Borrower will pay Bank the unpaid principal amount of all Credit Extensions and
interest on the unpaid principal amount of the Credit Extensions

 2.1.1   Equipment Advances.

(a) Subject to the terms and conditions of this Agreement Bank agrees to lend to
Borrower, from time to time prior to the Commitment Termination Date, equipment
advances (each an "Equipment Advance" and collectively the "Equipment Advances")
in an aggregate amount not to exceed the Committed Equipment Line. When repaid,
the Equipment Advances may not be re-borrowed. The proceeds of the Equipment
Advances will be used solely to reimburse Borrower for the purchase of Eligible
Equipment. Each Equipment Advance shall be considered a promissory note
evidencing the amounts due hereunder for all purposes. Bank's obligation to lend
hereunder shall terminate on the earlier of (i) the occurrence and continuance

(c) Bank's obligation to lend the undisbursed portion of the Committed Equipment
Line will terminate if, in Bank's sole discretion, there has been a material
adverse change in the general affairs, management, results of operation,
condition (financial or otherwise) or the prospects of Borrower, whether or not
arising from transactions in the ordinary course of business, or there has been
any material adverse deviation by Borrower from the most recent business plan of
Borrower presented to and accepted by Bank prior to the execution of this
Agreement.

2.2      Interest Rate, Payments.

(a) Principal and Interest Payments On Payment Dates. Borrower will repay the
Equipment Advances on the terms provided in the Loan Supplement Borrower will
make payments monthly in advance of principal and accrued interest for each
Equipment Advance (collectively, "Scheduled Payments"), on the first Business
Day of the month following the Funding Date (or commencing on the Funding Date
if the Funding Date is the first Business Day of the month) with respect to such
Equipment Advance and continuing thereafter during the Repayment Period on the
first Business Day of each calendar month (each a "Payment Date"), in an amount
equal to the Loan Factor multiplied by the Loan Amount for such Equipment
Advance as of such Payment Date. All unpaid principal and accrued interest is
due and payable in full on the last Payment Date with respect to such Equipment
Advance. Payments received after 12:00 noon Pacific time are considered received
at the opening of business on the next Business Day. When a payment is due on a
day that is not a Business Day, the payment is due the next Business Day and
additional fees or interest accrue. An Equipment Advance may only be prepaid in
accordance with Sections 2.2 (e) and 2.2 (g).

(b) Interest Rate. Borrower will pay interest on the unpaid principal amount of
each Equipment Advance from the first Payment Date after the Funding Date of
such Equipment Advance until the Equipment Advance has been paid in full, at the
per annum rate of interest equal to the Basic Rate determined by Bank as of the
Funding Date for each Equipment Advance in accordance with the definition of the
Basic Rate. Any amounts outstanding during the continuance of an Event of
Default shall bear interest at a per annum rate equal to the Basic Rate plus
five percent (5%). If any change in the law increases Bank's expenses or
decreases its return from the Equipment Advances, Borrower will pay Bank upon
request the amount of such increase or decrease.

(c) Interim Payment In addition to the Scheduled Payments, on the Funding Date
for each Equipment Advance (unless the Funding Date is the first Business Day of
the month) Borrower shall pay to Bank, on behalf of Bank, an amount (the
"Interim Payment") equal to the initial Equipment Advance multiplied by the
product of (i) the quotient derived from dividing the initial Loan Factor with
respect to such Equipment Advance by 30, and (ii) the number of days from the
Funding Date of the Equipment Advance until the first Payment Date with respect
to such Equipment Advance.

Borrower will pay, in addition to the unpaid principal and accrued interest and
all other amounts due on such date with respect to such Equipment Advance, an
amount equal to the Final Payment.

(e) Prepayment Upon an Event of Loss. If any Financed Equipment is subject to an
Event of Loss and Borrower is required to or elects to prepay the Equipment
Advance with respect to such Financed Equipment pursuant to Section 6.7, then
such Equipment Advance shall be prepaid to the extent and in the manner provided
in such section.

