     The following documents filed by iPayment, Inc. (the "Company") are

     (i)  The Company's prospectus filed with the Commission on May 13, 2003
          pursuant to Rule 424(b)(4) under the Securities Act in connection with
          the Company's Registration Statement on Form S-1 (File No.

    (ii)  The Company's Form 10-Q for the three month period ended March 31,
          2003, filed with the Commission on June 17, 2003.

   (iii)  The description of the Company's shares of Common Stock contained in
          Item 1 of the Registration Statement on Form 8-A (File No. 000-50280)
          filed with the Commission on May 7, 2003.

     In addition to the foregoing, all documents subsequently filed by the
Company pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), prior to the filing of a
post-effective amendment indicating that all securities offered hereby have been
sold or deregistering all securities then remaining unsold, shall be deemed to
be incorporated by reference in this Registration Statement and to be a part
hereof from the date of filing of such documents. Any statement contained herein
or in a document all or a portion of which is incorporated or deemed to be
incorporated by reference herein shall be deemed to be modified or superseded
for purposes of this Registration Statement to the extent that a statement
contained herein or in any other subsequently filed document which also is or is
deemed to be incorporated by reference herein modifies or supersedes such
statement. Any such statement so modified or superseded shall not be deemed,
except as so modified or superseded, to constitute a part of this Registration
Statement.

Item 4.   Description of Securities.

     Not applicable.

Item 5.   Interests of Named Experts and Counsel.

     The validity of the shares of Common Stock being registered pursuant to
this Registration Statement will be passed upon for the Company by White & Case
LLP. As of the date of this Registration Statement, one individual affiliated
with White & Case LLP beneficially owns warrants to purchase an aggregate of
54,506 shares of the Registrant's Common Stock.

Item 6.   Indemnification of Directors and Officers.

     Section 145 of the Delaware General Corporation Law provides that a
Delaware corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that the person is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include
<PAGE>

expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person in connection with the
action, suit, or proceeding, provided the person acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the
corporation's best interests and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that the person's conduct was
unlawful. A similar standard of care is applicable in the case of actions by or
in the right of the corporation, except that no indemnification may be made in
respect of any claim, issue or matter as to which such person will have been
adjudged to be liable to the corporation unless and only to the extent that the
Delaware Court of Chancery or the court in which such action was brought
determines that, despite the adjudication of liability but in view of all of the
circumstances of the case, the person is fairly and reasonably entitled to
indemnity for expenses that the Delaware Court of Chancery or other court shall
deem proper.

     The Registrant's certificate of incorporation and bylaws provide that it
will indemnify and advance expenses to its directors, officers and employees to
the fullest extent permitted by Delaware law in connection with any threatened,
pending or completed action, suit or proceeding to which such person was or is a
party or is threatened to be made a party by reason of the fact that he or she
is or was a director, officer or employee, or is or was serving at the
Registrant's request as a director, officer, employee or agent of another
corporation or enterprise. In connection with the foregoing, we have entered
into agreements with each of our directors and officers pursuant to which we
have agreed to indemnify and advance expenses to them.

     We have purchased directors' and officers' liability insurance policy to
insure our directors and officers against liability for actions or omissions
occurring in their capacity as a director or officer, subject to certain
exclusions and limitations.

Item 7.   Exemption from Registration Claimed.

     Not applicable.

Item 8.   Exhibits.

     The exhibits listed on the exhibit index at the end of this Registration
Statement are included in this Registration Statement.

Item 9.   Undertakings.

     The undersigned Registrant, iPayment, Inc., hereby undertakes:

     (1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

     (i)  to include any prospectus required by Section 10(a)(3) of the
          Securities Act;

    (ii)  to reflect in the prospectus any facts or events arising after the
          effective date of this Registration Statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in this Registration Statement. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume

                                      -2-
<PAGE>

          and price represent no more than a 20 percent change in the maximum
          aggregate offering price set forth in the "Calculation of Registration
          Fee" table in the effective registration statement; and

   (iii)  to include any material information with respect to the plan of
          distribution not previously disclosed in this Registration Statement
          or any material change to such information in this Registration
          Statement.

     provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the Registrant
     pursuant to Sections 13 or 15(d) of the Exchange Act that are incorporated
     by reference in this Registration Statement;

     (2) that, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof;

     (3) to remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering; and

     (4) that, for purposes of determining any liability under the Securities
Act, each filing of the Registrant's annual report pursuant to Sections 13(a) or
15(d) of the Exchange Act and each filing of annual reports of each of the Stock
Incentive Plan and the Non-Employee Directors Stock Option Plan pursuant to
Section 15(d) of the Exchange Act that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
