capital
Stock at which such ONElist Option was exercisable immediately prior to the
Effective Time by the Exchange Ratio, rounded up to the nearest whole cent and
(iii) eGroups and its Board of Directors shall be substituted for ONElist and
the Committee



                                       -5-
   11

of ONElist's Board of Directors (including, if applicable, the entire Board of
Directors of ONElist) administering the ONElist Option Plan.

               (e) Option Status. It is the intention of the parties hereto that
the ONElist Options assumed by eGroups following the Closing pursuant to this
Section 1.6 will, to the extent permitted by applicable law, qualify as
incentive stock options as defined in Section 422 of the Code, to the extent any
such ONElist Options qualified as incentive stock options immediately prior to
the Effective Time.

               (f) Adjustments to Exchange Ratio. The Exchange Ratio shall be
equitably adjusted to reflect fully the effect of any stock split, reverse
split, stock dividend (including any dividend or distribution of securities
convertible into eGroups Capital Stock or ONElist Capital Stock),
reorganization, recapitalization or other like change with respect to eGroups
Capital Stock or ONElist Capital Stock occurring after the date hereof and prior
to the Effective Time. Any such change for which a record date is established
shall be deemed for the purposes of this Section 1.6(f) to have occurred on the
record date.

               (g) Fractional Shares. No fractional share of eGroups Common
Stock or eGroups Series C Preferred Stock shall be issued in the Merger. In lieu
thereof, any fractional share shall be rounded to the nearest whole share (with
0.5 being rounded up) of eGroups Common Stock or eGroups Series C Preferred
Stock, as the case may be.

               (h) Cancellation of eGroups-owned and ONElist-owned Stock. At the
Effective Time, by virtue of the Merger and without any action on the part of
any of the parties hereto, each share of ONElist Capital Stock owned by eGroups,
Merger Sub, ONElist or any direct or indirect wholly-owned subsidiary thereof
immediately prior to the Effective Time, shall be cancelled and extinguished
without any conversion thereof.

               (i) Capital Stock of Merger Sub. At the Effective Time, by virtue
of the Merger and without any action on the part of any of the parties hereto,
each share of capital stock of Merger Sub issued and outstanding immediately
prior to the Effective Time shall be converted into and exchanged for one
validly issued, fully paid and nonassessable share of common stock of the
Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership
of any such shares shall continue to evidence ownership of such shares of
capital stock of the Surviving Corporation.

        1.7 Dissenting Shares. "Dissenting Shares" shall mean any shares of
ONElist Capital Stock held by a holder who has demanded and perfected appraisal
rights for such shares in accordance with the California Code and who, as of the
Effective Time, has not effectively withdrawn or lost such appraisal rights. Any
Dissenting Shares shall be converted into the right to receive from the
Surviving Corporation such consideration as may be determined to be due with
respect to each such Dissenting Share pursuant to Chapter 13 of the California
Code; provided, however, that shares of ONElist Capital Stock that are
Dissenting Shares at the Effective Time of the Merger and are held by a holder
who shall, after the Effective Time of the Merger, withdraw his demand for
appraisal or lose his right of appraisal as provided in the California Code,
shall be



                                      -6-
   12

deemed to be converted, as of the Effective Time of the Merger, into the right
to receive consideration in accordance with the procedures specified in Section
1.6(c). ONElist shall give eGroups (i) prompt notice of any written demands for
appraisal, withdrawals of demands for appraisal and any other instruments served
pursuant to the California Code received by ONElist and (ii) the opportunity to
participate in all negotiations and proceedings with respect to demands for
appraisal under the California Code. ONElist will not voluntarily make any
payment with respect to any demands for appraisal and will not, except with the
prior written consent of eGroups, settle or offer to settle any such demands. It
is understood and agreed that the obligation to make any payment in connection
with Dissenting Shares under Chapter 13 of the California Code shall be
exclusively that of the Surviving Corporation and that eGroups shall be under no
obligation to perform and discharge any such obligation or to reimburse or make
any contribution to the capital of the Surviving Corporation to enable it to
perform and discharge any such obligation. eGroups shall give ONElist prompt
notice of any written demands for appraisal, withdrawals of demands for
appraisal and any other instruments served pursuant to the California Code
received by eGroups.