9       BANK'S RIGHTS AND REMEDIES

9.1     Rights and Remedies.

When an Event of Default occurs and continues Bank may, without notice or
demand, do any or all of the following:

(a) Declare all Obligations immediately due and payable (but if an Event of
Default described in Section 8.5 occurs all Obligations are immediately due and
payable without any action by Bank);

(b) Stop advancing money or extending credit for Borrower's benefit under this
Agreement or under any other agreement between Borrower and Bank;

(c) Settle or adjust disputes and claims directly with account debtors for
amounts, on terms and in any order that Bank considers advisable;

(d) Make any payments and do any acts it considers necessary or reasonable to
protect its security interest in the Collateral. Borrower will assemble the
Collateral if Bank requires and make it available as Bank designates. Bank may
enter premises where the Collateral is located, take and maintain possession of
any part of the Collateral, and pay, purchase, contest, or compromise any Lien
which appears to be prior or superior to its security interest and pay all
expenses incurred. Borrower grants Bank a license to enter and occupy any of its
premises without charge, to exercise any of Bank's rights or remedies;

(e) Apply to the Obligations any (i) balances and deposits of Borrower it holds,
or (ii) any amount held by Bank owing to or for the credit or the account of
Borrower,

(f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale,
advertise for sale, and sell the Collateral; and

(g) Dispose of the Collateral according to the Code.

9.2 Power of Attorney. Effective only when an Event of Default occurs and
continues, Borrower irrevocably appoints Bank as its lawful attorney to: (i)
endorse Borrowers name on any checks or other forms of payment or security; (ii)
sign Borrower's name on any invoice or bill of lading for any Account or drafts
against account debtors, (iii) make, settle, and adjust all claims under
Borrower's insurance policies; (iv) settle and adjust disputes and claims about
the Accounts directly with account debtors, for amounts and on terms Bank
determines reasonable; and (v) transfer the Collateral into the name of Bank or
a third party as the Code permits. Bank may exercise the power of attorney to
sign Borrower's name on

                                      -13-
<PAGE>   12

any documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred. Bank's
appointment as Borrower's attorney in fact, and all of Bank's rights and powers,
coupled with an interest, are irrevocable until all Obligations have been fully
repaid and performed and Bank's obligation to provide Credit Extensions
terminates.

9.3     Accounts Collection.

When an Event of Default occurs and continues, Bank may notify any Person owing
Borrower money of Bank's security interest in the funds and verify the amount of
the Account. Borrower must collect all payments in trust for Bank and, if
requested by Bank, immediately deliver the payments to Bank in the form received
from the account debtor, with proper endorsements for deposit.

9.4     Bank Expenses.

If Borrower fails to pay any amount or furnish any required proof of payment to
third persons, Bank may make all or part of the payment or obtain insurance
policies required in Section 6.5, and take any action under the policies Bank
deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due
and payable, bearing interest at the then applicable rate and secured by the
Collateral. No payments by Bank are deemed an agreement to make similar payments
in the future or Bank's waiver of any Event of Default.

9.5     Bank's Liability for Collateral.

If Bank complies with reasonable banking practices and Section 9-207 of the

                             MASTER LEASE AGREEMENT

MASTER LEASE AGREEMENT (the "Master Lease") dated June 23, 1999 by and between
COMDISCO, INC. ("Lessor") and EGROUPS, INC. ("Lessee").

IN CONSIDERATION of the mutual agreements described below, the parties agree as
follows (all capitalized terms are defined in Section 14.18):

1. Property Leased.

Lessor leases to Lessee all of the Equipment described on each Summary Equipment
Schedule. In the event of a conflict, the terms of the applicable Schedule
prevail over this Master Lease.

2. Term.

On the Commencement Date, Lessee will be deemed to accept the Equipment, will be
bound to its rental obligations for each item of Equipment and the term of a
Summary Equipment Schedule will begin and continue through the Initial Term and
thereafter until terminated by either party upon prior written notice received
during the Notice Period. No termination may be effective prior to the
expiration of the Initial Term.

