                INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The following documents filed by Evoke Communications, Inc. (the "Company")
with the Securities and Exchange Commission (the "Commission") are incorporated
by reference into this Registration Statement:

     (a)  The Registrant's Prospectus dated July 24, 2000 filed pursuant to Rule
424(b) under the Securities Act that contains audited financial statements for
the Registrant's latest fiscal year for which such statements have been filed
and a description of the Registrant's Common Stock.

     (b)  All reports and other documents filed by the Registrant with the
Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") after the date of this
Registration Statement and prior to the filing of a post-effective amendment
which indicates that all of the securities offered hereby have been sold or
which deregisters all such securities then remaining unsold.

     (c)  The description of the Company's Common Stock contained in the
Registrant's Registration Statement on Form S-1 (File No. 000-30708) filed under
the Securities Act, including any amendment or report filed for the purpose of
updating such description.

          Any statement contained in a document incorporated, or deemed to be
incorporated, by reference herein or contained in this Registration Statement
shall be deemed to be modified or superseded for purposes of this Registration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modified or superseded shall not be deemed, except as so modified or superseded,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.

                           DESCRIPTION OF SECURITIES

     Not Applicable.

                    INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not Applicable.

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Registrant's Restated Certificate of Incorporation provides to the
fullest extent permitted by Delaware law, the Registrant's directors will not be
liable for monetary damages for breach of the directors' fiduciary duty to the
Registrant and its stockholders.  Delaware law provides that directors of a
corporation will not be personally liable for monetary damages for breach of
their fiduciary duties as directors except liability for breach of their duty of
loyalty to the corporation or its stockholders, acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
unlawful payments of dividends or unlawful stock repurchases or redemptions, or
any transaction from which the director derived an improper personal benefit.
Such limitation of liability does not apply to liabilities arising under the
federal or state securities laws and does not affect the availability of
equitable remedies such as injunctive relief or rescission.

     The Registrant's Bylaws provide that it shall indemnify its directors and
executive officers and may indemnify other officers, employees and agents to the
fullest extent permitted by law. The Registrant's Bylaws also permit it to
secure insurance on behalf of any person required or permitted to be
indemnified.

     The Registrant has entered into indemnity agreements with each of its
directors and executive officers under which each director and executive officer
will be indemnified against expenses and losses incurred for claims brought
against them by reason of their being a director or executive officer of
Registrant.  Registrant's board of directors has authorized the officers of
Registrant to investigate and obtain directors' and officers' liability
insurance.

</TABLE>

                                 UNDERTAKINGS

1.   The undersigned registrant hereby undertakes:

     (a)  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 the 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 the 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) (Section 230.424(b) of this
chapter) if, in the aggregate, the changes in volume and price represent no more
than a 20%

                                       4
<PAGE>

change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement.

          (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

     Provided, however, that paragraphs (a)(i) and (a)(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 with or furnished to the
Commission by the Registrant pursuant to section 13 or section 15(d) of the
Exchange Act that are incorporated by reference herein.

     (b)  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 herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (c)  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.

2.   The undersigned registrant hereby undertakes that, for purposes of
     determining any liability under the Securities Act, each filing of the
     registrant's annual report pursuant to Section 13(a) or Section 15(d) of
     the Exchange Act (and, where applicable, each filing of an employee benefit
     plan's annual report pursuant to section 15(d) of the Exchange Act) that is
     incorporated by reference in the Registration Statement shall be deemed to
     be a new registration statement relating to the securities offered herein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

3.   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 Securities and
     Exchange 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.

INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

     The following documents filed by Evoke Communications, Inc. (the "Company")
with the Securities and Exchange Commission (the "Commission") are incorporated
by reference into this Registration Statement:

     (a)  The Registrant's Prospectus dated July 24, 2000 filed pursuant to Rule
424(b) under the Securities Act that contains audited financial statements for
the Registrant's latest fiscal year for which such statements have been filed
and a description of the Registrant's Common Stock.

     (b)  All reports and other documents filed by the Registrant with the
Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") after the date of this
Registration Statement and prior to the filing of a post-effective amendment
which indicates that all of the securities offered hereby have been sold or
which deregisters all such securities then remaining unsold.

     (c)  The description of the Company's Common Stock contained in the
Registrant's Registration Statement on Form S-1 (File No. 000-30708) filed under
the Securities Act, including any amendment or report filed for the purpose of
updating such description.

          Any statement contained in a document incorporated, or deemed to be
incorporated, by reference herein or contained in this Registration Statement
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.

                           DESCRIPTION OF SECURITIES

     Not Applicable.

                    INTERESTS OF NAMED EXPERTS AND COUNSEL

     Not Applicable.

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Registrant's Restated Certificate of Incorporation provides to the
fullest extent permitted by Delaware law, the Registrant's directors will not be
liable for monetary damages for breach of the directors' fiduciary duty to the
Registrant and its stockholders.  Delaware law provides that directors of a
corporation will not be personally liable for monetary damages for breach of
their fiduciary duties as directors except liability for breach of their duty of
loyalty to the corporation or its stockholders, acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
unlawful payments of dividends or unlawful stock repurchases or redemptions, or
any transaction from which the director derived an improper personal benefit.
Such limitation of liability does not apply to liabilities arising under the
federal or state securities laws and does not affect the availability of
equitable remedies such as injunctive relief or rescission.

     The Registrant's Bylaws provide that it shall indemnify its directors and
executive officers and may indemnify other officers, employees and agents to the
fullest extent permitted by law. The Registrant's Bylaws also permit it to
secure insurance on behalf of any person required or permitted to be
indemnified.

     The Registrant has entered into indemnity agreements with each of its
directors and executive officers under which each director and executive officer
will be indemnified against expenses and losses incurred for claims brought
against them by reason of their being a director or executive officer of
Registrant.  Registrant's board of directors has authorized the officers of
Registrant to investigate and obtain directors' and officers' liability
insurance.

UNDERTAKINGS

1.   The undersigned registrant hereby undertakes:

     (a)  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 the 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 the 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) (Section 230.424(b) of this
chapter) if, in the aggregate, the changes in volume and price represent no more
than a 20%

                                       4
change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement.

          (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

     Provided, however, that paragraphs (a)(i) and (a)(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 with or furnished to the
Commission by the Registrant pursuant to section 13 or section 15(d) of the
Exchange Act that are incorporated by reference herein.

     (b)  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 herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (c)  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.

2.   The undersigned registrant hereby undertakes that, for purposes of
     determining any liability under the Securities Act, each filing of the
     registrant's annual report pursuant to Section 13(a) or Section 15(d) of
     the Exchange Act (and, where applicable, each filing of an employee benefit
     plan's annual report pursuant to section 15(d) of the Exchange Act) that is
     incorporated by reference in the Registration Statement shall be deemed to
     be a new registration statement relating to the securities offered herein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

3.   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 Securities and
     Exchange 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.

                                       5
