                  ValueClick, Inc. (the "Registrant") hereby incorporates by
reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "Commission"):

(a)      The Registrant's prospectus filed with the Commission pursuant to Rule
         424(b) promulgated under the Securities Act of 1933, as amended (the
         "1933 Act") filed with the SEC on March 31, 2000, in connection with
         the Registrant's Registration Statement No. 333-88765 on Form S-1, in

(b)      The Registrant's Registration Statement on Form 8-A12G filed with the
         SEC on March 28, 2000, in which are described the terms, rights and
         provisions applicable to the Registrant's outstanding Common Stock;
         and

(c)      The Registrant's Quarterly Report on Form 10-Q filed with the
         Commission on May 15, 2000 for the quarterly period ended March 31,
         2000.

                  All reports and definitive proxy or information statements
filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange
Act of 1934, as amended (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 de-registers 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

superseded for purposes of this Registration Statement to the extent that a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 Any such statement so modified or superseded shall not be deemed,
except as so modified or superseded, to constitute a part of this Registration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 SECURITIES

                  Not Applicable.

Item 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

                  Not Applicable.

Item 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

                  Section 145 of the Delaware General Corporation Law permits
indemnification of officers and directors of the Registrant under certain
conditions and subject to certain limitations. Section 145 of the Delaware
General Corporation Law also provides that a corporation has the power to
purchase and maintain insurance on behalf of its officers and directors against
any liability asserted against such person and incurred by him or her in such
capacity, or arising out of his or her status as such, whether or not the
corporation would have the power to indemnify him or her against such liability
under the provisions of Section 145 of the Delaware General Corporation Law.

                  Article VII, Section I of the Bylaws of the Registrant
provides that the Registrant shall indemnify its directors and executive
officers to the fullest extent permitted by the Delaware General Corporation
Law. The rights to indemnity thereunder continue as to a person who has ceased
to be a director, officer, employee or agent and inure to the benefit of the
heirs, executors and administrators of the person. In addition, expenses
incurred by a

                                     II-1

<PAGE>

director or executive officer in defending any civil, criminal,
administrative or investigative action, suit or proceeding by reason of the
fact that he or she is or was a director or officer of the Registrant (or was
serving at the Registrant's request as a director or officer of another
corporation) shall be paid by the Registrant in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking
by or on behalf of such director or officer to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by
the Registrant as authorized by the relevant section of the Delaware General
Corporation Law.

                  As permitted by Section 102(b)(7) of the Delaware General
Corporation Law, Article VIII of the Registrant's Amended and Restated
Certificate of Incorporation provides that a director of the Registrant shall
not be personally liable for monetary damages for breach of fiduciary duty as
a director, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or its stockholders, (ii) for acts or omissions not
in good faith or acts or omissions that involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law or (iv) for any transaction from which the director derived
any improper personal benefit.

                  The Registrant has entered into indemnification agreements
with each of its directors and executive officers. Generally, the
indemnification agreements attempt to provide the maximum protection
permitted by Delaware law as it may be amended from time to time. Moreover,
the indemnification agreements provide for certain additional
indemnification. Under such additional indemnification provisions, however,
an individual will not receive indemnification for judgments, settlements or
expenses if he or she is found liable to the Registrant (except to the extent
the court determines he or she is fairly and reasonably entitled to indemnity
for expenses). The indemnification agreements provide for the Registrant to
advance to the individual any and all reasonable expenses (including legal
fees and expenses) incurred in investigating or defending any such action,
suit or proceeding. In order to receive an advance of expenses, the
individual must submit to the Registrant a statement or statements that
reasonably evidences such expenses. Also, the individual must repay such
advances upon a final judicial decision that he or she is not entitled to
indemnification.

                  The Registrant has purchased directors' and officers'
liability insurance.

Item 7.  EXEMPTION FROM REGISTRATION CLAIMED

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

                                     II-2

<PAGE>

prospectus required by Section 10(a)(3) of 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 clauses 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 this
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 at the termination of the Registrant's 1999 Stock Option Plan granted
to certain individuals.

                  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 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 or controlling persons of
the Registrant pursuant to the indemnification provisions summarized in Item 6
or otherwise, the Registrant has been advised that, in the opinion of the
Commission, 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.

