                                    SUBLEASE

          THIS SUBLEASE ("Sublease") is made and entered into as of the 18th
day of September, 2002, by and between 101 COMMUNICATIONS, LLC, a Delaware
limited liability company ("Sublandlord") and iPAYMENT, INC., a Tennessee
corporation ("Subtenant").

                                    RECITALS

     A.   Catellus Finance 1, L.L.C., a Delaware limited liability company
("Master Landlord"), as landlord, and Sublandlord, as tenant, entered into that
certain Office Lease dated as of July 21, 1999, pursuant to which Master
Landlord leased to Sublandlord and Sublandlord leased from Master Landlord
approximately 21,463 rentable square feet of space known as Suite 101 (the
"Premises") in the building located at 9121 Oakdale Avenue, in Chatsworth,
California (the "Building"). The Office Lease was amended pursuant to that
certain First Amendment to Office Lease, dated as of June 18, 2000, by which an
additional 10,929 rental square feet being located on the Second Floor of the
Building were added to the Lease (the "Additional Premises") as shown on
Schedule 1 of the First Amendment. The Office Lease was further amended by that
certain Second Amendment to Office Lease dated as of February 26, 2001. The
Office Lease as amended to date is referred to herein as the "Master Lease." A
true and complete copy of the Master Lease is attached to this Sublease as
EXHIBIT A and made a part hereof.

     B.   Subtenant desires to sublease from Sublandlord and Sublandlord
desires to sublease to Subtenant, a portion of the Additional Premises located
on the second floor of the Building consisting of approximately 4,661 rentable
square feet, as depicted on EXHIBIT B to this Sublease (the "Subpremises") upon
the terms, covenants and conditions set forth herein.

                                   AGREEMENT

          NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Sublandlord and Subtenant agree
as follows:

          1.   Capitalized Terms. All capitalized terms used in this Sublease
and not otherwise defined herein shall have the same meanings given such terms
in the Master Lease.

          2.   Demise. Sublandlord hereby subleases to Subtenant and Subtenant
hereby subleases from Sublandlord the Subpremises.

          3.   Term. The "Term" of this Sublease shall commence on the later of
(a) October 1, 2002; or (b) ten (10) days after the date that Sublandlord
delivers Master Landlord's written consent to this Sublease to Subtenant, or
such other date to which the parties mutually agree (the "Sublease Commencement
Date"). Sublandlord agrees to vacate the Subpremises and deliver possession
thereof to Subtenant on or before the date that Sublandlord delivers Master
Landlord's written consent to this Sublease to Subtenant. Subtenant shall have
the right to access the Subpremises from and after the execution date to enable
Subtenant to perform measurements and space planning, but not for construction.
From and after the date that Sublandlord delivers Master Landlord's written
consent to the Sublease to Subtenant and continuing up to the Sublease
Commencement Date, Subtenant shall have the right to enter upon

                                       1

<PAGE>
and install its data equipment, trade fixtures and furniture and, subject to any
notice and consent provisions of the Master Lease, if any, make the alterations
identified in EXHIBIT C hereto. Such early entry will not cause the Base Rent
and other Rent under this Sublease to commence, but shall otherwise be subject
to all the other terms and conditions of this Sublease, including without
limitation thereto, evidence of the insurance required by the terms of this
Sublease and the indemnity provisions of Section 10. The Term shall expire on
August 29, 2004, the day before the expiration date of the term  of the Master
Lease, unless sooner terminated as provided in this Sublease or pursuant to the
terms of the Master Lease. Sublandlord estimates that it will be in a position
to deliver Master Landlord's written consent to this Sublease to Subtenant on or
about September 21, 2002. If Sublandlord is unable to deliver Master Landlord's
written consent to this Sublease to Subtenant by October 1, 2002, then this
Sublease shall not be void or voidable and Sublandlord shall not be liable to
Subtenant, but the Sublease Commencement Date (and Subtenant's obligation to pay
Base Rent and other Rent under this Sublease) shall be delayed until Master
Landlord's written consent to this Sublease is delivered to Subtenant, provided,
however, that if the Master Landlord fails to consent to this Sublease by
October 10, 2002, then either party shall have the right to terminate this
Sublease upon written notice to the other party prior to the receipt of such
consent from the Master Landlord and Sublandlord shall return any prepaid Rent
and Security Deposit to Subtenant, and the parties shall be released from any
obligations or rights hereunder. The terms and provisions of this Section 3
shall constitute the parties' entire agreement regarding the Term of this
Sublease and the provisions of Section 2 of the Master Lease are not deemed to
be incorporated into this Sublease.

