date. Borrower agrees that Lender may rely on any notice given by any Person it
reasonably believes to be an authorized officer of Borrower.

      2.5 Borrower shall have the option to prepay any Note, in whole or in
part, without premium or penalty by paying the principal amount thereon together
with all accrued and unpaid interest with respect to such principal amount, as
of the date of such prepayment. Notwithstanding the foregoing, any such
prepayment by the Borrower shall not affect Lender's right to purchase as
described in Section 8 herein.

      2.6 (a) Notwithstanding any provision in this Agreement, the Note(s), or
any other Loan Document, it is not the parties' intent to contract for, charge
or receive interest at a rate that is greater than the maximum rate permissible
by law which a court of competent jurisdiction shall deem applicable hereto
(which under the laws of the State of Illinois shall be deemed to be the laws
relating to permissible rates of interest on commercial loans) (the "Maximum
Rate"). If the Borrower actually pays Lender an amount of interest, chargeable
on the total aggregate principal Secured Obligations of Borrower under this
Agreement and the Note(s) (as said rate is calculated over a period of time from
the date of this Agreement through the end of time that any principal is
outstanding on the Note(s)), which amount of interest exceeds interest
calculated at the Maximum Rate on said principal chargeable over said period of
time, then such excess interest actually paid by Borrower shall be applied
first, to the payment of principal outstanding on the Note(s); second, after all
principal is repaid, to the payment of Lender's out of pocket costs, expenses,
and professional fees which are owed by Borrower to Lender under this Agreement
or the Loan Documents; and third, after all principal, costs, expenses, and
professional fees owed by Borrower to Lender are repaid, the excess (if any)
shall be refunded to Borrower, and the effective rate of interest will be
automatically reduced to the Maximum Rate.

      (b) In the event any interest is not paid when due hereunder, delinquent
interest shall be added to principal and shall bear interest on interest,
compounded at the rate set forth in Section 2.3.

                                       9
<PAGE>   10

      (c) Upon and during the continuation of an Event of Default hereunder, all
Secured Obligations, including principal, interest, compounded interest, and
reasonable professional fees, shall bear interest at a rate per annum equal to
the rate set forth in Section 2.3 plus five percent (5%) per annum ("Default
Rate").

      (d) If the Borrower has not repaid the outstanding principal amount under
the Loan in its entirety by the Maturity Date (as defined in the applicable
Note(s)), then for each additional month, or portion thereof, thereafter that
the outstanding principal is not paid, Lender shall have the right to purchase
from the Borrower at the applicable Purchase Price (as defined in Section 8.1
hereof), an additional number of shares of Preferred Stock which number shall be
determined by (i) multiplying the outstanding principal amount which is due but
unpaid by three percent (3%) and (ii) dividing the product thereof by the
Purchase Price.

SECTION 3.  SECURITY INTEREST

      As security for the prompt, complete and indefeasible payment when due
(whether at stated payment dates or otherwise) of all the Secured Obligations
and in order to induce Lender to make the Loan(s) upon the terms and subject to
the conditions of the Note(s), Borrower hereby assigns, conveys, mortgages,
pledges, hypothecates and transfers to Lender for security purposes only, and
hereby grants to Lender a security interest in, all of Borrower's right, title

                tangible or intangible and whether now or hereafter owned or
                existing, leased, consigned by or to, or acquired by, Borrower
                and wherever located; and

        (g)     To the extent not otherwise included, all Proceeds of each of
                the foregoing and all accessions to, substitutions and
                replacements for, and rents, profits and products of each of the
                foregoing.

      Notwithstanding the foregoing, in no event shall Collateral include any
Copyrights, Patents, Trademarks, Licenses, or any Intellectual Property.

      Such security interest shall be subordinate to any Permitted Liens.

                00/100 Dollar ($250,000,000.00) fully-diluted pre-money
                valuation of Borrower if the participants in the Next Round
                include only strategic corporate investor(s); or

        (iii)   the price per share determined as follows:

                (a)     If Borrower closes the Next Round on or before November
                        9, 1999, ninety percent (90%) of the purchase price per
                        share of the securities issued or exchanged in the Next
                        Round.