        1.8    Surrender of Certificates.

               (a) Exchange Agent. WSGR shall serve as the exchange agent (the
"Exchange Agent") in the Merger.

               (b) eGroups to Provide Common Stock and Series C Preferred Stock.
Immediately prior to the Effective Time, eGroups shall make available to the
Exchange Agent for exchange in accordance with this Article I, certificates
representing the shares of eGroups Common Stock and eGroups Series C Preferred
Stock issuable to ONElist Shareholders pursuant to Section 1.6 in exchange for
outstanding shares of ONElist Capital Stock.

               (c) Exchange Procedures. As soon as practicable after the Closing
Date, the Surviving Corporation shall cause to be mailed to each ONElist
Shareholder, (i) a letter of transmittal (which shall be in such form and have
such other provisions as eGroups may reasonably specify and shall specify that
delivery shall be effected, and risk of loss and title to the certificates (the
"Certificates") which immediately prior to the Effective Time represent
outstanding shares of ONElist Capital Stock whose shares are converted into the
right to receive such ONElist Shareholder's pro rata portion of the
Consideration Shares pursuant to Section 1.6, shall pass, only upon delivery of
the Certificates to the Exchange Agent) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing such ONElist Shareholder's pro rata portion of the Consideration
Shares. Upon surrender of a Certificate for cancellation to the Exchange Agent
or to such other agent or agents as may be appointed by eGroups, together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, the holder of such Certificate shall be entitled
to receive, and the Exchange Agent shall promptly deliver in exchange therefor,
a certificate bearing the legend set forth in Section 5.2 hereof representing
the number of whole Consideration Shares to which such holder is entitled
pursuant to Section 1.6, and the Certificate so surrendered shall forthwith be
canceled. Until so surrendered, each outstanding Certificate that, prior to the
Effective Time, represented shares of ONElist Capital Stock will be deemed from
and after the Effective Time, for all corporate purposes, other than the



                                      -7-
   13

payment of dividends, to evidence the ownership of the number of full shares of
eGroups Common Stock and/or eGroups Series C Preferred Stock, as the case may
be, into which such shares of ONElist Capital Stock shall have been so
converted.

               (d) Distributions With Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the Effective Time with
respect to eGroups Common Stock or eGroups Series C Preferred Stock, as the case
may be, with a record date after the Effective Time will be paid to the holder
of any unsurrendered Certificate with respect to the shares of eGroups Common
Stock and/or eGroups Series C Preferred Stock represented thereby until the
holder of record of such Certificate shall surrender such Certificate. Subject
to applicable law, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of
eGroups Common Stock and/or eGroups Series C Preferred Stock issued in exchange
therefor, at the time of such surrender, the amount of dividends or other
distributions (without interest) with a record date after the Effective Time
theretofore paid with respect to such whole shares of eGroups Common Stock
and/or eGroups Series C Preferred Stock.

               (e) Transfers of Ownership. If any certificate for shares of
eGroups Common Stock and/or eGroups Series C Preferred Stock is to be issued in
a name other than that in which the Certificate surrendered in exchange therefor
is registered, it will be a condition of the issuance thereof that the
Certificate so surrendered will be properly endorsed and otherwise in proper
form for transfer and that the person requesting such exchange will have paid to
eGroups or any agent designated by it any transfer or other taxes required by
reason of the issuance of a certificate for shares of eGroups Common Stock
and/or eGroups Series C Preferred Stock, as the case may be, in any name other
than that of the registered holder of the Certificate surrendered.