          4. Base Rent. During the Term of this Sublease, Subtenant shall pay to
Sublandlord Base Rent in the following amounts: (i) the Base Rent for the period
from the Sublease Commencement Date trough September 30, 2003, will be $3,495.75
per month; and (ii) the Base Rent for the period October 1, 2003, through August
29, 2004, will be $3,600.62 per month. All payments of Base Rent by Subtenant
hereunder shall be paid by Subtenant to Sublandlord at "Tenant's Address" set
forth in the Master Lease, or at such other address as selected by Sublandlord
from time to time on written notice to Subtenant. If the Term commences (or
ends) on a date other than the first (or last) day of a month, Base Rent shall
be prorated on the basis of a thirty (30) day month. Sublandlord and Subtenant
shall acknowledge in writing the Sublease Commencement Date.

          5. Operating Expenses and Other Rent. Subtenant shall have no
obligation to pay any portion of the Building's Operating Expenses, Real
Property Taxes, or insurance costs, and the terms and provisions of Sections 5,
6, and 7 of the Master Lease are not deemed to be incorporated into this
Sublease.

          6. As-Is Condition of Subpremises. Except for the obligation of
Sublandlord to erect a demising wall as specified in Section 14 of this
Sublease, notwithstanding any other contrary provision of this Sublease or the
Master Lease, Sublandlord shall deliver the Subpremises to Subtenant in an
"as-is" with all faults condition, and Sublandlord shall not be obligated to
make any repairs, restoration, alterations or improvements to the Subpremises in
connection with Subtenant's occupancy thereof other than as expressly set forth
herein. Subtenant acknowledges that Sublandlord has made no representation or
warranty to Subtenant regarding the condition of the Subpremises or the
suitability thereof for Subtenant's purposes.


                                       2

     7.   Security Deposit. Concurrent with the execution and delivery of this
Sublease, Subtenant shall pay the Sublandlord a security deposit in the amount
of $3,495.75. Such security deposit shall be delivered to Sublandlord to secure
the faithful performance by Subtenant of its obligations under this Sublease.
Sublandlord shall hold and administer such security deposit in accordance with
the terms and provisions set forth in Section 3.3 of the Master Lease, and such
terms will apply to the security deposit delivered by Subtenant pursuant to the
terms of this Sublease.

     8.   Use. Subtenant covenants and agrees to use the Subpremises solely for
the Permitted Use set forth in the Master Lease and otherwise in accordance
with and subject to the provisions of the Master Lease.

     9.   Master Lease.

          9.1  Relationship of Sublease to Master Lease. Subtenant acknowledges
that this Sublease is subject and subordinate to the Master Lease and to all of
the terms, covenants and conditions set forth therein. Subtenant covenants and
agrees during the Term of this Sublease to perform and observe all of the terms,
covenants, conditions and agreements set forth in the Master Lease to be
performed by or which are applicable to, Sublandlord, as tenant, to the extent
that such terms, covenants, conditions and agreements are not expressly modified
or amended by this Sublease, and provided further, that such are limited to the
Subpremises only (as opposed to the entire Premises or the entire Additional
Premises.) Without limiting the foregoing, and notwithstanding the provisions
Section 16.6 of the Master Lease to the contrary, in no event shall Subtenant be
liable for the payment of any Base Rent or Additional Rent under the terms of
the Master Lease other than Subtenant's obligation to pay the Base Rent set
forth in this Sublease. Subtenant shall not do or suffer or permit anything to
be done which would constitute a breach or default under the Master Lease or
might cause the Master Lease to be terminated, canceled or forfeited.

          9.2  Incorporation of Master Lease. Except to the extent the terms and
conditions set forth in this Sublease expressly modify or contradict the terms
and conditions of the Master Lease, all of the terms and conditions set forth in
the Master Lease are hereby incorporated into and made a part of this Sublease.
For purposes of such incorporation, all references in the Master Lease to
"Landlord" shall mean and refer to Sublandlord and all references in the Master
Lease to "Tenant" shall mean and refer to Subtenant. Except as otherwise
expressly provided in this Sublease, the rights and obligations of the Landlord
and the Tenant under the Master Lease shall be deemed the rights and obligations
of Sublandlord and Subtenant, respectively, hereunder, and shall be binding upon
and inure to the benefit of Sublandlord and Subtenant, respectively. As between
the parties to this Sublease only, in the event of a conflict between the terms
of the Master Lease and the terms of this Sublease, the terms of this Sublease
shall control.