                (b)     If Borrower closes the Next Round after November 9, 1999
                        but on or before December 9, 1999, eighty-five percent
                        (85%) of the price per share of the securities issued or
                        exchanged in the Next Round.

                (c)     If Borrower closes the Next Round after December 9,
                        1999, but on or before February 9, 2000, seventy percent
                        (70%) of the price per share of the securities issued or
                        exchanged in the Next Round.

                (d)     If Borrower closes the Next Round after February 9,
                        1999, but prior to March 1, 2000, sixty-five percent
                        (65%) of the price per share of the securities issued or
                        exchanged in the Next Round.

                (e)     If Borrower closes the Next Round on or after March 1,

                        Million and 00/100 Dollar ($100,000,000.00) pre-money

Provided, that in the case of a Merger Event the price per share shall be
determined under this subsection (iii) as follows:

        (i)     if the Borrower is acquired in the Merger Event for cash or
                other consideration other than equity securities, the price per
                share shall be determined by dividing the aggregate value of
                such consideration by the number of shares of capital stock of
                Borrower eligible to receive such consideration at the time of
                the Merger Event;

        (ii)    if the consideration in the Merger Event is equity securities,
                then the price per share shall be the per-share value assigned
                in the Merger Event to the Borrower's most senior class of stock
                that is eligible to be exchanged in the Merger Event.

                                       18
<PAGE>   19

      The Purchase Option will terminate upon the date fifteen (15) days after
receipt by Lender of notice from Borrower of its Board of Directors' approval of
definitive plans to initiate an Initial Public Offering or Merger Event, subject
to the terms set forth in Section 8.9 hereof.

The number and purchase price of such shares are subject to adjustment as
provided in this Section 8.

      8.2 If the Borrower has not repaid the outstanding principal amount under
a Note in its entirety by the Maturity Date (as defined in the applicable
Note(s)), then for each additional month, or portion thereof, thereafter that
the outstanding principal is not paid, Lender shall have the right to purchase
from the Borrower, at the Purchase Price (adjusted, as set forth and defined in
Section 8.3 herein), an additional amount of Preferred Stock with a value equal
to the product of (x) the outstanding principal amount which is due but unpaid
and (y) three percent (3%).

      8.3 The Purchase Price per share and the number of shares of Preferred
Stock purchasable hereunder are subject to adjustment, as follows:

      (a) If the Borrower at any time shall, by combination, reclassification,
exchange or subdivision of the securities as to which purchase rights under this
Purchase Option exist into the same or a different number of securities of any
other class or classes, this Purchase Option shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Purchase Option immediately prior to such
classification, exchange, subdivision or other change.

      (b) If the Borrower at any time shall combine or subdivide its Preferred
Stock, the Purchase Price shall be proportionately decreased in the case of a
subdivision, or proportionately increased in the case of a combination.

      (c) If the Borrower at any time shall pay a dividend payable in, or make
any other distribution (except any distribution specifically provided for in the
foregoing subsections (a) or (b)) of the Borrower's stock, then the Purchase
Price shall be adjusted, from and after the record date of such dividend or
distribution, to that price determined by multiplying the Purchase Price in
effect immediately prior to such record date by a fraction (i) the numerator of
which shall be the total number of all shares of the Borrower's stock
outstanding immediately prior to such dividend or distribution, and (ii) the
denominator of which shall be the total number of all shares of the Borrower's
stock outstanding immediately after such dividend or distribution. The Lender
shall thereafter be entitled to purchase, at the Purchase Price resulting from
such adjustment, the number of shares of Preferred Stock (calculated to the
nearest whole share) obtained by multiplying the Purchase Price in effect
immediately prior to such adjustment by the number of shares of Preferred Stock
issuable upon the exercise hereof immediately prior to such adjustment and
dividing the product thereof by the Purchase Price resulting from such
adjustment.

