by 85%, the percentage of the fair market value of the stock that is used to

                     Form 8-A filed with the Commission on November 3, 1999,

         All reports and definitive proxy or information statements filed
pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act (the "1934
Act") after the date of this Registration Statement and prior to the filing of a

deemed to be incorporated by reference into this Registration Statement and to
be a part hereof from the date of filing of such documents. Any statement
contained in a document 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herein shall be deemed to be modified or superseded for purposes of this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
subsequently filed document which also is deemed to be incorporated by reference

superseded shall not be deemed, except as so modified or superseded, to
constitute a part of this Registration Statement.


Item 4. Description of Capital Stock

                   Not Applicable.


Item 5. Interests of Named Experts and Counsel

                   Not Applicable.


Item 6. Indemnification of Directors and Officers

         As permitted by the New York Business Corporation Law, our restated
certificate of incorporation provides that a director will not be personally
liable to us or our shareholders for damages for any breach of duty in his or
her capacity as a director unless a judgment or other final adjudication adverse
to such director establishes that (1) his or her acts or omissions were in bad
faith or involved intentional misconduct or a knowing violation of law, (2) such
director personally gained in fact a financial profit or other advantage to
which he or she was not legally entitled or (3) his or her acts violated Section
719 of the New York Business Corporation Law.



                                        3
<PAGE>

         This provision is intended to afford directors protection, and limit
their potential liability, from suits alleging a breach of the duty of care by a
director. We believe this provision will assist us in maintaining and securing
the services of directors who are not employees of NetCreations. As a result of
the inclusion of such a provision, shareholders may be unable to recover
monetary damages against directors for actions taken by them that constitute
negligence or gross negligence or that are in violation of their fiduciary
duties, although it may be possible to obtain injunctive or other equitable
relief with respect to those actions. If equitable remedies are found not to be
available to shareholders for any particular case, shareholders may not have any
effective remedy against the challenged conduct This provision does not affect
the directors' responsibilities, under any other laws, such as the Federal
securities laws or state or Federal environmental laws.

         Our restated certificate of incorporation also provides that directors
and officers shall be indemnified against liabilities arising from their service
as directors or officers to the fullest extent permitted by law, which generally
requires that the individual have acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to NetCreations' best interests. No
indemnification may be made to or on behalf of any directors or officers if a
judgment or other final adjudication adverse to him or her established that his
or her acts were committed in bad faith or were the result of active and
deliberate dishonesty and were material to the cause of action so adjudicated,
or that he or she personally gained in fact a financial profit or other
advantage to which he or she was not legally entitled.

         New York law provides further that the indemnification permitted under
New York law shall not be deemed exclusive of any other rights to which the
directors and officers may be entitled under our bylaws, any agreement, a vote
of shareholders or otherwise.

         We have also entered into agreements to indemnify our directors and
executive officers, in addition to the indemnification provided for in our
bylaws. We believe that these provisions and agreements are necessary to attract
and retain qualified directors and executive officers. Our bylaws also permit us
to secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions, regardless of whether New
York law would permit indemnification. We have obtained directors' and officers'
liability insurance for our officers and directors.

         At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under our restated certificate of incorporation, bylaws,
or any indemnification agreement. We are not aware of any threatened litigation
or proceeding that may result in a claim for such indemnification.

Item 9. Undertakings

                  A. The undersigned Registrant 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 of 1933, as amended (the "1933 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,
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 clauses (1)(i) and (1)(ii) shall 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 Section 13 or
Section 15(d) of the 1934 Act that are incorporated by reference into the
registration statement; (2) that for the purpose of determining any liability
under the 1933 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; and (3) to remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold upon the termination of the 1997 Stock Incentive Plan.

                  B. The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Securities and Exchange Act of
1934) that is incorporated by reference into 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.

                  C. Insofar as indemnification for liabilities arising under
the 1933 Act may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the indemnification provisions summarized in Item 6
above, or otherwise, the Registrant has been advised that in the opinion of the
SEC such indemnification is against public policy as expressed in the 1933 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 1933 Act and will be governed by the final
adjudication of such issue.

into this Registration Statement the following documents previously filed with
the Securities and Exchange Commission (the "SEC"):

         (a)         The Registrant's Annual Report on Form 10-K for the fiscal
                     year ended December 31, 1999 filed with the SEC on March

                     12, 2000;

         (c)         The Registrant's Current Reports on Form 8-K filed with the
                     SEC on June 9, 2000; and

         (d)         The Registrant's Registration Statement No. 000-27923 on
                     Form 8-A filed with the Commission on November 3, 1999,
                     including any other amendments or reports filed for the
                     purpose of updating such description in which there is
                     described the terms, rights and provisions applicable to
                     the Registrant's Common Stock.