3. Rent and Payment.

Rent is due and payable in advance on the first day of each Rent Interval at the
address specified in Lessor's invoice. Interim Rent is due and payable when
invoiced. If any payment is not made when due, Lessee will pay a Late Charge on
the overdue amount. Upon Lessee's execution of each Schedule, Lessee will pay
Lessor the Advance specified on the Schedule. The Advance will be credited
towards the final Rent payment if Lessee is not then in default. No interest
will be paid on the Advance.

4. Selection; Warranty and Disclaimer of Warranties.

4.1 Selection. Lessee acknowledges that it has selected the Equipment and
disclaims any reliance upon statements made by the Lessor, other than as set
forth in the Schedule.

4.2 Warranty and Disclaimer of Warranties. Lessor warrants to Lessee that, so
long as Lessee is not in default, Lessor will not disturb Lessee's quiet and
peaceful possession, and unrestricted use of the Equipment. To the extent
permitted by the manufacturer, Lessor assigns to Lessee during the term of the
Summary Equipment Schedule any manufacturer's warranties for the Equipment.
LESSOR MAKES NO OTHER WARRANTY, EXPRESS OR IMPLIED AS TO ANY MATTER WHATSOEVER,
INCLUDING, WITHOUT LIMITATION, THE MERCHANTABILITY OF THE EQUIPMENT OR ITS
FITNESS FOR A PARTICULAR PURPOSE. Lessor is not responsible for any liability,
claim, loss, damage or expense of any kind (including strict liability in tort)
caused by the Equipment except for any loss or damage caused by the willful
misconduct or negligent acts of Lessor. In no event is Lessor responsible for
special, incidental or consequential damages.

5. Title; Relocation or Sublease; and Assignment.

5.1 Title. Lessee holds the Equipment subject and subordinate to the rights of
the Owner, Lessor, any Assignee and any Secured Party. Lessee authorizes Lessor,
as Lessee's agent, and at Lessor's expense, to prepare, execute and file in
Lessee's name precautionary Uniform Commercial Code financing statements showing
the interest of the Owner, Lessor, and any Assignee or Secured Party in the
Equipment and to insert serial numbers in Summary Equipment Schedules as
appropriate. Lessee will, at its expense, keep the Equipment free and clear from
any liens or encumbrances of any kind (except any caused by Lessor) and will
indemnify and hold the Owner, Lessor, any Assignee and Secured Party harmless
from and against any loss caused by Lessee's failure to do so, except where such
is caused by Lessor.

5.2 Relocation or Sublease. Upon prior written notice, Lessee may relocate
Equipment to any location within the continental United States provided (i) the
Equipment will not be used by an entity exempt from federal income tax, and (ii)
all additional costs (including any administrative fees, additional taxes and
insurance coverage) are reconciled and promptly paid by Lessee.

Lessee may sublease the Equipment upon the reasonable consent of the Lessor and
the Secured Party. Such consent to sublease will be granted if: (i) Lessee meets
the relocation requirements set out above, (ii) the sublease is expressly
subject and subordinate to the terms of the Schedule, (iii) Lessee assigns its
rights in the sublease to Lessor and the Secured Party as additional collateral
and security, (iv) Lessee's obligation to maintain and insure the Equipment is
not altered, (v) all financing statements required to continue the Secured
Party's prior perfected security interest are filed, and (vi) Lessee executes
sublease documents acceptable to Lessor.

No relocation or sublease will relieve Lessee from any of its obligations under
this Master Lease and the relevant Schedule.