      (d) Additional antidilution rights applicable to the authorized and
outstanding Series A and Series B Preferred Stock are as set forth in the
Borrower's Certificate of Incorporation, as amended through the Closing Date, a
true and complete copy of which is

                                       19
<PAGE>   20

attached hereto as Exhibit C (the "CHARTER"). The Borrower shall promptly
provide the Lender with any restatement, amendment, modification or waiver of
the Charter. The Preferred Stock purchasable hereunder shall have the benefit of
the same antidilution rights applicable to such Preferred Stock when authorized
and issued pursuant to Borrower's Charter, as amended, and Borrower shall
provide Lender with all notices and information at the time and to the extent it
is required to do so to the holders of Preferred Stock.

      (e) If: (i) the Borrower shall declare any dividend or distribution upon
its stock, whether in cash, property, stock or other securities; (ii) there
shall be any Merger Event; (iii) there shall be an Initial Public Offering; or
(iv) there shall be any voluntary dissolution, liquidation or winding up of the
Borrower; then, in connection with each such event, the Borrower shall send to
the Lender: (A) at least fifteen (15) days' prior written notice of the date on
which the books of the Borrower shall close or a record shall be taken for such
dividend, distribution, subscription rights (specifying the date on which the
holders of Preferred Stock shall be entitled thereto) or for determining rights
to vote in respect of such Merger Event, dissolution, liquidation or winding up;
(B) in the case of any such dissolution, liquidation or winding up, at least
fifteen (15) days' prior written notice of the date when the same shall take
place (and specifying the date on which the holders of Preferred Stock shall be
entitled to exchange their Preferred Stock for securities or other property
deliverable upon dissolution, liquidation or winding up); and (C) in the case of
a Initial Public Offering or Merger Event, the Borrower shall give the Lender at
least fifteen (15) days written notice prior to the effective date thereof.

      Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Purchase Price, and (v)
the number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Lender, at the address as shown herein, or at such other address as
Lender may subsequently designate by written notice to Borrower.

      (f) Failure to timely provide such notice required by subsection (e) above
shall entitle Lender to retain the benefit of the applicable notice period
notwithstanding anything to the contrary contained in any insufficient notice
received by Lender. The notice period shall begin on the date Lender actually
receives a written notice containing all the information specified above.

      8.5 The Purchase Option is exercisable by the Lender, in whole or in part,
at any time, or from time to time, prior to the earlier of fifteen (15) days
after receipt of notice from Borrower of the Board of Directors' approval of
definitive plans to initiate (i) an Initial Public Offering, or (ii) a Merger
Event. Lender may exercise its Purchase Option by tendering to the Borrower at
its principal office a notice of exercise in the form attached hereto as Exhibit
D (the "NOTICE OF PURCHASE"), duly completed and executed together with payment
in an amount equal to the Purchase Price for that portion of the Purchase Option
so exercised, in cash or by bank cashier's or certified check; provided that
Lender may satisfy all or a portion of the Purchase Price by tender of one or
more Note(s), the outstanding principal and interest of which shall be credited
against the Purchase Price, with the balance, if any, of the Purchase Price
payable in cash or by check as provided above. In such event, the Note(s) so
tendered will be deemed satisfied in full and will be cancelled by the Lender
and the Borrower will have no further obligation to the Lender under such
Note(s).

                                       20
<PAGE>   21

      Promptly upon receipt of the Notice of Purchase and the payment of the
Purchase Price in accordance with the terms set forth below, Borrower shall
execute the acknowledgment of exercise in the form attached hereto as Exhibit E
(the "ACKNOWLEDGMENT OF PURCHASE") indicating the number of shares which remain
subject to future purchases, if any. Subject to Lender's right of withdrawal, no
later than twenty-one (21) days thereafter, the Borrower shall issue to the
Lender a certificate for the number of shares of Preferred Stock purchased.

      8.6 (a) During the term of this Purchase Option, the Borrower will at all
times have authorized and reserved a sufficient number of shares of its
Preferred Stock to provide for the exercise of the rights to purchase Preferred
Stock as provided for herein.

      (b) If any shares of Preferred Stock required to be reserved hereunder
require registration with or approval of any governmental authority under any
Federal or State law (other than any registration under the Securities Act of
1933, as amended ("1933 Act"), as then in effect, or any similar Federal statute
then enforced, or any state securities law, required by reason of any transfer
involved in such purchase), or listing on any domestic securities exchange,
before such shares may be issued upon purchase, the Borrower will, at its
expense and as expeditiously as possible, use its best efforts to cause such
shares to be duly registered, listed or approved for listing on such domestic
securities exchange, as the case may be.