         All reports and definitive proxy or information statements filed
pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act (the "1934
Act") after the date of this Registration Statement and prior to the filing of a
post-effective amendment which indicates that all securities offered hereby have
been sold or which deregisters all securities then remaining unsold shall be
deemed to be incorporated by reference into this Registration Statement and to
be a part hereof from the date of filing of such documents. Any statement
contained in a document 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
subsequently filed document which also 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 Capital Stock

                   Not Applicable.

Item 5. Interests of Named Experts and Counsel

                   Not Applicable.

Item 6. Indemnification of Directors and Officers

         As permitted by the New York Business Corporation Law, our restated
certificate of incorporation provides that a director will not be personally
liable to us or our shareholders for damages for any breach of duty in his or
her capacity as a director unless a judgment or other final adjudication adverse
to such director establishes that (1) his or her acts or omissions were in bad
faith or involved intentional misconduct or a knowing violation of law, (2) such
director personally gained in fact a financial profit or other advantage to
which he or she was not legally entitled or (3) his or her acts violated Section
719 of the New York Business Corporation Law.

                                        3
This provision is intended to afford directors protection, and limit
their potential liability, from suits alleging a breach of the duty of care by a
director. We believe this provision will assist us in maintaining and securing
the services of directors who are not employees of NetCreations. As a result of
the inclusion of such a provision, shareholders may be unable to recover
monetary damages against directors for actions taken by them that constitute
negligence or gross negligence or that are in violation of their fiduciary
duties, although it may be possible to obtain injunctive or other equitable
relief with respect to those actions. If equitable remedies are found not to be
available to shareholders for any particular case, shareholders may not have any
effective remedy against the challenged conduct This provision does not affect
the directors' responsibilities, under any other laws, such as the Federal
securities laws or state or Federal environmental laws.

         Our restated certificate of incorporation also provides that directors
and officers shall be indemnified against liabilities arising from their service
as directors or officers to the fullest extent permitted by law, which generally
requires that the individual have acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to NetCreations' best interests. No
indemnification may be made to or on behalf of any directors or officers if a
judgment or other final adjudication adverse to him or her established that his
or her acts were committed in bad faith or were the result of active and
deliberate dishonesty and were material to the cause of action so adjudicated,
or that he or she personally gained in fact a financial profit or other
advantage to which he or she was not legally entitled.

         New York law provides further that the indemnification permitted under
New York law shall not be deemed exclusive of any other rights to which the
directors and officers may be entitled under our bylaws, any agreement, a vote
of shareholders or otherwise.

         We have also entered into agreements to indemnify our directors and
executive officers, in addition to the indemnification provided for in our
bylaws. We believe that these provisions and agreements are necessary to attract
and retain qualified directors and executive officers. Our bylaws also permit us
to secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions, regardless of whether New
York law would permit indemnification. We have obtained directors' and officers'
liability insurance for our officers and directors.

         At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under our restated certificate of incorporation, bylaws,
or any indemnification agreement. We are not aware of any threatened litigation
or proceeding that may result in a claim for such indemnification.

Item 9. Undertakings

                  A. The undersigned Registrant 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 of 1933, as amended (the "1933 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,
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 clauses (1)(i) and (1)(ii) shall 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 Section 13 or
Section 15(d) of the 1934 Act that are incorporated by reference into the
registration statement; (2) that for the purpose of determining any liability
under the 1933 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; and (3) to remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold upon the termination of the 1997 Stock Incentive Plan.

                  B. The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Securities and Exchange Act of
1934) that is incorporated by reference into 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.

                  C. Insofar as indemnification for liabilities arising under
the 1933 Act may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the indemnification provisions summarized in Item 6
above, or otherwise, the Registrant has been advised that in the opinion of the
SEC such indemnification is against public policy as expressed in the 1933 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 1933 Act and will be governed by the final
adjudication of such issue.