5.3 Assignment by Lessor. The terms and conditions of each Schedule have been
fixed by Lessor in order to permit Lessor to sell and/or assign or transfer its
interest or grant a security interest in each Schedule and/or the Equipment to a
Secured Party or Assignee. In that event, the term Lessor will mean the Assignee
and any Secured Party. However, any assignment, sale, or other transfer by
Lessor will not relieve Lessor of its obligations to Lessee and will not
materially change Lessee's duties or materially increase the burdens or risks
imposed on Lessee. The Lessee consents to and will acknowledge such assignments
in a written notice given to Lessee. Lessee also agrees that:

(a)     The Secured Party will be entitled to exercise all of Lessor's
rights, but will not be obligated to perform any of the obligations of Lessor.
The Secured Party will not disturb Lessee's quiet and peaceful possession and
unrestricted use of the Equipment so long as Lessee is not in default and the
Secured Party continues to receive all Rent payable under the Schedule; and

(b)     Lessee will pay all Rent and all other amounts payable to the
Secured Party, despite any defense or claim which it has against Lessor. Lessee
reserves its right to have recourse directly against Lessor for any defense or
claim;

(c)     Subject to and without impairment of Lessee's leasehold rights in
the Equipment, Lessee holds the Equipment for the Secured Party to the extent of
the Secured Party's rights in that Equipment.

6. Net Lease; Taxes and Fees.

6.1 Net Lease. Each Summary Equipment Schedule constitutes a net lease. Lessee's
obligation to pay Rent and all other amounts due hereunder is absolute and
unconditional and is not subject to any abatement, reduction, set-off, defense,
counterclaim, interruption, deferment or recoupment for any reason whatsoever.

6.2 Taxes and Fees. Lessee will pay when due or reimburse Lessor for all taxes,
fees or any other charges (together with any related interest or penalties not
arising from the negligence of Lessor) accrued for or arising during the term of
each Summary Equipment Schedule against Lessor, Lessee or the Equipment by any
governmental authority (except only Federal, state, local and franchise taxes on
the capital or the net income of Lessor). Lessor will file all personal property
tax returns for the Equipment and pay all such property taxes due. Lessee will
reimburse Lessor for property taxes within thirty (30) days of receipt of an
invoice.

7. Care, Use and Maintenance; Inspection by Lessor.

7.1 Care, Use and Maintenance. Lessee will maintain the Equipment in good
operating order and appearance, protect the Equipment from deterioration, other
than normal wear and tear, and will not use the Equipment for any purpose other
than that for which it was designed. If commercially available and considered
common business practice for each item of Equipment, Lessee will maintain in
force a standard maintenance contract with the manufacturer of the Equipment, or
another party acceptable to Lessor, and will provide Lessor with a complete copy
of that contract. If Lessee has the Equipment maintained by a party other than
the manufacturer or self maintains, Lessee agrees to pay any costs necessary for
the manufacturer to bring the Equipment to then current release, revision and
engineering change levels, and to re-certify the Equipment as eligible for
manufacturer's maintenance at the expiration of the lease term, provided
re-certification is available and is required by Lessor. The lease term will
continue upon the same terms and conditions until recertification has been
obtained.

7.2 Inspection by Lessor. Upon reasonable advance notice, Lessee, during
reasonable business hours and subject to Lessee's security requirements, will
make the Equipment and its related log and maintenance records available to
Lessor for inspection.

good standing under the laws of the jurisdiction of its incorporation, is duly

Company's business; and has full corporate power and authority to hold property

obligations under the Master Lease and each Schedule.

or, to the knowledge of the Lessee, threatened against or affecting the Lessee
in any court or before any governmental commission, board or authority which, if
adversely determined, will have a material adverse effect on the ability of the
Lessee to perform its obligations under the Master Lease and each Schedule.

(d)     The Equipment is personal property and when subjected to use by the
Lessee will not be or become fixtures under applicable law.

(e)     The Lessee has no material liabilities or obligations, absolute or
contingent (individually or in the aggregate), except the liabilities and
obligations of the Lessee as set forth in the Financial Statements and
liabilities and obligations which have occurred in the ordinary course of
business, and which have not been, in any case or in the aggregate, materially
adverse to Lessee's ongoing business.