      8.7 No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Purchase Option, but in lieu of such fractional
shares the Borrower shall make a cash payment therefor upon the basis of the
Purchase Price then in effect.

      8.8 This Purchase Option does not entitle the Lender to any voting rights
or other rights as a shareholder of the Borrower prior to the exercise of the
Purchase Option.

      8.9 Borrower shall give Lender at least fifteen (15) days notice of a
Board of Directors' approval of definitive plans to initiate a Merger Event or
an Initial Public Offering of its capital stock pursuant to a registration
statement filed with the Securities and Exchange Commission. In either such
event, Lender shall have the right to exercise its Purchase Option subject to
the successful completion of such Merger Event or Initial Public Offering. If
such closing does not take place, the Borrower shall promptly notify the Lender
that such proposed transaction has been terminated, and the Lender may rescind
any exercise of its Purchase Option promptly after such notice of termination of
the proposed transaction if the exercise of this Purchase Option has occurred
after the Borrower notified the Lender that the Merger Event was proposed.

SECTION 9.  DEFAULT

      The occurrence of any one or more of the following events (herein called
"EVENTS OF DEFAULT") shall constitute a default hereunder and under the Note(s)
and other Loan Documents:

      9.1 Borrower defaults in the payment of any principal, interest or other
Secured Obligation involving the payment of money under this Agreement, the
Note(s) or any of the

                                       21
<PAGE>   22

other Loan Documents, and such default continues for more than five (5) days
after Lender has given written notification thereof; or

      9.2 Borrower defaults in the performance of any other covenant or Secured
Obligation of Borrower hereunder or under the Note(s) or any of the other Loan
Documents, and such default continues for more than twenty (20) days after
Lender has given written notice to Borrower of such default.

      9.3 Any representation or warranty made herein by Borrower shall prove to
have been false or misleading in any material respect on the date it was made;
or

      9.4 Borrower shall make an assignment for the benefit of creditors, or
shall admit in writing its inability to pay its debts as they become due, or
shall file a voluntary petition in bankruptcy, or shall file any petition or
answer seeking for itself any reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar relief under any present or
future statute, law or regulation pertinent to such circumstances, or shall seek
or consent to or acquiesce in the appointment of any trustee, receiver, or
liquidator of Borrower or of all or any substantial part (33-1/3% or more) of
the properties of Borrower; or Borrower or its directors or majority
shareholders shall take any action initiating the dissolution or liquidation of
Borrower; or

      9.5 Sixty (60) days shall have expired after the commencement of an action
by or against Borrower seeking reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar relief under any present or
future statute, law or regulation, without such action being dismissed or all
orders or proceedings thereunder affecting the operations or the business of
Borrower being stayed; or a stay of any such order or proceedings shall
thereafter be set aside and the action setting it aside shall not be timely
appealed; or Borrower shall file any answer admitting or not contesting the
material allegations of a petition filed against Borrower in any such
proceedings; or the court in which such proceedings are pending shall enter a
decree or order granting the relief sought in any such proceedings; or

      9.6 Sixty (60) days shall have expired after the appointment, without the
consent or acquiescence of Borrower, of any trustee, receiver or liquidator of
Borrower or of all or any substantial part of the properties of Borrower without
such appointment being vacated; or

      9.7 The occurrence of any payment default in excess of $100,000 under any
Senior Loan Documents, Excluded Agreements, lease or other promissory note,
agreement for borrowed money or obligation of Borrower which remains uncured for
more than thirty (30) days after Borrower receives written notification thereof.

