         (b)      The description of the Common Stock of Interliant contained in
                  the Registration Statement; such description is qualified in
                  its entirety by reference to the (i) Amended and Restated
                  Certificate of Incorporation of Interliant, filed with the

                  Registration Statement, and any amendment or report filed for

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Interliant is a Delaware corporation. Reference is made to Section 145
of the Delaware General Corporation Law as to indemnification by Interliant of
its officers and directors. The general effect of such law is to empower a
corporation to indemnify any of its officers and directors against certain
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person to be indemnified in
connection with certain actions, suits or proceedings (threatened, pending or
completed) if the person to be indemnified acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

         Interliant's Amended and Restated Certificate of Incorporation and
Amended and Restated By-laws provide that Interliant shall indemnify officers
and directors and, to the extent permitted by the Board of Directors, employees
and agents of Interliant, to the full extent permitted by and in the manner
permissible under the laws of the State of Delaware. In addition, the By-Laws
permit the Board of Directors to authorize Interliant to purchase and maintain
insurance against any liability asserted against any director, officer, employee
or agent of Interliant arising out of his capacity as such.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

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;

                  (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; and

                  (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;
<PAGE>   6
provided, however, that paragraphs (a)(1)(i) and (a)(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 with or furnished to the
Securities and Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, 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.

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

         (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 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 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 Act and will
be governed by the final adjudication of such issue.

Registration Statement to be signed on its behalf by the undersigned, thereunto

                  the Registration Statement; such description is qualified in
                  its entirety by reference to the (i) Amended and Restated
                  Certificate of Incorporation of Interliant, filed with the

                  Registration Statement, and any amendment or report filed for

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Interliant is a Delaware corporation. Reference is made to Section 145
of the Delaware General Corporation Law as to indemnification by Interliant of
its officers and directors. The general effect of such law is to empower a
corporation to indemnify any of its officers and directors against certain
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person to be indemnified in
connection with certain actions, suits or proceedings (threatened, pending or
completed) if the person to be indemnified acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

         Interliant's Amended and Restated Certificate of Incorporation and
Amended and Restated By-laws provide that Interliant shall indemnify officers
and directors and, to the extent permitted by the Board of Directors, employees
and agents of Interliant, to the full extent permitted by and in the manner
permissible under the laws of the State of Delaware. In addition, the By-Laws
permit the Board of Directors to authorize Interliant to purchase and maintain
insurance against any liability asserted against any director, officer, employee
or agent of Interliant arising out of his capacity as such.

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;

                  (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; and

                  (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;
6
provided, however, that paragraphs (a)(1)(i) and (a)(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 with or furnished to the
Securities and Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, 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.

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

         (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 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 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 Act and will
be governed by the final adjudication of such issue.

Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of New York, State of New York, on the 20th day of