                  ValueClick, Inc. (the "Registrant") hereby incorporates by
reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "Commission"):

(a)      The Registrant's prospectus filed with the Commission pursuant to Rule
         424(b) promulgated under the Securities Act of 1933, as amended (the
         "1933 Act") filed with the SEC on March 31, 2000, in connection with
         the Registrant's Registration Statement No. 333-88765 on Form S-1, in
         which there is set forth the audited financial statements for the
         Registrant's fiscal year ended December 31, 1999;

(b)      The Registrant's Registration Statement on Form 8-A12G filed with the
         SEC on March 28, 2000, in which are described the terms, rights and
         provisions applicable to the Registrant's outstanding Common Stock;
         and

(c)      The Registrant's Quarterly Report on Form 10-Q filed with the
         Commission on May 15, 2000 for the quarterly period ended March 31,
         2000.

                  All reports and definitive proxy or information statements
filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange
Act of 1934, as amended (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 de-registers 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 SECURITIES

                  Not Applicable.

Item 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

                  Not Applicable.

Item 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

                  Section 145 of the Delaware General Corporation Law permits
indemnification of officers and directors of the Registrant under certain
conditions and subject to certain limitations. Section 145 of the Delaware
General Corporation Law also provides that a corporation has the power to
purchase and maintain insurance on behalf of its officers and directors against
any liability asserted against such person and incurred by him or her in such
capacity, or arising out of his or her status as such, whether or not the
corporation would have the power to indemnify him or her against such liability
under the provisions of Section 145 of the Delaware General Corporation Law.

                  Article VII, Section I of the Bylaws of the Registrant
provides that the Registrant shall indemnify its directors and executive
officers to the fullest extent permitted by the Delaware General Corporation
Law. The rights to indemnity thereunder continue as to a person who has ceased
to be a director, officer, employee or agent and inure to the benefit of the
heirs, executors and administrators of the person. In addition, expenses
incurred by a

                                     II-1
director or executive officer in defending any civil, criminal,
administrative or investigative action, suit or proceeding by reason of the
fact that he or she is or was a director or officer of the Registrant (or was
serving at the Registrant's request as a director or officer of another
corporation) shall be paid by the Registrant in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking
by or on behalf of such director or officer to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by
the Registrant as authorized by the relevant section of the Delaware General
Corporation Law.

                  As permitted by Section 102(b)(7) of the Delaware General
Corporation Law, Article VIII of the Registrant's Amended and Restated
Certificate of Incorporation provides that a director of the Registrant shall
not be personally liable for monetary damages for breach of fiduciary duty as
a director, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or its stockholders, (ii) for acts or omissions not
in good faith or acts or omissions that involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law or (iv) for any transaction from which the director derived
any improper personal benefit.

                  The Registrant has entered into indemnification agreements
with each of its directors and executive officers. Generally, the
indemnification agreements attempt to provide the maximum protection
permitted by Delaware law as it may be amended from time to time. Moreover,
the indemnification agreements provide for certain additional
indemnification. Under such additional indemnification provisions, however,
an individual will not receive indemnification for judgments, settlements or
expenses if he or she is found liable to the Registrant (except to the extent
the court determines he or she is fairly and reasonably entitled to indemnity
for expenses). The indemnification agreements provide for the Registrant to
advance to the individual any and all reasonable expenses (including legal
fees and expenses) incurred in investigating or defending any such action,
suit or proceeding. In order to receive an advance of expenses, the
individual must submit to the Registrant a statement or statements that
reasonably evidences such expenses. Also, the individual must repay such
advances upon a final judicial decision that he or she is not entitled to
indemnification.

                  The Registrant has purchased directors' and officers'
liability insurance.

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

                                     II-2
prospectus required by Section 10(a)(3) of 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 clauses 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 this
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 at the termination of the Registrant's 1999 Stock Option Plan granted
to certain individuals.

                  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 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 or controlling persons of
the Registrant pursuant to the indemnification provisions summarized in Item 6
or otherwise, the Registrant has been advised that, in the opinion of the
Commission, 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.

duly caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of Carpinteria, State of
California on this 31st day of May 2000.