SECTION 10. REMEDIES

      Upon the occurrence and continuance of any one or more Events of Default,
Lender, at its option, may declare the Note and all of the other Secured
Obligations to be accelerated and immediately due and payable (provided, that
upon the occurrence of an Event of Default of the type described in Sections 9.4
or 9.5, the Note(s) and all of the other Secured Obligations shall automatically
be accelerated and made due and payable without any further act), whereupon the
unpaid principal of and accrued interest on such Note(s) and all other
outstanding Secured Obligations shall become immediately due and payable, and
shall thereafter bear interest at

                                       22
<PAGE>   23

the Default Rate set forth in, and calculated according to, Section 2.3 (c) of
this Agreement. Lender may exercise all rights and remedies with respect to the
Collateral under the Loan Documents or otherwise available to it under
applicable law, including the right to release, hold or otherwise dispose of all
or any part of the Collateral and the right to occupy, utilize, process and
commingle the Collateral.

      After any one or more Events of Default has remained uncured for more than
fifteen (15) days after Lender has given written notice to Borrower of failure
to cure any Event of Default Lender may then, or at any time thereafter and from
time to time, apply, collect, sell in one or more sales, lease or otherwise
dispose of, any or all of the Collateral, in its then condition or following any
commercially reasonable preparation or processing, in such order as Lender may
elect, and any such sale may be made either at public or private sale at its
place of business or elsewhere. Borrower agrees that any such public or private
sale may occur upon five (5) calendar days' prior written notice to Borrower.
Lender may require Borrower to assemble the Collateral and make it available to
Lender at a place designated by Lender which is reasonably convenient to Lender
and Borrower. The proceeds of any sale, disposition or other realization upon
all or any part of the Collateral shall be distributed by Lender in the
following order of priorities:

      First, to Lender in an amount sufficient to pay in full Lender's
      reasonable costs and professionals' and advisors' reasonable fees and
      expenses;

      Second, to Lender in an amount equal to the then unpaid amount of the
      Secured Obligations in such order and priority as Lender may choose in its
      sole discretion; and

      Finally, upon payment in full of all of the Secured Obligations, to
      Borrower or its representatives or as a court of competent jurisdiction
      may direct.

      Lender shall be deemed to have acted reasonably in the custody,
preservation and disposition of any of the Collateral if it complies with the
obligations of a secured party under Section 9207 of the UCC.

      Lender's rights and remedies hereunder are subject to the terms of the
Subordination Agreement.

SECTION 11. MISCELLANEOUS

      11.1 CONTINUATION OF SECURITY INTEREST. This is a continuing Agreement and
the grant of a security interest hereunder shall remain in full force and effect
and all the rights, powers and remedies of Lender hereunder shall continue to
exist until the Secured Obligations are paid in full as the same become due and
payable and until Lender has executed a written termination statement (which
Lender shall promptly execute after full payment of the Secured Obligations
hereunder), reassigning to Borrower, without recourse, the Collateral and all
rights conveyed hereby and returning possession of the Collateral to Borrower.
The rights, powers and remedies of Lender hereunder shall be in addition to all
rights, powers and remedies given by statute or rule of law and are cumulative.
The Purchase of any one or more of the rights, powers and remedies provided
herein shall not be construed as a waiver of or election of remedies with
respect to any other rights, powers and remedies of Lender.

      11.2 SEVERABILITY. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under such law, such provision shall be ineffective only to the extent
and duration of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Agreement.

      11.3 NOTICE. Except as otherwise provided herein, all notices and service
of process required, contemplated, or permitted hereunder or with respect to the
subject matter hereof shall be in writing, and shall be deemed to have been

      11.4 ENTIRE AGREEMENT; AMENDMENTS. This Agreement, the Note(s), and the
other Loan Documents constitute the entire agreement and understanding of the
parties hereto in respect of the subject matter hereof and thereof, and
supersede and replace in their entirety any prior proposals, term sheets,
letters, negotiations or other documents or agreements, whether written or oral,
with respect to the subject matter hereof or thereof (including, without
limitation, Lender's proposal letter dated August 26, 1999, all of which are
merged herein and therein. None of the terms of this Agreement, the Note(s) or
any of the other Loan Documents may be amended except by an instrument executed
by each of the parties hereto.

      11.5 HEADINGS. The various headings in this Agreement are inserted for
convenience only and shall not affect the meaning or interpretation of this
Agreement or any provisions hereof.