(f)     To the best of the Lessee's knowledge, the Lessee owns, possesses,
has access to, or can become licensed on reasonable terms under all patents,
patent applications, trademarks, trade names, inventions, franchises, licenses,
permits, computer software and copyrights necessary for the operations of its
business as now conducted, with no known infringement of, or conflict with, the
rights of others.

(g)     All material contracts, agreements and instruments to which the
Lessee is a party are in full force and effect in all material respects, and are
valid, binding and enforceable by the Lessee in accordance with their respective
terms, subject to the effect of applicable bankruptcy and other similar laws
affecting the rights of creditors generally, and rules of law concerning
equitable remedies.

9. DELIVERY AND RETURN OF EQUIPMENT.

Lessee hereby assumes the full expense of transportation and in-transit
insurance to Lessee's premises and installation thereat of the Equipment. Upon
termination (by expiration or otherwise) of each Summary Equipment Schedule,
Lessee shall, pursuant to Lessor's instructions and at Lessee's full expense
(including, without limitation, expenses of transportation and in-transit
insurance), return the Equipment to Lessor in the same operating order, repair,
condition and appearance as when received, less normal depreciation and wear and
tear. Lessee shall return the Equipment to Lessor at 6111 North River Road,
Rosemont, Illinois 60018 or at such other address within the continental United
States as directed by Lessor, provided, however, that Lessee's expense shall be
limited to the cost of returning the Equipment to Lessor's address as set forth
herein. During the period subsequent to receipt of a notice under Section 2,
Lessor may demonstrate the Equipment's operation in place and Lessee will supply
any of its personnel as may reasonably be required to assist in the
demonstrations.

10. LABELING.

Upon request, Lessee will mark the Equipment indicating Lessor's interest with
labels provided by Lessor. Lessee will keep all Equipment free from any other
marking or labeling which might be interpreted as a claim of ownership.

11. INDEMNITY.

With regard to bodily injury and property damage liability only, Lessee will
indemnify and hold Lessor, any Assignee and any Secured Party harmless from and
against any and all claims, costs, expenses, damages and liabilities, including
reasonable attorneys' fees, arising out of the ownership (for strict liability
in tort only), selection, possession, leasing, operation, control, use,
maintenance, delivery, return or other disposition of the Equipment during the
term of this Master Lease or until Lessee's obligations under the Master Lease
terminate. However, Lessee is not responsible to a party indemnified hereunder
for any claims, costs, expenses, damages and liabilities occasioned by the
negligent acts of such indemnified party. Lessee agrees to carry bodily injury
and property damage liability insurance during the term of the Master Lease in
amounts and against risks customarily insured against by the Lessee on equipment
owned by it. Any amounts received by Lessor under that insurance will be
credited against Lessee's obligations under this Section.

12. RISK OF LOSS.

Effective upon delivery and until the Equipment is returned, Lessee relieves
Lessor of responsibility for all risks of physical damage to or loss or
destruction of the Equipment. Lessee will carry casualty insurance for each item
of Equipment in an amount not less than the Casualty Value. All policies for
such insurance will name the Lessor and any Secured Party as additional insured
and as loss payee, and will provide for at least thirty (30) days prior written
notice to the Lessor of cancellation or expiration, and will insure Lessor's
interests regardless of any breach or violation by Lessee of any representation,
warranty or condition contained in such policies and will be primary without
right of contribution from any insurance effected by Lessor. Upon the execution
of any Schedule, the Lessee will furnish appropriate evidence of such insurance
acceptable to Lessor.

Lessee will promptly repair any damaged item of Equipment unless such Equipment
has suffered a Casualty Loss. Within fifteen (15) days of a Casualty Loss,
Lessee will provide written notice of that loss to Lessor and Lessee will, at
Lessee's option, either (a) replace the item of Equipment with Like Equipment
and marketable title to the Like Equipment will automatically vest in Lessor or
(b) pay the Casualty Value and after that payment and the payment of all other
amounts due and owing with respect to that item of Equipment, Lessee's
obligation to pay further Rent for the item of Equipment will cease.