               (f) No Liability. Notwithstanding anything to the contrary in
this Section 1.8, neither the Exchange Agent, the Surviving Corporation nor any
party hereto shall be liable to a holder of shares of eGroups Capital Stock or
ONElist Capital Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

        1.9 No Further Ownership Rights in ONElist Common Stock. All shares of
eGroups Common Stock and eGroups Series C Preferred Stock issued in accordance
with the terms hereof shall be deemed to have been issued in full satisfaction
of all rights pertaining to shares of ONElist Capital Stock outstanding prior to
the Effective Time, and there shall be no further registration of transfers on
the records of the Surviving Corporation of shares of ONElist Capital Stock
which were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this Article I.

        1.10 Lost, Stolen or Destroyed Certificates. In the event any
Certificates evidencing shares of ONElist Capital Stock shall have been lost,
stolen or destroyed, the Exchange Agent shall issue in exchange for such lost,
stolen or destroyed Certificates, upon the making and delivery of an affidavit
of that fact by the holder thereof, such shares of eGroups Common Stock and/or
eGroups Series C Preferred Stock as may be required pursuant to Section 1.6;
provided, however, that eGroups may, in its discretion and as a condition
precedent to the issuance thereof, require the owner



                                      -8-
   14

of such lost, stolen or destroyed Certificates to deliver a bond in such sum as
it may reasonably direct as indemnity against any claim that may be made against
eGroups or the Exchange Agent with respect to the Certificates alleged to have
been lost, stolen or destroyed.

        1.11 Tax and Accounting Consequences. It is intended by the parties
hereto that the Merger shall (i) constitute a reorganization within the meaning
of Section 368 of the Code and (ii) qualify for accounting treatment as a
pooling of interests. The parties hereto adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Income Tax Regulations. Each party has consulted with its own tax
advisers and accountants with respect to the tax and accounting consequences of
the Merger.

        1.12 Taking of Necessary Action; Further Action. If, at any time after
the Effective Time, any such further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Surviving Corporation with
full right, title and possession to all assets, property, rights, privileges,
powers and franchises of ONElist and Merger Sub, the officers and directors of
ONElist and Merger Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.

                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF ONELIST

        As of the date hereof, ONElist hereby represents and warrants to eGroups
and Merger Sub, subject to such exceptions as are specifically disclosed in the
disclosure schedules supplied by ONElist to eGroups dated as of the date hereof
and attached hereto as Exhibit E (the "ONElist Schedules"), as follows:

        2.1 Organization of ONElist. ONElist is a corporation duly organized,
validly existing and in good standing under the laws of the State of California.
ONElist has the corporate power to own its properties and to carry on its
business as now being conducted. ONElist is duly qualified to do business and in
good standing as a foreign corporation in each jurisdiction in which the failure
to be so qualified would have a Material Adverse Effect on ONElist. ONElist has
delivered a true and correct copy of its Articles of Incorporation and Bylaws,
each as amended to date, to eGroups.

        2.2    ONElist Capital Structure.

               (a) The authorized capital stock of ONElist consists of
10,000,000 shares of authorized Common Stock, no par value, of which 2,457,429
shares are issued and outstanding; 2,400,000 shares of authorized Series A
Preferred Stock, no par value, of which 2,330,665 are issued and outstanding.
The ONElist Capital Stock is held of record by the persons, with the addresses

shares of ONElist Capital Stock are duly authorized, validly issued, fully paid
and non-assessable and not subject to preemptive rights created by statute, the
Articles of Incorporation or Bylaws of ONElist or any material agreement to
which ONElist is a party or by which it is bound.



                                      -9-
   15

               (b) ONElist has reserved 1,665,000 shares of ONElist Common Stock
for issuance to directors, employees and consultants pursuant to the ONElist
Option Plan, of which 819,322 shares are subject to outstanding, unexercised
options and 444,928 shares remain available for future grant. All of the ONElist
Options have been duly authorized and validly issued, as applicable, in