          9.3  Landlord's Performance Under Master Lease. Notwithstanding any
contrary provision of this Sublease, Subtenant recognizes, understands and
agrees that Sublandlord is not in a position to render any of the services or
to perform any of the obligations of Master Landlord under the Master Lease
which have otherwise been incorporated herein. Therefore, notwithstanding
anything to the contrary set forth in this Sublease, Sublandlord shall


                                       3
<PAGE>
in no event be liable to Subtenant for any covenants, obligations, indemnities,
representations or warranties to be performed or provided by Master Landlord
under the Master Lease, nor shall any failure or delay on the Master Landlord's
part in the performance of any such covenants, obligations, indemnities,
representations or warranties excuse the performance by Subtenant of its
obligations under this Sublease, including, without limitation, the obligation
to pay Rent, nor permit Subtenant to terminate this Sublease or any of its
obligations hereunder, provided, however, Subtenant shall be entitled to
participate with Sublandlord in the enforcement of Sublandlord's rights against
the Master Landlord under the Master Lease, and, at Subtenant's written request,
Sublandlord shall take commercially reasonable steps, at Subtenant's expense, to
enforce Sublandlord's rights against Master Landlord. Notwithstanding the
foregoing, if as a result of a breach or default by Master Landlord under the
Master Lease, Sublandlord has the right to abate its Rent payable thereunder, or
a portion thereof, then Subtenant shall have the same right under this Sublease
to the extent of Sublandlord's rights under the Master Lease. If Sublandlord
shall take or participate or assist in, or shall be requested to take,
participate or assist in, any actions to enforce Sublandlord's rights against
the Master Landlord, in so far as they are connected to or affect the
Subpremises. Subtenant agrees to be responsible for all costs, expenses and
other amounts incurred by Sublandlord in connection therewith, including,
without limitation, attorneys' and/or consultants' fees and other costs of suit,
if they are solely related to the Subpremises, or its proportionate share of
such costs and expenses, to the extent that such actions also relate to other
portion of the Premises under the Master Lease. Subtenant agrees to indemnify,
defend and hold Sublandlord harmless from and against any and all liabilities,
damages, claims, losses, costs and expenses (including, without limitation,
reasonable attorneys' fees) incurred by or brought against Sublandlord as a
result of or in connection with any actions or proceedings taken or instituted
by Subtenant (or by Sublandlord at Subtenant's request) to enforce Sublandlord's
rights and remedies under the Master Lease, whether or not Sublandlord joins
therein.

          9.4 Sublandlord Covenants. Sublandlord covenants and agrees (i) not
to voluntarily terminate the Master Lease, (ii) not to modify the Master Lease
so as to adversely affect Subtenant's rights hereunder, and (iii) to take all
actions reasonably necessary to preserve the Master Lease.

     10. Indemnification. Subtenant hereby agrees to indemnify, defend and hold
Sublandlord harmless from and against any and all claims, losses, damages,
liabilities, costs and expenses (including, without limitation, reasonable
attorneys' fees and disbursements) incurred by or brought or asserted against
Sublandlord arising out of or related to (a) Subtenant's breach or failure to
perform or comply with any covenants, agreements, terms or conditions of this
Sublease or the Master Lease; (b) Subtenant's use or occupancy of the
Subpremises; and/or (c) any activity, or thing done, permitted to be done or
suffered by Subtenant, its agents, employees, contractors, invitees, licensees,
successors or assigns in or about the Subpremises or Building. The terms and
provisions of this Section 10 shall survive the expiration or earlier
termination of the Sublease and/or the Master Lease.

     11. Consents and Approvals. Whenever in the Master Lease the Master
Landlord  is required to obtain the consent or approval of Sublandlord with
respect to a matter, Sublandlord shall not grant such consent or approval
without first informing Subtenant of such matter (unless Master Landlord has
notified Subtenant with respect thereto), and obtaining

                                       4


<PAGE>


Subtenant's consent or approval to the matter. Subtenant shall be required to
notify Sublandlord in writing of its decision as to such requested consent or
approval within the time frames for Sublandlord's response under the Master
Lease, failing which Sublandlord alone shall have the right to grant or deny the
requested consent or approval. Whenever in the Master Lease the consent or
approval of the Master Landlord shall be required with respect to a matter,
Subtenant shall obtain such consent or approval from both Master Landlord and
Sublandlord. The standards for the granting or withholding of any consent or
approval under the Master Lease or this Sublease shall be as set forth with
respect to such matter in the Master Lease.

     12.  Notices. All notices and other communications in connection with this
Sublease shall be made in accordance with the terms of the Master Lease.
Sublandlord's address for notice purposes shall be "Tenant's Address" under the
Master Lease. Subtenant's address for notice purposes shall be as follows:

separate agreement between Sublandlord and its broker.

        16. Severability. If any term or provision of this Sublease or the
application thereof to any person or circumstance shall, to any extent, be
invalid and unenforceable, the remainder of this Sublease or the application of