13. DEFAULT, REMEDIES AND MITIGATION.

13.1 DEFAULT. The occurrence of any one or more of the following Events of
Default constitutes a default under a Summary Equipment Schedule:

(a)     Lessee's failure to pay Rent or other amounts payable by Lessee when
due if that failure continues for five (5) business days after written notice;
or

(b)     Lessee's failure to perform any other term or condition of the
Schedule or the material inaccuracy of any representation or warranty made by
the Lessee in the Schedule or in any document or certificate furnished to the
Lessor hereunder if that failure or inaccuracy continues for ten (10) business
days after written notice; or

(c)     An assignment by Lessee for the benefit of its creditors, the
failure by Lessee to pay its debts when due, the insolvency of Lessee, the
filing by Lessee or the filing against Lessee of any petition under any
bankruptcy or insolvency law or for the appointment of a trustee or other
officer with similar powers, the adjudication of Lessee as insolvent, the
liquidation of Lessee, or the taking of any action for the purpose of the
foregoing; or

(d)     The occurrence of an Event of Default under any Schedule, Summary
Equipment Schedule or other agreement between Lessee and Lessor or its Assignee
or Secured Party.

13.2 REMEDIES. Upon the occurrence of any of the above Events of Default,
Lessor, at its option, may:

(a)     enforce Lessee's performance of the provisions of the applicable
Schedule by appropriate court action in law or in equity;

(b)     recover from Lessee any damages and or expenses, including Default
Costs;

(c)     with notice and demand, recover all sums due and accelerate and
recover the present value of the remaining payment stream of all Rent due under
the defaulted Schedule (discounted at the same rate of interest at which such
defaulted Schedule was discounted with a Secured Party plus any prepayment fees
charged to Lessor by the Secured Party or, if there is no Secured Party, then
discounted at 6%) together with all Rent and other amounts currently due as
liquidated damages and not as a penalty;

(d)     with notice and process of law and in compliance with Lessee's
security requirements, Lessor may enter on Lessee's premises to remove and
repossess the Equipment without being liable to Lessee for damages due to the
repossession, except those resulting from Lessor's, its assignees', agents' or
representatives' negligence; and

(e)     pursue any other remedy permitted by law or equity.

The above remedies, in Lessor's discretion and to the extent permitted by law,
are cumulative and may be exercised successively or concurrently.

13.3 MITIGATION. Upon return of the Equipment pursuant to the terms of Section
13.2, Lessor will use its best efforts in accordance with its normal business
procedures (and without obligation to give any priority to such Equipment) to
mitigate Lessor's damages as described below. EXCEPT AS SET FORTH IN THIS
SECTION, LESSEE HEREBY WAIVES ANY RIGHTS NOW OR HEREAFTER CONFERRED BY STATUTE
OR OTHERWISE WHICH MAY REQUIRE LESSOR TO MITIGATE ITS DAMAGES OR MODIFY ANY OF
LESSOR'S RIGHTS OR REMEDIES STATED HEREIN. Lessor may sell, lease or otherwise
dispose of all or any part of the Equipment at a public or private sale for cash
or credit with the privilege of purchasing the Equipment. The proceeds from any
sale, lease or other disposition of the Equipment are defined as either:

(a)     if sold or otherwise disposed of, the cash proceeds less the Fair
Market Value of the Equipment at the expiration of the Initial Term less the
Default Costs; or

(b)     if leased, the present value (discounted at 3 percent (3%) over the
U.S. Treasury Notes of comparable maturity to the term of the re-lease) of the
rentals for a term not to exceed the Initial Term, less the Default Costs.

Any proceeds will be applied against liquidated damages and any other sums due
to Lessor from Lessee. However, Lessee is liable to Lessor for, and Lessor may
recover, the amount by which the proceeds are less than the liquidated damages
and other sums due to Lessor from Lessee.