laws. Schedule 2.2(b) sets forth for each outstanding ONElist Option (i) the
name of the holder of such security, (ii) the number of shares of capital stock
subject to such security, (iii) the exercise price of such security, (iv) the
date of grant of such security, (v) the date on which such security expires, and
(vi) whether the exercisability of such security will be accelerated and become
exercisable by reason of the transactions contemplated by this Agreement. Except
as set forth in Schedule 2.2(b), there are no options, warrants, calls, rights,
commitments or agreements of any character, written or oral, to which ONElist is
a party or by which it is bound obligating ONElist to issue, deliver, sell,
repurchase or redeem, or cause to be issued, delivered, sold, repurchased or
redeemed, any shares of the capital stock of ONElist or obligating ONElist to
grant, extend, accelerate the vesting of, change the price of, otherwise amend
or enter into any such option, warrant, call, right, commitment or agreement.
The holders of ONElist Options have been or will be given, or shall have
properly waived, any required notice prior to the Merger, and all such rights
will be terminated at or prior to the Effective Time. As a result of the Merger,
eGroups will be the record and sole beneficial owner of all ONElist Capital
Stock and all rights to acquire or receive ONElist Capital Stock.

        2.3 Subsidiaries. Except as set forth on Schedule 2.3, ONElist does not
have any subsidiaries and does not otherwise own and has never otherwise owned
any shares of capital stock or any interest in, or control, directly or
indirectly, any other corporation, partnership, limited liability company,
association, joint venture or other business entity.

        2.4 Authority. Subject only to the requisite approval of the Merger and
this Agreement by ONElist's shareholders, ONElist has all requisite corporate
power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of ONElist, subject
only to the approval of the Merger by ONElist's shareholders. ONElist's Board of
Directors has unanimously approved the Merger and this Agreement. This Agreement
has been duly executed and delivered by ONElist and constitutes the valid and
binding obligation of ONElist, enforceable in accordance with its terms (except
in all cases as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, receivership, conservatorship, moratorium, or
similar laws affecting the enforcement of creditors' rights generally and except
that the availability of the equitable remedy of specific performance or
injunctive relief is subject to the discretion of the court before which any
proceeding may be brought). Except as set forth on Schedule 2.4, subject only to
the approval of the Merger and this Agreement by ONElist's shareholders, the
execution and delivery of this Agreement by ONElist does not, and, as of the
Effective Time, the consummation of the transactions contemplated hereby will
not, conflict with, or result in any violation of, or default under (with or
without notice or lapse of time, or both), or give rise to a right of
termination, cancellation or acceleration of any obligation or loss of any
benefit under (any such event, a "ONElist Conflict") (i) any provision of the
Articles of Incorporation or Bylaws of ONElist or (ii) any material mortgage,
indenture, lease, contract or



                                      -10-
   16

other material agreement or instrument, permit, concession, franchise, license,
judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to ONElist or its properties or assets. No consent, waiver, approval, order or
authorization of, or registration, declaration or filing with, any court,
administrative agency or commission or other federal, state, county, local or
foreign governmental authority, instrumentality, agency or commission

labor practices within the meaning of the National Labor Relations Act which
would, individually or in the aggregate, directly or indirectly result in a

a government or political subdivision thereof.

               (b) ONElist has no Knowledge of any action taken or agreed to be
taken by ONElist or any Affiliate of ONElist nor has any Knowledge of any fact
or circumstance that is reasonably likely to (a) prevent the Merger from
qualifying for pooling-of-interests accounting treatment, or (b) materially
impede or delay receipt of any consents of regulatory authorities referred to in
Section 6.1(j).

        2.22 Year 2000 Compliance. All of ONElist's products and services

the same manner and with the same functionality, data integrity and performance
as the products record, store,

made by ONElist (as modified by the ONElist Schedules), nor any statement made

agree to be similarly bound) any securities of eGroups held by it at any time
during such period except Common Stock included in such registration; provided,
however that

                      (i) such agreement shall be applicable only to the first
such registration statement of eGroups which covers common stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;
and

efforts to obtain the consents, waivers and approvals under any of the eGroups

the Effective Time under the ONElist Benefit Plans.