      11.6 NO WAIVER. The powers conferred upon Lender by this Agreement are
solely to protect its interest in the Collateral and shall not impose any duty
upon Lender to exercise any such powers. No omission, or delay, by Lender at any
time to enforce any right or remedy reserved to it, or to require performance of
any of the terms, covenants or provisions hereof by Borrower at any time
designated, shall be a waiver of any such right or remedy to which Lender is
entitled, nor shall it in any way affect the right of Lender to enforce such
provisions thereafter.

      11.7 SURVIVAL. All agreements, representations and warranties contained in
this Agreement, the Note(s) and the other Loan Documents or in any document
delivered pursuant hereto or thereto shall be for the benefit of Lender and
shall survive the execution and delivery of this Agreement and the expiration or
other termination of this Agreement.

      11.8 SUCCESSOR AND ASSIGNS. The provisions of this Agreement and the other
Loan Documents shall inure to the benefit of and be binding on Borrower and its
permitted assigns (if any). Borrower shall not assign its obligations under this
Agreement, the Note(s) or any of the other Loan Documents without Lender's
express written consent which consent shall not be unreasonably withheld, and
any such attempted assignment without consent shall be void and of no effect.
Lender may assign, transfer, or endorse its rights hereunder and under the other
Loan Documents without prior notice to Borrower, and all of such rights shall
inure to the benefit of Lender's successors and assigns.

      11.9 FURTHER INDEMNIFICATION. Borrower agrees to pay, and to save Lender
harmless from, any and all liabilities with respect to, or resulting from any
delay in paying, any and all excise, sales or other similar taxes which may be
payable or determined to be payable with respect to any of the Collateral or in
connection with any of the transactions contemplated by this Agreement.

      11.10 GOVERNING LAW. This Agreement, the Note(s) and the other Loan
Documents have been negotiated and delivered to Lender in the State of Illinois,
and shall not become effective until accepted by Lender in the State of
Illinois. Payment to Lender by Borrower of the Secured Obligations is due in the
State of Illinois. This Agreement, the Note(s) and the other Loan Documents
shall be governed by, and construed and enforced in accordance with, the laws of
the State of Illinois, excluding conflict of laws principles that would cause
the application of laws of any other jurisdiction.

      11.11 CONSENT TO JURISDICTION AND VENUE. All judicial proceedings arising
in or under or related to this Agreement, the Note(s) or any of the other Loan
Documents may be brought in any state or federal court of competent jurisdiction
located in the State of Illinois. By execution and delivery of this Agreement,
each party hereto generally and unconditionally: (a) consents to personal
jurisdiction in Cook County, State of Illinois; (b) waives any objection as to
jurisdiction or venue in Cook County, State of Illinois; (c) agrees not to
assert any defense based on lack of jurisdiction or venue in the aforesaid
courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby
in connection with this Agreement, the Note(s) or the

                                       25
<PAGE>   26

other Loan Documents. Service of process on any party hereto in any action
arising out of or relating to this agreement shall be effective if given in
accordance with the requirements for notice set forth in Section 11.3, above and
shall be deemed effective and received as set forth in Section 11.3, above.
Nothing herein shall affect the right to serve process in any other manner
permitted by law or shall limit the right of either party to bring proceedings
in the courts of any other jurisdiction.

      11.12 MUTUAL WAIVER OF JURY TRIAL. Because disputes arising in connection
with complex financial transactions are most quickly and economically resolved
by an experienced and expert person and the parties wish applicable state and
federal laws to apply (rather than arbitration rules), the parties desire that
their disputes be resolved by a judge applying such applicable laws. EACH OF
BORROWER AND LENDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY
OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR
ANY OTHER CLAIM (COLLECTIVELY, "CLAIMS") ASSERTED BY BORROWER AGAINST LENDER OR
ITS ASSIGNEE AND/OR BY LENDER OR ITS ASSIGNEE AGAINST BORROWER. This waiver
extends to all such Claims, including, without limitation, Claims which involve
persons or entities other than Borrower and Lender; Claims which arise out of or
are in any way connected to the relationship between Borrower and Lender; and
any Claims for damages, breach of contract arising out of this Agreement, any
other Loan Document or any of the Excluded Agreements, specific performance, or
any equitable or legal relief of any kind.