14. ADDITIONAL PROVISIONS.

14.1 BOARD ATTENDANCE. One representative of Lessor will have the right to
attend Lessee's corporate Board of Directors meetings and Lessee will give
Lessor reasonable notice in advance of any special Board of Directors meeting,
which notice will provide an agenda of the subject matter to be discussed at
such board meeting. Lessee will provide Lessor with a certified copy of the
minutes of each Board of

                                      -2-
<PAGE>   3

Directors meeting within thirty (30) days following the date of such meeting
held during the term of this Master Lease.

14.2 FINANCIAL STATEMENTS. As soon as practicable at the end of each month (and
in any event within thirty (30) days), Lessee will provide to Lessor the same
information which Lessee provides to its Board of Directors, but which will
include not less than a monthly income statement, balance sheet and statement of
cash flows prepared in accordance with generally accepted accounting principles,
consistently applied (the "Financial Statements"). As soon as practicable at the
end of each fiscal year, Lessee will provide to Lessor audited Financial
Statements setting forth in comparative form the corresponding figures for the
fiscal year (and in any event within ninety (90) days), and accompanied by an
audit report and opinion of the independent certified public accountants
selected by Lessee. Lessee will promptly furnish to Lessor any additional
information (including, but not limited to, tax returns, income statements,
balance sheets and names of principal creditors) as Lessor reasonably believes
necessary to evaluate Lessee's continuing ability to meet financial obligations.
After the effective date of the initial registration statement covering a public
offering of Lessee's securities, the term "Financial Statements" will be deemed
to refer to only those statements required by the Securities and Exchange
Commission.

14.3 OBLIGATION TO LEASE ADDITIONAL EQUIPMENT. Upon notice to Lessee, Lessor
will not be obligated to lease any Equipment which would have a Commencement
Date after said notice if: (i) Lessee is in default under this Master Lease or
any Schedule; (ii) Lessee is in default under any loan agreement, the result of
which would allow the lender or any secured party to demand immediate payment of
any material indebtedness; (iii) there is a material adverse change in Lessee's
credit standing; or (iv) Lessor determines (in reasonable good faith) that
Lessee will be unable to perform its obligations under this Master Lease or any
Schedule.

14.4 MERGER AND SALE PROVISIONS. Lessee will notify Lessor of any proposed
Merger at least sixty (60) days prior to the closing date. Lessor may, in its
discretion, either (i) consent to the assignment of the Master Lease and all
relevant Schedules to the successor entity, or (ii) terminate the Lease and all
relevant Schedules. If Lessor elects to consent to the assignment, Lessee and
its successor will sign the assignment documentation provided by Lessor. If
Lessor elects to terminate the Master Lease and all relevant Schedules, then
Lessee will pay Lessor all amounts then due and owing and a termination fee
equal to the present value (discounted at 6%) of the remaining Rent for the
balance of the Initial Term(s) of all Schedules, and will return the Equipment
in accordance with Section 9. Lessor hereby consents to any Merger in which the
acquiring entity has a Moody's Bond Rating of BA3 or better or a commercially
acceptable equivalent measure of creditworthiness as reasonably determined by
Lessor.

14.5 ENTIRE AGREEMENT. This Master Lease and associated Schedules and Summary
Equipment Schedules supersede all other oral or written agreements or
understandings between the parties concerning the Equipment including, for
example, purchase orders. ANY AMENDMENT OF THIS MASTER LEASE OR A SCHEDULE, MAY
ONLY BE ACCOMPLISHED BY A WRITING SIGNED BY THE PARTY AGAINST WHOM THE AMENDMENT
IS SOUGHT TO BE ENFORCED.

14.6 NO WAIVER. No action taken by Lessor or Lessee will be deemed to constitute
a waiver of compliance with any representation, warranty or covenant contained
in this Master Lease or a Schedule. The waiver by Lessor or Lessee of a breach
of any provision of this Master Lease or a Schedule will not operate or be
construed as a waiver of any subsequent breach.