        5.12 Accounting and Tax Treatment. Each of the parties undertakes and
agrees to use its reasonable efforts to cause the Merger, and to take no action

Time:

               (a) by mutual consent of ONElist and eGroups;

               (b) by eGroups or ONElist if: (i) the Effective Time has not
occurred before 5:00 p.m. (Pacific time) on December 31, 1999 (provided that the
right to terminate this Agreement under this clause 8.1(b)(i) shall not be
available to any party whose failure to use its commercially reasonable efforts
to fulfill any obligation hereunder has been the cause of, or resulted in, the
failure of the Effective Time to occur on or before such date); (ii) there shall
be a final nonappealable order of a federal or state court in effect preventing
consummation of the Merger; or (iii) there shall be any statute, rule,
regulation or order enacted, promulgated or issued or deemed applicable to the
Merger by any governmental entity that would make consummation of the Merger
illegal;

               (c) by eGroups or ONElist if there shall be any action taken, or
any statute, rule, regulation or order enacted, promulgated or issued or deemed
applicable to the Merger, by any Governmental Entity, which would: (i) prohibit
eGroups' or ONElist's ownership or operation of all or any portion of the
business of ONElist or (ii) compel eGroups or ONElist to dispose of or hold
separate all or a portion of the business or assets of ONElist or eGroups as a
result of the Merger;

               (d) by eGroups if it is not in material breach of its obligations
under this Agreement and there has been a material breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of
ONElist and (i) such breach has not been cured within fifteen (15) days after
written notice to ONElist (provided that, no cure period shall be required for a
breach which by its nature cannot be cured), and (ii) as a result of such breach
the conditions set forth in Section 6.3(a) or 6.3(b), as the case may be, would
not then be satisfied; or

               (e) by ONElist if it is not in material breach of its obligations
under this Agreement and there has been a material breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of
eGroups or Merger Sub and (i) such breach has not been cured within fifteen (15)
days after written notice to eGroups (provided that, no cure period shall be
required for a breach which by its nature cannot be cured), and (ii) as a result
of such breach the conditions set forth in Section 6.2(a) or 6.2(b), as the case
may be, would not then be satisfied.

        Where action is taken to terminate this Agreement pursuant to this
Section 8.1, it shall be sufficient for such action to be authorized by the
Board of Directors (as applicable) of the party taking such action.

        8.2 Effect of Termination. In the event of termination of this Agreement
as provided in Section 8.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of eGroups, Merger Sub or
ONElist, or their respective officers, directors or shareholders, provided that
each party shall remain liable for any breaches of this Agreement prior to its
termination; and provided further that, the provisions of Sections 5.4, 5.5 and
8.2 and Article IX of this Agreement shall remain in full force and effect and
survive any termination of this Agreement.

        8.3 Amendment. Except as is otherwise required by applicable law after
the shareholders of ONElist and the stockholders of eGroups approve this
Agreement, this Agreement may be amended by the parties hereto at any time by
execution of an instrument in writing signed on behalf of each of the parties
hereto.

        8.4 Extension; Waiver. At any time prior to the Effective Time, eGroups
and Merger Sub, on the one hand, and ONElist, on the other, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

counterparts have been signed by each of the parties and delivered to the other
party, it being understood that all parties need not sign the same counterpart.

        9.4 Entire Agreement; Assignment. This Agreement, the Schedules and
Exhibits hereto, and the documents and instruments and other agreements among
the parties hereto referenced herein: (a) constitute the entire agreement among
the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with

other person any rights or remedies hereunder (except with respect to Section

        9.5 Severability. In the event that any provision of this Agreement or
the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and

represented by counsel during the negotiation and execution of this Agreement

construction providing that ambiguities in an agreement or other document will

        9.9 Specific Performance. The parties hereto agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties shall be entitled to an
injunction or injunctions to prevent breaches of this Agreement and to enforce
specifically the terms and provisions hereof in any court of the United States
or any state having jurisdiction, this being in addition to any other remedy to
which they are entitled at law or in equity.