      11.13 CONFIDENTIALITY. Lender acknowledges that certain items of
Collateral, including, but not limited to trade secrets, source codes, customer
lists and certain other items of Intellectual Property, and any Financial

ACKNOWLEDGMENT OF RECEIPT OF NOTICE OF EXERCISE OF PURCHASE OPTION
The undersigned eGroups, Inc. ("Borrower") hereby acknowledges receipt of the
"Notice of Purchase" from Comdisco, Inc. ("Lender") to exercise its Purchase
Option with respect to 437,500 shares of the Series D Preferred Stock of
eGroups, Inc., pursuant to the terms of the Subordinated Loan and Security
Agreement dated October 8, 1999, as amended pursuant to the letter dated
November 17, 1999 (the "Agreement"). Borrower further acknowledges that such
shares remain subject to purchase under the terms of the Agreement.

In connection with such Purchase Option the undersigned hereby represents,
warrants and agrees as follows:

(a) All representations and warranties of the Borrower made pursuant to the
Agreement are true and correct in all material respects on and as of the date of
this Acknowledgment with the same effect as though made on and as of this date
(except as set forth in Schedule 1 to this Acknowledgment)

(b) The Preferred Stock issuable upon exercise of the Lender's rights has been
duly and validly reserved and, when issued in accordance with the provisions of
the Purchase Option, will be validly issued, fully paid and non-assessable, and
will be free of any taxes, liens, charges or encumbrances of any nature
whatsoever; provided, however, that the Preferred Stock issuable pursuant to the
Purchase Option may be subject to restrictions on transfer under state and/or
federal securities laws. The Borrower has made available to the Lender true,
correct and complete copies of its Charter and Bylaws, as amended. The issuance
of certificates for shares of Preferred Stock following exercise of the Purchase
Option shall be made without charge to the Lender for any issuance tax in
respect thereof, or other cost incurred by the Borrower in connection with such
purchase and the related issuance of shares of Preferred Stock. The Borrower
shall not be required to pay any tax which may

be payable in respect of any transfer involved and the issuance and delivery of
any certificate in a name other than that of the Lender.

(c) The issuance to Lender of the right to acquire the shares of Preferred
Stock, has been duly authorized by all necessary corporate action on the part of
the Borrower, and the Purchase Option is not inconsistent with the Borrower's
Charter or Bylaws, does not contravene any law or governmental rule, regulation
or order applicable to it, does not and will not contravene any provision of, or
constitute a default under, any material indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound, and the Purchase
Option constitutes a legal, valid and binding agreement of the Borrower,
enforceable in accordance with its terms.

(d) No consent or approval of, giving of notice to, registration with, or taking
of any other action in respect of any state, federal or other governmental
authority or agency is required with respect to the execution, delivery and
performance by the Borrower of its obligations under the Purchase Option, except
for the filing of notices pursuant to Regulation D under the 1933 Act and any
filing required by applicable state securities law, which filings will be
effective by the time required thereby.

(e) The Borrower is not, pursuant to the terms of any other agreement currently
in existence, under any obligation to register under the 1933 Act any of its
presently outstanding securities or any of its securities which may hereafter be
issued.

(f) Subject to the accuracy of the Lender's representations in its Notice, the
issuance of the Preferred Stock upon exercise of the Purchase Option will
constitute a transaction exempt from (i) the registration requirements of
Section 5 of the 1933 Act, in reliance upon Section 4(2) thereof, and (ii) the
qualification requirements of the applicable state securities laws.

(g) If Lender proposes to sell Preferred Stock issuable upon the exercise of the
Purchase Option in compliance with Rule 144 promulgated by the Securities and
Exchange Commission, the Borrower shall furnish to the Lender, within five (5)
days after receipt of a written request, a written statement confirming the
Borrower's compliance with the filing requirements of the Securities and
Exchange Commission as set forth in such Rule, as such Rule may be amended from
time to time.

Borrower acknowledges that Lender has the right to review Schedule 1 to this
Certificate and that Lender may in its sole discretion withdraw its notice of
exercise of Purchase Option within the ten (10) business days after Lender's
receipt of this Acknowledgment.