14.7 BINDING NATURE. Each Schedule is binding upon, and inures to the benefit of
Lessor and its assigns. LESSEE MAY NOT ASSIGN ITS RIGHTS OR OBLIGATIONS.

14.8 SURVIVAL OF OBLIGATIONS. All agreements, obligations including, but not
limited to those arising under Section 6.2, representations and warranties
contained in this Master Lease, any Schedule, Summary Equipment Schedule or in
any document delivered in connection with those agreements are for the benefit
of Lessor and any Assignee or Secured Party and survive the execution, delivery,
expiration or termination of this Master Lease.

14.9 NOTICES. Any notice, request or other communication to either party by the
other will be given in writing and deemed received upon the earlier of (1)
actual receipt or (2) three days after mailing if mailed postage prepaid by
regular or airmail to Lessor (to the attention of "the Comdisco Venture Group")
or Lessee, at the address set out in the Schedule, (3) one day after it is sent
by courier or (4) on the same day as sent via facsimile transmission, provided
that the original is sent by personal delivery or mail by the sending party.

14.10 APPLICABLE LAW. THIS MASTER LEASE HAS BEEN, AND EACH SCHEDULE WILL HAVE
BEEN MADE, EXECUTED AND DELIVERED IN THE STATE OF ILLINOIS AND WILL BE GOVERNED
AND CONSTRUED FOR ALL PURPOSES IN ACCORDANCE WITH THE LAWS OF THE STATE OF
ILLINOIS WITHOUT GIVING EFFECT TO CONFLICT OF LAW PROVISIONS. NO RIGHTS OR
REMEDIES REFERRED TO IN ARTICLE 2A OF THE UNIFORM COMMERCIAL CODE WILL BE
CONFERRED ON LESSEE UNLESS EXPRESSLY GRANTED IN THIS MASTER LEASE OR A SCHEDULE.

14.11 SEVERABILITY. If any one or more of the provisions of this Master Lease or
any Schedule is for any reason held invalid, illegal or unenforceable, the
remaining provisions of this Master Lease and any such Schedule will be
unimpaired, and the invalid, illegal or unenforceable provision replaced by a
mutually acceptable valid, legal and enforceable provision that is closest to
the original intention of the parties.

14.12 COUNTERPARTS. This Master Lease and any Schedule may be executed in any
number of counterparts, each of which will be deemed an original, but all such
counterparts together constitute one and the same instrument. If Lessor grants a
security interest in all or any part of a Schedule, the Equipment or sums
payable thereunder, only that counterpart Schedule marked "Secured Party's
Original" can transfer Lessor's rights and all other counterparts will be marked
"Duplicate."

14.13 LICENSED PRODUCTS. Lessee will obtain no title to Licensed Products which
will at all times remain the property of the owner of the Licensed Products. A
license from the owner may be required and it is Lessee's responsibility to
obtain any required license before the use of the Licensed Products. Lessee
agrees to treat the Licensed Products as confidential information of the owner,
to observe all copyright restrictions, and not to reproduce or sell the Licensed
Products.

14.14 SECRETARY'S CERTIFICATE. Lessee will, upon execution of this Master Lease,
provide Lessor with a secretary's certificate of incumbency and authority. Upon
the execution of each Schedule with a purchase price in excess of $1,000,000,
Lessee will provide Lessor with an opinion from Lessee's counsel in a form
acceptable to Lessor regarding the representations and warranties in Section 8.

14.15 ELECTRONIC COMMUNICATIONS. Each of the parties may communicate with the
other by electronic means under mutually agreeable terms.

14.16 LANDLORD/MORTGAGEE WAIVER. Lessee agrees to provide Lessor with a
Landlord/Mortgagee Waiver with respect to the Equipment. Such waiver shall be in
a form satisfactory to Lessor.

14.17 EQUIPMENT PROCUREMENT CHARGES/PROGRESS PAYMENTS. Lessee hereby agrees that
